Objective:To investigate the current status of maternal body image during pregnancy, mother-infant attachment and postpartum depression and explore the mediating effect of mother-infant attachment on maternal body image during pregnancy and postpartum depression, in order to effectively reduce the incidence of postpartum depression and provide reference and guidance for alleviating depressive symptoms.Methods:A total of 362 pregnant women admitted to obstetric wards in Women′s Hospital of Nanjing Medical University were selected for a cross-sectional investigation by applying the Edinburgh Postnatal Depression Scale, the Body Image in Pregnancy Scale and the Maternal Postnatal Attachment Scale by convenient sampling from July to September 2022. Model 4 in the SPSS macro program PROCESS was used to test the mediating effect of maternal infant attachment between body image and postpartum depression.Results:Totally 362 valid questionnaires were retrieved including 194 individuals aged ≤30 years old and 168 individuals aged >30 years old. The scores of maternal body image during pregnancy, mother-infant attachment and postpartum depression were (89.24 ± 15.56), (71.40 ± 8.05), 7.50 (4.00, 11.00) points.Conclusions:Body image during pregnancy can not only directly predict postpartum depression, but also indirectly predict postpartum depression through the mediating effect of mother-infant attachment. In order to prevent or reduce the occurrence of postpartum depression, nursing staff should carry out intervention research based on influencing the path of postpartum depression from the perspective of positive psychology.

Objective:To explore the anti-inflammatory effect and safety of two non-steroidal anti-inflammatory drugs in the phacoemulsification combined with intraocular lens (IOL) implantation.Methods:A randomized, double-blind, clinical trial was conducted.A total of 90 age-related cataract patients (90 eyes) who were diagnosed in Qingdao Eye Hospital Affiliated to Shandong First Medical University were enrolled from October 2020 to February 2021.The patients were randomized to diclofenac sodium group and bromofenac sodium group by random number table method, with 45 cases (45 eyes) in each group.All patients underwent phacoemulsification combined with IOL implantation, and 0.1% diclofenac sodium eye drops (preservative-free), 4 times a day, and 0.1% pramiphene eye drops, 2 times a day were applied in the perioperative period.The duration of continuous medication treatment and follow-up time were 6 weeks.The subjective symptoms of the patients were scored before and after surgery.The amount of tear fluid secretion was detected by Schirmer I test, and the tear film breakup time was recorded with the Oculus dry eye analyzer.Corneal fluorescein staining was observed under a slit lamp microscope with cobalt blue light.Anterior chamber flash was measured by slit-lamp biomicroscopy.The thickness of central macular area and the presence of macular cystoid edema was measured by optical coherence tomography.Visual acuity, noncontact intraocular pressure (IOP) and the drug safety were examined and evaluated.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Qingdao Eye Hospital (No.[2020]60).All patients were informed about the surgery and postoperative medication and signed the informed consent form.Results:All subjects had no intraoperative complications, and completed treatment and follow-up as required.The preoperative, 1-day postoperative, 1-week postoperative, 6-week postoperative subjective symptom scores were (0.47±0.73), (0.56±0.62), (0.33±0.48), and (0.51±0.66) points in the diclofenac group, and (0.47±0.51), (0.75±0.61), (0.64±0.65), and (0.78±0.77) points in the bromfenac group.There were statistically significant differences in the subjective symptom scores at different time points between the two groups ( Fgroup=5.001, P=0.028; Ftime=2.920, P=0.035), and the subjective symptom scores of diclofenac sodium group were significantly lower than those of bromofenac sodium group (all at P<0.05).The preoperative, 1-week postoperative, 6-week postoperative tear secretion volume were (5.87±2.37), (6.07±2.53), and (6.29±0.25) mm in diclofenac sodium group, and (7.36±2.74), (6.29±3.46), and (5.80±2.76) mm in bromofenac sodium group.There was statistically significant difference in the tear secretion volume between the two groups before surgery ( F=6.910, P=0.012), but there was no significant difference on postoperative weeks 1 and 6 ( F=1.121, 0.772; P=0.729, 0.384).The preoperative, 1-week postoperative, 6-week postoperative non-invasive tear break-up time (NIBUT) were (8.00±6.28), (6.68±5.24), and (6.17±5.00) seconds in diclofenac sodium group, and (6.40±5.28), (4.50±2.46), and (5.39±5.39) seconds in bromofenac sodium group.There was no significant difference in NIBUT between the two groups ( Fgroup=3.415, P=0.068).There was significant difference in NIBUT within groups among different time points ( Ftime=4.358, P=0.020).The 1-day postoperative, 1-week postoperative, 6-week postoperative corneal epithelial staining score were (1.40±0.81), (0.13±0.34), (0.00±0.00) points in diclofenac sodium group, and (1.38±0.89), (0.22±0.47), and (0.00±0.00) points in bromofenac sodium group.There was no statistically significant difference in the corneal epithelial staining score between the two groups after surgery ( Fgroup=0.110, P=0.741).There were statistically significant differences in corneal epithelial staining scores within groups among different time points ( Ftime=175.054, P<0.01).The 1-day postoperative, 1-week postoperative, 6-week postoperative anterior chamber flare classification were 1.13±0.51, 0.13±0.34, and 0.00±0.00 in diclofenac sodium group, and 1.02±0.34, 0.16±0.37, and 0.00±0.00 in bromofenac sodium group.There was no significant difference in the overall anterior chamber flash between the two groups ( Fgroup=0.045, P=0.507).There were statistically significant differences in anterior chamber flash within groups among different time points ( Ftime=322.331, P<0.001).There was no significant difference in the preoperative and 6-week postoperative macular fovea thickness between both groups ( t=-0.221, -0.374; both at P>0.05).The incidence of macular cystoid edema 6 weeks after operation was 0% in both groups.Subjects tolerated the two tested drugs well.Eight adverse events occurred in this study, all of which were mild postoperative IOP elevation, including 3 in diclofenac sodium group with an incidence of 6.67% and 5 in bromofenac group with an incidence of 11.1%.IOP returned to normal in all the patients 1 week after stopping the use of drug. Conclusions:Two nonsteroidal anti-inflammatory drugs are safe and effective for anti-inflammatory treatment after cataract phacoemulsification combined with IOL implantation.The new diclofenac sodium eye drops are more comfortable than bromfenac sodium eye drops.

