Objective To systematically evaluate the economic burden of echinococcosis patients in western China using meta-analysis, so as to provide insights into formulation of effective echinococcosis control strategies and optimization of medical resource allocation. Methods Articles pertaining to the economic burden of echinococcosis patients in western China were retrieved in international and Chinese databases, including PubMed, Web of Science, CNKI, Wanfang Data, and VIP Chinese Science and Technology Periodicals Full-Text Database. Studies were screened according to inclusion and exclusion criteria, and the basic characteristics of included articles, characteristics of included studies, and echinococcosis patients’ economic burden were extracted. A meta-analysis was performed using the software R package. The pooled effect size and heterogeneity were examined using a random effects model, and subgroup analyses were conducted. Results A total of 13 articles were enrolled, including 12 Chinese publications and one English publication, and all were retrospective studies. Included studies covered 4 western provinces (autonomous regions) of China, including Ningxia Hui Autonomous Region, Xinjiang Uygur Autonomous Region, Sichuan Province, and Qinghai Province, which involved 11 282 echinococcosis patients, and the study period spanned from 2006 to 2023. Meta-analysis showed that the pooled direct medical costs of echinococcosis patients were 24 730 [95% confidence interval (CI): (13 040, 36 430)] Yuan in endemic areas of western China, appearing a significant heterogeneity (I² = 79.95%, P < 0.01). Subgroup analyses showed the pooled direct medical costs of 9 090 [95% CI: (-4 970, 23 150)] Yuan for echinococcosis patients in Ningxia Hui Autonomous Region and 18 140 [95% CI: (8 440, 27 840)] Yuan in Xinjiang Uygur Autonomous Region, and pooled direct medical costs of 9 470 [95% CI: (-1 850, 20 790)] Yuan for cystic echinococcosis patients prior to 2007 and 15 270 [95% CI: (560, 24 030)] Yuan after 2007, respectively. There were high heterogeneities in the pooled direct medical costs for echinococcosis patients in terms of date of publication (I² = 82.05%, P < 0.001), treatment modality (I² = 83.28%, P < 0.001) and type of echinococcosis (I² = 72.63%, P < 0.001). In addition, the pooled indirect medical costs and direct non-medical costs were 5 670 Yuan and 4 000 Yuan for echinococcosis patients in western regions of China, respectively. Conclusions Echinococcosis patients suffer from a high economic burden in endemic areas of western China, and there are disparities in the direct medical costs for echinococcosis patients depending on disease type, study areas and study period.

Objective To analyze the echinococcosis surveillance results in Bayingolin Mongol Autonomous Prefecture, Xinjiang Uygur Autonomous Region from 2017 to 2022, so as to provide insights into formulation of echinococcosis control measures in the prefecture. Methods Villagers were randomly sampled using a multistage sampling method from class I and II echinococcosis endemic counties in Bayingolin Mongolian Autonomous Prefecture from 2017 to 2022 for detection of human echinococcosis, while all patients undergoing ultrasound examinations in medical institutions in class III endemic counties received active echinococcosis screening. In addition, livestock in centralized slaughterhouses or slaughtering sites were screened for echinococcosis using the palpation and necropsy method, and fresh domestic dog feces samples were collected from randomly selected dog owners in each administrative village for detection of Echinococcus copro-antigen in domestic dogs. The trends in detection of human and livestock echinococcosis, detection of newly diagnosed human echinococcosis cases and detection of Echinococcus coproantigen in domestic dogs were analyzed in Bayingolin Mongol Autonomous Prefecture from 2017 to 2022. Results The mean detection rate of human echinococcosis was 0.13% (540/407 803) in Bayingolin Mongol Autonomous Prefecture from 2017 to 2022, which appeared a tendency towards a decline over years (χ²_trend = 1 217.21, P < 0.001), and the highest detection of newly diagnosed echinococcosis cases was seen in Hejing County (0.28%, 191/67 865). The detection of livestock echinococcosis appeared a tendency towards a decline over years from 2017 to 2022 (χ²_trend = 147.02, P < 0.001), with the highest detection rate seen in Hejing County (3.44%, 86/2 500), and the detection of Echinococcus copro-antigen in domestic dogs appeared a tendency towards a decline over years from 2017 to 2022 (χ²_trend = 302.46, P < 0.001), with the highest detection rate in Qiemo County (2.74%, 118/4 313). Conclusions The detection of human and livestock echinococcosis and dog feces antigens Echinococcus copro-antigen in domestic dogs all appeared a tendency towards a decline in Bayingolin Mongol Autonomous Prefecture, Xinjiang Uygur Autonomous Region from 2017 to 2022; however, there is still a high echinococcosis transmission risk in local areas. Sustainable integrated echinococcosis control is required in Bayingolin Mongol Autonomous Prefecture.

