Objective: To analyze the trends in new diagnosis rates of HIV/AIDS cases in Huzhou City, Zhejiang Province from 2009 to 2023, so as to provide the basis for improving HIV/AIDS prevention and control strategies. Methods: Data of newly reported HIV/AIDS cases in Huzhou City from 2009 to 2023 were collected through the Chinese Disease Prevention and Control Information System. The new diagnosis rate was calculated as the ratio of newly reported HIV/AIDS cases within one year to the permanent resident population during the same period. The gender, age, and regional distribution characteristics of new diagnosis rates of HIV/AIDS cases were described. The trends were analyzed using average annual percent change (AAPC) and annual percent change (APC). Results: A total of 2 088 new HIV/AIDS cases were reported in Huzhou City from 2009 to 2023, with an average annual new diagnosis rate of 4.53/105. The new diagnosis rates showed an overall increasing trend from 2009 to 2023 (AAPC=12.745%, P<0.05), with rapid growth during 2009 to 2015 (APC=32.734%, P<0.05) but no significant trend during 2015 to 2023 (P>0.05). The average annual new diagnosis rate was significantly higher in males than in females (7.54/100 000 vs. 1.40/100 000, P<0.05). Male new diagnosis rate trend closely mirrored the overall population pattern, while females showed a continuous upward trend without clear inflection point (AAPC=12.575%, P<0.05). Age-specific analysis revealed average annual new diagnosis rates of 2.75/100 000, 6.16/100 000 and 3.83/100 000 for AIDS/HIV cases aged <25, 25-<50 and ≥50 years, respectively. The cases aged <25 years showed no significant trend (P>0.05), while the cases aged 25-<50 and ≥50 years followed patterns similar to the overall population. The average annual new diagnosis rates of HIV/AIDS cases in Wuxing District, Nanxun District, Deqing County, Changxing County and Anji County were 6.54/100 000, 3.43/100 000, 3.45/100 000, 3.56/100 000 and 4.94/100 000, respectively, showing overall upward trends (AAPC=9.672%, 27.599%, 11.800%, 18.896% and 10.254%, all P<0.05). Conclusions The new diagnosis rate of HIV/AIDS cases showed an overall upward trend in Huzhou City from 2009 to 2023. Cases are mainly concentrated among males, people aged 25-<50 years and Wuxing District, making them key targets for HIV/AIDS prevention and control.

OBJECTIVE: In order to enhance the efficacy of anti-breast cancer, paclitaxel nanoparticles (PTX NPs) and polypyrrole nanoparticles (PPy NPs) were combined with photothermal therapy and chemotherapy. At the same time, the two dosage forms of PTX NPs and PTX NPs gel were compared. METHODS: PTX NPs were prepared by self-assembly method, and then the cytotoxicity in vitro was investigated by Methyl thiazolyl tetrazolium (MTT) and other methods, and the efficacy and side effects in vivo were further investigated. RESULTS: The average hydrated diameter, PDI and electric potential of PTX NPs were (210.20 ± 1.57) nm, (0.081 ± 0.003) mV and (15.80 ± 0.35) mV, respectively. MTT results showed that the IC₅₀ value of PTX NPs on 4 T1 cells was 0.490 μg/mL, while that of PTX injection was 1.737 μg/mL. The cell inhibitory effect of PTX NPs was about 3.5 times higher than that of PTX injection. The tumor inhibition rates of PTX NPs and gel were 48.64% and 56.79%, respectively. Together with local photothermal stimulation, the tumor inhibition rate of the PTX NPs reached 91.05%, surpassing that of the gel under the same conditions (48.98%), moreover, the organ index and H&E staining results of PTX NPs showed a decrease in toxicity. CONCLUSION This combination therapy can significantly enhance the effect of anti-breast cancer, and the synergistic effect of chemotherapy and light and heat provides a feasible and effective strategy for the treatment of tumor.

