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 investigate the role of homologous genes absent from the wings of drosophila melanogaster(Notch)signaling pathway in the imbalance of helper T cells 1(Th1)and helper T cells 2(Th2)and the intervention mechanism of Qizhi Zhoufei Granule in chronic obstructive pulmonary disease(COPD).Methods Ten of seventy Wistar rats were selected as the blank control group,and the other rats were established by cigarette smoking combined(CS)with tracheal infusion of lipopolysaccharide(LPS).The COPD model was established by randomly selecting 3 rats in the control group and the model group to verify the success of the model.At the end of modeling,gavage administration was performed.The rats in the model group were randomly divided into model control group,positive control group(67.5 μg·kg-1)and Qizhi Zhoufei Granule high,medium and low treatment group(3.24,1.62,0.81 g·kg-1).Each group was treated with normal saline,dexamethasone acetate suspension and Qizhi Zhoufei Granule suspension at high,medium and low doses.The rats in the blank control group were given the same volume of normal saline as the model control group.After modeling with 28 days and treatment with 28 days,peak inspiratory flow(PIF)and peak expiratory flow(PEF)were detected by the animal lung function test system.Rats were killed to extract lungs,spleen,serum and bronchoalveolar lavage fluid(BALF),hematoxylin-eosin(HE)staining was used to evaluate the pathological changes of lung tissues.The level of tumor necrosis factor-α(TNF-α)in serum and BALF was determined by enzyme-linked immunosorbent assay(ELISA).Flow cytometry was used to detect Th1/Th2 cells in spleen.Immunohistochemistry(IHC)and western blot were used to detect Notch1,Hes1 and Hey1 protein levels in lung tissues.Real-time fluorescence quantitative polymerase chain reaction(Real-Time PCR)was used to detect Notch1,Hes1 and Hey1 gene expression levels in lung tissues.Result Compared with the blank control group,the lung function of the model control group was significantly decreased(P<0.05),inflammatory cell infiltration and bronchial structure destruction occurred in the lung tissue,TNF-α content in serum and BALF increased significantly(P<0.05),the percentage of spleen Th1 cells was significantly decreased(P<0.05),and the percentage of Th2 cells was significantly increased(P<0.05),the protein and mRNA expressions of Notch1,Hes1 and Hey1 in lung tissues were significantly increased(P<0.05),the differences were statistically significant;Compared with the model control group,the lung function of rats in each administration group was significantly increased(P<0.05),the pathological injury of lung tissue was alleviated,TNF-α content in serum and BALF decreased significantly(P<0.05),the percentage of spleen Th1 cells was significantly increased(P<0.05),the percentage of Th2 cells was significantly decreased(P<0.05),the lung tissue of Notch1,Hes1,Hey1 protein and mRNA expression were significantly decreased(P<0.05),the differences were statistically significant.Conclusion Qizhi Zhoufei Granule regulate Th1/Th2 balance by inhibiting Notch signaling pathway,thereby improving pulmonary function and pathological injury,and affecting immune function in COPD rats.

[Purpose]To investigate the trends of incidence and age at onset of uterine corpus can-cer in Jiangsu cancer registration areas from 2009 to 2019.[Methods]The continuous monitoring data of uterine corpus cancer from 2009 to 2019 were collected from 16 cancer registries in Jiang-su Province.The crude incidence rate,the age-standardized incidence rate by Chinese standard population(ASIRC),crude and adjusted mean age,and standardized age-specific incidence composition were calculated.The average annual percentage change(AAPC)were analyzed by the Joinpoint regression model.The linear regression model was used to analyze the relationship be-tween mean age at onset and year.The standardized age-specific incidence composition in 2009 and 2019 were compared.[Results]The ASIRC of uterine corpus cancer in all registration areas and in rural areas of Jiangsu Province showed upward trends with AAPC of 1.78％and 2.38％,re-spectively(P＜0.05),but not showed in the urban areas(AAPC=1.30％,P＞0.05).The crude mean age at onset increased from 56.48 years old in 2009 to 58.26 years old in 2019 with an average annual growth of 0.173 years old(P=0.001).After the population structure standardized,the trends disappeared in all registration areas.[Conclusion]From 2009 to 2019,the standardized incidence rates of uterine corpus cancer were on rise in Jiangsu cancer registration areas,especially in the age group of 50 to 59 years old.

