Objective:To explore the effect of Bian-stone warming and ironing therapy on gastrointestinal blood flow in patients with severe cerebrovascular disease undergoing therapeutic hypothermia.Methods:From January 2023 to October 2024, 92 patients with severe cerebrovascular disease in the Neurosurgical Intensive Care Unit of Xuanwu Hospital of Capital Medical University were selected for the study using convenience sampling method. The patients were divided into a control group and an experimental group of 46 cases each according to the randomized numerical table method. Control group was given routine nursing, and experimental group carried out Bian-stone warming and ironing therapy on the basis of control group. Peak systolic velocity (PSV), end-diastolic velocity (EDV), and time-averaged mean velocity (TAMV) of the superior mesenteric artery of the two groups of patients were monitored before and after five days of intervention, respectively, and the situation of gastric retention and bowel sounds were recorded and compared between the groups.Results:PSV was higher in experimental group than in control group after intervention, and the difference was statistically significant ( P<0.05). The difference in EDV between the two groups was not statistically significant ( P>0.05). TAMV of experimental group was higher than that of control group after intervention, and the difference in TAVM before and after intervention of experimental group was smaller than that of control group, and the differences were all statistically significant ( P<0.05). The number of cases of gastric retention and weakened or disappeared bowel sounds in experimental group was less than that in control group after intervention, and the differences were all statistically significant ( P<0.05) . Conclusions:Bian-stone warming and ironing therapy improves gastrointestinal blood flow rate and reduces feeding intolerance in patients with severe cerebrovascular disease undergoing therapeutic hypothermia.

BACKGROUND:Osteoporotic vertebral compression fracture is a common fracture secondary to osteoporosis.At present,there is no effective prediction index and method for osteoporotic vertebral compression fracture. OBJECTIVE:To investigate the predictive effect of the comprehensive index of lumbar vertebral body bone strength on osteoporotic vertebral compression fracture. METHODS:233 patients with osteoporosis were divided into a fracture group and a non-fracture group according to whether a vertebral fracture occurred.The demography,body mass index,vertebral bone mineral density and other details were collected.Lateral X-ray films of the lumbar spine were photographed.The vertebral body width,vertebral body length,sacral slope,pelvic tilt,pelvic incidence,lumbar compressive strength index and the lumbar impact strength index were measured,calculated,and analyzed by univariate and multivariate,and the receiver operating characteristic curve was analyzed.The survival analysis was conducted according to the cut-off value. RESULTS AND CONCLUSION:(1)All patients were followed up for 2-4 years,with an average of 3.1 years.During the follow-up period,99 cases(38 cases of L1 vertebral body,61 cases of L2 vertebral body)had fractures(fracture group),and 134 cases(52 cases of L1 vertebral body,82 cases of L2 vertebral body)had no fractures(non-fracture group).Univariate analysis showed that there was no significant difference in age,sex,height,body mass,body mass index and fracture segment between the two groups(P>0.05).(2)Lumbar compressive strength index and lumbar impact strength index in the fracture group were lower than those in the non-fracture group(P<0.05).Pelvic incidence and pelvic tilt in the fracture group were higher than those in the non-fracture group(P<0.05).(3)Multivariate analysis showed that lumbar compressive strength index,lumbar impact strength index and pelvic tilt were risk factors for osteoporotic vertebral compression fractures(P<0.05).(4)Receiver operating characteristic curve analysis showed that the cutoff values of vertebral bone mineral density,lumbar compressive strength index,lumbar impact strength index,pelvic tilt and pelvic incidence were 0.913 5 g/cm2,1.932,0.903,21.5° and 55°,respectively;areas under the curve were 0.630,0.800,0.911,0.633 and 0.568,respectively.(5)According to the survival analysis(with osteoporotic vertebral compression fracture as the end point),the average survival time of the patients with lumbar impact strength index≥0.903 was significantly longer than that of the patients with lumbar impact strength index<0.903(P<0.05).(6)These findings conclude that the comprehensive index of lumbar vertebral body bone strength is more accurate than the bone mineral density of the vertebral body and spine-pelvis sagittal parameters in predicting osteoporotic vertebral compression fractures,which is helpful for early prevention and treatment of osteoporotic vertebral compression fractures.

BACKGROUND:Osteoporosis vertebral compression fracture is a common fracture secondary to osteoporosis,and there is currently a lack of effective predictive indicators and methods for osteoporosis vertebral compression fracture. OBJECTIVE:To investigate the predictive effects of paravertebral muscle degeneration,functional cross-sectional area,and percentage of fat infiltration on osteoporotic vertebral compression fractures. METHODS:The 224 patients with osteoporosis diagnosed from January 2018 to June 2022 were included.They were followed up for more than 2 years.They were divided into fracture group and non-fracture group according to the presence and absence of vertebral fracture.The detailed information of demographics,body mass index,bone mineral density and so on were collected.The functional cross-sectional area and percentage of fat infiltration of bilateral Psoas major muscle and extensor dorsi(Erector spinae muscles muscle and multifidus muscle)at the level of lower endplate of L2 vertebral body were measured and calculated. RESULTS AND CONCLUSION:(1)224 patients were ultimately included,of which 126 had fractures as the fracture group and 98 had no fractures as the non-fracture group.There was no statistically significant difference in age,gender,height,body mass,body mass index,and fracture segment between the two groups(P>0.05).(2)The bone mineral density of the fracture group was significantly lower than that of the non-fracture group(P<0.05).Functional cross-sectional areas of Psoas major muscle and extensor dorsi in the fracture group were significantly lower than those in the non-fracture group(P<0.05).The percentage of fat infiltration of the extensor dorsi in the fracture group was significantly higher than that in the non-fracture group(P<0.05).There was no significant difference in percentage of fat infiltration of Psoas major muscle between the two groups(P>0.05).(3)Receiver operating characteristic analysis showed that the vertebral bone mineral density,percentage of fat infiltration of extensor dorsi,functional cross-sectional area of extensor dorsi and percentage of fat infiltration of Psoas major muscle were 0.903 g/cm2,35.426%,418.875 mm2,and 6.375%,respectively.The areas under curve were 0.634,0.755,0.876,and 0.585,respectively.(4)These findings indicate that paravertebral muscle degeneration is strongly associated with the occurrence of osteoporotic vertebral compression fractures.The functional cross-sectional area of extensor dorsi muscle can effectively predict the occurrence of osteoporotic vertebral compression fractures,which is helpful for early prevention and treatment of osteoporotic vertebral compression fractures.

Primary liver cancer (hereinafter referred to as HCC) is the sixth most common type of cancer and the third leading cause of cancer-related mortality worldwide. Since patients in the early stage of HCC are typically asymptomatic and there are currently no specific detection methods for the early stage of HCC, the majority of patients are diagnosed in the late stage. Exosomes carry proteins, non-coding RNAs, such as cyclic RNAs (circRNAs), and other biological molecules. Patients with hepatocellular carcinoma have a higher concentration of serum exosomes than healthy individuals, and the circRNAs in the exosomes can reflect the source cells and real-time disease status, suggesting it has the potential to detect liver cancer early. This paper focuses on the latest progress of exosomal circRNAs and analyzes the potential value of exosomes in the early diagnosis, treatment, and progression of HCC.
