The number of antigen-specific T lymphocytes secreting IFN-γ and IL-4 (213.7±0.6 and 311.7±1.5) in the Sot group induced by mice was significantly higher than that in the So group (94.3±16.8 and 185.7±4.2) ( P<0.001). The serum antibody level induced by Sot group was higher than that in the So group, the geometric mean titer (GMT) of neutralizing antibodies against BA.2 strain were 588 and 337, respectively ( P<0.05). Sot protein induced Th1/Th2 mixed type immune response with the predominance of Th2 type. Conclusions:The protein subunit vaccine expressed by the prokaryotic system have excellent cellular and humoral immunogenicity, which provides a strong theoretical basis for the development of the protein subunit vaccines of the SARS-CoV-2 Omicron variant.

Objective:To analyze the whole genome sequence and key site mutations of hepatitis B virus (HBV) in patients with different stages of disease progression, and to understand the relationship between HBV genetic characteristics and disease progression.Methods:Serum samples and basic information of hepatitis B patients with asymptomatic HBV carrier, chronic hepatitis B patients, cirrhosis patients and primary hepatocellular carcinoma patients were collected. Nested PCR was used to amplify the samples to obtain HBV whole gene sequences. Phylogenetic trees were constructed to determine the genotype of the samples, and gene mutations of the samples were analyzed combined with reference sequences of each type.Results:A total of 256 samples were successfully amplified, including 68 asymptomatic HBV carrier patients, 118 CHB patients, 15 LC patients and 55 HCC patients, and five genotypes (B, C, D, I and C/D) were detected. The result of comparative analysis showed that the mutation rate of 56 nucleotide sites was significantly different among the four groups ( P<0.05). In addition to the discovery of C105T, A1762T/G1764A and G1899A and other previously reported key site mutations, the mutation rates of T53A, C1485T and C1628T in newly diagnosed HCC group were significantly higher than those in other groups, and the mutation rates of T2150G and T2151C in asymptomatic HBV infection group were significantly higher than those in other groups. A total of 26 sequences were deleted, mainly distributed in the pre-C and pre-S regions. The deletion mutation rate in the HCC group was significantly higher than that in the other groups. Conclusions:The data of this study indicate that some nucleotide substitution mutations and deletion mutations may be closely related to the occurrence and development of HBV-related diseases, and HCC patients are more likely to have gene mutations than non-HCC patients. These result provide a reference for understanding the relationship between viral mutation and the progression of HBV infection-related diseases.

Objective:To evaluate the prognosis of patients with primary thyroid malignant lymphoma (PTL) treated with total thyroidectomy alone or in combination with R-CHOP chemotherapy, and analyze the factors influencing their prognosis.Methods:A retrospective analysis was conducted on 62 patients with PTL admitted to the Hematology Department of Shanxi Provincial Cancer Hospital from Jan. 2009 to Jan. 2020. The patients were with an average age of (63.51±9.83) years, with 20 males and 42 females. According to Ann Arbor staging and patients' wishes, 10 cases received simple thyroidectomy, 47 cases received total thyroidectomy +R-CHOP, and 5 cases received total thyroidectomy +R-CHOP+ radiotherapy. After 3 months of treatment, the short-term curative effect was collected. According to the prognosis of patients after 24 months of follow-up, the dead cases were classified into bad group and the surviving cases into good group. Single factor and LASSO regression dimensionality reduction were used to screen the influencing factors, and Logistic regression analysis was used to analyze the influencing factors of PTL prognosis.Results:Among 62 patients with PTL, 21 (33.87%) had complete response (CR), 27 (43.55%) had partial response (PR), 9 (14.52%) had stable disease (SD), and 5 (8.06%) had progressive disease (PD). After a follow-up of 24 months, the mortality rate among 10 patients who underwent surgical treatment alone was 90% (9/10), the mortality rate among those who underwent surgical treatment combined with R-CHOP therapy was 19.15% (9/47) ,18 deaths were categorized as having a poor prognosis, while 44 survivors were classified as having a favorable prognosis.Univariate, LASSO regression screening, and Logistic regression analysis showed that Ann Arbor staging ( OR=5.105), pathological type ( OR=3.622), international prognostic index (IPI) score ( OR=2.709), treatment method ( OR=0.730), hemoglobin ( OR=0.392), and lactate dehydrogenase (LDH) ( OR=6.469) were factors affecting the prognosis of PTL (all P<0.05) . Conclusions:The combined use of total resection and R-CHOP treatment for patients has a superior prognosis compared to patients undergoing total resection alone. Furthermore, the prognosis of patients is also influenced by factors such as Ann Arbor staging and IPI scoring. Based on this, clinical care plans can be refined to improve the prognosis.

Multiple myeloma (MM) is a malignancy characterized by clonal proliferation of plasma cells that infiltrate the bone and soft tissues, and is the second most common hematological malignancy in many countries. Currently, there is no cure for this disease, as the bone marrow microenvironment serves as a sanctuary for MM cell growth. The interaction between the bone marrow microenvironment and MM cells collectively promotes the occurrence and progression of MM. Immune cells in MM cells and the microenvironment induce immune imbalance through complex interactions, ultimately leading to tumor initiation and development. Therefore, in-depth research on the tumor microenvironment is of significant importance for the treatment of MM. This review discusses the research progress of MM bone marrow microenvironment from the aspects of tumor microenvironment, interaction between tumor microenvironment and MM, and immunotherapy.
