AIM: To investigate the current status of retinopathy of prematurity(ROP)in premature infants in Xiamen and analyze its influencing factors, aiming to provide a scientific basis for clinical treatment and preventive strategies.METHODS: A retrospective study was conducted on the case data of 363 preterm infants with a gestational age of <32 wk who underwent fundus examination at Xiang'an Hospital of Xiamen University from February 11, 2020 to February 25, 2023. The incidence of ROP was statistically analyzed based on the screening results. All premature infants were divided into ROP group(37 cases, 64 eyes)and non-ROP group(326 cases, 652 eyes). General clinical data and perinatal-related information of the two groups were compared, and multivariate Logistic regression analysis was used to identify factors influencing the occurrence of ROP in premature infants.RESULTS: A total of 363 premature infants were included in this study. The fundus screening results showed that a total of 37 cases(64 eyes)of premature infants were detected with ROP, including 10 cases(10 eyes)monocular and 27 cases(54 eyes)binocular, with an overall incidence of 10.2%(37/363). The severity was determined according to the ROP international classification standard(ROP is divided into 5 stages, with stage I being the least severe and stage V the most severe). Among the 64 eyes, 30 eyes(46.9%)were in stage I, 20 eyes(31.3%)were in stage II, 10 eyes(15.6%)were in stage III, 4 eyes(6.3%)were in stage IV, and there were no cases in stage V. By comparing the clinical data of the two groups, no significant differences were found in gender, mode of delivery, singleton or multiple births, premature rupture of membranes, history of asphyxia, patent ductus arteriosus(PDA), or neonatal respiratory distress syndrome(NRDS)between the two groups(all P>0.05). However, premature infants in the ROP group had significantly younger gestational age and lower birth weight compared to those in the non-ROP group(all P<0.05). Additionally, the ROP group had higher proportions of longer hospital stays, bronchopulmonary dysplasia(BPD), neonatal sepsis, anemia, oxygen therapy for more than 1 wk, oxygen concentration above 40%, and blood transfusion treatment(all P<0.05). Multivariate Logistic regression analysis revealed that combined neonatal sepsis(OR=166.985, 95% CI: 35.239-791.277, P<0.001), anemia(OR=8.111, 95% CI: 2.064-31.871, P=0.003), oxygen use time >1 wk(OR=10.216, 95% CI: 2.543-41.039, P=0.001), oxygen therapy concentration >40%(OR=7.647, 95% CI: 1.913-30.566, P=0.004), and receiving blood transfusion therapy(OR=5.879, 95% CI: 1.412-24.470, P=0.015)were the main risk factors affecting the occurrence of ROP in preterm infants, and the higher birth weight of preterm infants was a protective factor for ROP(OR=0.093, 95% CI: 0.022-0.394, P=0.001).CONCLUSION: The incidence of ROP in premature infants is relatively high, and there are multiple influencing factors. Low birth weight, neonatal sepsis, anemia, oxygen therapy, and blood transfusion treatment are high-risk factors for ROP in premature infants. Clinical attention should be given to such infants, and fundus screening should be conducted in a standardized manner to provide early treatment, thereby further reducing the risk of ROP in premature infants.

Objective:To explore the genetic etiology of fetuses with congenital heart disease (CHD) through whole exome sequencing (WES).Methods:Thirty seven fetuses identified with CHD by prenatal ultrasonography but with negative results by chromosomal microarray analysis (CMA) at Jinhua Maternal and Child Health Care Hospital from January 2020 to June 2022 were selected as the study subjects, for whom WES was carried out.Results:WES and Sanger sequencing had detected 6 pathogenic or likely pathogenic variants, and 6 variants with unknown clinical significance. The variants had involved 15 loci within 11 genes, in addition with one copy number variation.Conclusion:WES can increase the detection rate for genetic abnormalities among fetuses with CHD, which can facilitate the prenatal diagnosis, evaluation of prognosis and genetic counseling for the couples.

