Objective To summarize the reasons and management strategies of reoperation after oblique lateral interbody fusion(OLIF),and put forward preventive measures.Methods From October 2015 to December 2019,23 patients who under-went reoperation after OLIF in four spine surgery centers were retrospectively analyzed.There were 9 males and 14 females with an average age of(61.89±8.80)years old ranging from 44 to 81 years old.The index diagnosis was degenerative lumbar intervertebral dics diseases in 3 cases,discogenie low back pain in 1 case,degenerative lumbar spondylolisthesis in 6 cases,lumbar spinal stenosis in 9 cases and degenerative lumbar spinal kyphoscoliosis in 4 cases.Sixteen patients were primarily treated with Stand-alone OLIF procedures and 7 cases were primarily treated with OLIF combined with posterior pedicle screw fixation.There were 17 cases of single fusion segment,2 of 2 fusion segments,4 of 3 fusion segments.All the cases underwent reoperation within 3 months after the initial surgery.The strategies of reoperation included supplementary posterior pedicle screw instrumentation in 16 cases;posterior laminectomy,cage adjustment and neurolysis in 2 cases,arthroplasty and neuroly-sis under endoscope in 1 case,posterior laminectomy and neurolysis in 1 case,pedicle screw adjustment in 1 case,exploration and decompression under percutaneous endoscopic in 1 case,interbody fusion cage and pedicle screw revision in 1 case.Visu-al analogue scale(VAS)and Oswestry disability index(ODI)index were used to evaluate and compare the recovery of low back pain and lumbar function before reoperation and at the last follow-up.During the follow-up process,the phenomenon of fusion cage settlement or re-displacement,as well as the condition of intervertebral fusion,were observed.The changes in in-tervertebral space height before the first operation,after the first operation,before the second operation,3 to 5 days after the second operation,6 months after the second operation,and at the latest follow-up were measured and compared.Results There was no skin necrosis and infection.All patients were followed up from 12 to 48 months with an average of(28.1±7.3)months.Nerve root injury symptoms were relieved within 3 to 6 months.No cage transverse shifting and no dislodgement,loosening or breakage of the instrumentation was observed in any patient during the follow-up period.Though the intervertebral disc height was obviously increased at the first postoperative,there was a rapid loss in the early stage,and still partially lost after reopera-tion.The VAS for back pain recovered from(6.20±1.69)points preoperatively to(1.60±0.71)points postoperatively(P＜0.05).The ODI recovered from(40.60±7.01)％preoperatively to(9.14±2.66)％postoperatively(P＜0.05).Conclusion There is a risk of reoperation due to failure after OLIF surgery.The reasons for reoperation include preoperative bone loss or osteoporosis the initial surgery was performed by Stand-alone,intraoperative endplate injury,significant subsidence of the fusion cage after surgery,postoperative fusion cage displacement,nerve damage,etc.As long as it is discovered in a timely manner and handled properly,further surgery after OLIF surgery can achieve better clinical results,but prevention still needs to be strengthened.

OBJECTIVE: This study prospectively investigates the association between immunoglobulin G (IgG) N-glycan traits and ischemic stroke (IS) risk. METHODS: A nested case-control study was conducted in the China suboptimal health cohort study, which recruited 4,313 individuals in 2013-2014. Cases were identified as patients diagnosed with IS, and controls were 1:1 matched by age and sex with cases. IgG N-glycans in baseline plasma samples were analyzed. RESULTS: A total of 99 IS cases and 99 controls were included, and 24 directly measured glycan peaks (GPs) were separated from IgG N-glycans. In directly measured GPs, GP4, GP9, GP21, GP22, GP23, and GP24 were associated with the risk of IS in men after adjusting for age, waist and hip circumference, obesity, diabetes, hypertension, and dyslipidemia. Derived glycan traits representing decreased galactosylation and sialylation were associated with IS in men (FBG2S2/(FBG2 + FBG2S1 + FBG2S2): odds ratio ( OR) = 0.92, 95% confidence interval ( CI): 0.87-0.97; G1 ⁿ: OR = 0.74, 95% CI: 0.63-0.87; G0 ⁿ: OR = 1.12, 95% CI: 1.03-1.22). However, these associations were not found among women. CONCLUSION This study validated that altered IgG N-glycan traits were associated with incident IS in men, suggesting that sex discrepancies might exist in these associations.

