ABSTRACT
Osteogenesis imperfecta（OI）is a hereditary connective tissue disease，and roughly 85% of the patients are caused by heterozygous mutations in COL1A1 and COL1A2，the coding genes of type Ⅰcollagen. Primary symptomatic manifestations of OI are low bone mass，frequent fractures and skeletal deformity，and other symptoms include blue sclera，dentinogenesis imperfecta，hyperlaxity of joint and ligaments，short stature and hearing impairment. Some patients may have muscle weakness，obesity and other symptoms，and the systemic low-grade inflammation and changes in bone microenvironment caused by obesity may have more negative effects on OI bones. The occurrence of obesity in OI patients may be related to energy metabolism abnormalities caused by multiple factors such as reduced activity，abnormal muscle fat metabolism，and diverse genotypes. Currently，there is a lack of large sample data on the incidence of obesity，and exploring the mechanism of skeletal-muscle interaction and energy metabolism regulation is of great significance for OI related obesity prevention and treatment.
ABSTRACT
Objective To study the effect of drinking carbohydrate drinks before cesarean section on mothers and neonates,and to explore the application value of drinking carbohydrate drinks before cesarean section.Methods The clinical data of 206 singleton women who underwent selective cesarean section in Obstetrics and Gynecology Hospital,Fudan University from Jun 2020 to Jun 2021 were retrospectively studied.Patients were divided into enhanced recovery after delivery(ERAD)group and control group according to whether drinking carbohydrate drinks before cesarean section.A retrospective cohort study was conducted to analyze the effect of preoperative carb drinks on preoperative fluid supplementation,postoperative rehabilitation and neonatal prognosis.Results Among patients who fasted for less than 12 hours,the ERAD group had a lower fluid supplementation rate and a smaller average fluid supplementation volume compared to the control group(P＜0.05).The ERAD group had a lower rate of prokinetic agent using after surgery(P＜0.05).Among women without a history of abdominal surgery,the ERAD group had less blood loss 24 hours after surgery(P＜0.05).There were no significant differences in postoperative fever rate,incidence of nausea and vomiting,time of first flatus,neonatal apgar score,exit observation room neonatal blood,and neonatal neonatal intensive care unit(NICU)admission rate between the two groups.Among newborns with high-risk factors for hypoglycemia,the ERAD group had lower enter observation room neonatal blood compared to the control group,and a higher incidence of hypoglycemia(P＜0.05).Conclusion Oral intake of carbohydrate drinks before cesarean section may be beneficial in reducing fluid supplementation before elective cesarean section,promoting postoperative gastrointestinal function recovery,and reducing postoperative bleeding.However,it may be related to the occurrence of neonatal hypoglycemia.
ABSTRACT
Arsenic, a naturally occurring metal-like chemical element, is one of the 10 chemicals of major public concerns listed by the World Health Organization as harmful to the environment and human health. It can enter the human body through breathing, intaking food, drinking water, skin exposure, and other ways, and long-term exposure to arsenic can cause cancer of multiple organs and impaired function of multiple systems. Epigenetic mechanisms play an important role in arsenic-induced health effects, and research suggested that the carcinogenicity of arsenic may be associated with epigenetic changes. Previous studies focused on the effects of arsenic on DNA methylation modification. In recent years, research showed that 5-hydroxymethylcytosine (5-hmC), an intermediate of active demethylation of DNA, can act as a sensitive epigenetic mark and play a crucial role as a "bridge" between arsenic exposure and health effects. Based on the latest research progress on the role of DNA hydroxymethylation in the health effects associated with arsenic exposure, this article briefly described the relationship between the health effects of arsenic exposure and DNA hydroxymethylation, summarized the possible mechanisms of DNA hydroxymethylation in the health effects associated with arsenic exposure, and provided a scientific basis for preventing and treating the health effects associated with arsenic exposure.
