ABSTRACT
Suppressor APC domain containing 2 (SAPCD2) gene may affect tumor proliferation, invasion, migration and apoptosis, and participate in tumor-related signal pathway transduction, suggesting that SAPCD2 may be a biomarker of tumor and a potential target for treatment. Therefore, SAPCD2 has been widely concerned by researchers. This article reviews the role and related mechanisms of SAPCD2 in tumors.
ABSTRACT
Objective To study the protective effect of total trans retinoic acid (ATRA) on renal injury induced by ischemia-reperfusion in rats.Methods 24 Sprague Dawley (SD) rats were divided into 4 groups of (1) Normal control group,(2) Sham operation group,(3) Model group:the model of renal ischemia-reperfusion was established.(4) Retinoic acid treatment Group:ATRA were given by gavage for 7 consecutive days.The rats were killed 24 hours after the model,and the serum and renal tissue were collected.Serum creatinine,tumor necrosis factor-α (TNF-αx) and interferon-γ (IFN-γ) levels,kidney biopsy,renal tubular score,renal damage and renal tissue apoptosis were detected.Results Compared with the model group,the serum creatinine level decreased and the creatinine clearance rate increased in ATRA treated group (P ＜ 0.05);the damage of renal tubular epithelial cells was alleviated in the pathological slices;and the apoptosis rate of renal tubular epithelial cells was decreased (P ＜ 0.05).Serum levels of TNF-α and IFN-γ decreased (P ＜ 0.05).Conclusions ATRA can protect the renal ischemia-reperfusion injury through inhibiting inflammatory reaction and apoptosis.
ABSTRACT
The clinical data of 143 patients with type Ⅱ a hepatolithiasis with normal function of the sphincter of Oddi were analyzed.The patients were divided into two groups at random.The data of the 2 groups of patients were compared on the operating time,hospitalization,rates of complication,residual stone rates and recurrence rates.The A group patients underwent laparoscopic video choledochoscopic hepaticocholangiolithotomy,T-tube drainage and choledochoscopic lithotomy.The B group patients underwent laparoscopic video hepatectomy and choledochoscopic lithotomy.For most of the patients in the A group,the treatment had the advantages of less trauma,less complications and quicker recovery.There was no significant differences in residual stone rates and recurrence rates between the two groups.As it was difficult to remove stones in the caudate lobes of Ⅱ a type patients in A group due to the sharp angle between the hepatic duct and bile ducts of the caudate lobe,individualized programs should be adopted according to the location of stones on individual patients.
ABSTRACT
Objective To explore the protection and mechanism of hydrogen sulfide (H2S) preconditioning against injury induced by cisplatin in human marrow mesenchymal stem cells (HMMSCs).Methods HMMSCs were treated by cisplatin at 0,5,10,20,40,60,80 mg/L concentrations for 24 h respectively and were exposed to cisplatin at 20 mg/L concentrations for 0,6,12,24,36,48 h respectively.HMMSCs were pretreated with NaHS at 0,0.4,0.6,0.8,1.0 mmol/L respectively for 30 min before exposed to cisplatin at 20 mg/L concentrations for 24 h.HMMSCs were treated by U0126 or combined with human epidermal growth factor (HEGF) together for 30 min before they were preconditioned with NaHS for 30 min.The cell survival rate,cell apoptosis rate,the expression of p-ERK1/2 and t-ERK1/2 were recorded.Results The cell survival rate decreased to 71.72％±2.72％,59.41％±5.44％,50.37％±4.55％,38.97％±2.92％,30.11％±4.64％ and 21.71％±5.35％ respectively after cells were treated with cisplatin at 5,10,20,40,60,80 mg/L concentrations respectively,and the differences were statistically significant compared with 0 mg/L group.The cell viability fell to 70.30％±6.20％,61.63％±2.70％,51.29％±3.13％,38.72％±3.66％ and 27.57％±2.32％ after HMMSCs were treated with cisplatin at 20 mg/L for 6,12,24,36,48 h respectively,and the differences were statistically significant compared with 0 h group.The cell viability increased to 65.99％±2.67％,72.93％±5.44％,75.10％±4.71％ and 76.56％± 5.25％ when HMMSCs got pretreatment of NaHS,and the differences had statistical significance compared with cisplatin group.The cell apoptotic rate decreased from 35.29％±2.77％ to 18.62％±0.97％ when HMMSCs were pretreated with NaHS at 0.6 mmo/L.Treatment of HMMSCs with cisplatin at 20 mg/L for 24 h reduced p-ERK1/2 expression.The pretreatment of NaHS could inhibit the inhibitory action to the expression of p-ERK1/2 induced by cisplatin.Pretreatment with U0126 or HEGF inhibited or promoted the protection and the upregulated expression ofp-ERK1/2 caused by NaHS pretreatment.Conclusion The preconditioning of H2S can protect cell damage caused by cisplatin via activating the ERK1/2 pathway of HMMSCs.
ABSTRACT
Objective To study effect of application of clinical nursing pathway in patients undergoing transurethral resection of prostate. Methods Clinical nursing pathway was established accorded with patients undergoing transurethral resection of prostate.Patients admitted before the application of clinical nursing pathway were set as the control group,while those admitted after the application of clinical nursing pathway were set as the experimental greup.The hospitalization time,medical cost, mastering degree of disease-related knowledge and satisfaction degree were compared between the two groups. Resets The hoapitalization time was shorter, the medical cost was lower, the mastering degree of disease-related knowledge and satisfaction degree were improved in the experimental group compared with those of the control group, P < 0.05. Conclusions Application of clinical nursing pathway in patients undergoing transurethral resection of prostate can improve nursing quality and reduce the economic burden of patients.
