ABSTRACT
ObjectiveTo explore the relationship between snoring and hypertension in middle-aged and elderly residents in Yangpu District， Shanghai. MethodsThe data of this study were obtained from the project of “early screening and comprehensive intervention for high-risk of cardiovascular diseases” carried out by the National Cardiovascular Disease Center in Yangpu District in 2017. Questionnaire survey， physical examination and laboratory test were conducted among permanent residents aged 35‒75 years. Logistic regression model was used to analyze the influence of sleep snoring on hypertension. ResultsA total of 11 100 people with complete data were included in the analysis， The self-reported snoring rate of male was significantly higher than female （48.12% vs 36.21%， χ2=137.70， P<0.01）. The proportion of self-reported occasional snoring， frequent snoring and daily snoring were 14.67%（1 628/11 100）， 7.59%（843/11 100） and 17.50% （1 943/11 100）， respectively， and the prevalence of hypertension gradually increased with the increase of snoring frequency （≤60 years，male： χtrend2=51.83，P<0.01；female： χtrend2=95.01， P<0.01； >60 years， male： χtrend2=9.22， P<0.01； female： χtrend2=27.10， P<0.01）. Multivariate logistic regression analysis showed that in people aged ≤60 years， both men and women， snoring frequency was significantly associated with hypertension after adjusting for education， total family income， smoking， alcohol consumption， diabetes， body mass index （BMI） and waist circumference. In the males： occasional snoring OR （95%CI） was 1.95 （1.36，2.80）， frequent snoring OR （95%CI） was 1.55 （1.04，2.31）， daily snoring OR （95%CI） was 1.92 （1.43，2.59）. In the females： occasional snoring OR （95%CI） was 1.31 （1.08，1.59）， frequent snoring OR （95%CI） was 1.41 （1.07，1.88）， daily snoring OR （95%CI） was 1.63 （1.32，2.00）. But in people aged >60 years， the significant association between snoring frequencies and hypertension did not exist， after adjusting for education， total family income， smoking， alcohol consumption， diabetes， BMI and waist circumference. In the males： occasional snoring OR （95%CI） was 1.31 （0.97，1.78）， frequent snoring OR （95%CI） was 1.22 （0.87，1.73）， daily snoring OR （95%CI） was 1.19 （0.94，1.73）. In the females： occasional snoring OR （95%CI） was 1.06 （0.87，1.29）， frequent snoring OR （95%CI） was 1.30 （0.99，1.72）， daily snoring OR （95%CI） was 1.19 （0.97，1.46）. ConclusionIn people ≤60 years old， snoring is significantly associated with hypertension， so more attention should be paid to sleep snoring monitoring in middle-aged people for early detection of hypertension.
ABSTRACT
ObjectiveTo analyze the epidemiological characteristics of a family cluster of COVID-19 in a district of Shanghai， and to provide a scientific basis for prevention and control of cluster epidemic of COVID-19. MethodsField epidemiological survey was applied to study the cases and close contacts of a family cluster of COVID-19 in a district of Shanghai in 2021. Descriptive analysis of epidemiological survey data was conducted and real-time fluorescent quantification （RT-PCR） was used to detect new coronavirus nucleic acid for the collected specimens. ResultsCase A was the source of infection in the home aggregated epidemic. There were 2 second-generation cases infected in the whole incubation period. Case B and C were transmitted by case A through eating together. The PCR test results were negative both in the close contacts outside the family of primary contacts as well as in the close contacts to primary close contacts. ConclusionCOVID-19 is highly contagious and populations are generally susceptible. It is easy to cause family aggregated epidemic situation. Asymptomatic infection should be detected early and isolated. We should strengthen the tracking and management of close contacts of COVID-19 cases， and identify the second-generation cases as soon as possible.
