Objective To investigate the prevalence status and influencing factors of metabolic syndrome (MS) in adult patients with hypopituitarism (HP) during hospitalization. Methods The data of adult HP patients who received treatment in the hospital were collected from March 2021 to March 2024. The prevalence status of MS in adult HP patients was counted, and logistic regression analysis was adopted to analyze the influencing factors of MS in adult HP patients. Results Among the 308 adult HP patients in this study, 121 cases developed MS and 187 cases did not develop MS, and they were included in the MS group (n=148) and the non-MS group (n=232). The incidence of MS in adult HP patients was 38.95% (148/380). Compared with the non-MS group, the levels of high-density lipoprotein cholesterol, serum total cholesterol and low-density lipoprotein cholesterol in the MS group were higher, the waist circumference was larger, and the growth hormone was lower (P<0.05). After logistic regression analysis, it was found that high-density lipoprotein cholesterol (OR=1.069, 95%CI: 1.010-1.132, P=0.021), total serum cholesterol (OR=1.065, 95%CI: 1.014-1.119, P=0.012), low-density lipoprotein cholesterol (OR=1.055, 95%CI: 1.005-1.108, P=0.031), waist circumference (OR=1.063, 95%CI: 1.006-1.123, P=0.030) and growth hormone (OR=1.077, 95%CI: 1.019-1.138, P=0.009) could independently affect the occurrence of MS in adult HP patients (P<0.05). Conclusion Adult HP patients during hospitalization are often complicated with MS. High-density lipoprotein cholesterol, serum total cholesterol, low-density lipoprotein cholesterol, waist circumference, and growth hormone are factors affecting the occurrence of MS in adult HP patients.

OBJECTIVES: To investigate the active ingredients in Hedyotis diffusa-Scutellaria barbata D. Don and the main biological processes and signaling pathways mediating their inhibitory effect on primary hepatocellular carcinoma (HCC). METHODS: The core intersecting genes of HCC and the two drugs were screened from TCMSP, Uniport, Genecards, and String databases using Cytoscape software, and GO and KEGG enrichment analyses of the intersecting genes were conducted. Molecular docking between the active ingredients of the drugs and the core genes was carried out using Pubcham, RCSB and Autoduckto to identify the active ingredients with the highest binding energy, whose inhibitory effect on HepG2 cells was verifies using CCK-8 assay, flow cytometry and Western blotting. RESULTS: TP53 and ESR1 were identified as the core genes of HCC and the two drugs. GO and KEGG analyses showed that the two genes were mainly involved in regulation of apoptotic signaling pathway, cell population proliferation, methane raft, and protein kinase activity, and participated in the signaling pathways of apoptosis, proteoglycans in cancer, PI3K Akt signaling pathway, and hepatitis B. Molecular docking studies showed that the active ingredients of the drugs could be docked with TP53 and ESR1 genes under natural conditions, and ursolic acid had the highest binding energy to ESR1 (-4.98 kcal/mol). The results of CCK-8 assay, flow cytometry and Western blotting all demonstrated significant inhibitory effect of ursolic acid on HepG2 cells. CONCLUSIONS The inhibitory effect of Hedyotis diffusa-scutellariae barbatae on HCC is mediated by multiple active ingredients in the two drugs.

