Objective To observe the clinical efficacy of Zhuanyaotang Granules for the treatment of degenerative lumbar spinal stenosis(DLSS).Methods Using a randomized double blind controlled design,104 DLSS patients were divided into an experimental group and a control group using a random number table method,with 52 patients in each group.The treatment group took oral Zhuanyaotang Granules,methylcobalamin tablets and celecoxib capsule simulants.The control group used Zhuanyaotang Granules simulants,methylcobalamin tablets and celecoxib capsules.The course of treatment was 3 weeks for both groups.The follow-ups were conducted at 1 month and 3 months after treatment.The intermittent claudication distance,visual analogue scale(VAS)score and JOA efficacy rating criteria for low back pain score were observed in both groups before treatment,1,2,3 weeks of treatment and 1 month after treatment and 3 months after treatment.Adverse reactions during treatment were recorded.Results There were 5 cases of detachment and 2 cases of exclusion in the experimental group,and 5 cases of detachment and 1 case of exclusion in the control group.Compared with before treatment,there were statistically significant differences in intermittent claudication distance,VAS score,and JOA score between the two groups of patients at various time points during treatment and follow-up(P<0.05);there was no statistically significant difference in intermittent claudication distance,VAS score,and JOA score between the experimental group and the control group before treatment and 1 and 2 weeks of treatment(P>0.05);compared with the two groups at 3 weeks of treatment and 1 and 3 months after treatment,the intermittent claudication distance and JOA score in the experimental group were lower than those in the control group(P<0.05);There was no significant difference in VAS score between the two groups and the control group after 3 weeks of treatment(P>0.05).There were 2 adverse reactions(4.4%)in the experimental group and 5 adverse reactions(10.8%)in the control group,without statistical significance(P>0.05).Conclusion Zhuanyaotang Granules can effectively relieve pain and improve lumbar function in patients with DLSS,which is more effective and safer than oral celecoxib capsules and methylcobalamin tablets.

Objective:To verify the predictive value of the Second Revision of the International Staging System (R2-ISS) in newly diagnosed patients with multiple myeloma (MM) who underwent first-line autologous hematopoietic stem cell transplantation (ASCT) in a new drug era in China.Methods:This multicenter retrospective cohort study enrolled patients with newly diagnosed MM from three centers in China (Beijing Chao-Yang Hospital, Capital Medical University; the First Affiliated Hospital, Sun Yat-Sen University, and the Second Affiliated Hospital of Naval Medical University) from June 2008 to June 2018. A total of 401 newly diagnosed patients with MM who were candidates for ASCT were enrolled in this cohort, all received proteasome inhibitor and/or immunomodulator-based induction chemotherapy followed by ASCT. Baseline and follow-up data were collected. The patients were regrouped using R2-ISS. Progression-free survival (PFS) and overall survival (OS) were analyzed. The Kaplan-Meier method was used to analyze the survival curve and two survival curves were compared using the log-rank test. Cox regression analysis were performed to analyze the relationship between risk factors and survival.Results:The median age of the patients was 53 years (range 25-69 years) and 59.5% (240 cases) were men. Newly diagnosed patients with renal impairment accounted for 11.5% (46 cases). According to Revised-International Staging System (R-ISS), 74 patients (18.5 %) were diagnosed with stage Ⅰ, 259 patients (64.6%) with stage Ⅱ, and 68 patients (17.0%) with stage Ⅲ. According to the R2-ISS, the distribution of patients in each group was as follows: 50 patients (12.5%) in stage Ⅰ, 95 patients (23.7%) in stage Ⅱ, 206 patients (51.4%) in stage Ⅲ, and 50 patients (12.5%) in stage Ⅳ. The median follow-up time was 35.9 months (range, 6-119 months). According to the R2-ISS stage, the median PFS in each group was: 75.3 months for stage Ⅰ; 62.0 months for stage Ⅱ, 39.2 months for stage Ⅲ, and 30.3 months for stage Ⅳ; and the median OS was not reached, 86.6 months, 71.6 months, and 38.5 months, respectively. There were statistically significant differences in PFS and OS between different groups (both P<0.001). Multivariate Cox regression analysis showed that stages Ⅲ and Ⅳ of the R2-ISS were independent prognostic factors for PFS ( HR=2.37, 95% CI 1.30-4.30; HR=4.50, 95% CI 2.35-9.01) and OS ( HR=4.20, 95% CI 1.50-11.80; HR=9.53, 95% CI 3.21-28.29). Conclusions:The R2-ISS has significant predictive value for PFS and OS for transplant-eligible patients with MM in the new drug era. However, the universality of the R2-ISS still needs to be further verified in different populations.

