Objective: To develop Chinese Marital Motivation and Reason Inventory (CMMRI) and examine it's reliability and validity. Methods: A 40-items, self-report measure of marital motivation and reason was developed based definition of marital motivation and reason and clinical experiences. The test-retest reliability, split-half reliability, internal consistency reliability, construct validity, and empirical validity were examined in the general sample of 1303 subjects, retest sample of 52 subjects, and validity sample of 95 subjects, aged from 6 to 91 years. Results: The stability coefficients, split-half reliability, Cronbach's ?coefficients were 0.62~0.80, 0.61~0.79 and 0.62~0.80 for 4 dimensions. There were significant differences between subjects in separation and divorcee and subjects in marriage on the CMMRI. In the confirmatory analysis of four factors model, fit statistics for the model best explained the observed relationships between the item scores and they attained the lower x2/df ratios and RMSEA, and higher IFI, TLI, CFI, PNFI and PCFI. Conclusion: The stability, internal consistency, and validity of the CMMRI are good and meet with psychometric standard.

Objective To investigate the roles of activin A(ACT-A) and follistatin(FS) in renal interstitial fibrosis.Methods Renal interstitial fibroblasts were isolated from SD rat kidney and primarily cultured.The cells were divided into A group,F group and A+F group,and then each group was further divided into 5 subgroups according to their culture media being added with ACT-A(0,0.3,3,30,or 100 ng/ml),FS(0,0.3,3,30,or 100 ng/ml),and ACT-A(30 ng/ml) plus FS(0,0.3,3,30,or 100 ng/ml) respectively.Levels of type Ⅳ collagen(Ⅳ-C) and hydroxyproline(HYP) in the supernatants of cultured fibroblasts were measured by ELISA assay.Results Concentrations of Ⅳ-C and HYP in cultured rat renal interstitial fibroblasts were in a dose-dependent manner with ACT-A treatment.FS had no effect on these concentrations,but it inhibited the effects of ACT-A on Ⅳ-C and HYP in the supernatants of cultured fibroblasts in a dose-dependent manner.Conclusion ACT-A might be involved in occurrence and development of renal fibrosis by affecting renal interstitial fibroblasts.Exogenous FS could suppress the effects of ACT-A on the cultured renal fibroblasts.

AIM:To study the effect of different surgeries for vision and postoperative complications in leprosy patients with lagophthalmos.METHODS:A retrospective analysis.Totally 68 leprosy patients (97 eyes) with lagophthalmos were selected who treated with different surgeries during May 2007 to September 2015 in our sanatorium.The surgeries included nylon thread correction surgery, tarsorrhaphy, temporalis transposition surgery.We observed and compared the best corrected visual acuity(BCVA) and the rate of postoperative complications, such as epiphora, lacrimal duct injury, hard to open eyes, infection at the inner and lateral canthus and scar formation of lacrimal apparatus.RESULTS:The effect on BCVA of patients treated with nylon thread correction surgery and tarsorrhaphy:the preoperative and postoperative BCVA was significantly different of the two groups (Z=-4.193,-4.213;P<0.05);the preoperative and postoperative BCVA was not significantly different of the patients underwent temporalis transposition surgery (Z=-1.532, P >0.05).The postoperative complications:(1) epiphora:there was 91% in patients underwent nylon thread correction surgery, 89% in patients underwent tarsorrhaphy, 59% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=12.198, P<0.05);(2) lacrimal duct injury:there was 66% in patients underwent nylon thread correction surgery, 95% in patients underwent tarsorrhaphy, 41% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=22.415, P<0.05);(3) hard to open eyes:there was 56% in patients underwent nylon thread correction surgery, 55% in patients underwent tarsorrhaphy, 22% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=8.795, P<0.05);(4) infections:there was 84% in patients underwent nylon thread correction surgery, 3% in patients underwent tarsorrhaphy, 11% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=60.858, P<0.05).CONCLUSION:There are certain clinical efficacy for lagophthalmos caused by leprosy after surgery, especially patients after temporalis transposition surgery can close eyes by oneself.And their vision does not change significantly, which suggests that this surgery may prevent exposure injury for cornea.But the iatrogenic injury, the vision decrease in patients underwent other surgeries and the ocular tissue damage, such as epiphora, lacrimal duct injury, hard to open eyes, infection at the inner and lateral canthus and scar formation of lacrimal apparatus should be pay more attention to.

Partial deletion of the long arm of chromosome 7 is a rare disease and is prone to missing the diagnosis or being misdiagnosed.Here we present a case of a 13-year-old boy that showed symptoms such as growth-retardation,moderate intellectual disability,hypotelorism,microcephaly,epicanthal folds,genu varum and lumbar vertebral cleft,but it did not show serious symptoms like cleft lip,urogenital malformation and hypotonia.He was eventually diagnosed as partial deletion of the long arm of chromosome 7 syndrome through gene analysis.Considering the rare incidence of this disease and more rarely for being hospitalized to endocrine ward due to growth retardation,this case report can provide more information for clinic diagnosis and differential diagnosis for growth retardation.

Objective To discuss the correlation between peak intensity (PI) of contrast enhanced ultrasound and injury severity after liver ischemia reperfusion.Methods Pringle's maneuver was used to establish the liver 15-min ischemia model.Contrast enhanced ultrasound was used to observe the hepatic perfusion after reperfusion of 1 h,6 h and 24 h,and the PI was recorded.The correlation analysis on PI with alanine aminotransferase (ALT),aspartate aminotransferase (AST) and pathologic changes (Suzuki standard) was done.Results PI decreased after 1 h,6 h,and 24 h of liver reperfusion,most significantly at 6 h.ALT reached the peak after 1 h of reperfusion and then decreased after 6 h and 24 h.AST increased after 6 h of reperfusion and decreased after 24 h.After 1 h of reperfusion,mild injury appeared in pathology and the injury became severe after 6 h,then it got moderate-to-severe after 24 h of reperfusion.PI was negatively correlated to ALT,AST and pathologic injury degree.Conclusion The PI relates to the degree of hepatic injury after liver ischemia/reperfusion.The more severe the injury is,the lower the PI.

A poly( GMA-EGDMA) coated SPME fiber was prepared using an in-situ polymerization by direct bonding to the surface of a polydopamine-modified stainless steel wire. Then the fiber was modified by sulfuric acid. A novel solid phase microextraction coating coupled to high performance liquid chromatography ( HPLC) method based on the as-prepared fiber was developed for the determination of four pharmaceuticals and personal care products ( PPCPs) in water samples. The influences of extraction parameters, including pH, extraction time, extraction temperature and salt addition were investigated. 3 mL water sample was extracted by the as-prepared fiber for 60 min at 30 ℃, and then desorbed with mobile phase for 30 min, respectively. Desorption solution was analyzed by HPLC-DAD ( diode array detection ) . The results indicated that the extraction yield of the fiber was good for four PPCPs. The linear correlation coefficients were>0. 997 with the linear range of 2-200 μg/L. The limits of detection (S/N=3) were 0. 5-5 μg/L with RSD (n=5) of 4. 1%-11. 9%. The recoveries of four PPCPs at spiked level of 20, 50, 100 μg/L were within the range of 70. 6%-105. 5%. The results showed that this method was easy, green, accurate and precise, and could be used to assay the four PPCPs in real water samples.
