Postoperative ileus (POI) is a common abdominal postoperative complication of surgery as well as obstetrics and gynecology. There is a lack of an effective method of modern medicine due to its complex pathophysiological mechanism and the postoperative physiological disorder of patient. Acupuncture has remarkable regulatory effects on gastrointestinal function. Some clinical studies indicated that acupuncture was an effective method to treat POI, which could reduce the duration of POI and the treatment costs of patients in hospital. However, the mechanism and law of acupuncture on treating POI is still unclear. Some clinical studies indicated that the regulatory effect of acupuncture on the gastrointestinal motility was associated with its regulation of the autonomic nerve system and immune system. Based on its effect on regulating autonomic nerve system and immune system, acupuncture would be a potential and safe treatment for POI.

OBJECTIVETo compare therapeutic effects between unilateral decompression technique only and open decompression technique with fusion and internal fixation for the treatment of lumbar spinal stenosis.

METHODSFrom March 2008 to February 2011, 82 patients with lumbar spinal stenosis were treated with operations, and divided into two groups. There were 13 males and 19 females in group A, with a mean age of (56.31±4.31) years old. The patients in group A were treated with unilateral decompression via fenestration technique only, including 23 patients obtaining single level decompression and 9 patients obtaining two levels decompression. In group B, there were 18 males and 32 females, with a mean age of (57.53±4.28) years old. The patients in group B were treated with open decompressive technique with fusion and internal fixation, including 38 patients obtaining single level decompression and 12 patients obtaining two levels decompression. The VAS of back pain and leg pain, ODI were recorded before and after surgery to evaluate low back pain,leg pain and walking tolerance.

RESULTSAll the patients were followed up, and the duration ranged from 10.9 to 43.4 months,with a mean of 32.8 months. There were no differences in age, stenosis level, VAS of back and leg pain and ODI before surgery between two groups. Compared with the corresponding ones in group B, the operation time, blood loss, hospitalization time,recovery time of routine daily life and finacial expenditure of patients were all shorter or less in group A. There was no statistically difference in complications between two groups.

CONCLUSION"Unilateral decompression via fenestration technique" is a less invasive and more effective decompressive technique for degenerative spinal stenosis without posterior elements damage. It has advantages in operation time, blood loss, hospitalization time, recovery to daily life and financial expenditure. When controlling the operative indications strictly, the technique could be an important procedure for surgical treatment of degenerative spinal stenosis, especially in the elderly population.

Objective To investigate the killing effect of polymethylmethacrylate (PMMA) on spinal metastasis of transplanted VX2 carcinoma in experimental rabbit models. Methods Spinal metastasis of transplanted VX2 carcinoma model was successfully established in 18 rabbits. The experimental rabbits were randomly and equally divided into three groups with 6 rabbits in each group. Under CT guidance , PMMA or saline was injected into the center of VX2 tumor; in group A 0.3 ml of PMMA was used, in group B 0.1 ml of PMMA was used and in group C (control group) 0.3 ml saline was used. Twenty-four hours after the injection, the animals were sacrificed. Four tissue samples were obtained from the sites at 1 mm , 5 mm, 10 mm and 15 mm away from the PMMA mass in each rabbit of group A and group B , while four tissue samples were collected from different four sites from the tumor ’s center to border in each rabbit of group C. TdT-mediated dUTP nick-end labeling (TUNEL) method was used to determine the tumor cell apoptosis rate. Results After successful establishment of rabbit model, injection of PMMA was performed in sixteen among the eighteen rabbits. Technical success rates were 83.3% in both group A and B, and the success rate was 100% in group C. The difference in technical success rate was not significant. The mean tumor cell apoptosis rates of spinal VX2 carcinoma at 1 mm, 5 mm and 10 mm away from the PMMA mass in group A were (65.75±18.81)%, (50.00±14.24)% and(14.95±8.98)% respectively. The mean apoptosis rate in the control group was (9.79 ±5.24)%; the differences between the group A and the control group were statistically significant (P<0.05). The mean tumor cell apoptosis rate of spinal VX2 carcinoma at 15 mm away from the PMMA mass in group A was (10.30 ±8.13)%, which was not significantly different with that of the control group. The mean tumor cell apoptosis rates of spinal VX2 carcinoma at 1 mm and 5 mm away from the PMMA mass in group B were (49.20±15.57)% and(17.75±9.28)% respectively, which was significantly different with that of the control group(P<0.05); the mean tumor cell apoptosis rates at 10 mm and 15 mm away from the PMMA mass in group B were not significantly different with those of the control group. Statistically significant differences in the mean tumor cell apoptosis rates determined at 1 mm, 5 mm and 10 mm away from the PMMA mass existed between group A and group B(P<0.001). Conclusion PMMA can promote the apoptosis of tumor cells, properly increasing the injected amount of PMMA can enlarge the extent of tumor cell apoptosis.

