Objective To evaluate the perfectibility of colposcopy directed biopsy for the diagnosis of cervical intraepithelial(CIN)through cervial conization by loop electrosurgical excision procedure(LEEP).Methods Biopsy by colposcopy and biopsy after LEEP were analyzed retrospectively in 108 cases of cervical intraepithelial neoplasia to study the related factors of affecting the coincidence rate.Results Comparison of pathological hanges following both LEEP and colposcopy showed that 69 cases were the same,24 upgrade,and 15 downgrade.Conclusion LEEP is a kind of effective and perfect method for the specific diagnosis and treatment of CIN.Colposcopically directed biopsy has its limitations.

BACKGROUND: Scholars disagree with each other about the small saphenous vein effects on skin flap and how to dispose vascular proximal pedicles.OBJECTIVE: To analyze effects of different methods of the small saphenous vein disposal on flap survival using sural neurocutaneous island flap retrograde metastasis for repairing defects of soft tissue of instep, heelstick and ankle.DESIGN, TIME AND SETTING: The case control observation experiment was performed at the General Hospital of Guangzhou Military Area Command of Chinese PLA from March 1998 to April 2007.PARTICIPANTS: A total of 56 patients with defects of soft tissue of instep, heelstick and ankle were divided into 2 groups,small sapbenous vein deligation in proximal pedicle flap group (group A) (n=38), and proximal small saphenous vein and great saphenous vein or tributaries at recipient site anastomosis flap group (group B) (n=18).METHODS: During sural neurocutaneous island flap retrograde metastasis for repair,(3.5×4.0)cm-(4.0×4.5) cm flap was obtained in 35 cases, and (4.0×4.5) cm -(10.0×12.0) cm in 21 cases.MAIN OUTCOME MEASURES: Outcome of flap survival at different incision area and implanted methods.RESULTS: No vein articulo occurred in 21 cases, which flap areas were (4.0×4.5) cm -(10.0×12.0) cm. Five of 35 cases which flap areas were (3.5×4.0) cm -(4.0×4.5) cm developed vein articulo.The necrotic rate of flaps in group B was significantly lower compared to the group A (P=0.017 67).CONCLUSION: When the area of skin flap is smaller than (4.0×4.5) cm, the proximal end of the small saphenous vein should be anastomosed with the great saphenous vein or tributaries connecting with the great saphenous vein at recipient site.The small saphenous vein is not a superficial vein, which only cross the skin flap, but it has trophic action on the skin flap.

Objective:To explore whether apoptotic ovarian cancer cells induced by chemotherapy drugs paclitaxel and cisplatin can be cross-presented by dendritic cells(DCs) and enhance immune responses.Methods:DCs were induced from peripheral blood monocytes cells by GM-CSF/IL-4 for 6 d,then they were stimulated with either apoptotic ovarian cancer HO8910 cells,frozen-thawed HO8910 cells or control cells for 4 h.Their surface markers and phagocytotic ability were detected by flow cytometry and confocal microscopic scanning assay,respectively.DCs of different groups were cultured with CD8+ T cells isolated by magnetic cell sorting,and the ability of DCs to activate CD8+ T cells was evaluated by 3H-TdR,the activity of CTL to kill tumor cells was evaluated by LDH.Production of IFN-? by CD8+ T cells was measured by ELISPOT.Results:Apoptotic ovarian cancer cells induced by chemotherapy drugs paclitaxel and cisplatin could be phagocytized by DCs,which subsequently promoted the maturation and antigen presenting ability of DCs.Apoptotic ovarian cancer cells implused DCs significantly promoted proliferation of CD8+ T cells compared with that of control cells(P

Objective To investigate the value of intraoperative ultrasound in the resection of hemangioblastoma.Methods Intraoperative ultrasound was applied in 17 patients who underwent resection. The size,number,location ,depth,feeding arteries and draining veins of the tumors were clearly displayed.Results Intraoperative ultrasound could real-time locate the tumor with high accuracy. Totally there were 35 tumors in 17 patients, and intraoperative ultrasound found 32 of them.The diameter of thr smallest tumor was 7 mm. Intraoperative ultrasound could displayed clearly the feeding arteries and draining veins in bigger tumors. Conclusions Intraoperative ultrasound should be routinely used in the operation of hemangioblastoma for its high detection rate.

