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.

Advantages of Chinese Medicine in Treating Dominant Disease： Benign Prostatic Hyperplasia / 中国实验方剂学杂志

China Association of Chinese Medicine organized specialists in andrology of Chinese and western medicine to explore the population and treatment stage of benign prostatic hyperplasia （BPH） with Chinese medicine as the leading therapy. Chinese medicine has great advantages in the treatment of benign prostatic hyperplasia. However， it is necessary to make clear the stage when Chinese medicine or modern medical treatment can be used as the leading therapy， and the conditions under which Chinese and western medicine can be combined to achieve the best treatment efficacy. The specialists agreed Chinese medicine as the leading therapy for the treatment of BPH in the following populations or conditions： the elderly and weak patients with basic diseases， BPH symptoms， and cannot tolerate anesthesia and surgery， the patients with BPH symptoms and cannot tolerate the adverse reactions or the possible adverse reactions of western medicine； the patients with mild ［international prostatic symptom score （IPSS） ≤ 7］ or moderate lower urinary tract symptoms （IPSS ≥ 8） and the quality of life not significantly affected， the patients with bladder detrusor hypofunction， bladder dysfunction and cannot be treated surgically， or with incomplete bladder emptying after surgical treatment； the BPH patients with prostatitis as the main clinical manifestation， the patients with non-acute complications after operation. BPH is one of the dominant diseases in urology and andrology of Chinese medicine， and the symptoms， complications， and prognosis of BPH patients need to be fully considered during the clinical treatment. When Chinese medicine is taken as the leading therapy， it is essential to regularly review the serum level of prostate-specific antigen to exclude the possibility of prostate cancer， and apply Chinese medicine for full treatment course and cycle. At the same time， Chinese and western medicine can be combined to achieve the most effective， convenient， economical， and satisfactory treatment， which can carry forward the advantages of Chinese medicine in treating this disease.

Chinese Expert's Perspectives on Andrological Diseases Responding Specifically to Traditional Chinese Medicine / 中国实验方剂学杂志

In recent years， the incidence rate of andrological diseases has shown a significant growth trend. Considering the unavailability of a perfect theoretical system for andrology in traditional Chinese medicine （TCM） and the complex pathogenesis despite of the limited types of andrological diseases， it is necessary to improve the clinical efficacy of andrological diseases so as to satisfy the needs of patients. Therefore， the China Association of Chinese Medicine （CACM） organized the andrologists of TCM and western medicine and the outstanding young clinicians to discuss the andrological diseases responding specifically to TCM or integrated TCM and western medicine， such as chronic prostatitis， male infertility， benign prostatic hyperplasia， erectile dysfunction， and premature ejaculation， determine their diagnostic criteria in western medicine， and standardize the specifications for TCM diagnosis and treatment based on syndrome differentiation， thus formulating recognized and integrated diagnosis and treatment protocols. Apart from proposing suggestions on the treatment of such andrological diseases with TCM and western medicine， the experts have also figured out the andrological diseases responding specifically to TCM， the optimal intervention time of TCM and western medicine， and the suitable measures including surgery. The resulting consensus helps to better guide the formulation of accurate， personalized， and optimized treatment plans in clinical practice and improve the diagnosis and treatment effects of andrological diseases by giving full play to the advantages of TCM， which will in turn contribute to further innovation and development of TCM.

Development of a mechanism-based pharmacokinetic/pharmacodynamic model to characterize the thermoregulatory effects of serotonergic drugs in mice

We have shown recently that concurrent harmaline, a monoamine oxidase-A inhibitor (MAOI), potentiates serotonin (5-HT) receptor agonist 5-methoxy--dimethyltryptamine (5-MeO-DMT)-induced hyperthermia. The objective of this study was to develop an integrated pharmacokinetic/pharmacodynamic (PK/PD) model to characterize and predict the thermoregulatory effects of such serotonergic drugs in mice. Physiological thermoregulation was described by a mechanism-based indirect-response model with adaptive feedback control. Harmaline-induced hypothermia and 5-MeO-DMT-elicited hyperthermia were attributable to the loss of heat through the activation of 5-HTreceptor and thermogenesisthe stimulation of 5-HTreceptor, respectively. Thus serotonergic 5-MeO-DMT-induced hyperthermia was readily distinguished from handling/injection stress-provoked hyperthermic effects. This PK/PD model was able to simultaneously describe all experimental data including the impact of drug-metabolizing enzyme status on 5-MeO-DMT and harmaline PK properties, and drug- and stress-induced simple hypo/hyperthermic and complex biphasic effects. Furthermore, the modeling results revealed a 4-fold decrease of apparent SCvalue (1.88-0.496 µmol/L) for 5-MeO-DMT when harmaline was co-administered, providing a quantitative assessment for the impact of concurrent MAOI harmaline on 5-MeO-DMT-induced hyperthermia. In addition, the hyperpyrexia caused by toxic dose combinations of harmaline and 5-MeO-DMT were linked to the increased systemic exposure to harmaline rather than 5-MeO-DMT, although the body temperature profiles were mispredicted by the model. The results indicate that current PK/PD model may be used as a new conceptual framework to define the impact of serotonergic agents and stress factors on thermoregulation.

