Objective To explore aspirin resistance (AR) and its relevant influencing factors in patients on maintenance hemodialysis (MHD).Methods Patients on MHD who visited Beijing Chaoyang Hospital from June 1 to 30,2011 were enrolled in this study.A total of 150 age and gender matched individuals with normal renal function were taken as control group.Anthropometric data,biochemistry parameters,ultrasonography and thromboelastograph (TEG) were inspected in the both groups.AR was defined as inhibiting rate of acetylsalicylic acid drugs [MA (AA)] ＞ 50％ by TEG.Results Among the total 391 patients on MHD,hypercoagulation was found in 18 patients (4.6％),nomal coagulation in 288 patients (73.7％) and hypocoagulation in 85 patients (21.7％).Pearson's correlation analysis revealed that the reaction time (R) and the thrombus maxithrombelastic degree (MA) values were not correlated with the levels of hemoglobin and platelet in MHD patients.A total of 306 patients with hypercoagulation and normal coagulation were chosen as the MHD group.Compared with the control group,higher high sensitivity C reactive protein (hsCRP),homocysteine (Hcy) and R value were observed in the MHD group (P ＜ 0.05),while MA was significantly lower in the MHD group.Statistically higher incidence of AR was shown in the MHD group (48.0％ vs 20.0％,P =0.00).Patients in the MHD group were divided into the AR group and the aspirin sensitive (AS) group by the result of TEG.Compared with the AS group,patients in the AR group were found to be older with a higher female/male ratio,longer dialysis sustained time,higher ratio of diabetes history,higher hsCRP,Hcy and fasting blood glucose (FBG) and MA.They also manifested a higher incidence of cardiovascular and cerebrovascular diseases,peripheral vascular disease and arteriovenous fistulas with thrombosis with more spots of carotid artery and higher intima thickness of carotid artery (IMT) (all P values ＜0.05).Lower R value was shown in the AR group.Binary logistic regressive analysis revealed that the ratio of diabetes history,age and dialysis sustained time.Hcy and hsCRP were the independent risk factors for AR in patients on MHD.A total of 289 patients on MHD with atherosclerosis were followed up for the mean time of 18.0 months with no hemorrhage found in the process.Cox proportional hazards regression modeling demonstrated that AR was associated with the major adverse longterm outcome of the vascular events [HR =0.40,95 ％ CI 0.29-0.72,P =0.00].Conclusions The ratio of platetet activation in patients on MHD is significantly lower than in those with normal renal function.Small dose of aspirin could be prescribed for the patients on MHD with atherosclerosis to prevent vascular events.The incidence of AR is 48.0％ in the MHD group and the independent risk factors for AR in MHD patients are the ratio of diabetes history,age,dialysis sustained time,Hcy and hsCRP.AR is associated with the major adverse long-term outcome of acute vascular events.

Objective To observe the effect of Acupoint Thread Embedding on the motor function of children with cerebral palsy. Methods90 children with cerebral palsy were divided into 2 groups by the visiting time and gender: the observation group accepted AcupointThread Embedding and comprehensive rehabilitation while the control group accepted comprehensive rehabilitation only. They were assessedwith Gross Motor Function Measure before and 3 months after treatment. Results The incidence of efficiency was 95% in the observationgroup and 80% in the control group (P<0.01). The score of Gross Motor Function Measure was higher in the observation group thanin the control group (P<0.01). Conclusion Acupoint Thread Embedding can promote the motor functional recovery of children with cerebralpalsy.

Aim: To establish the metabolic fingerprint and profile of bioactive components in human plasma after sublingual administration of compound Danshen dripping pills. Methods: Human plasma samples were collected at different time intervals. Powerlab tension system was used to measure their ability of expanding blood vessel and column switching system was employed to purify and enrich the components of interest. Results: The plasma sample of 1.5h had the strongest ability for expanding blood vessel, and had five new peaks in the chromatogram. Conclusion: After being identified, the intensity ratio of these 5 peaks was calculated. The diagram called metabolic profile was established to link bioactive compounds with pharmacodynamic action.

OBJECTIVETo research the germplasm resources and the contents of senegenin in processing products of Polygala tenuifolia.

METHODThe contents of senegenin in wild Polygala tenuifolia and cultivated samples of Polygala tenuifolia were determined by RP-HPLC, and compared.

RESULTThe contents of senegenin in wild reduce gradually along Shaanxi, Shanxi, Hebei to Dongbei. The contents of senegenin in cultivated three-year samples of three year Polygala tenuifolia from five main place was similar, 0.44%-0.49%. The content of senegenin were 0.44%-0.64% in the wand and 0.03%-0.09% in the residual part of stem, and the content of senegenin in Polygala tenuifolia was more than that in processing products.

