As a local medical college,taking the school running orientation and characteristic into consideration,our school paid attention to people-oriented policy,optimizing the course structure,strengthening practice teaching in the revised talent cultivation scheme and constructed talent cultivation system which was in line with international norms and had local distinguishing feature.

To establish a fetal biparietal diameter (BPD)-gestational age formula based on the data of pregnant women from Xiaoshan District of Hangzhou, and to evaluate its application in prenatal screening.Data of 3500 pregnant women with gestational age between 15 weeks and 19 weeks+6 receiving prenatal screening in Xiaoshan Hospital during May 2014 and May 2015 were collected. BPDs were used to establish a localized BPD-gestational age formula. The localized formula was used to evaluate the prenatal screening risks in 1759 pregnant women with irregular menstrual cycles or uncertain last menstrual period (LMP) in Xiaoshan District, and the results were compared with those calculated using formula in LifeCycle 4.0.With localized formula, the total positive rate of Down syndrome, trisomy 18 syndrome and deformity of neural tube was decreased from 6.96% to 5.85% (<0.05), in which the positive rate of Down syndrome decreased (<0.05), that of deformity of neural tube increased (<0.05), and that of trisomy 18 syndrome remained the same (>0.05). The median MoMs of free-hCG β and α-fetoprotein calculated using localized formula were significantly different from those calculated using the formula in LifeCycle 4.0 (all<0.05), and the former ones were more closer to 1. For women of fetus diagnosed with the above diseases, the positive rate calculated using localized formula was almost the same as that calculated using the formula in LifeCycle 4.0.BPD-gestational age formula should be localized based on the statistical analysis of the local population, which will help to reduce the false positive rate, and make the results more accurate and reliable in prenatal screening.

Objective:To evaluate the effects of opioid-sparing analgesia on the incidence of sepsis in severely burned patients in the retrospective cohort study.Methods:The clinical data from patients with severe burns admitted to three teaching hospitals in Guangdong from 2011 to 2020 were retrospectively extracted and analyzed. The patients were divided into 2 groups based on the analgesic regimen within 30 days after injury: continuous opioids analgesia group (continuous opioid infusion at a relative constant rate for more than 72 h) and opioid-sparing analgesia group (patient-controlled intravenous analgesia/intermittent administration/opioid-free analgesia). Patient′s age, severity of burn, inhalation injury and basal pain score at rest were matched by the propensity score at a 1∶1 ratio. The primary outcome measure was the occurrence of sepsis within 90 days of admission. Secondary outcome measures included 30-day and 90-day all-cause mortality, clinical diagnosis of multiple organ dysfunction syndrome, and prevalence of burn wound infection. The amount of opioid used was also recorded.Results:A total of 328 severely burned patients were finally enrolled, with 145 patients in continuous opioid analgesia group and 183 patients in opioid-sparing analgesia group, and 110 pairs of patients (220 cases) were finally matched by the propensity score.Compared with continuous opioid analgesia group, the total consumption of opioid, daily consumption per analgesia, and consumption per burn area were significantly decreased, and the incidence of sepsis and wound infection was decreased( P<0.05), and no significant change was found in the incidence of multiple organ dysfunction syndrome, 30-day and 90-day all-cause mortality in opioid-sparing analgesia group( P>0.05). Conclusions:Compared with the continuous opioid analgesia regimen, opioid-sparing analgesia can reduce the risk of sepsis in severely burned patients.