ABSTRACT
ObjectiveTo explore the correlation between serum albumin levels and coronary artery calcification （CAC） in patients with early-stage chronic kidney disease （CKD）， as well as the value of serum albumin levels in predicting the incidence and severity of CAC. MethodsThe study included 391 early-stage CKD patients who underwent coronary computed tomography angiography （CTA） at Sun Yat-sen Memorial Hospital of Sun Yat-sen University between January 2019 and December 2022. Demographic and biochemistry data， as well as the coronary CTA results， were collected. Based on the coronary artery calcification score （CACS）， all patients were divided into non-CAC group （CACS=0， n=184） and CAC group （CACS>0， n=207）. All patients were further divided into 3 groups based on the serum albumin levels： group A （serum albumin levels<35 g/L， n=30）， group B （35 g/L≤ serum albumin levels< 40 g/L， n=198） and group C （serum albumin levels≥ 40 g/L， n=163）. Univariate and multivariate binary logistic regression analyses were conducted to investigate the association between serum albumin levels and CAC in early-stage CKD patients. Differences in CAC among groups were analyzed by using post-hoc multiple comparisons and ordinal logistic regression model analysis. ResultsPatients with CAC had significantly lower serum albumin levels than those without CAC （P<0.05）. There was a negative correlation between serum albumin levels and CACS in early-stage CKD patients （P<0.01）， as serum albumin decreased in levels， CAC increased in severity. ConclusionsOur study shows that early-stage CKD patients with lower serum albumin levels have a higher incidence of CAC. Low serum albumin level is an independent risk factor for CAC progression.
ABSTRACT
Alzheimer's disease is a common central neurodegenerative disease， mainly manifested by cognitive impairment and non-cognitive neuropsychiatric symptoms that severely affect patients' daily life and behavioral functioning. The pathogenesis of Alzheimer's disease is still unclear， and the western medicine currently used to treat Alzheimer's disease is only symptomatic， with a single pathway， limited efficacy， and many side effects. In recent years， with the deepening of research on Alzheimer's disease， the study and application of traditional Chinese medicine （TCM） in the treatment of Alzheimer's disease have gradually increased. Several studies have shown that TCM and its effective components can exert anti-Alzheimer's disease effects by regulating molecular mechanisms such as pathological protein production and aggregation， oxidative stress， neuroinflammation， ferroptosis， mitochondrial dysfunction， neurogenesis and neurotransmission， and brain-gut axis. This paper summarized the research progress of TCM in the treatment of Alzheimer's disease in recent years， so as to provide a reference for further study of the specific mechanism of TCM in the prevention and treatment of Alzheimer's disease and the discovery of effective components of TCM.

Objective To investigate the efficacy of percutaneous endoscopic transforaminal approach in the treatment of adolescent lumbar disc herniation(ALDH)complicated with scoliosis.Methods A retrospective study was conducted on clinical data of 28 cases of ALDH complicated with scoliosis from January 2018 to June 2021.Percutaneous endoscopic discectomy through the intervertebral foramen approach was performed.The patients were placed in a prone position.The percutaneous puncture was carried out to insert into the working channel,and the protruding nucleus pulposus was visually removed under the intervertebral foramen to relieve nerve root compression and complete decompression.Results The operation time was 45-75 min,with an average of(60.6±9.3)min.No surgery-related complications such as incision infection or nerve injury were found.All the 28 patients were followed up for 14-30 months,with an average of(20.1±5.1)months.The waist Visual Analogue Scale(VAS),leg VAS,Oswestry Dysfunction Index(ODI),Cobb angle,center sacral vertical line-C7 plumb line(CSVL-C7 PL),and sagittal vertical axis(SVA)were significantly lower at 1 month after operation and at the last follow-up than those before operation,with statistically significant differences(all P =0.000).The waist VAS,leg VAS,ODI,Cobb angle,CSVL-C7 PL,and SVA at the last follow-up were significantly lower than those at 1 month after operation,with statistically significant difference(all P<0.05).During the follow-ups,symptoms recurred in 2 patients,and fenestration of the nucleus pulposus was performed,which relieved the symptoms.The modified MacNab standard efficacy evaluation at the last follow-up showed excellent in 22 cases,good in 4 cases,and fair in 2 cases,with an excellent and good rate of 92.9%(26/28).Conclusion Percutaneous endoscopic transforaminal approach in the treatment of ALDH complicated with scoliosis can relieve clinical symptoms and improve scoliosis,the clinical effect being satisfactory.
