To study the pharmacokinetics of ginsenosides Rg1 and its metabolites after iv and oral administration in Wistar rats, the LC-MS/MS method was selected to determine ginsenosides Rg1 and its metabolites in plasma and their pharmacokinetic parameters were calculated. After oral administration of ginsenosides Rg1 to rats, ginsenosides Rg1, Rh1, F1 and protopanaxatriol (Ppt) could be detected in plasma. Their Tmax were 0.92, 3.64, 5.17, and 7.30 h, respectively; MRT were 2.68, 5.06, 6.65, and 5.33 h, respectively; AUC(o-t), were 2 363.5, 4 185.5, 3 774.3, and 396.2 ng x mL(-1) x h, respectively. After iv administration of ginsenosides Rg1 to rats, ginsenosides Rg1, Rh1 and FI could be detected in plasma. Their T1/2betaS were 3.12, 5.87, and 6.87 h, respectively; MRTs were 1.92, 5.99, and 7.13 h, respectively; AUCo-tS were 1 454.7, 597.5, and 805.6 ng x mL(-1) x h, respectively. So, it can be concluded that after oral administration, the amounts of metabolites were higher than the prototype in vivo, and the distribution and elimination of the metabolites were relatively slow. After iv administration, the amount of prototype were higher than that of the metabolites in vivo, and the distribution and elimination of the metabolites were relatively slow.

Objective To observe the hypoglycemic effect of total flavonoids from mulberry tree leaf (MTF) on diabetic rats and the effect of MTF on disaccharidases from rats. Methods Diabetic rats were treated with MTF, and then the change of blood glucose of these rats was observed; the brush border membrane from the small intestine of rats was stripped and homogenized, which was incubated with MTF and disaccharides, and the inhibitory rate of MTF on disaccharidases was determined. Blood samples from portal and peripheral veins were separately collected at 30, 60, 120 min after maltose solution was infused into small intestine in vivo, then the difference of blood glucose concentration between portal and peripheral veins was determined. Results MTF exerted a hypoglycemic effect on diabetic rats by inhibition of disaccharidases, the inhibitory rate of sucrase, maltase and lactase was 68.0%, 47.1%, 27.8% respectively, the difference of blood glucose concentration between portal and peripheral veins was also reduced. Conclusion The hypoglycemic effect of MTF on diabetic rats is probably via the inhibitory effect on small intestine disaccharidases in rats.

Objective To investigate the prevalence of adult epileptic patients with interictal depression symptoms(IDs) and identify early predictors of IDs. Methods Adult patients with epilepsy were recruited ( n =110,45 females and 65 males) ,age between 16 and 67 years ( median 24 years). The sociodemographic and clinical factors of patients were recorded. Hamilton Depression Scale ( HAMD ) were applied to evaluate interictal symptoms of depression ( at least 72 hours after the last epileptic seizure). According to HAMD score,the epileptic patients were divided into IDs ( ≥8 ) and non-IDs(<8) groups. The sociodemographic and clinical factors were compared between the two groups to identify the prevalence and early predictors of IDs in adult epileptic patients.Results The prevalence of IDs in adult patients with epilepsy was 38.2% ,49.0% in active epilepsy and 12.1 %in seizure freedom. 30.0% ,5.5% ,and 2.7% were experiencing mild-to-moderate (HAMD score≥8),moderateto-severe ( ≥ 18 ) and severe ( ≥25 ) depression. 42 patients who met the HAMD score≥8 were classified as IDs group,and the remaining 68 patients were classified as non-IDs group. With multiple stepwise backward logistic regreasion, independent predictors of IDs were epileptic seizures ( OR = 8. 845, P = 0. 003 ); symptomatic or cryprogenic epilepsy ( OR = 3.132, P = 0. 045 ); prolonged duration of illness ( OR = 1. 106, P = 0.004 ) and employment status (OR =0. 154, P=0.001 ). There were no relationship between seizure frequency and severity of IDs ( Kruskal-Wallis test, x2 = 4.5, P = 0. 104). Conclusion IDs is a frequent psychiatric comorbidity in adult patients with epilepsy. The prevalence of IDs is higher in those with active epilepsy compared with those in seizure freedom and most of them are mild-to-moderate. Epileptic seizure, symptomatic or cryprogenic epilepsy, prolonged duration of illness and employment status are independent predictors of IDs, but seizure frequency has nothing to do with the IDs severity of patients.

