It is recommended to strengthen the publicity and education on noise protection and take protective measures to reduce the occurrence of occupational noise injury.

Formulation and technology of oxymatrine-astragaloside IV coloaded liposomes based on quality by design / 药学学报

To optimize the formulation and technology of oxymatrine-astragaloside IV coloaded liposomes (Om-As-Lip) based on quality by design (QbD) principles, and further to verify the feasibility of its amplification process, Om-As-Lip was prepared by ethanol injection combined with pH gradient method. The critical material attributions of Om-As-Lip were evaluated by dual-risk analysis tools and Plackett-Burman design (PBD). The formulation of Om-As-Lip was further optimized with the Box-Behnken design (BBD). The design space was also established based on the contour plots of BBD. In order to further investigate the amplification process of Om-As-Lip, the critical process parameters of high-pressure homogenization (HPH) were optimized by single-factor test, and the quality of the final product was also evaluated. The results of risk analysis and PBD confirmed that the astragaloside concentration, cholesterol concentration, and phospholipid ratio (HSPC∶SPC) were the ctitical material attributes. The model established by BBD had a good predictability, and the optimized mass ratio of As to phospholipids was 1∶40, cholesterol to phospholipids was 1∶10, HSPC to SPC was 51∶9. The design space of Om-As-Lip was as follows: the ratio of cholesterol to phospholipids was 1∶12-1∶5 and HSPC to SPC was 1∶7-17∶3. The optimized high-pressure homogenization pressure was 600 bar, temperature was 4 ℃, and cycle times was 6 times for HPH-Om-As-Lip. The quality of Om-As-Lip prepared based on the QbD concept can meet the expected CQAs, and the formulation and technology established can provide a reliable experimental basis for its future development and applications.

Evaluation of GRADE Clinical Research Evidence of Chinese Patent Medicine Combined with Western Medicine in Treatment of Hypertension with Dyslipidemia / 中国实验方剂学杂志

ObjectiveTo evaluate the effect of antihypertensive and lipid-regulating Chinese patent medicine combined with conventional Western medicine in the treatment of hypertension with dyslipidemia. To carry out the evidence synthesis of clinical research and provide evidence-based evidence support for clinical decision-making. MethodThe databases including China National Knowledge Infrastructure （CNKI），Wanfang Data Knowledge Service Platform （WF），VIP，SinoMed，Embase，PubMed，Web of Science （WOS），and the Cochrane Library were searched for randomized controlled trials （RCT） of all listed Chinese patent medicines in the treatment of hypertension with dyslipidemia from the establishment of the databases to April 15，2023. The literature was screened and extracted，and the risk of bias tool 2.0 （RoB2） was used to assess the quality and risk of bias of the methodology. Revman 5.4.1 software was used to analyze the outcome indicators. Grading of Recommendations Assessment，Development and Evaluation （GRADE） was applied to assess the quality of evidence formed by clinical research data. The inclusion and recommendation of Chinese patent medicines in the National Drug Catalogue for Basic Medical Insurance，Work-related Injury Insurance and Maternity Insurance （2022） and domestic guidelines and consensus were searched to form a bubble chart. ResultA total of 15 studies were included. The evaluation of the methodological quality of each study showed that the risk of bias stemmed from the lack of blinding and allocation concealment，and low sample size. The comprehensive analysis of clinical studies showed that Dengzhan Shengmai capsules combined with rosuvastatin and amlodipine besylate，Yindan Xinnaotong capsules combined with simvastatin and levamlodipine tablets，Xiaoshuan Tongluo capsules combined with nifedipine controlled release tablets and pravastatin sodium tablets，Xinshubao capsules combined with atorvastatin calcium tablets and irbesartan，Wenyading capsules combined with enalapril，and Jiangzhining tablets combined with conventional Western medicines were all superior to conventional Western medicines used in the control group in improving systolic blood pressure （SBP），diastolic blood pressure （DBP），cholesterol （TC），triglyceride （TG），low density lipoprotein cholesterol （LDL-C），and high density lipoprotein cholesterol （HDL-C）. There was no significant difference in the incidence of adverse reactions between the two groups. The GRADE evaluation of the main outcome indicators showed that the evidence quality of SBP and incidence of adverse reactions was graded as B，that of DBP as C，and that of total TC，TG，LDL-C，and HDL-C as D. The evaluation of Chinese patent medicines covered by medical insurance and recommended by guidelines and consensus showed that Yindan Xinnaotong soft capsules，Dengzhan Shengmai capsules and Xiaoshuan Tongluo capsules belonged to class B drugs of medical insurance，and were recommended for 7，6 and 3 times in the guidelines and consensus，respectively. ConclusionCompared with simple medicine treatment，Chinese patent medicine combined with conventional Western medicine has more advantages in improving blood pressure and blood lipid，and shows higher safety. Among them，Yindan Xinnaotong soft capsules，Dengzhan Shengmai capsules and Xiaoshuan Tongluo capsules have stronger clinical applicability and economy. All the trials included in this article adhered to the principle of randomization and reported the outcome measures. However，the quality of evidence in related clinical studies was low. In terms of trial design，large-sample，multi-center，blinded randomized controlled trials based on the consolidated standards of reporting trials （CONSORT） statement are still needed for comprehensive trial designs and reporting，to further improve the GRADE quality evaluation and guideline formulation under the guidance of evidence-based medicine，so as to provide higher quality evidence-based research evidence for clinical decision-making.

