Objective To explore the clinical effect of Chinese medicine enema combined with massage of Hui medicine for treatment of patients with ulcerative colitis (UC).Methods A prospective randomized controlled trial (RCT) was conducted, 390 patients with UC admitted to Department of Traditional Chinese Medicine (TCM) of Ningxia Hui Autonomous Region People's Hospital from January 2013 to December 2014 were enrolled, and they were divided by using random envelope method into the western medicine control group (88 cases), simple TCM enema group (102 cases), simple massage of Hui medicine group (94 cases) and enema combined with massage group (106 cases). The patients in western medicine control group took sulfasalazine orally, once 0.75 g, thrice a day. The simple TCM enema group adopted the self prepared Shexue Fuyang decoction (ingredients: carbonized sanguisorba root 15-20 g, bletilla striata 15 g, patrinia 15-30 g, sculellaria barbata 15-30 g, Chinese goldthread 15 g, radix glycyrrhizae preparata 15 g, Fry terminaliachebuia 10 g, yam 15-30 g, india madder root 15 g) retention enema once a day. The following principles should be followed: firstly, the dose of drug should be large enough (250 mL), secondly the speed of enema should be relatively slow and it finished in 15-20 minutes, thirdly the temperature of decoction should be kept at moderate degree about 39-41 ℃ (a warm bag being around the enema tube), and lastly, the patient's posture should be changed (lying left-side for 20 minutes, lying at chest-abdomen position for 20 minutes, lying right-side for 20 minutes). In massage of Hui medicine group, based on the location and size, depth and seriousness of the lesion, the doctor would selectively use palm or index finger to carry out massage manipulations of pressing, fractioning, rubbing or grasping for different disease situations of patients, once 30 minutes pre day. The patients in enema combined massage group were treated with the same methods as above, and the therapeutic course of the four groups was 15 days; at the end of experiment,the therapeutic effects and the improvement of main symptoms in four groups were observed.Results The clinical total effective rates of Chinese medicine enema group, massage of Hui medicine group, enema combined massage group were obviously higher than the rate of western medicine control group [78.4% (80/102), 85.1% (80/94), 93.4% (99/106) vs. 62.5% (55/88), allP < 0.05]; the symptom integrals, such as abdominal pain, diarrhea, tenesmus, purulent blood stool, fever, etc. were significantly decreased after treatment in the TCM enema, massage and combined treatment groups, and the integrals of the three treatment groups were obviously lower than those in the western medicine control group (abdominal pain: 0.45±0.75, 0.56±0.57, 0.35±0.96 vs. 1.13±0.86, diarrhea: 0.76±0.91, 0.78±0.69, 0.55±0.81 vs. 1.43±0.34, tenesmus: 0.52±0.37, 0.44±0.23, 0.21±0.13 vs. 0.72±0.98, purulent blood stool: 0.43±0.34, 0.50±0.24, 0.52±0.76 vs. 0.68±0.44, fever: 0.32±0.56, 0.35±0.65, 0.26±0.45 vs. 0.49±0.77, allP < 0.05).Conclusion The therapeutic effects of Shexue Fuyang decoction enema combined with massage of Hui medicine for treatment of patients with UC are better than those of each of the following treatment alone: western medicine, Chinese medicine enema or medical massage treatment.

Objective To understand the cause of chest pain (precordium indisposition) in children and explore the thread of thought in its analysis.Methods Clinical data of 314 children with chest pain who visited the cardiovascular department for children of our hospital were collected and analyzed to study its causes.Results The cause could be attributed to organic cardiac diseases in 43 of 314 children (13.7%) with chest pain,to non-organic cardiac diseases in 108 (34.4%),to psychiatric-psychological factors in 60 (19.1%) and to unknown cause in 41 (13.1%).Average age of children with organic cardiac diseases was younger than that of children with other causes (P<0.05).Symptoms accompanied simultaneously in children with organic cardiac diseases were much more frequent significantly than those in them with non-organic cardiac chest pain and unknown causes (P<0.05).Conclusions Chest pain in children could be caused by a few causes,which was non-specific symptom for organic cardiac diseases,so, more should be taken into account in analyzing the cause of chest pain in children.

