Objective To understand the acute effect of ambient air CO pollution on daily mortality of cerebrocardiovascular diseases among highly and long-term exposed residents of 65 years and over in Taiyuan,Shanxi,China.Methods The relationship of CO concentration and daily mortality of cerebrocardiovascular diseases among residents over 65 years old in Taiyuan(2003-2004) was analyzed by case-crossover design and conditional Logistic regression in SAS 9.0 Results The 48 h accumulated CO concentration had the most significant effect.As increment of CO average was 100 ?g/m~3,the corresponding OR of the effect on the total deaths of the cerebrocardiovascular diseases,the cardiac disease,the ischemic heart disease,myocardial infarction,cardiac failure,arrhythmia and stroke was 1.006,1.010,1.007,1.005,1.005,1.006 and 1.012 respectively.Under different air pollution conditions,the pollutant presented different effects on deaths of eerebrocardiovascular diseases.Conclusion The current CO pollution has caused a certain adverse effect on the cerebrocardiovascular mortality among residents of 65 years and over in Taiyuan city.More stringent measures should be taken to control the air pollution and decrease CO level,thus reduce the mortality of cerebrocardiovascular diseases.

Objective:To investigate the pharmacokinetics of mycophenolic acid( MPA)and its metabolites in different stages af-ter the administration of enteric-coated mycophenolate sodium( EC-MPS)tablets in Chinese liver transplant recipients. Methods:The blood samples of 24 patients were collected in 0-12h of the 1st and 3rd week after the administration of EC-MPS. The concentrations of MPA,AcMPAG and MPAG in plasma were measured by LC-MS/MS developed in our lab. The pharmacokinetic parameters of MPA and its metabolites were estimated by non-compartmental method. Results:After 1-and 3-week therapy with EC-MPS,Cmax ,AUC0-12 and t1/2 was(18. 1 ± 8. 75)and(20. 7 ± 16. 0)μg ml-1 ,(42. 7 ± 17. 5)and(47. 1 ± 23. 9)μg·h·ml-1 ,(3. 33 ± 2. 81)and (3.30 ±1.89)h for MPA;(2.50 ±1.86)and(1.78 ±1.72)μg·ml-1,(14.5 ±11.7)and(6.97 ±6.57)μg·h·ml-1, (4. 48 ± 2. 53)and(3. 76 ± 1. 8)h for AcMPAG;(171. 6 ± 135. 4)and(152. 2 ± 115. 9)μg·ml-1 ,(1299 ± 1 204)and(1 051 ± 561)μg·h·ml-1 ,(8. 73 ± 4. 25)and(7. 75 ± 2. 87)h for MPAG,respectively. There was no significant difference in the PK parameters of MPA after the 1-and 3-week therapy. The Cmax ,Tmax and t1/2 of MPA in the patients received EC-MPS were significantly higher than those in the patients received MMF(P<0. 05). Cmax and AUC0-12 of MPAG in the patients received EC-MPS were signifi-cantly higher than those in the patients received MMF after the 3-week therapy(P<0. 05). Conclusion:There is no significant accu-mulation of MPA after the therapy with EC-MPS at different stages. The absorption of MPA is delayed after the therapy with EC-MPS compared with that with MMF. There is no difference in MPA exposure between EC-MPS and MMF in Chinese liver transplant patients.

With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.

Lipids of Thamnidium elegans,Mortierella ramanninace,Rhizopus arrhizus,Pythium irregulare and Rhodotorulla aurantiaca were extracted by Soxhlet extraction,supercritical-CO 2 fluid extraction,acid-heating extraction and organic solvent extraction,respectively.Four extraction methods were evaluated on sample treatment,minimum sample quantity,requirements of apparatus,ability of treating sample and content of lipid.The components of fatty acids were analysed by gas chromatography.Soxhlet extraction can acquired maximum lipid content,but it took the most time.Supercritical-CO 2 fluid extraction and acid-heating extraction has a same lipid content which was lower than that of Soxhlet extraction.Acid-heating extraction was the most handy,and its ability to treat sample in a hour was the most powerful.Organic solvent extraction was less efficient.Acid-heating extraction was a simple and efficient method of fungi lipid extraction fitting to breed mutant strains that highly producting lipid and polyunsaturated fatty acids.

The effects of somatic and visceral nociceptive stimulation on neurons of dorsal commissural nucleus in sacral spinal cord were studied in pentobarbitone anesthetized cats using extracellular recording techniques. The results indicated that all neurons deriving input from Aδ fibers of the pelvic nerve were either nociceptive specific or wide dynamic range neurons, and could be activated by mechanical or intense electrical stimulation of the respective receptive fields including perianal region. The above results suggest that the Aδ afferents innervation of the pelvic organ is important in nociception.

Antimicrobial peptides, a cluster of small peptides secreted by the majority of creatures, have been demonstrated with activity against a wide range of microorganisms including bacteria, protozoa, yeast, fungi, viruses and even tumor cells. These peptides have some features such as broad spectrum , high effi-cacy and stability, little drug resistance. A lack of new antibiotics combined with emerging multi-drug resis-tance issues demands that new antimicrobial strategies be explored for treating these infections. It has been proposed that the antimicrobial peptides might form the foundation for a new class of clinically useful an-timicrobials. We review the advantages of these molecules in construction features and bioactivity, with the focus on the mechanism and clinical applications.

Objective To analyze the effect of probiotics combined with early enteral nutrition on infection and gastrointestinal dysfunction in patients undergoing mechanical ventilation in intensive care unit (ICU).Methods Prospective cohort study was adopted to select patients who admitted to ICU in a hospital from February 2016 to October 2017, they were randomly divided into three groups:A, B, and C.Group A received early enteral nutrition combined with probiotics, group B received early enteral nutrition, and group C received early parenteral nutrition.Infection condition, level of infection indicators (on the 3 rd, 7 th and 14 th day after treatment), occurrence of gastrointestinal dysfunction, acute physiology and chronic health evaluation II (APACHE II) on the 14 th day after treatment were compared among three groups.Results Incidences of infection in group A, B, and C were 6.00％, 20.00％, and 22.00％ respectively, difference among three groups was significant (χ2=8.57, P=0.01).C-reactive protein (CRP) and white blood cell count (WBC) in group A on the 7 th and 14 th day were both lower than those in group B and C;procalcitonin (PCT) in group A and B on the 3 rd day were both lower than that in group C;PCT in group A on the 7 th and 14 th day were both lower than those in group B and C;difference were all statistically significant (all P＜ 0.05).Incidence of abdominal distension (8.00％), diarrhea (4.00％) and gastric retention (4.00％) in group A were the lowest among three groups.APACHE II score in group A on the 14 th day after treatment was lowest.Conclusion Early enteral nutrition combined with probiotics for treatment of ICU patients with mechanical ventilation can effectively reduce the incidence of infection and gastrointestinal dysfunction, promote rehabilitation, which is worth promoting the application.
