ObjectiveTo explore the effect of Tanreqing injection combined with Ceftazide on the clinical efficacy， lung function， and laboratory inflammatory index of patients suffering from phlegm heat obstructing lung syndrome in acute exacerbation of chronic obstructive pulmonary disease （AECOPD）. MethodFrom June 2021 to June 2023， 76 patients diagnosed with phlegm heat obstructing lung syndrome in AECOPD were enrolled in the respiratory and critical medical department of Jieshou Hospital of Traditional Chinese Medicine. They were randomly divided into a control group and an observation group with 38 cases each. The control group used Ceftazidime intravenous drip and other conventional oxygen inhalation and antispasmodic treatment measures of western medicine. The observation group received Tanreqing injection intravenous drip based on the treatment of the control group， with a course of 10 days. The changes of laboratory indicators such as hs-CRP， calcitonin （PCT）， and interleukin-6 （IL-6） before and after treatment were analyzed， and the improvement of forced expiratory volume in the first second （FEV1）， forced vital capacity （FVC）， one second rate （FEV1/FVC）， assessment and improvement of the British Medical Research Society’s dyspnea index （mMRC）， self-evaluation test of chronic obstructive pulmonary disease patients （CAT）， and traditional Chinese medicine syndrome score was compared. In addition， the total effective rate between the two groups after treatment was compared. ResultAfter treatment， the hs-CRP， PCT， IL-6， FEV1， FVC， FEV1/FVC， mMRC， CAT scores， and traditional Chinese medicine syndrome evaluation of both groups improved （P<0.01）. After treatment， compared with the control group， the observation group showed more significant improvements in hs-CRP， PCT， IL-6， FEV1， FVC， FEV1/FVC， mMRC， CAT scores， and traditional Chinese medicine syndrome evaluation， and the difference was statistically significant （P<0.05，P<0.01）. The total clinical effective rate of the control group was 86.84% （33/38）， while that of the observation group was 94.74% （36/38）. The therapeutic effect of the observation group was better than that of the control group （χ2=8.471， P<0.05）. ConclusionTanreqing injection combined with Ceftazidime has obvious efficacy in the treatment of phlegm heat obstructing lung syndrome in AECOPD， which is better than the treatment of Ceftazidime antibiotics alone. It can reduce the risk of acute exacerbation， alleviate clinical symptoms， and delay the decline of lung function.

Establishment and Evaluation of Rat Model for Chronic Obstructive Pulmonary Disease with Lung-spleen Qi Deficiency / 中国实验方剂学杂志

