ObjectiveTo evaluate the effect of lornoxicam used for craniotomy. Methods60 neurosugical patients, ASA physical I～II, were randomly allocated into three groups to receive normal saline in controlled group (GroupⅠ), lornoxicam 8 mg (Group Ⅱ) and lornoxicam 24 mg (Group Ⅲ) intravenously 10～15 min before anesthesia. The end-tidal concentration of isoflurane was measured. The volumes of bleeding, transfusion, fluid infusion and urine were recorded. The time of consciousness, psychomotor and cognitive recoveries from general anesthesia were observed. The VAS scores of pain were evaluated 48 h after operation.ResultsThe concentrations of end-tidal isoflurane in the controlled group were significantly higher than other groups (P<0.01). There was no difference among the three groups in the volume of bleeding, transfusion, infusion and urine. The recovery time of conscious, psychomotor and cognitive from general anesthesia were shorter in group Ⅱ and Ⅲ (P<0.01). The total dose of tramadol and VAS score after the operation were no difference among the three groups.ConclusionThe preoperative application of lornoxicam can reduce the concentrations of end-tidal isoflurane significantly, smooth the recovery from anesthesia.

Objective To observe the difference of gene expression profiles of lung in rats before and after endotoxic shock (ES). Methods A total of 20 male Wistar rats were randomly divided into control group and lipopolysaceharide (LPS) group ( 10 rats per group). The LPS rat model was made by injecting LPS into tail vein. Six hours after ES, partial pressure of oxygen in the arterial blood ( PaO2 )was measured. Gene expression profiles of the lung in each group were detected by rats oligo gene chip Affymetrix RAT 230A. The expression level of five genes was verified via semi-quantitative RT-PCR. The data were analyzed in combination with type of differential gene and character of ES. Results Compared with control group, PaO2 in LPS group was decreased more significantly (P ＜0.05). Among 15 650 probes detected, 158 genes showed differential expression in ES group in comparison with control group. The expression level of 117 genes was up-regulated while that of 34 genes down-regulated significantly. According to their biological function, differentially expressed genes were classified as inflammation genes, material transporter genes, transcription regulator genes, signal transduction genes, stress response genes, metabolic genes, apoptosis genes and cell adhesion genes. The results of Semi-quantitative RT-PCR of five genes were consistent with those of the microarray examination. Conclusion The expression of many genes of the lung may change in ES rats, especially the inflammatory genes.

BACKGROUND:The vascularization plays a key role in bone formation and reconstruction. Bioactiveβ-tricalcium phosphate has a porosity and absorbability that al ow a possibility of constructing vascularized bone.
OBJECTIVE:To explore the blood supply and construction of the central vascularizedβ-tricalcium phosphate, as wel as the mechanism of vascularization in artificial bone for its further clinical application.
METHODS:The lumbar dorsal artery of New Zealand rabbits was isolated and prepared into vascular bundle. At the experimental side, the vascular bundle was implanted into channel of theβ-tricalcium phosphate, then fil ed with the autologous tiny bone particles, and embedded into the latissimus dorsi muscle. Animals without the vascular bundle implantation were taken as the control group. The samples were determined for the morphology and histology at 4, 8, and 12 weeks post-surgery.
RESULTS AND CONCLUSION:The site where the vascular bundle was implanted appeared foramen nutriens-like structure, the blood vessels were abundant and smooth. The central vascularized tricalcium phosphate were fil ed with new-born vessels at 4-8 weeks. The newly formed bone and bone metabolism appeared at 4 weeks and newly formed bones were more mature at 12 weeks. In the control group, there were only a few new-born vessels, the newly formed bone was immature. The central vascularizedβ-tricalcium phosphate can significantly improve the vascularization of artificial bone. This model can probably serve as a new method for tricalcium phosphate in clinical use.

Objective To observe the therapeutic efficacy and safety of recombinant tissue plasminogen activator (rt-PA) for treatment of patients with acute cerebral infarction and investigate the prognostic factors of thrombolysis. Methods The clinical data of 60 patients with acute cerebral infarction from January 2009 to November 2013 in Department of Emergency, Hangzhou Traditional Chinese Medicine Hospital were retrospectively analyzed;of them, 30 cases received intravenous rt-PA thrombolytic treatment, being in the thrombolytic group, 0.9 mg/kg rt-PA was given to the patient within 4.5 hours after the disease onset, the total dosage could not exceed 90 mg, in which 10%was intravenously injected and the rest 90%was intravenously dripped slowly within 60 minutes. That another 30 cases did not undergo thrombolytic therapy was assigned as the control group, and they took aspirin, etc anti-platelet aggregation routine treatment. Before and after thrombolytic treatment for 1 hour, 24 hours and 14 days, the National Institutes of Health Stroke Scale (NIHSS) score was evaluated in the two groups;before and after thrombolytic therapy for 0.5, 1.0, and 1.5 hours, the patient's scores of Barthel index (BI) were observed in the two groups. In thrombolytic group, the situations of hemorrhage transformation, symptomatic hemorrhage and modified Rankin scale (mRS) score in 3 months of the patients with different ages, complications and NIHSS scores were observed. Results Before treatment, no statistically significant differences were found in the NIHSS score (15.2±3.6 vs. 15.5±3.3) and BI score (45.0±8.8 vs. 44.1±7.6) between the control group and thrombolytic group (both P>0.05);after treatment with the extension of time, the NIHSS score was gradually reduced, reaching the lowest level on the 14th day after thrombolytic treatment, while the BI score was gradually increased, reaching its peak at 1.5 hours after thrombolytic treatment, the changes being more prominent in thrombolytic group (NIHSS score:9.7±2.6 vs. 12.8±4.2, BI score:82.6±7.8 vs. 69.6±9.8, both P<0.05). In thrombolytic group, there were cerebral hemorrhage transformation 2 cases, gum bleeding 3 cases, skin bleeding 1 case, urethral bleeding 1 case, gastrointestinal bleeding and black stool 1 case. In control group, cerebral hemorrhage transformation was seen in 1 case. There was no obvious systemic hemorrhage in the two groups. In the 30 cases in thrombolytic group, the baseline NIHSS score of patients>80 years old was higher than that in cases≤80 years old (15 vs. 12); the age (years: 71.0±4.1 vs. 61.5±2.6), baseline NIHSS score (14 vs. 11) and bleeding conversion rate [37.50% (3/8) vs. 18.18% (4/22)] of cases with atrial fibrillation were higher than those not complicated with atrial fibrillation; the NIHSS score of cases with elevated international normalized ratio (INR) was lower than those without elevated INR (11 vs. 14);The bleeding conversion rate [16.67%(1/6) vs. 29.17%(7/24)] with NIHSS score≤4 were lower than those with NIHSS score>4;the mRS score in 3 months (4 vs. 2), and percentage of 3-month mRS score≤2 [11.1%(1/9) vs. 52.38%(11/21)] in cases with NIHSS score≥20 was higher than that in cases with NIHSS score<20 (all P<0.05). The fatality rate of two groups was 3.33%. Conclusions The intravenous rt-PA thrombolytic treatment can significantly promote the early recovery of neurologic impairment for patients with acute cerebral infarction. The therapy can improve the prognosis and its safety is relatively good. Meanwhile it is similarly effective for cases over 80, with complications such as atrial fibrillation, raised INR, and with different degrees of severity.

