Objective: To explore the effects of personality and sleep quality with psychological distress of junior and senior high school stduents, so as to provide a reference basis for precise interventions of junior and senior high school students mental health. Methods: In October 2023, a convenience sampling method was used to select 9 034 students aged 12-17 from Shiyan City as the study subjects. The Pittsburgh Sleep Quality Index (PSQI) and Kessler Psychological Distress Scale (K10) were used to collect information on sleep quality and psychological distress of junior and senior high school stduents. Between group comparison was conducted by using t-test and Chi-square test. Generalized linear models were employed to analyze the interaction and joint effects of personality and sleep quality on psychological distress. Results: The generalized linear model analysis showed that the interaction between personality and sleep quality on psychological distress was statistically significant of junior and senior high school students(effect size=0.80, P <0.01). The general linear model analysis indicated that, after adjusting for variables such as age, gender, screen time, and daily sitting time with the extroverted and good sleep quality group as the reference, the introverted and poor sleep quality group had the largest mean difference in psychological distress scores (difference=0.51, P <0.05). When stratified by sleep quality, psychological distress scores were higher in the introverted and neutral personality groups with both poor and good sleep quality compared to the extroverted group (poor sleep quality: introverted difference=3.71, neutral difference=1.14; good sleep quality: introverted difference=2.23, neutral difference=0.57, all P < 0.05). When stratified by personality, psychological distress scores were higher in the poor sleep quality groups for introverted, neutral, and extroverted individuals compared to their good sleep quality counterparts (differences=8.66, 7.83, 7.34, all P < 0.05 ). Conclusions Personality and sleep quality have interactive and joint effects on psychological distress of junior and senior high school stduents. Personalized psychological interventions should be developed based on personality and sleep quality.

OBJECTIVE: To observe the effects of acupuncture on podocyte autophagy and long non-coding RNA SOX2 overlapping transcript (LncRNA SOX2OT)/mammalian target of rapamycin C1 (mTORC1)/Unc-51-like kinase 1 (ULK1) pathway in rats with diabetic kidney disease (DKD), and to explore the mechanism by which acupuncture reduces urinary protein. METHODS: A total of 40 SPF-grade male Sprague-Dawley rats were randomly divided into a control group (n=10) and a modeling group (n=30). The DKD model was established by feeding a high-fat, high-sugar diet combined with intraperitoneal injection of streptozotocin (STZ) in the modeling group. Twenty rats with successful DKD model were randomly divided into a model group (n=10) and an acupuncture group (n=10). The acupuncture group received "spleen and stomach-regulating" acupuncture at bilateral "Zusanli" (ST36), "Fenglong" (ST40), "Yinlingquan" (SP9), and "Zhongwan" (CV12), 30 min per session, once daily, five times per week, for four weeks. The general condition, fasting blood glucose (FBG), 2-hour postprandial glucose (2hPG), serum creatinine (SCr), blood urea nitrogen (BUN), 24-hour urinary protein quantification, and urine albumin-to-creatinine ratio (UACR) were compared before and after the intervention. After intervention, urinary podocyte injury marker SPON2 was measured by ELISA. Podocyte autophagosomes and glomerular basement membrane ultrastructure in renal tissue were observed via transmission electron microscopy. Podocyte apoptosis was assessed by TUNEL staining. The protein expression of microtubule-associated protein 1 light chain 3Ⅱ (LC3-Ⅱ), mTORC1, ULK1, Beclin-1, and p62 in renal tissue was detected by Western blot. LncRNA SOX2OT expression in renal tissue was measured by real-time PCR. RESULTS: After the intervention, compared with the control group, the model group exhibited increased food and water intake, increased urine output, weight loss, and loose stools; compared with the model group, the food and water intake, urine volume, and loose stools were improved in the acupuncture group. Compared with the control group, FBG, 2hPG, SCr, BUN, 24-hour urinary protein quantification, UACR, and urinary SPON2 were all higher in the model group (P<0.01); compared with the model group, the FBG, 2hPG, SCr, BUN, 24-hour urinary protein quantification, UACR, and urinary SPON2 were all lower in the acupuncture group (P<0.01). Compared with the control group, the model group showed reduced podocyte autophagosomes and thickened glomerular basement membrane; compared with the model group, the acupuncture group had increased podocyte autophagosomes and less thickened basement membrane. Compared with the control group, the podocyte apoptosis index (AI) was higher in the model group (P<0.01); compared with the model group, the AI was lower in the acupuncture group (P<0.01). Compared with the control group, the expression of ULK1, Beclin-1, and LC3-Ⅱ proteins was lower, and the expression of mTORC1 and p62 proteins was higher in the model group (P<0.01). Compared with the model group, the expression of ULK1, Beclin-1, and LC3-Ⅱ proteins was higher, and the expression of mTORC1 and p62 proteins was lower in the acupuncture group (P<0.01). Compared with the control group, the LncRNA SOX2OT expression was lower in the model group (P<0.01). Compared with the model group, LncRNA SOX2OT expression was higher in the acupuncture group (P<0.01). CONCLUSION The "spleen and stomach-regulating" acupuncture method could improve renal function in DKD rats, reduce blood glucose and urinary protein excretion, alleviate podocyte injury, and enhance podocyte autophagy. The mechanism may be related to modulation of the renal LncRNA SOX2OT/mTORC1/ULK1 pathway.

