Objective:To explore the effect of continuous obstetric-pediatric cooperative nursing on anxiety, depression and the parenting sense of competence in NICU premature mothers.Methods:Totally 140 mothers of NICU preterm infants in hospital from January 2018 to December 2018 were selected and randomly divided into the control group and intervention group according to the method of random number table, and each group 70 cases. The control group received the routine nursing mode in obstetrics and paediatrics and the intervention group received the continuous obstetric-pediatric cooperative nursing based on routine nursing. To compare the anxiety level, depression level, the score of parenting sense of competence, hospitalization days of preterm infants, the outpatient rate and the readmission rate of preterm infants within 1 months of discharge between two groups.Results:The levels of anxiety and depression of the mothers of premature infants in the intervention group during hospitalization ,1 week after discharge and 1 month after discharge were (43.17±6.89), (8.96±2.67), (34.65±6.87), (7.65±1.92), (34.97±6.06), (6.29±1.54) points, lower than control group (47.03±8.06), (10.97±3.34), (45.44±7.72), (9.43±2.61), (41.46±7.26), (8.28±2.23) points, the differences between the two groups showed statistical significance ( t value was 2.331-6.097, P<0.05). The two dimensions of parenting efficacy and parenting satisfaction were (31.47±4.97), (43.38±4.21) points, which were higher than (25.91±5.42), (39.43±5.91) points of the control group, there were significant statistical differences among the two groups ( t value was -6.314 and -4.528, P<0.01). The hospitalization days of premature infants, outpatient and readmission rate within 1 month of discharge were (13.25±3.27) days, 8.57% (6/70), 2.86% (2/70), which were shorter or lower than (15.59±2.79) days, 24.29% (17/70), 12.86% (9/70) in the control group, the differences were statistically significant ( t value was 2.909, χ2 values were 6.295, 4.834, P<0.05). There were significant statistical differences among interaction effect, time effect and intergroup effect ( F values were 4.921-99.310, P<0.05). Conclusion:Obstetrical-pediatric cooperative nursing can effectively to lower the anxiety and depression level of preterm mothers, improve the parental competence, promote the mental health of preterm mothers, and ultimately shorten hospital days and decrease the rate of outpatient and readmission of premature infants, which is conducive to preterm infants′ rehabilitation.

Objective To assess the therapeutic effects of activated charcoal on the acute dichlorvos poisoning in rats. Method Thirty male clean grade Wistar rats were randomly (random number) divided into three groups: control group (group A, n = 10), single dose activated charcoal group (group B, n = 10) and multi-dose activated charcoal (group C, n=10). The rats of group A were suffered from 35 mg/kg dichlorvos exposure by oral without activated charcoal and senna. The rats of group B received 35 mg/kg dichlorvos exposure by oral with 175 mg/kg activated charcoal given immediately after dichlorvos exposure and 35 mg/kg senna given half an hour later. In the group C, 35 mg/kg dichlorvos was given to rats by oral with 175 mg/kg activated charcoal given immediately after dichlorvos exposure and 35 mg/kg senna given half an hour later and then every four hours. Blood samples were collected from the carotid artery at different intervals after exposure. DDVP concentration and total blood acetyl-cholinesterase activity were detected. Differences in serum DDVP concentration, Cmax, AUC (0→∞ ), MRT and acetylcholinesterase among three groups were calculated by using ANOVA. Results Serum DDVP levels in single dose group and in multi-dose group were significantly different from those in control group (P < 0.05). The DDVP levels in multi-dose group were significantly different from those in single dose group 4 hours after exposure (P < 0.05). The AUC and Cmax in activated charcoal treatment groups were significantly different from those in control group (P < 0.05). There were no significant differences in MRT among three groups. Fours hours after exposure to dichlorvos,the levels of serum acetylcholinesterase in rats of group B and group C were significantly different from that in rats of group A (P < 0.05), and there was no significant difference in acetylcholinesteras between group B and group C (P > 0.05). Another four hours later, no differences in acetylcholinesterase were found a-mong three groups (P > 0.05). Conclusions The peak concentrations of dichlorvos in blood are lower in group B and group C, and the blood acetylcholinesterase inhibition is quelled by activated charcoal. Therefore, the effects of multi - dose of activated charcoal is better than that of single dose of activated charcoal.

