Objective To explore the mechanism of tripterygium wilfordii hook f(TWHF)for Henoch-Schonlein purpura nephritis(HSPN,nephrotic type)in children.Methods All the children with HSPN(nephrotic type)were divided into 3 groups casually.Method of radioactive pairs conjugating analysis was used to determine the numbers of glucocorticoid(GC)receptors(GCRs).Results were statistically analysed respectively.Results GCRs tested in all the patients with HSPN(nephrotic type)before treatment were statistically lower than those in control group of normal children;GCRs in all the patients tested after 1 week treatment with GC were lower than before treatment.Three weeks later,GCRs in patients treated with TWHF increased much higher than them without TWHF.Following up the recurring times of all the patients 3 months to 5 years,they were much more in patients treated without TWHF treatment than in patients treated with it.Conclusions TWHF treatment on HSPN(nephrotic type)is obviously effective.It can not only decrease the dosage of GC,but decrease the recurring times.One of the mechanism may be TWHF can resist the down-regulation GC to GCR,and enhance the effect of GC.

OBJECTIVEThe purpose of the study was to investigate the content of nickel (Ni) ion in patients' saliva after wearing the porcelain-fused-to nickel-chromium (Ni-Cr) crown or the porcelain-fused-to nickel-chromium-titanium(Ni-Cr-Ti) crown.

METHODS50 patients who had one molar or premolar needed repairing were selected and divided into two groups randomly. Patients in one group were fabricated with porcelain-fused-to Ni-Cr crown and the patients in the other group were fabricated with porcelain-fused-to Ni-Cr-Ti crown. Collect the patients' saliva before wearing, 1 week, 3 months, and 6 months after wearing. The content of Ni ion in saliva was detected by inductively coupled plasma mass spectrometry (ICP-MS).

RESULTSThe content of Ni ion in both groups increased at the first week, and go back after 6 months. There were no significant differences before wearing, 1 week, 3 months, and 6 months after wearing. There were no significant differences between the two groups.

CONCLUSIONWearing the porcelain-fused-to Ni-Cr crown or the porcelain-fused-to Ni-Cr-Ti crown has no significant influence on the content of Ni ion in saliva.

OBJECTIVETo evaluate the effect of the platelet-derived growth factor-BB (PDGF-BB) on the phenotypic transformation of corpus cavernosum smooth muscle cells (CCSMC) in SD rats.

METHODSCCSMCs were primarily cultured in the modified tissue sticking medium and subjected to immunofluorescence assay. The cells were divided into a blank control and four PDGF-BB groups, the latter exposed to 5, 10, 20, and 40 ng/ml of PDGF-BB, respectively, for 24 hours, and the cells in the 20 ng/ml PDGF-BB group treated for 24, 48, and 72 hours. The the relative expressions of α-SMA, SMMHC, calponin, and OPN mRNA were determined by real-time fluorescence quantitative RT-PCR (qRT-PCR).

RESULTSThe α-SMA positive rate of the CCSMCs was over 95%. Compared with the blank control group, the expression levels of α-SMA, SMMHC, and calponin mRNA were significantly decreased (P < 0.05) while that of OPN mRNA remarkably increased (P < 0.05) in the PDGF-BB groups. The 20 ng/ml PDGF-BB group also showed significantly downregulated expressions of α-SMA, SMMHC, and calponin mRNA (P < 0.05) and upregulated expression of OPN mRNA (P < 0.05) at 24, 48, and 72 hours.

CONCLUSIONPDGF-BB can induce the transformation of the phenotype of CCSMCs in SD rats from the contractile to the synthetic type.

