BACKGROUND:Impaired hamstring muscle strength,anterior patellar pain,high incidence of osteoarthritis,and loss of proprioception after anterior cruciate ligament reconstruction lead to poor functional recovery due to a higher incidence of osteoarthritis and loss of proprioception.Arthroscopic repair of the anterior cruciate ligament combined with dynamic or static internal brace repair preserves the original ligament structure and results in favorable short-term outcomes. OBJECTIVE:To prospectively observe the efficacy and imaging findings of modified double-bundle arthroscopic repair of the anterior cruciate ligament after Sherman type Ⅰ injury METHODS:From January 2020 to September 2022,a total of 60 patients with anterior cruciate ligament injury admitted at the Department of Sports Medicine,Foshan Hospital of Traditional Chinese Medicine were included and divided into two groups(n=30 per group)according to the treatment protocols.The functional repair group was treated with double bundle repair combined with internal brace fixation,and the reconstruction group was treated with single bundle anatomical reconstruction of autologous hamstring muscle.All cases were followed up for 12 months after surgery,and International Knee Documentation Committee score,Lysholm score and KT-1000 difference between the affected and healthy sides of the two groups were evaluated at 3,6 and 12 months after surgery. RESULTS AND CONCLUSION:Three months after surgery,International Knee Documentation Committee scores,Lysholm scores and KT-1000 difference between the affected and healthy sides were significantly different between the two groups(P＜0.05),and the functional repair group was better than the reconstruction group.At 6 and 12 months after surgery,there was no significant difference in International Knee Documentation Committee score,Lysholm score and KT-1000 difference between the two groups(P＞0.05).To conclude,anterior cruciate ligament repair preserves the original ligament structure,avoids drilling larger marrow tracts and removing autologous tendons for reconstruction,reduces the damage to the original normal structure,and has fewer complications.Early postoperative efficacy is better than that of anterior cruciate ligament reconstruction with stumps,but there is no significant difference in the efficacy of the two groups 6 months after surgery.

ObjectiveTo explore the mechanism of Huanglian Wendantang on damp-heat type diabetes enteropathy rats based on the G protein coupled bile acid receptor 5/glucagon like peptide-1 （TGR5/GLP-1） signaling pathway and intestinal flora. MethodsA total of 72 male Sprague Dawley （SD） rats were adaptively fed for one week. Twelve SD rats were randomly selected as a blank group and fed with an ordinary diet. The rest of the SD rats were fasted for 12 hours without water. A rat model with damp-heat type diabetes enteropathy was made by left intraperitoneal injection of streptozotocin （55 mg·kg^-1） and high sugar and high fat diet （20% sucrose solution + high fat diet） in a humid and hot environment （artificial climate box： temperature 30-34 ℃， relative humidity： 85%-95%）. After successful modeling， the rats were randomly divided into a model group， a metformin group （200 mg·kg^-1）， low-dose， medium-dose， and high-dose Huanglian Wendantang groups （7.10， 14.20， 28.39 g·kg^-1）， with 12 rats in each group. The normal group and the model group were orally administered with physiological saline once a day for 6 consecutive weeks. During the observation period， the weight and blood glucose levels of rats were measured and recorded weekly. After the administration， fresh feces were collected from rats， and 16S rRNA sequencing technology was used to study the differences and changes in intestinal flora among different groups. The levels of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） in the serum of rats were detected by enzyme-linked immunosorbent assay （ELISA）， and the pathological morphological changes of colon tissue were examined. The expression of TGR5 and GLP-1 in colon tissue was detected by immunohistochemistry， and the expression of TGR5 and GLP-1 proteins in colon tissue was measured by Western blot. ResultsCompared with the blank group， the model group showed a decrease in body weight， an increase in blood glucose， and significant damp-heat symptoms. The levels of IL-6 and TNF-α in serum were significantly increased （P<0.01）. The expression of TGR5 and GLP-1 was decreased （P<0.01）， and the pathogenic bacteria were increased. Compared with the model group， the treatment groups exhibited improvements in body weight， blood glucose levels， and damp-heat syndrome in rats. Among them， the high-dose group of Huanglian Wendantang displayed the most significant improvement effect， with significantly reduced inflammation levels （P<0.01） and elevated expression of TGR5 and GLP-1 （P<0.01）. Colonic pathological sections showed that Huanglian Wendantang could effectively ameliorate colonic pathological changes. The 16S rRNA sequencing result indicated a significant increase in beneficial bacteria in the treatment groups. ConclusionHuanglian Wendantang can effectively ameliorate the damp-heat symptoms and blood glucose levels in rats with damp-heat type diabetes enteropathy， and it may exert an effect by regulating the TGR5/GLP-1 signaling pathway and intestinal flora disorder.

