Objective To discuss the safety and efficacy of inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture.Methods There was an retrospective analysis on operation videos and clinical data for 16 participants of inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture with the period from March in 2012 to September in 2015. And these were statistically analyzed including the operation time, intraoperative bleeding volume, postoperative drainage volume, removal time of drainage tube, admission time after operation and the incidence of postoperative complications of vesicoureteric reflux and stenosis.Results The operations of 16 participants were completed successfully without converting to open surgery. The operation time was 60 ~ 125 min (Mean time: 85 min); intraoperative bleeding volume was 20 ~ 50 ml (Mean volume: 32 ml); postoperative drainage volume was 60 ~ 400 ml (Mean volume: 106 ml); removal time of drainage tube was 3 ~ 6 d (Mean time: 4.2 d) and admission time after operation was 7 ~ 10 d (Mean time: 8.5 d). There was the follow-up with 6 ~ 18 months (Mean time: 12 months) for participants. No anastomotic stenosis was present. In addition, one participant was suffered from mild vesicoureteric relfux. And there was no aggravation during 18 months.Conclusions The inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture was safe and effective. It was found that the operation time was significantly shortened and the incidence of postoperative complications of vesicoureteric relfux and anastomotic stenosis was not increased. By contrast, the six-stitch suture could reduce the incidence of anastomotic stenosis.

OBJECTIVETo investigate the effect of exchange of tracheal tube for a laryngeal mask airway (LMA) on intratracheal extubation stress response under deep anesthesia level after surgery in elderly patients with hypertension.
METHODSFrom October 2008 to June 2009, 40 hypertension patients aged from 65 to 78 years scheduled for upper abdominal surgery were randomly divided into 2 groups, one was extubated intratracheal tube when being awake (group TT, n = 20) and the other was extubated and exchanged for LMA under deep anesthesia (group LM, n = 20). The American Society of Anesthesiologists (ASA) of the patients were I o rII. The data of mean arterial pressure (MAP), heart rate(HR), pulse oxygen saturation (SPO(2)), end-tidal carbon dioxide tension (P(ET)CO(2)) and rate pressure product(RPP) were recorded before induction of anesthesia (T(0)), suction (T(1)) and at 0 (T(2)), 5(T(3)), and 10 (T(4)) and 15 min (T(5)) after extubation tracheal tube or LMA in two groups. The indices mentioned above also were recorded before and after extubation in group LM. Blood samples were taken at T(0), skin incision, T(2), T(3), for determination of serum concentrations of blood glucose and cortisol. The airway adverse events in the recovery period were recorded.
RESULTSCompared with group LM, MAP, HR and RPP were significantly higher at T(1), T(2), T(3) than T(0) in group TT (P < 0.05). There was no significant difference in the indices mentioned above during extubated intratracheal tube and exchanged for LMA under deep anesthesia in group LM (P > 0.05). The incidence rate of glossoptosis in group TT was significantly higher than those in group LM (P < 0.01), while complications, such as cough, bucking, breath holding during the recovery stage in group TT were more than those in group LM (P < 0.05). Compared with the baseline value, blood glucose and cortisol concentration level were significantly increased in group TT than in group LM (P < 0.01).
CONCLUSIONSExchange of tracheal tube for LMA under deep anesthesia during recovery stage can decrease the stress response during the recovery stage and attenuate the harmful response of respiratory tract. It is suitable for the elderly patients with hypertension.

Objective:
To investigate neglect among preschool children in two-child families in southwest Shandong Province, and to provide reference is for improving nursing parenting quality of two-child families.
Methods:
A questionnaire survey was conducted among 2 646 parents of two-child families and 2 074 parents of one-child families from 16 kindergartens in southwest Shandong Province.
Results:
The total neglect rate of two-child family preschool children in southwest Shandong Province was 27.37%, and the degree score of neglect was(40.15±5.51). The physical neglect rate(10.39%), emotional neglect rate(40.15±5.51), total neglect (38.15±4.88) and emotional neglect (46.12±6.91) of boys were higher than those of girls, and the difference was statistically significant(χ2/t=4.57, 6.65, 4.58, 4.72, P<0.05); No significant frequencies were found in total neglect rate, total neglect, neglect rate and neglect at all levels among all age groups(P>0.05); Among preschool children with siblings aged 7-<13, ≥13, total neglect rate(30.44%, 32.77%), emotional neglect rate(10.20%,12.00%), total neglect degree (44.71±5.98, 45.33±5.20) and emotional neglect degree (45.95±7.12, 48.86±4.97) of preschool children in two-child families have higher than those in onechild families, and the differences were of statistical significance(χ2/t=31.10, 4.55, 27.92, 24.13, 19.83, P<0.05); the total neglect rate(27.37%), emotional neglect rate(23.47%), emotional neglect (43.68±6.83) of twochild families and the total neglect (40.15±5.51) were higher than those of one-child families, and the differences were of statistical significance(χ2/t=4.98, 4.96, 3.76, 8.53, P<0.05). The age of siblings(OR=0.58), the education level of mothers(OR=0.64), and the main executor of family education (OR=1.54) were main factors to influence the child neglect of preschool children in two-child families(P<0.05).
Conclusion
Neglect of preschool children in two-child families is higher than that in one-child families in southwest Shandong, especially among those preschool boys and preschool children whose siblings were of school age.

PURPOSE: Triple-negative breast carcinoma (TNBC) is accompanied with high risk of metastasis and recurrence. The present study aimed to explore the clinicopathological and prognostic roles of putative tumor-related genes in patients with TNBC. METHODS: Thirty pairs of frozen-thawed tumors were used to select reliable indicators via real-time quantitative polymerase chain reaction (RT-qPCR). Then, 150 pathology specimens were used to evaluate the expression of proteins in TNBC through immunohistochemistry. In addition, Kaplan-Meier curves and Cox regression analysis were also performed to analyze the overall survival and disease-free survival. RESULTS: RT-qPCR results indicated that among all the proteins analyzed using fresh-frozen TNBC samples, the expression levels of only Survivin and zinc finger of the cerebellum 1 (ZIC1) were obviously different from those in the corresponding normal tissues. Survivin and ZIC1 expression had opposite effects on the clinicopathological diagnosis and prognostic assessment in TNBC patients. Further, there was a negative correlation between Survivin and ZIC1 expression. In addition, the “Survivin-positive ZIC1-negative group” was associated with histologic grade, lymph node metastasis, and TNM staging (p < 0.001) and this was also an independent factor for evaluating the prognosis of TNBC in patients. CONCLUSION: In summary, the expression levels of Survivin and ZIC1 in TNBC are different from those in normal tissues and are negatively correlated mutually. The combined detection of Survivin and ZIC1 expression levels could allow better comprehensive diagnosis and prognostic evaluation for TNBC patients.
