Objective To evaluate the relationship between lifestyle and development of Alzheimer's disease(AD).Methods Two hundred and thirty-eight AD patients(102 males and 136 females) and 476 healthy controls(204 males and 272 females) were recruited from Ningbo communities into this 1 ∶ 2 matched case-control study.Mini-Mental State Examination(MMSE) and Clinical Dementia Rating(CDR) were required to fill in.Chi-square test and conditional logistic regression were used for data analysis.We adopted Epidata 3.1 to establish the database and did statistical analysis by SPSS15.0.The count data were analysis by Chi-square test,meanwhile multiple factors analysis by conditional Logistic regression analysis.Results Through single factor analysis we found thatcigarette ≥20/day(F=8.687,P=0.003),children visiting(F=22.721,P＜0.05),friendship(F=16.784,P＜0.05),family gathering(≥1 times/week)(F=8.198,P=0.004),working after retirement(F=33.099,P＜0.05),travel(F=16.784,P＜0.05),social activities(F=24.919,P＜0.05),physical exercises(F=24.404,P＜0.05),eating pickles or pickled products(F=6.662,P=0.01),saturated fatty acid intake(F=23.069,P＜0.05),daily consumption of fruits and vegetables(F=8.401,P=0.004),chess(F=17.365,P＜0.05),reading(≥30 min/d)(F=36.390,P＜0.05),using computer(F=8.688,P=0.003) were related AD,the difference was statistically significant(P＜0.05).In multiple factors analysis,social activities,chess games or joke,travelling,working after retirement,reading,physical exercises,friendship,family gathering,saturated fatty acid intake and daily consumption of fruits and vegetables were risk factors of AD(odds ratio(OR) values were 0.571(0.342-0.753),0.623(0.343-0.889),0.686(0.461-0.942),0.534(0.326-0.714),0.276(0.175-0.438),0.538(0.336-0.738),0.585(0.385-0.765),0.466(0.316-0.745),0.527 (0.368-0.787) and 0.482(0.316-0.665),respectively; constant terms:OR=0.526).Conclusion A positive and leisure lifestyle and health reasonable diet could effectively reduce the risk of AD.

Objective:To evaluate the influence of prophylactic intra-coronary injection nitroglycerin with diltiazem in patients of acute ST segment elevation myocardial infarction(STEMI) Methods:This study was conducted in 212 patients with acute STEMI who underwent primary percutaneous coronary inter- vention(PCI)in our center from January 2001 to December 2006.The patients were randomly assigned to receive intra-coronary nitroglycerin with dihiazem(n = 87)or none of them(125)before intervention.The clinical data,coronary angiography data after intervention,ST-segment resolution,area under the curve of CK-MB,ejection fraction(EF)and left ventricular end-diastolic di- mension several days alter operation and the major adverse cardiac events(MACE)were analyzed systemically. Results:Ten(11.5%)patients in study group and 28(22.4%)in control group had MACE(P = 0.042).The difference of re-hospitalization was also significant(19.5% vs 37.6%,P = 0.008).No/slow reflow occurred less in study group than in con- trol group,but the difference was not significant.Corrected TIMI frame count was lower(34.4?11.3 vs 38.9?17.2,P = 0.034) and myocardial blush grade was higher(2.65?0.6 vs 2.41?0.7,P =0.018)in study group.ST-segment resolution,area under the curve of CK-MB in 5 days after operation,EF and left ventricular end-diastolic dimension in study group were more significant than those in control group(P

