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 evaluate the efficacy and safety of plasma-derived human coagulation factor Ⅷ (FⅧ) in the treatment of patients with hemophilia A. 【Methods】 A multi-center and open, SAT(single-arm trials) clinical study was conducted. A total of 54 subjects with hemophilia A were enrolled in 5 research centers. FⅧ was injected according to the subjects' weight, severity of disease and other factors, and the transfusion efficiency of FⅧ activity at 10 min after the first infusion of the first bleeding event was taken as the main efficacy indexes. The improvement scores of bleeding symptoms and signs within 24 h after the first infusion of the first bleeding event were the secondary efficacy indexes. The pathogenic microbial indexes and FⅧ inhibitors were detected on 90(th) and 180(th) day after treatment. 【Results】 The transfusion efficiency of FⅧ activity of 54 subjects at 10 min after the first infusion was 171.9% on average, with median of 169.5%, both higher than the target value of 100%. Within 24 h after the first infusion, the improvement of bleeding symptoms and signs of the subjects were scored, among which 19 cases (35.2%) were "obvious", 35 cases (64.8%) were "good", and the total clinical effective rate reached 100%. Five subjects (9.3%) had six drug-related adverse events. On 90(th) and 180(th) day after treatment, hepatitis B surface antigen, hepatitis C antibody, HIV antibody, treponema pallidum antibody and FⅧ inhibitors were detected, and no negative to positive cases were found. 【Conclusion】 After infusion, the FⅧ preparation can significantly improve the FⅧ activity level in hemophilia A patients in a short period of time, which has high infusion efficiency and can achieve better treatment efficacy, and can also effectively control and relieve bleeding symptoms and signs, with good overall safety.

【Objective】 To explore the recruitment and retention strategy of blood donors by investigating the age composition of blood donors in some areas of China, so as to promote blood donation and enhance clinical blood supply. 【Methods】 Through the working platform of Practice Comparison Working Group of China’s Mainland Blood Collection and Supply Institutions, the average age and age composition of blood donors from 22 blood centers were collected, and statistical analysis was conducted after eliminating invalid data. 【Results】 The median average age of blood donors during the survey year was 30.02.The median age in 2.89% of the blood centers was lower than 25. The average age of different genders was statistically significant only in 2018(P<0.05). Fot first-time blood donors, the median constituent ratio of donors <25 and ≥25 years old was 54.53% and 44.28%, with median retention rate at 10.30% and 9.61%, respectively. The median overall participation rate of blood donors was 2.7%, with median participation rate of blood donors <25 years old at 5.1%. 【Conclusion】 The recruitment and retention of blood donor is crucial to enhance clinical blood supply. Blood donors <25 years old, with a longer period for future donation, should be the main target of blood donation recruitment. Meanwhile, the revision of upper age limit for blood donation is another important initiative to grow the blood donor pool.

【Objective】 To provide reference for fine management of blood donors by classifying and analyzing different types of blood donors from domestic blood stations. 【Methods】 The resident population of 15 regions in China from 2016 to 2019 were taken as the research object, among which the blood donors were divided into three categories: age-eligible citizens, registered donors and donated donors. The average value and proportion of the three categories were calculated and statistically analyzed. 【Results】 The resident population of the 15 regions varied greatly. The mean 95% CI of the proportion of age-eligible citizens to resident population from 2016 to 2019 was (60.16%, 67.84%); registered donors to age-eligible citizens and resident population was (2.21%, 2.86%) and (1.41%, 1.79%), respectively; donated donors to registered donors, age-eligible citizens and resident population was (84.63%, 91.68%), (1.93%, 2.55%) and(1.23%, 1.59%), respectively. 【Conclusion】 There were differences in the number and proportion of different types of blood donors in different regions. The fine management of blood donors can help blood stations carry out more effective recruitment and retention strategies.

Objective:To investigate the value of machine learning-based computed tomography (CT) images radiomics analysis in preoperative evaluation of surgical portal vein-superior mesenteric vein (PV-SMV) invasion in patients with pancreatic ductal adenocarcinoma (PDAC).Methods:The retrospective study was conducted with 156 consecutive PDAC patients who were underwent surgery at the Affiliated Wuxi No.2 People's Hospital of Nanjing Medical University between January 2010 and July 2021. There were 95 males and 61 females, with the age of (65.7±8.2) years. Patients were randomly split into training set and validation set by a ratio of 3∶2. Minimum redundancy maximum relevance was used to select radiomic features, which were extracted from contrast-enhanced CT images. Five machine learning classifiers were developed, and those models' area under the curve (AUC) values were compared with the conventional radiologic-feature-based evaluation.Results:Ninety-four and 52 patients were included into the training set and validation set, respectively. Their PV-SMV invasion rates were confirmed by intraoperative exploration with 31.9%(30/94) and 40.3%(25/61), respectively. Five models: LASSO regression, random forest, support vector machine, k-nearest neighbor and Naive Bayesian, were established based on ten features from CT images radiomics, and LASSO regression model achieved the highest AUC value compared with the other four models (all P<0.05). Compared with the conventional radiologic evaluation, the LASSO regression model had higher AUC (0.920 vs. 0.752) and sensitivity (92.0% vs. 86.5%)(both P<0.05). Conclusion:Machine learning-based CT images radiomics analysis can be used to evaluate PV-SMV invasion status preoperatively in PDAC. The LASSO regression model showed better performance than the conventional radiologic evaluation.

