BACKGROUND:The quadriceps strength of patients with osteoporosis and sarcopenia is significantly reduced,which can further reduce the function of the knee joint,affect the function of the lower limbs and even lead to a decrease in whole-body coordination.It is speculated that a reasonable quadriceps training program and personalized guidance are beneficial to the recovery of knee joint function in patients with osteoporosis and sarcopenia.OBJECTIVE:To observe the effect of short-term moderate-intensity resistance rehabilitation training on the mass and function of the quadriceps and knee joint function in patients with osteoporosis and sarcopenia.METHODS:Using the integrated physical examination and rehabilitation model,375 patients with osteoporosis and sarcopenia were screened at the Health Management Center of Shanghai Public Health Clinical Center.They underwent 12 weeks of combined/comprehensive exercise rehabilitation based on resistance exercise,including quadriceps resistance isotonic and isometric contraction training twice a week(3-5 sets each time,10-15 minutes per set)and aerobic exercise/balance exercise two or three times a week(30 minutes each time).Assessments and data collection were performed before rehabilitation training,12 weeks after rehabilitation training,and at follow-up 12 weeks after stopping rehabilitation training,mainly including knee joint range of motion and proprioception,quadriceps muscle strength,and cross-sectional area(magnetic resonance imaging results),pain,knee joint function(Hospital for Special Surgery score)and walking function("up-and-go"time and 6 m pace test results)as well as the patient's psychological status assessment.RESULTS AND CONCLUSION:All 375 patients completed 12 weeks of rehabilitation training and 12 weeks of follow-up without any adverse events.(1)Compared with before training,the patients' gait speed and knee range of motion increased significantly after 12 weeks of rehabilitation training(P＜0.01),the time of"stand-to-walk"decreased(P＜0.01),and the proprioception of the knee joint and the strength of the quadriceps femoris were significantly improved(P＜0.01);and at the follow-up visit 12 weeks after stopping training,the above indicators and functions of the patients were well maintained(P＞0.05).(2)Magnetic resonance imaging results showed that the effective cross-sectional area of the quadriceps femoris did not improve significantly after 12 weeks of rehabilitation training(P＞0.05);but the Hospital for Special Surgery score of knee joint function increased significantly(P＜0.01),and the visual analog pain scale score decreased significantly(P＜0.01),suggesting that this may be related to the improvement of quadriceps femoris quality by resistance rehabilitation training.(3)The results of the Hospital Anxiety and Depression Scale score showed that the anxiety and depression scores of the patients continued to decrease,both at 12 weeks of rehabilitation training and at 12 weeks after stopping training(P＜0.01).It is suggested that resistance rehabilitation training of the quadriceps can help patients with osteoporosis and sarcopenia to restore quadriceps muscle strength,increase range of motion,improve proprioception and joint stability,thereby enhancing knee joint function,reducing pain,improving depression and anxiety,and to a certain extent promoting the coordinated recovery of the musculoskeletal system.

Autism Spectrum Disorder （ASD） is a neurodevelopmental disorder with rapidly increasing global prevalence， characterized by core symptoms of social communication deficits and stereotyped repetitive behaviors. Although genetic predisposition， abnormal epigenetic regulation， perinatal environmental exposure， and nutritional-metabolic imbalances are recognized as major risk factors， the precise etiological mechanisms remain incompletely understood. Current clinical management primarily relies on behavioral interventions， with limited pharmacological options accompanied by adverse effects. Recent studies have demonstrated the unique therapeutic value of active components from Chinese herbal medicine in ASD intervention. This article reviews the mechanisms underlying various Chinese herbal active components in ASD treatment， including improvements in synaptic dysfunction， blood-brain barrier impairment， neurotransmitter regulation， cerebellar dysfunction， immune dysregulation and neuroinflammation， oxidative stress， programmed neuronal cell death， and lipid metabolism. These bioactive components exhibit multi-target and multi-pathway regulatory effects， providing novel therapeutic strategies and directions for ASD.

