To report a case of nonbullous neutrophilic lupus erythematosus. A 57-year-old male patient presented with recurrent erythematous pruritic papules and plaques on the trunk and extremities for over 10 years. Skin examination revealed scattered urticaria-like papules and plaques on the trunk and limbs, with thin scales on the edge of some lesions. Laboratory tests showed positive antinuclear antibodies at a titer of 1∶320 (granular type), anti-Sj?gren syndrome A (SSA) antibodies (++), anti-SSB antibodies (+++), anti-Ro-52 antibodies (+++), and anti-neutrophil cytoplasmic antibodies at a level of 369.09 RU/ml (reference range: 0 - 20 RU/ml). Histopathological analysis of the skin lesions on the back revealed epidermal hyperkeratosis in a basket-like shape, liquefaction degeneration of basal cells, infiltration of numerous neutrophils in the superficial dermis with karyorrhexis, perivascular infiltration of lymphocytes in the superficial and middle dermis, and extensive extracellular mucin deposition throughout the dermis. Finally, the patient was diagnosed with nonbullous neutrophilic lupus erythematosus.

Objective:To explore the sleep status and impact factor analysis of patients in clinical trials of antineoplastic drugs, and provide a basis for improving the sleep status and impact analysis of patients in clinical trials of antineoplastic drugs.Methods:From April to May 2023, 107 oncology patients in the Phase I Clinical Trial Ward of the Affiliated East Hospital of Tongji University were selected as the research objects by convenient sampling method. The general information questionnaire, Pittsburgh Sleep Quality Index Scale (PSQI), Numeric rating scale (NRS), Generalized Anxiety Disorder Scale (GAD-7) and Depression Self-Ration Tool Scale (PHQ-9). Multivariate Logistic regression analysis methods were used to carry out a cross-sectional investigation and the relevant factors affecting patients′sleep.Results:Totally 103 questionnaires were effectively collected. The 103 patients′ age ranged from 20 to 75 years old, including 61 males and 42 females. 47.57% (49/103) patients in clinical trials of antineoplastic drugs had abnormal sleep. The average score of patients (PSQI) (7.66 ± 3.93) was higher than the average score of the domestic norm (3.88 ± 2.52), and there was significant statistical difference ( t = 9.76, P<0.01). Logistic regression analysis showed that pain ( OR = 3.004, 95% CI 1.135-7.948, P<0.05) and trial cycle ( OR = 0.432, 95% CI 0.191-0.978, P<0.05) were significant risk factors for abnormal sleep quality. Conclusions:The incidence of abnormal sleep quality in patients of clinical trials of antineoplastic drugs is high, but the sleep quality is poor. The factors that affect the sleep quality of patients in clinical trials of antineoplastic drugs are mainly related to the patient′s trial cycle and cancer pain. According to these characteristics, individualized programs should be developed to improve the sleep quality of patients with advanced cancer, so as to improve the quality of life of patients with advanced cancer.

Objective To explore the regulatory effect of miR-6838-5p on DDR1 gene expression and proliferation of breast cancer cells.Methods The expression levels of miR-6838-5p in normal breast epithelial cells and breast cancer cells were detected using qRT-PCR,and the potential target genes of miR-6838-5p was predicted using TargetscanV 8.0.Double luciferase reporter gene experiment was performed to verify the binding between miR-6838-5p and DDR1.Breast cancer MCF-7 cells were transfected via liposome,miR-6838-5p mimic,miR-6838-5p inhibitor,DDR1 siRNA,DDR1-overexpresisng vector,or both miR-6838-5p mimic and DDR1-overexpressing vector,and the changes in cell proliferation were examined with CCK-8 and EdU assays;Western blotting was used to detect the expression of DDR1.The mediating role of DDR1 in miR-6838-5p overexpression-induced inhibition of MCF-7 cell proliferation was verified in a nude mouse model bearing MCF-7 cell xenografts.Results The expression of miR-6838-5p was significantly lower in breast cancer cells than in normal breast epithelial cells.In MCF-7 cells,miR-6838-5p overexpression induced significant inhibition of cell proliferation.Dual luciferase reporter gene experiment demonstrated a binding relationship between miR-6838-5p and DDR1(P<0.01).Western blotting showed that miR-6838-5p overexpression significantly lowered DDR1 expression in MCF-7 cells,and DDR1 overexpression promoted proliferation of the cells;co-transfection of the cells with DDR1-overexpressing vector significantly attenuated the inhibitory effect of miR-6838-5p mimic on cell proliferation.In the tumor-bearing nude mice,the xenografts overexpressing miR-6838-5p showed a significantly smaller volum with obviously the expression of DDR1.Conclusion Overexpression of miR-6838-5p inhibits breast cancer cell proliferation by regulating DDR1 expression.

