Objective:To investigate the rates of low disease activity and clinical remission in patients with systemic lupus erythematosus(SLE)in a real-world setting,and to analyze the related factors of low disease activity and clinical remission.Methods:One thousand patients with SLE were enrolled from 11 teaching hospitals.Demographic,clinical and laboratory data,as well as treatment regimes were collec-ted by self-completed questionnaire.The rates of low disease activity and remission were calculated based on the lupus low disease activity state(LLDAS)and definitions of remission in SLE(DORIS).Charac-teristics of patients with LLDAS and DORIS were analyzed.Multivariate Logistic regression analysis was used to evaluate the related factors of LLDAS and DORIS remission.Results:20.7％of patients met the criteria of LLDAS,while 10.4％of patients achieved remission defined by DORIS.Patients who met LLDAS or DORIS remission had significantly higher proportion of patients with high income and longer disease duration,compared with non-remission group.Moreover,the rates of anemia,creatinine eleva-tion,increased erythrocyte sedimentation rate(ESR)and hypoalbuminemia was significantly lower in the LLDAS or DORIS group than in the non-remission group.Patients who received hydroxychloroquine for more than 12 months or immunosuppressant therapy for no less than 6 months earned higher rates of LLDAS and DORIS remission.The results of Logistic regression analysis showed that increased ESR,positive anti-dsDNA antibodies,low level of complement(C3 and C4),proteinuria,low household in-come were negatively related with LLDAS and DORIS remission.However,hydroxychloroquine usage for longer than 12 months were positively related with LLDAS and DORIS remission.Conclusion:LLDAS and DORIS remission of SLE patients remain to be improved.Treatment-to-target strategy and standar-dized application of hydroxychloroquine and immunosuppressants in SLE are recommended.

Objective To investigate the role of lipopolysaccharide(LPS)in regulating the inflammatory response of neutrophil through the leucine-rich α-2 glycoprotein 1(LRG1)/Rho-associated protein kinase(ROCK1)signaling.Methods HL-60 cells were treated with 1 μmol/L all-trans retinoic acid(ATRA)and 12.5 μL/mL dimethyl sulfoxide(DMSO)for 72 h and 96 h,and the morphological changes were observed by Wright-Giemsa staining.The expression of CD11b was detected by flow cytometry.LPS induced the activation of dHL-60 and human peripheral blood neutrophils.The transcription and secretion levels of LRG1,ROCK1 and inflammatory cytokines were detected by qPCR and ELISA,respectively.The expression levels of LRG1 and ROCK1 after the activation of dHL-60 were detected by Western blotting.Furthermore,dHL-60 was treated with the recombinant protein LRG1 and ROCK1 inhibitor Y-27632;the transcription levels of inflammatory cytokines were detected by qPCR.Results Neutrophils were activated by LPS.The expression levels of LRG1 and ROCK1 were significantly increased,and the transcription levels of inflammatory cytokines were significantly increased.The recombinant protein LRG1 activated dHL-60 in vitro,and the transcription levels of ROCK1 and inflammatory cytokines were significantly increased.Using the ROCK1 inhibitor Y-27632,the production levels of inflammatory cytokines were significantly reduced.Conclusion LPS can regulate the production levels of neutrophil inflammatory cytokines through activating the LRG1/ROCK1 signaling,thus exacerbating the inflammatory response.

