Objective To observe the clinical efficacy of Fangxiang Wentong Powder(composed of Salviae Miltiorrhizae Radix et Rhizoma,Chuanxiong Rhizoma,Alpiniae Officinarum Rhizoma,Piper Longum,and Corydalis Rhizoma)acupoint application combined with Kuanxiong Aerosol in treating female patients with coronary slow flow(CSF)associated angina.Methods After sample size estimation,119 female inpatients diagnosed as CSF associated angina and differentiated as chest-qi obstruction with yang deficiency and cold accumulation syndrome of traditional Chinese medicine(TCM)were collected from the cardiovascular departments of the Third People's Hospital of Fujian University of Traditional Chinese Medicine,the Second Affiliated Hospital of Guangzhou University of Chinese Medicine(Guangdong Provincial Hospital of Chinese Medicine),Zhanjiang First Traditional Chinese Medicine Hospital,and Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from November 2023 to March 2024.Using a table of random numbers,the patients were divided into a treatment group(84 cases)and a control group(35 cases)in a ratio of 5∶2.The control group was treated with Isosorbide Monomitrate Sustained-Release Capsules,while the treatment group was treated with application of Fangxiang Wentong Powder on acupoints of Danzhong(CV17),Gaohuang(BL43),and Xinshu(BL15),together with sublingual administration of Kuanxiong Aerosol.The treatment course for both groups covered 7 days.Before and after treatment,the changes in the simplified Seattle Angina Questionnaire(SAQ-7)scores,Chinese Quality of Life Questionnaire for Cardiovascular Patients(CQQC)scores,6-minute walking distance(6MWD),serum C-reactive protein(CRP)level,and white blood cell-to-mean platelet volume ratio(WMR)were observed.The TCM symptom efficacy was compared between the two groups,and adverse reactions were monitored.Results(1)There were 8 patients withdrew in the treatment group for failing in completing the questionnaires,and 2 patients withdrew in the control group for suffering headaches after taking nitrates.Eventually,109 patients completed the trial,including 76 in the treatment group and 33 in the control group.(2)After 7 days of treatment,the total effective rate for TCM symptom efficacy in the treatment group was 86.84%(66/76),and that in the control group was 72.73%(24/33).The intergroup comparison(tested by the chi-square test)showed that the TCM symptom efficacy in the treatment group was significantly superior to that in the control group.(3)After treatment,both groups showed improvements in the scores of activity limitation and angina frequency items of SAQ-7,and the treatment group also showed improvements in the scores of subjective satisfaction item of SAQ-7(P＜0.05).The treatment group's improvements in the scores of activity limitation,angina frequency,and subjective satisfaction items of SAQ-7 were significantly superior to those of the control group(P＜0.05).(4)After treatment,the CQQC scores in the treatment group was significantly improved(P＜0.05),while no significant improvement was observed in the control group(P＞0.05).The improvement of CQQC scores in the treatment group was significantly superior to that in the control group(P＜0.05).(5)After treatment,both groups showed improvements in 6MWD(P＜0.05),and the improvement in the treatment group was significantly superior to that in the control group(P＜0.05).(6)After treatment,the serum levels of inflammatory indicators of CRP and WMR in the treatment group were significantly improved(P＜0.05),while no significant improvements were presented in the control group(P＞0.05).The improvements in serum CRP level and WMR value in the treatment group were significantly superior to those in the control group(P＜0.05).(7)No adverse reactions were found in the treatment group,indicating high safety.Conclusion Fangxiang Wentong Powder acupoint application combined with Kuanxiong Aerosol is more effective than Isosorbide Monomitrate Sustained-Release Capsules,improving exercise tolerance,decreasing inflammatory factor levels,and improving the quality of life to some extent during the treatment of female patients with CSF.

Background: In suckling piglets, transmissible gastroenteritis virus (TGEV) causes lethal diarrhea accompanied by high infection and mortality rates, leading to considerable economic losses. This study explored methods of preventing or inhibiting their production.Bovine antimicrobial peptide-13 (APB-13) has antibacterial, antiviral, and immune functions. Objectives: This study analyzed the efficacy of APB-13 against TGEV through in vivo and in vitro experiments. Methods: The effects of APB-13 toxicity and virus inhibition rate on swine testicular (ST) cells were detected using 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT). The impact of APB-13 on virus replication was examined through the 50% tissue culture infective dose (TCID50 ). The mRNA and protein levels were investigated by real-time quantitative polymerase chain reaction and western blot (WB). Tissue sections were used to detect intestinal morphological development. Results: The safe and effective concentration range of APB-13 on ST cells ranged from 0 to 62.5 µg/mL, and the highest viral inhibitory rate of APB-13 was 74.1%. The log10 TCID50 of 62.5 µg/mL APB-13 was 3.63 lower than that of the virus control. The mRNA and protein expression at 62.5 µg/mL APB-13 was significantly lower than that of the virus control at 24 hpi. Piglets in the APB-13 group showed significantly lower viral shedding than that in the virus control group, and the pathological tissue sections of the jejunum morphology revealed significant differences between the groups. Conclusions APB-13 exhibited good antiviral effects on TGEV invivo and in vitro.

Objective:To explore the diagnosis and treatment strategies of primary ciliary dyskinesia (PCD).Methods:A 37-year-old male recipient who had repeated cough and sputum from childhood, with shortness of breath after activity and progressive development, the number of hospitalizations per year was ≥6 times, the MRC score was 2~3 diagnosed with primary ciliary dyskinesia through medical examination and multidisciplinary consultation, and received allogeneic double lung transplantation after medical treatment failure. Search related domestic and foreign literatures to explore and analyze the etiology, pathogenesis, clinical manifestations and imaging features, diagnosis and treatment of PCD.Results:PCD is an autosomal hereditary disease. Due to abnormal skeletal structure and/or functional development, clinical manifestations are mostly chronic sinusitis, bronchiectasis, otitis media and infertility. Chest imaging showed situs inversus totalis, right heart and diffuse cystic bronchiectasis infection with bronchial wall thickening, diagnosis depends on clinical manifestations, saccharin test, nasal nitric oxide test, high-speed video microscopy analysis, transmission electron microscopy, genetic testing and immunofluorescence.Conclusions:Lung transplantation is the only effective treatment for end-stage PCD. It not only saves patients' lives, but also significantly improves their quality of life.
