Objective To discuss the application value of the Nickel-Titanium patella concentrator(NT-PC) in surgical treatment of patellar fracture.Methods A retrospective analysis was made on clinical data of 32 cases of patellar fracture treated with the NT-PC in this hospital from January 2001 to December 2003.Results Re-examination of radiography at 12 weeks after surgery showed bone union was achieved in all the cases,with a smooth patellofemoral articular surface.The patella was preserved completely in all the comminuted fracture cases.According to the Lu's criteria,excellent and good outcomes were achieved in 26 and 6 cases,respectively,the rate of excellent or good results being 100%.The NT-PC was removed at 4 months ~ 2 years(mean,14 months) postoperatively without complications.Conclusions Application of NT-PC in the treatment of patellar fracture can preserve the comminuted patella completely,facilitate the reduction and fixation of the patellofemoral articular surface,and make early postoperative motions available.It is worthy of being recommended.

OBJECTIVE:To evaluate therapeutic efficacy and safety of chemotherapy combined with Xiaoaiping injection in the treatment of elderly patients with advanced gastric cancer. METHODS:60 elderly patients with advanced gastric cancer were collected from our department during 2012-2014,and then divided into union group and single group with 30 cases in each group. Single group was given irinotecan(CPT-11)150 mg/m2 added into 0.9%Sodium Chloride injection,and union group was addition-ally given Xiaoaiping injection 80 ml,qd,on the basis of single group. A treatment course lasted for 14 days,and both groups re-ceived 4 courses of treatment. The tumor markers,disease single rate,progression-free survival (PFS) and the incidence of ADR were compared between 2 groups. RESULTS:After treatment,the levels of CEA,CA199 and CA242 in 2 groups were significant-ly lower than before;the union group was significantly lower than the single group,with statistical significance(P<0.05). The dis-ease single rate of union group was 70.00%,which was significantly higher than that of single group (33.33%). PFS of union group was(11.23±2.17)months,which was significantly longer that of single group [(9.36±0.84)months],with statistical signif-icance(P<0.05). The incidence of leucopenia,alanine aminotransferase elevation,diarrhea,stomatitis and hand-foot syndrome in union group was significantly lower than in single group,with statistical significance(P<0.05). CONCLUSIONS:Xiaoaiping in-jection combined with irinotecan chemotherapy for advanced gastric cancer has obvious effect with a low incidence of ADR.

[ Objective ] To explore the relationship between outpatients amount and climate in Guangzhou City. [Methods] Correlation regression analysis of the relationship between monthly outpatients amount and simultaneous meteorological indexes was carried out in various departments of three hospitals of Guangzhou from the year of 1993 to 2001. [Results] The main meteorological factors affecting monthly outpatients amount are: monthly average atmospheric pressure, monthly lowest temperature, monthly sunshine hours, monthly rainfall, monthly relative humidity and monthly average wind speed. Monthly average atmospheric pressure, monthly lowest temperature, monthly relative humidity and monthly average wind speed are negatively correlated with monthly outpatients amount while monthly sunshine hours and monthly rainfall are positively correlated. Then the corresponding multivariate linear regression equations are established. The results of analysis showed that the main meteorological indexes which were related to the occurrence of diseases are the above six. [Conclusion] The corresponding multivariate linear regression equations can be used to forecast the epidemic trend of diseases in an area and this will provide evidences for the forecast of occurrence and prevalence of diseases.

Objective To study the effect of angelica polysaccharides (APS) on recoverable ability from cryopreservation damage of umbilical cord blood (UCB) hematopoietic cells and APS with hematopoietic growth factors (HGFs) on in vitro expansion of UCB mononuclear cells (MNC) after thawing. Methods Thawed UCB MNC were cultured 24 h or 14 d with various concentration of APS (0,50,100,200,and 400 ?g/mL) or with APS and HGFs. The MNC counting assay,typan blue exclusion assay,colorimetric MTT assay for cell proliferation,CFU-Mix colong-forming assay,and flow cytometry for CD34+ cell rate were detected. Results After adding certain concentration APS in thawed UCB cells,the number of MNC,the rate of trypan blue exclusion,the proliferation of MNC,and the colony production of CFU-Mix were significantly enhanced (P

BACKGROUND:There are no unified methods to isolate,culture and amplify bone marrow mesenchymal stem cells(BMSCs) . Endothelial progenitor cells(EPCs) can be harvested by inducing peripheral blood or bone marrow mononuclear cells. However,the method of collecting bone marrow mononuclear cells is various,and the isolation efficiency is different. OBJECTIVE:To isolate and identify BMSCs and EPCs in vitro. DESIGN,TIME AND SETTING:The cytological in vitro study was performed at the Central Laboratory,First Affiliated Hospital,Anhui Medical University from October 2008 to February 2009. MATERIALS:Two clean healthy male Sprague Dawley rats were supplied by the Anhui Animal Center. METHODS:Rat bone marrow was extracted to harvest mononuclear cells by density gradient centrifugation. BMSCs were isolated by the differential adhesion. Following 48 hours of primary culture of BMSCs,non-adhered cells were collected and induced by EGM-2 complete medium supplemented with fetal bovine serum,vascular endothelial growth factor,fibroblast growth factor,insulin-like growth factor-1 and recombinant human epidermal growth factor. There were three groups:early adherence + common culture EPCs,twice adherence + induction culture EPCs,and rat mature aorta EPCs. Nitric oxide content was directly measured in the medium using nitrate reductase method. MAIN OUTCOME MEASURES:The following parameters were measured:in vitro culture of BMSCs and EPCs,and nitric oxide content in the medium. RESULTS:Primary culture of BMSCs was in a spindle-shape,within 24 hours the majority of cells were adherent,9-10 days up to 90% cells were confluent. Purified BMSCs were amplified and uniform,long spindle,with the passage cycle for 8 days. Flow cytometry detection showed that cells were CD34-,CD45-negative and CD105-positive. Second adherent of EPCs induced by 3 days culture showed colony formation following six days,appeared cord-like structure and microvessel-like growth at 8-10 days. At 2 weeks,the majority of cells were polygonal,colony-forming unit was interconnected,showing a typical "cobblestone"-like. At 7-10 days,cells were double stained DiI-acLDL and FITC-UEA-1. Flow cytometry showed Flk-1-positive and CD133-positive. Nitric oxide content was significantly higher in the culture medium compared with the ordinary cultured cells(P
