Objective To evaluate the therapeutic effect and safety of Huangqi Danshen Drop Pill (HDP) for angina pectoris (AP) due to coronary heart disease (CHD) classified as qi- deficiency and blood- stasis syndrome. Methods A multi- center, randomized, double- blind, double- simulation, positive- controlled, parallel group trial was adopted. 209 cases of AP due to CHD classified as qi- deficiency and blood- stasis syndrome were enrolled in this study: 104 in HDP group and 105 in Yangxinshi Tablets group. Results The markedly effective rate was 43.27 % , total effective rate 86.53 % , and total effective rate in improving TCM symptoms 92.31 % in HDP group, which were better than those in Yangxinshi Tablets group(P

Objective To evaluate the safety and efficacy of Safflower Yellow Injection(SYI)in treating coronary heart disease and angina pectoris(CHD-AP)with heart blood stagnation syndrome(HBSS).Methods A randomized,positive parallel contral and multi-center clinical trial was adopted.The SYI injection group was treated with SYI and Xiangdan injection group with Xiangdan injection by intravenous dripping for 2 weeks.Results The efficacy on angina pectoris,electrocardiogram,and traditional Chinese medicine(TCM)syndrome in SYI injection group was superior to that in Xiangdan injection group,showing significant differences(P

Objective To investigate the significance of K-ras gene status and ras protein expression in immunophenotypic classification of gastric signet ring cell carcinoma.Methods The expression of ras protein in 180 cases of gastric signet-ring cell carcinoma was detected by tissue microarray immunohistochemistry.Meanwhile,the mutation in codon 12,13 of K-ras gene was determined by using PCR-based DNA direct sequencing analysis.Results The rate of ras protein expression was 27.8％.The rate of ras protein expression in intestinal phenotype was significantly higher than those in gastric and gastrointestinal phenotypes(P<0.05).The rate of ras protein expression in cases with lymph node metastasis was significantly higher than those in cases without nodal involvement(P<0.05).The rate of ras protein expression was significantly higher in cases with deeper invasion(P<0.05).The frequency of K-ras gene mutation was 22(12.2％).All of them were found in codon 12.The types of mutation included GGT→AGT(1 case),GGT→TGT(1 case),GGT→GCT(2 cases),GGT→GTT(8 cases)and GGT→GAT(10 cases).K-ras mutation was significantly associated with intestinal phenotype(P<0.05).The rates of ras protein expression in cases with mutational type of K-ras gene was higher than those in cases with wild type(P<0.05).The ras protein expression was positively associated with K-ras gene mutation(r=0.61,P<0.05).Conclusion The ras protein expression is correlated with nodal involvement and invasion.K-ras gene mutation and expression of ras protein is related to phenotypic classification,and they might influence the phenotypic transformation in gastric signet ring cell carcinoma.

Objective To know the stability of 3 kinds of traditional Chinese drug injection with different solvent under different temperature and different storage time,and then reference to safty of clinical durgs. Methods Use particle analyzer,UV SpectropHotometer,pH Determination of three traditional Chinese medicine injection,at different temperatures and different times,the nuanber of particles,pH value,the value of UV absorbance Observe changes. Results The records of experimental data by repeated measures analysis of statistics: Ciwujia Injection,Aidi injection combined with normal saline solution after the particles of ≥ 10μm excess pharmacopoeia standards; ≥ 2μm number of particles is considerable,in the 32～35℃,Ciwujia at T=O min Aidi at T=I80 min ,the number of particles are smaller and with statistical significance,its pH value of the standard range. Xuesaitong injection with glucose injection ≥ 10μm particulate mixture at a higher temperature in excess of pH annacopoeia standards,number of ≥ 2 μm particles in the 4～8℃ and 20～23℃,T=30 min and 60 min time less with statistical significance,and its range of pH value less than pHarmacopoeia. Three kinds of Chinese medicine in the Department's largest UV absorbance peak value and appearance almost unchanged. Conclusions Different drugs in their relative Suggestions of temperature,time and place under intravenous drug use,or better terminal filter,in order to improve the safety of clinical medication.

Objective To investigate the clinical value of prophylactic high-flow nasal cannula oxygen therapy (HFNC) in reducing postoperative pulmonary complication (PPC) in elderly patients with non-small cell lung cancer (NSCLC). Methods The clinical data of elderly patients (over 60 years) with NSCLC who underwent video-assisted thoracoscopic lobectomy or segmental resection at the Department of Thoracic Surgery, Fujian Provincial Hospital from January 2021 to March 2022 were retrospectively analyzed. According to whether receiving HFNC after surgery, they were divided into a conventional oxygen therapy (CO) group and a HFNC group. The CO group were matched with the HFNC group by the propensity score matching method at a ratio of 1 : 1. We compared PPC incidence, white blood cell (WBC) count, procalcitonin and C-reactive protein on postoperative day (POD) 1, 3 and 5 and postoperative hospital stay between the two groups. Results A total of 343 patients (165 males, 178 females, average age of 67.25±4.79 years) were enrolled, with 53 (15.45%) receiving HFNC. Before matching, there were statistical differences in gender, rate of combined chronic obstructive pulmonary disease, pathology type and TNM stage between the two groups (all P<0.05). There were 42 patients successfully matched in each of the two groups, with no statistical difference in baseline characteristics (P>0.05). After propensity score matching, the results showed that the PPC incidence in the HFNC group was lower than that in the CO group (23.81% vs. 45.23%, P=0.039). WBC count on POD 3 and 5 and procalcitonin level on POD 3 were less or lower in the HFNC group than those in the CO group [ (8.92±2.91)×109/L vs. (10.62±2.67)×109/L; (7.68±1.58)×109/L vs. (8.86±1.76)×109/L; 0.26 (0.25, 0.44) μg/L vs. 0.31 (0.25, 0.86) μg/L; all P<0.05]. There was no statistical difference in the other inflammatory indexes or the postoperative hospital stay between the two groups (P>0.05). Conclusion Prophylactic HFNC can reduce the PPC incidence and postoperative inflammatory indexes in elderly patients with NSCLC, but does not shorten the postoperative hospital stay.
