ObjectiveTo investigate the dosage of protamine to counteract heparin in patients with different pH values of after - surgery plasma of congenital heart defect.MethodsThe clinical data of 108 patients during March 2011 to April 2011 with congenital heart diseases who underwent cardiopulmonary bypass(CPB) surgery were reviewed.The volumes of chest tube drainage were analyzed to investigate the dosage of protamine in patients with different pH values in plasma.ResultsThe dosages of protamine and the volumes of chest tube drainage[ ( 136.8 ± 22.8 ) ml] in patients with an acidic environmental plasma were higher than the patients in another group [ ( 112.6 ± 22.7 ) ml ] ( P＜ 0.01 ).In patients with non-acidic environments,the mean ratio of dosage of protamine to heparin was 1.23:1 ; meanwhile in patients with pH＜7.30 or base excess (BE) ＜ -6,the mean ratio was 1.86:1.It suggested the dosage of protamine increased significantly in patients with an acidic environmental plasma.ConclusionsDifferent plasma pH values could change the dosage of protamine after cardiopulmonary bypass,and the acidic environment would increase the dosage of protamine and increase the volume of chest tube drainage after surgery.When pH ＜ 7.30 or BE ＜ - 6 at the end of CPB,to correct acid-base balance first and then calculate the dose of protamine was recommended.

Objective To investigate the curative effects of curcumin(CUR)or dexamethasone (DXM)on ischemia-reperfusion injury(IRI)of rat lung grafts.Methods Male SD rats were randomly divided 4 groups:CUR group(CUR was administered intraperitoneally to both donors and recipients at 3 h prior to operation);DXM group(DXM was administered intraperitoneally at 30 min prior to operation);vehicle group(Animals were injected with the DMSO to both donors and recipients at 3 h prior to operation);sham group(Time-matched control animals underwent the same surgery,except that no graft was implanted).Six animals were sacrificed at different reperfusion periods of 2 h and 24 h,respectively.Oxygenation indexes(PO_2/FiO_2),lung injury scores,wet/dry ratio(W/D)and myeloperoxidase(MPO)activity in the transplanted lung were measured.Malondialdehyde(MDA), total anti-oxidative capacity(TAOC),tumor necrosis factor(TNF)-?and interleukin(IL)-6 in the transplanted lung and serum were determined.Results The levels of LPV PO_2/FiO_2 were significant- ly higher in the CUR and DXM groups than in the vehicle groups both 2 and 24 h after reperfusion,re- spectively(P

The pancreatic enzyme-II type collagenase digestion method was adopted for primary culture of osteoblasts, inoculation and passage. They were identified by alkaline phosphatase dye-liquor. N-butanol extract fractions from different processed products of Cibotium barometz were prepared. The above osteoblasts were jointly cultured with protocatechuic acid, protocatechuic aldehyde, kojic acid and the mixed control liquid of the above three substances, and their proliferation was detected by CCK-8. Various n-butanol extract fractions from different processed products of C. barometz showed a significant proliferative effect on osteoblasts in the order of the wined > the heated > the salted > the sand-heated and wined system > the alcohol-processed > the steamed > the crude. The q test showed no significant difference among sand-heated, alcohol-processed and steamed C. barometz, no significant difference between heated and salted C. barometz. Various control substances also showed a certain proliferative effect on osteoblasts in the order of the mixed control > protocatechuic aldehyde > protocatechuic acid > kojic acid. The q test showed no significant difference between protocatechuic aldehyde and protocatechuic acid. All of n-butanol extract fractions from different processed products of C. barometz showed a significant effect on osteoblast proliferation, of which wined C. barometz showed the best effect. All of phenolic compounds such as protocatechuic aldehyde, protocatechuic acid and kojic acid showed a significant proliferative effect on osteoblasts.

