ABSTRACT

Objective To investigate the population differences of the newly named "metabolic associated fatty liver disease" (MAFLD) and the former name "nonalcoholic fatty liver disease" (NAFLD). Methods From November 2020 to January 2021, a cross-sectional survey was conducted among 624 elderly individuals aged above 65 years in a community in Beijing, China, and related data were collected, including demographic data, past history, laboratory markers, liver ultrasound, and liver elasticity. According to the presence or absence of fatty liver based on ultrasonic diagnosis, the individuals were divided into fatty liver group with 389 individuals and non-fatty liver group with 235 individuals. The independent samples t -test was used for comparison of normally distributed continuous data between the two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between the two groups; the chi-square test was used for comparison of categorical data between the two groups. Results Among the 389 patients with fatty liver, 387(99.5%) were diagnosed with MAFLD and 368(94.6%) were diagnosed with NAFLD, and there were 19 patients with a history of heavy alcohol consumption and 2 with positive surface antigen. A total of 366 patients met the diagnostic criteria for both MAFLD and NAFLD, accounting for 94.6% of the MAFLD patients and 99.5% of the NAFLD patients. Compared with the non-fatty liver group, the MAFLD group had significant increases in body mass index (BMI) ( t =-11.228, P < 0.05), waist circumference ( Z =-8.532, P < 0.05), hip circumference ( Z =-6.449, P < 0.05), waist-hip ratio ( Z =-5.708, P < 0.05), alanine aminotransferase ( Z =-5.027, P < 0.05), aspartate aminotransferase ( Z =-2.880, P < 0.05), platelet count ( t =-3.623, P < 0.05), triglyceride ( Z =-8.489, P < 0.05), fasting blood glucose ( Z =-3.516, P < 0.05), HbA1c ( Z =-2.884, P < 0.05), Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) ( Z =-0.394, P < 0.05), high-sensitivity C-reactive protein ( Z =-4.912, P < 0.05), controlled attenuation parameter (CAP) ( t =13.744, P < 0.05), and liver stiffness measurement (LSM) ( Z =-7.69, P < 0.05), as well as a significant reduction in high-density lipoprotein cholesterol (HDL-C) ( t =6.348, P < 0.001). Meanwhile, MAFLD patients had more metabolic associated diseases, such as overweight, obesity, central obesity, dyslipidemia, and hypertension ( χ 2 =9.978, 65.472, 36.571, 9.797, and 5.128, all P < 0.05). In the MAFLD group, 30.7% of the patients had non-obese fatty liver disease (BMI < 25 kg/m 2 ), and 11.1% had lean fatty liver disease (BMI < 23 kg/m 2 ); compared with the obese MAFLD patients, the non-obese MAFLD patients had significantly lower age ( Z =-3.042, P < 0.05), BMI ( Z =-15.705, P < 0.05), waist circumference ( Z =-9.589, P < 0.05), hip circumference ( Z =-10.275, P < 0.05), HOMA-IR ( Z =-2.081, P < 0.05), CAP ( t =-3.468, P < 0.05), LSM ( Z =-3.630, P < 0.05), and NAFLD fibrosis score ( t =-4.433, P < 0.05). According to LSM value, advanced liver fibrosis accounted for 3.6% of the MAFLD population, and 10% of the MAFLD population could not be excluded for advanced liver fibrosis. Conclusion The diagnosis of MAFLD can basically cover the NAFLD population in the elderly people, and it is supposed that MAFLD can almost directly replace the concept of NAFLD in similar populations. However, further studies are needed to investigate its application in other populations.

