Objective To observe the clinical efficacy of self-formulated Shenqi Buwei Decoction(derived from Huangqi Renshen Decoction)in treating patients with stable chronic obstructive pulmonary disease(COPD)differentiated as lung-spleen qi deficiency syndrome.Methods A total of 110 patients with stable COPD differentiated as lung-spleen qi deficiency syndrome were randomly divided into a control group and an observation group,with 55 patients in each group.The control group was given Tiotropium Bromide Inhalation Powder for the inhalation treatment,and the observation group was given Shenqi Buwei Decoction on the basis of treatment for the control group,and the course of treatment covered 3 months.The changes of pulmonary function indicators of forced expiratory volume in one second(FEV1),forced vital capacity(FVC),and one-second rate of FEV1/FVC,modified Medical Research Council index(mMRC)dyspnea scores,6-minute walk test(6MWT),COPD Assessment Test(CAT)scores,and traditional Chinese medicine(TCM)syndrome scores in the two groups were observed before and after treatment.After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)During the trial,one patient was excluded and two patients fell off from the observation group,and three patients fell off from the control group.Eventually,52 patients in each of the two groups were included in the efficacy statistics.(2)After 3 months of treatment,the total effective rate of the observation group was 80.77%(42/52)and that of the control group was 67.31%(35/52).The intergroup comparison(tested by chi-square test)showed that the therapeutic effect of the observation group was slightly superior to that of the control group,but the difference was not statistically significant(P＞0.05).(3)In terms of indexes,After treatment,the levels of pulmonary function indicators of FEV1,FEV1/FVC in the control group and FEV1,FVC,FEV1/FVC in the observation group were significantly improved compared with those before treatment(P＜0.05),and the improvement of FEV1,FVC,FEV1/FVC in the observation group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the 6MWT,mMRC and CAT scores of the two groups were significantly improved compared with those before treatment(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group(P＜0.05).(5)After treatment,the TCM syndrome scores of the two groups of patients were significantly decreased in comparison with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(6)During the treatment process,no obvious adverse reactions occurred in the two groups of patients,there were no abnormal changes in the safety indicators,either.Conclusion On the basis of conventional western medicine treatment,the combined use of Shenqi Buwei Decoction exerts certain efficacy in the treatment of patients with stable COPD differentiated as lung-spleen qi deficiency syndrome.The combined therapy can effectively improve the ventilation function,relieve the clinical symptoms,improve the quality of life and delay the decline of lung function of the patients.

Objective To preliminarily investigate the related factors influencing the size of vestibular schwannomas.Methods The clinical data of patients with vestibular schwannomas who underwent retrosigmoid approach surgery at the department of neurosurgery of First Affiliated Hospital of Xinjiang Medical University from June 2013 to June 2023 were retrospectively analyzed.The tumor size of the patients was evaluated based on their preoperative imaging data.Univariate and multiple linear regression analyses were performed to explore the factors affecting the size of vestibular schwannomas.Results The tumor size of patients was ranging from 0.63 to 6.60 cm,with a median size of 2.97(2.20,3.80)cm.Univariate analysis showed that gender(P=0.010),ethnicity(P=0.001),age(P=0.049)and cystic solid tumor(P<0.001)were related to the size of vestibular schwannomas.Large-sized vestibular schwannomas were most commonly cystic-solid,and small and medium-sized vestibular schwannomas were most commonly solid.BMI,surgical side and place of residence were not correlated with the size of vestibular schwannomas(P>0.05).Multiple linear regression results showed that male(B=0.390,P=0.001)and Uyghur(B=0.611,P<0.001)patients were more likely to develop large tumors;with every 1-year increase in age,the maximum diameter of the tumor was reduced by an average of 0.011 cm(B=-0.011,P=0.027).Conclusion The gender,age,and ethnicity of patients are correlated with the size of vestibular schwannomas,and male,Uyghur,or younger patients were at higher risk of developing larger vestibular schwannomas.

OBJECTIVE: To analyze the report status of outcomes and measurement instruments of randomized controlled trials (RCTs) of acupuncture for post-stroke dysphagia, so as to provide a basis for designing clinical trials and developing the core outcome set in acupuncture for post-stroke dysphagia. METHODS: RCTs of acupuncture for post-stroke dysphagia were searched in databases i.e. CNKI, SinoMed, Wanfang, PubMed, EMbase, Web of Science and clinical trial registries i.e. ClinicalTrials.gov and Chinese Clinical Trial Registry (ChiCTR), from January 1st, 2012 to October 30th, 2021. By literature screening and data extraction, outcomes and measurement instruments were summarized and analyzed. RESULTS: A total of 172 trials (including 165 RCTs and 7 ongoing trials registrations) were included, involving 91 outcomes. The outcomes could be classified into 7 domains according to functional attributes, namely clinical manifestation, physical and chemical examination, quality of life, TCM symptoms/syndromes, long-term prognosis, safety assessment and economic evaluation. It was found that there were various measurements instruments with large differences, inconsistent measurement time point and without discriminatively reporting primary or secondary outcomes. CONCLUSION The status quo of outcomes and measurement instruments of RCTs of acupuncture for post-stroke dysphagia is not conducive to the summary and comparison of each trial's results. Thus, it is suggested to develop a core outcome set for acupuncture for post-stroke dysphagia to improve the normative and research quality of their clinical trial design.

