As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

ObjectiveTo observe the clinical efficacy and safety of traditional Chinese medicine （TCM） triple therapy in the treatment of spontaneous bacterial peritonitis （SBP） with damp-heat stagnation and toxin-blood stasis syndrome in liver cirrhosis patients， and to explore its potential mechanisms of action. MethodsEighty-six patients were randomly divided into the experimental group and the control group， with 43 patients in each group. Both groups received standard western medicine treatment， while the experimental group additionally received TCM triple therapy， including oral Qingre Liangxue Jiedu Decoction （清热凉血解毒汤）， retention enema with Dachengi Decoction （大承气汤）， and abdominal application of Qingre Zhitong Lishui Fomulation （清热止痛利水方） with lotus leaf. Both groups were treated for 2 weeks. Before and after treatment， various indicators were measured， such as TCM syndrome scores， ascites volume measured by abdominal ultrasound， liver function indicators including total bilirubin （TBIL）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， and albumin （ALB）， infection markers， including neutrophil percentage （NEUT%）， C-reactive protein （CRP）， and procalcitonin （PCT）， inflammatory factors， such as tumor necrosis factor-alpha （TNF-ɑ）， interleukin-6 （IL-6）， and interleukin-10 （IL-10）， intestinal mucosal barrier function markers， including endotoxin （ET）， diamine oxidase （DAO）， D-lactic acid （D-Lac）， occludin， and zonula occludens-1 （ZO-1）， and peritoneal polymorphonuclear （PMN） cell counts at 72 hours post-treatment. ResultsA total of 82 patients were included in the final analysis， with 41 patients in each group. The total effective rate for TCM syndrome in the experimental group was 92.68% （38/41）， which was significantly higher than the 80.49% （33/41） in the control group （P＜0.05）. Compared with pre-treatment values， both groups showed significant reductions in TCM syndrome scores， ascites volume， TBIL， ALT， AST， NEUT%， CRP， PCT， TNF-α， IL-6， ET， DAO， D-Lac， Occludin， and ZO-1， with an increase in IL-10 levels and a decrease in PMN count in ascites 72 hours post-treatment （P＜0.05）. Furthermore， the experimental group outperformed the control group in all the above indicators after treatment （P＜0.05）. The disappearance time of fever and abdominal pain was shorter in the experimental group than in the control group （P＜0.01）. There were no significant changes in routine urine and stool tests， renal function， electrolytes， or electrocardiogram in either group compared with pre-treatment values. ConclusionTCM triple therapy in addition to western medicine routine treatment could significantly improves clinical symptoms in patients with liver cirrhosis and SBP with damp-heat stagnation and toxin-blood stasis syndrome， alleviates liver inflammation， improves liver function， accelerates the resolution of ascites， and increases clinical efficacy. The potential mechanism may be related to the regulation of the inflammatory response and the promotion of intestinal mucosal barrier repair.