ABSTRACT

OBJECTIVE@#To explore the effectiveness of Danhong Injection () on improving microcirculatory injury after percutaneous coronary intervention (PCI) in patients with coronary heart disease (CHD).@*METHODS@#A randomized controlled trial was conducted and 90 patients were enrolled. A random sequence was generated using statistical analysis software. Patients with microcirculatory injuries after PCI were randomly divided into 3 groups for treatment (30 subjects in each group): Danhong Injection group: after PCI, Danghong Injections were given with intravenous administration with 40 mL twice a day for a week; statins intensive group: after PCI, atorvastatin calcium tablets were given oral medication with 80 mg once, and then atorvastatin 40 mg daily for 1 week; the control group: after PCI, atorvastatin calcium tablets were given oral medication with 10-20 mg daily for 1 week. The index of microcirculation resistance (IMR) was used to assess microcirculatory injury during PCI. The IMR of the target vessel was reexamined after 1 week of drug treatment.@*RESULTS@#After one week's drug treatment, IMR was significantly decreased in both statins intensive group and Danhong Injection group compared with the control group (P<0.01), but no difference was found between statins intensive group and Danhong injection group (14.03 ± 2.54 vs. 16.03 ± 5.72 U, P=0.080).@*CONCLUSIONS@#The efficacy of Danhong Injection is non-inferior to statin. Early use of Danhong Injection after PCI can effectively improve coronary microcirculation injury after PCI.

ABSTRACT

OBJECTIVE@#To observe the effect of long-term moxa smoke exposure of different concentrations on olfactory function in rats, and provide experimental basis of safety study of moxa smoke produced by moxibustion.@*METHODS@#Forty SD rats were randomly divided into a normal control group, a low-concentration moxa smoke group, a moderate-concentration moxa smoke group and a high-concentration moxa smoke group, 10 rats in each one. The rats in the moxa smoke groups were put into three plexiglass moxibustion boxes with different moxa smoke concentrations, 4 hours per times, twice a day for 90 days. The general state of rats was evaluated before and during the experiment. After the intervention, the olfactory function was evaluated by two-bottle experiment (TBE); the morphology of nasal mucosa was observed by HE staining; the apoptosis of olfactory epithelial cells in nasal mucosa was detected by TUNEL method; the serum levels of interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were detected by ELISA method.@*RESULTS@#In the late stage of moxa smoke exposure (45-90 days into intervention), the behavioral activity of rats in the moderate-concentration moxa smoke group and the high-concentration moxa smoke group was weaker than that in the normal control group, and their response to stimulation was strong, and their mental state was worse. After intervention, the drinking rate of vinegar-water mixture in the moderate-concentration moxa smoke group and the high-concentration moxa smoke group was higher than that in the normal control group and the low-concentration moxa smoke group (@*CONCLUSION@#The long-term exposure to low, moderate and high concentrations of moxa smoke could cause pathological changes in nasal mucosa and increase the serum levels of IL-1, IL-6 and TNF-α; the moderate and high concentrations of moxa smoke exposure could cause a series of damage to olfactory function and reduce olfactory sensitivity in rats.

ABSTRACT

The prompt detection and proper evaluation of necrotic retinal region are especially important for the diagnosis and treatment of acute retinal necrosis (ARN). The potential application of artificial intelligence (AI) algorithms in these areas of clinical research has not been reported previously. The present study aims to create a computational algorithm for the automated detection and evaluation of retinal necrosis from retinal fundus photographs. A total of 149 wide-angle fundus photographs from 40 eyes of 32 ARN patients were collected, and the U-Net method was used to construct the AI algorithm. Thereby, a novel algorithm based on deep machine learning in detection and evaluation of retinal necrosis was constructed for the first time. This algorithm had an area under the receiver operating curve of 0.92, with 86% sensitivity and 88% specificity in the detection of retinal necrosis. For the purpose of retinal necrosis evaluation, necrotic areas calculated by the AI algorithm were significantly positively correlated with viral load in aqueous humor samples (

