Objective To investigate the application of numerical simulation technique in supraorbital and frontal osseous defect.Methods The data of the patients with complex supraorbital and frontal osseous defects were obtained by helix CT scan.Numerical model based on the data was built up by computer.And the true model was produced by Rapid Prototyping.Being stimulated before this operation.the model was directly used in the operation.Results All of these 12 patients(one of defect of brow,four fracture of brow and zygoma,seven of old fracture of brow and zygoma)in this study were satisfied and their brows were symmetry after operation.All of them were satisfied after 1 or 2 years,without implantation exposure and transfiguration except one with infection.Conclusion Based on numerical technique difficulties of repairing,complex supraorbital and frontal osseous defect could be resolved by such process as collecting the bone data,stimulating operation by true models,and producing implantation before the operation.The accuracy of these operations can be improved.

Objective To observe the changes of serum IGF-I,VEGF levels in premature infants,and to dis-cuss the predicting values for the development of ROP;Methods Preterm infants admitted into those whose birth weight ( BW)≤1 500g and ( or) gestational age ( GA)≤31 weeks joined in ROP-screen,and those who were diag-nosed as ROP according to ICROP were included into ROP group.In the same time,those who didn't develop ROP were divided into the control group.Serum IGF-I,VEGF were measured one week from their birth or correct gestational age of 31 weeks.Serum IGF-I, VEGF were evaluated with ELISA method.Results The concentration of IGF-I, VEGF:Group ROP[(20.65 ±11.11)μg/L,(195.61 ±105.98)ng/L] were all significantly lower than the control group [(42.86 ±18.72)μg/L,(363.59 ±101.08)ng/L](all P<0.01).There were significant different of birth weight[ROP group (1 229.69 ±232.37)g,the control group (1 401.32 ±171.78)g;t=4.144)],GM[ROP group (3.20 ±1.23)mmol/L,the control group (3.70 ±1.17)mmol/L;t=2.082],the time of oxygen inhaling[ROP group (32 ±22)d,the control group (21 ±12)d;t=-2.856],oxygen inhalation mode(the percentage of mechanical ventilation)[ROP group 33/48(68.8%),the control group 16/50(32.0%);χ2 =16.363] and fertilization way(the percentage of test tube baby)[ROP group 13/48(27.1%),the control group 4/50(8.0%);χ2 =6.262] between ROP and control group (all P<0.05).Conclusion The low serum IGF-I(<28.08μg/L),VEGF(<232.89ng/L) of a premature in the first week or correct gestational age of 31 weeks and (or)BW≤1 500g would probably suggest the development of ROP.

Observation on the effect of whole rice and whole wheat as sole food on the growth of young rats are furtherly made. The results showed that both whole rice and whole wheat showed no significant difference in the growth of young albino rats, but the difference between the rice group and rice plus leafy vegetable and egg group and that between the wheat group and wheat plus leafy vegetable and egg group are highly significant. Addition, of small amount of vegetable and egg alternatively as supplementary food significantly enhanced the nutritive value, in terms of growth effect, of both whole rice and whole wheat.

Objective To find out sterilization quality of pulsating vacuum sterilizer for better sterilization effect.Methods The sterilization quality was monitored by physical,chemical and biological methods.Results 4,576 subjects were involved in the test.Such data were obtained as the qualification rate for temperature,the one by chemical indicator card,the one by B-D test and the one by biological indicator,which were 99.6%,99.8%,99.9% and 100% respectively.Conclusion Above data proves that the sterilizer is in normal condition.

Objective:To improve the knowledge on propythiouracil(PTU)-induced antineutrophil cytoplasmic antibody(ANCA)-associated vasculitis.Methods:6 cases of PTU-induced ANCA-associated vasculitis were analyzed on clinical manifestation,laboratory and biopsy findings,therapy and prognosis.Results:All patients with Grave's disease had been treated with PTU from 2 months to 7 years suffered from ANCA-associated vasculitis, which can also appear after withdrawal of PTU. Clinical manifestations are different with only skin, joint, muscle involvements on mild cases or lung, renal and hematological involvement on severe cases. Sera from all patients were anti MPO-ANCA positive. All patients responded to withdrawal of PTU and administration of prednisone and immuno-suppressants well with ANCA declined or turned to negative.Conclusion:PTU can induce ANCA-associated vasculitis in the part of which lung and kidney can be seriously involved. Early withdrawal of PTU and administration of immunosuppressive agents might improve the prognosis.

