Objective: To analyze the trends of the frequency of meat, egg, and milk consumption among rural primary and junior high school students in central and western China covered by the Nutrition Improvement Program for Rural Compulsory Education Students (NIPRCES) from 2015 to 2023, so as to provide basis for formulating more targeted nutrition intervention policies and health education strategies. Methods: Using data from six rounds of monitoring and evaluation (2015-2021 and 2023), the study included 323 870 students from grade 3 to 9 across 22 provinces (autonomous regions and municipalities) in central and western China. The consumption frequencies of meat, egg, and milk over the past week were collected via questionnaires. The Cochran-Armitage trend test was used to analyze temporal trends, and multivariable Logistic regression models were employed to analyze factors associated with the frequency of meat, egg and milk consumption and to test for interaction effects between the year and gender, region, and grade level. Results: From 2015 to 2023, the proportion of students consuming meat, egg, and milk ≥1 time/day increased from 23.20 %, 10.71%, and 0.74% to 35.53%, 22.09%, and 26.63%, respectively. Trend tests indicated a significant upward trend for the daily intake of all three food categories for meat, egg and milk over the years ( Z =67.18, 64.90, 93.14, all P <0.01). Multivariable Logistic regression analysis showed that the daily meat intake was lower in the central region than in the western region ( OR=0.77, 95%CI =0.76-0.78), whereas the daily intake of eggs ( OR=1.19, 95%CI =1.17-1.22) and milk ( OR= 1.27 , 95%CI =1.24-1.29) was higher in the central region (all P <0.05). Compared with grade 3-4 students, junior high school students had lower daily intake of meat, eggs, and milk≥1 time/day ( OR =0.95, 0.77, 0.77, all P <0.05), with a declining trend as grade increased. Girls also had lower daily intake of meat, eggs, and milk ≥1 time/day than boys ( OR =0.95，0.93，0.91, all P < 0.05). Significant interactions were observed between year and region, as well as between year and grade (all P <0.05). Conclusion From 2015 to 2023, the NIPRCES improved the intake level of among rural students, but the situation of relatively insufficient intake of egg and milk among females, junior high school students and those in the western region still exists.

Objective:To assess the feasibility and efficacy of transperineal laser ablation(TPLA)with single laser fiber in treating benign prostatic obstruction(BPO).Methods:From April 2021 to March 2024,a total of 13 BPO patients were selected from Beijing Friendship Hospital.TPLA was performed using a single laser fiber,which was guided by transrectal biplane ultrasound.The single laser fiber was used to undergo TPLA under the guidance of trans-rectal dual-plane ultrasound.The intraoperative time,ablation time,energy consumption,indwelling time of catheter,and complications were observed.The postoperative 6 months was chosen as the cut-off point of follow-up,and the pre and postoperative changes of international prostate symptom score(IPSS),quality of life index(QoL),prostate volume(PV),residual urine volume(RUV)and the maximum urine flow rate(Qmax)were compared.Results:All 13 patients successfully underwent TPLA with single laser fiber.The average operation time was(55.1±18.3)min,and the average ablation time was(16.3±1.7)min,and average energy consumption was(3951.6±459.7)J,and the median value of indwelling time of catheter was 7(7,10)days.The number of postoperative complication was 2 cases,and both them belonged to Clavien-Dindo grade II complication.At the postoperative 6th month,the IPSS,QoL,PV,Qmax and RUV of all patients were improved,all of which were better than preoperative these indicators,and the differences were significant(t=12.102,-3.228,-3.181,-2.581,-2.936,P<0.05).Conclusion:The application of single laser fiber in conducting TPLA operation is feasibility at technical aspect,and it can achieve the therapeutic goals of improving patients'symptoms and enhancing their quality of life.Although its operational time is slightly longer than that of using multiple fibers simultaneously,it can effectively reduce the cost of expenditure for consumables.

Objective To explore the effect of Roy's adaptive model nursing on the rehabilitation in patients with multiple myeloma.Methods Eighty patients with multiple myeloma who were treated in Huaibei Miners General Hospital from October 2018 to October 2021 were selected by convenient sampling.They were divided into two groups by random number table method,with 40 patients in each group.Routine nursing was applied in the control group,and Roy's adaptive model nursing was given to the study group.The nutritional status,psychological resilience and lifestyle improvement were compared between the two groups.Results Before nursing,there was no significant difference in the nutritional indicators,Connor-Davidson Resilience Scale(CD-RISC)score,or Health-Promoting Lifestyle Scale(HPLP Ⅱ)score between the two groups(P>0.05).After nursing,body mass index(BMI),triceps skinfold thickness(TSF),albumin(ALB)and prealbumin(PA),the scores of toughness,strength and optimism in CD-RISC,and the scores of interpersonal relationship,nutrition management,health responsibility,exercise management,stress management and mental growth in HPLP Ⅱ were increased in both groups(P<0.05),and these indexes in the study group were significantly higher than those in the control group(P<0.05).Conclusion Roy's adaptive model nursing can improve nutritional status,enhance psychological resilience and promote healthy lifestyle of patients with multiple myeloma.

