ABSTRACT
Objective: To assess the clinical efficacy of Xuebijing injection in the prevention of postoperative systemic inflammatory response syndrome (SIRS) in the patients with ureteral stones and urinary tract infection during the perioperative period of ureteroscopy.Methods: Totally 64 cases with ureteral stones complicated with urinary tract infection treated with ureteroscopy were selected as the subjects and divided into two groups according to the digital method.The 32 cases in the control group were given the conventional antibiotics during the perioperative period for preventing the incidence of SIRS, and the observation group was given 500ml Xuebijing added to 100ml normal saline for intravenous drip additionally.The incidence of SIRS and the laboratory indicators after the operation were observed and compared between the groups.Results: The incidence of postoperative SIRS of the observation group was 9.38% , which was lower than that of the control group (34.38% , P <0.05);the incidence of sepsis of the observation group was 0%, while there was no statisticcally difference bettween the two groups(P＞0.05).The C-reactive protein (CRP), procalcitonin (PCT), leucocyte count and endotoxin in the observation group on the 2nd, 4th and 6th day after the operation were better than those in the control group, and the difference was statistically significant (P＜0.05).Conclusion: Xuebijing injection combined with antibiotics has significant clinical effect on the incidence of SIRS after ureteroscopy in the patients with ureteral stones and urinary tract infection, which can effectively improve the clinical indicators and reduce the incidence of sepsis, and is worthy of clinical promoted application.
ABSTRACT
Objective The occurrence and progression of renal cell carcinoma ( RCC) is complicated process associated with DNA abnormal methylation , histone modification , and Wnt signaling pathway .This study aimed to investigate the expression of histone methylase SET8 in RCC, its relationship with the Wnt signaling pathway , its action mechanism in RCC , and its clinical significance . Methods We selected 50 cases of RCC treated by radical nephrectomy , detected the expression of SET 8 in the RCC and adjacent noncancerous kidney tissues by immunohistochemical EliVision two-step staining with β-catenin.We compared the expression levels of SET8 and β-catenin in the two types of tissue and analyzed their relationship with the patients′clinical information and the pathologic stage and grade of tumor as well as the correlation between the SET 8 andβ-catenin expressions . Results SET8 was mainly express in the cytoplasm of the RCC and noncancerous kidney tissues , partially in the cell membrane and nucleus , while theβ-catenin protein chiefly in the cell membrane of renal tubular epithelial cells in the normal kidney tissue .The expression levels of SET 8 and β-catenin in the RCC tissue were closely related to the TNM stage and tumor grade (P0.05), but that of β-catenin was remarkably higher in the former (68%[34/50]) than in the latter (4%[2/50]) (P<0.01).There was a positive correlation between the positive expression of SET 8 and the abnormal expression of β-catenin (r=0.219, P<0.05). Conclusion SET8-activated H4K20me-1 controls the activation and abnormal activities of the Wnt signaling pathway , affects the gene transcription and cell activity , and participates in the occurrence , progression, and distant metastasis of RCC .
ABSTRACT
Objective To evaluate the efficacy and safety of ureteroscopic endo-incision and drainage in the treatment of renal cysts.Methods Thirty cases(19 females and 11 males)of renal cysts(1 1 parapelvie cysts,15 simple cysts.and 4 multiple cysts)were treated with ureteroscopic endo-incision and drainage.The renal cysts were located in renal pelvis,and opened and decompressed by electrotme with ureteroscope.Double J stent was placed afterwards.Urinary and blood biochemistry were tested post-operatively.Results All the operations were successfully completed with no severe complication.The cyst managing time ranged from 15 tO 45 min.Urinary biochemistry(urinary protein and glucose)turned normal 1 2 days after the surgery.Patients were followed up for 3 to 9 months.Renal cysts disappeared in 24 cases,diminished in 4 cases,and recurred in 2 cases.Conclusion Application of ureteroscopic technique in the treatment of renal cyst is safe,effective and minimally invasive.
ABSTRACT
Objective To evaluate the protective effect of taurine on renal injury induced by high energy shock wave in rabbits.Methods Twenty rabbits were divided into the experimental (n=10)and the control group (n=10) at random.Both the groups were exposed to 1500 shock waves at 12.75 KV.In the experimental group, taurine (150 mg/kg) was given intravenously during the shock, while normal saline was given in the controls. Malondialdehyde(MDA) and superoxide dismutase(SOD) in serum were measured and the histological changes, the expression of heat shock protein 70(HSP70) in kidney were determined 3 days after the shocks.Results The level of MDA was(2.2±0.4) ,(2.1±0.4)mmol/L, and the level of SOD was (56.4±9.9) ,(55.8±10.1)μU/L respectively in the experimental and the control group before the shock.There was no significant difference between the two groups(P＞0. 05). After the shock, the level of MDA and SOD was (2.7±0.7)mmol/L, (55.3±5.7)μU/L respectively in the experimental group. There was no significant difference(P＞0.05) compared with the level of before the shock's. While in the control group, the level of MDA and SOD was (5. 7±0. 7) mmol/L, (33. 3±3. 5)μU/L respectively.There was significant difference (P＜0.05) compared with the level of before the shock's. The renal tubule scores of the experimental group and the control group after shocks were 7.2±0.8 and 31.8±1.9, respectively. And the HSP70 scores were 25.2±4.1 and 6.4±0.9, respectively. There was significant difference between the two groups (P＜0.05).Conclusions Taurine can effectively protect kidney from injury induced by high energy shock wave in rabbit.The mechanism may be related with its antioxidant capacity and inducing the synthesis of HSP70 in kidney.