Over recent decades, many studies have reported that hypocrellin A (HA) can eliminate cancer cells with proper irradiation in several cancer cell lines. However, the precise molecular mechanism underlying its anticancer effect has not been fully defined. HA-mediated cytotoxicity and apoptosis in human lung adenocarcinoma A549 cells were evaluated after photodynamic therapy (PDT). A temporal quantitative proteomics approach by isobaric tag for relative and absolute quantitation (iTRAQ) 2D liquid chromatography with tandem mass spectrometric (LC-MS/MS) was introduced to help clarify molecular cytotoxic mechanisms and identify candidate targets of HA-induced apoptotic cell death. Specific caspase inhibitors were used to further elucidate the molecular pathway underlying apoptosis in PDT-treated A549 cells. Finally, down-stream apoptosis-related protein was evaluated. Apoptosis induced by HA was associated with cell shrinkage, externalization of cell membrane phosphatidylserine, DNA fragmentation, and mitochondrial disruption, which were preceded by increased intracellular reactive oxygen species (ROS) generations. Further studies showed that PDT treatment with 0.08 µmol/L HA resulted in mitochondrial disruption, pronounced release of cytochrome , and activation of caspase-3, -9, and -7. Together, HA may be a possible therapeutic agent directed toward mitochondria and a promising photodynamic anticancer candidate for further evaluation.

Objective To analyze clinicopathologic features of sebaceoma. Methods Clinical, pathologic and immunohistochemical findings from 31 cases of sebaceoma were retrospectively analyzed. The clinicopathologic features of sebaceoma were investigated. Results There were 9 males and 22 females. The patients′ age was 53.90 ± 15.40 years, and the clinical course was 9.41 ± 13.75 years. Sebaceoma predominantly affected the face. The common lesion of sebaceoma was red, yellowish?red, skin?colored or slight brown papules, with no subjective symptoms in most cases. Histopathologically, neoplasms had symmetric structures, and were located in the dermis. Epidermal involvements were found in 9 cases. The neoplasm cells were mainly composed of basaloid cells, a few mature sebocytes and some transition cells. The proportion of mature sebocyts was less than 1%in 26 cases, less than 20%in 2 cases, and 20%-40%in 3 cases. Mitoses were occasionally found in 5 cases. One patient was complicated by eccrine poroma. Varying amounts of ducts were found in all the patients. Immunohistochemical staining showed that epithelial membrane antigen was expressed on ducts and mature sebocytes in all the patients, while epithelial antigen was undetected in any of the patients. Carcinoembryonic antigen, androgen receptor and D2?40 were found in 20, 24 and 28 patients with sebaceoma, respectively. Conclusions The diagnosis of sebaceoma mainly depends on histopathological examination. Combined immunohistochemical detection of epithelial membrane antigen, androgen receptor and D2?40 is beneficial to its differential diagnosis.

Gliomas are extremely aggressive brain tumors with a very poor prognosis. One of the more promising strategies for the treatment of human gliomas is targeted immunotherapy where antigens that are unique to the tumors are exploited to generate vaccines. The approach, however, is complicated by the fact that human gliomas escape immune surveillance by creating an immune suppressed microenvironment. In order to oppose the glioma imposed immune suppression, molecules and pathways involved in immune cell maturation, expansion, and migration are under intensive clinical investigation as adjuvant therapy. Toll-like receptors (TLRs) mediate many of these functions in immune cell types, and TLR agonists, thus, are currently primary candidate molecules to be used as important adjuvants in a variety of cancers. In animal models for glioma, TLR agonists have exhibited antitumor properties by facilitating antigen presentation and stimulating innate and adaptive immunity. In clinical trials, several TLR agonists have achieved survival benefit, and many more trials are recruiting or ongoing. However, a second complicating factor is that TLRs are also expressed on cancer cells where they can participate instead in a variety of tumor promoting activities including cell growth, proliferation, invasion, migration, and even stem cell maintenance. TLR agonists can, therefore, possibly play dual roles in tumor biology. Here, how TLRs and TLR agonists function in glioma biology and in anti-glioma therapies is summarized in an effort to provide a current picture of the sophisticated relationship of glioma with the immune system and the implications for immunotherapy.
