[Objective]To explore the relationship between peripheral arterial disease(PAD)and diabetic retinopathy(DR)in type 2 diabetes patients.[Methods]A total of 99 patients diagnosed with PAD were classified into grade 1-3 by their total scores of peripheral arterial stenosis assessed by color doppler ultrasound examinations,where the degree of stenosis 30% ~ 49% scored 0, 50%~99%scored 1,lumen occlusion(i.e. degree of stenosis 100%)scored 2,and therefore the total score 0-2 was categorized into Grade 1 ,3~4 into Grade 2 ,5~12 into Grade 3. The bilateral anterior tibial artery ,posterior tibial artery and dorsalis pedis artery of these patients were analyzed. The presence of diabetic retinopathy(DR)was graded from retinal photographs using a standard protocol.[Results]Among 99 cases of type 2 diabetic patients with peripheral arterial disease ,58.6%of them were male with average age of 67.3 ± 7.9 years old. Patients of Grade 1,Grade2,Grade 3 lesion accounted for 45.4%,30.3%,24.2%,respectively. Age, gender,smoking history,SBP,DBP,BMI,FBG,TC,TG,LDL-C,HDL-C,HbA1C among 3 groups were not statistically signifi-cant. The associations of DM duration and HbA1C value were significantly larger in DR than in PAD. The proportion of DR patients increased with the severity degree of PAD(p for trend=0.004). Degree of stenosis Grade 2 and Grade 3 could be predictive for DR.[Conclusions]DR is associated with the severity degree of PAD in type 2 diabetes patients as evaluated by duplex ultrasonography.Degree of stenosis Grade 2 and 3 could be used for screening or finding DR. Strategies for optimum treatment and early prevention are needed.

Malaria is one of the major diseases threatening the lives of people in Africa. Over the past decade, China has provided anti-malaria assistance to Africa. In November 2007, fast control malaria team of Guangzhou University of Chinese Medicine cooperated with the Comoros health authority. In Moheli Island of the Comoros, the anti-malaria team adopted a new strategy of Mass Drug Administration (MDA) and active intervention. They established an effective anti-malaria system and reporting system, as well as a local anti-malaria team. Furthermore, they treated patients with malaria in Moheli Island and implemended health education in local people. In a very short time, they have achieved remarkable results. This paper summarized the experiences of the project in order to provide useful reference for China to better carry out anti-malaria action in Africa and expand foreign health assistance.

Objective:To analyze the distribution of pathogenic bacteria in bile culture in patients with common bile duct stones and biliary tract infections, in order to guide clinical optimization of antibiotics application.Methods:From March 30, 2017 to December 31, 2021, at Affiliated Hospital of Qingdao University, 753 patients with common bile duct stones and biliary tract infections and received endoscopic retrograde cholangiopancreatography were selected. Bile samples were obtained for bacterial culture, strain type identification and drug sensitivity test in order to analyze bile pathogenic bacteria distribution, change trend and drug resistance. Chi-square test was used for statistical analysis.Results:From 2017 to 2021, the total positive rate of bile culture in 753 patients with choledocholithiasis complicated with biliary tract infection was 90.17% (679/753). From 2017 to 2021, the positive rates of bile culture were 82.05% (64/78), 88.81% (119/134), 88.03% (125/142), 93.87% (199/212), and 91.98% (172/187), respectively, and the difference was statistically significant ( χ2=10.78, P=0.029). The positive rate of bile culture in 2017 was lower than those in 2020 and 2021, and the differences were statistically significant ( χ2=9.43 and 5.57, P=0.002 and 0.018). There were no significant differences in the positive rates of bile culture among the other years (all P>0.05). A total of 1 033 pathogenic bacteria were detected in the 679 bile specimens with positive bile culture results. Among which the total proportion of Gram-negative bacilli was 57.02% (589/1 033), and from 2017 to 2021 the proportions were 66.38% (77/116), 66.47% (111/167), 59.43% (104/175), 54.75% (173/316), and 47.88% (124/259), respectively. The total proportion of Gram-positive cocci was 41.05% (424/1 033), and from 2017 to 2021 the proportions were 31.90% (37/116), 31.74% (53/167), 38.86% (68/175), 44.30% (140/316), and 48.65% (126/259), respectively. The total proportion of fungus was 1.94% (20/1 033), and from 2017 to 2021 the proportions were 1.72% (2/116), 1.80% (3/167), 1.71% (3/175), 0.95% (3/316), and 3.47% (9/259), respectively. From 2017 to 2021, the proportion of Gram-negative bacilli gradually decreased, while the proportion of Gram-positive cocci gradually increased, and the differences were statistically significant ( χ2=20.14 and 17.91, P<0.001 and =0.001). From 2017 to 2021, the change in the proportion of fungus was not statistically significant ( P>0.05). The main Gram-negative bacilli in the bile culture were Escherichia coli (31.36%, 324/1 033) and Klebsiella pneumoniae (12.68%, 131/1 033); the main Gram-positive cocci were Enterococcus faecalis (14.04%, 145/1 033) and Streptococcus salivarius (4.36%, 45/1 033). From 2017 to 2021, the proportions of Escherichia coli were 39.66% (46/116), 38.92% (65/167), 33.14% (58/175), 28.48% (90/316), and 25.10% (65/259), respectively, with gradual decrease and the difference was statistically significant ( χ2=14.34, P=0.006). From 2017 to 2021 the detection rates of extended-spectrum β-lactamase (ESBL) in Escherichia coli and Klebsiella pneumoniae were 30.43% (14/46), 26.15% (17/65), 29.31% (17/58), 38.89% (35/90), 40.00% (26/65), and 4/15, 20.00% (5/25), 20% (5/25), 24.32% (9/37), and 31.03% (9/29), and there were no significant differences in the detection rates of ESBL between different years (both P>0.05). Conclusions:From 2017 to 2021, the positive rate of bile culture in patients with choledocholithiasis complicated with biliary tract infection showed an overall increasing trend. Gram-negative bacilli were still dominated in bile pathogenic bacteria, while the proportion of Gram-positive cocci remarkably increased, and the bile bacterial spectrum significantly changed. Clinicians should adjust the antibiotic dosing regimens according to the variation of bacterial spectrum and drug resistance.

