OBJECTIVE: To investigate the surgical method and short-term effectiveness of arthroscopy edge-to-edge #-shaped suture in the treatment of the complete radial tear of the lateral meniscus body. METHODS: The clinical data of 13 patients with complete radial tear of lateral meniscus body between May 2020 and August 2023 were retrospectively analyzed. There were 10 males and 3 females, aged 15-38 years (mean, 24.2 years). There were 11 cases of acute injury and 2 cases of chronic injury, with time from injury to admission ranging from 2 days to 5 months. All patients had tenderness in the lateral joint space, and 2 patients with chronic injury had positive McMurray's sign. All patients were treated with arthroscopic edge-to-edge #-shaped suture technique. The knee joint activity and tenderness in the lateral joint space were detected, and the healing of the incision and the occurrence of complications were observed. X-ray films and MRI of the knee joint were performed to evaluate joint degeneration and meniscus healing. Lysholm score, International Knee Documentation Committee (IKDC) subjective score, Tegner score, and visual analogue scale (VAS) score were used to evaluate the functional recovery before and after operation. RESULTS: The operation time ranged from 46 to 100 minutes (mean, 80.08 minutes). All the incisions healed by first intention, and no complication such as intraoperative vascular and nerve injury or postoperative infection occurred. All 13 patients were followed up 20-59 months (mean, 29.3 months). All patients had no limitation of knee extension and flexion. One patient with chronic injury continued to have tenderness in the lateral space of the knee joint, while the remaining patients had no tenderness, swelling, and locking in the lateral space. Immediate postoperative MRI of knee joint showed continuous recovery of the lateral meniscus. At last follow-up, no degenerative changes were observed in X-ray films of knee joint. Except for 1 patient with chronic injury, the MRI of the other patients showed the healing performance after lateral meniscus suture. Lysholm score, IKDC subjective score, Tegner score, and VAS score all significantly improved when compared with those before operation (P<0.05). CONCLUSION The edge-to-edge #-shaped suture technique can effectively repair the complete radial tear of the lateral meniscus body, and the short-term effectiveness is satisfactory.

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.

Venous thromboembolism (VTE) is a complication in children with acute lymphoblastic leukemia (ALL). The Chinese Children's Cancer Group-ALL-2015 protocol was carried out in China, and epidemiology, clinical characteristics, and risk factors associated with VTE were analyzed. We collected data on VTE in a multi-institutional clinical study of 7640 patients with ALL diagnosed in 20 hospitals from January 2015 to December 2019. First, VTE occurred in 159 (2.08%) patients, including 90 (56.6%) during induction therapy and 108 (67.92%) in the upper extremities. T-ALL had a 1.74-fold increased risk of VTE (95% CI 1.08-2.8, P = 0.022). Septicemia, as an adverse event of ALL treatment, can significantly promote the occurrence of VTE (P < 0.001). Catheter-related thrombosis (CRT) accounted for 75.47% (n = 120); and, symptomatic VTE, 58.49% (n = 93), which was more common in patients aged 12-18 years (P = 0.023), non-CRT patients (P < 0.001), or patients with cerebral thrombosis (P < 0.001). Of the patients with VTE treated with anticoagulation therapy (n = 147), 4.08% (n = 6) had bleeding. The VTE recurrence rate was 5.03% (n = 8). Patients with VTE treated by non-ultrasound-guided venous cannulation (P = 0.02), with residual thrombus (P = 0.006), or with short anticoagulation period (P = 0.026) had high recurrence rates. Thus, preventing repeated venous puncture and appropriately prolonged anticoagulation time can reduce the risk of VTE recurrence.

