ABSTRACT

In July 2023, the National Medical Products Administration issued the Measures for the Administration of Standards for Medicinal Products (hereinafter referred to as the Measures). This article interprets the main content of the Measures, and analyzes its shortcomings as unclear definition of the drug standard code and the goals of drug standard information construction. It is recommended that the national drug regulatory department promptly apply to the standardization authority for the confirmation of the drug standard code “YB” letter, and the drug standard code and numbering rules would be included in the next round of amendments to the Measures. It is necessary to clarify the construction goals of the information system for drug standards at the same time, and build a national drug standard data-sharing platform based on the basic framework of user interface layer, computing processing layer, and data storage layer. Digital drug standards will be free, and access and download services for the public will be provided.

ABSTRACT

Objective:To explore the effect of joint segmentation model of myocardial-fibrotic region based on deep learning in quantitative analysis of myocardial fibrosis in patients with dilated cardiomyopathy(DCM).Methods:The data of 200 patients with confirmed DCM and myocardial fibrosis in the left ventricle detected by cardiac MR-late gadolinium enhancement (CMR-LGE) in Xuzhou Central Hospital from January 2015 to April 2022 were retrospectively analyzed. Using a complete randomized design, the patients were divided into training set ( n=120), validation set ( n=30) and test set ( n=50). The left ventricle myocardium was outlined and the normal myocardial region was selected by radiologists. Fibrotic myocardium was extracted through calculating the threshold with standard deviation (SD) as a reference standard for left ventricle segmentation and fibrosis quantification. The left ventricular myocardium was segmented by convex prior U-Net network. Then the normal myocardial image block was recognized by VGG image classification network, and the fibrosis myocardium was extracted by SD threshold. The myocardial segmentation effect was evaluated using precision, recall, intersection over union (IOU) and Dice coefficient. The consistency of myocardial fibrosis ratio in left ventricle obtained by joint segmentation model and manual extraction was evaluated with intra-class correlation coefficient (ICC). According to the median of fibrosis rate, the samples were divided into mild and severe fibrosis, and the quantitative effect of fibrosis was compared by Mann-Whitney U test. Results:In the test set, the precision of myocardial segmentation was 0.827 (0.799, 0.854), the recall was 0.849 (0.822, 0.876), the IOU was 0.788 (0.760, 0.816), and the Dice coefficient was 0.832 (0.807, 0.857). The consistency of fibrosis ratio between joint segmentation model and manual extraction was high (ICC=0.991, P<0.001). No statistically significant difference was found in the ratio error between mild and severe fibrosis ( P>0.05). Conclusions:The joint segmentation model realizes the automatic calculation of myocardial fibrosis ratio in left ventricle, which is highly consistent with the results of manual extraction. Therefore, it can accurately realize the automatic quantitative analysis of myocardial fibrosis in patients with dilated cardiomyopathy.

ABSTRACT

Objective:To evaluate the value of shear wave elastography (SWE) in skin assessment of Systemic sclerosis (SSc).Methods:A total of 58 SSc patients admitted to Peking University Third Hospital from May 2021 to October 2022 and 41 healthy volunteers were included in the study. Skin shear wave elastography (SWE) was performed at 17 sites defined in modified Rodnan skin score (mRSS) measurement, and shear wave velocity values were recorded to evaluate skin hardness. SPSS 22.0 software was used to analyze the skin hardness of SSc patients and healthy controls, and the correlation between skin hardness of SSc patients and clinical data was analyzed. A logistic regression model was constructed to evaluate the diagnostic efficacy of skin hardness at different sites of SSc patients, and to further select the most practical measurement site.Results:The SWE value of SSc patients was significantly higher than that of healthy control group ( P<0.05). There was a positive correlation between SWE and mRSS in the measurement of bilateral fingers, bilateral dorsal hands, bilateral forearms, fore-chest, abdomen, bilateral thighs, and bilateral dorsal feet. Skin stiffness measured by SWE was significantly correlated with SSc disease activity score (EScSG-DAI), ( r=0.71, P<0.001), disease injury score (SCTC-DI), (P=0.55, P=0.005) and functional score (HAQ-DI), ( r=0.46, P=0.003). Reducing the number of measurement sites to 12 (bilateral fingers, bilateral hands, bilateral forearms, bilateral upper arms, forehead, fore-chest, bilateral dorsum of feet) performs as well as all 17 measurement sites simultaneously in assessing disease activity. Conclusion:SWE is a good evaluation tool to reflect the skin lesions of SSc, which is of great value for the diagnosis and evaluation of the disease. We can further standardize the measurement sites and select the most appropriate evaluation strategy, so as to achieve better clinical application.

