The university students must promote themselves to become persons with sound personality in order to adapt to the society request for talents.But the university students experience emotion burnout and the deviation of development in mental and behavior during the period full of variety and surging.So the education of sound personality should be placed in the higher education to raise the university student's comprehensive character.

Objective To investigate the effect of different maturation methods on mitochondrial functions of oocytes and the possible mechanism. To explore novel ideas for developing assisted reproductive technology (ART). Methods Female mice were used as models and randomly allocated into three groups, COH, IVM and NC control. Oocytes maturated with different methods which were all simulated with those treatments in human IVF cycle. Immunofluorescence were used to measure the mitochondrial membrane potentials and analyze the cy-toskeleton. Results The mitochondrial membrane potential in the COH group was significantly lower than that in NC group and IVM group (P < 0.05). The proportion of normal cytoskeleton including spindle structure and chromosome configuration in the COH group and IVM group were significantly lower than that in the NC group (PCOH < 0.01, PIVM < 0.05). Conclusions Both COH and IVM can affect mitochondrial functions.

Objective To explore the effects of Irbesartan on the plasma concentrations of lysophosphatidic acid(LPA), endothelin-1(ET-1),serum concentration of nitric oxcide (NO) in the patients with acute cerebral infarction(CI).Methods All of the 53 patients were randomly assigned to Irbesartan therapy group(n=25) treated with Irbesartan 150 mg/d and Aspirin 100 mg/d and conventional therapy group(n=28) treated with Aspirin 100 mg/d.Both groups were treated for 14 days and the other measures of symptomatic therepy were the same. And another 23 patients without cerebrovascular diseases and 7 health volunteers were taken as control group.The venous blood samples were taken for measureing the levels of LPA,ET-1,NO while the scorces of neurological deficit (NDS)were evaluated before and after treatment. Results (1)Before treatment the levels of LPA,ET-1 in CI group were significantly higher and the level of NO was significantly lower than that in control group (all P

Objective: To analyze the sagittal and vertical skeletal an d dental changes contributing to correction of Class Ⅱ division Ⅰ malocclusion and mandibular retrusion in growing children treated with Herbst appliance. Method: 27 cases of Class Ⅱ division 1 malocclusion were studied, 17 of them were treated with the domestic Herbst appliance and the other 10 case s without treatment served as the controls. Results: After 6 to 8 months (on an average of 7 months) of Herbst appliance therapy, Class II malo cclussion was corrected to Class I occlussion, overjet decreased by 7.2 mm on a n average. SNB, mandibular ramas height (Co-Go), mandibular length (Co-Pg), ma ndibular body length (Go-Pg) and the distance from Pg to OLP plane increased si gnificantly(P

Aim To investigate the relationship between spinal cord noradrenergic neurons ? 1 adrenoceptors and the spinal analgesia of ketamine. Methods Kunming mice were used. Analgesia tests were investigated with warm water tail flick test. The effects of intrathecal injection (ith) of ketamine (50,100,200 ?g)on tail flick latency of animals were observed. And the effect of pretreatment with intrathecal 6 hydrodoapa(6 OHDA, 6?g ) and ? 1 adrenoceptor antagonist prazosin (5, 15 ?g) or terazosin (5, 15 ?g) , respectively on the spinal analgesia of ketamine (100 ?g,ith) was studied. Results Dose dependent analgesia was observed following ith ketamine (100,200 ?g, P

Objective To explore the effect of the prenatal dexamethasone treatment on the preventionof wet lung syndrome in the newborn of elective caesarean section at term. Methods Two hundred cases of elective caesarean section at term (the gestation age was less than 39 weeks) were divided into observation group and control group,with 100 cases in each by random digits table. Observation group was treated with four intramuscular injections of 6 mg dexamethasone in the 24 hours to 7 days before delivery, and control group was treated with 0.9% sodium chloride injection with the same method. The clinical data and the incidence of the wet lung syndrome of the newborn were collected. Results The incidence of the wet lung syndrome of the newborn was 1%(1/100) in observation group and 9%(9/100) in control group,and the incidence of the severity of the wet lung syndrome of the newborn was 1% ( 1/100) in observation group and 2%(2/100) in control group. There were no complication in observation group and 1 case in control group.The incidence and the severity of the wet lung syndrome of the newborn in observation group were less than that in control group significantly (P = 0.009,0.049). Conclusion Prenatal dexamethasone treatment can reduce the incidence of the wet lung syndrome of the newborn and decrease the incidence of the severity and complication of elective caesarean section at term.