Objective To explore the effect of Sangxing Zhike Formula in rats with cough vari-ant asthma(CVA)and its possible mechanism based on the cyclic adenosine monophosphate(cAMP)/cystic fibrosis transmembrane conductance regulator(CFTR)pathway.Methods SD rats were randomly divided into control group,model group,dexamethasone group(0.5 mg/kg)and low-,medium-,high-dose Sangxing Zhike Formula groups(9.6,19.2 and 38.4 g/kg)using a ran-dom number table method,with 9 rats in each group.Except for the control group,CVA rat models were established in the other groups.Rats in each group were administered the drug by gavage once a day for 14 consecutive days.The general conditions of rats in each group were observed.Enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of interleukin-1β(IL-1β)and interleukin-18(IL-18)in rat serum.Hematoxylin-eosin(HE)staining and periodic acid-Schiff(PAS)staining were used to observe the pathological changes in rat lung and bronchial tissues,and the acid-base balance of airway surface liquid(ASL)was measured.Western blot and real-time fluorescence quantitative polymerase chain reaction(RT-qPCR)were used to detect the expression levels of pro-tein kinase A(PKA),CFTR protein and their mRNA in lung tissues of rats.Results Compared with the control group,rats in the model group showed listlessness,dull fur,slow weight gain,a significantly expanded area of alveolar septal consolidation,and a large number of inflammatory cell infiltrations around the bronchi.Compared with the model group,rats in each intervention group had better general conditions and reduced inflammatory infiltrations in lung tissues and bronchial lu-mens.Compared with the control group,the serum levels of IL-1 β and IL-18 in the model group were increased,and the pH values of ASL in the model group,low-dose Sangxing Zhike Formula group,medium-dose Sangxing Zhike Formula group,and high-dose Sangxing Zhike Formula group were all decreased,with statistically significant differences(P＜0.05).Compared with the model group,the serum levels of IL-1β and IL-18 in each intervention group were decreased,and the pH values of ASL in the dexamethasone group,medium-dose Sangxing Zhike Formula group,and high-dose Sangxing Zhike Formula group were increased,with statistically significant differences(P＜0.05).Compared with the control group,the expressions of PKA protein and PKA mRNA in the model group,low-dose Sangxing Zhike Formula group,and medium-dose Sangxing Zhike Formula group were all decreased,and the expressions of CFTR protein and CFTR mRNA in the model group and each intervention group were all decreased,with statistically significant differences(P＜0.05).Compared with the model group,the expressions of PKA protein and PKA mRNA in the dexametha-sone group and high-dose Sangxing Zhike Formula group were increased,and the expressions of CFTR protein and CFTR mRNA in the high-dose Sangxing Zhike Formula group were increased,with statistically significant differences(P＜0.05).Conclusion Sangxing Zhike Formula can im-prove the general conditions of CVA rats,regulate the acid-base balance of ASL,reduce airway in-flammatory cell infiltration andairway remodeling,and decrease the levels of inflammatory factors IL-1β and IL-18.Its mechanism may be related to the cAMP/CFTR pathway.

Objective: To investigate the therapeutic effect of bone marrow mesenchymal stem cells ( BMSCs) mod- ified by bone morphogenetic protein ( BMP) -2 gene combined with nano-hydroxyapatite ( nHA) / polyamide 66 ( PA66) on femoral nonunion in rats． Methods : Rat BMSCs were isolated and divided into the stent + BMSCs group，stent + BMSCs + rhBMP-2 group，and stent + BMSCs + Ad-BMP-2 group; human recombinant BMP-2 ( rh- BMP-2) or adenovirus-infected BMP-2 ( Ad-BMP-2) vector was transfected into BMSCs and loaded onto nHA / PA66 stent materials．Flow cytometry was used to detect that BMSCs expressed specific surface markers．Cell pro- liferation was detected by MTT assay，related bioactive factors［platelet-derived growth factor ( PDGF) ，transfor- ming growth factor-β ( TGF-β) ，vascular endothelial growth factor ( VEGF) ，fibroblast growth factor ( FGF) ，os- teocalcin ( OCN) ，osteonectin ( ON) ］were detected by ELISA，alkaline phosphatase ( ALP) activity was detec- ted，and cell growth and adhesion were observed by scanning electron microscopy ( SEM) ．In the atrophic nonun- ion model of SD rats，the stent + BMSCs + rhBMP-2 or stent + BMSCs + Ad-BMP-2 complex was implanted into the defect area，which was divided into the rhBMP-2 group and the Ad-BMP-2 group，and the therapeutic effect was e- valuated by X-ray and MicroCT． Results: The surface of the nHA / PA66 stent was smooth and porous，and BMSCs adhered well．Flow cytometry showed high expression of CD29 and CD90 and low expression of CD45 and CD34 in BMSCs．MTT showed that the cells proliferated rapidly after 72 h．Compared with the stent + BMSCs group and the stent + BMSCs + rhBMP-2 group，the ALP activity，the expressions of PDGF，TGF-β , VEGF，FGF，OCN，and ON in the stent + BMSCs + Ad-BMP-2 group were significantly up-regulated ( P＜0. 