Objective:To observe the efficacy of pars plana vitrectomy (PPV) in the treatment of different types of chorioretinal coloboma with retinal detachment (RD).Methods:A single-center, retrospective clinical study. From April 2021 to March 2023, 24 eyes of 23 patients who were diagnosed as chorioretinal coloboma with RD in Henan Provincial Eye Hospital were included in this study. There were 11 males with 12 eyes and 12 females with 12 eyes. The mean age was (33.3±13.7) years old. Best corrected visual acuity (BCVA), spectral domain optical coherence tomography were performed. The BCVA examination was performed using a international standard logarithmic visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. According to the types of chorioretinal coloboma, the affected eyes were divided into the coloboma involved the optic disc group and the coloboma not involved the optic disc group, with 15 eyes and 9 eyes. According to whether the RD containing the coloboma area, the affected eyes were divided into RD containing the coloboma area group and the RD not containing the coloboma area group, with 15 eyes and 9 eyes. All eyes underwent standard pars plana three-channel 25G PPV, retinal laser photocoagulation combined with silicone oil tamponade. The follow-up time after surgery was (19.5±16.3) months. The last follow-up was the time point for efficacy determination. The retinal reattachment, BCVA recovery and postoperative complications were observed. Paired t-test or t test was performed for comparison of quantitative data. Fisher's exact test was performed for comparison of qualitative data. Results:At the last follow-up, retinal reattachment was achieved in 20 eyes (83.3%, 20/24). The logMAR BCVA of the coloboma involved the optic disc group before and after surgery were 1.85±0.62 and 1.71±0.71, the difference was no significant ( t=0.845 , P=0.412). The logMAR BCVA of the coloboma not involved the optic disc group before and after surgery were 1.75±0.45 and 0.84±0.26, the difference was statistically significant ( t=6.153 , P<0.001). The improvement of BCVA in the coloboma not involved the optic disc group was significantly higher than that in the coloboma involved the optic disc group after surgery, with statistically significant differences ( t=3.024 , P=0.006). There was no significant difference in the retinal reattachment rate between the two groups ( P=0.615). There was no significant difference in the retinal reattachment rate between the RD containing the coloboma area group and the RD not containing the coloboma area group ( P=0.259). Postoperative complications included elevated intraocular pressure in five eyes, cataract progression in ten eyes, recurrent RD in two eyes, bullous keratopathy in one eye and band-shaped keratopathy in one eye. Conclusion:PPV combined with silicone oil tamponade is safe and effective in the treatment of chorioretinal coloboma with RD, the improvement of visual acuity in the coloboma not involved the optic disc group is better than that in the coloboma involved the optic disc group after surgery.

