Objective:To observe the effects of ear acupressure combined with acupoint application on serum inflammatory factors,pain and psychological status of children with limb fractures.Methods:By using random number table method,60 children with limb fracture who were admitted to Qiantang Campus of Zhejiang Provincial Traditional Chinese Medicine Hospital from February 2022 to August 2024 were divided into control group(received conventional treatment combined with acupoint application)and experimental group(combined with ear acupressure based on the control group),with 30 cases in each group.Pain and swelling degree of the affected limb,anxiety and depression[Screening Checklist for Childhood Anxiety Disorders(SCARED),Depression self-rating scale for children(DSRSC)],inflammatory factors[High sensitivity C-reactive protein(hs-CRP),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),interleukin-1(IL-1)]and family satisfaction rate were compared between the two groups.Results:The scores of visual analogue scale(VAS),SCARED and DSRSC in the experimental group were lower than those in the control group at 1 week and 4 weeks after treatment(P＜0.05).Swelling degree of the affected limb in the experimental group was better than that in the control group at 4 weeks after treatment(P＜0.05).hs-CRP,IL-1,IL-6 and TNF-α in the experimental group were lower than those in the control group at 4 weeks after treatment(P＜0.05).The family satisfaction rate in the experimental group was higher than that in the control group(P＜0.05).Conclusion:Ear acupressure combined with acupoint application therapy for children with limb fractures can significantly alleviate postoperative pain,promote swelling reduction,effectively reduce inflammation,and improve anxiety and depression,with high treatment satisfaction.

AIM:To observe the effect of opioid-free anesthesia with esketamine on delirium after hip replacement surgery in elderly patients.METH-ODS:One hundred and fourteen elderly patients who underwent hip replacement were randomly di-vided into two groups:opioid-free anesthesia(OFA)group and opioid anesthesia(OA)group(n=57).During anesthesia induction and maintenance,es-ketamine was administered in OFA group,and that fentanyl and remifentanil were administered in OA group.Delirium was mainly recorded within 3 days after the surgeries,and the patients'delirium sta-tus was evaluated using the Chinese Revised Deliri-um Diagnostic Scale(CAM-CR).RESULTS:The pa-tients in OFA group had lower CAM-CR scores and delirium incidence compared to those in the OA group at 2 days after surgery.CONCLUSION:Opioid-free anesthesia based on esketamine can effective-ly reduce delirium after hip replacement in elderly patients.

Objective:To describe the body mass index (BMI) level and long-term trends of Chinese older adults aged 65 and above.Methods:Older adults aged 65 and above from six waves (2002-2018) of the China Longitudinal Healthy Longevity Survey were selected as the study population. Multiple cross-sectional design with six survey waves conducted in 2002, 2005, 2008, 2011, 2014, and 2018 was adopted, enrolling 15 647, 15 358, 15 622, 9 166, 6 302, and 12 417 participants, respectively. Additionally, a total of 13, 755 participants were included in the cohort study design. Relevant information was collected through questionnaires and physical examinations. The χ2 trend test was used to compare the changes in the rates of underweight and overweight/obesity over the years, and the linear mixed-e?ects model (LMM) was used to fit trajectory curves of BMI changes with advancing age in older adults. Results:The baseline ages of the participants included in 2002, 2005, 2008, 2011, 2014, and 2018 were (85.16±11.26), (84.23±11.83), (84.99±12.16), (81.10±11.86), (78.89±11.30), and (83.08±12.42) years, respectively, with a relatively high proportion of females and rural residents. In the cohort study, the 13 755 participants had a median ( Q1, Q3) follow-up time of 6.5 (5.2, 10.0) years, with a cumulative follow-up duration of 109 041 person-years. In each wave, males had higher BMI than females, urban residents had higher BMI than rural residents, and BMI gradually decreased with increasing age (all P<0.001). The mean BMI of older adults in China increased from (19.37±3.80) kg/m2 in 2002 to (22.04±4.01) kg/m2 in 2018 ( P<0.001). Across all survey years, the prevalence of underweight was consistently higher in women than in men and in rural areas than in urban areas, with an upward trend as age increased (all P<0.001). In 2018, the underweight rates in the 65-79, 80-89, 90-99, and ≥100-year-old age groups were 8.0%, 16.7%, 26.2%, and 35.5%, respectively. Meanwhile, the prevalence of overweight/obesity was higher in men than in women and in urban areas than in rural areas, showing a declining trend with advancing age (all P<0.001). The prevalence of underweight among the older adults decreased significantly from 45.2% in 2002 to 18.9% in 2018 ( P<0.001), while the prevalence of overweight/obesity increased from 11.0% in 1998 to 29.6% in 2018 ( P<0.001). The trajectory curves fitted by the LMM model showed that individuals born in later decades had higher BMI levels at the same age compared to earlier cohorts. Conclusion:From 2002 to 2018, the BMI level among Chinese older adults showed an increasing trend. The prevalence of underweight showed a declining trend, while the rates of obesity and overweight increased. However, the underweight rate remained notably high among the oldest old.

