Objective To understand mosquito density, species composition, and seasonal variations around the Beijing Capital International Airport(BCIA)and provide scientific evidence for mosquito-borne disease prevention and control. Methods Meteorological data were collected from 2016 to 2022, and mosquito density was monitored at seven surveillance sites around the BCIA from May to October each year using CO2-baited mosquito traps to analyze the relationship between mosquito density and meteorological factors. Results In total,68 518 female mosquitoes were captured, with a mosquito density of 10.20 per light · hour. The dominant species was Culex pipiens pallens(73.90%), followed by Aedes albopictus(9.71%)and Ae. vexans(9.29%);the mosquito density was highest in 2016(14.8 per light·hour)and lowest in 2022(4.46 per light·hour). Significant statistical differences were observed in mosquito density among different species(F=18.118, P<0.05). The density of Cx. pipiens pallens and other mosquito species showed a mutually exclusive trend; the peak of mosquito density varied based on years and habitats, with significant statistical differences in mosquito density among different habitats(F=8.504, P<0.05). The highest mosquito density was observed near the Wenyu River(21.50 per light·hour), whereas the lowest was recorded at the BCIA construction site(2.44 per light· hour). The monthly average temperature(r=0.595), monthly average highest temperature(r=0.575), and monthly average lowest temperature(r=0.624)showed moderate positive correlations, whereas the monthly average air pressure(r=-0.484)showed a moderate negative correlation. The monthly average minimum temperature was included in the regression model(F=25.575, P<0.000), and the equation Y=1.029X4-8.181 was used. The monthly average air pressure 2 months prior(b=-2.418, β=-1.619, P<0.05)and the monthly average relative humidity(b=-0.739, β=-1.201, P<0.05)significantly negatively predicted the mosquito density. Notably, the regression equation used was y=2526.170+(-2.418)X9+(-0.739)X13. The exposure-response analysis revealed that the density of mosquitoes was not linearly related to the average monthly air pressure, rainfall, and duration of sunshine. Conclusions The dominant mosquito species around the BCIA was Cx. pipiens pallens, Ae. albopictus, and Ae. vexans. During the control of Cx. pipiens pallens, the impact on other mosquito species must also be considered. Environmental management, breeding sites, and scientific use of pesticides should be prioritized based on the activity periods of mosquitoes. Further studies on mosquitoes and meteorological factors should be conducted to provide references and novel avenues for mosquito control.

Objective To evaluate the effectiveness of thermal tomography in breast cancer (BC) screening. Methods We conducted a general population-based BC screening in three regions of Hubei Province (Xiantao, Hongan, and Yangxin Districts). Participants underwent a questionnaire-based interview for baseline data collection. They then received a physical examination, thermal tomography, and ultrasound from doctors and technicians. We compared the efficacies, including sensitivity, specificity, and false-positive rates, of ultrasound and thermal tomography in BC screening. Results A total of 59 712 eligible women were included in this screening program. The BI-RADS 1, 2, 3, 4, and 5 accordance rates between the two screening methods were 0.9549, 0.8047, 0.9037, 0.3352, and 0, respectively. The overall accordance rate was 0.933 1. The kappa consistency results showed that the Cicchetti-Allison and Fleiss-Cohen kappa values were 0.7970 and 0.8583, respectively. Although the two methods had equal sensitivities, specificity was higher in thermal tomography than in ultrasound. The false-positive rate was lower in thermal tomography than in ultrasound. The area under the receiver operating characteristic (ROC) curve of thermal tomography was significantly larger than that of ultrasound. Conclusion The general consistency between thermal tomography and ultrasound in BC screening was high. Thermal tomography outperformed ultrasound in terms of specificity and diagnostic efficiency. Therefore, thermal tomography has a high application value for general population-based BC screening.

As the number of patients with compromised immune function increases and fungal resistance develops, so does the risk of contracting deadly fungi in humans. Both fungi and humans are eukaryotes, so identifying unique targets for antifungal drug development is difficult. In addition, the existing antifungal drugs are limited by toxicity, drug interaction and drug resistance in practical application, which leads to the increasing incidence and fatal rate of fungal infections. Therefore, it is urgent to develop new antifungal drugs. The semi-synthetic technology using microbial fermentation products from natural sources as lead compounds has become the most used method in structural modification of antifungal drugs due to its advantages of few reaction steps and easy operation. This paper will introduce the current status of natural antifungal drugs in clinical use, as well as the latest progress in the research and development of new semi-synthetic antifungal drugs, and summarize their mechanism of action, structural modifications, advantages and disadvantages, so as to provide reference for the subsequent development of new antifungal drugs.

