OBJECTIVETo verify the clinical efficacy of acupuncture and moxibustion on depressive states of stroke patients' spouses.

METHODSForty-four subjects who were stroke patients' spouses and according with inclusive criteria with mild or moderate depressive states were randomly divided into an acupuncture-moxibustion group and a blank control group, 22 cases in each group. In the acupuncture-moxibustion group, acupuncture was applied at Baihui (GV 20), Shenting (GV 24), Sishencong (EX-HN 1), Hegu (LI 4), Zusanli (ST 36) and Taichong (LR 3), and suspended moxibustion was used at Shenque (CV 8), Guanyuan (CV 4) and Zhongwan (CV 12). The treatment was given twice a week for continuous 8 weeks. In the blank control group, neither acupuncture nor moxibustion treatment was given, and the patients were only treated with health and psychological guidance. Before treatment and after 8-week treatment, scores of self-rating depression scale (SDS) and numbers of insomnia severity grade were observed.

RESULTSIn the two groups, the scores of SDS were both reduced than those before treatment (both P<0.05), and the decrease in the acupuncture-moxibustion group was more obvious (P<0.05). After treatment, the number of insomnia severity grade in the acupuncture-moxibustion group was improved than that before treatment (P<0.001), and the improvement was evidently superior to that in the blank control group (P<0.05). The numbers of insomnia severity grade of the blank control group before and after treatment had no statistic significance (P>0.05).

CONCLUSIONThe acupuncture and moxibustion intervention plan has clinical treatment significance on the improvement of mild and moderate depressive states for the stroke patients' primary caregivers who are the patients' spouses.

Postoperative gastrointestinal dysfunction (PGD) is one of the most common complications following major surgeries under general anesthesia (GA). Despite ongoing research and new drug treatments, abdominal distension within 24 h postoperatively occurs in 8%-28% of all surgeries. We aim to analyze the effectiveness of preventing PGD by preoperatively stimulating Neiguan (PC6), Zusanli (ST36) and Shangjuxu (ST37) bilaterally twice a day compared with sham-acupuncture treatment and standard treatment.

Purpose To evaluate the feasibility of using dual-energy CT scanner to differentiate two contrast media bismuth and gadolinium. Materials and Methods Two phantoms containing contrast media of different ratio were scanned on dual-energy CT. Group 1 was mixture of iodine and gadolinium solution with volume ratio of 0∶1, 1∶6, 1∶1, 6∶1 and 1∶0. Group 2 was mixture of iodine and bismuth solution with mass ratio of 0∶1, 1∶6, 1∶1, 6∶1, 1∶0. Monoenergetic image reconstruction was performed at 80 keV. Liver VNC software was used for virtual scanning and iodine concentration analysis. Results Under 80 keV reconstruction, the measured CT attenuation of Group 1 was 379-383 HU, and 170-173 HU in group 2. The iodine concentration of two groups was not signiifcantly different between the calculated and actual iodine concentration (P>0.05). The dual-energy CT can distinguish two contrast media. Iodine and gadolinium contrast media were not statistically different, while iodine and bismuth contrast media agent could be easily differentiated. Conclusion Dual-energy CT can distinguish two contrast media with different attenuation.

OBJECTIVETo observe the efficacy of preventing constipation by electroacupuncture intervention in ischemic stroke patients at acute stage.

METHODSThree hundred and forty ischemic stroke patients who matched the inclusive criteria were randomly divided into an electroacupuncture (EA) group and a routine treatment group, 170 cases in each one. In the EA group, based on routine western treatment, rehabilitation training and common acupuncture, Tianshu (ST 25) and Zusanli (ST 36) were selected and connected to SDZ-V Hwato brand electric acupuncture apparatus respectively, given stimulation of dense-disperse wave (10 Hz/50 Hz) with electric current of 0.1 to 1.0 mA, once every day and 5 times a week in the first 2 weeks, 2 times a week in the latter 2 weeks. In the routine treatment group, only basic treatment was applied. In the two groups, the course of treatment was 4 weeks and 8 weeks' follow-up was required after treatment. The actual numbers who independently defecated less than 3 times a week after 1 to 4 weeks' treatment and in the 4th and the 8th weeks' follow-up and condition taking laxative medicines during the 12 weeks in the two groups were observed and compared.

