Notoginseng Radix et Rhizoma (Sanqi), the underground part of Panax notoginseng (Burk.) F. H. Chen (Araliaceae) is commonly used in Chinese medicine for treatment of haemorrhage, haemostasis, swelling, etc. The aerial part including leaves, flowers and fruits are also applied for similar functions. Triterpenoid saponins are considered to be responsible for the biological activities of Sanqi. Up to date, more than 100 saponins have been isolated from theroots, rhizomes, leaves, flowers and fruits of P. notoginseng. The reported saponins can be classified into protopanaxadiol (PPD), protopanaxatriol (PPT), C17 side-chain varied and other types, according to the skeletons of the aglycons. The present review summarizes the saponins isolated from P. notoginseng and their distribution in different medicinal organs, as well as the pharmacological actions on cardiovascular system.

AIM: To evaluate the efficacy of vitrectomy and pan-retinal photocoagulation followed with Ahmed implantation in management of neovascular glaucoma ( NVG) retrospectively.
METHODS: Vitrectomy combined with pan retinal photocoagulation and Ahmed implantation was performed on 15 cases ( 15 eyes ) with NVG. All patients were followed up for 12 ~ 36mo. The change of intraocular pressure (IOP), visual acuity, neovascularization of iris, complications were observed.
RESULTS: The visual acuity of 10 eyes was improved postoperative. IOP of postoperative 1, 6 and 12mo were decreased significantly compared with preoperative ( P<0.01 ) . Neovascularization of iris was reduced dramatically. No serious complications occurred.
CONCLUSION: Vitrectomy combined with pan retinal photocoagulation followed Ahmed implantation can manage NVG effectively.

Purpose:To investigate the prevention and treatment protocol for Af after resection of esophageal and car- dia carcinoma.Methods:Analyses for clinical materials of 1527 patients underwent resection for esophageal and cardiac carcinoma.Results:There were Af 23 cases.Age older than 60 years,abnormal ECG or/and pulmonary function before operation,gastro-esophageal anastomosis above the aortic arch and histological staging Ⅲ～Ⅳ were risk factors for AF.Fa- tal AF was rarely seen.In our 23 cases after treatment in time AF disappeared.Conclusions:Further recognition for post- operative AF and management of perioperative period complication,may reduce the danger of postoperative AF.

Objective To investigate the factors related to the heating effect by transarterial catheter hyperthermic infusion with the evaluation of the feasibility in controlling the tumor temperature.Methods Infusing 55-68℃ liquid at the speed of 10-40 ml/min through 6F,5F or 3F catheter with different length respectively under the similar clinical condition.The liquid temperature at the terminal exit of the catheter was measured with a digital thermometer.The factors related to the liquid temperature at the exit of the catheter were analyzed by multiple regression analysis. Results The infusion temperature,rate and the catheter length were the main related factors to the liquid temperature at the exit of the catheter as the condition similar in clinical use.When 60-65℃ liquid was infused at the rate of 20-40 ml/min through 5F catheter with length of 80 cm,the mean and 95% confidencial interval of the liquid temperature at the chetheter exit were(47.55?0.44)℃ and 44.61-48.49℃ respectively.Conclusions The liquid temperature at the exit of infusion catheter can be regulated and controlled through adjusting the liquid perfusion temperature and speed.

Objective:To compare the expression and biological activity of glucosyl transferases (GTFs)of Streptococcus mutans (S.mutans)under normal outside environment between high temperature requirment serine proteinase A(HtrA)-deficient strains and high virulent strains isolated from children with high cario-susceptibility.Methods:The HtrA-deficient strains and high virulent strains of S.mutans were obtained by preliminary study.The strains were reanimated and incubated in BHI medium to exponential phase at tenth hour.The expression of gtfB,gtfC and gtfD were detected by real-time RT-PCR.The biological activity of the GTFs were detected by entong sulfuric acid method and Western Blot.Results:The expression of gtfs and GTFs in the HtrA-deficient strains was higher than those of high virulent strains,but the biological activity of the GTFs was lower.Conclusion:The HtrA gene plays an important regulatory role in the process of the GTFs expression of S.mutans isolated from children with high cario-susceptibility.

