Objectives:To evaluate the efficiency of packing jaw defects with a composite of coral and bone marrow.　Methods:Twelve patients (9 with jaw cyst and 3 with ameloblastoma) underwent enucleation of jaw lesion and packing with a composite of coral and bone marrow.Repair of the bone defects was evaluated at 1 week,1,6 and 12 months postoperatively by clinical examination and X-ray films.　Results:Wound healing after the operations on 10 patients was uneventful,and definite ossification around the implanted material could be detected at 1 month postoperatively.A lot of bone formation and partial resorption of coral were observed at 6 months postoperatively.Complete resorption of coral and complete bone repair were obtained at 12 months postoperatively.Wound breakdown was observed on two other patients,and the composite had to be removed completely.　Conclusions:A composite of coral and bone marrow may enhances bone healing in jaw defects after cyst or ameloblastoma removal.

SUN Shu-chun,the chief researcher,is one of the famous expert of osteo-traumatology of TCM.He makes systematic sort and study on chirismus on basis of succeeding experience predecessors and his own years of clinic experience.He is good at treating cervical syndrome with TCM chirismus,especially combine it with drugs.In osteo-traumatology academic circles,he is called "the best doctor at home".Professor SUN advocates that the rule of applying various therapies according to different conditions,combination of rigid-flexible,light,skill,gentle,harmony should be obey when we use chirismus.His diagnostic and therapeutic methods and thoughts are original and ingenious.In this article,the author analyzes the academic experience of tendon trauma of professor SUN.

ObjectiveTo study the effect of testing amino acids levels in brain microdialysate by method of high performance liquid chromatography (HPLC) with α-aminobutyric acid (AABA) as the internal standard.MethodsReversed phase high performance liquid chromatography (RP-HPLC), orthophthaladehyde (OPA) precolumn derivatization method and fluorescence detector were used. The separation was performed using an ODS-C18 column. AABA, an isomeric compound of GABA, served as the internal standard, phosphate buffer solution and methanol as the mobile phase, gradient elution lasted in 35 min.Results7 kinds of amino acids and internal standard were separated completely. The mean recovery of amino acid was 88.2%—102.3%. The mean correlation coeffeicient of the linear relationship was 0.998±0.0015.Limits of detection for amino acids were 1.0—8.6 ppm respectively.ConclusionThe method mentioned above is simple and sensitive for operation, and can be used for determined levels of amino acids in microdialysate.

Due to lack of the practical technique to measure the biomechanical properties of the ocular cornea in vivo, clinical ophthalmologists have some difficulties in understanding the deformation mechanism of the cornea under the action of physiological intraocular pressures. Using Young's theory analysis of the corneal deformation during applanation tonometry, the relation between the elasticity moduli of the cornea and the applanated corneal area and the measured and true intraocular pressures can be obtained. A new applanation technique has been developed for measuring the biomechanical properties of the ocular cornea tissue in vivo, which can simultaneously acquire the data of the applanation area and displacement of the corneal deformation as well as the exerted applanation force on the cornea. Experimental results on a rabbit's eyeball demonstrated that the present technique could be used to measure the elasticity moduli and creep properties of the ocular cornea nondestructively in vivo.

OBJECTIVE:To analyze the situation of the minimum sales package unit,and to provide reference for standardiz-ing package. METHODS:According to related regulations of New Edited Materia Medica(17th edition)and package inserts,373 kinds of oral drugs,57 kinds of oral drugs for lowering blood glucose,blood lipid and blood pressure,6 kinds of second kind psy-chotropic oral drugs were analyzed statistically in respect of minimum sales package unit and medication duration. RESULTS:There were 30 kinds of minimum sale package unit for 373 oral drugs,among which common capacity were 20,10,100 grain/tab-let/pill,accounting for 14.21%,14.21%,12.33% respectively,and 57.11% were used within 7 d. There were 13 kinds of mini-mum sale package unit for 57 oral drugs for lowering blood glucose,blood lipid and blood pressure,among which the common ca-pacity were 7,30,14,10 grain/tablet/pill,accounting for 33.34%,14.04%,14.04%,14.04% respectively,and 85.97% were used within 14 d,indicating sales package unit often based on weekly dosage. Among 6 kinds of type Ⅱ psychotropic oral drugs, minimum sales package unit capacity of 3 kinds were all 20 grain/tablet/pill,and those of other 3 kinds were 10,7,6 grain/tablet/pill;one of them were used more than 7 d. CONCLUSIONS:Minimum sales package unit is confirmed discretionarily. It is sug-gested that minimum sale package unit of oral drugs for lowering blood glucose,blood lipid and blood pressure should be packaged according to the dosage of 2 weeks to one nonth;the capacity of type Ⅱ psychotropic oral drugs is lower than the dosage of 7 days,and daily dose package is the best.

AIM:To observe the effect of Jingzhui Wentong (JZWT) Capsule (Ramulus Cinnamomi,Radix et Rhizoma clematidis,Radix Puerariae Lobatae,Radix Dipsaci,etc.) on somesthetic evoked potential (SEP),behavior and pathology of rat's cervical radiculitis induced by formalin. METHODS:Experiments were carried out:(1) 60 SD rats were divided randomly into 6 groups:control,model and Jingfukang groups,the high,moderate and low dose groups of JZWT Capsule. Rats of these groups were given water,Jingfukang or JZWT Capsule respectively,and SEP was tested after operation and 14 days after drugs were given to rats. At the same time,the animal behavior was observed daily. (2) 144 SD rats were divided into the same groups and given the same drugs as before. The nerve roots were taken out for pathological observation after 4,7,14,and 21 days with drug administration. RESULTS:In each drug group,the normal SEP was obviously restored,symptoms of encroached nerve were notably lightened,inflammatory reaction and proliferation tissue of mimic cervical radiculitis were more obviously alleviated than that in the model group of rat. CONCLUSION:JZWT Capsule can reduce significantly pathology change of mimic cervical radiculitis in rats,and promote the recovery of nerve function.

AIM: To study the allergic disease in recurrent tonsillitis. METHODS: Immunohistochemical technique was used to investigate interleukin-4(IL-4) production in tonsil. RESULTS:The result showed that: a higher incidence of IL-4 producing cells were found in the tonsils of all ages, and a high density of IL-4 was found in the reticular crypt epithelium and extrafollicular, but low density in germinalcenter. IL-4 has been shown play a crucial role in the pathogensis of allergic disease. CONCLUSION:Allergic disease is an important reason of recurrent tonsillitis. The conclusion will give a new way to cure recurrent tonsillitis.

Objective To detect the expression of E-cadherin and ?-catenin in breast carcinoma and analyze the relationship between E-cadherin and ?-catenin and the clinicopathological features. Methods The expression of E-cadherin and ?-catenin in breast cancer, paracarcinoma breast tissue, simple mastoplasia and atypical mastoplasia were detected by immunohistochemical method and the results were compared. Results The abnormal expression rates of E-cadherin and ?-catenin in breast cancer tissue were 51.9% and 61.1 %,respectively. Abnormal expression of E-cadherin was significantly correlated with histological grade. Abnormal expression of ?-catenin was significantly correlated with TNM staging, axillary lymph nodes metastasis and postoperative distant metastasis. COX multiple factor analysis showed that neither E-cadherin nor ?-catenin expression was an independent indicator for the prognosis of breast cancer. Conclusions Abnormal expressions of E-cadherin and ?-catenin are correlated with occurrence and development of breast carcinoma. Abnormal expressions of E-cadherin and ?-catenin are good indicators to judge invasion and metastasis of breast carcinoma.
