Objective To compare the clinicopathological features of Borrmann type Ⅳ gastric cancer with other gastric cancer and explore prognostic factors of the patients with Borrmann type Ⅳ cancer.Methods We retrospectively reviewed the clinical data of 671 advanced gastric cancer patients.They were divided into 2 groups:Borrmann type Ⅳ (64 cases) and other macroscopic Borrmann types of cancer (607 cases).Their clinicopathologic characteristics and overall survival data were analyzed.Results Age,sex,tumor size,tumor location,lymph node metastasis,distant metastasis,TNM classification were discrepant between Borrmann type Ⅳ and other macroscopic Borrmann types of cancer.The 5-year survival rate of Borrmann type Ⅳ cancer patients was 20.1％,while it was 40.3％ for other types of cancer (P ＜ 0.05).The 5-year survival rate for Borrmann type Ⅳ gastric cancer and the other type gastric cancer was 50.0％ and 72.0％ at stage Ⅰ,30.0％ and 57.9％ at stage Ⅱ,18.0％ and 28.4％ at stage Ⅲ,and 16.4％ and 20.0％ at stage Ⅳ (all P ＜ 0.05),respectively.Multivariate analyses revealed age,histology differentiation type,tumor size,the Borrmann type carcinoma and tumor stage to be independent prognostic factors for survival.Conclusions Borrmann type carcinoma has unique clinicopathological features compared with other types of gastric carcinoma and is an important independent prognostic factor.

Objective To evaluate negative lymph node count (NLNC) in prediction of prognosis of T3 gastric cancer after radical resection.Method 214 T3 patients of radical gastrectomy with complete clinical and follow-up data between Jan 2003 to Dec 2007 were enrolled.Survival was determined by the Kaplan-Metier method and univariate analysis was done by Log-rank test,Multivariate analysis was performed using the COX proportional hazard regression model.-2loglikelihood value and the hazard ratio (HR) value were used to compared the value of number of lymph node-negative (NLNC) staging and pN staging and lymph node metastasis rate (MLR) in gastric cancer prognosis evaluation.Results Univariate analysis showed that,pN stage (x2 =31.664),MLR stage (x2 =34.123),tumor size (x2 =5.025),type of differentiation (x2 =5.993),Borrmann classification (x2 =5.401),NLNC stage (x2 =37.256) were related to survival (P ＜ 0.05).COX multivariate analysis showed that-2loglikelihood of pN staging is 1 336.761,HR value is 1.464,-2loglikelihood value of MRL staging is 1 335.821,HR value is 1.441.-2loglikelihood value of NLNC staging is 1 326.902,HR value is 1.725.The N0 and N1 staging prognosis in different NLNC staging was significant (P =0.008,P =0.014).Conclusions Sufficient number of negative lymph node prolongs survival and reduces the risk of early recurrence in advanced gastric cancer.

V infection group than in no infection group,while positive rate of other autoantibodies was not statistically different between the two groups.Conclusion Renal EBV infection may involve in the pathogenesis of LN by inducing the production of anti-Sm-Ab.

Objective To explore the reaction time and attention bias characteristics of patients with first-episode depressive disorder.MethodsTotally 32 patients with first-episode depressive disorder (MD group) and 24 non-depression control participants(NC group) matched with MD group on age,gender and education level were enrolled in the study.The clinical symptoms were assessed by Beck Depression Inventory(BDI).All participants completed a dot-probe task to assess attentional preference for facial stimuli with varying valence (happy,sad and neutral facial expressions).ResultsThe reaction times(RTs) of MD group was longer than that of NC group in the dot-probe task ((468.6±87.7)ms,(451.7±82.5)ms,P<0.01).The four-way ANOVA revealed a significant main effect of prime duration,indicating overall shorter RTs on primes with longer duration ((476.9±88.4)ms vs (456.2±82.7)ms vs (447.7±83.9)ms,P<0.01).Compared with NC group,the scores of attention bias for sad faces were decreased in MD group ((7.43±26.4)ms vs (-4.97±19.5)ms,P<0.05).With the longer duration of presentation,the score of attention maintenance of emotional facies for MD group were increased (happy faces: (-11.0±4.8)ms,(2.2±6.9)ms,(6.1±8.5)ms;angry faces:(-1.6±7.5)ms,(6.5±8.6)ms,(14.9±6.7)ms).The adherence score of attention to happy faces were decreased ((1.8±5.6)ms,(-8.2±6.7)ms,(-8.7±7.1)ms),while the score of adherence score towards sad faces were increased ((-7.6±7.2)ms,(-2.6±8.5)ms,(1.5±6.2)ms) with increasing prime duration.ConclusionPatients with first-episode depressive disorder have slower response to emotional faces and associated with attentional bias for sad faces.With the increasing prime duration,it is more and more obvious to attentional bias in the two aspects of allocation and adherence.

