Objective To investigate the criteria for assessing the clinical therapeutic effect of chronic urticaria in China.Methods The application of criteria for assessing the clinical therapeutic effect of chronic urticaria in China and their applicable scope were analyzed by frequency analysis and K-means clustering analysis, respectively.Results The criteria for assessing symptoms and therapeutic effect were different in the 857 papers included in this study. SSRI was used in 549 (64.17) out of the 857 papers included in this study.K-means clustering analysis showed that the applicable scope of SSRI with curative rate ( 100%≥SSRI>90%) , improvement rate ( 90%≥SSR<60%) , Significant effect rate (60%≥SSRI>20%) , and no response rate (20%≥SSR≥0%) as its criteria was wider than that of frequency analysis.Conclusion The criteria for the clinical assessment of chronic urticaria and its drug treatment effect should be unified and standardized.

OBJECTIVETo investigate the clinical effects of close reduction and percutaneous minimally invasive fixation in the treatment of proximal humerus fractures.

METHODSFrom April 2008 to March 2010, 28 patients with proximal humerus fracture were treated with close reduction and percutaneous minimally invasive fixation. There were 21 males and 7 females, ranging in age from 22 to 78 years,with an average of 42.6 years. The mean time from suffering injuries to the operation was 1.7 d. Nineteen cases caused by falling down, 9 cases by traffic accident. The main clinical manifestation was swelling, pain and limited mobility of shoulders. According to Neer classification, two part fractures were in 17 cases and three part fractures in 11 cases. The locking proximal humerus plate was used to minimally fixation through deltoid muscle under acromion. The operating time,volume of blood loss, the length of incision and Constant-Murley assessment were applied to evaluate the therapeutic effects.

RESULTSThe mean operating time was 40 min, the mean blood loss was 110 ml, and the mean length of incision was about 5.6 cm. The postoperative X-ray showed excellent reduction and the plate and screws were successfully place. Twenty-eight patients were followed up for 6 to 24 months (averaged 14.2 months). The healing time ranged from 6 to 8 weeks and all incision was primarily healed. There were no cases with necrosis head humerus, 24 cases without omalgia, and 4 cases with o-malgia occasionally. All the patients can complete the daily life. The mean score of Constant-Murley assessment was 91.0 +/- 5.8, 24 cases got an excellent result, 3 good and 1 fair.

CONCLUSIONClose reduction and percutaneous minimally invasive fixation, not only can reduce surgical invasive, but also guarantee the early function activities. It has the advantages of less invasive, fixed well and less damage of blood circulation.

This study aims to explore the influence of Polygonati Rhizoma on the pyroptosis in the rat model of diabetic macroangiopathy via the NOD-like receptor thermal protein domain associated protein 3(NLRP3)/cysteinyl aspartate specific proteinase-1(caspase-1)/gasdermin D(GSDMD) pathway. The rat model of diabetes was established by intraperitoneal injection of streptozotocin(STZ) combined with a high-fat, high-sugar diet. The blood glucose meter, fully automated biochemical analyzer, hematoxylin-eosin(HE) staining, enzyme-linked immunosorbent assay, immunofluorescence, immunohistochemistry, and Western blot were employed to measure blood glucose levels, lipid levels, vascular thickness, inflammatory cytokine levels, and expression levels of pyroptosis-related proteins. The mechanism of pharmacological interventions against the injury in the context of diabetes was thus explored. The results demonstrated the successful establishment of the model of diabetes. Compared with the control group, the model group showed elevated levels of fasting blood glucose, total cholesterol(TC), triglycerides(TG) and low-density lipoprotein cholesterol(LDL-c), lowered level of high-density lipoprotein cholesterol(HDL-c), thickened vascular intima, and elevated serum and aorta levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β) and interleukin-18(IL-18). Moreover, the model group showed increased NLRP3 inflammasomes and up-regulated levels of caspase-1 and GSDMD in aortic vascular cells. Polygonati Rhizoma intervention reduced blood glucose and lipid levels, inhibited vascular thickening, lowered the levels of TNF-α, IL-1β, IL-18 in the serum and aorta, attenuated NLRP3 inflammasome expression, and down-regulated the expression levels of caspase-1 and GSDMD, compared with the model group. In summary, Polygonati Rhizoma can slow down the progression of diabetic macroangiopathy by inhibiting pyroptosis and alleviating local vascular inflammation.

OBJECTIVETo investigate the prognostic value of morphology and Hans classification in diffuse large B cell lymphoma（DLBCL）.

METHODSClinical data of 249 patients diagnosed with DLBCL in our hospital and Hangzhou Xixi hospital during Jan 2006 to Dec 2016 were analyzed retrospectively. These patients were classified into 3 groups: immunoblastic variant（IB） group, centroblastic variant（CB） group and others group according to the cell morphology. And DLBCL was also divided into GCB（germinal center B-cell-like）or non-GCB（non-germinal center B-cell-like） group by analyzing the expression of CD10, BCL6 and MUM1 (GCB: CD10 ,BCL6,MUM1/CD10,BCL6,MUM1；non-GCB：CD10,BCL6,MUM1/CD10,BCL6,MUM1).

RESULTSThe univariate analysis displayed that the age，LDH level，IPI，IB，non-GCB，B-symptoms and rituximab all could influence the OS and EFS, the CR rate of CB subtype patients was significantly higher than that of the patients with IB subtype （68.3% vs 38.9%)(P=0.02）. IB subtype was the in dependent prognostic factor for both EFS and OS in the whole study. In multivariate analysis, IPI and IB were the independent prognostic factors for OS and EFS. IB subtype was also an independent prognostic factor in EFS and OS with or without rituximab. The expression of BCL2 and BCL6 was related with prognosis in R-CHOP, but not in CHOP treated patients. Other markers (CD5, CD10, IRF4/MUM1, HLA-DR and Ki-67 proliferation index) were not of the significant prognostic value for DLBCL. When accepted rituximab, the GCB and non-GCB were not different significantly for prognosis. However, the non-GCB group showed a poor prognosis without using rituximab （EFS P=0.020；OS P=0.020）. Multivariate Cox models showed that OS and EFS were not significantly different between GCB and non-GCB group, however, the IB subtype had a very significantly poor prognosis in OS and EFS (P=0.001, P=0.002). When the analysis was restricted to DLBCL with CB morphology only, no prognostic value was observed in Hans classification.

CONCLUSIONThe subtype of immunoblast is a major risk factor in patients treated with CHOP or R-CHOP. There is a significant association between the Hans classification and the morphologic subclassification. Results of this study have supplemented the data for the prognostic factor of DLBCL and demonstrated that the cytomorphologic diagnosis can be reproducible.