RESULTSCompared on the numbers of constipation cases after 1 to 4 weeks' treatment, those in the EA group were all less than those in the routine treatment group [24.7% (42/170) vs. 36.5%(62/170), 18.8% (32/170) vs. 30.6% (52/170), 10.5% (17/162) vs. 27.5% (44/160), 9.3% (15/162) vs. 19.4% (31/160),P<0.05, P<0.001]. In the 4th and the 8th weeks' follow-up, numbers in the EA group were still less than those in the routine treatment group [9.0% (14/156) vs. 18.1% (28/155), 7.7% (12/155) vs. 16.9 (26/154) both P<0.05)]. During the 12 weeks, the number of cases who took laxative medicines in the EA group was less than that in the routine treatment group [21.2% (36/170) vs. 34.7% (59/170), P<0.05].

CONCLUSIONThere is clinical significance to electroacupuncture at Tian-shui (ST 25) and Zusanli (ST 36) coibined with basic comprehensive treatment for preventing and treating constipation symptom in ischemic stroke acute stage.

Aim To investigate the effect of p38 MAPK AS-ODNs on the expression of GLT-1 during the induction of brain ischemic tolerance induced by cerebral ischemic preconditioning (CIP).Methods Eighty healthy male Wistar rats with permanent occlusion of the bilateral vertebral arteries were randomly divided into 6 groups: ①Sham group (n=10);②CIP group (n=10);③ischemic insult (Ⅱ) group (n=10);④CIP+Ⅱ group (n=10);⑤p38 MAPK AS-ODNs+CIP+Ⅱ group (n=30);⑥p38 MAPK S-ODNs+CIP+Ⅱ group (n=10).Group ⑤ was divided into 5 nmol, 10 nmol and 15 nmol subgroups according to the dose of p38 MAPK AS-ODNs (n=10).The dose of p38 MAPK S-ODNs was 15 nmol.All the rats were sacrificed 6 h and 2 d after the sham operation or the last time of global brain ischemia reperfusion.Western blot and immunohistochemistry analysis were used for detecting the expression of p-p38 MAPK and GLT-1 protein.Results CIP moderately up-regulated the expression of p-p38 MAPK and significantly up-regulated the expression of GLT-1 protein, inhibited the excessively up-regulation of p-p38 MAPK and the down-regulation of GLT-1 induced by ischemic insult.p38 MAPK AS-ODNs significantly inhibited the up-regulation of p-p38 MAPK and GLT-1 protein in a dose-dependent manner during the induction of brain ischemic tolerance by CIP.Conclusion p38 MAPK AS-ODNs inhibit the up-regulation of GLT-1 during the induction of brain ischemic tolerance induced by CIP.

OBJECTIVETo compare the clinical effective differences between acupuncture-moxibustion and Chinese herbs for functional dyspepsia with emotional disorder.

METHODSEighty patients were randomly divided into an observation group and a control group, 40 cases in each one. In the observation group, based on the basic treatment Zusanli (ST 36), Yinlingquan (SP 9), Zhongwan (CV 12), Danzhong (CV 17), Neiguan (PC 6), Taichong (LR 3), Ganshu (BL 18), Geshu (BL 17) and Danshu (BL 19) were selected once every day or every other day. The treatment was given 14 times. In the control group, based on the basic treatment individual therapy of Chinese herbs according to syndrome differentiation was applied,one dose a day. Patients were treated for 4 weeks in the two groups. The scores of self-rating depression scale (SDS), the main symptoms and satisfied degree by self-rating for treatment were observed before and after 4-week treatment in the two groups. Also, the rate and the average time of return visit were compared in 6 months after treatment. Results After treatment, the SDS scores and the main symptoms scores were all improved compared with those before treatment in the two groups (all P< 0. 05). After 4-week treatment, the improvement of the SDS score in the observation group was better than that in the control group (48. 9±8. 5 vs 53. 1±8. 0, P<0. 05). After 1-week treatment and 4-week treatment, the improvements of the main symptoms in the observation group were superior to those in the control group (2. 7 ± 1. 0 vs 3. 3±0. 9, 1. 5±0. 9 vs 2. 3±1. 1, both P<0. 05), and the satisfied degree scores by self-rating were better than those in the control group (3. 0±1. 1 vs 3. 8±1. 3, 2. 0±1. 4 vs 2. 9±1. 5, both P<0. 05). In 6 months after treatment,the return visit rate in the observation group was 42. 5% (17/40), and it was lower than 70. 0% (28/40) in the control group (P<0. 05). The average time of return visit in the observation group was less than that in the control group (1. 0±0.8 vs 1. 9±0. 7, P<0. 05).

