ABSTRACT

Objective@#To understand health literacy and associated factors of freshmen from Jiangsu Province, and to provide reference for youth health education.@*Methods@#From 2017 October to 2018 October, a total of 15 602 college freshman were randomly selected from 20 universities in Jiangsu Province via stratified cluster sampling method. Structural questionnaires were used to investigate the status of health literacy. The χ 2 test and multivariate Logistic regression model were used to analyze the influencing factors of health literacy.@*Results@#The health literacy level of college freshmen from Jiangsu Province was 20.2%, among which the literacy levels of knowledge, behavior and skills were 23.0%, 30.7% and 31.5% respectively. The literacy levels of the six public health issues, including safety and first aid, scientific health attitude, knowledge of prevention and treatment of infectious diseases, health information, basic health care, and prevention and treatment of chronic diseases, from high to low, were 72.8%, 58.7%, 28.5%, 28.2%, 20.3% and 15.9%, respectively. Multivariate Logistic regression analysis has showed that students from undergraduate colleges(OR=2.77, 95%CI=2.47-3.11), urban areas(OR=1.20, 95%CI=1.07-1.34), or southern Jiangsu regions(OR=1.10, 95%CI=1.00-1.22), being the only child(OR=1.13, 95%CI=1.03-1.25), higher maternal education level (OR=1.53, 95%CI=1.30-1.79), having both parents(OR=1.16, 95%CI=1.00-1.34), reported higher level of health literacy.@*Conclusion@#The three aspects and six dimensions of health literacy of college freshmen were unbalanced. Health literacy is a shared function of multiple factors including society, family, and individuals. It is essential to promote health education through more efforts on key issues, in order to effectively elevate the health literacy level of adolescent students.

ABSTRACT

Purpose@#This study aimed to explore the role of the long non-coding RNA (lncRNA) RNA component of mitochondrial RNAase P (RMRP) in sepsis-induced acute kidney injury (AKI). @*Materials and Methods@#Venous blood was collected from septic patients and healthy people. C57BL/6 mice who underwent cecal ligation and puncture (CLP) were used as in vivo models of septic AKI. Lipopolysaccharide (LPS)-induced HK-2 cells were employed as in vitro models of AKI. Flow cytometry analysis was conducted to detect cell apoptosis. Enzyme-linked immunosorbent assay and Western blot assays were used to detect levels of pro-inflammatory cytokines. @*Results@#RMRP was upregulated in sera from patients with AKI and in LPS-induced cells. Knockdown of RMRP inhibited cell apoptosis and reduced production of inflammatory factors in LPS-induced cells, as well as alleviated AKI in CLP mice. RMRP facilitated inflammation by activating NACHT, LRR, and PYD domains-containing protein 3 (NLRP3) inflammasome. We found that microRNA 206 (miR-206) binds with and is negatively regulated by RMRP: miR-206 directly targets the 3’ untranslated region of DEAD-box helicase 5 (DDX5) and negatively regulates DDX5 expression. By binding with miR-206, RMRP upregulated DDX5 expression. Rescue assays revealed that overexpression of DDX5 counteracted the effect of RMRP inhibition on cell apoptosis and inflammatory response in LPS-induced cells. @*Conclusion@#The lncRNA RMRP contributes to sepsis-induced AKI through upregulation of DDX5 in a miR-206 dependent manner and through activation of NLRP3 inflammasome. This novel discovery may provide a potential strategy for treating AKI.

ABSTRACT

Objective@#: Shunt infection is a common complication while treating hydrocephalus. The antibiotic-impregnated shunt catheter (AISC) was designed to reduce shunt infection rate. A meta-analysis was conducted to study the effectiveness of AISCs in reduction of shunt infection in terms of age, follow-up time and high-risk patient population. @*Methods@#: This study reviewed literature from three databases including PubMed, EMBASE, and Cochrane Library (from 2000 to March 2019). Clinical studies from controlled trials for shunt operation were included in this analysis. A subgroup analysis was performed based on the patient’s age, follow-up time and high-risk population. The fixed effect in RevMan 5.3 software (Cochrane Collaboration) was used for this meta-analysis. @*Results@#: This study included 19 controlled clinical trials including 10105 operations. The analysis demonstrated that AISC could reduce the infection rate in shunt surgery compared to standard shunt catheter (non-AISC) from 8.13% to 4.09% (odds ratio [OR], 0.48; 95% confidence interval [CI], 0.40–0.58; p=0.01; I2=46%). Subgroup analysis of different age groups showed that AISC had significant antimicrobial effects in all three groups (adult, infant, and adolescent). Follow-up time analysis showed that AISC was effective in preventing early shunt infections (within 6 months after implant). AISC is more effective in high-risk population (OR, 0.24; 95% CI, 0.14–0.40; p=0.60; I2=0%) than in general patient population. @*Conclusion@#: The results of meta-analysis indicated that AISC is an effective method for reducing shunt infection. We recommend that AISC should be considered for use in infants and high-risk groups. For adult patients, the choice for AISC could be determined based on the treatment cost.

