Objective To evaluate the efficacy and safety of low-dose erythromycin for the prevention of feeding intolerance in preterm infants. Methods Fifty-two preterm infants (30-31 weeks' GA group) and 68 preterm infants (32-34 weeks' GA group) were randomly subdivided into prevention groups and control groups. From the second day the prevention groups received intravenously erythromycin [3 mg /(kg·d)] for 10 days,the control groups received placebo of glucose. Results In 30-31 weeks' GA group,days to achieve full enteral feeding (DAFEF) ,days to regain birth weight (DRBW) and duration of hospitalization (DH) were shorter in the prevention group as compared to those in the control group, the incidence of feeding intolerance was lower too,but there was no significant difference (P >0.05). In 32-34 weeks' GA group, DAFEF [(13.8±4.5) d],DRBW [(10.5±1.6) d],DH [(28.5±6.8) d] were significantly shorter in the prevention group than those in the control group [(17.2±4.2), (13.8±1.5), (35.5±7.2) d],the incidence of feeding intolerance in the prevention group was lower too[ 17.6%(6/34) vs 35.3%( 12/34) ], there was significant difference (P < 0.05 ). Conclusion In 32-34 weeks' GA, low-dose erythromycin can be a safe and effective method to promote food tolerance in preterm infants, but not sure in 30-31 weeks' GA.

Objective To find out the present situation of hepatitis B infection or immunity in Tianjin city,and to provide the scientific basis for the hepatitis B control and prevention.Methods 2 594 samples were selected with the methods of different proportionate stratified and cluster sampling,and the hepatitis B infection markers were detected by ELISA.Results The positive rates of HBsAg,anti-HBs,anti-HBc and HBV were 2.62%,46.72%,10.60% and 51.54%.Conclusion Compared with the results in 1992,the positive rates of HBsAg,anti-HBc and HBV were decreased significantly,while the positive rate of anti-HBs increased significandy,which ascribed to the comprehensive measure with the vaccination against hepatitis B as a main strategy for control hepatitis B.

OBJECTIVE:
To measure the anatomic data of the proximal femur and to design an internal fixation instrument aiming at subtrochanteric fracture.
METHODS:
We measured the anatomic data of 56 pairs of the matching proximal femur specimens: the diameter of femoral head (HD), the axis length of femoral head (HAL), 135 degree femoral head-neck axis length (HNAL), 135 degree femoral head-neck axis upper length (HNAUL), 135 degree femoral head-neck axis underside length (HNADL), the anterior-posterior axis diameter of femoral neck (NAPD), the upper-underside diameter of femoral neck (NUUD), femoral neck-shaft angle (NFA), femoral shaft lateral cortex-greater trochanter angle (SLGA), the medial-lateral diameter of lesser trochanter level's femoral shaft (LSMLD), the anterior-posterior diameter of lesser trochanter level's femoral shaft (LSAPD), the medial-lateral diameter of 5 cm below lesser trochanter femoral shaft (5 cm MLD), and the anterior-posterior diameter of 5 cm below lesser trochanter femoral shaft (5 cm APD). Part of the data was analyzed and compared.
RESULTS:
HD was (46.69+/-3.73) mm, HAL was (39.22+/-4.17) mm, HNAL was (95.45+/-8.16) mm, HNAUL was (84.02+/-7.11) mm, HNADL was (99.95+/-9.34) mm, NAPD was (26.27+/-3.15) mm, NUUD was (32.24+/-3.31) mm, NFA was 126.21 degree+/-7.13 degree, SLGA was 16.38 degree+/-4.04 degree, LSMLD was (31.05+/-3.57) mm, LSAPD was (27.63+/-2.96) mm, 5 cm MLD was (26.36+/-3.22) mm, and 5 cm APD was (25.59+/-2.75) mm. NFA was positively correlated with SLGA (r=0.396, P=0.003).
CONCLUSION
It is necessary to design internal fixator to fit the anatomical feature of Chinese femur for the treatment of subtrochanteric fracture, and we should thoroughly consider the angle of the SLGA.

Objective:To compare the value of Caprini, Padua and Autar risk assessment models in the risk assessment of venous thromboembolism in hospitalized stroke patients.Methods:A retrospective case-control study were used to collect hospitalized stroke patients in the neurology department of Xiangya Hospital from January 1, 2018 to June 30, 2020. 75 patients with venous thromboembolism (VTE) were VTE group and 75 patients without VTE were control group. The risk of thrombosis was assessed by Caprini risk assessment model, Padua risk assessment model and Autar risk assessment model respectively. The predictive value of each model on the risk of VTE formation in stroke patients was analyzed by receiver operating characteristic (ROC) curve and area under the curve (AUC).Results:The areas under the curve of Caprini, Padua and Autar risk assessment models for predicting the risk of VTE formation in stroke patients were 0.768±0.039, 0.746±0.040 and 0.710±0.042 respectively. The sensitivity, specificity and accuracy were 81.3%, 61.3%, 71.3%(Caprini), 72.0%, 72.0%, 72.0%(Padua), 66.7%, 68.0% and 67.3%(Autar) respectively. There was no significant difference in the prediction value of the three models on the formation risk of stroke VTE (all P>0.05). The technique for order preference by similarity to ideal solution (TOPSIS) method was used to comprehensively evaluate the AUC, sensitivity, specificity and accuracy of the three risk assessment models. Padua risk assessment model was the best, followed by Caprini risk assessment model and Autar risk assessment model. Conclusions:The Caprini, Padua, and Autar risk assessment scales can well predict the risk of VTE in stroke patients. The Caprini scale has the highest sensitivity and the Padua scale has the highest specificity. There is no significant difference in the predictive value of the three scales. Comprehensive evaluation of predictive value: Padua risk assessment scale is the best.

Objective To investigate the training expectations and training strategies of orthopedic clinical specialist nurses (OCSN).Methods Totally 5 020 orthopedic nurses from 342 hospitals from 30 provinces and cities were selected bv convenience sampling.Participants were investigated hy WeChat platform with self-designed questionnaire.Results A total of 4 982 effective questionnaires were collected.Among investigated nurses,13.7% of them received orthopedic specialist nurses training;91.4% believed that training should be carried out.Qualifications should be:college degree and above,senior nurse and above,at least 3 ~5 years of nursing experience,1~3 years of nursing experience in orthopedic department.For curriculum,public courses expected to be arranged were communieation skills,nursing teaching,nursing management,and nursing research;expected professional courses were functional exercises,pain management,extremity injury nursing,common treatment techniques in orthopedic department,traction nursing,and position nursing.It was suggested that training was divided into subspecialties and off-duty;classroom teaching,teaching rounds,case discussion and experience exchange were expected training methods;"theory-practice-theory-practice" was most preferable traiuing mode.The preferred teachers were orthopedic doctors,orthopedic head nurses,orthopedic specialist nurses,and senior orthopedic nurses.The length of training was expected to be three months,time for clinical practice should be greater than or equal to theoretical teaching,and the practice bases should be tertiary hospitals.Evaluation should be performed before completion,recertification could be later than completion,and the interval time of recertification should be within 5 years.Conclusion Training needs of orthopedic nurses for OCSN are strong.Training expectations(contents,length,modes and teachers) of orthopedic nurses should be considered when designing systematic training program on OCSN.
