Objective: To analyze the regulatory effect of Atractylodes macrocephala Koidz. extract on the immune function of mice, so as to provide a reference for the study of the mechanism of Atractylodes macrocephala Koidz. regulating immune function. Methods: Forty-eight SPF healthy male ICR mice were randomly divided into control group and low (0.5 g/kg), medium (2.0 g/kg), and high (4.0 g/kg) dose groups, with 12 mice in each group. The mice in control group were given the pure water by gavage once a day, while the mice in each dose group were given the corresponding dose of Atractylodes macrocephala Koidz. extract by gavage once a day. The delayed allergy test was performed for 28 consecutive days. Sixty SPF healthy male ICR mice were randomly divided into a control group, polyinosinic acid injection group (model group), and low, medium, and high dose groups, with 12 mice in each group. The mice in control group were given the pure water by gavage once a day, while the mice in each dose group were given the corresponding dose of Atractylodes macrocephala Koidz. extract by gavage once a day for 14 consecutive days. On days 13 and 14 of administration, the mice in the model group and each dose group were intraperitoneally injected with sterile polyinosinic acid solution to perform the immunosuppressive experiment induced by polyinosinic acid. The mouse ear pieces were weighed, and the thymus and spleen of the mice were weighed and stained with HE to calculate the pathological scores. Peripheral blood was collected for blood cell detection and T cell classification. Results: Mice in each group had normal feeding, activity, and growth status, and no abnormality was observed. In the delayed allergy test, compared with the control group, the degree and rate of ear swelling in the low, medium and high dose groups were higher, the white blood cell count in the medium dose group was higher, and the absolute values of lymphocytes in the low and medium dose groups were higher (all P<0.05). Compared with the control group, the pathological scores of the thymus and spleen in the model group were higher (both P<0.05). In the immunosuppressive experiments in mice induced by polyinosinic acid, compared with the model group, the pathological score of the thymus in the high dose group was lower (P<0.05), and the boundary between the thymus cortex and medulla was improved. Conclusions Atractylodes macrocephala Koidz. extract can increase the degree of ear swelling and peripheral blood white blood cell count in mice. High dose of Atractylodes macrocephala Koidz. extract can improve the thymus injury induced by polyinosinic acid, and has an immunomodulatory effect.

Objective:To investigate the impact of early blood glucose fluctuations after acute multiple injuries on post-traumatic stress disorder (PTSD).Methods:This study was a case-control study. From March 2022 to March 2023, patients with acute multiple injuries who were admitted to the ICU of the Affiliated Hospital of Xuzhou Medical University were selected. According to whether complicated with traumatic brain injury (TBI), the patients were divided into TBI group and non-TBI group. Early post-traumatic blood glucose fluctuations were observed, including stress-induced hyperglycemia (SIH), initial blood glucose value on admission, blood glucose extreme, short-term glycemic variability (GV) and other related indicators. The 72-hour glucose coefficient of variation (Glu-CV) was used to reflect short-term GV. After 1 month, the PTSD checklist for DSM-5 (PCL-5) was used to assess the patient's symptoms of PTSD. The patients were divided into PTSD group and non-PTSD group according to PCL-5 score ≥38. The differences in short-term glucose fluctuations in each groups were compared; the risk factors of PTSD were analyzed by logistic regression; the receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of related indicators on the incidence of PTSD.Results:159 patients with acute multiple injuries were selected and defined as the TBI group ( n=94) and non-TBI group ( n=65). The incidence of PTSD, PCL-5 scale scores, the incidence of SIH and 72 h Glu-CV in the TBI group were significantly higher than the non-TBI group (all P<0.05). The incidence of SIH and 72 h Glu-CV in the PTSD group were significantly higher than the non-PTSD group (both P<0.05). Multivariate logistic regression analysis showed that 72 h Glu-CV ( OR=1.333, 95% CI: 1.028-1.727, P=0.030) was the independent risk factor for PTSD after acute multiple injuries, and the area under the ROC curve was 0.861 (95% CI: 0.789-0.933, P<0.001), the sensitivity was 62.9% and the specificity was 93.5%. Conclusion:Patients with acute multiple injuries with TBI are more likely to have early glucose fluctuations and develop PTSD, and increased short-term glucose variability is the independent risk factor for PTSD after acute multiple injuries.

