Objective To evaluate the effect of collagen shield delivering fluconazole eye drops made by centrifugal method on treating fungal keratitis of rabbit eyes.Methods Using centrifugal method to make corneal collagen shield,after soaked with fluconazole eye drops,the collagen shields were used to treat fungal keratitis of rabbit eyes.Results The healing focus time of collagen shield delivering fluconazole eye drops group was average 11 days,the healing focus time of only delivering fluconazole eye drops group was average 18 days.The cure rate and effective rate of 2 groups were 78.94%,63.15% and 92.10%,78.94%,there were significance between 2 groups(P<0.05).Conclusion It was innovation for corneal collagen shield delivering fluconazole eye drops made by centrifugal method to cure fungal keratitis,which had broad development foreground.

OBJECTIVETo investigate the mechanism that the formulas for activating blood and resolving stasis can regulate hemopoietic stem cell to produce new blood.

METHODRats were established animal model of acute cerebral infarction by referencing Olivette' method. They were randomly divided into model group, the group of the high, middle, low dose of the formulas for activating blood and resolving stasis. Each group and then wasrandomly divided into subgroups by 1, 3, 7, 14, 28 d. Xuesaitong capsule was formulated into 20, 40, 60 g x L(-1) with normal saline. The rats were given gavage drugs once a day until the experient ended, and the model group was administrated by intragastrical perfusion of normal saline. ELISA was used to detect the expression of SCF in peripheral blood and bone marrow among different groups at different time points. Flow cytometry was used to observe the changes of CD117 in blood and bone marrow.

RESULTThe CD117+ HSC and SCF concentration in peripheral blood and bone marrow of model group were increasing during 1-14 d,there was a peak on the 14th day, then the expression was reducing. CD117+ HSC and SCF concentration rising trend in the group of the high, middle dose of the formulas for activating blood and resolving stasis was preceded model group (P < 0.05).

CONCLUSIONActivating blood and resolving stasis can regulate hemopoietic stem cell to produce new blood, and it is through the regulation of CD117+ HSC number to achieve the purpose.

In patient with primary biliary cirrhosis,the metabolism of calcium and vitamin D could be affected and osteomalacia and secondary hyperparathyroidism might occurr.Besides,hypoalbuminemia may mask the real level of serum calcium and thus lead to misdiagnosis of coexisting parathyroid adenoma.Therefore,a rare case of parathyroid adenoma associated with primary biliary cirrhosis was herewith presented to call attention to the effect of hypoalbuminemia on serum calcium.

Objective To investigate the effect of dexmedetomidine on excitatory aminoacid (EAA)and inhibition of amino acid(IAA)in cerebro-spinal fluid(CSF)of patients undergoing in-tracranial tumor surgery,and to explore the cerebral protective mechanism of dexmedetomidine in neurosurgery.Methods Sixty patients aged 18-64 years old,ASA Ⅰ or Ⅱ,weighing 50-90 kg un-dergoing elective intracranial tumor surgery were randomly divided into dexmedetomidine group (group D)and control group(group C).Dexmedetomidine 1 μg/kg was infused before anesthesia in-duction for more than 10 minutes and pumped continously with 0.2-0.7 μg·kg-1·h-1 in group D, while in group C midazolam 0.03-0.05 mg/kg was injected followed by intermittent administration of 0.03-0.05 mg/kg.BIS value was maintained between 40-50.MAP and HR was recorded at the time points before induction(T0 ),dura mater incision(T1 ),tumor resection(T2 ),at the end of the surgery (T3 ).And we collected CSF at T0 ,T3 ,6 hours after the surgery(T4 ),12 hours after the surgery (T5 ),24 hours after the surgery(T6 ),then the concentrations of EAA and IAA were determined with high-performance liquid chromatography (HPLC)at T0 ,T3 ,T4 ,T5 and T6 .Results The MAP and HR in group D at T1-T3 were much lower than that in T0 and in group C(P <0.05).Compared with T0 ,the Glu and Asp in CSF significantly increased in group C at T3-T6 and were much higher than those in group D (P < 0.05 ),GABA was significantly decreased and much lower than group D(P <0.05).Compared with T0 ,the Glu and Asp in group D at T3-T5 were increased and GABA was decreased, but without statistic significance. At T6 , the values recovered to the level at T0 . Conclusion Dexmedetomidine can be used to maintain hemodynamic stability in intracranial tumor surgery,and may play a role in cerebral protection through inhibiting expression of Glu and Asp (EAA).

Objective To observe the iffectiveness of comprehensive rehabilitationinterventions on stroke patients with unilateral spatial neglect (USN). Methods A total of 245 cases if strijd were examined to diagnose USN. Of the 245 patients,86 cases were diagnosed as being with USN, and divided into a control group(n=43 cases) and a treatment group (n=43 cases) randomly. The control group was treated with Bobath and Rood techniques in addition to routine clinical medical interventions, while the treatment group was treated with a comprehensive rehabilitation protocol for USN in addition to the same interventions for the control group. Both groups were assessed with regard to motor, balance function, walking performance, and USN severity as well as the activities of daily living (ADL) performance. Results After 8 weeks of treatment,both groups improved, but there showed a significantly statistical difference between the 2 groups in terms of Fugl-Meyer motor function scores (P＜0.01), balance function scores (P＜0.01) Holden walding function classifications (P＜0.01), Barthel index(P＜0.001) and USN severity scores(P＜0.01). Conclusion Comprehensive USN rehabilitation intervention could improve motor, balance, walking functions and ADL performance and alleviate the USN severity in stroke patients with USN.

Objective To investigate the early clinical outcome of peripheral cutting balloon(PCB) in the management of peripheral vessel stenosis.Methods Thirteen patients with peripheral limb vessel stenosis, in which 4 stenoses in hemodialysis access and 9 at lower limb arteries,underwent angioplasty by PCB.For multiple stenosis in the same vessel,the distal one should be expanded firstly.The balloon pressure was controlled in the range of 8 atm to 10 atm(1 atm=10.108 kPa).All the patient were given continuous anticoagulant therapy after the procedure.Results All the procedure were carried out successfully on the 13 patients,and no serious complications occured.The symptoms did not recur in all patients after the procedure.The 5 months' follow-up angiography proved that no restenosis occurred in one patient with previous stenosis at the hemodialysis access.Conclusion The angioplasty with PCB was a safe and reliable procedure in management of the peripheral limb vessel stenosis.The early outcome is satisfying.

Tetradrine-tashionone II(A)-PLGA composite microspheres were prepared by the SPG membrane emulsification method, and the characterization of tetradrine-tashionone II(A) -PLGA composite microspheres were studied in this experiment. The results of IR, DSC and XRD showed that teradrine and tashionone II(A) in composite microspheres were highly dispersed in the PLGA with amorphous form. The results of tetradrine-tashionone II(A) -PLGA composite microspheres in vitro release experiment showed that the cumulative release amounts of tetradrine and tashionone II(A) were 6.44% and 3.60% in 24 h, and the cumulative release amounts of tetradrine and tashionone II(A) were 89.02% and 21.24% in 17 d. The process of drug in vitro release accorded with the model of Riger-Peppas. Tetradrine-tashionone II(A) -PLGA composite microspheres had slow-release effect, and it could significantly reduce the burst release, prolong the therapeutic time, decrease the dosage of drugs and provide a new idea and method to prepare traditional Chinese medicine compound.