Objective To evaluate the guiding role of capsule endoscopy (CE) in choosing the access route of double-balloon enteroscopy (DBE) for small bowel diseases. Methods Patients with complete CE and with small bowel diseases confirmed by DBE were enrolled. The lesion location found on CE was represented by the time index, which was the ratio of access time from pylorus to lesion over access time from pylorus to ileocecal valve. Based on our previous retrospective evaluation, oral approach was selected when the index was ≤0. 6, otherwise the anal access would be chosen. Accuracy of time index predicting DBE access rout was evaluated. Results Data of 60 patients undergoing both CE and DBE were evaluated. All lesions detected by CE were confirmed by DBE, with 41 via oral route and 19 via anus. Based on the time index with threshold of 0.6, the accuracy of selecting the insertion route of DBE was 100%. Conclusion DBE is an effective approach to confirm CE results. In patients with complete small bowel investigation by CE, the insertion route for DBE can be reliably indicated with time index based on the CE results.

Objective To determine the detection rate of duodenal papilla and the diagnostic rate of small bowel diseases by capsule endoscopy(CE)and its possible influencing factors.Methods A total of 369 cases with suspected small bowel disease who had undergone CE were retrospectively reviewed. The de- tection rate of duodenal papilla and that of small bowel disease were calculated respectively. The detection rate of duodenal papilla in another 369 patients having received gastroscopy was also counted in order to findout the miss detection rate of forward-viewing endoscopy. The CE findings were reviewed at the rate of 1 im-age and 15 images per second by hand-motion respectively. The detection rate of duodenal papilla was calcu-lated,and the number of frames showing duodenal papilla was counted. Differences of detection rate of duo-denal papilla were also analyzed by different age and gender groups. In addition,the potential difference in detection rate of duodenal papilla between different bowel preparations before CE of two different reviewing approaches was also investigated respectively. Results The miss detection rate of duodenal papilla with for-ward-viewing gastroscopy was 22. 0%. The detection rate of duodenal papilla reviewed at the rate of 1 image by hand-motion,where less frames were needed to visualize duodenal papilla(3. 7vs7. 0),was significantly higher than that at the rate of 15 images per second(32. 2%vs13. 6%,P=0. 001). The diagnostic rate of small bowel diseases was also significantly higher than that of duodenal papilla by CE(67. 2%vs32. 2%,P=0. 000). Age and gender were not significantly correlated with the detection rate of duodenal papilla. No significant correlation was found between various kinds of bowel preparation before CE at different viewing rate and the detection rate of duodenal papilla. Conclusion It iS relatively difficult to identify duodenal pa- pilla by CE,as they are peculiarly positioned in anatomy,so the detection of duodenal papilla does not nec- essarily represent the detection rate of small bowel diseases. The major factors that influencing the detection of duodenal papilla by CE include local anatomy,viewing rate and technical limitations of CE.

Objective To evaluate the use of spiral enteroscopy in diagnosis and treatment of smallbowel diseases.Methods The data of 8 patients who underwent spiral enteroscopy from July to September 2009 were retrospectively studied.The variables including maximal insertion depth,total procedure time,complications,and outcome were evaluated.Results The average maximal depth of intubation was 2.2 m beyond the Ligament of Triez (0-3.6 m beyond Ligament of Triez),with a mean procedure time at 41 min (25 to 77 min).Small bowel Crohn's disease was diagnosed in 2 cases with biopsy suggesting active inflammation and granular formation.Small intestinal tumor was detected in 1 patient with pathological finding of high grade dysplasia.Jejunal ulcer was detected in 1 patient.Multiple polyps were found in 1 patient after jejunal anastomosis,which were then treated with endoscopic argon plasma coagulation (APC).No abnormalities were found in 3 other patients.No complications occurred during and after the procedure.The maneuver of spiral enteroscopy and APC were same as that of balloon enteroscopy.Conclusion Spiral enteroscopy is simple and convenient to operate,which is of great potential in clinical use.