ABSTRACT
Objective To explore the value of plaque-to-aorta CT value ratio(standardized CT value)in differentiating coronary lipid and fibrous plaques,and to preliminarily analyze the stability of the cutoff.Methods Patients who underwent coronary computed tomography angiography(CCTA)and intravascular ultrasound(IVUS)within 1 week were included.The plaque CT value was obtained by measuring the all,four and two short-axis planes,respectively.The CT value of the ascending aorta was measured and standardized(plaque-to-aorta CT value ratio).The receiver operating characteristic(ROC)curves of the standardized and the traditional CT values were drawn.Results A total of 60 patients with 74 plaques were included,35 lipid and 39 fibrous plaques were diagnosed by IVUS.The aorta CT value was significantly correlated with the plaque(r=0.420,P<0.01);the cutoffs for the CT value of all,four and two plaque slices were 55 HU,48 HU and 52 HU,respectively,and all there of the cutoffs of standardized CT value were 0.149;the sensitivity,specificity,positive predictive value(PPV)and negative predictive value(NPV)of four-slice traditional and standardized CT values to differentiate lipid and fibrous plaques were 69%,87%,83%,76%and 91%,82%,82%,91%,respectively.Conclusion Compared with traditional CT value,the standardized CT value can greatly improve the sensitivity and NPV in differentiating coronary lipid and fibrous plaques,while maintaining modest to high specificity and PPV.Furthermore,the cutoff is stable.
ABSTRACT
Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.
ABSTRACT
Objective:To explore a set of procedures for the effictive granulation of cartilage,and to construct injectable cartilage graft with platelet-rich gel(PRG),and to evaluate its effects in nude mice models.Methods:The costal cartilage of adult male rab-bits was cut into pieces and placed in a mortar for 30-60 s freezing in liquid nitrogen and grinding for a short time to obtain granular cartilage.Blood was collected from the middle ear artery and PRG was prepared by double centrifugation.Granular cartilage and the mixture of granular cartilage and PRG were injected subcutaneously in nude mice of control group(n=5)and experimental group(n=5)respectively.8 weeks after injection,the gross morphology observation and histological examination were pertormed.The nasal dor-sum augmentation model of nude mice was established in the experimental group.Results:The cartilage particles were in the size of 10-500 pm in diameter after frozen grinding,and injection could be realized.In vitro culture showed that the cell survival rate of granular cartilage reached to 80％.In vivo test showed that the sample morphology of the control group was insignificant,and the sur-face was grainy.That of the experimental group was well maintained,and the surface was smooth with obvious capillaries.The sam-ples of experimental group achieved significant augmentation in the nude mouse model of nasal dorsum augmentation.Conclusion:Freeze-milling technology can achieve efficient granulation of cartilage,and the graft constructed with PRG gel is suitable for maxillo-facial cartilage transplantation repair.
ABSTRACT
Objective:To establish the animal model of cervicofacial venous malformations(VMs)by surgical reconstruction of exter-nal jugular vein in sheep.Methods:The external jugular veins of 5 sheep were dissected,and the position,course,branch and exter-nal diameter were observed and measured.The models of VMs with draining and returning veins were constructed by suturing or constric-ting the proximal part of main trunk and ligating or constricting the distal part of the jugular or branch veins.The animal model was eval-uated by Doppler ultrasound,gross observation and histological observation at the 4th week after surgery.Results:The external jugular veins of sheep is in the lateral side of bilateral neck,and the main trunk is formed by the maxillary vein and lingual facial vein.The ex-ternal diameter ranges from 6 to 12 mm,with an average external diameter of 9.3 mm.Immediately after the external jugular vein was sutured and narrowed at the proximal part of the main vein,the distal part of the vein branch was ligated or narrowed,the blood flow speed slowed down and the veins in the model area bulged.4 weeks after surgery,gross observation showed that most veins narrowed and thrombosis was formed in part of the venous lumen.The central region of some specimens was dilated,and the peripheral collateral veins were dilated in some models.Doppler ultrasonography showed that the lumens of most veins were dilated and the returning veins and the inflow veins were narrowed.Colored blood flow was seen in the lumen.Histological observation showed that the structure of vein endothelium and wall was close to the normal vein,and the vein vessel wall of some specimens was thickened.Conclusion:The VMs model estab-lished by external jugular vein of sheep basically meets the re-quirements and is expected to be used in the therapeutic meth-odology research of cervicofacial VMs.
