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.

Objective To evaluate the association between the left carotid arterial stiffness and left ventricular diastolic function in patients with lower extremity atherosclerosis (AS).Methods ①A total of 32 patients with AS and 34 control objects were enrolled.The carotid arterial stiffness parameters:compliance coefficient (CC),distensibility coefficient (DC),stiffness parameter (α,β),pulse wave velocity β (PWVβ) were measured by using quality arterial stiffness(QAS) technology.And the values were compared between the two groups.②The parameters of left ventricular (LV) structure and function:LV end-diastolic interventricular septal thickness (IVSd),LV end-diastolic diameter (LVDd),LV end-diastolic wall thickness (PWd),LV ejection fraction (EF),systolic velocity (s'),early-diastolic velocity (e'),Tei index and E/e' ratio were measured by using two-dimensional echocardiography and tissue Doppler.These parameters were compared between the two groups.The association between the carotid arterial stiffness parameters and LV function parameters were analyzed by correlative analysis.Results ①Compared with the control group,the DC and CC were lower,and α,β,PWVβ,IMT were higer than the control group,with statistically significant differences(P ＜0.05).②The IVSd,Tei index and E/e'was significantly higher in the AS group than those in the control group.And the PWd,s',e' were lower than those in the control group (P ＜ 0.05).There was no significant difference in EF between the two groups (P ＞0.05).③The e' was correlated positively with DC and CC (r =0.39,0.36,P ＜0.01),and negatively with α,β,and PWVβ (r =-0.42,-0.42,-0.49,P ＜0.01).Tei index was correlated negatively with DC and CC (r =-0.50,-0.52,P ＜0.01),and positively with α,β,and PWVβ (r =0.58,0.58,0.62,P ＜0.01).The E/e' was correlated regatively with CC (r =-0.27,P ＜0.05),and positively with PWVβ (r =0.28,P ＜0.05).There were no significant correlation between s',EF and the stiffness parameters of carotid artery (P＞0.05).Conclusions In patients with AS,the left carotid artery stiffness increases and left ventricular systolic and diastolic function are impaired.The carotid artery stiffness and left ventricular diastolic function is correlated.Changes in carotid artery stiffness reflect the change in left ventricular diastolic function.

Objective To evaluate the correlation between left ventricular function and arterial stiffness of left femoral artery in patients with lower extremity atherosclerotic disease (LEAD).Methods Thirty-three patients with LEAD and 37 healthy subjects (control group) were enrolled in this study.The intima-media thickness (IMT),diameter and parameters of arterial stiffness [dispensability coefficient (DC),compliance coefficient (CC),stiffness α,stiffness β,pulse wave velocity (PWVβ) ]were measured by ultrasonography with the technology of QIMT and QAS.The thickness of the interventricular septum (IVSd),end-diastolic left ventricular diameter (LVDd) and left ventricular mass (LVM),and parameters of the left ventriculsr function (EF,E/A,E'/A',E/E' and Tei index) were measured by echocardiography.These parameters were compared between two groups.Correlations between the parameters of the arterial stiffness and those of the cardiac function were evaluated by Pearson correlative analysis.Results ①The IVSd,LVM and E/E' ratio were significantly higher in LEAD group than those in control group ( P ＜0.05).There were no significant differences in EF,E/A,E'/A',and Tei index between two groups ( P ＞0.05).②The IMT,α,β,PWVβ of left femoral artery were significantly higher in LEAD group than those in control group,while DC and CC were significantly lower in LEAD group than those in control group ( P ＜0.05).③The E/E' ratio,one of the parameters representing the left ventricular diastolic function,was correlated negatively with CC and positively with α,β,and PWVβ ( P ＜0.05 or P ＜0.01 ).The E'/A' ratio was correlated positively with DC and CC,and negatively with α,β,and PWVβ ( P ＜0.05 or P ＜0.01 ).Both EF and Tei index were not significantly correlated with the above parameters of arterial stiffness ( P ＞0.05).Conclusions Patients with LEAD have thickened femoral IMT,higher arterial stiffness of left femoral artery,as well as impaired left ventricular function.There is a close correlation between the atherosclerosis of the femoral artery and the early left vcntricular dysfunction.