ABSTRACT

Objective:To evaluate the association between thrombus composition and mechanical recanalization,operation procedure and clinical outcome.Methods:One hundred and ninety-two consecutive stroke patients with large-vessel occlusion treated by mechanical thrombectomy using a stent retriever and (or) aspiration catheter in the Affiliated Huaian No.1 People′s Hospital of Nanjing Medical University between January 2018 and January 2020 were collected. The retrieved thrombi were quantitatively analyzed for red blood cells, white blood cells, platelets, and fibrin. The patients were divided into two groups, a erythrocyte-rich group and a fibrin-rich group based on the predominant composition in the clot. The clinical prognosis, CT value of thrombus, procedure time,number of recanalization maneuvers, and degree of vascular recanalization were compared between the two groups.Results:The retrieved clot from 138 patients with acute ischemic stroke from internal carotid artery occlusion ( n=56), middle cerebral artery occlusion ( n=62), intracranial segment of vertebral artery or basilar artery occlusion( n=20) were histologically analyzed. Erythrocyte-rich clots were present in 59 cases, while fibrin-rich clots were present in 79 cases. Cardioembolic thrombi had higher proportions of fibrin/platelets [77.2%(61/79)], less erythrocytes than noncardioembolic thrombi [45.8%(27/59), χ2=8.115, P=0.004]. Patients with erythrocyte-rich thrombi had a smaller number of recanalization maneuvers [2 (1, 2) vs 3 (2, 4), Z=-7.613, P<0.001], shorter procedure time [45 (30, 60) min vs 80 (60, 90) min, Z=-6.944, P<0.001], higher thrombus CT value [42 (32, 53) vs 36 (31, 41), Z=-2.003, P=0.045], good clinical prognosis (the ratio of modified Rankin Scale score ≤2, 62.7% (37/59) vs 39.2% (31/79), χ2=7.444, P=0.006). There was no significant difference in the location of vascular occlusion between the two groups. Conclusion:For patients whose thrombotic components are mainly red blood cells, the cause of stroke may be non cardiogenic cerebral embolism, the CT value of embolus is relatively high, the embolus is easy to remove, and the clinical prognosis is relatively good.

ABSTRACT

Objective:To quantitatively evaluate the left ventricular myocardial strains and global myocardial work indices in severe aortic stenosis(AS) patients with preserved left ventricular ejection fraction (LVEF) undergoing transcatheter aortic valve implantation (TAVI) by using two-dimensional speckle tracking imaging (2D-STI) technology and pressure-strain loop (PSL).Methods:Twenty patients undergoing TAVI from January to November 2020 in Cardiovascular Hospital of Xiamen University were selected as the TAVI group, and 20 healthy volunteers (with the matched gender, age) were selected as the control group at the same period. Left ventricular global longitudinal strain (GLS), endocardial, middle, epicardial myocardial longitudinal strain (LSendo, LSmid, LSepi) were measured by 2D-STI. The correlation between aortic pressure and the left ventricular systolic pressure invasively measured by cardiac catheterization, and blood pressure and the left ventricular systolic pressure non-invasively measured by peripheral brachial artery systolic blood pressure combined with Doppler-derived mean aortic gradient was separately compared. The non-invasive PSL was used to evaluate the global work index (GWI), global constructive work (GCW), global wasted work (GWW) and global work efficiency (GWE). The differences of the myocardial strains and myocardial work indices between the two groups, including controls, patients with preoperation, 1 week and 3 months after TAVI, were compared.Results:Compared with the control group, GLS, LSendo, LSmid and LSepi of the left ventricle in the TAVI preoperation group were decreased (all P<0.05), LSendo increased at 1 week after TAVI, and GLS, LSendo, LSmid, and LSepi increased at 3 months after TAVI (all P<0.05). In the TAVI preoperative, invasive aortic pressure was positively correlated with peripheral brachial artery systolic blood pressure, invasive left ventricular systolic pressure was positively correlated with non-invasive left ventricular systolic pressure ( r=0.658, 0.565; all P<0.01). Compared with the control group, the preoperative the GWE decreased and the GWW increased in the TAVI group (all P<0.05). Compared with the preoperation, the GWI and GCW decreased at 1 week after TAVI (all P<0.05). Compared with 1 week after TAVI, GWI, GCW, GWE increased and GWW decreased at 3 months after TAVI (all P<0.05). Conclusions:The application of 2D-STI and PSL can quantitatively evaluate the left ventricular myocardial systolic function before and after TAVI in AS patients, which can provide a more objective reference index for clinical evaluation of the efficacy of TAVI.

