Objective To illustrate the different levels of fundamental nursing skills of undergradu ate nursing students,and explore the characteristics of the assessment method.Methods With descriptive statistics,one-way analysis of variance after rank transformation,and multiple comparison (Scheffe),we made an analysis of 1 340 assessment records of fundamental nursing skills.Results The score distributions of all the skills,but the skill of measuring vital signs,conformed to Gaussian distribution.The overall distribution shaped in peak state and was negative skewness,showing bias towards 70 to 90 score levels.The score levels of 60 and 70 were significantly higher than that of their surrounding levels.The scores of aspiration of sputum,oxygenic therapy and aseptic technique were the lowest,while the scores of closed bed making and intramuscular injection were the highest.Conclusions The score distribution of fundamental nursing skills is rational,which shows the methods of teaching and assessment are generally believable.But the individual bias cannot be ignored.The majority of students get high grades.Different levels do exist among different skills because of abstract or concrete characteristics and principal matters.

Objective To clone express and purify Schistosoma japonicum fructose?1 6?bisphosphate aldolase SjFBPA in E. coli and observe its expression in different developmental stages of S. japonicum. Methods FBPA gene was amplified from S. japonicum adult worm cDNA by using PCR. The amplified product was recombined into pET28a plasmid and inducibly expressed with IPTG in E. coli BL21. SDS?PAGE and Western blotting were employed to analyze and identify the recombinant protein SjFBPA rSjFBPA . Then rSjFBPA was purified by chromatographic purification and its purity was analyzed by SDS?PAGE. The protein concentration of rSjFBPA purified was measured by the BCA method. Furthermore SjFBPA mRNA was ana?lyzed in different developmental stages of S. japonicum by RT?PCR. Results SjFBPA was successfully amplified by using PCR and identified by restriction enzyme digestion and sequencing. The Western blotting analysis confirmed that the recombinant pro?tein could specifically reactive to the anti?His?tag monoclonal antibody. The concentration of the purified recombinant protein was about 4 mg/ml. The result of RT?PCR showed that SjFBPA mRNA was expressed in cercaria schistosomulum adult worm and egg of S. japonicum. Conclusion SjFBPA is successfully recombined and expressed in a prokaryotic system and SjFBPA mRNA is expressed in cercaria schistosomulum adult worm and egg of S. japonicum.

Objective To explore the relationship between cervical bone age and male juvenile mandibular second molar (Msm) root growth ,and to provide evidence for the development of bone and teeth in patients with orthodontic treatment . Methods The CBCT and lateral cephalometric radiographs of 114 cases of 9 .5 to 15 .5 years old children in Chongqing city and ad‐olescents cervical vertebral bone and MSM root length were measured ,using statistical analysis to explore the relationship between cervical vertebral bone ,tooth root length change of age and Msm .Results By Pearson correlation analysis ,Msm root length chan‐ges and cervical vertebral bone were positively correlated(r= 0 .737 ,P< 0 .01) .Msm root length changes showed a positive correla‐tion with age(r= 0 .681 ,P< 0 .01) .Msm root length changes was positively related with dental age(r = 0 .795 ,P< 0 .01) .Conclu‐sion The root growth of the mandibular second molar was highly correlated with cervical vertebral bone in male children .When the growth and development of patients were judged by orthodontic treatment ,we can adopt the mandibular second molar root length forecast growth level of male adolescents .

Objective To investigate the effect of the humanized care on the blood glucose, blood lipid and diabetic ketoacidosis control of type 1 diabetes patients outside the hospital. Methods Fifty type 1 diabetes patients were enrolled in this study, aged from 18 to 30 years old, outside the hospital. The duration of this study was from Mar 2009 to Jan 2016.The clinical and laboratory data of patients,including HbA1c,LDL-C,HDL-C,TG and diabetic ketoacidosis were collected and analyzed. Results About 60.0% and 80.0% of type 1 diabetes pa-tients achieved the goals of contorlling glycemia (HbA1c < 6.5%) and dyslipidemia (LDL-C < 2.6 mmol/L) respec-tively, after receiving the humanized care outside the hospital, while only 32.0% and 22.0% of type 1 diabetes pa-tients achieved these goals before.Moreover,after receiving the humanized care outside the hospital,only 16.0% of type 1 diabetes patients suffered from diabetic ketoacidosis which was 40.0% before.Conclusions The humanized care outside the hospital can help patients to acheive the goals of contorlling glycemia and dyslipidemia among the type 1 diabetes.Besides,it contributes to reduce the incidence rate of the diabetic ketoacidosis.

Objective To explore whether augmenter of liver regeneration (ALR) can serve as early diagnostic biomarker in the patients with acute kidney injury(AKI).Methods The inpatients with possibility to AKI in the central ICU of Second Affiliated Hospital of Chongqing Medical University from October 2014 to October 2015 were recruited and assigned to the AKI group and non-AKI group according to the KDIGO guidance.Blood and urine ALR and blood creatinine were detected at 0,6,12,24,48,72 h after entering the group.Results Among all cases,40 cases(62.5％) developed to AKI.Blood ALR and urine ALR at 6h after entering the group in the AKI group began to significantly increase compared with the non-AKI group(P＜0.05),the blood and urine ALR levels reached to the peak value at 12,24 h after entering the group;the blood creatinine level at 12 h after entering the group in the AKI group began to significantly increase compared with the non-AKI group(P＜0.05),blood creatinine level was still slowly and progressively elevated at 72 h after entering the group.Conclusion Serum and urine ALR levels are significantly increased in the early stage of AKI,which indicates that ALR may be a new type biomarker for diagnosing AKI.

Objective To investigate the status of familial aggregation of Helicobacter pylori (Hp) infection in Jinniu District, Chengdu, and analyze its risk factors so as to provide a basis for developing prevention and control strategies of family aggregation of Hp infection. Methods A total of 172 subjects in the Second Affiliated Hospital of Chengdu Medical College · 416 Hospital of Nuclear Industry from January 2022 to January 2023 were selected as the research subjects. All subjects underwent 13C-urea breath test (13C-UBT) to diagnose whether there was Hp infection. Analyze the current situation of family aggregation of Hp infection in the region, collect general data of survey subjects, analyze the relevant factors affecting Hp family aggregation infection, and develop prevention and control strategies based on this. Results A total of 242 people from 97 households were surveyed, and the Hp family aggregation rate was 29.33%. Univariate analysis showed that there were statistically significant differences in family aggregation of Hp infection in terms of different age groups (χ²=9.719, P=0.008), marital status (χ²=8.496, P=0.014), occupations (χ²=19.462, P<0.001), frequencies of dining out (χ²=5.457, P=0.019), previous Hp test results (χ² =4.131, P=0.042) and test results after treatment (χ²=12.000, P=0.001), with statistical significance (P<0.05). Multivariate logistic regression analysis showed that the frequency of dining out 2 days or more per week and a positive Hp test results in the past were risk factors for family aggregation of Hp infection, while the occupation of teachers/medical staff/management/technology personnel and a negative Hp results after treatment were protective factors (P<0.05). Conclusion Family aggregation of Hp infection is related to family members' occupation, frequency of dining out, previous Hp test results and Hp test results after eradication, which deserves attention in clinical practice.