Objective To study the value of the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in gene diagnosis on spinal muscular atrophy (SMA).Methods PCR-RFLP method was used to detect the homozygous deletion of the exon 7 or exon 8 of SMN gene in 20 SMA patients of Type Ⅰ,Ⅱ,Ⅲ and 15 normal individuals.Results Homozygous deletion of exon 7 and exon 8 of the SMN gene were all identified 7/7 in SMA TypeⅠpatients, and 5/5 and 4/5 respectively in SMA Type Ⅱ patients, but only 1/8 of SMA Type Ⅲ patients, and no homozygous deletion was found in the normal controls.Conclusions PCR-RFLP might be recommended as an effective diagnosis for spinal muscular atrophy Type Ⅰand Ⅱ patients, whereas the method might not be as useful in Type Ⅲ as in Type Ⅰand Ⅱ for the gene diagnosis.

Objective To investigate the effects of Lokomat robotic-assisted gait training combined with drop foot stimulator on gait function in patients with stroke. Methods Thirty-six stroke patients were randomly divided into control group (n=18) and observation group (n=18). Both groups received routine rehabilitation training. The control group accepted Lokomat robotic-assisted gait training, while the ob-servation group worn drop foot stimulator in addition. The training intensity was 30 minutes every day, five days per week for 6 weeks. Fugl-Meyer Assessment-Lower Limb (FMA-LL), Functional Ambulation Category (FAC) and footprint analysis were used to evaluate the motor ability of lower limbs, walking ability and gait before and after training. Results There was no significant difference in the scores of FMA-LL, FAC and gait parameters (walking speed, stride width, stride length difference) before training (t<0.765, Z=0, P>0.05). The scores of FMA-LL, FAC and walking speed improved, and the stride width and stride length difference decreased after training (t>2.190, Z>3.630, P<0.05). After training, the scores of FMA-LL, FAC, walking speed and stride length difference were better in the observation group than in the control group (t>2.030, Z=-2.560, P<0.05), however, there was no significant difference in stride width between two groups (t=0.570, P>0.05). Conclusion Lokomat robotic-assisted gait training combined with foot drop stimulator could improve the lower limb motor func-tion and gait ability in patients with stroke, and the effect might be better than using Lokomat robotic-assisted gait training only.

AIM: To observe the effect of hydrogen sulfide (H_2S) on the rat cardiac function in vitro, to explorer the physiological regulation of endogenous H_2S on myocardial action. METHODS: H_2S concentration and production in the rat myocardial tissues were detected. The expression of CSE (a kind of key enzyme of endogenous H_2S production) mRNA in myocardial tissues was screened by RT-PCR. Langendorff apparatus was used to perfuse the rat heart in vitro. After 20 minutes of stabilization, NaHS (10~-6 -10~-3 mol/L) were added cumulatively in order to the perfusive fluid, and another group applied physiological concentration NaHS (4?10~-4 mol/L), continuously perfusion for 20 min, heart rate (HR), difference of left ventricular pressure (△LVP), left ventricular peak rate of contraction (+LV dp/dt_~max ), peak rate of relaxation (-LV dp/dt_~max ) and coronary perfusive flow (CPF) were measured at the times. Finally, glibenclamide was applied to block the K_~ATP channel of heart, to observe the effect of NaHS at physiological concentration on cardiac function. RESULTS: NaHS concentration-dependently inhibited left ventricular ?dp/dt_~max and △LVP (P

In this study, we aimed to investigate the influences of conditioned medium from human umbilical vein endothelial cells (HUVEC) on cancer stem cell phenotype of human hepatoma cells. HUVEC and human hepatoma cells (MHCC97H) were cultured, respectively, and then the MHCC97H cells were co-cultured with conditioned medium from HUVEC (EC-CM) with Transwell system. Anti-cancer drug sensitivity, colony-formation, migration/invasion ability, expression of cancer stem cell marker and sphere formation were performed to determine the cancer stem cell phenotype in MHCC97H cells. We found that MHCC97H cells co-cultured with EC-CM exhibited significantly higher colony-formation ability and lower sensitivity of anti-cancer drugs 5-FU and Cis. Transwell assay showed that treatment with EC-CM obviously increased migration and invasion of MHCC97H cells. Moreover, increased sphere forming capability and expression of CD133 in MHCC97H cells were observed after co-cultured with EC-CM. These results suggested that EC-CM could promote cancer stem cell phenotype of hepatoma cells.
