Objective To investigate the value of Helicobacter pylori (HP),blood carcinoembryonic antigen (CEA),carbohydrate antigens 72-4 (CA72-4) and CA24-2 in the screening of gastric cancer.Methods The contents of HP,blood CEA,CA72-4 and CA24-2 in 50 healthy controls,45 patients with benign gastric lesions mnd 70 patients with gastric cancer were detected.According to the number of positive cases,the positive rate of single detection and the positive rate of combined detection were calculated.Sensitivity,specificity,and accuracy of serum tumor markers were calculated according to HP single and combined detection.Results The positive rate of each individual detection and 4 joint detection in gastric cancer group was significantly different from that in the benign lesion group and the normal control group (P ＜0.01).The positive rate of 4 joint detection in gastric cancer group was 89.25％,and the difference was statistically significant (P ＜0.01).There was no significant difference in the positive rate of the single test and the 4 joint detection in benign stomach group and normal control group (P ＞ 0.05).The sensitivity,specificity and accuracy of HP,blood CEA,CA72-4,CA24-2 joint detection were significantly higher than single detection (P ＜ 0.05).Conclusions Joint detection was significandy better than single detection,and can significantly improve the detection rate of gastric cancer.

Objective To investigate the clinical and pathological features of colonic polyp canceration and related risk factors of colon polyps,and explore clinicopathologic features and major risk factors of the canceration of polyps of colon polyps.Methods Totally 80 patients with colon polyps including 6 cases of cancerations and 20 patients with colon cancers were selected from Xuzhou Tumor Hospital Admissions.Those patients were divided into 74 cases of non cancer group and 26 cases of cancer group.The clinical data,the detection index and the statistical analysis were performed.Results The clinical features of patients included 51 cases of multiple polyps,30 cases of fatty liver,13 cases of fecal occult blood positive,and 30 patients with colonoscopy.There were 218 polyps,191 data intact,and 6 cases showed cancer (3.14％).Inflammatory polyps mainly occurred in rectum,cecum,and significant risk other than the colon.Tubular adenoma occurred mainly in the transverse colon.Sigmoid colon cancer colon polyps of the highest risk showed OR =2.30 (P ＜ 0.05).The cancer risk from high to low was from tubular villous adenoma to villous adenoma hair (P ＜0.01),and no difference in tubular adenoma cancer risk (P ＞0.05).There was no difference between the indexes of the canceration group and the non cancerous group (P ＞ 0.05).The single factor analysis showed pathological type,and the lesion were the main risk factors of malignant colonic polyps (P ＜ 0.05).Multi-factor regression analysis showed WBC,pathological type,and the lesion were the main risk factors of malignant colonic polyps (P ＜ 0.05).Conclusions The colonic polyps in male have higher incidence with fatty liver,hypertension and other pathological features,and are mainly tubular adenomas,inflammatory and hyperplastic polyps,with different lesions,pathological types occur and different cancer risk.

The authors reported their experience in treatment of 17 patients with hepato-gastrointestinal neoplasms with lipiodol embolization chemotherapy via subcutaneous infusion port by a non-surgical method since March, 1994. According to the seldinger method implanted catherter was placed in the suitable target artery, and the Subcutaneous infusion port was linked to the implanted catheter through a subcutaneous tunnel. Antitumor chemotherapeutic drugs, biological response modifiers and lipiodol were injected through the port. These results suggest that the non-surgical implant method is simple, safe and effective for regional chemotherapy.

Stressors can be classified as controllable and uncontrollable events.Self-choice behavior plays an important role in the "problem-solution" process of coping when individual faces controllable stressors.As to the uncontrollable stressors there are 2 different coping modes: transformation and compensation coping.This paper reviews the research achievements in the relationship between stress and self-choice behavior.

AIM: To investigate the changes of alkaloid in Rhizorrm Coptidis and Fructus Evodiae before and after combination. METHODS: The content of berberine hydrochloride,palmatine hydrochloride,jatrorrhizine hydrochloride in Rhizoma Coptidis and Fructus Evodiae before and after combination were determined by TLCS.RESULTS : After combination of Rhizoma Coptidis and Fructus Evodiae,contents of berberine hydrochioride,palmatine hydrochloride,jatrorrhizine hydrochloride significantly reduced,among which the reduction of berberine hydrochloride was more obvious.CONCLUSION: In decoction,Fructus Evodiae appears to restrict the alkaloid from Rhizoma Coptidis in order to lower the side effect of Rhizoma Coptidis.