Objective To compare with the effect of high-frequency repetitive transcranial magnetic stimulation (rTMS) between the left and the right prefrontal on refractory negative symptoms and serum brain-derived neurotrophic factor (BDNF). Methods 80 hospitalized schizophrenics with refractory negative symptoms were divided into study group (n=40) and control group (n=40) randomly. Both groups were received 4-week treatment of 10 Hz rTMS. The stimulus lo?cation of the study group was the left prefrontal, and the control group was the right prefrontal. The type and dose of anti?psychotics remained unchanged during the treatment. The evaluation of positive and negative symptom scale (PANSS) and the measurement of BDNF concentration before treatment and after 4 weeks treatment was analyzed. Results Com?pared with before treatment, the total score of PANSS after treatment significantly decreased (P<0.05) both in the study group [(71.2±13.8) vs. (63.3±11.4)] and the control group [(70.3±13.4) vs. (63.7±12.2)]. The score of negative symptoms in the study group decreased [(22.8±6.6) vs. (18.4±5.9), P<0.01]. The BDNF concentration increased in the study group ](6.78±2.16) vs. (8.74±2.76)] and the control group [(6.83±2.32) vs. (8.66±2.70)]. Conclusion 10Hz rTMS on the left pre?frontal combined with drugs are helpful to improve the refractory negative symptom of the patients with schizophrenia. Stimulation on both left and right prefrontal lobe could increase serum BDNF concentration.

Objective To explore the influence factors of hyperarousal,personality characteristics and coping strategies on the vulnerability to stress-related sleep disturbance.Methods A total of 345 sleep good healthy volunteers were recruited bypurposive sampling technique.Every participant completed an extensive survey that included the general condition questionnaire,Ford Insomnia Response to Stress Test (FIRST),PreSleep Arousal Scale (PSAS),NEO Personality Inventory-Revised (NEOPI-R),Coping Inventory for Stressful Situations (CISS) and Heart Rate Variability(HRV).All participants were classified as High risk group andLow risk group by using the FIRST criterion.Results The high risk group was younger than the low risk group (27.91±8.22 vs 24.82±7.73,P＜0.01),and had a higher percentage of females (34.7％ vs 53.4％,P＜0.05).The high risk group showed significantly higher scores in PSAS total (30.11±6.22),pesleep cognitive arousal (17.73± 4.51),presleep somatic arousal (12.78 ± 3.23),neuroticism (3.13 ± 0.51),emotion oriented (48.98 ± 10.54),but lower score in extraversion (2.96±0.54),then those indicators of the low risk group (28.52±5.82,16.32±4.32,11.41±2.75; 3.11±0.56,2.87±0.47,46.23±11.21,3.11±0.56,P＜0.01 or 0.05).There were significant difference between the two group in LF/HF (1.51 ±0.19 vs 1.17±0.11,P＜0.01),HF((311.21 ±72.32) ms2/Hz vs (490.43 ± 91.74)ms2/Hz,P＜0.01),LF((469.49±85.67)ms2/Hzvs (573.21±98.75) ms2/Hz,P＜0.01) in HRV.Results of linear regression analysis showed that gender,and scores of PSAS total,cognitive arousal,presleep cognitive arousal,presleep somatic arousal,neuroticism,emotion oriented and LF/HF were significant correlation with FIRST score (P＜0.01 or 0.05).Conclusion Presleep cognitive and somatic arousal,neurotic character may be the premorbid characteristics of stress-related sleep disturbance,and bad stress coping strategies are easy to promote the development of insomnia.

Objective:To investigate the relationship between iodine nutrition level and thyroid disease.Methods:Totally 299 patients with thyroid disease who were treated at Shandong Provincial Institute for Endemic Disease Prevention and Control from 2016 to 2018 were selected as case group which was further divided into Graves' disease group (GD group, 137 patients), chronic lymphocytic thyroiditis group (HT group, 90 patients) and thyroid nodule group (72 patients). At the same time, 75 healthy people with no history of thyroid disease, normal thyroid color ultrasound and thyroid function were selected as control group. Morning urine was collected and urinary iodine was detected by arsenic cerium catalytic spectrophotometry. Fasting venous blood was extracted, and serum levels of thyroid stimulating hormone (TSH), free triiodothyronine (FT 3), free thyroxine (FT 4), thyroid globulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb) were detected by electrochemiluminescence method. Results:The difference of median urinary iodine in the 4 groups was statistically significant ( H = 42.530, P < 0.05). The medians urinary iodine in GD and HT groups (326.79, 341.91 μg/L) were higher than those of thyroid nodule group and control group (235.01, 187.32 μg/L, P < 0.05). The levels of TSH, FT 3 and FT 4 in GD group were compared with those of control group, and the differences were statistically significant ( P < 0.05). The positive rates of TgAb and TPOAb in HT group were significantly higher than those in GD, thyroid nodule and control groups, and the positive rates of TgAb and TPOAb in GD group were higher than those in thyroid nodule and control groups ( P < 0.05). Conclusions:GD and HT patients have excessive iodine nutrition, and high iodine intake may lead to the occurrence of these thyroid diseases (GD and HT). Thyroid function test combined with laboratory urinary iodine test can be used to diagnose thyroid diseases simply and quickly.

ABSTRACT:To improve the ability of correct classification and identification of rodents in different kinds of foci of zoonosis in Ningxia Hui Autonomous Region in China ,rodents samples from different habitats of Ningxia were collected .Sequences of COI gene were amplified and sequenced from 154 samples .Based on these sequences ,the pairwise genetic distance were calcu‐lated ,and a Neighbor Joining tree were constructed .According to the NJ tree ,20 clusters with high bootstrap support were found from 19 morphological species .The striped dwarf hamsters were divided into two clusters ,which suggested that there were two cryptic species with stripe on the back .The pika from Helan Mountain showed close relationship with Ochotona pal‐lasi ,and the genetic distance was as low as 3 .6% .Results show that DNA barcodes could be used to accurately identify speci‐mens of rodents and correct morphological identification errors .It could discover appearance indistinguishable implied species and could better study the classification and evolution of rodents .
