ABSTRACT
The incidence of spinal infections,a relatively rare infectious disease,is on the rise due to the empirical use of antibiotics that increases the chances of infection with drug-resistant bacteria,as well as advances in testing technology that have led to an increase in detection rates.Identifying the type of pathogen to target antibi-otics is the key to treatment.However,conventionaldetection methods have low detection rates and are time-consum-ing,which are not conducive to the rapid and accurate diagnosis of spinal infection.Metagenomics next-generation sequencing(mNGS)is a detection technique that can sequence all nucleic acid fragments in samples,the emer-gence of which subverts traditional detection methods and plays an important role in the diagnosis and treatment of spinal infections.This article summarizes the application of mNGS in the diagnosis and treatment of spinal infection.
ABSTRACT
Objective:To preliminarily explore the clinical value of three-dimensional ultrasound fusion imaging(3DUS FI) visualization technology in guiding precise needle placement during thermal ablation of hepatocellular carcinoma (HCC).Methods:A total of 56 HCC patients (59 lesions)who underwent 3DUS FI guided thermal ablation were retrospectively analyzed in the First Affiliated Hospital of Sun Yat-sen University from November 2019 to December 2021. All patients were collected with three-dimensional ultrasound volume image before ablation which were fused with real-time two-dimensional ultrasound image for registration, and then the tumor and the safety margin of 5 mm were segmented and marked. Finally, the thermal ablation was performed under three-dimensional visualization. Contrast-enhanced CT/MRI was performed 1 month after thermal ablation to evaluate whether the lesion was completely ablated and measure the ablative margin, and the relationship between ablative margin and the incidence of local tumor progression (LTP) was also analyzed.Results:During the ablation, all lesions could be successfully registered and displayed in three-dimension. Postoperative contrast-enhanced ultrasound showed that all lesions were completely ablated. A total of 37 lesions could be evaluated for ablative efficacy and ablative margin based on contrast-enhanced CT/MRI 1 month after themal ablation, of which 32 (86.5%) lesions achieved complete ablation and obtained at least 5 mm ablative margin. During the follow-up period, LTP was occurred in 4 lesions, 3 of the lesions occurred at the ablative margin< 5 mm. Both 1-year and 2-year cumulative LTP rates were all 7.1%. None of patients had serious complications or deaths associated with thermal ablation.Conclusions:3DUS FI real-time guidance technology is feasible and safe in visually guiding precise needle placement during thermal ablation of HCC.
ABSTRACT
Objective:To study the evolution of Traditional Chinese Medicine (TCM) syndromes of 171 cases of Kawasaki disease (KD) under the intervention of gamma globulin therapy based on factor analysis.Methods:A cross-sectional study. 171 cases of KD children hospitalized in the Department of Cardiology of Guangzhou Women's and Children's Medical Center from July 2019 to December 2020 were collected. All patients were treated with intravenous gamma globulin (2 g/kg) for 1 week. According to the results of the treatment with C-ball, 171 children with C-ball sensitive KD were selected to collect the four diagnostic data, and the representative syndromes of defensive level, qi level, yin level, and nutritive level were observed. Factor analysis was used to analyze the evolution of syndrome in 171 children with KD c-ball sensitivity.Results:The result of factor analysis showed that the KMO statistics of 171 children with c-ball sensitivity before treatment was 0.792, and Bartley test was significant ( P<0.01). 16 common factors were extracted, and 23 syndromes were screened, mainly including defensive level disorder, qi level disorder,nutritive level disorder,yin level disorder, heat stagnation and blood stasis syndrome. One week after treatment, the statistic of KMO test was 0.787, and Bartley test was significant ( P<0.01). 9 common factors were extracted, and 10 syndromes were screened, mainly including qi deficiency syndrome, yin deficiency syndrome and blood stasis syndrome. Conclusion:Before treatment, the TCM syndromes in KD C-cell sensitive children are mainly nutritive level disorder, defensive level disorder, qi level disorder yin level disorder, and heat stagnation and blood stasis syndrome; after treatment, the main TCM syndromes are mainly qi deficiency syndrome, yin deficiency syndrome and blood stasis syndrome.

