With the establishment of bio-psycho-social medical model,both social and psychological factors play an important role in the occurrence,development and treatment of diseases.Hypertension is a common chronic multiple disease in China,and patients are often complicated with depression and other e-motional disorders.The interaction between hypertension and depression significantly increases the risk of poor prognosis.Current studies have shown a bidirectional promoting relationship between hypertension and depression,and they have some com-mon pathogenesis.However,the specific mechanism of their co-morbidity has not been fully elucidated.Renin-angiotensin sys-tem(RAS)plays an important role in the regulation of hyperten-sion and depression and other emotions.It is composed of two antagonistic pathways.The balance is maintained by angioten-sin-converting enzyme 2(ACE2).Therefore,this article reviews the relationship and mechanism of RAS in hypertension,depres-sion and comorbid states,in order to provide new treatment ide-as for hypertension and depression.

Objective To explore the effect and predictive value of ultrasound-guided needling assisted motor evoked potentials(MEP)and electromyography(EMG)monitoring on neurological recovery in spinal surgery.Methods A retrospective analysis was conducted on the clinical data of 80 patients who underwent spinal surgery at Jiangsu Province Hospital of Chinese Medicine from January 2020 to December 2024.A total of 41 patients in the observation group received ultrasound-guided needling assisted MEP and EMG monitoring,and 39 patients in the control group received conventional method for MEP and EMG monitoring.The operative time,intraoperative blood loss,and the proportions of intraoperative MEP and EMG warnings were compared between the two groups,and the sensitivity and specificity of intraoperative MEP monitoring were compared between the two groups.The receiver operating characteristic(ROC)curve was plotted,and the area under the curve(AUC)was calculated to analyze the efficiency of MEP warning in predicting the dysfunction of postoperative spinal cord.Results There were no significant differences in the operative time,intraoperative blood loss,or the proportions of intraoperative MEP and EMG warnings(P>0.05).The sensitivity,specificity and AUC of intraoperative MEP monitoring in the observation group were significantly higher than those in the control group,with statistically significant differences(P<0.05).The sensitivity,specificity,and AUC of postoperative MEP warning in predicting the dysfunction of spinal cord in the observation group were higher than those in the control group,with statistically significant differences(P<0.05).Conclusion Ultrasound-guided needling assisted MEP and EMG monitoring can effectively enhance the intraoperative neural monitoring accuracy,and postoperative MEP warning demonstrates superior predictive value for postoperative neurological dysfunction.

Objective:To compare the medical costs of using standard fortified donor human milk (DHM) or preterm formula (PF) to supply very low birth weight [VLBW, defined as birth weight (BW) ≥1 000 g but <1 500 g] and extremely low birth weight (ELBW, defined as BW <1 000 g) premature infants with insufficient maternal breast milk.Methods:VLBW and ELBW preterm infants hospitalized in Peking Union Medical College Hospital from September 2017 to October 2020 were retrospectively enrolled and assigned into DHM group and PF group based on complementary feeding methods. The cost of parenteral nutrition (PN), cost of antibiotics, and total medical expenses during hospitalization were compared between the two groups.Results:A total of 89 infants were enrolled in this study, out of whom 50 was in the DHM group and 39 the PF group. The gestational age in DHM group and PF group were both (29±2) weeks. The BW of DHM group was 1 170 (919, 1 380)?g and that of PF group was 1 170 (1 010, 1 360) g. There were no significant differences in gestational age, BW, maternal age at delivery, delivery mode, gender ratio, proportion of small-for-gestational-age infants and length of hospital stay between the two groups (all P>0.05). The cost of parenteral nutrition in DHM group was significantly lower than that in PF group [3 500 (1 922, 5 704) Chinese yuan vs 7 995 (5 579, 10 788) Chinese Yuan, P<0.01]. The cost of antibiotics in DHM group was significantly lower than that in PF group [6 529 (2 265, 10 860) Chinese Yuan vs 13 676 (10 480, 18 506) Chinese Yuan, P<0.01]. The difference in total medical expense during hospitalization showed no statistical significance between two groups ( P>0.05). Amorg VLBW preterm infants, the cost of PN, cost of antibiotics, total cost of hospitalization, and daily cost of hospitalization in HDM group was significantly lower than that in PF group (all P<0.05). In ELBW preterm infants, the cost of PN and the cost of antibiotics in HDM group were significantly lower than that in PF group (both P<0.05), but the total cost of hospitalization and the daily cost of hospitalization between two groups showed no significant difference (all P>0.05). Conclusions:When mother's own milk is insufficient, using donor human milk reduces the costs of PN and antibiotics in VLBW and ELBW preterm infants compared with using PF. In VLBW preterm infants, using DHM can also reduce the total and daily cost of hospitalization.