OBJECTIVE: To observe the effects of moxibustion at "Baihui" (GV 20) and "Dazhui" (GV 14) at different time points on the serum level of β-endorphin (β-EP), substance P (SP) and expression of interleukin-1β (IL-1β) and cyclooxygenase-2 (COX-2) protein in brainstem in rats with migraine, and to explore the effect and mechanism of moxibustion in preventing and treating migraine. METHODS: Forty male SD rats were randomly divided into a blank group, a model group, a prevention+treatment (PT) group and a treatment group, 10 rats in each group. Except the blank group, the rats in the remaining groups were injected with nitroglycerin subcutaneously to prepare migraine model. The rats in the PT group were treated with moxibustion 7 days before modeling (once a day) and 30 min after modeling, while the rats in the treatment group were treated with moxibustion 30 min after modeling. The "Baihui" (GV 20) and "Dazhui" (GV 14) were taken for 30 minutes each time. The behavioral scores in each group were observed before and after modeling. After intervention, ELISA method was used to detect the serum level of β-EP and SP; the immunohistochemistry method was used to detect the number of positive cells of IL-1β in brainstem; the Western blot method was used to detect the expression of COX-2 protein in brainstem. RESULTS: Compared with the blank group, the behavioral scores in the model group were increased 0-30 min, 60-90 min and 90-120 min after modeling (P<0.01); compared with the model group, in the treatment group and the PT group, the behavioral scores were decreased 60-90 min and 90-120 min after modeling (P<0.01). Compared with the blank group, in the model group, the serum level of β-EP was decreased (P<0.01), while the serum level of SP, the number of positive cells of IL-1β in brainstem and the expression of COX-2 protein were increased (P<0.01). Compared with the model group, in the PT group and and the treatment group, the serum level of β-EP was increased (P<0.01), while the serum level of SP, the number of positive cells of IL-1β and the expression of COX-2 protein in brainstem were decreased (P<0.01, P<0.05). Compared with the treatment group, in the PT group, the serum level of β-EP was increased and COX-2 protein expression was decreased (P<0.05). CONCLUSION Moxibustion could effectively relieve migraine. The mechanism may be related to reduce the serum level of SP, IL-1β and COX-2 protein expression in brainstem, and increase the serum level of β-EP, and the optimal effect is observed in the PT group.

OBJECTIVE To explore and establish a long-term mechanism for rational control of intravenous fluids in hospitals. METHODS On the basis of the establishment of rules and regulations， through the exploration and implementation of the core technical strategy of “six-step method”， a new mode of intravenous infusion control was established. The contents of the “six-step method” were as follows： the first step was to sort out the diseases that did not require intravenous infusion； the second step was to sort out the alternative drugs/dosage forms； the third step was to sort out the alternative routes of infusion； the fourth step was to develop drug specifications； the fifth step was to explore the personalized medication needs of clinical departments； the sixth step was to develop a department-specific integrated infusion regimen. The utilization rate of intravenous fluids in inpatients and the average daily amount of intravenous fluids per bed in inpatients were used as the main indicators to evaluate the control effect. RESULTS The comparison of the average values of three months before and after the implementation of the “six-step” management mode in the department of thoracic surgery of our hospital showed that after management and control， the average utilization rate of intravenous fluids in inpatients decreased by 1.74%， the average daily use of intravenous fluids in inpatients per bed decreased by 0.30 bags/bottle， and the per capita use of infusion drugs under key control gradually decreased. CONCLUSIONS The “six-step” management mode can reduce the utilization rate of intravenous fluids in inpatients， and this management mode is practical and feasible.

Objective: To analyze the prevalence of dry and wet age-related macular degeneration (AMD) in patients with diabetes, hypertension and hyperlipidemia, and to analyze the risk factors for AMD. Methods: A population-based cross-sectional epidemiologic study was conducted involving 14,440 individuals. We assessed the prevalence of dry and wet AMD in diabetic and non-diabetic subjects and analyzed the risk factors for AMD. Results: The prevalence of wet AMD in diabetic and non-diabetic patients was 0.3% and 0.5%, respectively, and the prevalence of dry AMD was 17% and 16.4%, respectively. The prevalence of wet AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 0.5%, 0.3%, 0.2%, and 0.7%, respectively. The prevalence of dry AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 16.6%, 16.2%, 15.2%, and 17.2%, respectively. Age, sex, body mass index, and use of hypoglycemic drugs or lowering blood pressure drugs were corrected in the risk factor analysis of AMD. Diabetes, diabetes/hypertension, diabetes/hyperlipidemia, and diabetes/hypertension/hyperlipidemia were analyzed. None of the factors analyzed in the current study increased the risk for the onset of AMD. Conclusion There was no significant difference in the prevalence of wet and dry AMD among diabetic and non-diabetic subjects. Similarly, there was no significant difference in the prevalence of wet and dry AMD among subjects with hypertension and hyperlipidemia. Diabetes co-existing with hypertension and hyperlipidemia were not shown to be risk factors for the onset of dry AMD.

