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.

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.

ObjectiveTo investigate long-term effect on radiofrequency heat-coagulation (RF)endometrial ablation in treatment of anovulatory dysfunctional uterine bleeding (DUB). MethodsFrom Jul.2001 to Nov. 2009, 1 196 patients with DUB who were failed by medical treatment( including 127 patients with dysmenorrheal) were enrolled into this study in Jinan Millitary General HospitaL Those patients were divided into two groups according to age:427 patients at age of or more than 45 years (average age 48 years) in Group A who were treated by RF procedure for amenorrhea;769 patients at age of less than 45 years old (average 37 years) in group B were treated by RF for controlling excessive menstrual bleeding. All the patients had the results of menstrual score (pictorial blood loss assessment chart, PBAC), hemoglobin (Hb) ,endometrial curettage pathology and hysteroscopy examination immediately after RF procedure; Some patients still had another endometrial curettage pathology and clinical results in 6 months after RF. The mean follow-up time was 72 months ( range:6 to 100 months). The evaluation criterion for RF treatment was to use optimal and significant effect measurements. For group A, the optimal treatment effect (cure) was defined as bleeding cessation and achieving amenorrhea that continued for more than 12 months after treatment. For group B, the optimal treatment effect (cure) was also defined as bleeding cessation and resuming normal menstruation which continued for more than 12 months after treatment. Significant treatment effect was defined as irregular, minor bleeding, but PBAC score less than 100 within 12 months. If patient symptoms and PBAC scores did not change compared with those before treatment, the treatment was defined as failure. For dysmenorrhea, the optimal treatment effect was disappearance for more than 12 months, the significant treatment effect was remission, and treatment failure was not changed from the pre-treatment baseline. The effective rate was the sum of that of the optimal and significant effect. One hundred and twentyfive patients with DUB treated by agents at the same time were chosen as control group. Results( 1 ) The recent and long-term effective rates for bleeding cessation by RF: the total recent effective rates within 1 months were 94. 82％ ( 1134/1196), including 96. 5％ (412/427) in group A and 93.9％ (722/769) in group B. The total curative rates for dysmenorrheal were 82. 7％ ( 105/127 ), including 86. 4％ ( 38/44 ) in group A and 80. 7％ ( 67/83 ) in group B. Pathology examination after hysteroscopy immediately after RF showed a completely and whole destroyed endometrium in group A, and a little rested endometrium in group B. The long-term effect rates for bleeding cessation by RF after 12, 24 and 36 months were 92. 55％ (969/1047), 93.9％ (866/922) and 93.7％ (609/650), respectively. PBAC and Hb in group A and group B within 12, 24, 36 and more than 36 months were improved significantly ( P ＜ 0. 05 ). (2) Complications : the major complication was irregular minor bleeding in 1 to 2 months after treatment, the rate was 8.03％ (96/ 1196). The second one was menorrhea in 3 months after RF, the rate was 5. 18％ (62/1 196 ). This condition was corrected by the second RF. No hysterectomy was performed on those patients. Conclusion RF is the safe, efficient and minimal invasive procedure in treatment for DUB. The mechanism of keeping longterm curative effect and preventing recurrence is due to endonetrium inactivation and fibrosis by thermocoagulation.

Objective The purpose of this study is to assess the value of multi-slice spiral CT(MSCT)in the preoperative evaluation of living renal donor as a all in one modality.Methods Thirty-six potential living renal donors underwent the examination using a GE light VCT scanner.Informed consent was obtained from all participants.The plain scan,early arterial phase,late arterial phase and excretory phase scans are performed in the former 25 donors(injection rate 5 ml/s,total volume 100 ml,tube tension 120 kV).While in the later 11 donors(2 ml/s 40 ml+4 ml/s 60 ml),the scanning protocol included the plain scan(100 kV),vascular phase and excretory phase scans(100 kV).The excretory phase data were used in the reconstruction of CT urography in both groups.All images were reviewed by one radiologist and one urologist,and the findings of MSCT were compared with intraoperative findings for 33 donors,to investigate the utilities of MSCT in assessing renal vascularity,urinary tract and lesions of renal parenchyma.When discrepancies are found between the two reviewers,consensus was obtained via discussion.Au data was statiscally processed with SPSS for Windows.Results MSCT angiography is in accordance with intraoperative findings in demonstrating the anatomy of renal arteries and renal vein trunk,accesary arteries,early branching of renal artery.The findings from CTA are highly in accordance with the intraoperative findings,which facilitate intraoperative ligation and reduce relevant complications.CTU demonstrates the anatomy of urinary tract in good agreement with the intraoperative findings.The image quality of 3D vascularity and CTU between the two groups.scored 4.4±1.2 vs 4.2±1.3 and 4.6±0.8 vs 4.4±0.9 respectively,no statistical between-groups difference was found(Z=-0.89,-0.47,P＞0.05).Conclusion MSCT multiphase scanning combined with CTA and CTU play a important role in the evaluation of living renal donor,which preoperatively provide detailed information of renal vascularity,urinary tract and renal parenchyma as a all-in-one modality.
