BACKGROUND:Traditional surgery for lumbar disc herniation involves extensive excision of tissue surrounding the nerve for decompression and removal of protruding lumbar intervertebral discs,which poses various risks and complications such as nerve damage causing paralysis,lumbar instability,herniation recurrence,intervertebral space infection,and adjacent vertebral diseases. OBJECTIVE:To propose the symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous technique for lumbar spine symmetrically decompression,showing the induced resorption of herniated nucleus pulpous phenomenon and early clinical efficacy,and then analyze its decompression mechanism. METHODS:214 patients with lumbar disc herniation at Department of Orthopedics,First Affiliated Hospital of Zhengzhou University from March 2021 to May 2023 were enrolled in this study.Among them,81 patients received conservative treatment as the control group,and 133 patients received symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous treatment as the trial group.Before surgery,immediately after surgery(7-14 days),and early after surgery(over 1 year),MRI images were used to measure the volume changes of lumbar disc herniation.CT images were used to measure the posterior displacement distance of the lumbar spinous process ligament complex,as well as the width and height of the lateral recess.Japanese Orthopaedic Association scores were used to evaluate the patient's neurological function recovery. RESULTS AND CONCLUSION:(1)Control group:81 patients with lumbar disc herniation were treated conservatively,with a total of 171 herniated lumbar discs.The average follow-up time was(22.7±23.1)months.The first and second MRI measurements of 171 herniated lumbar discs showed herniated lumbar disc volumes of(551.6±257.9)mm3 and(792.2±330.4)mm3,respectively,with an average volume increase rate of(53.2±44.4)%,showing statistically significant differences(P<0.001).Out of 171 herniated lumbar discs,4 experienced natural shrinkage,with an absorption ratio of 2.3%(4/171)and an absorption rate of(24.5±9.9)%.(2)Trial group:133 patients with lumbar disc herniation had a total of 285 herniated lumbar discs.(1)Immediately after surgery:All patients were followed up immediately after surgery.229 out of 285 herniated lumbar discs experienced retraction,with an absorption ratio of 80.3%(229/285)and an average absorption rate of(21.5±20.9)%,with significant and complete absorption accounting for 6.5%.There were a total of 70 herniated lumbar discs in the upper lumbar spine,with an absorption ratio of 85.7%(60/70),an average absorption rate of(23.1±19.5)%,and a maximum absorption rate of 86.6%.There were 215 herniated lumbar discs in the lower lumbar spine,with an absorption ratio of 78.6%(169/215),an average absorption rate of(21.0±21.3)%,and a maximum absorption rate of 83.2%.Significant and complete absorption of the upper and lower lumbar vertebrae accounted for 5.7%and 6.5%,respectively,with no statistically significant difference(P>0.05).The average distance of posterior displacement of the spinous process ligament complex immediately after surgery was(5.2±2.8)mm.There were no significant differences in the width and height of the left and right lateral recess before and immediately after surgery(P>0.05).The Japanese Orthopaedic Association score immediately after surgery increased from(10.1±3.4)before surgery to(17.0±4.8),and the immediate effective rate after surgery reached 95.6%.(2)Early postoperative period:Among them,46 patients completed the early postoperative follow-up.There were 101 herniated lumbar discs,with an absorption ratio of 94%(95/101)and an average absorption rate of(36.9±23.7)%.Significant and complete absorption accounted for 30.6%,with a maximum absorption rate of 100%.Out of 101 herniated lumbar discs,3 remained unchanged in volume,with a volume invariance rate of 2.97%(3/101).Out of 101 herniated lumbar discs,3 had an increased volume of herniated lumbar discs,with an increase ratio of 2.97%(3/101)and an increase rate of(18.5±18.4)%.The Japanese Orthopaedic Association score increased from preoperative(9.3±5.1)to(23.5±4.0),with an excellent and good rate of 93.4%.(3)The early postoperative lumbar disc herniation absorption ratios of the control group and trial group were 2.3%and 85.9%,respectively,with statistically significant differences(P<0.001).(4)Complications:There were two cases of incision exudation and delayed healing in the trial group.After conservative treatment such as dressing change,no nerve injury or death occurred in the incision healing,and no cases underwent a second surgery.(5)It is concluded that symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous is a new method for treating lumbar disc herniation that can avoid extensive excision of the"ring"nerve and achieve satisfactory early clinical efficacy.It does not damage the lumbar facet joints or alter the basic anatomical structure of the lateral recess,fully preserves the herniated lumbar discs,and can induce significant or even complete induced resorption of herniated nucleus pulpous.Symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous provides a new basis and method for the clinical treatment of lumbar disc herniation.

