Background Depressive symptoms have become a significant factor affecting the physical and mental health of the occupational population, and workers in petroleum refining enterprises face multiple stressors in their work environment. Objective To explore the impact of occupational noise exposure on depressive symptoms among workers in a petroleum refining enterprise. Methods This cross-sectional study was conducted in July 2024 using a questionnaire survey among workers of a petroleum refining enterprise in Hainan Province. Basic information of the subjects was collected. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to measure depressive symptoms, the Chinese version of the Pittsburgh Sleep Quality Index (PSQI) scale was used to assess sleep quality, and the Chinese version of the Effort-Reward Imbalance (ERI) scale was used to evaluate occupational stress. Chi-square test was employed to compare the differences in reporting depressive symptoms among populations with different characteristics. Binary logistic regression models were used to analyze the impact of occupational noise exposure and other factors on depressive symptoms. Results The overall positive rate of depressive symptoms in the study population was 42.7%. The results of the multifactor analysis indicated that compared with the control group, employees in both the low-exposure and high-exposure groups had elevated odds of depressive symptoms, with OR (95%CI) of 2.244 (1.131, 4.454) and 1.970 (1.009, 3.850), respectively. This association remained robust after adjusting for potential confounders, including gender, age, work tenure, and other occupational exposures. Additionally, female [OR (95%CI)=1.483 (1.039, 2.118)], exposure to benzene, toluene, or xylene [OR (95%CI)=1.621 (1.208, 2.174)], sleep disturbance [OR (95%CI)=3.772 (2.942, 4.838)], and occupational stress [OR (95%CI)=2.018 (1.575, 2.585)] were also significantly associated with higher odds of depressive symptoms. Conclusion The positive rate of depressive symptoms is relatively high among employees in this petrochemical enterprise, and occupational noise exposure may be a risk factor for depressive symptoms.

Objective:To understand the current status of financial toxicity in patients with heart failure and the factors affecting it, and to provide ideas for making personalized and informed decisions.Methods:Using a scoping review methodological framework, PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, VIP, Wanfang, and SinoMed Databases were searched and screened for relevant literature on financial toxicity in patients with heart failure, with a timeframe of January 1, 2014-October 31, 2023, respectively. Relevant literature was identified based on inclusion and exclusion criteria, and data were extracted, collected, summarized, and the findings were reported.Results:Ten literatures that met the inclusion and exclusion criteria were identified. The results showed 5 cross-sectional surveys, 2 qualitative studies, and 1 each of reviews, mixed studies and commentaries. Heart failure patients generally faced high levels of financial toxicity, the incidence and severity of patient financial toxicity varied somewhat between study outcomes. Factors influencing financial toxicity in heart failure patients included age, education level, family income level, discussion of medical costs with physicians, type of insurance the patient had, and occupational status.Conclusions:In the future, we can develop and apply a specialized assessment tool for financial toxicity in heart failure patients in China, further explore the factors affecting financial toxicity in heart failure patients, and formulate personalized treatment plans and financial support strategies for patients according to the influencing factors, so as to reduce the impact of financial toxicity on heart failure patients.

Childhood arterial ischemic stroke (AIS) refers to an ischemic stroke caused by intracranial artery stenosis or occlusion that occurs between the ages of 29 days and 18 years. Although relatively rare, AIS is an important cause of disability or death in children. The etiologies and risk factors for AIS in childhood are significantly different from those in adults. This article reviews the common causes and risk factors for AIS in childhood.

Objective:To investigate the effect and necessity of fine operation on the improvement of the preparation outcome of paclitaxel (albumin-binding) intravenous infusion for injection.Methods:The detailed refinement of the preparation method in the specification of paclitaxel (albumin-binding) for injection was developed. The fine operation of paclitaxel (albumin-binding) for injection mainly consists of two parts: The mixing method of solvent and drug: including syringe needle length into drug vial, solvent injection speed, state of drug waiting for dissolution, and the shaking speed of the drug vial. The method of extracting the dissolved liquid in the drug vial and injecting it into a 100 ml sterile empty 0.9% sodium chloride injection bottle: including the speed of refilling the 100 ml sterile empty 0.9% sodium chloride injection bottle, and restoring the pressure balance inside and outside the infusion bottle. The effect of fine operation on the preparation of paclitaxel (albumin-binding) for injection was evaluated by comparing the production of foam and the preparation time before and after the implementation of fine operation.Results:Before and after the implementation of fine operation, the foaming rate of the foam in the drug vial decreased from 28.57% (10/35) to 12.50% (12/96), the difference was statistically significant ( χ2 value was 4.471, P=0.029); and the foaming rate of the mixed liquid from the drug vial into the 100 ml sterile empty 0.9% sodium chloride injection bottle decreased from 46.15% (6/13) to 9.09% (3/33), the difference was statistically significant ( χ2 value was 8.140, P value was 0.004); and the preparation time of single drug was reduced by 3.37 minutes after the implementation of fine operation, the difference was statistically significant ( t value was 79.744, P<0.05). Conclusion:The preparation method of fine operation of paclitaxel (albumin-binding) for injection is operable, safe and reliable. After implementation, it can effectively reduce the production of foam in the drug vial and infusion bottle, improve the stability of drug preparation, shorten the preparation time, and ensure the safe, timely and effective medication for patients.

