Huangqintang， with its accurate efficacy， is a classic formula specialized in treating dysentery recommended and promoted by medical experts from successive generations， and it was included in the Catalogue of Ancient Classic Prescriptions （the Second Batch， Han Chinese medicine prescriptions） published by the National Administration of Traditional Chinses Medicine （TCM） in 2023. The method of bibliometrics was applied in this study to conduct textual research on the classic formula Huangqintang and provide a literature reference for the development of modern preparations of Huangqintang. A total of 2 026 pieces of ancient literature were searched with "Huangqintang" as the key word， and 23 pieces of effective data were selected， involving 15 ancient TCM books. The historic evolution， composition， dosage， origin， processing methods， preparation and decocting methods， efficiency， and application of Huangqintang were carefully reviewed. The results showed that Huangqintang was first recorded in the Treatise on Febrile Diseases written by ZHANG Zhongjing. It has the effect of clearing heat， stopping dysentery， regulating the middle， and downbearing counterflow and has become one of the classic formulas widely used in clinical practice. Because of its accurate efficacy， medical experts from later generations have modified it from its original composition. Though many prescriptions have different names， it is the manifestation of physicians' inheritance and development of the thought of ZHANG Zhongjing. Ancient literature showed this prescription had wide indications yet centered on digestive system diseases such as dysentery and abdominal pain. Modern applications of Huangqintang involve digestive， respiratory， ophthalmology and otolaryngology， gynecological， skin， musculoskeletal system， and connective tissue， and this prescription has great potential in treating ulcerative colitis， diarrhea， acute enteritis， and damp-heat dysentery. Through a systematic textual excavation and review of the ancient literature about Huangqintang， the paper has confirmed its key information， so as to provide a scientific basis for the clinical application and new drug development of classic formulas.

The classic formula Fangji Fulingtang is from ZHANG Zhongjing's Synopsis of the Golden Chamber in the Eastern Han dynasty. It is composed of Stephaniae Tetrandrae Radix， Astragali Radix， Cinnamomi Ramulus， Poria， and Glycyrrhizae Radix et Rhizoma， with the effects of reinforcing Qi and invigorating spleen， warming Yang and promoting urination. By a review of ancient medical books， this paper summarizes the composition， original plants， processing， dosage， decocting methods， indications and other key information of Fangji Fulingtang， aiming to provide a literature basis for the research， development， and clinical application of preparations based on this formula. Synonyms of Fangji Fulingtang exist in ancient medical books， while the formula composition in the Synopsis of the Golden Chamber is more widespread and far-reaching. In this formula， Stephaniae Tetrandrae Radix， Astragali Radix， Cinnamomi Ramulus， Poria， and Glycyrrhizae Radix et Rhizoma are the dried root of Stephania tetrandra， the dried root of Astragalus embranaceus var. mongholicus， the dried shoot of Cinnamomum cassia， the dried sclerotium of Poria cocos， and the dried root and rhizome of Glycyrrhiza uralensis， respectively. Fangji Fulingtang is mainly produced into powder， with the dosage and decocting method used in the past dynasties basically following the original formula. Each bag is composed of Stephaniae Tetrandrae Radix 13.80 g， Astragali Radix 13.80 g， Cinnamomi Ramulus 13.80 g， Poria 27.60 g， and Glycyrrhizae Radix et Rhizoma 9.20 g. The raw materials are purified， decocted in water from 1 200 mL to 400 mL， and the decoction should be taken warm， 3 times a day. Fangji Fulingtang was originally designed for treating skin edema， and then it was used to treat impediment in the Qing dynasty. In modern times， it is mostly used to treat musculoskeletal and connective tissue diseases and circulatory system diseases， demonstrating definite effects on various types of edema and heart failure. This paper clarifies the inheritance of Fangji Fulingtang and reveals its key information （attached to the end of this paper）， aiming to provide a theoretical basis for the development of preparations based on this formula.