ABSTRACT
Objective:To study the effects of silencing protein arginine methyltransferase 6 (PRMT6) gene on cell proliferation and migration of gastric cancer cell line MGC-803, and explore its related molecular mechanism.Methods:The expression levels of PRMT6 mRNA and protein in human normal gastric mucosa epithelial cell line GES-1 and human gastric cancer cell lines (AGS, SGC-7901, MGC-803) were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting. The gastric cancer cell line MGC-803 was divided into silencing control group (NC group), PRMT6 silencing group (si-PRMT6 group), nuclear factor-κB (NF-κB/p65) overexpression group (pcDNA-p65 group), si-PRMT6+ pcDNA-p65 group and PRMT6 silencing and matrix metalloproteinase 9 (MMP9) overexpression group (si-PRMT6+ pcDNA-MMP9 group). Western blotting was used to detect the protein expression levels of PRMT6, NF-κB/p65 and MMP9. CCK-8 kit and Transwell assay were used to measure cell proliferation and migration rates.Results:The results of qRT-PCR showed that the relative expression levels of PRMT6 mRNA in GSE-1, AGS, SGC-7901 and MGC-803 cells were 1.041±0.114, 2.141±0.132, 2.716±0.231, 2.825±0.300, and the difference among the four groups was statistically significant ( F=46.082, P<0.001). Compared with GSE-1 cells, PRMT6 mRNA expression levels were significantly increased in AGS, SGC-7901 and MGC-803 cells (all P<0.001). Western blotting results showed that the relative expression levels of PRMT6 protein in GSE-1, AGS, SGC-7901 and MGC-803 cells were 1.090±0.101, 2.847±0.331, 2.925±0.419 and 3.278±0.463, with a statistically significant difference ( F=22.683, P<0.001). Compared with GSE-1 cells, PRMT6 protein expression levels were significantly increased in AGS, SGC-7901 and MGC-803 cells, with statistically significant differences ( P=0.008; P=0.002; P=0.003). After 48 hours of silencing PRMT6 in MGC-803 cells, in NC group and si-PRMT6 group, the PRMT6 mRNA expression levels were 0.921±0.110 and 0.303±0.045, the PRMT6 protein expression levels were 1.032±0.105 and 0.289±0.043, the cell proliferation activities were 0.917±0.089 and 0.660±0.069, the cell migration rates were (89.122±5.109)% and (30.831±4.463)%, and the p-p65/p65 protein relative expression ratios were 0.947±0.143 and 0.285±0.023. The relative expression levels of PRMT6 mRNA and protein, cell proliferation activity, cell migration rate, protein relative expression ratio of p-p65/p65 in si-PRMT6 group were significantly lower than those in NC group, with statistically significant differences ( t=9.006, P<0.001; t=11.338, P<0.001; t=3.954, P=0.017; t=14.881, P<0.001; t=7.919, P<0.001). Western blotting results showed that the MMP9 protein relative expression levels in NC group, si-PRMT6 group, pcDNA-p65 group and si-PRMT6+ pcDNA-p65 group were 1.202±0.138, 0.318±0.018, 2.849±0.217 and 1.595±0.194, with a statistically significant difference ( F=127.410, P<0.001). Further pairwise comparison showed that the protein relative expression level of MMP9 in si-PRMT6 group was significantly lower than that in NC group ( P<0.001), while that in si-PRMT6+ pcDNA-p65 group was significantly lower than that in pcDNA-p65 group ( P=0.002). Then, MGC-803 cells were co-transfected with si-PRMT6 and pcDNA-p65 or pcDNA-MMP9 for 48 h. The cell proliferation activities in NC group, si-PRMT6 group, si-PRMT6+ pcDNA-p65 group and si-PRMT6+ pcDNA-MMP9 group were 0.923±0.054, 0.608±0.024, 0.818±0.035 and 0.807±0.029, with a statistically significant difference ( F=37.343, P<0.001). Further pairwise comparison showed that the cell proliferation activity of si-PRMT6+ pcDNA-p65 group or si-PRMT6+ pcDNA-MMP9 group was significantly higher than that of si-PRMT6 group (both P<0.001). The cell migration rates of above four groups were (85.195±3.176)%, (28.419±1.845)%, (60.490±7.231)% and (53.653±6.761)%, with a statistically significant difference ( F=59.672, P<0.001). Further pairwise comparison showed that the cell migration rate of si-PRMT6+ pcDNA-p65 group or si-PRMT6+ pcDNA-MMP9 group was significantly higher than that of si-PRMT6 group ( P=0.002; P=0.003). Conclusion:PRMT6 silencing can inhibit the proliferation and migration of gastric cancer cells MGC-803 via deactivation of NF-κB/MMP9 signaling pathway.
