Objectives:To analysis the effect of continuous positive airway pressure (CPAP) on nocturnal blood pressure in patients complicated with obstructive sleep apnea-hypopnea syndrome (OSAHS) and different circadian rhythms of hypertension.Methods:A total of 61 eligible patients were monitored by overnight polysomnography (PSG) at the Sleep Center of the Affiliated Huaian No.1 People′s Hospital of Nanjing Medical University between January 2020 and April 2021. During the period of PSG monitoring, continuous non-invasive blood pressure (BP) and heart rate variability (HRV) were monitored simultaneously. Frequency domain analysis was used to measure HRV and low/high frequency was used to indirectly reflect sympathetic activity. According to the nighttime systolic BP decrease rate, patients were divided into three groups: dipper pattern (descent rate ≥10%), non-dipper pattern (descent rate was less than 10% but higher than 0) and reverse dipper pattern (descent rate≤0). The PSG parameters, BP data as well as sympathetic activity etc. were compared within and among groups before and after CPAP treatment. Multiple linear regression analyses were used to explore the influencing factors of antihypertensive effect of CPAP.Results:There were no significant differences in awake systolic BP (SBP) values, the severity of OSAHS, ESS scores, awake sympathetic activity and the other baseline data among the three groups. After CPAP treatment, the mean value of asleep BP in entire group showed a modest decline as compared to the baseline values [SBP decreased 4.6 mmHg (1 mmHg=0.133 kPa); diastolic blood pressure (DBP) decreased 2.4 mmHg, both P<0.001]. Subgroup analysis showed a significant reduction in asleep SBP of 11.1 mmHg and DBP of 4.9 mmHg (both P<0.001) in reverse dipper group, respectively, compared with the baseline values. While in dipper and non-dipper group, there were no significant differences before and after CPAP treatment in terms of BP (both P>0.05). In addition, there was no difference in awake sympathetic activity among three groups, while sleep sympathetic activity showed a gradual increasing trend. Sleep sympathetic activity decreased significantly from baseline after CPAP treatment in reverse dipper group ( P<0.001), while no differences were found in the other two groups before and after treatment. After controlling for baseline data such as age etc., the line regression model showed that the antihypertensive effect of CPAP was correlated with reverse dipper (SBP: β=0.548, P=0.002; DBP: β=0.454, P=0.013) and the improvement of nocturnal MpO 2 (SBP: β=0.410, P=0.046), but not with the severity of OSAHS, daytime sleepiness, or baseline BP values. Conclusion:For patients with moderate to severe OSAHS and hypertension, reverse dipper is an effective indicator to predict the antihypertensive effect of CPAP therapy.

Objectives:To investigate the common risk factors for excess daytime sleepiness (EDS) and hypertension in obstructive sleep apnea-hypopnea syndrome(OSAHS) patients.Methods:Between January 2020 and February 2021, a total of 103 OSAHS patients diagnosed in the Department of Sleep Medicine Center, the Affiliated Huaian No.1 People′s Hospital of Nanjing Medical University were enrolled as the study population. During polysomnography (PSG) monitoring, noninvasive continuous blood pressure (BP) and heart rate variability (HRV) were monitored simultaneously. Low/high frequency components (LF/HF) were used to reflect sympathetic-vagal balance in frequency domain analysis. According to Epworth Sleepiness Scale (ESS) and BP levels, patients were divided into four groups: simple OSAHS group (ESS<10 scores and BP<140/90 mmHg, n=30)(1 mmHg=0.133 kPa), OSAHS+hypertension group (ESS<10 scores and BP≥140/90 mmHg, n=23), OSAHS+EDS group (ESS≥10 scores and BP<140/90 mmHg, n=26) and OSAHS+hypertension+EDS group (ESS≥10scores and BP≥140/90 mmHg, n=24). The clinical and PSG parameters were analyzed and compared among the four groups. Regression analyses were used to explore the common causative factors for EDS and hypertension. Results:The LF/HF in OSAHS+hypertension+EDS group was significantly higher than the other three groups [3.2% (2.6%, 4.2%) vs 1.4% (1.2%, 1.6%), 2.2% (1.8%, 2.9%), 2.5% (1.6%, 3.1%), all P<0.05]. No difference was observed between OSAHS+hypertension group and OSAHS+EDS group ( P=0.779), but both higher than simple OSAHS group. The linear regression equation showed that LF/HF was most correlated with the percentage of sleep time with oxygen saturation<90% (T90) as compared to the other parameters of sleep disordered breathing (β=0.201, P=0.006). In addition, Pearson correlation analysis showed that LF/HF was significantly correlated with ESS scores and asleep BP levels ( r=0.536, r=0.456, all P<0.05). The logical regression equation showed that LF/HF was a causative risk factor for both EDS and hypertension in OSAHS (β=0.164, 95% CI: 1.018-1.364, P=0.028). Conclusion:The sympathetic-vagal imbalance is a common risk factor for EDS and hypertension in OSAHS patients

