Functional cure of chronic hepatitis B （CHB） is defined as HBsAg<0.05 IU/mL and serum HBV DNA<10 IU/mL for at least 24 weeks after discontinuation of antiviral therapy. This requires suppression of HBV replication and reduction of viral antigen production， as well as restoration of immune response to HBV infection. About 30% — 50% of highly selected CHB patients treated with nucleos（t）ide analogues can achieve functional cure after add-on therapy or monotherapy with pegylated interferon-α or a finite course of treatment with nucleos（t）ide analogues among patients with HBsAg<100 IU/mL. At present， clinical trials are being conducted for more than 40 types of novel anti-HBV drugs and immunomodulators. The combination of drugs that inhibit viral replication， reduce antigen burden， and restore immune response to HBV infection may be an ideal strategy to achieve the functional cure of CHB. However， further studies are needed to determine the optimal drug combination， the timing and sequence of medication， and the duration of treatment.

AIM: To explore the efficacy of 0.05% cyclosporine A combined with olopatadine eye drops in treating allergic conjunctivitis-related dry eye disease.METHODS: A total of 63 patients(63 eyes)with allergic conjunctivitis-related dry eye disease in the People's Hospital of Guangxi Zhuang Autonomous Region from August 2022 to April 2023 were enrolled and randomly divided into control group(n=33)and observation group(n=30). The patients of the control group were administrated with 0.1% olopatadine eye drops and 0.3% sodium hyaluronate eye drops, while the observation group was administrated with 0.1% olopatadine eye drops and 0.05% cyclosporine A eye drops. The ocular surface disease index(OSDI), total ocular symptom score(TOSS), conjunctival congestion score, conjunctival papillae and follicle score, Schirmer I test(SⅠt), tear meniscus height(TMH), meibomian gland secretion ability and property score, meibomian gland loss area score, corneal fluorescein staining(CFS), tear film break-up time(BUT), noninvasive first tear film break-up time(NIBUTf), noninvasive average tear film break-up time(NIBUTav)before and after treatment and the drug safety during the treatment period of both groups of patients were evaluated.RESULTS: After treatment, OSDI, TOSS, conjunctival congestion score, conjunctival papillae and follicle score, SⅠt, TMH, meibomian gland secretion ability score and property score, CFS, BUT, NIBUTf, and NIBUTav of the observation group showed improvements compared with those before treatment(all P<0.017). Among these, OSDI, TOSS, conjunctival congestion score, conjunctival papillae and follicle score, BUT, NIBUTf, and NIBUTav demonstrated significant improvement compared with the control group(all P<0.05). There was no statistically significant difference in meibomian gland loss area score between the two groups before and after treatment(P>0.05). During the treatment period, there were no local or systemic adverse reactions.CONCLUSION: The combined use of 0.05% cyclosporine A and olopatadine eye drops can significantly improve ocular discomfort symptoms of patients with dry eye disease associated with allergic conjunctivitis, such as red eyes, itchy eyes and foreign body sensation, promote tear film stability and have high safety.

Objective: To explore the association between mental health status and adverse childhood experiences (ACEs) among sexual minority college students, so as to provide a scientific basis for mental health education and health promotion in universities. Methods: From January to February 2024, convenience and cluster sampling methods were used to select 1 792 college students from 11 colleges in Guangxi. A self reporting method was applied to identify 476 sexual minority individuals. The Symptom Check-List 90 (SCL-90) and the Simplified Chinese Adverse Childhood Experiences International Questionnaire (SC-ACE-IQ) were employed to assess mental health and ACEs. Multivariate Logistic regression analysis was conducted to examine the associations. Results: The detection rates of all psychological issues among sexual minority college students in Guangxi were significantly higher than those of non sexual minority college students ( χ 2=56.01-91.39, all P <0.01). Except for physical neglect, bullying, and community violence, sexual minority students exhibited higher reporting rates of other ACEs types compared to nonsexual minority students ( χ 2= 4.52-13.34, all P <0.05). The total ACEs score for college students was 1.00 (1.00, 2.00), while the SCL-90 total score was 96.00 (113.00, 160.00). Spearman correlation analysis revealed a positive correlation between ACEs total scores and SCL-90 total scores ( r=0.29, P <0.05). Additionally, all ACEs subscales, including emotional neglect, physical neglect, emotional abuse, sexual abuse, parental loss, domestic violence, and community violence were positively correlated with corresponding SCL-90 subscale scores ( r =0.05-0.22, all P <0.05). Multivariate Logistic regression analysis showed that family violence increased the risk of mental health issues for sexual minority students ( OR=1.61, 95%CI =1.26-2.09); emotional neglect ( OR= 1.05 , 95%CI =1.00-1.10), physical neglect ( OR=1.20, 95%CI =1.06-1.35), sexual abuse ( OR=1.49, 95%CI =1.15-1.93) increased mental health risks for non sexual minority students (all P <0.05). The cumulative effects of ACEs were all statistically significant in the total sample and both subgroups (all P <0.05). Conclusion Mental health status among sexual minority college students in Guangxi is associated with ACEs, and their well being requires active attention

