OBJECTIVE:To observe the effects of epalrestat combined with lipoic acid on nerve function,oxidative stress and inflammatory reaction in patients with diabetic peripheral neuropathy(DPN). METHODS:From Jan. 2013 to Jan. 2016,150 pa-tients were selected from our hospital and then divided into group A,B,C according to random number table,with 50 cases in each group. Group A was given Lipoic acid injection 600 mg,ivgtt,qd;group B was given Epalrestat tablet 50 mg,po,tid;group C was given lipoic acid+epalrestat,same usage and dosage as above. TSS score,MNCV,SNCV,oxidative stress indexes (SOD and MDA)and inflammatory indexes(TNF-α and IL-6),as well as blood pressure,blood lipid and blood glucose indexes were compared among 3 groups before and after treatment. The occurrence of ADR were observed. RESULTS:Before treatment, there was no statistical significance in above indexes among 3 groups (P>0.05). Compared to before treatment,TSS score, MDA,TNF-α and IL-6 levels of 3 groups were decreased significantly after treatment;MNCV and SNCV were speeded up signifi-cantly,and SOD level was increased significantly;each index of group C was better than that of group A and B,with statistical significance(P<0.05),but there was no statistical significance between group A and B(P>0.05). SBP and FPG after treatment of 3 groups were decreased significantly than before treatment,while HDL-C was increased significantly,with statistical signifi-cance(P<0.05);there was no statistical significance among 3 groups(P>0.05). No obvious ADR was found in 3 groups. CON-CLUSIONS:Epalrestat combined with lipoic acid can effectively improve nerve function in DPN patients by inhibiting oxidant stress and inflammatory reaction with good safety. The effect of drug combination is better than single drug.

Objective To investigate the value of nuchal translucency(NT) thickening in the fetal chromosome abnormality screening.Methods The 14 881 pregnant women received NT measurement in 11-13 +6 weeks at Beijing Obstetrics and Gynecology Hospital from January 2010 to August 2012.The 118 fetuses whose NT≥2.5 mm were recruited.One hundred and eight (91.5％,108/118)of them accepted invasive procedure and karyotype analysis.Results (1) Chromosome karyotype analysis:113 singleton pregnancies (95.8％) and 5 twin pregnancies (4.2％) whose NT thickened from 2.5 mm to 11.0 mm were advised karyotype analysis.The 108 pregnant women accepted karyotype analysis.Among them,88 had normal chromosome karyotype,and 20 had chromosome abnormalities.The detection rate was 18.5 ％ (20/108).(2) The sensitivity,specificity,false positive rate,false negative rate,total consistent rate,positive predictive value and negative predictive value of prenatal screening of chromosome abnormalities for NT ≥ 2.5 mm were 44％,99％,1％,56％,99％,19％ and 100％,respectively.(3) Among the 88 fetuses who had normal karyotype,72 (82％) had isolated thickened NT,while 16 (18％) had fetal structural malformation or intrauterine demise.(4) Among the 10 pregnant women who did not accept fetal karyotype analysis,8 terminated pregnancy because of fetal structural malformation,and the other 2 fetuses died in uterus.(5)All of the 5 twin pregnancies were dichorionic twins,and one of the twins had thickened NT.Among the 5 twin pregnancies,one fetus was trisomy 21 and others had normal karyotype.3 twin pregnancies who had normal chromosomes gave live birth.And the other had a gastroschisis and exstrophy deformity fetuse.This fetuse died in uterus and remaining fetuse had full-term live birth.(6) 35 (29.7％) pregnant women received second trimester Down's syndrome serum screening.One was high risk and was proved a trisomy 21 pregnancy.Thirty-four were low risk and had normal chromosome karyotype.Conclusion NT thickening may indicate fetal chromosome abnormalities or other structural malformations.It is a useful prenatal screening indicator.

Objective To investigate the effect of nitric oxide synthase(NOS) inhibitors and L-arginine(L-Arg) on the prognosis of traumatic shock in rats. Methods Traumatic shock models of Sprague-Daulay rats were made and randomly devided into control group (n=24),L-NAME treatment group (n=24),AG treatment group (n=24) and L-Arg treatment group (n=24). Serum nitric oxide(NO) levels and oxygen partial pressure in tissues include skeletal muscles,liver and small intestine were detected at 1h,3h,5h after resuscitation. Meanwhile, hemodynamic data of the rats and their survival rates of 12h and 24h were monitored and recorded. Results Serum NO concentration was statistically lower after resuscitation in L-NAME group than that in control group, while there were no statistical significance of tissues oxygen partial pressure and survival rate in 12、24h between the two groups. AG could decrease serum NO levels only at late stage of traumatic shock,but no effect on the synthesis and relase of NO at early stage of traumati shock.AG could improve tissues oxygen partial pressure of the liver and small intestine, and prolonged the mean survival time. L-Arg could increase serum NO levels, and improve oxygen partial pressure of intestine and significantly increase the survival rate at 12h and 24h in rats with traumatic shock. Conclusions Treatment with AG and L-Arg can improve the prognosis of traumatic shock rats much better than that with L-NAME.

