Objective To evaluate the correlation between thin-section CT morphologic features and pathological vascular invasion in the clinical stage ⅠA peripheral lung adenocarcinoma.Methods The preoperative thin-section CT images,clinical and pathological characteristics of 102 nodules in 98 patients were retrospectively analyzed and divided into two groups according to pathological vascular invasion.Variables including the diameter of tumor(T) and consolidation part (C) in the mix ground glass nodule (mGGN),C/T ratio,morphology and pathological classification were analyzed by two-independent samples Mann-Whitney U test or t test and x2 test or Fisher exact probability test.Variables with significant difference in the univariate analyses were entered into multivariate analysis to explore predictors for vascular invasion.The correlation between these measurements and vascular invasion was evaluated by a ROC analysis.Results All of 102 nodules,36 had pathological vascular invasion and 66 without.The numbers of two groups with speculation,air bronchogram,abnormal vein,vascular convergence,pleural indentation were 30,30;26,26;35,3;35,39;32,39 and the mediandiameter of tumors were 2.1(1.0-3.0),1.2(0.5-3.0) cm respectively.By univariateanalysis,spiculation,air bronchogram,abnormal vein,vascular convergence,pleural indentation,and diameter of tumor were significantly associated with pathological vascularinvasion (P＜0.01).By multivariate logistic analysis,the statistically significant difference were found in speculation and abnormal vein (OR=33.867,8 161.063,P＜0.05).The ROC analysis showed the area under curve,cut-off value,sensitivity and specificity ofthe diameter of tumor and consolidation part of mGGN and C/T ratio were 0.784,2.05 cm,66.7％,78.8％;0.886,1.08 cm,82.4％,90.0％ and 0.861,0.65,79.4％,85.0％ respectively in differentiating tumors with pathological vascular invasion.Conclusion The spiculation sign and abnormal vein are independent predictors for vascular invasion in stage ⅠA peripheral lung adenocarcinoma.

BACKGROUNDDue to the floating of the guideline, there is no evidence-based evaluation index on when to start the blood transfusion for patients with hemoglobin (Hb) level between 7 and 10 g/dl. As a result, the trigger point of blood transfusion may be different in the emergency use of the existing transfusion guidelines. The present study was designed to evaluate whether the scheme can be safely and effectively used for emergency patients, so as to be supported by multicenter and large sample data in the future.

METHODSFrom June 2013 to June 2014, patients were randomly divided into the experimental group (Peri-operative Transfusion Trigger Score of Emergency [POTTS-E] group) and the control group (control group). The between-group differences in the patients' demography and baseline information, mortality and blood transfusion-related complications, heart rate, resting arterial pressure, body temperature, and Hb values were compared. The consistency of red blood cell (RBC) transfusion standards of the two groups of patients with the current blood transfusion guideline, namely the compliance of the guidelines, utilization rate, and per-capita consumption of autologous RBC were analyzed.

RESULTSDuring the study period, a total of 72 patients were recorded, and 65 of them met the inclusion criteria, which included 33 males and 32 females with a mean age of (34.8 ± 14.6) years. 50 underwent abdomen surgery, 4 underwent chest surgery, 11 underwent arms and legs surgery. There was no statistical difference between the two groups for demography and baseline information. There was also no statistical differences between the two groups in anesthesia time, intraoperative rehydration, staying time in postanesthetic care unit, emergency hospitalization, postoperative 72 h Acute Physiologic Assessment and Chronic Health Evaluation II scores, blood transfusion-related complications and mortality. Only the POTTS-E group on the 1 st postoperative day Hb was lower than group control, P < 0.05. POTTS-E group was totally (100%) conformed to the requirements of the transfusion guideline to RBC infusion, which was higher than that of the control group (81.25%), P < 0.01.There were no statistical differences in utilization rates of autologous blood of the two groups; the utilization rates of allogeneic RBC, total allogeneic RBC and total RBC were 48.48%, 51.5%, and 75.7% in POTTS-E group, which were lower than those of the control group (84.3%, 84.3%, and 96.8%) P < 0.05 or P < 0.01. Per capita consumption of intraoperative allogeneic RBC, total allogeneic RBC and total RBC were 0 (0, 3.0), 2.0 (0, 4.0), and 3.1 (0.81, 6.0) in POTTS-E groups were all lower than those of control group (4.0 [2.0, 4.0], 4.0 [2.0, 6.0] and 5.8 [2.7, 8.2]), P < 0.05 or P < 0.001.

CONCLUSIONSPeri-operative Transfusion Trigger Score-E evaluation scheme is used to guide the application of RBC. There are no differences in the recent prognosis of patients with the traditional transfusion guidelines. This scheme is safe; Compared with doctor experience-based subjective assessment, the scoring scheme was closer to patient physiological needs for transfusion and more reasonable; Utilization rate and the per capita consumption of RBC are obviously declined, which has clinical significance and is feasible. Based on the abovementioned three points, POTTS-E scores scheme is safe, reasonable, and practicable and has the value for carrying out multicenter and large sample clinical researches.

