Methods 100 patients with allergic rhinitis from lishui people's hospital from January 2014 to January 2016 were divided into two groups,with 50 cases in each group.The control group was treated with nasal spray, and observation group was treated with Yupingwind particles combing with nasal spray. Relevant indicators were analyzed between two groups. Results Recent curative effect in observation group was 92.00%,higher than control group with 76.00%(P<0.05).After treatment,Symptom score,immune factors and inflammation level in observation group were better than those in control group(all P<0.05).Conclusion Yupingwind particles can improve recent curative effect for patients with allergic rhinitis.

Objective; To study estrogen receptor gene Xbal and Pvu Ⅱ polymorphisms in patients with aggressive periodontitis (AgP). Methods; Xbal and Pvu Ⅱ DNA was extracted by Chelex-100 and amplified by PCR from buccal swabs of 48 cases of AgP patients and 60 normal controls. The PCR products were analyzed by polymerase chain reaction linked fragment length polymorphism (PCR-RFLP) assay. Results: There were significant differences of the distribution of Xba I genotype between AgP group and control group, female AgP group and female control group, male AgP group and male control group(P<0.05). There was no difference of Pvu D genotype distribution between patient group and control group (P>0.05). Multivariate Logistic Regression Analysis showed that male group was less susceptible to AgP than female group(OR =0. 352), the older was less susceptible to AgP than the younger(OR =0.950), and the xxXx genotype was less susceptible to AgP than XX genotype [OR(Xx) =0.224, OR(xx) = 0.678). Conclusion: Specific relationship is found between the susceptibility of AgP and the ER gene-Xbal polymorphism. People with XX genotype is more susceptive to AgP than xx, Xx genotypes.

Objective To observe the therapeutic effect of Di'ao Xinxuekang (DAXXK) on myocardial ischemia-reperfusion injury in rats, and to explore its mechanisms. Methods The myocardial ischemia-reperfusion injury model was established by the ligation of descending coronary artery in rats. Then animals after the modeling were randomized into model group, DAXXK-d (31.5 mg/kg) group, DAXXK-g (63.0 mg/kg) group and Diltiazem (24.8 mg/kg) group. A separate sham group was used as control. The treatment group was given DAXXK once a day for 7 days. Cardiac function and cardiac configuration were measured by color Doppler ultrasound diagnostic method. Hemodynamics was measured by Millar catheter method. The arterial oxygen saturation and blood oxygen pressure were measured by i-STAT 300 blood gas analyzer. Inflammatory cytokines interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, adhesion molecules VCAM-1, ICAM-1, and apoptosis-related protein Bcl-2, Bax were detected by ELISA. Myocardial apoptosis was measured using TUNEL method. Results Compared with model group, the left ventricular fractional shortening (FS), the systolic and diastolic function were improved, and the left ventricular pressure maximum rise/ fall rates (± LVdp/dtmax) were increased, in DAXXK group. DAXXK improved lung function, increased arterial oxygen pressure and oxygen content. The inflammatory cytokines IL-1β, IL-6, TNF-α and adhesion molecules ICAM-1 and VCAM-1 were decreased in DAXXK group. The myocardial swelling and inflammatory infiltration were relieved, myocardial apoptosis was reduced, the expression of Bcl-2 protein was increased and the expression of Bax protein was decreased in DAXXK group. Conclusion DAXXK can protect myocardial ischemia-reperfusion injury, which involved in the inhibition of apoptosis and reduction of inflammatory cytokines.

Dietary fiber contents in 34 common foods perchased in Beijing markets have been determined with detergent method, including neutral detergent fiber, acid detergent fiber, cellulose, hemicellulose and lignin. On dry basis, the dietary fiber contents of vegetables varied with kinds of food: the dietary fiber contents were higher in tender stems, leaves, stalks and flowers; lower in starchy tubers and roots; medium in non-starchy tubers and roots. The propotions of dietary fiber components were different in various categories of foods. Cellulose was the major component in vegetables and legumes, but in most cereals, hemicellulose content was higher than cellulose. All foods had the lowest lignin content with the exception of garlic bolt.

