It was found that the Lao Shan polsaccharide P, one of the chemical components of polystictus versicolor increased the number of acetylated low density lipoprotein ( acLDL ) receptorsin the macrophages and stimulated the binding, internalization and degradation of (125I ) acLDL by the macrophages in vitro. The effect on cell degradation of ( 125I ) acLDL was dose-effect. At 100?g/ ml of the Lao Shan polysaccharide P, the effect was maximum and the degradation of ( 125I ) acLDL increased 77% ( P

BACKGROUND:The increase of serum cholesterol levels is positively correlated with the increasing incidence of osteoarthritis. Little is known about the role of high-fat diet in the degeneration of articular cartilage and induced arthritis.
OBJECTIVE:To observe the morphology change of the articular cartilage of New Zealand rabbits after high-fat diet, and explore the role of food in the articular cartilage degeneration.
METHODS:Forty New Zealand white rabbits were randomly divided into two groups. In control group, rabbits were fed with basal diet. In high-fat diet group, rabbits were fed with high-fat diet (20%lard and 80%basal diet). Fasting blood samples was taken every 4 weeks, to detect the triglyceride and total cholesterol levels. After rabbit were fed for 28 weeks, the knee joint was grossly observed and the femoral condyle cartilage was scanned by scanning electron microscope.
RESULTS AND CONCLUSION:Compared with the control group, the triglyceride and total cholesterol levels were significantly increased in the high fat group (P<0.05). Under scanning electron microscope, the high-fat group showed rough surface of condylar cartilage, shal ow pouch, messy arrangement, irregular shape and uneven size. The surface of cartilage exhibited focal denudation, irregular arrangement, uneven porosity and fractured cavity. Under higher magnification, smal mountain-like structure of cartilage surface became shal ow and flattened, the pores disappeared. Long-term high-fat diet may induce and aggravate cartilage damage, suggesting it may be involved in the pathogenesis of osteoarthritis.

Objective To explore the clinical value of colposcopy directed biopsy in diagnosis of vaginal intraepitheal neoplasia (VaIN).Methods The clinical data of 106 VaIN patients diagnosed by colposcopy directed biopsy were reviewed and analyzed retrospectively.In the past medical history of 106 patients,46 patients had cervical cancer history,43 patients had cervical intraepithehal neoplasia history,13 patients had previous hysterectomy because of benign disease and 4 patients had uncertain past medical history.Results Among 106 patients,97 patients(91.51％,97/106) had abnormal pap smears of vagina,9 patients (8.49％,9/106) had abnormal pap smears of cervix.Histological analysis revealed that 69 patients were VaIN Ⅰ,24 patients were VaIN Ⅱ,13 patients were VaIN Ⅲ.The high-risk human papilloma virus (HPV) test at diagnosis were positive in 98 patients (92.45％,98/106),negative in 8 patients (7.55％,8/106).Eighty-seven patients VaIN were localized in the upper one third of the vagina,19 patients VaIN were localized in other parts of vaginal wall.Ninety-eight patients VaIN affected to the multifocal vaginal wall,8 patients VaIN affected to the focal vaginal wall.Conclusions It has highly therapeutic value of colposcopy directed biopsy in diagnosis of VaIN.But should closely correlated to past medical history,colposcopy should performed on the whole vagina wall and multiple punch biopsy to elevated positive rate.

Objective Toinvestigatetheeffectoffolicacidonplasmahomocysteine(Hcy)levels and vascular endothelial function in elderly cerebral infarction patients with hyperhomocysteinemia. Methods Thisstudywasaprospectivecontrolledtrial.Atotalof112elderlylacunarinfarction patients with high hyperhomocysteinemia admitted to the Department of Neurology,Nanjing Municipal Government Hospital from November 2012 to October 2013 were enrolled. The patients were divided into two groups according to the method of random number table. The patients of both groups received the conventional drug treatment of ischemic stroke at the same time. Fifty-six patients were in group A,and they were treated with folic acid 20 mg,once a day;56 patients were in group B,and they did not treat with folic acid. The Hcy levels on admission and after 24 weeks treatment were measured. Brachial artery flow-mediated endothelium-dependent dilation (FMD)was measured by high resolution ultrasound,and nitric oxide (NO), nitricoxidesynthase(NOS),andendothelin(ET)weredetectedatthesametime.Results Twenty-four weeks after treatment,the plasma Hcy level in group A was significantly decreased as compared with prior treatment (12. 2 ± 4. 2 vs. 22. 6 ± 3. 7μmol/L;P<0. 05),moreover,it was lower than the level of group B at the same period (12. 2 ± 4. 2 vs. 21. 8 ± 4. 0μmol/L;P <0. 05 ). The FMD level of group A was significantly higher than that of prior treatment and group B (11. 2 ± 3. 6 vs. 9. 2 ± 3. 3,9. 3 ± 3. 3;P<0. 05). The NO and NOS levels of group A at 24 weeks after treatment were significantly higher than those of prior treatment and group B at the same period (76. 2 ± 9. 4 vs. 49. 2 ± 9. 0,50. 0 ± 9. 1μmol/L,47. 6 ± 9. 5 vs.38. 4 ± 7. 5,37. 8 ± 8. 8 kU/L;P<0.05). The ET level of group A was decreased as compared with that of prior treatment and group B at the same period (81. 3 ± 20. 5 vs. 105. 6 ± 25. 2,105. 3 ± 21. 8 ng/L;P<0.05).NoadversereactionwasfoundduringthetreatmentingroupA.Conclusion Alargerdoseof folic acid can significantly reduce the plasma Hcy level,decrease the FMD level,and ameliorate vascular endothelial function in elderly cerebral infarction patients with hyperhomocysteinemia.

