Psoriasis is a recrudescent chronic inflammatory dermatosis which is called“tinea”in ancient times. Its pathogenesis is not only associated with changes in the blood and body fluids, but also has close connection with external infection of six evil factors. This article sorted data of pathogenesis and treatment from the perspective of external infection of six evil factors, and discovered that pathogenesis of psoriasis includes external factors of four evils of wind, cold, damp and heat and internal factors of blood deficiency and blood dryness. Ancient treatment was based on dispelling wind, clearing away heat and moistening dryness. The pathogenesis can be summarized as follows:wind and poison attack skin and hinder blood production. The treatment can be “let in air for detoxification, enrich blood and moister dryness, cooling and activating blood”, blood and functional status of organs of patients should be observed, with a purpose to provide references and basis for modern clinical prevention and treatment of psoriasis.

Urticaria, which is called as“yin zhen”in traditional Chinese medicine, is a kind of allergic skin disease with comings and goings of wind clumps patches. Its episodes have close relationship with external infection of six evil factors. This article collected, classified, and studied literature of TCM doctors in different dynasties about urticaria and external infection of six evil factors, and expounded pathogenesis of urticaria in the aspects of wind pathogen, dampness pathogen, fire evil and other pathogenic factors. In the treatment of urticaria, internal treatment is divided into dispelling wind method, eliminating dampness method, clearing heat method and other methods. External treatment is concluded form the aspects of washout method, medicated ironing method, and moxibustion method. This article classified and dig some valuable information, with a purpose to provide reference and evidence for prevention and treatment of urticaria.

Influenza,caused by influenza virus,is a respiratory infectious disease with a serious hazard to human health.Prevention of influenza through vaccine development is the most effective strategy.It is important to build a rapid response platform for research and production of influenza vaccine.As virus vectors,live vaccine provides a new prevention and treatment way for infectious disease.Modified vaccinia virus Ankara(MVA) is a replication-deficient viral vector that is safe and can encode one or more foreign antigens and induce humoral and cellular immune response.MVA holds great promise as a vaccine platform.In this review,we discuss the use of MVA for vaccine development against influenza virus.

Objective To study the bacteriostatic activity and stability of pine bark Oligomeric Proantho Cyanidins. Methods By the K-B disk diffusion method, spoilage bacteria as experiment strains, to study the inhibition effects of the pine bark Oligomeric Proantho Cyanidins and the antimicrobial stability under certain temperature, pH, and UV exposure time. Results Pine bark Oligomeric Proantho Cyanidins had significant inhibitory effect on Gram positive bacteria (Staphylococcus aureus and Bacillus Sukatilis), which had better inhibition effects in the media neutral, but temperature and UV had little influence on the antimicrobial effects. The minimum inhibitory concentration (MIC) of pine bark Oligomeric Proantho Cyanidins against Staphylococcus aureus and Bacillus Sukatilis were 12.5 and 6.25 mg/mL, respective. However, on Gram negative bacteria(Escherichia coli and Pseudomonas aeruginosa) there was no obvious inhibition effects. Conclusion The pine bark Oligomeric Proantho Cyanidins has significant inhibitory effect on Gram positive bacteria, the inhibitory effect is stronger in the range of pH 6-7 , and the temperature and UV had a little effect on its antibacterial action, which means that the antibacterial action of pine bark Oligomeric Proantho Cyanidins had good stability.

Objective To understand the clinical characteristics of systemic lupus erythematosus with Antiphospholipid syndrome (SLE-APS).Methods The clinical data of 39 cases of SLE-APS were collected and analyzed retrospectively. Results Thirty-one patients had 48 thrombosis episodes in total, among which the most common presenting manifestations were deep venous thrombosis and stroke. 12 of 26 married women had fetal morbidity. The prevalence of anticardio lipin antibody (aCL) and lupus anticoagulant ( LA) was 72% and 41% , respectively. 24 patients had SLE at first,on an average of 9. 5 years later they had the characteristics of APS, 12 patients had thrombosis episodes or fetal morbidities ,4. 8 years later they developed into SLE,and 3 patients had the characteristics of SLE and APS from the onset The SLEDAI was less than 5 in five cases when they had thrombosis episodes or fetal morbidities.Conclusions The incidence of thrombosis episodes or fetal morbidities increased in SLE-APS patients. APS occurred before, after or at the same time with SLE. SLE patients might have the clinical features of APS during the steady stage. It's very important to ask the medical history in detail and measure aCL in lupus patients to find the risk factor of APS and prevent the APS' occurrence.

