OBJECTIVE To investigate the effects and mechanisms of Buyang huanwu decoction （BYHWD） and its active fractions in ameliorating non-alcoholic fatty liver disease. METHODS BYHWD and its effective fractions obtained through ethanol precipitation， as well as 30% ethanol， 50% ethanol， and 75% ethanol fractions （namely， the CC effective fraction， 30YC effective fraction， 50YC effective fraction， and 75YC effective fraction）， were prepared. These preparations were administered to rats via intragastric administration to prepare corresponding drug-containing serum （blank serum and simvastatin-containing serum were prepared using the same protocol）. Human L02 hepatocytes were divided into control group， model group， simvastatin-containing serum group， BYHWD-containing serum group， CC-containing serum group， 30YC-containing serum group， 50YC-containing serum group， and 75YC-containing serum group. Except for the control group， other groups were given 0.2 mol/L oleic acid for 24 h to induce a lipid accumulation model， and then intervened with 20% drug-containing serum/blank serum for 24 h. The lipid deposition in cells was observed， and the proportion of lipid droplet area was calculated； the levels of triglycerides （TG） and indicators of oxidative stress [malondialdehyde （MDA）， superoxide dismutase （SOD）] as well as liver function [alanine amino- transferase （ALT）， aspartate amino-transferase （AST）] in cells were detected； protein and mRNA expressions of AMP-activated protein kinase （AMPK）/sterol regulatory element-binding protein-1 （SREBP-1）/glycerol-3-phosphate acyltransferase （GPAT） signaling pathway were also measured. RESULTS Compared with the control group， cells in the model group exhibited severe cellular steatosis， with a significantly increased proportion of lipid droplet area， as well as the elevated levels of TG， ALT， AST， and MDA in cells， along with significantly up-regulated mRNA and protein expression levels of SREBP-1 and GPAT （P＜0.05）. The level of SOD， mRNA expression of AMPK， as well as the protein phosphorylation level of AMPK were decreased significantly （P＜0.05）. Compared with the model group， cellular steatosis was alleviated in all drug-containing serum groups， and the levels of most of the aforementioned quantitative indicators were significantly reversed （P＜0.05）. CONCLUSIONS BYHWD and its active fractions can exert a therapeutic effect on improving non-alcoholic fatty liver disease by regulating the AMPK/SREBP-1/GPAT signaling pathway， inhibiting oxidative stress responses， and reducing lipid deposition.

OBJECTIVE To investigate the effects of Buyang huanwu decoction on red blood cells in hyperlipidemia model mice. METHODS Male C57BL/6 mice were fed a high-fat diet to prepare a hyperlipidemia model. Successfully modeled mice were randomly assigned to the model group， atorvastatin calcium group （0.26 g/kg）， fenofibrate group （1.3 mg/kg）， and high-， medium-， and low- dose groups of Buyang huanwu decoction （18.6， 9.3， 4.6 g/kg）， with 10 mice in each group. Additionally， 10 mice fed with regular chow served as the normal group. Each group of mice received intragastric administration with the corresponding drug or normal saline once daily for 21 consecutive days. After the last administration， the body weight of the mice in each group was measured， and blood glucose， total cholesterol （TC）， triglyceride （TAG）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） levels were measured. Red blood cell morphology changes were observed， and the expression levels of glucose transporter type 1 （GLUT1）， erythrocyte membrane protein band 4.2 （protein 4.2）， caveolin-1， and flotillin-1 in erythrocyte membrane were determined. RESULTS Compared with the model group， the body weight and levels of TC， TAG， HDL-C， LDL-C， and the expression levels of GLUT1， caveolin-1 and flotillin-1 in the Buyang huanwu decoction groups were significantly decreased， while blood glucose levels and the expression levels of protein 4.2 were significantly increased （P＜0.05）. The red blood cell morphology in the low- and medium-dose groups of Buyang huanwu decoction was significantly promoted. CONCLUSIONS Buyang huanwu decoction can reduce blood lipid levels in hyperlipidemia model mice and strengthen the morphology and function of red blood cells in a hyperlipidemic environment， which has the potential to be used for preventing hyperlipidemia complications such as atherosclerosis.

Objective:To explore the effect of pain nursing based on acknowledge, introduce, duration, explanation, thank you (AIDET) communication model on postoperative pain and psychological resilience of patients with tibial fractures.Methods:From January 2019 to April 2021, convenience sampling was used to select 98 patients with tibial fractures from Shanxi Provincial People's Hospital as the study subject. A total of 56 patients who received routine nursing before May 2020 were assigned to the control group, and 42 patients who received pain nursing based on AIDET communication model after May 2020 were assigned to the observation group. All patients received nursing intervention from 12 nurses in the department. The scores of the Self-Rating Anxiety Scale (SAS) , Pittsburgh Sleep Quality Index (PSQI) , Self-Rating Depression Scale (SDS) , and Connor-Davidson Resilience Scale (CD-RISC) , as well as the pain before and after 10 days of intervention between two groups of patients were compared. The ambulation time, hospital stay, and fracture healing time between the two groups of patients were compared.Results:After intervention, the SAS, SDS, and PSQI scores of the observation group were lower than those of the control group ( P<0.05) , while the scores of all dimensions of CD-RISC were higher than those of the control group ( P<0.05) , and the differences were statistically significant. The severity of pain in the observation group was lower than that in the control group, and the difference was statistically significant ( P<0.05) . After follow-up, the ambulation time and fracture healing time in the observation group were shorter than those in the control group with statistical differences ( P<0.05) . Conclusions:AIDET communication model-based pain nursing in patients with tibial fractures can alleviate negative emotions and postoperative pain, and promote postoperative recovery.

