Relationship between serum Lp-PLA2, PARK7, EPO levels and NIHSS scores and CIMT in patients with acute ischemic stroke / 中国医师杂志

Objective:To investigate the relationship between the changes of serum lipoprotein associated phospholipase A2 (Lp-PLA2), human Parkinson′s protein 7 (PARK7), erythropoietin (EPO) and neurological deficit score (NIHSS) and carotid intima-media thickness (CIMT) in patients with acute ischemic stroke (AIS).Methods:150 patients with AIS diagnosed in our hospital from January 2016 to January 2018 (AIS group) and 80 healthy subjects were selected as the control group. The Lp-PLA2, PARK7, EPO levels were compared between the two groups according to NIHSS score (mild, moderate and severe), carotid atherosclerotic plaque (unstable plaque, stable plaque, no plaque).Results:The serum level of Lp-PLA2, PARK7, EPO and CIMT values in the AIS group were significantly higher than those in the control group ( P<0.05). The Lp-PLA2 and PARK7 levels in the mild, moderate and severe AIS patients were gradually increased among the three groups, with statistically significant difference ( P<0.05). There was no significant difference in EPO levels between the different NIHSS groups ( P>0.05); The levels of Lp-PLA2, PARK7 and EPO of AIS patients in non plaque group, stable plaque group and unstable plaque group were gradually increased among the groups, and the difference between the two groups was statistically significant ( P<0.05). The level of Lp-PLA2 and PARK7 in patients with AIS and the NIHSS scores showed a significant positive correlation ( P<0.05). There was a significant positive correlation between Lp-PLA2, PARK7, EPO and CIMT in patients with AIS ( P<0.05). Conclusions:The serum levels of Lp-PLA2, PARK7 and EPO were significantly increased in AIS patients. Lp-PLA2, PARK7 were related to the aggravation of neurological deficits in potential patients. Lp-PLA2, PARK7 and EPO were related to the increase of carotid intima-media thickness in potential patients.

Prognostic evaluation of patients with TNM stage Ⅰ to Ⅲ gastric cancer by platelet-lymphocyte ratio and neutrophil-lymphocyte ratio / 中华消化杂志

Objective:To compare the ability of platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR) in evaluating the prognosis of patients with TNM stageⅠto Ⅲ gastric cancer.Methods:From May 2001 to December 2013, the clinicopathological data of 645 patients with gastric cancer treated at Harbin Medical University Cancer Hospital were retrospectively analyzed. Chi-square test was used to analyze the differences between NLR, and PLR and clinicopathological characteristics of patients. Kaplan-Meier method and log-rank test were performed to compare the overall survival of patients. Cox proportional hazards regression model was performed to analyze the prognosis of gastric cancer patients. The ability of NLR and PLR to evaluate the prognosis of gastric cancer was compared by receiver operating characteristic curve.Results:The cutoff values of PLR and NLR were 141.50 and 1.94, respectively. PLR was associated with gender, resection method, maximum diameter of tumor, whether chemotherapy, T-stage, N-stage, TNM stage, tumor location, white blood cell, hemoglobin, albumin, and whether total gastrectomy ( χ2=9.224, 10.577, 28.825, 6.831, 29.059, 28.637, 30.748, 18.023, 24.320, 77.274, 9.021 and 10.745, all P<0.05). NLR were associated with resection method, maximum diameter of tumor, T-stage, N-stage and TNM stage, white blood cell, hemoglobin and albumin ( χ2=14.563, 12.092, 22.697, 44.735, 34.151, 7.949, 9.611 and 7.498, all P<0.05). The results of multivariate analysis showed that resection method, whether chemotherapy, T-stage, N-stage, PLR and whether total gastrectomy were all independent risk factors for gastric cancer patients ( χ2=23.653, 22.023, 16.697, 24.038, 4.110 and 22.364, all P<0.05). The five-year cumulative survival rate of the patients with PLR<141.50 was higher than that of patients with PLR≥141.50 (55.4% vs. 30.5%), and the difference was statistically significant ( χ2=47.968, P<0.01). The AUC value of PLR in prognostic evaluation of gastric cancer was 0.629, which was higher than that of NLR (0.596, P<0.01). Conclusion:PLR is better than NLR in the prognostic evaluation of gastric cancer patients.

