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 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 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

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 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 evaluate the clinical effect of capsule endoscopy(CE)followed by a directed double-balloon enteroscopy(DBE)in diagnosis of patients with suspected small bowel disease.Methods Two hundred and ninety-nine consecutive patients with obscure gastrointestinal bleeding or other various indications for CE examination were analyzed.DBE was recommended after negative or indeterminate evaluation on CE.The diagnostic and follow-up data were collected and analyzed.Resails A total of 296 patients completed CE examination.Of whorn,138(46.6%)cases had positive findings,68(23.0%)cases were suspected for small bowel disease and 90(30.4%)cases had negative finding,Those who were suspected(45 cases)and negative(7 cases)for CE examination were performed DBE examination and small bowel lesions were found in 31 cases and 1 case,respectively.The false-negative diagnosis was probably made by DBE in 8 patients,whereas no false-positive case was found by DBE.The false-negative diagnosis was probably made by CE in 2 patients,whereas 8 false-positive cases were found by CE.With the results of CE examination,lesions were found by only one-side procedure of DBE in 90.3%(28/31)of patients.The results that followed up for median 17 months indicated that 93.5% of patients with positive findings by DBE were received optimal therapy.Both CE and DBE procedures were well tolerated and no severe complications occurred.Conclusions The detection rate of sinall bowel lesions with CE was high,whereas the indetermination of CE findings was also significant.Majority of suspected findings by CE may be further confirmed by DBE.The strategy that start with CE and followed by DBE may increase diagnostic yield in patients with suspected small bowel disease and improve the prognosis.

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.

Objective To discuss the clinical value of immunofecal occult blood test in screening of colorectal cancer and its precancerous lesions in a large series of health checkup population. Methods Colorectal cancer and its precancerous lesions in 5919 subjects undergoing health checkup in our hospital were screened out by using immunofecal occult blood test from July 2006 to June 2007; positive cases with the test were subjected to colorectal endoscopy or X-ray barium enema examination. Relevant results were analyzed in combination with clinical and pathological data. Results Positive result was obtained in 314 out of the 5919 subjects undergoing health checkup with immunofecal occult blood test; the positive rate was 5.30%. 241 cases(76.75% )of them accepted colorectal endoscopic examination and 23 cases(7.32%) accepted X-ray barium enema examination. The total follow up rate was 84.08% with 50 cases out of contact. After excluding the cases out of cantact, 16 cases of colorectal cancer were found morbidity 2.37‰ including 8(50.00% )cases of Dukes A,7 cases (43.75%)of Dukes B and 1 case of Dukes C (6 .25%).The detection rate of colorectal cancer with postive imunofecal occult blood test was 6.06% (16/264). 94 cases (16.01‰) of adenomatous polyps were found including 55 cases (58.51%) of tubular adenoma, 23 cases (24.47% )of villiform- tubular adenoma and 16 cases(17.02%) of villfform adenoma. Among these cases 55 (58.51%)were solitary and 39(41.49%) multiple. In addition, 6 cases of ulcerative colitis in active phase were found. Altogether 116 (43.94%)of the 264 cases with positive immunofecal blood test and not out of contact were found to have colorectal cancer or its precancerous lesions. Conclusion Immunofecal occult blood test is suitable for screening of colorectal cancer and its precancerous lesions in large series of population. Colorectal cancer and its precancerous lesions may be found in relatively early phase and be eradicated in curable stage, thus to reduce the morbidity and mortality.
