Résumé
Cyclosporine A, a cyclic polypeptide, exhibits potent immunosuppressive activity and exerts its effects through various mechanisms including immunosuppression, anti-inflammatory, inhibition of apoptosis, promotion of epithelial healing and goblet cell function recovery, enhancement of tear secretion, and close association with ocular surface disease repair. Owing to its significant efficacy, inhibition of disease recurrence and few side effects, the clinical application of cyclosporine A in the management of ocular surface diseases, including dry eye, corneal graft rejection following penetrating keratoplasty, vernal keratoconjunctivitis, noninfective keratitis and herpes simplex virus keratitis, has witnessed a substantial rise in recent years. Nevertheless, variations exist in the management of ocular surface inflammatory diseases when utilizing distinct concentrations and dosage forms of cyclosporine A. Therefore, the paper provides an overview of impacts of cyclosporine A on ocular surface diseases.

ObjectiveTo construct a quantitative prediction model of three indicators(moisture absorption rate, film thickness and coating weight gain) during the coating process of Vitamin C Yinqiao tablets(VCYT) by near-infrared spectroscopy(NIRS), and to realize the endpoint judgment. MethodReal-time NIRS data of 4 batches of VCYT during the coating process were collected by diffuse reflection method. The coating method employed was the rolling coating method, and the samples were obtained at the spray stage from the coater's sampling port every 10 minutes, and 57 batches of samples(about 1 800 tablets) were collected at various coating times, the tablets were embedded in molten paraffin, cut longitudinally, and observed by stereomicroscope. The film thickness, with a target value of 38 μm, was then measured using Motic Images Advanced 3.2 software. Furthermore, the mositure absorption rate of samples, aiming for a target value of 3%, was determined in accordance with guiding principles for drug hygroscopicity testing in the 2020 edition of Chinese Pharmacopoeia, and 3 samples were randomly selected from each batch(10 tablets per batch), and the coating weight gain was calculated(target value of 4%). Partial least squares regression(PLSR) was used to construct a quantitative model of the 3 coating indicators, and the predicted values of the coating indicators were smoothed using the moving average method and used to determine the coating endpoints. ResultThe prediction determination coefficients(Rp2) for moisture absorption rate, film thickness and coating weight gain were 0.933 4, 0.932 6 and 0.965 9, the root mean square errors of prediction(RMSEP) were 0.163 5%, 1.870 9 μm and 0.240 3%, the relative percent deviations(RPD) were 3.711 0, 2.760 7 and 5.415 8, respectively. The results of the external validation set demonstrated that the real-time predicted values obtained by the models exhibited the same trend as the measured values, and the coating endpoint could be accurately predicted(with a prediction error of less than 7.32 min and a relative error of less than 5.63%). ConclusionThe established NIRS model exhibits excellent predictive performance and can be used for quality control of VCYT during the coating process.

Objective To analyze the clinical characteristics and regularity of aristolochic acid nephropathy (AAN) induced by drugs containing aristolochic acid. Methods The clinical data of 111 patients with AAN induced by aristolochic acid were reviewed. The clinical features, medication and treatment of AAN were analyzed. Results Among 111 patients, there were more females than males (2.58∶1), 101 cases (90.99%) were over 50 years old; the mean age was (63.70±11.67) years old;the average duration of medication was (8.08±6.94) years. The drugs involved were Guanxinsuhe pill and Longdanxiegan pill in 106 cases (95.50%). Serum creatinine increased in 108 cases, urea nitrogen increased in 106 cases and hemoglobin decreased in 103 cases, most of which were hypogravity urine, mild to moderate proteinuria and occult blood. Ultrasonic examination revealed that the kidneys were damaged to varying degrees. Pathological biopsy of kidney showed renal tubular damage. Most patients had an insidious onset and varying degrees of progression, which were not proportional to the age and the duration of taking the medicine. In clinical, the renal function was progressively damaged, most of which were irreversible and with a poor prognosis. Conclusion Patients with renal impairment differed greatly individually, and the renal damage was not paralleled with the medication duration and dose of drugs containing aristolochic acid.AAN progressed rapidly, and the disease still progressed even after stopping taking drugs containing aristolochic acid. Strengthening pharmacovigilance, implementing early diagnosis and effective intervention could help to reduce the occurrence of AAN and attenuate its development.

