Objective:
To investigate the effectiveness of horticultural therapy on improving university students mental health problems and to provide evidence to support the application of horticultural therapy in the prevention and treatment of university students mental health.
Methods:
From March to May 2022,a before-and after paired design was used with a blank control group, mental health screening abnormalities were recruited from a comprehensive university in Hebei Province, including 57 in the intervention group and 21 in the control group, and the Symptom Checklist-90(SCL-90) score and hair cortisol were included as outcome indicators, which was measured by enzyme linked immunoassay Elisa double antibody sandwich method.
Results:
The total SCL-90 scores of the intervention group decreased ( t=4.28, P <0.01) and were significantly lower compared with the control group( t=-2.66, P <0.01), while no significant difference was observed in the control group( t=0.29, P >0.05), and the difference between the pre and post measures on each dimension of the SCL-90 was significantly lower in the intervention group (all P <0.01); the difference between the pre and post measures of hair cortisol contentration in the intervention group was statistically significant( Z= -2.75, P <0.05), and the hair cortiso contentration in pre measure group was lower than that of control group( Z=-3.48, P < 0.01 ). In contrast, the difference between pre and post measurements of hair cortisol in the control group was not significant( Z= -0.75 , P >0.05).
Conclusion
Horticultural therapy can improve the psychological symptoms of university students is suitable for psychological interventions in the university population and is beneficial to the health and well being of university students.

OBJECTIVETo investigate the clinical application of 256 multi-slice spiral computed tomography angiography (MSCTA) technique in the preoperative evaluation of mesenteric angiography in order to provide a reference to vessel anatomy and dissociation in laparoscopic radical operation for colorectal carcinoma.
METHODSClinical data of 50 patients with colorectal cancer who underwent preoperative MSCTA+FDCT and laparoscopic curative operation at our hospital from October 2013 to March 2015 were collected (MSCTA group). The evaluation item was visualization of mesenteric artery, which was compared with the findings under laparoscopic surgery. Meanwhile, another 50 colorectal cancer patients undergoing laparoscopic radical operation by the same surgeon team without preoperative MSCTA examination were used as control(control group). Clinical data were compared between the two groups.
RESULTSMSCTA precisely and correctly demonstrated anatomy and variations of the mesenteric artery and relative nutrient vessel in carcinoma. The angiography reconstruction images were consistent with the visual anatomy and variation from laparoscopic findings, whose diagnostic conformity rate of 100%. As compared to control group, operative time was shorter [(195.0±23.2) minutes vs.(218.0±19.6) minutes, t=8.326, P=0.015], and blood loss was less[(168.1±18.8) ml vs. (206.5±14.3) ml, t=-19.369, P=0.002] in MSCTA group. Differences of number of harvested lymph node, postoperative complication morbidity, postoperative hospital stay and hospitalization cost were not significant between two groups(all P>0.05).
CONCLUSIONPreoperative MSCTA can demonstrate anatomy and variations of the mesenteric artery precisely and correctly, thus it is beneficial to shorten the operation time and to reduce blood loss.

The eye-computer interaction technology based on electro-oculogram provides the users with a convenient way to control the device, which has great social significance. However, the eye-computer interaction is often disturbed by the involuntary eye movements, resulting in misjudgment, affecting the users' experience, and even causing danger in severe cases. Therefore, this paper starts from the basic concepts and principles of eye-computer interaction, sorts out the current mainstream classification methods of voluntary/involuntary eye movement, and analyzes the characteristics of each technology. The performance analysis is carried out in combination with specific application scenarios, and the problems to be solved are further summarized, which are expected to provide research references for researchers in related fields.
