Objective: To evaluate the efficacy and safety of acupuncture for the treatment of knee osteoarthritis and to provide evidence for its use in clinical practice. Methods: Eight databases were extensively searched up to March 2018. Randomized controlled trials (RCTs) comparing the efficacy of acupuncture with sham acupuncture or no acupuncture for knee osteoarthritis were included. Study selection, data extraction and quality assessment were independently conducted by two reviewers. The Cochrane Collaboration's tool was used for assessing the risk of bias. Results: A total of 18 RCTs were included, involving a total of 3522 participants. The results showed that acupuncture was superior to sham acupuncture in relieving pain (SMD=-0.34, 95％CI:-0.57 to -0.11, I2=85％, P=0.003) and improving physical function (SMD=-0.34, 95％CI: -0.57 to -0.11, I2=85％, P=0.003). In comparison to the no-acupuncture group, the acupuncture group also showed significant advantages in relieving pain (SMD=-0.79, 95％CI: -1.15 to -0.43, I2=87％, P<0.0001) and improving physical function (SMD=-0.75, 95％CI:-1.19 to -0.31, I2=91％, P=0.0008). Sensitivity analyses suggested that the results were robust, and Egger's test found no potential publication bias. Conclusion: In the treatment of knee osteoarthritis, the acupuncture group had significant advantages over sham acupuncture or no-acupuncture groups in relieving pain and improving physical function.

Blood-brain barrier (BBB) injury is an important pathological change of ischemic stroke.Occludin constitutes the major component of the tight junction of BBB, which plays a significant role in maintaining the BBB integrity.Cerebral ischemia initiates occludin degradation through the induction of the activation of inflammatory mediators, reactive oxygen, and matrix metalloproteinases, and causes the changes of tight junction cytoskeletal protein interaction, resulting in BBB integrity destruction and increased permeability.This article mainly elaborates the relationships of occludin with BBB, brain edema and hemorrhagic transformation, as well as the possibility of occludin as an intervention target for ischemic stroke.

Hemorrhagic transformation(HT) is the most severe complication after tissue-type plasminogen activator (tPA) thrombolysis. It greatly limits the clinical application of tPA. Early blood-brain barrier ( BBB) damage may be an important mechanism for HT. Maintaining the integrity of BBB can significantly decrease the risk of HT. This article review s the roles, mechanisms, and preventive measure of early BBB damage in HT after tPA thrombolysis.

BACKGROUND: Microarc oxidation (MAO) is a break-through anodyzing technology for forming oxide films on valve metal.Use of this technology allows thick, porous oxide layers to be formed on the surface of pure titanium. Few biocompatibility reports using this treatment have been found.OBJECTIVE: The blood compatibility of a novel surface modified titanium substrata biomaterial using MAO was investigated.DESIGN: Positive and negative control, contrast observation and gold standard control.SETTING: Wuhan Union Hospital.MATERIALS: A healthy male adult New-Zealand rabbit, weighing 2.5 kg and ordinary grade, was selected in this study.Pure titanium sticks TA1 (Baoji Yingnaite Non-ferrous Metal Co., Ltd.), MAO-Ti and 20 g/L potassium oxalate were also selected in this study.METHODS: The study was carried out in the Laboratory of General Surgery, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology in May 2006. ① Materials: Titanium substrate of 10 mm in diameter and 2 mm in depth was put in an electrolyte which was quipped with deionized water, dibasic sodium phosphate, and ethanoic acid calcium for MAO treatment for 10 minutes. ② Groups: Three groups were analysed: test group, negative control group and positive control group. Test group: MAO-Ti was dipped in 10 mL saline; Positive control group: 10 mL deionized water was added in each tube; Negative control group: 10 mL saline was added in each tube. ③ Operation: Fresh whole blood was collected from rabbit and then mixed with the liquids in the three groups respectively after anti-coagulation. In addition, UV-Visible Spectrophotometer was used to evaluate the hemolytic ratio. A hemolytic ratio below or equal to 5% indicated that this novel material fitted the requirements. On the contrary, a hemolytic ratio higher than 5% proofed the existence of a hemolyzation.MAIN OUTCOME MEASURES: The hemolytic ratio of materials in three groups.RESULTS: The hemolytic ratio of the test group was 0.90%. The result indicated that this new material had no haemolysis effect.CONCLUSION: The material does not resolve red blood cells and is coincident with the international and governmental standard.

OBJECTIVETo observe the dose-effect relationship of electroacupuncture of different current intensities combined with Morphine of different dosage on alleviating the rats' tibial cancer pain, and explore the possible mechanism, which could provide the experiment basis for alleviating the tibial cancer pain by electroacupuncture combined with Morphine.

METHODSOne hundred female Wistar rats were randomly divided into a normal group, a model group and eight treatment groups, 10 cases in each group. The rats in the treatment groups were treated by combined therapies of electroacupuncture of different intensities with 2 Hz /100 Hz dense-disperse wave on "Jiaji"(EX-B 2)and different dosage Morphine in 2 factor 3 level conditions, once a day for 6 days. The pain thresholds were observed before the treatment and 0 min, 1 h, 2 h and 5 h after the first treatment as well as after 3 and 6 times of treatments. The glial fibrillary acidic protein (GFAP) expression was determined by immunohistochemical method.

