Objective:To understand the prevalence and related factors of three common chronic diseases, hyperlipidemia, hypertension and diabetes in HIV-infected persons.Methods:As of December 2023, HIV-infected persons >15 years old who are receiving antiviral therapy (ART) and follow-up in Henan Province were selected as the study objects. Questionnaires, physical examinations, and blood samples were collected to collect demographic information, ART, body weight, blood lipids, blood pressure, and blood sugar of HIV-infected persons. The logistic regression model was used to analyze the related factors of hyperlipidemia, hypertension and diabetes.Results:Among 4 023 HIV-infected patients, the prevalence rates of hyperlipidemia, hypertension, and diabetes were 64.47% (2 594/4 023), 16.80% (676/4 023), and 10.54% (424/4 023), respectively. Multivariate analysis showed that hyperlipidemia was positively associated with ≥40 years of age, overweight and obesity, two nucleoside reverse transcriptase inhibitors (NRTIs) + proteasome inhibitors (PIs) regimen and two NRTIs+ integrase inhibitor regimen, and negatively associated with low body weight. Hypertension was positively correlated with the age group ≥40 years old, family history of cardiovascular and cerebrovascular diseases, overweight and obesity, ART time ≥0.5 years, and negatively correlated with low body weight. Diabetes was positively associated with age group ≥40 years, family history of cardiovascular and cerebrovascular disease, overweight and obesity, and negatively associated with the use of two NRTIs+PIs treatment regimens.Conclusions:In 2023, the prevalence of hyperlipidemia, hypertension, and diabetes among HIV-infected people in Henan Province was relatively high, and the risk of common chronic diseases among those ≥40 years old, overweight and obese, and those with a family history of cardiovascular and cerebrovascular diseases was also relatively high. It is recommended to strengthen the prevention and management of common chronic diseases among HIV-infected people.

Objective:To analyze the drug resistance characteristics and influencing factors in human immunodeficiency virus (HIV)-1 treated patients in Henan Province.Methods:HIV-1 treated patients who had received anti-retroviral therapy (ART) for more than six months and had a viral load >200 copies/mL in the Zhengzhou Sixth People′s Hospital from January to December 2024 were enrolled. Plasma samples were collected. Partial pol region gene sequences and integrase gene sequences of HIV-1 were amplified by reverse transcription nested polymerase chain reaction. The REGA HIV-1 subtype analysis tool was used to determine the subtypes of HIV-1 isolates, and the HIV drug resistance database of Stanford University in the United States was used to analyze the genetic drug resistance mutations and antiviral drug susceptibility. The multivariate logistic regression analysis was used to analyze the factors related to drug resistance. Results:Among 933 HIV-1 treated patients with ART failure, 825 samples were successfully amplified, with the amplification success rate of 88.42%. The overall drug resistance rate was 70.06%(578/825), among which the drug resistance rates of nucleoside reverse transcriptase inhibitor (NRTI), non-nucleoside reverse transcriptase inhibitor (NNRTI), protease inhibitor (PI), and integrase inhibitor (INSTI) were 55.15%(455/825), 64.36%(531/825), 5.70%(47/825), and 2.31%(19/821), respectively. The most common drug resistance mutations included M184I/V (47.88%(395/825)), K103N/S (38.18%(315/825)), and K70E/G/N/Q/R/S/T/del (16.61%(137/825)). Multivariate analysis showed that the baseline CD4 + T cell count <200 cells/μL (adjusted odds ratio ( OR)=2.239, 95% confidence interval ( CI)1.011 to 4.960), an initial 2NRTI+ NNRTI-based treatment regimen (adjusted OR=44.332, 95% CI 5.191 to 378.593), initial 2NRTI+ PI/r (r means ritonavir)-based regimen (adjusted OR=14.391, 95% CI 1.304 to 158.805) and a change in the ART regimen (adjusted OR=5.941, 95% CI 2.373 to 14.878) were independent risk factors for drug resistance (all P<0.05). Conclusions:The drug resistance rate after virological failure in HIV-1 treated patients in Henan Province is relatively high, which is mainly characterized by NNRTI resistance. The baseline immune status and the choice of the initial treatment regimen are important factors affecting the occurrence of drug resistance. The treatment monitoring and drug resistance monitoring should be strengthened.