Background and purpose:A variety of measures are taken preoperatively to reduce the tumor size of stageⅠb2 bulky cervical cancer before surgery. Which one is safer and more effective, currently, there is no consensus. This article compared the effect in 3 different treatment methods (neoadjuvant chemotherapy, neoadjuvant chemoradiotherapy and operation) on patients with stageⅠb2 bulky cervical cancer, and provided evidence for clinical decision. Methods:Retrospective analysis the clinical date of 133Ⅰb2 bulky cervical cancer patients, who received preoperative neoadjuvant chemotherapy, neoadjuvant chemoradiotherapy and direct operation from Apr. 2006 to Oct. 2010 in our hospital. Results: The effective rates of neoadjuvant chemotherapy, neoadjuvant chemoradiotherapy group were 91.8% and 92.5%, respectively, there was no statistical difference(P>0.05). The tumor size got smaller after treatment compared with the size before treatment (P<0.05);The pathological efifciency rates were 95.56%and 97.30%, respectively, the difference was not statistically significant (P>0.05). The bleeding volume of neoadjuvant chemo radio therapy group was significantly higher than those in the other 2 groups (158.9±50.7 vs 116.8±45.5, 123.1±30.2;P<0.05), the infection of immediate surgery group was more severe than the other 2 groups (P<0.05). The pairwise comparison of average operation time in neoadjuvant chemotherapy group, neoadjuvant chemoradiotherapy group, and the immediate surgery group, pairwise comparisons of neoadjuvant chemotherapy group and the immediate surgery group in bleeding, comparion of neoadjuvant chemotherapy group and neoadjuvant chemoradiotherapy group on postoperative infection, and the comparison of the 3 groups on pelvic organ injury and lymphocele, had no statistical difference(P>0.05);Pathological examination showed that vascular invasion in surgery group had statistical differences than other 2 groups (P<0.05), there was no patient with positive margin in the 3 groups, and the lymph node metastasis rates also had no statistical difference (P>0.05);Besides, there were no statistical difference on vascular invasion between the 3 groups (P>0.05);And on 3-year overall survival, disease-free survival there was no statistical difference between the 3 groups (P>0.05). Conclusion:Neoadjuvant chemotherapy can effectively reduce tumor size for patients with stage Ⅰb2 bulky cervical cancer before operation, it is better than direct surgery or preoperative chemoradiotherapy in improving the resection rate, and reducing postoperative pathological positive rate, and infection. Neoadjuvant chemotherapy can improve the pathological complete remission rate. The combination of radiation and chemotherapy might produce synergistic effect on huge cervical tumor, but it can’t improve the survival rate. Therefore, neoadjuvant chemotherapy is the best choice for the stageⅠb2 cervical cancer patients. Therefore, a long-term follow-up or large sample randomized controlled trials is necessary to assess the prognosis of preoperative neoadjuvant chemotherapy and neoadjuvant chemoradiotherapy.