OBJECTIVES: To evaluate the feasibility, efficacy and safety of Sentinel cerebral embolic protection device (CEPD) during transcatheter aortic valve replacement (TAVR). This study is a subgroup analysis of the China Moderate to Severe Valvular Heart Disease Registry, which has been registered at the Chinese Clinical Trial Registry (ChiCTR2300075006). METHODS: Patients undergoing TAVR with the Sentinel CEPD from October 2023 to September 2024 were retrospectively enrolled. A total of 80 patients were included, with a median age of 72 (68, 76) years, including 52 males (65.0%) and 28 females (35.0%); 62 patients (77.5%) with tricuspid valves, and 18 patients (22.5%) with bicuspid valves; 34 patients (42.5%) with type Ⅰ aortic arch, 24 patients (30.0%) with type Ⅱ aortic arch, 12 patients (15.0%) with type Ⅲ aortic arch, and 10 patients (12.5%) with bovine-type aortic arch. Clinical data of the patients were summarized and analyzed. The primary endpoints were success rate of Sentinel CEPD implantation, as well as all-cause death, symptomatic stroke, transient ischemic attack, and Sentinel CEPD access vessel complications during hospitalization and within 30 days postoperatively. RESULTS: In the 80 patients, self-expanding valves were used in 68 cases (85.0%) and balloon-expandable valves in 12 cases (15.0%). Seventy-nine patients (98.8%) successfully underwent TAVR with Sentinel CEPD deployment. Macroscopically visible debris was captured in 92.5% (74/80) by filters of Sentinel CEPD. Although the procedure time for Sentinel CEPD placement was slightly longer in patients with bovine-type aortic arch, there was no statistically significant difference in deployment time among different aortic arch types (P>0.05). During hospitalization and within 30 days postoperatively, only one case of transient ischemic attack occurred, and there was no all-cause mortality, symptomatic stroke, or access-site vascular complications related to the Sentinel CEPD observed. CONCLUSIONS The Sentinel CEPD demonstrates high feasibility across aortic arch types, potential efficacy in embolic capture, and excellent safety in TAVR.

Objective To systematically review the efficacy and safety of different oral Chinese patent medicines combined with conventional western medicines in the therapy of lumbar disc herniation(LDH).Methods PubMed,Embase,Cochrane Library,Medline,CNKI,WanFang data,VIP and SinoMed databases were electronically searched to collect randomized clinical trials(RCTs)on oral Chinese patent medicines combined with conventional western medicines in the treatment of LDH from the inception to April 10,2023.Two reviewers independently screened the literature,extracted data,and evaluated the risk of bias of included studies.Network Meta-analysis was then performed by Stata 17.0 and RevMan 5.4 softwares.Results A total of 26 RCTs were included,involving 16 Chinese patent medicines with a total sample size of 2 448 cases.The network Meta-analysis results showed that 13 Chinese patent medicines combined with conventional western medicines had better effects than conventional western medicines alone.Among them,in terms of a better VAS score,the top three interventions were Jingyaokang capsules+conventional western medicine＞Yaobitong capsules+conventional western medicine＞Huoxue Zhitong capsules+conventional western medicine;in terms of a better Japanese Orthopaedic Associationl(JOA)score,the top three interventions were Qufeng Zhitong capsules+conventional western medicine＞Yaobitong capsules+conventional western medicine＞Luchuan Huoluo capsules+conventional western medicine;in terms of the clinical effective rate,the top three interventions were Luchuan Huoluo capsules+conventional western medicine＞Xianling Gubao capsules+conventional western medicine＞Tongzhi Surunjiang capsules+conventional western medicine;in terms of safety,no serious adverse drug reactions occurred in all studies,and the overall incidence of adverse drug reactions in the oral Chinese patent medicines combined with conventional western medicines group was lower than that in the conventional western medicines group.Conclusion The combination of oral Chinese patent medicines and conventional western medicines has been shown to improve the clinical efficacy of LDH.Among these,Yaobitong capsules stand out for its ability to reduce VAS score,improve JOA score ranking,and increase the effective rate.Due to limited quality and quantity of the included studies,more high-quality studies are required to verify the above conclusions.