OBJECTIVE: Glucocorticoid-induced osteoporosis (GIOP) is a common complication of prolonged glucocorticoid therapy. Chlorogenic acid (CGA), a polyphenol with antioxidant properties that is extracted from traditional Chinese medicines such as Eucommiae Cortex, has potential anti-osteoporotic activity. This study aimed to investigate the possible effects of CGA on GIOP in mice and murine long bone osteocyte Y4 (MLO-Y4) cells and explore the underlying molecular mechanisms. METHODS: The protective effects of CGA were initially evaluated in the GIOP mouse model induced by dexamethasone (Dex). The micro-computed tomography, hematoxylin-eosin staining, silver nitrate staining, and serum detection were used to assess the efficacy of CGA for improving bone formation in vivo. Then, network pharmacology analysis was used to predict the potential targets and molecular mechanisms underlying the therapeutic efficacy of CGA against GIOP. After that, 2',7'-dichlorofluorescein diacetate staining, flow cytometry, real-time quantitative reverse transcription polymerase chain reaction, and Western blotting were used to verify the mechanisms of CGA against GIOP in vitro. RESULTS: Animal experiments showed that CGA treatment effectively attenuated Dex-induced decreases in bone mass and strength and improved disrupted osteocyte morphology in mice. The protein-protein interaction analysis highlighted erb-b2 receptor tyrosine kinase (ERBB2), which is also known as human epidermal growth factor receptor 2 (HER2), caspase-3, kinase insert domain receptor, matrix metallopeptidase 9, matrix metallopeptidase 2, proto-oncogene tyrosine-protein kinase Src, and epidermal growth factor receptor as core targets. The Kyoto Encyclopedia of Genes and Genomes analysis revealed several significantly enriched pathways (P < 0.05), including the ERBB, phosphoinositide 3 kinase-AKT serine/threonine kinase 1 (AKT), and mechanistic target of rapamycin kinase (mTOR) pathways. Cellular experiments verified that CGA enhanced bone formation and promoted autophagy while inhibiting apoptosis in MLO-Y4 cells exposed to Dex, which was associated with the upregulated expression of HER2 and activation of the HER2/AKT/mTOR signaling pathway. CONCLUSION CGA exerted anti-osteoporotic effects against GIOP, partially through targeting osteocytes and modulating the HER2/AKT/mTOR signaling pathway.

AIM: To observe the efficacy of intravitreal Conbercept injection(IVC)in diabetic neovascular glaucoma(NVG).METHODS:Retrospective study. Totally 57 patients(57 eyes)with NVG(stage II)secondary to proliferative diabetic retinopathy(PDR)treated in our hospital were collceted from January 2019 to December 2022. Among them, 30 patients(30 eyes)were treated by IVC and panretinal photocoagulation(PRP)in the observation group, and 27 patients(27 eyes)were treated by PRP in the control group. The best corrected visual acuity(BCVA, LogMAR), intraocular pressure, neovascularization of the iridocorneal angle(NVA), central macular thinkness(CMT)changes and disease progression were analyzed with a follow-up of 2 years.RESULTS: There were no significant differences in baseline characteristics between the two groups(P>0.05). At the last follow-up, the BCVA in the observation group was better than the control group(P<0.05). The intraocular pressure, CMT and progression of NVA in the observation group were less than the control group(all P<0.05). The patients with NVG developed from stage II to stage III in the observation group was less than the control group(P<0.05). In the observation group, the BCVA improved compared with preoperative at 6 mo(P<0.05). In the control group, the BCVA decreased compared with preoperative after 24 mo(P<0.05). Multiple linear regression analysis indicated that NVG progression and intraocular pressure were factors affecting BCVA(LogMAR)changes(β=0.511, 0.014; t=4.461, 2.092; P<0.01, 0.041, respectively). In the observation group, the IOP decreased at 1, 6 and 12 mo compared with preoperative(all P<0.05), while there were no significant differences at 18 and 24 mo compared with preoperative(all P>0.05). In the control group, the intraocular pressure decreased at 6 mo compared with preoperative(P<0.05), while there were no significant differences at 1, 12, 18 and 24 mo compared with preoperative(all P>0.05). There were no significant difference about the types of glaucoma drugs between the observation group and the control group(all P>0.05). There were no infectious endophthalmitis and other complications observed in both groups.CONCLUSION: IVC combined with PRP demonstrates superior efficacy over PRP monotherapy in treating NVG(stage II)secondary to PDR. IVC combined with PRP showed better outcomes in controlling iris neovascularization, slowing visual impairment progression, reducing intraocular pressure, and delaying disease advancement.

