Objective To study the influence of blood glucose, blood lipids and other cerebral infarction risk factors in the mean platelet volume (MPV). Methods A total of 562 patients with cerebral infarction and type 2 diabetes mellitus (DM) and 216 cerebral infarction patients without DM (non-DM) were included in this study. The platelet parameter of peripheral blood and other laboratory indexes were detected including platelet count (PLT), MPV, platelet distribution width (PDW), plateletcrit (PCT), fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL-C), low density lipoprotein (LDL-C) and very low density lipoprotein (VLDL-C), urea nitrogen (BUN), creatinine (Cr), uric acid (UA), high-sensitivity C-reactive protein (hs-CRP) and homocysteine (HCY). The patients were scored by the National Institute of Health stroke scale (NIHSS) after hospitalization. The MPV changes in patients with cerebral infarction were observed, and different influences of blood glucose, blood lipids to MPV were analysed. Results Values of FBG, HbA1c, TC, TG, LDL-C, BUN, UA, HCY, hs-CRP, and NIHSS were significantly higher in DM group than those of non-DM group. The score of NIHSS was significantly higher in DM group than that of non-DM group. The level of HDL-C was significantly lower in DM group than that of non-DM grou. The MPV was significantly higher in DM group than that of non-DM group [(9.60 ± 1.35) fL vs. (9.27 ± 1.01) fL, P<0.05). There was a positive correlation between MPV and FBG, HbA1c, hs-CRP, WBC, VLDL-C and NIHSS, r=0.438, 0.410, 0.336, 0.164, 0.321 and 0.249 (P<0.05). Multiple regression analysis showed that FBG, VLDL-C, HbA1c, hs-CRP and NIHSS were the independent influential factors of MPV (P<0.05). Conclusion The influencing factors of MPV should be controlled in patients with cerebral infarction combined with type 2 diabetes mellitus, reducing the activation of platelet, and delaying the progress of cerebral infarction.

The clinical data of 3 cases of Ramsay-Hunt syndrome concurrent with ipsilateral vocal cord paralysis were retrospectively analyzed, and the relevant literatures were also reviewed. Ramsay-Hunt syndrome is a kind of disease characterized by heavy ear pain, herpes zoster oticus and inner ear neurologic symptoms, which can also affect the vocal cords and give rise to vocal cords paralysis. Ramsay-Hunt syndrome can cause multiple in flammation of cranial nerves. The viral infection can also involve the 3rd and 10th cranial nerves. It mainly damage the facial nerve, followed by the involvement of vestibulocochlear nerve. The vagus nerve damage is rare, so the relevant clinical reports are less. It is important to take the objective data as well as subjective symptoms of the patients into consideration to make a definite diagnosis, so that we can treat it as soon as possible to achieve better curative effect.

This paper is to report the development of a rapid and sensitive method for the determination of s-oleylpropanolamide (OPA) in various tissues of rat (brain, heart, lung, liver, spleen, small intestine, kidney, adipose tissue and muscle), and to assess the applicability of the assay to tissue distribution. OPA was extracted by liquid-liquid extraction method with undecylenoylethanolamide as an internal standard. The concentrations of OPA were determined by LC-MS/MS after a single intragastric dose of 50 mg x kg(-1) at 4 time points (5 rats per group). With multiple reactions monitoring mode (MRM) the limit of quantification (LLOQ) was determined at 1 microg x L(-1). The calibration curve was linear from 1 to 2 x 104 microg x L(-1) (r > or = 0.999 0) for tissue homogenates. Validation parameters such as accuracy, precision and recovery were found to be within the acceptance criteria of the assay validation guidelines. The highest concentration was found in small intestine (the highest time point is 15 min) and heart (the highest time point is 90 min). The assay is rapid, sensitive and applicable to studying tissue distribution of OPA in rats.