Objective:To investigate the differences between high-frequency ultrasound-guided manual detorsion combined with surgery(MD+S)and surgery alone in the treatment of testicular torsion,and to provide some new evidence for the timely diagno-sis and treatment of the disease.Methods:We retrospectively analyzed the clinical data on 134 cases of unilateral testicular torsion within 48 hours treated in our hospital by MD+S or by surgery alone from January 2015 to May 2022.We statistically analyzed the age distribution,and duration and degrees of testicular torsion,followed by comparison between the two groups.Results:In the 134 ca-ses,the median age of onset was 15(13-19)years old,the median onset-to-visit time was 15(8-25)hours,and the median de-gree of torsion was 360°(180°-1080°).Of the total number of patients,21 underwent testicular excision and the other 113 were treated with the testis preserved,with no statistically significant difference in age distribution between the two groups(P＞0.05),and a higher rate of testis resection in those with longer duration and greater angle of torsion(P＜0.05).Totally,33 of the patients were assigned to the MD+S group and 101 to the surgery alone group.According to the actual clinical conditions and excluding those with torsion time longer than 24 hours and torsion angle greater than 720 °,28 of the patients underwent ultrasound-guided MD+S(with 1 case of testis resection,3.6％),and 68 received surgery alone(with 7 cases of testis resection,10.3％).The rate of testis resection was higher in the surgery alone than that in the MD+S group,but with no statistically significant difference between the two groups(P＞0.05),which was considered to be related to the small sample size in this study.Conclusion:The popularization of testicular torsion knowledge can shorten the onset-to-visit time,and reasonable manual detorsion before emergency surgery can reduce the rate of testis resection.

OBJECTIVE: To explore and quantify the association of hot night exposure during the sperm development period (0-90 lag days) with semen quality. METHODS: A total of 6,640 male sperm donors from 6 human sperm banks in China during 2014-2020 were recruited in this multicenter study. Two indices (i.e., hot night excess [HNE] and hot night duration [HND]) were used to estimate the heat intensity and duration during nighttime. Linear mixed models were used to examine the association between hot nights and semen quality parameters. RESULTS: The exposure-response relationship revealed that HNE and HND during 0-90 days before semen collection had a significantly inverse association with sperm motility. Specifically, a 1 °C increase in HNE was associated with decreased sperm progressive motility of 0.0090 (95% confidence interval [ CI]: -0.0147, -0.0033) and decreased total motility of 0.0094 (95% CI: -0.0160, -0.0029). HND was significantly associated with reduced sperm progressive motility and total motility of 0.0021 (95% CI: -0.0040, -0.0003) and 0.0023 (95% CI: -0.0043, -0.0002), respectively. Consistent results were observed at different temperature thresholds on hot nights. CONCLUSION Our findings highlight the need to mitigate nocturnal heat exposure during spermatogenesis to maintain optimal semen quality.

Objective:To explore the influence of environment temperature on the incidence of testicular torsion.Methods:We collected the clinical data on 172 cases of testicular torsion diagnosed in the Second Hospital of Hebei Medical University from De-cember 2013 to December 2020.According to the local environment temperature on the day of onset,we divided the patients into groups A(below 0℃),B(0-10℃),C(10-20℃)and D(above 20℃),and compared the incidence rates of testicular torsion among the four groups,followed by correlation analysis.Results:The incidence rate of testicular torsion was 12.8％(n=22)in group A,35.5％(n=61)in B,34.9％(n=60)in C and 16.9％(n=29)in D,the highest at 0-10℃ in group B,with sta-tistically significant difference among the four groups(x2=29.07,P＜0.001).Spearman correlation analysis indicated that the inci-dence of testicular torsion was negatively correlated with the environment temperature(r=-0.261,P＜0.01),with no statistically significant difference among different seasons(x2=5.349,P＞0.05),but higher in autumn and winter than in the other two sea-sons.Conclusion:The incidence of testicular torsion is negatively correlated with the environment temperature,elevated when the temperature decreases,but has no statistically significant difference among different seasons,though relatively higher in autumn and winter.

Tricuspid regurgitation(TR)is a common heart valve disease.According to the pathogenesis,TR can be divided into primary(organic)and secondary(functional)regurgitation,of which functional TR accounts for more than 90%.Patients with severe TR have poor prognosis and poor drug treatment,and surgery(valvuloplasty)is the main treatment.At present,transcatheter edge-to-edge tricuspid valve repair(T-TEER)has become an essential program of transcatheter treatment for TR,providing minimally invasive treatment for TR patients who cannot undergo surgery or are at high risk of surgery.T-TEER reduces the degree of regurgitation by clamping leaflets,and is currently in the early stage of research and development exploration and clinical validation,mainly for functional TR.T-TEER devices have also made significant progress(TriClip,PASCAL),and Chinese-made novel-designed T-TEER devices are also undergoing clinical trials(DragonFly-TTM,SQ-Kyrin-TTM,NeoBlazarTM).This paper reviews the current applications and research progress of T-TEER.
