Three new points of view were reported in this study:1.Found out the distribution of KaschinBeck disease (KBD) in Tibet,the complexity of bone disease composition,and the types of osteopathy coexisted which need to be identified;2.The clinical symptoms of KBD in Tibet were significantly different from those in other areas of our country;3.The new clinical subtypes of KBD were found in Tibet,which had humeral shortness and short stature,but with normal hands and feet.This discovery made us understand KBD more profoundly and comprehensively,and promoted the research and prevention work of KBD.

To discuss the availability of evaluation on the dissolution studies of the multicomponents in traditional Chinese medicine, the in vitro dissolution of total composition of the tablet of rhizomes of Ligusticum chuanxiong components and its correlation with the in vivo were studied by the method of area under the absorbance-wavelength curve (AUAWC). Taken the tablet of rhizomes of Ligusticum chuanxiong components which is composed of sodium ferulate and ligustrazine hydrochloride as subject model, the dissolution tests were carried out with basket method. The plasma concentrations of tablets in different rats were determined by AUAWC at different interval times. The in vivo absorption percentage was calculated by Wagner-Nelson equation to evaluate the in vitro and in vivo correlation. According to the results, the cumulative dissolution in vitro of total composition of tablets of rhizomes of Ligusticum chuanxiong components at 60 min was 90.65% in water by AUAWC. The in vivo pharmacokinetics is fitted with an one-compartment model. The linear equation based on the cumulative dissolution rate (fr) and absorption percentage (fa) at 5, 10, 20, 30 and 60 min was fa = 0.819 7 fr+0.183 and the correlation coefficient was 0.959 5, which showed a good correlation between the in vitro dissolution and the in vivo absorption percentage. The method of AUAWC can be used accurately, feasibly and conveniently to evaluate the in vitro and in vivo correlation of total composition of tablets of rhizomes of Ligusticum chuanxiong components, which will provide better guidance to study the in vitro and in vivo correlation of sustained release preparation etc under complex system of traditional Chinese medicine in the future.

In order to improve the accuracy of blood pressure measurement in wearable devices, this paper presents a method for detecting blood pressure based on multiple parameters of pulse wave. Based on regression analysis between blood pressure and the characteristic parameters of pulse wave, such as the pulse wave transit time (PWTT), cardiac output, coefficient of pulse wave, the average slope of the ascending branch, heart rate, etc. we established a model to calculate blood pressure. For overcoming the application deficiencies caused by measuring ECG in wearable device, such as replacing electrodes and ECG lead sets which are not convenient, we calculated the PWTT with heart sound as reference (PWTT(PCG)). We experimentally verified the detection of blood pressure based on PWTT(PCG) and based on multiple parameters of pulse wave. The experiment results showed that it was feasible to calculate the PWTT from PWTT(PCG). The mean measurement error of the systolic and diastolic blood pressure calculated by the model based on multiple parameters of pulse wave is 1.62 mm Hg and 1.12 mm Hg, increased by 57% and 53% compared to those of the model based on simple parameter. This method has more measurement accuracy.

Objective To analyze the relationship between dynamic change of GPI-80 and disease severity and prognosis of childhood anaphylactoid purpura. Methods Patients were collected and divided into three groups according to their clinical features: purpura group (purpura only), mixed group (purpura + arthritis + gastrointestinal bleeding) and nephritis group. There were 20 patients in each group. GPI-80 expression on the neutrophils was detected by flow cytometry during acute and regressive phases of the disease. GPI-80 expression was compared among different groups and different phases. Renal biopsies were performed in 20 nephritis patients. Results GPI-80 expression was significantly increased in all patient groups compared with that in the normal control (P 0.05). No significant difference of GPI-80 expression was found among 20 nephritis patients with different pathological patterns. Forty-two patients (10 in purpura group, 15 in mixed group, and 17 in nephritis groups) were followed up and GPI-80 expression was detected at the time of discharge and 2 weeks after discharge, the results showed that GPI-80 expression was decreased from 93.26% (?7.89%) at acute phase to 91.37% (?6.9%) at regressive phase with an average interval of 13.5 days. Most of them (35/42) further decreased to 38.44% (?7.8%) in 2 weeks after discharge. GPI-80 expression remained high in 7 patients for 2 weeks after discharge and relapsed in 5 patients within 1 month after discharge. Conclusions High GPI-80 expression is related to the severity of the disease. The decrease of GPI-80 takes place later than the improvement of clinical symptoms. Children with persistently high GPI-80 expression are likely to relapse. It seems that there is no correlation between GPI-80 expression and different pathological patterns of nephritis.

Aflibercept is a soluble fusion protein which combines ligand-binding elements taken from the extracellular components of vascular endothelial growth factor (VEGF) receptor-1 and receptor-2 fused to the Fc portion of IgG,and it is a novel antiVEGF drug,which can reduce vascular permeability and inhibit neoangiogenesis by binding VEGF tightly.A large number of phase Ⅲ clinical trials have demonstrated the satisfactory outcomes of aflibercept in the management of neovascular age-related macular degeneration,macular edema secondary to retinal vein occlusion or macular edema and other retinal vascular diseases.Moreover,intravitreal injection of afiibercept can improve the visual acuity and attenuate the fundus lesion,which provides a new drug option for physicians.The review will summarize the chemical properties of aflibercept and its application,safety and efficacy of aflibercept for the treatment of retinal vascular diseases.

Objective To investigate causes and treatment approaches for postoperative complications after laparoscopic adjustable gastric banding(LAGB).Methods Clinical and follow-up data of 302 cases were reviewed.The body mass index (BMI),percent excess weight loss (％ EWL),operation time,intraoperative blood loss,the incidence of complications and management were analyzed and summarized.Results There were no conversion to open surgery.The overall complication rate was 6.29％ including 2 cases of gastric wall injury,5 cases of gastric banding slippage (recovered by reoperation).There was no gastric parietal banding corrosion,tube bursting leakage,pulmonary embolism,micronutrient deficiencies,nor mortality.Conclusions The majority of patients were satisfied with the operation effect,still,there were substantial postoperative complications including gastric wall injury,gastric banding slippage.

This study was aimed to observe the effect of Tao-He Cheng-Qi Decoction (THCQD) on tissue injury of different organs among rats with sepsis. A total of 100 Kunming male SD rats of clean grade were randomly divided into five groups, which were the normal control group, model 6 h control group, model 12 h control group, THCQD 6 h group and THCQD 12 h group. The normal control group received no treatment. The classic CLP method was ap-plied in the establishment of sepsis rat model in other groups. Intragastric administration of saline 1 ml/100 g (weight) was given to each rat in the model group every day. Intragastric administration of THCQD 1 ml/100 g (weight) was given to each rat in the THCQD group every day. The model was established after 7 days. Tissue speci-mens of lung, heart, kidney, liver, and small intestine were collected at 6 h and 12 h after modeling, respectively. Pathomorphological changes of each group were observed by light microscopy and electron microscope. The results showed that compared with the model group at the same time point, pathomorphological changes of tissues of the lung, heart, kidney in THCQD group were not significant. However, pathomorphology of tissues of the liver and small intestine changed significantly in the THCQD 12h group. And there were statistical differences (P < 0.05) between two groups in the score of pathomorphology. It was concluded that THCQD had protective effect on tissues of the liv-er and small intestine among rats with sepsis. However, the mechanism is not clear and requires further research.
