Objective This study assesses a feasible and safe volume threshold for chest tube removal following a VATS lobectomy.Methods The study included 168 consecutive patients who underwent VATS lobectomy or bilobectomy with two insicion between August 2012 and February 2014.Eligible patients were randomized into 3 groups:Group A (chest tube removal at the drainage volume of 150 ml/d or less.n =49) ; Group B (chest tube was removed when the drainage volume was less than 300 ml/d.n =50) ; Group C(chest tube removal when the drainage was less than 450 ml/d.n =51).And there were 18 patients who were excluded.All patients got the same postoperative care with a clinical pathway,and all patients were followedup 7 days after discharge from hospital.The time of extracting drainage tube,postoperative hospital stay,postoperative VAS values,dosage of analgesic,incidence of complications and thoracocentesis were measured.Results There were no statistically significant differences among 3 groups with general information and incidence of complication (P ＞ 0.05).And there were statistically significant differences between Group A and Group B with the time of extracting drainage tube,postoperative hospital stay,postoperative VAS values,dosage of analgesic(P ＜ 0.05).But there were no statistically significant differences between Group A and Group B with incidence of thoracocentesis(P ＞0.05).Analysis of data showed no statistically significant differences between Group B and Group C with postoperative hospital stay,postoperative VAS values and dosage of analgesic (P ＞ 0.05),but there were statistically significant differences for incidence of thoracocentesis (P ＜ 0.05).Conclusion A 300 ml/d volume threshold for chest tube removoal after VATS lobectomy is feasible and safe,and it can bring more advantages than the 150 ml/d volume threshold.On the other hand,a 450 ml/d volume threshold for chest tube removoal after VATS lobectomy may increase the risk of thoracocentesis.

OBJECTIVETo investigate the feasibility of a new mode to diagnose and treat intrathoracic gastroesophageal anastomotic leak.

METHODSFrom January 2007 to December 2014, fifty-five patients were confirmed intrathoracic gastroesophageal anastomotic leak among those were performed surgical operation due to esophageal or cardiac carcinoma in the First Affiliated Hospital of Soochow University. To retrospectively analyze the clinical data of these patients, thirty-six male and nineteen female were included with the ages from 49 to 81 years (average age of (67±6)years). Among them, forty-two were middle esophageal carcinoma, eleven were lower esophageal carcinoma and two were cardiac carcinoma. According to the differences of diagnosis and treatment methods for anastomotic leak, fifty-five patients were divided into two groups. Thirty-one patients distributed from January 2007 to November 2011 were received conventional management (conventional group): to definitively diagnose by contrast swallow when suspected to be developing anastomotic leaks, to place an esophageal stent when the drainage was sufficient and the infection was controlled. Twenty-four patients distributed from March 2011 to December 2014 were received new-mode management (new-mode group): to perform a anastomotic radioscopy under digital subtraction angiography -guidance instantly when suspected anastomotic leak and find out the fistula, search the shape and size, place a drainage tube into the fistula to drain or lavage the vomica according to the exploration results, pull back the tube gradually and close the leak by clips under endoscope later. The pathoclinical features, the confirmation time (time from clinical signs emergence to leak confirmation), the hospital duration after confirmation, the incidence of severe complications and total mortality were compared between the two groups by t-test and χ(2) test or Fisher's exact test.

RESULTSThere was no significant statistical differences in pathoclinical features between two groups (P>0.05). The confirmation time was significantly reduced in new-mode group than that in conventional group ((1.2±0.8) d vs. (3.6±2.2) d, t=5.212, P=0.000), and so was the hospital duration after confirmation ((26±12) d vs. (55±25) d, t=4.992, P=0.000) and the incidence of severe complications (16.7% vs. 48.4%, χ(2)=6.019, P=0.014), although there was no statistical differences in total mortality (4.2% vs. 22.6%, P=0.119).

CONCLUSIONThe new mode of early interventional diagnosis, early fistula drainage through nose and clipping under endoscope later is able to shorten diagnosis and treatment period, reduce incidence of severe complications.

Objective:To investigate the association of metabolic syndrome(MS) with cardiovascular disease(CVD) mortality and all-cause mortality in peritoneal dialysis patients.Methods:A retrospective analysis was performed on patients who underwent peritoneal dialysis from January 1, 2013 to July 31, 2021 in the Shaoxing People′s Hospital. Patients were divided into MS group and non-MS group. The differences in baseline biochemical variables, comorbidities, and clinical outcomes between the two groups were compared. Kaplan-Meier method was used to obtain survival curves, the Cox regression model was used to evaluate the influence of MS for survival rates, and the inverse probability of treatment weighting(IPTW) was used to eliminate influence of the confounders in the groups.Results:A total of 494 peritoneal dialysis patients were enrolled in this study, which were divided into MS group( n=266) and non-MS group( n=228). The total median follow-up time was(31±22) months. At baseline, the standard mean difference( SMD) in smoking history, drinking history, CVD history, prevalence of chronic glomerulonephritis, left ventricular ejection fraction, B-type natriuretic peptides, hemoglobin, blood calcium, hypersensitive C-reactive-protein, intact parathyroid hormone, ultrafiltration and 4 h dialysate/plasma creatinine in the two groups were greater than 0.1. Their SMD decreased to under 0.1 after IPTW, showing a good balance between the two groups. The analysis of the survival curve of Kaplan Meier showed that the cumulative survival rate and cumulative CVD survival rate in MS group were significantly lower than those in non-MS group before and after IPTW( P<0.05). After IPTW was used to eliminate the effect of confounders, multivariate Cox regression analysis still displayed that MS was an independent risk factor for all-cause mortality( HR=1.824, 95% CI 1.121-2.968, P=0.015) and CVD mortality( HR=2.470, 95% CI 1.324-4.609, P=0.004)in peritoneal dialysis patients. Conclusion:The prevalence of metabolic syndrome is high in peritoneal dialysis patients. MS is an independent risk factor for all-cause mortality and CVD mortality in peritoneal dialysis patients.

