Objective:To investigate the expression and clinical significance of microRNA-124(miR-124)and microRNA-1976(miR-1976)in the serum of patients with Parkinson's disease(PD).Methods:A total of 58 patients with PD were selected from September 2020 to June 2022 and categorized as the PD group.The Unified Parkinson's Disease Rating Scale(UPDRS)score was used to divide the PD patients into two groups: those with a UPDRS score≤60(25 patients)and those with a UPDRS score >60(33 patients). The Hoehn-Yahr grading scale was used to grade the PD patients.Additionally, 30 healthy individuals who had undergone a physical examination during the same period were selected as the control group.After collecting the subjects' serum, we performed real-time fluorescent quantitative PCR(qRT-PCR)to detect the expressions of miR-124 and miR-1976 in the serum.Logistic regression analysis was employed to analyze the influencing factors, and the diagnostic significance of serum miR-124 and miR-1976 in PD patients was evaluated using the receiver operating characteristic(ROC)curve.To predict the target genes of miR-1976, we utilized several software including TargetScan and Mirtarbase.Results:Compared to the control group, the PD group showed a significant down-regulation of serum miR-124 expression[(1.49±0.36) vs.(1.02±0.32)]( t=8.85, P<0.001), while miR-1976 expression was sharply up-regulated[(0.98±0.30) vs.(1.33±0.37)]( t=6.92, P<0.001). The low expression of serum miR-124 and the overexpression of miR-1976 were identified as independent risk factors for PD( OR>1, P<0.05). The Hoehn-Yahr rating of PD patients with a UPDRS score above 60 was higher than that of patients with a UPDRS score below 60[(3.42 ± 0.73) vs.(2.16 ± 0.42)]( t=3.05, P<0.05). However, there was no significant difference in serum miR-124 and miR-1976 expression between groups with different UPDRS scores[miR-124: (1.09±0.26) vs.(0.98±0.38)( t=0.89, P>0.05); miR-1976: (1.42±0.43) vs.(1.23±0.68)( t=0.62, P>0.05)]. The ROC analysis results demonstrated that miR-124 and miR-1976 had area under the curve(AUC)values of 0.832 and 0.797, respectively, in diagnosing PD.The corresponding cutoff values were 1.205 and 1.196, respectively.The sensitivity for miR-124 was 74.1%, while for miR-1976 it was 51.8%.The specificity for miR-124 was 77.8%, and for miR-1976 it was 90.1%.When both miR-124 and miR-1976 were combined in the diagnosis of PD, the AUC was 0.912, with a sensitivity of 76.4% and a specificity of 93.2%.Furthermore, it was found that miR-1976 targeted the PINK1 gene, suggesting its potential as a target gene in PD. Conclusions:The expression of miR-124 was found to be decreased in PD patients, while the expression of miR-1976 was increased.Both miR-124 and miR-1976 showed some reference value in PD diagnosis, and their combined diagnostic value was higher.This suggests that further study on their significance is warranted.However, it should be noted that the expressions of miR-124 and miR-1976 were not found to be correlated with the UPDRS score of PD patients.

Objective To explore the efficacy of negative pressure ureteral access sheath combined with disposable flexible ureteroscope(UAS+FRUS)in the treatment of renal calculi of 2-3 cm,so as to provide reference for the treatment.Methods A retrospective analysis was conducted on 130 cases of renal calculi of 2-3 cm treated with surgery in Xiamen Third Hospital during Sep.2021 and Sep.2023,including 68 cases with UAS+FRUS and 62 cases with super-mini percutaneous nephrolithotripsy(SMP).The perioperative indexes and stone-clearance rate(SFR)were compared between the two groups.Results All operations were successful.There were no statistically significant differences in the total SFR and incidence of complications(5.88％vs.9.67％)between the two groups 3 days(88.24％vs.90.32％)and 1 month(91.18％vs.93.55％)after surgery(P＞0.05).For patients with lower calyceal calculi with infundibulopelvic angle(IPA)＜45°,the SFR of the UAS+FRUS group was significantly lower than that of the SMP group(57.14％vs.100％,P＜0.05).The UAS+FRUS group had a longer operation time than the SMP group[(104.94±8.79)minutes vs.(77.98±6.60)minutes,P＜0.001],higher hospitalization costs[(23 112.82±1152.34)yuan vs.(21 975.84±1512.24)yuan,P＜0.001],less postoperative decrease in hemoglobin[(6.71±2.07)g/L vs.(9.81±4.80)g/L,P＜0.001],and shorter postoperative hospitalization time[(3.28±0.51)d vs.(5.58±0.71)d,P＜0.001].The UAS+FRUS group had lower postoperative VAS score at 6,24,and 48 hours than the SMP group[(6.38±0.69)vs.(7.87±0.88);(3.62±0.73)vs.(5.81±0.83)and(3.12±0.33)vs.(3.81±0.60)],with statistical significance(P＜0.05).Conclusion Both surgical methods have a high SFR in the treatment of renal calculi of 2-3 cm.SMP has the advantages of short operation time,low hospitalization costs,and high SFR for lower calyx calculi,while UAS+FURS has the advantages of little bleeding,minimal trauma,and short hospital stay.Surgeons can make reasonable choices based on the patients'condition and willingness,combined with their own surgical experience.