Transcatheter aortic valve replacement(TAVR)is one of the most important guideline-recommended procedures for severe symptomatic aortic stenosis.Acute cerebral infarction is a serious complication after TAVR,with a high incidence rate and may significantly affect patient prognosis and quality of life.Thrombolysis and mechanical thrombectomy are standard treatments for acute cerebral infarction recommended by guidelines,but evidence of their efficacy and safety in patients undergoing TAVR is limited.We report a patient with acute cerebral infarction after TAVR,who were treated with emergency cerebral angiography and successful transcatheter thrombectomy.

Objectives:To explore the effects of interatrial shunt on cardiac function and clinical prognosis of patients with heart failure with reduced ejection fraction(HFrEF). Methods:This study was a prospective single-arm study.From December 2021 to December 2022,15 consecutive patients with HFrEF from Beijing Anzhen Hospital were enrolled in this study.Interatrial shunt was performed with a D-Shant atrial shunt device.Right heart catheterization was performed before and immediately after device implantation,pulmonary capillary wedge pressure(PCWP),mean right atrial pressure(RAP),interatrial gradient pressure,mean pulmonary artery pressure,total pulmonary resistance(TPR),pulmonary vascular resistance(PVR),cardiac index(CI),and pulmonary/systemic blood flow ratio(Qp/Qs)were measured.Patients were followed-up for 12 months after procedure,changes in cardiac structure and function were evaluated by echocardiography.NYHA classification,6-minute walking distance(6MWD),and Kansas City cardiomyopathy questionnaire(KCCQ)were observed.All-cause mortality and rehospitalization for heart failure served as clinical endpoints. Results:Interatrial shunt procedure was successful in all patients.Compared with preoperative value,PCWP,interatrial gradient pressure,mean pulmonary artery pressure,and TPR were significantly decreased,while Qp/Qs was significantly increased immediately after procedure(all P<0.01).There were no significant changes in RAP,PVR,and CI post procedure(all P>0.05).There were no significant differences in shunt size,shunt velocity,and shunt pressure difference between postoperative immediately and at 12-months follow-up(all P>0.05).At 12 months,left ventricular ejection fraction was significantly higher than baseline level(P<0.05),and there were no significant changes in right atrial diameter and right ventricular fractional area change(both P>0.05).Compared with preoperative status,NYHA classification was improved,KCCQ score was increased,and the number of patients with 6MWD>450 m was increased at 12 months(all P<0.05).N-terminal pro-B-type natriuretic peptide value was significantly decreased at 12 months(P<0.05).No patient died during the 12-months follow-up period,and there were no device-related adverse events.Two patients experienced hospital readmission for heart failure. Conclusions:Implantation of interatrial shunt device could effectively improve hemodynamic parameters in patients with HFrEF and is related to significantly improved cardiac function at 12-months follow-up.

