ObjectiveTo investigate the clinical efficacy of Huangqi injection combined with Buzhong Yiqi acupuncture in the treatment of chronic fatigue syndrome （CFS） with Qi deficiency and its effects on TCM syndromes， fatigue symptoms， serum superoxide dismutase （SOD）， malondialdehyde （MDA）， and oxidized low-density lipoprotein （ox-LDL） levels. MethodA total of 200 patients with CFS of Qi deficiency were randomly divided into a control group （100 cases） and an observation group （100 cases）. The control group was treated with vitamin B compounds， and the observation group was treated with Huangqi injection combined with Buzhong Yiqi acupuncture for two weeks. The scores of TCM syndromes， fatigue symptoms， levels of serum SOD， MDA， and ox-LDL and the incidence of adverse reactions were observed and compared before and after treatment in two groups. ResultAfter treatment， the total effective rate of the control group was 54.34% （50/92）， while that of the observation group was 88.54% （85/96）. The total effective rate of the observation group was higher than that of the control group （χ²=27.13，P<0.05）. Compared with those in the two groups before treatment， scores of fatigue self-assessment scale （FSAS）， physical fatigue and mental fatigue， and sleep/rest response scores of fatigue in the two groups after treatment were significantly decreased （P<0.05）. After treatment， scores of FSAS， physical fatigue and mental fatigue， and sleep/rest response scores of fatigue in the observation group were significantly decreased compared with those in the control group （P<0.05）. Compared with those in the two groups before treatment， TCM syndrome scores in the two groups after treatment were significantly decreased （P<0.05）. After treatment， TCM syndrome scores in the observation group were significantly decreased compared with those in the control group （P<0.05）. Compared with those in the two groups before treatment， MDA levels in the two groups were significantly decreased （P<0.05）， ox-LDL levels in the observation group were significantly decreased （P<0.05）， and SOD levels were significantly increased （P<0.05）. After treatment， compared with those in the control group， the serum MDA and ox-LDL levels in the observation group were significantly decreased （P<0.05）， and the serum SOD was significantly increased （P<0.05）. No serious adverse events or adverse reactions occurred during this clinical trial. ConclusionHuangqi injection combined with Buzhong Yiqi acupuncture has a good clinical curative effect in the treatment of CFS with Qi deficiency， which can effectively improve the fatigue symptoms of patients， increase the level of SOD， and reduce the level of serum MDA and ox-LDL. It is related to the production of antioxidants， inhibiting the production of lipid peroxides， and improving the body's ability to resist oxidative stress.

BACKGROUND: The use of allograft tendon promotes the development of anterior cruciate ligament reconstruction, which is of great importance in the relevant basic research and clinical practice. OBJECTIVE: To summarize the current application and progress of allograft tendon in the anterior cruciate ligament reconstruction. METHODS: We searched relevant articles about the use of allograft tendon in PubMed and Embase published from January 2012 to February 2018 using the keywords of "allograft tends OR allografts, intra-articular knee ligament OR anterior cruciate ligament OR ACL". RESULTS AND CONCLUSION: China's use of allogeneic tendon in the reconstruction of the anterior cruciate ligament is still in the developmental stage. The current pros and cons of using allografts or autografts in anterior cruciate ligament reconstruction are inconclusive. Concerns about the choice of allografts are mainly due to possible infections and slow healing. A huge difference exists in different trials concerning the effects of allografts versus autografts. The conclusions are therefore roughly as follows: there is no difference in knee function after implantation of the two grafts, or the knee joint function is better after autograft. Studies have shown that allografts may increase the risk of secondary surgery. Therefore, the use of allograft tendon faces many clinical challenges in the anterior cruciate ligament reconstruction.

OBJECTIVETo explore the molecular basis for an individual with CisAB subtype of the ABO blood group.

METHODSABO antigen and serum antibody of the proband were detected with a serological method. Exons 5 to 7 of the ABO gene were amplified with PCR and sequenced bidirectionally. Allele-specific amplification for exon 6 to 7 was also carried out.

RESULTSThe proband was assigned as a CisAB phenotype based on his serological characteristics. Heterozygous variations including 220C/T, 261G/del, 297A/G, 467C/T, 646A/T, 681A/G, 771C/T, 803G/C, 829A/G and 1009A/G of the ABO gene were identified through direct sequencing, which was assigned as CisAB01var/O02 genotype. Allele-specific amplification indicated that the proband carried an O02 allele and a CisAB01var allele. Compared with A102, the CisAB01var allele has two nucleotide substitutions at 803G>C and 1009A>G, which resulted in replacement of amino acid Gly by Ala at position 268 and Arg by Gly at position 337.

CONCLUSIONThe CisAB subtype was identified with 803G>C and 1009A>G variants in the α1,3-N-acetyl-galactosaminyltransferase gene compared with that of the A102 allele.

