Objective To explore the role of tissue inhibitor of metalloproteinase-1(TIMP-1) during renal senescence by using human TIMP-1 transgenic mice.Methods Renal histological changes of wild type mice and transgenic mice at the age of 3,12,24 months were observed by periodic acid-schiff(PAS)staining of paraffin sections.The numbers of F4/80 positive cells were detected by immunofluoreseence.The protein expressions of TIMP-1,TIMP-2,matrix metalloproteinase(MMP)-9,MMP-2,intercellular adhesion molecule-1(ICAM-1),transforming growth factor?1(TGF-?1),collagenⅢand collagenⅣwere detected by Western blot.The activities of gelatinases and TIMP-1 were examined by gelatin zymography and reverse zymography respectively.Results Focal renal fibrosis was found in two genotypes with aging.At the age of 24 months,compared with wild type,in kidneys of transgenic type,the expressions and activities of gelatinases were dowregulated (MMP-2:2.08?0.20 vs.3.39?0.43;MMP-9:4.02?0.82 vs.6.72?1.40,all P＜0.05);the expressions of collagenⅢ,collagenⅣ,ICAM-1,and TGF-?1 were upragulated(0.72+0.11 vs.0.57?0.09;0.84?0.13 vs.0.6?0.11,0.72?0.12 vs.0.53?0.07; 0.69?0.12 vs.0.45?0.09,all P＜0.05),and the numbers of F4/80 positive cells were increased (18.8?4.4 vs.12.7?3.6,P＜0.05)with the upregulated expression and activity of TIMP-1(1.10?0.18 vs.0.62?0.09;50.75?7.25 vs.20.64?3.50,P＜0.05).Conclusions TIMP-1 could promote age-related renal fibrosis through enhancing inflammation reaction by ICAM-1 upregulation.

OBJECTIVETo observe the impacts on skeletal fluorosis pain, joint motor dysfunction and urine fluoride excretion in the treatment with fire needle therapy, electroacupuncture and calcium carbonate D3.

METHODSThe randomized controlled trial was adopted. Ninety-five patients were randomized into a fire needle group (31 cases), an electroacupuncture group (33 cases) and a calcium carbonate D3 group (31 cases). In the fire needle group and the electroacupuncture group, Ashi points, Dazhui (GV 14), Geshu (BL 17), Quchi (LI 11), Hegu (LI 4), Xuehai (SP 10) points were selected and stimulated with fire needle and electroacupuncture separately, three times a week. In the calcium carbonate D3 group, calcium carbonate D3 tablets was prescribed for oral administration, 600 mg each time, twice a day. The duration of treatment was 2 months in the electroacupuncture group and calcium carbonate D3 group and 1 month in the fire needle group. VAS score, the range of motion (ROM) and urine fluoride value were compared before and after treatment in the patients of the three groups.

RESULTSAfter treatment, VAS value and ROM were improved significantly in the patients of the three groups (all P < 0.05), the difference was not significant in comparison of the three groups (all P > 0.05). After treatment, the urine fluoride value was increased significantly in the fire needle group [(7.89 +/- 3.61) mg/L vs (9.81 +/- 4.17) mg/L, P < 0.01] and was increased in the electroacupuncture group [(7.53 +/- 3.46) mg/L vs (8.97 +/- 4.21) mg/L, P < 0.05]. The difference was not significant in comparison before and after treatment in the calcium carbonate D3 group (P > 0.05).

CONCLUSIONThe fire needle therapy, electroacupuncture and calcium carbonate D3 all have the clinical value in the prevention and treatment of skeletal fluorosis and the difference in the therapeutic effect has not been discovered among them yet at present. But it has been found that the fire needle therapy and electroacupuncture display the active significance in the promotion of urine fluoride excretion.

OBJECTIVETo observe the therapeutic effect of preconditioning acupuncture (PA) on the treatment of primary dysmenorrhea.

METHODSEighty patients suffered from primary dysmenorrhea were randomly assigned on the ratio of 1:1:2 into three groups, 20 in Group A, 20 in Group B, and 40 in Group C. Group A and B were treated with PA and immediate acupuncture (IA), respectively, while Group C received no acupuncture treatment and be taken as a blank control. The treatment was lasted for three menstrual cycles. The therapeutic effects were observed and compared.

RESULTSComparing the scores of the symptoms in the different groups, the therapeutic effect in different groups showed that the symptom scores in Group A at the second and third cycle of treatment, as well as at the first and third cycle of follow-up, were significantly lower than the scores in Group B, respectively (P<0.05 or P<0.01), and the duration of symptoms was shorter in Group A than in Group B at the third cycle of treatment and the first and third cycle of follow-up (P<0.05). Symptom scores in Groups A and B in the treatment and follow-up periods were all lowered as compared to those before treatment (P<0.01), and the scores were also lower than those in Group C measured at corresponding times (P<0.01).

CONCLUSIONThe therapeutic effect of PA, either the short-term or the long-term effect, was superior to that of IA in treating dysmenorrhea.

