Objective:To explore the effects of allergic factors in chronic sinusitis . Method:Skin prick test and specific serum IgE of 194 patients with chronic sinusitis were performed in our department before endoscopic sinus surgery from October,2007 to October,2008, and correla- tion between test results and clinical classification was analyzed retrospectively. Result: ① Result of skin prick test was analyzed. Positive rate of house dust was 20.6% (40/194),of dust mites 16.0%(30/194),of house dust mites 14.9%(29/194). ② Positive rate of allergic specific serum IgE and skin prick test in experimental group was compared with that of control group. Positive rate of house dust mites,dust mites and house dust between groups were significantly different(P<0.05).③ Clinical classification of chronic sinusitis had a negative correlation with the specific serum IgE (house dust mites ,house dust and dust mites)about experimental group(P<0.05). Conclusion: Allergic factors was associated with etiopathoge-nisis and course of disease of chronic sinusitis.

OBJECTIVEThis study explores the effects of different fibrin glue combination modes on the survival, proliferation, and apoptosis of dental follicle cells (DFCs), as well as to evaluate the feasibility and effectiveness of fibrin glue as transplantation material.

METHODSThe membranes of surviving DFCs were marked using 3,3'-dioctadecyloxa carbocyanine perchlorate (DIO), and the cell number was counted by using ImageJ2x software. The apoptotic cells were marked with prodium iodide (PI).

RESULTSCompared with that of the 3D-2 and 2D-1 groups, the degradation speed of the 3D-1 group was the slowest. DFCs could survive and grow well in fibrinogen with a concentration of 15 mg · mL⁻¹ supplemented with thrombin with a concentration of 2 U · mL⁻¹. In particular, the 3D-1 combination mode was significantly conducive to cell proliferation and stretching.

CONCLUSIONFibrin glue can be used as an effective cell transplantation material. The different combination modes have certain effects on cell proliferation. The 3D-1 combination mode is more conducive to the survival and proliferation of DFCs than other modes.

Objective: To observe the clinical efficacy of heat-sensitive moxibustion in intervening acute ischemic stroke. Methods: A total of 112 patients were divided into a control group and an observation group by the random number table method, with 56 cases in each group. The control group was treated with conventional treatment, and the observation group was treated with heat-sensitive moxibustion on the basis of the treatment in the control group. The National Institute of Health stroke scale (NIHSS) and modified Barthel index (MBI) were evaluated, and the intracranial hemodynamic indicators including mean velocity (Vm), pulsatility index (PI) and resistance index (RI) were recorded, and the serum levels of superoxide dismutase (SOD) and homocysteine (HCY) were measured before and after treatment. Clinical efficacy was evaluated after treatment. Results: The total effective rate of the observation group was significantly higher than that of the control group (P<0.05). After treatment, the NIHSS scores in both groups decreased significantly (both P<0.05), and the MBI scores increased significantly (both P<0.05). The improvements of NIHSS and MBI scores in the observation group were superior to those in the control group (both P<0.05). Vm in both groups increased significantly (both P<0.05), PI and RI decreased (all P<0.05), and Vm, PI and RI in the observation group were superior to those in the control group (all P<0.05). The serum levels of SOD and HCY in the observation group were significantly improved, and were statistically different from those in the control group (both P<0.05). Conclusion: Conventional treatment plus heat-sensitive moxibustion is effective in intervening acute ischemic stroke. It can promote the recovery of neurological function, improve daily activities, and improve intracranial blood flow, which may be related to the regulation of serum SOD and HCY levels.

OBJECTIVETo explore the effect of qidong huoxue decoction (QHD) on inflammatory factors and Toll-like receptor (TLR4) mRNA expressions in acute lung injury (ALI) rats.

METHODSTotally 50 healthy male SD rats were randomly divided into the blank control group, the lipopolysaccharide (LPS) model group, low, middle, high dose QHD groups according to body weight, 10 rats in each group. Rats in low, middle, high dose QHD groups were intragastrically administered with QHD at 4, 8, and 16 mL/kg 24, 12 h before modeling and 12 h after modeling, respectively. Normal saline was intragastrically administered to rats in the blank control group and the LPS model group. An ALI rat model was established using intratracheal instillation of LPS. Rats were killed after 24-h modeling. Then the bronchoalveolar lavage fluid was prepared. Contents of TNF-α, IL-1β, and L-10 were detected using ELISA. TLR4 mRNA expressions were determined byreal time PCR.

