As an exclusive Miao medicine of Honwing Pharma （Guizhou） Co. Ltd.， Yifei Zhike capsules are both a prescription drug and an over-the-counter （OTC） drug. Its main ingredients include Ranunculus ternatus and Panax notoginseng. With the effects of nourishing Yin and moistening the lungs， as well as relieving cough and reducing phlegm， Yifei Zhike capsules are often used in the treatment of acute and chronic bronchitis， pulmonary tuberculosis， and other diseases. However， there is insufficient understanding of their efficacy， suitable syndromes， and safety in clinical practice， with a lack of relevant expert consensus on clinical application. To standardize their clinical application， 30 experts from the fields of respiratory medicine， pharmacy， and evidence-based medicine were invited to develop an Expert Consensus on the Clinical Application of Yifei Zhike Capsules （Consensus for short） through evidence-based medicine methods. The Consensus clarified the syndrome characteristics， disease stages， dosages， treatment courses， combined medication， and other norms in the treatment of acute/chronic bronchitis and pulmonary tuberculosis and could be applicable to clinical physicians and pharmacists in medical and health institutions at all levels. In disease diagnosis， it provided diagnostic criteria for traditional Chinese medicine and Western medicine and clarified that the suitable traditional Chinese medicine syndrome was the syndrome of Qi-Yin deficiency with intermingled phlegm-blood stasis. Clinical studies have confirmed that Yifei Zhike capsules combined with standard anti-tuberculosis therapy can effectively improve the symptoms of pulmonary tuberculosis patients， increase the sputum smear conversion rate， and promote the absorption of lesions. When treating acute cough caused by respiratory tract infections， Yifei Zhike capsules can increase the markedly effective rate and the seven-day disappearance rate of cough symptoms. Meanwhile， recommendations for specific usage， dosages， and treatment courses were given for different diseases， and it was pointed out that long-term medication required key monitoring of adverse reactions. In safety， the adverse reactions of Yifei Zhike capsules involved multiple aspects such as the digestive system and allergic reactions， and pregnant women and women during menstruation were prohibited from using it. In addition， modern research has shown that Yifei Zhike capsules have an adjuvant therapeutic effect on tuberculous pleurisy and may be effective for inflammatory and benign pulmonary nodules. However， further research should be conducted on the toxicological safety of long-term medication. The formulation of the Consensus provides a scientific basis for the rational clinical application of Yifei Zhike capsules， which helps to improve clinical efficacy and reduce medication risks.

The compilation instructions for the Expert Consensus on Clinical Application of Yifei Zhike Capsules systematically expound the development background， methodological framework， and core achievements of this consensus. In view of the problems existing in the clinical application of Yifei Zhike Capsules， such as insufficient efficacy evidence and lack of standardized syndrome differentiation， the Institute of Basic Research in Clinical Medicine， China Academy of Chinese Medical Sciences took the lead and collaborated with 21 tertiary grade-A hospitals and research institutions across China to form a multidisciplinary expert group （comprising 30 experts in clinical medicine， pharmacy， and methodology）. The compilation work was carried out in strict accordance with the World Health Organization （WHO） guidelines， the GB/T 1.1-2020 standard， and the writing specifications for the explanatory notes of expert consensus on clinical application of Chinese patent medicines. Through systematic literature retrieval （including 32 studies， with 24 clinical studies）， Grading of Recommendations Assessment， Development and Evaluations （GRADE）-based evidence grading， and multiple rounds of discussions using the nominal group method （25 experts voted to determine 17 clinical questions）， 5 evidence-based recommendations and 11 expert consensus suggestions were formed. It is clarified that this medicine （Yifei Zhike Capsules） is applicable to the treatment of expectoration/hemoptysis in acute and chronic bronchitis and the adjuvant treatment of pulmonary tuberculosis. It is recommended that it can be used alone or in combination with anti-tuberculosis drugs. The safety evaluation shows that this medicine mainly induces the following adverse reactions： mild gastrointestinal reactions （such as nausea and abdominal pain） and rashes. The contraindicated populations include pregnant women and women during menstruation. The compilation process of the consensus underwent three rounds of expert letter reviews， two rounds of peer reviews， and quality control assessments to ensure methodological rigor and clinical applicability. In addition， through policy alignment， academic promotion， and a dynamic revision mechanism， the standardization of clinical application was promoted， providing a demonstration for the evidence-based transformation of characteristic therapies of Miao medicine.