Objective To analyze the factors affecting the prognosis of patients with pulmonary sarcomatoid carcinoma (PSC) and construct a nomogram prediction model for the prognosis of PSC patients. Methods Based on the SEER database, 1671 patients diagnosed as PSC from 1988 to 2015 were collected and divided into modeling group and validation group according to the ratio of 7:3. Univariate and multivariate Cox regression analysis were performed in the modeling group to explore independent risk factors affecting the prognosis and construct a nomogram survival prediction model. The consistency index and calibration curve were used for verification in the modeling group and the test module respectively. Results Age, gender, histological type, TNM stage, tumor diameter > 50mm, surgery, radiotherapy and chemotherapy were independent factors that affected the prognosis of PSC patients. The nomogram prediction model was constructed and verified based on independent factors. The C indexes of the modeling group and the test model were 0.790 (95%CI: 0.776-0.804) and 0.781 (95%CI: 0.759-0.803), respectively. The calibration curves of the modeling group and the test model indicated that the predicted survival rate was basically the same as the actual survival rate. Conclusion The nomogram prediction model constructed based on the results of multivariate analysis can predict the prognosis of PSC patients, and has high accuracy and consistency.

Objective To analyze the mortality risk and evaluate the curative effects of surgery and non-surgery on NSCLC with diameter > 7.0 cm. Methods We collected the data of NSCLC patients with diameter > 7.0 cm from 2010 to 2015 from the SEER database. The 1, 2, 3-year survival rates were analyzed by life table method. Overall survival curve was estimated by Kaplan-Meier method. Univariate and multivariate Cox regression models were used to analyze the independent prognostic factors. Results The 1, 2, 3-year survival rates were 51.8%, 33.0% and 25.0%, respectively. In univariate and multivariate analyses, tumor size, N stage and treatment were the independent prognostic factors (P < 0.001). Conclusion Surgery is benefited for the prognosis of stage N0-N1 NSCLC patients with diameter > 7.0 cm. And for stage N2 NSCLC patients with diameter 7.0-9.0 cm, surgical treatment has advantages in improving the prognosis. Surgical and non-surgical patients with tumor diameter ≥9.0 cm or lymph node N3 stage have no statistically significant differences in prognosis. In addition, palliative treatment does not improve the prognosis of patients.

