Objective To study expression of p27 and cyclin D 1 proteins and their significance in non-Hodgkin's lymphoma (NHL).Methods The expression of p27 and cyclin D 1 proteins were detected by imunohistochemical technique in 77 cases of NHL.Results Of 77 NHLs, the positive rates of p27 and cyclin D 1 protein were 51 9% (40/77) and 58 4% (45/77) respectively, and the positive intensity of p27 in low grade group was significantly higher than in high grade group (P

To study the relationship between the different pulse conditions and photoplethymograms, the photoplethysmogram of 432 subjects, including normal pulse condition and 10 commonly - seen abnormal pulse, was examined at Cun - kou area with a BC - 4 quantitative photoplethysmograph. Meanwhile hemodynamic parameters were analysed. As compared with the normal pulse, photoplethysmograms of different pathological pulse conditions at Cun - kou area showed their specifical parameters and the changes of hemodynamic parameters reflected features of cardiovascular pathophysiology formed by different pulse conditions. It suggests that photoplethysmograms at the Cun -kou area can supply objective basis for clinical diagnosis of different pulse conditions.

Objective To investigate the correlation between enlarged perivascular space (EPVS) and post-stroke depression (PSD) in patients with ischemic stroke. Methods Consecutive patients with acute cerebral infarction admitted to hospital from March 2010 to March 2014 were enroled prospectively. The patients completed head MRI examination after admission and performed EPVS grading. At 3 months after symptom onset, they performed PSD assessment according to Hamilton Depression Scale (HAMD) and Classification and Diagnostic Criteria of Mental Disorders in China, 3rd edition (CCMD-3). The relationship between EPVS and PSD was analyzed. Results A total of 249 patients were enroled; including 62 patients (4. 9% ) experienced PSD at 3 months. There were significant differences in the proportions of the EPVS classification patients of the baseline National Institutes of Health Stroke Scale score ( the median [interquartile range]; 4 [3 - 6] vs. 3 [2 - 5]; Z = - 2. 950, P = 0. 003), centrum semiovale (χ2 = 14. 370, P = 0. 001), and periventricular (χ2 = 11. 590, P = 0. 003)between the PSD group and the non-PSD group. Multivariable logistic regression analysis showed that centrum semiovale EPVS grade 2 (odds ratio [OR] 3. 89, 95% confidence interval [ CI] 1. 59 - 9. 56) and grade 3 (OR 3. 28, 95% CI 1. 04 - 10. 33) were significantly correlated with PSD; periventricular EPVS grade 2 (OR 0. 72, 95% CI 0. 27 - 1. 91) and grade 3 (OR 2. 24, 95% CI 0. 68 - 7. 37) were not correlated with PSD. Conclusions Centrum semiovale EPVS is independently associated with PSD, and periventricular EPVS is not.

Messenger RNA(mRNA) CCT6A can encode chaperone proteins and plays an important role in malignant tumors such as colorectal cancer, lung cancer and breast cancer. CCT6A is highly expressed in malignant tumors, which can be used as a biomarker to assess patients' prognosis, and promote malignant biological behaviors such as tumor proliferation and metastasis by regulating transforming growth factor β signals, cell cycles, and other pathways. CCT6A can also modulate immune cell infiltration in the tumor microenvironment and may be a potential target for tumor immunotherapy. The paper reviews the expression and function of CCT6A in malignancies.

Objective:To investigate the prevalence of thyroid nodules (TN) among people undergoing physical examination in Taiyuan City, and evaluate the impact of hyperuricemia (HUA) on the risk of TN.Methods:Using a prospective design, a total of 42 966 people who underwent routine physical examination at Shanxi Shangning Health Examination Center from October 2020 to October 2021 were selected as subjects and divided into the HUA group ( n = 7 235) and the non-HUA group ( n = 35 731) based on the serum uric acid levels. The propensity score matching (PSM) method was used to balance the confounding factors between groups, and logistic regression was used to analyze the impact of HUA on the risk of TN. Results:The total detection rate of TN in the physical examination population was 55.6% (23 907/42 966). The detection rate of TN in females [61.0% (15 011/24 618)] was higher than that in males [48.5% (8 896/18 348)], and the difference was statistically significant (χ 2 = 664.55, P < 0.001). A total of 2 438 pairs of matching data were obtained after PSM, and the distribution of confounding factors in HUA and non-HUA groups reached equilibrium (the absolute values of standardized differences < 0.10). Logistic regression analysis before PSM showed that HUA was a protective factor for the incidence of TN in general population and males [odds ratio ( OR) = 0.696, 0.817, 95% confidence interval ( CI): 0.661 - 0.732, 0.768 - 0.868], while HUA was a risk factor for the incidence of TN in females ( OR = 1.370, 95% CI: 1.192 - 1.574). After PSM, HUA was not a influencing factor for the incidence of TN in general population and males ( P > 0.05), but it was still a risk factor in females for the onset of TN ( OR = 1.373, 95% CI: 1.014 - 1.858). Conclusion:In the physical examination population in Taiyuan City, HUA is an independent risk factor for TN in females.
