Objective To study the effects of Qingjinkangkuoyin (QJKKY) on TNF-α and NE in rats with bronchiectasis.Methods Models were established by intrabronchially injecting with pseudomonas aeruginosa,and divided into 5 groups by random:the QJKKY high dose treatment group (given high dose of QJKKY into stomach),the QJKKY low dose treatment group (given low dose of QJKKY),the levofloxacin group (given levofloxacin),the model group (given normal saline),and the normal contrast group (given normal saline).After 2 weeks of treatment,the histopathology of lung tissue,the levels of TNF-α and inflammatory cells in peripheral blood and NE in rats' lung tissue were detected.Results Compared with the model group (160.425±9.9293)ng/L,QJKKY could decrease the level of TNF-α in blood significantly [high dose of QJKKY treatment group was (137.133±6.1646)ng/L,P＜0.05]; the expression of inflammatory cells in serum were decreased significantly by QJKKY [high dose of QJKKY treatment group was (1.106± 0.3580) 109/L,P＜0.05].Low dose of QJKKY treatment group was (1.086 ±0.2433) 109/L,(P＜0.05) ; the expression of NE in lung tissue were decreased remarkably by QJKKY [high dose of QJKKY treatment group(80.697 ±4.5877)ng/L,P＜0.05]; low dose of QJKKY treatment group is (80.747±3.6925)ng/L,(P＜0.05); and the histopathologic change of lung tissue in QJKKY treatment groups were ameliorated under light microscope by HE staining.Conclusion Qingjinkangkuoyin could cure bronchiectasis by decreasing the expression of TNF-αin peripheral blood and NE in rats' lung tissue.

OBJECTIVE:To compare anesthesia effects of 3 anesthesia methods,to investigate anesthesia improvement method for bronch fiber oscope. METHODS:315 patients undergoing bronch fiber oscope were randomly divided into group A(106 cas-es),group B(104 cases)and group C(105 cases). Group A was treated with traditional bronch fiber oscope lidocaine atomization local anesthesia,group B was treated with modified bronch fiber oscope pethidine combined with lidocaine atomization local anes-thesia and group C was treated with three-limb tube connected with laryngeal mask and target-controlled propofol and remifentanil general anesthesia. SaO2,SBP,DBP,heart rate,breathing rate,excellent anesthesia rate,compliance rate,the rate of bodymove-ment and choking,pain recalling rate were compared among 3 groups before and during examination,and ADR was observed. RE-SULTS:Compared with before examination,SaO2 of group A was decreased significantly during examination,with statistical sig-nificance(P<0.05);that of group B and C had no obvious change before and during examination. Blood pressure,heart rate and breathing rate of 3 groups had no obvious change before and during examination. The excellent anesthesia rate and compliance rate of group A were significantly lower than those of group B and C,but the rate of bodymovement cough and pain recalling rate were significantly higher than group B and C,with statistical significantly(P<0.05). The excellent anesthesia rate and compliance rate of group B were significantly lower than those of group C,but the rate of bodymovement cough and pain recalling rate were signifi-cantly higher than group C,with statistical significance (P<0.05). No ADR was found in 3 groups. CONCLUSIONS:Modified bronchoscope atomization local anesthesia and modified painless bronchoscope are better than traditional bronch fiber oscope atomi-zation local anesthesia in anesthesia effect,safety,degree of comfort and acceptability. Modified bronchoscope atomization local an-esthesia was best but most expensive,so these methods can be chosen according to patient’s condition.

Objective To investigate the effect of tacrolimus on Langerhans cell migration in order to understand the therapeutic mechanism of tacrolimus. Methods C57BL/6 mouse injected with different doses of tacrolimus was stimulated by FITC at ear back. After twelve hours, the number of Langerhans cells which took antigen and migrated to lymph nodes was measured by flow cytometry. The number of Langerhans cells which took antigen and resided in epidermis was examined by immunohistochemical staining. Results After injection with tacrolimus, the number of Langerhans cells which took antigen and migrated to lymph nodes was reduced, especially at 12 hours before stimulation by FITC. The reduction was significantly different between the high dose and low dose injection groups. However,the number of Langerhans cells residing in epidermis was significantly higher in tacrolimus injection group than that in the control. Conclusions Tacrolimus, a new kind of immunosuppressive drug,may probably suppress Langerhans cell migration and therefore inhibit immune response in some diseases.

OBJECTIVETo observe improved effects of Jingjin acupuncture on fine activity of hemiplegic hand in recovery period of stroke.

METHODSFifty cases were randomly divided into an observation group and a control group, 25 cases in each one. Regular western medicine treatment, rehabilitation training and regular acupuncture (in which Shuigou (GV 26), Baihui (GV 20), Neiguan (PC 6), etc. were selected) were applied in both groups. Additionally, muscles in palm side of affected hand, dorsal metacarpophalangeal joints and proximal interphalangeal joints were treated with acupuncture in the observation group, once every other day and electroacupuncture was applied when arrival of qi was acquired. Baxie (EX-UE 9) in the affected hand were needled in the control group, and electroacupuncture was added when arrival of qi was acquired. Ten days of treatment was considered a treatment course, and after two courses Lindmark score, Brunnstrom movement function grade, joint range of hand and Barthel index (BI) were observed in two groups.