The financial compensation mechanism for public county hospitals are discussed and analyzed in the paper.Such a mechanism is analyzed by means of media coverage and literature consulting,along with field survey.Roadblocks have been found in implementation of the mechanism, namely delayed payment of capital expenditure compensation,poor support for medical equipment purchase,gaps in development key disciplines development,insufficient compensation for retirees expenses,poor definition of policy-incurred losses,and unclear compensation of public health services.in a word,it is imperative to change the unreasonable financial compensation mechanism,before the six financial compensation subsidies can be fully put in place and financial compensation made efficiently.

OBJECTIVE:To investigate the effects of minocycline on clinical indexes,inflammatory factors and blood glucose of patients with moderate and severe chronic periodontitis complicated with type 2 diabetes(T2DM). METHODS:A total of 125 patients with moderate and severe chronic periodontitis complicated with T2DM selected from our hospital during Feb. 2013-Aug. 2015 were divided into control group(63 cases)and observation group(62 cases)according to random number table. Both groups were periodental non-surgical treatment as scaling and root planning. Control group was given iodine glycerin to fill periodontal pockets after surgery,2-4 times/d. Observation group was given Minocycline hydrochloride ointment,once a week,after surgery. Both groups were treated for 4 weeks. The levels of clinical indexes [probing depth,clinical attachment level(CAL),probing bleeding rate],serum inflammatory factors(CRP,TNF-α)and blood glucose(fasting blood glucose,glycosylated hemoglobin) were observed in 2 groups before treatment,3 months after treatment,and the occurrence of ADR was recorded. RESULTS:Be-fore treatment,there was no statistical significance in clinical indexes,serum inflammatory factors and blood glucose levels be-tween 2 groups(P>0.05). Three months after treatment,probing depth,probing bleeding rate and serum inflammatory factor lev-els of 2 groups were decreased significantly,and the observation group was significantly lower than the control group,with statisti-cal significance(P<0.05). Compared to before treatment,CAL of 2 groups were increased,without statistical significance before and after treatment or between 2 groups(P>0.05). The levels of fasting blood glucose in 2 groups were decreased,with statistical significance(P<0.05),but no statistical significance between 2 groups(P>0.05). Compared to before treatment,the level of glycosylated hemoglobin in control group was decreased,without statistical significance(P>0.05);the level of glycosylated hemo-globin in observation group was decreased significantly,and the observation group was significantly lower than the control group, with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between observation group (3.23%) and control group (0)(P>0.05). CONCLUSIONS:For moderate and severe chronic periodontitis complicated with T2DM,minocycline effectively improves clinical indexes of periodontitis,reduces serum inflammatory factors and blood glucose with good safety.

Objective To understand the prevalence of Toxoplasma gondii infection and its risk factors among healthy blood donation population in Shijiazhuang City,Hebei Province,so as to provide the evidence for developing effective prevention and control measures. Methods A total of 1630 cases of blood donors in Shijiazhuang City were chosen as respondents,and all the respondents were qualified to the standard of blood donation. The antibodies to T. gondii were detected by using ELISA. The in-fection rates of T. gondii in blood donation population were compared between/among different genders,ages,occupations,edu-cation levels,and places of residence. The risk factors for Toxoplasma infection were surveyed with questionnaires. Results A total of 1630 cases of healthy blood donors were investigated,and among which 126 cases were positive in the detection of anti-bodies to T. gondii and the positive rate was 7.73%. The positive rates between/among the different genders,ages,occupations, and education levels were significantly different( χ2 =4.36,13.98,9.71,7.65,respectively,all P < 0.05),and the positive rates among different places of residence were not significantly different( χ2 =1.63,P>0.05). The questionnaire survey showed that the T. gondii infection was closely related to keeping pets,outside eating frequently,having chafing dish or barbe-cue,sharing cutting board for cooked and uncooked food,and no the habit of washing hands before meals. Conclusions The infection rate of T. gondii is relatively high among the healthy blood donation population in Shijiazhuang region. The cognitive ed-ucation for T. gondii infection and infection monitoring are the keys to avoid the transfusion infection.

