Objective To assess the feasibility of secondary check by LinaTech TiGRT treatment planning systems.Methods Choosing the Linatech TiGRT treatment planning system,researched and developed by Linatech company,as the third-party check tools.First,using Linatech TPS for recomputing treatment plans for geometrical phantoms designed in TG-119 and patients.after computation,compared the point dose with the measured data of phantoms (Using chameber No.2571 to measure point dose) and original plans.Using PTW verisoft with a criteria of 3% dose difference and 5 mm distance to agreement to assess the dose distribution on center level.After then,you can assess the accuracy of treatment plans.Results Tiny volume changes were found in ROI,especially in small size phantoms orcuspidal regions.For comparing measured data with recomputed plans and original plans,the dose data were found basically identical in TG-119 phantoms.And for patients,the differences between recomputed plans and AAA original plans or AXB original plans were smaller in breast cancer,but they were even bigger innasopharynx cancer,all patient cases showed a gamma passing rate more than 90%.The gamma passing rate of AAA original plans and AXB original plans were 95.6% and 97.53% for breast cancer,and 94.67% and 96.83% for nasopharynx cancer.Conclusions The method of utilizing the LinaTech TiGRT treatment planning system as a third-party check tools to assess the accuracy of plans is feasible,and the validation process is convenient,but some functions still need to improve and the scope of differences still need more patient cases to determine.

To investigate the immunological activities of the recombinant human phosphatase D2 (rhPLD2) in vitro and in vivo, especially its ability to reduce inflammatory reactions, the cDNA fragment encoding rhPLD2 was cloned into prokaryotic expression vector pET30a by RT-PCR and the recombinant protein rhPLD2 expressed in E.coli was purified from the inclusion bodies, while the anti inflammatory activity of rhPLD2 was determined by the amount of eosinophils in bronchoalveolar fluid(BALF) and blood and the expression of IL-5 and MMP-9 in lung tissues of guinea pig model of chronic asthma. It was found that the rhPLD2 recombinant protein was obtained from human Daudi cells by cloning to E.coli, which contained no membrane-binding site and signal peptide. The cDNA sequence encoded 631 amino acid residues (GenBank Accession Number: AY178289). The purity of the rhPLD2 approached up to 76% with a bioactivity of 50.9745 units/L (0.9212 g/L). In addition, the anti inflammatory effect of rhPLD2 protein could be demonstrated in the guinea pig model of chronic asthma after treatment with rhPLD2 protein, such as down regulation in the expression of the inflammatory cytokine IL-5. It is concluded that the anti-inflammator activity of the recombinant human truncated PLD2 protein produced from the E.coli plasmid can be demonstrated both in vitro and in vivo.

Objective To observe the serum levels of homocysteine (Hcy) and hypersensitivity C-reactive protein(hs-CRP) in elderly patients with cerebral infarction and to investigate their relationship and clinical significance by National Institutes of Health Stroke Scale (NIHSS).Methods The serum levels of Hcy and hs-CRP were by enzymatic cycling method and scattering turbidimetry in the elderly patients ( 116 cases with cerebral infarction and 100 cases of healthy control).Those 116 cases with cerebral infarction were divided into three groups by the degree of NIHSS.The three groups were compared with each other.Results The levels of serum Hcy and hs-CRP in elderly patients with cerebral infarction were significantly higher than that of healthy control group ( t =6.97,P ＜0.01 ; t =14.96,P ＜0.01 ).There has significant difference among those three groups with cerebral infarction by comparing with each other( F =23.49,P ＜0.05; F =28.19,P ＜0.05).A positive correlation was found between Hcy and degree of NIHSS( r=0.54,P ＜0.05),and between hs-CRPand degree of NIHSS( r =0.58,P ＜0.05).Conclusions Serum levels of Hcy and hs-CRP are correlated with the occurrence of cerebral infarction and its severity.There has positive clinical significance to evaluate the effect of cerebral infarction by measuring the serum levels of Hcy and hs-CRP dynamic.

