Objective To investigate the current distribution and predict the future suitable habitats of Haemaphysalis longicornis in Nanjing City, so as to provide insights into control and early warning of ticks and management of tick-borne diseases in Nanjing City. Methods The electronic map of Nanjing City was obtained from the National Platform for Common GeoSpatial Information Services. The distribution of H. longicornis and the longitude and latitude of distribution points from 2022 to 2024 were obtained from centers for disease control and prevention across each district in Nanjing City. Climatic and environmental variable data in Nanjing City were captured from the Worldclim database. Initially, 19 bioclimatic variables in this database were selected, including annual mean temperature, mean diurnal range, isothermality, temperature seasonality, maximum temperature of the warmest month, minimum temperature of the warmest month, temperature annual range, mean temperature of the wettest quarter, mean temperature of the driest quarter, mean temperature of the warmest quarter, mean temperature of the coldest quarter, annual precipitation, precipitation of the wettest month, precipitation of the driest month, precipitation seasonality, precipitation of the wettest quarter, precipitation of the driest quarter, precipitation of the warmest quarter, and precipitation of the coldest quarter. The elevation and normalized difference vegetation index were obtained from Data Sharing Platform of the Center for Resources and Environmental Sciences, Chinese Academy of Sciences. Then, the distribution points of H. longicornis, elevation, vegetation index and 19 bioclimatic variables were loaded into the software MaxEnt 3.4.4 to evaluate and screen out the variables with a contribution rate of 1% and higher. ArcGIS 10.8.1 software was used to extract the elevation, vegetation index and 19 bioclimatic variables of the distribution points of H. longicornis for a correlation analysis. If the absolute value of the correlation coefficient was 0.8 and higher, the variable with the higher contribution was retained. The 2050 dataset of the BCCCSM2-MR atmospheric circulation model in the coupled model intercomparison project phase 6 (CMIP6) were obtained from the Worldclim database as climate data for 2050. Screened H. longicornis species data and environmental and climate data were loaded into the maximum entropy (MaxEnt) model with the software MaxEnt 3.4.4 for training and validation, and then, all data generated from the model were imported into the software ArcGIS 10.8.1 to generate raster data and yield the map pertaining to the distribution of H. longicornis risk in Nanjing City. The accuracy of the model was evaluated with a receiver operating characteristic (ROC) curve, and the predictive effect of the model was assessed with area under the ROC curve (AUC). The suitable habitats of H. longicornis were classified in Nanjing City with the software ArcGIS 10.8.1, and the areas of distribution of suitable habitats in various categories were recorded to create the map of current H. longicornis suitable habitats classification in Nanjing City. The climatic and geographic information data in 2050 were employed as future environmental and climatic factors, and current environmental and climatic factors and current H. longicornis distribution data were additionally used to predict the future suitable habitats of H. longicornis in Nanjing City. In addition, the contributions of environmental and climatic factors to distribution of suitable habitats of H. longicornis was evaluated with the Jackknife method in Nanjing City. Results A total of 10 environmental and climatic variables were screened for analysis of the suitability of H. longicornis in Nanjing City based on correlation analyses and contributions of the MaxEnt model, including annual mean temperature, precipitation of the warmest quarter, vegetation index, precipitation of the wettest month, temperature annual range, annual precipitation, mean temperature of the warmest quarter, elevation, mean temperature of the wettest quarter, and maximum temperature of the warmest month, and annual mean temperature (34.8%), precipitation of the warmest quarter (17.3%), vegetation index (13.1%), and precipitation of the wettest month (10.8%) contributed relatively highly to the distribution of suitable habitats of H. longicornis in Nanjing City. The mean AUC of the ROC curve was 0.810 ± 0.055 for 10 repeated modeling results of the MaxEnt model, indicating high predictive performance of the model. The potential distribution areas of H. longicornis were predicted to be mainly located in Luhe District, Pukou District, Jiangning District, Lishui District, and Gaochun District in Nanjing City with the MaxEnt model. Under current climatic conditions, the area of potential suitable habitats of H. longicornis was 4 182.42 km² in Nanjing City, including 1 252.94 km² highly suitable habitats, which accounted for 19.00% of the total area of Nanjing City. Under the climate scenario in 2050, the area of potential suitable habitats of H. longicornis was projected to increase to 5 467.58 km² in Nanjing City, accounting for 82.95% of the total area of the city, and these habitats were mainly concentrated in Luhe District, Pukou District, Jiangning District, Lishui District, and Gaochun District. The areas of suitable habitats of H. longicornis at various categories were predicted to vary greatly in 2050, and the area of highly suitable habitats of H. longicornis was projected to increase to 2 378.82 km², accounting for 36.08% of the total area of Nanjing City. Based on jackknife tests and contributions of environmental and climatic variables, 6 dominant environmental and climatic factors were screened, including annual mean temperature (34.8% contribution), precipitation of the warmest quarter (17.3% contribution), vegetation index (13.1% contribution), precipitation of the wettest month (10.8% contribution), temperature annual range (5.4% contribution), and mean temperature of the warmest quarter (5.0% contribution), with cumulative contributions of 86.4%. Conclusion The distribution of H. longicornis is strongly associated with vegetation, temperature and precipitation in Nanjing City. Future climate change may lead to an expansion of the distribution area of H. longicornis in Nanjing City.