Objective:To investigate the iodine nutrition status of key population in Fuzhou City, and to provide scientific basis for adjusting intervention strategies.Methods:From March to October 2021, a survey was conducted on iodine nutrition status of key population in 12 counties (cities, districts) of Fuzhou City. Each county (city, district) was divided into 5 sampling areas according to the east, west, south, north and middle directions. One township (street) was selected from each area, and 40 non-boarding children aged 8 - 10 (age balanced, half male and half female) from one primary school and 20 pregnant women (early, middle and late pregnancy balanced) were selected as survey subjects. Household salt samples and random urine samples were collected, and the salt iodine and urine iodine levels were tested by direct titration and arsenic and cerium catalytic spectrophotometry, respectively. Children's thyroid volume was measured by B-ultrasonography. At the same time, in cooperation with Fuzhou Maternal and Child Health Hospital, the thyroid stimulating hormone (TSH) testing results of heel blood of full-term natural delivery newborns in Fuzhou City in 2021 were collected.Results:A total of 2 400 children were monitored for salt iodine, urine iodine and goiter. The median salt iodine was 24.40 mg/kg, with an iodine salt coverage rate of 93.04% (2 233/2 400), a qualified rate of iodized salt of 97.40% (2 175/2 233), and a consumption rate of qualified iodized salt of 90.62% (2 175/2 400). The median urine iodine was 181.47 μg/L. The rate of goiter was 1.04% (25/2 400). A total of 1 200 pregnant women were monitored for salt iodine and urine iodine. The median salt iodine was 24.10 mg/kg, the coverage rate of iodized salt was 91.08% (1 093/1 200), the qualified rate of iodized salt was 97.90% (1 070/1 093), and the consumption rate of qualified iodized salt was 89.17% (1 070/1 200). The median urine iodine was 128.10 μg/L. The median TSH level in the heel blood of 14 242 newborns was 3.38 mU/L, and the proportion of TSH level > 5 mU/L was 30.96% (4 410/14 242).Conclusions:In 2021, children in Fuzhou City are at an appropriate level of iodine, but pregnant women are insufficient of iodine. We should continue to maintain comprehensive prevention and control measures mainly based on salt iodization, provide health education for pregnant women, and strengthen monitoring of TSH level in newborns.

【Objective】 To investigate the anemia status of infants and toddlers aged 6 - 24 months in Linxia Hui Autonomous Prefecture, Gansu Province, and to comprehensively evaluate the differences in feeding behaviors between anaemic and normal children through the infant and child feeding index (ICFI) and feeding knowledge scores, so as to provide reference for the guidance of infants and young children feeding in ethnic minority areas and the promotion of children′s growth and development. 【Methods】 Taking infants and young children aged 6 - 24 months in Linxia Prefecture as the study subjects, a multi-stage random sampling method was used to select children who met the requirements from 5 townships and 5 villages in 7 counties in 2019 and 2020.Periphral blood samples were collected to test the level of hemoglobin, so as to determine the anemia status.Meanwhile, physical examination was performed and a questionnaire survey of guardians was conducted to analyze the association betweenanaemia and feeding patterns 【Results】 A total of 3 901 infants and children were included in this study, of whom 729 (18.70%) were anaemic, with a mean ICFI score of 12.56±2.70 and a mean feeding knowledge score of 1.97±1.01.There was no statistically significant association of low feeding knowledge score and low ICFI with anaemia after adjusting for confounders (P>0.05), Unqualified meat addition in ICFI was a risk factor for anaemia (OR=1.355, P=0.042), while non-bottle feeding in the past 24 hours (OR=0.762, P=0.021), and breastfeeding in the past 24 hours of infants and toddlers aged 12 - 24 months (OR=0.228, P=0.018) were protective factor for anemia in infants and toddlers aged 12 - 24 months. 【Conclusions】 The average prevalence of anemia in infants and toddlers aged 6 - 24 months in Linxia Hui Autonomous Prefecture of Gansu Province is high, but the level of infant feeding and the level of feeding knowledge of caregivers are low.Early adherence to breastfeeding, timely addition of supplementary food, and more comsumpution of meat for children are conducive to preventing anemia.

Prostate cancer is one of the most common malignant tumors in men and posing a serious threat to men's health. Detection methods such as prostate-specific antigen (PSA), prostate biopsy, and magnetic resonance imaging are widely used for prostate cancer screening, but they have low specificity, high cost, and significant risks. Therefore, there is an urgent need to develop highly specific, low-cost, easily obtained, stable, and reliable biomarkers, and use them as the basis to establish non-invasive screening and diagnostic methods for prostate cancer. This paper reviewed the recent advances in the use of prostate cancer biomarkers and combined detection methods for prostate cancer diagnosis and prognosis assessment and provides an in-depth analysis and comparison of different biomarkers and combined detection methods, as well as points out the directions and challenges for future research. The paper emphasizes the importance of developing efficient, cost-effective and easy-to-implement biomarkers to increase the early diagnosis rate of prostate cancer, improve patient prognosis, and reduce the waste of healthcare resources. This paper provides an important theoretical basis and technical guidance for early diagnosis, precise treatment and prognostic evaluation of prostate cancer, and has important reference value for promoting clinical research and practice of prostate cancer.

