Objective To investigate the prevalence,related factors and individualized health management strategy of female urinary incontinence.Methods Questionnaire survey has been adopted on 4105 female subjects in the east coastal,middle and southwest areas of Shandong Province from Jan.2011 to Dec.2011.Logistic regression model was used to analyze the influencing factors of urinary incontinence.The degree of risk was conducted according to the UI affected to the quality of life.Results The available questionnaires were 4105.Logistic analysis showed that age,delivery frequency,first delivery age,newborn birth weight,perineum injury history,chronic cough and constipation were risk factors of urinary incontinence.However,the protective factors of urinary incontinence included abdominal delivery and whitecollar worker.Mild,moderate and strong impacts of urinary incontinence on the quality of life were found 77.68％ (1079/1389),21.38％ (297/1389) and 0.94％ (13/1389) of the participants,respectively.Unfortunately,doctor's office visiting was as low as 1.08％ (15/1389).Along with the increase of age,parity,age of first time delivery,injury of perineum,chronic cough,constipation,may add the risk of incidence of urinary incontinence while caesarean section and brainwork may decrease the risk of incidence of urinary incontinence.Conclusions The overall of incidence of urinary incontinence in Shandong province is in a high level.Urinary incontinence may significantly reduce the quality of life of the patients.More investigation on individualized health management strategy for female patients with urinary incontinence should be needed in the future.

Objective To explore effects of fosinopril and losartan on renal Klotho expression and oxidative stress in spontaneously hypertensive rats (SHR) and the mechanisms underlying the protection against renal damage. Methods Fifteen male SHRs (22 weeks old) were randomly divided into 3 groups (n=5 in each group): a SHR group, a fosinopril group ［10 mg/(kg?d)］, and a losartan group ［50 mg/(kg?d)］. Age-matched Wistar-Kyoto (WKY) rats were chosen for a control group. Eight weeks later, tail arterial pressure, 24 hours urinary protein (Upro)，urinary N-acetyl-β-D-glucosaminidase (NAGase) were measured. Renal pathological changes were examined under light microscopy by HE staining. The renal mRNA and protein expression of Klotho were determined by RT-PCR, immunohistochemical staining or Western blot. The levels of total antioxidant capacity (TAOC), malondialdehyde (MDA), Cu/Zn superoxide dismutase (Cu/Zn-SOD), Mn superoxide dismutase (Mn-SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) were determined.Results The typical pathological characteristics of hypertensive renal damage were observed in the kidney of the SHR group．Compared with the SHR group, the systolic pressure, Upro, and urinary NAGase, the content of MDA and renal pathological damage was reduced while the renal Klotho expression and activities of TAOC, Cu/Zn-SOD, CAT, and GSH-Px were increased (P<0.05 or P<0.01) in the fosinopril or losartan group. There was no significant difference in renal Mn-SOD level among the 4 groups (P>0.05). Conclusion Fosinopril and losartan can exert protection against hypertensive renal damage through upregulating Klotho expression as well as reducing oxidative stress.

Objective To investigate the clinicopathologic characteristics of premalignant and malignant endometrial polyps (EP) in premenopausal and postmenopausal women.Methods A retrospective analysis was conducted in 42 cases of premalignant and malignant EP from 1993 to 2012.Polyps were classified into premenopausal (group A,10 cases) and menopausal (group B,32 cases),including 26 cases of endometrioid adenocarcinoma,4 of clear cell carcinoma,9 of serous adenocarcinoma,and 3 of atypical hyperplasia.Results The prevalence rate of premalignant and malignant EP was 1.42％ (42/2 965),the prevalence rate of malignancy in postmenopausal and postmenopausal women was 0.48％ (10/2 064) and 3.55％ (32/901),respectively.The mean size of EP was (1.6 ± 0.8) cm,abnormal uterine bleeding was positive in 90％ (38/42) of cases.The EP pathological diagnosis showed all were endometrioid adenocarcinoma in group A,while there were 4 of clear cell carcinoma,9 of serous adenocarcinoma in group B.The mean size of EP was (1.1 ± 0.6) and (1.7 ± 0.9) cm in group A and B respectively (P ＜0.05).According to immunohistochemistry,all cases of group A were ER positive,but 41％ (11/27) of group B were ER negative (P =0.059).The PR positive rate was 8/9 and 56％ (15/27) in group A and B,respectively (P =0.169).Conclusions The risk of the EP malignancy rate is higher,while ER,PR positive rate are lower in postmenopausal womcn.Postmenopausal EP,especially accompanied by abnormal uterine bleeding and large polyps should be removed as soon as possible.

