Objective To investigate the prognostic value of fever burden in traumatic brain injury (TBI) patients.Methods A retrospective analysis of 355 TBI patients admitted to the emergency department and intensive care unit from November 2010 to October 2012 was performed,and the Glasgow outcome scale (GOS) was followed-up 6 months after the injury.The patients were divided into two groups according to the GOS:good outcome group (4 to 5) and poor outcome group (1 to 3).Relevant clinical findings were studied by statistical description,logistic regression analysis,Spearman correlation analysis and ROC curve analysis.Results Fever burden level was continuously increased with the decrease of GOS from score 5 to 2,except for score 1 of GOS,which was corresponding to a significant lower fever burden.There were significant differences in age,pupil reactivity,Glasgow coma scale (GCS) and fever burden between two groups (P ＜ 0.05).Compared to the good outcome group,the poor outcome group was featured with more advanced average age (P =0.000),poorer pupil reactivity (P =0.000),lower GCS score (P =0.000) and higher fever burden level (P =0.000).Univariate logistic regression analysis suggested that age,GCS,pupil reactivity and fever burden level (OR 1.166,95％ CI:1.117-1.217) were associatedwith poor outcome.The fever burden level and the other independent prognostic predictors as age,GCS and pupil reactivity were further included in the multivariate logistic regression model,and the adjusted OR of fever burden level was 1.098 (95％ CI:1.031-1.169,P =0.003).ROC curve analysis showed the respective AUC for fever burden was 0.713 (95％ CI:0.663-0.760).The relevant analysis revealed a significant negative correlation between the fever burden and the GOS score (r =-0.376,95％ CI:-0.462--0.283,P =0.000).Conclusions Fever burden can be considered as an independent predictor of poor outcome of patients with TBI.The TBI patients with early onset of high levels of fever burden will have increased poor outcome risk.

Objective To explore the effects of high-dose ambroxol hydrochloride (Mucosolvan) on pulmonary protection and anti-inflammatory in traumatic brain injury patients treated by mild hypothermia.Methods From June 2008 to June 2012,40 elderly traumatic brain injury patients aged 60-70 years treated by mild hypothermia in our hospital were selected.Patients were randomly divided into two groups:low-dose ambroxol hydrochloride group and high dose ambroxol hydrochloride (n=20,each).Patients in low-dose ambroxol hydrochloride group were treated with ambroxol 30 mg plus saline infusion,3 times/day; while patients in high-dose ambroxol hydrochloride group were treated with ambroxol 300mg plus saline infusion,3 times/day; both groups were treated for 7 days.The changes of characteristic and quantity of sputum,PaO2and PaO2/FiO2,and serum TNF α level were analyzed at day 1,3,7.Duration of mechanical ventilation,tracheotomy proportion,and mortality were compared between the two groups 3 months after treatment.Results At day 3-7 after the intervention,the sputum got thinner and less,and more easy to suck in highdose group than in low-dose group (thin sputum proportion:75％ vs.40％,P =0.025; clean proportion by once suction:65％ vs.25％,P=0.011).The improvement of PaO2,PaO2/FiO2 were more significant in high dose group than in low dose group (PaO2 ∶ 3d,(92.3±12.3) mm Hg vs.(83.3±15.2) mm Hg,P=0.046;7d,(95.9±12.5) mm Hgvs.(87.1±11.7) mm Hg,P=0.028;PaO2/FiO2∶3d,(290.8± 15.8) mmHgvs.(221.8± 16.4) mm Hg,P=0.000;7d,(296.3±16.9)mm Hg vs.(238.4±15.0) mm Hg,P=0.000).Serum concentrations of TNF α was lower in highdose group than in low dose group [3d,(54.1± 4.9) ng/L vs.(71.4± 5.6) ng/L,P=0.000;7d,(35.1± 2.7) ng/L vs.(63.3±4.3) ng/L,P 0.000].Duration of mechanical ventilation was shorter and tracheotomy proportion was lower in high dose group than in low dose group [(116.8±18.7) hrsvs.(178.4±35.5) hrs,P=0.000; 25％ vs.60％,P=0.025].There was no significant difference in mortality between groups 3 months after treatment.Conclusions The application of high dose ambroxol can improve respiratory function,decrease duration of mechanical ventilation and tracheostomy proportion,and reduce the systemic inflammatory response in elderly traumatic brain injury patients treated by mild hypothermia,but without long-term survival benefit.