RESULTSCompared with the blank control group, contents of TNF-α, IL-1β , and IL-10 increased (P <0. 01), TLR4 mRNA expressions also increased in the LPS model group (all P <0. 01). Compared with the LPS model group, contents of TNF-α and IL-1β decreased (P <0. 05, P <0. 01), IL-10 levels increased (P <0. 01) , TLR4 mRNA expressions were also reduced (P <0. 01), in high and middle dose QHD groups. Compared with the high dose QHD group, con- tents of TNF-α and IL-1β increased in middle and low dose QHD groups (P <0. 05); IL-10 levels decreased (P <0. 05) in the low dose QHD group(P <0. 05), TLR4 mRNA expressions also increased in the low dose QHD group (P <0. 05). Compared with the middle dose QHD group, IL-10 levels was reduced, but TLR4 mRNA expressions increased in the low dose QHD group (P <0. 05).

CONCLUSIONSQHD had the protective effect on LPS induced ALI rats. Its mechanism might be associated with inhibiting TLR4 mRNA expressions, leading to decreased pro-inflammatory cytokines such as TNF-α and IL-β, elevated anti-inflammatory cytokine IL-10, and thereby, correcting unbalanced inflammation.

Objective To investigate the inhibitory effect of adriamycin in combination with hyperthermia on apoptosis and bcl-2 expression in the chronic leukemic cell line K562/AO2 in vitro.Methods The working con- centration of adriamycin against K562/AO2 determined by using methyl thiazolyl tetrazolium(MTT) assay was used to treat the chronic leukemic cell line K562/AO2 in vitro alone or in combination with hyperthermia induced using a hot water bath at 40,41 or 42℃.The inhibitory effect was evaluated by MTT assay.The apoptosis rates and bcl-2 ex- pression of K562/AO2 were determined by flow cytometry.Results The working concentration of adriamycin in the study was defined as its 50% inhibition concentration (IC50).A 60 min session of hyperthermia at 40℃,41℃or 42℃was associated with significant growth inhibition of the cell line K562/AO2.Adriamycin chemotherapy alone and with hyperthermia significantly inhibited the growth of K562/AO2.All treatments significantly increased apoptosis rates and down-regulated bcl-2 expression of the K562/AO2 cell line.Conclusion Adriamycin chemotherapy com- bined with 60 min sessions of hyperthermia showed significant suppression effect on K562/AO2 cell proliferation.The treatment can increase apoptosis rates and down-regulate bcl-2 expression.

OBJECTIVETo explore and compare the clinical effects of three immuno-potentiators and their influence on immune function in preventing and treating recurrent respiratory tract infection (RRI).

METHODSSeventy-two children with RRT were assigned to three groups, the 23 patients in the M group treated with milkvetch extract oral liquid, the 23 in the P group treated by P-transfer factor and the 26 in the U group treated by Utilins injection. Clinical effect was compared among three groups after treatment, and changes of T cell subgroups as well as immune antibodies were detected before and after treatment.

RESULTSThe markedly effective rate in the M, P, and U group was 69.6%, 65.2%, and 73.0% respectively, and the total effective rate 87.0%, 82.6%, and 92.3%, showing an insignificant difference among them (all P>0.05). After treatment, the levels of CD3+, CD4+ and CD4+/CD8+ rose obviously in the three groups (all P<0.05); levels of CD8+ in the M group and the P group lowered significantly (P<0.05, P<0.01), but with no significant difference among three groups in the changes of T cell subgroups (all P>0.05). Serum levels of IgG in all the three groups, IgA in the P group and the M group, and IgM in the M group and the U group rose significantly (P<0.05 or P<0.01), with statistical difference presented in comparing of IgA level in the P group with that in the other two groups (P<0.01).

CONCLUSIONThe clinical effects and the outcomes of immunological indexes' changing are similar in RRI patients treated by the three immuno-potentiators. They all can enhance the immunological function of the organism, strengthen the disease-resistant ability of patients, and reduce the incidence of RRI. Among them, the milkvetch extract oral liquid is worthy of spreading due to its lower cost, simple administration, exemption from painful injection, and good compliance.

UNLABELLEDObjective: In order to assess the integrative cardiopulmonary function after percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD), we used symptom limited maximum cardiopulmonary exercise testing (CPET).

METHODSAll 59 patients diagnosed stable CAD by coronary angiography and echocardiography from August to December of 2014 in our hospital, were divided two groups. PCI group, 31 patients received PCI and drugs. Control group, 28 patients received drugs therapy only. All patients performed CPET before and after the treatment.

RESULTSAll patients safely completed CPET without any complications. The control group, all functional parameters were unchanged (P > 0.05). PCI group, the anaerobic threshold, peak oxygen uptake and peak oxygen pulse increased significantly (P < 0.05) from baseline,but not for others (P > 0.05). For individual analysis, PCI group had higher rates of increase (≥ 10% of baseline) in both peak oxygen uptake and peak oxygen pulse than those of control group (P < 0.05).

CONCLUSIONCPET is an objective, quantitative, safe and effective method to evaluate the clinical therapeutic efficiency. PCI can improve the integrative cardiopulmonary function in CAD patients.