Objective:To summarize the features of stenosis or premature closure of fetal ductus arteriosus and to investigate the perinatal management strategies.Methods:Three cases diagnosed with stenosis or premature closure of fetal ductus arteriosus in Peking University First Hospital between January 2022 and June 2022 were retrospectively enrolled. Clinical features and perinatal management strategies were summarized.Results:Fetal cardiac abnormalities (right heart enlargement and tricuspid regurgitation) were detected in the three cases by routine prenatal ultrasound at the gestational weeks of 24, 30 and 23, respectively. Fetal echocardiography confirmed the diagnosis of stenosis or premature closure of fetal ductus arteriosus and no other structural anomalies were detected. All three pregnant women denied taking non-steroidal anti-inflammatory drugs. Case 1 and case 2 underwent emergency cesarean section due to suspected fetal cardiac dysfunction with a cardiovascular profile score of 6 and 5. The two neonates were transferred to the neonatal intensive care unit and discharged with good prognosis (normal cardiac function) on the 56th and 42nd day after birth. During a close monitoring, the stenosis of fetal ductus arteriosus improved in case 3 and a full-term neonate was delivered at 38 weeks by elective cesarean section because of a history of cesarean section.Conclusions:In the second and third trimesters of pregnancy, attention should be drawn to the fetal ductus arteriosus during ultrasound imaging, especially when right heart enlargement and tricuspid regurgitation were detected. For fetuses with suspected ductus arteriosus stenosis, a close monitor of the ductus arteriosus and the ultrasound findings indicating cardiac dysfunction is needed and the cardiovascular profile score should also be involved. Fetuses with premature closure of the ductus arteriosus should be delivered promptly and the postnatal cardiac outcomes are good.

Objective: To explore the role of mobile phone addiction and anxiety symptoms in the relationship between childhood psychological abuse and depressive symptoms among college students, in order to provide a basis for mental health promotion. Methods: From February to May 2023, a stratified random sampling method was used to select 1 799 freshmen to juniors from a university in Wuhu City, Anhui Province. The questionnaire survey was conducted using the 2-item Patient Health Questionnaire (PHQ-2), Child Psychological Maltreatment Scale (CPMS), Mobile Phone Addiction Tendency Scale (MPATS), 2-item General Anxiety Disorder (GAD-2). Correlations among each variable were analyzed, and the chain mediating effect of mobile phone addiction and anxiety symptoms was explored. Results: The detection rate of depressive symptoms among college students was 9.7%, and the positive detection rate of childhood psychological abuse was 28.6%. Depressive symptoms were positively correlated with childhood psychological abuse, mobile phone addiction and anxiety symptoms ( r =0.28, 0.32, 0.27, P <0.01). Childhood psychological abuse was positively correlated with mobile phone addiction and anxiety symptoms ( r =0.29, 0.71, P <0.01). Mobile phone addiction and anxiety symptoms were positively correlated ( r =0.30, P <0.01). Childhood psychological abuse could effectively predict depressiove symptoms, mobile phone addiction and anxiety symptoms ( β =0.08, 0.06, 0.66, P <0.01). Mobile phone addiction and anxiety symptoms had a chain mediating effect between childhood psychological abuse and depression symptoms, with a total indirect mediating effect (effect=25.27%, P <0.05), accounting for 72.44% of the total effect. Conclusions Mobile phone addiction and anxiety symptoms play a chain mediating role between childhood psychological abuse and depressive symptoms. Focusing on childhood psychological abuse, mobile phone addiction and anxiety among college students are beneficial for depression symptoms prevention.

Chronic obstructive pulmonary disease （COPD） is characterized by long treatment course and poor prognosis. The pathogenesis has not been fully elucidated but is mostly related to the non-specific inflammation of the airway and surrounding tissues. T helper 1 （Th1） and T helper 2 （Th2） are generated by CD4⁺ T cell differentiation， and are in a dynamic equilibrium when the body is in normal state. The balance between pro-inflammatory cytokines and anti-inflammatory cytokines regulated by Th1/Th2 is vital for maintaining the immune homeostasis in respiratory tract. Chronic inflammatory state changes the level of inflammatory cells in the body， and there is immune disorder in T lymphocytes in the onset stage of COPD. Th1 cells are predominantly expressed in the stable stage of COPD， while Th2 cells are predominantly expressed in the acute exacerbations of COPD （AECOPD）. Th1/Th2 immune imbalance aggravates the inflammatory reaction， and thus restoring the immune balance between them and inhibiting the inflammatory reaction are critical for the treatment of COPD. At present， there has been no satisfactory treatment plan for COPD. Chinese medicine has a long history of preventing and treating COPD， with remarkable curative effect and few adverse reactions. A large number of animal experiments and clinical studies on Chinese medicine intervention of Th1/Th2 immune balance in COPD have indicated that Th1/Th2 immune balance is an important potential target for treating COPD by Chinese medicine， which can correct chronic inflammatory state by regulating the immune disorder of the body. It has also been found that Th1/Th2 balance plays an important immunoregulatory role in inflammatory response， but little is known about its specific mechanism in the pathogenesis of COPD. On this basis， this paper summarized and analyzed the biological characteristics of Th1/Th2 and their mechanism in the pathogenesis of COPD， as well as the intervention effect of single Chinese medicine or its effective components and Chinese medicine compound on Th1/Th2 immune balance in COPD. It further explored the pathogenesis of COPD and the potential therapeutic targets of Chinese medicine in interfering with Th1/Th2 immune balance in COPD， providing reference for further study on prevention and treatment of COPD with Chinese medicine.

