ObjectiveTo investigate the correlation between the level of resistin and the insulin resistance(IR) and the incorporation of microamount albuminuria(MA) of type 2 diabetes mellitus (T2DM).MethodsTwo hundred and twenty T2DM patients and 40 normal subjects (control group) were enrolled in this study.Two hundred and twenty T2DM patients were divided into 4 groups,IR group (group A,79 cases),non-IR group (group B,48 cases),IR complicating MA group (group C,51 cases),non-IR complicating MA group(group D,42 cases).The fasting serum resistin was measured by enzyme-linked immunosorbant assay (ELISA),and the fasting plasma glucose (FPG),glycosylated hemoglobin (HbA1c),fasting insulin (FINS) was also determined.ResultsThe level of fasting serum resistin in group A,B,C and D was higher than that in control group [(33.45 ± 1.37),(23.36 ± 1.47),(44.45 ± 1.39),(37.45 ±1.57) μ g/L vs.( 17.44 ± 1.26 ) μ g/L],and there was significant difference among 5 groups (P ＜ 0.01 ).The level of fasting serum resistin in group A was higher than that in group B (P ＜ 0.01 ),and the level of fasting serum resistin in group C was higher than that in group D (P ＜ 0.01 ).The level of fasting serum resistin was both higher in group C and D than that in goup A and B (P＜ 0.01 ).Correlation analysis showed the fasting serum resistin was positively correlated with body mass index(BMI),FPG,HbA1c and FINS in group A(r =0.35,0.46,0.37,0.49,P ＜0.05),and the fasting serum resistin was positively correlated with HbA1c,BMI,systolic blood pressure and diastolic blood pressure in group C(r =0.45,0.32,0.37,0.29,P ＜ 0.05 ).ConclusionsSerum resistin may participate in the process of IR and the formation of MA.It may become one of the diagnostic standard of the IR and one of the important index to estimate the MA.

Objective To explore the effects of wearing ankle-foot orthoses (AFOs) on motor function in children with spastic cerebral palsy (SCP). Methods Fifty-two children with SCP were randomly divided into a wearing-for-training group (n = 16, group 1 ), a day-wearing group (n = 19, group 2) and a day-night-wearing group (n = 17, group 3). In addition to the conventional rehabilitative treatment given to all participants, the children in group 1 wore AFOs during movement training, and children in group 2 wore AFOs in the daytime for 6-8 h per day, while AFOs were applied to the children in group 3 for 24 hours a day except for cleaning and during certain training routines. All the treatments were continued for 2 months. Clinical assessments included the range of passive ankle dorsi-and plantarflexion (APROM) , modified Ashworth scale (MAS) ratings, and the D and E dimensions of the Gross Motor Function Measure (GMFM). All were performed before and after treatment. Results Before treat-ment, no statistically significant differences were found among the three groups in terms of APROM, MAS, or GM-FM. There were significant subsequent improvements in groups 2 and 3 when compared with group 1 in terms of APROM, MAS and GMFM results. Group 2's improvements in APROM and MAS results were not significantly better than those of group 3, but their average GMFM score improvements were significantly better. Conclusion Wearing AFOs in the daytime 6-8 hours per day is more effective in reducing spasticity and improving functional performance in children with SCP.

Objective To study the characteristics of mesenchymal stem cells(MSCs)derived from chronic myelogenous leukemia(CML)patients' bone marrow and examine their hematopoiesis support in vitro.Methods MSCs from CML were obtained and cultured.Immunophenotype and in vitro differentiation capacities were investigated.Moreover,the Ph chromosome and bcr/abl gene of CML derived MSCs were detected.The expression of cytokines was detected by RT-PCR,and hema- topoiesis support of MSCs in vitro was detected by long-term bone marrow culture and the methylcel- lulose progenitor assay.Results CML derived MSCs showed a typical fibroblast like morphology. They were positive for CD29,CD44 and CD105,while negative for CD14,CD31,CD45,CD34 and HLA-DR.Under suitable conditions,CML derived MSCs could differentiate into osteoblasts and adi- pocytes.Further,CML derived MSCs showed a normal choromosome,and did not express bcr/abl gene.At last,they expressed hematopoiesis cytokines and possessed ability of hematopoiesis support in vitro.Conclusion There are MSCs with multidirectional differentiation potential in CML bone mar- row and they possess the ability of hematopoiesis support.

