ABSTRACT

OBJECTIVE To explore the value of providing pharmaceutical service related to risdiplam in direct-to-patient (DTP) pharmacies. METHODS The follow-up data of spinal muscular atrophy (SMA) patients who purchased and used risdiplam from Shangyao Yunjiankang Yiyao Pharmacy (Shanghai) Co., Ltd. from May 2021 to January 2023 were collected. The medication information, therapeutic efficacy and the occurrence of adverse events were retrospectively analyzed. RESULTS A total of 42 prescriptions were checked by pharmacists in the DTP pharmacies, and 7 prescriptions were found to be unreasonable (16.7%, 7/42), which were corrected after the timely intervention. During the follow-up management, pharmacists replied to 4 patients (9.5%, 4/42) regarding medication consultation about medication requirements and adverse events. Two patients with type Ⅰ SMA experienced adverse events: one of them presented with fever and the other presented with skin dryness with darkening. Both of them were grade Ⅰ toxic reactions and generally did not require clinical treatment. Considering that the patient sustained low-grade fever for a long time, the pharmacist suggested symptomatic treatment under the guidance of the doctor. CONCLUSIONS Pharmacists in DTP pharmacies conducting follow-up management of risdiplam use for rare disease SMA patients can help promote rational, standardized medication for patients.

ABSTRACT

Objective To establish a high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method for simultaneous determination of sodium valproate and vancomycin in human serum. Methods Valproic acid-d6 and kanamycin B were used as the internal standard of sodium valproate and vancomycin, the serum samples were treated by acetonitrile precipitation protein method. The mobile phase was 0.1% formic acid aqueous solution-acetonitrile for gradient elution. The flow rate was 0.5 ml/min, with column temperature at 25 ℃. The sample volume was 4 μl and total analysis time was 12 min. The positive and negative ion mode was monitored by electrospray ion source and the multiple reaction monitoring mode was used for quantitative analysis. The specificity, standard curve, lower limit of quantification, precision, recovery, matrix effect, and stability of the method were examined. Results Sodium valproate and vancomycin had good linear relationships in the range of 1 - 200 μg/ml and 0.5 - 100 μg/ml, respectively. The quantitative lower limits were 1 μg/ml and 0.5 μg/ml, respectively. The extraction recoveries were above 70%. The inter- and intra-batch precision RSD values were less than 10%. The stability was good and there was no obvious matrix effect. Conclusion This method is simple, quick, sensitive, specific and accurate, which could be used to simultaneously determine the concentration of sodium valproate and vancomycin in human serum.

ABSTRACT

Objective:To establish a model for predicting the mental health status of nurses based on machine learning algorithm.Methods:In February 2020, the nurses from Shantou Central Hospital and Cancer Hospital of Shantou University Medical College were recruited by convenience sampling, investigated using the Self-reporting Inventory, Coping Style Questionnaire, Social Support Rating Scale and Work Attitude Scale. Mental health status was treated as a dichotomous variable, and candidate predictors were screened out by univariate and multivariate Logistic regression analysis. The subjects were randomly divided into a training set (80%) and a test set (20%). Then five prediction models of nursing staff mental health status were constructed using the five machine learning methods (Logistic Regression, Artificial Neural Network, C5.0 Decision Tree, Bayesian Network and Support Vector Machine), verified and compared to screen out the model with the highest predictive efficiency.Results:A total of 415 nurses were enrolled, and the positive detection rate of mental health symptoms was 20.48%. According to univariate and multiple Logistic regression analysis, candidate predictors were work attitude ( OR=1.098, 95% CI 1.028-1.174), self-accusation ( OR=7.703, 95% CI 2.014-29.468), problem-solving( OR=0.131, 95% CI 0.025-0.686), the number of night shifts per month ( OR=0.204, 95% CI 0.073-0.573)and support availability ( OR=0.830, 95% CI 0.701-0.984). The accuracy of prediction of Logistic Regression, Artificial Neural Network, C5.0 Decision Tree, Bayesian Network and Support Vector Machine were 84.21%, 85.53%, 82.89%, 78.95%, 84.21%. The area under the ROC curve was 0.801, 0.825, 0.777, 0.583, 0.774. Artificial Neural Network was significantly more effective than Logistic regression, C5.0 Decision Tree, Bayesian Network and Support Vector Machine (DeLong test, P<0.05). Conclusions:The machine learning based predictive models for nursing staff mental health status has higher predictive value, which can be applied into nursing staff mental health screening decisions to accurately grasp its dynamic changes, early identification of high-risk mental health abnormalities and early intervention. Work attitude, self-accusation, problem-solving, the number of night shifts per month and support availability was predictors to construct predictive models.