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective:To explore the clinical application of the electronic portal imaging device (EPID) based on the linear accelerator produced by Shanghai United Imaging Healthcare Co., Ltd. (UIH) to in vivo dose verification. Methods:A total of 68 patients (32 cases with head and neck tumors, 16 cases with chest tumors, and 20 cases with abdomen and pelvis tumors) who were treated with volumetric modulated arc therapy (VMAT) in the Henan Provincial People′s Hospital were selected in this study. Each patient underwent the pre-treatment dose verification using an Arccheck device (Pre Arccheck), the pre-treatment dose verification using an EPID (Pre EPID), and the in vivo dose verification using an EPID (In vivo EPID). Moreover, the position verification based on fan beam computed tomography (FBCT) was also performed for each patient in the first three treatments and then once a week. The patients were treated when the setup error in any direction ( x: left-right, y: head-foot, z: vertical) was less than 3 mm; otherwise, position correction would be conducted. The three-dimensional setup deviation d was calculated according to setup errors x, y, and z. Results:The γ passing rates of dose verifications Pre EPID and In vivo EPID of 68 patients were (99.97±0.1)% and (94.15±3.84)%, respectively, significantly different from that (98.86±1.48)% of the Pre Arccheck dose verification ( t = -6.12, 9.43; P < 0.05). The γ passing rates of the chest, abdomen and pelvis, and head and neck in the In vivo EPID dose verification showed no significant differences ( P > 0.05). The difference in the γ passing rates (5.56±3.72)% between dose verifications Pre EPID and first In vivo EPID was unrelated to the three-dimensional setup deviation d (1.46±1.51 mm) ( P > 0.05). As the treatment proceeded, the γ passing rate of In vivo EPID gradually decreased from (94.15±3.84)% in the first week to (92.15±3.24)% in the fifth week. From the third week to the fifth week, the γ passing rates of In vivo EPID were significantly different from those in the first week ( t = 2.48, 2.75, 3.09, P < 0.05). Conclusions:The setup errors within 3 mm do not affect the γ passing rate of in vivo dose verification. The clinically acceptable threshold for the γ passing rate of in vivo EPID needs to be further determined. In addition, in vivo dose verification can support the clinical application of adaptive radiotherapy to a certain extent.

Objective To observe the effect of high-frequency repetitive transcranial magnetic stimulation on hemiplegic shoulder pain during convalescence of stroke.Methods A total of 40 patients with hemiplegic shoulder pain during convalescing stroke who were hospitalized in Rehabilitation Medicine Department of Jiaxing Second Hospital from January 2021 to June 2022 were selected and randomly divided into treatment group(rTMS group)and control group(sham rTMS group),with 20 cases in each group.Both groups were given anti-inflammatory and analgesic drugs and conventional rehabilitation treatment.On this basis,the treatment group was combined with rTMS treatment(stimulation frequency was 10.0Hz,stimulation intensity was 80%resting motor threshold,stimulation time was 10s,interval was 50s,total treatment time was 20 minutes,once a day from Monday to Friday,continued treatment 2 days apart,20 times as a course of treatment,a total of 4 weeks),while the control group received sham rTMS.Before treatment,2 and 4 weeks after treatment,numerical pain rating scale(NPRS)was used to assess the degree of shoulder pain,passive shoulder range of motion was measured by protractor,upper limb motor function of hemiplegic side was assessed by Fugl Meyer assessment upper extremity(FMA-UE),and the ability of daily living activities was assessed by modified Barthel index(MBI).Results After treatment,NPRS score of shoulder pain in 2 groups was significantly decreased compared with before treatment(P<0.001),passive shoulder motion and Fugl-Meyer upper limb motor function were significantly improved compared with before treatment(P<0.001),and the treatment group was significantly better than the control group,the difference between groups was statistically significant(P<0.05).The modified Barthel index in 2 groups was significantly improved compared with before treatment(P<0.001),but there was no statistical significance between 2 groups(P>0.05).Conclusion 10.0Hz high-frequency repetitive transcranial magnetic stimulation can significantly relieve hemiplegic shoulder pain during the convalession of stroke,improve the passive range of motion of the affected shoulder,and improve the upper limb motor function of the affected side,but the effect is not significant in improving the ability of daily living activities.