Objective To observe changes of CT quantitative indexes in patients with untreated chronic obstructive pulmonary disease(COPD)and relationships with pulmonary function indicators.Methods Totally 99 patients with untreated COPD were retrospectively enrolled.According to the degrees of airflow obstruction,the patients were divided into group A(GOLD grade 1 with mild obstruction,n=36),group B(GOLD 2 with moderate obstruction,n=37)and group C(GOLD 3 or 4 with obvious obstruction,n=26).The results of chest CT and pulmonary function tests conducted at the first diagnosis and the follow-up,as well as their correlations were analyzed.CT quantitative indicators included the whole lung volume,low-attenuation areas less than-950 percentage(LAA％),total number of vessels per 1 cm2 of lung surface area(Ntotal/LSA),total number of vessels with area less than 5 mm2 per 1 cm2 of lung surface area(N＜5mm2/LSA),the square root of the wall area of a hypothetical airway with a 10 mm internal perimeter(Pi10),the entire volume,wall thickness and wall area percentage(WA％)of airway wall,etc.,while results of pulmonary function tests included the forced expiratory volume in one second(FEV1)after administration of a bronchodilator,forced vital capacity(FVC),the ratio FEV1/FVC and FEV1 expressed as percent predicted(FEV1％).Results Compared with those at the first diagnosis,the follow-up results of FVC,FEV1,FEV1/FVC,Ntotal/LSA and N＜5mm2/LSA were lower,whereas LAA％,Pi10 and entire volume of airway were all higher in each group(all P＜0.05).Compared with those in group A,group B and C had decreased LAA％and increased Pi10,and the magnitude increased with the severity of airflow obstruction(all P＜0.05).LAA％,Pi1o and entire volume of airway wall were negatively correlated with pulmonary function indicators(all P＜0.05),while Ntotal/LSA and N＜5 mm2/LSA were positively correlated with pulmonary function indicators(all P＜0.05).Conclusion CT quantitative parameters,including LAA％,Ntotal/LSA,N＜5mm2/LSA,Pi10 and entire volume of airway wall were related to pulmonary function,which might reflect the longitudinal changes of airways and blood vessels in COPD patients.

