Medical Students of modern society are undergoing the change of idea of value.Core value is the core of value system.Therefore,the writer discussing on "Core Value of Medical Students" is to build a harmonious socialist society and to make a rapid development for the medical cause.It is also a unshirkable task of teachers in higher education institutions.

Humanity quality is the needs of people at present and in the future.The humanity quality of the students of medical sciences university is relatively backward because of the facts of history、tradition、society and reality.The writer tries to approach the current situation、cause and ways to settle thoseproblems.

Objective:To observe the curative effect of modified amniotic membrane transplantation for agricultural pterygium.Methods: A total of 276 cases (276 eyes) with early pterygium were randomized divided into traditional group (138 cases) and modified group (138 cases) as random table. The traditional group was treated with pterygium excision in combination with autologous conjunctival transplantation; the modified group was treated with modified amniotic membrane transplantation; to observe the curative effect of the two groups.Results: After all of patients were followed up for 1 year, 122 cases were cured and 16 cases were recurrence, and the recovery rate was 88.41% in traditional group; 131 cases were cured and only 7 cases were recurrence, and the recovery rate was 94.93% in modified group and was better than traditional group; the difference between the two groups was statistical significant (x2=5.02,P<0.05).Conclusion: The modified amniotic membrane transplantation method is simple in operation, mini invasive for eye tissue, and can retain conjunctival tissue in utmost; it also can improve success rate of surgery and be an effective mean for treatment of pterygium.

Objective To compare the efficacy of spectral CT imaging and 64 slice CT in assessment of carotid artery atherosclerotic plaque.Methods Thirty-eight patients with carotid plaque were detected retrospectively in this study (plaque,n=46) by using spectral CT.The composition of atherosclerotic plaque was measured by iodine-based images,lipid-based images with spectral CT imaging.Intraplaque hemorrhae,lipid components were also evaluated on spectral CT imaging and compared with pathology and specimen.Statistical comparison was performed with the Kappa value,independent-sample t test and exact test.Results The degree of carotid artery stenosis was (63.3 ±3.1)％ on spectral CT imaging whereas (61.6 ± 3.8) ％ on 64 slice CT.Two imaging modalities were in good consistency in evaluation of the degree of stenosis (Kappa=0.993,P＜0.01).There was no statistical difference in detecting fibrous cap rupture on spectral CT imaging and 64 slice CT (12 plaques vs 11 plaques,respectively,P＞0.05).Furthermore,spectral CT imaging showed 11 plaques within intraplaque hemorrhage,however,no case was found on 64 slice CT (P＜0.05).The plaque iodine concentration were (6.365 ± 1.937) and (1.573 ±0.776) mg/cm3 with or without internal hemorrhage(t=16.39,P＜0.05).Spectral CT imaging showed 9 plaques within intraplaque liquid whereas only 2 plaques showed intraplaque liquid on 64 slice CT (P＜0.05).Twenty-eight plaques within calcification in the plaque were found on spectrl CT imaging and 27 on 64 slice CT(P＞0.05).Conclusion Spectral CT imaging is a reliable tool in detecting intraplaque hemor-rhage and liquid component.

OBJECTIVE To investigate the infection status and drug resistance of Ureaplasma urealyticum(Uu) and Mycoplasma hominis(Mh) in local region.METHODS A total of 2042 genitourinary samples of NGU patients were detected for the presense of mycoplasma with culture and drug sensibility.RESULTS From them 881(43.1%) were infected with mycoplasma,including Uu infection(650cases,31.8%),Mh infection(74 cases,3.6%) and mixed infection of Uu plus Mh(157 cases,7.6%);significant differences of positive cultivation rate were found between the male and female and in different age groups.Among 18 antibiotics,the lowest resistance drugs were josamycin,doxycycline and clarithromycin(3.6%,4.1%,and 4.2%).The highest resistance drugs were ofloxacin,fleroxacin and thiamphenicol(38.2%,18.3% and 14.6%).CONCLUSIONS The infection of mycoplasma in local region is increasing.Mycoplasma has increasing resistance to the common antibiotic.The detection of drugs resistance of mycoplasma has an improtant significance in guiding clinical use of the drugs.