CONCLUSIONThere is a correlation between the content of senegenin in Polygala tenuifolia and ecology environment that show a is inverse proportion with the quality grade, and the contents in the processing products were decreased. Senegenin can be used as a characteristic marker in range. This research provides a reference for search a index for quality control of Radix polygala and its processing products.

Ackerman's pattern analysis is an epoch-making leap in the diagnosis of dermatopathology,which embodies a profound understanding of the whole dermatovenereology.To improve the teaching quality of Dermatovenereology for five year clinical medical students,pattern analysis is introduced into course educational practice,and the diseases that scattered throughout the whole textbook and listed in various chapters or sections are reclassified according to its pathological features.Thus the organic connection of related knowledge points and the lateral contrast network between different diseases is constructed by the central tache of dermatopathology,and therefore makes the course more logical and be more beneficial for the undergraduate students to learn and to remember.By the way,the thinking method of pattern analysis will also be an implicit teaching content and imperceptibly instilled to the undergraduate students,and inspired potential and motivation and aroused learning interest,expanded thought train ability to pursue advanced and further studies.

Objective: To discuss the surgical technique of lateral unicondylar knee replacement (UKR) for patients with lateral compartment osteoarthritis and evaluate its recent clinical efficacy. Methods: A retrospective analysis was conducted on 22 cases of lateral compartment osteoarthritis patients receiving lateral UKR at Orthopedic Department, Beijing Chao Yang Hospital, Capital Medical University from January 2016 to January 2019.There were 8 males (8 knees) and 14 females (14 knees), aged 65.7 years(range: 54 to 83 years).All patients completed preoperative imaging examination and excluded extra-articular deformity.Lateral parapelatellar approach was used for the operation and the tibial osteotomy was performed by extramedullary positioning.The residual cartilage of the external condyle was removed by pendulum saw to subchondral bone.Appropriate prosthesis were selected, and the tightness of the gap and the stability of the joints were repeatedly confirmed during the operation.The postoperative complications and the results of physical and imaging examinations were collected.The preoperative and postoperative Oxford knee Score (OKS) and knee society score (KSS) of patients were recorded and compared by paired t test. Results: All patients were followed up for 24.6 months (range: 8 to 40 months).No complications such as incision exudation, skin necrosis and deep venous thrombosis of lower limbs were found after the operation.No cases of prosthesis loosening, excessive wear of pads, dislocation and postoperative infection were found at the last follow-up.The OKS decreased from 46.5±3.1 preoperative to 22.4±3.3 postoperative(t=13.4, P=0.00) and KSS improved from 69.5±8.7 preoperative to 90.2±7.4 postoperative (t=16.9, P=0.00) . Conclusions For the treatment of lateral compartment osteoarthritis, UKR has the advantages of rapid recovery of knee function, less complications and less trauma.The short-term efficacy is satisfactory, but the long-term efficacy remains to be observed.

Objective: To evaluate clinical treatment efficacy of double-row fixation with bridging suture anchors for chronic, severe patellar tendinopathy. Methods: A retrospective study of 18 patients suffered from severe patellar tendinopathy and underwent surgical treatment during January 2009 and June 2014 at Department of Orthopedic, Beijing Chao Yang Hospital, Capital Medical University was conducted. All patients had received conservative therapy for more than 6 months(range: 6-30 months) but the effect was unsatisfactory. There were 10 males (12 knees) and 8 females (12 knees)with age of 47.2 years(range: 32-63 years). Seven cases on the left and 17 cases on the right. The surgical treatment included a midline incision at patellar tendon, complete debridement, and double-row fixation with bridging suture anchors. Visual analogue scale(VAS), Lysholm score were collected preoperatively and postoperatively, and compared by paired-t test. The postoperative complications was recorded. Results: All patients were followed up for 35.7 months (range:24-64 months) without any dropout.VAS decreased from 7.5±1.6 preoperative to 1.4±1.0 (t=4.45, P=0.00) postoperative, Lysholm score increased from 48.3±5.2 to 89.6±5.4 (t=-4.88,P=0.00).The Lysholm score was excellent in 3 cases and good in 15 cases.No patellar tendon rupture or suture fixation failure was recorded during the follow-up period. Conclusions The effect of double-row fixation with bridging suture anchors is satisfactory with few postoperative complications.It can not only improve clinical symptoms of patients, but also restore knee joint function.
