ABSTRACT
AIM: To investigate diabetic retinopathy (DR) prevalence in Chinese renal-biopsied type 2 diabetes mellitus (T2DM) patients with kidney dysfunction, and to further evaluate its relationship with diabetic nephropathy (DN) incidence and the risk factors for DR development in this population. METHODS: A total of 84 renal-biopsied T2DM patients were included. Fundus and imaging examinations were employed for DR diagnosis. Demographic information and clinical measures along with renal histopathology were analyzed for comparisons between the DR and non-DR groups. Risk factors on DR development were analyzed with multiple logistic regression. RESULTS: DR prevalence was 50% in total. The incidences of DN, non-diabetic renal disease (NDRD) and mixed-type pathology were 47.6%, 19.0% and 33.3% in the DR group respectively, while 11.9%, 83.3% and 4.8% in the non-DR group. Systolic blood pressure, ratio of urinary albumin to creatine ratio, urinary albumin, 24-hours urinary protein, the incidence and severity of DN histopathology were found statistically increased in the DR group. Multiple logistic regression analysis showed histopathological DN incidence significantly increased the risk of DR development [odds ratio (OR)=21.664, 95% confidential interval (CI) 5.588 to 83.991, P<0.001 for DN, and OR=45.475, 95%CI 6.949 to 297.611, P<0.001 for mixed-type, respectively, in reference to NDRD)], wherein DN severity positively correlated. CONCLUSION: Renal histopathological evidence indicates DN incidence and severity increases the risk of DR development in Chinese T2DM patients inexperienced of regular fundus examinations.
ABSTRACT
Indigenous animal genetic resources play a crucial role in preserving global genetic diversity and supporting the livelihoods of millions of people. In Ethiopia, the majority of the cattle population consists of indigenous breeds. Understanding the genetic architecture of these cattle breeds is essential for effective management and conservation efforts. In this study, we sequenced DNA samples from 70 animals from seven indigenous cattle breeds, generating about two terabytes of pair-end reads with an average coverage of 14X. The sequencing data were pre-processed and mapped to the cattle reference genome (ARS-UCD1.2) with an alignment rate of 99.2%. Finally, the variant calling process produced approximately 35 million high-quality SNPs. These data provide a deeper understanding of the genetic landscape, facilitate the identification of causal mutations, and enable the exploration of evolutionary patterns to assist cattle improvement and sustainable utilization, particularly in the face of unpredictable climate changes.

Platinum-based chemotherapy drugs can lead to the development of anorexia, a detrimental effect on the overall health of cancer patients. However, managing chemotherapy-induced anorexia and subsequent weight loss remains challenging due to limited effective therapeutic strategies. Growth differentiation factor 15 (GDF15) has recently gained significant attention in the context of chemotherapy-induced anorexia. Here, we report that hepatic GDF15 plays a crucial role in regulating body weight in response to chemo drugs cisplatin and doxorubicin. Cisplatin and doxorubicin treatments induce hepatic Gdf15 expression and elevate circulating GDF15 levels, leading to hunger suppression and subsequent weight loss. Mechanistically, selective activation by chemotherapy of hepatic IRE1α-XBP1 pathway of the unfolded protein response (UPR) upregulates Gdf15 expression. Genetic and pharmacological inactivation of IRE1α is sufficient to ameliorate chemotherapy-induced anorexia and body weight loss. These results identify hepatic IRE1α as a molecular driver of GDF15-mediated anorexia and suggest that blocking IRE1α RNase activity offers a therapeutic strategy to alleviate the adverse anorexia effects in chemotherapy.

Osteoarthritis (OA) is a degenerative disease with a high prevalence in the elderly population, but our understanding of its mechanisms remains incomplete. Analysis of serum exosomal small RNA sequencing data from clinical patients and gene expression data from OA patient serum and cartilage obtained from the GEO database revealed a common dysregulated miRNA, miR-199b-5p. In vitro cell experiments demonstrated that miR-199b-5p inhibits chondrocyte vitality and promotes extracellular matrix degradation. Conversely, inhibition of miR-199b-5p under inflammatory conditions exhibited protective effects against damage. Local viral injection of miR-199b-5p into mice induced a decrease in pain threshold and OA-like changes. In an OA model, inhibition of miR-199b-5p alleviated the pathological progression of OA. Furthermore, bioinformatics analysis and experimental validation identified Gcnt2 and Fzd6 as potential target genes of MiR-199b-5p. Thus, these results indicated that MiR-199b-5p/Gcnt2 and Fzd6 axis might be a novel therapeutic target for the treatment of OA.

