Objective:To systematically evaluate the therapeutic efficacy of tuina therapy for primary insomnia.Methods:Nine Chinese and English databases were searched from the inception to May 2017 to identify randomized controlled trials (RCTs) studying tuina therapy for insomnia.The enrolled articles were all RCTs with tuina as the monotherapy or major therapy in the experiment group,with clear diagnostic criteria for primary insomnia well recognized worldwide or in China,and Pittsburgh sleep quality index (PSQ I) as one of the outcome measures.Two researchers evaluated the risk of bias and quality of the enrolled studies by following Cochrane Handbook version 5.1.0.The meta-analysis was performed by RevMan version 5.3.Results:Eleven studies were included with a total of 1 076 participants.The Western medication adopted in the control groups were benzodiazepine receptor agonists.The studies were all assessed as high risk of bias for blinding since blinding method was unable to be performed due to the specificity of tuina therapy;no study reported the support of fund or potential interest conflict,so they were all rated unclear for selective reporting.The meta-analysis showed that compared with other traditional Chinese medicine therapies,tuina worked more effectively in reducing the PSQI score (MD=-4.11<0,95% confidence interval (CI)-6.01 to-2.22,P<0.0001);compared with oral administration of Western medication,tuina showed more significant efficacy in reducing the PSQI score (MD=-3.42<0,95%CI-5.19 to-1.66,P<0.0001).Subgroup analysis showed that head tuina alone showed no significant difference compared with oral administration of Western medication regarding the change of PSQI score (MD=-4.19<0,95%CI-8.87 to 0.50,P>0.05);a combination of head and back tuina could more effectively reduce the PSQI score compared with oral administration of Western medication (MD=-2.08<0,95%CI-3.09 to-1.06,P<0.0001).Conclusion:Tuina can produce more significant efficacy in treating primary insomnia compared with other traditional Chinese medicine therapies and oral administration of Western medication,especially the combination of head and back tuina.

OBJECTIVETo investigate the effects of hydroxycamptothecin (HCPT) on proliferation and apoptosis of rat hepatic stellate cells (HSC).
METHODSRat HSC line (HSC-T6) and rat hepatocyte line (BRL-3A) were treated with different concentrations of HCPT (0, 0.008, 0.016, 0.031, 0.125, 0.25, 0.5, 1, 2, 4, 8, 16, 32 mg/L respectively) for 24 h. Cell proliferation was assessed by MTT colorimetric assay, apoptosis was detected with PI staging followed by flow cytometry, and by DNA ladder assay. The morphological change of apoptosis was observed under transmission electron microscopy (TEM).
RESULTSMTT assay indicated that HCPT significantly inhibited the proliferation of HSC-T6 and BRL-3A in a dose-dependent manner. 24 h after the treatment with different concentrations of HCPT (0.25, 0.5, 1 mg/L), the apoptosis rate (13.46%+/-2.42%, 26.25%+/-5.65%, 47.05%+/-8.76%, respectively) in HSC-T6 was significantly higher than that in control cells (4.89%+/-1.80%, F = 34.24, P less than 0.01). 24 h after 0.5 mg/L HCPT treatment, cell shrinkage, nucleoli disappearance, chromatin condensation were found under TEM, and DNA ladder was demonstrated by agarose gel electrophoresis.
CONCLUSIONHCPT could significantly inhibit proliferation and induce apoptosis of HSC-T6 in a dose-dependent manner.

OBJECTIVETo conduct a meta-analysis on the effects of testosterone on the related factors of metabolic syndrome in hypogonadal males.
METHODSBased on the principles and methods of Cochrane systematic reviews, we searched the PubMed (1980 to August 2009), Embase (1980 to August 2009), the Cochrane Central Register of Controlled Trials and CNKI (1995 to August 2009) , and handsearched some relevant journals and conference proceedings as well. We also identified randomized controlled trials addressing the use of testosterone for the treatment of hypogonadism, screened the retrieved studies according to the predefined inclusion and exclusion criteria, evaluated the quality of the included studies, and performed a meta-analysis on the results of homogeneous studies using the Cochrane Collaboration's RevMan 5.0 software.
RESULTSSix randomized controlled trials were included. The results of analysis indicated that testosterone substitution could significantly ameliorate fasting blood glucose, total cholesterol and insulin resistance in hypogonadism patients, and it could also reduce LDL, HDL, triglyceride and systolic blood pressure, though with no significant difference from the controls. However, there was insufficient evidence to show the effects of testosterone on waist circumference, waist-hip ratio and diastolic blood pressure.
CONCLUSIONExisting clinical evidence has demonstrated the positive effects of testosterone substitution on the improvement of insulin resistance, blood glucose and lipids, but due to the heterogeneity and high risk of bias in the included studies, the evidence might be insufficient to give full support to the demonstration. Further large-scale trials are required to define the metabolic effects of testosterone in the treatment of hypogonadism.

