Objective To investigate the expression of micro RNA-146a (miR-146a),TNF receptorassociated factor 6 (TRAF6) gene and IL-1 receptor-associated kinase 1 (IRAK1) gene in the peripheral mononuclear cells (PBMCs) of patients with ankylosing spondylitis (AS) and their relationship with the disease activity.The role of miR-146a,TRAF6,IRAK1 in the pathogenesis of AS was explored.Methods Expression of miR-146a,TRAF-6 and IRAK-1 in peripheral blood mononuclear cells was studied using realtime polymerase chain reaction (qRT-PCR) in 45 AS patients and 22 healthy controls.The indicators of disease activity adopted in this study were Bath ankylosing spondylitis disease activity index (BASDAI),erythrocyte sedimentation rate (ESR),C-reactive protein (CRP) level,and immunoglobulin (Ig).The relationship was analyzed in AS patients between the relative expression levels miR-146a,TRAF6,IRAK1 and BASDAI,ESR,CRP,Ig concentration.Non-parametric test,t test,One-way ANOVA,Pearson's and Spearman's correlation analysis were used for statistical analysis.Results ①The relative expression level of miR-146a which was observed in PBMCs of AS patients was significantly higher than that in normal control group [1.46(0.39,4.79)and 0.81(0.17,1.90),P＜0.05].The expression of miR-146a was significantly higher in active AS patients group than that in inactive patients [2.93(0.95,7.95) and 0.54(0.28,1.69),P＜0.05],there was no difference between the treatment group and without treatment group [1.28(0.31,2.37) and 2.22(0.49,7.71),P＞0.05].② There was significant difference in the relative expression level of IRAK-1 between AS patients and the normal control group.IRAK1 was significantly higher in AS patients than that in normal control group (1.4±0.7,1.1±0.4,P＜0.05).However,there was not difference between active AS patients group and inactive patients group as well as treated group and untreated group (1.5±0.9,1.4±0.5; 1.6±0.7,1.3±0.7,P＞0.05).③ TRAF6 expression was obviously lower in AS patients than that in normal control group (1.3±0.6,1.7±0.8,P＜0.05),and that was also significantly lower in the untreated group and active group than that in the normal control group (1.1±0.7,1.7±0.8; 1.1±0.5,1.7±0.8,P＜0.05).④ Signi-ficant positive correlation was observed between the miR-146a level and BASDAI,as well as duration of morning stiffness (r=0.557,P=0.000; r=0.363,P=0.018).The expression level of IRAK1 was significantly negative correlated with IgM (r=-0.313,P=0.046).Conclusion ① miR-146a expression is up-regulated in patients with AS,and it may be a potential useful marker for disease activity in AS patients; ② The abnormal expression of IRAK1,TRAF6 in AS patients may play a role in the pathogenesis of AS.

BACKGROUND: Increased extravascular lung water (EVLW) in shock is common in the critically ill patients. This study aimed to explore the effect of cardiac output (CO) on EVLW and its relevant influence on prognosis. METHODS: The hemodynamic data of 428 patients with pulse-indicated continuous CO catheterization from Department of Critical Care Medicine, Peking Union Medical College Hospital were retrospectively collected and analyzed. The patients were assigned to acute respiratory distress syndrome group, cardiogenic shock group, septic shock group, and combined shock (cardiogenic and septic) group according to their symptoms. Information on 28-day mortality and renal function was also collected. RESULTS: The CO and EVLW index (EVLWI) in the cardiogenic and combined shock groups were lower than those in the other groups (acute respiratory distress syndrome group vs. cardiogenic shock group vs. septic shock group vs. combined shock group: CO, 5.1 [4.0, 6.2] vs. 4.7 [4.0, 5.7] vs. 5.5 [4.3, 6.7] vs. 4.6 [3.5, 5.7] at 0 to 24 h, P = 0.009; 4.6 [3.8, 5.6] vs. 4.8 [4.1, 5.7] vs. 5.3 [4.4, 6.5] vs. 4.5 [3.8, 5.3] at 24 to 48 h, P = 0.048; 4.5 [4.1, 5.4] vs. 4.8 [3.8, 5.5] vs. 5.3 [4.0, 6.4] vs. 4.0 [3.2, 5.4] at 48 to 72 h, P = 0.006; EVLWI, 11.4 [8.7, 19.1] vs. 7.9 [6.6, 10.0] vs. 8.8 [7.4, 11.0] vs. 8.2 [6.7, 11.3] at 0 to 24 h, P < 0.001; 11.8 [7.7, 17.2] vs. 7.8 [6.3, 10.2] vs. 8.7 [6.6, 12.2] vs. 8.0 [6.6, 11.1] at 24 to 48 h, P < 0.001; and 11.3 [7.7, 18.7] vs. 7.5 [6.3, 10.0] vs. 8.8 [6.3, 12.2] vs. 8.4 [6.4, 11.2] at 48 to 72 h, P < 0.001. The trend of the EVLWI in the septic shock group was higher than that in the cardiogenic shock group (P < 0.05). Moreover, there existed some difference in the pulmonary vascular permeability index among the cardiogenic shock group, the septic shock group, and the combined shock group, without statistical significance (P > 0.05). In addition, there was no significant difference in tissue perfusion or renal function among the four groups during the observation period (P > 0.05). However, the cardiogenic shock group had a higher 28-day survival rate than the other three groups [log rank (Mantel-Cox) = 31.169, P < 0.001]. CONCLUSION Tissue-aimed lower CO could reduce the EVLWI and achieve a better prognosis.

