ABSTRACT
Objective:To explore the effects of pressure controlled ventilation-volume guaranteed (PCV-VG) mode on intraoperative pulmonary ventilation and postoperative pulmonary complications (PPC) in elderly patients undergoing thoracoscopic lobectomy.Methods:Sixty patients of American Society of Anesthesiologists (ASA) classification Ⅱor Ⅲ, aged 65-80 years old, with body mass index (BMI) 18-30 kg/m 2, received thoracoscopic lobectomy under general anesthesia from November 2021 to June 2022 in the Second Hospital of Shanxi Medical University were recruited. The patients were divided into PCV-VG and volume-controlled ventilation (VCV) groups using the randomized number table method, with 30 patients in each group. The ventilatory parameters of two-lung ventilation were set to respiratory rate (RR) at 10-12 breaths/min, with a tidal volume (VT) of 8 ml/kg (ideal body weight). The ventilatory parameters of one-lung ventilation (OLV) were set at 12-16 breaths/min, with a VT of 6 ml/kg (IBW). The peak airway pressure (Ppeak), plateau airway pressure (Pplat), driving pressure (ΔP), dynamic lung compliance (Cdyn), end-tidal carbon dioxide (ETCO 2), heart rate (HR), mean arterial pressure (MAP), partial pressure of oxygen (PaO 2) and partial pressure of carbon dioxide (PaCO 2) were obtained at 1 min before OLV (T 0), 30 min after OLV (T 1) and 60 min after OLV (T 2). The incidence and severity of PPC, chest tube duration time and postoperative hospital stay time were recorded. Results:The Ppeak, Pplat and ΔP were higher and Cdyn was lower in both groups at T 1-T 2 than at T 0 (all P<0.001). The Ppeak, Pplat and ΔP were higher and Cdyn was lower in PCV-VG group than in VCV group (all P<0.05). There were no statistical differences in HR, MAP, ETCO 2, PaO 2 and PaCO 2 between the two groups (all P > 0.05). There were no statistical differences in the incidence of PPC [43.3% (13/30) vs. 30.0% (9/30)] and chest tube duration time [(4.4±0.9) d vs. (4.2±1.2) d] between VCV group and PCV-VG group (all P>0.05). Compared with VCV group, the proportion of patients with ≥grade 2 PPC was lower in PCV-VG group [10.0% (3/30) vs. 36.7% (11/30), χ2=5.96, P<0.05]. The postoperative hospital stay time in PCV-VG group was shorter than that in VCV group [(6.4±1.3) d vs. (8.0±1.9) d, t = 4.85, P<0.05]. Conclusions:PCV-VG mode can effectively reduce the severity of PPC, shorten the postoperative hospital stay time and improve the prognosis in elderly patients undergoing thoracoscopic lobectomy.

ABSTRACT
Objective:To explore the mediating role of self-perceptions of aging between frailty and cognitive function in community-dwelling older adults.Methods:From February to July 2021, a total of 528 elderly people in Xinxiang community were investigated with the frailty phenotype, the brief self-perceptions ageing questionnaire and the Mini-mental state examination(MMSE) scale.According to the MMSE total score and education level, the subjects were divided into cognitive impairment group (illiteracy≤17, primary school≤20, junior high school and above≤24, n=74) and cognitive normal group( n=454). SPSS 25.0 software was used for common method deviation test, descriptive statistics and correlation analysis, while AMOS 24.0 software was used to build structural equation model and Bootstrap method was used for intermediary effect test. Results:(1)The prevalence of cognitive impairment among the elderly in the community was 14.1%. The differences between the cognitively normal group and cognitively impaired group were statistically significant in terms of age, education, number of chronic diseases suffered and depression ( χ2=59.21, 6.53, 9.84, 25.47, all P<0.05). The differences were statistically significant in terms of frailty( χ2=75.65, P<0.001) and self-perceptions of aging ( t=77.67, P<0.001). (2)Self-perceptions of aging in the cognitively impaired group (47.39±8.66) was higher than that in the cognitively normal group (38.22±8.24) ( t=77.67, P<0.001) .Frailty score in cognitively impaired group (2.00 (1.00, 3.00)) was higher than that in the cognitively normal group (0.00 (0.00, 1.00))( Z=-8.63, P<0.001) . (3)Frailty was negatively correlated with cognitive function ( r=-0.492, P<0.01), and positively correlated with self-perceptions of aging ( r=0.540, P<0.01). Self-perceptions of aging was negatively correlated with cognitive function ( r=-0.541, P<0.01) . After controlling the influencing factors such as age, education level, chronic diseases and depression, the correlation was still significant (all P<0.01) . (4) Self-perceptions of aging played a partially mediating role in the relationship between frailty and cognitive function, the mediating effect accounted for 58.5% of the total effect. Conclusion:Frailty and self-perceptions of aging have a significant impact on the cognitive function of the elderly in the community, and self-perceptions of aging plays a partial intermediary role between the frailty and cognitive function of the elderly in the community.
