0.05),but there were the significant difference of prognosis in point and sheet bleeding groups,internal carotid artery system group with hemorrhage,multiple site bleeding group compared with that of cerebral infarction group(all P0.05).Conclusion The correlation factors of impact on HT after cerebral infarction mainly have the volume of blood and bleeding part.

Thyroglossal duct cyst is the most common congenital malformation of the neck. It is generally with non-specific symptoms. In our hospital, one case of laryngeal obstruction caused by giant thyroglossal duct cyst was cured, and this case was reported for reference.

A simple and effective method for the duplex PCR detection was developed by using sequences of exogenous gene(RDV MP-)and endogenous gene(Zein)as templates for PCR amplification.The results of routine PCR amplification for RDV MP-gene in transgenic maize suggested that RDV MP-gene can stably inheritate in transgenic plants and their progenies;The duplex PCR detection of all negative and part positive samples that obtained by routine PCR amplification confirmed that above negative results were exact,also showed that the quality of extracted DNA can meet the need of PCR amplification.The error ratio of negative samples was 1.4%.The method used in this study was simple and credible and can be used to detect transgenic plants and their products.

· AIM: To investigate the complications of intravitreal triamsinolone acetonide (TA) injection in vitrectomy for proliferative diabetic retinopathy (PDR).· METHODS: From February 2005 to January 2007, 18patients (18 eyes) with PDR who were injected with TA in vitrectomy were observed retrospectively after surgery.· RESULTS: During a postoperative follow-up period of 3 to 6 months (mean 4.6 months), some complications including deposit of TA granules on the macular region and surface of the retina (3 eyes), postoperative vitreous hemorrhage (3eyes), elevated intraocular pressure (2 eyes) and pseudohypopyon (1 eye)were observed.· CONCLUSION: The complications after surgery such as deposit of TA granules on the macular region and surface of the retina and pseudohypopyon could be cured without any special treatment. All eyes with elevated intraocular pressure after surgery were controlled by drug. Re-operation may be an effective method for patients with unabsorbable vitreous hemorrhage after vitrectomy.

Objective To investigate whether emodin enhances chemosensitivity of pancreatic cancer cells and the mechanism. Methods Normal human skin fibroblasts and pancreatic BXPC-3 cells were divided into control group, cisplatin (5 mg/L) treatment group, gemcitabine (0.5 μmol/L) treatment group, emodin (50 μmol/L)+ cisplatin (5 mg/L) co-treatment group and emodin (50 μmol/L) + gemcitabine (0.5 μmol/L) co-treatmentgroup. The cell viability was detected by MTT assay, the cell apoptosis rate by flow cytometry, the expression of the multidrug resistance-associated protein 1 ( MRP1 ), MRP2, breast cancer resistance protein (BCRP) and P-glycoprotein (P-gp) mRNA in different cell lines was determined by reverse transcription polymerase chain reaction.All data were analyzed using the t test. Results The cell viability and apoptosis rate of pancreatic BXPC-3 cells after treatment were 62.44% ± 3.42% and 27. 10% ± 4.24% in the cisplatin treatment group, and they were 30.53% ±0.05% and 66.33% ±9.37% in the emodin + cisplatin co-treatment group. There were significant differences in cell viability and apoptosis rate between the two groups (t = 13.20, 5. 35, P < 0.05 ). The cell viability and apoptosis rate of pancreatic BXPC-3 cells after treatment were 79.82% ±2.83% and 13.48% ± 1.65%in the gemcitabine treatment group, and they were 45.65% ± 2.46% and 62.74% ± 10. 18% in the emodin +gemcitabine co-treatment group. There were significant differences in cell viability and apoptosis rate between the two groups (t = 12.89, 8.28, P < 0. 05 ). There was no significant difference in the viability of normal human skin fibroblasts between the cisplatin treatment group and the emodin + cisplatin co-treatment group, and also between the gemcitabine treatment group and the emodin + gemcitabine co-treatment group (t = 2. 08, 0. 64, P >0.05 ). Expression of MRP1 mRNA was detected in pancreatic BXPC-3 cells, whereas the expression of MRP2,BCRP and P-gp mRNA was undetectable. The expression of MRP1 mRNA in pancreatic BXPC-3 cells was significantly down-regulated in the cisplatin treatment group, and cisplatin + emodin co-treatment had an additive effect on down-regulating the expression of MRP1 mRNA. Conclusion Emodin may enhance chemosensitivity of pancreatic cancer cells to cisplatin by down-regulating the expression of MRP1 mRNA.

