Gouty arthritis (GA) is an inflammatory disorder caused by monosodium urate (MSU) crystal deposition, accompanied by elevated oxidative stress and aberrant release of inflammatory cytokines, resulting in joint tissue damage and intense pain. Nuclear factor E2-related factor 2 (Nrf2), a key transcription factor regulating the antioxidant defence system, exerts cytoprotective effects through dissociation from Kelch-like ECH-associated protein 1 (Keap1) and activates downstream antioxidant response element (ARE)-mediated pathways. It can upregulate the expression of heme oxygenase-1 (HO-1), NADH quinone oxidoreductase 1 (NQO1), superoxide dismutase (SOD), and glutathione transferase (GST) to preserve redox homeostasis. Moreover, Nrf2 can suppress activation of NOD-like receptor protein 3 (NLRP3) inflammasomes, reduce pro-inflammatory cytokine production and release, modulate nuclear factor-κB (NF-κB) transcriptional activity, regulate gut microbiota balance, enhance mitophagy, and inhibit apoptosis, so as to reduce joint inflammation and pain and promote body recovery. This review systematically examined recent advancements in traditional Chinese medicine (TCM) for GA prevention and treatment via regulating the Nrf2 signaling pathway. It delineated Nrf2's molecular mechanisms and its role in GA pathogenesis and elucidated how TCM intervenes in multiple pathways including Keap1/Nrf2/ARE, Nrf2/HO-1(NQO1), and Nrf2/NF-κB/NLRP3 to exert therapeutic effects. The study demonstrated that TCM monomers and compounds effectively counteract oxidative damage, attenuate inflammatory responses, promote autophagy, and inhibit apoptosis via regulating the Nrf2 signaling pathway. These findings not only clarify the scientific basis of TCM in GA treatment but also offer strategic insights for developing novel Nrf2-targeted anti-gout drugs.

ObjectiveTo genotype Oncomelania hupensis, based on microsatellites, in different snail-bearing environments in Jiaxing City, Zhejiang Province, for population genetics analysis in order to explore the reasons and influencing factors for the existence or proliferation of snails and to provide scientific basis for effective monitoring and control of snails. MethodsA total of 90 snail samples from three populations were collected in Yaobang Village (YB) and Sanxing Village (SX) in Pinghu City, and Yunhe Farm (YH) in Xiuzhou District, all were selected for snail checking in key snail habitats of Jiaxing City in 2022. DNA of the snails was genotyped and analyzed for population genetics using nine microsatellite loci. ResultsA total of 84 alleles were observed, and the mean number of alleles (Na) was 7.889, 5.667, and 3.778 for YB, SX, and YH respectively; the number of effective alleles (NeA) was 4.807, 3.329, and 2.294, respectively; and the coefficients of inbreeding (FIS) were 0.400, 0.377, and 0.493, respectively. Under the Infinite Allele Model (IAM), the SX and YH might have a recent bottleneck. The NEstimator and LDNe software calculated effective population sizes (Ne) were above 31.9. AMOVA analysis showed that the variation of snails in the three populations mainly existed among individuals, accounting for 41.4% of the total variation. The value of the index of genetic differentiation between populations (FST) was 0.286, indicating a high degree of genetic differentiation. The results of the principal component analysis and phylogenetic tree were consistent, and the three populations were divided into two lineages, YB and SX were one lineage, and YH belonged to another independent lineage. Population history and dynamics analysis showed that the gene flow of the three populations was insufficient, population divergence history indicated that YH might have diverged from SX first, and YB was produced by the contact fusion of SX and YH. ConclusionThe genetic diversity of snail populations in Jiaxing City is generally low, and the snail populations are unstable, with a great degree of genetic differentiation and insufficient gene flow among populations. This study can provide a basis for evaluating the effectiveness of the control of the snail as well as monitoring the trend of the spread of the snail.

Extremely unbalanced data here refers to datasets where the values of independent or dependent variables exhibit severe unbalance in proportions, such as extremely unbalanced case-control ratio, very low incidence rate of disease, heavily censored time-to-event data, and low-frequency or rare variants. In such scenarios, the statistic derived from hypothesis test using the classical statistical method, e.g., logistic regression model and Cox proportional hazard regression model, might deviate from theoretical asymptotic distribution, resulting in inflation or deflation of type I error. With the increased availability and exploration of resources from large-scale population cohorts in genome-wide association study (GWAS), there is a growing demand for effective and accurate statistical approaches to handle extremely unbalanced data in independent and non-independent samples. Our study introduces classical statistical methods in genetic statistics firstly, then, summarizes the failure of classical statistical methods in dealing with extremely unbalanced data through simulation experiments to draw researchers' attention to the extremely unbalanced data in GWAS.

