Objective To explore the effect of body mass and body mass index (BMI) on proton hepatic MRS water suppression at 3.0T. Methods The prospective study of hepatic proton MRS was performed with GE Signa Excite HD 3.0T system and eight-channel torso phased-array coils using PRESS sequence in 44 healthy subjects. Liver spectra were collected with TR of 1500 ms, TE of 30 ms, VOI of 2 cm×2 cm×2 cm and NSA of 64 times. Areas and heights for metabolites resonances were caulculated. Results Group with small mass has lower height ([161.2±8.5] cm vs [167.7±6.2])cm, lower BMI ([20.8±2.3] kg/m~2 vs [25.6±2.6]kg/m~2), better water suppression effect (min-max: 90-96 vs 65-94;median: 94 vs 93), smaller height (min-max: 1.41×10~4-5.76 ×10~5 vs 3.45×10~4-1.75×10~6;median: 9.00×10~4 vs 2.58×10~5) and integrated area (min-max: 4.27×10~4-2.00×10~7 vs 1.24×10~5-5.00×10~7;median: 2.64×10~5 vs 1.19×10~6)of Lip2 than larger weight group. Standardized lipid content (min-max: 0-0.11 vs 0-0.96;median: 0.01 vs 0.04) was less. Group with lower BMI had lower weight ([55.2±8.2]kg vs [71.2±7.8]kg), smaller age ([33.2±11.9]years vs [45.6±9.4]years), better water suppression effect(min-max: 90-96 vs 65-95;median: 94 vs 93) smaller of height (min-max: 1.41×10~4-5.76×10~5 vs 3.45×10~4-1.75×10~6;median: 7.37×10~4 vs 2.11×10~5) and integrated area (min-max: [4.27×10~4-2.00×10~7] vs [1.24×10~5 -5.00×10~7];median: 2.64×10~5 vs 1.19×10~6) of Lip2 than larger weight group. Standardized lipid content (min-max: 0-0.08 vs 0.01-0.96;median: 0.01 vs 0.04) was less. There was significant correlation among water suppression, weight (r=-0.478, P=0.001) and BMI (r=-0.494, P=0.001). Conclusion Lipid accumulation in the liver may be the result of increased fat portion of the body depending on mass and BMI, and hinder to achieve effective water suppression.

Objective To evaluate the effect of intravenous Gd-DTPA on 3.0T proton MR spectroscopy (MRS) water suppression and shimming. Methods Prospective study of proton MRS was performed with GE Signa Excite HD 3.0T system and eight-channel phased-array coils with PRESS sequence (head, liver and kidney, respectively). Routine auto prescan program was operated to record full width half maximum (FWHM) and water suppression (WS%). Routine scan was performed after injection of Gd-DTPA, then prescan program was reoperated to record FWHM and WS%. The data of FWHM and WS% in head, liver and kidney were compared between before and after injection of Gd-DTPA with the Wilcoxon matched pairs signed test. Results WS% of spectroscopy of head and liver after administration of Gd-DTPA decreased significantly (T_+=12, T_-=66, P=0.02; T_+=0, T_-=45, P=0.007). The effect of shimming of kidney after administration of Gd-DTPA was poor (T_+=0, T_-=435, P<0.001) and WS% of spectroscopy of kidney after administration of Gd-DTPA decreased significantly (T_+=0, T_-=435, P<0.001). Conclusion WS% of spectroscopy in head, liver and kidney can be impacted negatively by Gd-DTPA. Gd-DTPA has great influence on shimming of spectroscopy of kidney, but has little influence on shimming of spectroscopy of head and liver. It is better to acquire MRS data before administration of contrast medium in kidney.

Objective To analyze the correlations between liver lipid level determined by liver 3.0 T 1H-MRS in vivo and influencing factors using multiple linear stepwise regression. Methods The prospective study of liver 1H-MRS was performed with 3.0 T system and eight-channel torso phased-array coils using PRESS sequence. Forty-four volunteers were enrolled in this study. Liver spectra were collected with a TR of 1500 ms ,TE of 30 ms, volume of interest of 2 cm ×2 cm ×2 cm, NSA of 64 times. The acquired raw proton MRS data were processed by using a software program SAGE. For each MRS measurement, using water as the internal reference, the amplitude of the lipid signal was normalized to the sum of the signal from lipid and water to obtain percentage lipid within the liver. The statistical description of height, weight, age and BMI, Line width and water suppression were recorded, and Pearson analysis was applied to test their relationships. Multiple linear stepwise regression was used to set the statistical model for the prediction of Liver lipid content. Results Age (39.1 ± 12. 6) years, body weight (64.4 ± 10. 4) kg,BMI (23.3 ±3.1) kg/m2, linewidth (18.9 ±4.4) and the water suppression (90.7 ±6.5)% had significant correlation with liver lipid content (0.00 to 0.96%, median 0. 02% ), r were 0.11,0. 44,0. 40,0. 52, - 0. 73 respectively(P < 0. 05 ). But only age, BMI, line width, and the water suppression entered into the multiple linear regression equation. Liver lipid content prediction equation was as follows: Y =1.395-(0.021 × water suppression) + (0.022 × BMI) + (0.014 × line width) - ( 0. 064 × age),and the coefficient of determination was 0.613, corrected coefficient of determination was 0.59. Conclusion The regression model fitted well, since the variables of age, BMI, width, and water suppression can explain about 60% of liver lipid content changes.