ABSTRACT
There are still some controversies about the timing of inguinal hernia surgery, the treatment of uterine round ligament, and the preference for laparoscopic or open surgery for women of childbearing age. For females of childbearing age, the recurrence rate of inguinal hernia is required low after herniorrhaphy. However, the number of samples available for observation is small. Currently, there is no international standard and guidelines for the treatment of female inguinal hernia. For women of childbearing age with fertility requirements, herniorrhaphy is more prudent. The authors elaborate on strategies for treatment of inguinal hernia in female of childbearing age.
ABSTRACT
Objective To study the impact of RAS status on prognosis of patients after liver resection for colorectal cancer liver metastases (CRLM).Methods The data of 545 consecutive CRLM patients who underwent liver resection at the Hepatopancreatobiliary Surgery Department I,Peking University Cancer Hospital between January 1st,2008 and December 31st,2016,were retrospectively reviewed.According to the inclusion and exclusion criteria,356 patients were eventually included into this study.There were 232 males and 124 females,with ages ranging from 21 to 83 years.The clinical and follow-up data of patients with wild-type and mutant RAS were compared.Survival was estimated by the Kaplan-Meier method,and the difference was compared by the log-rank test.Factors influencing survival of these patients were assessed by univariate and multivariate Cox regression analyses.Results There were 247 patients with wild-type RAS and 109 patients with mutant RAS,respectively.The median overall survival of patients with wild-type and mutant RAS were 74 and 30 months respectively.Compared with mutant RAS patients,wild-type RAS patients had significantly better cumulative survival and disease free survival rates (both P < 0.05).Multivariate Cox regression analyses revealed disease free interval from primary to metastases ≤ 12 months (HR =1.673,95% CI:1.016-2.637),largest hepatic tumor diameter > 5 cm (HR =1.717,95 % CI:1.102-2.637),and mutant RAS (HR =1.836,95% CI:1.322-2.550) were independent risk factors for patients with colorectal cancer liver metastases after hepatic resection.Conclusion Mutant RAS was a poor prognostic factor of survival after liver resection in CRLM patients
ABSTRACT
Objective:To compare the prognosis of patients with a single compared to multiple colorectal cancer liver metastases (CRLM) after hepatectomy.Methods:The clinical data of 490 patients with colorectal cancer liver metastases who underwent hepatectomy at Department of Hepatopancreatobiliary Surgery Ⅰ, Peking University Cancer Hospital & Institute from January 2006 to December 2016 were retrospectively studied. There were 314 males and 176 females. The median age was 58 years (range 21 to 83 years). There were 200 patients in the single liver metastasis group and 290 patients in the multiple liver metastases group. The tumor recurrence and survival outcomes on follow-up were analyzed. Survival curves were plotted using the Kaplan-Meier method. Both overall survival and disease-free survival between two groups were compared by the log-rank test. Univariate and multivariate Cox regression analyses were used to analyze independent risk factors of overall survival.Results:The 1-, 3-, 5-, 10-year overall survival rates for the single versus the multiple liver metastases groups were 92.5%, 58.6%, 51.0%, 38.8% versus 90.7%, 53.2%, 41.1%, 29.9%. The differences were significant ( P<0.05). The disease-free survival was also significantly better in the single than the multiple groups ( P<0.05). Cox multivariate analysis showed that right-sided primary colonic tumor, preoperative carbohydrate antigen 19-9 level ≥50 U/ml, and RAS mutant were independent factors influencing survival in patients with single liver metastasis; while primary colonic tumor N 1-2, liver metastases diameter ≥5 cm, and RAS mutant were independent factors influencing survival in patients with multiple tumors. If the three independent factors affecting overall survival of patients with multiple liver metastases were assigned 1 point for each factor, the number of patients with