Objective To investigate use of oral antihypertensive drugs among community hypertensive patients in Shanghai and find out factors related to their unreasonable use to direct their clinical use. Methods Seven hundred and three hypertensive patients were surveyed with questionnaire by stratified cluster sampling at three neighborhoods and one village of Dahua community, Baoshan district, Shanghai during April to June 2009 to understand their use of antihypertensive agents, including kinds and forms of drugs, rationale of drug use. Results Five hundred and eighty-two (82. 8% ) of 703 hypertensive patients interviewed were using antihypertensive drugs, 271 (38. 5% ) of them used only one kind of non-compound antihypertensive drug, 182 (25.9%) used one kind of compound agent, 311 (53.4%) used two or more kinds of drugs in combination, including 117 patients ( 16. 8% ) used two kinds of agents combined and 12 patients ( 1.6% ) used three kinds of agents combined. Two hundred and sixty-six (47.5%) patients took orally calcium-channel blockers and 205 ( 35.2% ) used compound agents. Conclusions Frequency of combined use of two or more kinds of antihypertensive agents is reasonable and significantly higher than that of use of one kind of drug at Dahua community in Shanghai. Calcium channel blocker plays a predominant role in treatment for hypertension, non-long-acting compound agents are used in a higher proportion. But,guidelines for hypertension prevention and treatment are not so well complied with in local hypertensive patients. So, it is suggested that training for community physicians and management for standard use of antihypertensive agents at community should be strengthened further.

Objective To explore the effect of LncRNA HOXD-AS1 on the radiosensitivity of H460 cells by targeting the regulation of miR-454-3p expression. Methods H460 cells were irradiated with 0, 2, 4, 6 and 8 Gy, and the expression levels of HOXD-AS1 and miR-454-3p were detected by qRT-PCR. Cell apoptosis rate were measured by flow cytometry experiments. Cell cloning experiments were used to detect cell radiosensitivity. The protein expression levels of Caspase-3, Cyclin D1 and γ-H2AX were detected by Western blot. Results The expression of HOXD-AS1 in H460 cells was significantly increased after X-ray irradiation ( P<0.05) , while the expression of miR-454-3p was significantly decreased ( P<0.05) . Silencing HOXD-AS1 significantly promoted apoptosis, increased radiosensitivity of lung cancer cells, promoted Caspase-3, γ-H2AX protein expression, and inhibited Cyclin D1 expression. HOXD-AS1 could target the expression of miR-454-3p. Conclusion Silencing HOXD-AS1 can promote the apoptosis of lung cancer cells and inhibit cell survival by targeting miR-454-3p to increase the radiosensitivity of lung cancer cells.

Objective:To investigate the efficacy and safety of recombinant tissue plasminogen activator (rt-PA) intravenous thrombolysis combined with edaravone dexborneol at different timing in super elderly patients (aged≥85 years) with moderate to severe acute ischemic stroke (AIS).Methods:A prospective study was performed. Seventy-one super elderly patients with moderate to severe AIS treated with rt-PA intravenous thrombolysis combined with edaravone dexborneol from December 2020 to March 2023 in Department of Neurology, Affiliated Fourth Central Hospital of Nankai University were selected and randomly divided into early group ( n=35) and advanced group ( n=36); patients in the early group were given edaravone dexborneol immediately after rt-PA intravenous thrombolysis, and patients in the advanced group were given edaravone dexborneol 24 h after rt-PA intravenous thrombolysis. In addition, 31 patients with moderate to severe AIS received rt-PA intravenous thrombolysis only in Department of Neurology of the hospital from August 2018 to December 2020 were selected as control group. Differences in efficacy and safety indexes among the 3 groups were compared. Results:After 7 d of treatment, the improvement rate of neurological function in early group was significantly higher than that in control group and advanced group ( P<0.05). After 90 d of treatment, modified Rankin scale (mRS) scores in early group were statistically lower than those in control group and advanced group ( P<0.05); good prognosis rate in early group was statistically higher than that in control group and advanced group ( P<0.05). The incidences of intracranial hemorrhage and symptomatic intracranial hemorrhage in early group were significantly lower than those in control group and advanced group ( P<0.05). After 30 and 90 d of treatment, the advanced group had significantly lower mortality than the control group, but significantly higher mortality than the early group ( P<0.05). Conclusion:Edaravone dexborneol immediately after rt-PA intravenous thrombolysis is the optimal timing for super elderly patients with moderate to severe AIS, which can improve the efficacy and safety.

