Objective To study clinical value of multiple organ dysfunction syndrome (MODS) score to evaluate prognosis for patients with liver failure. Methods A total of 189 patients with liver failure were recruited into the study, 125 deaths and 64 survivals. Their vital sign, platelets count (PLT), prothrombin time (PT) and international normalized ratio of PT (INRPT), fraction of inhaled oxygen (FiO2), arterial oxygen partial pressure (PaO2), serum levels of total bilirubin (TB), albumin (ALB), creatinine (Cr), pressure-adjusted heart rate (PAHR), glasgow coma score (GCS), degree of aacitic fluid (DAF) and stage of hepatic encephalopathy (SHE) were evaluated within 24 hours after admission. Each of the patients scored according to the criteria of MODS score, Child-Turcotte-Pugh (CTP) score and model for end-stage liver disease (MELD) score. Difference in MODS score between death and survival groups was compared and accuracy of prognosis of MODS score, CTP score and MELD score were evaluated by the area under receiver operating characteristic (ROC) curve. Survival time of patients in the two groups classified by their MODS scores was compared with Kaplan-Meier (K-M) survival curve. Results There was significant difference in PT, INRPT, PaO2, Cr, GCS, SHE between death and survival groups, but there was no difference in TB, ALB, PLT, FiO2, PHAR and DAF between them. Mean score of MODS in death group (9±2) was significantly higher than that in survival group (7±1) (t=9.076, P<0.01). The area under ROC curve (AUC) of MODS score (0.814) was close to that of MELD score (0.827), but higher than that of CTP score (0.714). There was significant difference in survival time between the varied groups classified by MODS score (χ2=72.451, P<0.01). Conclusions Clinical value of MODS score is equivalent to that of MELD score in evaluating prognosis for patients with liver failure, even better than that of CTP score, which can be used to evaluate short-term prognosis for patients with liver failure.

Objective:To investigate the association of pretherapeutic neutrophil, lymphocyte, monocyte, and serum albumin levels with nasopharyngeal carcinoma (NPC) prognosis in 401 patients. Methods:This study involved 401 NPC patients recently diagnosed and admitted in Sun Yat-sen University Cancer Center, China. Laboratory variables, such as immunology-related parameters and albumin level prior to treatment, were analyzed. The overall survival and disease-free survival rates were determined using the Kaplan-Meier method and were then compared using the log-rank test. Univariate and multivariate analyses were performed using the Cox proportional hazards model to identify prognostic factors. Results:Patients with neutrophil counts>5.20×109/L (n=172) had significantly lower overall survival and disease-free survival rates compared with those with neutrophil counts≤5.20×109/L (n=229) (P=0.014, P=0.009). In the 401 NPC cases, patients with high albumin levels (>43.00 g/L;n=253) had significantly higher overall survival (P=0.000) and disease-free survival (P=0.006) rates compared with those with low albumin levels (≤43.00 g/L;n=148). Multivariate analysis showed that the neutrophil level is an in-dependent risk factor for disease-free survival, whereas the albumin level is a strong independent prognostic factor for overall survival. Conclusion:The pretherapeutic neutrophil and albumin levels are independent prognostic factors for survival in NPC patients.

BACKGROUND:Cerebral ischemia tolerance can promote proliferation of autologous neural stem cells in the hippocampus of cerebral infarction rats, but panaxtrial saponins effects on the proliferation of autologous neural stem cells in the brain have not been reported. OBJECTIVE:To explore the relationship of panaxtrial saponins, ischemic preconditioning and proliferation of endogenous neural stem cells in the hippocampus of rats at 7 days after cerebral infarction, and to observe the effect on neurobehavioral scores of rats after cerebral infarction. METHODS:Fifty Sprague-Dawley rats were included and randomly divided into five groups:sham group, ischemia group, ischemic control group, ischemic preconditioning group, and panaxtrial saponins group. In the latter four groups, acute models of cerebral infarction were established using Zea-Longa method. In the sham group, only an incision was made on the neck. The focal-focal ischemic tolerance models were established with twice suture method in the ischemic preconditioning and panaxtrial saponins groups. Sham operation was instead of ischemic preconditioning in the ischemic control group. In the panaxtrial saponins group, rats were given intraperitoneal injection of 100 mg/kg panaxtrial saponins at 7 days before modeling. RESULTS AND CONCLUSION:After 7 days of cerebral infarction, the neurobehavioral score and the number of neural stem cells in the hippocampus were significantly increased in the ischemia group (P<0.01);compared with the ischemia group, the neurobehavioral scores were lowered in the ischemic preconditioning and panaxtrial saponins groups (P<0.01), while the number of neural stem cells in the hippocampus was increased (P<0.01). However, there was no difference between the ischemic preconditioning and panaxtrial saponins groups (P>0.05). In addition, differences in the neurobehavioral scores and the number of neural stem cells in the hippocampus were insignificant between the ischemic control group and ischemia group (P>0.05). These findings indicate that panaxtrial saponins can play a role similar to ischemic tolerance, and thus improve neurologic impairment in rats with cerebral infarction.

Chinese Journal of Tissue Engineering Research 2014;(40):6459-6463
BACKGROUND:Thoracic vertebrae connected with the ribs of corresponding segments constitute the thorax. Because of thoracic vertebrae deeply and complicated structure, it is difficult to operate or to expose thoracic vertebrae completely. The traditional anterior ways can thoroughly remove the focus and achieve a good internal fixation, but this treatment needs to cut the rid. The surgeon discovered in years of clinical practice that distraction of intercostal space without cutting off the ribs could completely remove the focus and achieve fixation and fusion. OBJECTIVE:To explore the feasibility, advantages and disadvantages of anterior plate fixation and autologous bone graft fusion in the repair of thoracic spinal tuberculosis.
METHODA total of 30 cases of thoracic spinal tuberculosis were enrol ed. On the base of traditional thoracic spinal anterior surgical approach, the rib was reserved. Anterior distraction device was used to open the ribs for clearance and to move the focus of thoracic spinal tuberculosis. Autologous ilium was obtained and subjected to fusion and anterior plate fixation. Visual Analog Scale, Oswestry Disability Index, Frankel grade and Bridwel bone healing rating were used before and after treatment.
RESULTS AND CONCLUSION:A total of 30 patients were fol owed up for 3-60 months. The bone healing (class A) was seen, but no fistula formation was visible. Nerve compression symptoms were improved, without aggravating cases. Postoperatively, the average Cobb angle correction was 10.32°. After 6 months, imaging revealed bone fusion of affected vertebral body. After 18 months, the vertebral height was not lost obviously, no recurrence of vertebral tuberculosis. These results indicated that anterior intercostal space without cutting ribs exposed clearly, showing a large space, where can meet the requirement of first-stage debridement fixation and fusion in the repair of thoracic tuberculosis. The pathological changes were visibly clear;the focus was thoroughly removed, and the ribs were reserved. The outcomes are identical to rib resection. Simultaneously, autogenous iliac trilateral cortex has good supporting effects. Loose cancellous bone mesh has good osteogenesis and is helpful to bone healing.
