ObjectiveTo investigate the infection and genotypes of Wolbachia in Aedes albopictus. MethodsAdult and larval samples of Aedes albopictus were collected from different residential and wild areas from 2020 to 2021， Wolbachia surface protein （wsp） gene was amplified and genotyped for wAlbA and wAlbB by PCR， and sequenced for phylogenetic analysis. The difference of detection rate among different habitats， male and female adult mosquitoes， adult and larvae was compared by χ² analysis. ResultsThe detection rate of Wolbachia in adult and larvae of Aedes albopictus were 43.5% （77/177） and 70.4% （190/270）， respectively， with a statistically significant difference （χ²=32.086，P<0.001）， and wAlbA and wAlbB were mainly detected together. The detection rate of Wolbachia in female and male Aedes albopictus were 50.7% （76/150） and 3.7% （1/27）， respectively， with a statistically significant difference（χ²=20.533，P<0.001）. The detection rate of adult Aedes albopictus in Songjiang wild area， residential area and Hongkou residential area were 91.7% （55/60）， 18.8% （22/117） and 41.7% （30/72）， respectively， with a statistically significant difference （χ²=54.322，P<0.001）. Genotyping and phylogenetic analysis showed that adult and larvae of Aedes albopictus infected with Wolbachia were mainly wAlb A and wAlb B. In addition， some sequences formed clades independently， and the genetic distance from other sequences was relatively large. ConclusionInfection of Wolbachia in Aedes albopictus is relatively common in Songjiang District. The main genotypes are wAlb A and wAlb B and there may be other subtypes， which are worthy of further exploration and research.

ObjectiveTo investigate the relationship between mosquito density fluctuations and meteorological factors, so as to provide a scientific basis for mosquito surveillance analysis, risk assessment, and comprehensive prevention and control. MethodsMosquito surveillance and monitoring data of 2020‒2023 was obtained from on-site supervisory sampling by Songjiang Center for Disease Control and Prevention, and meteorological data was obtained from the Wheat A wheat malt-agro-meteorological big data system. Excel 2019 and SPSS 25.0 software were used to organize and analyze the mosquito number, species composition, and seasonal changes in mosquito density captured by the CO₂-light trap at rach monitoring site. Circular distribution method was used to calculate the peak time of mosquito density, combined with the meteorological data of the same period to explore the impact of meteorological factors on the results of mosquito surveillance. ResultsThere was a statistical difference in the overall distribution of mosquito quantity in different habitats(H=23.11, P<0.05), 2020‒2023. In addition, the results showed that July 28th was the peak day for mosquito density, and the duration from June 13th to September 11th was the seasonal peak period for mosquitoes. Pearson correlation analysis showed a positive correlation between mosquito density and average air temperature, average highest air temperature, average lowest air temperature, extreme maximum air temperature, extreme minimum air temperature, precipitation, and number of precipitation days (all P<0.01). While, there was no significant correlation between average wind speed and mosquito density (P>0.05). Multiple stepwise regression analysis resulted in the equation of Y=0.151X_{extreme minimum temperature}+0.321X_{number of precipitation days}+1.002X_{SQRT precipitation}-1.288 (F=102.635, P<0.05). ConclusionThe CO₂-light trap is advisable to monitor the habitats of farmers, livestock sheds, residential areas, parks, hospitals, and other external environments. Air temperature and precipitation have a significant impact on mosquito density. It is recommended to implement comprehensive prevention and control measures to reduce mosquito density and prevent mosquito-borne diseases before the peak period of mosquitoes.

Objective Based on mosq-ovitrap monitoring method of Aedes albopictus， to determine the spatial and temporal distribution of Aedes albopictus in Songjiang District and provide scientific evidence for prevention and control of mosquito-borne diseases. Methods From May to October， 2018‒2020， density of Aedes albopictus was monitored by using the mosq-ovitrap method. Sub-districts and towns were used as the monitoring units and the difference in mosquito ovitrap index （MOI） was compared by seasons， years and habitats. Results The total number of positive mosquito ovitraps was 1049 in 2018‒2020， and the average MOI was 8.10. Four sub-districts/towns in the urban area and the northern area had the relatively high MOIs. Moreover， MOIs in residential and external environments were higher than other habitats. In addition， MOI of Aedes albopictus decreased over years from 2018 to 2020. Conclusion Aedes albopictus is widely distributed in Songjiang District. Although the number of mosquito decreased over years after the implementation of mosquito control measures， reproduction of mosquito remains excessive in some areas and seasons. It is necessary to perform targeted control measures based on comprehensive monitoring methods.