ABSTRACT

Objective To characterize myocardial metabolism using positron emission tomography (PET) in porcine models of ventricular fibrillation cardiac arrest (VFCA) and asphyxiation cardiac arrest (ACA) after resuscitation.Methods Thirty-two healthy miniature pigs were randomized into two groups.The pigs of VFCA group (n =16) were subject to programmed electric stimulation to create a ventricular fibrillation cardiac arrest,and the pigs of ACA group (n =16) were subjected to endotracheal tube clamping to establish a cardiac arrest (CA).Once modeling was established,pigs with CA were left untreated for a period of 8 min.Two minutes following initiation of cardiopulmonary resuscitation (CPR),defibrillation was attempted until the restoration of spontaneous circulation (ROSC) was achieved or animals died.To assess myocardial metabolism,PET was performed before modeling,4 hrs and 24hrs after ROSC.To analyze 18F-FDG myocardial uptake in PET,the maximum standardized uptake value (SUVmax)) was measured.Results ROSC was obtained in 100% of pigs in VFCA group and only 50% in ACA group.The average survival time in VFCA pigs was significantly longer than that in ACA pigs (22.63 ± 0.95) hvs.(8.75 ± 2.54) h,P <0.01.VFCA pigs had better mean arterial pressure and cardiac output after ROSC than ACA pigs.Myocardial metabolism imaging using PET demonstrated that myocardial metabolism injuries after ACA were more severe and widespread than those after VFCA at 4 hrs and 24hrs after ROSC and SUVmax) was much higher in VFCA group than that in ACA group [4 h after ROSC:(1.9 ± 0.3) vs.(1.0 ± 0.4),P < 0.01;24 hafterROSC:(2.4±0.6) vs.(1.2±0.5),P<0.01].Conclusions Compared with VFCA,ACA causes more severe cardiac metabolism dysfunction associated with less successful resuscitation and shorter survival time;therefore they should be treated as different pathological entities.

ABSTRACT

Background and purpose: Malignant tumors often relapsed or metastasized after first-line chemotherapy and needed second-line or above treatment. We conducted this study to deifne the maximum-tolerated dose (MTD) of lobaplatin with ifxed docetaxel for Chinese patients in previously treated solid tumors. Methods:Escalating doses of lobaplatin with fixed docetaxel were administered in a modified Fibonacci sequence. The initial doses were lobapla-tin 30 mg/m2 and docetaxel 60 mg/m2, respectively. Escalating doses was 5 mg/m2. The regimen was repeated every 21 days. If no dose-limiting toxicity (DLT) was observed, the next dose level was applied. The procedures were repeated until DLT appeared. The MTD was declared to be one dose level below the level at which DLT appeared. Results:Seventeen patients received fifty-eight cycles chemotherapy at lobaplatin of levelⅠ(30mg/m2), levelⅡ(35 mg/m2)and levelⅢ(40 mg/m2). Cases of complete response (CR), partial response (PR), stable disease (SD) and progression disease (PD) for the whole group were 0, 1, 10 and 3, respectively. Response rate (RR, CR+PR) and disease control rate (DCR, CR+PR+SD) were 7.1%(1/14) and 78.6%(11/14), respectively. The most common toxicity was leukopenia. Three DLTs occurred in 3 patients in the whole group, including 2 DLTs in dose levelⅢ. We declared thus levelⅡwas MTD. Conclusion:MTD of lobaplatin in our re-search was 35 mg/m2 combined with fixed dose of docetaxel. This combination regimen was well tolerated.

