Objective To observe the effects of intensive insulin therapy on C-reactive protein (CRP) ,interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α ) in the patients of critical illness complicated with hyperglycemia and its incidence of side effect. Methods Two hundred and nine patients of critical illness complicated with hyperglycemia were randomly divided into intensive insulin therapy group (106 patients,blood glucose maintained at a level of 4.4-6.1 mmol/L) and conventional insulin therapy group ( 103 patients, blood glucose maintained at a level of 9.0-11.1 mmol/L). Serum levels of CRP,TNF- α and IL-6 were determined on 0,24,48,72 h respectively after ICU admission. Results The levels of blood glucose of both groups reached the target level. The incidence rates of the hypoglycemia had no significant difference between two groups [6.60 % (7/106) vs. 4.76% ( 3/63 ),P > 0.05]. After 72 h treatment, serum level of CRP in intensive insulin therapy group was significantly lower than that in conventional insulin therapy group (P < 0.05 ). After 24,48 and 72 h treatment, serum level of IL-6 in intensive insulin therapy group was significantly lower than that in conventional insulin therapy group (P < 0.05 ). After 48 and 72 h treatment, serum level of TNF-αin intensive insulin therapy group was significantly lower than that in conventional insulin therapy group (P < 0.05). Conclusion Intensive insulin therapy can significantly decrease the levels of non-specific inflammatory factors in patients of critical illness complicated with hyperglycemia, which brings beneficial effect to the patients.

Objective: To observe the effect of hypoxia on changes of proliferation ability of cultured human periodontal ligament fibroblasts (HPLFS) in vitro. Methods: HPLFS were randomly divided into two groups (experimental group and control group) by different oxygen concentrations. The oxygen concentration of control group was 21%. The oxygen concentrations of experiment group were 10%, 5% and 2%. The proliferation ability of HPLFS was detected by MTT colorimetric assay. The cell ultrastructure was observed by transmission electron microscope (TEM). Results: MTT assay results showed that compared with the control group, at the 12 h and 24 h, cell proliferation was enhanced with the hypoxia degree. At 24 h, cell proliferation showed significant differences. At 48 h and 72 h, proliferation of the cultured HPLFS in severe hypoxia group reduced significantly. Observed by TEM, at 24 h, not only the number of mitochondria, rough endoplasmic reticulum but also cell process increased in the cultured HPLFS in severe hypoxia group. At 72 h, the number of lysosome increased and the cell structure degenerated. Conclusion: Long-time severe hypoxia may lower the repair and remodeling abilities of periodontium, which might be one of the important etiological factors of periodontal disease under condition of high altitude.

Objective: To explore the value of dual energy CT lung perfusion imaging (DEPI) for diagnosing pulmonary embolism (PE) in comparison with CT pulmonary angiography (CTPA). Methods: There were 49 patients with suspected PE received DEPI scanning and 19 with CTPA conifrmed diagnosis were enrolled in this study. CTPA image was obtained by 80 kv data, and DEPI image was obtained by PBV software. The location, type of PE in CTPA image, and the location, shape of perfusion defect in DEPI were observed and compared by segment basis. The correlation and agreement of CTPA and DEPI for diagnosing PE were calculated and the un-agreement was analyzed. Results: A total of 380 segments were included for analysis. CTPA detected 162 segments of PE and DEPI detected 155 segments of perfusion defect or reduction, partial PE were mainly presented by perfusion defects as speckles, patches or without perfusion defect, and complete PE were mainly showed segmental or sub-segmental perfusion defects. CTPA and DEPI were correlated for PE diagnosis (χ2=305.5,P=0.000), the diagnostic agreement was 83.42% and KAPPA value was 0.659. Conclusion: The perfusion defect in DEPI is related to the degree and type of PE presented in CTPA, their combination is helpful for diagnosing PE.

OBJECTIVETo observe the clinical efficacy difference between segmentation scraping and conventional acupuncture for cervical spondylosis (CS) so as to provide effective treatment method.

METHODSEighty-five cases of cervical type of CS were randomly divided into a scraping group (44 cases) and an acupuncture group (41 cases). The segmentation scraping therapy was used in the scraping group. The scraping group was treated with focusing on scraping the head and joint part of neck and occiput in the upper cervical spine injury, and focusing on scraping the lower section of cervical and shoulder in the lower cervical spine injury, once every seven days, totally for 3 times. In the acupuncture group, Fengchi (GB 20),Wangu (TE 5), Tianzhu (BL 10),Neck-Jiaji (EX-B 2), etc. were selected,once daily,for 15 days. The visual analogue scale (VAS) was used to evaluate the immediate analgesic effect after the first treatment and the clinical efficacy was observed after the end of treatment.

RESULTSAfter the first treatment, the score of VAS was decreased significantly in the scaping group (P < 0.01), but there was no significant difference in the acupuncture group compared with those before treatment (P > 0.05); the score of VAS in the scaping group after the first treatment was lower than that in the acupuncture group (3.66 +/- 0.74 vs 5.43 +/- 0.35, P < 0.01). Compared with before treatment, the scores of VAS were decreased significantly after treatment in two groups (both P < 0.01), but without significant difference between two groups (P > 0.05); the effective rate was 95.5% (42/44) in the scaping group and 87.8% (36/41) in the acupuncture group, the curative effects were similar (P > 0.05).

CONCLUSIONBoth of scraping and acupuncture therapies have good analgesic effect for cervical spondylosis, and overall effects are similar, but the immediate analgesic effect of scraping thrapy is better than that of conventional acupuncture.
