Objective: To prepare the conjugate of supcrantigen (SAg) staphylococcal enterotoxin A (SEA) and monoclonal antibody (McAb) against human hepatocellular carcinoma HAbl8 F(ab' )_(2) fragment and to investigate the anti-human hepatoma effect of peripheral blood mononuclear cells (PBMC) targeted by HAbl8 F(ab' )i-SEA. Methods: McAb HAbl8 was extracted and its F(ab' )_(2) fragment was prepared with papain; the conjugate HAblS F(ab' )_(2)-SEA was prepared with N-succinimidyl-3-(2-pyridyldithio) propionate (SPDP); eveny collected peak after purification was identified with gel chromatography; the activity of antibody in the conjugate was identified with immunohistocheinical ABC method; the anti-hepatoma effect of PBMC targeted by HAbl8 F(ab' )_(2)-SEA was observed with MTT method. Results: The conjugate HAbl8 F(ab' )_(2)-SEA was prepared successfully and it had obvious effect of targeting PBMC to kill hepatoma cells, and this effect is correlated positively with the dose of HAbl8 F(ab')_(2)-SEA. Control groups had no such effect. Conclusion: Targeting therapy of hepatoma with McAb-SAg conjugate might be a kind of hopeful model of hepatoma im-munotherapy.

[Objective] To retrospectively study and discuss the indications,surgical techniques and effect of treating hallux valgus with modified Austin operation-Chevron-Gerbert osteotomy or Chevron-Youngswick osteotomy.[Method]From October 1998 to April 2006,34 patients(62 feet)with hallux valgus were treated with modified Austin operation.The X-ray films of all patients were collected preoperatively,two weeks postoperatively and during the follow-up.The hallux valgus angle(HVA),intermetataral angle(IMA),proximal articular set angle(PASA)and distal articular set angle(DASA)were measured and analyzed on radiogram.[Result]All patients were followed up for 1-8 years(mean 3.6 years).HVA before and after surgery was 33.50??1.02?and 13.6??0.826 respectively.IMA was 16.0??0.837?before and 8.6??1.078 after surgery.AOFAS score was 44.8?5.7 before,and 87.6 4.2 after surgery.Significant difference was found between the results.According to AOFAS rating system,46 feets had a excellent result and 10 feet had a good result and the other 5 feet had a fair result.The rate of excellent or good results was 90.3%.[Conclusion]The modified Austin operation is a good,simple and reliable operation means for treatment of hallux valgus,which especially applies to severe hallux valgus with big PASA.The adductor hallucis or the sesamoid is not necessarily interfered in patients with slight or moderate hallux valgus.

The incidence of toileting problems is associated with the level of intellectual disability,and more common among the children with severe intellectual disability.This paper would review the classification,prevalence,consequences,origins of toileting problems,and also include the descriptions,assessment and practical considerations of behavioral interventions.

Objective To explore the effects of a microbubble agent (SonoVue) on radiofrequency ablation(RFA).Methods Twenty rabbits underwent RFA with or without SonoVue on two areas per rabbit liver.SonoVue were injected in bolus intravenously in 0.1 ml/kg.The morphology of hyperechogenic area were observed by conventional ultrasonography.The size of RFA lesions and ablation time were measured.The correlation was analyzed between hyperechogenic area and ablation size.Results Microbubbles didn't change the size of RFA lesions.However,with the addition of SonoVue to ablation,the morphology of hyperechogenic area was showed more regular and stable,and hyperechogenic area and ablation size were well correlated (r =0.849,P =0.000).Besides,the ablation time was much shorter (P ＜ 0.05).Conclusions The addition of SonoVue to ablation improve the prediction of ablated areas and reduce the ablation time,therefore it might be useful to prevent the unfavorable ablation of adjacent organs and vessels.

Otransplantation is a new subject which is developed so rapid that usually over the development of medical ethics.The shortage of organ supplement made organ transplantation face the challenge of medical ethics.Live organ donation has become a focal point of medical ethics in organ transplantation.It is necessary to eliminate all kinds of human organ commercialization and illegal transaction.We need pay more attention in the medical ethics issue about organ transplant,especially about live organ donation.Here is about the survey of medical ethics on live organ donation in People's Liberation Army No.181 Hospital.

Objective To compare the efficacy and safety of Etomidate-Dexmedetomidine and Propofol-Dexmedetomidine sedation in patients undergoing endoscopic radiofrequency ablation of gastroesophageal relfux disease (GERD).Methods Sixty adult patients, scheduled for elective endoluminal radiofrequency ablation for GERD under sedation were prospectively randomized into Etomidate-Dexmedetomidine (Group-E,n = 30) or Propofol-Dexmedetomidine (Group-P,n = 30) group. A bolus of 0.2 μg/kg of intravenous Dexmedetomidine was followed by intermittent Etomidate or Propofol injection during the procedure in order to maintain a proper depth of sedation with a Ramsay sedation scores of 5~6. Heart rates, mean blood pressure, oxygen saturation, respiratory rates and Ramsay sedation scores were recorded before sedation (T0), at the beginning of the examination (T1), during radiofrequency energy delivery (T2), at the time of gastroscopy (T3) and at the end of therapy (T4). Inter-group differences in sedation proifles (duration, time to recovery, incidence of body movement, Ramsay sedation scores and satisfaction of patient and endoscopist) and cardio-respiratory responses (heart rate, mean arterial pressure, oxygen saturation) were determined during and after radiofrequency ablation.Results No difference was found for therapy duration, anesthesia time or the time to recovery between Group-P and Group-E. Patients receiving Propofol experienced more bradycardia (Ρ = 0.032) and had higher incidences of vasoactives used (Ρ = 0.002) compared with that receiving Etomidate. Oxygen saturation in T1 (Ρ = 0.023) and T2 (Ρ = 0.009) was lower in the Group-P. No significant difference was found for other indicators.Conclusion Etomidate-Dexmedetomidine sedation was superior to Propofol-Dexmedetomidine sedation for GERD radiofrequency therapy with more stable cardio-respiratory responses.

Objective To invstigate the effect of high dose X-ray irradiation on the expression of multidrug resistance-1 (MDR1), Bcl-2, MMP7 genes. Methods A nasopharyngeal carcinoma cell line,CNE1, were irradiated with a total dose of 50 Gy. The resistance to the cisplatin of CNE1 cells and the irradiated CNE1 (CNE1 R) cells was detected by MTT. mRNAs expression of MDR1 , Bcl-2 and MMP7 was measured by quantitative RT-PCR. Results The expression of MDR1 increased in CNE1 R cells. The semiquantitative A value of MDR1 mRNA was 0.47 ±0.04, and the value of CNE1R cells (1st, 7th, 21st,28th, 35th, 42nd and 49th days after irradiation) were 0.67 ± 0. 06 (t = -5.44, P = 0. 003) ,0.70 ± 0. 01(t=-5.90,P=0. 002),0.73±0. 01(t= -6. 45,P=0. 001) ,0. 67 ± 0. 03 (t= -3.97,P=0.011),0.65 ±0.01(t = -4.43,P=0. 007),0. 62±0. 05(t= -2. 64,P=0.046) and 0.62 ±0.02(t = -3.34,P=0.021), respectively. Bcl-2 mRNA expression were 0.55 ±0.02 and 1.05 ±0.04(t = -9.93,P=0. 000) and MMP7 mRNA expression were 0.51 ±0.01 and 0.82 ±0.02(t = -8.51,P=0.000) in CNE1and CNE1 R cells. Conclusions The MDR1 expression was increased after a total dose of50 Gy irradiation,which may be related to the synchronous change of Bcl-2 and MMP7 genes.
