Objective To explore the risk factors of apathy and correlations with cognitive function in patients with hypertension combined with cerebral small vessel disease(CSVD).Methods Totally 141 patients with hypertension combined with CSVD were prospectively enrolled and were divided into apathy group(n=43)and non-apathy group(n= 98)according to neuropsychiatric inventory-apathy scale(NPI-Apathy)scores.The general data,imaging marker scores and total imaging burden scores were compared between groups.In hypertension combined with CSVD patients,multivariate logistic regression analysis was performed to screen the independent risk factors of apathy,and Spearman correlation analysis was also performed to observe the correlation of apathy and cognitive function.Results The patients'age,high density lipoprotein cholesterol(HDL-C),Fazekas scores of lateral periventricular white matter hyper-intensity(WMH),cerebral microbleed of depth/infratentorial and total imaging burden scores of apathy group were all higher,while mini-mental state examination(MMSE)and Montreal cognitive assessment(MoCA)scores were both lower than those of non-apathy group(all P＜0.05).HDL-C and Fazekas scores of lateral periventricular WMH were both independent risk factors for apathy(both P＜0.05),while NPI-Apathy scores were moderately negatively correlated with cognitive function in patients with hypertension combined with CSVD(r=-0.543,-0.484,both P＜0.001).Conclusion HDL-C and Fazekas scores of lateral periventricular WMH were both independent risk factors for apathy in patients with hypertension combined with CSVD.The more severe the apathy,the lower the cognitive function.

Objective: To explore perceived social support levels of vocational school students and associated factors, so as to provide a basis for the fine tuned construction of social support networks for vocational school students. Methods: Adopting a combination of multi stage cluster sampling and convenience sampling method, a sample of 11 767 vocational school students in Shanghai City and Jiangsu Province were selected to conduct two surveys (November 2021 and November 2022) by using a self administered electronic questionnaire regarding personal, family, school information and the Child and Adolescent Social Support Scale (CASSS). Correlates were analyzed by generalized linear estimating equations (GEE). Results: The total perceived social support scores in percentage at baseline and follow up survey were (66.13±20.46) and (67.65±21.18). The results of GEE showed that in terms of personal characteristics, girls had higher emotional support and evaluative support scores than boys ( B=0.60, 0.68, P < 0.05 ); extraversion, non-smoking, non-drinking, exercising ≥1 time per week, and better quality of sleep were positively correlated with the total score and the different types scores of precieved social support, and time spent on the Internet >2 h/d was negatively correlated with the total score and the different types scores of precieved social support ( B=1.03-4.49, -4.04--0.58, P < 0.05 ). In terms of family characteristics, parents not in marriage and living with (external) grandparents were negatively correlated with the total score and different types scores of percieved social support, while family characteristics such as satisfaction with family income (average, satisfactory, very satisfactory) and parents education level of junior high school and above were positively correlated with the total score and the different types scores of precieved social support ( B=-1.34--0.37, 0.57-2.37, P <0.05). In terms of school characteristics, without experience of bullying in school and the number of same sex or opposite sex friends >1 were positively correlated with the total score and different types scores of perceptual social support, and without serving as an officer of a student organization was negatively correlated with the total score and the different types scores of precieved social support ( B= 1.21- 5.04, -2.00--0.76, P <0.05). Conclusions The levels of overall and different types of precieved social support among vocational school students need to be improved. According to individual, family, and school related factors of precieved social support can help to target the improvement of students precieved social support level.

OBJECTIVE To investigate the impact of the methionine synthase reductase （MTRR） rs10380 C＞T gene polymorphism on methotrexate （MTX） plasma concentration， adverse drug reaction， and prognosis in children with intracranial tumors. METHODS Peripheral blood was collected from children with intracranial tumors， and genomic DNA was extracted. The MTRR rs10380 C＞T genotype was analyzed using matrix-assisted laser desorption/ionization-time of flight-mass spectrometry. The association of the MTRR rs10380 C＞T gene polymorphism with the ratio of MTX plasma concentration to dose （C/D ratio）， adverse drug reaction， tumor recurrence， and metastasis was analyzed. Bioinformatics analysis was used to explore the association of the rs10380 genotype and MTRR gene expression and its possible mechanisms. RESULTS A total of 75 children were included in the study. The distribution frequencies of the wild-type CC genotype and C allele of rs10380 were 62.67% and 81.33%， respectively， while the distribution frequencies of the variant CT genotype and T allele were 37.33% and 18.67%， respectively， which were in accordance with Hardy-Weinberg equilibrium（P＞0.05）. The incidence of electrolyte disorders （51.06%） and tumor metastasis rate （57.45%） in children with the CC genotype were significantly higher than those with the CT genotype （P＜0.05）. No significant differences were observed in the 24-hour and 42-hour C/D ratios and recurrence rates between the two genotypes of children （P＞0.05）. Bioinformatics analysis showed that MTRR protein mainly works in conjunction with 10 proteins， including MMAA， and was involved in various biological processes such as sulfur amino acid biosynthesis. CONCLUSIONS The MTRR rs10380 CC genotype may be a risk factor for electrolyte disorders and tumor metastasis in children with intracranial tumors after MTX chemotherapy.