05) ．12 weeks after surgery， the stent complex in the Ad-BMP-2 group of rats was completely wrapped by newly formed cortical bone，and the surface was smooth and intact．X-ray showed that the complex in the Ad-BMP-2 group was completely wrapped by newly formed cortical bone，and the recovery degree was better than that in the rhBMP-2 group．Micro-CT results showed that compared with the rhBMP-2 group，the bone volume fraction，trabecular thickness，trabecular num- ber，bone mineral density，and bone mineral content in the Ad-BMP-2 group all increased 12 weeks after surgery ( P＜0. 05) ，and the trabecular separation level decreased ( P＜0. 05) ． Conclusion Ad-BMP-2-transfected BM- SCs combined with nHA / PA66 stent material can express bioactivity more effectively，provide a continuous and good microenvironment for the proliferation and differentiation of BMSCs，which is beneficial to promoting local os- teogenic activity and bone defect repair．

Objective To explore the effectiveness of an integrated laparoscopic simulation training course (best essential surgical technique training, BEST) in enhancing laparoscopic peritoneal suturing techniques in surgical residents.Methods As an integrated two-stage program, the BEST course applied basic laparoscopic training system with simple molds in phase Ⅰ training, and then adopted advanced laparoscopic training system, 3D Laparoscope and ex-vivo animal models in phase Ⅱ training. The laparoscopic suturing techniques were practiced in phase Ⅱ training. From August 2021 to July 2024, surgical residents in the second year of the national standardized training program were divided into pilot and control groups based on whether they had undergone the BEST course. Two cases of laparoscopic peritoneal suture were performed by the surgical residents under supervision in the department of gastrointestinal surgery. The operative time, quality of suture, and independent completion rate were compared between the two groups.Results A total of 33 surgical residents (19 in pilot group and 14 in control group) were included in this study, and a total of 66 cases of laparoscopic peritoneal suture were performed (38 in pilot group and 28 in control group). The operative time was significantly shorter in pilot group than that in control group (15.7 min vs. 17.5 min, P=0.025). The quality of suture was significantly better in pilot group compared to control group (P=0.023). In pilot group, all peritoneal sutures were performed by residents independently, whereas in control group, 3 cases (10.7%) were assisted by the supervisor, and the independent completion rate was different significantly (P=0.039).Conclusions The BEST course can help improve surgical residents′ laparoscopic peritoneal suturing techniques and could be promoted in the national standardized training program for surgical residents.

Objective:To investigate the difference in intracranial infection rate between long-tunneled external ventricular drainage(LTEVD)and conventional external ventricular drainage(EVD),as well as the risk factors for intracranial infection.Methods:A retro-spective analysis was performed for the clinical data of 45 patients who were admitted to Department of Neurology Center,The Third Affiliated Hospital of Chongqing Medical University,from January 2020 to December 2022 and underwent EVD,among whom 13 patients underwent LTEVD(LTEVD group)and 32 patients underwent conventional EVD(EVD group).Related data were recorded for both groups,including general information,postoperative catheter-related complications,and postoperative management,to investi-gate the effect on reducing the rate of intracranial infection.According to the presence or absence of intracranial infection after surgery,the patients were divided into the infection group with 10 patients and non-infection group with 35 patients,and related clini-cal data were analyzed to investigate the risk factors for intracranial infection.Results:The LTEVD group had a significantly lower secondary infection rate of catheterization days than the EVD group[2.40‰(1/417)vs.27.19‰(9/331),P=0.009].The duration of catheterization was 14-85 days[27.00(22.50,36.50)days]in the LTEVD group and 8-22 days[9.00(8.00,11.50)days]in the EVD group,suggesting that the LTEVD group had a significantly longer duration of catheterization than the EVD group(P=0.000).The multivariate logistic regression analysis showed that the times of cerebrospinal fluid sampling was an independent risk factor for post-operative intracranial infection in patients undergoing EVD,and the use of LTEVD was a protective factor against intracranial infection after EVD.Conclusion:Compared with conventional EVD,LTEVD can safely prolong the duration of catheterization and reduce the rate of postoperative intracranial infection in patients undergoing EVD.The use of LTEVD procedure and the reduction in the times of cerebrospinal fluid sampling can reduce the risk of postoperative in-tracranial infection.

