With attributes of both public sector industries and the market and asymmetry of information between the government and medical institutions and between doctors and patients, the medical industry cannot develop healthily if it relies simply on market mechanisms. Thus, government regulatinn. necds to be adopted. The author analyzes the state of government regulation in the domestic medical industry by giving an account of its connotations and development history and argues that only by adopting incentive regulation and perfecting the medical charging system, the medical quality evaluation system and the medical legal system can effective regulation of medical costs, medical impartiality and effectiveness, and highly efficient, fair and orderly development of the medical industry be ensured.

0.05).But it showed significant higher level in moderate and severe PIH patients than the normal ones. (prepartum. 1195?72、1206?96 vs 1102?89, intrapartum, 1256?81、1308?84 vs 1174?86). The concentration of IECa 2+ has positive relationship with MAP in PIH patients. Conclusions The best method to decrease the harmfulness of overload IECa 2+ is to normalize its level by effective measure of decrease the blood pressure.

BACKGROUND:Studies have shown that polyethylene polymer-synthesized ureteral stents have good biocompatibility in vivo, but the side effects are found to induce the body to produce inflammatory, pyrogenic, and al ergic reactions. Therefore, studies have mainly aimed to explore the biocompatibility, toxic and side effects, inflammation of newly developed ureteral stents synthesized by L-lactic acid, glycolide, and barium sulfate. OBJECTIVE:Based on the biocompatibility comparisons on cel toxicity test, inflammatory reaction, al ergic reaction, pyrogen reaction and mortality after implantation between the usage of polyethylene material and L-lactic acid, glycolide, barium sulphate syntheses, to provide a better reference to introduce a new clinical ureteral stent material. METHODS:There were three groups in the experiment:blank control group, new material group, polyethylene group. Cel s were cultured in normal medium, leach liquid of L-lactic acid, glycolide, barium sulphate syntheses and leach liquid of polyethylene, respectively. RESULTS AND CONCLUSION:The toxic effects were significantly enhanced in the urethral epithelial cel s that grew in the leach liquids of two materials compared with the blank control group (P<0.05), but the two kinds of materials had no significant statistical difference in the toxicity test (P>0.05). Hematoxylin-eosin staining results showed that there were obvious inflammatory infiltrations in muscle tissue and the number of neutrophils and eosinophils were increased when the two kinds of materials were implanted in the rats for 2 and 6 weeks (P<0.05), but the inflammatory infiltration and tissue damage in the new material group was less than that in the polyethylene group (P<0.05). ELISA results showed that the serum concentrations of interleukin-10 and interleukin-23 were significantly increased when the two kinds of materials were implanted in the rats for 6 weeks (P<0.05), but the content of inflammatory cytokines in the new material group was less than that in the polyethylene group (P<0.05). In the new material group, there was only one rat that developed al ergic reaction and there was no pyrogen reaction or death;however, in the polyethylene group, there were three rats with presence of al ergic reaction and one rat with pyrogen reaction but no death. These findings indicate that the new ureteral stent material synthesized with L-lactic acid, glycolide and barium sulphate can reduce inflammation reactions, al ergic reactions and pyrogen reactions to the body, and has better biocompatibility than polyethylene composite material.

Objective To explore effect of diosmin on serum and prostatic fluid immune mediated factors and clinical effect in patients with chronic prostatitis.Methods 89 cases of old male patients with chronic non bacterial prostatitis were selected, and divided into two groups.The control group were treated with universal tablets, the experiment group were treated on the base of the control group with diosmin.12 weeks as a course.Clinic effect, adverse reaction rate, prostatic fluid MIP-2 and MIP-1αwere compared after treatment.Results Compared with control group, MIP-1αand MIP-2 in serum and prostatic fluid were lower(P<0.05),NIH-CPSI score and QOL scores were lower(P<0.05), total effective rate was higher than control group(P<0.05),the incidence of adverse reactions was lower(P<0.05).Conclusion Diosmin can reduce MIP-1α, MIP-2 in serum and prostate fluid of patients with chronic none bacterial prostatitis, and improve the pelvic pain, dysuria, sexual dysfunction and other symptoms, and has less adverse reaction.

0.05). Conclusions GSTM1 (0/0) gene polymorphism may be linked to prostate cancer risk and early onset age in Chinese men.There is no significant association between CYP1A1 gene polymorphisms (m1 and m2 genotypes) and prostate cancer risk.

BACKGROUND: The aseptic loosening of prosthesis has become one of the most obvious matters after operation of prosthesis replacement. OBJECTIVE: To verify the effect of ibandronate on early fixation of implants by local application. METHODS: Forty-four Zelanian rabbits were used in the experiment. A standard animal model of the rabbits' both tibia was embedded with metal screw into the proximal end. Ibandronate at 1 mg/L was sprinkled locally in the left tibia of every rabbit (experimental group), while saline solution was given in the right tibia (control group). (P < 0.001). These findings indicate that, local application of ibandronate solution can obviously promote new bone formation at the earlier period, improve early fixation of implants and decrease the incidence of aseptic loosening of prosthesis.
