ObjectiveTo observe the clinical efficacy and safety of Guben Quyu Jiedu prescription in treating nocturnal hypoxemia of chronic obstructive pulmonary disease （COPD） combined with Obstructive sleep apnea hypopnea syndrome （ OSAHS ） （deficiency of lung， spleen and kidney with blood stasis and toxicity）. MethodsThe paper used a forward-looking， random double-blind， placebo-controlled design method to select 96 patients with COPD combined with OSAHS， and their traditional Chinese medicines （TCM） syndrome differentiation was deficiency of lung， spleen and kidney with blood stasis and toxicity. These patients were randomly divided into the observation group and the control group， with 48 cases in each group. Based on conventional Western medicine treatment， the observation group was treated with Guben Quyu Jiedu prescription and the control group was treated with traditional Chinese medicine placebo. Both courses of treatment were 90 days. Then the paper compared the changes in minimum pulse oxygen saturation （SpO₂） during the night， apnea index （AHI）， OSAHS efficacy evaluation， TCM syndrome efficacy evaluation， and TCM symptom score before and after treatment between the two groups. ResultsThere were 5 withdrawals in the observation group and 8 withdrawals in the control group， so 43 cases in the observation group and 40 cases in the control group completed the trial. Compared with the condition before treatment， the minimum SpO₂ during the night and AHI in the observation group were significantly improved at night （P<0.01） and were better than those in the control group （P<0.01）. OSAHS efficacy in the observation group was better than in the control group （χ²=7.085， P<0.05）. In terms of TCM syndrome efficacy， the total effective rate was 81.40% （35/43） in the observation group， significantly higher than that in the control group， which was 15.00% （6/40） （χ²=36.78， P<0.01）. The TCM symptom scores of the two groups were improved compared with the condition before treatment， and the effect of the two groups was similar in the four main symptoms of snoring， choking， lethargy， and cough. However， the observation group was better than the control group in 10 details such as dizziness， headache， chest tightness， chest pain， wheezing， dry mouth， and thirst （P<0.05）. ConclusionUsing Guben Quyu Jiedu prescription combined with conventional Western medicine can treat COPD combined with OSAHS hypoxemia at night （deficiency of lung， spleen and kidney with blood stasis and toxicity）. In this way， the minimum pulse oxygen saturation （SpO₂） of patients， the level of disease control， and the quality of life of patients can be improved， and the clinical symptoms can be relieved.

Objective Exploring the therapeutic mechanism of Yishen Jiangzhuo Granules(YSJZG)on chronic kidney disease(CKD)based on mitochondrial dynamics and apoptosis of renal tubular epithelial cells.Methods The CKD model of rats with 5/6 nephrectomy was adopted and divided into 6 groups according to random number table:sham operation control group,model group,emodin group(500 mg/kg/d),Yishen Jiangzhuo granule low,middle and high dose groups.After 8 weeks of treatment with YSJZG,serum creatinine(SCR)and urea nitrogen(BUN),pathological changes of renal cortex,mitochondrial morphology and ultrastructure were detected,and mitochondrial kinetic protein in renal tubular epithelial cells was detected by immunohistochemistry(Drp1,Fis1)and fusion proteins(Opa1,Mfn1)were detected by Western blot,and apoptotic proteins(CytC,Bax)in cytoplasm and mitochondria were detected by real-time PCR.Results Renal injury:Compared with the model group,YSJZG groups significantly reduced the levels of SCR and BUN,renal tubular degeneration and necrosis,and mitochondrial structural damage in rats.Renal tubule mitochondrial dynamic protein:Compared with the model group,the expression of division proteins Drp1 and Fis1 was downregulated,the expression of fusion proteins Opa1 and Mfn1 was upregulated,and transmission electron microscopy observed that the mitochondrial fragmentation changes were relatively mild.Apoptosis related indicators and mtDNA copy number of renal tubular cells:Compared with the model group,the content of Bax protein in renal tubular epithelial cells of YSJZG groups increased significantly in cytoplasm(P<0.05)and decreased significantly in mitochondria(P<0.05).The content of CytC protein decreased significantly in cytoplasm(P<0.05)and increased significantly in mitochondria(P<0.05).The copy number of mtDNA increased significantly(P<0.05),and the total levels of SMAC,CytC and Bax mRNA decreased significantly(P<0.05).Correlation between mitochondrial dynamic protein and apoptosis in renal tubular cells:Pearson correlation analysis showed that the expression of Drp1 and Fis1 was negatively correlated with the expression of CytC in mitochondria,and positively correlated with the expression of CytC in cytoplasm.The expression levels of fusion proteins Opa1 and Mfn1 showed a significant positive correlation with CytC expression in mitochondria,and a significant negative correlation with CytC expression in cytoplasm.Conclusion YSJZG can significantly delay the progression of CKD,and its mechanism may be achieved by regulating mitochondrial dynamics of renal tubular epithelial cells,thereby inhibiting endogenous cell apoptosis pathway.

