In the view of physiology,sleep can be described as an important modulatory factor for hormone release,glucose regulation,and cardiovascular function.The circadian rhythms of hormones is mainly associated with sleep,which is largely mediated by neuroendocrine system.Sleep deprivation will disrupt this rhythm,leading to a series of metabolic diseases.We published an article in 《J Clin Endocrinol Metab》 titled Association between sleep duration,daytime nap duration,and osteoporosis varies by sex,menopause,and sleep quality,which suggested that sleep durations of 7-8 h/day,9-10 h/day,and ≥ 10 h/day,as well as longer daytime napping times,tend to present higher risks of having osteoporosis,and this tendency is especially obvious in postmenopausal women reporting good quality sleep.

Menarche and menopause are two important physiological periods that denote the beginning and the end of normal reproductive life.Studies have suggested that ages at menarche and menopause are important biological markers,and are also predictors of several chronic diseases.We published one manuscript in J Clin Endocrinol Metab titled Associations between age at menarche and menopause with cardiovascular disease,diabetes,and osteoporosis in Chinese women,which suggested that ages at menarche and menopause are not associated with diabetes,delayed menarche and menopause are associated with decreased risk of cardiovascular disease risk and early menopause with high risk of osteoporosis.

Objective To approach the prognostic factors of head and neck adenoid cystic carcinoma.Methods Fifty-eight head and neck adenoid cystic carcinomas were treated from January 1999 to December 2007.The demographic and clinicopathological data were obtained from a retrospective chart review.The follow-up and survival analysis were carried out to analyze the significant prognostic factors.Results Using the univariate analysis,the variables,such as histologic type,perineural invasion,vascular invasion,recurrence,metastasis and TNM stage were found significantly associated with a worse prognosis (P ＜ 0.05 ).Multivariate analysis showed that histologic type,perineural invasion and TNM stage had an independent prognostic effect on survival (P ＜ 0.05 ).Conclusion The variables including histologic type,TNM stage,perineural and vascular invasion,recurrence and metastasis are important prognostic factors for head and neck adenoid cystic carcinoma.

To study the mechanism of human chronic renal allograft rejection, kidney tissues were taken from 16 patients with chronic renal allograft rejection and from 5 healthy subjects, and underwent the frazed section staining for ICAM-1 and VCAM-1 to anti-ICAM-1 and anti-VCAM-1 respectively by using immunohistochemistry(ABC).The results showed that there were differ-ent distribution of ICAM-1 and VCAM-1 expression in nomal kidney and renal allograft during chronic rejection.It was suggested that ICAM-1 and VCAM-1 might play an important role in the pathogenesis of human chronic renal allograft rejection.

Objective To explore the clinical significance of blood serum AFP determination in gravis type viral hepatitis. Methods The level of blood serum AFP was determined by radioimmunoassay in 85 eases of gravis type viral hepatitis, and its change was observed in a dynamic state. Results The abnormality rate of AFP was 83. 6% in the patients of gravis type viral hepatitis. The abnormality rate of AFP in acute gravis type viral hepatitis was significantly lower than that in suhacute severe hepatitis and chronic severe hepatitis(P < 0.01). The survival rate in the team with high level of AFP was significantly higher than that of teams with normal or low level of AFP(P <0.01～0.05) in the patients of gravis type viral hepatitis. The blood serum AFP level in the survivors was significant-ly higher than that of the death in the patients of gravis type viral hepatitis(P <0.01). Conclusions The blood ser-um AFP determination in gravis type viral hepatitis,can be used as a sensitive index for prognosis. A high level of AFP indicates that the hepatic cells regeneration is active and the prognosis is relatively better.

Objective To investigate the effect of LF on blood biochemistry,cytokines in rats with NASH in order to approach possible mechanism of LF against NASH.Methods 50 male SD rats were randomly divided into the normal control group(10 rats),the model group(10 rats),the Essentinale group(10 rats)、the LF high dose group(10 rats)and the LF low dose group(10 rats).Except for the normal control group which was raised by standard animal feeds,others were all raised by high fat feeds to make NASH model and administered by Essentinale,high dose LF and low dose LF for 12 weeks.Hepatic lipid contents,plasma TG,CHO,HDL-C,LDL-C,ALT,AST and TNF-?,FFA,Leptin concentrations were evaluated,as were histopathological changes in the liver.Results In this NASH model,the liver FZ(liver weight /body weight),plasma CHO,LDL-C,ALT,AST and TNF-?,FFA,Leptin concentrations were higher than that in normal control group,but the levels of serum HDL-C and TG were reduced.In addition,the histopathological showed increased fatty droplets within hepatocytes and liver inflammation.The levels of serum ALT,AST,HDL-C,TNF-?,Leptin,FFA and hepatic CHO,TG contents in the LF high dose group and LF low dose group were reduced compared with that in the model group,while the levels of serum TG,HDL-C were enhanced remarkably.In addition,liver inflammation was improved evidently.Conclusions Treatment with LF might improve non-alcholic steatohepatitis,because LF inhibits the elevation in the level of plasma cytokine.