Objective To explore the protective effects of dipeptidyl peptidase-4 inhibitor (DPP-4I) on AD-like neurodegenerative changes and its mechanism. Methods The human neuroblastoma cell line SH-SY5Y on the logarithmic phase was divided into six groups:control group (CON group, treated with PBS contained 1‰DMSO for 12 h), wortmannin intervention group (W group, treated with 0.03 μmol/L wortmannin for 12 h), DPP-4I intervention group (DPP-4I group, treated with 10μmol/L DPP-4I for 12 h), both DPP-4I and wortmannin intervention group (DPP-4I+W group, pre-treated with 10 μmol/L DPP-4I for 2 h, then 0.03 μmol/L wortmannin for 12 h), DPP-4I, wortmannin and Ex9-39 intervention group (DPP-4I+W+Ex9-39 group, pre-treated with 10μmol/L Ex9-39 for 2 h, then 10μmol/L DPP-4I for 2 h followed by 0.03μmol/L wortmannin for 12 h), and Ex9-39 intervention group (Ex9-39 group, treated with 10μmol/L Ex9-39 for 12 h). MTT assay was used to detect the cell vitality. Western blot assay was used to detect the level of total tau protein (tau-5) and phosphorylated tau at different sites (pSpS199/202, pT231 and pS396), the level of phosphorylated neurofilaments (NF-H, NF-M) and phosphorylation of critical enzyme in PI3K/Akt/GSK-3β signaling pathway. Results (1) The cell vitality decreased, the levels of pSpS199/202, pT231, pS396 and NF-H/M increased significantly in W group than those in CON group. However, comparing with CON group, the above mentioned parameters reversed in DPP-4I group. Comparing with W group, the cell vitality increased and phosphorylated levels of above mentioned indices were decreased in DPP-4I+W group. (2) The cell vitality showed a decline trend while the levels of phosphorylation tau at three different sites and NF-H/M were higher in Ex9-39 group than those in CON group. Comparing with DPP-4I+W group, the results of the phosphorylated levels showed the same changes in DPP-4I+W+Ex9-39 group. (3) Comparing with CON group, the expression levels of phosphorylated PI3K, Akt and GSK3β increased significantly in DPP-4I group, while those decreased in W group. Additionally, the expression levels of phosphorylated PI3K, Akt and GSK3β were significantly increased in DPP-4I+W group than those in W group. Conclusion DPP-4I can enhance the level of GLP-1 and activate PI3K/Akt/GSK-3βinsulin signaling pathway to improve the hyperphosphorylated tau and NFs induced by wortmannin, and to protect AD-like neurodegeneration.

Objective:To determine the reliability and validity of the Chinese version of Fagerstrom Test for Nicotine Dependence (FrND) scale among smoking male inpatients with schizophrenia.Methods:Two hundred and twenty smoking male inpatients,who met criteria for schizophrenia of Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition (DSM-Ⅳ),were consecutively included.FTND scale and Russell's Reasons for Smoking Questionnaire (RRSQ) were used to assess subjects'severity of nicotine dependence and addiction score of the dimension of reason for smoking,respectively.According to the principle of voluntariness,37 subjects were selected and re-assessed with FTND scale after two-week interval.Reliability,correlation and factor analyses were used to examine the reliability and validity.Results:The Cronbach α (internal consistency) and two-week re-test reliability coefficients of FTND scale were 0.68 and 0.72 (P ＜0.01),respectively.The criterion related validity coefficient with addiction score of RRSQ was 0.53 (P ＜0.01).Two common factors were abstracted from the scale factor analysis,accounting for 52.4％ of the total variance.There were statistically significant differences between patients with different duration of illness,number of hospitalizations and age of smoking initiation (P ＜0.05).Conclusion:The Chinese version of FTND scale for smoking male inpatients with schizophrenia has a relatively low internal consistency and good re-test reliability,criterion related validity,construct validity and empirical validity.

BACKGROUND:Dihydroartmisinin can promote apoptosis of glioma cels GL261, but its effect on glioma stem cels is stil unknown. OBJECTIVE:To investigate the preliminary mechanism that dihydroartemisinin inhibits migration and invasion of glioma stem cels. METHODS: Glioma stem cels were isolated from mouse malignant glioma cel lines GL261. Immunofluorescence analysis was conducted to identify the characteristics of glioma stem cels. Migration and invasion abilities of glioma stem cels were analyzed by Transwel assay. The mRNA expressions of Tol-like receptor 2, matrix metaloproteinase-2 and matrix metaloproteinase-9 were examined by real-time fluorescence quantitative PCR. RESULTS AND CONCLUSION:The characteristics of glioma stem cels were identified by CD133 and Nestin staining. The migration and invasion of glioma stem cels were attenuated by dihydroartemisinin dose-dependently. Moreover, the mRNA expression of Tol-like receptor 2, matrix metaloproteinase-2 and matrix metaloproteinase-9 was also decreased by dihydroartemisinin in a dose dependent manner. These results suggest that dihydroartemisinin inhibits the migration and invasion of glioma stem cels probably through attenuation of Tol-like receptor signaling pathway.

Objective To systematically evaluate, after subcutaneous injection of low-molecular-weight-heparin( LMWH) , the effect of whether pressing or not on bruising. Methods All controlled clinical trails about pressing duration after subcutaneous injection of LMWH were collected by searching Cochrane Library (CENTRAL), PubMed, EMbase, CNKI, and Chinese Biomedical Literature Database (CBM). Two researchers, working independently, extracted strictly and assessed the data by the bias risk evaluation tool of the Cochrane collaboration network, with the data combined and analyzed by RevMan 5. 3 software. Results Nine clinical controlled trials that were all Chinese literatures were included, in which 2 814 injections were reported in total in the pressing group while 2 801 ones in non-pressing group. It was shown in Meta analysis that for severe subcutaneous bleeding, RR=0.7, 95% CI(0.49-0.99), (P<0.05); subgroup analysis revealed that evaluation criterion of the outcome indicators was the sources of heterogeneity among the included studies, and the results supported the positive effect of not pressing. Conclusions Pressing duration has an impact on bruising after subcutaneous LMWH injections. No pressing after injection does not increase the incidence rate of local moderate or severe subcutaneous bleeding.
