Sleep deprivation refers to the loss of sleep caused by self-inflicted or external factors. There is increasing evidence that pregnancy is prone to sleep deprivation, which not only disrupts maternal functions but also affects offspring′s cognitive function. This article reviews the effects of sleep deprivation during pregnancy on offspring cognition and its underlying mechanisms, in order to establish a foundation for developing scientifically sound sleep strategies during pregnancy and to provide clinical insights for improving the neurodevelopment and cognitive function of offspring.

Objective To evaluate the efficacy of Schroth PSSE combined with 3D printing braces in the treatment of adolescent idiopathic scoliosis.Method Forty patients were included and divided into a support group(3D printing support group)and a support+exercise therapy group(3D printing support+Schroth PSSE group).Excluding outliers and lost follow-up data,32 patients were ultimately included,with 16 patients in each group.Wearing time≥18 h for both groups of 3D printing supports.The intervention period of Schroth PSSE is 12 weeks,and exercise is maintained after 12 weeks until the end of follow-up.The longest follow-up time for the brace group was 25 months,with an average follow-up time of(15.00±1.29)months.The longest follow-up time for the brace+exercise therapy group was 24 months,with an average follow-up time of(16.59±1.01)months.Relevant indicators were evaluated after follow-up.Results The support and exercise therapy group showed better improvement in Cobb angle and trunk rotation angle(ATR)than the support group,with statistically significant differences(P<0.05);The distance between the midpoint of the C7 vertebral body and the midline of the sacrum(C7-CSVL)in the support and exercise therapy group showed a statistically significant difference before and after treatment(P<0.05),while there was a significant difference before and after Apical Vertebral Translation(AVT)treatment(P<0.01).There was no statistically significant difference compared to the support group(P<0.05);In terms of SRS-22 score,the brace+exercise therapy group can comprehensively improve the SRS-22 score.Conclusion The combination of Schroth PSSE and 3D printing braces has a better effect on improving Cobb angle and torso rotation angle,improving coronary imbalance,increasing patient satisfaction,and improving quality of life compared to using 3D printing braces alone.

Objective To investigate the clinical value of extracellular volume(ECV)based on CT delayed phase in combination with pathologic indicators in predicting early recurrence of gastric mesenchymal tumors after surgery.Methods A retrospective case-control trial was conducted on the imaging,clinical and pathological data of 110 patients with gastric mesenchymal tumors who were surgically resected at the First Affiliated Hospital of Army Medical University from January 2011 to August 2022.They were 60 males and 50 females,at a mean age of 58±10 years.All of them received preoperative multiphase dynamic CT enhancement examination of the abdomen,and ECV value was calculated with the formula:ECV=(1-hematocrit)×(△HU tumor/△HU aorta).According to the postoperative recurrence within 24 months after surgery,they were divided into early recurrence group and non early recurrence group.Statistical indexes:① Consistency analysis.② The factors affecting early recurrence after resection of gastric mesenchymal stromal tumors were analyzed and a prediction model was conducted.Delong test was used to assess the predictive value of the model.Then a nomogram was plotted based on the combines model,and calibration curves were drawn to assess the efficacy of the column charts,and decision curve analysis(DCA)was adopted to assess the value of the model for clinical application.Results ① Consistency analysis.After 2 radiologists outlined the region of interest and obtained ECV value according to the above formula,The intraclass correlation coefficient(ICC)was 0.806.② For the 110 subjected patients,21 cases of them had early recurrence,and 89 one did not.Multivariate analysis showed that ECV value,risk degree,and tumor length were independent influencing factors for predicting early recurrence.Receiver operating characteristic(ROC)curve analysis indicated that the area under the curve(AUC)value of ECV,hazard degree,and tumor length diameter in predicting early recurrence was 0.838(95％CI 0.758～0.918),0.774(95％CI 0.656～0.892),and 0.700(95％CI 0.589～0.810),respectively,and the value of their combined model was 0.899(95％CI 0.811～0.987),which was higher than that of each independent model.The sensitivity and specificity of the combined model was 85.71％and 86.52％,respectively,and the optimal cutoff value was 0.19.Delong test revealed that there was statistical difference between the combined model and the clinical model established by the hazard level(Z=6.548,P＜0.001,95％CI 0.140～0.259).Calibration curve analysis suggested that the combined model had a better fit,and DCA displayed that the combined model had a better net benefit.Conclusion The model established by ECV combined with pathological indicators has good predictive performance and can be used as a more effective predictor of early recurrence of gastric mesenchymal tumors after surgery.