Objective To find out the importance of human bocavirus (HBoV) as an infectious agent for population in Beijing, China. Seroprevalence study was conducted by using expressed recombinant major capsid VP2 protein as an antigen.Methods Serum specimens collected from infants and children who visited the Children's Hospital Affiliated to the Capital Institute of Pediatrics for health check-up and adults visiting the Xuanwu Hospital, Beijing for diseases other than respiratory infections from April 1996 to March 1997 were used for the investigation. The major capsid protein VP2 from HBoV was expressed in E. coli strain BL21 (DE3) with the transformed PET30b vector inserted with full-length VP2 gene of HBoV and the specific antigenicity of this expressed protein was validated by previous study. Western blotting was used to detect specific IgG antibody against HBoV in collected serum specimens diluted to 1:200. Mock expressed protein was E. coli cells strain BL21 (DE3) with the transformed PET30b vector without insert. Anti-His monoclonal antibody and rabbit anti-HBoV VP2 polypeptides hyper-immune serum were used as positive control for antibody detection.Results Out of 677 serum specimens tested, 400 (59.1% ) were positive for HBoV by Western blotting. About 45.3% (34/75) of the newborns under 1 month of age had anti-HBoV antibodies, and antibody positive rates were decreased in age groups of 1 and 2 months (41.4% and 31.3%, respectively) then increased in the following ages from 6 months to 7 years old ( from 45.6% to 69.7% ). The antibody positive rates were maintained at a relatively constant level ( about 70% ) in the age groups from 7 years to 40 years of age and became lower ( 61.8% - 62. 8% ) in those over 50 years.Conclusions The high seroprevalence of antibody against recombinant HBoV VP2 protein and early age antibody acquisition indicate that HBoV has been circulating in population of Beijing, China as early as in 1996 and most of children had been exposed to HBoV by the age of 7 years. Infants under the age of 6 months were susceptible to this virus.

The cry gene family, produced during the late exponential phase of growth in Bacillus thuringiensis, is a large, still-growing family of homologous genes, in which each gene encodes a protein with strong specific activity against only one or a few insect species. Extensive studies are mostly focusing on the structural and functional relationships of Cry proteins, and have revealed several residues or domains that are important for the target recognition and receptor attachment. In this study,we have employed a maximum likelihood method to detect evidence of adaptive evolution in Cry proteins, and have identified 24 positively selected residues, which are all located in Domain Ⅱ or Ⅲ. Combined with known data from mutagenesis studies, the majority of these residues, at the molecular level, contribute much to the insect specificity determination. We postulate that the potential pressures driving the diversification of Cry proteins may be in an attempt to adapt for the "arm race" between δ-endotoxins and the targeted insects, or to enlarge their target spectra, hence result in the functional divergence. The sites identified to be under positive selection would provide targets for further structural and functional analyses on Cry proteins.

The aim of this study was to obtain the capsid protein VP2 of human bocavirus (HBoV) identified in Beijing recently and construct virus-like particles (VLPs) in insect cells for further study of this virus. The full-length VP2 gene of HBoV from BJ3722 was inserted into the baculovirus expression transfer vector (pFastBac 1) to obtain the recombinant Bacmid, and generation of recombinant baculoviruses was followed by transfection of the recombinant Bacmid into insect cells. Then the recombinant VP2 protein was recognized by SDS-PAGE using Coomassie-blue staining and Western blot using hyper-immune serum against VP2 of HBoV from rabbit. The recombinant baculoviruses were harvested and amplified to gain large amounts of viruses with high titers to infect insect cells at a multiplicity of infection (MOI) of 0. 5. After 7-10 days or 4-5 days of the infection, the supernatants of culture or the cell lysates treated with lysing solution were harvested, and ultracentrifuged twice through 40% sucrose cushion to obtain purified VLPs, which were followed by Western blot and IFA for VLPs' composition and specificity analysis, by electron microscopy for VLPs' morphologic structure. The recombinant VP2 protein with molecular weight of approximately 61 kD expressed in recombinant baculoviruses was recognized by SDS-PAGE using Coomassie-blue staining and Western blot. The presence of VP2 on VLPs was demonstrated by Western blot and IFA from samples collected during the purification of VLPs from the supernatants of culture or the cell lysates, and the expression of VP2 in insect cells led to the formation of VLPs which formed the typical icosahedral appearance of parvoviruses with a diameter of approximately 20 nm. In conclusion, the recombinant baculoviruses were constructed, the HBoV VP2 protein was expressed in insect cells with high specific antigenicity and VLPs was formed successfully.

