Few studies of cetuximab on patients with gastric and esophageal cancer were available now.The disease control rate was 72.7%～92%,OS was 9.5～16.6months,PFS/was 6.2～11 months among first-line setting with cetuximab-contained regimens.And cetuximab shown in second-line regimen setting overcome the resistance of irinotecan and docetaxel.The pCR was 13%～65% when cetuximab was used as induction treatment combined with concurrent chemoradiation.18F-FDG-PET was a potential method to predictthe efficacy of cetuximab-contained regimens,however,status of Kras gene had no predictive value.

Objective To study the value of CT and MRI(3D heavy T_2WI) in cerebrospinal fluid rhinorrhea.Methods 4 cases with spontaneous cerebrospinal fluid (CSF) rhinorrhea confirmed by operation were collected in this study.There were 2 men and 2 women.All patients underwent CT thickness was 0.625 mm and no gaps.MRI (coronal 3D heavy T2WI,thickness of 1 mm,TR/TE 5000 ms/119 ms).Results All 4 cases accepted the treatment of operations.The defects bone were showed by CT,and the sign of CSF of intracranial cavity communicated with nasal cavity diretly was showed by MRI,pituitary herniated into sphenoid sinus in one case also showed by MRI.Conclusion For spontaneous cerebrospinal fluid rhinorrhea,thin-section coronal CT scan and MR coronal 3D heavy T_2WI can clearly show the location of fistulas.

Objective To analyze the etiological factor for hypo-side agglutination in cross match blood test(CMT)with microcolumn gel assay,and to provide a guide to the clinical blood transfusion.Methods The data were collected and analyzed about 81 cases with hypo-side agglutination in CMT with microcolumn gel assay and direct antiglobulin test(DAT)positive from Jan.2007 to Oct.2008.Results Among the 81 hype-side agglutinated cases,most were with kidney disease,liver and gall disease,hematologic disease and immunologic disease.Specially,the kidney disease was most,accounting for 16.2%.Conclusion The analysis contributes to disposal in CMT and the safety of clinical blood transfusion.

Objective To observe the efficacy of Foley balloon combining with uterine adhesions to prevent the recurrence of intrauterine adhesions after resection of intrauterine adhesions.Methods Patients underwent resection of intrauterine adhesions were randomized into two groups. 30 patients in control group underwent the therapy of uterine adhesions to prevent the relapse intrauterine. On the other hand, the study group with 30 patients were placed Foley balloon for 5 ~ 7 days and combined with the therapy of uterine adhesions to intervention for 1 ~ 2 weeks. All patients were followed-up for 1 ~ 2 months, and the result of the intrauterine adhesion were assessed by hysteroscopy.Results The rate of the relapse in control group was 3.33%; the study group had the same result (the rate was 3.33%). There was no difference between these two groups.Conclusions The rate of recurrent intrauterine adhesions is no different between the control group of only use therapy of uterine adhesions and replacement of Foley balloon combining with therapy of uterine adhesions as intervention.

Objective To investigate the clinical feature on pulmonary complications after renal transplantation,in order to provide the evidence of prevention and treatment of pulmonary complications.Methods The clinical data of 125 renal transplant re-cipients in the First Affiliated Hospital of Chongqing Medical University from December 2006 to December 2011 were studied retro-spectively.To analyze and summarize the clinical characteristics of postoperative pulmonary complications including the incidence, the time of onset,etiology or risk factors,treatment,outcome,et al.Results Twenty-three patients(18.4%)developed pulmonary complications after renal transplantation.The most frequent complication was pulmonary infection(n = 22,17.6%),followed by pleural effusion(n=12,9.6%),pulmonary edema(n= 7,5.6%),respiratory tract bleeding(n=4,3.2%),acute lung graft versus host reaction(n=1,0.8%)and atelectasis(n= 1,0.8%).Conclusion Pulmonary infection,pleural effusion and pulmonary edema are common pulmonary complications after renal transplantation.Patients who develop pulmonary infection and pulmonary edema have a poor prognosis.

Objective]To explore the experiences in syndrome differentiation and treatment of acute leukemia from chief physician Xia Xiaojun. [Metheod] Learning my teacher diagnosing the disease, I refer to literature and combine with the study to summarize and introduce my teacher's clinical experiences and academic point of view in treatment of acute leukemia from the etiology and pathogenesis, syndrome differentiation, treatment, prescriptions and so on. [Results]Teacher Xia thinks that the emphasis of acute leukemia is deficiency in origin and excess in superficiality.The treatment is replenishing qi and blood,enforcing spleen and nourishing kidney and detoxication and activating blood stasis.Weighing the illness samples priorities and distinguishing between primary and secondary so as to improve the curative effect.[Conclusion]Teacher Xia bases on the progress of acute leukemia in different stages of syndrome characteristics,combines traditional Chinese with western medicine and finds the Huisheng Decoction series hebal medicine for treatment according to syndrome differentiation.The clinical curative effect is remarkable and the knowledge is worthy of our further in-deep learning.

BACKGROUND:Cartilage scaffold plays an important role in articular cartilage injury, but it is stil restricted in practice, leading to the repair failure using tissue-engineered cartilage. OBJECTIVE:To explore the preparation method of cartilage scaffold with directional structure and its repairing effect in cartilage injury of rabbits. METHODS:Directional cartilage scaffolds were prepared by temperature gradient induced phase separation technique. The cross-linking of cartilage scaffold was completed with genipin. The physical and mechanical properties of scaffolds were determined. Forty-eight white rabbits were modeled into exercised-induced articular cartilage injury and equivalently randomized into two groups, fol owed by implantation of non-directional or directional scaffolds. Samples were col ected at postoperative 6, 12 and 24 weeks to compare the repair effect of two scaffolds on rabbit joint injury. RESULTS AND CONCLUSION:Scanning electron microscope showed that the regular microstructures on the longitudinal section of directional scaffolds were aligned in the same direction, while the longitudinal and transverse planes of the non-directional scaffolds showed porous honeycomb structures. The elastic modulus of the directional scaffold was significantly higher than that of the non-directional scaffold (P<0.05). O’Driscol histological scores in the directional scaffold group were significantly higher than those in the non-directional scaffold group at 6, 12 and 24 weeks postoperatively (P<0.05). At postoperative 24 weeks, in the directional scaffold group, the three-dimensional reconstruction of the rabbit defect region was flat and smooth, and coronal two-dimensional scanning showed the cartilage thickness of the newborn cartilage was very close to that of the normal bone;the cartilage surface in the non-directional rabbits was flat under three-dimensional CT, and coronal two-dimensional scanning showed that the repaired cartilage was almost the same as the normal cartilage. Hematoxylin-eosin staining showed that at 24 weeks postoperatively, the defect site disappeared and the cartilage cel s arranged in the vertical direction in the directional scaffold group. There were typical cartilage lacunae at the defect site in the non-directional scaffold group at 24 weeks postoperatively. Our findings suggest that the directional cartilage scaffold prepared using temperature gradient induced phase separation technique holds good physical and mechanical properties, and its implantation into the rabbit articular cartilage injury induced by exercise can promote the injury repair to obtain ideal mechanical properties.