Objective To analyse the influencing factors of quality of life (QOL)among postoperative children with congenital anorectal malformation (ARM), so as to provide evidence for developing comprehensive interventions and improve QOL of children with ARM.Methods The QOL of 100 children aged at 2 and 5 years old were evaluated by using the Chinese version of PedsQLTM4.0 scale, and the total and 4 dimensions scores of QOL were calculated.Univariate and multiple stepwise regression model was applied to analyse the influencing factors of the QOL.Results The results of univariate analysis among ARM children aged at 2 years old showed that the clinical classification, bowel disorders and family residence have different influence on QOL scores of the 4 dimensions and total scale (P ＜ 0.05).The results of univariate analysis among ARM children aged at 5 years old showed that the clinical classification, bowel disorders and maternal education had different influence on QOL scores of the 4 dimensions and total scale (P ＜ 0.05).The results of multiple stepwise regression model among ARM children aged at 2 years old showed that the major influence factor of QOL scores in physical function was family residence and bowel disorders(P ＜ 0.05), the major influence factor of QOL scores in social functioning was bowel disorders(P ＜ 0.05), the major influence factor of the total scores was bowel disorders and family residence(P ＜0.05).The results of multiple stepwise regression model among ARM children aged at 5 years old showed that the major influence factor of QOL scores in physical function was maternal occupation and clinical classification(P ＜ 0.05), the major influence factor of QOL scores in emotional functioning was bowel disorders(P ＜ 0.05) ,the major influence factor of QOL scores in social functioning was clinical classification and bowel disorders (P ＜ 0.05), the major influence factor of QOL scores in school performance was maternal occupation(P ＜ 0.05), the major influence factor of total scores was bowel disorders and clinical classification(P ＜ 0.05).Conclusion Family residence and bowel disorders have effct on QOL of ARM children aged at 2 years old.Maternal occupation, clinical classification and bowel disorders have effct on QOL of ARM children aged at 5 years old.We should take positive interventions on these influencing factors to improve QOL of children with ARM.

AIM: To investigate the effects of in situ transplantation of mobilized autologous bone marrow stem cells on infarction size and cardiac function in patients with acute myocardial infarction. METHODS:25 patients with first acute myocardial infarction were randomly divided into stem cells in situ transplantation group and control group, 12 patients in stem cells in situ transplantation group were injected subcutaneously with 300 ?g granulocyte colony-stimulating factor(G-CSF) daily for four days in addition to standard therapy. 13 patients in control group were treated with standard therapy alone. The conventional 12 leads electrocardiogram were recorded on 1, 28 days after admission and the cardiac function was scored by the QRS scoring system proposed by Wagner. Furthermore, the infarction size was assessed by radionuclide myocardial perfusion imaging 7, 28 days after admission. RESULTS:4 weeks after admission, the QRS scores decreased, the infarction size reduced significantly in the stem cells in situ transplantation group (from 36.0%?8.3% to 18.0%?5.8%, P

Trypanosoma is a human parasite severely affecting poor tropical areas.However,current frontline drugs for Trypanosoma treatment have severe side-effects with decreased effectiveness.Based on the fact that aminoacyl-tRNA synthetase is a bonafide drug target for several microorganisms,including bacteria and fungi,it is plausible that it may also be effective target of Trypanosoma.The Trypanosoma brucei leucyl-tRNA synthetase(tbLeuRS)was cloned,expressed and purified to develop an in vitro enzymatic assay system.The assay conditions were further optimized for the effective screening of tbLeuRS inhibitors thus establishing an anti-Trypanosoma drug screening system targeting tbLeuRS.The results indicated that this system can be employed for the effective screening of anti-Trypanosoma drugs with satisfactory specificity.In addition,this system can also be used for compound optimization,as well as IC50 testing.Using this system a series of compounds are identified that are effective Trypanosoma inhibitors without toxicity to human cells.Therefore,targeting tbLeuRS may represent a new venue for the development of anti-Trypanosoma drugs.

Objective: To observe the clinical effects of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) in the treatment of shoulder and arm pain. Methods: A total of 90 patients with shoulder and arm pain were randomly divided into an observation group and a control group, 45 cases in each group. The treatment of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) was adopted in the observation group, routine acupuncture was used in the control group. The two groups were treated once every day, with 5 treatments as one course, and a 2-day rest between two courses. After 3 courses, pain was assessed by visual analog scale (VAS), and the clinical effects were compared between the two groups. Results: After the treatment, VAS scores were significantly changed in both groups (both P<0.01). The VAS score was lower in the observation group than that in the control group, with a statistical difference between the two groups (P<0.05). The total effective rate was 100% in the observation group, versus 91.1% in the control group, the difference was statistically significant (P<0.05). Conclusion: The therapeutic effect of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) is better than that of routine acupuncture in treating shoulder and arm pain.

Objective To investigate the variation of electrocardiogram (ECG) in the course of aneurysmal subarachnoid hemorrhage (SAH) for predicting the prognosis. Methods The in-hospital data of 108 cases with aneurysmal SAH who had underwent ECG re-examination were retrospectivelyanalyzed to find out the relationship between characters of ECG and prognosis. Results Of the 108 cases, aneurysm clamping by eraniotomy was performed in 41 and endovascular intervention in 67; a total of 89 cases (82.4%) presented abnormal ECG primitively, 62 patients had 2 kinds of ECG changes at least; 71 patients presented abnormal ST-T, 13 cases with abnormal cardiac rhythm, 14 cases with delayed Q-T intermediate stage, 37 cases with abnormal T wave, 9 cases with abnormal Q wave, and 7 cases with other changes; 99 cases recovered in ECG re-examination, 5 cases partly recovered and 4 cases aggravated. GOS score was 4-5 in 98 cases, 3 in 7 cases, and 1-2 in 3 cases. Conclusion Though the type of ECG variation has no significant correlation with SAIl prognosis, ECG monitoring during the course of SAH is of important value for predicting the prognosis.