Objective:We sought to investigate the clinical characteristics and risk factors of antiphospholipid syndrome (APS) complicated by autoimmune hemolytic anemia (AIHA).Methods:Retrospective anaysis.Three hundred fifteen consecutive patients with APS were enrolled at the Department of Rheumatology of Peking Union Medical College Hospital between May 2017 to May 2021, and their clinical manifestations[including initial symptoms, time interval between APS onset and diagnosis, systemic lupus erythematosus(SLE), thrombotic events, obstetric morbidity, and extra-criteria manifestations] and laboratory test results[including blood routine, antiphospholipid antibodies(aPLs), blood lipid profile, homocysteine, anti-nuclear antibody profile, immunoglobulin levels, and complement levels] were collected. Then, univariate and multivariate logistic regression analyses were performed. Clinical features and risk factors were analyzed using univariable and multivariable logistic regression analysis.Results:Among 315 APS patients, 37 cases (11.7%) were complicated by AIHA, and AIHA was the first manifestation or co-occurrence. The median time interval between APS onset and diagnosis was 12 months. The proportion of SLE in APS patients combined with AIHA was higher than that in APS patients without AIHA[62.2%(23/37) vs. 19.4%(54/278), P<0.001]. There was no significant difference in the proportions of thrombosis and pregnancy morbidity between the two groups. In terms of extra-criteria manifestations, APS patients with AIHA had a significantly ( P<0.05) greater risk of thrombocytopenia ( OR=6.19, 95% CI 2.81-13.65) and higher proportions of hypocomplementemia, a positive lupus anticoagulant (LA) result, double aPLs positivity[i.e., any two of the following antibodies were positive: LA, anticardilolipin antibody(aCL), and anti-β2 glycoprotein Ⅰ(β2GPⅠ)], and triple aPLs positivity (i.e., LA, aCL, and anti-β2GPⅠ antibodies were all positive). Multivariate logistic regression analysis showed that SLE ( OR=3.46,95% CI 1.60-7.48), thrombocytopenia ( OR=2.56,95% CI 1.15-5.67), and hypocomplementemia ( OR=4.29,95% CI 2.03-9.04) were independent risk factors for the complication of APS. In the primary APS subgroup, multivariate logistic regression analysis showed that livedo reticularis ( OR=10.51,95%CI 1.06-103.78), thrombocytopenia ( OR=3.77, 95% CI 1.23-11.57), and hypocomplementemia ( OR=5.92,95% CI 1.95-17.95) were independent risk factors for the complication of APS. Conclusions:AIHA is not rare in APS patients; moreover, it occurs more frequently in APS secondary to SLE and is more likely to present with a variety of extra-criteria manifestations. Patients with AIHA should be promptly tested for antiphospholipid antibody profiles and alerted to the possibility of thrombotic events.
