Journal of Integrative Medicine 2008;6(7):704-10
OBJECTIVE: To study the absorption and transport of pachymic acid (PA) isolated from the sclerotium of Poria cocos (Schw.) Wolf. in human intestinal epithelium. METHODS: By using Caco-2 (the human colonic adenocarcinoma cell lines) cell monolayers as an intestinal epithelial cell model, the permeability of PA was studied from apical side (AP side) to basolateral side (BL side) or from BL side to AP side. The PA was measured by reversed-phase high performance liquid chromatography coupled with UV detector at maximum absorption wavelength of 210 nm. Transport parameters and apparent permeability coefficients (Papp) were then calculated and compared with those of propranolol and atenolol, which were the transcellular transport markers for high and poor permeability respectively. RESULTS: The Papp values of PA were (9.50+/-2.20) 10(-7) cm/s from AP side to BL side, and (11.30+/-5.90) 10(-7) cm/s from BL side to AP side, respectively. Under the condition of this experiment, the Papp values were 1.45x10(-5) cm/s for propranolol and 4.22x10(-7)cm/s for atenolol. CONCLUSION: PA is transported through the Caco-2 cell monolayer in a concentration-dependent manner and the transport was linear with time. The absorption in apical to basolateral direction and secretion in basolateral to apical direction were poor and their Papp values were comparable to atenolol. Besides passive diffusion of PA, ATP is partially involved in its transport.

Chinese Journal of Minimally Invasive Surgery 2014;(10):903-905
Objective To analyze the clinical effects, as well as its advantages and disadvantages, of laparoscopic surgery for appendicitis in obese patients. Methods Clinical data of 80 obese patients receiving appendectomy, including 38 cases of open appendectomy and 42 cases of laparoscopic appendectomy, were analyzed retrospectively.The operative time, blood loss, analgesic and antibiotic use, postoperative fever, postoperative complications, length of hospital stay, and hospitalization cost were compared between the two operative methods. Results Conversions to open surgery were required in 2 patients in the laparoscopic group. There was no significant difference in operative time between the 2 groups (P >0.05).Compared with the open group, the laparoscopic group had less blood loss [(14.98 ±12.77) ml vs.(31.58 ±19.00) ml, t=-4.550, P=0.000], shorter time of postoperative antibiotic use [(2.7 ±1.0) d vs.(4.1 ±1.2) d, t=-5.470, P=0.000], less postoperative analgesics needed [5.0%(2/40) vs.26.3%(10/38),χ2 =6.802, P=0.009], less drainage [2.5% (1/40) vs.18.4% (7/38), χ2 =5.367, P=0.021], less postoperative fever [5.0%(2/40) vs.23.7%(9/38),χ2 =5.616, P=0.018], less postoperative wound healing [5.0%(2/40) vs.21.1%(8/38),χ2 =4.493, P=0.034], and shorter hospital stay [(5.9 ±3.2) d vs.(8.7 ±4.1) d, t=-3.345, P=0.001], but the higher cost of hospitalization [(7800 ±396) yuan vs.(4914 ±434) yuan, t=30.716, P=0.000]. Conclusion For obese patients with appendicitis, laparoscopic appendectomy has less surgical trauma, faster recovery, less postoperative pain, fewer complications,and shorter hospital stay, being a preferred method of treatment.
7.THE DISTRIBUTION OF LYSINE,METHIONINE,VALINE AND THREONINE IN WHOLE RICE GRAIN IN RELATION TO THE DEGREE OF MILLING IN MODERATION
Acta Nutrimenta Sinica 1956;0(01):-
Whole rice grain was dissected by hand into fractions of pericarp, ale-urone, scutellum, embryo and endosperm. For the convenience of having enough amount of samples for amino acids assay some of which were recom-bined and finally three parts, pericarp +aleurone layer, scutellum + embryo and endosperm, were obtained. Protein, lysine, methionine, threonine and valine contents were determined for each part. The data obtained indicated that although total weight of the first two parts accounted for only 7.27-8.43% of the whole grain, they contributed 14.5-15.8% protein, 29.0-30.5% lysine, 11.8% melhionine, 16.8% valine and 19.4% threonine, contained in the whole grain. During husking process it indicated that the lesser amounts of pericarp, aleurone, scutellum and embryo were retained and the larger percentage of protein and lysine was lost. This fact was identified either by a specially designed miller in the laboratory or a commonly used sand wheel miller in the factory. The suitable degree of milling for rice was discussed and it was proposed that 92% extration for rice rather rational.
8.LYSINE AND METHIONINE CONTENTS IN PROTEINS OF RICE VARIETIES GROWN IN DIFFERENT PROVINCES
Acta Nutrimenta Sinica 1956;0(02):-
Lysine and methionine contents were determined in proteins of 21 rice samples including 17 varieties grown in 11 provinces. Ranges of lysine and methionine contents on crude protein basis were 3.21-3.76% and 1.63-2.06% respectively. The lysine content was found to be negatively correlated with the protein content of rice, but no correlation was found in case of methionine when they were expressed on the basis of crude protein. The absolute amounts of lysine and methionine were positively correlated with protein contained in the samples. The importance of breeding rice variety with protein of high lysine content was discussed in relation to promoting the protein nutritive status in South China.

A convenient microbiological method with high accuracy for cystine assay was introduced. Common foods including cereals, beans, sweet potato, fishes and other aquatic products as well as meats were selected for cystine and methionine analysis. Based on the data obtained, a brief discussion was made on the way for resolution of sulfur amino acids problem inherently in our traditional soy-cereal based diet.
10.Activity and Localization of ?-GT, ANAE, AKP and G-6-P in the Epididymis of the Rat
Journal of Third Military Medical University 1984;0(02):-
Activity and localization of y-glutamyl transpeptidase (?-GT) , ?-Naph-thyl acetate esterase (ANAE) , alkaline phospbatase (AKP) and glucose-6-phosphatase (G-6-P) in the epididymis of the rat has been investigated histo-chemically by light microscopy.?-GT activity was mainly localized on the supranuclear region and the ste-reocilia of the epithelial cells. The intensity in the epithelium of the segment Ⅱ is the highest of the rat epididymis. There was a gradual decrease in the intensity of this enzyme from segment Ⅲ through Ⅳ and it was absent from the segment Ⅳ. Activity of ANAE in the segment Ⅳ, Ⅴ and Ⅵ was higher, but that in the segment Ⅰ,Ⅱ and Ⅳ was less. ANAE activity was localized throughout the cytoplasm of the epithelial cells in the segment Ⅰ,Ⅲ, Ⅴ and Ⅵ. Whereas the activity in the segment Ⅱ and Ⅳ was localized on the basal region of the epithelial cells. AKP activity was present in the basement membrane of the epididymal epithelium and the bloodvessel wall of subepithelial connective, tissue of the epididymal duct. G-6-P was distributed homogenously in the cytoplasm of the epithelial cells throughout the epididymal duct.The possible function of these enzymes in the rat epididymis are briefly discussed.
