Objective:To analyze the consistency between MT-9000 and IOLMaster 700 in measuring preoperative ocular biometric parameters in patients with age-related cataracts.Methods:A cross-sectional study was conducted.A total of 536 patients (536 eyes) were consecutively included and scheduled for cataract extraction combined with intraocular lens implantation at Aier Eye Hospital of Wuhan University from June 20 to August 22, 2024.Two visualized sweep-frequency biometers, MT-9000 and IOLMaster 700, were used to measure the biometric parameters of all the patients.The parameters including axial length (AL), white to white (WTW), anterior chamber depth (ACD), lens thickness (LT), central corneal thickness (CCT), and mean keratometry (Km). The AL detection rates of the two instruments were compared, as were the differences in above parameters, and the correlation and consistency of the measurements were analyzed.Patients were divided into three groups based on AL measured by MT-9000: a short axis group (AL<22 mm) comprising 27 eyes, a normal axis group (22≤AL≤25 mm) comprising 392 eyes, and a long axis group (AL>25 mm) comprising 104 eyes.The differences in measured AL in different subgroups were compared.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Aier Eye Hospital, Wuhan University (No.2024IRB06017). Written informed consent was obtained from each subject.Results:The AL detection rate measured by MT-9000 was 99.3% (532/536), higher than 97.6% (523/536) measured by IOLMaster 700, with a statistically significant difference ( χ2=4.841, P=0.028). MT-9000 AL, LT and Km measurements were all higher than IOLMaster 700 measurements, showing statistically significant differences ( Z=6.418, t=4.971, 5.179; all P<0.001). WTW and CCT measurements from MT-9000 were both lower than those from IOLMaster 700, showing statistically significant differences ( Z=-3.017, t=16.322; both P<0.05). After grouping based on AL measurements from MT-9000, there was no statistically significant differences in AL measurements between MT-9000 and IOLMaster 700 in the short axis group and the normal axis group ( Z=-1.530, P=0.126; t=-0.880, P=0.380). In the long axis group, the AL measured by MT-9000 was longer than that by IOLMaster 700, with a statistically significant difference ( Z=7.254, P<0.001). The intra-class correlation coefficient values of AL, WTW, ACD, LT, CCT, and Km measured by MT-9000 and IOLMaster 700 were 1.000, 0.616, 0.997, 0.999, 0.988, and 0.995 (all P<0.001), respectively.The 95% limits of agreement (LoA) of AL, WTW, ACD, LT, CCT, and Km measured by Bland-Altman analysis were -0.06-+ 0.08 mm, -0.64-+ 0.57 mm, -0.06-+ 0.06 mm, -0.04-+ 0.05 mm, -13.6-+ 6.3 μm and -0.26-+ 0.32 D, respectively, which had 6.5%, 3.6%, 5.3%, 6.3%, 6.5% and 4.4% of the data points outside the 95% LoA. Conclusions:MT-9000 shows favorable agreement with IOLMaster 700 in the measurement of AL, ACD, LT, CCT and Km.MT-9000 is suitable for preoperative biometrics measurement in cataract patients.However, the agreement between the two devices is not desirable in the measurement of WTW, and interchangeable use of these two devices is not recommended in this regard.Additionally, MT-9000 outperforms IOLMaster 700 in terms of AL detection rate.

