Objective To observe the traditional Chinese medicine (TCM) and umbilical treatment on diarrhea-predominant irritable bowel syndrome(IBS-D)with mental disorders. Methods Thirty-seven cases with IBS-D were randomized into a treatment group(33 cases) and a control group(31 cases). The treatment group was given Shugan-Jianpi TCM decoction and pepper umbilical dressing. The control group was given Pinaverium Bromide Tablets and Flupentixol and Melitracen tablets. After having been treated for 4 weeks, Hamilton Anxiety Scale(HAMA), Hamilton Depression Scale(HAMD), IBS Symptom Severity Scale(IBS-SSS), IBS quality of life questionnaire (IBS-QOL) were determined. Results After the treatment, HAMD, HAMA, IBS-SSS in the treatment group and the control group all significantly decreased (the treatment group t=14.280, 13.530, 18.847,the control group t=11.514, 9.424, 13.829, P<0.01), and IBS-QOL increased markedly(t=-16.848, -11.712, P<0.01). Compared with HAMA, IBS-SSS and IBS-QOL in treatment group, the control group showed statistical difference(t=-3.183, -2.549, 3.904, P<0.01 or 0.05). The total effective rate of the treatment group was 94%higher than 75%of the control group(χ2=4.727, P<0.05). Conclusion Shugan-Jianpi TCM decoction and pepper umbilical dressing can improve the clinical symptoms and psychological symptoms and improve the quality of life of IBS-D patients.

Pterocypsela is a very important traditional Chinese medicine from the tribe Cichorieae of Asteraceae. Mitotic chromosome numbers and karyotypes are reported for P. formosana and P. elata from Hunan and Hubei province, China. The former is new and the latter provide confirmation of previous reference. All P. taxa are diploidy with 2n = 18 and their basic number is tentatively suggested as x = 9. Karyotype of Pterocypsela is 2A and P. formosana with a karyotype formula of 2n = 2x = 18 = 4m + 14sm, and 2n = 2x = 18 = 2m + 8sm +8st for P. elata. It is the first time to report the AI value for Pterocypsela in this paper. Cytological data of chromosomal numbers and karyotypes were used to discuss the close relationships of the Pterocypsela genus and the taxonomy of the medicinal plants.

OBJECTIVETo establish the theories and methods to determine apparent solubility paraneters of multiple components for the Chinese materia medica (CMM) with HPLC fingerprint.

METHODThe mathematical functional expresses to determine the apparent solubility parameters for multiple constituents were established according to total quantum geometrical average retention time (TQGART) for HPLC fingerprint that characterized the entirety tendencies for all-over chromatographic peaks, validated by the aloe-emodin's solubility parameters which had been determined. The HPLC for the aloe-emodin's solubility parameters were carried out with an Alltech Apollo C18 as column, Acetone: Water as mobile phase, gradient elution,flow rate as 1.0 mL x min(-1), the detection wave-length as 430 nm and the temperature as 30 degrees C.

RESULTThe mathematical functional model between the TQGART of HPLC chromatographic fingerprint and the total quantum apparent solubility parameters was established and used to determine the aloe-emodin's mixture solubility parameter as 36.12 J(1/2) x cm(-3/2), nearly equal to 35.57, 36.07 J(1/2) x cm(-3/2) calculated by ration of peak area ratios and molecular fraction, respectively.

CONCLUSIONThe TQGART of HPLC fingerprint can be used to determine simultaneously the apparent or single intrinsic solubility parameters for total quantum or intrinsic solubility parameters for single in multiple constitute systems, by which theoretical and technologic platform to study the compatibility rule and dosage form reform of the single CMM will be established.

Objective:To study the effect of interleukin-11(IL-11),ciliary neurotropic factor (CNTF) and transforming growth factor-β (TGF-β) on the hGH gene promoter activity in rat pituitary MtT/S cells and the interaction with pituitary-specific transcription factor Pit-1.Methods:Stable transformed MtT/S cell line which contains hGH gene promoter -484-30 bp and luciferase reporter gene firstly established,then the concentration of GH in the medium and lysate of MtT/S cells and luciferase activities in MtT/S cells were measured after treatment these cells with the above cytokines,the effects of cytokines on secretion and synthesis of GH,and the promoter activity of the hGH gene were observed.Results:The results showed that IL-11(20 nmol/L),CNTF(10 nmol/L) and TGF-β(5 nmol/L) regulated secretion and synthesis of GH,and the luciferase expression in stable transformed MtT/S cells.IL-11 and CNTF had the stimulatory effect,whereas TGF-β had the inhibitory effect.Neither overexpression of Pit-1 nor inhibiting Pit-1 expression affected the regulatory role of these cytokines.Conclusion:IL-11,CNTF and TGF-β regulate the GH production in pituitary MtT/S cell line by regulating the hGH gene promoter activity.Pit-1 may not be involved in these actions.

Stromal preadipocytes from human omental adipose tissues were isolated with enzyme-digesting method,and cultured for inducing differentiation.Preadipocyte factor-1 was abundant during preadipoeyte stage,whereas lipoprotein lipase and PPARγ2 mRNA were rapidly up-regulated at early stage of differentiation and CCAAT/enhancer binding protein expression was increased rather late.In addition,resistin expression and secretion was primarily detectable in preadipocytes,leptin was gradually increased during adipogenesis,whereas adiponectin appeared specifically in mature adipocytes.Insulin-like growth factor-Ⅰ secretion was remarkably detected in both preadipocytes and mature adipocytes.

Objective To identify the changes of body composition with acromegaly before and after pituitary adeno-ma surgery,and to evaluate the relationship between these changes and serum growth hormone(GH),insulin-like growth factor-1(IGF-1).Methods Serum GH with OGTY,IGF-1 levels,BMI,fat percentage,FFM and total body water(TBW) in patients were measured in active and relieved period of the disease.Results The BMI and FFM with active acromegalic males were significantly higher,but fat percentage was significantly lower than that of healthy males.After the disease was relieved by surgery,serum GH and IGF-1 concentrations of patients were sig-nificantly reduced to normal level,but their BMI was still significantly higher,the fat percentage increased and the FFM decreased was correlated with serum nadin GH and IGF-1 levels.The BMI and FFM with active acromegalic females were significantly higher than healthy females,but the fat percentage had not significant change after sur-gery,and FFM decrease was correlated with reduced serum GH level.The fat percentage did not change signifi-cantly.Conclusion There was significant change of body composition with acromagely before and after treatment,and a relationship between these changes and serum GH and IGF-1 levels was identified.
