1.Application of p53 gene therapy for malignant lymphoma
Journal of International Oncology 2008;35(7):547-549
In majority of malignant lymphoma patients the overexpression of mutant p53 gene can be found,and experiments show that p53 gene and the genesis currence and development of malignant lymphoma are closely related.Thus,normal p53 gene carried by recombinant adenovirus vector into tumor cells and its stable expression will play a theraputic role in the treatment of malignant lymphoma.This has been confirmed by the basic research.

Major depression disorder is an increasing heavy burden in modem society, but its pathological mechanism is still vague. Recent evidence indicated that two pore potassium channel, TREK1, is one of the important drug targets of antidepressants. The structural and functional research progress of TREK1 potassium channel were reviewed with an emphasis on its roles in anti-depression, neuronal protection, and neuronal plasticity. The complicated interactions between TREK1 potassium channel and monoamine transmitters-receptors were also reviewed and future directions to explore the underline mechanism were also discussed.

Objective To assess the level of soluble Fas (sFas) and soluble Fas ligand (sFasL) in the sera of patients with systemic lupus erythematosus (SLE),rheumatoid arthritis (RA),multiple sclerosis (MS)and insulin dependent diabetes mellitus (IDDM).Method The level of sFas and sFasL was determined by a sandwich enzyme linked immunosorbent assay.Anti ssDNA (single stranded DNA) was detected by indirect enzyme linked immunosorbent assay.Results The level of sFas in patients with SLE,RA,IDDM and MS was significantly higher than that in healthy individuals.It was interesting that among these autoimmune diseases,the level of sFas in the sera of patients with SLE was dramatically higher than that of the other diseases.The high level of sFasL accompanied by sFas was found in the sera of SLE and RA patients.In the sera of patients with SLE,the anti ssDNA antibody always accompanied by high concentration of sFas and,by contrast,no anti ssDNA antibody was found in all the patients in whose sera no sFas was found.In patients with IDDM,the sFasL level of the serum was significantly lower than that of the serum of healthy donors.Conclusion Serum sFas level of patients with SLE,RA,MS and IDDM is higher than that of healthy individuals.These results indicate that the sFas level can be used as a marker of disease progress and relaxing after treatment with the medicine.It is also demonstrated that there is relationship between the level of anti ssDNA antibody and sFas.The level and significance of serum sFas and sFasL in these autoimmune disease patients are under investigation.

Keratoconus is a progressive and bilateral corneal disease with the characteristics of the protrusion of the dilated and central thinning cornea.Keratoconus often causes myopia and irregular astigmatism, and corneal edema and scarring in the late stage, leads to significant vision loss, and brings patients psychological pressure and economic burden.Eye rubbing is an important risk factor of keratoconus.Many studies suggest that eye rubbing is related to the occurrence and development of keratoconus.Different frequency and intensity of eye rubbing have different effects on the cornea.In susceptible population, eye rubbing causes severer damage to the cornea and more serious consequences.Eye rubbing damages the cornea by direct mechanical action, raising corneal temperature and intraocular pressure and releasing inflammatory factors resulting in cell apoptosis.Avoiding eye rubbing is of great significance in delaying the development of keratoconus.Reducing the rubbing time and frequency of patients with keratoconus by treating the primary disease causing eye rubbing and distracting them can reduce the occurrence and slow down the progression of keratoconus, and the life quality of patients can be improved.In this review, the role of eye rubbing in the etiology of keratoconus was elucidated to provide reference for the treatment and prevention of keratoconus.

Objective To explore the association between the concentration of the high-sensitivity C-reac-tive protein(hs-CRP) and acute myocardial infarction(AMI).Methods The concentration of hs-CRP and serum cholesterol were determined by latex-enhanced immunoturbidimetry in 356 patients with AMI and 356 healthy con-trols.Results The concentration hs-CRP was significantly higher in patients with AMI[(18.6±6.9)mg/L ]than in healthy controls[(2.5±1.7)mg/L,P<0.01].and so the concentration of triglyceride(TG)and low-density lip-oprotein(LDL-C)(P<0.05).Conclusion The concentration of serum hs-CRP can predict the risk of AMl with higher prediction value than TG and LDL-C.

This report presented a male patient aged 69 years,who was admitted into our hospital for fever,hemoptysis and chest pain.Chest X-Ray showed shadows on the right lung and pleural thickening.The effect of broad spectrum antibiotic therapy was poor.With the disease progressed,pleural effusion appeared on the right side.Blood culture showed methicillin-resistant staphylococcus aureus.Pleural effusion tests indicated pyothorax,but the effects of closed chest drainage and sensitive antibiotic therapy were poor.After disentangling with open thoracic exploration,the right middle lobe was resected and the right lung lobe pathology showed Wegener granulomatosis.His blood antineutrophil cytoplasmic autoantibodies was negative.The paranasal sinus CT scan and renal function showed no abnormalities.The definitive diagnosis was pulmonary limited Wegener granulomatosis.

ObjectiveTo analyze the correlation between the changes of myocardial enzyme level in serum before and after radiotherapy and dose - volume histogram ( DVH ) parameters of the heart.Methods A total of 102 patients with 68 cases of lung cancer and 34 cases of esophageal cancer were recruited.All patients received three-dimensional conformal radiotherapy (3DCRT) or intensity-modulated radiotherapy (IMRT),with the radiation beams passing through the heart.Aspertate aminotransferase (AST),creatine kinase (CK),creatine kinase isozyme ( CK-MB ),lactate dehydrogenase ( LDH ),α-hydroxybutyrate dehydrogenase (α-HBDH) were determined in the serum before and after radiotherapy.All the enzyme levels before and after radiotherapy were compared through paired t-test.Independent sample t-test was conducted between sub-groups.And the dose-volume histogram (DVH) parameters of the heart were calculated ( the volume percentage of heart receiving dose equal to or exceeding x Gy ( Vx ).The correlation between myocardial enzyme level and DVH parameters was analyzed through Pearson method.Results Serum AST,CK-MB,LDH,α-HBDH levels increased significantly after radiotherapy ( 19.42∶ 27.89,14.72∶19.57,178.80 ∶ 217.57,140.32 ∶ 176.25,t =-3.39 - -6.92,all P=0.000).In Group IMRT,significant correlations between the increase of myocardial enzyme concentration and DVH parameters of the heart are found,AST with V20,V25,V30 of heart ( r=0.302 - 0.431,P =0.039 - 0.003 ),CK with V30of heart (r=0.345,P=0.013),and CK-MB,LDH,α-HBDH with V25,V30(r=0.465 -0.376,P=0.001-0.005).In Group CRT,there are significant correlations between changes of CK-MB,LDH level and V30 of heart (r =0.330,0.274,P=0.014,0.033),α-HBDH and V25,V30,and V35 of heart (r=0.270-0.331,P=0.046-0.014).When the irradiation dose was more than 50 Gy,significant correlations were found between the concentration changes of AST,LDH,α-HBDH and V25,V30 of heart (r=0.256-0.359,P =0.019-0.006),CK-MB and V30(r=0.233,P=0.037).When the irradiation dose was 50 Gy or less,only the concentration change of serum CK has significant correlation with V5 and V45 of heart (r=0.581,0.536,P=0.023,0.043).ConclusionsThere exists certain correlations between changes of myocardial enzymes level before and after radiation and DVH parameters of the heart,which indicates that the DVH parameters of heart are helpful to evaluate the radiation-induced myocardial damage.
