Pi-dan is a signifi cant conception,which comes from Inner Canon of Huangdi.From the vivid description of Pi-dan in Inner Canon of Huangdi,we consider that the formation and process of Pi-dan is equivalent to metabolic syndrome.They are have the same etiological factor:obesity,the same pathogenesis:abdominal fullness and interior heat,and they can result in diabetes,hypertension,hyperlipidemia,fat liver,gout and a series of severity vascular complication.The theory of Pi-dan exactly points out that obesity the original cause of metabolic syndrome,and suggests that early prevention and treatment for obesity is an important method to prevention metabolic syndrome and its complications.The main pathogenesis of Pi-dan is abdominal fullness and interior heat,and the main therapeutic methods are Xiaogaojiangzhuo,Kaiyuqingre,and Huoxuetongluo.

Objective :To explore the feasibility and clinical value of real time three‐dimensional transesophageal echo‐cardiography (RT‐3D TEE) in diagnosis of congenital heart valvular disease (CHVD).Methods :A total of 135 CH‐VD patients treated in our hospital were selected .All patients received surgery ,and transthoracic echocardiography (TTE) and RT‐3D TEE inspection successively within 7d before surgery .Heart valve lesion condition was observed , and diagnostic results of two methods and surgical outcome were compared and analyzed .Results :RT‐3D TEE could display the morphological structure ,lesion degree and peripheral blood flow of heart valves in CHVD patients in a multi‐angle ,stereoscopic and clear way .It could find heart valve disease which is difficult to be identified by TTE , and corrected the diagnostic deviation .With surgical results as the gold standard ,diagnostic coincidence rate of RT‐3D TEE was significantly higher than that of TTE (97. 04% vs.91. 11%, P＝0.039).CHVD diagnosed by RT‐3D TEE and TTE possessed a intermediate consistency (Kappa＝0.477 , P＝0. 001).Conclusion :RT‐3D TEE can pro‐vide more imaging information for the diagnosis of CHVD ,which can be used as an effective supplement for preop‐erative TTE examination .

Objective: To observe the clinical efficacy of mind-refreshing and balance-restoring needling method combined with Frenkel exercises in treating ataxia after cerebral stroke. Methods: The recruited 120 patients were randomized into an observation group and a control group, with 60 cases in each group. The control group was intervened by mind-refreshing and balance-restoring needling method, while the observation group was given additional lower-limb Frenkel exercises. Before and after treatment and at the follow-up, the ataxic lower-limb function was scored using Berg balance scale (BBS) and international cooperative ataxia rating scale (ICARS), and Barthel index (BI) was adopted to score the activities of daily living (ADL). Results: After treatment, the markedly effective rate was 70.2％ and the total effective rate was 96.5％ in the observation group, versus 39.7％ and 87.9％ in the control group, and the differences in the markedly effective rate and the total effective rate were statistically significant (P<0.01, P<0.05). The intra-group comparisons showed that the BBS, ICARS and BI scores after treatment and at the follow-up were significantly different from those before treatment in both groups (all P<0.01).There were significant differences in the BBS score between the two groups after treatment and at the follow-up (P<0.05, P<0.01); the between-group differences in the ICARS and BI scores were statistically insignificant after treatment (both P>0.05), while the between-group differences in the ICARS and BI scores were statistically significant at the follow-up (both P<0.05). The interaction effects between the scoring time of BBS and BI and the group factor were statistically significant (P<0.01, P<0.05). Conclusion: Mind-refreshing and balance-restoring needling can effectively improve the lower-limb ataxic symptoms and ADL after stroke; when combined with Fenkel exercises, this needling method can produce more significant efficacy.

Neuroglobin (Ngb) is a respiratory protein that is preferentially expressed in brain of mouse and man. In this article, Tibetan antelope, living at altitude of 3 000-5 000 m for millions of years, was selected as the model of hypoxia-tolerant adaptation species. Using reverse transcription polymerase chain reaction (RT-PCR) and Western blot techniques, expression of Ngb gene was amplified and analyzed in antelope brain tissue. Our results showed that Ngb homology protein in Tibetan antelope was identified with more sequence similarity with cattle (96%), sheep (95%), and human (95%). We detected that there were some mutations occurred in the Open Reading Frame of Ngb in Tibetan antelope compared with sheep. Phylogenetic analysis of Ngb chain showed that it was closer to cattle than the others. This study suggests possible roles of central nervous system enriched Ngb in adaptation of Tibetan antelope to extremely high altitude.

BACKGROUNDHyperparathyroidism (HPT) occurs at an early age and has a high disability rate. Unfortunately, confirmed diagnosis in most patients is done at a very late stage, when the patients have shown typical symptoms and signs, and when treatment does not produce any desirable effect. It has become urgent to find a method that would detect early bone diseases in HPT to obtain time for the ideal treatment. This study evaluated the accuracy of high field magnetic resonance imaging (MRI) combined with spiral computed tomography (SCT) scan in detecting early bone diseases in HPT, through imaging techniques and histopathological examinations on an animal model of HPT.

