Objective To investigate the relationship between the serum ghrelin level and β-cell function after treatment of patients with newly diagnosed type 2 diabetes mellitus.Methods 34 patients with newly diagnosed type 2 diabetes mellitus were divided into three groups of pre-treatment(DM0),two weeks after treatment(DM1)and six months after treatment(DM2).Intravenous glucose tolerance tests(IVGTT)were performed and blood glucose,HbA1C,ghrelin,insulin were measured during the study.Insulin sensitivity was assessed by homeostasis model assessment(HOMA).Results(1)Compared with DM0 group,beta-cell function and the mean AUC of insulin were dramatically improved in groups of DM1 and DM2(all P<0.05).(2)Compared with DM1 and DM2,ghrelin levels and the mean AUC of ghrelin in DM0 groups were lower(all P<0.05).(3)Only positive correlation between ghrelin and HOMA-β(r=0.446,P<0.05),and negative correlations of ghrelin with glucose(r=-0.274,P<0.05),insulin(r=-0.35,P<0.05)and BMI(r=-0.276,P<0.05)were found after six months of treatment.Conclusions Ghrelin might play an important role in the pathogenesis and progress of type 2 diabetes mellitus.

Objective To explore the clinical significance of osteopontin (OPN) in systemic lupus erythematosus (SLE) and its pathogenic role in SLE by studying the correlation between OPN and clinical manifestations,laboratory parameters and disease activity.Methods The enzyme-linked immunosorbent assay(ELISA)was used to measure the level of OPN in serum of 68 SLE patients and 20 healthy controls.the clin-ical data and laboratory parameters were recorded.Results The positive rate of OPN was 79.41%in 68 SLEpatients and could not be detected in healthy controls.Compared with healthy controls.the positive rate and level of OPN in SLE patients was significantly higher(P＜0.01).There was no significant difference in age.gender and disease duration between OPN positive and negative lupus patients(P＞0.05).The Drevalence of fever,hair loss,WBC decrease,liver damage,serum C4 decrease,proteinuria and anti-dsDNA antibody in OPN positive SLE were significantly higher than those of OPN negative SLE(P＜0.05).The positive rate of serum OPN in SLE patients was significantly higher than that of anti-dsDNA antibody and anti-Sm antibody (P＜0.01).The level of plasma OPN was associated with systemic lupus erythematosus disease activity index (SLEDAI)(r=0.292,P＜0.05).The positive rate and level of OPN in active SLE patients was significantly higher than that of inactive SLE patients(P＜O.05).Conclusion The level of plasma OPN has a close rela-tionship with the activity of SLE.It may serve as an active disease marker of SLE.

Objective To observe the effectiveness of Chinese herbal medicine plus movement therapy in treating upper limb spasticity in hemiplegic patients. Methods Sixty-six patients were divided randomly into two groups. Thirty-five patients in the therapy group were treated with Chinese herbal medicine and movement therapy, and 31 patients in the control group were treated with movement therapy alone. The modified Ashworth scale and sur- face electromyography were applied to evaluate spasticity. Results The total effectiveness rates were 94.3% in the therapy group and 64.5% in the control group. After treatment, the average integrated electromyogram (IEMG) val- ue in the therapy group was lower than that in the control group. The difference in IEMG values before and after treat- ment in the therapy group was significantly larger than in the control group. Conclusion Chinese herbal medicine plus movement therapy is more effective than movement therapy alone in relieving spasticity.

Objective To study radiation -induced lung damage after lung ionizing radiation and the temporal and spatial release of pro -inflammatory cytokines of interleukin -6(IL-6),interleukin-8(IL-8) and interleukin-10(IL-10)in the irradiated lung tissue.Methods BALB/C male mice weighted around 25 g were randomly divided into two groups:radiation group ( R) and control group ( C) ,with 30 mice in R group and10 mice in C group.The thorax of mice was irradiated by 6 MV X-ray with 25 Gy in 5 fractions.The mice were sac-rificed at 12 weeks post irradiation.Lung tissues were collected and embedded in paraffin .After HE staining,lung histopathological changes were detected by immunohistochemistry to detect IL -6,IL-8 and IL-10 expression in lung tissue.Results Immunohistochemistry results showed that the expressions of IL -6,IL-8 and IL-10 were mainly expressed in macrophages and inflammatory cells .The results showed that the expressions of IL -6 and IL-8 in R group were significantly higher than that in C group .IL-10 expression level was lower than C group.Conclusion After 12 weeks exposing to radiation ,cytokines of IL-6,IL-8 and IL-10 in lung tissue are associated with radiation -induced lung injury .

Objective To detect the expression of serum soluble E?cadherin(sEC)before and after operation in breast cancer patients,and to ex?plore its clinical significance. Methods The levels of sEC in 42 patients with breast cancer and 18 patients with benign breast diseases were tested by enzyme?linked immunosorbent assay(ELISA)before and after operation as well as in 30 healthy controls. Its correlation with clinical and patho?logical characteristics was analyzed. Results The levels of sEC in breast cancer patients before operation were significantly higher than patients with benign breast diseases and controls,which declined significantly after operation. Moreover,the levels of sEC in those with high clinical grading and lymphatic metastasis were also higher than in the ones with low grading and negative lymphatic metastasis(P<0.05). Conclusion The levels of sEC in breast cancer patients before operation are specific and closely related with pathological grade and lymphatic metastasis,which may be a pre?dictive factor for prognosis of breast cancer.

