OBJECTIVETo observe the effect and safety of plastering Chinese Compound Shenhuang Ointment (CSO) at Shenque (RN8) in promoting the rehabilitation of postoperative gastrointestinal dysfunction patients of qi stagnation blood stasis syndrome (QSBSS).

METHODSA prospective, multi-centered, randomized, double-blinded, controlled trial was conducted in 220 postoperative gastrointestinal dysfunction patients of QSBSS. They were randomly assigned to two groups, the CSO group (110 cases) and the placebo group (110 cases). CSO was plastered at Shenque (RN8) for 5 days after operation. The time of exhaustion, defecation, the recovery of intestinal peristalsis, integrals of TCM syndrome, and serum levels of motilin (MOT)and somatostatin (SS) were observed.

RESULTSCompared with the placebo group, the condition of exhaustion and defecation, the recovery of intestinal peristalsis on the 3rd day after operation was all improved (P < 0.05). The integrals of TCM syndrome at day 2, 3, and 4 were more significantly lowered in the CSO group than in the placebo group (P < 0.01, P < 0.05). The total effective rate of TCM syndrome was 95.3% in the CSO group, better than that in the placebo group (91.8%, P < 0.05). Compared with the placebo group, the serum MOT level increased and the serum SS level decreased at day 5 after operation in the CSO group (P < 0.05).

CONCLUSIONSThe plastering of CSO at Shenque (RN8) could advance the time of exhaustion and defecation, and improve patients' clinical symptoms. And patients could tolerate well.

To explore the expression potential of heterogeneous genes using the backbone of infectious bronchitis virus (IBV) Beaudette strain, the ectodomain region of the Spike gene (1,302 bp) of IBV H120 strain was amplified by RT-PCR and replaced into the corresponding location of the IBV Beaudette strain full-length cDNA. This recombinant was designated as BeauR-H120(S1). BeauR-H120(S1) was directly used as the DNA template for the transcription of viral genomic RNA in vitro. Then, the transcription product was transfected into Vero cells by electroporation. At 48 h post-transfection, the transfected Vero cells were harvested, and passaging continued. A syncytium was not observed until the recombinant virus had passed through four passages. The presence of rBeau-H120(S1) was verified by the detection of the replaced ectodomain region of the H120 Spike gene using RT-PCR. Western blot analysis of rBeau-H120 (S1)-infected Vero cell lysates demonstrated that the nucleocapsid (N) protein was expressed, which implied that rBeau-H120(S1) could propagate in Vero cells. The TCIDs0 and EIDs0 data demonstrated that the titer levels of rBeau-H120(S1) reached 10(590+/-0.22)TCID50/mL and 10(6.13+/-0.23)EID50/mL in Vero cells and 9-day-old SPF chicken embryos, respectively. Protection studies showed that the percentage of antibody-positive chickens, which were vaccinated with rBeau-H120(S1) at 7 days after hatching, rose to 90% at 21 days post-inoculation. Inoculation provided an 85% rate of immune protection against a challenge of the virulent IBV M41 strain (103EID50/chicken). This recombinant virus constructed using reverse genetic techniques could be further developed as a novel genetic engineering vaccine against infectious bronchitis.

To prepare the oral self-microemulsifying drug delivery system (SMEDDS) of GBE50, balance solubility method was used to screen emulsifier and assistant emulsifier; a pseudo-tamary phase diagram was used to prepare microemulsion; and orthogonal design was used to optimize formulation. Self-microemulsifying efficiency, dissolution, stability and pharmacokinetics of the preparation were studied. As a result, GBE50-SMEDDS of IPM, Cremophor EL, 1,2-propanediol and GBE50 could be self emulsified to form stable microemulsion with particle diameter between 20 and 50 nm when emulsifying with water. Its self-microemulsifying efficiency and dissolution are quick with good stability and it has a higher bioavailability than market existing agents Xingling particles. GBE50-SMEDDS is stable and effective.

Objective To study the effects of cooking practice education on their status of nutrient intake and blood glucose control in patients with type 2 diabetes mellitus (T2DM) over 60 years old.Methods Four-hour cooking practice education lecture was offered per month for 57 patients with T2DM over 60-year old based on balance diet and food exchange list,with features including requiring patients joining the lecture with their family members together,demonstration of raw and fresh dietary materials and cooked food,choice of food to eat by the patients themselves according to their own dietary regimen.Sixty patients with T2DM who were only educated by outpatient department of nutrition for 35 minutes were selected as control.After twelve months of education,indices such as scores of awareness of knowledge of food exchange list,status of nutrient intake and blood glucose control,and so on,were compared between the two groups to evaluate the effects of cooking practice education.Results After 12- month education,score of knowledge of food exchange list in the experiment group increased significantly,as compared to that in the control group.Intake of energy [(6304?826) kJ] and fat [(46?6) g] decreased significantly in the experimental group [(6921?860) kJ and (63?9) g,respectively],and fasting blood glucose [(7.1?0.8) mmol/L],postprandial blood glucose [(11.2?1.1) mmol/L] and glycosylated hemoglobin A1c [(6.2?0.5)%] were decreased significantly,as compared to those in the control group [(7.8?0.9) mmol/L,(12.4?1.2) mmol/L,and (6.5?0.7)%)],respectively.Conclusions Cooking practice education is effective to correctly use diet regimen and improve status of nutrient intake and control of blood glucoses for over-60-year patients with T2DM.

OBJECTIVE This study aimed to optimize polysaccharides extraction from Urena lobata L.and investigate its antioxidant activity.METHODS The mathematical model was established by re-sponse surface method (RSM) based on the results of single factor experiments, using polysaccha-rides extraction rate as response value,and using the ratio of water to material,cellulase concentra-tion,extraction temperature and time as experimental factors,which was used to screen optimum poly-saccharide extraction conditions from Urena lobata L.. Antioxidant activity of polysaccharides was stud-ied by DPPH and ·OH free radical elimination method. RESULTS The optimum conditions obtained by RSM were as follows:the cellulase level was 10.8 g·L-1,extraction time duration was 72 min,the ra-tio of water to feedstock was 7 mL·g-1,extraction temperature was 43℃,the pH value was 5.0.Under the optimal conditions, there was a difference of less than 5％ between predicted extraction rate 13.37％ and experimental extraction rate 13.32％. The polysaccharide yield was most significantly af-fected by cellulase concentration,followed by extraction time,water to material ratio and extraction tem-perature.IC50of DPPH and·OH were 1.082 g·L-1and 3.202 mg·L-1,respectively.Antioxidant activity of sample polysaccharides was weaker than those of vitamin C. CONCLUSION The polysaccharide extraction process from Urena lobata L. by cellulase enzymolysis approach was obtained, which was convenient and feasible,and extracted polysaccharides had good free radical scavenging activity.