Background Prior epidemiological studies suggest that exposure to pyrethroid insecticides may adversely affect children’s respiratory health. However, only limited studies are currently available on this topic in China. Objective To explore the association between exposure to pyrethroid insecticides and pulmonary function in children in Shanghai. Methods From August 2019 to January 2020, a cross-sectional study was conducted, recruiting 163 healthy school-aged children (aged 5–12 years) from Shanghai Children’s Hospital, Shanghai Jiao Tong University School of Medicine. Basic information, including age, height, weight, and family income, was collected. Urine samples from the children were collected and were analyzed for the levels of three pyrethroid insecticide metabolites: 3-phenoxybenzoic acid (3-PBA), cis-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane carboxylic acid (CDCCA), and trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane carboxylic acid (TDCCA). Gas chromatography-tandem mass spectrometry (GC-MS/MS) was used for the analysis. Spirometry was used to assess pulmonary function and recorded following parameters: peak expiratory flow (PEF), forced expiratory flow between the 25th and 75th percentiles of forced vital capacity (FEF_25-75), forced expiratory volume in one second (FEV₁), forced vital capacity (FVC), and FEV₁/FVC. Multiple linear regression and restricted cubic spline models were used to evaluate the associations between urinary pyrethroid insecticide metabolite levels and pulmonary function parameters. Results The study included 163 school-aged children, with an average age of (7.04 ± 2.08) years and an average body mass index (BMI) of (16.04 ± 2.72) kg·m⁻²; 75 (46.01%) of the participants were boys. The detection rates of 3-PBA, TDCCA, and CDCCA in urine were 85.28%, 17.79%, and 4.91%, respectively. The median creatinine-adjusted 3-PBA concentration was 0.150 μg·g⁻¹. After adjusting for confounders such as height, BMI, sex, age, delivery mode, annual family income, and maternal education level, the multiple linear regression model showed that urinary 3-PBA levels were negatively associated with both FVC [β=−0.030, 95% confidence interval (CI): −0.058, −0.003; P=0.031] and FEV₁ (β=−0.032, 95%CI: −0.064, 0.000; P=0.04998). The final restricted cubic spline model showed a nonlinear association between urinary 3-PBA levels and FVC, FEV₁, PEF, and FEF_25-75（P for nonlinear < 0.05；P for overall < 0.05）. Conclusion The level of pyrethroid insecticide exposure in school-aged children in Shanghai is relatively high. The urinary 3-PBA concentration is negatively associated with pulmonary function, indicating potential adverse effects of pyrethroid insecticide exposure on respiratory health of school-aged children.

Objective To investigate the effects of Naoluo Xintong Decoction(NLXTD)on proliferation of rat brain microvascular endothelial cells(BMECs)after oxygen-glucose deprivation/reoxygenation(OGD/R)injury and role of the HIF-1α/VEGF pathway in mediating its effect.Methods Using a BMEC model of OGD/R,we tested the effects of 10%NLXTD-medicated rat serum,alone or in combination with 2ME2 or 10%NAKL,on cell proliferation,migration,tube-forming ability and permeability using CCK-8 assay,Transwell chamber assay,tube formation assay and permeability assay.Cellular expressions of VEGF and Notch were detected using ELISA and laser confocal immunofluorescence analysis,and the expressions of HIF-1α,VEGFR2,Notch1,ERK and P-ERK1/2 proteins were detected with Western blotting.Results OGD/R injury significantly decreased viability of BMECs.NLXTD treatment of the cells with OGD/R could significantly promoted cell proliferation,migration and tube formation ability,but these effects were strongly attenuated by application of 2ME2.NLXTD treatment also significantly increased the percentages of VEGF-and Notch-positive cells in the cell models and obviously enhanced the expression levels of HIF-1α,VEGFR2,Notch1 and P-ERK1/2.Conclusion NLXTD promotes proliferation,migration,and tube formation of rat BMECs after OGD/R injury possibly by activating the HIF-1α/VEGF signaling pathway.