ABSTRACT
Objective:To investigate the lung protective effect of driving pressure-guided lung protective ventilation strategy (LPVS) combined with pressure-controlled ventilation (PCV) in elderly patients undergoing thoracoscopic radical resection of lung cancer.Methods:One hundred elderly patients scheduled for thoracoscopic radical resection of lung cancer from April 2021 to April 2022 in the Second Hospital of Shanxi Medical University were selected. Patients were aged 60-80 years old and American Society of Anesthesiologists (ASA) classification Ⅰ-Ⅱ. All patients were divided into 4 groups by using the random number table method, with 25 cases in each group. Group A received volume-controlled ventilation (VCV) + 5 cm H 2O (1 cm H 2O = 0.098 kPa) PEEP, group B received PCV+5 cm H 2O PEEP, group C received VCV+driving pressure-guided individualized PEEP, and group D received PCV+driving pressure-guided individualized PEEP. The arterial oxygen partial pressure (PaO 2) was recorded before one-lung ventilation (OLV) (T 0), 30 min after OLV (T 1) and 60 min after OLV (T 2). The serum concentrations of neutrophil elastase (NE) in radial artery blood samples of patients were measured at T 0 and 10 min after the end of OLV (T 3). The occurrence of postoperative pulmonary complications (PPC) within 5 d after surgery was recorded. Results:The PaO 2 of group A and B at T 1 [(135±50), (146±51) mmHg (1 mmHg = 0.133 kPa)] and T 2 [(137±46), (143±47) mmHg] were lower than those of group C and group D at T 1 [(168±27), (190±30) mmHg] and T 2 [(180±30), (183±24) mmHg] (all P < 0.05). The incidence of PPC within 5 d after surgery in group A was higher than that in group D [36% (9/25) vs. 4% (1/25)] ( P = 0.005). The concentration of NE at T 3 in group A [(202.8±9.7) ng/ml] was lower than that in group B, C and D [(182.5±12.0), (180.0±10.3), (160.6±13.0) ng/ml] ( P < 0.05). Conclusions:During OLV, driving pressure-guided LPVS combined with PCV can not only improve oxygenation, but also show obvious advantages in reducing inflammatory response. It is a safe and effective intraoperative ventilation strategy for elderly patients undergoing thoracoscopic radical resection of lung cancer.
