ABSTRACT
OBJECTIVE To evaluate the clinical effectiveness and safety of domestic generic and imported original clopidogrel for antiplatelet therapy in patients with acute coronary syndrome （ACS）. METHODS The clinical data of ACS patients in Nanjing Drum Tower Hospital of China Pharmaceutical University from January 2020 to June 2021 were retrospectively collected by using electronic medical record system， and the patients were divided into original drug group （321 cases） and generic drug group （328 cases） according to the drug use. Both groups were given dual antiplatelet therapy with clopidogrel and aspirin. The effectiveness and safety outcomes of the two groups were followed up for 12 months and compared， the related influential factors were analyzed. RESULTS Major adverse cardiovascular events （MACE） occurred in 16 and 22 patients in original drug group and generic drug group respectively， including nonfatal myocardial infarction （4 and 5 cases）， stroke （2 and 4 cases）， revascularization （8 and 3 cases）， cardiovascular related death （2 and 4 cases）， and all-cause death （4 and 6 cases）. There were 12 and 7 patients with major bleeding events， 38 and 29 patients with minor bleeding events， and 33 and 21 patients with non-bleeding adverse events. There was no statistically significant difference in the cumulative incidence of related events （P values of Log-Rank tests were all greater than 0.05）. Cox regression analysis showed that the use of generic clopidogrel did not increase the risk of MACE and major bleeding events in ACS patients [hazard ratio of 1.305 and 0.416， 95% confidence interval of （0.678， 2.512） and （0.155， 1.117）， respectively， P＞0.05]， and the combination of proton pump inhibitors （PPI） could reduce the risk of major bleeding events [hazard ratio of 0.196， 95% confidence interval of （0.063， 0.611）， P＜0.05]. CONCLUSIONS Compared with imported original drug， domestic generic clopidogrel has similar clinical effectiveness and good safety. Combined use of PPI may be a beneficial factor to reduce the occurrence of major bleeding events in patients.

ABSTRACT
Objective To evaluate the effects of antihypertensive drugs on renal function after percutaneous transluminal coronary angioplasty. Methods A retrospective analysis was performed on 193 patients who underwent percutaneous transluminal coronary angioplasty and took antihypertensive drugs regularly. Those patients were admitted to Nanjing Drum Tower Hospital during January 2020 to December 2020. The patients were divided into ACEI/ARB group, β-blockers, calcium channel blockers and hydration control group. All patients received routine hydration during the perioperative period. The changes of serum creatinine (Scr), blood urea nitrogen (BUN), estimated glomerular filtration rate(eGFR) and endogenous creatinine clearance rate (Ccr) before and after operation were compared. Results The incidence of CIN was 0% in four groups. Compared with the preoperative, there was no significant change in Scr and Ccr in every group. Except for the hydration control group, the BUN levels in three treated groups were reduced after postoperative. Specifically, the BUN reduction in β-blockers group has statistically significant difference compared to the hydration control group and CCB group. In addition, eGFR levels were significantly reduced in the β-blockers group. Preoperative Scr and Ccr levels in patients with high blood pressure (SBP≥140 or DBP≥90) were significantly different from the patients with normal blood pressure (SBP<140 and DBP<90). Conclusion The use of ACEI/ARB and CCB before percutaneous transluminal coronary angioplasty had no effect on renal function in the short term. β-blockers can slightly reduce renal function, especially in patients with high blood pressure, who should receive special attention.

CONCLUSIONS The multidisciplinary collaborative blood glucose management mode of the whole hospital with the participation of clinical pharmacists can control the blood glucose level of diabetic patients in the perioperative period more stably and effectively ，and has practical significance for the disease treatment and prognosis of patients.