Objective To explore the interaction between long non-coding RNA growth arrest-specific 5(GAS5)and miR-135b-5p/adenomatous polyposis coli(APC)axis,and to elucidate its biological function in the proliferation,metastasis and invasion of glioma.Methods The relationship of GAS5 expression level with survival rate of glioma patients was analyzed based on CGGA database.qRT-PCR was used to detect the expression level of GAS5 in glioma tissues and cell lines.Human glioma T98 and A172 cell lines were subjected for overexpression and knockdown of GAS5,miR-135b-5p and APC by transfection.Western blotting and qRT-PCR were applied to measure the expression of related genes in glioma tissues or cell lines.CCK-8,Transwell and wound healing assays was conducted to determine the effect of GAS5 on the viability and motility of glioma cells.Moreover,dual luciferase reporter analysis were utilized to elucidate the regulatory mechanisms of GAS5 and miR-135b-5p/APC.Results Analysis on CGGA database showed that the survival rate of glioma patients with low GAS5 expression was significantly decreased(P＜0.001).Western blotting and qRT-PCR indicated that GAS5 was down-regulated in the glioma cell lines and tissues than human normal astrocytes and para-cancer tissues(P＜0.01).The results of CCK-8,Transwell and wound healing assays revealed that overexpression of GAS5 significantly inhibited the viability,invasion and migration abilities in T98 cells when compared with the cells of the vector group(P＜0.01).Dual luciferase reporter analysis displayed that there were binding sites between GAS5 and miR-135b-5p,and the expression of the two was negatively correlated(P=0.019).Further studies suggested that the effect of GAS5 on biological function in glioma cells was through targeting miR-135b-5p,and overexpression of APC reversed the promoting effect of miR-135b-5p on glioma cells(P＜0.01).Western blotting displayed that enhancing miR-135b-5p expression inhibited the expression of APC(P＜0.001),and GAS5 upregulated the expression of APC by targeting miR-135b-5p(P＜0.01).Conclusion GAS5 inhibits the progression of glioma via miR-135b-5p/APC axis,which revealing the molecular regulatory mechanism of GAS5/miR-135b-5p/APC.

Objective To assess the efficacy of clear lens extraction combined with extended depth of focus(EDOF)intraocular lens(IOL)implantation in enhancing visual quality and concurrently opening peripheral angle structures in patients diagnosed with primary angle closure suspect(PACS)and presbyopia.Methods A total of 80 patients with PACS,presbyopia,and transparent lenses were enrolled and divided into two groups based on the type of implanted lens:a control group(n=46)and an experimental group(n=34).The control group underwent clear lens extraction followed by monofocal intraocular lens implantation,while the experimental group underwent clear lens extraction followed by extended depth of focus(EDOF)intraocular lens implantation.Preoperative and postoperative evaluations at 3 months included visual acuity,intraocular pressure,anterior segment structure,defocus curve,and Catquest 9SF-CN questionnaire scores.Adverse events were recorded to assess safety.Results Regarding the angular structure,after 3 months of treatment,results indicated significant increases in central ante-rior chamber depth,angle opening distance at 750 μ m,angle recess area at 750 μ m,trabecular-iris space area at 750 μm,and trabecular-iris angle at 750 μm in both groups compared to preoperative values(all P<0.01).However,no significant differences were observed between the two groups(all P>0.05).For the defocusing curve,visual acuity in the experimental group improved from+1.0 D to-4.0 D after 3 months of treatment(all P<0.05),while the control group showed improvements at+0.5 D,-0.5 D,-1.0 D,-2.0 D,-3.0 D,-3.5 D,and-4.0 D(all P<0.05).Postoperatively at 3 months,the experimental group exhibited superior visual acuity to the control group at-1.0 D to-4.0 D(all P<0.05).According to the Catquest 9SF-CN scale,scores in both groups significantly im-proved after 3 months of treatment(P<0.01),with the experimental group scoring higher than the control group(P<0.01).During the study,transient intraocular pressure elevation occurred in 7 patients(3 in the control group and 4 in the experimental group),but no serious adverse reactions were reported in either group.Conclusions In patients with pseudoexfoliation glaucoma combined with presbyopia,significant improvements in angle structures were observed following clear lens extraction.The implantation of an EDOF IOL notably enhanced postoperative visual quality compared to monofocal IOLs.

