Objective To understand the prevalence and Influencing factors of Metabolic Syndrome(MS) of 40～74 year-old non-diabetes population in Minhang District.Methods A population-based sample(diabetes screening of Minhang District in 2007) of 3 947 individuals aged 40～74 years was investigated by cluster random sampling.They completed a questionnaire and underwent triglyceride,high density lipoprotein measured cholesterol and an oral glucose tolerance test.Results The standardized prevalence rate of MS,overweight,diabetes,impaired glucose regulation(IGR),hypertension,high triglyceride and low HDL were 15.67%,2.45%,5.60%,17.72%,16.47% and 2.00%.The male with MS,overweight or obese,diabetes and hypertension were higher than the female in terms of incidence.The prevalence of MS was increased with age,the highest rate at the ages of 50 years and above.There was no significant difference between male and female at the ages of 45 years and above.The incidence of MS in people with BMI or hypertension or abnormal blood glucose or hige TG or low HDL-C was obviously higher than that of normal population.The OR value were 15.71,28.21,10.09,30.31 and 3.14 respectively.The prevalence of diabetes,coronary heart disease and stroke in people with MS was higher than that of people with out MS.The OR value were 10.09,9.94 and 2.40.Multiple factor analysis showed that the factors related to MS were male,the aged,family history of diabetes and having no physical activity.Conclusions MS and realated diseases are a serious threat to population of 40 years old and above in Minhang District.

Objective To explore the relationship of monocyte chemoattractant protein-1(MCP-1)and oxygen-induced retinopathy(OIR).Methods Thirty-six newborn SD rats were divided into 2 expanded litters,18 of which were exposed to 50 mL/L oxygen and then 10 mL/L oxygen in alternating 24-hour periods(experiment group),an additional 18 rats as control rats were raised simultaneously in room air(control group).On postnatal 14 days(P14),oxygen-exposed rats were removed to room air.The eyeballs of 6 rats from each group were enucleated and fixed by formaldehyde at postnatal 14 days(P14),postnatal 17 days(P17),and postnatal 21 days(P21)respectively,and then cross sectioned.The nuclei of proliferative retinal vessels were counted through the crosssections to measure the average retinal capillary density index(RCDI)when stained with hematoxylin and eosin(HE)under light;the expression of MCP-1 was measured by immunohistochemistry.Results There existed obviously differencc between 2 groups in the field of both RCDI and the expression of MCP-1 at the same time point [t(P14)=6.69 P=0.001,t(P17)=3.43 P=0.006,t(P21)=2.37 P=0.039;t(P14)=40.45,t(P17)=43.44,t(P21)=17.45 Pa=0],when RCDI and the expression of MCP-1 were compared among the different time points with in the same group,there existed obviously difference among three time points in the experiment group(F=17.74 P=0.0001;F=421.5 P=0),but no differencc in control group(F=0.016 P=0.984;F=0.006 P=0.994).There existed positive correlation between the expression of MCP-1 and the value of RCDI in experiment group(r=0.822 P=0).Conclusions Neovascularization resulting from OIR occurs before room air recove-ry.MCP-1 is upregulated and subsequently downregulated in OIR.Neovascularization in the OIR model appear to be associated with increased retinal MCP-1.

Objective To explore ultrasound performances and misdiagnostic causes of aggressive fibromatosis (AF).Methods Ultrasound performance and misdiagnostic causes of 45 patients (47 tumors) with AF confirmed by histopathology were analyzed retrospectively.Results Of 45 patients,ultrasound showed lesions of varying size,and the maximum diameter of 36 masses (36/47,76.60％) were more than 3 cm;37 masses (37/47,78.72％) were irregular pale leaf;45 masses (45/47,95.74％) had no complete capsule;45 masses (45/47,95.74％) were shown as interogeneous internal echo mixed with hyperechoic area in the hypoechoic internal;29 cases were diagnosed correctly,16 cases were misdiagnosed,the diagnostic accordance rate was 64.44％ (29/46).Conclusion AF has certain ultrasonic characteristics.Combined with the patient's medical history and physical sign,ultrasound can significantly improve the preoperative detection rate and diagnostic accuracy of AF.

