Objective:To conduct the clinical effect achieved by the combination of axillary flap trimming and scraping through small axillary incisions in treating bromhidrosis.Methods:From June 2021 to December 2022, a study was conducted on patients with bilateral bromhidrosis in the Department of Plastic Surgery, Jining First People’s Hospital. The study used a self-control method, with one side undergoing axillary flap trimming combined with scraping through small axillary incisions (designated as Group A), while the other side underwent direct axillary flap trimming through central axillary incisions (designated as Group B). Randomization was achieved using a number table method for both sides. In Group A, two short incision lines of 0.5-1.0 cm were designed on both sides of the armpit. These incisions separated all layers of the skin, and excised the sweat glands and fat tissue. Additionally, two drainage openings were left in the surgical area to maintain two drainage tubes through the surgical incision. In Group B, the incision lines of 2-3 cm were designed in the central axillary area. After incision and dissection, four drainage tubes were retained in the operation area. The efficacy evaluation consisted of three aspects: the surgical outcome one month post-operation, categorized as cure, effective, or ineffective; the recurrence of bromhidrosis six months post-operation; and the occurrence of surgical complications. SPSS 25.0 software was used for data analysis, and chi-square test was applied for the comparisons between the two groups in terms of response rate, recurrence rate, and complication rate. A statistically significant difference was determined at the P<0.05 level. Results:A study was conducted on 62 patients, aged between 16 and 35 years, with bilateral bromhidrosis, including 38 males and 24 females. In Group A, 55 patients achieved complete cure, while 7 patients experienced significant improvement, resulting in an overall effectiveness rate of 100%. However, 5 cases of recurrence were observed, with a recurrence rate of 8.1%. Additionally, there were 1 case of subflap hematoma, 2 cases of flap erosion, and 1 case of scar hypertrophy, resulting in a complication rate of 6.5%. In Group B, 58 patients achieved complete cure, while 4 patients experienced improvement, resulting in an overall effectiveness rate of 100%. Three cases of recurrence were reported within 6 months, with a recurrence rate of 4.8%. Furthermore, there were 4 cases of subflap hematoma, 4 cases of flap erosion, 2 cases of flap necrosis, and 4 cases of scar hypertrophy, resulting in a complication rate of 22.6%. Statistical analysis showed no significant difference in treatment response rate ( χ2=0.34, P=0.559) or postoperative recurrence rate ( χ2=0.53, P=1.000) between the two groups. However, the complication rate in Group A was significantly lower than that in Group B ( χ2=6.50, P=0.011). Conclusion:The clinical outcome is satisfactory, achieving a high rate of effectiveness by the combination of axillary flap trimming and scraping through small axillary incisions in treating bromhidrosis. And the complications are fewer compared to the direct axillary flap trimming through central axillary incisions.

