2.Association of microalbuminuria with the risk factors of stroke and recurrence in patients with cerebral infarction
Chinese Journal of Tissue Engineering Research 2005;9(13):224-225
BACKGROUND: International research discovers that the risk factors of stroke have certain correlation with microalbuminuria(MAU) but the results are inconsistent.OBJECTIVE: To investigate the relationship between the incidence of MAU in patients with acute cerebral infarction and the risk factor of stroke and the recurrence of cerebral infarction.DESIGN: A case-control study based on patients with acute cerebral infarction and individuals with risk factors of cerebral infarction, and the healthy elderly as controls.SETTING: Inpatient department of neurology in a university hospital.PARTICIPANTS: Totally 214 cases with cerebral infarction or risk factors of cerebral infarction aged between 50 and 80 years old were selected from the Department of Neurology of the First Affiliated Hospital of Chongqing Medical University between January 2000 and December 2001. Acute cerebral infarction group (infarction group, attack within one week, n =78), cerebral infarction risk factor group(risk group, n = 56), such as, hypertension, diabetes,coronary heart disease (CHD), transient ischemic attack(TIA) or stroke history(more than 6 months), and healthy elderly(control group, n=28) .Thereinto, combined group( n = 109) included 78 cases of acute cerebral infarction and 31 cases with TIA or stroke history of risk factors.METHODS: Seralbumin, serum creatine(SCr), blood sugar, total cholesterol, total triacylglycerol(TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol(LDL-C) were detected after more than 12 hours of fasting. The albumin in the first urine in the morning was detected by radio-immunity analysis.the incidence of neo-vascular affair in 2 years of follow-up including recurtute indicator: incidence of MAU in each group.RESULTS: Patients with MAU accounted for 35% of acute cerebral infarction, which were significantly higher than that of risk group(15% ) and control group(3.5%, P < 0.01). Six independent risk factors predicting MAU existed in infarction group and combined group, which were diabetes, seralbumin level, age, CHD, hypertension, and HDL-C( P < 0. 05, or P < 0.01).After(1.5 ±0. 9) years of follow-up, 23% of patients of infarction group suffered from recurrent vascular accident, which was significantly higher than that of risk group(12% ) and control group(0%, P < 0.01 ). 36% of MAU patients in infarction group suffered from recurrent vascular accident, which was significantly different from that of patients with a great deal of albuminuria(41% ) and normal albuminuria(10%, P < 0. 05). MAU is the independent predicting indicator for the recurrence of stroke after the control of diabetes and hypertension in patients of infarction group and risk group with the risk rate of 3.8 (95% CI, 1.2-13.5; P <0.05) or 4. 7(95%CI,1.4-16.7, P < 0.01).CONCLUSION: MAU is quite common in acute cerebral infarction patients. After the adjustment of basic risk factors, MAU is the independent risk factor of the recurrence of cerebral infarction.

Academic Journal of Second Military Medical University 2010;27(12):1355-1357
Objective: To study the preparation technique for magnetic poly D, L-lactide-co-glycolide phenylarsine oxide nanoparticles (M-PLGA-PAO-NPs) and to characterize the resultant product. Methods: M-PLGA-PAO-NPs were prepared by using emulsion-evaporation process. The morphology of the prepared nanoparticles were observed by transmission electron microscope and the magnetism of the particles was determined by vibrating sample magnetometer. Meanwhile, we also evaluated the mean diameter, encapsulation ratio, and drug loading rate of the particles. Results: The nanoparticles had a regular spherical surface, with 80% of them having a diameter of 140-500 nm. We also found that the drug loading rate of the particles was 3.2 % and the mean encapsulation ratio was 34.2%. The drug had satisfactory magnetic property. Conclusion: Our method can obtain M-PLGA-PAO-NP with satisfactory quality, it is simple-to-use and the prepared particles can meet the requirement of pharmaceutics..

