摘要:
Objective: To study the effect of Baihe Dihuang Decoction in improving anxiety and its mechanism of action. Methods: Male mice were randomly divided into 5 groups: blank control group, Baihe Dihuang Decoction high, medium, low-dose group and diazepam group. After continuous intragastric administration for 14 d, the behavioral test of the mouse elevated plus maze experiment and opening test was performed. The brain tissue GABA and Glu content was measured by immunosorbent assay (ELISA). Results: Compared with the blank control group, the middle and high doses of Baihe Dihuang Decoction could increase the time and frequency of movement of the mice in the open cross labyrinth in the open arm and increase the number of times that the mouse entered the central area in the opening test. The anti-anxiety effect also showed an increase in the brain tissue GABA content in mice, ignificantly decreased Glu contents in mice. Conclusion: Baihe Dihuang Decoction has some anxiolytic effect, and antianxiety effect may be related to increasing brain tissue GABA content, decreased Glu contents in mice.

摘要:
Objective: The current study aims to identify the effects of exogenous application of pulsed electromagnetic fields on skin wound healing in diabetic rats, and thus provides experimental evidence for its more scientific clinical application in the future. Methods: The diabetic animal models were established via intraperitoneal injection of streptozotocin in 4-monthold male rats. Fourth eight rats were randomly assigned into the diabetes group (DM) and diabetes coupled with pulsed electromagnetic fields (DM+PEMF) group. Another 24 normal rats were used as the blank control group (Control). Then, all the rats in the three groups were subjected to dorsal surgery for the establishment of soft tissue wound model (circular wound with the diameter of 2 cm). Then, the rats in the DM+PEMF group were subjected to pulsed electromagnetic fields stimulation. Then, 6 rats in each group were sacrificed at Day 5, 12 and 19 post surgery. The glucose levels, wound closure, wound healing time and tissue tensile strength were examined and analyzed. Results: Pulsed electromagnetic fields significantly increased the wound closure rate in diabetic rats at Day 5, 12 and 19 post surgery, decreased overall wound healing period in diabetic rats, and also enhanced tissue tensile strength in diabetic rats at Day 5, 12 and 19 post surgery. Conclusion: Low-intensity pulsed electromagnetic fields can significantly accelerate diabetic wound healing process, and also improve diabetic tissue repair capacity. This study may be helpful for providing more scientific and reasonable experimental evidence for the treatment of pulsed electromagnetic fields on diabetic wound healing in clinics.

摘要:
Gastric cancer is one of common malignant tumors in clinic. It has high incidence, high mortality and poor prognosis. Generally, gastric cancer is divided into early gastric cancer (EGC) and advanced gastric cancer. The 5-year survival rate of EGC is higher than that of advanced gastric cancer. In recent years, with the continuous development of science and technology, a variety of medical instruments and technologies have been updated, greatly promoting the detection rate of EGC, reducing the rate of EGC missed diagnosis. This article reviews the progress of EGC endoscopic diagnosis.

摘要:
Objective: To investigate the effects of routine rehabilitation therapy combined with low frequency head stimulation on monoamine neurotransmitters, neuron-specific enolase (NSE), endothelin-1 (ET-1) and cerebral hemodynamics in children with cerebral palsy. Methods: From January 2017 to June 2018, 110 children with cerebral palsy were randomly divided into observation group (55 cases) and control group (55 cases). The control group received routine rehabilitation treatment, while the observation group received low-frequency head stimulation on the basis of routine rehabilitation treatment. The changes of dopamine (DA), norepinephrine (NE), serotonin (5-HT), NSE, ET-1 levels and mean blood flow velocity of anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior cerebral artery (PCA) were compared in two groups. Results: Before treatment, there was no significant difference in DA, NE and 5-HT levels in two groups. After treatment, DA, NE and 5-HT levels in the observation group were (192.23±22.71) ng/mL, (98.02±11.71) ng/L, (210.07±25.03) ng/L, and in the control group. the DA, NE, 5-HT levels were (147.06±17.02) ng/mL, (83.07±11.15) ng/L, and (171.88±20.45) ng/L, respectively. The DA, NE and 5-HT levels in two groups were higher than those before treatment, and DA, NE and 5-HT levels in the observation group were higher than those in the control group. Before treatment, there was no significant difference in NSE and ET-1 levels between the two groups. After treatment, the NSE and ET-1 levels in the observation group were (7.97±2.07) μg/L and (41.01±10.07) pg/ mL, and the NSE and ET-1 levels in the control group were (10.38±3.02) μg/L, (58.46±15.02) pg/ mL, respectively. the NSE and ET-1 in two groups were lower than those before treatment, and the NSE and ET-1 of the observation group were lower than the control group. Before treatment, there was no significant difference in mean blood flow velocity between ACA, MCA and PCA. After treatment, the mean blood flow velocities of ACA, MCA, and PCA in the observation group were (46.88±7.72) cm/s, (59.85±10.18) cm/s, and (49.15±7.02) cm/s, respectively, which was significantly higher than before treatment and higher than that of the control group in the same period. Conclusion: Conventional rehabilitation combined with low-frequency electrical stimulation of the head can effectively increase the content of monoamine neurotransmitters in children with cerebral palsy, enhance cerebral blood circulation, and reduce brain damage