Objective To investigate the mechanism of action of integrin α4 (ITGA4) in liver fibrosis based on the anti-liver fibrosis effect of sticky sugar amino acid (SSAA) in rats. Methods A rat model of liver fibrosis was induced by intraperitoneal injection of CCl 4 , and then colchicine and low-, middle-, and high-dose SSAA were used for intervention, with blank control group and SSAA group as control. After 12 weeks of experimental intervention, serum and liver samples were collected to measure the serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and HE staining and Sirius Red staining were used to observe the pathological conditions of liver tissue; quantitative real-time PCR was used to measure the transcriptional level of ITGA4, integrin β1 (ITGB1), transforming growth factor-β1 (TGFβ1), alpha-smooth muscle actin (α-SMA), and TIMP2 in liver tissue; Western blot was used to measure the relative protein expression levels of ITGA4, ITGB1, TGFβ1, α-SMA, MMP2, TIMP1, and TIMP2; immunohistochemistry was used to observe the protein expression of TGFβ1 and α-SMA. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t -test was used for comparison between two groups. Results There were significant increases in AST and ALT in the CCl 4 model group, and intervention with colchicine or low-, middle-, and high-dose SSAA reduced the levels of AST and ALT, with a significant difference between the CCl 4 model group and the other groups (all P < 0.05). HE staining and Sirius Red staining showed disordered structure of hepatic lobules and an increase in collagen fibers in the CCl 4 model group, and the structure of hepatic lobules was improved after intervention with colchicine or low-, middle-, and high-dose SSAA. The CCl 4 model group had significantly higher transcriptional levels of ITGA4, TGFβ1, α-SMA, and TIMP2 than the other groups, and there were significant reductions in the transcriptional levels of each factor after intervention with colchicine or SSAA, with a significant difference between the CCl 4 model group and the other groups (all P < 0.05). The CCl 4 model group had significantly higher protein expression levels of ITGA4, TGFβ1, α-SMA, TIMP2, and TIMP1 and a significantly lower protein expression level of MMP2 than the other groups, and intervention with colchicine or SSAA inhibited the expression of ITGA4, TGFβ1, α-SMA, TIMP2, and TIMP1 and promoted the expression of MMP2. Immunohistochemistry showed that the CCl 4 model group had significantly higher expression levels of TGFβ1 and α-SMA than the other groups, which was inhibited by intervention with colchicine or SSAA. The high-dose SSAA group had the most significant effect in reducing aminotransferases, improving lobular structure, and inhibiting the protein expression of liver fibrosis factors. Conclusion The high expression of ITGA4 in the liver is associated with the development of liver fibrosis, which is consistent with the increases in the expression of TGFβ1 and α-SMA. Inhibiting the expression of ITGA4 can provide more therapeutic targets for liver fibrosis and expand the anti-liver fibrosis mechanism of SSAA.

Event-related potentials (ERPs), especially N100, mismatch negative, P300 and N400, play important roles in the evaluation of consciousness and prognoses of patients with prolonged disorders of consciousness (pDOC). The improvement of ERPs experimental paradigm, analysis of brain origin and brain network of ERPs components, and combination of ERPs with other techniques are the research hotspots in pDOC evaluation. This article reviews the recent advance in the above directions as follows, in order to provide reference for subsequent clinical research.

Objective:To establish and optimize the isolation scheme of exosomes from herpes simplex virus type 1 (HSV-1) infected HEp-2 cells.Methods:The supernatant of HSV-1 infected HEp-2 cells were collected and pretreated with differential centrifugation and filtration, then purified by total exosome isolation (TEI) in combination with size-exclusion chromatography (SEC); and enriched the exosome with ultrafiltration. Western blotting, transmission electron microscopy (TEM) and nanoparticle tracking analysis (NTA) were performed to characterize the purified exosomes.Results:The purified exosomes from HEp-2 cells with or without HSV-1 infection showed positive signals of exosome-specific markers (TSG101 and CD9), and the expression of virus protein gB, VP16 and ICP5 were detected in exosomes derived from HSV-1 infected cells. The purified exosomes from HEp-2 cells with or without HSV-1 infection showed a typical round-shaped morphology under TEM, with a mean diameter of 50~150 nm; meanwhile, no typical HSV-1 virus particles were detectable. The peak diameter of purified exosomes was 112.2 nm, furthermore, the peak concentration of exosomes from HEp-2 control cells was 3.4×10 9 particles/ml, while the peak concentration of exosomes from HSV-1 infected cells was 4.1×10 9 particles/ml. Conclusions:We accomplished an efficient and optimized approach for the isolation and purification of exosomes from HSV-1 infected cells.

Objective:To recognize the development pattern of COVID-19 epidemic, and to predict the development trend of the epidemic in three categories: the country, Hubei province, and areas outside Hubei province.Methods:The BloComp model was used to fit existing data. With the estimated parameters, we simulated future epidemic development.Results:The pattern of virus transfer among different populations in Hubei province was significantly different from that outside Hubei province. It is predicted by the BloComp model that the time when the number of confirmed cases fell to zero in Hubei province and areas outside Hubei will be May 2020 and April 2020, respectively.Conclusions:The epidemic situation will end at the end of May 2020. Adequate medical resources investment and more comprehensive and accurate investigation of suspected people play important roles in controlling the epidemic situation.
