Objective To study the expression of CD147 and collagen Ⅳ protein in gastric carcinoma.Methods Immunohistochemical assay was used to detect the expression of CD147 and collagen Ⅳ protein in 119 cases of gastric carcinoma, 20 cases of normal gastric tissues, and the clinical data was analyzed.Results In 119 cases of gastric carcinoma, the positive expression of CD147 protein was 83.2 %(99/119), the positive expression of collagen Ⅳ protein was 31.9 %(38/119). The expression of CD147 and collagen Ⅳprotein had relationship with metastasis of lymph nodes,depth of invasion and clinical phases (P <0.05). There was negative significant correlation between the expression of CD147 and collagen Ⅳ protein in gastric carcinoma (P<0.01). Conclusion The expressions of CD147 and collagen Ⅳ protein may be used as one of the marks to study gastric carcinoma.

Objective To investigate the proliferative inhibition of lens epithelial cell (LEC) by arsenic trioxide (ATO) and rhizoma curcumae (RC), in order to provide scientific basis for pursuing safe and effective natural drugs to prevent and cure after cataract. Design Experimental study. Participants Cultured Bovine LEC in vitro. Methods Changes of cellular form were observed with microscope. Different concentration of ATO (2.5, 5, 10?mol/L) and RC(5, 10, 20mg/ml) were added to the proliferative LEC separately. The effects of proliferative inhibition by ATO and RC on the LEC were measured with methyl thia-zolyl tetrazolium (MTT) assay method after 72 hours incubation. Main Outcome Measures Cellular form, Absorbance. Results Under the microscope, good growth and quantity increase were found in proliferative control group. Slowing proliferation,poor growth, and few disintegration were observed in ATO group and RC group. MTT assay: Different concentration of ATO (2.5, 5, 10?mol/L)and RC(5, 10, 20mg/ml) can significantly inhibit the proliferation of LEC and these effects were dose dependent(P

Objective To explore the morphology,cell phenotype and cell function in dendritic cells (DCs) derived from bone marrow after treatment with Sirolimus or Sirolimus combined with sTNFRI-IgGFc gene segment transfection.Method DCs were divided into 5 groups (imDCs,mDCs,Rapa-DCs,sTNFRI-DCs and Rapa-sTNFRI-DCs) according to different interventions.The expresson of MHC-Ⅱ,CD80 and CD86 was detected by flow cytometry.T cell proliferation of the mixed lymphocyte reaction was evaluated by MTT method.The levels of IL-12,IFN-γ and sTNFRI-IgGFc were determined by ELISA.Result On the day 10,the flow cytometry showed that the expression levels of MHC-Ⅱ,CD80 and CD86 on the cell surface in Sirolimus group were significantly higher than the other groups (P<0.05).The expression level of CD86 in Rapa-sTNFRI group was significantly lower than in imDC group (P<0.05).MTT results demonstrated that T cell proliferation ability in Sirolimus group,sTNFRI group and Rapa-sTNFRI group were reduced as compared with mDC group (P<0.05).The ELISA results revealed that the levels of IL-12 and INF-γ in rnDC group were significantly higher than other groups (P<0.05).The levels of IL-12 and INF-γ in Rapa-sTNFRI group were significantly lower than other groups (P<0.05).Conclusion Sirolimus combined with modified sTNFRI-IgGFc gene could synergistically inhibit maturation of DCs more effectively than Sirolimus or modified sTNFRI-IgGFc gene used alone.

OBJECTIVE: To investigate the signal transduction mechanism of curcumin in inhibiting the proliferation of bovine lens epithelial cell (LEC) induced by recombinant human epidermal growth factor (rhEGF). METHODS: There were three groups in this experiment, which were normal control group, untreated group and curcumin-treated group. Proliferation of LEC was induced by rhEGF (50 microg/L). The concentration of intracellular Ca(2+) ([Ca(2+)](i)) in LEC was measured with Fura-2/AM by spectrofluorimetry. The contents of intracellular cAMP and cGMP were assayed by radioimmunoassay. RESULTS: The [Ca(2+)]i in LEC was obviously increased in the untrated group as compared with that in the normal control group (P<0.01), and the [Ca(2+)](i) in LEC in the curcumin-treated group was highest among three groups (P<0.01). The content of intracellular cAMP in LEC was decreased while the content of intracellular cGMP was obviously increased in the untreated group as compared with those in the normal control group (P<0.01). The content of intracellular cAMP in LEC was higher in the curcumin-treated group than that in the untreated group, while the content of intracellular cGMP was lower than that in the untreated group (P<0.01). CONCLUSION: The antiproliferation effects of curcumin on LEC may relate to the regulations of multiple processes of signal transduction.

(t=24.844,13.092,4.833,15.185,P<0.05).(4) Follow-up situations:80 patients were followed up for 3 months.Two patients in the PTGD + early LC group had postoperative complications,including 1 of bile duct injury and 1 of incisional infection;9 patients of PTGD + delayed LC group had postoperative complications,including 3 of bile duct injury,3 of multiple organ failure,2 of incisional infection,1 of death.There was a significant difference in the postoperative complication between the two groups (x2 =5.165,P<0.05).Conclusion Early LC after PTGD can effectively shorten operation time,reduce volume of intraoperative blood loss,shorten duration of postoperative hospital stay,protect liver function,reduce the expression of serum inflammatory factors at 24 hours after surgery,and reduce postoperative complications.

Objective:To explore the clinical application value of sentinel lymph node biopsy (SLNB) in patients with early breast cancer after local excision surgery.Methods:A total of 93 breast cancer patients with clinical stage T is/T 1-2N 0M 0 who underwent SLNB and were confirmed by using tumor mass excision biopsy from March 2012 to November 2018 in Shanxi Bethune Hospital were retrospectively analyzed. According to the postoperative paraffin pathology, the patients who were successfully detected sentinel lymph node (SLN) were divided into SLN-positive group with metastasis or SLN-negative group without metastasis. The clinicopathological data were used to analyze influencing factors of SLN metastasis and SLN detection number after excision biopsy of breast masses in the two groups. Results:A total of 87 out of 93 patients were successfully detected SLN and the detection rate was 93.5% (87/93). A total of 255 SLN were detected, and the average number was 2.93 in per patient. All were subjected to rapid intraoperative freezing pathological, and 11 cases with positive SLN were detected. There were 17 patients who underwent axillary lymph node dissection (ALND), including 11 cases with positive SLN and 6 cases with SLN undetected. The paraffin pathology showed that 14 patients were confirmed as positive SLN, including 13 macrometastasis and 1 micrometastasis. The SLN false negative rate was 2.1% (3/14) of intraoperative frozen diagnosis. Univariate analysis showed that histological grade and intravascular thrombus of carcinoma were associated with SLN metastasis after breast cancer local excision; the number of SLN detection was effected by body mass index and staining method; the methylene staining method combined with radionuclide method could improve the detection rate of SLN (all P < 0.05). Multivariate analysis showed that the SLN non-detection of obesity patients was 2.651 times as much as that of normal patients (95% CI 1.592-8.194, P=0.010). Conclusion:The SLNB and appropriate tracer method will have a high SLN detection rate and better clinical application value for early breast cancer patients after breast mass resection.

Children with prolonged mechanical ventilation often have complex conditions, such as long hospital stay of PICU.They have many complications and high mortality.In addition, these patients have low quality of life, lack of psychological care, family emotional communication, and heavy burden of disease.The long-term management and rehabilitation of these children should be strengthened.This study summarized the researches of prolonged mechanical ventilation in adults at home and abroad, in order to provide experience for prolonged mechanical ventilation management in children.
