Objective To investigate the changes of the immunological factors in subcutaneous exudate and blood components of the rats receiving cutaneous scraping method,and to compare the changes of skin histopathological features before and after cutaneous scraping under microscope.Methods SD rats were randomly divided into two groups,cutaneous-scraping group and non-cutaneous-scraping group.And then each group was divided into three subgroups.The observation indexes included the levels of interleukin (IL)-1β,IL-6 and interferon gamma (IFN-γ) in the blood and the skin,routine blood examination,and skin histopathological features.Results In cutaneous-scraping group,the number of white blood cells in the blood and the levels of IL-1 β and IFN-γ in skin tissues were increased (P < 0.05),the hemolysis rate was increased (P < 0.05).However,the levels of IL-1β,IL-6 and IFN-γin the blood showed no obvious changes.Under the microscope,severe skin edema,vascular congestion and dilatation,and infiltration of inflammatory cells were found in the skin after cutaneous scraping.Conclusion The cutaneous scraping method can activate the immune response rapidly,and the immunological components of the subcutaneous exudate after cutaneous scraping are helpful to the disease treatment.

Objective:To evaluate the feasibility of Full-stack Smart Pelvic Floor Ultrasound (FSPFU) software in the acquisition and measurement of the minimal levator hiatus (LH).Methods:Transperineal pelvic floor ultrasonography was performed in 119 women of 6-month postpartum from Nov.2020 to Jan.2021 of Shenzhen Second People′s Hospital. Mid-sagittal plane of pelvic floor was set as the initial plane, and the three-dimensional volume data was acquired. The dataset was stored in the machine. The offline volume data was manually adjusted to obtain the minimal LH images and measured by four physicians (two junior physicians as the D1 group and two senior physicians as the D2 group). For comparison, the results were also obtained using the fully automated method—the FSPFU software by a junior physician (the D3 group). The obtained parameters of minimal LH included area, circumference, anterioposterior diameter, transverse diameter, left and right levator-urethral gap distance. Analysis time was recorded for each group. The contours of minimal LH were outlined by three groups and the overlapping rate was calculated. The quality of the resulted images was evaluated and scored by another two senior physicians(A and B) independently.Results:The D3 group had a significant shorter analysis time compared with the other two groups, and the D1 group took a longer time than the D2 group, regardless of the cystocele severity (D1: 82.97 s, D2: 62.51 s, D3: 2.71 s, all P<0.05). The intergroup agreements and correlations of the minimum LH area were good (all ICC>0.85, rs>0.70, P<0.001) and the outlined contours were largely overlapped (>92%). There was no significant difference in image quality among the three groups(all P>0.05). Conclusions:FSPFU software can automatically obtain and measure the minimum LH in an efficient and accurate way, which can improve the effectiveness of the present pelvic floor examination. FSPFU software can be an useful tool in the diagnosis of pelvic floor dysfunctional diseases.

Screening and evaluating the diseases responding specifically to traditional Chinese medicine (TCM) will help to highlight the advantages of TCM treatment, and the evaluation method should be standardized with consideration to the unique characteristics of the diseases. The incidence of Sjögren's Syndrome (SS) is increasing year by year, while the pathogenesis of this disease remains unclear. Modern therapies for this disease include biological agents and immunosuppressants, which generally have unsatisfactory efficacy. The TCM treatment of SS focuses on the harmony of the physical and mental health. The Rheumatology Branch of the China Association of Chinese Medicine organizes experts in TCM, Western medicine, and evidence-based medicine to form working groups. Delphi method and bibliometric method were used for analysis, and SS was selected as a disease responding specifically to TCM. Furthermore, the evaluation system was established for this disease, and the consensus regarding this disease was reached after seminar discussion. This paper summarized the whole process of the evaluation of the advantages of TCM treatment of SS. First, because TCM atomization is widely used in clinical practice and enriches TCM administration methods, this therapy is included after other non-drug therapies were taken as characteristic therapies. Second, the evaluation indicators of therapeutic effect should be determined with consideration to international acceptance and the current research status. Third, the expression method should be accurate, standardized, and objective, highlight the natural advantages of TCM, and avoid arbitrary extension. This paper provides a reference for clinicians to explore other diseases responding specifically to TCM.

Objective To investigate the impact of anti-reflux modified duodenal exclusion surgery on glucose metabolism in rats with type 2 diabetes mellitus (T2DM), and to elucidate the role of the duodenum in maintaining glucose homeostasis. MethodsForty male Sprague-Dawley rats aged 5 weeks were fed a high-fat diet and induced with T2DM using low-dose streptozotocin. Thirty-six rats that met the T2DM model criteria were randomly divided into three groups: the simple duodenal exclusion surgery group (DE group), the anti-reflux modified duodenal exclusion group (MDE group), and the sham operation group (SO group), with 12 rats in each group. Gastroenterography was performed 4 weeks after surgery, and the body weight, fasting blood glucose levels, and serum glucagon-like peptide-1 (GLP-1) concentrations were measured before surgery and at 1, 2, 4, and 8 weeks post-surgery. Eight weeks post-surgery, the rats were euthanized, and a 1 cm segment of the biliopancreatic loop was collected from each group for pathological sectioning and HE staining to observe the intestinal mucosal villus length under an optical microscope. Results Gastroenterography showed that there was significant reflux of the contrast agent into the duodenal lumen in the DE group, while no reflux was observed in the MDE group. At one week post-surgery, the body weights of rats in all three groups significantly decreased compared to before surgery (P<0.05), and then the body weights of all groups increased over time, with no significant differences between the groups (P>0.05). Compared with the SO group, the fasting blood glucose levels in the MDE and DE groups significantly decreased at all time points post-surgery (P<0.05), while GLP-1 concentrations significantly increased (P<0.05). The fasting blood glucose levels in the MDE group were lower than those in the DE group at all time points post-surgery (P<0.05), but there were no significant differences in serum GLP-1 concentrations between the MDE and DE groups (P>0.05). Regarding intestinal mucosal morphology, the villus lengths of the biliopancreatic loops in the MDE group were significantly shorter than those in the DE and SO groups (P<0.05). Conclusion Anti-reflux modified duodenal exclusion surgery effectively improves glucose metabolism in T2DM rats by preventing the reflux of chyme into the diverted duodenum, thereby enhancing its hypoglycemic effect.