BACKGROUND: Evidence on the relations of the American Heart Association's ideal cardiovascular health (ICH) with mortality in Asians is sparse, and the interaction between behavioral and medical metrics remained unclear. We aimed to fill the gaps. METHODS: A total of 198,164 participants without cancer and cardiovascular disease (CVD) were included from the China Kadoorie Biobank study (2004-2018), Dongfeng-Tongji cohort (2008-2018), and Kailuan study (2006-2019). Four behaviors (i.e., smoking, physical activity, diet, body mass index) and three medical factors (i.e., blood pressure, blood glucose, and blood lipid) were classified into poor, intermediate, and ideal levels (0, 1, and 2 points), which constituted 8-point behavioral, 6-point medical, and 14-point ICH scores. Results of Cox regression from three cohorts were pooled using random-effects models of meta-analysis. RESULTS: During about 2 million person-years, 20,176 deaths were recorded. After controlling for demographic characteristics and alcohol drinking, hazard ratios (95% confidence intervals) comparing ICH scores of 10-14 vs. 0-6 were 0.52 (0.41-0.67), 0.44 (0.37-0.53), 0.54 (0.45-0.66), and 0.86 (0.64-1.14) for all-cause, CVD, respiratory, and cancer mortality. A higher behavioral or medical score was independently associated with lower all-cause and CVD mortality among the total population and populations with different levels of behavioral or medical health equally, and no interaction was observed. CONCLUSIONS ICH was associated with lower all-cause, CVD, and respiratory mortality among Chinese adults. Both behavioral and medical health should be improved to prevent premature deaths.

This article elaborates on the role of intestinal flora and its metabolites in the progression of cholesterol gallstones from the aspect of regulation of bile acids by intestinal flora and its metabolites, and it is pointed out that intervention strategies for intestinal flora and its metabolites may be a new target for the prevention and treatment of cholesterol gallstones in the future.

OBJECTIVETo explore the genetic and clinical characteristics of isodicentric Ph chromosomes [idic(Ph)] in lymphoid blast crisis of chronic myeloid leukemia (CML-BLC).

METHODSBone marrow aspirates of 2 patients with CML-BLC were analyzed by R banding after 24 hours of culturing. Genomic copy number variations (CNV) were analyzed by single nucleotide polymorphism array (SNP array) in case 1. The results were confirmed with fluorescence in situ hybridization (FISH). Variations of acute lymphoblastic leukemia-related genes including CDKN2A/AB and PAX5 were detected by multiplex ligation-dependent probe amplication (MLPA).

RESULTSDeletions and duplications on derivative chromosome 9 detected by FISH were confirmed by SNP array analysis. The distances between the BCR/ABL fusion signals on the idic(Ph) chromosomes in the two patients have differed greatly. The idic(Ph) in the second patient was supposed to be formed by two Ph chromosomes joined at their q terminals, where as the idic(Ph) in the first patient have been shown to be fused at the satellite regions of their p arms.

CONCLUSIONThe idic(Ph) chromosomes presented in CML-BLC may predict resistance to Imatinib and response to Dasatinib.

Objective To investigate the related factors of nosocomial infection after severe thoracic trauma so as to provide basis and interventions for lowering nosocomial infection rate.Methods A retrospective case series study was conducted in 148 cases of severe thoracic trauma surgically treated from January 2014 to January 2016.There were 98 males and 50 females with an average age of 34.7 years.The abbreviated injury scale (AIS) was ≥ 3 points.The incidence of nosocomial infection was statistically analyzed.The possible factors related to nosocomial infection were analyzed,including age,gender,previous basic diseases,coma,blood transplantation,surgical procedure,operation time,tracheal intubation time,postoperative tracheotomy,and postoperative ICU hospitalization.Results Nosocomial infection occurred in 18 cases,with infection rate of 12.2％.There were 11 cases of pulmonary infection,four urinary tract infection,two incision infection,and one thoracic cavity infection.There were four cases (22％) of Gram-positive bacteria as pathogen,both of which were Staphylococcus aureus.A total of 12 cases (67％) were Gram-negative bacteria,among which four were infected with Klebsiella pneumonia,three with Acinetobacter baumannii,three with Pseudomonas aeruginosa,and two with Escherichia coli.Two cases were infected by fungi.The incidence of infection was correlated with the patients' age (≥ 60 years),previous basic disease,coma,operation methods,operation time (≥3 hours),endotracheal intubation time (≥24 hours),tracheotomy after surgery,and postoperative hospitalization duration in the ICU (P ＜ 0.05),rather than gender and blood transplantation.Conclusions The most common pathogen of nosocomial infection in severe thoracic trauma patients is Gram-negative bacteria.The older age,previous basic diseases,coma,thoracotomy,long operation time,long tracheal intubation time,tracheotomy and long ICU hospital stay are the risk factors for nosocomial infection.More attention should be paid to these risk factors in order to minimize the occurrence of postoperative hospital infection,and to reduce the harm to patients.

