Long-term hypertension causes excessive vascular remodeling and leads to adverse cardiovascular events. Balance of ubiquitination and deubiquitination has been linked to several chronic conditions, including pathological vascular remodeling. In this study, we discovered that the expression of ubiquitin-specific protease 25 (USP25) is significantly up-regulated in angiotensin II (Ang II)-challenged mouse aorta. Knockout of Usp25 augments Ang II-induced vascular injury such as fibrosis and endothelial to mesenchymal transition (EndMT). Mechanistically, we found that USP25 interacts directly with Forkhead box O3 (FOXO3) and removes the K63-linked ubiquitin chain on the K258 site of FOXO3. We also showed that this USP25-mediated deubiquitination of FOXO3 increases its binding to light chain 3 beta isoform and autophagosomic-lysosomal degradation of FOXO3. In addition, we further validated the biological function of USP25 by overexpressing USP25 in the mouse aorta with AAV9 vectors. Our studies identified FOXO3 as a new substrate of USP25 and showed that USP25 may be a potential therapeutic target for excessive vascular remodeling-associated diseases.

Objective:To investigate the incidence of Helicobacter pylori ( Hp) infection in diabetes and cardiovascular diseases. Methods:A total of 500 people who received physical examination in Wuzhou Red Cross Hospital from June 2021 to May 2022 were randomly selected for this study. Hp detection was performed in all people included in this study. The Hp infection rate in patients with diabetes and cardiovascular disease were analyzed. Results:The Hp infection rate in healthy people, patients with diabetes mellitus, cardiovascular disease, or diabetes mellitus complicated by cardiovascular disease was 29.3%, 70.3%, 58.5%, and 90.2%, respectively, with a statistically significant difference ( χ2 = 106.45, P < 0.001). The Hp infection rate of patients with diabetes complicated by one, two, three or more cardiovascular diseases was 83.9%, 94.6%, and 100.0%, respectively, with a statistically significant difference ( χ2 = 8.82, P < 0.001). Conclusion:The Hp infections rate in patients with diabetes complicated by cardiovascular disease was higher than that in patients with diabetes mellitus or cardiovascular disease, in particular in patients with diabetes mellitus complicated by several cardiovascular diseases.

In this study, sonography video urodynamic studies (SVUDS), which combined synchronically urodynamic studies with trans-perineal and trans-abdominal sonography, were used to detect female bladder outlet obstruction (FBOO). The dynamic changes of urethra and surrounding pelvic floor structure during storage and voiding phase were observed by SVUDS and the causes of FBOO were analyzed. And the findings were as follows: 13 patients showed organ prolapse, there was an urethral angulation deformity during urination; 5 cases had abnormal urination as the urethral opening was not good in the middle of urination period; 4 cases had urethral stricture, as the proximal end of the obstruction dilated during urination, and the obstruction site showed no relaxation; 1 case had primary bladder neck obstruction with an incomplete opening of the bladder neck during urination; 3 cases had idiopathic bladder outlet obstruction and the sphincter of bladder neck and urethra opened well during urination.

Objective:To understand the oral health status of urban and rural residents in China,the Fourth National Oral Health Epidemiological Survey (FNOHES) was conducted in 2015.Materials and methods:Based on the principles of multi-stage,stratified,equal capacity,and random sampling,the subjects included five groups of residents aged 3-5,12-15,35-44,55-64,and 65-74 years in all 31 provinces,municipalities,and autonomous regions except Hong Kong,Macao,and Taiwan.The total sample size was 172,425.The survey covered two areas,namely oral health status and knowledge,attitude and oral health behavior.Results:Residents in China had serious caries and poor periodontal condition.The prevalence of caries was above 50％ in all age groups,subjects without periodontal disease accounted for ＜50％,and fewer than 50％ of subjects brushed their teeth twice a day.Based on the results of the FNOHES,the following suggestions were proposed for improving the oral health in China in the future:to establish and improve the comprehensive prevention and control system for oral diseases,implement a comprehensive prevention and control strategy for priority groups,strengthen the oral health education for all people to improve oral health literacy,enhance dynamic monitoring to scientifically evaluate oral health status,and coordinate multi-party resources to establish and improve the oral health service security system.Conclusion:The oral health status of Chinese residents and their oral health behavior habits need to be improved.With the support of the administrative departments of the government and unremitting efforts of the oral health staff,all sectors of society must be coordinated to strengthen oral health education for the whole population.Furthermore,comprehensive prevention and control measures must be implemented for priority groups.

