Sepsis is a life-threatening organ dysfunction caused by dysregulation of the host response due to infection, and it can further develop into septic shock.Currently, sepsis is still a leading cause of death in children all over the world.Therefore, early assessment of the severity and prognosis of sepsis is of great significance.However, there are no indexes with high sensitivity and specificity for evaluating the severity and prognosis of sepsis at present.In recent years, a large number of studies have revealed the essential role of platelets in sepsis.It has been reported that the platelet count is an independent factor affecting the severity and prognosis of sepsis patients.Up to now, the specific mechanism of sepsis-induced thrombocytopenia has not been fully clarified.In this review, the value of thrombocytopenia in predicting the severity and prognosis of sepsis patients was elaborated.

Objective To investigate the short-term effect of pelvic floor muscle training (PFM) with biofeedback on stress urinary incontinence (SUI) in postpartum and post-menopausal women.Methods According to the different period that the SUI occurs,107 women with SUI were divided into two groups:the group of SUI in postpartum with 60 women,and the group of SUI in post-menopausal with 47 women.PFM with biofeedback was performed on all patients for 8 weeks.One hour pad-weighing test,voiding diary,transperineal three-dimensional ultrasound and female pelvic floor muscle assessment were recorded before and after treatment.Results There was statistically significant difference in 1 hour padweighing test between pre-treatment and post-treatment for the group of SUI in postpartum (the negative,mild,moderate,and severe cases of post-treatment:21,24,14,1,of pre-treatment:0,30,28,2; P＜0.05),and the group of SUI in post-menopausal (the negative,mild,moderate,and severe cases of post-treatment:7,22,11,7,of pre-treatment:0,14,25,8; P＜0.05).The strength of the pelvic floor muscles of type Ⅰ and type Ⅱin two groups after treatment were significantly different from those in pre-treatment (P＜0.01).The efficient rate of improvement in symptoms after treatment in the group of SUI in postpartum was 88％ (53/60) and the cure rate was 38％ (23/60).While the efficient rate in the group of SUI in post-menopausal women was 64％(30/47) and the cure rate was 15％ (7/47).There was statistically significant difference in the development of symptoms in two groups after treatment (P=0.003).Conclusion PFM with biofeedback is an effective treatment for SUI in postpartum and post-menopausal women,especially for postpartum ones.

Ras/Raf/MEK/ERK singal transduction plays an important role in cell proliferation, differentiation, apoptosis, metastasis and metabolism. This investigation focused on this signal pathway and chose farnesyl transferase (FTase) as the main target and Raf-1 kinase as the second target. A lot of compounds were selected to construct the pharmacophore models of farnesyl transferase inhibitors (FTIs) and Raf-1 kinase inhibitors by using computer-aided drug design (CADD). The pharmacophore of FTIs is constituted by a hydrogen bonding acceptor, an aromatic ring, a positive ionizable and two hydrophobic regions; the pharmacophore of Raf-1 kinase is constituted by a hydrogen donor, a hydrogen acceptor, a hydrophobic regions and an aromatic ring. There are some similarities between the two pharmacophores. After analysis of the constructions of these two pharmacophores, some new aminomethylbenzoic acid derivatives with good forecasting activity against both of FTase and Raf-1 kinase were designed with these new pharmacophore models.

AIM: To observe if there is a synergistical effect on induction of apoptosis when arsenic trioxide alone or combination with bortezomib in KM3 cells. METHODS: KM3 cells were treated with arsenic trioxide alone or combined with bortezomib, the numbers of viable cells were determined by trypan blue exclusion. Cell growth inhibition was examined by MTT method. The cells were simultaneously stained with annexin V-FITC and PI and apoptosis was determined by bivariate flow cytometry using a FACScan. Reverse trascriptional-PCR (RT-PCR) method was used to examine the change of p65 mRNA and Western blotting to measure the expression of protein p65, p-p65, caspase-3, -8, -9, and poly ADP-ribose polymerase (PARP). RESULTS: Arsenic trioxide inhibited the cell growth and induced apoptosis. The mechanism was responsible for the activation of caspase-mediated induction of apoptosis. A synergistic effect of combination with bortezomib on apoptosis was observed. CONCLUSION: Arsenic trioxide inhibits KM3 cell growth and induces apoptosis with a synergistical effect when cotreated with bortezomib.

[Abstract ] Objective To understand the identification and in vitro antifungal susceptibility of Penicillium marneffei(PM)in yeast phase,and guide clinic antifungal application.Methods Strains isolated from blood and bone marrow of 23 patients infected with PM in a hospital between 2009 and 2016 were collected,colony morpholo-gy of PM in yeast phase was observed,susceptibility to itraconazole,voriconazole,amphotericin B,and fluconazole were detected with E-test method.Results Colony morphology of PM were as follows:direct microscopic examina-tion of Wright’s staining of tissue specimens found visible oval or round spore with apparent septum,and mainly lo-cated in macrophage;Gram staining of blood culture specimens found that strains were with bulbous and slightly curved ends,occasionally branched and with septum. PM was dimorphic fungi,presented mycelium at 28° C,pro-duced red pigment and diffused into medium;PM presented yeast form at 35° C,there were typical colony morpholo-gy. Minimum inhibitory concentrations (MICs)of itraconazole,voriconazole,amphotericin B,and fluconazole to PM in yeast phase were 0.002-0.016,0.012-0.125,0.002-0.500,and 0.500-16.000μg/mL respectively. Conclusion Typical colony morphology and fungal spore of PM in bone marrow and peripheral blood are important features for identification. PM is most susceptible to itraconazole,followed by voriconazole and amphotericin B, while fluconazole is less susceptible.

In order to investigate the genetic basis of morphological variation of tetraploid plantlets of Atractylodes macrocephala, diploid plantlets were taken as experimental material, sterile filtration colchicine was used to soak 0.5-1.0 cm long buds. The difference between morphology and stomatal of diploid and tetraploid of A. macrocephala was compared, and genome polymorphism was explored by AFLP. The results showed that the buds dipped in 0.1% colchicine solution for 36 h was optimal conditions to induce tetraploid of A. macrocephala with induction rate of 32.0%. Morphological indexes such as leaf area index, leaf length and width, the density of stomas and the number of chloroplast of tetraploid were distinctly different from diploid. Four hundred and fifty-one bands ranging with 80-500 bp were amplified with 24 pairs of primers, the rate of polymorphism was 32.59%. These amplification sites of diploid were different from tetraploid of A. macrocephala, and the differences in morphology of them were reflected in the DNA polymorphism.