ABSTRACT
Objective:This study aimed to determinate ten phenols (polydatin, resveratrol, rhein, emodin, chrysophanol, physcion, oxyresveratrol, 2,3,5,4'-tetera-hydroxystilbene-2-O-β-D-glucoside, (＋)-catechin and (-)-epicatechin) in Polygoni Cuspidati Rhizoma simultaneously based on the high-resolution multiple reaction monitoring (MRMHR) mode of ultra- performance liquid chromatography- quadrupole/time-of-flight mass spectrometry. Methods:The assay was performed on Waters ACQUITY UPLC BEH C18 (2.1 mm× 100 mm, 1.7 μm) column using acetonitrile-0.1% formic acid as the mobile phase. The flow rate was 0.2 ml/min. The MRMHR mode was adopted for quantification.Results:The analyzed compounds showed good linearity relationships ( r2>0.999). The intra- and inter-batch relative standard deviations were all <5% and the recovery rate was between 96.28%-103.23%. The content of polydatin was the highest, followed by resveratrol and emodin. However, the contents of chrysophanol and oxyresveratrol were relatively low and some batches were unqualified. The contents of analyzed compounds varied significantly among the ten batches. Conclusion:The proposed UPLC-Q/TOF-MS method was successfully established to determinate ten phenols in Polygoni Cuspidati Rhizoma simultaneously, which could provide technical support for the quality evaluation of Polygonum cuspidatum.
ABSTRACT
Stent-assisted coil embolization is a common endovascular treatment for ruptured/unruptured intracranial aneurysms. Stent implantation process can damage vascular endothelium, activate platelet and coagulation cascade, and then increase the risk of thrombosis. In order to reduce the risk of postoperative embolism, antiplatelet therapy is required. Among them, aspirin combined with clopidogrel dual antiplatelet therapy is a commonly used strategy. For patients with low response to clopidogrel, tigrelol or cilostazol can be used as an alternative drug. Although the scheme has been considered to be effective and safe, it is still controversial.
ABSTRACT
Objective:To investigate the distribution of blood concentration of cyclosporine (CsA) in patients with autoimmune disease in China, and analyze the effect of genetic polymorphisms of CsA-metabolizing enzymes, transporters and target enzymes on CsA levels.Methods:Steady-state trough blood concentrations (CsA C 0) of 193 patients' were detected by enzyme multiplied immunoassay technique. The genotype of the following sites in the included patients were sequenced by reverse transcription-polymerase chain reaction (RT-PCR): cytochrome P450 (CYP) 3A420230C>T, CYP3A56986A>G, ATP binding cassette subfamily B member 1 (ABCB1)1236C>T, ABCB12677G>T/A, ABCB13435C>T, cytochrome P450 oxidoreductase (POR) 1508 C>T and formyl peptide receptor 1 (FPR1) C>G were sequenced by RT-PCR. The influence of the gene polymorphism of the above-mentioned sites on the blood concentration of CsA was analyzed by using One-way analysis of variance (ANOVA), LSD- t test, Chi-square test. Results:One hundred and ninety-three patients included took CsA. The doses ranged from 75-200 mg/d and the patients' blood concentration distribution span was wide (33.0-313.8 ng/ml). The daily dose ( χ2=21.908, P=0.001) and age( F=4.262, P=0.006) had significant effect on the plasma concentration of CsA. ABCB12677G>T/A (rs2032582) gene polymorphism impacted on the unit dose of CsA C 0 (CsA C 0/d), CsA C 0/d [(0.81±0.42) ng·ml -1·mg -1] in wild type (GG) was higher than heterozygous mutant [GT/GA, (0.65±0.30) ng·ml -1·mg -1, P=0.023) and homozygous mutant (TT/AA/TA, (0.66±0.34) ng·ml -1·mg -1, P=0.039). Conclusion:The blood concentration of patients varies greatly among individuals. The Cold of CsA in wild type patients with ABCB12677G>T/A gene is signifficantly higher than that in mutant patients.