Objective To investigate the incidence and predictors of cerebral infarction in patients with ruptured ACoA aneurysms, and to provide diagnostic and therapeutic information.Methods A total of 319 patients with ruptured ACoA aneurysms in our hospital from January 2009 to February 2015 were reviewed in this study. The author collected data regarding clinical characteristics, and measured the aneurysm morphologies on CTA images. Age, flow angle, vessel angle were analyzed by independent-samples t tests in patients with or without cerebral infarction. Mann-Whitney U tests were used for aneurysm size, aneurysm height, perpendicular height, neck size, size ratio, aspect ratio, aneurysm angle , World Federation of Neurosurgical Societies (WFNS) grade at admission and Fisher grade. Chi-square tests and Fisher's exact tests were used for sex, histories of hypertension, smoking and stroke, treatment modalities, anterior cerebral A1 segment configuration and angiographic vasospasm on CTA images. The multivariate logistic regression analyses were used to determine the independent risk factors of cerebral infarction using the stepwise regression method. Results Of the 319 patients, there were 253 without and 66 patients with cerebral infarction. Differences of age(53±11 vs 57±12,respectively;t=-2.415, P=0.016), Fisher grade [Ⅰ 23(9.1%), Ⅱ 27(10.7%), Ⅲ 74(29.2%), Ⅳ 129(51.0%) vs Ⅰ 1(1.5%), Ⅱ 7 (10.6% ), Ⅲ 13(19.7% ), Ⅳ 45(68.2% ), respectively;Z=-2.541, P=0.035] and treatment modalities [endovascular coil embolization 155(61.3% ), neurosurgical clipping 98(38.7% ) vs endovascular coil embolization 23(34.8%), neurosurgical clipping 43(65.2%), respectively;χ2=14.810, P<0.001] reached statistical significance. Multivariate analysis showed that Fisher grade Ⅳ(OR=10.36,95%CI 1.34-80.29, P=0.025) and neurosurgical clipping (OR=3.28, 95% CI 1.84-5.86,P<0.001)still had statistical significance. Conclusions Cerebral infarction in patients with ruptured ACoA aneurysms may be associated with Fisher grade and treatment modalities. Although there is difference between the two groups in age, it is not a predictor of the occurrence of cerebral infarction.

In this research, Casuarina eguisetifolia Linn was used to verify the broadly suitability of DNA bar-codes in identification of Li-medicine plants and systematic development of species. The genomic DNA of 22 samples collected C. eguisetifolia and its adulterants were amplified by 4 pairs of primers respectively (ITS (inter-nal transcribed spacer), ITS2 (internal transcribed spacer 2), trnH-psbA , rbcL) and sequenced bi-directionally. Obtained sequences were assembled using CodonCode Aligner. The dates were analysised using MEGA5.1 in ac-cordance with the kimura 2-parameter (K2P) model. The neighbor-joining (NJ) phylogenetic trees were construct-ed. Our study demonstrated the efficacy of ITS/ITS2 to distinguish between C. eguisetifolia and other adulterants species at the molecular level. Comparative to the primer of trnH-psbA and rbcL, there was a obviously DNA gap. The NJ trees showed that the several species of Casuarina can be classified to same types to show a obvi-ously monophyly, which the nearest family was Guttiferae. Therefore, ITS/ITS2 regions can accurately distinguish the original plant of Li-medicine. The systematic evolution of Casuarina can be verified in the molecular level.

Objective To observe the therapeutic effects of end-to-side and side-to-side portal vein-hepatic artery shunts (P-H shunt) in pigs with liver cirrhosis and portal hypertension.Methods There were 15 pigs in each group (control and experimental),and the P-H shunt was made in each animal to observe the process of blood flow into the liver and the reduction of portal vein blood pressure.Results The portal vein pressures before the P-H shunt of pigs in the control and experimental group were (20.51±0.74) cm H2O (1 cm H2O=0.098 kPa) and (30.82±2.53) cm H2O respectively (P＜0.05).Portal vein pressures 30 days after the P-H shunt were(19.75±0.84) cm H2O and (20.84± 1.36) cm H2 O respectively (P＞0.05).The portal vein pressure differences of pigs in the control and experimental group before P-H shunt were (7.20±0.34) cm H2O and (17.34±0.62) cm H2O respectively (P＜0.05).Pressures differences 30 days after the P-H shunt were (6.40±0.21) cm H2O and (7.84 ± 1.32) cm H2O respectively (P＜0.05).Splenic vein injection of methylene blue after the P-H shunt operation stained the liver well.No necrosis and hepatic encephalopathy occurred for 30 days after the P-H shunt,and the splenomegaly gradually returned to normal.Liver function was most affected after the operation and other biochemical markers were least affected.Conclusions The P-H shunt changed the channel of blood flow into the liver,the portal hemodynamic was not affected,and a new balanced mechanism was established to maintain the portal hemodynamic stability.However,further treatment was needed for liver function recovery.
