Methods With cluster random sampling method, 850 residents who met the selective standards were selected from four communities. Every community was divided into five districts; each district took one of intervention patterns, including health lectures, home visiting, telephone interviewing, follow-up letter, fixed-point counseling, etc. At the end of two years' intervention, all of subjects accepted the final investigation, data were collected and analyzed. Results The acceptance rates of intervention patterns were 94.0% for telephone interviewing, 89.2% for home visiting, 70.6% for health lectures, 27.2% for letter follow-up and 19.5% for fixed-point counseling. The recognition rates of manipulating these measures in medical staff were 78.9% for telephone interviewing, 70.7% for health lectures, 66.7% for home visiting, 22.2% for letter follow-up and 15.0% for fixed-point counseling. The ratio of cost to effectiveness of telephone interviewing was 1.79 which was the minimum, but the ratio of cost to effectiveness of fixed-point counseling was the maximum which was 13.79. Conclusion Health lectures, home visiting and telephone interviewing are applicable intervention measures to prevent POP in community.

Diabetic nephropathy presents an increasing trend worldwide. It has been an attractive area to find novel targets for the treatment of diabetic nephropathy. SIRT1 (Sirtuin 1), a member of deacetylation enzymes, regulates cell senescence, metabolism, and apoptosis. In last ten years, lots of studies showed that SIRT1 exerts a protective effect in the progression of the diabetic nephropathy by promoting reconstruction of energy homeostasis, modulating cell redox state, resisting cell apoptosis, inhibiting inflammation and ameliorating renal fibrosis. SIRT1 has become a potential new target for the treatment of diabetic nephropathy.

Objective To examine the cognitive function in healthy first-degree relatives (FDRs) of patients with bipolar Ⅰ disorder.Methods Cognitive function were studied in one hundred twenty healthy FDRs of patients with bipolar Ⅰ disorder and one hundred normal controls using digital symbol, digital span, visual reproduction, trail making test A (TMT-A) and trail making test B (TMT-B).Results Compared with normal controls, FDRs showed impairment in all indexes of the tests, including digital symbol, digital span (forward, reversed and forward + reversed), visual reproduction, TMT-A and TMT-B (t=-3.44、-4.23、-4.32、-4.98、-2.59、4.32、3.78, respectively, Ps≤0.01).By analysis of covariance (covariant: age and years of education), FDRs were still impaired in these indexes (P<0.05).Compared with sex-matched normal controls, male FDRs showed impairment in all indexes of the tests, but female FDRs only showed impairment in digital span (reversed, forward + reversed), TMT-A and TMT-B (P<0.05).Conclusions Attention, memory and executive function are impaired in healthy first-degree relatives of patients with bipolar Ⅰ disorder.

OBJECTlVE To study the anti-HBV activity of prepared recombinant human serum aIbu-min-interferon α-2b fusion protein(HSA-IFNα-2b) in vitro. METHODS HepG2 ceIIs were infected with recombinant adenovirus with green fIuorescence protein and 1.6-foId HBV DNA(AdGFP-HBV). The ex-pression of HBV antigens,HBsAg and HBeAg in cuIture medium was detected by ELISA assay. The tox-icity of HSA-IFNα-2b on HepG2 ceIIs was evaIuated by mTT assay.The reIative expression of HBV RNA in ceIIs and the absoIute quantity of HBV DNA in cuIture supernatant were determined by quantitative PCR assay. The activity of HBV enhancer Ⅰ was detected by DuaI-Reporter gene assay. RESULTS HBV couId repIicate and express in HepG2 ceIIs after infection with AdGFP-HBV. The expression of HBsAg and HBeAg in cuIture serum of HepG2 ceIIs infected with AdGFP-HBV decreased by 51.32%(P﹤0.01)and 50.26%(P﹤0.01),respectiveIy,when HSA-IFNα-2b 500 kU·L-1 was added. The same concentration of HSA-IFNα-2b didn't inhibit the proIiferation of HepG2 ceIIs,but inhibited HBsAg in a concentration-dependent manner. The regression formuIa between HBsAg inhibitory rate(Y)and con-centration of HSA-IFNα-2b(X)was Y=21.11 IgX+11.91(r 2 = 0.954),IC50 = 63.76 kU·L-1 . HBV RNA in ceIIs and HBV DNA in the cuIture serum decreased by 52.83%(P﹤0.01)and 53.07%(P﹤0.01), respectiveIy,when HSA-IFNα-2b 500 kU·L-1 was added. The activity of enhancer Ⅰ decreased by 40.04%(P﹤0.01)when HSA-IFNα-2b 500 kU·L-1 was added. CONCLUSlON The ceII modeI of HBV repIication for evaIuating anti-HBV agents is successfuIIy estabIished. HSA-IFNα-2b exhibits noticeabIe anti-HBV effect invitro.

