Obesity is a severely public health problem the whole society faces, and it is correlated closely with many diseases, such as diabetesⅡ, hypertension, coronary heart disease,gallstone, and so on. Therefore it threatens people's survival quality severely. Obesity is a multiple-factor disease including genetic, metabolic and behavioral factor, and the gene is the main determining factor. With the development of molecular biology technique, people have founded several genes involved in obesity. Among these genes, the research on obese gene is the most profound. The protein leptin is the expression product of the obese gene. This review elucidates the structure, the main biological function, the mechanism of leptin and it's relationship with obesity.

OBJECTIVE:To investigate the effects of anisodamine combined with oxytocin on labor process of lying-in women with prolonged active phase in the first labor process and related indicators of newborns. METHODS:216 lying-in women with pro-longed active phase in the first labor process were randomly divided into control group(108 cases)and observation group(108 cas-es). All lying-in women were artificially ruptured,based on it,control group was given 2.5 u Oxytocin for injection,adding into 500 ml 5% Glucose injection by intravenous infusion,the drip rate was appropriately adjusted based on contractions;observation group was additionally given 10 mg raceanisodamine hydrochloride,adding into 10 ml 5% Glucose injection by intravenous infu-sion by 5 min slow intravenous injection. The fetal heart was warded to closely observe the labor process during medication. The cervical maturity,labor process time,delivery mode and postpartum situation of lying-in women,Apgar score,body mass and inci-dence of adverse reactions of newborn in 2 groups were observed. RESULTS:The lying-in women cases with no less than 9 cervi-cal maturity,natural delivery rate and 5 min newborn Apgar score in observation group were significantly higher than control group, lying-in women cases with 7-9 scores and less than 7 scores,cesarean section rate,perineal/ straight cut rate and 24 h postpartum hemorrhage were significantly lower than control group,the second,the third and total labor process were significantly shorter than control group,the differences were statistically significant(P<0.05);there were no significant differences in the time of incubation period and active period,forceps delivery rate,body mass of newborn and incidence of adverse reactions in 2 groups (P>0.05). CONCLUSIONS:Anisodamine combined with oxytocin can accelerate the cervical dilation of lying-in women with pro-longed active phase,shorten labor process,reduce cesarean section rate and improve prognosis,it did not affect the body mass of newborns,with good safety.

Objective To explore the effect of curcumin on the activity and migration of as well as c-kit mRNA expression in melanocytes.Methods Human epidermal melanocytes were isolated from the prepuce in adolescents and subjected to primary culture.To estimate the effect of curcumin on the proliferative activity of melanocytes, some melanocytes were randomly divided into several groups to be cultured in the MelM-2 medium with or without the presence of 5, 10, 20 or 30 μmol/L curcumin, the MelM-2 medium containing curcumin of 5-30 μmol/L served as the drug control groups, and the MelM-2 medium without curcumin served as the blank control group.After 24 and 48 hours of culture, MTS assay was performed to evaluate the proliferative activity of melanocytes.Some cultured melanocytes were randomly divided into 4 groups to be cultured in the MelM-2 medium with 0, 5, 10 and 20 μmol/L curcumin respectively for 48hours.Then, wound scratch assay was conducted to estimate the migratory activity of melanocytes, and real-time fluorescence-based quantitative PCR to quantify the mRNA expression of c-kit in melanocytes.Statistical analysis was carried out by factorial design analysis of variance (ANOVA), one-way ANOVA and least significant difference (LSD)-t test.Results The proliferative activity of melanocytes was significantly decreased at 24 and 48 hours in the 30-μmol/L curcumin group compared with the negative control group (0.783 ± 0.053 vs.1.000 ± 0.018 at 24 hours, 0.637 ± 0.015 vs.0.993 ± 0.064 at 48 hours, both P ＜ 0.05), while no significant differences were observed between the other curcumin groups and the negative control group (all P ＞ 0.05).The 48-hour treatment with curcumin could significantly inhibit the migration of melanocytes in the 5-, 10-and 20-μmol/L curcumin groups compared with the control group (all P ＜ 0.05).The mRNA expression level of c-kit was also significantly reduced at 48 hours in the 5-, 10-and 20-μmol/L curcumin groups compared with the control group (1.799 ± 0.372, 1.539 ± 0.224 and 1.026 ± 0.038 vs.3.371 ± 0.352, all P ＜0.05).Conclusion Curcumin at low concentrations (≤ 20 μmol/L) has no obvious cytotoxicity against melanocytes, but can inhibit the migration of and c-kit mRNA expression in melanocytes, while curcumin at 30 μmol/L can promote the apoptosis of melanocytes.

Background:Ulcerative colitis(UC)is often accompanied by a variety of extraintestinal manifestations. Recently, the role of extraintestinal manifestations in diagnosis and treatment of UC has aroused widespread concern in clinical practice. Aims:To study the extraintestinal manifestations of patients with UC in order to elevate diagnosis level of UC. Methods:A total of 208 inpatients from June 2008 to September 2011 at Beijing Military General Hospital were enrolled. The extraintestinal manifestations of UC were retrospectively analyzed. Results:The ratio of male to female was 1. 14: 1, mean age was(41. 17 ± 13. 57)years,mean disease duration was(62. 6 ± 79. 4)months. Thirty-three patients had proctitis,52 had left-sided colitis,and 123 had extensive colitis. Forty-nine patients were mild UC,80 were moderate UC, and 79 were severe UC. The incidence of extraintestinal manifestations was 28. 8%(60 / 208);13 patients(6. 3% )had more than one extraintestinal manifestation. The main extraintestinal manifestations were oral ulcer(13. 0% ),arthropathy (11. 1% ),hepatobiliary disease( 3. 8% ) and skin lesion( 1. 4% ). The trend of incidence of extraintestinal manifestations increased from patients with proctitis,left-sided colitis to extensive colitis(21. 2% ,28. 8% ,30. 9% , respectively),however,the difference was not statistically significant(P > 0. 05). No significant difference in incidence of extraintestinal manifestations in patients with mild UC,moderate UC and severe UC was found(22. 4% ,33. 8% ,27. 8% , respectively)(P > 0. 05). Conclusions:Patients with UC are often accompanied by extraintestinal manifestations,and the recognition of extraintestinal manifestations is helpful for improving diagnosis and treatment level of UC.

