Effects of combinedintravenous and inhalation anesthesia on immune function and cognitive function in postoperative cirrhotic patients with a background in athletics and fitness

Objective: To evaluate the effects of combined intravenous and inhalation anesthesia on postoperative immune and cognitive function in cirrhotic patients, particularly those with a background in athletics and fitness. Methods: A systematic literature search was conducted in the Cochrane Library, Web of Science, PubMed, ProQuest, and Chinese biomedical literature databases (Wanfang, Weipu, CNKI) for controlled trials assessing combined intravenous and inhalation anesthesia in cirrhotic patients, with an emphasis on those maintaining an athletic or fitness-oriented lifestyle. The literature was analyzed using RevMan 5.3 software, focusing on exploring the heterogeneity of the studies. Results: Nine research papers were included in the meta-analysis, encompassing a total of 775 subjects, including 382 in the control group and 393 in the experimental group. Among these, a significant portion of the subjects were identified as being involved in regular athletic or fitness activities. Eight papers were prospective studies, and one was retrospective. The meta[1]analysis revealed that combined intravenous and inhalation anesthesia significantly increased CD3+, CD4+, and CD8+ levels, and improved the CD4+/CD8+ ratio, demonstrating enhanced immune function. Additionally, cognitive function improvements were noted [OR: 1.45, 95% CI (1.03, 1.87), P<0.00001]. There were also significant improvements in liver function markers ALT and ALB.

Analysis of the therapeutic effect and prognosis in 86 cases of rib fractures and atelectasis.

BACKGROUND: The aim of the present study was to explore the therapeutic effect and prognosis in patients with rib fractures and atelectasis after thoracic trauma in order to provide a basis for clinical decision-making in primary hospitals. METHODS: A retrospective study was conducted on 86 patients admitted to our hospital between January 2016 and May 2020 with rib fractures and atelectasis after thoracic trauma. On the basis of the chest computed tomography scans taken at the time of discharge, the patients were divided into two groups: the reexpansion group and the non-reexpansion group. The two groups were compared with respect to the changes observed in the patients' levels of blood oxygen saturation (SpO2) and pulmonary function, the presence of secondary pulmonary or thoracic infection, the time of chest tube drainage, the length of hospitalization, the cost of hospitalization, and the patients' level of satisfaction with their quality of life 3 months after discharge. RESULTS: In the reexpansion group, there were significant differences in the levels of SpO2 and pulmonary function measured before and after pulmonary reexpansion (P < 0.05). Compared with the non-reexpansion group, the patients in the reexpansion group had a lower incidence of secondary pulmonary and thoracic infection and a higher level of satisfaction with their quality of life after discharge; these differences were statistically significant (P < 0.05). There was no statistical significance between the two groups with respect to the time of chest tube drainage or the length of hospitalization (P > 0.05). However, the cost of hospitalization was significantly higher in the reexpansion group than in the non-reexpansion group (P < 0.05). CONCLUSIONS: The patients in the pulmonary reexpansion group had a lower incidence of complications and a better prognosis than the patients in the non-reexpansion group.

Data on the anisotropic interfacial slip length over fibrous porous media.

To characterize the velocity slip at the fibrous porous media, data on the anisotropic slip length has been fully analyzed through direct simulations for various geometrical aspects of fiber architecture [2] ). This data article provides detailed slip lengths and slip coefficients in dimensionless form as a function of various geometrical parameters of fibrous porous media including the fiber volume fraction, the dimensionless void length and the normalized permeability. The data is presented for three different fiber packing structures (the quadrilateral, hexagonal and compressed hexagonal packing) in both the fiber and normal to fiber directions. Finally a set of curves from the complete fitted equation set are also provided in a single figure that can be used to estimate the slip length and the normalized permeability for a given fibrous porous media.

[Pollution characteristics and sources of polycyclic aromatic hydrocarbons in urban rivers of Wenzhou city].

Concentrations of 18 polycyclic aromatic hydrocarbons (PAHs) in water and surface sediments collected from the urban rivers of Wenzhou city in spring and summer were measured by GC-MS. The results showed that the total PAHs concentrations in water and sediments of the studied rivers varied in ranges of 146.74-3 047.89 ng x L(-1) and 21.01-11 990.48 ng x g(-1), respectively. Higher concentrations occurred in spring. The low and middle rings of 2-4-ring were dominant in both water and sediments, but the concentrations of 5-ring and 6-ring PAHs in sediments were relatively higher than those in water. The EBaP values of PAHs in water of the studied rivers in spring and summer were 1.69-51.95 ng x L(-1) and 0-3.03 ng x L(-1), respectively. Eighty percent of water samples in spring surpassed the limits of BaP in surface water of China. The concentrations of sigma PAHs in the sediments both in spring and summer were lower than the ERM value, but part of the components of PAHs had values higher than the ERM, suggesting possible toxic effect on living organisms. Based on the PAHs molecule ratios and principal component analysis, a mixed PAHs source of petroleum and combustion in water and sediments was diagnosed, while sediments showed a greater proportion of combustion sources.

