Objective To investigate changes in the expression of apurinic/apyrimidinic endonuclease (APE) and the oxidative DNA damage marker 8 OHdG in distant hippocampus regions of the rat brain after focal cerebral ischemia of the middle cerebral artery.Methods SD rats were divided into the sham surgery group and the pMCAO group (induced by middle cerebral artery occlusion).Pathological changes in brain tissues were examined at 2 h,6 h,12 h,24 h,48 h and 72 h.The expression of APE and 8-OHdG was measured by immunohistochemical staining methods.TUNEL staining was performed to detect apoptosis.Results Reduction of APE expression in the CA1 region of the hippocampus on the ischemia side appeared at 2 h in the pMCAO group and continued as ischemia persisted (F=11.91,P＜0.05).The expression of 8OHdG and TUNEL immunoreactivity in the CA1 region of the hippocampus on the ischemia side were first observed at 6h in the pMCAO group and intensified during the remainder of induced ischemia (F=9.23 and 10.46 respectively,P＜0.05 for both).Compared with the sham group,8-OHdG expression and TUNEL immunoreactivity in the pMCAO group were at nearly the same levels from 24 h to 72h.Conclusions Oxidative DNA damage occurs in hippocampus regions of the rat brain after experimentally induced focal cerebral ischemia of the middle cerebral artery.APE expression declines in regions distant from focal cerebral ischemia.Development and accumulation of oxidative DNA damage can induce apoptosis in certain brain regions.

Objective To explore the association between syndrome types of primary hepatic carcinoma(PHC) and coagulation function.Methods From Jan.2015 to May.2016,a total of 176 cases of PHC patients were enrolled to analyze the correlation between syndrome types and coagulation function.Results The liver stagnation and spleen deficiency syndrome(34.66%) was the most common syndrome in all patients,followed by wet and heat resistance syndrome(22.73%) and qi stagnation and blood stasis syndrome(17.05%).Prothrombin time(PT),activated partial thromboplastin time(APTT),thrombin time(TT) and D-dimer(D-D) levels of patients were significantly increased,with significant differences between liver stagnation and spleen deficiency group and wet and heat resistance syndrome group,liver and kidney Yin deficiency syndrome group(P<0.05).While fibrinogen(FIB) decreased significantly,but without significant differences between each group(P>0.05).Conclusion Coagulation function in PHC patients with spleen and kidney Yang deficiency syndrome,wet and heat resistance syndrome and liver and kidney Yin deficiency syndrome could be poor,but that in patients with qi stagnation and blood stasis syndrome and liver stagnation and spleen deficiency could be relatively good.Increasing of PT,APTT,TT and D-D could be with certain significance to identify liver stagnation and spleen deficiency syndrome with other syndrome types.

AIM: To observe the effects of scleral buckling surgery for retinal detachment under microscope and under indirect ophthalmoscope.
METHODS: Forty - six patients ( 46 eyes ) with rhegmatogenous retinal detachment were retrospectively analyzed. Twenty-six patients received surgeries under microscope was retrospectively analyzed and compared to that of 20 patients who received surgeries under indirect ophthalmoscope by the same operator.
RESULTS: No statistical difference was found in patients' operation method choice, including condensation reaction reattachment situation and the retina reset operation at a time ( P> 0. 05 ). The best corrected visual acuity of microscopic group after 1mo of operation was better than before operation, and the improving rate of vision after operation was higher than that of the traditional group (P<0. 05).
CONCLUSION:The curative effect of external approach microsurgery has the similar efficacy with the conventional external approach surgery, and gets better visual acuity.

Objective To investigate the contribution of hypoxia-inducible factor inhibitor YC-1 to cisplatin chemo-sensitivity to human ovarian cancer cells A2780s in vitro. Methods Ovarian cancer cells were divided into four groups which were treated with saline, YC-1, cisplatin, and YC-1+cisplatin, separately, mRNA of HIF-1αand VEGF in the A2780s cells were detected by real-time fluorescence quantitative PCR by calculating 2-△△CT;the protein were detected by Western blot, to evaluate the change of hypoxia and angiogenesis capabilities under the ovarian cancer microenvironment. Results Compared with the control group, mRNA and protein of HIF-1αand VEGF expressed less in the group of YC-1, cisplatin and YC-1+cisplatin;while, those in the group of YC-1+cisplatin were lower than the monotherapy (P<0. 05), but no significant difference was detected between the YC-1 and cisplatin groups, and the expression of HIF-1αand VEGF mRNA were positively related(r=0. 830 5)in each group. Conclusion YC-1 exerts the antitumor effect and may contribute to sensitivity to cisplatin in the therapy of ovarian cancer.

