Objective:To compare the mid-term clinical effects of AngioJet rheolytic thrombectomy assisted catheter-directed thrombolysis (ART+CDT) with catheter-directed thrombolysis (CDT) in the treatment of acute deep venous thrombosis of lower extremities.Methods:Ninety-one patients admitted to the Department from Jan 2016 to Dec 2017 were placed with inferior vena cava filters and divided into ART+CDT group (30 cases)and CDT group (61 cases). Total urokinase dosge, thrombolytic time, operative cost, length of hospital stay, detumescence rate, thrombus clearance rate, cumulative patency rate of lower limb veins, Villalta score at 2 years and 5 years, thrombosis recurrence rate and chronic venous insufficiency quality of life questionnaire were compared between the two groups.Results:The success rate of surgery was 100% in both groups, there was no mortality. There were significant differences in the short-term postoperative outcomes between the two groups in terms of total dosage of urokinase, thrombolysis time, total cost of surgery, length of hospital stay, detumescence rate, venous patency scores before and after treatment, and venous patency rate (all P<0.05). For the mid- and long-term postoperative outcomes of 2 and 5 years, there were no significant differences in the incidence of PTS, recurrence rate of thrombus, chronic venous function scale, and cumulative patency rate at 2 years (all P>0.05). Conclusions:ART+CDT has a significant advantage over CDT alone in terms of early efficacy and early reopening of blood flow in patients. Both ART+CDT and CDT have a low incidence of PTS and a low recurrence rate of thrombus in the mid-term follow-up, and both have satisfactory performance in the mid- and long-term efficacy of interventional treatment of deep venous thrombosis of lower limbs.

Objective: To study the impact of sleep characteristics on myopia, among lower primary school students in Shanghai, so as to provide foundation for the prevention of the onset and development of myopia. Methods: A total of 636 students from the first and second grades of two primary schools in Jiading District, Shanghai, were selected through cluster random sampling for questionnaire surveys and ophthalmological examinations in October 2022. The Childrens Sleep Habits Questionnaire (CSHQ) was used to assess sleep quality at baseline. Ophthalmological examinations were conducted in October 2023(479), during which the students study time, screen time and outdoor activity time were monitored for twoweek, repeated twice. Generalized multivariable Logistic regression models and linear regression models were employed to examine the association between sleeprelated factors and myopia, as well as the strength of this association. Results: The baseline survey indicated a myopia prevalence of 18.58%, with 17.18% at followup. The average CSHQ total score was (51.58±4.44), and the average daily sleep duration was (9.43±4.84)h/d, with only 11.6% of participants meeting the recommended sleep sufficiency. Multivariable regression models indicated that insufficient sleep showed positive association with myopia (OR=1.64, 95%CI=1.05-2.56), while bedtime duration was significantly negative associated with myopia (OR=0.74, 95%CI=0.63-0.91, P＜0.05), adjusting for confounding factors. Inconsistency in bed rest time was a risk factor for myopia (OR=1.07, P<0.05), and the consistency of bed rest time, and wakeup time showed statistically significant correlations with SE (P<0.05). There was also statistically significant correlations between consistency in sleep time, bed rest time, and wakeup time with AL (P<0.05). Conclusions Insufficient sleep and bedtime duration are correlated with the onset and progression of myopia. It is critical to ensure sufficient sleep duration and regular sleep habits for children to reduce the occurrence of myopia in the primary school students.