ABSTRACT

OBJECTIVE@#To explore the correlation between DSG2, TTN and GATA4 genes and Brugada syndrome in Henan Province of China.@*METHODS@#From February 2017 to February 2019, 100 patients with Brugada syndrome and 100 healthy individuals were selected as the study and the control groups, respectively. Electrocardiogram and echocardiography were carried out, and peripheral blood samples was collected. Coding regions of DSG2, TTN and GATA4 genes were amplified by PCR and sequenced. The results were compared with standard sequences from GenBank.@*RESULTS@#Electrocardiogram showed that all patients from the study group had ventricular arrhythmia, 87 cases (87%) presented ventricular tachycardia (VT), 84 cases (84%) presented T wave inversion, and 51 cases (51%) presented Epsilon wave. Echocardiography showed that the right ventricle in the study group was enlarged with the inner diameter of the right ventricle being (40.0±13.3) mm, and the right ventricle showed various degree of abnormal systolic function. The enlargement of right atrium accounted for 64%, and the involvement of the left ventricle accounted for 27%. The right ventricular diameter and left ventricular diastolic diameter of the study group were significantly greater than those of the control group (P< 0.05). DNA sequencing showed that 60 patients carried DSG2 gene variants, among which 18 had missense variant of exon 8. Fifty patients carried TTN gene variants, including 8 in the A-band domain and 3 in the I-band domain. Twenty patients carried 3 variants of the GATA4 gene.@*CONCLUSION@#Variants of the DSG2, TTN and GATA4 genes in Henan region are correlated with the onset of Brugada syndrome.

ABSTRACT

ObjectiveTo investigate the role of coagulation function parameters and platelet indices in thrombotic events in patients with hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF). MethodsA total of 56 patients with HBV-ACLF who were hospitalized in The First Affiliated Hospital of Soochow University from January 2015 to December 2019 were enrolled and divided into thrombotic complication (TC) group with 24 patients and non-thrombotic complication (NTC) group with 32 patients. A retrospective analysis was performed for their general clinical data on admission, and the patients were observed in terms of the changes in coagulation function, platelet count (PLT), and the platelet function-related index mean platelet volume (MPV) on days 1-7 after admission. The t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. A repeated measures analysis of variance was used to compare coagulation markers within and between groups at different time points. ResultsOn admission, the TC group had a significantly younger age than the NTC group [31.5 (29.0-34.0) years vs 48.5 (36.0-50.7) years, Z=-2.637, P=0.008]. On the day of admission, there was no significant difference in MPV between the TC group and the NTC group (P >0.05), while on days 2-7 after admission, there was a significant difference in MPV between the two groups (t=-2.696、-2.742、-2.894、-4.174、-3.945、-4.716,all P <0.01). In the TC group, MPV reached the peak value on day 5 of admission, with a mean value of 13.90±1.12 fl, which was higher than the range of normal values. On admission, all patients had a mean prothrombin time (PT) of 28.8±7.2 s, a mean activated partial thromboplastin time (APTT) of 50.5±8.7 s, and a mean international normalized ratio (INR) of 2.6±0.7, which were higher than normal values; all patients had a mean fibrinogen (Fb) level of 1.16±0.3 g/L and a mean PLT of (107.7±26.5)×109/L, which were lower than normal values. There were no significant differences in PT, APTT, Fb, INR, and PLT between the TC group and the NTC group (all P >0.05). ConclusionCoagulation disorder in patients with liver failure is more of a low-equilibrium state, which is complex and heterogeneous and requires individualized treatment. For patients with HBV-ACLF, the development of thrombotic events may be more associated with platelet function than PLT or conventional coagulation markers.

