BACKGROUND: It is of great significance to understand the effects of different components of blood pressure on the occurrence of cerebrovascular diseases and administer proper decompression treatments in various situations.OBJECTIVE: To study the relationship of increased pulse pressure with the occurrence and severity degree of cerebral infarction by analyzing the data of pulse pressure recorded in hospitalized patients with acute cerebral infarction.DESIGN: Case-control analysis.SETTING: First Affiliated Hospital of Harbin Medical University.PARTICIPANTS: A total of 300 patients hospitalized at the First Affiliated Hospital of Harbin Medical University between June 2002 and January 2003 for ischemic cerebral infarction were enrolled, including 196males and 104 females aged (57.9±11.9) years. Another 199 persons who came to the same hospital for physical examination at the same period were set as normal group, including 110 males and 89 females aged (55.9±12.4)years.METHODS: ① Measurement of blood pressure: Systolic pressure and diastolic pressure of each person were recorded with mercury sphygmomanometer at the site of brachial artery of the right upper extremity and pulse pressure was calculated. ② Evaluation of neurological impairment:Upon hospital admission, each patient with ischemic cerebral infarction was evaluated with the stroke scale made by the National Institute of Health (NIHSS), in which a higher score means more severe infarction.MAIN OUTCOME MEASURES: ① Comparison of blood pressure parameters of subjects in the two groups. ② Distribution of different pulse pressure levels in the two groups. ③ Comparison of pulse pressure of subjects of different age in the two groups. ④ Results of non-parameters tests of neural function loss in cerebral infarction patients with different pulse pressure levels.RESULTS: ① Mean systolic pressure: It was significantly higher in the case group than in control group [(152±22), (133±19) mm Hg, t' =10.494,P ＜ 0.01]. Mean diastolic pressure: It was higher in the case group than in control group [(93±14), (81±11) mm Hg, t' = 10.129, P ＜ 0.01]. Meanpulse pressure: It was higher in the case group than in control group [(59.61±11.86), (51.93±14.10) mm Hg, t' =5.612, P ＜ 0.05]. Pairwise corre lation analysis showed that Pearson correlation coefficient between pulse pressure and systolic pressure was 0.789 (P ＜ 0.01); Pearson correlation.coefficient between pulse pressure and diastolic pressure was 0.169 (P ＜ 0.01). Therefore, there was a close correlation between pulse pressure and systolic pressure. ② Pulse pressure was distributed between 60 mm Hg and 69 mm Hg in most subjects in the case group, which accounted for 27.7%.It was 40-49 mm Hg in control group, which accounted for 35.7%. It indicated that the incidence rate was high when the pulse pressure was over 60 mm Hg in cerebral infarction. ③ Pulse pressure increased with age.The level of pulse pressure in 40-69 years case group was higher than that in 40-69 control group [(54±16), (45±9)mm Hg, t=4.86, P=0.000]. ④ Patients with cerebral infarction of different levels of pulse pressure were given non-parameter tests of neurological impairment evaluation. The resuits of Kruskal-Wallis test were χ2=4.779, P=0.572 ＞ 0.05; results of median test were as x2=8.365, P=0.213 ＞ 0.05. The results of the two non-parameter tests suggested that there was no significant differences in hospitalization evaluation, that is, although the pulse pressure increased obviously in cerebral infarction, the degree of increase had no correlation with the severity of neurological impairment.CONCLUSION: The increase of pulse pressure is related to the occurrence of cerebral infarction and is also an important factor for evaluating cerebral infarction. However, pulse pressure change is not related to the severity of cerebral infarction.

Objective To investigate the correlation between Dishevelled protein expression and the proliferation and invasion of glioma cells.Methods 67 cases of brain glioma specimens were collected.The expression of Dishevelled protein was detected with immunohistochemical method.The immunoreactivity score (IRS) of Dishevelled protein,and proliferation index (PⅠ) and invasion index (Ⅱ) were measured and their correlations were analyzed.Results The positive rate of Dishevelled protein in glioma was 65.7 ％ (44/67).IRS,PⅠ and Ⅱ were 4.15±3.13,(30.93±17.92) ％,(20.38±13.36) ％,respectively.Both PⅠ and Ⅱ significantly increased with an increase in the pathological grade of brain glioma (P ＜ 0.001).Furthermore,PⅠ and Ⅱ were significantly higher in the Dishevelled protein-positive group than those in the Dishevelled protein-negative group [(38.27±17.60) ％ vs (16.02±8.92) ％ of PⅠ and (30.03±13.81) ％ vs (10.63±4.41) ％ of Ⅱ,respectively,P ＜ 0.001].PⅠ and Ⅱ of glioma cells were positively correlated with IRS of Dishevelled protein (r =0.940 between PⅠ and IRS,and r =0.953 between Ⅱ and IRS,respectively).Conclusion Dishevelled protein plays an important role in the proliferation and invasion of brain malignant glioma.

