Objective: To investigate the cognitive impairment features in patients with amnestic mild cognitive impairment(aMCI) and vascular cognitive impairment-no dementia(VCI-ND).Methods:Sixteen normal elders,10 patients with aMCI and 12 patients with VCI-ND were recruited.The normal elders were selected from communities in Shanghai,while the aMCI and VCI-ND patients were selected from outpatient clinic.All participants ranged in age of 50～80 years,with education level of junior middle school or above,and they completed cranial CT or MRI and a series of neuropsychological tests.Results:In the three memory tests,aMCI group performed worst.The scores of both aMCI and VCI-ND groups were lower than that of the normal elders.For example,the delayed recall scores of the Rey-Osterrich complex figure test in the three groups were(18.8?9.5)(normal),(5.6?5.6)(aMCI) and(9.6?7.0)(VCI-ND)(P

Objectives To provide prenatal diagnosis and genetic counseling for four athigh-risk pregnant women with a suspected family or personal history of fragile X syndrome (FXS) by genetic screening of fragile X mental retardation (FMR1) gene.Methods This study was conducted on four pregnant women (No.l to 4) who received outpatient treatment in Peking University First Hospital from August 2014 to June 2016.Genomic DNA was extracted from peripheral blood samples of the pregnant women and six of their family members,four of which were suspected or confirmed FXS and the other two were FMR1 gene carriers.Amplide X kits were used to detect CGG repeat size in FMR1 gene.Two amniocytes and one chorionic villi samples were collected from three pregnant women to extract DNAs for FMR1 gene and karyotyping analyses.Results There were patients diagnosed with FXS in all the families by detecting CGG repeat numbers in FMR1 gene.The pregnant woman No.1 was a permutation carrier;No.2 carried normal FMR1 alleles while her brother had a mutation with over 20 CGG repeats in FMRI gene at chromosome X.No.3 and 4 were full mutation carriers with over 200 CGG repeats in FMR1 gene.After genetic counseling,No.3 decided to terminate the pregnancy due to abnormal fetal karyotype (47,XY,+21) and full mutation of FMR1 alleles.No.1 and 4 continued to pregnancy as their fetuses were normal in FMR1 alleles and karyotype.No.2 continued to pregnancy as her fetus was free of FXS risk.Conclusions Prenatal diagnosis and genetic counseling should be conducted on women at highrisk for FXS to avoid birth defects.People with a family history of FXS should be tested for FMR1 gene carrier status.

OBJECTIVETo observe the clinical efficacy of Wangbi Tablet (WT) on the treatment of knee osteoarthritis (KOA), and to study its treatment program by integrative medicine.

METHODSThe randomized, parallel control, and multi-center clinical observation method was used. 160 KOA patients of Gan-Shen deficiency complicated with stasis-blood blockade syndrome were assigned to three groups. Group A (72 cases) was treated by WT, Group B (42 cases) was treated by Votalin Tablet, and Group C (46 cases) was treated by WT + Votalin Tablet. All patients were treated for two months. Before and after treatment the clinical symptoms, the knee function activity, adverse reactions were observed and recorded. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) of each patient were respectively detected, statistically analyzed and compared.

RESULTSAfter eight weeks of treatment significant difference was shown in the time of morning stiffness in joints, joint tendemess, swelling, pain, joint functional activities, ESR, and CRP between Group A and Group B (P<0.01). Besides, better effects were obtained in Group C (P<0.01). Improvement of ESR and CRP: They were obviously improved in the three groups after treatment (P<0.01). As for the markedly effective rate, better effects were obtained in Group C (P<0.05).

CONCLUSIONSIn the treatment of KOA, WT showed favorable effects with no obvious adverse reaction. The combination of WT and Voltaren Tablet was significantly superior to use of WT or Votalin Tablet alone. It could reduce the dosage of Voltaren Tablet and avoid adverse reactions of the gastrointestinal tract.

Based on the transcriptome data, we cloned the open reading frame of IiHCT gene from Isatis indigotica, and then performed bioinformatic analysis of the sequence. Further, we detected expression pattern in specific organs and hairy roots treated methyl jasmonate( MeJA) by RT-PCR. The IiHCT gene contains a 1 290 bp open reading frame( ORF) encoding a polypeptide of 430 amino acids. The predicted isoelectric point( pI) was 5.7, a calculated molecular weight was about 47.68 kDa. IiHCT was mainly expressed in stem and undetectable in young root, leaf and flower bud. After the treatment of MeJA, the relative expression level of IiHCT increased rapidly. The expression level of IiHCT was the highest at 4 h and maintained two fold to control during 24 h. In this study, cloning of IiHCT laid the foundation for illustrating the biosynthesis mechanism of phenylpropanoids in I. indigotica.

