At the moment of its WTO accession, China also enters the stage of mass higher education. Mass higher education is an objective inevitability of the economic and social development. China's mass higher education lays a firm foundation for China to join the WTO and the WTO entry in turn brings considerable opportunities to it. It is expected that the WTO entry will promote the process of mass higher education of China.

Objective To investigate the correlation of serum advanced glycation end products (AGEs) and the expression of receptor for AGE (RAGE) with mental disorders in senile people. Methods All the subjects aged 65～67 years were divided into 4 groups: healthy control (31 cases), Alzheimer's disease (AD) (36 eases), vascular dementia (VD) (20 cases) and mental disorder (MD) (28 cases). Fluorospectrophotometry was carried out to measure the AGEs levels in serum samples, and reverse transcription polymerase chain reaction (RT-PCR) was used to determine the mRNA levels of RAGE in white blood cells. Results AGEs levels were 477. 1±36.2, 512. 6±33.2 and 415.2±32.5 AU/ml in AD, VD and MD group, respectively, which were higher than that in healthy control group (357.4±28. 2) AU/ml (F=3.77,P<0. 05). The mRNA levels of RAGE(RAGE/b- actin) were found to be 1.12±0.34, 1.27±0.41 and 1.18±0.42 in AD, VD and MD group, respectively, which were also significantly higher than that in healthy control group(0. 92±0. 37, F= 4. 07,P<0. 01). However, no significant differences were found in RAGE mRNA levels among the three groups of AD,VD and MD (F=0. 979,P>0. 05). The mRNA levels of RAGE in WBCs were found to be positively correlated with the serum AGEs levels (r=0. 442, P<0. 01). Conclusions Compared with patients in healthy control group, the serum AGEs levels and RAGE mRNA levels are significantly increased in patients with AD, VD and MD. The interaction between AGEs and RAGE may be involved in the pathogenesis of mental disorders in senile people.

Objective:To investigate the expression of Toll-like receptors(TLRs)signaling pathway in chronic rhinosinusitis(CRS)with nasal polyps.Method:Gene microarray analysis was used to detect the expression of TLRs signaling pathway in CRS with nasal polyps.Result:Of 19 differentially expressed(two-fold changes),4genes were upregulated and 15 genes were downregulated.Conclusion:The differentially expressed genes in TLRs signaling pathway may exert its effect in the pathogenesis of CRS.In addition,the roles of TLR9 and its agonists need further study.

Cerebrovascular reserve is an important parameter for evaluating cerebrovascular disease,and it has great clinical significance.There are a number of determination methods for cerebrovascular reserve,such as position emission tomography(PET),single photon emission computed tomography(SPECT),Xenon-133 inhalation technique,Xenon CT,perfusion CT, magnetic resonance imaging(MRI),transcranial Doppler(TCD),transcranial harmonic perfusion imaging(HPI),near infrared spectroscopy(NIR),and Laser Doppler vibrometry(LDV), however,there have been no unified criteria up to now.The provocation test that makes cerebral blood flow increase includes CO_2 inhalation test,breath holding test,and acetazolamide test,etc. The article focuses the discussion on the advantages and disadvantages of the above determination methods.

Objective: To establish a determination of bacterial endotoxin in Xiangdan Injection by kinetic-turbidimetric technique. Methods: The sample diluted times without interference was found out by adding bacterial endotoxin into sample and determining recovery ratio. Results: When the sample was diluted 40-times, the interference of sample to limulus test was eliminated efficiently. Conclusion: The method can be applied to determine the bacterial endotoxin quantitatively in Xiangdan Injection.

[Objective]To evaluate the efficacy of nerve transfer for reconstructing the sensory function of the sole.[Method](1)Select saphenous nerve as donor nerve for the patients with the sensory loss beneath ankle level:dissect and cut off the saphenous nerve at the medialposterior aspect at upper-middle 1/3 of the leg and divide the gastrocnemius to expose the tibial nerve at the medialposterior aspect of the tibia, cut off partly nerve fibre of the tibial nerve and then end-to-end anastomose to the proximal end of the saphenous nerve. (2) Select sural nerve as donor nerve for the patients with sensory loss of sole only:dissect and cut off the sural nerve at the posterior aspect of the lateral malleolus, expose the tibial nerve at the posterior aspect of the medial malleolus and then cut off partly nerve fibre of the tibial nerve. The sural nerve was comdicted from the subcutaneous tunel at the anterior aspect of the Achilles's tendon to the posterior aspect of the medial malleolus and end-to-end anastomose to the partial nerve fibre of the tibial nerve. [Result]All the 9 cases were followed up from 1.5 to 2 years(mean 2 l months). The SCV(sensory conduction velocity) of the tibial nerve was ranged from 36.1 to 41.2 m/s, mean 38.3 m/s and the amplitude of wave (peak-to-peak amplitude) was a range from 7 to 15.3?V, mean 11.2 ?V by orthodromic electrophysiologic techniques. All 9 cases regained the sense of pain and touch of the sole.Three cases restored their sense of two point discrimination. All the patients expressed their satisfaction with their ability of walk and no muscles atrophy of the foot. The sensory loss in donor region was oberserved only lateral part of the foot beneath the lateral malleolus (sural nerve as donor nerve) and a small part of the anterior aspect of the ankle(saphenous nerve as donor nerve).[Conclusion]Nerve transfer can reconstruct the sensory function of the sole effectively.

[Objective]To evaluate the clinical outcome of the Ribbed anatomic cementless prosthesis.[Method]A total of 1436 hips in 956 patients undergone THR with Ribbed anatomic cementless prosthesis were reviewed.Between March 1997 and September 2005,1 249 hips in 832 patients were available for clinical and radiological follow-up.The mean follow-up period was 6.7 years with a minimum of 2 and a maximum of 10.5 years.The patients were evaluated with Harris Hip Score and radiographic analysis.[Result]The mean Harris Hip Score increased from 34.7 preoperatively to 91.5 postoperatively.Excellent and good functional improvement was seen in 96.3% of the operated patients.There was neither periprosthetic osteolysis nor evidence of loosening on follow-up radiographs.[Conclusion]Ribbed anatomic cementless prosthesis is found to be performing well with good clinical and radiological result.
