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.

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.

Objective:To observe the clinical effect of Shutiao Decoction on patients with coronary heart disease and anxiety and depression. Methods:Sixty patients with stable coronary artery disease and anxiety and depression from January 2019 to December 2019 in Kunming Municipal Hospital of Traditional Chinese Medicine were selected. They were divided into a treatment group of 30 cases and a control group of 30 cases according to random number table method. The control group recieved Western medicine routine treatment combined with psychological intervention, the treatment group was treated with Shutiao Decoction on the basis of the control group, and the treatment course of both groups was 4 weeks. Before and after treatment, TCM syndrome score, Seattle Angina Scale (SAQ), Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) were evaluated. The adverse events were recorded during treatment and clinical efficacy was evaluated. Results:After treatment, the total effective rate in the treatment group was 90.0% (27/30), the control group was 73.3% (22/30), where the difference between the two groups was statistically significant ( Z=-2.515, P=0.012). After treatment, the TCM syndrome score (9.37 ± 6.47 vs. 18.37 ± 6.58; t=-5.341, P<0.01) of the treatment group was significantly lower than that of the control group. Among SAQ domains’ scores, the physical activity limitation, and the stable state of angina pectoris, angina attack in the treatment group were significantly higher than those of the control group ( t values were 2.294, 7.698, 4.677, 3.215, respectively, P<0.05 or P<0.01). The HAMA score of the treatment group was significantly lower than that of the control group (9.20 ± 5.26 vs. 12.17 ± 4.88; t=-2.266, P=0.027). The HAMD score in the treatment group was significantly lower than that of the control group (11.27 ± 5.83 vs. 15.03 ± 6.16; t=-2.433, P=0.018). During the treatment period, the incidence of adverse reactions was 3.33% (1/30) in the treatment group and 6.67% (2/30) in the control group. There was no statistically significant difference between the two groups ( χ2=0.351, P=0.554). Conclusion:Shutiao Decoction combined with western medicine routine treatment can improve patients’ TCM syndromes, relief angina pectoris, anxiety and depression.

As an advanced quantitative technology for cells, flow cytometry, which can make multi-paramter quantitative analysis and sorting of individual cells or biological particles, has been widely used in immunology, oncology, hematology and other fields of medical research and clinical diagnosis in recent years.It can quantitatively detect the expression levels of cytokines and the distribution characteristics of cell subsets in the intraocular fluid.Compared with traditional enzyme-linked immunosorbent assay, cell morphology and immunohistochemistry, it has the advantages of simple operation, smaller sample size, higher sensitivity and higher throughput.Flow cytometry has been widely used in the detection and subgroup analysis of cytokines related to eye diseases, such as intraocular angiogenesis, intraocular lymphoma, retinopathy, cataract, uveitis, sarcoidotic uveitis, infectious intraocular inflammation, etc.Flow cytometry plays an increasingly important role in the pathogenesis research and targeted therapy of eye diseases.In this article, the application of flow cytometry in the examination of cytokines and cytology in ocular fluid for ocular diseases were reviewed.
