With the improvement of endoscopic technology,an increasing number of early esophageal cancer is diagnosed by gastroscopy.Regardless of the size or submucous fibrosis of esophageal cancer,endoscopic submucosal dissection (ESD) allows en bloc resection and histologically complete resection of the tumor.ESD has been recognized as an optimal treatment modality for early esophageal carcinoma.Currently,short-term curative effects of early esophageal cancer after ESD have been proved satisfactory,but the long-term outcomes remain unclear.This paper reviews the research advances about the long-term outcomes of ESD,and focuses on the postoperative stenosis,the recurrence,metastasis and survival rates of patients,to provide treatment reference for clinicians.

Objective To observe the clinical efficacy of electroacupuncture plus puncturing the thirteen ghost points in treating diabetic gastroparesis.Method Sixty patients with diabetic gastroparesis were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by electroacupuncture plus puncturing the thirteen ghost points, while the control group was by electroacupuncture alone. The clinical efficacies were then compared.Result The total effective rate was 93.3% in the treatment group versus 83.3% in the control group, and the difference was statistically significant (P<0.05). Conclusion Electroacupuncture plus puncturing the thirteen ghost points is an effective approach in treating diabetic gastroparesis.

Long noncoding RNA (lncRNA) comprises a group of RNAs that are longer than 200 nucleotides. The lncRNA does not contain functional open reading frames and cannot encode proteins. RNA accounts for a large proportion in the total noncoding RNAs. The number, type, and function of lncRNA are unclear, so they have been called the dark matter of the genome. With the applica-tion of a new generation of gene sequencing technology, lncRNA is found to be involved in the mechanisms mediating the signal trans-duction pathway, regulating the cell cycle, and inducing cell apoptosis. In this article, the authors summarized the up-to-date research progress on lncRNA in digestive system neoplasms in China and overseas to provide new insights into the genetic diagnosis and treat-ment of digestive system neoplasms in clinics.

Purpose To analyze the 64-row spiral CT manifestations and evaluate the diagnostic value in early primary ureteral carcinoma.Materials and Methods Fifteen cases of early primary ureteral carcinoma proved by surgery and pathology were reviewd.Unenhanced scan,enhanced scan in arterial phase,parenchymal phase,delayed phase and CPR construction were performed in all patients.MIP were performed in 10 cases.Results ① the localization of lesions:7cases were located at the right ureter and 8 cases at the left.2 cases were located at the upper portion of the ureter,6 at mid portion,and 7 at lower portion;② CT manifestations:8 cases showed irregular thickened wall and central lumen stenosis,4 cases eccentric soft tissue mass in lumen and crescent or linear vestigial lumen,3 cases soft tissue density and obsolescent lumen;③the enhanced features:the tumor was demonstrated apparent and uniform enhancement in 13 cases,inhomogeneous enhancement in 2 cases after administration of contrast medium;④ the accompanied signs:proximate renal and ureteral presented distention,dropsy in different degrees,5 cases appeared delayed development.Conclusion 64-row spiral CT volume scan and 3D reconstruction with multiplane and multiorientation,combined with axial enhanced scan,can show lesions dimensionly and increase the dignostic accuracy in early primary ureteral carcinoma,which has an important value.

Objective To observe the application of low dose CT scanning in lung puncture biopsy,and to discuss the feasibility and limitations.Methods 100 cases of CT guided percutaneous lung biopsy,used SPSS soft-ware to generate random numbers,odd number into the routine dose group,even number into low doses study group. The routine dose group of 50 patients underwent routine dose CT scanning(200mA,reconstruction thickness 2.0mm, pitch 16mm/rot)and puncture,and the low doses study group were given low dose CT scanning in 50 patients (10mA,reconstruction thickness 2.0mm,pitch 23mm/rot)and puncture.Two groups after routine disinfection punc-ture,were taken tissue samples for pathological examination.The two groups of CT scanning dose and image quality, the success rate of puncture and complications were compared.Results The success rate of puncture in conventional dose scan group was 90.00%;CT dose index weighted index CTDIw was (23.64 ±5.91)mGy;the average dose length product DLP was (172.31 ±43.08)mgy ×cm.The success rate of puncture of the low doses study group was 84.00%;CTDIw was (1.22 ±0.31)mgy;DLP was (8.56 ±2.14)mgy ×cm.The successful puncture rate of the two groups had no significant difference(χ2 =0.638 9,P=0.374 2);The radiation dose was statistically significant(CTDIw compare:t=2.798 3,P=0.005 4;DLP compare:t=2.684 9,P=0.007 8);The image quality can meet the need of puncture biopsy;At the same time,the two groups had no severe complications.Conclusion Low dose than routine dose CT scanning in lung biopsy success rate has no difference,but which can significantly reduce the radiation dose.

Extramedullary infiltration is one of the reasons of relapse and death for leukemia patients.Reaearches increasingly show that extramedullary microenvironment plays a pivotal role on progress and relapse of leukemia.Extramedullary infiltration of leukemia is the result of interactions among many factors and many steps,involving liver,spleen,central nervous system,thymus and other tissues and organs.

Purpose: To investigate the therapeutic effect of acupuncture and herbs in chloasma.Methods: Chloasma was divided into three patterns and treated by acupuncture plus oral administration and external application of Chinese herbs. Results: There was an obvious therapeutic effect in chloasma treated by combination of acupuncture and herbal drugs. After two courses of the treatments, the effective rate accounted for 93.3% in 45 cases. Conclusion: There was an obvious therapeutic effect in chloasma treated by combination of acupuncture and herbal drugs.

Primary mediastinal large B-cell lymphoma represents a distinct entity with unique clinicopathologic features and a molecular gene-expression signature. There is no standard regimens. Retrospective analysis suggests that dose-dense and dose-intensive regimens are more effective than CHOP. The addition of rituximab may mitigate such difference. The role of mediastinal radiotherapy upon completion of chemotherapy remains unclear. The role of PET scanning requires prospective examination, which may allow the de-escalation of treatment if it can be shown to yield reliable prognostic information.