Objective:To investigate the application valve of bFGF to improve the viability of subdermal vascular network flap.Methods:Four white healthy pigs were used,each pig had 6 SVNF on back,16cm?4cm,totally 24 flaps were divided randomly into 2 groups:The bFGF groups and the control groups.On postoperative day 6,we observed the appearance of the flaps.The survival area of each flap was measured and the flap was harvested for histological analysis and the density of angiogenesis was also examined.Results:On postoperative day 6,the survival rates of the bFGF group and the control group were (81.2?1.7)% and (66.2?1.8)% respectively,the angiogenesis density of the middle and the distal segment in the bFGF group was (16.7?6.0)/mm2,(29.7?5.5)/mm2,(14.9?6.0)/mm2 respectively,while (16.6?4.0)/mm2,(21.4?5.2)/mm2,(3.5?5.1)/mm2 respectively in the control group.The bFGF group was superior to the control group in the appearance and histological analysis of the flaps.Conclusion:The results suggest that the injection of bFGF locally can promote the survival rate by accelerating the blood circulation of the SVNF’ bottom and edge,shorten the division time of SVNF and broaden the ratio of length and width.

This study compared the decoction's HPLC figures of the different processed rhizomes of Cibotium barometz including the raw, the sand-baked, the wined, the steamed and the salted, on the basis of which, with the sand-baked Drynaria fortunei decoction as the positive control group, comparingall groups' decoction, concentration of which was 104.2 g x L(-1), for 4 weeks, by their effects (s-TRAP and total scores of OPG, Ca, P, IL-6, TNF-alpha and IL-1) on retinoic acid induced male rats osteoporosis. The experiment results showed the sand-baked and the wined were better than the steamed, the salted and the raw;in the processing methods' selection, the sand-baked was a better heating method than the steamed and the rice wine was the better excipient than the salt. It provided a reference to explain the processing principle of rhizomes of C. barometz and work mechanism of anti-osteoporosis.

Objective To analyze and evaluate the effects of the tissue engineering bladder reconstruction on the upper urinary tract structure and function.Methods The 8 male beagles were randomly divided into the two groups:sham-operation group (group A,n=4)and the collagen scaffold repair group (group B,n=4).The bladder defect animal model was established in the group B by using the collagen scaffold materials to repair the bladder.The renal function related biochemical indicators were detec-ted and the renal Doppler ultrasonic examination was performed in each group before repair and in 23 weeks after repair.The speci-mens from the two groups were performed the gross morphology observation and the histology examination on postoperative 24 weeks.Results The renal Doppler ultrasound examination showed the normal kidney morphology and normal blood flow signal.In the general observation,no calculi and neoplasm were found in the kidney and ureter of the experimental dogs.The renal function related biochemical indicators had no statistically significant differences between the two groups(P>0.05).The histological exami-nation indicated that the organization structure was integrity,the nephrons in each group had no obvious pathological changes.Con-clusion Using the collagen scaffold materials to reconstruct the canine bladder has no adverse influence on the upper urinary tract structure and function,this tissue engineering approach has good feasibility.

Objective To investigate the clinical significance of generalized epilepsy with febrile seizures plus(GEFS+ ). Methods The data of one family with GEFS+ were retrospectively analyzed by studying clinical manifestations, physical examinations, electroencephalogram(EEG), 24 hours dynamic EEG monitoring, et al. Some of the patients were examined by CT. Results Ⅳ 12, her chief complaints when admitted to hospital were frequent spasm for 3 days. She began to appear febrile seizures (FS) from 8 months after birth, and frequent generalized tonic - clonic FS appeared during that time. There were 36 people in 5 generations of the family including 14 patients (8 males and 6 females) ,aged from 4 years and 5 months to 82 years. FS presented in 8 cases (Ⅱ 2, Ⅲ1, Ⅲ4, Ⅲ6, Ⅳ1, Ⅳ11, Ⅳ17, Ⅴ2),febrile seizures plus(FS +) in 4 cases ( Ⅳ2, Ⅳ12, Ⅳ13, Ⅳ14), ES + and absence seizures in 1 case ( Ⅴ1 ), uncertain type in 1 case (Ⅰ2). The results of EEG indicated that 12 cases were normal and 4 cases with FS+ and 1 case with absence seizures had epileptic discharges. Apart form Ⅳ13, Ⅳ14 who were treated with magnesium valproate, the dosage for the other patients decreased, or medicine terminated or without medicine, and all the patients had no recurrence of seizures. The intelligence, movement development and neurological examinations of the family were all normal. Head CT scan of 3 cases were normal. Conclusions GEFS+ is autosomal dominant inheritance disease with conspicuous genetic heterogeneity and phenotypic heterogeneity. The apprehension of GEFS+ plays an important role in diagnosis and differential diagnosis of epilepsy in childhood.
