Objective To investigate the effect of early glucose metabolism abnormality on skeletal muscle content of young men.Methods 88 males who underwent physical examinations in our hospital from September 2020 to September 2021 were divided into normal blood glucose group(NGT,n=47)and IGR group(n=41),according to their FPG and 2 hPG levels.FPG,FIns and visceral fat area(VFA)were measured.HOMA-IR,HOMA-β,skeletal muscle index(SMI)and body fat ratio(BFR)were calculated.Results Compared with NGT group,the males in IGR group showed elevated BMI,WC,FPG,2 hPG,HOMA-IR and VFA(P＜0.05),but decreased HDL-C and SMI(P＜0.05).Pearson correlation analysis showed that SMI was negatively correlated with BMI,WC,FPG,2 hPG,HOMA-IR,VFA and BFR in young men(P＜0.05 or P＜0.01).Logistic regression analysis showed that BMI was the influencing factor of FPG,while SMI was the influencing factor of 2 hPG.Conclusions In young men with abnormal glucose metabolism,the postprandial blood glucose significantly increase with the decrease of skeletal muscle content,and fasting blood glucose is mainly affected by BMI.

Objective:To evaluate the morphological and functional changes of the heart during second trimester fetuses with ventricular septal defect (VSD) using fetal heart quantification (fetal HQ) technology.Methods:A prospective study was conducted from July 2022 to January 2024 at Chengdu Women′s and Children′s Central Hospital, collecting 91 singleton fetuses diagnosed with isolated VSD (VSD group) and 91 normal fetuses matched for gestational age (control group). Fetal HQ technology was used to measure the length and width of the four-chamber view of the fetal heart, obtaining the global sphericity index (GSI). Speckle tracking technology was used to track the endocardial motion trajectories of the left and right ventricles during diastole and systole, obtaining parameters such as left and right ventricular global longitudinal strain (LV-GLS and RV-GLS), end-diastolic diameter (EDD), 24-segment sphericity index (SI), 24-segment fraction of shortening (FS), left ventricular ejection fraction (LV-EF), fraction of area change (FAC), left ventricular stroke volume (LV-SV), and left ventricular cardiac output (LV-CO).The differences between groups were compared, and the correlations between the values of VSD and GSI, GLS, and FAC were evaluated.Results:The EDD of the left ventricular segments 20-23 in the VSD group was lower, while the SI value of the right ventricular segments 1-4 in the VSD group was higher than that in the control group (all P<0.05). There was no statistically significant difference in GSI between the two groups ( P>0.05). LV-GLS in the VSD group was lower than that in the control group ( P<0.05). There was no statistically significant difference in RV-GLS ( P>0.05). Values of LV-FAC, LV-EF, LV-SV, and LV-CO in the VSD group were significantly lower than those in the control group (all P<0.05). The FS value of left ventricular segments 1-10 in the VSD group presented lower, but the FS value of right ventricular segments 7-21 higher compared to controls(all P<0.05). LV-GLS and LV-FAC absolute values were negatively correlated with the size of VSD ( r=-0.309, P=0.004; r=-0.264, P=0.015), while GSI, RV-GLS, and RV-FAC showed no significant correlation with the size of VSD (all P>0.05). Conclusions:The overall sphericity index of second trimester VSD fetuses is normal, but there are changes in the shape of the left ventricular apical segments and the right ventricular basal segments, with the left heart chamber tending to be flatter and the right heart chamber more fusiform. The left ventricular systolic function of VSD fetuses is significantly reduced, the local systolic function of right ventricular increases while the global systolic function shows no significant change. The absolute values of LV-GLS and LV-FAC in VSD fetuses are negatively correlated with the size of VSD.

Objective To investigate the effect of orthokeratology combined with repeated low-level red-light(RL-RL)therapy on progressive myopia in adolescents.Methods A total of 106 adolescents(212 eyes)with progressive my-opia admitted to our hospital from March 2020 to September 2022 were selected and randomly classified into an observation group(n=57,114 eyes)and a control group(n=49,98 eyes).Patients in the observation group received orthokeratology and RLRL therapy,and patients in the control group received orthokeratology only.All patients were followed up for 1 year.The uncorrected visual acuity(UCVA),axial length(AL),diopter,tear film lipid layer thickness(LLT),break-up time(BUT),subfoveal choroidal thickness(SFChT),and the incidence of complications at different time points were compared between the two groups.Results Analysis of variance on the UCVA,diopter,LLT,BUT and SFChT at differ-ent time points before and after treatment revealed a significant time effect and time × group interaction effect(all P＜0.05),but no statistical group effect(all P＞0.05).For the AL,there was a significant time effect(P＜0.05),but no time x group interaction effect or group effect(all P＞0.05).Twelve months after treatment,the UCVA,LLT decrease and SFChT thickening were greater in the observation group compared to the control group,while the diopter progression and AL increase were milder in the observation group than in the control group(all P＜0.05).Changes in BUT yielded no sta-tistical difference between the two groups(P＞0.05).The complication rate demonstrated no statistical difference between the two groups(P＞0.05).Conclusion The application of RLRL therapy combined with orthokeratology for progressive myopia in adolescents can effectively improve the UCVA and control the growth of AL and diopter,with high safety.