OBJECTIVE To improve the quality standard of Yi medicine Gynura japonica， and to evaluate its quality. METHODS Using 15 batches of G. japonica from different producing areas as samples， the contents of water， total ash， acid- insoluble ash and water-soluble extract were determined according to the method stated in part Ⅳ of Chinese Pharmacopoeia （2020 edition）. The contents of total alkaloid （calculated by senecionine） was determined by UV spectrophotometry. The contents of senecionine and seneciphylline were determined by HPLC. Using above 7 indexes as evaluation indexes， cluster heat map analysis， principal component analysis （PCA） and entropy weight approximation ideal ranking （TOPSIS） were used to evaluate the quality of medicinal material comprehensively. RESULTS Among 15 batches of G. japonica， the moisture contents were 8.88%-12.60%， the total ash contents were 4.43%-11.02%， the acid-insoluble ash contents were 0.56%-3.45%， the water-soluble extract contents were 21.71%-53.91%， the total alkaloid contents （calculated by senecionine） were 0.15%-0.39%， and the contents of senecionine and seneciphylline were 0.01% -0.05% and 0.01%-0.06% respectively. According to the results of various indicators， it was preliminarily proposed that the water content in the sample of G. japonica should not exceed 13.00%， the total ash content should not exceed 11.50%， the acid-insoluble ash content should not exceed 3.70%， the water-soluble extract should not be less than 20.70%， the total alkaloid content should not be less than 0.15%， the contents of senecionine and seneciphylline should not be less than 0.01% both. The results of cluster heat map analysis showed that the 15 batches of samples could be divided into four categories； the results of PCA and TOPSIS showed that the samples with high-quality ranking were jsq-2， jsq-5， jsq-6 and jsq-10， and the samples with low-quality ranking were jsq-4， jsq-13 and jsq-14. CONCLUSIONS In this study， the quantitative analysis method of total alkaloids （calculated by senecionine）， senecionine and seneciphylline in G. japonica is established， and the limits of each index are preliminarily determined. Among 15 batches of samples， the qualities of medicinal material collected from Linza Village of Ganluo County of Liangshan Yi Autonomous Prefecture， Machangping Village of Luojishan Town of Puge County of Liangshan Yi Autonomous Prefecture and other places are better.

As an important complementary form of decoction pieces of traditional Chinese medicine（TCM）， TCM dispensing granules has the advantages of being free of decoction， easy to take， easy to carry and easy to be dispensed， which greatly improves the capacity of emergency services of TCM and is more in line with the needs of modern society. With the end of the pilot project of TCM dispensing granules， the market has been fully liberalized， the competition has been intensified， and it is in the transition period of switching between the new standard and the old one， and there are some problems such as the shortage of varieties， the change of specifications and the difference of quality， and the production enterprises are facing new opportunities and challenges. Based on this， the authors intend to systematically sort out the policies and regulations， enterprise layout and standard formulation since the pilot of TCM dispensing granules. In view of the problems in the post-pilot stage and from the perspective of survival and development of enterprises， it is suggested that enterprises should establish a quality control system for the whole industry chain of TCM dispensing granules to reduce process costs and increase enterprise competitiveness， further increase the investment in scientific research， overcome the key technical problems of difficult varieties， actively and orderly promote the research of national standards， in order to ensure the integrity of clinical formula varieties， and establish and improve the efficacy evaluation mechanism of TCM dispensing granules， build a consistency evaluation system between TCM dispensing granules and decoction pieces. Government departments should strengthen the guidance， fully mobilize the enthusiasm of scientific research institutions， enterprises and hospitals， and explore the establishment of "government-industry-study-research-application" mode to promote the development of TCM dispensing granule industry.

Primary central nervous system lymphoma (PCNSL) is a rare and aggressive non-Hodgkin’s lymphoma that affects the brain, eyes, cerebrospinal fluid, or spinal cord without systemic involvement. The outcome of patients with PCNSL is worse compared to patients with systemic diffuse large B-cell lymphoma. Given potential mortality associated with severe immune effector cell-associated neurotoxicity syndrome (ICANS), patients with PCNSL have been excluded from most clinical trials involving chimeric antigen receptor T-cell (CAR-T) therapy initially. Here, we report for the first time to apply decitabine-primed tandem CD19/CD22 dual-targeted CAR-T therapy with programmed cell death-1 (PD-1) and Bruton’s tyrosine kinase (BTK) inhibitors maintenance in one patient with multiline-resistant refractory PCNSL and the patient has maintained complete remission (CR) for a 35-month follow-up period. This case represents the first successful treatment of multiline resistant refractory PCNSL with long-term CR and without inducing ICANS under tandem CD19/CD22 bispecific CAR-T therapy followed by maintenance therapy with PD-1 and BTK inhibitors. This study shows tremendous potential in the treatment of PCNSL and offers a look toward ongoing clinical studies.

