Japan’s long-term care insurance takes grassroots governments as its insurer and the elderly and part of the non-elderly as its insured;The costs is shared by government、society和individual, and is, payed through isti-tutions, communities and hothes. Since its establishment, its security level has been increasing, the role of preven-tion has been rising, the status of community-based and home-based has been highlighting, and the cooperation a-mong relevant industry has been strengthening. But at the same time, its costs was soaring during the past decade, and the continued development of the system is facing transformation pressure now. Take this as a warning, the devel-opment of long-term care in China should learn its strong points, but also try to avoid its shortcomings.

BACKGROUND:During autologous tendon grafting, the ultimate tensile strength used for suturing the end of the ligament is important for successful surgery. Improving suturing strength and increasing the number of stitches is a good choice for increasing the fixed intensity. But excess amount of stitches can produce too many thread residues, thereby affecting tendon healing.
OBJECTIVE:To investigate the essential number of suturing pins for the anterior cruciate ligament revascularization in ligament end suture fixation to reduce suturing thread exposure.
METHODS:(1) In vitro biomechanics test:12 patel ar ligament specimens were divided into two groups:the specimens were sutured with 5 or 3 stitches using Krackow suture method. The suturing thread was J&J tendon suture thread. The strength of tensile was compared between the two groups by Tensile mechanical test was conducted to compare the strength of tensile between the two groups and to explore the optimal number of stitches and suturing method. (2) Clinical application:According to the results of in vitro experiments, modified Krackow suture method was used clinical y for arthroscopic anterior cruciate ligament reconstruction in 125 cases, including 62 cases receiving 3-stitch suture, and 63 cases undergoing 5-stitch suture.
RESULTS AND CONCLUSION:The fixed strength of tensile at suture sites was over 100 N for 3-stitch double-lock suture and 110 N for 5-stitch double-lock suture. There was no significant difference in the fixed strength between the two groups, but their strength values were both over the breaking strength of suturing materials. Moreover, the fixed strength could not be reduced by suturing throughout the ligament at the first stitch. Al the 125 cases were fol owed for 6.4 months averagely, and both 3-stitch and 5-stitch suture methods achieved good outcomes. The satisfaction rate was up to 99%, and no suture breakage or loosing occurred at early and late stages. These findings suggest that, using 3-stitch double-lock suture method, a satisfactory fixed strength can be achieved with reduced thread exposure. The suturing thread can run through the ligament at the first stitch, which can reduce thread exposure but not reduce the fixed strength.

It is of great importance for surgery efficacy and avoidance of complications to reconstruct cervical curve, intervertebral height and cervical stability. Anterior cervical decompression includes discectomy and subtotal corpectomy. The former reconstruction comprises simple bone graft, bone graft with plating, cage implantation, cage with plating and total disc replacement.The latter comprises simple bone graft, bone graft with plating, titanium mesh cage with plating, conbinding cage and titanium mesh cage with plating. The common problem is loss of intervertebral height or nonunion occurring in a part of patients.Total disc replacement may preserve motion of affected levels but narrow indication. Based in the decompression, the best method should be choosen to reconstruct cervical stability and intervertebral height.

C-type natriuretic peptide (CNP) shows remarkable sequence homology to atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP) within the 17-residue ring portion formed by a pair of cysteine residues and being the third member of the natriuretic peptide family. Sequence analysis reveals that there are at least two exons in the coding region for preproCNP. Mature forms of CNP in body are CNP22 and its N-termi-nally elongated form CNP53. As an agonist, CNP selectively bind to natriuretic peptide receptor B (NPR-B) which has a single member-spanning helical domain and exert its biological effects by activating its C-teminal guanylate cyclase to catalyse formation of cyclic guanosine monophosphate (cGMP). CNP can also bind to natriuretic peptidereceptor C (NPR-C) which has high binding affinities for all of the natriuretic peptides. The synthesis and release of CNP are regulated by many cy-tokines, and CNP is metabolized by two main pathways : internalization and degradation through the binding with NPR-C or hydrolysis by neutral endopeptidase. CNP and its receptor distribute widespreadly in various tissues including vessels, blood and central neural systems, and produce effects of vasodilation, antianxiely effect and regulations of cell proliferation and endocrine.

Objective To observed the alteration of the glomerular charge-barrier (GCB) in children with idiopathic nephrotic syndrome(INS) and relationship between GCB and severity of proteinuria. Mothods The clearance ratios of pancreatic to salivary isoamylase(CPAM/CSAM) were detected in 21 cases with INS and 29 healthy controls by use of a selective inbibitor, then use the clearance ration to show the CCB. Results The ratio of CPAM/CSAM in the cases with massive proteinuria was mean 1. 18 (range 0.82 - l .54), in the cases with no-massive proteinuria was mean 2.06(1 .22 - 3. 14), in healthy controls was 3 .33 (l. 18 - 6.54). There was a significant difference in ratios CPAM/CSAM between three groups. As all cases with INS, the ratio was very significantly negatively correlated with 24-hour urine protein quantity, but not correlated when 24 hour proteinuria was in excess of 50 mg/kg. Conclusion GCB of the cases with INS is reduced, and of the cases with massive proteinuria almost dissappeared.

AIM To study the effect of antisense oligonucleotide s of telomerase on the telomerase activity and the mechanisms of its inhibiting cervical carcinoma HeLa cell line proliferation. METHODS The cytotoxic effect in vitro was determined using the trypan blue dye exclusion assay. The telomerase activity was performed by PCR-TRAP and the flow cytometry analysis was employed to investigate the effects of ASON on the cell cycle and apoptosis. RESULTS There was no significant decrease in cell viability after treated with ASON for 5 days and the ASON with FuGENE6 reduced the telmerase activity compared with the tandem primer and the empty controls. The efficancy depended on the dose of ASON and the time of treatment. ASON did not induce cell apoptisis but increased G 2/M-phase cells. CONCLUSION Antisense oligonucletides of telomerase inhibited the telomerase activity but did not induce apoptosis in HeLa cell lines .Retardation of G 2/M-phase may be the mechanism of inhibiting proliferation in HeLa cell lines.

AIM To investigate the mechanism of anti-tumor effects of curcumin on human SPC-A1 cells. METHODS Cell culture、fluorescence microscope、TUNEL method and irradiation immunity techniques were used. RESULTS ①By the action of curcumin, SPC-A1 cells grew against the wall and then peeled off gradually;fluorescence microscope showed the nucleus broke into pieces, and cell split into apoptosis bodies in different sizes; The TUNEL method further certified that apoptotic cells reached 42 67% at the concentration of 20 ?mol?L -1 curcumin at 24 h. ②The level of intracellular cAMP concentration in the SPC-A1 cells,treated with curcumin, was significantly higher than that of the control group. ③Treated with 20 ?mol?L -1 curcumin for 24 h, the expression of Caspase-8 mRNA of human SPC-A1 cells was up-regulated. CONCLUSION Curcumin can induce the apoptosis of SPC-A1 cells, and one of its molecular mechanism may be associated with the rising of the level of intracellular cAMP concentration, and up-regulating expression of Caspase-8.