Objective To investigate the role of Glial cells missing 2 (Gcm2) in pathogenesis of hypoparathyroidism by knocking out Gcm2 gene in adult mice.Methods Tamoxifen was used to induce conditional knock-out of Gcm2 gene in Gcm2E2fl/flCre-ER mice.Genotypes of knock-out mice were identified by PCR.The protein expression level of Gcm2 was measured by Western blotting.The serum calcium and phosphorus were detected by the calcium and phosphorus assay kits, and the serum parathyroid hormone (PTH) level was detected by ELISA.Parathyroid cell proliferation was tested by Ki-67 immunohistochemical assay.The mRNA expression levels of PTH and calcium sensing receptor (CaSR) were detected by Real-time PCR.Bone mineral density was detected by micro CT.Results Gcm2 gene of parathyroid was confirmed to be knocked out by PCR.Compared with wild type and solvent control groups, Gcm2 knock-out group showed markedly lower protein expression of Gcm2, notably higher serum phosphorus and lower serum calcium and PTH concentrations (all P<0.01).The proliferation of parathyroid cells in Gcm2 knock-out mice were significantly higher(both P<0.01).The mRNA levels of PTH and CaSR in parathyroid gland of the knock-out group were significantly reduced (all P<0.01).Bone mineral density was significantly higher in Gcm2 knock-out group (all P<0.01).Conclusion Knockout of Gcm2 can lead to hypoparathyroidism in adult mice, indicating that Gcm2 is probably a therapeutic target for hypoparathyroidism.

Objective:To analyze and compare difference of ultrasonic blood flow of left internal mammary artery(LIMA) and right internal mammary artery(RIMA)as graft to left anterior descending artery(LAD) in patients undergoing off-pump coronary artery bypass grafting(OPCABG).Methods:From October 2017 to October 2019, a total of 363 patients who underwent OPCAB including 329 patients in LIMA-LAD group and 34 patients in RIMA-LAD group, were included in this study. Transthoracic ultrasound examination on IMA was performed before OPCABG. The blood flow , the value of PI(pulsation index) and diastolic flow(DF) of LIMA and RIMA to left anterior descending were measured and recorded by intraoperative TTFM. Patients underwent coronary artery CT examinations at 1 week after OPCABG to discover the patency of grafts.Results:The pre-operative diameter of RIMA was larger and the blood flow and pulsation index of RIMA was better than that of LIMA before OPCABG( P<0.001). But there was no significant difference in the flow, pulsation index and DF value of graft between the two groups after IMA were anastomosed to LAD( P>0.05). In situ skeletonized graft of RIMA did not show the advantage of increased blood flow. Compared with the preoperative parameters of flow of internal mammary artery, both the left and right grafts of IMA were significantly better in blood flow and pulsation index( P<0.001). Considering the remarkable difference in age between the two groups, Flow, PI and DF were compared again after propensity score matching, and there was still no statistical difference between the two groups( P>0.05). A total of 313 patients in LIMA-LAD group completed coronary CTA examination one week after surgery, among which 4 grafts had different degrees of problems. A total of 34 patients in RIMA-LAD group completed coronary CTA examination, one case indicated that the CTA imaging in distal segment was not clear, and the other results had no obvious abnormality. There was no significant difference in postoperative rate of coronary CTA completion( P=0.381) and rate of graft failure( P=0.405) between the two groups. Conclusion:Compared with the preoperative parameters of blood flow of internal mammary artery, both the left and right IMA grafts are significantly better in flow and pulsation index. The pre-operative diameter of RIMA is larger and the blood flow and pulsation index of RIMA is better than that of LIMA before OPCABG. But there is no significant difference in the flow, pulsation index and DF value of graft between the two groups after IMA are anastomosed to LAD. In situ skeletonized graft of RIMA do not show the advantage of increased blood flow.

Objective To summarize the experience on the diagnosis and therapy of intravenous leiomyomatosis(IVL)of the inferior vena cava.Methods Eight IVL patients were treated in our hospital from March 1998 to April 2007. Results The diagnosis of IVL of the inferior vena cava was established histologically by biopsy during inferior vena eavagram before operation in 4 patients.Seven patients received open surgery.Except one patient dying of massive hemorrhage during operation and one IVL recurrence during follow-up,postoperative course was uneventful and an average follow-up of 29 months found no recurrence in the other five patients. Conclusion The final diagnosis of IVL of the inferior vena cava depends on venogram and biopsy,and it is an estrogen dependent tumor originating from uterus leiomyoma.Total surgical extirpation of the tumor is the only effective treatment for IVL.
