Objective To perform an anatomical study on anterior approach to fractures of the pelvis and acetabulum in an attempt to testify feasibility of the approach.Methods Position and variation of anatomical structure of the hypogastric abdominal wall and pelvic cavity were observed in 10 cadaveric adults (20 sides).Based on the anatomical study,anterior approach to pelvic fractures (n =20)and acetabular fractures (n =15) were performed and clinical results were observed.Results Anterior pelvic incision revealed no splitting or exposure of the spermatic cord/round ligament of uterus.Vertical incision through the muscle layer of abdominal wall located at lateral rectus abdominis and medial initial segment of hypogastric arteries/veins.In clinical practice,the approach revealed the mean incision length of 10 cm (range,9-12 cm) and mean blood loss of (225.5 ± 30.5) ml (range,170-350 ml).No injuries to femoral nerve and sciatic nerve occurred and there was no deep vein thrombosis.Surgical incision healed primarily.Bone union were recorded at the 18-month follow-up (11-35 months).Conclusions Anterior pelvic approach stretches the operative field from pubic symphysis to anterior-lateral cacroiliac joint and quadrilateral surface,allowing full exposure of the fracture site.The approach has benefits of high safety,minor trauma,large exposure,and satisfactory results and hence deserves wide application in clinical settings.

Objective To retrospectively analyze of clinical application of BF-XP60 micro-bronchoscopy.Methods 135 clinical data of patients who adopted ultrafine micro-bronchoscopy and intervention were collected and analyzed for the complications.Results The frequency of local rhinomusoca damaging and errhysis was in 3 cases,the mucous of the glottis damaging and errhysis was in 2 cases,local mucous of the tracheal bronchus errhysis was in 3 cases.After intervention,the frequency of fever was in 13 cases,massive haemorrhage was in 1 case,pneumothorax was in 1 case,chest pain was in 2 cases,part fiber of inner untrafine micro-bronchoscopy broken was in 2 cases,check failure due to ultrafine micro-bronchoscopy broken in trachea was in 4 cases,and arrhythmia,asphyxia,and death were in 0 case.The overall incidence of side effects was 22.9％ (31/135).Conclusion Application of ultrafine micro-bronchoscopy was contributed to find the lesions within the bronchioles and around the lungs,moreover,it could evaluate the distal bronchus of airway obstruction which was planned to adopt intervention.The topic that how to reduce the incidence of the side effects of the micro-brohchoscopy and improve the success rate and safety of inspection and intervention was worth to be concerned.

Objective To obtain the length-chest circumference index of normal term newborns in different gestational age. Methods By cross-sectional time cluster sampling fact-ifnding investigation method, the anthropometric data on 16388 newborns from 2013 to 2015 were measured, including birth weight, length, crown-rump length, head circumference, and chest circumference, to develop normal full-term infants height chest circumference index (BCI) in different gestational age. Results Anthropometric data of 13776 normal term infants were available at the end of the study. The BCI, Ververck Index (VI), Elisma index (EI) were increasing with the gestational age at newborn. BCI, VI, EI in male is less than those of female with signiifcant difference (P<0.05). There were some differences of newborn’s BCI, VI and EI in 2015 than those in 2005. Conclusion Com-pared to ten years ago, chest fullness increased with gestational age at different gestational ages in normal full-term infants, and the chest fullness in male is less than that in female.

[Absrtact] Objective To investigate the effect of anatomic quantitative target evaluation of class-room teaching on students' professional knowledge learning ability. Methods Twenty-five international students of 6-year program of grade 2013 were chosen as the experimental group, while twenty-seven Chinese students coming from the same class of grade 2013 and fifteen international students of 6-year program of grade 2012 were chosen as two control groups; quantitative and non-quantitative evaluation were imple-mented respectively by classroom questions and answers; teaching effects were evaluated by scales in the separation of teaching and examination, by records of answers for in-class questions and by questionnaire survey; SPSS 20.0 was used to make statistical analysis, one-way ANOVA and Kruskal Wallis test to com-pare the scores of three groups of students, P<0.05 indicates statistic significance. Results Compared with control groups, the accuracy of answers for class questions were improved greatly in the experimental group (2/3~3/4) vs. (1/2) and (2/3~3/4) vs. (1/2) and the average test scores (80.62±5.93) vs. (79.62±5.93) and (80.62 ±5.93) vs. (70.16 ±6.36) of the experimental group students were higher than control groups, the difference was statistically significant between the control group and the control group (P=0.045). Conclusions
Quantitative evaluation of teaching objectives in anatomy class can improve the learning attitude of foreign students and enhance their academic ability.

Objective To establish the Polock indexes (PI) of singleton neonates in different gestational age (GA),so as to provide a reference data for evaluating physical fullness and symmetry in neonates at birth.Methods A total of 16 887 live singleton neonates at 27-42 weeks of GA from two hospitals were measured at birth by site survey method using cluster samples by a cross sectional time in Shenzhen City,from 2013 to 2015 in this study,to establish PI of singleton neonates in different GA.Results The PI mean and the percentile curves(3rd,10th,25th,50th,75th,90th,97th)of singleton neonates at 27-42 weeks of GA (male,female,and unisex three groups) were established in 2015 in Shenzhen,China.The fullness and nutrition status of neonates at birth can be evaluated by these PI curves.According to the 3rd,10th,25th-75th,90th,97th curves,the down,mid down,middle,mid upper,upper levels were divided in turn.When the PI values ＞97th curve it was overweighted or fatty.When the PI values ＜ 3rd curve it was malnutrition.The lowest values of PI were at 27 weeks of GA,and the highest values appeared at 42 weeks of GA.The PI values were increasing with GA growth,which indicated that the GA increased the body density and fullness.The 50th percentile curve of male PI was higher than that of the female,and the male ratio increased by 61.2-89.5 at the gestational age of 27-34 weeks;between 35 and 42 weeks of fetal age,males increased by 104.8-149.1,which had a statistical difference (P ＜ 0.001).Conclusions The PI of singleton neonates rises with GA increase,which shows the GA increases the body density and fullness.PI is higher in male than in female singleton neonates.

Objective:To establish the HPLC fingerprint of Centellae herba and determine the content of asiaticoside, madecassic acid and asiaticoside B simultaneously; To compare the quality differences of Centellae herba collected in different months. Methods:The chromatographic condition was a Shimadzu InertSustain C18 column (4.6 mm×250 mm, 5 μm) with a mobile phase consisting of acetonitrile and 2 mmol/L beta cyclodextrin in gradient elution at the flow rate of 0.8 ml/min. The detection wavelength was 204 nm, and the column temperature was 30 ℃. The different Centellae herba materials of collected in 2-12 months from Chenzhou were studied by the similarity evaluation combined with cluster analysis, principal component analysis and the three contents determination. Results:The HPLC fingerprint of Centellae herba was established and 9 common peaks were designated. The eleven samples were different, which can be aggregated into 4 categories and the quality of Centellae herba collected in July was the best. Conclusion:The established fingerprint and multi-components quantitative method are stable and reliable, which can provide a reference for the quality control and the utilization of Centellae herba resource.