Objective:To investigate the clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) on therapy-related leukemia (TRL).Methods:The clinical data of 14 patients with TRL who received allo-HSCT in Aerospace Central Hospital from April 2012 to February 2020 were retrospectively analyzed, and the therapeutic efficacy and survival status were also analyzed.Results:Of the 14 patients, 5 were males and 9 were females; the median age was 35 years old (12-59 years old). There were 12 patients with acute myeloid leukemia, 1 patient with chronic lymphocytic leukemia/small cell lymphoma, and 1 patient with acute lymphoblastic leukemia. At the time of transplantation, 4 patients achieved bone marrow complete remission, 3 patients achieved bone marrow partial remission, and the remaining 7 patients had no remission. Five patients received HLA-matched sibling transplantation, 9 patients received haplotype transplantation, and they all received myeloablative pretreatment schemes. All 14 patients were successfully implanted; the median engraftment time of granulocyte was 16 d (10-24 d), and the median engraftment time of platelet was 13 d (10-34 d). Grade Ⅰ-Ⅱ acute graft-versus-host disease (GVHD) occurred in 7 patients, chronic GVHD occurred in 6 patients, and grade Ⅲ intestinal GVHD occurred in 2 patients. The median follow-up time was 32 months (4-97 months). Among 14 patients, 5 patients died.Conclusion:The allo-HSCT can improve the prognosis and long-term survival rate of TRL patients.

Objective To investigate the effect of dexmedetomidine pretreatment on Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway during myocardial injury induced by liver ischemia-reperfusion (I/R) in rats.Methods Twenty-four healthy adult male SpragueDawley rats,aged 8-10 weeks,weighing 220-250 g,were divided into 3 groups (n=8 each) using a random number table method:sham operation group (group S),liver I/R group (group I/R),and dexmedetomidine pretreatment group (group D).The portal vein,superior and inferior vena cava,subhepatic inferior vena cava and hepatic artery were clamped,and the liver was perfused with 4 ℃ lactated Ringer's solution for 60 min through the portal vein to establish the model of liver cold I/R in anesthetized rats.Dexmedetomidine 100 μg/kg was intraperitoneally injected at 30 min before ischemia in group D.Blood samples were collected at 8 h of reperfusion from the inferior vena cava for determination of serum cardiac troponin Ⅰ (cTnⅠ) and heart-type fatty acid binding protein (H-FABP) concentrations (using the automatic biochemistry analyzer),tumor necrosis factor-alpha (TNF-α) and high-mobility group box 1 protein (HMGB1) concentrations (by enzyme-linked immunosorbent assay).The rats were then sacrificed,andhearts were harvested for examination of histopathological changes (with a light microscope) and for determination of the malondialdehyde (MDA) content (using thiobarbituric acid method) and superoxide dismutase (SOD) activity (by xanthine oxidase method),and expression of phosphorylated STAT1 and STAT3 (p-STAT1,p-STAT3) and phosphorylated JAK2 (p-JAK2) in myocardial tissues (by Western blot).Results Compared with group S,the serum concentrations of cTnI,H-FABP,TNF-α and HMGB1 were significantly increased,the MDA content was increased,the SOD activity was decreased,and the expression of p-JAK2,p-STAT1 and p-STAT3 was up-regulated in I/R and D groups (P＜0.05).Compared with group I/R,the serum concentrations of cTnI,H-FABP,TNF-α and HMGB1 were significantly decreased,the MDA content was decreased,the SOD activity was increased,the expression of pJAK2,p-STAT1 and p-STAT3 was down-regulated (P＜0.05),and pathological changes of myocardium were significantly attenuated in group D.Conclusion The mechanism by which dexmedetomidine pretreatment mitigates myocardial injury induced by liver cold I/R may be related to inhibiting activation of JAK/STAT signaling pathway in rats.

BACKGROUND:How to make more transplanted bone marrow stem cel s stay and differentiate in the liver is an important issue, which is also crucial for treatment of liver cirrhosis via the hepatic artery.
OBJECTIVE:To investigate the therapeutic effect of autologous bone marrow stem cel transplantation via the hepatic artery on liver cirrhosis.
METHODS:Thirty New Zealand white rabbits were equivalently randomized into normal control, stem cel transplantation and model groups. Animal models of liver cirrhosis were made in the latter two groups. Then, model rabbits in the stem cel transplantation group were subjected to autologous bone marrow stem cel transplantation via the hepatic artery. Liver function of rabbits was detected in 1, 2, 4, 8, 10 weeks after cel transplantation, and pathological detection of the liver was performed in the 10th week.
RESULTS AND CONCLUSION:At 10 weeks after cel transplantation, the liver function of the rabbits was improved significantly compared with the model group, including reduced activities of serum alanine aminotransferase, total bilirubin and aspartate aminotransferase, shortened activated partial thromboplastin time, and increased albumin level (P<0.05). Pathological examination of the liver showed that the liver cel s in the stem cel transplantation group were intact with no obvious edema and stil had the structure of the pseudolobule, and compared with the model group, the degree of liver fibrosis was significantly reduced in the stem cel transplantation group. Our experimental results show that the transplantation of autologous bone marrow stem cel s via the hepatic artery has a certain therapeutic effect on liver cirrhosis by increasing the body albumin content in a short time and improving the liver function.