Objective:
To evaluate the effect of functional training on the improvement of Cobb Angle, ATR and quality of life in adolescent idiopathic scoliosis.
Methods:
Database of CNKI, WanFang, WeiPu, Web of Science, PubMed were reconnoitered for the purpose of research articles of Interest. Literature was screened according to the inclusion criteria, randomized controlled trials (RCTS) were collected and Cochrane risk bias assessment methodology quality was used, and Revman 5.3 software was used to conduct combined effector subgroup analysis on outcome indicators (Cobb Angle, ATR, SRS-22 patient questionnaire).
Results:
A total of 10 RCT (398 AIS patients) were included in the study. There were two high , five moderate and three low quality studies, respectively. Compared with other non operative treatments, functional training could reduce Cobb horn in patients, MD = -6.56 (95% CI =-7.30--5.83, P <0.01, I 2=0). Further subgroup analysis showed that there were no statistically significant differences in effect size between the subgroups of Cobb Angle, age, intervention period and control method at the time of inclusion ( P >0.05). Compared with the non intervention blank group, the functional training group could reduce the Cobb Angle of patients ( MD = -5.25 , 95% CI =-8.27- -2.98 , P < 0.01 ), with high heterogeneity ( I 2=61%). Effect on angle of trunk rotation(ATR):functional training group could reduce patients ATR, MD =-1.91 (95% CI =-2.25--1.57, P <0.01, I 2=0). The impact on the quality of life:functional training of patients with SRS-22 questionnaire function, pain had no statistical significance ( P >0.05), and self image ( MD =0.64, 95% CI =0.53- 0.75 , P <0.01), mental health ( MD =0.44, 95% CI =0.15-0.74, P <0.01), satisfaction ( MD = 0.58 , 95% CI =0.11- 1.06 , P = 0.02 ) were statistically significant.
Conclusion
Functional training can not only reduce the Cobb Angle and ATR of AIS patients, but also improve the quality of life in terms of self image, mental health and satisfaction of the patients. However, due to heterogeneity and bias, more high quality studies are needed to verify.

OBJECTIVE:To observe the efficacy and safety of doxofylline combined with ceftazidime in the treatment of elder-ly patients with chronic emphysema. METHODS:Data of 78 elderly patients with ceftazidime was collected and divided into single drug group(31 cases)and combined medication group(47 cases)according to different treatment methods. All patients adopted flu-id infusion,oxygen inhalation and nutrition support. Based on it,single drug group received 0.05 g Doxofylline injection,once ev-ery 12 h. Combined medication group additionally received 1.0 g Ceftazidime for injection,once every 12 h. If the symptoms were out of control,20 mg prednisone was given,twice a day. The courses of 2 groups were 10 d. Total efficacy,pulmonary functions [maximum mid-expiratory flow(MMEF),1s forced expiratory volume percent predicted(FEV1%),peak expiratory flow(PEF)] before and after treatment,American Concise Health Survey Questionnaire(SF-36 scale)(QLS)and the incidence of adverse reac-tions in 2 groups were observed. RESULTS:The total effective rate in combined medication group was significantly higher than sin-gle drug group,the difference was statistically significant (P<0.05). Before treatment,there was no significant difference in MMEF,FEV1%,PEF and QLS scores between 2 groups(P>0.05). After treatment,MMEF,FEV1%,PEF and QLS scores in 2 groups were significantly higher than before,and combined medication group MMEF,FEV1%、PEF were higher than single drug group,the difference was statistically significant (P<0.05),but there was no significant difference QLS scores in 2 groups(P>0.05). And there was no significant difference in the incidence of adverse reactions in 2 groups (P>0.05). CONCLUSIONS:Based on conventional treatment,doxofylline combined with ceftazidime shows better efficacy than doxofylline alone in the treat-ment of elderly patients with chronic emphysema,it can improve pulmonary functions,with better safety.

Objective To investigate the expression of regulators of G protein signaling(RGS), including RGS2, RGS3 and RGS4 in OLETF rats, as well as the effects of metformin on these expressions. Methods LETO rats were used as control group. Eight-week-old male OLETF rats were assigned to two guoups randomly:model and trial(metfomin dose during 8~(th) to 22~(nd) weeks:300mg kg~(-1)·d~(-1);during 23rd to 28th weeks:400 mg·kg~(-1) ·d~(-1))groups. Expressions of RGS mRNA in aorta and heart werequantified by real-time PCR. Results RGS2, RGS3 and RGS4 mRNA of the thoracic aorta and left ventricle were significantly higher in model group than in control group (P<0.01). Compared with model group, metformin significantly reduced their mRNA in trial group (P<0.01). Conclusions Upregulation of RGS2, RGS3 and RGS4 mRNA expression in the thoracic aorta and left ventricle of OLETF rats is in correlation with cardiovascular lesions; while downregulation of their expression is in correlation with the action of metformin.