Objective@#To explore the prevalence of elevated blood pressure and overweight/obesity and their comorbidities among Tibetan middle school students in Lhasa, and to analyze their association with lifestyle and other factors, so as to provide a basis for the intervention measures targeting elevated blood pressure, overweight and obesity among middle school students in high altitude area.@*Methods@#Using a stratified cluster random sampling method in September 2021, a total of 1 488 Tibetan junior and high students from Lhasa City were investigated with blood pressure measurement, physical examination and questionnaire survey. The influencing factors of elevated blood pressure, overweight and obesity and their comorbidities association were analyzed by multivariate Logistic regression.@*Results@#The prevalence of elevated blood pressure, overweight/obesity and their comorbidities were 17.8%, 17.4% , 5.0% respectively. Multivariate Logistic regression analysis showed that age( OR =0.81), residence, body mass inex(BMI) and gender were the influencing factors of elevated blood pressure; and the risks of elevated blood pressure in female students were higher than male students ( OR =1.89), suburban students were higher than urban students ( OR =8.06), overweight and obesity groups were higher than normal groups ( OR =2.55, 2.87) ( P <0.05). Adjusting for confounding factors such as gender, residence and school, and BMI (only for elevated blood pressure), daily screen time ≥2 h was positively correlated with elevated blood pressure, overweight/obesity and its comorbidities ( OR =1.56, 1.59 , 2.51) ( P <0.05).@*Conclusions@#The prevalence of elevated blood pressure, overweight/obesity are relatively high in Lhasa. Longer screen time is a common factor affecting with elevated blood pressure, overweight/obesity and comorbidities among Tibetan students. Measures should be taken intervene in the lifestyle of Tibetan students, in order to reduce elevated blood pressure and overweight/obesity.

Predictive value of systolic pulmonary artery pressure on autonomic nerve excitation in 186 patients with valvular disease: A prospective study / 中国胸心血管外科临床杂志

@#Objective To explore the predictive value of systolic pulmonary artery pressure (SPAP) on autonomic nerve excitation in patients with valvular disease, so as to provide reference for the formulation of clinical intervention plans. Methods The clinical data of patients with valvular disease who received surgical treatment in the General Hospital of Northern Theater Command from August 28, 2020 to February 3, 2021 were prospectively collected. According to the standard deviation of normal-to-normal R-R intervals (SDNN) of the heart rate variability (HRV) of the long-range dynamic electrocardiogram (ECG) 7 days before the operation, the patients were divided into three groups: a sympathetic dominant (SE) group (SDNN≤50 ms), a balance group (50 ms<SDNN<100 ms) and a parasympathetic dominant (PSE) group (SDNN≥100 ms). The correlation between the changes of echocardiographic indexes and autonomic nerve excitation among the groups and the predictive values were analyzed. Results A total of 186 patients were enrolled, including 108 males and 78 females aged 55.92±11.99 years. There were 26 patients in the SE group, 104 patients in the balance group, and 56 patients in the PSE group. The left anteroposterior diameter (LAD), left ventricular end diastolic inner diameter, ratio of peak E to peak A of mitral valve (Em/Am), left ventricular end diastolic volume, left ventricular end systolic volume and SPAP in the SE group were higher than those in the balance group (P<0.05), while peak A of tricuspid valve (At) and left ventricular ejection fraction (LVEF) were lower than those in the balance group (P<0.05). The LAD and Em/Am in the balance group were significantly higher than those in the PSE group (P<0.05). Multivariate analysis showed that patients in the SE group had lower At (right atrial systolic function declines), lower LVEF and higher SPAP than those in the balance group (P=0.04, 0.04 and 0.00). When HRV increased and parasympathetic nerve was excited in patients with valvular disease, Em/Am decreased (left atrial function and/or left ventricular diastolic function declined) with a normal LAD. Pearson analysis showed that there was a linear negative correlation between SPAP and SDNN, with a coefficient of −0.348, indicating that the higher SPAP, the lower HRV and the more excited sympathetic nerve. Receiver operating characteristic curve showed that when SPAP≥45.50 mm Hg (1 mm Hg=0.133 kPa), the sensitivity and specificity of sympathetic excitation in patients with valvular disease were 84.60% and 63.70%, respectively. Conclusion Parasympathetic excitation is an early manifestation of the disease, often accompanied by decreased left atrial function and/or left ventricular diastolic function. Sympathetic nerve excitation can be accompanied by the increase of SPAP and the decrease of left ventricular and right atrial systolic function. SPAP has a unique predictive value for the prediction of autonomic nerve excitation in patients with valvular disease.

