Effects on type 2 diabetes complicated with pulmonary tuberculosis:regiment of insulin,isoniazid,rifampicin,pyrazinamide and ethambutol versus the regiment plus Qi-boosting and Yin-nourishing decoction of Traditional Chinese Medicine

OBjECTIVE:To observe the clinical effect on type 2diabetes mellitus(T2DM) complicated with pulmonary tuberculosis(TB) of insulin,isoniazid,rifampicin,pyrazinamide and ethambutol(conventional medication) administered together with Qi-boosting and Yin-nourishing decoction derived from Traditional Chinese Medicine(TCM).METHODS:A total of 60 patients with T2 DM complicated with pulmonary TB were randomly and equally divided into positive control group and treatment group.The control group was treated with Western conventional regiment(WCR):insulin,isoniazid,rifampicin,pyrazinamide,and ethambutol,whereas the treatment group was given both WCR and Qi-boosting and V/n-nourishing decoction prepared from TCM.RESULTS:After the treatment,20(66.7%) and 11(36.7%) cases showed sputum bacteria negative conversion in the WCR plus TCM group and WCM group respectively(P < 0.05).A total of 25(83.3%)and 18(60%) cases showed improvement in lung lesion in the WCR plus TCM group and WCM group respectively(P < 0.05).Compared with WCR group,fasting plasma glucose and 2-hour postprandial blood glucose levels in the WCR plus TCM group significantly decreased(P < 0.05 and P < 0.01,respectively).CONCLUSION:Qi-boosting and Yin-nourishing decoction combined with the Western medication showed better curative effect in treating T2 DM complicated with pulmonary TB compared with the group using the conventional Western Medicine alone.

Efficacy of the combination of modern medicine and traditional Chinese medicine in pulmonary fibrosis arising as a sequelae in convalescent COVID-19 patients: a randomized multicenter trial

Background:The coronavirus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)has led to a significant number of mortalities worldwide.COVID-19 poses a serious threat to human life.The clinical manifestations of COVID-19 are diverse and severe and 20%of infected patients are reported to be in a critical condition.A loss in lung function and pulmonary fibrosis are the main manifestations of patients with the severe form of the disease.The lung function is affected,even after recovery,thereby greatly affecting the psychology and well-being of patients,and significantly reducing their quality of life.

Acute effect of tetrandrine pulmonary targeting microspheres on hypoxic pulmonary hypertension in rats

Objective To assess the effect of tetrandrine (Tet) pulmonary targeting microspheres on hypoxic pulmonary hypertension and evaluate its selective action on pulmonary circulation.Methods Twenty rats were exposed to hypoxic conditions for 3 weeks. Ten rats were used as normoxic controls. We administered Tet pulmonary targeting microspheres to 10 hypoxic rats and Tet aqueous solution to 10 hypoxic rats and the 10 control rats. Mean pulmonary arterial pressure (mPAP) was measured by a right cardiac catheterization, and mean systemic blood pressure (mSBP) was measured by left femoral catheterization. Results Rats exposed to hypoxia developed pulmonary hypertension. The decrease in mPAP in rats treated with Tet pulmonary targeting microspheres was significantly greater than that in rats receiving Tet aqueous solution (P【0.05), and the effects were longer with Tet pulmonary targeting microspheres. Moreover, Tet pulmonary targeting microspheres, unlike Tet aqueous solution, did not decrease mSBP.Conclusion Tet pulmonary targeting microspheres were more effective than Tet aqueous solution in treating hypoxic pulmonary hypertension and acted selectively on the pulmonary circulation.

Management and outcomes of congenital chylothorax in the neonatal intensive care unit:A case series

Importance:Congenital chylothorax is a rare condition with pulmonary and multiorgan system effects,for which there are no standardized treatment recommendations.Collective review of known cases offers some conclusions and suggestions for treatment.Objective:The aim of this study was to present a case series of 5 patients who were treated in the neonatal intensive care unit with chylothorax.Methods:We describe 5 infants who were diagnosed prenatally with hydrops fetalis and postnatally had clinically significant congenital chylothorax.Results:Treatment guidelines specific to congenital forms of chylothorax have not yet been developed,although there are consistent trends across our cases.Four of the 5 infants in this study have survived to date.Chylothorax was treated with chest tube placement and chylous fluid drainage,scrupulous attention to fluid balance,mechanical ventilation,and nutritional management and,in 3 cases,with octreotide infusions.Some of the infants also required treatment for immunodeficiency and altered coagulation pathways.None of the infants underwent surgical thoracic duct ligation.Interpretation:Aided by the advantage of prenatal diagnosis,many cases of congenital chylothorax can be successfully treated by a combination of nutritional and medical management as well as careful attention to fluid and electrolyte balance and avoidance of infection,thereby avoiding the need for surgical ligation of the thoracic duct.

Synchronous Dynamic Research on Respiratory and Intestinal Microflora of Chronic Bronchitis Rat Model

Objective： To investigate the mechanism of the Chinese medicine theory that Fei（Lung） and Dachang（Large Intestine） are exteriorly and interiorly related via synchronous observation on the dynamic changes of the respiratory and intestinal microflora. Methods： Forty specific pathogen free Sprague-Dawley rats were selected and randomly divided into blank（10 rats） and chronic bronchitis model groups（30 rats）. The blank group rats were put into the smoke-free environment and the model group rats were put into the smoke environment in order to establish pulmonary disease（chronic bronchitis） model. Then the corresponding changes of the respiratory and intestinal microflora of the model on 20th, 50th and 70th days were synchronously observed. Results： The respiratory tract microflora showed an increase in the total aerobic and Staphylococcus aureus and reduced anaerobic amount significantly on 20th day in the respiratory tract microflora（P〈0.05 or 0.01）. On 50th day, total aerobic, total anaerobic amount and bifidobacterium significantly increased（P〈0.05）. On 70th day, Staphylococcus aureus reduced and lactobacillus increased significantly（P〈0.01）. The intestinal microflora showed an increase in the total aerobic, Clostridium perfringens, enterobacter and enterococcus significantly increased on 20th day（P〈0.05 or 0.01）. Staphylococcus aureus on 50th day increased significantly（P〈0.05）. Total aerobic and enterococcus increased, total anaerobic and Clostridium perfringens reduced significantly on 70th day（P〈0.05 or 0.01）. Conclusions： The microecosystem of respiratory tract and intestine of rat model during the pathological process showed a dynamic disorder, indicating an interaction between the lung and large intestine which may be one of the connotations as they exteriorly and interiorly related.