ABSTRACT
Rett syndrome (RTT) is a progressive neurodevelopmental disorder, mainly caused by mutations in MeCP2 and currently with no cure. We report here that neurons from R106W MeCP2 RTT human iPSCs as well as human embryonic stem cells after MeCP2 knockdown exhibit consistent and long-lasting impairment in maturation as indicated by impaired action potentials and passive membrane properties as well as reduced soma size and spine density. Moreover, RTT-inherent defects in neuronal maturation could be pan-neuronal and occurred in neurons with both dorsal and ventral forebrain features. Knockdown of MeCP2 led to more severe neuronal deficits as compared to RTT iPSC-derived neurons, which appeared to retain partial function. Strikingly, consistent deficits in nuclear size, dendritic complexity and circuitry-dependent spontaneous postsynaptic currents could only be observed in MeCP2 knockdown neurons but not RTT iPSC-derived neurons. Both neuron-intrinsic and circuitry-dependent deficits of MeCP2-deficient neurons could be fully or partially rescued by re-expression of wild type or T158M MeCP2, strengthening the dosage dependency of MeCP2 on disease phenotypes and also the partial function of the mutant. Our findings thus reveal stable neuronal maturation deficits and unexpectedly, graded sensitivities of neuron-inherent and neural transmission phenotypes towards the extent of MeCP2 deficiency, which is informative for future therapeutic development.
ABSTRACT
Objective:To determine the concentration of hydroxychloroquine (HCQ) and its active metabolite deethylhydroxychloroquine (DHCQ) in breast milk of lactating patients with autoimmune disease. To observe the safety of hydroxychloroquine in lactation period, and to explore the factors that may affect HCQ and DHCQ concentration in the milk.Methods:Lactating patients with autoimmune disease who have taken HCQ for at least 6 months were included in our study. A new high performance liquid chromatography (HPLC) method was established to detect HCQ and DHCQ levels in breast milk. Milk samples were collected at different time points: before taking the drug (0 hours), and 2 hours, 4 hours, 6 hours after taking the drug. In addition, the genotype of cytochrome CYP3A4*1G, CYP3A5*3 and CYP2D6*10 which were related to HCQ metabolism were tested by dideoxy chain termination method. Visual acuity, hearing and growth status of the patients' infants were followed up on a regular basis. T-test, one-way ANOVA and Pearson's test were used for data analysis. Results:In 15 patients, the average concentration of HCQ and DHCQ in the milk of patients taking 200 mg/d were (520±261) ng/ml and (177±112) ng/ml, respectively. While the average concentration of HCQ and DHCQ in the milk of patients taking 400 mg/d were (1 036±374) ng/ml and (397±271) ng/ml, respectively. The peak of HCQ level for 11 patients was at 4 hour after taking the drug, while the others' were at 2 hour. The breast-fed infants did not show any abnormal symptoms of hearing, vision and growth. However, cytochrome gene polymorphism did not affect the peak of HCQ and DHCQ.Conclusion:The concentration of HCQ and DHCQ in breast milk is positively correlated to the dosage. The peak level of HCQ milk is 4 hours after taking the drug. The levels of HCQ and DHCQ at 6 hours are similar as those in the whole blood. It is suggested that patients who take HCQ can feed 4 hours after taking the drug to reduce the HCQ and its active metabolites being absorbed by infants. However, the impact of HCQ on infant safety and gene polymorphism of CYP on milk concentration among individuals needs to be further verified in large sample studies and long-term follow-up.
ABSTRACT
Objective:To conduct a meta-analysis of clinical data to investigate the relationship between incretins and fracture in order to provide individualized hypoglycemic agents for type 2 diabetic patients with osteoporosis.Methods:PubMed, Embase, Web of Science, and Cochrane databases were searched up to January 1, 2018 for randomized controlled trials(RCTs)and the relationship between incretins and fracture was explored by meta-analysis.Results:The meta-analysis showed that the use of incretin was not associated with fracture risk compared with placebo or other positive hypoglycemic agents( OR 0.972, 95% CI 0.876-1.079). But in the subgroup analysis, 100 mg/d sitagliptin( OR 0.495, 95% CI 0.304-0.806)or 1.8 mg/d liraglutide( OR 0.621, 95% CI 0.413-0.933)reduced fracture risk. Conclusions:Meta-analysis shows no increase in the incidence of fracture events after the use of incretin. 100 mg/d sitagliptin or 1.8 mg/d liraglutide may exert protective effects on bone metabolism. However, the included data are from the reports of fracture adverse reactions in RCT studies, and large-scale clinical studies are needed to confirm these findings.
