Objective: To explore the relationship of family function with sleep and externalizing problem behaviors of preschool children, so as to provide a guidance for externalizing problem prevention and intervention among preschool children. Methods: From October 2023 to January 2024, a convenience sampling method was used to select 5 138 preschool children from kindergartens in 8 districts of Wuhan City, Hubei Province. Parents completed the survey for Family Adaptability and Cohesion Scale, children s sleep habits and Child Behavior Checklist (CBCL). Spearman correlation analysis was used to examine the correlation of family function with scores of sleep quality and externalizing problem behaviors among preschool children. A mediation model analysis and bootstrap test were conducted to further investigate the mediating role of sleep quality between family function and externalizing problem behaviors. Mplus 8.7 software was used for latent profile analysis of family function. Results: The reported rates of poor sleep quality and externalizing problem behaviors among preschool children were 11.8% ( n =607), 20.0% ( n =1 026). The relevant analysis results showed that family function was negatively correlated with sleep quality and externalizing problem behaviors ( r = -0.20, -0.23), and sleep quality was positively correlated with externalizing problem behaviors ( r =0.27) ( P <0.01). The mediation effect test showed that family function negatively predicted externalizing problem behaviors ( β =-0.079) and sleep quality ( β = -0.075), while sleep quality positively predicted externalizing problem behaviors ( β =0.215) ( P <0.01). The latent profile analysis results showed that family function could be classified into 4 categories: high family function group (23.01%), upper middle family function group (44.65%), moderate family function group (26.24%) and low family function group (6.11%). Compared to high family function, the other three categories significantly positively predicted externalizing problem behaviors, and the mediating effects of sleep quality on different categories of family function were statistically significant [upper middle family function: mediation effect value was 0.022 (95% CI =0.004-0.041) and direct effect value was 0.329 (95% CI =0.263-0.396); middle family function: mediation effect value was 0.087 (95% CI =0.063-0.115) and direct effect value was 0.491 (95% CI =0.416-0.565); low family function: mediation effect value was 0.144 (95% CI =0.107-0.185) and direct effect 0.621 (95% CI =0.503-0.740)] ( P < 0.05 ). Conclusion Family function negatively predicts the externalizing problem behaviors of preschool children, and sleep quality plays a partial mediating role.

ObjectiveTo investigate the application of the novel inflammatory factor adsorption column CA280 combined with low-dose plasma exchange （LPE） in patients with acute-on-chronic liver failure （ACLF）. MethodsA prospective cohort study was designed， and a total of 93 ACLF patients who were admitted to The Ninth Hospital of Nanchang from June 2023 to January 2025 were enrolled and randomly divided into DPMAS+LPE group with 50 patients and CA280+LPE group with 43 patients. In addition to comprehensive medical treatment， the patients in the DPMAS+LPE group received DPMAS and LPE treatment， and those in the CA280+LPE group received CA280 and LPE treatment. The two groups were observed in terms of routine blood test results， liver function parameters， renal function markers， electrolytes， coagulation function parameters， cytokines， adverse events， and 28-day prognosis before surgery （baseline）， during surgery （DPMAS or CA280）， and after surgery （after sequential LPE treatment）. The paired t-test was used for comparison of normally distributed continuous data before and after treatment within each group， and the independent-samples t test was used for comparison between groups； the Wilcoxon signed-rank test was used for comparison of non-normally distributed continuous data before and after treatment within each group， and the Mann-Whitney U test was used for comparison between groups. The chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups， and the Spearman test was used for correlation analysis. ResultsAfter CA280 treatment， the ACLF patients had significant reductions in the levels of cytokines （IL-6， IL-8， IL-10， TNF-α， and IFN-γ）， liver function parameters （ALT， AST， ALP， TBil， DBil， Alb， and glutathione reductase）， and the renal function marker urea nitrogen （all P<0.05）， and in terms of coagulation function