ABSTRACT

ObjectiveTo investigate the value of interleukin-32 (IL-32) combined with Model for End-Stage Liver Disease (MELD) in predicting the prognosis of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (HBV-ACLF). MethodsA total of 92 patients with HBV-ACLF who were hospitalized in The First Affiliated Hospital of Soochow University from January 2015 to December 2018 were enrolled, and according to the follow-up results at 3 months after diagnosis, the patients were divided into survival group with 40 patients and death group with 52 patients. ELISA was used to measure the serum level of IL-32. Clinical data of the patients were collected, including age, sex, underlying diseases, major complications, white blood cell count (WBC), platelet count (PLT), hematocrit (HCT), total bilirubin (TBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (Alb), serum creatinine (SCr), prothrombin time (PT), international normalized ratio (INR), and HBV DNA. The t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups; a Pearson correlation analysis was performed for IL-32 and other variables; a binary logistic regression analysis was performed to investigate the independent risk factors for the prognosis of patients with HBV-ACLF. The receiver operating characteristic(ROC) curve(AUC) was used to evaluate the value of IL-32 combined with MELD score in predicting the prognosis of patients with HBV-ACLF. The normal Z test was used for comparison of AUC. ResultsThere were significant differences between the two groups in HCT, PLT, TBil, SCr, PT, INR, HBV DNA, IL-32, and MELD score (all P<0.05). IL-32 was positively correlated with TBil (r=0.952, P<0.001) and MELD score (r=0850, P<0.001). IL-32 (odds ratio [OR]=1.137, 95% confidence interval [CI]: 1040-1243, P=0.005) and MELD score (OR=1.055, 95% CI: 1.001-1.109, P=0.025) were independent risk factors for the death of HBV-ACLF patients. IL-32 combined with MELD score had the highest value in predicting the prognosis of patients with HBV-ACLF (AUC=0.992, 95% CI: 0.981-1000), with a significantly higher AUC than IL-32 (0.992 vs 0.984, Z=2.265, P<0.05) and MELD score (0.992 vs 0877, Z=3182, P<0.05). ConclusionBoth IL-32 and MELD score can predict the prognosis of patients with HBV-ACLF, and the combination of these two indicators has a better predictive value.

ABSTRACT

Objective:To evaluate the role of esophagogastric junction contractile index (EGJ-CI) in distinguishing patients with refractory gastroesophageal reflux disease (RGERD) from functional heartburn (FH).Methods:From March 2014 to January 2018, 82 patients with proton pump inhibitor (PPI) refractory heartburn and/or regurgitation, who visited the Outpatient Department of Gastroenterology at The First Affiliated Hospital with Nanjing Medical University were enrolled, among them 50 patients with RGERD (RGERD group) and 32 patients with FH (FH group). EGJ-CI of RGERD group and FH group were compared. The sensitivity and specificity of EGJ-CI to distinguish RGERD from FH patients. The correlation between EGJ-CI and high resolution esophageal manometry parameters, baseline impedance level and 24 h impedance-pH monitoring parameters were analyzed. Mann-Whitney U test, receiver operator characteristic curve analysis and Spearman correlation analysis were used for statistical analysis. Results:The EGJ-CI of RGERD group was lower than that of FH group (25.8 mmHg·cm (14.1 mmHg·cm, 35.9 mmHg·cm)(1 mmHg=0.133 kPa) vs. 39.2 mmHg·cm (23.0 mmHg·cm, 60.8 mmHg·cm)), and the difference was statistically significant ( Z=-2.833, P=0.005). When the cut-off value of EGJ-CI was 35.8 mmHg·cm, the sensitivity and specificity to distinguish RGERD from FH were 76.0% and 62.5%, respectively; area under the curve was 0.69 (95% CI 0.57 to 0.81). EGJ-CI was positively correlated with lower sphincter resting pressure, integrated relaxation pressure, distal contractile integral, distal esophageal pressure, and mean nocturnal baseline impedance ( r=0.812, 0.631, 0.451, 0.490 and 0.401, all P<0.01). EGJ-CI was negatively correlated with DeMeester score, acid exposure time, total reflux episodes, acid reflux episodes, long reflux episodes and longest reflux time ( r=-0.363, -0.372, -0.346, -0.318, -0.300 and -0.291, all P<0.01). Conclusions:EGJ-CI can help to distinguish patients with FH from RGERD.

