To explore therapeutic efficacy of androgens and low dose all-trans retinoic acid (ATRA) for myelodysplastic syndrome (MDS) patients, 55 patients of MDS were observed, including 41 cases of refractory anemia (RA), 11 cases of refractory anemia with excess of blasts (RAEB), 2 cases of refractory anemia with excess of blasts in transformation (RAEB-t) and 1 case of chronic myeloic-monocytic leukemia (CMML). These patients received danazol (600 mg/day) or stanazol (6 mg/day) and ATRA (10 mg/day) for at least 3 months. The results showed that according to MDS international working group response criteria, at the end of three months,complete remission (CR) was seen in 1 patient, partial remission (PR) was found in 2 patients. Hematologic improvement: major response (MaR) were seen in 15 patients, minor response (MiR) were seen in 4 patients. The total response rate was 35.8%. In conclusion, danazol or stanazol in combination with low dose ATRA are partialy effective in therapy for patients with low-risk myelodysplastic syndrome.

To explore the role of regulatory peptides in the secretion of bronchial epithelial cells (BECs), we observed the effects of four peptides, i.e.vasoactive intestinal peptide (VIP), epidermal growth factor (EGF), endothelin-1 (ET-1), and calcitonin gene-related peptide (CGRP), on the secretion of ILs from unstimulated or O3-stressed BECs. The results of the experiments showed that VIP exerted an inhibitory effect on the secretion of IL-1 and IL-8 from unstimulated and O3-stressed BECs, VIP also decreased the secretion of IL-5 from O3-stressed BECs; EGF promoted secretion of IL-1 and IL-8 from unstimulated BECs, but decreased the secretion of ILs from O3-stressed BECs; ET-1 and CGRP enhanced the secretion of IL-1, IL-5, and IL-8 from unstimlated BECs, CGRP also increased the secretion of ILs from O3-stressed BECs. The results obtained demonstrate that intrapulmonary regulatory peptides modulate the secretion of ILs from BECs, and may play an important part in transduction of inflammatory signals.

OBJECTIVETo investigate the relationship between the distribution of mononucleotide polymorphism of five regulation regions of alpha-IFN among HLA-DRB1*11 gene episodes and the therapeutic effects of alpha-IFN treatment in chronic hepatitis B patients.

METHODSOne hundred seven chronic hepatitis patients from Nanjing Second Hospital who were treated by alpha-IFN for 12 months and then followed at least six months without the treatment were randomly selected for this regressive analysis. They were grouped into a continuous responsive group and a non-continuous responsive group. Hepatitis B virus X interacting protein gene locus was searched in NCBI. Single nucleotide polymorphism (SNP) gene locus was detected based on a pooling sequencing method. Primer and TaqMan-MGB probes referring to different mononucleotide loci were designed respectively to detect SNP in five regulation regions of alpha-IFN. Then gene sequencing differences between the two groups were analyzed.

RESULTSAmong the 107 cases there were 30 cases (28.0%) in the continuous responsive group and 77 cases (71.9%) in the non-continuous responsive group. CT occupation rate in five regulation regions of IFN reached 18.0% in the continuous responsive group and 23.8% in the non-continuous responsive group. AG occupation rate reached 10.8% in the former group and 15.8% in the latter group. The differences in CT and AG between the two groups were significant.

CONCLUSIONSThe distribution of mononucleotide polymorphism of five regulation regions of alpha-IFN among HLA-DRB1*11 gene episodes affects the IFN anti-virus treatment. Detecting the gene distribution of mononucleotide in five regulation regions of alpha-IFN helps in predicting the therapeutic effects of alpha-IFN.

Objective The proto-oncogene c-Met was found to express on human laryngeal carcinoma Hep-2 cell line in previous research. In the present study, the author further examined whether inhibition of c-Met by RNA interference(RNAi) might inhibit biologic activity of Hep-2 cell line in vitro and proliferation using a murine laryngeal carcinoma model. Methods RNAi plasmid that can express small interfering RNA targeting c-Met or siRNA that did not match any known human coding mRNA( control siRNA plasmid) was designed,constructed,and transfected into Hep-2 cell line by using cationic liposome Lipofectamine2000 as transfecting agent. In vitro, the transfection efficacy was tested by RT-PCR and Western Blot method, then elected the most inhibitive c-Met-siRNA sequence. Cell proliferation, movement and invasion were studied using MTT, cell migration assay and cell invasion assay, respectively. The Hep-2 cells were transplanted into nude mice, then the time of tumor formation and growth were observed. After tumor formation, c-Met-siRNA was given as the anti-tumor therapy. Expression of c-Met, MMP-9 and VEGF were detected by Western Blot method. Results After the pSilencer2. 0/c-Met-shRNA recombinant plasmid transfeetion into laryngeal carcinoma Hep-2 cells, the expression of mRNA and proteinum of c-Met decreased significantly in Hep-2 cells. On the 35th day after tumor vaccination, the tumor volume was (138±27)mm~3 in c-Met-siRNA transfection group, Which was diminished significantly in contrast with control group( P<0. 01 ). The expression of c-Met, MMP-9 and VEGF in the tumor of experiment group was decreased significantly, respectively (P<0.05 ). Conclusions The results indicated that c-Met-siRNA can down-regulate the expression of c-Met and markedly inhibit laryngeal carcinoma Hep-2 cell proliferation, movement and invasion and the growth of transplantation tumor of nude mice. The siRNA expressing plasmid mediated gene therapy might be a new strategy in targeting molecular therapy of cancer of larynx.

