4.Timed morphological changes of human hepatocytes L-02 cultured at high density by the support of spherical porous chitosan microcarriers
Chinese Journal of Tissue Engineering Research 2015;(12):1924-1930
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.

7.Curcumin prevents against osteoarthritis
Chinese Journal of Tissue Engineering Research 2015;(2):277-282
BACKGROUND:Curcumin is proved to possess anti-inflammatory, antioxidant and anti-apoptotic roles. OBJECTIVE: To summarize and discuss the mechanisms and effects of curcumin used for the treatment of osteoarthritis METHODS: PubMed, Embase, Elseveir databases were retrieved for relevant articles published from 1973 to 2014, with the key words of “osteoarthritis, curcumin, chondrocyte, articular cartilage” in English. After the quality of the included studies was evaluated, valid data were extracted and analyzed. RESULTS AND CONCLUSION:Curcumin prevents the occurrence and development osteoarthritis by inhibiting oxidative enzyme and scavenging free radicals. Curcumin increases production of colagen type 2 through suppressing the reduction of cartilage matrix by matrix metaloproteinases. Anti-inflammatory reaction of curcumin can be achieved by inhibiting cytosolic phospholipase A2, cyclooxygenase-2, and 5-lipoxygenase. Curcumin inhibits interleukin-1β-induced apoptosis of chondrocytes and mitochondrial sweling. Results from clinical trials suggest that curcumin or its derivatives can reduce joint pain and improve the function of knee joints in patients with osteoarthritis. High-concentration curcuminin vitro have been demonstrated toxic effects.
8.Study of mandibular movement trace in skeletal anterior reverse bite malocclusion after the early stage orthodontic treatment of mixed dentition
Medical Journal of Chinese People's Liberation Army 1981;0(06):-
Objective To study the differences between the mandibular movement in empty opening and protrusion trace of the skeletal anterior reverse malocclusion before and after the early protraction treatment in early stage of mixed dentition. Methods ACRUSdigma system, a kind of ultrasonic mandibular movement record system, was used in the study. The kinematic center which can represent the translation and rotation of the condylar and the incisal points were used as reference point to compare the difference of the empty opening and protrusion mandibular movement trajectory of 30 individuals with skeletal anterior reverse bite malocclusions before and after the early protraction facemask treatment. Results For the kinematic center, the typical trajectory was changed, the upper movement disappeared and the distances between vertical and horizontal movements were increased at the end of the treatment in the empty opening movement on the sagittal plane. In the empty protrusion movement, the interplanar distance of the kinematic center was increased significantly on the sagittal plane. For the incisial point, it moved ahead at first and then downward vertically in the empty protrusion movement, and the interplanar distance was increased significantly on the sagittal plane in the empty opening movement. Conclusions By giving the protraction treatment, the relation of upper mandible and submaxilla of the skeletal anterior reverse bite malocclusions is changed. During the later stage of the treatment, for the occlusal splint was ground off, the normal occlusial inducement is built, which affords the rebuilding of temporomandibular joint (TMJ), ligaments and muscles. The trajectory also becomes normal. The normal trajectory may supply a better environment for the development and rebuilding of jaw, TMJ, ligaments and muscles.
