[Objective]To explore displacement and plantar pressure distribution of the forefoot before and after the plantar fascia and other plantar ligaments were sectioned.[Method]Seven fresh adult cadaveric feet were tested with the main plantar ligaments exposed,including the plantar fascia,spring ligament,short plantar ligament and long plantar ligament.The displacements of the metatarsals were recorded and calculated with digital speckle correlation measurement(DSCM),also F-scan insoles were put under the plantar aspect of the feet when the speciments were loaded to 700N vertically.The special shifts and plantar pressure data of the metatarsals was collected and stored before and after the main plantar ligaments were sectioned.[Result]The transverse movements of the metatarsals did not change significantly,the same as their vertical displacements except the first metatarsal after the plantar fascia was sectioned,while the peak pressure shifted laterally.When the four major plantar ligaments were all injured,all of the above changed significantly.[Conclusion]The plantar fasciotomy will not consequentially lead to collapse of the forefoot structure.But the redistribution of the plantar pressure and the compensation of other ligaments may result in later complication.

In order to evaluate the pathogenisis, definite the position and mechanism of ovarian dysfunction. Methods Pi-tuitarygonadal hormones ,-.P and prolactin (PRL) were measured in 25 premenopausal hemodialysis women using enzyme im-munoassay (E3A). Results Patients' serum PRL levels significantly elevated, FSFKLH levels also elevated, whereas P levels were obviously lower compared with normal women. Conclusion (1) Hypothalamic-pituitary-ovarian axis was impaired in uremia women as indicated by the prevalence of acydicity and the failure of LH,E2 levels and marked low P levels. (2)In uremia women clomiphenum stimulation test was positive suggested that the pituitary-ovarian axis were normal, whereas hypothalamic was impaired. (3) Hyperprolactinemia, owing to increased pituitary prolactin secretion. Suppression with bromocriptine was unstable. (4) During dialysis, symptom treating is suitable rather than trigger the ovalation. Successful renal transplantation is the best treatment.

Objective To explore the clinical users′experience on using the intelligent laboratory test system so as to provide reference for its optimization.Methods Fifteen laboratory staff with different sub specialty was selected for in-depth interviews and data were analyzed using phenomenological approach.Results Intelligent laboratory system could improve the quality of test result verification and interpretation,shorten the turnaround time and improve the work efficiency.It took about 1-2 months for users to accept the automatic verification function.After that,the users could believe in the system and used it in their daily work.The sys-tem could reduce the work stress and verification duty,while balancing the technical gap between laboratory technicians.Users could only understand the general rule of the intelligent system and it was difficult for them to manage the rule repository.Conclu-sion The intelligent laboratory system is one of the artificial intelligent system used for the medical laboratory,it can provide com-prehensive clinical decision support for the laboratory staff.

Objective To explore the role of long-term enriched environment in promoting the recovery of motor and social function in mice after ischemic brain injury. Methods Sixteen adult male ICR mice underwent permanent middle cerebral artery occlusion (MCAO). The first day after operation, they were divided into enriched environment group (n=8) and standard condition group (n=8). The mice were tested with modified Neurological Severity Score (mNSS), rotarod test and smart cage 7, 14, 21, 28 days after modeling. Results The score of mNSS and the result of rotarod test improved more in the enriched environment group than in the standard condition group 28 days after MCAO (t>2.927, P<0.05). The occupancy time in the middle of smart cage was longer in the enriched environment group than in the stan-dard condition group 7 to 28 days after MCAO (t>2.480, P<0.05) in the general move test. There was a trend of being more interested in strange mice in the enriched environment group than in the standard condition group, but the difference was not statistically significant (P>0.05) in the social behavior test; however, the occupancy time in the middle of smart cage was longer in the enriched environment group than in the standard condition group 14 to 28 days after MCAO (t>3.472, P<0.01), and the velocity of moving was higher 14 days after MCAO (P<0.05). Conclusion Enriched environment could promote the recovery of motor function, somehow of social function, in mice af-ter ischemic brain injury.

Objective To investigate the stimulate angiogenesis effect of bone marrow stem cell mobilization on coronary collateral development in the hearts of experimental myocardial infarction rats.Methods Left anterior descending coronary arteries were ligated to produce acute myocardial infarction(AMI)model in Wistar rats.Bone marrow stem cells were mobilized and home to the site of myocardial infarction by ginsenoside Rgl and Simvastatin.Hearts were harvested in the 24th hour,1st and 4th week after AMI modeling for histopathological examination.Immu nohistochemisty were used to detect infiltration of CD+34 cells and the expression of VⅢ factor in the part of ischemia.And infarct area were measured.Results Infarct area in mobilized group was obviously less than in AMI group.There were a great number of monocytes infiltrating with CD34 expression by immunohistochemisty in myocardial infracted zone in mobilized rats.Capillary density in mobilized group was greater than those of AMI and sham-operated groups.Conclusion In the AMI model of rat,bone marrow stem cells can be mobilized by ginsenoside Rgl and Simvastatin.The capillary density can be increased by mobilizing bone marrow stem cells.Ginsenoside Rgl and Simvastatin can improve the acute ischemic cardiac function by enhancing angiogenesis.