Objective Studies on IMRT technique demonstrates that the improved dose homogeneities throughout the breast as well as reduction in dose to the heart and the ipsi-and control-lateral lungs. Methods Based on the physical principle of rolling tangential technique, a treatment plan for a patient has been planned by using Pinnacle aperture-based inversion software. The rolling tangential IM-beam was pre-determined at each pre-selected gantry angle with normally angle separation of 5?, 10? or 15?. Each beam's width was so chosen that the inner-and outer-edge of the beam should be tangential to the inner chest wall and target outer surface respectively. For the starting and ending tangential beam, a pair of opposing beam was designed. The beam's orientation was suggested to be reversed to its opposite angle when the tangential beam's gantry angle reached 90? or 270?. Each beam's shape and size were adjusted on its BEV map. For each tangential beam, 7 sub-segment beams were chosen for each tangential beam. Then, planning system was allowed to do optimization according to the clinical dose prescriptions. Results The calculated dose distributions in target(CTV), left & right lungs, and heart showed that the volume received the prescribed dose 50?Gy V_ 50 was 0.95; The volume in target enclosed with 95%, 105%, 110%, 115% isodose lines V_ 95% , V_ 105% , V_ 110% , V_ 115% was 0.98, 0.84, 0.53, 0.18, respectively. The volume of V_ 10 ,V_ 20 , V_ 30 , V_ 40 V_ 50 , in the lungs and heart were significantly decreased when compared to the current IMRT techniques published in the literature(Table 1).Conclusions The rolling tangential IM-segment irradiation technique for the breast developed by the author is able to offer not only a better dose distribution and better dose conformity throughout the target, but also reduce significantly the dose to the lungs and heart, with the patient's set up and localization process being very simple. The treatment planning for individual patient is optimal in any treatment planning system with Aperture-Optimization inverse software. This technique is certainly to offer more benefit to the patient if some measures are taken to limit or to follow the movement of the chest wall during irradiation.

Objective To analyze the related factors of carotid atherosclerosis in type 2 diabetes mellitus pa-tients complicated with nonalcoholic fatty liver disease .Methods 288 type 2 diabetes mellitus patients complicated with nonalcoholic fatty liver disease were divided into carotid atherosclerosis group (group A) and non-carotid athero-sclerosis group ( group B ) , according to whether they had carotid atherosclerosis .The related factors of these two groups,such as BMI,blood pressure,blood glucose,blood lipid,liver function were analyzed.Results The two groups had no significant differences in systolic pressure and diastolic pressure (P>0.05).ALT,BMI,HbA1c,FPG,TG,TC, AST of group A were significantly higher than group B [ALT (55.12 ±9.13)mmol/L vs (36.22 ±8.76)mmol/L, BMI (28.48 ±4.69)kg/m2 vs (23.96 ±3.73)kg/m2,HbA1c (8.57 ±1.69)mmol/L vs (7.62 ±1.28)mmol/L, FPG (9.36 ±2.24)mmol/L vs (8.67 ±1.98)mmol/L,TG (2.12 ±0.38)mmol/L vs (1.23 ±0.17)mmol/L,TC (5.56 ±1.25)mmol/L vs (4.31 ±1.09)mmol/L,AST (25.34 ±5.23)mmol/L vs (21.19 ±4.71)mmol/L](t=17.564,8.726,5.163,2.694,8.788,6.894,all P<0.01).The multiple stepwise regression analysis showed that there was a positive correlation between ALT and BMI (r=0.132,P<0.01),a negative correlation between ALT and AST(r=-0.091,P<0.01).Conclusion The level of ALT could be used as a risk index to judge whether the type 2 diabetes mellitus patients complicated with nonalcoholic fatty liver disease had carotid atherosclerosis .

Objective To investigate the application value of pancreatic duct guide wire and transpancreatic septotomy with precutting technique in difficult endoscopic retrograde cholangiopancreatography.Method258 patients who underwent difficult endoscopic retrograde cholangiopancreatography from April 2014 to April 2016 were selected as study subject, 128 patients among them received the technique of pancreatic duct guide wire, the other 130 patients received transpancreatic septotomy with precutting techniques. The success rate, intubation time and incidence of complications were compared between these two methods for cannulation.Result There was no signiifcant difference in preoperative clinical data between the two groups, the success rate did not differ signiifcantly between the two groups (93.75 % vs 93.85 %). Compared with transpancreatic septotomy with precutting techniques group, pancreatic duct guide wire group is less intubation time consuming (5.92 ± 0.69 vs 12.81 ± 3.67) min, the difference was statistically significant (t = -2.27,P < 0.05). 25 patients experienced complications, with 6 cases of acute pancreatitis, 2 cases of biliray tract infection in pancreatic duct guide wire group, and 8 cases of acute pancreatitis, 3 cases of hemorrhage,6 cases of biliray tract infection in transpancreatic septotomy with precutting techniques group. The pancreatic duct guide wire group had a signiifcantly lower incidence of complications (6.25 % vs 13.08 %). the difference was statistically signiifcant (χ2 = 3.27,P < 0.05). The incidence of acute pancreatitis did not differ signiifcantly between the two groups (4.69 % vs 6.15 %).ConclusionsPancreatic duct guide wire and transpancreatic septotomy with precutting techniques both can further improve the success rate of bile duct cannulation with ERCP. The incidence of acute pancreatitis did not differ significantly between two groups. But pancreatic duct guide wire group is less intubation time consuming, and had a significantly lower incidence of complications. Because of the convenience and safety of the pancreatic duct guide wire technique, and the insertion of the pancreatic duct does not increase the risk of postoperative acute pancreatitis. We think that this method is more worthy of Clinical promotion.