ABSTRACT

Objective:To investigate the pathogenic gene locus and prenatal genetic diagnosis of 54 families with oculocutaneous albinism (OCA).Methods:This retrospective study enrolled 54 OCA probands and their families from Gansu Province Maternal and Child Health Care Hospital from May 2014 to May 2020. TYR gene variation screening was performed on the probands by Sanger sequencing. Those with negative results were analyzed by high-throughput sequencing, and further verification was performed on their parents by Sanger sequencing. Among the 54 families, 15 ml amniotic fluid were collected from 16 women at 18-21 gestational weeks in their subsequent pregnancy. Sanger sequencing combined with short tandem repeats sequence for linkage analysis were performed for genetic analysis. All data were analyzed using descriptive statistical analysis. Results:Out of the 54 OCA probands, 48 were diagnosed as OCA1, five were OCA2 and one was OCA4 based on the Sanger sequencing and high-throughput sequencing detection. A total of 26 different variation sites were involved in the 48 OCA1 probands, including 15 missense mutations, five nonsense mutations, three splicing mutations, and three frame-shift mutations, among which, c.929insC (29%, 28/96) was the most frequent mutation, followed by c.896G>A (11%, 11/96), c.832C>T (8%, 8/96) and c.703T>C (5%, 5/96). The diagnosis was confirmed in all 16 fetuses in the 16 families that underwent prenatal diagnosis. Five of them were affected and their mothers chose to terminate the pregnancies, the other 11 pregnancies continued to delivery, including seven heterozygous carriers and four fetuses without the same pathogenic allele as the proband. Maternal contamination was excluded in all prenatal samples using short tandem repeat for linkage analysis. All 11 children were in good health during telephone follow-up one month after birth. Postnatal validations were consistent with the prenatal tests.Conclusions:Genetic diagnosis could accurately identify various types of OCA and help to provide prenatal diagnosis and fertility consultation for subsequent pregnancies.

ABSTRACT

Objective:To explore the regulatory role of exosomes in calcification of rat vascular smooth muscle cells (VSMC) induced by high phosphorus.Methods:VSMC (A7r5 cells) were cultured in vitro and randomly divided into three groups: normal phosphorus group (0.9 mmol/L), high phosphorus group (2.6 mmol/L) and high phosphorus exosomes induction group (i.e. the exosomes extracted from high phosphorus group were added to VSMC in normal culture). Until the 7th day of culture, the culture medium of normal phosphorus group and high phosphorus group obtained during the change of cell culture medium was collected, and the precipitate was obtained by ultracentrifugation and suspended by phosphate buffered saline. The protein content of the precipitate was determined by BCA protein quantitative method. The precipitates were identified. The structure and size of exosomes were observed by transmission electron microscope. The exosomes marker proteins tumor susceptibility gene 101 protein (TSG101) and CD9 were detected by Western blotting. The miRNA in exosomes was extracted, and the expression of related miRNA (miR-30b, miR-204, miR-211) were observed by real-time quantitative PCR. After 7 days of cultivation, the exosomes uptake process of VSMC in high phosphorus exosomes induction group was observed. The calcium deposition was detected by Alizarin stain, and the calcium content was detected by O-cresol complex copper. The content of alkaline phosphatase was detected by colorimetry. The protein expression of Runx2 was quantified by Western blotting. Results:(1) The precipitate obtained by ultracentrifugation of the cell culture fluid was identified as exosomes by electron microscopy morphology. Western blotting confirmed that the expression of the exosomal marker proteins TSG101 and CD9 were positive. (2) The exosomes were rich in miRNAs. The expression of miR-30b, miR-204, miR-211, which negatively regulated the transcription of Runx2, was significantly down-regulated in the high-phosphorus group compared with the normal group ( P<0.05). (3) After culturing rat VSMC with high phosphorus for 7 days, calcium salt deposition was obvious. Compared with the normal phosphorus group, calcium content and alkaline phosphatase activity were significantly increased (both P<0.05), and Runx2 expression was also significantly increased ( P<0.05). (4) Added the obtained high-phosphorus exosomes to the normal cultured VSMC, the exosomes could be taken up by VSMC and successfully induced VSMC calcification. The levels of cell calcification indicators and Runx2 expression were significantly increased. Conclusions:High phosphorus induces calcification of VSMC and promotes the increase of Runx2 expression. The mechanism may be realized by releasing exosomes from VSMC to transmit cell signals.

