OBJECTIVE: To learn the prevalence of abnormal components of metabolic syndrome in postmenopausal women, and to explore the optimal body composition indices to predict the abnormal components of metabolic syndrome in postmenopausal women. METHODS: A total of 181 participants were recruited from postmenopausal women who came to Beijing Obstetrics and Gynecology Hospital for health examination between July 2006 and August 2007. They were 41-60 years of age, and there were 1-9 years since menopause. Their clinical and biochemical parameters were measured, including body height, body weight, waist circumference, hip circumference, sagittal abdominal diameter, blood pressure, follicle stimulating hormone, luteinizing hormone, estradiol, triglyceride, high density lipoprotein-cholesterol, fasting,plasma glucose, fasting insulin and body fat. The prevalence of the abnormal components of metabolic syndrome in postmenopausal women was investigated. The correlations between body composition indices and the components of metabolic syndrome were analyzed by partial correlation analysis independent of age, years since postmenopause and the level of estradiol. The body composition indices to predict the abnormal components of metabolic syndrome in postmenopausal women were explored. RESULTS: ①The prevalence of central obesity (waist circumference ≥ 80 cm), hypertriglyceridemia (triglyceride ≥1.7 mmol/L), low high density lipoprotein-cholesterol (high density lipopretein-cholesterol < 1.29 mmol/L), hypertension (systolic pressure ≥ 130 mm Hg or diastolic pressure ≥ 85 mm Hg, 1 mm Hg=0.133 kPa) and high fasting glucose (fasting plasma glucose ≥ 5.6 mmol/L)was 48.1%, 31.5%, 16.6%, 38.7% and 50.3%, respectively. ②Through partial correlation analysis, body composition indices (body mass index, waist circumference, waist-hip ratio, sagittal abdominal diameter, and body fat) had a positive correlation with triglyceride, systolic pressure, diastolic pressure and fasting plasma glucose, while a negative correlation with high density lipoprotein-cholesterol, independent of age, years since postmenopause and the level of estradiol.③Body composition indices and critical value of them used to predict the abnormal components of metabolic syndrome in postmenopausal women were as follows: hypertriglyceridemia: body mass index ≥ 24.845 kg/m~2; low high density lipoprotein-cholesterol: sagittal abdominal diameter ≥ 18.85 cm; hypertension: body mass index ≥ 23.33 kg/m~2; high fasting glucose: sagittal abdominal diameter ≥ 18.10 cm or body fat ≥ 36.515%. CONCLUSION: Central obesity and high fasting glucose are the most common metabolic disorders in postmenopausal women. Obesity is an independent risk factor of metabolic syndrome for postmenopausal women. Body composition indices and their critical values to predict the abnormal components of metabolic syndrome in postmenopausal women are found.

Purpose:To explore the expression of fatty acid synthase in non-small cell lung cancer and to detect its association with clinicopathological features and prognosis.Methods:107 patients with NSCLC who underwent surgery were followed up for more than 5 years.Fatty acid synthase were evaluated by immunohistochemisctry on formalin fixed paraffin embedded tissues and compared with benign lesion and normal tissue.Multiple clinical parameters and survival were analyzed.Results:In 107 patients with NSCLC,FAS expression was observed in 43 cases(40.2%).In contrast to benign lesions and normal tissue,FAS is significantly overexpressed in NSCLC.Survival analysis revealed that the 5-year survival rate was lower in FAS positive patients than in negative patients(16% vs 43%,p

AIM To investigate the roles of Cl- channels in Ca2+ influx induced by activaion of al- adrenoceptor subtypes in transfected-CHO cells. METHODS The effects of drugs on ?1A、?1B and ?1D- AR-induced Ca2+ influx were investigated with Fura2 fluorescence technique. RESULTS The ?1A-AR- induced Ca2+ influx was inhibited by furosemide(2 .5 ~ 10 M?mol?L- 1 )and SK&F96365(5- 15 ?mol?L- 1 ) in a concentration- dependent manner respectively; The ?1B-AR-induced Ca2+ influx could also be inhibit inhibited by NFA(2. 5 ~ 10 ?mol? L-1 ), whereas the alD AR-induced Ca2+ influx was only suppressed by NFA. In ?1B-CHO cells, Adr-triggered Ca2+ influx could be further inhibited by NFA or furosemide after the maximal inhibition by SK&F96365;SK&F96365 could further inhibit Ca2+ influx which had been inhibited by NFA or furosemide. In ?1A-CHO cells, Adr-triggered Ca2+ influx could be further inhibited by SK&F96365 after had been inhibited by furosemide; furosemide could not further inhibite Ca2+ influx which had been inhibited by S&F96365. CONCLUSION There are different characteristics of CI- channels related to ?1A、 ?1B and ?1D-AR-induced Ca2+ influx.

Two lipase active fractions Lip1 and Lip2 were purified from the cell extract of Rhizopus chinensis CCTCCM201021.Both gave a single band on SDS-PAGE after using ammonium sulfate precipitation、Phenyl-Sepharose FF、DEAE-Sepharose FF and Sephadex G100 gel filtration chromatographies.The molecular masses of two lipases were 59.2kD and 39.4kD respectively.Lip1 and Lip2 showed optimal pH at 8.0 and 8.5 and their optimal temperatures were 40℃ and 35℃ respectively.The substrate specificity of the two lipases was obviously different.Lip1 was more specific to long chain fatty acid of p-nitrophenyl esters while Lip2 had a preference for the hydrolysis of short chain fatty acid of p-nitrophenyl esters.Lip1 had 1,3-position specificity for triacylglycerols hydrolysis while Lip2 had nonspecific position.Both lipases were stimulated by Ca 2+、Mg 2+ while SDS had strong inhibition on their activities.Lip1 and Lip2 had good stability in cyclohexane、hexane、heptane and isooctane(30% V/V).