Objective:To analyze the influencing factors of genotypic drug resistance mutations in people living with human immunodeficiency virus and acquired immunodeficiency syndrome(PLWHA) who failed anti-retroviral therapy (ART) in Henan Province, in order to provide a basis for adjusting ART regimens and reducing drug resistance.Methods:PLWHA with virological failure (human immunodeficiency virus (HIV) RNA≥500 copies/mL) after receiving ART for more than 24 weeks were included in Henan Province from January 2018 to December 2022. Baseline CD4 + T lymphocyte counts, ART regimens and other clinical data were collected. HIV-1 gene subtypes and their drug resistance sequence mutations were detected in the Sixth People′s Hospital of Zhengzhou, and the sequences were submitted to the HIV Drug Resistance Interpretation System of Stanford University for comparison of test results. Genotypic drug resistance to nucleotide reverse transcriptase inhibitors (NRTI), non-nucleoside reverse transcriptase inhibitors (NNRTI), protease inhibitors (PI) and integrase inhibitors (INSTI) was determined. Multivariate logistic regression was used to analyze the influencing factors of drug resistance in patients with ART failure. Results:Among 982 PLWHA, the sequences of 899 cases were successfully amplified, and drug resistance was detected in 737 cases, with the drug resistance rate of 81.98%(737/899). The rates of resistance to NRTIs, NNRTIs, PIs and INSTIs were 71.97%(647/899), 79.31%(713/899), 5.23%(47/899) and 2.72%(20/734), respectively.The largest number of those who developed concomitant resistance to two classes of drugs was 588 cases (79.78%), mainly NRTI and NNRTI concomitant resistance in 583 cases (79.10%). There were 99 cases (13.43%) who developed resistance to only one class of drugs, and those who developed concurrent resistance to three classes of drugs were 48 cases (6.51%), and two cases (0.27%) were found to be resistant to all four classes of drugs mentioned above. A total of 10 HIV genotypes were detected, among which subtype B accounted for the most (59.73%(537/899)), followed by circulating recombinant form (CRF)01_AE subtype (21.91%(197/899)) and CRF07_BC subtype (9.45%(85/899)). The risk factors affecting the development of drug resistance were baseline CD4 + T lymphocyte counts, ART regimens and HIV-1 genotypes. The risk of drug resistance in patients with baseline CD4 + T lymphocyte counts <100/μL was 4.55 times (95% confidence interval ( CI) 2.69 to 7.70) higher than patients with CD4 + T lymphocyte counts≥250/μL, the risk of drug resistance in patients using 2NRTIs+ NNRTI regimen was 4.51 times (95% CI 1.75 to 11.63) higer than those using 2NRTIs+ INSTI regimen, and patients infected with B and CRF01_AE subtype was 2.18 times (95% CI 1.10 to 4.29) and 2.70 times (95% CI 1.26 to 5.78) higer than those with CRF07_BC subtype, respectively. Conclusions:The incidence of genotypic drug resistance in PLWHA with ART failure in Henan Province is high. Low baseline CD4 + T lymphocyte counts, 2NRTIs+ NNRTI regimens, and genotype B and CRF01_AE are risk factors for drug resistance in PLWHA.

