Objective:To evaluate the impact of self-crosslinked hyaluronic acid (SCH) gel on endometrium recovery after artificial abortion.Methods:A multicenter, prospective randomized controlled trial was conducted across 18 hospitals from December 2021 to February 2023, involving 382 women who underwent artificial abortion. Participants were randomly allocated to receive either treatment with SCH gel (SCH group) or no treatment (control group) in a 1∶1 ratio. The primary outcome was endometrium thickness in 14 to 18 days after the first postoperative menstruation. Secondary outcomes included changes in menstrual volume during the first postoperative menstruation, menstruation resumption within 6 postoperative weeks, time to menstruation resumption, duration of the first postoperative menstruation, and incidence of dysmenorrhea.Results:Baseline characteristics of participants were comparable between the two groups (all P>0.05), with 95.3% (182/191) in SCH group and 92.7% (177/191) in the control group completed the study. The postoperative endometrial thickness in SCH group was significantly greater than that in the control group [(9.78±3.15) vs (8.95±2.32) mm; P=0.005]. SCH group also had significantly fewer participants with reduced menstrual volume [23 cases (12.6%, 23/182) vs 31 cases (17.5%, 31/177); P=0.038]. Although SCH group experienced less dysmenorrhea during the first postoperative menstrual period, this difference was not statistically significant [28.5% (51/179) vs 37.1% (65/175); P=0.083]. Outcomes were similar between SCH group and the control group regarding the proportion of participants who resumed menstruation within 6 weeks postoperatively, time to menstruation resumption, and duration of the first postoperative menstruation ( P=0.792, 0.485, and 0.254, respectively). No serious adverse events were observed during the study period, and no adverse events were attributed to SCH gel treatment. Conclusion:The application of SCH gel after artificial abortion is safe and might aid in the recovery of the endometrium.

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).

Objective    To explore coronary angiographic characteristics in patients with symptomatic recurrence after coronary artery bypass grafting (CABG). Methods    We performed a retrospective study of 997 patients with symptomatic recurrence after CABG in Beijing Anzhen Hospital from 2010 to 2020. There were 762 males and 235 females, with an average age of 62.41±8.70 years. Results    There was a high prevalence of risk factors like hypertension, diabetes and a history of smoking. Diseased arterial grafts accounted for 27.44% while saphenous vein graft 54.40%; 240 (24.07%) patients had all patent grafts. The main lesion characteristics of diseased grafts were chronic total occlusion lesions (79.57%). Most patients had more diseased native vessels after CABG than before. The type C coronary artery disease in native vessels relevant to ischemic area occurred in 674 (67.60%) patients; 525 (52.66%) patients with recurrent symptom after CABG had both diseased grafts and diseased native vessels. Conclusion     Graft status in patients with symptomatic recurrence after CABG is worse than we expected. The majority have newly developed lesions both in grafts and native vessels. Native vascular lesions will continue to progress after CABG.

Objective:To analyze the clinical effect of navigation-assisted cosmetic incision for reduction and internal fixation in treating unilateral B-type zygomatic fracture.Methods:A retrospective cohort study was performed on clinical data of 35 patients with unilateral type B zygomatic fracture treated from January 2018 to December 2019 in First Affiliated Hospital of Fujian Medical University. There were 20 males and 15 females at age range of 5-62 years [(38.7±11.3)years]. Navigation-assisted cosmetic incision for reduction and internal fixation was performed for 17 patients (navigation group), and empirical incision to reduction and internal fixation was performed for 18 patients (convention group). The length of bony zygomatic process (zygomatic process) and width of zygomatic temporal point (frontal width) of the bilateral zygomatic bone were measured on the horizontal axis of CT at 1 week after operation. The absolute values of the difference of bony zygomatic process degree and frontal bony width between affected side and the healthy side were compared between the two groups. The patients′ satisfaction and occurrence of complications such as lower eyelid ectropion, incision infection and facial nerve injury were compared between the two groups at half a year after operation.Results:All patients were followed up for 6-24 months [(9.3±1.2)months]. The absolute difference of bony zygomatic process was 0.60(0.25, 0.85) mm in navigation group, and was 0.75 (0.20, 1.98)mm in convention group ( P>0.05). The absolute difference of frontal bony width was (0.37±0.11)mm in navigation group, and was (2.47±0.63)mm in convention group ( P<0.01). Satisfaction rates by both objective evaluation and subjective evaluation in navigation group were better than that in convention group at half a year after operation (both P<0.05). Navigation group showed lower eyelid ectropion in 1 patient and incision infection in 1 patient. Convention group showed facial nerve injury in 1 patient and incision infection in 2 patients. There was no significant difference in the incidence of complications between navigation group [12%(2/17)] and conventional group [17%(3/18)] ( P>0.05). Conclusion:For unilateral type B zygomatic fracture, navigation-assisted cosmetic incision for reduction and internal fixation can more accurately restore the frontal width, and improve satisfaction rate as compared with empirical reduction and internal fixation.

