ABSTRACT

Objective To compare the application effects of simple artery ligation and modified inflation-deflation method in determining the lung intersegment plane during thoracoscopic precision segmentectomy.Methods A total of 80 patients who underwent thoracoscopic precision segmentectomy in our hospital from August 2021 to February 2023 were prospectively included and divided into the observation group and the control group by random number table method,with 40 cases in each group.Patients in the observation group were determined the lung intersegment plane by simple artery ligation,while patients in the control group were determined the lung intersegment plane by modified inflation-deflation method.The perioperative related indexes,lung function indexes,postoperative complications and follow-up of patients between the two groups were compared.Results The operative time and blood loss of patients in the observation group were significantly shorter/lower than those in the control group(P<0.05).There was no significant difference in the time to reveal the interseg-mental planes, total drainage volume after operation, indwelling time of drainage tube, postoperative hospital stay or lung segmentectomy distribution of patients between the two groups (P>0. 05). The percentage of forced vital capacity to the predicted values (FVC%pred) and percentage of forced expiratory volume in 1 second to the predicted values (FEV1%pred) after operation of patients in the two groups were significantly decreased compared with those before operation (P<0. 05), and FVC%pred and FEV1%pred after operation of patients in the observation group were significantly higher than those in the control group (P<0. 05). There was no statistically significant difference in the occurrence of postoperative complications of patients between the two groups (P>0. 05). There was no death, local recurrence or distant metastasis occurred in all patients during follow-up. Conclusion Compared with the modified inflation-deflation method, the application of simple artery ligation to determine the intersegment plane during thoracoscopic precision segmentectomy has significant advantages such as simple operation, less injury, and less impact on the lung function of patients, which is a feasible and effective technique, with high safety.

ABSTRACT

To investigate the protective effect and the potential mechanism of leonurine(Leo) against erastin-induced ferroptosis in human renal tubular epithelial cells(HK-2 cells), an in vitro erastin-induced ferroptosis model was constructed to detect the cell viability as well as the expressions of ferroptosis-related indexes and signaling pathway-related proteins. HK-2 cells were cultured in vitro, and the effects of Leo on the viability of HK-2 cells at 10, 20, 40, 60, 80 and 100 μmol·L~(-1) were examined by CCK-8 assay to determine the safe dose range of Leo administration. A ferroptosis cell model was induced by erastin, a common ferroptosis inducer, and the appropriate concentrations were screened. CCK-8 assay was used to detect the effects of Leo(20, 40, 80 μmol·L~(-1)) and positive drug ferrostatin-1(Fer-1, 1, 2 μmol·L~(-1)) on the viability of ferroptosis model cells, and the changes of cell morphology were observed by phase contrast microscopy. Then, the optimal concentration of Leo was obtained by Western blot for nuclear factor erythroid 2-related factor 2(Nrf2) activation, and transmission electron microscope was further used to detect the characteristic microscopic morphological changes during ferroptosis. Flow cytometry was performed to detect reactive oxygen species(ROS), and the level of glutathione(GSH) was measured using a GSH assay kit. The expressions of glutathione peroxidase 4(GPX4), p62, and heme oxygenase 1(HO-1) in each group were quantified by Western blot. RESULTS:: showed that Leo had no side effects on the viability of normal HK-2 cells in the concentration range of 10-100 μmol·L~(-1). The viability of HK-2 cells decreased as the concentration of erastin increased, and 5 μmol·L~(-1) erastin significantly induced ferroptosis in the cells. Compared with the model group, Leo dose-dependently increased cell via-bility and improved cell morphology, and 80 μmol·L~(-1) Leo promoted the translocation of Nrf2 from the cytoplasm to the nucleus. Further studies revealed that Leo remarkably alleviated the characteristic microstructural damage of ferroptosis cells caused by erastin, inhibited the release of intracellular ROS, elevated GSH and GPX4, promoted the nuclear translocation of Nrf2, and significantly upregulated the expression of p62 and HO-1 proteins. In conclusion, Leo exerted a protective effect on erastin-induced ferroptosis in HK-2 cells, which might be associated with its anti-oxidative stress by activating p62/Nrf2/HO-1 signaling pathway.

