Objective To evaluate the effect of consecutive diet nursing intervention on elderly patients with type 2 diabetes. Methods 56 elderly type 2 diebetes patients were randomly selected in control group and were given conventional type 2 diabetes management. The other 56 patients in experimental group were not only given routine care, but also 3 months of consecutive diet nursing intervention. At the 1st and 3rd month, assessment of blood glucose test and quality of life were conducted by all patients conducted. T test, chi-square test were used in the statistics. Results In experimental group, the controlling effect of fasting plasma glucose and 2-hour postprandial blood glucose have been significantly improved. 3 months after the consecutive diet nursing intervention, fasting plasma glucose of control and experimental groups were (7.18±0.89) mmol/L and (6.37±0.74) mmol/L (P=0.027). After 1 months of the consecutive diet nursing intervention, 2-hour postprandial blood glucose of control group and the experimental group were (11.69 ± 1.58) mmol/ L and (9.03 ± 2.13) mmol/ L (P = 0.028) respectively. After 3 months of intervention, the number were were (12.12±2.36) mmol/L and (8.36±1.65) mmol/L respectively (P<0.01). In the experimental group, the therapeutic dimension of quality of life has been gradually decreased and the difference was statistically significant. Conclusions Consecutive diet nursing intervention can effectively improve the blood glucose control of elderly type 2 diabetes patients.

ObjectiveTo investigate the relationship between HLA-DRB1 alleles and chronic urticaria with positive autologous serum skin test (ASST) in Guangxi Zhuang Autonomous Region.MethodsASST was conducted in 144 patients with chronic urticaria,who were subsequently divided into two groups according to the test result:positive group (n =62) and negative group (n =82).PCR amplification with sequence-specific primers was used to determine the genotypes of HLA-DRB1 alleles in the patients and 199 normal human controls.Chi-square test was performed to analyse the difference in the frequency of HLA-DRB1 alleles between the 3 groups by using the SPSS 13.0 statistical software package.ResultsThere were significant differences in the frequency of HLA-DRB1*01,*1401 and *16 alleles among the patients with positive and negative ASST and the controls (x2 =10.92,Pc =0.032;x2 =35.34,Pc ＜ 0.01 ;x2 =12.69,Pc =0.032).Paired comparison revealed significant differences in the frequency of HLA-DRB1*1401 allele between the patients with positive ASST and controls(RR =17.09,Pc ＜ 0.01 ) as well as between the patients with positive and negative ASST (RR =7.20,Pc ＜ 0.01).ConclusionHLA-DRB1*1401 allele may be,or be linked to,the predisposing gene of chronic urticaria with positive ASST in Guangxi Zhuang Autonomous Region.

Obesity is an established risk factor for endometrial cancer. Leptin, a secreted protein of the ob gene by white adipose tissue, plays an important role in the regulation of food intake and energy consumption in the brain and acts as a potential growth stimulator in normal and neoplastic cancer cells. However, a direct role for leptin in endometrial cancer has not been demonstrated. In the present study, the effect of leptin on the proliferation of Ishikawa endometrial cancer cells was investigated as well as the possible mechanism(s) underlying this action in endometrial cancers which express both short and long isoforms of leptin receptors. The expression of leptin receptor (ObRb) in Ishikawa cells was detected by RT-PCR and Western blotting. The cells after serum starvation, were treated by leptin with various concentrations (0, 10, 50, 100, 150 ng/mL) for different durations (6, 12, 24 h). The effect of leptin treatment on cell proliferation was examined by MTT assay. Meanwhile, inhibitory effect of Janus tyrosine kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) inhibitor AG490 or extracellular signal-regulated kinase 1/2 (ERK1/2) inhibitor PD98059 on the proliferation of Ishikawa cells induced by leptin was also studied. Ishikawa cells were treated with 100 ng/mL leptin for various periods (0, 20, 40, 60 min), and the levels of STAT3 phosphorylation and ERK1/2 phosphorylation were examined by Western blotting. The results showed that leptin induced the phosphorylation of STAT3 and the activation of ERK1/2 in a time- and dose-dependent manner in the Ishikawa endometrial cancer cells. Blocking STAT3 phosphorylation with the inhibitor AG490, or blocking ERK1/2 activation by the specific ERK1/2 kinase inhibitor, PD98059, abolished leptin-induced proliferation of Ishikawa cells. In addition, leptin was found to potently induce the invasion of endometrial cancer cells in a Matrigel invasion assay. Leptin-stimulated invasion was effectively blocked by pharmacological inhibitors of STAT3 (AG490) and ERK1/2 kinase (PD98059). These results suggested that leptin promotes endometrial cancer growth and invasiveness by activating STAT3 and ERK1/2 signaling pathways and therefore blocking its action at the receptor level can be a rational therapeutic strategy.

