Objective To discuss the influence of bath frequency on neonatal skin condition and body temperature. Methods 108 newborns from obstetrics of People′s Hospital of Peking University during November 2015 to December 2015 were selected, and were randomly distributed t into two groups by lottery. The control group took bath every day, whereas the experimental group did every three days. The newborns were followed up for 4 weeks on their skin condition and body temperature. Then the data were systemized and performed statistical analysis. Results During the first 4 weeks after babies were born, the control group and experimental group showed no significant difference on their skin condition (P>0.05). When compared at the time of first 3 days, 1 week and 2 weeks after the babies were born, body temperature of the experimental group were (36.693±0.182), (36.738±0.174), (36.772±0.185)℃, while the control group were (36.591 ± 0.160), (36.671 ± 0.158), (36.684 ± 0.155)℃,which tended to be significantly lower than the experimental group (t values were -2.697,-2.087,-2.669, P <0.01 or 0.05), but still within the normal range. However, this difference of body temperature disappeared after the first 2 weeks (P>0.05). Conclusions Reducing the bath frequency form once a day to every third day showed no influence on neonatal skin condition. Meanwhile, it did avoid significant reduce of body temperature after bath. This may help improve healthy skin care of newborns, promote their growth, and at the same time, redistribute the clinical nursing work efficiently.

Wnt signaling is implicated in the control of cell growth and differentiation during neural stem cell(CNS) development.Wnt3a, one of wnt gene family members, has effect on regeneration neurospheres and differentiation into neurons.Wnt3a inhibits regeneration of neurospheres, and promotes its differentiation. In vitro neurosphere was cultured in a serum-free defined medium DMEM/F12 supplemented with bFGF and EGF. Dissociated cells were plated onto poly-d-lysine-coated coverslips and propagated in medium containing recombined Wnt3a-adenovirus. Plenty of Nurr1 were detected by RT-PCR after 3 days. Wnt3a combined AA would improve NSC differentiation into dopaminergic (DA) neuron. The quantity of DA neuron is obviously more than the AA alone group's. Moreover, the expression of TH mRNA is 1.86 fold in Wnt3a combined AA group. Induced cells were immunostained for TH and DAT. The proportion of TH-positive was (37.42 ? 2.54) % (P

Objective:To establish a risk assessment system focusing on surgical and anesthesian-related indicators for the incidence of complications and mortality of hip fracture surgery in senile patients, and to evaluate its prediction accuracy, sensitivity and specificity.Methods:From January 2020 to February 2021, a total of 1 086 elderly patients (493 males and 593 females) aged 76±5 years (ranging from 60 to 94 years) underwent hip fracture surgery in Tianjin Hospital were collected. A total of 543 patients were randomly selected for the establishment of the hip fracture scoring system in senile patients, including 253 males and 290 females, aged 75±6 years (ranging from 60 to 92 years). With the preoperative physiological factor score and surgical risk factor score as independent variables and the occurrence of complications and death as dependent variables, binary logistic regression analysis was performed to establish a surgical risk scoring system for hip fracture in senile patients. The remaining 543 patients, including 240 males and 303 females, aged 74±7 years (range 60-94 years), their data were used to compare AUC, sensitivity, specificity, and compliance of the physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM), Daping orthopedics operative risk scoring system for senile patient (DORSSSP), and our surgical risk scoring system for hip fracture in senile patients through receiver operating characteristic (ROC) curves, and to compare the predictive value of these systems for complication incidence and mortality.Results:The predictive model equation of the elderly hip fracture scoring system is: ln R1/ (1- R1) =-7.13+0.112× PS+0.148× OS; ln R2/ (1- R2) =-6.14+0.124× PS+0.136× OS; [ R1 is the incidence of complications, R2 is the mortality, PS (physiology score) is the score of preoperative physiological factors, and OS (operation score) is the score of surgical risk factors]. Among the 543 patients whose data were used to compared with the hip fracture scoring system, POSSUM and DORSSSP, 72 actually developed complications and 36 died. The complication rate predicted by surgical risk scoring system for hip fracture in senile patients was 12.05%±6.34% (range 6.18%-61.29%), and 64 cases were predicted to have complications. The predicted mortality was 6.05%±3.26% (range 2.45%-58.36%), and 29 cases were predicted to die. The complication rate predicted by POSSUM was 25.36%±13.95% (range 9.16%-76.34%), and 126 cases were predicted to have complications. The predicted mortality rate was 10.46%±5.31% (range 6.23%-59.34%), and 54 deaths were predicted. The predicted complication rate of DORSSSP was 19.34%±9.67% (range 8.36%-70.85%), and 99 cases were predicted to have complications. The predicted mortality was 10.12%±5.16% (range 7.35%-57.54%), and 52 deaths were predicted. In predicting the incidence of complications, the AUC of surgical risk scoring system for hip fracture in senile patients, POSSUM and DORSSSP were 0.95, 0.82 and 0.75, the sensitivity was 0.89, 0.83 and 0.85, the specificity was 0.80, 0.86 and 0.92, and the compliance rate was 0.94, 0.93 and 0.94, respectively. In the prediction of mortality, the AUC of surgical risk scoring system for hip fracture in senile patients, POSSUM and DORSSSP were 0.87, 0.67 and 0.71, the sensitivity was 0.85, 0.69 and 0.75, the specificity was 0.73, 0.94, 0.95, and the compliance rate was 0.94, 0.93 and 0.94, respectively. Conclusion:Compared with POSSUM and DORSSSP, hip fracture scoring system in elderly patients has improved its ability to predict surgical risk, and can accurately predict the incidence of complications and mortality in elderly patients undergoing hip surgery.
