ObjectiveTo divide the muscle into different subzones according to different density ranges using the stratified analysis on the basis of myosteatosis， and to investigate the effect of muscle density changes on complications （Clavien-Dindo grade ≥Ⅲ） after orthotopic liver transplantation （OLT）. MethodsA retrospective analysis was performed for the medical records of 145 patients who underwent OLT in The First Hospital of Jilin University from May 2013 to September 2020， and with the plain CT scan images of the largest level of lumbar 3 vertebrae of each patient as the original data， Neusoft Fatanalysis software was used to measure related muscle parameters. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. The chi-square test or Fisher test was for comparison of categorical data between two groups. RIAS software was used to extract clinical features and perform analysis and modeling， and three machine learning models of logistic regression （LR）， support vector machine （SVM）， and random forest （RFC） were constructed. The receiver operating characteristic （ROC） curve， the calibration curve， and the decision curve were plotted for each model to calculate the area under the ROC curve （AUC）， sensitivity， specificity， precision， F1 score， and accuracy. ResultsThe three machine learning models of LR-C， SVM-C， and RFC-C were established based on the 7 clinical features before muscle stratification analysis， among which the RFC-C model had an AUC of 0.803， a sensitivity of 0.588， and a specificity of 0.778 in the test set. Among the models of LR-CS， SVM-CS， and RFC-CS established based on the 16 clinical features after muscle stratification analysis， the LR-CS and SVM-CS models had an AUC of 0.852 in the test set， with a sensitivity of 0.765 and 0.706， respectively， and a specificity of 0.889 and 0.926， respectively. Comparison of the AUC， sensitivity， specificity， precision， F1 score， and accuracy of each model in the test set before and after muscle stratification analysis showed that there were improvements in the parameters of the predictive model after muscle stratification analysis. Comparison of the decision curves and calibration curves of each predictive model showed that the LR-CS and SVM-CS models had good efficacy in predicting postoperative complications （Clavien-Dindo grade≥Ⅲ） in OLT patients. ConclusionOn the basis of myosteatosis， the division of the muscle into different subzones according to different densities using the stratified analysis has a certain value in predicting postoperative complications in patients with OLT.

It is believed that the head and facial orifices are connected with the brain's spirit and the spirits of the five organs. Their functions， including vision， hearing， smell， taste， and speech， are manifestations of the activity of the spirit. Furthermore， head and facial orifice disorders are interrelated with spirit disorders， forming a cause-and-effect relationship. Acupuncture has a regulatory effect on the spirit. Based on this， acupuncture for regulating the spirit in treating head and facial orifice disorders is proposed. This includes regulating the brain's spirit to treat functional disorders， regulating the heart's spirit to clarify the functions of governing substances， regulating the organ's spirit to benefit the orifices and enhance the communication of the spirit， and regulating the liver's spirit to promote the flow of Qi （气） and relieve stagnation， thereby providing a framework for acupuncture to treat head and facial orifice disorders.

It is regarded that the disease location of refractory facial paralysis is in the channel sinews of the face， with its primary pathogenesis characterized by a combination of deficiency and stasis of the channel sinews. The integration of repeated shallow needling method and fire acupuncture can first remove stagnation within the channel sinews， and second utilize the warming effect of fire to reinforce yang， stimulate meridian qi， and nourish the channel sinews. This approach balances both supplementation and drainage manipulation， aligning with the underlying pathogenesis of deficiency and stasis combination. In clinical practice， diagnostic methods should be applied flexibly to accurately identify the affected channel sinews. The severity of facial symptoms， the size and mobility of the paralyzed facial muscles， as well as the depth and size of the reactive points identified through palpation， should be considered when determining the extent of the condition. By adjusting the appropriate level of stimulation， the fire acupuncture with repeated shallow needling method could effectively improve facial muscle morphology and function， promoting recovery from the disease.