ABSTRACT

OBJECTIVES@#To study the clinical features of children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infection.@*METHODS@#A retrospective analysis was performed on the medical data of 201 children with coronavirus disease 2019 (COVID-19) who were hospitalized and diagnosed with SARS-CoV-2 Omicron variant infection in Quanzhou First Hospital from March 14 to April 7, 2022. Among the 201 children, there were 34 children with asymptomatic infection and 167 with symptomatic infection. The two groups were compared in terms of clinical features, results of experimental examinations, and outcome.@*RESULTS@#Of all the 201 children, 161 (80.1%) had a history of exposure to COVID-19 patients and 132 (65.7%) had a history of COVID-19 vaccination. Among the 167 children with symptomatic infections, 151 had mild COVID-19 and 16 had common COVID-19, with no severe infection or death. Among the 101 children who underwent chest CT examination, 16 had ground glass changes and 20 had nodular or linear opacities. The mean time to nucleic acid clearance was (14±4) days for the 201 children with Omicron variant infection, and the symptomatic infection group had a significantly longer time than the asymptomatic infection group [(15±4) days vs (11±4) days, P<0.05]. The group vaccinated with one or two doses of COVID-19 vaccine had a significantly higher positive rate of IgG than the group without vaccination (P<0.05). The proportions of children with increased blood lymphocyte count in the symptomatic infection group was significantly lower than that in the asymptomatic infection group (P<0.05). Compared with the asymptomatic infection group, the symptomatic infection group had significantly higher proportions of children with increased interleukin-6, increased fibrinogen, and increased D-dimer (P<0.05).@*CONCLUSIONS@#Most of the children with Omicron variant infection have clinical symptoms, which are generally mild. The children with symptomatic infection are often accompanied by decreased or normal blood lymphocyte count and increased levels of interleukin-6, fibrinogen, and D-dimer, with a relatively long time to nucleic acid clearance. Some of them had ground glass changes on chest CT.

ABSTRACT

OBJECTIVES@#To study the effect of early use of sodium valproate on neuroinflammation after traumatic brain injury (TBI).@*METHODS@#A total of 45 children who visited in Xuzhou Children's Hospital Affiliated to Xuzhou Medical University from August 2021 to August 2022 were enrolled in this prospective study, among whom 15 healthy children served as the healthy control group, and 30 children with TBI were divided into a sodium valproate treatment group and a conventional treatment group using a random number table (n=15 each). The children in the sodium valproate treatment group were given sodium valproate in addition to conventional treatment, and those in the conventional group were given an equal volume of 5% glucose solution in addition to conventional treatment. The serum concentrations of nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3), high-mobility group box 1 (HMGB1), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) were measured in the healthy control group on the day of physical examination and in the children with TBI on days 1, 3, and 5 after admission. Glasgow Outcome Scale-Extended (GOS-E) score was evaluated for the children with TBI 2 months after discharge.@*RESULTS@#Compared with the healthy control group, the children with TBI had significantly higher serum concentrations of NLRP3, HMGB1, TNF-α, and IL-1β on day 1 after admission (P<0.017). The concentration of NLRP3 on day 5 after admission was significantly higher than that on days 1 and 3 after admission in the children with TBI (P<0.017). On days 3 and 5 after admission, the sodium valproate treatment group had a significantly lower concentration of NLRP3 than the conventional treatment group (P<0.05). For the conventional treatment group, there was no significant difference in the concentration of HMGB1 on days 1, 3, and 5 after admission (P>0.017), while for the sodium valproate treatment group, the concentration of HMGB1 on day 5 after admission was significantly lower than that on days 1 and 3 after admission (P<0.017). On day 5 after admission, the sodium valproate treatment group had a significantly lower concentration of HMGB1 than the conventional treatment group (P<0.05). For the children with TBI, the concentration of TNF-α on day 1 after admission was significantly lower than that on days 3 and 5 after admission (P<0.017). On days 3 and 5 after admission, the sodium valproate treatment group had a significantly lower concentration of TNF-α than the conventional treatment group (P<0.05). The concentration of IL-1β on day 3 after admission was significantly lower than that on days 1 and 5 after admission (P<0.017) in the children with TBI. On days 3 and 5 after admission, the sodium valproate treatment group had a significantly lower concentration of IL-1β than the conventional treatment group (P<0.05). The GOS-E score was significantly higher in the sodium valproate treatment group than that in the conventional treatment group 2 months after discharge (P<0.05).@*CONCLUSIONS@#Early use of sodium valproate can reduce the release of neuroinflammatory factors and improve the prognosis of children with TBI.

