Objective To study the prenatal genetic diagnostic methods for hemophilia A fetus.Methods From 2002 to 2006,19 hemophilia A families were diagnosed either by long distance-polymerase chain reaction(LD-PCR)for factor Ⅷ intron 22 inversion or by the DNA polymorphism genetic linkage analysis of factorⅧin the Beijing Chaoyang Hospital.Results (1)Totally 19 women,with 22pregnancies received the prenatal diagnosis of fetal hemophilia A.The average week at diagnosis was 23(17-34)weeks.All the direct fetal blood sampling(DFBS)were successful.There was no fetal-loss caused by the procedures.(2)Of the 19 hemophilia A families,14 appeared to be factorⅧintron 22inversion,in which 16 prenatal diagnoses were done,10 fetuses were diagnosed as genetical hemophilia A patients,and 6 fetuses were normal.(3)Using combined polymorphism genetic linkage analysis 6 prenatal diagnoses were done,including one woman's two pregnancies,in which both her fetuses were diagnosed as genetical hemophilia A patients.(4)Factor Ⅷ levels of 16 fetuses were measured,and 6 fetuses were unmeasured either because the pregnancy weeks were lower than 20 weeks or the parents refused.Factor Ⅷlevel ranged from 0 to 198%.There were 11 fetuses whose factor Ⅷ levels were lower than 10%.Ten of them were diagnosed to be genetical hemophilia A patients,and in only one boy the factorⅧlevel was 2%,but the genetic diagnosis was normal and for one year's follow up he was doing normal.Conclusion LDPCR combined with polymorphism genetic linkage analysis enables a quick and correct detection ofhemophilia A carrier.For a carrier pregnancy.prenatal diagnosis could be done for the male fetus.Factor Ⅷ deficiency of the fetus could help make the diagnosis but the final diagnosis should be based on genetic evidence.

Objective To measure the average value of CT lung density at the phase of end inspiration and end expiration in children under 5 years.Methods Sixty patients with normal lungs who underwent chest CT for reasons caused by trauma etc.in our institute from January 2010 to March 2012 were enrolled to the study.All of the patients were divided into end inspiration group and end expiration group through random number table.CT images of the phase of end inspiration and end expiration were taken.Three levels of CT images were chosen to measure the lung density,which were 2 cm above the arch,1 cm below the carina and 2 cm above diaphragm.Lung density was measured at anterior,posterior,lateral,medial and central of the images at each level in each lung.The average lung density of each and entire lung were respectively calculated.The influence of phase,level,location was quantified using analysis of variance methods and LSD method.Results The average lung density at end inspiration was (-766 ±56)HU for the left,right and both lung.At end expiration,the average lung density of the left,right and both lungs was (-625 ± 86),(-647 ± 85) and (-636 ± 86) HU respectively.The average densities at anterior,posterior,lateral,medial and central of the left lung at end inspiration were (-798±63),(-733±68),(-767±64),(-754 ±65),(-775 ±63)HU respectively.The average densities at anterior,posterior,lateral,medial and central of the right lung were (-796 ± 70),(-736 ± 65),(-769 ± 64),(-754 ± 62),(-776-± 59) HU respectively.At end expiration phase,the average densities at anterior,posterior,lateral,medial and central of the left lung were (-692±91),(-555±116),(-639±91),(-598±103),(-640±98) HU respectively.The average densities at anterior,posterior,lateral,medial and central of the right lung were (-712 ± 90),(-575±121),(-657±90),(-619±95),(-670±87) HU respectively.The statistical differences of these five measurement areas were significant at both inspiration and expiration phase (F=12.55,11.29,23.31,25.47,P＜0.01).The posterior lung density was the highest and the anterior was the lowest.As for the other measurement areas,in descending order were medial,lateral,and central.Conclusion The lung density at end inspiration and end expiration in children under 5 years old is described to provide reference for the clinical work.

