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.

Innovative drugs are defined as new chemical entities that play a vital role in the treatment and maintenance of human health. While single-target innovative drugs have achieved notable success, they face limitations in addressing the increasingly complex and precise spectra of diseases. The advent of multi-target innovative drugs offers new opportunities, supported by a growing body of pharmacological evidence. Herbal medicines are recognized as valuable sources of multi-target therapeutics due to their proven efficacy in treating complex diseases. However, the identification and validation of such drugs from herbal sources continue to pose significant challenges. This paper presents a comprehensive review of the literature on traditional Chinese medicine, integrated medicine, chemistry, and biology from 2015 to 2025. It summarizes the strategies employed in integrating traditional Chinese and Western medicine for innovative drug development, along with successful application cases. We believe these efforts will deepen understanding of the current landscape, accelerate the discovery of multi-target innovative drugs from herbal medicine, and contribute to addressing major human health challenges.

Objective:Investigation of the relationship between variant angina pectoris syncope and coronary artery spastic targeted location, arrhythmias, and coronary artery stenostic lesion.Methods:This study combined retrospective and prospective registry approaches. Data were sourced from the case database of Henan province "Multicenter Clinical Observation Study of Variant Angina Pectoris". A total of 507 patients with variant angina pectoris who had complete records from June 1980 to December 2022 were consecutively enrolled. Select patients among them who experienced syncope, and analyze the target vessel sites of coronary artery spasm, arrhythmias during variant angina pectoris attacks, and the degree of stenosis in coronary artery lesions.Results:Among 507 variant angina pectoris patients, 88 experienced syncope. Age was (53.9±9.7) years and 66 patients (75.0%) were male. Forty patients (45.5%, 40/88) were aged 50-59 years. The incidence of syncope in variant angina pectoris caused by left anterior descending artery (LAD) spasm, right coronary artery (RCA) spasm, and multivessel coronary artery spasm was 7.4% (15/202), 22.7% (42/185), and 23.6% (25/106), respectively. The latter two were significantly higher than those in the LAD group ( P all<0.05). Among 77 patients with variant angina pectoris syncope, definitive electrocardiogram recordings were available during syncope episodes. All patients exhibited arrhythmias during syncope: 34 cases involved tachyarrhythmias and 43 cases involved bradyarrhythmias. The incidence of rapid arrhythmias in patients with LAD, RCA, and multi-vessel spasm syncope was 72.7% (8/11), 24.3% (9/37), and 54.2% (13/24), respectively, with P<0.05 for the first two. Bradyarrhythmias occurred in 27.3% (3/11) of LAD, 75.7% (28/37) of RCA, and 45.8% (11/24) of multivessel coronary artery spasm syncope cases, with the first two showing P<0.05. Coronary angiography analysis of 56 syncope patients revealed target vessel locations and stenosis severity: 12 patients had LAD lesions and 41 had RCA lesions, stenosis ≥50% occurred in 66.7% (8/12) and 43.9% (18/41) of these lesions, respectively ( P>0.05). Conclusions:Variant angina pectoris syncope predominantly affects middle-aged males. Bradyarrhythmias triggered by RCA spasm are a common cause, while the incidence of syncope shows no significant correlation with the degree of coronary artery stenostic lesion, whether in the LAD or the RCA.

Objective:To study the clinicopathological features of Sjogren′s syndrome (SS) with liver injury and to improve the understanding of this disease.Methods:Forty-nine patients with SS complicated with liver injury were collected from Beijing Ditan Hospital, Capital Medical University from October 2008 to January 2022. All patients underwent ultrasound-guided liver biopsy, and all specimens were stained with HE. The histopathologic characteristics were observed and the pathologic indexes were graded. Immunohistochemical stains for CK7, CK19, CD38, MUM1 and CD10 were performed by EnVision method; and special histochemical stains for reticulin, Masson′s trichrome, Rhodanine, Prussian blue, periodic acid Schiff (PAS) and D-PAS stains were conducted .Results:The age of patients ranged from 31 to 66 years, including 3 males and 46 females. SS combined with drug-induced liver injury was the most common (22 cases, 44.9%), followed by autoimmune liver disease (13 cases, 26.5%, including primary biliary cholangitis in eight cases, autoimmune hepatitis in 3 cases, and PBC-AIH overlap syndrome in 2 cases), non-alcoholic fatty liver disease (NAFLD, 9 cases, 18.4%) and other lesions (5 cases, 10.2%; including 3 cases of nonspecific liver inflammation, 1 case of liver amyloidosis, and 1 case of porto-sinusoidal vascular disease). Among them, 28 cases (57.1%) were associated with obvious interlobular bile duct injury, mainly in SS combined with PBC group and drug-induced liver injury group. Twenty-three cases (46.9%) were associated with hepatocyte steatosis of varying degrees. In SS with autoimmune liver disease group, ISHAK score, degree of fibrosis bile duct injury, bile duct remodeling, lymphocyte infiltration of portal area, and plasma cell infiltration, MUM1 and CD38 expression; serum ALP and GGT, IgM; elevated globulin; positive AMA, proportion of AMA-M2 positive and IgM positive were all significantly higher than those in other groups(all P<0.05). Serum ALT, direct bilirubin and SSA positive ratio in SS combined with drug liver group were significantly higher than those in other groups(all P<0.05). The serum total cholesterol level in SS combined with PBC group ( P=0.006) and NALFD group ( P=0.011) were significantly higher than those in other groups ( P<0.05). Conclusions:The pathologic manifestations of SS patients with liver injury are varied. The inflammatory lesions of SS patients with autoimmune liver disease are the most serious, and the inflammatory lesions of SS patients with non-alcoholic fatty liver disease and non-specific inflammation are mild. Comprehensive analysis of liver histopathologic changes and laboratory findings is helpful for the diagnosis of SS complicated with different types of liver injury.