ObjectiveTo investigate the clinical efficacy of Guizhi Shaoyao Zhimutang （GZSYZM） combined with fire needling in the treatment of periarthritis of shoulder with wind-cold-dampness impediment syndrome by stimulating pain points and "shoulder three acupoints". MethodA total of 120 patients with periarthritis of shoulder with wind-cold-dampness impediment syndrome， admitted to Hainan General Hospital from August 2020 to August 2022， were randomly divided into two groups using a random number table. The control group （60 cases） received treatment with GZSYZM for two weeks， while the observation group （60 cases） received treatment with GZSYZM combined with fire needling at pain points and "shoulder three acupoints" for two weeks. The clinical efficacy， adverse reactions， shoulder pain intensity， shoulder joint function， and levels of calcitonin gene-related peptide （CGRP）， cyclooxygenase-2 （COX-2）， interleukin （IL）-2， and IL-17 before and after treatment were compared between the two groups. ResultThe total effective rate in the observation group was 88.33% （53/60）， significantly higher than 68.33% （41/60） of the control group （χ²=7.070， P<0.01）. Compared with the results before treatment， both groups showed significant reductions in pain rating index （PRI）， visual analog scale （VAS） scores， present pain intensity （PPI）， and Simplified McGill Pain Questionnaire （SF-MPQ） total scores， as well as serum levels of CGRP， COX-2， IL-2， and IL-17 after treatment （P<0.01）， and improved pain intensity， daily life abilities， joint mobility， muscle strength， and Constant-Murley score （P<0.01）. Compared with the control group after treatment， the observation group showed significantly reduced PRI， VAS score， PPI， SF-MPQ total score， as well as serum levels of CGRP， COX-2， IL-2， and IL-17 （P<0.01）， and increased pain intensity， daily life abilities， joint mobility， muscle strength， and Constant-Murley score （P<0.01）. There was no significant difference in the incidence of adverse reactions between the two groups. ConclusionGZSYZM combined with fire needling at pain points and "shoulder three acupoints" can effectively reduce the levels of serum inflammatory factors and pain mediators， alleviate pain， and improve shoulder joint function in patients with periarthritis of shoulder with wind-cold-dampness impediment syndrome.

Objective:To investigate the effect of exercise rehabilitation on frailty of elderly patients with coronary heart disease after percutaneous coronary intervention (PCI) .Methods:From January to December 2021, 80 elderly patients with coronary heart disease who received PCI in Qinhuai Medical Area of General Hospital of Eastern Theater Command were selected as the study subject by convenience sampling. A total of 39 patients from January to June 2021 were set in the control group, and 41 patients from July to December 2021 were set in the experimental group. The control group was given routine nursing, and the experimental group was given systematic exercise rehabilitation on the basis of the control group. The effects of intervention were evaluated by Tilburg Frailty Index (FI) , Cardiac Exercise Self-Efficacy Instrument (CESEI) , cardiac function, exercise tolerance, and 6-minute Walking Distance (6MWD) .Results:There was no significant difference in FI and CESEI scores between the two groups before intervention ( P>0.05) . After intervention, the FI score of patients in the experimental group was lower than that in the control group, and the CESEI score was higher than that in the control group, with statistically significant differences ( P<0.05) . There was no significant difference in cardiac function, exercise tolerance and 6MWD between the two groups before intervention ( P>0.05) . After intervention, there were statistically significant differences in cardiac function, exercise tolerance and 6MWD between the two groups ( P<0.05) . Conclusions:Exercise rehabilitation can effectively alleviate the frailty of elderly patients with coronary heart disease after PCI, improve their exercise compliance, cardiac function and exercise tolerance, which is worthy of clinical promotion.

Objective:To analyze the research hotspots of the application of mobile health in cardiac function monitoring of patients with heart disease and to conduct a visual analysis.Method:Subject field retrieval was carried out based on Web of Science Core Collection. The retrieval time range was set from 2000 to 2022, and the type of paper was limited to treatise. The retrieved literatures were imported into Endnote 7 for screening, and the repetitive and unrelated literatures were excluded. A total of 291 literatures were included in this study. Open refine 2.8 was used for data cleaning of synonyms and then VOSviewer 1.6.18 was used for visualization analysis of country/region, author and keywords.Results:Research reports on the application of mobile medical in the field of cardiac function monitoring in patients with heart disease have been growing steadily since 2005, and the number of articles published in the field increased rapidly from 2020 to 2021. The top five countries with the highest number of publications were the United States (71) , Australia (20) , China (18) , the United Kingdom (14) and Sweden (13) . The cooperation and exchange among global researchers were relatively close, but they were still dominated by regional cooperation and had not formed a large core group of authors. A total of 71 high-frequency keywords were included, and the top five were mhealth (30 times) , heart failure (27 times) , smartphone (26 times) , telemedicine (15 times) and mobile phone (17 times) . Each cluster keyword was related to each other, which represented the current research hotspot content respectively.Conclusions:At present, number of publications in China ranks first in the world, but there is still a big gap compared with the United States. The development and optimization of monitoring equipment and mobile medical APP have become the focus and hot topics.

