"Correspondence between nature and human" is the basic thought of ancient Chinese philosophy. It had different meanings at different historical period. In Shang and Zhou dynasty, nature and human were combined together by sorcery; in Han dynasty, "qi" became the link of nature and human; and in Song and Ming dynasty, the link turned to the "Li".The concept of "correspondence between nature and human" improved the formation TCM theory and influenced its development for all the time.

Objective:To investigate the relationship of CXCR4,VEGF-C and SDF-1 in human laryngeal carcinoma and discuss the significance of the three indexs in lymph node metastasis.Methods:The expression of CXCR4,VEGF-C and SDF-1 was detected by reverse transcription polymerase chain reaction(RT-PCR)and immuno-histochemical SP in 10 cases of adjacent normal tissue,45 cases of laryngeal carcinoma tissue and cervical lymph node tissue.Results:Not in the mRNA but the level of proteins,The positive rate of the expression of CXCR4 and VEGF-C were 78%,67%and 78%,71%in primary tumor cells,were altogether higher than that in adjacent normal tissue(P

Gene-sequencing technique is the most important techniques in the research of modern molecular biology. After decades of development, it has been widely used in disease detection and monitoring due to its high throughput, fast speed and high accuracy. Therefore, the principle and development process of gene-sequencing technique were summarized in this paper, and the principle of gene-sequencing technique of the first generation, the second generation and the third generation and all kind of gene-sequencing equipment based on various principle of technique were systematic introduced in this paper. Besides, the paper also explored and discussed the selection and application of various kind of gene-sequencing equipment in the emergency and early warning monitoring for bacterial infectious disease. On the other hand, the paper also summarized and prospected the application and development of gene-sequencing technique in biology and biomedical research.

Objective:To evaluate the clinical efficacy of combination of Beyond cold light whitening and fluoride-removing material bleaching system for treatment of dental fluorosis. Methods: Seventy-five patients with light, medium and heavy dental fluorosis were randomly divided into three groups. Twenty-five patients with 150 dental fluorosis from the experiment group were treated with Beyond cold light bleaching combined with fluoride-removing material;Twenty-five patients with 148 dental fluorosis from the control group one were treated with Beyond cold light bleaching. Twenty-five patients with 148 dental fluorosis from the control group two were treated with fluoride-removing material. The changes of teeth color were evaluated by Vita shade guide matching after treatment. Results: All of the light dental fluorosis in three groups had good lightening efficacy and 100% bleaching efficacy. The Shade value improvement and overall efficacy of observer group were better than the control groups for the medium and heavy fluorosis(P<0.05). Conclusion: Beyond cold light whitening combined with fluoride-removing material in bleaching is a good method for dental fluorosis bleaching.

Objective:To investigate the effects of indicated concentrations VEGF and DEX on MMP-9 expression and motility of Tca-8113 cell. Methods:Immunohistochemistry and RT-PCR methods were used to detect protein and mRNA changes of MMP-9 in tongue squamous cell with VEGF and DEX treatment. Cell motility was also observed with Transwell incubation.Results:The level of protein and mRNA of MMP-9 as well as cell motility increased with indicated concentrations VEGF(1,5,10 ng/ml) in a dose dependent way(P

Objective:To investigate the effect of clinical pharmacists participating in the drug therapy for the patients with severe bronchial asthma complicated with diabetes. Methods:Clinical pharmacists participated in the treatment process for one patient with severe bronchial asthma complicated with diabetes. Pharmacists analyzed and intervened the therapeutic regimen, performed pharma-ceutical care and provided pharmacy education. Results:The suggestions of treatment and care proposed by clinical pharmacists were a-dopted by clinics. The pharmaceutical care performed by clinical pharmacists could contribute to the disease control and the reduction of the incidence of adverse reactions. Conclusion:Clinical pharmacists can use their pharmaceutical knowledge to provide individual-ized pharmaceutical care and play an important role in improving the safety and efficacy of medication.

Objective To evaluate the prognostic value of enhanced CURB and CURB-65 score in patients with community acquired pneumonia.Methods A retrospective study was conducted among 555 patients with community-acquired pneumonia recruited.According to the patient's 28 day outcome, they were divided into effective group(n=510, 57 cured and 453 improved) and ineffective group(n=45, 30 did not improve and 15 died).The prognosis of the two groups was evaluated using the enhanced CURB and CURB-65 score, the sensitivity and specificity of the two scoring methods were compared.Results Compared with the ineffective group, the age, length of hospital stay and the prevalence of the complications of chronic diseases were significantly lower than the effective group(P<0.05).The score of enhanced CURB and CURB-65 of ineffective group were significantly higher than the effective group(P<0.05).The sensitivity of enhanced CURB score was significantly higher than that of CURB-65 (P<0.05) while its specificity was significantly lower than that of CURB-65(P<0.05).Conclusion The CURB and CURB-65 score in community acquired pneumonia can effectively assess the severity of the disease and thus guide the treatment of patients with community acquired pneumonia.

The statistical table is the common presentation way in nursing academic paper? From the standard production of statistical table and combining with editing working practice, this paper analyzed the common usage errors of statistical table with examples in nursing academic papers and put forward some corresponding suggestions?

Objective:To explore the effects of formative assessment using sitcom play in obstetrics and gyne-cology nursing teaching.Methods:Totally 214 undergraduate of grade 2011 nursing students were recruited in the present study.Using envelope method,2 classes were randomly selected as the control group and 2 as the experi-mental group.Students in the control group (n--107) were assessed with traditional assessment method,while those in the experimental group (n =107) were taught using situational drama performance and assessed with form-ative assessment method throughout the process.Students' test scores of obstetrics and gynecology nursing in these two groups were compared,and the opinions on the formative assessment method using sitcom play were investiga-ted among students in the experimental group.Results:Students in the experimental groupscored significantly high-er than those of the control group(78.43 ± 5.21 vs.76.67 ± 6.40,t =2.20,P ＜ 0.05).About 98.31％ of the students approved the formative assessment mode.They reported that this approach was helpful to improve the abili-ty to combine theory and practice andto communicate with others,to cultivate students' creative thinking,and to stimulate their learning interest and learning initiative.Conclusion:The application of formative assessment mode using sitcom play in obstetrics and gynecology nursing teaching is beneficial to enhance teaching effect and improve the ability of nursing students,which is worth popularizing.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains a curable method for hematological malignancies.Nearly all transplant candidates have donor with the successful application of haploidentical SCT.This article summarized some reports on donor selection,prophylaxis and treatment of graft-versus-host disease,and graft failure in the 58th American Society of Hematology Annual Meeting to present the progress of allo-HSCT in treating hematological malignancies.