ABSTRACT

OBJECTIVE@#To investigate the enhancement of macrophage chemotaxis in patients with knee osteoarthritis (KOA) and its correlation with the disease severity.@*METHODS@#Eighty patients with KOA admitted from July 2019 to June 2022 were enrolled as the observation group and divided into 29 cases of moderate group, 30 cases of severe group and 21 cases of extremely severe group. At the same time, 30 healthy subjects were included as the control group. The gene expressions of NF-κB, CXC chemokine receptor 7 (CXCR7) and CXC chemokine ligand 12 (CXCL12) in macrophages of each group were analyzed. Visual analogue scale(VAS) was used to evaluate the degree of joint pain. Joint function was evaluated by knee Joint Society Scoring system(KSS). Finally, data analysis was carried out.@*RESULTS@#The expression levels of NF-κB, CXCR7 and CXCL12 in moderate group, severe group and extreme recombination group were higher than those in control group. The VAS, the expression of NF-κB, CXCR7 and CXCL12 in the severe group and the extreme recombination group were higher than those in the moderate group, whereas KSS was lower than that in the moderate group. The VAS, expression levels of NF-κB, CXCR7 and CXCL12 in the extremely severe group were higher than those in the severe group, and KSS was lower than that in the severe group (all P<0.01). The expression levels of NF-κB, CXCR7 and CXCL12 in macrophages were positively correlated with VAS score, but negatively correlated with KSS(all P<0.01). The expression levels of NF-κB, CXCR7 and CXCL12 in macrophages were positively correlated with the severity of disease. After excluding the influence of traditional factors (gender, age and disease duration), multiple linear regression analysis further showed that the expression levels of NF-κB, CXCR7 and CXCL12 were still positively correlated with the severity of disease(all P<0.01).@*CONCLUSION@#The chemotaxis of macrophages in patients with KOA increased with the aggravation of the disease, and was related to the degree of pain and function impairment.

ABSTRACT

Objective To investigate the effect of rehabilitation training combined with acupuncture ( RTA) on upper limb function of stroke patients by Kinect. Methods Stroke patients with upper limb dysfunction werrandomly divided into control group (rehabilitation training) and treatment group ( RTA), with 15 cases in each group. The modified Barthel Index ( MBI), Fugl Meyer assessment ( FMA), and Wolf motor function test (WMFT) were compared between two groups before and after treatment. The changes in motor time ( MT), motor unit number (MUN), index of curvature (IC), elbow flexion angle (EFA), shoulder flexion angle (SFA),and shoulder adduction angle ( SAA) during three actions, namely, placing forearm on the table, extending elbow and drinking water, were evaluated by Kinect and then compared between two groups before and after treatment. Results After 6 weeks of intervention, the scores of MBI, FMA, WMFT and elbow extension in treatment group were higher than those in control group (P<0. 05). The scores of MBI, FMA, WMFT and three actions after treatment were higher than those before treatment (P<0. 05). For three actions, the improvement of MT, MUN, IC, EFA, SFA, and SAA in treatment group were better than those in control group ( P< 0. 05). Compared with pre-treatment, for the action of forearm placement on the table and elbow extension, both treatment group and control group showed an increase in EFA (P<0. 05), and a decrease in MT, MUN, IC, SFA and SA (P<0. 05). For the action of drinking water, both treatment group and control group showed an increase in EFA and SAA (P< 0. 05), and a decrease in MT, MUN, IC and SAA ( P< 0. 05). Conclusions RTA can improve the upper limb function of stroke patients. Kinect can accurately reflect the changes in upper limb function of stroke patients, and it is suitable for clinical work.

