Objective To explore the relation between plasmocytoid dentritic cells (pDCs) and cerebral immune-inflammation reaction following ischemic stroke. Methods Circulating pDCs were measured by flow cytometry in 62 patients with acute ischaemic stroke (AIS), 26 healthy controls, 12 patients with asymptomatic cerebral infarction stenosis (ACI-S), and 14 patients with transient ischaemic attack (TIA). The sizes of infarct lesions were assessed by DWI scanning. AIS group was further divided into lacunar infarction group, small infarction group,and large infarction group according to the infarction area. The correlation between the number of pDCs and NHISS score and CRP level was also analyzed in AIS group. Results The labsolute number of pDCs and the percentage of pDCPs to circulating blood white cells were significantly lower in AIS group than in the healthy control group (P<0.001). As compared with lacunar infarction group, the number of pDCPs decreased significantly in large infarction group. The number of pDCPs was negatively correlated with the levels of CRP and the NIHSS score. Conclutions Patients with AIS has a decreased level of circulating pDCs, which may be involved in the gathering of circulating pDCs in the infarcted brain to trigger cerebral immune reaction.

Objective To explore the association of NH2-terminal pro-B-type natriuretic peptide ( NT-proBNP) with the risk of type 2 diabetes.Methods One hundred and twenty-six impaired glucose regulation( IGR) participants from Diabetic Identification Center of Tianjin Metabolic Diseases Hospital were included.NT-proBNP was measured in plasma samples collected from participants at baseline condition.Results At baseline, NT-proBNP was inversely associated with body mass index, waist circumference, fasting glucose, insulin and low-density lipoprotein-cholesterol( LDL-C) levels.During a follow-up of 2 years, 51 participants reported a new diagnosis of diabetes from OGTT.Baseline quartiles of NT-proBNP were inversely associated with diabetes risk, even after multivariable adjustment.Theadjustedrelativerisksfordiabeteswere1.0(reference),0.83(95%CI0.74-0.96),0.78(95%CI 0.68-0.90), 0.74 (95%CI 0.64-0.87) for the 1st, 2nd, 3rd, and 4th quartiles of baseline NT-proBNP, respectively ( P<0.01 ) .Conclus ion In IGRpopulation , lowlevels of NT-proBNP were associated with a significantly increased risk of type 2 diabetes.

Objective Discussion the relationship of PALB2 and AR expression in triple negative breast cancer and its clinical pathological features. Methods The SP immunohistochemical staining was adopted to detect the expression of PALB2 and AR in 178 cases of TNBC, PALB2 divided into two groups according to the expression of different, and to analyze the clinical pathological features and prognostic impact of different AR expression status. Results 178 cases of TNBC, that PALB2 missing expression 47 cases (26.4%), AR expression of 60 cases (33.7%), between of them were negatively correlated (-1≤r<1, P<0.05), in PALB2 negative group, AR expression associated with family history, lymph node metastasis, clinical stage and recurrence and metastasis (P<0.05), and 5-year disease-free survival lower than AR negative expression, Log rank = 4.453, P = 0.035. Conclusion PALB2 negative expression while AR positive expression in TNBC have synergistic effect with disease progression, PALB 2 and AR combined detection may provide a new basis for the prognosis of TNBC interpretation, and recommending take further studies to confirm.

Objective To investigate the clinical significance of BRCA1/ 2 mutation in breast cancer patients with different malignant tumor family history. Methods We studied 98 cases of diagnosed breast cancer patients with malignant tumor family history. BRCA1/2 screening was performed by PCR-DHPLC sequencing method. All mutations were confirmed by using direct DNA sequencing. Results The prevalence of BRCA1/2 germline mutation was 20.41%.The BRCA1/2 mutation was 55.6% in patients with family breast and ovarian cancer, and was 20.0% and 17.9% in patients with family breast and in patients with ovarian cancer, respectively. In correspondence to 2 and 3 and 4 people withof the breast or ovarian cancer in family , the BRCA1/2 mutation was 16.25%、33.3%、66.67% ,respectively. Conclusion The BRCA1/2 mutation rate increased in the patients with breast and ovarian cancer family history, and the detection of BRCA1/2 mutation increased with the number of patients with cancer in a family.

Background and purpose:Triple-negative breast cancer (TNBC) is currently the focus of breast cancer research. Researches demonstrated that the molecular biological characteristics of different ethnic groups are not the same. This study mainly probed into the expression of endothelial growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) in Han and Uygur TNBC patients, and the relationship between the expression and prognosis of patients.Methods:From Jan. 2007 to Jan. 2009, 167 patients were admitted. Among those, 121 were Han and 46 were Uygur patients. The expressions of EGFR, and VEGF were detected by PV-9000 immunohistochemical staining, and compared with lymph node metastasis and clinical staging. The results were analyzed by SPSS 18.0 statistical software.Results:Five-year disease-free survival (DFS) of two groups had no indifferent (P>0.05). EGFR and VEGF positive rate of Han patients was lower than that of Uygur patients (P<0.05). Their expressions were correlated with TNM staging and lymph node metastasis (00.05). Uygur TNBC patients might have a different prognostic factor as compared with Han patients. Further studies need to be carried out.

