光相干断层扫描检测筛板结构的临床应用及新进展

筛板是位于视旁深部,由胶原纤维构成的筛束和穿行有神经、血管及神经胶质细胞的筛孔组成的复杂结构,为视网膜神经节细胞轴突穿出眼球时提供结构和营养支持。眼压引起机械应力的直接作用以及筛板变形和重塑导致轴浆运输、血运障碍,共同导致视网膜神经节细胞轴突损伤进而死亡。因此,筛板被认为是青光眼病变的始发部位。光相干断层扫描技术的发展...

基于“肺膀胱别通”浅析针刺肺经穴调治膀胱病

肺与膀胱相通,上为荣养周身以御邪,下以气化排浊调津液,从肺与膀胱关系可以看出,太阳之气与肺气共同卫外,以顾护肌表皮毛,故临床针刺治疗太阳体证时可考虑从肺经穴入手。临床取肺经穴位调治膀胱及其经脉病时,应辨别虚实,采取对应的补泻手法,考虑大部分肺经穴提插、捻转补泻手法不便施展,笔者认为可根据辨证采用更为合适的迎随补泻、徐疾补泻、开阖补泻,即观其脉证,补泻择之。其实不仅肺经穴可治膀胱病,膀胱经穴亦可治肺病,由于肺与膀胱两者经气互通,其中一条经上的穴位可治疗另一条相通经的循行部位或主治方向的疾病。虽然脏腑别通理论在针灸学上具备广泛应用的基础,但因表里经脏腑相互属络关系,更多被提及、应用的是"肺与大肠相关"。容易忽视"肺膀胱别通"在"卫气供给""津液代谢"上的关联。故在临床针刺治疗膀胱病时,可从有别于常规、传统的选经取穴上论治,亦可基于"肺与膀胱相关"以膀胱经穴治肺病,或以两经同取的方式指导针刺治疗相关病证。     

Ligation of the Left Atrial Appendage Using an Automatic Surgical Stapler

We investigated the use of an automatic surgical stapler for ligation of the atrial appendage in sheep, and then applied this technique in patients. Fourteen adult sheep underwent ligation of the left atrial appendage using a surgical stapler with a rotating head and either absorbable or stainless steel staples. In 4 sheep, killed after two hours, no hemorrhage or intraatrial thrombus was observed acutely. Ten sheep were allowed to recover for 90 to 100 days, twice the expected absorption time of absorbable staples. There was complete obliteration of the left atrial appendage without evidence of intraatrial thrombus or staple migration. The absorbable staples were completely reabsorbed. We subsequently used this technique in 5 patients undergoing mitral valve procedures. There were no complications, and adequate obliteration of the atrial appendage was achieved.     

Calcium carbonate modified urea–formaldehyde resin adhesive for strength enhanced medium density fiberboard production

This study investigated the improved properties of calcium carbonate (CaCO₃) modified urea–formaldehyde (UF) resin adhesive for medium density fiberboard (MDF) production. The CaCO₃ modified UF resins were prepared by adding different proportions of CaCO₃ to a low molar ratio UF resin at the initial stage of a typical synthetic process of the resin. The physicochemical properties of the resins were measured. The mechanical and environmental performances of the resin-bonded MDF panels were tested. The results show that the viscosity and free formaldehyde content of UF resins with or without CaCO₃ modification were not significantly different. The solid content of the CaCO₃ modified UF resin was significantly lower than that of the control group. In addition, the measured gel time of the CaCO₃ modified UF resin was 111–149 s, which was longer than that of the control resin (82 s). The gel time was further extended with the increase of the CaCO₃ content in the UF resin. The chemical group and crystal structure of UF resins with or without the modification of CaCO₃ were not significantly different. The internal bonding (IB) strength of the MDF panels significantly increased from 0.75 MPa to 0.97 MPa when the UF resin was modified with 2% of CaCO₃. This study provides scientific support for the preparation of inorganic mineral modified UF resins for strength enhanced wood-based panel manufacturing.

Reactions between CaCO₃ and CH₂O₂ during polycondensation of UF resin produce Ca²⁺. Ionic bond complexation binds Ca²⁺ with UF resin. The UF resin crystalline percentage decreases from 26.86% to 22.71%. IB strength of resin bonded fiberboard increases from 0.75 to 0.94 MPa.
