Abstract: Objective　To explore the correlation between monocyte to high-density lipoprotein cholesterol ratio (MHR) and insulin resistance (IR) in male patients with type 2 diabetes mellitus (T2DM) combined with metabolic-related fatty liver disease (MAFLD). Methods A total of 454 male patients with T2DM combined with MAFLD in National Metabolic Management Center (MMC) of the Affiliated Hospital of Jiangsu University from May 2018 to July 2020 were enrolled. The general clinical data of subjects were collected, blood routine and biochemical indexes were tested, homeostasis model insulin resistance index (HOMA-IR) was calculated, visceral fat area (VFA) and subcutaneous fat area (SFA) were measured. Accordingtothe MHR quartile, patients were divided into group Q1 (MHR≤0.38), group Q2 (0.380.64) to compare the differences in measured indicators above. In addition, patients were divided into two groups according to HOMA-IR, HOMA-IR<2.5 and HOMA-IR≥2.5, and the differences in MHR were compared. Results The patients were divided into four groups according to MHR:group Q1 (n=115), group Q2 (n=110), group Q3 (n=120) and group Q4 (n=109). Fasting insulin (FINS) were respectively 6.17(4.20,9.76), 7.73(4.94,10.66), 8.92(5.32,11.33) and 9.13(5.25,12.27) mU/L, 2-hour postprandial insulin were 22.75(12.87,39.59), 27.55(16.44,39.77), 30.98(17.46,43.11) and 31.28(18.54,45.92) U/L. HOMA-IR were 3.12(1.63,4.25), 3.72(2.26,4.66), 3.87(2.48,5.44) and 3.95(2.42,5.31). Neutrophil (Neu) were 3.10(2.60,3.70), 3.20(2.50,3.93), 3.60(2.80,4.28), 4.20(3.30,5.00)×109/L. Subcutaneous fat area (SFA) were (181.27±53.60), (192.64±62.41), (199.53±61.40) and (203.69±71.51) cm2. They all increased gradually. However, the levels of high-density lipoprotein cholesterol (HDL-c) [1.18(1.06,1.35), 1.02(0.86,1.17), 0.96(0.80,1.03) and 0.80(0.69,0.92) mmol/L] and low-density lipoprotein cholesterol (LDL-c) [(3.00±0.79), (2.76±0.83), (2.67±0.85) and (2.59±0.92) mmol/L] decreased gradually. Pearson's or Spearman's correlation analysis showed that MHR was positively correlated with FINS, 2-hour postprandial insulin (2hINS), HOMA-IR, VFA and SFA (r=0.190, 0.153, 0.184, 0.114, 0.127, P<0.05). The coronary heart disease history, systolic blood pressure,diastolic blood pressure,fasting plasmaglucose (FPG), FINS, alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood uric acid (Ur), body mass index (BMI), VFA, SFA and MHR of patients in group HOMA-IR≥2.5 were higher than group HOMA-IR<2.5 (P<0.05). Conclusion　MHR is positively correlated with IR in male patients with T2DM combined with MAFLD, and as MHR increases, the degree of IR is higher.

Compound 1 is a new glycoside naphthopyranone compound. The anti-hepatitis B virus (HBV) activity of these compounds was evaluated. The EC₅₀ and CC₅₀ of compound 3 against HBV were 4.5 μmol·L^-1 and 92.3 μmol·L^-1, respectively. This is the first report of the antiviral activity of compound 3.

Objective To investigate the trend of antimicrobial resistance and the prevalence of resistant genes in Pseudomonas aeruginosa strains isolated from Hangzhou First People's Hospital.Methods Antimicrobial susceptibilities of 1489 Pseudomonas aeruginosa strains isolated from 2003 to 2007 were statistically analyzed using WHONET.MICs of 11 antimicrobisis to 36 multi-drug-resistant Pseudomonas aerugionosa strains were determined by agar dilution method.Genes of β-lactamases(BLA)and aminoglycoside-modifying enzymes(AMEs)were detected by PCR and the PCR products were sequenced.Results The resistant rates to aztreonam,imipenem,ceftazidime,cefepime,piperacillin,piperacillin/tazobactam.cefoperazone/sulbactam,ciprofloxacin,levofloxacin,gentamicin and amikacin were increased from 13.4%,10.6%,8.7%,7.9%,12.7%,12.7%,6.7%, 15.8%,20.5%,24.7% and 10.9%in 2003 to 35.3%,40.9%,18.4%, 32.4%,32.9%,32.0%,21.9%,37.8%,38.6%, 39.4% and 34.8% in 2007.respectively.Hish MICs of 11 antimicrobiMs for multi-drug resistant Pseudomonas aerouginosa were determined with MIC90≥128 μg/mL.In 36 multi-drug resistant Pseudomonas aeruginosa strains,21(58.3%)strains carried β-lactamase genes and 32 strains(88.9%)carried aminoglycosidemodifying enzyme genes,while the deletion rate of oprD2 was 80.6%(29/36).Conclusions The resistant rates to common antibiotics of Pseudomonas aeruginosa have increased.resulting in multi-drug resistance.Genes of β-lactamases and aminoglycoside-medifying enzymes are prevalent in multi-drug resistant Pseudomonas aeruginosa strains,with the common deletion of oprD2.