ABSTRACT

Objective:To study on the effects of gastrointestinal function and portal vein hemodynamics applicated with abdominal hot compressing with evodiae fructus and crude salt after hepatectomy.Methods:A total of 60 patients who underwent hepatectomy were randomly divided into 2 groups by random number table method, with 30 in each group. The control group was treated with conventional basic western medicine, while the treatment group was treated with medicinal evodiae fructus and crude salt hot compress on abdomen on the basis of the control group. The portal vein diameter (PVD), portal venous flow velocity (PVV), recovery time of main clinical indexes, clinical symptom scores and liver function indexes were dynamically monitored at different observation time points.Results:The scores of abdominal distension, nausea and vomiting in the treatment group were significantly lower than those in the control group 3 days after treatment ( t values were -3.489 and -2.740, respectively, all Ps<0.05). The recovery time of bowel sounds, first exhaust time and first defecation time in the treatment group were significantly earlier than those in the control group ( t values were -3.622, -4.297 and -4.151, respectively, all Ps<0.01). With the extension of treatment time, ALT in 2 groups showed a gradual downward trend ( P<0.05 or P<0.01), DBIL in control group was significantly higher at 3 days after treatment than before ( t=-2.157, P=0.039), and TBIL was significantly lower at 7 days after treatment than before ( t=2.175, P=0.038). The PVD ( t values were 3.528, 2.160) and PVV ( t values were 11.096, 4.264) of the treatment group were significantly higher than those of the control group 3 and 5 days after treatment ( P<0.01 or P<0.05). Conclusion:Early application of abdominal hot compressing with evodiae fructus and crude salt hot compress on abdomen after hepatectomy can improve the portal vein blood circulation and promote the rehabilitation of gastrointestinal function in patients with hepatectomy.

ABSTRACT

In recent years, the incidence rate of andrological diseases has shown a significant growth trend. Considering the unavailability of a perfect theoretical system for andrology in traditional Chinese medicine (TCM) and the complex pathogenesis despite of the limited types of andrological diseases, it is necessary to improve the clinical efficacy of andrological diseases so as to satisfy the needs of patients. Therefore, the China Association of Chinese Medicine (CACM) organized the andrologists of TCM and western medicine and the outstanding young clinicians to discuss the andrological diseases responding specifically to TCM or integrated TCM and western medicine, such as chronic prostatitis, male infertility, benign prostatic hyperplasia, erectile dysfunction, and premature ejaculation, determine their diagnostic criteria in western medicine, and standardize the specifications for TCM diagnosis and treatment based on syndrome differentiation, thus formulating recognized and integrated diagnosis and treatment protocols. Apart from proposing suggestions on the treatment of such andrological diseases with TCM and western medicine, the experts have also figured out the andrological diseases responding specifically to TCM, the optimal intervention time of TCM and western medicine, and the suitable measures including surgery. The resulting consensus helps to better guide the formulation of accurate, personalized, and optimized treatment plans in clinical practice and improve the diagnosis and treatment effects of andrological diseases by giving full play to the advantages of TCM, which will in turn contribute to further innovation and development of TCM.

ABSTRACT

Background/Aims@#Nonalcoholic steatohepatitis (NASH) is a progressive form of nonalcoholic fatty liver disease (NAFLD) characterized by hepatic steatosis, inflammation, hepatocellular injury, and fibrosis. We aimed to investigate the usefulness of a key biomarker, lipocalin-2 (LCN2), for the detection of NASH progression. @*Methods@#A mouse NASH model was established using a high-fat diet and a high-sugar drinking water. Gene expression profile of the NASH model was analyzed using RNA sequencing. Moreover, 360 NAFLD patients (steatosis, 83; NASH, 277), 40 healthy individuals, and 87 patients with alcoholic fatty liver disease were recruited. @*Results@#Inflammatory infiltration, focal necrosis in the leaflets, steatosis, and fibrosis were documented in the mouse liver. In total, 504 genes were differentially expressed in the livers of NASH mice, and showed significant functional enrichment in the inflammation-related category. Upregulated liver LCN2 was found to be significantly interactive with various interleukins and toll-like receptors. Serum LCN2 levels were significantly increased in NAFLD patients. Serum LCN2 levels were correlated with steatosis, intralobular inflammation, semiquantitative fibrosis score, and nonalcoholic fatty liver disease activity score. The area under the curve of serum LCN2 was 0.987 with a specificity of 100% and a sensitivity of 93.5% for NASH diagnosis, and 0.977 with almost the same specificity and sensitivity for steatosis. @*Conclusions@#LCN2 might be involved in the transition from NAFL to NASH by mediating inflammation. Serum LCN2 levels might be a novel biomarker for the diagnosis of NASH.

