Objective To set up a RP-HPLC method for determining gastrodin and ferulic acid in drug delivery system of Dachuanxiong simultaneously. Methods ODS-2 Hypersil column was used with methanol-1% glacial acetic acid as solution gradient elution. The flow rate was 1 mL/min and column temperature was 25 ℃. The wavelength of detector of gastrodin was 270 nm, and ferulic acid was 322 nm. Results Gastrodin and ferulic acid can be separated well with other components within 40 minutes. The linear range of gastrodin was 0.092～1.840 ?g (r =1.000 0), and ferulic acid was 0.122～2.440 ?g (r =1.000 0). The average recovery rate of gastrodin was 99.50% with RSD=1.23% (n =5), and ferulic acid was 101.5% with RSD=1.52% (n=5). Conclusion The method is simple, rapid, accurate and reliable, and can be used for determining gastrodin and ferulic acid in drug delivery system of Dachuanxiong simultaneously.

Objective To investigate the feasibility of kidney sparing operation in the surgical treatment of calculous pyonephrosis. Methods 31 cases of calculous pyonephrosis were treated by nephrolithotomy or ureterolithotomynephropyelostomy with a double J catheter stent in the ureter.23 cases have been followed up and evaluate. Results The renal function returned to some extent in 78.3%(18/23).However,renal atrophy was observed in 21.7%(5/23) one year after and stone recurrence in 13%(3/23). Conclusions Calculous pyonephrosis of short course on reliving the obstruction would cause the return of renal blood circulation and renal function in near 80.0% of the cases.Thickness of the remaining renal cortex might not be the sole parameter to keep the kidney or not.To save the kidney in calculous pyonephrosis of short course might be feasible.

A study on the ideal method for cryopreserving human fetal islet tissues was carried out. The viability and the secretory function of fetal islets cryopreserved with 1.0,1.5,and 2.0 mol/L DMSO and with balancing for 30 and 60 minutes under room temperature and 4℃ as well as the influence of different cooling rates were compared. The results of the study showed that the viability of islets cryopreserved with slow cooling rate at 0.3℃/min, was the best and the insulin content of the media and the amount of insulin secretion of the insulin releasing test were significantly higher than those of the control group.In addition,morphologic examination with HE and immunocytochemical staining showed that the morphology of the islets cryopreserved with 1.5 mol/L DMSO,balancing under 4℃ for 60 minutes and slow cooling rate was much better,i.e.the acinar cells appeared to be degenerated and necrosed,clusters of islets with insulin-positive cells and the ductule-like cells were clearly visible.

Objective To compare the effects of different spleen-strengthening recipes on water-electrolyte metabolism and water transport in rat model of spleen-deficiency syndrome. Methods The male Wistar rats were randomly assigned into the normal group and spleen-deficiency model group. The rat model of spleen-deficiency was established by overstrain plus disordered diet method. On the 15th modeling day, the model rats were randomly assigned into model group , Buzhong Yiqi Tang(BYT) group, Si Junzi Tang(SJT) group, Shenling Baizhu San(SBS) group, and the rats except for the model group were treated with gastric gavage of the corresponding medicine in the dosage of 4.05 g·kg-1·d-1. Rats of normal group and model group were given equal volume of normal saline. The medication lasted for 14 days. On the 29th experimental day, we detected serum Na+ and K+, plasma antidiuretic hormone(ADH) and aldosterone(ALD), aquaporin 3(AQP3) in the small intestine and colon, and renal AQP2. Results Compared with the normal group, plasma ADH and ALD levels, serum Na+ level, renal AQP2 content in the model rats were increased significantly, serum K+ and AQP3 content of small intestine and colon mucosa was decreased significantly(P<0.01). Compared with the model group, plasma ADH and ALD levels, serum Na+ level, renal AQP2 content in the three medication groups were decreased significantly, serum K+level and AQP3 in the small intestine and descending colon mucosa was increased significantly(P<0.05 or P<0.01). Of the three medication groups, SBS group had lower ADH, ALD, Na+levels, and higher serum K+level and AQP3 in the small intestine and descending colon mucosa than BYT group and SJT group(P<0.01); SBS group and BYT group had lower renal AQP2 than SJT group(P<0.05 or P<0.01). Conclusion Rat model with spleen-deficiency syndrome has disordered water-electrolyte metabolism and abnormal water transport. The spleen-strengthening recipes, which have the actions of strengthening spleen, strengthening spleen to drain dampness, strengthening spleen to elevate yang, can improve the disorder of water metabolism to some degrees, and SBS has the best effect.