Psychological and organizational factors impacting job satisfaction during the COVID-19 Pandemic: A study on similar exposure groups in Indonesia

Introduction@#The COVID-19 pandemic has impacted technical workers who work more often in the field (e.g., engineering, mechanical, health safety environment (HSE), quality control, and production workers) with increasingly complex workloads and work pressures. Few studies have yet to examine the job satisfaction of such workers using a combination of psychological and organizational factors during difficult times, such as the current COVID-19 pandemic. @*Objective@#This study aims to explain whether psychological and organizational factors affect employee job satisfaction as a result of the COVID-19 pandemic. @*Methods@#This quantitative research uses Partial Least Square-Structural Equation Modeling. A survey with a questionnaire was used to collect data in this study. Using the non-probability sampling technique, data from 103 respondents spread throughout four Similar Exposure Groups (SEGs) in Indonesia were collected. Data analysis in this study used SmartPLS 3.0. @*Results@#Male workers in this study constituted more than 90% of the respondents, the majority with a long working period (more than five years). Worker experience was directly proportional to worker age; most workers were between 41 and 56 years old. The results, with a majority of SEGs from engineering, found that out of five hypotheses (H1–H5), four are accepted while one is rejected. Employee job satisfaction during this pandemic is influenced by the feeling of safety (H1) and work pressure (H3). Work pressure is further influenced by the feeling of safety at work (H2). Moreover, work pressure acts as a mediator on the feeling of safety and job satisfaction (H4). However, job satisfaction is not influenced by management commitment (H5). @*Conclusion@#Management commitment to work safety during pandemic situations must be adjusted, especially regarding policies to ensure the availability of additional standards on health protocols to prevent the spread of COVID-19 in the workplace. In addition, the guarantee that the company is committed to ensuring that workers feel safe will be covered if exposed to COVID-19. Occupational safety and health standards are no longer fully focused on work equipment or facilities. The feeling of safety and work pressure during a pandemic require attention from companies in accordance with their existing limitations and capabilities.

Objective To analyze the correlation between the lung allocation score (LAS) and the risk of early death and complications in patients with idiopathic pulmonary fibrosis (IPF) after lung transplantation. Methods Clinical data of 275 patients with IPF were retrospectively analyzed. The correlation between LAS and the risk of early death in IPF patients after lung transplantation and the correlation between LAS and complications at postoperative 1 year was assessed by univariate and multivariate Cox regression analyses. Results Among 275 recipients, 62, 83, 95 and 108 cases died within postoperative 30, 90, 180 and 365 d, respectively. LAS was correlated with 30-, 90-, 180- and 365-d fatality of IPF patients (all P<0.05), whereas it was not correlated with the incidence of primary graft dysfunction (PGD) and acute kidney injury (AKI) at 365 d after lung transplantation (both P>0.05). Conclusions LAS is correlated with the risk of early death of IPF patients after lung transplantation. While, it is not correlated the incidence of PGD and AKI early after lung transplantation. Special attention should be paid to the effect of comprehensive factors upon PGD and AKI.

Nonsuperotemporal quadrant implantation of the Ahmed glaucoma valve using modified long scleral tunnel technique for intraocular pressure control

