OBJECTIVE: To explore alcohol pharmacokinetics as well as acetaldehyde level in peripheral blood in human subjects with different ALDH2 genotypes after drinking. METHODS: Venous blood samples of 14 unrelated volunteers were collected. Polymerase chain reaction-restriction fragment length polymorphism technology was adopted for DNA extraction and ALDH2 genotyping. The volunteers were asked to drink beer at certain doses. The concentration of alcohol and acetaldehyde were assayed by headspace gas chromatography method at different time. The pharmacokinetic parameters were calculated. RESULTS: According to the results of electrophoresis, 5 people carried ALDH2*1/*1 as wild group and 9 people carried ALDH2*1/*2 as mutation group. The good linear range of alcohol and acetaldehyde were 0-1 570.7 microg/mL and 0-5.1772 microg/mL, respectively. The AUC values of alcohol and acetaldehyde and the t1/2Z value of alcohol were higher in the mutation group than that in the wild group. But the CL/F value of alcohol was lower in the mutation group than that in the wild group (P<0.05). CONCLUSION After the consumption of alcohol, alcohol and acetaldehyde metabolism in blood slow down in ALDH2*1/*2 mutation group influenced by the inhibition of enzyme activity, leading to the accumulation of acetaldehyde in peripheral blood, thus reinforcing their effects in the body.

OBJECTIVETo evaluate the randomized controlled trials on preventing and treating restenosis after percutaneous coronary intervention (PCI) with Chinese medicine adopting the principle of evidence-based medicine (EBM).

METHODSPertinent literatures were retrieved roundly, and scored depending on Jadad Quality Scale. Meta-analysis was applied on the total effect of outcomes reported using RevMan 4. 2 software. Moreover, the sensitivity was analyzed, the publication bias was identified with funnel-plot and the adverse reaction of medicine was reported.

RESULTSAmong the 17 literatures met the inclusion criteria, only two double-blinded trials were appraised as high quality. The analysis on the recurrence rates of restenosis post-PCI and angina pectoris in patients treated with Chinese medicine illustrated that the rates in the treatment group were all lower than those in the control group with statistical significance (P < 0.01). Sensitivity analysis revealed a relatively stable result of the evaluation. Funnel-plot displayed an asymmetrical figure, indicating the possible existence of publication bias.

CONCLUSIONTCM has definite therapeutic effect on preventing and treating restenosis after PCI and reducing the recurrence rate of angina pectoris in patients.

BACKGROUNDSural neurofasciocutaneous flap has been popularly used as an excellent option for the coverage of soft tissue defects in the lower third of leg, ankle and foot, but its free transplantation has been rarely reported. The objective of our work was to investigate the operative technique and clinical results of repairing the soft tissue defects of hand and forearm with free peroneal perforator-based sural neurofasciocutaneous flap.

METHODSBetween May 2006 and March 2007, 10 patients including 7 men and 3 women were treated. Their ages ranged from 22 to 51 years. They presented to emergency with large soft tissue defects of 16 cm x 7 cm to 24 cm x 10 cm in size in hand and forearm after injured by motor vehicle accidents (2 cases) or crushed by machine (8 cases). Thorough debridements and primary treatments to associated tendon ruptures or bone fractures were performed on emergency. And free peroneal perforator-based sural neurofasciocutaneous flaps were transplanted when the wound areas were stable at 5 to 7 days after emergency treatment. The flaps were designed along the axis of the sural nerve according to the shape and size of the soft tissue defects, with the peroneal perforator above the lateral malleolus as the pedicle and along with a part of the peroneal artery for vascular anastomosis. Then the flaps were harvested to repair the recipient sites with the peroneal artery anastomosed to the radial (or ulnar) artery and the peroneal veins to one of the radial (or ulnar) veins and the cephalic vein respectively. The flap sizes ranged from 18 cm x 8 cm to 25 cm x 12 cm. The donor areas were closed by skin grafts.

RESULTSAll of the 10 flaps survived after surgeries. Marginal necrosis occurred in only 2 cases. The skin grafts survived entirely in the donor sites, and no obvious influence on the donor legs was observed. All of the transplanted flaps presented favourable contours and good functions at 9 to 12 months' follow-up.

CONCLUSIONSPeroneal perforator-based sural neurofasciocutaneous flap has favourable appearance, constant vascular pedicle, reliable blood supply, large size of elevation, and minimal influence on the donor site. The free transplantation of this flap offers a satisfactory alternative for repairing the large soft tissue defects of forearm and hand.

OBJECTIVETo investigate the effects of sodium alginate gels on marrow mesenchymal stem cell transplantation for repair of spinal cord injury (SCI) in mice.