OBJECTIVES: Postoperative neurocognitive disorder following thoracoscopic surgery with general anaesthesia may be linked to reduced intraoperative cerebral oxygenation and perioperative inflammation, which can potentially be exacerbated by mechanical ventilation. However, nonintubated thoracoscopic surgery, which utilizes regional anaesthesia and maintains spontaneous breathing, provides a unique model for studying the potential benefits of avoiding mechanical ventilation. This approach allows investigation into the impact on perioperative neurocognitive profiles, inflammatory responses and intraoperative cerebral oxygen levels. METHODS: In total, 110 patients undergoing thoracoscopic surgery were randomly equally assigned to the intubated group and the nonintubated group. Regional cerebral oxygenation was monitored during surgery. Serum neuroinflammatory biomarkers, including interleukin-6 and glial fibrillary acidic protein, were measured at baseline (before surgery) and 24 h after surgery. Postoperative complication severity was compared using the Comprehensive Complication Index. The primary outcome was perioperative changes in neurocognitive test score, which was assessed at baseline, 24 h and 6 months after surgery. RESULTS: Patients in the nonintubated group had higher neurocognitive test scores at 24 h (69.9 ± 10.5 vs 65.3 ± 11.8; P = 0.03) and 6 months (70.6 ± 6.7 vs 65.4 ± 8.1; P < 0.01) after surgery and significantly higher regional cerebral oxygenation over time during one-lung ventilation (P = 0.03). Patients in the intubated group revealed a significantly higher postoperative serum interleukin-6 level (group by time interaction, P = 0.04) and a trend towards a significantly higher serum glial fibrillary acidic protein level (group by time interaction, P = 0.11). Furthermore, patients in the nonintubated group had a significantly lower Comprehensive Complication Index (9.0 ± 8.2 vs 6.1 ± 7.1; P < 0.05). CONCLUSIONS: Nonintubated thoracoscopic surgery was associated with improved postoperative neurocognitive recovery, more stable intraoperative cerebral oxygenation, ameliorated perioperative inflammation and attenuated postoperative complication severity.

ABSTRACT
【Objective】 To systematically evaluate the safety and efficacy of intraoperative cell salvage (IOCS) for placenta previa women undergoing cesarean section. 【Methods】 The PubMed, Web of Science, Embase, the Cochrane Library of clinical trials, China National Knowledge Infrastructure (CNKI) and Wan Fang databases were searched from inception to September 2022. The standardized mean differences (SMDs) or relative risk (RR) and 95% confidence intervals (CIs) and prediction intervals (PIs) regarding the comparison between the IOCS and allogeneic blood transfusion (ABT) groups were analyzed using R software Version 4.1.2 and Stata Version 12.0. 【Results】 Five RCTs and ten retrospective cohort studies were included in this meta-analysis. Analysis of cohort studies showed that compared with the ABT group, women with placenta previa who underwent IOCS had generally higher postoperative hemoglobin (Hb) (SMD, 0.626; 95% CI: 0.103 to 1.149; 95% PI: -1.320 to 2.572) and hematocrit (Hct) (SMD, 0.617; 95% CI: 0.130 to 1.104; 95% PI: -1.084 to 2.317) levels. In RCTs, we observed that placenta previa women undergoing IOCS were almost 72.7% less likely to suffer from adverse events AEs than the ABT group (RR, 0.273; 95% CI, 0.082 to 0.904). The difference in postoperative prothrombin time (PT), activated prothrombin time (APTT), fibrinogen (Fib) concentration, blood urea nitrogen (BUN) and creatinine (Cr) between the IOCS and ABT group did not reach statistical significance. 【Conclusion】 Women with placenta previa who undergo IOCS have higher postoperative Hb and Hct concentrations compared to those treated with ABT. IOCS has no major effects on postoperative coagulation parameters and renal function parameters. IOCS is associated with a significantly lower risk of transfusion-related AEs among women undergoing cesarean section.

