Cataract is still the main blinding eye disease,and it is a major goal of fighting blindness in China.In the past years,the diagnosis,treatment technology and equipment have made great progress.With the further understanding of this disease and increasing requirement of patients for the quality of life,the standardization,safety and efficacy of the clinical diagnosis and surgical outcomes of cataract have become much more important.So the relative clinical examination approaches,modified operating skills,new surgery development and application as well as novel type of functional IOLs design advance rapidly,which provide an expensive space for the selection of the treatment for cataract.High quality of cataract surgery depends on preoperative precise biometry,reasonable operating scheme targeting at personality,suitable functional IOL,less intra-or post-operative complications,effectively avoiding treatment risk and correctly processing disadvantageous factors affecting postoperative visual quality.Therefore,the management of cataract surgery is a systemic procedure.The issue of improving ophthalmic examination,new cataract surgical technique and new IOL emerges as the time requires.How to make up individual-based treatment options for patients,better improve postoperative visual quality,enhance the safety of operative procedure,reduce operative complications is the challenges and unremitting goal for the ophthalmologists.

Abstract Traditional Chinese medicine (TCM) auscultation has a long history, and with advancements in equipment and analytical methods, the quantitative analysis of auscultation parameters has determined. However, the complexity and diversity of auscultation, along with variations in devices, analytical methods, and applications, bring challenges to its standardization and deeper application. This review presents the advancements in auscultation equipment and systems, auscultation characteristic parameters, and their application in the diagnosis of pulmonary diseases and syndromes over the past 10 years, while also exploring the progress and challenges of current digital research of auscultation. This review also proposes the establishment of standardized protocols for the collection and analysis of auscultation data, the incorporation of advanced artificial intelligence (AI) auscultation analysis methods, and an exploration of the diagnostic utility of auscultatory features in pulmonary diseases and syndromes, so as to provide more precise decision support for intelligent diagnosis of pulmonary diseases and syndromes

Objective To analyze the influences of lacrimal secretion and tear film after interferon-alpha therapy in patients with chronic viral hepatitis.Methods Sixty patients with chronic viral hepatitis who would accept the interferon-alpha therapy,including 30 cases of hepatitis B and 30 chronic viral hepatitis C,visited our department of ophthalmology and were enrolled in this study.All cases received eye examination,including medical history,slit lamp examination,corneal fluorescein staining ( FL) ,tear film break-up time ( BUT) and schirmer test before inter-feron-alpha therapy and two months after the therapy.Results In the 60 cases of chronic viral hepatitis,there were 19 dry eye cases (31.67%) and 41 non-dry eye cases (68.33%).In dry eyes group,9 of them (47.37%) were hepatitis B patients and 10 of them were hepatitis C patients (52.63%) .There was significant difference in FL grade (t=-5.288,P<0.05),BUT (t=5.799,P<0.05),Schirmer Ⅰ(t=5.319,P<0.05) test in hepatitis B before and two months after interferon-alpha therapy.Statistical significance had been found before and two months after therapy in FL grade (t=-9.103,P<0.05),BUT (t=5.682,P<0.05),SchirmerⅠtest (t=4.592,P<0.05). The incidence of dry eye syndrome in hepatitis B patients increased from 26.70%to 53.30%two months after treated with interferon-alpha,while the incidence of dry eye syndrome in hepatitis C patients increased from 33.30% to 60.00% two months after treated with interferon-alpha.Conclusion Dry eye syndrome is one of common complica-tions in patients with chronic viral hepatitis.Interferon-alpha therapy would influence the lacrimal secretion and dam-age tear film,which increased the dry symptoms in patients.We should pay attention to the side effects of interferon-alpha therapy.