Objective To perform an epidemiological investigation on a case of visceral leishmaniasis reported from Shule County, Kashi Prefecture, Xinjiang Uygur Autonomous Region in 2021, so as to provide insights into differential diagnosis of visceral leishmaniasis during the COVID-19 pandemic. Methods The epidemiological history of this case was collected, and the case was diagnosed for Leishmania infection with the immunochromatographic (rK39) strip test, bone marrow smear microscopy and PCR assay. Results The patient had typical clinical symptoms of leishmaniasis, including irregular fever, hepatosplenomeg- aly, low serum albumin and elevated globulin. Bone marrow smear microscopy identified L. donovani amastigotes, and both rK39 strip test and PCR assay were positive, while the case was tested negative for SARS-CoV-2. COVID-19 was therefore excluded and visceral leishmaniasis was diagnosed. Standard full-dose treatment with sodium stibogluconate was given, and no Leishmania was found on blood smears during the reexamination. No recurrence was found during the followup after discharge for hospital. Conclusions During the COVID-19 pandemic, it is recommended to increase the perception of differential diagnosis of visceral leishmaniasis among first-contact doctors, and reinforce the capability of differential diagnosis and health education of visceral leishmaniasis among medical and healthcare institutions at all levels, to prevent missed diagnosis and misdiagnosis of visceral leishmaniasis.

A series of isoindoline derivatives were designed, synthesized, and evaluated for their double inhibitory activities. All of them were new compounds, and their structures were confirmed by 1H NMR and HR-MS. Preliminary in vitro pharmacological tests showed that all compounds exhibited 5-HT or NE reuptake inhibition activity. Among the tested compounds, compound I-3 exhibited potent inhibitory activity against 5-HT and NE reuptake in vitro, and exhibited potent antidepressant activity in vivo. These compounds designed can be further optimized for finding more potent 5-HT/NE dual reuptake inhibitors and antidepressant candidates as well.

OBJECTIVETo understand the Escherichia coli O157:H7 carrier rate of host animals and the toxic gene of the strains in different areas in Jiangsu province.

METHODSSurveillance spots were set up in different areas, to collect feces of pigs, chickens, sheep, cattle to culture for O157:H7 with immunomagnetic separation as well as detection of toxic gene of the strain with MPCR were both carried out.

RESULTSOne hundred and seventy strains of O157:H7 were separated from 1 767 feces of different animals in six spots, with a overall positive rate 9.62%. The positive rates of cattle and sheep were 19.05% and 12.01% respectively. Among 85 strains SLT1, SLT2, eaeA and hly toxic genes were detected. In which, 56.47% of the strains were positive curturely while 79.17% of them carried SLT2, eaeA and hly gene simultaneously.

CONCLUSIONThe positive rate of O157:H7 in animals and the positive rates of strains were correlated to the incidence of the area. The highest rates were seen in areas where there had been O157:H7 epidemic, followed by the areas where there were only scattered cases identified while the lowest was in areas with no patients. Data indicated that it was important to enforce the surveillance of O157:H7 in animals to better predict and control of the disease.