Objective To discuss the clinical feature of cholestasis preterm infants who have used parenteral nutrition early after birth,and analyze the relative factors and preventive meatures of parenteral nutrition associated cholestasis (PNAC).Methods We retrospectively analyzed the preterm infants who were born and hospitalized at Shengjing Hospital of China Medical University from January,2011 to April,2016.There were 89 cases in total that used at least 2 weeks of parenteral nutrition in the early stage after birth and were developed to cholestasis afterwards.We divided 89 cases into PNAC group and multifactor group:the former was corresponded to PNAC diagnosis standards,accounting for41 cases (46.07％);the latter with other etiology in addition to parenteral nutrition accounts for 48 cases.The clinical characteristics were studied and analyzed using case-control method.Results The sex ratio of premature cholestasis was 2.18:1,the mean gestational age was (31.05 ±2.15) weeks,the mean birth weight was (1360.55 ±421.14) g,and the mean using-time of parenteral nutrition was (26.22 ± 9.78) d.Futhermore,PNAC group was divided into hepatitis group and non-hepatitis group according to the alanine aminotransferase level,and they both had statistical significance in gestational age,starting time of parenteral nutrition,appearance time of jaundice,enteral feeding time,starting dose of amino acid,maximum dose of fat emulsion (P ＜ 0.05).We divided them into long-term group (≥20 d) and short-term group (＜ 20 d) according to the using time of parenteral nutrition.The level of alanine aminotransferase,glutamic oxalacetic transaminase,total bilirubin,direct bilirubin and bile acid of longterm group was higher than those of short-term group,but with P≥0.05.The multifactor group was mostly accompanied with multiple infections in the order of bacterial infection (75.0％),fungal infection (20.83％),cytomegalovirus infection (8.33％) and syphilis infection (2.08％),etc.The other complication's incidence rate of PNAC group and multifactor group had no statistical significance.In terms of prognosis,the liver function of two group improved remarkably than before,with PNAC group having more significance (P ＜0.05).Conclusion PNAC is the major factor of preterm cholestasis,and the degree of liver damage of PNAC preterm was related to starting time of parenteral nutrition,using time of parenteral nutrition,enteral feeding time,starting dose of amino acid and maximum dose of fat emulsion.The liver function of PNAC group is recovered obviously through regulatory treatment,and it possesses a better prognosis than multifactorgroup.

Objective To compare the safety and effectiveness of temporary occlusion techniques with different balloons in performing cesarean section for patients with pernicious placenta previa.Methods The clinical data of 15 patients with pernicious placenta previa,who received cesarean section during the period from March 2014 to April 2016,were retrospectively analyzed.In order to reduce bleeding during operation and to preserve the uterus as far as possible,temporary occlusion of abdominal aorta with balloon was adopted in 7 patients (group A),and temporary balloon occlusion of bilateral internal iliac arteries was employed in 8 patients (group B).The intraoperative radiation dose,the amount of blood loss and blood transfusion during cesarean section,the hysterectomy rate,the postoperative hospitalization days,and the intervention-related complications were documented,and the results were compared between the two groups.Results All the 15 patients were suffered from central type of placenta praevia complicated by extensive placenta accreta.With the help of temporary balloon occlusion technique,the cesarean section was successfully accomplished in all 15 patients.Subtotal hysterectomy had to be done in 7 patients,including 4 patients of group A and 3 patients of group B,and every one patient from each group developed arterial thrombosis of lower limb.The intraoperative radiation dose of group A was significantly lower than that of group B (P＜0.01),besides the amount of blood loss and blood transfusion during cesarean section,the hysterectomy rate,the postoperative hospitalization days,and the intervention-related complications of group A were all lower than those of group B,but because of the limited number of cases these differences were not statistically significant (P＞0.05).Conclusion For the treatment of pernicious placenta previa,temporary balloon occlusion technique-assisted cesarean section is safe and effective.The intraoperative radiation dose in the group using temporary balloon occlusion of abdominal aorta is remarkably lower than that in the group using temporary balloon occlusion of bilateral internal iliac arteries.

The paper analyzed the compensation mechanism applied in public hospitals in different localities in China,which are currently experimenting with the zero price margin for drugs.It also introduced the revenue variations resulting from this practice.It is discovered that public hospitals can hardly make their ends meet with merely governmental financial input,and that lowered income of doctors and price distortion arc evident in those experimental hospitals,with little progress in overcoming the subsidization of medical services with drug sales.The authors recommended a comprehensive reform,the mechanism of diversified health input,change of internal incentive mechanism within the hospital,improvement in the healthcare service pricing mechanism,and exploration of new operation mechanisms for public hospitals.
