RESUMEN
Brucellosis is a zoonotic infectious disease caused by Brucella infection. So far, animal to animal Brucellosis has not been eradicated, and there is a lack of safe and effective human vaccine. Therefore, "early, combined, sufficient, and full course" drug treatment remains an important strategy in the management of human Brucellosis. The goal of treating brucellosis is to alleviate and shorten the symptom period, reduce complications, relapses, and chronicity. At present, although antibiotic treatment is effective for most patients, there are still some patients who experience treatment failure or later recurrence, so the treatment strategy for brucellosis urgently needs to be optimized. This article elaborates on the treatment principles, clinical treatment status, and future development trends of brucellosis, in order to provide references for optimizing drug treatment methods for brucellosis.
RESUMEN
BACKGROUND@#Clinical trial evidence is limited to identify better topical non-steroidal anti-inflammatory drugs (NSAIDs) for treating knee osteoarthritis (OA). We aimed to compare the clinical efficacy and safety of flurbiprofen cataplasms (FPC) with loxoprofen sodium cataplasms (LSC) in treating patients with knee OA.@*METHODS@#This is an open-label, non-inferiority randomized controlled trial conducted at Peking University Shougang Hospital. Overall, 250 patients with knee OA admitted from October 2021 to April 2022 were randomly assigned to FPC and LSC treatment groups in a 1:1 ratio. Both medications were administered to patients for 28 days. The primary outcome was the change of pain measured by visual analog scale (VAS) score from baseline to day 28 (range, 0-10 points; higher score indicates worse pain; non-inferiority margin: 1 point; superiority margin: 0 point). There were four secondary outcomes, including the extent of pain relief, the change trends of VAS scores, joint function scores measured by the Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and adverse events.@*RESULTS@#Among 250 randomized patients (One patient without complete baseline record in the flurbiprofen cataplasms was excluded; age, 62.8 ± 10.5 years; 61.4% [153/249] women), 234 (93.6%) finally completed the trial. In the intention-to-treat analysis, the decline of the VAS score for the 24-h most intense pain in the FPC group was non-inferior, and also superior to that in the LSC group (differences and 95% confidence interval, 0.414 (0.147-0.681); P <0.001 for non-inferiority; P = 0.001 for superiority). Similar results were observed of the VAS scores for the current pain and pain during exercise. WOMAC scores were also lower in the FPC group at week 4 (12.50 [8.00-22.50] vs . 16.00 [11.00-27.00], P = 0.010), mainly driven by the dimension of daily activity difficulty. In addition, the FPC group experienced a significantly lower incidence of adverse events (5.6% [7/124] vs . 33.6% [42/125], P <0.001), including irritation, rash and pain of the skin, and sticky hair uncovering pain.@*CONCLUSIONS@#This study suggested that FPC is superior to LSC for treating patients with knee OA in pain relief, joint function improvement, and safety profile.

OBJECTIVE:To explore the effects of the different compatibility ratios of rutin with quercetin on the pharmacoki-netics of rutin in rats in vivo. METHODS:30 rats were randomly divided into rutin group(rutin-quercetin molar ratio of 4:0,the same below),quercetin group(rutin-quercetin ratio of 0:4),BL1 group(rutin-quercetin ratio of 3:1),BL2 group(rutin-quercetin ratio of 2:2)and BL3 group(rutin-quercetin ratio of 1:3),6 rats in each group,all group was administrated 10 mg/kg(calculat-ed by quercetin core of rutin and quercetin) intragastrically. The blood sample 0.3 mL was respectively taken from tail vein after 0.25,0.5,0.75,1,1.5,2,3,4,6,8,10,12,16,20,24 h of administration,the plasma concentration of quercetin(rutin me-tabolite) was determined by HPLC. DAS 2.0 software was used to calculate the pharmacokinetic parameters. RESULTS:The AUC0-24 h in rutin group,quercetin group,BL1 group,BL2 group and BL3 group were (4.908 ± 0.877),(8.382 ± 3.671), (8.473 ± 0.709),(4.366 ± 2.297),(8.914 ± 2.642)μg·h/L;MRT0-24 h were (9.675 ± 1.359),(3.142 ± 0.489),(3.517 ± 1.128), (3.376 ± 1.046),(4.494 ± 1.653) h;tmax were (5.726 ± 5.645),(1.375 ± 0.703),(1.125 ± 1.438),(1.417 ± 2.300),(1.292 ± 0.954) h;and cmax were (0.609 ± 0.202),(2.341 ± 0.539),(2.425 ± 1.217),(1.464 ± 0.677),(3.325 ± 2.425)μg/L. Compared with rutin group,AUC0-24 h and cmax in quercetin group,BL1 group and BL3 group were significantly increased(P0.05). CONCLUSIONS:Quercetin can inhance the related indexes of rutin in rats in vivo.

Objective To investigate the impact of minimally invasive osteosynthesis (MIPO)combined with locking plate fixation for the prognosis of patients with fractures of the tibia and Pilon.Methods 84 patients with CT or X -ray diagnosis of tibial Pilon fracture were randomly divided into group A (n =42)and group B (n =42). The group A were threatment with MIPO combination locking plate fixation and group B were threatment with reduction and internal fixation.The following -up clinical and radiological data of the two groups were compared. Results The blood loss of group A were less than group B(t =8.963,P <0.05),postoperative pain score were lower than group B(t =10.789,P <0.05),while the satisfaction score was higher than group A (t =8.963,P <0.05), postoperative hospital stay,healing time were shorter than group B (t =9.362,10.556,all P <0.05).The Conroy scoring system and Tenny scoring system of A group of excellent rates were 95.24%,76.19% were higher than 92.86% and 71.43% of group B(χ2 =6.222,6.574,all P <0.05).The overall complication rate of A group was lower than the group B(χ2 =7.265,P <0.05 ).Conclusion MIPO combination of locking plate fixation Pilon fractures can reduce soft tissue dissection,reduce surgical trauma to the patient,reduce postoperative complications in patients,in favor of patients recover as soon as possible.

RESUMEN
The systematic approaches of metabonomics are similar to the essential attribution in concept of the wholism for traditional Chinese medicine (TCM) theories. The metabonomics had been progressively utilized to study the TCM theories, such as "ZHENG" (synelromes), or the systematic mechanism of Chinese materia medica (CMM) and its formulae by animal models, and toxicology in recent years. These studies almost focused on the responeses of endogenous metabonome to biological stimuli or genetic manipulation (pharmacodynamics and toxicology) by TCM theory of "ZHENG", while less involved the precess of formulae itself and its dynamic changes (pharmacokinetics) by TCM theory of "FANG". The "treatment by differentiating syndrome" and "Correspondence of FANG-ZHANG" is the quintessence of TCM theories. Consequently, in this idea, the application of PK-PD methods based on metabonomics and "FANG-ZHENG correspondence" to investigating the compatibility of the formulae in TCM theory is discussed in this paper.
