BACKGROUND: Ginkgetin has been widely acknowledged as having multiple pharmaceutical values in domestic and abroad. In many western countries, ginaton is imported in large amount. Domestic production of ginkgetin is great, however, seldom applied and there is no ginaton agent for injection.OBJECTIVE: To observe the effects of the increased contents of total flavonoid glycoside and quercetin glycoside of ginkgetin injection on memory function of mice, superoxide dismutase (SOD) activity in myocardial tissues and hemorrheological indexes of rabbits with ischemia-reperfusion injury.DESIGN: Randomized control animal experiment.SETTING: Hebei Medical College of Employees.MATERIALS: Ninety Kunming mice (3-4 months old), weight (25±1) g and thirty-two Japanese rabbits (3-4 months old) were selected. Self-made high-purity ginkgetin injection [5 mL containing 17.5 mg ginaton, of which there were 8.7 mg ginkgo flavonoid glycoside (49.8%) and 4.61% lactone];Ginkgetin injection made in German (Jinnaduo): Manufactured by Schwabe Germany [5 mL containing 17.5 mg ginaton, of which there were 4.2 mg ginkgo flavonoid glycoside (24%)].METHODS: The experiment was conducted in the Central Department of Experimental Animal, Hebei Medical College of Employees from September to November 2002. ①Ninety mice were randomly divided into 6 groups:1, 2 mL/kg self-made ginkgetin injection group, 1, 2 mL/kg German ginkgetin injection group, model group and control group with 15 mice in each group. Mice in the model group and control group were intraperitoneally injected with normal saline, mice in each group were intraperitoneally injected respectively with testing medicine for 10 continuous days,One hour after the 10th day of administration, mice were intraperitoneally injected with 2 mL/kg scopolamine hydrobromide and dysmnesy models were duplicated. Ten minutes after that, mice were put in the step-down instrument for 36V-voltage-stimulus after accommodation. Measurements were re-performed respectively at 5 minutes and 24 hours after training.Latency and times of electric shock within 5 minutes were recorded.②Thirty-two Japanese rabbits were selected and randomly divided into normal control group, German ginkgetin injection group, 1 mL/kg, 0.5 mL/kg self-made ginkgetin injection group with 8 rabbits in each group. Medicineswere continuously injected into aural veins. Three days after administration, blood was collected to detect the hemorheological indexes. ③Thirtytwo rabbits were randomized into 4 groups: 1 mL/kg, 2 mL/kg self-made ginkgetin injection group, 2 mL/kg German ginkgetin injection group and normal saline group with 8 ones in each group. Rabbit models with ischemia-reperfusion injury in myocardial tissues were established, rabbits were ligated for 30 minutes and then unclamped to get ischemic reperfusion injury in myocardial tissues, testing drugs were injected via carotid artery at the moment of reperfusion according to different groups. Before reperfusion and 30, 60 minutes after reperfusion, blood was drawn from the arteria femoralis, activity of SOD in plasma was measured. Animals were executed to obtain myocardial tissues so as to measure SOD activity.MAIN OUTCOME MEASURES: ①Latency and times of shock within 5 minutes in the experiment were recorded. ②Hemorheological indexes and determination of SOD activity in myocardial tissues.RESULTS: All experimental animals were involved in the analysis of results and no one died. ①Test for memory: Latency and times of errors in step down test in the injection group were better than those in the control group, and differences were significant (P < 0.01 or 0.05). Times of errors within 5 minutes in 1 mL/kg self-made ginkgetin irjection group was less than that in the German ginkgetin injection group and the differences were obvious.②Hemorheological indexes: Whole-blood viscosity low shear value,rigid index of red cells and gathering index of red cells etc. in injection groups decreased. ③SOD activity: Compared with control group, that was significantly increased in 1, 2 mL/kg self-made ginkgetin injection group and were in a dose-dependent manner. Those were obviously increased in the 1 mL/kg German ginkgetin injection group. Increase in SOD activity of ischemic myocardial tissues in the 1 mL/kg self-made ginkgetin injection group was more significant than that in the 2 mL/kg German ginkgetin injection group.CONCLUSION: Both self-made and German ginkgetin injections can enhance the ability of memory; While at the basis of same dose, self-made high-purity ginkgetin injection is superior to German ginkgetin injection.

Objective:
To investigate the effect of the frenulum identification positioning method with a disposable suture device in circumcision for the prevention of postoperative penile frenulum malposition.
METHODS:
Totally 212 patients with phimosis or redundant prepuce underwent circumcision from March 2015 to September 2016, including 109 cases of conventional circumcision (the control group) and 103 cases treated by frenulum identification positioning with a disposable suture device (the observation group). We observed the postoperative position of the penile frenulum and median raphe and compared the deviation angles of the frenulum between the two groups of patients.
RESULTS:
The median of penile frenulum deviation angle (interquartile range) was 0 (3.56) in the observation group, significantly smaller than 12.41 (19.59) in the control (P <0.001, P = 0.000). And the rate of frenulum deviation was remarkably lower in the former (8.74% [9/103]) than in the latter group (66.06% [72/109]) (P <0.01).
CONCLUSIONS
Circumcision using the frenulum identification positioning method with a disposable suture device can effectively avoid postoperative penile frenulum malposition. With the advantages of safety and easy operation, it deserves clinical application and popularization.

OBJECTIVETo explore the possible relationship between erectile dysfunction (ED) and benign prostate hyperplasia (BPH) in men, and to assess the positive effect of Sildenafil on the lower urinary tract symptoms (LUTS) from BPH while treating ED.
METHODSThirty-two patients with ED and BPH were offered oral Sildenafil and reviewed before and six months after the administration of Sildenafil by the International Index of Erectile Function-5 (IIEF-5) and the International Prostate Symptom Score (IPSS) questionnaires. Scores were tested by chi-square.
RESULTSIIEF-5 scores were increased by 42.36% and IPSS scores declined by 20.14%, with statistical significance (P < 0.01).
CONCLUSIONTreatment of ED with Sildenafil appears to improve urinary symptom scores. A lower IPSS at baseline seems to predict a better response to Sildenafil therapy for ED.

Summary: To investigate the difference in expression of hTERT gene between HbsAg-positive human hepatocellular carcinoma (HCC) and HbsAg-negative HCC and to explore the relationship between HBV infection and hTERT gene expression in HCC. The expression of hTERT protein in 30 cases of HbsAg positive HCC and 17 cases of HbsAg negative HCC was detected by immunohistochemistry (SP method), and the expression of hTERT mRNA was analyzed by reverse transcription polymerase chain reaction (RT-PCR). t-test, Chi-squared test and cochran- armitage trend test were used to see whether there was an interrelation between HBsAg and hTERT gene in HCC. The expression of hTERT protein was mostly located in plasm and occasionally in the nucleus of liver cancer cells. The positive rate of hTERT protein and hTERT mRNA in HbsAg positive HCC- 93.33 % (28/30) and 83.33 % (25/30) respectively which were much higher than those in HbsAg negative HCC- 52.94 % (9/17), 47.06 % (8/17) (P<0.01) respectively. HbsAg is related to hTERT gene expression in human hepatocellular carcinoma. The hTERT gene activated by the efficacious ingredient of HBV may play an important role in hepatocellular transformation and carcinogenesis.
