Bilateral sequential cataract surgery is very common in clinical,but the ophthalmologists often ignore how to choose the timing of operation and whether the first eye can be used to improve the intraocular lens (IOL) power calculation for the second one.Despite the refinements in IOL selection with the use of third-generation IOL formulas,5％ of eyes still result in a postoperative refractive surprise of ± 1.00 D or more.This paper introduced the methods of using refraction error of the first eye to improve the IOL power calculation for the second eye,and the refractive error of the second eye can be improved by modifying the IOL power to correct up to 50％ of the error from the first eye in details.Because of the variation of the postoperative refractive surprise within a month,the interval of three to four weeks between two eyes cataract surgery is highly recommended.These conclusions may provide the advantageous guidance for us in the selection of IOL in bilateral cataract surgery.

OBJECTIVE: To characterize the pharmacokinetics of a single dose of 2.5 mg fondaparinux sodium in Chinese patients after thoracic surgery. METHODS: Thirteen patients were enrolled in the study and were given a single dose of 2.5 mg fondaparinux sodium via a subcutaneous injection. Plasma concentrations of fondaparinux sodium were measured throughout a 24 h period. The pharmacokinetic analysis was performed using WinNonlin software. RESULTS: The following pharmacokinetic parameters were derived; t1/2(7.92 ± 3.13) (4.21-15.89) h, tmax(2.52 ± 0.93) (1.38-4) h, p-1 (0.73 ± 0.18) (0.45-1.02) mg · L-1, AUClast(6. 56 ± 2.19) (3.07-9. 75)mg · h · L-1, Vz/F(3.54 ± 1.00) (2.24-5.73) L, CL/F(0.34 ± 0.14) (0.16-0.63) L · h-1, and MRTlast (6.98 ± 2.1) h. The pearson correlation coefficient, r was 0.7283(P = 0.005) between the serum creatinine(Scr) and mean residence time(MRTlast) of fondaparinux. CONCLUSION: The disposition of fondaparinux is highly variable in patients. A statistical significant correlation between Scr and MRTlast of fondaparinux was observed. Fondaparinux sodium administered by intravenous injection is well tolerated in patients.

A magnitude of 8.0 earthquake struck on Wenchuan on May 12, 2008. Until July 1, 1393 injured persons had been admitted to Deyang People's Hospital. Of all injured persons, 32 were diagnosed with abdominal injury, including 18 men and 14 women. All the abdominal injuries were closed injury, and multiple abdominal viscera were involved in the abdominal injuries after the earthquake. Careful examination is crucial in preventing missed diagnosis. The incidences of the liver and spleen injuries were significantly higher than that of the intestine, and the reason may be that the liver and spleen are the parenchymal viscera. Diagnostic abdominocentesis can timely diagnose the parenchymal viscera with severe blood loss. Diagnostic peritoneal lavage combined with selective CT scan can timely diagnose the abdominal injuries with comparatively low cost.

Superficial siderosis of the central nervous system is a seldom disease in clinical practice. Its most common clinical manifestations are hearing loss and ataxia. It is a hemosiderin deposition in the surface of the brain and spinal cord after chronic subarachnoid hemorrhage. Magnetic resonance imaging can make the diagnosis. However, further research and clinical verification are needed.

To investigate the cause of donor death in living donor liver transplantation(LDLT), we reviewed all published articles in English on LDLT from the Foreign Medical Journal Full-Text Service (FMJS) and searched the literature for donor deaths before 2008. We identified 12 donor deaths. The rate of donor death is 0.2%. Any donor death would be a catastrophe for the donor's family and for the medical team. It is imperative to avoid donor death in LDLT.

ObjectiveTo explore the application of enlargement of plastic surgery for dural closure with radial neuro-patch in standardize large decompressive craniectomy (SLDC).MethodsTwenty-one patients (observation group) who needed a SLDC for various reasons were treated with radial incision in dura to release the high intracranial pressure and enlargement of plastic surgery for dural closure with radial neuropatch from March 2009 to June 2010.The neuro-patch were used as the dural substitutes.Twenty-one patients were treated with SLDC only for the similar reasons (control group).General healing effects were compared betweentwo groups.ResultsIn 6 hours and 72 hours after surgery,the rate of obvious effectiveness in observation group was significantly higher than that in control group [33.33％(7/21 ) vs.14.29％(3/21 ),33.33％(7/21 ) vs.19.05％(4/21 ) 、61.90％( 13/21 ) vs.28.57％(6/21 ),61.90％( 13/21 ) vs.38.10％(8/21 )](P ＜ 0.05).The rate of intracranial infection,cerebrospinal leak and epilepsy in observation group [0,0,4.76％ ( 1/21 )]was significantly lower than that in control group [14.29％ (3/21),14.29％ (3/21),19.05％ (4/21)](P ＜0.05).The rate of subcutaneous or subdural cerebrospinal fluid accumulation,cenencephalocele,cerebral ventricular malformation,brain hernia through the skull window had no significant difference between two groups [19.05％(4/21 ),0,4.76％( 1/21 ),0 in observation group;23.81％(5/21 ),9.52％(2/21 ),9.52％(2/21 ),4.76％( 1/21 ) in control group) (P ＞ 0.05 ).After followed up of 6-12 months,the rate of the well general outcome in observation group was significantly better than that in control group [85.71％ ( 18/21 ) vs.71.43％ ( 15/21 )](P ＜ 0.05 ).The rate of moderate-critical function handicapped in control group was significantly higher than that in observation group [23.81％(5/21 ) vs.9.52％(2/21 )](P＜0.05 ).ConclusionsThe SLDC is effective for decreasing the intracranial pressure,and the enlargement of plastic surgery for dural closure with radial neuro-patch can improve the efficiency and decrease the incidence of complicating diseases.This therapy can improve the patients' general quality of survival and is worth to be popularized in clinic.
