Objective To elucidate association between the mutation of nuclear factor of activated T cells 1 ( NFATC1 ) gene in IPT-NFAT region and simple congenital heart disease (CHD) in children. Method We used polymerase chain reaction (PCR) and the sequencing reaction to detect the mutations on the patients and their parents and (or) siblings. Results PCR amplification of the exon 7 region showed that 2 bands are obtained in 58% of patients with CHD and in 74% of their healthy parents and (or) siblings. Sequencing of the 2 bands revealed that both are amplicons of the exon 7 region, and that the additional band harbors an additional 44 nucleotides segment in the intronic region. The homozygous form of this allele was only present in patients with ventricular septal defect (2/24), atrial septal defect (3/18) and bicuspid aortic valve (1/4) in which G to A transition at nucleotide 17 of the third 44 bps was found. Neither the unrelated non-CHD individuals nor the ones with other CHD showed positive presence for the homozygous form of this allele. Conclusions There is a differential amplification of a tandem repeat region in intron 7 of NFATC1 and homozygous form of this allele in patients with ventricular septal defect, atrial septal defect and bicuspid aortic valve. NFATC1 gene may be an a susceptibility marker for ventricular septal defect, atrial septal defect and bicuspid aortic valve.

OBJECTIVETo evaluate the relationship between idiopathic Parkinson's disease (PD) and two polymorphisms (C243G and A377T) of the gamma-synuclein gene in a Chinese Han population of Shanghai area.

METHODSPolymorphic genotyping was performed with PCR-RPLP technique. Association analysis was carried out in 145 unrelated idiopathic PD patients and 184 age-matched healthy controls.

RESULTSThe authors failed to detect any distributional difference of the C243G and A377T polymorphisms of the gamma-synuclein gene between PD cases and control subjects, nor did they find any association.

CONCLUSIONThese data do not support that gamma-synuclein gene C243G and A377T polymorphisms are involved in idiopathic PD onset in the Han population of Shanghai area.

OBJECTIVETo systematically assess the effect of early enteral nutrition support after gastrointestinal operation on prognosis.

METHODSThe Cochrane Library, PubMed, CBM, CNKI, Wanfang, and VIP databases were retrieved via computer system for randomized controlled trails(RCTs) with early enteral nutrition support to patients undergoing gastrointestinal operation. Quality of studies was evaluated by the Cochrane Jadad rating scale. Nutrition indexes, bowel function indices, postoperative complications, health-economics indices were collected. Meta-analysis was conducted with RevMan 5.2.

RESULTSEleven relevant RCTs studies with 1087 cases were enrolled, including 541 patients in the study group(early enteral nutrition) and 546 in the control group. Meta-analysis showed that patients in the study group had significantly higher levels of plasma albumin and prealbumin than those in the control group(WMD=2.87, 95%CI:1.03-4.71; WMD=0.04, 95%CI:0.02-0.05). The time of postoperative bowel ventilation in the study group was significantly shorter than that in the control group(WMD=4.10, 95%CI:-5.38--2.82). The postoperative complication rate in the study group was significantly lower as compared to the control group(RR=0.64, 95%CI:0.44-0.93).

CONCLUSIONEarly enteral nutrition support after gastrointestinal operation is safe and effective, which can improve the nutritional status, promote bowel function return, and reduce postoperative complication rate.

OBJECTIVETo compare the difference of protein expression in the supernatant of heat injured keratinocytes (KC) and normal KC.

METHODSA model of heat injured KC was produced in vitro. The supernatant of normal KC and heat injured KC was collected after culture for 12 hours, and was ultrafiltered and lyophilized to get the protein. The protein sample was separated by immobilized pH gradient based two dimensional gel electrophoresis (2-DE). The gel was stained and the different expression of protein was analyzed using ImageMaster 2D analysis software.