OBJECTIVES: To investigate the differences in non-suicidal self-injury (NSSI) behaviors between only-child and non-only-child adolescents with mood disorders. METHODS: A three-stage sampling method was used to perform a cross-sectional survey of 529 adolescents, aged 12-18 years, who had mood disorders and NSSI behaviors. These adolescents were sampled from the outpatient service of 20 mental hospitals in 9 provinces of China from August to November 2020. A self-made questionnaire was used to collect general demographic data. The Functional Assessment of Self-Mutilation, Beck Scale for Suicide Ideation, Kessler Psychological Distress Scale, Stress Mindset Measure-General, Multidimensional Scale of Perceived Social Support, Multidimensional Students' Life Satisfaction Scales, and Rosenberg Self-Esteem Scale were used to collect the information on self-injury behaviors and psychological factors in these adolescents. RESULTS: A total of 529 adolescents with mood disorders and NSSI behaviors were surveyed, among whom 375 were only-child adolescents and 154 were non-only-child adolescents. Compared with the non-only-child group, the only-child group had a significantly higher total score of Functional Assessment of Self-Mutilation (P<0.05) .The type and frequency of self-injury in the only-child group were significantly higher than those in the non-only-child group (P<0.05). Psychological analysis showed that compared with the non-only-child group, the only-child group had a significantly lower score of self-esteem (P<0.05) and significantly higher scores of psychological distress and depressive symptoms (P<0.05). The multiple linear regression analysis showed that the score of suicidal ideation was positively correlated with the frequency of NSSI behaviors in both only-child and non-only-child adolescents with mood disorders (P<0.05); in the only-child adolescents, the level of self-esteem was negatively correlated with the frequency of NSSI behaviors (P<0.05), and the score of stress perception was positively correlated with the frequency of NSSI behaviors (P<0.05); in the non-only-child adolescents, the score of anxious emotion was positively correlated with the frequency of NSSI behaviors (P<0.05). CONCLUSIONS Among the adolescents with mood disorders and NSSI behaviors, the only-child adolescents tend to have a higher frequency of self-injury and poorer mental health, and therefore, the only-child adolescents with mood disorders and NSSI behaviors need more attention.

ObjectiveTo analyze the transcriptome characteristics of Xianlian Jiedu prescription （XLJDP） in the intervention of colorectal carcinoma by high-throughput cDNA-sequencing （RNA-seq）. MethodNinety male C57BL/6 mice were randomly divided into the control group， colorectal carcinoma due to dampness， heat， stasis， and toxin model group， and XLJDP group， with 30 mice in each group. Mice in the model group and XLJDP group were fed a high-fat diet and provided with azoxymethane and dextran sodium sulfate （AOM/DSS） for inducing colorectal carcinoma. Those in the XLJDP group were further treated with intragastric administration of 12.9 g·kg^-1 XLJDP since the day of modeling for 112 days. The colorectal tissues were collected from each group 4 h after the last drug treatment and stained with hematoxylin-eosin （HE） and methylene blue for observing the pathological changes. The total RNA was extracted from colorectal tissues for RNA-Seq-based transcriptome profiling， followed by gene oncology （GO） and Kyoto encyclopedia of genes and genomes （KEGG） pathway enrichment analysis and the screening and verification of differentially expressed genes. ResultCompared with the model group， XLJDP significantly relieved the colorectal congestion and edema and decreased tumor number and volume in mouse colorectal tissues. The methylene blue staining results indicated that XLJDP significantly suppressed the development of aberrant crypt foci （ACF，P<0.01）. As revealed by HE staining， XLJDP significantly alleviated the injury and dysplasia of colorectal tissues. Transcriptome analysis identified 615 differentially expressed genes （446 up-regulated and 169 down-regulated） between the model group and the blank group and 54 differentially expressed genes （29 up-regulated and 25 down-regulated） between the XLJDP group and model group. XLJDP mainly affected the expression of NIMA-related protein kinase 7 gene （Nek7， P<0.01）， Mucin 16 （Muc16， P<0.01）， SiahE3 ubiquitin protein ligase family member 3 （Siah3， P<0.01）， regenerating islet-derived protein 3-gamma （Reg3g， P<0.01）， RNA polymerase Ⅱ elongation factor-associated factor 2 （Eaf2， P<0.01）， transforming growth factor‐alfa gene （TGF-α， P<0.05）， secretoglobin family 1A member 1 （Scgb1a1， P<0.05）， family with sequence similarity 227 member B （Fam227B， P<0.05）， cytochrome P450 family 2 subfamily c polypeptide 40 （Cyp2c40， P<0.01）， and ankyrin repeat and EF-hand domain containing protein 1 （Ankef1， P<0.05）. Enrichment analysis showed that intestinal epithelial cell proliferation， metabolism of xenobiotics by cytochrome P450， and arachidonic acid metabolism signaling pathway were significantly enriched. ConclusionXLJDP is able to interfere with colorectal tumorigenesis and development due to dampness， heat， stasis， and toxin in mice， which has been proved by transcriptome analysis to be related to the regulation of metabolism-related pathways.

