Mitochondrial dysfunction has been implicated in the aetiology of sporadic Parkinson's disease but its role in the disease mechanism remains unclear.To investigate the effect of synuclein on mitochondrial dysfunction induced by rotenone.The human dopaminergic SH-SY5Y cells were used as a cell model.The cells over-expressed the wild-type ?-synuclein were treated with complex I inhibitor rotenone.The cell viability,complex I activity,Mitochondrial swelling and O2-content were tested at different time point-1w,2w,4w after rotenone treated.CCK-8 test results showed that the cell viability of overexpressed ?-synuclein(SH-SY5Y-Syn)was much lower than the control group(SH-SY5Y-Ctr).After administrating with rotenone about 1w or 2w the cell viability of SH-SY5Y-Syn became higher than that of SH-SY5Y-Ctr.On the 4th week the results were contrary to the first 2 weeks.Similar results were got when test the mitochondrial function.In the first 2 weeks after roteoone administrating,the mitochondrial function of SH-SY5Y-Syn was better than that of SH-SY5Y-Ctr.This suggest that the ?-synuclein could protect the mitochondrial against the injury induced by rotenone in the early stage-1w,2w,while this effect disappeared in the final stage-4w.

Rotavirus capsid protein Vp4 plays an important role in the virus adhering and entering the cells. In this study, a Vp4 gene cloned from a rotavirus strain TB-Chen was highly expressed in E.coli BL21 (DE3). The results of the Western blot showed that the protein possesses specific immuno-reactivities and can be specifically recognized by guinea pig antibodies against rotavirus strain SA11 or Wa. Some Vp4 dimers were formed during renaturation. These data obtained from this study provide a strong basis for further study on the structure and function of the Vp4.

OBJECTIVETo systematically evaluate acupuncture as a treatment for male infertility.

METHODSWe searched Chi na Biology Medical Database (CBM), Wan Fang Medical Information System, China National Knowledge Infrastructure (CNKI), VIP Information Resource System (VIP), and PubMed for published literature on acupuncture as a treatment for male infertility on May 1 2014. Based on the Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA), we evaluated the quality of the reports, conducted meta-analysis on the identified studies via RevMan5.2, and assessed the quality of the evidence in the literature by Grading of Recommendations Assessment, Development, and Evaluation (GRADE).

RESULTSA total of 12 studies involving 2,177 patients were included, the quality of which was evaluated as mediocre. With regard to the cure rate, acupuncture was comparable to traditional Chinese medicine (TCM) (P > 0.05) but better than Western medicine (RR = 4.00, 95% CI 1.63 to 9.82, P < 0.01) while acupuncture + TCM was better than either TCM (RR = 1.77, 95% CI 1.20 to 2.60, P < 0.01) or Western medicine used alone (RR = 2.73, 95% CI 1.51 to 4.93, P < 0.01), and acupuncture + Western medicine was better than Western medicine alone (RR = 1.88, 95% CI 1.17 to 3.02, P = 0.01). The combined use of acupuncture, ear pressure, TCM, and Western medicine showed a higher cure rate than the combination of TCM and Western medicine (RR = 3.45, 95% CI 2.90 to 4.11, P < 0.01). In therapeutic effectiveness, acupuncture was comparable to TCM (P > 0.05) but superior to Western medicine (RR = 1.41, 95% CI 1.12 to 1.71, P < 0.01), acupuncture + TCM was superior to either TCM (RR = 1.14, 95% CI 1.05 to 1.23, P < 0.01) or Western medicine alone (RR = 1.43, 95% CI 1.22 to 1.67, P < 0.01), and acupuncture + Western medicine was superior to Western medicine alone (RR = 1.25, 95% CI 1.05 to 1.49, P = 0.01). In improving sperm concentration, acupuncture was as effective as TCM (P > 0.05) and sham acupuncture (P > 0.05) but outdid Western medicine (RR = 27.00, 95% CI 24.27 to 29.73, P < 0.01) and acupuncture + TCM outdid either TCM (RR = 14.65, 95% CI 7.58 to 21.72, P < 0.01) or Western medicine alone (RR = 1.04, 95% CI--1.43 to 3.51, P > 0.05). In improving grade a sperm, acupuncture exhibited a similar effect to TCM (P > 0.05) and sham acupuncture (P > 0.05), and acupuncture + TCM was more effective than TCM alone (RR = 7.78, 95% CI 3.51 to 12.23, P < 0.01) but equally effective as Western medicine (P > 0.05). In elevating the level of grade a + b sperm, acupuncture + TCM excelled either TCM (RR = 11.00, 95%, CI 3.17 to 18.82, P < 0.01) or Western medicine alone (RR = 12.22, 95% CI 6.87 to 17.57, P < 0. 01), while acupuncture produced a comparable effect with sham acupuncture (P > 0.05). As for the quality of the included studies, only 3 conclusions of the 23 meta-analyses were assessed to be of average quality, while the others of poor or extremely poor quality. Therefore, the recommendation grade of the conclusions was low.

