Gap junctions are membrane structures made of intercellular channels that allow directly exchange of material and information between adjacent cells. It is the structural basis of gap junctional intercellular communication. Gap junction is aberrant frequently in variety of cancers, which relatives with tumor genesis and metastasis. New anti-cancer drugs targeting gap junctions will be a new direction for tumor treatment.

In the past decades,more and more mutant genes that cause inherited retinal diseases have been found.Meanwhile,many naturally occurring animal models have also been found to show similar gene mutations and phenotypes as the human inherited retinal diseases,which have led to the development of a variety of therapeutic strategies for those traditionally incurable inherited diseases.These models include rod degeneration (rd) mice,such as rd1 model,rd10 model and nmf137.To compare the efficacy of these strategies,this article briefly reviews the recent progress in the treatment of the mouse models with mutations in the subunit of rod phosphodiesterase (Pde6b)gene by pharmaceutical,stem cell and gene therapy in order to find a more effective treatment for retinal degeneration.

The future prospect of applying reliability-based design to rehabilitation training instruments is also discussed.

Objective To explore the treatment outcomes of intensive pulsed light (IPL) in combinationwith rb-bFGF in patients with telangiectasia.Methods A total of 57 patients with telangiectasia were randomly divided into 2 groups:group A,IPL540nm (n=32);group B,IPL with rb-bFGF (n=25).The intense pulsed light with 540 nm wavelength,energy density of 14-17 J/cm2 and pulse width of 10-12 ms was used for 3-5 times at intervals of 4-5 weeks.Results Fifty-seven patients completed the Study with maximal 5 treatment sessions,100% improvement was observed in 15.62% and 64.00% at group A and group B respectively after 1-2 treatment sessions,but in 62.5% and 84% after 3-4 treatmentsessions.There was significant difference in treatment sessions between the groups A and B (P

OBJECTIVE To promote the enforcement of Prescription Administrative Policy(on trial). METHODS: Signifi_cance of Prescription Administrative Policy(on trial) was analyzed and the problems existing in its enforcement were discussed. RESULTS&CONCLUSION:Prescription Administrative Policy(on trial) needs to be improved to become more reasonable, The more practicable enforcement should be expected through practice.

Objective To compare the clinic effects of gatifloxacin and fleroxacin on respiractory infections.Methods 160 patients of low-moderate respiractory infections were divided into observation group (80 cases) and control group (80 cases).Under common therapy,the observation group accepted gatifloxacin injection while the control group accepted fleroxacin injection.The effective rate,bacterial clearance rate and untoward effect were compared between the two groups.Results The effective rate of observation group was obviously higher than control group (88.8％ vs 72.5％,x2 =3.16,P ＜ 0.05).The bacterial clearance rate of observation group was obviously higher than control group (90.0％ vs 78.8％,x2 =6.28,P ＜ 0.05).There were 5 cases of nausea and vomiting in observation group while 3 cases of nausea and 2 cases of nausea and vomiting in control group.The diverse of untoward effect of two groups had no significance (x2 =0.03,P ＞ 0.05).Conclusion Gatifloxacin has a better clinic effect than fleroxacin.Gatifkoracin doesn't increase the untoward effect on respiractory infections.

Objective To explore the clinical curative effect of central venous catheter drainage in treating pleural effusion.Methods 100 cases with pleural effusion were treated by the central venous catheter drainage.The curative effect,complications and adverse reactions were observed.Results Ater treatment for 12 ～ 28d,catheter drainage of 100 patients were all successful at the first time.The clinical effect:completely relieve 40 cases(40.0％),clinical partial remission 47 cases(47.0％),inefficient 13 cases (13.0％),and the total effective rate was 87.0％.There were some complications:pneumothorax 1 case,hemorrhage 2 cases,infection 1 case,pleural reaction 3 cases,pain 3 cases,subcutaneous emphysema 2 cases and take off the tube 1 case,the incidence rate of complications was 13.0％.Conclusion Central venous catheter drainage in t.reating pleural effusion has significant curative effect,which is worthy of clinical application.

OBJECTIVE:To prepare Dexibuprofen Syrup and establish a method for its quality control.METHODS:Dexibuprofen Syrup was prepared with dexibuprofen as main ingredient and the content of dexibuprofen was determined by HPLC.RESULTS:The preparation appeared as yellowish or yellowish-brown sticky liquid and its property was in line with the standard specified in Chinese Pharmacopeia(2005 Edition).The linear range of dexibuprofen was 0.100 6～0.502 8 mg?mL-1(r=0.999 9)and its average recovery rate was 99.65%(RSD=0.64%).CONCLUSION:This preparation is simple and feasible in preparation technology and controllable in quality.

Objective To study the application effect of PDCA management mode in the teaching process of practice nurses in spine surgery to reduce the occurrence of nursing errors. Methods A total of 35 practice nurses in spine surgery from March 2014 to March 2015 received the routine teaching mode were set as control group, and 35 practice nurses from April 2015 to April 2016 implemented PDCA management mode were set as intervention group. The occurrence rate of nursing adverse events in two years was observed, and the interns for clinical teaching evaluation model of quality and satisfaction and the intern examination results were summarized. Results The incidence of nursing adverse events was 22.86% (8/35) in control group, and 2.86% (1/35) in intervention group, the difference was statistically significant (χ2= 17.85, P = 0.00). The intern teacher for clinical teaching content arrangement, teaching attitude, detail guidance and skills training indicators evaluation score were (15.46±1.03), (14.18±1.06), (14.61±1.11), (13.30±1.07) points in control group, and (18.26±1.00), (18.48±0.51), (19.43±0.21), (19.16± 0.28) points in intervention group, the differences were statistically significant (t = 11.54- 31.34, P <0.01). The interns given theory and skills examination results were (80.15±1.61), (85.16±1.02) points in control group, and (93.10±2.01), (91.06±2.03) points in intervention group, the difference was statistically significant (t = 29.75, 15.36, all P = 0.00). The clinical teaching satisfaction was 57.14% (20/35) in control group, and 80.00% (28/35) in intervention group, the difference was statistically significant (χ2=12.12, P=0.00). Conclusions PDCA management model applied to clinical practice in department of orthopedics teaching process, can effectively improve the intern theory knowledge and skills to master the ability, most of the interns examination results are more optimistic, and for this kind of management pattern for the process of teaching evaluation of higher satisfaction, the teachers care under the guidance of intern nursing mistake, nursing adverse events is low, this method is worthy of promotion.

Despite survival of extremely preterm infants has increased over recent years,bronchopul-monary dysplasia( BPD) remains both a major cause of mortality and one of the most common complications with implications into adulthood on respiratory and neurologic health. Steroids have a clear beneficial effect on BPD,but there is much debate surrounding the use of corticosteroids on the prevention and treatment of BPD. Careful consideration of the available data along with the clinical characteristics of the individual infant is required before being introduced into therapy.