ObjectiveTo explore the effect of Xianlian Jiedu prescription （XLJDP） on the proliferation and glycolysis of human colorectal cancer HCT-116 cells and the underlying mechanism. MethodHCT-116 cells were cultured with XLJDP and then the survival rate was examined by methyl thiazolyl tetrazolium （MTT） assay. The effect on the HCT116 cell proliferation was detected by colony formation assay and 5-ethynyl-2′-deoxyuridine （EDU） incorporation assay. The amount of glucose consumed by HCT-116 cells was measured by glucose test kit， and the amount of produced lactic acid was determined by lactic acid test kit 48 h after the treatment with XLJDP. The expression of glycolysis-related proteins mammalian target of rapamycin （mTOR）， phosphorylated mTOR （p-mTOR）， glucose transporter 1 （GLUT1）， and lactate dehydrogenase （LDHA） was detected by Western blot. ResultThe half-maximal inhibitory concentration （IC₅₀） of XLJDP against HCT-116 cells was 6.82 g·L^-1. Compared with the blank group， XLJDP （1.625， 3.25， 6.50 g·L^-1） inhibited the proliferation of HCT-116 cells （P<0.05， P<0.01）. Moreover， compared with the blank group， XLJDP （1.625， 3.25， 6.50 g·L^-1） suppressed glucose uptake and lactic acid production in a dose-dependent manner （P<0.05， P<0.01）. The expression of p-mTOR/mTOR， LDHA， and GLUT1 was down-regulated by XLJDP （P<0.05， P<0.01）. ConclusionXLJDP can significantly inhibit the proliferation and the Warburg effect of glycolysis in colorectal cancer cells by regulating the mTOR signaling pathway and the down-regulating the expression of LDHA， GLUT1， and other key proteins and enzymes in glycolysis.

ObjectiveTo study the effect of Xianlian Jiedu prescription （XLJDP） on the activation of nuclear transcription factor-κB （NF-κB） signaling pathway induced by bromodomain-containing protein 4 （Brd4） in hypoxic microenvironment and to explore its mechanism in inhibiting the proliferation of colorectal cancer HT-29 cells. MethodThe human colorectal cancer HT-29 cells were cultured in a hypoxic incubator or normoxia incubator and treated with XLJDP at 0.8，1，1.2，1.6，3.2，6.4，and 12.8 g·L^-1 for 48 h， respectively. Following the detection of cell vitality using methyl thiazolyl tetrazolium （MTT） colorimetry， the effects of XLJDP （1.25，2.5，and 5 g·L^-1） on the cell mitochondrial membrane potential were determined using a fluorescent probe （JC-1）， and the apoptosis of colorectal cancer HT-29 cells was detected by flow cytometry. The cell colony formation assay and 5-ethynyl-2'-deoxyuridine （EDU） staining were conducted to test the proliferation of colorectal cancer HT-29 cells. The Western blot was carried out to measure the expression levels of Brd4 and its downstream relevant proteins such as c-Myc and hexamethylene bisacetamide-inducible protein 1 （HEXIM1）， as well as the effects of XLJDP on related proteins in the NF-κB signaling pathway. ResultCompared with the blank control group， XLJDP at 0.8，1，1.2，1.6，3.2，6.4，and 12.8 g·L^-1 inhibited the vitality of colorectal cancer HT-29 cells （P<0.05 ， P<0.01）， with the median inhibitory concentration （IC₅₀） under the hypoxic condition higher than that under the normoxia condition. Compared with the blank control group， XLJDP at 1.25，2.5，and 5 g·L^-1 significantly decreased the mitochondria membrane potential， enhanced the apoptosis （P<0.05，P<0.01）， and lowered the number of cell colonies and also the EDU-positive cells （P<0.05， P<0.01）. The results of Western blot showed that compared with the blank control group， XLJDP at 1.25，2.5，and 5 g·L^-1 down-regulated Brd4， c-Myc， p-NF-κB p65， and p-IκBα protein expression to varying degrees and up-regulated the expression of HEXIM1 （P<0.05， P<0.01）. ConclusionIn the hypoxic microenvironment， XLJDP inhibits the proliferation of colorectal cancer HT-29 cells regulated by Brd4， which may be related to its inhibition of the activation of NF-κB signaling pathway.