ABSTRACT

The pregnancy rate of young breast cancer patients is far lower than that of the general population, which is possibly related to many factors such as patients' concern about tumor recurrence, ovarian dysfunction caused by chemotherapy, long endocrine treatment cycle, lack of professional multidisciplinary cooperation team and so on. At present, there is limited data on fertility preservation before tumor treatment and successful pregnancy and delivery after treatment for young breast cancer patients. In order to successfully carry out the fertility preservation of young female breast cancer patients, strengthen their physical and mental health, promote the return of social roles and improve the health level of their offsprings, this article reviews the factors affecting fertility, the appropriate population for fertility preservation, and the impact on the prognosis of breast cancer, as well as the timing and methods of fertility preservation and recovery opportunities in young women with breast cancer.

ABSTRACT

Objective:To investigate the current status of women′s level of birth experience and lactation initiation time and explore the effect of level of birth experience on lactation initiation time.Methods:This was a cross-sectional study. A convenience sampling method was used to select 622 maternal cases attending the Affiliated Hospital of Jining Medical College from November, 2020 to January, 2021, and the distribution of their labor experience level and lactation initiation time was investigated by questionnaire and follow-up assessment.Results:There were 622 women with transvaginal deliveries who had lactation initiation times of more than 72 h in 241 cases (38.75%). The scores for each dimension of the Childbirth Experience Questionnaire (CEQ) were (49.63 ± 8.58)points, and the scores for each dimension of CEQ were perceived safety, professional support, involvement and self-efficacy in descending order. The results of the correlation analysis showed that there was a negative correlation between the scores on each dimension of CEQ and the total score and lactation initiation time ( r values were -0.436 to -0.146, all P<0.01). Stratified regression analysis showed that after controlling for age, number of births, gestational weeks of labour, illness during pregnancy and labour analgesia as the underlying variables affecting lactation initiation time, the scores for self-efficacy, involvement, perceived safety and professional support in the CEQ all affected lactation initiation time after delivery ( t values were -6.76 to -2.02, all P<0.05). Conclusions:The birth experience and lactation of women who deliver via vaginal birth need to be taken into account. The more negative the birth experience, the longer the lactation initiation time. The women′s involvement in the birth process, their own competence, perceived safety and level of professional support are all valid influencing indicators of lactation initiation time.

ABSTRACT

Transposons are the most prevalent elements in human genomes, which plays a vital role in gene expression regulation and evolutionary processes. They also jeopardize genome integrity with the characteristics of jumping and insertions. A delicate balance is maintained between the benefits and deleterious aspects of transposons, mediated by the epigenetic regulatory system. Once the balance is broken, it will give rise to genomic instability, leading to neoplasia. A lot of studies have shown that the transcriptional activation, expression products and methylation of transposons are closely related with urological malignancies, holding tremendous potential as biomarkers for risk and effect prediction, noninvasive diagnosis and targeted therapies of urological malignancies. In this article, the molecular mechanisms of transposons underlying the initiation, promotion and progression of urological malignancies as well as advances in diagnosis and treatment are reviewed.

