Objective: To evaluate the effects of dietary behaviors on the risk of hypertension, diabetes and cardiovascular diseases. Methods: A total of 12 208 subjects aged 18-60 years old were investigated by questionnaires to collect demographic data, dietary behaviors and lifestyle information, when they did health examination in a tertiary hospital in Beijing from 2014 to 2019. During the observation period of five year, the incidence of hypertension, diabetes and cardiovascular diseases were collected through health examination files every year. The multivariate logistic regression model was employed to analyze the associations of dietary behaviors with hypertension, diabetes and cardiovascular diseases. Results: The study included 6 218 ( 50.93% ) males and 5 990 ( 49.07% ) females. The cumulative incidence rates of hypertension, diabetes and cardiovascular diseases were 7.75%, 2.72% and 3.49%, respectively. The multivariate logistic regression analysis indicated that the high-sodium diet ( OR=1.422, 95%CI: 1.191-1.697 ) , eating fast ( OR=1.457, 95%CI: 1.102-1.974 ), eating more refined grain ( OR=1.251, 95%CI: 1.050-1.490 ) and drinking milk less than once a week ( OR=1.316, 95%CI: 1.022-1.697 ) were risk factors for hypertension. The high-sodium diet ( OR=1.344, 95%CI: 1.048-1.725 ), eating fast ( OR=1.733, 95%CI: 1.046-2.871 ), eating more meat ( OR=1.651,95%CI: 1.263-2.158 ) were risk factors for diabetes. High-sodium diet ( OR=1.501, 95%CI: 1.192-1.889 ) was risk factors for cardiovascular disease. Conclusion The diet with high sodium, more meat and refined grain as well as eating fast can increase the risk of hypertension, diabetes and cardiovascular diseases.

Objective To evaluate the clinical value of 6 h 99mTc-diethyl iminodiacetic acid (99mTc-EHIDA) planar hepatobiliary scintigraphy (HBS),6 h tomographic HBS and 24 h planar HBS in diagnosis on biliary atresia(BA).Methods Seventy cases(32 male,38 female) with continuous jaundice received planar and tomographic HBS in Beijing Friendship Hospital from Jan.2005 to Dec.2007.The mean age was 48.7 d (29 d-4 months).According to final diagnosis,all cases were divided into BA group (45 cases) and non-BA group (25 cases).All cases fasted at least 4 hours before HBS.The equipment was 3 head IRIX from Philips company with low energy high resolution collimator.The tracer was 99mTc-EHIDA and the radiochemistry purity was more than 95 percent.The dosage was 7.4 MBq/kg.All diagnosis demonstrated by operation pathology and clinical follow-up.All cases received HBS at 5,10,15,20,30 min and 1,6 h after tracer injection.HBS would ended if radioactivity appeared in gallbladder or intestine.These cases would received tomographic HBS and 24 h HBS if radioactivity did not appear in gallbladder or intestine at 6 h post injection.All these images were analyzed by 2 or more nuclear medicine physicians.Results There were not radioactivity appearing in gallbladder and intestine on planar and tomographic HBS of 27 cases,which suggested the BA.There were radioactivity appearing in gallbladder and intestine on planar and tomographic HBS of 30 cases,which suggested the non-BA.Positive rate of 6 h tomographic HBS was significantly higher than that of 6 h planar HBS and there was significantly difference between the 2 methods.Positive rate of 6 h tomographic HBS was significantly higher than that of 24 h planar HBS and there was significant difference between the 2 methods.Conclusions 99mTc-EHIDA HBS is a noninvasive,safety,valuable examing method and has definitely clinical value in the diagnosis on BA.The clinical value of 6 h tomographic HBS is significantly higher than that of 6 h planar HBS and 24 h planar HBS.

Objective To study the mode and clinical implications of onset of spontaneous tosade de pointes in the congenital long QT syndrome. Methods We reviewed electrocardiograms (ECGs) of 55 patients with congenital QT syndrome for syncope. Documentation of the onset of tosade de pointes was available for 16 patients. All these patients had "definitive long QT syndrome" by accepted clinical and ECG criteria. Results One hundren and forty-nine runs of tosade de pointes were documented in 16 patients,of whom,there were 130 runs of pause-dependent tosade de pointes. Conclusion Our results show that the pause-dependent tosade de pointes,which has been recognized as a hallmark of tosade de pointes in the acquired long QT syndrome,plays a major role in the genesis of tosade de pointes in the congenital long QT syndrome.

