Chinese Journal of Medical Education Research 2012;11(3):236-238
Taking the modern occupation education concept as the guide,oriented by adapting to the demand of occupation post,we established a new open education mechanism of medical occupation education to promote the reform of personnel training mode,curriculum and teaching content to explore the effective way of the sustainable development of local medical occupation education.
2.Transient receptor potential channels 6 in tumor
Journal of International Oncology 2011;38(9):656-659
Transient receptor potential (TRP) is a kind of novel Ca2+ permeant channel.It is later found that TRP channels are expressed broadly in many organisms,tissues and cell types.It is involved in the regulation of sensory conduction and cell signal transduction.Further studies are required to assess which TRPC6(a member of TRPC subfamily) is associated with the cytosolic Ca2+ levels,development and progression of cancer and tumor cell cycle.TRPC6 may be regarded as new targets for the treatment of cancer.
3.Clinical analysis of 20 pregnant women with venous thromboembolic disease
Chinese Journal of Obstetrics and Gynecology 2011;46(12):911-916
Objective To evaluate the clinical features,diagnostic methods and treatment of venous thromboembolic disease (VTE) during pregnancy.Methods From June 2006 to June 2011,a total of 20 pregnant women were diagnosed VTE at the Department of Obsterics and Gynaecology,Qilu Hospital of Shandong University.Clinical data of these patients were analyzed retrospectively.Results (1) Characteristics of patients:the symptoms of all the 20 patients commenced in pregnancy.Of these,6 (30%) happened in the first trimester,7 (35%) in the second trimester,and 7 (35%) in the third trimester.Twelve (60%) patients went to hospital in one week after they had symptoms,while 8(40% ) went to hospital after one week.(2)Clinical manifestation:18 patients were diagnosed deep venous thrombosis (DVT),one was diagnosed pulmonary embolism (PE).One patient was diagnosed DVT and PE simultaneously.Among the 19 DVT patients,16 (16/19)were on the left side,3 (3/19)were on the other.They all came with sudden swelling and pain of the affected lower extremity.In 17(17/19) patients,the circumference differences between two legs were beyond (4.0 ±0.5) cm.In all the 20 patients,12 (60%) had elevated plasma level of D-dimmer.The diagnosis of DVT was made mainly by a Doppler ultrasound.Among the 19 DVT events,7 (7/19) were proximal DVT,2 (2/19) were distal,and 10( 10/ 19) were mixed type.(3)Anticoagulant therapy:patients with VTE during pregnancy were treated with low molecular weight heparin (LMWH) (enoxaparin,once 1 mg/kg subcutaneous,twice a day).After delivery,patients were treated with subcutaneous LMWH and warfarin simultaneously for at least 5 days,until the prothrombin time-international normalized ratio ( PT-INR ) was > 2.0 for 24 hours.( 4 ) Thrombolytic therapy:for most patients with VTE,we are against the routine use of thrombolytic therapy,especially before delivery.For patients with acute massive PE,urokinase of 600 000 units intravenously daily was recommended for 3 days.For those patients with DVT whose standard anticoagulation therapy was < 30 days,an inferior vena cava filter(IVCF) placement was recommended before delivery or abortion.If it was ≥30 days,IVCF was not recommended as a routine,and anticoagulant therapy was used 24 hours after delivery.If there was no recurrent DVT or PE,IVCF was retrieved routinely in 12 days.(5)Outcome:among patients treated with LMWH (95%,19/20).Three received IVCF placement,which was retrieved successfully in 12 days,with no interventional complication.All patients recovered well after 2 weeks,and the circumference differences between two legs were within (2.0 ± 0.3 ) cm.Of the 18 patients maintained to the third trimester,17 received anticoagulant therapy,and no abnormal findings were found during antenatal examination.Ten patients received cesarean section (50%,10/20),while 8 had vaginal delivery (40%,8/ 20).Neither neonatal asphyxia nor malformation was observed.The patients were followed-up for 1 - 24 months,no venous thrombus extension was found in 17 cases by Doppler ultrasound,thrombus disappeared in 2 cases of distal DVT after 4 weeks and 8 weeks respectively.By echocardiography,the pulmonary arterial pressure of the 2 patients with PE was found normal 3 months after hospital discharge.There was no maternal death during the study,no recurrent PE or bleeding occured.Conclusions LMWH is safe and effective for VTE during pregnancy.Routine use of thrombolytic therapy is not recommended.VTE in pregnancy is not the absolute indication of termination of pregnancy.The indication of an IVCF placement should be stricter,and a retrievable suprarenal IVCF is recommended under certain circumstances.