Background Increase of lens thickness at incipient cataract is a key factor of onset of primary angle-closure glaucoma (PACG).Phacoemulsification (Phaco) or phacotrabeculectomy (Phacotrabe) have been documented to be effective for the patients of PACG associated with cataract.However,which surgery is more effective and safe is lack of evidence.Objective This study was to assess and compare the clinical effectiveness of Phaco versus Phacotrabe for PACG with cataract.Methods The relevant literature was searched electronically from the PubMed (1966 to June 2011),EMB Reviews (1966 to June 2011) and Cochrane Library (Issue 1,2011).The manually searching of relevant conference proceedings was used as the supplement.The articles of randomized controlled trial (RCT) about the clinical effectiveness of Phaco versus Phacotrabe for PACG with cataract were included.The methodology quality of included literature was graded.The analysis indexes included intraocular pressure (IOP)-lowing range,postoperative administration of glaucoma drugs,incidence of positive complication,postoperative best corrective visual acuity (BCVA) and perimetry damage.The RevMan4.2 software from Cochrane Collaboration was used for the Meta analyses.Results Three RCTs about phaco versus Phacotrabe for PACG with cataract were selected in this study with the 164 eyes of 164 cases.Meta analysis showed that the IOP-lowing range was larger in the Phacotrabe group compared to only Phaco group with the WMD of 1.17 and 95％ CI of 0.06-2.27 (P =0.040),and the drug dosage of anti-glaucoma was less in the Phacotrabe group in comparison with the Phaco group with the WMD of 0.5 and 95％ CI of 0.24-0.77 (P =0.000).However,the incidence of postoperative complication was higher in the Phacotrabe group than that of the Phaco group with the RR of 0.08 and 95％ CI of 0.02-0.33 (P =0.000).No significant difference was found in the BCVA (WMD =0,95％ CI:-0.13-0.13,P=1.00) andperimetry (WMD =1.01,95％CI:0.56-1.82,P=0.98).Conclusions Compared with Phaco,Phacotrab has a better IOP-lowing effectiveness and slightly worse safety.Phaco and Phacotrab have a fairly influencc in the postoperative BCVA and perimetry.As the sample sizes of the included trials are relatively small,more welldesigned large-scale RCTs are needed.

ObjectiveTo compare the clinical value of contrast-enhanced ultrasonography (CEUS) and conventional ultrasonography in diagnosing polypoid lesion of gallbladder (PLG).MethodsThe postoperative pathology and clinical manifestation of 49 PLG patients were retrospectively analyzed in the First Afifliated Hospital of Harbin Medical University. Of them, 7 cases were maligant lesions, 4 cases were adenomas, 24 cases were polyps of gallbladder and 14 cases were adenomyomatosis of gallbladder. With postoperative pathology as golden standard, the sensitivity, speciifcity and PLG speciifcity were calculatedfor conventional ultrasonography, CEUS and conventional ultrasonography plus CEUS.ResultsThe sensitivity, specificity and PLG specificity were 33.3%, 74.3% and 68.3% for conventional ultrasonography, and 66.7%, 85.7% and 82.9% for CEUS respectively. The conventional ultrasonography plus CEUS were 83.3%, 88.6% and 87.8%.ConclusionCEUS could signiifcantly improve the diagnostic accuracy.

We reported a simple and fast fluorescence system based on quantum dots ( QDs ) to detect glutamate dehydrogenase ( GLDH) , which inverted glutamate to α-ketogrutarate using NAD+ as a coenzyme. The fluorescence of CdTe QDs was quenched by nicotinamide adenine dimucleotide ( NAD+) through an electron transfer pathway, and the quencher NAD+ could be consumed by adding NAD+-dependent enzymes and corresponding substrates. Based on this principle we introduced GLDH to consume NAD+ in the QDs/NAD+ system, leading to the enhancement of the fluorescence intensity of QDs, which was in proportional to the amounts of GLDH added. Using this fluorescence system, we measured GLDH in a wide concentration range from 10 U/L to 1000 U/L, which was of significance in clinical diagnosis of different kinds of liver diseases.
