Psoriasis is a common inflammatory autoimmune disease. Angiogenesis is known to be a key pathogenic fea?ture of psoriasis. The elevation of vascular endothelial growth factor (VEGF) has been demonstrated in the skin and plasma of patients with psoriasis. A number of case reports have indicated that VEGF inhibitor is effective in patients with psoriasis. VEGF inhibitors are consisted of three categories:anti-VEGF monoclonal antibodies, VEGF receptor antagonists and tyro?sine kinase inhibitors. This article reviewed the current clinical application and therapeutic potential of VEGF inhibitors in psoriasis .

The target restoration space (TRS) is a required tooth space that should be occupied by an esthetically formed and optimally functioned crown, veneer, or other fixed restoration. It can be either internal of or external of a tooth. Since minimal invasive can't be achieved without a minimal TRS, a precise preparation of slightest damage should conform to the transfer guide based on TRS. This paper introduces the concept, design of TRS, explains how it can be applied in tooth preparation, and helps to better understand a precise and minimal invasive tooth preparation technique.

Objective To investigate the predictive value of serum histone deacetylase 3(HDAC3) ,cystatin C(CysC) and albu‐min levels on a large area of myocardial infarction .Methods According to whether heart failure and (or) cardiogenic shock occur‐ring during hospitalization ,102 patients with acute myocardial infarction(AMI) were divided into the two groups :the non - compli‐cating heart failure and (or) cardiogenic shock group(n= 63) and the complicating heart failure and (or) cardiogenic shock group(n= 39) .Then according to whether the creatine kinase(CK‐MB) peak value was greater than 200 IU /L ,102 AMI patients were di‐vided into two groups :CK‐MB peak values ≥ 200 IU /L group(n= 58) and the CK‐MB peak values < 200 IU / L group(n= 44) .The serum HDAC3 ,CysC and albumin levels were detected at early morning on 2 d of admission in all patients .Results Compared with the non - complicating heart failure and (or) cardiogenic shock group ,serum HDAC3 and CysC levels in the the complicating heart failure and (or) cardiogenic shock group were significantly increased(P< 0 .01) ,while serum albumin protein level was significantly in the occurrence of heart failure and(or)cardiogenic shock group .Compared with the CK‐MB peak value < 200 IU /L group ,serum HDAC3 and CysC levels in the CK‐MB peak value > 200 IU /L group were significantly increased (P< 0 .01) ,while serum albumin level was significantly decreased(P< 0 .01) .Conclusion Serum HDAC3 ,CysC and albumin levels have certain predictive value on a large area of myocardial infarction and conduce to judge the prognosis of patients .

Objective To investigate the distribution and drug resistance of bacteria infection in children with pneumonia between pediatric intensive care ward and respiratory ward,in order to guide clinical treatment.Methods From 2010 January to 2014 January,two-hundred and sixty cases of pneumonia in hospitalized pediatric intensive care ward were included in the severe group,300 patients from respiratory ward into the common group,severe group were divided into the mechanical ventilation group (126 cases),non mechanical ventilation (134 cases),mechanical ventilation were divided into invasive ventilation group (94 cases),noninvasive ventilation group (32 cases).Conventional sputum specimens were detected,bacterial culture,identification and drug resistance of pathogenic bacteria ratio were done in each case,to compare the pathogenic bacteria and drug resistance rate of different groups.Results Both severe group and common group,gram negative bacteria were significantly higher than those of gram positive,But in the severe group,gram negative bacteria ratio was significantly higher than the common group (P ＜ 0.05),while the positive bacteria ratio was significantly lower than that of common group (P ＜ 0.05).Stenotrophomonas maltophilia,Acinetobacter and Pseudomonas aeruginosa ratio in severe group were significantly higher than that of common group (P ＜ 0.05),while the Haemophilus influenzae and Streptococcus pneumoniae in common group was significantly higher than the proportion of severe group (P ＜ 0.05).Stenotrophomonas maltophilia,Acinetobacter,Pseudomonas aeruginosa ratio in ventilation group was significantly higher than that of non ventilation group (P ＜ 0.05),and in the invasive ventilation group was significantly higher than the proportion of noninvasive ventilation group (P ＜ 0.05).Multi drug resistant bacteria detection rate in severe group was significantly higher than the common group (P ＜ 0.05).Conclusion Both pediatric intensive care ward and respiratory ward,bacterial lung infections are dominated by Gram negative bacteria,but bacteria spectrum and drug resistance have obvious difference,multi drug resistant bacteria detection rate in pediatric intensive care ward significantly higher than that of respiratory ward.Mechanical ventilation especially invasive mechanical ventilation may easily lead to drug-resistant strains.

