Since May 2022, multinational monkeypox outbreak has become the largest monkeypox outbreak in history outside Africa. This review summarizes progress in the etiology, epidemiology, laboratory detection, clinical diagnosis and treatment of monkeypox.

Objective:To study the effect of various concentrations of Enterococcus faecalis (Ef) supernatants on human periodontal ligament cell (hPDLC) and the inflammatory response of hPDLC under static pressure. Methods:The method of methyl thiazolyl tetrazolium (MTT) was used to detect the effect of various concentrations of Ef supernatants on the proliferation of hPDLCs and the flow cytometry was used to detect the expression of Toll-like receptor 2 (TLR-2) on the surface of hPDLC after 24-hour-stimulation of Ef supernatant. Furthermore, the hPDLCs were divided into non inducing group without Ef supernatant and inducing group with 5% Ef supernatant, and hPDLCs in each group were loaded with 0, 49 and 196 Pa static pressures respectively. The expressions of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) mRNA and protein were detected by reverse transcription-PCR (RT-PCR) and enzyme linked immunosorbent assay (ELISA) after 24 hours.Results:MTT results showed that the supernatant of Ef with concentratio n≥5% could significantly inhibit the proliferation activity of hPDLCs at 48 hours of cell culture ( P<0.05). Flow cytometry showed that the positive cell rates of TLR-2 increased with increasing volume fractions of the Ef supernatants. The values were (2.12±0.07)%, (2.41±0.32)%, (2.65±0.27)%, (4.76±0.46)%, (9.91±0.92)% and (12.01±1.35)%, respectively. The differences were statistically significant when the concentrations≥5% ( P<0.05). There were no significant differences in the expressions of IL-1β and TNF-α mRNA between the non inducing group and the control group under the pressure of 49 Pa ( P>0.05). However, there were significant differences in the expressions of IL-1β and TNF-α mRNA between the non inducing group and the control group under the pressure of 196 Pa ( P<0.05), while the expressions of IL-1β and TNF-α in the inducing group were significantly lower than that in the control group under the pressures of 49 and 196 Pa ( P<0.05). Compared with the control group, the mRNA expression was significantly increased ( P<0.05). The result of ELISA was consistent with that of PCR. Conclusions:High concentration of Ef supernatant could inhibit the proliferation of hPDLC. Ef supernatant might promote the expression of TLR-2 on the surface of hPDLC. Excessive mechanical pressure induced the inflammatory response of hPDLC. The presence of inflammatory mediators could lead to the intolerance of hPDLC to pressures and small pressure could aggravate the inflammatory response.

To prepare virus-like particles containing FluA/B mRNA as RNA standard and control in Influenza RNA detection, the genes coding the coat protein and maturase of E. coli bacteriophage MS2 were amplified and cloned into D-pET32a vector. Then we inserted 6 histidines to MS2 coat protein by QuikChange Site-Directed Mutagenesis Kit to construct the universal expressing vector D-pET32a-CP-His. In addition, the partial gene fragments of FluA and FluB were cloned to the down-stream of expressing vector. The recombinant plasmid D-pET32a-CP-His-FluA/B was transformed to BL21 with induction by IPTG. The virus-like particles were purified by Ni+ chromatography. The virus-like particles can be detected by RT-PCR, but not PCR. They can be conserved stably for at least 3 months at both 4 degrees C and -20 degrees C. His-tagged virus-like particles are more stable and easier to purification. It can be used as RNA standard and control in Influenza virus RNA detection.

Objective To examine the effects of IL-10 on cardiac fibroblasts ( CFBs) proliferation and phenotype transformation to myofibroblasts (MyoFbs) induced by transforming growth factor-β1 (TGF-β1);and to investigate the regulating pathways .Methods Cardiac fibroblasts were isolated from cardiac ventricles of neonatal SD rats . The passage 2~4 were used and divided into the following groups for treatment:1) control group, 2) IL-10 reac-tion group, 3) TGF-β1 reaction group, and 4) IL-10 plus TGF-β1 reaction group (TGF-β1 treatment followed with IL-10 pretreatment ) .Cells proliferation was assessed by MTT assay and immunocytochemistry staining for prolifera-ting cell nuclear antigen (PCNA);the phenotype transformation into MyoFbs was assessed by immunocytochemistry of α-smooth muscle actin (α-SMA);extracellular signal related kinase ( ERK1/2) and P38 kinase pathways were assessed by western-blot.Results TGF-β1 (10 μg/L) treatment boosted the proliferation and the expression ofα-SMA significantly (P<0.01), while IL-10 (10, 50 or 100 μg/L) plus TGF-β1 co-treatment induced lower cell proliferation and expression of α-SMA than treating with TGF-β1 alone ( P<0.05 ) , with the inhibitory effect of IL-10 being concentration dependent .TGF-β1 could significantly stimulate the ERK 1/2 and P38 kinase phospho-rylation ( P<0.01 ) , however IL-10 (100 μg/L) plus TGF-β1 co-treatment failed to down-regulated the phospho-rylation of ERK1/2 and P38 kinase compared with TGF-β1 alone ( ERK1/2:P<0.05;P38:P<0.01 ) .Conclu-sions IL-10 can attenuate TGF-β1-induced CFBs proliferation and phenotype transformation to MyoFbs .The in-hibitory effects may explained by a mechanism of inhibiting the activation of ERK 1/2 and P38 kinase .
