OBJECTIVE To enhance the training quality of anticoagulation specialty clinical pharmacists， address the resource limitations of a single training base， and promote homogenization of training quality. METHODS A multi-base joint training system for anticoagulation specialty clinical pharmacists in the Beijing area was established. A mixed research method was employed， collecting data through performance comparisons， questionnaires， and qualitative interviews to compare the differences between the joint training model （experimental group， n＝16） and traditional teaching model （the control group， n＝17）. RESULTS The established joint training system encompassed a unified joint training teaching plan， the formation of a joint training teaching team， the establishment of joint theoretical teaching courses， the implementation of joint case discussions and literature presentations， as well as strengthening the assessment throughout the joint training process. Compared to the control group [theoretical assessment of （76.44±3.66） points， case assessment of （84.31±3.27） points]， the experimental group students achieved higher scores in theoretical assessment （[ 79.85±4.64） points] and case assessment （[ 88.70±5.51） points] （P＜0.05）. Through questionnaires and qualitative interviews， the trainees in experimental group were highly satisfied with the joint training model in terms of theoretical learning， communication skills， and teaching interaction. CONCLUSIONS The multi-base collaborative training system for anticoagulation specialty clinical pharmacists can integrate advantageous resources and significantly enhance the training effectiveness of anticoagulation specialty clinical pharmacists， offering value for wider promotion.

Exercise intervention is an important non-pharmacological intervention for various diseases, and establishing precise exercise load assessment techniques can improve the quality of exercise intervention and the efficiency of disease prevention and control. Based on data collection from wearable devices, this study conducts nonlinear optimization and empirical verification of the original "Fitness-Fatigue Model". By constructing a time-varying attenuation function and specific coefficients, this study develops an optimized mathematical model that reflects the nonlinear characteristics of training responses. Thirteen participants underwent 12 weeks of moderate-intensity continuous cycling, three times per week. For each training session, external load (actual work done) and internal load (heart rate variability index) data were collected for each individual to conduct a performance comparison between the optimized model and the original model. The results show that the optimized model demonstrates a significantly improved overall goodness of fit and superior predictive ability. In summary, the findings of this study can support dynamic adjustments to participants' training programs and aid in the prevention and control of chronic diseases.

Objective To investigate the effect of lidocaine medicated plaster （LMP） combined with pregabalin （PGB） on patients with postherpetic neuralgia （PHN）, and the impact on serum pain mediators. Methods 108 PHN patients admitted in our hospital from January 2024 to December 2024 were selected and grouped according to the time point of receiving treatment, 54 PHN patients treated with PGB from January 2024 to June 2024 were included in the PGB group, and 54 PHN patients treated with LMP on top of the PGB group from July 2024 to December 2024 were included in the PGB+LMP group. Comparisons were made between the two groups in terms of pain score, serum pain mediator levels, dosage of PGB, and incidence of adverse reactions. Results After 4 weeks of treatment, both groups showed a decrease in Pain Rating Index scores （sensory score and affective score）, Present Pain Intensity score, Visual Analog Scale score, and total score. Meanwhile, above scores of the PGB+LMP group were lower than those of the PGB group （P<0.05）. After 4 weeks of treatment, the levels of substance P（SP） and neuropeptide Y （NPY） in both groups were lower than those before treatment, while serum 5-hydroxytryptamine （5-HT） levels were higher than those before treatment. Moreover, the levels of SP and NPY were lower, and 5-HT level was higher in the PGB+LMP group than in the PGB group （P<0.05）. The dosages of PGB in the PGB+LMP group at T1, T, T3 and T4 were significantly lower than those in the PGB group （P<0.05）. The incidence of adverse reactions was 1.85%（1/54） in the PGB+LMP group. Compared to 5.56%（3/54） in the PGB group, and the difference was not statistically significant （P>0.05）. Conclusion LMP combined with PGB was effective in the treatment of patients with PHN, which could effectively alleviate pain and lower the levels of serum pain mediators, with good safety.

