1.Prevention and management of hypertension in the patients with renal diseases
Chinese Journal of Practical Internal Medicine 2003;0(01):-
Effective management for hypertension in renal diseases should be carried out according to the principles of 2007 ESH-ESC Practice Guidelines for the Management of Arterial Hypertension.The important role of kidney in the classification of hypertension,the corresponding therapy,the set of the target blood pressure,the choice of antihypertensive agents and combination therapy should be focused.Comprehensive approaches should be used for the treatment of hypertension in renal diseases to protect the target organs(including the kidney).Appropriate prevention and management strategies for hypertension in renal diseases should be disseminated and optimized.

Traditional Chinese medicine (TCM)has certain advantages in the treatment of chronic liver diseases,especially chronic inflam-matory injury and liver fibrosis.However,the studies on medicinal components and action mechanism of TCM prescriptions are confronted with a great challenge.The computational pharmacology methods used in recent years,mainly including virtual screening technique,omics technologies,and network pharmacology approaches,as well as their application in TCM research,are presented;given the previous re-search work,the progress in research on active ingredients and action mechanism of TCM prescriptions using computational pharmacology methods is reviewed.It is thought that computational pharmacology techniques combined with conventional molecular biological and pharma-cological methods are an important research strategy for the material basis and action mechanism of TCMprescriptions for treating chronic liv-er diseases.

Based on avian leukosis virus ( ALV) p19 gene terminal nucleotide sequence, a 82 bp double-stranded DNA fragment was chemically synthesized and cloned into the expression vector pGEMEX-1. The sequencing result indicated th at the cloned fragment was a correct version of the one designed both in nucleot ide sequence and in its open reading frame. The recombinant was used to transfor m E.coli BL21 (DE3). The cloned fragment was expressed as a fused protein wi th T7 gene 10 leader peptide and was shown to be 34 kD in size on SDS-PAGE gel when induced with 1 mmol/L IPTG. The expression product was able to bind immunol ogically to rabbit anti-ALV serum in Western-blot assay and is being tested to differentiate exogenous from endogenous ALV.

Objective To study the dynamic changes of transendothelial electrical resistance (TEER) on our in vitro model of brain blood barrier (BBB) made from primary culture of BALB/c mouse brain microvascular endothelial cells (BMVEC), and to explore the relation between TEER and BBB permeability, and search for the best culture condition. Methods BMVEC were isolated from BALB/c mouse and cultured on a transwell insert with special micro-pore. The cells were identified with immunohistochemical methods and electron microscope. TEER over BMVEC was measured after BBB model establishment for determining the 3H-Glucose permeability of BBB in vitro. Results BMVEC cultured in the transwell insert exhibited typical "flagstone" appearance and in a tight monolayer structure under electron microscope. Immunohistochemical detection of ZO-1 protein, a marker antigen of tight junction, showed smooth, continuous and tight junctions between confluent BMVEC. TEER over BMVEC monolayer increased to (346?10) ?/cm2 when the permeability for 3H-Glucose was decreased to the minimum. Conclusion BBB model in vitro made from primary culture of BMVEC in transwell has the basic characteristics of BBB in morphology, electrical resistance and permeability.

Objective To understand the status and features of nursing care adverse events and to offer scientific basis for improving patient safety management of nursing at high altitude area. Methods Data such as categories, causes, time distribution and other factors of nursing care adverse events were collected from January 2013 to August 2014 in the People′s Hospital of Tibet Autonomous Region were analyzed. Results Over the study period, 50 adverse events were recorded and the most common types were tube emersion(26%,13/50), pressure sores(14%,7/50) and scald(12%,6/50) respectively. The proportions of different severity of adverse events were hidden events (48%,24/50), events without bad consequence(36%,18/50), adverse events(14%,7/50) and warning events(2%,1/50) respectively. The ineffective communication, inadequate assessment, and not abiding by the rules accounted for 70%(35/50) of the causes of adverse events. 7:00-10:59 and 19:00-22:59 period was the high incidence of adverse events, respectively accounted for 32%(16/50) and 26%(13/50). Conclusions The management of nursing adverse events at high altitude area need to consider the geographical characteristics,besides, to guarantee the implementation of the system,reduce the bed / nurse ratio, improve the comprehensive quality of nurses and other measures can be taken to reduce the occurrence of adverse events.

Objective To investigate the value of the diagnosis of contrast-enhanced ultrasound(CEUS) in renal tumors. Methods Nineteen patients with hyperechoic renal tumors detected by CEUS underwent resection for suspected renal malignant and benign tumors. The characterization of hyperechoic renal tumors on CEUS was evaluated. Results Histopathologic results of resected lesions showed benign tumors in 11 patients with angiomyolipoma and malignancy in 8 patients with clear cell carcinoma. Six patients with angiomyolipoma showed rapid wash in contrast enhancement and slow wash out on all tumor and focal tumor (6/11). One patient with angiomyolipoma was observed in rapid wash in and wash out (1/11). Four patients with angiomyolipoma showed rapid wash in and negative contrast enhancement after rapid wash out(negative contrast enhancement compared to renal cortex,4/11). Five patients with clear cell carcinoma showed rapid wash in and wash out (5/8). Two patients with clear cell carcinoma showed rapid wash in and delayed wash out (2/8). One patient with showed no enhancement on CEUS (1/8). The pseudocapsule could be seen at 5 patients with clear cell carcinoma. Wash in enhancement and wash out on clear cell carcinoma were significant in comparison to these of angiomyolipoma (P<0.05). Wash in enhancement,delayed wash out and negative contrast enhancement were no significant between clear cell carcinoma and angiomyolipoma (P>0.05). Conclusions CEUS is useful for discriminating between benign and malignant renal tumor.