ABSTRACT

OBJECTIVE@#To evaluate the effect of Danhong Injection (, DH) on the index of microcirculatory resistance (IMR) and myocardial injury in patients with unstable angina undergoing elective percutaneous coronary intervention (PCI).@*METHODS@#Seventy-eight patients with unstable angina were randomly divided into DH group (39 cases) and the control group (39 cases) during elective PCI. Randomization was performed using a random-number table. The DH group received DH at a dosage of 40 mL (mixed with 250 mL saline, covered by a light-proof bag, intravenous drip) during PCI and daily for 7 consecutive days, while the control group only received the same dosage of saline. Both groups received standardized treatment. The IMR and fractional flow reserve (FFR) were measured at maximal hyperemia before and after PCI. Myocardial markers, including myoglobin, creatine kinase (CK), creatine kinase MB (CK-MB), and coronary troponin T (cTnT) values were measured at baseline and 24 h after PCI.@*RESULTS@#Among the 78 patients enrolled, the baseline and procedural characteristics were similar between the two groups. There was no significant difference in pre-PCI myocardial markers and coronary physiological indexes between the two groups. However, post-PCI CK and CK-MB levels in the DH group were significantly lower than those in the control group (111.97 ± 80.97 vs. 165.47 ± 102.99, P=0.013; 13.08 ± 6.90 vs. 19.75 ± 15.49, P=0.016). Post-PCI myoglobin and cTNT-positive tend to be lower in the DH group than in the control group but did not reach statistical significance (88.07 ± 52.36 vs. 108.13 ± 90.94, P=0.52; 2.56% vs.7.69%, P=0.065). Compared with the control group, the post-IMR levels of the DH group tended to decrease, but there was no statistical difference (20.73 ± 13.15 vs. 26.37 ± 12.31, P=0.05). There were no statistical differences in post-FFR in both groups. The peri-procedural myocardial injury of the DH group was significantly lower than that of the control group (2.56% vs. 15.38%, P=0.025). During the 30-d follow-up period, no major adverse cardiovascular events occurred in either group.@*CONCLUSION@#This study demonstrated benefit of DH in reducing myocardial injury and potential preserving microvascular function in patients with unstable angina undergoing elective PCI.

ABSTRACT

Objective:To explore the clinical characteristics and influencing factors of refractory lupus thrombocytopenia (RLTP) secondary to systemic lupus erythematosus (SLE).Methods:A retrospective analysis of 113 patients with thrombocytopenia secondary to SLE in the outpatient and inpatient Department of Rheumatology of the First Affiliated Hospital of Soochow University from January 2015 to June 2018 was carried out. The medical record and laboratory tests of patients were collected, and they were divided them into the refractory group (RLTP, n=25) and non-refractory group (NRLTP, n=88). The clinical manifestations, blood count, biochemical and immunological test of the two groups were analyzed and compared. All data were analyzed by t-test, Mann-Whitney test, χ2 test, Logistic regression analysis and Kaplan-Meier survival analysis. Results:Compared with NRLTP patients, RLTP patients had longer disease course [72(30, 120) months vs 38.5 (8.5, 93) months, H=-2.401, P=0.016), nervous system damage (28% vs 7%, χ2=8.58, P=0.016), higher bleeding risk [(4.6±1.7) vs (3.8±1.3), t=2.548, P=0.012] and higher mortality rate (8% vs 0, χ2=7.167, P<0.01). Meanwhile, the positive rate of anti-GPⅠb/Ⅸ in RLTP group was significantly higher than that in NRLTP group (27% vs 4%, χ2= 8.647, P<0.01). Further unconditional multivariate logistic regression analysis showed that anti-GPⅠb/Ⅸ positive was one of the main influencing factors of RLTP. Kaplan-Meier survival curve analysis revealed that the cumulative survival rate of RLTP group was significantly lower than that of NLTP group ( χ2=7.909, P<0.01). Conclusion:RLTP has a long course of disease, prone to nervous system impairment and positive anti-GPⅠb/Ⅸ antibody, and has a high risk of bleeding. It is necessary to identify these patients early, adjust treatment strategies and improve the prognosis of patients.

