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.

On the basis of status and technical characteristics of rehabilitation training instrument in China, this article summarized theconcept and significance of reliability-based design, introduced the technical target of rehabilitation training instruments and the procedureof building a reliability model. The future prospect of applying reliability-based design to rehabilitation training instruments is also discussed.

Objective To study the value of crater signon coronary section by automated breast volume scanner(ABVS) in diagnosing benign or malignant breast tumours .Methods 70 cases of breast tumours were observed by ABVS and contrast with pathology .The clinical value of ABVS in diagnosing benign or malignant breast tumours was analyzed .Results The sensitivity of crater signon coronary section was 65.5% and the specificity was 90.5%.The difference in benign or malignant breast tumours with crater signwas statistically significant (χ2 =29.76,P<0.05).Conclusion ABVS coronary section with crater signhas important clinical value in diagnosing benign or malignant breast tumours and is a new supplement of two -dimensional ultrasound .

Objective To compare the application effect of vasopressin and oxytocin in intramural myomectomy. Methods 50 in -patients for myomectomy were randomly divided into the observation group and the control group, with 25 cases in each group.By injecting oxytocin around hysteromyoma in the control group,and vasopressin in the observation group,hysteromyoma size,number,operation time,amount of bleeding,postoperative hemoglobin,normal body temperature recovering time,anal exhaust time and hospitalization time were compared in two groups.Results Operation time of the observation group was (86.4 ±1.8)minutes,which of the control group was (112.4 ±1.5)minutes,the difference was statistically significant (t =78.462,P <0.05).Blood loss of the observation group was (68.8 ± 27.6)mL,which of the control group was (130.8 ±37.5)mL,the difference was statistically significant (t =9.415, P <0.05).Postoperative hemoglobin of the observation group was (9.6 ±3.6)g/L,which was higher than (5.4 ± 2.6)g/L of the control group,and the difference was statistically significance (t =9.872,P <0.05).The hysteromyoma size of the two groups showed no significant difference (P >0.05 ).The comparing of normal body temperature recovering time,hospitalization time,anal exhaust time of the two groups were not statistically significant (P >0.05). Conclusion Hemostasis effect was evident after applying vasopressin in myomectomy,which can significantly reduce blood loss,shorten surgery time and reduce hemoglobin changes,it′s better than oxytocin and is worth in clinical application.

Necrotizing enterocolitis is an acute gastrointestinal disease in infants.Recent studies have reported that approximately 25％ to 35％ infants receiving packed red blood cell transfusions develop transfusionrelated necrotizing enterocolitis.The pathogenesis of transfusion-related necrotizing enterocolitis is not clear.This article reviews previous researches and current theoretical perspectives of transfusion-related necrotizing enterocolitts.

The myelodysplastic syndrome(MDS)is a group of clonal haematopoietic stem cell diseases characterized by ineffective haematopoiesis,dysplasia and aberrational expression of cell surface markers.Therefore,immunophenotyping of blast cells,granulocytes and monocytes is helpful to distinguish between MDS and non-MDS.The immunophenotyping is a complicated process.So the uniform diagnostic standard is the key to the comparabe and reliable results.

Uterine arteriovenous fistula (UAVF) is a rare condition,however it can cause life-threatening vaginal bleeding or acute intra-abdominal hemorrhage.Many diagnosis methods may be used,among which angiography is the gold standard of diagnosis.There is no clear treatment guideline so far.Treatments can be made according to patient's age,symptoms,bearing requirement and pathological changes of hemodynamic parameters.

and more rapid.It can provide new evidence for clinical diagnosis and treatment of BV.
