Objective: To evaluate the effect of weight monitoring feedback intervention among primary school students, so as to provide the evidence for strengthening children's weight management. Methods: In October 2023, students from grades four to six in a primary school in Hangzhou City were selected and randomly assigned to a control group and an intervention group on a class-by-class basis. The included primary school students had their height and weight measured at a fixed time each week, and the results were fed back to their parents in the form of cards. The cards for the control group contained knowledge about healthy lifestyles, while those for the intervention group additionally included information on body mass index (BMI), BMI grouping, and BMI ranking. Overweight and obesity were determined according to the age- and gender-specific criteria in the Screening for Overweight and Obesity among School-aged Children and Adolescents. After a 9-month intervention period, the prevalence rates of overweight and obesity and lifestyle behavior data between the two groups before and after the intervention were compared by a generalized linear mixed model, in order to assess the effectiveness of the weight monitoring information feedback intervention. Results: The intervention group consisted of 368 students, including 208 boys (56.52%) and 160 girls (43.48%). The majority of students were 11 years, with 153 students accounting for 41.58%. The prevalence rate of overweight and obesity was 24.18%. The control group had 324 students, with 180 boys (55.56%) and 144 girls (44.44%). The predominant age was also 11 years, with 128 students accounting for 39.51%. The prevalence rate of overweight and obesity was 25.31%. Before the intervention, there were no statistically significant differences between the two groups in terms of gender, age, prevalence rate of overweight and obesity, eating habits, exercise situation, and sleep patterns (all P>0.05). After the intervention, there were significant interactions between group and time for the prevalence rate of overweight and obesity, the frequency of moderate-intensity exercise per week, and adequate sleep in the two groups (all P<0.05). The prevalence rate of overweight and obesity in the intervention group (OR=0.461, 95%CI: 0.252-0.845) was lower than that in the control group. The proportions of students in the intervention group who engaged in moderate-intensity exercise ≥4 times per week (OR=1.315, 95%CI: 1.033-1.675) and had adequate sleep (OR=1.402, 95%CI: 1.049-1.875) were higher than those in the control group. Conclusion Weight monitoring feedback can reduce the incidence of overweight and obesity among primary school students and has a certain improving effect on lifestyle behaviors such as exercise and sleep.

Dental implantology has developed rapidly for over half a century,since pure titanium(99.7％)dental cylindrical threaded implants were exploited and osseointegration was introduced in 1960s by Prof.Br?nemark.The long term retention rates of 10 years or more are over 95％.However,the biological complications jeopardize the long term effects of dental implant treatment seriously.The prevalence of dental implant biological complications varies greatly among different reports resulting from the disparities on the defini-tions of dental implant biological complications.After analyzing and summarizing the major opinions proposed internationally in recent years,the consensus for the definition of dental implant biological complications has been reached.Generally the dental implant biologi-cal implications can be classified into early stage(before restoration)biological complications and late stage(after restoration)biological complications.The early stage biological complications include acute and chronic infections,pain,soft tissue deficiency,and osseointegration failure,etc.The late stage complications include peri-implant diseases(peri-implant mucositis and peri-implantitis),soft tissue deficiency around implant,implant loosening and dropping off,etc.The various risk factors related to different dental implant biological complications,the strategies of the prevention and treatment for the dental implant biological complications have been discussed comprehensively,and the consensus has been reached.It is aimed to advocate the dentist to pay more attention to the early prevention of the biological implant complications,to promote more researches on the implant biological complications,and to help elevate the level of dental implantology in our country.

Health communication is the most core element in health education and health promotion.This paper summarizes and analyzes the research in China related to the evaluation of health communication effects through different media.It finds that the current evaluation indicators of communication effects are generally focused on changes in awareness rates.Traditional media and new media,as different types of communication mediums with their own advatages and limitations,do not have unified indicators to scientifically evaluate their communication effects in China,Due to the interdisciplinary nature of health communication,qualitative research methods(such as the Delphi method)have not been fully applied by researchers in the field of public health in China.This paper aims to sort out and compare various effects evaluation indicatorsof health communication with different media from current research through a literature review,and to provide evidences for improving a comprehensive and practical effect evaluation system of health communication in the future.

Background and aim:Few studies have reported hepatitis B surface antigen(HBsAg)kinetics after nucleos(t)ide analog(NA)discontinuation in patients with noncirrhotic chronic hepatitis B(CHB).The study specifically investigated long-term HBsAg kinetics after NA discontinuation. Methods:Between January 2014 to January 2024,this study prospectively enrolled 106 outpatients with noncirrhotic CHB who met the discontinuation criteria after NA consolidation treatment.Demographic,clinical,and laboratory data were collected and analyzed after NA discontinuation. Results:Ninety-six patients who finished 5 years of follow-up were included.HBsAg remained unde-tectable in 29 patients with end of treatment(EOT)HBsAg negativity.Among 67 patients with EOT HBsAg positivity,HBsAg seroclearance occurred in 12(17.9％)patients with an estimated annual inci-dence of HBsAg seroclearance of 3.6％.Patients with EOT HBsAg levels of ≤1000 IU/mL had a higher HBsAg seroclearance rate than those with EOT HBsAg levels of＞1000 IU/mL(33.3％vs.5.4％).The pro-portion of patients with HBsAg ≤1000 IU/mL increased during follow-up.Logistic regression analysis indicated that the EOT HBsAg level was an independent factor for HBsAg seroclearance and an HBsAg level decline exceeding 1 log10 IU/mL.The optimal EOT HBsAg cutoff for both HBsAg seroclearance and an HBsAg level decline exceeding 1 log10 IU/mL was 359 IU/mL. Conclusions:Patients with EOT HBsAg negativity experienced no relapse and maintained HBsAg sero-clearance during 5 years of follow-up after NA discontinuation.A higher HBsAg seroclearance rate can be obtained in patients with EOT HBsAg levels of ≤1000 IU/mL during 5 years of follow-up after NA discontinuation.Close monitoring and proper NA retreatment are recommended to guarantee the safety of NA discontinuation.