ABSTRACT

Objective:To investigate the application value of outcome-based education (OBE) combined with team-based learning (TBL) in the practice teaching of pediatric emergency and critical care nursing.Methods:A total of 84 nursing students who studied in the pediatric intensive care unit (PICU) of The First Affiliated Hospital of Air Force Medical University were selected and divided into control group and observation group. The 41 nursing students in the control group received traditional teaching, and the 43 nursing students in the observation group received OBE+TBL teaching. The two groups were assessed in terms of theoretical knowledge, practical operation ability, clinical thinking ability, and self-learning ability after teaching, and the degrees of satisfaction with teaching and participation in teaching were compared between the two groups. SPSS 22.0 was used for the t-test and the chi-square test. Results:After teaching, the observation group had significantly better theoretical knowledge, practical operation ability, and self-learning ability than the control group ( P<0.05). Compared with the control group, the observation group had significantly higher scores of learning engagement (recognition, behavior, emotion) ( P<0.05) and satisfaction with classroom effect, knowledge mastery, and learning interest ( P<0.05). Conclusion:The application of OBE+TBL teaching in PICU nursing students can effectively improve their self-learning ability and participation and help them to understand PICU nursing priorities and improve their practical operation ability.

ABSTRACT

Objective:To explore risk factors for clinical onset in children with uncontrolled self-limited epilepsy with centrotemporal spikes (SeLECTS) managed by 2 anti-seizure medications (ASMs).Methods:A total of 112 children with SeLECTS who were diagnosed at the Department of Pediatric Neurology of the Third Affiliated Hospital of Zhengzhou University from January 2018 to May 2021 were retrospectively reviewed.All of them were treated with conventional ASMs, and regularly followed up for 1-2 years.Types of therapeutic drugs, clinical seizure control status, presence of new seizure forms, electroencephalogram (EEG) were reviewed at follow-up visits.According to whether the seizures were controlled after the use of no more than 2 ASMs, patients were divided into poor response group (43 cases) and good response group (69 cases), and their clinical data and EEG characteristics were compared.Multivariate Logistic regression analysis was used to explore the risk factors for seizures that were uncontrolled by 2 ASMs. Results:There were significant differences in the age of onset ( χ2=8.919, P=0.003), seizure form ( χ2=4.218, P=0.040), seizure frequency ( Z=-7.664, P<0.001), EEG background slowing ( χ2=10.284, P=0.001), emergence of electrical status epilepticus during slow-wave sleep (ESES)( χ2=11.921, P=0.001), discharge generalization ( χ2=25.377, P<0.001), and presence of epileptic encephalopathy with spike-and-wave activation in sleep (EE-SWAS)( χ2=54.334, P<0.001) between groups.Multivariate Logistic regression analysis showed that seizure frequency ( P<0.001, OR=0.086, 95% CI: 0.022-0.329), discharge generalization ( P=0.006, OR=9.942, 95% CI: 1.918-51.527) and EEG background slowing ( P=0.041, OR=6.648, 95% CI: 1.077-41.038) were the 3 main risk factors associated with poor response to short-term medications of ASMs. Conclusions:Seizures are easily controlled in most SeLECTS patients medicated with ASMs with a favorable prognosis.Seizure frequency, discharge generalization and EEG background slowing are risk factors for the poor response to short-term pharmacotherapy in children with SeLECTS.

ABSTRACT

The formation of learning and memory is regulated by synaptic plasticity in hippocampal neurons. Here we explored how gestational exposure to dexamethasone, a synthetic glucocorticoid commonly used in clinical practice, has lasting effects on offspring's learning and memory. Adult offspring rats of prenatal dexamethasone exposure (PDE) displayed significant impairments in novelty recognition and spatial learning memory, with some phenotypes maintained transgenerationally. PDE impaired synaptic transmission of hippocampal excitatory neurons in offspring of F1 to F3 generations, and abnormalities of neurotransmitters and receptors would impair synaptic plasticity and lead to impaired learning and memory, but these changes failed to carry over to offspring of F5 and F7 generations. Mechanistically, altered hippocampal miR-133a-3p-SIRT1-CDK5-NR2B signaling axis in PDE multigeneration caused inhibition of excitatory synaptic transmission, which might be related to oocyte-specific high expression and transmission of miR-133a-3p. Together, PDE affects hippocampal excitatory synaptic transmission, with lasting consequences across generations, and CDK5 in offspring's peripheral blood might be used as an early-warning marker for fetal-originated learning and memory impairment.

