Objective To find out the requirement and to evaluate the effect of post-abortion counseling and education (PACE) among unmarried abortion adolescents.Methods The subjects of the study were unmarried adolescents from 10 to 24 years of age who wanted induced abortion in the Second Affiliated Hospital of Sun Yat-sen University from December 2007 to April 2008.Totally 122 subjects received the intervention of PACE were considered as intervention group.Meanwhile,67 subjects refused the intervention of PACE were considered as no intervention group.Two groups were both investigated the requirements of PACE before abortion and were followed-up at one year after abortion.Results 97.4% (184/189) of 189 unmarried abortion adolescents were willing to receive PACE,48.1% (91/189) of them hoped to receive PACE when saw the doctor,72.0% (136/189) of them required face-to-face counseling during PACE.During the year after abortion,74% (57/77) cases in intervention group and 24% (10/41) cases in no intervention group took effective contraception (P< 0.01 ),while 1% (1/77) of intervention group and 10% (4/41) of no intervention group had unwanted pregnancy.There were significant different for the rate of unwanted pregnancy between two groups (P=0.034).Conclusion For unmarried abortion adolescents,the intervention of PACE may markedly increase the rate of effective contraception used and decrease the rate of another unwanted pregnancy.

OBJECTIVETo detect the human papillomavirus (HPV) infectious condition in women with abnormal cytology and evaluate its values in the screening of high grade cervical intraepithelial lesion.

METHOD101 patients who underwent thinprep cell test(TCT) with abnormal cervical cytology were selected to undergo HPV test, all subjects also received tissue biopsy at the same time.

RESULTS(1) Among the 101 patients,the incidence rates of high risk HPV infection of those with ASCUS, LSIL, HSIL and squamous cell carcinoma were 84.2%, 88.6%, 100.0% and 2/2 respectively. (2) Among the patients with abnormal cytology,the number of patients with pathologically confirmed results of CIN I and CIN II or worse were 20 and 81, the incidence rates of high risk HPV infection of those with CIN I and CIN II or worse were 60.0% and 97.5% respectively. (3) In the ASCUS group, the incidence rates of CIN II or worse with high risk HPV infection were 87.5% and the incidence rates of CIN II or worse without high risk HPV infection were 16.7%. (4) The prevalence of high risk HPV types from highest to lowest order were follow: HPV16 (39.6%), 58 (17.8%), 52 (16.8%), 18 (9.9%), 33 (9.9%).

CONCLUSIONSThe infection rate of high risk HPV was positively correlated with the levels of cervical lesions. HPV test is a good triage approach for the patients with ASCUS. HPV16, 58, 52, 18, 33 are the most common in the patients of cervical lesions.

Objective:To explore the risk factors associated with a three-month prognosis in patients with aortic acute cerebral infarction.Methods:A prospective study was conducted on 191 patients with aorthropathic acute cerebral infarction included in the Department of Neurology from June 2018 to December 2019, and the patients were divided into good prognosis group (153 cases) and poor prognosis group (38 cases) according to the MRS score of the patient's 3-month prognosis, and the general data, past medical history and blood pressure variability evaluation index (BPV) between the two groups were correlated analysis. The t-test was used to compare the measurement data with normal distribution, the χ 2 test was used to compare the counting data, and the Logistic regression analysis was used to analyze the risk factors. Results:The proportion of patients with diabetes history in the poor prognosis group (20.3% (31/153)), admission NIHSS score ((3.03±2.01) points), standard deviation (SD) ((12.06±4.46) mmHg) and coefficient of variation (CV) ((8.61±3.08)%) of systolic blood pressure at 24 h were lower than those in the good prognosis group (47.4% (18/38), (5.61±3.84) points, (14.75±3.46) mmHg, (10.41±2.18)%), the differences were statistically significant (the statistical values were χ 2=11.73, t=4.01, t=3.46, t=3.38; P values were 0.001, <0.001, 0.001, and 0.001, respectively). Because 24 h systolic blood pressure SD and 24 h systolic blood pressure CV had obvious collinearity, they were respectively included in the Logistic regression model. Taking diabetes history, NIHSS score and 24 h systolic blood pressure SD into the variables, the multivariate Logistic regression results of adverse prognostic risk factors in patients with acute cerebral infarction showed that the history of diabetes mellitus ( OR=3.649, 95% CI: 1.545-8.648, P=0.003), NIHSS score ( OR=1.472, 95% CI: 1.247-1.725, P<0.001) and 24 h systolic blood pressure SD ( OR=1.201, 95% CI: 1.085-1.336, P<0.001). Taking diabetes history, NIHSS score and 24 h systolic blood pressure CV into consideration, multivariate Logistic regression results of adverse prognostic risk factors in patients with acute cerebral infarction showed that the history of diabetes mellitus ( OR=4.695, 95% CI: 1.873-11.766, P=0.001), admission NIHSS score ( OR=1.922, 95% CI: 1.513-2.441, P<0.001) and 24 h systolic blood pressure CV ( OR=1.220, 95% CI: 1.045-1.425, P=0.012). All are independent risk factors influencing the prognosis of patients. Conclusion:The effect of 24 h systolic blood pressure SD and 24 h systolic blood pressure CV on patient prognosis was more valuable in clinical prediction, and the prognosis value of controlling blood glucose levels in patients with diabetes was higher in patients with cerebral infarction.