Objective To investigate the reversal effect and mechanism of cinobufagin(CBG)on cisplatin resist-ance in human ovarian cancer cells.Methods A2780 cell line and its cisplatin-resistant cell line A2780/DDP are common ovarian cancer cells in clinic,so these two cell lines were selected as the research objects.The cell viabil-ity was detected by cell Counting Kit-8(CCK-8)assay,and the cell proliferation ability was detected by plate clo-ning and 5-ethynyl-2′-deoxyuridine(EdU)assay.Hoechst staining was used to observe cell apoptosis.Cell scratch test and Transwell test were used to evaluate cell migration and invasion ability.Western blot and quantitative reverse transcription PCR(RT-qPCR)were used to detect the protein and mRNA expressions of phosphatidylinosi-tol 3-kinase/protein kinase(PI3K/AKT)signaling pathway and epithelial-mesenchymal transition(EMT).Re-sults Compared with A2780 cells,the drug resistance indexes of A2780/DDP cells were 5.636,5.864,5.695,respectively.After treatment of A2780/DDP cells with CBG(2,4,6 mg/ml),the reversal resistance indexes were 1.617,2.570,3.461,respectively.CBG treatment significantly increased the level of apoptosis and inhibi-ted the proliferation,migration and invasion of the cells in a concentration-dependent manner(P<0.05).Western blot results showed that compared with A2780 cells,the relative ratio of P-PI3K/PI3K and P-AKT/AKT protein levels,as well as the protein expression of N-cadherin,Vimentin,and Snail were higher in the control group(A2780/DDP)cells,while the protein expression of E-cadherin was lower(tP-PI3K/PI3K=8.115,tP-AKT/AKT=17.62,tN-cadherin=6.126,tVimentin=4.001,tSnail=17.333,tE-cadherin=4.620,P<0.01);As the dose of CBG increased,the protein expression levels of P-PI3K,P-AKT,N-cadherin,Vimentin,and Snail in drug-resistant cells de-creased,while the protein expression level of E-cadherin increased(FP-PI3K=268.5,FP-AKT=190.5,FN-cadherin=24.02,FVimentin=57.65,FSnail=87.24,FE-cadherin=135.8,P<0.05).qRT-PCR results showed that with the in-crease of CBG concentration,the mRNA expression levels of PI3K,AKT,N-cadherin,Vimentin and Snail de-creased,while the mRNA expression level of E-cadherin gradually increased(FPI3K=101.1,FAKT=558.3,FN-cadherin=86.97,FVimentin=105.9,FSnail=85.71,FE-cadherin=80.96,P<0.01).Conclusion CBG can reverse cisplatin resistance of ovarian cancer A2780/DDP cell line,and its mechanism may be related to the regulation of PI3K/AKT signaling pathway and inhibition of EMT by CBG.

Objective:To systematically review the medical decision-making for children with autism spectrum disorder (ASD) from the perspective of caregivers.Methods:It was a systematic review. Using search terms as “Autism”“loneliness disorder”“autism spectrum disorder”“parents”“caregiver”“medical decision making”, etc., qualitative studies on medical decision-making of ASD caregivers in the databases of PubMed, Web of Science, Cochrane Library, Embase, Scopus, CNKI.com, Wanfang Database, VIP database, and Chinese Biomedical Literature database were searched. The search was conducted from the inception of the databases to July 31, 2022, and the data was organized from August 1 to September 1, 2022. The literature quality was evaluated by two researchers according to the quality evaluation criteria for qualitative research at the Centre for Evidence-based Health Care, Joanna Briggs Institute, Australia. Pooled integration method was used to integrate the study results and evaluate the medical decision-making of children with ASD from the perspective of caregivers.Results:Seventeen studies were included, with two studies rated as quality grade A and fifteen studies rated as quality grade B. A total of 36 research findings were extracted. These findings were grouped into ten new categories based on similarities, which were further synthesized into three overarching results: the symptom-driven medical decision-making process, delays in medical decision-making due to individual, family, and societal factors, and the influence of personal experiences and multiple external pressures on medical decision-making.Conclusion:The factors that lead to the delay or promotion of medical decision of caregivers of children with ASD are complicated, and comprehensive intervention measures should be taken at individual, family and social levels to promote early medical diagnosis and intervention of the children with ASD.