parameters， there were significant increases in prothrombin time， activated partial thromboplastin time （APTT）， thrombin time， and international normalized ratio （INR） and significant reductions in prothrombin activity （PTA） and fibrinogen （FIB） （all P<0.05）. Compared with the DPMAS+LPE group， the CA280+LPE group showed better improvements in the serum cytokines IL-8 （Z=-2.63， P=0.009）， IL-10 （Z=-3.94， P<0.001）， and TNF-α （Z=-1.53， P=0.023）， and the two artificial liver support systems had a similar effect in improving liver function （ALT， AST， GGT， GR， TBil， and DBil） （all P >0.05）， but the CA280+LPE group showed a significantly greater reduction in Alb （Z=-2.08， P=0.037）. CA280+LPE was more effective in reducing uric acid （Z=-2.97， P=0.003）. Compared with DPMAS+LPE， CA280+LPE treatment resulted in a significant reduction in INR （Z=-4.01， P<0.001）， a significant increase in APTT （Z=-2.53， P=0.011）， and significant greater increases in PTA （Z=-6.28， P<0.001） and FIB （Z=-3.93， P<0.001）. There were no significant differences in the incidence rates of adverse reactions and the rate of improvement at discharge between the two groups （all P>0.05）. The Spearman correlation analysis showed that IL-6 was significantly correlated with WBC （r=0.22， P=0.042）， TBil （r=0.29， P=0.005）， and FIB （r=-0.33， P=0.003）； IL-8 was positively correlated with APTT （r=0.37， P<0.001） and INR （r=0.25， P=0.013）； TNF-α was significantly correlated with WBC （r=0.40， P<0.001） and TBil （r=0.34， P<0.001）. ConclusionCompared with DPMAS， CA280 combined with LPE can effectively clear proinflammatory cytokines and improve liver function in ACLF patients， but it has a certain impact on Alb and coagulation function. This regimen provides a new option for the individualized treatment of ACLF and can improve the short-term prognosis of patients， but further studies are needed to verify its long-term efficacy.

Objective:To investigate the clinical characteristics of first-episode and recurrent acute hypertriglyceridemic pancreatitis (HTGP).Methods:The retrospective cohort study was con-ducted. The clinical data of 313 patients with HTGP admitted to 26 medical centers in China in the Chinese Acute Pancreatitis Clinical Research Group (CAPCTG)-PERFORM database from November 2020 to December 2021 were collected. There were 219 males and 94 females, aged 38(32,44)years. Of the 313 patients, 193 patients with first-episode HTGP were allocated into the first-episode group and 120 patients with recurrent HTGP were allocated into the recurrent group. Observation indica-tors: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) comparison of severity and prognosis in the course of disease within 14 days between the two groups; (3) the association between recurrent HTGP and the risk of persistent organ failure (POF); (4) follow-up. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Wilcoxon rank sum test. Count data were expressed as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the Wilcoxon rank sum test. The Kaplan-Meier method was used to plot the cumulative recurrence rate curve and Log-Rank test was used for survival analysis. The Logistic regression model was used for multivariate analysis, and continuous variables were converted into categorical variables according to the mean value or common criteria. Propensity score matching was performed by 1∶1 nearest neighbor matching method, with caliper value of 0.02. Paired t test or Wilcoxon rank sum test and McNemar′s test were used for comparison between matched groups. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of the 313 patients,208 cases were successfully matched, including 104 cases in the first-episode group and 104 cases in the recurrent group. After propensity score matching, there was no significant difference in demographic characteristics, severity of illness scores and laboratory test between the two groups ( P>0.05). The elimination of gender, acute physiology and chornic health evaluation (APACHE) Ⅱ score, computed tomography severity index score, systemic inflammatory response syndrome score, sequential organ failure assessment score, apolipoprotein E, C-reactive protein, creatinine, lactic acid dehydrogenase, procal-citonin confounding bias ensured comparability between the two groups. (2) Comparison of severity and prognosis in the course of disease within 14 days between the two groups. There were signifi-cant differences in POF and local complications between the first-episode group and the recurrent group ( P<0.05). (3) The association between recurrent