Objective To investigate the value of muhiple inflammatory cells and clinical score in early diagnosis and prognosis assessment of trauma sepsis risks.Methods This retrospective control study enrolled 209 severe trauma patients admitted from January 2010 and May 2016.White blood cell count,lymphocyte count and percentage,monocyte count and percentage,neutrophil count and percentage,ratio of neutrophil to lymphocyte count (N/L),acute physiology and chronic health evaluation (APACHE) Ⅱ score,sequential organ failure assessment (SOFA),improved early warning score (MEWS),Glasgow coma score (GCS),multiple organ dysfunction syndrome (MODS) score and lactic acid (LAC) were collected on the day of admission and 3,5,7 days after trauma.These data were applied to construct weighted and biological score models for early diagnosis and prognosis of traumatic sepsis.Receiver operating characteristic curve (ROC) was performed and area under the curve (AUC) was calculated to measure the value of the two models in early diagnosis and prognosis of sepsis.Results AUC of the weighted model combined by APACHE Ⅱ score,SOFA score and MEWS was 0.729 on the day of admission.AUC of the weighted model combined by inflammatory cells was 0.680 and AUC of the biological score model was 0.800 3 days after trauma (P ＜ 0.05).AUC of the weighted models combined by inflammatory cells was 0.798 and AUC of the biological score model was 0.812 5 days after trauma (P ＜ 0.05).AUC of the weighted models combined by inflammatory cells was 0.706 and AUC of the biological score model was 0.713 7 days after trauma (P ＞ 0.05).AUC of the biological score model had significant difference 3 days and 5 days after trauma (P ＜ 0.05).Of the weighted model combined by APACHE Ⅱ score,MODS score,GCS and LAC to evaluate the prognosis of sepsis,the AUC showed significant difference on the day of admission (0.838),3 days after trauma (0.878),5 days after trauma (0.947) and 7 days after trauma (0.936) (P ＜ 0.05).Conclusions Biological score possesses better effect on early diagnosis of sepsis 3 days after trauma.Weighted model combined by APACHE Ⅱ score,MODS score,GCS and LAC can effectively predict the prognosis of sepsis 5 days after trauma.

BACKGROUND/AIMS: Both sexual and physical abuse history have been reported to be associated with irritable bowel syndrome (IBS) in Western countries. The impact of abuse history in IBS patients in Asia remains unclear. We aim to determine the prevalence of abuse history, its associated psychological profiles, and sleep problems among IBS patients in Taiwan. METHODS: In total, 194 Rome III-defined IBS patients were invited to participate. Age- and sex-matched healthy carriers of chronic hepatitis B or hepatitis C without chronic abdominal symptoms were identified as disease-controls. We administered a validated questionnaire to evaluate bowel symptoms, physical/sexual abuse history, anxiety/depression (Hospital Anxiety and Depression Scale [HADS]), and sleep quality. RESULTS: IBS patients had a significantly higher prevalence of sexual abuse history than the disease-control group both before (16.5% vs 6.7%, P < 0.05) and after (16.0% vs 6.6%, P < 0.05) adolescence. These significant differences were mainly observed in women (13.4% vs 3.4%, P < 0.05). No difference was noted in history of physical abuse between the 2 groups. IBS patients with a history of sexual abuse had significantly higher HADS scores and higher frequencies of sleep difficulty than those without. CONCLUSIONS: In Taiwan, sexual abuse history was more prevalent in female IBS patients than controls. Sexual abuse history may contribute to higher anxiety/depression levels and sleep difficulties, which are commonly experienced in IBS patients. In Asia, abuse history should be obtained when approaching IBS patients to facilitate better management.

Objective To investigate any protective effect of transplanting EPhrinB2-modified bone marrow mesenchymal stem cells ( BMSCs) with a rat model of cerebral palsy. Methods BMSCs were isolated and cultured, then further modified by lentivirus-mediated transfection of the EPhrinB2 gene. Ninety-six Sprague-Dawley rats were randomly divided into a sham group, a solvent control group ( PBS group) , an empty lentivirus group ( EGFP group) and an EPhrinB2 recombinant lentivirus group ( EPhrinB2 group) , each of 24. A model of cerebral palsy was estab-lished in the rats of the PBS, EGFP and EPhrinB2 groups using hypoxic-ischemic encephalopathy. Seven days after the operation, the lateral ventricles of the PBS, EGFP and EPhrinB2 group mice were injected with phosphate-buff-ered saline solution, BMSCs or EPhrinB2-modified BMSCs respectively. EPhrinB2 protein expression in the hippo-campus was detected using immunohistochemistry 28 days after the operation. The neuron density in the CA1 region of the hippocampus was observed using hematoxylin and eosin staining, and any apoptosis of hippocampal neurons was detected using terminal deoxynucleotidyl transferase dUTP nick end labeling. The expression of nestin and CD31 in the hippocampus was observed using immunofluorescence assays. Morris water maze testing was also conducted to e-valuate changes in learning and memory ability. Results Compared with the other 3 groups, a significant increase in the expression of protein EPhrinB2 was observed in the hippocampuses of the EPhrinB2 group rats. The pathologi-cal changes in the hippocampus among the EPhrinB2 group were significantly less severe than those in the PBS and EGFP groups. The rate of apoptosis in the hippocampuses of the EPhrinB2 group was significantly lower than that of the other groups. Immunofluorescence showed that nestin- and CD31-positive cells were significantly more numerous in the EPhrinB2 group than in the others. In the water maze the average latency of the EPhrinB2 group was signifi-cantly shorter than those of the other groups. Conclusion Lentiviral-mediated EPhrinb2 transfection of BMSCs into the hippocampus can promote EPhrinB2 gene expression, promote angiogenesis and neuron differentiation, inhibit ap-optosis and accelerate the repair of injured nerves.

