ABSTRACT

@#Objective    To explore the clinical issues associated with video-assisted pulmonary segmentectomy and to provide reference for better implementation of thoracoscopic pulmonary segmentectomy and reduction of perioperative complications through analyzing the clinical results of thoracoscopic segmentectomy. Methods    The clinical data of 90 patients who planned to undergo thoracoscopic segmentectomy in our department from October 2017 to December 2019 were retrospectively analyzed, including 35 males with an average age of 60.34±9.40 years and 55 females with an average age of 56.09±12.11 years. The data including lung nodule number, benign or malignant, preoperative location by Hookwire, preoperative planning and actual implementation, operation time, intraoperative blood loss, postoperative drainage volume and time of drainage tube removal, postoperative hospital stay and complications were collected and analyzed. Results    Among the 90 patients, 38 were preoperatively positioned by Hook-wire, 52 were directly operated on; 87 were completed under thoracoscopic surgery among whom 3 underwent passive lobectomy after segmentectomy under thoracoscopic surgery, and 3 were converted to thoracotomy among whom 1 underwent lobectomy. Operation time was 198.58±56.42 min, intraoperative blood loss was 129.78±67.51 mL, lymph node samples were 6.43±1.41, drainage time was 2.98±1.25 d, the amount of postoperation drainage was 480.00±262.00 mL, hospital stay was 7.60±2.38 d. In all patients, 73 had single nodules and 17 had multiple nodules. Totally 113 pulmonary nodules were resected, 14 (12.39%) were benign nodules and 99 (87.61%) were malignant nodules. There was no perioperative death or serious complications. Conclusion    For those pulmonary parenchymal nodules which meet the  indications, it is feasible to perform thoracoscopic anatomic pulmonary segmentectomy according to preoperative thin-slice CT and three-dimensional computed tomography-bronchography and angiography (3D-CTBA) reconstruction results. Preoperative Hookwire localization can ensure effective edge resection and reduce unplanned lobotomy for intersegmental nodules and non-palpable peripheral pure ground-glass nodules.

ABSTRACT

@#Objective    To investigate the perioperative results and safety of minimally invasive direct coronary artery bypass grafting (MIDCAB) treatment of anterior descending artery disease through a small left thoracic incision assisted by thoracoscopy. Methods    The clinical data of 92 patients who received MIDCAB in our hospital from May 2014 to October 2018 were retrospectively analyzed, including 72 (78.26%) males aged 42-78 (61.2±7.48) years, and 20 (21.74%) females aged 30-80 (61.30±12.26) years. The perioperative complications, blood product use, left heart function changes, ventilator use time, ICU stay, hospital stay and other indicators were analyzed. Results    Two (2.17%) patients were transferred to thoracotomy, 5 (5.43%) patients received blood products during the operation, 2 (2.17%) were subjected to secondary thoracotomy to stop bleeding, 4 (4.34%) had postoperative hypoxemia and 1 (1.08%) was reintubated. The ventilator use time was 3-227 (22.35±35.39) hours, the ICU stay was 16-777 (78.85±108.62) hours, and the postoperative hospital stay was 2-36 (8.86±6.05) days. One (1.08%) patient died in hospital. Conclusion    MIDCAB for anterior descending artery disease has good perioperative results, especially for solitary anterior descending artery disease, which can reduce the use of blood products, and shorten the time of ventilator use after operation, ICU stay and hospital stay.