HTGP and the risk of POF. Results of uncor-rected univariate analysis showed that there was no association between recurrent HTGP and the risk of POF ( odds ratio=0.78, 95% confidence interval as 0.46-1.30, P>0.05). Results of multivariate analysis after adjusting for covariates such as gender, age, APACHE Ⅱ score, C-reactive protein, triglyceride and total cholesterol showed that compared with first-episode HTGP, recurrent HTGP was associated with a higher risk of POF ( odds ratio=2.22, 95% confidence interval as 1.05-4.71, P<0.05). Results of subgroup analysis showed that age<40 years was associated with an increased risk of POF ( odds ratio=3.31, 95% confidence interval as 1.09-10.08, P<0.05). (4) Follow-up. Twelve of the 313 patients died during hospitalization, including 9 cases in the first-episode group and 3 cases in the recurrent group. The rest of 301 surviving patients, including 184 cases in the first-episode group and 117 cases in the recurrent group, were followed up for 19.2(15.5, 21.9)months. Results of follow-up showed that for 184 survived patients of the first-episode group, 164 cases were followed up and 24 cases experienced recurrence, for 117 survived patients of the recurrent group,29 cases experienced recurrence, showing a significant difference between the two groups ( χ2=4.67, P<0.05). Conclusion:Compared with first-episode HTGP, patients with recurrent HTGP are more prone to POF and local complications, and are more prone to recurrence after discharge. The risk of POF in recurrent HTGP patients is 2.22 times that of those with first-episode, and the risk is higher in patients with age <40 years.

Objective:To evaluate the influence of a moisturizer containing oat kernel oil for xeroderma and water content of the stratum corneum in children.Methods:From September to December 2022, 30 children with xeroderma were treated in the Dermatology Department of Tongzhou Maternal and Child Health Hospital of Beijing; 13 were males and 17 were females, and the age was 7.33±2.63 years. This was a single-center self-controlled trial. All children applied the moisturizer on the dry skin of the bilateral limbs two time per day for 14 days, and were followed up at 7 days and 14 days. Efficacy was evaluated according to the water content of the stratum corneum, visual scale, xerosis severity scale (XSS), Specified Symptom Sum Score (SRRC), Visual Analog Scale (VAS) and so on. and side-reactions were recorded.Results:After application of the moisturizer, the median of water content in the stratum corneum was 49.00 (33.83, 87.25), 48.84 (32.58, 100.34) at 7 d and 14 d respectively, showing significant increases compared with that at baseline (median 26.51 (16.00, 47.75) ( Z=-3.075, Z=-2.911, P<0.01). The visual scale, XSS, SRRC and VAS showed that compared with the baseline at 7 d, 14 d, the skin dryness and pruritus scores improved significantly ( Z=-4.424, -4.150, -3.943, -4.400; Z=-4.744, -4.409, -4.260, -4.409, P<0.01). Conclusions:The application of this moisturizer containing oat kernel oil could effectively improve skin dryness and the water content of the stratum corneum without serious adverse reactions.

Obesity is a chronic， recurrent， and progressive metabolic disorder characterized by the abnormal or excessive accumulation of body fat caused by multiple factors such as genetics， dietary structure， lifestyle and behavior， psychology， environment， and society， leading to an energy surplus. Obesity is a major risk factor that increases the risk of developing various chronic diseases， including type 2 diabetes， hypertension， cardiovascular diseases， stroke， and certain malignancies. The global incidence of obesity is increasing year by year. With the continuous improvement of people's living standards， more than half of adults in China are now overweight or obese， posing a serious threat to people's health and increasing the social and economic burden. It has become a pressing major public health issue that needs to be addressed urgently. The concept of obesity can be traced back to the Huangdi’s Internal Classic （Huang Di Nei Jing）， which describes it as "the problems in fat and affluent people are caused by excessive taking of rich food"， and suggests that ''frequent intake of rich and greasy foods can produce interior heat. Sweet flavor causes chest fullness. That is why its spleen-Qi flows upwards and changes into consumption-thirst disease. It can be treated by Eupatorii Herba which is used to remove stagnant Qi''. The stagnant qi is caused by the transformation failure