Objective To investigate the prognostic value of serum P-cadherin( P-cad)level in patients with non-small cell lung cancer(NSCLC). Methods A total of 80 patients with NSCLC in Hanzhong 3201 Hospital of Shaanxi Province from January 2012 to December 2013 were selected as study subjects. The relationships between serum P-cad level and clinicopathological characteristics were analyzed. The Cox regres-sion analysis was used to analyze the risk factors affecting prognosis of NSCLC patients. The survival curve was drawn by Kaplan-Meier method and the difference test was carried out by log-rank method. Results There were significant differences in lymph node metastasis(χ2 = 14. 31,P < 0. 001),vascular invasion(χ2 = 5. 56, P = 0. 018)among NSCLC patients with different levels of serum P-cad. Multivariate Cox regression analysis showed that lymph node metastasis(HR = 0. 856,95％ CI:0. 702-0. 955,P = 0. 012),TNM stage(ⅢA HR =1. 315,95％ CI:1. 058-1. 991,P = 0. 024;ⅢB HR = 1. 448,95％ CI:1. 124-2. 215,P = 0. 011;Ⅳ HR =1. 569,95％ CI:1. 182-2. 441,P < 0. 001)and high level of serum P-cad(HR = 1. 815,95％ CI:1. 224-3. 562,P < 0. 001)were risk factors for progression-free survival in NSCLC patients,and lymph node metasta-sis(HR = 0. 755,95％ CI:0. 652-0. 915,P = 0. 022),poor differentiation(HR = 1. 622,95％ CI:1. 112-2. 015,P < 0. 001),TNM stage(ⅢA HR = 1. 335,95％ CI:1. 064-2. 014,P = 0. 011;ⅢB HR = 1. 489, 95％ CI:1. 129-2. 297,P < 0. 001;Ⅳ HR = 1. 622,95％ CI:1. 192-2. 501,P < 0. 001)and high level of serum P-cad(HR = 1. 677,95％ CI:1. 193-2. 668,P < 0. 001)were risk factors for overall survival of NSCLC patients. The results of Kaplan-Meier survival curve showed that the overall survival and progression-free survival of patients with high level of serum P-cad were shorter than those of patients with low level of serum P-cad(χ2 = 5. 18,P = 0. 015;χ2 = 5. 48,P = 0. 011). Conclusion High level of serum P-cad is closely related to poor prognosis in NSCLC patients.

Objective To investingate the effect of SGK1 expression level on the prognosis of patients with NSCLC,and provide new biological predictors for the prognosis assessment of patients with NSCLS.Methods One hundred and twenty patients with NSCLC received radical resection in Hanzhong 3201 hospital from Jan 2011 to Dec 2013 were selected.There were 75 males and 45 females,age (63.15 ± 16.44) years,age range 45-80 years.According to the results of immunohistochemical staining,the SGK1 cut-off value determined by the integral was determined,and NSCLC patients were divided into SGK1 high expression group (n =70) and SGK1 low expression group(n =50).The relationship between the expression of SGK1 and clinicopathological features (age,sex,smoking history,alcoholism history,BMI,tissue type,tumor diameter,T stage,N stage,TNM stage,differentiation degree) in NSCLC were analyzed,and the overall survival rate in NSCLC were also analyzed.Followup was carried out by telephone or patient admission.The follow-up period was up to June 1,2018.Chest X-ray and ultrasonography were reviewed every 3 to 6 months after operation,and enhanced CT or MRI were performed if the results were abnormal.The measurement data conforming to normal distribution were expressed by t test and showed by (Mean ± SD);the counting data were tested by x2 test;the 5-year overall survival rate was used as the endpoint event for univariate analysis,and the significant variables for univariate analysis were analyzed by COX risk ratio model for multivariate analysis.The cumulative survival curve was drawn by Kaplan-Meier method,and the difference was tested by Log-rank method.Results The expression level of SGK1 in tissues was not related to age,sex,smoking history,alcoholism,BMI,tissue type and tumor diameter (P ＞ 0.05),but it was related to T stage,N stage,TNM stage and differentiation degree (P ＜ 0.05).The univariate and multivariate COX risk ratio model showed that TNM stage and SGK1 expression were independent factors affecting the 5-year overall survival rate of NSCLC patients (P ＜ 0.05).The results of Kaplan-Meier survival curve showed that the 5-year overall survival rate in NSCLC with low expression of SGK1 was significantly higher than that in NSCLC with high expression of SGK1 (P ＜ 0.05).Conclusions The expression of SGK1 in tissues is closely related to the prognosis of patients with NSCLC.The high expression of SGK1 in tissues is not conducive to the prognosis of patients with NSCLC.

