Objective To determine the optimum dose of Oxycodone for anesthesia induction in patients undergoing laparoscopic cholecystectomy. Methods Ninety patients, ASA Ⅰ or Ⅱ , scheduled for elective LC, were randomly divided into 3 groups using random number table (O 1~O 3 groups, n = 30 each). Anesthesia was induced with iv Propofol 1.00~2.00 mg/kg, Oxycodone 0.20 mg/kg, 0.3 mg/kg and 0.4 mg/kg (O 1~O 3 groups, respectively), and Vecuronium 0.10 mg/kg. Before anesthesia induction ( T0 ), 1 min after Laryngeal Mask intubating ( T1 ), the instant of pneumoperitoneum ( T2 ), separation of the gallbladder ( T3 ), wake up immediately ( T4 ), leaving the recovery room ( T5 ), the heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded. At T4, leaving the recovery room ( T5 ), 4 hours after the operation ( T6 ), 8 hours after operation (T7), the numeric pain rating scale (NRS) were recorded. The overall amount of remifentanil and Oxycodone were record. The wake up time, additional analgetic cases and the adverse reactions were recorded. Results The average HR, SBP and DBP fluctuations in the O 2 and O 3 groups were not more than 20.00% of the basal values. There was no significant difference in wake up time between the three groups. There were 22 cases of patients, the NRS> 4, in O1 group requires additional analgesics after they wake up, more than O 2 and O 3 group (7, 3 respectively, P < 0.05). The overall Oxycodone consumption of the three groups were O1: (18.93 ± 4.34) mg (0.90~2.60 mg),O2: (25.50 ± 4.49) mg (1.40~3.00 mg), O3: (26.10 ± 4.55) mg (1.80~3.40 mg) (F = 23.79, P = 0.000). There was no significant difference in adverse reactions between the three groups, but one patient had respiratory depression in O3 group. Conclusion The optimum dose of Oxycodone for anesthesia inducing in laparoscopic cholecystectomy were 0.30 mg/kg.

Objective To investigate training effects of Shandong oncology specialist nurses. Methods A self-designed questionnaire about training effects was used to investigate 149 oncology specialist nurses in 48 hospitals in Shandong province. Results The total score of training effects was 202.075 ± 17.918. Differences were significant in human relations of training effects of oncology specialist nurses (F=3.439,P<0.05 ). 94.74％(126/133)of the oncology specialist nurses had no changeable in their work after training, 62.41％(83/133)served as skeleton staffs, only 22.56％(30/133)published in journals, 58.65％(78/133)of the specialist nurses had no chance to attend meeting and only 3.01％(4/133)had experiences to study for a month or more. Conclusions The training effects of Shandong oncology specialist nurses some abilities still need to be increased, the training contents need to be enriched, the use and management of the specialist nurses need to be further regulated, and the development of the oncology specialist nurses need to be further improved.

OBJECTIVESince 1986, the reference of birth weight for gestational age has not been updated. The aim of this study was to set up Chinese neonatal network to investigate the current situation of birth weight in China, especially preterm birth weight, to develop the new reference for birth weight for gestational age and birth weight curve.

METHODA nationwide neonatology network was established in China. This survey was carried out in 63 hospitals of 23 provinces, municipalities and autonomous regions. We continuously collected the information of live births in participating hospitals during the study period of 2011-2014. Data describing birth weight and gestational age were collected prospectively. Newborn's birth weight was measured by electronic scale within 2 hours after birth when baby was undressed. The evaluation of gestational age was based on the combination of mother's last menstrual period, ultrasound in first trimester and gestational age estimation by gestational age scoring system.

STATISTICAL ANALYSISthe growth curve was drawn by using LMSP method, which was conducted in GAMLSS 1.9-4 software package in R software 2.11.1.

RESULTA total of 159 334 newborn infants were enrolled in this study. There were 84 447 male and 74 907 female. The mean birth weight was (3 232 ± 555) g, the mean birth weight of male newborn was (3 271 ± 576) g, the mean weight of female newborn was (3 188 ± 528) g. The test of the variables' distribution suggested that the distribution of gestational age and birth weight did not fit the normal distribution, the optimal distribution for them was BCT distribution. The Q-Q plot test and worm plot test suggested that this curve fitted the distribution optimally. The male and female neonatal birth weight curve was developed using the same method.

CONCLUSIONUsing GAMLSS method to establish nationwide neonatal birth weight curve, and the first time to update the birth weight reference in recent 28 years.
