Objective To explore the features of transsphenoidal microsurgical treatment of male pro- lactinoma and to evaluate the sexual function before and after transsphenoidal microsurgery.Methods A se- ries of 23 cases male prolactinoma were analysed combined with retrospective and prospective study.9 casese with sexual disfunction had finished the International Index of Erectile Function with 15-item questionnnaire (ⅡEF-15) before and after the surgery.Results 8/10 cases treated with dopaminergic agonist combined with surgery achieved complete remission,while only 4/13 cases achieved complete remission with surgery on- ly(x~2=5.490,P=0.036).Aecoding toⅡEF-15,sexual function improved after surgery in 9 cases(paired- sample) t test,P＜0.05).Conclusion Transsphenoidal microsurgical treatment of prolactinoma may im- prove the male sexual functions.Dopaminergic agonist combined transsphenoidal microsurgery may achieve a better outcome.

Objective To study the inhibitory effects of dendritic cells modified by sCD41)gene on T lymphocytes phenotypes and cytokines production and the mechanism of inducing donor-specific immune tolerance in vitro.Methods T lymphocytes prepared with Nylon Fiber Column from Balb/c mice(as reaction cells)and DCs of different groups(as stimulation cells)were subjected to primary mixed lymphocyte culture(MLC).After incubation for 7 days,the responsiveness of the cells was de- tected by MTS method at the indicated time points,and supernatants were assayed for IFN-?,IL-2, IL-4,IL-10 by ELISA kits.On the day 5,the cultured cells were assessed for the expression of CD4, CDS,CD25 and CD69 by using flow cytometry(FCM).After secondary MLC for 5 days,the same indexes were assayed hy using the same methods.Results Dendritic cells modified by sCD40 could in- duce the hyporesponsiveness to alloantigen in primary and secondary MLC.In primary MLC,the ex- pression of CD4~+ and CD8~+ T cells and CD4~+ CD25~+,CD8~+ CD25~+,CD4~+ CD69~+,CD8~+ CD69~+ T cells in IX;modified by sCD40 group were less than those in control group(P

Armillariella tabescens EJLY2098 was induced to produce ?-mannanase with konjac fine flour (Amorphopallus rivieri) as single carbon source. This induced enzyme was then purified using DEAE ion exchange chromatography and named atMAN47. Zymologic analysis showed that the molecular weight of this ?-mannanase was approximately 47 kD. The enzyme was stable when pH ranged from 5.0 to 6.5 and could be activated by Na+ and Ba2+. With an optimal temperature of 50?C. Action mode analysis of TLC revealed that the enzyme belonged to the endo-?-mannanase family. Being a meta-acid endo-?-mannanase, it was suitable to be applied to feed industry with a promising future as an enzyme preparation.

Objective To investigate the feasibility, effect and mechanism of chemical bile duct embolization for chemical hepatectomy. Methods Phenol or absolute ethanol plus cyanonacrylate were employed as embolization agents. Histology, Fas and TGF-? 1 measurement were used to evaluate the result. Results Phenol plus cyanonacrylate effectively destroyed and embolized intrahepatic biliary duct, leading to complete disappearance of hepatocytes in the periphery of embolization lobe and thereby achieving the effect of chemical hepatectomy. Expression of Fas and TGF-? 1 in phenol embolism group (88.90?38.10, 185.22?70.39) and ethanol embolism group (72.39?29.51, 163.56?51.75) were higher than those in biliary duct ligated group (26.31?12.07, 74.84?40.73) ( P

