Objective To approach the clinical characteristics of extrapulmonary complication induced by mycoplasma pneumoniae(MP) infection and infectious mononucleosis syndrome. Methods The MP-IgM(+), EBV- IgM(+) were determined by enzyme- linked immunosorbent assay.There were 18 cases infected with MP and infectous mononucleosis syndrome with abnormal fever,cervix lyphadenectasis,pharyngitis,liver and spleen intumescence,lung infection, and so on.They were analyzed by reviewing.Results There were 8 cases(44.4%) with extrapulmonary complication, among them 3 cases(16.6%) with liver injury,1 case (5.56%) with heart injury,2 cases(11.1%) with both heart and liver injuries,1 case(5.56%) with urinary system injury (nephritis), 1 case (5.56%) with nervous system injury (encephalitis).The complication usually arised 1 week after primary affection, but had no typical clinical symptoms.There was only 1 case with encephalitis who expressed the symptom of nervous system symptom firstly, and was clinically dia- gnosed by assistant examinations. All the cases recovered after 3 weeks′ treatment with macrolides, 5-7 days with ganciclovir, and also with regular complication and support treatments.Conclusions The incidence of extrapulmonary complication induced by MP infection and infectous mononucleosis syndrome is higher than that by the single infection, and its clinical symptom isn′t obvious and is easy to be covered by original illness. And a few showing the extrapulmonary as the first symptom is easily mistakenly diagnosed .As a result, the prognosis is favorable if we make subsidiary inspection and diagnosis as soon as possible and give it with regular treatment.

To investigate the neuroprotective of ligustilide (LIG) against glutamate-induced apoptosis of PC12 cells, cell viability were examined by MTT assay. Flow cytometry was applied to assay cell apoptosis rate. Intracellular calcium concentration was measured by using fluorescent dye Fluo-3/AM. Cytochrome C (Cyt C), Caspase-3, Bax and Bcl-2 protein expression were assayed by western blot. The results showed that glutamate is cytotoxic with an inhibitory concentration 50 (ID50) of 15 mmol · L(-1). Pretreatment with LIG (1, 5, 15 μmol · L(-1)) significantly improved cell viability. The apoptosis rate in glutamate-induced PC12 cells was 13.39%, and decreased in the presence of LIG (1, 5, 15 μmol · L(-1)) by 9.06%, 6.48%, 3.82%, separately. Extracellular accumulation of Ca2+ induced by glutamate were significantly reduced by LIG. The results of western blot manifested that pretreatment LIG could decrease the release of Cyt C from mitochondria, down-regulate Caspase-3 protein expression and up-regulate Bcl-2/Bax ratio, thereby protects PC12 cells from apoptosis. In summary, LIG had protective effect on glutamate-induced apoptosis in PC12 cells through attenuating the increase in intracellular Ca2+ concentration, and inhibiting the release of Cyt C from mitochondria to cytoplasm.

Objective To detect the effect of osthole on proliferation and apoptosis of HL-60 cells and its molecular mechanism.Methods HL-60 cells proliferation was measured through the CCK8 assay method.The cell morphological changes were observed by Hoechst33342 staining after 8 h of drug effect.Induction of apoptosis was determined by flow cytometry and fluorescent microscopy.Expressions of Bcl-2 and Bax mRNA were evaluated by RT-PCR,and the expressions of cleaved caspase-3,caspase-8,caspase-9,Fas and FasL were evaluated by using western bolt assay.Results Osthole could inhibit the proliferation of HL-60 cells,the maximum inhibiting rate was (90.7 ±4.5)％,F =138.46,P =0.000; the apoptosis rate was 33.6％,F =27.75,P =0.006.The changes of apoptosis of cells and nucleus were shown in cell morphological observation.Osthole affected the decrease of the mRNA levels of Bcl-2 and the increase of the Bax mRNA levels via a dosedependent manner(F =210.12,P =0.000).Western blotting demonstrated that osthole could lead to the increase of the expression levels of cleaved caspase-3,caspase-8,caspase-9,Fas and FasL in the HL-60 cell line via a time-dependent manner.Conclusion Data suggests that osthole inhibits proliferation and induces apoptosis of HL-60 cells through mitochondria-dependent pathway and death-receptor pathway.

Objective To investigate the clinical characteristic and the predicting value of plasma Apelin in elderly patients with sepsis.Methods A retrospective analysis was conducted in 26 sepsis patients aged (72.9±9.7) years in average and 30 healthy controls.Serum Apelin level was measured by ELISA.Body mass index (BMI) and C-reaction protein (CRP) were detected.Patients were divided into survival group (n=18) and death group (n 8).According to acute physiology and chronic health evaluation (APACHE) Ⅱ,patients were divided into subgroup A (n=14,APACHE Ⅱ score≤20) and subgroup B (n=12,APACHE Ⅱ score＞20).Results The Apelin concentration was higher in sepsis patients than in healthy controls [(0.38±0.15)ng/L vs.(0.19±0.12)ng/L,t=2.011,P＜0.05].The Apelin concentration was lower in survival group than in death group[(0.21 ± 0.29)ng/L vs.(0.49 ± 0.32) ng/L,t =2.094,P＜0.05].The Apelin level was increased with APACHE Ⅱ scores increment in sepsis patients (P＜0.05).Multivariable logistic analysis showed that when taking survival/death as the dependent variable and Apelin as the independent variable,the ()R value was 4.162 with 95％ CI:1.115-15.535(P＜0.05).Conclusions Increased serum Apelin level reflects the severity of illness in patients with sepsis,which is a risk factor for death in prognosis of sepsis.

This study taking gestodene (GEST) as a model, investigated the factors affecting reservoir-type intravaginal ring (IVR)'s drug release. This paper reported a gestodene intravaginal ring of reservoir design, comprising a gestodene silicone elastomer core encased in a non-medicated silicone sheath, separately manufactured by reaction injection moulding at 80 degrees C and heating vulcanization at 130 degrees C is reported. The test investigated the factors affecting drug release through a single variable method, taking the drug release rates of 21 days as standards. When changing the thickness of the controlling sheath outside, the ratio of the first day of drug release and mean daily release (MDR), named the relatively burst effect, is closing to 1 with the thickness of controlling sheath increasing, while the 1.25 mm sheath corresponding to 1.04 controlled the burst release effectively; a positive correlation (r = 0.992 2) existed between the average drug release (Q/t) and drug loading (A) within a certain range. The C6-165 controlling sheath with high solubility of GEST is easier to achieve controlled release of the drug; GEST crystalline power is more effective to implement controlled release of drugs among difficent states of the drug. A 1/4 fractional segment core gives a relatively burst effect of 1.76, while the 1/1 and 1/2 are 1.93 and 1.87 separately, at the same drug loading, concluding that use of a fractional segment core would allow development of a suitable GEST reservoir IVR. In summary, GEST reservoir-type IVR could be adjusted by the thickness of controlling sheath, the loading of drug, the material properties of controlling sheath, the dispersion state of drug, the additive composition and structure of intravaginal ring, to control the drug release behavior and achieve the desired drug release rate.
