Objective To evaluate the efficacy of chemoradiotherapy in patients with unresectable pancreatic cancer who were previously treated with PTCD.Methods From September 2005 to December 2012,47 unresectable pancreatic cancer patients with obstructive jaundice were enrolled in this study.They were divided into two groups.21 patients received after PTCD chemotherapy or radiation,or chemoradiotherapy.26 patients in support care group received only nutrition,analgesia and other related support treatment.Survival analysis was performed with Kaplan-Meier statistics.Differences in survival between the groups were assessed for statistical significance with the log-rank test.Results The median overall survival time of patients after PTCD was 7.19 months.The median overall survival time of chemoradiation group was 9.07 months,which was higher than that of support care group (5.52 months),P=0.017.12 patients received single therapy (either chemo or radiation),and 9 patients received chemoradiotherapy.The median overall survival times were 8.31 months and 11.15 months,respectively (P =0.325).Conclusions Post PTCD chemoradiotherapy helps prolong the survival time in unresectable pancreatic cancer patients.

Objective To evaluate the method and curative effect of reconstruction with vascularized or nonvascularized autogenous fibular transplantation of radiocarpal joint after en bloc excision of giant cell tumor of distal radius.Methods Seventeen cases with giant cell tumor of distal radius bone were treated by en bloc resection and reconstruction of wrist joint with vascularized or non-vascularized autogenous fibular transplantation.Postoperative wrist joint function and radiographic outcomes were evaluated.Results Seventeen cases were followed up from 2.0 to 5.5 years (average 3.6 years).Three cases were treated by peroneal artery anastomosis and other 3 cases by inferior lateral genicular artery anastomosis.All cases achieved primary healing of incision and the radial average length that was en bloc excised was 7.6 cm.All of the transplanted fibulas were healed well.The bone healing average time of the vascularized fibular graft was 3.7 months,while that of the non-vascularized fibular graft was 7.9 months.No tumor recurrence or lung metastases was observed during the follow-up,but 1 wrist joint was narrowed and another had degeneration of the wrist.After 2 years of surgery,the average range of motion of the wrist joint was as follows:dorsiflexion 47°,flexion 30°,ulnar deviation 23°,radial deviation 14°,pronation 55°,supination 62°.The grip force was from 40％ to 80％ of the contralateral upper limb.The MSTS score averaged 87.6 ％ with 6 excellent,eight good and 3 satisfactory results.Disabilities of the Arm,Shoulder,and Hand (DASH) questionnaire score averaged 3.48.Conclusion The method of autogenous fibular transplantation and reconstruction of radiocarpal joint after en bloc excision of giant cell tumor of distal radius can save the wrist joint function in a certain extent.It is an effective method of the wrist joint function reconstruction and beneficial to bone healing with vascularized transplantation which has less complications.

Objective To study the efficacy of CPT-11 TACE in the treatment of unresectable HCC.Methods A retrospective review was undertaken on unresectable HCC patients receiving doxorubicin transarterial chemoembolization (59 cases) and irinotecan(CPT-11) in 24 cases from May 2003 to November 2011.Survival analysis was performed with Kaplan-Meier statistics.Differences in survival between the two groups were assessed for statistical significance with the log-rank test.Results Overall survival time was significantly longer in patients treated with CPT-11 compared with doxorubicin treated group (21.7 vs 14.5 months,P =0.042).There was no significant difference in time to progression between the two groups,but time to progression was longer in CPT-11 group than doxorubicin treated group (11.42 vs 9.46 months,P =0.091).Subgroup analysis showed that for intermediate-stage HCC,CPT-11 resulted in a significantly longer time to progression and overall survival compared with doxorubicin treated group (P =0.029 and P =0.014,respectively).There were no significant differences in adverse events among the two groups (P ＞ 0.05).Conclusions Chemotherapeutic agent CPT-11 in the form of TACE significantly improved overall survival when compared with doxorubicin for the treatment of unresectable HCC.

Background:Gastric cancer is one of the malignant tumors with highest morbidity and mortality,and the early change of molecular marker in gastric mucosal lesion is the hot spot of gastric cancer study. Aims:To investigate the expressions and clinical significance of trefoil factor 2(TFF2),claudin 18(CLDN18),mucin 5AC(MUC5AC)in gastric mucosal lesions. Methods:Gastroscopy biopsies and surgery specimens from Dec. 2008 to May 2009 at Inner Mongolia People’s Hospital were collected,including 20 normal gastric mucosal tissues,20 intestinal metaplasia tissues,11 dysplasia tissues and 20 gastric cancer tissues. The protein expressions of TFF2, CLDN18, MUC5AC were determined by immunohistochemical SP method. Results:The positive expression rates of TFF2,CLDN18 and MUC5AC in normal gastric mucosal tissues were all 100% ,and were gradually decreased in the order of intestinal metaplasia,dysplasia and gastric cancer tissue,the differences were statistically significant(P < 0. 01). Conclusions:Expressions of TFF2,CLDN18 and MUC5AC protein are closely related to the degree of malignancy of gastric mucosal lesions,and can be considered as a potential biological marker for predicting the development and prognosis of gastric cancer.