摘要:
Cervical laminoplasty surgery is an alternative to laminectomy. It can increase the space of the spinal cord available by raising the lamina, and achieve the indirect decompression effect to treat cervical spondylosis. Various techniques of laminoplasty have since been developed after two prototype techniques: Hirabayashi’s open-door laminoplasty and Kurokawa’s double-door laminoplasty. Several studies report superior biomechanical stability of the cervical spine after laminoplasty compared with laminectomy. Recent development in laminoplasty is preservation of muscle attachment, which enabled dynamic and static stabilization of the cervical spine by neck extensor muscles. After treatment with new laminoplasty techniques with active postoperative neck muscle exercises, postoperative instability, kyphosis, axial neck pain, and loss of ROM become minimal. The development，complications and future trends of cervical laminoplasty are summarized below.

摘要:
Objective: To investigate the effects of gastrodin on neurotransmitter effect, stress response, blood vessel and nerve function in migraine patients. Methods: A total of 90 patients with migraine admitted to our hospital from September 2016 to December 2017 were randomly divided into observation group and control group with 45 cases in each group. The control group was treated with flunarizine hydrochloride, while the observation group was treated with gastrodin based on the control group. The levels of neurotransmitter effect[including 5-serotonin (5-HT) and tumor necrosis factor alpha (TNF-alpha)], stress response[oxidized low density lipoprotein (ox-LDL) and paraoxonase-1 (PON-1)], vascular function[including nitric oxide (NO), endothelin-1 (ET-1)] and neurological function[including high brain-derived neurotrophic factor (BDNF) and calcitonin gene-related peptide (CGRP)] related indexes were observed and compared between the two groups. Results: The two groups showed significant changes in transmitter effect, stress response, blood vessel and nerve function. Before treatment, there was no significant difference in the levels between the two groups. After treatment, the levels of TNF-a, ox-LDL, NO, ET-1, BDNF and CGRP in the two groups were significantly lower than those before treatment, while the levels of 5-HT and PON-1 were significantly higher than those before treatment. And after treatment, the levels of TNF-a, ox- LDL, NO, ET-1, BDNF and CGRP in the observation group were significantly lower than those in the control group, while the levels of 5-HT and PON-1 were significantly higher than those in the control group. Conclusions: Gastrodin treatment can regulate oxidative stress level and improve vascular and neurological function in migraine patients.

摘要:
Objective: To investigate the correlation between the change in expression of the tumor associated macrophage (TAM) markers CD68 and CD206 and the clinicopathological parameters. Methods: We retrospectively analyzed 28 PGI-DLBCL patients by immunohistochemical stainning. The surface expression of biomarkers CD68 and CD206 on TAMs in samples obtained at diagnosis was compared with that in specimens obtained at first relapse. Based on the change in expression levels of CD68 and CD206 from diagnosis to relapse, patients were categorized into three groups: “increased”, “stable” and “decreased”. Results: A significant difference was observed between the three groups with respect to CD68 and CD206 expressions (P=0.012) and there existed a consistency between the two (P=0.008). The three groups showed a negative correlation with age, sex, stage, B symptoms, diagnosis, ECOG performance status, and IPI scores, while a positive correlation was observed with the site of lesion of CD206 expression (P=0.032). The time to relapse (TTR) in the three groups of CD68 and CD206 was not significantly different (P=0.23, P=0.818). Conclusion: Our study suggests that increase in CD206 and decrease in CD68 expression at relapse indicates M1-TAM polarization into M2-TAM, which plays an important role in PGI-DLBCL relapse. Furthermore, M2-TAM polarization may be associated with the site of Primary gastric diffuse large B lymphoma.

