ObjectiveTo evaluate the effectiveness of stone needle thermocompression and massage compared to flurbiprofen gel patch in relieving chronic musculoskeletal pain in the shoulder and back， and to explore the potential mediating mechanism through muscle elasticity. MethodsA total of 120 patients with chronic musculoskeletal pain in the shoulder and back were randomly assigned to either stone needle group or flurbiprofen group， with 60 patients in each. The stone needle group received stone needle thermocompression and massage for 30 minutes， three times per week； the flurbiprofen group received flurbiprofen gel patch twice daily. Both groups were treated for 2 weeks. Pain improvement， as the primary outcome， was assessed using the Global Pain Scale （GPS） at baseline， after 2 weeks of treatment， and again 2 weeks post-treatment. To explore potential mechanisms， a mediator analysis was conducted by measuring changes in superficial and deep muscle elasticity using musculoskeletal ultrasound at baseline and after the 2-week treatment period. ResultsThe stone needle group showed significantly greater pain relief than the flurbiprofen group 2 weeks post-treatment. After adjusting for confounders related to pain duration， the between-group mean difference was -8.8 ［95% CI （-18.2， -0.7）， P＜0.05］. Part of the therapeutic effect was mediated by changes in deep muscle elasticity， with a mediation effect size of -1.5 ［95% CI （-2.0， -0.9）， P = 0.024］， accounting for 17.9% of the total effect. ConclusionStone needle thermocompression and massage can effectively relieve chronic musculoskeletal pain in the shoulder and back， partly through a mediating effect of improved deep muscle elasticity.

Objective:To examine the risk factors and predictive value of depression following mild acute ischemic stroke in elderly individuals.The aim is to enhance early identification and intervention, ultimately leading to improved prognosis.Methods:A case-control study was conducted on 988 elderly patients with mild acute ischemic stroke.The study collected general population and social data, as well as clinical laboratory data such as blood glucose, blood lipids, and AD7C-NTP in urine.Additionally, the patients underwent assessments using the Montreal Cognitive Assessment Scale(MoCA), National Institutes of Health Stroke Scale(NHISS), Barthel index(BI), Hamilton Anxiety Scale(HAMA), and Hamilton Depression Scale(HAMD).Based on the HAMD depression scale score, the patients were divided into a nopost-stooke depression(NPSD)group and a post-stooke depression(PSD)group.The study then analyzed the related risk factors and predictive value of PSD.Results:A total of 988 patients were eligible for inclusion, with 132 being excluded and 856 being included.The NPSD and PSD groups showed significant differences in age, hypertension, smoking history, education level, and stroke history(all P<0.05).Regarding clinical data, there were statistically significant differences between the two groups in total cholesterol(TC), triacylglycerol(TG), HDL, urinary AD7C-NTP, MoCA, and HAMA scores(all P<0.05).The results of the multi-factor logistic regression analysis revealed that gender( OR=1.975, 95% CI: 1.223-3.190, P=0.005), stroke history( OR=1.352, 95% CI: 0.877-2.086, P=0.042), and HAMA score( OR=1.216, 95% CI: 0.932-1.526, P=0.043)were identified as independent risk factors for post-stroke depression in the elderly.Conversely, MoCA score( OR=0.873, 95% CI: 0.814-0.937, P<0.001)was found to be an independent protective factor.Furthermore, the ROC curve analysis demonstrated that the HAMA score(AUC=0.892, sensitivity: 0.721, specificity: 0.854, cut-off value: 9.5)exhibited significant predictive value, while the other indexes had limited predictive value. Conclusions:Gender, stroke history, and HAMA score have been identified as potential independent risk factors for post-stroke depression(PSD)in the elderly, while MoCA score may serve as an independent protective factor.Notably, HAMA score demonstrates a strong predictive ability for PSD.Early identification of these factors and timely intervention could significantly contribute to improving prognosis.

