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.

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 application value of the self-rated health measurement scale (SRHMS) in health check-up.Method A total of 8 083 health check-up receivers frow Fujian Province underwent SRHMS self-assessment,and the results of the assessment were analyzed by Chi-square test.Result The results of the survey showed that the total prevalence rate of chronic disease was 57.8％ top five were stomach/duodenum diseases (14.57％),hypertension (11.58％),mammary gland disease (8.04％),abnormal blood lipid (7.16％) and prostate disease (6.54％).The proportion of these five kinds of illness was 43.38％.A positive correlation between the prevalence rate of chronic disease and age was found.The difference of the prevalence rate of chronic diseases between each age group was statistically significant (x2=863.816,P=0.000).Those with family history of chronic diseases accounted for 69.27％ and those with history of present illness accounted for 57.83％ (4 674/8 083).Bodily pain,dietary preferences,refined grain intake,lack of exercise,and alcohol drinking was found in 75.03％,60.15％,54.84％,46.07％ and 41.50％ participants.Conclusion The SRHMS could reflect the chronic disease incidence and unhealthy daily habits.

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 establish a detection method integrating DPRA ( direct peptide reactivity assay) with h?CLAT ( human cell line activation test) to screen the skin sensitization potency of chemicals and plant extracts. Methods 12 chemicals and 7 plant extracts were chosen as the test substances. Firstly, the test substances were incubated together with two different peptides ( cysteine and lysine) respectively for reaction for 24 h. The peptide consumptions were analyzed by HPLC. Simultaneously, THP?1 cells were cultured in vitro and then exposed to different concentrations of test sub?stances for 24 h to examine the cell viability, cell surface markers CD54 and CD86 were assessed by flow cytometry. The predicting results were compared further between DPRA and h?CLAT. Results 12 chemicals were distinguished correctly by DPRA classified as 2 non?sensitizers and 10 sensitizers. The results of DPRA were in accordance with h?CLAT. Predic?ting the sensitization potency of plant extracts by DPRA showed that 6 plant extracts were determined as suspected sensiti?zers except for green tea extract. But using the method of h?CLAT, 4 plant extracts were examined as suspected sensitizers except for green tea extract, herba portulacae extract and ginseng fruit extract. The coherence of DPRA and h?CLAT was 0?57. Conclusion This detection method integrating DPRA with h?CLAT can predict single compound accurately. As for complex compound, it can achieve preliminary prediction and need other integrating methods to make a further identifica?tion.

Objective To evaluate the effect of Shenfu Decoction pretreatment on the function of intestinal mucosal barrier of endotoxemic rats.Methods Twenty-four adult male Sprague-Dawley rats,aged 4-6 months,weighing 180-220 g,were randomly divided into 3 groups (n =8 each):blank control group (group C),endotoxemia group (group E) and Shenfu Decoction pretreatment group (group S).Endotoxemia was induced by lipopolysaccharide 10 mg/kg injected intravenously in anesthetized rats in groups E and S.Normal saline and Shenfu Decoction 5 ml/kg were injected intraperitoneally at 30 min before the model of endotoxemia was established in groups E and S,respectively.At 2 h after the model of endotoxemia was estabhshed,blood samples were obtained from the abdominal aorta for measurement of the plasma concentrations of tumor necrosis factor-α (TNF-α),interleukin6 (IL-6),intestinal fatty acid binding protein (i-FABP) and diamine oxidase (DAO) by ELISA.The distal ileum was harvested for detection of the expression of tight junctional protein Zonula Occludens-1 (ZO-1) in the intestinal mucosa of epithelial cells by immunohistochemistry.The changes in pathological morphology of the intestinal mucosa were examined after one segment of the distal ileum was stained with haematoxylin and eosin.The pathological changes were assessed and graded according to Chiu's score.Results Compared withgroup C,the plasma TNF-α,IL-6,i-FABP and D-lac concentrations were significantly increased,Chiu's scores were increased,and the expression of ZO-1 was down-regulated in groups E and S (P ＜ 0.05).Compared with group E,the plasma TNF-α and IL-6 concentrations were significantly decreased,the plasma i-FABP and D-lac concentrations were decreased,Chiu's scores were decreased,and the expression of ZO-1 was up-regulated in group S (P ＜ 0.05).Conclusion Shenfu Decoction pretreatment can attenuate the damage to the intestinal mucosa and protect the function of intestinal mucosal barrier in endotoxemic rats and inhibition of systemic inflammatory responses is involved in the mechanism.

Objective: To observe the influence of transcutaneous CO2emission (TCE) at points on the meridian or beside the meridian after different stimulations like acupuncture De-qi, sham acupuncture, study the correlation between acupuncture De-qi and local energy metabolism through TCE. Methods: Twenty healthy volunteers (male 8, female 12, average age 29 years old) were selected. Before, during and after five different acupuncture Neignan (PC 6), the TCE was measured at Quze (PC 3), point A [at the lower one fourth of line between Tianquan (PC 2) and Quze (PC 3)], point B [at the middle of line between Ximen (PC 4) and Quze (PC 3)], point C (2 cm ulnar side point A) and point D (2 cm ulnar side point B) with a high sensitive C02 instrument (Frewil-Q.F., made in China). The measure results were compared. Results: The comparison on value of TCE before and after the acupuncture, in Sham acupuncture and shallow acupuncture groups, it increased in all five points; in De-qi acupuncture group, there are significant increase on point A, point B, and Quze (PC 3), it has statistic significance, but there are no significant increase on point C and D. After Ximen (PC 4) or Daling (PC 7) were pressed to block Neiguan (PC 6), the value of TCE on Quze (PC 3), point A and point B were decreased during acupuncture Neiguan (PC 6), and increased after the block was removed, but there was no significant difference. Conclusion: Sham acupuncture has also some effects on body, it can increase energy metabolism of local skin, it may be the reason that shallow acupuncture without qi amving can obtain clinical efficacy. The operation method of traditional qi arriving acupuncture can increase energy metabolism of relevant meridian skin, mechanical press can reduce this effect.