Objective To investigate the effect of hypoxia-inducible factor (HIF)-1α and vascular en-dothelial growth factor (VEGF) on the angioge-nesis of rheumatoid arthritis (RA). Methods The collagen-induced arthritis (CIA) model was set up in male Wistar rats. The pathological angiogenesis and expression of HIF-1α and VEGF in the synovia different time points were observed by H&E and immunohistochemistry staining. Results The expressions of HIF-1α and VEGF on CIA synovium were significantly elevated and their expression increased gradually with the prolonged disease course. Both synovial HIF-1α expression and VEGF expression were correlated significantly with the pathological angiogenesis score. Synovial lining and sublining HIF-1α expression were correlated significantly with VEGF expression respectively. Conclusion H1F-1α may play an important role in the pathogenesis of RA by upregulating the expression of VEGF and then promoting angiogenesis.

Objective To evaluate the therapeutic effect of laparoscopic hernioplasty for inguinal hernia in aged males.Method Forty cases of inguinal hernia in aged males were treated with laparoscopic hernioplasty(group L),while other 46 cases were treated with traditional inguinal hernioplasty(group S).Results To compare with group S,the time be in hospital and the time leave off the bed were significantly shorter in group L(P＜0.01 or＜0.05),but the mean operation time were longer and the operation expenses Was higher in group L(P＜0.05).Followed up for 2-47 months,there were no recurrence in two groups.Conclusions Laparoscopic hernioplasty for inguinal hernia in aged males can shorten the hospitalization time,quicken postoperative recovery.The comphcation is little and the wound ache is light.Along with the further improvement of laparoseopic technique and the amelioration of laparoscopic instrument.the opera-tion time will further shorten,the expenses also will descend.It will be a ideal way for the therapy of inguinal hernia in aged males.

Objective To explore the expression status of carbonic anhydrase Ⅲ (CA Ⅲ) from quadriceps femoris muscle in two kinds of muscle clinical phenotype (skeletal muscle atrophy group and skeletal muscles non-atrophy group) of chronic obstructive pulmonary disease (COPD).Methods Totally 37 inpatients from our hospital,were divided into 11 patients without COPD and 26 patients with COPD,in addition,according to body mass index,fat free mass index and quadriceps cross-section diameter,patients with COPD were divided into 14 skeletal muscles non-atrophy patients (SMNA)and 12 skeletal muscle atrophy patients (SMA).CA Ⅲ concentration of femoris quadriceps specimens was quantitatively determined using Western blot methods,CA Ⅲ mRNA expression levels of femoris quadriceps specimens were also quantitatively measured using RT-PCR,then compared among the 3 groups.Results There was significant difference in CA Ⅲ quantitative concentration and CA Ⅲ mRNA expression level in each group (P ＜ 0.05),further more,CA Ⅲ concentration expression level was significantly higher (P ＜ 0.01)in SMA group (1.260 ± 0.068) than in SMNA group (1.110 ± 0.014),the latter was significantly higher (P ＜ 0.01) than in the control group (1.000 ± O.062).CA Ⅲ mRNA expression level was significantly higher(P ＜ 0.01) in SMNA group(2.170 ±0.412) than in the control group(1.000 ±0.115),and was significantly lower than in SMA group (3.770 ± 0.788 ; P ＜ O.01).CA Ⅲ concentration and CA Ⅲ mRNA expression level increased at equal pace in SMNA group and SMA group,however,CA Ⅲ quantitative concentration and CA Ⅲ mRNA expression level were inconsistent in the two groups.Conclusion The expression status of CA Ⅲ in quadriceps femoris muscle was different in two kinds of muscle clinical phenotype of COPD.