Objective To assess the neuropsychological characteristics in active epileptic patients and investigate itsrisk factors. Methods Ninety adult epileptic patients included 60 active epileptic patients (two or more unprovoked seizures within 12 months) and 30 age-, sex-, education-, course of disease- and seizure type-matched seizure-free subjects (without epileptic seizure for at least 1 year) . The neuropsychological tests including trail making test,digit symbol test, verbal fluency test,digit span test and hamilton depression scale( HAMD) ,were used to detect mental and motor speed, attention, language, working memory and depression symptoms respectively. The neuropsychological tests were compared between active and seizure-free epileptic patients and identified the risk factors of neuropsychological deficits in active epileptic patients. Results Compared to seizure-free subjects, active epileptic patients had significantly worse scores in digit symbol test, verbal fluency test, digit span test ((47.45 ±18. 812) vs(56.40 ±13. 631), (25. 25 ±8. 163) vs(30.40 ±8. 414), (10. 39 ±2. 228) vs( 11. 80 ± 2.074) respectively) ; more time to accomplish the trail making test A and B((64. 35 ±31.710) vs( 45. 47 ± 16. 309) , ( 133. 18 ± 47. 331 ) vs ( 98. 00 ± 35. 003 ) respectively) ; and higher scores in depressive symptoms ((9.12 ±6.219)vs(3.77 ±3.997) ,all P<0.05). Within active epileptic group,significant predictors of neuropsychological deficits were identified in a stepwise linear regression analysis: advancing age was significantly negatively correlated with digit symbol test(β = -0. 468, P = 0. 000) , digit span test (β = -0. 439, P = 0. 000), trail making test A (β =0.365, P = 0.003) and B(β = 0.346, P=0.002) ; higher scores on depressive symptoms was significantly negatively correlated with digit symbol test (β = -0.244, P = 0.015) ; mental work,high-education level and monotherapy were positively correlated with some of the cognitive function subscales. Conclusion This study suggests that active epilepsy can have a direct adverse effect on cognition and depression symptoms. Multi-drug therapy, severity of depression symptoms, advancing age, low-education level and non-mental work are the predictors of neuropsychological impairment in active epilepsy. In addition, good seizure control even after 1 year can have a beneficial impact on cognitive and depression prognosis.

Objective To evaluate the feasibility of sentinel lymph node biopsy (SLNB) in patients with vulvar cancer. Methods Twenty-one patients with vulvar squamous cancer undergoing radical surgery admitted in Cancer Hospital of Chinese Academy of Medical Sciences from Oct.2004 to Apr.2008, were enrolled in the study. SLNB procedure was performed with blue dye alone in the first eleven patients, while the later ten patients, a combination procedure with radioactive tracer and blue dye was used to detect sentinel lymph node (SLN). All resected nodes were submitted to the pathological examination, which was considered as the gold standard to determine the efficacy of SLNB. The complications related to SLNB were also observed during the study. Results The sentinel node was identified in 20 patients (95%), included 8 cases with unilateral SLNs and 12 cases with bilateral SLN. A total of 83 SLN were identified with a mean number of 4.2 per patient (range, 1-9) or 2.6 per groin (range, 1-6). Difference between the mean number of SLN (4.4 per patient, 2.5 per groin) identified by blue dye or by combined procedure (3.9 per patient, 2.7 per groin) was not statistically significant (t=0.459,P=0.652;t=-0.421,P=0.717). Twenty patients were detected to positively superficial inguinal SLN and one of them also positively bilateral deep femoral SLN, 8 (10 groins) of them were detected positively nodal metastases. Among of eight patients, 7 (9 groins)of them were detected more than one SLN involved, while 1 of them were detected false-negative node involved. The false negative rate of was 10%(1/10), negative predictive value was 96%(22/23). No complications were attributed to the study. Conclusions SLNB procedure in vulvar cancer is feasible and safe. SLN identification appears to be highly accurate for detecting metastases in the ipsilateral inguinal lymphatic basins.

Objective To evaluate the etiology, clinicopathological characteristics, treatment and prognosis of VIN Ⅲ. Methods Thirty-five patients with VIN Ⅲ admitted in Cancer Hospital of Chinese Academy of Medical Sciences between 1993 and 2008 were analyzed retrospectively. Results All 35 patients attended to hospital with the symptoms of pruritus vulvae and lumps. Among of them, there were 28 (80%) cases whose lesions presented as multiple plaques, while 7 (20%) eases lesion were monofocal.Fifteen out of 35 eases had coexistent with human papillomavirus (HPV) related lesions, and there were the evidence of HPV in 22 patients whose pathologic sections revealed koilocytes. 34 cases (97%) except one received different types of surgical resections, including wide local resection (14/34), simple vulvectomy (16/34) and simple vulvectomy plus perianal skin resection (4/34), while there two cases shown positive cut-edges and one of them received radiotherapy postoperatively. Four out of the 34 cases recurred locally in 2, 4, 6 and 22 months and received surgical treatment again or laser therapy, respectively. The median follow-up period was 66 months ( range 1-166), and none of them were died of the disease itself except one case died of the concurrent cervical cancer. Among 26 cases received the investigation of the quality of life,there were nine cases (35%) suffered from sexual dysfunction after the operation, and one of them received vulvoplasty. Conclusions VIN Ⅲ has good prognosis. The development of VIN Ⅲ may be related to the infection of HPV, because most of them concurrent with HPV diseases. Its primary treatment is surgical resection, while affecting on the quality of life.
