Objective To explore the medication rules in the patented Chinese medicine(CM)compound formulas for the prevention and treatment of respiratory infectious diseases,and to provide reference for the prevention and treatment of respiratory infectious diseases.Methods CM compound formulas for the prevention and treatment of respiratory infectious diseases were collected from the national patent database.After data screening and standardization,R language was used for data mining.Results A total of 429 patented CM compound formulas were included,involving 846 Chinese medicinals.There were 26 kinds of high-frequency Chinese medicinals,and the top 10 frequently-used drugs were Glycyrrhizae Radix et Rhizoma,Lonicerae Japonicae Flos,Scutellariae Radix,Forsythiae Fructus,Platycodonis Radix,Stemonae Radix,Armeniacae Semen Amarum,Astragali Radix,Bupleuri Radix,and Menthae Haplocalycis Herba.Most of the high-frequency Chinese medicinals were heat-clearing and toxin-removing drugs and qi-replenishing drugs.The medicinal properties of the patented CM compound formulas were usually cold,the medicinal flavors were usually bitter,sweet and pungent,and mostly had the meridian tropism of lung meridian.The association rule analysis yieled 19 core association rules and multiple drug combinations.Three drug clusters were obtained after cluster analysis.Conclusion For the prevention and treatment of respiratory infectious diseases,patented CM compound formulas are commonly formulated following the principles of compatibility of cold and warm drugs,compatibility of drugs for dispersing and descending,usually have the actions of dispersing pathogens in the lung,clearing heat and removing toxins,and also have the actions of replenishing qi and harmonizing the middle energizer,and nourishing yin and moistening dryness.The formulas have the efficiency of eliminating pathogens while not hurting the healthy qi,and strengthening the healthy qi while not maintaining pathogens.

The multiple systemic symptoms appearing during the convalescence of novel coronavirus infection(COVID-19)are called long-term symptoms after COVID-19,also named as long COVID.Traditional Chinese medicine(TCM)has unique advantages in the treatment of long COVID.In the view of Professor ZHANG Zhong-De,the novel coronavirus infection belongs to the category of damp-toxin pestilence in TCM.During the convalescence of novel coronavirus infection,the damp-toxin pathogen causes the dysfunction of qi,blood,yin and yang of zang-fu organs,and then results in the consumption of yang qi or the depletion of fluid and blood.Damp-turbidity obstructing qi movement and entering collaterals and then developing into blood stasis is the key pathogenesis of long COVID.Therefore,the therapeutic principle of harmonizing yin,yang,qi and blood of the five zang-organs is proposed,and the methods for transporting and transforming damp-toxin and phlegm-turbidity,regulating qi,activating blood and removing stasis should be adopted.According to the exuberance or decline of qi,blood and body fluid,and yin and yang of the five zang-organs,the Fuzheng Series Formulas(series formulas for supporting healthy qi)were recommended for the specific syndrome types:Fuzheng Shengbai Formula can be used for the syndrome of deficiency of original qi;Fuzheng Yifei Formula can be used for lung-spleen-kidney deficiency syndrome;Fuzheng Anshen Formula can be used for the syndrome of liver qi stagnation and heart-spleen deficiency.During the treatment,Professor ZHANG Zhong-De makes the modification of drugs indicated for the retention sites of damp-toxin and turbid qi,and addresses the importance of spleen and stomach in the whole treatment process by protecting spleen and stomach,so as to promote the rehabilitation of patients after novel coronavirus infection and improve their quality of life.

