Objective:To investigate the infection of spotted fever group Rickettsiae (SFGR) and Rickettsia mooseri ( R.mooseri) of wild rodents in the field of plague foci in Western Yunnan. Methods:The DNA of liver samples of 2 512 wild rodents captured from the plague foci in Lianghe County, Jianchuan County and Yulong County in Western Yunnan from 2015 to 2016 was extracted by magnetic bead method, and the heat shock protein groEL gene primers were used for nested PCR amplification. Gene sequence splicing and Blast homology comparison were performed using DNAStar 7.1 software and GenBank of the National Center for Biotechnology Information (NCBI) of the United States, respectively, and DNAStar 7.1 and MEGA 6.0 softwares were used to construct phylogenetic trees.Results:The wild rodents infected with SFGR were Mus pahari, Rattus steini, Crocidura attenuata and Suncus murinus (one for each), with a total infection rate of 0.16% (4/2 512); no R.mooseri infection was detected. The SFGR infection rates of wild rodents in the plague foci of Lianghe County and Jianchuan County were 0.49% (3/611) and 0.10% (1/1 029), respectively; no SFGR infection was detected in the wild rodents in the plague foci of Yulong County. The homology analysis showed that the homology between SFGR positive samples and reference sequences was 95.45%-100.00%; some of the groEL gene sequences were highly similar among the four positive samples, and the homology was 89.60%-97.40%. Sequence evolution analysis showed that the sequences of three SFGR positive samples from the plague focus in Lianghe County were clustered in the same branch, and the homology reached 94.40%-97.40%; one positive sample sequence from the plague focus in Jianchuan County was clustered in one branch. Conclusion:SFGR infection rate of wild rodents in the field of plague foci in Western Yunnan is low, and no R.mooseri infection is found.

Objective:To analyze the epidemiological and clinical characteristics of human brucellosis in Sichuan Province, and to provide a scientific basis for prevention and control of brucellosis.Methods:Retrospective analysis methods were used to collect the data of reported cases of brucellosis in Sichuan Province from 2018 to 2020 from the "Infectious Disease Reporting Information Management System" in the "China Disease Prevention and Control Information System". The distribution (population, time and region) and case investigation data (epidemiological contact history and clinical manifestations) were analyzed by descriptive epidemiological.Results:A total of 309 cases of brucellosis were reported in Sichuan Province in 2018 - 2020, and no deaths occurred. The annual incidence rate was 0.123/100 000. Among the 309 reported cases of brucellosis, the sex ratio of men to women was 2.4 ∶ 1.0 (218 ∶ 91); the age of onset was mainly 20 - 60 years old, accounting for 79.9% (247/309); the occupation was mainly farmers, accounting for 51.8% (160/309). Brucellosis cases were reported in every month of the year, mainly from March to August, accounting for 72.5% (224/309) of the total number of cases. Cases were reported in 21 cities (autonomous prefectures) in Sichuan Province from 2018 to 2020. The top 5 cities (autonomous prefectures) in terms of cumulative number of cases were Chengdu, Liangshan, Zigong, Neijiang and Luzhou in order, accounting for 60.5% (187/309) of the total number of cases. Among the 309 reported cases of brucellosis, 279 case investigations were completed. Among them, 258 cases had a history of contact with livestock and their products, accounting for 92.5%; all contacted livestock were sheep; the main mode of transmission was direct contact, accounting for 88.5% (247/279); the main routes of transmission were sheep farming (50.2%, 140/279), sheep slaughtering (18.6%, 52/279), selling mutton or cutting sheep products in mutton restaurants (11.1%, 31/279); the main clinical manifestations were fever, fatigue, hyperhidrosis, and muscle and joint pain, accounting for 91.4% (255/279), 89.2% (249/279), 80.3% (224/279) and 65.2% (182/279), respectively.Conclusions:The spread of brucellosis in Sichuan Province is increasing, and spring and summer are the epidemic seasons. Brucellosis cases are most common in sheep farms, and the infection method is mainly direct contact infection; the clinical manifestations are diverse and non-specific. Relevant departments should strengthen the prevention and control of the disease in key populations and regions to control the outbreak of brucellosis.

Objective:To learn about the infection and gene polymorphisms of hepatitis E virus (HEV) in murine-shaped animals of plague foci in Yunnan Province.Methods:From July to August 2019, around 16 natural villages (4 in Mile City, 6 in Mangshi and 6 in Lianghe County), which were the foci of domestic plague in Yunnan Province, the murine-shaped animals were captured by the night-time method. The liver RNA was extracted, and the target gene of rat HEV was detected by one-step real-time fluorescence quantitative PCR, and the positive rate of rat HEV was calculated. The rat HEV positive samples were amplified by PCR for further clone sequencing, and the resulting sequences were compared with the HEV sequences registered in the GenBank and a phylogenetic tree was constructed by using MegAlign and MEGA 7.0.Results:A total of 491 murine-shaped animals were captured from 3 orders, 5 families, 8 genera, 15 species, and the positive rate of rat HEV was 4.89% (24/491). Among them, the positive rate of Rattus tanezumi and Niviventer fulvescens was 9.39% (23/245) and 1/3, respectively; and other species were negative. There was a statistically significant difference in the positive rate of rat HEV between different habitats ( P = 0.014), and the positive rate of rat HEV in the habitats near the dwellings was higher than that in other habitats ( P < 0.05). The sequence comparison analysis showed that the gene sequence of P018 from Lianghe County was 100.0% homologous to the MG813927.1 sequence of the first patient with rat HEV in Hongkong, and it was clustered into the same branch with the sequences of MG813927.1 and LC549185.1 from rat, was the type HEV C. G024 from Mangshi shared a low homology (20.7% - 31.5%) with other virus strains, and it was clustered into the same branch with a HEV sequence from an avian (AY535004.1). Conclusions:Rat HEV is prevalent in murine-shaped animals of plague foci of Yunnan Province, and there may be gene polymorphisms of rat HEV. In addition, the difference infection rate may be related to the habitats.

