OBJECTIVE To standardize the use of sterile powder for injection redissolution solvent and intravenous drugs diluent solvent， and ensure the safety of clinical drug use. METHODS The intravenous drug resolvent generation system and the intravenous drug solvent incompatibility rules library were constructed and operated by prescription-checking pharmacist team in our hospital by formulating a list of intravenous drugs needed to be dissolved with sterilized water for injection and a contraindication list of intravenous solvent compatibility. The unreasonable medical orders reviewed and intervened in our hospital from January to April 2023 （before the implementation of the intravenous drug solvent incompatibility rules library） and from May to August 2023 （after the implementation） were analyzed statistically to compare the number of unreasonable solvent selection orders， interception rate， and the success rate of pharmacists’ interventions for unreasonable solvent selection orders before and after the implementation. RESULTS Before the implementation of the solvent incompatibility rules library， a total of 5 229 groups of medical orders with unreasonable solvent selection in our hospital were identified， among which there were 1 204 groups of seriously unreasonable medical orders， with interception rate of 23.03% and the success rate of pharmacists’ intervention of 15.90%. After the implementation of the solvent incompatibility rules library， the total number of medical orders with unreasonable solvent selection was 3 258 groups， among which there were 1 148 groups of seriously unreasonable medical orders， with interception rate of 35.24% and success rate of pharmacists’ intervention of 24.83%， being significantly higher than before implementation （P＜0.01 or P＜0.001）. CONCLUSIONS The establishment and application of the intravenous drug resolvent generation system and the solvent incompatibility rules library can significantly increase the interception rate of unreasonable solvent selection orders and the success rate of pharmacists’ interventions, and ensure the safety of clinical drug use.

BACKGROUND: Patients with atrial fibrillation (AF) and prior stroke history have a high risk of cardiovascular events despite anticoagulation therapy. It is unclear whether catheter ablation (CA) has further benefits in these patients. METHODS: AF patients with a previous history of stroke or systemic embolism (SE) from the prospective Chinese Atrial Fibrillation Registry study between August 2011 and December 2020 were included in the analysis. Patients were matched in a 1:1 ratio to CA or medical treatment (MT) based on propensity score. The primary outcome was a composite of all-cause death or ischemic stroke (IS)/SE. RESULTS: During a total of 4.1 ± 2.3 years of follow-up, the primary outcome occurred in 111 patients in the CA group (3.3 per 100 person-years) and in 229 patients in the MT group (5.7 per 100 person-years). The CA group had a lower risk of the primary outcome compared to the MT group [hazard ratio (HR) = 0.59, 95% CI: 0.47-0.74, P < 0.001]. There was a significant decreasing risk of all-cause mortality (HR = 0.43, 95% CI: 0.31-0.61, P < 0.001), IS/SE (HR = 0.73, 95% CI: 0.54-0.97, P = 0.033), cardiovascular mortality (HR = 0.32, 95% CI: 0.19-0.54, P < 0.001) and AF recurrence (HR = 0.33, 95% CI: 0.30-0.37, P < 0.001) in the CA group compared to that in the MT group. Sensitivity analysis generated consistent results when adjusting for time-dependent usage of anticoagulants. CONCLUSIONS In AF patients with a prior stroke history, CA was associated with a lower combined risk of all-cause death or IS/SE. Further clinical trials are warranted to confirm the benefits of CA in these patients.

To identify the bitter compounds of real-world Xiaoer Ganmao Oral Liquid sugar-free intermediates, an integrated strategy has been developed by using ultra-high performance liquid chromatography with linear ion trap-Orbitrap mass spectrometry (UHPLC-LTQ-Orbitrap MSⁿ) method and BitterX database prediction. The chromatographic operating conditions were as follows, chromatographic column: Acquity UPLC BEH C₁₈ (100 mm × 2.1 mm, 1.7 μm), mobile phase: 0.1% formic acid-water solution (A)-acetonitrile (B) with gradient elution. The data were collected in positive and negative ion modes, respectively. The accurate molecular mass and structural information of the target compounds were obtained based on quasi-molecular ions and fragmentation ions provided by high-resolution mass spectrometry. The compounds were identified by combining retention time, reference substances, reports, and other relevant data, and a total of 57 constituents including flavonoids, alkaloids, and phenylpropanoids were finally identified. Further, the BitterX database was used to predict binding probability of compounds to bitter receptors and identify potential bitter critical quality attributes, finally 33 potential bitter compounds, including kukoamine A and linarin, were predicted. This study comprehensively characterized the material basis of Xiaoer Ganmao Oral Liquid sugar-free intermediates, it provides an effective method for bitter compound screening and a reference for further improving the undesirable taste of Xiaoer Ganmao Oral Liquid.