Objective:To analyze the predictive role of WT1 expression levels pre-and early post-transplantation on relapse and overall survival(OS)in patients with acute myeloid leukemia(AML)undergoing allogeneic hematopoietic stem cell transplantation(allo-HSCT)during their first complete remission(CR1).Methods:A retrospective analysis was conducted on the clinical data of 107 adult AML patients who underwent allo-HSCT during their CR1 at our center between May 2012 and December 2021.The predictive role of bone marrow WT1 expression levels before transplantation and at 3 and 6 months post-transplantation on relapse and OS was explored in combination with relevant clinical factors.Results:The median follow-up time for the 107 patients was 70(range:11-117)months.Among the patients,15 cases died.Kaplan-Meier survial analysis showed that the 3-year overall survival(OS)rate was 85.0％.20 patients experienced relapse,with a median time to relapse of 8(range:0.5-44)months and a l-year cumulative relapse rate of 13.1％.The overall median value of WT1 before transplantation,3 months after transplantation,and 6 months after transplantation was 0.26％(range:0％-23.64％),with an upper quartile value of 0.74％.No statistically significant differences in WT1 expression levels were observed among the pre-transplantation,3-month post-transplantation,and 6-month post-transplantation time points(P=0.227).Univariate analysis showed that patients with WT1 levels＞0.74％at 3 months post-transplantation had a higher 1-year relapse rate(P=0.029)and lower 3-year OS rate(P＜0.001)compared to patients with WT1 levels ≤0.74％.Other significant factors affecting 1-year relapse included stem cell source(P=0.041)and chronic graft-versus-host disease(cGVHD)(P=0.013).For 3-year OS,additional influencing factors were genetic high risk(P=0.048)and stem cell source(P=0.016).Multivariate analysis revealed that WT1 level＞0.74％at 3 months post-transplantation had a trend to affect 1-year relapse rate(HR=3.309,95％CI:0.958-11.431,P=0.058),while the absence of cGVHD was an independent risk factor for 1-year relapse(HR=3.473,95％CI:0.749-16.100,P=0.037).Only WT1 level＞0.74％at 3 months post-transplantation was an independent risk factor for 3-year OS(HR=6.886,95％CI:2.402-19.738,P＜0.001).Conclusion:High WT1 expression level at 3 months post-transplantation in AML patients undergoing allo-HSCT during CR1 affects the 1-year relapse rate and 3-year OS,and is an independent risk factor affecting 3-year OS.These findings suggest that dynamic monitoring of WT1 expression levels has certain value in prognostic assessment of AML patients who received allo-HSCT during CR1.

Objective:To explore the correlation between intrahepatic cholestasis of pregnancy(ICP)and ad-verse pregnancy outcomes.Methods:A total of 511 singleton pregnant women with ICP treated at The Third Affili-ated Hospital of Guangzhou Medical University from August 2017 to January 2024 were selected as the study sub-jects.Among them,patients were divided into the adverse pregnancy outcome group(n=49)and the control group without adverse pregnancy outcomes(n=462).The general and clinical data of the two groups were com-pared and analyzed.Results:①General situation:The number of pregnancies and deliveries,ICU transfer rate,total hospital stay,and total hospitalization costs were significantly higher in the adverse pregnancy outcome group compared to the control group(P<0.05).The number of prenatal check-ups,diagnostic gestational weeks,and gestational weeks at delivery were significantly lower compared to the control group(P<0.05).②Clinical symp-toms:The incidence of itching in the adverse pregnancy outcome group was lower compared to the control group(10.2%vs.26.6%,P<0.05),while other symptoms such as rash,fatigue,jaundice,and gastrointestinal symp-toms showed no significant difference between the two groups(P>0.05).③Laboratory examinations:Compared with the control group,patients in the adverse pregnancy outcome group had significantly the increased levels of alanine aminotransferase,aspartate aminotransferase,uric acid,urea nitrogen,and triglycerides,and significantly the decreased levels of alkaline phosphatase and fasting blood glucose,with statistical significance(P<0.05).Other biochemical indicators showed no significant difference between the two groups(P>0.05).④ICP grading and complications:The proportion of early-onset ICP,severe and very severe ICP in the adverse pregnancy out-come group was significantly higher compared to the control group(P<0.001);the proportion of adverse preg-nancy outcome group with pregnancy-induced hypertension was significantly higher compared to the control group;the incidence of preterm birth,fetal growth restriction,meconium-stained amniotic fluid,and fetal distress in the adverse pregnancy outcome group was significantly higher compared to the control group(P<0.001).⑤Neo-natal outcomes:The neonatal Apgar scores(1 min,5 min,10 min)and neonatal weight in the adverse pregnancy outcome group were lower compared to the control group(P<0.001),and the incidence of mild neonatal asphyx-ia was significantly higher,with a statistically significant difference(P<0.001).Conclusions:The severity of ICP is closely related to the occurrence of adverse pregnancy outcomes.Therefore,it is clinically necessary to pay at-tention to the grading of ICP,closely monitor the levels of total bile acids and liver enzymes,and try to avoid ad-verse pregnancy outcomes,especially intrauterine fetal death.

