Objective To evaluate the influence of extraocular counterpulsation on ocular fundus blood vessels using high-frequency color Doppler ultrasonography. Methods Twenty-one patients with ischemic optic neuropathy were treated with extraocular counterpulsation. During treatment, the Doppler spectra were detected with high-frequency color Doppler ultrasonography. The peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance retinal index (RI) of central retinal artery and posterior ciliary artery were measured instantly before treatment and 1 min,5 min and 15 min after treatment. Results The instant PSV and EDV of central retinal artery and posterior ciliary artery were significantly increased (P＜0.05) after treatment, then decreased gradually. Fifteen min after treatment ,they returned to the level before treatment. Conclusions We can observe the changes of ocular fundus blood vessels noninvasively on high-frequency color Doppler ultrasonography. The method may be regarded as one of the basis for evaluating the effect of extraocular counterpulsation.

AIM:It is suggested that the peptidergic nerves containing substance P(SP),calcitonin gene-related peptide(CGRP),vasoactive intestinal peptide(VIP),neuropeptide Y(NPY) and tyrosine hydroxylase(TOH) co-exist in bone tissues and distribute in the active bone metabolism area,indicating these peptidergic nerves are closely related with bone growth and development. In this study,the expression of neuropeptides in tibial callus of rats after brain injury was observed. METHODS:The experiment was conducted in the Experimental Animal Center of Guangxi Medical University from February to May 2007. ①130 male Wistar rats of 3-4 months old and 450-550 g were randomly divided into fracture group(n =60),brain injury plus fracture group(n =60) and control group(n =10). ②The right parietal bone of anesthetized rats was exposed,and bone window of 5 mm was opened 2 mm near median line,then moderate brain injury was made by sap pressure,and the rat models of tibial fracture were established. The fracture group was only subjected to cranial bone window,and the control group was not given any treatment. ③The distribution of neuropeptide in tibia and callus succession as well as fracture healing were observed by HE and immunohistochemical staining on postoperatively days 3,7,14,21,28,and 35 days. The callus area in brain injury plus fracture group and fracture group was detected by computed radiography(CR) at 14,21 and 28 days after operation. RESULTS:All 130 rats were involved in the result analysis. ①At early stage after brain injury,there were a quantity of fibrous callus and cartilaginous callus formation in brain injury and fracture group and many neuropeptides immunoreactive nerve fibers in callus were found. Strong immunoreactivites of CGRP,SP,VIP,NPY,TOH occurred to osteogenitor cells and chondroblast,which proliferated in thickened endothecium. ②In brain injury and fracture group on day 14,the chondrocyte group was enlarged and subperiosteum chondrocyte layer was thickened;on day 21,bone trabecula was significantly thickened,and cartilage islands were increased;on day 28,there were still quantity of fibrous callus and cartilaginous callus,and sparse woven bones surrounding chondrocyte groups. In fracture group,periosteal reaction was slight,and fibrous callus was few;osteogenesis in bone and cartilage occurred,but mainly in bone. Moreover,the fracture healing was remarkably later than brain injury and fracture group. ③Callus area in brain injury and fracture group was larger than that in fracture group on days 14 and 21(P

Objective:To investigate the relationship between the plasminogen activator inhibitor 1(PAI 1) gene polymorphism and cerebrovascular disease and whether it played an important role in the pathogenesis of cerebrovascular disease Methods:The 4G/5G allele polymorphism in the PAI 1 gene promotor region were genotyped by polymerase chain reaction (PCR) from peripheral blood leukocytes from 60 normal controls, 65 patients with acute cerebral infarction and 31 hypertensives complicated with cerebral hemorrhage Their plasma PAI 1 activity were assayed by ELISA Results: The plasma PAI 1 activity level in the CI group was significantly higher than those in the other two groups PAI 1 level was significantly higher in 4G allele homozygous than both those in 4G/5G heterozygous and 5G homozygous Although PAI 1 level was higher in 4G/5G heterozygous than that in 5G homozygous, the difference had not reach statistically significant There were significant differences between acute cerebral infarction PAI 1 gene polymorphism and controls (P0 05), and PAI 1 levels of the 4G/4G genotype among female patients with CI were higher than those of the male patients with CI of the same genotype Conclusion: The results suggest that PAI 1 gene polymorphism may be a susceptible factor to acute cerebral infarction in Chinese, and 4G allele homozygous genotype may be the major risk factor of acute cerebral infarction, especially it may be an independent risk factor of female CI patients

