Objective:This study aims to investigate the method and clinical outcomes of feeding tube placement and periopera-tive nutritional support for esophageal carcinoma patients. Methods:A total of 513 esophageal carcinoma patients who have undergone radical resection and reconstruction by a single operating group between January 2012 and December 2013 participated this study. Feed-ing tubes were inserted via the nasal path of 497 cases and by jejunostomy in 16 cases. Early enteral nutrition (EN) was administered through the feeding tubes 24 h postoperatively with a stepwise increase, whereas supplementation of parenteral nutrition (PN) was ter-minated until total EN. Results:Feeding tubes were successfully inserted in all patients during operation. No death or nutritional and metabolic disorders were documented during the observation period. No differences in anastomotic fistula, pulmonary complication, and incision infection were identified between the nasointestinal and jejunostomy groups (P>0.05). A higher incidence of intestinal ob-struction was observed in the jejunostomy group than in the nasointestinal group (P<0.05). Conclusion:Effective placement of nasoin-testinal tube and early enteral feeding are safe and effective methods for patients who have undergone esophagectomy for esophageal carcinoma.

Background Researches demonstrated that corneal dystrophy is associated with the mutation of transforming growth factor beta induced gene(TGFBI)located at chromosome 5q31 domine.Recent study showed that the gene mutation location is in R124H of TGFBI gene. Objective This study was to identify the mutation characteristics of TGFBI gene in a Chinese family with Avellino corneal dystrophy. Methods This Chinese family with Avellino corneal dystrophy were determined and surveyed in Peking University Third Hospital.Periphery blood from 8 patients with Avellino corneal dystrophy and 2 unaffected subjects were collected from a Chinese family with corneal dystrophy for the extraction of DNA.Exons 4,11,12 of the TGFBI gene were amplified by polymerase chain reaction(PCR),and the amplified products were sequenced directly and compared the gene sequence with that of TGFBI in GenBank.Written informed consent was obtained from each Subject prior to any medieal process. Results This family included 27 members of consecutive 4 generation.The hereditary pattern W88 in accordance with the autosomal dominant inheritance.Directly sequencing of 8 affected members revealed a G tO A transition at codon 124 (CGC to CAC),producing R124H mutation of TGFBI gene.Two synonymous single nucleotide polymorphism(SNP)of TGFBI gene occurred in the family.including a C to T transition at eodon 472(CTC to CTT)in 8 members,and a T to C transition at codon 540(TTT>TTC)in 9 members,which wag unrelated with disease. Conclusion R124H mutation of the TGFBI gene is found in this Chinese family with Avellino corneal dystrophy.

Objective To compare the survival rate of two kinds of neurovenofasciocutaneous flaps and investigate the venous reverse flow of flaps.MethodsTen New Zealand White rabbits were randomly allocated into 2 groups of 10 flaps(group A: the lesser saphenous sural pedicled fasciocutanous flaps,blood supply provided with perforator arteries;group B: the lesser saphenous sural pedicled fasciocutanous flaps,blood supply provided with axial type artery).The survival rate of flaps in two groups was observed.Pedicles of flaps were harvested and examined histologically.ResultsThe survival rate of flaps in group A was significantly lower than that in group B[(15.2?16.7)% vs(94.1?6.4)%,P

OBJECTIVEIsobaric tags for relative and absolute quantitation (iTRAQ) combined with mass spectrometry were used to screen differentially expressed plasma proteins in cold stress rats.

METHODSThirty health SPF Wistar rats were randomly divided into cold stress group A and control group B, then A and B were randomly divided into 3 groups (n = 5): A1, A2, A3 and B1, B2, B3. The temperature of room raising was (24.0 +/- 0.1) degrees C, and the cold stress temperature was (4.0 +/- 0.1) degrees C. The rats were treated with different temperatures until 12 h. The abdominal aortic blood was collected with heparin anticoagulation suction tube. Then, the plasma was separated for protein extraction, quantitative, enzymolysis, iTHAQ labeling, scx fractionation and mass spectrometry analysis.

RESULTSTotally, 1085 proteins were identified in the test, 39 differentially expressed proteins were screened, including 29 up-regulated proteins and 10 down-regulated proteins. Three important differentially expressed proteins related to cold stress were screened by bioinfonnatics analysis (Minor histocompatihility protein HA-1, Has-related protein Rap-1b, Integrin beta-1).

CONCLUSIONIn the experiment, the differentially expressed plasma proteins were successfully screened in cold stress rats. iTRAQ technology provided a good platform to screen protein diaguostic markers on cold stress rats, and laid a good foundation for further. study on animal cold stress mechanism.

