ABSTRACT
Objective@#To analyze the spatio-temporal distribution characteristics of new HIV/AIDS cases at ages of 50 years and older in Wenzhou City from 2006 to 2020, so as to provide insights into precise control of AIDS. @*Methods @#The data of new HIV/AIDS cases aged 50 years and older in Wenzhou City from 2006 to 2020 were collected from the China Information System for Disease Control and Prevention. The temporal and spatial distribution characteristics of new HIV/AIDS cases at ages of 50 years and older were identified using global and local spatial autocorrelation analyses and spatial-temporal scan analysis.@*Results@#Totally 1 917 new HIV/AIDS cases aged 50 years and older were detected in Wenzhou City from 2006 to 2020, and there were 179 new HIV/AIDS cases in 58 townships ( streets ) from 2006 to 2010, 643 cases in 113 townships ( streets ) from 2011 to 2015 and 1 095 cases in 147 townships ( streets ) from 2016 to 2020, respectively. The distribution of new HIV/AIDS cases appeared positive spatial autocorrelations from 2006 to 2010 ( Moran's I value=0.05, Z=1.976, P=0.046 ), from 2011 to 2015 ( Moran's I value=0.08, Z=2.314, P=0.028) and from 2016 to 2020 (Moran's I value=0.18, Z=3.956, P=0.003 ). Spatial-temporal scan analysis identified two clusters. The primary cluster mainly covered 70 towns ( streets ) in Lucheng Distrct, Ouhai District, Longwan District, Economic and Technical Development Region, Rui' an City and Pingyang County of Wenzhou City from January 1, 2014 to December 31, 2020, with a cluster radius of 34.30 km [log likelihood ratio ( LLR )=192.84, RR=2.60, P<0.001], and the secondary cluster was located in Hongqiao Township of Yueqing City from January 1, 2009 to December 31, 2015, with a cluster radius of 0 ( LLR=90.60, RR=7.27, P<0.001 ).@*Conclusions@#The number of new HIV/AIDS cases aged 50 years and older appeared a tendency towards a rise in Wenzhou City from 2006 to 2020, with spatial clusters that were predominantly identified in urban areas, Rui' an City and Pingyang County of Wenzhou City.
ABSTRACT
Objective Arenavirus is a negative single-stranded RNA virus and an important human pathogen,mainly harbored and transmitted by rodents,causing severe diseases,including hemorrhagic fever and encephalitis.Following the discovery of a novel pathogenic arenavirus (Wenzhou virus,WENV),the prevalence of WENV in local small rodents was investigated.Methods By using RT-PCR,WENV was screened in 48 and 156 rodents sampled from Wenzhou and Longquan,respectively.Results Consequently,WENV was detected in 5 (10.41％) rodents sampled from Wenzhou.However,no WENV was identified in all the rodents sampled from Longquan.Genetic analysis of complete genome sequences indicated that 4 of 5 virus strains were closely related to the known Wenzhou viruses with high homology.Especially,the L and S segments of Wencheng-Rn-288 strain shared homology of 87.5％ and 91.6％ with other viruses,respectively.They formed a distinct lineage,suggesting that this strain might be a novel variant of WENV.Conclusions Our results indicate that WENV has a high prevalence and high genetic diversity among rodents in Wenzhou.As the respiratory disease caused by WENV has been detected in Cambodia,it is necessary to strengthen the surveillance for WENV in China.
ABSTRACT
Objective To analyze the characteristics of malaria prevalence in Wenzhou City,so as to provide the evidence for improving the comprehensive control of malaria. Methods The epidemiological data of malaria cases in Wenzhou City in 2015 were collected and analyzed with the descriptive epidemiological methods. Results Totally 24 imported malaria cases were reported in Wenzhou City in 2015 with the incidence of 0.26 per 100000 and no case was dead. Plasmodium vivax,P. fal-ciparum,and P. ovale were identified in 1(4.17%),20(83.33%),and 3(12.50%)cases,respectively. The cases reported in Rui'an,Cangnan and Lucheng counties/districts accounted for 70.83%(17/24)of the total cases in Wenzhou City. The cases were mostly concentrated in male young adults and 23 cases(95.83%)were imported from Africa. Conclusion Malaria epi-demic situation in Wenzhou City is relatively stable and no local malaria cases were reported in 2015. However,the control work of imported malaria should be strengthened.
ABSTRACT
Objective To analyze and compare the capacity and efficiency of county-level hospitals′medical service by using the diagnosis related groups ( DRGs ) method. Methods The homepage data of discharged inpatients from seven county-level hospitals in Wenzhou region in 2013 - 2015 period were analyzed, for measurement of the medical service capacity changes of such hospitals using the number of DRGs, total multiplicity of weight, and CMI value, and that of their medical service efficiency changes using expense consumption index and time consumption index. Results The study found in the seven hospitals 8. 49% increase of the total number of DRGs, 17. 34% increase of total multiplicity of weight, and 5. 06%increase of CMI value, with unchanged expense consumption index and 9. 82% decrease of the time consumption index. These facts evidenced enhancements of these hospitals in both service capacity and service efficiency in general. Conclusions DRGs as tools prove useful objectively and scientifically. Policies of Two emphases at primary ends and two enhancements have been implemented desirably.
ABSTRACT
The three death cases of falciparum malaria in Wenzhou City were all imported from Africa. One patient died on 10 January 2007 because of severe clinical symptoms after hospitalization. The second case was initially misdiagnosed as influen-za in primary health and medical institution. The patient's condition quickly worsened and died of Plasmodium falciparum infec-tion on 5 March 2011. The third patient belonged to"non-identity"person,and there were no detailed information and epidemio-logical history on admission,which resulted in the delayed diagnosis,disease exacerbation and death. In conclusion,the health education should be provided to the people who return from Africa and also to medical workers in order to reduce the mortality of falciparum malaria.
