5.Acupuncture and tuina clinical thoughts of "treating the back from abdomen" for low back pain.
Chinese Acupuncture & Moxibustion 2015;35(7):715-717
In clinical treatment, it is found that certain patients always have some positive reaction points those are relevant with low back pain in the abdomen area. When the simple treatment on the low back is ineffective, the efficacy could be significantly improved if acupuncture or tuina is performed at the abdomen areas, which is called "regulating yin to treat yang", or "treating the back from abdomen". In this paper, with the diagnosis and treatment method of "treating the back from abdomen" for low back pain as principal line, the detailed manipulation is explained for low back pain that is induced by TCM meridian diseases or modern anatomy, which could open the methods for clinical treatment of low back pain and enrich the therapeutic options.

7.Effect of Resveratrol on the Expression of Survivin and p27 Protein in Human Renal Cell Carcinoma 786-0 Cells
Herald of Medicine 2015;34(12):1572-1575
Objective To investigate the effect of resveratrol ( Res ) on the expression of survivin, p27 protein in human renal cell carcinoma 786-0 cells. Methods The cell cycle and apoptosis of 786-0 cells were detected by flow cytometry, and the expression of survivin and p27 protein of 786-0 cells was detected by Western blotting at time point of 12, 24 and 48 h after human renal cell carcinoma 786-0 cells were cultured with Res ( 25μmol·L-1 ) and blank medium, respectively. Results The ratio in G1 phase [(64.87±3.76)%] and G2 phase [(9.91±0.82)%] in the experimental group decreased significantly (P<0.05), and the ratio of S phase [(25.05±3.12)%] increased significantly (P<0.05).The apoptosis rate of experimental group at 12, 24 and 48 h [(5.12±0.64)%, (5.71±0.49)%, (5.84±0.30)%] was significantly higher than that of the control group [ ( 0. 72 ± 0. 27 )%, ( 0. 93 ± 0. 25 )%, ( 1. 12 ± 0. 21 )%, P<0. 05 ] . The expression of survivin protein in experimental group was significantly higher than that of the control group ( P<0. 05 ) , and the expression was significantly increased with time prolonging (P<0.05).The expression of p27 protein in experimental group was significantly lower than that of the control group (P<0.05), and the expression level was significantly decreased in time-dependent manner (P<0.05).There was a negative correlation between the expression of survivin and p27 protein in the experimental group ( P<0.05) . Conclusion Res could inhibit the expression of p27 protein and up-regulate survivin expression level, and promote the apoptosis of renal cell carcinoma 786-0 cells.
8.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.
9.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.
