ObjectiveTo explore effects of food viscosity and sex on hyoid motion during swallowing in normal elder.MethodsVideofluoroscopic studies were done in 60 healthy elder. Hyoid motion during swallowing food with different viscosity was measured.ResultsOlder male had longer movement duration, greater amplitudes of upward and forward movement than older female (P<0.05). Amplitudes of upward movement in jam thick swallow and bread thick swallow were greater than that in liquid swallow (P<0.01). Bread thick swallow had the longest movement duration; liquid swallow had shortest movement duration.ConclusionThe hyoid bone moves both upward and forward during swallowing, the amplitude of upward displacement is highly variable and influenced by food viscosity. The duration and amplitude of hyoid motion in male or female are different.

OBJECTIVETo observe the effect of long-term application of Shengmai Capsule (SMC) on recovery of patients after myocardial infarction.
METHODSA total of 120 myocardial infarction patients were: assigned into two groups. Changes of angina pectoris, electrocardiogram (ECG), living capacity and heart function in patients were observed after 6-month treatment.
RESULTSThe total effective rate in alleviating angina: pectoris was 90.0% and that in improving ECG figure was 93.3% in the treatment group, both were significantly higher than those in the control group, 73.4% and 70.0% respectively (P<0.05). The Karnofsky Performance Status scores of heart function were increased and the Activity of Daily Living scores in living capacity decreased in both groups, but the improvements were better in the treatment group (P<0.01 and P<0.05). The parameters of cardiac function, including cardiac output, stroke volume, cardiac index and ejection fraction, were increased in both groups, but the increments in the treatment group were more significant (P<0.01 or P<0.05).
CONCLUSIONLong-term application of SMC could effectively prevent and treat angina pectoris, improve the living capacity and accelerate the recovery of heart function in patients after myocardial infarction.

OBJECTIVETo explore the feasibility and efficiency of extracting protein from bone tissue using trichloroacetic acid (TCA)-acetone precipitation method.
METHODSHydrochloric acid (HCL) decalcification method and TCA-acetone precipitation method were separately used for bone protein extraction. The efficiencies of these two methods were compared.
RESULTSTCA-acetone precipitation method had significantly higher extraction efficiency. Compared with HCL decalcification method, it had less pollution from bone marrow hematopoietic tissue. Protein band distribution was similar between these two methods.
CONCLUSIONTCA-acetone precipitation method is useful for bone proteomics research.

OBJECTIVETo investigate the construction of the green fluorescent protein (GFP) labeled recombinant adenovirus containing human stem cell leukemia (hSCL) and its distribution and efficiency in mice with interstitial cells of Cajal (ICC) loss.
METHODSThe recombinant adenovirus Ad-GFP/SCL was constructed by Ad-Easy system based on the homologous recombination in bacteria, then 1.6 x 10(9) PFU of recombinant adenoviruses were injected into Balb/c mice with ICC loss via the tail vein. In vivo distribution and efficiency of recombinant adenoviruses mediated hSCL were observed by GFP under the fluorescent microscope at different phases. The expression of SCL gene was measured by RT-PCR method. The damages were observed in different organs by HE staining.
RESULTSThe recombinant adenovirus containing hSCL was quickly constructed by homologous recombination in bacteria using Ad-Easy system. Under the fluorescent microscope, GFP was revealed in heart, lung, liver, spleen, kidney, small intestine and large intestine of mice with ICC loss at different phases. No obvious damages were observed in various visceral organs by HE staining. RT-PCR showed SCL mRNA expression in various visceral organs at different levels.
CONCLUSIONSConstruction of adenovirus vector by the homologous recombination in bacteria is an efficient and time saving method, and a high titer of adenovirus is able to mediate the safe and stable expression of SCL gene in mice with ICC loss. This finding will make further gene therapy in mice with STC possible.

OBJECTIVESlow transit constipation (STC) is a colonic motor disorder whose etiology remains unclear. Recent studies have demonstrated a crucial role for interstitial cells of Cajal (ICC) in regulation of intestinal motility. The aim of this study was to examine the distribution of ICC within the normal sigmoid colon and STC patients.
METHODSTwelve patients with STC and eight age-matched controls were studied. ICC were identified with a monoclonal antibody to c-kit by an indirect immunofluorescence method. Immunostained tissues were examined with a laser scanning confocal microscope and the area occupied by ICC was calculated with image analysis software.
RESULTSICC were located in the external muscle layers including longitudinal muscle (LM), myenteric plexus (MP), circular muscle (CM) and submucosal border (SMB). Two types of Kit-positive ICC were observed: bipolar cells characterized by one or two long processes, and multipolar cells with long stellate processes extending in various directions. A higher percentage of ICC was present in the MP regions and CM layers compared with the SMB and LM layers. Tissues from STC patients showed considerably decreased in number of ICC located in the four regions (ICC-LM, ICC-MP, ICC-CM, ICC-SMP), especially for ICC-SMP, almost completely disappeared.
CONCLUSIONDecreased c-kit + ICC in number may play an important role in the pathophysiology of STC. It remains to be determined whether loss of ICC is primary or secondary to another lesion.

OBJECTIVETo investigate clinical effects of auricular acupoint (AA) in the treatment of analgesia during perioperative period in total hip arthroplasty.
METHODSFrom March 2008 to August 2010, 60 patients with late osteonecrosis of the femoral head were treated by total hip arthroplasty and randomly divided into auricular acupuncture (AA) group and control group, 30 patients in each group. There were 11 males and 19 females in the AA group,with an average age of (60.93 +/- 5.90) years; the patients were treated with auricular acupuncture on the point of Shenmen, Subcortex, Kidney and hip joint for four times a week. There were 12 males and 18 females in control group, with an average age of (59.87 +/- 6.21) years; while the patients without auricular acupuncture. VAS score was used to evaluat the degree of pain; Harris score was used to evaluat the function of hip joint. All patients received patient controlled analgesia pump (PCA) for 48 hours after surgery (400 ml liquids were in PCA pump, including 800 mg tramadol and 0.8 mg fentanyl). The dosage of liquids and adverse reaction of PCA pump in different time were recorded.
RESULTSThe VAS score on the 3rd, 4th, 5th and 7th day separately was (3.61 +/- 0.29), (3.59 +/- 0.30), (2.97 +/- 0.26), (2.29 +/- 0.45), and lower than control group, which separately was (4.19 +/- 0.28), (4.00 +/- 0.31), (3.15 +/- 0.29), (2.83 +/- 0.31). The dosage of PCA in AA group separately was (72.27 +/- 8.06), (60.40 +/- 8.16), (44.13 +/- 4.75), (40.40 +/- 3.69), and less than control group, which was (86.27 +/- 8.51), (73.87 +/- 8.32), (54.53 +/- 5.20), (44.67 +/- 6.31) on the time of 0-12, 12-24, 24-36 h and 36-48 h after surgery. During the using of PCA, nausea and vomiting occurred in 5 cases, less than control group (21 cases). Harris score in AA group (78.90 +/- 5.14) was higher than control group (73.37 +/- 5.99) 2 weeks after operation.
CONCLUSIONAuricular acupuncture can reduce postoperative pain, reduce the usage of analgesic and complications, such as nausea and vomiting, improve the function of hip joint after operation.
