The clinical significance of pyloroplasty in the proximal gastrectomy / 重庆医学

Objective To explore the clinical effects of pyloroplasty on proximal gastrectomy in patients with lesions in cardia of the bottom of stomach.Methods One hundred cases of the proximal gastric diseases who were enrolled in the second affiliated hos-pital of Chongqing medical university from the January 2010 to December 2013 were selected in this prospective randomized con-trolled experimental study.Among them,6 cases were excluded,and the other 94 cases were divided into two groups:the experimen-tal group (A),in which 54 patients were underwent additional pyloroplasty surgery;the control group (B),in which 40 patients were underwent with no strings attached pyloroplasty.All patients were followed up.Then,the clinical indicators during hospitaliza-tion,term complications and repeated endoscopy prompted pyloric stenosis and reflux esophagitis situation three months after dis-charged from hospital were observed.Results There was no significant difference in the incidence rate of gastroplegia (P >0.05);there were significant differences in other clinical indicators during the postoperative hospitalization and the incidence rate of compli-cations (P <0.05).Conclusion Proximal gastrectomy additional pyloroplasty could reduce gastric retention,decrease the incidence of reflux esophagitis,shorten the hospital period and could be helpful for recovery,thus it is recommended to be further promoted.

THE GROWTH OF THE FEMUR OF CHINESE FETUS AND IT'S CORRELATION-RATIO WITH THE C-R LENGTH / 解剖学报

The femurs of 98 Chinese fetuses were observed and measured with radiographic method. A series data of femur-length and -width of different fetal-age groups was obtained. Calculated femur index (width/length?100)showed that the proportion between the femural length and the femural width remained considerably constant dur- ing the development of the fetus. The positive correlation between the length of the femur and the C-R length was revealed by statistical analysis; a regression equation was obtained. The authors suggest that it is possible to take the femural length as a criterion parameter to estimate the fetal age.