ABSTRACT
BACKGROUND:Low to moderate intensity aerobic exercise can help protect knee cartilage.Long-chain non-coding RNAs are crucial for gene regulation.Among them,HOTAIR can activate numerous transcriptional co-repressors to repress the activation of certain genes. OBJECTIVE:To detect the expression levels of HOX transcript antisense RNA(HOTAIR)and other related factors in chondrocytes of high fat-fed mice and after low to moderate intensity exercise intervention,and to investigate their role in cartilage injury and sports rehabilitation. METHODS:Thirty C57BL/6 male mice were randomly divided into control group(normal feeding),high fat feeding group and high fat feeding plus treadmill exercise group,with 10 mice in each group.The mice in the high fat feeding plus treadmill exercise group were subjected to an 8-week low to middle intensity treadmill exercise,and the mice in the other two groups were caged.During this period,body mass was weighed every week on Sunday.After the 8-week exercise,both lower extremities of mice were taken,and the knee joint was scanned using Micro CT to make a 3D femoral condyle image to obtain relevant parameters.Hematoxylin-eosin and safranin O-fast green staining of the knee joint were performed for Mankin and Osteoarthritis Research Society International(OARSI)scoring.RT-PCR was performed to detect the mRNA levels of cartilage metabolic indicators and lipid metabolism indicators,including type II collagen,matrix metalloproteinase 13,interleukin 1,low-density lipoprotein receptor-related protein 5,HOTAIR and its downstream factor lysine specific demethylase 1. RESULTS AND CONCLUSION:The body mass of high fat-fed mice were higher than that of the control group(P<0.01),and the body mass of the high fat feeding plus treadmill exercise group was lower than that of the high fat feeding group(P<0.05).The connectivity density of high fat-fed mice was higher than that of the control group(P<0.01).Mankin and OARSI scores of the high fat feeding were higher than those of the control group(P<0.01)and high fat feeding plus treadmill exercise group(P<0.05).The mRNA level of type II collagen was higher in the control group than the high fat feeding plus treadmill exercise group(P<0.05)and high fat feeding group(P<0.01)as well as higher in the high fat feeding plus treadmill exercise group than the high fat feeding group(P<0.01).The mRNA levels of matrix metalloproteinase 13,interleukin 1,low-density lipoprotein receptor-related protein 5,HOTAIR and lysine specific demethylase 1 were higher in the high fat feed group than the control group and high fat feeding plus treadmill exercise group(P<0.01).To conclude,high fat feeding can increase the bone substance of the femoral condyle,lead to knee cartilage wear,and cause chondrocyte metabolism disorder.HOTAIR is highly expressed in this process.An 8-week low to middle intensity treadmill exercise can reduce body mass,alleviate knee cartilage wear,improve chondrocyte function and down-regulate HOTAIR expression in mice.
ABSTRACT
Objective:To investigate the medical narrative competence of pediatric staff, and analyze its influencing factors and correlation with psychological resilience, and to discuss strategies to improve narrative competence.Methods:From January 11 to February 25, 2022, by convenience sampling, we sampled pediatric personnel and those on refresher training at Children's Hospital, Zhejiang University School of Medicine for a questionnaire survey involving general information, the narrative competence scale, and the 14-item resilience scale. With the use of SPSS 26.0, the narrative competence of different populations was compared, and factors affecting narrative competence were determined through Pearson correlation analysis and multiple regression analysis.Results:A total of 361 valid questionnaires were included in this study, and there was significant differences in the narrative competence score between different ages, professional titles, working years, income levels, and whether they wrote parallel charts ( P<0.05). The total score of narrative competence of pediatric staffs was (147.13±18.76), and positively correlated with the total resilience score and the score of each dimension ( P≤0.001). The regression analysis showed that writing parallel charts and resilience could explain 53.10% of the variation in narrative competence ( P<0.001). Conclusions:Pediatric staff's narrative competence is at low or intermediate levels. Parallel chart writing and resilience training can improve narrative competence and promote a harmonious doctor-patient relationship.

Objective To explore the method and the clinical effect of minimally invasive treating ac-romioclavicular joint dislocation by modified technique bare-handed Tight Rope.Methods A retrospec-tive analysis was performed on 61 cases of acromioclavicular joint dislocation(35 males and 26 fe-males,aged 45.6±5.2 years),treated with minimally invasive internal fixation by modified technique bare-handed Tight Rope between June 2018 and November 2021 in our hospital.According to Tossy classification,21 of them were Tossy Ⅱ and 40 were Tossy Ⅲ.The clinical effect was evaluated by Karlsson criteria,and the shoulder function was assessed by using the Oxford shoulder joint and Con-stant-Murley scores.Results All patients were followed up 9～12 months(11.2 months on the average).Sixty of them were restored without re-dislocation,reaching 60 of excellence and an excellence rate of 98.36％.At the last follow-up,the Constant-Murley and Oxford shoulder joint scores were 95.65±2.32 and 12.92±0.81,both significantly better than before surgery(P<0.01),with the satisfaction rate of 96.74％.Conclusion The treatment of acromioclavicular joint dislocation with modified technique bare-handed Tight Rope is minimally invasive,stable,not easy to relocate,and friendly to acromiocla-vicular joint and subacromial structure.Moreover,the shoulder joint function is well-recovered after the surgery with satisfactory effect.
