Retinoblastoma (RB) is the most common intraocular malignant tumor in children. With advanced clinical technologies there are more and more methods available to treat retinoblastoma, and make it is possible to delivery individualized protocol combined traditional treatments with modern regimen to patients now. In order to improve the survival rate and the life quality of RB patients in China, it is very important to make a suitable system of standardized therapy based on results from developed countries and health policies of our own country.

Objective To assess the value of CT in the diagnosis of PRF,and analyze the reason of misdiagnosis. Methods Retrospectively analyze the CT data of ten patients with retroperitoneal fibrosis,which were confirmed by the clinical pathology.All the patients underwent CT scan and enhanced scan.Two experienced physicians using the blind method to evaluate the location, boundary, density, invasion on the surrounding tissue and enhancement of retroperitoneal fibrosis lesions respectively.Results All patients with CT scan findings were retroperitoneal irregular-shaped soft tissue lesions,which was similar to muscle density.6 cases with surrounding the retroperitoneal vessel, 2 cases with expansion and hydrops of renal pelvis and ureter.By enhanced scan,9 cases with different degrees of enhancement,1 case without obvious enhancement.6 cases were misdiagnosed as retroperitoneal schwannoma or lymphoma. Conclusion CT can show the characteristics of retroperitoneal fibrosis. Comprehensively analyze various imaging findings is helpful for the diagnosis of retroperitoneal fibrosis. Misdiagnosis reason is mainly due to retroperitoneal fibrosis is a rare disease,and understanding of this disease in imaging findings is insufficient in the daily work.

BACKGROUND:Physical structure and inorganic composition of composite calcium phosphate bone implants are similar to human bone, and the implants have good bioabsorbable ability and biocompatibility. Studies have confirmed that Dipsacus powder can significantly improve the speed of bone defect repair.
OBJECTIVE:To study the effects of Dipsacus asperoides/composite calsium phosphate bone implant material in the repair of bone defects.
METHODS:Bone defects of 1.0 cm×0.5 cm×0.3 cm were made on the bilateral mandibular bodies. The right side was implanted with Dipsacus asperoides/composite calsium phosphate bone implant as experimental group and the left side implanted with calcium phosphate bone material served as control group. Samples were col ected at 4, 8, 12 weeks after implantation for gross observation, cone beam CT, scanning electron microscope observation and histological observation.
RESULTS AND CONCLUSION:(1) Gross observation:the osteogenic speed, degradation rate and hardness in the experimental group were higher than those in the control group. (2) Cone beam CT detection:the implant in the experimental group was more tightly integrated with the surrounding tissues than that in the control group, and the degradation speed in the experimental group was higher than that in the control group. (3) Scanning electron microscope observation:there were many fibrous connective tissues between the implants and the surrounding tissues in the two groups, which was more obvious in the experimental group than the control group. With time gone, the implants were combined with the surrounding tissues more tightly. (4) Histological observation:the osteogenic speed and activity in the experimental group were superior to those in the control group. These findings indicate that Dipsacus asperoides combined with composite calcium phosphate bone implant can accelerate bone repair.

Objective To observe and analyze the changes of prostaglandin E2 (PGE-2)and elastase (EA)levels in the pulp blood of the patients with carious tooth complicated with exposed pulp and its influence on the curative effects of direct pulp capping treatment.Methods 80 cases of the patients with carious tooth complicated with exposed pulp treated with direct pulp capping treatment were selected as the observation group and 40 cases of the patients treated with normal removal of impacted third molar were selected as the control group.The levels of PGE-2 and EA in the pulp blood of the patients in the two groups before the treatments were detected and compared.A one-year follow-up was employed for the patients in the observation group and the curative effects were evaluated and compared.Results The levels of PGE-2 and EA in the pulp blood of the patients in the observation group were 132.28±63.55 ng/ml and 114.36±19.57μg/ml respectively,and the levels of PGE-2 and EA in the pulp blood of the patients in the control group were 0.61±1.26 ng/ml and 19.38±6.34μg/ml respectively.There were statistically significant differences between the two groups (t=43.129,29.675,P<0.05). There was a positive relationship between the PGE-2 level and EA level in the pulp blood of the patients in the observation group (r=0.782,P<0.05).The levels of PGE-2 and EA in the pulp blood before the treatment of the patients with suc-cessful effects were 84.63±13.17 ng/ml and 68.25±8.16μg/ml,and the levels of PGE-2 and EA in the pulp blood before the treatment of the patients with failed effects were 177.35±41.42 ng/ml and 152.36±16.28μg/ml.There were statisti-cally significant differences between the two types of patients (t=31.578,21.556,P<0.05).Conclusion The patients with carious tooth complicated with exposed pulp show the significantly increased expression levels of PGE-2 and EA in pulp blood.The higher expression levels of PGE-2 and EA before the treatment could put adverse influence on the curative effects of direct pulp capping treatment.The clinicians should give the comprehensive consideration to the specific condition of pa-tients to choose the proper treatment methods.

Objective To investigate the efficacy of low dose thalidomide combined with chemotherapy in treatment of multiple myeloma(MM)and the clinical curative effect of the treatment method.Methods From June 2010 to June 2012,80 patients were diagnosed with multiple myeloma as the research object in Traditional Chinese Medicine Hospital of Haining,randomly divided into control group and observation group,with 40 cases in each group.The control group adopted conventional chemotherapy,the observation group were given low dose thalidomide combined with conventional chemotherapy.The clinical effect and adverse drug reactions were compared. Results The total effective rate of observation group (87.5%)was significantly higher than that of control group(65.0%)(P<0.05).The adverse reactions were 87.5%(35/40)in observation group and 100.0%(40/40)in control group,there was no significant difference between the two groups.The mean progression-free survival(PFS)and overall survival(OS)in observation group(5.5 ±1.2 months;1 1.5 ±2.4 months)were higher than those in control group(3.7 ±0.8 months;8.5 ±1.3 months)(P<0.05 ). Conclusion Low dose thalidomide combined with conventional chemotherapy in the treatment of multiple myeloma can improve clinical effect and decrease recurrence rate,with high safety and less adverse reactions.

As the burden of anesthesiology teaching is heavy in undergraduate course, teachers can communicate with the students by nonverbal behaviors, such as eye contact, silent language, facial expression, paralanguage, which can make class atmosphere active, develop harmonious teacher-student relationship, and improve the quality of class teaching. Teachers of anesthesiology should take some measures, such as rehearsing lessons, summing up the experience of the lessons in time, accu-mulating the experience of nonverbal behaviors, and doing some exercise for the nonverbal behavior as much as possible, so as to set up an excellent atmosphere for teaching ,and meanwhile improve the quality of anesthesiology teaching.

Chemotherapy remains the main treatment for many cancer patients. However, P-glycoprotein (P-gp) mediated multidrug resistance poses severe challenges to current chemotherapies. As ideal vectors to overcome drug resistance, nanovehicles are extensively explored for cancer treatment by diverting P-gp mediated drug efflux mechanisms. Surface engineering of nanocarriers has attracted great attention for targeted therapeutic delivery. The folate receptors, one of the most researched targets in cancer therapeutics, are over-expressed in several carcinomas. And folate has become one of the most investigated ligands in cancer therapeutic direction due to its small size, easy conjugation to nanocarriers, nontoxic, nonimmunogenic nature, and well stability in storage or in circulation. This review discussed the current status of folate functionalized nanoparticles in diverting P-gp mediated drug efflux mechanisms.