ABSTRACT

Objective To conduct comparative study on the analgesic and anti-inflammatory effects as well as the acute toxicity of yunaconitine and 8-deacetyl-yunaconitine isolated from the processed products of Aconiti Knsnezoffii Radix.Methods The methods of hot plate test and writhing test were used to evaluate the analgesic effect. Anti-inflammation action was observed by the models of auricle swelling caused by dimethylbenzene. LD50 was determined by the method of Bliss.Results Yunaconitine and 8-deacetyl-yunaconitine have analgesia effect on the pain caused by hot-plate, but there were no statistically significant difference. The pain caused by acetic acid had obvious analgesic action. High and low dose of yunaconitine could significantly reduce the number of mice body torsion and extend the incubation period of pain in mice. The effect of 8-deacetyl-yunaconitine was remarkable only in the high dose. Compared with solvent group, there were little differences in inhibiting effect of auricle swelling caused by dimethylbenzene, and anti-inflammatory action was not exact. The poisonousness of yunaconitine was nearly 20 times of 8-deacetyl-yunaconitine.Conclusion Yunaconitine and 8-deacetyl-yunaconitine may be the analgesic medicine for peripheral analgesic effect. The poisonousness of 8-deacetyl-yunaconitine is less than yunaconitine, the effect is remarkable to the pain caused by acetic acid, and the security is high.

ABSTRACT

<p><b>BACKGROUND</b>Epinephrine has been used as a first-choice vasopressor drug for cardiac arrest (CA) since 1974. However, the administration of epinephrine is controversial. This study aims to compare the effects of Shen-Fu injection (SFI) and epinephrine on resuscitation outcomes in a porcine model of prolonged CA.</p><p><b>METHODS</b>Ventricular fibrillation (VF) was electrically induced. After 8 minutes of untreated VF and 2 minutes of chest compressions, 24 pigs were randomly divided into 3 groups (n = 8 per group): central venous injection of SFI (SFI group), epinephrine (EPI group), or saline solution (SA group). The haemodynamic status and oxygen metabolism parameters, including cardiac output, mean arterial pressure, left ventricular dp/dtmax and negative dp/dtmax, oxygen delivery (DO2), and oxygen consumption (VO2), were calculated.</p><p><b>RESULTS</b>SFI shortened the time to restoration of spontaneous circulation (ROSC) and decreased the number of shocks, similar to epinephrine. However, the mean arterial pressure, cardiac output, left ventricular dp/dtmax and negative dp/dtmax were significantly higher in the SFI group than in the EPI group at 4 and 6 hours after ROSC. VO2 and ERO2 decreased after ROSC and then increased. VO2 and ERO2 were significantly higher in the SFI group than in the EPI and SA groups after ROSC, while those were lowest in the EPI group among all groups.</p><p><b>CONCLUSIONS</b>SFI shortened the time to ROSC and decreased the number of shocks, similar to epinephrine. However, SFI improved oxygen metabolism, and produced a better hemodynamic status compared with epinephrine. SFI might be a potentially vasopressor drug for the treatment of CA.</p>

ABSTRACT

Objective To investigate the effects of parathyroid hormone (PTH) on the synthesis and secretion of collagen Ⅲ and fibronectin (FN), and the expressions of plasminogen activator inhibitor-1 (PAI-1), matrix metalloproteinase-1 (MMP-1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) mRNA in cultured human renal tubular epithelial cells (HK-2).Methods HK-2 cells were cultured in DMEM-F12 medium supplemented with 5% FBS. Cells were exposed to different concentrations of PTH (0, 10-12, 10-11, 10-10, 10-9, 10-8 mol/L) for 48 h, or 10-8 mol/L PTH at different time (0, 12, 24, 48, 72 h). The gene expressions of collagen Ⅲ,FN, PAI-1, MMP-1, and TIMP-1 were detected by semi-quantitative RT-PCR. The protein expression of collagen Ⅲ was detected by Western blotting. The level of FN in the supernatant was assayed by enzyme linked immunosorbent assay (ELISA). Results PTH increased gene expressions of collagen Ⅲ, FN, PAI-1 and TIMP-1 in a dose- and time-dependent manner, but decreased MMP-1 gene expression. Then the ratio of MMP-1/TIMP-1 was decreased. PTH increased the collagen Ⅲ protein expression in cultured HK-2 cells and the level of FN in the supernatant of cultured HK-2 cells in a dose- and time-dependent manner. Conclusion PTH can up-regulate PAI-1, TIMP-1 gene expressions, and down-regulate MMP-1 gene expression,resulting in elevation of extracellular matrix (ECM) synthesis and reductim of degradation.
