Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

Objective:To observe the clinical efficacy of a new type of "firebreak" drainage with skin preservation in the treatment of Fournier's gangrene.Methods:This technique is suitable for patients with perianal necrotizing fasciitis who can tolerate surgery without large area of skin blackness and necrosis. Procedure and key points: (1) The dividing line between inflammatory tissue and normal tissue was determined according to imaging examination and intraoperative exploration; (2) The abscess cavity was cut along the most obvious part of the abscess fluctuation, with a long diameter of 3~4 cm and a short diameter of 1~2 cm; (3) Necrotic tissue was discreetly separated and removed from the main incision to the outer edge of the infection. A fusiform incision was made every 3 to 5 cm, with a long diameter of 2 to 3 cm and a short diameter of 1 cm, and discreetly separated until the normal tissue, and a hose was hung between the adjacent incisions for drainage. (4) Each adjacent edge cut between the stealth separation and hanging hose drainage, forming a "firebreak"; (5) Rinse the wound repeatedly; (6) If the infection invades the rectum, colostomy is performed as required. The case data of 11 patients with perianal necrotizing fasciitis admitted to the Second Affiliated Hospital of Nanjing University of Chinese Medicine from July 2019 to February 2023 were retrospectively analyzed. All patients were treated with emergency surgical debridement by "firebreak" drainage with skin preservation.Results:All 11 cases were cured with 100%. One case underwent multiple operations. The hospitalization time was 11-46 days, with an average of 22 days. The wound healing time was 28-75 days, with an average of 43 days. Except for 1 patient with trauma, all the other patients had no significant anal function injury after surgery. All the 11 patients recovered and were discharged from hospital with a median follow-up of 136 (115-413) days.Conclusions:The "firebreak" drainage based on skin preservation has the advantages of less trauma and faster recovery, and do not cause obvious anal function damage.

Objective:To investigate the risk factors of lymph node metastasis in the cervical region VI (central region) in patients with papillary thyroid microcarcinoma (PTMC) of cN0 stage, and then to determine whether to perform prophylactic central lymph node dissection.Methods:The clinical data of 500 patients with PTMC who underwent surgery from Jan. 2013 to Dec. 2015 in Ningbo First Hospital were retrospectively analyzed. Due to the pathological results, all patients were divided into two groups: central lymph node metastasis (CLNM) positive group and CLNM negative group. SPSS18.0 was used for analyzing.Results:Of the 500 cases of PTMC of cN0 stage, 142 cases had lymph node metastasis. Gender, the maximum tumor diameter, tumor invasion outside the gland, boundary, calcification in tumor, single or multiple lesions, aspect ratio and blood flow were risk factors for CLNM in patients with PTMC of cN0 stage. Multivariate analysis identified that male ( P=0.014) , tumor size ≥0.5 cm ( P=0.03) , tumor invasion outside the gland ( P=0.003) , unclear boundary ( P=0.032) , calcification ( P=0.009) , aspect ratio ≥1 ( P=0.001) were independent predictors factors for CLNM of PTMC. Conclusion:Male, unclear boundary, tumor size ≥0.5cm, tumor invasion outside the gland, calcification, aspect ratio ≥1 are the risk factors of CLNM in patients with cN0 PTMC. Prophylactic central lymph node dissection should be performed for patients without lymph node metastasis but with one risk factor or more.

Objective To investigate the effects of different dosages of bone marrow mesenchymal stromal cells (BMSC) on lung fibrosis. Methods BMSCs with red fluorescence protein (RFP) from male FVB mice were cultured in vitro. Twenty-four female wild type FVB mice were randomly divided into four groups: normal group, model group, BMSC 1 group and BMSC 2 group (n = 6). Mouse pulmonary fibrosis models were induced by bleomycin via single intratracheal perfusion. Twenty-four h after model establishment, mice in BMSC 1 group and BMSC 2 group were injected with 1 × 10~6 BMSCs and 2 × 10~6 BMSCs, respectively through vena caudalis for each mouse. All the animals were sacrificed 21 d after model estalishment, and mouse lung tissue samples were obtained. The pathological changes were observed by light microscopy, the hydroxyproline ( Hyp) contents were measured by alkaline hydrolysis assay, the distribution of RFP( + ) BMSCs and quantitation of RFP were analysed by laser scanning confocal microscopy and immunohistochemistry, the expression of surfactant protein A (SP-A) was detected by immunohistochemistry, and the expression of transforming growth factor-β (TGF-β) and platelet-derived growth factor (PDGF) mRNA was detected by Real-time PCR. Results Compared with model group, the pulmonary fibrosis in BMSC 1 group was significantly alleviated, and that of BMSC 2 group became much more severe.A large number of RFP( +) BMSCs were found in fibrosis area of BMSC 2 group,which exhibited morphology similar to fibroblasts. As far as the expression of SP-A was concerned, normal group was higher than BMSC 1 group, BMSC 1 group was higher than BMSC 2 group and model group (P < 0. 05), while there was no significant difference between BMSC 2 group and model group (P >0. 05). Normal group, BMSC I group, model group and BMSC 2 group fell in the increase order by Hyp contents (P <0.01, P <0.05), and BMSC 2 group, BMSC 1 group, model group and normal group fell in the decrease order by expression of TCF-|$ and PDGF mRNA (P < 0.05). Conclusion Proper dose of BMSC has a favourable effect on bleomycin-induced lung fibrosis, while excessive dose of BMSC can aggravate the fibrosis.

GST/MCP-1 fusion protein was overexpressed in Escherichia coli as inculstion bodies. After isolation of the inclusion bodies, the optimum conditions of denaturation and renaturation were studied. The renatured produts were purified to be electroporetically pure by affinity chromatography on immobilised glutathione. The purified product remains biological activities and can react specifically with MCP-1 antibodies by western blot analysis. The in vitro antitumor effect showed that GST/MCP-1 could activate monocytes and lymphocytes to inhibit the growth of a lung adenocarcinoma cell line A549. In vivo, GST/MCP-1 could inhibit the tumor growth in nude mice. These results suggested that MCP-1 had antitumor effect.