Objective To evaluate the effect of low intensity He-Ne laser irradiation on the level of hydroxyproline in the Achilles tendons of rabbits after experimental tenotomy, and to determine the best irradiation cycle. Methods Twenty-two male New Zealand rabbits, aged 10-12 weeks, were randomly divided into control and experimental groups. The control group received no laser irradiation after tenotomy. The experimental animals were treated with a He-Ne laser (632.8 nm, 18.9 mW) daily for 14 days. The treated animals received 10 minutes, 20 minutes or 30 minutes of irradiation daily. At the 14th day or the 28th day after the operation, the rabbits were sacrificed and the level of hydroxyproline ( Hyp) in their Achilles tendons was measured. Results Hyp was significantly higher in all experimental animals than that in the controls. Hyp level in the 20 minutes group was significantly higher than in the 10 minutes group. Hyp level in the 20 minutes group at the 28th day were significantly higher than at the 14th day. Conclusions He-Ne laser irradiation facilitates the synthesis of collagen and enhances the healing of A-chilles tendons. The best irradiation time might be 20 minutes.

Objective To observe the role of human hepatocarcinoma HepG2 cell culture supernatant on T lymphocyte of the activation, proliferation, IL-2 secretion and inducing apoptosis in vitro. To explore the mechanism of immune escape in tumor.Methods Peripheral blood mononuclear cells (PBMC) were cultured with different concentration of tumor cell culture supernatant. Cell proliferation was examined with standard cytometry and MTT. The apoptotic rate and immune phenotype were analyzed by FACS. The level of IL-2 was determined with ELISA.Results Adding HepG2 supernatant, there was no significant influence in activation of lymphocyte, but the proliferation rat and the secretion of IL-2 were obviously decreased. The lymphocyte apoptosis rate was raised.Conclusion The tumor cell may produce a certain soluble protein, thus escape from the immune surveillance of tumor-bearing host.

Objective:To study the impact factors of psychological distress in patients with first diag-nosed lung cancer.Methods:The cross-sectional study was applied to newly diagnosed lung cancer pa-tients who received treatments in Cancer Center of West China Hospital of Sichuan University in Chengdu from June 201 3 to March 201 5 by distributed questionnaires.The general information of the patients,the hospital anxiety and depression scale (HADS)and distress management screening measure (DMSM) were included in the questionnaire to evaluate the states of distress,pain and the factors related to the distress of the patients.Results:The survey investigated a total of 390 patients with first diagnosed lung cancer,including 291 male patients and 99 female patients.The proportion of the patients with positive anxiety symptom was 26.7% (1 04 /390),with positive depression symptom was 27.7% (1 08 /390), and with positive distress symptom was 30.0% (1 1 7 /390).On the top five problem list of DMSMwere worry,disease treatment,breathing,pain and sleep.The Spearman correlation analysis showed that an-xiety score,depression score,and the pain intensity were positively correlated with the distress.Multiple linear regression analysis showed that gender (β=-0.209,P =0.003),age (β=-0.098,P =0.042),chronic disease (β=0.378,P <0.001 ),and pain score (β=0.1 00,P =0.029)could affect the distress of the patients.Smoking (β=0.1 1 1 ,P =0.041 )could affect the anxiety of newly diagnosed lung cancer patients.Conclusion:The gender,age,chronic disease and pain score of the patients are the independent factors of the psychological distress of first diagnosed lung cancer patients.Smoking is the predictive factors of the patients with anxiety.Controlling the pain intensity and the clinical process of chronic disease of the patients actively,solving the sleep and breathing problem and helping the patients to quit smoking progressively could alleviate the psychological distress of the patients.