Objective To study the efficacy and safety of high intensity focused ultrasound (HIFU) treatment for advanced pancreatic cancer.Methods In this study,25 patients with advanced pancreatic cancer received high-intensity focused ultrasound (HIFU) treatment.Liver and kidney function,CA19-9 levels,tumor size changes,pain relief,survival rate before and after treatment were evaluated.Results The blood routine test,liver and kidney function,blood amylase did not alter significantly after HIFU treatment in all patients.The CA19-9 level of 12 patients decreased.The appetite of 15 patients improved,5 patients with body weight gain after HIFU treatment.Pain was relieved after HIFU treatment in 18 cases,pain relief rate was 72％ (18/25).In 15 cases tumor ablation volume ＞ 90％ after HIFU treatment,5 patients with tumor ablation volume ＞ 50％,tumor ablation effective rate was 80％ (20/25).There were no major complications such as acute pancreatitis,gastrointestinal injury after HIFU treatment.After HIFU treatment,the median survival period was 8 months,1 year survival rate was 30％.Conclusions High-intensity focused ultrasound is a safe and effective method of palliative treatment for advanced inoperable pancreatic cancer.

Objective To study the efficacy and the safe dosage of high intensity focused ultrasound (HIFU) ablation in pancreatic cancer.Methods From November 2010 to May 2013,21 patients with advanced pancreatic cancer were treated by HIFU at the First Affiliated Hospital of Zhengzhou University.These patients who were randomly divided into two groups (10 and 11 patients respectively),were given a low-power (100～249 W) treatment and a high power (250 ～350 W) treatment.These two groups of 21 patients received a total of 25 times of HIFU treatment (3 patients received twice of low-power treatment,while 1 patient received twice of high-power treatment).The two groups were compared by analyzing the treatment parameters (average power,total treatment time,treatment total energy,treatment volume,etc.) and volume of tumour response as shown on postoperative imaging (CT or MRI) examinations.Also,the complications,degree of pain relief and survival were compared.The energy efficiency factor (EEF) and the ablation ratio were calculated.A preliminary study was conducted on the relationship of the ultrasound dose and the ablation effect of HIFU treatment for pancreatic cancer.Results (1) The EEF of the high-power group (≥250 W) and the low-power group (＜ 250 W) were (10.39 ± 5.71) J/mm3 and (21.62 ± 9.81) J/mm3,the former group was significantly lower than the latter group (P ＜0.05) ; the ablation ratio of the high-power group was higher than the low-power group,(91.52 ± 4.18)％ versus (51.59 ± 7.66)％ respectively,the difference was statistically significant (P ＜ 0.001).(2) The efficiency factor and the ablation volume for the HIFU treatment showed a linear trend,and both were negatively correlated (Pearson correlation coefficient r =-0.485,P ＜ 0.05).(3) There was no serious complication after the HIFU treatment.In the low-power group,six of ten patients were alleviated of his pain (60％) ; the CA19-9 decreased in four of ten patients after HIFU treatment (40％).In the high-power group,nine of eleven patients were significantly relieved of pain after treatment (82％),the CA19-9 decreased in five of nine patients after HIFU treatment (56％).(4) On Kaplan-Meier survival analysis,HIFU treatment of patients with pancreatic cancer,the median survival was 8 months and 9 months in the low-power group and high power group,respectively (Log-rank test x2 =0.05,P =0.944).Conclusion During HIFU treatment of patients with pancreatic cancer,if the ultrasound power was between 250 W and 350 W,there was a higher proportion of tumor ablation,but with no serious complications.Thus,this dose was safe.

Objective To investigate the procedures and effects of surgical treatment for double disruption of the superior shoulder suspensory complex (SSSC).Methods Twenty-nine cases of double disruption of SSSC treated from January 2007 to October 2011 were enrolled in the study.There were 19 males and 10 females,at a mean age of 36 years (range,25-49 years).Injury causes included traffic injury in 25 cases and fall from height in 4.An open reduction and internal fixation was performed in 18 cases of scapular neck fracture combined with clavicular fracture,2 cases of scapular neck fracture combined with acromion fracture,2 cases of distal clavicular fracture combined with acromion and glenoid cavity fracture; hook plate fixation and ligament repair were performed in 3 cases of complete dislocation of acromioclavicular joint combined with complete disruption of coracoclavicular ligament ; open reduction and internal fixation and ligament repair were performed in 3 cases of scapular neck fracture combined with acromioclavicular joint dislocation and 1 case of clavicular fracture combined with coracoclavicular ligament disruption.Results All cases were followed up for a mean period of 11.5 months (range,6-30 months).Anatomic reduction of fractures was achieved for all cases and mean healing time was 8.4 weeks (range,7-12 weeks).Mean Constant-Murley score was 91 points (range,72-100 points),which indicated excellent results in 13 cases,good in 11,fair in 5,with excellence rate of 83％.ConclusionBased on the complex anatomic structure of the double disruption of SSSC,surgical management should focus mainly on respective fixation of the double injuries,which leads to good stability and therapeutic outcome.

Compared with living spray method, it focused on the investigation of different inoculation methods, various inoculation concentration and the influence of different seeding age on soft rot-resistance in Jinxianlian. The results showed that (1) Inoculated with dropping connection, the difference of disease index between A. roxburghii and A. formosanus was grate, so that the disease-resistance could be obviously distinguished. (2) When the inoculation concentration was 1.0 x 10(7) cfu x mL(-1), the difference of disease index was relatively obvious and the disease-resistance could be differentiated well. (3) At the moment of 4-month seeding inoculation, a certain difference of the disease index between A. roxburghii and A. formosanus was existed, so, relatively, it could accurately reflect the resistance difference between various species. With the inoculation of dropping connection, A. roxburghii and A. formosanus of 4-month seeding age was put in the bacteria suspension of inoculation concentration of 1.0 x 10(7) cfu x mL(-1). The identification was taken up after 5 days in the incubator under the condition of 14 h daylight and 28 degrees C. The identification result was conformed with that of the living spray method. To investigate the identification method of in vitro evaluation of soft rot-resistance of Jinxianlian so as to provide the foundation for germplasm utilization and excellent cultivars breeding.