ObjectiveTo evaluate the efficacy and safety of topical Bisaitong (鼻塞通) in treating moderate-to-severe allergic rhinitis (AR). MethodsA randomized, positive-controlled, non-inferiority clinical trial design was adopted. Totally, 108 cases of moderate-to-severe AR were randomly divided into Bisaitong group and mometasone furoate group,with 54 cases in each group. The Bisaitong group was treated with Bisaitong smeared at the nasal cavity twice a day, and the mometasone furoate group received inhalation of mometasone furoate nasal spray 100 μg in each nostril, once a day. Both groups were treated for 4 weeks and followed up after additional 4 weeks. Both groups were compared on the rhinoconjunctivitis quality of life questionnaire (RQLQ), rhinoconjunctivitis total symptom score (RTSS), visual analogue score (VAS) of sneezing, runny nose, nasal itching, nasal congestion degree, days of AR episodes at enrollment, after 2- and 4-week, and at follow-up. The peripheral blood eosinophil (EOS) count and percentage (EOS%), serum eosinophil cationic protein (ECP), serum dust mite, dermatophagoides farinae, and cockroach allergen-specific IgE (sIgE) levels were compared between groups at enrollment and after 4-week treatment. Drug overuse rate was calculated, and the safety was evaluated. The analysis of all efficacy outcomes was based on both full analysis set (FAS) and per-protocol set (PPS). ResultsThe lower limit of the 95% confidence interval for the differences in RQLQ scores were greater than -0.6 measured after 2- and 4-week treatment and at follow-up compared to that measured at the enrollment in both groups, indicating of the Bisaitong group being non-inferior to the mometasone furoate group. There was no statistically significant difference between groups on RTSS score, VAS scores of sneezing, runny nose, nasal itching, nasal congestion degree and days of episodes at all timepoints (P>0.05), but each outcome changed significantly over time in both groups (P<0.01). The differences between groups in EOS count, EOS%, ECP levels, serum dust mite, dermatophagoides farinae, cockroach sIgE levels, and drug overuse rate were not statistically significant at enrollment and after 4-week treatment (P>0.05). Adverse events occurred in eight cases (15.10%) in the Bisaitong group and five cases (9.30%) in the mometasone furoate group, showing no significant difference between groups (P>0.05). ConclusionTopical Bisaitong is non-inferior to mometasone furoate nasal spray in the treatment of moderate to severe AR in terms of clinical symptom relief,reduction in the episodes, improvement of quality of life, and sound safety.

BACKGROUND:
LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer.
METHODS:
We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels.
RESULTS:
On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]).
CONCLUSION:
LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile.

Objective:
To perform an epidemiological survey of the first case with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Pinghu City of Jiaxing City, Zhejiang Province on March 13, 2022, so as to provide insights into the management of coronavirus disease (COVID-19) epidemics.
Methods:
According to the requirements of the Protocol on Prevention and Control of COVID-19 (8th Edition), epidemiological investigations were performed among 39 cases with SARS-CoV-2 infections in Pinghu City from March 13 to 20, 2022. Cases' demographics, clinical symptoms, history of immunization and exposure were collected, and close contacts were identified. Pharyngeal swabs were sampled from infected cases for detection of SARS-CoV-2 nucleic acid and whole-genome sequencing, and the source of infection and transmission route were investigated.
Results:
The index case for this COVID-19 epidemic was an imported case from Shanghai Municipality, who infected 6 persons via aerosol transmission when playing in the badminton venue of Pinghu National Fitness Center on March 9; subsequently, one of these infected cases infected another 18 persons when playing in the badminton venue of Jiadian Village Resident's Fitness Center in Zhapu Township on March 12. Sixteen confirmed cases were reported, and all cases were mild; another 23 asymptomatic cases were diagnosed, with no death reported. This epidemic occurred from March 11 to 20, with 3 generations of spread and a median incubation period of 3 days. The SARS-CoV-2 infected cases had a median age of 33.5 (interquartile range, 12.0) years and included 36 cases with a history of COVID-19 vaccination. There were 16 cases with fever, cough, runny nose and sore throat, and 13 cases with imaging features of pneumonia. The effective reproductive number (Rt) of the COVID-19 epidemic was 7.73 at early stage, and was less than 1 since March 21. Whole-genome sequencing identified Omicron BA.2 variant among 33 cases, which had high homology with the index cases.
Conclusion
This epidemic was a cluster of COVID-19 caused by imported Omicron BA.2 variant infection from Shanghai Municipality, and the COVID-19 transmission was mainly caused by indoor aerosols.

