The paper is to report the establishment of a method for quickly evaluating compatibility of Chinese medicines injections. Isothermal titration calorimetry (ITC) was used to evaluate compatibility of Yiqifumai (YQFM) and vitamin C injection (Vc)/5% glucose injection (5% GS). The diversification of Gibbs free energy (deltaG), enthalpy (deltaH) and entropy (deltaS) were used to decide reaction types of colliquefaction procedures of different injections. The reactive profiles were used to determine signs and quantity of heat. And high performance liquid chromatography (HPLC) was used as a supportive method for ITC. Then, feasible binding sites were analyzed based on the information of spatial structures of major compositions. During the colliquefaction procedure of YQFM and Vc, [deltaH] > T[deltaS], so, the reaction is enthalpy-driving. And the reactive profile showed that a big deal of heat was given out during the procedure. Obviously, chemical reactions happened and the major compositions changed. On the other side, the reaction of YQFM mixed with 5% GS was entropy-driving, because [deltaH] < T[deltaS]. The reactive profile showed there was a little heat gave out. So, non-chemical reactions happened, and the major compositions did not change. The conformity existed between the results of ITC and HPLC. ITC could be used to evaluate the compatibility of Chinese medicines injections because of the advantages of ITC, such as real time, fast, sensitive and having more parameters.

Objective To analyze the drug resistance gene carrying situation of carbapenem-resistant Klebsiella pneumoniae (CRKP) and molecular epidemiological characteristics to provide a reference basis for studying the bacterial drug resistance.Methods A total of 37 clinically isolated strains of CRKP were collect ed from February 2016 to February 2017.The broth microdilution method was used to determine the strain drug susceptibility.The phenotypes of CRKP carbapenemases were detected by using the modified Hodge test and EDTA-imipenem synergistic method.The drug resistance genes of KPC-2,NDM-1 and OXA-48 were detected by PCR.The sequencing and internet comparison were performed for determining the genotype.The multilocus sequence typing (MLST) was adopted to conduct the genetic correlation study on the strains.The evolutionary trees were constructed by using the MEGA software and the genetic relationship was analyzed by using the eBURST software.Results The drug resistance to commonly used antibacterial drugs was over 90％.The KPC-2 gene was detected in all strains,3 strains simultaneously carried the NDM-1 gene,and other genes were negative.In MLST typing,25 strains were ST11,each 2 strains were ST524 and ST789,each 1 strain was ST35,ST29,ST1066 and ST244 respectively.Also a new ST type(2 strians) was confirmed by the PubMlst database and named as ST1792.The ST11 type group and non-ST11 type group had no statistical difference in the aspects of the age,sex,infection route and antibiotics use(P＜0.05).Conclusion Carrying KPC-2 gene is the main cause leading to bacterial resistance to carbapenem and ST11 type is the most popular clone type.

Objective To study the expression of Snail in laryngeal carcinoma and to explore its relationship with invasion and metastasis in subgroup laryngeal carcinoma cells. Method The expression of Snail protein was examined by immunohistochemistry staining in the tissue of laryngeal carcinoma. The statistical evaluation was performed to detect the correlation between the Snail protein expression and clinical features. In different subgroups of laryngeal carcinoma cells (CD 44+CD 133+cells, CD 44 and CD 133-cells), the expression of Snail and adhesion molecules E-cadherin were detected by RT-PCR,Western blot test and immunochemical staining which were studied in the correlation with invasion and metastasis. Results The result of immunohistochemical staining revealed that Snail was moderately or highly expressed in the tissue of laryngeal carcinoma significantly and higher than those in adjacent non-cancerous tissues(P<0.01). Expression of Snail was highly correlated with lymph node metastasis, tumor differentiation and clinical classification(P<0.05).However, it was not related to the age , gender and clinical type. RT-PCR and Western blot test results confirmed that the expression level of Snail was significantly higher in CD 44+CD 133+laryngeal cancer cells than in CD 44-and CD 133-laryngeal cancer cells, otherwise the expression level of E-cadherin in CD 44+CD 133+laryngeal cancer cells was significantly lower than in the CD 44-and CD 133-laryngeal cancer cells. Cell immunohistochemical staining confirmed the expression of Snail and E-cadherin were negatively correlated in CD 44+CD 133+laryngeal cancer cells. Conclusion Over expression of Snail in laryngeal carcinoma is closely related to the development of laryngeal cancer and lymph node metastasis. The expression of Snail in the CD 44+CD 133+laryngeal cancer cell subgroup is negatively correlated with adhesion molecules E-cadherin, which is a close correlation with invasion and metastasis of laryngeal cancer cells.

OBJECTIVETo observe the effect of Yiqi Huoxue Qingre Huashi Recipe (YHQHR, a recipe capable of supplementing qi, activating blood, clearing heat, and dissipating dampness) on ulcer healing and Helicobacter pylori (Hp) eradication rate in Hp positive peptic ulcer patients, and to explore coccoid Hp occurrence in the eradication.

METHODSTotally 80 Hp positive peptic ulcer patients were assigned to the treatment group and the control groups by random digit table, 40 in each group. All patients received standard triple therapy of Western medicine for 2 successive weeks. Those in the control group additionally took omeprazole enteric coated tablet, 20 mg each time, once per day for 4 successive weeks. Those in the treatment group additionally took YHQHR, twice per day for 6 successive weeks. The ulcer healing was observed and recorded by gastroscope after discontinued medication of 14 days. The effective rate of ulcer healing under endoscope was statistically calculated. Rapid urease test (RUT) was performed in one small piece of tissue from corpora ventriculi and sinuses ventriculi using 14C breathe test (UBT). Gastric juice was collected from the stomach. Hp urease gene amplification test (urea A-PCR) was performed in living tissue from gastric antrum. Results obtained from the above three test methods were recorded and assessed to decide the final eradiation rate. Gastric mucosa tissue was observed under electron microscope,attempting to find non-eradicated Hp, which was further observed.

RESULTSThe total curative effect under gastroscope was 97.5% (39/40 cases) in the treatment group, obviously higher than that in the control group (80.0%, 32/40 cases) (P < 0.05). The eradication rate of Hp was 75.0% (30/40 cases), obviously better than that of the control group (52.5%, 21/40 cases) (P < 0.05). The total positive Hp numbers after treatment was 14C UBT (12), RUT (8), and urea A-PCR (27), respectively. The Hp positive rate detected by 14C UBT and RUT was lower than the Hp positive rate detected by urea A-PCR (P < 0.05). Rod-like and coccoid Hp bacteria could be observed under electron microscope.

CONCLUSIONYHQHR combined standard triple therapy was more effective than standard triple therapy alone in promoting ulcer healing and elevating the eradication rate of Hp.