Objective:To investigate the value of intratumoral and peritumoral radiomics features of multi-parameter MRI in evaluation of the status of human epithelial growth factor receptor 2 in breast cancer.Methods:The clinical, pathological and imaging data of 340 patients with pathologically confirmed breast cancer in Henan Provincial People′s Hospital from September 2019 to December 2020 were retrospectively collected. All patients were female, 48 (42, 55) years old. All patients underwent multi-parameter breast MRI before surgery, including dynamic contrast-enhanced T 1WI (DCE-T 1WI), fat-suppressed T 2WI (T 2WI) and diffusion-weighted imaging (DWI). The region of interest (ROI) for lesions were manually delineated and the segmented ROIs were zoomed in ring shape by 4 mm to acquire ROI intra and ROI prei, respectively. Then six sets of radiomics features were extracted from ROI intra and ROI prei of DCE-T 1WI, T 2WI and DWI. The cases were divided into a training set (272 cases) and a test set (68 cases) by stratified sampling at a ratio of 4∶1. The Mann-Whitney U test, Select K Best and minimum absolute contraction and selection operator were used for feature selection of the 6 sets of radiomics features. The feature subsets after reduction were used to construct independent and combined radiomics signatures with support vector machine algorithm to predict the HER2 status of breast cancer. Receiver operating characteristic curve was generated and area under curve (AUC) was calculated to compare the prediction performance of different models. Results:Of the 340 patients, 80 were HER2-positive and 260 were HER2-negative. Among the radiomics signatures based on single sequence, the DWI peri showed the best performance in predicting HER2 status of breast cancer, with an AUC of 0.678 for the test set. Among the combination of intratumoral and peritumoral radiomics signatures based on same sequence, the DWI intra+DWI peri had the highest prediction value, achieving an AUC of 0.774 for the testing set. Among the intratumoral or peritumoral radiomics signatures derived from two different sequences, the DCE-T 1WI intra+DWI intra and T 2WI peri+DWI peri showed the best predictive performance, yielding AUC of 0.766 and 0.769 in the testing set, respectively. Among the combination of intratumoral or peritumoral radiomics signatures derived from all 3 sequences or combinations of all features, the DCE-T 1WI intra+T 2WI intra+DWI intra+DCE-T 1WI peri+T 2WI peri+DWI peri obtained the highest prediction efficiency, with an AUC of 0.913 for the testing set. Conclusion:The radiomics features of intratumoral and peritumoral regions based on multi-parameter MRI have a certain value in non-invasive evaluation of HER2 status of breast cancer, which can help clinicians to provide scientific basis for decision-making of targeted therapy in patients with breast cancer.

Objective:To analyze the drug resistance characteristics of HIV/AIDS patients in Henan Province with antiretroviral treatment (ART) failure through the genotypic drug resistance detection.Methods:Blood samples were collected from HIV/AIDS patients who received ART for more than 6 months with viral loads ≥1 000 copies/ml in 18 cities of Henan from January 2018 to May 2021. The genotypic drug resistance detection was conducted by using an In-house drug resistance detection method. The drug resistance mutation (DRM) and antiretroviral susceptibility were analyzed by submitting the determined sequences to the Stanford HIV-1 drug resistance database. The information about patients' demographic characteristics and antiviral treatment data were collected.Results:A total of 887 HIV/AIDS patients with ART failure, 812 sequences were successfully amplified with the success rate of 91.54%. In the 812 patients, 676 were drug resistant (83.25%, 676/812). The drug resistance ratesto nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), protease inhibitors (PIs), and integrase strand transfer inhibitors (INSTIs) were 73.40% (596/812), 80.54% (654/812), 5.54% (45/812), and 2.56% (17/663), respectively. There were significant differences in drug resistance rates among four types of drugs ( χ2=1 686.34, P<0.001). The drug resistance rate to two drugs was 66.38% (539/812), and the drug resistance rate to three drugs was 5.79% (47/812). A total of 9 subtypes of HIV-1were detected, in which subtype B accounted for 59.61%(484/812), followed by subtype CRF01_AE (22.17%, 180/812) and subtype CRF07_BC (9.48%, 77/812). There