ABSTRACT
Objective: To investigate the economic burden of bacillus Calmette-Guérin (BCG) lymphadenitis in Shandong Province. Methods: From May 2011 to December 2019, 304 patients applying for the province-level compensation of BCG lymphadenitis was selected from Shandong Province in this study. The basic situation, vaccination, outpatient (inpatient) records, cost and relevant information of those patients were collected to calculate the direct economic burden (including direct medical costs and direct non-medical costs), indirect economic burden and total economic burden. Comparison of the difference of economic burden of cases with different characteristics was taken. Results: The M(Q1,Q3) of age of BCG lymphadenitis patients was 3 (2, 4) months, among which 239 cases (78.6%) were male, 71 cases (23.4%) had lymphadenopathy, and 227 cases (74.7%) underwent surgery.The number of outpatient only, inpatient only and outpatient then inpatient was 25.7% (78 cases), 7.2% (22 cases) and 67.1% (204 cases), respectively. The M(Q1,Q3) of direct, indirect and total economic burden of single case after discount was 9 910 (5 713, 16 074), 2 081 (1 547, 3 122) and 12 262 (7 694, 18 571) yuan, respectively.The direct medical expenses accounted for 89.4% of the direct economic burden, the direct economic burden accounted for 84.9% of the total economic burden, the total economic burden of 80.0% cases accounted for only about 20.0% of the compensation amount, and the total economic burden of only 2.3% cases accounted for more than 60.0% of the compensation amount.The direct, indirect and total economic burden of patients with inpatient only and outpatient then inpatient was higher than that of patients with outpatient only; the direct, indirect and total economic burden of patients with operation was higher than that of patients with non-operation; the direct and total economic burden of patients with unulcerated lymph node was higher than that of patients with ulcerated lymph node(all P values<0.05). Conclusion: The economic burden of BCG lymphadenitis cases in Shandong Province is influenced by the mode of diagnosis and treatment, with direct medical expenses as the predominant component.

Objective:To analyze the incidence and epidemic characteristics of local cases infected with SARS-CoV-2 in Yangpu District of Shanghai， China， and provide scientific evidence for the prevention and control of coronavirus disease-19 （COVID-19）. Methods:Descriptive epidemiological methods were applied to analyze the epidemic data of all the patients tested positive for SARS-CoV-2 RNA in Yangpu District of Shanghai， China. Results:A total of 9 local cases （7 males and 2 females） were documented in Yangpu District from January 30， 2020 to February 29， 2020. The average age was （48.56±13.85） years old. According to the body mass index， the patients with overweight and obesity accounted for 44.44% of the total cases. All the patients had fever at the onset and radiological findings of pneumonia by CT examination. They were diagnosed during January 24 and February 8， 2020. The median incubation period of the COVID-19 was 9 days and the median course was 22 days. Six cases had travel history in the epidemic areas and the other 3 cases had history of contact with confirmed cases. There were two familial clusters， both of which were husband-wife relationships. One cluster had a clear temporal sequence of onset， while the other one might be co-exposed or mutually infected. No new local case infected with SARS-CoV-2 was evident since February 8， 2020. Conclusion:All the local COVID-19 cases in Yangpu District have clear epidemiological exposure history. It warrants further attention to the family clustering SARS-CoV-2 transmission. Currently， containment of imported cases is crucial for the prevention and control of COVID-19 epidemic.
ABSTRACT
Objective:To analyze the prevalence trend and survival of liver cancer in Yangpu District， Shanghai， from 2002 to 2016. Methods:Data on liver cancer incidence and mortality from 2002 to 2016 were collected from the Shanghai cancer registry system for the registered population in Yangpu District and the number of the registered population published by the public security department. The standardized liver cancer incidence and mortality rates were calculated using the world standard population to analyze the trends of the liver cancer incidence and mortality， in general， by gender and by age. Life table method was used to calculate the survival rate， and log-rank test was used to analyze the difference of 5-year survival rates and the period of diagnosis between patients with liver cancer by gender. Results:The overall incidence and mortality of liver cancer showed a decreasing trend from 2002 to 2016. After removing the influence of community aging， the standardized annual percentage change （APC） of morbidity and mortality was -3.10% （P<0.01） and -3.44% （P<0.01）， respectively. The morbidity and mortality of males were significantly higher than that of females （P<0.01） by Z test. The incidence of liver cancer started to rise obviously from 40 years old， and the death rate raised obviously from 50 years old. 4 007 liver cancer patients were followed up for 5 years. The 5 years observed survival rate was 12.45%， and the median survival time was 281.48 days. The 5-year survival rate of male liver cancer patients was higher than that of female patients， and there was a significant difference（P<0.01）.46.58% of liver cancer patients were diagnosed in the advanced stage， and only 13.46% was diagnosed at the early-stage. There was no statistical difference in the proportion between men and women at different stages （P=0.11）. Conclusion:The overall incidence and mortality rates of liver cancer from 2002 to 2016 show a slowly decreasing trend， with higher incidence and mortality rates in men than in women. Middle-aged and elderly people are still the main population of morbidity and death. The five-year survival rate is low， and the diagnostic periods are mostly in the middle and late stages of cancer.
