Objective: To explore the effectiveness of machine learning algorithms in predicting non-suicidal self-injury (NSSI) behavior among college students, and to analyze the influencing factors of NSSI behavior, thus providing a reference for promoting psychological well-being. Methods: In December 2022, a stratified random cluster sampling method was used to select 835 college students from a university in Guizhou Province, China. The Adolescent Self-injury Scale, Family Function Assessment Scale, and Emotion Regulation Self-efficacy Scale were used to evaluate the participants. Demographic characteristics, family factors, and emotional factors were taken as independent variables, while the dependent variable was whether college students exhibited NSSI behavior. Machine learning algorithms, including Logistic regression, support vector machine (SVM), decision trees, algorithm gradient boosting trees, random forests, and AdaBoost, were used to construct predictive models. Results: The detection rate of NSSI behavior among the college students was 23.23% (194 individuals). The NSSI behavior group scored higher than the non-NSSI behavior group in total family function, emotional communication, egoism, and family rules ( t=3.02, 3.35 , 2.23,2.87, P <0.05). On the other hand, the non-NSSI behavior group scored higher than the NSSI behavior group in total emotion regulation selfefficacy, managing negative emotion self-efficacy, and expressing positive emotion self-efficacy ( t=-5.04, -5.48 , -2.43, P <0.05). The recall rates of random forests, SVM, Logistic regression, decision trees, algorithm gradient boosting trees, and AdaBoost were 84.3% , 90.6%, 73.4%, 87.5%, 95.3%, 89.0%, respectively. The F1 scores were 84.4%, 92.1%, 71.2 %, 79.4%, 91.7%, 89.1% , respectively. The respective precision rates were 84.4%, 93.5%, 69.1%, 72.7%, 88.4%, 89.1 %. The AUC scores were 0.845, 0.922, 0.706, 0.776, 0.915, and 0.891, respectively. Conclusion Compared to the algorithm gradient boosting tree, random forest, Logistic regression, and AdaBoost models, the SVM model has a better predictive effect on whether college students in Guizhou Province exhibits NSSI behavior. It is recommended to use an appropriate model to identify students at risk of NSSI behavior as early as possible and provide psychological crisis interventions to promote their mental health.

Objective To investigate the effect of MDM2 inhibitor RG-7388 on the proliferation, cell cycle, and apoptosis of diffuse large B-lymphoma (DLBCL) cells. Methods DLBCL cell strains SUDHL2 and HBL1 were treated with 2, 4, and 8 μmol/LRG7388, respectively. Cell proliferation was detected by CCK8 and EdU methods. Apoptosis was measured by Annexin V–FITC/PI double staining and Caspase 3/7-Glo enzyme activity methods. Cell cycle was assessed by flow cytometry. Changes in the expression of cell cycle and apoptosis-related proteins were determined by Western blot. Results The IC₅₀ of RG7388 for inhibiting SUDHL2 and HBL1 cells were 3.36 and 3.76 μmol/L, respectively, and the inhibitory effect of RG7388 was dose dependent. The proportions of G₁ phase and apoptotic cells in the SUDHL2 and HBL1 cells treated with different doses of RG7388 were significantly higher than those in the control group (all P<0.05). The activity of Caspase 3/7 increased gradually with RG7388 concentration, compared with that in the control group. The expression levels of p53, p27, p21, and PARP increased, whereas the expression of Mcl-1 and Bcl-x_L was down-regulated (all P<0.05). Conclusion MDM2 inhibitor RG-7388 inhibits the proliferation of DLBCL cells, triggers cell cycle arrest in the G₁ phase, and induces apoptosis through the p53 pathway.

Two researchers independently screened the literature, extracted the data, and evaluated the quality of the literature using Newcastle-Ottawa Scale (NOS) . Stata 15.0 statistical software was used to conduct a Meta-analysis of the included literatures.Results:A total of 19 articles were included, including 5 295 patients. The Meta-analysis results showed that the combined odds ratio ( OR) values and 95% confidence interval (95% CI) of various factors for postoperative delirium in colorectal cancer patients were advanced age [1.10 (1.06-1.14) ] , male [2.29 (1.81-4.44) ] , alcohol abuse [3.14 (1.63-6.06) ] , preoperative physical condition grading (≥level 3) [1.47 (1.13-1.91) ] , comorbidities [1.59 (1.16-2.17) ] , history of mental illness [7.86 (4.57-13.54) ] , history of cerebrovascular disease [5.74 (3.78-8.72) ] , cognitive impairment [3.31 (1.20-9.08) ] , albumin [0.81 (0.66-0.99) ] , perioperative blood transfusion [2.29 (1.41-3.69) ] and C-reactive protein [2.24 (1.11-4.53) ] , all P<0.05. Conclusions:The risk factors for delirium in colorectal cancer patients after operation are old age, male, alcoholism, preoperative physical condition grading≥level 3, combined diabetes and other basic diseases, history of mental disease, history of cerebrovascular disease, cognitive dysfunction, low albumin, perioperative blood transfusion and elevated C-reactive protein.