INTRODUCTION: Associations of variations in PLA2R1 and HLA-DQA1 genes with susceptibility to idiopathic membranous nephropathy (IMN) have been well documented. Association with spontaneous remission, however, is poorly defined in the Chinese Han population. METHODS: A Chinese cohort of 117 IMN patients and 138 healthy controls were recruited between July 2009 and November 2019. Case-control studies for single-nucleotide polymorphisms (SNPs) within HLA-DQA1 (rs2187668) and PLA2R1 (rs35771982, rs4664308, rs3749117, rs3749119) genes were performed. The contributions of these polymorphisms to predict susceptibility, titre of autoantibodies against the M-type phospholipase A2 receptor (anti-PLA2R1), glomerular PLA2R1 expression, and spontaneous remission were analysed. RESULTS: We found that variations in PLA2R1 (SNPs rs35771982, rs4664308, rs3749117) were strongly associated with IMN susceptibility, while SNP (rs2187668) within HLA-DQA1 did not increase the risk of IMN. All SNPs in PLA2R1 and HLA-DQA1 were not statistically associated with anti-PLA2R1 titre, glomerular PLA2R1 expression and spontaneous remission after Bonferroni correction ( CONCLUSION This study confirms that variations in PLA2R1 (SNPs rs35771982, rs4664308, rs3749117) are risk factors for IMN. We found excellent association of serum albumin level, anti-PLA2R1 titre and glomerular PLA2R1 positivity with non-spontaneous remission in IMN.

Objective To study the molecular characteristic of norovirus in 3 outbreaks of gastroenteritis in Zhejiang province. Methods During January 2008 and December 2009, fecal specimens of patients were collected from 3 outbreaks of acute viral gastroenteritis. Noroviruses were detected by Real-time RT-PCR. Part of the positive samples were randomly selected and detected by RT-PCR. PCR products were sequenced. Sequence analysis was undertaken based on partial sequence of RNA dependent RNA polymerase(RdRp)and capsid protein gene. Some positive samples were amplified by 3' RACE(rapid amplification of cDNA 3' ends), 3200 bp in length. The exact whole ORF2, ORF3 and 3' untranslation regions(UTR)gene of norovims were identified. Results There were in total 3 outbreaks of viral gastroenteritis caused by norovirus being reported. A total of 62 stools were obtained from cases with acute gastroentefitis. Noroviruses were detected in 41 cases including 27 strains of genogroup Ⅰ norovirus and 9 strains of genogroup Ⅱ norovirus, 5 strains of genogroup Ⅰ + Ⅱ norovirus. Four genotypes including G Ⅰ .8, G Ⅱ .b, G Ⅰ .2/0 Ⅰ .6 recombination together with co-infection of G Ⅰ .8 and G Ⅱ .b were detected. Conclusion Norovirus was confirmed as the major cause of outbreaks of viral gastroenteritis in Zhejiang province and multiple genotype of norovirus were identified from the outbreaks. It was the first time to have found a recombinant of G Ⅰ .6 capsid and G Ⅰ .2 polymerase norovims as well as the co-infection of G Ⅰ .8 and G Ⅱ .b norovirus in the same sample.

Oral squamous cell carcinoma (OSCC) has a high incidence of cervical micrometastases and sometimes metastasizes contralaterally because of the rich lymphatic intercommunications relative to submucosal plexus of oral cavity that freely communicate across the midline, and it can facilitate the spread of neoplastic cells to any area of the neck consequently. Clinical and histopathologic factors continue to provide predictive information to contralateral neck metastases (CLNM) in OSCC, which determine prophylactic and adjuvant treatments for an individual patient. This review describes the predictive value of clinical-histopathologic factors, which relate to primary tumor and cervical lymph nodes, and surgical dissection and adjuvant treatments. In addition, the indications for elective contralateral neck dissection and adjuvant radiotherapy (aRT) and strategies for follow-up are offered, which is strongly focused by clinicians to prevent later CLNM and poor prognosis subsequently.

OBJECTIVETo study the expression of anaplastic lymphoma kinase (ALK) and survivin proteins in anaplastic large cell lymphoma (ALCL) and there clinical significance.

METHODSThe morphologic characteristics were studied by routine light microscopy. Immunohistochemical staining for ALK and survivin proteins was performed using LSAB method.

RESULTSALK protein was positive in 51 cases (63%) and negative in 30 cases (37%) of the 81 cases of ALCL studied. The prognosis of patients with ALK protein expression was better than those without ALK expression (P < 0.05). As for survivin protein, there were various degrees of expression in all the 77 ALCL cases studied. High level of survivin protein expression was observed in 33 cases (42.9%), while low level of expression was seen in 44 cases (57.1%). The expression of survivin protein did not correlate with that of ALK protein (P > 0.05). The survival rate was significantly lower in patients with high survivin protein expression (P < 0.05). In cases with ALK protein expression, the prognosis was less favorable if there was also high co-expression of survivin protein (P < 0.05). In ALK protein negative cases, prognosis did not significantly correlate with the expression of survivin protein (P > 0.05). In addition, multivariate analysis confirmed the prognosis value of ALK protein expression, survivin protein expression and constitutional symptoms.

