OBJECTIVETo evaluate the benefits of post-stenting radiotherapy and/or chemotherapy for unresectable esophageal carcinoma.
METHODSFifty-three patients with unresectable esophageal carcinoma were randomly divided into two groups: patients in group A (n = 27) were treated with stenting alone, and those in group B (n = 26) were treated with stenting followed by radiotherapy and/or chemotherapy. Comparison was made by assessing their survival time, quality of life (QOL), degree of dysphagia, and stenting-related morbidity, respectively.
RESULTSThere was no statistically significant improvement in dysphagia and QOL between the two groups. Although there was no difference in the frequency of stenting-related complications, re-stenosis occurred much less frequently in group B patients (P = 0.007). The mean survival time of patients was 245 +/- 41 days and 262 +/- 43 days in group A and group B, respectively. There was no significant difference between the two groups (P = 0.813).
CONCLUSIONBesides decreased recurrence of stenosis, post-stenting radiotherapy and/or chemotherapy does not provide additional benefits for survival.

OBJECTIVE:
To investigate the influence of pre-pregnancy parental body mass index (BMI), maternal weight gain during pregnancy, and their interaction on neonatal birth weight.
METHODS:
A total of 1 127 pregnant women who underwent regular prenatal examinations and full-term singleton delivery in the First Hospital of Xi'an Jiaotong University from January 2017 to October 2018 were enrolled. The data on their pre-pregnancy BMI, maternal weight gain during pregnancy, pre-pregnancy BMI of the husband, and neonatal birth weight were collected. The interaction between pre-pregnancy parental BMI and maternal weight gain during pregnancy was analyzed, and their correlation with neonatal birth weight was analyzed.
RESULTS:
Among the 1 127 full-term neonates, the detection rates of low birth weight neonates and macrosomia were 2.22% (25/1 127) and 3.82% (43/1 127) respectively. There were significant differences in pre-pregnancy parental BMI and maternal weight gain during pregnancy among the low birth weight, normal birth weight, and macrosomia groups (P<0.05). Neonatal birth weight was positively correlated with pre-pregnancy parental BMI and maternal weight gain during pregnancy (r=0.097-0.322, P<0.05). Low maternal weight before pregnancy increased the risk of low birth weight (RR=4.17, 95%CI: 1.86-9.38), and maternal overweight/obesity before pregnancy (RR=3.59, 95%CI: 1.93-6.67) and excessive weight gain during pregnancy (RR=3.21, 95%CI: 1.39-7.37) increased the risk of macrosomia. No interaction between pre-pregnancy maternal BMI and maternal weight gain during pregnancy was observed.
CONCLUSIONS
Pre-pregnancy parental BMI and maternal weight gain during pregnancy are related to neonatal birth weight, and there is no interaction between pre-pregnancy maternal BMI and maternal weight gain during pregnancy.

OBJECTIVETo find out the occurrence of cesarean section (CS) and to probe the factors associated with CS.
METHODSWomen with CS as "case group" and women without CS as "control group" were chosen in a case-control study.
RESULTSAmong 14 071 childbirth women, 6 421 had CS (case group) with the occurrence rate of 45.6% and 7 650 (54.4%) had normal delivery (control group). In comparison with the control group, the CS group had following several higher rates [with significant differences between case group and control group (P < 0.01)]: well-educated (78.9% vs 69.5%), white collar jobs (38.0% vs 32.3%), urban residents (79.1% vs 70.6%), high monthly income (>/= 500 Yuan) (81.0% vs 70.6%), of older age (>/= 25 years) (73.3% vs 63.0%), heavier baby weight (> 4 000 gram) (8.3% vs 2.9%), male babies (53.9% vs 51.4%), BMI of mother (> 24) (8.8% vs 4.8%), cephalopelvic disproportion (21.1% vs 0.9%), intrauterine asphysia (20.3% vs 6.7%), abnormality of force of labor (4.2% vs 2.7%), prolonged labor (2.9% vs 1.0%) and placenta previa (1.4% vs 0.4%). Our study also indicated that the higher the educational level was, the higher the rate of CS appeared; and the older the pregnant women was, the higher the rate of CS was. In CS group, over 70% primipara were over 24 years, and over 20% primipara had cephalopelvic disproportion and over 20% had intrauterine asphysia in CS group.
CONCLUSIONSAt present, the occurrence rate of cesarean section was rather high (45.6%) in China. The high rate of CS was more likely to associate not only with abnormal physiological/medical factors (eg. cephalopelvic disproportion, intrauterine asphysia, abnormality of force of labor, and prolonged labour, etc.), but also with some demographic factors as education, occupation, income and age, etc. It is necessary to take measures to reduce the unnecessary CS in China.

OBJECTIVETo research on the conservative methods used to preserve the femoral head of patients with osteonecrosis of the femoral head.
METHODSIn these series surgical procedures the osteonecrotic lesion was removed and various vascularized bone blocks or periosteal flaps with its nutrient vessels were transferred to regain sphericity of the femoral head and reinforce the sequestrum. The current study assessed 1005 patients (1226 hips) operated on from 1989 to 2002 with an average follow-up of 5.1 years (range, 1.5-15 years). The mean age of the patients was 37.4 years (range, 17-65 years).
RESULTSSixty-one hips (57 patients) had conversion surgery to a total hip arthroplasty because of progressive collapse or severe pain, or both. In the patients without failure, postoperative Harris hip score improved significantly. Of the 1174 reconstructions that were in situ, 1041 (89.4%) were clinically successful, and 878 (75.4%) were radiologically successful. In relation to the stage of necrosis according to the classification system of Ficat and Alert, good results were achieved in 95.3% of the patients with stages II disease, 87.9% with stages III and 60.8% with stages IV.
CONCLUSIONSConservative methods of vascularized bone block or periosteal flap transfer should be considered in active symptomatic patients to preserve the femoral head. In addition, the earlier the stages of the disease the better outcome could be obtained.

OBJECTIVETo determine whether serum homocysteine and folate levels are correlated with the occurrence of neonatal asphyxia and to study the effects of gender and gestational age on serum homocysteine and folate levels.
METHODSThirty-five neonates with mild asphyxia (19 males and 16 females) and 40 normal neonates (control group,18 males and 22 females) were enrolled in this study. The asphyxia and the control groups consisted of 10 and 11 cases of preterm infants respectively. Serum homocysteine levels were measured using ELASA. Serum folate levels were measured using radioimmunity assay.
RESULTSSerum homocysteine level (14.66+/-2.61 micromol/L vs 7.55+/-0.50 mumol/L; P<0.05) was significantly higher and serum folate level (2.47+/-0.24 ng/mL vs 3.28+/-0.28 ng/mL; P<0.05) was significantly lower in the asphyxia group than that in the control group. There were no significant differences in serum levels of homocysteine and folate between males and females either in the asphyxia group or the control group. The asphyxiated neonates born at premature showed increased serum homocysteine level compared with the full-term neonates with asphyxia (21.25+/-5.01 micromol/L vs 12.34+/-2. 01 micromol/L; P<0.05).
CONCLUSIONSThe increased serum homocysteine level and decreased serum folate level are correlated with the occurrence of neonatal asphyxia. Serum homocysteine and folate levels are not associated with the gender. A more significantly increased serum homocysteine level may be found in asphyxiated neonates born at premature.
