The study is aimed to provide the theoretical basis for exploiting and utilization of salt-alkaline soil and cultivating Belamcanda chinensis. In this study, we exerted exogenous substances SNP, Spd to relieve the damage of the mixing salt-alkaline stress on B. chinensis seedling which is NaCl, Na2SO4, NaHCO3 and Na2CO3 four kinds of salt molar ratio of 9: 1: 9: 1, salt concentration of 100 mmol x L(-1). The result illustrated that high pH stress is a major factor caused the salt-alkaline stress, the interaction between time and the concentration of each, treatment was observed, what is more, there are synergies between the salt and alkali stress. The content of B. chinensis seedling leaves' membrane peroxidation index (MDA, O2-*) and metabolites (soluble protein, soluble sugars, organic acids) are showing an upward trend in varying degrees under 100 mmol x L(-1) salt-alkaline stress. It is effective to reduce the content of MDA and O2-*. and improve the levels of metabolites, in which the SNP (0.05 mmol x L(-1)) and Spd (0.5 mmol x L(-1)) to alleviate damage effects is the best. Therefore we can hold the conclusion that SNP and Spd can effectively mitigate the damage of B. chinensis seedling on salt-alkaline stress, improve the resistance ability of B. chinensis seedling which can provide the scientific basis for the utilization of salt-alkaline soil, and the cultivation of B. chinensis.

Objective To study the effects of ? carotene on rat liver fibrosis induced by carbon tetrachloride (CCl 4). Methods ① After being treated with CCl 4 for 3 weeks to induce the experimental rat liver fibrosis, rats were treated with ? carotene 250 000 U/kg body weight by oral feeding twice a week. The normal and the CCl 4 control group were also set. ② The liver pathological and ultrastructual change were studied. The content of rat liver hydrooxylproline, the expression of ? 2 (Ⅰ) collagen RNA and transforming growth facter ? 1 (TGF ? 1) were studied at the same time. Results In the treatment group, the liver fibrosis scores were fewer significantly than those in the CCl 4 group ( P

OBJECTIVE To discuss how to strengthen detail management to control hospital infection in operating room. METHODS The consciousness of controlling hospital infection,detail management as the key,integration of daily supervision examination with periodic inspection test and assessment,perfecting the detail management mechanism of hospital infection,and executing operation rules strictly were carried out. RESULTS The knowledge of hospital infection in staff members was improved,working efficiency raised,nursing level increased obviously,and the sterile operation infection rate dropped down. CONCLUSIONS Strengthening detail management is good for hospital infection control in operating room.

In recent years,health economics developed quickly,which attracted both international academic and public interested.Compared with the developed countries,although the study of health economics in China started relatively slow,it has already attracted more and more attention by the academic along with the rapidly social development.With the support from international organizations and academic institutions,China had gradually established its health economics research net from 1990s,the research system had been improved and a serious of research achievements had already playedmore important role in the procedure of government decision making.It summarized the research progress in the field of international and China's health economics so as to provide references for research and policies.

Objective: To learn law students' understanding of and demand for knowledge of forensic medicine,especially their attitude for autopsy and adjust the teaching reform in forensic medicine.Methods: Investigation was made by anonymous questionnaire in law undergraduates of 1999 and 2000 grades in Law College of Shantou University.Results: Almost all the students considered forensic medicine essential for themselves.The antitheist rate of the students in non-Chaoshan area(75.2%) was higher than that of the students in Chaoshan area(54.2%).57.4% of the students didn't want to join autopsy because of dread without obvious causes.93.3% of them thought that the autopsy should be taken by the legal medical experts.Conclusion: The law students prevalently enjoy the courses of forensic medicine,and they are more interested in the knowledge of forensic pathology.

Abstract: To report the diagnosis, treatment and outcome of 4 patients with hematological diseases complicated with Aeromonas hydrophila bloodstream infection in the Second Affiliated Hospital of Kunming Medical University, further clarify the importance of blood culture and deepen the clinical understanding of the disease. Four patients with hematological diseases complicated with Aeromonas hydrophila bloodstream infection treated in the Second Affiliated Hospital of Kunming Medical University from 2017 to 2021 were recruited as the study objects. The clinical manifestations, blood culture collection, detection time of Aeromonas hydrophila, laboratory examination, treatment and prognosis of the patients were retrospectively analyzed. In this study, 4 cases were male patients with hematological diseases, who were in myelosuppression after chemotherapy. After fever, blood culture was collected and Aeromonas hydrophila was detected. The positive time of blood culture in 4 cases ranged from 4 to 11 hours. The results of antibiotic sensitivity showed that it was highly sensitive to the second, third and fourth generation cephalosporins, quinolones and carbapenems. Four patients were treated with imipenem cilastatin sodium in the early stage, and one patient recovered after active anti infection and leukocyte raising treatment. One patient did not complete chemotherapy due to a request for discharged, and the follow-up was unknown. Two patients developed rapidly into necrotizing fasciitis and died later. Hematological diseases complicated with Aeromonas hydrophila bloodstream infection are rare, but the mortality rate is high. For patients with repeated fever and considering infection, blood culture should be carried out as soon as possible to confirm the pathogen and drug sensitivity test. During clinical treatment, the treatment should be adjusted in time in combination with the patient's situation. In addition to anti-infection treatment, the patient's immunity should be improved and the development of necrotizing fasciitis should be vigilant.

Objective To explore the mechanism of blood-stage treatment in patients with psoriasis vulgaris through studying the level change of IFN-?, IL-4, IL-10 and IL-17 in patients with blood-stage treatment during activity and quiescence period separately. Methods 20 patients with psoriasis vulgaris in active stage(blood heat syndrome)and 20 patients with psoriasis vulgaris in resting stage(blood stasis syndrome) were recruitedto observe the treatment effects by the PASI score,and to observe thechange of IFN-?, IL-4, IL-10, IL-17 before and after treatment in the serum by ELISA. Results The PASI scores of two groups were both significantly decreased after treatment (blood heat syndrome group t=6.685, P<0.01;blood stasis syndrome group t=4.959, P<0.01). The levels of cytokines were significantly different between patients in the periods of activity and quiescence. Onvarying degrees, the levels of cytokines of two groups were improved after treatment. The levels of cytokines IFN-?, IL-17 in blood heat group significantly decreased(t=3.024, P<0.01;t=2.543, P<0.05). The levels of cytokines IL-17 drop but the levels of cytokines IL-4 raised in blood stasis group,that were significantly differentwith the levels before treatment(t=2.417, P<0.05; t=2.547, P<0.05). Conclusion The levels of INF-?, IL-4, IL-10 and IL-17 could be effectively modulated with blood-stage treatment in treating psoriasis vulgaris.