Different factors including hybridization solution components, hybridization temperature, and the concentration and proportion of the labelled primer, which affected the sensitivity and specificity of single mutation identification, were exploited. Asymmetric PCR increased the hybridization sensitivity, and the asymmetric multi-PCR did not affect the specificity, while the sensitivity was improved a little. Among 30 lung cancer samples detected with the oligonucleotide microarray, 12 was found P53 gene mutations and 5 had K-ras gene mutations. The P53 gene mutations identified by the oligonucleotide microarray was proved 80% same as the sequencing results. The obvious statistical relations of K-ras and P53 gene mutations with tumor type, tumor stage and smoking were not obtained because of less samples and mutation sites.

OBJECTIVETo evaluate the clinical practice of laparoscopic rectopexy in the treatment of severe rectal prolapse.

METHODSFrom March 1998 to February 2007, 4 cases of complete rectal prolapse, including 1 male and 3 female,ranged 21-82 years old, were treated by laparoscopic rectopexy. In one case, the posterior wall of rectum was freed and elevated, and pre-rectal introcession was closed by silk suture, then the posterior wall was suspended and fixed on sacral promontory fascia, finally the sigmoid colon was fixed by sutures on the fascia of left psoas major. In other three cases, insertion of mesh was performed. Rectum was freed and elevated to the level of levalor ani. A sheet of T-shape polypropylene mesh was placed posterior to the rectum, whose lower margin was at the level of levator ani and wrapped around the rectum covering except the anterior wall. The free margin of the mesh was sutured on the muscular layer of rectum, then the mesh was put posterior to the rectum and fixed on the sacral promontory fascia by clipping to repair hernia. After that, the pelvic peritoneum was closed, and finally the sigmoid colon was fixed by sutures on the fascia of left psoas major.

RESULTSFour operation procedures were completed successfully. There was no conversion operation. The time was consumed 92.5 (80-100) min, and the bleeding amount was 6.5 (5-10) ml. No post-operative complications were found. Urine incontinence and encopresis were relieved. No recurrence and constipation was found after 2 months to 3 years follow up postoperatively.

CONCLUSIONLaparoscopic rectopexy is a safe, workable and effective procedure, which can reduce operative trauma and shorten hospitalization time.

OBJECTIVETo study the effect of multiglycosides of Tripterygium wilfordii (MTW) for treatment of proteinuria in kidney transplant recipients.

METHODForty-five kidney transplant recipients with proternuria were randomized into 3 groups (n=15) and received full daily dose (1 mg/kg) MTW, half dose (0.5 mg/kg) MTW or no MTW (control) in addition to immunosuppressant therapy. The 24-hour urinary protein (24 h Upro), blood urea nitrogen (BUN), serum creatinine (Scr), dose of ciclosporin and the adverse effects of MTW were recorded.

RESULTSMTW at both the full dose and half dose significantly reduced the 24 h Upro as compared to exclusive immunosuppressant therapy (P<0.05). The therapeutic dose of ciclosporin in patients with full and half dose of MTW was significantly lower than that in the control group (P<0.05), and the patients receiving full dose MTW showed greater adverse effects than those having half dose MTW (P<0.05).

CONCLUSIONSMTW can significantly ameliorate proteinuria, reduce the therapeutic dose of ciclosporin and protect the renal function in kidney transplant recipients. While producing similar therapeutic effect to routine full dose, long-term use of half dose MTW may reduce the adverse effect associated with MTW.

OBJECTIVETo study the alteration of thymus matrix lymphocyte generator (TSLP) and change of the Th factor in the course of disease development, and to analyze the curative effect of inhalation of Vitamin A (VA) with corticosteroid for the treatment of asthmatic pneumonia.

METHODSAsthmatic pneumonia models were prepared by challenging rats with inhalation of ovalbumin for 4 weeks, and rested for 1 week. The treatment with VA and corticosteroid inhalation for 1 week was followed. The rat thymus and lung specimen were examen by histochemical and immunofluorescence staining.

RESULTSAfter 4 - 5 weeks of stimulation, there were more TSLP-positive cells and alveolar macrophages (AM) found in thymus and lung tissue of asthmatic group, the cell proliferation in spleen and thymus was obvious, and blood Th factors elevated. The inflammation within the lung tissue aggravated gradually. In VA group, the expression of TSLP and Th2 factors were all lowered at the 4th week. The TSLP expression slightly increased at the 5th week, and the cell proliferation within T-cell zone of spleen and thymus was strong at first and weakened later. Alveolar microphages (AM) increased significantly and the inflammation in the lung subsided gradually at the 5th week. In the hormone group, TSLP and Th2 factors expression in both thymus and lung were decreased at the 5th week, while the cell proliferation in thymus and lung was gradually increased. The quantity of AM was decreased, whereas the inflammation of the lung was increased gradually at the 5th week.

