This study was carried out to determine the inhibitory effects of phytate on the bioavalaibility of calcium (Ca), ferum (Fe) dan zink (Zn) in selected soy-based products. Phytate exerts its inhibitory effects on the absorption of minerals such as Ca, Fe and Zn by forming insoluble and undigestible complexes. The inhibitory effect of phytate on the bioavailability of minerals like Ca, Fe and Zn was estimated by measuring their molar ratios. Phytate content was determined by using anion-exchange method while mineral contents were determined by Atomic Absorption Spectrophotometer (AAS). Soybased products were bought from the night markets and food stall located at Cheras and Sri Rampai, Kuala Lumpur. Each samples from both location was analysed in duplicates. Results from this study showed that soy cake and all dishes containing tempe did not contain phytate content. This may due to the presence of R. oligosporus that produces phytase and hydrolysed the phytate content during the fermentation process of tempe. There were fi ve food samples that have a phytate/ Ca molar ratio > 0.24, ten food samples with a phytate/ Fe molar ratio > 1, eight food samples have a phytate/ Zn molar ratio >15 and one food sample has a [phytate x Ca]/ Zn molar ratio > 200. The result of molar ratio phytate/ mineral in this study estimated the low bioavailability of Ca, Fe and Zn. In conclusion, soy cake and all dishes containing tempe contained high bioavailability of minerals, while tau-hoo pok contained low bioavailability of minerals

Objective To evaluate the short-term efficacy of Perigee system in the treatment of anterior pelvic organ prolapse. Methods From October 2012 to September 2014, 59 patients with pelvic organ prolapse, pelvic organ prolapse quantitation system (POP-Q) were diagnosed as anterior pelvic organ prolapse Ⅲ degree and above were performed Perigee anterior pelvic floor reconstruction, while some patients combined with sacrospinous ligament suspension, posterior wall repair or posterior pelvic reconstruction surgery for pelvic prolapses. Pelvic floor distress inventory-short form 20 (PFDI-20), pelvic organ prolapse-urinary incontinence sexual questionnaire-12 (PISQ-12) were evaluated, and postoperative POP-Q were used to analyze the changes of the indexes and postoperative complications. Results In 59 patients, the average operation time was (99±29) minutes, the average intraoperative blood loss was (119± 92) ml. The median postoperative follow-up time of 59 cases was 17.5 months (range:8-30 months), median follow-up time of subjuctive symptoms was 21.2 months (range:11-34 months), the total score of PFDI-20 was compared with the preoperative, and the difference was statistically significant (5.6 versus 27.8, P<0.01). It was statistically significant of PISQ-12 score before and after surgery (34±3 versus 36±4, P<0.05). Short-term anatomical cure rate was 98%(58/59), 1 cases (2%, 1/59) in recurrence, 2 cases (3%, 2/59) of erosion. Conclusion This results show that the Perigee system is effective and reliable in the treatment of anterior pelvic organ prolapse.

Objective:To summarize the clinical features, genetic testing and treatment efficacy of 6 children with Dent disease.Methods:Six children diagnosed with Dent disease in Guangzhou Women and Children′s Medical Center from January 2014 to March 2019 were enrolled.Their medical history, clinical manifestations, laboratory results, genetic test results, and proteinuria level, calciuria level and renal function after medication were measured.Results:All patients were male, with the onset age ranged from 1 to 9 years old.They were followed up for 6 months to 4 years.All the children had low molecular weight proteinuria.Urine protein electrophoresis showed that the ratio of low molecular weight proteinuria in only 2 cases was more than 50%.Renal biopsy suggested that all cases were combined with glomerular lesions.Five cases had hypercalciuria.Under the microscope, there were 5 cases of hematuria.Two case had rickets, and there was no renal calcium deposition and hypophosphatemia.Five cases were detected with CLCN5 mutations, of which p. C160Yfs*49 and p. G523D were first reported.One case had an OCRL1 mutation.Patients were treated with Hydrochlorothiazide and angiotensin converting enzyme inhibitor (ACEI). The 24 h urinary calcium level after treatment was lower than that before treatment [0.40 (0.24, 0.43) mmol/kg vs.0.12 (0.11, 0.14) mmol/kg, U=2.00, P<0.01]. However, there was no significant decrease in the 24 h-urinary protein level before and after treatment [77.09 (62.41, 88.01) mg/kg vs.80.33 (66.03, 92.52) mg/kg, U=12.00, P>0.05]. Conclusions:Dent disease is mainly characterized by low molecular weight proteinuria, and some patients may not be associated with hypercalciuria.Gene tests help to identify the disease type.ACEI and Hydrochlorothiazide can reduce the urinary calcium level, but cannot improve the level of urinary protein.