OBJECTIVE To extract the-SH active fractions(SHF)from Bubali Cornu(water buffalo horn)and evaluate its an-tipyretic activity.METHODS SHF was extracted from Bubali Cornu by SDS-DTT,and the content of native thiols(-SH)was deter-mined by Ellman reagent method.SHF was identified based on nano LC-MS/MS technology.Evaluation of antipyretic activity of SHF was based on LPS-induced fever rat model.The levels of PGE2,IL-1β,and TNF-α in plasma as well as the levels of cAMP,PGE2,and TNF-α in the hypothalamus were measured by ELISA kits.An untargeted metabolomics approach was used to further investigate the intervention of SHF on plasma metabolites in febrile rats.RESULTS SDS-DTT could effectively extract SHF from Bubali Cornu,in which the main components were type Ⅰ,type Ⅱ keratins and keratin-associated proteins,which were rich in Cys,and the ratio of-SH to protein in SHF was increased about 20 times more than that of traditional decoction.SHF could significantly decrease(P＜0.01)the body temperature which lasted for 4.5 hours.SHF could also significantly decrease the levels of PGE2,IL-1β,TNF-α and cAMP in plasma and hypothalamic.A total of 137 potentially differential metabolites were identified from plasma samples of the control and model groups,of which 31 metabolites could be dialed back after SHF administration,including lysophosphatidic acid,phosphatidyli-nositol,phosphatidic acid,triglycerides,phosphatidylcholine and so on,which were mainly involved in the glycerophospholipid meta-bolic pathway.CONCLUSION SHF has precise antipyretic effect,and the dosage of 1/10 of the aqueous extract can show its com-parable antipyretic effect,which provides the direction and basis for the basic research on the antipyretic efficacy of Bubali Cornu.

BACKGROUND:In recent years,the development of liver organoids has made it a hot spot in the field of international liver disease research,but there is still no article on the bibliometric analysis of liver organoids. OBJECTIVE:To explore the hot trends in liver organoids in the last 20 years based on bibliometrics and visualization analysis. METHODS:We searched the articles about liver organoids in the Web of Science Core Collection from January 1,2002 to November 12,2022.Origin,Office,and CiteSpace software were used for bibliometrics and visualization analysis.We statistically analyzed the number of annually published articles,countries,institutions,authors,journals,and keywords of the articles by generating charts.

Objective To explore the effect of acute caffeine and theanine supplementation on coordi-nation and aerobic performance in mentally fatigued soccer players.Methods A randomized crossover de-sign was employed with 15 male amateur soccer players.Participants underwent three different interven-tions—caffeine(caffeine group),theanine(theanine group),and placebo(placebo group)—with a one-week washout period between each intervention.After each supplementation,participants performed a 45-minute Stroop task to induce mental fatigue,followed by a speed dribbling test(SDT)and the 30-15 intermittent fitness test(30-15IFT)to assess coordination and aerobic performance,respectively.Mea-surements included visual analog scale for mental fatigue(VAS-MF),motivation(VAS-MO),Brunel mood scale for fatigue(BRUMS-F)and vigor(BRUMS-V)pre-and post-Stroop task,response time(RT),response accuracy(ACC),average heart rate(HRave)during Stroop,mental exertion(VAS-ME)post-Stroop,rating of perceived exertion(RPE),HRave,and peak heart rate(HRpeak)during SDT and 30-15IFT.All data were analyzed using repeated measures ANOVA.Results The change in VAS-MF(ΔVAS-MF)before and after the Stroop task was lower in the caffeine group compared to the placebo group(P=0.064),while the theanine group showed similar ΔVAS-MF to the latter group(P=0.999).Both the caffeine and theanine groups had significantly faster RT(P=0.003 and 0.033,respectively)and higher ACC(P=0.006 and 0.033,respectively)during the Stroop task compared to the placebo group.Moreover,coordination performance in both the caffeine and theanine groups was better than the placebo group(P=0.096 and 0.078,respectively).Meanwhile,aerobic performance in the caffeine group was significantly better than the placebo group[time to exhaustion(TTE):P=0.012;last stage ve-locity of 30-15IFT(VIFT):P=0.007;maximal oxygen uptake(VO2max):P=0.008],whereas no significant differences were found between the theanine group and the placebo group in the aerobic performance(TTE:P=0.999;VIFT:P=0.999;VO2max:P=0.999).Conclusion Both acute caffeine and theanine supple-mentation can mitigate the negative effect of mental fatigue on coordination performance in soccer play-ers.Additionally,acute caffeine supplementation can also alleviate the negative impact of mental fa-tigue on aerobic performance.

