Objective To evaluate the expression of IL-6,TGF-β,matrix metalloproteinase-7 (MMP-7) in the peritoneal fluid of different stage of endometriosis (EMs) patients.Methods Peritoneal fluid samples from female without EMs (n =35) and 45 patients with EMs (36 cases with stage Ⅰ,Ⅱ;9 cases with stage Ⅲ,Ⅳ)were obtained for detectionof IL-6,TGF-β,MMP-7byELISA.Results TheconcentrationofIL-6,TGF-β,MMP-7 was (736.5 ± 526.6) ng/L,(936.5 ± 523.5)ng/L and (5.63 ± 1.98) μg/L in EMs patients,which were higher than those in control group (P ＜ 0.01).The concentration of IL-6,MMP-7 was (948.6 ± 485.4) ng/L,(8.69 ± 1.23) μg/L in stage Ⅲ,Ⅳgroup,and (453.6 ± 256.8) rng/L,(4.23 ± 1.08) μg/L in stage Ⅰ,Ⅱ group,there were significant differences between the two groups (P ＜ 0.05).The concentration of MMP-7 was positively correlated with IL-6(r =0.789,P ＜0.01),and was negatively correlated with TGF-β(r =-0.458,P ＜0.05).Conclusion IL-6,TGF-β,MMP-7 may play roles in microecology immune imbalance and the development of EMs.

OBJECTIVE To investigate the genes of disinfectant-sulfadiazine and antibiotic resistance of Escherichia coli strains in elderly wards.METHODS Polymerase chain reaction and dilution test were used to detect and analyze the disinfectant-sulfadizane drug resistance gene and drug resistance of the E.coli.RESULTS From 30 E.coli strains isolated from elderly patients,21 were detected carrying disinfectant-sulfadizine drug resistance genes,and the positive rate of qacE△1-sulⅠ was 70.0%.CONCLUSIONS The detection rate of disinfectant-sulfadiazine drug resistance gene from E.coli strains isolated from elderly patients,the bacteria detection rates are relatively high.Most of the isolates were resistant to commonly used antibiotics.It suggests that clinical drug-resistant strains may be resistant to disinfectants.This condition should be paid much attention by disinfection wotkers of our country.

Objective: To develop a scale to measure attitudes toward homosexuals in Chinese university students.Methods:Based on surveys and literatures, we conducted the pre-test and test for accessing the construct validity of the scale by EFA ( exploratory factor analysis) and CFA (confirmatory factor analysis) in 1010 Chinese university students.Results: There were three components that could explain 63.84% of the total variance with loading between 0.501 and 0.851 in the scale.The three components could explain 46.67%,10.27% and 6.90% of the variance separately.They were named cognitive tolerance, emotional tolerance and behavior tolerance.The scale had NFI 0.979,NNFI 0.981,CFI 0.985,RMSEA 0.073 by CFA.The Cronbach'?coefficient was 0.931 and the test-retest reliability was 0.839 (with P

Objective To investigate the duration for silicon gastric tube to indwell in stomach of aged patients.Methods One hundred elderly patients needing long-term nutrition support were equally randomized into two groups: control group and observation group.The former had the gastric tubes indwelled in the stomach for 4 weeks and the latter for 3 weeks.The two groups were compared about the used tubes in terms of the color of tube at the length of the first 10cm,the indentation by reflection for 10 seconds at the tube of first 10 cm,the hardness of the tube at the length of the first 10 cm and the springback angle of tube at the first 10cm after reflection.Results The tubes in the observation group were significantly better than those in the control group in terms of color,indentation,hardness and springback angle(all P<0?01).Conclusion The duration of indwelling silicon gastric tubes in stomach can be three weeks for old patients needing long-term nutrition support via indwelling silicon tubes in their stomach.

OBJECTIVE To analyze the epidemiological characteristics,the efficiency of the surveillance system for nosocomial infections in our hospital,the sensitivity,specificity and timeliness of case reporting and to evaluate the efficiencies of the monitoring and reporting system.METHODS We reviewed the nosocomial infection reporting data in the year of 2005 and identified all the reported cases,confirmed cases and under-reported cases.Sensitivity and specificity of the reporting system were calculated based on these data.RESULTS The incidence of nosocomial infection was 3.04% in 2005.A majority(72.07%) of the cases were reported within 7 days of occurrence.Respiratory tract infection accounted for 57.75% of all nosocomial infections and was by far the most common site of concern.The rates of false positive reporting ranged from 14-37% and were statistically significantly associated with the sites of the infection(P

OBJECTIVE: To observe the efficacy of allergen blocking nasal spray (ABNS) , combined with seawater spray (SS) and myrtol standardized capsules (MSS), in patients with rhinitis sicca. METHOD: Patients diagnosed as rhinitis sicca were randomly divided into 2 groups: ABNS+SS group and SS group. In ABNS+SS group, patients used ABNS and SS four times per day and MSS twice per day. In SS group, patients used the same medicine except ABNS. Both group were observed for 14 days. The visual analog scale (VAS) of dryness, the endoscopy evaluation score (EES) and the tolerability of the spray were compared between the 2 groups. RESULT: There were 30 patients included in each group. The VAS and EES were improved in both groups after 2 weeks' treatment. The improvement of VAS and EES in ABNS+SS group was significantly superior to SS group (VAS: P < 0.01, EES: P < 0.05). There were only 2 patients complaint of slight discomfort when using ABNS, which did not disturb the treatment. CONCLUSION There is good efficacy of allergen blocking nasal spray (ABNS), combined with seawater spray (SS) and myrtol standardized capsules (MSS), in patients with rhinitis sicca.