Objective:To explore the effects of body mass index (BMI) on the incidence of nocturnal hypertension in patients with hypertension.Methods:Totally 341 hospitalized hypertensive patients treated at the Affiliated Hospital of Jining Medical University from February to May 2023 were selected by convenience sampling. Patients' general information, clinical data, and 24-hour ambulatory blood pressure results were collected. A binomial Logistic regression analysis was conducted to investigate the factors affecting the occurrence of nocturnal hypertension in these patients. The relationship between BMI and the incidence of nocturnal hypertension was examined using threshold effect tests and smooth curve fitting.Results:The binomial Logistic regression analysis indicated that blood phosphate level was a factor influencing the occurrence of nocturnal hypertension in hypertensive patients ( P<0.05). Smooth curve fitting and threshold effect test results showed that the relationship between BMI and the incidence of nocturnal hypertension was curve-correlated, with a turning point at 24.61 kg/m 2. To the left of the turning point, there was no correlation ( P=0.130) ; to the right, there was a correlation ( P=0.016) . Conclusions:When the BMI of hypertensive patients exceeds 24.61 kg/m 2, the likelihood of nocturnal hypertension increases with rising BMI, providing a precise intervention target for weight management-based patient care in hypertension.

Objective In order to address the issues of inconvenience,high medical costs,and lack of universality associated with traditional knee rehabilitation equipment,a portable intelligent wheelchair for knee rehabilitation was designed in this study.Methods Based on the analysis of the knee joint's structure and rehabilitation mechanisms,an electric pushrod-driven rehabilitation institution was developed.A multi-functional module was designed with a modular approach,and the control of the wheelchair body and each functional module was implemented using an STM32 single-chip microcomputer.A three-dimensional model was established using SolidWorks software.In conjunction with Adams and Ansys simulation software,kinematic and static analyses were conducted on the knee joint rehabilitation institution and its core components.A prototype was constructed to verify the equipment's actual performance.Results According to the prototype testing,the actual range of motion for the knee joint swing rod is 15.1°～88.9°,the angular speed of the swing rod ranges from-7.9 to 8.1°/s,the angular acceleration of the swing rod varies from-4.2 to 1.6°/s2,the thrust range of the electric pushrod is-82.6 to 153.1 N,and the maximum displacement of the load pedal is approximately 1.7 mm,with the leg support exhibiting a maximum deformation of about 1.5 mm.Conclusion The intelligent knee joint rehabilitation wheelchair meets the designed functions and its actual performance aligns with the design criteria,thus validating the rationality and feasibility of the structural design.

【Objective】 To discuss the effect of adding tranexamic acid(TXA) during surgery on blood loss and security during short segment lumbar spinal stenosis surgery. 【Methods】 One hundred and eight patients with lumbar spinal stenosis who were to undergo lumbar posterior fusion surgery were randomly divided into control group, TXA group and adding TXA group, with 36 patients in each group. In the control group, TXA was not used during surgery.The TXA group received intravenous infusion of 100 mL normal saline mixture containing 1 g of TXA 15 minutes before surgery after anesthesia. In adding TXA group, after the same operation in TXA group, 10 mg/kg(body weight) of TXA was infused 3 hours later. Total perioperative blood loss, dominant blood loss, hidden blood loss, intraoperative blood loss, postoperative drainage volume, and transfusion rate were recorded in the two groups. Hemoglobin (Hb), hematocrit(HCT), prothrombin time international standardized ratio (PT-INR), prothrombin time(PT), activated partial thromboplastin time(APTT), blood platelet count (BPC), D-dimer (D-D), fibringen(FIB), C-reactive protein (CRP), alanine aminotransferase (ALT), blood urea nitrogen (BUN) were measured 3 days before and after the surgery in the three groups. Postoperative adverse events were followed up. 【Results】 The total blood loss(mL) [(968.7±209.6) vs (1 369.8±276.3), (968.7±209.6) vs (1 273.9±250.2)], dominant blood loss(mL) [(590.5±164.3) vs (876.4±235.9), (590.5±164.3) vs (789.3±221.7)], intraoperative blood loss(mL) [(318.7±120.7) vs (457.8±146.6), (318.7±120.7) vs (423.9±162.3)] and postoperative drainage volume(mL) [1 day after surgery: (164.6±25.0) vs (262.3±51.7), (164.6±25.0) vs (219.8±37.1); 3 days after surgery: (107.2±18.6) vs (156.3±37.6), (107.2±18.6) vs (145.3±22.3)] of the adding TXA group were lower than those of the control group and TXA group (P<0.05), and the transfusion rate was lower than that of the control group (P<0.05).The postoperative drainage volume and transfusion rate of TXA group were lower than that of the control group (P<0.05).There was no statistical difference in the amount of hidden blood loss between the three groups (P>0.05). Compared with the preoperative results, Hb, Hct and BPC in the three groups decreased (P<0.05), and D-D, FIB and CRP increased (P<0.05), but the change degree of Hb, Hct, BPC, D-D and CRP in the TXA group and the adding TXA group was less than that in the control group (P<0.05), and the change degree of Hb, Hct, BPC, D-D and CRP in the adding TXA group was less than that in the TXA group (P<0.05).There was no statistically significant difference in PT-INR, PT, APTT, ALT and BUN between and within the three groups before and after surgery (P>0.05), and all of them were within the normal range. No serious adverse events such as deep vein thrombosis, pulmonary embolism, epilepsy, liver and kidney damage were found in all patients after postoperative follow-up. 【Conclusion】 Intraoperative addition of TXA can effectively reduce the amount of blood lost during short segment lumbar spinal stenosis surgery without increasing the risk of complications such as coagulation disorders, thrombosis, liver and kidney function damage.