Objective To investigate the risk factors of microcirculation obstruction(MVO)after reperfusion in patients with acute myocardial infarction(AMI).Methods Forty-one patients with AMI who received treatment with myocardial reperfusion were retrospectively selected.Cardiac magnetic resonance(CMR)was used to determine whether the patients had MVO.The patients were divided into MVO and non-MVO groups.The basic data,laboratory examination and CMR parameters of patients were collected and compared between the groups,and the risk factors related to MVO were screened out by logistic regression analysis.Results Delayed myocardial enhancement was observed in all 41 patients,among which 11 cases(26.8%)were with MVO.A total of 206 delayed myocardial enhancement segments were observed,of which 77 segments combined with MVO and 129 segments without MVO.AMI patients with MVO had a higher rate of transmural myocardial infarction,greater infarct volume,left ventricular myocardial mass(LVMM)and edema degree,as well as lower ejection fraction of left and right ventricles(P<0.05).Multivariate logistic regression analysis indicated that infarct volume[odds ratio(OR)=1.116,95%confidence interval(CI)1.017-1.224,P=0.020]was an independent risk factor for MVO after AMI reperfusion.Conclusion Infarct volume is an independent risk factor for MVO after AMI reperfusion,and MVO is associated with left and right ventricular function impairment.

Based on the principle of'treating disease and seeking the root cause',Professor FU Wen-Bin proposed'treating radiation encephalopathy(REP)from yang',pointing out that the main pathogenesis of REP is yang qi deficiency,brain spirit dystrophy,phlegm and blood stasis blocking orifices.Using'supplementing yang and unblocking yang simultaneously','treating spirit from heart and gallbladder',combined with the method of regulating spirit and unblocking orifices at acupoints of governor vessol and conception vessel,and using the integrated acupuncture mode of'firstly applying needling,secondly using moxibustion,thirdly focusing on consolidation'to play the role of supporting yang and treating spirit can effectively relieve symptoms and delay the development of the disease.

Purpose::Head injury criterion (HIC) companied by a rotation-based metric was widely believed to be helpful for head injury prediction in road traffic accidents. Recently, the Euro-New Car Assessment Program utilized a newly developed metric called diffuse axonal multi-axis general evaluation (DAMAGE) to explain test device for human occupant restraint (THOR) head injury, which demonstrated excellent ability in capturing concussions and diffuse axonal injuries. However, there is still a lack of comprehensive understanding regarding the effectiveness of using DAMAGE for Hybrid III 50th percentile male dummy (H50th) head injury assessment. The objective of this study is to determine whether the DAMAGE could capture the risk of H50th brain injury during small overlap barrier tests.Methods::To achieve this objective, a total of 24 vehicle crash loading curves were collected as input data for the multi-body simulation. Two commercially available mathematical dynamic models, namely H50th and THOR, were utilized to investigate the differences in head injury response. Subsequently, a decision method known as simple additive weighting was employed to establish a comprehensive brain injury metric by incorporating the weighted HIC and either DAMAGE or brain injury criterion. Furthermore, 35 sets of vehicle crash test data were used to analyze these brain injury metrics.Results::The rotational displacement of the THOR head is significantly greater than that of the H50th head. The maximum linear and rotational head accelerations experienced by H50th and THOR models were (544.6 ± 341.7) m/s 2, (2468.2 ± 1309.4) rad/s 2 and (715.2 ± 332.8) m/s 2, (3778.7 ± 1660.6) rad/s 2, respectively. Under the same loading condition during small overlap barrier (SOB) tests, THOR exhibits a higher risk of head injury compared to the H50th model. It was observed that the overall head injury response during the small overlap left test condition is greater than that during the small overlap right test. Additionally, an equation was formulated to establish the necessary relationship between the DAMAGE values of THOR and H50th. Conclusion::If H50th rather than THOR is employed as an evaluation tool in SOB crash tests, newly designed vehicles are more likely to achieve superior performance scores. According to the current injury curve for DAMAGE and brain injury criterion, it is highly recommended that HIC along with DAMAGE was prioritized for brain injury assessment in SOB tests.

