The principal role of neutrophils in tissue repair has long been thought to be confined to killing bacteria and clearing necrotic tissue. However, recent studies have shown that neutrophils are also one of the sources of pro inflammatory cytokines and growth factors, such as IL 1, TNF ?, bFGF, VEGF,TGF ? 1 that probably serve as the earliest signals to activate local fibroblasts, epidermal cells and vascular endothelial cells and initiate tissue repair. It was also reported that neutrophils improved the proliferation removal of injured epithelial cells in airway and corneal epithelial cells. It is very important for the successful tissue repair that the function of neutrophils is normal.
2.Treatment of endoscopic sphincterotomy by endoscope to the patients with common duct stones after their gallbladders resected
Chinese Journal of Primary Medicine and Pharmacy 2009;16(5):844-845
Objective To evaluate the safety and therapeutic value of endoscopic sphincterotomy by endoscope to the patients with common duct stones after their gallbladders resected. Methods 158 patients with common duct stones after their gallbladders resected were given the treatments of endoscopic sphincterotomy and nasobiliary drainage in recent 4 years. Results 153 of 158 patients got succeed. The symptoms obviously improved such as jaundice and fever and epigastric distention and so on. As for the postoperative complications, the hyperamylasemia occurred in 85 patients of all patients,and active hemorrhage in 2 patients,and acute pancreatitis in 16 patients,and cholangitis in 5 patients,but no one occurred biliary fistula,no one died,too. Conclusion EST is the best way for us to treat the patients with common duct stones after their gallhladders resected by endoscope,and its curative effect is sure and its safety coefficient is higher.
3.Peripheral benzodiazepine receptors and cerebral ischemia
International Journal of Cerebrovascular Diseases 2009;17(4):305-308
1he increased peripheral benzodiazepine receptors are more significant than normal ones after cerebral ischemia. Its main reactions are the multiple pathological changes,including microglial activation, participating in neuroinflammation response, and regulation of mitochondrial function. Using radionuclide-laheled specific ligands of the peripheral benzodiaz-epine receptor (such as PK11195) for in vivo imaging contribute to the location and quantitative detection for brain injury and the study of the pathophysiological changes after cerebral ischemi-a. In addition, this receptor is promising to become a new target of neuroprotective treatment.This article reviews the recent progress in research on peripheral benzodiazepine receptors and cerebral ischemia.
4.INFLUENCE OF STARVATION ON THE DISTRIBUTION OF PHOSPHATASES, GLYCOGEN AND RIBONUCLEIC ACID IN THE MOUSE LIVER
Acta Anatomica Sinica 1954;0(02):-
Adult albino mice were starved for 66 to 120 hours and the liver was examined forphosphatases, glycogen and ribonucleic acid. Alkaline phosphatase was found to increasemoderately while acid phosphatase showed no significant change. Both glycogen andribonucleic acid disappeared completely. The periphery of the hepatic lobule often stainedmore deeply than the centre due mainly to the conspicuous staining of the cell borderand of the Kupffer cells. The duration of starvation had no infiuence on the amountof both alkaline and acid phosphatases. In the refeeding experiment, mice starved for 48 to 72 hours were refed and werekilled 11 to 72 hours after subjecting to normal diet. The liver cells contained even greateramount of glycogen than in control animals. The restoration of ribonucleic acid was onlypartial. Both alkaline and acid phosphatases showed variable activities in the refeedingliver. The liver cells usually swelled and became rarefied, the sinusoids were very in-conspicuous. The swelling and rarefation of liver cells were caused by the accumulationof glycogen during refeeding. Three days refeeding did not bring this histological pictureto that of the control liver.
