Abstract BACKGROUND: Recently, microcarrier culture as a high concentration cel culture technology has been used in hepatocyte culturein vitro. OBJECTIVE:To periodicaly observe the morphological changes of human hepatocyte L-02 cultured by the spherical porous chitosan microcarrier. METHODS:The self-made spherical porous chitosan microcarrier sample as a support to culture human hepatocytes L-02 acted as experimental group; non-spherical porous chitosan microcarrier as a support to culture human hepatocytes L-02 as control group. Cels in two groups underwent cel count at regular time, and the morphological changes were observed in the experimental group, including inverted phase contrast biological microscope observation and scanning electron microscope observation. RESULTS AND CONCLUSION:The quantity of cultured cels in the two groups was increased in the first 3 days and reached the peak at the 3rd day. The cel quantity in the experiment group was obviously higher than that in the control group (P < 0.05). There was no significant difference in the three samples of the experimental group (P > 0.05). The quantity of hepatocytes adhered to the microcarrier surface was gradualy increased in the former 3 days under the inverted phase contrast biological microscope. There were lots of cel clusters on the surface of a greater part of microcarriers, with the total survival rate of more than 90%, and hepatocytes kept a good morphological structure. Under the scanning electron microscope, lots of hepatocytes adhered tightly to each other on the surface and section of microcarrier as wel as inside the microcarrier. It is indicated that the self-made spherical porous chitosan microcarrier as a support in three-dimensional environment can undergo cel culture with high concentration.

Exosome is a sort of vesicle structure attached to cell membrane and released by cells, which contains numerous bioactive molecules, such as proteins, lipids, mRNA, microRNA and DNA fragments. These bioactive molecules are involved in the regulation of many biological processes, not only the participation in the occurrence and development of diverse diseases, but also the close relationship with the invasion and metastasis of tumors. The recent study has indicated that lots of exosomes released from cancer cells participate in a variety of pathological processes as a messenger of cell functions. This article will elaborate the function and application of exosomes in some malignant cancers.

Subcutaneous insulin resistance is a condition in which glucose is insensitive to insulin from the subcutaneous tissue,but sensitive to that by intravenous injection.The mechanism of subcutaneous insulin resistance is mainly associated with skin obstruction or delayed entry of insulin into blood circulation.The treatment of the problem involves Aprotinin,anticoagulant and intramuscular injection of insulin.This paper offers an overview of the advances in the researches of subcutaneous insulin resistance.

Objective To observe clinical effect of treating chronic obstructive pulmonary disease(COPD) in exacerbation stage with aerosol inhalation of budesonide combined with Chinese herbal enema. Methods 36 cases with COPD were randomly recurited into a control group and a treatment group. The control group was treated with routine western medicine, and the treatment group was treated with aerosol inhalation of budesonide combined with Chinese herbal enema. The clinical effect was observed in both groups, Results The total effective rate in the treatment group and the control group was 88.9% and 72.2%, respectively, showing significant difference between the two group. (P<0.05) .Conclusion The treatment of aerosol inhalation of budesonide combined with Chinese herbal enema on COPD is better than routine western medicine.

Objective Evaluation of imatinib mesylate treatment of unresectable/marginally resectable gastric and duodenal stromal tumors,as well as its side effect and the toxicity.Methods Oral imatinib mesylate was prescribed at the dose of 400 mg/d for 12 cases of patients with unresectable/marginally resectable gastric and duodenal stromal tumors.The evaluation of the adverse reactions was in accordance with United States NCI-CTC grading standards (3rd edition).Choi standard was used to evaluate the patients at 3 and 6 month time points.Results For hematological toxicity,only 1 case of patient with Ⅲ° decreased white blood cell count,and the rest patients were with Ⅰ° to Ⅱ ° degree.For nou-hematological toxicity,the author observed cardiac toxicity,liver function damage,renal function damage,diarrhea,abdominal pain,nausea/vomiting,fatigue,anorexia,muscle pain,rash,hair loss,skin and mucosa edema.Among them,there was only 1 patient with Ⅲ° skin rash,and 1 patient with Ⅲ° edema,all the rest were with Ⅰ° to Ⅱ °.Eight and 11 cases of patients were evaluated as partial remission (PR) after 3 and 9 months of treatment respectively.Among them,nine patients were given R0 resection and 2 patients denied surgery due to old ages.One patient was stable (SD).Conclusions Preoperative treatment of patients with unresectable/marginally resectable gastrointestinal stromal tumors by imatinib mesylate will increase the resection rate.The related toxicity can be well-tolerated.

Objective To explore the occurrence and prevention and the principle of management of chylous fistula after neck dissection. Methods Retrospective research on 1750 cases of neck dissection in Henan Tumor Hospital from January 1983 to January 2005. There were 48 cases chylous fistula and 1 case chylothorax. The incidence was 2.8 %. 5 cases on the right, 44 cases on the left. 18 cases had completed radiotherapy or chemotherapy before operation. Conservative methods and surgical methods were used in the treatment. Low fat food was supplied to the patients with chylous fistula. The conservative methods was local pressure, the surgical methods was applied while maximal production of chylous exceeding 500 ml a day. Results All the patients were cured finally. The conservative method was 12.6(5~34) days, the surgical method 7.5(3~10)day. Conclusion The key to prevent chylous fistula was to band the rupture of thoracis or lymphatic duct during operation. The conservative methods could be used in patients with slight and middle chylous, when the chylous exceed 500 ml a day or the conservative methods was unavailable, the surgical methods was appropriate, it could shorten the time of tube draw.