Objective To identify lesion patterns and stroke mechanisms in middle cerebral artery (MCA) territory using early diffusion-weighted imaging (DWI) combined with CTA as well as EKG and echocardiography.Methods One hundred and forty-eight acute ischemic stroke patients who had (1) symptomatic lesions located in the unilateral MCA territory on DWI performed within 1 week of symptom onset,and (2) either corresponding MCA disease,internal carotid artery (ICA) disease,MCA & ICA disease or cardio embolism (CE),or (3) neither corresponding MCA disease,ICA disease,nor CE which were taken as group of negative results (NR),were reviewed.Acute DWI lesion patterns were classified as (1) single (small perforator < 2 cm;large perforator ≥2 cm;pial;large territorial;border-zone) and (2) multiple according to principle of single-blind.Results There were 12 types of lesions in MCA territory.Distribution of lesion patterns in different stroke subtypes might be different (χ2= 55.88,P = 0.004).No specific pattern could be found in patients with MCA disease,ICA disease,MCA & ICA disease or CE.Big perforator infarcts might be more common in patients with MCA disease than with ICA disease and CE.Compared with negative group,concomitant perforator and pial infarcts were more common in patients with ICA disease (7/27,χ2=6.61,P <0.05),especially with severe stenosis or occlusion (5/16,χ2=7.32,P < 0.05);No specific pattern could be found in patients with MCA disease or CE.Concomitant perforator,pial,with border-zone infarcts (6/30,χ2= 6.41,P <0.05),and concomitant perforator with border-zone infarcts (4/30,χ2= 5.59,P < 0.05) were more often in patients with severe stenosis or occlusion of MCA.Conclusion Different lesion patterns may indicate different mechanisms of stroke such as hypoperfusion and arterial embolism could be coexistent in MCA territory.The relationship has not been identified perfectly.

Trachoma, a contagious keratoconjunctivitis ( KC ) , caused by Chlamydia trachomatis infection, is rife in 57 countries in the world at present. The World Health Organization ( WHO) listed the global alliance to eliminate blinding trachoma by 2020 as one of top priorities of its blindness prevention in 1998. A simplified classification system for identifying and naming trachoma, designated by WHO, and the SAFE strategy based on community intervention were extended continuously in the world in 10 years since then. The trachoma prevalence trend has showed a change compared with that in the past. China has launched the blindness prevention action, aimed to eliminate blinding trachoma by 2016. In this paper, we reviews progress in diagnosis, treatment and epidemic of trachoma since the extension of the SAFE strategy.

To establish a method of directional differentiation and efficient production of neurons from embryonic stem cells (ES cells) in vitro, based on the 4-/4+ protocol described by Bain, a new method was established to induce ES cells differentiating into neurons by means of three-step differentiation using all-trans retinoic acid (ATRA) combined with astrocyte-conditioned medium (ACM) in Vitro. The totipotency of ES cells was identified by observation of cells' morphology and formations of teratoma in immunocompromised mice. The cells' differentiation was evaluated continuously by the detection of the specific cellular markers of neural stem cells, neurons and astrocytes, including nestin, NSE and GFAP using immunohistochemistry assay. The NSE positive cells' ratio of the differentiated cells was determined by flow cytometry. It was found that the transparent circular clusters surrounding embryoid bodies induced with combining induction protocol formed just after 24 h and gradually enlarged later. This phenomenon could not be observed in EBs induced only by ATRA. The NSE positive cells' ratio in the cells induced with ATRA and ACM was higher than that of the cells induced by ATRA at different time points of differentiation, and finally reached up to 73.5% among the total differentiated population. It was concluded that ES cells could be induced into neurons with high purity and yield by means of inducing method combining with ATRA and ACM.