of rich and greasy food and wine， so obesity is the disease of stagnant qi. Obesity is caused by indulging in rich and greasy food， wine， spicy and flavorful foods， raw and cold foods， and sweet and greasy foods， or overeating and leading a sedentary lifestyle， staying up late， or experiencing emotional imbalances such as excessive joy， anger， worry， pensiveness， and fear. It can also be caused by congenital abnormalities， leading to improper functioning of the spleen and stomach， dysregulation of the absorption and secretion of the small intestine， and the accumulation of stagnant Qi in the organs and muscles， resulting in a plump physique. The intake of food and drink depends on the functions of the stomach in receiving and decomposing， the small intestine in absorbing and secreting， and the spleen in transforming and transporting. The affected organs in obesity are the spleen， stomach， and small intestine. Orchids， specifically Eupatorii Herba and Lycopi Herba， are aromatic herbs that can regulate the smooth flow of Qi， eliminate stagnation， and cleanse impurities. In a broader sense， any aromatic and pungent substance that can invigorate the spleen， promote clarity， harmonize the stomach， reduce turbidity， and assist in the normal secretion and absorption functions of the small intestine， thereby eliminating excess， is referred to as orchid. Therefore， the treatment principle for obesity is to use ''orchids to eliminate stagnant Qi''， aiming to regulate the functions of the spleen， stomach， and small intestine using aromatic and pungent substances， gradually eliminating excessive dampness， phlegm， turbidity， and heat， and restore the balance of the middle energizer. This way， individuals who are obese can achieve a non-obese state.

Objective:To investigate the clinical pathological and epidemiological characteristics of primary esophageal malignant melanoma (PMME).Methods:The clinical pathology data of 180 PMME patients in the esophageal cancer database of the key laboratory of esophageal cancer research in Henan Province from 1973 to 2016 were collected, of which 136 were male, aged (58.5±9.0) years, 44 were female, aged (56.7±12.2) years. Kaplan-Meier and Log rank test were used for survival analysis, Cox regression scale model was used for risk factor analysis.Results:The incidence of PMME is 0.036% (180/500, 000), mostly were male (about 3∶1 for men: female). The common sites of PMME were the lower part of the esophagus (48.9%, 85/174), followed by the middle section of the esophagus (46.0%, 80/174) and the upper part of the esophagus (5.2%, 9/174). No black particles were seen in the PMME cells of 3 patients under microscope, and strong positive expressions of Melan-A and HMB453 were observed in these 3 patients by immunohistochemical results. Of the 129 patients who had a routine preoperative esophageal biopsy, 69 were undiagnosed with PMME (53.5%). The medium survival time of the whole group was 7.9 months, and the survival rates of 1, 2, 3, 5 years were 25.0%, 7.9%, 6.6% and 1.3%, respectively. The univariate analysis showed that N, M, TNM phase and radiotherapy were related to the overall survival of patients ( P<0.05). Multivariate analysis showed that TNM phase and radiotherapy were the independent risk factors for overall survival of patients ( P<0.05). Conclusions:PMME is more common in men, the common site of the disease is the lower part of the esophagus. The preoperatively missed diagnosis rate of Chinese PMME is high. TNM phase and radiotherapy are the independent risk factors for overall survival of patients.

Objective To analyze the relationship between BMI, physical activity, resting heart rate and diabetes mellitus. Methods A total of 423 patients with diabetes admitted to the Department of endocrinology of our hospital from August 2017 to August 2020 were investigated by questionnaire and physical signs were examined, and the correlation between BMI, physical activity, resting heart rate and diabetes was analyzed. Results FPG, 2 h PG and HbA1c were positively correlated with resting heart rate, BMI and physical activity (P < 0.05). Multiple logistic regression analysis showed that BMI (OR = 2.121), elevated resting heart rate (OR = 1.619) and less physical activity (OR = 0.711) were risk factors for diabetes. Conclusion The increase of BMI and resting heart rate and the decrease of physical activity will increase the risk of diabetes. It is particularly important to prevent the increase of BMI and resting heart rate and increase the physical labor appropriately.

