Objective To discuss the technique and value of preoperative reformatting with three-dimensional computed tomography technique for C_2 pedicle screw track.Methods GE Light Speed 16 Pro spinal CT scans of 15 adult dry vertebrae were loaded into an imaging station (software ADW4.2).Two methods of C_2 pedicle screw techniques were analyzed through virtual screw trajectory by VR (volume rendering) and MPR (multiple planar reformatting) techniques,in method A,screw entry point was the intersection between the media-vertical and the cranial line of C_2 inferior facet joint,in method B,the screw track was from the cranial and medial quadrant of the dorsal part of C_2 inferior facet joint.Results The screw track could be observed dynamically from any plane.Two vertebrae were ob- served with smaller height in isthmus and the medial edge of the transverse foramen since no space was a- vailable for the screw.The screw trajectories data were compared between method A and method B,which showed that the angles towards the cephalad (in sagittal plane) and midline (in transverse plane) were bigger in method A than in method B (P＜0.05,0.01),but the safe screw diameter was smaller in method A than in method B (P＜0.05),and there was no difference of the screw length between the two methods(P＜0.05 ).Conclusion In this research,the individual C_2 pedicle screw entry points, screw diameter and security screw angle can be simulated,and the screw track can be observed dynami- cally to make sure if it transits the bone structure completely.Preoperative three-dimensional computed tomography reformatting for pedicle screw track is of great value in clinical and basic researches.

Objective To investigate the penetrative ability of amlodipine gels and to evaluate their effect on the survival of rat dorsal ischemic random skin flaps.Methods 0.5 ％,1.0 ％,1.5 ％,2.0 ％,and 2.5 ％ amlodipine gels were made.The accumulative penetrative quantities of amlodipine through rat skin were assayed with a modified Franz's diffusion cell in vitro.Pure gel without amlodipine,0.5 ％ and 1.5 ％ amlodipine gel were respectively applied on rat random ischemic skin flap once a day for 7 days.The viable area was measured on the seventh postoperative day and the quantities of amlodipine within skin flap were also detected at 2 and 6 hours after application of amlodipine gel.Results The accumulative penetrative quantities of amlodipine increased in time-and concentration-dependent manner (P＜0.05).Accumulative quantities of 0.5 ％ and 1.0 ％ amlodipine gel were lower than those of 1.5 ％,2.0 ％,and 2.5％ gel,respectively (P＜0.05).The quantities of amlodipine within flap tissue in 1.5 ％ amlodipine gel was higher than that of 0.5 ％ amlodipine gel (P＜0.05).The survival area of flap in 0.5 ％ amlodipine gel group (391.4±65.4) mm2 was higher than those of the pure percutaneous gel group (192.9±56.8) mm2 and the control group (191.0±50.2) mm2(P＜0.05),but no significant difference was seen between 1.5 ％ amlodipine gel group (265.7+88.3) mm2 and control group (P＞0.05).Conclusions Amlodipine could penetrate into skin tissues.0.5 ％ amlodipine gel could significantly increase survival area of ischemic random skin flap.

Objective To predict monthly incidents of extended spectrum β-Lactamases (ESBLs)-producing Escherichia coli in Zhejiang Hospital by establishing multiple seasonal autoregressive integrated moving average (ARIMA) model, so as to provide scientific evidence for reducing the incidents of nosocomial infection of ESBLs producing Escherichia coli. Methods Multiple seasonal ARIMA model was established by monthly records of ESBLs producing Escherichia coli from 2010 to 2016 in Zhejiang hospital. Monthly incidents of ESBLs producing Escherichia coli from 2017 to February 2018 were used to verify the predicted result. The predictions were evaluated by models of mean absolute percent error (MAPE) and bayesian information criterion (BIC) . Results The optional model for the monthly incidence from 2010 to 2016 was ARIMA (0, 1, 1) (0, 1, 1)12. The MAPE was 14.76, BIC was 2.01, and the Ljung-Box statistics value Q was 16.79 (P=0.40) . These parameters suggested a good model fitting. The average relative error between the predictive value and the actual value of the monthly incidents ESBLs producing Escherichia coli from 2017 to February 2018 was 14.08%.The actual values were within the 95% confidence interval. Conclusion The multiple seasonal ARIMA model of ARIMA (0, 1, 1) (0, 1, 1 )12 fits and can be used for short-term prediction and dynamic analysis of the incidents of ESBLs producing Escherichia coli in Zhejiang Hospital.

The required time of conventional magnetic resonance spectroscopic imaging technique is too long to be applied to clinic. It is necessary to develop the fast methods for magnetic resonance spectroscopic imaging. Nowadays there are 7 kinds of methods presented, which come from MRI techniques. In this contribution the conventional spectroscopic imaging and 7 sorts of fast spectroscopic imaging are elaborated. It is envisaged that more rapid imaging techniques will be designed, if these arbitrary trajectory reconstruction methods in MRI are applied to spectroscopic imaging.

Objective To study the expression of KAI1 and CD40 in gastric cancer and their correlation with clinicopathologic features and prognosis.Methods The expression of KAI1 and CD40 of 64 gastric cancer tissues was examinated by S-P immunohistochemieal methods.Results The overall positive rate of KAI1 was 22% in gastric cancer.Expression of KAI1 was positively related to the degree of tumor differentiation,it was negatively related to invasion depth and lymph node metastasis and the tumor clinical stage.The 5-year survival rate of cases with positive expression of KAII was significantly higher than that of cases with negative expression(X~2=42.426,P=0.000).The expression rate of CD40 in gastric cancer tissue was 34%.The expression of CD40 was significantly correlated with metastasis and clinical stage of gastric cancer.The 5-year survival rate of cases with positive expression of CD40 was significantly lower than that of cases with negative expression(X~2=4.841,P=0.028).There is no relationship between KAI1 and CD40 expression in gastric cancer.Conclusion KAI1 is associated with gastric cancer differentiation,invasion and metastasis.CD40 status helps to evaluate metastasis,and predict prognosis of gastric cancer.

Objective: To evaluate the impact of CO₂ pneumoperitoneum in operating rooms on the health of medical staffs. Methods: In June 2016, the thirty-three medical staffs in operating rooms were chosen as the object of the research.Seventeen people who took part in the pneumoperitoneum operation were selected as a exposure group and sixteen people who took part in the laparotomy operation were selected as a control group.Vital signs and arterial blood gases of medical staffs in the two groups were both measured in pre-operation and post-operation. Occupational Health Questionnaires were conducted to collect information on age, weight and postoperative symptoms. The level of CO₂ in operating room was determined by a portable infrared CO₂ analyzer. Results: Compared with the control group, the concentration of CO₂ in the exposed group was higherat T₁, T₂ and T₃ (t=22.227, 13.583, 17.408, P<0.05) . Heart rates and PaCO₂ in the exposure group raised greatly (t=2.132, 2.129, P<0.05) , while pH decreased (t=-3.015, P<0.05) . The differences between the two groups were statistically significant. Conclusion The increase of mild acidosis and thesense of job burnout in medical staffs could be caused by CO₂ pollution in the operating rooms.