AIM:To investigate the effect of a disintegrin and metalloproteinase(ADAM)domain-like decy-sin 1(ADAMDEC1)knockdown on the proliferation,migration and invasion of pancreatic carcinoma cells.METHODS:Expression levels of ADAMDEC1 in pancreatic carcinoma tissues were analyzed using the GEPIA and UALCAN online da-tabases.Western blot analysis was employed to detect the protein expression levels of ADAMDEC1 in pancreatic carcino-ma cell lines(MIA PaCa-2 and PANC-1)and pancreatic ductal cell line(hTERT-HPNE).The effects of ADAMDEC1 knockdown on cell proliferation,migration and invasion were evaluated using CCK-8,colony formation,wound-healing and Transwell assays.Additionally,Western blot analysis was used to detect the effects of ADAMDEC1 knockdown on the expression levels of migration and invasion markers,as well as Wnt/β-catenin signaling pathway-related proteins in pancre-atic carcinoma cells.Furthermore,a recovery experiment was conducted to assess the role of Wnt/β-catenin signaling path-way agonist CHIR-99021 in ADAMDEC1 knockdown-induced inhibition of pancreatic carcinoma cell growth and migra-tion.RESULTS:(1)ADAMDEC1 was highly expressed in pancreatic carcinoma cells.(2)Knockdown of ADAMDEC1 led to a significant reduction in the proliferation,migration and invasion of pancreatic carcinoma cells.(3)Knockdown of ADAMDEC1 resulted in increased E-cadherin protein expression and decreased levels of matrix metalloproteinase 9,N-cadherin and vimentin proteins,alongside a reduction in the expression of Wnt/β-catenin signaling pathway-related pro-teins.(4)Co-treatment of pancreatic carcinoma cells with CHIR-99021 and ADAMDEC1 small interfering RNA reversed the inhibitory effects of ADAMDEC1 knockdown on cell proliferation,migration,and invasion.CONCLUSION:ADAMDEC1 is highly expressed in pancreatic carcinoma.Targeted silencing of ADAMDEC1 has the potential to inhibit the prolifera-tion,migration and invasion of pancreatic carcinoma cells by regulating the Wnt/β-catenin signaling pathway.

AIM:To investigate the impact and regulatory mechanisms of zinc finger protein 36-like protein 1(ZFP36L1)on pancreatic carcinoma cell growth.METHODS:The ZFP36L1 expression in pancreatic carcinoma and its correlation with patient prognosis were analyzed using online databases UALCAN and GEPIA.Western blot was utilized to detect ZFP36L1 protein expression in pancreatic ductal cells(HPNE)and three different pancreatic carcinoma cell lines.CCK-8 and cell colony formation assays were performed to evaluate the effects of ZFP36L1 on pancreatic cancer cell prolif-eration.Wound healing and Transwell assays were used to assess the impact of ZFP36L1 expression changes on pancreatic carcinoma cell migration and invasion.Flow cytometry experiments were used to analyze the effect of ZFP36L1 on the pan-creatic carcinoma cell cycle process.Bioinformatics analysis was conducted to predict potential ZFP36L1 interacting pro-teins.Co-immunoprecipitation experiments were carried out to confirm the interaction between ZFP36L1 and mitogen-acti-vated protein kinase 14(MAPK14).Rescue experiments were performed to assess the function of MAPK14 in ZFP36L1-regulated pancreatic carcinoma cell growth.RESULTS:(1)ZFP36L1 is highly expressed in pancreatic carcinoma and is positively correlated with poor prognosis in pancreatic carcinoma patients.Compared to HPNE,ZFP36L1 is highly ex-pressed in MIA PaCa-2 and ASPC-1 cells,but relatively low in PANC-1 cells.(2)ZFP36L1 overexpression significantly increased the cell viability,colony formation,migration,and invasion abilities of PANC-1 and MIA PaCa-2 cells,while siRNA interference of ZFP36L1 led to opposite results.(3)ZFP36L1 promotes the entry of pancreatic carcinoma cells into the S phase of the cell cycle.(4)ZFP36L1 interacts with MAPK14 to regulate pancreatic cancer cell growth.MAPK14 overexpression reversed the cell viability and migration abilities of pancreatic carcinoma cells overexpressing ZFP36L1.Furthermore,it also decreased the cell viability and migration abilities of pancreatic carcinoma cells with ZFP36L1 inter-ference.CONCLUSION:ZFP36L1 is a potential oncogene in pancreatic carcinoma growth and may regulate pancreatic carcinoma cell growth through cell cycle modulation and interaction with MAPK14.