5.On the compensation mechanism for urban medical services
Chinese Journal of Hospital Administration 2009;25(5):297-301
Reform on medial service compensation mechanism,as a key point in the heahhcare system reform,runs through the entire reform process.It plays a key role for the establishment and improvement of urban medical care system,medical service system,medical management system and operating system,for its guidance and regulation effects.Such a refonn to build a scientific and perfect compensation model and mechanism will be highly significant for the smooth progress of the new round of healthcare reform and its success in the end.
6.The effect of CsA on the morphology of the liver-the stereological analysis of the hepatic ultrastructure
Chinese Journal of Organ Transplantation 2000;21(6):334-336
Objective To study the effect of CsA in a therapeutic dose on the hepatic ultrastructure in rats.Methods Twenty-four SD rats were divided into 3 groups.The control group was orally administered olive oil,and the other 2 groups were orally given CsA 25 mg/kg and 50 mg/kg daily respectively.After 2 weeks.the liver samples were taken for ultrathin sections.The stereological method was used to quantify some hepatic ultrastructural parameters including volume density (Vv),surface density(Sv),numerical density(Nv) and specific surface(δ).Results CsA caused an increases of Vv and Sv and a decrease of δ in endoplasmic reticulum;a decreases of Vv and Nv in microbody;decreases of Vv in Golgi complex and glycogen inclusions;an increases of Vv and Nv in lipid inclusions.Conclusion CsA in a therapeutic dose could cause the change of hepatic ultrastructure of rat.

10.Influence of brain-derived neutrophic factor on tissue of oxidative stress and cell apoptosis of secondary brain injury after traumatic brain injury in rats
Journal of Chinese Physician 2016;18(2):240-244
Objective To investigate the changes of the level of oxidative stress and cell apoptosis of secondary brain injury after traumatic brain injury,and the influence of brain-derived neutrophic factor on these parameters in rats,as well as its potential mechanisms.Methods A total 84 adult and healthy male rats was divided randomly into 2 groups:control (n =42) and traumatic brain injury (TBI) groups (n =42).The brain-derived neurotrophic factor (BDNF) group was induced using improved Feeney method and was received abdominal injections of BDNF (0.5 μg/μl) immediately after injury,the control group were received abdominal injections with the same dose sodium chloride injection immediately after injury and repeat one time everyday until the rats was killed.Each group was divided into seven subgroups by sacrificed time after injury,those are 1 h,3 h,6 h,12 h,24 h,3 d,and7 d,each subgroup got6 rats.Each subgroup was randomly selected three rats after being killed.The water content,superoxide dismutase (SOD),malonic aldehyde (MDA),and glutathione (GSH) of rats were measured contusion peri tissues brain tissue.Specimens were taken from left three rats of subgroup,which was part of the brain tissue.The expression of NF-κB p65,around the brain tissue with immunohistochemical methods were detected.TdT-mediated dUTP nick-end labeling (TUNEL) method was used to observe the peri cell apoptosis after brain contusion.Results NF-κB p65 was expressed obviously around the lesion in 1h group,and strongly expressed in TBI-3 h-12 h,and reached a peak in 24 h after the injury,while NF-κB p65 expression reduced in TBI-3 d-7 d,and still in high expression.NF-κB p65 expression strongly correlated with the degree of cerebral edema (r =0.651,P <0.05).For two groups,NF-κB p65 expression strongly correlated with the level of MDA (r1 =0.947,P <0.01;r2 =0.961,P <0.01).Conclusions Changes of NF-κB protein expression after brain injury were involved in a series of pathological processes of secondary brain injury,such as oxidative stress,and apoptosis,brain-derived neutrophic factor is probably through inhibit oxidative stress levels,control apoptosis,prevent the development of vasogenic cerebral edema,and reduce or mitigate secondary brain injury.
