Objective To systematically assess the efficacy and safety of acupuncture in treating type 2 diabetes.Methods Related literature was retrieved with a computer. After the data were sifted out from the literature according to the established criteria, they were collected and crossly checked by two researchers independently. The data were input to RevMan5.2 for statistical analysis. Results A total of ten studies were included with a total of 743 patients. The results of Meta analysis showed 1) Post-treatment total efficacy rate was higher in the acupuncture or combined acupuncture and medicine group than in the control group [OR=3.60, 95%CI (2.11,6.13)] and there was a statistically significant difference (Z=4.71,P<0.00001); 2) Post-treatment range of decrease in fasting blood glucose (FBG) was significantly higher in the experiment group than in the control group [WMD=-1.20,95%CI (-1.38,-1.02)] and there was a statistically significant difference (Z=12.88,P<0.00001); 3) Post-treatment range of decrease in 2-h postprandial blood glucose (2hPBG) was significantly higher in the experiment group than in the control group [WMD=-1.27, 95%CI (-1.47,-1.06)] and there was a statistically significant difference (Z=12.02,P<0.00001).Conclusion Clinically acupuncture or combined acupuncture and medicine is more effective than Chinese herbal medicine or Western medication alone in treating T2DM and has no toxic and side effects.

Objective To compare the pathogenicity between Ureaplasma urealyticum serotype 1 (Up1)and 8 (Uu8) in the genital tract of BALB/c mice.Methods A total of 48 BALB/c mice were randomly and equally divided into four groups:blank control group receiving no treatment,estradiol group pretreated with intramuscular injection of estradiol followed by intravaginal inoculation with sterial liquid culture media,Up1 and Uu8 groups pretreated with intramuscular injection of estradiol followed by intravaginal inoculation with suspensions of Up1 and Uu8 respectively.Three mice were randomly selected from each group to be sacrificed after the collection of vaginal lavage fluid on day 3,7,14 and 21 after the inoculation.Vaginal and uterine tissue specimens were obtained from these sacrificed mice and underwent hematoxylin and eosin (HE) staining.Vaginal lavage fluid samples were subjected to culture of Uu and measurement of tumor necrosis factor-α (TNF-α).Results No evidences were observed for Uu growth in either the blank control group or estradiol group at any of the time points after the inoculation,with the average level of TNF-α in vaginal lavage fluid being (4.17 ± 0.85) pg/ml at these time points in both groups.Uu grew in all the vaginal lavage fluid samples from the Up1 and Uu8 groups at the four time points,with the color change unit (CCU) value decreasing with time.The level of TNF-α in vaginal lavage fluid peaked on day 14 after the inoculation in the Up 1 ((14.93 ± 1.11) pg/ml) and Uu8 ((27.04 ± 24.26) pg/ml) groups.Both Up1 and Uu8 infection caused acute and chronic inflammatory responses in the mice,which were mainly located in the uterus,and Up1 might cause intrauterine adhesion.Conclusions At the same inoculation concentration,no significant difference is found in the pathogenicity between Up1 and Uu8,both of which appear to mainly cause cervicitis.Upl might be partially responsible for intrauterine adhesion in mice.