ABSTRACT
ObjectiveTo explore the mechanism of Yishen Huoxue prescription in renal interstitial fibrosis （RIF） from the perspective of endothelial cell and cell energy metabolism. MethodThe model was successfully established by unilateral ureteral obstruction （UUO）. Seventy-five SPF C57BL/6 mice were randomly divided into a model group， a resveratrol group （50 mg·kg-1·d-1）， three Yishen Huoxue prescription low， medium， and high-dose groups （7.1， 14.2， 28.4 g·kg-1·d-1）， with 15 mice in each group. In addition， another 15 mice were used to prepare sham operation model. Mice in the sham operation group and the model group were gavaged with equal volume of normal saline. All mice were sacrificed on 7， 14， and 21 d after modeling. The protein expression of platelet endothelial cell adhesion molecule 31 （CD31） was detected by immunohistochemical S-P method. The expression of α-smooth muscle actin （α-SMA）， collagen Ⅳ （Col-Ⅳ）， angiopoietin 1（Ang-1） and tyrosine kinase receptors 2 （Tie-2）， vascular endothelial growth factor （VEGF）， vascular endothelial cadherin （VE-cadherin）， and occludin in renal tissues was detected by Western blotting. The mRNA expressions of Ang-1/Tie-2， VEGF， VE-cadherin， and occludin in renal tissues were detected by Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR）， and the levels of reactive oxygen species （ROS） in mice were detected by enzyme linked immunosorbent assay （ELISA）. ResultAs compared with the sham operation group， the expression of CD31 in renal tissues of the model group was significantly decreased and worsened with the extension of modeling time （P<0.05）， α-SAM and Col-Ⅳ protein expression levels were significantly increased （P<0.01）， but the expression of CD31 was stable in 14-21 d. ROS levels were significantly increased （P<0.01）， and the protein and mRNA expressions of Ang-1/Tie-2， VEGF， VE-cadherin， and occludin were significantly down-regulated （P<0.01）. As compared with the model group， the expression of CD31 was increased （P<0.05）， and α-SAM and Col-Ⅳ in the resveratrol group and the medium and high-dose Yishen Huoxue prescription groups were significantly decreased （P<0.01）. The ROS content was significantly decreased （P<0.01）， and the protein and mRNA expressions of Ang-1/Tie-2， VEGF， VE-cadherin， and occludin were up-regulated （P<0.01）， As compared with the resveratrol group， the protein expressions of Ang-1/Tie-2， VEGF， VE-cadherin， and occludin in the medium and low-dose Yishen Huoxue prescription groups were significantly different （P<0.01）. There was no significant difference in the mRNA expressions of CD31 and Ang-1/Tie-2 in the high-dose Yishen Huoxue prescription group， and no significant difference in the ROS level in the medium-dose Yishen Huoxue prescription group. ConclusionThe anti-RIF effect of Yishen Huoxue prescription may be related to promoting vascular endothelial repair， regulating mitochondrial ROS to reduce oxidative stress， protecting the integrity of renal endothelial structure， delaying cell apoptosis， and maintaining cell energy metabolism.
ABSTRACT
Two skeletally undescribed polyketide-indole hybrids (PIHs), named indolchromins A and B, were generated from indole-3-carbinol (I3C) in the fungal culture (). The indolchromin structures were elucidated mainly by their 1D and 2D NMR spectra with the former confirmed by the single-crystal X-ray crystallographic analysis. Each indolchromin alkaloid was chirally separated into four isomers, whose absolute configurations were assigned by comparing the recorded circular dichroism (CD) spectra with the electronic CD (ECD) curves computed for all optional stereoisomers. Furthermore, the indolchromin construction pathways in fungal culture were clarified through enzyme inhibition, precursor feeding experiment, and energy calculation. The cascade reactions, including decarboxylative Claisen condensation catalyzed by 8-amino-7-oxononanoate synthase (AONS), C()-H activation, double bond migration, and Michael addition, all undergone compatibly during the fungal cultivation. In an MIC range of 1.3-8.6 μmol/L, (2,4)- and (2,4)-indolchromin A and (2,4)-indolchromin B are inhibitory against , , sp., , and . (2,4)-Indolchromin A and (2,4)-indolchromin B were cytotoxic against the human breast cancer cell line MDA-MB-231 with IC values of 27.9 and 131.2 nmol/L, respectively, with the former additionally active against another human breast cancer cell line MCF-7 (IC 94.4 nmol/L).
