Objective To investigate the clinical significance of gamete intrafallopian transfer (GIFT) under laparoscope. Methods The gonadotropin was adopted to induce superovulation and the spermatic fluid was managed with the swim-up method. After oviums were dislodged by puncture under laparoscope, gametes were transplanted by intubating the fallopian tube. Results Among a total of 19 patients, 4 were pregnant, the pregnancy rate being 21.1% (4/19). Three women had a delivery at term and 1 had an abortion. No serious complications were seen. Of the 15 unfertilized patients, normal pregnancy was observed within 6 months after surgery in 5 patients, the circle pregnancy rate being 5.6% (5/89). Conclusions GIFT under laparoscope is a practical assisted reproductive technique (ART) that may achieve a relatively high pregnancy rate. Some other pelvic diseases resulting in infertility can be treated simultaneously, which contributes to natural fertilization in the future.

Objective To establish a method for detecting K-rag gene point mutation in pancreatic adenocarcinoma based on the pyrosequencing and to compare its performance with that of Sanger sequencing.Methods Genomic DNA was extracted from formalin-fixed,paraffin-embedded pancreatic tissues including 49 pancreatic adenocarcinoma,10 normal pancreas,11 chronic pancreatitis,18 benign pancreatic tumor,7 insulin carcinoma,9 ampullary carcinoma,7 bile duct carcinoma and 7 duodenum papillary adenocarcinoma tissues.K-rag gene point mutations at codon 12 were analyzed by pyrosequencing and Sanger sequencing,respectively.Results No mutant K-ras gene Wag detected in normal pancreas,chronic pancreatitis,benign pancreatic tumor,insulin carcinoma,ampullary carcinoma,bile duct carcinoma and duodenum papillary adenocarcinoma tissues by either pyrosequencing or Sanger sequencing.K-rag gene point mutation was detection rate in pancreatic adenocarcinoma tissues was 71.4%(35/49)by pyrosequencing and 61.2%(30/49)by Sanger sequencing,respectively.Conclusions Pyrosequencing is more sensitive than Sanger sequencing and is also accurate,rapid and of high throushput in detecting mutant K-ras gene.It may serve as a practical method for fast batch analysis of clinical samples.

Objective To analyse the mutation of low density lipeprotein receptor (LDLR) gene associated with familial hypercholesterolemia (FH) and make a discussion on the relationship between genotype and phenotype. Methods The blood fat, electrocardiogram, heart and great vessels color Doppler were examined in propositus and family member. The promoter and all eighteen exons of LDLR gene were investigated by polymerase chain reaction (PCR),degenerate high performance liquid chromatogram (DHPLC) and DNA sequence analysis. The results were compared with the normal sequences in GenBank and FH database (www.ucl.uk/fh) to find the mutation. In addition,the apolipoprotein B100(ApoB100) gene for the known mutations(Q3500R) that cause familial defective ApoB100(FDB) was detected by directed screening.Results Two novel heterozygous c.1864 G→A (Asp622Asn) and c.1959 C→T(Val 653Val) mutations in the exon 13 of LDLR in promoter were detected. And Asp622Asn mutation segregated with the disease. No mutation Q3500R of ApeB100 was observed. Conclusions The heterozygous c.1864 G→A (Asp622Asn)mutation of LDLR gene is firstly determined in China. The heterozygous c.1864 G→A (Asp622Asn)mutation of LDLR gene is probably responsible for FH. Perhaps it is a particular pathogenesis for Chinese people. PCB-DHPLC could be used for detecting the mutation.

OBJECTIVETo compare the clinical effects of different surgical methods for the epicanthus corrective surgery.

METHODSCanthoplasty with asymmetric Z-flap is applied in 46 cases, Y-V advancement procedure for epicanthoplasty is applied in 42 cases. The epicanthus aesthetic measurement were measured and calculated by software before and after surgery, the diameter of the iris was measured as a reference value,and the postoperative scar was assessed by VSS scale. At the same time, by measuring the lateral canthal distance, the accuracy of the measurement method can be verified.

RESULTSAll patients were satisfied with the long-term results and there were no recurrences of the epicanthal fold. The shortening ratio of the ICD is 8.36% in the group with the Z-plasty, and 5.88% in Y-V plasty. the lateral canthal distance have no diffrence before and after surgery.

CONCLUSIONSTwo surgical methods can get good results. The magnitude of correction in Z-plasty may larger than Y-V plasty, but postoperative retraction may existed in Z plasty.