The prognostic value of serum albumin and hemoglobin in patients with proximal gastric cancer / 中华普通外科杂志

Objective To evaluate serum albumin (ALB) combined with hemoglobin (Hb) (ALB-Hb) in the prediction of prognosis of patients with proximal gastric cancer.Methods Clinial data of 311 patients with stage Ⅰ-Ⅲ proximal gastric cancer who underwent radical surgery were retrospectively analyzed in Harbin Medical University Cancer Hospital from Sep 2001 to Nov 2014.The preoperative ALB-Hb was calculated as following:patients with both elevated serum albumin (≥40.25 g/L) and hemoglobin (≥120 in male or ≥110 g/L infemale) were given a score of 0,and patients with only one or none were given a score of 1 or2,respectively.The ALB-HB scores of 0 points had 175 cases (56.2％),1 point had 87 cases (28.0％),and 2 points had 49 cases (15.8％).The optimal cut-off value of serum albumin,platelet count and maximum tumor diameter were defined by ROC curve;Pearson correlation was used to evaluate the correlation coefficient between serum albumin and HB;Survival analysis was analyzed by Kaplan-Meier method.The prognostic factors for patients with proximal gastric cancer was analyzed by COX proportional hazards model.The ROC curve was used to compare the prognostic value of serum albumin,hemoglobin,and ALB-Hb.Results Patients with ALB-Hb score of 2 were associated with age,serum platelet level,and maximum tumor diameter (all P ＜ 0.05).The median survival time was 41 months (3-134 months).233 cases (74.9％) died and 78 cases (25.1％) survived as of Jan 2018.There was a significant difference in overall survival (OS) among A1B-Hb scores of 0,1,and 2 (P =0.011).Univariate analysis demonstrated that platelet count,ALB-Hb score,maximum tumor diameter,and clinical stage were related to the prognosis of patients with proximal gastric cancer (all P ＜ 0.05).By multivariate analysis there were statistically significant differences in pathological parameters:ALB-Hb score (HR =1.249,95％ CI 1.047-1.489,P =0.013),maximum tumor diameter (HR =1.352,95％ CI 1.016-1.799,P=0.038) and TNM clinical stage (HR=1.667 95％ CI 1.266-2.194,P＜0.001) is an independent risk factor for prognosis.ALB-Hb score compared to serum albumin and hemoglobin alone,has a higher AUC value (P =0.019).Conclusions The preoperative ALB-Hb score is superior to serum albumin or hemoglobin alone in assessing the prognosis for patients with stage Ⅰ,Ⅱ,and Ⅲ proximal gastric cancer.

Comparison of clinicopathological features and prognosis between adenocarcinoma of esophagogastric junction and adenocarcinoma of gastric antrum / 中华胃肠外科杂志