Intramedullary needle(IMN)has the advantages of high healing rate and low incidence of complications in treatment of tibial fracture,and has become one of the most commonly used fixation methods for the treatment of tibial fracture.However,due to the patient's own factors,fracture location and fracture type,infection and surgical treatment,bone nonunion after IMN still occurs in clinic.Bone nonunion leads to the increase of medical cost and prolonged the hospitalization time of patients,which causes great pain to patients,and also brings great challenges to the treatment of orthopedic surgeons.Therefore,this paper reviews the influencing factors of bone nonunion after IMN for tibial fracture,in order to provide reference for clinical treatment.

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.

Objective: To investigate the etiology, complications, and prognostic factors of stage 5 chronic kidney disease (CKD5) in children. Methods: A case series study was conducted to retrospectively analyze the general situation, clinical manifestations, laboratory tests, genetic testing, and follow-up data (until October 2022) of 174 children with CKD5 who were diagnosed and hospitalized at the Children's Hospital of Chongqing Medical University from April 2012 to April 2021. The characteristics of complications in the children were compared based on age, gender, and etiology. Based on the presence or absence of left ventricular hypertrophy (LVH), patients were divided into LVH group and non LVH group for analyzing the influencing factors of cardiovascular disease. Patients were also divided into death group and survival group, peritoneal dialysis group and hemodialysis group based on the follow-up data for analyzing the prognostic factors. The chi-square test, independent sample t-test, Fisher exact probability test, Mann-Whitney U test and Kruskal Wallis test were used to analyze data among different groups. Multivariate Logistic regression analysis was used to identify the prognostic factors. Results: A total of 174 children with CKD5 were enrolled in the study (96 boys and 78 girls), aged 11.2 (8.2, 13.0) years. Congenital kidney and urinary tract malformations (CAKUT) were the most common causes of the CKD5 (84 cases, 48.3%), followed by glomerular diseases (83 cases, 47.7%), and among which 28 cases (16.1%) were hereditary glomerular diseases. The common complications of CKD5 included anemia (98.2%, 165/168), mineral and bone disorder in chronic kidney disease (CKD-MBD) (97.7%, 170/174), lipid metabolism disorders (87.5%, 63/72), hypertension (81.4%, 127/156) and LVH (57.6%,57/99). The incidences of hypertension in primary glomerular disease were higher than that in CAKUT(93.8%(30/32) vs.73.7%(56/76),χ²=5.59,P<0.05). The incidences of hypertension in secondary glomerular disease were higher than that in CAKUT and that in hereditary kidney disease (100.0%(20/20) vs. 73.7%(56/76), 68.2%(15/22), both P<0.05). The incidence of hypocalcemia in CAKUT, primary glomerular disease, and hereditary kidney disease was higher than that in secondary glomerular disease (82.1%(69/84), 88.2%(30/34), 89.3%(25/28) vs. 47.6%(10/21), χ²=10.21, 10.75, 10.80, all P=0.001); the incidence of secondary hyperparathyroidism in women was higher than that in men (80.0%(64/80) vs. 95.0%(57/60), χ²=6.58, P=0.010). The incidence of LVH in children aged 6-<12 was higher than that in children aged 12-18 (73.5%(25/34) vs. 43.1%(22/51), χ²=7.62, P=0.006). Among 113 follow-up children, the mortality rate was 39.8% (45/113). Compared to the survival group, the children in the death group had lower hemoglobin, higher blood pressure, lower albumin, lower alkaline phosphatase and higher left ventricular mass index ((67±19) vs. (75±20) g/L, 142 (126, 154) vs. 128(113, 145) mmHg(1 mmHg=0.133 kPa), (91±21) vs. (82±22) mmHg, 32 (26, 41) vs. 40 (31, 43) g/L, 151 (82, 214) vs. 215 (129, 37) U/L, 48 (38, 66) vs. 38(32, 50) g/m^2.7,t=2.03, Z=2.89, t=2.70, Z=2.49, 2.79, 2.29,all P<0.05), but no independent risk factors were identified (all P>0.05). The peritoneal dialysis group had better alleviation for anemia, low calcium, and high phosphorus than the hemodialysis group ((87±22) vs. (72±16) g/L, (1.9±0.5) vs. (1.7±0.4) mmol/L, (2.2±0.7) vs. (2.8±0.9) mmol/L, t=2.92, 2.29, 2.82, all P<0.05), and the survival rate of the peritoneal dialysis group was significantly higher than that of the hemodialysis group (77.8% (28/36) vs. 48.4% (30/62), χ²=8.14, P=0.004). Conclusions: CAKUT is the most common etiology in children with CKD 5, and anemia is the most common complication. The incidence of complications in children with CKD 5 varies with age, gender and etiology. Anemia, hypertension, hypoalbuminemia, reduced alkaline phosphatase and elevated LVMI may be the prognostic factors in children with CKD5. Peritoneal dialysis may be more beneficial for improving the long-term survival rate.