BACKGROUND:Synthetic patch as an important substitute to pelvic tissue can replace damaged pelvic fascia tissue, and has been widely used in the pelvic floor reconstruction. OBJECTIVE:To observe the efficacy and complications of pelvic floor reconstruction with mesh, and to explore its safety and effectiveness. METHODS: Forty-five pelvic organ prolapse female patients were divided into two groups according to patient’s wilingness: experimental group, pelvic floor reconstruction with mesh (n=25); control group, transvaginal hysterectomy combined with vaginal wal repair (n=20). Perioperative conditions were recorded, and uterine prolapse staging, complications, pelvic floor function, pelvic discomfort, as wel as an objective cure rate were evaluated in the two groups during the folow-up. RESULTS AND CONCLUSION:Compared with the control group, the experimental group was characterized as shorter operative time, less amount of bleeding, milder infections, and faster recovery (AlP < 0.05). At 6 months of folow-up, the score on uterine prolapse staging was higher in the experimental group than the control group; at 12 months, the scores on pelvic floor function and pelvic discomfort as wel as the incidence of complications were significantly lower in the experimental group (P < 0.05), but the objective cure rate was higher compared with the control group (P < 0.05). These findings suggest that pelvic floor reconstruction with mesh for pelvic organ prolapsed can reduce the operative time and blood loss and promote postoperative recovery. Meanwhile, it can significantly improve pelvic floor function, pelvic discomfort, postoperative complications, the rate of exposure, and the objective cure rate, which is safe and effective during the short-term folow-up.

Objective To discuss the value of high resolution MRI in the evaluation of small intralabyrinthine lesions with the symptom of vertigo. Methods We retrospectively analyzed the imaging examination techniques and imaging finding of 13 cases of labyrinthine hemorrhage or exudate and 6 cases of intralabyrinthine schwannoma (ILS) with the symptom of vertigo. Two cases of labyrinthine hemorrhage or exudate and 3 cases of ILS underwent temporal bone high resolution CT(HRCT) scan and all the 19 patients received highresolution MR examination. Patients of labyrinthine hemorrhage or exudate received fluid?attenuated inversion recovery (FLAIR)T2WI in addition to routine pre?contrast temporal bone MR. Pre?and post?contrast MR of the temporal bone were performed on the ILS patients. In particular, 3 ILS cases received three?dimensional sampling perfection with application?optimized contrasts by using different flip angle evolutions (3D?SPACE) sequence. Results There was no abnormal finding on HRCT of the inner ear of the 2 labyrinthine hemorrhage cases. On T1WI, regions of mild increased signal intensity of the labyrinth of affected side could be spotted in 7 patients whereas no abnormal signal intensity was found in the other 6 patients. On T2WI, all the 13 labyrinthine hemorrhage or exudate cases had no abnormal finding in the inner ear. On FLAIR T2WI sequence, regions of increased signal intensity of the labyrinth of affected side could be found in all the 13 cases. Thress ILS patients that received HRCT scan showed no valuable finding. On T1WI, no abnormal signal intensity was found in the labyrinth of the 6 patients. On T2WI, regions of decreased signal intensity of the labyrinth could be found in only 3 patients. All the 3 cases that received 3D?SPACE sequence appeared as a filling defect in the high?signal labyrinth clearly while 2 of the 3 lesions could not be found on T2WI. After Gadolinium administration, all the 6 ILSs were obviously enhancing. Conclusions High resolution MRI is valuable in the diagnosis of labyrinthine hemorrhage or exudate and ILS. The use of FLAIR T2WI sequence can help us to find labyrinthine hemorrhage or exudate more sensitively. The use of 3D?SPACE sequence can help us to detect and diagnose small intralabyrinthine lesions.