Objective:To summarize the ultrasonographic features and prognosis of fetal persistent vitelline artery.Methods:The prenatal ultrasound features, genetic testing results, and prognosis of a fetus with an isolated persistent vitelline artery that was diagnosed in our hospital in December 2021 were retrospectively analyzed. Relevant articles were retrieved from CNKI, VIP, Wanfang, Yiigle, PubMed, Embase, and UpToDate databases using the terms "persistent vitelline artery", "type Ⅱ single umbilical artery", and "prenatal ultrasound" in both Chinese and English. Prenatal ultrasound features and prognosis of the persistent vitelline artery in fetuses were summarized using descriptive statistical analysis.Results:(1) Case report: In this case, ultrasound at 23 gestational weeks showed that an abnormally large blood vessel deriving from the celiac artery near the superior mesenteric artery entered the placenta through the umbilical opening in parallel with the umbilical vein. Color Doppler showed a blood flow spectrum like that in the umbilical artery. The transverse section image showed that bilateral umbilical arteries were not observed in the bladder and the free segment of the umbilical cord was in the shape of the Chinese character "Lyu". No obvious other structural abnormalities and a negative result of genetic testing were observed in the fetus. Followed up to one year old, the patient showed normal growth and development. (2) Literature review: A total of five articles involving four cases were retrieved (three in English and two in Chinese). Among the five cases, including the present case, one was terminated due to left renal agenesis and abnormal heart arteries ratio revealed by prenatal ultrasound, and the remaining four cases without obvious structural abnormalities in the prenatal ultrasound were born and developed well. Histopathological examination of the umbilical cord was performed in three cases, of which two with persistent vitelline artery had a distinct internal elastic lamina, and one with remained vitelline duct.Conclusions:The prenatal ultrasound of fetal persistent vitelline artery is typically characterized by an abnormal vessel that is derived from the abdominal aorta or superior mesenteric artery and plays the function of the umbilical artery. The prognosis of the isolated persistent vitelline artery is good, but a better understanding of such embryonic abnormalities is needed as there are few relevant reports at home and abroad.

Objective:To investigate the clinicopathological features, mutation, therapeutic efficacy and the factors influencing the prognosis of patients with cardiac diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was performed. The clinical data of 11 cardiac DLBCL patients in Ruijin Hospital of Shanghai Jiao Tong University School of Medicine from January 2016 to October 2020 were retrospectively analyzed. NovaSeq sequencing platform was used to detect gene mutations in 5 patients, and bioinformatics analysis of sequencing data was conducted through public database to identify the mutation sites of pathogenic genes. Kaplan-Meier method was used to analyze the progression-free survival (PFS) and the overall survival (OS). Univariate Cox proportional risk model was used to analyze the influencing factors of prognosis.Results:Among 11 patients with cardiac DLBCL, 5 were male and 6 were female. The age [ M ( Q1, Q3)] was 61 years (45 years, 70 years). All 11 patients were non-germinal center B-cell (non-GCB) type. There were 2 primary cases and 9 secondary cases; 9 cases with Ann Arbor stage of Ⅲ-Ⅳ, 10 cases with increased lactate dehydrogenase (LDH) and 9 cases with international prognostic index (IPI) score equal to or higher than 3 scores. Among 11 patients, 9 cases received a first-line treatment based on the R-CHOP (rituximab, cyclophosphamide, epirubicin/doxorubicin hydrochloride liposomes, vincristine and prednisone) regimen, of which 8 patients achieved complete remission (CR), and 1 patient achieved stable disease (SD); 1 patient received IR2 (ibrutinib + rituximab + lenalidomide) treatment regimen and achieved SD, and 1 patient received supportive treatment only and achieved progression of the disease. The follow-up time was 39.9 months (25.6 months, 57.3 months). The 3-year PFS rate and 3-year OS rate of 11 patients was 54.5%, 77.9 %, respectively. Univariate Cox regression analysis showed that gender, B symptoms, Ann Arbor stage, LDH level, number of extranodal lesions, IPI score were not correlated with PFS and OS of patients (all P > 0.05). Among 5 cases undergoing gene detection, KMT2D mutations and PIM1 mutations were detected in 2 cases,respectively. Interestingly, KMT2D mutations were only found in secondary cardiac DLBCL patients (2/3), while PIM1 mutations were only detected in primary cardiac DLBCL patients (2/2). Conclusions:Most cardiac DLBCL patients are non-GCB type and have advanced clinical stage, while may benefit from R-CHOP treatment regimen. PIM1 and KMT2D are the commonly mutated genes in cardiac DLBCL.