Objective:
To understand epidemiology and associated factors of delay for tuberculosis in schools of Jiaxing, and to provide basis for the strategy of pulmonary tuberculosis prevention and control in schools.
Methods:
Based on the Tuberculosis Management Information System, the information of school tuberculosis cases in Jiaxing from 2011 to 2020 was collected, and the epidemiological characteristics were analyzed by descriptive epidemiology.
Results:
A total of 436 student pulmonary tuberculosis patients and 46 teacher pulmonary tuberculosis patients were reported in Jiaxing from 2011 to 2020. The average annual incidence rate in teachers (10.70/100 000) was higher than that in students (6.16/100 000) ( χ 2=13.06, P <0.05). The incidence rate of school pulmonary tuberculosis (6.59/100 000) was lower than that in the whole population (37.91/100 000) ( χ 2=184.63, P < 0.05 ). The school pulmonary tuberculosis patients mainly occurred from March to May, accounted for 11.62%,11.00%,9.96% respectively. The incidence rate of school pulmonary tuberculosis patients in county level was lower than in urban district in 2012, and higher than in urban district in 2017 and 2020( χ 2=4.61,5.72,4.02, P <0.05). Most student pulmonary tuberculosis patients aged from 15 to 19 years old, the percentage was higher in males(90) than in females(75) in students. The reported incidence rate of pulmonary tuberculosis in primary school and junior high school teachers was higher than that in the same students ( χ 2=24.34, 14.87 , P <0.05). Passive case finding including clinical symptomatic inspection and referrals was the main way to find cases. The detection delay rate was 34.23%.
Conclusion
Early detection, prompt and scientific treatment, shortening the delay time were key to prevent the spread of the school tuberculosis. It is of great significance to reduce the occurrence of clustering in outbreak and public health emergency.

Objective:To analyze the relationship between infection and transmission of HIV/AIDS, explore the characteristics of the HIV-1 transmission network, and provide evidence for formulating targeted prevention and control measures.Methods:The newly confirmed HIV/AIDS in Jiaxing from 2017 to 2018 were selected for the study. The sociodemographic and infection transmission-related information was gathered. The blood samples were collected and RNA was extracted, RT-PCR and nested PCR amplified the pol gene of HIV-1. The phylogenetic tree was constructed by Mega 6.0 software for subtype analysis. The genetic distance between strains was calculated, and the molecular transmission network was drawn by using Cytoscape 3.6.0 software. The results of the epidemiological study based on the molecular transmission network were analyzed. Results:There were fifteen HIV-1 gene subtypes in 517 cases of HIV/AIDS. The main subtypes were CRF01_AE (37.1%)、CRF07_BC (36.2%) and CRF08_BC (11.8%). Under the 1.0% gene distance threshold, 87 molecular clusters were established, and the total clustering rate was 45.8% (237/517). The cluster risk factors were 60-81 age group (compared with 14-24 age group, OR=2.690, 95% CI:1.058-6.844), married (compared with unmarried, OR=1.698, 95% CI:1.003-2.875), CRF07_BC subtype (compared with CRF01_AE, OR=2.203, 95% CI:1.426-3.404). The largest molecular cluster, CRF07_BC-1, consisted of 50 cases (including 21 cases confirmed in 2017 cases and 29 confirmed in 2018). Multivariate analysis showed that characteristics of unmarried (compared with married, OR=2.482, 95% CI:1.140-5.402), gays (compared with heterosexual, OR=3.163, 95% CI:1.543-6.483), cases with high-risk transmission (compared with other cases, OR=7.631, 95% CI:1.783-32.654), confirmed in Nanhu and Pinghu districts of Jiaxing (compared with other districts, OR=2.225, 95% CI:1.074-4.608) were risks for entering the largest molecular cluster. There were seven suspected high-risk transmission MSM in the largest molecular cluster. The first debut of homosexual behavior was from 2010 to 2018, and the median number of gay partners was 20 ( P 25, P 75:10, 100) within two years before being diagnosed. Six reported a recent history of looking for gay partners in an MSM dating place in Nanhu district. Conclusions:The HIV-1 subtypes of newly confirmed HIV/AIDS were diverse, mainly sporadic in Jiaxing from 2017 to 2018. There were geographical aggregation characteristics and suspected some high-risk transmission cases, suggesting that rapid transmission and targeted intensive intervention are needed.