Objective To investigate the clinical characteristics of diabetic retinopathy(DR)and diabetic nephropathy(DN)and their correlation. Methods All of 9237 hospitalized type 2 diabetes patients from January 2004 to June 2009 were collected. The prevalence and clinical of characteristics of DR and DN as well as their relationship were analyzed. Results The total prevalence of DR was 33.0%(3045/9237),and the prevalence of DR in the microalbuminuria, macroproteinuria and macroalbuminuria combined with renal dysfunction patients were 36.3%(588/1618),53.7%(1113/2074)and 70.7%(1206/1706)respectively.The prevalence of DN was 58.4%(5398/9237). Compared with that in the diabetes patients without DR, the levels of microalbumin and total protein in the urine were higher in the patients with moderate non-proliferative diabetic retinopathy(NPDR), serious NPDR and proliferative diabetic retinopathy(PDR), but the endogenous creatinine clearance rate was lower(P＜ 0.05). According to the non-conditional Logistic regression model,the risk factors of DR included diabetes duration,urinary protein,fibrinogen, C-reactive protein and peripheral neuropathy, and the risk factors of DN included diabetes duration, HbA1c, systolic blood pressure,urinary protein,low density lipoprotein and DR. Conclusions DR and DN are the chronic microvascular complications in the type 2 diabetes and have higher prevalence. There are good correlations between DR and DN.

Objective To investigate the current status of type 2 diabetic patients who failed to achieve the glycemic control target, and provide theoretic evidences for making corresponding strategies. Methods The 2 diabetic patients who failed to reach the glycemic target were recruited from 181 hospitals in 26 cities and received a standard questionnaire, the conditions of their blood glucose level, lifestyle intervention, blood sugar monitoring, and drug therapy were recorded. Totally 3 861 questionnaires with complete information were collected. And the causes which account for glycemic control status were analyzed. Results Among these patients, the mean HbA1c was 7.9%, the mean fasting plasma glucose was 8.2 mmol/L, and the mean postprandial plasma glucose was 11.5 mmol/L. Only 25.6% of patients take their diet control strictly as prescribed and 44. 5% of patients have little exercise. 35. 8% and 47.8% of patients did not monitor their fasting and postprandial plasma glucose,respectively. Glycemic control in the patients aged ＞ 60 years was similar to the younger patients, but the hypoglycemia incidence in the elder group reached 35.5%, which was higher than those in the other 2 groups (20.8% and 21.4%, both P＜0. 05 ). The proportion of patients with mono-therapy and combination therapy was 46. 1% and 51.7%, while the proportion with combination therapy rose in the patients aged ＞60 years (58.7%;Compared with the other age-groups, all P＜0.05 ). 75 % of patients have adjusted their drug administration regimen since initial treatment. Conclusions Inadequate or inappropriate drug therapy regimen is a major cause responsible for this poor glycemic control status. In addition, the unhealthy life styles, insufficient blood sugar monitoring, and poor compliance were also important causes. Thus, for these patients, it is necessary to further enhance patients' education, to improve life style intervention, as well as to select more effective, safer, and compliant drug therapy regimens. Finally, the glycemic control target for the elder patients should be more flexible.

AIM:To explore the role of sphingosine 1-phosphate (S1P) in the dysfunction of vascular endo-thelial cells exposed to high glucose.METHODS: In human aortic endothelial cells cultured under high-glucose ( 22 mmol/L glucose) medium, nitric oxide ( NO) level, polymorphonuclear neutrophil-endothelial cell adhesion rate, protein level of intercellular adhesion molecule-1 ( ICAM-1) , migration of endothelial cells and Akt/endothelial nitric oxide syn-thase ( eNOS) pathway activation were observed after S1P, sphingosine kinase-1 inhibitor and/or Akt inhibitor treatments. RESULTS:S1P decreased NO level, increased polymorphonuclear neutrophil adhesive rate, enhanced ICAM-1 protein level, and inhibited migration of endothelial cells and activation of Akt/eNOS pathway in endothelial cells cultured under high-glucose condition.Sphingosine kinase-1 inhibitor, which reduced S1P content, significantly improved the above endo-thelial cell function indexes and restored the activation of Akt/eNOS pathway.CONCLUSION: S1P promoted high glu-cose-induced dysfunction of endothelial cells probably by inhibiting the activation of Akt/eNOS signal pathway.Targeting S1P is expected to become one of potential treatment strategies to reduce endothelial cell dysfunction.

OBJECTIVE To investigated the impact of age,sex and season on the morbidity of allergic rhinitis(AR)and noninfectious,nonallergic rhinitis(NINA).METHODS The clinical data of the patients with AR and NINA was analyzed from Oct.2003 to Oct.2005.Factors such as age,sex, etc were taken into consideration.RESULTS The highest morbidity age of AR was 10～19 years, and that of NINA was 30～39 years.The morbidity of allergic rhinitis in men was higher than that in women before 20 years old,while there was no sexual difference of nonallergic rhinitis.About 61.6% of patients diagnosed with AR developed their condition before 20 years old,about 66.5% of patients diagnosed with NINA developed their condition after 20 years old.The number of patients with AR increased markedly from July to November, while there was no seasonal diversity of NINA. CONCLUSION There were obviously differences between AR and NINA of age,sex and seasons, which implied different pathologic mechanism between these two types.