ABSTRACT

Brain size abnormality is correlated with an increased frequency of autism spectrum disorder (ASD) in offspring. Genetic analysis indicates that heterozygous mutations of the WD repeat domain 62 (WDR62) are associated with ASD. However, biological evidence is still lacking. Our study showed that Wdr62 knockout (KO) led to reduced brain size with impaired learning and memory, as well as ASD-like behaviors in mice. Interestingly, Wdr62 Nex-cKO mice (depletion of WDR62 in differentiated neurons) had a largely normal brain size but with aberrant social interactions and repetitive behaviors. WDR62 regulated dendritic spinogenesis and excitatory synaptic transmission in cortical pyramidal neurons. Finally, we revealed that retinoic acid gavages significantly alleviated ASD-like behaviors in mice with WDR62 haploinsufficiency, probably by complementing the expression of ASD and synapse-related genes. Our findings provide a new perspective on the relationship between the microcephaly gene WDR62 and ASD etiology that will benefit clinical diagnosis and intervention of ASD.

ABSTRACT

Medication during pregnancy is widespread, but there are few reports on its fetal safety. Recent studies suggest that medication during pregnancy can affect fetal morphological and functional development through multiple pathways, multiple organs, and multiple targets. Its mechanisms involve direct ways such as oxidative stress, epigenetic modification, and metabolic activation, and it may also be indirectly caused by placental dysfunction. Further studies have found that medication during pregnancy may also indirectly lead to multi-organ developmental programming, functional homeostasis changes, and susceptibility to related diseases in offspring by inducing fetal intrauterine exposure to too high or too low levels of maternal-derived glucocorticoids. The organ developmental toxicity and programming alterations caused by medication during pregnancy may also have gender differences and multi-generational genetic effects mediated by abnormal epigenetic modification. Combined with the latest research results of our laboratory, this paper reviews the latest research progress on the developmental toxicity and functional programming alterations of multiple organs in offspring induced by medication during pregnancy, which can provide a theoretical and experimental basis for rational medication during pregnancy and effective prevention and treatment of drug-related multiple fetal-originated diseases.

ABSTRACT

“Cold-dampness entering ying (营)” is the key to the worsening of cold-dampness epidemic, and is more common in the elderly or critically ill cases of cold-dampness epidemic with pathogen exuberance and healthy qi deficiency. This paper reported a case of critically ill COVID-19 combined with multiple organ dysfunction treated by integrative traditional Chinese and western medicine based on “cold-dampness entering ying” theory. The patient did not have high fever after being infected with SARS-Cov-2, but D-dimer continued to increase, and she developed multiple thrombosis throughout the body and multiple organ dysfunctions such as pulmonary embolism, edema, oliguria, and shock. The patient were with enlarged and dusky tongue, with yellow, thick and greasy coating, and sublingual blood stasis, and thready, rapid and rough pulse. All these were characteristic manifestations of “cold-dampness entering ying”, and was differentiated as cold-dampness stasis. For the treatment, symptomatic and supportive western medicine of improving heart function, anti-infection, relieving asthma, stopping cough and reducing phlegm was given as the basic therapy, and additionally, traditional Chinese medicine to open the constraint and the blocked, save from collapse and restore yang, boost qi and relieve collapse, invigorate blood and drain water was used, usually with Modified Poge Zilong Xuanbai Chengqi Decoction (破格子龙宣白承气汤加减), which was in accordance with the pathogenesis and thus achieving good effect.

ABSTRACT

Objective: To investigate the features of contrast-enhanced ultrasound (CEUS) in hepatic epithelioid hemangioendothelioma (HEHE) in order to improve the preoperative diagnosis rate. Methods: CEUS images of 32 pathologically-proven cases of hepatic epithelioid hemangioendothelioma from January 2004 to August 2021 were collected. Lesions were analyzed to observe the features of enhancement mode, enhancement intensity, and distinct enhancement phases. Results: Among the 32 cases, one had a solitary lesion, 29 had multiple lesions, and two had diffuse-type lesions. Contrast-enhanced ultrasound revealed a total of 42 lesions in 32 cases. In terms of arterial phase enhancement, 18 lesions had overall enhancement, six lesions had uneven dendritic enhancement, 16 lesions had rim-like enhancement, and two lesions had just slight peripheral spot enhancement around the lesions. Among the three cases, there were multiple lesions that had overall enhancement and ring enhancement. In terms of the enhancement phase, 20 lesions showed "fast progression", 20 lesions showed "same progression", and two lesions showed "slow progression". During the late arterial or early portal venous phases with rapid washout, all lesions manifested as hypoechoic. With peaked enhanced intensity, 11 lesions had a lower enhancement intensity than the surrounding normal liver parenchyma; 11 lesions had the same enhancement degree as the surrounding normal liver parenchyma; and 20 lesions had a higher enhancement degree than the surrounding normal liver parenchyma. All 16 ring-enhancing lesions had marked hyperenhancement. In the typical enhancing lesions, four showed hyperenhancement, five showed low enhancement, and nine showed isoenhancement. In the dendrite-enhancing lesions, there were two isoenhancing and four hypoenhancing. Contrast-enhanced ultrasound delineated the boundaries of all lesions more clearly than two-dimensional ultrasound. Conclusion: Contrast-enhanced ultrasound has certain value in the diagnosis of hepatic epithelioid hemangioendothelioma.