Objective To explore the effects and mechanism of Baitouweng Decoction in intestinal mucosal healing in mice with ulcerative colitis(UC)based on RIPK1/RIPK3/MLKL signaling pathway.Methods Totally 30 C57BL/6 male mice were randomly divided into control group,model group,Baitouweng Decoction group,infliximab group and combination group(Baitouweng Decoction+infliximab),with 6 mice in each group.A mouse model of UC was established by free administration of 3.5%sodium gluconate sulfate solution for 7 days.After modeling,Baitouweng Decoction group was given 8 g/kg Baitouweng Decoction solution by gavage daily,while the infliximab group was given 5 mg/kg infliximab intraperitoneal injection,the combination group was given synchronous gastric and intraperitoneal injection,while the control group and model group were given equal volume of normal saline by gavage for 7 consecutive days.The body mass of mice was recorded daily,fecal characteristics were observed,and disease activity index(DAI)score was performed,colon length was measured after intervention,ELISA was used to detect the contents of serum interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α),RT-qPCR was used to detect mRNA expressions of RIPK1,RIPK3 and MLKL in colon tissue,Western blot and immunofluorescence staining were used to detect the expressions of RIPK1,RIPK3 and MLKL protein in colon tissue.Results Compared with the control group,the model group mice showed a decrease in body mass(P<0.01),an increase in DAI score(P<0.01),a shortened colon length(P<0.01),and an increase in serum IL-6 and TNF-α content(P<0.01);colonic mucosal was destructed,with disappearance of crypts and glandular structures,extensive infiltration of inflammatory cells,and increased pathological score of colon tissue(P<0.01);the mRNA and protein expressions of RIPK1,RIPK3 and MLKL in colon tissue increased(P<0.01,P<0.05).Compared with the model group,the body mass of mice in each treatment group increased(P<0.01),and the DAI score decreased(P<0.01),colon length increased(P<0.01),and the contents of serum IL-6 and TNF-α decreased(P<0.05,P<0.01);the destruction of the colonic mucosal barrier was reduced,the pathological score of colon tissue was reduced(P<0.05);the expressions of RIPK1,RIPK3 and MLKL mRNA and protein in colon tissue decreased(P<0.05,P<0.01).Conclusion Baitouweng Decoction can alleviate intestinal mucosal damage and inflammation in UC mice,and its mechanism may be related to the inhibition of the RIPK1/RIPK3/MLKL signaling pathway.