Cancer genomics has led to the discovery of numerous oncogenes and tumor suppressor genes that play critical roles in cancer development and progression.Oncogenes promote cell growth and proliferation,whereas tumor suppressor genes inhibit cell growth and division.The dysregulation of these genes can lead to the development of cancer.Recent studies have focused on non-coding RNAs(ncRNAs),including circular RNA(circRNA),long non-coding RNA(lncRNA),and microRNA(miRNA),as therapeutic targets for cancer.In this article,we discuss the oncogenes and tumor suppressor genes of ncRNAs associated with different types of cancer and their potential as therapeutic targets.Here,we highlight the mechanisms of action of these genes and their clinical applications in cancer treatment.Understanding the molecular mechanisms underlying cancer development and identifying specific therapeutic targets are essential steps towards the development of effective cancer treatments.

Objective:To investigate the application value of virtual reality laparoscopic simulator training in laparoscopic transabdominal preperitoneal hernioplasty (TAPP).Methods:The prospective cohort study was conducted. Twenty young physicians from The First Affiliated Hospital of Harbin Medical University with ≥3 years of clinical experience in general surgery and no foundation in laparoscopy were selected for training during July to August 2023. Physicians were divided into two groups based on random number table method. Physicians undergoing virtual reality laparoscopic simulator training were divided into the virtual reality group, and physicians undergoing regular laparoscopic simulator training were divided into the regular group. Two groups of physicians were trained using laparoscopic simulator for 10 days (2 hours for each skill, with a total of 6 hours per day for 3 skills), and the training covered basic laparoscopic surgical skills such as clamping, cutting and suturing and knotting. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups were conducted using the independent sample t test and the paired ttest was used for intra group comparison. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers, and comparison between groups were conducted using the chi-square test. Results:(1) Physicians situation before training. A total of 20 physicians were selected for eligibility. There were 13 males and 7 females, aged 31(range, 30?34)years. There are 7 males and 3 females in the virtual reality group, with age of (31.5±1.4)years and the TAPP simulation surgery time of (42±4)minutes before training. There are 6 male and 4 female students in the regular group, with age of (31.2±1.0)years and the TAPP simulation surgery time of (42±4)minutes before training. There was no significant difference in gender, age, TAPP simulation surgery time between the two groups of physicians ( P>0.05), confounding bias ensured comparability. (2) Basic skills of physicians before and after training. For physicians in the virtual reality group, the clamping score was 5.1±1.0, the cutting score was 4.9±1.0, the suturing and knotting score was 4.7±1.5 before training. The clamping score was 8.0±1.3, the cutting score was 7.9±1.5, the suturing and knotting score was 6.6±1.3 after training. There were significant differences in the above indicators before and after training ( t=?5.75, ?5.21, ?3.07, P<0.05). For physicians in the regular group, the clamping score was 5.3±1.0, the cutting score was 5.0±1.2, the suturing and knotting score was 4.3±1.5 before training. The clamping score was 7.1±1.2, the cutting score was 6.7±1.3, the suturing and knotting score was 5.7±1.1 after training. There were significant differences in the above indicators before and after training ( t=?3.73, ?3.16, ?2.42, P<0.05). (3) Completion of simulated surgical situations before and after training. The time of completing TAPP simulation surgery for virtual reality group after training was (29±3)minutes, versus (42±4)minutes before training, showing a significant difference before and after training ( t=7.69, P<0.05). The time of completing TAPP simulation surgery for regular group after training was (36±4)minutes, versus (42±4)minutes before training, showing a significant difference before and after training ( t=3.75, P<0.05). The time of completing TAPP simulation surgery of virtual reality group after training was shorter than that of regular group, showing a significant difference between the two groups ( t=?3.89, P<0.05). Conclusion:Both of virtual reality and regular laparoscopic simulator can enhance the basic laparoscopic surgical skills and the proficiency of TAPP simulation surgery of physicians, and the training effect of virtual reality laparoscopic simulators is better.

