Objective:To compare the effects of regional nerve block and general anaesthesia in elderly patients undergoing traumatic lower limb fracture surgery.Methods:A total of 100 patients over 60 years old with traumatic lower extremity fracture who received surgical treatment in Yan′an People′s Hospital from October 2021 to October 2023 were prospectively selected as the study objects and divided into two groups with 50 cases in each group by random number table method. The control group was given general anesthesia, and the observation group was given regional nerve block. Both groups were given patient controlled intravenous analgesia (PCIA) after surgery. Perioperative hemodynamic indexes, surgical conditions, postoperative visual analogue scale (VAS) score, analgesia recovery rate and stress response indexes before and after surgery were compared between the two groups, and the incidence of complications were compared between the two groups.Results:The mean arterial pressure (MAP) and heart rate (HR) at the beginning of 5 min (T 1) and at the end of the operation (T 2) were decreased compared with the time point before entry (T 0), and there were no statistical differences of MAP, HR at 30 min after the operation (T 3) between the two groups ( P>0.05). The MAP and HR at T 1 and T 2 time points in the observation group were higher than those in the control group, there were statistical differences ( P<0.05). The amount of infusion in the observation group was lower than that in the control group: (443.63 ± 31.47) ml vs. (645.25 ± 45.85) ml, there was statistical difference ( P<0.01). There were no statistical differences in operation time and postoperative hospital stay between the two groups ( P>0.05). The VAS scores in the observation group at 6, 12, 24 and 48 h after surgery were lower than those in the control group: (3.21 ± 0.61) scores vs. (3.89 ± 0.74) scores, (3.45 ± 0.67) scores vs. (4.12 ± 0.78) scores, (2.57 ± 0.47) scores vs. (3.04 ± 0.64) scores, (1.96 ± 0.34) scores vs. (2.34 ± 0.45) scores; and the analgesic relief rate was lower than that in the control group: 8.00%(4/50) vs. 24.00%(12/50), there were statistical differences ( P<0.05). The levels of cortisol (Cor), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and β-endorpeptide (β-EP) at 24 h postoperative in the observation group were lower than those in the control group: (134.74 ± 28.94) ng/L vs. (158.52 ± 35.63) ng/L, (102.53 ± 15.41) μg/L vs. (128.95 ± 18.74) μg/L, (47.54 ± 5.72) ng/L vs. (59.74 ± 6.98) ng/L, (38.74 ± 4.17) μg/L vs. (45.75 ± 5.12) μg/L, there were statistical differences ( P<0.05). There was no statistical difference in complication rate between the two groups ( P>0.05). Conclusions:Regional nerve block can stabilize the intraoperative hemodynamics, reduce the stress response of the body and have a good analgesic effect in the operation of lower extremity fracture in the elderly.

Objective To organize and summarize the medication rules of GU Nai-fang in treating skin diseases through real-world data.Methods We collected traditional Chinese medicine prescriptions for GU Nai-fang's treatment of skin diseases from the outpatient medical record system of Shanghai Traditional Chinese Medicine Hospital to establish a database.Statistical analysis of disease types,performance,and efficacy was conducted,and association rules and systematic clustering analysis were performed using SPSS Modeler 18.0 and SPSS 26.0 software,respectively.Results A total of 5 020 patients were included,and 5 020 prescriptions were collected,involving 241 traditional Chinese medicines with a total frequency of 85 758 uses.The frequency of using heat clearing drugs,deficiency tonifying drugs,blood activating and stasis removing drugs,surface clearing drugs,and wind and dampness dispelling drugs was relatively high;most drugs tended to be cold and warm,mainly targeting the heart,lungs,and colon meridians.The top 15 Chinese medicines with the highest frequency of use were Smilacis Glabrae Rhixoma,Cortex Moutan,Radix Paeoniae Rubra,Rehmanniae Radix,Scutellariae Radix,Cynanchi Paniculati Radix et Rhizoma,Schisandrae Chinensis Fructus,Violsse Herba,Mume Fructus,Herba Pyrolae,Hedyotis Diffusae Herba,Lonicerae Japonicae Flos,Cicadae Periostracum,Bombyx Batryticatus,Radix Salviae.Association rule analysis obtained 15 high-frequency combinations of 2 traditional Chinese medicines and 3 traditional Chinese medicines.Cluster analysis resulted in 7 clustered prescriptions.Conclusion GU Nai-fang commonly used heat clearing drugs,deficiency tonifying drugs,blood activating and stasis removing drugs,surface resolving drugs,and wind and dampness dispelling drugs in the treatment of skin diseases,and Smilacis Glabrae Rhixoma,Cortex Moutan,Radix Paeoniae Rubra,Rehmanniae Radix,and Scutellariae Radix were the most frequently used drugs.