METHODSEighty adult rabbits were randomly divided into two groups with forty in each. The control group was fed normal diet (Ca:P = 1:0.7); the experimental group was fed high phosphate diet (Ca:P = 1:7) for 3, 4, 5, or 6-month intervals to establish the animal model of HPT. The staging and imaging findings of the early bone diseases in HPT were determined by high field MRI and SCT scan at the 3rd, 4th, 5th and 6th month. Each rabbit was sacrificed after high field MRI and SCT scan, and the parathyroid and bones were removed for pathological examination to evaluate the accuracy of imaging diagnosis.

RESULTSParathyroid histopathological studies revealed hyperplasia, osteoporosis and early cortical bone resorption. The bone diseases in HPT displayed different levels of low signal intensity on T(1)WI and low to intermediate signal intensity on T(2)WI in bone of stage 0, I, II or III, but showed correspondingly absent, probable, osteoporotic and subperiosteal cortical resorption on SCT scan.

CONCLUSIONHigh field MRI combined with SCT scan not only detects early bone diseases in HPT, but also indicates staging, and might be a reliable method of studying early bone diseases in HPT.

Energy metabolism plays an important role in life survival for species living in high altitude hypoxia condition. Air-breathing organisms require oxygen to create energy. Tibetans are the well-adapted highlanders in Qinghai-Tibetan Plateau. It was thought that different metabolic approaches could lead to different adaptation traits to high altitude hypoxia. Recently identified hypoxia inducible factors pathway regulators, endothelial PAS domain protein1 (EPAS1)/HIF-2a and PPARA, were involved in decreasing hemoglobin concentrations in Tibetans. Because EPAS1 and PPARA also modulated the energy metabolism during hypoxia, we hypothesized that positive selected EPAS1 and PPARA genes were also involved in unique energy metabolisms in Tibetans. In this brief review, we take a look into genetic determinations to energy metabolisms for hypoxia adaptations traits in Tibetans and mal-adaptive conditions such as high altitude diseases.

Objective To systematically review and synthesize the lived experience of family members caring for schizophrenia patients at home,in order to provide evidence for community and home nursing. Methods We searched databases including The Cochrane Library,PubMed,EMbase,ISI Web of Science,PsycINFO,CINAHL,CBM, CNKI,VIP and Wanfang from inception to April 2017,to collect qualitative studies in the experience of family members caring for schizophrenia patients at home. The quality of included studies was evaluated according to JBI Critical Appraisal Tool for qualitative studies in Australia. Results A total of 31 studies were included,and 141 complete findings were grouped according to their similarities to form 8 categories. These categories resulted in two synthesized findings:Integration Results 1:It brought family members a negative influence in care process because of excessive pressure and burden,but over time,they were slowly accepting the fact and trying to cope with dis-ease;Integration Results 2:Patients were unable to take care of themselves,and caregivers were helpless and wanted assistance from the government and the health care system. Conclusion The government and health system should pay more attention to the impact of schizophrenia on family members who take care of schizophrenia patients. In the process of care,patients should be given support,guidance and encouragement,which help family members to improve coping abilities of psychology and disease,and to promote physical and mental health of schizophrenia pa-tients and their family members.

AIM:To evaluate specific metabolomics profiles in the serum of patients with chronic mountain sickness (CMS) and to explore the potential metabolic biomarkers in the native Tibetans living on the Qinghai-Tibet Plateau.METHODS:A gas chromatography time-of-flight mass spectrometry (GC-TOF-MS) approach as a metabolomics technique was used to evaluate metabolic differences.The native Tibetan CMS patients (n =10) and healthy Tibetan controls (n =10) were enrolled from YuShu in Qinghai province in this study.The serum samples were collected and analyzed by GC-TOF-MS coupled with a series of multivariate statistical analyses such as principal component analysis (PCA),partial least squares discriminant analysis (PLS-DA) and orthogonal partial least squares discriminant analysis (OPLS-DA).RESULTS:The intergroup differences between CMS patients and control subjects have been observed.A list of differential metabolites and several top altered rnetabolic pathways have been identified.The levels of fumaric acid,an intermediate in the tricarboxylic acid (TCA) cycle,and inosine were highly upregulated in the CMS patients,suggesting a greater effort to hypoxic adaptation in high elevation area.Other differential metabolites,such as methyl phosphate,2-ketoadipate,lyxose and phytanic acid were also identified.Importantly,the differential metabolites possessed higher area under the ROC curve (AUC) values,indicating an excellent clinical ability for the prediction of CMS.Increased levels of amino acids (isoleucine,glycine,serine,L-cysteine,citrulline and trimethyllysine) were detected in CMS group,yet significantly decreased levels of sulfuric acid,oxamic acid,lyxose and glutamine were also detected in CMS group than those in control group.At the same time,the levels of ribose and glucose-1-phosphate were markedly elevated in CMS group (P ＜ 0.05).CONCLUSION:The metabolic activities are significantly altered in the serum of CMS patients.High altitude hypoxia may act on the disturbed glucose metabolism and amino acid metabolism in part of the Tibetan triggered by CMS.
