Objective To investigate the changes and clinical significance of serum lactate dehydrogenase (LDH),creatine kinase (CK),glutamate pyruvate transaminase (AST),and cerebrospinal fluid lactate dehydrogenase (CSF LDH) in adult patients with acute central nervous system infection.Methods The levels of myocardial enzymes (AST,LDH,and CK) in serum of 96 adult patients with acute intracranial infection in 7days and 39 healthy people were measured by Beckman automatic biochemical analyzer and enzyme rate assay,and CSF LDH level in 96 patients were measured simultaneously.Results (1) The serum myocardial enzymes (LDH,CK,and AST) of intracranial infection group (47 cases with viral encephalitis,30 cases with tuberculous meningitis,and 19 cases with purulent encephalitis) were significantly higher than those of normal control group (P ＜0.01).(2)The myocardial enzymes (LDH,and AST ) of patients with cerebral functional disorder were significantly higher than those of patients with normal cerebral function (P ＜0.05).(3)The levels of serum AST,LDH,and CK in the virus encephalitis group,serum AST and LDH in the purulent encephalitis group,and serum LDH in the tuberculous meningitis group were significantly higher than those in the control group (P ＜ 0.01).The CSF LDH level in the viral meningitis group was prominently lower than that in the tuberculous encephalitis group and purulent encephalitis group,respectively (P ＜0.01).(4) No correlations were found between CSF LDH and serum myocardial enzymes (P ＞0.05).Conclusions (1)There is significant change in the levels of serum LDH,CK,AST,and CSF LDH of adult patients with acute intracranial infection,especially in infected patients with cerebral functional disorder,and the change of LDH is the most obvious.(2)The levels of serum myocardial enzymes and CSF LDH are helpful to the differential diagnosis of intracranial infection in early stage,and judging the severity of the illness.

OBJECTIVESTo evaluate the effects of varicocele (VC) on IL-1 and NO levels in testes of rats with VC.

METHODSMale adult Wistar rats were divided into two groups randomly, VC group (n = 30) and pseudo-operation group (n = 20), and the levels of IL-1 and NO in the testes were determined and compared.

RESULTSThe levels of IL-1 and No of left tests in VC group were higher than those in pseudo-operation group, respectively(P < 0.01). While the levels of IL-1 and NO of right testes between two groups were not significantly different (P > 0.05). More over, the level of IL-1 correlated significantly with that of NO(r = 0.572, P < 0.01).

CONCLUSIONSThe results revealed that the changes of IL-1 and NO levels in the testes of rats with VC might be the reason which caused testes damage, disturbance of spermatogenesis and even infertility.

Objective To analyze the stage characteristics in the exercise behavior improvement of college students and explore the role of Process in the exercise behavior change based on the transtheoretical model, providing basis for the stage-matched intervention for the exercise behavior of college students. Methods There were 932 students who completed the questionnaires, from 5 universities in Shanxi Province were selected by using a stratified random cluster sampling method. Descriptive analysis was used to describe the exercise behavior of college students. Variance analysis and multivariate Logistic regression model were used to analyze the difference of the process of with stage of change among college students’ physical exercise. Multivariate variance analysis was used to analyze how personal characteristics affect process of change. Results Among all participants, 89.4% students knew the importance of physical exercise, and 29.4% students were satisfied with their physical exercise condition. The distribution of students’ physical exercise stage showed an inverted U-shape with left-side peak, and there was a significant difference between gender( 2=54.657, P<0.001). There were significant stage characteristics in the process of students' exercise behavior, gender had a significant main effects on mutual aid relation(F=7.400, P=0.07)and conscious control (F=7.778, P=0.005), gender and grade had interaction effects on social release (F=3.614, P=0.013). Conclusions The college students' exercise behavior showed the characteristics of “knowing but not to do”, which conformed to the Transtheoretical model. It is essential to develop targeted phased exercise intervention strategies according to the relationship between change of phase and change of procedure.