ABSTRACT

Objective:To investigate the effect of hemoglobin (Hb) volatility on cardiovascular prognosis in peritoneal dialysis (PD) patients.Methods:Retrospective cohort study was designed. Patients undergoing stable PD for more than 3 months and followed up regularly for at least 1 year were enrolled from May 1, 2013 to October 31, 2014 in the General Hospital of Ningxia Medical University. According to the Hb variation based on the mean changes in Hb standard deviation at 1 month, 3 months, 6 months, 12 months over baseline Hb, all patients were divided into low volatility group (≤10 g/L), moderate volatility group (>10-20 g/L) and high volatility group (>20 g/L), and baseline information were compared among these groups. Kaplan-Meier survival analysis and Cox regression equation were used to analyze the relationship between Hb variation and cardiovascular mortality and all-cause mortality. Besides, the patients were divided into qualified group (Hb≥110 g/L) and substandard group (Hb<110 g/L) by the Hb level at the study endpoint (cardiovascular death and all-cause death) according to KDIGO guidelines and relevant literature. Cox regression analysis was used to analyze the relationship between Hb variation and cardiovascular death in qualified group or substandard group. Multivariate linear regression analysis was used to analyze the related factors of Hb fluctuation in PD patients.Results:A total of 267 patients were enrolled. There were 160 males (59.93%) in this study. The age was (52.66±13.72) years old, and the median dialysis age was 37(21, 61) months. The patients' baseline Hb (before dialysis) was (80.16±14.89) g/L and at the end of the study Hb was (105.34±22.08) g/L. Body mass index and baseline Hb levels in the high volatility group were lower than those in low volatility group and moderate volatility group (all P<0.05). Both moderate and high volatility groups had lower estimated glomerular filtration rate than that in low volatility group, and high volatility group had higher urea nitrogen level than that in low volatility group (all P<0.05). The amount of erythropoietin usage in the high volatility group was higher than that in moderate volatility group ( P<0.05). The Kaplan-Meier survival analysis results showed that there was no significant difference in survival rate for all-cause death (Log-rank χ2=0.735, P=0.693) and cardiovascular death (Log-rank χ2=2.961, P=0.228) in different Hb volatility groups. Cox regression analysis showed that after adjusting for age, sex, serum creatinine, and blood albumin, higher Hb volatility was associated with a lower risk of cardiovascular death ( HR=0.972, 95% CI 0.947-0.999, P=0.040). After adjusting for related confounding factors, higher Hb volatility was still a protective factor for cardiovascular death in the substandard group ( HR=0.946, 95% CI 0.903-0.992, P=0.022), but there was no significant correlation between Hb fluctuation and all-cause death. Multivariate linear regression analysis results showed that the fluctuation level of Hb was positively correlated with Kt/V ( B=4.682, 95% CI 2.480-6.884, P<0.001) and erythropoietin dosages ( B=0.001, 95% CI 0-0.001, P=0.003), and negatively correlated with baseline Hb ( B=-0.554, 95% CI -0.651--0.457, P<0.001). Conclusions:High Hb variability is a protective factor for cardiovascular death in PD patients with lower Hb level (substandard Hb). Adopting a reasonable program to correct anemia timely to reach the standard level has a greater impact on reducing risk of cardiovascular death in PD patients than Hb variation in anemia treatment.

ABSTRACT

Objective:To establish a 10-year comparison table of cerebrovascular function score and first stroke risk, and to provide a new method for screening of high-risk population of stroke.Methods:In the beginning of 2003, a cohort for studing stroke risk factors in those aged 40 years and over was established in a community of Shanghai by cluster sampling. The common risk factors of stroke were investigated with a unified questionnaire, and the cerebrovascular function (cerebral vascular hemodynamic indexes, CVHI) was measured. The baseline study was completed from April to June 2003 and December 2004 to January 2005, respectively. The incident of first stroke and all cause of death were followed up year by year. The follow-up period was up to December 31, 2014. The 10-year incidence of first stroke was calculated according to the baseline score of cerebrovascular function, and the score-risk control table was established to estimate 10-year first stroke risk in each score group. The role of cerebrovascular function score in stroke was also estimated.Results:The follow-up term of 10 565 participants was (10.26±2.00) years, and 350 patients had first stroke during the follow-up. The trend 10-year incidence of first stroke both in men and women was significantly increased with the decrease of the score of cerebrovascular function (trend χ2=296.125, P<0.01). As the 10-year risk of first stroke was higher than 5% and higher than 10%, the corresponding CVHI score was lower than 70 and 40 points in males and lower than 30 and 20 points in females. When the scores of cerebral vascular function were divided by every 25 points, incidence of first stroke in each group from top to bottom was 1.9%, 4.7%, 10.8%, 15.2% in males and 1.6%, 4.4%, 4.8%, 11.4% in females, respectively. As compared to the top, the relative risk (95% CI) of first stroke in the lower groups was 2.61(1.67-4.07), 6.46(4.22-9.89), 9.74(6.53-14.52) for males and 2.82(1.93-4.12), 3.15(1.99-4.99), 8.12(5.65-11.68) for females, respectively. Multivariate analysis showed that the factors being selected into the regression equation were cerebrovascular function score, age, hypertension history, stroke family history and smoking history, among which the role of cerebrovascular function score was the strongest. Conclusion:The risk of first stroke increases significantly with the decrease of cerebrovascular function score, which can be used to assess the 10-year risk of first stroke.

