OBJECTIVE:To establish the method to control the quality of Qilian suppository.METHODS:TLC was per?formed to identify Rhizoma coptidis and Radix Notoginseng.A reverse phase HPLC-ELSD method was adopted to determine the content of ginsenoside Rg 1 and ginsenoside Rb 1 in Radix Notoginseng.RESULTS:The study on the quality control showed that the characteristic of identification by TLC was distinct and highly specific.In this quantification method,the linear ranges of ginsenoside Rg 1 and Rb 1 were1.56?g～3.74?g(r=0.9993,RSD=1.6%)and1.44?g～3.46?g(r=0.9981,RSD=1.2%)respectively.The average recovery rate of ginsenoside Rg 1 was99.10%,and RSD=1.6%(n=3);the average recovery rate of ginsenoside Rb 1 was102.13%,and RSD=1.2%(n=3).CONCLUSION:The method is simple,sensitive,accurate and re?peatable.It can be used for the quality control of Qilian suppository.

Objective To explore the incidence and significance of intra-and extraosseous edema accompanying benign tumors and tumor like diseases.Methods Imaging studies including MR,CT and plain radiograph were retrospectively reviewed in 245 cases of benign osseous tumors and tumor like diseases proved by pathology(borderline tumor,cases associated with pathological fractures,cases with lesions of skull were excluded from the study).The incidence of bone marrow and soft tissue edema were defined on T2WI with fat suppression on MRI in all the cases.x2 test was performed for the incidence rate of edema in the benign tumors and tumor like diseases.The pre-operative diagnoses were reviewed,and the influence of edema to the differential diagnosis between the benign and malignant was analyzed.Results The total incidence of bone marrow and soft tissue edema associated with benign tumors and tumor like diseases was 37.1％ (91/245),which included Langerhans cell histiocytosis 85.2％ (23/27),osteoblastoma85.0％ (17/20),osteoid osteoma93.6％ (29/31),ehondroblastoma 87.0％ (20/23).There was no statistically significant difference of edema incidence among the above-mentioned four diseases.(x2=6.35,P＞ 0.05).Both cases of endosteal capillary hemangioma had edema around.No edema was found around the lesions of other kinds of diseases.41 of 91 cases (45.1％) with edema were misdiagnosed as malignant tumor by MRI pre-operatively.Conclusion The marrow and soft tissue edema is a common sign in the benign bone tumor and tumor-like diseases,and it is frequently seen in Langerhans cell histiocytosis,osteoblastoma,osteoid osteoma,chondroblastoma.

ObjectiveTo investigate the event-based prospective memory (EBPM)and time-based prospective memory( TBPM )in stable patients with schizophrenia and to explore the relationships between prospective memory and social functioning.Methods40 schizophrenic patients and 40 normal controls matched in age,gender and education were assessed with a neuropsychological battery of tests including EBPM and TBPM tasks.The patients were also assessed with social disability screening schedule(SDSS).ResultsA statistically significant in EBPM was observed between patients with schizophrenia and normal controls (4.18 ± 1.04 vs 5.33 ±0.86,t=- 5.408,P ＜ 0.01) and the same result in TBPM ( 3.45 ± 1.48 vs 5.20 ± 0.82,t =- 6.522,P ＜ 0.01).In patients with schizophrenia TBPM was impaired more significantly than EBPM ( z=-3.238,P＜0.01 ).After controlling the total score of PANSS,the negatively correlate was showed between the total scores of SDSS and EBPM ( r =- 0.346,P ＜ 0.05 ),TBPM ( r =- 0.374,P ＜ 0.05 ) in the patients.ConclusionThe results suggest schizophrenic patients impairs both EBPM and TBPM,and TBPM is impaired more significantly than EBPM.PM shows positively correlated with social functioning moderately in the patient.

BACKGROUND: Studies on the biomechanical properties in NUSS procedure have obtained some achievements, but the effect of scoliosis surgical correction of scoliosis on thoracic deformity remains unclear.OBJECTIVE: To explore the effect of simultaneous correction of pectus excavatum and scoliosis on thoracic deformity so as to provide reference for designing a rational orthopedic scheme.METHODS: The three-dimensional reconstruction model of the chest was established based on the CT data of the patients with pectus excavatum and scoliosis. The surgical correction of pectus excavatum and scoliosis was simulated by numerical simulation method.RESULTS AND CONCLUSION: (1) Results after correction showed that the bilateral spinous processes at T3-5 segments displaced to the left (X direction) about 1 mm, suggesting that the simultaneous correction is favorable for the correction of scoliosis. (2) Compared with the single NUSS procedure, the displacement at Y direction was increased by 13.358 mm in the simultaneous correction; meanwhile, there was significant difference in the shortest displacement between two methods.(3) In views of Von Mises stress distribution, the stress in the simultaneous correction was decreased by 24.6 MPa compared with the single Nuss procedure, indicating that the simultaneous correction can significantly reduce the Von Mises stress on the chest, which contributes to alleviate the postoperative pain. (4) Our results show that the simultaneous correction cannot only improve scoliosis, but also improve the symptoms of pectus excavatum.

ObjectiveTo compare the clinical and the pathological diagnosis of elderly with dementia, assess the related factors affecting the diagnosis.MethodsThe 42 autopsied elderly patients with dementia were assessed with the National Institute for Neurological Disorders and Stroke (NINDS) criteria and the ischemic scales of Hachinski, Rosen, Loeb and Gandolfo for the clinical diagnosis of dementia. Specificity was calculated using the neuropathologic diagnosis as a gold standard.ResultsThe patients were differentiated with pathology verified Alzheimer's disease (AD), vascular dementia (VaD), and “mixed” (AD plus VaD) dementia, Parkinson's disease dementia (PDD). Comparing clinical criteria and neuropathology, the consistent rate was 80.0% for AD, 52.4% for VaD, 18.2% for AD+VaD and 0.0% for PDD. The consistent rate between 3 scores and the pathological diagnosis was about 40%～70%. There were no significant differences between the average age of onset and the survival time, and the ischemic scales of Hachinski, Rosen, Loeb and Gandolfo among the 4 types of dementia. There was no significant difference in the specificity of the NINDS criteria among the 4 types of dementia.ConclusionDementia associated with cerebrovascular disease and Parkinson's disease is the main factor affecting the diagnosis of elderly with dementia. There is no significant difference for the diagnosis of dementia among the ischemic scales of Hachinski, Rosen, Loeb and Gandolfo.

Objective To investigate the effects of pregnancy on long-term outcomes of pulmonary arterial hypertension associated with congenital heart disease (PAH-CHD).Methods Women with PAH-CHD who had undergone pregnancy under the care of Beijing Anzhen Hospital from 2004 to 2013 were retrospectively identified and 1∶1 matched to nulliparous PAH-CHD females (controls).Functional status and other clinical data were recorded for each group at baseline and follow-up.Results We successfully matched 40 pairs of pregnant and non-pregnant women with PAH-CHD.The patients were followed up for a mean of (6.5 ± 1.9) years,the outcomes of patients were documented during April 2016 to October 2016.No deaths occurred in either group during the study period.There were no statistically significant differences in long-term cardiac function between the two groups (Z =-1.41,P =0.16).After adjusting age,timing of follow-up,specific drug therapy and Eisenmenger's syndrome,pregnancy didn't have significant effect on the long-term deterioration of cardiac function in PAH-CHD patients (OR =1.32,95％ CI:0.33-5.37,P =0.70).Conclusion Pregnancy may not have significant effect on long-term cardiac function in PAH-CHD patients,but this conclusion needs to be confirmed by further studies.