Objective:To detect and analyze the contents of eight metal elements in water samples of plague foci in Yunnan Province.Methods:During the period from December 2015 to November 2016, the plague foci of Yulong, Jianchuan and Lianghe were selected as sampling sites, water samples were collected in areas with rodent activities in the 4 seasons of spring, summer, autumn and winter. The contents of eight metal elements calcium (Ca), iron (Fe), zinc (Zn), chromium (Cr), plumbum (Pb), manganese (Mn), cadmium (Cd) and cuprum (Cu) in water samples were measured by flame atomic absorption spectrometry (FAAS), and the data [median (interquartile distance)] were statistically analyzed.Results:Twenty-six, 58 and 54 water samples were collected from Yulong, Jianchuan and Lianghe plague foci, respectively. The contents of metal elements of Pb and Cd in water samples of the three plague foci [Yulong: 0.19 (0.78) and 0.08 (0.07) mg/L; Jianchuan: 0.23 (0.56) and 0.03 (0.06) mg/L; Lianghe: 0.13 (0.61) and 0.09 (0.08) mg/L] were higher than that of "Environmental Quality Standards for Surface Water" (Pb: 0.10 mg/L, Cd: 0.01 mg/L). There were significant differences in the contents of Ca and Cd elements among the three regions ( P < 0.05), but there was no significant difference in the contents of the other 6 metal elements among the three regions ( P > 0.05). The content of Ca element was the highest in Yulong plague foci, and the lowest in Lianghe plague foci ( P < 0.017). In the Yulong plague foci, there was no statistically significant difference in the content of Fe element in different seasons ( P > 0.05), and the differences in the contents of the other 7 metal elements were statistically significant ( P < 0.05). There was no significant difference in the content of Cr element in Jianchuan plague foci in different seasons ( P > 0.05), and the differences in the content of the other 7 metal elements were statistically significant ( P < 0.05). There was no significant difference in the content of Ca element in Lianghe plague foci in different seasons ( P > 0.05), and the differences in the content of the other 7 metal elements were statistically significant ( P < 0.05). Conclusion:The metal element contents of Pb and Cd are relatively abundant in water samples from 3 plague foci of Yunnan Province, and the seasonal variation trend of metal element content in water samples of Yulong and Jianchuan plague foci is similar.

Objective To assess the change of sexual behaviors before and after HIV was recently identified among men who have sex with men(MSM). Methods A retrospective study was conducted on recently identified HIV-infected MSM in Chengdu and Tianjin. A face-to-face questionnaire interview was administrated to collect sexual behaviors within six months,before and after HIV was diagnosed. Differences in sexual behavior before and after the diagnosis were assessed, using the McNemar χ 2 test. Logistic regression analysis was conducted to identify predictors for sexually risk behaviors. Results Of 129 HIV-infected MSM under survey,the average age was 31.8 years and the main venue in seeking male sex partners was through Internet. The proportions of MSM with unprotected anal intercourse (UAI) decreased from 70.5% before diagnosis to 16.3% after diagnosis and the percentage of having more than 1 partner decreased from 66.7%before diagnosis to 33.3%after diagnosis. After the diagnosis was made,there appeared a significant decrease in the percentage of persons who had one main partner from 72.9% to 55.0% and having casual partners declined from 62.8% to 31.0%. Data from multiple logistic regression analysis revealed that risk factors as UAI before diagnosis,more than 1 partner after diagnosis and having one main partner,were all significantly associated with UAI after diagnosis. After the diagnosis was made for UAI,risk factors for‘having more than 1 partner’after diagnosis,would include:using Internet to seek for sexual partners,after diagnosis,having one main partner but not disclosing to him. Conclusion After the diagnosis was made,most HIV-infected MSM would reduce their high risk sexual behaviors but some continued to practice UAI.

We report a case of chromoblastomycosis caused by , which was successfully treated by long-pulsed 1064 nm Nd: YAG laser combined with terbinafine. A 60-year-old man was admitted for the presence of a 30 mm×40 mm erythematous plaque on the dorsum of his right hand for about 10 months without any subjective symptoms. Both microscopic examination and tissue biopsy of the lesion showed characteristic sclerotic bodies of chromoblastomycosis. Lesion tissue culture on SDA at 26 ℃ for 2 weeks resulted in a black colony, and slide culture identified the isolate as Fonsecaea species. ITS sequence analysis of the isolate showed a 99% homology with strain KX078407. The susceptibility of the isolate to 9 antifungal agents was determined using the microdilution method according to the guidelines of CLSI M38-A2 protocol, and terbinafine showed the lowest MIC (0.125 μg/ml). We subsequently established a Wistar rat model of chromoblastomycosis using the clinical isolate and treated the rats with long-pulsed 1064 nm Nd: YAG laser (pulse width of 3.0 ms, fluence of 24 J/cm, spot size of 3 mm, frequency of 4 Hz, repeated 3 times at an interval of 30 s) twice a week for a total of 8 sessions. Although the laser treatment alone was not able to eliminate the fungi, histopathological examination showed the aggregation of numerous lymphocytes in the local affected tissue, indicating an immune response that consequently facilitate the regression of the lesion. The patient was successfully treated by long-pulsed 1064 nm Nd: YAG laser once a week combined with terbinafine (0.25 /bid) for 8 weeks, and follow-up for 20 months did not reveal any signs of recurrence.
