ABSTRACT
Objective Broth dilution method was used as a reference method to observe the capability of Kirby-Bauer disc diffusion assay(K-B)for correcting automated ampicillin susceptibility detection of He-mophilus influenzae(HI).Methods A total of 228 HI strains isolated were collected,broth dilution assay,K-B and automated microdilution broth test(ATB)were used to determine the susceptibility of HI to ampicillin. Analyze the essential agreements of the three methods and the correction of K-B to the errors of A TB. Results The essential agreement of K-B or ATB with broth dilution method were 77.19%,70.18% respec-tively,combination of K-B and ATB could make the essential agreement increase up to 86.0%,which was sig-nificantly higher than ATB(χ2=16.600,P=0.000).Major error of ATB(42.0%)was higher than that of K-B(10.0%)(χ2=13.306,P=0.001),but very major error and minor error showed no significant difference be-tween the two methods(χ2=1.208,P=0.272;χ2=1.182,P=0.227),meanwhile,76.19% of major error of ATB could be corrected by K-B.For the very major error of ATB,53.57% could be corrected by K-B.Howev-er,the corrective capability of K-B to minor error of ATB was relative low.Conclusion K-B test could correct some errors generated by ATB.For the β-lactamase negative strains which were judged as ampicillin resistance by A TB,K-B test should be used to correct the errors by ATB.Moreover,it is necessary to apply K-B to confirm am-picillin sensitivity of the β-lactamase positive strains which were judged as ampicillin susceptible by ATB.
ABSTRACT
The consecutive data of 822 senior public officials in Chengdu undergoing health checkup from 2011 to 2016 were retrospectively reviewed.Among them,56 new cases of diabetes was diagnosed with a cumulative incidence of 6.81％.Fifty six age-and sex-matched healthy subjects served as controls,the risk factors of new-onset diabetes were analyzed with multivariate logistic regression.The results showed that BMI (OR =1.82,95％ CI:1.27-2.59,P =0.00) and fasting plasma glucose (OR =13.63,95％ CI:2.71-68.43,P =0.00) were independent risk factors of new-onset diabetes in senior public officials.
ABSTRACT
Objective To explore the efficacy ofTiaogan-Bushen-Xiaoji recipe (TGBSXJ Recipe) on overall survival and progression free survival (PFS) in patients with advanced breast cancer.Methods A total of 105 patients with advanced breast cancer, who received the first-line treatment, were divided into two groups, 56 cases in the control group and 49 in the experimental group. The control group received standard therapy according to guidelines, including chemotherapy, targeted therapy, endocrine therapy and treatment of bisphosphonates.The experimental group received the treatment of TGBSXJ Recipe besides the standard therapy. The overall survival (OS), progression-free survival (PFS) and Karnofsky (KPS) of the patients in two groups were observed and compared. The treatment ended with the sighs of the observation ending, the second progress for the disease or death.Results The overall survival of the experimental group was significantly higher than that of the control group [OS: 58.2(50.7-65.8)/monthsvs. 43.8(30.6-51.6)/months,P=0.040]. The PFS of the experimental group was significantly higher than the control group [PFS: 30.7(23.8-37.7)/monthsvs. 15.2(11.3-19.1)/months,P=0.001]. The KPS of the experimental group was significantly higher than the control group (88.6 ± 10.0vs. 80.5 ± 19.0,t=2.654). The PFS of the triple negative breast cancer (TNBC) in the experimental group was significantly higher than control group [(25.1(12.1-38.0)/monthsvs. 9.9(4.7-15.0)/months,P=0.038].Conclusions The TGBSXJ recipe could extend the OS and PFS and improve the life quality of the patients with advanced breast cancer. In this study, no severe adverse effects had been found in the experimental group.
ABSTRACT
Objective To investigate the epidemic strains of biological type, drug resistance, and the basic clinical characteristics of haemophilus influenzae(Hi)isolated from hospitalized adults with lower respiratory tract infection in Chengdu area.Methods A prospective cross-sectional study was conducted to analyze the biological typing,capsular genes detected by PCR technique,and drug resistance tested by drug sensitive test of Hi epidemic strains isolated from the sputum of adults aged above 18 years who were hospitalized in two tertiary hospitals of west Sichuan in China.Results The positive rate of pathogenic bacteria in adults aged above 18 years who were hospitalized in the two hospitals was 46.71%(15 447/33 069)between November 2013 and October 2014.The positive rate of Hi isolated from the sputum of 100 adults with lower respiratory tract infection was 0.31%(101/33 069).The constituent ratio of Hi in lower respiratory tract infection pathogens was 0.65%(101/15 447).The Hi were all undifferentiated type detected by PCR,and the biological typing of Hi were typeⅠ(42.57%),Ⅳ(29.7%),Ⅱ(15.84%),Ⅲ(9.9%),Ⅶ(1.98%), and Ⅵ(0.9%).The diseases of Hi positive were acute phase of chronic obstructive pulmonary disease(59%), pneumonia(35%), and bronchitis(6%), in which community acquired infection was 55%.The rate of β-lactamase enzyme production was 38.61%.The frequencice of β-lactamase -nonproducing-ampicillin-resistant(BLNAR)strains was 2.97%,and of intermediary strains was 4.95%(5/101).The drug resistance rate of amoxicillin and clavulafiate was 2.97%.The drug resistance rate of cefuroxime was 12.87%, and intermediary rate was 12.87%.The drug resistance rate of cefaclor was 29.7%,and intermediary rate was 8.91%.The drug resistance rate of cefotaxime and ofloxacin was 6.93%and 1.99%.There were no obvious statistical differences between the drug resistance rates of the two hospitals.Conclusions The Hi epidemic strains isolated from the sputum of adults with lower respiratory tract infection were all undifferentiated type,and the common biological types were Ⅰ,Ⅳ,Ⅱ, andⅢ in west Sichuan in China.It should pay attention to the BLNAR strains and ofloxacin-resistant strains.
ABSTRACT
Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) targeted treatment has been a standard therapy for advanced non-small cell lung cancer (NSCLC), but it is not tolerated well by all patients. In China, some studies have reported that traditional Chinese medicinal herbs (TCMHs) may increase efficacy and reduce toxicity when combined with EGFR-TKI, but outside of China few studies of this kind have been attempted.

ABSTRACT
Objective: To prove the clinical therapeutic effect of acute and chronic bronchial asthma with Chuankezhi(CKZ) Injection. Methods: 40 cases of bronchial asthma, including inpatients and outpatients were selected, divided into the attack period group (20) and the relief period group (20). The former was intramuscularly injected CKZ injection 4mL, twice a day, 14 days being a course of treatment. The latter was intramuscularly injected CKZ injection 4mL, twice a day for 15～30 days and 2mL, every other day for 31～90 days; 90 days being a course of treatment. The symptoms and signs, such as asthma, cough, expectroation, pulmonary wheeze were observed. and pulmonary function, absolute eosinophilic granulocyte count and immunogobulin E were measured before and after treatment. Result: By the use of CKZ injection to treat bronchial asthma, the total effective rate amounted to 85% and obvious difference before and after treatment in the two groups ( P
