Role of intracellular Ca2+ in regulating NHE3 expression in Caco-2 cells during rotavirus infection / 中华微生物学和免疫学杂志

Objective To investigate the effects of rotavirus ( RV) on the expression and bioactiv-ity of Na+-H+ exchanger 3 ( NHE3 ) in Caco-2 cells and the possible regulatory mechanism. Methods Caco-2 cells expressing NHE3 were constructed and divided into four groups as follows: control ( CTL ) group, RV group, BAPTA-AM ( a Ca2+ chelator) group and BAPTA-AM+RV group. Na+-H+ exchanger ac-tivity and NHE3 expression on cell surface were determined using BCECF-AM and biotinylation assay, re-spectively. Expression of Cdc42 at protein level was measured by Western blot. Results Compared with the control group, RV infection significantly decreased the activity of NHE3 and its expression on cell surface. BATPA-AM antagonized the inhibitory effects on NHE3. Moreover, the expression of Cdc42 at protein level was increased following RV infection, which was also antagonized by BATPA-AM. Conclusions Intracellu-lar Ca2+-mediated Cdc42-dependent endocytosis pathway might be involved in regulating the expression and bioactivity of NHE3 during RV infection.

Subacute insomnia treated with 's three-promotion needling method: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the differences in the sleep quality and the effects on insomnia severity between 's three-promotion needling method and the oral administration of estazolam.@*METHODS@#A total of 70 patients of subacute insomnia were randomized into a three-promotion needling group and a medication group, 35 cases in each one. In the three-promotion needling group, the mild promotion technique with the filiform needle, the warm promotion technique with the fire needle and the strong promotion technique with the three-edged needle were adopted in combination. The acupuncture with the filiform needle was used at Baihui (GV 20), Sishencong (EX-HN1), Shenting (GV 24), Shenmen (HT 7), etc, The treatment was given 3 times a week, once every 2 days. The pricking technique with fire needle was applied to Ganshu (BL 18), Xinshu (BL 15), Feishu (BL 13), Pishu (BL 20), Shenshu (BL 23) and Geshu (BL 17), once every 3 days, twice a week. The bleeding technique with the three-edged needle was used at the ear apex, once every 2 days, 3 times a week. In the medication group, the estazolam tablets were taken orally before sleep, 1mg once every 2 days. The treatment was given consecutively for 4 weeks in the two groups. Separately, before treatment, in 2-week treatment and in 4-week treatment as well as in 1-month follow-up after treatment, the Pittsburgh sleep quality index (PSQI) and the insomnia severity index (ISI) scores were recorded in the patients of the two groups. The clinical effects were evaluated in the two groups.@*RESULTS@#In 2 weeks and 4 weeks of treatment, as well as in the follow-up, PSQI scores and ISI scores were all reduced obviously as compared with those before treatment in the two groups (all <0.05). In the three-promotion needling group, the PSQI score at each time point was reduced much more obviously as compared with the medication group (all <0.05). In the follow-up, the ISI score in the three-promotion needling group was lower than the medication group (<0.05). The total effective rates were 97.2% (34/35) and 91.4% (32/35) at the end of treatment and in the follow-up respectively in the three-promotion needling group, higher than 85.7% (30/35) and 71.4% (25/35) in the medication group (both <0.05).@*CONCLUSION@#'s three-promotion needling method much more effectively improves the sleep quality and reduces insomnia severity in the patients of subacute insomnia. This therapy presents the satisfactory short-term and long-term effects.

Effect of rotavirus infection on regulating the expression of Na+-H+ exchanger 3 in Caco-2 cells via clathrin dependent endocytosis pathway / 中国感染与化疗杂志

Objective To observe the effect of rotavirus (RV) infection on expression level and bioactivity of Na+-H+ exchanger 3 (NHE3) in Caco-2 cells. Methods Model of NHE3-expressing Caco-2 cells was constructed and studied in terms of intervention: control, RV, clathrin antagonist chlorpromazine (CPZ), and CPZ + RV. NHE3 activity and NHE3 protein amount on cell surface were determined by BCECF-AM and biotinylation, respectively. Expression level of clathrin was assayed by Western blot. Results Compared with control group, NHE3 activity and NHE3 surface protein level significantly decreased when the cells were treated with RV. These effects could not be completely cancelled by clathrin antagonist CPZ. Moreover, RV treatment could increase cellular protein level of clathrin, which was cancelled by CPZ. Conclusions The effect of RV infection on NHE3 expression level and biological activity may be related to clathrin-dependent endocytosis pathway, and may be also affected by other endocytosis pathways.

