Objective To investigate the prevalence, distribution characteristics, and influencing factors of mental health problems among the elderly, and to provide a scientific basis for policy-making.  Methods A convenience sampling method was used to investigate depression, anxiety, and cognitive function among permanent residents aged 65 and older at 59 mental health care sites for the elderly in Hubei Province. Multinomial logistic regression was employed to analyze influencing factors. Results The screening rates for depression, anxiety, and cognitive function at critical/high-risk levels among the elderly in Hubei Province were 9.7%, 5.4%, and 12.2%, respectively. Urban elderly had lower risks of depression and cognitive function at critical/high-risk levels compared to rural elderly (OR for critical depression = 0.640, P < 0.001; OR for high-risk depression = 0.595, P = 0.012; OR for critical cognitive function = 0.448, P < 0.001; OR for high-risk cognitive function = 0.188, P < 0.001). Six key population groups had higher risks of depression, anxiety, and cognitive function at critical/high-risk levels than others (OR for critical depression = 1.463, P < 0.001; OR for high-risk depression = 1.912, P < 0.001; OR for critical anxiety = 1.462, P < 0.001; OR for high-risk anxiety = 2.882, P < 0.001; OR for critical cognitive function = 1.381, P < 0.001; OR for high-risk cognitive function = 2.345, P < 0.001). A higher number of chronic diseases was associated with increased risks of critical and high-risk depression (OR for critical = 1.316, P < 0.001; OR for high-risk = 3.677, P < 0.001) and cognitive impairment (OR for critical depression = 1.316, P < 0.001; OR for high-risk depression = 3.677, P < 0.001; OR for critical anxiety = 1.512, P < 0.001; OR for high-risk anxiety = 1.801, P < 0.001). Conclusion It is recommended to expand mental health care sites in rural areas, improve the layout of mutual-support elderly care facilities, and explore sustainable models for rural elderly care. Efforts should also focus on enhancing social participation among the elderly through community-based activities, and strengthening cognitive screening and emotional regulation interventions, with particular attention to the mental health needs of older, isolated, and chronically ill individuals.

Objective To investigate the expression levels of serum high-mobility group box 1(HMGB1),soluble CD163(sCD163),and prostaglandin E2(PGE2)in patients with hepatitis B virus-related chronic-on-acute liver failure(HBV-ACLF),and to evaluate the value of the three indicators used alone or in combination in predicting prognosis.Methods A total of 76 patients with HBV-ACLF who were hospitalized in Department of Infectious Diseases,The First Affiliated Hospital of Xinxiang Medical University,from July 1,2022 to September 30,2023 were enrolled,and according to the 28-day prognosis,they were divided into survival group with 48 patients and death group with 28 patients.General data were collected,Model for End-Stage Liver Disease(MELD)score was calculated,and ELISA was used to measure the serum levels of HMGB1,sCD163,and PGE2.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 non-normally distributed continuous data between two groups;the chi-square test was used for comparison of categorical data between two groups.The Spearman rank correlation test was used to analyze the correlation of HMGB1,sCD163,and PGE2 with MELD score;the receiver operating characteristic(ROC)curve was used to analyze the value of HMGB1,sCD163,and PGE2 used alone or in combination in predicting the prognosis of HBV-ACLF patients.Results There were significant differences between the two groups in total bilirubin,white blood cell count,the percentage of neutrophils,procalcitonin,serum amyloid A,interleukin-6,serum sodium,and serum creatinine(all P＜0.05).Compared with the survival group,the death group had significantly higher serum levels of HMGB1(Z=-2.997,P=0.003)and sCD163(Z=-2.972,P=0.003),a significantly higher MELD score(t=-6.997,P＜0.001),and a significantly lower serum level of PGE2(Z=-4.909,P＜0.001).The Spearman rank correlation test showed that HMGB1 and sCD163 were positively correlated with MELD score(r=0.431 and 0.319,both P＜0.05),while PGE2 was negatively correlated with MELD score(r=-0.412,P＜0.05).The ROC curve analysis showed that HMGB1,sCD163,and PGE2 used alone had an area under the ROC curve(AUC)of 0.717,0.716,and 0.856,respectively,while the combination of the three indicators had the highest predictive value,with an AUC of 0.930,a sensitivity of 0.778,and a specificity of 0.920.Conclusion Serum HMGB1,sCD163,and PGE2 used alone or in combination have a good reference value in predicting the prognosis of HBV-ACLF patients,and the combination of the three indicators has the highest predictive value,which holds promise for further observation and research.

