Leptin is type I cytokine detected recently.It takes part in physiological action such as energy balance, fat storage and process of metabolism,reproduction and hemopoiesis in vivo.Leptin may be an important role between adipose tissue and genital system.Lack or excessive of leptin is related to infertility in some diseases involving in nutritional status. Leptin takes part in female infertility pathogenesis in hypothalamus pituitary gland gonad axia and other respects.

Chronic constipation (CC) is one of the most common digestive diseases with high prevalence and long course.CC patients often suffer from sleep disorders and psychological problems such as anxiety and depression.Somatic and mental symptoms may affect with each other, so a vicious circle will develop to impair patients′ quality of life (QOL) and increase their economic burden.The article reviews the impact of chronic constipation on QOL and economic burden of patients, indicating that clinician should pay sufficient attentions on chronic constipation.

Objective To summarize the nursing experience of combination therapy of highly agglutinative staphylococcin (HASL) with cisplatin for patients with malignant pleural effusions. Methods After fully draining of pleural fluid in 62 cases with malignant pleural effusion through pleural puncture through central venous catheters and simply suction bottles, we injected HASL and cisplatin into the patients' pleural cavities. During the therapeutic process, firstly, we drained the pleural fluid fully before injection, secondly, we directed the patients to cooperate well and alter the positions properly, and thirdly, we closely observed the patients' condition and adverse reactions. Results 54 of 62 cases were effective after the therapies. The effective rate was 87.1%.Conclusions In order to achieve a satisfled curative effect and reduce the adverse reactions, we need the cooperation of the patients, fully draining of the pleural fluid before injection and proper alternation of the patients' positions during the treatment process.

Irritable bowel syndrome(IBS)is one of the most common functional gastrointestinal disorders,which severely affects the life quality of patients. Currently,the pathogenesis of IBS has not yet been clarified. Visceral hypersensitivity and central algesia abnormality may be involved in the pathogenesis of IBS. Antidepressants can improve abdominal pain,abdominal discomfort,mental disorders and abnormal defecation and enhance the quality of life. This article reviewed the advances in study on antidepressants in treatment of IBS.

Objective To analyze the relationship between pre － pregnancy body mass index ( BMI) ，gestational weight gain ( GWG) and the birth weight of infants，and explore the effect of weight change before and during pregnancy on low birth weight ( LBW) and macrosomia． Methods Women were enrolled by the Chinese Pregnant Women Cohort Study during first trimester． Each respondent＇s weight before and during pregnancy and the birth weight of infant were collected after fellow up． Prepregnancy BMI was divided into underweight，normal and overweight /obesity groups and GWG was divided into suitable， insufficient and excessive groups． Multivariate Logistic regression was adopted to explore the relationship be- tween pre－pregnancy BMI，GWG and newborn＇s birth weight． Ｒesults Women＇s prepregnancy BMI and GWG were associated with neonatal birth weight ( all P＜0. 05) ． Prepregnancy overweight or obesity ( OＲ=2. 339，95% CI: 1. 674－2. 282，P＜0. 001) and excessive GWG ( OＲ= 1. 398，95% CI: 1. 188－1. 978，P= 0. 048) were shown as risk factors for macrosomia． Insufficient GWG increased LBW risk ( OＲ = 1. 479， 95% CI: 1. 461－1. 679，P= 0. 035) while excessive GWG declined LBW risk ( OＲ= 0. 428，95% CI: 0. 225 －0. 817，P= 0. 010) ． Under weight－insufficient GWG was risk factor of LBW ( OＲ= 1. 335，95% CI: 1. 048 －2. 319，P= 0. 048) while normal BMI－excessive GWG ( OＲ= 1. 088，95% CI: 1. 016－1. 675，P= 0. 038) and overweight /obesity－excessive GWG ( OＲ= 1. 498，95% CI: 1. 244－2. 017，P= 0. 046) were associated with higher risk of delivering macrosomia． Conclusions Prepregnancy BMI and GWG were associated with infant＇s birth weight and women were suggested to maintain their weight in recommended range before and during pregnancy．

A rapid and sensitive liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) method for quantification of sitagliptin in human plasma and urine had been developed. This method was applied to the pharmacokinetics study of sitagliptin tablet after single- and multiple-dosing in Chinese population. Plasma samples were prepared by a liquid-liquid extracted method, and urine samples were diluted. Compounds were analyzed by multiple reaction monitoring (MRM) mode with a electrospray ionization (ESI) interface. Mobile phase consisted of methanol and water (85 : 15, v/v). The linear concentration range of calibration curve was 0.5-1 000 ng.mL-1. and 0.2-100 µg.mL , intra-run/between-run accuracy was 98.98%-103.69% and 97.63%-102.29%, intra-run/between-run precision was <5.51% and 4.26% for plasma and urine sample, respectively. The stability of sitagliptin stock solution was tested for 55 days at -30 °C. Sitagliptin was stable when stored under the following conditions: 24 hours in the autosampler after sample preparation; 24 hours at room temperature, after 3 freeze and thaw cycles (from -30 °C to room temperature), 40 days at -30 °C for plasma and urine samples. The absolute recovery in plasma was 71.1%, and no matrix effect was founded. This method was proved simple, specific, sensitive, rapid and suitable for pharmacokinetics study of sitagliptin in human being.