Objective To study the preventive and therapeutic effect of doxazosin mesylate (Cardura) in the management of vesical spasm. Methods Two hundred and fifty six cases were randomized into two groups: the study group was given Cardura 4 mg at bedtime, while the control group was given probanthine 15 mg twice a day. All the patients were given 8 ng of Vitamin Ks three times a day. Results There was significant difference in the incidence of vesical spasm between study group and control group (P＜0.01). Conclusions Cardura can decrease the urethral closure pressure, and reduce excitability of bladder detrusor muscle. So it is effective for the relief of vesical spasm.

Objective To investigate gender differences in mortality after percutaneous coronary intervention(PCI) in contemporary "real world" practice and determine whether female gender is an independent risk factor for PCI mortality.Methods A total of 2 493 patients including 1 860 men(male group) and 633 women(female group) who underwent PCI during July 1st,2004 to September 30st,2005 in Beijing Anzhen Hospital were retrospectively investigated and followed up.The risk factors before PCI and the mortality rates post PCI were compared.Results Women undergoing PCI were older and had more comorbidities than men.However,men were more likely to have depressed ejection fraction,prior myocardial infarction,and prior coronary revascularization.Women demonstrated a ten-fold higher in-hospital mortality rates compared with men(1.1% vs 0.1%,P

Objective To investigate the value of Helicobacter pylori (HP),blood carcinoembryonic antigen (CEA),carbohydrate antigens 72-4 (CA72-4) and CA24-2 in the screening of gastric cancer.Methods The contents of HP,blood CEA,CA72-4 and CA24-2 in 50 healthy controls,45 patients with benign gastric lesions mnd 70 patients with gastric cancer were detected.According to the number of positive cases,the positive rate of single detection and the positive rate of combined detection were calculated.Sensitivity,specificity,and accuracy of serum tumor markers were calculated according to HP single and combined detection.Results The positive rate of each individual detection and 4 joint detection in gastric cancer group was significantly different from that in the benign lesion group and the normal control group (P ＜0.01).The positive rate of 4 joint detection in gastric cancer group was 89.25％,and the difference was statistically significant (P ＜0.01).There was no significant difference in the positive rate of the single test and the 4 joint detection in benign stomach group and normal control group (P ＞ 0.05).The sensitivity,specificity and accuracy of HP,blood CEA,CA72-4,CA24-2 joint detection were significantly higher than single detection (P ＜ 0.05).Conclusions Joint detection was significandy better than single detection,and can significantly improve the detection rate of gastric cancer.

Objective To investigate the clinical and pathological features of colonic polyp canceration and related risk factors of colon polyps,and explore clinicopathologic features and major risk factors of the canceration of polyps of colon polyps.Methods Totally 80 patients with colon polyps including 6 cases of cancerations and 20 patients with colon cancers were selected from Xuzhou Tumor Hospital Admissions.Those patients were divided into 74 cases of non cancer group and 26 cases of cancer group.The clinical data,the detection index and the statistical analysis were performed.Results The clinical features of patients included 51 cases of multiple polyps,30 cases of fatty liver,13 cases of fecal occult blood positive,and 30 patients with colonoscopy.There were 218 polyps,191 data intact,and 6 cases showed cancer (3.14％).Inflammatory polyps mainly occurred in rectum,cecum,and significant risk other than the colon.Tubular adenoma occurred mainly in the transverse colon.Sigmoid colon cancer colon polyps of the highest risk showed OR =2.30 (P ＜ 0.05).The cancer risk from high to low was from tubular villous adenoma to villous adenoma hair (P ＜0.01),and no difference in tubular adenoma cancer risk (P ＞0.05).There was no difference between the indexes of the canceration group and the non cancerous group (P ＞ 0.05).The single factor analysis showed pathological type,and the lesion were the main risk factors of malignant colonic polyps (P ＜ 0.05).Multi-factor regression analysis showed WBC,pathological type,and the lesion were the main risk factors of malignant colonic polyps (P ＜ 0.05).Conclusions The colonic polyps in male have higher incidence with fatty liver,hypertension and other pathological features,and are mainly tubular adenomas,inflammatory and hyperplastic polyps,with different lesions,pathological types occur and different cancer risk.