ABSTRACT

Objective:To investigate the effect of Candida albicans ( C. albicans) on pyroptosis of murine bone marrow-derived macrophages (BMDMs) . Methods:Live-cell imaging was used to observe morphologic changes of in vitro C. albicans-infected BMDMs (multiplicity of infection [MOI] = 50) so as to evaluate whether pyroptosis occurred. Cultured BMDMs were divided into a control group and a C. albicans group, which were treated with phosphate-buffered saline and C. albicans suspensions respectively for 6 hours; then, real-time fluorescence-based quantitative PCR was performed to determine the mRNA expression of NOD-like receptor pyrin domain containing 3 (NLRP3), interleukin (IL) -1β and IL-18, and Western blot analysis to determine the protein expression and cleavage levels of NLRP3, caspase-1 and gasdermin D (GSDMD). BMDMs were cultured with C. albicans suspensions for different durations (0, 10, 15, 20, and 25 hours), and enzyme-linked immunosorbent assay was conducted to detect secretion levels of IL-1β and IL-18. Cultured wild-type BMDMs and GSDMD-knockout BMDMs were treated with C. albicans suspensions for 15 minutes, and then rates of phagocytosis of C. albicans by wild-type BMDMs and GSDMD-knockout BMDMs were estimated by flow cytometry; after 6-hour treatment with C. albicans, flow cytometry and lactate dehydrogenase (LDH) release assay were performed to assess mortality rates of wild-type BMDMs and GSDMD-knockout BMDMs. In addition, some wild-type BMDMs and GSDMD-knockout BMDMs were separately divided into blank control group, control group, maximum enzyme activity-sample control group, IL-1β alone group, C. albicans alone group, and IL-1β + C. albicans group, and cell mortality rates were detected by the LDH release assay after treatment with IL-1β and/or C. albicans. Statistical analysis was carried out by using unpaired t test, Kruskal-Wallis test, analysis of variance, and other statistical methods. Results:After in vitro treatment with C. albicans, swelling and ballooning with large bubbles blowing from the plasma membrane occurred in BMDMs, suggesting the occurrence of cell pyroptosis; compared with the control group, the C. albicans group showed significantly increased mRNA expression levels of NLRP3 and IL-1β after 6-hour treatment with C. albicans ( t = 13.02, 17.51, respectively, P = or < 0.001), but no significant change in the IL-18 mRNA expression level ( P = 0.486), and Western blot analysis showed that C. albicans could increase the expression of NLRP3 inflammasomes, as well as cleaved caspase-1 and GSDMD. After the treatment with C. albicans for different durations (0, 10, 15, 20, and 25 hours), the secretion level of IL-1β by BMDMs gradually increased over time ( H = 12.90, P = 0.012), while the secretion level of IL-18 did not significantly change ( F = 0.48, P = 0.753), and the secretion level of IL-1β was significantly lower in the GSDMD-knockout BMDM group than in the wild-type BMDM group ( F = 24.22, P = 0.008). After 15-minute in vitro treatment with C. albicans, the phagocytosis rate of C. albicans was significantly lower in the GSDMD-knockout BMDM group (50.3% ± 1.10%) than in the wild-type BMDM group (58.53% ± 1.19%, t = 5.09, P = 0.007) ; after 6-hour treatment with C. albicans, the cell mortality rate was significantly higher in the GSDMD-knockout BMDM group than in the wild-type BMDM group (flow cytometry: 38.40% ± 0.50% vs. 34.37% ± 0.52%, t = 4.72, P = 0.009; LDH release assay: 22.52% ± 0.18% vs. 12.48% ± 0.15%, t = 42.36, P < 0.001) ; the cell mortality rates of wild-type BMDMs and GSDMD-knockout BMDMs both significantly decreased in the IL-1β + C. albicans groups compared with the C. albicans groups (both P < 0.001) . Conclusion:Pyroptosis could be induced in murine BMDMs after C. albicans infection, which promotes the release of IL-1β and may reduce the mortality rate of macrophages by improving their immune activity.