Objective To investigate the effect of triptolide on the proliferation and apoptosis of human epidermal squamous cell carcinoma cell line A431 in vitro. Methods Human epidermal squamous cell carcinoma cell line A431 was cultured. After the treatment with triptolide, the inhibi-tion of cellular growth was determined by measuring MTT dye absorption of the living cells. Light mi-croscope showed morphological changes. The cell cycle and apoptosis rate were assessed by flow cy-tometry. Results Triptolide could significantly inhibit the proliferation of A431 cells in a dose- and time-dependent manner. Triptolide could also cause cell morphological changes ( the number of float-ing cells and nuclear pyknosis increase), induce cell apoptosis, and change the distribution of cell cycle phase in A431 cells. Compared with the control group, the G0/G1 phase A431 cell rate in-creased and the rate of S phase cell decreased in TP-treated group. Cell cycles were obviously inhibi-ted by triptolide in G0/G1 phase (both P<0.05). Conclusion TP could play an anti-tumor role by effectively inducing cell apoptosis and inhibiting the proliferation of A431 cells.

To investigate me material basis of Mahuang Fuzi Xixin decoction (MFXD) for anti-inflammation and immune-suppression based on the combined method of serum chemical and serum pharmacological. The LC-MS/MS fingerprints of MFXD, drug-containing serum and blank serum were compared to define the components in plasma. Histamine, β-hexosaminidase released from RBL-2H3 cell infulenced by drug-containing serum at different time points were measured by ELISA. The effect of drug-containing serum on lipopolysaccharide-induced splenocyte proliferation at different time points were determined by MTT. A correlation analysis was made on components of MFXD and pharmacological indexes based the stepwise regression method. After the intragastrical administration with MFXD, 32 components were discovered in rat serum, including 27 prototype components (10 from Mahuang, 13 from Fuzi and four from Xixin) and five unknown components. Compared with blank serum, drug-containing serum could reduce the release of histamine from RBL-2H3 induced by antigen at different time points (P < 0.05); except the 4-hour drug-containing serum, all of the remaining drug-containing serums could inhibit the RBL-2H3 mastocyte degranulation induced by antigen at different time points (P < 0.05). Drug-containing serum could significantly lipopolysaccharide-induced mouse splenocyte proliferation at 15 and 30 min (P < 0.05). A regression analysis was made on the chemical data of components absorbed into blood and pharmacological indexes, i. e. release rate of histamine, release rate of β-hexosaminidase and inhibition rate of splenocyte. This suggested the close correlations among methyl pseudo-ephedrine, pseudoephedrine and histamine released from RBL-2H3 induced by antigen; pseudoephedrine, hypaconine, methyl pseudoephedrine and β-hexosaminidase released from RBL-2H3 induced by antigen; as well as benzoyl hypaconine, benzoylaconine, 14-benzoyl-10-OH-mesaconine, mesaconine and lipopolysaccharide-induced mouse splenocyte proliferation. Methylpseudoephedrine, pseudoephedrine, benzoyl hypaconine, benzoylaconine and mesaconine may be part of material basis of MFXD on anti-inflammation and immune suppression.
