ObjectiveTo develop an experimental model of orthostatic hypotension (OH) after spinal cord injury (SCI) in rabbits and investigate the effect of tilting table exercise and Shengmaiyin on it. MethodsRabbit model of OH after SCI were induced by complete transection of spinal cord at the T5 spinal segment and raised to 60° head up tilt (HUT) on a tilting table. Tilting table exercise and Shengmaiyin were applied to different groups for 28 d from 4 days after operation. Systolic blood pressure (SBP) and pulse rate (PR) were observed with non-invasive sphygmobolometer of rabbit 3, 10, 17, 24, 31 d after the operation. Liquid chromatography with electrochemical detection(HPLC-ECD) was used to detect the concentrations of plasma norepinephrine (NE) and epinephrine(E) with horizontal position and HUT 60° on the 31st day. ResultsSBP with HUT 60° in rabbits of combined treatment group was significantly higher than that in rabbits of SCI group on the 24th day after operation,and the drop in SBP from horizontal position to HUT60° was significantly lower than that in rabbits of SCI group. SBP with HUT 60° in rabbits of exercise group and combined treatment group was significantly higher than that in rabbits of SCI group on the 31st day after operation. The drop in SBP from horizontal position to HUT 60° was significantly lower in rabbits of Shengmaiyin group, exercise group and combined treatment group than that in rabbits of SCI group on the 31st day after operation. The concentration of E and NE of SCI group, Shengmaiyin group, exercise group and combined treatment group was lower than that of sham group, but there was no significant difference among these groups. ConclusionThe treatment with tilting table exercise and Shengmaiyin can improve OH after SCI partially in rabbits without involving norepinephrine and epinephrine significantly. The period of treatment can be shorten when both therapies used together.

The aim of this study is to develop the Tripterygium glycosides nanoemulsion gels and investigate its pharmacodynamics. Oleic acid was used as oil phase, polyoxyethylene castor oil as surfaetant, and 1,2-propanediol as cosurfactant to screen the formula of Tripterygium glycoside nanoemulsion using the pseudo-temary phase diagrams. Then the nanoemulsion gels was prepared. The ICR mouse ears were sensitazated by 7% DNCB, and then were excited by 0.3% DNCB to stimulate the model of mouse chronic dermatitis and eczema. The concentrations of IFN-γ, IL-4 and IL-8 in mouse blood were determined by ELISA. The results showed that Tripterygium glycosides nanoemulsion gels could significantly inhibit the swelling of mouse ears(P < 0.01) and ameliorate the edama and erythema of model mouse ears skin. Also it could significantly decrease the expression of IFN-γ and IL-4 in model mouse blood. Tripterygium glycosides nanoemulsion gels had a good therapeutic effect on mouse model of dermatitis and eczema. It was expected to provide a new and long-acting exterernal preparation for the treatment of dermatitis and eczema.

Abstract: Transfection of Plasmodium falciparum is helpful to study the function of its genes, such as drug resistance. However, transgenic manipulation has been very challenging, mainly due to the high A/T base sequence structure (A+T content of about 82%) and low transfection efficiency of the Plasmodium genome. Electroporation-based transfection of Plasmodium falciparum has been successfully applied in the study of certain genes, and electroporation by preloading is currently the preferred method for introducing foreign DNA into Plasmodium falciparum. The site-directed editing of Plasmodium genes mostly adopts the method of two-plasmid transfection. It is generally believed that successful transfection of Plasmodium requires a large amount of high-purity plasmid DNA and an accurate transfection system. In addition to the evaluation of the current commonly used electrotransfection methods, this paper also introduces a new transfection method, namely lyse-reseal erythrocytes for transfection (LyRET). This paper also review the role of factors such as plasmid DNA concentration, the use of transfection reagents, the setting of transfection parameters, the addition of fresh red blood cells, and the markers of successful transfection in improving the success rate and efficiency of Plasmodium transfection, in the hope of providing a reference for study in this field.

