This study aims to construct inactivated coxsackievirus A16 (CVA16) vaccine and to investigate its protective effect in ICR mice. A clinical isolate of CVA16, 521-01T, was cultured in VERO cells, inactivated by formaldehyde, and purified by ultracentrifugation for vaccine preparation. Purity and other characteristics of the vaccine were determined by SDS-PAGE and Western blot. Female ICR mice were subcutaneously inoculated with inactivated CVA16 or Al(OH)3-absorbed CVA16, followed by booster immunization at the end of 2 and 4 weeks. CVA16-specific IgG titers in serum were determined by ELISA, and titers of neutralizing antibodies were determined by viral neutralization assay. The immunity of T lymphocytes was evaluated by IFN-gamma ELISPOT assay. The protective effect was evaluated by challenging the neonatal offspring (< 48 hours) of vaccinated female mice with 1 000 LD50 of CVA16 521-01T. The mortality rates of different groups were compared. The results showed that Al(OH)3 +CVA16 could induce high titers of specific IgG antibodies in ICR mice. After being boosted two times, the serum IgG antibody titer could reach up to 1 : 1 x 10(5) (P = 0.000), and neutralizing antibody titer was higher than 1 : 256. Additionally, more spot forming cells were induced in the immunized groups than in the negative controls. The maternal antibodies showed protective effect in 100% of the neonatal mice challenged with 1 000 LD50 of CVA16 521-01T. The inactivated CVA16 vaccine has ideal immunogenicity and immunoprotective effect. This research lays a foundation for the development and evaluation of CVA16 vaccines.

BACKGROUND:Preliminary studies of our research group mainly focus on the role of nucleus of solitary tract in gastric noxious stimulation and acupuncture point, while dorsal nucleus of vagus nerve, nucleus of solitary tract and area postrema are the necessary component for vagus nerve complex, and dorsal nucleus of vagus nerve plays a crucial role in the regulation of gastric functions. OBJECTIVE:To observe the effect of acupuncture at Zusanli, Neiguan, Pishu and Shenshu acupoints on the gastric-related neurons in dorsal motor nucleus of the vagus nerve. METHODS:The gastric related neurons in dorsal motor nucleus of the vagus nerve of gastric distension rats were identified using extracellular recording technique, according to neuroelectrophysiology method. Acupuncture stimulation was given to Zusanli, Neiguan, Pishu and Shenshu for 15 seconds. The effect of body stimulation on the gastric distension related neurons in dorsal motor nucleus of the vagus nerve of rats was recorded. RESULTS AND CONCLUSION:Among the involved 24 rats, 90 neurons at paraventricular hypothalamic necleus exhibited discharge. Among the discharged neurons, 54 neurons were related to gastric distension. After acupuncture stimulation at Zusanli, Neiguan, Pishu and Shenshu, there were 44, 39, 38, 27 neurons giving a response, the reaction rate was 82%, 72%, 70%and 50%, respectively. Acupunture at different nerve segment acupoints can activate the dorsal motor nucleus of the vagus nerve to different degrees, which is involved in the regulation of gastric motility.

Objective To discuss correlation of hemodynamic changes and portal vein diameter with multi-slice spiral CT peffusion imaging in liver cirrhosis. Method 31 cases liver cirrhosis were enrolled in this study. The first porta hepatis were selected for target lay of CT perfusion scan. Liver perfusion parameters were obtained by color perfusion map method. Right to left diameter and occipitofrontal diame-ter of portal vein were measured. 30 cases of normal persons were used as control group. Result Hepatic arterial perfusion (HAP) in liver 0.05). Hepatic perfusion index (HPI) were (19.13±3.33)% and (20.61±8.56)%, which had no statistically significant difference with the other two groups (P>0.05). Conclusion Multi-spiral CT perfnsion imaging is an effectively noninvasive method to evaluate the hemodynamic changes of liver cirrhosis. Occipitofrontal diameter of portal vein with liver cirrhosis can reflect the state of liver hemodynamics.

BACKGROUND:Previous studies concerning neuromechanism of acupuncture for regulating gastric function mainly focused on peripheral nerve, involving in central nervous system. In particular, there are few studies addressing higher central nervous system.
OBJECTIVE:To explore the effects of acupuncture at Neiguan (PC6) and Zusanli (ST36) on gastric-related neurons in the hypothalamic paraventricular nucleus.
METHODS:Using microelectrode extracellular recording technique, gastric related neurons in the paraventricular nucleus were found in gastric distension rats. Stimulation was conducted for 30 seconds by hand acupuncture at Neiguan and Zusanli. The effects of acupuncture on gastric-related neurons in the paraventricular nucleus were observed.
RESULTS AND CONCLUSION:The discharge of 109 neurons in the hypothalamic paraventricular nucleus of 60 rats was recorded. A total of 56 gastric-related neurons of the 109 neurons were observed. The number of neurons response to acupunctures at Zusanli, Neiguan, Pishu (BL20) and Weishu (BL21) were respectively 44, 47, 29, and 33, with the reaction proportion of 78.57%, 83.47%, 51.79%and 58.93%. Results suggested that there exist gastric distension stimulation and acupuncture stimulations from neurons soma to visceral reaction in the hypothalamic paraventricular nucleus, which simultaneously participates in the regulation of acupuncture on the gastric function.

The contents of schisandrol A, schisandrol B, schisantherin A, schisandrin A , schisandrin B, schisandrin C in Schisandrae Chinensis Fructus (SCF) were determined simultaneously by HPLC. Collect 100-seed weight, color, pulp content, longitude and latitude of SCF of different batches were collected. SIMCA-P and SPSS were applied to make PLS-DA analysis of 24 batches of SCF and correlation analysis of relevant parameters. According to the 13 parameters, SCF from three different places of origin could be distinguished effectively. It was found that the content of chemical component of SCF increased with latitude and longitude first, and then decrease. The results provide some theoretical basis for study of SCF genuineness and traditional method of identifying just from experience.

The specification of decoction pieces and quality uniformity are the important factors to influence the efficacy of clinical medicine. Considering the deficiency of diversity, poor quality uniformity and confusion of decoction pieces specifications, we first propose a new idea of precision decoction pieces (PDP) based on clinical demands and fresh-processed technology. In order to explain the idea, a study case of aconite SUP is provided, including the optimized specification design, processing technology, extraction effects, quality uniformity, and toxic and efficacy variation and so on. The results showed that preparing 5 mm PDP by fresh-cutting is rather simple and practicable, with high efficiency and large yield; then, this technology could significantly decrease the ingredients loss and increase the efficacy components; moreover, it was helpful for achieving the quality uniformity and best extraction effects. This work revealed the quality superiority of PDP, and provided a good strategy and example for the standard of decoction pieces specification and modernization of processing technology.