Objective To investigate the effect of hyperbaric oxygen( HBO) in craniotomy for traumatic brain injury. Methods The 90 patients with traumatic brain injury who received craniotomy in our hospital from March 2012 to September 2014 were divided into the obser-vation group(51 cases) which received HBO therapy additionally and the control group(39 cases). The remission rate of brain edema,GCS score,incidence of lung infection,infarction incidence and subdural effusion incidence at the same course of HBO treatment between the two groups were observed and compared. Rsults The remission rate of cerebral edema of observation group was higher than that of control group after a course of HBO treatment. And 6 days,9 days,12 days and 15 days after the course of HBO treatment,the GCS scores of observation group/control group were 8. 2/7. 8,9. 8/9. 0,11. 2/10. 3 and 12. 2/12. 0,respectively. The lung infection incidence of study group was lower than that of control group. Conclusion HBO treatment can improve the remission rate of brain edema and GCS scores, and it can reduce lung infection incidence in craniotomy for traumatic brain injury.

Objective To study the regulatory effect of cefodizime on the T-lymphocyte subsets of peripheral blood in mice with immunological liver injury.Methods The mouse model of immunological liver injury was induced by Bacillus Calmette Guerin and Lipoposaccharide.The study was conducted by using completely random design.The mice with immunological liver injury were divided into thymosin group,cefodizime high-,medium-,low-dose groups,ceftriaxone group and the normal saline group.The six groups were continuously administered agents respectively for 7 days,and T-lymphocyte subsets of peripheral blood in mice were determined and contrasted with those of the normal mice treated with normal saline on the 7th day.Flow cytomytry was used to determine the effects of cefodizime on T-lymphocyte subsets of peripheral blood in mice by using immuno-fluorescence technique.Results The immunological liver injury mice were deficient because their CD3+(%),CD4+(%),CD8+(%) and the ratio of CD4+CD8+ were lower than those of the normal mice.Cefodizime effectively increased CD3+(%),CD4+(%) and the ratio of CD4+CD8+ of the mice with immunological liver injury.Conclusion Cefodizime effectively improves the immune function of the host by regulating the balance between CD4+ cell and CD8+ cell.

[Objective]To explore the technique and results of reverse less invasive stabilization system(LISS) plating for subtrochanteric femur fractures.[Method]From October 2007 to May 2009,31 cases of fresh subtrochanteric femur fractures were treated with reverse LISS. There were 23 males and 8 females,with an average age of 48.6 years (range 27 to 83 years). Twelve injuries were the result of a traffic accident,six,a fall from a greater height,four,a crush injury and nine,a fall from a standing height. According to Seinsheimer classification,four fractures were type ⅡC,twelve ⅢA,six ⅢB,six Ⅳ and three Ⅴ. After anesthesia was effectively administered,subtrochanteric fracture was reduced indirectly with patient on a fracture table. Then,the reverse LISS plate was inserted through a lateral incision of the greater trochanter between the lateral vastus muscle and the periosteum. Guided by the aiming arm,4 to 5 screws were inserted through stab incisions into the proximal and distal fragments,respectively. [Result]Operative time averaged 50 minutes (range,35-80 minutes) and estimated blood loss averaged 90 ml(range,60-150 ml). Thirty-one patients were available for evaluation with an average follow-up of 15.6 months. All fractures healed at a mean of 18.2 weeks (range 13 to 32 weeks). There was no failed fixation,or deep infection. Average range of motion of the hip joint was recorded as follows:flexion 115?,external rotation 35?,internal rotation 15?,adduction 15?,and abduction 36?. According to the modified Harris hip score,scores ranged from 82 to 100 (average,92.6),and there were 24 excellent and 7 good results.[Conclusion]Reverse LISS plating yields good results in subtrochanteric femur fractures,with stable fixation and minimal invasive procedure.