Liddle syndrome and Gordon syndrome are two rare single-gene inherited hypertension diseases. In patients≤40 years, the prevalence of Liddle syndrome is about 1% and Gordon syndrome is uncertain all over the word, for which is often misdiagnosed and mistreated. The therapies of those diseases are targeted at gene mutation sites, as well as combined with modified lifestyle, and can achieve satisfactory diseases control. This paper reports a patient who is diagnosed with Liddle syndrome and Gordon syndrome at the same time. We aimed to consolidate and improve the diagnosis and accurate treatment of those two diseases by sharing, studying and discussing together with clinical doctors.

Objective:To access the clinical efficacy and safety of hydroxychloroquine (HCQ) in treatment of IgA nephropathy (IgAN).Methods:The data of IgAN patients who were diagnosed by renal biopsy in the First Affiliated Hospital, College of Medicine, Zhejiang University from May 2016 to August 2020 and had been treated with HCQ for more than 6 months without other immunosuppressants were retrospectively analyzed. The efficacy and side effects were compared between groups according to the baseline urine protein/creatinine ratio (UPCR) or whether combined with renin-angiotensin-aldosterone system inhibitor (RAASi).Results:A total of 121 patients were enrolled, including 45 males (37.19%). At baseline, the median UPCR was 0.69(0.45, 1.00) g/g; the median estimated glomerular filtration rate (eGFR) was 93.46(73.14, 115.67) ml·min -1·(1.73 m 2) -1; the median serum creatinine was 80.00(61.00, 98.00) μmol/L, and the serum albumin was (44.39±3.36) g/L. After HCQ treatment, UPCR and red blood cells were significantly decreased compared with baseline (all P<0.05). Triglyceride, total cholesterol and low-density lipoprotein cholesterol were also significantly decreased during the follow-up period. Serum creatinine, eGFR, serum albumin and serum uric acid remained stable. After 6 months of follow-up, the total remission rate was 56.88%, including 15.60% of partial remission and 41.28% of complete remission; at the end of follow-up, the median follow-up time was 280.00(214.00, 411.00) days and the total remission rate was 56.20%, including 9.92% of partial remission and 46.28% of complete remission. Group analysis showed that the remission rate was 60.53% ( n=76) and 48.48% ( n=33) at 6 months (Mann-Whitney U test, Z=-2.331, P=0.020) and 57.65% ( n=85) and 52.78% ( n=36) at the end of follow-up (Mann-Whitney U test, Z=-1.673, P=0.094) between patients with baseline UPCR<1 g/g and patients with baseline UPCR≥1 g/g; and the remission rate was 66.67% ( n=30) and 53.16% ( n=79) at 6 months (Mann-Whitney U test, Z=1.062, P=0.288) and 61.29% ( n=31) and 54.44% ( n=90) at the end of follow-up (Mann-Whitney U test, Z=0.930, P=0.352) between patients with single HCQ and patients with HCQ+RAASi. For side effects, the eGFR of 2 patients decreased by more than 30% compared with baseline, 1 patient relapsed and 1 patient developed blurred vision. Conclusions:HCQ is safe and effective for the treatment of IgAN.

Objective:To evaluate the efficacy of bupivacaine pamoate for sciatic nerve block in rats.Methods:Forty-eight SPF healthy male Sprague-Dawley rats, weighing 300-400 g, were divided into 6 groups using a random number table method: bupivacaine pamoate vehicle group (group VE), bupivacaine HCl group (group BH), liposomal bupivacaine group (group BL), low-dose bupivacaine pamoate group (group HL), moderate-dose bupivacaine pamoate group (group HM) and high-dose bupivacaine pamoate group (group HH), with 8 animals in each group.In VE, BH, BL, HL, HM and HH groups, bupivacaine pamoate vehicle 0.4 ml, bupivacaine HCl solution 0.4 ml, liposomal bupivacaine suspension 0.4 ml, and 1, 3 and 10 mg/ml bupivacaine pamoate suspension 0.4 ml were injected around the left sciatic nerve, respectively.The thermal paw withdrawal latency were measured before administration (T 0) and at 0.5, 1.5, 3, 5, 8, 12, 16, 24 and 48 h after injection (T 1-9). The percentage of maximum possible effect (MPE) of thermal paw withdrawal latency was calculated, and motor function score was simultaneously performed to evaluate the efficacy of sensory and motor block.Five and three rats in each group were sacrificed at 2 and 7 days after administration (T 9, 10), respectively, and the sciatic nerve at the injection site and the surrounding muscle tissues were harvested for microscopic examination (with a light microscope) after Luxol fast blue and HE staining.Nerve damage and inflammatory responses were assessed and scored to evaluate neurotoxicity. Results:Compared with group VE, the MPE was significantly increased at T 1-4 in group HL, at T 1-8 in group HM and at T 1-8 in group HH, the motor function scores were decreased at T 1-4 in group HL, at T 1-5 in group HM and at T 1-7 in group HH ( P<0.05), and no significant change was found in inflammatory response scores for the sciatic nerve and surrounding muscles at each time point in HL, HM and HH groups ( P>0.05). Compared with group BH, the MPE was significantly increased at T 3-8, motor function scores were decreased at T 3-5, and inflammatory response scores for the muscles around the sciatic nerve were decreased at T 9 in group HM ( P<0.05). Compared with group BL, the MPE was significantly increased at T 3-7, motor function scores were decreased at T 4, 5, and inflammatory response scores for the sciatic nerve and surrounding muscles were decreased at T 9 in group HM ( P<0.05). The nerve damage score was 0 in the six groups. Conclusion:Bupivacaine pamoate can block the sciatic nerve of rats, the duration of block is prolonged with the increase in the concentration, and the duration of motor block is not longer than that of sensory block; compared with the same concentration and equal volume of bupivacaine HCl and liposomal bupivacaine, bupivacaine pamoate produces longer duration of sciatic nerve block and less neurotoxicity.

