Objective To evaluate the therapeutic effects of EN,PN support on postoperative recovery of (patients) with portal hypertension. Methods 135 patients with portal hypertension who underwent (esophagogastric) devasularization were randomly divided into three groups:EN,PN and control group. (Postoperatively), EN and PN nutritional support and routine fluid replacement therapy was respectively given to the 3 groups. Several clinical and laboratory parameters were studied in order to determine the therapeutic effect of the two different forms of nutrition.Results Nutritional status and immunological function of patients were improved in both EN and PN study groups but with no significant difference, while alterations in liver function and incidence of abdominal infection were higher in PN group. Conclusions EN is an optimal form of nutritional support for patients with portal hypertension after operation.

Objective:To investigate the analysis of features and differential diagnosis of ultrasonic image for patient with endometrial lesions.Methods: The imaging data of 80 patients with endometrial lesions were selected as random number table. The relevant ultrasound manifestations and sonographic features of patients were further analyzed, and then these data were compared with the pathological diagnosis by using operation.Results: In the 80 patients with endometrial lesions, 43 cases were endometrial polyps, and in the 43 cases, there were 41 cases were consistent with the pathological diagnosis and the diagnostic accordance rate was 95.35%, while there were 2 cases were not consistent between the two methods. 33 cases of the 80 patients were submucous myoma of uterus, and there were 29 cases of them were consistent with the pathological diagnosis and the diagnostic accordance rate was 87.88%, while there were 4 cases were not inconformity. And 4 cases of the 80 patients were endometrial carcinoma, the result was completely consistent with the pathological diagnosis and the diagnostic accordance rate was 100%. In the 6 misdiagnose cases, the ratios of atypical cases and (or) typical cases were 1:16, 5:36 and 1:8, respectively. All of these endometrial lesions has the distinctive manifestations on the ultrasonoscopy of color Doppler.Conclusion: For the detection of endometrial lesions, transvaginal colar Doppler ultrasonic detection has unique feature of ultrasonogram compared with other detection methods. In the contrast, there is a regular congruent relationship between the ultrasonogram of typical disease and section of pathological specimen by using operation in a certain degree, and the ultrasonogram of typical disease has definite diagnosis value.

Rabbits were intoxicated with hypodermic injection of 0.8% CdCl2 in normal saline every other day for 3 months,and the blood level of urea nitrogen (BUN) and creatinine (Cr) and the activities of Na/K-ATpase,Ca-ATPase,and ?-GT in the renal cortex were determined.It was found that there were no remarkable changes of BUN and Cr level but significant reduction of the activities of the 3 enzymes.It is believed that the reduction of the enzyme activities is one of the factors to initiate the functional disturbances and morphological damages of the kidneys and plays an important role in the mechanism of renal failure if it is not promptly corrected.

BACKGROUND:Regulation of neural stem cells differentiation hampers its application,and the regulation mechanism remains poorly understood.Anterior subventricular zone(SVZa)is one of the rich zones of neural stem cells.The neural stem cells at SVZa can immigrate for a long distance with undifferentiated states and finally differentiate into intemeurons at the olfactory bulbs.Bone morphogenetic protein-2(BMP2)and DLX5 play a significant role in immigration and differentiation of neural stem cells at SVZa towards olfactory bulb.OBJECTIVE:To study the feature of construction and immigration of neural stem cells at SVZa,and to review the role of BMP2 and DLX5 in neural stem cells differentiation,in addition,to explore the regulation mechanisms of neural stern cells differentiation.METHODS:Literatures from PubMed database(http://www.ncbi.nlm.nih.gov/PubMed),CNKI database(www.cnki.net/index.htm)and WANFANG database(http://www.wanfangdata.com.cn)published between January 1997 and January 2009 were searched with the key words of"neural stem cells,SVZa,BMP2,and DLX5".The repetitive and obsolete studies were excluded.RESULTS AND CONCLUSION:A total of 121 literatures were selected and primarily collected,including 86 Chinese literatures and 35 English literatures.Finally,according to standardization,28 literatures were further analyzed.Neural stem cells of SVZa have unique construction and can immigrate for a long distance.BMP2 and DLX5 play a significant role in neuronal immigration and differentiation of the NSCs of SVZa,but the detailed mechanism of BMP2 and DLX5 in SVZa is not clear.

BACKGROUND: Traditional treatment includes conservative therapy and surgical treatment on bronchial pleural fistula. With the development of endoscopic therapy, a new safe and effective method is concerned. OBJECTIVE: To summarize the therapeutic effect of treating bronchopleural fistula using bronchoscopy-guided injection of fibrin sealant combined with gelatin sponge filled and microwave following after lung resection. METHODS: Totally 8 cases of bronchial fistula patients were received injection of fibrin sealant after microwave and gelatin sponge filled by bronchoscopy, including 6 males and 2 females, mean aged 53.8 years (39-73 year-old). Cases 1 and 2 received left upper pulmonary Iobectomy, cases 3 received left lower pulmonary Iobectorny, case 4 received right lower pulmonary Iobectomy, cases 5 and 6 received right upper pulmonary Iobectomy, and the cases 7 and 8 received pneumonectomy. bronchopleuralfistula occurred after postoperative Chemotherapy in cases 4 and 8. RESULTS AND CONCLUSION: The case 8 was failed to treatment due to the large orificium fistulae (> 5 mm) and disappointed results after 6 times plugging. The other 7 patients were cured successfully. The injection time was correlated to the size of orificium fistulae, and the plugging was successful for 4 patients with less than 3 mm orificium fistulae. However, a third or fifth plugging was performed for 3 cases with 3-5 rnm orificium fistulae. No surgery-related complications occurred in all patients. Bronchoscopy guided injection of fibrin sealant combined with gelatin sponge and microwave is a safe and effective method for bronchial fistula.

Objective To investigate the influence and the clinical significance of interleukin-2 (IL-2) on T lymphocyte subgroup after chemotherapy in acute myeloid leukemia patients. Methods Fiftyfour acute myeloid leukemia patients were divided into treatment group (chemotherapy combined with IL-2,28 cases) and control group (pure chemotherapy,26 cases) by radom digits table. In treatment group, IL-2400 000 U was dripped after chemotherapy for 14 days. Then the T lymphocyte subgroup change before and after treatment was examined. Results After 14 days' treatment, the levels of CD3 (0.6026±0.2275 ),CD4(0.4972±0.1224),CD56(0.3016±0.1053 ) in treatment group were significantly higher than those before treatment(0.3926±0.2010,0.2264±0.1190,0.1729±0.1226) and in control group (0.4352±0.1930,0.2738±0.1362,0.1937±0.1268)(P< 0.05). Conclusion IL-2 treatment can obviously raise the levels of T lymphocyte subgroup and can raise the immunologic function.