scores of 0, 1, 2, and 3 were 50, 145, 84, and 11, respectively. The long-term survival of patients with a low score (0, 1) was similar to those with a single liver metastasis (both P>0.05). However, patients with a high score (2, 3) showed significantly worse long-term survival when compared with patients with a single liver metastasis (both P<0.05). Conclusions:The prognosis of patients with single colorectal liver metastasis was better than those with multiple liver metastases after hepatectomy. For patients with multiple liver metastases with fewer associated risk factors, surgical resection could still result in long-term survival outcomes which were comparable to those patients with a single liver metastasis.
ABSTRACT
Objective:To construct and confirm a predictive model for the risks of cardiovascular diseases (CVD) with metabolic syndrome (MS) and its factors in Xinjiang Kazakh population.Methods:A total of 2 286 Kazakh individuals were followed for 5 years from 2010 to 2012 as baseline survey. They were recruited in Xinyuan county, Yili city, Xinjiang. CVD cases were identified via medical records of the local hospitals in 2013, 2016 and 2017, respectively. Factor analysis was performed on 706 MS patients at baseline, and main factors, age, and sex were extracted from 18 medical examination indexs to construct a predictive model of CVD risk. After excluding the subjects with CVD at baseline and incomplete data, 2007 were used as internal validation, and 219 Kazakhs in Halabra Township were used as external validation. Logistic regression discriminations were used for internal validation and external validation, as well as to calculate the probability of CVD for each participant and receiver operating characteristic curves.Results:The prevalence of MS in Kazakh was 30.88%. Seven main factors were extracted from the Kazakh MS population, namely obesity factor, blood lipid and blood glucose factor, liver function factor, blood lipid factor, renal metabolic factor, blood pressure factor, and liver enzyme factor. The area under the curve (AUC) for predicting CVD in the internal validation was 0.773 (95% CI 0.754-0.792). In the external validation, the AUC for predicting CVD was 0.858 (95% CI 0.805-0.901). Conclusions:The CVD risk prediction model constructed by 7 main factors extracted from Kazakh MS patients has high validation efficiency and can be used for risk assessment of CVD in Xinjiang Kazakh population.
ABSTRACT
OBJECTIVE@#To investigate the effect of Aurora kinase B (AURKB) silencing-induced autophagy on apoptosis of osteosarcoma 143B cells and the underlying molecular mechanisms.@*METHODS@#Human osteosarcoma 143B cells were transfected with Lv/shAURKB or the negative control vector Lv/shScrambled followed by treatment with chloroquine (CQ) for 24 h. Western blotting was performed to detect the protein expression levels of AURKB, P62, LC3, cleaved caspase-3, Bcl-2, and P-ULK1. Transmission electron microscopy and LC3 dual-label fluorescence method were used to trace the autophagosomes in 143B cells to assess cell autophagy, and the cell apoptosis was detected using flow cytometry and TUNEL assay. Co-immunoprecipitation assay was used to detect the interaction between AURKB and ULK1.@*RESULTS@#The ratio of autophagy-related proteins LC3 II/I and the number of autophagosomes were significantly increased in 143B cells after transfection with Lv/shAURKB ( < 0.05), which significantly increased the expression of cleaved caspase-3 and reduced the expression of Bcl-2 ( < 0.05). Combined treatment of the cells with Lv/shAURKB and the autophagy inhibitor chloroquine obviously restored the expressions of caspase-3 and Bcl-2 ( < 0.05). Transfection with Lv/shAURKB significantly increased the apoptosis rate of 143B cells ( < 0.05), and this effect was significantly antagonized by combined treatment with chloroquine ( < 0.05). AURKB silencing strongly activated the phosphorylation of the autophagy-initiating protein ULK1 in 143B cells ( < 0.05). The results of co-immunoprecipitation assay confirmed when AURKB was immunoprecipitated, ULK1 also precipitated.@*CONCLUSIONS@#Silencing AURKB can induce autophagy by activating ULK1 phosphorylation to promote apoptosis in 143B cells.