Objective:To construct a scientific and reliable clinical teacher competency evaluation index system, and provide a reference for strengthening the construction of clinical teachers in teaching hospitals.Methods:Based on literature research and group discussion, the initial expert consultation questionnaire was constructed. Two rounds of expert consultation were conducted using the Delphi method to form the competency evaluation index system for clinical teachers in teaching hospitals. A hierarchy analysis was conducted using Python to calculate the weights of indicators.Results:The positive coefficients of the two rounds of expert consultation were 100.00% and 95.24%, respectively, and the expert authority coefficients were 0.843 and 0.862, respectively. The Kendall's coefficients of concordance for the first-, second-, and third-level indicators in the first round of expert consultation were 0.207, 0.152, and 0.191 ( P<0.001), respectively, and these coefficients in the second round of expert consultation were 0.271, 0.176, and 0.252 ( P<0.001), respectively. The final evaluation index system included 7 first-level indicators, 15 second-level indicators, and 43 third-level indicators. The first-level indicators included professional quality, professional knowledge and skills, medical education knowledge, teaching ability, communication and cooperation, teaching motivation, and career development, and their weights were 0.147, 0.149, 0.142, 0.147, 0.146, 0.134, and 0.136, respectively. Conclusions:The evaluation index system is comprehensive, scientific, and reliable. It can provide a reference for clinical teacher selection, evaluation, and training in teaching hospitals.

Objective:To investigate the detection and clinical features of human rhinovirus（HRV）infection in children from the Xiamen area.Methods:A retrospective analysis was conducted on children treated at Xiamen Children's Hospital from November 2021 to October 2022.Thirteen types of multiplex respiratory pathogen detection kits were used to screen for 13 common respiratory pathogens. Clinical data of HRV-positive hospitalized children were collected.Results:（1）Among 8 420 children with acute respiratory infections，HRV had the highest detection rate at 20.40%（1 718/8 420），followed by HMPV（10.12%），H3N2（7.46%），HRSV（6.94%），and HPIV（6.59%）.HRV was detected throughout the year，with the highest proportion in May（18.42%）.（2）Out of 1 718 children with HRV infection，863 cases were hospitalized for pneumonia（50.23%，863/1 718）.The median age of hospitalized children was 2.58（1.07，4.20）years old，with 53.77% under 3 years old.（3）The main clinical manifestations of HRV pneumonia were cough（97.68%，843/863），fever（58.05%，501/863），runny nose（57.01%，492/863），nasal congestion（36.96%，319/863），and wheezing（24.33%，210/843）. The HRV pneumonia co-infection group showed statistically significant differences in fever and hospitalization days compared to the single HRV pneumonia infection group（all P<0.05）.（4）Compared to the common pneumonia group，the severe HRV pneumonia group showed statistically significant differences in fever，runny nose，wheezing and hospitalization days the CRP, PCT, LDH levels, and the number of antibiotic applications after hospitalization（all P<0.05）. Conclusion:HRV infection is detected year-round in Xiamen，pneumonia is common，with children under 3 years old being particularly susceptible.It is important to be alert to mixed infections or severe pneumonia.Clinical treatment should avoid unnecessary antibiotic use，actively and provide appropriate treatment.

