Objective:To discuss the clinical curative effect of the treatment of bundling bone fragment with figure-of-eight suture through double bone tunnels in the chronic bong mallet finger.Methods:A retrospective analysis was performed on patients with chronic bong mallet fingers who underwent surgery in the Department of Hand and Foot Microsurgery of Nanjing Jiangbei Hospital from May 2021 to February 2023. During the procedure, made into transverse double bone tunnels on the base of the distal phalanx with 0. 8 mm Kirschner wire, bundling bone fragment with figure-of-eight suture through double bone tunnels, then fixed with Kirschner wire elastic compression. Removal of the Kirschner wire 3 weeks after the procedure, the active flexion and extension range of the joints of the affected finger and the corresponding finger were measured at the last follow-up, then the range of motion (ROM) of the distal interphalangeal joint (DIPJ) and total action movement (TAM) of the fingers (affected and healthy finger) were recorded. The curative effects were evaluated according to the TAM system of the American Association of Hand Surgeons, including 4 grades: excellent, good, fair, and poor. SPSS 13. 0 software was used for statistical analysis of the data, and the measurement data conforming to normal distribution were expressed as Mean ± SD. The ROM of DIPJ and TAM of the affected finger were compared with the corresponding healthy finger 6 months after surgery by a paired sample t test. P<0. 05 indicates that the difference is statistically significant. Results:A total of 30 patients (30 digits) were enrolled, including 19 males and 11 females, and the age ranged from 18 to 62 years old, with an average age of 31 years old. The time from injury to operation was 24 to 65 days (mean of 35 days) . According to Wehbe and Schneider classification, there were 8 cases of type Ⅰa, 6 cases of type Ⅰb, 7 cases of type Ⅱa, 5 cases of type Ⅱb, 2 cases of type Ⅲa and 2 cases of type Ⅲb. All incisions healed well, the intraoperative blood loss was minimal, with no infection. All 30 cases were followed up for 6 to 7 months. All fractures were well aligned and healed, malformed fingers were completely corrected, and no needle tunnel infection or needle breakage were observed. At the last follow-up, the differences of the ROM of the DIPJ [ (30. 2±3. 5) °vs. (30. 4±3. 3) °, t=2. 57, P=0. 463] and the TAM [ (235. 3± 3. 6) ° vs. (237. 7± 4. 2) °, t=1. 78, P= 0. 247 ] between the affected and healthy fingers were not statistically significant. Finger function assessment: 27 cases were excellent, and 3 cases were good, and the excellent and good rate was 100%. Conclusion:Satisfactory therapeutic outcome for the treatment of chronic bong mallet finger deformity can be achieved by bundling bone fragment with figure-of-eight suture through double bone tunnels. It is an effective and practical method.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Objective To explore the predictive factors of axillary lymph node metastasis in breast cancer,and to provide a basis for clinical decision-making under the DIP payment mode of medical insurance.Methods A total of 715 patients with breast cancer were divided into the metastasis group(n=309)and the non-metastasis group(n=406)according to the postoperative paraffin pathological results.Data of age＞60 years old,menopausal status,body mass index(BMI)＞24 kg/m2,hyperglycemia(GLU＞6.1 mmol/L),high triglycerides(TG＞1.7 mmol/L),maximum diameter of the tumor,the distance between the tumor and nipple and the quadrant where the tumor located were compared between the two groups.The expression levels of estrogen receptor(ER),progesterone receptor(PR),nuclear proliferation antigen(Ki-67)and human epidermal growth factor receptor-2(Her-2)in breast cancer tissue samples were detected by histological grading and immunohistochemistry.The consistency,sensitivity and specificity of chest CT and breast ultrasound were examined,taken the pathological diagnosis as the gold standard.Results Compared with the non-metastatic group,the proportion of maximum diameter of tumor＞2 cm,histological grade Ⅲ,high Ki-67 and high ER expression,tumor located in the outer upper quadrant,the distance＞3 cm between tumor and nipple were increased in the metastatic group,and the proportion of high level of TG was decreased in the metastatic group(P＜0.05).The consistency between chest CT and pathological diagnosis was better than that of breast ultrasound(Kappa was 0.493 and 0.353 respectively,P＜0.05).Logistic regression analysis showed that histological grade Ⅲ,high expression of ER,maximum diameter of tumor＞2 cm,and chest CT diagnosis were risk factors for axillary lymph node metastasis(P＜0.05).Conclusion The combined application of the predictive factors of axillary lymph node metastasis of breast cancer could provide certain reference for clinical decision-making under the background of DIP payment mode of medical insurance.

