Helicobacter pylori is a predominant pathogen inducing long-term chronic infection of stomach. Its outer membrane proteins (OMPs) mainly include lipoprotein, fimbriae protein and some adhesions. The adhesions are closely related to the pathogenic processes of adherence, colonization, persistent infection and severe clinical outcomes. In addition, the fact that adherence is vital for colonization and pathogenicity has made it a focus to study the vaccines against adherence. The OMPs related to adherence, their receptors, mechanisms of adherence, and the vaccines are summarized in this review.

OBJECTIVE:To provide reference for the standardization of online pharmacies pharmacist service. METHODS:Lit-erature research method,online entity investigation method and the method of mysterious customer were adopted to investigate 10 well-known online pharmacies,then described the analysis of current online pharmacies pharmacist service in China. RESULTS:There were 5 online pharmacies showing pharmacist service,but only 1 pharmacy could provide pharmacist registration certificate;on average each online pharmacy was allocated with 1.9 licensed pharmacists;only 2 online pharmacies provided 24 hours of phar-macist service;8 online pharmacies provided more than 2 consulting method;messagebox would pop actively when clicking the“Buy”button in 6 online pharmacies;the correct rate of pharmacist’s guidance was less than 60%,only 20% pharmacists could provide right explanation. CONCLUSIONS:The reasons of the lack of online pharmacies pharmacist service include online pharma-cies imperfect laws and regulations and supervision,lack of licensed pharmacists quantity and quality is not high enough,online pharmacies,pharmacists consulting system is not mature. Online pharmacies can improve relevant laws and regulations,strengthen the government supervision,reasonable and effective use of licensed pharmacists resources,perfect the pharmacist online consult-ing service water system and improve the licensed pharmacists to improve pharmacists service function status.

Acquired aplastic anemia is a refractory blood disease for children,and severe acquired aplastic anemia can be a great threaten for life.China is a high incidengce area,children at a period during which this disease can mostly occur.In China,except some congenital aplastic anemia,most children who have this diease is acquired aplastic anemia.In 2009,the Britain society of hematology recommended Guidelines for the diagnosis and management of aplastic anaemia,which represented the latest diagnosis and treatment principle and mainstream view of the clinical methodology about aplastic anemia.They make it clear that the main treatment for the disease are allogeneic hematopoietic stem cell transplantation(allo-HSCT) and immunosuppressive therapy(IST).This article collects the documents in recent 5 years,and provides a overview about the latest advance of the allo-HSCT and IST in the word.

Objective To improve the early diagnosis of Wiskott-Aldrich syndrome (WAS),through summing up and analyzing the clinical characteristics of children with WAS.Methods The clinical and laboratory characteristics of 18 children with WAS,including the cases from Suzhou Jiulong Hospital,Shanghai Jiaotong University School of Medicine,and Tongji Hospital Affiliated to Tongji University,and the domestic reports in recent 6 years,were induced and analyzed.Results All patients were males;the average of incidence age was about 1.9 months and the average age at diagnosis was 10.8 months.All cases had the clinical characteristics of WAS including eczema,infection tendency and thrombocytopenia with small platelet size.Moreover,10/18 cases (55.56％) WAS patients progressed to severe cases (scores reached to 4 or 5 points)at diagnosis,and with the increase of age of the patients at diagnosis,the ratio of severe cases would be increased.The conventional immune function indexes showed no specific diagnostic value,and the typical clinical features and the WAS gene mutation detection were the key diagnostic basis.Seven cases used to be misdiagnosed as idiopathic thrombocytopenia,and received corticosteroids and intravenous immunoglobulin therapy.In a total of 18 cases,4 cases received allogeneic hematopoietic stem cell transplantation,of which,β cases were cured and 1 case died of transplantation-related interstitial pneumonia,while the remaining 14 cases are unknown for their with follow-up treatment and prognosis.Conclusions The typical clinical features and the WAS gene mutation detection were the key diagnostic basis.In order to improve the rate of early diagnosis and avoid misdiagnosis,it's a great need to improve the clinical understanding of WAS.