Oral sustained- and controlled-release drug delivery systems of traditional Chinese medicine (TCM) are a research hotspot in the development of drug-delivery systems for TCM. The quality evaluation system is an important guarantee for the safety and efficiency of these drug-delivery systems. In this paper the methods to construct such quality evaluation system were discussed.

The drug release characteristics ofDa Chuanxiong Fang multiunit drug delivery system (DCXFMDDS) in vivo and in vitro were evaluated. Ferulic acid (FA) and senkyunolide I (SI) were used as marker components, which were two of the effective components of Da Chuanxiong Fang. And their contents were determined by HPLC. Drug release characteristics in vitro of DCXFMDDS and Da Chuanxiong pills and pharmacokinetics characteristics of DCXFMDDS and Da Chuanxiong Fang active fraction (DCXFAF) in rats were compared. It was obvious that FA released from the DCXFMDDS in a sustained fashion but SI in a fast fashion both in vitro and in vivo. The releasing process and the releasing mechanism of FA and SI from DCXFMDDS were different, but the AUC value indicated that compared with DCXFAF the extent of absorption of FA and SI from DCXFMDDS was increased. Though from the same multiunit drug delivery system, FA an SI had different drug release characteristics both in vitro and in vivo, and that may be one of the reason why DCXFMDDS has the good properties such as rapid and long-lasting effect and high efficiency.

The effects of vasectomy on the reproductive organs in various species are controversial. This study investigated the morphological change and apoptosis of the testis, epididymis, and vas deferens in beagle dogs 12 months after vasectomy. The male beagles were divided into two groups: vasectomized and sham-operated groups (n=5 in each). Histopathological, ultrastructural, and TUNEL evaluation of the changes in the testis, epididymis, and ductus deferens of each animal were conducted 12 months after surgery. The mean lumen diameter, cellular thickness, mean interstitial distance, and lumen area fraction of each seminiferous tubule and ductus epididymis were measured by stereological analysis. The results showed that, compared with the sham-operated group, the seminiferous tubular epithelial cells of the testes in the vasectomized group were disorderly arranged and scattered. Significant atrophy and apoptosis were found in the endothelial cells, and a range of ultrastructural variations were observed in the cells of testes, epididymis, and vas deferens in vasectomized group. It was concluded that complete obstruction of the vas deferens as a traditional contraception method is not absolutely safe in terms of the reversal of fertility in the long run. Techniques of relieving the inner pressure in the vas deferens while maintaining the efficacy of male contraception need to be explored.

Objective To evaluate the efficacy of puerarin for prevention of brain injury in the patients undergoing open heart surgery under cardiopulmonary bypass (CPB).Methods Thirty ASA physical status Ⅲ patients of both sexes,aged 50-64 yr,weighing 50-75 kg,scheduled for elective cardiac valve replacement under general anesthesia,were randomly divided into 2 groups (n =15 each) using a random number table:control group(group C) and puerarin group (group P).Puerarin 400 mg was infused intravenously over 30 min immediately at skin incision in group P and the equal volume of 5％ glucose-sodium chloride injection was given in group C.Before induction of anesthesia (T0),at 30 min of CPB (T1),immediately after aortic unclamping (T2),and at 6,12 and 24 h after termination of CPB (T3.5),blood samples were collected from the jugular venous bulb for determination of the plasma concentration of neuron-specific enolase (NSE) and S-100 β protein.P300 eventrelated potential latency and amplitude were determined and cognitive function was assessed by Mini-Mental State Examination (MMSE) score at 1 day before surgery and 7 days after surgery.The patients were diagnosed as having post-operative cognitive dysfunction when MMSE score before surgery-MMSE score after surgery ≥ 2,or when M MSE score≤ 24.Results Compared with group C,the concentrations of plasma NSE and S-100 β protein were significantly decreased at T15,and P300 event-related potential latency was shortened,P300 event-related potential amplitude was increased,and the incidence of postoperative cognitive dysfunction was decreased at 7 days after operation in group P.Conclusion Puerarin can prevent the brain injury in the patients undergoing open heart surgery under CPB.