ABSTRACT

Rivaroxaban is one of the new oral anticoagulants (NOAC) for preventing stroke and systemic embolism in patients with non-valvular atrial fibrillation. It has clear pharmacokinetic parameters, stable plasma concentration, less drug-drug interaction and higher compliance of patients. However, the discrepancy of pharmacokinetics between individuals and drug-induced hemorrhage events frequently occur clinically, therefore the association of gene polymorphism with drug metabolism has become a research hotspot. This article reviews the research progress on pharmacokinetic characteristics of rivaroxaban and its relationship with gene polymorphism, to provide a reference for the individualized rational use of rivaroxaban.

ABSTRACT

Objective:To analysis the impact of public health emergencies on mood fluctuations of depression and the related factors in the elderly in Shanghai, in order to provide a new evidence for early psychological intervention.Methods:A cross-sectional survey was conducted among 983 elderly in the Department of Geriatrics of Xinhua Hospital Affiliated to Shanghai Jiaotong University and two communities in Changning and Hongkou Districts of Shanghai by using a self-compiled social life questionnaire and Geriatric Depression Scale(GDS-30)during corona virus disease(COVID)-19 outbreak from 1 February to 15 February 2020.The mood fluctuations of depression and the related influencing factors were analyzed by comparing the current GDS-30 scores with the scores within previous six months.Results:Of 983 questionnaires, 867 were valid.The incidence of mild fluctuations of depression was increased from 20.9%(181/867)to 27.2%(235/867)during the public health emergencies( P<0.05), with 3 cases of newly emerged severe depression.The GDS-30 scores were higher during the public health emergencies than before the emergencies(9.88±3.85 vs.7.67±3.54, P<0.05). The four risk factors inducing fluctuations of depression in the elderly were the number of coexisted chronic diseases ≥2( P=0.036), the lack of visits or communication from families( P=0.015), the family members exposing a risk to COVID-19( P<0.01), and the daily viewing of epidemic news more than 4 h( P=0.023). Linear regression analysis showed that cough, sore throat, dizziness, sleep disturbance and dyspnea were significantly related to the aggravation of depression(based on the increase of GDS-30 score)( P<0.05). Conclusions:Public health emergencies may exacerbate depression in the elderly.They are more likely to experience the aggravation of depression when they suffer from multiple chronic diseases, lack the child visits or communications, have the family members exposing a risk to COVID-19 and pay excessive attention to the epidemic.

