Objective To evaluate modified retroperitoneal laparoscopic resection of renal cyst. Method Thirty-six patients with renal cyst were treated by modified retroperitoneal laparoscopic resection of renal cyst,summarized the clinic data and follow-up the effect. Results All 36 cases were operated suc-cessfuUy without changing to opening operation,average operation time (50 ± 35)min,no complications oc-curred and no recurrence was found. Conclusions The modified retroperitoneal laparoscopic resection of renal cyst with two 5 mm-trocars and one 10 mm-trocar has less trauma than classic laparoscopic operation. It is one of mini-trauma operation method which is worth to be popularized in clinic.

Objective To study the relationship between receptor interacting protein (RIP)1 and hepatocyte necropto?sis in isoniazid (INH) induced mouse model. Methods Kunming male mice were randomly divided into three groups. Con?trol group (C) received 0.3 mL of normal saline one time per day. INH group (INH) was injected intraperitoneally INH 100 mg/kg body weight, one time per day. Nec-1+INH group was injected intraperitoneally Nec-1 in 0.1%DMSO and 1 mg/kg body weight one time/12 hours, and INH was injected intraperitoneally at the same dose with that of INH group. All animals were treated for 7 days. Pathological changes of liver tissues were studied by HE staining. RIP1 expression was detected by immunohistochemical, Western blot and real-time PCR analysis. Levels of malondialdehyde (MDA), reactive oxygen species (ROS), glutathione (GSH) and superoxide dismutase (SOD) in liver homogenate were determined by colorimetric method. Re?sults Hepatocytes were arranged orderly in C group. The degeneration and necrosis of hepatocytes were found in Nec-1+INH group, and severe degeneration and necrosis of hepatocytes were found in INH group. Compared with C group, the ex?pression levels of RIP1, ROS and MDA were increased significantly, and the expression levels of GSH and SOD were de?creased significantly in INH group (P<0.05). INH-induced acute liver necroptosis was significantly alleviated after treat?ment with Nec-1. Compared with INH group, the expression levels of RIP1, MDA and ROS were significantly decreased, and the expression levels of GSH and SOD were significantly increased in Nec-1+INH group (P<0.05). Conclusion These re?sults suggest that RIP1 is involved in INH-induced hepatocyte necroptosis in mice. The inhibition of RIP1 expression might be a treatment strategy for prohibition of INH-induced acute liver necroptosis.

OBJECTIVE:To optimize the formulation of Dimemorfan phosphate tablets. METHODS:Using 60 min dissolution rate of dimemorfan phosphate as index,L9(34) orthogonal test was used to optimize the amount of starch,microcrystalline cellu-lose,croscarmellose sodium and concentration of HPMC E5 solution. The friability,hardness,60 min dissolution rate and main component were detected. The similarity of dissolution curves of Dimemorfan phosphate tablets was compared with that of imported tablets in 0.1 mol/L hydrochloric acid,pH 6.8 phosphate buffer,water and pH 4.0 acetate buffer. RESULTS:The optimized formu-lation of Dimemorfan phosphate tablet(1 000 tablets)was composed of dimemorfan phosphate 10 g,starch 60 g,microcrystalline cellulose 40 g,10% HPMC E5 solution and croscarmellose sodium 25 g. The friability,hardness,60 min dissolution rate and main component of 3 batches of Dimemorfan phosphate tablets prepared by optimized prescription were 0.42%-0.58%,9.8-10.5 kg,94.89%-96.21% and 99.21%-99.52%,respectively. In 4 dissolution mediums,similar factors f2 of dissolution curves between prepared tablets and imported tablets were above 50. CONCLUSIONS:Dimemorfan phosphate tablets were prepared successfully. The optimized formulation is rational. The dissolution behavior of prepared tablets is similar to that of imported tablets in vitro.