Objective To assay the clinical effect of proximal dorsal digital artery pedicled island flap in treatment and sensory reconstruction of adjacent finger soft-tissue defect.Methods The study enrolled 21 cases of soft-tissue defect in 21 fingers treated from January 2013 to January 2014.All the defects were covered with the proximal dorsal artery pedicled island flaps raised from the adjacent finger.Index finger was injured in 7 patients,middle finger in 9 patients,ring finger in 4 patients,and little finger in 4 patients.Defect and flap dimensions varied from 1.9 cm × 1.5 cm to 4.3 cm × 2.3 cm and from 2.0 cm × 1.7 cm to 4.5 cm × 2.5 cm respectively.Donor site was resurfaced with a fullthickness skin harvested from medial side of the upper arm.Postoperative flap appearance and two-point discrimination were evaluated.Total active motion (TAM) of the finger was evaluated after operation.Results All the flaps and skin grafts survived after operation.Duration of the follow-up was 6-18 months (mean,14.7 months).Through the final follow-up,appearance and function of the flap were satisfactory,donor site healed well,and two-point discrimination was 5-9 mm (mean,6.3 mm).TAM evaluation was excellent in 19 patients and good in 2 patients with the excellent-good rate of 100％.Conclusion The proximal dorsal artery pedicled island flap raised from the adjacent finger is an ideal choice in finger soft-tissue reconstruction,for the technique has advantages of high survival rate,satisfactory appearance and sensory function as well as few complications.

Objective To estimate the excess relative risk coefficients of stomach cancer for Chinese population attributable to ionizing radiation.Methods The excess relative risk and excess absolute risk coefficients of stomach cancer were estimated based on Life Span Study by using risk models developed by BEIR Ⅶ committee (Biological Effect of Ionizing Radiation).Guided by transportation methods from Life Span Study to Americans,we determined that transportation method for Chinese population includes both multiplicative and additive models with a weight of 0.7 and 0.3 respectively,on an arithmetic scale.Besides,curve fitting was used to obtain sex-age-specific stomach cancer baseline incidence based on Chinese cancer annual report.Then,Chinese excess relative risk coefficients of stomach cancer were obtained by substituting excess relative risk,excess absolute risk of Life Span Study and Chinese baseline incidence rate into risk transportation model.Results Excess relative risk coefficients of stomach cancer for Chinese population are 0.26/Sv for male and 0.64/Sv for female,whose exposure age is 30 years old and cancer age is 60 years old.Coefficients increase with decreased exposure age and cancer age.Conclusions Excess relative risk coefficients of stomach cancer for Chinese population are by larger higher than that of Life Span Study,and their sex-age tendency are similar.

Objective To estimate the averaged excess relative risk(ERR) in Chinese population based on the radiogenic cancer risk of leukemia in Japanese atomic bomb survivor cohort,and to discuss proper method suitable for risk transfer between populations.Methods Based on BEIR Ⅶ radiogenic cancer model and population transfer model,and the 2009 Chinese leukemia baseline rates given in 2012 Chinese Cancer Registry Annual Report,comparison was made of population incidences in seveal countries to adjust the weighting factors.Results The ERR of three subtypes of leukemia as a whole was obtained,and the weighting factors for risk transfer model was assumed.The additive factor for male was 0.2,and the multiplicative factor was 0.8,while the additive factor for female was 0.15,and the multiplicative factor was 0.85.Conclusions For the risk transfer between populations,weighting factor was adjusted as a whole to obtain the ERR value for estimating the risk to Chinese population.The risk transfer method suitable for Chinese population was obtained by using the incidence rate available for Chinese population to directly transfer radiation-induced leukemia risk to Chinese from Japanese.

Objective To investigate the value of detecting methylated SEPT9 gene (mSEPT9) in serum and stool in screening colorectal cancer in elderly people.Methods Subjects were divided into three groups, the colorectal cancer group (n=82), the colorectal polyps group (n=80) and the healthy control group (n=100).Real-time quantitative polymerase chain reaction (PCR) was used to detect mSEPT9 in peripheral blood and feces.The relationship between mSEPT9 and clinical and pathological characteristics of colorectal cancer was analyzed.The agreement between serum and stool results was analyzed.Results The positive rate of serum mSEPT9 was 73.2％ in the colorectal cancer group, 6.3％ in the colorectal polyps group and 4.0％ in the healthy control group, with statistical significance between the colorectal cancer group and the other two groups (P＜0.01).The sensitivity and specificity for plasma mSEPT9 detection in screening colorectal cancer were 73.2 ％ and 95.6％, respectively.The positive rate was higher in patients with tumor maximum diameter over 3.0 cm, invasion of the entire serosa layer, lower differentiation or advanced clinical staging (P＜0.05).The detection results of plasma mSEPT9 were in complete agreement with those of stool mSEPT9 from the same patients.Conclusions The expression of mSEPT9 is high in elderly patients with colorectal cancer and has a high sensitivity and specificity for PCR detection.Complete agreement can be seen in results from plasma and feces.Detecting mSEPT9 can be a valuable approach to screening colorectal cancer in the elderly.

