Sweat pores function is the ascending and descending of Qi. The human body maintains a continuous, holistic, and dynamic balance through the functioning of sweat pores as well as the Qi movement and transformation in the spleen, stomach, and triple energizer. Sweat pores play a crucial role in the generation and development of Zang-fu organs, essence and spirit, and body and orifices, as well as in the onset and progression of diseases. Oxidative stress significantly affects the regulation of inflammation in allergic rhinitis(AR), induces the pathological damage to nasal epithelial cells, and alters immune activity, serving as a key mechanism exacerbating AR symptoms. This mechanism closely aligns with the pathogenesis associated with dysfunction in the sweat pore-Qi-triple energizer system. In recent years, oxidative stress and antioxidants in AR have received increasing attention. Elevated levels of reactive oxygen species, fractional exhaled nitric oxide, and malondialdehyde have become key indicators for the early diagnosis of AR. Classical prescriptions, empirical prescriptions, and newly developed preparations of traditional Chinese medicine(TCM) for external use with anti-inflammatory, anti-allergic, and immune-regulatory effects via antioxidant pathways have demonstrated definite efficacy in treating AR. This provides a basis for understanding the pathogenesis of AR in TCM from a modern medical perspective. Therefore, this paper systematically examines the relationship between the sweat pore-Qi-triple energizer system and AR, incorporating the oxidative stress mechanism into the research on pathogenesis of the disorders. Furthermore, methods for treating AR in children are proposed with TCM preparations for external use which aimed at opening nasal sweat pores, dispersing, searching, channeling with aroma, warming, and dredging, regulating Qi movement in spleen, warming Yang Qi to promote urination, and clearing latent wind to inhibit liver depression.

This study explores whether the current external quality assessment (EQA) level and acceptable bias for basic semen analysis in China are clinically useful. We collected data of semen EQA from Andrology laboratories in the Hunan Province (China) in 2022 and searched for data in the published literature from January 2000 to December 2023 in China. On the basis of these data, we analyzed the coefficients of variation and acceptable biases of different quality control materials for basic semen analysis through robust statistics. We compared these findings with quality specifications based on biological variation from optimal, desirable, and minimum levels of bias to seek a unified and more suitable semen EQA bias evaluation standard for China's national conditions. Different sources of semen quality control material exhibited considerable variation in acceptable biases among laboratories, ranging from 8.2% to 56.9%. A total of 50.0% of the laboratories met the minimum quality specifications for progressive motility (PR), whereas 100.0% and 75.0% of laboratories met only the minimum quality specifications for sperm concentration and total motility (nonprogressive [NP] + PR), respectively. The Z value for sperm concentration and PR+NP was equivalent to the desirable performance specification, whereas the Z value for PR was equivalent only to the minimum performance specification. This study highlights the feasibility of operating external quality assessment schemes for basic semen analysis using quality specifications based on biological variation. These specifications should be unified among external quality control (EQC) centers based on biological variation.

Objective:To explore the clinical application value of single pass scanning using muti-slice spiral CT for polytrauma patients.Methods:Totally 60 polytrauma patients treated from January to November in 2023 were randomly enrolled in this study. They were categorized into an experimental group and a control group using a random number table, with 30 patients in each group. The patients in the experimental group underwent single pass scaning for the head, neck, chest, and abdomen, whereas those in the control group receiving separate scanning for various parts. Then, the noise, signal-to-noise ratio (SNR), and contrast-to-noise (CNR) of the CT images of both groups were recorded. Furthermore, the objective and subjective evaluation, volume CT dose index (CTDI vol), effective dose ( E), scanning time, and scan ranges of the images were compared between both groups. Results:Compared to the control group, the test group exhibited lower SNR of the head ( t = -5.47, P < 0.05) and higher SNR and CNR of the chest scans ( t = -5.95, -6.15, P < 0.05). Furthermore, the test group demonstrated decreased ED, CTDIvol, scanning time, and scan range, which dropped from 18.53 mSv to 13.81 mSv ( t = 3.29, P < 0.001), from 15.77 mGy to 10.59 mGy ( t = 4.48, P< 0.001), from 31.68 s to 10.97 s ( t = 6.95, P < 0.001), and from 64.92 cm to 45.21 cm ( t = 9.05, P < 0.001), respectively compared to the control group. Conclusions:Single pass CT scanning can reduce E, scanning time, and scan range in the treatment of polytrauma patients while ensuring the high quality of CT images, thus warranting wide clinical applications.

