Osteoarthritis (OA) is the main reason of joint pain and dysfunction in the elderly in China, and its incidence is increasing year by year. In addition to the joint peripheral osteophyte formation and degeneration of articular cartilage, in?flammation, as one of the dominant pathological changes in OA, is causing more and more attention. Pro-inflammatory cyto?kines (PIC) are important mediators of inflammation. The increased level of PIC in OA can lead to systemic and local inflam?mation, results in further destruction of many kinds of tissues in joint (such as cartilage), and accelerates the development of OA. Besides, the severity of inflammation is closely related to the clinical symptoms of OA. Therefore, it is important to un?derstand the role of PIC in the pathogenesis of OA. From the perspective of the relationship between pro-inflammatory fac?tors and OA and the molecular mechanism, this article reviews the research progress in this field, which provides new con?cepts for diagnose and treatment of OA.

To analyze the composition regularity of Carthami Flos-containing prescriptions of the Drug Standards of Ministry of Health of People's Republic of China-Traditional Chinese Medicine Preparations (the ministerial standards for Traditional Chinese Medicine) based on the traditional Chinese medicine inheritance support system (TCMISS, RZDZ No. 0389952). Efforts were made to identify 331 prescriptions containing Carthami Flos and summarize 16 attending functions and 10 commonly used drug combinations. Three commonly used drug combinations were selected for an in-depth analysis on Carthami Flos's combined administration regularity. Based on Carthami Flos's attending functions, its effects in paralysis, traumatic injuries and dysmenorrheal were compared to analyze Carthami Flos's core drug combinations for treating different diseases. The regularity of clinical administration and the characteristics of commonly used drug combinations were summarized to provide reference for Carthami Flos's clinical application and new ideas for new drug R&D. Carthami Flos prescriptions was mainly used to treat blood stasis and pain and mostly combined with drugs that could activate blood, promote the circulation of qi and dispel pathogenic wind to treat Qi-stagnation and blood stasis caused by various pathogenic factors such as wind, cold and dampness.

Human bocavirus (HBoV) 1-4 have been detected both in respiratory and stool samples since the first HBoV was discovered in 2005. HBoV-1 is mostly associated with respiratory infection, while HBoV 2-4 are usually associated with intestinal tract infection. A variety of signs and symptoms have been described in patients with HBoV infection, including cough, wheezing, pneumonia, and diarrhea, but the research on pathogenic mechanism of HBoV is limited because HBoV cannot be cultured in vitro due to the lack of appropriate host cells. Three-dimensional epithelial cell culture, reverse genetics, and viral metagenomics are identified as novel tools that may promote the research on pathogenic mechanism of HBoV and the discovery of new viruses. This review summaries currently available diagnostic approaches such as electron microscopy, cell culture, PCR, and immunoassay in order to provide a method reference for indepth research on HBoV.

The study aims to develop a unified method to determine seven phenolic acids (neochlorogenic acid, chlorogenic acid, 4-caffeoylquinic acid, caffeic acid, isochlorogenic acid B, isochlorogenic acid A and isochlorogenic acid C) contained in honeysuckle flower that is the monarch drug of all the eight Yinqiao Jiedu serial preparations using quantitative analysis of multi-components by single-marker (QAMS). Firstly, chlorogenic acid was used as a reference to get the average relative correction factors (RCFs) of the other phenolic acids in ratios to the reference; columns and instruments from different companies were used to validate the durability of the achieved RCFs in different levels of standard solutions; and honeysuckle flower extract was used as the reference substance to fix the positions of chromatographic peaks. Secondly, the contents of seven phenolic acids in eight different Yinqiao Jiedu serial preparations samples were calculated based on the RCFs durability. Finally, the quantitative results were compared between QAMS and the external standard (ES) method. The results have showed that the durability of the achieved RCFs is good (RSD during 0.80% - 2.56%), and there are no differences between the quantitative results of QAMS and ES (the relative average deviation < 0.93%). So it can be successfully used to the quantitative control of honeysuckle flower principally prescribed in Yinqiao Jiedu serial preparations.

Objective To investigate the value of contrast-enhanced ultrasonography (CEUS) in the diagnosis of tuberculous mesenteric lymphadenitis by analyzing its enhancement pattern. Methods The conventional ultrasound and contrast-enhanced ultrasound images of 62 patients with tuberculous mesenteric lymphadenitis confirmed by needle core biopsy or surgery were retrospectively analyzed. The location, size, shape, internal echo and posterior enhancement of mesenteric lymph nodes were recorded. All cases were divided into two groups:the maximum diameter of the lymph node≤20 mm and the maximum diameter of the lymph node >20 mm, and the patterns of enhancement in two groups were analyzed. Results The conventional ultrasound of 62 cases with tuberculous mesenteric lymph nodes showed enlargement. And the echogenicity was hypoechoic or heterogeneity, containing punctate or clusters of calcification in 19 cases (30.6%). After CEUS, there were three forms of enhancements:rim enhancement in 29 cases (46.8%);inhomogeneous enhancement in 21cases (33.9%);non-enhancement in 12 cases (19.3%). Rim enhancement was more common in the≤20 mm group, while inhomogeneous enhancement was more common in the lymph nodes>20 mm. There was statistically significant difference of the enhancement type between the≤20 mm group and the>20 mm group (χ2=6.782, P=0.034). Conclusions Most of tuberculous mesenteric lymph nodes showed rim and inhomogeneous enhancement in CEUS, and the sizes of mesenteric lymph node tuberculosis influenced the CEUS enhancement patterns. CEUS may provide useful information for the diagnosis of the tuberculous mesenteric lymph node.
