?AlM: To evaluate the clinical efficacy of posterior continuous curvilinear capsulorhexis ( PCCC ) combined with anterior vitrectomy in preventing posterior capsule opacification of congenital cataract surgery.
?METHODS:Postoperative clinical follow-up data of 82 cases ( 87 eyes ) with congenital cataract treated in Eye Center of our hospital from January 2011 to August 2014 were retrospectively analyzed. The patients were divided into the surgical control group ( 38 cases, 40 eyes, recieved phacoemulsification + PCCC ) and the study group ( 44 cases, 47 eyes, accepted phacoemulsification+ PCCC + anterior vitrectomy). The incidence of central optic axis opaque and postoperative visual acuity distribution were recorded at 1a follow - up. lntraoperative and postoperative complications were observed.
?RESULTS:The rate of central optic axis opaque grade 0 in control group was 37. 5%, compared to 76. 6% in study groups. The opacity distribution ratio of grade 1,2,3 and 4 in study group were lower than that of control group, and the central optic axis opacity distribution ratio in study group was significantly better than that of control group (P<0. 05). The 19 eyes(47. 5%) of visual acuity testing ≤0. 5 in control group , was higher than the 7 eyes(14. 89%) of that in the study group, The 21 eyes (52. 5%) of visual acuity testing >0. 5 in control group was lower than the 40 eyes ( 85. 11%) of that in study group. The visual acuity between two groups has statistical significance difference after 1a follow-up ( P<0. 05 ) , and the visual acuity in study group was significantly better than that in the control group. The postoperative intraocular pressure at 1mo and 1a follow-up was lower than before operation in two groups ( P<0. 05), but there was no significant difference between two groups in intraocular pressure (P<0. 05).
?CONCLUSlON: Combination of phacoemulsification, PCCC and anterior vitrectomy presents reliable clinical effects on postoperative central optic axis opacity distribution ratio and visual acuity, and it should be adopted to prevent the occurrence of posterior capsule opacification.

Persicae Semen (PS), a traditional Chinese medicine, has been widely used for the syndrome of blood stasis in China since the Eastern Han Dynasty. In the present study, we developed an HPLC-UV fingerprint analysis method for the quality control of PS. The HPLC fingerprint was performed on Shimadzu Inertsil C18 column (4.6 mm x 250 mm, 5 microm) at 35 degrees C. The mobile phases were composed of acetonitrile and water using a gradient elution. The flow rate was 1.0 mL x min(-1), and the detection wavelength was set at 210 nm. The fingerprint method was validated according to the Guidelines for Traditional Chinese Medicine Injection Fingerprint, and applied to determine 41 batches representative herbs collected from Xinjiang of China. The chromatographic peaks were characterized by UPLC-Q-TOF-MS, and nine of them were identified by comparison with the literature and/or reference standards. In order to classify and assess the samples, hierarchical clustering analysis and partial least square discriminant analysis were performed based on the common chromatographic peaks, and the samples were geographically classified into two classes, with six chemical compounds as classification markers which were significantly different between the two classes (P < 0.05).

A novel serine protease with high purity was extracted from the venom of Agkistrodon hlays Pallas using monoclonal antibody affinity chromatography. This protease releases bradykinin and has arginine esterase activity without being activated. After purification, its hydrolytic activity exceeded 800 U/mg, far higher than its counterparts from mammalian sources. The purity of the kininogenase could exceed 95%. The acute toxicity and the long-term toxicity of this kallikrein was studied for its potential clinical application. The maximum tolerance dose in adult was 150,000 times greater than the maximum applied dose, and long-term administration at the dose 50 times of allowed clinical dose did not obviously after the animals' body weight, survival condition, liver function, renal function, or blood routines, suggesting the extremely low toxicity of the kallidrein.

Objective To study the regiments of continuous subcutaneous insulin infusion (CSII) in admitted type 2 diabetic patients, and to analyse the factors related to its effectiveness and insulin dosage. Methods A total of 1 276 type 2 diabetic patients were treated by CSII. The total efficacy of CSII was evaluted. The use of CSII was also analysed in the newly diagnosed patients, elderly patients, and patients with obese or infectious disease. Results The excellent control of blood glucose were achieved in (5.7±2.6)days in the dosage more early and quickly in the newly diagnosed group than that in the previously diagnosed group after the blood glucose levels achieved good control. The percentage of the patients reached the clinical relieve was also higher in the newly diagnosed group. The incidence of hypoglycemia was significantly higher in the elderly patients with lower basal insulin dosage at night. The bolus insulin dosage in the obese patients was higher than that in the non-obese patients. The patients with infectious disease usually have a higher basal insulin dosage than those without infectious disease. The days needed for achieving good control of blood glucose and the insulin dosage were related to infectious factors, the basal blood glucose and obesity. Conclusion The application of CSII among the patients is varied with different conditions. Blood glucose level, body mass index and infection factors are important to determine the initial insulin dosage.