ABSTRACT
Objective@#This study aims to explore the effect of lipid-induced macrophage M1/M2 polarization on lipid metabolism in hepatocytes.@*Methods@#RAW264.7 macrophages were incubated with different kinds of fatty acids including saturated fatty acids-palmitic acid (PA), monounsaturated fatty acids-oleic acid (OA) and polyunsaturated fatty acids-docosahexaenoic acid (DHA), and cell culture supernatants were collected to prepare conditioned medium (CM). Hepatocytes were isolated by in situ perfusion of the liver with collagenase in mice, and a macrophage-hepatocyte CM co-culture system was established. Macrophage M1/M2 phenotype markers were detected by Real-time PCR. Lipid synthesis and decomposition related mRNA and protein expressions in hepatocytes were detected by Real-time PCR and Western Blot. Lipid depositions in hepatocytes were detected by oil red O staining. An analysis of variance was used for comparison of means between multiple groups.@*Results@#Compared with control groups, PA polarized macrophages to a M1 phenotype (expression of TNF-α and IL-6 significantly increased, F≥22.68, P < 0.01), OA polarized macrophages to a M1/M2 mixed phenotype (expression of IL-6, Mrc2 and IL-10 increased F≥4.94, P < 0.05) and DHA polarized macrophages to a M2 phenotype (expression of Mrc2 and IL-10 significantly increased, F≥4.94, P < 0.01). CM-PA significantly increased lipid synthesis related genes, including SREBP1C, ACC1 mRNA expression (F≥5.66, P < 0.01) and FASN, ACC1 protein expression (F≥38.34, P < 0.05) in hepatocytes, and decreased lipid decomposition gene ACOX1 protein expression (F=154.48, P < 0.01). CM-OA affected several lipid metabolism genes expression. CM-DHA significantly increased CPT1A mRNA expression (F = 10.30, P < 0.01) and ACOX1, CPT1A protein expression (F≥47.06, P < 0.05), and decreased SREBP1C, ACC1 protein expression (F≥65.84, P < 0.05) in hepatocytes. Massive lipid droplets were deposited in hepatocytes in CM-PA treated hepatocytes, and a few amount of lipid droplets were deposited in CM-DHA treated hepatocytes.@*Conclusion@#Different fatty acids affect the balance of lipid metabolism in hepatocytes and liver by inducing macrophage M1 / M2 polarization, thus promoting or delaying the progression of non-alcoholic fatty liver disease.
ABSTRACT
Background:Kupffer cells and hepatic stellate cells(HSC)play important roles in the initiation and progression of hepatic inflammation and fibrosis in chronic liver injury. Aims:To investigate the roles of Kupffer cell polarization and HSC activation in the development of hepatic inflammation and fibrosis in progression of non-alcoholic fatty liver disease (NAFLD). Methods:C57BL/6 mice were fed with high fat(HF)diet and methionine-choline-deficient(MCD)diet to induce experimental non-alcoholic fatty liver(NAFL)and non-alcoholic steatohepatitis(NASH),respectively. Liver steatosis,inflammation and fibrosis were determined by histopathological examination through HE staining and Masson staining. Kupffer cell phenotypes and HSC activation were assessed by immunohistochemistry. Expressions of PPAR-γ as well as inflammation-and fibrosis-related genes were measured by real-time PCR. Results:F4/80-positive Kupffer cells, CD11c-positive M1 polarized macrophages and α-SMA-positive HSC were significantly increased in liver tissue of mice with HF diet-induced NAFL and MCD diet-induced NASH(P<0.05),and was more apparent in MCD diet-induced NASH (P<0.05). Expressions of TNF-α and TGF-β1 mRNA in liver tissue were significantly increased in both groups(P<0.05),whereas expressions of α-SMA and Col1 mRNA were significantly increased only in NASH(P<0.05). Hepatic PPAR-γ mRNA expression was significantly increased in NAFL(P<0.05)but significantly decreased in NASH(P<0.05). Conclusions:Hepatic Kupffer cells exists a sustained M1 polarization in the development of NAFLD. Activation of HSC appears in the early stage of NAFLD,and accelerates in the progression of NAFL to NASH. Polarization of Kupffer cells and activation of HSC initiate and promote hepatic inflammation and fibrosis in NAFLD.

