ObjectiveTo review the treatment of 132 patients with vascular injuries admitted to our hospital from Jun,1985 to May,2001.Methods Clinical data were analyzed according to the cause, site, type, and surgical modality of vascular injuries. ResultsThe mortality rate in this group was 6.8%, amputation rate 8.3%, and patency rate of primary surgical treatment was 91.9%.ConclusionsSurgical exploration is the mainstay of diagnostic approaches for acute vascular injury; flexible measures should be taken to ensure high patent rate of the injuried blood vessel,lower mortality and high salvage of limbs.

Nutritional supplies & biodiversities of deep-sea microorganisms and correlative methodologies were introduced here in an ecological point of view, and development of their natural products was prospective in an applied point of view.

Objective To evaluate catheter-directed thrombolysis through popliteal vein for the treatment of lower extremity deep venous thrombosis (DVT). Method A total of 62 patients with single symptomatic lower limb DVT were analyzed. The popliteal vein of symptomatic limb was punctured, under Doppler guidance a 5-F sheath was advanced into the deep vein. A catheter was advanced beyond the thrombus. After a bolus of 200 000 IU urokinase, 100 000 IU/h urokinase was infused for up to three days, meanwhile 400 IU heparin was administered subcutaneously every 12h. Clinical efficacy grade was evaluated by measuring the perimeter of legs and lysis grade was calculated based on venographic results. Results In addition to total or partial removal of the thrombus collateral circulation increased, the limbs edema reduction rate was 78% and the thrombolysis rate was 67%. Thrombolysis rate in acute, and relapsing cases was significantly higher than in chronic group (75%,and 71% vs. 49%,P

Objective:To observe the influence of radiofrequency catheter ablation of the fat pad at the right pulmonary vein- atria junction(RPV fat pad)on Bezold-Jarisch reflex(BJR)induced by veratridine in canine.Methods:Ten mongrel dogs were anesthetized and their chest were opened through a right thoracotomy to expose the RPV fat pad.Veratridine was injected into the left ventricle at bolus doses of 10?g/kg through a catheter to induce BJR.The sinus cycle length(SCL),systolic arterial pressure(SAP),diastolic arterial pressure(DAP),mean arterial pressure(MAP),left ventricle systolic pressure(LVSP), left ventricle diastolic pressure(LVDP)and mean left ventricle pressure(MLVP)were measured under the baseline and after ablation of the RPV fat pad;the changes of the above parameters(?SCL,?SAP,?DAP,?MAP,?LVSP,?LVDP,and?MLVP)were calculated.Then the same dose of veratridine was injected under the pad after ablation and the changes of the a- bove parameters were observed.Results:BJR was successfully induced in the 8 animals;the animals has prolonged sinus cycle length(SCL)and decreased MAP and MLVP.After ablation,the prolongation of SCL after injection of veratridine was markedly reduced([229.2?92.3]ms vs[39.3?14.1]ms,P

OBJECTIVETo summarize the clinical experience in diagnosis and treatment of knee disease by arthrowand technique under arthroscope.

METHODSeventy-two patients were divided randomly into control and test groups (each 36 patients). The patients suffered from meniscectomy, synovitis and arthritis. The control group confirmed and treated by knee arthroscope, was subjected to debridement, cleansing and hole drilling for reduction of pressure. The test group was treated by arthrowand under arthroscope. All patients received rehabilitation therapy.

RESULTSThe patients developed no infection or complication. Better therapeutic results were obtained after follow up of 6 to 24 months.

CONCLUSIONArthrowand technique under arthroscope for the diagnosis and treatment of knee diseases has the advantages of less injury, bleeding, and complication but quick recovery.

OBJECTIVETo evaluate the biomechanical properties of tibial plateau depressed fracture fixed with a net-fixation of Kirschner wires.

METHODSTwenty homemade fracture models were fixed with eight 1.5 mm Kirschner wires in a net-fixation; 20 homemade fracture models were fixed with two 3.5 mm cortical screws. Plane-compressed and dot-compressed test were made on each 10 models of the two groups. The maximal force of anti-ompress and stiffness were measured and evaluated.

RESULTSIn plane-compressed test,mean maximal force of anti-compress and stiffness for screw fixation was (1,925.31 +/- 444.26) N and (2.28 +/- 0.53) N/mm2, respectively, for net-fixation was (1,609.62 +/- 277.72) N and (1.90 +/- 0.33) N/mm2, respectively. There was no statistical difference between the two fixation methods (P > 0.05). In dot-compressed test,mean maximal force of anti-compress and stiffness for screw fixation was (411.13 +/- 233.88) N and (2.66 +/- 1.52) N/mm2,respectively,for net-fixation was (1,105.58 +/- 290.66) N and (7.18 +/- 1.89) N/mm2,respectively,the net-fixation was better than that of the screw fixation (P< 0.01).

