Interarterial subtype of coronary artery with anomalous aortic origin is a rare and congenital cardiovascular malformation,manifested by chest pain and syncope after exertion or activity,which can lead to decreased cardiac contractility,myocardial infarction,and even sudden death.Here we report a case of an adolescent patient,who presented with chest pain during activity accompanied by syncope and lost consciousness.Initially diagnosed with acute myocardial infarction,the patient was subsequently diagnosed as interarterial subtype of a coronary artery originating from anomalous aorta after echocardiography,coronary angiography,coronary CT angiography examinations.After anomalous coronary artery correction and coronary angioplasty,the paitent recovered well.

Objective: To evaluate the effectiveness for the construction of "mosquito-free village" in Xuejia Village, Pujiang County, Zhejiang Province, so as to provide the guidance for the construction of "mosquito-free village" in other rural areas. Methods: Density of adult mosquitoes in Xuejia Village was investigated using light trap method and density of larval mosquitoes was investigated using larval straw method from April to November each year. Totally 30 households of villagers were randomly selected, and their awareness rates of mosquito control knowledge, mosquito control behavior forming rates and satisfaction rates were surveyed through questionnaires. Investment during construction (from August 2016 to December 2018) and maintenance period (from 2019 to 2023) of "mosquito-free village" were investigated through data review and interviews. Long-term effects of "mosquito-free village" construction in Xuejia Village were evaluated in terms of mosquito density from 2016 to 2023, effectiveness of health education for villagers, satisfaction and investment. Results: Compared with the year 2016, the densities of adult and larval mosquitoes in Xuejia Village were significantly decreased from 2017 to 2023. The average monthly density of adult mosquitoes in 2023 decreased by 98.34%, and the average monthly 100 household index of larval mosquitoes decreased by 98.45% compared to 2016. The average monthly density of adult mosquitoes from 2019 to 2023 was less than or equal to one mosquito per light trap in a night, and the average monthly 100 household index of larval mosquitoes was less than or equal to five places per 100 households. The awareness rate of mosquito control knowledge was 93.33%, the behavior forming rate was 86.67%, and the satisfaction rate was 90.00%. By December 2023, the total investment during construction and maintenance period was 450 thousand Yuan, with an average annual investment of 60.7 thousand Yuan and average annual investment of 206.61 Yuan per household. The average annual investment during maintenance period was 36.2 thousand Yuan, and the average annual investment per household was 109.70 Yuan. Conclusion The mosquito density, effectiveness of health education for villagers and satisfaction of "mosquito-free village" in Xuejia Village all meet the evaluation criteria of "mosquito-free village", and the investment is reasonable, making it suitable for promotion to other rural areas.

In early stage after liver transplantation(LT), coagulation function of recipients stays in a fragile balance. Affected by a variety of complex mechanisms, blood is usually hypercoagulable. An imbalance between coagulation factors and physiological anticoagulants, elevated level of vWF, an occurrence of fibrinolysis inhibition and dosing of immunosuppressive agents cause a hypercoagulable state in an early stage after LT. Blood hypercoagulability may lead to such thrombotic complications as hepatic artery, portal vein and deep vein thromboses. Some studies have demonstrated that postoperative prophylactic anticoagulation has some effect in reducing the risks of early postoperative thrombosis. However, there is still a great lack of high-quality evidence. This review summarized the latest researches on early coagulation dysfunction, thrombosis and preventive anticoagulation after LT.

Objective To determine the epidemiological and etiological characteristics of hand，foot，and mouth disease （HFMD） in Pujiang County from 2008 through 2020， so as to provide scientific evidence for prevention and control measures. Methods Descriptive epidemiological analysis was used to analyze HFMD cases retrieved in the Chinese Information System for Disease Control and Prevention in Pujiang County during 2008‒2020. Results From 2008 through 2020， a total of 9 393 cases were documented in Pujiang County， with an annual incidence of 182.3 per 100 000， showing a trend of alternating high-incidence and low-incidence years. The seasonal distribution was bimodal， and the incidence peaked in May-July and November-December. The incidence of HFMD in urban areas was significantly higher than that in rural areas， and the incidence was positively correlated with population density. Majority of cases （94.9%） were children under 5 years old， of which boys had higher incidence than girls. The number of documented cases was the highest among preschool children living in families and kindergartens， accounting for 97.3%. Totally， 558 cases were laboratory confirmed in Pujiang County in 2008-2020， of which severe cases were all caused by EV71 infection. Conclusion Enterovirus serotypes in HFMD have continually changed from 2008 through 2020 in Pujiang County. However， severe HFMD remains principally attributable to EV71 infection， suggesting that it is necessary to strengthen the surveillance on the etiology of HFMD. In addition， it warrants further promotion of EV71 vaccination.

OBJECTIVETo investigate the effect of smoking cessation on the risk of cancer among male subjects.