Objective: To explore the effect of selenium supplementation on thyroid function, immune response and oxidative stress in HT patients with normal thyroid function. Methods: A total of 120 Hashimoto's thyroiditis patients with normal thyroid function admitted to our hospital from June 2016 to March 2018 were randomly divided into treatment group and control group with 60 cases in each group. The control group was given oral placebo, while the treatment group was given selenium yeast. The expression levels of thyroid function [including thyroid stimulating hormone (TSH), free triiodothyronine (FT3) and free thyroxine (FT4)], immune response [including thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TGAb), interferon-γ (IFN-γ), interleukin-4 (IL-4)] and oxidative stress [including malondialdehyde (MDA), glutathione peroxidase (GPx) and superoxide dismutase (SOD)] were observed and compared between the two groups. Results: The two groups showed significant changes in auxiliary diagnosis, immune response and oxidative stress. Before treatment, there was no significant difference in the levels between the two groups. After treatment, there was no significant difference in the above indexes between the control group and that before treatment. There was no significant difference in thyroid function related indexes between the treatment group and the control group. The levels of TPOAb, TGAb, IFN-γ and MDA in the treatment group were significantly lower than those before treatment and in the control group, while the levels of IL-4, GPx and SOD were significantly higher than those before treatment and in the control group. Conclusions: Selenium supplementation can stabilize thyroid function, reduce the level of thyroid antibody production, and improve immune response and oxidative stress response in HT patients.

摘要:
目的：探索海南番木瓜提取物对D‑半乳糖所致小鼠衰老模型的改善学习记忆障碍和抗衰老的作用。方法：将水迷宫实验筛选认知能力正常的4月龄昆明种小鼠共72只，根据随机平均原则，分为阴性对照组、模型组、吡拉西坦组以及海南番木瓜提取物高、中、低剂量组（400、200、100 mg/kg），共6组，每组12只，海南番木瓜提取物与吡拉西坦组每天以灌胃给药途径给予以上药物，阴性对照与模型两个组以同样的给药途径给予等量0.9% NaCl溶液。各组小鼠每周称重1次；给药的同时，每天用2% D‑半乳糖对除阴性对照组小鼠外各组小鼠进行腹腔注射，阴性对照组小鼠注射0.9% NaCl溶液，共7周。49 d后，通过Morris水迷宫观察小鼠的空间学习记忆能力；后取各组小鼠脑组织分别检测其超氧化物歧化酶（Superoxide Dismutase，SOD）、丙二醛（malondialdehyde，MDA）、过氧化氢酶（catalase，CAT）、一氧化氮合酶（Nitric oxide synthase，NOS）的含量；以HE染色法观察海马组织病理学的改变，Western blot测定脑组织核因子‑E2‑相关因子（Nrf2）蛋白表达水平。结果：海南番木瓜提取物干预衰老模型小鼠后，其高、中、低剂量组可不同程度地缩短小鼠的游泳时间和游泳距离，同时能升高小鼠脑组织SOD、CAT、NOS活力和降低MDA含量；且高剂量组表现最佳，优于吡拉西坦组（P<0.01）；同时能通过减少神经元细胞核固缩来改善小鼠海马组织中神经元组织病理学改变，并能呈剂量依赖性提高小鼠脑组织中Nrf2蛋白的表达。结论：海南番木瓜一定程度上有延缓D‑半乳糖所致亚急性衰老小鼠的各项体征，具有一定的抗衰老的作用，其作用可能与Nrf2信号通路有一定的联系。

