Surgery is the main treatment for rectal cancer, which is one of influencing factors of the patients’quality of life (QoL). Factors affecting QoL in a operation include tumor location, surgical margin, operation approach, appearance of stoma, application of laparoscopy and so forth. Still, now there are lots of arguments on how operations affecting QoL. The fol-lowing is a review about patients’QoL after different rectal surgeries, including high versus lower anterior resection, anterior versus inter sphincteric resection, transanal versus open operation, anal-sparing versus stoma operation, laparoscope versus open surgery.

0.05).Conclusion: For teeth with perforation in root canal therapy,the Propex,Raypex 5 and Root ZX electronic apex locators can detect the perforation with high accuracy.

Objective:To observe the clinical effect of electroacupuncture (EA) at four sacral points on overactive bladder syndrome.Methods:A total of 120 female patients with overactive bladder syndrome were allocated to a treatment group of 80 cases and a control group of 40 cases on a voluntary basis.The patients in the treatment group received EA at four sacral points,and the treatment was given three times a week for 6 consecutive weeks,while the patients in the control group received oral administration of M-receptor antagonist tolterodine tartrate,which was given 4 mg each time,once a day for 6 consecutive weeks.Then the symptom scores were compared between the two groups before and after treatment.Results:At the end of treatment,the symptom scores showed statistical significant differences in comparing with those before treatment in both groups (both P＜0.01);the symptom score in the treatment group was lower than that in the control group,showing a statistically significant difference (P＜0.05).Conclusion:EA at four sacral points is an effective method for overactive bladder syndrome.

0.05). Conclusion Ryanodine receptor of asthmatic guinea-pig showed hypersensitivity. Under specified condition, the characteristics of ryanodine receptor still retains in subcultured ASMCs of asthmatic guinea-pig.

Objective To investigate the changes of serum and bile from victims attacked by infantile hepatitis syndrome(IHS).Methods The constituents from 42 IHS subjects and 16 controls,including total bilirubin(TB),direct bilirubin(DB),alanine aminotransferase(ALT),glutamyltranspeptidase(?-GT),total bile acid(TBA),interleukin 6(IL-6) and tumor necrosis factor ?(TNF-? )both in bile and serum,were assayed by fully-auto chemistry analyzer and ELISA,respectively.The subjects of IHS were divided into cholestasis group and hepatitis group.Results Of IHS group,the values of serumal TB,DB,ALT,?-GT,TBA,IL-6 and TNF-? were higher than those of control(P_a

Aim The relative bioavalability of hydrochloride eperisone granule in 10 healthy volunteers was studied. Methods The time-plasma concentrations of hydrochloride eperisone granule, as test drug, and myonal, as reference drug, were determined by GC-MS, with tolperisone senuing as internal standard.The pharmacokinetic parameters of both reference and test drug were calculated and analyzed with two-one side test and confidential interval test. Results The results showed that the AUC0-8, AUC0-∞, Cmax, Tpeak, t1/2(?) and t1/2(?) were (17.9?1.3)ng?h?ml-1 and(18.6?1.6)ng?h?ml-1, (19.1?1.2)ng?h?ml-1 and (20.2?1.6)ng?h?ml-1, (5.2?0.5)ng?ml-1 and (5.4?0.5) ng?ml-1, (1.05?0.18)h and (1.08?0.23)h, (0.78? 0.13)h and ( 0.82?0.14)h,( 1.8?0.3)h and (1.8?0.3)h, respectively. The relative bioavalability of test drug was (105? 5)%. Conclusion It can be concluded that the test and reference are bioequivalented between individuals, preparations and periods.

High-speed counter-current chromatography (HSCCC) was used to high performance separate and prepare lignans from Schisandrae chinensis fructus. The solvent system is composed of n-hexane-ethyl acetate-methanol-water (9 : 1 : 5 : 5) and n-hexane-ethyl acetate-methanol-water (9 : 1 : 9 : 5), speed is at 900 r.min-1, and flow rate is at 2.0 mL.min-1. Five fractions from Schisandrae chinensis fructus extract were separated and prepared with one HSCCC process. They were identified as schisandrin, gomisin J, schisandrol B, schisantherin A and deoxyschizandrin by electrospray ionization-multiple tandem mass spectrometry (ESI-MSn), respectively. Their contents were obtained in 98.74%, 94.32%, 99.53%, 94.23% and 98.68% by ultra high performance liquid chromatography (UPLC), separately. The rapid and simple method can be applied for the preparation of lignans from Schisandrae chinensis fructus.