OBJECTIVE@#To compare the clinicopathological features and the prognosis between patients with adenocarcinoma of esophagogastric junction (AEG) and with adenocarcinoma of gastric antrum (AGA), and to investigate the prognostic factors of AEG and AGA.@*METHODS@#A retrospective cohort study was performed on clinicopathological data of 239 AEG patients (AEG group) and 313 AGA patients selected simultaneously (AGA group) undergoing operation at Harbin Medical University Cancer Hospital from January 2001 to December 2012.@*INCLUSION CRITERIA@#(1) receiving radical surgery (R0 resection); (2) AEG or AGA confirmed by pathological examination of postoperative tissue specimens; (3) without preoperative neoadjuvant radiotherapy or chemotherapy; (4) complete clinicopathological and follow-up data; (5) patients who died of non-tumor-related causes were excluded. Chi-square test and independent samples t-test were used to determine differences in clinicopathological factors between two groups. The overall survival (OS) of patients was compared by Kaplan-Meier method and Log-rank test. Multivariate prognosis analysis was performed using Cox proportional hazards regression model.@*RESULTS@#As compared to AGA group, AEG group had higher proportion of male [82.0%(196/239) vs. 65.2%(204/313),χ²=19.243,P0.05). The 5-year OS rate was 33.5% and 56.9% in AEG group and AGA group respectively and the median OS was 60.0(3.0-60.0) months and 33.6(3.0-60.0) months respectively; the difference was statistically significant (P<0.001). In AEG group, univariate analysis showed that differences of hemoglobin level (5-year OS rate: 24.0% for <130 g/L, 39.9% for ≥130 g/L, P=0.006), tumor diameter (5-year OS rate: 41.9% for <5 cm,28.8% for ≥5 cm, P=0.014), N stage (5-year OS rate: 42.2% for N0, 40.9% for N1, 31.7% for N2, 15.8% for N3a, 9.0% for N3b, P<0.001) and TNM stage (5-year OS rate: 56.2% for stage I, 38.5% for stage II, 28.3% for stage III,P=0.017) were statistically significant (all P<0.05); multivariate analysis revealed that the worse N stage was an independent risk factor of prognosis survival for AEG patients(HR=1.404,95%CI:1.164-1.693, P<0.001), and serum hemoglobin level ≥130 g/L was an independent protective factor of prognosis survival for AEG patients (HR=0.689,95%CI:0.501-0.946,P=0.021). In AGA group, univariate analysis showed that differences of serum albumin (5-year OS rate: 49.1% for <40 g/L, 61.1% for ≥ 40 g/L, P=0.021), tumor diameter (5-year OS rate: 74.2% for <5 cm, 39.9% for ≥ 5 cm, P<0.001), T stage (5-year OS rate: 98.3% for T1,83.3% for T2,50.0% for T3,36.8% for T4, P<0.001), N stage (5-year OS rate: 89.0% for N0, 62.3% for N1, 50.0% for N2, 33.9% for N3a, 10.3% for N3b, P<0.001) and TNM stage (5-year OS rate: 97.3% for stage I, 75.8% for stage II, 32.8% for stage III, P<0.001) were statistically significant (all P<0.05); multivariate analysis revealed that the worse T stage (HR=1.516,95%CI:1.060-2.167,P=0.023) and the worse N stage (HR=1.453,95%CI:1.209-1.747,P<0.001) were independent risk factors for prognosis of AGA patients.@*CONCLUSIONS@#As compared to AGA, AEG presents have poorer prognosis,and is easier to present with later pathological stage and larger tumor diameter. N stage and hemoglobin level are independent factors associated with the OS of AEG patients. T stage and N stage are independent factors associated with the OS of AGA patients.

Dose analysis of hippocampus in T3,T4nasopharyngeal carcinoma patients treated with intensity modulated radiotherapy / 中华放射肿瘤学杂志

Objective To analyze the exposed dose of hippocampus(HC)of T3,T4nasopharyngeal carcinoma patients treated with intensity modulated radiotherapy(IMRT). Methods The bilateral HCs were delineated and were divided into head(HH),body(HB)and tail(HT)for 62 nasopharyngeal carcinoma patients treated with IMRT.The dose parameters of HC were then analyzed. Results The mean dose of left and right HC was(1 127±704)cGy,(1 173±762)cGy. The mean dose of left HH,HB and HT was(1 732±1029)cGy,(820±632)cGy,(423±366)cGy(P=0.000);while the mean dose of right HH, HB and HT was(1 985±1101)cGy,(837±531)cGy,(432±343)cGy(P=0.000).The exposed dose and the volume exposed in different dose of HH were obviously higher than those of HB and HT.The dose parameters of HH,HB and HT decreased in turn. The involvement of sphenoid sinus,ethmoid sinus and cavernous sinus correlated with high exposed dose of HC. Conclusions The exposed dose of HH,HB and HT was different in nasopharyngeal carcinoma patients treated with IMRT.The exposed dose of HH was the highest,which should be emphasized especially. The involvement of sphenoid sinus,ethmoid sinus and cavernous sinus suggest high exposed dose of HC.