On the basis of the laboratory detection results of influenza viruses in Jiangsu Province from 2022 to 2023,this study was aimed at conducting a analysis of the genetic characteristics and resistance of the H3N2 influenza virus,and evalua-ting the effectiveness of vaccines and drugs.The full genome of 29 H3N2 isolates submitted by provincewide influenza surveil-lance network laboratories was amplified and sequenced.Phylogenetic trees of the HA and NA genes were constructed.The mutation characteristics of antigenic sites,glycosylation sites,and resistance sites were analyzed,and the influenza virus neura-minidase was detected with a fluorescence luminescence method.The homology of the 29 H3N2 isolates in Jiangsu Province was relatively high.The isolates belonged to the same evolutionary branch as domestic reference strains and the 2021-2022 vaccine strains,but were in different evolutionary branches from foreign reference strains and the 2022-2023 vaccine strains.Compared with the 2021-2022 vaccine strain A/Cambodia/e0826360/2020,the H3N2 influenza viruses isolated in Jiangsu Province during 2022-2023 had four amino acid substitutions in the HA protein and two amino acid substitutions in the NA protein.No changes in glycosylation sites,receptor-binding sites,and conserved amino acid residue regions were observed.IC50 analysis indicated that the 29 H3N2 isolates were not resistant to the antiviral drugs oseltamivir and zanamivir.The pre-dominant influenza viruses detected in Jiangsu Province during 2022-2023 were type A H3N2 influenza viruses.Monitoring of variations in HA and NA gene sites and influenza virus resistance aids in rapid understanding gene mutations,and can inform the selection of effective vaccine strains,and contribute to the prevention and control of influenza virus outbreaks.

Objective To detect the expression of vacuolar protein sorting-associated protein 33A(VPS33A)in the peripheral blood of elderly patients with pulmonary tuberculosis,and explore its correlation with clinical prognosis.Methods A total of 95 elderly pulmonary tuberculosis patients admitted to Macheng City People's Hospital from February 2019 to February 2021 were collected as the research group,and 90 healthy subjects in the same period were selected as control group.The expression of VPS33A and Toll like receptor 2(TLR2)in peripheral blood was detected by real-time fluorescent quantitative PCR(qRT-PCR),and the level of interleukin-6(IL-6)in peripheral blood was detected by enzyme-linked immunosorbent assay.Patients with pulmonary tuberculosis were given standardized anti-tuberculosis regimen therapy(2HRZE/4HR)treatment,and they were followed up for 12 months.According to their prognosis,they were divided into good prognosis group(n=58)and bad prognosis group(n=37).The predictive value of VPS33A for poor prognosis was analyzed by ROC curve.The correlation between serum VPS33A,IL-6 and TLR2 in poor prognosis group was analyzed by Pearson method.Logistic regression analysis was used to explore the factors influencing poor prognosis in elderly patients with pulmonary tuberculosis.Results Compared with the control group,VPS33A level(0.87±0.22 vs 1.02±0.23)in peripheral blood was lower,but IL-6(22.13±5.36 pg/ml vs 18.53±4.68 pg/ml)and TLR2 levels(1.26±0.25 vs 0.99±0.21)were higher in the pre-treatment study group,with significant differences(t=6.170,6.682,11.241,all P＜0.05).Compared with the pre-treatment study group,VPS33A level(0.95±0.25)in peripheral blood was higher,but IL-6(19.66±5.44 pg/ml)and TLR2 levels(1.11±0.2)were lower in the post-treatment study group,with significant differences(t=3.336,4.648,6.331,all P＜0.05).The level of VPS33A(0.71±0.16)in peripheral blood of poor prognosis group was lower than that of good prognosis group(0.97±0.22),while the levels of IL-6(26.41±7.16 pg/ml)and TLR2(1.35±0.26)were higher than those of good prognosis group(19.40±4.21pg/ml,1.20±0.24),with significant differences(t=5.555,6.012,2.875,all P＜0.05).Pearson correlation analysis showed that VPS33A in the pre-treatment study group was negatively correlated with IL-6 and TLR2 levels(r=-0.649,-0.634,all P＜0.05).ROC curve analysis results showed that the AUCs of VPS33A,IL-6 and TLR2 for predicting the prognosis of tuberculosis in the elderly were 0.805,0.842 and 0.882,respectively.The combined AUC of the three was 0.971,which was higher than that predicted by the three alone(Z=4.010,3.136,2.285,P=0.001,0.002,0.022).Logistic regression analysis showed that VPS33A,IL-6 and TLR2 were the influencing factors for poor prognosis of elderly pulmonary tuberculosis patients(all P＜0.05).Conclusion The expression of VPS33A is down-regulated in the peripheral blood of elderly patients with pulmonary tuberculosis,which may be a good predictive value for the prognosis of elderly patients with pulmonary tuberculosis,and be a factor affecting bad prognosis.

