Objective:To explore the skin conditions, skin diseases, and physiological functions of the facial skin in plateau children.Methods:It was a cross-sectional study. A total of 327 children aged 6-12 years which included 164 males (9.97±2.56 years) and 163 females (10.23±2.05 years) were recruited in this study from six different altitude groups from June 2022 to February 2024 at the Department of Dermatology, the First Affiliated Hospital of Kunming Medical University: Yongren group, Kunming group, Meigu group, Dashanbao group, Lashihai group, and Rikaze group at altitudes of 1 500, 1 800, 2 000, 3 100, 3 500, and 3 800 m. and 76, 63, 21, 34, 64, and 69 children were recruited from each group, respectively. The facial skin characteristics and the transepidermal water loss, stratum corneum hydration, the L * value, and the a * value, which were tested by non-invasive instruments, were collected. Subsequently, meteorological data for the six locations were obtained from CNKI and China Meteorological Data Service Centre, including monthly temperature, monthly humidity, and annual sunshine duration. Finally, all data were analyzed using SPSS 29.0. Results:The top five facial skin diseases in 327 children were telangiectasia (249, 82.57%), freckles (173, 52.91%), nevus (125, 38.23%), pityriasis alba (98, 29.97%), and scars (93, 28.44%). In addition, a total of 15 cases of melasma with a lower score of mMASI were identified in this study. In all the subjects, 7.65% had severe desquamation, 19.57% had moderate desquamation, and 40.98% had mild desquamation. The whole transepidermal water loss value of highland children＇s face was (6.55±3.95) g·m -2·h -1, the stratum corneum hydration value was (24.19±19.45) au, the L * value was (51.76±4.31) au, the a * value was (15.60±2.29) au. The Dashanbao group was higher than the other 5 groups ( F=18.76, P<0.05), and the stratum corneum hydration of the Lashihai and Rikaze groups was higher than any other groups ( F=157.292, P<0.05), the L * value of the Meigu group was the lowest in any other 5 groups ( F=14.06, P<0.05), the a * value of the Kunming group was lower than other all groups ( F=11.88, P<0.05). Conclusions:The proportion of facial skin diseases varies slightly across altitudes, with significant differences in skin barrier function among the six groups of children with impaired skin barrier function in the highlands.

Factors affecting male fertility include lifestyle,psychology,environment.and so on.Pathogenic microorganisms in the genitourinary system can also lead to decline of male fertility.However,doctors tend to ignore the effects of immune responses and oxidative stress caused by pathogenic microorganisms on fertility,thus delaying the optimal time of treatment.This paper reviews the relationship between bacteria(such as Escherichia coli,Helicobacter pylori),viruses((severe acute respiratory syndrome coronavirus 2,human papilloma virus),and other pathogenic microorganisms(mycoplasma and chlamydia)and male infertility,and summarizes the latest research progress,aiming to provide guidance for the multidimensional treatment and to provide new ideas for the prevention of male infertility.

Objective:To explore the application value of renal artery resistance index in the diagnosist of intra-abdominal hypertension (IAH) in critically ill patients.Methods:89 patients with risk factors of IAH in the intensive care unit of Zhangzhou Hospital Affiliated to Fujian Medical University from February 2022 to June 2022 were retrospective analyzed. The intra-abdominal pressure (IAP) were measured by bladder, and patients divided into IAH group (IAP≥12 mmHg) and non-IAH group (IAP <12 mmHg). The resistance index (RI) of the right renal aorta, segment artery and interlobar artery were measured by color Doppler ultrasound. The difference between the measurement indicators of patients in the IAH and non-IAH groups and the correlation with IAP were analyzed. As for different indicators to predict the diagnostic efficacy of IAH, ROC curve analysis was used to evaluate the effect. And further multivariate logistic regression analysis was to find independent risk predictor.Results:A total of 89 patients were included in the study, including 44 patients with normal IAP and 45 patients diagnosed IAH. There were significant differences in the right renal aorta, segmental artery and interlobar artery RI (all P<0.01). The interlobar artery RI≥0.698 was the highest diagnostic cut-off,area under the curve was 0.914, sensitivity was 82.2%, specificity was 97.7%, and Jordon index was 0.799. The Spearman correlation analysis of IAP and the ultrasonographic measurements revealed a strong correlation between right renal interlobar artery RI and IAP ( r=0.741, P<0.01). The multivariate logistic regression analysis showed that the right renal interlobar artery RI ( OR= 24.472, 95% CI:5.122~116.919, P<0.01) was an independent risk predictor of IAH ( P<0.01). Conclusion:Right renal interlobar artery RI had better diagnostic efficacy of IAH,renal ultrasound could be used as an alternative, non-invasive technique for the diagnosis and follow-up of IAH.