Objective To explore the effect of the preservation of infrapatellar fat pad on pain,incision healing and function recovery in patients with knee osteoarthritis after joint replacement.Methods The clinical data of 127 patients with knee osteoarthritis who underwent joint replacement in the hospital from June 2019 to September 2022 were retrospectively collected.According to the preservation of infrapatellar fat pad,the subjects were divided into a control group(removing infrapatellar fat pad,67 cases)and an observation group(preserving infrapatellar fat pad,60 cases).The changes in length of patellar tendon,pain,knee function and range of motion were analyzed.The occurrence of adverse reactions was statistically analyzed.Results At 12 months after surgery,the length of patellar tendon was reduced.The length of patellar tendon in observation group[(38.8±6.24)mm]was longer than that in control group[(36.2±6.71)mm](P＜0.05).Observation group of patellar tendon length rate is lower than the control group[(4.1±1.18)％vs(10.7±3.01)％],there was statistical significance between the two groups(P＜0.05).Pain in both groups was alleviated at 1 month,3 months,6 months and 12 months after surgery.The changes in observation group were greater than those in control group(P＜0.05).During follow-up,the incidence of adverse reactions in observation group(6.67％)was lower than that in control group(14.93％)(P＞0.05).The range of motion and function of knee joint were improved at 12 months after surgery,and the improvement in observation group was greater than that in control group(P＜0.05).Conclusion Preserving infrapatellar fat pad is more beneficial to relieving postoperative pain and restoring knee function in patients with knee osteoarthritis after joint replacement.Therefore,the intact infrapatellar fat pad should be preserved as possible in clinical practice.

Objective:To analyze the epidemiological characteristics and infection sources of cholera in China from 2005 to 2024.Methods:A total of 2 066 cholera cases were included in the study, which were obtained from the China Disease Control and Prevention Information System (CDPCIS) of China CDC. The information on cholera clusters was downloaded from the National Public Health Emergency Event Surveillance System (PHEESS) of China CDC. A total of 128 cholera clusters were included and analyzed in this study. The epidemiological characteristics and infection sources of cholera were analyzed. The Jointpoint model was applied to analyze the incidence trend, and annual percentage change (APC) was also quantified.Results:From 2005 to 2024, a total of 2 066 cholera cases were reported, with an average of 103 cases reported annually. Specifically, the incidence showed a marked downward trend from 2004 to 2015 ( APC=-26.78%, P=0.006). During 2015-2024, the disease remained at low endemic levels, with an average of 18 reported cases annually ( APC=-2.68%, P=0.807). Cholera peak season was from May to October. A total of 24 provinces reported cholera cases, which were mainly distributed in Zhejiang, Fujian, Beijing, Jiangsu, Anhui, Guangdong, and Hainan provinces, accounting for 78.03% of the total cases. Pathogen surveillance indicated an alternating prevalence of Vibrio cholerae serogroups O1 and O139 among laboratory-confirmed cases between 2005 and 2024. There was a disparity in the dominant serogroup of Vibrio cholerae by region. The results from 128 cholera clusters indicated that cholera outbreaks frequently occurred in rural banquets (64.84%), followed by regular restaurants (13.28%). Among these, 63 clusters (49.22%) with identified infection sources indicated that foodborne transmission (95.24%) was the primary mode of cholera transmission, which mainly through seafood and aquatic products, such as soft-shelled turtles, shrimp and shellfish. The characteristics of cholera clusters caused by Vibrio cholerae serogroups O1 and O139 showed statistically significant differences in scale, attack rate, place of residence, setting, and infection source ( P<0.05). Conclusion:Cholera incidence has remained consistently low since 2015 in China, mainly in sporadic cases. Rural gatherings (e.g., wedding banquets) are the main settings for cholera clusters. The main infection sources are predominantly caused by cross-contamination due to improper processing practices of aquatic products, such as soft-shelled turtles.

Objective To explore the characteristics and prognosis of follicular lymphoma(FL)with bulky disease under rituximab-based first-line treatment.Methods A retrospective analysis was conducted on 525 FL patients diagnosed between September 2009 and September 2021 who received rituximab as a first-line treat-ment[342 patients received rituximab combined with chemotherapy(R-chemo),183 patients received rituximab plus lenalidomide(R2)].The clinicopathologic characteristics,gene mutations,and prognosis of bulky FL patients were analyzed.Results Compared to non-bulky FL patients,bulky FL patients had a significantly higher proportion of lymph node≥5 sites,≥2 extranodal involvement,bone marrow involvement,elevated LDH,and a higher proportion in the high-risk group of FLIPI1 and FLIPI2.Gene sequencing revealed a significantly higher mutation rate of ZNF608 in bulky FL patients compared to non-bulky FL patients.In patients receiving R-chemo as the first-line treatment,there was no significant difference in progression-free survival(PFS)and overall survival(OS)between bulky and non-bulky FL patients.However,in patients treated with R2,the PFS and OS of bulky FL patients was significantly shorter.Conclusions Bulky FL patients compared to non-bulky FL patients have a significantly higher proportion of high-risk baseline characteristics.For bulky FL at diagnosis,chemo-free regimens require further exploration on the basis of R2.