Objective:To compare the efficacy of monopolar electric scissors and harmonic scalpel in Da Vinci robot-assisted distal pancreatectomy.Methods:A total of 31 patients undergoing Da Vinci robot-assisted distal pancreatectomy at the Affiliated Hospital of Xuzhou Medical University from July 2020 to December 2023 were included. There were 9 males and 22 females, aged (54.4±15.7) years. Thirty-one patients who underwent Da Vinci robot-assisted distal pancreatectomy by monopolar electric scissors were included in the monopolar electric scissors group ( n=12), with a multi-joint flexible rotating mechanical arm to complete the dissection and separation and the other were inducled in harmonic scalpel group ( n=19). Operation time, intraoperative blood loss, spleen preservation, postoperative exhaust time, postoperative hospital stay, postoperative complications and total hospitalization cost were compared between the two groups. Results:Postoperative pathology confirmed that among the 31 patients, there were 6 cases (19.4%) serous cystadenomas, 5 cases (16.1%) mucinous cystadenomas, 3 cases (9.7%) pancreatic neuroendocrine tumors, 6 cases (19.4%) solid pseudopapilloma, 5 cases (16.1%) pancreatic cysts, and 3 (9.7%) benign cystic lesions, 3 cases (9.7%) were not easily classified. All the operations were successfully completed without conversion to laparotomy or death. There were no significant differences in operation time, intraoperative blood loss, splenic preservation rate, postoperative hospital stay and total hospitalization cost between the two groups (all P>0.05). The exhaust time in the monopolar electric scissors group was (2.8±0.7) d, which was shorter than that in the harmonic scalpel group (3.6±0.7) d, and the difference was statistically significant ( t=-2.88, P=0.007). There was no postoperative bleeding in both groups. In the monopolar electric scissors group, there were 4 cases of postoperative complications, all of which were pancreatic fistula, including 2 cases of biochemical leakage and 2 cases of B-grade pancreatic fistula. In the harmonic scalpel group, 8 cases had postoperative complications, 7 cases of pancreatic fistula, including 3 cases of biochemical leakage, 4 cases of B-grade pancreatic fistula, and 3 cases of abdominal infection, which were cured after treatment. There was no significant difference in the incidence of postoperative complications between the two groups ( P=0.717). Conclusion:The application of monopolar electric scissors in Da Vinci robot-assisted distal pancreatectomy could be safe and feasible in experienced hands, which could also utilize the advantages of robot system.

Objective:To investigate the safety and efficacy of using bio-artificial dura mater to wrap around skeletonized hepatic artery during pancreatoduodenectomy in the prevention of gastroduodenal artery(GDA)stump related delayed bleeding.Methods:Clinical data were collected from 45 patients undergoing the bio-artificial dura mater wrapping skeletonized hepatic artery during pancreatoduodenectomy from Oct 2022 to Apr 2023 at Department of General Surgery, the Affiliated Hospital of Xuzhou Medical University.Results:Among the 45 patients, the bio-artificial dura mater was used to completely wrap the GDA stump and part of the common hepatic artery and the proper hepatic artery. The mean operative time was (308.1±93.1) min, the mean wrapping artery time was (18.7±7.5) min. Clinically relevant postoperative grade B pancreatic fistula (CR-POPF) occurred in 6 cases (13.3%), and intra-abdominal infection in 2 cases (4.4%).The rate of bile leakage was 2.2%.There were no second surgical operation, nor perioperative death. Postoperative delayed bleeding occurred in one case (2.2%) on the right hepatic artery branch near the hepatic portal. No pseudoaneurysm formation, nor bleeding occurring in any of the arteries wrapped by bio-artificial dura mater (including the GDA stump) after PD. There were no postoperative hepatic artery wrapping complications, such as hepatic artery stenosis, mesh-associated fluid accumulation and infection.Conclusion:Bio-artificial dura mater wrapping skeletonized hepatic artery technique in the process of pancreaticoduodenectomy can reduce the risk of delayed bleeding due to erosion of GDA stumps in case of post-PD pancreatic fistula.