Objective:To investigate the clinicopathological characteristics and the risk factors of lymph node metastasis(LNM) of undifferentiated early gastric cancers(EGCs) in elderly patients.Methods:The elderly patients(≥65 years old) who underwent radical gastrectomy with lymph node dissection and were diagnosed as having EGCs in Peking Union Medical College Hospital from January 2010 to August 2019 were included. The clinicopathological characteristics of undifferentiated EGCs(namely signet ring cell EGCs and poorly differentiated EGCs) were compared with those of differentiated EGCs, and the risk factors for LNM of undifferentiated EGCs in the elderly patients were analyzed with logistic regression.Results:Data of 165 elderly EGCs patients were reviewed, including 82 undifferentiated EGCs (11 signet ring cell and 71 poorly differentiated) and 83 differentiated EGCs. The overall LNM incidence was 9.1% (15/165) in elderly EGCs patients, 4.8% (4/83) and 13.4% (11/82) in differentiated and undifferentiated EGCs, respectively. Of all undifferentiated EGCs, the LNM incidence in poorly differentiated EGCs was 15.5%(11/71), and none of 11 signet ring cell EGCs had LNM. Depth of tumor invasion( P=0.019), tumor size( P=0.006), combination of ulceration( P=0.006), depressed gross type( P=0.003) were found to be associated with LNM in elderly undifferentiated EGCs patients under univariate analysis. Multivariate analysis revealed that submucosal invasion( OR=11.98, 95% CI: 1.17-122.84, P=0.037) and tumor size >2 cm ( OR=11.95, 95% CI: 1.88-76.07, P=0.009) were independent risk factors for LNM in elderly undifferentiated EGCs patients. All elderly undifferentiated EGCs patients who met the criteria for expanded indications had no LNM. Conclusion:Submucosal invasion and tumor size >2 cm are independent risk factors for LNM in elderly undifferentiated EGCs patients. The elderly EGCs patients who met the criteria for expanded indications are suitable for endoscopic submucosal dissection.

Objective:To explore the clinical effects of simultaneous reconstruction of multiple joint scar contracture deformity of limb.Methods:From January 2010 to June 2018, 24 patients with multiple joint scar contracture deformity of the same limb were reconstructed in simultaneous operations in Xiangya Hospital of Central South University, including 16 males and 8 females, aged 3-42 years, with 15 patients having deformities in the upper limbs and 9 patients having deformities in the lower limbs. One operation was performed to repair contracture deformity of axillary fossa and elbow in 3 patients, cubital fossa and palmar of wrist in 4 patients, cubital fossa and hand in 5 patients, palmar of wrist, palm, and palmar of finger in 3 patients, groin and medial knee in 2 patients, popliteal fossa and posterior ankle in 1 patient, and anterior ankle and dorsum of foot in 6 patients. After the release of various joint scar contractures, the area of skin defect was 140 to 580 cm 2. Autologous full-thickness skin grafts were used in 7 patients, autologous medium-thickness skin grafts were used in 4 patients, autologous full-thickness skin grafts combined with local skin flaps were used in 9 patients, and allogeneic acellular dermal matrix and autologous thin skin grafts were used in 4 patients. Comprehensive measures for rehabilitation were taken and the survival of the skin graft was observed after operation. Six months to eight years after the operation, all the patients were followed up for the functions of the affected limbs, among which the functions of the upper limbs were evaluated according to the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association. The joint mobility, walking, and squatting function of lower extremity were examined after operation. Recurrence of contractures in all the affected limbs and reoperation were recorded. Results:The grafts survived after operation in 22 patients. Two patients had necrosis in small full-thickness skin area, of which one was healed by skin grafting after debridement, and the other one was healed after dressing changes. The deformity of scar contracture at each repaired joint was completely or partially corrected. During a follow-up for 6 to 96 months, the upper limb functions of 15 patients were rated excellent in 12 patients and good in 3 patients. Among the 9 patients of lower limb scar contractures, except for one 3-year-old child who experienced recurrence of medial knee scar contracture and underwent surgical release and skin grafting 5 years later, the remaining 8 patients basically recovered normal joint functions with pretty good outcomes.Conclusions:For continuous scar contracture deformity of multiple joints of the same limb, simultaneous surgical release and skin grafting can reduce operation frequency and obtain better outcomes of surgical operation.