To summarize the experience of Professor WANG Qingguo in diagnosing and treating wind-cold-dampness arthralgia based on the principle that "the nutrient-defense qi does not merge with wind-cold-dampness qi， so it did not result to arthralgia". By analyzing the relationship between nutrient-defense qi and wind-cold-dampness arthralgia， it is believed that the occurrence of wind-cold-dampness arthralgia is closely related to the movement of nutrient qi and defense qi， and the key to the treatment of this disease is to regulate nutrient qi and defense qi and remove the combination of nutrient-defense qi and wind-cold-dampness qi. The core pathogenesis of wind-cold-dampness arthralgia in the early stage is the initial combination of nutrient-defense qi and wind-cold-dampness qi， and the treatment should harmonize nutrient-defense qi and eliminate the pathogen and release pathogenesis， with Chaihu Guizhi Decoction （柴胡桂枝汤） as the main prescription； the core pathogenesis of the middle stage is nutrient-defense qi and wind-cold-dampness qi cemented together， and the treatment should harmonize and tonify nutrient qi and defense qi and separate the pathogen to alleviate disease， with self-prescribed Chuanteng Tongbi Decoction （穿藤通痹汤） as the main prescription； the core pathogenesis of the late stage is deficiency and stagnation of nutrient-defense qi， wind-cold-dampness qi still exist， and the treatment should tonify and free nutrient qi and defense qi to eliminate pathogen and arthralgia， with self-prescribed Chuanqing Haijia Decoction （穿青海甲汤） plus Duhuo Jisheng Decoction （独活寄生汤） as the main prescription.

Objective:To investigate the clinical, cytomorphology, immunocytochemical and molecular features of metastatic melanoma in serosal cavity effusion.Methods:Cytological specimens of 14 patients with melanoma in the chest and abdomen were collected from 2017 to 2023, at the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China. SOX10, S-100 protein, PRAME, BRAF V600E, HMB45, and Melan A were detected by immunocytochemical methods. Fourteen cases were tested for routine antibody combinations, including Claudin4, HEG1, Calretinin, CD68, etc. Four of the patients had biopsy or surgical samples of metastatic solid lesions of primary sites, and further next-generation sequencing (NGS) or amplification refractory mutation system (ARMS)-PCR molecular test was performed. In addition, 30 cases of serosal effusion samples were collected as control groups (10 cases of benign mesothelial cell reactive hyperplasia, 10 cases of mesothelioma, and 10 cases of metastatic lung adenocarcinoma).Results:Among the 14 cases of melanoma, there were 7 males and 7 females, with ages ranging from 35 to 86 years, and an average age of 57 years, there 10 cases aged ≥50 years. The tumor cells in the serosal effusion varied in morphology and degree of atypia. SOX10 was positive in all 14 cases (14/14), S-100 protein was positive in 10 cases (10/14), PRAME was positive in 12 cases (12/14), BRAF V600E was positive in 10 cases (10/14), HMB45 was positive in 12 cases (12/14), and Melan A was positive in 13 cases (13/14). In 4 patients with histological correlation, the cytological and histological expression of SOX10, BRAF V600E, and PRAME was positive in all 4 cases (4/4); S-100 protein was positive in 2 cases (2/4); and HMB45 and Melan A were positive in 3 cases (3/4). Using NGS or ARMS-PCR, missense mutations of BRAF V600E were detected in all 4 patients; TERT promoter mutations was detected in 1 case; and CDKN2A terminating mutations and MSI1 deletion mutations were detected in the other case. SOX10, S-100, HMB45, Melan A, PRAME and BRAF V600E were all negative in 30 control samples of serosal cavity effusion.Conclusion:By observing the morphology of tumor cells, immunocytochemical test of several combination markers, especially the expression of SOX10, BRAF V600E and PRAME, can help to improve the positive diagnosis rate of melanoma in serous cavity effusion.

