Objective To investigate the immune effect and the security after inoculating rabies vaccine in children. Methods To investigate and to detect the antibody level by the way of ELISA among the 337 children wounded by animals and vaccined the rabies vaccine. Results The positive rate of the antibody is 99.7%, the ad-verse effect is moderate. Conclusion Domestic adjuvant-free aqueous rabies vaccine, domestic freeze dried rabies vaccine and peregrinus freeze dried rabies vaccine all have satisfactory immunogenicity and little adverse effect.

Objective To investigate curative effects of endoscopic sternocleidomastoid muscle amputation for the treatment of congenital muscular torticollis.Methods A total of 23 children with congenital muscular torticollis were treated in this department.Their age was 1 month ~ 12 years old(median,30 months).A 5 mm trocar was inserted through the right axilla along the cleavage lines.Under the endoscopic visualization,the sarcolemma on the inferior portion of the muscle was bluntly dissected and a subcutaneous space was established by CO_2 inflation at the pressure of 6 mm Hg.Another two 3 mm incisions were made along the cleavage lines at lower lateral part of the neck and the anterior chest wall for the introduction of curved forceps and electric knife,respectively.The sternocleidomastoid muscle was transected with electrocautery and the external fascia within which the sternocleidomastoid muscle resides was also adequately divided. Results The operation was successfully completed under endoscope in all the 23 children.The mean operation time was 51.2 min(range,(35~)135 min) and the intraoperative blood loss was

Objective To study changes of?-glutamyltransferase(GGT)and its isoenzyme in urine and renal cortex of rats with subacute cadmium exposure.Methods Sixty healthy SD male rats were chosen and divided randomly into control group,middle dose group and high dose group,which were orally dosed daily with feed containing0,5and10mg cadmium per kg for six weeks.The activities of GGT and its isoenzyme in urine and renal cortex of the rats were determined in the3rd and6th week respectively.Re sults During the whole experimental period,the body weights and kidney to body weight ratios of control group,middle dose group and high dose group showed no significant differences.The GGT activities of middle dose group and high dose group increased significantly with the prolongation of exposure to cadmium and the increase of cumulative exposure compared with those in the control group.Unusual bands of GGT isoenzyme in the urine and renal cortex homogenate were found in the3rd week and the incidence of unusual bands of GGT isoenzyme was100percent in the6th week in the cadmium-treated rats of middle dose group and high dose group.Con clusion The GGT activities and the unusual bands of GGT isoen-zymes in the urine and renal cortex could be used as sensitive indexes to identify the renal toxic effects induced by cadmium.

The experimental right cerebral contusion model was established in rats.To observe the relationship between the expression of Nitric oxide synthase 1(NOS1)and time elapsed after cerebral contusion,the expression of Nitric oxide synthase 1(NOS1)and mRNA was studied by immunohistochemistry and in situ hybridization at different intervals after cerebral injury.The results indicated that a positive relationship existed between the expression of NOS1 and NOS1 mRNA and the intervals elapsed after brain injury.This method also can be used to distinguish antemortem and postmortem injury rat′s cerebral contusion.So that,the expression of NOS1 and NOS1 mRNA is of great value for timing of brain injury.

Objective To determine the risk factors of Contrast-induced Nephropathy(CIN)and discuss means of minimizing the risk or preventing this complication.Methods A retrospective analysis of the data of 17 patients who were confirmed CIN in The Second Affiliated Hospital of Guzngzhou Medical College from 2004.6-2005.12 was admin- istrated.The contrast medium was lopamidol,doses varied from 70 mL to 150 mL.Serum creatinine(Scr)was meas- ured before and day 2,day 7 after angiography.Results Scr elevation of all the patients was 82.35?99.10?mol/Lat day 2.Scr of 11 patients returned to normal at day 7(103.82?20.49)?mol/L,the other 6 still remain high level (437.83?335.85)?mol/L and 3 of them needed hemodialysis therapy.Conclusion Risk factors of CIN include baseline Scr elevation,congestive heart failure,diabetes,high doses of contrast medium and concomitant use of nephro- toxic drugs.Contrast medium should be used at the minimal dose necessary in patients preexisting renal impairment.Di- uretics and other nephrotoxic drugs should be withheld for at least 24 hours before and after exposure to contrast medium. Additional fluids and hemofiltration should be given to prevent CIN.

Objective To determine the possible differences in DNA methylation of benign and malignant thyroid tumors and its role in tumorgenesis and tumor progression. Methods Infinium human methylation 450 bead chip platform was utilized to screen the whole-genome of benign and malignant thyroid tumor tissues surgically removed from a patient for the determination of their DNA methylation levels. The genes with significant differences in methylation were analyzed for their functional pathways with bioinformatics. Results There were significant differences in DNA methylation between benign and malignant thyroid tumor. The inflammation-related pathways, such as T cell, Jak-STAT and cytokine-cytokine receptor signaling pathways involved in the biological process of tumorgenesis and tumor progression. Conclusions The differences in DNA methylation between benign and malignant reveal a close relationship between inflammation and tumorgenesis and tumor progression and provide a novel method for investigation of thyroid cancer development and target drug discovery.

Objective To evaluate the patency rate of two types of metallic biliary stent in treating malignant biliary stenosis, and to discuss the patient’s survival rate. Methods A total of 126 patients with malignant biliary stenosis were treated with percutaneous implantation of biliary stent. The clinical data were retrospectively analyzed. A total of 167 metallic biliary stents were used in 126 patients. Ninety - two metal stents of mesh type were employed in 70 cases, while 75 metal stents of laser engraving type were adopted in 56 cases. After the treatment all patients were followed up, and the stent patency time as well as the median survival time was determined. The results were analyzed and compared between the two types of stents. Results Technical success rate was 100% (126/126). The median patency rate time of mesh type and laser type was 182 days and 196 days respectively, the patient’s median survival time of mesh type group and laser type group was 179 days and 186 days respectively. No statistically significant differences in the stent patency time and in the median survival time existed between the two groups (P > 0.05). Conclusion In treating malignant biliary obstruction with stenting, the mesh type stent and the laser type stent have quite same therapeutic effect. Therefore, in clinical practice the two types of stent can be replaced with each other to a certain degree.