Objective:To evaluate the safety and efficacy of digital technology-assisted debridement and bone and soft tissue reconstruction in the treatment of chronic osteomyelitis of the tibia.Methods:This retrospective study analyzed clinical data from 38 patients (26 males, 12 females; mean age 45.61±18.36 years, range 16-83 years) with chronic post-traumatic osteomyelitis complicated by soft tissue defects in the tibia, treated at the Department of Orthopaedics, Fourth Medical Center of PLA General Hospital between June 2021 and June 2023. There were 18 cases of traffic accidents, 6 cases of high-altitude falls, 6 cases of heavy objects and 6 cases of low-energy falls. Lesion sites: 12 cases in the upper segment of the tibia, 12 cases in the middle segment, and 14 cases in the lower segment. According to the Cierny-Mader classification, there were 24 cases of type III and 14 cases of type IV. Before the operation, the "3D point cloud technology" was used to plan the debridement range of bone and soft tissue. During the operation, the optical navigation system was used to monitor the debridement range in real time. The flap was designed by combining "Reading Tablet Treasure" with CT angiography, and the amount of bone graft was predicted by AI algorithm. The surgical method adopted is the Masquelet technique, namely thorough debridement, bone cement occupation and soft tissue repair in the first stage, and bone reconstruction in the second stage. Comparing the calculated bone defect amount and soft tissue defect area before the operation with the actual measured values after debridement. The cure rate of infection was evaluated by using the McKee bone infection treatment criteria after the operation. The visual analogue scale (VAS) for pain, lower extremity functional scale (LEFS), and self-rating anxiety scale (SAS) were used to evaluate the improvement of the quality of life of postoperative patients.Results:38 patients were followed up with a mean follow-up of 13.53±2.37 months. 37 patients' infections were effectively controlled, and 1 patient had a recurrence of infection, with an effectiveness rate of 97% for the treatment of McKee's infections. The preoperative calculated bone defect amount and soft tissue defect area were 51.05±26.31 cm 3 and 68.42±43.45 cm 2 respectively, and the actual measured values after debridement during the operation were 51.66±26.35 cm 3 and 68.82±43.76 cm 2 respectively. There was no statistically significant difference before and after the operation ( P>0.05). The interval between the first and second stage surgeries was 10.36±1.61 weeks, and all flaps survived after the first stage surgery. Two months after the operation, one case had recurrent osteomyelitis. After palliative treatment, sinus tracts were formed at the infection site. At the 12-month regular dressing change follow-up, there were still purulent secretions in the sinus tracts. There was no recurrence of infection after primary debridement in 37 cases, and the bone grafts healed. The bone healing time was 3.58±0.97 months. The postoperative VAS, LEFS, and SAS scores were 1.00±0.91, 66.68±7.91, and 34.30±4.29, respectively, which were significantly improved compared with the preoperative scores of 7.54±1.52, 21.22±4.29, and 52.70±6.74, respectively, and the difference was statistically significant ( P<0.05). Conclusions:The application of digital technology to precisely design the debridement range of bone and soft tissue, and the real-time holographic visualization monitoring of the debridement range during the operation can achieve precise debridement of bone and soft tissue and personalized and precise repair of soft tissue defects. It is a safe and effective technique for the treatment of chronic osteomyelitis of the tibia.
