AIM: To determine the optimal operation method and reduce operative complications by retrospective analysis of outcomes of different operative manipulation for patients with congenital ectopia lentis ( CEL) .
●METHODS: A retrospective study ranged from Jan. 1, 2010 to Jan. 1, 2015 was conducted and 31 CEL patients (57 eyes) treated with different operations were taken into this study. The postoperative outcome, operation related complications was analyzed in terms of different operative manipulations.
● RESULTS: The most common types of CEL are idiopathic and Marfan - related CEL. All eyes ( 98%) benefited from operation except 1 Marchesani syndrome eye concurrent with optic atrophy induced by glaucoma. A total of 3 eyes ( 5%) were treated by phacoemulsification combined with intraocular lens implantation; 8 eyes ( 14%) were treated by phacoemulsification, capsular tension ring implantation combined with intraocular lens implantation, among these 8 eyes, 1 eye was treated with capsular tension ring implantation combined with suture fixation; 39 eyes ( 68%) were treated by lens excision and anterior vitrectomy through corneal incision combined with intraocular lens implantation with suture fixation, among these 39 eyes, 2 eyes were treated with trabeculectomy , but not combined with intraocular lens implantation; 5 eyes ( 9%) were treated by intracapsular cataract extraction and anterior vitrectomy combined with intraocular lens implantation with suture fixation; 2 eyes ( 4%) were treated by lens excision and vitrectomy through pars plana combined with silicon oil injection.
● CONCLUSION: Almost all patients can obtain satisfactory outcomes through various operative manipulations. Phacoemulsification combined with intraocular lens implantation was the first choice for patients with lens dislocation range less than 90°. Phacoemulsification, capsular tension ring implantation combined with intraocular lens implantation was recommended for 90° - 180°, and lens excision and anterior vitrectomy through corneal incision combined with intraocular lens implantation with suture fixation was more suitable for lens dislocation range more than 180°. The appropriate operative methods for different types of CEL patients is the key to success.

Objective To detect the antiplatelet function of clopidogel by Thrombelastography (TEG)and light transmmi-tance aggregometry (LTA)and analyze efficiency of two methods.Methods ①Venous blood samples were taken from 48 outparients and inpatient with acute corotary syndrome (ACS)in PLA General Hospital,including unstable anqina,ST seg-ment elevation myocardial infarction and non ST segment elevation myocardial infarction (32 males,16 females)by random number table from March to July 2011,whose average age was 73 (62~90).②All of them were served 160 mg aspirin and 300 mg clopidogrel after they were in hospital at first time,and then served with 75 mg/d clopidogrel for 9 months.After that,venous blood samples were drew from them who were served clopidogrel 2 hours later.③Platelet aggregation function was assayed with LTA and TEG.All volunteers were signed informed consent and the experiment was approved by the hos-pital ethics committee.Results The platelet aggregation rate detected with LTA induced by adenosine diphosphate (ADPL-TA-INDU)was 40~80% in 41 individuals (85.4%),>80% in 7 individuals (14.6%),coefficient of variation (CV)was 0.19.The inhibition ration of platelet function (INHI)detected with TEG (ADPTEG-INHI)was 10~60% in 40 individu-als (83.3%),<10% in 2 individuals (4.2%),>60 in 6 individuals (12.5%),CV was 0.54.The sum of ADPLTA-INDU and ADPTEG-INHI (ADPLTA-INDU+ADPTEG-INHI)tended to a constant (Mean=98%,SD=12.1).There was no significant indifference between every (ADPLTA-INDU+ADPTEG-INHI)and their Mean (98%)by paired t-test.The ADPLTA-INDU was negative correlated with ADPTEG-INHI (r=-0.75,P<0.01).Conclusion The effect of clopidogrel was mild and the efficiency of TEG and LTA was similar in detecting the antiplatelet function of clopidogrel,but the preci-sion of TEG was lower than LTA.

