Objective To measure the morphological parameters of the acromion with CT and to analyze their match with the hook plate. Methods From October 2009 to February 2010,spiral CT scanning (with Somatom Emotion16) and three-dimensional reconstruction of bilateral shoulders were conducted in 61 Chinese subjects.They were 24 men and 37 women,aged from 20 to 83 years (average,45.2 years).The thickness,length and width of the acromion were measured and the subacromial shape was observed with software of the CT system to analyze the match between the hook plate and the acromion.Results The mean thickness of the acromion was 0.85 ± 0.13 cm in all subjects,0.94 ± 0.12 cm in males and 0.79 ± 0.10 cm in fe males,with a significant difference between males and females ( t =2.382,P =0.202).The mean acromion length was 2.08 ± 0.20 cm in all subjects,2.09 ± 0.21 cm in males and 2.06 ± 0.18 cm in females,with no significant difference between males and females( t =1.541,P =0.129).The mean acromion width was 3.81 ± 0.52 cm in all subjects,4.34 ± 0.32 cm in males and 3.47 ± 0.25 cm in females,with a significant difference between males and females ( t =2.296, P =0.025 ). Conclusions The acromial morphology varies significantly between genders in Chinese population,particularly in the thickness and width.It is,therefore,necessary to modify the morphological parameters of the hook plate to match better the gender difference in Chinese population.It is optimal that the hook plate should allow individualized pre-moulding to enhance its therapeutic efficacy.

Objective To study whether there is correlation among the VEEG, head B ultrasound examination and NBNA score in evaluation of encephalopathy in premature infants. Methods One hundred cases of premature and low birth weight infants in our hospital from January 2012 to August 2013 admitted to NICU, were graded by video electroencephalogram, head B ultrasound examination and NBNA score to analyze the result of them in the assessment results encephalopathy in premature infants. Results In the treatment process, consistent with the EEG, head B ultrasound examination and NBNA score changes the presence of data results,with statistical significance. Conclusion There is a good correlation between VEEG,head B ultrasound examination and NBNA score.

Objective To investigate the clinical significance of the gray head B ultrasound quantitative determination on early detection for preterm low birth weight infants with cerebral white matter damage. Methods From 2013 January to August 2014 in the NICU department of our hospital, 100 cases of preterm and low birth weight infants were ran-domly divided into the treatment group and the control group. After birth 72 hours, the value of cerebral white matter was measured by head B ultrasound combined with medical image analysis software. The cases, whose early values of cerebral white matter were above 130, were treated with early brain nerve nutrition and rehabilitation. The develop-ment of nerve growth was followed up in 3 months and 6 months after birth, respectively. Results The NBNA score of premature and low birth weight infants was significantly higher than that of the control group. By the follow-up investi-gation in 3 months and 6 months after birth, the nerve growth of the treatment group was significantly better than that of the control group. Conclusion The head B ultrasound gray-scale quantitative analysis has important guiding signifi-cance for early diagnosis of premature and low birth weight infants with cerebral white matter injury,and it can help to judge the prognosis and guide early clinical treatment.

In order to clone and express alcohol dehydrogenase II (ADH2) gene from Saccharomyces cerevisiae in E. coli BL21 (DE3) efficiently, we extracted the total RNA as template and obtained ADH2 gene by RT-PCR and connected ADH2 gene to pTAT plasmids to gain recombinant expression plasmid pTAT-ADH2, then transformed this recombinant expression plasmid pTAT-ADH2 into E. coli BL21 (DE3). The recombinant was induced by IPTG to express ADH2. After purification, ADH2 activity was tested in vitro and toxicologic test was done in mouse. Sequence test showed that the acquired fragments exhibited 90% homology to ADH2 gene sequence from GenBank report. The target gene expressed efficiently and took up to approximant 50% of total protein by SDS-PAGE and band scanning analysis. The purified protein exhibited the identified activity through biochemical test and mouse toxicological test. As a result, the acquired ADH2 gene was highly homology to the published sequence and expressed at a high level in E. coli BL21 (DE3), more importantly, ADH2 proved to have ethanol dehydrogenase activity.

Objective To identify risk factors of systemic inflammatory response syndrome (SIRS) after percutaneous nephrolithotomy (PCNL).Methods We retrospectively reviewed 438 renal calculi patients after PCNL from August 2015 to July 2016.Among them,there were 251 men and 187 women,the mean age was (49.4 ± 11.1) years.The positive preoperative urine WBC,culture and nitrite rates were 29.7％ (130),12.1％ (53) and 15.1％ (66),respectively.The stone size was (851.2 ± 663.6) mm2,the stone CT value was (960.4 ± 303.4) HU,the operative time was (63.5 ± 33.4) min,124 (28.3 ％) were infection stones and multiple-tracts PCNL was performed in 69 (15.8％) patients.Univariate and multivariate logistic regression analysis were used to analyze perioperative predictors after PCNL.Results Thirty-nine patients developed SIRS (8.9％) after PCNL.The univariate analysis showed that positive preoperative urine WBC,nitrite,culture,operation time,stone size and transfusion had significantly impacts on the outcome of postoperative SIRS after PCNL (P ＜ 0.05).Multivariable logistic analysis showed that positive preoperative urine nitrite (OR =5.990,P ＜ 0.001),stone size (OR =2.251,P =0.027) and transfusion (OR =7.501,P =0.007) were independently related to the postoperative SIRS.Conclusion The positive preoperative urine nitrite,stone size and transfusion are independent risk factors for postoperative SIRS after PCNL.