Objective To investigate the relationship between serum interleukin-1β(IL-1β),C-reactive pro-tein to albumin ratio(CAR)and heparin-binding protein(HBP)levels and secondary pulmonary Candida albi-cans infection during chemotherapy in patients with lung cancer.Methods A total of 175 patients with lung cancer admitted to this hospital from January 2018 to April 2022 were selected,and all patients were treated with chemotherapy.According to whether they had secondary pulmonary Candida albicans infection,they were divided into infection group(37 cases)and non-infection group(138 cases).The clinical data,serum levels of IL-1β,HBP and CAR were compared between the two groups.Multivariate Logistic regression analysis was used to analyze the influencing factors of secondary pulmonary Candida albicans infection in patients with lung cancer during chemotherapy.The receiver operating characteristic(ROC)curve was used to analyze the pre-dictive value of serum IL-1β,CAR and HBP for secondary pulmonary Candida albicans infection during chemo-therapy,and the prognosis of lung cancer patients with different serum IL-1β,HBP levels and CAR were com-pared.Results There were significant differences in smoking,pathological stage,diabetes mellitus,chemo-therapy cycle,chronic obstructive pulmonary disease and anatomical location between the infection group and the non-infection group(P＜0.05).The serum levels of IL-1β,HBP and CAR in the infection group were higher than those in the non-infection group(P＜0.05).Multivariate Logistic regression analysis showed that smoking,diabetes,anatomical site,chronic obstructive pulmonary disease,pathological stage,chemotherapy cycle and serum IL-1β,HBP,CAR were the influencing factors of secondary pulmonary Candida albicans infec-tion in patients with lung cancer during chemotherapy(P＜0.05).The area under the curve(AUC)of serumIL-1β,CAR and HBP in predicting pulmonary Candida albicans infection was 0.779,0.732 and 0.796,respec-tively.The AUC of the combination of the three was 0.931,and the sensitivity and specificity were 86.49％and 90.58％,respectively.The survival rate of lung cancer patients with high levels of IL-1β,CAR and HBP was sig-nificantly lower than that of patients with low levels of Il-1β,CAR and HBP(P＜0.05).Conclusion The in-crease of serum IL-1β,CAR and HBP levels in patients with lung cancer is related to secondary pulmonary Candida albicans infection during chemotherapy.Detection of these serum Il-1β,CAR and HBP levels is helpful to predict the risk of pulmonary Candida albicans infection and death.

ObjectiveTo analyze the suicidal behavior in hospitalized patients with major depression and its influencing factors. MethodsA total of 1 000 patients with major depression admitted to our hospital from January 2017 to July 2021 were selected as the research subjects to investigate the status quo of suicidal behavior of the enrolled patients. According to the survey results， the patients were divided into suicidal behavior group and non-suicidal behavior group， and the related factors affecting their suicidal behavior. ResultsA total of 511 cases （51.10%） of the patients with major depression committed suicide in hospital， including 271 cases （27.10%） of suicidal ideation， 186 cases （18.60%） of attempted suicide， and 54 cases （5.40%） of suicide death. 489 patients （48.90%） did not commit suicide. Univariate analysis showed that there were significant differences in age， gender， marital status， loss of interest or pleasure， anxiety， sense of worthlessness or self-guilt， sleep status， personality， depressive episodes and paranoia between the suicidal behavior group and the non-suicidal behavior group （all P<0.05）. Logistic multifactorial regression analysis showed that age ≤28 years （OR=1.54）， female （OR=1.93）， anxiety （OR=1.61）， sense of worthlessness or self-guilt （OR=1.85） and paranoia （OR=2.15） were all independent predictors of suicidal behavior in the patients with major depression. ConclusionThe incidence of nosocomial suicide in patients with major depression is high. Early onset age， female， anxiety， sense of worthlessness or self-guilt， more depressive episodes and paranoia are independent risk predictors of suicide in patients with major depression. This finding can be used for clinical intervention to reduce the occurrence of suicide in patients.

Objective:To investigate the predictive value of controlling nutritional status (CONUT) score in the prognosis of patients with advanced diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was performed. The clinical data of 654 patients newly diagnosed with advanced DLBCL diagnosed in 7 medical centers in Huaihai Lymphoma Working Group from October 2009 to January 2022 were retrospectively collected. All the patients received rituximab-based immune chemotherapy regimens. The patients were randomly assigned to the training set (458 cases) and the validation set (196 cases) in a 7:3 ratio. The clinicopathological data of patients were collected, and the CONUT score was calculated based on albumin, lymphocyte count, and total cholesterol. The optimal critical value of CONUT scote was determined by using MaxStat method. Kaplan-Meier method was used to draw survival curves; Cox proportional hazards model was used to make univariate analysis and multivariate analysis on the factors influencing overall survival (OS). The efficacy of CONUT score in combination with the International prognostic index (IPI) and an enhanced IPI (NCCN-IPI) in predicting OS was evaluated by using receiver operating characteristic (ROC) curves.Results:The median follow-up time of 654 patients was 38.1 months (95% CI: 35.3 months- 40.9 months), and the 5-year OS rate was 49.2%. According to the MaxStat method, the optimal critical value for CONUT score was determined to be 6 points. All the patients were classified into the normal nutritional status group (CONUT score ≤ 6 points, 489 cases) and the poor nutritional status group (CONUT score > 6 points, 165 cases). The results of the multivariate analysis showed that CONUT score > 6 points, male, lactate dehydrogenase >240 U/L, high white blood cell count, low hemoglobin level and age > 60 years were independent risk factors for OS of patients with advanced DLBCL (all P < 0.05). Patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group in the overall cohort of advanced DLBCL. Subgroup analysis revealed that among patients with Eastern Cooperative Oncology Group-performance status (ECOG PS) score < 2 points, IPI low-intermediate risk, IPI intermediate-high risk, NCCN-IPI low-intermediate risk, and NCCN-IPI intermediate-high risk, the patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group (CONUT score ≤ 6 points) (all P < 0.05). Conclusions:CONUT score has a certain value in the assessment of the prognosis of patients with advanced DLBCL, and its predictive efficacy is further improved when combined with IPI and NCCN-IPI.

