Objective To study the prevalence and the distribution of several chronic diseases which affect the life quality and the health of the Shanghai elderly people. Methods Stratified cluster sampling method was used in the survey of the prevalence rate of several common chronic diseases (self reported) in 12 590 residents ≥60 years of age in 22 urban and 14 rural communities in Shanghai. Results The total prevalence rate of several chronic diseases in the elderly is 60 3%, with male being 59 4% and female being 61 9%. The total prevalence rate in the urban elderly was 66 5%, significantly higher than that of the rural elderly(53 9%). In urban areas, female's prevalence was higher than the males. While in rural area no difference between male and female was observed. In urban areas, the prevalence from high to low stood hypertension(33 6%), cataract(18 3%), chronic obstructive pulmonary disease (COPD)(11 9%), coronary heart disease(9 1%), other heart diseases(7 9%), diabetes mellitus(5 9%). In rural areas, the prevalence from high to low stood hypertension (20 9%), COPD(15 2%), cataract(7 0%), deafness(5 7%), other heart diseases(4 3%), osteoideformed or osteoporosis(4 2%). Conclusions The distribution and the status of the chronic diseases in rural areas are significantly different from that of urban areas. We should carry out different strategies according to different conditions for enhancing the health and life quality of the elderly.

95%; D, coronary acute total occluded, according to the results of selective coronary angiography. Myocardial reperfusion levels were evaluated using the different methods mentioned above at 15 min after PCI. The quantitative parameters of MCE involved contrast peak intensity (A), time to peak intensity (TP) and area under the curve (AUC), representing myocardial blood volume, reperfusion velocity and myocardial blood flow respectively. Results The CTFC was not different between the coronary artery stenosis groups and the normal group. Coronary artery blood flow was slower in group D than that in group A while myocardial blood volume and myocardial blood flow of MCE quantitative parameters markedly decreased in group C than those in group A, and three MCE parameters in D group were significant difference compared with group A. Conclusion Quantitative intracoronary MCE was more accurate in the evaluation of myocardial reperfusion than the other two methods.

Objective To study the protective effects of curcumin on LPS-induced acute renal injury to offer the clinical evidence of treatment in mice. Methods Fifty-two mice were randomly divided into 3 groups, the control group (n=12), the LPC group (n=20) and the treated group (LPS + curcumin group, n=20). LPS (5 mg/kg) was injected intraperitoneally into the mice of the LPS group. Curcumin (20 mg/kg) was injected intraperitoneally after an intraperitoneal injection of LPS (5 mg/kg) to the mice of the treated group. The TNF-? level of the renal tissue, the serum level of urea nitrogen (BUN) and serum creatinine (Cr) were determined in 3, 6, 12 and 24 h after injection. The expression of TLR2 mRNA was detected with semi-quantitative RT-PCR and the histopathological changes of the kidneys were studied. Results The TNF-? level of renal tissue and the serum levels of BUN and Cr were significantly increased in 3 h after injection in the LPS group and reached the peak at 6 h. The significant increase of the parameters lasted for 24 h. The changes of the expression of TLR2 mRNA were similar to those of TNF-?, BUN and Cr. The histopathological changes of the kidneys included renal tubular necrosis and detachment, formation of casts, glomerular ischemia and shrinkage and infiltration of large amount of PMN in LPS group. In the theated group, the tissue level of TNF-?, the serum levels of BUN and Cr and the expression of TLR2 mRNA were significantly decreased in 3, 6 and 12 h after injection and the histopathological changes were obviously alleviated. Conclusion Curcumin can alleviate LPS-induced acute renal injury and exerts good protection on the functions of the kidneys.

Objective To investigate clinical feature,diagnosis and prognosis of eosinophilic gastroenteritis(EG),and to analyze the causes of misdiagnosis.Methods Eleven children diagnosed as EG were studied.Their history,clinical manifestations,laboratory tests and endoscopies and treatment,follow-up data were analyzed.The data were analyzed by SPSS 10.0 software.Results 1.The children with EG usually had abdominal pain(5 cases),diarrhea(7 cases),hemafecia(5 cases) and sometimes with fever(2 cases).2.EG and allergy in children was closely related with disease(54.55%).3.Peripheral blood eosinophil(EOS) count increased significantly,and declined when symptoms eased(18.18%).4.Endoscopic manifestations were not specific,the mucosa could see sheet erosion,shallow ulcers,congestive spots or bleeding spots,mainly in antrum,duodenum,terminal ileum,ileocecal junction.The biopsy showed that a large number of EOS infiltration.5.Imaging were not specific,CT or gastrointestinal barium meal examination did not show special often(90.91%).When muscular wall was affected(9.09%),imaging presentations of EG could be partly obstructive.6.Glucocorticoid therapy could relieve symptoms and EOS.Symptoms probably recured by good prognosis.7.EG was a self-limiting allergic diseases,although the attack may be repeated.After long-term follow-up,most had good prognosis and without malignant.Conclusions Clinical and endoscopic presentations of EG are not specific,therefore the presence of EOS in gastrointestinal mucosa strongly indicate the diagnosis.It was easy to misdiagnosis.Biopsy pathology and cli-nical characteristics are the key to diagnosis.

AIM To explore the effect of hypoxia on apoptosis in human umbilical vein endothelial cells(HUVECs) and the role of ecdysterone(EDS)in inhibition of apoptosis. METHODS ① Culture and identification of HUVECs;② Hypoxic model(0,12,24,48 h) in HUVECs was established. While HUVECs was incubated 24 h with EDS(100 mg?L -1 ) under hypoxic condition. Apoptosis in HUVECs was detected by TUNEL;③ HUVECs received EDS 100 mg?L -1 in normal and hypoxic condition. After 24 h, vascular endothelial growth factor (VEGF) was detected with immunohistochemical technique. RESULTS The apoptosis percentages are different under different hypoxic condition. The longer hypotic the time was, the higher the apoptosis percentage was. EDS reduced apoptosis of HUVECs. EDS could enhance expression of VEGF protein in cardiac myocytes of rat in normal and hypoxic condition. CONCLUSION The role of hypoxia in HUVECs apoptosis is more significant along with prolonging of hypoxic time. VEGF play an important role in protective effect of EDS on endothelial cell apoptosis.

Objective To investigate the relationship between helicobacter pylor (Hp) and primary carcinoma of the gallbladder (PCG), providing a theoretical basis for the treatment of PCG.Methods Mucosa and bile of gallbladder samples were collected from 18 patients with PCG (PCG group), 40 patients with chronic cholecystitis or cholelithiasis (CC group), and 20 patients with no PCG and CC (control group). 16S rDNA-based polymerase chain reaction (PCR) followed by DNA sequence analysis of the obtained PCR fragments was performed. A developed search for Hp was also carried out by PCR. Five genes specific for Hp were amplified. Results In the PCG group, 81% samples of mucosa and bile were positive for Helicobacter-specific 16S rRNA gene. The positive rate in PCG group was significantly higher than those of the CC group (50%) and the control group (20%).Of the 16S rDNA sequence of Helicobacter pylori positive samples of mucosa and bile, 52% of samples were positive in cagA, 86% were positive in 26 KDa, 48% were positive in ureA separately. The vacA and rps4 genes were never detected in any of the samples of mucosa and bile. At least one gene was positive in 93% of samples of musca and bile. The sequencing showed more than 99% homology of Helicobacter 16S rRNA in PCG and Hp groups. Conclusion A higher infection rate is present in bile and gallbladder mucosa from patients with PCG. Hp in the biliary system may be one of the risk factors for occurrence of PCG.
