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 study the gait characteristics of spastic diplegia cerebral palsy children. Methods The gaits of 26 spastic diplegia cerebral palsy children were analyzed. Results and Conclusion There were significant differences between spastic diplegia cerebral palsy children and 20 healthy subjects in both temporal-spatial parameters (stride time, stride length, stance time (%), cadence, speed) and kinematic parameters (the joint angle of hip, knee, ankle occurring at heel-contact, toe-off, the maximal extension in stand phase, maximal flexion in swing phase and total excursion on sagittal plane).

Human mammaglobin (hMAM) is a recently discovered breast tissue specific protein with a high sensitivity and specificity. The expression of hMAM in breast cancer and its relationship with breast cancer indicate that hMAM is a novel breast specific marker that can induce cytotoxic actions from immune system and therefore may have great potentials in breast cancer treatment.

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.

Objective To develop a new method for detection of anti-dsDNA antibodies Methods Plasma double stranded DNA were used as antigen substrate and derived with fluorescence thiazole orange homodimer Capillary electrophoresis with laser induced fluorescence was used for the detection of anti dsDNA antibodies of patient with Systemic lupus erythematosus (SLE) Results 23 out of 40 patients with SLE were positive(57 5%); 1 out of 25 patients with other autoimmune disease were positive; none of 45 controls were positive Comparison of this assay with Farr and dot immunobinding assay(DIBA)shows that CE LIF was more sensitive than DIBA and more specific than Farr Conclusions The assay was rapid, simple and reproducible CE LIF may become a routine assay for determination of anti dsDNA antibodies

and each of the resistant strains was resistant at least to 5 antibiotics.13 strains out of the 28 harbored plasmids ranging from 1 to 6 in number and 105 Md to 2.7 Md in molecular weight.The plasmid with 50 Md was the most popular one in this study,which may be the epidemic plasmid in the urologic unit.It was also found that 2 different species of bacteria isloated from the patients with infection of the urinary tract showed identical plasmid profile,which indicates that these 2 patients may be associated with each other.

Objective To investigate the effect of brain ischemic preconditioning (IP) combined with traditional Chinese medicine three seven three alcohol saponin (PTS) on proliferation of endogenous neural stem cells and the mRNA expressions of delta opioid receptor (DOR),Bax,Bcl-2 in hippocampus at 7d post middle cerebral artery occlusion (MCAO).Methods The focal-focal ischemic tolerance models were established with twice suture method.80 SD rats were included and randomly divided into 5 groups:sham group,MCAO group,sham+ MCAO group,IP+ MCAO group,PTS+MCAO group (n=16 each).We chose 10 SD rats from each group to evaluate their neurological status,and made BrdU fluorescent immunolabeling.In addition,we chose the other 6 SD rats to detect the expression levels of DOR,Bax and Bcl-2 mRNA in ischemic region in hippocampusby using RT-PCR.Animals were given one set of BrdU injections (on day 6,three times,4h apart,50mg/kg) to label the proliferating cells.The neurological status was assessed by using Zea Longa neurological deficit scores at 7 days following cerebral infarction.Results Zea longa neurologic deficit scores in MCAO group and sham+ MCAO) group had significantly differences with IP+ MCAO group and PTS+ MCAO group respectively at 7d post MCAO(P＜0.01).There was no significant differeuce in Zea-longa neurologic deficit scores between MCAO group versus sham+ MCAO group,and IP+ MCAO group versus PTS+ MCAO group(P＞0.05).The number of BrdU+ ceils in hippocampus had significant differences between IP+ MCAO and PTS+ MCAO groups at 7d post MCAOand three groups of sham,MCAO and sham+ MCAO respectively (P＜0.01).There was no difference in the number of BrdU+ cells between MCAO versus Sham + MCAO groups and IP + MCAO versus PTS+MCAO groups(P＞0.05).DOR and Bcl-2 mRNA expression levels were higher and Bax mRNA expression level was lower in IP+ MCAO group than in MCAO,Sham+ MCAO and PTS+MCAO groups (P＜0.01).There were no significant differences in DOR,Bcl-2 and Bax mRNA expressions among MCAO,Sham + MCAO and PTS + MCAO groups (P＞ 0.05).Conclusions Acute cerebral infarction can induce the proliferation of endogenous neural stem cells in hippocampus in SD rats.IPC can facilitate the proliferation of endogenous neural stem cells in hippocampus afteracute cerebral infarction,improve the symptoms of neurologic dysfunction,increase DOR and Bcl 2 mRNA expressions,and reduce Bax mRNA expression in SD rats.PTS can facilitate the proliferation of endogenous neural stem cells in hippocampus after acute cerebral infarction in SD rats,and improve the symptoms of neurologic dysfunction,but it has no influence on the expressions of DOR,Bcl-2 and Bax mRNA.
