Comparison of efficacy of different surgeries for congenital severe ptosis / 国际眼科杂志(Guoji Yanke Zazhi)

Abstract?AIM: To comparatively analyze the efficacy and clinical value of cutting frontal muscular slap or not during frontalis aponeurosis flap suspension in treating congenital severe ptosis.?METHODS: Clinical data of 44 children ( 54 eyes ) with congenital severe ptosis treated in our hospital from May 2013 to October 2015 was retrospectively analyzed. Children included were divided into two groups according to the different ways of operation, observation group ( cutting frontal muscular slap ) and control group ( without cutting frontal muscular slap ) , 22 cases ( 27 eyes ) in each group. The general information, postoperative follow-up, eyelid closure and complication occurrence in two groups were compared.?RESULTS: The general information of the two groups had no statistical difference (P>0.05).After 1, 6mo, the cosmetic correction rate, the rate of overcorrection, and the rate of under correction in two groups had no statistical difference (P>0.05), but the activity of upper eyelid in observation group was bigger than that in control group (P0.05 ) , but eyelid fissure height in natural closed eyelids in control group was higher than that in observe group ( P<0.05 ).After 1mo, 2 eyes in control group were with abnormal feelings in frontal part, and 3 eyes in observation group.After 6mo, 2 eyes in control group were with abnormal feelings in frontal part, and 3 eyes in observation group.There were no complications such as exposure keratitis, eyelid margin deformity, infection, hematoma, and diplopia in two groups.?CONCLUSION: The total therapeutic effects of two different surgery procedures in treating severe congenital ptosis are quite similar.The surgery with cutting frontal muscular slap could improve the activity of upper eyelid and postoperative eyelid closure.

Synthesis and identification of rutin complete antigen and analysis its immunogenicity / 中国中药杂志

<p><b>OBJECTIVE</b>Synthesis and identification of complete antigen of rutin, the traditional Chinese medicine active ingredient, and develop rapid detection of rutin using enzyme-linked immunoassay method (ELISA). Immunogenicity of the complete antigen was also studied.</p><p><b>METHOD</b>Prepare the complete antigen by sodium periodate solution and identified by UV scanning and SDS-PAGE test. Male New Zealand white rabbits were immunized by the antigen to obtain the antiserum.</p><p><b>RESULT</b>The results of UV analysis showed that the coupling ratio of complete antigen is 13: 1. SDS-PAGE display of the artificial antigen was delayed compared with bovine serum protein. The titer of rutin antibody is 1:4 000. The sensitivity of IC50 was 5.37 mg x L(-1), the lowest detection limit was 1 mg x L(-1), the average recovery was 102%, the intra and interspecific RSD were less than 10%, cross-reactivity rate of antibodies and other analogs were less than 1%.</p><p><b>CONCLUSION</b>Rutin complete antigen was synthesized successfully, and the rapid detection of rutin by ELISA method was successfully established.</p>

Comparison of endoscopic ultrasonography with computer-assisted tomography in the determination of preoperative stage and resectability of pancreatic and ampullary cancers / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To study and compare the accuracy and sensitivity of endoscopic ultrasonography (EUS) and CT scaning in determination of preoperative stage and vascular invasion by pancreatic and ampullary cancers.</p><p><b>METHODS</b>Fourty-two pancreatic cancer patients and 18 ampullary cancer patients were studied. With patients prepared according to conventional endoscopy, Olympus EUM-30 scope 1 set with a side view and 360 degrees rotate and switchable scanning probe [ultrasound frequency (7.5/12 MHz)], was introduced to the descending duodenum through the esophagus. Gas within the duodenum and stomach was aspirated. Then, in order to to facilitate ultrasound transmission, 200 ml deaerated water was injected into the duodenum and 500 ml into the stomach to distend it. The structures of each part of pancreatic head and ampullary together with surrounding vessels were scanned. Then, the scope was withdrawn to the gastric antrum, body and fundus gradually, while the pancreatic body and tail were scanned.</p><p><b>RESULTS</b>Between Apr. 1996 to May 2004, a total of 42 pancreatic cancer patients and 18 ampullary cancer patients were examined by EUS. Meanwhile, all these 58 patients received preoperative CT scaning. The results of stage and vascular invasion determined by EUS in this series were as following; pancreatic cancer group (n = 42): accuracy in T2-4 stage was 100.0% (5/5), 75.0% (9/12) and 48.0% (12/25), respectively; ampullary cancer group (n = 18): T1-4 stage was 75.0% (3/4), 66.7% (2/3), 75.0% (6/8) and 33.3% (1/3), respectively; the accuracy in N stage: P-group: 80.0% in N1 (4/5), 90.0% in N0 (9/10); A-group: 50.0% in N1 (3/6), 91.0% in N0 (10/11). The sensitivity, specificity of vascular invasion, resectability and unresectablilty determined by EUS and CT as compared with surgical findings during operation was 52.9% (9/17), 93.1% (27/29), 77.1% (27/35) and 81.8% (9/11) for EUS (n = 60), respectively; and 11.8% (2/17), 92.6% (25/27), 62.5% (25/40) and 50.0% (2/4) for CT (n = 58), respectively.</p><p><b>CONCLUSION</b>Endoscopic ultrosonography being one of the best image examinations to determine the stage and vascular invasion for pancreatic and ampullary cancer paitients is able to detect small pancreatic or ampullary cancer less than 2.0 cm in diameter due to its high resolution; but can not detect the secondary multiple distal metastases such as spread into the liver, peritonium or hepatoduodenal ligament, etc. due to its ultrasound depth limitation.</p>