Monotropein is a compound classified into iridoid which is found in herbaceous plants Morindae officinalis. It possesses anti-inflammatory, antioxidant, and anti-osteoarthritic activities. Previous study indicates that monotropein may have the potential to combat cardiovascular disease, although the related mechanism remains unclear. In this study, we constructed the model of atherosclerosis by oxidized low density lipoprotein-induced vascular smooth muscle cells and LDLR –/–mice given high-fat diet to investigate the effects of monotropein on atherosclerosis.Our results showed that monotropein treatment significantly reduced the area of atherosclerotic plaques and necrotic cores in mice, inhibited the proliferation and migration of vascular smooth muscle cells, and reduced inflammatory responses and oxidative stress, which in turn alleviated atherosclerosis. In addition, we found that monotropein reduced the expression levels of P-NF-κB and P-AP-1. In conclusion, our data suggest that monotropein inhibited the proliferation and migration of vascular smooth muscle cells by mediating the activity of NF-κB, AP-1, reducing the level of inflammation and oxidative stress, and thus resisting the development of atherosclerosis. These findings demonstrate the efficacious therapeutic impact of monotropein on atherosclerosis and elucidate its specific target.

By systematically sorting out the theoretical origin， manipulation key points， and clinical applications of sparrow-pecking needling， it is believed that sparrow-pecking needling method involves performing small-amplitude， high-frequency lifting and thrusting of the needle tip in the original position， with heavy thrusting and light lifting， starting slowly and then becoming rapid， thus forming a characteristic needling sensation that spreads to the surroundings in a wavelike manner. The sparrow-pecking needling plays a role in stimulating the conduction of channel qi and regulating the circulation of qi and blood. Additionally， this paper summarized the clinical applications of sparrow-pecking needling in five aspects， regulating mind， regulating channel sinews， regulating zang-fu organs， regulating ying-wei （nutrient and defense qi）， and regulating yang qi， so as to provide references for inheriting and expanding the theory and clinical application of sparrow-pecking needling.

Objective To explore the clinical effect and safety of remimazolam combined with alfentanil in painless gastroenteroscopy in elderly patients.Methods 188 elderly patients who were scheduled to undergo painless gastroenteroscopy from October 2021 to February 2023 were selected and divided into group A,group B,group C,and group D by random number table method,with 47 cases in each group.The group A,group B and group C were used remimazolam 0.2,0.3 and 0.4 mg/kg,and alfentanil 3 μg/kg respectively,and the remimazolam 2.5 mg/time was added during the operation.The group D was used propofol 1.5 mg/kg and alfentanil 3 μg/kg,and a single dose of propofol 0.5 mg/kg was added during the operation.The hemodynamics at different time points[3 min before anesthesia administration(T0),immediately after endoscopy(T1),3 min after endoscopy(T2),at the end of examination(T3),at the time of awakening(T4)],anesthesia onset time,sedation success rate,gastrointestinal endoscopy time,awakening time,time to leave the observation room and intraoperative/postoperative complications were compared,and the test results of neurobehavioral cognitive state examination(NCSE)were compared at different times.Results The percutaneous arterial oxygen saturation(SpO2)at T1 and T2 time point were higher than group C and group D,and the differences were statistically significant(P<0.05).There was no statistically significant difference in the heart rate(HR)and mean arterial pressure(MAP)among group A,group B,group C and group D at each time point(P>0.05).There was no statistically significant difference in SpO2 between group A and group B at each time point(P>0.05).There was no statistically significant difference in the success rate of sedation,gastrointestinal endoscopy examination time and time of leaving the observation room among the four groups(P>0.05),but the onset time of anesthesia in group A was longer than that in group B,group C and group D,and the awakening time in group A and group B was shorter than that in group C and group D,and the differences were statistically significant(P<0.05).There was no statistically significant difference in awakening time between group A and group B(P>0.05).The incidence rate of bradycardia in group A and group B was lower than in group D,and the incidence rates of hypoxemia,respiratory depression,hypotension,and dizziness in group A were lower than those in group D,and the incidence rate of injection pain in group A,group B and group C was lower than that in group D,and the differences were statistically significant(P<0.05).After 10 minutes of complete wakefulness,there was no statistically significant difference in the passing rates of calculation ability and the memory tests between group A and group B(P>0.05),but the passing rates of calculation ability and memory test in group A were higher than those in group C and group D,and the differences were statistically significant(P<0.05).Conclusion During painless gastroenteroscopy in elderly patients,the sedative effect of using 0.3 mg/kg remimazolam combined with alfentanil is good,and it has stable hemodynamics,and the occurrence rate of complications such as bradycardia and espiratory depression is low,and the early postoperative cognitive function is recovered well.