Conclusions The expression of plasma miR-22 was significantly decreased in IPAH patients,and it could serve as a potential biomarker for diagnosis.The miR-22 might be involved in the pathogenesis of the disease through promoting its target gene MYCBP to activate the c-Myc pathway.

ObjectiveTo evaluate the effect of auscultation, partial pressure of carbon dioxide in end-expiration (PETCO2), transillumination technique to judge whether the endotracheal tube is misplaced into the esophagus. Methods A blinded randomized controlled trial was conducted. Sixty patients with American Society of Anesthesiology (ASA) gradeⅠ-Ⅱundergoing endotracheal intubation in Fengxian Central Hospital admitted from September 2014 to February 2015 were enrolled. Two endotracheal tubes with the same size were respectively inserted into the trachea and esophagus for the same depth after general anesthesia by the same person. Two blinded anesthetists with different experience checked the tube position using three methods including auscultation, PETCO2, and transillumination technique, respectively. The order of the tubes tested (trachea or esophagus) and the method used were randomized according to randomise numbers table. The experienced anesthetists conducted the test first, followed by an inexperienced anesthetist conducting the same methods. The numbers of right and wrong determinations with different methods by different anesthetists were recorded.Results Sixty patients underwent the procedures for 180 times, with intratracheal intubation for 90 times, and esophageal intubation for 90 times. It was shown that the results were not different in two groups [96.7% (174/180) vs. 92.2% (166/180),χ2 = 3.500,P = 0.057]. By using auscultation, the correct rate of experienced anesthetist was higher than that of inexperienced (95.0% vs. 78.3%,χ2 = 5.786,P = 0.013). Using PETCO2, both anesthetists were correct in all cases, and the accuracy was 100%. Using transillumination, the experienced anesthetist was mistaken in 3 cases (accuracy was 95.0%), while the inexperienced mistook in 1 case (accuracy was 98.3%), and no significant difference was found between two groups (χ2 = 0.500,P = 0.250). The correct rate of using transilluminaion was significantly higher than that of using auscultation (χ2 = 7.563,P = 0.004). The sensitivity and specificity of the auscultation was 70.0% and 80.0%, that of transillumination technique was 96.7% and 93.3%,and PETCO2 was 100%, respectively, for two groups.ConclusionsPETCO2 is the most reliable method for determining tube position, and it is superior to auscultation and transilluminaion. Transillumintaion technique is superior to auscultation, irrespective of anesthetists' experience, while the accuracy of auscultation showed an obvious relationship with the anesthetists' experience.

Objective To explore the expression of TLR4/NF-κB pathway in cerebral injury resulting from DHCA ( deep hypothermia circulatory arrest ) as well as the effect of SACP ( selective antegrade cerebral perfusion). Methods Twelve pigs were randomly assigned to DHCA group (n = 6) or SACP group (n = 6) at 18 ℃ for 80 min. IL-6 was assayed by ELISA. Apoptosis and NF-κB proteins were detected by fluorescence TUNEL and Western blot, respectively. The level of TLR4 was determined through qRT-PCR and Western blot. Results Serum IL-6 level of SACP group was significantly lower at the end of circulation arrest and experiment and apoptotic index and NF-κB protein were apparently lower in SACP group (P < 0.05). The level of TLR4 protein and mRNA from SACP group decreased significantly (P < 0.05). Conclusions TLR4/NF-κB pathway plays a critical role in pathogenesis of DHCA cerebral injury and attenuating TLR4/NF-κB cytokines probably contributes to neuroprotection of SACP. TLR4/NF-κB pathway may be a novel target for DHCA.
