Objective To research the efficacy of alprostadil injection combined the octreotide for acute severe pancreatitis and influence on the serum levels of tumor necrosis factor-α(TNF-α),interleukin-6,interleukin-18,occludin.Method 68 cases of patients with acute severe pancreatitis from September 2013 to February 2017 in our hospital,according to the treatment method group,34 cases in each group,control group treatmented by octreotide,the research group based on the control group treatmented by alprostadil injection,both groups was treated for five days.Clinical curative effect,alleviate clinical symptoms time,TNF-α,IL-6,IL-18,occludin,and adverse reactions occur was compared between two groups.Results The total effective rate of research group was higher than the control group(97.07％vs.79.41％,P<0.05).Bowel sounds,stomach ache,body temperature and serum amylase remission time of research group was shorter than control group(P<0.05).TNF-α,IL-6,IL-18 of research group was lower than the control group(P<0.05),the occludin of research group was higher than the control group(P<0.05).The adverse reactions was no differences between the two groups.Conclusion The exact effect of alprostadil injection combined the octreotide for acute severe pancreatitis,improve serum levels of TNF-α,IL-6,IL-18,occludin.

The rats were exposed to 20Gy of X-ray one time systemically to imitate the model of AIRS. By using immunocytochemistry, immunoelectromicroscopy and microspectrophotometry (MSP) technique , the changes of rat thyroid gland C cells in AIRS were investigated. The results show that, the changes of C cells could be divided into two phases. In the first phase (the first 24 h after irradiation) , no obvious morphological change could be observed, whereas the concentration of serum calcium (CSC) dropped remarkably. It seems that the synthesis and secretion of calcilonin (CT) within C cells might increase during this period. The second phase is from 24th h to 72th h after irradiation, the TA (total absorbance) measured by MSP reduced. and the ultrastructural pictures showed progressive destructive changes. All these findings suggest that: The C cells of rat thyroid gland, as a kind of APUD system cell, is no doubt involved in the AIRS pathological changes. The possible pathogenic mechanism was briefly discussed.

Objective To study the characteristic of etiology and drug resistance of neonatal sepsis for rational use antibiotics in clinic.Methods The etiology and drug resistance of 167 positive hemoculture examples of 365 neonatal sepsis examples were retrospectively analyzed,and the characteristic of etiology diversify and drug resist-ance characteristic of neonatal sepsis were also analyzed.Results In 365 blood culture examples of neonatal sepsis, there were 167 positive cases,positive ratio was 45.75%.Among pathogenic bacterium,the first etiology was staphylo-coccus epidermidis,there were fifty -eight examples and account of 34.73%.The second was staphylococcus haemo-lyticus and accounts twenty -nine examples and 17.37%.The third was staphylococcus aureus which had twenty -two examples and account 13.17%.The annual infection rate of staphylococcus epidermidis and staphylococcus hae-molyticus in the second five years were increased obviously.Gram -positive coccus drug resistance to penicillin,cep-hazolin,oxazocilline and cefoxitin were very high and the rate of the second five years were higher than that of the first five years.Gram -positive coccus drug resistance to third -generation cephaloporins and imipenem and meropenem were higher than vancocin and the rate of the second five years were higher than that of the first five years.Gram -positive coccus was 100.00% sensitive to vancomycin.Gram negative bacilli drug resistance rate to penbritin and cep-hazolin and third -generation cephaloporins was the highest.Gram negative bacilli to meropenem and imipenem was hypersensitive in all antibiotics.Conclusion The chief pathogenic bacteria of neonatal septicemia is staphylococci. Among pathogenic bacterium,the main pathogenic bacteria is CoNS,and staphylococcus epidermidis and staphylococ-cus haemolyticus goes up significantly.Among gram -negative bacilli,the escherichia coli goes up.The drug resist-ance to bacteria goes up in neonatal sepsis,it is very important to monitor the drug resistance.

HPV in remission CA,so the disease can be cured.

Hypoxia-inducible factor-1 (HIF-1), as a nuclear transcription regulator of the hypoxic response, is up-regulated during hypoxia, and it regulates a series of downstream target gene expression, such as vascular endothelial growth factor, glucose transporter and erythropoietin through binding with hypoxia response element. It plays important roles in angiogenesis, anerobic metabolism, cell survival, proliferation, migration, and differentiation.This article reviews the structure, function and activity regulation of HIF-1 and its roles in acute ischemic brain injury.

OBJECTIVE: To establish RP-HPLC method for the content determination of chlorogenic acid in 3 kinds of dosage forms of Qingkailing preparation. METHODS: SinoChrom ODS-AP C18(250 mm?4.6 mm, 5 ?m) column was adopted and the mobile phase consisted of methnol-water-acetic acid (25 ∶ 75 ∶ 0.5) at the flow rate of 1.0 mL?min-1. Column temperature was set at 30 ℃ and the detection wavelength was set at 327 nm. RESULTS: The linear range of chlorogenic acid was 3.81～152.50 ?g?mL-1(r=0.999 8), and the average recoveries of the capsules, granules and dripping pills were 99.03%(RSD=2.02%), 99.35%(RSD=1.16%),98.11%(RSD=1.51%). CONCLUSION: The method is sensitive, simple and accurate for the quality control and content determination of 3 kinds of Qingkailing preparations.

Objective:To investigate the safety and efficacy of interleukin-6 antisense oligonucleotide liposomes on the experimental animals for prevention of after cataract. Methods:Thirty healthy New-Zealand rabbits(30 left eyes) received extracapsular lens extraction,and were randomly divided into 3 groups: anterior chamber injection of 0.1ml of interleukin-6 antisense oligonucleotide liposomes(Group A),blank liposomes(Group B) after operation respectively;and control group(Group C).All left eyes were examined by slit-lamp microscope and ophthalmoscope regularly.The aqueous humor IL-6 concentrations were measured 1 day before operation,and 1 day,3 days,7 days,14 days and 30 days after operation through enzyme-linked immunoabsorbent assay.Three months later,photographs of the posterior lens capsules were taken through digital slit-lamp microscope and the histopathological changes of posterior lens capsules were observed by light microscope. Results:①Three months after the operation,the number of eyes developing posterior capsule opacification in Group A,B and C were 7,10 and 10 respectively,with significant difference(P=0.037).② The average value of Group A was lower than Group B and C,with statistically significant difference(P

Much attention has been paid to photocatalytic oxidation in the field of air and water purification. Photocatalytic oxidation employs semiconductors such as TiO2, ZnO as a photocatalyst in ultraviolet radiation. Several factors which affect photocatalytic decomposition were discussed in the present paper. Photocatalytic oxidation technique is applicable for the elimination of gas-phase contamination in air.

As a novel testing method in clinic,the technology of genetic testing and its application appear prosperous in many areas,such as genetic diagnosis,therapy,prevention and biological pharmacy,etc.With the application of the genetic testing,some related ethical,legal and social problems also emerged.A preliminary study is conducted on the potential ethical problems that appear in genetic testing,such as individual mental burden,family relationship,public pressures,etc.Relevant ethical principles are also put forward,especially the admission criteria of genetic testing to provide a reference for the application and management of genetic testing in our country.