Objective To investigate the correlation between serum insulin-like growth factor-1(IGF-1)level and the 131Ⅰahsorbante of thyroid nodule in patients with struma nadosa,to search for simpler and safer methods for differentiating thyroid nodule.Methods Detecting the 131Ⅰ absorbance of thyroid nodule by radioisotope scanning.then the patients were divided into warm and cold nodule groups,and the normal control group was also set up;the levels of IGF-1,FT3,FT4,sTSH were detected in serum of patients with struma nadosa by radio immunoassay,then the correlation between these data and the 131Ⅰabsorbance of thyroid nodule was analyzed.Results In the patients with warnl nodule,the level of serum IGF-1,FT3,FT4 and the 131Ⅰ absorbance of thyroid nodule[(315.86±22.74)μg/L,(9.95±5.62),(67.27±27.31)ng/L,0.64±0.17]were increased obviously when compared with the control group [(256.13±39.85)μg/L,(2.80±1.30),(13.51±5.50)ng/L,0.35±0.15],but the sTSH[(0.35±0.03)mU/L]went down significantly than the control group[(2.71±1.17)mU/L],the difference being statistically significant(P＜0.01).In the patients with cold nodule,the level of serum IGF-1,FT3,FT4,sTSH[(263.17±30.23)μg/L,(2.89±0.98),(14.23±2.84)ng/L,(2.81±0.42)mU/L] had no significant difference compared with the control group(P＞0.05).The level of serum IGF-1 was positively correlated with the 131Ⅰ absorbance of thyroid nodule(r＝0.835,P＜0.01),but negtively correlated with sTSH(r＝-0.326,P＜0.05)in the patients with warm nodule.Conclusion The level of sernm IGF-1 is closely correlated with the 131Ⅰ absorbance of thyroid nodule in patients with struma nadosa.

Objective To evaluate the effect of CYP3A5 genetic polymorphisms on tacrolimus (Tac) concentration/dosing and other clinical outcomes in a pilot cohort of 113 Chinese HTx recipients.Methods Association between CYP3A5 genetic variants and blood dose-adjusted trough concentrations (C0/D) of Tac at 1st month at the beginning of the immunosuppressive therapy was evaluated in cohorts of 113 patients,then at 1st,3rd,6th,and 12th months after transplantation in 41 patients who received Tac-based immunosuppressive therapy and never changed within one year after transplantation,respectively.In addition,we also evaluated the association between CYP3A5 genetic variants and other clinical outcomes,such as the classifications of endomyocardial biopsy and longterm prognosis.Results The CYP3A5 wild homozygote (* 1/* 1),mutant homozygote (* 3/* 3),and mutant heterozygote (* 1/* 3) occurred in 5,34 and 74 recipients respectively.The gene mutation rate of CYP3A5 in this cohort of Chinese HTx recipients was 80.5 ％ and the homozygous proportion was 65.5％.Compared with CYP3A5 expressors (* 1/* 1 or * 1/* 3),CYP3A5 nonexpressors (* 3/* 3) had a higher Tac C0/D at 1st month (47.34 ± 11.40 vs.116.11 ± 42.40 vs.293.70 ± 171.20,P =0.000),as well as other studied time points (3rd month:98.32 ± 39.43 vs.292.07 ± 141.08,P=0.003;6th month:90.00 ± 21.31 vs.341.68 ± 165.02,P =0.002;and 12th month:96.02 ± 29.33 vs.339.23 ± 162.30,P =0.018);and might have a lower classification of endomyocardial biopsy at 1st month (1.43 ± 0.73 vs.1.50 ± 0.58,P =0.867),3rd month (1.55 ±1.00 vs.2.00 ± 1.73,P =0.512),and 6th month (1.36 ± 0.84 vs.2.33 ± 1.53,P =0.132);as well as a higher mortality due to acute organ rejection (10％ vs.0,P =0.244) and all-cause mortality (20％ vs.9.7％,P =0.580).Conclusion In Chinese HTx recipients,the frequency of this * 3 allele is lower than that has been reported in the white population.The determinations of CYP3A5 genetypes in heart transplant recipients are helpful to guide the individualized Tac regimens.

Objective:To evaluate the clinical effect of Limb dysfunction after the comprehensive treatment of ischemic stroke by Traditional Chinese Medicine (TCM).Methods:A total of 160 patients with limb dysfunction after ischemic stroke. Who in line with the inclusion criteria, were randomly divided into 2 groups by random number table, 80 cases each. These patients were treated in Multicenter Union Hospital from June 2017 to Janunry 2019. The patients in the control group were given basic Western medicine treatment and rehabilitation training, while the patients in the observation group were given a comprehensive treatment combined with traditional Chinese medicine based on the control group (Chinese herbs, herbal fumigation and ear point press). Both groups were treated for 4 weeks and follow-up for 2 months. The Fugl-Meyerscale were used to evaluate the degree of limb dysfunction and balance dysfunction, the National Institutes of Health Stroke Scale were used for assessing the damage extent of nerve function, the Barthel index for evaluating the mobility of daily life. The clinical efficacy was evaluated according to the method of Brunnstrom assessment.Results:After treatment, the Limb strong spasm (1.57 ± 0.36 vs. 1.98 ± 0.53, t=5.724), Hemianesthesia (1.37 ± 0.31 vs. 1.80 ± 0.36, t=8.096), Inhibited bending and stretching (1.31 ± 0.25 vs. 1.84 ± 0.46, t=9.055) in the observation group were significantly lower than those in the control group ( P<0.01). The Fugl-Meyer activity and balance rating in the observation group were significantly higher than those in the control group ( t values were 2.739, 4.705, respectively, P<0.05 or P<0.01). The total effective rate of observation group was 93.3% (78/80), the control group was 73.3% (71/80), and there exist statistical significance ( χ2=4.783, P=0.028) in the two group’s comparative difference. Conclusion:The comprehensive TCM treatment can improve the hemiplegia syndrome of ischemic stroke patients and their limb activity and balance function, promote their neural functional recovery, enhance the activity of their daily life and clinical efficacy.