Objective To develop a technique for the detection of genotypes of ?-thalassemia, which was rapid and automatical with high through-put.Methods The Real Time PCR and dissociation curve analysis (D.C) were carried out by using SYBR Green1 on ABI7000.Positive results of the 3 SYBR-Q-PCRs were defined by the -dF/t℃≥cut off value of the peak at the specific Tm for each right PCR product.Three PCR products were recombined with the T-vector.The correct positive clones were selected by sequencing.Standard curves of the CT vs. log values of copies were done from a serious dilutions of the recombinant plasmid DNA which served as the template in SYBR-Q-PCRs.Results The conditions of the PCR including concentrations of primers, thurmocycler program etc.were optimized.Specific Tm values for the 3 SYBR-Q-PCRs were 82.5?1℃, 83.0?℃ and 84.0?1℃ respectively. The standard curves for p800 bp and p206 bp DNA showed a good linear relationship between CT and log value of the copies of the template DNA ranging from 10~5 copies to single copy. Sensitivity of the technique were at least 10~1 to 10~2 times higher than that of the regular PCR plus gel electrophoresis method.The techniques and reagents showed very good reproducibility and stability besides the high sensitivity. The ?-thalassemia 1(??/--SEA), Bart′s Hydrops Syndrom (--SEA/--SEA), deletion type and non-deletion type of HbH diseases, and homozygote of ?-thalassemia-2 were diagnosed by the methods.Conclusion The genotypes of the ?-Thalassemia could be diagnosed by the Real-time PCR with SYBR Green1 combined with the melting curve analysis.rapidly, automatically, accurately with high throughput and without dual fluorescent labeled probe.

AIM: To investigate the changes of the redox status and the antioxidative capability in the tissue of malignant tumors. METHODS: The carcinoma tissues collected from 42 patients with primary cancer in digestive tract (13 cases of esophageal cancer, 14 cases of gastric cancer and 15 cases of colorectal cancer),the corresponding paratumor mucosa tissues were taken as the control samples. The content of oxidized and reduced glutathion (GSSG and GSH), oxidized and reduced coenzyme II (NADP+ and NADPH) were measured, the GSH/GSSG, NADPH/NADP+ ratios, and the GSH/GSSG, NADPH/NADP+ redox potentials were calculated according to Nernst formula. RESULTS: The levels of GSH and NADPH in cancer tissues were significantly higher than those in corresponding paratumor tissues (P0.05). CONCLUSIONS: The significant increase in GSH and NADPH contents in cancer tissues indicates a notable enhancement of its antioxidative capability compared with the corresponding paratumor tissues. Based on this changes, the redox potential in the cancer tissues has only slightly reductive shift, which may suggest an apparent oxidative stress existed in the cancer tissues.

Objective To evaluate the outcomes of distal leg and foot-ankle reconstruction with rotated single pedicel reverse sural neurocutaneous island flaps. Methods From June 2011 to January 2016, seventeen distal leg and foot-ankle defects cases repaired with rotated single pedicel reverse sural neurocutaneous island flap were analyzed retrospectively. In this study, 13 cases were male, and 4 cases were female. Age ranged from 25 to 65 years old, with an average age of 42.0 ± 8.3 years. Seven cases were distal leg defects, 3 cases were ankle defects, 3 cases were heel defects, and 4 cases were acrotarsium defects; all cases had bone and tendon exposure. The defects ranged from 5.0 cm × 7.0 cm-6.0 cm × 12.0 cm. The flap size ranged from 5.0 cm × 7.0 cm-8.0 cm × 15.0 cm. Results All 17 cases survived completely, without thanatosis, blisters and vascular crisis. The follow-up period was 12-48 months, and the mean was (20.0 ± 11.1) months. The color and elasticity of the flaps was excellent, with satisfactory appearances. Function and appearance of donor sites was not affected. Conclusions The rotated single pedicel reverse sural neurocutaneous island flaps have no injury on main nerves and arteries. The flaps have wide rotation angle and less invalid fold in the pedicel. The simple operation has satisfactory effects and high survival rate. It is a relatively easy procedure that can be applied toward repairing of distal leg and foot-ankle soft tissue defect.

Objective To evaluate the outcomes of thumb reconstruction with dorsal thumb rotated single pedicel reverse island flap.Methods 49 thumb-tip defects cases with dorsal thumb rotated single pedicel reverse island flap were analyzed retrospectively.37 dorsal thumb reverse island flap were performed,and 12 ulnar-dorsal reverse island flaps were performed.Results The operation time was 40-60 minutes.The mean time was 45 minutes.All 49 cases survived completely.The color of the flaps was purple,and blisters in the surface of the flaps after 1-2 days in 2 cases.After took out stitches partly,the blisters were dried and crusted,the color of the flaps with better blood circulation was normal.The follow-up period was 3-24 months,all thumbs had satisfactory appearances and functions.The two-point discrimination was 6-9mm in flaps inosculated with nerve,that was 8-10 mm in flaps inosculated without nerve.The color,texture and elasticity of flaps were excellent,and the donor sites had not been defected.Conclusion Dorsal thumb rotated single pedicel reverse island flap is a reliable option to restore function as well as appearance,long vascular pedicle with skin strap,wide rotation angle,high rate of survival.It avoided damages to the well-known arteries and nerves.It is a relatively facile procedure that can be applied toward resurfacing thumb tip defects.

