We reported a clinical caseof gas gangrene in the lower back and buttocks due to local intramuscular injection. A 43-year-old male was treated by local private clinic for low back pain. He underwent local intramuscular injection in his lower back and buttocks. 5 or 6 hours after the treatment,he felt worsen of low back pain (VAS 5 points)with a fever. After one day of treatment, the lower back pain was even worse(VAS 8 points). And he had soy-sauce urine and a high fever. The results of laboratory examination and clinical manifestation suggested multiple organ failure within a short period of time. Imaging (CT) suggested large area of gas and muscle necrosis in the lower back and buttocks. Considering the progress of the disease, emergency surgery on lumbar back and right buttocks was performed after hospitalization. Rapid bacterial smear reported gram-positive coarse bacteria. Anaerobic culture suggested clostridium perfringens. Aerobic culture result did not show any bacterial growth. According to the clinical manifestation, imaging (CT), intraoperative judgment and postoperative anaerobic culture results, the clinical diagnosis was gas gangrene. Gas gangrene is a special infectious disease in clinic, which can be characterized by low morbidity, difficult early diagnosis,rapid disease progression and high mortality. Sinceintramuscular injection leaded to this disease in our case, the importance of standardized aseptic procedures should be emphasized.

BACKGROUND: Poor mental health status of nursing students can affect their learning and living. OBJECTIVE: To explore mental health status of nursing students at different studying stages.DESIGN: Grouping stratified sampling survey on the basis of nursing students studying in higherschool.SETTING: Nursing Department of the Fourth Military Medical University of Chinese PLA, Laboratory Center of Basic Faulty, and Department of Rehabilitative Physioltherapy of Xijing Hospital.PARTICIPANTS: Totally 515 nursing students at different studying stages of three educational levels (the technical secondary school level, junior college level and undergraduate level) were observed with grouping stratified sampling in December 2004.METHODS: Symptom checklist-90(SCL-90) was used for survey. SCL-90 contained 90 items, being interpreted in the context of nine symptom dimensions, including somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism. Each item was scored from grade Ⅰ to grade Ⅴ (symptomless, mild, moderate, little severe, and severe). Scores of total items and 9 symptoms were recorded. The more the scores of total items were, the lower the total level of mental health was; the more the scores of any symptom was, the severer the symptom of mental health was. Data were analyzed with t test. MAIN OUTCOME MEASURES: Scores of total items and 9 symptoms. RESULTS: Totally 515 nursing students were randomly selected in this survey except 5 students because of uncompleted survey, and the response rate was 99.0%. There were 501 qualified questionnaires, which were accounted for 98.2%. Mental health status of nursing students at various stages was different: the score of nursing students in grade 1 and 3 was higher than that in grade 2 in technical secondary school; the score of nursing students was the highest in grade 2 in junior college; and the score of nursing students was the highest in grade 3 at undergraduate level. The order of SCL-90 scores was obsessive-compulsive, interpersonal sensitivity and depression from high to low.CONCLUSION: SCL-90 scores of nursing students are high in grade 1and grade 3 at the technical secondary school level and also in middle grade at junior college level and undergraduate level. The main mental psychological symptoms are obsessive-compulsive, interpersonal sensitivity and depression. Psychological predisposition of nursing students should be cultured according to different psychological characteristics at various learning stages.

Objective To investigate the relationship between the genesis of hypertensive disorder complicating pregnancy and neurokinin B (NKB).Methods The serum NKB levels of 229 women including non-pregnant women (n = 62),normal pregnant women (n = 80) and pregnant women with preeclampsia (n=37) or gestational hypertension (n= 50) were examined by enzyme linked immunosorbent assay.The umbilical blood levels of NKB and the NKB mRNA expression in the pregnant women were also tested by fluorescent quantitative reverse transcription-polymerase chain reaction technique.ANOVA and paired t-test were applied.Results (1)The maternal plasma NKB levels of normal pregnant women,patients with gestational hypertension or preeclampsia were significantly higher than that of non-pregnant women,respectively [(28.2±6.6)μg/L,(31.5±5.2)μg/L,(70.5±8.9)μg/L vs(3.2±1.8)μg/L,P＜ 0.01].In preeclampsia,gestational hypertension and normal pregnancy group,the NKB level in umbilical blood [(121.4±9.3)μg/L,(60.5±7.2)μg/L,(40.8±6.3)μg/L] were significantly higher than that of maternal plasma(P＜0.01).(2) The maternal plasma NKB level in gestational hypertension group was higher than that in normal pregnancy group,while the difference had no statistical significance (P＞0.05).The maternal plasma NKB level in preeclampsia group was higher than that in gestational hypertension group and normal pregnancy group (P＜0.01).Forty-eight hours after delivery,the maternal plasma NKB levels significantly decreased in the normal pregnant,gestational hypertension and preeclampsia group [ (14.1±4.2) μg/L,(16.4±3.8) μg/L,(25.4±5.2) μg/L],compared to the values before delivery (P＜0.01).(3) The expression of NKB mRNA in placenta of preeclampsia group was significantly higher than that of gestational hypertension group and normal pregnancy group [(3.8±0.6) × 10-3 vs(1.7±0.4) × 10-3 and (1.6±0.3) × 10-3,P＜0.01].No statistical difference was found in the expression of NKB mRNA in placenta between gestational hypertension group and normal pregnancy group (P＞0.05).Conclusions Elevated NKB level in placenta and maternal or umbilical blood might play an important role in the development of hypertensive disorder complicating pregnancy.

Objective To use the enzyme linked immunosorbent (ELISA)to detect the hepatitis B virus (HBV)markers,and to perform the HBsAg quantitation and the HBV load detection for understanding the HBV carrying and viral replication situation when single HBcAb positive or both HBcAb and HBeAb positive.Methods The HBV markers HBsAg,HBsAb,HBeAg,HBeAb and HBcAb were detected with ELISA.1 098 cases of HBcAb positive,966 cases of both HBeAb and HBcAb positive and 832 cases of all HBV markers negative as control were selected and quantitatively re-detected HBsAg by using the chemiluminescence meth-od.The HBV load was detected by using the PCR method.Results Among 1 098 cases of single HBcAb positive,436 cases (39.7%)of HBsAg quantitation and 230 cases (20.9%)of PCR-DNA were detected out respectively;among 966 cases of both HBeAb and HBcAb positive,387 cases(40.1 %)of HBsAg quantitation and 212 cases(21.9%)of PCR-DNA were detected out re-spectively;among 832 cases of all HBV markers negative,6 case (0.7%)of HBsAg quantitation and 4 case (0.5%)of PCR-DNA were detected out respectively,there were statistically significantly differences among them (P < 0.05 ).Conclusion Adopting ELISA for detecting HBV markers,when single HBeAb positive or both HBcAb and HBeAb positive,HBsAg and the viral replica-tion are still be detected out,which needs to conduct further detection in order to avoid the medical risk due to the missed detection.