Objective To explore whether dexmedetomidine(DEX)can alleviate exertional heatstroke(EHS)-induced rhabdomyolysis(RM)in rats by activating adrenergic α2 receptors,and to explore its potential mechanism based on the reactive oxygen species(ROS)/NOD-like receptor protein 3(NLRP3)/interleukin-1β(IL-1β)pathway.Methods Thirty-six male Sprague-Dawley(SD)rats,after a 7-day acclimatization training,were randomly divided into six groups:control group(CN group),EHS group,low-dose DEX group(EHS+low DEX group),high-dose DEX group(EHS+high DEX group),DEX combined with yohimbine(YOH)group(EHS+high DEX+YOH group),and YOH group(EHS+YOH),with six rats in each group.Before modeling,EHS+high DEX+YOH group and EHS+YOH group were intraperitoneally injected with YOH at 1 mg/kg,while the other four groups were injected intraperitoneally with an equal dose of physiological saline(0.9%NS).During modeling,except for CN group,the other 5 groups of rats were subjected to heat exercise in a high-temperature and high-humidity chamber to construct an EHS rat model.After successful modeling,EHS+low DEX group was intraperitoneally injected with DEX at 10 μg/kg,EHS+high DEX group and EHS+high DEX+YOH group were intraperitoneally injected with DEX at 30 μg/kg,and CN group,EHS group and DEX+YOH group were intraperitoneally injected with equal doses of saline.After 6 h of observation,all rats were anesthetized,and their blood from the abdominal aorta and gastrocnemius muscle tissue were taken.Enzyme-linked immunosorbent assay(ELISA)was used to detect the expression levels of serum tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),IL-1β and myoglobin(MB)in rats;biochemical assay kit was used to measure the level of creatine kinase(CK)in rat serum;HE staining was used to observe pathological changes in rat gastrocnemius muscle tissues;transmission electron microscopy was used to observe ultrastructural changes in gastrocnemius muscle;2′,7′-dichlorofluorescent yellow diacetate(DCFH-DA)fluorescent probe was used to detect the level of reactive oxygen species(ROS);and Western blotting was performed to detect the expression levels of NOD-like receptors 3(NLRP3),aspartic protease-1(caspase-1)and adrenergic α2A receptor(ADRA2A).Results Compared with CN group,the levels of serum IL-6,IL-1β,TNF-α,CK and MB in EHS group rats were significantly elevated(P<0.01).HE staining results revealed that the gastrocnemius muscle tissues of rats in EHS group had these pathological manifestations such as disarray of muscle fibrous structure,hemorrhage,edema,and infiltration of inflammatory cells.Transmission electron microscopy results showed that the ultrastructure of the gastrocnemius muscle in EHS group exhibited myofibroblasts with swelling and enlarging in size,cytoplasmic vacuolization,and mitochondria with obvious swelling,degranulation,and disappearance of double cristae.Compared with CN group,the expression levels of ROS,NLRP3,and caspase-1 in gastrocnemius of rats in EHS group significantly increased(P<0.01);Compared with EHS group,the levels of TNF-α,IL-6,IL-1β,CK,MB and the expression levels of ROS,NLRP3,caspase-1 in gastrocnemius tissue of rats in EHS+low DEX group and EHS+high DEX group decreased in a dose-dependent manner(P<0.05),and the pathological damage observed with HE staining and transmission electron microscopy was alleviated by DEX.After YOH pretreatment,compared with the EHS+high DEX group,the serum levels of TNF-α,IL-6,IL-1β,CK,MB and ROS,NLRP3 and caspase-1 in the gastrocnemius muscle tissue of rats in EHS+high DEX+YOH group relatively increased(P<0.05),and the pathological damage observed with HE staining and transmission electron microscopy was exacerbated.The expression of ADRA2A in gastrocnemius muscle of EHS group significantly decreased compared with CN group(P<0.01),and the expression of ADRA2A in muscle of rats in DES+low DEX group and EHS+high DEX group was higher than that in EHS group(P<0.05).Conclusions DEX can alleviate EHS-induced RM by activating ADRA2A,potentially through inhibiting the ROS-dependent NLRP3/IL-1β inflammatory pathway.