ABSTRACT
Objective To study the relationship between central obesity and cardiovascular disease risk factors and aggregation in Yangpu District, and to provide scientific basis for the prevention and control measures and strategies for cardiovascular disease. Methods In the community, residents aged 35 to 75 were investigated by questionnaire, physical examination and blood biochemical test, and a total of 11 321 residents with complete data were analyzed. Results The prevalence of central obesity among adults in Yangpu was 60.50%(standardized rate was 56.09%).The level of systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, triglycerides, low-density lipoprotein and high-density lipoprotein were significantly different in different waist circumference groups(all P < 0.01).With the increase of waist circumference, the prevalence of hypertension, diabetes, dyslipidemia, and cardiovascular risk factors clustering was increased (all P < 0.01).Multivariable logistic regression results showed that the risk of hypertension, diabetes, dyslipidemia and cardiovascular risk factors clustering was 1.78 (OR=1.78, 95%CI:1.63－1.94) and 3.36 (OR=3.36, 95%CI:3.00-3.75);1.67 (OR=1.67, 95%CI:1.49-1.88) and 2.67 (OR=2.67, 95%CI:2.34-3.03);1.68 (OR=1.68, 95%CI:1.54-1.82) and 2.20 (OR=2.20, 95%CI:1.97-2.44);2.05 (OR=2.04, 95%CI:1.86-2.24) and 3.62 times (OR=3.62 95%CI:3.23-4.04) fold higher in residents with mild and severe central obesity than those without central obesity. Conclusion The prevalence of central obesity among residents in Yangpu District of Shanghai is high, and the extent of central obesity is related to cardiovascular diseases risk factors and their aggregation.Therefore, timely intervention measures should be taken to control obesity.

ABSTRACT
A simple, sensitive and reliable method was developed for simultaneous determination of ten banned drugs residues including zeranols(ZALs),chloroamphenicol,pentachlorophenol,etc. in swine urine using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The urine samples were pretreated using lyophilization and QuEChERS procedures, respectively. Acetonitrile and ammonium acetate (5 mmol/L) were chosen as mobile phases. Target compounds were separated well in ZorbaxSB-C18by following the optimized gradient elution program and determined by LC-MS/MS in negative electrospray ionization mode. The linearity of the matrix-matched standard curve of ten analytes in two methods was good in the range of the experimental concentration with correlation coefficients more than 0.99. The recoveries of ten drugs were in the range of 80.7%-107.7% and 73.5%-103.3% at the spiked levels of 5,10 and 20 μg/L by lyophilization and QuEChERS methods,respectively. The coefficients of variation were less than 15%. The limits of detection (LOD) and the limits of quantification (LOQ) from lyophilization and QuEChERS method were 0.1 to 2.0 μg/L and 0.2 to 5.0 μg/L,respectively.