CONCLUSIONFor the treatment of male infertility, acupuncture is reported to be equally effective as TMC and more effective than Western medicine, and its effectiveness is enhanced when applied in combination with either TCM or Western medicine. Acupuncture is distinctively efficacious in improving sperm quality. Nevertheless, the overall quality of the included studies is low.

OBJECTIVETo explore the relationship of bacteria identified in cholesterol gallstones and gallstone formation.

METHODSObserve the bacteria activity in model bile and the influence of bacteria on the cholesterol nucleation time (NT).

RESULTS(1) Model bile were suitable for the growth of E. coli, Pseudomonas aeruginosa, staphylococcus aureus, enterococcus faecalis, clostridium difficile and Clostridium. Propionibacterium acne grew weakly and the growth of Bacteroides fragilis was restrained in model bile. (2) Only pseudomonas aeruginosa and enTerococcus faecalis could ly shorten the cholesterol nucleation time. (3) With pseudomonas aeruginosa or enTerococcus faecalis added in model bile, the formation of cholesterol crystals presented a progressive course of evolution.

CONCLUSIONSPseudomonas aeruginosa and enterococcus faecalis, not propionibacterium acne, have pro-nucleating ability in model bile.

OBJECTIVETo explore the relation of angiotensin-converting enzyme (ACE) gene polymorphism, angiotensin II type I receptor (ATIR) gene polymorphism and other factors on cerebral infarction.

METHODSOne thousand three hundred fifty-one subjects from Tangshan coalmine were enrolled with study method of cluster sampling. Face to face interviews were conducted to fill in questionnaires by trained interviewers. ACE gene, ATIR gene and inflammation factors including tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), IL-8, IL-10, C reactive protein (CRP), fibrinogen (Fg), fibrin monome polymerized velocity (FMPV), absorbance maximum (A(max)), FMPV/A(max), were measured.

RESULTSNo different prevalence rates of ACE genotype were found on cerebral infarction. The distributions of AA genotype of ATIR gene in the cerebral infarction was higher than that of the controls. The prevalence of AA genotype was higher than other groups, but the prevalence of combined genotype did not show much difference. Under the existence of factors that related to cerebral infarction, AA genotype frequencies were higher than those of non-smoking and with hypertension. IL-6, ATIR gene polymorphism, sex, FMPV/A(max) were strongly related to cerebral infarction. The level of IL-6 was higher than the normal ones.

CONCLUSIONSThe prevalence of cerebral infarction obviously increased in the hypertensive groups having AA genotype of ATIR gene. In the cerebral infarction groups, the level of IL-6 was higher than that in the normal population, indicating that these can be resulted from local inflammation and immunity reactivity. Environmental and genetic factors in the pathogenesis of cerebral infarction might have coordinating functions.
