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 prescription Mahuang Shengmatang in the Treatise on Cold Damage （《伤寒论》） has sparked considerable debate among medical practitioners throughout history， with varying opinions on its indications， pathogenesis described in the text， principle of compatibility， and clinical applications. Both ancient and modern interpreters of Mahuang Shengmatang often focus on herbal compatibility as a primary approach to deduce the pathogenesis and treatment methods. Building upon this foundation， this paper utilizes herbal dosage as a clue to discern the primary and secondary herbs in the prescription. It further analyzes the principle of compatibility based on herbal indications， summarizing the indications and therapeutic principles of this prescription. Ultimately， it reveals the underlying pathogenesis reflected in the text. The internal closure of heat and toxin leads to the stagnation of Qi， preventing Yang Qi from reaching the extremities and causing cold hands and feet. When the pathogenic Qi finds no outlet， it floods both the upper and lower regions of the body， attacking the throat and causing cough with expectoration of pus and blood， and descending to the large intestine to consume Yin fluids， resulting in persistent diarrhea. Based on this pathogenesis， the paper expands the scope of symptoms and signs associated with the prescription， providing a more detailed portrayal of the applicable patient population and enhancing the basis for clinical prescription references. Additionally， the paper presents considerations on several controversial topics， suggesting that the "lower pulse" described in the text refers to the lower limb arterial pulsation， and the symptoms and signs resemble those of septic shock in modern medicine. Therefore， Mahuang Shengmatang should be categorized as a prescription for treating warm diseases and it is not developed by ZHANG Zhongjing. By employing a detailed discussion on the syndrome， pathogenesis， and clinical application in the texts of Mahuang Shengmatang from the dosage， principle of compatibility， and herbal indications， this paper not only enriches the theoretical foundation of Mahuang Shengmatang but also provides a comprehensive perspective and fresh ideas for understanding its clinical application.

OBJECTIVE To investigate the use of drugs and the development of pharmaceutical care in the tight medical alliance （shorted for “medical alliance”） of Wanzhou District of Chongqing， and provide reference for the further construction of the medical alliance. METHODS A survey form was designed and distributed to 21 constituent units （5 leading units and 16 member units） of 5 medical alliances in Wanzhou District of Chongqing. The statistical analysis was conducted in aspects of basic drug allocation and use， pharmaceutical personnel team construction， the development of pharmaceutical care， and rational use of antibiotics. RESULTS Among the 21 constituent units， 4 leading units and 14 member units achieved the target for the proportion of essential drug procurement varieties， with a total compliance rate of 85.71%； 4 leading units and 13 member units achieved the target for the proportion of national essential drug allocation and usage amount， with a total compliance rate of 80.95%. The proportions of personnel with doctoral degrees in the 5 leading units and 16 member units were 1.71% and 0 respectively， and the proportions of personnel with senior professional titles were 8.56% and 1.63%， respectively. A total of 5 pharmacy or pharmaceutical combined outpatient clinics were set up in the 21 medical alliance units， and 5 clinical pharmacy information service platforms were established； all 5 leading units were able to regularly carry out clinical pharmacy projects， while only 4 out of 16 member units had conducted medical order review and evaluation. The proportions of irrational use of antibiotics in outpatient prescriptions and inpatient medical records of the 16 member units （4.81%， 5.21%） were significantly higher than those of the 5 leading units （2.80%， 4.00%）. CONCLUSIONS The allocation and usage of national essential drugs in 21 constituent units from Wanzhou District of Chongqing are both in good standing. However， the data on the allocation of pharmaceutical professionals and the number， qualifications， and job titles of clinical pharmacists in member units are generally low. Moreover， the pharmaceutical service projects and service quality in member units need to be further improved.

