Objective To explore the effect of community pharmacy outpatient service on patients with type 2 diabetes mellitus. Methods A non-randomized controlled study was conducted, and type 2 diabetes patients managed in the community were divided into an intervention group of 112 cases and a control group of 110 cases. The control group received routine medication guidance during general practice outpatient visits, while the intervention group received comprehensive pharmacy outpatient service intervention based on routine medication guidance in general practice. Follow-up visits were conducted every 3 months. Repeated measurement analysis of variance and multivariate linear regression analysis were used to evaluate the intervention effect of the pharmacy outpatient service. Results Fasting blood glucose and glycosylated hemoglobin levels in the intervention group showed a decreasing trend with the increase of intervention time compared to pre-intervention time （P<0.01）, with increased duration of weekly exercise, decreased staple food intake, increased vegetable intake, and increased medication adherence score （P<0.01）. After adjusting for confounding factors through multivariate linear regression model, pharmacy outpatient intervention was found to be an independent protective factor for fasting blood glucose level （β=−0.891, P<0.01） and glycosylated hemoglobin level （β=−0.760, P<0.01） in the study subjects. Conclusion The community pharmacy outpatient service could enhance the self-management ability of patients with type 2 diabetes mellitus, and effectively improve patients’ fasting blood glucose and glycosylated hemoglobin.

Objective To investigate the effects and underlying mechanisms of a spray prepared from exosomes derived from M2 macrophages induced by interleukin-4 （IL-4） and tantalum particles （Ta） on the healing of pressure ulcers. Methods Bone marrow-derived macrophages were polarized into M2 macrophages using IL-4 or Ta, and exosomes （Exo-IL-4/Exo-Ta） were extracted. The regulatory effects of Exo-IL-4/Exo-Ta on M1 macrophage phenotypes and fibroblast matrix secretion were evaluated in vitro. Proteomic analysis was conducted to explore the biological processes and regulatory networks associated with Exo-Ta. A rat pressure ulcer model was used to assess the effects of Exo-IL-4/Exo-Ta spray on wound healing rate, inflammatory cell infiltration, and collagen deposition. Results In vitro, Exo-IL-4/Exo-Ta induced the polarization of M1 macrophages to M2 macrophages, reduced the secretion of pro-inflammatory factors, and promoted the expression of anti-inflammatory substances. Additionally, Exo-IL-4/Exo-Ta enhanced the production of collagen and fibronectin in fibroblasts. Proteomic analysis revealed that Exo-Ta primarily participated in biological processes such as energy metabolism and macromolecule biosynthesis. In vivo, Exo-IL-4/Exo-Ta spray accelerated wound healing, reduced inflammatory infiltration, and improved tissue remodeling in the rat pressure ulcer model. Conclusion Exosome sprays derived from M2 macrophages could accelerate pressure ulcer healing by modulating inflammation and promoting tissue regeneration, which demonstrated excellent clinical application potential.

Objective To investigate the predict value of imaging parameters in computed tomography perfusion(CTP)combined with computed tomography angiography(CTA)examination and serum biomarkers for recurrent stroke events at three-month and one-year follow-ups.Methods A total of 136 patients with cerebral infarction diagnosed for the first time were included in the retrospective study.These patients received CTA+CTP one-stop examination and serum biomarkers testing,followed by three-month and one-year follow-ups for the occurrence of recurrent stroke events.Recurrent stroke events were defined as ischemic stroke,retinal infarction,intracerebral hemorrhage,subarachnoid hemorrhage,and death.Results The recurrent stroke events rate was 23.5%(32 cases)and 36.8%(50 cases)at three-month and one-year follow-ups,respectively.Ischemic penumbra(IP)volume[odds ratio(OR)=1.010,P=0.029]and modified Rankin scale(mRS)score at discharge(OR=1.388,P=0.008)were independent predictors for recurrent stroke events at the three-month follow-up,so were lipoprotein(a)[Lp(a)](OR=1.002,P=0.044),vascular stenosis severity(OR=1.489,P=0.029),and mRS score at discharge(OR=1.282,P=0.038)at the one-year follow-up.Conclusion Among patients with stroke diagnosed for the first time,IP volume,Lp(a),vascular stenosis severity and mRS score at discharge are the most powerful predictors of recurrent stroke events at three-month and one-year follow-ups.

Three children with Skene duct cyst were presented in this article. By reviewing literature, in pediatric population, Skene duct cycts mostly occur in newborns and conservative therapy is the first choice in this group.In contrast, it is extremely rare between the ages of 1 and 12, and surgical excised is the preferred therapy because of having a similar pathogenesis to adults.

