Objective To analyze the epidemiological characteristics of unintentional injuries among children patients at age of ≤ 14 years so as to provide scientific basis for prevention of the children injury. Methods ICD-10 coding was used to retrospectively analyze the epidemiological characteristics of the children patients with unintentional injuries at age of ≤ 14 years admitted from January to December 2009 and the factors affecting the prognosis were discussed. Results There were 3011 patients, with 1991 males (66.12%) and 1 020 females (33.88%). The patients at ages of < 1, 1-4, 5-9 and 10-14 years accounted for 8.24%, 53.30%, 27.90% and 10.56% respectively. The patients from the rural and urban areas accounted for 56.16% and 43.84% respectively. Trauma was the leading sort of injuries in four age groups, accounting for 70.56%, 62.68%, 89.64% and 87.74% respectively. Fall from height was the first cause of unintentional injuries in four age groups, with proportion for 47.58%,36.39%, 51.90% and 56.29% respectively. Muhinomial logistic regression analysis revealed that hospital stay, therapeutic mode ( operation/non-operation), inhabitancy ( urban/rural), causes of injuries and injury severity on admission were the risk factors affecting the prognosis (P < 0.05 ). The rural areas caused higher risk of disability than the urban areas ( OR = 2. 170 ,P < 0.01 ) and non-operation produced higher risk of death than operation (OR = 6.352,P < 0. 01 ). Conclusions The male patients with unintentional injury are more than the female ones, with the highest incidence rate in children at age of 1-4years. Trauma is the main kind of unintentional injury and the fall from height the leading cause of injury.The difference of the rural and urban areas indicates that correct choice of the preventive measures based oh the condition of the local area can attain effective prevention and control of the unintentional injuries.

Objective To study the homology and clinical distribution of tigecycline-resistant Acinetobacter baumannii (A.baumannii )in a hospital.Methods Multidrug-resistant A.baumannii (MDRAB,n = 88 )from specimens from clinical departments of a hospital in 2013-2014 were collected and detected susceptibility to tigecy-cline;homology of tigecycline-resistant strains were detected by pulsed-field gel electrophoresis (PFGE),clinical characteristics and distribution of infected patients were analyzed.Results 88 patients didn’t use tigecycline before MDRAB were isolated.Of 88 MDRAB strains,4 (4.55%)were resistant to tigecycline,which were No.10,31 , 33,and 87 strains.PFGE results revealed that No.31 ,33,and 87 strains were of the same genotype,and with high homology,which distributed in three different departments;No.31 strain was detected from general intensive care unit (ICU),No.33 strain was detected from emergency ICU,although strains were detected from different depart-ments,patients were transferred before strains were isolated,and were admitted to departments of gastrointestinal surgery and emergency ICU during the same period;No.87 strain was detected from neurosurgical ICU and patient had never been transferred,the detection time was 7-8 months later than No.31 and 33 strains.No.10 strain was isolated from emergency ICU,patient was not transferred.Conclusion Of MDRAB isolated in this hospital,tigecy-cline-resistant strains are low,most strains are homologous,cross infection may be exists in different departments.

Objective To investigate the effect of diabetes on clinical efficacy of transcatheter arterial chemoembolization (TACE) in the treatment of non-viral hepatitis hepatocellular carcinoma (HCC). Methods Retrospectively analyzed the clinical data of 367 non-hepatitis virus HCC patients treated by TACE, included 153 diabetes mellitus cases (test group) and blood glucose of 214 patients was normal (control group). To assess the treatment effect after 1 month of TACE based on response evaluation criteria in solid tumors, include complete response (CR), partial response (PR), stable disease (SD), progressive disease (PD), and calculate the disease control rate. Through 6 to 75 months follow-up to observed long-term efficacy, record the time to progression (TTP) and overall survival (OS) time. Survival rate were analyzed using Kaplan-Meier method and Log-rank analysis by SPSS 16.0. The single-factor analysis was used to analyze variables which variables that differed were analyzed by Cox regression. Results The disease control rate of test group was 69.9%(107/153) and control group was 74.3%(159/214), the difference was no statistically significant (P=0.125). The median time to progression (mTTP) and median overall survival (mOS) of test group were 10.0 and 15.0 months;and the mTTP and mOS of control group were 14.0 and 19.0 months, the difference were statistically significant (P=0.023 and P= 0.026). Tumor diameter ≥4.5 cm, numbers of tumor ≥3, invasion of blood vessels, α-fetoprotein≥200 μg/L, Eastern Cooperative Oncology Group score and diabetes were risk factors for OS of HCC patients. Conclusion Diabetes is unfavorable factors for overall survival of non-hepatitis HCC tread by TACE.