BACKGROUND: Evidence on the relations of the American Heart Association's ideal cardiovascular health (ICH) with mortality in Asians is sparse, and the interaction between behavioral and medical metrics remained unclear. We aimed to fill the gaps. METHODS: A total of 198,164 participants without cancer and cardiovascular disease (CVD) were included from the China Kadoorie Biobank study (2004-2018), Dongfeng-Tongji cohort (2008-2018), and Kailuan study (2006-2019). Four behaviors (i.e., smoking, physical activity, diet, body mass index) and three medical factors (i.e., blood pressure, blood glucose, and blood lipid) were classified into poor, intermediate, and ideal levels (0, 1, and 2 points), which constituted 8-point behavioral, 6-point medical, and 14-point ICH scores. Results of Cox regression from three cohorts were pooled using random-effects models of meta-analysis. RESULTS: During about 2 million person-years, 20,176 deaths were recorded. After controlling for demographic characteristics and alcohol drinking, hazard ratios (95% confidence intervals) comparing ICH scores of 10-14 vs. 0-6 were 0.52 (0.41-0.67), 0.44 (0.37-0.53), 0.54 (0.45-0.66), and 0.86 (0.64-1.14) for all-cause, CVD, respiratory, and cancer mortality. A higher behavioral or medical score was independently associated with lower all-cause and CVD mortality among the total population and populations with different levels of behavioral or medical health equally, and no interaction was observed. CONCLUSIONS ICH was associated with lower all-cause, CVD, and respiratory mortality among Chinese adults. Both behavioral and medical health should be improved to prevent premature deaths.

Objective:To investigate the effect of the distance of the circumferential resection margin (CRM) on postoperative recurrence after laparoscopic radical resection of colon cancer.Methods:The clinical data of 83 patients who underwent laparoscopic radical resection of colon cancer in Yiwu Central Hospital from January 2020 to January 2022 were retrospectively included. They were divided into recurrent group (16 cases) and non-recurrent group (67 cases) according to the recurrence within 1 year after operation. The clinical data, postoperative CRM distance and laboratory indicators of the two groups were collected to analyze the influence of CRM distance on postoperative recurrence after laparoscopic radical resection of colon cancer.Results:The proportion of patients treated with postoperative chemotherapy, and postoperative CRM distance in the recurrent group were lower than those in the non-recurrent group: 9/16 vs. 83.58 % (56/67), (0.85 ± 0.23) mm vs. (1.64 ± 0.76) mm. The levels of CEA and CA19-9 at admission were higher than those in the non-recurrent group: (156.74 ± 11.58) μg/L vs. (149.96 ± 10.26) μg/L, (15.63 ± 2.77) kU/L vs. (14.04 ± 2.35) kU/L, and the differences were statistically significant ( P<0.05). Point binary correlation analysis showed that there was a negative correlation between CRM distance and postoperative recurrence after laparoscopic radical resection of colon cancer ( r = - 0.412, P<0.01). Multivariate Logistic regression analysis showed that the long distance of CRM was the protective factor of recurrence after laparoscopic radical resection of colon cancer ( OR<1, P<0.05). The results of the receiver operating characteristic (ROC) curve showed that the area under the curve (AUC) of the CRM distance to predict the recurrence after laparoscopic radical resection of colon cancer was 0.833>0.7, and the predictive value was good. When the optimal threshold was 1.080 mm, the ideal sensitivity and specificity could be obtained 87.50% and 81.00%. Conclusions:The shorter the CRM distance after laparoscopic radical resection of colon cancer, the higher the risk of recurrence. The CRM distance can be used as a predictor of recurrence after laparoscopic radical resection of colon cancer.
