AIM: To establish the technique of precision-cut fibrotic liver slice (PCLS) and grope the optimal cultural conditions for researching the liver xenobiotic metabolism in vitro and the drug interaction. METHODS: Complex factors (higher fat diet, alcohol and CCl 4) were used to make the animal model of liver fibrosis. Fibrotic liver slices were prepared and cultivation system was established. Lactate dehydrogenase (LDH) leakage, glutathione S-transferase (GST) activity and 3[4,5-Dimethythiazole-2-yl]-2,5- diphenyltetrazolium bromide (MTT) reduction were chosen as indexes to assess the viability of the slice in different thickness, medium pH and cultural time. RESULTS: Rats were in earlier hepatic fibrosis after administration for 3 weeks. When the thickness of slices was 300 ?m and medium pH was 7.0, the LDH leakage, GST activity and MTT reduction could maintain on a steady level in 6 h. CONCLUSION: A 300 ?m of thickness, 7.0 of medium pH and 6 h of cultural time are the optimal slicing and culturing conditions for fibrotic liver slice.

Objective To study the efficacy and adverse reactions of the treatment on different types of infantile hemangiomas (IH) with different doses of propranolol .Methods One hundred and fifty cases of IH without contraindications were randomly treated with different doses of propranolol (low dose group:1 mg?kg -1 ?d-1 ;high dose group:2 mg?kg -1 ?d-1 ) under ECG monitoring inferior half an hour to breastfeeding taking ,and stay in hospital for observation for 6 to 24 hours after the treatment . The patients returned to the hospital for review every month(ECG and blood RT ;lung function in necessary) .Results The curative effect is better on strawberry IH than that on flat IH ,also better on deeply IH than that on superficial IH .The adverse reactions oc‐curred relatively slight in the low dose group and there was no significantly statistical differences on the treatment effects between the both groups(P>0 .05) .Conclusion It is safe and effective to treat IH with propranolol .

Strain QJ16,one of some methanotrophic bacteria isolated from soil samples utilizing the separate device designed by our laboratory;was studied in detail and identified as one of the Genus methylomonas through 16S rDNA sequencing and comparison. The culturing and reaction conditions for methane utilization of this strain were investigated. The results indicated that the optimal conditions for the growth of strain QJ16 were methane gas as carbon source and the coexistence of NH4Cl and KNO3 as nitrogen source,the cultivation temperature of 30℃ and medium initial pH 6～7,and the optimal Cu2+ concentration of 15 ?mol/L.

Objective In order to evaluate the efficacy of esophageal varices ligation( EVL) , ultrasonic microprobe (UMP) was used to observe the esophageal varices and their collaterals before and after EVL. Methods Sixty patients merely with esophageal varices underwent ultrosonography via UMP before and 4,8,12 weeks after EVL and were divided into three groups:( Ⅰ )esophageal varices(EV) ( Ⅱ )esophageal and paraesophageal vein(PEV) varices( Ⅲ ) esophageal, para esophageal and perforating vein( PV) varices. Results In the following-up, the effective rate of type Ⅰ , Ⅱ , Ⅲ were 75% , 25% , 0% ; The recurrence rate 16% , 75% , and 100% respectively. PEV occurred in 12 out of 24 cases of group Ⅰ and broadened in all of the cases of group Ⅱ and Ⅲ; PV occurred in 11 out of 20 cases of group Ⅱ and all cases in groups M , and broadened in all cases of group Ⅲ. Conclusion Endoscopic ultrasonography can be served as guidance in selecting therapeutic measure in treating EV. EVL is merely suitable in treating EV; in EV patients with PEV and/or PV measures other than EVL should he selected.

Objective To investigate the effects of extractum trametes robiniphila murr combinated with hydroxyurea on proliferation and apoptosis of K562 cells and whether the 2 drugs have synergistic effects,and to detect the antiproliferation and apoptosis ratio of cells in diffe-rent groups were detected.Methods K562 cells were cultured in vitro,and logarithmic phase cells were used for study.MTT-inhibitory test and cell morphological analysis were employed to examine the effects of extractum trametes robiniphila murr alone or in combination with hydroxyurea on proliferation of K562 cells.The effects of extractum trametes robiniphila murr alone or in combinated with hydroxyurea on apoptosis of K562 cells were examined by flow cytometry.The expressions of bcr-abl,bax and bcl-xl mRNA levels were detected by way of reverse transcription polymerase chain reaction(RT-PCR).Results Extractum trametes robiniphila murr could inhibit proliferation and induce apoptosis of K562 cells,and extractum trametes robiniphila murr combinated with hydroxyurea had a synergistic effects on cell prolife-ration and apoptosis.The RT-PCR displayed that either extractum trametes robiniphila murr alone or in combinated with hydroxyurea could down-regulate the expression of bcl-xl mRNA and up-regulate the expression of bax mRNA and the effect of the 2 drugs had a synergistic effect on bcl-xl and bax mRNA expressions.Extractum trametes robiniphila murr alone could also down-regulate the expression of bcr-abl mRNA,but hydroxyurea alone did not show any effect on the expression of bcr-abl mRNA and the 2 drugs had no synergistic effect.Conclusions The effect of extractum trametes robiniphila murr combinated with hydroxyurea on the proliferation and apoptosis of K562 cells has a synergistic effect.The mechanism of antiproliferation and inducing apoptosis of extractum trametes robiniphila murr is probably related to down-regulating the expression of bcl-xl and bcr-abl mRNA and up-regulating the expression of bax mRNA.The synergistic effect of antiproliferation and inducing apoptosis of extractum trametes robiniphila murr combinated with hydroxyurea on K562 cells is probably related to down-regulating the expression of bcl-xl mRNA and up-regulating the expression of bax mRNA.

Objective To investigate the corrective effect of modified Brisson technique to treat concealed penis in children.Methods From July 2014 to July 2016,selected 12 patients (3-10 years old,mean 7.2 years old) with concealed penis were surgically treated with the modified Brisson technique in the Second Affiliated Hospital of Nanjing Medical University.Their clinical manifestations included the penis buried below the surface of prepubic skin which can be palpated and visualized through pushing the skin around the penis to the pubis and the short foreskin which was not attached to the penile corpus cavernosum.Patients with other conditions such as obesity and penial agenesis that caused buried penis were excluded from the study.The modified Brisson technique consisted of 4 steps.Ventral incision was used to gradually slit the narrow ring of the prepuce and to expose the glans followed by circumfe-rential inner foreskin incision made below the coronary sulcus of penis then the foreskin stripping released the corpus cavernosum.Finally the skin coverage was accomplished by posthioplasty.The operation time,blood loss,complications,postoperative treatments and followed-ups were retrospectively analyzed.Results For all the 12 patients,the operations were successful,lasting 40 to 60 minutes.The bleeding was about 5 to 10 mL and there was no operation-related complications like bleeding and infection of incision.Satisfactory cosmetic outcomes were obtained without retraction and the scars were similar to those of circumcision.All patients had penile lymphedema postoperatively which disappeared within 6 months after operation.Follow-up ranged from 6 months to 1 year,and there were no complications like skin necrosis and contracture or voiding difficulty.Conclusions The modified Brisson technique for concealed penis repair is technically easy and safe.In addition,it provides a good cosmetic appearance,functional outcomes and excellent postoperative satisfaction grades.