Objective: To explore the association of TBX5 polymorphisms and environmental exposure index with susceptibility to oral cancer. Methods: A case-control study was conducted to collect 300 oral cancer patients hospitalized in the Department of Oral and Maxillofacial Surgery, the First Affiliated Hospital of Fujian Medical University from September 2010 to December 2016. A total of 445 non-tumor patients were selected as the control group. Questionnaires were used to collect the information of all subjects and 5 ml peripheral blood was collected to detect single nucleotide polymorphisms (SNPs) of the rs10492336 locus of TBX5 gene. According to the environmental exposure index score, subjects were divided into two groups, low risk group (0-2.31) and high risk group (2.32-11.76). To analyze the association of TBX5 gene rs10492336 SNPs, environmental exposure index and oral cancer and its interactions. Results: The age of all subjects in the case group and control group were (56.19±13.10) years and (54.56±12.48) years old. Compared with CC genotype, the OR (95%CI) values of the co-dominant genetic model AC genotype and the dominant genetic model AC+AA genotype were 0.69 (0.49-0.98) and 0.70 (0.51-0.97), respectively. Compared with the low risk group, the OR (95%CI) risk of oral cancer in the high risk group was 3.72 (2.55-5.43). The results of gene-environment interaction analysis showed that compared with the group with CC genotype and high risk of environmental exposure index, the OR (95%CI) value of oral cancer in the group with AC+AA genotype and low risk of environmental exposure index was 0.18(0.10-0.31). Furthermore there was a multiplicative interaction between rs10492336 SNPs and environmental exposure index (β=-0.405, P<0.001). Conclusion This study suggests that the TBX5 gene rs10492336 SNPs and environmental exposure index were associated with oral cancer. And there was a multiplication interaction between rs10492336 SNPs and environmental exposure index.

Objective: To explore the relationship between selenium and the risk for oral cancer. Methods: We performed a case-control study in 325 cases of newly diagnosed primary oral cancer from the First Affiliated Hospital of Fujian Medical University and 650 controls from the same hospital and community. Unconditional logistic regression and stratification analyses were used to explore the association between selenium and oral cancer. Adjusted OR and corresponding 95%CI were calculated. The analyses on multiple interactions between selenium and smoking or drinking status, and fruit or fish intake frequencies were conducted. Results: The level of serum selenium was 112.42 (80.98-145.06) μg/L in the case group, which was lower than 164.85 (144.44-188.53) μg/L in control group, the difference was statistical significant (P<0.01). There was a negative correlation between serum selenium level and the risk for oral cancer regardless of smoking and drinking status, and fruits and fish intake frequencies (P<0.05). There were multiple interactions between serum selenium level and smoking or drinking status, and fruit and fish intakes. Conclusions The high level of serum selenium is a protective factor for the incidence of oral cancer, and serum selenium has multiple interactions with smoking or drinking status, and fruit and fish intakes. Therefore, reducing tobacco use and alcohol consumption and increasing the intakes of fruit and fish can reduce the risk for oral cancer to some extent.