Objective:To explore the impulsivity characteristics of patients with attention deficit hyperactivity disorder(ADHD)comorbid with borderline personality disorder(BPD)and the mediating role of emotion regula-tion strategies.Methods:A total of 96 patients with ADHD meeting the diagnostic criteria of the American Diagnos-tic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ)were enrolled,48 of whom had comorbid BPD.Impulsivity was assessed with the Barratt Impulse Scale(BIS)and the impulse control difficulty dimensions of Emotional Regulation Difficulty Scale(DERS).Emotion regulation strategies were evaluated with the Emotion Regulation Questionnaire(ERQ).Results:No significant differences were found between the ADHD with and with-out BPD group in cognitive impulsivity,motor impulsivity,or non-planning impulsivity as assessed with the BIS(Ps＞0.05).However,the ADHD with BPD group showed higher scores on the DERS impulse control difficulty subscale(P＜0.001)and less frequent use of cognitive reappraisal strategies(P＜0.001).Cognitive reappraisal partially mediated the relationship between ADHD with BPD and impulse control difficulties,with an effect size of 25.9％.Conclusion:ADHD patients comorbid with BPD exhibit heightened emotional impulsivity,which might be partially mediated by reduced use of cognitive reappraisal.

Objective:To explore the safety and efficacy of computed tomography (CT) guided percutaneous interstitial brachytherapy in the treatment of recurrent cervical cancer with isolated lesions in the radiated field.Methods:A retrospective analysis was conducted on the clinical data of 30 patients with recurrent cervical cancer with isolated lesions in the radiated field who underwent CT guided percutaneous interstitial implantation for close range radiation treatment at Zhengzhou University Affiliated Cancer Hospital from March 2023 to August 2024. Under local anesthesia, a needle was implanted into the recurrent tumor in the pelvic or abdominal wall of the patients percutaneously guided by CT. The target area was delineated to ensure full dose coverage. The prescribed dose for high-risk clinical target areas was 600 cGy/time, once a week, followed by close range radiotherapy. The number of implanted needles were recorded, and the target area, radiation dose, and other parameters were evaluated through dose volume parameter maps. The degree of lesion shrinkage and the occurrence of complications during and after treatment were observed.Results:30 patients underwent a total of 72 rounds of brachytherapy with implantation, with a technical success rate of 100% (72/72). 20 cases received 2 treatments, 8 cases received 3 treatments, and 2 cases received 4 treatments; 4 cases used 1needle, 20 cases used 2 needles, 4 cases used 3 needles, and 2 cases used 4 needles. The high-risk clinical target dose D 90 was (718.17±222.61) cGy. The average dose D 2cc of 2 cm 3 surrounding the bladder, rectum, sigmoid colon, and small intestine was (168.29±53.80) cGy, (178.87±105.38) cGy, (136.05±78.06) cGy, and (288.91±117.49) cGy, respectively. The median follow-up time was 11 months. Among the 30 patients, there were 12 cases of complete remission,14 cases of partial remission, 3 cases of stable disease, and 1 case of disease progression, with an objective remission rate of 86.7%. None of the patients experienced significant bleeding or pain during treatment. After treatment, 3 patients with recurrent lymph nodes near the rectum developed grade 1 radiation proctitis, which was remitted after treatment. No significant complications were observed in the remaining patients. Conclusion:CT guided percutaneous brachytherapy is safe and feasible for the recurrence of single lesions in the radiated field of cervical cancer.

Objective To explore the bi-directional dynamic associations of bullying perpetration and victimisation with psychopathological symptoms in children and adolescents.Methods The Adolescent Brain Cognitive Development(ABCD)public dataset was used.Three dimensions of bullying perpetration and victimisation and child-adolescent psychopathological symptoms:attention,externalisation and internalisation were collected from 8413 child-adolescents using the peer experiences questionnaire(EPQ)and the brief problem monitoring(BPM)questionnaire,respectively.Bidirectional dynamic associations between bullying and child-adolescent psychopathological symptoms were analysed using cross-lagged networks.Results Bullying implementation to externalising problems was a significant cross-lagged edge(OR=2.36);impulsivity was both the strongest node of out-expected influence(OEI=5.21)and bridge-expected influence(BEI=4.35),and the strongest node of in-expected influence(IEI)was threat of violence(IEI=5.61).Conclusion There is an interaction between bullying and child-adolescent pathology symptoms.Bullying perpetration exacerbates subsequent externalising problems,and impulsivity is the most likely psychopathological symptom to influence both bullying perpetration and externalising internalising problems and it is also the bridging symptom connecting the two.