Objective This study evaluated the effects of combined procedure of surgical treatment and cell transplantation on dilated cardiomyopathy. Methods Eight patients (5 men and 3 women) with moderate to severe mitral regurgitation from end-stage dilated cardiomyopathy underwent surgery. Four patients were in functional class (FC) Ⅳ, six were in FC Ⅲ. There age ranged from 15 to 56 years. The preoperative ejection fraction (EF) ranged from 0.15 to 0.32 (mean 0.26 ± 0.08). Mitral valve replacement was performed in 5 patients and mitral valve repair in 3. Auto-bone marrow monenuclear cells were harvested, isolated, washed, and resuspended for direct injection after surgical procedure. Results All patients survived and were discharged from the hospital. After a mean follow-up period of 18 months ( 12 - 42 months). Echocardiography showed postoperative ejection fraction and wall movement velocity increased after 6 months. Radionuclide ventriculography showed myocardial perfusion improved significantly. Conclusion Combined procedure of surgical treatment and cell transplantation led to significant improvement in cardiac function in patients with dilated cardiomyopathy.

Objective To investigate the effect of potassium channel blocker tetraethtylamine (TEA) on the proliferation and apoptosis of human laryngeal carcinoma cells (Hep-2) through the PI3K/Akt signaling pathway.Methods TEA acted on HEp-2.The methyl thiazolyl blue (MTT) method was used to determine the Hep-2 cell activity and the proliferation inhibition rate of TEA on Hep-2 was calculated;the Hoechest33258 staining was used to detect cell apoptosis,and the Hep-2 apoptosis rate was detected by flow cytometry (FCM) assay.Results After inoculation by 5,10,20 mmol/L TEA,the Hep-2 cell proliferation inhibition rate reached 12.573%,31.385% and 56.132%,respectively.After 96 h Hep-2 cell action,the cellular apoptosis rates were (41.64±2.67)%,(58.76±4.32)% and (72.65±6.54)% respectively,the inhibition rate and apoptosis rate in the TEA treating group were significantly higher than those in the non-TEA treating group,the differences were statistically significant (P<0.05).Conclusion TEA can inhibit the proliferation and in vivo growth of human laryngeal carcinoma cells and promotes the apoptosis of laryngeal cancer cells.

Objective To provide evidences for rational use of antibiotics in treatment of hospital-acquired urinary tract infection.Methods The bacteria isolated from mid-stream urine samples were collected for susceptibility test(MIC)using international standard plate dilution method.According to breakpoints defined in CILS guidelines(2009),each strain of bacteria was determine for susceptibility to antimicrobial agents,and calculated for rates of resistance(R%),intermediate(I%)and susceptibility(R%)to compounds tested.Results 552 strains of bacteria were collected,including 432 strains(78.3%)of Gram-negative bacilli and 120(21.7%)of Gram-positive bacilli;Escherichia coli was one of the most common bacteria in the urinary tract infection(55.3 %),followed by Enterococcus(17.4%).The results of antibiotic susceptibility test in vitro showed that Enterobacteriaceae was 100% susceptible to imipenem;Gram-positive cocci were sensitive most to glycopeptide antibiotics.Conclusion Clinicians should pay attention to the species of pathogenic bacteria causing urinary tract infection and their susceptibility to clinically common used antibiotics for reasonable use of drugs.

Based on the principle of binocular stereopsis, three-dimensional reconstruction of the nucleus isthmus (NI) in the frog (Rana nigromaculata) has been realized by using a microcomputer system. The histological techniques used were somewhat different from conventional ones in that two pin holes, which were regarded as fiducial points to ensure an accurate alignment of the outlines of microstructures in the serial sections during three-dimensional computer reconstructing, were made in the tissue block with a micropipette before it was cut. All operations such as collection of outline-data of the microstructures, data processing and drawing output were all under control of the software. Three-dimensional morphology of NI and its location in the midbrain have been demonstrated by the stereopairs. Its dimensions measured on the basis of the reconstruction is 500 (caudorostal)?810 (dorsoventral)?810 (mediolateral)?m. The significance of three-dimensional computer reconstruction for accurately measuring the dimensions of NI and other biological microstructures and for the study of histological morphology are discussed.
