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

Stasis is the critical causative factor and pathological production considered in clinic treatment. Promoting the circulation in blood vessel and removing stasis are equally important in treatment. Stasis is interactive with qi and blood. Removing stasis aims to regulating the circulation of qi and blood. Scraping therapy is one of the major approaches to stasis removal in TCM. In clinical practice, the stasis can be removed with scraping, bleeding and cupping, etc. Additionally, removing stasis with scraping should be combined with regulating qi and blood to enhance the therapeutic effect.

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.

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.

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 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 investigate the clinical significance of routine application of choledochoscope during operation of biliary duct.Methods The clinical data of 136 patients with the routine application of intraoperative choledochoscope dealing with bile duct diseases in this hospital from October 2003 to July 2009 were analyzed and summarized.Results Intraoperative choledochoscope inspection,taking stones and targeted surgery were performed in 116 cases with extrahepatic and (or) intrahepatic bile duct stones.The taking out rate of extrahepatic bile duct stones was 100% (85/85),the residual stone rates of extrahepatic and intrahepatic bile duct were 0 (0/85) and 22.6% (7/31),respectively,with the total residual stone rate was 6.0% (7/116).By using intraoperative choledochoscope,benign intrahepatic bile duct stricture was found in 13 cases,malignant extrahepatic and intrahepatic bile duct stricture in 8 cases.Four cases of hilar cholangiocarcinoma and 4 cases of common bile duct cancer,2 cases of lower segment of common bile duct polyp,3 cases of hepatolithiasis with the left hepatic bile duct carcinoma were diagnosed by biopsy via choledochoscope.Causes were confirmed by applying choledochoscope in 16 patients with obstructive jaundice.The use of choledochoscope with surgical treatment enabled benign and malignant bile duct stricture to achieve good results,without serious complications such as bile duct dilaceration,subphrenic abscess or acute cholangitis.Conclusions Using choledochoscope can tremendously reduce the residual rate of stone in biliary duct surgery,increase the definite diagnosis rate of biliary duct diseases and play a role of reasonable instruction in its treatment options.It has unique advantages in identifying causes of jaundice.It is remarkable that the role of applying choledochoscope to diagnose and cure biliary duct diseases.It should be widely used.