Objective To investigate the predictive value of color Doppler ultrasound parameters for fetal growth restriction (FGR) induced by hypertensive disorders of pregnancy in high-altitude regions. Methods Pregnant women with gestational hypertension who were treated between July 2020 and June 2022 at the Affiliated Hospital of Qinghai University (with altitude of 2, 300 meters, were divided into group A1 with 19 cases and group A2 with 51 cases according to occurrence of FGR), Yushu People's Hospital (with altitude of 3, 700 meters, were divided into group B1 with 25 cases and group B2 with 47 cases according to occurrence of FGR), and Civil Aviation Clinical Medical College of Peking University (plain region, control group with 71 cases) were enrolled in this study. All pregnant women in each group underwent fetal color Doppler ultrasound examination of the middle cerebral artery (MCA) and umbilical artery (UA) blood flow parameters, including pulsatility index (PI), resistance index (RI), systolic/diastolic ratio (S/D), peak systolicvelocity (PSV), and cerebroplacental ratio (CPR) at 28 weeks of gestation were detected. Multivariate Logistic regression analysis was performed to identify independent risk factors for FGR in pregnant women with gestational hypertension. Receiver operating characteristic (ROC) curves were plotted to analyze the predictive value of color Doppler parametersfor FGR. Results The UA blood flow parameters (PI, RI, S/D, PSV) of the fetuses in groups A1, A2, B1, and B2 were significantly higher than those in the control group, while the MCA blood flow parameters (PI, RI, S/D, PSV) and CPR were significantly lower (P < 0.05). Among the five groups, group B1 had the highest UA blood flow parameters (PI, RI, S/D, PSV) and the lowest MCA blood flow parameters (PI, RI, S/D, PSV) and CPR (P < 0.05). Multivariate Logistic regression analysis revealed that high altitude of residence and umbilical cord abnormalities were independent risk factors for FGR in pregnant women with gestational hypertension (P < 0.05). ROC curve analysis showed that the areas under the curves for the combined prediction of FGR in pregnant women with gestational hypertension at altitudes of 2, 300 meters and 3, 700 meters using color Doppler multi-parameters were 0.906 and 0.917, respectively, indicating a significantly higher predictive performance compared to individual parameter (P < 0.05). Conclusion Color Doppler ultrasound parameters of UA and MCA bloodflow during the second trimester of pregnancy demonstrate good predictive value for FGR induced by hypertensive disorders of pregnancy in high-altitude regions at different altitudes, and the predictive performance is even higher when multiple parameters are combined.

OBJECTIVE To compare the safety of high-dose methotrexate （HD-MTX） via peripherally inserted central catheter （PICC） and totally implantable venous access port （TIVAP） in pediatric patients with malignant brain tumors. METHODS Patients with malignant brain tumors who received HD-MTX via PICCs or TIVAPs in our hospital from July 2018 to April 2022 were retrospectively analyzed. Clinical data were collected to compare differences in blood concentration of methotrexate （MTX），the incidence of adverse events （including adverse drug reactions and catheter-related complications） and length of stay in hospital. Multivariate linear regression was applied to analyze the factors that influenced the blood concentration of MTX. RESULTS A total of 107 patients were included in the study，with 65 patients in the PICC group and 42 patients in the TIVAP group. Blood concentration of MTX at 24 h （C24 h） in TIVAP group was significantly higher than PICC group （[ 126.87±61.99） μmol/L vs. （102.45±48.77） μmol/L，P＜0.05）. There was no significant difference in blood concentration of MTX at 42 h （C42 h），compared with PICC group （P＞0.05）. Results of multivariate linear regression analysis showed that TIVAP was associated with the increase of C24 h（P＜0.05）. No significant differences were observed in the incidence of adverse events and the length of stay in the hospital between 2 groups （P＞0.05）. CONCLUSIONS Risk of adverse events is not increased，although the MTX C24 h level is elevated after administration of TIVAP. TIVAP is a safe choice for HD-MTX therapy with implementing therapeutic drug monitoring.

Objective: To explore the relationship between isotemporal substitution of 10 min/d of vigorous physical activity (VPA), moderate physical activity (MPA), walking, sedentary behavior (SB) and sleep (SLP) and depression among vocational school students with different duration of moderate-to-vigorous physical activity (MVPA), so as to provide time allocation suggestions for reducing depression levels. Methods: The convenient cluster sampling method was adopted to conduct a questionnaire survey among 8 149 grade one to grade three students in 14 vocational schools in Shanghai and Jiangsu Province from December 2021 to January 2022. According to whether the MVPA reached 60 min/d, the vocational school students were divided into the MVPA standard group and the MVPA non-standard group, and the isotemporal substitution model was used for analysis. Results: About 19.81% of students were in the MVPA standard group. In the MVPA non-standard group, substituting MPA for all other studied behaviors and substituting SLP for walking and SB were negatively correlated with depression ( β =-0.78, -0.90, -0.88, -0.83; -0.07 , -0.05, P <0.05), and the association of MPA substitution was much greater than that of SLP substitution. In the MVPA standard group, replacing VPA, walking and SB with SLP were all negatively associated with depression ( β =-0.23, -0.12, -0.10 ), whereas replacing MPA, SB and SLP with VPA was all positively associated with depression ( β =0.15, 0.13, 0.23) ( P <0.05). Conclusion The MVPA level of vocational school students is low. The effects of isotemporal substitution for VPA and MPA are different when MVPA duration is up to standard and when MVPA duration is not up to standard. Appropriate time allocation suggestions should be provided based on the characteristics of adolescents with different MVPA durations.