ObjectiveTo establish and evaluate a chronic obstructive pulmonary disease （COPD） model with lung-spleen qi deficiency. MethodA rat model mimicking COPD with lung-spleen qi deficiency was established by the combination of cigarette smoking and intratracheal instillation of lipopolysaccharide （LPS） along with gavage of Sennae Folium infusion. Forty male SPF-grade SD rats were randomly assigned to blank， model， and low- （L-FXY）， medium- （M-FXY）， and high-dose （H-FXY） Sennae Folium infusion groups. Other groups except the blank group were exposed to daily cigarette smoke， with LPS administrated via intratracheal instillation on the 1st and 14th days. On the 28th day of modeling， the L-FXY， M-FXY， and H-FXY groups were administrated with Sennae Folium infusion at 5， 10， and 20 g·kg-1， respectively， and at 4 ℃ for three weeks. The modeling lasted for 49 days. The general conditions （body mass， food intake， fecal water content， and anal temperature） and behaviors （grip strength test and tail suspension test） of rats in different groups were examined. The lung function， lung histopathology， D-xylose， amylase， and gastrin levels in the serum， interleukin（IL）-1β and IL-6 levels in the alveolar lavage fluid， levels of T-lymphocyte subsets （CD4+， CD8+， and CD4+/CD8+） in the peripheral blood， and thymus and spleen indices were measured. ResultTwo rats died in the H-FXY group. Compared with the blank group， both the M-FXY and H-FXY groups exhibited reduced body mass and food intake （P<0.01） and increased fecal water content （P<0.01）. The anal temperature in the H-FXY group was lower than that in the blank group （P<0.01）. The grip strength decreased in the modeling groups compared with the blank group （P<0.01）， and the duration of immobility in the tail suspension test increased in the M-FXY and H-FXY groups （P<0.05， P<0.01）. Compared with the blank group， the modeling groups showed reduced 0.3 second forced expiratory volume （FEV0.3）， FEV0.3/forced vital capacity （FVC）（P<0.01）， thickening of bronchial walls， proliferation of goblet cells， and the presence of emphysematous changes. In terms of gastrointestinal function， the M-FXY and H-FXY groups had lower levels of D-xylose， gastrin， and α-amylase than the blank group （P<0.01）. Regarding the immune and inflammatory indices， the M-FXY and H-FXY groups showed lower thymus and spleen indices than the blank group （P<0.01）. Compared with the blank group， the modeling groups presented lowered CD4+ level （P<0.01） and CD4+/CD8+ ratio （P<0.05， P<0.01） in the peripheral blood and elevated levels of IL-1β and IL-6 in the alveolar lavage fluid （P<0.01） than the blank group. ConclusionA model of COPD with lung-spleen Qi deficiency was established through the combination of daily cigarette smoke， intratracheal instillation with LPS， and gavage of Sennae Folium infusion. The comprehensive evaluation results suggested medium-dose （10 g·kg-1） Sennae Folium infusion for gavage during the modeling of COPD with lung-spleen Qi deficiency.

The dynamic metabolic profile of Qi-Yu-San-Long decoction in rat urine using UPLC-QTOF-MSE coupled with a post-targeted screening strategy / 药物分析学报

Qi-Yu-San-Long decoction(QYSLD)is a traditional Chinese medicine that has been clinically used in the treatment of non-small-cell lung cancer(NSCLC)for more than 20 years.However,to date,metabolic-related studies on QYSLD have not been performed.In this study,a post-targeted screening strategy based on ultra-performance liquid chromatography coupled with quadrupole time-of-flight full infor-mation tandem mass spectrometry(UPLC-QTOF-MSE)was developed to identify QYSLD-related xeno-biotics in rat urine.The chemical compound database of QYSLD constituents was established from previous research,and metabolites related to these compounds were predicted in combination with their possible metabolic pathways.The metabolites were identified by extracted ion chromatograms using predicted m/z values as well as retention time,excimer ions,and fragmentation behavior.Overall,85 QYSLD-related xenobiotics(20 prototype compounds and 65 metabolites)were characterized from rat urine.The main metabolic reactions and elimination features of QYSLD included oxidation,reduction,decarboxylation,hydrolysis,demethylation,glucuronidation,sulfation,methylation,deglycosylation,acetylation,and associated combination reactions.Of the identified molecules,14 prototype compounds and 58 metabolites were slowly eliminated,thus accumulating in vivo over an extended period,while five prototypes and two metabolites were present in vivo for a short duration.Furthermore,one pro-totype and five metabolites underwent the process of"appearing-disappearing-reappearing"in vivo.Overall,the metabolic profile and characteristics of QYSLD in rat urine were determined,which is useful in elucidating the active components of the decoction in vivo,thus providing the basis for studying its mechanism of action.

