Background and aims:Clinical data regarding patients with chronic hepatitis B(CHB)after Omicron BA.5 infection are currently limited.This study aimed to assess the clinical characteristics of patients with CHB and Omicron BA.5 infection in South China.Methods:This retrospective study was conducted from January to March 2023 in a cohort of 485 healthy individuals and 553 patients with CHB.Clinical features,encompassing COVID-19-related symptoms,levels of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)antibodies,vaccination status,liver functions,and virological markers of hepatitis B virus(HBV)infection were measured.Results:COVID-19-related symptom patterns were similar in both groups,except for fever,which was notably less prevalent(85.4％vs.90.4％,P=0.047)among patients with CHB who experienced a significantly shorter duration of fever(median 2.2(25th-75th percentile,1.0-3.0)days vs.2.3(1.0-3.0)days,P=0.048)and a shorter time for symptom relief(9.2(5.0-14.0)vs.11.1(5.0-14.0)days,P=0.015).The levels of SARS-CoV-2 antibodies were comparable between the two groups but increased after booster vaccinations.In patients with CHB,globulin(GLB)and hepatitis B envelope antibody levels were significantly increased after Omicron BA.5 infection,regardless of nucleos(t)ide analog regimens comparing entecavir(ETV)with tenofovir(TFV).Patients with CHB treated with TFV had significantly higher levels of SARS-CoV-2 antibodies than those treated with ETV(1065.1(346.9-1188.5)COI vs.765.5(24.5-1119.1)COI,P=0.025).Conclusions:No significant exacerbation of COVID-19 symptoms was observed in conjunction with the efficacy of COVID-19 booster vaccinations.There were no notable alterations in liver functions except for GLB.HBV reactivation,as evidenced by increased HBV DNA,was observed among patients with CHB after Omicron BA.5 infection.These changes were not affected by ETV versus TFV administration;however,TFV resulted in a significant increase in SARS-CoV-2 antibody levels.Further studies are required to improve care and therapeutics for patients with CHB who contracted COVID-19.

Objective To observe the levels of serum NOD-like receptor thermal protein domain associated protein 3(NLRP3),cysteine protease 1(Caspase-1),and interleukin 1β(IL-1β)in patients with systemic lupus erythematosus(SLE)and to explore their correlation with traditional Chinese medicine(TCM)syndrome types,thus to assess the significance of NLRP3,Caspase-1 and IL-1β in TCM syndrome differentiation.Methods A total of 110 cases of SLE patients who met the inclusion criteria and 30 cases of healthy physical examinee from Linhai Hospital of Traditional Chinese Medicine during October 2020 to March 2024 were enrolled into the study.The serum NLRP3,Caspase-1,IL-1β levels of the two groups were compared,and the correlation between serum NLRP3,Caspase-1,IL-1β levels and the Systemic Lupus Erythematosus Disease Activity Index(SLEDAI)scores was analyzed.Moreover,the distribution of the TCM syndrome types in 110 cases of SLE patients was investigated and then the correlation between TCM syndrome types and serum NLRP3,Caspase-1,and IL-1β levels in SLE patients was explored.Results(1)The serum NLRP3 and Caspase-1 levels of patients in SLE group were lower than those of healthy control group,and the serum IL-1β level was higher than that of healthy control group,and the differences were statistically significant(P<0.05).Spearman's correlation analysis showed that the SLEDAI score was negatively correlated with both of NLRP3 and Caspase-1(r=-0.854,-0.599,P<0.01),and SLEDAI score was positively correlated with IL-1β(r=0.584,P<0.01).(2)The TCM syndrome types in 110 cases of SLE patients ranking in descending order were as follows:excessive heat toxin syndrome(33.64%)>yang deficiency of spleen and kidney syndrome(25.45%)>internal heat due to yin deficiency syndrome(24.55%)>yin deficiency of liver and kidney syndrome(16.36%).(3)The serum NLRP3 and Caspase-1 levels were in ascending order while the serum IL-1β level was in descending order in SLE patients with the TCM syndrome types of excessive heat toxin syndrome,internal heat due to yin deficiency syndrome,yang deficiency of spleen and kidney syndrome,yin deficiency of liver and kidney syndrome,respectively.And the differences were all statistically significant(P<0.05).(4)The results of multivariate logistic regression analysis showed that serum NLRP3 and caspase-1 levels were negatively correlated with syndromes of yin deficiency of liver and kidney,yang deficiency of spleen and kidney,internal heat due to yin deficiency,and excessive heat toxin(P<0.05 or P<0.01),while serum IL-1β level was positively correlated with the above syndromes(P<0.05).Conclusion Serum NLRP3 and Caspase-1 levels in SLE patients are negatively correlated with the disease activity,and serum IL-1β level is positively correlated with the disease activity.There is a certain correlation between TCM syndrome types and NLRP3,Caspase-1 and IL-1β levels in SLE patients,indicating that NLRP3,Caspase-1 and IL-1β may be the potential biological indicators for TCM syndrome differentiation of SLE.