OBJECTIVETo study the association between the polymorphism of human monoamine oxidase type A (MAO-A) gene and Parkinson's disease(PD).
METHODSFnu4HI restriction fragment length polymorphism(RFLP) and PCR-RFLP were used to detect the mutation of MAO-A gene. The frequencies of alleles and genotypes at the MAO-A Fnu4HI locus on the X chromosome in different PD group were compared with those of the control group.
RESULTSIt was found that the frequencies of G allele in the patients with PD and controls were 0.613 and 0.527 respectively, P=0.039 "the frequencies of TT genotype were 0.303 and 0.415(P=0.014), and the frequencies of GG genotype were 0.564 and 0.451 respectively(P=0.021). When the patients were divided into two groups by age-onset, significant difference in the allelic and genotypic frequencies was observed only between early-onset PD group and control group. And when the PD patients were grouped by sex, significant difference was observed only between male PD group and male control group (the frequencies of G allele being 0.669 and 0.500 respectively, P=0.005).
CONCLUSIONThis study revealed significant differences between PD group and control group in allelic and genotypic frequencies. The findings supported the hypothesis about an association between MAO-A gene and PD, suggesting that age at onset of PD and gender predisposition might be related to the putative association, and Fnu4HI SNP be a risk factor for PD.

OBJECTIVETo evaluate the long-term effects of delayed hyperbaric oxygen (HBO) therapy on neonatal rats with hypoxic-ischemic brain injury (HIBD).
METHODPostnatal 7 days newborn rats (n = 52) were randomly set to three groups: control (n = 18, sham operation), HIBD (n = 17), or HBO (n = 17). Pups in the HBO group were subjected to hyperbaric oxygen treatment with 2 atmosphaera absolutus, 5 x 30 min at a 24 h intervals since 48-72 h after the HIBD model. All the animals were tested for the spatial learning and memory ability in the Morris water maze from postnatal days 37 to 41. At day-42, rats were decapitated and the brains were analyzed for morphological and histological changes, including brain shapes and weights, survival neurons, percentage of AchE positive area and NOS positive neurons in hippocampal CA1 region.
RESULTSRats in HBO and HIBD groups displayed significant morphological and histological damages, as well as severe spatial learning and memory disability. The average escape latency of Morris water maze in HBO group [(56 +/- 23) s] and HIBD group [(56 +/- 22) s] were longer than the control [(23 +/- 16) s] (P < 0.05). The swimming time in HBO group [(30 +/- 5) s] and HIBD group [(29 +/- 6) s] were shorter than the control [(51 +/- 5) s] (P < 0.05). The swimming length in HBO group [(572 +/- 92) cm] and HIBD group [(548 +/- 92) cm] were shorter than the control [(989 +/- 101) cm] (P < 0.05). The weight of left brains in HBO group [(598 +/- 46) mg] and HIBD group [(601 +/- 59) mg] were lighter than the control [(984 +/- 18) mg] (P < 0.05). The survival neurons of hippocamal CA1 region in HBO group [(97 +/- 27)/mm] and HIBD group [(100 +/- 27)/mm] were less than the control [(183 +/- 8)/mm] (P < 0.05). The percentage of AchE-positive fibers in HBO group [(18.4 +/- 2.2)%] and HIBD group [(18.5 +/- 2.2)%] were less than the control [(27.5 +/- 2.2)%,] (P < 0.05). NOS-positive neurons in HBO group [(21 +/- 5)/mm(2)] and HIBD group [(19 +/- 4)/mm(2)] were also less than the control [(34 +/- 6)/mm(2)] (P < 0.05).
CONCLUSIONDelayed HBO therapy resulted in no protection against either HIBD-induced brain morphological and histological deficits or spatial learning and memory disability.
