ObjectiveTo investigate and manage an imported dengue fever (DF) outbreak in Shanghai in 2024, to summarize the experience and lessons learned from the on-site management, and to provide a reference basis for future prevention and control of DF. MethodsEpidemiological investigation and case search were carried out for an imported DF outbreak in Shanghai, 2024. Real-time fluorescence polymerase chain reaction (RT-PCR) was used to detect dengue virus nucleic acid in the serum samples from cases. Meanwhile, emergency vector surveillance and mosquito control measures were carried out in the affected areas, and the effectiveness of the management was evaluated. ResultsAccording to the epidemiological investigation, it was confirmed that this epidemic was a family cluster of imported DF, with both cases infected in Thailand and developed symptoms successively after returning to Shanghai. Laboratory testing identified the pathogens as dengue virus serotype-3 (DENV-3). In the core and precautionary area, ultra-low-volume space spraying and residual spraying were combined to kill adult mosquitoes, and at the same time, comprehensive cleaning and elimination of mosquito breeding sites was carried out. After 2 weeks, the Breteau Index (BI) in the core area decreased from 20 to 5, and the mosquito net trap index decreased from 2 mosquitoes (net·hour)^-1 to 0.67 mosquitoes (net·hour)^-1. Continuous implementation of mosquito control measures kept the BI and net trap index below the safety thresholds [BI<5 and mosquito net trap index <2 mosquitoes (net·hour)^-1] both in the core and precautionary area. ConclusionEarly diagnosis and isolation of patients, combined with rapid suppression of the density of vector Aedes mosquitoes, are the key measures to prevent the transmission of imported DF cases.

Objective To report the endoscopic and hispathology characteristics of the intestinal schistosomiasis, and arose enough attention to avoid missed or misdiagnosis. Methods Clinical and endoscopic and hispathology data of the intestinal schistosomiasis in 72 patients were included in this study with Olympus CF-240 colonoscopy and biopsy.Results Endoscopic appearance showed acute enteritis in 16 cases, chronic enteritis in 27 cases and a mixed type of acute and chronic enteritis in 29 cases. In acute enteritis ova were deposited intactly with lots of eosinocyte infiltration, in chronic enteritis ova were calcified and deposited with lots of lymphocytes,plasma cells infiltration and submucosal fibrosis,while in the mixed type enteritis had both acute and chronic histopathologic appearence. Five of 72 cases were found colorectal cancer simultaneously. And 14 of 72 patients had misdiagnostic history,including ulcerative colitis 7 cases, ileocecum cancer 5 cases, and colonrectal tuberculosis 2 cases.Conclusion Intestinal schistosomiasis is classified into three types of enteritis acute,chronic and the mixed type, the latter was an important and indepent type.Colonscopy findings and repeated biopsy from the suspected lesions were essential for getting correct diagnosis.

OBJECTIVE:To probe into the factors restricting the informationization construction of the medical logistics and to facilitate the informationization construction in China.METHODS:The restricting factors for the logistics'informationization construction and the causes were discussed starting from the trade characteristics of medical logistics by literature reviewing and observation.RESULTS & CONCLUSIONS:The imperfect trade system,the lack of interdisciplinary talents, and the lagged IT technology were the factors restricting the informationization construction of the medical logistics.However, the impacts of these restricting factors can be reduced by developing the third party special pharmaceutical logistics which is helpful for medical logistics'informationization construction.

Objective To elucidate the pathogenesis of nodular duodenitis by investigating its endoscopic and histopathological characteristics. Methods One hundred and thirty-six patients were enrolled into study. Histopathological changes of duodenal tissue specimens were examined by H-E and AB/PAS staining. H.pylori was demonstrated by Giemsa staining and rapid urease test. Results Under endoscopy, all 136 patients with nodular duodenitis had nodular lesions (ranged from 0.2 cm to 1.0 cm), variant degrees of erythema and edema, among them 21 cases had erosion, and 30 cases had haemorrhagic spots and/or ecchymoses. The detecting rate of nodular duodenitis was 0.9%(136/15 820) of all the endoscopic examinations and 3.8%(136/3541) of duodenitis. There was 107 cases of nodular duodenitis identified by histopathological examination including 53 cases of chronic duodenitis and 54 cases of active duodenitis. The histopathological characteristics of chronic duodenitis were lymphocytes and plasmocytes infiltration and varied degrees of atrophic duodenal villi and glands. While in active duodenitis, there was neutrophilic granulocytes infiltration. There were 51 cases of Brunner's gland hyperplasia and 59 cases of gastric epithelial metaplasia. Among all patients, 7 cases were proved to be gastric heterotopia, 4 cases of schistosomiasis and 18 cases of normal tissue. Among 107 nodular duodenitis, the positive rate of H.pylori infection was 45.8% (49/107), the infection rate of H.pylori in active duodenitis(59.3%,32/54) was significantly higher than that in chronic duodenitis (32.1%,17/53) (P

Objective:To explore the influencing factors on outpatients′ satisfaction of medical service.Methods: 195 samples coming from 5 provinces: Shandong,Hebei,Liaoning,Heilongjiang and Jilin province,and Tianjin City were all from the outpatients′ pupulation within a year,and were investigated with questionnaires.The data were collected by face-to-face survey,and totally 134 valid questionnaires were gathered.We use the following methods to complete data analysis: independent sample t-test,and analysis of variance,analysis of correlation,expecting to find the personal factors to affect outpatient satisfaction.Results: research outcome indicates that gender has no effect on outpatient′s satisfaction;while indexes as age and education level have significant influence.

Objective:To help hospitals at different levels develop and provide patients with high-quality medical services.Methods: Primary data were gathered through face-to-face surveys with questionnaires employed.Totally 195 questionnaires and 134 valid questionnaires were collected.Analysis of variance,independent-sample test,and cross-table combining z-test were used to complete data analysis.Results: Research outcome indicates there is no significant difference in outpatients' satisfaction level among hospitals at different levels,similar to outpatients' loyalty level.There are different affecting factors on outpatients' recommendation and satisfaction.Conclusion: Hospitals should be clear of patients' satisfaction level,evaluate patients' loyalty objectively,and make great effort on patients' concerning aspects.
