AIM:To evaluate the effect of all capsule polishing with polishing mode for decreasing the occurrence of posterior capsular opacification( PCO) .
METHODS: Totally 194 eyes ( 162 patients ) were performed phacoemulsification, posterior chamber intraocular lens were implanted. One hundred eyes were performed with all capsule polishing with polishing mode;94 eyes were performed with the polishing apparatus.
RESULTS:The patients were followed up for 12mo. Six eyes ( 6. 0%) of PCO were found in the 100 eyes with polishing mode group; 15 eyes ( 16. 0%) of PCO were found in the 94 eyes with the polishing apparatus group. The difference was significant (P<0. 05).

BACKGROUND:Some studies have demonstrated that there is a clear correlation between osteocyte differentiation and leptin. Animal experiments have also confirmed that leptin indirectly inhibits the formation of osteoblasts through the central nervous system, but it also has some influences on the anabolism in bone microenvironment of osteoblasts. OBJECTIVE:To analyze the variation of serum leptin levels in older female patients with osteopenia, and the relationship between serum leptin levels, bone mineral density and related biochemical indexes of bone turnover. METHODS: The older female patients, aged≥ 60 years, who had lived in Xinjiang Uygur Autonomous Region for more than 30 years, were selected. Among these patients, 74 had osteoporosis, 111 had osteopenia, and 191 had normal bone mass. Serum leptin levels, bone alkaline phosphatase and other indicators of the patients were detected using enzyme-linked immunoassay method. RESULTS AND CONCLUSION:Compared with the normal group, the body mass index value and leptin level were significantly lower in the osteoporosis group (P < 0.01) and in the osteopenia group (P < 0.05). The bone mineral densities of al parts of patients in the osteoporosis group were lower than those in the osteopenia and normal groups (P < 0.01), and the bone mineral density value of patients in the ostopenia group was significantly lower than that in the normal group (P < 0.01). The serum leptin levels of older female patients with osteoporosis were significantly positively correlated with the bone mineral density value of the anteroposterior lumbar spine and the left hip bone (r=0.870,r=0.468,P < 0.01). The serum leptin levels of older female patients with osteopenia were significantly positively correlated with the bone mineral density value of the anteroposterior lumbar spine and the left hip (r=0.477, r=0.467,P < 0.01). The serum leptin levels of older female patients with osteoporosis were significantly positively correlated with body mass index (r=0.502,P < 0.01). These results suggest that reduced levels of serum leptin may play an important role in the pathogenesis of osteoporosis and osteopenia in older female patients in Xinjiang Uygur Autonomous Region, China.

Chinese Journal of Tissue Engineering Research 2015;19(20):3152-3157
BACKGROUND:Studies have shown that there is a certain correlation between blood lipid levels and bone mineral density in postmenopausal women, but their correlation in men is an open question, which has been less reported. OBJECTIVE:To investigate the relationship between blood lipid levels and bone mineral density in Han and Uygur men with hypertension in Urumqi of Xinjiang Uygur Autonomous Region, as wel as correlation of blood lipid levels with osteoporosis and osteopenia and difference between ethnics. METHODS: A total of 193 male patients with hypertension were categorized into Uygur (n=73) and Han (n=120) groups. Each group was subdivided into osteoporosis or osteopenia group and non-osteoporosis group. Bone mineral density and blood lipid level were analyzed and compared between groups. The correlation between osteoporosis and risk factors was analyzed using logistic regression method. RESULTS AND CONCLUSION:In Uygur hypertension men with osteoporosis or osteopenia, total cholesterol level was positively correlated with the bone mineral density of the femoral neck (r=0.43,P=0.01) and Ward's area (r=0.42, P=0.01); while there were no relationships between blood lipid levels and bone mineral density in Han hypertension men. When a Logistic regression analysis was performed, only total cholesterol level was found to be associated with the presence of osteoporosis or osteopenia after adjustment for body mass index, age and ethnics (OR=1.48,P=0.03). The blood lipid level is associated with bone mineral density in Han and Uygur men with hypertension from Urumqi of Xinjiang Uygur Autonomous Region, which can affect the presence of osteoporosis.

OBJECTIVETo study the effects of soil microbes of habitats on the cuttings rooting of Huperzia serrata and its mechanism.
METHODThe cuttings of H. serrata were planted on the primary habitat soil and on the soil autoclaved, rooting rates were examined respectively. Changes of contents of phenolic compounds (catechin, quercetin, chlorogenic acid, ferulic acid) and indoleacetic acid (IAA) , and changes of activities of polyphenoloxidase (PPO) and peroxydase (POD) during the cuttings rooting were determined.
RESULTSoil microbes of primary habitat could increase the rooting rate and the number of roots, could increase contents of catechin, chlorogenic acid, ferulic acid and IAA during rooting, and could affect activities of PPO and POD.
CONCLUSIONDuring the rooting higher contents of catechin, chlorogenic, ferulic acid and IAA caused by soil microbes of primary habitat are important factor for rooting rate.

Aim The purpose of this study was to compare the differential expression of 15-lipoxygenase isoenzymes in the pulmonary arteries between normoxia and hypoxia and to explore their roles in the formation of hypoxic pulmomary vasoconstriction. Method Eighteen SD rats were randomly divided into two groups(n=9):the normoxic control group breathing fresh gas and the hypoxic group breeding in animal hypoxic incubator.Immunohistochemical method,in situ hybridization and Western blot were employed to determine certain 15-lipoxygenase isoenzymes which involved in the process of hypoxic pulmonary vasoconstriction.Results ①In normoxic control group,the expression of 15-LO-1 protein was detected in the pulmonary arteries;but the expression of 15-LO-2 protein wasn’t detected.②The expression of 15-LO-1 protein in hypoxic group was much stronger than that in normoxic group (P