Objective To investigate the immunological activity change of regulatory T cells (Treg) and discuss its significance in the outcomes of patients with multiple organ dysfunction syndrome (MODS) and severe burn. Methods A total of 106 patients with total burn surface area (TBSA) larger than 30% were included in the study and randomly divided into three groups according to the burn area: Group Ⅰ (TBSA of 30%-49%, n = 41), Group Ⅱ (TBSA of 50% -69%, n = 34) and Group Ⅲ (TBSA of 70%-99%, n = 31). According to the development of MODS, patients were divided into MODS group (n =21) and non-MODS group (n =85). The patients with MODS were further divided into non-survival group (n = 16) and survival group (n = 5) based on their outcomes. Healthy volunteers were served as normal control (n = 25). Peripheral blood samples were collected at days 1,3,7, 14 and 21 postburn. The immunomagnetic separation technique was applied to separate and purify CD4+ CD25+Tregs in peripheral blood, and phenotypes (CTLA-4) were analyzed by flow cytometry and the contents of interleukin-10 released in the supernatants were determined by ELISA. Results Expression of CTLA-4 and level of IL-10 were significantly increased in burn patients compared with normal control group, with statistical differences. The expression of CTLA-4 and level of IL-10 were significantly increased in patients with severe burns at all time points. The expression of CTLA-4 and level of IL-10 in MODS group were much higher than those in non-MODS group at days 3-21 postburn (P ＜ 0.01). Among the MODS patients, the expression of CTLA-4 and level of IL-10 in the survival group were obviously lower than those in the non-survival group at days 3-21 postburn (P ＜ 0.05 or P ＜ 0.01). Conclusions After severe burn injury, expressions of the markers on CD4 + CD25 + Treg surface and secretion of cytokines produced by CD4 + CD25 + Tregs show significant difference in patients with different born areas, MODS development and survival state. CD4 + CD25 + Treg may play an important role in the pathogenesis of immunoregulation, MODS and mortality of burn patients through secretion of inhibitory cytokines.

Objective To explore the effect of different processing and drying methods of corn and hot pepper on fluorine content in coal-burning type of the endemic fluorosis areas, and to screen food processing and drying methods which meet the quality requirements of grain drying and able to effectively reduce the total fluoride intake of local population. Methods Farmers of endemic fluorosis area in Bijie, Guizhou province were divided into 3 groups: sun-baked drying group, stove drying group with air-tight cover and stove drying group with no cover, 10 households in each group. Corn and fresh hot pepper and samples dried for 2 weeks, or 1, 3, 6-month were collected, and water and fluoride content were detected, and the total daily fluoride intake were calculated in accordance with the "Determination of Water in Food" (GB/T 5009.3-2003) and "Determination of Fluorine in Foods"(GB/T 5009.18-2003). Results Fluoride content in fresh corn and dried for 2 weeks, or 1, 3, 6-month [of sunbaked drying group: (1.40 ± 0.16), (1.56 ± 0.14), (2.15 ± 0.47), (2.70 ± 0.64), (4.06 ± 1.75)mg/kg, stove drying group with air-tight cover: (1.41 ± 0.16), (2.39 ± 0.56), (4.60 ± 0.97), (8.46 ± 5.55), (11.36 ± 3.60)mg/kg,stove drying group with no cover: (1.40 ± 0.13), (4.69 ± 3.97), (4.47 ± 2.77), (9.65 ± 6.47), (26.12 ± 14.52)mg/kg] and pepper[sun-baked drying group: (5.41 ± 1.61), (16.60 ± 7.62), (32.60 ± 7.88), (50.26 ± 17.60),(240.20 ± 272.49)mg/kg, stove drying group with air-tight cover: (754 ± 2.95), (3238 ± 11.50), (119.18 ± 156.45),(224.00 ± 196.58), (495.70 ± 417.29)mg/kg, stove drying group with no cover: (4.82 ± 1.25), (44.30 ± 13.48),(122.89 ± 66.43), (334.23 ± 166.05), (531.01 ± 397.40)mg/kg] increased with elongation of drying time, and the group difference was significant(F = 44.77, 128.71, 126.87, 41.61, 53.63, 170.63, all P ＜ 0.05), with the largest rate of increase in stove drying group with no cover, and the lowest in sun-baked drying group;fluoride was significantly lower (t = 7.93,63.07,5.36,11.98,55.76,7.45, all P ＜ 0.05) after sample washing;total fluoride intake per person per day was 2.57 mg in local adult when ate washed and sun-baked corn, peppers, the total fluoride intake were 5.92, 8.14 mg when ate the food processed by other two drying methods and washed corn, peppers,respectively. Conclusions In the coal-burning type of fluorosis endemic area, should take appropriate health education measures, and instruct local residents to use sun bake their edible corn and pepper for human consumption, and cultivate a habit of washing corn and pepper before cooking, which can reduce the population total fluoride intake, and control endemic fluorosis.