Objective:To investigate the status quo of psychological contracts and influencing factors among members of the "1+N" family doctor teams in Shenzhen and to explore the impact of psychological contracts on job burnout.Methods:This cross-sectional study was conducted from September 30 to October 31, 2022 among 361 members of 92 family doctor teams from 92 community health service centers which provided family doctor team service in Shenzhen city. A self-designed general information questionnaire, an employee psychological contract questionnaire (including organizational responsibility and personal responsibility dimensions), and a job burnout scale (including emotional exhaustion, depersonalization, and personal accomplishment dimensions) were used in the study. T-tests, one-way ANOVA, Pearson correlation analysis, and multiple linear regression analysis were used to analyze the influencing factors of psychological contracts and job burnout.Results:Among 361 respondents, there were 299 females (82.8%) and 62 males (17.2%), and a higher proportion of general practitioners (37.5%, 129/361) and nurses (41.8%, 151/361). The total score of psychological contracts among the 361 respondents was (141.6±19.5), with organizational responsibility scoring (70.6±11.2) and personal responsibility scoring (71.0±9.3). On the job burnout scale, emotional exhaustion scored (17.89±6.82), depersonalization scored (6.51±2.54), and personal accomplishment scored (30.95±5.70). General practitioners scored lower in organizational responsibility and personal responsibility compared to other members ( F=7.341,3.119, all P<0.05), and higher in emotional exhaustion and depersonalization ( F=7.637, 2.415, all P<0.05). Members with≤5 years of work experience scored lower in personal responsibility and personal accomplishment ( F=3.656, 4.205, all P<0.05). Correlation analysis showed that scores of organizational responsibility and personal responsibility were negatively correlated with levels of emotional exhaustion and depersonalization ( r=-0.618, -0.526, all P<0.01), ( r=-0.404, -0.393, all P<0.01), and positively correlated with personal accomplishment ( r=0.500, 0.558, all P<0.01). Multiple linear regression analysis indicated that organizational responsibility negatively affected emotional exhaustion and depersonalization ( β=-0.554, -0.274, all P<0.01), and positively affected personal accomplishment ( β=0.172, P<0.05). Personal responsibility positively affected personal accomplishment ( β=0.404, P<0.01). Conclusions:The study demonstrates that general practitioners in family doctor teams in Shenzhen city have lower psychological contract levels and are more prone to emotional exhaustion and depersonalization; members with≤5 years of work experience have lower personal responsibility and accomplishment. The results indicate that enhancing organizational responsibility can reduce job burnout of members in family doctor teams.

Objective:To compare the efficacy and safety of red light and daylight photodynamic therapy in the treatment of facial common acne.Methods:From March 2019 to November 2019, 52 patients with facial common acne who received 5-aminolevulinic acid photodynamic therapy in the Department of Dermatology, Chongqing Hospital of Traditional Chinese Medicine were enrolled, including 34 males and 18 females, aged 18-35 years, with an average age of 23.2 years. A 5% concentration of 5-aminolevulinic acid was applied to the entire face, with the right side of the face being exposed to red light for 20 minutes and the left side to daylight for 2 hours. The treatment was administered once a week for a total of 4 sessions. After the treatment, the acne remission, adverse reactions, and patient satisfaction on both sides of the face were compared.Results:Compared with before treatment, the number of inflammatory and non-inflammatory lesions on both sides of the face in the enrolled patients decreased, and there was no significant difference in the clearance rate of skin lesions between the two sides [53.7% (28/52) vs 59.1% (31/52), χ 2=0.89, P>0.05]. The overall effective rate on the red light side was 88.5% (46/52), and 82.7% (43/52) on the daylight side, with no significant difference between the two (χ 2=0.38, P>0.05). In terms of adverse reactions, mild erythema was common, and it was less on the daylight side than on the red light side [34.6% (18/52) vs 19.2% (10/52), χ 2=5.98, P<0.05]. During the treatment period, the pain score on the daylight side decreased compared to the red light side [(7.6±2.3) vs (4.1±1.3), t=13.10, P<0.001]. Overall satisfaction with the daylight side was reported in 49 cases (94.2%), and with the red light side in 37 cases (71.2%), with the daylight side being higher than the red light side, and the difference was statistically significant (χ 2=9.60, P<0.05). Conclusion:Daylight photodynamic therapy is as effective as red light photodynamic therapy for common acne, but it produces fewer adverse reactions and higher patient satisfaction.

