OBJECTIVE To investigate the effects of parthenolide （PLT） on systemic inflammation and intestinal injury in rats with acute pancreatitis （AP） by regulating the Kelch-like epichlorohydrin-associated protein 1 （Keap1）/nuclear factor-erythroid-2 related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） signaling pathway. METHODS AP rat model was established by injecting 3.5% sodium taurine cholate solution （1 mL/kg） into the biliary pancreatic duct， and modeled rats were divided into AP group， PLT （300 µg/kg） group， dexamethasone （2 mg/kg） group， inhibitor （11 mg/kg Nrf2 inhibitor ML385） group， and PLT+inhibitor group （300 µg/kg PLT+11 mg/kg ML385）， with 10 rats in each group. Another 10 rats were taken as a sham operation group. Each group was given relevant medicine or normal saline via tail vein/intraperitoneal injection once. After 24 h， serum lipase and amylase levels， the levels of oxidative stress index [superoxide dismutase （SOD） and malondialdehyde （MDA）] and inflammatory factors [interleukin-1β （IL-1β）， IL-6 and tumor necrosis factor-α （TNF-α）] were detected. The histopathological changes in colon mucosa and pancreas were observed， and Chiu and Schmidt scores were performed. The cell apoptosis in colon mucosa and the protein expressions of Keap1， Nrf2 and HO-1 were detected. RESULTS Compared with the sham operation group， there was obvious inflammatory cell infiltration in colon mucosa and pancreatic tissue， cell shedding or tissue necrosis and severe bleeding； serum levels of lipase， amylase， MDA， IL-1β， IL-6 and TNF-α， Chiu and Schmidt scores， apoptotic rate and protein expression of Keap1 in colonic mucosa were significantly increased or up-regulated， while SOD level and protein expressions of Nrf2 20230993） and HO-1 were decreased or down-regulated significantly （P＜0.05）. Compared with the AP group， the above indexes in the PLT group and dexamethasone group were significantly improved， while those in the inhibitor group further deteriorated （P＜0.05）. Inhibitor could significantly reverse the improvement effect of PLT on the above indexes in AP rats （P＜ 0.05）. CONCLUSIONS PLT inhibits inflammation and oxidative stress in AP rats， alleviates intestinal damage， and its mechanism may be related to inhibiting protein expression of Keap1 and activating Nrf2/HO-1 signaling pathway.

Allogeneic hematopoietic stem cell transplantation is an effective method for treating various hematological diseases. Membranous nephropathy is the second leading cause of novo glomerular disease after transplantation. Protocadherin FAT1 is a target antigen for diagnosing membranous nephropathy, primarily related to hematopoietic stem cell transplantation. Here we report a rare case of membranous nephropathy after hematopoietic stem cell transplantation. The target antigen of membranous nephropathy was confirmed to be FAT1 by pathology combined with mass spectrometry analysis. The nephrotic syndrome achieved partial remission after corticosteroid combined with cyclosporine treatment, and the patient's condition was stable during follow-up.

OBJECTIVE To quantitatively evaluate the “dual channel” management policy of national medical insurance negotiation drugs at the provincial level， analyze the shortcomings and excellent experience and provide reference for the optimization of the policy. METHODS Taking the “double-channel” management policy of national medical insurance negotiation drugs in 31 provinces as the research object， text mining method was used to summarize the key contents of the policy； the policy modeling consistency （PMC） index model is constructed， and the “dual channel” management policies of 31 provinces are quantitatively analyzed through the evaluation model. Taking Beijing and Chongqing as examples， the differences between good policies and acceptable policies are compared. RESULTS Among the 31 provinces， the PMC index of 18 provinces is between 6.00 and ＜8.00， which belongs to the excellent policies. The PMC index of 13 provinces is between 4.00 and ＜6.00， which belongs to acceptable policies. The policies of Beijing and Chongqing are consistent in 5 aspects， such as policy nature and policy effectiveness， while there are differences in 4 aspects， such as policy content and policy audience. CONCLUSION The “dual channel” management policies in most provinces are at a relatively perfect level， and some provinces need to continuously optimize the policy design and improve the policy rules according to the actual situation of their own medical and health development； establish the management mode of designated pharmacies， clarify the selection rules and exit mechanism； pay attention to the construction of pharmaceutical care， and promote the outflow of prescriptions.

OBJECTIVE To explore the mechanism of Baihe Dihuang decoction in the treatment of Alzheimer's disease(AD) based on network pharmacology, molecular docking and animal experiment. METHODS TCMSP were used to predict the active components and targets of Baihe Dihuang decoction and disease-related targets were collected from GeneCards, OMIM and DRUGBANK databases, respectively. Target protein interactions were analyzed with STRING database and biological function and pathway were analyzed with Metascape database. Lastly relevant results were analyzed with Cytoscape 3.8.0. AutoDock vina software was used for molecular docking to analyze the binding energy of the active components and key targets of Baihe Dihuang decoction. PyMOL software were used to visualize the optimal docking results. ICR male mice were randomly divided into control group, model group, Rolipram group, low, medium and high dose group of Baihe Dihuang decoction. After 14 days of administration, the neurobehavioral scores of mice in each group were collected, and the expression of related proteins in brain tissue was detected, ELISA and Western blotting were used to detect the expression of the key protein cAMP, PKA, p-CREB and BDNF. At last, the adverse reaction of Baihe Dihuang decoction was observed by vomiting experiment. RESULTS A total of 13 active components and 39 key targets were collected from network pharmacology. The docking results showed that the first 10 core targets all performed well and their effects were closely related to PRKACA. Compared with the control group, the model group mice's recognition rate of new objects and the spontaneous alternation reaction rate were significantly reduced, the escape latency was significantly prolonged, and the target quadrant stay time, the number of crossing platforms were significantly reduced; cAMP, PKA, p-CREB and BDNF in the hippocampus of mice was significantly decreased. Baihe Dihuang decoction could reverse the behavior of AD mice and the expression of cAMP, PKA, p-CREB and BDNF. In the vomiting experiment, the anesthesia recovery time of the Rolipram group was significantly prolonged, while that of the Baihe Dihuang decoction group was not significantly affected. CONCLUSION The mechanism of Baihe Dihuang decoction in the treatment of AD may be related to its influence on cAMP-PKA and regulation of cAMP-PKA-CREB-BDNF signal pathway, and the adverse reactions are milder than those of clopramide.

Objective:To evaluate the economy of recombinant human thrombopoietin(rhTPO)combined with conventional therapy compared with conventional therapy in the treatment of sepsis-associated thrombocytopenia(SIT)from the perspective of China's health service system.Methods:The decision tree model was constructed,and the minimum cost analysis and cost-effectiveness analysis were used to evaluate the economy based on the characteristics of sepsis.The economy was judged by two willingness to pay thresholds,and then the stability of the results was tested by sensitivity analysis.Results:rhTPO combined with conventional therapy can save 520.58 yuan for each 1％increase in survival rate compared with conventional therapy alone,which is an absolute advantage program.The single factor sensitivity analysis showed that the daily cost of ICU medical service and the duration of CRRT in the control group and the daily cost of ICU medical service in the experimental group had a great influence on the results,and the stability of the parameter outcome was good.The probability sensitivity analysis showed that when the willingness to pay threshold changes ranged 0～268 074 yuan,rhTPO has a 100％economical probability.Conclusion:Under the existing evidence,rhTPO combined with conventional treatment for SIT treatment is more economical on the basis of improving survival rate and equal safety.
