Objective To investigate the critical thinking ability of medical students and its related factors in order to provide evidence for higher medical education reform. Methods A total of 325 medical students were selected by cluster sampling method, and Critical Thinking Disposition Inventory-Chinese Version (CTDI-CV) was adopted for survery. Results The average total score of critical thinking ability of medical students was above 280, and 51.08% of students showed positive critical thinking ability. Among all the seven critical thinking dispositions, average scores of each item were all positive (>40) except that the significance of truth seeking (37.23) and systematicity (39.05) were indefinite. There were significant differences in critical thinking ability between medical students with different gender and academic years (P<0.05). Conclusion The critical thinking ability of medical students is positive, however, there still exist some shortages. An equal relationship between teachers and students should be established, the traditional course system be continuously reformed, a good environment for clinical training be created, and a variety of teaching methods be implemented to further strengthen the critical thinking ability of medical students.

OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy and repair of the injured posteromedial complex structure of the knee joint in the treatment of posterolateral knee dislocation with multiple ligament injuries.
METHODSFrom March 2008 to August 2012,22 patients (16 males and 6 females, ranging in age from 20 to 53 years old, with an average of 30.5 years old) with posterolateral dislocation of the knee were treated with primary reconstruction of ACL and PCL, combined with the repair of injuries in the posteromedial complex and soft-tissue. Eight patients had injuries caused by sports,5 patients road accidents and 9 patients falling down. The ACL was reconstructed using the gracilis and semitendinosus tendons. The PCL was reconstructed using LARS artificial ligaments (14 cases), or gracilis and semitendinosus tendons (8 cases). Suture repair was performed in 17 patients with posteromedial ligament injuries,and self-semitendinosus strengthening operations were performed in 5 patients. Continuouspassive montion (CPM) and active exercises were executed after operation at early stage. The IKDC and Lysholm system were used to evaluate therapeutic effects.
RESULTSAll the patients were regularly followed up, and the duration ranged from 11 to 56 months (averaged, 39 months). According to the IKDC scale,9 patients got a grade A result, 10 got a grade B result, and 3 got a grade C result. The IKDC subject score was 89.6±3.1 and the Lysholm scores was 90.7±1.8 at the latest follow-up, which were both better than those before operation.
CONCLUSIONReconstructing the ACL and PCL and repairing injured posteromedial complex of the knee followed by an active rehabilitation is an effective method to treat posterolateral knee dislocation.

Objective To investigate the role of acid-sensing ion channels (ASICs) in global cerebral ischemia-reperfusion (I/R) injury in rats. Methods Forty-eight adult male Sprague-Dawley rats weighing 250-310 g were randomly divided into 4 groups ( n = 12 each): sham operation group (group S); global cerebral I/R group (group I/R); normal saline group (group NS) and specific ASIC blocker amiloride group (group A). Global cerebral I/R was produced by occlusion of 3 vessels ( 10 min occlusion of the bilateral common carotid arteries and basilar artery) followed by reperfusion. In group NS and A, NS 6 ml/kg and amiloride 0.6 mg/kg were injected through femoral vein immediately before reperfusion respectively. Six rats in each group were selected, the dialysate in CA1 area was collected before ischemia (baseline), immediately after ischemia and during 20 min reperfusion (once every 10 min) for determination of lactate concentrations. The left 6 rats in each group were elected at 8 h of reperfusion and the open field test and inclined plane test were peeformed to assess neurological behavior.The rats were then sacrificed and brain tissues taken for microscopic examination and brain water content was calculated. Results Compared with group S, the concentration of lactate in the dialysate and brain water content were significantly increased and neurological deficits developed in group I/R and NS (P < 0.05). Compared with group I/R, the concentration of lactate in the dialysate and brain water content were significantly decreased and neurological deficits were improved in group A ( P < 0.05 ), but no significant change in the parameters mentioned above was found in group NS ( P > 0.05). Microscopic examination showed that the damage to the brain tissues was attenuated in group A compared with group I/R. Conclusion ASICs are involved in the development of global cerebral I/R injury in rats.

OBJECTIVE:To study the effect and mechanism of tandospirone citrate (TC) on blood pressure in spontaneously hypertensive rats (SHR). METHODS:SHR were divided into model group,positive control group (Levamlodipine besylate tab-lets,2.5 mg/kg),TC high-dose,medium-dose,low-dose groups(TC capsules,40,20,10 mg/kg),8 in each group. Other 8 nor-mal rats were chosen as normal control group. The rats were intragastrically administrated medicines,once a day,for 28 d. Systolic blood pressure(SBP)before first administration and after 0.5,1,1.5,2,3,4 h of administration in each group were measured, and SBP after 1 h of administration were measured once every 7 d. After last administration,nitric oxide(NO)content in serum, endothelin,renin,angiotensin Ⅱ(Ang Ⅱ) and norepinephrine (NE) contents in plasma were detected. RESULTS:In single ad-ministration,compared with model group,SBP in 0.5,1 h in positive control group and TC groups after first administration were obviously decreased (P<0.05 or P<0.01),then SBP were obviously decreased only in positive control group and TC high-dose group (P<0.05 or P<0.01). In multiple administration,compared with model group,SBP in 7th,14th,28th day of administra-tion in positive control group and TC high-dose,medium-dose groups were obviously decreased(P<0.05 or P<0.01). Compared with model group,NO content in serum in positive control group,TC high-dose group were obviously increased;endothelin,re-nin,Ang Ⅱ and NE contents in plasma were obviously decreased (P<0.05 or P<0.01). Compared with positive control group, NO content in serum in TC groups was obviously decreased;endothelin,renin,Ang Ⅱ and NE contents in plasma were obviously increased in TC medium-dose group (P<0.05). CONCLUSIONS:TC can obviously decrease the blood pressure of SHR. The mechanism may be associated with adjusting the balance of NO and endothelin,and decreasing renin,AngⅡand NE contents.