Pruning branches and leaves is the measure to stimulate the growth of Lonicera japonica flower buds, and consequently, the resources of pruned leaves are inevitably and seriously wasted in production. High-performance liquid chromatography(HPLC) was applied for content determination of seven active ingredients(chlorogenic acid, galuteolin, isochlorogenic acids A, B, and C, secologanic acid, and secoxyloganin) in L. japonica leaves from March to November. The results showed that the tillering removed from the trunk of L. japonica in March, the leaves pruned from May to July, and the leaves after the first frost date in November were rich in active ingredients, which deserved further exploitation and utilization. The total content(TC) of active ingredients in pruned L. japonica leaves in early March was the highest. The content of active ingredients in L. japonica leaves increased significantly after the first frost date, which was close to that in the bud tillers pruned in early and middle March. After the first frost date, L. japonica leaves are incapable of photosynthesis, and the harvesting of L. japonica leaves does not affect the physiological activities of the tree. In addition to huge resources, the content of active ingredients is high during this period, which is the best harvesting period of L. japonica leaves.

Objective: To establish a survival prediction model based on the independent prognostic factors of long-term prognosis after laparoscopic liver resection(LLR) for intrahepatic cholangiocarcinoma(ICC). Methods: The clinical and pathological data of 351 consecutive patients with ICC who received radical LLR in 13 Chinese medical centers from August 2010 to May 2021 were collected retrospectively. There were 190 males and 161 females,aged(M(IQR)) 61(14)years(range:23 to 93 years). The total cohort was randomly divided into a training dataset(264 cases) and a validation dataset(87 cases). The patients were followed up by outpatient service or telephone,and the deadline for follow-up was October 2021. Based on the training dataset,the multivariate Cox proportional hazards regression model was used to screen the independent influencing factors of long-term prognosis to construct a Nomogram model. The Nomogram model's discrimination,calibration,and clinical benefit were evaluated through internal and external validation,and an assessment of the overall value of two groups was made through the use of a receiver operating characteristic(ROC) curve. Results: There was no significant difference in clinical and pathological characteristics and long-term survival results between the training and validation datasets(all P>0.05). The multivariate Cox analysis showed that CA19-9,CA125,conversion to laparotomy during laparoscopic surgery,and lymph node metastasis were independent prognostic factors for ICC patients after LLR(all P<0.05). The survival Nomogram was established based on the independent prognostic factors obtained from the above screening. The ROC curve showed that the area under the curve of 1, 3 and 5-year overall survival rates of patients in the training dataset were 0.794(95%CI:0.721 to 0.867),0.728(95%CI:0.618 to 0.839) and 0.799(95%CI:0.670 to 0.928),and those in the validation dataset were 0.787(95%CI:0.660 to 0.915),0.831(95%CI:0.678 to 0.983) and 0.810(95%CI:0.639 to 0.982). Internal and external validation proved that the model exhibited a certain discrimination,calibration,and clinical applicability. Conclusion: The survival Nomogram model based on the independent influencing factors of long-term prognosis after LLR for ICC(including CA19-9,CA125,conversion to laparotomy during laparoscopic surgery,and lymph node metastasis) exhibites a certain differentiation,calibration,and clinical practicability.

Objective:To investigate the effect of Jianpi Bufei prescription （JPBFP） on airway inflammation， airway hyperresponsiveness （AHR）， and cyclic adenosine monophosphate （cAMP） signaling pathway activity in ovalbumin （OVA）-sensitized and challenged juvenile asthma rats. Method:Seventy-five male SD rats were randomly divided into a blank group （n=15） and an experimental group （n=60）. The rats in the experimental group were sensitized by aluminum hydroxide gel containing 0.2% OVA and stimulated by aerosol inhalation of normal saline containing 1% OVA to induce an asthma model， followed by assignment into the following groups： a model group （n=15）， a JPBFP group （n=15， 8.37 g·kg^-1·d^-1）， an aminophylline group （n=15， 40 mg·kg^-1·d^-1）， and a dexamethasone group （n=15， 0.1 mg·kg^-1·d^-1）. AHR was detected by the pulmonary function analyzer， changes in inflammatory cells by white blood cell （WBC） count and differential blood count in bronchoalveolar lavage fluid （BALF）， and pathological changes of lung tissues by hematoxylin-eosin （HE）， Masson， and periodic acid-schiff （PAS） staining. The interleukin （IL）-4， IL-5， IL-13， interferon （IFN）-γ， and tumor necrosis factor （TNF）-α levels in serum and the cAMP level in plasma were tested by the enzyme-linked immunosorbent assay （ELISA）. Protein kinase A （PKA） expression in lung tissues was detected by immunohistochemistry. The cAMP-response element-binding protein （CREB） mRNA and protein expression in lung tissues was detected by the real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot. Result:Compared with the blank group， the model group showed increased lung resistance， decreased pulmonary compliance （P<0.05）， elevated WBC count and proportion of eosinophils in BALF （P<0.05）， up-regulated levels of IL-4， IL-5， IL-13， and TNF-α in peripheral blood， declining IFN-γ level （P<0.01）， severe pathological changes of lung tissues， dwindled cAMP， and down-regulated PKA and CREB expression （P<0.01）. Compared with the model group， JPBFP inhibited AHR， reduced WBC count and proportion of eosinophils in BALF and lung resistance （P<0.05）， improved pathological changes of lung tissues， increased pulmonary compliance， and up-regulated cAMP in serum and PKA and CREB expression in lung tissues （P<0.01）. Conclusion:JPBFP can improve AHR， inhibit airway inflammation， and alleviate lung injury in asthma rats. Its mechanism may be related to the up-regulation of the activity of the cAMP/PKA/CREB signaling pathway.