Objective:To describe the status and influencing factors of nurse-related empowerment perception in inpatients with chronic diseases.Methods:Totally 586 inpatients with chronic diseases from 6 class A hospitals in Shanghai from November 2019 to September 2020 were investigated by the Chinese version of Patient Perception of Patient-empowering Nurses Behaviors (PPPNBS), Self-Efficacy of Chronic Diseases (SECD6), Nurse-patient Trust Scale (NPTS), Chinese version of Chronic Illness Resource Survey (CV-CIRS) and a general information questionnaire which was designed by researchers.Results:The total score of PPPNBS was (134.98 ± 59.60) points, and the average score for each item was (6.14 ± 2.71) points. The total score of SECD6 was (38.81 ± 9.28) points. The total score of NPTS was (141.94 ± 11.42) points, and the total score of CV-CIRS was (57.90 ± 15.24) points, which were positively correlated with empowerment perception through Pearson correlation analysis. Multiple Linear Regression showed that the degree of education, the number of forms and compliance of health education, the times of admission, participation intention in medical decision-making, the dimension of Symptom Management in Self-efficacy, three dimensions of consistency, respect, and confidence in knowledge and technology in Nurse-Patient Trust degree and four dimensions of medical staff support, organization support, family and friends support, media and government support in Chronic Illness Resource were influencing factors of patients ′ empowerment perception (adjusted R 2 value was 0.636, F value was 79.441, P<0.01). Conclusions:Compared with the foreign level, the perception of nurses ′ empowerment of inpatients with chronic diseases is at a lower level, and self-efficacy, nurse-patient trust and chronic disease resource support are all at a medium level, which still need to be improved. Nurses should allow them to participate in their treatment, improve the control of life and reduce their anxiety.

We report a case of a 2 200 g premature male baby born through cesarean section under maternal endotracheal intubation mechanical ventilation combined with extracorporeal membrane oxygenation at 34 +1 gestational weeks, while his mother was infected with influenza A in late pregnancy. Due to neonatal pneumonia, neonatal respiratory distress syndrome, prematurity, and low birth weight, the neonate was transferred to the neonatal intensive care unit for body temperature maintenance, respiratory support, maintenance of perfusion and internal environment, and nutritional management. The infant was discharged 17 days after birth and was well at six-month-old follow-up. His mother was discharged at 20 days post-delivery.

Objective:To explore the mediating effect of children's effortful control on the relationship between home environment and children's behavioral emotional problems in preschool children with malignant tumors and to provide evidences for family intervention on behavioral emotional problems in children.Methods:Totally 353 preschool children with malignant tumors were investigated with family adaptation and cohesion evaluation scales II (FACES II), child behavior questionnaire-very short form(CBQ-VSF) and strengths and difficulties questionnaire (SDQ), AMOS 22.0 software was used to construct a structural equation model in data analysis and the Bootstrap method was used to test the mediation effect.Results:The scores of family adaptation and cohesion, children's effortful control, difficulty questionnaire were(51.63±12.41), (55.43±10.16), (3.23±0.80) and (13.75±3.66). The scores of dimensions including emotion, conduct, hyperactivity, peer problems, prosocial of difficulty questionnaire were(2.83±0.90), (2.73±0.96), (2.67±0.93), (2.76±0.85), (2.67±0.85), respectively. Family adaptation and cohesion were positively correlated with children's effortful control ( r=0.244, 0.289, P<0.01). Children's effortful control was negatively correlated with children's behavioral emotional problems ( r=-0.365--0.302, all P<0.05). Family adaptation and cohesion were negatively correlated with children's behavioral/emotional problems ( r=-0.323--0.124, r=-0.342--0.181, all P<0.05). The direct effect value was -0.469, indirect effect value was -0.102, accounting for 17.86% of the total effect. Conclusion:Children's effortful control exert a significant mediating effect on the relationship between home environment and children's behavioral/emotional problems in preschool children with malignant tumors, suggesting that medical staff should pay attention to the level of effortful control of preschool children with malignant tumors in order to take effective actions to reduce children's behavioral/emotional problems and improve social applicability.
