Objective To investigate the risk factors for hip fracture in elderly people in Ningbo,in order to provide the basis for prevention and treatment of hip fracture.Methods A case-control study were conducted in study on 450 cases of hip fracture patients aged over 60 years in Ningbo and 450 subjects of control as 1 ∶ 1 matched case control study.A univariate analysis of hip fracture was performed by x2 test.Risk factors for hip fracture were analyzed by logistic regression.Results Poor self-care ability (OR=5.05),light manual labor occupation (OR=4.10),history of cerebrovascular events (OR=2.59),smoking (OR=2.14) were the risk factors for hip fracture in elderly men,while poor self-care ability (OR=11.36),light manual labor occupation (OR=2.41),osteoporosis (OR=3.19),early menopause (OR=6.89),low body mass index (OR=5.05) were the risk factors for hip fracture in elderly women.The protective factors for hip fracture was milk uptake (OR=0.29) Conclusions Early interventions for hip fracture risk factors,and prevention and treatment of osteoporosis can help reduce the occurrence of hip fracture.

Objective To investigate the influence of epigallocatechin gallate ( EGCG)on reactive oxygen species (ROS) in mouse podocytes exposed to high glucose. Methods Mouse podocytes cultured in high glucose were exposed to different concentrations of EGCG (0.2, 10, 100 μmol/L) or α-tocopherol (0.2 μmol/L) for 6, 12, 24 hours. The viability of podocytes was detected by MTT. The intracellular formation of ROS was detected by confocal microscopy with fluorescent probe CM-H2DCFDA and was measured by fluorescence microscopy. RT-PCR was used to examine the expression of p22phox, p47phox and p67phox mRNA in cultured podocytes exposed to different concentrations of EGCG. Results Intracellular ROS generation was significantly higher in high glucose than that in control conditions (P<0.01). EGCG could significantly inhibit ROS induced by high glucose significantly (P<0.01). EGCG (100 μmol/L) led to an inhibition of the increased production of NADPH oxidase components of p22phox and p67phox mRNA in high glucose (P<0.05). The expression of p47phox mRNA in high glucose was inhibited by EGCG(0.2 μmol/L) and ot-tocopherol(0.2 μmol/L) (P<0.05). Conclusion EGCG can protect cultured mouse podocytes from injury of high glucose by inhibiting ROS formation.

Objective To define the indications and evaluate the results of various surgical treatment options in patients with nonparasitic hepatic cysts. Methods The clinical data of 284 patients with nonparasitic hepatic cysts treated in our hospital from January 1995 to December 2005 were retrospectively analyzed. Results Percutaneous aspiration and sclerotherapy were performed in 161 cases and complications occurred in 9 (5.59%), recurrence in 53 (32.92%) and the mortality was 0%.Open surgery was conducted in 71 cases and the complications occurred in 16 (22.54%), recurrence in 8 cases (11.27%) and the mortality was 2.82%. Laparoscopic surgery was employed in 52 cases and complications occurred in 7 ( 13.46%), recurrence in 6 (11.54%) and the mortality was 1.92%.Conclusion There is currently no general agreement in the literature concerning when nonparasitic hepatic cysts should be treated. Laparoscopic surgery was more favorable than other therapeutic options.However, we should choose individually suitable methods according to different clinical symptom of patients.

Objective To investigate the efficacy of autologous peripheral hematopoietic stem cell transplantation in the treatment of adult dermatomyositis. Methods A 21-year-old patient with dermatomyositis received autologous peripheral hematopoietic stem cell transplantation and was followed up for 6 years. Autologous peripheral hematopoietic stem cells were mobilized by recombinant human granulocyte colony stimulating factor (rhG-CSF) before the transplantation, and the conditioning regimens consisted of cyclophosphamide,methylprednisolone and cyclosporin. Rabbit anti-human T lymphocyte immunoglobulin began to be applied on day 3 after retransfer of stem cells. The improvement in symptoms, physical signs and biochemical indicators was observed, and hematopoietic restructuration and immunity resurrection were evaluated after the transplantation. Results After the transplantation, skin eruption greatly improved and gradually subsided. The muscle force of extremities restored from level Ⅳ before transplantation to level Ⅴ. The level of creatine kinase declined sharply after transplantation, but gradually returned to previous level. Leucocyte count began to decrease on the day of retransfer, and returned to the normal level on day 8. Immune function remained normal before and after the transplantation. Conclusion Autologous peripheral hematopoietic stem cell transplantation is an alternative treatment for severe and refractory dermatomyositis.

Objective To determine the effect of lean mass and fat mass on bone mineral (BMD) in postmenopausal women of different age groups.Methods A total of 287 postmenopausal women (aged 50 years and over) participated in this study.Individuals were divided into 4 age groups by decades:group 1,50-59 yr (82 cases); group 2,60-69 yr (73 cases); group 3,70-79 yr (66 cases); group 4,80 years and over (66 cases).The BMD of lumbar spine (L2-4),left femoral neck and total hip were measured by dual-energy X-ray absorptiometry.Fat and muscle mass were analyzed by its analysis function and the percent of fat mass and muscle mass were calculated.Then data were processed by the SPSS 18.0 programme.Results One linear regression analysis showed that the L2-4 BMD was significantly associated only with body composition of trunk,while femoral neck (FN) and total hip (TH) BMD were respectively associated with body composition of different parts in group 1.L2-4 BMD was significantly associated only with trunk fat mass and muscle mass (r=0.27,0.25,both P＜ 0.05),but there were no relationships between BMD of FN and TH and body composition of different parts in group 2.The BMD of L2-4,FN and TH were significantly respectively associated with body composition of different parts in group 3 and 4.Conclusions In postmenopausal women,fat mass and muscle mass play an important role in BMD.In postmenopausal women aged 60-69 yr,the body composition has a minimal impact on BMD,and hormone replacement therapy may be the best for osteoporosis prevention and treatment in this period.Different exercise and loosing of weight in postmenopausal women of different ages can prevent osteoporosis and fragility fractures.