Objective:To evaluate the effects of different doses of sivelestat sodium on perioperative acute lung injury (ALI) in the patients undergoing emergency surgery for acute Stanford type A aortic dissection (AAAD).Methods:A total of 120 patients of both sexes, aged 30-64 yr, with body mass index of 18.5-24.9 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅲ or Ⅳ, scheduled for emergency AAAD surgery, were divided into 3 groups using a random number table method: low-dose sivelestat sodium group (SL group), medium-dose sivelestat sodium group (SM group)and high-dose sivelestat sodium group (SH group), with 40 patients in each group. Sivelestat sodium 4.8, 6.0 and 7.2 mg/kg were intravenously infused starting from 10 min before anesthesia until 24 h after surgery in SL, SM and SH groups, respectively. Blood samples from the radial artery were collected for blood gas analysis after anesthesia induction and before skin incision (T 1), immediately after the end of surgery (T 2), at 24 h after surgery (T 3), and 72 h after surgery (T 4), the alveolar-arterial oxygen tension difference (PA-aDO 2), oxygenation index (OI)and respiratory index (RI) were calculated. The duration of postoperative mechanical ventilation, length of stay in the intensive care unit (ICU) and length of postoperative hospital stay were recorded. Central venous blood samples were collected at T 1-T 4 to measure serum concentrations of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6)and IL-8. Peripheral venous blood samples were collected on preoperative day 1 and postoperative days 1 and 3 to measure white blood cell (WBC) count, neutrophil (NEUT) count, neutrophil percentage (NEUT%), and C-reactive protein (CRP) concentration. The occurrence of postoperative pulmonary complications (PPCs)and 90-day all-cause mortality were recorded. Results:Compared with the baseline at T 1, PA-aDO 2 and RI were significantly increased, OI was decreased, and the serum concentrations of TNF-α, IL-6 and IL-8 were increased at T 2-T 4 in all the three groups ( P<0.05). WBC, NEUT, NEUT% and concentrations of CRP were significantly higher on postoperative days 1 and 3 than on 1 day before surgery in the three groups ( P<0.05). Compared with SL and SM groups, PA-aDO 2 and RI were significantly decreased, OI was increased, and the serum concentrations of TNF-α, IL-6 and IL-8 were decreased, the WBC count, NEUT count, NEUT% and concentrations of CRP were decreased, the incidence of postoperative hypercapnia, hypoxemia, emerging lung rales and bronchospasm was decreased, and the duration of postoperative mechanical ventilation and length of intensive care unit stay were shortened( P<0.05), and no significant change was found in the postoperative length of hospital stay and 90-day all-cause mortality rate in SH group ( P>0.05). Conclusions:Sivelestat sodium 7.2 mg/kg can significantly inhibit the inflammatory responses, alleviate perioperative ALI, and improve early prognosis in the patients undergoing AAAD surgery.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.