5.Favorable outcome of ischemic stroke in patients pretreated with statins
Chinese Journal of Practical Internal Medicine 2006;0(21):-
Objective To evaluate the independent effect of premorbid statins on incident ischemic stroke severity and outcome at discharge.Methods We included consecutive patients with ischemic stroke and recorded demographic data,vascular risk factors,Oxfordshire Classification,the method of treatment National Institutes of Health Stroke Scale(NIHSS)score,previous statins treatment,and outcome discharge.We analyzed the data using univariate methods and a logistic regression with the dependent variable of good outcome(Barthel Index,BI 95 to 100).Results A total of 185 individuals met study criteria:57 patients were on statins agents prior to admission and 128 were on no statins.Pretreatment with statins was associated with lower presenting median NIHSS(6.0 vs 13.0,P
6.Experimental Study on Effect of Acupuncture Associating with TAX on General State and Tumour-curbed Rats of Lewis Lung Cancer Mice
Chinese Journal of Information on Traditional Chinese Medicine 2006;0(01):-
Objective Adopting acupuncture associating with TAX to treat mice with Lewis lung cancer,to investigate the anti-cancer effect and its mechanism,and affirm their cooperating effect. Methods Lewis lung cancer model in mice was established and treated with acupuncture,medication and the combination of acupuncture and medication separately. The growth state of the mice,change and growth curve of tumour,change of tumour-weight and tumour-curbed rate were observed. Results Acupuncture,TAX and the combination of acupuncture and TAX all can curb the tumour,and the combination was the best. Conclusion The combination of acupuncture and TAX has a marked anti-cancer effect and can improve growth state of the mice. The effect of combining method is better than single therapy.
9.Ageing-induced changes of peripheral benzodiazepine receptors in rat spinal cord synaptosoms
Chinese Journal of Geriatrics 2013;(5):561-563
Objective To investigate the changes of peripheral benzodiazepine receptors (PBRs)in rat spinal cord synaptosomes during ageing and to explore the correlation between PBRs in spinal cord synaptosomes and PBRs on platelet membranes.Methods A total of 24 Sprague-Dawley rats were divided into 3-month group and 24-month group (n=6 males and 6 females for each).All animals were sacrificed by decapitation and the spinal cords were immediately removed.Synaptosomal fractions from spinal cords were isolated by gradient centrifugation.The platelet membranes were prepared from venous blood by the method of hypotonic haemolysis.The specific binding of the radioactive PBRs antagonist [3H]PK11195 to membranes was determined.Results No significant differences in [3H] PK11195 binding activity in spinal cords and platelet membranes were observed between male and female rats in the same group (all P>0.05).[3H] PK11195 binding activity in spinal cords and platelet membranes were higher in 3-month group than in 24 month group [(213.94±10.65) fmol/mg pro.vs.(50.65± 2.74) fmol/mg pro.,(104.97± 2.24) fmol/mg pro.vs.(56.20±5.36) fmol/mg pro.,respectively,t=51.418,29.041,both P< 0.001].There was a positive correlation between [3H]PK11195 binding activity in platelet membranes and in spinal cord synaptosomes (r=0.985,P<0.001).Conclusions The level of PBRs is gradually decreased in rat spinal cord synaptosomes with ageing.[3H] PK11195 binding activity of platelet membranes can reflect the changes of PBRs in spinal cords.
10.Influencing factors of pharmacotherapy effect of ectopic pregnancy and nursing
Chinese Journal of Practical Nursing 2012;28(4):40-41
Objective To explore the influencing factors of pharmacotherapy effect of ectopic pregnancy and nursing measures. Methods 569 patients with ectopic pregnancy using pharmacotherapy were retrospectively analyzed in our department. Results Among 569 patients,423 patients gained successful treatment,while 146 patients failed the treatment.Blood β-HCG level,diameter of ectopic mass showed by B ultrasound were influencing factors of pharmacotherapy effect.The higher β-HCG level,the longer diameter of ectopic mass showed by B ultrasound,the lower success rate of pharmacotherapy.The patients with β-HCG<1000 mIu/ml,diameter of ectopic mass showed by B ultrasound less than 1 cm at admission acquired higher success rate of pharmacotherapy. Conclusions Patients with ectopic pregnancy who select conservative medication should be given pertinent psychological nursing,rigorous monitoring of disease condition and adverse reaction of drugs and timely and effective nursing measures,so that patients can get better nursing effect.
