ObjectiveTo investigate the incidence rate of primary liver cancer （PLC） and the progression of liver fibrosis in chronic hepatitis B （CHB） patients with low-level viremia （LLV） （HBV DNA<2 000 IU/mL but ≥20 IU/mL） after treatment adjustment， and to provide more robust evidence for clinical practice. MethodsA retrospective analysis was performed for the clinical data of LLV patients who initially received nucleos（t）ide analogue （NAs） for at least 48 weeks at the Fifth Medical Center of PLA General Hospital from August 2007 to April 2017 and subsequently underwent NAs adjustment due to LLV， and according to the virologic response after 48 weeks of treatment adjustment， the patients were divided into LLV group and complete virological response （CVR） group （HBV DNA<20 IU/mL）. The patients were followed up once every 3‍ ‍—‍ ‍6 months till the primary endpoint event of PLC or October 2024. The incidence rate of PLC and the progression of liver fibrosis were observed， and the progression of liver fibrosis was defined as an increase of ≥1 grade in fibrosis-4 （FIB-4） index. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of continuous data with skewed distribution between two groups； the chi-square test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to calculate the cumulative incidence rate of PLC， and the Log-rank test was used for comparison between groups； the Cox regression analysis was used to investigate the risk factors for PLC， and the Logistic regression analysis was used to investigate the influencing factors for the progression of liver fibrosis. ResultsA total of 307 patients were enrolled， with a mean age of 50.0 years， and the male patients accounted for 80.5%. After 48 weeks of treatment with the adjusted NAs regimen， 254 patients （82.7%） achieved CVR， and 53 patients （17.3%） still had LLV. For the LLV group， the incidence rate of PLC was 30.2% and the rate of liver fibrosis progression was 22.6%， while for the CVR group， the incidence rate of PLC was only 13.4%， and the rate of liver fibrosis progression was 7.5%. The multivariate regression analyses showed that LLV was an independent risk factor for the onset of PLC （hazard ratio=2.623， 95% confidence interval ［CI］： 1.315‍ ‍—‍ ‍5.234， P=0.006） and the progression of liver fibrosis （odds ratio=3.213， 95%CI： 1.385‍ ‍—‍ ‍7.455， P=0.007）. ConclusionActive adjustment of treatment is needed immediately after the diagnosis of LLV to improve CVR， and if LLV persists after treatment adjustment， it is necessary to enhance the monitoring of liver fibrosis progression and PLC， so as to facilitate early diagnosis and treatment.

Medical social work, as a bridge between social welfare policies and healthcare services, is an important force in meeting the diverse and multi-level needs of the people in medical and health care. Due to the particularity of the pediatric population, pediatric medical social work is becoming one of the key areas in the development of medical social work. Beijing Children′s Hospital, Capital Medical University has established a service mode of " collaborative medical and social worker team". The medical social workers acted as supporters to assist healthcare professionals to meet the psychological and social service needs of patients and their families as much as possible, and empowered medical staff′s career development as supporters. At the same time, the medical social workers assisted in the construction of a " child friendly" medical environment, and built a social support network for patients and families. The appropriateness and future prospects of pediatric medical social work were explored, in order to provide reference for its development.

【Objective】 To investigate the association between genetic variations in the glucagon-like peptide-1 receptor (GLP-1R) gene and BP responses to sodium and potassium intake. 【Methods】 A total of 514 subjects from 124 families were recruited in Meixian County, Shaanxi Province, in 2004, resulting in the establishment of a "salt-sensitive hypertension study cohort" . The subjects followed a dietary regimen which involved a normal diet for 3 days, a low-salt diet for 7 days, a high-salt diet for 7 days, and a high-salt potassium-supplemented diet for 7 days. BP measurement was conducted at different intervention periods, and peripheral blood samples were collected. Additionally, eight single nucleotide polymorphisms (SNPs) of the GLP-1R gene were genotyped using the MassARRAY detection platform. 【Results】 The GLP-1R gene SNP rs9462472 exhibited a significant association with systolic BP, diastolic BP, and mean arterial pressure response to high-salt intervention. Similarly, SNP rs2268637 showed a significant association with systolic BP response to high-salt intervention. Furthermore, SNP rs2268637 was significantly associated with systolic BP and mean arterial pressure responses to high-salt plus potassium supplementation intervention. 【Conclusion】 Our findings indicate a significant association of genetic variations in the GLP-1R gene with BP responses to sodium and potassium intake. This suggests that the GLP-1R gene plays a role in the regulation of BP salt sensitivity and potassium sensitivity.