Objective:To explore the mechanism by which Pien Tze Huang improves liver Kupffer cell damage induced by lipopolysaccharide (LPS) by regulating the expression of miR-155.Methods:LPS induced liver Kupffer cells to establish a cell injury model to simulate septic liver injury. RT-qPCR was used to detect the expression of miR-155 in damaged cells, and RT-qPCR, Western Blot, ELISA and flow cytometry were used to evaluate the inflammatory response and apoptosis of damaged cells. Then we treated LPS-induced Kupffer cells with Pien Tze Huang at different concentrations (0 mg/L, 5 mg/L, 10 mg/L and 15 mg/L), and detected the expression of miR-155 in the cells, the inflammatory response of the cells and Apoptosis rate. MiR-155 was silenced in the cell injury model, and RT-qPCR, Western Blot, ELISA and flow cytometry were used to evaluate the effect of miR-155 on inflammatory response and apoptosis of model cells. Overexpression of miR-155 in damaged cells treated with Pien Tze Huang was used to detect changes in cellular inflammatory response and apoptosis. Data are expressed in the form of mean ± standard deviation, and each group of data is analyzed using t test or one-way analysis of variance.Results:In the LPS-induced liver Kupffer cell injury model, the expression of miR-155 was significantly increased ( P<0.05), the expression levels of pro-inflammatory factors IL-6 and TNF-α were significantly increased, and the anti-inflammatory factor IL-10 was significantly increased. was inhibited ( P<0.05), and the cell apoptosis rate was significantly increased ( P<0.05). After Pien Tze Huang treatment, the expression of miR-155 in damaged liver cells was inhibited ( P<0.05), the levels of cellular inflammatory factors IL-6 and TNF-α were inhibited, and the expression of anti-inflammatory factor IL-10 was promoted ( P<0.05). Inhibit cell apoptosis ( P<0.05). Silencing miR-155 reduced the inflammatory response and apoptosis rate of cells ( P<0.05). Overexpression of miR-155 can reverse the effect of Pien Tze Huang on liver cell injury ( P<0.05). Conclusions:In the model of LPS-induced liver Kupffer cell injury, Pien Tze Huang can inhibite the inflammatory response and apoptosis of cells by inhibiting the expression of miR-155.

Objective:To establish a prediction method of diopter based on sequence of ocular biological parameters.Methods:A stratified random cluster sampling method was used to extract the dataset. The dataset consisted of data collected from January 2022 to January 2023 by the Eye & ENT Hospital, Fudan University, from children aged 5 to 13 years in 2 key schools and 2 general schools of Yangpu District, Shanghai. Children’s ocular biological parameters, including sex, age, diopter, axial length, corneal curvature, and anterior chamber depth were collected. The slope of the optimally fitted straight line was calculated using the least squares method. The least square-back propagation (BP) neural network model was established by combining baseline data and the pre-processed rate of the change of ocular biological parameters. The dataset was divided into the training set and the validation set according to the ratio of 8:2 for five-fold cross-validation. The model performance was evaluated by using the mean absolute error (MAE), mean squared error (MSE), root mean square error (RMSE), correlation coefficient R, and coefficient of determination R2. Results:The optimal performances of R2, R, RMSE, MAE, and MSE of the least square-BP neural network model were 0.96, 0.981 9, 0.214 2, 0.139 9 D, 0.045 9, respectively. The regression equation between the predicted value and the true value of the diopter was y=0.97 x+ 0.014 8, R2=0.97, with good correlation. In the internal verification, MAE values of the diopter at three, six, nine, and twelve months of follow-up were 0.110 1, 0.136 0, 0.153 7, and 0.184 8 D, respectively, which achieved clinically acceptable performance (less than 0.25 D). In the external validation, the errors were less than 0.25 D at all ages. Conclusions:A prediction method of diopter based on sequence of ocular biological parameters was successfully developed.

Cervical cancer is a malignant tumor of the female reproductive system, which is closely related to persistent infection with high-risk human papillomavirus (HPV). Locally advanced cervical cancer (LACC) refers to cervical cancer of stage IB3 to IVA [International Federation of Gynecology and Obstetrics (FIGO) 2018 staging], characterized by tumor diameter greater than 4 cm or invasion of adjacent tissues. The standard treatment for LACC is concurrent chemoradiotherapy, with cisplatin as the preferred chemotherapeutic agent. However, there is still a clinical need for further improvement of the overall prognosis of LACC, and exploring effective adjuvant treatment strategies after concurrent chemoradiotherapy to increase the cure rate and quality of life of LACC patients is an important topic in clinical practice. This article reviews the types, indications, effects and existing problems of adjuvant treatment after concurrent chemoradiotherapy for LACC.

