ObjectiveTo evaluate the instant response and side effects of hypofractionated high-dose 3-dimensional conformal radiotherapy (3-DCRT) for esophageal carcinoma treatment.MethodsSixty-nine patients with esophageal carcinoma were treated by 3-DCRT and 91 patients with routine radiotherapy.The prescribed dose was from 3000 to 4500 cGy in 3-DCRT group, with fractionated dose 300 cGy, one dose a day and five doses a week.The reference dose curve was the 90％ of the isodose curve.For the routine radiotherapy group,the prescribed dose was from 4000 to 6600 cGy,fractionated by 180 ～200 cGy a time,once a day and 5 times a week.Results At the end of the radiotherapy, 3-DCRT produced CR 42.0％ (29/69) , PR 49.3％ (34/69) and instant response rate 91.3％, while routine radiotherapy produced CR 35.2％ (32/91), PR 59.3％ (54/91) and instant response rate 94.5％, respectively.The difference was not significant between the two groups(P ＞ 0.05) .The survival rates one year after the treatment were 82.6.0％ (57/69)and 84.6％ (77/91) ,respectively.The acute radiation esophagitis rate was 66.7％ (46/69) in 3-DCRT group and was 64.8％ (59/91) in routine radiotherapy grouprespectively.ConclusionHypofractionated high-dose 3-DCRT is feasible for treatment of esophageal carcinoma.

Objective To investigate the clinical presentation, morphological features, immunohistochemical staining of the gastrointestinal stromal tumor (GIST), and its histogenesis as well. Methods The morphologic characteristics of GISTs were studied in 58 cases using light microscopy. The expression of c-kit(CD117), CD34 and vimentin were detected in all of the cases with EnVision staining. Results Among 58 cases of GISTs, 41 were spindle cell type, 5 epithelioid cell type and 12 mixture type, equivalent to 86.6 %(58 of 67) of all of the mesenchymal tumors of gastrointestinal tract admitted in the same period. The epithelioid cell type tumors were mainly composed of the epitheloid cells, predominantly short spindle, oval or round in pattern, with an overall eosinophilic cytoplasm by hematoxylin-eosin stain. Focal cytoplasmic vacuolization was often seen. Sometimes signet-ring like cells and cells with a clear cytoplasm were seen in the epithelioid stromal tumor. The tumor cells arranged in interlacing fascicles forming whorls or sometimes cell clusters. All of the 58 stromal tumors were strongly positive for vimentin (100 %), 55 out of 58 tumors positive for CD117 (94.8 %) and 46 out of 58 positive for CD34(79.3 %). Some cases also expressed SMA, actin, S-100 and MBP. Conclusions GISTs were the most common mesenchymal tumor seen in the gastrointestinal tract. Under light microscope, the morphology of stromal tumors sometimes looks like a leiomyoma or Schwannoma. The application of immunohistochemical markers (particularly CD117 and CD34) is considered necessary for the differential diagnosis. GISTs may originate from the pluripotential precursor cells like the interstitial cells of Cajal.

Objective To study the value of expression of carcinoma-associated antigens in early diagnosis and prediction of prognosis of gallbladder carcinoma. Methods The expression of PCNA, CEA, CA50 and E-cad were detected by immunohistochemistry in 50 cases of gallbladder carcinoma, 10 gallbladder adenomas and 10 cholecystitis. Results The positive rates of CEA, CA50 and PCNA LI in gallbladder carcinomas were significantly higher than that of gallbladder adenomas and cholecystitis(P

In this paper,the method about hydrolysis of fish oil with lipases for concentrating DHA(docosahexenoic acid) in glycerides was studied.Six lipases were screened with comparing the activities of hydrolysis of fish oil.Candida lipalytica Lipase is resistant to generating DHA in fish oil.The Effects of the quantity of lipases,the emulgent,hydrolysis time,temperature in the process,the ratio of oil to water were studied.The optimum conditions for the hydrolysis of fish oil are 12 hours of hydrolysis under 45℃,with 300 u?g -1 .The emulgent was and the ratio of oil to water was 0.4 mL?g -1 .Under these conditions,the content of DHA in glyceride were concentrated from 18.7% to 34.0%.But the EPA content remained close to that of fish oil.The DHA glyceride containing triglyceride,diglyceride and monoglyceride was identified by IR spectrum combining with separation of HPLC.

Objective To explore the differences of the proliferation ability and the antineoplastic activity of CIK cells against origenal hepatocellullar cancer cells between healthy adults and tumor patients in vitro. Methods Peripheral blood mononuclear cells (PBMC) from healthy donors and tumor patients were incubated to induce CIK cells in the presence of interferon gamroa(IFN-γ) ,IL-2 and anti-CD3 monoclonal antibody (mAb). The changes in the proliferation activity and phenotypes of the CIK cells were identified by flow cytometric analysis. Single cell suspension was prepared bom the fresh hepatocellular carcinoma tissue by using mechanical trituration method. MTT assays were used to determine the cytotoxicity of CIK cells against origenal hepatocellullar cancer cells. Results The CIK cells from both healthy donors and tumor patients were significantly increased with the extension of time. The expression rate of CD3+/CD56+ cells from healthy donors rose from 1.053% ±0.22% on 1st day ,25.36% ±2.19% on the 7th day to 55.12% ±1.99% on the 14th day ,which was significantly higher than that of tumor patients ( P ＜ 0.05). MTT assays showed that the cytotoxicity of CIK cells from both enhanced obviously with the addition of Effect/Target rate and extension of time(P ＜0.05). After the origenal hepatocellullar cancer cells were treated by CIK cells 24 hours, the cytotoxicity of CIK cells from healthy donors at the effector:target ratio of 10 ∶ 1,20 ∶1 and 40 ∶1 was significantly higher than that of tumor patients(P＜0.05) ,respectively. After treated 48 hours, compared with tumor patients, the cytotoxicity of healthy donors? CIK at the three effector:target ratio was alsosignificantly higher(P ＜0.05), respectively. Conclusion CIK cells from both have amplification ability and cytotoxic activity in vitro,and the proliferation ability and killing activity of healthy adults CIK is stronger than that of tumor patients,which provides an experimental basis for CIK to clinical application as an adoptive immunotherapy.

Objective To evaluate the clinical effect of one-stage posterior-anterior approach surgery for patients with cervical fracture and dislocation combined with locked facet.Methods A retrospective review was conducted on 21 cases of cervical dislocation and fracture combined with locked facet treated by one-stage posterior-anterior approach surgery between April 2011 and December 2012.There were 16 males and 5 females at age ranging from 23 to 61 years (mean,38.3 years).Posterior unlocking reduction by partial facetectomy and lateral mass screw fixation was performed,followed by anterior decompression,internal fixation and interbody fusion by titanium meshes.Outpatient or telephone follow-up was performed to evaluate bone fusion and recovery of neurologic function.Results Mean operation time was 140 minutes (130-210 minutes) and mean blood loss was 340 ml (range,150-600 ml).All incisions got primary healing with no operation-correlated complications.Five patients complicated with severe lung infection after surgery and one died of respiratory failure two week later.Titanium meshes achieved bone fusion within 3-9 months (mean,6 months) after surgery.At a mean follow-up of 17 months (range,12-30 months),there was no implant breakage and mesh displacement or collapse.According to the American Spinal Injury Association (ASIA) score,preoperative neurologic deficit restored by mean one grade at final follow-up.Conclusion One-stage posterior-anterior approach surgery is an ideal choice for cervical fracture and dislocation combined with locked facet,for it provides unlocking reduction,canal decompression,and rigid reconstruction of the anterior-posterior column.