Aim: To study the effects of astragaloside IV on experimental ventricular remodeling in mice and its mechanism from matrix metalloproteinase aspect.Method: Ventricular remodeling in mice was induced by con-secutively subcutaneous injection of isoproterenol for 14 days.Astragaloside IV(40,80 mg/kg)and propranolol(40 mg/kg,positive control)were administered by gavage to mice.Echocardiography was used to observe the left ventricular end diastolic diameter(LVIDd),left ventricular end systolic diameter(LVIDs),fractional shortening(FS)and ejection fraction(EF).The myocardial pathological pattern was detected by HE staining.Expressions of matrix metalloproteinases(MMP2,MMP9)and tissue inhibitor of metalloproteinases(TIMP1,TIMP2)mRNA in myocardium were detected by RT-PCR.Activities of MMP2 and MMP9 were assayed by zymography.Results:Compared with those of control mice,LVIDd and LVIDs were increased,FS and EF were decreased in the model group.Myocardial injury and fibrosis existed in histop at hological slices of the model group.In addition,the mRNA expressions and activities of MMP2 and MMP9 were increased in the model group.However,there were no markable changes to TIMP1 and TIMP2.Treatment with astragaloside IV reduced LVIDd and LVIDs,increased FS and EF,attenuated myocardial injury,and down-regulated mRNA expressions and activities of MMP2 and MMP9 compared with the model group.Conclusion: Astragaloside IV can greatly improve ventricular remodeling and dysfunction via decreasing MMP2 and MMP9 mRNA expression and activities in cardiac ventricles.

Objective To investigate early and differential diagnosis of Alzheimer disease and vascular dementia (VD)using FDG-PET scan. Methods Clinical data was collected from AD,VD and normal control(NC). 18F-2-fluo-ro-deoxy-D-glucose(18F-FDG)PET scan was conducted to detect the cerebral FDG metabolism. The average standard uptake value (SUV) of cerebral regions was expressed as semiquantitative index relative to ipsilateral cerebellum. Re-sults There were no differences in age and the mean total scores of the mini mental status examination (MMSE) between patients with VD and those with AD.The AD group showed that the SUV was significantly decreased in the right frontal, parietal,temporal lobe,hippocampus,temporo-parietal junction,and bilateral posterior cingulate cortex compared to the VD and in the bilateral posterior cingulate cortex,temporo-parietal junction,frontal and temporal lobe comparing to the NC(P≤0.01). SUV was significantly increased in the right parietal,posterior cingulate cortex and hippocampus whereas was significantly decreased in the left frontal lobe,temporo-parietal junction and thalamus in the VD compared with NC group(P≤0.01). Conclusion AD patients have typical features of 18F-FDG PET which may be helpful for the diagnosis of AD in the early stage.

Objective To investigate the staphylococcal chromosomal cassette mec (SCCmec)genotypes and molecular epidemi-ology of hospital-acquired MRSA.Methods A total of 26 non-duplicate MRSA isolates with the same resistant pattern were studied.SCCmec genotyping was analyzed by multiplex PCR.Repetitive element polymerase chain reaction (Rep-PCR)tech-nique was used to analyze the homology between these strains based on the DiversiLab system.Results The most common geno-type of these MRSA strains was SCCmec-III (84.6%).Two strains belonged to SCCmec-II and 1 SCCmec-IV.SCCmec-I strain was not identified.Based on the results of DiversiLab analysis,these MRSA strains were classified into 10 groups.The genetic similarity ranged from 40% to 100% among these SCCmec types.The two strains of SCCmec-II belonged to the same subtype.The similarity coefficient was higher than 90% for one strain of SCCmec-III subtype 1.The 4 strains of SCCmec-III subtype 3 were grouped into the same set with a similarity coefficient of > 95%.The MRSA strains of SCCmec-III subtype 2 was divided into 5 groups (similarity co-efficient > 90%).Conclusions SCCmec-III is the major genotype of MRSA isolates in our hospital.MRSA strains may spread in some wards.Clinicians and infection control department should pay close attention to this issue.

In the previous study, a high-throughput screening method was established to find the antagonists of CD36. In the present study, a new compound named IMB-1680 was found using this method. The anti-atherosclerotic activities of IMB-1680 were then evaluated. Dose-dependent activities of IMB-1680 were detected by using Sf9 [hCD36] and CHO [hCD36] models. Fluorescence microscopic photography and flow cytometry were used to analyze uptake of mLDL. Foam cell test with RAW264.7 macrophages was used to examine lipid accumulation. The results showed that IMB-1680 inhibited CD36 activity with IC50 of 2.80 and 8.79 micromol x L(-1) in Sf9[hCD36] and CHO [hCD36] cells, respectively. Fluorescence microscopic photography and flow cytometry revealed that IMB-1680 could significantly reduce DiI-AcLDL uptake. Meanwhile, IMB-1680 also could reduce lipids accumulation in RAW264.7 macrophages. In all, the data indicated that IMB-1680 might be a potent effective anti-atherosclerotic leading compound.