Objective To investigate the role of APRIL in SW480 cell line.Methods The CRC model was established in the nude mice,all the mice were divided into 3 groups,the mice were separately treated with APRIL siRNA,pGC-vector and PBS solution.The APRIL mRNA was detected by RT-PCR and the APRIL protein was surveyed by the way of immunohis-tochemistry (IHC).The proteins of TIMP-3,Syndecan-1and MMP-9 also were assessed by IHC.Results ①Tumor mass in the group of nude mice injected with PBS (2.15±0.30 g)was significantly higher than the injection APRIL siRNA group (0.95±0.15 g,P<0.05),and was not statistically significant (P>0.05)compared with the injection of empty vector group (2.20±0.25 g).②APRIL mRNA/18S rRNA ratio (2.48±0.25)in the group of mice injected with PBS was signifi-cantly higher than the injection APRIL siRNA group (0.39±0.15,P<0.05),and was not statistically significant (P>0.05)compared with the injection of empty vector group (2.51±0.30).③SW480 cells injected with APRIL siRNA signifi-cantly inhibited invasion and metastasis.TIMP-3 Allred scores in three groups were 7.70±0.35,1.10±0.16 and 1.15± 0.12,Syndecan-1 protein was 7.80±0.30,1.05±0.20 and 1.10±0.22 MMP-9 protein was 1.20 ±0.10,8.00±0.25 and 8.20±0.20,respectively.Conlusion APRIL was closely connected with the growth and metabasis of CRC.

Objective To explore a new method of functional reconstruction of hand digits and joints with free transfer of foot tissues so as to increase the success rate of the operation.Methods After micro-anatomic study of the plantar and dorsal metatarsal arteries,retrograde and free grafts of foot tissues pedicled with plantar metatarsal arteries were designed and applied in transplantation to treat 76 cases of hand digital or joint defects.The surgeries included 58 cases of transfer of the second toe,four cases of transfer of composite tissues of the second toe, eight cases of transfer of proximal interphalangeal joint,and six cases of nail flap transfer.Results The mi- cro-anatomic study found that the first plantar metatarsal artery was anatomically constant and the diameter of its branch to the second toe was larger than that of the first dorsal metatarsal artery.Flaps survived in 75 of the 76 patients(98.7%),with fine appearance and significantly improved function.One patient who had received free transfer of the second toe to reconstruct the thumb function had to undergo a second repair with infraclavicula skin tube because of refractory arteriospasm of anastomosed vessels.Conclusion Transfer with free retrograde grafts of foot tissues pedicled with plantar metatarsal artery to reconstruct hand functions can effectively improve the success rate of the operation,because it is free of the shortcomings of great anatomic variation of blood vessels and time-consuming and complex procedures in conventional transfer.

OBJECTIVETo investigate the characteristics of the phenylalanine hydroxylase (PAH) gene mutations in patients with phenylketonuria (PKU) in Henan province, China, in order for providing basic information for clinical genetic counseling and prenatal diagnosis.

METHODSAll the exons and partial flanking introns of the PAH gene were detected by polymerase chain reaction (PCR) and bi-directional sequencing in 34 patients with PKU from Henan province.

RESULTSA total of 23 different disease-causing mutations were identified which corresponded to 92.65% (63/68) of the PAH alleles, including 12 missense mutations, 4 nonsense mutations, 4 splicing junction mutations, and 3 deletion mutations. Among them, A156P and P69_S70delinsP(delCTT) were novel mutations; IVS2+ 5G to C, G332E, IVS10-14C to G and L367 to Wfs were reported in Chinese population for the first time according to the PAH database (www.pahdb.mcgill.ca). Among all the 13 exons, exon 7 harbored the most type of mutations, exon 11 and exon 5 the second. The most common mutations included R243Q (17.65%, 12/68), V399V (11.76%, 8/68), IVS4-1G to A (8.82%, 6/68), R400T(7.35%, 5/68), Y166X(5.88%,4/68) and G247R(5.88%, 4/68). In addition, 9 other gene variations were found in this study.

CONCLUSIONThe mutation spectrum and frequency of the PAH gene of patients with phenylketonuria in Henan province were slightly different from those from other parts of China.
