To provide theoretical and practical basis for the successful formulation design of physically-mixed inhalation dry powder of proteins and peptides, related references were collected, analyzed and summarized. In this review drug micronization technology and commonly used carriers for inhalation dry powder preparation were introduced. For proteins and peptides, supercritical fluid technology and spray-drying are more suitable because of their capabilities of keeping drug activity. Being approved by U. S. Food and Drug Administration, lactose has been extensively used as carriers in many inhalation products. Formulation and process factors influencing drug deposition in the lung, including carrier properties, drug-carrier ratio, blending order, mixing methods, mixing time and the interaction between drug and carrier, were elucidated. The size, shape and surface properties of carries all influence the interaction between drug and carrier. Besides, influence of micromeritic properties of the dry powder, such as particle size, shape, density, flowability, charge, dispersibility and hygroscopicity, on drug deposition in the lung was elaborated. Among these particle size plays the most crucial role in particle deposition in the lung. Moreover, based on the mechanisms of powder dispersity, some strategies to improve drug lung deposition were put forward, such as adding carrier fines, adding adhesive-controlling materials and reprocessing micronized drug. In order to design physically-mixed inhalation dry powder for proteins and peptides with high lung deposition, it is essential to study drug-carriers interactions systematically and illustrate the potential influence of formulation, process parameters and micromeritic properties of the powder.

Objective To research the effects of transcutaneous electrical stimulation (TES) on the expression of neurotrophin-3 (NT-3) and tumor necrosis factor-α (TNF-a) in the ventral horn of rats' spinal cords and in the injured region after spinal cord injury (SCI),and to explore the effects of TES on neuron reconstruction and functional recovery and their mechanisms. Methods Forty-eight Wistar rats were selected and divided using stochastic methods into a model group and a TES group.Using Allen's method,a complete SCI model was created at T9.Rats of the TES group were given TES treatment.Basso-Beattie-Brasnahan ( BBB ) ratings were used to evaluate locomotor function.Both groups were sampled at 1,3,5 and 7 days after the operation.Immunohistochemical techniques were used to detect the expression of NT-3 and TNF-α in the rats' spinal cords at the different time points. Results The post-operative BBB ratings of both groups showed an increasing trend.In the TES group the improvement was significantly better at 5 and 7 days than in the model group.The expression of NT-3 immuno-positive cells increased in both groups,peaking at 5 days post-operation,then declining at day 7.The expression of NT-3 positive cells at days 5 and 7 had increased significantly more in the TES group than in the model group.TNF-α immuno-positive expression increased with time in both groups,but in the TES group the expression increased substantially less than in the model group.At days 5 and 7 post-operation,the expression was significantly lower than in the model group. Conclusions TES can promote NT-3 expression in rats with SCI,inhibit the increase in TNF-α expression,and aid repair and reconstruction of neurons and related functional recovery.

The validity of (99m)Tc-YIGSR, a novel receptor radio-tracer, in imaging the Ehrlich ascites tumor was evaluated. YIGSR, a pentapeptide of laminin, was labeled with (99m)Tc by using a bifunctional chelator S-Acetly-NH(3)-MAG(3). The MIBI was labeled with (99m)Tc by following the kit instruction. The mice of tumor group were intravenously injected 1-2 mCi of (99m)Tc-YIGSR or (99m)Tc-MIBI via caudal vein, immobilized and imaged under a Gamma camera. The same procedure was performed in mice of blockade group, in which the unlabeled YIGSR was previously injected to block the receptor-recognition sites, and inflammation group serving as control. The reverse-phase Sep-Pak C(18) chromatogram was found to have an essentially complete conjugation between YIGSR and S-Acetly-NH(3)-MAG(3). The conjugated YIGSR could be radio-labeled successfully with (99m)Tc at room temperature and neutral pH, with a radio-labeling yield of 62%. Without the chelator S-Acetly-NH(3)-MAG(3), the YIGSR was labeled with (99m)Tc at an efficiency of 4%. The imagological study revealed obvious tumor accumulation of (99m)Tc-YIGSR 15 min after the injection, and the uptake peaked after 3 h with a tumor-to-muscle ratio (T/M) of 11.36. The radio-tracer was slowly cleared up and resulted in a T/M of 3.01 at the 8th h after the injection. As for blocked group, the tumor uptake of radiotracer was significantly lower, with the highest T/M being 4.61 after 3 h and 0.89 after 8 h. The T/M was 3.72 at the 3rd h and 1.29 at the 8th h after the (99m)Tc-YIGSR injection in the inflammatory group. The T/M was significantly higher in tumor group than in inflammatory group or control group (P<0.001). In the 99mTc-MIBI group, the T/M was 1.40 at the 3rd h and 0.55 at the 8th h after the injection, which showed a significant difference as compared with (99m)Tc-YIGSR (P<0.001). It is concluded that YIGSR can be successfully radiolabelled by using S-Acetly-NH(3)-MAG(3). (99m)Tc-YIGSR has many advantages in tumor imaging, such as quick and clear visualization, high sensitivity and specificity, and satisfactory target/non-target ratio (N/NT). It promises to be tumor radio-tracer.

Objecttive To observe the repaired effect of distinct source olfactory ensheathing cells (OECs) on spinal cord injury (SCI) rats. Methods These OECs were dissociated from olfactory bulb and olfactory mucosa of SD rats and transplanted to the injuried region of spinal cord injury rats. The function of nerve, motor evoked potential of hind legs and the histopathlogical diversities of injuried spinal cord were observed. Results The OECs grafts into the SCI area could survive longer time. The BBB scale, incubation stage of EP and histopathologic manifestations showed that the group with transplanted OECs regained more improvement in hindlimb than the control group. Conclusion The OECs of two sources have the same ability to regain and improve the axonal function which can promote axons regeneration of SCI.

Using high pressure homogenization method combined with spray-drying, budesonide-loaded chitosan microparticles were prepared and the in vitro release profile was investigated. The microparticles were then blended with lactose using a vortex mixer, influence of mixing speed, mixing time on drug recovery rate and content homogeneity were investigated. Meanwhile, influence of lactose content on drug recovery rate, content homogeneity, powder flowability and in vitro deposition were studied. It turned out that budesonide was released from the microparicles in a sustained manner, with fine particle fraction as high as 46.0%, but the powder flowability was poor. After blending with 10 times of lactose, the drug recovery rate was 96.5%, with relative standard deviation of drug content 2.5%, and fine particle fraction of the formulation increased to 59.6% with good flowability. It's demonstrated that using a vortex mixer, budesonide sustained-release dry powder for inhalation with good recovery and content homogeneity could be prepared, the formulation had good flowability and was suitable for pulmonary inhaling.