To evaluate the therapeutic effect of hematopoietic stem cell transplantation (HSCT), we performed HSCT in 30 patients with hematologic maligancies. Of the 30 patients, 10 underwent autologous peripheral blood stem cell transplantation (auto-PBSCT), 13 underwent myeloablative allogeneic HSCT while 7 underwent nonmyeloablative allogeneic HSCT, which were designated as autologous group, myeloablative group and nonmyeloablative group, respectively. All patients except the one who underwent cord blood transplantation, were successfully engrafted. Median time for the granulocytes > or = 0.5 x 10(9)/L and platelets > or = 20 x 10(9)/L were 12 days and 13 days respectively in autologous group, 16 days and 19 days in myeloablative group, 15 days and 12 days in nonmyeloablative group. In myeloablative group, acute graft-versus-host diseases (aGVHD) was observed in 3 patients, all of which were I-II grade. Oral mucous cGVHD was observed in 1 patient. In nonmyeloablative group, 1 patient developed intestinal aGVHD grade IV and cutaneous cGVHD was induced by donor lymphocyte infusions (DLI) in 3 patients. 1 patient had hematological relapse in autologous group. 1 patient had cytogenetic relapse in myeloablative group. In nonmyeloablative group 3 patients had cytogenetic relapse and were cured by DLI, 1 patient had hematological relapse. 4 of the 30 patients died of infection (2 patients), grade IV aGVHD (1) and relapse (1) respectively. 26 patients are still alive. 3 years overall survival (OS) and 3 years disease free survival (DFS) were 100% and 64.81% respectively in autologous group, 78.75% and 63% respectively in myeloablative group while both 66.67% in nonmyeloablative group. In conclusion, autologous group had less transplant-related complications and mortality. Active prophylaxis of relapse could significantly promote DFS. The transplant-related mortality limited DFS in myeloablative group. More relapses occurred in nonmyeloablative group, but could be cured by DLI.

OBJECTIVESTo detect aberrant p16 promoter methylation in serum of patients with colorectal cancer (CRC), and to explore the possibility of using this assay in early detection or as a prognostic marker.

METHODSMethylation-specific PCR was used to detect p16 methylation in DNA extracted from 52 CRCs and corresponding serum samples. Serum samples from 34 patients with adenomatous polyps and 10 healthy individuals were used as controls. The association of p16 hypermethylation in serum DNA of CRC patients with clinicopathological characteristics was analyzed.

RESULTSp16 methylation was found in 38% (20 of 52) of CRC tissues. Among the 20 patients with aberrant methylation in the tumor tissues, similar changes were also detected in the serum of 14 (70%) patients. No methylated p16 sequences were detected in the peripheral serum of the 32 CRC patients without these changes in the tumor, in 34 paitents with adenomatous polyps, or in 10 healthy controls. Clinicopathological analysis revealed that p16 methylation in serum was significantly associated with later Dukes' stage (chi(2) = 5.7, P = 0.03).

CONCLUSIONThis assay offers a potential means for the serum-based detection and/or monitoring of CRC patients.

To investigate the expression of mRNA of leptin long-form receptor (OB-Rb) in luteinized granulosa cells of obese women with polycystic ovary syndrome (PCOS), and to determine the role of leptin in the physiopathology of PCOS, luteinized granulosa cells were collected from the follicle fluid of 10 obese women who met the diagnostic criteria for PCOS and their BMI was equal to or greater than 25 kg/m2, and at the same time, granulosa cells were collected from 10 normal women undergoing IVF-ET who served as the control group. Some luteinized granulosa cells were taken from normal women for in-vitro culture, into which human leptin of different concentrations was added (0, 10, 100 and 1000 ng/mL). After stimulation with leptin for 48 h, RT-PCR was employed for the detection of the expression of OB-RLmRNA in the luteinized granulosa cells. Our results showed that the level of OB-RLmRNA in luteinized granulosa cells of obese PCOS women was higher than those in the control (P＜0.05). In luteinized granulosa cells cultured in vitro and stimulated by human leptin for 48 h, the level of OB-RLmRNA was higher than those without leptin stimulation (P＜0.01), and when leptin concentration was at 100 ng/mL, and the level of OB-RLmRNA reached a peak. It is concluded that in obese PCOS women, the level of serum leptin is increased, which promotes the expression of OB-RL in luteinized granulosa cells and increases the sensitivity of the granulosa cells to leptin. Leptin may contribute to anovulation in obese women with PCOS.
