OBJECTIVE To investigate the mechanism of pachymic acid on renal injury in pregnancy induced hypertension （PIH） rats by regulating the silent information regulator transcript 1/peroxisome proliferator-activated receptor γ coactivator-1α （Sirt1/PGC-1α） pathway. METHODS Pregnant SD rats were prepared by co-caging and PIH model was induced using N-nitro-L- arginine methyl ester （L-NAME） method. PIH rats were randomly divided into model group， L-pachymic acid （low-dose pachymic acid， 10 mg/kg） group， H-pachymic acid （high-dose pachymic acid， 20 mg/kg） group， and H-pachymic acid+EX527 （20 mg/kg pachymic acid+10 mg/kg EX527） group， with 6 rats in each group. Another 6 normal pregnant rats were selected as blank group. Each group was given relevant medicine or solvent intragastrically or intraperitoneally daily， once a day， for 28 consecutive days. After the last administration， 24 h urinary protein and tail artery systolic blood pressure （SBP） were measured in pregnant rats from each group， along with the levels of serum creatinine （Scr）， blood urea nitrogen （BUN），uric acid （UA）， and cystatin C （Cys-C）. The contents of superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione peroxidase （GSH-Px）， and 8-hydroxy-2′-deoxyguanosine （8-OHdG） in renal tissue， as well as the mRNA and protein expression levels of Sirt1 and PGC-1α， were also determined. Meanwhile， renal histopathological changes in rats from each group were evaluated using hematoxylin-eosin （HE） staining and periodic acid-Schiff （PAS） staining. RESULTS Compared with model group， L-pachymic acid group and H-pachymic acid group exhibited significant decreases in 24 h urine protein quantification， tail artery SBP， Scr， BUN， UA， Cys-C levels， glomerulosclerosis index score of renal tissue， renal tubular injury score， the percentage of PAS positive area， MDA and 8-OHdG （P＜0.05）. Conversely， the contents of SOD and GSH-Px， along with the mRNA and protein expression levels of Sirt1 and PGC-1α， were significantly increased （P＜0.05）. Moreover， these improvements were more pronounced in H-pachymic acid group （P＜0.05）. Compared with H-pachymic acid group， the aforementioned indicators in pregnant rats from the H-pachymic acid+EX527 group showed significant reversal （P＜0.05）. CONCLUSIONS Pachymic acid significantly ameliorates renal injury induced by PIH in rats， potentially through activation of the Sirt1/PGC-1α pathway.

Objective To investigate the current status of family resilience of children with cancer and analyze its influencing factors,to provide a basis for medical staff to formulate intervention plans.Methods Using a convenient sampling method,children with cancer who were hospitalized in 2 tertiary hospitals in Henan Province from January to April 2024 were selected for the survey.A general information questionnaire,family resilience assessment scale,quality of life family version,ZBI caregiver burden interview,and social support rating scale were used to understand the current status of family resilience of children with cancer and to explore the related influencing factors by univariate analysis and multiple stepwise linear regression analysis.Results A total of 280 questionnaires were distributed and 265 valid questionnaires were recovered,with a valid questionnaire recovery rate of 94.64％.The total score of family resilience for primary caregivers of children with cancer was(185.63±30.66).The multiple stepwise linear regression analysis results showed that the children's self-care ability,caregiver's work status,family care burden,and social support level were the influencing factors for family resilience of children with cancer(P＜0.05),and the explanatory variance was 51.3％.Conclusion The family resilience of children with cancer is at a medium level.The worse the children's self-care ability and the heavier the family care burden,the worse the family resilience;the caregiver's work status and good social support are helpful for the family resilience of children with cancer.Healthcare workers should develop intervention programs to address these factors to enhance the family resilience of children with cancer.

OBJECTIVE To explore the changes of serum mitochondrial ubiquitin ligase(MITOL),β-endorphin(β-EP)and chemokine 10(CXCL10)in the patients with herpes zoster(HZ)virus infection and analyze the predic-tive values.METHODS A total of 137 patients with HZ virus infection who were treated in Jinhua Fifth Hospital from Jan.2022 to Jan.2024 were assigned as the infection group,meanwhile,100 healthy people who received physical examination were chosen as the healthy group.The clinical data were compared between the two groups,the levels of serum MITOL,β-EP and CXCL10 were detected for the two groups of participants.The changes of the above indexes were observed and compared.The values of serum MITOL,β-EP and CXCL10 in prediction of HZ virus infection were analyzed by means of receiver operating characteristic(ROC)curves.RESULTS There were significant differences in the levels of serum MITOL,β-EP and CXCL10 between the infection group and the healthy group(P＜0.05).As the serum MITOL,β-EP and CXCL10 were used for prediction of HZ virus infec-tion,the area under the curve(AUC)of the CXCL10 was the highest 0.932,with the sensitivity 91.24％,the specificity 81.00％;the AUC of the joint detection of the three indexes was 0.882,with the specificity 99.00％,the sensitivity 77.37％(P＜0.05).CONCLUSIONS The patients with HZ virus infection show the decline of MI-TOL and β-EP levels and the rise of CXCL10 level.The three indexes have high values in prediction of HZ virus infection,with the CXCL10 showing the best prediction efficiency.The indexes can be used for prediction of illness condition of the patients with HZ virus infection.