Résumé
BACKGROUND:Tendinopathy is a musculoskeletal disorder characterized by pain and decreased mobility,with pathological changes of disturbed collagen and hyperplasia of the vasculature.Tendinopathy tends to occur in athletes,physical workers,and the elderly.One of the mechanisms of tendinopathy is the"failed healing response",and part of what causes the failed healing response is the erroneous differentiation of tendon stem/progenitor cells. OBJECTIVE:By reviewing the relevant literature,we introduce the characteristics of tendon stem/progenitor cells,summarize the factors that affect the differentiation of tendon stem/progenitor cells to tendon cells and those that lead to mis-differentiation of tendon stem/progenitor cells(differentiation to adipocytes,osteocytes and chondrocytes),and also describe the limitations of tendon stem/progenitor cells in clinical applications. METHODS:PubMed and Web of Science databases were searched for the terms"tendon stem/progenitor cells,tendinopathy,tendon injury,differentiation".The relevant literature was screened by reading and 109 articles were included for the analysis of the results. RESULTS AND CONCLUSION:(1)Tendon stem/progenitor cells are a type of stem cells that can spontaneously differentiate into tendons and have the ability to self-renew,clone,and multi-differentiate.Various external conditions acting on tendon stem/progenitor cells can lead them to differentiate in diverse directions.The specific factors that regulate the fate of tendon stem/progenitor cells are not known with certainty.When stem cell renewal and differentiation in tendons becomes abnormal,it can lead to failure of tendon healing and consequently to tendinopathy.(2)Aging,changes in extracellular matrix composition,excessive mechanical stimulation,prostaglandin E2 and interleukin-6 as well as interleukin-10 and some systemic diseases may be important in regulating the mis-differentiation of tendon stem/progenitor cells.(3)Possible favorable factors that promote the differentiation of tendon stem/progenitor cells to tenocytes are:some growth factors and cytokines,moderate mechanical stimulation and topography of the extracellular matrix,low oxygen tension,drugs,and several transcriptional genes and proteins.(4)The most desirable therapeutic tools are the regulation of endogenous tendon stem/progenitor cells or the stimulation of endogenous tendon stem/progenitor cell proliferation and differentiation by exogenous tendon stem/progenitor cells.(5)Understanding the factors that regulate mis-differentiation of tendon stem/progenitor cells may provide insight into the pathogenesis of tendinopathy and identify therapeutic targets.Elaborating on the induction of tendon stem/progenitor cell differentiation into tendons could facilitate their use in tissue engineering.

Background Affected by concentration, composition, and population tolerance of air pollutants, the relationship between air pollutants and population health has regional differences. There is still a research gap in Guiyang. Objective To explore the short-term effects of air pollutant concentrations in low-pollution areas on the outpatient volume of respiratory diseases. Methods Spearman correlation analysis was used to evaluate the correlation between air pollutants, meteorological factors, and respiratory outpatient volume from January 1, 2013 to December 31, 2020 in Guiyang City. A single pollutant distribution lag nonlinear model and a multi-pollutant interaction model were established based on Poisson distribution. A three-dimensional diagram was drawn to display the relationship between air pollutants and respiratory outpatient volume. Quantitative analysis was conducted on the attribution risk and lag effect of air pollutant concentration on outpatient volume of respiratory diseases in Guiyang City. Results The results of the single pollutant model showed that fine particulate matter (PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), and sulfur dioxide (SO2) elevated the outpatient volume of respiratory diseases. The maximum relative risk (RR) and 95%CI values of PM2.5, NO2,CO, and SO2 appeared on Day 2, 0, 5, and 6, respectively, which were 1.019 (1.015, 1.023), 1.146 (1.122, 1.171), 1.129 (1.116, 1.143), and 1.046(1.040, 1.052), respectively. For every quartile concentration increment of PM2.5, NO2, CO, or SO2, the outpatient volume of respiratory diseases increased by 0.943% (0.111%, 1.782%), 4.050% (3.573%, 4.529%), 0.595% (0.317%, 0.874%), or 0.667% (0.235%, 1.100%), respectively. The maximum RR (95%CI) of O3 was 1.015 (1.007, 1.023) and appeared on Day 0. The results of multi-pollutant model showed that PM2.5, NO2, CO, SO2, and O3 all elevated the outpatient volume of respiratory diseases. The maximum RR values of PM2.5, NO2, CO, SO2 and O3 appeared on Day 14, 0, 5, 7 and 0, respectively, which were 1.027 (1.021, 1.034), 1.213 (1.179, 1.248), 1.059 (1.043, 1.074), 1.016 (1.005, 1.026), and 1.024 (1.015, 1.033), respectively. Compared with the single pollutant model, the RR values of PM2.5, NO2, and O3 on the outpatient volume of respiratory diseases in the multi-pollutant model showed an upward trend, while the RR values of CO and SO2 in the multi-pollutant model showed a downward trend. Conclusion The impact of low concentrations of PM2.5, NO2, CO, and SO2 on human health cannot be ignored.

