Objective To summarize the published studies of diabetic cerebral infarction treated by integration of traditional and western medicine (ITWM) or pure western medicine and compare their clinical curative effects. Method The clinical study of ITWM for diabetic cerebral infarction were collected and seleted according to the standard. The effect of ITWM and only western medicine was compared, and Meta-analysis was made. Result 59 studies were included to analysis neurological deficit and the total efficiency. Meta-analysis revealed that the improvement of ITWM is better than pure western medicine treatment. Conclusion The existed limited evidences suggest that ITWM treatment of diabetic cerebral infarction can significantly improve neurological deficit and curative effect. More high-quality randomized, double-blind, placebo-controlled trials are needed to confirm the efficacy and safety of ITWM treatment of diabetic cerebral infarction.

It is reported that polyethylene glycol-lipid (PEG-lipid) derivatives increase liposomes stability, prolong the blood circulation of liposomes, enhance their tumor-targeting efficiency, and improve drug efficacy. Therefore, it is of great importance to investigate the influence of modified PEG-lipid derivatives on the physical, chemical, and biological characteristics of liposomes for the promotion of dealing with the existed problems, such as the accelerated blood clearance (ABC) phenomenon when repeated intravous injection at a certain time-interval, and developing novel targeted pharmaceutical preparations. In this review, the effects of modified PEG-lipid derivatives were summarized in many aspects. It indicats that the chemical bonds (amide, ether, ester, and disulfide) between PEG and lipid, as well as the species of lipids, such as the commonly used phosphatidylethanolamine, cholesterol, and diacylglycerol have substantial effects on the grafted liposomes stability in vitro and in vivo. Besides, the properties of lipids (the fatty acid chain length and saturation) and the groups (methoxy, carboxylic and amino) at the distal ends of the PEG chains were also considered to be important factors. In the end, the influence of the average molecular weight of PEG and the molar ratio of PEG-lipid derivatives in the total lipid were further focused.

Objective To investigate the effects of Ziyin Huoxue Jiedu Chinese herbs(ZYHXJD) on vascular endothelial cells injured by glucose,insulin and low-density lipoprotein.Methods Human umbilical vein endothelial cell line ECV-304 was exposed to different concentration of glucose,insulin and oxidized low-density lipoprotein(Ox-LDL),and the effects of ZYHXJD on the injured vascular endothelial cells were investigated.The cells in each group were cultured for additional 48 h.And then,cell viability was examined,and the supernatants were used to determine the contents of tissue plaminogen activator(tPA),plasminogen activator inhibitor(PAI),and intercellular adhesion molecule-1(ICAM-1) respectively.Results The viability of the cells in the model group decreased markedly(P

Polymeric micelles which are self-assembled from amphiphilic copolymers are thermodynamically stable, and they can solubilize hydrophobic drugs by the hydrophilic core. Many excellent active compounds are confined because of general low oral bioavailability due to poor solubility. Take into account from the two points above, polymeric micelles may be used as proper oral carrier to improve the dissolubility of hydrophobic drugs, and enhance the permeation though gastrointestinal tract, therefore, the pharmacodynamics is elevated. Meanwhile, the segments in copolymers are multivariate, so many kinds of micelles can be obtained, such as, pH- or thermo- sensitive as well as mucoadhesive ones. The modified micelles can alter drug release profiles while solubilizing them, that is why the oral bioavailability increase further. In this review, recent progress of polymeric micelles used in oral administration is summarized, and the prospect of polymeric micelles' application in this field is also evaluated.

It is generally believed that liposomes modified with polyethylene glycol (PEG) have no or lower immunogenicity. However, based on many recent literatures, when the PEGylated liposomes were repeatedly applied to the same animal, the immune responses occurred. The first injection of PEGylated liposomes resulted in a reduction in the circulation time and an increase in hepatic and splenic accumulation of the second dose of PEGylated liposomes in a time-interval, which was called "accelerated blood clearance (ABC)" phenomenon. Such immunogenicity of PEGylated liposomes presents a barrier in the research of liposomal formulations and their use in the clinics. This review focused on the definition, the method of verification, the development of the reason for ABC phenomenon, influencing factors of ABC phenomenon, and discussed if other PEGylated nanocarriers also induce ABC phenomenon.