Background::Triple-negative breast cancer (TNBC) is a type of highly invasive breast cancer with a poor prognosis. According to new research, long noncoding RNAs (lncRNAs) play a significant role in the progression of cancer. Although the role of lncRNAs in breast cancer has been well reported, few studies have focused on TNBC. This study aimed to explore the biological function and clinical significance of forkhead box C1 promoter upstream transcript (FOXCUT) in triple-negative breast cancer.Methods::Based on a bioinformatic analysis of the cancer genome atlas (TCGA) database, we detected that the lncRNA FOXCUT was overexpressed in TNBC tissues, which was further validated in an external cohort of tissues from the General Surgery Department of the First Affiliated Hospital of Nanjing Medical University. The functions of FOXCUT in proliferation, migration, and invasion were detected in vitro or in vivo. Luciferase assays and RNA immunoprecipitation (RIP) were performed to reveal that FOXCUT acted as a competitive endogenous RNA (ceRNA) for the microRNA miR-24-3p and consequently inhibited the degradation of p38. Results::lncRNA FOXCUT was markedly highly expressed in breast cancer, which was associated with poor prognosis in some cases. Knockdown of FOXCUT significantly inhibited cancer growth and metastasis in vitro or in vivo. Mechanistically, FOXCUT competitively bounded to miR-24-3p to prevent the degradation of p38, which might act as an oncogene in breast cancer. Conclusion::Collectively, this research revealed a novel FOXCUT/miR-24-3p/p38 axis that affected breast cancer progression and suggested that the lncRNA FOXCUT could be a diagnostic marker and therapeutic target for breast cancer.

ObjectiveTo investigate the association of lipid ratios with diabetes and pre-diabetes in residents aged 35-75 years in Changzhou City. MethodsA multistage whole-group random sampling method was used to survey permanent residents aged 35-75 years in Tianning and Wujin districts of Changzhou City， and the study data were obtained by questionnaires， physical examination and laboratory tests. The relationship between lipid ratios and diabetes and pre-diabetes was analyzed by dichotomous logistic regression method. ResultsThe prevalence of diabetes in the surveyed population in Changzhou was 18.69%， and the prevalence of pre-diabetes was 10.53%. In the total population， the risk of pre-diabetes was significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 68%， 93% and 38%， respectively； the risk of diabetes was also significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 105%， 149% and 78%， respectively. The risk of diabetes was also significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 105%， 149% and 78%， respectively. All three lipid ratios increased in women compared to men， leading to a stronger association with increased risk of diabetes and pre-diabetes. ConclusionLipid ratios TC/HDL-C， TG/HDL-C， and LDL-C/HDL-C were correlated with the risk of diabetes and pre-diabetes in people aged 35-75 years， with TG/HDL-C having the strongest association with diabetes and pre-diabetes， and is expected to be a key predictor for assessing the development of diabetes.

Objective:To compare the clinical effects of acute shortening-lengthening technique with antibiotic calcium sulfate-loaded bone transport technique for the treatment of segmental tibial defects after trauma.Methods:The clinical data of 58 patients with large tibial defects treated by Ilizarov technique in Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University from May 2014 to December 2019 were retrospectively analyzed. Thirty patients were treated by acute shortening-lengthening (group A), and they were divided into those who were successful in one-time shortening during operation (group A1) and those who needed gradual shortening after operation (group A2) according to different shortening conditions. And 28 patients by antibiotic calcium sulfate-loaded bone transport (group B). The external fixation time (EFT) and external fixation index (EFI) of the two groups were compared. Bone defect healing and limb functions were evaluated according to the Association for the Study and Application of the Method of Ilizarov (ASAMI) criteria. Complications were compared by Paley classification. The measurement data of normal distribution were expressed as ± s, and t-test was used for comparison between groups; the count data were expressed as n(%), and the chi-square test, Fisher exact probability method or Mann-Whitney U test were used for comparison between groups. Results:Patients were followed for(27.5±5.1)months. There was no significant difference in EFT, EFI, bone defect healing and limb functions between the two groups( P>0.05). The incidence of Grade-Ⅱ[41.2% (7/17)], Grade-Ⅲ [47.1% (8/17)] pin-tract infection in group A1 and Grade-Ⅱ[46.2% (6/13)], Grade-Ⅲ pin-tract [53.8% (7/13)] in group A2 was significantly higher than those in group B[14.3% (4/28)], [17.9% (5/28)] ( P<0.05). The number of complications per capita in group A1 [(1.4±0.3) times/case] and in group A2 [(1.5±0.3) times/case]was significantly higher than that in group B [(1.1±0.5) times/case]. Conclusions:Patients can be cured successfully by both acute shortening-lengthening and bone transport techniques. Compared with acute shortening-lengthening group, the complication incidence in antibiotic calcium sulfate-loaded bone transport group was lower, especially, the infection-related complications. Therefore, antibiotic calcium sulfate-loaded bone transport technique has a greater application prospect in patients with large segmental bone defects caused by infection or osteomyelitis.

