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 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 detect the putative association between the polymorphism of human NAD(P)H: quinone oxidoreductase (NQO1) gene and Parkinson's disease(PD).
METHODSPolymerase chain reaction-denaturing high performance liquid chromatography (PCR-DHPLC) was used to detect the polymorphism of monoamine NQO1 gene cDNA 609 site(C-->T). The frequencies of alleles and genotypes in different PD groups were compared with those of the control group.
RESULTSIt was found that the frequencies of TT genotype in the patients with PD and in the controls were 0.226 and 0.118 respectively (P=0.004), i.e., TT genotype increased the risk of PD by 2.186-fold (P=0.005). When the patients with PD were divided into two groups by the age at onset, significant difference in the genotypic frequencies was observed only between late-onset PD group and control group (the frequencies of TT genotype being 0.260 and 0.118, P=0.001) and TT genotype increased the risk of late-onset PD by 2.627-fold(P=0.001). There were no significant differences in frequencies of alleles between different PD groups and control group.
CONCLUSIONThis study revealed significant differences in genotypic frequencies between PD group and control group. The findings supported the hypothesis about an association between NQO1 gene and PD, suggesting that the age at onset of PD might be related to the putative association, and NQO1 cDNA C609T site be a risk factor for PD.

OBJECTIVETo evaluate the value of multi-spiral CT thinner scanning and three-dimensional and multi-planar reconstruction in the diagnosis of atlantoaxial fracture and dislocation.
METHODSSixty-nine patients suffered from atlantoaxial injuries included 54 males and 15 females with an average age of 46.5 years ranging from 17 to 73. Roentgenograph, multi-spiral CT thinner scanning, three dimensional reconstruction (3D) and multi-planar reconstruction (MPR) were applied for patients before and after surgery.
RESULTSMulti-spiral CT thinner scanning and reconstruction provided clear images for all subjects. There were 49 odontoid bone fractures (Anderson type II 35, type III 14), 9 cases combined injuries of C1 and C2 (Jeffson's fracture associated with Hangman fracture), 6 of C1 burst fractures and 5 of C2 vertebral body fractures. While only 38 cases (38/69) were correctly diagnosed according to roentgenographs, 23 missed diagnosis, 6 couldn't be diagnosed clearly and 2 misdiagnosis. The position of internal fixation could be seen clearly in CT imaging after surgery. There were two screws perforated the lateral wall of C1 and three perforated the superior wall.
CONCLUSIONThe multi-spiral CT thinner-scanning, three dimensional reconstruction (3D) and multi-planar reconstruction (MPR) provide clear imagings to diagnose the details of atlantoaxial fractures and dislocations, and to select the therapeutic regimen. It can also be used to check the position of the internal fixation after surgeries. So it can be the first eikonic choice for atlantoaxial injuries.