ObjectiveTo investigate current status of hospital infection management in psychiatric hospitals in the Ningxia Hui Autonomous Region， so as to provide references for improving the level of hospital infection management of psychiatric hospitals. MethodsIn December 2020， on-site supervision was conducted on hospital infection management in all 9 psychiatric hospitals in the Ningxia Hui Autonomous Region， meantime， the self-compiled questionnaire on hospital infection management status was used for investigation. ResultsAmong the selected hospitals， nine （100.00%） psychiatric hospitals had the main hospital leaders in charge of hospital infection management， five （55.56%） hospitals had established a hospital infection management committee， six （66.67%） hospitals had established an independent hospital infection management department， and one （11.11%） hospital had developed all 13 systems mentioned in the questionnaire related to hospital infection management and job responsibilities. In terms of hospital infection management staff， there were 23 staff members in the nine psychiatric hospitals， including 3 in the specialty （13.04%） and 20 in the part-time setting （86.96%）. The score of the implementation of the basic system of hospital infection management in nine hospitals was （3.28±2.22）. ConclusionThe system specification related to hospital infection management in the Ningxia Hui Autonomous Region psychiatric hospitals needs to be improved and further strengthened， the professionalism of hospital infection management personnel needs to be improved.

Objective To investigate the biochemical and routine blood parameters in hepatocellular carcinoma (HCC) patients with portal vein blood thrombus (PVBT) or portal vein tumor thrombosis (PVTT), as well as the expression level and clinical significance of inflammatory indices in patients with different types of PVBT. Methods A total of 51 HCC patients with PVBT and 37 HCC patients with PVTT who were diagnosed and treated in The Second Affiliated Hospital of Zhengzhou University from January 2016 to December 2020 were enrolled as PVBT group and PVTT group, respectively, and 50 HCC patients without portal vein thrombosis who were hospitalized during the same period of time were enrolled as control group. General clinical data and laboratory test results were collected from the three groups. The chi-square test or the Kruskal-Wallis rank sum test was used for comparison of categorical data between groups; a one-way analysis of variance was used for comparison of normally distributed continuous data between groups, and the Kruskal-Wallis rank sum test was used for comparison of non-normally distributed continuous data between groups. The receiver operating characteristic (ROC) curve was plotted to investigate the expression levels of albumin (Alb), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and interleukin-6 (IL-6) in the PVBT group and the PVTT group, and the area under the ROC curve (AUC) was calculated to analyze their value in predicting different types of thrombosis. Results There were no significant differences in general data and conventional biochemical parameters between the three groups (all P > 0.05), while there were significant differences in the inflammatory indices Alb, CRP, ESR, and IL-6 between the three groups ( H =10.207, 24.465, 8.917, and 37.584, P =0.006, P < 0.001, P =0.012, and P < 0.001), and further analysis between two groups showed that the PVTT group had a significantly lower level of Alb and significantly higher levels of CRP, ESR, and IL-6 than the PVBT group and the control group, and the PVBT group had significantly higher levels of CRP and IL-6 than the control group (all P < 0.05). The ROC curve analysis showed that Alb, CRP, ESR, and IL-6 had an AUC of 0.659, 0.826, 0.679, and 0.873, respectively, in the PVTT group, as well as an AUC of 0.508, 0.635, 0.503, and 0.701, respectively, in the PVBT group. Conclusion HCC patients with PVTT tend to have high expression levels of the inflammatory indices IL-6, CRP, and ESR and a low expression level of Alb, and their predictive value decreases successively, while HCC patients with PVBT tend to have relatively low expression levels IL-6, CRP, and ESR and a relatively high expression level of Alb. IL-6 and CRP have a certain value in predicting PVBT, while ESR and ALB have little predictive value.

Objective To investigate the expression of mitochondrial autophagy-associated protein PINK1 and Parkin in parotid pleomorphic adenoma (PA) and carcinoma ex pleomorphic adenoma(CA-EX-PA). Methods The expression of PINK1 and Parkin were detected by immunohistochemistry in 24 cases of normal parotid gland tissues, 32 cases of PA tissues and 42 cases of CA-EX-PA tissues. The correlations of PINK1 and Parkin expression with the clinicopathologic characteristics of CA-EX-PA patients were analyzed. Results The positive rates of PINK1 in normal parotid gland, PA and CA-EX-PA tissues were 100%, 91% and 67% respectively; and those of Parkin were 100%, 88% and 52% respectively. The expression rates of PINK1 and Parkin in PA and CA-EX-PA tissues were significantly lower than those in normal tissues (P < 0.05). The expression of PINK1 and Parkin protein were positively correlated in CA-EX-PA tissues (r=0.877, P < 0.01). In CA-EX-PA tissues, the expression of PINK1 and Parkin were associated with tumor invasion, lymph node metastasis and TNM stage (P < 0.05). Conclusion The expression of PINK1 and Parkin are decreased in PA and CA-EX-PA tissues. The decrease of mitochondrial autophagy activity might play important roles in the development, invasion and metastasis of parotid gland tumors.