The clinical value of prognostic nutritional index in gastric cancer patients with peritoneal metastasis / 中华普通外科杂志

Objective To evaluate the prognostic value of prognostic nutritional index (PNI) in gastric cancer patients with peritoneal metastasis.Methods 287 gastric cancer patients with peritoneal metastasis were enrolled from Jan 2010 to Dec 2016.Results Compared with PNI ＞ 45,patients in PNI≤45 group were elder [(59 ± 11) vs.(54 ± 11),t =3.734,P =0.000],lower albumin [(35 ± 4) g/L vs.(42 ± 4)g/L,t =15.988,P =0.003)],lower plasm hemoglobin concentration [(110 ± 22)g/L vs.(129 ±24) g/L,t =6.245,P =0.000),higher platelet count/lymphocyte count ratio [PLR,(210 ± 89) vs.(150 ± 66),t =6.547,P =0.000],higher neutrophil count/lymphocyte count ratio [NLR,(3.7 ± 2.9)vs.(2.4 ± 1.2),t =4.628,P =0.000],lower percentage of pallative gastrectomy (45.5％ to 58.5％,x2 =4.45,P =0.035).Logistic regression analysis showed that age ＞ 58-years,NLR ＞ 2.87,PLR ＞ 170,hemoglobin ≤ 130 g/L,local organ infiltration were risk factors leading to low-PNI (all P ＜ 0.05).The median survival time for all patients was 8.7 months.Univariate analysis revealed that,PNI ＞ 45,serum albumin ＞ 40 g/L,no ascites,lower-grade of peritoneal metastasis,pallative gastrectomy,postoperation chemotherapy were positively associated with better prognosis (all P ＜ 0.05).Multivariate analysis demonstarted that,PNI (HR =0.717,P =0.039).Grade of peritoneal metastasis (HR =1.206,P =0.044),pallative gastrectomy (HR =1.529,P =0.001) were independent prognostic risk factors for the patients with peritoneal metastasis.Conclusion PNI are both predictors of nutrition assessment and of prognosis for gastric cancer patients with peritoneal metastasis.

Effects of glycyrrhetinic acid on proliferation and apoptosis of, as well as miR-21 expression in keratinocytes from patients with psoriasis / 中华皮肤科杂志

Objective To preliminarily evaluate the effect of glycyrrhetinic acid on the proliferation and apoptosis of keratinocytes in patients with psoriasis,and to explore its possible mechanisms.Methods Keratinocytes were isolated from patients with psoriasis,and subjected to a primary culture in vitro.After 2-3 passages,the keratinocytes were divided into several groups to be treated with glycyrrhetinic acid at final concentrations of 0 (control group),1,2,4,8 and 10 mg/L (glycyrrhetinic acid groups),respectively.After 24-72 hours of treatment,MTS assay was performed to evaluate the effect of glycyrrhetinic acid on the proliferation of keratinocytes,and flow cytometry was conducted to detect the apoptosis of keratinocytes after 24-hour treatment with glycyrrhetinic acid at different concentrations.Real-time fluorescence-based PCR was performed to determine the expression of miR-21 in keratinocytes.Results After 24-72 hours of treatment with 1-10 mg/L glycyrrhetinic acid,the proliferation activity of keratinocytes significantly decreased along with the increase in the treatment duration and concentrations of glycyrrhizinic acid.After 24-hour treatment with 1,2,4,8,10 mg/L glycyrrhetinic acid,the apoptosis rates of keratinocytes increased to (9.64 ± 0.86)％,(25.24 ± 2.93)％,(27.68 ± 3.70)％,(35.55 ± 4.23)％ and (38.89 ± 2.31)％ respectively.As LSD-t test showed,the apoptosis rates of keratinocytes were significantly higher in all the glycyrrhetinic acid groups than in the control group (10.09％ ± 0.69％,all P ＜ 0.01),except the 1 mg/L glycyrrhetinic acid group.After 24-hour treatment with 1,2 and 4 mg/L glycyrrhetinic acid,the miR-21 expression (2-△△Ct) significantly decreased (0.24 ± 0.04,0.22 ± 0.07,0.17 ± 0.05,respectively) compared with the control group (0.92 ± 0.12,F =213.10,P ＜ 0.05).After 18-,24-and 48-hour treatment with 2 mg/L glycyrrhetinic acid,the miR-21 expression significantly decreased (0.55 ± 0.02,0.22 ± 0.06 and 0.15 ± 0.06 respectively) compared with the control group (0.98 ± 0.02,F =238.10,P ＜ 0.05).Conclusion Glycyrrhetinic acid can inhibit the proliferation of keratinocytes from psoriatic patients,but promote the apoptosis,likely by down-regulation of miR-21 expression.
