Objective To establish a method for HPLC fingerprint determination of the triterpene acids in poria peel.Methods Ethanol solvent and ultrasound method were used to extract the sample. The chromatographic conditions of RP-HPLC were:acefonitrile-0.5%phosphoric acid(linear gradient elution),the detection wavelength being 242 nm, temperature at 30℃and flow rate being 1.0mL?min-1. Ten batches of poria peel produced in different places were measured.The common model was set up to calculate the correlation coefficient, cos?between every batch vector and the total standard model vector, thus to define the similarity.Results There was much difference in the constituent content of poria peel produced in different places and batches.Conlusion The HPLC fingerprint of triterpene acids is stable and reprodacible,which is useful for standard cultivation and quality evaluation of the crud drug of poria peel.

Objective To design and develop a kind of SpO2 detection and analysis system based on LabVIEW. Methods Pulse signal process and SpO2 calculation were achieved by designing a control system based on TI Company's MSP430FG439 MCU and using the digital signal process and graphic controls of the LabVIEW software. The design project and the realization way were given out by discussing the software of LabVIEW. Results The system could acquire, display and process pulse signal and calculate SpO2. Conclusion The system carries out a new way to design medical monitor equipment. Furthermore, it provides a shortcut for special analysis of the SpO2 and pulse signal in clinic.

To explore the relationships between traditional Chinese medicine (TCM) constitutional types and overweight or obesity so as to provide evidence for adjusting constitutional bias and preventing and treating obesity.

To investigate the changes of endocrine, cyclic nucleotide and immune systems in subjects of yang deficiency constitution, and to explore the relationship among characteristics and causes of yang deficiency constitution, the physiological and biochemical parameters.

Objective:To understand the information needs of patients with pituitary adenoma in different stages of diagnosis, surgery, and out-of-hospital rehabilitation, and to provide a basis for the subsequent construction of information support strategies.Methods:The qualitative research method was described. Fourteen patients who underwent primary pituitary adenoma resection in a Department of Neurosurgery in Suzhou from July 2017 to July 2018 were selected as research subjects. The confusion and information needs that occurred during the stage, and the analysis of interview data was analyzed using the content analysis strategy.Results:Five themes were extracted, "what did I get?""What should I do if I feel so uncomfortable?""Are my symptoms normal?""Should I have recovered after so long?" How to do it".Conclusions:During the diagnosis and treatment of patients with pituitary adenoma, medical staff should provide detailed and personalized information support based on general guidance and information needs that patients face at various stages.

OBJECTIVE: To analyze the clinical features of a Chinese pedigree affected with tuberculosis sclerosis and explore its molecular pathogenesis. METHODS: Clinical data of the proband and members of his pedigree were collected. Whole exome sequencing was carried out to detect variants of the TSC1 and TSC2 genes. Candidate variants was verified by Sanger sequencing and bioinformatic analysis. RESULTS: The proband and his mother, who also had mild features of tuberous sclerosis, were found to harbor a novel heterozygous c.4183C>T (p.Q1395X) variant of the TSC2 gene, which was absent in the 4 healthy relatives. Bioinformatic analysis suggested the variant to be likely pathogenic. CONCLUSION The heterozygous c.4183C>T (p.Q1395X) variant of the TSC2 gene probably underlay the disease in this pedigree. Above finding has expanded the spectrum of TSC2 gene variants. The more severe symptoms in the proband may be attributed to phenotypic heterogeneity of this disease.

Objective To observe the clinical effect of traditional Chinese medicine bone-setting technique using spinal,pelvi-lower extremity line to treat patients with knee osteoarthritis(KOA).Methods 426 patients with KOA were all from the First Affiliated Hospital of Hebei University of Traditional Chinese Medicine.They were randomly divided into experimental group(384 cases,57 cases of elimination,shedding and termination)by computer generated sequence.Traditional Chinese bone setting techniques were applied with spinal-pelvic-lower limb force line(divided into three parts:lumbar fixed point reduction method,hip joint push-pull and extension method and knee peripheral tendon recovery method every 3 days.2 weeks)treatment;The control group was the waiting treatment group(48 cases,6 cases were eliminated,abscission,termination),which was only used for clinical observation for 2 weeks.The main outcome index was WOMAC pain score.Secondary outcome measures were WOMAC stiffness score,functional score,standardized score and quality of life score(SF-12).The test time points were baseline,2 weeks after enrollment,and follow-up(14 weeks after enrollment).The control group was at baseline and 2 weeks after enrollment.Results Compared with baseline,WOMAC pain score,stiffness score,functional score and standardized score were all decreased in 2 groups 2 weeks after enrollment(P<0.05),but the experimental group was significantly decreased compared with the control group(P<0.001).SF-12 quality of life scores were all higher than before(P<0.001),but the experimental group was significantly higher than the control group(P<0.001).At follow-up,compared with 2 weeks after enrollment,WOMAC pain scores were increased(P<0.001),WOMAC stiffness,joint function and standardized scores were decreased(P<0.001),and SF-12 scores were increased(P<0.001).Conclusion The use of spinal-pelvi-lower extremity line of traditional Chinese medicine bone-setting technique in the treatment of KOA is effective in improving the knee joint function and improving the quality of life of patients,but the short-term effect of pain relief is good,and the long-term effect is not good.Its safety is good,and it can be considered in clinical application for KOA patients with joint dysfunction as the main manifestation.