Objective: To evaluate the long-term efficacy and prognostic factors of childhood acute lymphoblastic leukemia (ALL) enrolled in Shanghai Children's Medical Center-Acute Lymphoblastic Leukemia-2005(SCMC-ALL-2005) multicenter study. Methods: Between May 2005 and December 2014, 1 497 newly diagnosed ALL patients were enrolled and treated in 5 hospitals of SCMC-ALL-2005 study group, using risk-stratified SCMC-ALL-2005 protocol. Risk group classification and treatment intensity were based on clinical features, genetic abnormalities, early response to treatment and levels of minimal residual disease (MRD). Kaplan-Meier method was used to generate overall survival (OS) and event-free survival(EFS) curves. Cox proportional hazards models were used for multivariate analyses. Results: The patients were followed up to December 31, 2016, the median follow-up time was 69 months (24-141 months). The 5-year and 10-year OS rates were (80.0±1.0)% and (76.0±2.0)%. The 5-year and 10-year EFS rates were (69.0±1.0)% and (66.0±2.0)%. The 5-year and 10-year relapse rates were (23.0±1.0)% and (25.0±2.0)%. The 5-year OS and EFS for low risk (LR), intermediate risk (IR) and high risk (HR) were (91.1±1.4)% and (83.3±1.8)%, (79.2±1.5)% and (68.9±1.7)%, (52.9±4.4)% and (30.0±3.8)%, respectively. MRD negative status (<0.01%) on day 55 was seen in 792 patients (82.8%) and positive MRD on day 55 was associated with poor prognosis (OR=1.9, 95%CI: 1.3-2.7, P=0.001). Twenty-four HR patients received allogeneic hematopoietic stem cell transplantation and 17(70.8%) of them were alive and in remission. A total of 164 severe adverse events occurred, 46 of them died, treatment-related mortality was 3.1%. Conclusions In this large sample research, the overall outcome for multi-center SCMC-ALL-2005 study was favorable. This helps to promote the standardized treatment of childhood ALL to the whole country. MRD results on day 55 of induction therapy have important prognostic and therapeutic implications.

Acute ischemic stroke (AIS), as the third leading cause of death worldwide, is characterized by its high incidence, mortality rate, high incurred disability rate, and frequent reoccurrence. The neuroprotective effects of Ginkgo biloba extract (GBE) against several cerebral diseases have been reported in previous studies, but the underlying mechanisms of action are still unclear. Using a novel in vitro rat cortical capillary endothelial cell-astrocyte-neuron network model, we investigated the neuroprotective effects of GBE and one of its important constituents, Ginkgolide B (GB), against oxygen-glucose deprivation/reoxygenation and glucose (OGD/R) injury. In this model, rat cortical capillary endothelial cells, astrocytes, and neurons were cocultured so that they could be synchronously observed in the same system. Pretreatment with GBE or GB increased the neuron cell viability, ameliorated cell injury, and inhibited the cell apoptotic rate through Bax and Bcl-2 expression regulation after OGD/R injury. Furthermore, GBE or GB pretreatment enhanced the transendothelial electrical resistance of capillary endothelial monolayers, reduced the endothelial permeability coefficients for sodium fluorescein (Na-F), and increased the expression levels of tight junction proteins, namely, ZO-1 and occludin, in endothelial cells. Results demonstrated the preventive effects of GBE on neuronal cell death and enhancement of the function of brain capillary endothelial monolayers after OGD/R injury in vitro; thus, GBE could be used as an effective neuroprotective agent for AIS/reperfusion, with GB as one of its significant constituents.

A novel recombinant Bacille Calmette-Guerin (rBCG) vaccine co-expressed Eimeria tenella rhomboid and cytokine chicken IL-2 (chIL-2) was constructed, and its efficacy against E. tenella challenge was observed. The rhomboid gene of E. tenella and chIL-2 gene were subcloned into integrative expression vector pMV361, producing vaccines rBCG pMV361-rho and pMV361-rho-IL2. Animal experiment via intranasal and subcutaneous route in chickens was carried out to evaluate the immune efficacy of the vaccines. The results indicated that these rBCG vaccines could obviously alleviate cacal lesions and oocyst output. Intranasal immunization with pMV361-rho and pMV361-rho-IL2 elicited better protective immunity against E. tenella than subcutaneous immunization. Splenocytes from chickens immunized with either rBCG pMV361-rho and pMV361-rho-IL2 had increased CD4+ and CD8+ cell production. Our data indicate recombinant BCG is able to impart partial protection against E. tenella challenge and co-expression of cytokine with antigen was an effective strategy to improve vaccine immunity.