  Objective  To summarize the clinical manifestations, pathological features and gene mutation diversity of Blau syndrome/early-onset sarcoidosis.  Methods  We collected general data, clinical manifestations, and auxiliary examination results from 8 patients who were diagnosed of Blau syndrome/early-onset sarcoidosis and treated in our hospital from January 2011 to December 2022, and then summarized and analyzed their characteristics and diversity.  Results  Among the 8 patients, 4 were males and 4 were females. The onset age was 3 to 8 months old. Rash was the first symptom in 7 patients(87.5%). 6 patients(75.0%) had papules and erythema.3 cases(37.5%) had arthritis. 2 cases(25.0%) had uveitis and other eye inflammation. 4 cases (50.0%) also showed intermittent fever. 3 cases (37.5%) showed symptoms in nerve and respiratory system, and hypertension respectively. The skin histopathology of 8 patients showed non-caseous granuloma formation. In laboratory detection, CRP and TNF-α were significantly increased before treatment, while IL-6, IL-8, TNF-α and IL-2 receptor(IL-2R) were significantly decreased in 5 patients after glucocorticoid therapy. The results of genetic testing showed that 4 of the 7 patients had p.R334W(c.1000C > T) mutation, 1 had p.H313R(c.938A > G) and p.R471C(c.1411C > T)double mutation, and 1 had p.476_477del (c.1427_1429delcct).  Conclusions  Blau syndrome/early-onset sarcoidosis has significant features in clinical manifestations, histopathology and gene mutation, but it also has diversity.

Objective To investigate the relationship between serum indexes and the degree of liver fibrosis in chronic hepatitis B(CHB)patients with HBeAg-negative and normal ALT,and to establish a new non-invasive model for predicting liver fibrosis in CHB patients.Methods The clinical data of 679 HBeAg-negative chronic HBV infected patients with normal ALT who underwent liver biopsy from October 2012 to December 2021 were retrospectively analyzed.Among these patients,they were categorized into the control group(S1,observation group)the and significant fibrosis group(S2/S3/S4,control group)based on liver biopsy results.The LASSO regression model was used for covariates selection and the restricted cubic splines model was used to examine nonlinear associations between covariates and outcomes.We used Logistic regression models to establish predictive models.Results Liver biopsy showed that 48.7%of the patients had obvious fibrosis(S≥2).GGT shows a nonlinear relationship with the degree of liver fibrosis.AST and PT show a positive relationship with the liver fibrosis degree,respectively.The area under the ROC curve(AUC)of GGT + PT + AST is 0.68(95%CI:0.64～0.72),and this model performed better than models established using GPR,APRI,and FIB-4.Conclusion The prediction model of GGT + PT+AST has high predictive value on the severity of liver fibrosis among CHB patients whose HBeAg is negative.

Objective: To establish a risk assessment system for the prevention and control of infectious diseases in primary and secondary schools in Tianjin and reduce the risk of infectious disease prevention and control through risk assessment and control. Methods: Based on the failure modes and effect analysis method, a quantitative risk assessment of infectious disease prevention and control in 45 primary and secondary schools in Tianjin was carried out. Risk based supervisory process was assessed, while control effect was evaluated for contined improvement in the prevention and control of infectious diseases in the primary and secondary schools. Results: The top three risk aspects found in the infectious disease prevention and control system in primary and secondary schools in Tianjin included failure to provide sanitation professionals (82.22%) in accordance with regulations, no hand sanitizer or disinfectant (35.56%) in wash basins, and drinking water related products without approval (28.89%). The results of the risk assessment indicated that the three risk aspects with the highest risk priority number (RPN) included failure to provide health professionals( n = 144), no morning and afternoon inspection arrangement( n =126), and low quality of morning and afternoon inspections( n =126). After optimizing the supervision measures for the risk aspects with a detectable degree≥7 points, a quantitative risk assessment was carried out again, the RPN values of all risk points fell below 125, indicating reasonable control effect. Conclusion Based on the failure mode and effect analysis method, the establishment of a risk assessment system for the prevention and control of infectious diseases in primary and secondary schools and regular risk assessments can timely detect risk aspects in the infectious disease prevention and control, to promote effective prevention of infectious diseases in schools.