ABSTRACT Purpose: As superotemporal implantation of the Ahmed glaucoma valve is not always feasible in cases of refractory glaucoma, this study examined the characteristics and surgical outcomes of cases in which the valve was implanted in a nonsuperotemporal quadrant using a modified long scleral tunnel technique. Methods: This retrospective case-control study included 37 eyes with nonsuperotemporal quadrant--Ahmed glaucoma valve implantation in Group 1 and 69 eyes with superotemporal Ahmed glaucoma valve implantation in Group 2. The demographic characteristics of these groups, surgical outcomes, including complications, further surgical interventions, and surgical success rates were compared. Surgical success was defined as an intraocular pressure not exceeding 21 mmHg, accompanied by a minimum reduction of 20% in intraocular pressure from the baseline without any additional intraocular pressure-lowering procedures, and the absence of light perception loss or phthisis bulbi. Results: Group 1 had significantly higher numbers of eyes with secondary glaucoma and preoperative surgical procedures than Group 2 (p<0.05). Both groups had mean preoperative intraocular pressure values, and mean intraocular pressure values at the last visit of 34.2 and 27.9 months, 35.5 ± 1.5 and 35.8 ± 1.2 mmHg, and 14.5 ± 5 and 14.9 mmHg, respectively. Although both groups had 70.2% and 75.8% as their five-year cumulative probability of success, respectively, the rates of complications, revisional surgery, and additional surgical procedures did not differ significantly (p>0.05). Conclusion: The modified long scleral tunnel technique for Ahmed glaucoma valve implantation in nonsuperotemporal quadrants achieves intraocular pressure control and complication rates comparable to superotemporal implantation.

Age as a predictive factor for reduced intracranial compliance in patients with headache / Idade como fator preditor de complacência intracraniana reduzida em pacientes com cefaleia

Abstract Background Increased intracranial pressure (ICP) consists of a set of signs and symptoms related to changes in intracranial compliance (ICC) and ICP. Objective This study presents a retrospective analysis of patients who underwent non-invasive monitoring of ICC based on complaints of headache, correlating decreased brain compliance and increased intracranial pressure. Methods Noninvasive ICC monitoring was performed using a Brain4care device, which contains a strain gauge and a recorder connected to a mechanical device that touches the scalp surface in the frontoparietal area lateral to the sagittal suture. This tool monitors the ICP by identifying small changes in skull measurements that are caused by pressure variations, i.e., skull deformation is associated with the detection of changes in mean ICP. A clinical evaluation of 32 patients with complaints of headache occurred from the analysis of their medical records. Results Of the 32 patients initially chosen, it was possible to complete the analysis of 18 due to the availability of data in the medical records. From the non-invasive monitoring of the ICC, the following data were collected: time-to-peak, P2/P1 ratio, age, and gender. From the statistical analysis of age and P2/P1 ratio, it was noted that as age increases, ICC tends to decrease regardless of sex (p < 0.05). Conclusion This study concluded that there is a correlation between changes in intracranial compliance and headache complaints in outpatients. There was also a relationship between age and decreased intracranial compliance but without a specific pain pattern.

Resumo Antecedentes O aumento da pressão intracraniana (PIC) consiste em um conjunto de sinais e sintomas relacionados a mudanças na complacência intracraniana (CIC) e na PIC. Objetivo Este estudo apresenta uma análise retrospectiva de pacientes que foram submetidos ao monitoramento não invasivo da CIC com base em queixas de cefaleia, correlacionando a diminuição da complacência cerebral e o aumento da pressão intracraniana. Métodos O monitoramento não invasivo da CIC foi realizado utilizando um dispositivo Brain4Care, que contém um medidor de tensão e um gravador conectado a um dispositivo mecânico que toca a superfície do couro cabeludo na área frontoparietal lateral à sutura sagital. Esta ferramenta monitora a PIC identificando pequenas alterações nas medidas do crânio que são causadas por variações de pressão, ou seja, a deformação do crânio está associada à detecção de alterações na PIC média. Uma avaliação clínica de 32 pacientes com queixas de cefaleia ocorreu a partir da análise de seus prontuários médicos. Resultados Dos 32 pacientes inicialmente escolhidos, foi possível concluir a análise de 18 devido à disponibilidade de dados nos prontuários médicos. A partir do monitoramento não invasivo da CIC, foram coletados os seguintes dados: time-to-peak, relação P2/P1, idade e sexo. Da análise estatística de idade e relação P2/P1, observou-se que à medida em que a idade aumenta, a CIC tende a diminuir independentemente do sexo (p < 0,05). Conclusão Este estudo concluiu que existe uma correlação entre as mudanças na CIC e a queixa de cefaleia em pacientes ambulatoriais. Houve também uma relação entre idade e diminuição da CIC, mas sem um padrão de dor específico.