OBJECTIVETo evaluate the clinical outcomes of primary anterior radical debridement, bone autograft, and sacral rod fixation for the treatment of tuberculosis of the lumbosacral segment.

METHODSFrom March 2004 to November 2008,11 patients with tuberculosis of the lumbosacral segments received antituberculosis medications for 2 to 3 weeks before anterior radical debridement, autologous iliac bone grafting, and internal sacral rod fixation. Among the patients, 5 patients were male and 6 patients were female, with an average age of (44.45 +/- 8.50) years (ranged from 29 to 56 years). The average time from stage of onset to operation was 11 months (ranged from 8 to 15 months). All the patients presented with various degrees of lower back pain; one patient experienced preoperative lower extremity radicular pain, while 2 patients experienced saddle area anaesthesia. However, only 6 patients exhibited mild to moderate tuberculous toxic reactions. All the patients were evaluated by plain radiography, computed tomography (CT), and magnetic resonance imaging (MRI). The diagnosis of tuberculosis was made with reference to clinical and radiological findings. Surgery was performed when the toxic symptoms of tuberculosis were controlled and erythrocyte sedimentation rates (ESR) decreased to (37.2 +/- 9.6) mm/h (25 to 54 mm/h). Lumbosacral angle, visual analogue scale (VAS) scores, ESR, and neurological performance were assessed before and after surgery.

RESULTSAll surgical procedures were performed successfully without intra or postoperative complications. There were no instances of spinal tuberculosis recurrence. Patients were followed up for a mean of (19.64 +/- 5.43) months. The mean lumbosacral angle significantly increased from the preoperative mean (12.9 +/- 5.0) degrees to postoperative (21.5 +/- 6.1) degrees and at final follow-up (20.1 +/- 5.2) degrees (P < 0.001). The mean VAS scores and ESR significantly decreased from preoperative (7.3 +/- 1.2) score and (37.2 +/- 9.6) mm/h respectively to final follow-up (0.6 +/- 0.5) score and (10.5 +/- 2.3) mm/h respectively (P < 0.001). Bone fusion occurred in all patients at a mean of (9.0 +/- 1.9) months (ranged 6 to 12 months) after surgery. Three patients who had impaired neurological performance before surgery had normal neurological performance after surgery.

CONCLUSIONOur findings suggest that anterior radical debridement, interbody fusion, and sacral rod fixation can be an effective treatment option for lumbosacral segment tuberculosis.

3-8 years old group(group C2) with 50 cases] were detected.A gonadotropin releasing hormone analogue(GnRHa) stimulation test was performed in 140 girls with IPT.The 140 girls were divided into 3 groups:IPT group,CPP group,and peripheral precocious puberty group(PPP group).Kruskal-Wallis and Mann-Whitneg tests were performed on the data between every groups.Results For basal LH levels,there were significant diffe-rences between IPT1 group and group C1,among IPT2 group,CPP group and group C2(Pa0.05).For peak LH/FSH ratios,there was significant difference between IPT2 group and CPP group(P

Objective: To observe the clinical efficacy of mind-refreshing and balance-restoring needling method combined with Frenkel exercises in treating ataxia after cerebral stroke. Methods: The recruited 120 patients were randomized into an observation group and a control group, with 60 cases in each group. The control group was intervened by mind-refreshing and balance-restoring needling method, while the observation group was given additional lower-limb Frenkel exercises. Before and after treatment and at the follow-up, the ataxic lower-limb function was scored using Berg balance scale (BBS) and international cooperative ataxia rating scale (ICARS), and Barthel index (BI) was adopted to score the activities of daily living (ADL). Results: After treatment, the markedly effective rate was 70.2％ and the total effective rate was 96.5％ in the observation group, versus 39.7％ and 87.9％ in the control group, and the differences in the markedly effective rate and the total effective rate were statistically significant (P<0.01, P<0.05). The intra-group comparisons showed that the BBS, ICARS and BI scores after treatment and at the follow-up were significantly different from those before treatment in both groups (all P<0.01).There were significant differences in the BBS score between the two groups after treatment and at the follow-up (P<0.05, P<0.01); the between-group differences in the ICARS and BI scores were statistically insignificant after treatment (both P>0.05), while the between-group differences in the ICARS and BI scores were statistically significant at the follow-up (both P<0.05). The interaction effects between the scoring time of BBS and BI and the group factor were statistically significant (P<0.01, P<0.05). Conclusion: Mind-refreshing and balance-restoring needling can effectively improve the lower-limb ataxic symptoms and ADL after stroke; when combined with Fenkel exercises, this needling method can produce more significant efficacy.