BACKGROUND:Lots of bone graft materials such as autologous iliac bone, autologous rib, titanium mesh plus alograft are available in the treatment of bone defects after spinal tuberculosis debridement. OBJECTIVE: To compare the fixation effect of different kinds of bone graft materialsvia pedicle approach fixation for treatment of thoracic spinal tuberculosis. METHODS: Totaly 40 patients with thoracic spinal tuberculosis were enroled, including 18 patients accompanied with paraplegia and 15 patients accompanied with kyphosis deformity. Both of them were subjected to by standard anti-tuberculosis treatment for 2-4 weeks and consequent posterior pedicle screw fixation combined with debridement/bone grafting fusion. They were grouped by the variables of bone graft materials: autologous iliac bone, autologous rib, titanium mesh plus alograft groups. Al patients were folowed up for 24 months. The lesion healing, bone graft fusion, rehabilitation of paraplegia, correction of kyphosis and incidence of adverse reaction were observed. RESULTS AND CONCLUSION: The time of bone graft fusion in the autologous iliac bone group was shorter than that in the autologous rib and titanium mesh plus alograft groups (P < 0.05), and there was no significant difference between autologous rib and titanium mesh plus alograft groups. No adverse phenomenons such as grafts and titanium mesh faling off, fracture and displacement, nonunion and pseudarthrosis, tuberculosis recurrence were found in these three groups. After the symptomatic therapy for 3-6 months, the muscle strength of patients with paraplegia and spinal kyphosis deformity basically recovered, spinal kyphosis deformity was basically corrected. These results demonstrate that the treatment effect of autologous iliac bone is the best; however, the treatment effect of autologous rib is as good as the titanium mesh plus allograft.

To study the anticancer activities of curcumin on human hepatocarcinoma cell line Sk-hep-1 and its related molecular mechanism which has not been elucidated. In the present study,we showed that curcumin inhibited proliferation of Sk-hep-1 cells in a dose-dependent manner through MTF assay. The effect of curcumin on apoptosis in Sk-hep-1 cells was investigated by DAPI staining and the various apoptosis was observed in hepatocarcinoma cell lines Sk-hep-1, HepG2 and Hep3B, but not in normal liver cell line Chang's liver with curcumin treatment. Cell cycle analysis results showed that curcumin treatment resulted in dramatic accumulation of Sk-hep-1 cells at the G0/G1 or G2/M phase. The effect of curcumin on the expression of anti-apoptosis genes (Survivin and BCl-xL) and drug resistance genes (DRG2 and MDR1) was studied by reverse transcription-polymerase chain reaction (RT-PCR). The expression of MDR1 mRNA was significantly decreased in Sk-hep-1 cells treated with curcumin, while no alterations in the amount of DRG2 and anti-apoptosis genes' mRNA levels were found. These results indicate that curcumin is able to inhibit proliferation and induce apoptosis in Sk-hep-1 cells and it may cause by down-regulating the expression of MDR1 mRNA.

BACKGROUND: The direct ratio is formed between the size of osseous defect around implant and the required time of complete repair. It is viewed that bone implantation is suggested if osseous defect is larger than 1 mm, which benefits the bone regeneration and early fixation of implant.OBJECTIVE: To compare the effects between coralline granules and hydroxyapatite (HA) during union after immediate implantation.DESIGN: Group observation and controlled experiment was designed.SETTING: Department of Stomatology Renmin Hospital of Wuhan University.MATERIALS: HA coated implant, HA granule, coralline granule and 3adult mongrel dogs.METHODS: The experiment was performed in Department of Stomatology, Renmin Hospital of Wuhan University from August 2002 to April 2003.Under anesthesia, 6 foramens were drilled on femurs of 3 dogs (3 foramens on each side) to result in osseous defect. Coralline granules were embedded in the osseous defect around the implant in all of proximal ends (coralline granule group, CG group), HA granules were embedded in the osseous defect around the implant in all of distal ends (HA group) and nothing was embedded in the defect around the implant in the center (the control). One dog was sacrificed under anesthesia on the 2nd, 3rd and 4th months after operation successively and the samples were collected from the implanted section in each group for X-ray examination and scanning electronic microscopic observation.MAIN OUTCOME MEASURES: X-ray examination on implanted sections and scanning electronic microscopic observation on samples in each the 4th month, it was observed that implants and osseous tissue were closely integrated in CG group and HA group and there was still partial osseous on samples in each group: on the 4th month, it was discovered that the regenerated osseous tissue was matured completely in CG group and few coralline granule residue was left. In HA group, the regenerated osseous tissue was matured completely, but there was still a large amount of HA granules left and the granules had not been absorbed obviously. In the control group, the space appeared partially in the implanted cervical region.CONCLUSION: The implantation of artificial bone is suggested if the osseous defect around immediate implant is larger than 1 mm. As the implanting materials, coralline granules and HA granules act on the most advantageous guide activity. Coralline granules can be degraded and substituted with osseous tissue,but HA granules cannot be absorbed, which affects osseous reconstruction.