ABSTRACT

Objective: To study the incidence of bloodstream infections, pathogen distribution, and antibiotic resistance profile in patients with hematological malignancies. Methods: From January 2018 to December 2021, we retrospectively analyzed the clinical characteristics, pathogen distribution, and antibiotic resistance profiles of patients with malignant hematological diseases and bloodstream infections in the Department of Hematology, Nanfang Hospital, Southern Medical University. Results: A total of 582 incidences of bloodstream infections occurred in 22,717 inpatients. From 2018 to 2021, the incidence rates of bloodstream infections were 2.79%, 2.99%, 2.79%, and 2.02%, respectively. Five hundred ninety-nine types of bacteria were recovered from blood cultures, with 487 (81.3%) gram-negative bacteria, such as Klebsiella pneumonia, Escherichia coli, and Pseudomonas aeruginosa. Eighty-one (13.5%) were gram-positive bacteria, primarily Staphylococcus aureus, Staphylococcus epidermidis, and Enterococcus faecium, whereas the remaining 31 (5.2%) were fungi. Enterobacteriaceae resistance to carbapenems, piperacillin/tazobactam, cefoperazone sodium/sulbactam, and tigecycline were 11.0%, 15.3%, 15.4%, and 3.3%, with a descending trend year on year. Non-fermenters tolerated piperacillin/tazobactam, cefoperazone sodium/sulbactam, and quinolones at 29.6%, 13.3%, and 21.7%, respectively. However, only two gram-positive bacteria isolates were shown to be resistant to glycopeptide antibiotics. Conclusions: Bloodstream pathogens in hematological malignancies were broadly dispersed, most of which were gram-negative bacteria. Antibiotic resistance rates vary greatly between species. Our research serves as a valuable resource for the selection of empirical antibiotics.

ABSTRACT

Objective:To discuss the principle and effect of augmentation rhinoplasty with auricular cartilage and expanded polytetrafluoroethylene.Methods:From January 2018 to January 2020, 161 patients (10 males and 151 females; aged from 19 to 48 years, with an average of 26 years) underwent " auricular cartilage plus expanded polytetrafluoroethylene" augmentation rhinoplasty in Nanfang Hospital of Southern Medical University. The expended polytetrafluoroethylene was carved into a willow leaf shape (I Shape) to fill the nasal dorsum, and the cartilage taking from cymba concha was constructed into an arched bridge shape for the nasal tip shaping. Pre-operative and 1-year post-operative measurements nasal length, nasal height, nasal depth, nasal columella height, nasal tip width, nasofrontal angle, nasolabial angle, survey of satisfaction and complication rate 1-2 years after operation were taken. The statistical analysis of nasal morphological indicators and nasal aesthetic indicators were employed.Results:The nose shape of 161 patients was improved to varying degree. All morphological indicators were improved, and difference was statistically significant ( P<0.05). The nasofrontal angle reached the standard in 90 cases, accounting for 55.9%; The nasolabial angle reached the standard in 143 cases, accounting for 88.8%. 2 cases had prosthesis (ePTFE) deviation and were corrected by surgical repair; 1 case had prosthesis (ePTFE) rejection and was corrected by prosthesis (ePTFE) removal surgery. Conclusions:Corresponding to the anatomical characteristics of the external nose, the prosthesis material is designed and made to correspond to the dorsum shape of the nasal stent. The shape of the alar cartilage, the prefabricated arched bridge shape of the cymba concha cartilage are used to reconstruct the nasal tip, which can effectively elevate the nasal dorsum, improve the protruding degree and rotation degree of the nasal tip, and have good long-term support. The flexibility and activity of the nasal tip are similar to the biological nose.