Objective: To study the pharmacological action of Mahuang Compound Capsule(MCC) (Herba Ephedrae, Semen Armeniacae Amarum, Fructus Schisandrae, etc.). Methods: The study was carried out through the observation of ammonia induced cough model in mice and acrolein induced cough model in guinea pigs treated with MCC, its effects on asthma model of guinea pigs induced by histamine and acetylcholine mixture and on isolated tracheas smooth muscle of guinea pigs were also studied. Results: MCC administrated orally showed significant antitussive effect in ammonia induced cough model in mice and acrolein induced cough model in guinea pigs. MCC could effectively prevent guinea pigs from asthma induced by histamine and acetylcholine mixture. The water extracts could antagonize histamin phosphate that contract the isolated tracheas of guinea pigs. Conclusions: MCC has antitussive and anti asthma effects.

The cupping spot is considered as one kind of skin change due to cupping treatment. With literature regarding cupping spot, the influencing factors and value of cupping spot in clinical diagnosis and treatment were analyzed, which could make a further exploration on the action mechanism of cupping treatment. The literature showed that the formation of cupping spot was related with cupping temperature, pressure, cup-retaining time, cupping area, individual difference and health condition, etc; cupping spot had the ability to assist diagnosis, prevent disease, cure disease and evaluate clinical efficacy. Previous studies on cupping spot have already made some progress, and played a positive significance on finding cupping rule and studying its mechanism. However, the research for this area is still in the primary stage, which needed deeper study to reveal scientific connotations of cupping spot.

OBJECTIVE: To evaluate the effect of intrathecal pumping tramadol on cell-mediated immunity in rats with formalin inflammatory pain. METHODS: Thirty-two Sprague-Dawley adult male rats weighting 250 approximately 300 g were randomly divided into 4 groups (n=8 in each group):Saline group (NS) and 3 tramadol groups (T1,T2,and T3). The rats were anesthetized with intraperitoneal chloral hydrate (300 approximately 350)mg/kg. Microspinal catheter was inserted into the subarachnoid space at the lumber region according to modified Yaksh techniques. In the tramadol groups,after 5 days tramadol was continuously infused through the spinal catheter at 50 (T1),25 (T2), and 12.5 microg/h (T3) for 7 days. In the NS group normal saline was continuously infused instead of tramadol. On Day 7 formalin (5%, 50 microL) was injected into the plantar surface of the left hindpaw. The number of flinches, lickings and total time of licking was recorded for 60 min.Pain intensity scoring(PIS)(0 approximately 3;0= no pain, 3=severe pain) was used to assess the antinociceptive effect of intrathecal tramadol. The rats were killed after the evaluation of pain intensity. Body weight and spleen weight were measured and spleen index (spleen weight/body weight) was calculated. T-lymphocyte function was evaluated based on Concanavalin-A(ConA) induced splenocyte proliferation. A modified lactic acid dehydrogenase(LDH) release assay was done to assess the NK cell activity. Phenotypic expressions of cell surface markers of T lymphocyte subsets (CD3+, CD3+ CD4+, CD3+ CD8+, and CD4+/ CD8+) and NK cell(CD161+) in the spleen were analyzed by flow cytometry. RESULTS: The PIS scores were significantly lower in the T1,T2,and T3 groups than those in the NS group. The spleen index and splenocyte proliferation induced by ConA were significantly suppressed in the T1 group,and the phenotypes of T lymphocyte subsets were significantly changed,but no significant difference was found in the T2 and T3 groups compared with the NS group. There were no differences in NK cell activity in the 3 tramadol groups from the control group. CONCLUSION Intrathecal pumping tramadol has significantly antinociceptive effect. Intrathecal pumping higher dosage tramadol (50microg/h) suppresses T lymphocyte proliferation and alteres T lymphocyte subset phenotype but does not affect NK cell activity. General analgesic dosage tramadol (25 and 12.5 microg/h) has no effect on the immune function.
