As a common medical condition， vertigo can be induced by multiple diseases in the modern medical system. Its incidence rate shows an upward trend with the increase in age. According to the theory of mutual interference between clear Qi and turbid Qi in Huangdi's Internal Classic （Huang Di Nei Jing）， this paper systematically analyzes the pathogenesis of vertigo and explores the mechanism and clinical application value of Xiao Chaihutang in the treatment of vertigo. It is believed that the mutual inference between clear Qi and turbid Qi leads to the failure of clear Yang to ascend， resulting in the lack of nourishment for the brain and the inability of turbid Yin to descend， which disturbs the clear orifices， thus causing vertigo. The core pathogenesis lies in the dysfunction of Qi movement， the disorder of body fluid distribution， and the imbalance between Yin and Yang. The compatibility of Xiao Chaihutang takes into account the methods of pungent medicinal materials opening and bitter medicinal materials descending， tonifying deficiency and purging excess， and regulating Qi movement. This prescription can regulate the pathological state of the mutual interference between clear Qi and turbid Qi from three aspects： regulating Qi movement throughout the body， harmonizing the distribution of body fluids， and coordinating Yin and Yang as well as the interior and exterior， thus preventing and treating vertigo. Modern research findings show that Xiao Chaihutang can improve hemodynamics to promote cerebral blood circulation and has anti-inflammation， immunomodulatory， and anti-tumor functions， which correspond to the therapeutic effects of Xiao Chaihutang under the theory of mutual interference between clear Qi and turbid Qi. The decoction exerts therapeutic effects on vertigo caused by hypertension， stroke， otitis media， Meniere’s disease， and brain tumor as well as benign paroxysmal positional vertigo. Further exploration of the theoretical connotation of mutual inference between clear Qi and turbid Qi and analysis of the pathogenesis of vertigo and the therapeutic effect of Xiao Chaihutang can better interpret the internal correlations among the three， thus providing new ideas for the syndrome differentiation and treatment of vertigo.

Objective:To investigate the distribution, drug resistance and clinical significance of bacteria and fungi in pancreatic juice of patients with severe acute pancreatitis (SAP).Methods:Data of patients with severe acute pancreatitis receiving ERCP treatment and pancreatic juice bacterial culture at Department of Hepatobiliary Surgery, General Hospital of Ningxia Medical University from Jan 2019 to Jun 2020 were retrospectively analyzed.Results:A total of 97 patients were included. Pathogens were isolated from 46 (47.42%) pancreatic juice samples, with 71 strains including 43 (60.56%) gram negative bacteria, 26 (36.62%) gram positive bacteria, and 2 (2.82%) fungi. The C-reactive protein (CRP), D-dimer and Balthazar CT Score in the culture positive group were higher than those in the culture negative group ( P < 0.05). The incidence of complications and pancreatic infection in the culture positive group was also significantly higher ( P < 0.05). Conclusions:The positive rate of pancreatic juice bacterial culture in the early stage of severe acute pancreatitis is high, in which Gram-negative bacteria are most common, followed by Gram-positive bacteria and fungi. The presence of pathogens in pancreatic juice predicts ensuing infections.

[Objective]In this paper, valuable experience would be shared and the culture of Chinese medicine will be inherited through introducing the clinical experience of Professor LU Qibin in the diagnosis and treatment of RSA. [Methods]From the point of cause and pathology as well as therapeutic method of the disease, the author discussed the special treatment of Professor LU Qibin. At the same time, the author focuses on introducing the dialectics and characteristics of professor LU Qibin's treatment of complicated recurrent spontaneous abortion. In order to elaborate clearly, some clinical cases were reported. [Results]Professor LU Qibin has summarized that spleen-kidney deficiency is the foundation of recurrent spontaneous abortion. In consequence, invigorating the spleen and kidney is the basic treatment. For the complicated recurrent spontaneous abortion, Professor LU Qibin has many assistant methods on the basis of invigorating spleen and kidney. Such as clearing heat and activating blood, warming and invigorating the spleen and kidney and so on. Furthermore, Professor LU Qibin insists the treatment of traditional Chinese medicine coordinate with western medical therapies. In the reported cases, patients were successfully cured. [Conclusion]Professor LU Qibin is experienced and the clinical curative effect is remarkable. Hence, the clinical experience of Professor LU Qibin in the diagnosis and treatment of recurrent spontaneous abortion was worth of learning and wide application.