Aim To explore the mechanism by which dioscin regulates IL-17+γδT cells in the treatment of arthritis.Methods A collagen-induced arthritis(CIA)model was established in DBA/1 mice using bovine type Ⅱ collagen.The mice were randomly divid-ed into the CIA model group,methotrexate(MTX)positive control group,and dioscin low-dose(Dioscin-L),medium-dose(Dioscin-M),and high-dose(Dios-cin-H)groups.After intervention,the therapeutic effects were evaluated using scoring methods.Joint pathological damage was analyzed by hematoxylin and eosin(HE)staining.The levels of anti-collagen-spe-cific antibodies and the pro-inflammatory cytokine IL-17 were measured by ELISA.The expressions of γδT cells and their subtypes,as well as the secretion level of IL-17,were detected by flow cytometry.Results Dioscin significantly reduced the arthritis severity score in collagen-induced arthritis(CIA)mice,alleviated joint pathological damage,inhibited the production of IL-17 by splenic lymphocytes and the levels of anti-col-lagen-specific antibodies total IgG and IgG3,and de-creased the proportion of γδT cells in the lymph nodes,splenic γδT cells,and the Vδ4+T-cell subset.The level of IL-17 produced by the Vδ4 subtype in the lymph nodes of the intervention groups was lower than that in the model group,but the difference was not sta-tistically significant.Conclusion Dioscin has signifi-cant therapeutic effect on CIA,and its mechanism may be through the inhibition of γδT cells,but it is unlikely to be related to IL-17 derived from γδT cells.

Objective To explore the effect of exercise under cold exposure on hepatic protein ki-nase B(AKT)/forkhead box O1(FoxO1)expression in obese rats.Methods Among rats successfully induced nutritional obesity by high-fat diet,forty were selected and randomly divided into a normal-temperature control group(NC,n=10),a normal-temperature exercise group(NE,n=10),a sus-tained-cold control group(SC,n=10),and a sustained-cold exercise group(SE,n=10).The normal temperature was kept at 25°C±1°C,while the low temperature remained at 4°C±1°C,with 50%to 60%relative humidity.The exercise protocol was every other day at a speed of 25 m/min for 2 sets of 30 min each,with an interval of 10 minutes.After 5 weeks,glucose and insulin tolerance were tested by oral glucose tolerance test(OGTT)and insulin tolerance test insulin tolerance test(ITT).Then,all rats were weighed and sacrificed,then taken blood from the abdominal aorta to sepa-rate serum,followed by detection of serum alanine aminotransferase(ALT)and aspartate aminotransfer-ase(AST)levels using fully automatic biochemical analyzer.Moreover,livers were weighed to calcu-late the liver index.Meanwhile,the mRNA expressions of hepatic AKT,FoxO1 and PEPCK were de-tected using RT-qPCR,while the protein expressions of AKT,phosphorylated protein kinase B(p-AKT),and FoxO1 in the liver were measured using Western blotting.Results(1)The average body weights of the NE,SC and SE groups were significantly lower than the NC group(P<0.01),with that of the SC and SE groups significantly lower than the NE group(P<0.01).(2)Compared with the NC group,the area under the OGTT curve of the SC group decreased(P<0.01).Moreover,the area under the ITT curve of the SE group was significantly lower than the other 3 groups(P<0.01,P<0.01,P<0.05),with that of the NE and SC groups significantly lower than the NC group(P<0.05,P<0.01).(3)The liver indices of the NE,SC and SE groups were all significantly lower than the NC group(P<0.01),while the serum ALT level of the NE group was significantly lower than the NC and SE groups(P<0.05),with that of the SC group significantly lower than the NC group(P<0.01).(4)Compared with the NC group,hepatic AKT mRNA expression increased significantly in the SE group(P<0.05),while the hepatic FoxO1 and PEPCK mRNA expression decreased significantly in the other three groups(P<0.01).(5)Compared with the NC group,the liver AKT protein phosphorylation levels were significantly higher in the other three groups(P<0.05,P<0.05,P<0.01),while the FoxO1 protein expression decreased significantly(P<0.05,P<0.01,P<0.01).(6)Body mass,liver FoxO1,PEPCK mRNA expression,AKT protein phosphorylation level and FoxO1 protein expression level of obese rats were affected by cold exposure,exercise and cold exposure+exercise,and the liver index and serum ALT level were done by exercise and cold exposure+exercise.However,the area un-der the ITT curve and liver AKT mRNA content were impacted by cold exposure and exercise,while that under the OGTT curve was influenced by cold exposure and cold exposure+exercise.Conclu-sion Exercise under cold exposure can activate hepatic AKT/FoxO1 signaling pathway,protect liver function,increase insulin sensitivity,and effectively improve glucose metabolism in obese rats.