ABSTRACT
Objective To investigate the risk factors of pneumonia associated to elderly patients with cerebral stroke.Methods Totally 248 elderly patients with stroke were retrospectively analyzed on medical history,treatment and prognosis.Results In 248 cases of senile stroke patients,78 cases had an associated pneumonia,accounting for 31.5％.The onset with admission period ≥48 h was in majority (48 cases),less than 48 h in 30 cases (38.5％).12 patients (15.4％)were involved blood culture,38 cases sputum culture,accounting for 48.7％.In the univariate correlation analysis,older age,consciousness,basic diseases,stroke location,NIHSS score of nasal feeding therapy were associated with associated pneumonia (all P＜0.05).As compared to patients without no associated pneumonia,the patients with associated pneumonia had more aged and higher proportions of bulbar paralysis and impaired consciousness,more underlying diseases.At the time of admission,increased occurrences of National Institute of Health Stroke Scale (NIHSS) score,brainstem stroke and multiple feeding treatment appeared in most of patients.Multivariate Logtistic regression analysis showed that age≥ 65 years,history of pulmonary disease,bulbar paralysis,disturbance of consciousness,nasal treatment among older stroke were the associated pneumonia risk factors.The hospitalized time was prolonged [(31.3±20.4)d and(17.6±8.1)d,t＝7.57,P＝0.001] and fatality rate increased (41.0％ vs.4.1％) in patients with pneumonia than without pneumonia(x2＝ 54.96,P＝ 0.000).The independent factors of death were aged ≥ 75 years(OR＝1.6,95％CI:1.0-2.6),NIHSS＞13 (OR＝5.0,95％CI:1.7-24.6) and pulmonary infection(OR＝5.2,95％ CI:1.8-17.3).Conclusions The occurrence of associated pneumonia in elderly patients with cerebral stroke is related with age,underlying disease,state of consciousness and NIHSS scores.The prevention and treatment of relevant factors can improve prognosis.
ABSTRACT
BACKGROUND:Articular capsule ligaments can lead articular surface to move normally and limit the excessive movement, especially to prevent any non-physiological movement. They are the important structures for stabilizing hip joints. It was previously thought that articular capsule should be routinely resected in the total hip arthroplasty (THA). OBJECTIVE: This study was designed to investigate the effect of retaining articular capsule in THA through posterior approach on maintaining hip stability. DESIGN, TIME AND SETTING: This study, a retrospective case analysis, was performed on 61 patients with femoral neck fracture, who received treatment in the Department of Orthopedics, Xiangya Second Hospital of Central South between January 2005 and December 2006. PARTICIPANTS: Twenty-nine patients who underwent THA with retaining articular capsule from January to December 2006 were included as retaining group, and thirty-two patients who underwent THA with routine resection of partial articular capsule were included as routine group. The two groups were kept identical in case selection, prosthesis selection, post-surgery processing and operators. METHODS: Four holes were drilled on greater trochanter on the proximal femoral bone. The superior part of articular capsule valve was sutured to the superior part of original articular capsule using No.1-0 absorbing thread, then sutured to base of femoral neck in mattress manner, and the suture was not ligated. The inferior part of articular capsule valve was sutured to the inferior part of original articular capsule using another suture. And the suture passed through two bone holes on base of femoral neck. The lower limbs were externally rotated and the suture was ligated. Subsequently, the excised extortor was repaired. Prior to and subsequent to suture, hip was slowly bent for 90° and femur was internally rotated for45°to investigate the suture of articular capsule on strengthening articular stability. MAI OUTCOME MEASURES: Operation time, bleeding volume and hip dislocation after THA. RESULTS: The operation time and bleeding volume were lower in the retaining group than in the routine group (P < 0.05). After THA, hip dislocation did not occur in any patients in the retaining group but occur in 2 patients (6.2%) in the routine group. Statistical tests could not be performed due to less data, resulting in no statistical significance.CONCLUSION: There has been no precise conclusion about the effects of retaining articular capsule or not on hip stability.But retaining articular capsule shortens operation time, reduces intrao-perative bleeding, unable raise operation risk, and re-establishes hip soft tissue balance.