Objective:To analyze the effect of meridian scraping combined with thunder fire moxibustion in improving the motor function and hemorheology of patients with shoulder hand syndrome (SHS) after ischemic stroke, in order to provide reference for clinical intervention of SHS patients after ischemic stroke.Methods:A prospective study was conducted using a simple random sampling method to select SHS patients after ischemic stroke admitted to Shijiazhuang Hospital of Traditional Chinese Medicine from January 2020 to June 2023, and were randomly divided into two groups. The thunder-fire moxibustion group were given routine nursing and thunder-fire moxibustion therapy, and the combined group were additionally given scraping therapy along meridians on the basis of thunder-fire moxibustion group. The Upper Limb Fugl-Meyer Motor Function Assessment Scale (U-FMA) score, Visual Analogue Scale (VAS) score, Action Research Arm Test (ARAT) score, shoulder joint activity score, hemorheological indicators (hematocrit, plasma viscosity, platelet adhesion rate) and activities of daily living (Barthel Index), etc. were compared between two groups before and after intervention.Results:Finally, 86 patients with SHS after ischemic stroke were included, with 42 patients in the thunder-fire moxibustion group, including 25 males and 17 females, aged (59.37 ± 7.64) years; 44 patients in the combined group, including 24 males and 20 females, aged (59.52 ± 7.61) years. Before intervention, there was no statistical significance in U-FMA score, VAS score, ARAT score, shoulder joint activity score, hemorheology index level and Barthel Index between two groups (all P>0.05). After intervention, the U-FMA score, ARAT score and Barthel Index in the combined group were (48.21 ± 4.85), (40.22 ± 4.64), (56.43 ± 9.76) points, respectively, which were higher than (44.56 ± 4.23), (35.98 ± 4.37), (51.97 ± 8.31) points in the thunder-fire moxibustion group, the differences were statistically significant ( t =3.71, 4.36, 2.28, all P<0.05). The VAS score, shoulder joint mobility score, blood cell volume, plasma viscosity and platelet adhesion rate in the combined group were (2.44 ± 0.87) points, (1.23 ± 0.25) points, 0.44 ± 0.02, (1.35 ± 0.32) mPa·s, (53.56 ± 5.71)%, respectively, which were lower than (3.05 ± 0.99) points, (1.58 ± 0.22) points, 0.46 ± 0.02, (1.72 ± 0.36) mPa·s, (62.53 ± 5.94)% in the thunder-fire moxibustion group, the differences were statistically significant ( t values were 3.04-7.14, all P<0.05). Conclusions:Scraping along meridians combined with thunder-fire moxibustion therapy can achieve good intervention effect in patients with SHS after ischemic stroke, improve the upper limb motor function and hemorheology of patients, and enhance the activities of daily living.

Intestinal microorganisms and their metabolites are involved in the pathogenesis and progression of various cardiovascular diseases,especially in the progression of heart failure.This paper mainly discussed the gut microbial metabolites trimethylamine oxide(TMAO)participated in the pathological process of heart failure,and application value of TMAO in heart failure patients.This paper introduced the change characteristics of intestinal flora and its metabolites in heart failure patients,illu-minated the TMAO-mediated inflammatory response,and the related signal pathways and mechanism of myocardial hypertrophy and heart failure.High levels of TMAO are associated with poor outcomes in patients with heart failure indicating a good predictive value for the prognosis of heart failure.Regulating TMAO levels through diet,probiotics and prebiotics,antibiotics,fecal transplan-tation,and other pathways is expected to be a potential treatment for heart failure.

Objective To analyze the current situation and characteristics of risk factors in antithrombotic therapy(in-cluding antiplatelet and anticoagulant treatments)at home and abroad,and to provide a theoretical basis for the prevention and treatment of thrombosis or bleeding associated with antithrombotic therapy.Methods The literature on risk factors of an-tithrombotic therapy published in Chinese databases(China Journal Full-text Data,Wanfang Database,VIP Database)and Eng-lish databases(PubMed,Web of Science,MEDLINE)from January 2011 to November 2021 was searched and bibliometric analy-sis was performed.The visualization analysis was performed using VOS viewer software.Results A total of 595 publications were included in the analysis.The top three countries for English publications were the USA,China,and Japan.The type of stud-ies were predominantly cohort studies,with sample sizes mostly being below 1 000.Risk factors for antithrombotic therapy are cat-egorized into those affecting antiplatelet drugs,warfarin,and new oral anticoagulants.Age,gender,renal function,and combination of antithrombotic drugs are common risk factors,and different risk factors of antithrombotic drugs also have their characteristics.Conclusion While there is substantial research on risk factors in antithrombotic therapy globally,the sample size needs to be improved.Pharmacists should provide individualized medication services based on different drugs and different groups to ensure medication safety for patients.

