Objective:To analyze the cause of the blood heat syndrome in psoriasis.Methods: Made the investigation form about information of psoriatic patients through DME method and reference both Chinese and foreign documents,analyzed main component of data by SAS software.Results: The first main component of blood heat syndrome in psoriasis are infection,drinking,dietetic problem,and emotion;the second main component is family history;the third main component is dampness;the forth main component is the allergy to the food;the fifth is outside irritation.Through the corresponding investigation we found that food include hot food,beef,sheep and sea food,emotion problem include over work and stress,dampness include work and living in humid place for long time,outside stimulus meant chemical stimulus.Conclusion: The main cause of the blood heat syndrome in psoriasis are infection,drinking,dietetic problem,and emotion,family history,humidity,allergy to the food and chemical stimulus in order.

OBJECTIVETo study the overexpression of Sox9 gene on rabbit bone marrow mesenchymal stem cells for repairing articular cartilage injury in vivo.

METHODSRabbit bone marrow mesenchymal stem cells (BMSCs) were transduced with lentivirus vector containing Sox9 gene and then cartilage specific molecule was detected by RT-PCR in vitro. Total 48 knee joints of 24 mature New Zealand white rabbits were randomly divided into 3 groups according to different defect treatment. After animals anesthesia,a full-thickness cylindrical cartilage defect of 4 mm diameter and 3 mm deep was created in the patellar groove using a stainlesssteel punch. Meanwhile, the transfected cells were implanted to repair the rabbit model with full-thickness cartilage defects. Cartilage defects tissue was observed with light microscope, electron microscope, HE and immunohistochemistry staining to assess the repair of defects by the complex at 6 weeks or 12 weeks after the implantation.

RESULTSAt 3 days after the transfection, Sox9 gene expression was highest and Sox9 gene expression decreased with the increase of time. At 3 days after the transfection, the expression of collagen type II began and reached the peak at 14 days. It showed that the bone marrow mesenchymal stem cells went into chondrogenic differentiation after transfected by Sox9 gene. Histological observation showed that at 6 weeks after the operation, the defects in the experimental group was filled with hyaline like cartilage tissue, 12 weeks after operation,the defects of cartilage and subchondral bone had satisfactory healing. Both at 6 and 12 weeks postoperatively, the defects were filled with fibrous tissues in control groups. Meanwhile, immunohistochemical staining of sections with type II collagen antibodies showed the proteins in the regenerated tissue stained positive for type II collagen and stronger than the control groups. The histological scoring system indicated that the cartilage repair of experiment groups were better than the two control groups with statistical significances.

CONCLUSIONOverexpression of Sox9 gene on rabbit bone marrow mesenchymal stem cells (BMSCs) promote the repair of cartilage defect.

Objective To review the clinical features , diagnosis , prognosis and treatment of polycythemia vera ( PV) complicated with acute coronary syndrome ( ACS) .Methods The clinical data of 2 PV patients complicated with ACS admitted to Peking Union Medical College Hospital ( PUMCH ) were retrospectively analyzed and the recent literatures were reviewed .Results Case 1 was a 65-year old man who had been diagnosed PV with a positive JAK2V617F mutation 3 years ago.At presentation, the patient was suffering from recurrent angina pectoris , and coronary angiography revealed that there was a severe ( 80%) stenosis in the middle segment of left circumflex and a Xience V stent was implanted .After the percutaneous transluminal coronary intervention ( PCI ) , secondary prevention for coronary heart disease and hydroxyurea for PV were given and the patient has been followed up regularly for more than three years and he is going well.Case 2 is a 44-year old man who was diagnosed PV with a positive JAK 2 mutation 3 years ago and hydroxyurea, interferon, aspirin was prescribed.Then splenic infarction, thrombosis of splenic vein,regional portal hypertension , severe varices of fundus of stomach and upper gastrointestinal bleeding developed with him.Two months ago , an AMI of inferior wall occurred and the angiographic findings demonstrated an thrombotic lesion in the proximal segment of the right coronary artery with a moderate stenosis ( 60%);1 month ago an AMI of anterior wall developed and coronary angiography discovered that there were diffuse thrombus in the proximal segment of left anterior descending artery with a severe stenosis ( 90%) and a complete occlusion in the right coronary artery .After double antiplatelet therapy with anticoagulation therapy of warfarin was given , the patient recovered gradually .Conclusions PV complicated with ACS is relatively rare.According to recent studies, positive JAK2V617F mutation, leukocytosis, age >65 years and positive history of thrombosis are the most important predictors of cardiovascular events .Clinicians should design individualized treatment strategies for patients on the basis of clinical features , coronary angiography findings and complications .For those with thrombotic lesion in the coronary artery due to the hypercoagulative state caused by PV, it should be cautious to carry out a coronary revascularization treatment .

Conjugal plasmid pGH112 has been developed based on the replicons of Streptomyces coelicolor plasmid SCP2 and E. coli ColE. The plasmid contains ampicilin resistance gene(amp) for selection in E. coli and thiostrepton resistance gene (tsr) for selection in Streptomycetes, and a 0.76 kb oriT fragment of (IncP) RK2. Conjugal transfer of pGH112 was performed from E. coli to S. coelicolor A3(2), S. avermitilis, S. lividans TK54, S. toxytricini NNRL15443, S. venezuelae ISP5230 and Sacc. erythraea by conjugation, results show that the plasmid was able to transfer efficenctly from E. coli to Streptomycetes, was stably inherited in the recipients. pGH113 was constructed from pGH112 by combining the constitutive ermE promoter with green fluorescent protein gene(gfp).

OBJECTIVETo evaluate the effects and safety of Shuangfujin (SFJ) on acute eczema.

METHODSOne hundred and twenty patients with acute eczema were randomly assigned to 4 groups equally, the saline group, the boric acid group, the Pifukang lotion group and the SFJ group, treated with respective medicine.

RESULTSAfter 4 days of treatment, the symptom score was remarkably lower in the SFJ group than in the other three groups (P<0.01), score in the saline group was higher than that in the boric acid group and the Pifukang lotion group, and insignificant difference was shown between the latter two groups. The total effective rate and cured rate were 46.4% and 14.3% in the SFJ group, which were matched to those in the Pifukang lotion group and significantly higher than those in the other two groups (P <0.01), and the saline group showed the lowest efficacy. The effect of stopping itch in the SFJ and the boric acid group were matched, which was higher than that in the Pifukang lotion group, and the lowest was in the saline group. No skin irritant reaction and other adverse reactions were found.

CONCLUSIONSFJ is effective, safe and convenient in treating acute eczema.

An about 700 bp DNA fragment was amplified from genome DNA of S. aureus TSTw by PCR. This fragment was cloned into pGEM-7Zf(+) and the recombinant plasmid was transformed into E. coli DH5 alpha. The sequencing result of the recombinant plasmid demonstrated that it contains seb gene with 717 bp (without signal encoding region of 81 bp) which has the same nucleotide sequence as described in literature. The seb gene was cloned into expression vector 7ZTS and was transformed into E. coli JM109 (DE3). The expression level of SEB was as high as 33.3% of the cell total proteins.

The rare codons of a fragment in staphylococcal enterotoxin A gene were turned into the most high usage frequency codons in E. coli by overlap PCR technique. Genes of sea and seam were cloned into 7ZTS expression vector and transformed into JM109(DE3), respectively. The result shows that expression level of sea gene was very low, but the expression level of seam was as high as 15% of total cell proteins. The expression product shows activity of antitumor in vivo.