Objective To observe the effect of bronchial asthma in rats treated by Chuanzhuping,a prescription which has the function of dispersing lung Qi and invigorating spleen Qi,and explore its possible mechanism.Method Thirty-two male Wistar rats of SPF level were divided into four groups randomly:control group(A),asthma group(B),Dexamethasone group(C) and Xiaozhuping group(D).Except group A,the others were established animal model of asthma.After drawing materials,hematoxylin and eosin(HE) staining were performed.The pathological changes in bronchopulmonary tissue of rats were detected.The basementmembrane perimeter(Pbm),the airwaywall area(Wat) and the smooth musclewall area(Wam) were measured and calculated by using image analysis system.The concentration of transforming growth factor-?1(TGF-?1) in bronchopulmonary tissue was observed by immunohistochemical method and the integral optical density(IOD values) of it was measured.Results In bronchopulmonary tissue of group B,Wat,Wam and the concentration of TGF-?1 increased,and were significantly different from that in group A(P0.05).In group D,the concentration of TGF-?1 decreased and was significantly different from that in group C(P

OBJECTIVE To investigate the drug susceptibility of clinical isolates in local region for using antibiotic reasonably. METHODS Totally 3 170 strains of clinical isolates were identified by API and Microscan and tested for drug resistance against antimicrobial agents by K-B method. WHONET5.4 was applied for analysis. RESULTS The commonly encountered bacteria were Pseudomonas aeruginosa (24.3%), Acinetobacter baumannii (10.9%), Klebsiella pneumoniae (10.4%), Escherichia coli (8.9%), and Staphylococcus aureus (SA,8.0%). In Gram-negative isolates, the resistance rate to meropenem was 19.7%, and to piperacillin-tazobactam was 26.5%. The incidences of E.coli and K. pneumoniae isolates producing extended spectrum beta-lactamases (ESBLs) were 49.1% and 33.5%, respectively. In Gram-positive isolates, the susceptibility rate to vancomycin and teicoplanin both was 100.0%. The oxacillin resistant rates of SA and coagulase negative Staphylococcus (CNS) were 54.2.0% and 82.3%. CONCLUSIONS The production ratio of ESBLs and oxacillin resistance of bacteria in local region are high. It is important to promote the rational use of antimicrobial agents and take effective contaminant methods to reduce resistant rates of bacteria and dissemination of multi-resistant bacteria.

Diabetes is a common clinical disease, with glucose and lipid metabolism disorder as the main clinical manifestation. The spleen of middle jiao can transport and transform the essence of grain and water. It is also the source of qi and blood, which also provides material foundation for the glucose and lipid metabolism. The spleen deficiency and dampness stasis can lead to the phlegm and blood stagnation, which are closely related to high sugar, high fat, high blood coagulation and vascular endothelial damage. This article discussed the relationship between the changes of spleen function of middle jiao and glucose and lipid metabolism, and provided some theoretical methods for clinical prevention and treatment of diabetes.

Objective To study the roles of apoptosis and expression of the related genes in minor labial salivary gland of patients with primary Sjogren′s syndrome (pSS). Methods Biopsies of minor submucosal labial salivary gland (SG) were obtained from 30 patients with pSS and 10 control individuals. The in situ end labeling and immunohistochemical staining were used to detect the apoptotic cells and the expression of Fas, FasL and Bcl-2. Results The percentage of apoptotic acinar and ductal epithelial cells (AEC and DEC) in labial salivary glands of patients with pSS was significantly higher than that of control respectively, but the percentage of apoptotic infiltrating mononuclear cells (IMC) showed no significant difference compared with that of control, pSS AEC and DEC showed increased expression of Fas/FasL and decreased expression of Bcl-2, whereas pSS IMC showed increased expression of Fas, Fas/FasL and Bcl-2. There was significant positive correlation between the percentage of apoptotic cells and the cells expressing Fas and FasL in pSS AEC DEC and IMC, respectively, and there was significant negative correlation between the percentage of the apoptotic cells and that of cells expressing Bcl-2 in pSS DEC and IMC, but there wasn′t correlation between the percentage of the apoptotic cells and that of cells expressing Bcl-2 in pSS AEC. Conclusions The apoptotic cells increased in the epithelial cells and decreased in IMC of the labial salivary glands may be one of the mechanisms leading to the glandular destruction found in pSS. In pSS labial salivary glands, the expression of Fas and FasL may promote apoptosis, while the expression of Bcl-2 may inhibit apoptosis. The increased expression of Bcl-2 in pSS IMC indicates that IMC may be able to escape apoptosis, resulting in inflammatory cell foci.

The microvasculature of the submandibular glands of guinea pig's was studied with the replica-SEM msthod. Special attention was paid to the microvascular architecture around the glandular ductal tree, which is mainly dichotomous, but usually asymmetrical and irregular, with a divergent angle of 40-80? and 7-8 grades of branching. The ductal tree is surrounded with a periductal vascular plexus. The periductal plexus of the excretory ducts can be divided into two layers: the inner layer is formed by capillaries and the outer layer by veins, so called venous coat. This venous coat is complexly constructed with button veins, loop veins and complicated venous circulatory by-passes. The capillary plexus of the striated ducts and intercalated ducts is supplied by venules with the cha-ractristics of the portal vein as they come from the capillaries of the acini. There are complex A-V and V-V anastomoses at the venous coat and at the lobu-lar porta.The significance of the microstructures described above was discussed.