0.05).The different tilt angles impacted patients' fear psychology(?2=8.038,P=0.018).The order of the extent of children's fear psychology represented from low to high at the angle of 60?,70? and 80?,respectively.The extent of the children's fear psychology had positive correlation with the tilt angle(r=0.669,P=0.002).Conclusions The tilt test angle does not affect the positive rate of HUTT and the hemodynamics in children undergoing HUTT with angles from 60? to 80?.The children at the tilt angle 60? had less fear than at the angle of 70? or 80?.The 60? tilt angle of HUTT in children is recommended in the clinical practice.

AIM:To make a survey on people suffering trachoma in Gansu province, and to provide evidence for developing trachoma control and prevention therapy.
METHODS: We chose the zone on the basis of relative information. Provincial Office of Blindness Prevention carried out the survey in 3 counties including Tange Township of Wushan, Xiqu Township of Minqin and Hulinjia Township of Jishishan from October 14, 2013 to November 23, 2013. One hundred and fifty primary school students were selected, including 72 boys and 78 girls aging from 5a to 10a with the average age of 7. 5y. The targeted students received the fast trachoma assessment by the adoption of simplified trachoma classification system which was recommended by the World Health Organization.
RESULTS: No case of active trachoma, trachomatous trichiasis and corneal disease were examined among 150 students.
CONCLUSION: The rate of trachoma is low in Gansu province. But we still cannot get the conclusion that there is no epidemic of trachoma in Gansu. And we need to further expand the survey scope to correctly assess the trachoma case and to provide reliable evidence for trachoma prevention and control.

Trachoma, a contagious keratoconjunctivitis ( KC ) , caused by Chlamydia trachomatis infection, is rife in 57 countries in the world at present. The World Health Organization ( WHO) listed the global alliance to eliminate blinding trachoma by 2020 as one of top priorities of its blindness prevention in 1998. A simplified classification system for identifying and naming trachoma, designated by WHO, and the SAFE strategy based on community intervention were extended continuously in the world in 10 years since then. The trachoma prevalence trend has showed a change compared with that in the past. China has launched the blindness prevention action, aimed to eliminate blinding trachoma by 2016. In this paper, we reviews progress in diagnosis, treatment and epidemic of trachoma since the extension of the SAFE strategy.

BACKGROUNDPostural orthostatic tachycardia syndrome (POTS) is a common clinical problem in children and adolescents. The previous diagnostic approach to POTS of children and adolescents is based on a series of tests to exclude all other causes, which is time and medical resource consuming. Recently, a new diagnostic approach has been developed. The present study was designed to statistically analyze the results of clinical investigation items and the cost for the diagnosis of POTS in children patients, and evaluate cost changes in the diagnosis of POTS.

METHODSA total of 315 children patients were divided into two groups according to diagnosis period, including group I diagnosed in 2002 - 2006 (100 cases) and group II in 2007 - 2010 (215 cases) and the diagnostic item-based distribution of the cost was analyzed. The diagnostic costs were compared between two groups using SPSS17.0.

RESULTSThe per-capita cost of diagnosis in group I was (621.95 ± 21.10) Yuan, costs of diagnostic tests (head-up tilt test, standing test, etc) accounted for 8.68% and the exclusive tests for 91.32%. The per-capita cost of diagnosis in group II was (542.69 ± 23.14) Yuan, diagnostic tests accounted for 10.50% and exclusive tests for 89.50%. Comparison of the total cost of diagnostic tests between the two groups showed significant differences (P < 0.05).

CONCLUSIONThe cost of POTS diagnosis has been declined in recent years, but the cost of exclusive diagnosis is still its major part.

OBJECTIVETo detect the expression of fibroblast activation protein(FAP) in colorectal cancer tissue, and to investigate the association between expression of FAP with pathological parameters.

METHODSFifty-five cancer tissues and 50 normal colorectal samples were examined using immunohistochemistry with anti-FAP polyclonal antibody. The distribution of positive cells in different tissues, and associations of positive cell number with tumor staging, lymph node metastasis and tumor invasion were investigated to evaluate the effects of FAP on pathological progress in colorectal cancer.

RESULTSNo FAP expression was observed in 50 normal colorectal tissue samples. FAP positive cells were seen in carcinoma associated fibroblasts(CAFs), and in few colorectal cancer cells. The numbers of FAP positive cells in tissue samples of TNM III(-IIII((40.1±15.9) was significantly greater than that of TNMI(-II( (18.3±7.7)(P<0.01). Furthermore, the number of FAP positive cells in tissue samples with lymph node metastasis (44.4±13.3) was also significantly higher than those without lymph node metastasis (18.5±8.1)(P<0.01). Significant positive correlations were found between the number of FAP-positive cells with the tumor TNM staging and lymph node metastasis(r=0.544 and r=0.793, respectively)(P<0.01). The number of FAP-positive cells was 25.2±8.9 in T2, 32.41±19.30 in T3, and 29.2±16.5 in T4. The association between number of positive cells and depth of invasion was not statistically significant(P>0.05).

CONCLUSIONSThe FAP mainly expresses in CAFs locating in colorectal cancer tissues. The number of FAP positive cells is positively correlated with TNM staging of colorectal cancer and lymph node metastasis.