Objective To observe the clinical effect of traditional Chinese medicine (TCM) characteristic lung rehabilitation in treatment of patients with chronic obstructive pulmonary disease (COPD) and TCM syndrome of lung and kidney qi deficiency at stable period. Methods Sixty patients with stable COPD and lung and kidney qi deficiency syndrome admitted to the First Affiliated Hospital of Anhui University of Chinese Medicine from June to August 2017 were enrolled, and they were divided into routine treatment group and lung rehabilitation treatment group according to the random number table method, each group 30 cases. The routine treatment group was given Seretide (serevent/futicasone) dry powderi nhalation therapy; on the basis of therapy in the routine treatment group, the lung rehabilitation treatment group was treated with TCM characteristic lung rehabilitation technology (acupoint application + Chinese medicine ionic induction + oral administration of Chinese medicine Liuweibuqi granules, delivery at appropriate intervals); both groups were treated for 2 months. The changes of TCM syndrome score, western medicine symptom score, the times of acute exacerbation of COPD, COPD assessment test (CAT) score, lung function indexes: forced expiratory volume in one second (FEV1), FEV1/forced vital capacity (FVC) were observed before and after treatment in two groups. Results After treatment, TCM syndrome score, western medicine symptom score, CAT score, and after treatment the times of acute exacerbation of COPD in both groups were significantly lower than those before treatment, and the above indexes in the lung rehabilitation treatment group were markedly lower than those in routine treatment group [TCM syndrome score:11.93±1.80 vs. 14.27±2.88, western medicine symptom score: 14.20±2.75 vs. 11.93±4.23, CAT score: 14.87±2.60 vs. 16.23±4.39, the times of acute exacerbation of COPD (times): 0.63±0.49 vs. 0.95±0.83, all P < 0.05]. The improvement of FEV1 in the two groups was not significant; but FEV1/FVC in lung rehabilitation treatment group was obviously higher than that before treatment, FEV1/FVC in lung rehabilitation treatment group was significantly higher than that in the routine treatment group [(57.93±7.27)% vs. (52.49±6.61)%, P < 0.05]. Conclusion The application of TCM characteristic lung rehabilitation in the treatment of COPD patients with stable lung and kidney qi deficiency syndrome based on bronchodilators and glucocorticoids can reduce the number of acute exacerbation, improve the patients' clinical symptoms and living quality, but the improvement of lung function is not significant.

Effects of Qibaipingfei capsules on pulmonary vascular relaxation through KATP channel activation by the NO cGMP signaling pathway

This research explores the effects of Qibaipingfei [QBPF] capsules on pulmonary vascular relaxation in vitro and the relationship of the ATP-sensitive K+ [KATP] channel and nitric oxide [NO] pathway. Vasodilator effects of QBPF [0.125-2 g/kg] on rat pulmonary artery rings were observed using a multi-wire myograph system. The maximum relaxation [Emax] of QBPF was detected following treatment involving endothelial denudation, N omega-nitro-L-arginine methyl ester [L-NAME], 1H-[1,2,4] oxadiazolo[4,3-alpha]quinoxalin-1-one [ODQ], or glyburide [GLYB]. Furthermore, rat models of phlegm and blood stasis syndrome combined with chronic obstructive pulmonary disease [COPD] were established using compound factors. KIR6.1 and SUR2B protein expression was analyzed by western blotting. After 9,11-dideoxy-11alpha,9alpha-epoxy-methanoprostaglandinF2alpha [U46619] was used to pre-constrict endothelium-intact pulmonary artery rings, QBPF induced the effects of concentration-dependent relaxation at a concentration for 50% of maximal effect [EC50] of 0.56 g/L and Emax of 84.30% +/- 6.27%. After the endothelium was denuded, the vasodilator effects reduced significantly [P<0.01]. QBPF-induced relaxation was inhibited by L-NAME, ODQ, and GLYB [P<0.01]. The vasodilator effect was also attenuated in the model group [Emax=62.63% +/- 10.02, EC50 = 0.72 g/L, P<0.01]. In comparison with expression in the control group, SUR2B protein expression was down-regulated in the model group [P<0.01] but no significant difference was detected in KIR6.1 protein expression between the groups [P>0.05]. QBPF and nicorandil [Nic] treatment up-regulated SUR2B KATP channel expression [P<0.05]. QBPF induces endothelial-dependent relaxation in pulmonary artery rings in vitro, through a mechanism that potentially activates the KATP channel in pulmonary vascular smooth muscles via the NO-cyclic GMP [cGMP]-dependent pathway

Effects of Qibai Pingfei Capsules on Up-regulating Expression of 5-HT1AR mRNA, DA-1 and DA-5 in Hippocampus of Rat Model with COPD Accompanied with Depression / 广州中医药大学学报