ABSTRACT
OBJECTIVE: To analyze the status and influencing factors of the health literacy(HL) of college students in a comprehensive university. METHODS: A total of 3 360 students from in a comprehensive university of Xinjiang Production and Construction Corps was selected using multi-stage stratified cluster random sampling method. The HL level of college students was investigated and evaluated with self-edited Xinjiang Construction Corps College Students Health Literacy Questionnaire. RESULTS: The HL level of college students was 17.1%. The HL level of medical students was higher than that of non-medical students(35.4% vs 10.0%, P<0.01). Logistic regression analysis results showed that among the medical students in grade three or four, those with medium and excellent academic achievement, and Han nationality had a positive effect on their HL level(P<0.01). Among the non-medical students, female and medicine related optional courses had a positive effect on their HL level(P<0.05). Students in the sophomore year had a negative effect on their HL level(P<0.05). CONCLUSION: There is a big difference in the level of HL between medical students and non-medical students. Medical college students and non-medical college students have different factors affecting HL, medical education is related to improving HL.

ABSTRACT
Objective@#To compare metabolic syndrome(MS)with Framingham risk score as predictors of cardiovascular disease(CVD)among Kazakhs population.@*Methods@#The participants were the residents who had been followed up for more than 5 years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting development of CVD using Cox regression and receiver operating characteristic curve.@*Results@#The incidence of CVD was 13.87%. The incidence of CVD was higher in the MS group than it in the non-MS group(21.59% vs 11.10%, P<0.001). The area under the receiver operating characteristic(ROC)curve of MS risk score was significantly larger than that of MS classification(0.727 vs 0.585, P<0.001); the area under the curve of MS risk score was close to that of Framingham risk score(0.732 vs 0.727, P=0.673). The association between CVD and each quintile of MS risk score was more significant than that between Framingham risk score and CVD under the same exposed condition(4.61, 9.33, 14.15, 22.29 vs 3.69, 6.36, 8.47, 16.99).@*Conclusion@#MS risk score that included age may be a better predictor of CVD among Kazakhs population.

ABSTRACT
Objective To analyze the risk factors and characteristics of bone metastases in patients with prostate cancer. Methods Patients who were diagnosed as prostate cancer by biopsy and histopathologic analysis between June 2006 and June 2016 were included in this study. The clinical data of the patients were reviewed, and the demographic data, laboratory examination results and Gleason score were recorded. The correlations between clinical factors and bone metastasis were analyzed, and the risk factors of bone metastasis were identified. Results A total of 585 patients were recruited in this study, including 228 with bone metastasis and 357 without bone metastasis. Of the patients with bone metastasis, the incidence of pelvic metastasis was the highest, accounting for 81.58%, followed by spin (63.16%) and rib (58.33%), and the incidence of clavicle metastasis was the lowest (14.47%). Logistic regression analysis showed that age 85.5U/L, prostate-specific antigen >79.88μg/L and Gleason score >7.5 were the risk factors of bone metastasis in prostate cancer. ROC curve analysis showed that the sensitivity of diagnosing bone metastasis was 56.1%, 66.7%, 68.4% and 56.1%, and the specificity was 56.6%, 81.8%, 70.0% and 65.3%, respectively for above 4 factors. Conclusions The most common site of bone metastasis in patients with prostate cancer is pelvis. Patients' age, concentrations of plasma ALP and PSA, and Gleason score are the risk factors for bone metastasis in patients with prostate cancer.