CONCLUSIONDuring asthmatic period elevated TSLP expression was accompanied by Th2 type responses while VA and corticosteroid both suppressed TSLP and Th2 factors expression. VA alone promoted T lymphocyte proliferation as well as the antigen elimination function by AM, after ceasing the usage, the lung inflammation abated gradually. In contrast, after ceasing the use of corticosteroid, inflammation aggravated.

OBJECTIVETo improve evidence-based care in the management of tuberculosis, we retrospectively analyzed the bacterial types and drug sensitivity test results of mycobacteria in Guangzhou over the past twelve years (from July 1998 to March 2010).

METHODSOver these twelve years, a total of 14 095 mycobacterial strains isolated from different samples were subjected to type identification and drug sensitivity tests according to the Standard Protocols of Laboratory Diagnostics for Tuberculosis by the Chinese Antituberculosis Association. Chi-square test was performed for statistical analyses for comparisons between groups.

RESULTSOf 14 095 strains of mycobacteria isolated, 10 844 strains (76.84%) were MTB, and 3251 strains (23.16%) were non-tuberculosis mycobacteria (NTM). Compared with the result of the fourth national survey of tuberculosis epidemiology, which showed 11.1% of NTM, the one of our study was significantly different (χ(2) = 69.79, P < 0.001). Drug sensitivity tests of MTB showed tolerance rates of 28.99% (2729/9413), 21.75% (2047/9413), 17.45% (1643/9413) and 11.53% (1085/9413) against isoniazid, rifampin, streptomycin and ethambutol, respectively.

CONCLUSIONAn increasing trend was observed in MTB drug tolerance against streptomycin, rifampin and isoniazid, whereas more and more NTM strains were isolated in recent years. These findings are worthy of note for clinicians.

Objective To explore the management of endocrine disturbance related to Symptomatic Rathke's cleft cysts (RCCs) in both pre- and post-operation, as well as the risk factors for the recurrence of RCCs after the operation. Methods The clinical manifestations, radiological and pathologic features, treatment, and surgical outcomes of 11 cases of symptomatic RCCs were reviewed retrospectively. Results Headache recovered in 100% of patients and visual disturbance improved in 83.3%, and Amenorrhea and/or galactorrhea recovered or improved in 66.7% of patients. However, diabetes insipidus and panhypopituitarism did not improve postoperatively. Transcranial surgery was performed in 6 patients and transsphenoidal surgery in 5 patients. No recurrence occurred in transcranial radical resected cases while 2 of 5 subtotally removed cases recurred with an average follow-up of 34.5 months. Inflammation was present in two of the recurrent cases. Conclusion RCCs is a rare pathology with a wide specctrum of clinical and radiological features. Accurate preoperative diagnosis can be difficult. Endocrine disturbance should be evaluated both pre- and post-operatively, and proper hormones replacement therapy is mandatory in these selected patients, Removing as much as possible and multiple biopsies around the cyst wall will be helpful in accurate diagnosis, especially of cases showing atypical pathologic findings, and special attention should be paid to follow-up examination.

OBJECTIVEIn order to investigate the positive rate of streptococcus suis type 2 and the genes of their suilysin (sly), extracellular protein (epf) and muramidasa-released protein ( mrp) and to understand the antibiotic susceptibility of S. suis type 2.

METHODSS. suis type 2, isolated from slaughtered healthy pig's tonsil in 10 county area of Guangxi, were identified by Multiplex PCR, and the genes of their sly, epf, mrp and the antimicrobial sensitivity analysis were performed.

RESULTS1105 strains of Streptococcus including 667 strains of S. suis and 33 strains of S. suis type 2 were detected from 1179 samples. In these S. suis type 2 strains, there were 22 strains of sly + mrp + epf+ type,1 strain of sly + mrp + epf - type, 2 strains of sly - mrp + epf + type, 7 strains of sly - mrp + epf - type and 1 strain of sly - mrp - epf- type. When these strains were subjected to be tested with penicillin, eritrocina, vacocin, gentamycin, specti-nomysin, enraxacin, ciprofloxaxin, cephalothin VI, sulfadiazine sodium, cyantin, mycifradin, amikacin and achromcin, some were found to be resistant to but most strains were susceptible to cephalothin VI, penicillin and enraxacin. There were 31, 29 and 27 strains over medium sensitivity, respectively, but 28 and 27 resistant strains to amikacin and achromcin were found.

CONCLUSIONThe positive rate of S. suis type 2 in clinical healthy pigs was low (2.8%) and did not show obvious difference between the counties with or without a history of S. suis infection. All the isolated strains were susceptible to cephalothin VI, but most strains were virulent.