Objective To accurately encode pelvic organ prolapse and ensure data accuracy.Methods ICD-10 coding analysis was performed in combination with the professional knowledge of the International Classification of Diseases(ICD-10)and specific clinical cases of pelvic organ prolapse.Results Vaginal anterior wall prolapse,regardless of severity,was encoded as N81.1;vaginal posterior wall prolapse,regardless of severity,as N81.6;uterine prolapse grade Ⅰ and Ⅱ,regardless of the presence or absence of vaginal anterior and posterior wall prolapse,as N81.2;uterine prolapse grade Ⅲ,whether the prolapse of the anterior and posterior vaginal walls is combined,or what level of the severity of the prolapse,as N81.3;cervical prolapse staging,regardless of severity or presence of vaginal anterior and posterior wall prolapse,as N81.2.In addition,the N81.-code does not include genital prolapse complicating pregnancy(O34.5),prolapse and hernia of ovary and fallopian tube(N83.4),vaginal fornix prolapse after hysterectomy(N99.3).Conclusion To ensure accurate coding,the composite coding rules must be cross-checked with volume one.ICD-10 failed to reflect the severity of vaginal prolapse in clinical practice.To consider the severity,coding should be extended in the N81.-segment.It is essential for coders to actively acquire clinical knowledge,rein-force professional knowledge,and enhance their responsibility to improve their coding proficiency and ensure data accuracy.

Objective·To study early expression levels of serum heparin-binding protein(HBP)and its potential value in early alarming for prognosis and occurrence of sepsis in patients with severe bums.Methods·Retrospective analysis was performed on medical records of 52 severely burned patients admitted to the Department of Bum and Plastic,Ruijin Hospital,Shanghai Jiao Tong University School of Medicine during January 2021 to May 2023.General data of patients on gender,age,total bum area,body mass index(BMI),and whether endotracheal intubation or incision was performed were collected.The level of HBP,serum procalcitonin(PCT),serum C-reactive protein(CRP)and the count of white blood cells within 48 h of admission were collected.The scores of acute physiological and chronic health assessment evaluation Ⅱ(APACHE Ⅱ)and sequential organ failure assessment(SOFA)within 48 h of admission were collected.Patients were divided into death group and survival group according to the status at discharge.According to whether sepsis occurred during hospitalization,the patients were divided into sepsis group and non-sepsis group.According to whether shock occurred,the septic patients were divided into sepsis without shock group and septic shock group.Risk factors for death,sepsis,and septic shock in severely burned patients were analyzed by using Logistic regression models.Receiver operator characteristic(ROC)curve analysis was established to study risk factors,which may alarm the occurrence of poor prognosis,sepsis,and septic shock.Results·Compared with the survival group,patients in the death group were older,and the difference was statistically significant(P=0.036).Differences in burn area and whether tracheal intubation or tracheotomy was performed were statistically significant in patients with or without sepsis(P=0.011,P=0.001).Compared with the survival group,the serum HBP levels were higher in the death group,and the difference was statistically significant(P=0.002).Compared with the non-sepsis group,patients in the sepsis group had higher levels of serum HBP,APACHE Ⅱ scores,and SOFA scores,and the differences were statistically significant(all P＜0.05).The differences in other indicators were not statistically significant.Compared with the sepsis without shock group,the septic shock group had higher HBP levels,with a statistically significant difference(P=0.008).Logistic regression analysis showed that HBP was an independent risk factor for death in patients with severe burns during hospitalization and also an independent risk factor for the occurrence of septic shock in patients with sepsis after severe burns.ROC curve analysis showed that the area under the curve(AUC)for HBP in predicting patient mortality during hospitalization was 0.798;when HBP ≥147.03 ng/mL,its sensitivity and specificity were 88.33％and 70.00％,respectively.The AUC for HBP in predicting the occurrence of septic shock in patients with sepsis after severe burns was 0.789;when HBP ≥147.03 ng/mL,its sensitivity and specificity were 90.00％and 63.20％,respectively.Conclusion·The level of serum HBP within 48 h of admission might be used as an early alarming index for prognosis in patients with severe burns and for the occurrence of septic shock in patients with sepsis following severe burns.

