Objective To study the clinical result of the surgical treatment of upper cervical vertebra disease from high anterior cervical retropharyngeal approach.Methods Among 14 patients,there were 7 C_(2.3)disc hernia- rions combined with C_(2.3)dislocations,3 Hangman fractures,2 odontoid process fractures and 2 C_3 tumors.All patients underwent the high anterior cervical retropharyngeal approach.10 cases were given discectomy of C_(2.3)or focus clear- ance of C_3,iliac bone autograft or titanium cage filled and internal fixation with titanium plate.2 cases of odontoid process fractures were given anterior screw fixation.Results 14 cases got successful exposure.The decompression, reduction,lesion clearance and fusion with internal fixation were done in all patients.There were no important vascu- lar or nerve injuries.The surgical treatment could improve the spinal cord nerve function to a certain degree for the cases with compression of spinal cord.Conclusion Good exposure of upper cervical spine and effective surgical oper- ation could be achieved from high anterior cervical retropharyngeal approach,with minimal trauma and complication, and it was a favorable approach.

OBJECTIVETo study the effect of Shuangling Fuzheng anti-tumor preparation (SLAP) five groups on proliferation and c-myc gene expression of SGC-7901 cells in vitro.

METHODThe inhibitory effect of single SLAP (40 -640 microg x mL(-1)) and combined therapy with adriamycin (0.4, 4.0 microg x mL(-1) or cisplatin (0.1,1.0 microg x mL(-1) on human gastric carcinoma SGC-7901 cells proliferation were observed by MTT colorimetric analysis method. Technique of flow cytometry in vitro was used to measure the rate of positive sign of SLAP (80 - 320 microg x mL(-1)) on c-myc gene protein of SGC-7901 cells.

RESULTSGC-7901 cells proliferation were inhibited by single SLAP in dose of 40 - 640 microg x mL(-1) 24 h. Its inhibitory rate was increased with increase of dose. The inhibitory rate on SGC-7901 cells could be increased by SLAP in dose of 40 - 640 microg x mL(-1) plus adriamycin in dose of 0.4 and 4.0 microg x mL(-1) or plus cisplatin in dose of 0.1 and 1.0 microg x mL(-1). At the same time, SLAP (80 - 320 microg x mL(-1)) also could inhibite the expression of c-myc gene of SGC -7901 cells.

CONCLUSIONSingle SLAP had inhibiting effect on human gastric carcinoma cells proliferation with a dose-effect relationship and synergic effect while combined with adriamycin or cisplatin. To inhibit the expression of c-myc gene of human gastric carcinoma cells might be one of action mechanisms of SLAP, which inhibited tumor cells proliferation.

Objective To summarize the clinical characteristics,diagnosis and treatment of malignant tumor after renal transplantation.Methods The clinical data of 2106 renal transplants in 1945 patients undertaken in our hospital from September 1978 to December 2009 was retrospectively studied.Results Of these 1945 patients, 39 cases were diagnosed as having malignant tumor (incidence: 2.0 ％).The interval between transplantation and clinical diagnosis ranged from 8 to 124 months with a median of 57.0 months.Among the 39 cases of malignancy, there were 22 urinary system carcinomas, 8 digestive system carcinomas,2 lung cancers,2 breast cancers,2 lymphomas,1 dura small cell carcinoma,1 pleura poorly differentiated carcinoma and 1 metastatic carcinoma of liver with unknown primary tumor. Surgery was conducted in 28 patients,of which 16 were survived but the other 12 patients died of metastasis ranged from 3 months to 96 months (median,33 months) after operation.11 cases without operation died within from 3 d to 36 months (median,5 months) after diagnosis.Conclusions The incidence of malignant tumors in renal transplant recipients increased markedly.The most common type of the malignant tumors is urinary system carcinoma.The key measure of success in treating malignancy after renal transplantation is early diagnosis and surgical resection.

