The effect of various concentrations of copper and zinc on anoxia-reoxygenation in the neonatal rat heart cell cultures was studied by determining the activity of superoxide dismutasc (SOD), glutathione peroxidase (GSH-px), the content of malondialodchyde (MDA) and the release of lactate dehydrogenasc (LDH) The results showed that teh activity of SOD decreased and the activity of GSH-px, the content of MDA and the release of LDH increased following anoxia and reoxygenation. The actiwty or SOD appeared to be increased by either copper or zinc to varying degrees, but the effect of copper showed to be stronger than that of zinc. The release of LDH was reduced at the presence of lower amounts of copper or zinc, but the effect of zinc was better than that of copper. The increased release of LDH occured when higher amounts of copper or zinc were added to the medium. In addition, copper increased the activity of GSH-px while reducing the content of MDA significantly.

Objective To investigate the clinical therapeutic effectiveness of fingering expansion anus with the application of acupoint treatment to patients with severe craniocerebral injury. Methods Ninety-one patients with constipation in our hospital from May 2013 - May 2015 were randomized into the control group ( n = 45 ) and the observation group ( n = 46 ) . All patients were implemented with routine care of constipation . Based on those regular treatments , the patients in the observation group received the treatment of anus expansion with fingers accompanying plus acupoint treatment with rhubarb powder for three days. The short-term therapeutic effectiveness was evaluated after 3 days of treatment while the long-term therapeutic effectiveness was analyzed 2 weeks later. Results After performing this treatment for 3 days and 2 weeks, the overall clinical symptoms of constipation in the treatment group was significantly lower than those of in the control group (P<0.05). Both the long-term therapeutic effectiveness after treatment two weeks and the short-term therapeutic effectiveness of the observation group were significantly better than those of the control group (P<0.05). Conclusions Anus expansion anus with fingers together with acupoint application in treating constipation is convenient and accessible. Its high effectiveness and limited side-effects can be the best evldence for its unlimited potential of clinical popularization and application.

Objective To establish age specific reference ranges of serum total prostatic specific antigen (T PSA) and to investigate the relationship between T PSA,free PSA (F PSA) and ratio of F PSA/T PSA(F/T) with age in benign prostatic hyperplasia (BPH) patients. Methods 913 consecutive cases were studied retrospectively.In all of them with the age ranged from 30 to 89, serum T PSA and F PSA levels were assayed.All the patients were suspected to be BPH or PCa,103 being diagnosed as PCa on biopsy under B ultrasound and the other 810 being BPH. Results The incidence rate of PCa was 11.3% in this group.Serum T PSA and F PSA levels were positively correlated with the age ( r=0.22,P

Objective To compare the serum PSA (T PSA and F/T PSA ratio) between patients of benign prostatic hyperplasia (BPH) and prostate cancer (PCa). Methods We studied retrospectively 810 cases of BPH and 103 cases of PCa consecutively from November of 1996 to June of 1999 and compared the differences of T PSA level and F/T ratio between these two kinds of diseases. Results In BPH patients,serum T PSA 10 ng/ml were 71.7%, 22.1 % and 6.2% respectively while these were 10.7%,17.5% and 71.8% in PCa patients ( P 10 ng/ml(0.110 ng/ml.

Objective To investigate the epidemic characteristics of malignant neoplasm of kidney and other urological malignancies in China. Methods The population-based cancer registration data between 1988 and 2002 were collected from 30 cancer registries in China.The data from 11 registries with continuous record were analyzed using the software Joinpoint Regression Program 3.3.1.The incidences of kidney cancer among 3 different periods(1988-1992,1993-1997 and 1998-2002)were compared. Results The incidence of renal cancer and other urological malignancies was 4.26 ,5.40,6.63 per 100 000 population during 1988-1992,1993-1997 and 1998-2002,respectively.The up-trend of kidney cancer incidence was statistically significant;however it was still lower in China than other parts of the world from 1993 to 1997. Conclusion The incidence of kidney cancer in China showed an upward trend in the past 15 years and more attention is needed.