In order to promote the innovative application of Sanjiao theory and Yingwei theory， this paper tries to apply the ''Sanjiao-Yingwei'' Qi transformation theory to the treatment of tumor diseases， integrating it with T cell exhaustion mechanism to elaborate on its scientific connotation and using network pharmacology and bioinformatics to elucidate the correlation between the anti-tumor mechanism of ''Sanjiao-Yingwei'' Qi transformation and T cell exhaustion. The ''Sanjiao-Yingwei'' Qi transformation function is closely related to the immunometabolic ability of the human body， and the ''Sanjiao-Yingwei'' Qi transformation system constitutes the immunometabolic exchange system within and outside the cellular environment. Cancer toxicity is generated by the fuzzy Sanjiao Qi， and the long-term fuzzy Sanjiao Qi is the primary factor leading to T cell exhaustion， which is related to the long-term activation of T cell receptors by the high tumor antigen load in the tumor microenvironment. Qi transformation malfunction of the Sanjiao produces phlegm and collects stasis， which contributes to T cell exhaustion and is correlated with nutrient deprivation， lipid accumulation， and high lactate levels in the immunosuppressed tumor microenvironment， as well as with the release of transforming growth factor-β and upregulated expression of programmed death receptor-1 by tumor-associated fibroblasts and platelets in the tumor microenvironment. Ying and Wei damage due to Sanjiao Qi transformation malfunction is similar to the abnormal manifestations such as progressive loss of exhausted T cell effector function and disturbance of cellular energy metabolism. Guizhi decoction， Shengming decoction， and Wendan decoction can correct T cell exhaustion and exert anti-tumor effects through multi-target and multi-pathways by regulating ''Sanjiao-Yingwei'' Qi transformation， and hypoxia inducible factor-1α （HIF-1α） may be one of the main pathways to correct T cell exhaustion. It was found that HIF-1α may be one of the important prognostic indicators in common tumors by bioinformatics. The use of the ''Sanjiao-Yingwei'' Qi transformation method may play an important part in improving the prognosis of tumor patients in clinical practice.

Exosome is a kind of extracellular vesicles secreted by cells to the outside. Biogenesis mainly involves two invaginations of the cytoplasmic membrane, the formation of multivesicular bodies, and the release of exosomes. Exosomes have abundant and diverse inclusions—including landmark membrane proteins, soluble proteins, various RNA molecules and DNA fragments, etc. Cells can achieve intercellular signal communication by secreting and receiving exosomes. Through interaction of ligand molecules on the exosome membrane with receptors on the surface of other cytoplasmic membranes, exosomes can activate cell signal transduction or fuse with the cell membrane to release its contents into the cytoplasm to exert regulatory functions. In the central nervous system, exosomes secreted by neurons and various glial cells can mediate wired synaptic signal transmission, but mainly play a role similar to neuromodulator by way of volume transmission. In this paper, the biogenesis of exosomes and important functional components are described in detail, and the characteristics of neural exosomes in the biogenesis, content sorting and controlled release are compared with those of synaptic vesicles. We further review the research progress on the physiological functions of neural exosomes on the central nervous system and their roles in the occurrence and development of neurodegenerative diseases and major depressive disorder. We also prospect the application of exosomes in the early diagnosis and targeted therapy of nervous system diseases.
