ABSTRACT
Objective@#To investigate whether rapid weight gain in the first year of life was associated with incidence of overweight and higher blood pressure in small for gestational age (SGA) and appropriate for gestational age (AGA) infants at preschool age.@*Methods@#From March 1, 2017 to June 30, 2018, a total of 12 150 children aged six years from 50 municipal kindergartens in Tianjin were enrolled in a cross-sectional survey. Their body weight, height and blood pressure were measured. Body length and weight at birth and one year of age were retrospectively collected. Rapid catch-up growth was defined as the difference of weight-for-height Z-score between one year old and at birth >0.67. The relationship between rapid growth with overweight and blood pressure in SGA and AGA infants at preschool age were analyzed using t test, analysis of variance and Chi-square test.@*Results@#At the age of six, children with rapid growth had a higher rate of overweight [28.6% (2 095/7 328) vs 17.5% (842/4 822), t=196.457, P<0.001], and higher systolic blood pressure [(99.4±10.0) vs (98.4±10.1) mmHg (1 mmHg=0.133 kPa), t=29.260, P<0.001] and diastolic blood pressure [(60.0±7.7) vs (59.4±7.8) mmHg, t=16.079, P<0.001] compared with children without rapid growth. SGA children with rapid growth had higher body weight [(21.5±4.4) vs (19.2±3.7) kg, t=3.747, P<0.001], height [(117.4±5.5) vs (114.8±5.4) cm, t=3.557, P<0.001] and systolic blood pressure [(98.4±9.9) vs (95.6±11.2) mmHg, t=2.080, P=0.038] compared with those without. Comparing to AGA children, SGA children had lower overweight rate [17.5% (144/824) vs 24.7% (2 793/11 326), t=21.630, P<0.001] and systolic blood pressure [(98.2±10.0) vs (99.0±10.1) mmHg, t=2.431, P=0.015]. Among the AGA children with rapid growth, 29.8% (1 958/6 564) were overweight.@*Conclusions@#Rapid growth in infancy is associated with overweight and higher systolic blood pressure at preschool age. A proper weight gain should be emphasized for both SGA and AGA infants.
ABSTRACT
Objective To evaluate the results of anal function and oncologic effect of intersphincteric resection(ISR) for very low rectal cancer Methods Sixteen patients who had ISR from March 1999 to March 2006 in our hosptal.After complete dissection of the rectum and mesorectum down to the pelvic floor,the internal sphincter was separated from the external sphincter and puborectalis and resected together with the rectum,then the coloanal anastomosis was performed.On postoperative day 7,the anal contraction function training was started;on week 4,biofeedback training was started;on week 2,chemotherapy was used for Dukes B,C stage,and on week 4 radiotherapy was used.Results There was no operative mortality,and no anastomotic leakage.Colonic mucosa prolapse developed in two patients,two developed late strictures of the coloanal anastomosis and one had wound problem.At follow-up of 3 months to 7 years,there were 2 deaths from liver metastasis and 1 death from lung metastasis;no patient developed local recurrence.According to Williams continence status level,acceptable postoperative anal function were obtained in 62.5 %,80.0 %,and 84.6 % of patients at 3,6,and 12 months respectively.Conclusions ISR is safe for selected patients with very low rectal tumor,operative morbidity is low,and the curability rate and anal functional results are satisfactory.
ABSTRACT
Objective To study the clinical significance of expression of survivin gene in transitional mucosa(TM) adjacent to rectal carcinoma.Methods Mucinhistochemical methods were used to observe the distribution of TM adjacent to rectal carcinoma, and using immunohistochemical methods to observe the expression of survivin gene product in TM,normal mucosa,atypical dysplasia and cancer tissue.Results The positive expression level of survivin gene product was lowest in normal rectal mucosa,and gradually increase in TM,dysplasia and carcinoma tissue(all P
ABSTRACT
Objective To detect the correlation of serum p53 antibody and p53 protein expression of cancer tissue in patients with colorectal cancer (CRC), and to evaluate if the serum p53 antibody might reflect the mutation of p53 gene in CRC. Methods One hundred and thirty-two patients with CRC and 36 patients with non-tumor disease were included in this prospective study. The presence of serum p53 antibody was determined by enzyme-linked immunosorbent assay (ELISA). Immunohistochemical analysis of tumors was performed to detect the accumulation of p53 protein. Results The positive rate of p53 antibody was 40.2% in patients with colorectal cancer and 2.9% in non-tumor patients,( P
ABSTRACT
Objective To investigate the outcome of low anterior resection of rectal cancer with double stapling technique.Methods A retrospective analysis of clinical records of 78 rectal cancer patients who had anal preservation operation using double stapling technique was performed.Results In all of the cases,the rectal closing and anastomosis were satisfactorily completed.All the resection margins were negative for tumor infiltration.There was no operative mortality or anastomosis leakage.Seventy-three(93.6%)cases were followed up for 9-65 months,pelvic recurrence occurred in 2 cases(2.7%),multiple metastasis of peritoneal cavity occurred in 1 case(1.4%),liver metastasis was found in 7 cases(9.6%),one patient suffered from local recurrence and Miles operation was performed 11 months later.Conclusions Double stapling technique can provide more chances for sphincter preservation operation in patients with lower rectal cancer.If the technique is properly used,it also may effectively reduce the rate of anastomosis leakage and other complications.