Objective To investigate the effects of environmental hypothermia on hemodynamics and oxygen metabolism in unanesthetized swine model of hemorrhagic shock.Methods A total of 16 Bama pigs provided by animal experiment centre of the General Hospital of Shenyang Military Command were randomized into two groups ( n =8,each):ambient temperature (A) and hypothermia ( H ).Venous blood (30 mL/kg) was continously withdrawn over 15 minutes to establish hemorrhagic shock model.Core temperature,heart rate,mean arterial pressure,central venous pressure,cardiac output,saturation of mixed venous blood and blood gas analysis were recorded at the baseline and different hemorrhagic shock time.DO2I and VO2I,and the O2 extraction ratio (O2ER) were calculated.Results Core body temperature in group A decreased slightly after hemorrhagic shock model had established and environmental hypothermia resulted in more reduction in core body temperature.The mortality rate was significantly higher in group H (50％) than in group A (0％) (P ＜0.05).DO2I and VO2I decreased significantly after hemorrhage.No difference was found in hemodynamics,DO2I and VO2I between group A and group H,but the difference of pH,lactic acid and O2ER were significant between the two groups (P ＜ 0.05 ).conclusions Environmental hypothermia aggravated the disorder of oxygen metabolism after hemorrhagic shock,which was associated with poor prognosis.

OBJECTIVE:To systematically evaluate therapeutic efficacy of modified Shenqi dihuang decoction in the treatment of chronic glomerular nephritis. METHODS:Retrieved from Wanfang database,CNKI,VIP,CBM,Cochrane Library,Medline, EMBase and PubMed,randomized controlled trials(RCTs)about modified Shenqi dihuang decoction combined with conventional therapy and (or) other Chinese patent medicine (trial group) vs. conventional therapy and (or) other Chinese patent medicine (control group)in the treatment of chronic glomerular nephritis were collected. Meta-analysis was carried out by using Rev Man 5.3 software after literature scanning,data extraction and quality evaluation. Stata 14.0 software was used to conduct Egger test to evaluate publication bias. If publication bias existed,the effect of publication bias on outcome was further evaluated by scissor compensation. TSA v0.9 software was used for trial sequential analysis(TSA)of total efficency. RESULTS:A total of 10 RCTs were included,involving 707 patients. The results of Meta-analysis showed that total response rate of trial group [RR＝1.40,95%CI(1.22, 1.61),P＜0.001] was significantly higher than that of control group; the level of urine protein [SMD＝－1.97,95%CI(－2.92,－1.03),P＜0.001] and Scr [MD＝－28.41,95%CI(－38.95,－17.87),P＜0.001] in trial group were significantly lower than control group,with statistical significance. Publication bias test of total response rate was conducted,and results of it showed that there was publication bias,but bias did not affect the results of this study. TSA analysis showed that the evidence of Meta-analysis was false positive. CONCLUSIONS:Therapeutic efficacy of modified Shenqi dihuang decoction for chronic glomerular nephritis need to be proved by more stringent RCTs.

OBJECTIVE: To establish a rat model of cervical syndrome (CS) with kidney deficiency. METHODS: A group of 30 three-month-old female Sprague-Dawley rats were randomly divided into normal control group, CS group and CS with kidney deficiency group (combined group), with 10 rats in each group. Rats in the normal control group received no treatment, rats in the CS group underwent only resection of cervical muscles and ligaments as unbalanced dynamic and static animal model, and rats in combined group underwent resection of both cervical muscles and ovaries as kidney deficiency model. Serum and cervical intervertebral discs were collected. Kidney deficiency was determined by observing the morphologic changes of uterus and appendages, detecting the weight of uterus and appendages and the content of serum estradiol (E(2)). The degeneration of intervertebral discs was determined by detecting the histopathology, the expressions of type II collagen and type X collagen proteins, and the expressions of aggrecan-1 (Agc1), type II procollagen gene (Col2a1), matrix metalloproteinase-13 (MMP-13) and tissue inhibitor of metalloproteinases-1 (TIMP-1) mRNAs. RESULTS: Compared with those in the normal control group and CS group, the rats in the combined group were noted with the uterus atrophied, the caliber of oviduct thinned, the weight of uterus and appendages diminished obviously, the content of serum E(2) decreased, cervical intervertebral disc degenerated more seriously, type II collagen protein expression decreased, type X collagen protein expression increased, Agc1 and Col2a1 mRNA expressions in intervertebral disc decreased, and the MMP-13 mRNA expression increased. CONCLUSION: The rat model of CS with kidney deficiency is established. Kidney deficiency can aggravate cervical intervertebral disc degeneration.
