Safety of butylphthalide and edaravone in patients with ischemic stroke: a multicenter real-world study / 老年心脏病学杂志（英文版）

BACKGROUND@#Butylphthalide (NBP) and edaravone (EDV) injection are common acute ischemic stroke medications in China, but there is a lack of large real-world safety studies on them. This study aimed to determine the incidence of adverse events, detect relevant safety signals, and assess the risk factors associated with these medications in real-world populations.@*METHODS@#In this study, data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021. Baseline confounders were eliminated using propensity score matching. The drugs' safety was estimated by comparing the results of 24 laboratory tests standards on liver function, kidney function, lipid level, and coagulation function. The drugs' relative risk was estimated by logistic regression. A third group with patients who did not receive NBP or EDV was constructed as a reference. Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV, respectively.@*RESULTS@#81,292 patients were included in this study. After propensity score matching, the NBP, EDV, and third groups with 727 patients in each group. Among the 15 test items, the incidence of adverse events was lower in the NBP group than in the EDV group, and the differences were statistically significant. The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results, whereas EDV had statistically significant effects on aspartate transaminase, low-density lipoprotein cholesterol and total cholesterol. Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count. EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, prothrombin time, and platelet count.@*CONCLUSIONS@#In a large real-world population, NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.

Evidence-based practice of standardized gastric lavage for acute organophosphorus pesticide poisoning / 中华护理杂志

Objective To formulate standardized program of gastric lavage for acute organophosphorus pesticide poisoning(AOPP) and evaluate the effects.Methods Evidence was obtained via evidence-based approach,and recommendations were formed.The standardized program of gastric lavage for AOPP was formulated and then applied to clinical practice.The effects were evaluated by examining indicators of success rate of catheterization,the first time of gastric lavage,the time of atropinization and total usage of atropine,ChE recovery time,hospital stay,rebound rate,adverse event rate.Results After implementation,the first time of gastric lavage,the time of atropinization,total usage of atropine,ChE recovery time,and hospital stay were significantly lower than the control group (P＜0.05).Conclusion Evidence-based practice of gastric lavage for AOPP can improve therapeutic effects,reduce adverse reactions,improve quality of nursing,and promote safety of medical care.

Comparison of clinical effects between the outside and under temporal muscle method in frontal-temporal cranioplasty by digital forming titanium mesh / 中国基层医药

ObjectiveTo compare the clinical effects of the outside and under temporal muscle titanium cranioplasty in mass frontal-temporal skull defect.MethodsClinical data of forty-two frontal-temporal skull defect pa tients who had cranioplasty with digital forming titanium nets were analyzed retrospectively.Two groups were divided according to the surgical method.Twenty-two cases underwent outside temporal and twenty cases under went temporal muscle titanium mesh.Compared with two groups of surgery condition( operation time,blood loss,titanium nail dos age) and postoperative complications( wound infection,subcutaneous effusion,epilepsy,intracranial hematoma,chew limited,facial paralysis) and the satisfaction rate of appearance discharged after one month.ResultsThe operation time of outside temporal muscle group was obviously less than under temporal muscle group( t =2.42,P ＜ 0.05 ),but the under temporal muscle group patients were more satisfied with the postoperative appearance ( x2 =36.31,P ＜0.05 ).There was no obvious difference of the postoperative complication between the two groups ( x2 =1.80,P ＞0.05 ).ConclusionBoth the outside and under temporal muscle method had its advantages and disadvantages.Operation methods selection should comprehensively and individually according to the specific condition of patients,surgi cal doctor's clinical experience.

Interaction between Warfarin and the Herbal Product Shengmai-Yin: A Case Report of Intracerebral Hematoma

A 71-year-old man was stable on warfarin (2.25 mg daily) therapy with an international normalized ratio (INR) of 1.8-2.2 after a heart valve replacement surgery. Recently, he consumed the liquid-like herbal product called shengmai-yin (10 mL daily) against medical advice. Seven days after the daily consumption of shengmai-yin, he was admitted to the intensive care unit because of consciousness disturbance [Glasgow Coma Scale (GCS) score 7] with an INR of 5.08. Head computed topography revealed intracerebral hematoma in the left temporoparietal region. Both warfarin therapy and the herbal product were withdrawn. At the same time, therapy with intravenous vitamin K1 40 mg was started. On the second day of admission, craniectomy was performed to remove the intacerebral hematoma under general anesthesia. He remained confused and restless for 2 days, but then showed progressive recovery in the consciousness level as well as motor and verbal functions. Shengmai-yin contains herbal ingredients that can interact with warfarin. The Drug Interaction Probability Scale (DIPS) indicated that warfarin and shengmai-yin were highly probable causes of intracerebral hematoma. Patients on warfarin therapy should be discouraged from taking herbal medicines, especially preparations that are already known to have antiplatelet and antithrombotic effects.

Epidemiology and Analysis of Sensitivity for Antibiotics of Bacteremia in Intensive Care Unit / 中华医院感染学杂志

OBJECTIVE To study the epidemiology and the sensitivity to antibiotics of bacteremia in intensive care unit,and provide the reference for the clinical antimicrobial agents usage. METHODS 465 cases of bacteremia from Jan 2005 to Dec 2007 in the First Affiliated Hospital,Medical College of Zhejiang University were retrospectively analyzed. RESULTS Totally 1465 strains of pathogens were isolated in three years,and the positive rates were 22.6%.From them 155 strains were fungi(10.6%),611 strains were Gram-positive bacteria(57.9%) and 392 strains were Gram-negative bacteria(37.1%).G + strains mainly included coagulase-negative Staphylococcus(CNS,43.0%) and Staphylococcus aureus(2.1%);the sensitive antibiotics were vancomycin and teicoplanin.G-strains mainly included Acinetobacter baumannii(8.6%);Stenotrophomonas maltophilia(6.6%);Pseudomonas(5.1%) and Klebsiella pneumoniae(5.3%),the sensitive antibiotics were cefoperazone/sulbactam. CONCLUSIONS The positive rates of blood culture are higher in intensive care unit than in others.We should pay more attention to CNS for its high infection rate.The sensitive antibiotics of G + are vancomycin and teicoplanin.The sensitive antibiotics of G-are cefoperazone/sulbactum.Antimicrobial therapy should be conducted according to susceptibility test.The candidemia caused by non-Candida albicans(NCA) is increaseing in recent 3 year.

Knocking-down of Nogo-A Gene Expression in PC12 Cell Line by Plasmid-based RNAi / 华中科技大学学报（医学）（英德文版）

To study the inhibitory effect of Nogo-A shRNA on cell line PC12, the Nogo-A shRNA (short hairpin RNA, or shRNA) was designed and synthesized. The annealed shRNA template was inserted into plasmid pGenesil-1 containing enhanced green fluorescent protein (EGFP) gene by gene cloning technique to generate eukaryotic expression vector. The recombinant plasmid was transfected into PC12 cells by lipofecamine2000 and the mRNA and protein expression level of Nogo-A gene was detected by RT-PCR and Western blotting 48 h after the transfection. Gene sequencing showed that that the Nogo-A shRNA eukaryotic expression vector was successfully constructed. No significant change was found in the Nogo-A mRNA and protein expression level in empty vector-transfected group as compared with controls (P＞0.05), while the expression level in shRNA-transfected group decreased significantly (P＜0.05). It is concluded that the pGenesil-1/Nogo-AshRNA recombinant plasmid can effectively suppress the expression of Nogo-A gene in PC 12 cells.
