Oral film is a new type of oral preparation. Due to portability, simple preparation process and good clinical compliance, oral films have become the focus of novel drug delivery system in recent years. Meanwhile, oral films have been gradually used in the development of Chinese medicine preparations. ⋯ Some suggestions on the technical evaluation of oral films were put forward by considering specific requirements from regulatory agencies. This paper could provide some references for the development and evaluation of oral films. Due to the complexity of the drug substances and the particularity of the drug product, the development and application of oral films in traditional Chinese medicine are still faced with opportunity and challenges.

Review[Effect of proinflammatory factors TNF-α,IL-1β, IL-6 on neuropathic pain].
Cytokines can be divided into two types： proinflammatory cytokines and anti-inflammatory cytokines. Proinflammatory cytokines are a kind of small molecular peptides synthesized and excreted by immune and non-immune cells, which can regulate a variety of physiological functions and play an important role in the process of trauma, pain and infection. ⋯ In recent years, with the deepening of studies on neuropathic pain mechanism and the increasing expansion of the neuroinflammation study field, the action mechanisms of cytokines and molecules in regulating cytokines in neuropathic pain are expected to provide new targets for the development of analgesic drugs. This review aims to provide an overview of inflammatory mechanisms for proinflammatory cytokines TNF-α, IL-1β, IL-6, with a focus on neuropathic pain.

Meta Analysis[Efficacy and safety of Kuhuang injection in treating viral hepatitis： systematic review and Meta-analysis of randomized controlled trials].
To systematically evaluate the effectiveness and safety of Kuhuang injection in treating viral hepatitis. Eight electronic databases and clinic trials were searched to collect randomized controlled trials for the effect of Kuhuang injection in the treatment of viral hepatitis. According to the Cochrane Handbook 5.1, two independent reviewers screened out the literatures, extracted data and assessed the quality of thestudies included. ⋯ Most clinic trails did not include viral hepatitis etiology, clinical classification and diversified intervention measures, which resulted in a high clinical heterogeneity and poor comparability between trails. Besides, most trials had a low methodological quality, which affected the authenticity of the results. Therefore, more high-quality, multi-center, large-sample, randomized double-blind controlled trialsarerequired to prove the evidences.

[Prescription regularity of famous veteran traditional Chinese medicine Doctor Yu Guoyou for treating gastrointestinal failure based ondata mining].
Gastrointestinal failure is a kind of severe systemic inflammatory response, and often complicated with multiple organ dysfunction syndrome. Integrated traditional Chinese and Western medicine have a better curative effect in treating it. This study collected the famous veteran TCM physician Yu Guoyou's 175 prescriptions for treating 89 cases of gastrointestinal failure, calculated the frequency of traditional Chinese medicines and their categories, and analyzed the medication regularity with system clustering method, so as to summarize Yu's frequently used drugs and prescriptions. ⋯ In the treatment of gastrointestinal function failure, Yu gives priority to strengthening spleen, regulating Qi and purgation, prescribes medicines for dissolving blood stasis and detoxication, dissipating dampness, clearing heat and eliminating phlegm according to syndrome types. In other words, the treatment is based on syndrome differentiation, and the prescription is modified according to symptoms. In particular, Yu attaches importance to stomach-Qi recuperation and gastrointestinal function recovery in the process of treatment.

[Effects of sampling time on polysaccharides of Dendrobium catenatum under temperature-controlled condition].
In order to reveal the accumulation trend of polysaccharides in Dendrobium catenatum and determine the effect of sampling time on polysaccharides, D. Catenatum D21 clone was harvested from January to December after culturing for 2 to 5 months in the growth chamber with constant temperature. ⋯ The results showed that the content of polysaccharide and its key component mannose was positively correlated with the culture time, but the contents of polysaccharides in all kinds of culture peaked from 5 to 6 months, which were consistent with the trend of field planting. The results suggested that the trend of polysaccharide accumulation in the plant could be related to the life rhythm of the sensory seasons of D. catenatum, which was significantly affected by the harvesting season, even under the constant condition of the culture chamber.
