The‘prevention and early treatment of diseases’conception as‘Huangdi Neijing’suggested,is the highest academic realm among the Chinese medical theory,it flows through the entire process of Chinese medical theory and diseases prevention.Four aspects of the prevention conception manifested in the process of Chinese medical prevention of diseases are: Taking preventive measures before confirmed diagnosis(health cultivation),impeding diffusion after confirmed diagnosis, deterring diffusion from deterioration,and restraining deterioration from being malignant.The malignant causal chain conversion of the coexistence of asthenia and sthenia is considered as the inducing links of critical illness’occurrence,evolution and transformation.Therefore,to intercept the malignant causal chain conversion comes to the key technique of Chinese medical remedy for critical illness.The‘prevention and early treatment of diseases’conception must impenetrate the versal process of treating critical illness.The overall clue and method of Chinese medical remedy for critical illness is to identify and grasp the vital contradiction and each respect of the malignant causal chain conversion which concurs with the evolution of the critical illness,simultaneously utilize the method which combined the prevention in etiology and pathogenesis with the remedy in etiology and pathogenesis,then actuate the pathologically changed organism to extricate from critical conditions at the first opportunity, finalizing with convalescence and recuperation thereafter.

Objective To compare the efficacy in radical cure of H.Pylori (Hp) by different proton pump inhibitor (PPI)-based treatment regimens.Methods One thousand two hundred and three H.Pyloriinfected patients diagnosed by both endoscopic pathology and a rapid urease test were enrolled in this study.Reviewed 13 C-urea breath test at the end of Hp eradication treatment for more than 4 weeks,and retrospective analyzed the different effect of Hp eradication regimens.All patients were given treatment regimens,which including PPI (esomeprazole azole,bella,esomeprazole,pantoprazole omeprazole,2 times/d) plus antimicrobial for 7,10,14 d.According to antimicrobial,patients were divided into A,B,C,D,E group.Patientss in group A(421 cases) were given amoxicillin 1.0 g,2 times/d,clarithromycin 0.5 g,2 times/d;In group B (49cases) were given amoxicillin 1.0 g,2 times/d,levofloxacin 0.2 g,2 times/d;In group C(69 cases) were given amoxicillin 1.0 g,2 times/d,metronidazole 0.4 g,2 times/d;In group D(559 cases) were given clarithromycin 0.5 g/d,2 times/d,levofloxacin 0.2 g,2 times/d and in group E(105 cases) were clarithromycin 0.5 g,2times/d,metronidazole 0.4 g,2 times/d.Bismuth were colloidal bismuth pectin 200 mg,2 times/d.Results The radical cure rate of Hp was 84.04％ (453/539) in the group treated by regimens with Amoxicillin,and significant higher than that of without Amoxicillin (69.12％ (459/664),x2 =36.104,P =0.000),and the radical cure rate of Hp was 14.92％.The Hp radical cure rate of quadruple therapy was 76.85％ (767/998),while triple therapy was 70.73％ (145/205).However,no significant difference between these two regimens was found(x2 =3.476,P =0.062).The Hp radical cure rates of 14-,10-and 7-day course therapies were 84.28％ (134/159),75.79％ (579/764),71.07％ (199/280) respectively,and there was significant different among the three groups (x2 =9.644,P =0.008).There was significant increases trend in the 14-day therapy group comparing to 10-and 7-day regimen groups (x2 =5.399,11.719,P =0.020,0.001 respectively),while no significant difference was shown between the 10-and 7-day therapy groups(x2 =2.398,P =0.121).The radical cure rates were 84.80％ (357/421),81.63％ (40/49),81.16％ (56/69),69.95％ (391/559),64.76％(68/105) respectively in A,B,C,D and E groups,and there was significant difference among the groups (x2 =37.999,P =0.000).Conclusion Radical cure therapy of Hp should be PPI-based.A 14-day triple or quadruple treatment regimen with combination of Amoxicillin and clarithromycin is suggested as a first-line therapy.It is worth to clinically popularize such regimens in the light of the superior efficacy.

