LI Chuang-Peng's Experience in Treating Fever of Unknown Origin from the Perspective of Warming Shaoyinand Unblocking Yangming / 广州中医药大学学报

Fever of unknown origin(FUO)is a difficulty in clinical diagnosis and treatment.Patients with FUO come to seek medical consultation usually with fever as the main complaint,and the accompanying symptoms and signs are generally atypical.The pathogenesis of FUO remains conflicting in the field of modern western medicine,and its treatment is still focused on empirical anti-inflammatory management,which has the deficiency of delayed diagnosis,limited therapeutic options,poor therapeutic effects,and obvious adverse reactions.In the field of traditional Chinese medicine(TCM),FUO generally results from the dysfunction of zang-fu organs and the imbalance of yin and yang,and has the clinical features of long duration of illness,unknown etiology,complexity of illness,recurrent attacks,and difficult to be cured.Based on the six-meridian syndrome differentiation,Chief Physician LI Chuang-Peng pointed out that the pathogenesis of FUO is characterized by the combined disease of shaoyin and yangming,and put forward the therapeutic principle of warming shaoyin and unblocking yangming.He proposed the use of Dahuang Fuzi Decoction(mainly composed of Rhei Radix et Rhizoma and Aconiti Lateralis Radix Praeparata)plus Yiyi Fuzi Baijiang Powder(mainly composed of Coicis Semen,Aconiti Lateralis Radix Praeparata and Patriniae Herba)to subside fever and eliminate pathogen,together with Asari Radix et Rhizoma for guiding the medicine directly to the shaoyin.Moreover,therapies of strengthening and activating spleen and stomach,nourishing yin to produce fluid,and unblocking the blood vessels can be used for eliminating the pathogen and supporting the healthy qi.

Effects of serum containing Dahuang Fuzi Decoction on JAK2/STAT3 signal pathway in mice with severe acute pancreatitis / 中草药

Objective: To study the effects of serum containing Dahuang Fuzi (Rhubarb and Aconite) Decoction (DFD) on JAK2/STAT3 signal pathway in mice with severe acute pancreatitis (SAP). Methods: SAP model in mice was constructed, and then the peritoneal macrophages were vaccinated into the culture plate to set model group, serum containing DFD groups (2.5%, 5%, and 10%), AG490 (10 μmol/L ) positive group, and peritoneal macrophages of normal mice acted as normal control group. After an incubation of 2 h, cells were added with serum containing DFD at different concentration or AG490 0.5 mL, 24 h later, the concentration of TNF-α and IL-6 in supernatant were determined by quantitative sandwich enzyme-linked immunosorbent assay (ELISA) kits, mRNA and protein expression levels of JAK2 and STAT3 in cells were evaluated by Western blotting. Results: DFD could significantly decrease the levels of cytokines TNF-α and IL-6 in the supernatants, inhibit the mRNA and protein expression levels of JAK2 and STAT3 in peritoneal macrophages of SAP mice. Conclusion: DFD could inhibit the JAK2/STAT3 signal pathway and inflammatory responses in peritoneal macrophages of SAP mice.

Preliminary study on serum pharmacochemistry of Dahuang Fuzi Decoction / 中草药

Objective: To carry out a preliminary study on serum parmacochemistry of Dahuang Fuzi Decoction (DFD) and to research the pharmacodynamic material basis through analyzing the constituents absorbed into blood. Methods: HPLC fingerprints of DFD and serum of rats after DFD treatment were established with serum pharmacochemistry method. The serum samples collected after DFD and single crude drug treatments were compared, the constituents absorbed into the serum after DFD ig administration was determined. Results: After the rats were ig administered with DFD, 18 transitional constituents to blood were detected, among which 14 were metabolites and 4 were prototype constituents. Conclusion: After DFD treatment, the constituents absorbed into blood are mainly from Rhei Radix et Rhizoma and Aconiti Lateralis Radix Praeparata, and the serum pharmacochemistry signs could provide the evidence for the further research of the material basis of the decoction.

Effect of Dahuang Fuzi decoction on alveolaur epithelial barrier in rats with lung injury with severe acute pancreatitis / 中华急诊医学杂志

Objective To investigate effect of Dahuang Fuzi decoction on alveolaur epithelial barrier in rats with lung injury with severe acute pancreatitis. Method Ninty-six health SD rats were randomly divided into three groups: sham operation group, SAP-ALI group, Dahuang Fuzi decoction group, and then according to the time point of sacrifice after operation, each group was subdivided into 3,6,12,24 hour subsets ( each, n = 8). After the belly of a rat in the sham operation group was cut open, the pancreas was flipped several times,and then a stoma was made in the jejunum to form its fistula. In the SAP-ALl group,1 mL/kg sodium taurocholate was reversely injected into the pancreatobile duct to establish the model of SAP, and then the jejimum fistula was performed. The SAP-ALI model in Dahuang Fuzi decoction group was treated by injection of 10ml of Dahuang Fuzi decoctionon into the fistula respectively. Blood was collected from heart to detect serum amvlase and endotoxin (ET) levels before the rat being executed. The lung histopathologic changes, pulmonary injury scores and wet/dry weight(W/D) ratios were observed after the rats were executed. The alveolar liquid clearance rate(ALCR), total lung water content (TLW), extravascular lung water content(EVLW) and alveolar epithelial permeability (AEP) were examined in 3,6, 12,24 h after injury.Results There was continuous increase of AEP,TLW and EVLW,as well as progressive reduction of ALCR compared with sham operation group at 3,6,12,24 h after operation. Compared with SAP-ALI group, there was continuous decrease of AEP,TLW and EVLW, and elevated of ALCR at 3,6,12,24 h after operation.Conclusions Dahuang Fuzi decoction can significantly reduce alveolaur epithelial barrier and degree of lung tissue of SAP-ALI rats by inhibiting the elevation of LPS and inflammation reaction.