Bioactive compounds derived from herbal medicinal plants modulate various therapeutic targets and signaling pathways associated with cardiovascular diseases (CVDs), the world's primary cause of death. Ginkgo biloba, a well-known traditional Chinese medicine with notable cardiovascular actions, has been used as a cardio- and cerebrovascular therapeutic drug and nutraceutical in Asian countries for centuries. Preclinical studies have shown that ginkgolide B, a bioactive component in Ginkgo biloba, can ameliorate atherosclerosis in cultured vascular cells and disease models. Of clinical relevance, several clinical trials are ongoing or being completed to examine the efficacy and safety of ginkgolide B-related drug preparations in the prevention of cerebrovascular diseases, such as ischemia stroke. Here, we present a comprehensive review of the pharmacological activities, pharmacokinetic characteristics, and mechanisms of action of ginkgolide B in atherosclerosis prevention and therapy. We highlight new molecular targets of ginkgolide B, including nicotinamide adenine dinucleotide phosphate oxidases (NADPH oxidase), lectin-like oxidized LDL receptor-1 (LOX-1), sirtuin 1 (SIRT1), platelet-activating factor (PAF), proprotein convertase subtilisin/kexin type 9 (PCSK9) and others. Finally, we provide an overview and discussion of the therapeutic potential of ginkgolide B and highlight the future perspective of developing ginkgolide B as an effective therapeutic agent for treating atherosclerosis.

Objective:To explore the best treatment for local ablation of colon cancer liver metastases (CRLM) by meta-analysis.Methods:The electronic databases of PubMed, Web of Science, Embase, CNKI and the Cochrane Library were searched from the establishment to August 22, 2022, and studies that report outcomes with comparison between microwave ablation (WMA) and radiofrequency ablation (RFA) in CRLM treatment were selected by inclusion and exclusion criteria. Furthermore, the perioperative and survival data were statistically summarized and analyzed by Review Manager 5.3 software.Results:A total of 5 retrospective studies were included with a total sample size of 648 cases, including 316 cases (48.8%) in the WMA group and 332 cases (51.2%) in the RFA group. The results of meta-analysis showed that locoregional recurrence rate in WMA group was significantly lower than that in RFA group. The 1-year and 2-year disease-free survival (DFS) of the WMA group was significantly better than that of the RFA group with HR of 1.77 ( P=0.04, 95% CI: 1.04-3.02) and 1.60 ( P=0.02, 95% CI: 1.09-2.35), respectively. Conclusion:The local control rate and 1-year and 2-year DFS of WMA were superior to RFA.

Objective The homological analysis of a foodborne disease outbreak event that occurred on July 15, 2022, in Sanya was carried out to provide scientific basis for clinical treatment, incident tracing and prevention and control, and to explore the feasibility of pulsed field gel electrophoresis (PFGE) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) in the homology analysis of Salmonella bacteria. Methods The traceability analysis of food poisoning incidents was accurately analyzed through the combination of traditional bacterial detection methods, PFGE, MALDI-TOF MS and the clinical symptom, epidemiological characteristics. Results In this outbreak, 14 cases of poisoning symptoms such as fever, nausea, and vomiting appeared, all of which had a history of dining in the same restaurant, with similar onset and clinical manifestations. Among them, one was the chef who made the fried rice in the restaurant. The pathogen culture and identification showed that it was caused by Salmonella typhimurium and Salmonella choleraesuis. Among the 14 cases of patients, 5 cases of Salmonella choleraesuis, 3 cases of Salmonella typhimurium, with the positive rate of 57.14% (8/14). One case of environment and two cases of food were detected. The result of PFGE showed nine PFGE types, 95.00% homology for 7 strains, and 94.00% homology for 4 strains. Conclusions The food poisoning was caused by eating egg fried rice containing Salmonella choleraesuis and pork intestine containing Salmonella typhimurium. In the future, , it is necessary to strengthen the risk monitoring of food contamination and harmful factors, to ensure food safety from the source of food supply, and to prevent the occurrence of foodborne infection events. At the same time, it is also crucial to standardize the health check of related personnel, and to conduct multi-channel education on the harm and prevention of foodborne diseases.
