[Objective]To investigate the treating effect of bicondylar tibial plateau fractures with lateral supporting plate and compression screw system.[Method]Forty-six cases of bicondylar tibial plateau fractures were treated with internal fixation from the year of 2000 to 2004 in our hospital.All of them were treated with open reduction and internal fixation by lateral supporting plata and compression screw system.Orthopaedic evaluation at latest follow-up included a knee functional outcome and radiographic examination.[Result]Forty-six cases were followed up for 12 to 18 months(averaged,14.4 months).All fractures healed.According to Rasmussen scale,84.8% excellent and good results were obtained.[Conclusion]Most of all bicondylar tibial plateau fractures were stabilized by applying lateral supporting plate and compression screw system.This system help reduce complication rates resulting from open reduction and internal fixation.

Objective To observe the outcome of Nimodipine and Salvia Miltiorrhiza Composite in treating newborn hypoxic ischemic encephalopathy(HIE ) . Methods 128 HIE patients were randomly divided into four groups;-Salviae Miltiorrhiza Compsite treated group (n=32) , Nimodipine treated group (n 30) , Nimodipine plus Salviae Miltiorrhiza Composite treated group ( n =35) , and control group ( n =31) , in which the symptoms and signs , the reactions following treatment were observed .Results The total effective rates of Salviae Miltiorrhize Composite treated group , Nimodipine treated group , Nimodipine plus Salviae Miltiorrhiza Composite treated group were 81.3% (26/32) , 80% (24/30) and 97.1% (34/35) respectively , and the markedly effective rates were 53.1% (17/32) , 53.3% (16/30) and 88.6% (31/35) respectively . The total effective rates and the markedly effective rates of control group were 51.6% (16/31) and 6.5% (2/31) respectively ,the treated groups were higher than that of control group ( P

0 8*!cm) found by ultrasound. As a result tentative diagnosis of Mirizzi's syndrome was established in 54 cases accounting for 0 56% of all LC patients.Results Laparoscopic procedure was successful in 46 out of 50 type Ⅰ cases. Four cases suffering from iatrogenic bile duct injury received primary repairment under laparoscopy. Fistulae repairment was successful laparoscopically in 3 out of 4 cases of type Ⅱ Mirizzi syndrome.Conclusion Type Ⅰ and type Ⅱ Mirizzi syndromes can be safely and successfully managed under laparoscopy in the hand of careful and skilled operators.

AIM:To study the effect of fractalkine(CX3CL1,Fkn) on the expression and secretion of matrix metalloproteinase-2(MMP-2) in cultured human monocyte line U937 cells.METHODS:The cultured U937 cells were incubated with recombinant human Fkn,the supernatant of human renal mesangial cells(HRMC) and Fkn neutralizing antibodies for 24 h.The mRNA expression of MMP-2 was analyzed by RT-PCR.The production of MMP-2 in the supernatant was analyzed by gelatin zymography.RESULTS:The level of MMP-2 mRNA and protein in the cells incubated with recombinant human Fkn decreased compared to control group.Similarly,the level of MMP-2 mRNA in the cells incubated with the supernatant of HRMC reduced compared to control group.However,the level of MMP-2 mRNA and protein in the cells incubated with the supernatant of HRMC adding Fkn neutralizing antibodies increased compared to that incubated with the supernatant of HRMC.CONCLUSION:Fkn inhibits the expression and secretion of MMP-2 in cultured U937 cells.HRMC might mediate the expression and secretion of MMP-2 in U937 cells through Fkn.