Objective To explore the classification and changes of macrophage subsets in liver transplant rejection.Methods Rat liver transplantation model were established and divided into immune tolerance group(B-B),where the liver of BN rat donors was transplanted to BN rat recipients,and immune rejection group(L-B),in which the liver of Lewis rat donors was transplanted to BN rat recipients.Single-cell RNA sequencing and high-throughput RNA sequencing were used to distinguish the macrophage subsets of rat liver transplantation,and to find differential gene in rejection reactions.Immunohistochemistry was used to determine the changes and distribu-tion of protein expression and cell subsets.Results CD68 positive macrophages were higher in the rejection group than that in the tolerance group(P<0.05),and macrophages could be divided into 9 subsets.During the rejection reaction,the CXC chemokine ligand 9(CXCL9)in the 8th subsets of macrophages was significantly increased,while the gene for white blood cell differentiation antigen 74(CD74)in the 5th subsets was significantly increased(P<0.05).CD74 ranked first in the differential gene synthesis of macrophages during rejection,followed by CXCL9.Compared with the tolerance group,a large number of CD74 positive macrophages were observed in the hepatic portal area of the rejection group,and the infiltration of CD74 positive macrophages in the hepatic sinuses was also significantly increased(P<0.05),while a large number of CXCL9 positive macrophages were observed in the hepatic portal area and hepatic sinuses of the rejection group,especially in the portal area(P<0.05),and CD14 positive cells were significantly increased(P<0.05).Conclusions The CD74 positive macrophage subsets and CXCL9 positive macrophage subsets may be key subgroups in promoting liver transplant rejection,improving the mechanism of macrophage action in liver transplant rejection.

Purpose: This study was aimed to investigate long-term survivals and toxicities of early-stage nasopharyngeal carcinoma (NPC) in endemic area, evaluating the role of chemotherapy in stage II patients. Materials and Methods: Totally 187 patients with newly diagnosed NPC and restaged American Joint Committee on Cancer/ International Union Against Cancer 8th T1-2N0-1M0 were retrospectively recruited. All received intensity-modulated radiotherapy (IMRT)±chemotherapy (CT) from 2001 to 2010. Results: With 15.7-year median follow-up, 10-year locoregional recurrence-free survival, distant metastasis-free survival (DMFS), disease-specific survival (DSS), and overall survival (OS) were 93.3%, 93.5%, 92.9% and 88.2%, respectively. Multivariable analyses showed cervical lymph nodes positive and pre-treatment prognostic nutritional index ≥ 52.0 could independently predict DMFS (p=0.036 and p=0.011), DSS (p=0.014 and p=0.026), and OS (p=0.002 and p < 0.001); Charlson comorbidity index < 3 points could predict DSS (p=0.011); age > 45 years (p=0.002) and pre-treatment lactate dehydrogenase ≥ 240 U/L (p < 0.001) predicted OS. No grade 4 late toxicity happened; grade 3 late toxicities included subcutaneous fibrosis (4.3%), deafness or otitis (4.8%), skin dystrophy (2.1%), and xerostomia (1.1%). No differences on survivals were shown between IMRT+CT vs. IMRT alone in stage II patients, even in T2N1M0 (p > 0.05). Unsurprising, patients in IMRT+CT had more acute gastrointestinal reaction, myelosuppression, mucositis, late ear toxicity, and cranial nerve injury (all p < 0.05) than IMRT alone group. Conclusion Superior tumor control and satisfying long-term outcomes could be achieved with IMRT in early-stage NPC with mild late toxicities. As CT would bring more toxicities, it should be carefully performed to stage II patients.
