Colorectal cancer is one of the most common malignancies in the world, and rectal cancer accounts for a large percentage of this disease in Chinese patients. Surgical extirpation is the mainstay of therapy, Intraluminal ultrasound is highly accurate in detecting depth of invasion and lymph node metastasis, and is also helpful in preoperative staging of rectal cancer. Preoperative adjuvant therapy could down-stage tumors, improve the radical resection rates of advanced lower rectal cancer, increase the rate of sphincter-saving surgery, and decrease the local recurrence rate. Total mesorectal excision could signifi-candy decrease the local metastasis of rectal cancer, and rectal cancer resection with preservation of pelvic autonomic nerve is effective in preventing urinary or reproductive dysfunction. Recently, minimally invasive surgery has been introduced for the management of rectal cancer, and transanal endoscopic microsurgery is a new method with advantages in rectal cancer treatment.

Objeetive To analyze the risk factors on anastomotic leakage after low anterior resection with the technique of total mesorectal excision(TME)for rectal carcinoma. Methods Our retrospective study included 498 patients of rectal cancer who underwent anterior resection with TME technique. Results 7.2%patients(36/498)developed clinical anastomotic leakage.Sex,distance of tumor from anal verge,preoperative radiotherapy were found related to the anastomotic leakage ( P＜0.05 or0.01),while age,diabetes,hypertensive disease,vesse]emboli,diversion stoma construction,anastomotic technique were not.Among the 37 patients with diversion stoma construction simultaneously,3 patients developed leakage who recovered conservatively.Among the other 33 leakages 10 were cured conservatively.The other 23 leakages necessitated a laparotomy and proximal colostomy. Conclusion Sex,distance of tumor from anal verge,preoperative radiotherapy were risk factors for anastomotic leakage after TME.

Objective To prove the application of bilingual teaching in the child health care curriculum. MethodsEnglish dubbing and Chinese subtitling DVD coursewares of child growth and development were played to medical interns.The interns were asked to do questionnaires to examine feasibility and effectiveness. Results In 8-year program medical students,77.8% of them and 64.8% of the 5-year nutrition professional students could understand the contents of more than 90%.If there was no Chinese subtitles,the ratio were only 5.6% and 6.4%.Most students preferred English subtitles and dubbing,and endorsed the model of bilingual teaching. Conclusion DVD coursewares with Chinese subtitles and English dubbing can be widely used in the teaching of child health care.

Objective To access the clinical effectiveness and safety of the home-made coronary artery stent - Jin Xin stent. Methods Ten patients with coronary heart disease,from 39 to 70 years old (averaged 55 2yrs),male 7,female 3,were performed PTCA .Jin Xin stents were implanted in to left anterior descending arteries(2),left circumflex(3)and right coronary arteries (5). Results The stenosis was 80～100% before the stents implantation, and 0 after the implantation. There were no abrupt occlusion and thrombosis during the procedure,and no cardiac events during the 6～8 months follow-up. Conclusion Jin Xin Stent is very good at releasing and standing-support. And it can dilate completely. It is safe and effective as an interventional therapy for coronary heart disease.

Objective We Observed the mobilization effects of autologous circulating blood stem cell by G-CSF in old patients(≥70 years old) with acute myocardial infarction (AMI).Methods 10 old patients with AMI were allocated to receive either inclusive type Granulocyte Colony-Stimulating Factor (G-CSF), or excrete type G-CSF to mobilize the stem cell, with either 300?g/day or 600?g/day. The patients received G-CSF by hypodermic injection, and the duration of applying G-CSF was 5 days. In the process of the mobilization of the circulating blood stem cell, the white blood cell (WBC) and CD34 + cell count in the circulating blood should be observed. Results Prior to applying G-CSF and the 3rd、4th、5th、6th、7th after applying G-CSF, the counts of WBC were 6.75?10 9/L、28.16?10 9/L、34.93?10 9/L、34.40?10 9/L、38.93?10 9/L、21.85?10 9/L; the counts of CD34+ cell were 6.25?10 6、51.10?10 6、92.60?10 6、109.65?10 6、134.69?10 6、45.09?10 6 The peak of curve that WBC and CD34 + cell count changed with applying days was at the 6th .The count of CD34 + cell in the circulating blood was positive referent with the count of WBC in the circulating blood(r=0.940)Conclusion In old patients with AMI, the mobilized peak of WBC and CD34 + cell counts changed with applying days was at the 6th, and the count of CD34 + cell in the circulating blood was positive referent with the count of WBC in the circulating blood.

Objective To observe the safety and feasibility of autologous peripheral blood stem cell (PBSC) transplantation by intracoronory infusion in patients with acute myocardial infarction (AMI).Methods Totally 27 patients with AMI were randomly allocated to receive either inclusive type granulocyte colony-stimulating factor (G-CSF),or excretory type G-CSF to mobilize the stem cells.They received the dose of G-CSF 300-600?g/d by hypodermic injection for 5 days.On the sixth day,PBSCs were separated by Baxter CS 3000 blood cell separator into 50ml suspending liquid.The suspending liquid without treatment was infused into the infarct-related artery (IRA)by occluding the over-the-wire balloon and infusing artery through balloon center lumen.During PBSC mobilization,the following side-effects should be paid attention to,such as bone pain,lethargy,tetter,fever,gastrointestinal effects (nausea,vomiting,constipation),angina or deteriorated heart failure,as well as some rare complications (spontaneous spleen rupture,severe purulent infection, hypercoagulable state,and autoimmune diseases).When the PBSCs were being separated and collected,some complications were observed,for example,low calcium effects (mouth numbness and spasm),pale and dizziness due to vagus reflect,pale and dizziness owing to low blood volume,deterioration of angina or heart failure.The complications should also be observed during the PBSC transplantation by intracoronary infusion:arrhythmia including bradycardia (because of balloon occlusion),sinus arrest or the third degree of atrial ventricular block (because of coronary spasm due to balloon stimulating stent), ventricular fibrillation or hypotension,etc.Results There were 22 cases with complications during the mobilization,separation,collection, and infusion of PBSCs.The incidence of complications during mobilization was 44.4%(12/27),during separation and collection is 25.9%(7/27),and during PBSC transplantation by intracoronary infusion 11.1%(3/27).Conclusion In patients with AMI,Intracoronary infusion of PBSC is feasible and safe.

Objective To develop a method for the determination of ganciclover in human plasma by RPHPLC.Methods Plasma containing ganciclover was extracted with methanol and methylene chloride,qualitative and quantitative analysis was carried out directly.Working curve,linear range,recovery,precision and so on was obtained according to the sample pre-processing method and analysis state.The HPLC method has been taken to investigate the plasma concentration of ganciclover for 12 volunteers.Results The relationship of the peak area of ganciclover concentration in plasma linear within the range of 0.05 μg/mL～1.60 μg/mL(r=0.9999).The lowest detection limit was 0.01 μg/mL(S/N≥13).The intra and inter-day RSD were less than 5.1%respectively.The recovery is about 90.0%～95.4%.Conclusion The established method in the article was shown to be sensitive,accurate and simple for the determination of ganciclover level.It is suitable for clinical detection of ganciclover and forensic medicine and toxicology analysis.