AIM: To explore the effect of collagen and C-erbB-2 protein on the adhesion and the proliferation in hepatocellular carcinoma cells.METHODS: Hepatocellular carcinoma cell line(HepG-2) identified to positive for C-erbB-2 gene was used to study the adhesion and the growth feature by the action of rat tail collagen and C-erbB-2 antibody.RESULTS: The action of rat tail collagen to potentiated the adhesion in HepG-2 cells was significantly but no proliferation effect was observed. C-erbB-2 antibody inhibited the adhesion and proliferation of HepG-2 cells and also abolished the potentiated effect of rat tail collagen on the adhesion in HepG-2 cells.CONCLUSIONS: The signaling transduction mediated by C-erbB-2 protein was correlated to the adhesion and the proliferation of HepG-2. The blockage of C-erbB-2 gene signal transduction may be a strategic target to the treatment of liver cancer in the future.

Objective To explore the perioperative experiences of congenital heart disease in infants.Methods From Jan.2000 to Aug.2006,109 patients with congenital heart disease were operated in our department,their clinical data were retrospectively collected and analyzed.The patients′ age ranged from 31 days to 3 years old (13.6 months).The body weight ranged from 2.1 to 16 kg (8.6 kg).Ninety-three patients were operated under hypothermic anaesthesia with cardiopulmonary bypass(CPB).Sixteen patients underwent deep thermal and low flow CPB.Ultrafiltration was used in 62 patients.Results There were 8 deaths and the operative mortality was 7.3%,4 cases caused by low output syndromeclos(LOS),3 cases caused by pulmonary hypertension and 1 case caused by lung intection.The morbidity was in 25 cases(22.9%),the main complications were LOS in 6 patients and respiratory complications in 18 patients,hydropericardium in 1 case,respectively.Conclusion To improve the operative and CPB technique,and to improve the skills of the postoperative managements of LOS and respiratory complications are the main points in the success of the cardiac operation in infants.

OBJECTIVETo observe the effect of Qianliean Pill (QP) on inflammatory factors such as IL-1β, IL-10, and tumor necrosis factor α (TNF-α) in chronic nonbacterial prostatitis (CNP) model rats, and to explore its therapeutic mechanism.

METHODSCNP rat model was established by castration and estradiol benzoate injection. Totally 50 rats were randomly divided into 5 groups, i.e., the model group, the positive medicine group, the high dose QP group, the medium dose QP group, and the low dose QP group, 10 in each group. Besides, 10 normal rats were recruited as a normal control group. Since the 8th day of castration, Pulean Tablet (PT) at 10. 80 g/kg was administered to rats in the positive medicine group by gastrogavage. QP at 11.00, 5.50, and 2.75 g/kg was administered to rats in high, medium, and low dose QP groups by gastrogavage. Distilled water at 2 mL/100 g was administered to rats in the model group and the normal control group by gastrogavage, once daily for 30 successive days. After 30 days of medication all rats were sacrificed and their prostate tissues were extracted. The prostatic index was calculated. Pathological changes of rat prostate were observed under light microscope. Meanwhile, levels of IL-1β, IL-10, and TNF-α were detected using enzyme linked immunosorbent assay.

RESULTSCompared with the normal control group, the prostate index obviously decreased, levels of IL-1β, TNF-α, and IL-10 in the prostate tissue significantly increased in the model group (P < 0.01). Compared with the model group, the prostate index obviously decreased in high and medium dose QP groups, and the positive medicine group (P < 0.01); levels of IL-1β, TNF-α, and IL-10 obviously decreased in each QP group and the positive medicine group (P < 0.01). Compared with the positive medicine group, the TNF-α level decreased more obviously in the high dose QP group (P < 0.05). Compared with the normal control group, inflammatory reactions occurred obviously in rats' prostate of the model group. Compared with the model group, inflammatory reactions were milder in rats' prostate of each QP group and the positive medicine group, and their degrees were improved to some extent.

CONCLUSIONQP could treat CNP, which might be achieved by regulating local immune state of the prostate, relieving inflammatory reactions of the prostate, and lowering levels of IL-β, TNF-α, and IL-10 in the prostate tissue.