ObjectiveTo investigate the effects of the combination of components from Tripterygii Radix et Rhizoma and Chuanxiong Rhizoma on rheumatoid arthritis fibroblast-like synoviocytes （RA-FLSs） and the underlying mechanism. MethodsRA-FLSs were grouped as follows： blank control， positive control （methotrexate）， Tripterygii Radix et Rhizoma components， Chuanxiong Rhizoma components， and components from Tripterygii Radix et Rhizoma+Chuanxiong Rhizoma. The cell-counting kit-8 （CCK-8） assay was employed to the cell proliferation， invasion， and apoptosis. The levels of tumor necrosis factor （TNF）-α， interleukin （IL）-6， reactive oxygen species （ROS）， and malondiadehyde （MDA） in cells were measured. Western blot was employed to determine the protein levels of nuclear factor erythroid 2-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， nuclear factor-kappa B （NF-κB） p65， phosphorylated inhibitory subunit of NF-κBα （p-IκBα）， cysteinyl aspartate-specific protease-3 （Caspase-3）， and B-cell lymphoma 2 （Bcl-2）. Real-time PCR was employed to determine the mRNA levels of Nrf2， HO-1， and NF-κB p65. ResultsThe cells in the groups of positive control， Tripterygii Radix et Rhizoma components， Chuanxiong Rhizoma components， and components from Tripterygii Radix et Rhizoma+Chuanxiong Rhizoma were treated with 2.50 mg·L^-1 methotrexate， 0.20 mg·L^-1 triptolide + 0.20 mg·L^-1 celastrol， 5.00 mg·L^-1 ferulic acid + 20.00 mg·L^-1 ligustrazine， 0.20 mg·L^-1 triptolide + 0.20 mg·L^-1 celastrol + 5.00 mg·L^-1 ferulic acid + 20.00 mg·L^-1 ligustrazine， respectively. Compared with the blank control group， drug administration reduced the proliferation and invasion and increased the apoptosis of cells （P<0.01）， lowered the levels of TNF-α， IL-6， ROS， and MDA （P<0.01）， up-regulated the mRNA and protein levels of Caspase-3， Nrf2， and HO-1 （P<0.01）， and down-regulated the mRNA and protein levels of Bcl-2， NF-κB p65， and p-IκBα （P<0.01）. Compared with the Tripterygii Radix et Rhizoma components group， the combination of components from Tripterygii Radix et Rhizoma+Chuanxiong Rhizoma inhibited the proliferation and invasion （P<0.05） and promoted the apoptosis of RA-FLSs， up-regulated the mRNA levels of Nrf2 and HO-1 and protein levels of Nrf2 and Caspase-3 （P<0.05）， and down-regulated the protein levels of NF-κB p65 and p-IκBα （P<0.05）. ConclusionThe combination of components from Chuanxiong Rhizoma and Tripterygii Radix et Rhizoma can inhibit the proliferation and invasion and promote the apoptosis of RA-FLSs and alleviate oxidative stress and inflammation by inhibiting the NF-κB signaling pathway， activating the Nrf2/HO-1 pathway， and regulating the expression of Bcl-2/Caspase-3.