Objective:To retrieve and obtain evidence related to postoperative rehabilitation training of patients with lumbar disc herniation and to summarize the best evidence.Methods:The computer was used to search domestic and foreign guideline networks, evidence-based databases, original research databases and orthopedic related websites for relevant evidence on rehabilitation training for patients with lumbar disc herniation after surgery, including evidence summary, guidelines, expert consensus, systematic review and Meta-analysis. The retrieval time limit was from the establishment of the database to April 30, 2021. The literature quality evaluation, evidence extraction, classification and integration were conducted independently by two researchers, and disagreements were discussed or adjudicated by a third party.Results:A total of 14 articles were included, including 3 evidence summaries, 1 guideline, 6 expert consensuses, and 4 systematic reviews. A total of 13 best evidences of rehabilitation training for patients with lumbar disc herniation after surgery were summarized in 8 categories, including rehabilitation assessment, rehabilitation principle, rehabilitation time, rehabilitation intensity, rehabilitation mode, patient education, rehabilitation psychotherapy and follow-up monitoring.Conclusions:This study can provide evidence-based basis for nursing staff to carry out postoperative rehabilitation guidance, but in clinical practice, physical, psychological and cultural background conditions of patients should be comprehensively assessed, and individualized rehabilitation programs should be formulated for patients based on local medical level and conditions.

Objective:To explore the effect of nursing interventions based on individual and family self-management theory (IFSMT) on postoperative rehabilitation of patients undergoing percutaneous transforaminal endoscopic surgery.Methods:A total of 835 patients who underwent percutaneous transforaminal endoscopic surgery in Shanxi Provincial People's Hospital from January 2018 to January 2020 were selected as research objects by the convenient sampling method. According to the random envelope method, patients were divided into the control group ( n=417) and the observation group ( n=418) according to the approximate 1∶1 standard. The control group was given routine nursing intervention, while the observation group was given nursing intervention based on IFSMT on the basis of the control group. The differences in self-management ability, postoperative recovery time, lumbar functional recovery, pain score and postoperative complication rate before and after intervention were compared between the two groups. Results:After intervention, the scores of treatment management, psychological management, life management and knowledge and skill management in the observation group were higher than those before intervention and were higher than those in the control group, and the differences were statistically significant ( P<0.01). The hospitalization days, self-care time and work recovery time of observation group were shorter than those of control group, and the differences were statistically significant ( P<0.01). After intervention, the Oswestry dysfunction index and pain score in the observation group were lower than those before intervention and lower than those in the control group. The treatment score evaluated by the Japanese Orthopedic Association was higher than that before intervention and higher than that of the control group, and the differences were statistically significant ( P<0.01). The incidence of postoperative complications in observation group was lower than that in control group, and the difference was statistically significant ( P<0.05) . Conclusions:IFSMT based nursing intervention for patients undergoing percutaneous foraminal endoscopic surgery is beneficial to postoperative rehabilitation of patients, which is worthy of clinical promotion.

Objective To investigate the dynamic changes and prognosis of thyroid function in the patients with chronic hepatitis C (CHC)after antiviral treatment,and to clarify the influence of baseline factors in the changes of thyroid function.Methods 243 CHC patients with normal baseline thyroid function were enrolled. All patients were treated with IFN-alpha-2b(IFN-α2b)combined with ribavirin for 48 weeks.The thyroid function and serum HCV RNA level were assessed at 12,24,36,48,60 and 72 weeks.According to the changes in thyroid function after treatment,the patients were divided into continued normal,subclinical hypothyroidism,hypothyroidism and hyperthyroidism groups.The regularity of the changes of thyroid function of the patients in various groups were observed.Results Among 243 CHC patients,82(33.7%)patients had thyroid dysfunction.The prevalence of subclinical hypothyroidism,hypothyroidism and hyperthyroidism were 20.9%(51/243),5.3%(13/243)and 7.4%(18/243),respectively. At the end of 72 weeks,there were 32 (39.0%)patients suffering from subclinical hypothyroidism,12 (14.6%) patients with hypothyroidism and 7 (8.5%) patients with hyperthyroidism rehabilitated.6(7.3%)patients suffering from hypothyroidism turned to subclinical hypothyroidism,and 3(3.7%) patients suffering from hyperthyroidism turned to subclinical hypothyroidism.19(23.2%)patients had no significant change,they performed for continued subclinical hypothyroidism (1,1.2%),hypothyroidism (13,15.9%)and hyperthyroidism (5 , 6.1%).In addition, 3 (3.7%)patients with hyperthyroidism turned to hypothyroidism.An increased risk for hypothyroidism was found in female patients compared with males (P<0.05);the average age of the patients with hyperthyroidism was lower than those of the patients with hypothyroidism, subclinical hypothyroidism and continued normal (P<0.05);the baseline levels of GGT in the patients with hyperthyroidism and hypothyroidism were lower than those of the patients with subclinical hypothyroidism and continued normal(P<0.05).The ratio of the patients with HCV 2a to the patients with hypertyroidism was higher than those of the patients with hypothyroidism,subclinical hypothyroidism and continued normal(P<0.05).Conclusion Thyroid function in the CHC patients can be affected by antiviral treatment. Gender, age, liver function, genotype of HCV are influencing factors for the changes of thyroid function.