ABSTRACT
Adverse Drug Event(ADE)is a major factor threatening patient safety.For now,the ADE detecting in China mostly relies on spontaneous reporting,a method detecting only a small proportion of ADEs,instead of reflecting the real-world clinical medication safety.Global Trigger Tool (GTT)is a relatively new method for detecting ADEs.This paper described the GTT as an effective and practical method for detecting ADEs,by introducing the history of GTT development,GTT basic principles,operating procedures,current relevant researches and application at home and aboard and comparing with other ADE detection methods.The GTT can evaluate the clinical medication safety in various medical institutions.In particular,it can target specific clinical departments or certain people to detect ADEs for obtaining more evidences of clinical medication safety.That is the reason that we recommend medical institutions at all levels learn and use GTT.

Objective To investigate the effect of haplotype and linkage disequilibrium of PPARγgene rs3856806, rs12490265, rs1797912, and rs1175543 in patients with metabolic syndrome ( MS) in Kazakhs of Xinjiang.Methods MALDI-TOF-MS was used to detect PPARγgene rs3856806, rs12490265, rs1797912, and rs1175543 genotypes in 489 subjects ( including 245 MS and 244 controls ) .Results ( 1 ) The frequencies of rs3856806T, rs12490265A, rs1797912C and rs1175543G alleles for MS group in Kazakhs were all significantly lower than those for controls [ rs3856806T allele:12.53% vs 17.01%; rs12490265A allele: 31.84% vs 38.52%;rs1797912C allele:35.31%vs 43.24%;rs1175543G allele:40.61%vs 47.54%(all P<0.05)].(2)Significant linkage disequilibrium were observed between PPARγgene rs1797912 and rs1175543, rs12490265, and rs1175543 polymorphisms.(3)AGCC and GAAT were significantly different between MS and control group in Kazakhs(both P<0.05).(4) Carrying rs3856806T, rs12490265A, rs1797912C, rs1175543G was 0.267 times that of carrying rs3856806C, rs12490265G, rs1797912A, rs1175543A.Conclusions The PPARγgene rs3856806, rs12490265, rs1797912 and rs1175543 polymorphisms were associated with metabolic syndrome in Kazakhs.There were very strong linkage disequilibrium between PPARγgene rs1797912 and rs1175543, rs12490265 and rs1175543 polymorphisms, The AGCC haplotype and GAAT haplotype may serve as protective factors of metabolic syndrome.Carrying rs3856806T, rs12490265A, rs1797912C, and rs1175543G may confer lower risk of MS in Kazakhs.
ABSTRACT
Background and purpose:MicroRNA(miRNA) is a class of small non-coding RNA playing an important regulatory role in many tumors. This study investigated which miRNA might negatively regulate the expression of Aurora-B in osteosarcoma cells, and to lay the foundation for the further investigation of the effort and regulation of Aurora-B in osteosarcoma malignant phenotype.Methods:Bioinformatics prediction software (http://www.targetscan.org) and luciferase assays were used to investigate which miRNA might target to modulate the Aurora-B. Real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) and Western blot assay were used to further verify which miRNA could negative regulate the expression ofAurora-B gene.Results:Bioinformatics prediction showed let-7 family have the possibility to modulate the expression of Aurora-B; Luciferase assays showed thatAurora-B might be the target gene of let-7a/b/c/d/e/f/g/i; RTFQ-PCR and Western blot analysis testiifed that both the expression levels of Aurora-B mRNA and Aurora-B protein were signiifcantly decreased in Let-7a/g/i up-regulated U2-OS and HOS cells, compared to the cells in the negative control group; but in Let-7b/c/d/e/f up-regulated U2-OS and HOS cells, the expression levels of Aurora-B mRNA and Aurora-B protein have no signiifcant difference, compared to the cells in the negative control group.Conclusion:Let-7a/g/i may downregulate the expression of Aurora-B in human osteosarcoma cells.