BACKGROUND: This study was designed to describe the current tends of emergency tracheal intubation and predict difficult airway intubations in emergency department (ED) at a teaching hospital in Korea. METHODS: All patients who was taken endotracheal incubation in ED during a 1-year period (Mar 1997 through Feb 1998) were included in the study population. Medical records of the patients were retrospectively reviewed. Among them, 56 patients were prospectively evaluated parameters to predict difficult airway intubations. RESULTS: During the study period, a total of 413 patients(1.5%) required endotracheal intubation. Except far 2 cases, all patients intubated orotracheally, and 298(72%) patients were intubated by emergency medicine resident. Pharmacologic adjuncts were used in 200(48%) patients, the neuromuscular blocking agent(NMBA) was used in 16(3.8%) Commonly used drugs were thiopental and vecuronium. The difficult incubation was not associated with presence of denture, length and circumference of neck, and mental status. The visibility of vocal cord on laryngoscopy significantly correlated to the difficult airway. CONCLUSION: At this institution, the majority of ED incubation were performed by emergency physicians and NMBA was not routinely used. The visibility of vocal cord during the direct laryngoscopy could be a predictor of difficult incubation in ED.

In vivo tumor imaging technique method based on bioluminescence principle was established to evaluate the anti-tumor effect of paclitaxel mixed micelle (PMM). MDA-MB-231 tumor cells with luciferase reporter vectors were firstly implanted into nude mice, and subsequently the luciferase substrate was regularly injected during intraperitoneal administration of PMM. Then the tumor size, growth and the intensity of light signals were monitored with in vivo imaging technique. The method of luciferase tumor in vivo imaging could be real-time, reliable and exact in labeling and reflecting the growth of tumors, and the observed results were consistent with that by conventional method, so it would be a feasible approach to study anti-tumor effect of drugs. The anti-tumor effect of paclitaxel mixed micelle was observed by this method, and the results showed that this formulation could inhibit growth of tumor, and the anti-tumor rate of it was about 85%.

Objective To investigate the ecological habit and characteristics of Trichobilharzia cercariae in the Huaihe river system. Methods During June of 2002-May of 2003, Radix auricularia snails were collected monthly in Yaohe Fishery of the branch of the Huaihe River. The cercariae, released from the positive snails and collected by Shade Drop Bottle, were examined by direct press. Ducklings were infected by cercariae with different ages and examined for the infection by miracidia hatching method.Results The results showed a typical seasonal fluctuation in infection rate of the snails, i.e. the cercariae detection rate was 0.81% in July, 0.65% in June, 0.07%-0.26% in April, May, August, September and October respectively, with a significant difference (? 2=26.73, P

Objectiye To investigate the value of liver transplantation for the treatment of end-stage hepatic alveolar echinococcosis(HAE).Methods The clinical data of 8 patients with end-stage HAE who received liver transplantation at the First Affiliated Hospital of Xinjiang Medical University from December 2000 to August 2010 were retrospectively analyzed.The operation time,anhepatic phase,infusion of suspension of red blood cells and postoperative complications were observed.Results The median operation time,anhepatic phase and infusion of suspension of red blood cells were 635 minutes(range,490-760 minutes),66 minutes(range,44-240 minutes)and 20 U(range,4-40 U).Liver transplantation was successfully carried out on 7 patients except for 1 patient who received emergent liver transplantation died of severe hepatic encephalopathy,renal failure and coagulation disorder on postoperative day 1.The median follow-up time was 6 months(range,3-29 months).One patient died of septicopyemia in postoperative month 3,1 died of incurable infection of bile duct in postoperative month 5,and 1 died of acute rejection in postoperative month 6.One patient was complicated with stricture of the bile duct anastomosis,and was cured by choledochojejunostomy.The size of the metastatic lesion in the left lung of 1 patient was reduced.One patient who underwent liver autotransplantation had no signs of residual liver disease with good liver function.Conclusion End-stage HAE is an indication for liver transplantation.A minimum dose of immunosuppressive agent and systemic administration of anti-HAE drugs are necessary to prevent the recurrence of HAE and ensure a long-term survival.Liver autotransplantation is the optimal method for the treatment of end-stage HAE,because no immunosuppressive agent is needed after operation.