Objective To observe the clinical efficacy of acupuncture combined with Fire Dragon Cupping Therapy in the treatment of chronic non-specific low back pain(CNLBP)based on the bowstring mechanics theory.Methods A total of 80 patients diagnosed with CNLBP and admitted to the Acupuncture Department of Shenzhen Pingle Orthopedic and Traumatology Hospital(Shenzhen Pingshan District Hospital of Traditional Chinese Medicine)from January 2024 to December 2024 were selected as the study subjects.The patients were randomly divided into an observation group and a control group using a random number table,with 40 cases in each group.The control group received conventional acupuncture treatment,while the observation group received Fire Dragon Cupping Therapy in addition to the same acupuncture treatment as the control group.The treatment lasted for 2 weeks,with a follow-up conducted 3 months after treatment.After 2 weeks of treatment,the clinical efficacy of both groups was evaluated.Changes in the Visual Analogue Scale(VAS)score,modified Oswestry Disability Index(ODI)score,serum interleukin 6(IL-6)and tumor necrosis factor α(TNF-α)levels were observed before and after treatment.Additionally,changes in lumbar flexion,extension,lateral flexion,and rotation range of motion(ROM),as well as endurance time of lumbar flexor and extensor muscles,were compared between the two groups.Results(1)The total effective rate was 97.50％(39/40)in the observation group and 82.50％(33/40)in the control group.The efficacy of the observation group was superior to that of the control group,the difference being statistically significant(P＜0.05).(2)After treatment and at the 3-month follow-up,both groups showed significant improvements in VAS and ODI scores(P＜0.05),with the observation group demonstrating significantly better improvements than the control group,the differences being statistically significant(P＜0.05).(3)After treatment and at the 3-month follow-up,serum IL-6 and TNF-α levels significantly decreased in both groups(P＜0.05),with the observation group showing significantly greater reductions than the control group,the differences being statistically significant(P＜0.05).(4)After treatment and at the 3-month follow-up,lumbar flexion,extension,lateral flexion,and rotation ROM significantly improved in both groups(P＜0.05),with the observation group exhibiting significantly better improvements than the control group,the difference being statistically significant(P＜0.05).(5)After treatment and at the 3-month follow-up,lumbar flexor and extensor muscle endurance time significantly improved in both groups(P＜0.05),with the observation group demonstrating significantly better improvements than the control group,the difference being statistically significant(P＜0.05).Conclusion The combination of acupuncture and Fire Dragon Cupping Therapy based on the bowstring mechanics theory can significantly alleviate pain,restore lumbar function,and promote functional recovery in patients with CNLBP,demonstrating notable clinical efficacy.

Objective To assess the exposure levels of heavy metals,including lead,arsenic,mercury,and cadmium,in the local population in Sichuan and Chongqing,China,to compare and analyze the differences in reference intervals(RIs)obtained from direct and indirect sampling methods,and to explore the interchangeability and limitations of these two sampling methods.Methods RIs were obtained by the direct sampling method and the indirect sampling method.In the direct sample method,the levels of blood arsenic,urinary cadmium,urinary mercury,and blood lead levels of 5562 healthy participants aged 22-50 years in Sichuan and Chongqing,China were measured by atomic absorption spectrometry and inductively coupled plasma-mass spectrometry.Using the human biomonitoring(HBM)data,we established RIs for the population by a nonparametric method.On the other hand,in the indirect sampling method,RIs were established via a nonparametric method based on data from the laboratory information system(LIS)of a local hospital after stratifying healthy individuals using a Gaussian mixture model(GMM).Comparative analysis of the RIs derived from the two sampling methods were then conducted.Results The RI for blood arsenic was 0.11-1.3 μmol/L.The RI for urinary cadmium was 0.51-2.80 μmol/mol creatine for adults aged 22 to under 43 years and 0.66-2.96 μmol/mol creatine for adults aged 43-50 years.The RI for urinary mercury was 0.12-1.10 μmol/mol creatine.The RI for blood lead was 14.00-47.00 pg/L for adults aged 22 to under 41 year,16.00-53.38 pg/L for males aged 41-50 year,and 15.00-51.02 pg/L for females aged 41-50 year.Most of the RIs established by the direct sampling method had a narrower range compared to those established by the indirect sampling method,and the RIs established by both sampling methods were partially biased.Conclusions The RIs for blood arsenic,urine cadmium,urine mercury,and blood lead in healthy individuals aged 22-50 years in Sichuan and Chongqing,China were established using both direct and indirect sampling methods,which contributes to a better understanding of environmental exposure to metals in the general population and provides a reference for metal poisoning.For data from the same lab,the GMM-based indirect sampling method demonstrated relatively consistent performance in establishing RIs compared with the direct sampling method.
