ObjectiveTo investigate the expression and localization of midkine (MK) in human hepatocellular carcinoma. MethodsIn situ hybridization and immunohistochemical analysis for MK were performed on samples of both tumor tissues and paratumor tissues from HCC and benign liver tumors. ResultsThe distribution and localization of the MK transcripts′ signals determined by in situ hybridization were similar to those obtained by immunohistochemical analysis. Most HCC tissues showed enhanced positive reaction within cytoplasm to both MK probe and MK immunostaining. There was no significant difference in clinicopathological parameters between MK negative and positive cases of HCC. ConclusionsHuman hepatocellular carcinoma overexpresses MK at the mRNA and protein level.

Objective To study the influence of probiotics on the gut microflora,digestive enzymes and small intestinal propulsive rate of rats with severe head injury. Methods The rat model of severe head injury was prepared, SD rats were randomly divided into group A (enteml nutrition) , group B (enteral nutrition plus probiotics) , and group C (normal diet) . The intestine mucesa and faeces were collected on the third day,7th day and 14th day after head injury in order to detect gut microflora,digestive enzymes and small intestinal propulsive rate. Results Compared with group C, the number of Lactobacillus and Bacillus bifidus group in group A and group B declined in two weeks after trauma, however, the number of Escherichia coli increased significantly. Bacillus bifidus amounts of group A were significantly lower than that of group B at every time point, the diversity of Escherichia coli was opposite. No difference was seen in content of Lactobacillus 7 days after trauma in group A and B. The level of disaecharidases, Na+- K+- ATPase and small intestinal propulsive rate declined significantly at every time point, compared with group C.Though the contents of digestive enzymes was higher in group B than that of group A, and small intestinal propulsive rate was higher in group A and B than that in group C, but the two groups showed no difference. Conclusions Probiotics can alleviate the in-testine microflora disorder,modulate the activities of digestive enzymes, therefore lessen malabsorption of rats with severe head injury.

OBJECTIVE To investigate and evaluate the effects of intact-bridge tympanoplasty using auricular cartilage in treating chronic otitis media. METHODS A retrospective review of 86 cases undergoing an intact-bridge tympanomastoidectomywas performed from July,2013 to May,2016.The auricular cartilage was placed on the attic and tympanic antrum entrance to reconstruct the attic. RESULTS The outcome of dry ear and well-epithelialized mastoid cavities was achieved after 4-6 weeks. After 6-month follow-up no recurrence occurred. The pure-tone average threshold improved by (25.4±6.3) dB HL after operation,and the mean air bone gap was elevated. CONCLUSION On the basis of combination of closed and open techniques,the IBM technique is a optimal cure strategy for chronic otitis media,which can not only remove the pathological changes thoroughly to prevent disease recurrence but also maximally improve the hearing of the diseased ear.The closure of attic with auricular cartilage can ensure the space of the ossicular chain.

Objective To find a simple, effective and inexpensive method for acid copper-containing waste water treatment. Methods Studied the processing of the leaching waste water from the laboratory of East China Institute of Technology and simulated acid copper mine waste water(concentration of Cu2+ is 143.00 mg/L, pH: 1.80-2.00) using the processed eggshells to treat acid copper-containing waste water under the condition of different calcining temperature, eggshells amount,eggshells size and stirring speed. Results The best condition was that the calcining temperature was 400 ℃, the amount of eggshells was 25 g/L, the size of eggshells was 0.25 mm, the stirring speed was 240 r/min. The eggshells could increase the pH values from 1.80-2.00 to 6.86-7.34 and reduce Cu2+ concentration from 0.43 mg/L to 0.09 mg/L, the concentration of Cu2+ in the treated waste water could answer for the first level of the Integrated Waste Water Discharge Standard(GB 8978-1996), the removal rates could reach 99.70%-99.94%. Conclusion Using eggshells to treat acid copper-containing waste water has application prospects for the process, is simple and easy to be operated, the treatment effect is good.

Aim To observe the effect of 5-FU and L-Arg on the human liver carcinoma model in nude mice and study the mechanism.Methods We established the human liver carcinoma model in nude mice with BEL-7402 cell and gave normal saline,5-FU,5-FU+L-Arg by intraperitoneal injection. The tumor size was measured.The necrotic degree and range were observed by the microscope. Immunohistochemistry method and chemical colorimetry were performed to determine the expression and activity of iNOS. Nitrate reductase method was adopted to test the concentration of NO in the tumor tissue. The one-way ANOVA,Bonferroni and Kruskal-Wallis H tests were adopted for the statistical analysis.Results 5-FU combined with L-Arg promoted the tumor suppressive action apparently. The necrotic range enlarged. The expression and activity of iNOS increased. The production of NO also increased.Conclusions 5-FU combined with L-Arg has agonist effects on the inhibition of the growth of human liver carcinoma in nude mice.It may be related with inducing the synthesis of iNOS and the increase of NO.

Objective:To isolate monocytes from human peripheral blood mononuclear cells( PBMC) ,induce macrophages,and identify the function of macrophages.Methods:Monocytes were isolated from PBMC using magnetic activated cell sorting( MACS) anti-CD14 microbead.Sorted CD14+and CD14-cells were checked by flow cytometer to evaluate the efficiency of sorting.The sorted CD14+cells were cultured in IMDM media with 10%human AB serum and 10 ng/ml M-CSF for 7 days to generate macrophages,which were identified by morphological features and phagocytosis function.Results:A high purity of monocytes was obtained by MACS anti-CD14 microbead.The percentage of CD14+cells was 10% and 85.8% before and after sorting, respectively.The macrophages were approximately 40-45 μm in maximum diameter and had the fried egg colony morphological features after 7 days culture.The lymphoma ( Raji) cells were efficiently engulfed by macrophages.Conclusion: The high purity of CD14+monocytes is isolated from PBMC and monocyte-derived macrophages efficiently engulfed lymphoma cells.