Objective:To analyze the survival benefits and treatment related toxic effects of simultaneous integrated boost intensity-modulated radiotherapy (SIB-RT) for non-operative esophageal squamous cell carcinoma patients.Methods:The data of 2 132 ESCC patients who were not suitable for surgery or rejected operation, and underwent radical radiotherapy from 2002 to 2016 in 10 hospitals of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG) were analyzed. Among them, 518 (24.3%) cases underwent SIB (SIB group) and 1 614 (75.7%) cases did not receive SIB (No-SIB group). The two groups were matched with 1∶2 according to propensity score matching (PSM) method (caliper value=0.02). After PSM, 515 patients in SIB group and 977 patients in No-SIB group were enrolled. Prognosis and treatment related adverse effects of these two groups were compared and the independent prognostic factor were analyzed.Results:The median follow-up time was 61.7 months. Prior to PSM, the 1-, 3-, and 5-years overall survival (OS) rates of SIB group were 72.2%, 42.8%, 35.5%, while of No-SIB group were 74.3%, 41.4%, 31.9%, respectively ( P=0.549). After PSM, the 1-, 3-, and 5-years OS rates of the two groups were 72.5%, 43.4%, 36.4% and 75.3%, 41.7%, 31.6%, respectively ( P=0.690). The univariate survival analysis of samples after PSM showed that the lesion location, length, T stage, N stage, TNM stage, simultaneous chemoradiotherapy, gross tumor volume (GTV) and underwent SIB-RT or not were significantly associated with the prognosis of advanced esophageal carcinoma patients who underwent radical radiotherapy ( P<0.05). Cox model multivariate regression analysis showed lesion location, TNM stage, GTV and simultaneous chemoradiotherapy were independent prognostic factors of advanced esophageal carcinoma patients who underwent radical radiotherapy ( P<0.05). Stratified analysis showed that, in the patients whose GTV volume≤50 cm 3, the median survival time of SIB and No-SIB group was 34.7 and 30.3 months ( P=0.155), respectively. In the patients whose GTV volume>50 cm 3, the median survival time of SIB and No-SIB group was 16.1 and 20.1 months ( P=0.218). The incidence of radiation esophagitis and radiation pneumonitis above Grade 3 in SIB group were 4.3% and 2.5%, significantly lower than 13.1% and 11% of No-SIB group ( P<0.001). Conclusions:The survival benefit of SIB-RT in patients with locally advanced esophageal carcinoma is not inferior to non-SIB-RT, but without more adverse reactions, and shortens the treatment time. SIB-RT can be used as one option of the radical radiotherapy for locally advanced esophageal cancer.

Objective:To evaluate the effect of definitive radiotherapy with different doses on overall survival (OS) and identify the prognostic factors of patients with non-metastatic esophageal squamous cell carcinoma (ESCC).Methods:Clinical data of 2 344 ESCC patients treated with definitive radiotherapy (RT) alone or chemoradiotherapy from 2002 to 2016 in 10 hospitals were collected and analyzed retrospectively. After the propensity score matching (PSM)(1 to 2 ratio), all patients were divided into the low-dose group (equivalent dose in 2 Gy fractions, EQD 2Gy<60 Gy; n=303) and high-dose group (EQD 2Gy≥60 Gy; n=606) based on the dose of radiation. Survival analysis was conducted by Kaplan- Meier method. Multivariate prognostic analysis was performed by Cox′s regression model. Results:The median follow-up time was 59.6 months. After the PSM, the 1-, 3- and 5-year overall survival (OS) rate was 66.5%, 34.7%, 27.2% in the low-dose group, 72.9%, 41.7% and 34.7% in the high-dose group, respectively ( P=0.018). The 1-, 3-and 5-year progression-free survival rate was 52.2%, 27.2%, 23.1% in the low-dose group, 58.3%, 38.1% and 33.9% in the high-dose group, respectively ( P=0.001). The outcomes of univariate analysis indicated that cervical/upper esophagus location, early (stage Ⅱ) AJCC clinical stage, node negative status, tumor length ≤5 cm, receiving intensity-modulated radiation therapy (IMRT), receiving concurrent chemotherapy and EQD 2Gy≥60 Gy were closely associated with better OS (all P<0.05). Multivariable analysis demonstrated that tumor location, regional lymph node metastasis, concurrent chemotherapy and EQD 2Gy were the independent prognostic factors for OS (all P<0.05). Conclusion:Three-dimensional conformal or IMRT with EQD 2Gy≥60 Gy yields favorable survival outcomes for patients with locally advanced ESCC.
