Objective To study the qualitative analysis and quantitative analysis of flavonoids and other ingredients in leaves of Lonicera hypoglauca miq,and to optimize the reflux extraction condition for total flavonoids from leaves of lonicera hypoglauca miq. Methods Preliminary test was used for qualitative analysis. UV-spectrophotometry was used to determinate content of total flavonoids. By orthogonal design,the extraction rate of flavonoids was determined in different factors of ethanol reflux extracting. Results Leaves of lonicera hypoglauca miq contained alkaloids and flavonoids.The optimum conditions of ethanol reflux extracting total flavonoids are 12 times 50% ethanol,and refluence for 1.0h at water bath for two times.According to validate experiment,the average total flavonoids content was 16.6% in leaves of lonicera hypoglauca miq,with RSD=1.52%(n=3). Conclusion Flavonoids are in higher level in leaves of Lonicera hypoglauca miq. There are some chemical similarity in leaves of lonicera hypoglauca miq and leaves of flos lonicerae.

Objective To observe the effect of arthroscopic meniscectomy to tr eat discoid lateral meniscus tear. Methods From July 1999 to June 2003, arthrosc opic meniscectomy was conducted for 49 menisci of 45 patients with discoid later al meniscus tear. 41 patients had unilateral injury, and 4 bilateral. 32 knees w ere complete injury and 17 incomplete. The discoid lateral meniscus tear account ed for nearly one third of the patients with meniscus tear who received arthrosc opic meniscectomy at the same time. Arthroscopic partial meniscectomy was done f or 44 knees, total meniscectomy for 5 knees and meniscus suture for 3 knees. Aft er operation the rehabilitation training programs, including straight-leg-rais ing exercise and range-of-motion exercise, were carried out. Results The opera tions for the 45 cases were successful and there was no complication. 40 patient s were followed up. Before operation, the mean Lysholm -Ⅱscore was 55 points ( 40 to 71 points). After a mean follow-up period of 39 months, the mean Lysholm -Ⅱscore was 88 points (60 to 100 points). The excellent and good results were obtained in 85.3%of the patients. Conclusions Arthroscopic meniscectomy should be a preferred method for discoid lateral menisci tear, due to its minimal invas ion, possibility of early mobilization, a lower complication rate, and preservat ion of more meniscus structure and function. If the operation is combined with s tandard rehabilitation training, the effects can be enhanced.

Objective To investigate the infection situation of Pseudomonas aeruginosa (PA) in patients with the lower respira‐tory tract infection in the department of respiratory intensive care units (RICU ) in recent five years ,and to analyze the changing trend of antibacterial resistence ,in order to guide rational selection of antimicrobial agents .Methods Strains of bacteria were isola‐ted and identified from sputum specimen of patients in the department of RICU and common ward from Jul .2008 to Jul .2013 .The situations of PA infection and antibacterial resistence were analyzed ,and differences of infection rates of PA and antibacterial resis‐tence were compared between RICU and common ward .Results 517 strains of bacteria were detected from sputum specimens of patients in the department of RICU from 2008 to 2013 ,including 141 strains of PA (accounted for 27 .3% ) ,and ticarcilli/clavulanic acid(61 .0% ) was with the highest rate of resistance among 14 drugs and colistin B(9 .2% ) was with the lowest rate of resistance . 378 strains of bacterias were detected from sputum specimens of patients in common wards ,including 125 strians of PA(accounted for 33 .1% ) ,and ticarcilli/clavulanic acid(28 .0% ) was with the highest rates of resistance and colistin B (4 .0% ) was with the low‐est rate of resistance .Conclusion In recent 5 years ,PA might be one of the main pathogenic bacterias of respiratory tract infections in the depatment of RICU in this hospital ,and antibiotic resistance may increse gradually .The antibiotic resistance in the depatment of RICU may be higher than that in cionmon wards .Clinical effective measures should be taken to prevent nosocomial infection ,and rational use of antibiotics should be taken to reduce the emergence of resistant strains .

Objective:To investigate the role of TSLP and NF-κB in the pathogenesis of adenomyosis.Methods:Immunohisto-chemistry was employed to detect the expression of TSLP and NF-κB p65 in the endometrial glandular cell and stromal cell of 35 adeno-myosis patients and 20 hysteromyoma patients as control , and analyze the correlation of the two proteins.The concentration of TSLP was measured by specific ELISA in the serum of healthy subjects besides of the patients with adenomyosis and hysteromyoma .Results:TSLP and NF-κB p65 were both positively expressd in the glandular cells and stromal cells of ectopic and eutopic endometrium of patients with adenomyosis , their expression was significantly higher than that of the control group ( P<0.01 ) , and the expression of TSLP and NF-κB p65 in ectopic endometrium was significantly higher than that in eutopic endometrium ( P<0.01 ).There was positive correlation between TSLP and NF-κB p65 in ectopic endometrium.The concentration of TSLP was higher in the serum of patients with adenomyosis.Conclusion:The TSLP is highly expressed in endometrial glandular and stromal cells of patients with adenomyosis , and there is higher level of TSLP in serum , and there is correlation between the expression of TSLP and NF-κB in ectopic endometrium.

Objective To investigate the relationship between the CD+4 CDHigh25 regulatory T cells and cytokine IL-10 and acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods Flow cytometric was used to detect the percentage of CD+4 CDHigh25Foxp3High Treg cell and CD+4 CDHigh25 CDLow127 Treg cell in CD+4 T cells and at the same time ELISA was used to test the serum IL-10 levels in corresponding period. Results 13 patients have received hematopoietic function reconstruction. aGVHD group of CD+4 CDHigh25 CDLow127/CD+4 and CD+4 CDHigh25 Foxp3High/CD+4 ratio were significantly lower than non-aGVHD group, the difference was statistically significant (P ＜0.01); Ⅲ-Ⅳ degree of aGVHD subgroup was lower than Ⅰ - Ⅱ degree of aGVHD subgroup, but no statistical significance(P ＞0.05); the same as between-group CD+4 CDHigh25 CDLow127/CD+4 and the CD+4 CDHigh25 Foxp3High/CD+4 has no significant difference;aGVHD group of IL-10 concentration was significantly lower than non-GVHD group, the difference was statistically significant (P ＜0.01). Treg cell and IL-10 changes in correlation, r = 0.557, P ＜0.05. Conclusion The level of Treg cell was closely related to the occurrence of aGVHD after allo-HSCT. So it is very important to monitor the Treg cell level for clinical early diagnosis of aGVHD and predict prognosis of aGVHD and guide the application of immunosuppressant. CD127 can serve as a Treg cell surface-specific marker, to promote the detection of Treg cell and purification. IL-10 was an important negative regulator. Treg cell and IL-10expression in patients with aGVHD was correlation, which may provide some basis for Treg cell immunosuppressive mechanism.