ABSTRACT
Objective To determine the prediction and clinical characteristics of intravenous immunoglobulin (IVIG) treated Kawasaki disease (KD) failure in initial dose.Methods Retrospective analysis was performed with the clinical data of 1 11 children with KD.The paticnts were divided into sensitive group and unresponsive group according to initial effect of IVIG.The clinical manifestations,laboratory examination and radiological features of the children were compared.Logistic regression analysis was performed in significant different indicators to determine independent correlation factors.In order to seek the reference indexes which indicate unresponsive to IVIG,a receiver operating characteristic (ROC) curve was made,of which the diagnostic cut-off was nine independent correlation factors while grouping was made according to patients' different responses to IVIG.Results (1)There were 90 cases (81.1％)in effective group and 21 cases (18.9％) in unresponsive group.(2) Compared with the sensitive group,hyperpyrexia cases[66.7％ (14/ 21 cases) vs 34.4％ (31/90 cases),x2 =7.334,P =0.007] and the chances of coronary artery lesions [47.6％ (10/ 21 cases) vs 23.3％ (21/90 cases),x2 =4.989,P =0.026] were significantly higher in the unresponsive group.(3)Compared with the children administered twice with gamma globulin,the children of single-dose treatment significantly reduced the unresponsive probability [12.5 ％ (9/72 cases) vs 30.8 ％ (12/39 cases),x2 =5.504,P =0.019],and there was no difference in the chances of coronary artery lesions[23.6％ (17/72 cases) vs 30.8％ (12/39 cases),x2 =0.672,P =0.412].(4)Comparing the sensitive group and the unresponsive group,the percentage of neutrophils count [(0.72 ± 0.06) vs (0.76 ± 0.04),t =-2.84,P =0.005],platelet counts [(352.38 ± 42.18) × 109/L vs (373.14 ±36.93) × 109/L,t =-2.076,P =0.040] and C-reactive protein (CRP) [(74.38 ± 12.92) mg/L vs (92.05 ± 11.17) mg/L,t =-5.780,P =0.000] were significantly higher in the unresponsive group,but the level of serum albumin[(34.09 ±3.19) g/L vs (31.61 ±2.03) g/L,t =4.442,P =0.000] was lower.(5) Multivariate Logistic regression analysis indicated that the percentage increase of neutrophils count (P =0.018),CRP (P =0.000) increase and serum albumin(P =0.040) decrease were independent risk factors for unresponsive treatment with gamma globulin.(6)After the area under the ROC curve was calculated,the percentage of neutrophils count,CRP and serum albumin could be effective predictors to IVIG treatment failure in initial dose,and the critical values were 0.72,78.5 mg/L and 33.11 g/L,respectively.Conclusions Treatment with IVIG for the first time may be ineffective in some situations such as the percentage of neutrophils count ≥0.72,CRP ≥78.5 mg/L or serum albumin≤33.11 g/L.
ABSTRACT
Objective ] To analyze the incidence and mortality of liver cancer and survival situation among permanent residents in Yangpu District of Shanghai from January 2002 to December 2012, and compare these data with the statistics obtained from Qidong City of Jiangsu Province. [ Methods] The data on liver cancer among permanent residents in Yangpu District were collected from the database of cancer registration and management system in Shanghai.The temporal trend in the incidence and mortality of liver cancer was assessed and compared with the related statistical data from Qidong City of Jiangsu Province.Kaplan-Meier analysis with log-rank test was performed for survival analysis. [ Results] A total of 3 389 cases of liver cancer were diagnosed from January 2002 to December 2012 . The standardized incidence rate was 15.70/105 in males, significantly higher than 5.45/105 in females ( P<0.05) .A total of 3 026 cases died of liver cancer during this period.The standardized mortality rate was 13.38/105 in males and 4.66/105 in females ( P<0.05).The median survival time was 0.41 years in total, 1.40 years in those who received surgery, significantly higher than 0.35 years in those without surgery ( P <0.05 ) .The ratios between Yangpu District and Qidong City were around 1 ∶3 in both incidence and mortality rates, and about 2 ∶1 in survival rate. [ Conclusion] The mortality of liver cancer close to its incidence among permanent residents in Yangpu District of Shanghai during 2002-2012. Both the incidence and mortality of liver cancer were significantly higher in males than in females.Surgical resection significantly prolongs overall survival time and improves prognosis.Early diagnosis and prompt surgical resection can improve the overall survival rate of liver cancer patients.HBV infection may be the major risk factor of liver cancer in Yangpu District, while liver cancer in Qidong City is likely to be caused by the interaction among many factors including HBV infection, exposure to aflatoxin, genetic factors, drinking water pollution, and lack of microelement.
