ObjectiveTo investigate the correlation between serum C-reactive protein(CRP),tumor necrosis factor-alpha(TNF-α) and atherosclerosis in patients with subclinical hypothyroidism.Methods Seventy-five patients with subclinical hypothyroidism were divided into two groups according to the level of TSH:mild group (42 cases) with TSH between 5.5 and 10.0 mU/L and severe group (33 cases) with TSH ＞10.0 mU/L.Thirty healthy physical examinees or volunteers were selected as control group.TG,LDL-C,HDL-C,TSH,FT4,FT3,CRP,TNF-α and carotid intima-media thickness(CIMT) of all cases were detected and measured.ResultsCIMT of mild,severe and control groups were(0.88 ± 0.20),( 1.12 ±0.21 ),(0.62 ±0.21 ) mm,respectively.CIMT of mild and severe groups were both significantly higher than that of control group,CIMT of severe group was significantly higher than that of mild group (P ＜ 0.01 ).There were no significant differences of CRP and TNF- α among three groups (P ＞ 0.05 ).LDL-C of mild and severe groups were significantly higher than that of control group [ (3.22 ± 0.37),(3.49 ± 0.38 ) mmol/L vs.(2.48 ±0.41 )mmol/L,P ＜0.01 ].HDL-C and TG between mild and control groups had no statistical significance (P ＞0.05).Compared with control and mild groups,HDL-C of severe group decreased [(0.92 ±0.10)mmol/L vs.( 1.21 ± 0.14),( 1.17 ± 0.11 ) mmol/L] and TG increased [ ( 1.50 ± 0.49) mmol/L vs.( 1.11 ±0.53),(1.27 ±0.47) mmol/L](P＜ 0.01 or ＜ 0.05).The levels of TG,LDL-C,TSH,CRP and TNF-α had positive correlation with CIMT (r =0.52,0.37,0.48,0.39,0.45;P ＜0.05 or ＜0.01 ).FT4 was negatively correlated with CIMT (r=-0.24,P＜0.05).HDL-C had no relation with CIMT (r =0.06,P ＞0.05).ConclusionsThere are many abnormalities such as metabolism disorder of blood lipid in patients with subclinical hypothyroidism.The risk of atherosclerosis increases in these patients and inflammatory reaction may not be an important factor of subclinical hypothyroidism complicated with atherosclerosis.

OBJECTIVETo observe the clinical effect of electric stimulation of long-term retaining needle on analgesia after laparoscopic cholecystectomy (LC) and the impacts on the post-surgical flatus time.

METHODSUnder static absorptive composite general anesthesia, 90 cases of LC were randomized into three groups, 30 cases in each one. In the control group, the analgesia was not applied after LC. In the analgesia-pumper group, the patient controlled intravenous analgesia (PCIA) was used. In the needle-retaining group, the electric acupuncture stimulator was used. The needles were inserted transversely at Riyue (GB 24), Qichong (ST 30) and Yanglingquan (GB 34) and fixed with sterile sticker. Separately, in 8 h and 24 h after surgery, the electric acupuncture stimulation with disperse-dense wave, 2 Hz/100 Hz frequency was applied continuously for 30 min. Visual analogue scale (VAS), adverse reactions such as vomiting and nausea and the postoperative flatus time in 2, 4, 8, 12, 24 and 36 h after surgery were observed and recorded in the three groups.

RESULTSIn 2, 4, 8, 12 and 24 h after surgery, VAS scores in the needle-retaining group and the analgesia-pumper group were all lower than those in the control group (P < 0.05, P < 0.01). The analgesia effect at the above time points in the needle-retaining group was better than that in the analgesia-pumper group (all P < 0.05). There was not adverse reaction in the needle-retaining group. But there were 3 cases of somnolence, 6 cases of nausea and 3 cases of vomiting in the analgesia-pumper group, and 2 cases of nausea and 1 case of vomiting in the control group. The flatus time was quite earlier in the needle-retaining group as compared with the other two groups [(14.77 +/- 4.99) h vs (18.50 +/- 4.22) h, P < 0.01; (14.77 +/- 4.99) h vs (18.17 +/- 4.69) h, P < 0.05].

CONCLUSIONThe electric stimulation of long-term retaining needle is safe and effective in analgesia after LC. It avoids the adverse reactions of analgesics and promotes postoperative flatus.

OBJECTIVETo describe the clinicopathologic features and immunophenotypes of carcinoid tumorlets in the lung with bronchiectasis, and to study the morphogenesis of these tiny tumors.

METHODSThe histopathologic characteristics of 3 bronchiectasis cases with carcinoid tumorlets, 11 bronchiectasis and 2 normal lungs were studied. Specific markers of the tiny tumors and the number of neuroendocrine cells (NECs) in the airway mucosa were immunohistochemically detected by EnVision method.