Three hundred and twenty-one bacteria strains were obtained from rice leaves,stem,root tissue and paddy field soil,of which the number of strains which can inhibit mycelium of Magnaporthe grisea growth markedly was fifty-seven through fermentation in 2.0 mL Eppendorf tube,and among these fifty-seven strains,five strains were strongly antagonistic to Magnaporthe grisea.These five strains was identified for their morphologic,physiological and biochemical characteristics,and the results showed that one strain(No.156)was bacillus subtilis,two strains(No.171 and No.177)were Bacillus pumillus and two strains(No.192 and No.279)were Bacillus ploymyxa.

In the process of vinification, the metabolic products of various yeasts are key to the sensory characteristics. Different species produce different volatile composition, which results in direct influences on wine's bouquet mostly. Metabolic characteristics of Saccharomyces and non-Saccharomyces and the different influences on odour by them as well as interactions among various species were described in this paper. Research progress on non-Saccharomyces was summarized.Studies confirmed that some characteristics of non-Saccharomyces play a positive role in the structure of bouquet of wine. Combined use of Saccharomyces and some of non-Saccharomyces will be beneficial to sensory characteristics of wine.

Objective To explore immunotherapy effective combined with active immunotherapy in different time according rats bearing-tumor after paclitaxel and carboplatin chemotherapy, and to identify the optimization time and strategy of vaccine and seek rational chemo-immunotherapy strategies in ovarian cancer treatment. Methods The dynamic immunocytes number and function in established tumor treated with paclitaxel and carboplatin chemotherapy were investigated. The changes of established tumor volume and immune function of different groups were observed according to combining different time after chemotherapy and vaccine. Results Lymphopenia was observed and the number of lymphocyte subset decreased remarkably on the 6th day, but all cells were found almost recovered on 15th day after chemotherapy. There is the process of immune-enhancing from post-chemotherapy 6 day to 10 day and reversal of immune suppression temporary. The combination post-chemotherapy 6 day with CTL caused a significantly delayed tumor growth in both tumor models and induced significant the proliferation of T lymphocyte by [H] 3 releasing. The number of CD8+T cell is the highest, but the expression of Tr cell was lowest in the group of post-chemotherapy 6 day with CTL. Furthermore, the ability of CD8+T secretion IFN-γ is the most in the post-chemotherapy 6 day with immunotherapy groups. Conclusion Combinational paclitaxel and carboplatin chemotherapy has synergistic effects with active immunotherapy boosting against tumor during window periods, where 6 days after chemotherapy with the most decreased number of lymphocytes in the animal periphery might represent the optimal checkpoint for the immune therapy against tumors. Therefore, monitoring the immune status of tumor patients might become one of the important prerequisites for the effective immune therapy when designing the comprehensive therapeutic strategies.

Objective To explore the differences in health care quality,scale,output,efficiency,cost and financial condition between freestanding secondary hospitals and system-affiliated secondary hospitals in Shanghai,and analyse the determinants of hospital integration. Methods Eleven upper secondary hospitals in Shanghai integrated between 2000 and 2004 were selected,and another 40 secondary hospitals (including 30 upper secondary hospitals and 10 middle secondary hospitals) without integration were served as controls. Using related data of 1999,Mann-Whitney U test was performed to analyse the differences between these two groups,and Logistic regression analysis was conducted to explore the determinants of hospital integration. Results There were significant differences in health care quality,scale,and output between these two groups (P0.05). It was revealed by Logistic regression analysis that health care quality,scale,output,and financial condition were determinants of integration. Conclusion System-affiliated secondary hospitals have advantages over freestanding hospitals in health care quality,scale,output and financial condition,and those with better health care quality,larger scale,larger output and better financial condition are more likely to be integrated by tertiary hospitals.