Objective:To analyze the application value of ultrasound Thyroid Imaging Reporting and Data System (TI-RADS) classification in the differential diagnosis of thyroid nodules and its correlation with patients' midkine, thymidine kinase 1, and thyroid function indicators.Methods:This study was a prospective study. A total of 108 patients with thyroid nodules (120 nodules) who visited Jinan 2 nd People's Hospital from December 2022 to February 2024 were included. Ultrasound examinations were conducted to complete the TI-RADS classification, and serum levels of midkine (MK) and thymidine kinase 1 (TK1), as well as thyroid function indicators, were measured. Based on the patients' pathological results, the consistency between the TI-RADS diagnostic results and the pathological findings was analyzed. The diagnostic efficacy of TI-RADS classification was calculated. The incidence of malignant nodules across various TI-RADS categories was assessed, and the differences in serum levels of MK, TK1, and thyroid function indicators between patients with benign and malignant nodules were compared. Additionally, a correlation analysis was performed to analyze the correlation between the TI-RADS classification of thyroid nodules and the serum levels of MK, TK1, and thyroid function indicators. Results:Pathological examination results revealed 38 malignant nodules and 82 benign nodules. The consistency between ultrasound TI-RADS classification diagnoses and pathological results was good ( Kappa = 0.90, P < 0.001), with diagnostic sensitivity, specificity, and accuracy of 86.84% (33/38), 97.56% (80/82), and 94.17% (113/120), respectively. Among the ultrasound TI-RADS classifications, the malignant rates for category Ⅳb and category Ⅴ thyroid nodules were the highest, at 92.00% (23/25) and 100.00% (10/10), respectively. Serum levels of MK, TK1, and thyroid-stimulating hormone (TSH) were significantly higher in patients with malignant thyroid nodules than in those with benign thyroid nodules (all P < 0.05). Correlation analysis indicated that TI-RADS classification was positively correlated with serum levels of MK, TK1, and TSH ( r = 0.56, 0.60, 0.52, all P < 0.05). Conclusions:Ultrasound TI-RADS classification can be used to differentiate the nature of thyroid nodules, demonstrating high accuracy with low risks of missed or misdiagnoses. It is also closely related to indicators such as MK, TK1, and TSH, providing a basis for the detection of thyroid cancer.

Objectives:To systematically evaluate the incidence and risk factors of titanium mesh subsidence following anterior cervical corpectomy and fusion(ACCF),and to explore the clinical impact of titanium mesh subsidence.Methods:Databases including CNKI,WangFang,VIP,China Biology Medicine disc(CBM),PubMed,Embase,Cochrane Library,and Web of Science were searched for case-control and cohort studies published from the inception of each database to June 2024 about the risk factors of titanium mesh subsi-dence following ACCF.The Newcastle-Ottawa scale(NOS)was used to assess the quality of the included studies.Basic information(first author,publication year,study type,definition of subsidence,assessment time,sample size,number of subsidence cases,and subsidence incidence),reported risk factors(age,sex,BMI,sur gical segment,number of surgical segments,smoking,hypertension,diabetes,fusion segment height,C2-7 Cobb angle,segment angle,vertebral body quality,titanium mesh tilt angle,titanium plate type,screw-plate angle,and titanium mesh placement),cervical JOA score,JOA score improvement rate,and fusion rate were extracted and analyzed using Stata 18.0 software for meta-analysis.Results:A total of 16 studies were in-cluded,and all were case-control studies with NOS scores ≥7.A total of 1562 patients were included,with 555 cases of titanium mesh subsidence.The meta-analysis showed that the incidence of titanium mesh subsi-dence after ACCF was 37％.Risk factors for titanium mesh subsidence included older age[MD=2.680,95％CI(1.228,4.132),P=0.000],female[OR=0.71,95％CI(0.56,0.90),P=0.004],smoking[OR=1.924,95％CI(1.108,3.342),P=0.020],osteoporosis[MD=-62.997,95％CI(-86.670,-39.323),P=0.000],a big number of surgical seg-ments[OR=0.096,95％CI(0.054,0.172),P=0.000],posterior placement of titanium mesh[MD=0.743,95％CI(0.605,0.968),P=0.026],excessive intervertebral distraction[MD=1.317,95％CI(0.752,1.881),P=0.000],seg-ment angle(titanium mesh expansion angle)[MD=0.887,95％CI(0.117,1.657),P=0.024],and a big titanium mesh tilt angle[MD=4.475,95％CI(1.725,7.225),P=0.001].Titanium mesh subsidence was associated with a decrease in cervical JOA score[MD=-0.542,95％CI(-0.947,-0.137),P=0.009],JOA score improvement rate[MD=-11.003,95％CI(-15.315,-6.691),P=0.000],and cervical fusion rate[OR=3.003,95％CI(1.019,8.854),P=0.046].Conclusions:The current evidence indicates that older age,female,smoking,osteoporosis,a big number of surgical segments,posterior placement of titanium mesh,excessive intervertebral distraction,and big titanium mesh expansion angle(segment angle)and titanium mesh tilt angle are the risk factors for titanium mesh subsidence after ACCF.Cage subsidence after ACCF can impair intervertebral fusion and reduce the overall effectiveness of the surgery,and therefore warrants careful clinical attention.

Pulmonary hypertension (PH) is a group of progressive diseases characterized by pulmonary vascular remodeling,and some patients already have right heart insufficiency at the time of diagnosis. Therefore,early diagnosis of PH is essential to improve patients' quality of life and prolong survival. Biomarkers are an important indicator for early diagnosis of the disease,and there are many traditional biomarkers for PH diagnosis,but the sensitivity and specificity are low. With the progress of research,some new biomarkers have been shown to predict disease progression in early PH and play an important role in the early diagnosis of PH. This study reviews the research progress of biomarkers of PH from the aspects of right heart insufficiency,endothelial dysfunction,pulmonary artery smooth muscle dysfunction,inflammation,and in situ thrombosis to provide exploration direction and reference value for early diagnosis of PH.