ABSTRACT
Objective:To investigate the correlation between triglyceride-glucose (TyG) index on admission and unfavorable outcomes of patients with moderate-to-severe traumatic brain injury (msTBI) at 6 months postinjury.Methods:A retrospective cohort study was conducted to analyze the clinical data of 277 patients with msTBI admitted to Affiliated Jiangyin Hospital of Nantong University from January 2019 to December 2022, including 208 males and 69 females, aged 18-88 years [(57.0±15.1)years]. Glasgow Coma Scale (GCS) scores on admission were 3-8 points in 168 patients and 9-12 points in 109. According to the Glasgow Outcome Scale-Extended (GOSE) assessment at 6 months after injury, there were 121 patients with unfavorable outcomes (GOSE≤4 points) and 156 with favorable outcomes (GOSE≥5 points). The following indicators of the patients were recorded, including gender, age, history of diabetes, cause of injury, admission GCS, GCS motor score (GCSM), pupillary light reflex, worst Marshall CT classification within the first 24 hours after admission, admission TyG index, Mean Amplitude of Glycemic Excursions (MAGE) within 24 hours after admission, GCSM decline≥2 points within 72 hours after admission, craniotomy or not after admission, and prognosis, etc. TyG index served as the exposure variable focused in this study, which was calculated with fasting triglycerides and fasting blood glucose within 24 hours after admission. The 6-month prognosis of the patients was designated as the outcome variable of the study. After the patients were divided into different groups according to the three quantiles of the TyG index and unfavorable or favorable outcomes, the univariate analysis was conducted on watch variables, and variables with statistically significant differences were included in directed acyclic graphs (DAGs) for further identification of confounding variables. Factors which were found with no statistical significance in the univariate analysis but might affect insulin resistance after injury according to the authors′ previous researches were also included in the DAGs analysis. Three Logistic regression models were designed (Model 1 without correction, Model 2 with core variables of International Mission for Prognosis and Analysis of Clinical Trials in Traumatic Brain Injury (IMPACT) corrected, and Model 3 with confounding variables screened by DAGs corrected) to analyze whether the TyG index was an independent risk factor for the prognosis of msTBI patients. The optimal Logistic regression model was selected and then restricted cubic spline (RCS) was employed to investigate the relationship between the TyG index and the unfavorable outcomes.Results:The univariate analysis suggested that there were significant differences in gender, history of diabetes, MAGE, GCSM decline, and prognosis among the three quantiles of the TyG index ( P<0.05 or 0.01). Significant differences in age, history of diabetes, GCSM, pupillary light reflex, Marshall CT classification, TyG index, MAGE and GCSM decline were observed between unfavorable and favorable outcome groups ( P<0.05 or 0.01). The results of Logistic regression analysis that identified the confounding variables that influenced the correlation between the TyG index and unfavorable prognosis with DAGs suggested that a high TyG index level was significantly correlated with unfavorable outcomes in msTBI patients. Moreover, Model 3 that was corrected with confounding variables screened by DAGs had an optimal goodness-of-fit and adaptability. Model 3-based further RCS analysis indicated that the risk of unfavorable outcomes following msTBI may increase approximately linearly with the increase in TyG index within a certain range (TyG index<9.79). Conclusions:A high TyG index level on admission is the identified as an independent risk factor for unfavorable outcomes of patients with msTBI at 6 months postinjury. As the TyG index level increases, the risk of unfavorable outcomes also rises and may show a linear increasing trend within a certain range (TyG index<9.79).