Objective:To evaluate the effect of Mashao Pingchuan decoction on traditional Chinese medicine （TCM） symptoms， quality of life， peripheral blood eosinophils （Eos） and serum inflammatory factors interleukin-6 （IL-6） and interleukin-8 （IL-8） in patients with cold asthma syndrome of bronchial asthma. Method:A total of 67 patients with cold asthma who attended the Respiratory Clinic of Anhui Provincial Hospital of TCM from January 2018 to December 2019 were selected and randomly divided into a control group and an observation group. The control group was given basic treatments such as budesonide formoterol powder inhalation， and the observation group was given Mashao Pingchuan decoction on the basis of the control group. Both groups intervened for 7 consecutive days. Observe and record the general condition， TCM symptom score， asthma control questionnaire （ACQ）-7 score， Marks-asthma quality of life questionnaire （Marks-AQLQ） score of the two groups of asthma patients， the peripheral blood Eos count was measured by hematology analyzer， and the serum IL-6 and IL-8 levels of the subjects were measured by enzyme-linked immunosorbent assay （ELISA）. Result:The total effective rate of TCM symptoms in the two groups was 100%（30/30）， and the effect in the observation group was more obvious （Z=-2.169，P<0.05）. After treatment， the scores of TCM symptoms in the two groups were significantly lower than those before treatment （P<0.01）. The scores of phlegm in the throat， expectoration， cough， and chills in the observation group were lower than those in the control group （P<0.05）. After treatment， the ACQ-7 scores and Marks-AQLQ scores of the two groups were significantly lower than before treatment （P<0.01）. There was no statistically significant difference between the observation group and the ACQ-7 scores and Marks-AQLQ scores. After treatment， the peripheral blood Eos counts and serum IL-6 and IL-8 levels in the two groups were significantly lower than before treatment （P<0.01）. Peripheral blood Eos count and serum IL-6 and IL-8 contents in observation group were lower than those in control group （P<0.05）. Conclusion:Mashao Pingchuan decoction combined with budesonide formoterol powder inhalation can effectively improve the clinical effectiveness of asthma （cold asthma）， improve the symptoms of asthma in TCM， ACQ-7 score， Marks-AQLQ score， peripheral blood Eos count， serum inflammatory factor content.

Objective:To investigate the molecular mechanism of Qiyu Sanlong prescription （QYSL） in inhibiting the "addiction" of lung cancer A549 cells to miRNA21. Method:The human lung cancer A549 cells were routinely passaged and divided into the blank group， blank serum group， QYSL-containing serum group， and siRNA group. The prepared QYSL-containing serum was used for intervention， with the optimal concentration and action time determined in previous studies. The protein and mRNA expression levels of miRNA21 and related molecules in its target phosphatase and tensin homolog deleted on chromosome 10 （PTEN）/phosphatidylinositol 3-kinase （PI3K） signaling pathway were detected by real-time polymerase chain reaction （Real-time PCR） and Western blot assay. Result:The comparison with the blank serum group revealed that the mRNA expression levels of miRNA21 in the QYSL-containing serum group and the siRNA group were decreased， while the PTEN mRNA expression in the QYSL-containing serum group was increased， showing significant differences （P<0.01）. Compared with the blank serum， the QYSL-containing serum and siRNA significantly down-regulated PI3K and mammalian target of rapamycin （mTOR） mRNA expression （P<0.01）， whereas the QYSL-containing serum did not change the mRNA expression of protein kinase B （Akt）. The protein expression levels of PTEN in the QYSL-containing serum group and the siRNA group were obviously elevated in contrast to that in the blank serum group （P<0.05）. Meanwhile， the protein expression levels of phosphorylated Akt （p-Akt） and phosphorylated mTOR （p-mTOR） evidently declined in the QYSL-containing serum group （P<0.05）， but there was no significant reduction in total Akt and mTOR protein expression. The PI3K protein expression was slightly down-regulated， with no statistical significance. Conclusion:QYSL inhibits the transcription of miRNA21， increases the expression of PTEN， and reduces the expression of key molecules in PI3K/Akt/mTOR signaling pathway， thus mildly inhibiting the "addiction" of lung cancer cells to oncogenes and blocking their proliferation.