Purpose@#We aimed to analyze the optimal timing of enteral nutrition (EN) in the treatment of sepsis and its effect on sepsis-associated acute kidney injury (SA-AKI.) Materials and Methods: The MIMIC-III database was employed to identify patients with sepsis who had received EN. With AKI as the primary outcome variable, receiver operating characteristic (ROC) curves were utilized to calculate the optimal cut-off time of early EN (EEN). Propensity score matching (PSM) was employed to control confounding effects. Logistic regressions and propensity score-based inverse probability of treatment weighting were utilized to assess the robustness of our findings. Comparisons within the EEN group were performed. @*Results@#2364 patients were included in our study. With 53 hours after intensive care units (ICU) admission as the cut-off time of EEN according to the ROC curve, 1212 patients were assigned to the EEN group and the other 1152 to the delayed EN group. The risk of SA-AKI was reduced in the EEN group (odds ratio 0.319, 95% confidence interval 0.245–0.413, p<0.001). The EEN patients received fewer volumes (mL) of intravenous fluid (IVF) during their ICU stay (3750 mL vs. 5513.23 mL, p<0.001). The mediating effect of IVF was significant (p<0.001 for the average causal mediation effect). No significant differences were found within the EEN group (0–48 hours vs. 48–53 hours), except that patients initiating EN within 48 hours spent fewer days in ICU and hospital. @*Conclusion@#EEN is associated with decreased risk of SA-AKI, and this beneficial effect may be proportionally mediated by IVF volume.

Objective: To explore the related factors of negative conversion time (NCT) of nucleic acid in children with COVID-19. Methods: A retrospective cohort study was conducted. A total of 225 children who were diagnosed with COVID-19 and admitted to Changxing Branch of Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from April 3rd to May 31st 2022 were enrolled in the study. The infection age, gender, viral load, basic disease, clinical symptoms and information of accompanying caregivers were retrospectively analyzed. According to age, the children were divided into<3 years of age group and 3-<18 years of age group. According to the viral nucleic acid test results, the children were divided into positive accompanying caregiver group and negative accompanying caregiver group. Comparisons between groups were performed using Mann-Whitney U test or Chi-square test. Multivariate Logistic regression analysis was used to analyze the related factors of NCT of nucleic acid in children with COVID-19. Results: Among the 225 patients (120 boys and 105 girls) of age 2.8 (1.3, 6.2) years, 119 children <3 years and 106 children 3-<18 years of age, 19 cases were diagnosed with moderate COVID-19, and the other 206 cases were diagnosed with mild COVID-19. There were 141 patients in the positive accompanying caregiver group and 84 patients in the negative accompanying caregiver group.Patients 3-<18 years of age had a shorter NCT (5 (3, 7) vs.7 (4, 9) d, Z=-4.17, P<0.001) compared with patients <3 years of age. Patients in the negative accompanying caregiver group had a shorter NCT (5 (3, 7) vs.6 (4, 9) d,Z=-2.89,P=0.004) compared with patients in the positive accompanying caregiver group. Multivariate Logistic regression analysis showed that anorexia was associated with NCT of nucleic acid (OR=3.74,95%CI 1.69-8.31, P=0.001). Conclusion: Accompanying caregiver with positive nucleic acid test may prolong NCT of nucleic acid, and decreased appetite may be associated with prolonged NCT of nucleic acid in children with COVID-19.