Objective:To evaluate the role of nemo-like kinase (NLK) in lipopolysaccharide (LPS)-induced inflammatory responses of mouse bone marrow-derived macrophages (BMDMs) and the relationship with glycolysis.Methods:BMDMs were extracted from the wild type (WT) and NLK knockout (NLK -/-) C57BL/6 mice of either sex, aged 6-8 weeks, weighing 20-25 g, were used in this study. After induction, differentiation, maturation and purity identification, BMDMs were divided into phosphate buffer solution (PBS) control group (WT+ PBS group, NLK -/-+ PBS group, n=18) and LPS group (WT+ LPS group, NLK -/-+ LPS group, n=18) by a random number table method. LPS at a final concentration of 1 μg/ml was added to stimulate mature BMDMs for 6 h in LPS group, while the equal volume of PBS was given instead in PBS group. The cell viability was measured by Calcein/PI staining, and the expression of cellular NLK, inflammatory factors (tumor necrosis factor-alpha [TNF-α], interleukin-1 beta [IL-1β] and IL-6) and key glycolytic enzymes (hexokinase 2 [HK2], pyruvate kinase M2 (PKM2) and lactate dehydrogenase A [LDHA])mRNA was detected by real-time fluorescent quantitative polymerase chain reaction. Western blot was used to detect the expression of NLK, HK2, PKM2 and LDHA. The concentrations of TNF-α, IL-1β and IL-6 in the supernatant were determined by enzyme-linked immunosorbent assay. Glucose uptake and lactic acid production were measured by hexokinase method and colorimetric method respectively. Results:Compared with WT-type BMDMs, the expression of NLK protein and mRNA in NLK -/--type BMDMs was significantly down-regulated ( P<0.05). Compared with WT+ PBS group, the BMDM viability was significantly decreased, the expression of TNF-α, IL-1β and IL-6 was up-regulated, the concentrations of TNF-α, IL-1β and IL-6 in the supernatant were increased, the expression of NLK, HK2, PKM2 and LDHA protein and mRNA was up-regulated, and the glucose uptake and lactic acid production were increased in WT+ LPS group ( P<0.05). Compared with WT+ LPS group, the BMDM viability was significantly increased, the expression of TNF-α, IL-1β and IL-6 was down-regulated, the concentrations of TNF-α, IL-1β and IL-6 in the supernatant were decreased, the expression of NLK, HK2, PKM2 and LDHA protein and mRNA was down-regulated, and the glucose uptake and lactic acid production were decreased in NLK -/-+ LPS group ( P<0.05). Conclusions:NLK may enhance LPS-induced inflammatory responses of BMDMs by promoting glycolysis in BMDMs of mice.

Objective:To investigate the relationship between the level of angiotensin Ⅱ type 1 receptor autoantibody (AT1-AA) in the uterine fluid and the thickness of endometrium in infertile women with chronic endometritis.Methods:A case-control study was conducted to select 122 patients who underwent hysteroscopy and endometrial tissue biopsy at Assisted Reproduction Center, Taiyuan Central Hospital due to infertility from March 2023 to January 2024 as the study subjects. According to the results of hysteroscopy and endometrial tissue biopsy, the patients were divided into 52 cases in the infertility group with normal endometrium (NE infertility group) and the chronic endometritis combined with infertility group (CE infertility group) with 70 cases. Enzyme-linked immunosorbent assay was used to detect the level of AT1-AA in uterine fluid of the two groups. General clinical data, AT1-AA absorbance value of uterine fluid and uterine related indexes of the two groups were analyzed, and the correlations between AT1-AA level and the variation of indexes were analyzed.Results:Gravidity (median: 1 vs 1; Z=7.029, P=0.030) and parity (median: 0 vs 0; Z=12.258, P=0.002) in CE infertility group were higher than those in NE infertility group. There was AT1-AA in the uterine fluid, and the level of AT1-AA in CE infertility group was significantly higher than that in NE infertility group (median: 2.07 vs 1.44; Z=3.099, P=0.029). The endometrial thickness of CE infertility group was lower than that of NE infertility group (median: 6.0 vs 7.0 mm; Z=-2.179, P=0.029), and there were no statistical differences in other indexes between the two groups (all P>0.05). Further correlation analysis showed that there were no correlation between the level of AT1-AA in uterine fluid and parity, endometrial thickness, gravidity in NE infertility group (all P>0.05). However, the level of AT1-AA in uterine fluid of CE infertility group was positively correlated with parity (Spearman′s r=0.339, P=0.004), and negatively correlated with endometrial thickness (Spearman′s r=-0.499, P<0.001), but not correlated with gravidity ( P>0.05). Conclusions:AT1-AA is present in the uterine fluid of infertile women. The elevated level of AT1-AA in uterine fluid of infertile women with CE is related to the thinning of the endometrium.

