Objective: The purpose of our study was to investigate the predictive abilities of clinical and computed tomography (CT)features for outcome prediction in patients with coronavirus disease (COVID-19). Materials and Methods: The clinical and CT data of 238 patients with laboratory-confirmed COVID-19 in our two hospitalswere retrospectively analyzed. One hundred sixty-six patients (103 males; age 43.8 ± 12.3 years) were allocated in thetraining cohort and 72 patients (38 males; age 45.1 ± 15.8 years) from another independent hospital were assigned in thevalidation cohort. The primary composite endpoint was admission to an intensive care unit, use of mechanical ventilation, ordeath. Univariate and multivariate Cox proportional hazard analyses were performed to identify independent predictors. Anomogram was constructed based on the combination of clinical and CT features, and its prognostic performance wasexternally tested in the validation group. The predictive value of the combined model was compared with models built on theclinical and radiological attributes alone. Results: Overall, 35 infected patients (21.1%) in the training cohort and 10 patients (13.9%) in the validation cohortexperienced adverse outcomes. Underlying comorbidity (hazard ratio [HR], 3.35; 95% confidence interval [CI], 1.67–6.71;p < 0.001), lymphocyte count (HR, 0.12; 95% CI, 0.04–0.38; p < 0.001) and crazy-paving sign (HR, 2.15; 95% CI, 1.03–4.48;p = 0.042) were the independent factors. The nomogram displayed a concordance index (C-index) of 0.82 (95% CI, 0.76–0.88),and its prognostic value was confirmed in the validation cohort with a C-index of 0.89 (95% CI, 0.82–0.96). The combinedmodel provided the best performance over the clinical or radiological model (p < 0.050). Conclusion Underlying comorbidity, lymphocyte count and crazy-paving sign were independent predictors of adverseoutcomes. The prognostic nomogram based on the combination of clinical and CT features could be a useful tool for predictingadverse outcomes of patients with COVID-19.

OBJECTIVE: To study the clinical features of severe type 7 adenovirus pneumonia in children. METHODS: A retrospective analysis was performed for the clinical data of children who were diagnosed with severe type 7 adenovirus pneumonia from February to June, 2019. RESULTS: Among the 45 children, the male/female ratio was 3:2 and the median age was 14 months. All children had repeated fever, cough, and pulmonary moist rales, and the mean duration of fever was 14±4 days. The median time from fever to dyspnea was 8 days, and the time from fever to mechanical ventilation was 11.6±2.5 d. There was no significant increase in white blood cell count, with neutrophils as the main type. There were slight reductions in hemoglobin and albumin, while platelet and fibrinogen remained normal. There were increases in aspartate aminotransferase, lactate dehydrogenase, procalcitonin, and C-reaction protein. The detection rate of mixed pathogens was 84%. Effusion in both lungs was the major change on chest imaging (64%). Bronchoscopic manifestations were endobronchitis, tracheomalacia, and plastic bronchitis. The incidence rate of respiratory complications was 100%, and extrapulmonary complications mainly involved the circulatory system (47%), digestive system (36%), and nervous system (31%). Among the 45 children, 16 were administered with 400 mg/kg intravenous immunoglobulin (IVIG) daily for 5 days, with a mean duration of fever of 16±5 days, and 29 were administered with 1 g/kg IVIG daily for 2 days, with a mean duration of fever of 13±4 days; there was a significant difference in the mean duration of fever between the two groups (P=0.046). The overall mortality rate was 11%. CONCLUSIONS Severe type 7 adenovirus pneumonia in children has severe conditions, with a high incidence rate of complications and a high mortality rate, so it should be diagnosed and treated as early as possible.

Objective:To observe serum levels of high sensitive C reactive protein(hsCRP),interleukin(IL)-6, tumor necrosis factor(TNF)-α and hepatocyte growth factor(HGF)in patients with ischemic cerebrovascular dis-ease(ICVD),and analyze their correlation with blood lipids and anticardiolipin antibody(ACA)levels.Methods:A total of 45 ICVD patients treated in our hospital from Mar 2015 to Aug 2016 were regarded as ICVD group.An-other 45 non-ICVD patients treated in our hospital during the same period were regarded as non-ICVD control group.Serum levels of hsCRP,IL-6,TNF-α,HGF,blood lipids and ACA were observed and compared between two groups,and correlation among serum levels of hsCRP,IL-6,TNF-α and HGF,blood lipids and ACA levels were analyzed in ICVD patients.Results:Compared with non-ICVD control group,there were significant rise in se-rum levels of hsCRP[(4.69 ± 1.31)mg/L vs.(8.87 ± 1.56)mg/L],IL-6[(12.17 ± 4.33)mg/L vs.(34.26 ± 5.15)mg/L],TNF-α[(28.45 ± 2.18)pg/ml vs.(48.35 ± 3.15)pg/ml],HGF[(502.34 ± 15.36)pg/ml vs. (876.25 ± 18.15)pg/ml],ACA[(4.11 ± 0.65)IU/L vs.(7.89 ± 1.02)IU/L],total cholesterol[(4.68 ± 1.12) mmol/L vs.(5.57 ± 1.21)mmol/L],low density lipoprotein cholesterol[(2.62 ± 0.49)mmol/L vs.(3.24 ± 0.87) mmol/L]and triglyceride[(1.42 ± 0.31)mmol/L vs.(1.84 ± 0.37)mmol/L],and significant reduction in serum level of high density lipoprotein cholesterol[(1.28 ± 0.25)mmol/L vs.(1.02 ± 0.22)mmol/L]in ICVD group,P=0.001 all.Pearson correlation analysis indicated that serum levels of hsCRP,IL-6,TNF-α and HGF were signifi-cant positively correlated with serum levels of ACA,TC,LDL-C and TG(r=0.468~0.632,P<0.05 or <0.01), and significant inversely correlated with HDL-C level(r= -0.571~ -0.511,P<0.05 or < 0.01)in ICVD pa-tients.Conclusion:Serum levels of hsCRP,IL-6,TNF-α and HGF significantly rise in ICVD patients,and they are closely correlated with levels of blood lipids and ACA,which can serve as important indexes monitoring ICVD.