ABSTRACT
Restless legs syndrome (RLS) is a common sensorimotor disorder. Although it does not pose a threat to life, it seriously affects the quality of life of patients. RLS pathogenesis is still unclear, and its incidence is associated with a variety of risk factors, including genetic factors and non-genetic factors. Genetic factors involve more than 20 risk genes, such as meis homeobox 1 ( MEIS1), BTB domain containing 9 ( BTBD9), mitogen-activated protein kinase kinase 5 ( MAP2K5), and protein tyrosine phosphatase receptor type Db ( PTPRD). Non-genetic factors include regional age, gender, obesity, medical related diseases, neuropsychiatric diseases and drugs. This paper reviews the recent advance in risk factors and related pathogenesis of RLS to provide references for early prevention and treatment of the disease.
ABSTRACT
Purpose@#This study aimed to investigate whether nighttime elective surgery influenced the short-term outcomes and prognosis of hepatocellular carcinoma (HCC) patients. @*Methods@#The 1,339 HCC patients who underwent hepatectomy were divided into the daytime surgery group (8 a.m.–6 p.m., n = 1,105) and the nighttime surgery group (after 6 p.m., n = 234) based on the start time of surgery. The 1:2 propensity score matching (PSM) analysis was used to control confounding factors. The short-term outcomes of HCC patients in the 2 groups were compared before and after PSM. Factors associated with major complications (Clavien-Dindo grade, ≥III) and textbook oncologic outcomes (TOO) were separately identified by multivariable logistic regression based on variables screened via least absolute shrinkage and selection operator (LASSO). The Kaplan-Meier method was used to analyze overall survival (OS) and recurrence-free survival (RFS). @*Results@#TOO was achieved after surgery in 897 HCC patients. HCC patients in the nighttime surgery group had a higher body mass index (P = 0.010). After 1:2 PSM, the baseline characteristics of patients between the 2 groups were similar. Short-term outcomes in HCC patients were comparable both before and after PSM (all Ps > 0.05), as were TOO in the 2 groups before (P = 0.673) and after PSM (P = 0.333). In our LASSO-logistic regression, nighttime surgery was not an independent factor associated with major complications or TOO. Both groups also had similar OS (P = 0.950) and RFS (P = 0.740) after PSM. @*Conclusion@#Our study revealed the safety of nighttime elective hepatectomy for HCC patients.
ABSTRACT
Objective:To observe the expression of CD36 in hepatocellular carcinoma tissues and cell lines, and to investigate the effects of CD36 on the proliferation and migration abilities of human hepatocellular carcinoma cell lines and human hepatocellular carcinoma cell xenograft models in nude mice.Methods:Differences in the expression levels of CD36 transcripts in 371 hepatocellular carcinoma and paracancerous tissues were analyzed based on information from The Cancer Genome Atlas (TCGA) database. Cancer tissues and corresponding paracancerous tissues of 48 hepatocellular carcinoma patients who were diagnosed and underwent surgical treatment at the Affiliated Hospital of Yangzhou University from January 2019 to February 2021 were prospectively collected, and the levels of CD36 mRNA in the tissues were detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) method. Western blotting was used to detect CD36 protein levels in human hepatocellular carcinoma cell lines Huh7 and HCCLM3 and human normal liver cell line LO2. Plasmids containing CD36 interfering sequences and empty plasmids were transfected into Huh7 cells or HCCLM3 cells for sh-CD36 group and control group, respectively. The CCK-8 assay was used to detect the proliferation ability (expressed as absorbance value) of cells in each group at 0, 12, 24, 36, 48 and 60 h of culture, and the scratch healing assay and Transwell assay were used to detect the migration ability of cells in each group. The Huh7 cells of sh-CD36 group or control group were injected into the axillary subcutis of BALB/c nude mice, with 4 mice in each group, to construct nude mice models of human hepatocellular carcinoma xenografts; the long and short diameters of tumor were measured weekly after 1 week of inoculation, and the tumor volume was calculated. The nude mice were put to death after 5 weeks of inoculation, and the tumor specimens were collected and weighed; the tumor cell morphology was observed under the microscope, and the expressions of CD36 and Ki-67 proteins in the tumor tissues was detected by immunohistochemistry (IHC).Results:Analysis of the data from the TCGA database showed that the level of CD36 transcripts was