Objective To evaluate the influence of chronic urticaria on the quality of life in patients by the DLQI, and to assess the factor structure and reliability of the DLQI. Methods The DLQI (Chinese version) was used to evaluate the quality of life of outpatients with CU. The reliability and factor structure of the DLQI were evaluated by reliability analysis and factor analysis. Results Eighty-five patients were asked to complete the DLQI and 13 patients were excluded for other complicated disorders or unanswered items in the DLQI. The mean age was 33.43 ± 0.90 years in the 72 patients with a median clinical course of 6 months. The DLQI score, which varied from 1 to 23 with an average of 9.46 ± 0.61, was uncorrelated to the patients' age,sex, or clinical course of CU (all P ＞ 0.05). The impact of CU was observed mainly on the "synptoms and feeling" (50%), followed by "work and study" (40.67%). Factor analysis indicated that there were two dimensions with eigenvalues greater than 1.0, accounting for 53.7% of the variances. Reliability analysis showed that the Cronbach's α value was 0.836, and reached 0.849 if the item 1 in the DLQI was deleted. An analysis of variance showed that the F value was 31.88 (P ＜ 0.01 ), and Hotelling T2 test yielded an F value of 29.87 (P ＜0.01 ). Conclusions CU has a moderate impact on the quality of life in patients. DLQI can be applied to the evaluation of quality of life in patients with CU with a high reliability, but more attention should be paid to the interference from item 1 to the reliability of the assessment.

ABSTRACT:Objective To prepare polymeric nanomicelles capable of simultaneously loading doxorubicin (DOX) and Bcl‐2 small interfering RNA (Bcl‐2 siRNA ) , and to explore their in vitro cytotoxicity and cellular uptake in MCF‐7 human breast cancer cells .Methods Copolymer poly (ethylene glycol )‐g‐polyethylenimine‐g‐poly(γ‐benzyl‐L‐glutamate) was synthesized by the combination of reductive amination and carbodiimide methods , and its chemical structure was verified by 1 H NMR .Empty and drug‐loaded copolymeric nanomicelles were prepared by dialysis method and characterized by transmission electron microscope and dynamic light scattering .The ability of the nanomicelles to compress Bcl‐2 siRNA was measured by by agarose gel electrophoresis method . The release profiles of DOX and Bcl‐2 siRNA from the nanomicelles were explored by means of fluorescence spectrometry and dialysis method .The in vitro cytotoxicity and cellular uptake of DOX and Bcl‐2 siRNA co‐loaded nanomicelles in MCF‐7 human breast cancer cells were characterized by MTT assay and confocal laser scanning microscopy , respectively .Results The critical micelle concentration of the copolymer was about 4 mg/L ,and the sizes of self‐assembled empty and drug‐loaded nanomicelles were smaller than 200 nm .The drug‐loading efficiency and drug‐loading content of DOX in the nanomicelles were 88 .7% and 15 .1% ,respectively .The DOX‐loaded nanomicelles could efficiently compress Bcl‐2 siRNA when an N/P ratio was ≥64 .The zeta potential of DOX and Bcl‐2 siRNA co‐loaded nanomicelles was +30 mV .The release behavior of the cargoes from the nanomicells was pH‐sensitive , and the release of Bcl‐2 siRNA was more sensitive to acidic pH than that of DOX . The nanomicelles could simultaneously deliver DOX and Bcl‐2 siRNA into MCF‐7 cells , and the co‐delivered DOX and Bcl‐2 siRNA significantly increased the cytotoxicity of DOX (P<0 .05) .Conclusion The polymeric nanomicelles can co‐load DOX and Bcl‐2 siRNA and deliver them into MCF‐7 cells , and DOX in combination with Bcl‐2 siRNA can synergistically inhibit the growth of MCF‐7 cells and promote cell apoptosis ,suggesting that the nanomicells may be a promising carrier for the co‐delivery for chemotherapeutics and genes .