Objective　To observe the curative effect and sid e effect of the gastrokinetic agent mosapride citrate by RCT. Methods　 42 cases of functional dyspepsia (FD) were divided into two groups rando mly, the group of mosapride(21 cases):orally administrated mosapride, 5mg, t.i.d for 4 weeks, and the control (21 cases):orally administrated domperidone, 5mg, t.i.d for 4 weeks. Symptoms and side effects were recorded before and at d 14, d 28 after administration of the medicines according to GCP and double blind pri ciple.

Polyethylene glycol (PEG) is extensively used to increasing the in vivo and in vitro stability of liposomes. However, PEGylated liposomes also produce some negative effects with further research, such as low cellular uptake, poor "endosomal escape" of pH sensitive liposome (PSL) and accelerated blood clearance (ABC) phenomenon, and this situation is referred as the "PEG dilemma". "PEG dilemma" posed severe challenges for the targeted delivery of PEGylated liposomes-loaded anticancer drugs, effective intracellular release of PEGylated PSL-encapsulated gene and protein drugs, and repeated administration of PEGylated liposomes. Therefore, it is urgent to solve the "PEG dilemma". This review focused on the definition, classification of "PEG dilemma", and discussed several possible approaches to overcome "PEG dilemma".

Objective To investigate the expression of β-catenin and Oct-4 in colonal carcinoma and explore the relationship with recurrence and metastasis after operation. MethodsImmunohistochemical analysis was used to evaluate the expression of β-catenin and Oct-4.The correlation of β-catenin and Oct-4 expression with tumor cell differentiation,T stage,N stage and metastasis was analyzed.The gene expression of Oct-4 was examined by RT-PCR in 20 frozen tumor tissues and normal tissues adjacent to tumor.Results Thirty-five patients had metastasis. The positive rates of β-catenin and Oct-4 expression were significantly higher in metastasis group than in the non-metastasis group (65.71％ vs 31.11％,51.43 ％vs 13.33 ％,x2 =9.843,P =0.002,x2 =13.605,P =0.001).Expression of β-catenin and Oct-4 was not associated with differentiation,T stage or N stage.The positive expression rate of Oct-4 in colonal carcinoma tissues was significantly higher than that in normal tissues.Metastatic rates in patients with positive expression of β-catenin and Oct-4 was higher than that in negative expression.The survival analysis showed that time of metastasis was significantly different in two groups of patients (P ＜0.05).Conclusion The expression of β-catenin and Oct-4 in tumor tissues is related to metastasis of colonal cancer after surgery and might be used to predict metastasis of colonal cancer after operation.

Objective: To observe the safety of the Song-Relaxing and Zhen-Vibrating abdomen manipulation in treating patients with prediabetes and its effects on blood glucose and lipid metabolism.Methods: One hundred and two patients with prediabetes were divided into a manipulation group and a control group according to the random number table method, with 51 cases in each group. All patients received the general behavioral intervention for prediabetes, with additional Song-Relaxing and Zhen-Vibrating abdomen manipulation in the manipulation group and oral metformin hydrochloride tablets in the control group. Both groups received the intervention for six months. Results: Fourteen patients dropped out during the treatment, and a total of 88 patients completed the trial, including 45 cases in the manipulation group and 43 cases in the control group. After the treatment, the prediabetes control rate was 93.3％ in the manipulation group and 74.4％ in the control group, and the difference between the two groups was statistically significant (P<0.05); no patient in the manipulation group progressed to diabetes, while the rate of conversion to diabetes in the control group was 6.9％, with a significant difference between the two groups (P<0.05). After the treatment, the body mass index (BMI), glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), 2-hour postload plasma glucose (2hPG) level during an oral glucose tolerance test (OGTT), fasting insulin (FINS), homeostasis model assessment-2 of insulin resistance (HOMA2-IR), total cholesterol (TC), and triglycerides (TG) decreased in both groups versus baseline, with significant differences within the groups; the levels of all indicators were lower in the manipulation group than in the control group (P<0.05), and the differences between the two groups were more prominent at the sixth month (P<0.01). At the sixth month, the high-density lipoprotein cholesterol (HDL-C) in the manipulation group was increased, while there was no significant change in the control group. In the control group, three patients reported mild gastrointestinal reactions at the initial dosing, which improved after medication adjustment. No other adverse events were observed in either group. Conclusion: Both metformin hydrochloride tablets and the Song-Relaxing and Zhen-Vibrating abdomen manipulation can improve blood glucose and lipid metabolism and reduce insulin resistance and clinical discomfort in patients with prediabetes, but the Song-Relaxing and Zhen-Vibrating abdomen manipulation has higher efficacy and safety.