Objective:To evaluate the efficacy and safety of recombinant human tumor necrosis factor-α receptorⅡ: IgG Fc fusion protein (rhTNFR:Fc) in the treatment of drug-induced toxic epidermal necrolysis (TEN) .Methods:From 2009 to 2018, 22 patients with TEN were enrolled from 8 centers such as the Second Affiliated Hospital of Soochow University, including 10 males and 12 females, whose age ranged from 22 to 75 years. These patients were subcutaneously injected with rhTNFR:Fc at a dose of 25 mg once every 3 days for 6 - 8 consecutive sessions, and the initial dose was doubled. The drug eruption area and severity index (DASI) score and DASI improvement indices (DASI50, DASI75 and DASI90) were assessed before treatment and on days 4, 7, 10, 13, 16, 19, 22 and 25 after treatment; cytometric bead array (CBA) technology was used to detect the level of tumor necrosis factor (TNF) -α in peripheral blood and blister fluid samples. During the treatment, body temperature, rash changes, liver and kidney function of patients were monitored, and adverse reactions were recorded. Statistical analysis was carried out by using repeated measures analysis of variance, paired t test and Pearson correlation analysis. Results:Of the 22 patients, the temperature stopped rising in 20 patients without infections 24 - 72 hours after the first treatment, and returned to normal after 48 - 120 hours. Among the 22 patients, new blisters stopped appearing 24 - 48 hours after the first treatment, the skin color changed from bright red to dark purple after 48 - 96 hours, and most skin lesions subsided after 2 weeks. After 2 - 4 weeks of treatment, levels of alanine aminotransferase and aspartate aminotransferase returned to normal in 19 patients with abnormal liver function. After 4 - 13 days of treatment, levels of creatinine and urea nitrogen stopped rising in 7 patients with abnormal renal function. During the treatment, the DASI score of the 22 patients gradually decreased ( F = 532.81, P < 0.01) , from 53.64 ± 8.67 before treatment to 2.05 ± 1.21 on day 25 after treatment ( t = 26.60, P < 0.001) . On day 10 after treatment, 22 patients (100%) achieved DASI50; on day 19, 22 (100%) achieved DASI75; on day 25, 20 (90.90%) achieved DASI90. The level of TNF-α in peripheral blood of the 22 patients gradually decreased along with the extension of treatment duration, from 33.95 ± 27.90 ng/L before treatment to 2.38 ± 0.79 ng/L on day 25. Before treatment, the level of TNF-α in blister fluid of 15 patients was 111.99 ± 99.41 ng/L, and the ratio of blister-fluid TNF-α level to peripheral blood TNF-α level was 1.83 - 28.21. Before treatment, no correlation was observed between the serum level of TNF-α and DASI score in the 22 patients ( P = 0.10) , while the blister-fluid TNF-α level was positively correlated with DASI score in the 15 patients ( r = 0.59, P = 0.02) . No acute adverse reactions were observed during the treatment. All the 22 patients completed the treatment and were discharged with complete recovery. During 6 months of follow-up after discharge, no recurrence or any complication was observed. Conclusion:rhTNFR:Fc is effective and safe for the treatment of drug-induced TEN.

Objective:To search for circulating complement-related proteins that predict hypertensive disorders of pregnancy (HDP) based on reports of the development of gestational hypertension and proteinuria and to investigate the role of the complement system in the development of HDP.Methods:A nested case-control study was used, the serum samples of pregnant women who had been given birth or cesarean section in Guangzhou Women and Children′s Medical Center from November 2014 to March 2017 were collected. A total of 60 HDP and 60 normal pregnant women were included and matched 1∶1 by age and gestational week. Unlabeled mass spectrometry was used to screen the differential expression of complement factors in serum samples of 12 pairs of HDP patients and normal pregnancy collected before 20 weeks of pregnancy, and another 48 pairs of serum samples of HDP patients and normal pregnant women were used for preliminary verification. It was selected when the fold change (FC) of complement factor expression was>1.2 or <0.8 and P<0.05. ROC curve was used to evaluate the diagnostic value of corresponding factors. Results:FC of serum C1s, C8 beta chain (C8β) and C1 inhibitor (C1-INH) of HDP patients were 1.19, 1.23, 0.73 ( t=2.07, 2.06, -3.40; P<0.05), respectively. FC of serum C1s, C8 β, C1-INH, factor H-related protein 5 (CFHR5), clusterin (CLU), and C-reactive protein (CRP) of PE patients were 1.39, 1.50, 0.72, 2.49,4.38, and 1.82 respectively ( t=4.36, 5.61, -3.70, 6.82, 8.70, 7.27; P<0.05).The AUC of combining C1s, C8 β and C1-INH was 0.89 in HDP. The AUC of CFHR5, CLU, and CRP in preeclampsia was 0.88, 0.92, and 0.91. Conclusions:Before HDP, the activation and regulation of classic complement pathway and alternative pathway were disordered in pregnant women. The combined detection of complement C1s, C8 β and C1-INH is expected to be used in the prediction of HDP, and CFHR5, CLU, and CRP are expected to be used in the prediction of preeclampsia.
