Risk factors of extrauterine growth retardation in very preterm infants with birth weight less than 1 500 g / 中国新生儿科杂志

Objective:To study the risk factors of extrauterine growth retardation (EUGR) during hospitalization in very preterm infants (VPIs) with birth weight (BW) <1 500 g.Methods:From Jan 2015 to Dec 2020, clinical data of VPIs admitted to neonatal department our hospital were retrospectively studied. The infants were assigned into EUGR group and non-EUGR group according to their weight at discharge. Multivariate logistic regression analysis was used to analyze the risk factors of EUGR in VPIs.Results:A total of 969 VPIs were enrolled, including 400 cases of EUGR (41.3%). Multivariate logistic regression analysis showed that Z-score of BW ( OR=0.057, 95% CI 0.037-0.088, P<0.001) was closely correlated with the occurrence of EUGR and growth velocity (GV) after regain BW ( OR=0.537, 95% CI 0.479-0.602, P<0.001) was a protective factor for EUGR. Maternal hypertension during pregnancy ( OR=1.895, 95% CI 1.059-3.394, P=0.031), asphyxia at birth ( OR=2.508, 95% CI 1.265-3.347, P=0.004) and moderate to severe bronchopulmonary dysplasia (BPD) ( OR=2.660, 95% CI 1.503-4.708, P=0.001) were risk factors for EUGR at discharge. Conclusions:EUGR is still common in VPIs. Increased GV after regain BW, prevention and treatment of moderate to severe BPD may reduce the incidence of EUGR at discharge in VPIs.

Deubiquitination complex platform: A plausible mechanism for regulating the substrate specificity of deubiquitinating enzymes

Deubiquitinating enzymes (DUBs) or deubiquitinases facilitate the escape of multiple proteins from ubiquitin‒proteasome degradation and are critical for regulating protein expression levels in vivo. Therefore, dissecting the underlying mechanism of DUB recognition is needed to advance the development of drugs related to DUB signaling pathways. To data, extensive studies on the ubiquitin chain specificity of DUBs have been reported, but substrate protein recognition is still not clearly understood. As a breakthrough, the scaffolding role may be significant to substrate protein selectivity. From this perspective, we systematically characterized the scaffolding proteins and complexes contributing to DUB substrate selectivity. Furthermore, we proposed a deubiquitination complex platform (DCP) as a potentially generic mechanism for DUB substrate recognition based on known examples, which might fill the gaps in the understanding of DUB substrate specificity.

Effect of superfine powder and aqueous extract of Polygonati Rhizoma on rats with natural perimenopausal syndrome / 中国中药杂志

This study aims to examine the effect of superfine powder and aqueous extract of Polygonati Rhizomaon on natural perimenopausal syndrome in rats and explore the underlying mechanism. To be specific, a total of 60 female SD rats(14-15 months old) with estrous cycle disorder were screened by the vaginal smear and randomized into model control group, β-estradiol 3-benzoate group(0.1 mg·kg~(-1)), superfine powder of Polygonati Rhizoma group(0.25, 0.5 g·kg~(-1)) and aqueous extract of Polygonati Rhizoma group(0.25, 0.5 g·kg~(-1)), and another 10 female SD rats(14-15 months old) were selected as the youth control group. The administration lasted 6 weeks. Then the perimenopausal syndrome-related indexes such as body temperature, microcirculatory blood flow of face and ear, vertigo period, salivary secretion, grip force, and bone strength were determined and open field test was conducted. The immune system-related indexes such as the wet weight and index of thymus and spleen, percentage of T lymphocytes and subgroups in peripheral blood, and hematological indexes were measured. In addition, the ovary-related indexes such as estrous cycle, the wet weight and index of uterus and ovary, ovarian tissue morphology, and cell apoptosis were determined. Moreover, hypothalamus-pituitary-ovary axis(HPO)-related indexes such as serum sex hormone levels, cytochrome P450 family 11 subfamily A member 1(CYP11A1), cytochrome P450 family 19 subfamily A member 1(CYP19A1), and cytochrome P450 family 17 subfamily A member 1(P450 17A1) in ovarian tissue were measured. The results showed that the superfine powder and aqueous extract of Polygonati Rhizoma significantly decreased body temperature(anal, facial and dorsal temperature), microcirculatory blood flow in the ear, and vertigo period, increased salivary secretion, grip force, bone strength, total distance and total speed in the open field test, wet weight and index of thymus and spleen, lymphocyte ratio, CD3~+ level, and CD4~+/CD8~+ ratio, reduced neutrophil number and ratio, estrous cycle disorder ratio, and number of ovarian apoptotic cells, raised wet weight and index of uterus, wet weight of ovary, levels of inhibin B(INHB), estradiol(E_2), anti-müllerian hormone(AMH), and ovarian CYP11A1 and CYP19A1, decreased follicle-stimulating hormone(FSH) and luteinizing hormone(LH) content, and improved ovarian tissue morphology. It is suggested that the superfine powder and aqueous extract of Polygonati Rhizoma can improve the symptoms associated with natural perimenopausal syndrome in rats and enhance ovarian function and immune function. The mechanism is that they regulate HPO axis function by increasing estrogen synthesis.