ABSTRACT

Objective:To analyze the prevalence of parturiophobia and its association with preferred mode of delivery in pregnant women in Changning District, Shanghai.Methods:A cross- sectional study was conducted among 1 560 pregnant women in the third trimester who had their antenatal examination in Changning Maternity and Infant Health Hospital from September 2020 to March 2021. Fear of childbirth was measured with a validated Chinese version of Wijma Delivery Expectancy/Experience Questionnaire version A (W-DEQ-A). Based on the W-DEQ-A scores, the participants were divided into two groups: non-clinical parturiophobia group [<85 scores, including mild (≤37 scores), moderate (38-65 scores) and severe (66-84 scores) parturiophobia] and clinical parturiophobia group (≥85 scores). Rank-sum test, Chi-square test and t-test were used for univariate analysis. Multivariate binary logistic regression was used to analyze the factors associated with fear of childbirth and its relationship with preferred mode of delivery. Results:The detection rates of mild, moderate, severe and clinical parturiophobia were 18.8% (294/1 560), 44.9% (700/1 560), 31.1% (485/1 560) and 5.2% (81/1 560), respectively. Multivariate binary logistic regression showed that the participants who were supported by relatives and friends to have cesarean section ( OR=3.45, 95% CI: 1.29-9.22) or had antenatal anxiety ( OR=4.73, 95% CI: 2.49-8.97) were more likely to have clinical parturiophobia, while those with planned pregnancy ( OR=0.49, 95% CI: 0.29-0.82), high intensity physical activity ( OR=0.36, 95% CI: 0.18-0.72) or better/well understanding of the delivery process ( OR=0.42, 95% CI: 0.19-0.97) were less likely to develop clinical parturiophobia (all P<0.05). Compared with the non-clinical parturiophobia women, those with clinical parturiophobia were more likely to choose cesarean section ( OR=2.15, 95% CI: 1.22-3.78, P=0.008). Conclusions:The detection rates of severe and clinical parturiophobia are 31.1% and 5.2% in Changning District, Shanghai. The associated factors mainly include the attitudes of relatives and friends towards the mode of delivery, antenatal anxiety, planned pregnancy or not, physical activity level and the understanding of delivery process. Clinical parturiophobia might be an important factor for cesarean section on maternal request.

ABSTRACT

Objective:To analyze the trend, hotspots and frontiers of diabetic retinopathy (DR) therapy by bibliometric method.Methods:Data were taken from the Web of Science website of Science Citation Index. Articles from 2017 to 2021, which were related to the therapy of diabetic retinopathy (DR), were included. The bibliometric analysis softwares, VOSviewer and CiteSpace were used to generate and analyze visual representations of the complex data input, including high-frequency keywords, keywords with the strongest citation bursts and co-occurrence networks of keywords.Results:A total of 3,845 articles were included. The amounts of papers published from 2017 to 2021 is 633, 651, 708, 893, and 960 respectively, increasing over years. Chinese scholars published the most articles, followed by the United States. The number of articles funded by the National Natural Science Foundation of China ranks third. There were 47 high-frequency keywords clustered into DR treatment, pathogenesis of DR, diagnosis of DR, Oxidative stress, diabetic macular edema (DME), type 2 diabetes, optical coherence tomography and deep learning. Those keywords were research hotspots and new keywords were constantly emerging. Among the top 11 burst words, the burst values of "intravitreal bevacizumab", "vascular endothelial growth factor (VEGF)", "choroidal neovascularization", "inhibition", and "receptors" were all over 10. Highly cited references showed a significant clustering tendency, which were treatment of DME, review of DR, clinical research of anti-VEGF drug therapy.Conclusions:The amount of paper related to DR therapy is on the rise; the specific treatment methods for the pathogenesis of DR are constantly research hotspots. In addition, formulating treatment strategies to reduce macular edema and other complications of diabetes, applying optical coherence tomography, deep learning and other technologies to improve the efficiency of DR diagnosis and treatment, improve targeted drug delivery systems, and finding new target points were research frontiers.

ABSTRACT

Cancer is the most important leading cause of death worldwide, with about 10 million deaths caused by cancer in 2020. In situ gel drug delivery systems have attracted much attention in the field of pharmacy and biotechnology due to their good histo-compatibility, excellent injectability, high drug delivery capacity, slow-release drug delivery, and less influence by the in vivo environment. Meanwhile, in situ gel can be combined with chemotherapy, photo-thermal therapy, chemokinetic therapy, immunotherapy and so on to deliver drugs into the tumor site in a less invasive way without surgical operation, forming a semi-solid gel reservoir in the tumor site to realize in situ tumor combined therapy. In this paper, the author summarized the research progress of anti-tumor in situ gel delivery system in the past 10 years, introduced its commonly used polymer materials, classification principles and specific application examples, and finally summarized and discussed the key issues, in order to provide reference for the development of new anti-tumor drug delivery system in the future.
