Objective To investigate the status and influential factors of mental health of Pakistani and Bangladeshi peacekeeping forces in Liberia.Methods By random sampling,300peacekeeping officers and soldiers dispatched from Pakistan and Bangladesh(150 each)in Liberia were investigated with Chinese Military Mental Health Scale(CMMHS),Military Mental Maladjustment Scale(MMMS) and Social Support Rating Scale(SSRS),and they were carried out for two times on the 7th day and the 120th day after arrival in peacekeeping mission area.Results The total score and each factor score of CMMHS(except for obsessive-compulsive,anxiety and interpersonal sensitivity)and the total score of MMMS of the peacekeepers at the 7th day after their arrival in mission area were significantly higher than those at the 120th day(P

Objective To develop a Chinese military psychosomatic health scale(CMPHS) and examine its reliability and validity. Methods Based upon the previous researches, the Scale was compiled according to open-ended inventory survey. The data was collected from 1050 subjects chosen by random cluster sampling. 60 of them were tested with the CPSHS at the same time, while 61 of them were retested with the CMPHS after two weeks. The reliability and validity were examined by exploratory factor analysis ( EFA) and correlation analysis. Results According to the factor analysis results, 11 factors were extracted, namely espiratory apparatus, alimentary system,skeletal and musculature,integument,regeneration and endocrine,nervous system, anxiety, depression, psy-choticism and family history. There were 91 items in the formal scale when one lie subscale was added. The correlation between subscales were 0. 103 ～ 0. 778 (P < 0. 01) , the correlation between subscales and total scale were 0.600 ～0.859(P<0.01). The test-retest correlation coefficients of total scale and subscales were 0.427 ～0.901 (P < 0.01); the Cronbach (α) coefficients were 0. 643 ～ 0. 935 (P < 0. 01) ; and the split-half correlation coefficients were 0. 349 ～ 0. 855 (P < 0. 01 ). The correlation coefficients were 0. 425 ～ 0. 979 (P < 0. 05 or 0. 01 ). Conclusion The Chinese military psychosomatic health scale has acceptable psychometrics properties on reliability and validity.

Objective To evaluate the test-retest and inter-rater reliability of the hand-held pressure algometer as a measuring instrument of pressure pain threshold(PPT).Method A total of 37 healthy subjects were recruited for reliability test.Three raters measured the PPT at 12 body sites of the subjects.Each rater conducted three trials on each site.In the validity test,10 patients with active trigger points in the upper trapezius were recruited and measured by one rater using the pressure algometer for PPT,the visual analogue scale(VAS)was also used to evaluate the pain intensity induced by the trigger point.The intraclass correlation coefficient and Spearman correlation coefficient were calculated to reflect the reliability and validity.Results The test-retest and inter-rater reliabilities were both high(ICC＞0.95),with the measurements by one rater were more reliable than measurements by multiple raters.The inter-rater reliability of PPT measurement obtained by using the mean value of 3 trials was higher than any of the 3 trials alone.The PPT values of the trigger points were higher than those of the normal points,and there was a significantly negative correlation between the PPT values of the trigger points and the VAS scores.Conclusion The intra-and inter-rater PPT measurements in healthy subjects obtained with the hand-held pressure algometer were highly reliable.The algometer was valid for quantifying myofascial trigger point sensitivity.

Objective This study aimed to study the effect of intra-brachial nitroglycerin administration via the angiography catheter on radial artery spasm in transradial percutaneous coronary intervention. Methods From patients undergoing transradial percutaneous coronary intervention (TRI) and succeeding in coronary angiography (CAG), 810 patients who needed percutaneous coronary intervention (PCI) (including Percutaneous Transluminal Coronary Angioplasty and/or stent implantation) were erolled, including 413 patients in the study group and 397 patients in the control group. When coronary angiography completed, positioned the angiography catheter over brachial artery and patients in the group received an administration of 400μg nitroglycerin via the angiography catheter. The control group received an administration of 400μg nitroglycerin via the sheath. The incidence of RAS were recored and compared. Resultes Baseline characteristics were similar between two groups. In the study group, the incidence of RAS was signiifcatively lower (18 vs. 33, P=0.021). Conclusions Intra-brachial nitroglycerin administration via the angiography catheter can prevent RAS during the insertion of guiding catheter in TRI.

A mouse model for acute hepatitis B virus (HBV) infection was established by using the hydrodynamical injection of mouse tail vein, in which the immunocompetent BALB/c mice were hydrodynamically injected with a competent replication plasmid pAAV-HBV1.2 having 1.2 fold over-length of HBV DNA. On day 1, 2, 4, 6 and 8 after injection, the levels of HBsAg, HBeAg and HBV DNA in blood serum were detected by using ELISA and fluorogenic quantitative PCR assay (FQ-PCR). And on day 8. HBsAg and HBeAg in liver tissue were assayed by immunohistochemical staining. It was found that HBsAg in blood serum could be detected on day 1 after infection in 14 of 16 mice (85.7%) injected with pAVV-HBV1.2 by using ELISA assay and the peak levels of HBsAg and HBeAg were attained during the first day after injection and then it dropped down gradually up to day 8 following injection. The titer of HBV DNA in blood serum attained its peak on day 2 and maintained a high level later on. On day 8 after injection, its titer was 1.9×10~4 copies/mL. The percentage of HBcAg-positive hepatocytes and HBsAg-positive hepatocytes in liver tissues were 5% and 2% respectively. Thus, by using the hydrodynamic injection with the competent replication plasmid, a mouse model for acute HBV infection is successively developed.

Methods All hospitals that have large medical equipment in Xuzhou were investigated and the cost, payment and benefit of 42 CT are analyzed. Results The median of cost is 142.6 yuan per person. The median of payment is 277.0 yuan per person. The median of annual net profit is 652 thousand yuan per CT. Conclusion The payment is higher than the cost of CT in Xuzhou. The ratio of profit is 120.8%, but half of CT can't take back of the investment in regular time.
