Crohn's disease(CD) is a lifelong disease and the precise aetiology is still unknown.Differences in the definitions and diagnosis between clinicians make direct influence on therapeutic efficacy on CD.This article overviewed the progresses on the definitions such as staging,relapse,and diagnosis of Crohn's disease in these years in order to decrease the mistakes and be helpful to institute sensible and effective therapeutic regimen.

There were a lot of general researches and applications about constitution in Shanghan-Zongbing Lun ofPang Anshi. It is found that the constitution idea ofPang Anshi originated from Huangdi-Neijing. His constitution idea included that: the constitution formation was related to living environment and diet; the constitution factors should be considered in the clinical practice; the constitution factors should be considered when applicating Yang-preserving in spring and summer, Yin-preserving in autumn and winter; the constitution factors should be considered in the process of the choice of dosage, the method of decoction and the principle of medication. Pang Anshi constitution idea is of great important guidance for the later medical practice.

Calcium-sensing receptor(CaSR)is expressed in human parathyroid cells and renal tubular epithelial cells mainly.CaSR could control parathyroid hormone(PTH)secretion and the renal tubular's handing of the electrolytes and water.This receptor plays a central role in extracellular calcium homeostasis,and involves in the process of bone remodeling.The change of CaSR function,including anti-CaSR antibodies,CasR gene mutations or any part impairment in CaSR signaling pathway,not only results in the imbalaance of PTH and calcium homeostasis.but also relates to disorders of bone remodeling and renal tubular's mishandling in the electrolytes and water,which contribute to hyperparathyroidism.It makes possible clinical Use of cinacalcet in hyperparathyroidism in theory.

Objective To study the outcome of distal third clavicular fracture treated with AO clavicular hook plate. Methods From May 2001 to May 2003, 14 cases of fresh distal third clavicular fracture (Neer typeⅡ) were treated with AO clavicular hook plate in our hospital. Results All the cases obtained satisfactory results. No infection, nonunion, ineffective internal fixation, or loosening or breakage of the plate occurred. Conclusion The treatment of distal third clavicular fracture with AO clavicular hook plate is an effective surgical method.

Osteoporosis, which is characterized by reduced bone mineral density (BMD) and an increased risk of fragility fractures, is the result of a complex interaction between environmental factors and genetic variants that confer susceptibility. Fracture and other complications caused by osteoporosis have serious impact on the life quality and life span of patients. Although previous linkage and candidate gene studies have provided few replicated loci for osteoporosis, genome-wide approaches and next generation sequencing have produced clear and reproducible findings. To date, 25 genome-wide studies for osteoporosis and related traits have been conducted, identifying 76 genes and loci. In this review, we will update the genetic study of osteoporosis and provide some perspective views.

TNF-?,a pleiotropic cytokine with strong proinflammatory and immunomodulatory properties is known to play an important role in inflammatory bowel disease(IBD).The biological effects of TNF-? are elicited by binding to its two cognate recepters,TNFR1 and TNFR2.For a long time,TNF-R1 was considered to be the predominant mediator of TNF-signaling,whereas TNF-R2 was ascribed only auxilliary function.However,there is increasing clinical and experimental evidence for an important independent role of TNF-?/TNFR2 signaling in chronic inflammatory conditions of IBD.The elucidation of the different effects of TNF-signaling in IBD will lead to a better understanding ot the pathogenesis of these diseases and will be the basis for the development of more specific and more efficient therapeutic approaches.

The blood pressure changes is very common in patients with acute ischaemic stroke.However,the optimal management of the blood pressure in acute ischaemic stroke remains unclear.There is a very important clinical significance on how to manage hypertension in acute ischaemic stroke.The review summarizes recent guidelines on blood pressure management after acute ischaemic stroke.The aim of the review is to expound the treated principle of hypertension in acute ischaemic stroke.

0.990 0) with an average recovery ranged from 86.1% to 109.0%.The injection RSD were within 0.84%～3.1%(n=6).CONCLUSIONS:The method is successfully applied for simultaneous determination of 22 kinds of free amino acids.

Objective To explore the nursing strategies for preoperative ventilator-dependent patients undergoing discontinuing mechanical ventilation after lung transplantation.Methods The clinical data and nursing experiences of 10 preoperative ventilator-dependent patients undergoing discontinuing mechanical ventilation after lung transplantation from September 2002 to December 2008 were retrospectively analyzed.Results The time of discontinuing mechanical ventilation ranged from 7 to 30 days and the average time was 16.5 days.Conclusion The key points to ensure the success of discontinuing mechanical ventilation were careful observation of ventilation modes,preparations before discontinuing,airway management,nutritional support and psychological nursing.

Background The commonly used method of typing the adenovirus (AdV) for epidemic keratoconjunctivitis is direct DNA sequence.However,heteroduplex mobility assay (HMA) is found to be a faster method to identify the subtypes of adenovirus and is more conforming to the principle of cost and economic benefit.There are few studies to illustrate the application of HMA in epidemic keratoconjunctivitis.Objective This study analyzed the conserved region of hexon coding sequence and compared the outcomes between direct DNA sequence and HMA for classification of adenovirus in epidemic keratoconjunctivitis patients.The validity of HMA is evaluated by comparing the result of both studies Methods Two hundreds and fourteen patients with suspicious epidemic keratoconjunctivitis were included in Shanghai Eye Disease Prevention and Treatment Center or the clinical sites supervised by the Shanghai Prevention and Monitoring Office of Acute Hemerragic Conjunctivitis from January 2010 to December 2012.Sacconjunctival swab samples were collected from each patient under the informed consent.DNA of pathogens was extracted from the samples using QIA-amp minikit,and the conserved sequence with 366 bp at hexon protein coding region was amplified by PCR and sequenced subsequently to determine the infected adenovirus and their subtypes.These samples were simultaneously assayed by HMA,and the outcomes between DNA sequence and HMA were compared.Results Extracted DNA presented a yellow fluorescence band with the fragment size 35 kb and absorbance ratio at the wavelength 260 nm and 280 nm (A260/A280) was I.7.In the 214 samples,AdV type 1 (AdV1) was found in 4 samples,AdV2 in 33 samples,AdV3 in 15 samples,AdV4 in 12 samples,AdV8 in 19 samples,AdV19 in 15 samples and AdV37 in 8 samples.HMA showed the same outcome for the identification of AdV1,AdV2,AdV3,AdV8,AdV19 and AdV37 with direct DNA sequence.AdV4 was not feasible to HMA owing to 59.6％ (over 10％) mutation sites.Conclusions Direct DNA sequencing for conserved regions in coding sequence of hexon is an important way to identify causing-disease adenovirus subtypes in the patients with epidemic keratoconjunctivitis.HMA can offer a consistent result with the DNA sequencing,and it might be used as a suitable tool for large-scale molecular epidemiology researches.