In this study, sonography video urodynamic studies (SVUDS), which combined synchronically urodynamic studies with trans-perineal and trans-abdominal sonography, were used to detect female bladder outlet obstruction (FBOO). The dynamic changes of urethra and surrounding pelvic floor structure during storage and voiding phase were observed by SVUDS and the causes of FBOO were analyzed. And the findings were as follows: 13 patients showed organ prolapse, there was an urethral angulation deformity during urination; 5 cases had abnormal urination as the urethral opening was not good in the middle of urination period; 4 cases had urethral stricture, as the proximal end of the obstruction dilated during urination, and the obstruction site showed no relaxation; 1 case had primary bladder neck obstruction with an incomplete opening of the bladder neck during urination; 3 cases had idiopathic bladder outlet obstruction and the sphincter of bladder neck and urethra opened well during urination.

Objective To explore the relationship between age and refractive predictability of excimer laser in situ keratomileusis (LASIK)for the correction of myopia.Design Retrospective case series.Participants 362 patients(703 eyes)who had performed LASIK.Methods According to the age,patients were divided into four groups(≤30y,31～34y,35～39y and≥40y).Their preoperative and postoperative refractive powers examined with automatic refactor as well as manifest optometry were analysed and followed up from 6 months to 2 years.According to pre-operative refractive power,patietns were divided into low and moderate myopia group(≤-6.00D), high myopia group(-6.25～-12.00D)and super-high myopia group(≥-12.25D).The eyes with refractive power at post-operative 2 years≥-1.00D were regressive eyes.Main Outcome Measures Refractive error before surgery,intended residual refractive power and 3,6, 12, 24 months post-operative refractive powers.Results There were no significant differences between intended residual refractive powers and refractive powers at post-operative 6 month in 3 groups(

BACKGROUND:It is difficult to perform superselective catheterization of the internal carotid artery in dogs because of the large bending and spiral shape of the interal carotid artery before entering into the skul. At present, the dog models of cerebral infarction established by injecting autologous blood clots and gelatin spongevia the internal carotid artery are far from the perspective of pathological mechanism of human patients with cerebral infarction. Aortography can visualize the structure of cerebral vessels and is likely to provide a new condition for the establishment of dog models of acute cerebral infarction. OBJECTIVE:To explore the feasibility of establishing cerebral infarction models in beagle dogs by superselective catheterizationvia the vertebral basilar artery. METHODS: Five beagle dogs were divided into thrombus group (n=3) and control group (n=2). The beagle dogs in the thrombus group were subjected to digital subtraction angiography of the aortic arch, bilateral common carotid arteries and vertebral arteries in addition to femoral arterial catheterization. The 2.7F micro-catheter was inserted into the convergence zone of the left posterior communicating artery and the internal carotid artery through the vertebrobasilar artery. An autologous blood clot was injected into the convergence zone. The dogs in the control group were injected with appropriate amount of contrast medium. RESULTS AND CONCLUSIONS:Through angiography of the left and right common carotid artery of five dogs, thick external carotid arteries (10/10) and their branches were clearly displayed, however, only five (5/10) internal carotid arteries were dimly present. A spiral vascular loop formed in the internal carotid artery with a smal-sized diameter. Through antiography of the left and right vertebral arteries (10/10) angiography, vertebral basilar artery, the circle of “Wilis”, bilateral posterior cerebral arteries, bilateral middle cerebral arteries and bilateral anterior cerebral arteries were clearly displayed, al these contribute to insertion of microcatheter into the convergence zone of the left posterior communicating artery and the internal carotid artery through the vertebrobasilar artery. High signal intensity of the left temporal lobe was shown on 3-hour and 6-hour diffusion weighted images.The results demonstrate that the beagle dog models of acute cerebral infarction can be successfuly established by injecting autologous blood clots into the left middle cerebral artery through a microcathter insertedvia the vertebrobasilar artery, which provides a new method of precisely occluding the middle cerebral artery of beagle dogs by catheterization.