Objective To analyze the relationship between the clinical features and the dysfunction and derangement of knee osteoarthritis(OA),in order to improve the understanding of knee OA.Methods Clinical data including symptoms,physical signs,X-ray,arthroscopical findings,pathologic changes,preopera-tive and postoperative diagnosis,treatment and curative effects from206post-arthroscopy patients with OA were analyzed retrospectively.Results The common physical signs were tenderness in knee,positive grinding test of patella,McMurray sign,fricative,muscular atrophy of quadriceps femoris,and stretch or flexion limita-tion.X-ray abnormalities were found as follows in decreasing freguency:bony hyperplasia,articular facet sclero-sis,osteoporosis,uneven articular surface,narrowing of joint space and loose bodies.Arthroscopical findings were as follows:synovial congestion and proliferation,hypertrophy or entrapment of fat pad,osteophyte,syn-ovial fold entrapment,stripping of cartilage,meniscal lesions,subchondral bone exposure,anterior cruciate lig-ament friction or obstruction,and loose bodies.The common diseases that liable to misdiagnosis preoperatively were synovial chondroma,anterior cruciate ligament impingement syndrome and meniscal lesions.The rate of excellent and good results after arthroscopic treatment was86.6%.Conclusion Hypertrophy and entrapment of fat pad,thickening and entrapment of synovial fold,stripping of cartilage,meniscal lesions,anterior cruciate ligament friction or obstruction,and loose bodies are the key factors that cause knee dysfunction in OA.The arthroscopic treatment is an effective supplement in treating knee OA.

【Objective】To observe the regulation of acupuncture on experimental insulin resistance in rats and to investigate the influence of diet during the acupuncturing.【Methods】Forty rats were equally randomized into blank group,model 1 group,model 2 group,acupuncture 1 group and acupuncture 2 group.Rat models with insulin resistance were induced by feeding forage of high fat,sugar and salt.After the models were induced successfully,blank group was still fed with normal forage,model 1 group still with forage of high fat,sugar and salt,model 2 group with normal forage instead,acupuncture 1 group still with forage of high fat,sugar and salt for 2 weeks and acupuncture 2 group with normal forage instead.Meanwhile,acupuncture 1 and 2 groups received acupuncture once a day.The changes of fasting plasma glucose(FPG),plasma insulin(INS),insulin sensitivity index(ISI),serum Cpeptide(C-P) and the ratio of INS and C-P were observed after treatment.【Results】FPG,INS,C-P and INS/C-P were increased and ISI decreased in model 1 group as compared with the blank group(P

Objective To evaluate the role of comprehensive cardiac MRI (CMRI) in diagnosis of patients with coronary artery disease (CAD) Methods 55 patients with acute coronary syndrome underwent MR imaging 3-6 months after the reperfusion therapy Short axis images acquired by cine FIESTA sequence were used to analyze the motion of the different anatomy regions Used the FGRE ET sequence to detect the patterns of the first pass perfusion after injection of 0 2 mmol?kg 1 Gd DTPA at a flow of 3 ml?s 1 7-12 min later, MDE pulse sequence used to recognize the high signal in the myocardium Results At study entry, 38 subjects had the defect in the first pass perfusion The signal in the defect was significantly lower than that in the normal regions, which always in the subendocardium 51 subjects had delayed enhancement regions in the myocardium at different degree and different range The mean intensity of hyperenhanced regions was 4 36 times higher compared with that of the regions without hyperenhancement The difference between the 2 regions had statistical significance The extent of hyperenhancement was significantly related to the abnormality of wall motion The range of delayed enhancement was bigger than that of the first perfusion defect Conclusion Comprehensive evidence of delayed hyperenhancement, dysfunction of myocardium, and the defect of first pass perfusion can be used to predict myocardial infarction