Objective:To compare the clinical efficacy between bone transport technique combined with bone grafting plus internal fixation and simple bone transport technique in the treatment of large segmental bone defects at lower limbs after trauma.Methods:A retrospective study was conducted to analyze the clinical data of 42 patients with large segmental bone defects at lower limbs after trauma who had been treated at Department of Trauma Orthopaedics, Honghui Hospital Affiliated to Medicine College, Xi'an Jiaotong University from September 2015 to September 2019. The patients were divided into 2 groups according to the different methods of repairing bone defects. In group A of 18 patients subjected to bone transport combined with bone grafting plus internal fixation, there were 11 males and 7 females with an age of (35.2±10.3) years, and 12 tibial defects and 6 femoral defects; in group B of 24 patients subjected to simple bone transport, there were 15 males and 9 females with an age of (37.3±9.4) years, and 17 tibial defects and 7 femoral defects. The external fixation time (EFT), external fixation index (EFI), total cure time and complications were recorded and compared between the 2 groups. At the last follow-up, the Ennecking score for limb functional recovery (score/total score 30) and Self-rating Anxiety Scale (SAS) were used to evaluate respectively the functional recovery of the limbs and postoperative anxiety.Results:The 2 groups were comparable because there was no significant difference between them in preoperative general data or follow-up time ( P>0.05). There was no statistically significant difference in the number of surgeries between the 2 groups ( P>0.05). The EFT [(5.9±1.5) months], EFI [(0.45±0.09) months/cm], total treatment time [(16.2±2.4) months], Ennecking score for limb functional recovery (87.0%±8.6%), SAS score [(43.2±9.0) points], and complications per capita [(0.4±0.2) times/case] in group A were significantly better than those in group B [(15.3±4.2) months, (1.19±0.28) months/cm, (19.7±3.5) months, (77.3%±9.2%), (58.2±9.3) points, and (1.2±0.5) times/case] (all P<0.05). Conclusion:In the treatment of large segmental bone defects at lower limbs, compared with simple bone transport technique, bone transport technique combined with bone grafting plus internal fixation has advantages of shorter external fixation time and overall cure time, a lower rate of complications, and better functional recovery of the limbs.

Objective:To observe the effect of shift work on the stability of the circadian clock and insulin sensitivity in non-overweight/obese individuals with normal blood glucose, and explore underlying connection.Methods:Female shift working nurses in the Department of Blood Transplantation and non-shift working nurses in the Health Management Center in the First Affiliated Hospital of Zhengzhou University were divided into shift worker group (SW group) and non-shift worker group (NSW group). Serum inflammatory factors [interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α)], adipokines (adiponectin, leptin, chemerin, visfatin), and melatonin levels were measured using enzyme linked immunosorbent assay (ELISA). Realtime fluorescence quantitative PCR was performed to detect peripheral blood circadian clock genes circadian locomotor output cycles protein kaput(Clock) and brain and muscle ARNT-like protein 1(Bmal1). Cortisol and fasting insulin were measured by chemiluminescent microparticle immunoassay, and HbA 1C was measured by capillary electrophoresis. In addition, visceral fat area (VFA) was assessed with bioelectrical impedance analyzer, and mid-sleep time composite phase deviations (CPD) was calculated based on the International Physical Activity Short Questionnaire. Results:SW group had lower serum level of melatonin ( P=0.023) and higher cortisol ( P=0.001) than the NSW group, and altered mRNA expression of Clock and Bmal1 ( P=0.034, P=0.047). Fasting blood glucose and HbA 1C in the SW group, although in the normal range, had been higher than in the NSW group ( P=0.011, P=0.033). Although body mass index was normal in SW group, VFA had been higher than that of the NSW group ( P=0.010). And homeostasis model assessment for insulin resistance (HOMA-IR), IL-6, TNF-α, leptin, chemerin, and visfatin were significantly higher in the SW group than NSW group ( P=0.033, P=0.012, P=0.001, P=0.011, P=0.021, P=0.007). In addition, adjusting for body mass index and activity factors revealed a significant positive correlation between CPD and VFA ( r=0.434, P=0.049), inflammatory factors IL-6 ( r=0.514, P=0.017) and TNF-α ( r=0.700, P<0.001) and pro-inflammatory adipokines leptin ( r=0.473, P=0.030), chemerin ( r=0.439, P=0.047), visfatin ( r=0.521, P=0.015). Conclusion:Shift work can affect circadian clock, with increased visceral adiposity, pro-inflammatory adipokines, inflammatory factors and decreased insulin sensitivity in women without overweight/obese.