Objective To explore the effects of disuse-induced architectural changes in the osteocytic lacunar-canalicular system(LCS)on the fluid dynamic microenvironment of osteocytes under mechanical stimulus.Methods First,taking the axially loaded mice tibia as the object,a multi-scale model of'whole bone-single osteocyte LCS'was established.Subsequently,pressure gradients and other results obtained from the whole-bone poroelastic finite element model were used as boundary conditions for the single-osteocyte LCS model to calculate the flow velocity and shear stress around osteocytes.Finally,a design of experiment(DOE)method was used to determine the individual and interactive effects of the LCS architectural parameters(lacunar volume,lacunar shape,and canalicular diameter)on the osteocytic fluid dynamic microenvironment within the LCS.Results When the lacunar volume,lacunar shape,and canalicular diameter changed from normal to disused,the flow velocity increased by 5.3%,39.3%,and 37.0%,respectively.The DOE results showed that the lacunar shape and canalicular diameter had a significant effect on fluid velocity and shear stress(P<0.05),with a contribution ratio of 0.38∶0.62,whereas the lacunar volume and interaction of architectural parameters had no significant effects.Conclusions Disuse-induced changes in canalicular diameter and lacunar shape were the main factors affecting the osteocytic fluid dynamic environment within the LCS under mechanical stimulus.Appropriate exercise methods are expected to prevent disuse-induced bone loss caused by space weightlessness and other conditions.

ObjectiveTo compare the neuropsychological development of infants with different types of morphologic cranial deformities. MethodsA total of 954 children aged 0 to 18 months who came to Beijing Children's Hospital from January, 2020 to August, 2021 for cranial measurement and neuropsychological development measurement were selected. They were divided into brachycephaly group, plagiocephaly group, asymmetric brachycephaly group, scaphocephaly group and normal group according to the cranial measurement. The development quotient (DQ) was calculated from Children Neuropsychological Development Scale (0-6). ResultsThere were 449 cases in the normal group, 94 cases in the brachycephaly group, 201 cases in the plagiocephaly group, 82 cases in the asymmetric brachycephaly group and 128 cases in the scaphocephaly group. The detection rate of Developmental Edge and Delay (DQ < 85) for gross motor area was the most in brachycephaly group (60.6%), and it was the most for fine motor (64.6%), language (45.1%), adaption (51.2%) and social behavior areas (48.8%) in the asymmetrical brachycephaly group. The DQ was different among the five groups for all the areas except the language area (F > 14.835, P < 0.001); compared with the normal group, DQ decreased for all the four areas in all the groups except the scaphocephaly group; DQ of the areas of gross motor, fine motor and adaption was more in the plagiocephaly group than in the asymmetric brachycephaly group (P < 0.05), while DQ of the areas of gross motor and fine motor was more in the plagiocephaly group than in the brachycephaly group (P < 0.05). Linear regression analysis showed that, DQ negative linear correlated with the cephalic ratio and cranial vault asymmetry index (|B| > 0.967, P < 0.05). ConclusionAmong four kinds of cranial malformation in infants, the neuropsychological development of the scaphocephaly group is almost normal, and somehow delays for brachycephaly, plagiocephaly and asymmetric brachycephaly, especially in the aspects of gross motor, fine motor, adaption and social behavior. The more serious the cranial deformity, the greater the risk of developmental delay in each functional area.

Objective     To explore the clinical efficacy and learning curve of robot-assisted thymectomy via subxiphoid approach. Methods    The clinical data of patients with robot-assisted thymectomy surgery via subxiphoid approach performed by the same surgical team in the Department of Thoracic Surgery of Shanghai Pulmonary Hospital from February 2021 to August 2022 were retrospectively analyzed. The cumulative sum (CUSUM) analysis and best fit curve were used to analyze the learning curve of this surgery. The general information and perioperative indicators of patients at different learning stages were compared to explore the impact of different learning stages on clinical efficacy of patients. Results    A total of 67 patients were enrolled, including 31 males and 36 females, aged 57.10 (54.60, 59.60) years. The operation time was 117.00 (87.00, 150.00) min. The best fitting equation of CUSUM learning curve was y=0.021 2x3–3.192 5x2 +120.17x–84.444 (x was the number of surgical cases), which had a high R2 value of 0.977 8, and the fitting curve reached the top at the 25th case. Based on this, the learning curve was divided into a learning period and a proficiency period. The operation time and intraoperative blood loss in the proficiency stage were significantly shorter or less than those in the learning stage (P<0.001), and there was no statistical difference in thoracic drainage time and volume between the two stages (P>0.05). Conclusion    The learning process of robot-assisted thymectomy via subxiphoid approach is safe, and this technique can be skillfully mastered after 25 cases.

This paper mainly analyzes the literature on the training system of physiotherapists at home and abroad in the past 15 years, and compares the training mode, curriculum setting, current situation and application direction of physiotherapists domestic and abroad. The main findings are as follows: at present, the training objectives of Chinese physiotherapists are not clear, the training methods and teaching materials are outdated, the source of teachers are not standardized, the identification of professional qualifications are not completed, and the gap between relevant talents and market demand is large. It is suggested to establish a standardized curriculum and syllabus for physiotherapists, develop a unified industry access and qualification recognition, formulate a training mode which is in line with the national conditions, and focus on solving the imbalance between supply and demand of physiotherapists.