Objective:To learn about the implementation of various prevention and control measures after achieving the stage goal of eliminating iodine deficiency disorders (IDD) in Fuzhou City, and to evaluate the prevention and control effect.Methods:In September 2020, an assessment and evaluation was conducted on elimination of IDD in 12 counties (cities, districts) under the jurisdiction of Fuzhou City, with specific reference to the "Evaluation Content and Judgment Standards for Elimination of Iodine Deficiency Disorders" (2019 version). Using the target evaluation table for eliminating IDD, 4 management indicators of organizational and leadership, monitoring and prevention measures, iodized salt management and health education in 12 counties (cities, districts) from 2016 to 2020 were evaluated. Using stratified random sampling method, 2 townships/streets were selected from each county (city, district), and 20 pregnant women were sampled from each township/street. At the same time, two villages (neighborhood committees) were randomly selected from each township/street, and 20 children aged 8 - 10 (age balanced, half male and half female) were randomly selected from each village (neighborhood committee). The edible salt samples and instant urine samples of children and pregnant women were collected to detect the contents of salt iodine and urinary iodine; the iodine supplementation status of pregnant women was investigated by iodine supplementation rate questionnaire; the goiter in children was measured by B-ultrasound.Results:The management indicators scores of all 12 counties (cities, districts) were > 85 points, with an average score of 92.75 points. Changle District had the highest score (98 points), and Taijiang District had the lowest score (90 points). A total of 1 457 household salt samples were collected and tested in the city, including 967 samples from children aged 8 - 10 and 490 samples from pregnant women. The median salt iodine was 24.24 mg/kg, and the coverage rate of iodized salt was 93.62% (1 364/1 457). The qualified rate of iodized salt was 97.80% (1 334/1 364), and the coverage rate of qualified iodized salt was 91.56% (1 334/1 457). Except for Gulou District (88.33%, 106/120), Taijiang District (85.00%, 102/120), Mawei District (86.67%, 104/120), Changle District (89.34%, 109/122) and Minqing County (88.43%, 107/121), the coverage rate of qualified iodized salt was < 90%, the coverage rate of qualified iodized salt in the remaining counties (cities, districts) was > 90%. A total of 967 urine samples were collected from children, the median urinary iodine was 187.80 μg/L. The median urinary iodine of children in all counties (cities, districts) ranged from 140.08 to 269.70 μg/L. A total of 967 children were examined, and the goiter rate was 0.72% (7/967). The goiter rate ranged from 0 to 2.44% in all counties (cities, districts). A total of 490 urine samples were collected from pregnant women, with a median urinary iodine of 148.48 μg/L. Among them, the median urinary iodine of pregnant women in Gulou District (184.23 μg/L), Mawei District (262.85 μg/L), Jin'an District (176.80 μg/L), Luoyuan County (166.60 μg/L) and Yongtai County (157.62 μg/L) was > 150 μg/L, the median urinary iodine of pregnant women in other counties (cities, districts) was between 100 and 150 μg/L. A total of 490 pregnant women were investigated for iodine supplementation, the iodine supplementation rate was 94.90% (465/490). Except for Gulou District (85.00%, 34/40), Cangshan District (85.00%, 34/40) and Lianjiang County (87.50%, 35/40), the iodine supplementation rate < 90%, the iodine supplementation rate of pregnant women in other counties (cities, districts) was > 90%.Conclusions:The IDD prevention and control measures in Fuzhou City have been well implemented, and all counties (cities, districts) in Fuzhou City have maintained the state of eliminating IDD, and continued to consolidate the prevention and control achievements.