[Objective]To explore the effects of family cohesion and child-teacher dependency on children's attention-deficit/hy?peractivity behaviors at one year after their kindergarten entry.[Methods]Based on a cohort of 7465 first-year preschoolers in Long?hua district of Shenzhen in 2014,the information about social-demographic characteristics,family cohesion(assessed with Family Environment Scale-Chinese Version)were collected from their primary-caregivers at kindergarten entry. The teacher rating scores of child-teacher dependency(assessed with Student-Teacher Relationship Scale)and parental rating scores of attention-deficit/hyperac?tivity behaviors(assessed with Conners'Parent Symptom Questionnaire)were examined at one year after their kindergarten entry. Lo?gistic regression were performed to analyze the relationship and interaction between family cohesion and child-teacher dependency in attention-deficit/hyperactivity behaviors,after adjusting for potential confounders.[Results]Children's attention-deficit/hyperactivity behaviors at one year after kindergarten entry were negatively associated with family cohesion (OR=0.85,95% CI=0.75~0.97,P=0.01),but were not significantly associated with child-teacher dependency(OR=1.00,95%CI=0.93~1.08,P=0.98). Furthermore, family cohesion moderated the impact of child-teacher dependency on children ' s attention-deficit/hyperactivity behaviors at one year after kindergarten entry(OR=0.96,95% CI=0.92~0.99,P=0.03). In addition,neither family cohesion(OR=1.08,95%CI=0.88~1.34,P=0.47)nor child-teacher dependency(OR=1.03,95%CI=0.93~1.15,P=0.53)could protect preschoolers from persistence of attention-deficit/hyperactivity behaviors in the first year of kindergarten.[Conclusion]The association of child-teacher dependency and onset of attention-deficit/hyperactivity behaviors is modified by the level of family cohesion in preschool children.

Objective To investigate the effect of Berberine on insulin resistance and its mechanism in Otsuka Long-Evans Tokushima Fatty(OLETF) rats with metabolic syndrome(MS).Methods LETO(Long-evans Tokushima Otsuka)rats(the control group receiving standard normal diet,n=10)and diabetic OLETF rats(the MS group receiving high-fat diet for 24 weeks,n=30).Rats in the MS group were randomly divided into 3 subgroups(n=10,each subgroup).Each subgroup was gavaged with normal saline,high-dose Berberine(100 mg · kg-1 · d-1)and low-dose Berberine (50 mg · kg-1 · d-1) respectively,and the high-fat diet remained unchanged.After 6 weeks of berberine treatment,body weight,blood glucose and lipid metabolism parameters were determined.The oral glucose tolerance test(OGTT) and insulin tolerance test(ITT) were used to detect insulin resistance.Expression levels of the protein and mRNA of 78 kDa glucose-regulated protein (GRP7 8),Caspase-12 and CCAAT/enhancer-binding protein(C/EBP) homologous protein(CHOP) in skeletal muscles were detected by Western blot and RT-PCR.Results After Berberine treatment,the body weight,fasting plasma glucose,fasting insulin[(28.9 ± 2.0) mU/L,(31.5± 2.4) mU/L vs.(36.9 ± 4.7) mU/L],total cholesterol,triglycerides,and low-density lipoprotein cholesterol were decreased,while the high-density lipoprotein cholesterol(HDL-C) levels were increased in MS rats with high-dose berberine and low-dose berberine as compared with the control group (P ＜ 0.05) respectively.Berberine treatment could reduce the protein and mRNA expression levels of GRP78,Capase-12 and CHOP in the skeletal muscle of MS rats(P＜0.05).Conclusions Berberine may alleviate insulin resistance in rats with metabolic syndrome by reducing endoplasmic reticulum stress in skeletal muscle.

OBJECTIVETo study molecular epidemiology of Rotavirus among children under 5 years of age in china.

METHODSStool specimens were collected from 4047 inpatients under 5 years of age with diarrhea in our 9 hospital-based surveillance sites from January 2006 to December 2007 following the WHO Rotavirus surveillance protocol. Rotavirus were detected by ELISA, Further strain characterization of rotavirus was carried out with RT-PCR.

RESULTSA total of 4047 stool samples were collected and 3862 of total stools were tested among which 1700 was positive. The Rotavirus positive rate is 44.0%. A peak admission of rotavirus diarrhea was observed from November to next January. More than 95.4% of viral diarrhea patients occurred in their first 2 years. The incidence rates of rotavirus diarrhea were highest in 12-17 months of age. The most common rotavirus strain was P[8]G3(58.3%); followed by P[8] G1(22.1%), P[4]G1 (3.0%), P[8]G9 (2.4%). G4 was not detected in this study. The four common strains were 80.8% in the world.