Objective To evaluate the role of preoperative serological indexes in predicting long-term survival and tumor recurrence of hepatocellular carcinoma (HCC) patients after liver transplantation, aiming to explore its significance in expanding the Milan criteria. Methods Clinical data of 669 recipients undergoing liver transplantation for HCC were retrospectively analyzed. The optimal cut-off value was calculated by the receiver operating characteristic (ROC) curve. The risk factors affecting the overall survival and recurrence-free survival rates of HCC patients after liver transplantation were identified by univariate and multivariate regression analyses. The correlation between preoperative serum liver enzymes and pathological characteristics in HCC patients was analyzed. The predictive values of alpha-fetoprotein (AFP) combined with γ -glutamyl transferase (GGT) and different liver transplant criteria for the survival and recurrence of HCC patients after liver transplantation were compared. Results Exceeded Milan criteria, total tumor diameter (TTD) > 8 cm, AFP > 200 ng/mL and GGT > 84 U/L were the independent risk factors for the overall survival and recurrence-free survival rates of HCC patients after liver transplantation (all P < 0.05). Correlation analysis showed that preoperative serum GGT level was correlated with TTD, number of tumor, venous invasion, microsatellite lesions, capsular invasion, tumor, node, metastasis (TNM) stage, Child-Pugh score and exceeded Milan criteria (all P < 0.05). Milan-AFP-GGT-TTD (M-AGT) criteria were proposed by combining Milan criteria, TTD with serum liver enzyme indexes (AFP and GGT). The 5-year overall survival and recurrence-free survival rates of HCC recipients who met the M-AGT criteria (111 cases of exceeded Milan criteria) were significantly higher than those who met Hangzhou criteria (both P < 0.05), whereas had no significant difference from their counterparts who met the University of California at San Francisco (UCSF) criteria (both P > 0.05). Conclusions Preoperative serological indexes of AFP and GGT could effectively predict the long-term survival and tumor recurrence of HCC patients after liver transplantation. Establishing the M-AGT criteria based on serological indexes contributes to expanding the Milan criteria, which is convenient and feasible.

OBJECTIVE To evaluate the effectiveness， safety， economy， innovation， suitability and accessibility of recombinant Mycobacterium tuberculosis fusion protein （EC）， and to provide evidence for selecting skin detection methods for tuberculosis infection diagnosis and auxiliary diagnosis of tuberculosis. METHODS The effectiveness and safety of EC compared with purified protein derivative of tuberculin （TB-PPD） were analyzed by the method of systematic review. Cost minimization analysis， cost-effectiveness analysis and cost-utility analysis were used to evaluate the short-term economy of EC compared with TB-PPD， and cost-utility analysis was used to evaluate the long-term economy. The evaluation dimensions of innovation， suitability and accessibility were determined by systematic review and improved Delphi expert consultation， and the comprehensive score of EC and TB-PPD in each dimension were calculated by the weight of each indicator. RESULTS The scores of effectiveness， safety， economy， innovation and suitability of EC were all higher than those of TB-PPD. The affordability scores of the two drugs were consistent， while the availability score of EC was lower than those of TB-PPD. After considering dimensions and index weight， the scores of effectiveness， safety， economy， innovation， suitability， accessibility and the comprehensive score of EC were all higher than those of TB-PPD. CONCLUSIONS Compared with TB-PPD， EC performs better in all dimensions of effectiveness， safety， economy， innovation， suitability and accessibility. However， it is worth noting that EC should further improve its availability in the dimension of accessibility.

Objective:To explore the clinical value of adjuvant therapy in patients with T3 gallbladder cancer (GBC) who have undergone R0 resection.Methods:Clinical and pathological data from 415 patients with T3 GBC who underwent surgical treatment in 7 tertiary centers in China from January 2013 to December 2018 were collected,including 251 males and 164 females,aged (61±11)years (range: 26 to 88 years). Depending on whether to receive adjuvant therapy after radical resection,the patients were divided into the radical resection group alone (group A, n=358) and the radical resection combined with the postoperative adjuvant therapy group (group B, n=57). The general data of the two groups were matched 1∶1 by propensity score matching method,and the caliper value was 0.02.Clinicopathological characteristics,overall survival and disease-free survival of the two groups were compared.The Cox regression model was used for multivariate analysis,and patients with at least one or more independent risk factors were classified as high-risk clinicopathological subtypes. Subgroup analysis was performed to assess the clinical value of adjuvant therapy after radical resection in patients with high-risk clinicopathological subtypes. Results:After the matching,there were 42 patients in each of the two groups. The incidence of gallbladder cancer and the number of dissected lymph nodes in group B after cholecystectomy were higher than those in group A ( χ 2=9.224,2.570,both P<0.05). There were no significant differences in overall survival rate and disease-free survival rate between the two groups before and after matching (all P>0.05). The results of the univariate and multivariate analysis showed that CA19-9>39 U/ml,nerve invasion,tumor location (liver side or bilateral),TNM stage ⅢB to ⅣB ,poorly differentiated tumor were independent prognostic factors of overall survival and disease-free survival of patients with T3 stage gallbladder cancer (all P<0.05).Three hundred and twenty-nine patients(79.3%) had high-risk clinicopathological subtypes,and the median survival time after curative resection with and without adjuvant therapy was 17 months and 34 months respectively,and the 3-year and 5-year overall survival rates were respectively 40.0%,21.3% and 46.0%,46.0% ( χ 2=4.042, P=0.044);the median disease-free survival time was 9 months and 13 months,and the 3-year and 5-year disease-free survival rates were 23.4%,13.6% and 30.2%,18.2% ( χ 2=0.992, P=0.319). Conclusions:Postoperative adjuvant therapy following radical surgery did not yield significant improvements in the overall survival and disease-free survival rates of patients diagnosed with T3 gallbladder cancer. However, it demonstrated a significant extension in the overall survival rate for patients presenting high-risk clinicopathological subtypes.