Objective:To study the clinical manifestations and treatment of neonatal testicular torsion (NTT) and to summarize the experience of diagnosis and treatment.Methods:The clinical data of the patients with NTT admitted to the Department of Pediatric Urology in Guangzhou Women and Children's Medical Center from January 2015 to January 2021 were analyzed retrospectively. The data included demographic information, testicular torsion duration, clinical presentation, ultrasonography findings, surgical procedures, pathological results, follow-ups, and prognosis.Results:A total of 17 cases were enrolled in this study, and the median age was 5.2 d, ranging from 1 d to 17 d; the weight ranging from 2 800 g to 4 000 g. 11 cases of left testicular torsion and 6 cases of right testicular torsion. The median time from onset to medical attention was 3.8 d, ranging from 10 h to 15 d. The first manifestations being reported were scrotal swelling, color change, or painless mass. Emergency ultrasound revealed that the blood flow signal in the testis was significantly reduced or disappeared, and heterogeneous mass echoes were detected in the scrotum. Surgical exploration was performed in all 17 cases and confirmed to be testicular torsion. There were 15 cases of extravaginal torsion and 2 cases of intravaginal torsion. There were 6 cases of clockwise torsion and 11 cases of anticlockwise torsion. The average degree of twisted testis was 450.8°, ranging from 270° to 720°. The rate of orchiectomy was 88.2% (15/17). All patients were followed up for a minimum of 1 year postoperatively. None of the patients experienced postoperative bleeding or infection at the scrotal incision site. There were no instances of recurrent testicular torsion, and the contralateral testicles showed no abnormalities. In 2 cases where the affected testicle was preserved, ultrasound reevaluation at 6 months postoperatively revealed atrophy of the affected testicle.Conclusions:NTT is rare in clinics and lacks specificity, with a high rate of testis loss. When the newborns exhibit scrotal swelling, color change, or other abnormalities, testicular torsion cannot be ruled out, and early surgical exploration is required.

Professor FU Wen-bin, based on the concept of the "yang-oriented approach", identifies "yang deficiency with excess yin" as the underlying pathological mechanism of "five delays and five weaknesses" in children. He recommends a treatment model that included acupuncture, moxibustion, and rehabilitation, integrating various therapeutic methods of acupuncture, refined moxibustion, and auricular point sticking. Specific acupoints along the conception vessel, governor vessel, and bladder meridian, as well as related acupoints with tonifying effects on spleen and kidney, are selected to achieve the therapeutic goal of "promoting yang and nourishing yang simultaneously".