CONCLUSIONRotavirus diarrhea was an important infectious disease among children under 5 years of age in China. Safe and effective rotavirus vaccines for the prevention of rotavirus diarrhea and reduction of treatment costs are of significant importance to China.

OBJECTIVE: To investigate the etiology and risk factors for unintentional injuries in children admitted to the pediatric intensive care unit (PICU), and to provide a basis for preventing these injuries and decreasing the mortality rate. METHODS: A retrospective analysis was performed on the clinical data of children with unintentional injuries admitted to the PICU from December 2012 to December 2017. RESULTS: A total of 102 children with unintentional injuries were admitted to the PICU, which accounted for 3.30% (102/3 087) of the overall PICU patients. The top three causes of unintentional injuries were food or drug poisoning, drowning, and foreign body ingestion and aspiration. The proportion of unintentional injuries in boys was significantly higher than in girls (P<0.05). The younger children had a significantly higher proportion of unintentional injuries (P<0.05). The cause of unintentional injuries was also related to age, and the common causes of unintentional injuries varied between different age groups. The proportion of unintentional injuries was not significantly different between children from urban and rural areas (P>0.05). The logistic regression analysis showed that the number of organs with dysfunction after unintentional injuries, especially respiratory, cardiac, neurological, renal and hematological involvement, was closely associated with the mortality rate of children with unintentional injuries (P<0.05); however, it is not an independent risk factor (P>0.05). CONCLUSIONS Prevention is the key to decreasing the incidence of childhood unintentional injuries. Preventive measures should be taken based on patient's sex and age and the cause of unintentional injuries. The spread of first aid knowledge, improvement in emergency transportation, and more attention to organ protection may be useful for decreasing the mortality rate of children with unintentional injuries.

The total score of satisfaction was (66.82 ± 2.26) points in the experimental group and (62.05 ± 2.29) points in the control group, the difference was statistically significant ( t=6. 87, P<0.05). There was no significant difference in the learning and growth of the trainees before and after the training between the two groups ( P>0.05). Conclusions:Using OSCE assessment mode to carry out neurosurgery specialist nurse training is helpful to improve students′ professional skills, critical and difficult medical record management, professional quality, and improve students′ satisfaction with the training.

Objective:To retrieve, evaluate and integrate the evidence related to the preparation process for initiating extracorporeal cardiopulmonary resuscitation in hospital, so as to provide reference for clinical implementation of extracorporeal cardiopulmonary resuscitation.Methods:According to the evidence-based nursing method and the 6S evidence model, guidelines, clinical decisions, expert consensus, systematic review and other literatures related to the preparation process for initiating extracorporeal cardiopulmonary resuscitation in hospital were searched from National Guideline Clearinghouse, Scottish Intercollegiate Guidelines Network, National Institute for Health and Care Excellence, and other websites, UpToDate, The Cochrane Library, PubMed, Embase, CNKI, Wanfang and other databases. The retrieval date limit was from the establishment of the database to May 20, 2023. Researchers assessed the quality of the included articles, and extracted and summarized the evidence that met the quality standards.Results:A total of 11 articles were included, including 2 guidelines, 6 expert consensuses, 1 systematic review and 2 quasi-experimental studies. A total of 18 pieces of evidences were summarized from 6 aspects, including medical conditions, team building, materials management, operation mechanism, pre-initiating treatment and initiating judgment.Conclusions:This study summarizes the evidence of preparation process for initiating extracorporeal cardiopulmonary resuscitation in hospital, which can provide reference for promoting the implementation of extracorporeal cardiopulmonary resuscitation. Future studies still need to focus on team building, personnel training and assessment, and optimisation of the management system, so as to improve the efficiency and readiness of treatment.

Traditional microtubule inhibitors fail to significantly enhance the effect of colorectal cancer;hence,new and efficient strategies are necessary.In this study,a supramolecular nanoreactor(DOC@TA-Fe3+)based on tannic acid(TA),iron ion(Fe3+),and docetaxel(DOC)with microtubule inhibition,reactive oxygen species(ROS)generation,and glutathione peroxidase 4(GPX4)inhibition,is prepared for ferroptosis/apoptosis treatment.After internalization by CT26 cells,the DOC@TA-Fe3+nanoreactor escapes from the lysosomes to release payloads.The subsequent Fe3+/Fe2+conversion mediated by TA reducibility can trigger the Fenton reaction to enhance the ROS concentration.Additionally,Fe3+can consume gluta-thione to repress the activity of GPX4 to induce ferroptosis.Meanwhile,the released DOC controls microtubule dynamics to activate the apoptosis pathway.The superior in vivo antitumor efficacy of DOC@TA-Fe3+nanoreactor in terms of tumor growth inhibition and improved survival is verified in CT26 tumor-bearing mouse model.Therefore,the nanoreactor can act as an effective apoptosis and ferroptosis inducer for application in colorectal cancer therapy.
