BACKGROUND:Studies have shown that Ganoderma lucidum polysaccharides have biological activities of anti-viral, anti-tumor, enhance immunity, anti-oxidative and anti-aging. OBJECTIVE:To observe the biological effect of Ganoderma lucidum polysaccharides on the antioxidant capacity of D-galactose induced aging mice skin tissues, and to observe the effect in postponing skin aging. METHODS:Forty-four 2-month-old Kunming mice were randomly divided into four groups:normal control group, aging model group, vitamin E group, and Ganoderma lucidum polysaccharide group. Rats in the last three groups received subcutaneous injection (nape area) of Ganoderma lucidum polysaccharide to establish rat aging models, and intragastric administration of corresponding drugs or saline was performed. After 42 days, pathological sections of back skin were obtained to assess the morphological changes of skin tissues, measure the epidermal and dermal thickness, and detect the superoxide dismutase levels and the expression of CuZn-superoxide dismutase mRNA. RESULTS AND CONCLUSION:The epidermal and dermal thickness in the vitamin E group and Ganoderma lucidum polysaccharide group were increased when compared with the aging model group. The superoxide dismutase levels in the Ganoderma lucidum polysaccharide group were significantly higher than those in the other two groups. The decreased degree of cycle threshold value in the Ganoderma lucidum polysaccharide group was lower than that in the other two groups. The results indicate that Ganoderma lucidum polysaccharide can increase the epidermal and dermal thickness, improve the skin tissue structure, and enhance the superoxide dismutase levels and the expression of CuZn-superoxide dismutase mRNA.

AIM:To investigate the process and advantages of wound repair at one stage after repair of nasal skin defect with bilobed flap.METHODS:Under local infiltration anesthesia,nasal skin defects were repaired by bilobed skin flaps.The normal skin around the defect was designed for bilobed island skin flaps.The maximum size of the flaps was 1.8 cm?2.5 cm,and the minimum size was 0.8 cm?1.0 cm.And then the flaps were transferred to repair the defects.The distances from incisions to margin of lesions were as follow:hemangioma was 0.2 cm,basal cell carcinoma was 0.5-0.7 cm,and melanoma was 1.0 cm.The depths of incisions reached superficial fascia layer.Complete hemostasis of wound was performed.RESULTS:Fifty of 92 patients were followed up for 6 months,and 42 of them were followed up for 12 months.In all patients,the nasal skin defects were repaired completely with primary healing.The color and texture of the flap were the samilar with the adjacent skin,and the nose contour and cosmetic results were satisfactory.CONCLUSION:Repair of bilobed island skin flap for nasal skin defeets was simple,and the efficacy was satisfactory.

Objective To investigate the method and curative effect for the operative treatment of acetabular fractures.Methods Forty-one patients with acetabular fractures were treated operatively from March 2001 to March 2006.All fractures were classified according to the Letournel-Judet classification,22cases were simple fractures and 19 cases were complicated fractures.Kocher-Langenbeck (K-L) approach were adopted in 31 cases (14 cases through osteotomy of greater trochanter additionally),ilioinguinal approach were adopted in 8 cases and anterior combined posterior approach were adopted in 2 cases.Different fractures were fixed by reconstructive plates and screws.Results All the patients were followed up for 16-36 (24.31 ± 5.31 ) months.According to the reduction criteria of Matta radiography,there were 27 cases with anatomic reduction,8 cases with satisfactory reduction,3 cases with poor reduction and 3 cases with joint contour reduction.According to the Merle D' Aubigne clinical criteria for joint functions,14 cases showed excellent results,18 cases were good,5 cases were fair and 4 cases were poor,and the excellent-good rate was 78%( 32/41 ).Necrosis of the femoral head was found in 3 cases,heterotopic ossification in 4 cases,traumatic arthritis in 3 cases,sciatic nerve injury in 4 cases,femoral nerve injury in 1 case,all the nerve injury recovered in 6 months.Lower extremity deep venous thrombosis in 3 cases,all of them were recovered by given anticoagulation.No death,infection or nonunion were found.Conclusions K-L approach or ilioinguinal approach are adopted in the most of the operative treatment of acetabular fractures.Dual reconstructive plates or single.reconstructive plate combine lag screws can fix solid.It can make hip to do early exercise.

Objective To evaluate the effects of nutritional support in patients with ERCP.Methods One hundred and fourteen in patients with ERCP From Apr.2003 to Oct.2008 were reviewed retrospectively,and the clinical value and complications of nutritional support were evaluated.Results One hundred fourteen inpatients examined with ERCP,were divided into two groups;parenteral group(re = 46)and electrolytes treatment group(re = 68).There were no significant difference in length of hospital stay and postoperative complications between the two groups.Electrolytes treatment group had lower relevant hospital cost.Sixty-three patients were fasting 12 hours(eating group),and 51 patients were fasting 24 hours(fasting group).There were no significant difference in cost,length of hospital stay,postoperative complications between the two groups.Conclusions The rate of parenteral nutrition in patients with ERCP were relatively higher,the application of parenteral nutrition was unnecessarily overdose;Early enteral nutrition is safe in successful operating patients.

Maple syrup urine disease (MSUD) is an autosomally recessively inherited disorder of branched-chain amino acid (BCAA) metabolism caused by the defective activity of branched-chainα-ketoacid dehydrogenase complex (BCKD). The disease is characterized by severe ketoacidosis, mental retardation, and neurological impairments. So far, application of tandem mass spectrom-etry and HPLC has allowed newborn screening and early detection, but some patients with variant forms of the disorder will escape detection. Liver transplantation is an effective treatment. However, the rareness of liver donation limits the liver transplantation. In this review, the screening, diagnosis and therapy of MSUD will be discussed.

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.