Objective To explore the effect of different cold ischemia (CI)times on the patterns of intra-graft T cell activation gene-3 (TCA-3) expression early after isogeneic half liver transplantation (PLT)in mice. Methods The models of C57BL/6 full-size(FS) and PLT were established.The CI time was 1,4 and 8 h.Specimen were collected at 4 and 24 h post-reperfusion.Ribonuclease protection assays (RPA)was used to evaluate serial mRNA expression of the TCA-3 chemokine in all mice.Histopathology was used to examine cold ischemia injury in the liver grafts. Results A total of 45 control and 30 PLTs were performed.The survival rate at 7 day after control and PLT was 100％.Quantitative analysis demonstrated the levels of TCA-3 mRNA expression were low at 4 h after reperfusion in control group with 1,4,8 h CI.The levels of TCA-3 significandy increased at 4 h after reperfusion in PLT group with CI of 1,4,8 h and the difference between the two groups was statistically significant ( F =7.41,P ＜ 0.05 ). TCA-3 mRNA expression significantly decreased at 24 h after reperfusion in two groups. But the difference was not statistically significant ( P ＞ 0.05 ). Histopathology showed severer cold ischemia injury in PLT grafts compared with control grafts. Conclusions The expression of TCA-3 significandy increased early after PLT and played an important role in cold ischemia injury.TCA-3 could be used as the early therapeutic target for reducing ischemia injury in PLT grafts.

Objective To study the effects of different drying processes on the effective constituents in Wen Codonopsis pilosula (WPP) Decoction Pieces; To develop the optimized producing and preparing integration process based on fresh WPP.MethodsFresh WPP in harvest period was prepared respectively as follows:① Fresh WPP was dried to different percentage (30%–100%) of original moisture contents of crude drugs at 80℃ in oven, then sliced and dried at 50℃ to obtain eight decoction pieces of WPP (XⅠYP1–8).② The fresh WPP was baked to 50% of water content of crude drug under different temperatures (50–120℃), respectively, then sliced and dried at 50℃ to obtain eight decoction pieces of WPP (XⅡYP1–8).③ Dried WPP was moistened, sliced and naturally dried, then were renamed as traditional decoction pieces. The contents of lobetyolin and atractylenolideⅢ was determined by HPLC. The phenol-sulfuric acid and colorimetric method were applied respectively to detect contents of polysaccharide and total flavonoids. The contents of aqueous and alcoholic extracts were determined simultaneously. Results The contents of alcoholic extracts (55.36%), aqueous extracts (54.91%) and atractylenolideⅢ (10.95 μg/g) in XⅠYP3 pieces were higher than other decoction pieces.Conclusion The optimized process was that fresh WPP was baked to water content of 50% at 80℃, then sliced and dried. Compared with conventional preparing methods,the integration process was time-saving and effort-saving. Meanwhile, the prepared pieces have higher content of active ingredients.

The detection limit of chloroform, ethyl acetate and DMF was 0. 63,0. 60 and 8. 92μg·ml-1 , respectively. The residues of the organ-ic solvents in three batches of the samples all met with the requirements of ICH. Conclusion: The method is sensitive, accurate and reliable, and can be used in the quality control of dimemorfan phosphate.

Objectives To investigate the expression and clinical significance of HOXA10 gene in the eutopic and ectopic endometrium of endometriosis.Mehtods Between Jan.2009 to Aug.2010,30 patients with endometriosis undergoing laparoscopic surgery in Maternal and Children's Hospital of Foshan.Eutopic and ectopic endometrium were obtained.In the mean time,30 patients with benign ovary cyst or tubal infertihty undergoing laparoscopic surgery were selected as controls.Their uterine endometrium were obtained real-time fluorescent quantitation,western blot and immunohistochemistry technique were used to detect mRNA and protein expression of HOXA10 gene in the eutopic endometrium group,ectopic endometrium group and control group.Results The mRNA and protein expression of HOXA10 gene were 0.61 ±0.07 and 0.47 ±0.05 in the eutopic endometrium of endometriosis,0.64 ±0.06 and 0.50 ±0.05 in ectopic endometrium of endometriosis,which were significantly lower than 1.22 ± 0.14 and 1.42 ± 0.14 in control group ( P ＜ 0.01 ).However,the mRNA and protein expression of HOXA 10 between eutopic and ectopic endometrium of endometriosis did not reach statistical difference ( P ＞ 0.05 ).The expression of HOXA10 in eutopic and ectopic endometrium of endometriosis were decreased by immunohistochemistry staining.Conclusion The lower expression of HOXA10 gene in the eutopic and ectopic endometrium of endometriosis might be associated with pathogenesis and infertility of endometriosis.