Objective To observe the clinical efficacy of Shiwei Longdanhua Capsule combined with western medicine on patients with mild acute exacerbation of chronic obstructive pulmonary disease (COPD) with phlegm-heat obstructing lung syndrome. Methods Totally 192 cases of COPD with mild acute exacerbation (phlegm-heat obstructing lung syndrome) were recruited. They were randomly divided into the treatment group (96 cases) and the control group (96 cases). Patients in the control group were treated in line with the regular Western treatment, while patients in the treatment group were additionally treated by Shiwei Longdanhua Capsule. After 10-day treatment, the changes of TCM syndrome score, symptom integral and the lung function before and after treatment were compared. Results After treatment, 14 patients withdrew from the treatment group and 15 patients withdrew from the control group. The total efficiency rate of TCM syndrome was 80.49% (66/82) in the treatment group, while it was 56.79% (46/81) in the control group, with statistical difference between the two groups (P<0.05). The severity and frequency of cough and expectoration of the treatment group were better than the control group (P<0.05). The breathing symptom and pulmonary function of patients in the two groups improved, with similar efficacy. Conclusion The efficiency of Shiwei Longdanhua Capsule combined with Western medicine in the treatment of acute exacerbation of COPD is superior to that of simple Western medicine treatment, especially in terms of relieving cough and expectoration.

Objective To observe the Clinical effects on Sanao tables combined with Montelukast Tables for cough variant asthma (CVA) (cold beam lung card).Methods Eighty-nine cases of sydrome differentiation (cold beam lung card) complied with CVA diagnostic criteria were randomly divided into treatment group (45 cases,3 cases were lost) and control group(44 cases,4 cases were lost)).The treatment group was given oral San'ao tables combined with Montelukast tables,and the control group was given oral Montelukast tables.The course of treatment were all 14 days.Chinese medical syndrome,cardinal symptom and airway reactivity effects were determined and compared at pretherapy.Results Clinical effects of Chinese medical syndrome (effective rate (90.48％,38/42),cough severity (85.71％,36/42),frequency (90.48％,38/42),cough up phlegm (85.71％,36/42),pharyngeal itching (80.95％,4/42) and aversion to cold (76.19％,32/ 42)) in treatment group were all superior to control group (70.00％ (28/40),62.50％ (25/40),70.00％ (28/ 40),55.00％ (22/40),52.50％ (21/40),25.00％ (10/40)).The differences were statistical significance (x2=14.046,14.046,13.923,23.104,17.729,17.729;P＜0.05 or P＜0.01).Conclusion Clinical effects of San' ao tables combined with Montelukast tables on CVA is superior to Montelukast tables.

ObjectiveTo compare three types of acute Mycobacterium tuberculosis infection mouse models established through different infection routes and to set up the theoretical basis for further developing,selecting and applying these animal model in the tuberculosis-related research.MethodsStandard strain of Tubercle bacillus H37Rv was diluted to 1 × 106 colony forming unit (cfu)/mL.The mice were infected with the bacteria through different routes including intravenous injection,intranasal administration and inhalation of bacteria aerosol.Six weeks after the infection,the mice were euthaniz ed and necropsied. The lung tissues were collected and gross changes were observed.The colony counting was performed and the lung tissues were assessed by HE staining,acid fast staining.The e xpression level of tumor necrosis factor (TNF)-α per unit area in lung tissue was detected by immunohistochemistry. The data were analyzed by t test. Results The amounts of Mycobacterium tuberculosis in lung tissues of mice in inhalation group,intranasal administration group and intravenous injection group were (6.290±0.028),(6.150±0.021) and (6.120±0.008) lg cfu/mL,respectively; while no Mycobacterium tuberculosis was detected in control group. The difference between infection group and control group was statistically significant (t =3.762,P＜0.01),while there were no significant differences among infection groups with different infection routes (P＞0.05).According to the results of gross observations and histological assessment,the pathological changes were observed and red tubercle bacillus was detected by acid-fast staining in the lung tissues of all the mice in infection group.The results of immunohistochemistry showed that the expression levels of TNF-α per unit area were as follows:intravenous injection group (0.049 × 106 )＜intranasal administration group(0.759×106) ＜ inhalationgroup(1.042×106), whichwere statistically different (t =2.504,P＜ 0.05).ConclusionInhalation of bacteria aerosol may be the most efficient method to establish tuberculosis infection mouse model compared to intravenous injection and intranasal administration.