Quantification and construction of the effective point calculation model of ionization chamber in Monacao treatment planning system / 中华放射肿瘤学杂志

Objective Because of statistical noise in Monte Carlo dose calculations,the effective point doses may not be accurately calculated.A user-defined sphere volume was adopted to substitute the effective point to take sphere sampling around the effective point,which minimize the random errors and improve the accuracy of statistical dose.Methods Direct dose measurements were performed at 0°and 90° using a 0.125 cm3 Semiflex ionization chamber (IC) 31010 isocentrically placed in the center of a homogeneous Cylindric sliced RW3 phantom (PTW,Germany).In the scanned CT phantom series,the sensitive volume length of the IC (6.5 mm) was delineated and the isocenter was defined as the simulated effective point.All beams were simulated in the treatment planning system (TPS) in accordance to the measured model.The grid spacing was calculated by 2 mm voxels and the relative standard deviation should be ≤ 0.5％.The statistical and measured doses were statistically compared among three IC models with different electron densities (ED;esophageal lumen ED =0.210 g/cm3 for model A,air ED =0.001 g/cm3 for model B and the default CT scanned ED for model C) at different sampling sphere radius (2.5,2.0,1.5 and 1.0 mm) to evaluate the effect of Monte Carlo.calculation uncertainty upon the dose accuracy.Results In the Monaco TPS,the statistical value was in the highest accordance with the measured value with an absolute average deviation of 0.49％ when the IC was set as esophageal lumen ED =0.210 g/cm3 and the sampling sphere radius was 1.5 mm.When the IC was set as air ED=0.001 g/cm3 and default CT scanned ED,and,the recommended statistical sampling sphere radius was 2.5 mm,the absolute average deviations were 0.61％ and 0.70％.Conclusion In the Monaco TPS,the calculation model with an ED of 0.210 g/cm3 and a sampling radius of 1.5 mm is recommended for the ionization chamber 31010 to substitute the effective point dose measurement to decrease the random stochastic errors of Monte Carlo.

Influence on the prognosis of patients with lymph node micrometastasis of gastric cancer detected by carcinoembryonic antigen detection / 中国医师进修杂志

Objective To investigate the influence of the lymph node micrometastasis and its clinicopathological features on postoperative disease-free survival rate for patients with gastric cancer.Methods The study included 120 patients with pT1-3NoMo gastric cancer. The relationships between clinicopathological features or carcinoembryonic antigen (CEA) positive expression and postoperative disease-free survival rate were analyzed. Results In clinicopathological factors, multivariate analysis identified CEA positive expression was significantly correlated with tumor diameter (P = 0.011 ),depth of tumor invasion (P= 0.027) and lymphatic vessel invasion (P= 0.001 ) in lymph node positively. The average postoperative follow-up was (53.14 ± 16.75) months. There was statistical correlation between the tumor diameter( P = 0.018 ) or depth of tumor invasion ( P = 0.015 ) and postoperative disease-free survival rate. The disease-free survival rate was 90.91% ( 80/88 ), 86.36% ( 19/22 )and 40.00% (4/10) for the lymph node CEA negative,isolated tumor cells (IT Cs) and micrometastasis,respectively. There was significant difference between micrometastasis and the lymph node CEA negative (P= 0.000) or ITCs (P = 0.009), however, the lymph node CEA negative and ITCs was no significant difference (P = 0.438 ). Lymph node micrometastssis of gastric cancer was detected in 10 patients who should belong to stage pN1,the restage rate was 8.33%(10/120). Conclusions If the patients were found micrometastasis in lymph node with high-risk stage pT1-3NoMo gastric cancer for whom chemotherapy may be recommended,because of its high recurrence and poor prognosis.