Objective To investigate neurological recovery effect and mechanisms of blood activating and phlegm removing decoction in the treatment of patients with hypertensive cerebral hemorrhage.Methods 68 patients with hypertensive cerebral hemorrhage in our hospital were divided into two groups.34 patients of the control group were given conventional western medicine,and 34 patients of the observation group were taken conventional western medicine combined with blood activating and phlegm removing decoction.The clinical outcomes, hematoma volume change and neurological recovery were compared,and analyzed its mechanism of action.Results The effective rate of the observation group(94.12%) was significantly higher than 73.53%of the control group (χ2 =5.31,P<0.05). After 7d,14d,21d treatment,NIHSS scores of the observation group [(12.87 ±1.43) points,(8.55 ±1.11) points and (5.67 ±0.76) points] were significantly lower than those of the control group [(20.43 ±2.57) points, (17.66 ±2.08)points,(14.54 ±1.44)points],and the differences were statistically significant (t=14.99,22.53, 31.76,all P<0.05).After treatment,hematoma volume of the observation group[(6.44 ±0.54)mL]was significant-ly lower than before treatment[(16.30 ±1.90)mL]and after treatment in the control group [(12.11 ±1.44)mL] (t=29.11,21.50,all P<0.05).After treatment,ALD score of the observation group [(66.34 ±5.22)points] was significantly lower than before treatment[(27.53 ±2.20)points]and after treatment in the control group[(47.55 ± 3.33)points],and the differences were statistically significant(t=39.95,17.70,all P<0.05).Conclusion The effect of blood activating and phlegm removing decoction in the treatment of patients with hypertensive cerebral hemor-rhage is significant,can significantly improve neurologic impairment and daily living skills,has no obvious conflict of interest and high application value,worthy of promotion and application.

Human leukocyte antigen G ( HLA-G) is a member of the non-classical HLA classⅠb family. It is considered to play a crucial role in immune tolerance. A unique feature of HLA-G is the struc-tural diversity as surface expressed and as secreted molecules, which is mainly attributed to alternative spli-cing of the primary transcript. HLA-G can promote the invasion and metastasis of tumor cells through various ways. In addition, HLA-G has been described included in exosomes. Exosomes released by most cell types are nano-sized vesicular bodies that contain lipid bilayer and rich contents. As a new marker for diseases, exosomes are extensively involved in the occurrence and development of diseases. Recent studies have found that exosomes can express soluble HLA-G, which reveal a new way by which HLA-G regulates tumor micro-environment. In this review, we focus on the expression of HLA-G on exosomes to provide new thoughts for the early detection and treatment of tumors.

Objective:To explore the immune response in mice fed orally with the conjugated antigen of HpaA-CtxB(HCTB).Methods:A recombinant strain which could express bivalent antigen of HpaA and CtxB subunit was constructed. HpaA and CtxB gene was amplified by PCR. The DNA products of HpaA and CtxB were inserted into a prokaryotic expression vector pQE-30 respectively, and then translated into E.coli strain DH5? to express HCTB fusion protein. Its immunogenicity was analyzed by Western blot. After purification, to fed mice by oral immunization. The change of antigen-specific ASC antibody(IgG and IgA) in the mucosa of the animals were detected by ELISPOT and ELISA assay. Results:HCTB fusion gene was sequenced as 1 161 bp, the fusion protein encoded polypeptides of 387 amino acid residues.The molecular weight was 40 kD analysed by SDS-PAGE. The level of soluble expression product was about 41.67% of total cell protein. After affinity chromatography, the purity of fusion protein was above 92%.Western blot analysis confirmed that fusion protein could be specifically recognized by the serum of anti-HpaA and anti-CT. Antigen-specific ASC and antibody response in animals immunized with HCTB or HpaA was determined by ELISPOT and ELISA. The results showed that the number of sIgA and IgG-ASC increased significantly in PP and gastric mucosa, especially those of the sIgA-ASC by orally immunization with HCTB. The levels of specific antibody were also higher than those of controls. Conclusion:The results indicated that the oral immunization with HCTB induces effective mucosal immune respones and produced higher levels sIgA. The recombinant fusion protein HCTB can be used as an effective oral vaccine for prevention and treatment of infection of Hp.