Objective:To investigate the clinical efficacy of thoracic endovascular aortic repair (TEVAR) in treating Stanford type B traumatic aortic dissection (TAD).Methods:A retrospective case series study was conducted to analyze the clinical date of 26 patients with Stanford type B TAD admitted to Nantong First People's Hospital from June 2011 to December 2019. There were 21 males and 5 females, aged 35-83 years [(56.2±12.9)years]. All patients mainly suffered from chest and back trauma and were treated with TEVAR. The operation time, intraoperative blood loss, intraoperative heparin dosage, duration of ICU stay and postoperative organ complications were collected. The changes of brain natriuretic peptide, urea nitrogen and creatinine were compared before operation and at one day after operation. The CT angiography (CTA) was performed to mainly detect the location of stent, reverse tearing, paraplegia and internal leakage at 6 months after TEVAR. The aortic CTA was used to measure the maximum diameter of aortic dissecting aneurysm and true lumen diameter of distal aorta before operation and at 6 months after operation, and the diameter changes were compared to determine the aortic remodeling after TEVAR.Results:All patients were followed up for 6-36 months [(25.9±6.3)months]. The operation time was 60-200 minutes [(96.7±30.7)minutes], the intraoperative blood loss was 20-45 ml [(31.1±6.8)ml], the dosage of heparin was 0-0.53 mg/kg [(0.4±0.1)mg/kg], the postoperative ICU stay was 1-7 days [(4.7±1.3)days]. Seven patients developed pulmonary infections after operation and showed significant improvement after closed thoracic drainage, airway management and anti-infection treatment. Two patients had abnormal renal function after operation and received medical therapy for improvement. There was no significant difference in brain natriuretic peptide, urea nitrogen and creatinine between before operation and one day after operation ( P>0.05). At 6 months after operation, the CTA showed that the stent position was satisfactory and there were no serious complications such as reverse tearing and paraplegia. Of one patient with type I endoleak, the tumor did not further expand and his condition was stable. At 6 months after operation, the diameter of dissecting aneurysm [(34.4±5.0)mm] was smaller than that before operation [(38.2±5.6)mm], the true lumen of distal stent [(26.8±4.6)mm] was larger than that before operation [(22.6±6.0)mm] ( P<0.05 or 0.01). Conclusion:For Stanford type B TAD, TEVAR has no significant effect on cardiac function and renal function, with no severe complications and good aortic remodeling.

Objective:To explore the effect of metastatic lymph node ratio (MLR) on the prognosis of adjuvant radiotherapy for stage-Ⅲ gastric cancer patients with no more than 15 lymph nodes dissection.Methods:According to the inclusion and exclusion criteria, a total of 590 patients diagnosed with stage-Ⅲ gastric cancer (excluding adenocarcinoma of esophagogastric junction) were included in this study from the SEER database between 2010 and 2016. No more than 15 lymph nodes were examined in all patients. Among them, 291 patients received surgery combined with adjuvant chemotherapy (surgery + chemotherapy group), and 299 patients received surgery combined with adjuvant radiochemotherapy (surgery + radiochemotherapy group). These two groups were treated with 1∶1 propensity score matching (PSM). We retrospectively analyzed the effect of MLR on prognosis of stage-Ⅲ gastric cancer patients with no more than 15 lymph nodes dissection, and evaluated the significance of postoperative adjuvant radiotherapy among patients with different MLR.Results:According to the analysis result of area under curve (ROC), 0.5 was defined as the best cut-off point of MLR. In the two groups of patients with stage-Ⅲ gastric cancer included in the study, the median survival time was 23 months in the surgery + radiochemotherapy group, and the 1 -, 3 -, and 5-year overall survival (OS) ratio were 77.1%, 33.2% and 22.8%, respectively. The median survival time was 21 months in the surgery + chemotherapy group, and the 1 -, 3 -, and 5-year OS ratio were 72.2%, 33.6% and 23.1%, respectively. There was no statistically significant difference between the two groups in OS. The result of subgroup analysis showed that there was no statistically significant difference in OS between the surgery + radiochemotherapy group and the surgery + chemotherapy group among patients with MLR≤0.5, while OS of the surgery + radiochemotherapy group was significantly better than the surgery + chemotherapy group among patients with MLR>0.5( χ2=8.542, P < 0.05). Multivariate Cox regression analysis showed that race, T stage, N stage, MLR and adjuvant radiotherapy were the important factors affecting OS of stage-Ⅲ gastric cancer patients with no more than 15 lymph nodes dissection( Wald=8.544, 7.547, 10.925, 18.047, 10.715, P < 0.05). After PSM, there was no statistically significant difference in OS between the two groups. The result of subgroup analysis showed that there was no statistically significant difference in OS between the surgery + radiochemotherapy group and the surgery + chemotherapy group among patients with MLR≤0.5, while OS of the surgery + radiochemotherapy group was significantly better than the surgery + chemotherapy group among patients with MLR>0.5( χ2=6.944, P < 0.05). Multivariate Cox regression analysis showed that race, T stage, N stage, MLR and adjuvant radiotherapy were the important factors affecting OS of stage-Ⅲ gastric cancer patients with no more than 15 lymph nodes dissection ( Wald=7.154, 8.023, 7.744, 17.016, 4.149, P < 0.05). The result of prognosis analysis of two groups before and after PSM were consistent. Conclusions:MLR is an important prognostic factor for stage-Ⅲ gastric cancer patients with no more than 15 lymph nodes dissection. The OS of patients with MLR ≤ 0.5 can′t benefit from postoperative adjuvant radiotherapy, while patients with MLR > 0.5 should be advised to receive postoperative adjuvant radiotherapy to improve the prognosis.