Prostate cancer is one of the leading cause of male cancer-related death worldwide, and the treatment of high-risk prostate cancer and castration resistant prostate cancer remains a significant challenge. Epigenetic modification has been paid more attention in the field of tumor, as a common RNA modification in eukaryotic cells, N6-methyladenosine (m6A) methylation is a dynamic and reversible process regulated by m6A methyltransferase, demethylase and recognition protein, which can regulate the physiological process and tumor progression by regulating gene expression. m6A modification plays an important role in the occurrence and development of prostate cancer and is expected to become a new target in diagnosis, treatment and prognosis. This article reviews the m6A modification and its expression, function and mechanism in prostate cancer, as well as new ideas for clinical application.

Objective:To investigate the association between oxygen desaturation rate and blood pressure (BP) among severe obstructive sleep apnea syndrome (OSAS) and the possible mechanism.Methods:Patients with snoring were enrolled from the Department of Sleep Medicine Center, the Affiliated Huaian No.1 People′s Hospital of Nanjing Medical University form March 2018 to January 2019 and underwent polysomnography (PSG). Noninvasive BP and Heart rate variability were full-night monitored continuously and synchronized with PSG. Based on the PSG results and exclusion criteria, a total of 86 severe OSAS patients were enrolled in this study and divided into two groups according to the ambulatory BP measurements: hypertensive group ( n=44) and normotensive group ( n=42). Oxygen desaturation rate was expressed as the change in the percentage of pulse oxyhemoglobin saturation (SpO 2) per second during desaturation events after the obstructive apnea events occurred. The PSG parameters were compared between the two group and the multiple regression analyses were used to explore the association between oxygen desaturation rate and BP and its possible mechanism. Results:The apnea-hyperpnoea index (AHI) and respiratory event-related arousals (RERAs) were significantly higher in hypertensive group than those in normotensive group [(69.8±18.2) vs. (56.5±13.9) event/h; (40.5±17.4) vs. (30.2±14.6) event/h, both P<0.01]. In addition, hypoxia exposure conditions in the hypertensive group were more severe than those in the normotensive group, especially oxygen desaturation rate [(0.45±0.14)%/s vs. (0.33±0.10)%/s, P<0.001]. After adjusting for age, sex, neck circumference, waist circumference, smoking, drinking, the regression analyses showed that only the oxygen desaturation rate was significantly associated with both awake and asleep BP in OSAS patients ( β=0.473, 0.478, both P<0.01) and the correlation analyses suggested that the oxygen desaturation rate was related to the both awake and asleep sympathetic-parasympathetic imbalance ( r=0.367, 0.337, both P<0.01). Conclusion:Oxygen desaturation rate is closely related to BP levels in patients with severe OSAS, and the underlying mechanism is associated with the increased sympathetic activity.

Objective:To analyze the predictive value of P504S for pathological upgrading of gastric low-grade intraepithelial neoplasia (LGIN) after endoscopic submucosal dissection (ESD).Methods:Data of 117 patients (119 lesions) who underwent ESD for LGIN at Huadong Hospital from January 2015 to March 2019 were analyzed retrospectively. Biopsy and ESD specimens were collected. According to pathology, specimens were divided into the LGIN group (postoperative pathology of non-upgrade) and the upgrade group (postoperative pathology of upgrade). The positive rates of P504S were compared between biopsy and postoperative specimens of the LGIN group, and between biopsy and postoperative specimens of the upgrade group. The consistency of the expression of P504S was examined between the biopsy specimens and the postoperative specimens in the LGIN group and the upgrade group. Receiver operator characteristic (ROC) curve of the prediction of pathological upgrading was drawn by the results of P504S in biopsy, and the cutoff value of immunohistochemical staining score was calculated.Results:The positive rate of P504S in the biopsy specimens of the LGIN group (46.8%, 36/77) was lower than that in the biopsy specimens of the upgrade group (73.2%, 30/41) with significant difference ( P=0.006). The positive rate of P504S in the postoperative specimens of the LGIN group (51.9%, 40/77) was lower than that in the postoperative specimens of the upgrade group (82.9%, 34/41) with significant difference ( P=0.001). In the LGIN group, the positive rate of P504S in biopsy specimens (46.8%, 36/77) was lower than that in postoperative specimens (51.9%, 40/77) without significant difference ( P=0.289). The expression of P504S was consistent between biopsy specimens and postoperative specimens with good consistency( K=0.793, P<0.001). In the upgrade group, the positive rate of P504S in biopsy specimens (73.2%, 30/41) was lower than that in the postoperative specimens (82.9%, 34/41) without significant difference ( P=0.219). The expression of P504S was consistent between biopsy and postoperative specimens, and the consistency was general ( K=0.579, P<0.001). ROC curve was drawn for the prediction of pathological upgrading by the results of P504S in biopsy, and the cutoff value of immunohistochemical staining score was 100. The sensitivity and specificity of pathological upgrading for positive result were 0.659 and 0.740, respectively. Conclusion:P504S staining of the postoperative specimens facilitates identification of the degree of gastric mucosal neoplasia. When the cutoff value of staining score is 100, the staining of P504S in biopsy tissue plays a role in predicting the pathological upgrading.