Comparison between groups of count data was conducted using the chi-square test or Fisher exact probability. Results:All 46 patients were followed up for to (19.17±2.79) months. All fractures healed after operation. There was no significant difference in operation time, range of motion, patient satisfaction, MEPS and DASH scores among the two groups( P>0.05). The time of returning to work was (8.47±2.13) weeks in the double plate group and (9.78±1.98) weeks in the single plate group, and the difference was statistically significant ( P< 0.05). There were 9 cases of internal fixation due to soft tissue stimulation, 1 cases in double plate group and 8 cases in single plate group, and the difference was statistically significant ( P<0.05). Conclusions:Compared with anatomical locking plate, the treatment of olecranon fracture with double mini locking plate can effectively reduce soft tissue stimulation and promote patients to return to work early, and the operation time is not significantly prolonged, and the biomechanical advantage is obvious, the clinical effect is satisfactory and the postoperative function is good, so it is an effective treatment.

Objective:To introduce our modified hybrid bone transport technique using hindfoot arthrodesis nails combined with antibiotic-loaded calcium sulfate by comparison with conventional bone transport in the treatment of distal tibial osteomyelitis with bone defects involving the articular surface.Methods:The clinical data of 34 patients were retrospectively analyzed who had been treated at Department of Orthopaedics, Honghui Hospital for distal tibial osteomyelitis with bone defects involving the articular surface from September 2014 to September 2019. They were divided into 2 groups according to their way of repairing bone defects. In the modified group of 14 cases subjected to the treatment using the modified hybrid bone transport technique, there were 9 males and 5 females, with an age of (39.4±7.3) years. In the conventional group of 20 cases subjected to the treatment using conventional bone transport technique, there were 12 males and 8 females, with an age of (41.2±6.6) years. The external fixation time (EFT), external fixation index (EFI), self-rating anxiety scale (SAS) were recorded and compared between the 2 groups. Healing of bone defects and function were evaluated at the last follow-up according to the criteria of Association for the Study and Application of the Method of Ilizarov (ASAMI) and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-posterior foot score, respectively. Complications were recorded according to the Paley classification.Results:There was no significant difference in the general data between the modified group and the conventional group, showing they were comparable ( P>0.05). Thirty-four patients were followed up for 18 to 32 months (average, 27 months) after operation. The modified group had significantly shorter EFT [(3.9±1.6) months] than the conventional group [(9.8±2.2) months], and significantly lower EFI [(0.48±0.09) months/cm] than the conventional group [(1.42±0.32) months/cm] ( P<0.05). The SAS [(48.1±4.7) points] in the modified group was significantly lower than that in the conventional group [(61.2±6.2) points], and the number of complications per capita in the former [(0.8±0.4)/case] was significantly smaller than that in the latter [(1.42±0.32)/case] ( P<0.05). There were no significan differences in the healing of bone defects or AOFSA ankle-posterior foot score ( P>0.05). In the modified group and the conventional group, respectively, 13 versus 12 patients were satisfied while 1 versus 8 patients unsatisfied, 1 versus 8 patients had grade-Ⅱ infection while 13 versus 12 patients did not, and 1 versus 9 patients had grade-Ⅲ infection while 13 versus 11 patients did not. There were significant differences between the 2 groups in the above indexes (all P<0.05). Conclusion:In the treatment of distal tibial osteomyelitis with bone defects involving the articular surface, compared with conventional bone transport technique, our modified hybrid bone transport technique using hindfoot arthrodesis nails combined with antibiotic-loaded calcium sulfate may lead to better clinical efficacy due to the advantages of shorter external fixation time, lower external fixation index and fewer complications.
