Objective To investigate the expressions of CYCLIND1 CDK4 in pancreatic cancer and their relationship with clinlicopathological parameters.Methods Immunohistochemical detector with new second generational tow steps method was used to detect the expressions of CYCLIND1 CDK4 and PCNA in 48 cases of pancreatic cancer and 14 cases of chronic pancreatitis.Results The expressions of CYCLIND1 CDK4 proteins in pancreatic cancer were 70.85%(34/48)and 62.50%(30/48) respectively.The CYCLIND1 and CDK4 proteins were increased(P

Objective To discuss the effect of hemodilution on brain tissue oxygen pressure and prognosis in patients with severe craniocerebral trauma. Methods A total of 42 cases of severe craniocerebral trauma were randomized divided into two groups, ie, control group and treatment group, to observe the changes of brain tissue oxygen pressure ( PbtO2 ) , hematocrit (HCT) and 6-month Glasgow outcome scale (COS) after injury. Then, PbtO2, HCT and GOS were compared between two groups. Restilts ( 1 ) There was a positive correlation between PbtO2 and HCT when HCT was lower than 0.25( r =0. 732 ,P ＜0. 001 ) in the treatment group; while a negative correlation was found between PbtO2 and HCT when HCT was higher than 0.25(r = - 0. 698 ,P＜0. 001 ). (2) Compared with control group, the index of brain tissue oxygen in treatment group was obviously higher ( t = 2.27, P = 0. 029 ) , with better prognosis (X2= 5.09, P ＜ 0.05 ). Conclusion Hemodilution can significantly increase brain tissue oxygen supply and improve the prognosis of cases of severe craniocerebral trauma.

Objective To observe the pathological changes of tissues of the injured bile duct, and to provide theoretical basis for bile duct repair. Methods Dog models of obstructive biliary injury were established.Sixty dogs were equally divided into five groups according to the duration of biliary obstruction: biliary obstruction for 5 days (BDL5 group), 10 days (BDL10 group), 15 days (BDL15 group), 20 days (BDL20 group) and 30 days (BDL30 group). The morphological and pathological changes of bile duct and local tissues were observed, and biliary-enteric Roux-en-Y anastomosis was applied to repair the injured bile duct and postoperative complications were observed. All data were analyzed by LSD test, independent sample t test, one-way analysis of variance and chi-square test. Results Proximal bile duct rapidly expanded as the pressure increased in the early stage, and the bile duct expanded to ( 15.6 ± 1.8)mm in the BDL10 group. The expansion rate decreased in the later stage,and the bile duct expanded to (18.9 ± 1.9)mm in the B DL15 group. Acute inflammation was observed in injured local tissues. The acute inflammation was severe in the BDL5 group with white blood cell count of 54 ± 6, and the acute inflammation was relatively mild in the BDL15 group with white blood cell count of 42 ± 7. There was a significant difference between the BDL5 group and BDL15 group in the degree of acute inflammation (t =4. 688,P ＜ 0. 05). The content of the collagen was increased in the injured bile duct as time passed by. Bile duct repair was successfully performed on 57 dogs. Ten dogs ( three in the BDL5 group, four in the BDL10 group, one in the BDL15 group, one in the BDL20 group and one in the BDL30 group) died of bile leakage after the operation. The incidences of bile leakage was 30% (7/23) within 10 days and 9% (3/34) beyond 10 days, with a significant difference between the two groups (x2 =4.429, P＜0.05). Conclusion Ten days after obstructive biliary injury,an obvious reduction of bile duct expansion and edema of the bile duct is observed, the difficulty of the operation is reduced and the incidence of bile leakage is low, so 10 days after the incidence of obstructive biliary injury is the proper timing for the surgical repair.

Objective To investigate the effects of noise from the subway cars on the preferred listening volumes using different kinds of earphones.Methods A total of 75 subjects with normal hearing were investigated to listen the same song wearing 4 kinds of earphones: insert earphones, intra-concha earphones, supra-concha earphones, and circumaural earphones, in the semi-anechoic background and inside the Line 7 subway-cars of the Beijing subway (the mean of LAeq,1s is 80.3 dB A and then selected personally preferred listening volumes.The effects of noise in the subway cars and earphone types on the preferred listening volumes were then analyzed.Results Inside subway-cars, the preferred listening levels using insert earphones, intra-concha earphones, supra-concha earphones, circumaural earphones were 76.6±4.7, 84.3±5.0, 82.3±4.2, and 80.8±4.2 dB A, respectively.The levels were respectively 65.5±6.8, 71.9±7.1, 69.5±7.5, 67.9±7.3 dB A for those in the semi-anechoic background.The preferred listening levels increase more than 10 dB averagely when stepped into noisy subway-cars background from silent background.According to the threshold levels stipulated in the WHO, to avoid hearing impairment, the daily noise exposure duration should not exceed 134 mins when exposed to subway-cars noise and the duration should not exceed 315, 54, 85, and 120 mins respectively when wearing those 4 kinds of earphones in subway-cars.Conclusion The noise and earphones types have great effects on the preferred listening volumes.The noise exposure levels in the ear canal wearing earphones with good sound insulation and listening at highly increased volume may be lower than that without earphones.

Objective To study the feasibility of video-assisted thoracoscopic (VAT) minor pulmonary resection under local anesthesia. Methods From February to December 2000,8 patients (6 cases of peripheral pulmonary nodules,2 cases of respiratory insufficiency and radiographic pulmonary infiltrate)were operated on through video-assisted thoracoscopy under local anesthesia. Results Except 1 case was converted to general anesthesia and performed minithoracotomy to resect pulmonary coin lesion due to pleural adhesion,other 7 patients underwent VAT-pulmonary wedge ressction under local anesthesia and definitive diagonosis.(3 with tuberculosis,1 with metastatic adenocarcinoma,1 with inflammatory pseudotumor and 2 with pulmonary fibrosis)were obtained.The duration of the procedures was from 40 to 200 min. Spontaneous breathing and hemodynamics were maintained well during the operation.There was neither severe postoperative complications nor mortality.The postoperative hospitalized days were 2～5 days with a mean of 3 days. The average medical fee for pulmonary wedge ressction using our procedure was 5400 RMB. Conclusions VAT-minor pulmonary resection can be performed safely under local anesthesia.