Objective To investigate the effects of Qibai Pingfei Capsules(QPC) on the expression of monoamine neurotransmitters of 5-hydroxytryptamine receptor(5-HT) and dopamine(DA) receptors of DA1 and DA5 in the rats with chronic obstructive pulmonary disease (COPD) accompanied with depression, and to explore the possible therapeutic mechanism. Methods Ninety male Wistar rats were randomly divided into 6 groups, namely normal group, COPD depression group, QPC group, Venlafaxine group, and QPC plus Venlafaxine group. The rat model of COPD accompanied with depression was established by compound methods of smoking, food deprivation, water deprivation, forced swimming, shaking, and clipping tail. And then the effects of QPC on the lung function and the general characteristics were observed. Furthermore, the mRNA level of 5-HT1AR was determined by real-time quantitative reverse transcription PCR(RT-qPCR), and protein levels of DA-1 and DA-5 in rat hippocampus were assayed by Western blot analysis. Results Compared with the normal group, forced expiratory volume in 0.3 second(FEV0.3), the forced volume capacity(FVC) and FEV0.3/ FVC in the COPD depression group were significantly reduced (P < 0.01). Compared with the COPD depression group, the values mentioned above were restored to different extents in the groups of QPC, Venlafaxine, and QPC plus Venlafaxine(P<0.01). Compared with the normal group, the expression levels of 5-HT1AR mRNA, and DA-1 and DA-5 protein in the COPD depression group were significantly down-regulated, and their levels were also slightly decreased in the treatment groups(P<0.05). Compared with the COPD depression group, the expression levels were up-regulated to various degrees in all of the treatment groups (P < 0.05). Conclusion QPC can increase the mRNA levels of 5-HT1AR and protein levels of DA-1 and DA-5 in the hippocampus of COPD with depression.

Objective To observe the effects of Liuwei Buqi capsules on CD4+CD25+forkhead box protein 3+(Foxp3+)regulatory T cells(Tregs),helper T cells(Ths)in patients with chronic obstructive pulmonary disease (COPD). Methods Eighty COPD patients admitted into the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from January 2012 to May 2013 were randomly divided into a traditional Chinese medicine (TCM)experimental group(40 cases)and a western medicine control group(40 cases);there were 40 research volunteers enrolled as healthy controls. After admission,both the TCM experimental group and western medicine control group were given conventional western medicine comprehensive treatment. Additionally,in the TCM experimental group,Liuwei Buqi capsules were given orally once 3 pills(0.4 g/pill)and twice a day,while in the western medicine control group nifedipine was given,once 10 mg and 3 times a day,30 days constituting one therapeutic course for both groups. BODE evaluation means that the body mass index(B),the degree of airflow obstruction(O),the scores of dyspnea(D)and excercise capacity(E)of COPD patients were evaluated. A spirometer was used to observe the changes in the patient's pulmonary function to detect the dyspnea score. The γ-interferon(IFN-γ),interleukin (IL-4 and IL-17)in serum were detected by enzyme-linked immunosorbent assay(ELISA). The expression of Treg of peripheral blood was detected by flow cytometry. Results Compared with healthy control group,lung function parameters,IL-4,CD4+CD25+Treg and CD4+CD25+Foxp3+Treg of peripheral blood were increased,while dyspnea score,BODE score,the expressions of IFN-γ,Th1/Th2,IL-17 in serum were decreased significantly in the COPD group(P<0.05 or P<0.01). After treatment,compared with those before treatment in the two groups, the forced expiratory volume in 1 second(FEV1),FEV1/forced vital capacity(FVC),IL-4,CD4+CD25+Treg, CD4+CD25+Foxp3+ Treg were all increased,while dyspnea score,BODE score,IFN-γ,Th1/Th2,IL-17 were all decreased(P<0.05 or P<0.01),and the peak expiratory flow(PEF)was decreased in western medicine control group and increased in TCM experimental group. After treatment,the comparisons of ratio of FEV1/FVC〔(78.12±14.96)%vs.(67.52±10.39)%〕,BODE score(1.07±0.72 vs. 1.77±0.74),IL-17(μg/L:40.80±8.97 vs. 48.22±6.51) Th1/Th2(1.05±0.23 vs. 1.42±0.21)and CD4+CD25+Foxp3+ Treg〔(6.61±2.26)% vs.(5.25±2.03)%〕between the two groups were all of statistical significant difference(all P<0.05). Conclusion Liuwei Buqi capsules can improve COPD symptoms by up-regulating the expressions of CD4+CD25+Foxp3+ Treg,IL-4,and down-regulating the expressions of IFN-γ,IL-17 to correct the balance of Th1/Th2 in patients with COPD.