CONCLUSIONSurvivin protein expression can serve as an independent prognostic predictor of unfavorable clinical outcome in patients with ALCL, especially when ALK protein is positive.

Objective: To investigate the effect of 1q21 amplification (1q) on the therapeutic response and prognosis of bortezomib(Btz) in the treatment of newly diagnosed multiple myeloma (MM) patients. Methods: A total of 180 newly diagnosed MM were included for analyses of clinical characteristics, cytogenetics, objective response rate (ORR), progression-free survival (PFS) and overall survival (OS), retrospectively. Gene expression profiling (GEP) was analyzed using publicly available R2 platform. Results: ① In 180 patients, 1q was found in 51.1% cases. Of them, 174 patients had complete follow-up data, including 88 cases with 1q and 86 without 1q (non-1q). ②Incidence of 1q was positively associated with percentage of IGH rearrangement (72.2%, P=0.017) and 1p deletion (1p) (27.8%, P=0.040). ③ The median PFS was 15.0 and 20.3 months for the 1q group and non-1q group, and the median OS was 29.4 and 44.0 months, respectively. Both PFS and OS of 1q group was significantly shorter than those of the non-1q group (P=0.029 and 0.038, respectively). Multivariate analysis further revealed that 1q was an independent prognostic factor for both PFS (HR=1.910, 95% CI 1.105-3.303, P=0.020) and OS (HR=2.353, 95% CI 1.090-5.078, P=0.029). ④ In 91 evaluable cases with 1q, very good partial remission (VGPR) rate was higher after treatment with Btz than those without Btz (62.1% vs 40.0%, P=0.032). Of note, the patients with 1q who received auto-HSCT after induction with Btz had significantly longer PFS than those without auto-HSCT (19 months vs 13 months, P=0.048). ⑤GEP analysis revealed that 1q21 amplification predominantly up-regulated expression of >50% genes within 1q21 region, and also altered expression of 28% genes in chromosome 1 and 10% genes in whole genome, particularly related to DNA repair and cell cycle. Conclusions: 1q is an independent adverse prognostic factor in patients with newly diagnosed MM. It is often associated with 1p deletion and IGH rearrangement. Patients with 1q respond well to Btz-based regimen, but they fail to gain long-term benefit from this treatment itself. However, auto-HSCT following Btz induction might improve survival of patients with 1q, suggesting a potential strategy to treat this high-risk subset of MM. GEP analysis warrants further attention in understanding the mechanisms underlying the high-risk of 1q.

The objective of this study is to fully investigate the therapeutic effect and mechanisms of action of Gegen Qinlian decoction (GD) on type 2 diabetes mellitus (type 2 DM). A rat model of type 2 DM was established with the combination of high-fat diet and multiple low doses of streptozotocin (STZ). Biochemical indicators related to glucose metabolism disorders, insulin resistance, oxidative stress were observed. The type 2 DM rats were administrated with GD for 80 days, the above-mentioned indexes were detected. The results indicated that the hepatic glycogen synthesis level was promoted, fasting blood glucose level and fasting blood insulin level were significantly reduced, insulin sensitivity index was significantly improved; the level of superoxide dismutase (SOD) was increased and the level of malondialdehyde (MDA) was reduced; pathologic morphology of pancreas and kidney was ameliorated in the GD group. It was indicated that the therapeutic mechanisms of action of GD on type 2 DM might be related to its effect of ameliorating glucose metabolism disorders, relieving insulin resistance, increasing the tissues' sensitivity to insulin, improving the antioxidative ability of living system, GD has therapeutic effect on type 2 DM and protective effects against damaged pancreatic function.

OBJECTIVE: To investigate the incidence of neonatal asphyxia and possible contributing factors for the development of severe asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture, China. METHODS: A total of 16 hospitals in Hubei Enshi Tujia and Miao Autonomous Prefecture were selected as research centers. A retrospective analysis was performed for the clinical data of 22 294 live births in these 16 hospitals from January to December, 2016 to investigate the incidence rate of neonatal asphyxia and possible contributing factors for the development of severe asphyxia. RESULTS: Of the 22 294 neonates born alive, 733 (3.29%) were diagnosed with neonatal asphyxia, among whom 627 had mild asphyxia and 106 had severe asphyxia. The neonates with low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight had a higher incidence of severe asphyxia (P<0.05). CONCLUSIONS The incidence rate of neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture is higher. Low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight may be related to the development of severe neonatal asphyxia.