Objective? To analyze the bias of dimension measurement results of penis and testis by the self-design cylinder boy penis and testicles measurement (hereinafter called cylinder ruler) and it influencing factors. Methods? From June to December 2018, we selected 152 children of Department of Urinary Surgery in Hu'nan Children's Hospital as subjects by case sampling. Children's penis and testicles dimension were measured repeatedly by their patients and nurses with the self-designed cylinder ruler and three kinds of common clinical measurement tools (vernier caliper+tape measure+testis measurer, vernier caliper+straightedge, vernier caliper+round head probe), and the bias were counted based on medical reference value. Results? Measurement bias of length and diameter of penis in a resting state, length of penis in a traction state, length and width of testis in group of cylinder ruler were lower than those in other groups with statistical differences (P＜0.05) which not influenced by boys' ages and measurement time (P＞ 0.05). Bias of length of penis in a traction state, length and width of testis measured by nurses were lower than those by children's patients with statistical differences (P＜ 0.05). Interaction effect analysis showed that there were no statistical differences in dimension of penis and testis measured by different measurers with the cylinder ruler (P＞0.05); however, there were statistical differences in dimension of penis and testis measured with the cylinder ruler by different measurers at different times of a day (P＜0.05). The differences of interaction effects between measurement time and measurers were statistical (P＜0.05). Conclusions? Compared with other measurements, the self-designed cylinder ruler for measurement of penis and testis in boys has higher accuracy. The main influencing factors of bias of dimension of boys' penis and testis are ages of boys and measurement time. Bias of length of penis in a traction state, length and width of testis measured by nurses are lower than those by children's patients. Measurers and measurement time are not suggested as independent factors when analyzing the influencing factors of dimensions measurement bias of penis and testis. Dimensions of penis and testis are measured with the cylinder ruler at different times which have certain changes.

Objective To systematically evaluate the risk prediction models of diabetic foot infections,and to ex-plore its implications for clinical nursing care.Methods Relevant studies in the databases of CNKI,VIP,Wanfang,CBM,CINAHL,PubMed,Web of Science,Cochrane Library,Embase,ProQuest,and Ovid were searched for the time-frame of database construction to December 2023.Literature was screened independently by 2 investigators and the area under the model curve(AUC)and its 95％confidence interval(CI),calibration method and predictors were ex-tracted,and the quality of the model was evaluated using the Predictive Modeling Study Risk of Bias Assessment Tool.Meta-analysis of the predictive value of model predictors was performed using RevMan 5.4 software.Results 7 studies were included,containing 8 risk prediction models,all of which reported the AUC(0.748-0.922),and 6 models underwent model calibration.The overall fit of the included studies was good,among which l model was low fit,and all 7 studies were at high risk of bias,mainly focusing on predictors and analysis.Meta-analysis showed that the area under the curve of the combined models was 0.831(95％CI:0.780～0.883);the disease duration(OR=2.460,95％CI:1.850～3.270),vascular disease(OR=3.110,95％CI:1.070～9.000),and neuropathy(OR=3.550,95％CI:1.920～6.560)were effective predictors of diabetic foot infection.Conclusion The current diabetic foot infection risk prediction model is still in the developmental stage,and further optimization and external validation of the ex-isting model is recommended for the future.