CONCLUSIONThe effect of acupuncture-moxibustion or functional dyspepsia with emotional disorder is better than that of Chinese medicine.

Objective To investigate the effect of low oxygen tension (7.5% O2) on human embryo development in vitro and outcome of women undergoing IVF-ET. Methods The data of 280 routine IVF cycles with fresh embryo transfer on day3 conducted in the 2nd People's Hospital of Yunnan Province from February 2012 to August 2013 were retrospectively analyzed. Two groups, 7.5%O2 low oxygen tension (n=120) and 20%O2 high oxygen tension (n=160),were setup for early embryo (D1-D3) development in vitro. Results Good quality embryo on day 3 in low oxygen tension group showed morphologically appearance of blastomere mutually clinging to each other,a characteristic of slight compaction. Higher rate of good quality embryo (66.22%V. 47.54%) and of clinical pregnancy (53.33%v. 39.22%) were found in the low oxygen tension group. There were no significantly differences in rates of fertilization,cleavage and embryo utilization respectively between the two groups ( all>0. 05) . Conclusion High quality early stage human embryos can be developed in vitro in low oxygen tension, and may improve clinic outcome of IVF.

PurposeTo evaluate the effect of tube current on the pseudo-enhancement of renal cyst by simulating the phantom model of simple renal cyst.Materials and Methods 10% glucose and iodine solution with a certain concentration was used to simulate the renal parenchymal background concentration in plain scan, moderate enhancement and maximum enhancement respectively. The diameters of the cysts were 6 mm, 10 mm and 15 mm, respectively, and the cysts were divided into three groups according to different tube current: 119 mAs (group A), 178 mAs (group B) and 297 mAs (group C) while the tube voltage were all 120 kV. Whether pseudo-enhancement exists in cyst under different conditions was determined using an increase of CT value of 10 HU as the critical value. Results In group A, there was pseudo enhancement at the 240 HU background, and it was most significant with the diameter of 6 mm, which was 21 HU. In group B, pseudo-enhancement occurred in cysts with diameter of both 10 mm and 6 mm under the background of 180 HU and 240 HU, moreover, the biggest difference was 20.4 HU and it occurred in cyst with diameter of 6 mm under the background of 240 HU. In group C, pseudo-enhancement only occurred in cyst with diameter of 6 mm under the condition of 125 HU and 240 HU background concentration. Background concentration (F=17.587, P<0.01) and cyst diameter (F=4.214,P<0.05) had greater impact on cyst pseudo-enhancement, the higher the background concentration and smaller the diameter, more significantly the pseudo-enhancement would occur. With the increase of the tube current, the CT volume dose index increased, and the pseudo enhancement value was smaller, but there was no obvious regularity of pseudo-enhancement occurrence rate in cysts with different background concentration and diameter in each group.Conclusion The increase of tube current cannot completely eliminate cyst pseudo-enhancement. High background concentration and small diameter cyst are important factors in pseudo-enhancement. However, increasing the tube current can reduce the probability of occurrence of pseudo-enhancement to some extent. For those with heavier body weight, it might be necessary to increase the tube current to improve image quality and reduce the occurrence of renal cyst pseudo-enhancement.