ObjectiveTo analyze the characteristics of HIV-1 molecular network and pretreatment drug resistance genes in the middle-aged and elderly people aged ≥50 years in Huzhou City, Zhejiang Province, and to provide an evidence for the prevention and control of AIDS epidemic. MethodsA total of 332 samples from the newly reported and untreated AIDS patients aged ≥50 years in Huzhou City from January 2020 to December 2023 were collected, pol genes were amplified by reverse transcription polymerase chain reaction (RT-PCR) and nested polymerase chain reaction (nest⁃PCR). Phylogenetic trees analyzing the subtypes were constructed, and a molecular network with a gene distance threshold of 1.0% were constructed at the same time. Mutation sites of drug resistance-related genes were identified through the Data Analysis and Detection System of HIV-1 Resistance Gene Detection of Stanford University, USA. ResultsSequence samples of 308 patients were obtained, and9 genotypes were identified, including CRF07_BC in 172 cases (55.8%), CRF01_AE in 61 cases (19.8%), CRF08_BC in 43 cases (14.0%), CRF85_BC in 9 cases (2.9%), and CRF55_01B in 8 cases (2.6%), subtype B in 5 cases (1.6%), subtype C in 4 cases (1.3%), CRF67_01B in3 cases (1.0%), and unique recombination URF01_AE/07_BC in 3 cases (1.0%). When the gene distance threshold was 1.0%, 28 molecular clusters were formed, and 139 cases were connected to the network, with an access rate of 45.0%. The largest transmission cluster C1 contained 44 cases infected with CRF07_BC subtype, all of whom were heterosexually transmitted, and predominantly by males. A total of 30 patients were found to have low-grade or higher drug resistance mutations, and the pretreatment drug resistance rate was 9.7% (30/308). Among them, there were 5 cases (16.7%) of protease inhibitor (PI) related drug resistance mutations, and 26 cases (86.7%) of non-nucleoside reverse transcriptase inhibitors (NNRTI) related drug resistance mutations. ConclusionCRF07_BC is the subtype with the most clusters among the middle-aged and elderly infected patients aged ≥50 years in Huzhou City. Middle-aged and elderly transmission clusters are formed within the three counties of WX, NX and CX through related activities. Molecular network monitoring on newly reported cases aged ≥50 years in Huzhou City should be strengthened so that the new characteristics of epidemic changes can be detected in time, providing a scientific basis for adjusting AIDS prevention and control measures for the elderly.

ObjectiveTo analyze the surveillance status of acute respiratory tract infection pathogens in Fengxian District of Shanghai, and to determine the pathogen spectrum and epidemiological characteristics of acute respiratory tract infection in the district. MethodsCase surveillance data from Fengxian Central Hospital were collected through the Shanghai Integrated Surveillance System for Acute Respiratory Infections, and respiratory specimens were collected from the 50^th week of 2022 to the 49^th week of 2023 for nucleic acid detection of 25 pathogens and bacterial culture testing. Case surveillance data from Fengxian Central Hospital were collected through the National Influenza Sentinel Surveillance System, and respiratory specimens were collected for nucleic acid detection of 5 pathogens. ResultsThe percentage seeking for medical visits of influenza-like illness (ILI) and severe acute respiratory infection (SARI) were 4.74% and 0.81%, respectively, with epidemic peaks in winter and spring. A total of 1 610 samples were detected, among which 354 were SARI cases, whose age of P₂₅ and P₇₅ quartiles were 44 years and 71 years, respectively, with a positive detection rate of 48.31%. Among the 1 256 ILI cases, the age of P₂₅ and P₇₅ quartiles were 21 years and 39 years, respectively. The positive detection rate of pathogens was 65.04% in 123 ILI cases under comprehensive surveillance of respiratory tract infection and 66.11% in 1 133 ILI cases under influenza surveillance. The positive rates of influenza andSARS-CoV-2 in SARI samples were 12.99% and 29.66%, respectively. The positive rates of influenza and SARS-CoV-2 in ILI case samples were 33.20% and 31.53%, respectively. Influenza virus concentrated in the winter and spring. The ILI and SARI cases had the highest positivity rates in the 6‒14 years old group and 15‒24 years old group, respectively. ConclusionThe main pathogens of respiratory tract infection in Fengxian District of Shanghai were SARS-CoV-2 and influenza virus. Special efforts should be made to monitor respiratory disease pathogens in the population under 24 years old, and surveillance of SARI cases aged ≥60 years should be strengthened. The influenza virus and SARS-CoV-2 are alternating, which is different from the past and requires a change in the previous prevention and control strategies.