ABSTRACT

@#Objective    To evaluate the efficacy of hybrid ablation through compared with thoracoscopic epicardial ablation. Methods    In this study, 108 patients with all long-standing persistent atrial fibrillation (LSPAF) received thoracoscopic epicardial ablation (TEA) after enrollment. There were 82 males and 26 females at age of 56.5±9.4 years. After blanking-period, patients off antiarrhythmic therapy with sinus rhythm were divided into a hybrid ablation (HA) group (50 patients) and a TEA group (58 patients). Only patients in the HA group received catheter ablation after randomization subsequently. In at least two-year observation period, cardiovascular risk factors were observed in all groups’ patients. Results    The mean follow-up duration was 17.3-41.8 (26.9±6.1) months and there was no significant difference between two groups [8.2-40.6 (27.5±5.7) months in the HA group and 17.3-41.8 (26.4±6.7) months in the TEA group]. The off antiarrhythmic agents (AADs) sinus rhythm rate was significantly higher in the HA group than that in the TEA group at the time of postoperative 6, 12, 24 and 36 months [96.0%, 90.0%, 83.7%, 83.7% versus 79.3%, 75.9%, 67.3%, 63.1%, HR=0.415 (95%CI 0.206-0.923)]. Conclusion    We can conclude that the efficacy of two-staged hybrid ablation for LSPAF is superior to thoracoscopic epicardial ablation alone. Patients can obtain benefit from a supplemental radiofrequency catheter ablation after blanking-period of surgical ablation, instead of those without a supplemental ablation.

ABSTRACT

@#Objective    To evaluate the efficacy of thoracoscopic complex segmentectomy for stageⅠnon-small cell lung cancer (NSCLC). Methods    We retrospectively reviewed the perioperative clinical data of patients with stageⅠNSCLC who underwent thoracoscopic complex segmentectomy (n=58) or simple segmentectomy (n=33) between January 2017 and March 2020 in our hospital. There were 36 males and 55 females with a median age of 57 years (range: 50-66 years). The clinical data of the two groups were compared. Results    There were no significant differences between the two groups in characteristics including age, sex, weight, comorbidities, preoperative pulmonary function, dominant composition of tumor, tumor histology and size, overall complications, estimated blood loss, prolonged air leakage, length of hospital stay, length of drainage, surgical margin distance or number of dissected lymph nodes. Only the operation time and number of staples for making intersegmental plane were significantly different between the two groups (P<0.05). There was no perioperative death in both groups. Conclusion    Thoracoscopic complex segmentectomy is a feasible and safe technique for stageⅠNSCLC.

ABSTRACT

To explore the effect of Baihe Dihuang Decoction on the synaptic plasticity of hippocampal neurons in rats with anxious depression. Fifty SD rats were randomly divided into normal group, model group, venlafaxine group(6.75 mg·kg~(-1)), high-dose Baihe Dihuang Decoction group(8.64 g·kg~(-1)) and low-dose Baihe Dihuang Decoction group(4.32 g·kg~(-1)). Chronic restraint stress(6 h) combined with corticosterone(ih, 30 mg·kg~(-1)) was used to establish an anxious depression model, and 7 days after modeling, the administration started and continued for 21 days. The anxiety and depression-like behaviors of the rats were evaluated. Golgi-Cox staining and electron microscopy were used to observe the morphology and ultrastructural changes of synaptic dendrites. Immunofluorescence was used to detect the expression of hippocampal synaptic plasticity protein synapsin-1 and postsynaptic density protein 95(PSD-95). Western blot method was used to detect the expression of functional protein synaptophysin(SYP) and synaptic Ras GTPase activating protein(SynGap). The results showed that the rats in the model group had obvious anxiety and depression-like behaviors, the hip-pocampal dendritic spine density and branch length were reduced, the number of synapses was cut, and the internal structure was da-maged. The average fluorescence intensity of synapsin-1 and PSD-95 was significantly reduced and the expression of SYP and SynGap also decreased. High-dose Baihe Dihuang Decoction could significantly improve the anxiety and depression-like behaviors of model rats, relieve synaptic damage, and increase the expression of synapsin-1, PSD-95, SYP, and SynGap proteins. Therefore, we believe that Baihe Dihuang Decoction can improve anxiety and depression behaviors by regulating the synaptic plasticity of hippocampal neurons.

