OBJECTIVE To discuss about the influence of the monograph Treatise on Pestilence(Wenyilun) dealing with infectious disease on traditional Chinese medicine(TCM).It was the first time alternatively to describe about infectious disease in etiology,pathogenesis and treatment by TCM way. METHODS In etiology,it was described Zaqi(a special pathogenic factor) to cause infectious epidemic disease,not by general six pathogenic factors.It was similar with modern medicine in etiology.In pathology,it was analyzed and differentiated the developing of an epidemic febrile disease treatment with Qi and Xue.In treatment,it used elimination treatment method including diaphoresis,inducing emesis,and purgation therapy. RESULTS Since then a new science of epidemic febrile disease of TCM was gradually formed. CONCLUSIONS This new theory has deeply influenced in the analysis and differentiation and treatment of epidemic febrile disease.Now theory on epidemis febrile disease of TCM is becoming a systemic and comprehensive doctrine about infectious disease treatment in modern Chinese medicine.

Objective To investigate the expression of surfactant protein A(SP-A)in adenocarcinoma and squamous cell carcinoma of lung and its clinical significance.Methods The expression of SP-A was determined by immunohistochemical assay (EnVision) in 27 cases of adenocarcinoma,15 cases of squamous cell carcinoma of lung.Then the association of SP-A expression with clinicopathological parameters was analyzed.Results The expression rate of SP-A was significantly higher in adenocarcinoma of lung than that in squamous cell carcinoma of lung(51.85% vs 6.67%,P<0.01).The expression rate of SP-A in papillary adenocarcinoma,bronchioloalveolar carcinoma,acinar adenocarcinoma and musinous adenocarcinoma of lung was respectively 85.71%,50%,40%and 25%.There was no correlation between the expression of SP-A and gender,age,tumor size and lymph node metastasia.Conclusion The expression of SP-A may be associated with histological types of the lung carcinoma,which may be used as important marker in differential diagnosis of adenocarcinoma and squamous cell carcinoma of lung.

Objective:To investigate the efficacy of montelukast in the treatment of children with asthma and its influence on the serum levels of metalloprotease-9 (MMP-9) and metal protease inhibitor-1 (TIMP-1).Methods:Totally 90 cases of asthma children were selected and divided into the control group and the observation group with 45 ones in each .The control group was treated with the conventional symptomatic treatment , and the observation group was treated with montelukast chewable tablets additionally , and the treatment course was 8w.The effectiveness adverse reactions were compared between the groups , and the lung function indices and the changes of MMP-9 and TIMP-1 levels of the two groups were compared as well .Results: The total effective rate of the observation group (93.33%) was significantly better than that of the control group (P<0.05).After the treatment, the levels of FEV1 and PEF were significantly higher than those before the treatment in the two groups , the levels of MMP-9 and TIMP-1 were notably lower than those before the treatment in both groups , and the changes in the observation group were more significant than those in the control group (P<0.05).There were no adverse drug reactions in both groups .Conclusion:Montelukast combined with the conventional therapy can down-regulate the serum levels of MMP-9 and TIMP-1 and inhibit airway remodeling resulting in improved curative effect with high safety.

Objective To search the status quo of students'thanatopsis in order to push focused education on terminal care to the nursing major students.Metheds To distribute home-made questionnaire to 268 nursing students.Results students who cannot talk about death normally account for 21.3 percent;who never considered death or unnecessary to consider death account for 12.9 percent of the total;who considered a lot account for 10 percent;who cannot handle terminally ill account for 74.3 percent;and who prefer self-suicide when suffered defeat account for 4.9 percent.Conclusion Nursing students have insufficient ideas of death,and they need to think deeply about the meaning of death and to nurture a positive outlook on death in order to get a correct terminal care education.

Objective To study the clinical application of low molecular weight heparin combined with psychological intervention in the prevention of deep venous thrombosis after lower limb fracture surgery.Methods 100 patients with lower limb fracture treated in our hospital from January 2013 to December 2016 were selected as the research object in the course of the study, and randomly divided into control group and experimental group, with 50 cases in each group,.The patients in control group were treated with routine lower limb physical pressure to prevent deep venous thrombosis after lower limb fracture.The patients in the experimental group were treated with low molecular heparin combined with psychological intervention to prevent deep vein thrombosis after lower limb fracture.Comparative analysis of patients with prothrombin time and platelet and the experimental group and the control of activated partial thromboplastin time index.Results After different treatment, the platelet index of the experimental group was(189.23±36.23)×109 /L, significantly better than that of the control group(264.34±39.56)×109/L,the difference was statistically significant(P<0.05).After treatment, the patients in the experimental group the activated partial thromboplastin time and prothrombin time index respectively(35.62±4.23)s and(16.12±2.19)s, significantly better than the control group, the difference was statistically significant(P<0.05).Conclusion low molecular weight heparin combined with application of psychological intervention in prevention of deep venous thrombosis after lower limb fracture surgery, can improve clinical curative effect on prevention of deep vein thrombosis in a large extent, improve blood hypercoagulable state of patients after surgery, with further clinical promotion and application significance.

Objective:To observe the effects of osteoprotegerin on osteoclasts in the occlusal tissue during tooth eruption in dog and analyze the mechanism. Methods: Six 7-day-old brood dogs were divided randomly to control and osteoprotegerin groups. The dogs in osteoprotegerin group were injected with osteoprotegerin for 3 days 1.5 mg/(kg?d). 5 days after injection the dogs were sacrificed and mandible were taken out for paraffin slice. The number of the osteoclasts in the occlusal tissue up the third mandibular premolar was detected by tartrate-resistance acid phosphatase(TRAP) staining. Immunohistochemistry was used to examine the expressions of RANKL. Results: The number of osteoclasts in osteoprotegerin group was less than that in the control group (P

AIM: To investigate the protective effects of quercetin on nephrotoxicity induced by cyclosporine A(CsA)in rats. METHODS: Male Sprague-Dawley (SD) rats were divided into four groups of seven rats each. Control group, quercetin (40 mg/kg) group, CsA (40mg/kg) group, CsA (40 mg/kg) plus quercetin (40 mg/kg) group. The all groups were administered once day respectively for 15 days. Twenty-four hour urines were collected at the 10th and 14th day respectively after administration to measure the content of urinary protein and urinary N-acetyl-?-D-glucosaminidase(NAG). The animals in all groups were sacrificed 4 h after the last administration. Blood samples were collected to measure serum creatinine(SCr), blood urea nitrogen(BUN). Kidneys were removed rapidly, excised and sectioned for histological analysis. Other kiney tissues were utilized for biochemical analysis. RESULTS: Quercetin prevented urinary protein, SCr, BUN, NAG, and kidneys histological alterations.Quercetin significantly decreased malondialdehyde(MDA) content while significantly increased glutathione(GSH) content and glutathione-S-transferase(GST), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase(CAT) activities of kidneys tissues in the rats treated with CsA. CONCLUSION: Quercetin can effectively attenuate the nephrotoxicity induced by CsA.
