Objective This article aim to optimize facial characteristic indexes and to establish the standard of classiifcation by studying positive photos of Chinese Han nationality adults, and to investigate the personal identiifca-tion power ifnally. Methods Firstly, we determined the 27 facial characteristic indexes and standard of classiifcation. Secondly, we observed 254 positive photos of Chinese Han nationality adults. Finally, indexes and standard of classi-ifcation are evaluated through statistically analysising of observation data results and calculating personal identiifcation capability. Results Thirteen indexes gender differences are signiifcant. All 27 facial characteristic indexes are calculated. Male TDP(total discrimination power)=0.999 999 909 08, female TDP=0.999 999 919 82, overall TDP=0.999 999 868. Conclusion The more facial characteristic indexes and the more classiifcation and the higher degree of classiifcation, the higher personal identiifcation ability can be acquired.

Objective This article aims to investigate the effect of gender determination for measuring the 12th Thoracic Vertebra by using computed tomography (CT) and explore the feasibility for the research of human skeleton measuring by CT technique in the ifeld of forensic anthropology.Methods After ascertaining 11 radial line indicators,we measured Multi-planner Reformation (MPR)image of the 12th Thoracic Vertebra. Four ratio indicators were calculated after eliminating measurement uncertainty of results. We inspected the effect of gender determination for measuring the 12th Thoracic Vertebra by using computed tomography (CT) on account of statistical measurement data.Results Gender determination of 12 indicators is remarkable after eliminating 3 unstable indicators. Sevene quations were established. The equation established by centrum indicators predicted sex up to 91.6% accuracy.Conclusion The morphometry indicators of 12th Thoracic Vertebra have gender difference. CT technology can accurately measure skeleton and is valuale for study of human skeleton measuring research in the ifeld of forensic anthropology.

OBJECTIVE: To investigate postoperatively repairing methods and their clinical effects of the olders over 80 years old with head and facial skin malignancies. METHOD: Eighteen cases of skin cancers in the head and face, whose malignancies were resected with Mohs microscopic surgery, according to the local or systemic condition of patients after surgery we choose different repairing methods: free skin flap grafting in 2 cases, local skin flap transferring 12 cases; including rotation skin flap grafting 6 cases, sliding flap 4 cases, nasolabial flap 2 cases; transposition flap 4 cases. RESULT: Operations of the 18 cases went well without special complications. All of the flaps were alive with partial flap necrosis in 1 case, which was cured 1 month later by dressing changes. During the follow-up period ranged from 6 months to 2 years,no tumor recurred,the functional recovery and appearance were satisfactory. CONCLUSION Choosing operating methods in head and facial skin malignancies should consider patients' age, disease state and general condition. Reparing methods of Head and facial skin malignancies in the advanced ages should be selected according to their specific circumstances, especially the simple, convenient and rapid with less trauma way.

Objective To investigate the effect of curosurf in treatment of children with hyaline membrane disease and the nursing. Methods 56 cases of children patients with hyaline membrane disease from June 2008 to June 2010 admitted to neonatal wards were selected. The control group (26 cases)treated with mechanical ventilation alone and corresponding conventional care, on this basis, the treatment group (30 cases) was treated with curosurf and give systemic nursing intervention. Symptomatic relief time, mechanical ventilation time, length of stay, complication incidence rate, death rate, PaO2 and PaCO2 before and after treatment were observed in two groups. Results Symptomatic relief time, mechanical ventilation time, length of stay, complication incidence rate in the treatment group was significantly lower than that in the control group; PaO2 and PaCO2 amelioration in the treatment group was better than the control group. Conclusions Children with hyaline membrane disease should be treated with curosurf and given systemic nursing intervention as early as possible, it can rapidly improve the symptoms of hypoxia, reduce complications, decrease mortality, accelerate the recovery of disease.

Objective To evaluate the efficacy in treatment with transurethral electrocision for prostatic cyst.Methods A total clinical documents of 15 cases prostatic cyst treated with transurethral electrocision were analyzed retrospectively.All the cases were diagnosed confirmly by ultrasonography and CT,all the cysts closed to the prostatic urethra or intrude urinary bladder and all the patients underwent transurethral electrocision.Results All operations were performed successfully with operative time of 18-60 (36 ± 13) min.No blood transfusion during and after the operation and postoperative hospital stay was (5.2 ± 2.6) d.All the patients had been followed up for 6-24 months,the clinic symptom disappeared and no complications happened.Three months after the operation,IPSS decreased from (27.2 ±5.6) scores to (7.5 ± 1.6) scores and QOL decreased from (4.5 ± 1.1 ) scores to ( 1.6 ± 0.6) scores (P＜ 0.01 ),respectively.Qmax increased from (6.8 ±2.3) ml/s to (22.4 ±4.8) ml/s (P ＜0.01).Conclusion Transurethral electrocision is an effective therapeutic measure of prostatic cyst close to the prostatic urethra or intrude urinary bladder without so many complications.

Objective To investigate the relationship between the ADAM gene expression and unknown reason infertile patients. Methods With RT-PCR mehtod, we checked from normal group semen 30 cases and infertile group semen 30 cases in order to know the ADAM1,2,3,32 mRNA expression. Results there are the ADAM1,2,3,32 gene expression in all 30 cases of normal group whereas in 30 cases infertile patients there exists 1 case ADAM1,2,32 lacking expression, 1 case ADAM2,32 lacking expression, 1 case ADAM1 and 1 case ADAM3 lacking expression. Conclusions The lacking of ADAM1,2,3,32 may be one of the most reasons which cause the infertility.

Objective To design an automated detection protocol for morphological detection of sperm head based on deep learning and evaluate its efficiency,accuracy and reliability.Methods Fourteen pictures for each of 1 000 samples were analyzed by using the pre-trained YOLO target detection model and VGG16 classification model.At least 200 sperm were detected for each sample.Equal amount of samples were analyzed by manual microscope examination,and the efficiency,accuracy and correlation between the two methods were compared.Results The morphology of sperm heads which were manually classified but untrained was detected by pre-trained classification model,and the prediction accuracy reached to 95.5％.The detection time for clinical each sample was only 10 seconds,and its accuracy and efficiency were higher than those of manual microscope examination.The percentages of the sperms with normal morphology were significantly positively correlated(r=0.84,P＜0.01)in the detections of both the methods.Conclusion The detec-tion protocol proposed in this study can greatly improve work efficiency,and its reliability and accuracy exceed those of manual micro-scope examination.