ABSTRACT

The aim of this paper was to observe the effect of Xinfeng Capsules(XFC)-containing serum on the apoptosis and inflammation of fibroblast-like synoviocytes(FLS) in rheumatoid arthritis(RA) induced by tumor necrosis factor-α(TNF-α), so as to investigate the mechanism of XFC in the treatment of RA. RA-FLS immortalized cell line was established, and XFC drug-containing serum was prepared. CCK-8, ELISA, RT-qPCR, immunofluorescence and TUNEL were used to observe the effect of XFC-containing serum on RA-FLS apoptosis and inflammatory indexes. CCK-8 results showed that the optimal concentration and time of TNF-α on RA-FLS were 10 ng·mL~(-1) and 48 h, respectively; and the optimal concentration and time of XFC on RA-FLS were 6.48 mg·g~(-1) and 72 h, respectively. The results of ELISA showed that compared with RA-FLS group, the expressions of TNF-α, IL-1β, IL-6, IL-8 in TNF-α+RA-FLS group were significantly increased, while the expressions of IL-4 and IL-10 were significantly decreased(P<0.01); after intervention with XFC-containing serum, the expressions of TNF-α, IL-1β, IL-6, IL-8 were significantly decreased, whereas the expressions of IL-4 and IL-10 were significantly increased(P<0.01). The results of RT-qPCR showed that compared with RA-FLS group, the mRNA expressions of Fas, FasL, caspase-3, caspase-8, Bax, Bcl-X1 in TNF-α+RA-FLS group were significantly decreased, while the mRNA expression of Bcl-2 was significantly increased(P<0.001); after intervention with XFC-containing serum, the mRNA expressions of Fas, FasL, caspase-3, caspase-8, Bax, Bcl-X1 were significantly increased, whereas the mRNA expression of Bcl-2 was significantly decreased(P<0.01). The results of immunofluorescence showed that compared with RA-FLS group, the protein expressions of caspase-3 and Bax in TNF-α+RA-FLS group was significantly lower than those in RA-FLS group(P<0.05); after intervention with XFC-containing serum, the protein expressions of caspase-3 and Bax were significantly increased, whereas the protein expression of Bcl-2 was significantly decreased(P<0.05). TUNEL results showed that compared with RA-FLS group, the apoptosis of TNF-α+RA-FLS group was decreased(P<0.05); after intervention with XFC-containing serum, the apoptosis was significantly increased(P<0.05). One of the mechanisms of XFC in the treatment of RA is to promote the apoptosis of RA-FLS and inhibit its inflammatory reaction.

ABSTRACT

The aim of this paper was to study the effect and mechanism of fucoxanthin on insulin resistance of obese mice induced by high-fat diet. Fifty C57 BL/6 J male mice were randomly divided into control group and high-fat diet group. The insulin resistance model was induced with high-fat diet for 12 weeks, and model mice were randomly divided into model group, fucoxanthin-0.2% group, fucoxanthin-0.4% group and metformin group. After dietary treatment for 6 weeks, the body weight and epididymal fat weight in each group were measured. Fasting blood glucose(FBG), fasting insulin(FINS), total cholesterol(TC), triglyceride(TG), low-density lipoprotein(LDL-C) and high-density lipoprotein(HDL-C) were measured, and insulin resistance index(HOMA-IR) was calcula-ted. The pathological morphology in liver was observed by hematoxylin eosin staining, and the expressions of some key proteins in insulin receptor substrate 1(IRS-1)/posphoinositide 3-kinase(PI3 K)/serine-threonine kinase(Akt) and peroxisome proliferators-activated receptor-γ(PPARγ)/sterol regulatory element binding protein-1(SREBP-1)/fatty acid synthetase(FAS) pathways in liver were detected by Western blot. According to the findings, compared with the model group, levels of body weight, epididymal fat weight, FBG, FINS, TC, TG, LDL-C and HOMA-IR, as well as protein expressions of PPARγ, SREBP-1 and FAS in liver were significantly reduced(P<0.05 or P<0.01), while level of HDL-C and protein expressions of p-IRS-1, IRS-1, PI3 K and p-Akt in liver were signi-ficantly increased after treatment with fucoxanthin(P<0.05 or P<0.01). And the pathological changes of liver tissue in fucoxanthin-treated mice were also improved obviously. The results showed that fucoxanthin could improve obesity, hyperglycemia and hyperlipidemia, and alleviate insulin resistance in obese mice, and its mechanism is possibly related to the regulation of IRS-1/PI3 K/Akt and PPARγ/SREBP-1/FAS pathways.