higher in hepatocellular carcinoma tissues compared with that in paracancerous tissues (4.2±1.8 vs. 3.2±1.5, t = 2.28, P = 0.035). Tissues detection using qRT-PCR in 48 patients with hepatocellular carcinoma showed that the relative expression of CD36 mRNA in hepatocellular carcinoma tissues was higher than that in paracancerous tissues (0.76±0.26 vs. 0.48±0.23, t = 3.52, P < 0.001). Western blotting assay showed that CD36 protein level in Huh7 and HCCLM3 cells was higher than that in LO2 cells, which were (1.42±0.11) times and (1.68±0.16) times higher than LO2 cells, respectively (both P < 0.001). At the mRNA and protein levels, the CD36 of Huh7 and HCCLM3 cells in the sh-CD36 group was lower than that in the corresponding control group (both P < 0.001). CCK-8 assay showed that the proliferative ability of Huh7 cells and HCCLM3 cells in the sh-CD36 group was lower than that in the corresponding control group after 36 and 24 h of culture (both P < 0.01). Scratch healing assay showed that the scratch healing rates of Huh7 cells [(12±3)% vs. (30±5)%, t = 4.01, P < 0.001] and HCCLM3 cells [(15±4)% vs. (29±5)%, t = 4.16, P < 0.001] in the sh-CD36 group were lower than those in the corresponding control group at 48 h of culture; Transwell assay showed that the number of Huh7 cells [(46±6) cells/field of view vs. (88± 6) cells/field of view, t = 5.56, P < 0.001] and HCCLM3 cells [(42±5) cells/field of view vs. (82±7) cells/field of view, t = 5.34, P < 0.001] penetrating into the membrane in 24 h in the sh-CD36 group was less than that in the corresponding control group. Five weeks after subcutaneous injection, the tumor volume [(682±268) mm 3vs. (1 375±512) mm 3, t = 4.73, P = 0.006] and tumor mass [(432±95) mg/mouse vs. (871±109) mg/mouse, t = 6.57, P < 0.001] of nude mice injected with Huh7 cells of the sh-CD36 group were lower than those of nude mice injected with Huh7 cells of the control group; under the microscope, the density of tumor cells in transplanted tumor specimens of nude mice injected with Huh7 cells of the sh-CD36 group was lower than that in nude mice injected with Huh7 cells of the control group, and the expression levels of both CD36 and Ki-67 proteins were also low. Conclusions:CD36 expression is up-regulated in cancer tissues of hepatocellular carcinoma patients and human hepatocellular carcinoma cell lines Huh7 and HCCLM3, and it may associate with cell proliferation and migration of hepatocellular carcinoma. Knockdown of CD36 expression significantly inhibits the proliferation and migration abilities of hepatocellular carcinoma cells in vitro, and inhibits the tumors of human hepatocellular carcinoma cell xenograft models in nude mice.
ABSTRACT
【Objective】 To systematically evaluate the effects of various rehabilitation therapies, including hydrotherapy, rehabilitation robot, core stability training (CST), whole-body vibration training (WBV), repetitive transcranial magnetic stimulation (rTMS), sling exercise training (SET), task-oriented training (TOT) and virtual reality (VR), on motor dysfunction in children with spastic cerebral palsy, so as to provide a reference for the scientific selection of rehabilitation programs for children. 【Methods】 Randomized controlled trials (RCTs) of the 8 rehabilitation therapies in the treatment of motor dysfunction in children with spastic cerebral palsy were searched from various databases, including PubMed, The Cochrane Library, Web of Science, EmBase, CNKI, CBM, VIP, and WanFang Database, from database inception to December 2022. Two researchers independently conducted literature screening, data extraction, and literature quality evaluation. Network Meta-analysis was performed using ADDIS 1.16.6 software, and Stata 16.0 software was used for graphic representation. 【Results】 A total of 43 RCTs involving 2 722 children with spastic cerebral palsy were included in the analysis. The results of the network Meta-analysis indicated that WBV had the most significant effect in improving the GMFM-88 score (MD=18.56, 95%CI: 34.91 - 2.45, P<0.05). Rehabilitation robot had the most significant effect in improving dimensions D (MD=6.30, 95%CI: 8.44 - 4.41, P<0.05) and E (MD=10.03, 95%CI: 15.03 - 4.84, P<0.05) of the GMFM-88 score. Additionally, hydrotherapy showed the most significant effect in improving the BBS score (MD=11.24, 95%CI: 22.26 - 0.20, P<0.05). 【Conclusions】 For children with spastic cerebral palsy, WBV is the most effective rehabilitation therapy to improve gross motor function, rehabilitation robot is the most effective therapy for improving standing and walking function, and hydrotherapy is the most effective therapy for improving balance.
