Objective To explore the influence of blood uric acid (serum uric acid, SUA) and fasting plasma glucose (FPG） on the occurrence of coronary heart disease in patients with type 2 diabetes mellitus (T2DM). Methods T2DM patients admitted to 3201 Hospital from January 2021 to January 2024 were selected and divided into a combined coronary heart disease(CHD) and a simple diabetes mellitus (DM). The clinical data were collected, and the blood SUA and FPG levels were analyzed. The basic characteristics and biochemical indicators of the two groups were analyzed. Risk factors affecting the severity of coronary lesions were identified by multivariate logistic regression analysis. The interaction between SUA and FPG was also evaluated. Results A total of 98 T2DM patients were included in this study, including 53 and 45 patients in the DM and combined CHD groups, respectively. Compared with the DM group, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), triglycerides (TG), SUA and FPG levels were significantly higher in the combined CHD group. The differences were all statistically significant (P<0.05). The multivariate logistic regression model analysis showed that LDL-C (OR=1.490, 95%CI: 1.044-1.824), HDL-C (OR=1.182, 95%CI: 0.846-1.314), TC (OR=1.075, 95%CI: 0.891-1.190), TG (OR=1.695, 95%CI: 1.230-2.164), SUA (OR=1.820, 95%CI: 1.294-2.424) and the FPG level (OR=2.154, 95%CI: 1.532-3.079) could be an independent risk factor for the development of CHD (OR value>1, P<0.05). The results of the interaction analysis showed a positive and additive interaction between SUA and FPG, and the difference was statistically significant (P<0.05). Conclusion Both SUA and FPG levels are independent risk factors for the occurrence of CHD. A positive additive interaction between the two may together contribute to the risk of CHD in T2DM patients.

Objective To investigate the correlation between hyperuricemia and the risk of type 2 diabetes mellitus, and to explore whether hyperuricemia is an independent risk factor of type 2 diabetes mellitus. Methods Using a prospective cohort study design, 300 adult volunteers who underwent physical examinations at the 3201 Hospital were recruited from January to December 2021. They were divided into a high uric acid group and a non-high uric acid group based on their uric acid levels. The incidence of diabetes in people with different uric acid levels was observed within two years through follow-up. SPSS26.0 software was used to statistically analyze the data. Results The data of this study showed that hyperuricemia significantly increased the risk of type 2 diabetes mellitus (P=0.01，OR=3.551). In addition, BMI had a significant impact on the risk of diabetes (P=0.000，OR =0.115), but the impact of age and gender was not statistically significant (both P>0.05). Conclusion Hyperuricemia is positively correlated to the incidence of type 2 diabetes. The higher the uric acid level, the higher the incidence of type 2 diabetes. The uric acid level has a good evaluation value in the incidence of type 2 diabetes mellitus. This finding provides a basis for early intervention of hyperuricemia as a potential risk factor for type 2 diabetes.

Objective This study aims to investigate and analyze the distribution of MN blood type among ethnic minorities in China. Methods Through a systematic retrieval of the 981 literature related to MN blood group distribution, 120 literature, meeting the criteria of this study, with complete data were selected. The literature covers 49 ethnic minorities. SPSS 26 statistical software was used to analyze the data. Results The results showed that among the 49 ethnic minorities in China, the phenotype distribution of MN blood type was MN>MM>NN, with proportions of 42.54%, 41.86%, and 15.06% respectively. The gene frequency for MN blood type exhibited a trend of m>n, with a gene frequency of m being 0.6313 and n being 0.3687. Cluster analysis divided the Chinese ethnic minorities into three groups based on the gene frequency for m, showing the characteristics of Group I>Group II>Group III. Conclusion The MN blood type characteristics in Chinese ethnic minorities show a higher frequency of the M gene compared to the N gene. The frequency of the M gene is higher in southern ethnic minorities than in northern ones. There are significant differences between southwestern ethnic minorities and the Han nationality, but no differences with long-term mixed/settled Han populations.