Objective To compare the blood-saving effect when acute hypervolemic hemodilution (AHH) was performed with hydroxyethyl starch (HES) 130/0.4 dissolved in electrolyte injection (HES-E) and HES 130/0.4 in sodium chloride injection (HES-NaCl).Methods Thirty patients of both sexes,aged 18-60 yr,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,with body mass index of 18-25 kg/m2,hemoglobin (Hb) ＞100 g/L,hematocrit (Hct) ＞ 35％,scheduled for elective abdominal operations under general anesthesia,were randomly divided into HES-E group and HES-NaCl group using a random number table,with 15 patients in each group.AHH was performed after induction of anesthesia.In HES-E and HES-NaCl groups,HES-E and HES-NaCl 15 ml/kg were intravenously infused over 30 min,respectively,and the infusion was conpleted before skin incision.Immediately after onset of AHH (T1),at 2 h after the end of AHH (T2),and at the end of operation (T3),arterial blood samples were collected for blood gas analysis and blood routine test,and pH value,base excess,HCO3-,K+,Na+,Cl-,Ca2+,Hb and Hct were recorded.Venous blood samples were collected at T1 and T2 for measurement of blood coagulation parameters including prothrombin time,activated partial thromboplastin time and fibrinogen and thrombelastography parameters.The volume of liquid intake and output and requirement for allogeneic blood transfusion were recorded,and the blood volume expansion rate was calculated.Results Compared with group HES-NaCl,no significant changes were found in the total volume of liquid infused,requirement for allogeneic blood transfusion,blood volume expansion rate,blood coagulation parameters at each time point,Hb and Hct (P＞0.05),pH value,base excess,HCO3 and K+ were significantly increased,and Na+ and Cl-were significantly decreased in group HES-E (P＜0.01).Conclusion There is no significant difference in the blood-saving effect between AHH with HES-E and HES-NaCl clinically,but HES-E can maintain homeostasis better.

Objective To study the correlation between alanie aminotransferase(ALT) unqualified samples and hepatitis B sur‐face antigen(HBsAg) and hepatitis C virus antibody (anti‐HCV) detection and to investigate an effective measure for reducing the discard rate of donated blood .Methods 330 633 blood samples donated by volunteers in Shenzhen Municipal Blood Center from January 1 ,2009 to December 31 ,2013 were performed the ALT ,HBsAg and anti‐HCV detection .Then the correlation between the detection results of ALT and viral hepatitis .Results Among 33 0633 donated blood samples ,there were 932 cases (0 .282% ) of ALT positive and 2 965 cases (0 .897% ) of viral hepatitis positive ,the differences were statistically significant (P<0 .05) .915 cases were unqualified in ALT ,but negative in viral hepatitis ,which accounting for 98 .176% of all ALT unqualified samples ;the blood discard rate generated by ALT disqualification was 0 .277% (915/330633) .Conclusion Our study indicates that the statistical difference exists in the ALT unqualified rate and the viral hepatitis detection rate ,conducting the ALT detection has the lower coin‐cidence rate for expected viral hepatic ,many false positive lead to the discard of normal blood .Therefore ,whether to continue using the ALT detection as the auxillary detection indicator is still being negotiated .

3-Hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) is the first rate-limiting enzyme for sesquiterpene synthesis in the mevalonate (MVA) pathway. The specific primers were designed according to the transcript sequence of AsHMGR2 from the Aquilaria sinensis (Lour.) Gilg transcriptome database. The full-length cDNA of AsHMGR2 was cloned by RT-PCR and rapid amplification of cDNA ends (RACE) technology, and was analyzed at bioinformatics levels; AsHMGR2 expression profiles in different tissues and in responds to different treatments were analyzed by real-time PCR. The length of AsHMGR2 Open Reading Frame (ORF) was 1 749 bp, encoding 582 amino acids. The GenBank accession number is KC140287. Tissue expression analysis indicated that AsHMGR2 was mainly expressed in root and shoot tips, followed by stem, and was lowest in leaves. Inducible-experiments showed that the genes were induced by mechanical wound as well as chemical liquid induction, and reached the highest expression level at 6 h and 8 h, separately. The full-length cDNA of AsHMGR2 and its expression patterns will provide a foundation for further research on its function in agarwood sesquiterpene biosynthesis.