Objective To investigate the epidemiological characteristics and diagnosis of imported Plasmodium malariae and P. ovale malaria cases in Anhui Province, Hubei Province, Zhejiang Province, Guangxi Zhuang Autonomous Region and Henan Province from 2014 to 2021, so as to provide insights into malaria control in these five provinces. Methods All data pertaining to malaria cases reported in five provinces of China were captured from Chinese Disease Control and Prevention Information System from 2014 to 2021, and the epidemiological characteristics of imported P. malariae and P. ovale malaria cases were analysed using a descriptive epidemiological method. The duration from onset of malaria to initial diagnosis, duration from initial diagnosis to definitive diagnosis, institutions of initial and definitive diagnoses, and proportion of correct malaria diagnosis at initial diagnosis were statistically analyzed. Results A total of 1 223 imported P. malariae and P. ovale malaria cases were reported in Anhui Province, Hubei Province, Zhejiang Province, Henan Province and Guangxi Zhuang Autonomous Region from 2014 to 2021, there were 158 P. malariae malaria cases (12.92%) and 1 065 P. ovale malaria cases (87.08%). Totally 98.53% (1 205/1 223) of the imported malaria cases were from Africa, with Angola (18.99%, 30/158), Nigeria (11.39%,18/158), Cameroon (10.76%, 17/158), Ghana (10.13%, 16/158) and the Democratic Republic of the Congo (10.13%,16/158) as predominant countries where P. malariae malaria cases were from, and Ghana (23.19%, 247/1 065), Cameroon (14.74%, 157/1 065), Nigeria (9.39%, 100/1 065) and Angola (6.95%, 74/1 065) as predominant countries where P. ovale malaria cases were from. There were significant differences in the duration from onset of malaria to initial diagnosis (χ² = 27.673, P = 0.000) and duration from initial diagnosis to definitive diagnosis of P. malariae and P. ovale malaria cases (χ² = 29.808, P = 0.000), and the proportions of correct initial diagnosis of P. malariae and P. ovale malaria cases were 38.61% (61/158) and 56.53% (602/1 065). There were 74.69% (118/158) of P. malariae malaria cases with definitive diagnosis in county-, city-, and province-level medical institutions, and 79.25% (844/1 065) of P. ovale malaria cases with definitive diagnosis in county- and city-level medical institutions and county-level centers for disease control and prevention. Conclusions The imported P. malariae and P. ovale malaria cases in Anhui Province, Hubei Province, Zhejiang Province, Henan Province and Guangxi Zhuang Autonomous Region from 2014 to 2021 were mainly returned from Africa and the proportion of correct diagnosis of P. malariae and P. ovale malaria was low at initial diagnosis. Persistent improvements in the diagnostic capability of malaria are required in medical institutions.

ObjectiveTo understand the protective effect of pentavalent rotavirus （RV） vaccine in preventing infectious diarrhea among infants and young children， and to provide a basis for formulating prevention and control strategies for this population. MethodsA retrospective cohort study was conducted to follow up resident children born in Pinghu City from January 2019 to June 2021 for two years. Data on morbidity and pentavalent RV vaccine inoculation were collected to analyze the incidence density of rotavirus infection among children inoculated with different doses of the pentavalent RV vaccine， and to calculate the vaccine protection rate. ResultsA total of 5 141 resident children were surveyed， with a RV vaccination rate of 31.63% and a full vaccination rate of 30.83%. There were 154 cases of RV infection， with an incidence density of 1 392.69/100 000 person-years. Among the 875 migrant children （17.02%）， the full vaccination rate was 20.46%， while among the 4 266 local children （82.98%）， the full vaccination rate was 32.96%. The difference in full vaccination rate between migrant children and local children was statistically significant （χ²=53.209， P<0.001）. The proportions of boys and girls were 51.94% and 48.06%， respectively， with a full vaccination rate of 29.74% and 32.01%， respectively； and the difference was not statistically significant （χ²=3.111， P=0.078）. The proportions of children with normal birth weight and abnormal birth weight were 91.56% and 8.44%， respectively， with a full vaccination rate of 31.82% and 20.05%， respectingly； and the difference was statistically significant （χ²=25.852， P<0.001）. Among the 3 515 children who were not vaccinated with the pentavalent RV vaccine， 118 of which were infected， with an incidence density of 1 503.32/100 000 person-years （with an incidence rate of 3.36%）. Among the 41 children who were partially vaccinated （received only 1-2 doses）， the incidence density was 1 058.54/100 000 person-years （with an incidence rate of 2.44%）. Among the 1 585 fully vaccinated children， 35 of which were infected， with an incidence density of 1 123.96/100 000 person-years （with an incidence rate of 2.21%）； and the difference in incidence rate was statistically significant （χ²=4.988， P=0.026）. The protection rate for partial vaccination was 28.00% （95%CI：22.00%‒33.50%）， while for full vaccination was 35.10% （95%CI： 29.80%‒40.00%）. ConclusionPentavalent RV vaccination can effectively prevent rotavirus infection in infants and young children， in which the full vaccination is more effective than partial vaccination. It is recommended to strengthen the monitoring of circulating RV strains in the city， develop more targeted vaccines， and increase the RV vaccine coverage rate and full vaccination rate among infants and young children through the expansion of the national immunization program and enhancement of public education， so as to effectively reduce the incidence of infectious diarrhea in infants and young children.
