AIM:To observe the expression of Smad7 and Smad ubiquition regulatory factor-Smurf2 in rat glomerular mesangial cells (GMC) stimulated by the high concentration of glucose,and to investigate the effect of the ubiquition on Smad signaling by adding MG132 as a proteasome differential inhibitor. METHODS:Cultured rat GMC were divided into normal group (the concentration of glucose:5.6 mmol/L),high glucose group (20 mmol/L,30 mmol/L,respectively),therapy group (30 mmol/L glucose with MG132). The expressions of Smurf2 and Smad7 in each group were measured by indirect immunofluorescence and laser scanning confocal microscope. RESULTS:(1) The expression of Smurf2 in GMC in normal group was weak (25.93?3.35) whereas the expression of Smad7 was strong (64.09?7.43). (2) The expression of Smurf2 in high glucose group was stronger than that in normal group (P

Objective To observe the oral Simotang plus traditional Chinese medicine enema in treatment of postoperative adhesion intestinal obstruction in patients with colon cancer.Methods The clinical data of 45 colon cancer patients with postoperative adhesive intestinal obstruction was analyzed retrospectively.The patients were randomly divided into control group (22 cases) and treatment group (23 cases).The control group was given conventional treatment,the treatment group was treated with oral Simotang plus traditional Chinese medicine enema on the basis of conventional treatment.The clinical efficacy,traditional Chinese medicine syndrome integral,serum endothelin (ET),tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6) and other indicators were compared between the two groups.Results After treatment,the total effective rates in control group and treatment group were 86.4 ％ (19/22) and 91.3 ％ (21/23),the difference was statistically significant (x2 =5.201,P =0.016).The operation rates in control group and treatment group were 13.6 ％ (3/22) and 8.7 ％ (2/23),the difference was statistically significant (x2 =3.622,P =0.027).The treatment group had shorter gastrointestinal recovery time and hospitalization time,the difference was statistically significant (both P ＜ 0.05).Before treatment,the traditional Chinese medicine syndrome integral in two groups had no significant difference (t =0.826,P ＞ 0.05),after treatment,the integral in treatment group was lower than that in control group (t =0.553,P ＜ 0.05).In treatment group,the differences of ET,TNF-α,IL-6 between 3,5,7 d and 1 d were statistically significant (all P ＜ 0.01),and compared with the control group at the same time,there were obvious advantages(all P ＜ 0.01).Conclusion The efficacy of oral Simotang and traditional Chinese medicine enema in treatment of adhesive intestinal obstruction after resection of colorectal cancer is clear,it is worthy of clinical application.

Objective To sum up experience with surgical excision of isolated local recurrence for renal cell carcinoma. Methods From March 2004 to November 2007, 7 patients (five cases un-derwent radical nephrectomy and two nephron-sparing surgery) with isolated local recurrence of renal cell carcinoma were treated at our department. All patients underwent extensive surgery for local re-currence. Results The mean patient age was 42 years (range 19 to 6). The mean time to local re-currence was 23.3 months (range 12 to 54). The Mean size of the recurrent tumor was 5.2 cm(range 2.5 to 10.5). Peritoneal exploration was performed in 7 patients and 5 had complete en bloc excision of the renal cell carcinoma mass. 2 patients gross disease was excised. The mean blood loss was 1050 (150-3000) ml. Surgical complications occurred in 2 patients, iliohypogastric nerve injure in one and ileus performation in another one. All patients recovered finally. Six patients were followed and one lost follow-up. Mean follow-up time was 13(8-27) months. One patient died of metastatic disease at 22 months after excision of the renal cell carcinoma mass. Conelusion En bloc excision of isolated locally recurrent renal cell carcinoma is possible, and complete surgical resection could lead to pro-longed disease-free survival.

Protozoans,the natural host of the facultative intracellular pathogen Legionella species,play an important role in survival,proliferation,virulence and stress resistance of Legionella species. By repeating transformation and selection,a spontaneous mutant of plasmid over expressing green fluorescent protein was obtained. This mutant replicates and is maintained stably in Legionella cells. The colonies of L. pneumophila harbouring the mutated plasmid were intense green in colour even under the daylight. After feeding BF1 strain of Tetrahymena thermophila with transformed L. pneumophila,the intracellular dynamic of changing of bacterial shape,bacterial proliferation and lysis of the host cell due to the bacterial proliferation were observed clearly under fluorescent microscopy. Thus,the present paper provides a simple and intuitionistic strategy for investigating the ecological and cellular relationship between L. pneumophila and its host.

Objective To provide a clinical anatomic basis for the bi-pedicled gastrocnemius myocuta- neous flap which is to be used to repair defects of the Achilles tendon and posterior skin of the ankle.Methods In anatomic study,out of 30 cadaver specimens,bi-pedicled V-Y gastrocnemius myoeutaneous flaps were harvested to measure the downward sliding lengths of the flap when the knee was at flexion of different degrees.In clinic,12 patients with the Achilles tendon and posterior ankle skin defects were repaired with the bi-pedicled gastrocnemius myocutaneous flaps.The areas of composite defects ranged from 10 cm?6 cm to 6 cm?4 cm.They were followed up for four months to 12 years.Results The maximal sliding length of the flap reached (9.2?0.9)cm when the knee was at flexion of 90?.All the clinical flaps survived and ambulation of the patients recovered.The dorsiflexion and plantarflexion of the ankles reached 11.0??1.4?and 35.0??4.6?respectively.Conclusion This flap is suitable for one-stage repair of composite Achilles tendon defects.

Cytoplast and microprotoplast are main subprotoplasts that can play an important role in plant genetic improvement.The present review highlights the advancements in isolation and fusion of plant subprotoplast,and some suggestions and prospects are proposed for the future studies.

AIM To study the therapeutic effects of Deketoprofen trometamol (D KPT) on adjuvant arthritis (AA) and its side effects on gastroduodena. METHEDS The change of primary and secondary inflammatory and the injury effect of gastroduodena treated with D KPT were observed. The effect of D KPT on prostaglandin E 2 (PGE 2) produced by peritoneal macrophage (PM) on AA rats in vitro was also observed. RESULTS D KPT (2 5, 5, 10 mg?kg -1 ) significantly inhibited primary inflammatory, secondary inflammatory and multiple arthritis of AA rats. D KPT(10 -8 ,10 -7 ,10 -6 ,10 -5 ,10 -4 mol?L -1 )inhibited the elevated PGE 2 released from PM of AA rats in vitro . D KPT (10 mg?kg -1 ) significantly injured gastroduodena on AA rats, but the degree of injuries was less than that of ketoprofen (KP) (10 mg?kg -1 ). CONCLUSION D KPT has therapeutic effects on AA rats, and its injury effect on gastroduodena is less than that of KP.
