Activin receptor-like kinase (ALK) 1 is a transforming growth factor-β/bone morphogenetic pro-teins superfamily type Ⅰ receptor, predominantly expressed in active endothelial cells. ALK1 has been shown to play a piv-otal role in regulating angiogenesis, which is involved in vascular formation during embryonic and early postnatal develop-ment and angiogenesis-related diseases, such as cardiovascular disorders and tumor. Understanding the exact function of ALK1 in angiogenesis will provide theoretical basis for anti-angiogenic strategy of ALK1 inhibition. In the present study, we briefly recapitulate ALK1 signaling pathway and its role in blood vessel formation and pathological neovascularization.

BACKGROUND:Hand-foot-mouth disease has become a major public health issue in children in China. In the present prospective study we investigated the clinical characteristics and emergency management of children with severe encephalitis associated with NPE caused by enterovirus 71. METHODS:The study was conducted in 2 pediatric intensive care units (PICUs) over a 2-month period. Clinical records were reviewed of critically ill children with severe encephalitis associated with NPE caused by EV71 who were admitted to PICUs during the period of May to June 2008 in Fuyang. RESULTS:We reviewed the complete records of 36 children, of whom 23 (63.9%) were male and 13 (36.1%) female. Their age ranged from 4 to 48 months, with an average of 15.8 months. Al children except one were under 3 years of age. The overal mortality in these children was 19.4%. The average duration of critical life threatening signs and symptoms was 2.1 days (12 hours-5 days). Nervous system diseases included brainstem encephalitis in 27 children (75%), brainstem encephalitis associated with myelitis in 6 children (16.7%), and general encephalitis in 3 chidren (8.3%), respectively. In 12 patients of NPE (33.3%) pink or bloody bubble sputum and asymmetric pulmonary edema or hemorrhage was the primary manifestation but no typical exanthema was observed. Five children died of acute onset of NPE and / or pulmonary hemorrhage with rapid progression of cardiopulmonary failure within hours after admission. Therapeutic management consisted of mechanical ventilation and administration of mannitol, methylprednisolone, intravenous immunoglobulin (IVIG) and vasoactive drugs, associated with the need of fluid volume resuscitation in 9 (25%) of the 36 children. CONCLUSIONS:In children less than 3 years of age found to be affected by severe EV71 encephalitis associated with NPE, one fifth may die. The major organ systems infected by severe EV71 include the central nervous system, the respiratory system, and the cardiovascular system. Early diagnosis and evaluation, respiratory support, treatment of intracranial hypertension, and mainttenance of function of the cardiovascular system are the most important therapeutic measures.

OBJECTIVETo investigate the effects of lipopolysaccharide (LPS) on airway inflammation, airway remodeling and the expression of Toll-like receptor 4 (TLR4) mRNA in asthmatic rats.
METHODSTwenty-four SPF level SD rats were randomly divided into four groups (n = 6): control group, low dose of LPS group, high dose of LPS group and asthma group. Using ovalbumin (OVA) to sensitize and challenge to establish asthmatic rat model. Observed pathological changes of lung tissue by HE staining, inflammatory cell infiltration was observed by airway wall eosinophils (EOS) counts; airway resistance was determined; image analysis software was used to determine the thickness of airway wall, detected airway smooth muscle TLR4 expression levels by RT-PCR.
RESULTSThe rat airway resistance and the EOS number of airway wall and the thickness of airway wall in asthma group, low dose of LPS group and high dose of LPS group were significantly higher than those in control group (P < 0.01). The above-mentioned parameters of high dose of LPS group showed significantly lower than those in asthma group and low dose of LPS group (P < 0.05). The expression of rat airway smooth muscle TLR4 mRNA in low dose of LPS group and high dose of LPS group were significantly higher than those in asthma group (P < 0.01). And the expression of rat airway smooth muscle TLR4 mRNA in high dose of LPS group was significantly higher than that in low dose of LPS group (P < 0.05).
CONCLUSIONTLR4 plays an important role in asthmatic airway inflammation and airway remodeling, LPS may play double-sided regulation in asthmatic airway inflammation and airway remodeling by activated TLR4.

