Objective:To retrospectively analyze the independent risk factors of complicated appendicitis(CA)in children under five years old and establish a clinical prediction model, and to evaluate the clinical application of this model.Methods:A retrospective analysis was performed on children under five years old who underwent appendectomy at Children′s Hospital of Shanghai Jiao Tong University School of Medicine from January 2018 to December 2021.The children were divided into CA group and uncomplicated appendicitis group according to whether there was sign of perforation or gangrene in appendiceal tissue after operation.The differences in clinical features and preoperative laboratory test results between two groups were compared.The independent risk factors of CA were identified and a clinical prediction model was established.The clinical prediction model was verified by receiver operating characteristic curve.Results:A total of 140 children were enrolled in this study, including 84 cases in the CA group and 56 cases in uncomplicated appendicitis group.Univariate and binary Logistic regression analysis showed that the duration of symptoms>23.5 h( OR=6.650, 95% CI 2.469-17.912, P<0.05), abdominal muscle tension( OR=3.082, 95% CI 1.190-7.979, P<0.05) and C-reactive protein>41 mg/L ( OR=3.287, 95% CI 1.274-8.480, P<0.05) were independent risk factors for CA( P<0.05). The clinical prediction model of CA was constructed by the above mentioned three independent risk factors.The area under the receiver operating characteristic curve of the clinical prediction model was 0.881(95% CI 0.825-0.936), the sensitivity was 77.4%, the specificity was 87.5%, the positive predictive value was 91.3% and the negative predictive value was 70.0%. Conclusion:Acute appendicitis in children under five years old is more likely to progress to CA if the duration of symptoms>23.5 h, the level of C-reactive protein is increased, and the abdominal muscle tension is accompanied.The clinical prediction model of CA constructed by common clinical information in pediatric clinics has good prediction efficiency, which provides a simple and feasible reference method for clinicians to distinguish CA from uncomplicated appendicitis.

Objective:To establish a decision tree model of pediatric complicated appendicitis (CA) based on Pediatric Appendicitis Score (PAS) combined with inflammatory indicators, and to evaluate its clinical application efficacy in pediatrics.Methods:The clinical data of 544 children diagnosed with appendicitis in Children′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2018 to December 2021 was retrospectively analyzed. According to postoperative pathology, the children were divided into uncomplicated appendicitis group and CA group. The independent risk factors of CA were screened by univariate and multivariate logistic regression analysis, and these parameters were included to establish the decision tree model. The accuracy of the decision tree model was verified by receiver operating characteristic (ROC) curve.Results:Binary logistic regression analysis indicated that the PAS, C-reactive protein (CRP) and neutrophil to lymphocyte ratio (NLR) were identified as independent risk factors for complicated appendicitis in children (all P<0.05). PAS, CRP and NLR were included as covariables to construct the decision tree model and binary logistic regression model for predicting CA. The decision tree demonstrated an overall accuracy of 79.2% with a sensitivity of 86.7% and specificity of 71.9%, and achieved an area under curve (AUC) of 0.821(95% CI: 0.786-0.857). The binary logistic regression model had a sensitivity of 79.6% and specificity of 69.1%, with an overall accuracy of 75.1% and achieved an AUC of 0.808(95% CI: 0.770-0.845). Conclusions:The decision tree model based on PAS score combined with CRP, NLR is a simple, intuitive and effective tool , which can provide pediatric emergency physicians a reliable basis for diagnosis of pediatric CA.

Objective: : Angiolipomas are usually found in the subcutaneous tissue of the trunk and limbs. Spinal angiolipomas (SALs) are uncommon and have rarely been reported. We report a series of nine SALs patients who received surgical treatment in our department. To summarize the clinical characteristics of SALs, propose our surgical strategies, and evaluate the effects of the operation. Methods: : This was a retrospective review of nine SALs patients who received surgical treatment from August 2015 to March 2020. Total or subtotal resection was determined by the axial localization (dorsal or ventral) and the extent of intervertebral foramen involvement. The outcomes were assessed based on the modified Japanese Orthopaedic Association (mJOA) scoring system utilized before surgery and at various follow-up points. Results: : Among the nine patients, the mean mJOA score before surgery was 6.6±2.3, compared with 10.1±1.1 at the last follow-up time point (33.4±11.8 months). All patients achieved good outcomes, even in cases of subtotal resection. Conclusion : Early surgical resection of SALs is recommended, and the specific procedures should be determined by the axial localization (dorsal or ventral) and the extent of intervertebral foramen involvement. Most of the patients had a good prognosis, even in cases of subtotal resection.

Background: Esophageal mucosal injury induced by gastroesophageal reflux is a key link to the development of Barrett's esophagus-associated adenocarcinoma. However, the molecular mechanism is still not elucidated. Aims: To investigate the role of differentially expressed genes (DEGs) after stimulating esophageal cells with acid and bile acid in the development of esophageal adenocarcinoma (EAC). Methods: The DEGs were obtained through bioinformatics methods after stimulating esophageal cells with low pH and deoxycholic acid, and GO, KEGG enrichment analysis were performed. Protein-protein interaction (PPI) network was performed to screen the hub genes, and their relationships with prognosis and tumor stage of EAC patients were analyzed. The role of co-expressed genes of GADD45B in EAC was also analyzed. Results: Thirty-one overlapping DEGs were obtained after stimulating esophageal cells with low pH and deoxycholic acid, which mainly enriched in the cytokine-cytokine receptor interaction, transcription factors activity, and regulation of cell proliferation and apoptotic process. High expression of GADD45B was correlated with the survival prognosis and tumor stage of EAC patients. GADD45B and its co-expressed genes were involved in the production of tumor necrosis factor. Conclusions: The high expression of GADD45B induced by acid and bile acid is correlated with the prognosis and tumor stage of EAC patients, and is a potential diagnosis and treatment target for Barrett's esophagus-associated adenocarcinoma.