RESULTSThe tumorlets in the lungs presented as multi-focal nodules and most were displayed only under microscopy. These cells were arranged in clusters and foci of fascicles which were situated in the surrounding bronchial wall and bronchioles adjacent to bronchiectatic lesion, or in the scar tissues. The tiny tumors were consisted of short fusiform cells and small ovoid cells. Their nuclei were circular, oval or long fusiform and the cells were strongly argyrophilic on Grimelius staining. Intensive positive immunostaining for calcitonin, chromogranin A, NSE and gastrin were detected. Weak positive for CK, EMA, S-100 and focal positive for HC, ACTH, 5-HT were also observed. Proliferative NECs in airway mucosa adjacent to the tiny tumors increased significantly in number, compared with those in the airway mucosa of bronchiectasis without tumorlets and normal lungs (P < 0.001, respectively).

CONCLUSIONSThe clinicopathologic features and immunophenotypes of carcinoid tumorlets resemble carcinoid tumors. They are the early stage of carcinoid development. Their development may be related to the chronic pulmonary damage resulting in hypoxia and stimulating the proliferation of NECs. These pulmonary carcinoid tumorlets can be used as a model to study the tumorigenesis of carcinoid carcinoma of the lung.

OBJECTIVETo study osteoblastic phenotype expression of New Zealand rabbit skin fibroblasts transfected with mouse core binding factor a1/osteoblast specific transplanting factor-2 gene (Cbfa1/Osf2).

METHODSCbfa1/Osf2 gene, engineered into eukaryotic expression vector pSG5, was introduced into New Zealand rabbit skin fibroblasts with catholyte liposomes-Lipofectamine 2000. Meanwhile, those transfected pSG5 and un-transfected were set the control groups. The expression of Cbfa1 gene, osteocalcin (OCN) gene, alkaline phosphatase (ALP) gene and pre-peptide 2 alpha gene of collagen type I were detected by RT-PCR assay. Cbfa1 protein was detected by Western-Blot assay, in-cell ALP activity by p-nitrophenyl phosphate (PNPP) assay and OCN content in the supernatant by radio-immunity method. The ossification nodules was detected by Alizarin-Red staining and scanning electron microscope.

RESULTSCbfa 1mRNA and Cbfa1 protein were expressed in New Zealand rabbit skin fibroblasts transfected with pSG5-Cbfa1/Osf2 from the first day to the fifth day, but they were not detected in the control groups. In the pSG5-Cbfa1/Osf2 transfected group, the expression of ALP gene and OCN gene were respectively induced from the third day and the forth day, pre-peptide 2 alpha gene of collagen type I was enhanced from the third day. From the sixth day, ALP activity greatly increased, OCN strongly secreted, and they were maintained at a high level for about 4 weeks, and the difference was significant compared with the control group (P < 0.05). On the forty-second day, ossification nodules were found on the surface of pSG5-Cbfa1/Osf2 gene transfected cells.

CONCLUSIONSNew Zealand rabbit skin fibroblasts transfected with pSG5-Cbfa1/Osf2 can express osteogenesis-related genes and proteins, and form ossification nodules on their surface.

OBJECTIVETo compare the prognostic value of B-type natriuretic peptide (BNP) and GRACE score in patients with acute coronary syndrome.

METHODSA total of 246 patients with chest pain to hospital time < 24 hours were followed up to 30 days. Admission plasma B-type natriuretic peptide was measured by point-of-care. Endpoints included death, reinfarction, recurrent ischemia and new onset of congestive heart failure. The receiver operating characteristic (ROC) curve was used to evaluate prognostic value of BNP and GRACE score. The logistic regression models were used to assess the prognostic contribution of BNP level and GRACE score.

RESULTSThe mean age was (67.6 +/- 12.0) years (61.8% males) and ST elevation myocardial infarction (STEMI) was diagnosed in 135 patients (54.9%). During the follow up, 34 endpoints (13.8%) were recorded including 9 deaths (3.7%). The systolic blood pressure [(121 +/- 29) mm Hg vs. (130 +/- 23) mm Hg, P = 0.034; 1 mm Hg = 0.133 kPa] was significantly lower while the heart rate and plasma creatinine were significantly higher in the endpoints group than in non-endpoints group. TNI and CRP levels were similar between the two groups. The BNP level at admission (median 883.5 ng/L vs. 216.5 ng/L) and GRACE score (median 164.5 vs. 142.0) were significantly higher in the endpoints group than in non-endpoints group (all P < 0.05). The prognostic criteria for BNP level (area under cure, 0.704) was 194.5 ng/L determined by ROC (P = 0.043). For GRACE score, the predictive value for endpoints was 0.742 (P = 0.003) and the cut-off point was 158. In the logistic regression model, BNP concentration (> 194.5 ng/L, OR = 3.174) and GRACE score (> 158, OR = 4.031) were independent predictors of endpoints in patients with ACS.

CONCLUSIONBoth BNP level at admission and GRACE score were independent predictors for endpoints at 30 days in patients with ACS.
