Objective To explore the clinical characteristics of evolutionary type of traumatic subdural hydroma(ETTSH) and experiences of diagnosis and treatment of ETTSH. Methods The clinical data of 37 patients with ETTSH were analyzed retrospectively. Results The patients ages were from 3 months to 75 years old, most of primary craniocerebral injuries were mild, the main clinical manifestation was chronic increased intracranial pressure, and the final diagnosis time by CT scanning was 28 to 110 days after craniocerebral injury. All patients had a good prognosis by surgical drainage. Conclusion Polarized age, mild primary craniocerebral injury and chronic increased intracranial pressure are the main clinical characteristics of ETTSH. Dynamic CT scanning and surgical drainage were the first choice of diagnosis and treatment of ETTSH, respectively.

Hilar cholangiocarcinoma is a type of malignant tumor of the extrahepatic ductal system.Due to hepatic artery and portal vein involvement within the liver hilum,the resection rate is low and the prognosis is poor.However,with several advances in imaging technology achieved during the last decades,the accuracy of diagnosing and assessing the resectability of hilar cholangiocarcinoma has been greatly improved.In fact,some new classification and staging systems have been proposed to evaluate the tumor.This review will discuss the recent advances in the classification,staging,and preoperative resectability assessment for hilar cholangiocarcinoma.

Objective To investigate the abnormal situation and the characteristics of body mass index(BMI),blood pressure (BP),blood lipid(BL),and fasting plasma glucose(FPG) in residents of Chongqing.Methods Data of BMI,BP,BL and FPG were obtained from 16 367 residents receiving regular health examination in our Hospital in 2006.Results These metabolic indicators of this group were abnormal:The detection rate was 33.2%(42.5% in male and 17.6% in female)for overweight;7.4%(9.7% in male and 3.5% in female) for obesity;25.4%(30.0% in male and 17.6% in female) for hypertension;,38.9%(41% in male and 35.5% in female) for total cholesterol;26.1%( 34% in male and 12.8% in female) for triglyceride;23.7%(26.8% in male and 18.6% in female) for low-density lipoprotein;8.2%(11.8% in male and 2.2% in female) for high-density lipoprotein;3.2%(3.8% in male and 2.2% in female) for impaired fasting glucose;and 3.2%(3.9% in male and 2.0% in female) for diabetes meUitus.The detection rate of these metabolic disorders was significantly higher in men than those in women,and increased with age,which was significantly higher in people aged 30-40 years than in people aged less than 30 years.Conclusion The levels of BMI,BP,BL and FPG of health examination residents in Chongqing had its unique characteristics,and were abnormal significantly,it was very important to take regularly health examination after 30 yrs old.

AIM To explore the reversal effect of multidrug resistance (MDR) and the influence on topoisomerase (TOPO) activity by emulsion of seed oil of Bbrucea Javanica (ESOBJ) in vitro . METHODS Cytotoxic effects of ESOBJ against sensitive and resistance tumor cells were deter mined by MTT assay. Influences of ESOBJ on the catalytic activities of TOPO Ⅰ and TOPO Ⅱ were measured by TOPO Ⅰ mediated negatively super coiled pBR322 relaxation and TOPOⅡ mediated kDNA decatenation. RESULTS 0 025 g?L -1 of ESOBJ could reverse MDR in various MDR cell lines such as K562/A02?MCF 7/ADM and KB/VCR. DNA TOPO Ⅱ mediated kDNA decatenation experiment showed marked inhibitory action of ESOBJ on TOPO Ⅱ activity at the concentration of 0 31 g?L -1 and TOPO Ⅱ activity was totally inhibited by ESOBJ at the concentration of 2 5 g?L -1 . On the other hand, ESOBJ exhibited no influence on DNA TOPO I mediated pBR322 relaxation and on DNA directly. CONCLUSION ESOBJ could reverse MDR to a certain extent in vitro , and inhibit the activity of TOPO Ⅱ significantly.