ABSTRACT
Objective] To explore disaster response capability and the vulnerability as well as the current level and training needs of disaster medicine knowledge in urban populations . [ Methods] Five communities in Yangpu District of Shanghai were randomly enrolled in this study .The study populations were then stratified by age groups .A total of 1700 residents were recruited , 1643 of which completed a structured questionnaire designed by the investigators . [ Results] Eight-nine percent of the residents be-lieved the importance of understanding disaster medicine -related knowledge .The correct answer rates of “pro-tective measures of nuclear leakage issues” and “self-rescue measures in a high building fire” reached over 80%;however , the overall correct answer rate of “cardiorespiratory resuscitation operation” was less than 40%.The main channels of community residents accessing disaster medicine knowledge were mainly news -papers, magazines, and internet (52.1%);whereas only 5.3%of them obtained the knowledge from school education .Community residents most liked to obtain “first aid skills”and“basic theory of disaster medicine”through formal lectures (72.4%). [Conclusion] School education lacks disaster-related knowledge , pos-sibly resulting in the fact that community residents have a limited ability to save both oneself and others in disaster .There are significant differences between residents with different education levels .Community resi-dents have limited knowledge of disaster occurrence and development , and lack capabilities of self-rescue and mutual aid .Colleges should increase the contents of disaster medicine education in their curriculum .Disaster education should be enforced in school education .Continued education and simulation of disaster-related knowledge should be regularly offered to community residents to greatly reduce their vulnerability to disasters .
ABSTRACT
Lateral ventricular meningiomas (LVMs) are especially rare, and they often remain "silent" until they become very large. Several surgical approaches exist, but the optimal surgical strategy for them remains a challenge. The incidence, clinical features, radiological manifestations, pathological findings, and especially the surgical strategy in 21 patients with LVMs were analyzed retrospectively. The mean age of patients was 42.7 years (range, 17 to 78 years). Raised intracranial pressure was the main presenting symptom. The definite diagnosis of LVMs in most cases was made by computed tomography (CT) or magnetic resonance imaging (MRI). Six patients were subjected to plain CT scans, 15 to contrast MR scans, and 4 to a magnetic resonance angiogram (MRA). Large tumors were seen in most cases with an average diameter of more than 4.3 cm. Of the 21 cases of LVMs in our series, LVMs were resected in 16 cases via a posterior parieto-occipital transcortical approach, 2 cases via a transcallosal approach, and 3 cases via a posterior middle temporal gyrus approach. In 8 out of 21 cases, the tumors were located in the left lateral ventricle. The gross total surgical excision was achieved in 18 (86%) patients, and all LVMs were pathologically confirmed to be benign. Nine patients were followed up (range: 11 months-4.6 years). Eight (88.9%) cases obtained good recovery and one (11.1%) obtained moderate disability. Four approaches are available for the surgical treatment of LVMs. The choice of surgical approaches depends on tumor location, laterality, size and extension, and the function of the brain must be taken into account. Intracapsular resection and piecemeal resection of LVMs can be safely and easily performed. Preoperative MRA scan is important to know the feeder of LVMs and peripheral blood supply.

ABSTRACT
<p><b>OBJECTIVE</b>To analyze the incidence and survival rates of primary liver cancer (PLC) among residents in Yangpu district of Shanghai.</p><p><b>METHODS</b>A total of 9 730 736 permanent residents (male 4 996 390 and female 4 734 346) of Yangpu district in Shanghai were recruited in the study between year 2002 and 2010; among whom 2726 PLC cases were diagnosed and 2427 death cases were certified. The incidence and mortality of PLC were calculated under the analysis of the new PLC cases and death cases between year 2002 and 2010. The rates were standardized by the demographic composition developed in the Fifth Nationwide Census in year 2000, in order to analyze the survival condition of PLC patients and explore the prognosis of surgical excision treatment.