AIM: To investigate the protective effects of ulinastatin on the rats with paraquat-induced acute lung injury and its mechanisms .METHODS:The Wistar rats ( n=108 ) were randomly divided into control group , pa-raquat group and ulinastatin group .The rats in paraquat group and ulinastatin group were given paraquat by gavage , while the rats in control group were given sterile saline by gavage .The rats in ulinastatin group were also given ulinastatin treat-ment.The serum levels of MDA, SOD, IL-6, IL-10 and TNF-αwere measured after 1 d, 3 d, 7 d, 14 d, 21 d and 28 d. The expression levels of p 38 MAPK, MMP-2 and TIMP-1 in the lung were also measured .RESULTS:The levels of SOD in 1 d, 3 d and 7 d in paraquat group and ulinastatin group were significantly lower than those in control group ( P<0.01).The level of SOD in ulinastatin group was significantly higher than that in paraquat group (P<0.05).The levels of MDA, IL-6, IL-10 and TNF-αin 1 d, 3 d and 7 d in paraquat group and ulinastatin group increased compared with con-trol group (P<0.01), and those in ulinastatin group were significantly lower than those in paraquat group (P<0.05). The levels of p38 MAPK and TIMP-1 in 1 d, 3 d, 7 d, 14 d, 21 d and 28 d in paraquat group and ulinastatin group were higher than those in control group (P<0.01), and those in ulinastatin group was significantly lower than those in paraquat group ( P<0.05) .The level of MMP-2 in 1 d, 3 d, 7 d, 14 d and 21 d in paraquat group and ulinastatin group increased compared with control group (P<0.01), and that in ulinastatin group was significantly lower than that in paraquat group (P<0.05).CONCLUSION:Ulinastatin protects the lung tissues of rats from paraquat-induced acute lung injury by in-hibiting p38 MAPK signaling pathway and ameliorating inflammatory and oxidative responses .

Objective: To investigate the effect of scalp point-through-point acupuncture on 200 kDa neurofilament protein (NF-200) in rats with acute cerebral infarction and explore its mechanism on nerve plasticity in cerebral infarction rats. Methods: Healthy male Wistar rats were randomly allocated to sham operation (Group A), model (Group B) and acupuncture (Group C) groups. A rat middle cerebral artery occlusion (MCAO) model of cerebral ischemia was made. NF-200 mRNA was measured by reverse transcriptase polymerase chain reaction (RT-PCR) in each group on the 7th, 14th and 28th days. Results: The cerebral expression of NF-200 in group C was significantly different from those in groups A and B (P＜0.05); there was a significant difference between groups C and B or A at different time windows (P＜0.01),indicating that scalp point-through-point acupuncture could improve the cerebral expression of NF-200. Conclusion: Scalp point-through-point acupuncture can improve neural function,promote the recovery of limb function and increase the expression of NF-200 after cerebral ischemia, exerting a regulative effect on neuronal plasticity in the brain.

Objective To observe blood gas analysis of internal carotid artery and internal jugular vein to calculate the cerebral extraction of oxygen, and to investigate the relationship between oxyhemoglobin in internal jugular vein, cerebral extraction of oxygen, and the prognosis of patients with head injury. Method Seventy patients with acute severe head injury in ICU of Taizhou People Hospital were studied, and another 80 patients with mild head injury were enrolled as controls. Twenty-four hours after first aid such as keeping airway open and circulatory and ventilation support, and emergency craniotomy, the blood samples from internal carotid artery and internal jugular vein were collected for blood gas analysis including SaO2, PaO2, SjvO2, PJVO2 > PaCO2, PJVCO2, SaO2-SjvO2, Pa-jvCCO2, CaO2-CjvO2 and Ca-jvO2/CaCO2 (CEO2, cerebral oxygen extraction). Results There were significant differences in SjvO2, PjvO2, Sa-jvO2, Pa-jvO2 Ca-jvO2 and CEO2 between two groups. Conclusions The SjvO2 and CEO2 represent the cerebral oxygen uptake and oxygen consumption precisely, and they can be used to predict the outcome of patients with severe craniocerebral trauma commendabiy.
