ABSTRACT

Objective:Based on the occupational cohort of Beijing Medical Examination Center, to explored the relevant factors of nonalcoholic fatty liver disease (NAFLD), and to provide scientific basis for screening and early diagnosis of NAFLD in high-risk population.Methods:Based on the cohort of occupational population who underwent physical examination in Beijing physical examination center from January to December 2009, the physical examination indexes were collected, and a retrospective survival cohort with a follow-up period of 3 years was established.According to the idea of nested case-control study, each case was randomly matched with the same gender, age and physical examination time in the same month by using the method of random sampling without putting back.Conditional logistic regression model was established by using the matched data.The diagnostic value of related indicators for NAFLD was analyzed by receiver operating characteristic curve (ROC).Results:A total of 1 194 subjects were included, including 684 males (57.3%, 684/1 194) and 510 females (42.7%, 510/1 194). The age was (50.8±11.6) years.The age ranged from 24.0 to 88.0 years.There were 597 patients with NAFLD, including 342 males and 255 females.Logistic regression analysis showed that body mass index, high density lipoprotein cholesterol, hemoglobin, platelet count, uric acid and urea nitrogen were statistically significant in male model (all P<0.05). Body mass index( OR=1.242, 95% CI 1.143-1.349, P<0.001), hemoglobin( OR=1.034, 95% CI 1.015-1.053, P<0.001), platelet( OR=1.005, 95% CI 1.002-1.009, P=0.005), uric acid( OR=1.004, 95% CI 1.001-1.006, P=0.004), high density lipoprotein cholesterol( OR=0.377, 95% CI 0.184-0.775, P=0.008) and urea nitrogen( OR=0.807, 95% CI 0.693-0.938, P=0.005) were protective factors for NAFLD in male patients..Body mass index( OR=1.552, 95% CI 1.366-1.762, P<0.001), triglyceride ( OR=2.606, 95% CI 1.616-4.204, P<0.001), blood glucose( OR=2.199, 95% CI 1.332-3.631, P=0.002), uric acid( OR=1.005, 95% CI 1.001-1.010, P=0.024) in female model were statistically significant ( P<0.05), and were risk factors for NAFLD in female patients. Conclusion:The incidence rate of NAFLD was different among different gender and age, body mass index, high density lipoprotein cholesterol, hemoglobin, platelet count, uric acid, urea nitrogen, triglyceride and blood glucose were closely related to the incidence of NAFLD.

ABSTRACT

Recently, evidences show that cancer stem cells (CSCs) are a type of cancer cell group with self-renewal and play a huge role in tumor recurrence, metastasis, and drug resistance. Finding new treatment directions and targets for cancer prognosis and reducing mortality has become a top priority. OCT4, as a transcription factor, participates in maintaining the stem characteristics of CSCs, but the mechanism of OCT4 is often overlooked. In this review, we try to illustrate the mechanism by which OCT4 plays a role in CSCs from the perspective of genetic modification of OCT4, non-coding RNA, complexes and signaling pathways associated with OCT4. Our ultimate goal is to provide new targets for cancer treatment to prolong the survival of cancer patients.

ABSTRACT

Objective: To examine the efficacy and safety of pemetrexed plus apatinib for the treatment of advanced non-squamous non-small cell lung cancer (NSCLC) in elderly patients. Methods: Between January 2016 and June 2017, 38 elderly patients with ad-vanced non-squamous NSCLC from Qingdao Municipal Hospital were examined. All patients received first-or second-line therapy. The inclusion criteria were an age of≥65 years, physical status score of 0-2, and expected survival time of>3 months. Eighteen patients were assigned to the test group, and the remaining 20 patients were assigned to the control group. The patients in the test group were treated with pemetrexed plus apatinib, pemetrexed 500 mg/m2 on day 1 and apatinib 250 mg/d on days 1-21. The control group re-ceived pemetrexed in a 21-day cycle until the disease progressed or intolerable adverse reactions developed. The study was reviewed and approved by the medical ethics committee of Qingdao Municipal Hospital. Results: The disease control rates in the test and con-trol groups were 72.2% and 35%, respectively, with a statistically significant difference (χ2=5.265, P=0.022). The median progression-free survival time (PFS) in the test and control groups were 5.7 months [95% confidence interval (CI): 2.8-8.6] and 3.1 months (95% CI:2.7-3.5), with a statistically significant difference (χ2=4.01, P=0.045). The difference in the incidence of hand-foot syndrome and hyper-tension between the two groups was statistically significant (P=0.007 and P=0.016, respectively), with side effects of 1 or 2 degree in most cases, which was acceptable. Conclusions: Pemetrexed plus apatinib has a definite curative effect on advanced NSCLC, with con-trollable adverse reactions.