Objective To explore the correlation between the proximal angle of carotid atherosclerotic plaques and neovascularization scores,and their clinical application value in predicting recurrent cerebral infarction.Methods A total of 88 patients who underwent carotid plaque ultrasound examination in our hospital were selected.According to CT/MRI results,patients were divided into the non-cerebral infarction group(45 cases)and the cerebral infarction group(43 cases).Conventional ultrasound examination was performed followed by contrast-enhanced ultrasound.Plaque length,thickness and proximal angle were measured,and the neovascularization score of the proximal end was evaluated using contrast-enhanced ultrasound,and the results were compared and analyzed.Results In the cerebral infarction group,plaque thickness,proximal angle,and neovascularization score were significantly higher than those in the non-cerebral infarction group(P＜0.05),while there was no significant difference in plaque length.The proportion of plaques with a proximal neovascularization score of 2 or 3 was higher in the cerebral infarction group than those of the non-cerebral infarction group(79.1%vs.24.4%,P＜0.01).A positive correlation was found between the proximal angle and neovascularization score in all patients(rs=0.374,P＜0.01).There was no significant difference between the area under the ROC curve for neovascularization score in predicting recurrent cerebral infarction and the proximal angle(P＞0.05).The optimal cutoff value of the proximal angle was 18.8,and the sensitivity and the specificity for predicting recurrent cerebral infarction were 93.0%and 62.2%.In the cerebral infarction group,seven patients(16.3%)had recurrent infarction within one year,and these patients had higher proximal neovascularization scores,with angles greater than 18.8°.Conclusion There is a strong correlation between proximal angle of carotid plaques and neovascularization score,which has a positive predictive role in the recurrence of cerebral infarction,providing a reliable auxiliary diagnostic basis for clinical practice.

Objective To explore the evidence for Traditional Chinese Medicine(TCM)in the treatment of premature ovarian insufficiency(POI)based on evidence map and re-evaluation of systematic reviews.Methods CNKI,WanFang Data,VIP,SinoMed,PubMed,Embase,Cochrane Library and Web of Science database were electronically searched to collect systematic reviews(SR)/Meta-analysis on the treatment of POI with TCM from the inception to March 31,2025.The reporting quality,methodological quality,and evidence quality of the included studies were evaluated using the PRISMA 2020 Statement,AMSTAR 2 Checklist,and GRADE system,respectively.The interventions,number of studies,and evidence grades were comprehensively displayed using evidence map.Results A total of 15 SR/Meta-analysis were included,comprising 9 Chinese articles and 6 English articles.The PRISMA 2020 checklist evaluation revealed that 8 articles had certain deficiencies in reporting,while 7 articles demonstrated relatively complete reporting.Based on the AMSTAR 2 checklist,5 articles were rated as high-level and 10 as very low-level.A total of 10 primary outcome indicators were involved,reported 133 times.When classified using the GRADE system,there were 20 pieces of moderate-quality evidence,58 pieces of low-quality evidence,and 55 pieces of very low-quality evidence.The evidence map showed that TCM alone or in combination with hormone therapy could effectively treat POI,reduce follicle-stimulating hormone and luteinizing hormone levels,increase estradiol levels,and improve clinical manifestations and TCM syndrome manifestations.Conclusion TCM has certain advantages in the treatment of POI,enhancing the overall treatment effect,alleviating clinical symptoms of low estrogen,and regulating sex hormone levels to some extent.However,there are deficiencies in methodological quality and reporting quality,and the level of evidence is not high.Therefore,the findings should be used with caution in clinical practice.

[Objective]To clarify the associations between plasma fibrinogen(Fbg)and volumetric bone mineral density(vBMD)as well as osteoporosis measured by quantitative computed tomography(QCT),and to explore the role of plasma Fbg in early screening and diagnosis of osteoporosis.[Methods]Patients with hypertension who were hospitalized in the Department of Endocrinology of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2018 to June 2022 and underwent QCT examinations were included for cross-sectional analysis.The study analyzed the correlation between plasma Fbg and osteoporosis in patients.The diagnostic efficacy of plasma Fbg for osteoporosis was evaluated by the area under the receiver operating characteristic(ROC)curve(AUC).[Results]Totally 441 subjects were included in the analysis,with an average age of 46.0±14.5 years and a prevalence of osteoporosis of 6.4%(28/441).As the level of plasma fibrinogen increased,the incidence of osteoporosis significantly increased(P<0.000 1)while the average bone mineral density of L1 and L2 were significantly decreased(P<0.05).Compared with the first quartile of plasma Fbg(1.99g/L-2.37g/L),the risk of osteoporosis in the fourth quartile of plasma Fbg(3.67g/L-4.46g/L)increased by 8.85 times after adjusting for related confounding factors.[Conclusion]This study found a negative correlation between plasma fibrinogen levels and bone density in patients with hypertension.Plasma fibrinogen levels may serve as a potential screening indicator for osteoporosis,aiding in early diagnosis and therapeutic monitoring.This discovery offers a new perspective for the study of bone metabolic diseases and warrants further investigation.