Objective To investigate the effect of Scutellarin(Scu)regulating miR-26a-3p/Survivin molecular axis on myocardial ischemia/reperfusion injury(MIRI)in rats and its mechanism.Methods Fifty SD rats were randomly divided into sham group,model group,scutellarin group(Scu),miR-26a-3p agomir group(agomir)and scutellarin+miR-26a-3p agomir group(Scu+agomir)with 10 rats in each group.The animal model of MIRI was established by ligating the anterior descending coronary artery.The rats in each group were given 20 mg/kg Scu or 10 nmol agomir before and during operation,respectively,and the rats in sham group and model group were given the same amount of solvent.At 48 h after operation,the cardiac function of rats was examined by echocardiography.The pathological changes of myocardial tissue were detected by HE staining.The levels of myocardial injury markers creatine kinase isoenzyme MB(CK-MB),lactate dehydrogenase(LDH)and cardiac troponin I(cTnI)in serum and the contents of oxidative markers Malondialdehyde(MDA),superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)in myocardial tissue were detected by biochemical kit.The apoptosis of rat cardiomyocytes was detected by TUNEL staining.The mRNA expression levels of miR-26a-3p and Survivin in rat myocardium were detected by qRT-PCR.Expression levels of Survivin,cyclin-dependent kinase inhibitor(p21)and cleaved-caspase 3 were detected by Western blot.Results Compared with sham group,the pathological damage of myocardial tissue in the model group was serious,the levels of cardiac function LVEDP and serum CK-MB,LDH and cTnI significantly increased(P<0.01),and the levels of LVESP,LVEF and LVFS significantly decreased(P<0.01).The apoptosis level and MDA level of myocardial tissue significantly increased(P<0.01),while the SOD and GSH-Px levels significantly decreased(P<0.01).Meanwhile,the expression levels of miR-26a-3p and cleaved-caspase 3 protein significantly increased(P<0.01),the p21 protein and Survivin mRNA and protein expression levels significantly decreased(P<0.01).Compared with model group,the pathological injury of myocardium in Scu group was significantly improved,the levels of cardiac function LVEDP and serum CK-MB,LDH and cTnI significantly decreased(P<0.01),and the levels of LVESP,LVEF and LVFS significantly increased(P<0.01).The apoptosis level and MDA level of myocardial tissue significantly decreased(P<0.01),while the SOD and GSH-Px levels significantly increased(P<0.01).Meanwhile,the expression levels of miR-26a-3p and cleaved-caspase 3 protein significantly decreased(P<0.01),the p21 protein and Survivin mRNA and protein expression levels significantly increased(P<0.01).However,intervention with miR-26a-3p agomir could significantly reverse the improvement effect of Scu on MIRI in rats.Conclusion Scu can improve cardiac function and myocardial injury and inhibit myocardial cell apoptosis in MIRI rats,and its mechanism may be related to the regulation of miR-26a-3p/Survivin molecular axis.

Objective:To develop a Pain Management Nursing Competency Evaluation Index System for surgical nurses, providing a framework for assessing their pain management competency and guiding in-service training programs.Methods:From December 2023 to July 2024, a research team employed literature analysis, semi-structured interviews, expert consultations, and the analytic hierarchy process (AHP) to determine the content and weight of the competency evaluation index system. A cross-sectional survey was subsequently conducted using convenience sampling on 788 surgical nurses to test the internal consistency, test-retest reliability, and content validity of the index system.Results:The response rates for the two rounds of expert consultations were both 100% (46/46), with an expert authority coefficient of 0.921; the Kendall′s coefficients of expert opinions for the primary indicators were 0.106 and 0.245, respectively. The final index system included seven primary indicators (routine pain assessment, assessment and management of active and unexpected pain, pharmacological pain management, patient-controlled analgesia nursing, non-pharmacological pain management, pain related education for patients and their families, and professional development), 23 secondary indicators, and 78 tertiary indicators. The overall Cronbach α was 0.991, the test-retest reliability was 0.493, the item-level content validity index ranged from 0.96 to 1.00, and the scale-level content validity index was 0.98.Conclusions:The pain management nursing competency evaluation index system for surgical nurses is scientifically valid, reliable, and practical. It offers a solid foundation for evaluating the pain management competencies of surgical nurses and designing targeted in-service training programs.

