Objective The aim of this study was to explore the effects of volume controlled ventilation (VCV),pressure controlled ventilation(PCV)and pressure controlled ventilation-volume guaranteed (PCV-VG)on respiration and circulation in elderly patients undergoing thoracic surgery. Methods Thirty-six elderly patients who underwent thoracic surgery were enrolled in our study. Patients were divided into VCV,PCV and PCV-VG groups according to randomized design. The hemodynamic and respiratory data and the arterial blood gases had been recorded in the pre-operation,20 min,40 min,60 min after OLV and 20 min after the resumption of two lung ventilation. Results Compared with VCV group,Ppeak value was significantly lower in PCV and PCV-VG groups(P < 0.05),and the difference was not found between the PCV and PCV-VG groups. PaO2 levels in PCV and PCV-VG groups were higher than that in VCV group after the point of OLV+40(P < 0.05). Comparison of PCV group,PaO2 in PCV-VG group was higher,but did not show a significantly improved during OLV(P > 0.05). Conclusion Compared with VCV,the use of PCV and PCV-VG have significant advantages in the operative oxygenation and airway pressure for elderly patients undergoing OLV.

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.

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

Integrative medicine is the effective combination of dual diagnosis of Chinese medicine and western medicine.The combination can broaden the scope of clinical diagnosis and combine the local pathological changes with the overall response of the human disease.It can add a more comprehensive understanding of diseases for people.Clinically treated with combination of Chinese medicine and western medicine can achieve the complement of advantages.It is significant.Because the theory system of Chinese medicine compared with western medicine is different and the theory system of combination is not practical and standardized.The methods of clinical diagnosis and treatment are also different.So there are still some problems and deficiencies in the integrative medicine.In this study,through extensive literature research,as well as the clinical investigation in some integrative medicine hospitals and the collection of related clinical data,we compared and analyzed the academic ideas and different features of Chinese medicine and western medicine,analysed the status and the insufficience of current clinical integrative medicine.Finally,we put forward a series of effective strategies and methods for how to combine with integrative medicine in a specific,reasonable and effective way.

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.

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.