ABSTRACT
Objective To investigate a poisoning caused by wild mushrooms and to identify the toxin in these mushrooms.Methods Epidemiological investigation,blood test and mushroom toxin were analyzed.Results This incident was taken place in one family,and all family members were dead.Multiple organ damage was observed in all patients;amatoxins and virotoxins were detected in both mushrooms and the soup,but were not detected in blood samples because of dialysis.Conclusion The incident was caused by wild mushrooms and public education shoud be strenthened to urge people to avoid eating wild mushrooms and go to the hospital immediately if poisoning takes place.
ABSTRACT
Objective To analysis the human T lymphotropic virus (HTLV) infection status in Wenzhou among voluntaty blood donors.Methods Selected 72 417 voluntary blood donors of Wenzhou from from March,1,2016,to November,30,2016,to screen HTLV-Ⅰ / Ⅱ antibody by ELISA method.The positive samples were reexamined two times,two test results of samples were determined positive by ELISA.HTLV positive samples was confiemed by Western Blotting (WB).Results Screened 23 cases of anti-HTLV positive by ELISA method,then confirmed 9 cases of HTLV positive by Western Blotting (WB).HTLV infection rate of Wenzhou blood donors was 0.01％ (9/72 417).Conclusions HTLV infection was found among volunteer blood donors in Wenzhou,but the HTLV infection rate of volunteer blood donors in Wenzhou is still at a relatively low level.

ABSTRACT
Based on the ongoing health reform and Wenzhou's economic and social developments,this article made a complete analysis on the policy packages initiated by Wenzhou government in August 2012,in an effort to encourage and involve private capital to launch medical institutions.These policies and measures released take into account the policy and legal environment for private capital in medical sector in China,and target the demands of deepening health reform and shortage of health development funding.Such efforts of Wenzhou are designed as breakthroughs in terms of market access,doctors mobility,return on investment,health insurance and fiscal policy.
ABSTRACT
Objective To determine the effect of fast passage for patients' access to the emergency department of hospital on rescuing and triaging the traumatic casualties referred from the site of accident by collision between two bullet trains occurred at Wenzhou station on 23 July 2011 in order to accumulate experience of treating large number of traumatized casualties happened in a major accident or disaster.Methods A retrospective study was carried out to collect the data including the different courses of treatment for various types of injury in casualties and the length of stay of traumatized patients with different degrees of severity in the emergency department after casualties entered into the emergency department of hospital via fast passage.Results There were 136 traumatic casualties referred to hospital within 72 hours after the bullet train accident occurred at Wenzhou station.The average length of stay of patients with uncomplicated single injury in the hospital was 27min,and the average length of stay of 108 patients with multiple injuries in the emergency department was 62 min.In last year,the annually average length of stay of casualties in emergency department was 50 min longer when there was no fast passage available for patient to enter into.Conclusions The fast passage for casualties entering into emergency department not only guarantees the traumatized patients rescued in no time after bullet train accident but also shortens the length of stay in the Emergency Department.
ABSTRACT
Objective To investigate the current status and changing patterns of hemodialysis in Wenzhou areas of China from 1999 to 2006. Methods Data of blood purification centres of 18 hospitals in Wenzhou areas from 1999 to 2006 were collected. The incidence, prevalence, mortality, the etiology and the relevant factors such as age, gender, dialysis ages, outcomes and causes of death in end stage renal disease(ESRD) patients on hemodialysis(HD) were analyzed retrospectively. Results The incident number and the number of patients increased annually while the mortality remained steady. The male patients outnumbered the female every year, but the male/female ratio was decreasing. The percentage of both young and oldly patients was increasing. The first cause was chronic glomerulonephritis, although the constituent ratio of glomerulonephritis decreased year by year. The constituent ratio of diabetic nephropathy and hypertensive nephropathy increased. The constituent ratio of dialysis age 1-2 years group decreased, ≤1 year, 2-3 years, 3-4 years groups were relatively steady, and 4-5 years, 5-10 years, 10 years groups increased. The number of patients receiving renal transplantation and transferring to peritoneal dialysis increased annually. The leading cause of death was cardiovascular incidence (19.9%), followed by cerebrovascular disorder (10.8%), systemic failure (10.8%), hemorrhagic diseases(4.7%) and infectious diseases(4.3%). The constituent ratio of cardiovascular incidence and cerebrovascular disorder were relatively steady. The constituent ratio of hemorrhagic diseases and systemic failure showed great fluctuation. The constituent ratio of infectious diseases and malnutrition was decreasing. Conclusions In Wenzhou area from 1999 to 2006, the patients number has been increasing annually. The onset age of HD is 30-70 years old, and proves a younger tendency and older tendency. The leading cause is chronic glomeralonephritis. The constituent ratio of diabetic nephropathy and hypertensive nephropathy rises year by year. The long-term survival rate of HD patients is improved. The leading cause of death is cardiovascular accident.
ABSTRACT
95%).Strains of PNSP were significantly more common than those PSSP(72.56% vs 22.72%),and strains of Sp resistant to erythromycin were significantly more common than susceptible to erythromycin too(94.42% vs 0.88%).Conclusions The antimicrobial resistance of Sp from children with lower respiratory tract infection in Wenzhou area has became a severe problem.Multi-drug resistance of Sp has been observed to chlorodeoxylincomycin,erythromycin,tetracycline and so on.The results will provide some important information for the therapy and the choice of antibiotics of Sp infection.
