Objective To investigate the role and value of the biliary stent in the treatment of large common bile duct stones. Methods Thirty-two patients with large common bile duct stones were underwent plastic biliary stenting after endoscopic stone extraction with oddi sphincterotomy, and were followed up for 6 months. Results Thirty-two patients were successfully placed biliary stents. The postoperative jaundice, abdominal pain and other symptoms were alleviated. The secondary endoscopic retragrade cholang iopancreatography (ERCP) was performed six months after surgery. Large stones disappeared in 3 cases, 25 cases were reduced to varying degrees, 4 cases showed no obvious narrowing in 32 patients with biliary stones. Twenty-nine patients with residual stones were taken stone again. The operation was successful in 25 cases . Four cases continued to be observed the drainage of biliary since the difficulties for taking stone. The success rate of treatment of large common bile duct stones by biliary stent was 87.5%. Conclusion The therapy of large common bile duct stones by biliary stent is of simple, short operation time, fewer complications, satisfactory results, safe and effective advantages.

Objective To study the methods of repairing the sole defects and reconstruction of the sensory function. Methods Twenty- nine cases of sole defect were repaired with flaps and full- thickness grafting according to the weight- bearing area and non- weight- bearing area. Sixteen cases had reconstruction of the sensory nerves. Results Twenty- nine cases were followed up for 1－ 9 years. One case failed. One case required thinning the flap. Twenty- eight cases have gained normal weight bearing ambulation. Ulcer occurred in one case, giving an ulcer rate of 3.4％ . The sensation have recovered to S2－ S3 in 16 cases repaired with reconstruction of cutaneous sensory nerves. Thirteen cases repaired with non- innervated flaps and full- thickness grafting showed deep pain sensation, and over the 1－ 2 cm area coverage around the flaps there was light touch sensation. No significant difference was found in the ulcer rate between reinnervated and non- innervated flaps. Conclusion Defects of the weight- bearing area in sole must be repaired with flaps. The medial foot island flap, medial pedal island flap, toe arterial flap and anterolateral thigh flap are the appropriate options. Defects of the non- weight- bearing area could be repaired with full- thickness grafting. The transplantation of non- sensory skin flaps can re- establish the sensory function, so the reconstruction of sensory nerve is of minor importance.

Objective To investigate the correlation of Ureaplasma urealyticum (UU ) infection and human papillomavirus (HPV) infection .Methods 348 outpatients in the obstetrics and gynecology clinic of our hospital were performed the retrospective analysis .The cervical secretion samples were collected and simultaneously detected the common high risk types of HPV DNA (16 , 18 ,31 ,33 ,45 ,52 ,56 ,58) and UU DNA by using fluorescence quantitative PCRAB7300 detecting instrument .The two groups of da‐ta were set .In the first group ,UU DNA positive was taken as the experimental group and UU DNA negative as the control group , the data in the two groups were performed the detection positive rate analysis of common high‐risk HPV DNA .In the second group of data ,UU DNA copy number greater than 104 was taken as the positive control and UU DNA copy number less than 104 as the negative control ,two groups of data were performed the detection positive rate analysis of common in high‐risk HPV DNA .Results In the first group of data ,the UU DNA detection rate reached 67 .5 (235/348) ,the HPV DNA detection rate with UU positive was 14 .89% (35/235) ,while which with UU negative was 7 .07% (8/113) ,the difference between the two groups of data had sta‐tistically significant(χ2 =4 .302 3 ,P<0 .05) .In the second group of data ,the HPV detection rate with UUDNA copy number grea‐ter than104 was 17 .75% (30/169) ,while which with UU DNA copy number less than 104 was 7 .57% (5/66) ,the difference be‐tween the two groups of data was statistically significant (χ2 =3 .877 3 ,P<0 .05) .Conclusion UU infection has a correlation with HPV infection ,UU infection will increase the probability of HPV infection ,moreover with UU content increase ,the HPV infection is increased .