Objective To explore the risk factors for bile leakage after laparoscopic common bile duct exploration(LCBDE)with primary closure.Methods The clinical data of 560 patients with choledocholithiasis who underwent LCBDE with primary closure in Tianjin Hospital of Integrated Traditional Chinese and Western Medicine from September 2021 to September 2023 were retrospectively analyzed,and the patients were divided into the bile leak group and the non-bile leak group according to the occurrence of postoperative bile leakage.The risk factors affecting the occurrence of postoperative bile leakage were analyzed by multivariate analysis.Results A total of 64 cases(11.4% )experienced varying degrees of bile leakage,including 55 cases of grade A bile leakage,7 cases of grade B,and 2 cases of grade C.The thin common bile duct(OR=0.07,P<0.001),history of hypertension(OR=4.56,P<0.001),and high BMI(OR=1.17,P=0.002)were the risk factors for postoperative bile leakage in patients with choledocholithiasis.Conclusion Patients with thin common bile duct,hypertension and obesity are more likely to occur postoperative bile leakage.Patients with choledocholithiasis who have the above high-risk factors should be cautious in choosing LCBDE with primary closure.

"Solid-liquid excipients" co-production is one of the typical processing methods of excipients used from ancient times to the present day, and is widely applied in various processing schools and regional specialty varieties. This method significantly reduces the toxicity of traditional Chinese medicine(TCM), moderates medicinal properties, and enhances clinical efficacy. However, modern scientific research has given it limited attention, and many co-production methods of "solid-liquid excipients" have not been applied in production and practice. This paper reviewed the historical development of "solid-liquid excipients" co-production, outlined modern processing standards and methods in different processing schools, and further elaborated on the purposes and effects of this co-production method. This study is expected to provide references and evidence for further in-depth research, inheritance, innovation, and practical application.

Obstructive sleep apnea hypopnea syndrome(OSAHS)is the common sleep-related breathing disorders,which is prone to develop into multi-organ and multi-system damages.OSAHS can be categorized as"snoring syndrome"in traditional Chinese medicine(TCM).Professor ZHANG Zhong-De,a national famous Chinese medical practitioner,advocates to treat OSAHS with the method of uniform regulation of five zang organs,and emphasizes the importance of pathogenesis of imbalance of the five zang-organs.In his view,failure of lung qi in dispersing and descending is the basic pathogenesis of OSAHS,spleen and stomach failing in transporting and transforming as well as internal retention of phlegm-damp is the key pathogenic factors of OSAHS,and heart-kidney yang deficiency and liver blood insufficiency contribute to the fundamental pathogenesis of OSAHS.In the course of OSAHS,the yin and yang,qi and blood of the five zang organs become imbalanced,which leads to the progression of the disease.The treatment based on syndrome differentiation for OSAHS aims at restoring the state of balance.Following the principle of uniform regulation,methods of invigorating spleen,ventilating lung,warming heart and kidney,and nourishing liver blood are used for the uniform regulation of five zang organs,so as to keep the dynamic balance among the organs and to cure the disease.