CONCLUSIONTreatment of tibial plateau depressed fracture with a net-fixation of Kirschner wires is a biological fixation and is a reliably method.

The efficacy of ~(131)I treatment of hyperthyroidism in children and adolescents was evaluated. Being unsuitable for medical therapy,31 patients (aged 11-18 years) with hyperthyroidism received ~(131)I treatment with a dose of 0.925-3.33 MBq/g of thyroid and were followed-up for 20 to 76 months.Fifteen patients were euthyroid,5 suffered from late-onset hypothyroidism,and 11 were still hyperthyroid,but their symptoms and signs of hyperthyroidism were markedly improved.Of the 18 patients with thyroid-associated ophthalmopathy (TAO),8 patients recovered,4 were improved,TAO in 1 patients deteriorated and in S patients remained unchanged.~(131)I is a relative safe and effective treatment for children and adolescents above 10 years old with hyperthyroidism,being unsuitable for medical therapy.

OBJECTIVETo investigate the effect and mechanism of prepared Radix Polygoni Multiflori (RPM) on the elevation of extracellular hydroxyl radical in striatum of rats induced by intracerebral perfusion of 6-hydroxy dopamine (6-OHDA).

METHODSCerebral microdialysis was used to establish the model. Hydroxyl radical was captured by salicylic acid, and 2,3-dihydroxy benzyl acid (2,3-DHBA) and 2,5-dihydroxy benzyl acid (2,5-DHBA) formed by hydroxyl radical in vital brain were measured by high performance liquid chromatography-electrochemical detector (HPLC-ED).

RESULTSAfter perfusion of 6-OHDA in brain of rats, the levels of 2,3-DHBA and 2,5-DHBA in the model group increased rapidly. The former was higher during the whole course of observation (P<0.01), while the latter was higher at most time points than that in the control group (P<0.05 or P<0.01). The level of 2,3-DHBA in the RPM group was lower than that in the model group at 5 time points (P < 0.05, P < 0. 01).

CONCLUSIONRPM could inhibit the elevating of extracellular hydroxyl radical in striatum of rats induced by intracerebral perfusion of 6-OHDA, indicating one of the brain protective mechanisms of RPM may be related to its anti-oxidation effect.

OBJECTIVETo observe the effects of Yinian Jiangya (YNJY) Decoction contained serum on cell proliferation of primary cultured endothelial cells of spontaneously hypertensive rat (SHR) and the peroxisome proliferator-activated receptor-gamma (PPAR-gamma) mRNA expression in the cells.

METHODSSD rats were fed with high-lipid diet and different doses (high, medium and low, containing crude drug of 5.2 g/mL, 2.6 g/mL, 1.3 g/mL respectively) of YNJY respectively and the serum contained different doses of YNJY (S-YNJY) was prepared by collecting the rats' serum after 20 days of feeding. The serum obtained from SD rats fed with normal diet, i.e. drug free serum (S-free) was taken for control. Primary cultured endothelial cells of SHR were treated respectively with S-YNJY in different doses (treated groups) and S-free (control group), the cell activity and the mRNA expression of PPAR-gamma in cells of all groups were detected by MTT and RT-PCR respectively at different time points: 2, 4, 8, 16 and 24 h after treatment.

RESULTSMTT test showed that at time points of 4 and 8 h, the OD value raised in the treated groups with insignificant difference among them (P>0.05), but was higher than that in the control group (P<0.05); at 16 h, it increased but showed a smaller increment in the medium-dose treated group (P<0.05); at 24 h, it decreased in all groups, but the decrement in the high- and medium-dose treated groups was more remarkable (P<0.05); at 48 h, it decreased continuously, with the decrement more significant in the high-dose group than in the control group (P<0.05). RT-PCR detection showed that at 4 h, the expression of PPAR-gamma mRNA was not changed significantly in all groups (P>0.05); at 8 h, it was remarkably lower in high-dose group than in others (P<0.05); at 16 h, it was higher in the three treated groups than in the control group (P<0.05), with a highest level shown in the high-dose treated group (P<0.01); at 24 h, the expression decreased in all groups, but the level in the low-dose treated group was still higher than that in the control group (P<0.05).

CONCLUSIONSYNJY Decoction shows a two-way regulation on endothelial cells proliferation, and which is negatively dose-dependent in the late stage. The regulation is perhaps relevant to the regulating of the PPAR-gamma mRNA expressions. The PPAR-gamma mRNA expression up-regulating and maintaining effects of YNJY Decoction may be one of the mechanisms for its vascular endothelial cell protection and blood pressure suppressing.
