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 nervous mechanism of intestinal function disorder after intestine congestion through observing the changes of acetylcholinesterase (AchE) neuron and nitric oxide synthase neuron (NOS) expression in nervous system of rat intestinal tract. Methods Sprague Dawley rats were divided into experimental groups (intestine congestion 20min and 60min group) and the control group. Then the spreading specimens of intestinal myen-teric plexus of ileums were collected and stained by AchE and nicotinamide-adenine dinucleotide phosphate-D (NADPH-d) histochemistry, to observe and compare the density of distribution and staining of AchE and NOS positive neurons. Result Compared to the control group, the number and positive expression of AchE positive neuron in intestinal myen-teric plexus of ileums in the experimental group rats decreased (P

This paper introduces chief physician LIU Huilin's empirical characteristics in treating cluster headache based on holism and pattern-identification-based treatment,with spirit-regulating filiform needling,filiform fire needle pricking,and collateral-pricking for bloodletting sequential therapy,which inherits the academic thoughts of"acupuncture-moxibustion for treating spirit"from Professor ZHOU De'an and"three-unblocking acupuncture therapy"from HE Puren,thus providing a reference for treating cluster headache with acupuncture-moxibustion therapy.

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 To investigate the relationship between the antiproliferation effects of aloe-emodin on growth of gastric cancer cells and cell cycle arrest.Methods Human gastric cancer SGC-7901 cells were treated with 2.5,5,10,20,and 40 ?mol/L aloe-emodin for 1—5 d.The cell growth was determined by MTT assay.Cell proliferation and cycle distributions were analyzed by flow cytometry.Western blotting assay was used to detect the changes of cell cycle regulators,cyclins,and cyclin-dependent kinases(CDK).Results Aloe-emodin inhibited the growth of gastric cancer cells in a dose-dependent manner.Treatment of aloe-emodin resulted in cell cycle arresting at G2/M phase.Its molecular mechanisms involved the decrease of the expression of cyclin A and CDK2,the increase of the expression of cyclin B1 and CDK1.Conclusion One of the antitumor mechanism of aloe-emodin on the growth of gastric cancer SGC-7901 cells is to arrest the cell cycle,which indicates that aloe-emodin has a potential value for the treatment of gastric cancer in clinic.

Objective To summarize the methods and results of surgical treatment of coarctation of the aorta associated with aortic dissection.Methods Analyzed the clinical data of 10 patients with aortic coarctation associated type B aortic dissection who underwent one-stage surgical repair between 2011 and 2013 in Anzhen Hospital.There were 7 males and 3 females with the age ranged from 23 to 56 years,average at 41.2 years.All patients were diagnosed by UCG and CTA.There are three key points to determine the operation method,diameter of the aortic arch and descending aorta,and the extent of dissection.Descending thoracic aortic replacement with short stented elephant trunk was performed in 3 patients,thoracic and abdominal aortic replacement in 1 patient,ascending-abdominal aorta bypass with arch or descending aortic ligature in 3 patients.Results One hospital death occurred(10％).There was no severe surgical complication.No death or reoperation occurred during follow up period.Conclusion Aortic coarctation associated type B aortic dissection is a rare and complex disease.Surgical treatment is an effective and safe method for the disease.

Objective To investigate the effects of pyrroloquinoline quinone(PQQ) on the hippocampal neurons of aged rats induced by D-galactose(D-gal).Methods D-gal was used to induce the model of aging rat,PQQ was administered into rat lateral intracerebroventricle.After 50 days the metamorphosis of hippocampal neurons was observed by H-E and Nissl's staining.The apoptosis rate of hippocampus was tested by flow cytometry.The contents of free radical and C-FOS protern were measured.Results Compared with the control group,the size of the neurosoma was slightly changed,the optical density of Nissl's was decreased,the content of free radical and the apoptosis rate increased markedly in D-gal group.After PQQ injection with D-gal,the size of neurosoma and the optical density of Nissl's were markedly increased,the content of free radical and the apoptosis rate of hippocampus did not change.PQQ improved the expression of C-FOS protern.Conclusion PQQ can slow down the aging progress of hippocamal neurons induced by D-gal.

Aim To investigate the function of fenofi-brate on PAN ( puromycin aminonucleoside )-induced podocyte injury. Methods SD female rats of 18-week-old were randomly assigned into 3 groups ( n =6 ) . Mice in PAN group and fenofibrate treated group received a single intravenous injection of PAN ( 65 mg ·kg-1 ) , while those in control group received equal volume of saline. Mice in fenofibrate treated group re-ceived 40 mg · kg-1 · d-1 of fenofibrate ( intragastric administration ) on day 1 after PAN injection , while those in PAN group and control group received equal volume of vehicle. 24 hours urine samples from all group were collected on day 0(1 day before PAN injec-tion), day 6, day 10. The 24 hours urine protein was detected by Bradford assay. All the rats were sacrificed 10 days after the induction of podocyte injury, and glo-merulus sample were collected. The expression of podocyte injury marker and transcription level in apop-tosis, podocyte cytoskeleton protein, slit diaphragm protein were evaluated by Western blot and real-time PCR. Results Compared with the control group, 10 days after injection of PAN, 24 hours urine protein was obviously increased, and the expression and transcrip-tion level of podocyte injury marker desmin, apoptosis, podocyte cytoskeleton protein, slit diaphragm protein were upregulated greatly, however, those were signifi-cantly lower in fenofibrate treated group as compared with those in PAN group. Conclusions PPAR-α ago-nist fenofibrate can ameliorate PAN-induced glomerulus podocyte injury, and the mechanism involved may be associated with inhibition of the mitochondria apopto-sis, TGF-β/Smad pathway and p38 pathway.

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.