Objective To evaluate the value of near focus narrow-band imaging ( NF-NBI ) in differentiating hyperplastic polyp ( HP ) and sessile serrated adenomas/polyp ( SSA/P ) . Methods Data of 65 cases of pathologically confirmed HP or SSA/P with clear NF-NBI images in Huadong Hospital Affiliated to Fudan University from October 2017 to September 2018 were retrospectively analyzed. Three senior doctors observed the images of NF-NBI, including expanded crypt opening ( ECO ) and thick & branched vessel ( TBV) . The results were compared with pathological results in order to analyze differential diagnostic value of ECO and TBV for HP and SSA/P. Results Among 65 lesions, 44 were SSA/P and 21 were HP. The sensitivity, specificity, and accuracy of ECO, TBV, and ECO combined with TBV for differential diagnosis between HP and SSA/P were 80. 3％( 106/132 ) , 85. 7％( 54/63 ) and 82. 1％( 160/195 ); 38. 6％( 51/132) , 82. 5％( 52/63 ) , and 52. 8％( 103/195 ); and 84. 8％( 112/132 ) , 73. 0％( 46/63 ) , and 81. 0％(158/195), respectively. Conclusion ECO under NF-NBI has a high sensitivity for diagnosis of SSA/P . ECO combined with TBV is helpful for differential diagnosis between HP and SSA/P .

Objective To investigate the risk factors of pathological discrepancy between biopsy and excisional specimen from gastric low-grade intraepithelial neoplasia (LGIN) and early gastric cancer (EGC). Methods A retrospective analysis was conducted on the data of 235 patients who underwent endoscopic submucosal dissection or surgical resection and diagnosed as LGIN or EGC ( including high-grade intraepithelial neoplasia) by postoperative pathology. Patients were grouped by whether there was significant pathological discrepancy between biopsy and excisional specimen. Univariate and multivariate analyses were used to analyze the risk factors for significant pathological discrepancy. Results Significant pathological discrepancy occurred in 33 cases (14. 0%). Univariate analysis showed that protruding lesion, non-reddish surface, without erosion or ulcer, diffused pathological type and number of biopsy were related to the pathological discrepancy (all P＜0. 05). Multivariate analysis suggested that small number of biopsy blocks (OR＝0. 574, 95%CI: 0. 363-0. 908, P＝0. 018) was an independent risk factor for significant pathological discrepancy. Conclusion The pathological discrepancy between biopsy and excisional specimen from gastric LGIN and EGC are common. Multiple biopsies can improve the accuracy of biopsy and reduce the occurrence of pathological discrepancy with excisional specimen.

Objective To investigate the role of multi-detector computed tomography (CT) in the diagnosis and classification of isolated spontaneous superior mesenteric artery dissection (ISSMAD). Methods From July 2012 to December 2016, 30 consecutive patients with ISSMAD underwent CT scan at least two times. We retrospectively summarized the clinical characteristics and CT findings of them. The stenosis ratio of true lumen was compared between the patients without bowel ischemia and ones with bowel ischemia. Results There were 5 cases of type I ISSMAD, 14 cases of type 2, 1 case of type 3, 7 cases of type 4 and 3 cases of type V. Intestinal ischemia occurred in 5 patients. The stenosis ratio of true lumen in the patients without bowel ischemia was lower than that with bowel ischemia (45.6% vs. 76.0%, t=-14.5, P=0.000). Five patients with intestinal ischemia underwent superior mesenteric artery stenting and others received conservative therapy. The abdominal pain was alleviated for all the patients after treatment. Follow-up was complete in 30 cases. Follow-up CT angiography of superior mesenteric artery showed dissection remodeling in 12 patients. Conclusion Multi-detector CT is a valuable method in diagnosis and classification of ISSMAD and monitoring the changes of dissection.