BACKGROUND: Rheumatoid arthritis (RA), a chronic systemic autoimmune disease, is characterized by synovitis and progressive damage to the bone and cartilage of the joints, leading to disability and reduced quality of life. This study was a randomized clinical trial comparing the outcomes between withdrawal and dose reduction of tofacitinib in patients with RA who achieved sustained disease control. METHODS: The study was designed as a multicenter, open-label, randomized controlled trial. Eligible patients who were taking tofacitinib (5 mg twice daily) and had achieved sustained RA remission or low disease activity (disease activity score in 28 joints [DAS28] ≤3.2) for at least 3 months were enrolled at six centers in Shanghai, China. Patients were randomly assigned (1:1:1) to one of three treatment groups: continuation of tofacitinib (5 mg twice daily); reduction in tofacitinib dose (5 mg daily); and withdrawal of tofacitinib. Efficacy and safety were assessed up to 6 months. RESULTS: Overall, 122 eligible patients were enrolled, with 41 in the continuation group, 42 in the dose-reduction group, and 39 in the withdrawal group. After 6 months, the percentage of patients with a DAS28-erythrocyte sedimentation rate (ESR) of <3.2 was significantly lower in the withdrawal group than that in the reduction and continuation groups (20.5%, 64.3%, and 95.1%, respectively; P  < 0.0001 for both comparisons). The average flare-free time was 5.8 months for the continuation group, 4.7 months for the dose reduction group, and 2.4 months for the withdrawal group. CONCLUSION: Withdrawal of tofacitinib in patients with RA with stable disease control resulted in a rapid and significant loss of efficacy, while standard or reduced doses of tofacitinib maintained a favorable state.

BACKGROUND: Filiform needle acupuncture (FNA), the most classical and widely applied acupuncture method based on traditional Chinese medicine theory, has shown a promising effect in the treatment of allergic rhinitis (AR). OBJECTIVE: To evaluate the efficacy, safety, cost-effectiveness, and patient preference of FNA in the treatment of AR by comparing FNA with sham acupuncture, no treatment, and conventional medication. SEARCH STRATEGY: Eight electronic databases were systematically searched from inception to October 14, 2021. Additional studies were acquired from clinical trial registration platforms and reference lists. INCLUSION CRITERIA: Randomized controlled trials were included if they compared FNA with either sham acupuncture, no treatment or conventional medication for AR. DATA EXTRACTION AND ANALYSIS: Two researchers extracted data independently of each other using a predesigned data acquisition form, and results were cross-checked after completion. The primary outcome was symptom score (Total Nasal Symptom Score or Visual Analogue Scale), and the secondary outcomes were the AR control questionnaire, quality of life (QoL) score (Different versions of Rhinoconjunctivitis Quality of Life Questionnaire), medication score (use of rescue medication), mental health score, total IgE, adverse event rate, clinical economic indicators, and patient satisfaction score. Standardized mean difference (SMD) or mean difference (MD) with 95% confidence interval was used to calculate the effect size for continuous data, while risk ratio with 95% CI was used for dichotomous data. RESULTS: Thirty studies were included in this review. Compared with sham acupuncture, FNA significantly reduced the symptom score (SMD: -0.29 [-0.43, -0.15]), AR's impact on QoL (SMD: -0.23 [-0.37, -0.08]) and medication score (SMD: -0.3 [-0.49, -0.11]). Compared with no treatment, FNA dramatically reduced the symptom score (SMD: -0.8 [-1.2, -0.39]) and AR's impact on QoL (SMD: -0.82 [-1.13, -0.52]). There were no increased rates of adverse events with FNA compared to sham acupuncture and no treatment. FNA increased patient satisfaction and may be cost-effective. Most pieces of evidence from the above two comparisons were of high confidence. Moreover, FNA significantly outperformed conventional medication in reducing the symptom score (SMD: -0.48 [-0.85, -0.1]) and displayed a lower rate of adverse events, but the quality of evidence was very low. CONCLUSION FNA is an effective and safe intervention for AR and can help with symptom relief, QoL improvement, reducing medication usage, and increasing patient satisfaction. Further studies are needed to verify its cost-effectiveness and superiority over conventional medication and the best therapeutic strategies.