ABSTRACT

Objective To observe the effect of the 8-word bandage on the walking ability of stroke patients with knee hyperextension. Methods Fifty patients with stroke combined with knee hyperextension were randomly divided into the observation group and the control group with 25 cases in each group. The control group was treated with conventional methods, including Bobath technology, Brunnstrom therapy and motor relearning primarily rehabilitation training. In addition to the conventional methods, patients in the observation group used 8-word bandage to fix knee joint in walking training. Before and after 8 weeks of treatment, Holden walking function classification, 10-meter maximum walking speed and improved Barthel index were adopted to evaluate the walking ability, maximum walking speed and the life ability of the patients. Results There were no significant differences in the scores before treatment between the two groups. The Holden walking function classification, the 10-meter maximum walking speed and the Barthel index scores were significantly improved after 8-week treatment in both two groups (P<0.05), and patient conditions were more significantly improved in the observation group than those of the control group (P<0.05). Conclusion Using 8-word bandage to fix knee joint can significantly improve knee hyperextension in patients with stroke, so as to improve the walking ability and activities of daily living.

ABSTRACT

Objective To investigate the therapeutic effect of modulated medium frequency current therapy (MMFCT) combined with infrared therapy on patients of acute facial neuritis. Methods A total of forty-six patients with acute facial neuritis were divided into two groups (observation group and control group) randomly and medially. Every patient received medication. Meanwhile, observation group received MMFCT and infrared therapy. Before the treatment, and after two and four weeks of treatment, Portmann scale were used to evaluate the autonomic movements of the facial expression muscles on both sides. After 4 weeks of treatment, the outcome was evaluated by House-Brackmann facial nerve grading system. Results There were no significant differences in Portmann scales before treatment between two groups. Portmann scales were higher in observation group than those of control group after two and four weeks of treatment (P<0.05). With the duration of treatment, Portmann scales were increased successively in two groups. The significant difference was found in multiple comparisons between groups. After 4 weeks of treatment, the efficacy was significant in the observation group, compared with control group, the difference was significant (P<0.05). Conclusion Modulated medium frequency current therapy combined with infrared therapy have a better effect than isolated medication.

ABSTRACT

Objective To explore antitumor effect of 131I-Trastuzumab on human epidermal growth factor receptor(HER) 2 overexpressing breast cancer cells and investigate its possible mechanism.Methods The expression levels of HER2 of three different breast cancer cell lines (BT474,MCF-7,HCC1937) were detected with immunofluorescence.Trastuzumab was labeled with 131I using the Iodogen method and 131I-Trastuzumab was isolated with ultrafiltration membrane,then the labeling efficiency,radiochemical purity and immunoreactivity were measured.The effects of 131I,Trastuzumab and 131I-Trastuzumab on viability of BT474 cells were evaluated with cell counting kit-8 (CCK-8) assay.The levels of total Akt and phosphorylated Akt (p-Akt) were detected with Western blot analysis.One-way analysis of variance (ANOVA),ANOVA for factorial design,Bonferroni correction and Pearson correlation analysis were used for data analysis.Results The expression level of HER2 in BT474 cells was much higher than those in HCC1937 and MCF-7 cells.The labeling efficiency,radiochemical purity and immunoreactivity of 131I-Trastuzumab were (89.71± 2.93)%,(91.80±1.43)% and (58.84±3.35)% respectively.131I (4.625 GBq/L),Trastuzumab(125.0 rmg/L) and 131I-Trastuzumab(4.625 GBq/L) exhibited a dose-dependent cytotoxicity against BT474 cells (r =-0.964,-0.912,-0.618;all P<0.05).The cell viability of 131I-Trastuzumab treated gourp (34.73% ±5.03%) was significantly lower than those of 131I and Trastuzumab treated groups (64.36%± 1.51% and 58.09%±4.14%;t=10.373 and 8.180,both P<0.05),and the cell viability of control group was (100.00±4.54)%.131I-Trastuzumab shown a positive multiplicative interaction between 131I and Trastuzumab (F=9.226,P<0.05;CDI =0.929).Western blot results showed that there was no significant difference of total Akt expression among the control group,131I group,Trastuzumab group and 131I-Trastuzmab group (F=0.208,P>0.05).P-Akt expression in both Trastuzumab group and 131I-Trastuzumab group were much lower than those of control group and 131I group (t=12.524,15.984,7.347,10.807;all P<0.05),while there was no significant difference of p-Akt expression between Trastuzumab group and 131I-Trastuzumab group(t =3.460,P>0.05).Conclusions 131I-Trastuzumab may kill HER2 overexpressing breast cancer cells more effectively than Trastuzumab alone.The underlying mechanism may be attributed to that 131I-Trastuzumab may enhance the radiosensitivity by the inhibitory effect on PI3K/Akt pathway and thus exert synergistic effects with 131I.