摘要:
Objective: To systematically evaluate the effects of sleep status on renal function in patients with chronic kidney disease (CKD). Methods: To search the relevant literature related to the effects of sleep status on renal function of CKD patients on PubMed database, EMBase database, the Cochrane Library database, CNKI database, Chinese Biomedical Literature Database, VIP and Wanfang database from the initial to June 2018, all literature that met the criteria were included. According to the type of studies, the quality of the literature was evaluated by NOS scale in the cohort study and AHRQ scale in the cross-sectional study, and systematically evaluated the outcome indicators, the main outcome indicators were estimated glomerular filtration rate (eGFR) and endogenous creatinine clearance rate (Ccr), while the secondary indicators were Pittsburgh Sleep Quality Index (PSQI), Sleep Quality (SQ), Serum Creatinine (Scr), Hemoglobin (Hb), Albumin (ALB) and Urine Protein/Creatinine Ratio (UPCR). Results: Four literature and one meeting abstract were included in this study, of which four were cohort studies, three of them the NOS quality evaluations were high, one of them was medium, the remaining one was cross-sectional study, and the AHRQ quality evaluation was medium. This study shows that sleep status has a certain correlation with renal function. Shorter sleep time or poor sleep quality can lead to deterioration of renal function. Among them, the research data of Sabbatinit research team in Italy showed that Ccr gradually decreased with the increased of the PSQI; studies of Cohen research team and the Ricardo research team in the United States showed that eGFR decreased with the increased of the PSQI; the study of Kumar research team in the United States showed that the lower SQ , the worse renal function; the study of Knutson’ research team in British showed that the shorter sleep time, the lower eGFR. In addition, studies showed that sleep index also has influence on Hb, ALB, Scr, UPCR and other indicators. Conclusion: Sleep status can affect the renal function of CKD patients in different degrees. Shorter sleep time and poor sleep quality will damage renal function and accelerate the progress of CKD.

摘要:
Objective: To investigate the effect of dexmedetomidine against liver ischemia-reperfusion injury in rats by reducing endoplasmic reticulum stress. Methods: A total of 24 adult male Sprague-Dawley rats were randomly divided into sham operation group (6 rats, Sham group), liver ischemia-reperfusion injury group (6 rats, I/R group), and liver ischemia-reperfusion injury +dexmedetomidine pretreatment group (6 rats, I/R +Dex pretreatment group) (25 μg/kg intraperitoneally 30 min before ischemia), and liver ischemia-reperfusion injury +dexmedetomidine post-treatment group (6 rats, I/R +Dex post-treatment group) (25 μg/kg intraperitoneally 30 min after reperfusion). Hepatic ischemia-reperfusion injury model was performed by after clamping the hepatic hilum for 30 min and reperfusion for 6 h. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were measured by automatic biochemical analyzer. Malondialdehyde (MDA) and superoxide dismutase (SOD) activity were detected by enzyme-linked immunosorbent assay (ELISA). The pathological changes of each group were observed by HE staining. The expression of endoplasmic reticulum stress (P-PERK, P-IRE1α, CHOP) were detected by Western blot. Results: Compared with the Sham group, the serum levels of ALT and AST were significantly higher in the I/R group, compared with the I/R group, the serum ALT and AST in I/R+Dex pretreatment group and the I/R+Dex post-treatment group were significantly reduced; Compared with the Sham group, MDA activity in the liver tissue of the I/R group was significantly increased, while the SOD activity was significantly decreased, and the pathological score of the liver tissue was significantly increased; Compared with the I/R group, MDA activity and liver histopathology scores in I/R+Dex pretreatment group and the I/R+Dex post-treatment group were decreased, while SOD activity increased; The expression of P-PERK, P-IRE1α, CHOP in the I/R group were significantly higher than that in the Sham group, while the expression of the above indicators were reduced in I/R+Dex pretreatment group and the I/R+Dex post-treatment group. Conclusion: Dexmedetomidine can significantly attenuated liver ischemia-reperfusion injury in rats, which may be related to the reduction of endoplasmic reticulum stress.

摘要:
Objective: To explore the best time for progesterone supplementation in AID ovulation induction cycles by Letrozole. Methods: The data analysed in this study were collected from 509 patients who were performed AID (Artificial Insemination by Donor) administrated letrozole (LE) between 2014.8-2015.7. All patients were randomly divided into 4 groups by the time of progesterone administrated, including experimental group and the control group. The experimental group was divided into group 1-72 h after ovulation, group 2-48 h after ovulation, group 3-24 h after ovulation and control group—without administrated LE. The gestation and live birth rate were evaluated by monitoring vaginal ultrasound and HCG blood value 14 d after AID. Results: The pregnancy rate with administrated progesterone added 72 h after ovulation was 31.9%, which was significantly higher than those of other groups, the same situation as groups added progesterone was significantly higher than the control group. However, there was no significant difference in the numbers of abortions among the four groups. The LBR of group 4 was significantly lower than that of group 1. Conclutions: Progesterone administrated 72 h after ovulation can promoted the gestation rate, but did not affect the rate of miscarrage .