ABSTRACT

BACKGROUND@#It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011.@*METHODS@#A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers. The data were reported voluntarily and obtained from a database. We compared the proportion of each procedure in the 7 years before and 7 years after September 30, 2011. The data were analyzed by performing Z test (one-sided).@*RESULTS@#The number of different procedures during October 1, 2011-September 30, 2018 was more than twice that during October 1, 2004-September 30, 2011. Regarding pelvic floor surgeries related to POP, the rate of synthetic mesh procedures increased from 38.1% (5298/13,906) during October 1, 2004-September 30, 2011 to 46.0% (14,107/30,688) during October 1, 2011-September 30, 2018, whereas the rate of non-mesh procedures decreased from 61.9% (8608/13,906) to 54.0% (16,581/30,688) (Z = 15.53, P < 0.001). Regarding synthetic mesh surgeries related to POP, the rates of transvaginal placement of surgical mesh (TVM) procedures decreased from 94.1% (4983/5298) to 82.2% (11,603/14,107) (Z = 20.79, P < 0.001), but the rate of laparoscopic sacrocolpopexy (LSC) procedures increased from 5.9% (315/5298) to 17.8% (2504/14,107).@*CONCLUSIONS@#The rate of synthetic mesh procedures increased while that of non-mesh procedures decreased significantly. The rate of TVM procedures decreased while the rate of LSC procedures increased significantly.@*TRIAL REGISTRATION NUMBER@#NCT03620565, https://register.clinicaltrials.gov.

ABSTRACT

Objective To investigate the distribution characteristics of Oncomelania hupensis in Guangxi Zhuang Autonomous Region, so as to provide insights into the assessment of the risk of schistosomiasis transmission and the scientific formulation of the schistosomiasis surveillance strategy. Methods From 2015 to 2019, a total of 19 national schistosomiasis surveillance sites were assigned in Guangxi Zhuang Autonomous Region, including 4 fixed sites and 15 mobile sites. Snail survey was performed by means of systematic sampling in combination with environmental sampling, and the infection of Schistosoma japonicum was detected by the crushing method combined with loop-mediated isothermal amplification (LAMP) assay. Results From 2015 to 2019, snail habitats were detected at areas of 17 040 to 39 527 m2, including 6 214 m2 emerging snail habitats and 16 563 m2 re-emerging snail habitats. The overall mean density of living snails was 0.019 2 snails/0.1 m2 and the occurrence of frames with snails was 1.11% in the national schistosomiasis surveillance sites; however, no S. japonicum infection was identified in snails. The area of snail habitats increased by 121.46% in the national surveillance sites in 2019 as compared to that in 2015; however, 50.34% (Z = −0.422, P > 0.05) and 42.85% (χ2 = 130.41, P < 0.01) reductions were seen in the overall means density of living snails and the occurrence of frames with snails. All snail habitats were distributed in the 4 fixed surveillance sites, and were mainly found in ditches, paddy fields and dry lands, with weeds as the primary vegetation type. Conclusions There are still risk factors leading to re-emergent transmission of schistosomiasis in Guangxi Zhuang Autonomous Region, such as local snail spread, and the monitoring of schistosomiasis remains to be reinforced to further consolidate the achievements of schistosomiasis elimination in the region.

ABSTRACT

Humans with chronic psychological stress are prone to develop multiple disorders of body function including impairment of immune system. Chronic psychological stress has been reported to have negative effects on body immune system. However, the underlying mechanisms have not been clearly demonstrated. All immune cells are derived from hematopoietic stem cells (HSC) in the bone marrow, including myeloid cells which comprise the innate immunity as a pivotal component. In this study, to explore the effects of chronic psychological stress on HSC and myeloid cells, different repeated restraint sessions were applied, including long-term mild restraint in which mice were individually subjected to a 2 h restraint session twice daily (morning and afternoon/between 9:00 and 17:00) for 4 weeks, and short-term vigorous restraint in which mice were individually subjected to a 16 h restraint session (from 17:00 to 9:00 next day) for 5 days. At the end of restraint, mice were sacrificed and the total cell numbers in the bone marrow and peripheral blood were measured by cell counting. The proportions and absolute numbers of HSC (LinCD117Sca1CD150CD48) and myeloid cells (CD11bLy6C) were detected by fluorescence activated cell sorting (FACS) analysis. Proliferation of HSC was measured by BrdU incorporation assay. The results indicated that the absolute number of HSC was increased upon long-term mild restraint, but was decreased upon short-term vigorous restraint with impaired proliferation. Both long-term mild restraint and short-term vigorous restraint led to the accumulation of CD11bLy6C cells in the bone marrow as well as in the peripheral blood, as indicated by the absolute cell numbers. Taken together, long-term chronic stress led to increased ratio and absolute number of HSC in mice, while short-term stress had opposite effects, which suggests that stress-induced accumulation of CD11bLy6C myeloid cells might not result from increased number of HSC.