Clinical cure (herein referred to as functional cure) is currently recognized as the ideal therapeutic goal by the guidelines for the prevention and treatment of chronic hepatitis B (CHB) at home and abroad. China has achieved significant results in research and exploration based on pegylated interferon alpha therapeutic strategies to promote the effectiveness of CHB clinical cure rates in clinical practice. The summary and optimization of clinical cure strategies in different clinical type classifications, as well as the exploration of clinical cure continuity and long-term outcomes, are of great significance for solving the current bottleneck problem and our future efforts in the developmental directions of clinical cure in CHB populations.

Objective:To review the scope of research on the application of blood flow restriction training in the rehabilitation of patients undergoing anterior cruciate ligament (ACL) reconstruction.Methods:According to the research method of scoping review, computer searches were conducted on China National Knowledge Infrastructure, Wanfang Database, China Biology Medicine disc, VIP, Cochrane Library, PubMed, Embase, with the search period was from eatablishment of databases to December 31, 2022. The included literatures were screened, summarized and analyzed.Results:A total of 16 literatures were included, all of which were randomized controlled trials. The basic content of blood flow restriction training intervention included 8 aspects, such as intervention time, training intensity, training amount, training mode, frequency, interval time, training cycle and blood flow restriction pressure. The effect evaluation mainly involved two kinds of indexes, namely safety indicators and efficacy indicators.Conclusions:Blood flow restriction training can effectively enhance muscle strength and improve knee joint function in patients undergoing ACL reconstruction. Future studies should focus on exploring the best intervention strategy, formulating standardized and unified evaluation criteria and providing the best blood flow restriction training program for patients undergoing ACL reconstruction.

Objective:To explore the early predictors for clinical cure by sequential combined interferon therapy in nucleos(t)ide analogues (NAs) experienced patients with chronic hepatitis B(CHB).Methods:CHB patients received NAs treatment≥one year with hepatitis B surface antigen (HBsAg) ≤1 500 IU/mL, hepatitis B e antigen (HBeAg) negative and hepatitis B virus (HBV) DNA <100 IU/mL in the Third Affiliated Hospital of Sun Yat-sen University from June 2016 to September 2019 were included. According to the different treatment regimens, the patients were divided into interferon alone for 48 weeks group (group A), interferon combined with NAs for 12 weeks and continued NAs treatment for 48 weeks group (group B), interferon combined with NAs for 48 weeks group (group C). Basic data such as age and gender of patients were collected. HBsAg, hepatitis B surface antibody (anti-HBs) and alanine aminotransferase (ALT) were monitored at week 4, 8, 12, 24, 36 and 48. The decline of HBsAg from baseline, and the rates of clinical cure at 48 weeks were analyzed. The independent sample t test, chi-square test and rank sum test were used for statistical analysis. Logistic regression analysis was used to achieve the early prediction index of clinical cure at week 48. Results:A total of 1 020 CHB patients were followed up regularly for at least five time points. The rates of clinical cure at week 48 in group A, B and C were 34.6%(157/454), 32.7%(69/211) and 33.5%(119/355), respectively, with no statistical significance ( χ2=0.25, P=0.883). Patients were divided into the cured group (345 cases) and the uncured group (675 cases) according to the clinical outcomes at week 48. The age ((38±13) years old vs (43±12) years old), baseline HBsAg (131.00(359.80) IU/mL vs 437.60(531.50) IU/mL) and the proportion of male patients (81.7%(282/345) vs 89.5%(604/675)) of patients in the cured group were all lower than those of patients in the uncured group. The differences were all statistically significant ( t=6.32, Z=12.67, χ2=11.99, respectively, all P<0.050). There were 212 patients in the cured group who achieved clinical cure within 24 weeks of treatment. The rate of clinical cure at 48 weeks in patients whose HBsAg at week 4 decreased from baseline was higher than that in patients with increased HBsAg (41.6%(149/358) vs 28.2%(108/383)). The difference was statistically significant ( χ2=14.13, P<0.001). The rate of clinical cure at week 48 in patients with HBsAg at week 12 decreased ≤34.03% of baseline was only 6.9%(13/188). Multivariate logistic regression analysis showed that age (odds ratio ( OR)=0.962, 95% confidence interval ( CI) 0.936 to 0.989, P=0.006), HBsAg level at week 24 ( OR=0.950, 95% CI 0.934 to 0.966, P<0.001) and anti-HBs level at week 24 ( OR=1.012, 95% CI 1.005 to 1.019, P=0.001) were early predictors for clinical cure at week 48 of treatment in NAs experienced CHB patients. Conclusions:Clinical cure of NAs experienced CHB patients received sequential combined interferon therapy mostly occurs in the early stage (within 24 weeks). Age, HBsAg level at week 24, and anti-HBs level at week 24 are early predictors for clinical cure of 48-week sequential combined interferon treatment.
