ABSTRACT
Myosteatosis is the main manifestation of malnutrition and is a common complication of chronic liver diseases, with a negative impact on the progression and prognosis of liver diseases. There is no gold standard for the diagnosis of myosteatosis, and CT is a commonly used diagnostic method. Myosteatosis in chronic liver diseases has diverse mechanisms, and hyperammonemia, increased cathepsin D level in circulation, insulin resistance, mitochondrial dysfunction, and chronic systemic microinflammation play an important role in myosteatosis. Early intervention of these factors can improve prognosis. With reference to related studies in China and globally, this article reviews the features, diagnostic methods, pathogenesis, treatment, and intervention of myosteatosis.
ABSTRACT
Objective:To explore the risk factors of sarcopenia in liver cirrhosis and construct a diagnosis model for sarcopenia in cirrhosis.Methods:73 patients with liver cirrhosis hospitalized in Department of Gastroenterology of Shanxi Provincial People's Hospital between June 2021 and June 2022 were included. Common measurements in liver cirrhosis and abdominal CT scans of all patients were collected. The cross-sectional area of skeletal muscle at L3 level was calculated by sliceomatic and the skeletal muscle index (SMI) was subsequently obtained by height standardization. The patients were divided into sarcopenia group and non-sarcopenia group using Asian cut-off per European Working Group on Sarcopenia in Older People-2nd meeting (EWGSOP2) criteria. Risk factors related to sarcopenia in cirrhosis were analyzed and a subsequent diagnosis model was established.Results:among the cirrhotic patients included in the study, the prevalence of sarcopenia was 65.75% (48/73), 47.73% (21/44) in males and 93.10% (27/29) in females, respectively. There were significant differences in age, sex, BMI, liver function grade per Child Pugh classification, etiology, ferritin level, prothrombin time and hemoglobin level between sarcopenia and non-sarcopenia groups (P < 0.05). Age, liver function, sex and ferritin level were closely related to the occurrence of sarcopenia in cirrhosis. A diagnostic model was developed based on these 4 indexes and the area under curve reached up to 95.7%.Conclusion:≥ 60 years old, female, Child-Pugh C grade and ferritin < 29.60 μg/L are independent risk factors for sarcopenia in cirrhosis and the model with these indexes shows good diagnostic value for sarcopenia in cirrhosis.
ABSTRACT
Objective To investigate changes in intestinal bacteria in chronic renal failure (CRF),their diagnostic value for CRF,and correlations between specific bacterial genera and renal function.Methods Fecal specimens were collected from 56 patients with CRF and 38 healthy controls in the Nephrology Department and Medical Examination Center of Shanxi People's Hospital between August 2017 and January 2018.High-throughput sequencing analysis of 16S rDNA V3-V4 hypervariable regions was performed for intestinal bacteria.Intestinal bacteria in CRF patients and healthy subjects were analyzed for alpha,beta diversity,species composition analysis,and differential species analysis.The diagnostic value of the presence of specific intestinal bacteria for CRF was analyzed using a receiver operating characteristic curve (ROC).Pearson's correlation analysis was used to analyze the correlation between the presence of specific genera and the estimated glomerular filtration rate (eGFR).Results The alpha and beta diversity in the CRF group was different from that in the control group (P ＜ 0.05).At the phylum level,Verrucomicrobia were significantly less abundant in the CRF group than that in the control group (0.70％ vs 3.09％,P ＜ 0.001).The abundance of Actinobacteria was significantly greater in the CRF group than that in the control group (1.48％ vs 1.14％,P=0.036).At the genus level,the abundance of Akkermansia (0.96％ vs 3.90％),Parasutterella (0.47％ vs 0.93％),and Lactobacillus (0.07％ vs 0.48％) in the CRF group was significantly less than those in the control group (all P ＜ 0.01).The abundance of Alloprevotella (0.41％ vs 0.04％) and Clostridium Ⅳ (0.6％ vs 0.1％) was significantly greater than those in the control group (all P ＜ 0.05).The diagnostic value of CRF for the area under the ROC curve (AUC) for Akkermansia was 0.753,and that for Lactobacillus diagnostic value of CRF was 0.792.The combined AUC diagnostic value of CRF for detection of Akkermansia and Lactobacillus was 0.830,with high disease prediction value.Lactobacillus abundance was positively correlated with eGFR (R=0.29,P=0.029).Conclusions The diversity and structure of intestinal bacteria are altered in patients with CRF.The abundance of Akkermansia and Lactobacillus has diagnostic value for CRF.The abundance of Lactobacillus is positively correlated with eGFR.

ABSTRACT
Objective To explore a method to prepare a model of renal ischemia-reperfusion injury, with mild injury to animals, simple and easy to operate and stable effectiveness. Methods Healthy SD male rats were randomly divided into normal group (group C), sham-operated group (group S) and experimental group (IR group). Rats in the experimental group received a median incision in the middle of the back skin. Through the muscle fascia of each side on the back into the bilateral retroperitoneal space, the bilateral renal pedicles were separated, and closed for 50 min with a mini artery clamp without injury, and then the blood perfusion of the bilateral renal pedicles was resumed by releasing the mini artery clamp. Except that the rats of sham operation group were not blocked the renal pedicle, the rest of the operating steps were consistent with the experimental group. The normal group rats were not treated except for anesthesia. To observe the condition of the rats, serum creatinine (SCr), blood urea nitrogen (BUN) and pathologyical changes in the kidney tissues at 24 h after operating. Results Skin incision was 2. 24 ± 0. 27 cm in the group IR, the right incision of lumbar dorsal fascia and muscle was 1. 36 ± 0. 21 cm, and the left incision was 1. 36 ± 0. 24 cm. The operation time was 3. 30 ± 0. 37 min from incising skin to clamping the bilateral kidney pedicles. The successful rate of model preparation reached 95% in the IR group. Compared with the groups C and S, the levels of SCr and BUN were remarkably increased in the IR group (P ＜0. 01), and renal tubular necrosis scores were also significantly increased (P＜ 0. 05). Conclusions The rat model of renal ischemia-reperfusion injury is established by clamping bilateral renal pedicles via dorsal retroperitoneal incision. This surgical procedure is stable and simple, with a high success rate and small incision, less bleeding, and minimal animal injury.

ABSTRACT
We investigated the plant regeneration and production of flavonoids in three high-yield flavonoids transgenic Saussurea involucrata hairy roots C17, C27 and C46 by quantification of two phytohormones GA3 and IAA. The results showed that GA3 concentration at more than 1.0 mg/L could induce adventitious shoots in the hairy root lines. The highest shoot regeneration rate, about 82%, was obtained when the hairy roots C17 were cultured with 2.0 mg/L GA3. The results on HPLC and UV spectrophotometry showed that exogenous application of both GA3 and IAA increased the content of flavonoids in the hairy roots. The contents of flavonoids and apigenin in the hormone-treated hairy roots and regenerates were higher comparing with those in the untreated hairy roots and the regenerates. However, the content of flavonoids was not related to tissue weight, and was negatively related to the regeneration efficiency.