Objective To explore the diagnostic value of color Doppler ultrasound for fetal intrauterine distress(FIUD)in high-risk puerperae in plateau areas.Methods A total of 130 puerperae in plateau areas and 130 puerperae in plain areas were enrolled.According to presence or absence of FIUD in different areas,they were divided into the plateau distress group(47 cases),the plateau normal group(83 cases),the plain distress group(31 cases)and the plain normal group(99 cases).All cases underwent blood flow detection of middle cerebral artery(MCA)and umbilical artery(UA)before delivery,and cerebral-placental ratio(CPR)was calculated.The incidence of FIUD was compared between high-risk puerperae in plateau area and in plain area.Gestational age,birth weight,cesarean section rate and blood spectrum parameters of MCA and UA were compared between the four groups.The predictive value of color Doppler ultrasound parameters for FIUD was analyzed by receiver operating characteristic(ROC)curves.Results The incidence rates of FIUD and severe FIUD were higher in patients of plateau areas than those in plain areas(36.15%,13.85%vs.23.85%,4.62%,P＜0.05).Compared with the plateau distress group,gestational age and birth weight were increased in the plateau normal group and the plain distress group(P＜0.05).Compared with the plateau distress group,PI,RI,S/D and CPR of MCA were increased,while PI,RI and S/D of UA were decreased in the plateau normal group and the plain distress group(P＜0.05).Results of ROC curve analysis showed that overall performance advantage of S/D of UA was the most obvious in the diagnosis of FIUD in high-risk puerperae in plateau areas.The diagnostic sensitivity of RI of MCA was the highest,and the diagnostic specificity of CPR was the highest(P＜0.05).Conclusion Color Doppler ultrasound has good diagnostic value for FIUD in high-risk puerperae in plateau areas,which can be applied as an effective clinical screening means for FIUD.

BACKGROUND: The previous study has indicated that lung cancer has a high incidence and mortality in China, and has caused a large economic burden. The purpose of this study was to analyze the incidence and economic burden of lung cancer by analyzing the information on the home page of discharge history of lung cancer patients in Hebei Tumor Hospital, and to provide scientific basis for the prevention and treatment of lung cancer. METHODS: The information of all of the discharges, new cases, surgical patients, age, gender, length of stay and hospitalization cost of lung cancer patients in Hebei Tumor Hospital from January 2012 to December 2019 were retrieved based on the medical record management system, and the incidence trend, gender and age distribution as well as the economic burden of the disease were statistically described. RESULTS: The number of new cases of lung cancer increased year by year, from 2,235 cases in 2012 to 5,012 cases in 2019. The number of males always outnumbered females, but the gender ratio decreased year by year, from 2.25 in 2012 to 1.56 in 2019. Among new cases of lung cancer, the proportion of surgical treatment increased year by year, from 28.14% in 2012 to 44.83% in 2019. Except for 2012, the proportion of surgical operations in female patients was higher than that in male patients from 2013 to 2019. The proportion of surgical operations in male and female patients was 23.52% and 28.07% in 2013, and 36.14% and 58.37% in 2019, respectively. The median age at the onset of lung cancer has increased year by year, from 61 years old in 2012 to 63 years old in 2019. The median age of onset in all lung cancer patients was higher in males than in females. The number of new lung cancer patients and surgical patients both showed an increasing trend with the increase of age, and both reached the maximum value in the age group of 60-69 years old. With the increase of age, the number of patients gradually decreased. The median length of hospital stay for all discharged lung cancer patients or surgical patients decreased year by year, from 10 d and 19 d in 2012 to 8 d and 17 d in 2019, respectively, while the median hospitalization cost increased year by year. It increased from 10,611.46 yuan and 38,750.13 yuan in 2012 to 17,187.15 yuan and 84,030.16 yuan in 2019, respectively. CONCLUSIONS Lung cancer is still one of the main cancers endangering the health of Chinese residents. The incidence of lung cancer is increasing year by year, and the distribution of gender and age has certain characteristics. In order to reduce the number of cases and the economic burden, effective prevention and control measures should be formulated and medical reform should be strengthened.