In view of the effective traditional Chinese medicine (TCM) in the treatment of clinical depression, the mechanism is not clear, this study attempts to research the cause of depression in a complex situation to lay the foundation for the next step of TCM curative effect evaluation. Based on the brain wave of 120 depression patients and 40 ordinary person, the change regulation of acetylcholine, dopamine, norepinephrine, depression neurotransmitters and excited neurotransmitters in the whole and various encephalic regions' multi-neurotransmitters of depression patients-serotonin are analysed by search of encephalo-telex (SET) system, which lays the foundation for the diagnosis of depression. The result showed that: contrased with the normal person group, the mean value of the six neurotransmitters in depression patients group are: (1) in the whole encephalic region of depression patients group the dopamine fall (P < 0.05), and in the double centralregions, right temporal region and right parietal region distinct fall (P < 0.01); (2) in the right temporal region of depression patients group the serotonin rise (P < 0.05); (3) in the right central region, left parietal region of depression patients group the acetylcholine fall (P < 0.05), left rear temporal region fall obviously (P < 0.01). The correlation research between antagonizing pairs of neurotransmitters and neurotransmitters: (1) the three antagonizing pairs of neurotransmitters-serotonin and dopamine, acetylcholine and norepinephrine, depression neurotransmitters and excited neurotransmitters, in ordinary person group and depression patients group are characterizeed by middle or strong negative correlation. Serotonin and dopamine, which are characterized by weak negative correlation in the right rear temporal region of ordinary person group, are characterized by strong negative correlation in the other encephalic regions and the whole encephalic (ordinary person group except the right rear temporal region: the range of [r] is [0.82, 0.92], P < 0.01)/(depression patients group:the range of [r] is [0.88, 0.94], P < 0.01); acetylcholine and norepinephrine, in the whole and various encephalic region are characterized by middle negative correlation(ordinary person group:the range of [r] is [0.39, 0.76], P < 0.01 or P < 0.05)/(depression patients group: the range of [Ir] is [0.56, 0.64], P < 0.01); depression neurotransmitters and excited neurotransmitters are characterized by middle strong negative correlation (ordinary person group: the range of [r] is [0.57, 0.80], P < 0.01)/(depression patients group: the range of [r] is [0.68, 0.78], P < 0.01). (2) The two neurotransmitters which are not antagonizing pairs of neurotransmitters, serotonin and excited neurotransmitters, or acetylcholine and depression neurotra-nsmitters, or dopamine and depression neurotransmitters in the various encephalic regions are characterized by weak negative correlation. Serotonin and excited neurotransmitters are characterizeed by weak negative correlation (ordinary person group: in the right central region, left parietal region, double front temporal regions, right rear temporal region, the range of [r] is [0.25, 0.50], P < 0.01 or P < 0.05)/(depression patients group: in the whole encephalic regions, double parietal regions, double occipital regions, right front temporal region, left central region, left frontal region, the range of [r] is [0.18, 0.37], P < 0.01 or P < 0.05); acetylcholine and depression, neurotransmitters are characterized by weak negative correlation (ordinary person group: in the double frontal regions, left parietal region, left front temporal region, right rear temporal region, the range of [r] is [0.31, 0.46], P < 0.01 or P < 0.05)/(depression patients group: in double rear temporal regions, right front temporal region, double occipital regions, left central region, the range of [r] is [0.20, 0.32] , P < 0.01 or P < 0.05); do-pamine and depression neurotransmitters are characterized by weak middle negative correlation (ordinary person group: in left parietal region, right central region, left frontal region, left occipital region, double front temporal regions, the range of [r] is [0.33, 0.68], P < 0.01 or P < 0.05)/(depression patients group: in the whole region and other various regions except the left frontal region, right central region, the range of Irl is [0.21, 0.34], P < 0.01 or P < 0.05). Dopamine and acetylcholine or norepinephrine and serotonin are characterized by weak positive correlation in all encephalic regions. Dopamine and acetylcholine are characterized by weak positive correlation (ordinary person group: in left frontal region, right parietal region, left front temporal region and left rear temporal region, the range of [r] is [0.37, 0.46], P < 0.01)/(depression patients group: in the whole region and the orther various regions except the double central regions, the range of [r] is [0.23, 0.5], P < 0.01 or P < 0.05); norepinephrine and serotonin are characterized by weak positive correlation (ordinary person group: in double front temporal regions, double rear temporal regions, right frontal region and left parietal region, the range of [r] is [0.34, 0.48], P < 0.01 or P < 0.05)/(depression patients group: in the whole and various regions, the range of [r] is [0.18, 0.42], P < 0.01). The main differences between the depression patients group and ordinary person group are: (1) In the whole regin, left frontal region and right central region of depression patients group, the six neurotransmitters all fall normally (P < 0.05). (2) The percent of dopamine falling or including dopamine falling, or including dopamine falling and serotonin rising in depression patients group increases. The percent of dopamine falling or including dopamine falling in the whole region, right frontal region, right central region increases (P < 0.01), such as dopamine decreasing, serotonin increasing dopamine decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing, dopamine decreasing norepinephrine increasing depression neurotransmitters decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing neurotransmitters increasing and so on. (3) The percent of acetylcholine falling, or including acetylcholine falling, or including acetylcholine falling and neurotransmitters (beta)-receptor)rising in depression patients group increases. The percent of acetylcholine falling, or including acetylcholine falling in the right temporal region, double central regions increases (P < 0.05 or P < 0.01), such as acetylcholine decreasing, acetylcholine decreasing neurotransmitters increaseng, acetylcholine decreasing neurotransmitters increasing depression neurotransmitters decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing neurotransmitters increasing and so on. It's showed in research that depression patients' brain are characterized by multi-neurotransmitters abnormal, the synchronous change of multi-neurotransmitters has some certain regularities, which are not the simple linear relation. It's conformed that the three antagonizing pairs, neurotransmitters-serotonin and dopamine, acetylcholine and norepinephrine, depression eurotransmitters and excited neurotransmitters of ordinary person group and depression patients group, are both characterized by strong antagonizing relation, that the two neurotransmitters which are not antagonizing pairs of neurotransmitters are characterized by weak positive correlation or negative correlation, prompt maybe has the indirect causal relationship. And the change of six neurotransmitters in depression patients' various encephalic regions is rather complex. It's conformed preliminarily that the right frontal region and right central region are characterized by dopamine decreasing, acetylcholine decreasing, serotonin increasing dopamine decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing, dopamine decreasing norepinephrine increasing excited neurotransmitters decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing neurotransmitters increasing, acetylchoine decreasing neurotransmitters increasing, acetylcholine decreasing neurotransmitters increasing excited neurotransmitters decreasing and so on. Contrasted with the ordinary person group, the depression patients group have the notable difference.