[Distribution and ecological risk assessment of polycyclic aromatic hydrocarbons in agricultural soil of the Chongming Island in Shanghai].

The concentration and ecological risk of Polycyclic aromatic hydrocarbons (PAHs) were investigated in thirty-three surface soil samples collected from cultivated land in Chongming Island in July 2008. Those samples were extracted using an accelerated solvent extractor (ASE) and determined by GC-MS. Results showed that the concentrations of PAHs ranged between 24.92-1014.61 ng x g(-1) (dry weight), with a mean value of 192.83 ng x g(-1). The sixteen priority PAHs with exception of Indeno(1, 2, 3-cd) pyrene (IcdP) and Dibenzo(a, h)anthracene (DahA) were all detected in all the samples. The dominant compounds were 2-3 ring and 4 ring PAHs, which accounted for 42.6% and 42.2%, respectively, while the 5-6 ring PAHs accounted for 15.7%. PAHs in soil were mainly derived from the fossil oil and the combustion of wood and coal, as determined by the concentration ratio method. The non-industrial combustion and automobile exhaust emissions in Chongming Island may be two of the important sources of PAHs in farmland soil. The analysis of ecological risk showed that the agricultural soil of Chongming Island had low ecological risk.

[Laboratory simulation study on the influence of resuspension on the release of mercury from Yangtze estuarine tidal flat].

Using a Particle Environment Simulator, laboratory simulation experiment on the influence of resuspension on the release of mercury from sediments collected from medium tidal flat and low tidal flat in Chongming Dongtan was conducted. Results indicated that the conditions of overlying water changed significantly during resuspension. The concentrations of HgD and HgP were mainly in the rang of 0.152-2.657 microg x L(-1), 0.080-2.722 microg x L(-1) separately. In the resuspension processes, mercury was released from the medium intertidal sediments under the salinity condition of 4.1 per thousand, 8.0 per thousand, 10.0 per thousand, 13.0 per thousand, and from the low intertidal sediments under the salinity condition of 13.0 per thousand. However, the release of mercury from the medium intertidal sediments is not significant under the salinity condition of 4.1 per thousand, 8.0 per thousand, 10.0 per thousand. The salinity of overlying water had an important effect on resuspension. In different salinity condition, the release of mercury was different. And the release of mercury from medium tidal flat and low tidal flat was different during the resuspension periods, the release of mercury from the medium intertidal sediment was significantly higher than the release from the low intertidal sediment. When the rotate speed was (210 +/- 5) r x min(-1), the desorption of mercury significantly increased, thereby the rotate speed had an effect on the release of mercury.

[Characteristics of organochlorine pesticide residues in agricultural soil of Chongming Island in Shanghai].

Thirty surface soil samples were collected to investigate the residue concentrations of organochlorine pesticides (OCPs) in agricultural soil of Chongming Island in July 2008. Those samples were extracted using accelerated solvent extraction (ASE) and determined by gas chromatography with an electron capture detector (GC-microECD). Results showed that the concentrations of OCPs (dry weight) ranged between 3.11-117.47 ng x g(-1), with mean value of 26.25 ng x g(-1). Two major contaminants of OCPs were DDTs and HCHs, the concentration of which varied from 0.14 ng x g(-1) to 77.89 ng x g(-1) and from 1.14 ng x g(-1) to 22.43 ng x g(-1), respectively. At the same times, hexachlorobenzene (0.23-11.63 ng x g(-1)), aldrin (0.03-0.75 ng x g(-1)), heptachlor epoxide (0.05-1.44 ng x g(-1)), dieldrin (0.05-5.33 ng x g(-1)), endrin (ND-14.66 ng x g(-1)) and mirex (0.03-10.58 ng x g(-1)) could also be detected. Most of DDTs had been degraded to DDD and DDE, with the major compounds of DDE (about 64.7%), and the recent existed DDT was the residue of early input. All of the four isomers of HCHs were detected, and the contents of alpha-HCH (about 48.1%) and beta-HCH (about 33.4%) were the maximum. The highest OCPs residues appeared in the soil of farm cultivation compared to greenhouse cultivation and ordinary open-air cultivation.