Objective: To explore the effect of apelin on angiotensin II (Ang II)-induced cardiomyocyte hypertrophy and intracellular signal transduction mechanism in experimental rats.
Methods: The cardiomyocyte from 1 to 3 days neonatal rats were cultured with Ang II to induce the cardiomyocyte hypertrophy, and the cells were treated by apelin at different concentrations. The [3H] Leucine incorporation, cardiomyocyte surface area and total protein expression were analyzed to evaluate the degree of cardiomycyte hypertrophy. The protein expressions of intracellular BNP, β-MHC, nuclear factor 3 of activated T cells (NFATc3), calcineurin, phospho-calcineurin, calmodulin kinase II (CaMK II) and phospho-CaMK II were assessed by Western blot analysis. The mRNA expressions of BNP andβ-MHC were examined by RT-PCR.
Results: Apelin may inhibit Ang II induced cardiomyocyte hypertrophic response in a dose-dependent manner, the maximum inhibition was achieved at Ang II 1000 nmol/L. Meanwhile, apelin may inhibit Ang II-induced elevations of intracellular resting free calcium level, mRNA expressions of BNP andβ-MHC, protein expressions of NFATc3, phospho-calcineurin, CaMK II and phospho-CaMK II in a dose-dependent manner.
Conclusion: Apelin may inhibit Ang II-induced cardiomyocyte hypertrophy in experimental rats which might be related to Ca2+-dependent calcineurin signal pass ways.

BACKGROUND: Linxian County of China is one of the areas with the highest incidence of esophageal cancer and gastric cardia cancer in the world, and nutrition-deficiency is widely existing in local people. In recent years, many researches around the world revealed that the cause of Parkinson disease (PD) is related to factors of gene, age, environment, diet, nutrition and smoking. More and more studies confirmed that primary hypertension may be in relation to vascular Parkinsonism (VP) and long-term hypertension was apt to VP.OBJECTIVE: To investigate the relationship between hypertension and clinical probable Parkinson disease (PPD) in nutrition-deficient population of Linxian County and provide a theoretical basis for early prevention and treatment of PD.DESIGN: Cross-sectional study.PARTICIPANTS: A total of 4 335 subjects aged over 55 years were selected. These subjects have taken part in the nutritional intervention study of Linxian County and first entered in the cohort study in 1985. They were enrolled in the nutritional intervention study in Linxian County in 1985.METHODS: A prospective cohort study was conducted. ①Case screening: PD questionnaire (used in American Gebai County) combined with general neurological examination were adopted. ②The diagnosis of PD: Clinical diagnostic criteria of UK Parkinson Disease Society Brain Bank were taken as the criteria for screening PD. Further evaluations were undertaken for clinical PPD and clinical possible PD on subjects who had PD symptoms.The diagnostic criteria of clinical PPD: Subjects were diagnosed as having clinical PPD if they presented any two of the following two cardinal features (resting tremor, hypermyotonia, bradykinesia and impairment of postural reflexes) or presented any one of the following features (resting tremor, hypermyotonia and bradykinesia). Diagnostic criteria of clinical possible PD: Subjects were diagnosed as having clinical possible PD when presented any one of the following four cardinal features (resting tremor, hypermyotonia, bradykinesia, and impairment of postural reflexes).③Definition of hypertension: Hypertension was defined as the systolic blood pressure (SBP) ≥ 140 mm Hg or the diastolic blood pressure (DBP) ≥ 90 mm Hg. Data were processed with linear trend test and nonconditional logistic regression.MAIN OUTCOME MEASURES: Status of final diagnoses on patients and relationship between hypertension and clinical PPD.RESULTS: A total of 4 335 subjects including 2 008 males (46.32%)and 2 327 females (53.68%) participated in the screening of PD.①Results of final diagnosis on patients: Among all the 4 459 survival participants,46 subjects were diagnosed as having PD, 118 as having clinical PPD and 78 as having clinical possible PD. After excluding patients with PD or clinical possible PD, only 118 patients were diagnosed as having clinical PPD. These patients and 4 217 normal controls were analyzed and a total of 2 035 patients had hypertension. ②There were statistical correlation between hypertension and clinical PPD, RR was 1.648 (1.147-2.638), which was 1.668 (1.145-2.432) after being adjusted by possible confounding factors including age, gender, smoking, drinking and so on, the association mentioned above still existed (χ2=7.463,P=0.006). Analysis of gender showed statistically significant differences between female patients with hypertension and clinical PPD(χ2=9.669 P=0.002), and RR before adjust ment was 2.347 (1.347-4.091), which was 2.346 (1.327-4.150) after being adjusted and correlation still existed. While there were no statistical corre lations between male patients with hypertension and clinical PPD (χ2 =0.697 ,P=0.404)but there was also an ascending trend in RR value. ③ With the blood pressure increasing, the RR value correspondingly in creased with the linear trend test (χ2=11.325 ,P=0.003). And there was sta tistical significance in raw and adjusted RR value of hypertension with the BP ≥ 140/90 mm Hg. Respective statistics of SBP and DBP showed a dose-response relationship between SBP and clinical PPD; When the SBP ≥ 140 mm Hg, there were statistical significances in values of raw RR or adjusted RR of hypertension (χ2=8.007 ,P=0.018). While there were no sta tistical significances in RR values before and after adjustment of DBP (χ2 =2.569,P=0.227). CONCLUSION: Hypertension is one of the risk factors of clinical PPD in female residents older than 55 and the incidence of getting clinical PPD is increased with the heightening of BP.