OBJECTIVE: The investigation of the correlation between ecological factors and the genetic characteristics or metabolites of plants offers valuable insights into the regional causes of genetic and metabolic diversity. Here, Gastrodia elata, a medicinal plant, is employed as a model to explore the environmental factors that influence its genetic characteristics and metabolic accumulations. METHODS: A total of 23 G. elata populations from six cultispecies and 11 cultivated regions were selected based on the predictions of the global geographic information system. The genetic characteristics of these populations were evaluated using highly polymorphic simple sequence repeat markers. Additionally, the metabolic accumulations and antioxidant capacity of mature tubers were measured employing colorimetry and high performance liquid chromatography (HPLC). Ecological data of each region were obtained from the WorldClim-global climate database and harmonized world soil database. To assess the influence of ecological factors on the genetic characteristics and metabolic profiles of G. elata, Pearson's correlation analysis was conducted. RESULTS: Genetic variation among G. elata populations exceeded that within populations. Genetic diverisity, distance and structure manifested regional and species-specific patterns. Metabolic profiling and antioxidant capacity exhibited regional variations. Notably, the Lueyang region demonstrated that a content range of total polysaccharide, total protein, and phenolic glycosides was 9.34%-189.67% higher than the average. Similarly, in the Hubei region, total phenolic content, p-hydroxybenzyl alcohol content, and antioxidant indicators were observed to be higher than the average levels, by 106.57%, 136.47% and 12.50%-91.14%, respectively. Furthermore, ecological factors had a significant comprehensive impact on G. elata genetic characteristics (r > 0.256 and P < 0.05). Multivariate metabolite accumulations in G. elata were influenced by dominant ecological factors. Temperature notably impacted the accumulation of total protein (|r| > 0.528 and P < 0.05). Moisture, encompassing precipitation and soil content, significantly affected the production of phenolic glycosides (|r| > 0.503 and P < 0.05). CONCLUSION The genetic characteristics of G. elata manifested regional and species-specific patterns, with the metabolic accumulations and antioxidant capacity of mature tubers exhibited regional variations. Specifically, multivariate ecological factors comprehensively influenced genetic characteristics. Temperature and moisture played pivotal roles in regulating the accumulations of proteins and phenolic glycosides, respectively. These findings underscore the significant impact of ecological factors on the shaping of G. elata, highlighting their crucial role in enhancing the quality of Chinese medicinal materials.

Objective:To analyze the clinical features of adrenal metastases and summarize the experience of diagnosis and treatment.Methods:The clinicopathological data of 210 patients with adrenal metastases admitted to Peking Union Medical College Hospital from Jan. 1990 to Jun. 2021 were retrospectively analyzed, and the relevant literature was reviewed. The clinical characteristics, primary tumor types, imaging examination methods and diagnosis and treatment methods of adrenal metastases were summarized.Results:Among 210 patients, 153 were males and 57 were females, with an average age of (60±12) years. The average maximum diameter of the tumor was (4.7±2.6) cm, the maximum was 14.5 cm, and the minimum was 0.5 cm. Tumor occurred in 84 cases on the left, 81 cases on the right, and 44 cases bilateral. The primary tumors of 210 patients were 72 cases of lung cancer, 48 cases of renal cancer, 29 cases of hepatobiliary cancer, 18 cases of colorectal cancer, 11 cases of gastric esophageal cancer, 6 cases of pancreatic cancer, 5 cases of breast cancer, 3 cases of melanoma, and 18 cases of other tumors. 108 patients had no obvious clinical symptoms of discomfort, only found in the review of primary tumor or routine physical examination. 102 were primary disease-related symptoms, and 210 patients had no abnormal endocrine signs such as moon face and buffalo back. The median time from diagnosis of primary tumor to adrenal metastasis was 3 months. 95 cases were diagnosed with primary tumor at the same time. The longest time was 228 months. Of the 210 patients, 203 underwent CT, 99 PET-CT, 74 B-ultrasound and 25 MRI. A total of 122 patients were clinically diagnosed as adrenal metastasis by history and imaging examination. One patient was treated with adrenal photon knife, one patient was treated with adrenal artery embolization chemotherapy, and 21 patients were treated with adrenal radiotherapy or CT-guided adrenal radiofrequency ablation. A total of 88 patients were diagnosed as adrenal metastasis by histopathology. Among them, 12 patients were diagnosed by adrenal puncture under CT guidance, 74 patients were diagnosed by adrenal surgery, and 2 patients were further treated with metastatic tumor resection after adrenal metastasis was diagnosed by puncture. Finally, all patients were diagnosed as adrenal metastasis of malignant tumor by pathology, and they continued to be treated with primary tumor.Conclusions:Lung cancer is the most common type of primary adrenal metastases in our hospital. Most of the elderly men have no obvious endocrine-related symptoms and signs. CT is an effective means of examination, supplemented by B ultrasound or MRI diagnostic accuracy will be further improved, but the diagnosis still depends on histopathological examination. For patients with isolated adrenal metastasis, surgical treatment can significantly improve the prognosis. However, comprehensive treatment should be carried out according to the general situation of patients, the type and biological behavior of primary tumors, and the characteristics of metastatic tumors, so as to achieve the best curative effect.

Objective To explore the epidemic characteristics of pyogenic liver abscess (PLA) in the elderly and to screen risk factors affecting prognosis. Methods A total of 406 elderly PLA patients admitted to our hospital from April 2018 to December 2022 were selected to collect their clinical data and Microbiological culture; According to the treatment results, it is divided into improvement (Group A), deterioration or death (Group B), and logistic regression model is used to analyze the prognostic factors. Results Among the 406 patients, there were 274 males and 132 females; The common manifestation was fever in 341 cases (83.99%); The main complications were 158 cases of diabetes (38.92%), followed by 77 cases of biliary diseases (18.97%). Among 243 cases with positive Microbiological culture, 124 cases (51.03%) were Escherichia coli, followed by 46 cases (18.93%) of Pseudomonas aeruginosa. There were 258 cases in group A and 148 cases in group B. There were significant differences between the two groups in age, liver abscess diameter, diabetes, Alkaline phosphatase, lactate deaminase, Prothrombin time, total bilirubin and globulin levels (P<0.05). Age, diameter of liver abscess, Alkaline phosphatase and Prothrombin time were independent risk factors for poor prognosis (P<0.05). Conclusion The main symptoms of elderly PLA patients are fever, diabetes and other diseases. Most of the pathogenic bacteria are Escherichia coli. Age, diameter of liver abscess, Alkaline phosphatase and Prothrombin time are factors affecting the prognosis.