The benefit achieved by concurrent chemoradiotherapy (CCR) and sequential chemoradiotherapy (SCR) vs radiotherapy (RT) alone for patients with stage II-IVa nasopharyngeal carcinoma (NPC) was compared. A total of 113 patients with stage II-IV a NPC were allotted into CCR group (n=38), SCR group (n=36) and RT alone group (n=39). All patients were irradiated with the same RT technique to ≥66 Gy at 2 Gy per fraction, conventional 5 fractions/week in all groups. The CCR group received concurrent chemotherapy of weekly cisplatin for 7 weeks, and the SCR group received neoadjuvant and (or) adjuvant chemotherapy. The results showed that the 3- and 5-year overall survival rate was significantly higher in CCR group than in RT alone group (92.16% vs 61.54%, 81.58% vs 51.28%, P<0.005). The median survival time was significantly longer in CCR group than in RT alone group (67.8 months vs 52.7 months, P<0.005). It was concluded that CCR could significantly improve overall survival rate, progression-free survival rate, and median survival time when compared with RT alone.

Objective To evaluate the effects of different doses of lidocaine on suppressing fentanyl-induced cough and determine a safe suppressing dose.Methods Two hundred patients undergoing general anesthesia were randomized to four groups evenly.The following medications were given within ten seconds:normal saline 10ml (groupⅠ,control group),lidocaine 1 mg/kg (groupⅡ),lidoeaine 1.5 mg/kg(groupⅢ),lidocaine 2mg/kg (groupⅣ).Toxic symptoms of lidocaine were recorded within lmin after the administration of lidocaine,then fentanyl 3?g/ kg was given intravenously within 5 seconds.Cough incidence and cough grade were recorded within 2rain after the administration of fentanyl.Systolic blood pressure (SBP),diastolic blood pressure (DBP),heart rates (HR),and satu- ration of pulse oximeter(SpO2) were recorded during different time points of induction,all recorded data were anal- ysed by the statistical software,P value

This study is to find out the induction by sodium nitrite of epithelial-mesenchymal transition (EMT) in human hepatocellular carcinoma cells, SMMC-7721. After treatment of SMMC-7721 with 0.25 - 25 mmol.L-1 sodium nitrite for 48 h, the assays used include enzyme-linked immunosorbent assay (ELISA) for evaluation of TGF-beta1, IL-6 and IL-8 level in the conditioned medium, phase-contrast microscopy for morphology observation, and scratch wound healing as well as transwell migration assays for measurement of migration and metastatic potential. Additionally, the hallmarks of EMT, p-AKT and its downstream signaling molecules were examined by Western blotting. The results showed that TGF-beta1 secreted by SMMC-7721 elevated significantly in a dose-dependent fashion, whereas the increased IL-8 and IL-6 did not show dose-dependent response. The EMT was induced by exposure of SMMC-7721 with 0.25 mmol.L-1 of sodium nitrite, which was characterized by increased level of Vimentin, decreased E-cadherin and elevated activity of migration and metastatic potential. The results suggest that sodium nitrite could induce SMMC-7721 EMT by increased secretion of TGF-beta1 and IL-8.

OBJECTIVETo observe the clinical effects of Biqi Capsule (BQC) combined with methotrexate (MTX) for treatment of rheumatoid arthritis (RA), and to study an effective protocol of RA treated by integrative medicine.

METHODSOne hundred and thirty-eight patients with RA were randomly assigned to Group I (44 cases, treated by BQC), Group II (46 cases, treated by MTX), and Group III (48 cases, treated by BQC combined with MTX). The therapeutic course for each group was 12 weeks. The degree of joint pain, the tender joint number, the tender joint index, the swollen joint number, the swollen joint index, the two-hand grip, the morning stiffness time, and related laboratory indices were observed in each group before and after treatment. The adverse reactions were recorded.

RESULTSCompared with before treatment, there was statistical difference in the degree of joint pain, the tender joint number, the tender joint index, the swollen joint number, the swollen joint index, the two-hand grip, the morning stiffness time, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and rheumatoid factor (RF) in the 3 groups (P < 0.05, P < 0.01). Besides, better results were obtained in Group III (P < 0.01). As for the inter-group therapeutic efficacy, better results were obtained in Group III (P < 0.01). The gastrointestinal discomfort was the only adverse reaction in the 3 groups. No treatment was given due to its milder symptoms without any effects on the treatment.

CONCLUSIONSBQC showed favorable effects on treating RA with no obvious adverse reaction. BQC combined with MTX showed better clinical efficacy than use of BQC or MTX alone. It could reduce the adverse reactions of MTX. BQC combined with MTX could reduce the toxic reactions and enhance the therapeutic effects, indicating it was an effective treatment program for RA.

Human osteosarcoma MG-63 cells were induced into differentiation by 5 mmol/L hexamethylene bisacetamide (HMBA). Their nuclear matrix proteins (NMPs) were selectively extracted and subjected to two-dimensional gel electrophoresis analysis.The results of protein patterns were analyzed by Melanie software. The spots of differentially expressed NMPs were excised and subjected to in situ digestion with trypsin. The maps of peptide mass fingerprinting were obtained by MALDI-TOFMS analysis, and were submitted for NCBI database searches by Mascot tool.There were twelve spots changed remarkably during the differentiation induced by HMBA, nine of which were identified. The roles of the regulated proteins during the MG-63 differentiation were analyzed. This study suggests that the induced differentiation of cancer cells is accompanied by the changes of NMPs, and confirms the presence of some specific NMPs related to the cancer cell proliferation and differentiation. The changed NMPs are potential markers for cancer diagnosis or targets for cancer therapy.