Older adults have decreased control of body balance with aging and are prone to fall. As the primary point of contact between human body and ground, footwear is critical for stability of older adults. The relationship between shoe characteristics and stability of older adults was systematically reviewed to determine the effect of footwear characteristics on stability of older adults. The results show that wearing shoes with shoelaces or velcro, low heels, wide outsole and appropriate soles, or using vibrating insoles and arch support insoles can help older adults improve their stability. Excessive sole spring and low sole hardness may have adverse effects on stability of older adults. This study can provide theoretical references for older adults to choose shoes reasonably and for the manufacturers to design and make shoes to prevent falls.

Objective To evaluate the effect of berberine on fatty liver ischemia-repeffusion (I/R) injury and the relationship with endoplasmic reticulum stress in liver tissues.Methods Thirty-two male Wistar rats,aged 4 weeks,weighing 100-150 g,were divided into 4 groups (n=8 each) using a random number table method:control group (group C),fatty liver group (group FL),I/R group and berberine group (group BBR).Rats were fed a normal fat diet for 12 weeks,normal saline 3.5 ml was given intragastrically for 4 weeks starting from 9th week,and rats only underwent simple laparotomy in group C.Rats were fed a high-fat diet (45％ energy originating from fat) for 12 weeks,and the other treatments were similar to those previously described in group C.Rats were fed a high-fat diet (45％ energy originating from fat) for 12 weeks,normal saline 3.5 ml was given intragastrically for 4 weeks starting from 9th week,and then the model of liver I/R injury was established in group I/R.Rats were fed a high-fat diet (45％ energy originating from fat) for 12 weeks,berberine solution (300 mg/kg) 3.5 ml was given intragastrically for 4 weeks starting from 9th week,and then the model of liver I/R injury was established in group BBR.Hepatic ischemia was induced by clamping the portal vein,hepatic artery,right gastric vein,and supra-and inferior-hepatic vena cava to perform cold perfusion with 4 ℃ lactated Ringer's solution lasting for 30 min,followed by reperfusion.The serum triglyceride (TG) concentrations were determined after 4,8 and 12 weeks of diet.Blood samples were collected at 6 h of reperfusion for measurement of serum aspartate transminase (AST) and alanine transaminase (ALT) concentrations.Livers were removed after blood sampling at 6 h of reperfusion and liver tissues were obtained and stained with oil red O and haematoxylin and eosin for examination of pathological changes and for determination of the expression of Bip,CCAAT/enhancer-binding protein homologous protein (CHOP),protein kinase RNA-like endoplasmic reticulum kinase (PERK) and phosphorylated PERK (p-PERK) (by Western blot).p-PERK/PERK ratio was calculated.Results Compared with group C,the serum TG,ALT and AST concentrations were significantly increased,the expression of Bip and CHOP was up-regulated,p-PERK/PERK ratio was increased (P＜0.05),lipid deposition was increased,and liver steatosis was found in group FL.Compared with group FL,the serum AST and ALT concentrations were significantly increased,the expression of Bip and CHOP was up-regulated,pPERK/PERK ratio was increased (P＜0.05),and the pathological changes of liver tissues were accentuated in group I/R.Compared with group I/R,the serum TG,ALT and AST concentrations were significantly decreased,the expression of Bip and CHOP was down-regulated,p-PERK/PERK ratio was decreased (P＜ 0.05),lipid deposition was reduced,and the pathological changes of liver tissues were significantly attenuated in group BBR.Conclusion Berberine can ameliorate fatty liver I/R injury,and the mechanism may be related to inhibiting endoplasmic reticulum stress in liver tissues of rats.