Objective:To investigate the clinicopathological characteristics of rashes in monkeypox patients through a series of skin biopsies, and examine their pathological features and the most effective tests.Methods:Patients with monkeypox virus infection admitted to Beijing Ditan Hospital from June to August 2023 were identified. Among them, 24 patients underwent skin biopsies for clinical pathological study that were included in this study. Clinical information, rash pictures, and nucleic acid test results were analyzed using histopathology, immunohistochemistry, RNAscope ? hybridization and electron microscopy. Results:All 24 patients were male, including 14 patients with concurrent human immunodeficiency virus infection. Their average age was (32.3±5.4) years. The nucleic acid test confirmed monkeypox virus infection. The clinical feature of monkeypox rashes was solitary rather than clustered distribution, with rashes occurring in similar phase, distinguishing it from herpesvirus. The rashes in these patients were mostly scattered, with an average of (13.0±11.8) rashes, and most commonly present in the perineum, face, limbs, and trunk. The three main pathological features of these rashes were ballooning degeneration of the epidermal spinous cell layer, the characteristic intra-cytoplasmic Guarnieri′s bodies and significant infiltration of inflammatory cells in whole dermal layer. Immunohistochemistry, RNAscope ? hybridization, and electron microscopy can all effectively detect the monkeypox virus. Electron microscopy showed viral replication in various types of skin cells. Conclusions:The study describes the pathological features of monkeypox virus rashes. Pathological examination of skin biopsy samples is helpful to diagnose these rashes. The study suggests that the monkeypox virus has a unique epitheliotropic affinity and can infect various types of cells in the skin.

Objective:To investigate the infection and treatment of helicobacter pylori (HP) in flying personnel, as well as their cognition of HP.Methods:By using cluster sampling method, the flying personnel who recuperated at the Second Sanatorium of Air Force Healthcare Center for Special Services Hangzhou were selected for questionnaire survey. They were divided into positive group and negative group according to whether they were infected with HP. The cognition of HP (such as whether they had known HP, how to detect HP, and the symptoms, infection route, as well as the knowledge on treatment and prevention of HP) were compared between 2 groups. The differences on infection situation at different ages, personal lifestyle, diet and living environment were also compared. The treatment of flying personnel in positive group during their stay in the sanatorium was investigated and analyzed among different age groups.Results:A total of 347 flying personnel were included, with 161 in the positive group and 186 in the negative group. The HP infection rate in the rural population before joining the army was higher than that in the urban population, with a significant difference ( χ2=7.19, P=0.007). But there were no significant differences on whether they had long-term smoking history, preferred strong tea or coffee, spicy and fried food and whether their family members were infected ( χ2=0.05-5.92, all P>0.05). The questionnaire showed that the cognition of the negative group was significantly better than the positive group on whether they understood the infection route, symptoms and preventive measures of HP ( χ2=8.28, 12.00, 48.22, P=0.005, 0.001,<0.001), but there was no difference between 2 groups on whether they had known HP, detection methods and treatment after infection ( P>0.05). The treatment rate in positive group was only 29.19% (47/161), and there was no significant difference in the treatment rate among different age groups ( P>0.05). Conclusions:There is a high HP infection rate in flying personnel on base of the survey. The poor awareness of HP would affect the treatment rate and the basic cognition would be beneficial to active prevention. The survey also shows that the environment factors are seemed more sensitive to HP than dietary habit.
