RESUMO
Objective:To analyze the influencing factors and perform the prediction of olfactory disorders in patients with chronic rhinosinusitis（CRS） based on artificial intelligence. Methods:The data of 75 patients with CRS who underwent nasal endoscopic surgery from October 2021 to February 2023 in the Department of Otorhinolaryngology Head and Neck Surgery, the Third Affiliated Hospital of Sun Yat-sen University were analyzed retrospectively. There were 53 males and 22 females enrolled in the study, with a median age of 42.0 years old. The CRS intelligent microscope interpretation system was used to calculate the proportion of area glands and blood vessels occupy in the pathological sections of each patient, and the absolute value and proportion of eosinophils, lymphocytes, plasma cells and neutrophils. The patients were grouped according to the results of the Sniffin' Sticks smell test, and the clinical baseline data, differences in nasal mucosal histopathological characteristics, laboratory test indicators and sinus CT were compared between the groups. Determine the independent influencing factors of olfactory disorders and receiver operating characteristic curves（ROC） were used to evaluate the performance of the prediction model. Statistical analysis was performed using SPSS 25.0 software. Results:Among the 75 CRS patients, 25 cases（33.3%） had normal olfaction and 50 cases（66.7%） had olfactory disorders. Multivariate Logistic regression analysis showed that tissue eosinophils percentage（OR=1.032, 95%CI 1.002-1.064, P=0.036）, Questionnaire of olfactory disorders-Negative statement（QOD-NS）（OR=1.079, 95%CI 1.004-1.160, P=0.040） and Anterior olfactory cleft score（AOCS）（OR=2.672, 95%CI 1.480-4.827, P=0.001） were independent risk factors for olfactory disorders in CRS patients. Further research found that the area under the ROC curve（AUC） of the combined prediction model established by the tissue eosinophil percentage, QOD-NS and AOCS was 0.836（95%CI 0.748-0.924, P<0.001）, which is better than the above single factor prediction model in predicting olfactory disorders in CRS. Conclusion:Based on pathological artificial intelligence, tissue eosinophil percentage, QOD-NS and AOCS are independent risk factors for olfactory disorders in CRS patients, and the combination of the three factors has a good predictive effect on CRS olfactory disorders.

Health service is an important part of the integrated development of the Yangtze River Delta. Taking the cooperation practice between Shanghai Tenth People′s Hospital and Suzhou Yinshanhu Hospital as an example, this article introduced the multi-agent cooperation mode of the loose medical alliance including the government, urban hospitals and cross provincial grassroots medical institutions. Among them, the local government provided policy, fund guarantee and guidance, the urban hospital exported management ideas, medicine talents and technologies, and the primary hospital conducted dual training by inviting in and going out to achieve double growth. Through the high gap cooperation between tertiary hospital and primary hospital, Yinshanhu hospital had been comprehensively developed. The loose medical alliance with multi subject coordination and cross region could give full play to the advantages of the loose healthcare alliance mode, achieve multi-win, and have reference significance for promoting the regional integration of medical and health services in the Yangtze River Delta.
RESUMO
The effect of H2O2/TAED/NaHCO3 system, namely NaHCO3 as alkaline agent with the (tetra acetyl ethylene diamine (TAED)) TAED-activated peroxide system, bleaching of alkyl polyglycosides solution was studied by spectrophotometry. The results showed that the optimal bleaching conditions about H2O2/TAED/NaHCO3 system bleaching of alkyl polyglycosides solution were as follows: molar ratio of TAED to H2O2 was 0.06, addition of H2O2 was 8.6%, addition of NaHCO3 was 3.2%, bleaching temperature of 50-65 °C, addition of MgO was 0.13%, and bleaching time was 8h. If too much amount of NaHCO3 was added to the system and maintained alkaline pH, the bleaching effect would be greatly reduced. Fixing molar ratio of TAED to H2O2 and increasing the amount of H2O2 were beneficial to improve the whiteness of alkyl polyglycosides, but adding too much amount of H2O2 would reduce the transparency. In the TAED-activated peroxide system, NaHCO3 as alkaline agent and buffer agent, could overcome the disadvantage of producing black precipitates when NaOH as alkaline agent.

Background and purpose:The effective rate of ifrst-line chemotherapy for advanced lung cancer is 30%-40%. The purpose of this study was to evaluate the efifcacy and adverse effects of pemetrexed combined with carboplatin or cisplatin in the treatment of patients with advanced non-squamous non-small cell lung cancer (NSCLC). Methods:One hundrend and twenty-one patients with advanced non-squamous NSCLC were enrolled in this study and all of these patients had been conifrmed with pathology or cytology. Among the 121 cases, 60 cases were male and 61 were female, the median age was 59 years, adnenocarcinoma in 113 patients and large cell carcinoma in 8 patients. Combination regimen: patients received pemetrexed 500 mg/m2 on day 1 and carboplatin 300 mg/m2 or cisplatin 70 mg/m2 on day 1 by intravenous infusion, administrated every 3 weeks for 2 to 6 cycles. All patients who received 2 or more cycles could be evaluated. Disease control rate (DCR) was the primary end point; secondary end points included progression-free survival (PFS), 1-year survival rate and safety.Results:There was 1 case with complete response (CR), 44 cases achieved partial response (PR), 50 had stable disease (SD) and 26 cases had progressive disease (PD) in the overall cases. ORR and DCR were 37.2% (45/121) and 78.5% (95/121), respectively. The median PFS time was 5.2 months and 1-year survival rate was 59.0%. In pemetrexed combined with carboplatin group, the ORR and DCRwere 38.3% (23/60) and 78.3% (47/60), respectively; The median PFS was 5.1 months (95%CI: 3.8-6.4 month) and 1-year survival rate was 55.2%. The patients treated with pemetrexed plus cisplatin, the ORR and DCR were 36.1% (22/61) and 78.7% (48/61), respectively. Median PFS was 6.2 months (95%CI: 4.3-8.1 month) and 1-year survival rate was 62.5%. There were no statistical differences between carboplatin/pemetrexed and cisplatin/pemetrexed for both ORR, DCR, PFS and 1-year survival rate (P>0.05). The major adverse effects were leukopenia, neutropenia, fatigue and gastrointestinal reaction.Conclusion:Pemetrexed plus platinum chemotherapy could be considered as the ifrst-line treatment option for advanced non-squamous NSCLC patients. Pemetrexed combined with carboplatin/ cisplatin regimen has efifcacy with mild toxicity and better tolerability.
RESUMO
BACKGROUND: There is no study addressing transplantation of umbilical cord mesenchymal stem cells for the treatment of spinocerebellar ataxia.OBJECTIVE: To study the clinical effect of human umbilical cord stem cells transplantation in the treatment of autosomal dominant spinocerebellar ataxias. METHODS: Spinocerebellar ataxias patients selected from Stem Transplantation Center of the 455 Hospital of Chinese PLA were treated with umbilical cord mesenchymal stem cells transplantation via intrathecal injection. The number of umbilical cord mesenchymal stem cells was 107 per transplantation, once per week, for 4 weeks.RESULTS AND CONCLUSION: Both the total score of the International Cooperative Ataxia Rating Scale and Activities of Daily Living score were significantly decreased at 1 month after transplantation compared with before treatment (P < 0.05). The nerve function was significantly improved and the total effective rate was up to 16.7%. Experimental findings indicate that, transplantation of umbilical cord mesenchymal stem cells via intrathecal injection is a feasible and effective treatment to ameliorate the clinical efficacy of spinocerebellar ataxias patients and improve their quality of life.