ABSTRACT

OBJECTIVES@#To study the clinical features of severe meconium aspiration syndrome (MAS) and early predicting factors for the development of severe MAS in neonates with meconium-stained amniotic fluid (MSAF).@*METHODS@#A total of 295 neonates who were hospitalized due to Ⅲ° MSAF from January 2018 to December 2019 were enrolled as subjects. The neonates were classified to a non-MAS group (n=199), a mild/moderate MAS group (n=77), and a severe MAS group (n=19). A retrospective analysis was performed for general clinical data, blood gas parameters, infection indicators, and perinatal clinical data of the mother. The respiratory support regimens after birth were compared among the three groups. The receiver operating characteristic (ROC) curve and multivariate logistic regression analysis were used to investigate predicting factors for the development of severe MAS in neonates with MSAF.@*RESULTS@#Among the 295 neonates with MSAF, 32.5% (96/295) experienced MAS, among whom 20% (19/96) had severe MAS. Compared with the mild/moderate MAS group and the non-MAS group, the severe MAS group had a significantly lower 5-minute Apgar score (P<0.05) and a significantly higher blood lactate level in the umbilical artery (P<0.05). Compared with the non-MAS group, the severe MAS group had a significantly higher level of interleukin-6 (IL-6) in peripheral blood at 1 hour after birth (P<0.017). In the severe MAS group, 79% (15/19) of the neonates were born inactive, among whom 13 underwent meconium suctioning, and 100% of the neonates started to receive mechanical ventilation within 24 hours. Peripheral blood IL-6 >39.02 pg/mL and white blood cell count (WBC) >30.345×109/L at 1 hour after birth were early predicting indicators for severe MAS in neonates with MSAF (P<0.05).@*CONCLUSIONS@#Meconium suctioning cannot completely prevent the onset of severe MAS in neonates with MSAF. The neonates with severe MAS may develop severe respiratory distress and require mechanical ventilation early after birth. Close monitoring of blood lactate in the umbilical artery and peripheral blood IL-6 and WBC at 1 hour after birth may help with early prediction of the development and severity of MAS.

ABSTRACT

Objective To look for a tissue paraffin embedding method that can replace xylene transparent agent. Methods The mixture of N-butanol and turpentine was used to replace the role of anhydrous ethanol and xylene in the process of conventional paraffin embedding. The brain, kidney, stomach, liver and duodenum of multiple cerebral infarction model rats were embedded in paraffin. Finally, the new dehydration procedure was evaluated according to the effect of paraffin section, HE staining and immunohistochemical result . Results The mixture of N-butanol and turpentine could replace not only the dehydration effect of anhydrous ethanol but also the transparency effect of xylene in the conventional paraffin embedding process. The tissue sections treated with the mixture of N-butanol and turpentine were smooth, and the tissue did not become brittle or hard; After HE staining, the nucleus and cytoplasm of the new dehydrated tissue were distinct, and the chromaticity, color and transparency of the tissue were not different from those of the conventional dehydration procedure; Immunohistochemical staining was performed on different tissues of rats, and the comparison result were no different from conventional embedded tissue immunohistochemical staining. Conclusion N-butanol combined with turpentine for tissue dehydration can not only avoid the toxic effect of xylene on human, but also reduce the tissue damage caused by excessive dehydration of anhydrous alcohol.

ABSTRACT

AIM: To observe the effect of PCSK9 inhibitors on blood lipid levels and common inflammatory factors in patients with coronary heart disease. METHODS: The clinical data of 201 patients with coronary heart disease who were admitted to the Department of Cardiology of Shanghai East Hospital from April 2020 to June 2021 were retrospectively analyzed. The patients were divided into PCSK9 inhibitor treatment group (101 cases: statin + PCSK9 inhibitor) and control group (100 cases: statin treatment only) according to their medication status. Blood lipids, blood routine, CRP and FIB were re-examined after 1 month of treatment. The changes of blood lipids and inflammatory factors before and after treatment were compared. RESULTS: Before treatment, there was no significant difference in blood lipids, blood routine, CRP and FIB between the two groups (P> 0.05). The levels of sdLDL and Lp(a) were significantly decreased (P< 0.05); the levels of WBC, CRP, N and FIB were significantly decreased (P< 0.05). Compared with the control group, the levels of TC, HDL, LDL-C, CRP and FIB in the PCSK9 inhibitor group were significantly changed (P< 0.05), and the results were statistically significant. CONCLUSION: PCSK9 inhibitors can not only reduce LDL-C levels, but also reduce Lp(a) levels. PCSK9 inhibitors can reduce CRP and FIB levels, suggesting that it can partially improve inflammation in peripheral blood in patients with coronary heart disease.
