1.Expression and modulation of connective tissue growth factor in renal interstitial fibrosis
Chinese Journal of Pathophysiology 1999;0(09):-
CTGF, a member of the CCN family of immediate early genes, is a recently discovered profibrotic growth factor, which is involved in many pathophysiologic procedures. CTGF acts as a downstream effector of TGF-? acting on interstitial cells to enhance the progression of fibrotic renal diseases. It has been shown that CTGF gene expression can be induced or blocked by some kinds of cytokine and drugs. It is an interesting candidate target for future intervention strategies of renal interstitial fibrosis. [

Objective To explore the distribution pattern of G protein-coupled receptor family C, group 6, subtype A (GPRC6A) mRNA in adult mice. Methods The distribution of GPRC6A mRNA in paraffin embedded adult mouse tissues was determined by highly sensitive nonradioactive cRNA probe in situ hybridization (ISH). We compared ISH with and without addition of tyramide signal amplification (TSA). GPRC6A wild-type and littermate GPRC6A null mice tissue sections were investigated by ISH. Results TSA greatly increased the sensitivity of ISH to detect GPRC6A mRNA in wild type mouse tissues. There was no detection of GPRC6A mRNA in GPRC6A gene specific knockout tissue in paraffin embedded tissue section. The mRNA of GPRC6A was detectable in the digestive gland or accessory digestive gland including salivary gland and pancreas, as well as in the tissues including kidney, testis, brain, muscle, and fat. Conclusion The mRNA distribution pattern of GPRC6A gene is compatible with the phenotype of GPRC6A knockout mice.

Objective Study the early and midterm results of a technique-total aortic arch replacement without using extracorporeal circulation or aortic bypass for the treatment of aortic aneurismal disease involving the transverse aortic arch and proximal descending aorta. Methods Between April and November 2004, 7 consecutive patients with true (n = 3) or false (n =4) aortic aneurysm underwent this procedure. The mean follow-up was 6. 6 years. The median age at operation was 57years ( range 23 to 75 years). Normothermia general anesthesia and median sternotomy combined with left anterior thoracotomy were administered. A partially occluding clamp was placed on ascending aorta and a longitude aortic incision was made. Anastomosis of a branched graft to ascending aorta in an end-to-side fashion was commenced. The descending aorta distal to the aneurysm was occluded and transected, and anastomosed to the distal end of the branched graft in an end-to-end fashion. Finally,the arch vessels were divided and anastomosed to the branches of the graft and the aneurysm excised. Results The average cross-clamp time of descending aorta, left common carotid artery, and innominate artery was (13.6 ±5.6)min, (5.7 ±0.8)min, and (7.8±2.5) min respectively. The mean intubation time was (12.3 ±4.1) hours. There were no adverse outcomes or neurologic complications in this series. All patients survived and recovered completely. The mean follow-up time was (79.7 ±2.1) months. All patients lead a normal life. There was no late death. CT follow-up study 6 years after surgery reveals no abnormal image. Conclusion Total aortic arch replacement without cardiopulmonary and aortic bypass is a feasible and effective method for the aortic aneurismal disease involving the transverse aortic arch and proximal descending aorta in selected patients.