ABSTRACT

Objective:To summarize the age, gender difference, cause, location, time, treatment and prognosis of femoral intertrochanteric fracture complicated with pseudoaneurysm, and analyze the influence of different treatment methods on the occurrence of femoral intertrochanteric fracture complicated with pseudoaneurysm.Methods:Using the method of systematic literature review, a total of 76 literatures were retrieved from multiple databases at home and abroad, and 45 literatures were screened out through the second screening of title, abstract and full text. The patients with intertrochanteric fracture complicated with pseudoaneurysm were selected as the research objects, and the duplicate cases were deleted; the age, gender, onset age, etiology, location, treatment and prognosis of the disease were retrospectively analyzed.Results:A total of 54 cases of femoral intertrochanteric fracture related pseudoaneurysms were selected from 45 literatures, including 25 males and 27 females, and 2 cases had no gender; aged from 43 to 94 years old, and 4 cases were younger than 60 years old, 6 between 61 and 70, 17 between 71 and 80, and 25 between 81 and 90. Forty-five cases occurred in deep femoral artery, 3 cases in superficial femoral artery, 1 case in superior gluteal artery, 1 case of medial circumflex artery, 1 case of lateral circumflex femoral artery, 1 case of femoral artery, and 2 cases of unknown location. The occurrence time of pseudoaneurysm: 17 cases within 1 week after fracture, 8 cases from 1 week to 3 weeks, 19 cases from 3 weeks to 3 months, 2 cases more than 3 months, and 8 cases unknown. The causes of pseudoaneurysm: among the 54 patients, 41 cases had definite causes, including 21 cases of vascular injury caused by fracture block; 20 cases of iatrogenic injury, of which the incidence of direct injury of blood vessels by screw or drill was the highest, accounting for 55% (11/20). Twenty-two cases were treated with vascular embolization, 10 cases with surgical sutures, 8 cases with surgical ligation, 4 cases with resection of pseudoaneurysm, 5 cases with covered stent, and 4 cases with thrombin injection. There were 42 cases who had follow-up data, and no recurrence and other complications were found during the follow-up period.Conclusion:The peak age of femoral intertrochanteric fracture complicated with pseudoaneurysm was 71-90 years old. The incidence of femoral intertrochanteric fracture complicated with pseudoaneurysm was more often within 1 week after fracture and 3 weeks to 3 months after fracture, due to fracture fragments and iatrogenic vascular injury caused by the location of the profundus femoris artery. Treatment options include vascular embolization, surgical ligation, suture or resection of pseudoaneurysm, covered stent and thrombin injection, and the prognosis is generally good.

ABSTRACT

Objective:To compare the difference of LLD (leg length discrepancy) between robot-assisted and conventional methods of total hip arthroplasty (THA).Methods:Data of 38 patients who had THA performed by robot-assisted or conventional methods from January 2019 to May 2020 were retrospectively analyzed. There were 38 cases (54 hips) in robot-assisted THA group (robot group) with 18 males and 20 females (age 53.5±13.6 years, BMI 26.2±3.4 kg/m 2), and there were 21 cases (32 hips) with osteonecrosis of the femoral head, 17 cases (22 hips) with Crown typeⅠandⅡdevelopmental dysplasia of the hip. There were 38 cases (54 hips) in conventional THA group (conventional group), with 19 males and 19 females, (age 52.3±14.7 years old, BMI 25.7±2.9 kg/m 2), and there were 19 cases (30 hips) with developmental dysplasia of the hip, and 19 cases (24 hips) with osteonecrosis of the femoral head. The operative time, postoperative LLD, Harris score, forgotten joint score-12 (FJS-12) and the difference between preoperative and postoperative LLD between the two groups were compared, and the correlation between surgical methods and the change of hip length was also evaluated. Results:The operation time of the robot group was 73.3±14.1 min and which was 59.3±12.6 min in conventional THA group ( t=2.732, P=0.003). In the robot group, the postoperative LLD was 2.3±3.4 mm, which was less than that of the conventional group 6.7±5.4 mm ( t=3.521, P < 0.001). When the absolute value of LLD was larger than 5 mm as an abnormal value, it was 2.6% (1/38) in the robot group and 47.3% (18/38) in the conventional group. The difference of hip length (HL) in planning and post-operation in the robot group was 2.8±2.2 mm, which was smaller than that in the conventional THA group 7.9±5.3 mm ( t=2.357, P < 0.001). In addition, there was a correlation between the change of hip length results and the postoperative measurement of hip length in the robot group ( r=0.983, P < 0.001). At the last follow-up, Harris score and FJS-12 were recorded in the robot group and coventional group. The scores were 83.1±5.3 and 32.5±4.9 respectively in the robot group, 82.9±7.2 and 31.9±6.7 in the conventional group, respectively. There was no significant difference between the two groups ( t=0.221, 0.356; P=0.819, 0.731). Postoperative bleeding occurred in 1 case in the robot group with postoperative suture healed well. The fracture of the posterior wall of the acetabulum was found in the conventional group and the patient avoids weight bearing 4 weeks after operation. The postoperative recovery was good and no other related complications were found. Conclusion:Robot-assisted THA can accurately restore the length of both legs and reduce LLD compared with conventional THA. The real-time monitoring of LLD during robot operation can give the operator an accurate reference.