ABSTRACT

Objective:To explore the early surgical outcomes of Thoracoscopic Transmitral Myectomy(TTM) on patients with hypertrophic obstructive cardiomyopathy(HOCM).Methods:Preoperative echocardiography and cardiac magnetic resonance were used to evaluate the patient's hypertrophy extent, mitral valve morphology and function. Myocardial resection was performed via the trans-mitral approach under total thoracoscopy, and the surgical methods and early results were analyzed.Results:From April 2019 to October 2019, a total of 15 cases of TTM were performed by a single surgeon in our ward. Preoperative imaging evaluation revealed that 6 patients(40.0%) had predominantly hypertrophic basal septum while another 9 patients(60.0%) had concomitant midventricular septal hypertrophy. Two(13.3%) patients were interrogated ruptured posterior mitral chord by preoperative echocardiogram. After myocardial resection, the mitral valve was treated as follows: 11 patients(73.3%) underwent anterior leaflet enlargement, and 3(20.0%) were directly reattached to mitral valve annulus, and 1(6.7%) underwent bioprosthetic mitral replacement. There was no case of perioperative death, ventricular septal perforation, residual left ventricular outflow tract obstruction and complete atrioventricular block. Median aortic crossclamp time, cardiopulmonary bypass time, postoperative ventilator use time, ICU stay time, and postoperative hospital stay were 129.0min(116.0, 147.0), 184.0 min(158.0, 227.0), 22.0 h(9.0, 26.0), 3 days(2, 7) and 9 days(7, 14) respectively. No patient lost to follow up, the median follow-up time was 4 months(2, 5). One patient(6.7%) underwent mitral angioplasty three months after surgery due to a tear in the A3 area; the ventricular septal thickness and left ventricular outflow tract pressure decreased significantly(preoperative vs follow-up), and were(19.3±3.3)mm vs. (8.9±4.4) mm( P=0.001), (90.8±23.2)mmHg vs. (8.9±4.4) mmHg(1 mmHg = 0.133kPa)( P<0.001) respectively; no residual SAM was observed during follow-up. Patients with moderate-to severe mitral regurgitation were decreased from 12(80.0%) before surgery to 1(6.7%) during follow up( P<0.001). Conclusion:TTM is a safe and effective procedure for HOCM patients with appropriate surgical indications, providing better exposure to septum from basal to apical area, eliminating left ventricular outflow tract obstruction and SAM-related mitral regurgitation. The anterior mitral valve leaflet should be carefully treated during surgery to reduce the occurrence of residual mitral regurgitation resulted in inappropriate selection of patch size and suturing technique.