AlM: To examine the retinal nerve fiber layer ( RNFL ) changes in early primary open angle glaucoma ( POAG ) by comparing the superior half of the optic disc with the inferior disc half.METHODS: lt was a clinical observational study. The study included 30 patients ( 39 eyes ) with POAG and 20 normal subjects ( 40 eyes ) . Visual field was tested by Zeiss Humphrey750 and the optic disc topographic parameters and RNFL thickness were measured by Zeiss Cirru HD-OCT. Collecting information included visual field mean defect ( MD ) , glaucoma hemifield test ( GHT ) , intraocular pressure ( lOP ) , C/D ratio and RNFL thickness. Data were analyzed by statistic software SPSS18. 0. The differences between two groups were assessed using t test.RESULTS: The differences of superior RNFL minus inferior RNFL thichness on the corresponding clock-hour locations were caculated in two groups. There was a significant difference in superonasal- inferonasal RNFL thickness between two groups (t=2. 526, P=0. 014), and there were no significant differences in the others ( all P>0. 05).CONCLUSlON: The asymmetry of optic disc hemifield RNFL is found in early primary open angle glaucoma patients. The superonasal RNFL ( 1 o’clock for right eye, and 11 o’clock for left eye ) is more fragile to loss than inferonasal RNFL (5 o’clock for right eye, and 7 o’clock for left eye) .

Objective To study the efficacy and safety of CO2 laser microsurgery for early glottis carcinoma.Methods The data of 96 cases of early glottic laryngeal carcinoma treated with CO2 laser microsurgery were retrospectively analyzed.Surgical specimens were conventionally embedded with paraffin and serially sectioned.Sections were stained by using hematoxylin-eosin for pathologic examination.The local control rate was observed after operation.Results Among the 96 specimens,88 surgical margins were negative and 8 were positive.10 patients (10.4 ％) recurrenced followed up for 3 years.The recurrence rates of Tis,T1a,T1b and T2 were 0 (0/10),4.1％ (2/48),25.0 ％ (4/16) and 18.1％ (4/22),respectively,with significant differences among groups (X2 =6.105,P ＜ 0.05).All of 8 cases with positive margin and 2 cases with negative margin were recurrened.The recurrent rate of patients with involvement of the anterior commissure was 30.0 ％ (6/20),which was higher than that of patients with no tumor invasion [5.3 ％ (4/76)] (X2 =9.624,P ＜ 0.01).Conclusions The safe edges can be obtained by CO2 laser microsurgery for early stage of glottis carcinoma,which have advantages in local control rate,vocal function of the larynx and curative effect.

Objective To evaluate the feasibility of composite material of bone morphogenetic protein (BMP) and PLGA/TCP in repair of peri-porous-titanium bone defects in adult rabbits.Meth- otis The composite of PLGA/TCP scaffold with bovine BMP was made and implanted in distal bone de- fects peri-porous-titanium in femur of adult rabbits.The effect of BMP with PLGA/TCP on peri-prosthesis was evaluated by means of scanning electron microscope (SEM),energy dispersive X-ray analysis (EDX) and biomechanics.Results BMP with PLGA/TCP showed obvious peak of Ca and P of EDX in the pores of titanium in experiment group six weeks after operation and higher than that in control group (P＜0.05).Push-out test demonstrated that the bonding strength between the composite of HA coating/ porous titanium and bone was increased significantly with time (P＜0.05).In experiment group,at 6 and 12 weeks,peri-porous-titanium had higher shearing force compared with control group (P＜0.05). Conclusion BMP loaded with PLGA/TCP is a promising bone graft for bone defects in revision arthro- plasty,as indicates that bone induction of BMP plays an important role in biological stabilizaiton.

Objective To investigate the effect of problem based learning (PBL) applied in the course of Assessment & Evaluation of Physical Therapy. Methods PBL and traditional teaching were applied in different classes. Their scores of the final examination were compared, and the students were investigated with the questionnaire. Results The scores of final examination were higher in the PBL class than that in the traditional teaching (P<0.001). A lot of the students accepted the PBL in the course. Conclusion PBL can improved the teaching quality of the course of Assessment & Evaluation of Physical Therapy.