Objective To explore risk factors for cardiac valve calcification (CVC) in maintenance hemodialysis (MHD) patients and evaluate its impact on cardiovascular events and mortality. Methods Retrospective selection of 223 patients with MHD admitted to the Department of Nephrology of Jinshan Hospital, Fudan University from June 30, 2019 to June 30, 2024, and enrollment completed within one week of June 30, 2019. Patients were divided into CVC and non-CVC groups. Baseline data and 5-year follow-up data were collected. The binary logistic regression analysis was performed to explore the risk factors for CVC. Kaplan-Meier survival curve was used to analyze the survival rate of patients. Cox proportional hazard regression model was applied to evaluate the impact of CVC on the survival rates of MHD patients. Results Totally, 223 MHD patients with an average age of (58.4±13.5) years and an average dialysis duration of (64.0±55.4) months were involved. Among them, 136(61.0%) were males, 117(52.5%) were complicated with CVC. Age, dialysis duration, diabetic kidney disease (DKD), the serum corrected total calcium and phosphate, intact parathyroid hormone (iPTH), high-sensitive C-reactive protein (hsCRP), and homocysteine (Hcy) were independent related factors for CVC (P＜0.05). Both all-cause mortality (46.6% vs 28.7%) and cardiovascular mortality (33.3% vs 16.0%) were significantly higher in the CVC group than those in the non-CVC group (P＜0.01). Conclusions Age, dialysis duration, the primary disease, calcium and phosphate, and inflammation- and nutrition-related serum indicators are associated with CVC in MHD patients. CVC significantly increases mortality risk of MHD patients.

Objective To explore the effect and mechanism of berberine combined with curcumin on ath-erosclerosis(AS)by mediating M1 macrophages polarization.Methods M1-type macrophages were obtained from mouse mononuclear macrophages(RAW264.7)induced by lipopolysaccharide(LPS,100 ng/mL)and interferon(IFN)-γ(20 ng/mL).A cell model was established.The cells were divided into a control group,model group,berberine group,curcumin group and berberine plus curcumin group.Concentrations of berberine and curcumin were detected by CCK-8 assay.The expression levels of M1-type macrophage markers iNOS,TNF-α,CXCL9 and p-STAT6/STAT6 in macrophage supernatant were detected by ELISA.Levels of iNOS,TNF-α and CXCL9 mRNA were detected by RT-PCR.Levels of iNOS,STAT6 and p-STAT6 proteins in each group were detected by Western blot.After down-regulation of STAT6 level by siRNA technology,expression of p-STAT6 protein was detected by Western blot.Expression levels of iNOS,TNF-α,CXCL9 and p-STAT6 were detected by ELISA.Results In the polarization of M1 macrophages induced by LPS and IFN-γ,berberine(25 μmol/L)and curcumin(20 μmol/L)were the best concentrations as compared with other drug concentration groups,and neither alone nor combined use could significantly inhibit the viability of RAW264.7 cells(P<0.05).As compared with the normal group,iNOS,TNF-α and CXCL9 mRNA and protein levels were increased in the model group,while P-STAT6/STAT6 levels were decreased,with statistical differences(P<0.05).As compared with the model group,iNOS,TNF-α and CXCL9 mRNA and protein levels in the berberine group,curcumin group,and berberine plus curcumin group were decreased,while P-STAT6/STAT6 levels were increased,and the changes were more obvious in berberine plus curcumin group,with statistical difference(P<0.05).After transfection of STAT6 siRNA in M1 macrophages in the berberine plus curcumin group,P-STAT6 levels were down-regulated,while expressions of iNOS,TNF-α and CXCL9 were up-regulated,with statistical differences(P<0.05).Conclusions Both berberine and curcumin can inhibit the activity of M1-type macrophages and reduce inflammatory response.The action of berberine combined with curcumin is more advantageous than that of either drug alone,which may be the main mechanism of action through activation of STAT6.