Objective:To explore the effect of motivational enhancement group intervention conducted by nur-ses on the motivation of self-improvement,relapse tendency and self-esteem in the recovering male amphetamine addicts.Methods:Ninety-eight recovering male amphetamine addicts in the Compulsory Detoxification Center were randomly divided into control group(n=54)and motivational enhancement group(n=44).The addicts in the con-trol group received routine education while those in the motivational enhancement group received routine education combined with a 12-week motivational enhancement group intervention conducted by nurses.The Stages of Change Readiness and Treatment Eagerness Scale(SOCRATES),Relapse Tendency Questionnaire,and Rosenberg Self-es-teem Scale(RSES-T)were applied to measure the effect,before and after the intervention.Results:In both two groups,the scores of RSEST,questionnaire of relapse tendency,and self-confidence of detoxification were lower af-ter 12-week intervention than at the baseline(Ps＜0.05).After 12-week intervention,all the above scores were lower in the motivational enhancement group than in the control group(Ps＜0.05).Conclusion:Compared with routine education,the motivational enhancement group intervention conducted by nurses may be more effective to improve their self-confidence in drug rehabilitation and prevention of relapse in recovering male amphetamine ad-dicts,however,the improvement on self-esteem is limited.

Aim To investigate the effects of berberine(BBR)combined with 5'-n-ethylformamidoadenosine(NECA)on myocardial H9c2 and HL-1 cell damage induced by hypoxia/reoxygenation(H/R).Methods H9c2 and HL-1 cells were divided into the Control group,BBR group,NECA group,combined administra-tion group,H/R group,BBR+H/R group,NECA+H/R group,and combined administration+H/R group.CCK-8 was used to detect cell viability in each group.The TMRE kit was used to detect MMP.DCFH-DA was used to detect ROS content.The Mito SOX Red fluorescent probe was used to detect mitochondrial su-peroxide.The expressions of COX Ⅳ,Tom20,and Tim23 were detected by Western blot.The expression of COX Ⅳ and Tom20 genes was detected by qRT-PCR.Results In H9c2 cells,the cell viability and TMRE fluorescence intensity in the H/R group were significantly decreased compared with the Control group.The protein expressions of COX Ⅳ,Tom20,and Tim23,gene expressions of COX Ⅳ and Tom20,ROS,and mitochondrial superoxide contents were significant-ly increased.Compared with the H/R group,the cell viability of BBR and NECA were enhanced after ad-ministration alone.The contents of ROS and mitochon-drial superoxide were significantly decreased.In HL-1 cells,cell viability in the H/R group was significantly decreased compared with the Control group.The con-tents of ROS and mitochondrial superoxide were signifi-cantly increased.Compared with the H/R group,BBR and NECA alone and combined administration en-hanced cell viability.The contents of ROS and mito-chondrial superoxide were significantly decreased.Conclusion The administration of BBR and NECA a-lone or in combination can reduce the production of mi-tochondrial superoxide and cell ROS,thereby allevia-ting mitochondrial damage,alleviating oxidative stress damage,and ultimately reducing H/R-induced myocar-dial cell damage.