Objective To preliminarily analyze the influencing factors of benign thyroid nodule malignant transformation and provide a basis for early intervention of benign thyroid nodule malignant transformation. Methods Selected 158 patients with benign thyroid nodules who visited our hospital from January 2019 to January 2022 for inclusion in the study, and followed up for 3 year to observe whether the nodules had malignant changes. The age, gender and dietary habits were collected. 3 mL of fasting venous blood of subject were collected , and the level of TT3, TT4, FT3, FT4, TSH, TgAb, CEA, thyroglobulin and calcitonin were collected. Results The results of this study suggest that the plasma levels of serum TgAb, TSH, TT4, TT3, FT3, FT4, CEA, thyroglobulin, and calcitonin of subjects were not statistically significant between sexes. The results of univariate analysis showed that compared with non malignant group, the patients in malignant nodule group were younger, the longest diameter of nodule was smaller, TgAb level was higher, TSH level was higher, FT3 level was lower, the proportion of internal calcification was higher, thyroglobulin level was higher, CEA level was higher, calcitonin level was higher, and the proportion of abnormal lipid metabolism and glucose metabolism was also higher, which was statistically significant (P<0.05). Multivariate logistic regression analysis showed that TgAb positive, internal calcification, increased carcinoembryonic antigen level, dyslipidemia, elevated thyroglobulin level, and abnormal glucose metabolism, elevated calcitonin level were associated with the increased risk of node canceration, and increased total FT3 level was associated with the reduced risk of canceration (P<0.05). Conclusion TgAb positive, internal calcification, increased carcinoembryonic antigen level, small nodule diameter, abnormal blood lipids, elevated thyroglobulin level, low total FT3 level, abnormal glucose metabolism, and elevated calcitonin level are associated with the increased risk of malignant transformation of benign thyroid nodules, which should be paid attention to clinically.

Rapid and living guidelines are those developed in response to public health emergencies in a short period of time using a scientific and standardized approach. Subsequently， they provide timely and credible recommendations for decision makers through regular and frequent updates of clinical evidence and recommendations. In this paper， we introduced the definition of rapid and living guideline as well as analyzed the basic characteristics of eight rapid and living guidelines in the field of traditional Chinese medicine （TCM） published till 2023 June， summarizing three core methodological issues in relation to how to rapidly develop guidelines， how to formulate recommendations when there is lack of evidence， and how to ensure the timeliness of guidelines. Based on the analysis of current rapid and living guidelines， it is implicated that there is necessity to carry out rapid and living guideline in the field of TCM， and the methodology of rapid integration of multivariate evidence in the field of TCM needs to be further explored； furthermore， it is necessary to further explore the obstacles of implementation of guidelines and promote timely updating， all of which provide certain theoretical references for relevant guideline developers and researchers.

It is necessary to develop rapid and living guidelines in order to improve the evidence translation and guidance for clinical practice in emergency situations， and to enhance the participation of traditional Chinese medicine （TCM） in management of emergencies. This paper introduced the process of developing rapid and living guidelines of TCM and divided it into three stages， that is preparation， rapid development and dynamic updating， which highlights the features of rapid development， high quality， and dynamic updating and the integration with the predominance of TCM. By comparing with general guidelines on composition， personnel number， timing to formulate and communication patterns of the guideline working groups， as well as the content and number of clinical questions， this paper mainly gave suggestions on how to formulate a concise but authoritative team during the preparation stage， how to efficiently manage the guideline team and promote the development process from conflict of interest management， working and communication mode adjustment， and how to formulate and update the important and prioritized clinical questions， all of which may provide reference for the development of TCM rapid and living guidelines.

The lack of direct evidence is an important problem faced in the formation of recommendations in rapid living guidelines of traditional Chinese medicine under public health emergencies， and the supplementation of indirect evidence can be a key method to solve this problem. For the collection of evidence， the type of evidence required， including direct and indirect evidence， should be clarified， and ‘direct first’ principle for selecting evidence can be set to standardize and accelerate the guideline development. When integrating evidence， recommendations can be formed directly if there is sufficient direct evidence， while regarding insufficient direct evidence， recommendations need to be supplemented and improved by integrating indirect evidence. In addition， when the body of evidence contains evidence from multiple sources， it is suggested to rate the evidence according to “higher rather than lower” principle. Finally， when forming recommendations， the level of evidence， safety and economic efficiency should be taken into consideration to determine the strength of the recommendation.