RESULTS(1) Average protein spots were 1,898 +/- 113, 1,877 +/- 97 in the supernatant of normal and heat injured KC and 1,118 protein spots could be used for statistical analysis. (2) Statistical result showed that 26 protein spots were significantly different between the two groups. 16 protein spots were higher in the supernatant of normal KC and then 10 protein spots were lower in the normal group. (3) 16 protein spots, which included 10 kinds of proteins, were identified successfully as different spots. Lower expression proteins were alpha-enolase, actin cytoplasmic 2, peroxiredoxin-4, phosphoglycerate mutase 1, G protein-regulated inducer of neurite outgrowth l in the supernatant of heat injured KC. Higher expression proteins in heat KC were purine nucleoside phosphorylase, tumor necrosis factor ligand superfamily member 10, proteasome subunit alpha type-7, UDP-glucose 6-dehydrogenase in the supernatant of heat injured KC.

CONCLUSIONSThe result indicated that there are some significant different expression proteins in the supernatant of normal KC and heat injured KC. These findings provide new data for screening major molecules of tissue repair and finding the mechanism of wound repair.

OBJECTIVETo investigate the relationship between cyclooxygenase-2 (COX-2) mRNA expression and the biological behaviors of prostate carcinoma (PCa).

METHODSThe expression of COX-2 mRNA was detected by RT-PCR method in 32 samples of PCa and the COX-2/GAPDH value was determined. Seven normal prostate tissues were served as control.

RESULTSThe expression of COX-2 mRNA in normal tissue of 7 control cases was all negative. There was statistical correlation between the COX-2/GAPDH and the Gleason scores of PCa. There also showed statistical correlation between the COX-2/GAPDH and the stages of PCa.

CONCLUSIONCOX-2 mRNA play an important role in occurrence and progression of the PCa. COX-2 is a tumor marker which may be the possible prognostic factor of PCa.

To provide a scientific evidence for the initial primary processing method, an ultra-high performance liquid chromatography combined with a triple quadrupole electrospray tandem mass spectrometry (UPLC-MS/MS) was used to analyze the contents variation of catechins, flavonoids, flavonoid glycosides, biflavones, terpene lactones and phenolic acids during the process of drying in the sun, in the shade, and baked with 35, 45, 60, 80 degrees C, respectively. The results show that drying in the 80 degrees C is conducive to the accumulation of catechins, flavonoid glycosides, terpene lactones, better than the effects of other procedures. Therefore, the fast drying at 80 degrees C is beneficial for the retention of various types of active ingredient of Ginkgo biloba, and this method could be applied as a preferably dry processing.

OBJECTIVETo investigate the feasibility of repairing the wounds in the distal feet with dorsal metatarsal artery distal perforator pedicle link-pattern flaps.

METHODSSince January of 2004 to April of 2009, 30 patients with distal wounds in the feet underwent surgical wound repair using by dorsal metatarsal arteries distal perforator pedicle link-pattern flaps. Seventeen patients used the 1, 2 dorsal metatarsal artery distal perforator flaps, and 13 had the 3, 4 dorsal metatarsal artery distal perforator flaps, with the flaps measuring 4 cmx4 cm to 8 cmx7cm and the flap pedicle ranged 3-6 cm in length. The donor sites were repaired with skin grafting.

RESULTSTwenty-nine flaps survived completely and 1 flap showed partial necrosis in the distant part (2.0 cmx1.0 cm). Twenty-one patients were followed up for an average of 11 months, during which the color, texture, and contour of the flaps remained normal without ulcers in the donor sites or the flaps.

CONCLUSIONThe wounds in the distal feet can be repaired by dorsal metatarsal artery distal perforator pedicle link-pattern flaps, which is a simple, applicable and safe procedure.

OBJECTIVETo investigate the feasibility of fibular artery perforator link-pattern flaps at lateral and posterior part of legs.

METHODSFrom January 2007 to March 2009, 12 cases of with feet and ankle wounds were treat with fibular artery perforator link-pattern flaps at lateral and posterior part of legs. The flap size ranged from 10 cm x 10 cm to 25 cm x 13 cm. The wounds at the donor sites were closed with skin grafts.

RESULTSAll the flaps survived completely. The patients were followed up for 1-12 months (median, 6 months). The color, texture and appearance of the flaps were good.

CONCLUSIONThe link-pattern flap has reliable blood supply and a large area for repairing defects. The sural nerve is reserved, resulting minimal morbidity to donor site.