Objective To investigate the expression of matrix metalloproteinases and tissue inhibitor of metalloproteinases in active Mooren's ulcer corneas.Methods An indirect immunofluorescent technique was used to visualize the presence of matrix metalloproteinase-1,2,3,9 and tissue inhibitor of metalloproteinase-1,2 in active Mooren's ulcer corneas from 6 patients and normal human corneas from 4 corpses.The results were further analyzed by an image-processing system.Results Only TIMP1,2 were detected in normal corneal epithelium while MMP-1,2,3,9,and TIMP-1,2 all were found in Mooren's ulcer corneas.MMP-2,TIMP-2 expressed in epithelium,MMP-3 expressed in stroma,MMP-1,9,and TIMP-1 expressed in both epithelium and stroma.Conclusion In active Mooren's ulcer cases,corneal lesion and corneal wound healing coexist,but the destructive reaction is greater than wound healing.Over-expression of MMP-9 and unbalanced regulation of MMPs/TIMPs may play an important role in the Mooren's ulcer of this stage.

Objective To investigate clinically applied value of P300 with influential factors in olivopontocerebellar atrophy (OPCA). Methods The P300 and cognitive ability sifting investigation (CASI) were tested in 34 OPCA cases and normal controls with equal age, gender and educational levels. Results The P300 latency was significantly longer in OPCA group of different ages than that in the normal control group (P

An extract(Polysaccharide)from Zhu-Ling(Polyporus umbellatus)and hydro- cortisone acetate were injected into mice for seven days in the experiment.Peritoneal macrophages were taken out for cytochemical analysis.The results were quantified with MPV-2 microspectro-photometer.It was found that the activity of AePase, ATPase and ANAE and the content of polysaccharide were reduced after injection with hydrocortisone acetate;that the activity of AcPase,ATPase and ANAE and the content of polysaccharide were enhanced after injection with the extract from Zhu-Ling;and that the hydrocortisone acetate and the extract from Zhu-Ling were injected into mice at the same time,the activity of enzymes and the content of polysaccharide were similar to the control group.

Objective To study the sample quality of 'whitish' Radix Salvia Miltiorrhiza(the root of a grown-environmental-influenced variant sample of Salvia miltiorrhiza,which cortex and transection is white) grown in Luanchuan Region of Henan Province and normal Radix Salvia Miltiorrhiza by the means of TLC and HPLC chromatographic fingerprints;hence to compare the difference of their constituents.Methods TLC Chromatographic condition: Precoated silica gel F_(254) plate;hydrophilic and lipophilic constituents were developed and derivatizated with different solvent systems and visualization reagents,respectively.HPLC Chromatographic condition: Zorbax SB C_(18) column;hydrophilic and lipophilic constituents were gradient eluted,respectively.Results The 'whitish' Radix Salvia Miltiorrhiza contains lower content of lipophilic compounds,the main diterpene quinones was only trace amount,while the content of hydrophilic constituents was relatively higher.Conclusion The 'whitish' phenomenon suggests that the 'micro'-environmental condition can probably influence negatively the bio-synthesis of diterpene-quinones.The factors of influence still need further study.Such phenomenon would be worth concerning seriously for GAP administration.

OBJECTIVE To strengthen the infection management in the public and private town hospitals.METHODS We investigated the infection management in the public and private hospitals which are below Grade 2 in our city.RESULTS The problems existing in the infection management in these hostpitals were obvious and severe,mainly including the leaders′ ignorance of the importance of infection management,incomplete organization and regulation,medical workers′ lacking of the related knowledge about infection management,behindhand hospital infection management, monitoring and prevention,and incorrect sterilization.CONCLUSIONS The infection mangement in public and private town hospitals is weak and needed to be strengthened.