Objective To investigate the characteristics of heart rate variability(HRV)in obese patients with severe obstructive sleep apnea hypopnea syndrome(OSAHS).Methods We retrospectively analyzed 78 patients with severe OSAHS diagnosed by polysomnography(PSG)in The Second Affiliated Hospital of Xi'an Jiaotong University from April 2018 to May 2022.According to body mass index(BMI),the patients were divided into obese with severe OSAHS group(43 cases)and non-obese with severe OSAHS group(35 cases).All patients received 24-hour Holter monitoring while on polysomnography monitoring.The differences in HRV indexes between the groups and the correlation between HRV and clinical indicators were analyzed.Results In terms of basic data and PSG indexes,the analysis results showed that compared with those in the non-obese OSAHS group,weight,BMI,neck circumference,waist circumference,and AHI in obese with severe OSAHS group were significantly higher,while the standard deviation of the 24-hour normal R-R interval(SDNN),the standard deviation of the 5-minute mean(SDANN),the triangle index(TI),the heart rate deceleration force(DC),the standard deviation of the normal R-R interval(awake SDNN),and high frequency during sleep in the obese with severe OSAHS group were significantly lower(P＜0.05).The correlation results showed that among obese with severe OSAHS patients,root mean square of the difference of adjacent R-R interval(rMSSD)was negatively correlated with the course of hypertension;TI and DC were negatively correlated with AHI.After adjusting for neck circumference and waist circumference,the linear regression analysis showed that SDNN,SDANN,and rMSSD were correlated with systolic blood pressure(P＜0.05).Conclusion There is significant decrease in HRV index in obese patients with severe OSAHS,suggesting that deterioration of cardiac autonomic nervous regulation function may increase the risk of cardiovascular disease.

Background::Bladder cancer, characterized by a high potential of tumor recurrence, has high lifelong monitoring and treatment costs. To date, tumor cells with intrinsic softness have been identified to function as cancer stem cells in several cancer types. Nonetheless, the existence of soft tumor cells in bladder tumors remains elusive. Thus, our study aimed to develop a microbarrier microfluidic chip to efficiently isolate deformable tumor cells from distinct types of bladder cancer cells.Methods::The stiffness of bladder cancer cells was determined by atomic force microscopy (AFM). The modified microfluidic chip was utilized to separate soft cells, and the 3D Matrigel culture system was to maintain the softness of tumor cells. Expression patterns of integrin β8 (ITGB8), protein kinase B (AKT), and mammalian target of rapamycin (mTOR) were determined by Western blotting. Double immunostaining was conducted to examine the interaction between F-actin and tripartite motif containing 59 (TRIM59). The stem-cell-like characteristics of soft cells were explored by colony formation assay and in vivo studies upon xenografted tumor models. Results::Using our newly designed microfluidic approach, we identified a small fraction of soft tumor cells in bladder cancer cells. More importantly, the existence of soft tumor cells was confirmed in clinical human bladder cancer specimens, in which the number of soft tumor cells was associated with tumor relapse. Furthermore, we demonstrated that the biomechanical stimuli arising from 3D Matrigel activated the F-actin/ITGB8/TRIM59/AKT/mTOR/glycolysis pathways to enhance the softness and tumorigenic capacity of tumor cells. Simultaneously, we detected a remarkable up-regulation in ITGB8, TRIM59, and phospho-AKT in clinical bladder recurrent tumors compared with their non-recurrent counterparts.Conclusions::The ITGB8/TRIM59/AKT/mTOR/glycolysis axis plays a crucial role in modulating tumor softness and stemness. Meanwhile, the soft tumor cells become more sensitive to chemotherapy after stiffening, that offers new insights for hampering tumor progression and recurrence.

Objective:There is a lack of scientifically validated tools to measure the knowledge attitude and practice(KAP)of informal caregivers for patients with pressure injury(PI).This study aims to develop a KAP Scale for Informal Caregivers of PI Patients and to evaluate its reliability and validity. Methods:Based on the KAP theory framework and relevant literature,an initial pool of items was created through expert brainstorming sessions.The initial scale was formed after a Delphi expert consultation and a preliminary survey.From April to October 2023,a convenient sample of informal caregivers for PI patients was recruited from an inpatient department of the Third Xiangya Hospital of Central South University,as well as its associated community and nursing homes.The first round included 186 participants,and the second round included 213 participants,who were used for item analysis and reliability and validity testing.After a 3-week interval,20 participants from the initial group were randomly selected for a retest to assess the test-retest reliability of the scale. Results:The KAP Scale for informal caregivers of PI patients consists of 3 dimensions with 19 items.The overall internal consistency(Cronbach's α)of the scale was 0.916.The item-level content validity index(I-CVI)ranged from 0.826 to 1.000,and the scale level-content validity index/average(S-CVI/Ave)was 0.94.Exploratory factor analysis extracted 3 common factors,accounting for 64.643％of the total variance.Confirmatory factor analysis showed that the model fit the data well,with x2/df=2.54,root mean square error of approximation(RMSEA)=0.085,comparative fit index(CFI)=0.920,and standardized root mean square residual(SRMR)=0.059. Conclusion:The KAP scale for informal caregivers of PI patients demonstrates good reliability and validity and can be used to assess the KAP levels of informal caregivers regarding PI.