Cardiopulmonary Related Index Change of Diffusing the Lung and Promoting Urination on Cor Pulmonale Rats / 世界科学技术-中医药现代化

This study was aimed to diffuse the lung and promote urination for the observation of cardiopulmonary re-lated index change of cor pulmonale rats to further explore the treatment effect on the pulmonary function, pulmonary arterial hypertension (PAH) and the influence of right heart hypertrophy of rats, in order to further illustrate the ef-fect of diffusing the lung and promoting urination for cor pulmonale. Sixty Wistar rats were randomly divided into the control group, model group and Xiao-Qing-Long decoction (XQLD) group with 20 rats in each group. The AniRes2003 animal lung function analysis system was applied to measure the pulmonary function of rats. And the multi-guide physiological recorder was used in the recording of the pulmonary artery pressure of rats. The conven-tional weighing method was applied to calculate and obtain the change of right heart hypertrophy. The results showed that compared to the control group, symptoms in the model group became severe obviously, which include reduced activity, slow movement and occasional airway sputum sound, and the right heart hypertrophy index of the model group increased obviously (P < 0.01). Compared to the model group, the pulmonary function and pulmonary artery pressure of the XQLD group have obvious difference (P< 0.05). It was concluded that to diffuse the lung and pro-mote urination can effectively improve the pulmonary function, PAH and the right heart hypertrophy index of rats with cor pulmonale (fluid retention). The effect of this method is definite in the treatment of cor pulmonale.

Observation on the curative effect of Qufengqingre method in treatment of the patients with cough after cold / 中国基层医药

ObjectiveTo explore the curative effect of Qufengqingre method in treatment of the patients with cough after cold.Methods74 patients with cough after cold were selected and randomly divided into the control group(36 cases) and the observation group (38 cases ).The control group was given roxithromycin (150 mg every time,two times every day),ketotifen( 1 mg every time,one time every night),pentoxyverine citrate(50mg every time,3 times every day).The observation group was given Qufengqingre decoction,and the decoction was boiled in water twice per dose,and mixed juice about 300 ml was abtained for morning and evening oralling.The efficacy,symptoms score and adverse reactions were observed.ResultsIn the control group,7 patients were cured,effective in 21 cases,invalid in 8 cases,and in the observation group,17 cases were cured,effective in 18 cases,invalid in 3 cases.The total effective rate of the observation group was 92.1％ higher than 77.8 ％ of the control group ( x2 =4.16,P ＜ 0.05 ).The cough and sputum score of the two groups before treatment was ( 2.18 ± 0.73 ) points and ( 1.09 ± 0.27 ) points,(2.26 ± 0.65 ) points and ( 1.12 ± 0.23 ) points,respectively,and after treatment was ( 1.11 ± 0.37 ) points and (0.65 ± 0.16) points,(0.72 ± 0.19 ) points and (0.35 ± 0.08 ) points.Differences in scores between the two groups before treatment were not statistically significant(t =1.29,1.31,all P ＞ 0.05 ) ; In the two groups before and after treatment were statistically significant( t =2.68,2.59,2.43,2.41,all P ＜ 0.05 ) ; After treatment the difference between the two groups were statistically significant( t =2.53,2.37,all P ＜ 0.05 ).Both groups had no obviously adverse reactions.ConclusionQufengqingre method in treatment of the patients with cough after cold had remarkable effect.
