Through using the methods of finite-size effect and short time dynamic scaling,we study the criticalbehavior of parasitic disease spreading process in a diffusive population mediated by a static vector *** analysis of parasitic disease spreading we find that this model presents a dynamical phase transition fromdisease-free state to endemic state with a finite population *** determine the critical population density,abovewhich the system reaches an epidemic spreading stationary *** also perform a scaling analysis to determine theorder parameter and critical relaxation *** results show that the model does not belong to the usual directedpercolation universality class and is compatible with the class of directed percolation with diffusive and conserved fields.

AIM： To assess the outcomes of posterior chamber implantable collamer lens （ICL） implantation in Chinese pediatric patients with unilateral high myopic ***： Eleven eyes of 11 amblyopic patients aged 11.02±3.34y underwent ICL （model V4, Staar Surgical Inc.） implantation to treat unilateral anisometropia were studied. Visual acuity, cycloplegic refraction, contrast sensitivity, stereopsis, intraocular pressure （IOP）, vaulting, corneal endothelial cell count and complications were evaluated. Patients completed follow-up at 3d, 1, 3mo and the last follow-up time （mean 8.18±2.82mo） after ***： The mean myopic anisometropia was -13.70±3.25 D preoperatively and ＋0.69±2.63 D at 8mo postoperatively. The logMAR corrected distance visual acuity （CDVA） of the amblyopic eye was 1.51±0.72 preoperatively and 0.75±0.40 at 8mo postoperatively. The logMAR CDVA at 3d, 1, 3 and 8mo postoperatively improved by a mean of 0.64, 1.55, 1.82 and 2.64 lines and gained more than 2 lines accounted for 18%, 45%, 45%, 64%, respectively. The contrast sensitivity of 0.5, 1 and 2 cpd in amblyopic eyes was significantly increased after surgery. No patient had near stereopsis recovery. The vaulting at 3 and 8mo was significantly lower than that at 1mo postoperatively. No other intraoperative or postoperative complications were observed, except an acute pupillary block glaucoma happened in a patient at two weeks ***： This short-term results indicate that ICL implantation can be a promising alternative therapy for high myopic anisometropic amblyopia in pediatric patients who have failed with conventional treatments and not suitable to corneal refraction surgery.

本文考察了活性炭脱色法和树脂脱色法对三七多糖(Panax notoginseng polysaccharide,PNP)的脱色效果、物理性质及其体外抗氧化活性的影响。以综合评分为评价指标,通过单因素实验考察活性炭用量、温度、时间,在单因素实验基础上采用正交实验优化脱色条件;通过静态吸附实验,从6种树脂中筛选最佳脱色树脂,随后通过单因素实验考察其上样量、脱色时间、转速对综合评分的影响,在单因素实验基础上采用正交实验优化脱色条件。通过溶解度、粒径、差示扫描量热分析、傅立叶变换红外光谱分析、pH值、相对分子质量及其大小分析比较未脱色的三七多糖(Unbleached Panax notoginseng polysaccharide,UPNP)、活性炭脱色法制备的PNP(Panax notoginseng polysaccharide prepared by activated carbon decolorization,PNPC)及D285树脂脱色法制备的PNP(Panax notoginseng polysaccharide prepared by D285 resin decolorization,PNPD)的物理性质;并比较三者对DPPH、ABTS^(+)自由基清除率、金属离子螯合能力。结果表明活性炭脱色的综合评分为78.00%;D285为最佳脱色树脂,综合评分为71.00%。与UPNP、PNPC相比较,PNPD溶解度低,在水溶液中粒径分布不均匀、稳定性较差,pH值增大、相对分子质量较大,体外抗氧化活性低。推测由于D285树脂离子交换过程中产生的强碱性环境,导致PNP糖苷键水解所致。不同脱色方法会对PNP物理性质、体外抗氧化活性产生影响。

AIM: To investigate stepwise sedation for elderly patients with mild/moderate chronic obstructive pulmonary disease (COPD) during upper gastrointestinal (GI) endoscopy. METHODS: Eighty-six elderly patients with mild/moderate COPD and 82 elderly patients without COPD scheduled for upper GI endoscopy were randomly assigned to receive one of the following two sedation methods: stepwise sedation involving three-stage administration of propofol combined with midazolam [COPD with stepwise sedation (group Cs), and nonCOPD with stepwise sedation (group Ns)] or continuous sedation involving continuous administration of propofol combined with midazolam [COPD with continuous sedation (group Cc), and non-COPD with continuous sedation (group Nc)]. Saturation of peripheral oxygen (SpO 2 ), blood pressure, and pulse rate were monitored, and patient discomfort, adverse events, drugs dosage, and recovery time were recorded. RESULTS: All endoscopies were completed successfully. The occurrences of hypoxemia in groups Cs, Cc, Ns, and Nc were 4 (9.3%), 12 (27.9%), 3 (7.3%), and 5 (12.2%), respectively. The occurrence of hypoxemia in group Cs was significantly lower than that in group Cc (P < 0.05). The average decreases in value of SpO 2 , systolic blood pressure, and diastolic blood pressure in group Cs were significantly lower than those in group Cc. Additionally, propofol dosage and overall rate of adverse events in group Cs were lower than those in group Cc. Finally, the recovery time in group Cs was significantly shorter than that in group Cc, and that in group Ns was significantly shorter than that in group Nc (P < 0.001). CONCLUSION: The stepwise sedation method is effective and safer than the continuous sedation method for elderly patients with mild/moderate COPD during upper GI endoscopy.
