Objective To study the influence of exposure factors on posttraumatic stress disorder( PTSD) and Posttraumatic Growth( PTG) in middle school students in disaster area four years after the Wenchuan earth?quake . Methods 1 526 students from four schools in Worst?Hit Areas were investigated with Self?compiled Earth?quake Exposure Factors Questionnaire,Posttraumatic Growth Inventory( C?PTGI) and Impact of Event Scale( IES?R). Data were analyzed by ANOVA and multiple linear regression analysis.Results The score of IES?R had sig?nificant difference between different levels of all exposure factors(F=5.75~89.10, P<0.05) ,and students with high exposure level((26.68±14.66),(26.80±15.56),(27.83±14.62),(29.02±15.36),(27.77±15.74),(26.74± 15.63),(25.43±14.32),(29.51±14.36)) had heavier symptoms of PTSD than those with low exposure level ((22.84±13.96),(23.98±13.99),(23.63±14.21),(23.53±13.96),(23.64±13.83),(24.24±14.15),(21.27± 14.35),(17.54±13.34)). Only exposure factors of having witnessed someone injured and having close friends se?riously injured or being killed could significantly influence the score of PTGI(F=11.82, P=0.001;F=6.23, P=0.013). Regression analysis showed that five exposure factors (grade,having felt scared,having family members being killed,having close friends seriously injured or being killed,having witnessed someone injured) had signifi?cant effect on IES(ΔR 2=0.141) ,but only one factor( having witnessed someone injured) had weak effect on PTG (ΔR 2=0.007).Conclusion Exposure factors can predict posttraumatic stress symptoms in middle school students in Wenchuan four years after the earthquake,and the emotion of fear is a strongest predictor,but they can not pre?dict posttraumatic growth.

Objective: To observe the clinical efficacy of warm needling moxibustion plus spine subtle adjusting manipulation for cervical radiculopathy. Methods: A total of 70 patients with cervical radiculopathy were randomized into an observation group and a control group, with 35 cases in each group. The observation group was treated with warm needling moxibustion plus spine subtle adjusting manipulation, while the control group was treated with warm needling moxibustion alone. The treatments were performed three times a week, and for four weeks in total. The visual analog scale (VAS) was scored before and after treatment. And the clinical efficacy of the two groups was compared after treatment. Results: The total effective rate was 97.1% in the observation group, versus 88.6% in the control group. The difference between the two groups was statistically significant (P<0.05). After treatment, the VAS scores in both groups significantly decreased (P<0.01), and the score in the observation group was significantly lower than that in the control group (P<0.05). Conclusion: Warm needling moxibustion plus spine subtle adjusting manipulation has a better effect in the treatment of cervical radiculopathy than warm needling moxibustion alone.

A multiplex real-time PCR was developed to detect ctxA of Vibrio cholerae, gyrB and tdh of Vibrio parahaemolyticus simultaneously. The multiplex real-time PCR were evalidated by detection for the three genes in 47 toxigenic V. cholerae O1 and O139 strains (ctxA+; O1=3, O139=44), 25 non-toxigenic V. cholerae strains (ctxA-; O1=12, O139=6, non-O1 and non-O139=7), 116 V. parahaemolyticus strains with or without tdh (73 or 43) and 9 other bacteria strains. The specificity and sensitivity of the multiplex real-time PCR in detection for the ctxA and the tdh genes in the strains tested were both 100.0%, compared to the results by routine PCRs. In the detection for V. parahaemolyticus specific gyrB using the multiplex real-time PCR, all of 116 V. parahaemolyticus strains were positive, and 9 other strains and 72 V. cholerae strains were all negative. The multiplex real-time PCR is a sensitive, specific and quick assay not only for detecting virulence genes of V. cholerae and V. parahaemolyticus but also for identifying V. parahaemolyticus at species level. In addition, two real-time PCRs for detection of V. parahaemolyticus virulence genes trh1 and trh2 were also developed.