Objective To explore the developmental changes in the expression of Rap1B and the effect of monocular form deprivation(MD)during the critical period of visual development on the expression of Rap1B in the mouse superior colliculus(SC).Methods Forty-five SPF-grade healthy male C57BL/6J mice were used in this experimental study.Ex-periment 1:To study the developmental changes of Rap1B expression in the mouse SC,the experimental mice were divided into three groups:the pre-critical period group[postnatal day 18(P18)],the critical period group(P32),and the adult group(P60).The expression levels of Rap1B gene and protein in the left and right SC of mice in each group were detected by quantitative polymerase chain reaction(qPCR)and Western blot,respectively.Experiment 2:To study the effect of MD on the expression levels of Rap1B gene and protein in the SC,the experimental mice were divided into two groups:the right eye MD group(MD models of the right eyes were established at P28 and detected at P32)and the normal control group(NC group,P32).The expression levels of Rap1B gene and protein in the left and right SC of mice in each group were measured by qPCR and Western blot,respectively.Results The expression levels of Rap1B gene and protein were low in the left and right SC of mice in the pre-critical period group;compared with the pre-critical period group,the ex-pression levels of Rap1B gene and protein in the critical period group significantly increased(both P＜0.05);compared with the critical period group,the expression levels of Rap1B gene and protein in the adult group significantly decreased(both P＜0.05).Mice in the right eye MD group showed significantly higher expression levels of Rap1B gene and protein in the left SC(both P＜0.05),while significantly lower expression levels of Rap1B gene and protein in the right SC(both P＜0.05)compared to mice in the NC group.Conclusion The developmental trend of Rap1B gene expression in the mouse SC is consistent with the critical period of visual development,and Rap1B may be involved in the regulatory effect of MD during the critical period on the development of SC.

Objective:To improve the accuracy of ultrasound for the diagnosis of Abernethy malformation in children, and to achieve a comprehensive ultrasound evaluation of its complications and associated malformations.Methods:The data of 7 children who underwent ultrasound examination and confirmed with Abernethy malformation by computed tomography angiography(CTA) and/or percutaneous angiography in the Children′s Hospital of Zhejiang University School of Medicine from March 2020 to December 2023 were retrospectively collected. All the children received routine cardiac ultrasound examination, and those with hypoxemia also received right heart contrast echocardiography. The clinical manifestations were analyzed, and the ultrasound characteristics of Abernethy malformation, its complications, associated malformations and examination method were summarized.Results:Abernethy malformation was detected by accident as physical examination, fever, and trauma in 3 of the 7 children. The other 4 cases presented with clinical symptoms. Abernethy malformation in all 7 children was first detected and diagnosed by ultrasound. In 3 cases, the surgical results confirmed that the type of Abernethy malformation determined by ultrasound was correct. The complications of Abernethy malformation included focal nodular hyperplasia in 2 cases, gastrointestinal bleeding and nephrotic syndrome in 1 case, and pulmonary hypertension in 1 case. The right heart contrast echocardiography results of 2 cases with hypoxia symptoms suggested that their right-to-left shunts were graded Ⅱ and Ⅲ, respectively.Therefore, 2 cases were complicated by hepatopulmonary syndrome. Among these 7 cases, 4 cases had congenital heart disease, one of whom had polysplenia syndrome. Shunt vascular occlusion under digital subtraction angiography monitoring was performed in 1 case.Two cases underwent liver transplantation. Three cases were being followed up. One case abandoned treatment.Conclusions:Ultrasound has high accuracy in the diagnosis of Abernethy malformation in children and can locate portosystemic shunt vessels. In addition to abdominal organ and vascular ultrasound examination, routine echocardiography is recommended for children with Abernethy malformation. Right heart contrast echocardiography provides important information for the diagnosis of hepatopulmonary syndrome in children with hypoxia symptoms.