OBJECTIVE: To explore the effect of leucine-rich α-2-glycoprotein (LRG1) derived from hepatocytes on activation of hepatic M1 Kupffer cells. METHODS: A metabolic dysfunction-associated fatty liver disease (MAFLD) model was established in BALB/c mice by high-fat diet (HFD) feeding for 16 weeks. Oleic acid was used to induce steatosis in primary cultures of mouse hepatocytes. The mRNA and protein expressions of LRG1 in mouse liver tissues and hepatocytes were detected by real-time PCR and Western blotting. Primary hepatic macrophages were stimulated with the conditioned medium (CM) from steatotic hepatocyte along with LRG1 or transforming growth factor-β1 (TGF-β1), or both for 24 h, and the expression levels of inducible nitric oxide synthase (iNOS) was detected with Western botting, and the mRNA expressions of iNOS, chemokine ligand 1 (CXCL-1) and interleukin-1β (IL-1β) were measured by RT-PCR. The MAFLD mice were injected with LRG1 (n=6), TGF-β1 (n=6), or both (n=6) through the caudal vein, and the live tissues were collected for HE staining and immumohistochemical detection of F4/80 expression; the mRNA expressions of iNOS, CXCL-1 and IL-1β in liver tissues were detected using RT-PCR. RESULTS: The mRNA and protein expression levels of LRG1 were significantly downregulated in the liver tissues of MAFLD mice and steatotic hepatocytes (P < 0.05). Treatment of the hepatic macrophages with CM from steatosis hepatocytes significantly enhanced the mRNA expression levels of iNOS, CXCL-1 and IL-1β, and these changes were significantly inhibited by the combined treatment with TGF-β1 and LRG1 (P < 0.05). In MAFLD mice, injections with either LRG1 or TGF-β1 alone reduced hepatic lipid deposition and intrahepatic macrophage infiltration, and these effects were significantly enhanced by their combined treatment, which also more strongly inhibited the mRNA expression levels of iNOS, CXCL-1 and IL-1β (P < 0.05). CONCLUSION LRG1 inhibits hepatic macrophage infiltration by enhancing TGF-β1 signaling to alleviate fatty liver inflammation in MAFLD mice.

Immune escape is one of the ten hallmarks of tumors， which plays an important role in the occurrence and development of tumors. Immune escape refers to a process where tumor cells remodel and edit the immune system through the model of immune clearance， immune balance， and immune escape to "transform" the immune cells into immunosuppressive cells in the tumor microenvironment， so as to support immune escape. The five-stage evolution is the summary of tumor pathogenesis by professor LI Jie. He believes that the gradual development of tumors follows the core pathogenesis of "deficiency-cold-toxin-obstruction-collapse"， in which "depression" runs through the whole process， and cancer toxin is the key. Based on immune editing， this paper combined phenotypic characteristics of tumor cells with the core pathogenesis of the five-stage evolution of professor LI to reveal the biological basis of malignant tumor five-stage evolution. The results indicate that the prominent change from deficiency to cold is the reduction of immune surveillance and the prominent change from toxin to obstruction is immune escape. The final stage of collapse is the outcome of immune failure. Depression is the booster of tumor immune editing. Therefore， the method of reinforcing the healthy Qi and removing toxins was proposed to regulate the immune editing and cut off the five-stage evolution of tumors. Supplementing Qi and warming Yang can reinforce the healthy Qi and restore immune surveillance. Removing toxins and dredging can reverse toxins and immune escape. The harmonizing method can maintain the dynamic balance of immune cells/immunosuppressive cells. Resolving depression can truncate tumor immune editing. Those methods can provide a certain reference for the treatment based on microscopic syndrome differentiation in traditional Chinese medicine （TCM）. In future studies， it is necessary to further explore the specific mechanism of the regulation of immune editing with the methods of supplementing Qi and warming Yang， removing toxins and dredging， their combination， and resolving depression， so as to find out specific Chinese medicines and targets and provide more sufficient evidence for the regulation of tumor immune editing by TCM.