OBJECTIVE To establish a multi-index quantitative detection method， and to evaluate the quality difference of Gleditsia sinensis from different producing areas. METHODS The contents of protocatechuic acid， vanillic acid， isoscopoletin， scoparone， isovitexin， fustin， taxifolin， fisetin， quercetin， kaempferol， echinocystic acid， betulinic acid， β -sitosterol and stigmasterol were detected by high performance liquid chromatography-quantitative analysis of multi-components by single marker （HPLC-QAMS）. The chromatographic column was Kromasil C18， the mobile phase was 0.2% phosphoric acid-acetonitrile solution （gradient elution）， the detection wavelengths were 254， 360， 210 nm for different index components， the column temperature was 30 ℃ ， the flow rate was 1.0 mL/min， and the sample injection volume was 10 μL. The contents of extract and total ash were detected according to the method of Chinese Pharmacopoeia. The quality differences of 30 batches of G. sinensis （No. S1-S30） from different producing areas were evaluated by chemometrics， weighted technique for order preference by similarity to an ideal solution （TOPSIS） analysis and Logistic regression model. RESULTS The linear ranges of 14 components were 1.55-77.50， 0.71- 35.50， 0.28-14.00， 0.96-48.00， 1.77-88.50， 0.09-4.50， 4.65-232.50， 1.49-74.50， 0.37-18.50， 1.18-59.00， 7.35-367.50， 3.58- 179.00， 0.49-24.50 and 0.21-10.50 μg/mL， respectively （all r＞0.999）. The RSDs of precision， stability （24 h） and repeatability were less than 2.00%； the average recoveries were 96.99%-100.13% （all RSDs＜2.00%）， and the relative correction factor had good repeatability. The contents of extract and total ash were Δ 基金项目 湖北省中医药科研立项青年人才项目 （No. 4.2%-12.5% and 0.5%-2.3%， respectively. There was no ZY2019Q014） significant difference in the content of 14 components measured by QAMS method and external standard method （P＞0.05）. The results of chemometrics showed that 30 batches of samples were clustered into 3 categories： S1 to S11 form one category， S12 to S20 form another category， and S21 to S30 constitute the third category. Echinocystic acid， betulinic acid， taxifolin， kaempferol， isovitexin， scoparone and protocatechuic acid may be the differential components affecting the quality of G. sinensis from different producing areas. The analysis results of the weighted TOPSIS method revealed that relative closeness （Jb） for 30 batches of G. sinensis ranged from 0.144 5 to 0.721 8， with S27 achieving the highest value （Jb） of 0.721 8. The analysis results of the Logistic regression model showed that S21-S30 batches of samples were of superior grade， S1-S11 were of intermediate grade， and S12-S20 were of inferior grade. CONCLUSIONS The established HPLC-QAMS method is simple and accurate. The comprehensive evaluation method is objective and comprehensive， and can be used to evaluate the quality difference of G. sinensis from different producing areas.

Aromatic Chinese medicinal essential oils are volatile oils extracted from aromatic Chinese herbs， which can prevent and treat respiratory infectious diseases through multiple synergistic mechanisms including pathogen inhibition， immune regulation， and inflammatory response regulation. Essential oils are primarily used externally on the body to prevent infections and alleviate symptoms through methods like inhalation， smearing， topical application， bathing， gargling or as a suppository. They can also be utilized in the environment for disinfection and air purification， through methods like diffusion， vaporization， or spraying. The external application of essential oils extracted from Chinese aromatic herbs has the advantages of convenience， quick absorption， and simultaneous influence on both the body and mind. However， there are still challenges and deficiencies in aspects such as the positioning of functions， indications， safety， and the research on the mechanism of action. It has been proposed to combine the theory of aromatic Chinese medicinals with the characteristics of essential oils， and formulate prescriptions of Chinese medicinal essential oils under the principles of traditional Chinese medicine syndrome differentiation， and prevent and treat respiratory infectious diseases efficiently， accurately， and safely， thereby expanding the clinical application of aromatic Chinese medicinals and the preventive theory of traditional Chinese medicine.

The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."

