Paroxysmal supraventricular tachycardia (PSVT) is one of the frequent cardiovascular diseases.In recent years, cryoablation has become a research hot spot for PSVT treatment.Theoretically, its operability and safety are both better than those of radiofrequency ablation.Cryoablation can significantly reduce risk of ablation complications, but how to reduce recurrent rate after cryoablation is still a problem in the future.The present article made a review on main therapeutic methods of PSVT, especially application of cryoablation.

MDM2-binding protein(MTBP)factor is a binding protein of MDM2,and MDM2 gene and involved in the development of cancer as an important gene ,which has been studied for a long time .It has been demonstrated that MTBP could regulate biological processes such as metabolism ,growth,and apoptosis of cells .In the past few years ,some studies have found that MTBP is down -regulated in variety of malignancies ,which is as-sociated with the progression and the prognosis of these tumors .MTBP may be a potential target for the treatment of many kinds of malignant tumors .This paper reviews the research pregressof MDM 2-binding protein on canc-er.

Objective To investigate the effect of protection motivation intervention on patients with diabetic cataract after implantable collamer lens implantation. Methods A total of 118 diabetic cataract patients were divided into 2 groups (59 cases each) by random digits table method. The control group received routine ophthalmic nursing and the observation group was given protection motivation intervention based on the routine nursing. The change of the plasma glucose, postoperative visual acuity and the quality of life were evaluated. Results The blood glucose on the morning of the operation day and one day after operation in the observation group was (8.27±1.25) mmol/L, (9.52±2.44) mmol/L, which was significantly lower than that of the control group, (10.49 ± 1.48) mmol/L, (12.77 ± 3.36) mmol/L, the difference between the groups was statistically significant (t=-5.392,-6.755, P<0.01). After 1 month and 3 months, the vision of the observation group was 0.64±0.22, 0.67±0.30, which was higher than that of the control group 0.56± 0.18, 0.58 ± 0.20, in which the postoperative blindness or low vision rate was 3.95%(3 eyes) in the observation group, and 13.51%(10 eyes) in the control group(t/χ2=2.492, 2.209, 4.013,P<0.05). The quality of life in the observation group was 7.70±1.13 and 5.22±1.48 in the control group, there was statistical significance between the two groups(t=3.660, P < 0.05). Conclusions Application of protection motivation intervention on diabetic cataract patients can improve their postoperative vision and quality of life.

Objective To systematically evaluate the type and magnitude of effectiveness of pulmonary rehabilitation program on patients diagnosed with chronic obstructive pulmonary disease (COPD) in none-acute phases.Methods Two investigators independently searched three databases including Cochrane library,Pub Med and CNKI to collect randomized controlled trials about Pulmonary Rehabilitation Program on COPD Patients.A total of 17 trials were included.The quality of these RCTs was evaluated by two investigators and the combination of study results was conducted using RevMan 5.0.2 software.Results Pulmonary Rehabilitation Program could improve COPD patients' exercise tolerance,quality of life,lung function and blood oxygen level.It was also beneficial to patients' discomforts including dyspnea and fatigue.Conclusions The meta-analysis had identified a significant effect of pulmonary rehabilitation program on COPD patients,so nurses are suggested to integrate effective programs into clinical practice.

Objective To observe the effects ofLinggan Wuwei Jiangxin Decoction on contents of cAMP, cAMP dependent PKA and AQP5 of model rats with clod phlegm-fluid lying latent in the lung asthma;To discuss its mechanism.Methods Ovalbumin intraperitoneal injection and atomization motivation + cold stimulation were used to establish models. Ninety rats were randomly divided into blank control group, model group, hexadecadrol group, andLinggan Wuwei Jiangxin Decoction low-, medium-, high-dose groups. All administration groups were treated with relevant medicine. The levels of cAMP, PKA, and AQP5 were detected by ELISA.Results Compared with the blank control group, the levels of cAMP, PKA, and AQP5 of rats in model group decreased obviously (P<0.05). Compared with the model group, the levels of cAMP, PKA, and AQP5 of rats in all administration groups increased (P<0.05), which increased dramatically inLinggan Wuwei Jiangxin Decoction high-dose group.ConclusionLinggan Wuwei Jiangxin Decoction can regulate the normal secretion of cAMP, PKA, and AQP5 in serum of rats with clod phlegm-fluid lying latent in the lung asthma, increase secretion of air passage liquid and decrease mucoprotein concentration, through which plays the role of treating asthma.

Objective Effect of psychological intervention on functional rehabilitation of femoral supracondylar fractures.Methods 84 type C fracture patients according to AO criteria for the diagnosis were collected,and randomly divided into intervention group(n=42)and control group(n=42)according to patient sex,age,fracture condition,cultural degree balanced matching principle.The control group was given conventional treatment and fracture features of health guidance,the intervention group in addition to conventional treatment and rehabilitation guidance.Comprehensive mental intervention applied 4 times on postoperative 3 days,the 2nd,3rd,4th week.Self-anxiety scale and self-depression scale were used before operation and 6th month after operation.Results The anxiety and depression scores in two groups before intervention showed no significant difference P>0.05).6 months after the operation,the anxiety score(41.6±9.4 vs 48.7±8.5)and depression score(40.6±7.6 vs 47.4±9.2)in intervention group apparently decreased than that in control group(P<0.01).Function restoration of knee joint in different effect showed better than control group(u=-2.0591,P<0.05).Conclusion Psychological intervention can effectively promote the functional recovery of patients with femoral supracondylar fractures and promote anxiety and depression mood.

OBJECTIVE:To investigate the impact of the drug price limits policy on the consumption of anti-infectives in our hospital.METHODS:The consumption sum and DDDs of the chief categories of anti-infectives in our hospital before and after the adoption of drug price limits policy(between Oct.,2004 and Sept.,2005 and between Oct.,2005 and Sept.,2006)were analyzed statistically.RESULTS & CONCLUSION:Both DDDs and consumption sum of the chief categories of anti-infectives in our hospital decreased markedly since the adoption of drug price limits policy.

Objective To investigate the in vitro effects of compound Chinese herbal medicine Zilongjin on prostate cancer cell lines. Methods MTT assay,flow cytometry, colony on soft agar,and fluorescence microscopy were used to observe the effects of Zilongjin on anti proliferation,inhibition of clonal growth,cell cycle arrest and apoptosis induction.RT PCR method was used to study the regulative effect of Zilongjin on prostate marker genes PSA,AR,apoptosis related genes Bcl 2,Bax and tumor suppressing gene p16. Results Zilongjin caused notable anti proliferative effect,and induced G 0/G 1 phase arrest dose dependently on LNCaP,DU 145 and PC 3 cell lines.Inhibition of cell growth by 50% (IC 50 ) was observed with Zilongjin at concentrations of 0.79,0.42 and 0.52 mg/ml,respectively.Apoptosis induction was seen in LNCaP and DU 145 cell lines.Zilongjin also caused inhibition of clonal growth of DU 145 cell line.In addition,Zilongjin down regulated the expression of PSA,AR and Bcl 2 genes in LNCaP cell line;and down regulated Bcl 2,up regulated Bax and p16 genes expression in DU 145 cell line. Conclusions It is demonstrated that Zilongjin has antitumor action through anti proliferation,inhibition of clonal growth,G 0/G 1 phase arrest,apoptosis induction and regulating the expression of PSA,AR,Bcl 2,Bax and p16 genes.