Objective To observe the value of T2 mapping for quantitatively evaluating the changes of junctional zone and outer myometrium caused by endometrial fibrosis.Methods A total of 73 infertility patients with endometrial fibrosis confirmed by hysteroscopy(disease group)and 33 healthy women of childbearing age(control group)were prospectively enrolled,and MR examinations were performed at the late proliferative phase of endometrium.The thickness and T2 value of junctional zone,T2 value of outer myometrium on anterior,posterior and fundus wall of midsagittal corpus uteri were measured,and the mean value of the above measurements on the three walls were calculated.Receiver operating characteristic curves were constructed,the areas under the curves(AUC)were calculated to explore the efficacy of those with significant difference among the mean thickness and the mean T2 value of junctional zone,the mean T2 value of outer myometrium and their combination for evaluating endometrial fibrosis.Results The thickness and T2 value of anterior wall,posterior wall,fundus wall and the mean junctional zone in disease group were all significantly higher than those in control group(all P＜0.001).No significant difference of T2 value of anterior wall,posterior wall,fundus wall nor the mean outer myometrium was found between groups(all P＞0.05).The mean thickness and the mean T2 value of junctional zone and their combination could be used to effectively evaluate endometrial fibrosis,with AUC of 0.839,0.822 and 0.922,respectively,and their combination had the best performance(both P＜0.01).Conclusion T2 mapping could be used to quantitatively evaluate the injury of junctional zone caused by endometrial fibrosis.

Objective:To investigate the correlation between leucine-rich α2 glycoprotein (LRG) and endoscopic activity in patients with Crohn′s disease (CD), based on the assessment of inflammation in small intestinal lesion by double-balloon enteroscope (DBE).Methods:From 15 August 2022 to 22 August 2023, the clinical data of 139 patients with small bowel CD diagnosed by DBE at the First Affiliated Hospital of Anhui Medical University were prospectively collected, which included fecal calprotectin (FC), C-reactive protein (CRP), white blood cell count, hemoglobin, albumin, Crohn′s disease activity index (CDAI), and simple endoscopic score for Crohn′s disease (SES-CD). According to the SES-CD, endoscopic activity was classified as mucosal healing (0), endoscopic remission (0 to 2), mild activity (3 to 6), moderate activity (7 to 15), and severe activity (≥16). LRG levels were detected in all patients. Spearman rank correlation was used to analyze the correlation between LRG, clinical biochemical parameters and endoscopic scores. Receiver operating characteristic curve (ROC) was performed to determine the optimal cut-off value of LRG for evaluating endoscopic mucosal healing. Mann-Whitney U test, Kruskal-Wallis H test, and Bonferroni corrected test were used for statistical analysis. Results:Among 139 patients with small bowel CD, the LRG level was 17.3 (13.0, 25.2) mg/L, and SES-CD was 5 (1, 9); 32 patients achieved mucosal healing, 50 patients achieved endoscopic remission; 39 patients had mild activity, 40 patients had moderate activity, and 10 patients had severe activity. The SES-CD was negatively correlated with both hemoglobin and albumin ( r=-0.177 (95% confidence interval, 95% CI: -0.334 to -0.011), -0.293 (95% CI: -0.438 to -0.133)), with statistical significance ( P=0.037, <0.001). The SES-CD was positively correlated with CRP, CDAI, LRG and FC ( r=0.344 (95% CI: 0.188 to 0.482), 0.429 (95% CI: 0.282 to 0.556), 0.525 (95% CI: 0.393 to 0.636), 0.661 (95% CI: 0.556 to 0.745)), with statistical significant (all P<0.001). For the 64 small bowel CD patients with CRP in the normal reference value, SES-CD was positively correlated with CDAI, LRG and FC ( r=0.296 (95% CI: 0.054 to 0.505), 0.364 (95% CI: 0.129 to 0.559), 0.547 (95% CI: 0.348 to 0.699)), with statistical significance ( P=0.017, =0.003, <0.001). The LRG level of patients with endoscopic mucosal healing was significantly lower than that of patients with endoscopic remission (11.5 (10.1, 17.2) mg/L vs. 17.3 (13.4, 23.5) mg/L), with statistical significance ( Z=-3.25, P<0.001). ROC analysis showed that the area under the curve (AUC) of LRG in predicting endoscopic mucosal healing was 0.81 (95% CI: 0.73 to 0.89), with an optimal cut-off value of 15.27 mg/L. The sensitivity, specificity, positive predictive value and negative predictive value were 0.757, 0.718, 0.900 and 0.469, respectively. The accuracy of the combination of LRG and FC (AUC was 0.88, 95% CI: 0.82 to 0.94) in predicting endoscopic mucosal healing was higher than that of LRG alone (AUC was 0.81, 95% CI: 0.73 to 0.89), and the difference was statistically significant ( P=0.011). Conclusion:Based on the results of DBE, LRG may be a reliable biomarker for predicting endoscopic remission and mucosal healing in patients with small bowel CD.