Objective:To compare the lateral veneer fixation versus the tunnel fixation for reconstruction of the medial patellofemoral ligament (MPFL) in the treatment of recurrent patellar dislocation in adolescents.Methods:A retrospective study was conducted to analyze the data of 50 adolescent patients with recurrent patellar dislocation who had been treated at Department of Pediatric Orthopedics, The Sixth Affiliated Hospital of Xinjiang Medical University from January 2020 to January 2023. There were 12 males and 38 females with an age of (15.0±0.9) years, and 23 cases on the left and 27 cases on the right. The number of preoperative dislocations was (2.5±0.9) times. According to the surgical methods, the patients were divided into 2 groups: a veneer group of 25 cases whose MPFL was reconstructed by the patellar lateral veneer fixation, and a tunnel group of 25 cases whose MPFL was reconstructed by the patellar tunnel fixation. The 2 groups were compared in terms of Kujala score, Lysholm score, lateral patellofemoral angle (LPFA), congruence angle (CA), patellar tilt angle (PTA), and lateral patellar displacement (LPT) at the last follow-up.Results:As the differences in the preoperative general data between the groups were insignificant, the 2 groups were comparable ( P>0.05). The 50 patients were followed up for (24.1±5.1) months after surgery. There were no complications like patellar fracture or limitation of joint flexion-extension in either group after surgery, and neither group experienced any further patellar dislocation at the last follow-up. The Kujala score, Lysholm score, LPFA, CA, PTA and LPT at the last follow-up were (87.8±4.3) points, (88.3±4.7) points, 9.5°±1.1°, 10.8°±1.4°, 9.6°±1.0°, and 9.2±1.3 mm in the veneer group, and (86.0±4.4) points, (87.7±4.2) points, 9.5°±1.1°, 11.0°±1.6°, 9.0°±1.8°, and (9.2±1.3) mm in the tunnel group, respectively, showing no statistically significant difference between the 2 groups ( P>0.05). However, there were significant improvements within each group in the comparisons of the above indexes between pre-surgery and the last follow-up ( P<0.05). Conclusion:In the treatment of recurrent patellar dislocation in adolescents, both lateral veneer fixation and tunnel fixation to reconstruct the MPFL can improve the alignment of the patellofemoral joint in adolescents, contributing to the improvement of knee joint function and patellar stability.

Objective:To analyze the incidence and clinical phenotype of the concomitant extragenital malformations in the patients with female reproductive tract anomalies.Methods:A retrospective study was conducted using clinical data of hospitalized patients diagnosed with uterine, cervical, or vaginal malformations from January 2003 to December 2022 in Peking Union Medical College Hospital. The malformations were classified according to American Society for Reproductive Medicine müllerian anomalies classification 2021, and in each type, the incidence and specific manifestations of concomitant extragnital malformations were analyzed.Results:A total of 444 patients were included. The overall incidence of concomitant extragenital malformations was 43.5% (193/444), including urinary system, skeletal system, and other system malformations. Renal malformations on the obstructed side were present in all patients with oblique vaginal septum syndrome (100.0%, 78/78). The total incidence of concomitant extragnital malformations was as high as 8/11 in uterus didelphys, 43.5% (10/23) in unicornuate uterus, 33.6% (79/235) in Mayer-Rokitansky-Küster-Hauser syndrome, 18.8% (6/32) in septate uterus and 18.5% (12/65) in cervical agenesis. Urinary system malformations (30.6%, 136/444) and skeletal system malformations (13.5%, 60/444) were the most common concomitant malformations in all types, in which, unilateral renal agenesis and scoliosis were the most common.Conclusions:Urinary and skeletal system malformations are important features of female reproductive tract anomalies. Urologic ultrasonography and spinal roentgenogram are recommended for all patients with female reproductive tract anomalies.

To evaluate the effectiveness and safety of implantable D-shant atrial shunt device in patients with severe pulmonary arterial hypertension(PAH)and right heart failure.A 53-year-old female patient diagnosed with severe idiopathic PAH and right heart failure,her WHO FC grade was Ⅳ.The right heart catheter and implantation of D-shant atrial shunt device were performed under local anesthesia on November 30,2021.A 6 mm×4 cm peripheral artery balloon was selected to dilate the atrial septum and a D-shant atrial shunt device with a fixed 4 mm diameter orifice was implanted into the heart.The clinical symptoms and hemodynamics of the patient was improved after the intervention.Implantation of atrial shunt device as a palliative therapy to established a right to left shunt is another strategy for treating patients with severe PAH in late period,which has good effectiveness and safety.It could be the last replacement therapy to improve symptoms and prolonged lives to drug resistant and severe PAH patients.
