Ginseng is a typical adaptogen which has resistance to various stresses. This effect is related to the hypothalamic-pituitary-adrenal (HPA) axis. As the main active ingredients, saponin has the similar structure to steroids. The regulation characteristics of ginseng saponin on the HPA axis are narrated from the aspects of total saponin and saponin monomers in this paper after the introduction of adaptation definition and HPA axis regulation mechanisms. Pharmacological effects of ginseng saponin and the regulation effect of HPA axis are summarized finally.

Objective: To investigate the influence of repeated infiltrating on the microstucture of In-Ceram alumina substrate. Methods:6 disks of aluminum oxide with the height of 3 mm and diameter of 12 mm were perpared and infiltrated with infiltrating glass for 0~5 times for each disk respectively.The fractured surfaces of the samples were observed by scanning elctron microscope. Results:After sintering,a net -shaped porous coping of alumina was formed. The glass infiltration resulted in a dense ceramic mass. The porous coping matrix was infiltrated with low-viscosity glass in void.3-time-infiltration resulted in the best results. Conclusion: With repeated infiltrating firing,the micro-stucture of In-Ceram alumina substrate may become a dense mass.

Objective To investigate the clinic effect of trans-artery intrahepatic transplantation of porcine islet in type 1 diabetic patients. Methods Four patients with type 1 diabetes were perfused newborn porcine islets through the hepatic artery.Fasting blood glucose(FBS), postprandial blood glucose (PBS), HBA1,dose of insulin and function of liver and kidney were measured before and after the transplantation.Results The levels of FBS,PBS and HBA1 were 7 4~13 5mmol/L,7 8~18 6mmol/L and 7 8~12 0mmol/L respectively before the transplantation. During one and half years after transplantation, the levels of FBS,PBS and HBA1 were 3 3~7 1mmol/L,6 0~8 8mmol/L and 6 4~7 6mmol/L respectively with notably reduced dosage of insulin(32~58%).The function of liver and kidney of the patients remained normal.Conclusions Trans-artery intrahepatic transplantation of porcine islet is effective and safe for type 1diabetic treatment.

Objective To evaluate the clinical results of expansive cervical laminoplasty by anterior and posterior cervical decompression in the treatment of Cervical Spondylosis Myelopathy with developmental cervical stenosis.Methods Retrospective analyze 32 patients of cervical spondylosis myelopathy treated with expansive cervical laminoplasty by anterior and posterior cervical decompression from Mar 1995 to Aug 2000 years, there were 21 males and 11 females, developmental cervical stenosis (DCS) with cervical intervertebral disc protrusion in 25 cases, with the ossification of cervical posterior longitudinal ligament (OPLL) in 7 cases. Neural functionality (JOA Scoring System), cervical axial symptoms, and pre-and post-surgery dynamic cervical spine lateral x-ray films and cervical vertebra MRI were evaluated. Results 32 cases had been followed up for an average of 24.3 months, with an average age 58.9 years (range 38-72). The average rate of improvement of the third and sixth in month postoperative,the first and third postoperative year was 58.1%,65.9%,69.1% and 68.4% respectively;the excellent and good was 71.9%,81.3%,78.1%,77.3% respectivery. Cervical axial symptoms were reduced. Instability of the cervical spine were not found and decompression was confirmed on MRI. Conclusion Expansive cervical laminoplasty by anterior and posterior cervical decompression in the treatement of cervical spondylosis myelopathy with developmental cervical stenosis have good efficacy and it is a stable operative method.

Objective To study the physiology of sleeping in a swine model with obstructive sleep apnea syndrome (OSAS) reproduced by high altitude and hypoxia. Methods Twelve male minipigs were randomly assigned to 2 groups, named A and B. The pigs of Group A were placed in Room 1, which was a double-room altitude chamber, and the pressure in it was adjusted to 53.9 kPa with an oxygen concentration of 10.0%~11.2%. The pigs of Group B were kept in Room 2 with altitude of sea level and oxygen concentration of 21%. All the animals were kept in their respective rooms for 6 hours per day and for 22 consecutive days. On the 23rd day sleeping was monitored, at the same time the movements of chest and abdomen, respiratory airflow, heart rate, and pulse oxygen saturation (SpO_2) were recorded. Apnea/Hypopnea Index (AHI), Hypopnea Index (HI), and average SpO_2 were derived from analysis of the data of sleeping monitoring. Pigs were sacrificed after the experiment, and pharyngeal tissue was harvested for pathological examination. Results The AHI (16.1?8.3 vs 2.3?1.6), HI (4.3?3.1 vs 1.3?1.0), SpO_2 (86.7?3.6 vs 94.5?1.8) of pigs of group A showed were have significant differences compared with that of the control (P

10.Zweymüller spiral acetabular prosthesis for treating developmental dysplasia of the hip in adults
Chinese Journal of Tissue Engineering Research 2015;(39):6274-6280
BACKGROUND:Spiral acetabular prosthesis has good stability during total hip arthroplasty.
OBJECTIVE:To observe the early therapeutic effect of Zweymüler spiral acetabular prosthesis in total hip arthroplasty for patients with developmental dysplasia of the hip.
METHODS:Totaly 38 patients (48 hips) with developmental dysplasia of the hip received total hip arthroplasty with Zweymüler spiral acetabular prosthesis from January 2011 to June 2013 were selected. The clinical effect was observed after the operation.
RESULTS AND CONCLUSION: A total of 38 patients were folowed up for 21-46 months (averagely 42.3 months). One case suffered from deep venous thrombosis. Harris scores and Charnely scores apparently increased after surgery compared with that before surgery. The mean length of the osteotomy was 2.42±0.48 cm, and the mean extended length of the affected limb was 4.58±1.15 cm. X-ray films showed that there was no disunion of the osteotomy, no subsidence and loosening of prosthesis. The position of the acetabulum was suitable. The healing time of bone graft was 3-11 months (averagely 5.3 months). The coverage of the acetabular component was 92.5%, with a good initial stability, and the excelent rate of the operation was 90%. The satisfaction rate of patients was 84%. These results indicate that the Zweymüler spiral acetabular prosthesis has the advantages of reasonable design, good initial stability, low loosening rate and high satisfaction degree. However, the number of cases of this study was relatively smal, the folow-up time was short, and only the short-term effect was evaluated. Thus, the midterm and long-term effects need to be observed by the folow-up evaluation.