Objective To investigate the postoperative complication and nursing experience of hand-assisted laparoscopic J-type ileal pouch-anal anastomosis (IPAA) in familial adenomatous polyposis (FAP). Methods A total of 36 patients with FAP who had undergone hand-assisted laparoscopic J-type ileal pouch- anal anastomosis (IPAA) were analyzed retrospectively. Results The postoperative complication included ileal pouch bleeding in 2 cases, urinary retention in 3 female patients, external hemorrhoids swelling in 3 cases, and anastomotic fistula in 2 cases. Six cases had ileum pouch inflammation during the postoperative follow- up. All the complications were relieved after conservative medical therapy. Conclusions IPAA operation puts forward high technical requirements with more postoperative complications. Therefore, it is important to strengthen nursing of the patients, reduce postoperative complication and increase quality of life of FAP.

Objective To explore the effect of comprehensive rehabilitation combined with self- efficacy training on hemiplegics after stroke. Methods 60 ischemic stroke patients following hemiplegia were divided into three groups: control group 1 (n=20), control group 2 (n=20), and experiment group (n=20). All the patients received routine rehabilitation, the control group 2 received tasks analysis approach,and the experiment group received tasks analysis approach and self-efficacy training. All the patients were evaluated by Fugl-Meyer Assessment (FMA), Berg Balance Scale (BBS), Self- rating Depression Scale (SDS), Self- rating Anxiety Scale (SAS), modified Barthel Index (MBI) and General Self-efficacy Scale (GSES) before and 8 weeks after treatment. Results The scores of FMA, BBS, SDS, SAS, MBI and GSES improved significantly in the experiment group than in the control group 1 and the control group 2 after treatment (P<0.05). Conclusion Comprehensive rehabilitation combined with self-efficacy training can improve the ability of mood and motion, and the activities of daily living of ischemic stroke patient with hemiplegia.

Objective To investigate the radiobiological effects of VPA-BSANPs on C6 and U87 glioma cells in vitro.Methods C6 and U87 glioma cells were treated with different concentrations of VPA and VPA-BSANPs for 12 h and 24 h,and MTT assay was used to determine cell viability.C6 and U87 cells were treated with different concentrations of VPA and VPA-BSANPs conbined with X-ray irradiation (0,2,4,6,and 8 Gy),and colony formation assay was used to determine plating efficiency (PE).C6 and U87 glioma cells were treated with different concentrations of VPA and VPA-BSANPs for 12 h,followed by X-ray irradiation (0,4,and 8 Gy),and flow cytometry using Annexin V-FITC/PI staining was used to examine cell apoptosis.Western blot was used to evaluate the effects of VPA and VPA-BSANPs on radiation-induced apoptosis protein expression.One-way ANOVA was used for comparison of means with homogeneity of variance between multiple groups,and the t-test was used for comparison of means between two groups.Results Without irradiation,VPA and VPA-BSANPs had no significant inhibitory effects on the proliferation of C6 and U87 cells (P=0.328,0.920).The PE of cells treated with VPA-BSANPs combined with irradiation was significantly lower than that of cells treated with VPA combined with irradiation (P=0.000).In C6 and U87 cells,VPA-BSANPs combined with irradiation increased the expression of p53 and Bax (P =0.000,0.000 and P =0.010,0.002),but reduced the expression of Bcl-2 (P =0.008,0.000).Active caspase-3 fragments were only found in the cells treated with VPA-BSANPs combined with irradiation and VPA combined with irradiation,but were less in the former cells than in the latter cells (P=0.004).The active fragments of peroxisome proliferator-activated receptor were only found in the cells treated with VPA-BSANPs combined with irradiation.Conclusions VPA-BSANPs can increase the radiosensitivity of C6 and U87 glioma cells in vitro,possibly by promoting the apoptosis of tumor cells induced by radiation.