Objective: To explore the current situation of fetal heart defects in Yunnan Province and surrounding high altitude areas and the social factors affecting pregnancy outcome. Methods: This is a retrospective study. Pregnant woman who underwent fetal echocardiography and diagnosed as fetal cardiac defects in Yunnan Fuwai Cardiovascular Hospital from June 2017 to January 2021 were included. According to the clinical prognostic risk scoring system and grading criteria of fetal cardiac birth defects, the cases were divided into grade Ⅰ to Ⅳ. The disease distribution and proportion of each prognostic grade, pregnancy outcomes were analyzed and compared. The cases were divided into continued pregnancy group and terminated pregnancy group according to pregnancy outcome. The social factors that may affect the selection of pregnancy outcomes were analyzed by multivariate logistic regression analysis. Results: A total of 4 929 fetal echocardiography examination data were collected, and 4 464 cases (90.57%) were from Yunnan Province and surrounding high altitude areas. 2 166 cases of heart defects were finally analyzed, including 998 cases of congenital heart disease (CHD), 93 cases of cardiac tumors, cardiomyopathy and arrhythmia, 1 075 cases of foramen ovale, ductus arteriosus abnormalities and normal variations. The pregnant women were (29.2±5.0) years old with (25.6±3.8) gestational weeks. The number of cases with prognostic grade from Ⅰ to Ⅳ was 1 037 (47.88%), 620 (28.62%), 314 (14.50%), and 44 (2.03%), respectively. And 151 cases (6.97%) were not classified. The cases of normal variation and thin aortic arch development accounted for 42.66% (924/2 166), 5.22% (113/2 166), respectively. The top 3 diseases of grade Ⅱ were ventricular septal defect, coarctation of aorta and mild-moderate pulmonary stenosis, respectively, and their distribution was 11.63% (252/2 166), 3.92% (85/2 166) and 2.35% (51/2 166) respectively in all cases of heart defects, and 25.25% (252/998), 8.52% (85/998) and 5.11% (51/998) respectively in cases of CHD. Among the cases rated as grade Ⅲ and Ⅳ, most of them were complicated congenital heart disease, and the disease types are scattered. The more common cases in grade Ⅲ were complete transposition of great arteries (accounting for 2.40% (52/2 166) of all cases with heart defects, 5.21% (52/998) of all cases with CHD) and pulmonary artery occlusion (type Ⅰ to Ⅲ) with ventricular septal defect (accounting for 2.17% (47/2 166) of all cases with heart defects, and 4.71% (47/998) of all cases with CHD). In grade Ⅳ, single ventricle (0.74% (16/2 166) of all cases with heart defects, 1.60% (16/998) of all cases with CHD) and left ventricular dysplasia syndrome (0.65% (14/2 166) of all cases with heart defects, 1.40% (14/998) of all cases with CHD) are more common. A total of 1 084 cases were successfully followed up, and 675 cases were born, 392 cases were terminated, spontaneous abortion occurred in 17 cases. The proportion of terminated pregnancy cases was significantly increased from grade Ⅰ to Ⅳ, accounting for 5.24% (21/401), 27.78% (70/252), 89.54% (214/239) and 95.56% (43/45), respectively. Among the terminated pregnancy cases, those with grade Ⅲ accounted for the highest proportion (54.59% (214/392)). The distribution of terminated pregnancy cases was mainly complex congenital malformations or diseases with very poor prognosis (pregnancy outcome grade Ⅲ and Ⅳ), and proportion of terminated pregnancy with pregnancy outcome grade Ⅰ and Ⅱ cases (normal variation or good prognosis) accounted for 5.36% (21/392) and 17.86% (70/392), respectively. The results of multivariate logistic regression analysis showed that pregnant women with low education (high school and below: OR=2.73, 95%CI 1.26-5.93, P<0.001; illiteracy: OR=3.27, 95%CI 1.29-7.10, P<0.001) and low family income (Annual income<100 000 yuan: OR=2.47, 95%CI 1.69-5.12, P<0.001) were more likely to choose termination of pregnancy in case of fetal heart defect. Conclusion: In Yunnan province and the surrounding high altitude areas, the disease distribution of fetal heart defect is mainly simple or low-risk disease, but the complex malformation, especially the disease with poor pregnancy outcome, accounts for a relative high proportion. Pregnancy termination also occurs in some cases with good pregnancy outcome. The education level and family income of pregnant women may affect their choice of pregnancy outcome in case of fetal heart defect.

Circadian rhythm is an internal regulatory mechanism formed in organisms in response to the circadian periodicity in the environment, which modulates the pathophysiological events, occurrence and development of diseases, and the response to treatment in mammals. It significantly influences the susceptibility, injury, and recovery of ischemic stroke, and the response to therapy. Accumulating evidence indicates that circadian rhythms not only regulate the important physiological factors of ischemic stroke events, such as blood pressure and coagulation-fibrinolysis system, but also participate in the immuno-inflammatory reaction mediated by glial cells and peripheral immune cells after ischemic injury and the regulation of neurovascular unit(NVU). This article aims to link molecular, cellular, and physiological pathways in circadian biology to the clinical consequences of ischemic stroke and to illustrate the impact of circadian rhythms on ischemic stroke pathogenesis, the regulation of NVU, and the immuno-inflammatory responses. The regulation of circadian rhythm by traditional Chinese medicine is reviewed, and the research progress of traditional Chinese medicine intervention in circadian rhythm is summarized to provide a reasonable and valuable reference for the follow-up traditional Chinese medicine research and molecular mechanism research of circadian rhythm.