METHODSIn the present study, effects of different sterilization methods and concentrations of sodium alginate gels were examined. Marrow mesenchymal stem cells (mMSCs) were isolated from mice and cultured. Cells were cultured with sodium alginate gels and MTT assay was applied to determine the cell viability. Mice spinal cord injury was induced by spinal cord transection. mMSCs were transplanted into the cavity of injured spinal cord with sodium alginate gels. The effects of sodium alginate gel were assessed by BMS scales and immunofluorescence staining for NF-200.

RESULTSCompared with liquid form, solid form sodium alginate gel prepared with high pressure vapor sterilization had a better effect on cell viability. SCI mice treated with 10 % sodium alginate gel and mMSCs achieved higher score in BMS scale as well as higher expression of NF-200 compared with the untreated SCI group.

CONCLUSIONSodium alginate gel prepared with solid form sterilization induces mMSCs proliferation and thus can be used as the carrier of stem cell in treatment of SCI.

This study was purposed to investigate the diagnostic value of fluorescence in situ hybridization (FISH) technique for the childhood acute myeloid leukemia (AML). The medical data of 179 children with AML (aged ≤ 16 years) were retrospectively studied, who were initially diagnosed in our hospital from April 2005 to April 2010. Through the analysis of the results of FISH, chromosome banding analysis and polymerase chain reaction, the difference and complementarity between FISH and other 2 methods for detecting the fusion genes were explored. The results indicated that the detection rate of genetic abnormality with FISH was higher. The PML/RARα probe was used in 27 AML-M3 patients, 22 out of whom were evaluated as PML/RARα positive. The AML1/ETO probe was used in 24 AML-M2b patients and all of them were evaluated as AML1/ETO positive. The CBFβ/MYH11 probe was used in 4 AML-M4Eo patients and all of them were evaluated as CBFβ/MYH11 positive. It is concluded that FISH is a sensitive method for detecting fusion genes and the results of FISH have a good correlation with the chromosome banding analysis and polymerase chain reaction. The combination of FISH with other 2 methods improves the detection rate of genetic abnormality, which is useful for the diagnosis and typing of childhood AML.

OBJECTIVETo study the relationship between inflammation and neointimal proliferation after coronary stent implantation in porcine model.

METHODSTwenty normal minipigs were randomly divided into group A (implanted with 316L bare metal stents), group B (implanted with 605L bare metal stents), group C (implanted with PLGA coating 605L stents), and group D (implanted with rapamycin-loaded PLGA coating 605L stents). Each minipig was implanted with two same stents in left anterior descending artery and right coronary artery. Four weeks later, the animals were sacrificed and histomorphometric measurements on the stent-segment coronary arteries were made to calculate the correlation between inflammation area and neointimal area.

RESULTSGroup D had the smallest neointimal area [(0.64 +/- 0.38) mm2, P < 0. 001] and inflammation area (median 0.00 mm2, P = 0.009) among all the groups, while there were no statistical differences among group A, B, and C in neointimal area [(2.09 +/- 0.90), (2.11 +/- 1.07), and (1.42 +/- 0.35) mm2 respectively] and in inflammation area (0.22 , 0.21, and 0.09 mm2, respectively). Bivariate correlation analysis showed that the inflammation area was positively correlated with the neointimal area (P < 0.001, correlation coefficient = 0.719). When stent type, mean injury score, and EEL area were adjusted, partial correlations analysis showed that the inflammation area was still positively correlated with the neointimal area (P = 0.01, correlation coefficient = 0.498).

CONCLUSIONInflammation promotes the neointimal proliferation after coronary stent implantation. Sirolimus-eluting stent may reduce the inflammatory response.

OBJECTIVETo investigate the diagnosis and treatment of ovotesticular disorders of sex development (DSD) in children.

METHODSWe reviewed the clinical data of 9 cases of ovotesticular DSD admitted in our department from 1988 to 2007.

RESULTSThe patients ranged in age from 9 months to 9 years, 7 raised as males and 2 as females. As for the karyotype, 4 cases were 46,XX, 2 were 46,XX/46,XY, 1 was 46,XY, and the other 2 had no karyotype data. All of them presented with obscure external genitalia: perineal or penoscrotal hypospadias with or without cryptorchidism in males and hypertrophy of the clitoris in females. They were diagnosed with ovotesticular DSD by gonad biopsy and underwent genitoplasty.

CONCLUSIONThe gender assignment of the ovotesticular DSD patient was chiefly based on the development of external genitalia, dominant gonad, karyotype and the parent's will. Laparoscopic technology is recommended in gonad biopsy and orchiopexy during the treatment of ovotesticular DSD.