Objectives To investigate the efficacy of the shear wave velocity (SWV) based on acoustic radiation force impulse (ARFI) elastography in the differentiation of normal population with chronic kidney disease (CKD) and acute kidney injury (AKI) in middle aged and elderly patients.Methods Sixty-four middle aged and elderly patients referred to China-Japan Friendship Hospital and Zhejiang Provincial People's Hospital with AKI or CKD were enrolled in this study from February 2015 to December 2016 (kidney disease group).Among them,43 patients were CKD (CKD group),and 21 patients were AKI (AKI group,15 patients combined with prior CKD,6 patients without prior CKD).Twenty-nine middle aged and elderly healthy volunteers from China-Japan Friendship Hospital were enrolled at the same time (healthy control group).The SWV values of the renal middle pole cortex were acquired using the ARFI elastography.The differences of the kidney length,cortical thickness and SWV values among healthy control group,AKI and CKD group were compared by variance analysis.The LSD-t analysis was used for the advanced comparison between any two groups.The differences of cortical SWV values among healthy control group,AKI combined with prior CKD group,AKI without prior CKD group and CKD group were compared by variance analysis.The LSD-t analysis was used for the advanced comparison between any two groups.The receiver operating characteristic (ROC) curves of the cortical SWV values for diagnosing kidney disease was drawn.Results The mean cortical SWV values of healthy control group,AKI and CKD groups were (2.88±0.63),(2.42±0.83) and (2.06±0.72) m/s,respectively.The SWV values of AKI and CKD groups were significantly lower than that of healthy control group (t=2.158,P=0.033;t=5.234,P ＜ 0.001).The SWV values of CKD group were lower than that of AKI group,but there were no significant differences.The SWV values of AKI without previous CKD group and AKI combined with prior CKD group were (2.60±0.84) and (1.80±0.45) m/s,respectively.The SWV values of AKI combined with prior CKD group and CKD group were significant lower than that of healthy control group and AKI without prior CKD group (compared with healthy control group:t=2.916,P=0.004 and t=5.318,P ＜ 0.001;compared with AKI without prior CKD group:t=2.054,P=0.043 and t=-2.517,P=0.013).But there were no significant differences between AKI combined with prior CKD group and CKD group,so as to the AKI without prior CKD group and healthy control group.The cutoff value of cortical SWV for diagnosing kidney disease was 2.40 m/s,with an area under ROC curve was 0.767 (95％ CI 0.689-0.898,P=0.000).The sensitive and specificity were 57.1％ and 81.9％,respectively.Conclusions The SWV values of kidneys in middle aged and elderly CKD and AKI patients were significantly lower than those of apparently normal kidneys.The SWV values of AKI patients combined with prior CKD were lower than AKI patients without prior CKD.Determining cut-off SWV values based on ARFI elastography between normal and damaged renal parenchyma can help in the diagnosis of kidney disease in middle aged and elderly patients.

Objective: To evaluate the influence of oral hygiene on risk of oral cancer in non-smoking and non-drinking women. Methods: From September 2010 to February 2016, 242 non-smoking and non-drinking female patients with pathologically confirmed oral cancer were recruited in a hospital of Fuzhou, and another 856 non-smoking and non-drinking healthy women from health examination center in the same hospital were selected as control group. Five oral hygiene related variables including the frequency of teeth brushing, number of teeth lost, poor prosthesis, regular dental visits and recurrent dental ulceration were used to develop oral hygiene index model. Unconditional logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (95%CI). The area under the receiver operating characteristic curve (AUROC) was used to evaluate the predictability of the oral hygiene index model. Multivariate logistic regression model was used to analyze the association between oral hygiene index and the incidence of oral cancer. Results: Teeth brushing <2 twice daily, teeth lost ≥5, poor prosthesis, no regular dental visits, recurrent dental ulceration were risk factors for the incidence of oral cancer in non-smoking and non-drinking women, the corresponding OR (95%CI) were 1.50 (1.08-2.09), 1.81 (1.15-2.85), 1.51 (1.03-2.23), 1.73 (1.15-2.59), 7.30 (4.00-13.30), respectively. The AUROC of the oral hygiene index model was 0.705 9, indicating a high predictability. Multivariate logistic regression showed that the oral hygiene index was associated with risk of oral cancer. The higher the score, the higher risk was observed. The corresponding OR (95%CI) of oral hygiene index scores (score 1, score 2, score 3, score 4-5) were 2.51 (0.84-7.53), 4.68 (1.59-13.71), 6.47 (2.18-19.25), 15.29 (5.08-45.99), respectively. Conclusion Oral hygiene could influence the incidence of oral cancer in non-smoking and non-drinking women, and oral hygiene index has a certain significance in assessing the combined effects of oral hygiene.