Use of FGF21 analogs for the treatment of metabolic disorders: a systematic review and meta-analysis

ABSTRACT FGF21 is a hormone produced primarily by the liver with several metabolic functions, such as induction of heat production, control of glucose homeostasis, and regulation of blood lipid levels. Due to these actions, several laboratories have developed FGF21 analogs to treat patients with metabolic disorders such as obesity and diabetes. Here, we performed a systematic review and meta-analysis of randomized controlled trials that used FGF21 analogs and analyzed metabolic outcomes. Our search yielded 236 articles, and we included eight randomized clinical trials in the meta-analysis. The use of FGF21 analogs exhibited no effect on fasting blood glucose, glycated hemoglobin, HOMA index, blood free fatty acids or systolic blood pressure. However, the treatment significantly reduced fasting insulinemia, body weight and total cholesterolemia. None of the included studies were at high risk of bias. The quality of the evidence ranged from moderate to very low, especially due to imprecision and indirection issues. These results indicate that FGF21 analogs can potentially treat metabolic syndrome. However, more clinical trials are needed to increase the quality of evidence and confirm the effects seen thus far.

Intraocular pressure changes under an atmospheric pressure spectrum in a multiplace hyperbaric chamber / Análise de alterações da pressão intraocular (PIO) sob o espectro da pressão atmosférica em uma câmara hiperbárica multi-lugar

ABSTRACT Purpose: To evaluate the influence of atmospheric pressure changes on the behavior of intraocular pressure of healthy military individuals-students and instructors of the National Navy's Diving & Rescue School at the "ARC BOLÍVAR" naval base-during a simulated immersion in the hyperbaric chamber of the Naval Hospital of Cartagena. Methods: A descriptive exploratory study was performed. The intraocular pressure was measured at different atmospheric pressures during 60-min sessions in the hyperbaric chamber while breathing compressed air. The maximum simulated depth was 60 feet. Participants were students and instructors of the Naval Base's Diving and Rescue Department. Results: A total of 48 eyes from 24 divers were studied, of which 22 (91.7%) were male. The mean age of the participants was 30.6 (SD=5.5) years, ranging from 23 to 40. No participant had a history of glaucoma or ocular hypertension. The mean base intraocular pressure at sea level was 14 mmHg, which decreased to 13.1 mmHg (decreased by 1.2 mmHg) at 60 feet deep (p=0.0012). However, during the safety stop at 30 feet, the mean IOP kept decreasing until reaching 11.9 mmHg (p<0.001). By the end of the session, the mean intraocular pressure reached 13.1 mmHg, which is inferior and statistically significant when compared with the intraocular pressure base mean (p=0.012). Conclusions: In healthy individuals, the intraocular pressure decreases when reaching a depth of 60 feet (2.8 absolute atmosphere pressure) and it decreases even more during ascension at 30 feet. Measurements at both points were significantly different when compared with base intraocular pressure. The final intraocular pressure was lower than the baseline intraocular pressure, suggesting a residual and prolonged effect of the atmospheric pressure on intraocular pressure.

RESUMO Objetivo: Avaliar a influência das alterações da pressão atmosférica no comportamento da pressão intraocular de indivíduos militares saudáveis-alunos e instrutores da Escola de Mergulho e Resgate da Marinha Nacional na base naval "ARC BOLÍVAR"-durante uma imersão simulada na câmara hiperbárica do Hospital da Marinha de Cartagena. Métodos: Realizamos um estudo exploratório descritivo. A pressão intraocular foi medida em diferentes pressões atmosféricas durante sessões de 60 minutos na câmara hiperbárica respirando ar comprimido. A profundidade máxima simulada foi de 60 pés. Os participantes eram alunos e instrutores do Departamento de Mergulho e Resgate da Base Naval. Resultados: Quarenta e oito olhos de 24 mergulhadores foram estudados. Vinte e dois participantes (91,7%) eram do sexo masculino. A média de idade dos participantes foi de 30,6 (DP=5,5) anos, variando de 23 a 40. Nenhum participante tinha histórico de glaucoma ou hipertensão ocular. A média de base da pressão intraocular ao nível do mar foi de 14 mmHg, diminuindo para 13,1 mmHg (queda de 1,2 mmHg) a 60 pés de profundidade (p=0,0012). Entretanto, durante a parada de segurança a 30 pés, a pressão intraocular média continuou diminuindo até atingir 11,9 mmHg (p<0,001). Ao final da sessão, a pressão intraocular média atingiu 13,1 mmHg, valor inferior e estatisticamente significativo quando comparada à média de base da pressão intraocular (p=0,012). Conclusões: Em indivíduos saudáveis, a pressão intraocular diminui ao atingir uma profundidade de 60 pés (2,8 de pressão atmosférica absoluta) e diminui ainda mais durante a ascensão a 30 pés. As medidas em ambos os pontos foram significativamente diferentes quando comparadas à pressão intraocular de base. A pressão intraocular final foi menor do que a pressão intraocular de base, sugerindo um efeito residual e prolongado da pressão atmosférica sobre a pressão intraocular.
