Retinoblastoma (RB) is a common intraocular malignant tumor of infants.It not only seriously threats children's eyesight,but also endangers their lives.RB develops from the immature cells of retina and its occurrence is closely related with the tumor suppressor gene RB1.The inactivation of two alleles of RB1 is the basis of RB occurrence and development.With the rapid development of biological technology,RB gene related research has made great progress.Researches showed that there are many changes in the chromosome level of RB.Many genes are also involved in the development and progression of RB,including oncogene MYCN,murine double minute 4 (MDM4,also known as MDMX),driver protein family members 14 (K IF14),DEK,E2F3,tumor suppressor gene calcium 11 (CDH11) and so on.This review summarizes the progress in gene research of RB,reveal pathogenesis of RB on DNA molecular level and provides a scientific basis for clinical doctors to formulate effective therapeutic plans.

With advances in surgical techniques,laparoseopic surgical instruments and constant equipment innovation,minimally invasive surgery has become the main stream of this century.Wide range of applications of endoscopy and laparoscopy as the representative of the revolutionary changes in diagnosis and treatment of digestive diseases since the second half of last century is the main symbol.Patients obtained benefits from the minimally invasive technique to reduce the trauma and pain,shorten the course of treatment,and gain rapid recovery.Singleincision laparoscopic surgery (SILS) is proposed in recent years.It differs from conventional multiports laparoscopic surgery,with only a small 2-3 cm incision at the body's natural scar-umbilicus as the approach to assist laparoscope and surgical instruments into the abdomen cavity.In this paper,the surgical experiences of SILS based on 800 cases and understanding of the SILS at home and abroad were presented to talk about the application of SILS technique in digestive surgery.

Preterm birth is the main factor affecting the lives and quality of life for premature infants,which is also the main cause for a large economic burden on family,society and medical system.It has been confirmed that the bad neurodevelopment outcome can be effectively prevented by early intervention programs,which are including therapeutic developmental interventions targeting the infants,as well as psychosocial support and education for parents.This review summarizes early intervention programs for improving developmenr outcome in recent years.

Objective To Observe the effects of treating primary trigeminal neuralgia with modified Shaoyao-Gancao decoction and carbamazepine. Methods 76 patients with primary trigeminal neuralgia were randomly divided into a treatment group and a control group, 38 patients in each. The treatment group was treated with modified Shaoyao-Gancao decoction and carbamazepine; and the control group was treated with carbamazepine only. Clinical curative effect, pain improvements and adverse reactions were observed after the treatment and 6 week follow-up. Results The total effective rate was 89.3%and 75.5%in the treatment group and the control group respectively, the difference was statistically significant(P=0.043). The onset frequency, duration, degree of pain were all improved in both groups after the treatment and 6 week follow-up[treatment group after the treatment is (0.54±0.78), (2.15±1.73), (1.58±1.26), 6 week follow-up is (0.24±0.63), (1.36±1.03),0.86±1.95);control group after the treatment is (1.98±1.68), (3.96±1.49), (3.02±1.45), 6 week follow-up is (1.06±1.78), (1.97±1.69), (2.13±1.54), P<0.05],and the treatment group was better than the control group(P=0.040 and 0.039 respectively). Conclusion Modified Shaoyao-Gancao decoction combined carbamazepine has good clinical curative effect in treating primary trigeminal neuralgia.

New method of prostate cancer has grown more precise with the development of medical imaging.Multi-parametric MRI targeted biopsy and fusion biopsy reduce the cores,at the same time they have similar positive rates compared to systematic biopsy.The most used biopsy methods are still transrectal guided transrectal biopsy and transperineal biopsy in China.If we can predict biopsy result before the operation by physical and laboratory examination,it will help improve the detection rate and avoid repeating biopsies.And it has been indicated that age,tPSA,PSAD,fPSA/tPSA,PV,DRE,PHI and PCA3 are the predicting factors.Chinese Prostate Cancer Consortium Risk Calculator is fit for Chinses people.

This article introduces the explorations in improving minimally invasive therapies and techniques for intra-and extrahepatic bile duct stones in this center,including laparoscopic choledocholithotomy without the placement of T tube,laparoscopic partial hepatectomy for the treatment of intrahepatic bile duct stones using an anastomosis stapler for liver partition,and modification of percutaneous transhepatic cholangioscopy.The improved therapies and techniques above have achieved good clinical effects,and a scientific judgment of their clinical effects still depends on a large number of cases and randomized controlled clinical trials.

OBJECTIVE:To change Chinese current irrational drugs use condition so as to promote rational drug use.METHODS:To analysis the causes of the irrational use of drugs in our country and some countermeasures were put forward.RESULTS&CONCLUSION:The situation of irrational use of drugs in our country is quite serious,there is a long way to go before we can use drugs in a rational way,which needs the co-efforts of functional authority department of the government,hospitals,doctors and pharmacists,as well as the attention and cooperation of people in the whole society.

Endogenous NO and CO have been identified in the recent years as signaling molecules and act as the messengers in the body . Both of them have identical characteristics in the mechanism of production and action. Many evidences indicated that NO and CO play important roles in physiological and pathophysiological processes in the prostate. This review highlights the current ideas on localization and function of them in the prostate. We also discussed the relationship between the gaseous messengers and the prostatic diseases.

Objective To explore the effect of PCEA on intestinal peristalsis.Methods 120 patients with ASA Ⅰ～Ⅱ lower abdominal or lower limbs surgery were randomly divided into four groups with 30 cases each and received PCEA at the end of operation sespectively.Group A were given 0.0002% fentanyl,0.2% Ropivacaine and 0.005 % Droperidol;0.01% morphine,0.2% Ropivacaine and 0.005% droperidol in group B;0.2% Ropivacaine in group C;0.9% saline in group D.Postoperative analgesia was provided by PCA pump with LCP model.Results Satisfactory analgesia in group A was 93%,97% in group B 47% in group C and 13% in group D.Both group A and B did not show any significant difference in the analgesic effects(P＞ 0.05).Satisfactory analgesia in group A and B were significantly better than in group C and D(P＜0.05).The renewal of intestinal peristalsis were significantly faster in lower limbs surgery patients than lower abdominal patients(P＜ 0.01),but it did not show any significant difference in the same kinds of surgery in four groups (P＞0.05).Conclusion Both group A and B can get a satisfied analgesia effect;intestinal peristalsis of lower limbs surgery patients renewed were shorter than in lower abdominal patients.

Abnormality of sphincter of Oddi is divided into the anatomical and functional ones. Anatomical abnormality includes stenosis and insufficiency, and the dyskinesia of sphincter of Oddi is composed of hypermotility and hypomotility. Many biliopancreatic diseases are associated with the abnormality of sphincter of Oddi, which include congenital pancreaticobiliary maljunction, gallstones, primary choledocholithiasis and hepatolithiasis, post-cholecystectomy syndrome, and pancreatitis. The proper acknowledgement of abnormality of sphincter of Oddi is of importance to improve the diagnosis and therapy of corresponding biliopancreatic diseases.
