Objective: To evaluate the effectiveness for the construction of "mosquito-free village" in Xuejia Village, Pujiang County, Zhejiang Province, so as to provide the guidance for the construction of "mosquito-free village" in other rural areas. Methods: Density of adult mosquitoes in Xuejia Village was investigated using light trap method and density of larval mosquitoes was investigated using larval straw method from April to November each year. Totally 30 households of villagers were randomly selected, and their awareness rates of mosquito control knowledge, mosquito control behavior forming rates and satisfaction rates were surveyed through questionnaires. Investment during construction (from August 2016 to December 2018) and maintenance period (from 2019 to 2023) of "mosquito-free village" were investigated through data review and interviews. Long-term effects of "mosquito-free village" construction in Xuejia Village were evaluated in terms of mosquito density from 2016 to 2023, effectiveness of health education for villagers, satisfaction and investment. Results: Compared with the year 2016, the densities of adult and larval mosquitoes in Xuejia Village were significantly decreased from 2017 to 2023. The average monthly density of adult mosquitoes in 2023 decreased by 98.34%, and the average monthly 100 household index of larval mosquitoes decreased by 98.45% compared to 2016. The average monthly density of adult mosquitoes from 2019 to 2023 was less than or equal to one mosquito per light trap in a night, and the average monthly 100 household index of larval mosquitoes was less than or equal to five places per 100 households. The awareness rate of mosquito control knowledge was 93.33%, the behavior forming rate was 86.67%, and the satisfaction rate was 90.00%. By December 2023, the total investment during construction and maintenance period was 450 thousand Yuan, with an average annual investment of 60.7 thousand Yuan and average annual investment of 206.61 Yuan per household. The average annual investment during maintenance period was 36.2 thousand Yuan, and the average annual investment per household was 109.70 Yuan. Conclusion The mosquito density, effectiveness of health education for villagers and satisfaction of "mosquito-free village" in Xuejia Village all meet the evaluation criteria of "mosquito-free village", and the investment is reasonable, making it suitable for promotion to other rural areas.

Objective To study the correlation between semen quality and bacterial infection in men with abnormal fer-tility,and provide clinical basis for guiding the reproductive health of men with abnormal fertility.Methods 200 male semen samples with abnormal fertility were collected,and then separated and cultured for 48 hours.According to the culture results,they were divided into three groups:the non-pathogenic group,the pathogenic group,and the sterile group.The bacterial resist-ance analysis of the pathogenic group was conducted,and the semen quality between each group was compared.Results After 48 hours of isolation and cultivation,200 semen samples had been tested,non-pathogenic bacteria was detected in 163 semen samples,accounting for 81.5% ;pathogenic bacteria was detected in 33 semen samples,accounting for 16.5% ;and bacteria was not detected in 4 semen samples,accounting for 2.0% .The top three strains of pathogenic bacteria in 33 cases were Escherichia coli,Streptococcus agalactiae,and Enterococcus faecalis,with drug resistance rates of 80.0% ,87.5% ,and 100.0% ,respec-tively.Conclusion The detection rate of bacterial culture in semen of men with abnormal fertility is relatively high,and patho-genic bacteria can affect semen quality.

Objective To evaluate the intraoperative identification of ectopic parathyroid tissue in the central neck region using autofluorescence point-spectral analysis(AFPSA)combined with immune colloidal gold technique(ICGT),for guiding total parathyroidectomy(TPTX)or clean parathyroidectomy(CPTX)in the management of secondary hyperparathyroidism(SHPT).Methods Retrospectively collected and compared the clinical data of 64 patients with SHPT from October 2019 to June 2023.In the observation group,TPTX was performed as the initial procedure in 36 cases,followed by sampling of suspicious targets using AFPSA in the central neck area and subsequent detection through ICGT.CPTX was then conducted if a positive result was obtained.On the other hand,the control group consisted of 28 cases where only TPTX was performed without any additional tests during surgery.The surgical data,parathyroid hormone(PTH)levels,blood calcium levels,blood phosphorus levels,alkaline phosphatase(ALP)levels,regression of clinical symptoms,changes in parathyroid function and occurrence of hypocalcemia were compared between these two groups.Results In the observation group,there were 9 cases of AFPSA-ICGT positivity,including 2 left-sided cases,4 right-sided cases,and 3 thymic cases;among these posi-tive cases,there were a total of 10 locations with mildly hyperplastic or nonhyperplastic microscopic parathyroid tissue.The difference in the number of total parathyroid glands removed(including ectopic)between the two groups was statistically significant(P<0.05).At both 3 and 6 months postoperatively,ALP levels in the observation group were significantly lower than those in the control group(P<0.01 and P<0.001 respectively);at 6 months postoperatively,differences in PTH and blood phosphorus levels between the two groups were also statistically significant(P<0.05 and P<0.001 respectively).Joint bone pain and skin itching recurred in some patients within the control group at six months after surgery(P<0.05),whereas recurrence of SHPT was less frequent within the observation group compared to controls(P<0.05);however,no statistically significant differences were observed regarding postoperative hypoparathyroidism or hyperparathyroidism as well as hypocalcemia between either groups.Conclusion The AFPSA-ICGT intraoperative test can be utilized to guide surgery for SHPT,enabling accurate and efficient identification as well as safe targeting of parathyroid tissues that may not exhibit obvious hyperplasia in the central cervical region.