Malignant tumors are a major health problem in current society. With the improvement of people's living standards and the changes in diet structure， the development trend of gastrointestinal tumors in China is gradually similar to that in developed countries. The incidence and mortality of colorectal cancer （CRC） remain high in China. Although targeted therapy and immunotherapy have greatly improved the prognosis of patients in recent years， chemotherapy is still the main means in clinical practice. However， the adverse reactions of chemotherapy often seriously affect the quality of life of patients， and even lead to treatment interruption， thereby affecting the efficacy. Oral Chinese medicine shows unique advantages in enhancing efficiency and reducing toxicity in CRC patients during chemotherapy， but its poor drug experience not only makes it difficult for patients to take it consistently but also affects the popularization of Chinese medicine at this stage. Medicinal and edible herbs （MEHs） are an important part of Chinese medicine and they are mild， delicious， convenient， affordable， nutritious， and safe. Therefore， they may be more suitable for patients with CRC chemotherapy to adhere to treatment. However， their efficacy is often criticized by clinical practitioners. They are only used in the food and health products industry， and their role as Chinese medicines has not been fully utilized. This paper summarized the common traditional Chinese medicine （TCM） syndromes and treatment methods during CRC chemotherapy， sorted out the nature， flavor， meridian tropism， and efficacy of MEHs， and reviewed the modern pharmacological research results of MEHs by the method of literature statistics. This study finds that the nature， flavor， meridian tropism， and efficacy of MEHs are in good agreement with the common TCM syndromes and treatment methods during CRC chemotherapy. Moreover， many MEHs have the effects of resisting CRC and alleviating the adverse reactions of chemotherapy. Furthermore， the effectiveness and superior efficacy of MEHs in CRC chemotherapy are initially demonstrated from the theoretical level， but high-quality clinical evidence is still needed to support it. The present study discussed the efficiency-enhancing and toxicity-reducing effects and application advantages of MEHs in CRC patients during chemotherapy to provide references for the clinical promotion of MEHs.

Objective:To observe the role of Huaiqihuang Granules (HQ) in the long-term management of bronchial asthma in young children, and the effective effect on concomitant rhinitis.Methods:A prospective real-world multicenter study was conducted in children aged 2-5 years with asthma diagnosed in the outpatient department (from April 2016 to March 2019)who received either inhaled corticosteroid (ICS)/leukotriene receptor antagonist (LTRA)(control group); inhaled ICS/LTRA plus HQ(combination group), or HQ alone(HQ group). All patients were followed up at week 4, 8, 12 after treatment. The number of days with asthma symptoms, the frequency of severe asthma attacks, the level of asthma control, and the days with rhinitis symptoms in the last 4 weeks were recorded. Differences before and after treatment, and those among groups after treatment were compared using Kruskal- Wallis H test or Wilcoxon rank-sum test. Results:A total of 2 234 eligible patients were recruited, and 2 147 cases completed followed-up visits, including 477, 1 374 and 296 cases in the control group, combination group, and HQ group, respectively. After the treatment, all 3 groups showed significant declines in the days with asthma symptoms, frequency of severe asthma attack and the days with rhinitis symptoms (all P<0.01), and the rate of well-controlled asthma increased significantly ( P<0.01). It lasted until the end of follow-up. Among groups, patients in the combination group showed significantly less days of asthma symptoms than those of the other 2 group at week 8 and 12[0(0, 0.9) d vs.0(0, 0.3) d, P<0.05; 0(0, 0.1) d vs. 0(0, 1.0) d, P<0.01]. Patients in the combination group and HQ group showed a significantly lower rate of severe asthma attacks than that of the control group at week 12 [0(0, 1), 0(0, 1), 0(0, 2), all P<0.05]. The well-controlled rate of asthma in the combination group was significantly higher than that of the control group and HQ group at week 8 and 12 (89.6% vs. 85.9% vs.82.1%, H=15.28; 90.9% vs. 84.1% vs. 81.8%, χ2=29.32, all P<0.01). Conclusions:HQ can significantly alleviate symptoms of asthma and rhinitis, severe attack of asthma, and increase the control rate of asthma when used as an additional treatment or used alone.