In observational studies, herbal prescriptions are usually studied in the form of "similar prescriptions". At present, the classification of prescriptions is mainly based on clinical experience judgment, but there are some problems in manual judgment, such as lack of unified criteria, labor consumption, and difficulty in verification. In the construction of a database of integrated traditional Chinese and western medicine for the treatment of coronavirus disease 2019(COVID-19), our research group tried to classify real-world herbal prescriptions using a similarity matching algorithm. The main steps include 78 target prescriptions are determined in advance; four levels of importance labeling shall be carried out for the drugs of each target prescription; the combination, format conversion, and standardization of drug names of the prescriptions to be identified in the herbal medicine database; calculate the similarity between the prescriptions to be identified and each target prescription one by one; prescription discrimination is performed based on the preset criteria; remove the name of the prescriptions with "large prescriptions cover the small". Through the similarity matching algorithm, 87.49% of the real prescriptions in the herbal medicine database of this study can be identified, which preliminarily proves that this method can complete the classification of herbal prescriptions. However, this method does not consider the influence of herbal dosage on the results, and there is no recognized standard for the weight of drug importance and criteria, so there are some limitations, which need to be further explored and improved in future research.

Morphine is a frequently used analgesic that activates the mu-opioid receptor(MOR),which has prominent side effects of tolerance.Although the inefficiency of morphine in inducing the endocytosis of MOR underlies the development of morphine tolerance,currently,there is no effective therapy to treat morphine tolerance.In the current study,we aimed to develop a monoclonal antibody(mAb)precisely targeting MOR and to determine its therapeutic efficacy on morphine tolerance and the underlying molecular mechanisms.We successfully prepared a mAb targeting MOR,named 3A5C7,by hybridoma technique using a strategy of deoxyribonucleic acid immunization combined with cell immunization,and identified it as an immunoglobulin G mAb with high specificity and affinity for MOR and binding ability to antigens with spatial conformation.Treatment of two cell lines,HEK293T and SH-SY5Y,with 3A5C7 enhanced morphine-induced MOR endocytosis via a G protein-coupled receptor kinase 2(GRK2)/β-arrestin2-dependent mechanism,as demonstrated by immunofluorescence staining,flow cytometry,Western blotting,coimmunoprecipitation,and small interfering ribonucleic acid(siRNA)-based knock-down.This mAb also allowed MOR recycling from cytoplasm to plasma membrane and attenuated morphine-induced phosphorylation of MOR.We established an in vitro morphine tolerance model using differentiated SH-SY5Y cells induced by retinoic acid.Western blot,enzyme-linked immunosorbent assays,and siRNA-based knockdown revealed that 3A5C7 mAb diminished hyperactivation of adenylate cyclase,the in vitro biomarker of morphine tolerance,via the GRK2/β-arrestin2 pathway.Furthermore,in vivo hotplate test demonstrated that chronic intrathecal administration of 3A5C7 significantly alle-viated morphine tolerance in mice,and withdrawal jumping test revealed that both chronic and acute 3A5C7 intrathecal administration attenuated morphine dependence.Finally,intrathecal electroporation of silencing short hairpin RNA illustrated that the in vivo anti-tolerance and anti-dependence efficacy of 3A5C7 was mediated by enhanced morphine-induced MOR endocytosis via GRK2/β-arrestin2 pathway.Collectively,our study provided a therapeutic mAb,3A5C7,targeting MOR to treat morphine tolerance,mediated by enhancing morphine-induced MOR endocytosis.The mAb 3A5C7 demonstrates promising translational value to treat clinical morphine tolerance.