Immune-related Features of Esophageal Squamous Cell Carcinoma：A Multi-omics Perspective / 中山大学学报(医学科学版)

Esophageal squamous cell carcinoma is a common malignancy in the Asia-Pacific region， especially in China， where the morbidity remains high in spite of the improved overall survival due to advances in medical technology. Immunotherapy becomes a hot spot in recent tumor research when it has provided significant survival benefits in patients with advanced malignant tumors， such as lung cancer， breast cancer， colon cancer， etc. In esophageal squamous cell carcinoma， immunotherapy promotes survival benefit as well. However， because of the complex and changeable biological functions and gene expression regulation of malignant tumors， the conclusions based on a single-omics analysis are often incomprehensive. Currently， most of the immune-related studies on esophageal squamous cell carcinoma are still confined to a single-omics study like genomics， with limitations and one-sidedness. Since multi-omics analysis helps us better understand tumors from a wider and deeper perspective， this review explores and summarizes immune-related features of esophageal squamous cell carcinoma from a multi-omics perspective.

Comparison and improvement of palatability for multisourced oral azithromycin suspension / 药学学报

Azithromycin dry suspension is one of the most commonly used drugs in pediatric clinic, but its taste masking has been difficult to achieve. 5 representative products of azithromycin dry suspension were chose to compare their tastes both using electronic tongue and human sensory evaluation methods, and there existed the differences of bitterness, later bitterness, graininess, and adhesion among these products. Raman micro-imaging was used to determine the difference in taste mainly due to different prescription ingredients and manufacturing techniques. Through mixing the dry suspensions with alkaline mixing solvent, the bad taste of each product was masked after evenly dispersing in the solvent, and their tastes were all close to the taste of the solvent. In the future, it is planned to investigate the stability and bioavailability of the solvent preparations, and then to give the medication suggestion of solvent preparation after ensuring their efficacy.

Virus aerosol transmission, dispersion, and infection probability simulation: A case study in subway carriages / 环境与职业医学

Background Subways are typical congregate settings and may facilitate aerosol transmission of viruses. However, quantified transmission probability estimates are lacking. Purpose To model spread and diffusion of respiratory aerosols in subways by simulation and calculation of infection probabilities. Methods The internal environment of carriages of Shanghai Metro Line 10 was used to establish a study scene. The movement of tiny particles was simulated using the turbulent model. Trend analysis of infection probabilities and viral quantum doses was conducted in a closed subway carriage scene by a quantum emission-infection probability model. Results Under a typical twelve-vent air conditioning configuration, respiratory droplet aerosols within a subway carriage dispersed rapidly throughout various regions due to airflow, with limited short-term diffusion to other carriages. Concurrently, owing to the uncertainty of airflow patterns, the airflow might circulate and converge within carriages, causing delayed outward dispersion or hindered dispersion of droplet aerosols upon entry into these zones. Passengers boarding the carriage could exacerbate the formation of these zones. When the air conditioning system functioned adequately (air exchange rate=23.21 h−1), the probability of a virus carrier transmitting the virus to other passengers within the same carriage via aerosol transmission was approximately 3.8%. However, in the event of air conditioning system failure (air exchange rate=0.5 h−1), this probability escalated dramatically to 30%. Furthermore, a super-spreader (with virus spreading exceeding 90% of the average) elevated the infection probability to 14.9%. Additionally, due to the complexity of turbulence within the carriage, if local diffusion occurred in 1/2 zones of a carriage, the anticipated infection probability would increase to 8.9%, or during the morning or evening rush hours leading to elevated aerosol concentrations, the infection probability would rise to 4.7%. The subway transmission probability for common coronaviruses diminished to as low as 0.9%. Conclusion Combined computational fluid dynamics and infection probability analysis reveals that in the prevalent twelve-vent air conditioning configurations, despite being a major transportation hub with substantial spatial-temporal overlap, the internal space of subway carriages exhibits a certain level of resistance to virus aerosol transmission owing to built-in ventilation capabilities. However, turbulence and passenger positioning may lead to localized hovering of droplet aerosols, thereby increase the risk of virus transmission. Furthermore, super-spreaders, poor operational status of built-in air conditioning system, and high passenger volume at morning or evening peak hours exert profound effects on virus transmission and infection probability.

