Abstract: Objective To analyze and compare the effects of different clinical characteristics on the negative conversion time of nucleic acid detection after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infection, and to provide a scientific basis for the isolation and treatment of coronavirus disease 2019 (COVID-19). Methods The epidemiological and clinical data of 228 mild SARS-CoV-2 Omicron variant infected patients diagnosed in Shanghai were retrospectively collected from April 27, 2022 to June 8, 2022 in Wujiaochang designated Hospital, Yangpu District, Shanghai. The negative conversion time of nucleic acid detection was used as the outcome variable, and the patients were divided into A (≤18 days) and B (>18 days). Univariate and multivariate logistic regression analysis were used to analyze the influencing factors of the negative conversion time of nucleic acid detection. Results The mean nucleic acid conversion time of 228 patients was (18.7±12.1) d, with the median time of 18 (2-46) d. Among them, 120 patients in group A had an average nucleic acid conversion time of (13.2±2.0) d, and 108 cases in group B had an average nucleic acid conversion time of (20.8±1.3) d. Univariate analysis showed that there were no statistically significant differences in the effects of hypertension, coronary heart disease, diabetes, hypokalemia, malignant tumors, neuropsychiatric diseases, chronic digestive diseases on the negative nucleic acid conversion time (P>0.05); however, there were significant differences in the effects of combined cerebrovascular disease, leukopenia, chronic respiratory system diseases and vaccination on the negative nucleic acid conversion time (P<0.05). Further multivariate logistic regression analysis revealed that the combination of chronic respiratory diseases and non-vaccination were significant risk factors for prolongation of negative nucleic acid conversion time (P<0.05). Conclusions The results of this study show that gender, age and whether hypertension, coronary heart disease, diabetes mellitus, hypokalemia, malignant tumor, neuropsychiatric disease and chronic digestive disease have no significant effect on the nucleic acid conversion time, whereas chronic respiratory disease and no vaccination are significantly correlated with the prolongation of nucleic acid conversion time in SARS-CoV-2 Omicron-infected patients.

OBJECTIVEThe protection rate of inoculation with BCG vaccine is only 50 percent, and most of patients with tuberculosis had a history of BCG vaccine inoculation. Adenosine (ADO) has an immunomodulating effect; it promotes immune reaction by increasing number of macrophage and enhancing phagocytosis. The present study was designed to investigate if combined use of adenosine with BCG enhances the anti-Mycobacterium tuberculosis effect of macrophage in mice.
METHODSFifty BALB/C mice were divided randomly into 3 groups: BCG group (n = 21), BCG plus ADO group (n = 21) and control group (n = 8). The mice in BCG and BCG plus ADO groups were inoculated with 0.1 ml BCG intradermally and the mice in BCG plus ADO group were injected intraperitoneally with ADO 30 mg/(kg.d) for 5 days. The mice in BCG group and control group were injected with NS 0.1 ml/d for 5 days. Six weeks after the last injection, all mice were challenged with intravenous 1 x 10(6) CFU human Mycobacterium tuberculosis virulent strain. After challenging, lung and spleen specimens were taken at the 10th, 20th and 30th days from the mice of BCG and BCG plus ADO groups and at the 30th day from mice in control group. The pathological examinations of lung and spleen sections were performed after HE staining and acid-fast staining, and detection of cell apoptosis was also performed.
RESULTSConsolidation with neutrophil infiltration was found in most of the lung tissue taken at the day 30; there were a lot of tuberculous granulomas and Mycobacterium tuberculosis in the lungs of control group. The alveolar septum in BCG gradually became wide and in interstitium lymphocyte infiltration dominated, and there were less tuberculous granulomas but there were large number of Mycobacterium tuberculosis in the lungs from 10th to 30th days after challenging. The widening of alveolar septum and consolidation of lung tissue in BCG plus ADO group became milder with monocytes infiltration, and there were few tuberculosis granulomas and Mycobacterium tuberculosis in the lungs from 10th to 30th days after challenging.
CONCLUSIONADO could increase the number of monocyte-macrophages and promoted anti-bacterial effects of these cells.

Objective To analyse the subtype and transmission of HIV strain in both HIV infected spouses. Methods Reported both HIV infected spouses were selected as objects. Analysis on genetic sequence and high risk behaviors was carried out. Subgenomic gag was amplified by nest-PCR analysis of whole blood samples from objects. Genetic subtype characterization of HIV was identified and pairwise genetic distances were calculated. Sequence relationships were also examined by phylogenetic tree analysis. Results Genetic sequences of 46 pairs (92 cases) were obtained. The genetic subtype comprised 39 CRF01_AE(42.4%), 10 CRF07_BC(10.9%), 18 CRF08_BC (19.6%),18 B (19.6%) ,5 C (5.4%) and 2 CRF02_AG(2.2%). 44 pairs had the same subtype between the two partners, accounted for 95.7% of the total. 33 of the 41 pairs with phylogenetic tree analysis were found having epidemiological linkage in pair wise. Sexual behaviors of out-marriage were the main risk factors of CRF01_AE and CRF08_BC and CRF02_AG strains infection. Blood transmission was associated with B and CRF07_BC. Conclusion The HIV strains subtype detected in HIV infected spouses characterized with diversity. CRF01_AE was the main strain subtype. The main route of transmission to the spouses was through unprotected sexual contacts. Surveillance programs on HIV infected partner together with intervention between the spouses should be improved.
