The sera of 40 normal controls,61 cases of various malignant diseases except pancreatic cancer,53 cases of various henign diseases,and 33 cases of pancreatic cancer were examined with ELISA to determine the serum level of pancreatic cancer-associated antigen(PCAAc).Its normal value was 12.59?6.34 mg/L(x?s),and the value was 57.25?82.93 mg/L in the pancreatic cancer group,which was significantly higher than the normal value and that of the other malignant disease group(P

? AlM: To analyze the incidence, characteristics and related risk factors of high intraocular pressure after pars plana vitrectomy ( PPV) .
?METHODS: Totally, 146 patients (146 eyes) undergone PPV in our hospital were selected. Age, gender, eye, course and operation time of patients were compared, in order to understand the incidence rate and characteristics of high intraocular pressure. Primary diseases, intraoperative treatment methods and intraocular tamponade type were compare, in order to analyze the related risk factors of high intraocular pressure.
? RESULTS: Forty - seven patients occurred high intraocular pressure after operation, the incidence rate was 32. 2%. There was no significant difference in age, gender, eye, course and operation time (P>0. 05). The incidence rate in diabetic patients with simple vitreous hemorrhage and with tractional retinal detachment were 21.1% and 57.6%, respectively (P<0.05). The incidence rate in retinal detachment with PVR below grade C2 and above C2 were 19. 0% and 43. 8%, respectively (P<0. 05). The incidence rate in ocular trauma with vitreous hemorrhage and with intraocular foreign bodies were 25. 0% and 70. 0%, respectively (P<0. 05). The incidence rate of patients treated with panretinal photocoagulation was 50. 8%, significantly higher than patients without treated with panretinal photocoagulation (P<0. 05). The incidence rate of patients treated with part panretinal photocoagulation was 29. 5%, higher than patients without treated with panretinal photocoagulation, but there was no statistical difference ( P > 0. 05 ). The incidence rate of using silicone oil, C3 F8 and simple ventilation were 59. 7%, 34. 5% and 14. 5%, respectively (P<0. 05).
? CONCLUSlON: After vitrectomy intraocular hypertension incidence and preoperative, intraoperative treatment of primary disease is closely related to factors such as the way and intraocular tamponade.

Objective To study the influence of interleukin-11 (IL-11) on graft versus host disease(GVHD) and graft versus leukemia(GVL) after allogenic bone marrow transplantation and related mechanism in acute lymphoblastic leukemic(ALL) junior mice.Methods The impact of IL-11 on CD4 and CD8 T cell after transplantation was evaluated by flow cytometry;it was observed that the GVHD pathology chance of internal after transplatation in ALL junior mice;the survial time after transplantantion was recorded;the level of tumor necrosis factor-?(TNF-?) which evidently related to GVHD was evaluated by ELISA.Results IL-11 could decrease the quantity of CD4 T cell and increase CD8 T cell;IL-11 could obviously increase the survival time and decrease the level of TNF-?. After ALL junior mice transplatated,IL-11 could delay and relieve GVHD.Conclusion IL-11 can alleviate GVHD and retain the effect of GVL after allogenic bone marrow transplantation.

Objective To explore the personality characteristics of abused children in order to reduce the incidence of child abuse.Methods Two hundred and ninty five middle school students were investigated with general questionnaire and Eysenck Personality Questionnaire of children. Eighty six students experiencing child abuse (CA) last year as study group and one hundred and ninety six non-abuse children as controls (NCA) were analyzed by means of Eysenck Personality Questionnaire of children.Results The score of neuroticism in CA group was significantly higher than that in the control group (55.62±10.60/52.65±10.98,t=-2.114 P=0.035). The score of lie in CA group was significantly lower than that in control group (42.21±9.87/46.04±9.20,t=3.184 P=0.002). On the impact of different sex, the psychoticism score of male was significantly higher than that in the control group(52.37±11.49/48.04±9.97,t=-2.227 P=0.028), and the lie score was significantly lower than that in control group(41.03±9.18/46.18±8.79,t=3.125 P=0.002).The scores of those in the female were not significant.Conclusions There is a close association between the unstable emotion and child abuse in children, so training emotional self-control and emotional expression of children might be a intervention strategy in the future. In addition, the frequency of lie in children is probably one of factors that determine whether children are abused or not.

Objective To evaluate the efficacy of port catheter system(PCS)placement in pulmonary artery via percutaneous subclavicle vein treatment for multiple metastatic tumor in the two lungs and discuss the PCS technique.Methods Fifteen multiple metastatic tumor patients(13 hepatocellular carcinomas,one mandible grand adenocarcinoma,one oral bottom squamous carcinoma)were carried out with pulmonary artery PCS placement by way of percutaneous subclavicle vein.FPA/FPM/GP chemotherapy scheme were introduced every 4～6 weeks.Results The success rate of PCS placement technique was 93.3%(14/15).One case failed.Percutaneous subclavicle veins were performed 14 cases in right side and 1 in left one.Following up 2～43 months,2～7 chemotherapy cycles(mean 5 cycles)were accomplished,and the clinical CR and PR were achieved in 1 and 3 cases respectively with clinical efficacy rate 28.6%(4/14).Major side reaction was late wound healing in 1 case.Conclusion PCS placement in pulmonary artery treatment for multiple metastatic tumor in the two lungs is effective,and mastering operation technique is the key for increasing operation suc- cess rate.

A strain of Cellulosimicrobium cellulans Ha8 was studied on its morphological, biological characteristics and its utilization of several kinds of benzoic compounds, the results showed this strain was Gram-positive, the long rod-shaped cells were changed into short rod-shape gradually. pH value from pH 6.0 to pH 9.0 and the temperature from 20 ℃ to 40 ℃ were good for its growth. It could not only hydrolyze protein and starch, use cellulose and pectin, decomposite chitin, liquify gelatin and fix nitrogen, but also use phenol, xylene, benzoic, cinnamic acids and diphenlamine as the sole carbon resource for its growth. It could tolerate 0 mmol/L~30 mmol/L, 0 mmol/L~8 mmol/L, 0 mmol/L~30 mmol/L, 0 mmol/L~15 mmol/L and 0 mmol/L ~ 40 mmol/L of benzoic acids, phenol, xylene, cinnamic acids and diphenlamine seperately, but could not use 2,4-dinitrophenol, o-Nitrophenol, 2-Methoxyphenol, aminobenzenesulfonic acid, catechol and o-Phenanthroline as its sole carbon resource.

AlM: To observe the clinic effect of oral mucosa transplantation in the treatment of severe contracted conjunctival sac after ocular prosthesis implantation .
METHODS: Thirty-three cases ( 33 eyes ) with globe disorders and severe contracted conjunctval sac were operated ocular prosthesis implantation firstly, and conjunctival sac plasty using oral mucosa after 6mo.
RESULTS: Thirty - one cases were successful, no complications appeared. One case had primary ptosis and 1 case had recurrent conjunctival sac contracture.
CONCLUSlON:lt is recognised that the methods of oral mucosa transplantation in severe contracted conjunctival sac after ocular prosthesis implantation are effective on those cases.