Objective:To explore the effect of inspiratory muscle training(IMT)on respiratory function,psychological well-being,and sleep in patients recovered from corona virus disease 2019(COVID-19)infection.Method:Seventy-six adults who had recovered from COVID-19 between February and June 2023 at the depart-ment of rehabilitation medicine of the fourth medical center of the PLA general hospital,with a massive inspi-ratory pressure(MIP)of less than 70%were selected for this study.The participants were randomly divided into the control group(n=38)and the experimental group(n=38).The control group received conventional re-habilitation training,while the experimental group underwent an additional 4-week IMT program on top of con-ventional rehabilitation.Respiratory function including maximum massive inspiratory pressure(MIP),forced expi-ratory vital capacity(FVC),forced expiratory volume in the first second(FEV1),forced expiratory volume/forced vital capacity in the first second(FEV1/FVC),and peak expiratory flow rate(PEF),were measured be-fore and after the 4-week intervention.Psychological status and sleep quality were assessed using the Hamilton depression scale(HAMD),the Hamilton anxiety scale(HAMA)and Pittsburgh sleep quality index(PSQI).Result:After 4 weeks of intervention,the MIP,FVC,FEV1,FEV1/FVC,HAMD,HAMA,and PSQI im-proved in both control and experimental group compared with pre-intervention.The MIP,PEF,and PSQI in the experimental group were significantly better than pre-intervention(P<0.05);the control group showed sig-nificant improvement in MIP,FVC,FEV1,HAMA,and PSQI compared to pre-intervention(P<0.05).After 4 weeks of intervention,the MIP and PEF in the experimental group were significantly better than those in the control group(P<0.05);there was no significant difference in FVC,FEV1,FEV1/FVC,HAMD,HAMA,and PSQI between the two groups(P>0.05).Conclusion:IMT can effectively improve the respiratory function,physical and mental health of patients recov-ered from COVID-19,making it an effective rehabilitation strategy for post-COVID-19 recovery.

OBJECTIVE: To investigate the current status of early pain and agitation management in critically ill patients in Guizhou Province. METHODS: A retrospective study was performed using data collected from a quality control activity conducted between April and June 2021 in non-provincial public hospitals with general intensive care unit (ICU) in Guizhou Province. Hospital-level data included hospital name and grade, ICU staffing, and number of ICU beds. Patient-level data included characteristics of patients treated in the general ICU on the day of the survey (e.g., age, sex, primary diagnosis), as well as pain and agitation assessments and the types of analgesic and sedative medications administered within 24 hours of ICU admission. RESULTS: A total of 947 critically ill ICU patients from 145 hospitals were included, among which 104 were secondary-level hospitals and 41 were tertiary-level hospitals. Within 24 hours of ICU admission, 312 (32.9%) critically ill patients received pain assessments, and 277 (29.3%) received agitation assessments. Among the pain assessment tools, the critical care pain observation tool (CPOT) was used in 44.2% (138/312) of critically ill ICU patients, with a significantly higher usage rate in tertiary hospitals compared to secondary hospitals [52.3% (69/132) vs. 38.3% (69/180), P < 0.05]. The Richmond agitation-sedation scale (RASS) was used in 93.8% (260/277) of critically ill ICU patients for agitation assessment, with no significant difference between hospital levels. Among the 947 critically ill patients, 592 (62.5%) received intravenous analgesics within 24 hours, with remifentanil being the most commonly used [42.9% (254/592)]; 510 (53.9%) received intravenous sedatives, with midazolam being the most frequently used [60.8% (310/510)]. Mechanical ventilation data were available for 932 critically ill patients, of whom 579 (62.1%) received mechanical ventilation and 353 (37.9%) did not. Compared with non-ventilated patients, ventilated patients had significantly higher rates of analgesic and sedative use [analgesics: 77.9% (451/579) vs. 38.8% (137/353); sedatives: 71.8% (416/579) vs. 25.8% (91/353); both P < 0.05]. In terms of analgesic selection, ventilated patients were more likely to receive strong opioids than non-ventilated patients [85.8% (95/137) vs. 69.3% (387/451), P < 0.05]. For sedatives, ventilated patients preferred midazolam [66.6% (277/416)], whereas non-ventilated patients more often received dexmedetomidine [45.1 (41/91)]. Blood pressure within 24 hours of ICU admission were available for 822 critically ill patients, of whom 245 (29.8%) had hypotension and 577 (70.2%) did not. Compared with non-hypotensive patients, hypotensive patients had significantly higher rates of analgesic and sedative use [analgesics: 74.7% (183/245) vs. 59.8% (345/577); sedatives: 65.7% (161/245) vs. 51.3% (296/577); both P < 0.05], but there was no significant difference in the choice of analgesic or sedative agents between the two groups. CONCLUSIONS The proportion of critically ill ICU patients in Guizhou Province who received standardized pain and agitation assessments was relatively low. The most commonly used assessment tools were CPOT and RASS, while remifentanil and midazolam were the most frequently used analgesic and sedative agents, respectively. Secondary-level hospitals had a lower rate of using standardized pain assessment tools compared to tertiary-level hospitals. Mechanical ventilation and hypotension were associated with the use of analgesic and sedative medications.
