Objective To compare the effect of conservative and operative treatment for cervical spinal cord injury without fracture and dislocation (CSCIWFD)and to detect mechanism of injury as well as its relationship to outcome.Methods A retrospective review was conducted on 688 patients with CSCIWFD treated from August 1994 to March 2013.There were 155 patients managed conservatively (conservation group) and 533 surgically (operation group).Neurological function improvement was compared between two groups to detect the correlation of patents' age and treatment methods with outcome.Results The patients were followed up for mean 17.9 months (range,3-36 months).Neurological function was estimated using Japanese Orthopedic Association (JOA) score:(1) the recovery rate of patients aged over 40 years in operation group was better than that in conservation group (P ＜0.05) ; (2) the recovery rate in patients aged under 39 years was unsatisfactory in both groups,with insignificant difference between the two groups (P ＞ 0.05).Conclusions Different age of patients with CSCIWFD has different injury mechanism,injury severity and outcome.Surgery provides better results than conservative treatment for patients aged over 40 years,but both results are poor for patients aged under 39 vears.

Objective To estimate the bladder symptoms, and explore its impact on patients′ quality of life in type 2 diabetes mellitus. Methods Overactive bladder symptom score (OABSS) was used to evaluate patients′ bladder symptoms, and Medical Outcome Study 12-Item Short Form Health Survey Scale (SF-12), Overactive Bladder Questionnaire Short Form(OABq-SF)were conducted to test the effect of bladder symptoms on general and disease-specific quality of life. Results Among the four bladder symptoms, nocturia was the most prevalent symptom (46.7%,479/1025 ), followed by urinary frequency (14.9%,153/1025 ),urinary urgency (14.2%,146/1025 ), urge urinary incontinence (7.9%, 81/1025). Nocturia and urge urinary incontinence significantly increased symptom bother (nocturia B=0.337,P<0.01;urge urinary incontinence B=0.437,P<0.01) and decreased disease-specific quality of life (nocturia B=-0.364,P<0.01;urge urinary incontinence B=-0.346, P<0.01) in these patients. Meanwhile, urge urinary incontinence was negatively associated with general mental health (B=-0.255, P=0.011). Conclusions The prevalence of bladder symptoms in type 2 diabetes patients was high, and was found to be associated with patients′general and disease-specific quality of life. Health care providers should be aware of the high prevalence of bladder symptoms and its impact on QOL to facilitate early diagnosis and treatment of bladder symptoms during diabetic care.

Mugwort leaf is the traditional herb being used for moxibustion. Although its place of production and the course of making Mugwort floss have been described in detail, there is no unified standard about the quality and processing of Mugwort floss until now, which seriously affect on the popularity and application of moxibustion. In accordance with the real herb of Mugwort leaf and floss as well as its processing and quality judgment, this paper thoroughly analyze the related data including ancient documents, modern research results and clinical applications. The authors consider that the Mugwort floss in the market is lack of regulations for its processing, and it needs to be discussed the way to judge the quality of Mugwort leaf by volatile oil, suggesting that the further study on the quality control of Mugwort leaf and floss has to be carried out from multiple aspects, such as physical attributes and chemical characteristics.

Smoking is the primary cause of lung cancer and is linked to 85% of lung cancer cases. However, how lung cancer develops in patients with smoking history remains unclear. Systems approaches that combine human protein-protein interaction (PPI) networks and gene expression data are superior to traditional methods. We performed these systems to determine the role that smoking plays in lung cancer development and used the support vector machine (SVM) model to predict PPIs. By defining expression variance (EV), we found 520 dynamic proteins (EV>0.4) using data from the Human Protein Reference Database and Gene Expression Omnibus Database, and built 7 dynamic PPI subnetworks of lung cancer in patients with smoking history. We also determined the primary functions of each subnetwork: signal transduction, apoptosis, and cell migration and adhesion for subnetwork A; cell-sustained angiogenesis for subnetwork B; apoptosis for subnetwork C; and, finally, signal transduction and cell replication and proliferation for subnetworks D-G. The probability distribution of the degree of dynamic protein and static protein differed, clearly showing that the dynamic proteins were not the core proteins which widely connected with their neighbor proteins. There were high correlations among the dynamic proteins, suggesting that the dynamic proteins tend to form specific dynamic modules. We also found that the dynamic proteins were only correlated with the expression of selected proteins but not all neighbor proteins when cancer occurred.

Antibody-drug conjugate (ADC) is a new class of therapeutics composed of a monoclonal antibody and small cytotoxin moieties conjugated through a chemical linker. ADC molecules bind to the target antigens expressed on the tumor cell surfaces guided by the monoclonal antibody component. The binding ADC molecules can be internalized and subsequently the toxin moieties can be released within the tumor cells via chemical and/or enzymatic reactions to kill the target cells. The conjugation combines the merits of both components, i.e., the high target specificity of the monoclonal antibody and the highly potent cell killing activity of the cytotoxin moieties. However, such complexities make the pharmacokinetic and metabolic studies of ADCs highly challenging. The major challenges should include characterization of absorption, distribution, metabolism and excretion, investigation of underlying mechanisms, assessment of pharmacokinetic- pharmacodynamic relationship, and analytical method development of ADC drugs. This review will discuss common pharmacokinetic issues and considerations, as well as tools and strategies that can be utilized to characterize the pharmacokinetic and metabolic properties of ADCs.