Objectives:To investigate the early related factors for hepatic insufficiency after hemihepatectomy and to construct and validate a nomogram model.Methods:This is a retrospective cohort study.There were 207 patients with liver tumor who underwent hemihepatectomy in the Department of Hepatobiliary Surgery, Cancer Hospital, Chinese Academy of Medical Sciences from October 2016 to December 2022. Using the random number method, patients were randomly divided into a model group( n=166) and a validation group( n=41) according to an 4∶1 ratio. There were 118 males and 48 females in the modeling group,with an age ( M(IQR)) of 59.0(13.3) years (range: 22.0 to 81.0 years),42 patients in the group with postoperative liver insufficiency and 124 patients in the group without postoperative liver insufficiency. There were 32 males and 9 females in the validation group, with an age of 54.0(19.0) years (range: 25.0 to 81.0 years). The first results of the peripheral blood test of patients within 24 hours after surgery were collected,and the independent related factors for incomplete postoperative liver function were determined by multivariate Logistic regression analysis,and related factors of postoperative incomplete liver function were screened by best subset selection. A nomogram model of the related factors of postoperative hepatic insufficiency after hemihepatectomy was constructed using R software,validated by internal and external validation of the model. Results:Multivariate logistic regression analysis showed that elevated D-dimer level and decreased antithrombin Ⅲ (AT-Ⅲ) activity within 24 hours after surgery were independent related factors for the development of postoperative hepatic insufficiency in hemihepatectomized patients. The results of the best subset selection showed that ALT, D-dimer, and AT-Ⅲ activity levels within 24 hours postoperatively were the most relevant factors for postoperative hepatic insufficiency. The R software was applied to build a nomogram prediction model based on the above three indicators in the model set, and the receiver operating characteristic(ROC) curve of the model showed an area under the curve of 0.803 and the calibration curve showed a U-index of -0.012 for the model( P=0.977). The results of the clinical decision analysis and the clinical impact curve indicated that the model had good clinical utility. The internal validation results of the Bootstrap method suggested that the model had reasonable consistency. The area under the ROC curve of the validation group model was 0.806, suggesting that the model had a good generalization prediction ability. Conclusions:The levels of ALT, D-dimer, and AT-Ⅲ activity within 24 hours after hemihepatectomy are valuable indicators for predicting liver insufficiency after hemihepatectomy. The nomogram model is reliable and can be used as an indicator for close postoperative monitoring.

Objective To investigate the long-term effect of frailty on heart failure with reduced ejection fraction(HFrEF)in elderly patients.Methods A retrospective analysis was conducted on 245 HFrEF patients aged ≥75 years admitted to our hospital from October 2017 to October 2020 due to acute exacerbation of chronic heart failure(HF).Based on their clinical frailty scale(CFS)score,they were divided into frailty group(1-4,135 cases)and non-frailty group(5-9,110 cases).Their general clinical data,clinical medication,and prognosis were compared between the two groups,and the influencing factors for frailty and death were analyzed.Results Faster heart rate,higher NT-proBNP level,and larger proportions of male,diabetes,coronary heart disease,≥5 chronic diseases,LVEF ≤35％,anemia and increased troponin I level,while lower BMI,eGFR and score of activity of daily living scale were observed in the frailty group than the non-frailty group(P＜0.05,P＜0.01).The frail group had significantly lower utilization rates of angiotensin converting enzyme inhibitors(ACEI),angiotensin receptor blockers(ARB),angiotensin receptor enkephalin inhibitors(ARNI)β receptor blockers,and sodium-glucose cotransporter 2 inhibitors than the non-frailty group(P＜0.01).Additionally,the frailty group exhibited a higher incidence of emergency room visits/readmissions within 3 months and 2-year mortality than the non-frailty group(P＜0.05,P＜0.01).Binary logistic regression analysis revealed that ≥5 chronic diseases,LVEF ≤ 35％,BMI,and GFR were independent risk factors for frailty(OR=0.167,95％CI:0.064-0.453,P=0.000;OR=0.306,95％CI:0.160-0.586,P=0.000;OR=0.868,95％CI:0.786-0.958,P=0.005;OR=0.966,95％CI:0.943-0.991,P=0.007),while ≥5 chronic disea-ses and frailty were independent risk factors for death in HF patients(P＜0.05).Conclusion The incidence of frailty is high in elderly HF patients with HFrEF.They have poor compliance to guideline directed drug therapy(GDMT).Frailty is an independent risk factor for long-term mor-tality in the patients.

