Objective To explore the impact of the variable number of tandem repeats of monoamine oxidase A gene (MAOA-uVNTR) on the intensity of brain activation during the recognition of facial expression in patients with depression and healthy controls.Methods 28 cases of depression,as well as 33 healthy controls who were matched in gender, age and years of education were divided into different genotypes with the methods of polymerase chain reaction (PCR) amplification and 1.5% agarose gel electrophoresis separation.61 cases were scanned to compare the intensity of brain activation in the recognition of happy, sad and neutral facial expression.Results In healthy controls,cases with high-activity genotype showed increased activation in left cuneus,left inferior frontal gyrus, right medial frontal gyrus and left inferior parietal lobule in comparision with carriers of low-activity genotype.In the depressed, compared with patients with low-activity genotype, cases with high-activity genotype decreased activation in bilateral putamen, left postcentral gyrus, left fusiform gyrus, right superior temporal gyrus and right thalamus.Conclusion Healthy controls with high-activity genotype shows the trend of priority for the identification of negative emotion,this genotype may be one of the risk factors for normal people suffering from depression.Patients with high-activity genotype is associated with the inhibitory of positive emotional state, this may attribute partly to the emotional symptoms in such kind of patients more serious.

Objective To study the immune regulation of antisense peptide in rats by observing immune function of activity fragments of thyrotropin receptor (TSHR) and their corresponding antisense peptides. Methods TSHR peptides TR1, TR2, TR3 and their antisense peptides RT1, RT2, RT3, and three pairs of complementary peptides were injected into rats of different groups respectively, and the serum levels of TT_3, TT_4, TSHR antibody (TRAb), thyroid stimmulating antibody, thyroid blocking antibody and TSH antibody (TSHAb) and pathological changes in thyroid tissue were investigated. Results Serum TRAb could be induced when each of three fragments of TSHR was injected into rats; TRAb and TSHAb were induced by RT1 or RT2; epithelial hyperplasia and lymphocytic infiltration observed in thyroid tissue of rats injected with TR2 could be abated by injecting RT2 subsequently. Conclusion The results suggest that all 3 TSHR fragments are shown to be immunogenic and are capable to induce TRAb; both RT1 and RT2 show their effect on immune regulation and are idiotypic of TSHR peptides; On the other hand, the humoural and cell immunities are ameliarated by injection of antisense peptides. Therefore, it is possible that antisense peptides may be involved in immune regulation via immune network.

OBJECTIVE: To evaluate the safety and efficacy of FK506-based dual therapy and CsA-based triple therapy for immunosuppression after liver transplantation. METHODS: The literature about the randomized controlled trials (RCT) on FK506 and CsA for immunosuppression after liver transplantation was retrieved for analysis using RevMan 5.0 software. RESULTS: A total of 7 RCTs were included; 3 were considered as high quality of RCT, 4 as moderate quality. The results of Meta-analysis of FK506-based dual therapy indicated the patients’ survival rate (RR=1.06, 95%CI=0.77～1.45,P=0.72), grafts’ survival rate (RR=0.99, 95%CI=0.76～1.29,P=0.92), infection rate(RR=0.98, 95%CI=0.60～1.58,P=0.93)and incidence of neurotoxicity (RR=0.59, 95%CI=0.32～1.07,P=0.08)was not significantly different. The incidence of acute rejection in CsA group was lower than in FK506 group (RR=1.57, 95%CI=1.23～2.01,P=0.000 3). CONCLUSION: The curative efficacy of FK506 group is not different from that of CsA group in respect of rate of patient/graft, infection but increase the incidence of acute rejection. Because CsA can increase incidence of neurotoxicity, it is suggestion to treat patients of nervous systerm disease with FK506.

AIM: The selective recognition of the sense peptides which are located in special regions of thyrotropin receptor (TSHR) by their corresponding antisense peptides has been investigated. Three pairs of sense and antisense peptides were named TR1 (aa37-45) and RT1 (aa45-37), TR2 (aa353-366) and RT2 (aa366-353), TR3 (aa648-655) and RT3 (aa655-648). METHODS: To prepare three affinity chromatography columns, antisense peptides were immobilized, called RT1-sepharose 4B, RT2-sepharose 4B and RT3-sepharose 4B, respectively and investigate the retardative behavior for each of native peptide TR1, TR2 or TR3 on above columns with stepwise elution. RESULTS: Each of the three immobilized antisense peptides recognized and retarded its corresponding sense peptide-TR1, TR2 or TR3 instead of those non-complementary peptides. Immobilized RT1 recognized free TSHR protein molecule as well. In additional, bovine thyrotropin was recognized by immobilized TR1. CONCLUSION: The results indicate that molecular recognition theory exsits in thyrotropin receptor system. It may be useful to isolate biological molecules and to locate epitopes of TSH on TSHR molecule. Otherwise, antisense peptide may be used for treatment of experimental autoimmunolized thyroid disease (AITD) in the rat. [

Objective:To observe the clinical effect of tuina plus foot bath with Chinese medicine for patients with diabetic foot (DF) in early stage.Methods:A total of 70 patients with early-stage DF were randomly allocated by the random number table into two groups,with 35 cases in each group.Patients in the control group received conventional medication,while patients in the observation group received tuina plus foot bath with Chinese medicine on the basis of conventional medication.The clinical efficacy was compared after 2 courses of treatment.Results:After treatment,intra-group comparisons of ankle-brachial index (ABI) showed statistical significance in both groups (both P＜0.05).The curative rate was 83.3％ in the observation group,with the total effective rate of 96.7％,versus 29.4％ and 76.5％ in the control group,respectively,and the between-group comparisons showed statistical significance (both P＜0.05),indicating a better effect in the observation group.Conclusion:Tuina plus foot bath with Chinese medicine has a good therapeutic effect for DF patients in early stage.

