Objective:To explore the clinical application value of DNA image cytometry ploidy analysis (DNA-ICM) in the pathological diagnosis of malignant pleural effusion.Methods:A retrospective case series study was conducted. The clinical data of 101 patients with pleural effusion from October to December 2021 in Shanxi Bethune Hospital were retrospectively analyzed. Liquid-based cytology (LBC) and DNA-ICM were performed on pleural effusion specimens. The sensitivity and specificity of the two methods were compared with the clinical diagnosis, imaging, biopsy, and follow-up results of the patients.Results:Among the pleural effusions of 101 patients, 39 were malignant pleural effusions and 62 were benign pleural effusions. The sensitivity of LBC and DNA-ICM in diagnosing malignant tumor cells in pleural effusions was 74.7% and 94.9%, respectively, and the specificity was 98.4% and 83.9%, respectively; the combination of the two had an increased diagnostic positivity rate compared with that of LBC alone [36.6% (37/101) vs. 28.7% (29/101)]. Seven cases with positive DNA-ICM but negative LBC result were followed up, and 1 case was diagnosed as small cell lung cancer. Conclusions:DNA-ICM can effectively improve the positive cytology detection rate of pleural effusion, and the combined detection of DNA-ICM and LBC can reduce the underdiagnosis rate of cytology, which is of great clinical value in the pathological diagnosis of malignant pleural effusion.

Objective:To compare the dose and image quality of selected photon shield (SPS) technique, organ-based tube current modulation (OBTCM) technique and the combination of these two techniques for reducing the organ dose in head CT examination for infants.Methods:Two anthropomorphic head phantoms (CIRS 1-yr-old and 5-yr-old) were scanned by using Reference mode, Reference + OBTCM mode, SPS mode and SPS + OBTCM mode, respectively. Radiation doses to the lens of the eye, the anterior of the brain, the posterior of the brain, noise level and CNR of orbit and brain in different phantoms were measured and compared by using different scanning modes.Results:Compared with Reference mode, the doses to the lens of the eye in 1-yr-old and 5-yr-old phantom decreased by (21.89 ± 0.01)% and (28.33 ± 0.34)%, respectively. In SPS mode, the reduction in doses to the lens of the eye in 1-yr-old and 5-yr-old phantom were (71.38 ± 1.30)% and (53.72 ± 2.42)%, respectively. In SPS + OBTCM mode, the reduction was (71.12 ± 2.54)% and (55.73 ± 1.90)%, respectively. There was significant difference in the noise level of orbit and brain in different phantoms under various scanning modes ( F=5.67-85.47, P< 0.05). The noise level in OBTCM mode compared with reference mode increased slightly (<1.45 HU) in various phantoms. SPS and SPS + OBTCM mode resulted in a small noise increase (<2.58 HU). There was no significant difference in CNR of different phantoms under various scanning modes ( P>0.05). Conclusions:SPS and SPS + OBTCM mode can significantly reduce the radiation dose of lens and the whole image plane in the head CT scan for infants, with maintaining the image quality.

Kidney pathologic change was inhibited, and FN and NOX-4 expression were markedly decrease in the Andro group.In conclusion,Andro can significantly reduce the diabetic nephropathy in Leprdb/dbmice with spontaneous type II diabetes mellitus.

Objective To investigate clinicopathological significance of atypical squamous epithelium cells which cannot exclude high grade squamous intraepithelial lesions (ASC-H) in the diagnosis of cervical diseases. Methods The results of age, high-risk human papillomavirus DNA (hrHPV DNA) and cervical biopsy in 496 patients with ASC-H from March 2012 to December 2015 in Shanxi Dayi Hospital were analyzed. Results Among 496 ASC-H cases, the proportion of the patients between 40 and 49 years old was the highest [30.8 ％ (153/496)]. HrHPV DNA was detected in 154 cases, and the positive rate was 79.2 ％(122/154), and the positive rate of patients at the age of 18 to 29 years old was the highest [84.2 ％ (16/19)]. The detection rate of cervical intraepithelial neoplasia (CIN) Ⅱand above lesions in 124 cases with cervical biopsy was 66.9 ％ (83/124), including 100 cases with hrHPV DNA positive (80.6 ％) and 24 cases with hrHPV DNA negative (19.4 ％). There were 71 cases (71.0 ％) of CINⅡ, CIN Ⅲ, early squamous carcinoma and squamous cell carcinomas in 100 hrHPV DNA positive patients with cervical biopsy. There were 12 cases (50.0 ％) of CINⅡ/Ⅲ changes in 24 hrHPV DNA negative patients with cervical biopsy, but none in early squamous carcinoma and squamous cell carcinomas was detected, and there was a significant difference between hrHPV DNA positive and negative patients (χ2=3.857, P< 0.05). The positive predictive value, negative predictive value, sensitivity and specificity of hrHPV DNA detection for diagnosis of CINⅡand above lesions were 85.5 ％, 29.3 ％, 71.0 ％ and 50.0 ％, respectively. Conclusions ASC-H strongly predicts CINⅡand above lesions in cervical cytology. The detection of hrHPV DNA has a high positive predictive value for CINⅡand above lesions.