ABSTRACT
Objective: To investigate the prevalence of work-related musculoskeletal disorders(WMSDs) among intensive care unit (ICU) nurses, assess its relationship with ergonomic load and overall exposure levels. Methods: A total of 272 ICU nurses from two tertiary hospitals in a city were selected as the research subjects using convenient sampling method. The Chinese Musculoskeletal Disorder Questionnaire was used to investigate the prevalence of WMSDs among the ICU nurses. The Quick Exposure Check (QEC) was used to assess the ergonomic load on the back, shoulder/arm, hand/wrist, and neck during different clinical nursing operations. Results: The annual prevalence of WMSDs was 75.7% among ICU nurses. The annual prevalence of WMSDs in different body parts, from high to low, was as follows: lower back, neck, shoulder/arm, back, knee, hip/leg, hand/wrist, ankle/foot, and elbow (54.8% vs 43.4% vs 40.8% vs 36.0% vs 21.3% vs 19.9% vs 18.8% vs 18.4% vs 8.1%, P<0.01). ICU nurses had the highest QEC scores on the back (dynamic), shoulder/arm, hand/wrist, and neck with assisting patient turning (all P<0.05) among the six clinical nursing items. During the operation of patient turning, patient lifting, patient bathing, and bed sheet changing for bedridden patients, the back (dynamic) and shoulder/arm were at a high load level, while the hand/wrist and neck were at a mild load level. When nurses were providing tracheostomy care and oral care for intubated patients, their back (static), shoulder/arm, hand/wrist, and neck were at a mild load level. The overall exposure rate for assisting patient turning, patient lifting, oral care for intubated patients, bed sheet changing for bedridden patients, patient bathing, and tracheostomy care were 77.8%, 66.5%, 63.6%, 60.2%, 58.5%, and 57.4%, respectively. The risk for assisting patient turning was classified as level four, while the risk for other clinical nursing items was level three. Conclusion: The prevalence of WMSDs in ICU nurses is high. Both ergonomic load level and total exposure rate of back, shoulder/arm, hand/wrist and neck were high during clinical nursing operations.
ABSTRACT
OBJECTIVES@#To investigate the therapeutic effect of recombinant human growth hormone (rhGH) on children with growth hormone deficiency (GHD) and different pituitary developmental conditions.@*METHODS@#A prospective study was performed on 90 children with GHD who were admitted to Xuchang Maternity and Child Health Hospital from June 2020 to December 2021. According to pituitary height on the median sagittal plane, they were divided into three groups: pituitary dysplasia group (n=45), normal pituitary group (n=31), and enlarged pituitary growth group (n=14). The changes in body height, growth velocity, height standard deviation score and serum levels of insulin-like growth factor binding protein-3 (IGFBP-3) and insulin-like growth factor-1 (IGF-1) were examined after treatment in the above three groups, and the differences of the above indices before and after treatment were compared among the three groups.@*RESULTS@#After treatment, all three groups had significant increases in body height, growth velocity, height standard deviation score, and the serum levels of IGFBP-3 and IGF-1 (P<0.05). Compared with the normal pituitary group, the pituitary dysplasia group and the enlarged pituitary growth group had significantly higher values in terms of the differences in body height, growth velocity, height standard deviation score, IGF-1, and IGFBP-3 before and after treatment (P<0.05). There was no significant difference in the incidence rate of adverse reactions among the three groups (P>0.05).@*CONCLUSIONS@#In GHD children with different pituitary developmental conditions, rhGH can promote bone growth and increase body height, especially in children with pituitary dysplasia and pituitary hyperplasia, with good safety.