Objective To analyse the clinical characteristics,gene mutation and enzymatic activity of αgalactosidase A(α-GalA)in a 15-year-old male patient with typical Fabry disease,whose mother was without any clinical manifestations.Methods Clinical features and laboratory data were collected from the patient and his mother.Genomie DNA was extracted from peripheral blood of the patient.his mother,and a healthy control subject.Seven exons of the GLA gene were amplified by PCR.PCR products were purified.cloned into T vector,and then sequenced.The enzymatic activity of α-GalA Was measured by fluorimetrie substrate assay. Results DNA sequencing results showed that a missense mutation of 10036-10038delAAG in exon 7 WaS identified in the patient,resulting in the replacement of 374 lysine and 375 glyeine by arginine,which Was not previously reported.The patient Was a hemizygote with gene mutation,his mother WaS a heterozygote carrying gene mutation,and the healthy control without mutation.α-GalA enzymatic activity assay showed that the enzymatic activity of the patient with GLA gene mutation was only 50%of the healthy control subject,while the enzymatic activity of the patient's mother Was about 70%of the heahhy control SObject.Conclusiolls Detecting GLA gene mutation and α-GalA enzymatic activity in patients with Fabry disease who have been clinically diagnosed seelns to be helpful in finding other patients in the family and in further understanding the molecular pathogenesis of that disease.

Objective To explore the effectiveness and safety of endoscopic papillary balloon dilation( EPBD ) for the removal of common bile duct stones. Methods Three hundred and twenty consecutive patients with common bile duct stones on endoscopic retrograde cholangiopancreatography (ERCP) who met all eligibility criteria were randomly assigned endoscopic sphincterotomy (EST) or EPBD.Complications were classified by an expert panel unaware of treatment allocation and outcome. Results After a single ERCP, all stones were removed from 112 patients ( 70% ) assigned EST and 104 ( 65% )assigned EPBD. Mechanical lithotripsy was used to fragment stones in 36 (22. 5% ) EPBD procedures and 32 ( 20. 0% ) EST procedures. Early complications occurred in 5.6% EST patients and 8.1% EPBD patients. No patient died. Gallstone disease recurrence, which is a long-term complication, is 7. 5% ( 12/160) in EST patients and 2.5% (4/160) in EPBD patients, P ＜0. 05. Conclusions The success rate of EPBD was similar to that of EST. We found no evidence of previously suggested higher risk of pancreatitis with EPBD, and suggest that EPBD is preferred in patients who are not suitable for EST, such as those with high risk of bleeding. This procedure is a valuable alternative to EST in patients with bile duct stones.

Objective To identify the compliance and influencing factors of colorectal cancer screening among urban communities. Methods People in urban communities are categorized as the case group, comparison group A and comparison group B, according to whether they receive questionnaire survey, FOBT test, intestine mirror, and different follow-up results in this screening test Results No significant differences (P>0.05) are found among people from different groups. In the survey for screening related knowledge, understanding of such knowledge is significantly higher than the comparison group(P>0.01), and the knowledge of comparison group A is higher than that of comparison group B. Conclusion The higher their knowledge in screening, the higher their compliance for screening.

Objective To discuss the relationship between prognosis and different surgical procedures for gallbladder cancer in different stages. Methods The clinical data of 107 patients with gallbladder cancer from January 2001 to May 2007 were retrospectively analyzed. The surgical procedure was chosen according to different stages. Results Eighty-one of the 107 patients (75.6%) were followed up with the median time of 5 years. Of the 10 patients with stage Ⅰ gallbladder cancer who had underwent simple cholecystectomy, 9 survived. Of the 8 patients with stage Ⅱ gallbladder cancer, 3 received palliative cholecystectomy and the median survival time was 12 months, which was significantly shorter than 24 months of the remaining 5 patients who received radical operation (X2= 5.698, P <0.05). Of the 42 patients with stage Ⅲ gallbladder cancer, 18 received radical operation, and the median survival time was 24 months, which was not significantly different from 18 months of the 5 patients who received extended radical operation (X2=0.238, P>0.05). The remaining 19 patients received palliative operation, and the median survival time was 6 months, which was significantly shorter than those of patients received radical operation or extended radical operation (X2=5.772, 6.318, P <0.05). There were 47 patients with stage Ⅳ gallbladder cancer. Seventeen patients received extended radical operation and 30 received palliative operation, and no significant difference upon the median survival time was observed among different surgical procedures (X2=0.001,0.694, P>0.05). The complication recurrence after the extended radical operation was significantly higher than palliative operation (X2=6.039, P<0.05). Conclusions For patients with stage Ⅰ gallbladder cancer, simple cholecystectomy is preferred. Radical operation is good for patients with stage Ⅱ gallbladder cancer. The choose of radical operation or extended radical operation for patients with stage Ⅲ gallbladder cancer should be based on the condition of invasion. Palliative operation could be used to patients with stage Ⅳ gallbladder cancer.