Objective:To investigate the efficacy and safety of percutaneous trans-hepatic choledochoscopic lithotripsy (PTCSL) in the treatment of recurrent hepatobiliary calculi under enhanced recovery after surgery (ERAS) mode.Methods:Clinical data of 88 patients with recurrent hepatobiliary calculi, who were treated with PTCSL at Zhengzhou Central Hospital Affiliated to Zhengzhou University and the First Affiliated Hospital of Xi'an Jiaotong University between June 2022 and June 2024 were retrospectively analyzed, including 34 males and 54 females, aged (52.0±13.8) years. The scheme includes preoperative education, prophylactic antibiotic application, ensuring the quality of surgery, early postoperative feeding and activity, etc. The operation can be divided into two fashions: percutaneous transhepatic cholangial drainage and PTCSL, which can be completed in one stage (one-stage expansion method) or in two stages (staged expansion method). Clinical data such as gender, age, operative time, intraoperative blood loss, residual stone, and surgical complications were recorded.Results:All 88 patients underwent PTCSL under ERAS mode successfully, including 52 cases using one-stage expansion method and 36 cases using staged expansion method. The operative time was (53±20) min, the intraoperative blood loss was (9.7±3.8) ml, the postoperative hospital stay was (3.6±1.7) d, and the hospitalization cost was (17 500±4 700) yuan. Sixty-nine patients (78.4%, 69/88) had one-time stone removal in the first PTCSL. A total of 19 cases of residual stones were managed again by percutaneous sinus soft choledochoscopy, of which 12 cases were managed by one-time choledochoscopy, five cases by two-time choledochoscopy, and two cases by three-time choledochoscopy. The rate of residual stone was significantly higher in one-stage expansion method compared to staged expansion method [28.8% (15/52) vs. 11.1% (4/36), P=0.040]. No death, conversion to open surgery, or severe complications such as intra-abdominal hemorrhage or bile leakage occurred in the patients. No residual stones or recurrence were found during the follow-ups of (7.5±2.1) months after discharge. Conclusion:PTCSL under ERAS mode is safe and effective in the treatment of recurrent hepatobiliary calculi.

Objective:To investigate the presence of angiotensin Ⅱ type 1 receptor autoantibodies (AT1-AA) in follicular fluid, and to investigate the correlation between AT1-AA levels and follicular development in follicular fluid of infertile patients with polycystic ovary syndrome (PCOS).Methods:A case-control study was conducted on 182 infertile patients who underwent in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) at the Center for Reproductive Medicine of Taiyuan Central Hospital from June 2021 to October 2022. There were 80 cases in the fallopian tube factor group (tubal factor group) and 102 cases in PCOS infertility group (PCOS group). Univariate analysis was performed for the general data, ovulation induction indexes and embryonic laboratory indexes of the two groups. Enzyme-linked immunosorbent assay (ELISA) was used to detect the level of AT1-AA in follicular fluid on the day of oocyte retrieval. Pearson or Spearman was used to analyze the correlation between AT1-AA level and follicle development indexes, and multiple linear regression was used to adjust for interfering factors to analyze the correlation between AT1-AA level and embryonic laboratory indicators. Results:Body mass index [BMI, (25.29±3.25) kg/m 2], antral follicle count [AFC, 24.00 (17.00, 24.00)], basal serum teststerone [0.50 (0.36, 0.79) μg/L] and anti-Müllerian hormone [AMH, 4.92 (2.57, 8.28) μg/L] in PCOS group were significantly higher than those in tubal factor group [(23.01±2.92) kg/m 2, P<0.001; 15.00 (10.25, 19.00), P<0.001; 0.38 (0.20, 0.59) μg/L, P=0.019; 3.06 (2.19, 4.89) μg/L, P=0.006]. Moreover, the AT1-AA P/N value in follicular fluid in PCOS group [4.24 (2.07, 8.89)] was significantly higher than that in tubal factor group [2.96 (1.86, 4.84), P=0.027]. In addition, the age of menarche in PCOS group [13.00 (12.00, 14.00) years] was earlier than that in tubal factor group [14.00 (13.00, 15.00) years, P=0.007]. Prolactin level [12.09 (9.65, 16.64) μg/L] was lower than that of tubal factor group [16.27 (12.86, 20.94) μg/L, P=0.002], and there were no statistical differences in other indexes between the two groups (all P>0.05). Correlation analysis showed that the level of AT1-AA in follicular fluid of PCOS patients was negatively correlated with oocyte retrieval rate ( r=-0.159, P=0.019). The results of multiple linear regression analysis showed that AT1-AA level in follicular fluid was negatively correlated with oocyte retrieval rate ( β=-0.598, P=0.028) and normal fertilization rate ( β=-0.527, P=0.022) after adjusting for confounding factors. Conclusion:The level of AT1-AA in follicular fluid in PCOS patients is significantly higher than that in patients with tubal infertility, and is negatively correlated with oocyte retrieval rate and normal fertilization rate.