Objective: To analyze the clinical characteristics and prognostic value of liver function in a large samples of patients with anti-glycoprotein 210 (gp210 antibody) positive primary biliary cholangitis (PBC). Methods: A retrospective study was performed on 931 PBC cases in Beijing You'an Hospital affiliated to Capital Medical University from 2010 to 2019. According to the detection of gp210 antibody, 318 cases were divided into gp210 antibody positive group (positive group) and 613 cases were divided into gp210 antibody negative group (negative group). The differences in demographic, medical history, clinical indicators, B-ultrasound and pathological indicators as well as the histopathological basis were compared between the two groups. SPSS 16.0 software was used for statistical analysis. Measurement data were analyzed by t-test or rank sum test, and enumeration data by χ2 test. Multivariate analysis was used for logistic test, and and survival analysis was used for prognosis. Results: The positive and the negative groups were compared. The ratio of male to female was significantly higher in positive than negative group (1:5.35 vs. 1:9.73, P<0.05), and the difference was statistically significant. The proportion of hormone use in history of past diagnosed and treated was higher in positive than negative group (12.9% vs. 3.47%, P<0.05), and the difference was statistically significant. The detection of biochemical indexes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT) were higher in positive than the negative group (51.1 U/L vs. 41.1 U/L, 62.6 U/L vs. 49.6 U/L, 24.1 μmol/L vs. 17.9 μmol/L, 228.3 U/L vs. 169.6 U/L, 203.9 U/L vs. 147.6 U/L), (P<0.05), and the differences were statistically significant. Antinuclear antibody (ANA)-positive rate, high titer ratio and immunoglobulin G (IgG) levels were higher in positive than negative group (95.2% vs. 81.6%, 69.7% vs. 48.8%, 17.2 g/L vs. 16.2 g/L), (P<0.05), and the differences were statistically significant. The incidence of liver failure was higher in positive than negative group (P<0.05). CK7 and inflammation score were higher in positive group than negative group in liver histopathological observations (0.83±0.53 vs. 0.28±0.47; 1.06±0.39 vs. 0.54±0.65), (P<0.05), and the differences were statistically significant. Conclusion: The illness condition of patients with gp210 antibody positive PBC is more severe than patients with gp210 antibody negative PBC, and the incidence of liver failure is significantly increased. Cholangiocytes may be the histopathological basis of the clinical characteristics of gp210 antibody positive PBC patients.

ABSTRACT
Objective:Acute kidney injury (AKI) is one of the common complications in critically ill septic patients, which is associated with increased risks of death, cardiovascular events, and chronic renal dysfunction. The duration of AKI and the renal function recovery status after AKI onset can affect the patient prognosis. Nevertheless, it remains controversial whether early recovery status after AKI is closely related to the prognosis in patients with sepsis-associated AKI (SA-AKI). In addition, early prediction of renal function recovery after AKI is beneficial to individualized treatment decision-making and prevention of severe complications, thus improving the prognosis. At present, there is limited clinical information on how to identify SA-AKI patients at high risk of unrecovered renal function at an early stage. The study aims to investigate the association between early recovery status after SA-AKI, identify risk factors for unrecovered renal function, and to improve patients ' quality of life.Methods:We retrospectively analyzed clinical data of septic patients who were admitted to the intensive care unit (ICU) and developed AKI within the first 48 hours after ICU admission in the Second Xiangya Hospital and the Third Xiangya Hospital of Central South University from January 2015 to March 2017. Sepsis was defined based on the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). AKI was diagnosed and staged according to the 2012 Kidney Disease:Improving Global Outcomes (KDIGO) guideline. SA-AKI patients were assigned into 3 groups including a complete recovery group, a partial recovery group, and an unrecovered group based on recovery status at Day 7 after the diagnosis of AKI. Patients ' baseline characteristics were collected, including demographics, comorbidities, clinical and laboratory examination information at ICU admission, and treatment within the first 24 hours. The primary outcome of the study was the composite of death and chronic dialysis at 90 days, and secondary outcomes included length of stay in the ICU, length of stay in the hospital, and persistent renal dysfunction. Multivariate regression analysis was performed to evaluate the prognostic value of early recovery status after AKI