Objective To observe the effect of acute hypervolemic hemodilution (AHH) with two kinds of hydroxyethyl starches including Voluven and HES on the renal function of emergency surgery patients with brain injury.Methods This study involved 54 brain injury patients treated with emergency surgery,who were randomly divided into Voluven group ( AHH130 group),HES group ( AHH200 group) and Ringer's lactate group (LR group),with 18 patients in each group.All the patients were managed with inhalation anesthesia.ECG,MAP,CVP and SpO2 were observed in operation.The blood urea nitrogen (BUN),urine creatinine ( BCr,UCr),urinary albumin (ALB) and urinary α1-microglobulin ( α1-MG) were detected before AHH ( T0 ),at the end of operation ( T1 ),at 4 hours ( T2 ),day 1 ( T3 ),day 2 (T4) and day 3 (T5) after operation.The creatinine clearance (CCr) and fractional sodium clearance (FSC) were calculated and the urine output,fluid replacement,blood loss and blood transfusion recorded.Results The HR,CVP and MAP in the three groups were within the normal range of variation at all time points,with statistical difference for comparison between groups and within group ( P ＞ 0.05 ).There was no significant difference in urine output and blood loss,while the intraoperative fluid volume and blood transfusion in the AHH130 group and the AHH200 group were significantly less than those in the LR group (P ＜ 0.01 ).There was no statistical difference in aspects of BUN,BCr and urinary ALB at each time point between and within the three groups ( P ＞ 0.05 ).After treatment with AHH,the urinary α1-MG level in the AHH130 group and AHH200 group was significantly increased ( P ＜0.01 ),which was decreased at T5 but was still higher than that at T0 ( P ＜ 0.01 ),and was higher than that in the LR group at all time points (P＜0.05).After treatment with AHH,CCr was decreased in the AHH130 group and AHH200 group,which reached the lowest level at T2,with statistical difference compared with the levd at T0 ( P ＜0.01 ).Then,CCr was recovered to normal at T5.FSC in the three groups after AHH treatment was increased slightly and the most significantly at T2,which was not statistically different compared with that at T0 ( P ＞ 0.05) and FSC was not statistically different between and within groups at other time points (P ＞0.05).All the values about the renal function in all the groups changed within the normal range at each time point.Conclusions AHH with Voluven or HAES is a feasible and safe blood conservation measure that can significantly reduce the allogeneic blood transfusion but exert insignificant effect on renal function of the brain injury patients with normal renal function before emergency surgery.

Objective To explore the feasibility and efficiency of the treatment of lumbar degenerative diseases after transforaminal lumbar interbody fusion(TLIF)and posterolateral fusion(PLF)procedures in which unilateral pedicle screw fixation was used.Methods From December 2006 to August 2008,78 cases with the lumbar degenerative diseases who received lumbar posterolateral fusion were analyzed.There were 48 cases of which underwent TLIF and PLF procedures with unilateral pedicle screw fixation(unilateral group),including 25 males and 23 females with an average of 47.6 years;and 30 cases of which underwent TLIF and PLF procedures with bilateral pedicle screw fixation(bilateral group),including 21 males and 9 females with an average of 50.5 years.The clinical effects between the two groups were evaluated with Oswestry disability index and visual analogue score(VAS)index.The operation time,blood loss,fusion rates and intervertebral collapse rates were also compared.Results Oswestry disability index,low back pain VAS index and skelalgia VAS index in both groups showed statistical significance between preoperation and 3 months,or 3 months and 1 year postoperatively.There was no difference in score improvement between the two groups.There were difference in operation time,blood loss and cost of hospitalization between unilateral and bilateral group.The former was lower.There was no difference in postoperative length of stay between the two groups.The fusion rate of unilateral group and bilateral group were 91.7%(44/48)and 93.3%(28/30),respectively.Conclusion Auto graft combined with unilateral pedicle screw fixation provids better spinal instant stability.TLIF and PLF with unilateral pedicle screw fixation was a satisfactory method in treating degenerative disease of lumbar vertebrae.
