Objective:To investigate the expression of serum microRNA (miR)-92 in patients with liver cancer and its relationship with poor prognosis.Methods:The clinical data of 70 patients with liver cancer in the First People′s Hospital of Huzhou City, Zhejiang Province and the Central Hospital of Huzhou City, Zhejiang Province from May 2015 to May 2018 were retrospectively analyzed. The miR-92 expression level was detected by real-time quantitative polymerase chain reaction method and compared with that of 80 healthy subjects. Receiver operating characteristic (ROC) curve was drawn to evaluate the efficacy of serum miR-92 in diagnosing liver cancer and early stage (stage Ⅰ to Ⅱ) liver cancer. The relationship between serum miR-92 expression level and clinicopathological characteristic was analyzed. Independent risk factors affecting the prognosis in patients with liver cancer were analyzed by multivariate Cox regression model.Results:The expression level of serum miR-92 in patients with liver cancer was significantly higher than that in healthy subjects (4.10 ± 1.74 vs 1.88 ± 0.78), and there was statistical difference ( P<0.05). ROC curve analysis result showed that the area under curve (AUC) of serum miR-92 for the diagnosis liver cancer was 0.874, the best cut-off value was 2.43, the sensitivity was82.86%, and the specificity was 86.25%; the AUC of serum miR-92 for the diagnosis early liver cancer was 0.755, the best cutoff value was 2.38, the sensitivity was 68.57%, and the specificity was 84.42%. The serum miR-92 expression level was related to TNM stage and lymph node metastasis ( P<0.01), but not related to gender, age, tumor diameter, history of hepatitis, liver cirrhosis, degree of differentiation and portal vein tumor thrombus ( P>0.05). The 5-year overall survival rate in liver cancer patients with high serum miR-92 expression was significantly lower than that in liver cancer patients with low serum miR-92 expression (17.1% vs. 31.5%), and there was statistical difference ( χ2 = 5.561, P<0.05). Multivariate Cox regression analysis result showed that miR-92 was an independent risk factor affecting the prognosis in patients with liver cancer ( HR = 0.282, 95% CI 1.179 to 3.562, P<0.05). Conclusions:The expression level of serum miR-92 in patients with liver cancer is significantly increased, which plays an important role in the progression of the disease. Serum miR-92 can be used as an indicator for early diagnosis and prognosis evaluation of liver cancer.

Objective To explore the neuropsychological features of cognitive impairment induced by chemotherapy for breast cancer patients.Methods A neuropsychology battery was applied in this study.Seventy six breast cancer patients were enrolled in the test and classified as chemotherapy treatment patients(CT,n =38),and non-chemotherapy treatment patients(non-CT,n =38).Forty normal female people were also evaluated as healthy control(HC).Results Compared with HC and non-CT groups,the correct number of backward(CT:4.42±1.11,non-CT:5.18 ± 1.16,HC:5.13 ± 1.22),delayed recall (CT:8.55 ± 1.75,non-CT:9.58 ± 1.50,HC:10.13 ± 1.92) and recognition (CT:7.68 ± 1.90,non-CT:8.97 ± 1.62,HC:9.08 ± 2.09) were low in the CT group (P ＜ 0.01).The reaction time of Stroop test B (CT:(21.54 ± 5.02) s,non-CT:(19.37 ± 4.26) s,HC:(18.82 ± 3.05) s),Stroop test C (CT:(34.85 ± 8.46) s,non-CT:(31.02 ± 7.38) s,HC:(30.61 ± 7.83) s) and TMT test B(CT:(102.79± 11.90)s,non-CT:(96.22 ± 12.07) s,HC:(97.21 ± 11.64)s) were long in the CT group (P ＜ 0.05).There were no significant differences in the Forward,Immediate Recall,Stroop test A,TMT test A and VFT among three groups(P＞ 0.05).Conclusion Breast cancer patients with chemotherapy treatment have cognitive impairment in the domains of memory,attention and executive functions.

To evaluate the status of diabetes-related knowledge and training requirement among general physicians,a questionnaire survey was conducted in 676 general physicians from 32 primary medical institutions and 5 secondary hospitals of Shanghai Pudong New Area.48.2% (261/541) of the surveyees had bachelor degree and most of them worked in secondary hospitals or primary medical institutions in affluent areas.The awareness rate of diabetic knowledge among the surveyeos was 51.6%,and there were significant differences in the awareness rate of diabetes-related knowledge between different levels of hospitals and physicians with different academic background.Only 26.6% of physicians received diabetes-related continuing education or training,there was a popular request for professional training from the surveyed physicians.

Objective To investigate the therapeutic effects of nano-hydroxyapatite/polyamide 66/platelet-rich plasma com-pound(n-HA/PA66/PRP)on the recovery of rabbit femur bone defect.Methods 40 New Zealand rabbits were artificially made to be bone defect by resecting the 1 cm substantia ossea with periosteum of femur,and were divided into two groups averagely depen-ding on implanted materials:experimental group(n-HA/PA66/PRP),control group (n-HA/PA66).Every five rabbits were sacri-ficed on week 2,4,8,12,and the femur healing status was observed by X ray,histology,and immunohistochemistry.Results No rabbit was infected or died,no implantation objects dropped.Gross observation,X-ray result and histology results demonstrated that the experimental group began to have a new bone tissue at 2 weeks after the operation,with the extension of time,the experimental group new bone growth speed and the quantity was better than the control group.The Lane-Sandhu method X-ray score showed that the experimental group (6.80±2.05)points and the control group(4.20±1.30)points at 12 weeks after the operation,and there were significant differences between two groups(P <0.05).Immunohistochemistry indicated that expression intensity of Vas-cular endothelial growth factor at 2 weeks and 4 weeks were significant differences between two groups(P <0.05),but there was no significant difference at 8 weeks and 12 weeks (P >0.05).Conclusion PRP combined with n-HA/PA66 artificial bone could accel-erate the healing of bone defect,and the effect of repair of bone defect is better than that of n-HA/PA66 artificial bone in the early.

Objective To investigate the correlation between the serum ferritin levels and the post-stroke depression (PSD). Methods From July 2014 to October 2015, the inpatients with the first-ever acute ischemic stroke were colected consecutively. Chemiluminescence microparticle immune assay was used to measure the serum ferritin levels within 24 h after admission. Depressive symptoms were screened by using the 17-item Hamilton depression scale (HAMD-17) at 3 months after onset. In patients with a HAMD-17 score ≥7, the depression was further diagnosed according to The Diagnostic and Statistical Manual of Mental Disorders, 4th edition. Results A total of 200 patients with the first-ever acute ischemic stroke were enroled, 55 (27. 5% ) of them were diagnosed as PSD. There were significant differences in the body mass index (BMI), years of education, waist circumference, high sensitive-C-reactive protein, homocysteine, National Institutes of Health Stroke Scale score (at baseline, discharge, and day 90), mRs score (at discharge and day 90), BI (at discharge and day 90), and the proportions of widowed or solitary patients between the PSD group and the non-PSD group (al P < 0. 05 ). The serum ferritin level in the PSD group was significantly higher than that in the non-PSD group ( median [ interquartile range], 261. 90[142. 10-364. 90] μg/L vs. 164. 40[132. 50- 195. 10] μg/L; Z = - 4. 814, P < 0. 001 ). Multivariate logistic regression analysis adjusted for confounding factors showed that the baseline serum ferritin level >136. 375 μg/L was an independent risk factor for PSD (odds ratio 1. 041 per 1-quartile increase, 95%confidence interval 1. 009-1. 239; P = 0. 045). Conclusions The elevated baseline serum ferritin level is associated with PSD.