Objective To study the antitumor activity of Xerophilusin G on S180 cells,and Its mechanism.Methods Modified MTT assay was used to test the effect of Xerophilusin G on the proliferation of S180 tumor cell strain.The influences on tumor growth and immune organs of mice with transplanted sarcoma (S180) were observed.The cell cycle of S180 cell lines and mouse sarcoma (S180) was analyzed by flow cytometry.The lymphocyte proliferation activity of spleen stimulating was tested.The level of IL-2 in serum of mice with transplanted sarcoma (S180) was measured by ELISA.Results The IC50 of Xerophilusin G in S180 cell lines was 19.80 μg·mL-1,the LD50 in mouse for Xerophilusin G was 121.11 mg·kg-1 through intraperitoneal injection.The tumor inhibition rate of Xerophilusin G was 32.11％ and 41.60％,respectively at the doses of 3 and 6 mg · kg-1 (P ＜ 0.05).Compared with the control,the thymus,kidney and cardiac index were decreased.The cell proportion at G0/G1 phase of mouse sarcoma (S180) was increased.T and B cell proliferation activities in tumor-bearing mice were enhanced (P ＜ 0.05).As compared with control group,the serum level of IL-2 was decreased 90.9％ and 77.1％ in low-and medium-dose groups,respectively (P ＜ 0.05).Conclusion Xerophilusin G has remarkable effects in sarcoma (S180) bearing mice.The antitumor mechanism of Xerophilusin G might be related with G0/G1 phase arrest of mouse sarcoma (S180) cells and enhancing the activity of T and B cell but not related with increasing the secreting of IL-2.

Objective Subarachnoid hemorrhage ( SAH) is a devastating disease with high fatality and morbidity and micro-glia/macrophage ( M/M) plays a vital role in SAH brain injury with complicated pathophysiological mechanism .This study was to ob-serve the effect of Nrf2 deficiency on M/M activation and M1 polarization after subarachnoid hemorrhage in mice . Meth ods We col-lected 70 wild-type ( WT) ICR mice and 35 Nrf2-knockout ( KO) mice to establish the SAH model by injecting fresh autologous blood into pre-chiasmatic cistern.WT mice were arranged into four groups: sham operation group, post operative day 1 (POD1) group, POD3 group and POD5 group.Then WT mice and Nrf2 Nrf2-knockout mice were divided into sham operation WT group , sham opera-tion KO group, SAH WT group and SAH KO group.Western blotting (WB) and immunohistochemistry (IHC) were applied to observe the activation and proliferation of M/M after SAH on WT mice .Difference in activation and M 1 polarization were observed by detecting Iba1 expression in WB and CD 16/32 +Iba1 +cells in immunofluorescence between WT and KO mice . Results Gray scale values of Iba1 expression by WB in WT mice are 0.491 ±0.039, 0.657 ± 0.069, 0.930 ±0.046 and 0.926 ±0.046;average optical intensity values of Iba1 expression by IHC in WT mice are 0.412 ±0.122, 0.625 ±0.135, 0.963 ±0.213 and 0.978 ±0.224.The data indica-ted that Iba1 expression increased in SAH KO group in comparison to SAH WT group on 1, 3, 5 day after SAH (P<0.05).Moreover, Nrf2 deficiency promoted the activation and polarization of M /M by increased Iba1 protein expression and CD16/32 +Iba1 +cells after SAH ( P<0.05). Conclusion SAH induces M/M activation and proliferation in mice, and Nrf2 deficiency promotes the activa-tion, proliferation and M1 polarization after SAH .