Objective To study the relationship between parameter settings in the intensity-modulated radiation therapy (IMRT) planning in order to explore the effect of parameters on absolute dose verification.Methods Forty-three esophageal carcinoma cases were optimized with Pinnacle 7.6c by experienced physicist using appropriate optimization parameters and dose constraints with a number of iterations to meet the clinical acceptance criteria.The plans were copied to water-phantem,0.13 cc ion Farmer chamber and DOSE1 dosimeter was used to measure the absolute dose.The statistical data of the parameters of beams for the 43 cases were collected,and the relationships among them were analyzed.The statistical data of the dosimetry error were collected,and comparative analysis was made for the relation between the parameters of beams and ion chamber absolute dose verification results.Results The parameters of beams were correlated among each other.Obvious affiliation existed between the dose accuracy and parameter settings.When the beam segment number of IMRT plan was more than 80,the dose deviation would be greater than 3％ ; however,if the beam segment number was less than 80,the dose deviation was smaller than 3％.When the beam segment number was more than 100,part of the dose deviation of this plan was greater than 4％.On the contrary,if the beam segment number was less than 100,the dose deviation was smaller than 4％ definitely.Conclusions In order to decrease the absolute dose verification error,less beam angles and less beam segments are needed and the beam segment number should be controlled within the range of 80.

ObjectiveTo measure the setup errors with infrared marker-based positioning system (IM-BPS) and electronic portal imaging device (EPID) for patients with esophageal carcinoma and lung cancer and investigate the accuracy and practicality of IM-BPS. MethodsFrom January 2007 to January 2008, 40 patients with esophageal carcinoma and 27 patients with lung cancer received three-dimensional conformal radiotherapy or intensity-modulated radiotherapy, setup errors during the treatment were measured with IM-BPS and EPID, and the data of setup errors were compared with paired t-test and agreement with x2-test. ResultsIt takes 10 - 12 mins to complete the validating for each patient by EPID) system, while IMBPS system only needs 2 -5 mins. The mean setup errors along x, y and z-axis for patients with esophageal carcinoma measured by IM-BPS and EPID were 3.49 mm, 3. 19 mm, 3.31 mm and 4. 03 mm, 3.41 mm, 3.43 mm, respectively. For the patients with lung cancer, the setup errors were 4. 23 mm, 3.51 mm, 3. 39mm and 4. 85 mm, 3. 53 mm, 3.74 mm, respectively. The difference of setup errors meanured by the two systems was within 1 mm for 65％ esophageal carcinoma patients ( x2 =51.09, P =0. 000), and 55％ lung cancer patients ( x2 =53. 35, P =0. 000).Conclusions The measurement results of setup errors for patients with esophageal carcinoma and lung cancer show that IM-BPS is mostly better than EPID. Though validating for patients can be measured accurately and be well quality controlled, IM-BPS is used easily because of macroscopic, homely,spare time and real-time monitoring.

Objective:To analyze the factors affecting lymph node failure pattern after radiotherapy/chemotherapy in esophageal squamous cell carcinoma without initial clinical metastasis. Methods:A total of 263 patients, who were diagnosed as thoracic esopha-geal carcinoma from January 2002 to December 2009, were included in this retrospective study. Factors affecting lymph node failure pattern with general clinical data and tumor local factors were analyzed. Results:Among the 263 esophageal cancer cases, 31 (11.8%) had lymph node metastasis after treatment, including 18 cases of simple lymph node metastasis and 13 other cases of lymph node metas-tasis with esophageal and other organ metastasis or recurrence. The numbers of cases for lymph node metastasis in the upper, middle, and lower thoracic esophagus were 11 (13.3%), 13 (10.1%), and 7 (13.7%), respectively. Univariate analysis showed that recent cura-tive effect, length of tumor on X-rays, maximum tumor diameter, and tumor volume were the significant factors associated with lymph node metastasis (χ2=7.597, 9.717, 5.361, and 4.815;P=0.006, 0.002, 0.021, and 0.028). Logistic regression analysis results showed that recent curative effect and length of tumor on X-rays were independent significant factors (P=0.004 and 0.026). Conclusion:Recent cu-rative effect and length of tumor on X-rays were the significant factors associated with lymph node failure pattern after radiotherapy/chemotherapy in esophageal squamous cell carcinoma without initial clinical metastasis.
