bstract: Objective To elucidate the distribution characteristics of mosquito species and the population genetic
diversity of important mosquito species in the Wuyi Mountain Nature Reserve, with the aim of providing a scientific basis for
the prevention and control of mosquito-borne diseases in the region. Methods Within Wuyi Mountain Nature Reserve 2022-
2023, 16 sampling sites were selected, where larvae were collected using the pipette method and adult mosquitoes were
collected using the mosquito trap lamp method. Mosquito species identification was accomplished by integrating morphological
characteristics and molecular identification techniques based on CO Ⅰ and CO Ⅱ gene sequences. Software tools such as
ClustalX, DnaSP v5.0, and Network v4.6.1.0 were utilized to analyze the genetic differentiation (Fst), gene flow (Nm) among
populations of Aedes japonicus, Aedes albopictus and Armigeres subalbatus. Results The mosquito specimens collected from
the Wuyi Mountain Nature Reserve were identified as 30 species belonging to 8 genera within the Culicidae family. Among
them, there were 10 species of Aedes, 13 species of Culex, 1 species each of Armigeres, Orthopodomyia, Uranotaenia,
Tripyeroides, and Anopheles, and 2 species of Toxorhynchites. Analysis of the genetic structure of important mosquito
populations showed that the haplotype diversity index (Hd) of Ae. japonicus was 0.994 7, with a generally moderate degree of
differentiation between populations and a higher degree of genetic differentiation between populations 6 and 12; Aedeslbopictus had a haplotype diversity index of 0.634 0, with significant genetic differentiation between populations 1 and 2
compared to other groups; Armigeres subalbatus had a haplotype diversity index of 0.703 3, with substantial genetic
differentiation and limited gene flow between population 2 and populations 3, 4, 6, and 7. Conclusions The mosquito species
are rich in Wuyi Mountain Nature Reserve. A comprehensive survey of the composition and distribution of mosquito populations
was carried out, and the characteristics of the population genetic structure of the important species of Ae. japonicus, Ae.
Albopictus, and Ar. subalbatus populations were analyzed, providing valuable scientific data reference for local mosquito-borne
ecological research and disease prevention and control.

Although previous studies have shown functional efficacy of myelotomy for the treatment of spinal
cord injury (SCI), the underlying mechanism remained unknown. This study aimed to determine
the relationship between myelotomy-mediated neuroprotection and autophagy following SCI by
evaluating the expression of microtubule-associated protein light chain 3 (LC3-II) and mammalian
target of rapamycin complex 1 (mTORC1). Ninety-nine adult female rats were randomly assigned
to either sham-operated group (SG), model group (MG), or 24 h-myelotomy group (MTG). SCI at
T10 was induced with a New York University impactor, and myelotomy was performed 24 h after
SCI. Functional recovery was evaluated via the open-field test. The protein expression of LC3-II
was analyzed by Western blot, and the mRNA expression of LC3-II and mTORC1 were detected by
real-time quantitative reverse transcriptase polymerase chain reaction. Rats in the MTG exhibited
significantly better performance in the hind limbs compared to those in the MG on day seven and
fourteen post-injury. Myelotomy suppressed the protein and mRNA expression of LC3-II on day three,
seven and fourteen post-injury and increased the mRNA expression of mTORC1 in the MTG on day
three and seven post-injury. The LC3-II protein expression was significantly and negatively correlated
with BBB scores at day seven and fourteen post-injury. These results showed that myelotomy-induced
neuroprotection in a rat model of SCI was likely mediated by inhibition of autophagy by activation
of the mTORC1 signaling pathway

Objective:To investigate the clinicopathological characteristics of acidophil stem cell pituitary neuroendocrine tumors (PitNET)/adenoma.Methods:Five cases of acidophil stem cell PitNET/adenoma were diagnosed between May 2022 and July 2023 at the Second Hospital of Hebei Medical University, Shijiazhuang, China. The clinicopathological features of the tumor were analyzed by using histology, immunohistochemistry, and electron microscopy. The relevant literature was reviewed.Results:There were 1 male and 4 females, aged from 23 to 69 years. Patient 3 was 55 years old at the time of diagnosis and first surgery, and relapsed 5 years later. The patients′ median age was 32 years. Patients 1 and 5 showed elevated blood prolactin, with various degrees of hormonal symptoms except Patient 3, who showed only tumor compression symptoms. Imaging studies showed that all cases involved the sellar floor. The tumors of Patients 1, 2 and 5 were closely related to the cavernous sinus segment of the internal carotid artery. The tumors exhibited a diffuse growth pattern with chromophobic to slightly acidophilic cytoplasm. A few of tumor cells showed chromophobic cytoplasm. The nucleoli were conspicuous. Intranuclear inclusion bodies and variably-sized clear vacuoles were observed occasionally. Under electron microscope, marked mitochondrial abnormalities were observed, including increased mitochondria number, expanded hypertrophy, and absence of mitochondrial ridge fracture. Some mitochondrial matrices were dense, while some were vacuolated.Conclusions:Acidophil stem cell PitNET/adenoma is a rare type of pituitary adenomas/PitNETs. It often has a more clinically aggressive manner with immature cells, diffuse expression of PIT1, prolactin, and varying degrees of growth hormone expression. Because of the obvious diversity of their clinical hormone status and hormone immune expression, the diagnosis of this type tumor is still a challenge.

Objective:To observe the ratio of helper T cells 17 (Th17)/regulatory T cells (Treg) in peripheral blood of patients with Hashimoto's thyroiditis (HT) and the expression changes of related cytokines in serum, and to explore their role in the occurrence and development of HT.Methods:Using the case-control study method, 35 HT patients examined in the General Hospital of Heilongjiang Beidahuang Group from February to November 2019 were selected as HT group, and 39 healthy people in the same period were selected as control group. Early morning fasting venous blood samples of the two groups were collected to test the levels of thyroid stimulating hormone (TSH), free thyroxine (FT 4), thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TgAb). The expressions of serum interleukin (IL)-6, IL-17 and transforming growth factor β (TGF-β) were tested by enzyme-linked immunosorbent assay (ELISA); the number of Th17, Treg in peripheral blood were determined by flow cytometry. Results:The levels of TPOAb, TgAb and TSH in HT group [130.60 (43.37, 714.40), 368.10 (136.90, 1 103.00) U/ml, 9.05 (6.62, 15.23) μU/ml] were significantly higher than those in control group [2.66 (1.52, 4.69), 12.63 (11.43, 14.60) U/ml, 1.87 (1.36, 2.23) μU/ml, U = 6.87, 6.62, 4.85, P < 0.001], and the FT 4 level [0.76 (0.63, 1.04) ng/dl] was lower than that in control group [1.14 (1.02, 1.26) ng/dl, U = 7.39, P < 0.001]. The expressions of IL-6, IL-17 and TGF-β in HT group were higher than those in control group ( t = 2.41, 9.04, 2.44, P < 0.05). The number of Th17 and the ratio of Th17/Treg in HT group were higher than those in control group ( t = 4.20, 3.50, P < 0.05), and the number of Treg was lower than that in control group ( t = 4.45, P = 0.001). Conclusion:In HT patients, Th17 are increased, Treg decreased, Th17/Treg ratio increased, and the expressions of IL-6, IL-17 and TGF-β are increased.