Objective: To explore the current status related to behavioral problems among children and adolescents aged 12-16 years old in Guizhou Province, China, and to provide a reference for timely prevention and intervention measures. Methods: To capture different economic development levels, a multistage stratified cluster sampling method was used. A total of 3 217 children and adolescents aged 12-16 years old from six middle schools and six primary schools in Guiyang, Duyun, Kaili City from Guizhou Province participated in this study. The Achenbach Child Behavior Checklist (CBCL) and a self designed questionnaire were administered between August and December 2021. Results: The overall detection rate of behavioral problems among the students was 16.60% , and the rate was 14.41% and 18.62% among male and female students, respectively. The results of the Logistic regression analysis showed that good peer relationships ( OR=0.25, 0.16, P <0.05) were associated with a lower risk of behavioral problems in children and adolescents. However, the following factors were associated with an elevated risk of behavioral problems: nonparents as the main caregivers( OR = 1.44 ); children s daily screen time was 1-2 h ( OR =1.47) or more than 2 h( OR =2.75); children who had no sports hobbies( OR = 1.36); father parenting for doting or neglect( OR =1.85, 2.01); maternal parenting for doting( OR = 2.12 ); father had bad life habits( OR =1.69); father and mother were occasionally sick( OR =1.30, 1.38)( P <0.05). Conclusion Behavioral problems among children and adolescents in Guizhou Province is related to children s unhealthy living habits and various factors in the family environment. It is suggested that families, schools and relevant functional departments give full play to their own advantages and take comprehensive measures to prevent the occurrence of behavioral problems among children and adolescents.

Objective: To investigate the relationships among psychological resilience, parental control, and behavioral problems in middle school students, aiming to provide evidencebased recommendations for the prevention and intervention of behavioral issues in middle school students, as well as for the development of related policies. Methods: A stratified cluster sampling method was used to select 2 745 participants from three cities in Guizhou Province with different levels of economic development from August to December 2021. The Child Behavior Checklist (CBCL), Parental Control Questionnaire, and Psychological Resilience Questionnaire were administered to junior high school students and their parents. A network analysis method was employed to construct a network analysis model of factors influencing behavioral problems. Results: The detection rate of behavioral problems among junior high school students in Guizhou Province was 22.62%. The scores for psychological resilience (goal focus, emotional control, positive cognition, family support, and interpersonal assistance) and proactive inquiry in behavior control were higher in the group without behavioral problems than in the group with behavioral problems. Scores for psychological control (inducing guilt, with drawing affection, and asserting authority) were higher in the group with behavioral problems than in the group without behavioral problems, with statistically significant differences (t=9.80, 17.76, 6.21, 12.20, 13.18, 6.28, 11.58, 11.10, 10.74, P<0.05). The network model showed that among the same variable factors, the strongest connection weight was between inducing guilt and withdrawing affection, with a weight of 0.79. Between different variables, there were negative correlation between behavioral problems and psychological resilience (goal focus, emotional control, positive cognition, family support, interpersonal assistance) and behavior control (proactive inquiry, behavioral restraint) with correlation coefficients (r=-0.25, -0.42, -0.16, -0.31, -0.33, -0.17, -0.03, P<0.05), respectively. There were positive correlation between psychological control factors (inducing guilt, withdrawing affection, and asserting authority) and behavioral problems (r=0.29, 0.27, 0.27), and a negative correlation between these psychological control factors and psychological resilience factors (goal focus, emotional control, positive cognition, family support, interpersonal assistance)(r=-0.53--0.13)(P<0.05). The strongest connection weight was between withdrawing affection and family support, with a connection weight of -0.53. Family support was an important bridge symptom connecting the entire behavioral problem network model, with a high centrality. Conclusions The detection rate of behavioral problems among junior high school students in Guizhou Province is relatively high. Assisting adolescents in establishing a supportive family environment facilitates the cultivation of their psychological resilience, thereby mitigating the occurrence of behavioral problems.

In the clinical settings, disseminated intravascular coagulation (DIC) and complications such as hemorrhage are commonly seen in acute promyelocytic leukemia patients, whereas thrombosis is rarely reported. We reported a case here that the patient presented with cerebral infarction as the first manifestation. During the admission, the patient encountered differentiation syndrome, pulmonary embolism, pulmonary hemorrhage, and myocardial ischemia, as well as bleeding and thrombosis complications. Hence the patient was diagnosed as DIC. After the treatment of blood transfusion instead of anticoagulation, his condition was stable and the remission was completely achieved. The treatment experience provides guides for other patients with similar complications of simultaneous bleeding and thrombosis.