ABSTRACT
@#Adverse drug reaction(ADR)reports are acting as primary sources for post-marketing drug safety evaluation, which have important reference value for drug safety evaluation. In this article, bidirectional gated recurrent unit, a kind of deep learning method, was applied as the model for relation extraction of drugs and adverse reactions in free-text section of ADR descriptions in Chinese ADR reports, with attention as well as character embedding and word segmentation embedding added into the network. The experimental results showed that our model achieved good performance in the classification task of confirming the relationship of “Drug-ADR” pair(denial, likely, direct and post-therapy)in the ADR description, and the final model achieved an F-value of 87. 52%. The extracted information can assist in evaluating ADR reports and at the same time be utilized in tasks like statistical analysis of certain drugs and adverse events and ADR knowledge base construction to provide more research techniques for drug safety researches.
ABSTRACT
OBJECTIVE： To construct prediction model for initial dose of levothyroxine （L-T4） in differentiated thyroid cancer （DTC） patients after surgery. METHODS： A total of 100 DTC patients underwent surgery were selected from thyroid and breast surgery department in Nanjing Drum Tower Hospital. General information of patients such as gender， age， height， body mass， body mass index （BMI） and regular follow-up information after discharge were collected. Related data of thyroid function and adjusted dose of L-T4 were recorded. Single factor variance analysis and t-test were used to analyze the predictors that had significant correlation with the initial dose of L-T4. The prediction model of L-T4 initial dose was established by linear regression analysis， and was verified by prospective experiments. RESULTS： The initial dose of L-T4 in DTC post-surgery patients were significantly correlated with age （P＝0.01，F＝3.993）， body weight （P＜0.001，F＝6.910） and BMI （P＜0.001，F＝7.698）. Linear regression analysis showed that prediction model of initial dose of L-T4 was L-T4（μg/kg）＝2.971-0.033×BMI-0.005×age. DTC post-operative patients were given L-T4 empirically， and only 16％ （16/100） of the patients met the criteriaat the first follow-up of thyroicl function. In the validation test， L-T4 was given at the initial dose calculated by the prediction model， and 63.7％ （44/69） of the patients reached the standard at the first follow-up. CONCLUSIONS： The established prediction model of L-T4 initial dose after DTC surgery has a certain practicality.

ABSTRACT
The mammalian central nervous system (CNS) is considered an immune privileged system as it is separated from the periphery by the blood brain barrier (BBB). Yet, immune functions have been postulated to heavily influence the functional state of the CNS, especially after injury or during neurodegeneration. There is controversy regarding whether adaptive immune responses are beneficial or detrimental to CNS injury repair. In this study, we utilized immunocompromised SCID mice and subjected them to spinal cord injury (SCI). We analyzed motor function, electrophysiology, histochemistry, and performed unbiased RNA-sequencing. SCID mice displayed improved CNS functional recovery compared to WT mice after SCI. Weighted gene-coexpression network analysis (WGCNA) of spinal cord transcriptomes revealed that SCID mice had reduced expression of immune function-related genes and heightened expression of neural transmission-related genes after SCI, which was confirmed by immunohistochemical analysis and was consistent with better functional recovery. Transcriptomic analyses also indicated heightened expression of neurotransmission-related genes before injury in SCID mice, suggesting that a steady state of immune-deficiency potentially led to CNS hyper-connectivity. Consequently, SCID mice without injury demonstrated worse performance in Morris water maze test. Taken together, not only reduced inflammation after injury but also dampened steady-state immune function without injury heightened the neurotransmission program, resulting in better or worse behavioral outcomes respectively. This study revealed the intricate relationship between immune and nervous systems, raising the possibility for therapeutic manipulation of neural function via immune modulation.
ABSTRACT
Objective:To observe the effect of clinical pharmacists on the pain education in the patients with fracture. Methods:A total of 122 fracture patients with ASAⅠ/Ⅱaged 18-80 years were randomly divided into the intervention group (n=61) and the control group(n=61). The control group received the conventional orthopedic treatment..Flurbiprofen was injected for the postopera-tive analgesia,and if the pain VAS score was above 6,pethidine solution was given at the dose of 50 mg immediately. Based on the conventional treatment,the patients in the intervention group were educated by clinical pharmacist one day before the surgery,and then strengthened education was given after the surgery.The pain VAS score,and sleeping quality at 6h,24h,48h and 72h and satisfaction of pain management were compared between the groups.Results:The VAS score of the intervention group was significantly lower than that of the control group at 6 h,24 h,48 h and 72 h after the operation (P<0.05). The scores of sleeping quality in the intervention group at 6 h and 24 h after the operation were higher than those in the control group (P<0.05). The scores of patients' satisfaction were significantly higher in the intervention group than those of the control group (P<0.05). Conclusion: The clinical pharmacist's pain education can improve the degree of pain control and sleeping quality,increase the patients' satisfaction with pain control to a cer-tain extent.