Metabolic syndrome (MS) is a set of clinical symptoms characterized by multiple concurrent metabolic disorders, and is an important risk factor for type 2 diabetes and cardiovascular diseases in individuals. Its pathogenesis is still unclear, and may be associated with insulin resistance, chronic inflammatory reactions and oxidative stress. Studies have shown that MS is closely related to papulosquamous skin diseases, skin adnexal diseases, dermatitis and eczematous skin diseases, pigmentary skin disorders and so on. This review summarizes the relationship between MS and related skin diseases.

Mosquito control and "mosquito-free village" construction in rural areas played positive roles in preventing mosquito-borne diseases and improving rural living environments. However,there was a lack of the target and specific evaluation system for mosquito control and prevention in rural areas. Based on the main contents of mosquito control works in rural areas,the national standards for mosquito control and practical experiences for“mosquito-free village”construction in Zhejiang Province,we built a evaluation system suitable for mosquito control in rural areas,in order to provide reference for the evaluation standard and the sustainable development of mosquito control in rural areas. This evaluation system included four indices named mosquito density control,village administration,health education and the villagers' attitude;each index had three levels named A,B and C from high to low. When all the four indices were evaluated as C,the village was regarded as basically meeting the requirements of mosquito control;when all the four indices were evaluated as A,the village was regarded as a "mosquito-free village".

Objective To investigate risk factors for and clinical features of steroid-induced diabetes mellitus due to glucocorticoid treatment.Methods Clinical data were collected from 798 patients who received systemic glucocorticoid treatment in Department of Dermatology of Hangzhou Third People's Hospital from 2013 to 2016,and analyzed retrospectively.Logistic regression analysis was performed to analyze the factors influencing the occurrence of steroid-induced diabetes mellitus (SDM),repeatedmeasures analysis of variance to compare peripheral blood glucose levels of patients with SDM after breakfast,lunch and dinner,and t test to compare the levels of fasting blood glucose and glycosylated hemoglobin (HbA1 c) between patients with SDM and those with type 2 diabetes mellitus.Results Of the 798 patients,38 developed SDM due to glucocorticoid treatment.The average age was significantly older in the patients with SDM ([66.86 ± 13.30] years,n =38) than in those without SDM ([39.95 ± 17.01] years,n =760;t =8.86,P ＜ 0.01),but there was no significant difference in the gender ratio between the patients with and thhose without SDM (x2 =1.61,P =0.20).The prevalence of fatty liver,hyperlipidemia,hypertension,abnormal liver function and family history of diabetes mellitus was significantly higher in the patients with SDM than in those without SDM (x2 =12.25,19.25,32.69,21.47,16.70 respectively,all P ＜0.01).Logistic regression analysis showed that age,fatty liver,hyperlipidemia,hypertension,abnormal liver function,dosage of glucocorticoids,duration of glucocorticoid therapy,use of immunosuppressive agents and family history of diabetes mellitus were risk factors for SDM (all P ＜ 0.05).There were no significant differences in fasting blood glucose levels or postprandial peripheral blood glucose levels among the SDM patients receiving glucocorticoid therapy at different dosages of 0.50-0.74,0.75-0.99,1.00-1.25 mg·kg-1· d-1 (P ＞ 0.05).The peripheral blood glucose levels after breakfast,lunch and dinner were (11.50 ± 2.90),(16.02 ± 5.81) and (16.81 ± 4.52) mmol/L respectively in the patients with SDM.The levels of fasting blood glucose and glycosylated HbA 1 c were both significantly lower in the patients with SDM than in those with type 2 diabetes mellitus (t =3.74,9.92 respectively,both P ＜ 0.001).Conclusions The risk factors for SDM are age,dosage of glucocorticoids,duration of glucocorticoid therapy,fatty liver,hyperlipidemia,hypertension,abnormal liver function,use of immunosuppressive agents and family history of diabetes mellitus.The patients with SDM showed obviously elevated blood glucose levels mostly after lunch and dinner,but slightly increased levels of fasting blood glucose and glycosylated HbA 1c,which can be used to distinguish between SDM and type 2 diabetes mellitus.
