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.

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.

One of the biggest differences between ordinary undergraduate education and higher vocational education is more emphasis on the cultivation of students' vocational skills so as to adapt to so-cial demand and employment. In order to overcome the deficiencies in current teaching outline of voca-tional education and to change from subject knowledge teaching to applied skill cultivating , medical and health curriculum standard including 'curriculum philosophy, curriculum goal, curriculum content, curriculum implementation' four elements was formulated based on concepts of 'education as base , practice orientation and lifelong learning' and cultivation mode combining industry standard with cur-riculum teaching goal and combing work with study. All measures taken above were aimed at promoting coordinated development of students' knowledge, ability and emotion and satisfying the social demand for talent.

For stage Ⅱ colon cancer patients after surgery,the benefit of adjuvant chemotherapy remains controversial.Several studies indicate that the patients with high-risk stage Ⅱ colon cancer can benefit from adjuvant chemotherapy after surgery.According to the clinical and pathological features,the stage Ⅱcolon cancer patients including T4 lesion,perforation,peritumoral lymphovascular invasion can benefit from the adjuvant chemotherapy of oxaliplatin.In the horizontal of molecular and genetic levels,the stage Ⅱ colon cancer patients can express high microsatellite instability (MSI-H) and cannot benefit from the chemotherapy of Fluorouracil.The guiding functions of 18q loss of heterozygosity (18q LOH),Cx43 and gene expression profiling in adjuvant chemotherapy are still unclear,and need further study.

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.

Patients with advanced gastric cancer lose the surgical indications.Chemotherapy can improve the overall survival and quality of life,which is the main treatment option.But there is no standard chemotherapy regimen for the patients with advanced gastric cancer.Since its initial approval,S-1 is widely used in gastric cancer.Several studies were performed to explore combinations of S-1 with other cytotoxic drugs such as platinum,docetaxel,paclitaxel,and irinotecan.All these combinations were found to be promising,with response rates of around 40％-50％ and relatively favorable safety profiles.

Genome sequencing and bioinformatics is driving the discovery of drug targets and development of novel classes of broad spectrum antimicrobial compounds. The analysis of the complete genome sequences of microorganism available in the public databases offers the first insights into the drug targets discovery. This review discusses the use of genomic information in the finding of target genes for antimicrobial drug discovery.

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.

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.
