Objective To investigate a new method in correction of epicanthus.Methods Asymmetrical Z-plasty was used in correcting epicanthus and lengthening palpebral fissure in 42 cases with 84 eyes.It could be combined with double-eyelid-blepharoplasty to create beautiful eyes.Results All 42 cases with 84 eyes had satisfactory outcome after half a year to 2 years follow-up.The epicanthus scar was conspicuous in the first 6 weeks and it subsided gradually.In the three cases.the hypertrophic scar occurred in the epicanthus,but it softened and became inconspieuous 6 mouths after operation.Conclusion Asymmetrical Z-plasty is a new and reliable method for correction of epicanthus with inconspicuous scar and little chance of recurrence that can be widely used.

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.

Objective To observe the effects of autologous myoblast transplantation on endplate regeneration and neuromuscular function restoration following direct nerve implantation (DNI) in rats so as to offer experimental basis for the use of myoblasts in neural regeneration area and further lay foundation for the research using myoblasts as transgenic carriers. Methods A total of 20 male SD rats were randomly divided into experimental group and control group,with 10 rats in each group.Models of DNI in rat gastrocnemius were established.The experimental group was injected with primarily cultured autologous myoblasts to the DNI location,while the control group was injected with isometric medium without autologous myoblasts.The effects of myoblasts on the neuromuscular function recovery following DNI were studied by detecting the tibial functional index (FTI),neuro-electrophysiology and pathohistology.Results The experimental group displayed faster tibial nerve function recovery than the control group (P ＜ 0.01 ).The peak to peak value (PPV) of gastrocnemius neuro-electrophysiology,area under the curve and regenerated endplate number of the experimental group had statistical significances as compared with the control group ( P ＜ 0.01 ). Conclusion Myoblast autotransplantation accelerates the recoveryof neuromuscular function after rat DNI and increases the number of the regenerated endplates.

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.

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 optimize the preparation technology of Buqi tongmai capsule.METHODS: Orthogonal experiment of exeracting Radix Astragali was conducted with crude drugs soaking time,extracting times,amount of water added and decocting duration as factors and the content of astragaloside as index.Orthogonal experiment of exeracting Salvia miltiorrhiza,Ligusticum chuanxiong,Fructus Aurantii Immaturus,Carthamus tinctorius was conducted with crude drugs soaking time,amount of water added and decocting duration as factors and the content of tanshinol as index.RESULTS:Water was adopted for extraction and the concentration of alcohol for precipitate was 70 percent.The optimal technology of exeracting Radix Astragali was to soak the crude drugs for 30 min,decoct for 90 min in 10 times of water for 2 times.The optimal technology of exeracting S.miltiorrhiza,L.chuanxiong,Fructus Aurantii Immaturus,C.tinctorius was to decoct the crude drugs for 90 min,8 times of water for 2 times.CONCLUSION:The preparation processes is feasible,stable and meet the demands in the clinic.

OBJECTIVE: To evaluate application of antibiotics and non-steroidal anti-inflammatory drugs in 3 hospitals of Guang’an and find out the reason of unreasonable use of drug. METHODS: 120,000 prescriptions were randomly collected from inpatient and outpatient departments of 3 hospitals from Jan. 2005 to Jan. 2008, which included 20 000 pediatrics prescriptions. The DDDs and DUI of antibiotics and non-steroidal anti-inflammatory drugs were analyzed statistically. RESULTS: The DUI of 10 kinds of antibiotics and 3 kinds of non-steroidal anti-inflammatory drugs were above 1, which indicated that drug abuse occurred. CONCLUSION: Physicians’ prescribing behavior lack medical rationality and the situation of drug feeding hospital is still critical in primary hospitals.

Exudative erythoma multiforme is a related to the immune function of children with skin and mucosa,damage to its diversity of characteristics of acute non suppurative inflammation,one of the aller-gic diseases.The disease and its pathogenesis is complex,the body can cause multi system and multi organ damage,the cause has not yet entirely clear.In recent years,due to our understanding of the exudative erytho-ma multiforme gradually thorough,both domestic and abroad on the level of diagnosis and treatment of the disease have greatly improved,the prognosis of patients with exudative erythoma multiforme has improved significantly.The progress of the pathology,clinical manifestation,diagnosis and treatment of exudative ery-thoma multiforme were summarized.