were significant differences in drug resistance rate among different subtypes ( χ2=21.33, P=0.001). Among NRTIs related mutation sites, the DRM rate of M184V/I was highest (63.42%, 515/812), followed by K65R (27.46%, 223/812). The top three DRM rates were detected for K103N/S (34.98%, 284/812), G190A/S (26.11%, 212/812) and V106M/I (24.63%, 200/812) among NNRTIs related mutation sites, and M46I (4.31%, 35/812), V82A/F (3.82%, 31/812), and I54V/MV (3.69%, 30/812) among PIs related mutation sites. While among INSTIs related mutation sites, E157Q/EQ had the highest DRM rate (3.47%, 23/663), followed by R263K (0.75%, 5/663) and G140A (0.75%, 5/663). The resistance to lamivudine and emtricitabine of NRTIs was at high-level (65.52%, 532/812), and the resistance to nevirapine (77.46%, 629/812) and efavirenz (71.18%, 578/812) of NNRTIs was also at high-level. The medium/high-level resistance to lopinavir/ritonavir of PIs was only 4.19% (34/812), the medium/high-level resistance to elvitegravir and raltegravir of INSTIs was 1.66% (11/663) and 1.21% (8/663), respectively, and no high-level resistance to bictegravir or dolutegravir was found. Conclusions:The drug resistance in HIV/AIDS patients with ART failure was high in Henan, characterized by high drug resistance rates to NRTIs and NNRTIs, and diverse and complex resistance mutations. So high resistance barrier ART-regimens were recommended, and the viral load monitoring and drug resistance testing after ART should be strengthened.

Objective:To investigate the drug resistance of patients with acquired immunodeficiency syndrome (AIDS) who failed antiviral therapy.Methods:A total of 156 AIDS patients with antiviral therapy failure at the Sixth People′s Hospital of Zhengzhou from October 2017 to December 2018 were selected. The human immunodeficiency virus (HIV)-1 ViroSeq? genotyping method was used for the detection of HIV resistance, and Stanford University HIV drug resistance database (http: ∥hivdb.stanford.edu/) was used for testing results comparison.Results:Among the 156 AIDS patients with antiviral therapy failure, 122(78.21%) developed drug resistance. One hundred and six (67.95%) cases were multi-resistant to nucleoside reverse transcriptase inhibitor (NRTI), among which, 104 (66.67%) were resistant to lamivudine, emtricitabine and abacavir. One hundred and eighteen (75.64%) were resistant to non-nucleoside reverse transcriptase inhibitor (NNRTI), and 118 (75.64%) were multi-resistant to efavirenz and nevirapine. And seven (4.49%) were resistant to protease inhibitor (PI). There were 16 resistant sites for NRTI, with 87 (71.31%) most frequent M184V/I mutations. There were 13 resistant sites for NNRTI, with 49 (40.16%) K103N/R mutations. There were 11 resistant sites for PI, with 49 (40.16%) A71V/T mutations. The antiviral drugs lamivudine and emtricitabine were moderately and highly resistant in 102 (83.61%) cases, efavirenz and nevirapine were moderately and highly resistant in 117 (95.90%) cases. Once drug resistance developed, these drugs were likely to be moderate or high resistance. There were 29 (23.77%), 48 (39.34%), and five (4.10%) cases were resistant to zidovudine, tenofovir and lopinavir/ritonavir, respectively. The resistance barrier of these drugs was relatively high.Conclusion:The incidence of drug resistance in patients with AIDS treatment failure is high, and multi-drug resistance is serious with various sites of drug resistance.

Pace of life and work of people is accelerating nowadays, and hospitals keep improving their services, which gives rise to the decoction and delivery service from the third party vendors for traditional Chinese medicine(TCM).Given the quality control standards for the TCM decoction service as issued by Zhejiang and other regions, the systems of supervision and assessment remain incomplete.Authors of the paper introduced a project improvement team, composed of Chinese medicine pharmacy, Chinese medicine experience specialists, vendors of Chinese medicine decoction and express delivery companies, hence establishing a " three-in-one" supervision system of Internet+TCM decoction and delivery service. This practice can optimize the assessment indexes, strengthen the assessment system of assessment transformation and supervision system for patient medication.It proves that the practice contributes to higher quality and safety of TCM decoction and delivery service, improves the ability and level of TCM services, and ensures the medication safety of patients.