</p><p><b>RESULTS</b>Among the new PLC cases between year 2002 and 2010, 1966 cases were male, whose average age of onset was 59.81; while 760 cases were female, whose average age of onset was 68.93. The crude incidence rate was 39.35/100 000 in male, which was higher than it in female, as 16.05/100 000. The difference showed statistical significance (U = 7.32, P < 0.01). The standardized incidence rates were 21.98/100 000 and 6.96/100 000 in male and female, respectively. The difference showed statistical significance (U = 221.76, P < 0.01). There were 2427 PLC death cases in total, including 1734 male death cases and 693 female death cases. The crude mortality rate was 34.71/100 000 in male and 14.64/100 000 in female, whose difference were statistically significant (U = 6.68, P < 0.01). The standardized mortality rate was 19.16/100 000 in male and 6.06/100 000 in female, whose difference were statistically significant (U = 207.18, P < 0.01). The incidence and mortality rates both increased apparently since males aging over 35 and females over 45. The 1 - 5 year survival rates of PLC patients were 33.95%, 23.11%, 17.04%, 14.42% and 12.29%, respectively. In the surgical excision treatment group (321 cases), the 1 - 5 year survival rates were separately 66.78%, 52.87%, 41.88%, 33.57% and 32.64%; while in the non-surgical treatment group (2405 cases), the 1 - 5 year survival rates were separately 29.04%, 18.58%, 13.30%, 11.16% and 9.01%. The differences in 1 - 5 year survival rates between surgical and non-surgical groups all showed statistical significance (U = 12.78, 10.52, 8.28, 5.56 and 5.12, respectively, P < 0.01).</p><p><b>CONCLUSION</b>The incidence of PLC was close to its mortality in Yangpu district of Shanghai. The male incidence and mortality rates were significantly higher than female corresponding rates. The surgical excision treatment could improve the prognosis of PLC.</p>

Both the incidence and mortality rates increased apparently in those older than 45 years. The 1- to 5-year survival rates in all cases were 37.42%, 22.71%, 15.73%, 12.32%, and 10.53%, respectively. The 1- to 5-year survival rates in male cases were significantly lower than those in female cases (P < 0.05 for each comparison). The 1- to 5-year survival rates of the patients whose tumor had been surgically removed were significantly higher than those in the patients without surgery (P < 0.05 for each comparison).</p><p><b>CONCLUSIONS</b>The incidence of lung cancer is close to the mortality in the residents of Yangpu District of Shanghai city. Surgical resection treatment improves the prognosis of lung cancer.</p>

Objective To know the epidemiological characteristics of hand-foot-mouth disease in Yangpu District and provide evidence for specific strategies and measures of hand-foot-mouth disease activity prevention and control. Methods Descriptive analysis of the data from hand-foot-mouth disease epidemic situation in Yangpu District from 2005 to 2008 was made. Results 1 348 cases were reported in the whole Yangpu District from 2005 to 2008, and no severe cases, no death. The average morbidity in Yangpu District was 27.48/100 000. The male to female ratio was 1.46∶1. The infection occurred to infants aged from 1 year to 5 years (85.39%). The incidence of the native population children aged 2 to 3 exceeded 10/100 000. The season peak appeared from May to July (70.18%), and outbreaks used to occur at nurseries and kindergartens. The typical clinical presentations mainly included fever and rash. The rash mainly occurred to hands, feet, mouth, buttocks and so on. Conclusions Incidence varied significantly between different sexes, seasons and ages. It can cause large-scale epidemic in a short period of time, the epidemic was very difficult to control, but the leaders attach importance to take the early warning and monitoring, accuratey deal with emergencies, health education promotion and training of comprehensive measures, the epidemic can be effectively controlled.
ABSTRACT
Objective To establish and evaluate a gene microarray for determination katG mutations of Mycobacterium tuberculosis isolates associated with resistance to isoniazid(INH).Methods A panel of probes were designed and gene chips were prepared by dotting.Mycobacterium tuberculosis isolates resistance to 5 drugs was determined by proportional dilution methods.Amplicons of Mycobacterium tuberculosis isolates were detected by our chip and sequenced.Results The drug resistance rate of the isolates to at least one of the anti-tuberculosis drugs was 70.8%(97/137).45 strains out 137 Mycobacterium tuberculosis isolates was resistant to INH(32.8%).katG was successfully amplified from 100% of the susceptible strains and 88.9%(40/45)resistant strains.4 of 45 INH resistant isolates' katG were deleted.27 of 40(67.5%) katG has been detected to have katG 315 codon mutations.The mutations were 315 AAC(Asn,13/40), ACC(Thr,6/40),ACA(Thr,4/40),ATC(Ile,2/40),AGC(Arg,2/40).The mutation rate of katG analyzed by gene chips we prepared were identical to katG sequencing.Conclusion The gene microarray techniques we developed for determination of Mycobacterium tuberculosis resistance to INH are specific, sensitive and may be used as an alternative in clinical laboratory.