Autoimmune oophoritis is a rare cause of primary ovarian insufficiency(POI), and some patients may also have concurrent adrenal insufficiency. This condition significantly impairs reproductive function and is often difficult to distinguish from common causes of POI, leading to missed or incorrect diagnoses. This paper reports a case of autoimmune oophoritis treated in our department and provides an updated summary of recent advances in the understanding of this condition, with the aim of raising clinical awareness and improving diagnostic accuracy among healthcare professionals.

Objective:To investigate the predictive value of color Doppler ultrasound combined with electrocardio-gram for right heart dys function in patients with pulmonary heart disease(PHD).Methods:A total of 100 PHD patients admitted in Dongcheng Branch of First Affiliated Hospital of Anhui Medical University between January 2020 and December 2023 were retrospectively analyzed.According to results of 6min walking test(6MWT),pa-tients were divided into good right heart function group(n=64,≥350m)and right heart dysfunction group(n=36,＜350m).The indexes of cardiac color ultrasound[isovolumic relaxation time(IVRT),isovolumetric contraction time(IVCT)and right ventricular Tei index],ECG[24h mean R-R interval standard deviation(SDNN),normal R-R interval standard deviation per 5min(SDANN)and the ratio of low frequency components to high frequency components(LF/HF)]were compared between two groups.Receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic value of color Doppler ultrasound,ECG and their combination for right heart dys-function in PHD patients.Spearman correlation coefficient was used to analyze the association of color Doppler ul-trasound,ECG and their combination with right heart dysfunction in PHD patients.Results:Compared with those in good right heart function group,patients in right heart dysfunction group had significant higher IVRT[(120.64±14.08)ms vs.(97.87±10.93)ms],IVCT[(84.28±12.33)ms vs.(71.92±10.61)ms]and Tei index[(0.85±0.11)vs.(0.63±0.07)](P＜0.001 all),and significant lower SDNN[(75.52±12.58)ms vs.(85.58±11.75)ms],SDANN[(63.86±10.92)ms vs.(76.75±11.71)ms]and LF/HF[(1.33±0.19)vs.(1.84±0.27)](P＜0.001 all).ROC curve indicated that the AUC of color Doppler ultrasound combined ECG in diagnosing right heart dysfunction in PHD patients was 0.911(95％CI 0.838～0.959),which was significantly higher than those of color Doppler ultrasound[0.775(95％CI 0.681～0.853),Z=2.404,P=0.016]and ECG[0.688(95％CI 0.588～0.777),Z=3.968,P=0.001]alone.Spearman correlation analysis indicated that there was a significant positive correlation of color Doppler ultrasound(r=0.547),ECG(r=0.375)and their combination(r=0.810)with right heart dysfunction in PHD patients(P＜0.001 all),and the correlation between combined detection and right heart dysfunction in PHD patients was significantly higher.Conclusion:Color Doppler ultrasound combined with ECG possesses high diagnostic performance for right heart dysfunction in PHD patients.

Objective:To explore the effects of perceived stress on ego depletion of college students, as well as the mediating role of emotional eating and the moderating role of peer relationship.Methods:A cross-sectional survey of 1 088 college students was conducted using the perceived stress scale, the Dutch eating behavior questionnaire, the self-control resource depletion scale, and the peer relationship measurement from December 2023 to April 2024.PROCESS Macro program in SPSS 25.0 software was used to test the mediating effect of emotional eating and the moderating effect of peer relationship.Results:(1)The score of perceived stress, emotional eating, peer relationship and ego depletion were 39.26±8.35, 39.19±12.15, 2.00(1.00), and 18.19±7.15, respectively.(2)Perceived stress was positively correlated with emotional eating, ego depletion, and peer relationship( r=0.36, 0.61, 0.25, all P<0.01). Emotional eating was positively correlated with ego depletion and peer relationship( r=0.40, 0.19, both P<0.01). And ego depletion was positively correlated with peer relationship( r=0.23, P<0.01).(3)Emotional eating played a partial mediating role in the effect of perceived stress on ego depletion( β=0.077, 95% CI=0.053-0.104), and the mediating effect accounted for 12.38%(0.077/0.622) of the total effect.(4)Peer relationship played a moderating role between perceived stress and emotional eating. Under low peer relationship, perceived stress had a significant positive predictive effect on emotional eating( βsimple=0.46, P<0.01), and under high peer relationship, the predictive effect of perceived stress on emotional eating was significantly weaker( βsimple=0.26, P<0.01). Conclusions:Perceived stress not only directly affects ego depletion, but also indirectly affects ego depletion through emotional eating in college students.High levels of peer relationship can weaken the impact of perceived stress and high emotional eating on ego depletion.