Objective To investigate the epidemic characteristics of prostate cancer in China. Methods The population-based cancer registration data between year 1988 and 2002 were collected from 30 cancer registries in China. The data from 11 registries with continuous record were analyzed using the software Joinpoint Regression Program 3.3.1, and the incidence of bladder cancer among 3 different periods (1988-1992, 1993-1997 and 1998-2002) were compared. Results The inci-dence of prostate cancer was 1.96, 3.09, 4. 36 per 100 000 during 1998-1992, 1993-1997 and 1998-2002, respectively. The up-trend of prostate cancer incidence was statistically significant, how-ever it is still lower in China compared with other parts of the world from 1993 to 1997. Conclusions The incidence of prostate cancer in China showed a significant upward trend year by year, and prostate cancer might be one of major cancer in China. We should pay attention to it.

Objective To explore the related factors of hepatitis B virus(HBV) drug resistance and their clinical significance . Methods The retrospective analysis was performed on the dinical data in 153 cases of CHB in our hospital during 2011-2013 .The 8 viral drug resistance loci of 4 known nucleosides analogues lamivudine ,adefovir ester ,entecavir and telbivudine were performed the direct sequencing by using the double DNA end termination method(Sanger method);the related clinical factors of drug‐resist‐ant virus genotypes were statistically analyzed and the correlation between prognosis and drug resistance was analyzed .Results A‐mong 153 patients with CHB ,47 cases(29 .8% ) appeared virus genotype drug‐resistant ,the common sites were 204M‐I(18 cases) , 204M‐V(8 cases) ,followed by 181A‐T(10 cases) ,181A‐V(5 cases) ,then 180L‐M (14 cases) .The proportion of viral drug resist‐ance in the patients with family history ,HBeAg positive ,using the nucleotide analogues in the past and the baseline ALT≥5 times was significantly increased ,the incidence rates were 38 .8% ,34 .8% ,34 .6% and 50 .0% respectively .The multivariable COX re‐gression found that HBV‐DNA genetic drug resistance increased the risk of progression to cirrhosis of the liver ,the OR value was 4 .704(95% CI:1 .199 -18 .454) .Conclusion the Sanger method for direct sequencing is reliable and accurate method of HBV‐DNA genotype drug resistance .The proportion of viral drug resistance in the patients with a family history of hepatitis B ,HBeAg positive ,using nucleotide analogues and baseline ALT≥5 times is significantly increased;HBV‐DNA genotype drug resistance also increases the risk of progression to cirrhosis of the liver .

ObjectiveTo study the effects and mechanisms of hypoxia-ischemia (HI) on long-term learning and memory abilities and astrocytes in hippocampal formation and the efficacy of nimotop in treating hypoxic-ischemic brain damage. MethodsThe rats were subjected to right common carotid artery ligation followed by exposure to 8% oxygen at 37℃ for 2 h and then 13 rat pups received an introperitoneal injection of nimotop per day immediately following cerebral hypoxia-ischemia for 5 days. When the rats were 80-day-old, they were given test of Y-maze to determine their learning and memory abilities, and then their brain tissues were studied by immunohistochemistry for glial fibrillary acidic protein (GFAP) that marked astrocytes. ResultsThe learning and memory abilities of the HI group were lower than those of the normal control and nimotop treated group (P<0.01), nimotop significantly increased Y-maze learning abilities (P<0.05) of rats received HI, but did not affect their memory abilities. The numerical density of GFAP-positive cells in CA1 radiatum stratum of hippocampal formation were markedly higher in the HI group than those in the other two groups (P<0.01), but the others strata showed no difference. ConclusionHypoxic-ischemic brain damage cause rats to disorders of learning and memory that may be correlated with increase astrocyte in hippocampal formation which became easy to be damaged of declining regulation abilities of neurons microenvironment. Nimotop may be effective to counteract hypoxic-ischemic brain damages.