OBJECTIVEAn outbreak of acute respiratory infections in children occurred in Beijing from November to December, 2002. To investigate the etiological agents of affected children who were in day care centers and primary schools.

METHODSThroat swab specimens were collected from one primary school children with acute respiratory infections visiting one outpatient department. After centrifuging, supernatant from the specimens were inoculated into MDCK and Hep-2 cells for virus isolation and pallets for viral antigen detection and using indirect immunofluorescent assay on common respiratory viruses. Nested polymerase chain reaction was used at the same time for detection of respiratory viruses and Mycoplasma pneumoniae (Mp).

RESULTSA total number of 80 specimens were collected during the outbreak. Among them influenza B virus were detected from 18 specimens, with a positive rate of 22.5% (18/80) while Mp were detected from 13 specimens, with a positive rate of 16.3% (13/80). Influenza A3 were also detected from 2 patients (2.5%, 2/80). However, influenza A1, RSV, adenovirus and parainfluenza viruses were not found from these specimens. Influenza B virus and Mp were detected simultaneity in two specimens and influenza A3 virus and Mp were detected in one specimen.

CONCLUSIONThe outbreak of acute respiratory infection in children during the period of investigation was caused by both influenza B virus and Mp.

OBJECTIVETo develop a rapid, sensitive and specific method in identifying and typing on adenovirus from clinical specimens.

METHODSPrimers were designed using hexon gene of adenovirus as target. One primer pair was designed as universal primers for amplifying a 1278 bp gene fragment located at the hexon gene of adenovirus from all types. Four primer pairs located within the region of this 1278 bp were specifically designed for amplifying types 3, 7, 11 and 21 of adenoviruses, which were used for multiplex nest-PCR in a single tube. The products from this multiplex nest-PCR were 502 bp (for type 3), 311 bp (for type 7), 880 bp (for type 11) and 237 bp (for type 21), respectively. Type of the adenovirus tested could then be determined after agarose electrophoresis analysis of the PCR products.

RESULTSPCR products with predicted sizes were visualized in the agarose gel for prototype strains of adenovirus types 3, 7, 11 and 21, but not for other respiratory viruses, indicating that the technique was specific without cross reaction with other viruses. Out of the 118 clinical specimens which had been proved to be adenovirus positive by tissue culture and/or immunofluerescence assay, 76 belonged to adenovirus type 3 (76/118, 64.4%), 37 to adenovirus type 7 (37/118, 31.4%), 3 to adenovirus type 11 (3/118, 2.5%) but no adenovirus type 21 was detected. Two of the 118 positive specimens which were positive by both tissue culture and immunofluerescence could not be identified, suggesting that these 2 strains (1.7%) were with the types other than types 3, 7, 11 and 21. Out of the 33 specimens which were negative by both tissue culture and immunofluerescence, 3 showed positive by this multiplex PCR (2 of type 3 and 1 of type 7), suggesting this method was more sensitive than tissue culture and immunofluerescence.

CONCLUSIONThis multiplex nest-PCR method had the benefit of rapid,sensitive and specific nature so could be used for identifying types of adenoviruses in the clinical specimens.
