Objective: To explore the relationship between non suicidal self injury (NSSI) behavior and serum lipid levels as well as thyroid function among college students with depression. Methods: A total of 169 college students with depression in the psychiatry departments of tertiary hospitals (grade 3A and 3B) in Ningbo from December 2023 to April 2025 were selected. The Adolescent Self injury Scale (ASIS) was used to assess the presence of NSSI, and participants were accordingly divided into a NSSI group ( n =51) and a non NSSI group ( n =118). General demographic data (including gender, age, and family situation) were collected from both groups. Blood tests were performed to measure lipid profiles [triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C)] and thyroid hormones [triiodothyronine (T3), thyroxine (T4), free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH)]. Multivariate Logistic regression was employed to analyze risk factors for NSSI, and receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive value of serum lipid and thyroid hormone levels for NSSI occurrence in college students with depression. Results: The levels of TC, LDL-C, and TSH in the NSSI group were (4.02±0.73) mmol/L, (2.32±0.36) mmol/L, and (6.57±1.95) mU/L , which were significantly higher than those in the non NSSI group [(3.41±0.56) mmol/L, (2.00±0.27) mmol/L, and ( 4.48± 1.09) mU/L, respectively] ( t =5.32, 5.60, 7.20, all P <0.05). Logistic regression analysis revealed that college students from single parent/reconstituted families, those who had experienced school bullying, and those with higher levels of TC, LDL-C, and TSH had a significantly increased risk of engaging in NSSI ( OR =5.22, 6.12, 5.90, 83.64, 3.64, all P <0.05). ROC curve analysis demonstrated that the combined detection of TC, LDL-C, and TSH had high diagnostic efficacy for predicting NSSI in college students with depression, with a sensitivity of 86.3% and a specificity of 94.9%. Conclusions NSSI behavior in college students with depression is associated with serum lipid levels and thyroid function. These biomarkers may serve as useful reference indicators for assessing the conditions of these patients.

TCM believes that the main pathogenesis of gastrointestinal dysfunction (GD) after laparoscopic cholecystectomy (LC) is spleen and stomach weakness, liver and stomach disharmony, liver depression and spleen deficiency, and intestinal depression. Moxibustion in the treatment of GD after LC can avoid the aggravation of gastrointestinal burden caused by oral drugs. The intervention methods mainly include suspension moxibustion, umbilical moxibustion, heat sensitive moxibustion, thunder fire moxibustion, warm acupuncture, partition moxibustion, etc. Moxibustion is often performed on the acupoints in liver meridian, spleen meridian, stomach meridian, small intestine meridian, large intestine meridian and Conception Vessel, such as Taichong (LR3), Ganshu (BL18), Yinlingquan (SP9), Zusanli (ST36), Tianshu (ST25), Wangu (SI4), Hegu (LI4), Zhongwan (CV12), Shenque (CV8) and Qihai (CV6). At present, most studies combined with moxibustion on the basis of conventional Western medicine treatment can significantly improve the efficacy, and have certain advantages in improving gastrointestinal motility decline, intestinal flora imbalance, first exhaust time, gastrointestinal hormone level disorder and intestinal mucosal barrier dysfunction. However, there are still some problems in the existing research: small sample size of clinical research, not perfect scoring scale, not unified treatment plan and operation standard, relatively scarce basic research, relatively simple acupoint research, lack of biochemical evaluation indicators, and the research of national moxibustion needs to be explored and improved in the future.

AIM:To investigate the value of optical coherence tomography angiography(OCTA)indicators in the diagnosis of diabetic retinopathy(DR), and to provide patients with diabetic nephropathy(DN)with more sensitive OCTA screening indicators to detect concurrent DR at an early stage.METHODS: A total of 200 patients who treated in the ophthalmology department of the Seventh Affiliated Hospital, Sun Yat-sen University from 2022 to 2023 were included, including 95 first-diagnosed DR patients and 105 patients without DR, and all patients underwent OCTA examination and a collection of demographics and renal function parameters. After a quality check, automated measurements of the foveal avascular zone area, vessel density(VD), and perfusion density(PD)of both 3 mm×3 mm and 6 mm×6 mm windows were obtained.RESULTS: Using random forest and multivariate Logistic regression methods, we developed a diagnostic model for DR based on 12 variables(age, FBG, SBP, DBP, HbA1c, ALT, ALP, urea/Scr, DM duration, HUA, DN, and CMT). Adding specific OCTA parameters enhanced the efficacy of the existing diagnostic model for DR(outer vessel density in 6 mm×6 mm window, AUC=0.837 vs 0.819, P=0.03). In the study of DN patients, the parameters in the 6 mm×6 mm window improved the diagnostic efficacy of DR(inner VD; outer VD; full VD; outer PD; full PD).CONCLUSION:The outer VD in the 6 mm×6 mm window can enhance the efficacy of the traditional DR diagnostic model. Meanwhile, compared with the 3 mm×3 mm window, the microvascular parameters in the 6 mm× 6 mm window focusing on DN patients can be more sensitive to diagnosing the occurrence of DR.