OBJECTIVE： To provide reference for strengthening the construction of retail pharmacy pharmacists and ensure safe and rational use of drugs.  METHODS： A simple random sampling method was used to determine 18 cities （counties） in Guizhou province as survey sites to visits all retail drugstores one by one. According to the Pharmacist Pharmaceutical Care Competency Evaluation Standard（Trail） issued by the Chinese Pharmacists Association， questionnaire survey and face-to-face interviews were conducted with licensed pharmacists in Guizhou province’s retail pharmacies， and multiple linear regressions were conducted on the factors affecting the pharmacy’s pharmaceutical care competency.  RESULTS： A total of 943 retail pharmacies in Guizhou province were visited， and 270 licensed pharmacists were investigated. The total self-assessment score of pharmaceutical care competence was （79.62±11.23）， with 11.5％ of undergraduate education and above， and 53.0％ of pharmacy related majors. Among self-assessment score of pharmaceutical care competency， score of basic knowledge item such as foreign language knowledge， statistical knowledge and computer knowledge was the lowest， followed by clinical thinking ability and drug treatment evaluation ability. The results of multiple linear regression showed that age had significant influence on the scores of basic skills and professional knowledge. The influence of academic qualifications on personal accomplishment， basic knowledge， basic skills， professional knowledge and professional skills score was statistically significant； the influence of professional and technical positions on total score， personal accomplishment， basic skills and professional skills score was statistically significant （P＜0.05）. CONCLUSIONS： The overall educational level of licensed pharmacists in Guizhou retail pharmacies is low and their professional level is limited. It is suggested that the supervision of licensed pharmacists should be strengthened and the access conditions of licensed pharmacists should be improved； the education and training of professional competency of licensed pharmacists in pharmaceutical care should be strengthened， the functional orientation of licensed pharmacists in retail pharmacies should be clarified， and public safety and rational drug use should be effectively guaranteed.

Objective: To study the immune regulation function of high expressing interleukin-10 (IL-10) in B cells on CD4⁺T-cells in periodontitis mouse model. Methods: Twenty-four 7-weeks-old female C57BL/6 mice were randomly and equally assigned into 4 groups: the healthy control group (HC group, n=6), the ligation combined Porphyromonasgingivalis (Pg) infection group (P group, n=6), the ligation combined Pg infection with non-stimulated B cell transfer group (P+NSB group, n=6) and the ligation combined Pg infection with stimulated B cell transfer group (P+SB group, n=6). Ligation combined Pg infection of the maxillary second molar was used to induce periodontitis of mice. The exogenous non-stimulated B cells or stimulated B cells were injected into the palate gingivalat the 5th day after ligation, and all mice were sacrificed at the 14th day. HE stain was used to detect the histological of periodontal tissues, toluidine blue stain was used to analysis the alveolar bone loss, immunofluorescence stain was used to detect the expression of CD4⁺T-cell and IL-10, immunohistochemical was used to detect the expression of receptor activator of NF-κB ligand (RANKL) and IL-1β. Results: Results of HE staining showed that more hyperplasia of gingival epithelium and the alveolar bone resorption in P group, P+NSB group and P+SB group compared with HC group. Results of toluidine blue staining showed that the alveolar bone losses in P group [(0.668±0.041) mm²], P+NSB group [(0.750±0.039) mm²] and P+SB group [(0.517±0.038) mm²] were significantly increased compared with that in HC group [(0.336±0.029) mm²](F=146.051, P<0.01), and the alveolar bone resorption was significantly increased in P+NSB group compared with that in P group (F=146.051, P<0.01). However, compared with P+NSB group and P group, the alveolar bone loss in P+SB groupwas significantly decreased (F=146.051, P<0.01). Results of immunofluorescence staining showed that CD4⁺T-cells expressed in P group [(287.5±37.9) cell/mm²], P+NSB group [(314.6±53.3) cell/mm²] and P+SB group [(185.4±42.9) cell/mm²] were higher than that in HC group [(12.5±13.7) cell/mm²)(F=71.284, P<0.01). Compared with P group and P+NSB group, CD4⁺T-cells expression in group P+SB was decreased (F=71.284, P<0.01). IL-10 levels were increased in P group [(111.7±20.4) cell/mm²], P+NSB group [(126.7±15.1) cell/mm²] and P+SB group [(191.0±22.6) cell/mm²] compared with that in HC group [(22.7±4.3) cell/mm²] (F=98.516, P<0.01), and the IL-10 expressed in P+SB group was significantly higher than those in P+NSB group and P group. Results of immunohistochemical tests showed that RANKL expressions in gingival tissues among P group [(674.0±71.5) cell/mm²], P+NSB group [(831.0±97.5) cell/mm²] and P+SB group [(420.1±40.8) cell/mm²] were significantly higher than that in HC group [(69.3±29.1) cell/mm²] (F=154.886, P<0.01). However, it dramatically decreased in P+SB group compared with those in P group and P+NSB group.The IL-1βexpression in P group [(447.8±40.8) cell/mm²], P+NSB group [(512.5±38.2) cell/mm²] and P+SB group [(281.6±32.4) cell/mm²] were significantly higher than that in HC group [(50.8±20.9) cell/mm²], and it also higher in P+NSB group compared with in P group. However, it decreased in P+SB group compared with those in P group and P+NSB group (F=221.185, P<0.01). Conclusions High expression IL-10 in B cell smight inhibit alveolar bone loss, RANKL and IL-1β expressions and CD4⁺T-cell infiltration through IL-10.