and to determine the risk factors for unrecovered renal function after AKI. Sensitivity analysis was conducted in patients who still stayed in hospital on Day 7 after AKI diagnosis, patients without premorbid chronic kidney disease, and patients with AKI Stage 2 to 3.Results:A total of 553 SA-AKI patients were enrolled, of whom 251 (45.4%), 73 (13.2%), and 229 (41.4%) were categorized as the complete recovery group, the partial recovery group, and the unrecovered group, respectively. Compared with the complete or partial recovery group, the unrecovered group had a higher incidence of 90-day mortality (unrecovered vs partial recovery or complete recovery: 64.2% vs 26.0% or 22.7%; P<0.001) and 90-day composite outcome (unrecovered vs partial recovery or complete recovery:65.1%vs 27.4%or 22.7%;P<0.001). The unrecovered group also had a shorter length of stay in the hospital and a larger proportion of progression into persistent renal dysfunction than the other 2 groups. After adjustment for potential confounders, patients in the unrecovered group were at an increased risk of 90-day mortality (HR=3.50, 95% CI 2.47 to 4.96, P<0.001) and 90-day composite outcome (OR=5.55, 95%CI 3.43 to 8.98, P<0.001) when compared with patients in the complete recovery group, but patients in the partial recovery group had no significant difference (P>0.05). Male sex, congestive heart failure, pneumonia, respiratory rate>20 beats per minute, anemia, hyperbilirubinemia, need for mechanical ventilation, and AKI Stage 3 were identified as independent risk factors for unrecovered renal function after AKI. The sensitivity analysis further supported that unrecovered renal function after AKI remained an independent predictor for 90-day mortality and composite outcome in the subgroups. Conclusion:The early recovery status after AKI is closely associated with poor prognosis in critically ill patients with SA-AKI. Unrecovered renal function within the first 7 days after AKI diagnosis is an independent predictor for 90-day mortality and composite outcome. Male sex, congestive heart failure, pneumonia, tachypnea, anemia, hyperbilirubinemia, respiratory failure, and severe AKI are risk factors for unrecovered renal function after AKI. Therefore, timely assessment for the renal function in the early phase after AKI diagnosis is essential for SA-AKI patients. Furthermore, patients with unrecovered renal function after AKI need additional management in the hospital, including rigorous monitoring, avoidance of nephrotoxin, and continuous assessment for the renal function, and after discharge, including more frequent follow-up, regular outpatient consultation, and prevention of long-term adverse events.

ABSTRACT
Objective:To explore the prognostic factors of epithelial ovarian carcinoma (EOC), construct a nomogram model, and evaluate the prognosis of EOC patients.Methods:A retrospective analysis was performed on clinicopathological data of 208 cases of EOC patients who received initial treatment in the First Affiliated Hospital of Army Medical University from August 11, 2016 to July 11, 2018, including age, preoperative ascites, preoperative neoadjuvant chemotherapy, surgical method, pathological type, pathological differentiation degree, surgical pathology stage, preoperative and post-chemotherapy serum cancer antigen 125 (CA 125) level, human epididymal protein 4 (HE4) level, platelet count and platelet/lymphocyte number ratio (PLR). The univariate and multivariate Cox risk ratio models were used to analyze the related factors affecting progression free survival (PFS) in EOC patients, and the prediction nomogram of PFS in EOC patients was established to evaluate its efficacy in predicting PFS. Results:Univariate analysis showed that preoperative neoadjuvant chemotherapy, pathological type, pathological differentiation degree, surgical pathology stage, serum CA 125 and HE4 level before operation and after chemotherapy, platelet count and PLR before operation and after chemotherapy were significantly correlated with PFS in EOC patients (all P<0.05). Multivariate analysis showed that surgical pathology stage, preoperative PLR, serum CA 125 and HE4 level after chemotherapy were independent prognostic factors affecting PFS of EOC patients (all P<0.01). The index coefficient of the prediction model for the prognosis of EOC patients established by this method was 0.749 (95% CI: 0.699-0.798), which had good prediction ability, and could help clinicians to more accurately evaluate the prognosis of EOC patients. Conclusion:The nomogram model constructed based on surgical pathology stage, preoperative PLR, serum CA 125 and HE4 level after chemotherapy could effectively predict the PFS of EOC patients after initial treatment, could help clinicians to screen high-risk patients, provide individualized treatment, and improve the prognosis of EOC patients.

