AIM: To investigate the role of angiotensin II (Ang II)and Ang II receptor (Ang II R) in the ischemic injury of kidney.METHODS: The expression of renal Ang II type 1 receptor (AT 1R) gene in renovascular hypertensive rats was detected by reverse transcriptase-polymerase chain reaction (RT-PCR), and levels of Ang II in the kidney and plasma were examined by radioimmunoassay.RESULTS: The study showed that the contents of Ang II in plasma and renal tissue in experimental group were increased signifiantly ( P

Objective To explore the effect and significance of systemic inflammatory response syndrome(SIRS )score in predicting prognosis in acute craniocerebral trauma. Methods The clinical data of 620 patients were collected at admission from January 2003 to December 2007, GCS and SIRS score were calculated in 24 hours.The relation of the mortality rates and GCS score were analyzed in different SIRS score patients by controlling age. Results With SIRS score increasing,mortality rates increased as well,and pa-tients with SIRS (score≥2) mortality rates had significantly higher,and also in the same age and GCS score group.Mortality rotes were significant in staifistics (P<0.05). Conclusion SIRS score is significant inde-pendent predicting prognosis in acute craniocerebral trauma and in clinic.

There are two populations of bacteria to affect the formation of urinary stones in humanity. The first one can promote the formation of urinary stone by increasing urinary pH, decreasing concentration of urinary inhibitors , and damaging the protective urothelial glycosaminoglycan layer. The second inhibit the formation of urinary stones. These bacteria ( mainly the intestinal oxalate degrading bacteria such as Oxalobacter formigenes, lactic acid bacteria, Enterococcus faecalis etc) can decrease urinary oxalate concentration by regulating exogenous oxalate. The problems faced and the developing direction were also indicated.

Objective To detect chromosome translocation t (11;18)(q21;q21) and expression of BCL10 protein in gastric mucosa associated lymphoid tissue (MALT) lymphoma. Methods We, combining clinical and pathological data, detected API2 MLT fusion by reverse transcriptase polymerase chain reaction (RT PCR)as well as the expressions of BCL10 protein and Ki 67 by immunohistochemistry in cases of gastric MALT lymphoma and follicular gastritis (FG) and analyzed the relationships among them. Results API2 MLT fusion was detected in three cases (2 low grade and 1 low to high grade) out of 14 cases of gastric MALT lymphoma, and no in 8 cases of FG. BCL10 protein was weakly expressed in cytoplasm of B cells of germinal center in lymph follicles of FG; but abundantly in cytoplasm of tumor cells in gastric MALT lymphoma; 42.5% of the latter showed weak expression in nucleus. The expression of Ki 67 was significantly higher in low to high and diffuse large B cell lymphoma cases than in low grade cases( P 0.05), the frequency of nuclear expression of BCL10 increased with the increased expression of Ki 67. Conclusions Both API2 MLT fusion and BCL10 nuclear expression are associated with transformation of gastric MALT lymphoma from LG to HG. RT PCR technique used to detect API2 MLT fusion may be an important tool in identification of t(11;18)(q21;q21).

0.05).However,the percentage of patients with cholecystolithiassis was 86.5% in IGC group,and 50.6% in GC group(P=0.000).Besides the percentage of IA stage in IGC group(29.7%) was relatively higher than that(9.0%)in GC group(P=0.03);the surgical resection rate of tumor in IGC group was 56.8% and 32.6% in GC group(P=0.01).Nevertheless,the percentage of advance stage in IGC group(43.2%) was relatively lower than that in GC group(74.2%)(P=0.001).The overall 1,3,and 5-year survival rate of IGC group was 70.0%,31.2% and 26.8% repectively,and the mean survival time was17 months(51?13);which were significantly higher than those in GC group,in which the 1,3,5-year survival rate was 27.0%,17.7% and 15.1% repectively and the mean survival time was(25?8),5 months(all P=0.006).Single factor analysis showed that the survival time in IGC patients was influenced by the TNM stage(P=0.000),pT-category(P=0.000),operation-category(P=0.008);however,postoperative pathological grade(P=0.080),age(P=0.188) and sex(P=0.234) had no influence on survival rate.According to multivariate analysis,pT-category(P=0.000)was an independent factor for the survival time of IGC.Conclusions Comparing with GC group,IGC has a higher percentage of cholecystolithiassis,IA tumor stage and surgical resection rate,and thus,it has relatively better progonosis.pT-category is the vital independent prognostic factor in IGC.If a patient in ICG has been misdiagnosed during the primary operation,the patient should be re-operated for radical excision as soon as possible,except when the tumor is in stage Tis or T1a.

Cervical cancer is one of the leading causes of death in women with malignancies worldwide.Brachytherapy plays an essential role in the radiation therapy for cervical cancer, and its combination with external beam radiation is indicated for previously untreated or recurrent cervical cancer at various stages without distant metastasis.Magnetic resonance imaging (MRI) has superior resolution of soft tissue, which allows for accurate delineation of target volume, protects organs at risk (OARs), and thus improves treatment outcomes.In recent years, many studies have demonstrated the feasibility and superiority of three-dimensional MRI-guided brachytherapy for cervical cancer.This article aims to elaborate on relevant MRI techniques, selection of applicators, delineation of target volume and OARs, evaluation of treatment plans, and the clinical effect of three-dimensional MRI-guided brachytherapy.

Hemodynamic monitoring is an essential part in the care of children with congenital heart disease during perioperative period to guide clinical management.Currently,there are several methods available for hemodynamic monitoring.The invasive methods include the Fick method,thermodilution method,using the Swan-Ganz catheter and the pulse contour method.The noninvasive methods include partial carbon dioxide resorption,impedance method.In this paper,the principle,advantages and disadvantages of these monitoring methods in children undergoing cardiopulmonary bypass surgery were reviewed.