Prevention and risk factors analysis of lower extremity deep vein thrombosis after high tibial osteotomy / 中华骨科杂志

Objective:To investigate the prevention and risk factors of deep vein thrombosis (DVT) in the lower extremity after medial open wedge high tibial osteotomy (HTO).Methods:A total of 128 patients who underwent medial open wedge HTO in the Third Hospital of Hebei Medical University from January 2020 to October 2022 were retrospectively analyzed, including 45 males and 83 females, aged 59.3±6.8 years (range, 44-87 years). Postoperative anticoagulation with enoxaparin sodium was applied at a randomized dose of 4,000 AXaIU/d or 6,000 AXaIU/d. Gender, age, history of chronic diseases (hypertension, diabetes), smoking history, body mass index, and body fat percentage were collected. On admission, the risk of DVT was assessed using the Caprini scale and calf circumference was measured. Hemoglobin, D-dimer, antithrombin III, activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (FIB), fibrinogen degradation products (FDP), glutathione, glutathione, urea, creatinine, uric acid were recorded. Patients were divided into DVT group and non-DVT group according to whether DVT occurred after operation. Binary logistic regression was used to analyze the independent risk factors of DVT after HTO. The receiver operating characteristic (ROC) curve was plotted, and the area under curve (AUC) was calculated to analyze the predictive value of the postoperative Caprini scale in the occurrence of DVT after HTO.Results:A total of 128 patients were enrolled, 83 patients were treated with enoxaparin sodium 4 000 AXaIU/d and 45 patients were treated with enoxaparin sodium 6 000 AXaIU/d. According to the results of color Doppler examination of bilateral lower extremity veins on the third day after operation, DVT occurred in 39% (50/128) of patients, including 39 cases of calf intermuscular thrombosis, 6 cases of peroneal vein thrombosis, 4 cases of posterior tibial vein thrombosis, and 1 case of popliteal vein thrombosis. DVT occurred in 36% (30/83) of patients receiving 4 000 AXaIU/d enoxaparin sodium and 44% (20/45) of patients receiving 6 000 AXaIU/d enoxaparin sodium, with no statistically significant difference (χ 2=0.84, P=0.358). Univariate analysis showed that smoking history, postoperative Caprini scale≥8, and female may be associated with the development of DVT after HTO ( P<0.05). They were included in the binary logistic regression, and the results showed that postoperative Caprini scale≥8 was an independent risk factor for DVT after HTO. The ROC curve of postoperative Caprini scale for predicting DVT after HTO was drawn, and the AUC was 0.847 (95% CI: 0.73, 0.96), the optimal cut-off value was 8, and the sensitivity and specificity were 84.2% and 77.6%, respectively. Conclusion:Caprini scale≥8 is an independent risk factor for DVT after medial open wedge HTO. Caprini scale has a good value in predicting the occurrence of DVT after HTO. The recommended dose of enoxaparin sodium is 4 000 AXaIU/d for the prevention of postoperative DVT, and increasing the dose is not associated with a decreased risk of DVT.