RESULTSCompared before the treatment, the Lindmark score in two groups were both improved after the treatment (both P < 0.01). Compared with the control group, the motor coordination ability, sensory function and total score of Lindmark in observation group were obviously improved (differences before and after treatment: 8.24 +/- 3.07 vs 6.84 +/- 2.43, 3.52 +/- 2.33 vs 2.16 +/- 2.12, 11.76 +/- 3.55 vs 9.00 +/- 3.62, all P < 0.05). The Brunnstrom movement function grade was significantly improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group (P < 0.05). The joint range of hemiplegic hand was improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group [differences before and after treatment: (25.35 +/- 10.91) degrees vs (18.65 +/- 7.86) degrees, p < 0.05]. The score of BI was also significantly improved after treatment in two groups (both P < 0.01).

CONCLUSIONThe Jingjin acupuncture could effectively improve fine activity of hemiplegic hand in recovery period of stroke prove daily life ability.

Objective To investigate the mechanisms of tacrolimus on the migration of Langerhans′ cells. Methods The concentration of MCP-1 in the cultured supernatants of HaCaT cell treated with tacrolimus was determined by ELISA. The expression level of MCP-1 mRNA in HaCaT cell treated with tacrolimus was studied by RT-PCR method. Results The concentration of MCP-1 in HaCaT cell treated with 625 ～ 5 000 ng/mL of tacrolimus was significantly decreased. The expression level of MCP-1 mRNA was also markedly decreased. Conclusions Tacrolimus may probably decrease the expression of MCP-1 in keratinocytes and suppress the chemotactic ability of Langerhans′ cells precursor and Langerhans′ cells, thus inhibiting or diminishing certain local immunoreaction.

Objective To investigate the expression of IL-8 and CXCR2 on keratinocytes from psoriatic lesions and their roles on clinical and pathologic manifestations. Methods The chemotaxis of psoriatic lesional keratinocytes was detected by micropore loculus test. The concentration of IL-8 was determined in the cultured supernatants of psoriatic keratinocytes by ELISA. The expression of CXCR2 on keratinocytes from affected skin was tested by flow cytometry. Results The chemotaxis for neutrophils by the cultured supernatants of psoriatic lesional keratinocytes was significantly stronger than that by controls. The concentration of IL-8 in the cultured supernatants of psoriatic lesional keratinocytes was also increased. The expression of CXCR2 on psoriatic keratinocytes was significantly increased. Conclusions The psoriatic epidermal hyperproliferation may be correlated with up regulation of IL-8 production and CXCR2 expression on psoriatic keratinocytes. At the same time, the psoriatic inflammation may be partly related to the increase of secretion of IL-8, which has chemotactic capacity, by keratinocytes. IL-8 and CXCR2 may be involved in the pathogenesis of psoriasis.

ObjectiveTo identify serum specific protein biomarkers for the early diagnosis of lymphoma patients by using surface enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS)protein chip array.MethodsSELDI-TOF-MS technique and weak cation exchanger (WCX2)protein chip were used to detect the serum proteomic patterns of 96 patients with lymphoma (86 patients with non-Hodgkin lymphoma and 10 patients with Hodgkin lymphoma)and 30 normal control.The serum level of LDH were measured by biochemical methods,the serum level of β2-MG and CA125 were detected by enzyme-linked immunosorbent assay (ELISA).ResultsFour protein peaks pattern mass/charge ratio (M/Z) 6880,8564,8692 and 13751 were decreased in lymphoma patients,and they could be used to distinguish lymphoma from healthy people and other malignant tumors.Their sensitivity and specificity were 82.29 ％ and 80.00 ％,78.13 ％ and 73.30 ％,75.00 ％ and 80.00 ％,71.88 ％ and 83.30 ％ respectively in lymphoma patients.When it was used to early diagnosing lymphoma in stage Ⅰ or Ⅱ,the sensitivity of four protein peaks pattern (M/Z 6880,8564,8692 and 13 751) were 77.55 ％,71.43 ％,71.43 ％ and 67.35 ％respectively and the specificity of all four protein peaks pattern were 100.00 ％.Four protein peaks pattern sensitivity were higher than LDH,CA125 and β2-MG respectively.ConclusionApplication of SELDI-TOF-MS can be of great potential for the early diagnosis of lymphoma patients.

Objective To study the diagnostic value of combined detection of serum CEA,CA199,CA125,AFP and fecal occult blood(FOB) in Dukes B stage colon carcinoma.Methods The above indicators in 56 patients with colon carcinoma (colon carcinoma group),35 patients with colonic polyp benign disease and 41 healthy individuals undergoing physical examination were measured.Then the sensitivity,and specificity of single index detection and their combined detection were analyzed.Results The levels and positive rates of CEA,CA199,CA125 and FOB in the colon cancer group were significantly higher than those in the colonic polyp group and healthy control group (P＜0.05),but the AFP level and positive rate had no statistical difference compared with the colonic polyp group.Serum CEA,CA125,CA199 and FOB were selected into the Logistic regression equation.The corresponding areas under the curve (AUC) were 0.745,0.886,0.792 and 0.864 respectively;the positive detection rates were 48.2 ％,35.7 ％,39.3 ％ and 78.6 ％ respectively.The combined detection could increased the specificity,sensitivity and AUC to 87.5 ％,92.1％ and 0.957,which were more superior to that in the single index detection.Conclusion The combined detection of serum CEA,CA199,CA 125 and FOB can provide the powerful basis for early diagnosing colonic cancer.