ObjectiveTo investigate the role of cyclic adenosine monophosphate （cAMP）/protein kinase A （PKA）/cAMP-response element binding protein （CREB） signaling pathway in water metabolism and intestinal epithelial permeability in ulcerative colitis （UC） and the intervention mechanism of Shaoyaotang based on the theory of large intestine governing fluids. MethodSixty male SD rats were divided into blank group， model group， mesalazine group （0.42 g·kg^-1）， Shaoyaotang low-dose group （11.1 g·kg^-1）， Shaoyaotang medium-dose group （22.2 g·kg^-1） and Shaoyaotang high-dose group （44.4 g·kg^-1）， with 10 in each group. The UC rat model of internal retention of dampness-heat was established by compound factors. The blank group and the model group were given normal saline （ig）. The mesalazine group was given mesalazine （ig）， and Shaoyaotang low-， medium- and high-dose groups were administrated with corresponding doses of Shaoyaotang （ig）. The treatment lasted for 14 days. The diarrhea score and fecal moisture content of rats in each group were observed. The contents of diamine oxidase （DAO） and D-lactic acid in plasma were detected by enzyme-linked immunosorbent assay （ELISA）. The protein expressions of aquaporin （AQP）8， AQP4， ZO-1 and Occludin in colon tissues were detected by immunohistochemistry， while those of cAMP， PKA and CREB in colon tissues were determined by Western blot. ResultCompared with the normal group， the model group had elevated diarrhea score and fecal moisten content （P<0.01）， increased contents of DAO and D-lactic acid in plasma （P<0.01） and decreased protein expressions of ZO-1， Occludin， AQP8， AQP4， cAMP， PKA and CREB in colon （P<0.01）. Compared with the conditions in the model group， the contents of DAO and D-lactic acid in plasma in each administration groups were lower （P<0.01）， while the protein expressions of ZO-1， Occludin， AQP8， AQP4， cAMP， PKA and CREB in colon were higher （P<0.01）. ConclusionShaoyaotang alleviates the diarrhea in UC， probably through activating cAMP/PKA/CREB signaling pathway， up-regulating expressions of AQPs， enhancing tight junctions in intestinal epithelium and thus improving the water metabolism in colon and the intestinal mucosal permeability.

This study aims to investigate the effect of transmembrane protein angiotensin converting enzyme 2 (ACE2) on the prognosis of breast cancer and its potential mechanism.Public databases were used to analyze ACE2 expression and its relationship with clinicopathological features and prognosis of breast cancer patients, combined with in vitro experiments to analyze the mechanism of action and immune relevance of ACE2 in breast cancer.Results showed that the expression of ACE2 in breast cancer tissues was significantly lower than that in normal breast tissues, and that its expression was negatively correlated with age, M stage and N1mi stage of breast cancer patients (P < 0.05).Patients with Luminal type breast cancer with high ACE2 expression had poor prognosis, while in the triple-negative breast cancer (TNBC) subtype, ACE2 showed different prognostic significance.In addition, ACE2 is closely associated with the metabolic and immune microenvironment of tumor tissue.In vitro experiments have shown that ACE2 is lowly expressed in MDA-MB-231 cells and may inhibit cell progress by downregulating matrix metalloproteinase 2（MMP2）.The results suggest that the low expression of ACE2 in breast cancer is closely associated with patient prognosis as well as metabolic and immune microenvironment, and that ACE2 may inhibit TNBC cell progress through the MMP2 pathway.

Objective    To analyze prognostic ability of inflammation-based Glasgow prognostic score (GPS) in patients with ST-segment elevation myocardial infarction (STEMI). Methods    We retrospectively analyzed the clinical data of 289 patients with STEMI admitted to the Department of Emergency in West China Hospital from April 2015 to January 2016. All study subjects were divided into three groups: a group of GPS 0 (190 patients including 150 males and 40 females aged 62.63±12.98 years), a group of GPS 1 (78 patients including 58 males and 20 females aged 66.57±15.25 years), and a group of GPS 2 (21 patients including 16 males and 5 females aged 70.95±9.58 years). Cox regression analysis was conducted to analyze the independent risk factors of predicting long-term mortality of patients with STEMI. Results    There was a statistical difference in long-term mortality (9.5% vs. 23.1% vs. 61.9%, P<0.001) and in-hospital mortality (3.7% vs. 7.7% vs. 23.8%, P<0.001) among the three groups. The Global Registry of Acute Coronary Events (GRACE) scores and Gensini scores increased in patients with higher GPS scores, and the differences were statistically different (P<0.001). Multivariable Cox regression analysis showed that the GPS was independently associated with STEMI long-term all-cause mortality (1 vs. 0, HR: 2.212, P=0.037; 2 vs. 0, HR: 8.286, P<0.001). Conclusion    GPS score is helpful in predicting the long-term and in-hospital prognosis of STEMI patients, and thus may guide clinical precise intervention by early risk stratification.