Conclusion: The summarized syndrome types of gastric cancer from this study are consistent with the clinical situations and would prove to be more referential for TCM syndrome differentiation diagnosis and treatment of gastric cancer.

Objective:To compare the effects of stromal cell-derived factor-1 (SDF-1 )and granulocyte colony-stimulating factor (G-CSF)on proliferation,migration,and odontoblastic differentiation of human dental pulp stem cell (DPSC)in vitro.Methods:DPSCs were cultured in vitro and treated with either 1 00 μg/L SDF-1 or 1 00 μg/L G-CSF.Cell counting kit-8 (CCK-8 )and colony-forming unit (CFU ) were used to detect the effect of SDF-1 and G-CSF on the proliferation ability of DPSC.Cell migration of DPSC was determined by wound healing assay and Transwell migration assay.The effects of SDF-1 and G-CSF on odontoblastic differentiation of DPSC were evaluated by alkaline phosphatase (ALP)staining, ALP activity and alizarin red S staining.The expression of odontoblastic-related genes such as dentin ma-trix protein 1 (DMP-1 )and dentin sialophosphoprotein (DSPP)were quantified by real-time RT-PCR. Results:SDF-1 and G-CSF promoted the proliferation of DPSC slightly,but the difference was not statis-tically significant.Wound healing assay showed that SDF-1 and G-CSF promoted cell migration of DPSC significantly (P<0.01 ),but there was no significant difference between the two factors.In Transwell migration assay,the number of migrated cells of the control group was 5 .0 ±1 .4 per sight,while the SDF-1 group was 24.3 ±6.8 per sight and the G-CSF group was 1 1 .8 ±3.3 per sight,suggesting that cell migration of DPSC was improved significantly after being treated with SDF-1 or G-CSF,and SDF-1 was more effective than G-CSF (P<0.05 ).Significantly greater odontoblastic differentiation potential was found in SDF-1 group and G-CSF group based on the ALP staining.Higher ALP activity,more mineralization nodule formation and higher expressions of DMP-1 and DSPP were also found after SDF-1 or G-CSF treatment.Conclusion:SDF-1 had no significant effect on the proliferation of DPSC,but could significantly promote cell migration and odontoblastic differentiation of DPSC.Its effect on DPSC was bet-ter than G-CSF.

SUMMARY To investigate the effect and feasibility of total laparoscopy to treat hepatolithiasis using gall-bladder-hepatic duct subcutaneous tunnel.Retrospective analysis was conducted of the case data of 11 pa-tients with hepatolithiasis who underwent total laparoscopic treatment using gallbladder-hepatic duct sub-cutaneous tunnel from January 2010 to October 2014.The operation time,blood loss,postoperative com-plications and recurrence of stones were recorded.All the cases completed the operation.The average hos-pital-stay was 9.2 days (range:3 -29 d).The average operation time was 298 min (range:225 -480 min).The average blood loss was 253 mL (range:50 -700 mL),and the average blood loss of liver re-section groups was 325 mL (range:200 -700 mL).The average discharge time was 3.3 days (range:3 -5 d).The rate of postoperative residual stones was 36.4% (4 /11).We extracted stones with chole-dochofiberscope via T-tube sinus six weeks after operation.One case developed biliary leakage,and healed through adequate drainage and the T-tube was pulled out after one month.There was no periopera-tive mortality.All the cases were followed up and the mean follow-up was 22 months (range:2 -51 months).The anastomotic stenosis of gallbladder-hepatic duct was found in one case.But we got a good therapeutic result with performed gallbladder chemical ablation with 95% ethanol.No recurrence of hepa-tolithiasis was found.As a choice for minimally invasive method to hepatolithiasis using gallbladder-he-patic duct subcutaneous tunnel,total laparoscopy is a safe and feasible procedure.