Objective To analyze the clinical efficacy of low temperature plasma radiofrequency ablation(RFA)combined with nasal irrigation in the treatment of allergic rhinitis(AR)with nasal septal deviation.Methods A total of 120 AR patients with nasal septal deviation who were diagnosed and treated in Taikang Xianlin Drum Tower Hospital from August 2018 to December 2022 were selected as research objects.They were assigned to observation group or control group according to random number table method,with 60 cases in each group.The control group received nasal irrigation,and the observation group received low temperature plasma RFA and nasal irrigation.The efficacy,immunity,inflammation,quality of life,safety and prognosis were compared between the two groups.Results The observation group had better curative effect than the control group(P<0.05).The natural killer(NK)cells were increased,and the levels of immunoglobulin G(IgE),thymic stromal lymphopoietin(TSLP),hypoxia-inducible factor-1(HIF-1)and fractional exhaled nitric oxide(FeNO)were decreased in both groups after treatment.The level of NK cells in the observation group was higher than that in the control group after treatment,and the levels of IgE,TSLP,HIF-1,and FeNO in the observation group were lower than those in the control group(P<0.05).After treatment,the rhinoconjunctivitis quality of life questionnaire(RQLQ)scores decreased in both groups,and the scores in the observation group were lower than those in the control group(P<0.05).There was no significant difference in safety between the two groups(P>0.05).The control group had higher recurrence rate than the observation group(P<0.05).Conclusion Low temperature plasma RFA combined with nasal irrigation can effectively improve the immune function and inflammation of AR patients with nasal septal deviation,thereby improving the efficacy and quality of life,and reducing the recurrence rate,with high safety.

Objective: To understand the prevalence and related factors of depressive symptoms among primary and secondary school students in the in depth monitoring counties of China s Rural Compulsory Education Nutrition Improvement Program, so as to provide a basis for prevention and psychological intervention of depressive symptoms among children and adolescents in rural areas. Methods: In November 2022, a stratified random sampling method was adopted to collect height and weight data, basic personal and family information of 7 949 primary and secondary school students from grade three to grade nine through physical measurements and questionnaires in 56 key monitoring schools implementing the Student Nutrition Improvement Program in 7 in depth monitoring counties (Jalaid Banner in Inner Mongolia, Jinzhai County in Anhui, Mao Xian in Sichuan, Tiandeng County in Guangxi, Mian County in Shaanxi, Zhaozhou County in Heilongjiang and Youxi County in Fujian), and to obtain the information related to their depressive symptoms through the self assessment questionnaire on depression. Multivariate Logistic regression analysis was conducted to analyze the prevalence of depressive symptoms among primary and secondary school students, as well as their related factors. Results: The detection rate of depressive symptoms among primary and secondary school students in the in depth monitored counties was 23.5%. Logistic regression analysis showed that the probability of detecting depressive symptoms was higher among female students, middle school students, students whose video screen duration per day was >2 h, and students whose parents marital status was divorced or widowed ( OR =1.40, 1.64, 1.60, 1.24), and students whose sleep duration reached the recommended standard, whose parents usually accompanied them daily for time was 60-<120 min and ≥120 min, and students whose mothers literacy level was middle school graduation had lower probability of detecting depressive symptoms ( OR =0.85, 0.84, 0.71, 0.76) ( P < 0.05 ). Conclusion The detection rate of depressive symptoms among students in the in depth monitoring area is high, and targeted interventions need to be developed for students to reduce the risk of mental health problems.