METHODSParticipants of this study were derived from the workers in Kailuan Group who took the health check-up examination in its 11 affiliated hospitals. The check-up examinations were given biennially based on uniformed standard. From May 2006 to December 2011, health examinations were given for 3 rounds and a total of 104 809 male workers involved. The date of being enrolled in this study was defined as that of taking first check-up, and the date of end-of-observation was defined as that of cancer diagnosis, death or end of follow-up.

INCLUSION CRITERIAage ≥18 while being enrolled in this study, and there was no information missing in the questionnaire for age (or date of birth), smoking status, the age of starting smoking, the age of quitting smoking, and smoking amount. The information of smoking status was collected by questionnaires, and the information of newly-diagnosed cancer cases was obtained by follow-up. After adjusted for age, education background, drinking habits, working environment and BMI, multi-variate Cox proportional hazard regression models were used to analyze the association between smoking cessation and cancer risk (all sites of cancers, smoking-related cancers, and lung cancer) by calculating the values of HR (hazard ratio) and 95% CI (confidence interval).

RESULTSTotally, 104 809 subjects were followed up for 450 639.6 person-years, including 46 013 smokers (43.90%), 51 624 never-smokers (49.26%), and 7 172 smoking quitters (6.84%). Among all these subjects, 1 323 were diagnosed as cancer cases, including 1 082 smoking-related cancers, of which 378 were lung cancer cases. The results showed that, compared with never-smokers, smokers had increased risks for all sites of cancers (HR=1.38, 95% CI: 1.20- 1.59), smoking-related cancers (HR=1.45, 95% CI: 1.24- 1.69) and lung cancer (HR=1.70, 95% CI: 1.31- 2.21). While compared with the smokers, smoking quitters had decreased risk of lung cancer (HR=0.36, 95% CI: 0.20- 0.65). For the smokers with smoking history ≥20 pack-years, HR (95% CI) of lung cancer incidence was 0.09 (0.01- 0.65). For people age ≥60 smoke quitter, HR (95% CI) of lung cancer incidence was 0.33 (0.16- 0.68). For people who quit ≥10 years, HR (95% CI) of lung cancer incidence was 0.19(0.06- 0.58).

CONCLUSIONSmoking cessation might decrease the risk of lung cancer among male smokers. The risk of lung cancer was lower among the smoking quitters with longer history of smoking, older age, and longer years of quitting smoking.

This study examined the association of polymorphisms in angiotensin Ⅱ receptor genes (AT1R and AT2R) with the risk for aldosterone-producing adenoma (APA) in a Chinese Han population.Four polymorphisms including rs5182 (573T/C) in exon 4,rs5186 (1166A/C) in 3'-untranslated region (3'-UTR) in AT1R gene and rs5194 (2274G/A) in 3'-UTR,rs1403543 (1675G/A) in intron 1 in AT2R gene were detected in 148 APA patients and 192 normal subjects (serving as control) by using a MGB-Taqman probe.The distribution of genotypes of each locus was in accordance with Hardy-Weinberg Equilibrium (HWE) in the APA and control groups (P＞0.05).The allele A frequency at rs5194 was significantly higher in the APA group (0.49) than in the control group (0.35) (X2=12.08,P=0.001).Subjects with homozygotic genotype AA and heterozygotic genotype GA were at an increased risk for APA as compared to those with GG genotype (OR=2.66,95％ CI=1.45-4.87; OR=1.67,95％ CI=1.02-2.74).Furthermore,rs5194 single-nucleotide polymorphism (SNP) at AT2R gene was significantly associated with APA in additive (OR=1.64,95％ CI=1.21-2.20,P=0.001),dominant (OR=1.94,95％ CI=1.23-3.06,P=0.003),and recessive model (OR=2.01,95％ CI=1.17-3.45,P=0.01).It was concluded that rs5194 polymorphism at AT2R gene was associated with the risk for APA,which may constitute a genetic marker of APA.

This study examined the association of polymorphisms in angiotensin II receptor genes (AT (1) R and AT (2) R) with the risk for aldosterone-producing adenoma (APA) in a Chinese Han population. Four polymorphisms including rs5182 (573T/C) in exon 4, rs5186 (1166A/C) in 3'-untranslated region (3'-UTR) in AT (1) R gene and rs5194 (2274G/A) in 3'-UTR, rs1403543 (1675G/A) in intron 1 in AT (2) R gene were detected in 148 APA patients and 192 normal subjects (serving as control) by using a MGB-Taqman probe. The distribution of genotypes of each locus was in accordance with Hardy-Weinberg Equilibrium (HWE) in the APA and control groups (P>0.05). The allele A frequency at rs5194 was significantly higher in the APA group (0.49) than in the control group (0.35) (χ (2)=12.08, P=0.001). Subjects with homozygotic genotype AA and heterozygotic genotype GA were at an increased risk for APA as compared to those with GG genotype (OR=2.66, 95% CI=1.45-4.87; OR=1.67, 95% CI=1.02-2.74). Furthermore, rs5194 single-nucleotide polymorphism (SNP) at AT (2) R gene was significantly associated with APA in additive (OR=1.64, 95% CI=1.21-2.20, P=0.001), dominant (OR=1.94, 95% CI=1.23-3.06, P=0.003), and recessive model (OR=2.01, 95% CI=1.17-3.45, P=0.01). It was concluded that rs5194 polymorphism at AT (2) R gene was associated with the risk for APA, which may constitute a genetic marker of APA.