RESULTSThe rats' pain thresholds were significantly increased with electroacupuncture of 2 mA and 1 mA (all P < 0.01) on the 0 min, 1 h and 2 h of the first treatment, between which there were no significant differences (all P > 0.05). The pain threshold was still increased by electroacupuncture of 2 mA on the 5 h of the treatment (P < 0.01), while that of 1 mA failed to take effect (P > 0.05). After 3 and 6 times of treatments, both electroacupuncture of 2 mA and 1 mA had the effect of increasing the pain threshold (all P < 0.01), and the effect of 2 mA was superior to that of 1 mA (P < 0.05), had the synergistic effect with 5 mg/(kg x d) Morphine (P < 0.05). After 6 times of treatments, both electroacupuncture of 2 mA and 1 mA could inhibit the expression of GFAP (both P < 0.01), and there was no significant difference between them (P > 0.05). Both of 5 mg/(kg x d) and 2.5 mg/(kg x d) of Morphine, however, didn't bring about inhibition effect (P > 0.05).

CONCLUSIONThere is a does-effect relationship on electroacupuncture of different current intensity for alleviating the tibial cancer pain in rats. The electroacupuncture with 2 mA, which is better than that with 1 mA, has the synergistic effect with 5 mg/(kg x d) of Morphine. The electroacupuncture can inhibit the expression of GFAP to cooperate with Morphine for the purpose of alleviating the rats' tibial cancer pain.

The total efficacy rate was 96.7% in the treatment group and 86.7% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Electroacupuncture at Huatuo jiaji points has a promoting effect on the rehabilitation of limb function in the flaccid paralysis stage of stroke.

Objective:To analyze the structure modes of general practice teams in community health care cen-ters in order to provide empirical evidence for the transformation of the community health service mode. Method:Pur-posive sampling was adopted. Twelve community health service centers in Beijing, Shanghai, Zhengzhou and Cheng-du, where the transformation of the community health service mode was piloted earlier and representative, were se-lected as the field survey sites. The qualitative method was used to collect the data accompanied by the quantitative method. Results:The structure models of general practice teams could be divided into four types:1) general practi-tioner+nurse+nurse assistant+pharmacist, 2) physician (general practitioner, herbalist physician) +nurse+com-munity volunteers, 3 ) physician ( general practitioner/herbalist physician ) +nurse +assistant +community volun-teers, and 4) general practitioner+nurse+assisting team (professionals of public health and maternal care, etc) +supportive team ( pharmacists, health technician, etc) . Conclusion:The paper verified the common sense conclusion that general practitioners should play an essential role in general practice teamwork. The four general practice team models analyzed above positively contributed to the improvement of efficiency and quality, the relationship between health professionals and patients, the promotion of community participation, and the combination between preventive care and clinical care.

Objective To investigate the effect of highly expressed β-catenin on the proliferative activity of and expressions of two apoptosis-related genes Bcl-2 and Bax by human skin fibroblasts induced by hydrogen peroxide (H2O2).Methods Normal human skin fibroblasts (HSFs) from child foreskin were divided into three groups:empty vector group transfected with the empty vector pcDNA3.1,H2O2 group transfected with the empty vector pcDNA3.1 followed by treatment with H2O2 (150 μ mol/L) for 2 hours,β-catenin group transfected with pcDNA3.1-β-catenin followed by treatment with H2O2 (150 μ mol/L) for 2 hours.Subsequently,methyl thiazolyl tetrazolium (MTT) assay was conducted to estimate proliferative activity of fibroblasts,flow cytometry to detect cell apoptosis,and reverse transcription (RT)-PCR and Western blot were performed to measure the mRNA and protein expressions of Bcl-2 and Bax respectively.The relative expression levels of genes were expressed as the ratios between the targets and GAPDH.Results Significant differences were found between the empty vector group,H2O2 group and β-catenin group in cellular proliferative activity (expressed as absorbance value at 570 nm:0.792 ± 0.012 vs.0.462 ± 0.012 vs.0.521 ± 0.015,P＜ 0.01) and apoptosis rate (3.407％ ± 0.217％ vs.24.555％ ± 1.793％ vs.15.360％ ± 0.755％,P＜ 0.01).Both mRNA and protein expression levels of Bcl-2 were significantly lower in the H2O2 group (0.333 ± 0.003 and 0.336 ± 0.004 respectively) than in the empty vector group (0.507 ± 0.013 and 0.514 ± 0.021,respectively,both P ＜ 0.01) and β-catenin group (0.404 ± 0.006 and 0.411 ± 0.005,respectively,both P ＜ 0.01).Increased expression levels of Bax mRNA and protein were observed in the H2O2 group compared with the empty vector group and β-catenin group (mRNA:0.451 ± 0.002 vs.0.303 ± 0.005 and 0.339 ± 0.012,protein:0.460 ± 0.008 vs.0.320 ± 0.013 and 0.346 ± 0.013,all P＜ 0.01).Conclusion High expression of β-catenin can raise proliferative activity of aging HSFs.