Objective To explore and evaluate an extracorporal method for inducing magnetic capsule endoscopy into small intestine. Methods 40 patients receiving magnetic capsule endoscopy were randomly divided in two groups: the control group: doctors stopped manipulating capsule after the examination of stomach, and the capsule entered small intestine by the natural gastrointestinal motility; and the study group: after the examination of stomach, the patient lay on the right side, doctors moved the capsule to the pylorus, and then moved magnetic ball to induce capsule into small intestine. Gastric inspection time, gastric residence time, small intestine transit time and the completion rate were compared between the two groups. Results The average time for checking stomach was (32.50 ± 11.71) min in control group and (31.75 ± 9.12) min in study group respectively, and the difference was not significant (P > 0.05). After the observation of stomach, the gastric residence time in the control group was (40.60 ± 21.43) min, and the completion rate was 40%, while the average gastric residence time in the study group was (13.55 ± 9.62) min, and the completion rate was 75%. The difference between the two groups was statistically significant (P < 0.05). Small intestine transit time was (329.25 ± 90.00) min in the control group and (342.00 ± 89.80) min in the study group, and the difference was not significant (P > 0.05). Conclusion By doctors moving magnetic ball and the patient lying on the right side after the observation of stomach, gastric residence time could be reduced and the completion rate could be elevated obviously.

To observe in vitro the effect of rat drug serum on the proliferation of HSC-T6 hepatic stellate cells in the pharmacokinetic model for determining peoniflorin in Fufang Biejia Ruangan tablet, in order to discover the rational daily administration frequency of Fufang Biejia Ruangan tablet. Fufang Biejia Ruangan tablet was orally administered to rats with different daily administration frequency. Their blood was collected from veins behind eye sockets at different time points before the administration and after the first administration, in order to determine the concentration of peoniflorin in blood plasma and the effect of rat drug serums on the proliferation of HSC-T6. A comprehensive analysis was made on the relationship between pharmacodynamics and pharmacokinetics to determine the rational daily administration frequency of Fufang Biejia Ruangan tablet. The results showed a good correlation between the inhibitory effect of Fufang Biejia Ruangan tablet-contained serum on HSC-T6 and the concentration of peoniflorin in blood. The two-time administration group showed higher pharmacologic and pharmacokinetic AUCs than one-time administration and three-time administration groups. In conclusion, Fufang Biejia Ruangan table is recommended to be taken twice a day for treating liver fibrosis in chronic hepatitis.

OBJECTIVETo study the effects of environmental enrichment on neuron proliferation, learning and memory ability and motor ability in neonatal rats with hypoxic-ischemic brain damage (HIBD).

METHODSOne hundred and eight 7-day-old Sprague-Dawley rats were randomly divided into three groups: sham operation (CON group), HIBD and intervention group. HIBD model was prepared according to the classic Rice-Vannucci method. Environmental enrichment was administered for the rats in the intervention group after HIBD inducement. Behavioral tests (Water maze test, Suspension test and Slope test) were performed and the number of neural cells in the left hippocampus was examined 7, 14 and 28 days after intervention.

RESULTSThe pyramid cells in the hippocampus CA1 area in the HIBD group were significantly less than in the CON group at 7, 14 and 28 days (P<0.05). The number of pyramid cells in the hippocampus CA1 area in the intervention group was significantly higher than in the HIBD group (P<0.01) at 7, 14 and 28 days. The hidden platform escape latency period (EL) in the Water maze test was significantly more prolonged and the cross-platform number within 2 minutes was significantly less in the HIBD and the intervention groups than in the CON group at all observed time points (P<0.01). The EL was significantly shorter and the cross-platform number within 2 minutes was significantly higher in the intervention group than in the HIBD group at all observed time points (P<0.01). The maintain time and score in the Suspension test were significantly lower and the time in the Slope test was significantly more prolonged in the HIBD and intervention groups than in the CON group at 7, 14 and 28 days (P<0.01). An increased maintain time and score and a decreased time in the Slope test were found in the intervention group compared with the HIBD group at 14 and 28 days (P<0.01).

CONCLUSIONSEnvironmental enrichment can improve motor function, learning and memory ability, and promote the repair and proliferation of neurons in neonatal rats with HIBD.