Objective:To observe the clinical features of uveal metastases from lung carcinoma.Methods:A retrospective case study. From 1983 to 2014, 14 patients with uveal metastases of lung cancer confirmed by ocular examination in Peking Union Medical College Hospital were included in the study. Among them, 7 were male, 7 were female; 11 were monocular and 3 were binocular. The mean age was 54.5±9.6 years. Pathologic examination showed primary bronchial lung cancer, including 13 patients of non-small cell lung cancer (10, 2 and 1 patients of lung adenocarcinoma, squamous cell carcinoma and adenosquamous cell carcinoma, respectively) and 1 patient of small cell lung cancer. Four patients (28.6%) were diagnosed with lung cancer before ophthalmology consultation, and 10 patients (71.4%) were first diagnosed with ophthalmology due to ocular symptoms. The duration from ocular symptoms to lung cancer diagnosis was 1 week to 6 months. The course from diagnosis of lung cancer to ophthalmological consultation was ranged from 10 to 60 months, and the average course was 29.5±19.0 months. There were 7, 4 and 3 patients with impaired vision, occlusion of visual objects and deformation of visual objects, respectively. All patients underwent visual acuity, slit lamp microscope, B-mode ultrasound and UBM examinations. FFA was performed in 8 eyes, and 2 eyes were examined for ICGA. Orbital MRI was performed in 5 patients. Vitreoretinal surgery was performed on 1 eye. The clinical characteristics of the patients were analyzed and observed.Results:In 17 eyes, there were 2 eyes with visual acuity of light perception, 3 eyes of hand movement to counting finger before the eyes, 5 eyes of 0.1- 0.3, 4 eyes of 0.4-0.6, 3 eyes of greater than 0.8. Metastatic cancer was located in iris in 1 eye, it presents as a red mass with irregular shape on the surface, which is full of small nourishing blood vessels. Metastatic cancer were located in choroid in 16 eyes, they presented yellowish-white or grayish-yellow lumps under the posterior pole or equatorial retina, including 14 eyes with a single lesion and 2 eyes with 2 lesions, with retinal detachment in 8 eyes and increased intraocular pressure in 5 eyes. B-mode ultrasonography showed posterior polar flat or surface irregular wavy intraocular space occupying lesions with localized or extensive retinal detachment. FFA and ICGA showed the focal, apical and patchy fluorescence of the tumor. MRI showed that T 1WI medium and high signal consistent with the vitreous body, while T 2WI showed low signal. Conclusions:Uveal metastatic may be the first manifestation of lung cancer, and visual impairment, part of solid mass lesions with fundus flattening may be accompanied by secondary glaucoma and retinal detachment as the main clinical manifestations. Most of the metastatic sites are located in choroid, which is more common in single eye and single lesion. Adenocarcinoma is the most common type of uveal metastasis in non-small cell lung cancer.

Objective: To investigate the mechanism of lncRNA XIST (XIST) on modulating gastric cancer progression via regulating miR-337-3p/HOXC8 axis. Methods: A total of 58 cases of gastric cancer tissues and corresponding para-cancerous tissues resected from March 2013 to January 2018 in Department of General Surgery, Kailuan General Hospital of Tangshan City were collected for this study; in addition, human gastric cancer cell lines (AGS, MGC803, HGC27) and human gastric mucosal GES-1 cells were also collected. qPCR was used to detect the expressions of XIST and miR-337-3p in above mentioned gastric tissues and cell lines. XIST-knockdown vectors, miR-337-3p mimics, miR-337-3p inhibitor and HOXC8-overexpression vectors were transfected into AGS cells. The proliferation and invasion of AGS cells were detected by CCK-8 and Transwell experiments respectively, and the expression levels of HOXC8, E-cadherin, N-cadherin and vimentin were detected by WB. The targeting relationships between XIST, miR337-3p and HOXC8 were verified by dual-luciferase reporter gene assay. Results: XIST was up-regulated in gastric cancer tissues and cell lines (all P<0.01). XIST knockdown significantly inhibited proliferation, invasion and EMT of AGS cells (P<0.05 or P<0.01). Moreover, XIST directly interacted with miR-337-3p and down-regulated its expression, while HOXC8 was the target gene of miR-3373p. Furthermore, XIST knockdown suppressed proliferation, invasion and EMT ofAGS cells through up-regulating the inhibitory effect of miR-337-3p on HOXC8 (P<0.05 or P<0.01). Conclusion: XIST knockdown can suppress the proliferation, invasion and EMT of AGS cells, which may be related with down-regulation of HOXC8 by targeting miR-337-3p.

ObjectiveTo explore the prevalence rate and related risk factors of anxiety, depression and insomnia symptoms in close contacts of COVID-19 patients undergoing centralized quarantine and observation, so as to provide references for follow-up targeted psychological crisis intervention. MethodsFrom February 6 to 8, 2020, a total of 136 close contacts at designated quarantine sites in four districts and counties of Ya'an city were enrolled, and assessed using the general information questionnaire, Hospital Anxiety and Depression Scale (HAD) and Insomnia Severity Index (ISI). ResultsA total of 26 quarantined individuals (19.12%) had various degrees of anxiety, depression or insomnia, including 16 cases (11.76%) with anxiety, 9 cases (6.62%) with depression and 16 cases (11.76%) with insomnia. Correlation analysis showed that HAD (A) score was positively correlated with HAD (D) score (r=0.642, P<0.01). HAD (A) score was positively correlated with ISI score (r=0.590, P<0.01). HAD (D) score was positively correlated with ISI score (r=0.329, P<0.01). Multivariate Logistic regression analysis showed that the risk factor of anxiety was the first week of isolation (OR=3.290, P<0.05), meantime, the risk factors of insomnia included the old age (OR=7.990, P<0.05) and the first week of isolation (OR=4.659, P<0.05). ConclusionThe close contacts of COVID-19 infections undergoing centralized quarantine and observation in Ya’an have high prevalence rate of anxiety and insomnia, and the symptoms are most severe during the first week of quarantine.
