Objective:
To analyze the microvessel density (MVD) and lymph node metastasis in the papillary thyroid carcinoma (PTC) with punctate or sheet calcification.
Methods:
Fifty PTC patients in the Affiliated Hospital of Yangzhou University from May 2015 to October 2017 were retrospectively enrolled in this study. All of the 50 PTC patients were divided into punctate calcification group (38 cases) and sheet calcification group (12 cases) according to the different features of pathological calcification in microscope examination. For the two groups, the central and peripheral zone MVD and the lymph node metastasis of each PTC nodule were compared.
Results:
For PTC nodules of punctate calcification group, the mean central and peripheral zone MVD were (51±7)/HP and (64±8)/HP, respectively. For those of sheet calcification group, which were (35±5)/HP and (49±6)/HP, respectively. The mean MVD in both central and peripheral zone of PTC nodules of punctate calcification group were significantly higher than those of the sheet calcification group (t values were 10.183 and 12.406, both

ObjectiveTo observe the intervention effect of Fufang Kangjiaolv capsules on anxiety-like behaviors in the rat model of chronic restraint stress (CRS) and explore the mechanism underlying the anti-anxiety effect via the microbiota-gut-brain axis. MethodsRats were assigned into blank, model, positive drug (diazepam, 1 mg·kg-1), and low-, medium-, and high-dose (0.75, 1.5, 3 g·kg-1, respectively) Fufang Kangjiaolv capsules groups. After 14 days of administration, the elevated plus maze test, open field test, light and dark box test, and marble burying test were performed. Hematoxylin-eosin staining was employed to observe the pathological changes in the hippocampus and colon of rats, and Nissl staining was conducted to observe the damage of hippocampal neurons. The gut microbiota was analyzed by 16S rRNA gene sequencing. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was employed to determine the mRNA levels of zonula occludens-1 (ZO-1) and occludin in the colon of rats. The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) in the colon, serum, and hippocampus were determined by enzyme-linked immunosorbent assay. Western blot was employed to determine the protein levels of ZO-1, occludin, nuclear factor-κB p65 (NF-κB p65) in the colon tissue and NF-κB p65 and brain-derived neurotrophic factor (BDNF) in the hippocampal tissue. ResultsCompared with the blank group, the model group showed reductions in the time and frequency ratio of rats entering the elevated plus maze, the time and frequency of rats entering the central area of the open field, the time of entering the open box, the times of passing through the light and dark box, and the number of unburied beads (P<0.05, P<0.01). Compared with the model group, Fufang Kangjiaolv capsules ameliorated the anxiety of the model rats to varying degrees, and the high-dose group had the best effect, with increases in the proportions of time and frequency of rats entering the open arm in the elevated plus maze (P<0.05), the number of rats entering the central area in the open field (P<0.05), the time of entering the open box, the times of passing through the light and dark boxes, and the number of unburied beads (P<0.01). Moreover, the high-dose group showed alleviated pathological damage of hippocampal neurons and colon. The results of 16S rRNA gene sequencing showed that the model group had increased relative abundance of Firmicutes, Deferribacterota, Romboutsia, and Phascolarctobacterium, while it had decreased relative abundance of Bavcteroidota and Lactobacillus. The drug administration groups showed increased relative abundance of Bavcteroidota, Bacteroides, norank f norank o Clostridia UCG-014, and Blautia and decreased relative abundance of Firmicutes and Deferribacterota. Compared with the blank group, the model group showed down-regulated protein and mRNA levels of ZO-1 and occludin in the colon (P<0.01), elevated levels of TNF-α, IL-6, and IL-β in the colon, serum, and hippocampus (P<0.01), up-regulated protein level of NF-κB p65 in the colon and hippocampus (P<0.01), and down-regulated protein level of BDNF in the hippocampus (P<0.05). Compared with the model group, high-dose Fufang Kangjiaolv capsules up-regulated the mRNA levels of ZO-1 and occludin in the colon (P<0.01), lowered the levels of TNF-α, IL-6, and IL-β in the colon, serum, and hippocampus (P<0.01), up-regulated the protein levels of ZO-1 (P<0.01) and occludin (P<0.05) in the colon, down-regulated the protein level of NF-κB p65 in the colon and hippocampus (P<0.05), and up-regulated the protein level of BDNF in the hippocampus. ConclusionFufang Kangjiaolv capsules can reduce the anxiety-like behaviors in the rat model of CRS by regulating the gut microbiota disturbance, up-regulating the expression of tight junction proteins in the colon, repairing intestinal mucosal mechanical barrier, and down-regulating NF-κB/BDNF signaling pathway, thereby reducing peripheral and central inflammation. This study proves the hypothesis that Fufang Kangjiaolv capsules play an anti-anxiety role via the microbiota-gut-brain axis, providing a new idea for further research.

Emerging SARS-CoV-2 variants have made COVID-19 convalescents susceptible to re-infection and have raised concern about the efficacy of inactivated vaccination in neutralization against emerging variants and antigen-specific B cell response. To this end, a study on a long-term cohort of 208 participants who have recovered from COVID-19 was conducted, and the participants were followed up at 3.3 (Visit 1), 9.2 (Visit 2), and 18.5 (Visit 3) months after SARS-CoV-2 infection. They were classified into three groups (no-vaccination (n = 54), one-dose (n = 62), and two-dose (n = 92) groups) on the basis of the administration of inactivated vaccination. The neutralizing antibody (NAb) titers against the wild-type virus continued to decrease in the no-vaccination group, but they rose significantly in the one-dose and two-dose groups, with the highest NAb titers being observed in the two-dose group at Visit 3. The NAb titers against the Delta variant for the no-vaccination, one-dose, and two-dose groups decreased by 3.3, 1.9, and 2.3 folds relative to the wild-type virus, respectively, and those against the Omicron variant decreased by 7.0, 4.0, and 3.8 folds, respectively. Similarly, the responses of SARS-CoV-2 RBD-specific B cells and memory B cells were boosted by the second vaccine dose. Results showed that the convalescents benefited from the administration of the inactivated vaccine (one or two doses), which enhanced neutralization against highly mutated SARS-CoV-2 variants and memory B cell responses. Two doses of inactivated vaccine among COVID-19 convalescents are therefore recommended for the prevention of the COVID-19 pandemic, and vaccination guidelines and policies need to be updated.