Objective To assess the diagnostic value of 3D-enhanced T2 ? weighted angiography (ESWAN )in evaluating superficial siderosis of the central nervous system (SS-CNS)after traumatic subarachnoid hemorrhage (tSAH).Methods ESWAN and GRE T2 ? WI sequence were performed on 30 patients with tSAH,detection rate and the number of distribution areas of SS-CNS were compared between the two sequences.A McNemar’s test and Wilcoxon signed-rank test were used to analyze the differences between T2 ? WI and ESWAN images sequences. Results In the tSAH group,29 of 30 patients (96.7%)showed SS-CNS on ESWAN images,the total number of SS-CNS regions was 134.Identified SS-CNS positive rate respectively was 95.8% (23/24)on ESWAN images and 66.7% (1 6/24)on T2 ? WI in 24 patients simultaneously perform ESWAN and T2 ? WI sequences.A McNemar ’s test showed that there was significant difference between the positive rates of two sequences in detecting the SS-CNS (χ2 =7.0,P <0.05).The number of SS-CNS regions on ESWAN images and T2 ? WI was 106 and 34 respectively.The Wilcoxon signed rank test showed that the number of SS-CNS regions difference between two sequences was significant (Z =-4.225,P <0.01).Conclusion Various degress of SS-CNS are detected in a majority of tSAH atients.ESWAN sequence is a reliable and efficient method for assessment of SS-CNS.

Objective:To explore the feasibility of dual-energy CT (DECT) in the evaluation of liver iodine concentration in patients on long-term oral amiodarone treatment (≥12 months).Methods:Eighteen subjects undergoing abdominal dual-energy CT who met the criterion in January 2017 were collected as a control group. Twenty-seven patients who received oral amiodarone treatment for more than 12 months from January 2017 to May 2019 were enrolled as an experimental group. The difference of CT value and iodine concentration of liver, pancreas and spleen in 140 kV, 100 kV and VNC images between experimental and control groups were measured and analyzed. The correlation between liver CT value and liver iodine concentration was analyzed by Spearman correlation.Results:The concentrations of iodine in the liver, pancreas and spleen of the experimental group were 0.2 (0.2, 0.4), 0.1 (0.1, 0.2) and 0.2 (0.1, 0.2) mg/ml, and those in the control group were 0.2 (0.1， 0.2), 0.1 (0.1, 0.2) and 0.1 (0.1, 0.2) mg/ml. The difference in the concentration of iodine of the liver was statistically significant ( Z=-3.354, P<0.05), however there was no significant difference in the concentration of pancreas and spleen between the two groups ( Z=-0.179 and -1.590, P>0.05). The CT values of 100 kV, 140 kV, VNC images in the experimental group [(74±18)， (70±10) and (71±5) HU] were higher than those in the control group [(60±6)， (59±6) and (62±6) HU], and the differences were statistically significant ( t=3.310, 4.205 and 5.241, P<0.05). There was a positive correlation between the CT value of 140 kV image and iodine concentration ( r=0.410, P<0.05). In the experimental group, the time difference of taking amiodarone was statistically significant ( P<0.05). Conclusions:DECT can be used to quantitatively measure the liver iodine concentration of patients with long-term oral amiodarone, and provides some biological indicators for the assessment of amiodarone induced liver injury.

Objective To investigate proteolipid protein 1 (PLP1) mutations in six pedigrees with Pelizaeus-Merzbacher disease (PMD),and to provide prenatal consulting and prenatal diagnosis.Methods Subjects were six probands with PMD admitted in Department of Pediatrics,Peking University First Hospital from July 2006 to November 2011 and their family members.Genomic DNA sarnples were extracted from peripheral bloods of probands and their family members.Multiplex ligation-dependent probe amplification (MLPA) technique was used to detect PLP1 duplication mutation.Direct DNA sequencing was used to detect point mutation.Genetic diagnosis were based on PLP1 mutation genotype from probands.Prenatal diagnosis of nine fetuses were performed from seven PLP1 mutation female carriers by fetuses' DNA extracted from amniocytes or villus cells.Results PLP1 duplications were found in probands 1-4 (P1-4) whose mothers and the aunt of proband 1 (P1) were PLP1 duplications carriers.The two cases of point mutation,c.96C＞G(p.F32L) and c.623G＞T (p.G208V),were found in proband 5 (P5) and proband 6 (P6).Hcterozygous changes of the same mutations were found in P5' and P6' mothers with normal phenotypes.Seven female PLP1 mutation carriers were pregnant again.Prenatal diagnosis of PLP1 for nine fetuses presented one PLP1 duplication,one point mutation,one PLP1 duplication carrier,and six wildtypes.A segmental crossing over of X chromosome was detected in one male fetus of PLP1 wildtype.Conclusions PLP1 mutation analysis could help to diagnose PMD pedigree and to identify female PLP1 mutation carrier in the family.The following prenatal diagnosis and proper genetic counseling are very important to prevent PMD child from being delivered.