OBJECTIVE:To evaluate the curative efficacy of granulocyte macrophage colony stimulating factor (GM-CSF) as an adjunctive therapy for the treatment of acute myeloid leukemia (AML). METHODS: Randomized controlled trials (RCTs) of GM-CSF in the treatment of AML were retrieved from PubMed,EMBase,Cochrane Library,CBMdisc and CNKI database by computer as well as from the leukemia-related journals manually for a quality evaluation of the methodology and Meta analysis using RevMan5.0 software. RESULTS: A total of 10 RCTs were included,of which,3 RCTs were graded as A,5 as B and 2 as C. The results demonstrated that there were no significant differences of indexes among groups as complete remission (CR) rate,relapse rate,infection rate and length of hospital stay,etc. CONCLUSION: The available clinical research results showed that GM-CSF adjunctive therapy could neither increase CR rate,nor decrease the relapse rate,infection rate or length of hospital stay.

OBJECTIVETo observe the effects of "menstrual cycle-based acupuncture therapy" on ovarian function and pregnancy results of in vitro fertilization-embryo transfer (IVF-ET) in patients with decline in ovarian reserve (DOR).

METHODSA total of 63 patients of DOR who received treatment of IVF/intracytoplasmic sperm injection (ICSI) were randomly divided into an observation group (30 cases) and a control group (33 cases). The patients in the observation group were treated with "menstrual cycle-based acupuncture therapy". The syndrome differentiation and treatment were given based on different phases of menstruation. Shiqizhui (EX-B 8) and Mingmen (GV 4) were selected during menstrual phase, Shenshu (BL 23), Geshu (BL 17), Sanyinjiao (SP 6) and Taixi (KI 3) were selected after menstruation, Qihai (CV 6), Guanyuan (CV 4), Zigong (EX-CA 1), Zusanli (ST 36) were selected during ovulatory period, Qihai (CV 6), Guanyuan (CV 4), Yanglingquan (GB 34), Taichong (LR 3) were selected before menstruation. The acupuncture was given twice a week until second menstrual cycle of oocyte retrieval. The total times of acupuncture was (15 ± 2). After acupuncture, patients were treated with IVF-ET. The patients in the control group were treated with IVF-ET but no acupuncture. The indices of ovarian reserve function, including basic follicle-stimulating hormone (FSH), estradiol (E2), antral follicle count (AFC), number of retrieved oocytes, number of fertilization and number of high quality embryo, were compared and analyzed before and after acupuncture in the observation group. The differences of outcomes of IVF-ET, including the cycle cancellation rate, implantation rate, the clinical pregnancy rate, were compared between the two groups.

RESULTSCompared before acupuncture, the E2, AFC, number of retrieved oocytes, number of high quality embrgo and number of fertilization were all increased after acupuncture in the observation group (all P< 0. 05). Compared with the control group, levels of the E2, the number of retrieved oocytes, number of fertilization and number of high quality embryo were all increased in the observation group (all P < 0.05). Also, the implantation rate, the clinical pregnancy rate were improved (both P < 0.01) and cycle cancellation rate was reduced (P< 0.01).

CONCLUSIONThe "menstrual cycle-based acupuncture therapy" can effectively improve the ovarian reserve function in DOR patients, leading to an improved clinical pregnancy rate of IVF-ET.

Objective To study the relationship between plasma creatinine and lactic acid levels in type 2 diabetic patients with normal renal function, and the effect of mefformiu administration on plasma lactic acid. Methods Blood samples were collected from 723 type 2 diabetic inpatients(275 cases treated with mefformin as treatment group and 448 without mefformin as control group). Plasma lactic acid was measured with enzyme-electrode assay. The fasting plasma glucose, fasting insulin, creatinine (Cr) , alanine aminotransferase (ALT), and HbA1C levels were also determined. Results (1) The lactic acid level in treatment group was significantly higher than that in control group [(1.33±0.57 vs 1.17±0.47) mmol/L, P<0.01] and so was the incidence of hyperlactacidemia (9.45% vs 4.91%, P<0.01). No lactic acidosis was found in all patients. (2) The correlation analysis showed that Cr, blood urea nitrogen, ALT and body mass index (BMI) were positively correlated with lactic acid in control group, and the positive correlation between Cr and lactic acid still existed (r= 0.345, P<0.01) after adjustment for ALT and BMI. (3) After being divided by 20 μmol/L Cr in control group, lactic acid levels in subgroup increased with the Cr levels, especially when Cr was over 90 μmol/L. The Cr cutpoint for predicting lactatemia was 95.35 μmol/L. Conclusion It is safe to administrate metformin in type 2 diabetic patients with normal renal function, along with low risk of lactic acidemia. The incidence of lactic acidemia may increase when plasma Cr level reaches 95.35 μmol/L,

Objective To explore the effect of health education through different postoperative follow-up method, including telephone、Email and QQ, on patients with indwelling D-J stents. Methods 319patients with indwelling D-J stents were divided into the control group(88 cases), the telephone group(89 cases), the Email group (70 cases) and the QQ group (72 cases). M1 patients received rourine health education during hospitalization and before discharge, the latter three groups received follow-up by telephone、Email and QQ after discharge respectively. The rehabilitation effect was observed in the four groups. Results The complication rates of the telephone group, the Email group and the QQ group was significantly less and the mastering of knowledge about prevention and handling of complication was better than the control group during the follow-up. Conclusions Different types of follow-up can be selected by patients according to their actual status. Decreasing complication rate, favorable social benefit and approval of the patients family members will be seen due to involvement of the patients family in health education.
