BACKGROUND:Studies have shown that genetical y modified Schwann cel s can survive for a longer time in vivo, and promote nerve regeneration and functional recovery. OBJECTIVE:To transfect human telomerase reverse transcriptase (hTERT) gene into rat Schwann cel s cultured in vitro via PLXSN vector, and to detect the telomerase activity and biological characteristics of Schwann cel s. METHODS:Schwann cel s from Wistar rats were cultured in vitro and transfected by PLXSN vector with (hTERT group) or without hTERT (empty vector group). Normal Schwann cel s were selected as control group. RT-PCR and western blot methods were used to detect the hTERT protein and mRNA levels in Schwann cel s, and flow cytometry was used to measure the cel cycle distribution. Cel growth was observed by cel growth curve and MTT colorimetric method. RESULTS AND CONCLUSION:At 48 hours after transfection, the mRNA and protein expressions of hTERT were remarkably seen in Schwann cel s. Compared with the control and empty vector groups, the cel s grew faster, the number of cel s at G 0/G 1 Schwann cel s cultured in vitro. phase was reduced, but the number of S phase cel s was increased in the hTERT group (P<0.05). These findings indicate that PLXSN vector-mediated hTERT transfection of Schwann cel s can significantly improve the activity of telomerase in Schwann cel s as wel as promote the proliferation of Schwann cells cultured in vitro.

Objective To investigate the correlation between anatomical structure and recurrence of common bile duct stones.Methods The clinical data of 195 patients with common bile duct stones were studied,including 37 patients with recurrent bile duct stones.The correlation between anatomical structure and the recurrence of common bile duct stones were analyzed by univariate and multivariate analysis.Results Univariate analysis revealed that history of cholecystectomy,choledocholithotomy,periampullar diverticu-lum,papilla hypertrophy or stenosis,intramural duodenal bile duct abnormalities,common bile duct stric-ture,choledochectasia and angulated common bile dust were risk factors of recurrence.Multivariate logistic regression analysis showed that past history of cholecystectomy,periampullary diverticulum,angulated com-mon bile dust,choledochectasia were independent risk factors for the recurrence of common bile duct stones. Conclusion Patients with anatomical structure of past cholecystectom,periampullary diverticulum,choledo-chectasia,angulated common bile dust are prone to recurrence of common bile duct stones.

ObjectiveTo observe the clinical efficacy of acupuncture plus TDP (specific electromagnetic treatment apparatus) and auricular point sticking in treating chronic pelvic infection.MethodSixty patients diagnosed with chronic pelvic infection were randomized into two groups. Thirty cases in the treatment group were intervened by acupuncture plus TDP and auricular point sticking, while the other 30 in the control group were by acupuncture plus TDP, 10 d as a treatment course in both groups, and the therapeutic efficacies were compared after 3 courses.ResultThe total effective rate was 96.7% in the treatment group versus 83.3% in the control group, and the difference was statistically significant (P<0.05).ConclusionAcupuncture plus TDP and auricular point sticking can produce a marked therapeutic efficacy in treating chronic pelvic infection, and its total effective rate is higher than that of acupuncture plus TDP.

Objective: To investigate the efficacy of the green tortoise exploring point technique for treating piriformis syndrome. Methods: Ninety patients were randomly allocated to a green tortoise exploring point treatment group of 30 cases, an acupuncture control group of 30 cases and a hydro-acupuncture control group of 30 cases for clinical observation. Results: The symptoms improved after treatment in all the three groups. The total efficacy rate was 100.0% in the treatment group, 76.7% in the acupuncture group and 83.3% in the hydro-acupuncture group. There were statistically significant differences between the three groups (P<0.01, P<0.05). Conclusion: The technique of green tortoise exploring point is better than conventional acupuncture and hydro-acupuncture in treating piriformis injury syndrome

Objective To argue whether the Chinese version of Emotional Intelligence Scale (EIS) can be used to evaluate emotional intelligence of nursing students through studying its reliability and validity,and provide basis for the study of emotional intelligence of nursing students.Methods Using stratified random sampling method,Chinese version of EIS compiled by Wang Caikang was used to carry out the questionnaire survey among university and college students of different nursing specialty,using Cronbach coefficient alpha and factor analysis method to study the reliability and validity.Results Each dimension and total reliability of the Chinese version of EIS were 0.735,0.815,0.801,0.790,0.821.Through the principal component analysis,four common factors were extracted,the cumulated variance contribution of the four factors was 55.468％.Conclusions Chinese version of EIS has good reliability and validity,which is fully applicable to nursing students' emotional intelligence research.

AIM: To extract Zanthoxylum oil from the seeds of Zanthoxylum bungeanum Maxin, and find out a better extraction method and its optimized operating conditions. METHODS: Zanthoxylum oil was extracted by distillation method, solvent extraction and supercritical fluid extraction, respectively. The products gained in each experiment was analyzed by GC after it had been methyl esterified. RESULTS: The yield of Zanthoxylum oil extracted by distillation, solvent extraction and supercritical fluid extraction was 0.88 %, 13.73 % and 13.52 %, respectively, and its content of unsaturated fatty acid 4.50 %, 65.97 %, 74.97 %, respectively. CONCLUSION: Supercritical fluid extraction was the better of the three mehtods, whose optimized operating conditions consisted of 30 MPa pressure, 50 ?C operating temperature and 5 h extraction time.

The irregular anatomic morphology of proximal femoral medullary cavity does not match the current regular prosthetic stem,which is a primary cause of prosthesis loosening post-surgery. The newly designed artificial furcal interior locking joint features irregular prosthetic stem, which adapts to the irregular medullary cavity in the proximal femur. The artificial furcal interior locking joint is anchored in a multi-plane and multi-point manner. Together it can prevent prothetic early peristalsis and late loosening in the medullary cavity post-surgery. Therefore, artificial furcal interior locking joint is promising for prosthetic replacement.