Objective:To investigate the clinical outcome of biplanar botulinum toxin type A injection in alleviating platysmal bands.Methods:From November 2022 to May 2023, the clinical data of patients with platysmal bands treated by botulinum toxin type A injection in Department of Face and Neck Plastic Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, and Department of Plastic Surgery, Chengdu Badachu Cosmetic Hospital were retrospectively analyzed. The platysmal bands were marked, while patients were grinning, before injection. Using a 13 mm 30 G needle, 20 U/ml botulinum toxin was injected into the muscle layer along the bands from the clavicle direction. The dose was 1 U at a single point every 1.5 cm. Using a 3 mm 30 G needle, 10 U/ml botulinum toxin was injected into the deep surface of dermis along the bands with a single point dose of 0.5 U. Effects were evaluated by overall subjective satisfaction of patients, which were categorized into 4 grades: very satisfied, satisfied, dissatisfied, very dissatisfied. In addition, accessment by a third-party physician with global aesthetic improvement scale (GAIS) (1-5 points, the lower the score, the more significant the improvement is) and Geister platysmal band scale (0-4 points, the higher the score, the more severe the platysmal band is). Normal distribution data was represented by Mean±SD.Results:A total of 19 patients were included, including 3 males and 16 females, with the average age of 36.1 years. After a mean follow-up of 1.3 months (1-5 months), the overall subjective satisfaction was 100%(19/19). The GAIS score of third-party physicians was 1.12±0.33. 100%(19/19) of patients received a rating over moderate improvement(significant improvement in 17 cases and moderate improvement in 2 cases). The Geister platysmal band score decreased from preoperative 3.65 ± 0.33 to postoperative 0.76 ± 0.44. No serious complications were found except 5 cases of local congestion and 2 cases of injection pain, which were relieved in 1 week and 3 hours respectively. 2 cases felt mild neck weakness, but neck activity was not affected. The adverse symptoms all completely resolved spontaneously within 4 weeks. All patients have no mouth deviation, difficulty speaking, facial paralysis, allergies, or other noticeable complications.Conclusion:The injection of botulinum toxin type A in dual-plane of platysmal intramuscular layer and deep intradermal layer can effectively alleviate platysmal bands and achieve neck rejuvenation.

Objective: To investigate the proportion of physical examinations among patients with severe mental disorders and its influencing factors in Shaoxing City, Zhejiang Province, so as to provide the evidence for improving the proportion of physical examinations among patients with severe mental disorders. Methods : The epidemiological and clinical features of patients with severe mental disorders included in community management in Shaoxing City in 2022 were collected from Zhejiang Provincial Severe Mental Disorder Management Information System, including demographics, disease diagnosis and treatment, physical examination, and rescue and assistance. Factors affecting the physical examination were identified among patients with severe mental disorders using a multivariable logistic regression model. Results: A total of 25 468 patients with severe mental disorders were enrolled in Shaoxing City in 2022, including 12 151 males and 13 317 females, with a male to female ratio of 0.91∶1, and the participants had a mean age of (54.34±14.71) years. Schizophrenia was the predominant type of severe mental disorders (15 419 cases, 60.54%), and 21 374 subjects participating in the physical examinations in 2022 (83.92%). Multivariable logistic regression analysis showed that female (OR=0.901, 95%CI: 0.832-0.975), urban areas (OR=0.506, 95%CI: 0.468-0.547), mental disorders due to epilepsy (OR=1.779, 95%CI: 1.104-2.866), hospitalized treatment (6 to 10 times, OR=0.523, 95%CI: 0.401-0.681; 11 times and more, OR=0.177, 95%CI: 0.108-0.288), special diseases in outpatient (OR=1.738, 95%CI: 1.597-1.891), receiving medical assistance (OR=2.851, 95%CI: 2.616-3.107), targets of the community care and assistance groups (OR=1.653, 95%CI: 1.471-1.857) and guardian (spouse, OR=1.777, 95%CI: 1.513-2.086; children, OR=1.277, 95%CI: 1.069-1.526; parents, OR=1.342, 95%CI: 1.143-1.576) were statistically associated with the proportion of physical examinations. Conclusions The proportion of health examinations was 83.92% among patients with severe mental disorders in Shaoxing City in 2022. Gender, residence, guardian, disease diagnosis, times of hospitalized treatment, medical assistance, special diseases in outpatients and target of community care and assistance groups were factors affecting health examinations among patients with severe mental disorders.