OBJECTIVETo explore the molecular mechanism of dutasteride inhibiting fertility by studying its effects on the expressions of the epididymal epithelial junction proteins Claudin1 and β-catenin in rats.
METHODSSixteen 3-month-old SD male rats were equally divided into an experimental and a negative control group to be treated intragastrically with dutasteride at 40 mg/kg per day and the same dose of solvent, respectively, for 14 consecutive days. Then, the sperm motility and morphology of the rats were detected by computer-assisted sperm analysis, the serum levels of testosterone (T) and dihydrotestosterone (DHT) measured by ELISA, changes in the tight junction of epididymal cells observed under the transmission electron microscope, the protein and gene expressions of Claudin1 and β-catenin determined by RT-PCR and immunohistochemistry, and the conception rate of the mated female rats calculated.
RESULTSDutasteride significantly suppressed the serum DHT level, sperm motility, and fertility of the rats (P <0.05). Interspaces between epididymal epithelial cell tight junctions were observed, the volume of epididymal fluid obviously increased, and the expressions of Claudin1 and β-catenin gene and protein remarkably downregulated in the experimental rats (P <0.05).
CONCLUSIONDutasteride can significantly inhibit the fertility of male rats by reducing the serum DHT level, suppressing Claudin1 and β-catenin expressions, and damaging epididymal epithelial cell junctions.

OBJECTIVETo verify the efficacy of Jianpi-xingniao needling therapy on prevention and treatment of motion sickness.
METHODSSixty volunteers of motion sickness were randomized into an acupuncture group and a delayed acupuncture group, 30 cases in each one. In the acupuncture group, acupuncture was given at Baihui (GV 20), Sishencong (EX-HN 1), Neiguan (PC 6), Zusanli (ST 36) and Hegu (LI 4). The needles were retained for 20 min. The treatment was given twice a week and 10 treatments were required. In the delayed acupuncture group, acupuncture was postponed, meaning no acupuncture during observation stage. Graybel scale was adopted to observe the score of symptoms and physical signs of the subjects of motion sickness before and after intervention. The efficacy was compared between the two groups.
RESULTSTwenty-five cases in the acupuncture group and 22 cases in the delayed acupuncture group were included in the statistical analysis. The score of symptoms and physical signs of motion sickness was reduced significantly after treatment in the acupuncture group as compared with that before treatment (10.12 +/- 3.37 vs 0.92 +/- 0.40, P < 0.05). The score in the acupuncture group was lower apparently than that in the delayed acupuncture group (0.92 +/- 0.40 vs 9.86 +/- 2.53, P < 0.05). The difference was not significant before and after treatment in the self-comparison of the delayed acupuncture group (P > 0.05). The total effective rate was 96.0% (24/25) in the acupuncture group, which was significantly better than 0.0% (0/22) in the delayed acupuncture group (P < 0.01).
CONCLUSIONJianpixingniao needling therapy relieves the symptoms of motion sickness in the patients and achieves a better clinical efficacy.

In the present study, the genome shuffling was used to improve lipase production of Penicillium expansum. A lipase producing mutant strain-Penicillium expansum FS8486 and a wild type of Aspergillus Tamarii FS-132 isolated from soil of a volcano in Xinjiang were used as the parental strains. After two rounds of genome shuffling, several elite daughter strains were screened. The lipase activity in one of the daughter strains was increased 317% over the starting strain FS8486. Comparisons of the morphology, RAPD (Random Amplification of Polymorphic DNA) polymorphism and the fatty acid compositions between the daughter and the parental strains suggested that the filial generation were generated by genome shuffling. In this study, the genome shuffling used successfully first time in eukaryotic microorganism and increases the production of the desired metabolite in short time, the study will be useful to spread the genome shuffling in eukaryotic microbial breeding.