Objective:To describe the distribution characteristics of alcohol consumption in adult twins in the Chinese National Twin Registry (CNTR), and further explore the influence of genetic factors on alcohol consumption in adult twins.Methods:The subjects of the study were twins registered by CNTR in 11 project areas across China from 2010 to 2018. A total of 56 966 twins (28 483 pairs) aged 18 years and above who answered questions about drinking behavior were included, and the random effect model was used to describe the population and regional distribution characteristics of alcohol consumption. Intra-pair analysis was performed to calculate the concordance rate and heritability of their alcohol consumption.Results:The age of all subjects was (36.6±12.0) years, and current drinkers accounted for 16.6% (9 461/56 966) of all subjects. In men, those aged 50-59 years, those in northern China, those living in rural area, those with low education level and those with high BMI, the proportions of current drinkers were higher. After excluding 468 pairs of twins who had stopped alcohol use and 21 764 pairs of twins who had no drink or had small amount drink, an intra-pair analysis was conducted in 4 929 pairs of same-sex twins, and found that the concordance rate of alcohol consumption was 64.0% (2 059/3 215) in monozygotic twins, and 52.6% (902/1 714) in dizygotic twins, the difference was significant ( P<0.001), and the heritability of alcohol consumption was 24.1% (95% CI: 18.9%- 29.3%). The further stratified analysis found that in southern men, the heritability was highest in those aged 40-49 years (36.1%, 95% CI: 21.6%-50.7%), while in northern men, the heritability was highest in those aged 50-59 years (34.2%, 95% CI: 18.1%-50.3%). Conclusions:In adult twins in China, there were population and regional differences in the distribution of alcohol consumption behavior, and alcohol consumption was influenced by genetic factors, and gender, age and region had potential modifying effects.

Objective:To analyze the etiology and clinical characteristics of hospitalized children with fever and cervical lymphadenopathy in general hospital, so as to provide evidence for clinical diagnosis and treatment.Methods:Fifty-six children with fever and cervical lymphadenopathy in the pediatric ward at the Peking University Third Hospital from January 1, 2016 to December 31, 2020 were analyzed retrospectively.They were divided into<6 years old group( n=33) and ≥6 years old group( n=23) according to their ages.The differences of etiological composition among different age groups were analyzed.According to the causes of disease, the cases were divided into infectious disease group and non-infectious disease group.The dynamic changes of etiological composition year by year were analyzed, and the laboratory examination and treatment of children were summarized. Results:Among the 56 cases, 53 cases were confirmed, including 17 cases(30.36%)of acute suppurative lymphadenitis, 13 cases(23.21%)of Kawasaki disease, 13 cases(23.21%)of infectious mononucleosis, seven cases(12.50%)of respiratory tract infection and three cases(5.36%)of histiocytic necrotizing lymphadenitis.As for Kawasaki disease, there were significantly more children in the <6 years old group than that in the ≥ 6 years old group( P=0.005). During the past 5 years, the proportion of infectious diseases have decreased year by year, and the proportion of non-infectious diseases have increased year by year.The difference was statistically significant( χ2=11.443, P=0.022). The levels of leukocyte, neutrophil and quick C-reactive protein in children with non-infectious diseases were higher than those in infectious disease group.The differences were statistically significant(all P<0.05). Among the 56 children, 54 cases(96.4%)were treated with antibiotics.There was no significant difference in the usage rate of antibiotics between the infectious disease group and the non-infectious disease group( χ2=0.019, P=0.890). Conclusion:The main diseases of fever with cervical lymphadenopathy in pediatric inpatients in general hospital are acute suppurative lymphadenitis, Kawasaki disease and infectious mononucleosis, respectively.During the past 5 years, the proportion of non-infectious diseases has increased year by year, but the usage rate of antibiotics has not declined.Clinical attention should be paid to the rational use of antibiotics.

