Objective To study the adhesion and proliferation of rabbit bone marrow mesenchymal stem cells(BMSCs) on the HA/TCP bone graft scaffold.Methods BMSCs were harvested from the iliac bone and obtained by using adhesive culture method.BMSCs were induced with osteogenic medium,at the 7th day,the cells were stained by the calcium cobalt method to show the activities of alkaline phosphatase(ALP).At the 10th day,the mineralized nodules of osteoblasts stained with chinalizarin.Otherwise BMSCs were induced with adipogenic medium,and at the 21st day the cells stained with oil red O.We cultured the BMSCs on the surface of a matrix scaffold with osteogenic medium.The morphologic characters were checked by light microscopy,fluorescence microscopy and scanning electronic microscopy,and the proliferation of BMSCs were assayed using the MTT test.Results At the 7th day after osteoblastic induction,ALP was strongly positive,and at the 10th day,mineralized nodules stained with chinalizarin were jacinth.At the 21th day after adipogenic induction,the adipocytes were stained with oil red O.BMSCs grew well around or in pores of the HA/TCP bone graft scaffold and could be seen using both fluorescence microscopy and scanning electron microscopy.The MTT test assay showed that the HA/TCP couldn't inhibit the proliferation of BMSCs.Conclusion BMSCs have a good biocompatibility with a HA/TCP bone graft scaffold.

ObjectiveTo evaluate the clinical efficacy and toxicity of the regimen of paclitaxel combined with gemcitabine for anthracycine-resistant metastatic breast cancer. MethodsThirty patients with anthracycine-resistant metastatic breast cancer were enrolled in the study: paclitaxel 135mg/m2 infusion on day 1; Gemcitabine 850mg/m2 infusion on day 1,8 ,and administered in three weeks cycle. The clinical efficacy was evaluated every two cycles. ResultsOf all thirty patients qualified for efficacy analysis and among them CR 3 cases( 10％ ) ,PR 11 cases (36.7 ％ ), SD 11 cases ( 36.7％ ), and PD 5 cases ( 16.7％ ), with an overall response rate of 46.7％. The median TTP and overall survival in those 30 patients was 7.1 and 15.6 months. The main toxicities with grade 3 and 4 were hypoleucocytosis in 10 patients(30.0％ ) ,thrombocytopenia in 4 patients( 13.3％ ). ConclusionThe regimen of paclitaxel combined with gemcitabine was effective,well-tolerated scheme in the anthracycine-resistant metastatic breast cancer.

The pathogenesis of ulcerative colitis (UC) is spleen-stomach weakness with dampness. Therefore, Qu-Shi (QS, eliminating dampness) is the main treatment principle. According to different pathogens, four QS methods in the UC treatment were summarized based on clinical experiences. In the clinic , the application of heat-clearing and dampness-eliminating, warm yang and dampness-eliminating, dampness-eliminating with bitter and pungent, spleen-reinforcing and dampness-eliminating. The indications should be identified for the application of principle-method-prescription-medicine. The flexible application of four methods mentioned above can increase the clinical efficacy.

Biliary-pancreatic-duodenal junction is a special region in the human body.It is difficult to diagnose and treat diseases in this region because of the complicated anatomy,the limitation of diagnosing methods,the variety of disease,the high risks of operation and the severity of complications. We should pay more attention to the pathophysiology aspects and the laboratory researches of diseases in this region.Proper diagnosis and combination of different diagnosing methods could improve the rate of early diagnosis and identify the characteristics of the disease. Individualized operation should be considered to deal with iatrogenic injury of biliary-pancreatic-duodenal junction according to different patients' condition.The principle of operation is to control damage firstly and to preserve the function of biliary-pancreatic-duodenal junction and the physiological passway of bile and pancreatic juice to the greatest extent.

Objective To study the dinical value of serum soluble E-selectin(sE-selectin)and serum soluble P-selectin(sp-selectin)in patients with esophageal squamous cell carcinoma. MethodsThe sP-selectin and sP-selectin of the serum was measured by ELISA in 27 patients with viral encephalitis and 35 normal persons. ResultsIn patients with organ metastasissE-selectin and sP-selectin levels were significantly higher than normal(P＜0.01),In patients with organ metastasis,sE-selectin and sP-selectin levels increased more pronounced.No visceral metastasis in patients with esophageal cancer,postoperative serum sE-selectin and sP-selectin levels significantly decreased compared with the preoperative(P＜0.01),there are organ metastasis in patients with esophageal cancer sE-selectin and sP-selectin levels decreased not obvious. ConclusionsE-selectin and sP-selectin could be used as a new tumor detection of esophageal cancer targets,and has close relatimship with the incidence of esophageal cancer,development and metastasis.

Iatrogenic injury in choledocho-pancreatico-duodenal junction is usually difficult to discover in the course of operation because of its unique anatomical position. The injury can lead to postoperative chilis, fever, pain and swelling of the waist, which would easily be misdiagnosed as acute necrotizing pancreatitis. Controlling operations, such as bile and pancreatic juice separation, duodenal diverticularization, jejunal fistulation for enteral nutrition and abdominal drainage should be performed in dealing with the injury in choledocho-pancreatico-duodenal junction. Combined application of pyloric suture with absorbable thread and ligatian, gastric fistulation, ligation of the distal common bile duct and T-tube drainage is minimally invasive, and can fulfill a fully separation of bile and pancreatic juice and duodenal diverticularization. It will improve the possibility of secondary radical operation by ameliorating pyemia and general nutritional condition.

Objective To set a RFID(Radio Frequency Identification) system for Gold Immunochromatographic Assay by using RFID-reading module,RFID tags and the master-MCU.Methods Radio frequency technology is characterized by the automatic identification and large dada-storage capacity.Electronic tags were packed with Gold Immunochromatographic Assay(GICA) strips and such data were stored in electronic tags as strip information,the test results,the identity of the tested,the test date,etc.The information were transmitted to PC through the RS-232 serial port,thus realizing the rapid and accurate recording and management of data.Results The application of RFID guaranteed the proper use of Gold Immunochromatographic Assay strips and improved the efficiency of sample management and data storage.Conclusion The application of RFID to Gold Immunochromatographic Assay can be used in general investigation of epidemic situation,biomedical detection and other relevant fields.

Objective To study the quality control method of Shaolin Zhenggujing tincture. Methods Angelicae Pubescentis Radix and Angelicae Sinensis Radix in the preparation were identified by TLC. The content of dracorhodin, the effective component of Resina Draconis, was determined by HPLC with acetonitrile-0.05 mol/L sodium dihydrogen phosphate (50∶50) as a mobile phase and 440 nm as the detection wavelength. Results Characteristic spots of TLC were clear with strong specificity and the negative test showed no interference. There was a good linear relationship for dracorhodin in the range of 3.997-43.97 ng and the recovery was 101.26% (RSD=2.84%). Concludion The qualitative and quantitative methods are accurate, reliable and repeatable, it can effectively control the inner quality of Shaolin Zhenggujing tincture.