ABSTRACT
OBJECTIVE:To investigate the effects of different diuretic regimens on related indicatora in hepatocellular carcino-ma patients after hepatic resection. METHODS:A total of 60 hepatocellular carcinoma patients undergoing hepatic resection were randomly divided into study group (30 cases) and control group (30 cases). After surgery,study group was given Spironolactone tablet 100 mg+Furosemide tablet 40 mg,qd,after breakfast;Control group was given Spironolactone tablet 100 mg orally,bid,af-ter breakfast and at 16:00+Furosemide tablet 20 mg,qd,after breakfast. Electrolyte,liver and renal function of 2 groups were re-checked every 3 days;diuretic regimen was adjusted according to body weight and volume of liquid intake and output. The effec-tiveness indexes of diuretic treatment were observed in 2 groups,such as the decrease of body weight,case number of effective di-uretic treatment,frequency of intravenous dieresis,frequency of hydroxyethl starch use,frequency of night arination,postoperative hospitalization stay,the time of ascites extinction;serum sodium,serum potassium,serum creatinine,blood urea nitrogen,serum al-bumin,ALT,AST,GGT,the occurrence of ADR were observed before and after treatment. RESULTS:The nocturnal micturition frequency of study group was significantly lower than that of control group,with statistical significance (P<0.05). There was no significant difference in the decrease of body weight,response rate of diuretic treatment,frequency of intravenous dieresis,frequen-cy of hydroxyethyl starch use,postoperative hospitalization stay or the time of ascites extinction between 2 groups(P>0.05). After treatment,the levels of serum sodium and serum albumin in 2 groups were decreased significantly,compared to before treatment;the levels of blood urea nitrogen,serum potassium and ALT,AST,GGT in 2 groups were significantly higher than before treat-ment,with statistical significance(P<0.05). There was no statistical significance in the levels of serum sodium,serum potassium, blood urea nitrogen,serum albumin or ALT,AST,GGT between 2 groups(P>0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Both two diuretic regimens can effectively avoid the occurrence of postoperative ascites formation and related complication in patients hepatocellular carcinoma after hepatic resection. The drug regi-mens of spironolactore 100 mg,qd+furosemide 40 mg,qd after breakfast can significantly reduce nocturnal micturition frequency and improve medication compliance.

ABSTRACT
Objective: To established a near-infrared spectroscopy quantitative model for the rapid determination of volatile oils from Rhizoma wenyujin concisum. Methods:Firstly, the volatile oils from Rhizoma wenyujin was determined by the distillation method described in Chinese Pharmacopoeia. The quantitative calibration model was established and optimized by fourier transformation near-infrared spectroscopy ( FT-NIR) combined with partial least square ( PLS) regression. The calibration model was evaluated by the coef-ficient (r), root-mean-square error of calibration (RMSEC) and root mean square of cross-validation (RMSECV) of the calibration model as well as the root mean square of prediction ( RMSEP) of prediction model. Results: In the combination of FT-NIR and PLS regression, the spectrum of 7189-4227 cm-1 , 8813-7478 cm-1 and"second spectrum+MSC" were chosen to establishe and optimize the quantitative calibration model. For the quantitative calibration model, the r, RMSEC and RMSECV of volatile oils was 0. 9769, 0. 0907 and 0. 3773, respectively. For the prediction model, the r and RMSEP of volatile oils was 0. 9053 and 0. 1960, respective-ly. Conclusion:The established near-infrared spectroscopy quantitative model is relatively stable, accurate and reliable in the simulta-neous quantitative analysis of volatile oils, and is expected to be used for the rapid determination of volatile oils from Rhizoma wenyujin concisum.