Objective:To investigate the characteristics of bacterial community in upper gastrointestinal tumors.Methods:The study population was patients with upper gastrointestinal tumors (esophageal cancer and gastric cancer). Gastroscopy was performed on the enrolled patients ( n=17), and the specimens were taken from the tumor sites. At the same time, non-tumor tissues more than 4 cm away from the tumor tissues were taken as the control. After total DNA was extracted and purified, high-throughput 16S DNA gene sequencing was used to detect the microbiota in tumor tissues and control tissues. Bioinformatics analysis was carried out and the differences between groups were compared. Results:16S DNA PCR showed that there was no significant difference in bacterial load between tumor tissues and control tissues. The α-diversity and β-diversity indexes showed that the community composition of the two groups was similar; the samples were discrete and the colony composition was different, but there was no significant difference between the two groups. The results of Venn diagram showed that there were more operational taxonomic units (OTUs) in non-tumor tissues than in tumor tissues (2 068 vs 1 358), indicating that the bacterial species in normal tissues were more abundant than those in tumor tissues. Compared with the control tissues, the percentages of Prevotellaceae ( Prevotella), Lactobacaceae ( Lactobacillus) and Fusobacteriaceae ( Fusobacterium) in tumor tissues were relatively higher (the average percentage was more than twice that of the control). Further paired comparison of the top ten bacteria in the family and genus abundance of the two groups of samples showed that Pseudomonas decreased significantly in tumor tissues at the family ( P=0.041) and genus ( P=0.041) levels, while Prevotella was significantly enriched in tumor tissues at the family ( P=0.031) and genus ( P=0.007) levels. Conclusions:The bacterial community in the tumor microenvironment of the upper gastrointestinal tumor changed, and the species enriched in the tumor site were mainly oral common anaerobic bacteria, such as Prevotellaceae ( Prevotella), Lactobacaceae ( Lactobacillus) and Fusobacteriaceae ( Fusobacterium), especially Prevotellaceae ( Prevotella).

Objective To investigate the characteristics of pulmonary function and pathological changes in rats with acute lung injury (ALI) and provide experimental basis for further study on the mechanism of ALI.Methods Twenty five male SD rats were randomly divided into the control group (n =5) and acute lung injury (ALI) group (n =20).Lipopolysaccharide (LPS) (4.5 mg/kg) were injected into the ALI group rats to establish the ALI rat model.The rats in control group were given 150 μl isotonic saline.At 12,24,48,and 72 hours after injury,lung function of the rats were tested by Buxco small animal lung function test system,including the dynamic lung compliance (Cdyn),forced vital capacity (FVC),functional residual gas (FRC),quasi static compliance (Cchord),100th millisecond expiratory volume (FEV100),and airway resistance (RI).In addition,the bronchoalveolar lavage fluid (BALF) was collected for detection of protein level and tumor necrosis factor (TNF-alpha)concentration.At the same time,the changes of lung tissues were recorded,and the pathological changes were observed by HE staining.Results Compared with the control group,Cdyn,FVC,FRC,and FEV100 in ALI group were significantly decreased at each time point after injury (P ＜0.05 or ＜0.01),while the airway resistance (R1) in ALI group was significantly increased at 24 and 48 hours after injury (P ＜ 0.01).There was no significant difference in quasi static compliance (Cchord) between two groups (P ＞ 0.05).The protein level and TNF-alpha concentration of BALF in ALI group were increased significantly (P ＜0.05 or ＜0.01) 12-72 hours after injury (P ＜ 0.01).Compared with the control group,the whole lung was dark red in ALI group 12 hours after injury,and the most serious bleeding occurred in the pulmonary hilum area with single or multiple hemorrhagic foci of different sizes.Multiple punctate and focal bleeding of different sizes were seen on the lung surface,which were radially distributed around the pulmonary hilum.The color of lung tissue was gradually restored to normal at 72 hours after injury.Under the light microscope,pulmonary interstitial edema,inflammatory cell infiltration,pulmonary vascular congestion and focal pulmonary hemorrhage were observed 12 h after injury,showing typical ALl pathological changes.The pathological changes were the most significant at 24 hours and reduced obviously at 72 hours.Conclusions A single intratracheal injection of LPS can induce typical ALI pathological changes.There is a similar trend between the pulmonary function indexes,lung pathology characteristics,and the protein level of BALF and proinflammatory cytokine level,suggesting that the pulmonary function test parameters can provide reference for evaluation of ALI.

Hepatocellular carcinoma is a common malignant disease in clinical practice, and portal vein tumor thrombosis (PVTT) is one of the important factors affecting the prognosis of hepatocellular carcinoma. PVTT has strong oncologic characteristics and is highly susceptible to extrahepatic metastasis, complicating portal hypertension, leading to gastrointestinal bleeding or liver failure and causing death. In this paper, we review the formation mechanism of hepatocellular carcinoma combined with PVTT in terms of local anatomy, hemodynamics, molecular biology and tumor microenvironment to provide effective reference for clinical treatment.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.