Objective:To evaluate the effect of different reconstruction points of intrauterine applicator on the source dwell positions and plan dosimetry in intracavitary brachytherapy for cervical cancer.Methods:Clinical data of 43 patients with cervical cancer who had completed radical radiotherapy in Liuzhou Workers' Hospital from May 2020 to October 2022 were retrospectively analyzed. Among 43 patients, aged 32-79 years, 40 cases were diagnosed with squamous carcinoma and 3 cases of adenocarcinoma. All patients received external irradiation for 50.4 Gy / 28 fractions and CT-guided intracavitary brachytherapy (45° intrauterine applicator) was 36 Gy / 6 fractions. Brachytherapy was performed by using Fletcher applicator, the curvature of intrauterine applicator were 15°, 30°and45°. Two sets of brachytherapy plans were simulated for each patient. One set of plans extracted the simulated CT positioning images and the original plan of the patient's brachytherapy. The reconstruction point of the curved part of the 45° intrauterine applicator was adjusted to slice-by-slice reconstruction. The plan was optimized to meet clinical requirements according to the prescription, which was called the slice-by-slice group. In the other set of plans, slice-by-slice group was used as a template. The reconstruction points of the curved section of the 45° intrauterine applicator were adjusted to 1, 3, 5, and 7, without modifying the applicator weights and other parameters, which was called the average group 1, 3, 5 and 7. The deviation analysis of 15°, 30° and 45° intrauterine applicator with different number of reconstruction points was carried out, the reconstruction deviation of 45°, 30° and 15° intrauterine applicator at different reconstruction points was compared. Paired-sample t-test or Wilcoxon signed rank test were used to compare the differences in high-risk clinical target volume (HR-CTV) D 50%, D 90%, D 100%, V 100%, V 150%, V 200% and conformity index (CI) as well as D 2 cm3, D 1 cm3 and D 0.1 cm3 in bladder, rectum, and small intestine between two groups of 45° intrauterine applicator. Results:The reconstruction deviation in the average group was mainly from the vertical direction of the 45° intrauterine applicator. The mean reconstruction deviations of 45° (1, 3, 5, 7 reconstruction points), 30° (1, 3, 5 reconstruction points) and 15° (1, 2 reconstruction points) were 1.30 mm, 0.32 mm, 0.14 mm and 0.08 mm; 0.57 mm, 0.14 mm and 0.06 mm; 0.14 mm and 0.06 mm, respectively. There was no significant difference in the parameters of high-risk clinical target volume (HR-CTV) in the slice-by-slice group compared with the average group 5 and 7 (all P>0.005), and no significant difference was found between the average group 5 and 7 (all P>0.005). There were no statistically significant differences in bladder and rectum doses between the slice-by-slice group and the average groups or within the average groups (all P>0.005). The parameters of small intestine in the slice-by-slice group were higher than those of the average group 1, the difference was statistically significant ( P=0.002,<0.001,<0.001). The dose of small intestine in the slice-by-slice group was not statistically significant compared with those in the average group 5 and 7 (both P>0.005). The dose of small intestine in the average group 5 was not statistically significant compared with that in the average group 7 ( P>0.005). The small intestine dose deviations of D 0.1 cm3, D 1 cm3 and D 2 cm3 in the average groups at 1 reconstruction point were 2.41%±1.70%, 1.95%±1.27% and 1.71%±1.10%, respectively. Conclusion:The number of reconstruction points is recommended to be no less than 1, 3 and 5 of the curved part of the 15°, 30°and 45° Fletcher intrauterine applicator, respectively, during intracavitary brachytherapy for cervical cancer.

Objective Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is the leading cause of hospitalization and death in patients with chronic obstructive pulmonary disease (COPD). Exploring the prognostic factors of AECOPD patients will assist in optimizing treatment strategies and standardizing disease management. Methods This study retrospectively collected the clinical data of 664 patients with AECOPD admitted to the Respiratory Department of Dongzhimen Hospital of Beijing University of Chinese Medicine from January 2013 to September 2019. The 3-year survival rate and treatment of the patients were investigated. According to whether the patients died,they were divided into a non-survivors group and a survivors group,and clinical data such as basic information,comorbidities,and auxiliary examination results were compared between the two groups. Incorporating clinical experience of researchers and previous research evidence,a secondary screening of variables was conducted to ultimately determine the covariates to be included in the multifactorial Cox proportional hazards regression model,and the factors affecting the 3-year survival rate of the patients were analyzed. Results A total of 664 cases were included in this study,including 362 males and 302 females,with an average age of (77.25±6.89) years old. The 3-year all-cause mortality rate of older hospitalized patients with AECOPD was 20.48％(136 patients). Older age (HR:1.071,95％CI:1.040-1.102,P<0.001);smoking history (HR:1.788,95％CI:1.173-2.723,P=0.007);Charlson comorbidity index (HR:1.209,95％CI:1.029-1.421,P=0.022);lower arterial partial pressure of oxygen (HR:1.014,95％CI:1.006-1.022,P<0.001);higher brain natriuretic peptide(HR:1.001,95％CI:1.000-1.001,P=0.025);cor pulmonale(HR:1.896,95％CI:1.235-2.908,P=0.004);respiratory failure (HR:2.437,95％CI:1.378-4.311,P=0.003);TCM syndrome differentiation elements,including kidney (HR:1.639,95％CI:1.055-2.546,P=0.028) and fluid retention (HR:2.512,95％CI:1.653-3.816,P<0.001),were independent risk factors for 3-year all-cause death of older hospitalized patients with AECOPD. Long-term regular use of bronchiectasis (HR:0.474,95％CI:0.324-0.695,P<0.001) was an independent protective factor for 3-year all-cause death. Conclusion The 3-year survival rate of elderly hospitalized patients with AECOPD is relatively low,with the TCM syndrome elements manifested as lung-kidney qi deficiency,yang deficiency with water retention,and blood stasis obstruction. Patients with moderate to severe impairment of lung function due to COPD have an increased risk of death within 3 years. Therefore,for such patients,nourishing lung-kidney qi,resolving phlegm and water retention,activating blood circulation to remove blood stasis and dredging collaterals,combined with regular use of bronchodilators,may help improve their 3-year survival rate.