Objective To analyze the relationship between the fat content of supraspinatus muscle measured by spectral CT fat-muscle material decomposition technology and the tendon tear severity(TTS)of supraspinatus,as well as shoulder joint function.Methods A total of 108 patients were prospectively selected to undergo routine MRI and spectral CT imaging of the shoulder joints.The patients were divided into normal,degenerative,partial tear,and full-thickness tear groups based on MRI findings.A fat-muscle material decomposition image was generated through spectral analysis to measure the fat content of supraspinatus muscle.The differences in fat content of supraspinatus muscle between the groups were compared,and correlation analyses were performed between the fat content of supraspinatus muscle and the clinical baseline characteristics,symptom duration,and Constant-Murley scores in patients with supraspinatus tendon tears.Results Comparison of supraspinatus muscle fat content among the four groups:the full-thickness tear group＞the partial tear group＞the degenerative group＞the normal group(P＜0.05).There was a strong positive cor-relation between the supraspinatus muscle fat content and the supraspinatus TTS(r=0.654,P＜0.05).Among patients with partial and full-thickness tears of the supraspinatus tendon,there was a moderate positive correlation between supraspinatus muscle fat content and patient age(r=0.393,P＜0.05),a weak positive correlation with gender(r=0.199,P＜0.05),with higher fat content observed in females compared to males,no significant correlation with symptom duration(r=0.037,P＞0.05),a moderate positive correla-tion with body mass index(BMI)(r=0.463,P＜0.05),and a moderate negative correlation with Constant-Murley score(r=-0.316,P＜0.05).Conclusion In patients with rotator cuff tears,the quantitative fat content of supraspinatus muscle based on spectral CT fat-muscle material decomposition technology is strongly positively correlated with rotator cuff injury degree,and is also correlated with patient age,gender,BMI,and the strength of the shoulder joint muscles and range of the motion.

Silicosis is a leading cause of occupational disease-related morbidity and mortality worldwide, but the molecular basis underlying its development remains unclear. An accumulating body of evidence supports gasdermin D (GSDMD)-mediated pyroptosis as a key component in the development of various pulmonary diseases. However, there is little experimental evidence connecting silicosis and GSDMD-driven pyroptosis. In this work, we investigated the role of GSDMD-mediated pyroptosis in silicosis. Single-cell RNA sequencing of healthy and silicosis human and murine lung tissues indicated that GSDMD-induced pyroptosis in macrophages was relevant to silicosis progression. Through microscopy we then observed morphological alterations of pyroptosis in macrophages treated with silica. Measurement of interleukin-1β release, lactic dehydrogenase activity, and real-time propidium iodide staining further revealed that silica induced pyroptosis of macrophages. Additionally, we verified that both canonical (caspase-1-mediated) and non-canonical (caspase-4/5/11-mediated) signaling pathways mediated silica-induced pyroptosis activation, in vivo and in vitro. Notably, Gsdmd knockout mice exhibited dramatically alleviated silicosis phenotypes, which highlighted the pivotal role of pyroptosis in this disease. Taken together, our results demonstrated that macrophages underwent GSDMD-dependent pyroptosis in silicosis and inhibition of this process could serve as a viable clinical strategy for mitigating silicosis.

This article aims to comprehensively review the concept, etiology, classification, classical cortical mapping, assessment, a proposed flowchart for the diagnosis and differential diagnosis, treatment, rehabilitation, mechanisms of development and recovery, prognosis, and influencing factors for post-stroke aphasia(PSA)types in the Chinese language.We emphasize the necessity and significance of neuroimaging assessment of the brain and blood vessels and neuropsychological assessment in the diagnosis and differential diagnosis of PSA in Chinese.We also recommend and encourage the use of the dichotomies of internal vs.external and anterior vs.posterior as a starting point, based on the association of anatomical locations of the brain and blood vessels with brain language areas and language disorders.A classification system of PSA in Chinese developed from this approach in the form of a flowchart is well-suited for guiding the clinical treatment of cerebral stroke.Incorporating the "four elements" , the flowchart enables convenient diagnosis, classification and differential diagnosis of PSA in Chinese and facilitates targeted and personalized rehabilitation planning to benefit the patient.This article introduces the use of memantine, piracetam, donepezil and other drugs for PSA treatment, evaluates clinical trials on memantine conducted in China and abroad and its mechanisms of action for the treatment of PSA, and discusses how rehabilitation therapy achieves therapeutic effects.For the treatment of PSA, clinical research and practice using drugs such as memantine, piracetam and donepezil in combination with non-pharmacotherapy and rehabilitation training should be promoted.