BACKGROUND:Genetic factors, environment, chronic infection, and autoimmune disorders are considered to be involved in the pathogenesis of ankylosing spondylitis. Genetic factors play an important role in the pathogenesis of the disease. Ethnic and regional diversity of differentialy expressed genes has become research hotspot because of family aggregation and ethnic diversity of ankylosing spondylitis.
OBJECTIVE:To screen differentialy expressed genes in Xinjiang Uygur and Han patients with ankylosing spondylitis by microarray screening and compare differences in gene expressions.
METHODS: Uygur and Han patients with active ankylosing spondylitis in department of rheumatology of our hospital were randomly colected with five patients for each. In addition, three healthy volunteers were selected as controls. RNA from peripheral blood was extracted and used for microarray hybridization after probe preparation to screen differentialy expressed genes in ankylosing spondylitis samples and the microarray results were verified by semi-quantitative RT-PCR analysis.
RESULTS AND CONCLUSION: Twenty differentialy expressed miRNAs were screened in Uygur and Han patients with active ankylosing spondylitis (P < 0.05). From relationship analysis of target genes and miRNAs, 15 target genes corresponding to the 79 miRNAs involved in human leucocyte antigens and interleukins which linked to human immunity system were found. These findings suggest that differentialy expressed genes can be screened from Uygur and Han patients with ankylosing spondylitis.

Objective Resarech on the correlation between serum tumor markers CA19-9,CEA,CAS0 and the early diagnosis and staging of pancreatic cancer.Methods To compare the serum levels of the CA19-9,CEA,CA50 in 51 patients with pancreatic cancer,10 benign tumor patients and 12 chronic pancreatitis patients admitted to the Department of general surgery,Anhui Provincial Hospital from January 2013 to October 2015.Results CA19-9 expression in different stages of pancreatic cancer and other pancreatic diseases were statistically significant (P ＜ 0.05).The difference of CEA and CA50 expression in pancreatic cancer and other pancreatic diseases was statistically significant (P＜0.05).But the CEA in stage Ⅰ and stage Ⅱ,stage Ⅰ and stage Ⅲ,stage Ⅱ and stage Ⅲ patients with clear expression of the difference was not statistically significant (P ＞ 0.05).The was no significant difference in the expression of CA50 in pancreatic cancer stage Ⅰ and stage Ⅱ,Ⅲ and Ⅳ (P ＞ 0.05).The positive rate of CA19-9 in the diagnosis of pancreatic cancer was higher than that of CEA and CA50.The positive rate of CA19-9,CEA,CAS0 and were the highest in the diagnosis of pancreatic cancer.Conclusions The expression levels of CA19-9,CEA and CA50 in serum have a certain relevance to the early diagnosis of pancreatic cancer,and the value of CA19-9 is the highest in the stage of pancreatic cancer.

Objective: To study the examination of coronary sinus (CS) and blood flow by transthoracic echocardiography(TTE) and transesophageal echocardiography(TEE).Methods: Thirty patients with supraventricular tachycardia were studied by TTE and TEE. The CS was visualized using modified 4 chamber view. The position of the probe was optimized until the coronary sinus with its ostium into the right atrium could be visualized. CS flow recordings were performed by TEE with Doppler sample volume placed in the CS within a distance of no more than 10 mm from its ostium. Results: In all patients the angle between the doppler beam and the long axis of the CS was <30°. The CS was fully displayed in 18 patients by TTE and 28 patients by TEE. The length and width of the CS were (16.53±2.57) mm and (4.51±1.30) mm by TTE, (24.11±2.46) mm and (5.06±0.97) mm by TEE.The CS flow was characterized by biphasic flow.Its flow velocity was (39±7.8), (31±6.1) and (21±4.7) cm/s respectively. The CS flow velocity-imeintegral was(43±11.6),(43±13.0),(27±8.2) cm/s. Conclusion: Echocardiography is reliable for detecting CS and its flow. TTE is more feasible for detecting CS and its flow than TEE.