ABSTRACT

Objective:To explore the curative efficacy of pelvic reconstruction plate and T-plate elastic fixation in the treatment of acetabular fractures with comminuted posterior wall.Methods:A retrospective analysis was conducted of the 21 patients who had been treated at Department of Orthopaedics, Affiliated Hospital to the Second Mongolia Medical University for acetabular fractures with comminuted posterior wall from January 2017 to June 2019. They were 15 males and 6 females, aged from 29 to 55 years (average, 41.5 years). According to the Letournel-Judet classification, there were 15 cases of simple posterior wall fracture with dislocation of the femoral head, 4 cases of posterior wall and posterior column fracture, and 2 cases of double-column and posterior wall fracture. The time from injury to surgery averaged 3 days (from 2 to 5 days). The posterior acetabulum was treated by pelvic reconstruction plate combined with T-plate elastic fixation through the posterior acetabular Kocher-Langenbeck approach. Postoperative fracture reduction, fracture union time, function of the affected hip and complications at the last follow-up were evaluated.Results:This group of 21 patients were followed up for 6 to 24 months (average, 15 months). By the Matta imaging scoring, the postoperative reduction of the posterior wall fracture was evaluated as excellent in 18 cases and as good in 3, giving an excellent to good rate of 100%. The fracture union time averaged 10 weeks (from 8 to 12 weeks) for this group. By the improved Merle d'Aubigné & Postel evaluation at the last follow-up, the affected hips scored from 12 to 18 points (average, 16 points), yielding 18 excellent, 2 good and one poor cases, giving an excellent to good rate of 95.2%. There was no major hemorrhage, nerve injury or deep vein thrombosis intraoperatively. During the follow-up, mild ectopic ossification occurred in one case, and subluxation of the femoral head and traumatic arthritis were observed in another, but no patient had other complications like avascular necrosis of the femoral head.Conclusion:In the treatment of acetabular fracture with comminuted posterior wall, pelvic reconstruction plate and T-plate elastic fixation through the posterior acetabular Kocher-Langenbeck approach can lead to fine short-term outcomes.

ABSTRACT

Objective:To explore the effect of mifepristone combined with methotrexate intracapsular injection on pregnancy at scar site of endogenous cesarean section.Methods:From June 2014 to June 2019, 106 cases of pregnancy at scar site of endogenous cesarean section admitted to Jinhua Maternal and Child Health Hospital were selected in the research.According to the random number table method, the patients were divided into control group and observation group, with 53 cases in each group.The control group received hysteroscopy curettage only, routine anti-infection, curettage under the guidance of B-ultrasound.The observation group was given mifepristone and methotrexate intracapsular injection on the basis of the control group.The clinical effect, recovery time of serum β-HCG, intraoperative blood loss, postoperative complications and hospitalization time were compared between the two groups.Results:The total effective rate of the observation group[92.45%(49/53)] was higher than that of the control group[75.47%(40/53)](χ 2=5.675, P<0.05). The recovery time of β human chorionic gonadotropin (β-HCG) in the observation group[(17.58±2.54)d] was faster than that in the control group[(21.83±4.13)d], and the intraoperative blood loss[(25.42±5.46)mL] was less than that in the control group[(87.93±18.47)mL], the differences were statistically significant ( t=6.381, 23.628, all P<0.05). The incidence of postoperative complications of the observation group (1.89%) was lower than that of the control group (9.43%), but there was no statistically significant difference between the two groups (χ 2=1.590, P>0.05). The hospitalization time of the observation group[(7.83±1.52)d]was shorter than that of the control group[(9.68±2.19)d]( t=5.052, P<0.05). Conclusion:Mifepristone combined with methotrexate intracapsular injection has good clinical effect on endogenous cesarean scar pregnancy.It can accelerate the recovery time of blood β-HCG, which is worthy of clinical reference.