Expression Changes of Matrix Reconstitution-related Genes in Bone Marrow during 5-Fluorouracil-Induced Hemopoietic Injury and Their Significance / 中国实验血液学杂志

<p><b>OBJECTIVE</b>To explore the expression change of the genes related with matrix reconstitution during the injury and reconstitution of murine bone marrow following treatment with 5-fluorouracil (5-FU).</p><p><b>METHODS</b>C57BL/6 mice received intraperitoneal injection of 5-FU (200 mg/kg), and peripheral blood cell counts were monitored at 3, 6, 9, 15, 21, 27 days after treatment. Bone marrow cells were harvested at these times for total RNA extraction using TRIzol. Reverse transcriptions in combination with real-time PCR were performed for detecting expression of genes related with matrix reconstitution, including ECM-1, MMP-2, MMP-3, MMP-13 and TIMP-1.</p><p><b>RESULTS</b>After injection of 5-FU, the numbers of three line cells in peripheral blood (i.e. RBC, WBC and platelets) decreased and then recovered with differential dynamics. Similarly, RT-qPCR revealed that all the 5 detected gene expressions were significantly up-regulated during the injury. The mRNA expression of MMP-2 reached to peak at day 3 while the other genes reached to peak at day 6. MMP-3 has a low expression when compared with others, but its expression increased significantly after injury.</p><p><b>CONCLUSION</b>In 5-FU induced hematopoietic injury and reconstitution model, matrix reconstitution-related genes may play an important role in hematopoietic reconstitution, but different genes play different roles at various time, and cooperate with each other for hematopoietic reconstitution.</p>

A bibliometric study of scientific research conducted on second-generation antipsychotic drugs in Singapore

<p><b>INTRODUCTION</b>A bibliometric study was carried out to ascertain the volume and impact of scientific literature published on second-generation antipsychotic drugs (SGAs) in Singapore from 1997 to 2011.</p><p><b>METHODS</b>A search of the EMBASE and MEDLINE databases was performed to identify articles originating from Singapore that included the descriptors 'atypic* antipsychotic*', 'second-generation antipsychotic*', 'clozapine', 'risperidone', 'olanzapine', 'ziprasidone', 'quetiapine', 'sertindole', 'aripiprazole', 'paliperidone', 'amisulpride', 'zotepine', 'asenapine', 'iloperidone', 'lurasidone', 'perospirone' and 'blonanserin' in the article titles. Certain bibliometric indicators of production and dispersion (e.g. Price's Law on the increase of scientific literature, and Bradford's Law) were applied, and the participation index of various countries was calculated. The bibliometric data was also correlated with some social and health data from Singapore, such as the total per capita expenditure on health and gross domestic expenditure on research and development.</p><p><b>RESULTS</b>From 1997 to 2011, a total of 51 articles on SGAs in Singapore were published. Our results suggested non-fulfilment of Price's Law (r = 0.0648 after exponential adjustment vs. r = 0.2140 after linear adjustment). The most widely studied drugs were clozapine (21 articles), risperidone (16 articles) and olanzapine (8 articles). Division into Bradford zones yielded a nucleus occupied by the Journal of Clinical Psychopharmacology (6 articles) and the Singapore Medical Journal(4 articles). The analysed material was published in a total of 30 journals, with the majority from six journals. Four of these six journals have an impact factor greater than 2.</p><p><b>CONCLUSION</b>Publications on SGAs in Singapore are still too few to confirm an exponential growth of scientific literature.</p>

Distribution of tap1 and tap2 loci allelic and genotypic frequencies in Chinese Hans / 中国实验血液学杂志

This study was aimed to investigate the distribution and implication of tap1 (transporter associated with antigen processing) and tap2 loci allelic and genotypic frequencies. The distribution of tap1 and tap2 loci allelic and genotypic frequencies in 339 random samples of healthy Chinese Hans was analyzed by TaqMan PCR. Several genetic information about power of discrimination, cumulative DP, polymorphism information content, expected heterozygosity and observed heterozygosity were calculated. The results indicated that 5 tap1 alleles (tap1*0101, 020101, 020102, 0301 and 0401) and 4 tap2 alleles (tap2*0101, 0102, 0103 and 0201) were detected in all samples. 8 tap1 genotypes were found which account for 53.3% of the theoretic genotype and 6 tap2 genotypes were found which account for 60% of the theoretic genotype. The genotyping results of tap1 and tap2 both conform to the Hardy-Weinberg expectations (p > 0.05). Tap1*0101 (79.79%) and tap2*0101 (82.74%) are the most common alleles in Chinese Hans. It is concluded that tap1*0101 and tap2*0101 are most common alleles in Chinese Hans, tap1 and tap2 loci carry some power of individual discrimination and polymorphism information content. These two locl can be used for the research in the fields of human genetics, linkage analysis of genetic disease genes, paternity test and individual identification and so on.