ABSTRACT

Objective:This study aimed to assess the association between hypertension and carotid plaque in a research population in China.Methods:The subjects of this study were selected from a population undergoing physical examination at the Fourth Medical Center of PLA General Hospital in 2017. We collected information on physical examination, physiological index test, blood pressure indicators were analyzed according as continuous variables (systolic blood pressure, diastolic blood pressure, and pulse pressure) and categorical variables (hypertension and quartile of blood pressure pulse pressure). A multivariate logistic regression model was conducted to estimate the correlation between blood pressure and carotid plaque development.Results:A total of 716 individuals were surveyed, including 321 men (44.8%) and 395 women (55.2%), and the prevalence of hypertension and carotid plaque were 40.9%(293 cases) and 40.4% (289 cases), respectively. The prevalence of carotid plaque was higher in individuals aged ≥60 years, diabetes mellitus, hypertension and increased waist circumference, systolic blood pressure, fasting blood glucose and glycosylated hemoglobin. The prevalence of carotid plaque increased with the increase of the quartile of blood pressure and pulse pressure ( Ptrend<0.05). After adjustment for age, sex, BMI, waist circumference, and total cholesterol, triglyceride, fasting blood glucose, glycosylated hemoglobin, and hemoglobin levels, every 1 mmHg increased systolic blood pressure increases the risk of carotid plaque by 1.4% (95% CI: 1.005-1.024). Compared with the control group, the risk of carotid plaque increased by 86.8% (95% CI: 1.175-2.946) and 84.8% (95% CI: 1.098-3.110) and 119.6% (95% CI: 1.165-4.142) in the group of normal high blood pressure, grade 1 hypertension and grade 2 and grade 3 hypertension, respectively; compared with the control group, the risk of carotid plaque increased by 56.2% in the group of pulse pressure difference≥60 mmHg (95% CI: 1.049-2.326), in which the risk of carotid plaque increased by 73.3% (95% CI: 1.007-2.983) in women with pulse pressure difference≥60 mmHg (1 mmHg=0.133 kPa); in the control group with pulse pressure difference of four categories Q1 (<42 mmHg), the risk of carotid plaque increased by 92.2% (95% CI: 1.173-3.149) and 95.0% (95% CI: 1.147-3.316) in Q3 (50-61 mmHg) and Q4 (≥62 mmHg), respectively. Conclusion:Increased blood pressure or pulse pressure are associated with increased prevalence of carotid plaque. Prevention of elevated blood pressure and pulse pressure might be one of the effective precautions for the prevention of carotid plaque development.

ABSTRACT

Objective:To investigate the application of gradient cushion on prevention of supine hypotension syndrome (SHS) undergoing cesarean section.Methods:450 parturients undergoing cesarean section with spinal and epidural anesthesia, aged 20-45 years, ASA Ⅰ, Ⅱor Ⅲ grades, were randomly assigned into three groups: gradient cushion group (group A), sandbag group (group B) and left-leaning-operating table group (group C), 150 cases in each. The posture intervention was alternated after completion of spinal and epidural anesthesia. Recorded the cases of SHS, and collected systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), respiratory rate (RR) and saturation of pulse oximetry (SpO 2) before anesthesia, 2 min, 5 min, 10 min after anesthesia and prefetus removal from uterus. And assessed the position comfort with surgical posture comfort scale. Results:The incidence of SHS in group A was 8.0%(12/150), in group B was 20.0% (30/150), and in group C was 21.3% (32/150).