Objective To explore the correlation between serum fibroblast growth factor-23(FGF23),Klotho protein levels and cardiac valve calcification(CVC)in patients with maintenance hemodialysis(MHD).Methods A total of 169 MHD patients in the Blood Purification Center of Jinshan Hospital,Fudan University from January 2022 to January 2023 were selected.The patients'CVC status was examined by color Doppler echocardiography.Results There were 111 CVC cases,accounting for 65.68%.Compared with the non-CVC group,the CVC group had significantly higher levels of FGF23,β2-microglobulin,brain natriuretic peptide(BNP),age,and the proportion of male,while significantly lower levels of Klotho,predialysis creatinine,hemoglobin,plasma albumin and iPTH(P＜0.05).Pearson/Spearman correlation coefficient analysis showed that FGF23,age,β2-microglobulin and BNP were significantly positively correlated with CVC(r=0.20,0.41,0.15,0.28,0.12),while Klotho,predialysis creatinine,hemoglobin,plasma albumin and iPTH were significantly negatively correlated with CVC(r=﹣0.16,﹣0.17,﹣0.16,﹣0.17,﹣0.16).Unconditioned binary logistic regression analysis showed that FGF23,Klotho,age and β2-microglobulin were independent risk factors for CVC in MHD patients.Conclusions MHD patients are prone to CVC.Serum FGF23 protein level is significantly positively correlated with CVC,while Klotho protein level is significantly negatively correlated with CVC.FGF23,Klotho,age and β2-microglobulin are independent risk factors for CVC in MHD patients.

Acral melanoma(AM)is the most common histologic subtype of melanoma in dark-skinned patients and is associated with a worse prognosis and a high mortality rate,largely due to the inconspicuous nature of early-stage lesions,which can lead to late diagnosis.Because of the overlapping clinical and histopathological features of AM with other forms of cutaneous melanomas,early detection of AM requires a multidisciplinary approach that integrates various diagnostic modalities,including clinical examination,dermoscopy,histopathology,molecular testing,radiological imaging,and blood tests.While surgery is the preferred method of treatment for AM,other therapeutic options may be employed based on the stage and underlying etiology of the disease.Immune checkpoint inhibitors,molecular targeted therapy,radiotherapy,chemotherapy,and oncolytic virotherapy represent promising advanced treatment options for AM.In this review,we provide an overview of the latest advancements in diagnostic and therapeutic methods for AM,highlighting the importance of early detection and the prompt,individualized management of this challenging disease.

To investigate the γ pass rate limit of plan verification equipment for volumetric modulated arc therapy (VMAT) plan verification and its sensitivity on the opening and closing errors of multi-leaf collimator (MLC), 50 cases of nasopharyngeal carcinoma VMAT plan with clockwise and counterclockwise full arcs were randomly selected. Eight kinds of MLC opening and closing errors were introduced in 10 cases of them, and 80 plans with errors were generated. Firstly, the plan verification was conducted in the form of field-by-field measurement and true composite measurement. The γ analysis with the criteria of 3% dose difference, distance to agreement of 2 mm, 10% dose threshold, and absolute dose global normalized conditions were performed for these fields. Then gradient analysis was used to investigate the sensitivity of field-by-field measurement and true composite measurement on MLC opening and closing errors, and the receiver operating characteristic curve (ROC) was used to investigate the optimal threshold of γ pass rate for identifying errors. Tolerance limits and action limits for γ pass rates were calculated using statistical process control (SPC) method for another 40 cases. The error identification ability using the tolerance limit calculated by SPC method and the universal tolerance limit (95%) were compared with using the optimal threshold of ROC. The results show that for the true composite measurement, the clockwise arc and the counterclockwise arc, the descent gradients of the γ passing rate with per millimeter MLC opening error are 10.61%, 7.62% and 6.66%, respectively, and the descent gradients with per millimeter MLC closing error are 9.75%, 7.36% and 6.37%, respectively. The optimal thresholds obtained by the ROC method are 99.35%, 97.95% and 98.25%, respectively, and the tolerance limits obtained by the SPC method are 98.98%, 97.74% and 98.62%, respectively. The tolerance limit calculated by SPC method is close to the optimal threshold of ROC, both of which could identify all errors of ±2 mm, while the universal tolerance limit can only partially identify them, indicating that the universal tolerance limit is not sensitive on some large errors. Therefore, considering the factors such as ease of use and accuracy, it is suggested to use the true composite measurement in clinical practice, and to formulate tolerance limits and action limits suitable for the actual process of the institution based on the SPC method. In conclusion, it is expected that the results of this study can provide some references for institutions to optimize the radiotherapy plan verification process, set appropriate pass rate limit, and promote the standardization of plan verification.