OBJECTIVE To prepare reactive oxygen species （ROS）-responsive methotrexate （MTX）-modified paclitaxel （PTX）/icariin （ICA） micelles （MTX-oxi-Ms@PTX/ICA）， and perform technology optimization and in vitro anti-tumor effect evaluation. METHODS Synergistic toxicity concentration range of PTX and ICA was screened by synergistic toxicity test. The micelles were prepared by thin film hydration method， and their technology was optimized by response surface methodology. The fundamental characteristics of the micelles prepared by the optimal technology were evaluated. The micelles’ cytotoxicity， targeting ability to renal carcinoma RENCA cells of mice， and their inhibitory effects on invasion and migration were assessed. RESULTS Results of synergistic toxicity experiments demonstrated that the strongest synergistic effect occurred when PTX concentrations ranged from 2.5 to 10 μmol/L and ICA concentrations ranged from 5 to 15 μmol/L. The optimal technology of MTX-oxi-Ms@PTX/ ICA was determined to include 80 mg Soluplus®， Soluplus® and TPGS1000 mass ratio of 4∶1 （mg/mg）， 2 mg DSPE-PEG2000-TK- PEG5000， 2 mg DSPE-PEG2000-MTX， 1 mg PTX， and 1.5 mg ICA， with a hydration temperature of 35 ℃ and a formulation volume of 5 mL. Under the optimal conditions， average encapsulation efficiency of PTX and ICA in 3 batches of MTX-oxi- Ms@PTX/ICA reached 92.75%， the critical micelle concentration （CMC） was 0.007 9 mg/mL， the particle size was （62.09±1.68） nm， the polydispersity index （PDI） was 0.046±0.032， and the Zeta potential was （－2.47±0.15） mV. Within 30 days of placement， there was no significant change E-mail：yingqiang_1126@163.com in particle size and polydispersity index of micelle. In vitro release experiments showed that MTX-oxi-Ms@PTX/ICA released drugs more rapidly in oxidative environments. The half maximal inhibitory concentration of MTX-oxi-Ms@PTX/ICA against RENCA cells was （5.170±0.036） μmol/L. In vitro cellular uptake experiments indicated that compared with unmodified micelles， MTX modified micelles had stronger targeting effects on cancer cells， and also significantly enhanced the inhibitory ability of invasion and migration of RENCA cells （P＜0.05）. CONCLUSIONS MTX-oxi-Ms@PTX/ICA micelles are successfully prepared， which exhibit high encapsulation efficiency， low critical micelle concentration， and good stability. These micelles demonstrate significant cytotoxicity against RENCA cells and effectively inhibit cancer cell invasion and migration.

Objective To compare the mid- and long-term clinical results of mitral valve plasty (MVP) and mitral valve replacement (MVR) in the treatment of functional mitral regurgitation (FMR). Methods Patients with FMR who underwent surgical treatment in the Department of Cardiovascular Surgery of the General Hospital of Northern Theater Command from 2012 to 2021 were collected. The patients who underwent MVP were divided into a MVP group, and those who underwent MVR into a MVR group. The clinical data and mid-term follow-up efficacy of two groups were compared. Results Finally 236 patients were included. There were 100 patients in the MVP group, including 53 males and 47 females, with an average age of (61.80±8.03) years. There were 136 patients in the MVR group, including 72 males and 64 females, with an average age of (61.29±8.97) years. There was no statistical difference in baseline data between the two groups (P＞0.05). There was no statistical difference between the two groups in the extracorporeal circulation time, aortic occlusion time, postoperative hospital and ICU stay, intraoperative blood loss, or hospitalization death (P＞0.05), but the time of mechanical ventilation in the MVP group was significantly shorter than that in the MVR group (P=0.022). The total follow-up rate was 100.0%, the longest follow-up was 10 years, and the average follow-up time was (3.60±2.55) years. There were statistical differences in the left atrial diameter, left ventricular end-diastolic diameter, left ventricular end-systolic diameter and cardiac function between the two groups compared with those before surgery (P<0.05). The postoperative left ventricular ejection fraction in the MVP group was statistically higher than that before surgery (P=0.002), but there was no statistical difference in the MVR group before and after surgery (P=0.658). The left atrial diameter in the MVP group was reduced compared with the MVR group (P=0.026). The recurrence rate of mitral regurgitation in the MVP group was higher than that in the MVR group, and the difference was statistically significant (10.0% vs. 1.5%, P=0.003). There were 14 deaths in the MVP group and 19 in the MVR group. The cumulative survival rate (P=0.605) and cardiovascular events-free survival rate (P=0.875) were not statistically significant between the two groups by Kaplan-Meier survival analysis. Conclusion The safety, and mid- and long-term clinical efficacy of MVP in the treatment of FMR patients are better than MVR, and the left atrial and left ventricular diameters are statistically reduced, and cardiac function is statistically improved. However, the surgeon needs to be well aware of the indications for the MVP procedure to reduce the rate of mitral regurgitation recurrence.