Acta Anatomica Sinica 2002;0(06):-
Objective To study the regulatory effect of exogenous fibroblast growth factor(FGF\|2) in expressions of calcitonin gene\|related peptide(CGRP) and FGF\|2 in facial motoneurons after injury. Methods The right facial nerve was transected 6?mm distal to the stylomastoid foraman.A 3?mm\+3 piece of Gelfoam presoaked in 25??l of various test solutions(normal saline,or 16?10 6?IU/L FGF\|2,or 32?10 6?IU/L FGF\|2) was implanted adjacent to the proximal nerve stump.After three days survival,the rats were killed and brainstems were removed.Serial 20??m cryosections were cut through the whole brainstem.The CGRP and FGF\|2 immunoreactivity were studied by immunohistochemisty and image analysis. Results An increase in the CGRP and decrease in the FGF\|2 signals were presented in axotomized motoneurons with saline\|treated animals.In FGF\|2\|treated animals,the lesion\|induced up\|regulation of CGRP and down\|regulation of FGF\|2 were attenuated compairing with normal saline treated animals.Conclusion\ Exogenous FGF\|2 can increase FGF\|2 expression and decrease CGRP expression in rat facial motoneurons after injury.\;[

Background Proliferative vitreoretinopathy(PVR) is a tissue repair prevention and treatment of PVR in clinic.Natural delayed release microballoons are therefore becoming a hot spot for its easy manipulation,large lading dose and long acting duration.Objective This study was to evaluate the effect of 5-fluorouracil natural delayed release microballoons on the prevention of PVR.Methods The lymphocytes were collected from clean pigment rabbit to prepare the 8×107/ml cell suspension with complete culture fluid.PVR models were established in 45 healthy pigment rabbits by intravitreal injection of lymphocyte suspension.The animals were randomly divided into 3 groups and 15 rabbits for each.0.1ml normal saline,10g/L or 20g/L 5-fluorouracil natural delayed release microballoons were injected into vitreous cavity respectively.PVR was graded on Fastenberg's method under the slit lamp in 1,2,4,8 weeks.The animals were sacrificed and retinas were obtained for the histopathological and ultrastructural examination in the eighth week after administration of drug.Results The numbers of eyes with different grades of PVR were significantly different among 3 groups in 1 week,2,4,8 weeks(P<0.05).The eye numbers with PVR was significant less in 20g/L Fu group than those of 10g/L Fu group and normal saline group(P<0.05).There was statistical difference in PVR ranking among these 3 groups in 8 weeks after injection of drug(H=46.795,P<0.05).The morphology and ultrastructure of retinas under the light microscope and transmission electron microscope were near normal in all of the three groups.Conclusion Implantation of 5-fluorouracil natural delayed release microballoons into vitreous cavity is effective and safe in preventing PVR in experimental model,and the therapeutic effect of microballoons with 20g/L 5-Fu is better.

Objective To evaluate the clinical efficacy of China-made expanded polytetrafluoroethylene (ePTFE) in the treatment of facial defects and hollow deformities on the face. Methods Facial augmentation was performed in different sites as the forehead, temple, nose, chin, nosal base and maxilla, respectively, to correct the facial defects and hollow deformities, by using either China-made ePTFE (Experimental Group) or imported ePTFE (Control Group). Postoperative parameters between the two groups were compared. Results The Experimental Group included 16 patients (18 sites), in whom the postoperative follow-up was conducted for 6~9 months. In this group, a secondary infection (in the nose) occurred in 1 patient because the implant was placed too superficially and too close proximity to the incision, and the implant was removed out. Delayed healing of the incision (in the chin) with uncovered implant was found in 1 patient, who was cured by the change of dressing. In the rest of the patients, no obvious allergic, inflammatory or rejection reaction was seen and a good cosmetic result was achieved. The satisfactory rate of this group was 94.4%(17/18). The Control Group included 10 patients (20 sites). The implant was found bared and then removed in 1 patient (in the nose). The satisfactory rate of this group was 91.7%(11/12). There were no statistical differences between the two groups in the wound healing ( ? 2 =1 109, P =0 574), the adverse reaction ( P =1 000), and the clinical efficacy ( P =1 000). Conclusions China-made ePTFE gives histocompatibility as good as imported one. It is suitable for filling the soft tissue and can be used as a safe and economical alternative.