OBJECTIVETo explore attenuation and mechanism of endoplasmic reticulum stress (ERS)-mediated hepatocyte apoptosis in rats with alcohol-induced liver injury by Qinggan Huoxue Recipe (QGHXR) and its disassembled formulas (Qinggan Recipe and Huoxue Recipe respectively).
METHODSA rat model of chronic alcoholic liver injury was successfully established using a compound reagent of alcohol, corn oil, and pyrazol. The modeled rats were randomly divided into the model group, the QGHXR group, the Qinggan Recipe (QGR) group, and the Huoxue Recipe group (HXR). The CCl4 control group and the normal control group were also set up. There were ten rats in each group. All rats of modeled groups were gastrogavaged with alcohol compound reagent every morning. Rats in the QGHXR group (at the daily dose of 9. 5 g/kg, QGR group (at the daily dose of 3.0 g/kg), and HXR group (at the daily dose of 6.5 g/kg) were administered with corresponding medicines by gastrogavage every afternoon. Equal volume of normal saline was given to rats of the model group by gastrogavage. CCl4 was intraperitoneally injected at the dose of 0.3 mL/kg to rats in the CCl4 control group, once per week. Normal saline was given to rats in the normal control group by gastrogavage. The treatment was lasted for two weeks. Pathological changes of the liver were observed by histopathology. Serum total homocysteine (tHCY) level was detected by ELISA. The hepatocyte apoptosis rate was detected using flow cytometry. The gene and protein expressions of eukaryotic translation initiation factor 2 alpha (elF-2alpha), phosphorylation elF-2alpha (pelF-2alpha), glucose-regulated protein 78 (GRP78), and Caspase-3 in the liver were examined using Real-time PCR and Westen blot respectively.
RESULTSCompared with the normal control group, typical pathological changes of chronic alcoholic liver injury such as steatosis, inflammation, and even fibrosis occurred in model rats. The hepatocyte apoptosis obviously increased, with the apoptosis rate reaching the five-fold of that in normal rats. Besides, early apoptosis dominated. The serum tHCY level significantly increased. The expressions of p-elF-2alpha, GRP78, and Caspase-3 protein obviously increased (P < 0.01). Expressions of GRP78 and Caspase-3 mRNA significantly increased (P < 0.05, P < 0.01). Compared with the model group, the degrees of the liver injury and the hepatocyte apoptosis in the QGHXR group, the QGR group, and the HXR group were significantly alleviated. The serum tHCY level was significantly lowered. The protein expressions of p-elF-2a, GRP78, and Caspase-3 obviously decreased (P < 0.01). mRNA expressions of GRP78 and Caspase-3 obviously decreased in the QGHXR group (P < 0.05, P < 0.01). Only GRP78 mRNA expression obviously decreased in the QGR group (P < 0.05).
CONCLUSIONQGHXR and its disassembled formulas could attenuate ERS-mediated hepatocyte apoptosis in alcohol-induced liver injury rats by lowering the serum tHCY level and expressions of ERS apoptosis correlated factors.

Objective To investigate the current situation and variation in the tendency of Kaschin-Beck disease (KBD) in Shanxi province, to assess the effectiveness of prevention measures, and to provide evidence for making scientific and effective tactics in prevention and control of the disease. Methods In 2008, according to "The National Technical Scheme for Kaschin-Beck Disease Control in 2007", children aged 7 - 12 years underwent clinical and X-ray examination in two historical severe KBD areas of Shanxi province, the observed position on Xray film was finger bone and carpal bone. Adults aged 16 years and above were clinically examined in 50 villages of 13 counties of KBD areas, Shanxi province. The diagnosis was based on "Diagnostic Standard of Kashin-Beck Disease"(GB 16003-1995), the adult patients were degreed according to the state of illness and divided into different groups according to their ages. Results A total of 181 children were examined, none of them was diagnosed as clinical KBD patient. The positive cases of X-ray were 2, X-ray detectable rate of metaphysis was 1.1% for children.In the 50 villages 13 871 of adults were examined and 801 KBD patients were found and the detectable rate was 5.77%. The detectable rate increased with age. The adult patients distributed mainly in the subpopulation aged 51years and above and these patients accounted for 70.66% (566/801) of total people examined. Degrees Ⅱ and Ⅲ patients at these ages accounted for 71.78%(206/287) of total degrees Ⅱ and Ⅲ patients. Conclusions The state of child KBD in Shanxi is under the national control standards. The detectable rate of adult KBD is higher. Relevant departments should pay close attention to the treatment of adult patients.

OBJECTIVESTo investigate the role of Undecanoate (Andriol), as a kind of testosterone, in regulating the relaxation of isolated rat corpus cavernosum in vitro.
METHODSThe castrated rats were given high and low dosage Andriol respectively, compared with intact and castrated rats. After treatment of 4 weeks, the corpora cavernosa were cut, trimmed as to strips. Norepinephrine(NE) was added to contract each of the tissue strips. Next, sodium nitroprusside(SNP), electric functional stimulation(EFS) were used to relax the strips. Percent relaxations were examined.
RESULTSHigh-dose Andriol(20 mg/kg) was significantly effective to castrated rats on percent relaxation induced by 10(-3) mol/L SNP and EFS. Low-dose Andriol(10 mg/kg) was also effective to relax strips induced by 10(-3) mol/L SNP. According to statistics, the differences were significant (P < 0.01).
CONCLUSIONSThe percent relaxations of castrated rats were increased after taking Andriol, and it could increase the relaxation of corpara cavernosa.