Objective: To explore the relationship between beverage dependence and sleep quality among college students, providing empirical evidence for improving their sleep quality. Methods: From December 2024 to January 2025, a convenience sampling method was used to conduct a questionnaire survey among 3 974 college students from four universities in Anhui Province. The Beverage Addiction Scale for College Students (BASCS) was used to assess beverage dependence, and the Self rating Scale of Sleep(SRSS) was used to evaluate sleep quality. A multivariate Logistic regression model was employed to analyze the relationship between beverage dependence and sleep quality, and a restricted cubic spline model was used to examine the dose response relationship between the two. Results: The positive rate of beverage dependence symptoms among college students was 7.6%, with positive rates of 9.6%, 13.8%, and 7.4% for the withdrawal symptoms, health effects, and dependence symptoms dimensions, respectively. The detection rate of sleep disorders was 23.6%. Multivariate Logistic regression analysis showed that after adjusting for covariates such as grade, gender, and body mass index, compared with the no beverage dependence group, students with positive beverage dependence symptoms had a higher risk of sleep disorders( OR =3.71, 95% CI =2.87-4.80, P <0.01). The OR (95% CI ) for sleep disorders among students with positive symptoms in the withdrawal symptoms, health effects, and dependence symptoms dimensions were 2.80(2.22-3.53), 2.38(1.95-2.91), and 2.45(1.89-3.18)(all P <0.01). Further analysis using a restricted cubic spline model revealed that the overall beverage dependence score and its three dimensional scores were approximately linearly related to the risk of sleep disorders among college students (all nonlinear P >0.05). Conclusions Beverage dependence is associated with sleep quality among college students. Schools should take multiple approaches, such as health education on beverage awareness, to improve students sleep quality.

Objective To investigate the status quo of health management behaviors in elderly patients with type 2 diabetes mellitus(T2DM)complicating chronic complications and the influencing factors based on health ecology theory.Methods The convenience sampling method was used to select elderly patients with T2DM complicating chronic complications in the Shanghai City from January to July 2022 as the respondents.Based on the health ecology theory,the five aspects of personality traits,psychological and behavioral traits,family and community interpersonal networks,living and working conditions and policy environment were in-vestigated.The Pearson correlation coefficient was used to analyze the correlation of various variables.The hi-erarchical linear regression was used to analyze the influencing factors of health management behaviors in eld-erly patients with T2DM complicating chronic complications.Results A total of 272 questionnaires were dis-tributed and 264 valid questionnaires were recovered,with an effective recovery rate of 97.06％(264/272).There were statistically significant differences in DSMB-Oscores among the patients with different chronic complications number,sleep quality,per capita monthly household income and medical payment methods(P＜0.05).The DSMB-Oscore in elderly patients with T2DM complicating chronic complications was positively correlated with HLSCP,DES,PACIC and CIRS scores(P＜0.05),and negatively correlated with the PAID-5 score(P＜0.05).Conclusion The health management behaviors of elderly patients with T2DM complicating chronic complications is jointly affected and acted by many factors,and it is necessary to identify and manage the related influencing factors from different aspects and different levels.

The NOD-like receptor protein 3 (NLRP3) inflammasome is essential in innate immune-mediated inflammation, with its overactivation implicated in various autoinflammatory, metabolic, and neurodegenerative diseases. Pharmacological inhibition of NLRP3 offers a promising treatment strategy for inflammatory conditions, although no medications targeting the NLRP3 inflammasome are currently available. This study demonstrates that clioquinol (CQ), a clinical drug with chelating properties, effectively inhibits NLRP3 activation, resulting in reduced cytokine secretion and cell pyroptosis in both human and mouse macrophages, with a half maximal inhibitory concentration (IC₅₀) of 0.478 μM. Additionally, CQ mitigates experimental acute peritonitis, gouty arthritis, sepsis, and colitis by lowering serum levels of interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α). Mechanistically, CQ covalently binds to Arginine 335 (R335) in the NACHT domain, inhibiting NLRP3 inflammasome assembly and blocking the interaction between NLRP3 and its component protein. Collectively, this study identifies CQ as an effective natural NLRP3 inhibitor and a potential therapeutic agent for NLRP3-driven diseases.

The level of urinary albumin is a critical indicator for the early diagnosis and management of chronic kidney disease (CKD). However, existing methods for detecting albumin are not conducive to point-of-care testing due to the complexity of reagent addition and incubation processes. This study presents a smartphone-integrated handheld automated biochemical analyzer (sHABA) designed for point-of-care testing of urinary albumin. The sHABA features a pre-loaded, disposable reagent cassette with reagents for the albumin assay arranged in the order of their addition within a hose. The smartphone-integrated analyzer can drive the reagents following a preset program, to enable automatic sequential addition. The sHABA has a detection limit for albumin of 5.9 mg/L and a linear detection range from 7 to 450 mg/L. The consistency of albumin level detection in 931 urine samples using sHABA with clinical tests indicates good sensitivity (95.78%) and specificity (90.16%). This research advances the field by providing an automated detection method for albumin in a portable device, allowing even untrained individuals to monitor CKD in real time at the patient's bedside. In the context of promoting tiered diagnosis and treatment, the sHABA has the potential to become an essential tool for the early diagnosis and comprehensive management of CKD and other chronic conditions.