Objective: To investigate the inhibitory effect of polydopamine (PDA) on enamel demineralization in isolated teeth and the induction of hydroxyapatite (HA) production on the surface of demineralized enamel to provide a novel protocol for the prevention and treatment of enamel demineralization. Methods: Twenty isolated bovine teeth were cut into 20 enamel slices and randomly divided into an experimental group and a control group, with 10 slices in each group. The enamel slices in the experimental group were immersed in 2 mg/mL freshly prepared dopamine solution and incubated for 24 hours at room temperature in the dark to prepare the PDA coating, while the control group was left untreated. Then, the isolated bovine teeth, with and without PDA coating, were immersed in artificial demineralization solution at 37 °C for 3 days, followed by 7 days in simulated body fluid (SBF), and the immersion solution was changed daily. The surface morphology of enamel was observed by scanning electron microscopy (SEM), the calcium/phosphorus ratio of the enamel surface was analyzed by energy dispersive spectroscopy (EDS), and the characteristic functional groups in enamel deposits were analyzed by Fourier transform infrared spectroscopy (FTIR). Results: Compared with the control group, the number of demineralized pores produced after 3 d of enamel demineralization with polydopamine coating was less, and the diameter was smaller. EDS elemental analysis showed that the Ca/P ratio after enamel demineralization was 2.37 in the experimental group, which was smaller than the 2.53 ratio in the control group. In the remineralization experiment, after 7 days of remineralization of PDA coated enamel in the experimental group, lamellar grains were produced on the enamel surface, and the growth showed obvious directionality, growth regularity and uniform arrangement. In the control group, the surface of enamel was flocculent mineral deposit, and the crystallinity was poor. The FTIR results proved that the enamel surface deposit of PDA-coated enamel was HA after 7 d of remineralization. Conclusion PDA can affect the nucleation process of HA and promote the production of HA on the surface of demineralized enamel.

Objective:To investigate the relationship between absolute lymphocyte count (ALC) and prognosis of extranodal nasal NK/T cell lymphoma (ENKTL).Methods:The data of 184 patients with ENKTL who were admitted to Shanxi Provincial Cancer Hospital and the Second People's Hospital of Datong in Shanxi Province from January 2002 to December 2018 were retrospectively analyzed. Contal-O'Quigley variable point method was used to calculate the optimal cut-off value of ALC for predicting the prognosis of ENKTL, and the patients were divided into two groups based on this value. Kaplan-Meier method was used to analyze the survival of the two groups of patients. Cox proportional hazard regression model was used for univariate and multivariate survival analyses.Results:According to the Contal-O'Quigley variable point method, the best cut-off value of ALC for predicting ENKTL prognosis was 1.5×10 9/L. According to this value, patients were divided into ALC>1.5×10 9/L group (98 cases) and ALC≤1.5×10 9/L group (86 cases). Compared with the ALC≤1.5×10 9/L group, the proportions of patients with Eastern Cooperative Oncology Group (ECOG) score ≥2 points, serum lactate dehydrogenase (LDH)> 245 U/L, Korean prognostic index (KPI) score 2-4 points and international prognostic index (IPI) score 2-5 points were lower in the ALC>1.5×10 9/L group, but the proportion of patients with hemoglobin > 120 g/L was higher (all P < 0.05). The overall survival (OS) and progression-free survival (PFS) in the ALC>1.5×10 9/L group were better than those in the ALC≤1.5×10 9/L group (3-year OS rate: 65.7% vs. 45.4%, 5-year OS rate: 61.0% vs. 36.6%; 3-year PFS rate: 61.7% vs. 41.0%, 5-year PFS rate: 51.9% vs. 32.2%; all P < 0.05). Multivariate Cox regression analysis showed that ECOG score, serum LDH level, ALC, radiotherapy and L-asparaginase-containing chemotherapy were independent influencing factors of OS and PFS (all P < 0.05), and for OS, when ALC>1.5×10 9/L compared with≤1.5×10 9/L, RR was 0.634 (95% CI 0.398-1.008, P=0.050), and for PFS, RR was 0.625 (95% CI 0.406-0.962, P=0.033). Conclusion:Patients with high ALC have good prognosis, and therefore ALC may be a powerful prognostic factor of ENKTL.