Objective To study the role of fibulin-5 in urothelial carcinoma of bladder. Methods Fibulin-5 expression was detected in bladder cancer tissues (13 cases of G_1 and G_2, 7 cases of G_3) and normal bladder mucosa samples by Western blotting assay. Fibulin-5 cDNA was amplified by PCR and cloned into pMD-19T simple vector. The pMD-19T-Fibulin-5 vector was digested by restriction endonucleases XhoI and EcoRI to generate a XhoI-Fibulin5-EcoRI fragment that was then ligated into the identical sites in p-EGFP-Nl plasmid to synthesize p-EGFP-Fibulin-5 plasmid. The p-EGFP-Fibulin-5 plasmid was finally transfected into bladder cancer cell line 5637. The migration and invasion of untransfected, vector-transfected and fibulin-5-transfected bladder cancer cells were measured by Boyden chamber assay. Results Compared to 1. 16 ±0. 28 in the normal control, the expression of fibulin-5 protein in low grade and high grade tumors were 0. 57±0. 32 and 0. 44±0. 42(P<0. 01, respectively). However, the difference between low grade and high grade tumors was not statistically significant (P>0. 05). The successfully transfected bladder cancer cells demonstrated green fluorescent light. The migrated cell number of fibulin-5-transfected cells was 127. 6 ± 3. 1 compared with 139. 3±7. 7 for vector-transfected cells and 136. 9±5. 7 for untransfected cells (P>0. 05, respectively). In contrast, the invaded cell number of fibulin-5-transfected cells was 8. 0±3. 1 compared with 31. 5±4. 8 for vector-transfected cells and 31. 7±4. 7 for untransfected cells (P<0. 01, respectively). Conclusion Fibulin-5 is down-regulated in urothelial carcinoma of bladder and acts as a tumor suppressor gene by inhibiting the invasion of bladder cancer cells.

This study aimed to determine whether aldosterone could induce vascular cell apoptosis in vivo.Thirty-two male rats were randomly divided into 4 groups: vehicle(control),aldosterone,aldosterone plus eplerenone or hydralazine.They were then implanted with an osmotic mini-pump that infused either aldosterone or the vehicle.Systolic blood pressure(SBP)was measured weekly by the tail-cuff method.After 8 weeks,plasma aldosterone concentration(PAC)and renin activity(PRA)were determined by radioimmunoassay.Aortic apoptosis was examined by TUNEL assay.The levels of cytochrome c and caspase-3 were determined by Western blotting and the expression of Bax and Bcl-2 was detected by immnuohistochemistry and Western blotting.The results showed that as compared with control group,aldosterone-infused rats exhibited:(1)an increase in SBP;(2)significantly elevated PAC with depressed PRA;(3)elevated aortic vascular cell apoptosis accompanied with higher levels ofcytochrome c and activated caspase-3; and(4)significantly up-regulated Bax protein with down-regulated Bcl-2.These effects of aldosterone were significantly inhibited after co-administration with eplerenone but not with hydralazine.It was concluded that aldosterone inducedvascular cell apoptosis by its direct effect on the aorta via mineralocorticoid receptors and independently of blood pressure,which may contribute to aldosterone-mediated vascular injury.

The expression of angiotensin Ⅱ type 1 receptor(AT1R)and angiotensin Ⅱ type 2 receptor (AT2R)in aldosterone-producing adenoma(APA)of the adrenal gland was detected,and their relationship with clinical indexes of APA was analyzed.The mRNA expression of AT1R and AT2R in50 cases of APA and tissues adjacent to tumors and 12 cases of normal adrenal tissues was detected by using reverse transcriptase polymerase chain reaction(RT-PCR).The expression of AT1R and AT2R proteins in paraffin-embedded slices of tissue was detected by immunohistochemistry.The expression of AT1R in adenoma,tissues adjacent to tumor,and normal tissues of the adrenal gland showed no significant differences.The expression of AT2R in APA tissue was lower than that in normal adrenal gland tissues(P<0.05).Correlation analysis of the mRNA expression level of AT2R and clinical data from patients demonstrated that AT2R expression was negatively related to plasma aldosterone concentration(PAC)(r=-0.467,P<0.05),but positively related with plasma renin activity(PRA)(r=0.604,P<0.05).It is concluded that down-regulation of the AT2R expression is possibly related with the tumorigenesis of APA.
