Objective To explore the effect of double cypress powder (DCP) combined with TDP irradiation on lumbar intervertebral disc protrusion and summarize nursing experience.Methods One hundred and twenty-five patients with lumbar intervertebral disc protrusion were randomized into the observation group and control group.The control group was treated with massage and electro-acupuncture and the observation group received DCP fumigation combined with TDP irradiation besides treatments the controls received.The two groups were compared in terms of pain level and curative effect after two courses of treatment.Result The score on pains by VAS in the treatment group was significantly lower than that in the control group and the curative effect was better than that in the control group (P<0.05).Conclusion On the basis of the massage,electro-acupuncture and moxibustion therapy,DCP combined with TDP irradiation is therapeutically effective in the reduction of the pains from lumbar disc protrusion.

To study the effect of vascular proliferation and reconstruction in chronic hepatitis B (CHB), immunohistochemical staining and in situ hybridization were used. The expression of transforming growth factor (TGF-?1) and smooth muscle actin (?-SMA) in livers of CHB were observed. The results showed that TGF-?1 and ?-SMA were related with degeneration of hepatocytes, intrahepatic vascular fibrosis and hepatic sinusoidal capillarization. The expression degree and range of TGF-?1 and ?-SMA increased with the exacerbation of liver lesion. These results suggest that vascular proliferation and reconstruction may play important roles during the process of CHB.

Conclusion The new modality of nursing care and convalescence guide is effective on RF for cervical disc herniation.

Objective To explore the perioperative nursing care of cooled radiofrequency for refractory craniofacial postherpetic neuralgia.Methods 13 refractory craniofacial postherpetic neuralgia patients were reviewed. Results Visual analogue score significantly decreasedafter the treatment (P<0.01), and severe dropsy after treatment was relieved in 2~3 weeks. Conclusion The cooled radiofrequency iseffective on refractory craniofacial postherpetic neuralgia, while the perioperative nursing care was safe, feasible, and worthy for more application.

Objective To explore a modality of ambulatory nursing care applied to the elderly patients with severe trigeminal neuralgia treated by radiofrequency thermocoagulation.Methods42 patients were equally assigned into 2 groups: group A(n=21) aged from 40～60, and group B(n=21) aged from 80～92. Pertinent nursing measures were assessed for risks of ambulatory surgery, including psychological care before surgery and intensive observation during surgery. The pain was assessed with Visual Analogue Scale (VAS) between the groups and before and after surgery, as well as complications.ResultsNo significant difference of the VAS scores was found between the groups before and 2 weeks after surgery (P>0.05), while the score of VAS decreased in two groups 2 weeks after surgery(P<0.01). No severe complication occured in the groups after surgery.ConclusionIt is safe and effective to apply the modality of ambulatory nursing care for the elderly patients with severe trigeminal neuralgia treated by radiofrequency thermocoagulation.

Objective To evaluate the clinical value of epicardial echocardiographic examination in cardiac valve surgery.Methods Epicardial echocardiography were performed in 46 patients undergoing valvular plasty or valvular replacement surgery to estimate the function of valve and left ventricle and residual shunt during cardiac surgery.Results Twelve cases of 46(26.1％)showed abnormality during cardiac surgery.Two cases of 15 patients performed valvuloplasty were changed to valvular replacement because of remarkable regurgitation of native valves.There was 1 case of periprosthetic leakage,3 cases of left atrial appendage thrombus,1 case of patent foramen ovale and 5 cases of low ejection of left ventricle in all 31 cases of valvular replacement.Conclusions Epicardial echocardiograpyc examination is an effective examination in cardiac valve surgery with clearly image,simplicity operation and promptness.

ObjectiveTo investigate the effect of SalB on bone marrow-derived mesenchymal stem cells (BMSCs) apoptosis induced by hypoxia and serum deprivation (hypoxia/SD) in the vitro. Methods BMSCs were cultured in the vitro and randomly divided into control group, hypoxia/SD group and SalB group.SalB group was composed by four groups and were pretreated by complete medium with 0.1、 1、 10、 100 mg/L SalB for 1 hour. And after that they were washed with phosphate buffer for 2 times, added by IMDM with 0.1、1、 10、 100 mg/L SalB and cultured with hypoxia/SD group together in the same condition of hypoxia/SD for 6hours. The control group was cultured for 6 hours in the condition of aerobic and enough serum. Apoptosis was detected by Hoechst33342 staining with inverted phase contrast, fluorescence microscope and Annexin V/PI dual-color flow cytometry. Results Significant apoptosis of BMSCs was induced by hypoxia/SD in the vitro.The early apoptosis of BMSCs induced by hypoxia/SD was significantly decreased by SalB of 0.1、 1、 10 mg/L(P＜0.05) . Conclusion0.1、 1、 10 mg/L SalB can decrease the early apoptosis of BMSCs induced by hypoxia/SD.

ObjectiveTo study the expression of telomerase of fibroblasts in the formation and development of scar,and to investgate the relationship between the telomerase activity and the formation and development of scar.MethodsExpression of telomerase was detected by immunohistochemical techniques in 18 specimens from granulation tissue,17 keloid,16 specimens from hypertrophic scar,28 specimens from mature scar,32 specimens from normal skin,and SPSS16.0 statistics software was used to analyze the relationship between telomerase and scar.Results It was shown that the positive expression rate of telomerase in the granulation tissue group was 94.4 ％,that in the keloid group was 58.8 ％,that in the hypertrophic scar group was 18.8 ％, and that in the mature scar and in the normal skin was zero. comparisons between groups,in addition to the normal scar group and normal skin group,other groups were statistically significant differences.ConclnsionsScar formation is a process with multi-factor participation,while telomerase activation is an important factor. Detecting telomerase activity in the development process of scar formation may determine the prognosis.Through the control of telomerase activity in the pathogenesis of scar may become a new approach of scar treatment.