Drug resistance of multiple myeloma(MM) has become more and more common, and greatly decreased the survival rate of these patients. The occurence of drug-resistance involves in many factors such as bone marrow microenveronment, tumor cell self-metabolism, cytokines, specific targets and so on. In this review, the potential mechanisms of resistance to glucocorticoid/proteasome inhibitor/immunomodulatory druges are briefly expounded in the aspect of tumor cell self-metabolism, including the changes of heat slock protein expression, mRNA expression, related cytokine levels and down-regulation of thalidomid-effecting site CRBN expression. In this review, the researches on the effect of histone deacetylase inhibitors(HDACi) combined with glucocorticoid, proteasome inhibitors, immunomodulatory drugs and monoclonal antibodies on multiple myeloma, specially, drug-resistant multiple myeloma are also summarized.

Objective The active ingredient was used as index to optimize the extraction and enrichment process of anti-in-flammatory and analgesic active-fraction(ARF)of Dianbaizhu. Methods Methyl salicylate triglycoside-B was chosen as index com-ponent to extract and enrich methyl salicylate glycosides. Extraction and elution solvents were optimized.

Conclusion The extraction and enrichment process of ARF is stable and repeatable.

PURPOSE: The objective was to determine the characteristics and prognostic factors of 86 Chinese patients with trisomy 8 aberrations and compare the prognostic value of International Prognostic System (IPSS) and Revised IPSS (IPSS-R) in this cohort. MATERIALS AND METHODS: A total of 86 cases diagnosed with primary myelodysplastic syndromes (MDS) with isolated tr8 or with tr8 and other additional cytogenetic aberrations diagnosed and treated at the Union Hospital, Tongji Medical College of Huazhong University of Science and Technology between July 2002 and March 2013 were reviewed. RESULTS: The median survival of the entire group was 23.0 months, and acute myeloid leukemia (AML) developed in 43% (37/86) patients within the follow up time. The univariate analysis revealed that overall survival (OS) was correlated with age, thrombocytopenia, absolute neutrophil count, marrow blasts, cytogenetic status and red blood cell transfusion at diagnosis, and the multivariate analysis revealed that age, marrow blasts, cytogenetic status and transfusion dependence were independent parameters for the OS. The cytogenetic complexity and marrow blasts had the strongest impact on the AML transformation by multivariate analysis. Comparing the two prognostic systems, both two systems could successfully discriminate risk groups for survival. IPSS-R was more refined than IPSS for predicting OS, but had no advantage in predicting the risk of AML development. CONCLUSION: This study confirmed the influence of clinical factors on the prognosis of 86 Chinese MDS patients with trisomy 8. In addition, IPSS-R can further refine prognostic discrimination in the IPSS risk categories.

OBJECTIVETo compare the clinical efficacy in the treatment of allergic rhinitis (AR) of lung qi deficiency and cold syndrome between Jin's three-needle therapy and western medication.

METHODSSixty-six patients were randomized into an acupuncture group and a western medication group, 33 cases in each one. In the acupuncture group, acupuncture was applied at three-nose points [Yingxiang (LI 20), Shangyingxiang (EX-HN 8) and Yintang (GV 29); Cuanzhu (BL 2) was added for frontal headache] and three-back points [Dazhu (BL 11), Fengmen (BL 12) and Feishu (BL 13)], once every day. Ten treatments made one session. Two sessions of treatment were required. In the western medication group, desloratadine oral suspension was prescribed, 5 mg each time, once a day, for 20 days. The scores of the symptoms and physical signs in AR patients as well as the clinical efficacy were observed between the two groups.

RESULTSThe total effective rate was 93.9% (31/33) in the acupuncture group, which was better than 72.7% (24/33) in the western medication group (P < 0.05). After treatment, the scores of AR symptoms and physical signs as well as the total score were all reduced compared with those before treatment in the two groups (all P < 0.01). The score of every item in the acupuncture group was lower than that in the western medication group after treatment (score of symptoms: 4.70 +/- 2.07 vs 6.55 +/- 2. 69, score of physical signs: 0.85 +/- 0.67 vs 1.45 +/- +0.62, total score: 5.36 +/- 2.70 vs 8.00 +/- 2.91, all P < 0.01).

CONCLUSIONJin's three-needle therapy achieves superior efficacy on AR of lung-qi deficiency and cold syndrome, which is better than desloratadine oral suspension.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.
