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

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 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.

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.

BACKGROUND: Dyslexia is the most common in the study of learning disabilities, it can affect various aspects of children, including behaviors,cognition, emotion, social adaptation, etc., and seriously block their obtaining of knowledge and improvement of ability in children.OBJECTIVE: To study the changing law of regional cerebral blood oxygenation in children with Chinese dyslexia in the process of recognizing Chinese characters, and investigate the neurophysiological basis of dyslexia in children.DESIGN: A case-control study.SETTING: Department of Child and Adolescent Health and Maternal Care, School of Public Health, Tongji Medical College, Huazhong University of Science and Technology.PARTICIPANTS: The study was carried out in Huazhong University of Science and Technology from June to September in 2003. Forty-five primary students of 8 to 12 years old, who were grade 3 to 5 in Wuhan city,were enrolled in this study, including 26 dyslexic children (dyslexia group)and 19 normal readers (control group). All the enrolled children were righthanded. Informed consents were obtained from all the participants and their parents (guardians) after explanation of aims and steps of this study.METHODS: The functional near-infrared imager (fNIRI) was applied to detect the changes of cerebral blood oxygenation in left prefrontal lobe of dyslexic children and normal children in the primary processing (viewing passively, reading aloud, producing an action word) and secondary processing of Chinese characters (outputting task, action words association) of Chinese characters.MAIN OUTCOME MEASURES: The changes of cerebral blood oxygenation in the primary processing and secondary processing of Chinese characters were observed in both groups.RESULTS: All the 26 children with Chinese dyslexia and 19 normal children were involved in the analysis of results. ① Changes of the contents of blood oxygenation in the primary processing of Chinese characters:When viewing the Chinese characters passively, the contents of blood oxygenation on channel A, B and C were all higher in the dyslexia group than in the control group (0.378 0, 0.134 6; 0.085 8, 0.051 9; 0.109 3, 0.069 2;P ＜ 0.05); there was no obvious difference on channel D between the two groups (P ＞ 0.05). When reading aloud, the contents of blood oxygenation on channel A, B, C and D were all unobviously higher in the dyslexia group than in the control group (P ＞ 0.05). In the process of generating action words, the contents of blood oxygenation on channels A and C were all higher in the dyslexia group than in the control group (0.411 2, 0.139 7;0.141 3, 0.078 4; P ＜ 0.05), and there were no obvious differences on channels B and D between the two groups (P ＞ 0.05). ② Changes of the contents of blood oxygenation in the secondary processing of Chinese characters: In the process of outputting task, the changes of blood oxygenation was lower in the dyslexia group than in the control group (-0.025 7, 0.089 0,F=16.25, P ＜ 0.01); In the process of action words association, the changes of blood oxygenation was obviously higher in the dyslexia group than in the control group (0.073 0, -0.072 1, F=15.59, P ＜ 0.01).CONCLUSION: The cortexes of left prefrontal lobe in dyslexic children are activated in the process of recognizing Chinese characters, but the degree and pattern of activation are different from those of normal children.The functional abnormalities of specific brain area may be the biological basis of Chinese dyslexia.Song RR, Wu HR.Changes of regional cerebral blood oxygenation in recognizing Chinese characters in children with Chinese dyslexia.

Objective To compare biomechanical performances of parallel plate fixation and vertical plate fixation for better clinical treatment of humeral intercondylar comminuted fractures (HICF).Methods Models of T-shaped fracture were created using an osteotome at the distal end of humerus in 6 specimens of upper limb in 3 human adult cadavers.The 2 fracture models of left and right humeri in the same cadaver were respectively fixated with parallel plating and vertical plating.On a biomaterial-testing machine,a vertical load was applied onto the fixated distal humerus at a speed of 5 N/s till it reached 2000 N.The loading was repeated 3 times.Vertical compression displacement,intercondylar separating displacement,deformation of medial and lateral condyles and vertical compression stiffness were documented for statistic analyses. Results Under the same load,parallel plating led to significantly less compression displacement,separating displacement and deformation of condyles( P ＜ 0.05) but significantly greater axial compression stiffness( P ＜ 0.05) than vertical plating. Conclusion In biomechanics,parallel plate fixation has better performance than vertical plate fixation for HICF.