AIM: To investigate the relationship between chloride channels and the Ca 2+influx induced by adrendine(Adr). METHODS: The effects of drugs on Adr-induced Ca 2+influx were investigated with Fura-2 fluorescence technique. RESULTS: Adr-induced Ca 2+influx was inhibited by nifedipine,SK&F96365,NFA and furosemide in a concentration manner respectively; Ca 2+influx could be further inhibited by NFA or furosemide after the maximal inhibition by SK&F96365;SK&F96365 also could further inhibit the Ca 2+influx which had been inhibited by NFA or furosemide. Genistein and vanadate could reduce or increase the Ca 2+influx respectively. CONCLUSION: Ca 2+influx induced by Adr is related to VDC and ROC, and chloride channels involves in the processes.The levels of tyrosine phosphoralation affect the Ca 2+influx.

OBJECTIVETo compare the efficacy and complication of tissue selecting therapy stapler (TST) and procedure for prolapse and hemorrhoids (PPH) in the treatment of severe hemorrhoids.

METHODSClinical data of 542 cases of severe hemorrhoids undergoing TST (258 cases) or PPH (284 cases) in The First Affiliated Hospital of Fujian Medical University from November 2010 to January 2012 were analyzed retrospectively. Operative parameters, efficacy and complication 3 months after operation were assessed and compared.

RESULTSNo significant difference in cure rate between TST and PPH (96.5% vs. 95.4%) was found, while the operation time and hospital stay after operation in TST group were significantly shorter urgency [(20.6±4.7) vs. (26.4±6.3) min, (2.9±0.5) vs. (3.5±0.7) d, both P<0.05]. Incidences of postoperative pain, bleeding, anal urgency and urinary retention in TST group were significantly lower than those in PPH group (all P<0.01). No anal stenosis was observed in TST group, and 5 cases developed anal stenosis in PPH group (P<0.05). Hemorrhoid recurrence did not differ significantly between the two groups.

CONCLUSIONSThe efficacy of TST and PPH is comparable for severe hemorrhoids patients, while TST is associated with faster postoperative recovery and less complications.

OBJECTIVETo explore the effect and mechanism of electroacupuncture (EA) for Z syndrome without organic lesion (metabolic syndrome combined with obstructive sleep apnea hypopnea syndrome).

METHODSFifty-eight patients with Z syndrome were divided into three groups according to mild,moderate and severe degree. Acupuncture and EA were used at Daimai (GB 26), Zhongwan (CV 12), Xiawan (CV 10), Zusanli ST 36), Qihai (CV 6) and Huaroumen (ST 24), etc., once a day and five times a week. The treatment of ten times was a course, and two courses were acquired continuously. Sleep respiration monitoring (PSG) was done before EA and in one week after treatment respectively. Triacylglycerol (TG) fasting blood glucose (FBG) fasting insulin (INS) and serum leptin (Lep) were tested before and after treatment in the three groups.

RESULTSAfter treatment apnea hypopnea index (AHI) and the percentage of the time of arterial oxygen saturation (SaO₂) less than 90% taken in the total sleep time (SLT 90%) were improved apparently than those before treatment in the three groups (all P < 0.05). The levels of TG, FPG, INS and Lep were decreased after treatment in all groups (all P < 0.05).

CONCLUSIONEA can improve AHI and nocturnal hypoxia of Z syndrome, and the mechanism may be related to decreasing the indices of metabolism syndrome and leptin.

OBJECTIVEThis study aimed to induce carcinogenesis of lingual mucosa in C57BL/6 mice by feeding them 4-nitroquinoline 1-oxide (4NQO) solution.

METHODSA total of 85 C57BL/6 mice were randomly divided into distilled water control group (DD group, n=5), 1,2-propylene glycol control group (PG group, n=5), and experimental group (EP group, n= 75). The mice in the experimental group were medially fed in 15 cages. By contrast, the mice in DD, EP, and PG groups were watered with distilled water, 50 mg.L-1 4NQO solution, and 1,2-propylene glycol solution. The mice in EP group were executed every two weeks from week 0, and the mice in the control groups were sacrificed at the 28th week. The mice were weighed. Mucosal lesions were measured by macroscopic observation and histopathologic detection.

RESULTSOne mouse in EP group died of unknown reason. The weight of the mice in EP group presented weight loss compared with the mice in DD and PG groups after the 24th week. Seventy-nine macroscopic lesions were observed in the lingual mucosa, oral floor, and upper palatal and buccal mucosa. A total of 70 macroscopic lesions (88.6%) were located in the lingual mucosa. Mucosal lesions changed from simple hyperplasia to squamous cell carcinomas. Well-differentiated squamous cell carcinomas were observed in all mice of EP group by pathological section at the 28th week. No lesion was found in the mice of DD and PG groups.

CONCLUSIONThe animal model of lingual squamous cell carcinomas was successfully established. The periods from 12th to 16th week and 20th to 28th week were the ideal times for the research on pathogenesis of early and medial-advanced stage during carcinogenesis of squamous cell carcinomas.