Objective:To analyze the clinical knowledge and training needs of general practitioners from subjective perception and objective assessment, and to analyze their relationship.Methods:A survey was conducted among general practitioners from community health service centers in Shanghai Changning district from September to December 2020. Based on the general practitioner competency indicator system designed by the project team, 17 clinical knowledge competency evaluation indicators were developed through expert consultation, and used for subjective perception and objective assessment of clinical knowledge and learning needs among general practitioners. The influencing factors of objective assessment scores were analyzed, and the relationship between subjective perception and objective assessment scores was analyzed using the four quadrant method.Results:A total of 136 general practitioners participated in the study with the mean age of (39.25±5.90) years, most of whom were attending physician (67.65%, 92/136) and had undergraduate education (88.20%, 122/136). The average daily application frequency score was (1.55±0.21), and the training needs score was (1.65±0.09) for 17 clinical knowledge items; the average objective evaluation score was (74.21±14.0) points. The older the age ( OR=1.25, 95% CI:1.14-1.37), the higher the educational level ( OR=2.11, 95% CI:1.57-2.83), and the longer the working years ( OR=1.16, 95% CI:1.04-1.30) were significantly correlated with the higher objective evaluation scores (all P<0.05). The objective evaluation scores of endocrine diseases such as diabetes, cerebrovascular diseases and respiratory diseases are the highest, and the daily application frequency and learning needs are high (the first quadrant); The objective evaluation scores of common orthopedic diseases, common psychological diseases, and planned immunity indicators were relatively low, but their daily application frequency and learning needs were relatively high (second quadrant). The objective evaluation scores of indicators such as common malignant tumors, common dermatology diseases and health problems, and common ENT diseases were low, and the daily application frequency and learning needs were also low (the third quadrant). The objective evaluation scores of indicators such as hospice and palliative care are relatively high, but their daily application frequency and training needs are relatively low (listed in the fourth quadrant). Conclusions:The clinical knowledge levels of general practitioners are correlated with age, education level, and years of practice. There is a certain overlap between the objective evaluation results of clinical knowledge and the frequency of knowledge usage and training needs of general practitioners, and a targeted training mechanism should be established.

The Cronbach′s α of the questionnaires was 0.891 and the KMO was 0.844. The positive coefficients for 2 rounds of expert consultation were 100%; the familiarity level of experts was 0.86 and authority level was 0.89 in the first round consultation, and those were 0.84 and 0.90 in the second round consultation. After 2 rounds of consultation, the coordination coefficient of expert opinions in the knowledge and skill dimensions was>0.5, and that in the management dimension and overall evaluation system was>0.3. After discussion 2 indicators were deleted in the first round of consultation. The finally constructed family doctor post competency evaluation scale included 3 dimensions, 8 secondary indicators and 61 tertiary indicators. Conclusion:Through the Delphi consultation, we have successfully constructed an evaluation scale for post competence of family doctors based on the three dimensions of knowledge, skills and management.
Résumé
ObjectiveTo determine the difference of serum neutralizing antibody levels in healthy persons following the vaccination of inactivated SARS-CoV-2 vaccines. MethodsHealth care workers that received inactivated SARS-CoV-2 vaccines were enrolled in Sichuan provincial people's hospital from January to December 2021. All participants were classified into four groups according to the number and time of vaccination, which were groups of 28 days after the second dose, 180 days after the second dose, 28 days after the third dose and 150 days after the third dose. Serum neutralizing antibody was quantitatively detected by chemiluminescence method. Furthermore, the serum neutralizing antibody levels were compared within and between groups by gender, age and body mass index(BMI). ResultsA total of 349 participants were enrolled in this study, including 113 males and 236 females. The positive rates of neutralizing antibody in the groups of 28 days after the second dose, 180 days after the second dose, 28 days after the third dose and 150 days after the third dose were 74.0%, 25.7%, 100.0% and 100.0%, respectively. In the four groups, neutralizing antibody levels were 10.38 (5.76, 24.00) AU·mL-1, 4.18 (3.00, 6.18) AU·mL-1, 41.18 (25.80, 116.21) AU·mL-1 and 33.33 (18.09, 69.12) AU·mL-1, respectively. The positive rate of neutralizing antibody significantly differed across the groups (P<0.001). Furthermore, neutralizing antibody level in the third dose groups were significantly higher than that in the second dose groups (P<0.001). Neutralization antibody level in young people (<45 years old) was significantly higher than that in middle-aged and elderly people (≥45 years old) in the groups of 180 days after the second dose and 28 days after the third dose (P<0.05). Additionally, neutralization antibody level in normal weight participants was significantly higher than that in overweight and obese participants in the group of 28 days after the second dose (P<0.05). However, no significant difference was found in all groups by gender (P>0.05). ConclusionCompared with two doses of inactivated SARS-CoV-2 vaccine, three doses can significantly induce higher neutralizing antibody and stronger immune protection. Age and BMI have certain effect on the neutralizing antibody.