ObjectiveTo investigate the influence of entecavir （ETV） versus tenofovir alafenamide fumarate （TAF） on renal function in previously untreated patients with chronic hepatitis B （CHB）. MethodsA retrospective analysis was performed for the clinical data of 167 previously untreated CHB patients who received ETV or TAF treatment for at least 48 weeks at the outpatient service of Department of Infectious Diseases in The First Affiliated Hospital of Nanchang University from September 2019 to November 2023， and according to the antiviral drug used， they were divided into ETV group with 117 patients and TAF group with 50 patients. In order to balance baseline clinical data， propensity score matching （PSM） was used for matching and analysis at a ratio of 2∶1， and the two groups were compared in terms of estimated glomerular filtration rate （eGFR） and the incidence rate of abnormal renal function at week 48. According to eGFR at week 48， the patients were divided into normal renal function group and abnormal renal function group. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The multivariate Logistic regression analysis was used to investigate the influencing factors for abnormal renal function， and the receiver operating characteristic （ROC） curve was used to assess the performance of each indicator in predicting abnormal renal function. The Kaplan-Meier method was used to analyze the cumulative incidence rate of abnormal renal function， and the log-rank test was used for comparison. The analysis of variance with repeated measures was used to compare the dynamic changes of eGFR during antiviral therapy in CHB patients. ResultsAfter PSM matching， there were 100 patients in the ETV group and 50 patients in the TAF group. There were no significant differences in baseline clinical data between the ETV group and the TAF group （all P>0.05）， with an eGFR level of 112.29±9.92 mL/min/1.73 m² in the ETV group and 114.72±12.15 mL/min/1.73 m² in the TAF group. There was a reduction in eGFR from baseline to week 48 in both groups， and compared with the TAF group at week 48， the ETV group had a significantly lower eGFR （106.42±14.12 mL/min/1.73 m² vs 112.25±13.44 mL/min/1.73 m²， t=-2.422， P=0.017） and a significantly higher incidence rate of abnormal renal function （17.00% vs 4.00%， χ²=5.092， P=0.024）. After the patients were divided into normal renal function group with 131 patients and abnormal renal function group with 19 patients， the univariate analysis showed that there were significant differences between the two groups in age （Z=-2.039， P=0.041）， treatment drug （ETV/TAF） （χ²=5.092， P=0.024）， and baseline eGFR level （t=4.023， P<0.001）， and the multivariate Logistic regression analysis showed that baseline eGFR （odds ratio ［OR］=0.896， 95% confidence interval ［CI］： 0.841 — 0.955， P<0.001） and treatment drug （OR=5.589， 95%CI： 1.136 — 27.492， P=0.034） were independent influencing factors for abnormal renal function. Baseline eGFR had an area under the ROC curve of 0.781 in predicting abnormal renal function in CHB patients， with a cut-off value of 105.24 mL/min/1.73 m²， a sensitivity of 73.68%， and a specificity of 82.44%. The Kaplan-Meier curve analysis showed that the patients with baseline eGFR≤105.24 mL/min/1.73 m² had a significantly higher cumulative incidence rate of abnormal renal function than those with baseline eGFR>105.24 mL/min/1.73 m² （χ²=22.330， P<0.001）， and the ETV group had a significantly higher cumulative incidence rate of abnormal renal function than the TAF group （χ²=4.961， P=0.026）. With the initiation of antiviral therapy， both the ETV group and the TAF group had a significant reduction in eGFR （F=5.259， P<0.001）， but the ETV group only had a significant lower level of eGFR than the TAF group at week 48 （t=-2.422， P=0.017）； both the baseline eGFR≤105.24 mL/min/1.73 m² group and the baseline eGFR>105.24 mL/min/1.73 m² group had a significant reduction in eGFR （F=5.712， P<0.001）， and there was a significant difference in eGFR between the two groups at baseline and weeks 12， 24， 36， and 48 （t=-13.927， -9.780， -8.835， -9.489， and -8.953， all P<0.001）. ConclusionFor CHB patients initially treated with ETV or TAF， ETV antiviral therapy has a higher risk of renal injury than TAF therapy at week 48.