Routine questionnaires were used to collect general demographic data, overweight and obesity and risk factors information of the subjects. At the same time, the incidence of obesity was calculated based on the BMI level. Results The proportion of abnormal lipids in high altitude residents(35.68%,38.96%,41.78%,33.80%,35.21%)was higher than that in low altitude residents(23.49%,21.85%,25.68%,25.68%,19.67%).The proportion of abnormal lipids in male group(21.39%,18.90%,16.91%,15.92%,22.38%)was higher than that in female group(13.33%,11.28%,8.20%,9.23%,14.35%).The proportion of abnormal lipids in 60-80 years old group(32.51%,21.47%,23.31%,20.24%,25.15%)was higher than that in 18-44 years old group(18.67%,2.48%,12.00%,2.48%,14.67%)and 45-59 years old group(16.45%,12.02%,13.92)%,10.75%,14.55%).The rate of dyslidemia in obese people(27.43%,24.77%,25.66%,8.84%,28.31%)was higher than that in underweight people(20.51%,6.87%,6.87%,15.38%,16.67%),normal weight people(10.14%,7.24%,4.34%,4.34%,5.79%)and the overweight group(16.91%,14.70%,11.76%,12.50%,13.23%)was higher.The rate of dyslidemia in junior college and above group(4.76%,5.95%,5.35%,4.76%,4.16%)was higher than that in primary school and middle school(12.94%,10.58%,8.23%,7.05%,5.88%).High school/technical secondary school(18.18%,18.88%,13.28%,14.68%,16.78%)were lower(P<0.05).In terms of average intake of meat,the proportion of overweight/underintake in obese group(55.15%,33.82%)was higher than that in non-obese group(16.54%,26.15%),and the proportion of normal intake in obese group(11.03%)was lower than that in non-obese group(57.31%).The proportion of excessive/low intake in normal group(18.05%,26.35%)was lower than that in dyslipidemia group(53.78%,26.05%),and the proportion of normal intake in normal group(55.60%)was higher than that in dyslipidemia group(20.17%)(P<0.05).With abnormal blood lipid as the dependent variable and excessive/low meat intake as the independent variable,the regression analysis showed that both excessive/low meat intake were risk factors for abnormal blood lipid(OR=1.134,1.146,P<0.05).Taking obesity as the dependent variable and excessive/low meat intake as the independent variable,the regression analysis showed that both excessive/low meat intake were risk factors for obesity(OR=1.145,1.327,P<0.05).Conclusion The dietary characteristics of people aged 18 and over in the plateau area are unstable. The incidence of dyslipidemia is 30.05%, and the incidence of obesity is 34.34%. Excessive or too little meat intake is associated with dyslipidemia and obesity in this population.
ABSTRACT
ObjectiveTo investigate whether Xiayuxue decoction exerts an anti-liver fibrosis effect by inhibiting glial cell line-derived neurotrophic factor (GDNF). MethodsA total of 24 C57BL/6 mice were randomly divided into control group, model group, and Xiayuxue decoction group. The mice in the model group and the Xiayuxue decoction group were given intraperitoneal injection of 10% CCl4, and those in the Xiayuxue decoction group were given 0.4678 g/kg Xiayuxue decoction by gavage since week 4. The liver function parameters alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured, and liver histopathology was observed. Immunohistochemistry was used to measure the protein expression of alpha-smooth muscle actin (α-SMA) and GDNF. GFP-Col-HSC and human primary hepatic stellate cells (HSCs) were treated with GDNF (10 ng/ml), and HSC activation was measured. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the control group, the model group had significant increases in the levels of ALT and AST, and compared with the model group, the Xiayuxue decoction group had significant reductions in the levels of ALT and AST (all P<0.01). Liver histopathology showed that the model group had marked inflammatory cell infiltration and formation of fibrous septa by proliferated collagen fibers, and the Xiayuxue decoction group had loose fibrous septa and alleviated inflammatory cell infiltration. Immunohistochemistry showed that compared with the control group, the model group had significant increases in the expression of α-SMA and GDNF (both P<0.01), which were observed in fibrous septa, and compared with the model group, the Xiayuxue decoction group had significant reductions in the expression of α-SMA and GDNF (both P<0.05). Western blotting showed that the control group had relatively low expression of GDNF in liver tissue, the formation of liver fibrosis at week 6 of CCl4 modeling, and an around 10-fold increase in the expression of GDNF, and the Xiayuxue decoction group had significantly inhibited protein expression of GDNF (P<0.01); there were significant increases in the expression of α-SMA and collagen type I α1 (Col1) in mice with liver fibrosis, with significant reductions in α-SMA and Col1 after treatment with Xiayuxue decoction (all P<0.01). The in vitro experiment showed that GDNF induced the significant increases in the protein expression of α-SMA and Col1 in HSCs, which was significantly inhibited by Xiayuxue decoction (all P<0.01). ConclusionThe expression of GDNF is significantly upregulated in the formation of liver fibrosis. GDNF can induce HSC activation, and Xiayuxue decoction can exert an anti-liver fibrosis effect by inhibiting GDNF.