ABSTRACT

Objective:To study the mechanism of the effect of Jiajian-Zhujing Decoction on the expression of VEGF on ARPE-19 cells after AKT transfection. Methods:To prepare the serum and blank serum of Jiajian-Zhujing Decoction and divide ARPE-19 cells into the normal group, model group, blank serum group, medicated serum group, Conbercept group and combined group. Except normal group, this research established AKT transfected cell model. Then cultured the normal group and model group with conventional method, and the blank serum group was cultured with 10% blank serum, the medicated serum group was cultured with 10% medicated serum, the Conbercept group was cultured with 20 μg/ml Conbercept, the combined group was cultured with 10% medicated serum and 20 μg/m Conbercept. The proliferation of ARPE-19 cells in each group was detect by the CCK-8 method. The levels of AKT, mTOR and VEGF mRNA were detected by real-time quantitative PCR. Western blot was used to detect the expression of AKT, mTOR and VEGF. Results:After being cultured for 24, 48 and 72 hours, compared with the model group, the cell proliferation rate in blank serum group, medicated serum group, Conbercept group and combined group significantly decreased ( P<0.05). Compared with the model group, the expression of AKT mRNA (24 h: 3.10 ± 0.48, 1.97 ± 0.14, 1.26 ± 0.24 vs. 4.77 ± 0.68; 48 h: 3.52 ± 0.82, 2.62 ± 0.77, 1.10 ± 0.19 vs. 6.12 ± 1.21), mTOR mRNA (24 h: 3.02 ± 0.26, 2.45 ± 0.75, 1.13 ± 0.15 vs. 4.48 ± 0.80; 48 h: 1.29 ± 0.30, 1.30 ± 0.57, 0.65 ± 0.19 vs. 2.54 ± 0.62), VEGF mRNA (24 h: 3.33 ± 0.62, 2.18 ± 0.20, 1.55 ± 0.28 vs. 5.53 ± 1.02; 48 h: 2.35 ± 0.54, 1.23 ± 0.28, 0.93 ± 0.25 vs. 3.59 ± 0.40), AKT protion (24 h: 0.45 ± 0.09, 0.25 ± 0.05, 0.14 ± 0.04 vs. 0.62 ± 0.04; 48 h: 0.36 ± 0.06, 0.23 ± 0.04, 0.14 ± 0.03 vs. 0.54 ± 0.08), mTOR protion (24 h: 0.35 ± 0.05, 0.24 ± 0.02, 0.18 ± 0.02 vs. 0.52 ± 0.09; 48 h: 0.23 ± 0.04, 0.29 ± 0.04, 0.14 ± 0.03 vs. 0.40 ± 0.10), VEGF protion (24 h: 0.14 ± 0.03, 0.33 ± 0.04, 0.24 ± 0.03 vs. 0.54 ± 0.10; 48 h: 0.24 ± 0.03, 0.17 ± 0.02, 0.11 ± 0.02 vs. 0.42 ± 0.10) significantly decreased ( P<0.05), and the combined group was significantly lower than that of the Conbercept group ( P<0.05). Conclusions:AKT transfection can promote the proliferation of ARPE-19 cells, and Jiajian-Zhujing Decoction can significantly inhibit this proliferation. Jiajian-Zhujing Decoction may inhibit the activity of AKT/mTOR signaling pathway to reduce the expression of VEGF.

Objective@#To investigate the application of gradient cushion on prevention of supine hypotension syndrome (SHS) undergoing cesarean section.@*Methods@#450 parturients undergoing cesarean section with spinal and epidural anesthesia, aged 20-45 years, ASA Ⅰ, Ⅱor Ⅲ grades, were randomly assigned into three groups: gradient cushion group (group A), sandbag group (group B) and left-leaning-operating table group (group C), 150 cases in each. The posture intervention was alternated after completion of spinal and epidural anesthesia. Recorded the cases of SHS, and collected systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), respiratory rate (RR) and saturation of pulse oximetry (SpO2) before anesthesia, 2 min, 5 min, 10 min after anesthesia and prefetus removal from uterus. And assessed the position comfort with surgical posture comfort scale.@*Results@#The incidence of SHS in group A was 8.0%(12/150), in group B was 20.0% (30/150), and in group C was 21.3% (32/150). The rate of SHS was higher in group A than other groups (χ2 value was 8.970, 10.653, all P<0.01). The score with surgical posture comfort scale was (47.03 ± 3.01), (38.13 ± 4.70), (36.10 ± 4.04), which was higher in group A than group B or group C, and the score with surgical posture comfort scale was higher in group B than group C (t value was 27.413, 30.227, 2.542, P<0.01 or 0.05).