ObjectiveTo investigate the relationship between fractional exhaled nitric oxide (FeNO) and bronchopulmonary dysplasia (BPD) in extremely/very low birth weight infant (ELBWI/VLBWI). MethodsThirty-five ELBWI/VLBWI (gestational age <34 weeks at birth and birth weight <1 500 g), who were admitted to neonatal intensive care unit of Peking University Third Hospital from October 2014 to March 2015 with respiratory distress soon after birth, were enrolled into the study, and divided into BPD group (n=11) and non-BPD group 1 (n=24) according to the diagnosis at discharge. One day before they left the hospital, FeNO level was determined with Exhalyzer D, an equipment for pulmonary function test. Difference of FeNO and nitric oxide (NO) production between the two groups was compared witht-test or Fisher exact test, and the value of FeNO in predicting BPD was tested by receiver-operating characteristic (ROC) curve.ResultsThe mean gestational age at birth in BPD group was significantly less than that in non-BPD group [(29.7±1.9) vs (32.0±1.5) weeks,t=4.005,P=0.000], and the duration of invasive ventilation [(53.0±91.3) vs (15.0±30.2) h, t=1.598,P=0.002] and oxygenation was longer [(42.1±7.8) vs (8.2±6.4) d,t=13.567,P=0.000]. There were more babies required surfactant treatment, prenatal cortisone administration, and inhalation of cortisone and bronchodilator during hospital stay in BPD group than in non-BPD group[10/11 vs 38%(9/24), 11/11 vs 58%(14/24) and 11/11 vs 21%(5/24), Fisher exact test, allP<0.05]. The age and body weight of the babies at the time of FeNO determination in BPD group were older or higher than those in non-BPD group [(46.4±16.3) vs (20.9±11.7) d,t=5.278,P=0.000; (2 090±164) vs (1 892±153) g,t=3.498,P=0.001], but the corrected gestational age was similar [(36.3±3.1) vs (35.0±2.3) weeks,t=1.407,P=0.169]. Both the mean FeNO level and NO production in BPD group were significantly higher than those in non-BPD group [(13.6±6.9) vs (8.0±3.6) ppb (1 ppb=1×10-9 mol/L), (25.6±10.1) vs (18.1±9.0) nl/min,t=2.967 and 2.478,P=0.006 and 0.018]. The area under the ROC curve was 0.749 (P=0.021, 95%CI: 0.539-0.953) which implied that FeNO provided medium power for discrimination of ELBWI/VLBWI with BPD from those without, with a sensitivity of 72.7% and specificity of 75.0% at the cut-off value of 11.55 ppb.ConclusionsFeNO and NO production in BPD infants are significantly higher than non-BPD infants. Measurement of FeNO for ELBWI/VLBWI through mask before discharge is a simple, safe and invasive procedure to objectively evaluate pulmonary function early after birth.

Objective This study is to investigate the changes in the NFATc 4/3 signaling pathway in rat hippocampus after whole brain radiation. Methods A total of 120 one?month?old male Sprague?Dawley rats were randomly divided into four groups to receive whole brain radiation using 4?MeV electron beams with doses of 0( control) ,2,10,and 20 Gy,respectively,in a single fraction. At 6 hours,12 hours,1 day,3 days,1 week,and 2 weeks after radiation,Western blot and real?time PCR were used to evaluate the changes in expression levels of CaN, NFATc 4/3, p?NFATc 4/3, and GSK?3β. Results There were no significant changes in the expression of NFATc 4/3 or p?NFATc 4/3 at 6 and 12 hours after whole brain radiation. At 1 day after radiation,compared with the control group,the expression of p?NFATc 4/3 in the radiation groups was significantly increased in a dose?dependent manner ( 2 Gy:P= 0. 014;10 Gy:P=0. 011;20 Gy:P=0. 000 );however, there was no significant difference in the expression of NFATc 4/3 between the radiation group and the control group. The expression of NFATc 4/3 was significantly decreased in the radiation groups than in the control group at day 3 ( 2 Gy:P=0. 040;10 Gy:P=0. 000;20 Gy:P=0. 000),1 week (2 Gy:P=0. 692;10 Gy:P=0. 032;20 Gy:P=0. 021),and 2 weeks (2 Gy:P=0. 001;10 Gy:P=0. 000;20 Gy:P=0. 000) after radiation,while there was no significant difference in the expression of p?NFATc 4/3 between any two groups. There were no time?or dose?dependent changes in expression of CaN or GSK?3β. Conclusions Ionization radiation has an inhibitory effect on the NFATc 4/3 signaling pathway in rat hippocampus. Combined with our previous results,this study suggests that radiation?induced cognitive dysfunction is associated with the NFATc 4/3 signaling pathway.