OBJECTIVE To identify Ginseng Flos and their confounds by using the high-throughput sequencing technology, and to verify the accuracy of high-throughput sequencing technology in species identification by using ITS2 sequencing technology. METHODS High-throughput sequencing was performed on the amplified products of Ginseng Flos adulterated samples, use cutadapt, PEAR, PRINSEQ, Usearch, RDP classifier, SINTAX software to obtain operational taxonomic unit(OUT) sequences, remove fungi, unclassified and other non-green plant sequences. To avoid false positives, delete OTU sequences with a sequence number <100 or base numbers <200 bp. The ITS2 amplification products of Ginseng Flos, Quinquefolii Flos, and Notoginseng Flos were sequenced. To verify the accuracy of high-throughput sequencing technology for species identification, MEGA 11.0 was used to construct neighbor joining system cluster tree, genetic distance, interspecific information loci and Blast analysis of ITS2 and OTU base sequences of Ginseng Flos, Quinquefolii Flos, and Notoginseng Flos. RESULTS A total of 54 653 valid sequences were obtained by high-throughput sequencing, the serial numbers of Ginseng Flos, Quinquefolii Flos, and Notoginseng Flos were OTU1, OTU2, OTU3, respectively, and the corresponding effective sequences were 31 325, 857 and 442, respectively. By performing a Blast search of ITS2 and OTU base sequences of each species, each species was supported. The genetic distance between Ginseng Flos and Quinquefolii Flos and Notoginseng Flos was 0.010 and 0.033, respectively. Ginseng Flos and Quinquefolii Flos, Notoginseng Flos had 2 and 7 information sites, respectively. The neighbor join system cluster tree showed that the species were clustered independently into one branch, with Ginseng Flos, and Quinquefolii Flos clustered as a large branch and juxtaposed with Notoginseng Flos. Ginseng Flos was the same as Quinquefolii Flos secondary structure, but with Notoginseng Flos there were three different positions but there were A, B and C differences between arm Ⅳ and arm Ⅰ of Notoginseng Flos. CONCLUSION The high-throughput sequencing technology can accurately identify Ginseng Flos, Quinquefolii Flos and Notoginseng Flos, and has a strong ability to identify adulterated samples, which provides a certain idea for the identification of commercial Ginseng Flos.

Mineralized tissue regeneration is an important and challenging part of the field of tissue engineering and regeneration. At present, autograft harvest procedures may cause secondary trauma to patients, while bone scaffold materials lack osteogenic activity, resulting in a limited application. Loaded with osteogenic induction growth factor can improve the osteoinductive performance of bone graft, but the explosive release of growth factor may also cause side effects. In this study, we innovatively used platelet-rich fibrin (PRF)-modified bone scaffolds (Bio-Oss

Objective: To investigate the effect of long-term deep slow-wave sleep deprivation on the gonad axis, sperm abnormality rate, and structure of the testis in male rats and possible mechanisms. Methods: A total of 30 specific pathogen-free male Wistar rats aged 5 weeks were randomly divided into slow-wave sleep deprivation group 1 (SD1 group) , slow-wave sleep and sleep time deprivation group 2 (SD2 group) , and control group, with 10 rats in each group. The flower pot method was used to establish a model of sleep deprivation. In addition to 12-hour sleep deprivation at night, the rats in the SD1 group were given interference once every 24 minutes, and those in the SD2 group were deprived of sleep for 8 minutes every 24 minutes; the rats in the control group were given 12-hour light illumination and then placed in dark environment for 12 hours. All rats were sacrificed by exsanguination from the femoral artery, and the testis, the epididymis, and blood were collected for analysis. Sperm abnormality rate and sperm motility rate were measured, and cauda epididymal sperm counting was performed. ELISA was used to measure the serum levels of testosterone (T) , follicle-stimulating hormone (FSH) , and luteinizing hormone (LH) . Results: Compared with the control group, the SD2 group had a significant increase in organ coefficient of the epididymis (P<0.05) and a significant reduction in sperm motility rate (P<0.05) . There were significant differences between the SD1 group and the SD2 group in the increase in sperm abnormality rate (P<0.05) and the reduction in cauda epididymal sperm count (P<0.05) . The levels of FSH and T tended to increase, and the level of LH tended to decrease. Pathological examination showed degeneration and vacuolization of a small amount of spermatogenic cells in the SD1 group; in the SD2 group, there were significant degeneration, edema, and vacuolization of most spermatogenic cells, some spermatogenic cells were observed in the lumen, and there were no sperms in the lumen. Conclusion Long-term deep slow-wave sleep deprivation impairs the structure of the testis, affects sperm motility rate and sex hormones, and increases the risk of sperm abnormality.