ObjectiveTo evaluate combined pneumatic lithotripsy and vacuum suction during ureterorenoscopy.MethodsCombined pneumatic lithotripsy and vacuum suction during ureterorenoscopy was conducted for 52 cases of urolithiasis with the average age of the patients 36 years old.There were 3 cases of renal stone,9 upper ureteral stone,12 middle ureteral and 28 lower ureteral stone.The average surface area of the stones was 79 mm2.ResultsThe average operation time was 31 min and the fragmentation in situ 100.0%.The stone upward displacement rate was 1.7%.Fragmentation of the stone has been incomplete in 2 cases and ESWL was instituted.49 patients have been followed up for 1～3 months and the stone clearance rate was 96.0%.ConclusionsThe procedure would reduce the high instillation pressure which might cause upward displacement of the stone and liquid reflux to the renal parenchyma.The vacuum pressure set to -0.2～-0.4 bar is the most ideal.

[Objective] To evaluate the results of open reduction with bone autografting and calcaneus reconstruction with internal fixation in treatment of intra-articular calcaneus fracture. [Methods]From January 2005 to May 2007, 17 cases/19 feet of intra-articular calcaneus fractures received treatment of reconstruction plate and bone autografting, with 15 male/18 feet, 2 female/ 2 feet. Patients’ age ranged from 19 to 67 years (mean, 37.5 years). Fracture occurred in left side in 9 cases, right in 6 cases, both sides in 2 cases. All patients received treatment of open reduction with bone autografting and calcaneus reconstruction with internal fixation.[Results]All the patients achieved bone union. One stage union was achieved in 15 feet. Poor blood-supply was found in 3 feet and bone union was achieved after systematic treatment. Wound exudation was found in 1 feet, and bone union was achieved after dressing change treatment. All patients were followed up for an average of 19.7 months (10-38 months). The average union time was 2.5 months, without infection found.X-ray and CT were used to measure Bhler angle, width and axial length, all the indexed showed significant difference (P

Purpose:To explore the relationship between Epstein-Barr virus(EBV) infection and gastric carcinoma and the role of EBV lytic genes in the tumorigenesis of EBV-gastric carcinomas. Methods:185 gastric carcinoma tissues and 185 corresponding para-carcinoma tissues were tested for EBV genome by polymerase chain reaction (PCR)-southern analysis. EBV-encoded small RNA 1(EBER1) of the PCR positive specimens was detected by in situ hybridization (ISH). Gastric carcinoma with positive EBER1 signals was confirmed as EBV-positive gastric carcinoma. RT-PCR and Southern blotting were used to detect the expression of EBV lytic genes (immediately early genes BZLF1 and BRLF1, early genes BARF1 and BHRF1, late genes BcLF1 and BLLF1) in EBV-positive gastric carcinomas. Results:There were 13 EBV positive samples in gastric carcinomas (7.03%). No EBV positive sample was found from corresponding para-carcinomas. The difference of the EBV positivity was significant between carcinoma and corresponding adjacent carcinoma tissues(? 2= 11.0769,P=0.0009). In our series, age, pathological differentiation, clinical stages, lymph node metastasis and location of cancer were not different between EBV-positive and EBV-negative gastric carcinomas in (P=0.973, 0.141, 0.259, 0.586, 0.062, respectively), while sex was significantly different between EBV-positive and EBV-negative gastric carcinomas(? 2=5.2317,P=0.021). The EBV positivity of male was higher than that of female. Of the 13 EBV-associated samples, 7 exhibited BcLF1 transcript and 2 exhibited BHRF1 transcript. The transcripts of BZLF1 were detected in 6 cases, and those of BARF1 also in 6 cases. No BLLF1 and BRLF mRNA were detected in the 13 EBV-positive samples. Conclusions:EBV infection is associated with the development of gastric carcinoma. Lytic EBV infection occurs in part of the EBV-associated gastric carcinomas, and early genes BARF1 and BHRF1 may play an important role in the tumorigenesis of the EBV-positive gastric carcinoma.