OBJECTIVE:To compare the efficacy and safety of Leonurus artemisia cream and Dan’e fukang cream in the treat-ment of primary dysmenorrhea. METHODS:80 patients with primary dysmenorrheal were randomly divided into L. artemisia cream group (40 cases) and Dan’e fukang cream group (40 cases). L. artemisia cream group received L. artemisia cream 10 g, orally,twice a day. Dan’e fukang cream group received Dan’e fukang cream 10 g,orally,twice a day. The treatment was stated before 10 days of menstruation. 10 days was regarded as 1 treatment course,and it lasted for 6 courses. Cold drink and food were forbid during medication,washing face and feet with warm water,soaking feet with hot water if they can,paying attention to keep the lower abdomen and legs warm. If patients felt unbearable pain in menstruation,0.3 g Ibuprofen sustained release capsule was given,orally twice a day. Clinical efficacy,symptom score(dysmenorrhea degree,abdominal pain,lumbosacral pain)before and af-ter treatment,dysmenorrhea duration,frequency of taking painkillers and the incidence of adverse reactions in 2 groups were ob-served. RESULTS:There were no significant differences in the total effective rate and the incidence of adverse reactions in 2 groups (P>0.05). Before treatment,there were no significant differences in dysmenorrhea degree,abdominal pain,lumbosacral pain score,dysmenorrheal duration and frequency of taking painkillers in 2 groups (P>0.05). After treatment,the dysmenorrhea degree,abdominal pain,lumbosacral pain score in 2 groups were significantly lower than before,and Dan’e fukang cream group was lower than L. artemisia cream group with statistical sighificance(P<0.05),and dysmenorrheal duration and frequency of taking painkillers were significantly lower than before,with statistical significance(P<0.05),while there was no significant difference in 2 groups(P>0.05). CONCLUSIONS:Both L. artemisia cream and Dan’e fukang cream have good efficacy and safety in the treat-ment of primary dysmenorrhea,while Dan’e fukang cream is superior to L. artemisia cream in terms of improving clinical symp-toms.

Objective: To quantitatively study the incidental extra-cardiac ifndings (ECFs) by coronary computed tomography angiography (CCTA) in patients with suspected coronary artery disease (CAD) in order to better recognize those lesions in clinical practice.
Methods: A total of 1169 suspected CAD patients received CCTA in our hospital from 2011-06 to 2013-03 and 1030 patients were enrolled in this study. There were 589 in-patients, 441 out-patients and 549 patients≥60 years of age,481 patients < 60 years of age. 3 physicians evaluated the incidental ECFs in the full ifeld of view (FOV) in different window level and window width for lung, mediastinum, thorax and upper abdominal areas. Clinical relevance of ECFs were classiifed by corresponding scores. Score 1, the patients with severe lesion need immediate treatment, score 2, the lesion with clinical and prognostic signiifcance and score 3, the ifnding without clinical signiifcance.
Results: There were 197/1030 (19.1%) patients having 224 ECFs and 27 (2.6%) patients having 2 ECFs; 90/1030 (8.7%) patients having 106 signiifcant lesions including 3 (0.3%) of lung cancer and 8 (0.8%) of pulmonary embolism; 107 patients with 118 lesions without signiifcance. ECFs were found in 114/589 (19.4%) in-patients and in 83/441 (18.8%) out-patients, P>0.05; 76/481 (15.8%) of patients < 60 years of age and 121/549 (22.0%) of patients≥60 years,P<0.05.
Conclusion: Unexpected ECFs detection rate was 19.1% in patients undergoing CCTA without further radiation exposure by reconstruction with the full FOV setting, and 8.7% of ECFs had clinical signiifcance. Radiologists should routinely analyze the extra-cardiac organs in CCTA.

A total of 107 vitiligo patients were randomly divided into 3 groups.Group A received an intralesional injection of Bacillus Calmette-Guérin-polysaccharide nucleic acid (BCG-PSN) (n =34),group B Compound Glycyrrhizin Tablets (n =36) and group C both (n =37).Before treatment and 3 months after treatment,cellular immune function was detected for each group.Paired comparisons of 3 groups before and after treatment showed that CD4 +,CD4 +/CD8 + ratio increased (all P ＜ 0.05) and CD8 + decreased (P ＜0.05).After treatment,as compared with groups A and B,CD4 + increases (both P ＜ 0.05) and CD8 + decreased in group C (P ＜0.05).Group C had an efficiency rate of 91.9％ and it was higher than the other two groups (both P ＜ 0.05).An intralesional injection of BCG-PSN plus Compound Glycyrrhizin Tablets could improve immune function and treat vitiligo patients efficiently.