Objective: To investigate the effect of berberine on programmed necrosis of hepatocytes induced by metabolic-associated fatty liver disease (MAFLD) in mice and its related molecular mechanism. Methods: Twenty male C57BL/6N mice were randomly divided into four groups (n=5 in each group): control group (S), fatty liver group (H), berberine group(B), nuclear factor erythroid 2-related factor 2 inhibitor group (Nrf2), and all-trans-retinoic acid (ATRA) group (A). Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), triglycerides (TG), total cholesterol (TC), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) concentrations were detected at the end of week 12 to calculate fatty liver index (liver mass/body mass ratio). Liver tissue was stained with HE, Masson and Oil Red O, and SAF score was used to evaluate the degree of liver injury. The expression levels of hepatic programmed necrosis-related proteins, namely receptor-interacting protein kinase 3 (RIPK3), phosphorylated mixed series protease-like domain (p-MLKL) and Nrf2 were detected by Western blot method. One-way ANOVA was used for intragroup comparisons and LSD-t tests were used for intergroup comparisons. Results: Compared with S group, H group serum ALT, AST, LDH, TG, TC, TNF-α, IL-1β levels and fatty liver index were significantly increased. The liver tissue was filled with vacuolar-like changes and inflammatory cell infiltration. Numerous red lipid droplets were observed with oil red O staining. Collagen fiber hyperplasia was evident with Masson staining. SAF scores (6.60 ± 0.55 and 0.80 ± 0.45) were significantly increased. The expressions of RIPK3 and p-MLKL were up-regulated. Nrf2 level was relatively increased, and the differences were statistically significant (P < 0.05). Compared with H group, berberine intervention group liver biochemical indexes, lipid levels, pro-inflammatory mediator expression, fatty liver index, and SAF score were significantly reduced, and the expression of RIPK3 and p-MLKL were down-regulated, while Nrf2 levels were further increased, and the differences were statistically significant (P<0.05). Compared with B group, treatment with Nrf2 inhibitor had antagonized the protective effect of berberine on fatty liver. Serum ALT, AST, LDH, TG, TC and TNF-α, IL-1β levels, fatty liver index, and SAF scores were significantly increased and the expressions of RIPK3 and p-MLKL were relatively increased, and the differences were statistically significant (P < 0.05). Conclusion: Berberine can significantly improve the metabolic-associated fatty liver disease injury in mice, and its mechanism is related to activation of Nrf2 and inhibition of programmed necrosis of hepatocytes.

Objective:To summarize the medium-term outcomes of single kidney transplantation from senile deceased donors aged above 65 years.Methods:Forty-three kidney recipients from donors aged above 65(old-aged donor group, OAD) and 43 kidney recipients of the same age and gender from donors aged 18 to 49 years(standard-criteria donor group, SCD) were retrospectively reviewed.The survival outcomes of patients and grafts, renal functions, the incidence of delayed graft function(DGF)and other complications were recorded within the 3-year follow-up post-transplantation.Results:The 3-year patient survival rates were 95.3% both in OAD and SCD and the 3-year death-censored graft survival rates 92.7% and 97.6% respectively.The serum levels of creatinine were significantly higher in OAD than that in SCD( P<0.05). And lower estimated glomerular filtration rate(eGFR)was found in OAD as compared with SCD( P<0.05). No significant difference existed in the incidence of DGF(OAD 20.9% and SCD 18.6%, P>0.05), acute rejection (OAD 4.7% and SCD 2.3%, P>0.05)or proteinuria(OAD 27.9%and SCD 14.0%, P>0.05). Conclusions:Single kidney transplantation from old-aged deceased donors may achieve excellent medium-term survival outcomes of patients and grafts.It can expand the donor pool though kidney functions were not as good as those of SCD.