Objective To observe the effects of different surgical approaches on the complications and tumor markers of patients undergoing radical resection of esophageal cancer.Method A prospective study was conducted on 100 patients with esophageal cancer who underwent radical surgery in our hospital from October 2019 to October 2022.They were randomly divided into an observation group and a control group using a random number table method,with 50 patients in each group,he right thoracic approach was used in the observation group and the left thoracic approach was used in the control group.Perioperative indexes,inflammatory factors[Substance P(SP),hypersensitive C-reactive protein(hs-CRP),interleukin6(IL-6)],tumor markers[cytokeratin 19 fragment antigen(CYFRA21-1),squamous cell carcinoma antigen(SCC-Ag)and carbohydrate antigen 199(CA199)]and lung function of the two groups were compared before and after surgery Indicators[vital capacity(VC),forced vital capacity(FVC),and forced expiratory volume in the first second(FEV1)]and complication rate.Result The operating time,blood loss,indwelling time,hospitalization time,and number of lymph node dissection in the observation group were(247.65±27.33)minutes,(211.82±25.49)ml,(6.97±2.12)days,(16.11±3.81)days,and(19.67±5.21),respectively,which were higher than those in the control group[(217.63±23.69)minutes,(175.67±22.13)ml,(5.43±1.80)days,(12.68±3.24)days,(15.45±4.12)](P＜0.05).On average,there was a significant increase in SP,hs CRP,and IL-6 levels in both groups 3 days after surgery(P＜0.05).The levels of SP,hs CRP,and IL-6 in the observation group were(273.96±35.45)ng/L,(11.35±2.12)mg/L,and(8.19±1.67)p.g/ml,respectively,which were lower than the control group[(298.33±38.42)ng/L,(14.29±2.68)mg/L,(10.35±1.82)pg/ml](P＜0.05);One month after surgery,there was a significant decrease in CYFRA21-1,SCC-Ag,and CA199 in both groups(P＜0.05),and in the observation group,the data of CYFRA21-1,SCC-Ag,and CA199 were(2.59±0.37)μg/L,(45.62±6.18)pg/L and(59.37±6.12)U/ml,respectively,which were lower than those in the control group[(3.12±0.43)μg/L,(60.27±7.35)pig/L,(63.28±6.49)U/ml](P＜0.05);One month after surgery,there was a significant decrease in VC,FVC,and FEV1 in both groups(P＜0.05).However,the VC,FVC,and FEV1 in the observation group were(67.21±8.69)％,(70.33±9.41)％,and(72.88±10.12)％,respectively,which were higher than those in the control group[(54.35±8.27)％,(61.65±8.79)％,(65.37±9.24)％](P＜0.05).There was no significant difference in the incidence of complications between the two groups(P＞0.05).Conclusion Both approaches can effectively treat esophageal cancer.Among them,the right chest approach can significantly improve the effect of lymph node dissection,inhibit inflammatory reactions,reduce tumor marker levels,and have less impact on lung function,without significantly increasing the risk of complications.However,the surgical time,bleeding volume,and postoperative recovery time are relatively long.Therefore,a suitable approach should be selected in clinical practice based on the patient's actual situation.