Objective To explore the effect of life reconstruction training on anxiety and depression among individuals with chronic spinal cord injury(SCI)and their caregivers,and to analyze the influencing factors.Methods A total of 216 SCI patients and 79 caregivers who participated in life reconstruction training were recruited from the Hope House for SCI individuals in Shanghai Yangzhi Rehabilitation Hospital from May,2017 to Octo-ber,2019.They were assessed with Self-Rating Anxiety Scale(SAS)and Self-Rating Depression Scale(SDS)be-fore and after intervention.Results After intervention,the scores of SAS and SDS decreased(P<0.05)in both SCI patients and their caregivers.SAS scores were more likely to reduce in SCI patients who suffered anxiety at admission(OR=2.315,95%CI 1.328 to 4.033,P=0.003)and their caregivers(OR=3.632,95%CI 1.270 to 10.390,P=0.016),as well as non-agricultural-registered SCI patients(OR=1.908,95%CI 1.074 to 3.391,P=0.028).Being unmarried,having an injury duration≥21 years,injury due to disease,and having depression at admission significantly promoted the reduction in SDS scores among SCI patients(P<0.05).Caregivers with a junior-high-school education or less were more likely to experience reductions in scores of SAS and SDS compared with those with higher education(P<0.05).Caregivers with five to 15 years of caregiving experience achieved more anxiety reduction(OR=7.155,95%CI 1.806 to 28.342,P=0.005).Conclusion Life reconstruction training is effective on anxiety and depression among individuals with chronic SCI and their caregivers.It is recommended to prioritize anxiety interventions for patients with rural household registra-tion in China,along with depression management for the married/divorced/widowed individuals,with<21 years since injury,and trauma-induced lesions.For caregivers,it is needed to focus to anxiety and depression in better-educated individuals,as well as anxiety in those with either<5 or≥15 years of caregiving experience.

The clinical pharmacist was involved in the whole process of drug treatment and monitoring of a patient with ulcerative colitis(UC)and facial aseptic abscesses.After admission,clinical pharmacists and physicians jointly formulated an empirical anti-infection plan for meropenem and linezolid glucose injection.After the 5th day of medication,the patient continued to have high fever.After discussion with the physician and clinical pharmacist,it was considered that the patient's facial boil was caused by aseptic abscess syndrome,and UC with extraintestinal manifestations could not be ruled out.Hydrocortisone succinate sodium was added intravenously.After the 9th day of treatment,the patient's facial abscesses improved.Subsequently,the physician followed the clinical pharmacist's advice and used infliximab as the subsequent treatment plan.After the 11th day of treatment,the patient's symptoms improved significantly.During the 2-month follow-up,the facial abscesses completely disappeared,the stool was normal,and there were no special discomforts.The participation of clinical pharmacists in clinical practice improves patients' understanding of the disease and treatment compliance,providing patients with individualized medication support to ensure the safety and effectiveness of medication.

OBJECTIVES: To investigate the effects of Naoluo Xintong Decoction (NLXTD) on proliferation of rat brain microvascular endothelial cells (BMECs) after oxygen-glucose deprivation/reoxygenation (OGD/R) injury and role of the HIF-1α/VEGF pathway in mediating its effect. METHODS: Using a BMEC model of OGD/R, we tested the effects of 10% NLXTD-medicated rat serum, alone or in combination with 2ME2 or 10% NAKL, on cell proliferation, migration, tube-forming ability and permeability using CCK-8 assay, Transwell chamber assay, tube formation assay and permeability assay. Cellular expressions of VEGF and Notch were detected using ELISA and laser confocal immunofluorescence analysis, and the expressions of HIF-1α, VEGFR2, Notch1, ERK and P-ERK1/2 proteins were detected with Western blotting. RESULTS: OGD/R injury significantly decreased viability of BMECs. NLXTD treatment of the cells with OGD/R could significantly promoted cell proliferation, migration and tube formation ability, but these effects were strongly attenuated by application of 2ME2. NLXTD treatment also significantly increased the percentages of VEGF- and Notch-positive cells in the cell models and obviously enhanced the expression levels of HIF-1α, VEGFR2, Notch1 and P-ERK1/2. CONCLUSIONS NLXTD promotes proliferation, migration, and tube formation of rat BMECs after OGD/R injury possibly by activating the HIF-1α/VEGF signaling pathway.