OBJECTIVE:To investigate the effects of blood concentration monitoring of cylosporin A(CsA) in patients with nephrotic syndrome(NS)on efficacy and safety. METHODS:The medical records of 154 NS patients receiving CsA and blood concentration monitoring in nephrology department of China-Japan Friendship Hospital during Jan. 2014-Aug. 2017 were analyzed retrospectively. The results of blood concentration monitoring in 63 adult inpatients with refractory NS receiving CsA for the first time within 6 months of initial treatment were analyzed statistically. The relationship of blood concentration monitoring with efficacy and safety was analyzed. RESULTS:The blood concentration of CsA in 154 patients were monitored for 512 times with an average of 3.32 times/person,and average blood concentration was(125.98±105.13)ng/mL. The patients with blood concentration of CsA＜100 ng/mL accounted for 44.14%. There was no statistical significance in average monitoring times or average blood concentration between male and female,average blood concentration of CsA among different age groups (P＞0.05). The blood concentration was monitored for 237 times in 63 adult inpatients with refractory NS receiving CsA for the first time within 6 months of initial treatment(induction period). Average blood concentration of effective group were significantly higher than ineffective group;the proportion of effective group with blood concentration＜100 ng/mL was significantly lower than that of ineffective group,with statistical significance (P＜0.05). Among 63 patients,17 patients suffered from ADR (the incidence of ADR was 26.98%). The average blood concentrations of ADR patients were significantly higher than those without ADR;the monitoring times of ADR patients with blood concentration＞150 ng/mL was significantly higher than those without ADR,with statistical significance(P＜0.05). There was no statistical significance in the incidence of ADR between effective group and ineffective group (P＞0.05). Among effective group,there was no statistically significance in average blood concentration between ADR patients and patients without ADR(P＞0.05);the monitoring times of ADR patients with blood concentration＞150 ng/mL was significantly higher than patients without ADR,with statistical significance(P＜0.05). With the increase of monitoring times,the incidence of ADR decreased gradually. There was no statistical significance in the incidence of ADR among patients who were monitored for different times (P＞0.05). CONCLUSIONS:The pharmacokinetics of CsA varies in different patients and many factors affect its blood concentration. The changes of blood concentration affect the efficacy and safety of CsA. It is difficult to determine the dosage of CsA based on experience in the treatment of NS with CsA. Great importance should be attached to blood concentration monitoring of CsA and the implementation of individualized dosage regimen based monitoring results so as to improve therapeutic efficacy and reduce the occurrence of ADR.

Objective: To explore the effect and security of minimally invasive surfactant therapy (MIST) in treatment of preterm infants with neonatal respiratory distress syndrome (NRDS). Methods: A total of 48 pretrm infants with gestational ages between 30-36 weeks diagnosed with NRDS in Guangzhou Women and Children′s Medical Center from January 2017 to January 2018 were randomly divided into MIST group (23 cases) and intubation-surfactant-extubation+ continuous positive airway pressure ventilation (INSURE) group (25 cases) by adopting random number table method.The patients in MIST group were put on nasal continuous positive airway pressure (nCPAP) and a thin vascular catheter was inserted through the vocal cords under direct vision with direct laryngoscope then infused pulmonary surfactant(PS) into the lung; the patients in INSURE group were endotracheally intubated and infused with PS into the lung through endotracheal tube with positive airway pressure, then extubated and put on nCPAP again.The incidences of adverse reactions and various complications related to the 2 groups were observed. Results: There were no significant differences between 2 groups in oxygen saturation decrease(26.1% vs.36.0%), bradycardia (13.0% vs.24.0%) and reuse PS (8.7% vs.4.0%) (all P>0.05). There were no significant differences between 2 groups in noninvasive ventilation time [8 d (5.5-12.5 d) vs.7 d(5.0-14.0 d)], total oxygen intake time [12 d(7.0-26.5 d) vs.10 d(10.0-23.0 d)] and length of hospital stay [(34.22±16.06) d vs.(30.88±14.35) d] (all P>0.05). There was no death or intraventricular hemorrhage in both groups, and there were no significant differences between 2 groups in the incidences of pneumothorax (0 vs.4.0%), bronchopulmonary dysplasia (21.7% vs.16.0%), retinopathy of prematurity (21.7% vs.12.0%) and necrotizing enterocolitis (21.7% vs.12.0%) (all P>0.05). Conclusions MIST technique is a safe and effective method to administrate surfactant in preterm infants with NRDS.In the NRDS patients who do not need intubation and mechanical ventilation, MIST technique can be used to administrate PS.

OBJECTIVE:To investigate the utilization of the most used splitting drugs in the inpatients of our hospital,and to promote rational use of splitting drugs. METHODS:The medical orders of oral tablets in the inpatients of our hospital in Jan. 2016 were analyzed statistically in respects of consumption quantity,classification dosage,department dosage and the proportion of scored tablets. RESULTS & CONCLUSIONS:There were 217389 medical orders of tablets in the inpatients of our hospital in Jan. 2016. There were 12792 medical orders of splitting drugs,with utilization rate of 5.88%. The most used splitting tablet were car-diovascular drugs and drug for nervous system,accounting for 53.31% and 20.72% of total. The splitting tablets were mostly used in respiratory and critical care medicine department. Top 10 departments in the list of the number of splitting drug medical orders prescribed 8993 splitting drug medical orders,accounted for 70.30% of total. Top 20 drugs in the list of the number of splitting drugs were involved in 8971 medical orders,accounting for 70.13%of total;there were 14 kinds of scored drugs and 7506 medi-cal orders of splitting scored drugs,accounting for 83.67% of top 20 medical orders of splitting drugs. Among splitting drugs,49 types had scored-line,which were prescribed in 9265 medical orders of splitting drug,accounting for 72.43% of all medical or-ders of splitting drug. Lacking of information in most package inserts about the tablet can or can not split,it is suggested to note this information in package inserts by pharmaceutical enterprises. For commonly used splitting drugs without scored-line,it is pro-posed to produce small-size drugs or add scored-line.