ABSTRACT
Objective:To observe the effect of enriched rehabilitation training on cognitive function, plasma mir-146a-5p microRNA precursor levels and inflammatory factors in persons with post-stroke cognitive impairment (PSCI).Methods:Fifty-eight persons with PSCI were randomly divided into an observation group and a control group, each of 29. The observation group was given enriched rehabilitation training, while the control group was provided with conventional cognitive rehabilitation training. The Montreal Cognitive Assessment Scale (MoCA), the Digit Span Test (DST), parts A and B of the Trail Making Test (TMT A-B) and the Modified Barthel Index (MBI) were used to assess the subjects′ cognitive functioning and their ability in the activities of daily living (ADL). Plasma levels of mir-146a-5p, IL-6 and TNF-α were detected before and after the treatment.Results:After treatment, the average MOCA, DST and MBI scores, as well as the average TMT A-B times had improved significantly for both groups. However, the observation group′s averages were significantly better than those of the control group on all three tests. After the treatment, the average plasma expression of miR-146a-5p had increased significantly in both groups, but the increase in the observation group was significantly greater. Plasma IL-6 and TNF-α levels were significantly lower than before the treatment, with the average TNF-α level in the observation group significantly lower than that of the control group.Conclusions:Enriched rehabilitation training can improve the cognition of stroke survivors more effectively than conventional cognitive rehabilitation training. That may be related to the up-regulation of plasma miR-146a-5p and reducing inflammation.
ABSTRACT
Objective:To observe the clinical efficacy of modified Buyang Huanwutang combined with electroacupuncture (EA) in the treatment of traumatic spinal cord injury (TSCI) due to Qi deficiency and blood stasis. Method:Eighty-seven TSCI patients who met the inclusion requirements were randomly divided into an observation group (<italic>n</italic>=44) and a control group (<italic>n</italic>=43). On the basis of comprehensive western medical treatments, patients in the control group were further provided with Wuwei Tongshuan oral liquid,10 mL per time,three times per day, while those in the observation group received modified Buyang Huanwutang,one bag per day,for 12 consecutive weeks. Besides, EA was performed in both groups in the same way, once per day, six times per week, for six weeks in total. The American Spinal Injury Association (ASIA) motor score, modified Barthel index (MBI),visual analog scale (VAS) pain score,Berg balance scale (BBS) score,modified Ashworth scale (MAS) score, spinal cord independence measure-Ⅲ(SCIM-Ⅲ) score, lower limb range of motion (ROM), and Qi deficiency and blood stasis syndrome score before and after treatment were evaluated, followed by the recording of the occurrence of complications during treatment. The brain-derived nerve growth factor (BDNF), nerve growth factor (NGF), vascular endothelial growth factor (VEGF), neurotrophic factor-3 (NT-3), malondialdehyde (MDA) and superoxide dismutase (SOD) levels before and after treatment were determined. Result:The motor, light touch, needling sensation, MBI, and BBS scores of the observation group were higher than those of the control group (<italic>P</italic><0.01), while the AS and MAS scores were lower(<italic>P</italic><0.01). The angles of adductor and straight leg raising in the observation group were greater than those of the control group (<italic>P</italic><0.01),but the Qi deficiency and blood stasis syndrome score was lower(<italic>P</italic><0.01). Both the scores of self-care, respiration, and sphincter management in SCIM-Ⅲ and the total score in the observation group were elevated as compared with those of the control group (<italic>P</italic><0.01). The cumulative incidence of complications in the observation group was 34.09%,significantly lower than 55.81% in the control group (<italic>χ</italic><sup>2</sup>=4.149,<italic>P</italic><0.05). Compared with the control group, the observation group exhibited remarkably increased BDNF, NGF, VEGF, NT-3, and SOD (<italic>P</italic><0.01) and decreased MDA (<italic>P</italic><0.01). Conclusion:Modified Buyang Huanwutang combined with EA is effective in alleviating spinal cord injury, promoting neural functional recovery, improving independence in activities of daily living, reducing the incidence of complications of patients with TSCI, which may be related to the amelioration of ischemia and hypoxia, inhibition of lipid peroxidation, and acceleration of nerve cell repair and regeneration.
