Aim Targeted drug delivery in the brain is the necessary way for the treatment of brain diseases. In our study, a new peptide derived from the rabies vi-rus glycoprotein ( RVG-derived peptide, RDP ) was used as a targeted carrier to modify the curcumin stealth liposomes, and their characteristics and brain targeting effect were studied. Methods The curcumin liposomes were prepared by thin film dispersion. The release test in vitro was conducted to investigate their drug release. Curcumin distribution in several organs of mice was investigated by caudal vein injection of curcumin suspension liquid ( CUR ) , curcumin lipo-somes ( CUR-L) , RDP modified curcumin stealth lipo-somes ( RDP-CUR-L) via HPLC assay at different time points. Results The prepared stealth nano liposomes had a size of around 100 nm, and also had a good dis-persion and reproducibility. The entrapment efficiency was larger than 85%. After caudal vein injection of CUR, CUR-L and RDP-CUR-L in mice respectively, no curcumin was detected in brain of CUR group, and only a little was detected in CUR-L group. Neverthe-less, high concentration of curcumin was detected in RDP-CUR-L group. Conclusion RDP can deliver li-posome into the brain, which may provide a new meth-od for the treatment of brain diseases.

Objective To investigate the status of the rehabilitation service and rehabilitation medical professionals in Tianjin. Methods130 hospitals and Disabled Persons' Federations in Tianjin selected by stratified random cluster sampling were surveyed by questionnaires.Results About 49.2% institutions had carried out the rehabilitation services; there were 842 rehabilitation medical professionals in total, including237 rehabilitation physicians and 3 prosthetic orthopaedic technicians, with a gap of nearly 3000 people; most of them were in loweducation. Conclusion The rehabilitation service should be developed; the quantities and quality of the rehabilitation medical professionalsshould be improved, the classified structure and the service objects are unbalanced.

Patients with hypoxia pulmonary hypertension (HPH) are often accompanied by dyspnea, fatigue, and headache. With the development of the disease, the right ventricle gradually collapses and eventually leads to death. Hypoxic pulmonary vascular remodeling is an important pathological basis of HPH, and the remodeled pulmonary vessels will form permanent thickening. The mechanism of hypoxic pulmonary vascular remodeling is relatively complex. At present, there are few studies on drugs for pulmonary vascular remodeling on the market, mainly focusing on the alleviation of pulmonary vasoconstriction. It was found that hypoxia induces calcium overload in pulmonary artery smooth muscle cells (PASMCs), resulting in the proliferation of PASMCs. The main mechanisms include: ① abnormal expression of calcium pumps; ② abnormal calcium channels in the plasma membrane of pulmonary artery smooth muscle cells; ③ overexpression of calcium-sensitive receptors in cells; ④ the expression of Na⁺/Ca²⁺ exchanger type-1 was abnormal. This review summarized several mechanisms of hypoxia induced calcium overload leading to pulmonary artery remodeling, hoping to provide a new idea for the treatment of HPH.

Objective To explore the methods and mid-term results of interventional therapy for atherosclerotic occlusive disease of the superficial femoral artery(SFA).Methods From January 2005 to August 2008,Nineteen cases with 22 diseased lower limbs were admitted.According to Fontaine stage system,there were 6 stage Ⅱb limbs(moderate to severe intermittent claudication),8 stage Ⅲ limbs(rest pain),and 8 stage Ⅳ limbs(6 with ulcer and 2 with gangrene).The mean lesion length was 8.8 cm(5～13 cm).On the basis of the TransAtlantic Inter-Society Consensus(TASC)femoropopliteal classification,the lesions were classified as type B in 4 limbs,type C in 17,and D in 1.Follow up examinations with color duplex ultrasound and/or arteriography were carried out to determine the patency.The improvement of clinical symptoms after operation was analyzed.Results 17 limbs were revascularization successfully,2 limbs were turned to bypass operation,3 limbs were judged untreatable.The technical success rate is 77.3%,and the clinical improvement of symptoms was achieved in 100% of the 17 limbs on which the procedure was successful.The 17 limbs were followed up for a mean of 12.5 months(range 3-33 months).One patient died of cardia infarction one month postoperatively.SFA occlusion happened in 4 limbs.At one year postoperatively,the patency rate was 75%(13/17)after primary operation.Conclusions Primary endovascular treatment of SFA occlusion diseases is a safe,minimally invasive,and effective method.

Professor LI Zhi-dao, according to acupoint selection of syndrome differentiation in TCM basic theory, concluded a new therapy, namely "tonifying three qi" that is mainly based on three acupoints in the Conception Vessel. This method is consisted of Danzhong (CV 17), Zhongwan (CV 12) and Qihai (CV 6) in the Conception Vessel, which could successively nourish clear qi, stomach qi and original qi. In clinic, according to the severity of symptoms of three qi, the acupoints are selected flexibly, which could respectively treat deficiency of heart-lung qi, deficiency of stomach-spleen qi and deficiency of original qi. Some examples are also given in the article.