OBJECTIVETo evaluate the early and midterm outcomes of carotid endarterectomy (CEA) compared with carotid stenting (CAS) in patients with carotid artery stenosis.

METHODSA prospective randomized single-center clinical trail to compare with endarterectomy and stenting in patients with symptomatic carotid stenosis of at least 50% and asymptomatic stenosis of at least 70%. From May 2004 to December 2006, there were 40 patients who agreed with the treatment were randomly assigned to undergo either CEA or CAS. The primary end point was any stroke or death within 30 d after treatment and the secondary end point was any stroke, myocardial infarction and any complications of the treatment, or death or ipsilateral stroke and carotid restenosis between 1 month and 18 months, and the cost-effectiveness of both groups were analyzed retrospectively as well.

RESULTSThere were no significant differences of the characteristics in the two groups. Twenty cases in CEA group underwent 23 endarterectomies (3 cases had bilateral CEA, respectively), in which 9 carotid shunt (39.1%) and 12 patching (52.2%) were used. Twenty cases in CAS group underwent 23 stents (3 cases had bilateral CSA, respectively), in which 21 emboli-protection devices (91.3%) were used. There was no significant difference in 30 d neurological complications (4.3% vs. 8.7%), acute myocardial infarction (4.3% vs. 0), and wound hematoma (8.7% vs. 0) between CEA and CAS, respectively. There was no ipsilateral transient ischemic attack or carotid restenosis at 18 months in each group. The average cost of hospitalization was (16 450.95 +/- 6188.76) vs. (70 130.15 +/- 11 999.02) RMB in CEA and CAS, respectively, with significant difference (P < 0.01).

CONCLUSIONThe early and midterm outcomes are no significant difference between CEA and CAS, but in China, the cost of hospitalization in CAS is much higher than that of CEA.

OBJECTIVETo study the role of c-Jun N-terminal kinase (JNK) signal transduction pathway in the course of asthma airway remodeling, to explore whether IL-1beta participates in asthma airway remodeling mediated by JNK signal transduction pathway.

METHODSTotally 72 male Sprague-Dawlay rats (6 - 8 weeks old, weighing about 120 g) were randomly divided into control groups (36 rats) and asthma groups (36 rats). The rats were sensitized for inducing asthma by intraperitoneal injection of ovalbumin and AL(OH)3 and were repeatedly exposed to aerosolized ovalbumin for 4, 8, 12 weeks (A4, A8, or A12 group), each had 12 rats, and correspondingly control rats were intraperitoneally injected with 0.9% NaCl, then were repeatedly exposed to 0.9% NaCl for 4, 8, 12 weeks (C4, C8, or C12 group), each had 12 rats. The ultrastructural changes of pulmonary tissues were observed by transmission electron microscope (TEM). The total bronchial wall thickness (Wat) and the airway smooth muscle thickness (Wam) were measured by an image analysis system. The concentrations of IL-1beta in serum and bronchoalveolar lavage fluid (BALF) were tested by a "sandwich" ELISA. The protein expressions of P-JNK and P-c-Jun were detected by immunohistochemical technique. Lung tissue extracts were analyzed for phosphorylation of JNK by Western blotting. Linear correlation analysis showed the correlation between Wat and P-JNK protein, Wam and P-JNK protein, levels of IL-1beta in serum and P-JNK protein, levels of IL-1beta in BALF and P-JNK protein.

RESULTSIn asthma groups, TEM showed alveolar septal proliferation and alveolus type II epithelial cells swelling. Wat and Wam in all asthma groups were significantly higher than those in corresponding control groups (P < 0.01, respectively), and compared with group A4 and group A8, Wat and Wam of group A12 significantly increased (P < 0.01). The concentrations of IL-1beta in serum and BALF of asthma groups were all significantly higher than those of the corresponding control groups (P < 0.01, respectively), and compared with group A4 and group A8, the concentrations of IL-1beta in BALF of group A12 significantly increased (P < 0.01 or P < 0.05), but the levels of IL-1beta in serum were not significantly different among them (P > 0.05). Mean absorbance values (by immunohistochemistry) of P-JNK and P-c-Jun in asthma groups were significantly higher than those in corresponding control groups (P < 0.01, respectively), and compared with group A4 and group A8, those of group A12 significantly increased (P < 0.01 or P < 0.05). The absorbance (by Western Blot) of P-JNK in A4, A8, A12 group was significantly higher than that in C4, C8, C12 groups (P < 0.01, respectively), and compared with group A4, that of P-JNK of A12 significantly increased (P < 0.01), and compared with group A8, there was no significant difference (P > 0.05). Strong positive correlations were found between Wat or Wam and P-JNK (r = 0.823 and r = 0.818, P < 0.01, respectively, n = 68) and between P-JNK and concentration of IL-1beta in serum or BALF (r = 0.717 and r = 0.803, P < 0.01, respectively, n = 68).

CONCLUSIONSThe expression of P-JNK and its downstream P-c-Jun in rats of asthma airway remodeling is increased, which implicates that JNK signal transduction pathway plays an important role in the course of asthma airway remodeling. IL-1beta participates in asthma airway remodeling possibly partly through activating JNK signal transduction pathway.