Objective To explore the short-term influences of conventional internal medical treatment combined with escitalopram on cognitive function and cardiac function in elderly patients with chronic heart failure (CHF) complicated with depression disorder.Methods A total of 97 patients with CHF complicated with depression disorder in Chongqing Ninth People's Hospital,from October 2014 to October 2015,were selected and randomly divided into the antidepressant group and control group.Both groups were undergoing conventional internal medical treatment.Additionally,patients in the antidepressant group were administrated with escitalopram,while patients in the control group were treated with placebo.The degree of depression and anxiety and cognitive function were assessed by using 24-item Hamilton depression scale (HAMD-24),14-item Hamilton anxiety scale (HAMA-14) and Montreal cognitive assessment(MoCA) scale,and the plasma level of NT-proBNP,left ventricular end-diastolic dimension (LVEDD) and left ventricular ejection fraction (LVEF) were measured before and after 6-week treatment.Results After 6-week treatment,the HAMD-24 and HAMA-14 scores and plasma level of NT-proBNP in antidepressant group were lower than those in the control group,while the attention score and LVEF were greater than those in the control group,there were statistically significant differences(P＜0.05).After 6-week treatment,no statistically significant difference was found in other observed indicators between the two groups(P＞0.05).Conclnsion For elderly patients with chronic heart failure complicated with depression disorder,it is indicated that escitalopram could not only relieve their anxiety and depression,but also improve their cardiac function and attention.

Objective: To examine the impact of laser-assisted hatching (LAH) technique on perinatal outcomes in blastocyst culture of low-grade cleavage embryos, so as to provide insights into improving the utilization of low-grade cleavage embryos and embryo quality. Methods: A total of 369 single live births after transfer of thawed blastocysts following in vitro fertilization or intracytoplasmic sperm injection at Zhejiang Provincial People's Hospital were selected as subjects, and they were divided into 51 conventional culture blastocysts and 318 LAH blastocysts based on whether LAH was performed on day 4 of blastocyst culture. Gestational age, birth weight, birth defects and maternal perinatal information were collected, and the prevalence of premature birth, birth weight and birth defects were analyzed after propensity score matching (PSM). Results: After PSM, 98 matched cases were included in the study. There were no statistically significant differences in maternal age, body mass index, type of infertility and blastocyst age (P>0.05), indicating effective matching. The birth weight of offspring in the LAH group was lower than that in the conventional culture group [(3 261.08±432.24) g vs. (3 464.18±444.46) g; P<0.05]. Conclusion The birth weight of offspring can be reduced by using LAH during blastocyst culture of low-grade cleavage embryos.

Objective:To investigate the safety and effect of complete mesocolie excision (CME) combined with arterial infusion chemotherapy (AIC) and intra-peritoneal interstitial sustained-release chemotherapy (IPISRC). Methods:A total of 104 patients were classified under the experimental group and underwent CME combined with AIC and IPISRC. The other 98 patients were classified un-der the control group and only received radical surgery. Pre-and post-operative blood routine examinations, as well as liver and kidney function tests, were conducted for both groups. Post-operative adverse reactions and incidence of complications were recorded. Cancer and para-neoplastic tissues were sampled in experimental group. The post-surgery 5-fluorouracil (5-FU) concentration in the drainage fluid as well as those in the peripheral blood , were determined. Three-year follow-ups were conducted, during which the local recur-rence rate, liver metastasis, progression-free survival rate, and total survival rate were recorded. Results: No significant differences were found in the white blood cell count, hemoglobin count, liver and renal functions of the patients before and after the surgery, and rate of adverse reaction and complications between the two groups after surgery (P>0.05). In experimental group , the 5-FU concentra-tion was significantly higher in the cancer tissues than in the para-neoplastic tissues . The 5-FU concentration in experimental group was also significantly higher in the intra-peritoneal drainage liquid and reached its peak in the peripheral blood on day 3 post-surgery . Local recurrence and liver metastasis rates were significantly lower in experimental group than those in control group, whereas the pro-gression-free and three-year overall survival rates were significantly higher in experimental group than in control group (P<0.05). Con-clusion:The tharepy of pations of experimental goup is safe and effective. This method significantly improves the progression-free and three-year survival rates of the patients as well as significantly reduces the local recurrence and liver metastasis rates of colon cancer.