Objective To investigate the application of MRI T2*-mapping in the early damage of the medial meniscus posterior root(MMPR)in asymptomatic knee osteoarthritis(OA).Methods Eighty subjects were included in this study,35 were diagnosed with knee OA(OA group)and clinically confirmed MMPR injury,35 were asymptomatic OA group with gender and age matching,and 10 were normal control group.All subjects were examined by T2*-mapping.The T2*-mapping values at the bone attachment,middle part,and 1 cm bone attachment point of MMPR were measured in each group,and the consistency of T2*-mapping values between the knee OA group and the asymptomatic OA group was verified by the Kappa test.The T2*-mapping values of each measurement area were statistically compared,and the clinical diagnosis accuracy and other indicators of the T2*-mapping parameter values were statistically analyzed.Results The Kappa value of the knee OA group and the asymptomatic OA group analyzed by T2*-mapping was 0.787(P＜0.01),Kappa statistical analysis showed that there was a good consistency between the two diagnostic results.The T2*-mapping values of the knee OA group,asymptomatic OA group,and normal control group at the bone attachment,middle part,and 1 cm bone attachment point of MMPR showed that the T2*-mapping values of each measurement area in the knee OA group and asymptomatic OA group were higher than those in the normal control group(P＜0.05).The T2*-mapping values of the knee OA group were higher than those of the asymptomatic OA group,and the difference was statistically significant(P＜0.05).While the T2*-mapping values were used in the asymptomatic OA group to diagnose the early damage of MMPR,the sensitivity,specificity,accuracy,negative predictive value,and positive predictive value were 89.6％,88.9％,91.1％,87.5％,and 88.3％respectively.Conclusion T2*-mapping value may be used as a reference index to predict the progression of knee OA,and has a certain value in the early diagnosis of asymptomatic OA MMPR injury.

Objective To explore the clinical application of two endometrial mechanical stimulation methods in patients with repeated implantation failure (RIF) in frozen-thawed embryo transfer (FET) cycle. Methods A total of 127 women with RIF who planned to perform FET again were included. They were separated into 3 groups: Group A (45 cases) with endometrial scratching and group B (42 cycles) with endometrial sucking within menstrual period in FET cycle, while in control group C (40 cases), no endometrial mechanical stimulation was performed. The outcomes of pregnancy were compared. Results The endometrial types of endometrial scratching group were mainly type A. The embryo implantation rate and clinical pregnancy rate in group A (27.27%, 46.67%) were significantly higher than those in group B (12.75 %, 21.43%) and group C (11.46%, 20.0%) (P <0.05). Conclusion The endometrial mechanical stimulation can improve the endometrial receptivity, compare with endometrial sucking, endometrial scratching can improve the clinical pregnancy rate of RIF patients more obviously.

OBJECTIVE To investigate the effects of obstructive sleep apnea hypopnea syndrome on the quality of life of the patients. METHODS The quality of life was assessed with the Medical Outcomes Study SF-36 Health Survey in 145 patients with OSAHS and 17 snorers without OSAHS. Excessive Daytime Sleepiness was assessed with Epworth Sleepiness Scale. Pearson linear correlation and stepwise multiple regression analysis were used to study the association between each domain score of SF-36 and patients information,PSG parameters,EDS scores. RESULTS Three domains of SF-36 correlated negatively with Body Mass Index. Four domains correlated negatively with EDS. Three domains and total score correlated significantly with the lowest oxygen saturation. Two domains correlated negatively with the longest time of apnea. AHI and the lowest oxygen saturation have a mild side effect on the quality of life. BMI and EDS score have significantly side effect on the quality of the life. CONCLUSION Comparing to the mild OSAHS patients and snorers without OSAHS,the severe OSAHS patients have worse quality of life. EDS score and BMI have a significantly side effect on the severe OSAHS patients. OSAHS has a side effect on the quality of life of the patients.

An efficient BASIC program was established on Apple-Ⅱ microcomputer with the CHESTAC-3EF pulmonary function testing system to calculate the time-constant histogram from the spirogram.By a set of analogue studies, we confirmed that the recovered time-constant histogrgram was within one compartment of the assumed one and that the root of mean square values of the residuals between the experimental and model volume-time curves was 0.02. In four adult healthy subjects, the mean value of time-constant histograms (TCx ) had the variation coefficient (6.6%). The results show that our method is reliable and reproducible, and it can be used for clinical investigation.