Objectives: To explore the incidence and factors of severe leukopenia and/or thrombocytopenia in newly diagnosed patients with chronic myeloid leukemia (CML) to probe their impacts on cytogenetic and molecular responses, progression free survival (PFS) and overall survival (OS) . Methods: Data of newly diagnosed patients with CML in the chronic phase (CP) and/or accelerated phase (AP) were retrospectively collected and analyzed. Results: 855 CML patients [including 744 (87%) in the CP and 111 (13.0%) in the AP] were included in this study. 523 (61.2%) patients were male with a median age of 39 years (range, 14-87 years) . 749 (87.6%) patients received imatinib, 93 (10.9%) nilotinib, and 13 (1.5%) dasatinib, respectively as front-line therapy. At a median treatment of 1 month (range, 0.1-7.0 months) , 137 (16.0%) developed ≥grade 3 leukopenia and/or thrombocytopenia and recovered 0.6 month (range, 0.3-6.5 months) . Multivariate analysis showed that female gender (OR=1.5, 95%CI 1.0-2.2, P=0.033) , WBC ≥100×10⁹/L (OR=1.9, 95%CI 1.3-2.8, P=0.001) , CP in Sokal high-risk (OR=2.2, 95%CI 1.2-3.9, P=0.005) , AP with ≥15% blast cells in blood or bone marrow (OR=5.1, 95%CI 1.9-13.3, P=0.001) were factors associated with higher incidence of ≥grade 3 leukopenia and/or thrombocytopenia. Severe leukopenia and/or thrombocytopenia with time of drug discontinuance >2 weeks was associated with lower probabilities of achieving complete cytogenetic (OR=0.4, 95%CI 0.3-0.6, P<0.001) , severe leukopenia and/or thrombocytopenia, no matter the time of drug discontinuance >2 weeks or ≤2 weeks, were associated with lower probabilities of achieving major molecular responses (OR=0.3, 95%CI 0.2-0.5, P<0.001; OR=0.7, 95%CI 0.5-1.0, P=0.036) and MR4.5 (OR=0.2, 95%CI 0.1-0.5, P=0.002; OR=0.7, 95%CI 0.4-1.1, P=0.110) ; however, those had no impacts on PFS and OS. Conclusions: Severe leukopenia and/or thrombocytopenia were common adverse events during TKI therapy. Female patients, WBC ≥100×10⁹/L at diagnosed, CP in Sokal high-risk, CML-AP with ≥15% blast cells in blood or bone marrow were at high risk for higher incidence of severe leukopenia and/or thrombocytopenia. Those severe adverse events had impacts on lower cytogenetic and molecular response.

Objective To study the effects of human uriilary kallikrein(HUK)on the number of apoptotic cells and the expressions of Bcl-2 and Bax proteins in rats after focal cerebral ischemia and reperfusion(FCIR) injury. Methods Eighty-four Spmque-Dawley(SD)male rats were randomly divided into sham-operated group(n=12),ischemia-reperfusion group(n=36),and HUK-treated group (n=36). Transient focal cerebml ischemia models were established by middle cerebml artery occlusion.Six rats were chosen from sham-operated group,ischemia-reperfusion group,and HUK-treated group for measuring infarct sizes.The rest were used to evaluate neurologic fhnction impaiment and measure the nunlber of apoptotic cells and Bcl-2 or BaX protein positive cells in cerebral cortex with TUNEL and immunohistochemistry.The latter 2 groups were subdivided into 6,12,24,72,168 h reperfusio groups (each n=6). Results The neurologic function impairmlent score,the infarct sizes,the apoptotic cells and the expression of Bax protein of HUK-treated group at different time points (except 168 h group)significantly decreased compared wilh those of ischemia-reperfsion group (p＜0.05).The expression of Bcl-2 protein of HUK-treated group at different time points(except 168 h group) remarkably increased compared with that of ischemia-reperfusion group(P＜0.05). Conclusions HUK can excrt a protection against FCIR injury, maybe through up-regulating Bcl-2 and down-regulating Bax protein in the initial 3 d of FCIR injury to decrease the number of apoptotic cells

OBJECTIVETo study the effects of the extensive resection of the tumor-loading segment and artificial humerus head replacement combined with perioperative rehabilitation for the treatment of stage II to III giant cell tumor of bone in the proximal humerus.

METHODSFrom March 2007 to March 2010, 7 patients with stage II to III giant cell tumor of bone in the proximal humerus were treated. Among the patients, 3 patients were male and 4 patients were female with a mean age of 34.6 years (ranged, 18 to 49 years). The mean course of disease was 19 months (ranged, 6 to 35 months). All the patients were confirmed to suffer stage II to III giant cell tumor of bone in the proximal humerus by pathology and X-ray examinations. Clinical manifestations of the patients included persistence aggravated pain of the shoulder, swelling in the proximate arm with obviously tenderness, activity limited of the joint. All the patients were treated with extensive resection of the tumor-loading segment and artificial humerus head replacement combined with perioperative rehabilitation. CMS and OSIS score system were used to evaluate shoulder function and shoulder stability.

RESULTSAll the patients were followed up, and the duration ranged from 14 to 35 months, with an average of 17 months. There were no serious complications or recurrence in all cases. One year after the surgery CMS and OSIS score system were 70.7 scores (ranged,63 to 82 scores) and 25.1 scores (ranged, 18 to 29 scores) respectively. According to evaluation for shoulder function, 2 patients got an excellent result and 5 good. According to evaluation of shoulder stability, 1 patient got an excellent result and 6 good.

CONCLUSIONExtensive resection of the tumor-loading segment and artificial humerus head replacement combined with perioperative rehabilitation for the treatment of stage II to III giant cell tumor of bone in the proximal humerus would not only preserve the upper extremity but also preserve the function of upper extremity.