Objective To investigate the mechanism of neural protection of mouse nerve growth factor combined with sub-hypothermia in the treatment of patients with severe traumatic brain injury. Methods 90 cases of severe traumatic brain injury were randomly divided into study group and control group with 45 cases of each group, the control group were given routine treatment; the study group were given on the basis of routine treatment of mouse nerve growth factor combined with sub-hypothermia treatment, with 2 weeks treatment, the clinical indicators and corresponding nerve injury, inflammation, oxidative stress indexes, clinical effect and complications were compared after 2 weeks treatment. Results Compared with before treatment or control group, scores of Glasgow coma scale (GCS) and Glasgow outcome scale (GOS) and montreal cognitive assessment (MoCA) in study group after the treatment increased, National Institute of Health stroke scale (NIHSS) score decreased(P<0.05), neuronspecific enolase (NSE), myelin basic protein (MBP) and S100 beta levels decreased(P<0.05), the serum tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6), IL-10 levels decreased (P<0.05), the malondialdehyde (MDA) decreased, the glutathione peroxidase (GPx) and oxidation resistance (AOA) levels increased (P<0.05). The control group efficiency was 73.33%, the study group efficiency was 91.11%, there was significant difference (P<0.05). All patients were followed up, no case off, there was no significant difference in adverse drug reaction rate between two groups. Conclusion Mouse nerve growth factor and sub-hypothermia has the significant neural protection for patients with severe traumatic brain injury, and its mechanism may be related to reduce nerve injury indicators and improve inflammatory factor and oxidative stress response.

ObjectiveTo investigate the characteristics of growth and secretion in primarily cultured human pheochromocytoma cells.MethodsThe human pheochromocytoma tissues were digested successively,and the tumor cells were cultured.The growth curves of three tumors were plotted by cell count.At the same time,the catecholomine in the medium was measured with high performance liquid chromatography.ResultsThe number of primarily cultured human pheochromocytoma cells increased gradually from first to sixth day after plating,and then the cell number began to decrease from seventh day.The levels of norepinephrine(NE) and epinephrine(E) in the medium of cultured cells significantly decreased on first and second day,and the levels of NE and E had no significant difference on the second to eighth day.The levels of dopamine in the medium had no significant difference on the first to eighth day.ConclusionThe primarily cultured pheochromocytoma cells differentiate obviously after plating,but have no significant proliferation.The levels of catecholomine in the medium are decreased significantly on the first and second day.

Objective To evaluate the effectiveness and safety of terazosin in the treatment of benign prostatic hyperplasia (BPH)patients with concomitant hypertension.Methods A singlecenter prospective clinical observational study was conducted from March,2006 to March,2010 in our center.The main endpoints were the changes of IPSS total score,diastolic and systolic blood pressures at the end of 4 weeks and 3 monthes compared with the baseline,The second endpoints were Qmax value at the end of 4 weeks and 3 monthes compared with the baseline,Safety was assessed by adverse events.Results There were 212 patients in the study recruited,and 189 patients completed the study.All patients had BPH combined with hepertension.All patients were randomly devided into two statistical analysis group,blood pressure well controled and not well controled group,In the well controlled group,the IPSS socre reduced from 22.31 ± 5.18 at baseline to 15.64 ±3.91 at the end of the 4th weeks and 13.16 ± 3.53 at the end of 3rd monthes in the blood pressure well controled group populatin( P ＜ 0.01 ).The Qmax were improved significantly from (7.87 ± 2.41 ) ％ at baseline to (14.19 ±2.64)％ at the end of the 4th weeks and (15.69 ±2.77)％ at the end of3rd monthes in the blood pressure well controled group populatin( P ＜ 0.01 ).Terazosin had moderate effect in blood pressure decreasing (P ＜ 0.05 ),and all patients were within normal blood pressure range.In the uncontrolled group,the IPSS socre reduced from 21.55 ± 4.82 at baseline to 15.44 ± 3.66 at the end of the 4th weeks and 12.96 ± 3.11 at the end of 3rd monthes in the blood pressure well controled group populatin (P ＜ 0.01 ).The Qmax were improved significantly from ( 8.27 ± 2.27 ) ％ at baseline to ( 14.26 ± 2.87) ％ at the end of the 4th weeks and ( 15.51 ±2.92) ％ at the end of 3rd monthes in the blood pressure well controled group populatin( P ＜ 0.01 ).Terazosin decreased BPH patient blood pressure with controlled patients and unctrolled patients additionaly to other blood pressure medicine (P ＜ 0.05 ),and no severe side effect occured.At the end of the study,all patients were taking drug continuously and were followed.Conclnsion Terazosin can significantly improve the symptoms and quality of life in BPH patients with hypertension with good safety and compliance.