ABSTRACT

Objective@#This study aimed to assess the association between hypertension and carotid plaque in a research population in China.@*Methods@#The subjects of this study were selected from a population undergoing physical examination at the Fourth Medical Center of PLA General Hospital in 2017. We collected information on physical examination, physiological index test, blood pressure indicators were analyzed according as continuous variables (systolic blood pressure, diastolic blood pressure, and pulse pressure) and categorical variables (hypertension and quartile of blood pressure pulse pressure). A multivariate logistic regression model was conducted to estimate the correlation between blood pressure and carotid plaque development.@*Results@#A total of 716 individuals were surveyed, including 321 men (44.8%) and 395 women (55.2%), and the prevalence of hypertension and carotid plaque were 40.9%(293 cases) and 40.4% (289 cases), respectively. The prevalence of carotid plaque was higher in individuals aged ≥60 years, diabetes mellitus, hypertension and increased waist circumference, systolic blood pressure, fasting blood glucose and glycosylated hemoglobin. The prevalence of carotid plaque increased with the increase of the quartile of blood pressure and pulse pressure (Ptrend<0.05). After adjustment for age, sex, BMI, waist circumference, and total cholesterol, triglyceride, fasting blood glucose, glycosylated hemoglobin, and hemoglobin levels, every 1 mmHg increased systolic blood pressure increases the risk of carotid plaque by 1.4% (95%CI: 1.005-1.024). Compared with the control group, the risk of carotid plaque increased by 86.8% (95%CI: 1.175-2.946) and 84.8% (95%CI: 1.098-3.110) and 119.6% (95%CI: 1.165-4.142) in the group of normal high blood pressure, grade 1 hypertension and grade 2 and grade 3 hypertension, respectively; compared with the control group, the risk of carotid plaque increased by 56.2% in the group of pulse pressure difference≥60 mmHg (95%CI: 1.049-2.326), in which the risk of carotid plaque increased by 73.3% (95%CI: 1.007-2.983) in women with pulse pressure difference≥60 mmHg (1 mmHg=0.133 kPa); in the control group with pulse pressure difference of four categories Q1 (<42 mmHg), the risk of carotid plaque increased by 92.2% (95%CI: 1.173-3.149) and 95.0% (95%CI: 1.147-3.316) in Q3 (50-61 mmHg) and Q4 (≥62 mmHg), respectively.@*Conclusion@#Increased blood pressure or pulse pressure are associated with increased prevalence of carotid plaque. Prevention of elevated blood pressure and pulse pressure might be one of the effective precautions for the prevention of carotid plaque development.

ABSTRACT

OBJECTIVE: To observe the effect of electroacupuncture (EA) stimulation of "Zusanli"(ST36)on gastric function (food consumption and gastric emptying rate) and excitability of hippocampal glutamatergic neurons in mice, so as to explore its mechanism underlying enhancing gastrointestinal function. METHODS: The present study includes 2 parts. 1) C57BL/6 mice were randomly divided into normal and EA groups (n=12 in each group). EA (2 Hz/15 Hz, 1-3 mA) was applied to bilateral ST36 for 20 min, once daily for 7 days. In each group, 6 mice were used to measure the food consumption and gastric emptying rate, and the other 6 mice used to detect the hippocampal glutamate secretion content by using in vivo microdialysis and high performance liquid chromatography. 2) Thirty CaMKIIα-Cre mice received microinjection of a recombinant adeno-associated viral vector containing inhibitory designer receptor exclusively activated by a designer drug (DREADD, AAV-DIO-hM4Di-eYFP) into the hippocampus. Twenty-one days later, 3 mice were selected to observe the expression of eYFP-labeled hM4Di by immunohistochemistry, and 15 mice employed to observe the electrical activities of hM4Di-eYFP positive neurons exposed in chemogenetic activating drug Clozapine N-oxide (CNO) perfusion conditions (n=3) and without CNO in the recording chamber (n=6 in the control and EA groups) by using whole cell patch clamp. The rest 12 CaMKII-Cre mice were equally randomized into AAV-DIO-hM4Di-eYFP+CNO group and AAV-DIO-hM4Di-eYFP+CNO+EA group, and CNO was given by intraperitoneal injection for observing the effect of EA on gastric function. RESULTS: 1) In C57BL/6 mice, compared with the normal group, the food consumption, gastric emptying rate, and the glutamate content in the hippocampus were obviously increased in the EA group (P0.05), suggesting an elimination of EA effect after acute DREADD-mediated activation of the CaMKIIα-positive hippocampal excitatory neurons. CONCLUSION: EA at ST36 can promote food intake and gastric emptying in normal mice but not in CaMKIIα-Cre mice with activated hippocampal hM4Di receptors,suggesting a contribution of the CaMKIIα-positive hippocampal excitatory neurons (glutamatergic neurons in particular) to the enhanced gastrointestinal function of EA at ST36.