Objective To explore the impact of Suzi Jiangqi decoction(SJD)on the inflammatory state of patients with chronic obstructive pulmonary disease(COPD)through the regulation of the mitogen-activated protein kinase(MAPK)signaling pathway.Methods A total of 70 patients with stable COPD,treated from April 2023 to April 2024 at the Department of Traditional Chinese Medicine and Department of Respiratory outpatient clinic of Affiliated Jinhua Hospital,School of Medicine Zhejiang University were selected and randomly divided into observation group and control group,with 35 cases in each group.The control group received tiotropium bromide powder inhalation combined with budesonide/formoterol powder inhalation treatment,while the observation group was given SJD in addition to treatment of control group.After 12 weeks of treatment,the therapeutic effects were evaluated by assessing lung function,airway mucus hypersecretion,levels of interleukin(IL)-17,IL-6,and tumor necrosis factor(TNF)-α,CT quantitative parameters of the lung,as well as the expression levels of IL-17,p38MAPK,nuclear factor kappa-B(NF-κB)and C-X-C motif chemokine ligand 8(CXCL8)mRNA in sputum.Results Following treatment,there was a significant improvement in lung function indicators such as first second expiratory volume/forced vital capacity％,cough score,sputum difficulty score,sputum quality score,and sputum volume score for patients in both groups,with more pronounced improvements observed in observation group(P＜0.05).The levels of serum cytokines IL-17,IL-6 and TNF-αdecreased in both groups after treatment,with observation group showing a more significant reduction(P＜0.05).Additionally,the percentage ratio of low attenuation area to lung area(LAA％),emphysema index of lung CT in observation group significantly decreased after treatment(P＜0.05).Similarly,the expression levels of IL-17,p38MAPK,NF-κB and CXCL8 mRNA in sputum were also significantly reduced after treatment in observation group(P＜0.05).Conclusion SJD may improve lung function and inflammatory status in COPD patients by regulating the MAPK signaling pathway mediated by IL-17,demonstrating a positive therapeutic effect on the treatment of COPD.

Based on the resutls of literature review and interviews of experts, two rounds of Delphi surveys were conducted. The mean, importance ratio, coefficient of variation and coordination coefficient were used for assessment of survey from multiple perspectives, and finally form a framework model of factors affecting the efficacy of Tuina therapy. A total of 37 experts were selected for questionnaire surveys, the positive coefficients of experts' participatation in the first round and second round were 92.5% and 80.0%, respectively. The overall coordination coefficient in the second round is 0.68. The items were included into the consensus meeting if the importance ratio of items were equal to and more than 80%. After the expert consensus meeting, 22 items were included to form a framework model of factors affecting the efficacy of Tuina therapy, and summarized as 5 major influencing factors, including diagnostic factors, treatment factors, prognostic factors, patient factors, and doctor-patient communication. This framework can guide and help young Tuina practitioners to improve clinical efficacy. It is also clearly pointed out that the effect of Tuina for pain is not only related to disease diagnosis or manipulation, but also related to home exercise, health care, and doctor-patient communication.

Objective:To survey on the status quo of the role cognition and job burnout among family doctor team members in Shenzhen Futian district.Methods:A survey on the role cognition and job burnout of family doctor members was conducted in October 2022. One family doctor team was randomly selected from each of the 92 community health service centers in Futian district of Shenzhen city, and all members of the selected family doctor teams were included in the survey. The Chinese version of the Maslach Burnout Inventory-Human Services Survey was used in the study, and the influencing factors of role cognition and job burnout, as well as the impact of role cognition on job burnout were analyzed.Results:A total of 361 family doctor team members were included in the survey, The scores of the Role Ambiguity and Role Conflict Scale were (35.25±5.21) and (27.03±13.73), respectively. In the Occupational Burnout Scale, the scores of Emotional Exhaustion, Dehumanization, and Personal Achievement Scale were (17.89±6.82), (6.51±2.54), and (30.95±5.70), respectively. There were significant differences in role ambiguity and job burnout among family doctor team members with different ages, professions, and years of work ( P<0.05). Team members aged≤30, general practitioners, and working time ≤5 years had higher scores for role ambiguity, emotional exhaustion, dehumanization, and lower personal achievement ( P<0.05). The score of role ambiguity was negatively correlated with the degree of emotional exhaustion and dehumanization ( r=-0.544, -0.352), and positively correlated with personal achievement ( r=0.473). The score of role conflict was positively correlated with the degree of emotional exhaustion and dehumanization ( r=0.352, 0.376), and negatively correlated with personal achievement ( r=-0.440). Regression analysis showed that the role cognition was significantly associated with the emotional exhaustion, dehumanization, and personal achievement ( F=10.28-85.12, P<0.01). Conclusion:Active and effective measures should be taken to improve the role cognition and reduce job burnout of family doctor team members in primary health care institutions.
