Objective To explore the role of IL-1β in inhalation injury repairment through its effects on the expression of prostaglandin E_2 in cultured airway fibroblasts of mouse. Methods The cultured airway fibroblasts in vivo from male Kunming species mouse were randomly divided into control group and treatment group. The superna-rant and cells were collected at different time after treated with IL-1β. The expressions of PGE_2, COX-2 and mPGES1 protein in supernatant and cells were measured by ELISA and Western Blot. Results ①PGE_2 levels in the cultured airway fibroblast supematant at 8 h(148.2±28.3) ng/L,16 h(267.6±45.4)ng/L,24 h(210.5±38.6) ng/L and 48 h(198.7±36.5) ng/L were higher than that in the control group (P < 0.01), and peaked at 16 h;COX-2 ex-pressions at 8 h(0.478±0.029) COX-2/β-actin, 16 h(0.672±0.047) COX-2/β-actin,24 h(0.617±0.036) COX-2/β-antin, and 48 h (0.593±0.034) COX-2/β-actin were higher than that in control group (P < 0.01), and peaked at 16 h;mPGES1 at 8 h(0.300±0.018) mPGES1/β-actin, 16 h(0.549±0.034) mPGES1/β-actin, 24 h (0.497±0.030)mPGES1/β-actin and 48 h(0.443±0.026)mPGES1/β-actin were higher than that in the control group(P < 0.01), and peaked at 16 h. ②PGE_2 in 0.1 μg/L IL-1β group (142.9±2.3) ng/L, 1.0 μg/L IL-1β group (267.6±45.4) ng/L and 10.0 μg/L IL-1β group (587.3±106.9) ng/L were higher than those in the control group (58.5±16.0) ng/L (P < 0.01), and there was significant difference among the three groups (P < 0.01);COX-2 in 0.1 μg/L IL-1β group(0.525±0.031) COX-2/β-actin, 1.0 μg/L IL-1β group(0.672±0.047) COX-2/ β-actin and 10.0 μg/L IL-1β group(1.012±0.064)COX-2/β-actin were higher than that in the control group (0.309±0.019) COX-2/β-actin (P < 0.01), and there was difference among the three groups (P < 0.01);mPG-ES1 in 0.1 μg/L IL-1β group(0.380±0.021) mPGES1/β-actin, 1.0 μg/L IL-1β group (0.549±0.034) mPG-ES1/β-actin, and 10.0 μg/L IL-1β group(0.879±0.045) mPGES1/β-actin were higher than those in the control group(0.199±0.012)(P<0.01),and there was difference among the three groups(P<0.01).Conclusions IL-1β may upregulate PGE_2, COX-2 and mPGES1 expressions in airway fibroblast, indicating that IL-1β influences PGE_2 synthesis through COX-2 and mPGES1 expression and participates in airway inhalation injury course. Airway fibroblasts may be a main source cell of inflammatory mediators in injury repair.

Objective To evaluate the efficacy of Cobalt 60 radiotherapy in patients with stage I and II non small cell lung cancer. Methods From March 1977 to December 1992, 63 patients with stage I and II non small cell lung cancer were treated. According to the 1997 UICC staging system, 7 patients had stage IA disease, 10 stage IB, 5 stage IIA, and 41 stage IIB. Forty nine patients were confirmed by histopathology, and 14 cases by cytopathology. Fifty eight patients had squamous cell carcinoma, 3 adenocarcinoma, and 2 mixed squamous cell and adenocarcinama. All patients were treated by Cobalt 60. Patients would receive 40 Gy plus a boost of 15～30 Gy. The total dose was D T55～70 Gy in 6～12 weeks. All patients were followed for more than five years. Results The overall 5 year survival for all patients was 17.5%. Fifty eight (92%) patients have died and 11 survived. For the 58 succumbed patients, 52 (90%) died of tumor, and 26 (45%) of them from local failure. Four patients (7%) died of other causes. Conclusion Radiotherapy is an effective treatment option for non small cell lung cancer.

Objectives To analysis the expression difference of eIF4E in bone marrow between the acute myeloid leukemia (AML) and the non-tumor patient,before and after induction therapy,and the different subtypes of AML,and to explore the relation between eIF4E and other molecular biology abnormalities in AML.Methods The bone marrow specimens of newly diagnosed AML and non-tumor control patients were collected.The expression level of eIF4E was detected by RT-PCR.Results The positive rate of eIF4E was 65.2 ％ (101/155) in AML.eIF4E turned to negative in 12 patients (17.6 ％) who got complete remission after induction therapy.eIF4E was negatively expressed in bone marrow of the nontumor control patients.The positive rates of eIF4E were 75.0 ％ (15/20) and 80.8 ％ (21/26) in M4 and M5 type AML,respectively,and was 59.6 ％ (65/109) in other subtype AML (P ＞ 0.05).FLT3/ITD gene mutation was found in 26 cases of newly diagnosed AML.The eIF4E expression and FLT3-ITD gene mutation were independent each other (P ＞ 0.05).Conclusions eIF4E is positive in most of the newly diagnosed AML and turns to negative in part of AML achieving complete remission.The expression of eIF4E is no difference among different subtype of AMLs.eIF4E and FLT3-ITD gene mutation are independent each other.

Objective To investigate the safety and feasibility of electrocoagulation of gallbladder artery in laparoscopic cholecystectomy ( LC) . Methods A total of 376 patients with gallbladder benign diseases underwent LC in our hospital from May 2004 to September 2013.The gallbladder artery was treated by electrocoagulation . Results Because of unclear gallbladder triangle due to abdominal adhesion , conversion to laparotomy was performed in 9 patients.In the remaining 367 patients, three-port LC with electrocoagulation of the gallbladder artery was conducted successfully .Laparoscopic appendectomy was conducted simultaneously in 12 patients.An additional fenestration and drainage of the left renal cyst was performed in 1 patient.Postoperatively, a secondary bile duct exploration was conducted in 1 patient because of bile duct obstruction caused by common bile duct stones . Conclusion The electrocoagulation of gallbladder artery is safe and feasible in LC for the treatment of gallbladder benign diseases .

Based on the needs of healthcare system reform, Australia has implemented activity based funding(ABF) payment mode nationwide, and established the Independent Hospital Pricing Authority as the specific implementation agency in 2011. The main responsibilities and functions of the ABF payment mode covers pricing of medical services, classification of healthcare services, collection of clinical data and cost accounting of healthcare services. ABF payment mode presents outstanding advantages in promoting the capacity of healthcare service, maintaining fairness of healthcare service supplies and carrying out cooperation across different institutions. These efforts provide important references for China in its top-level design of payment method, pilot project of classification system, medical service items and price dynamic adjustment, informationization and information standardization construction among public hospitals.

Objective To observe the effects of physical agents therapy on serum hs-CRP, TNF-α andadiponectin in patients with cerebral infarction and the possible underlying mechanisms. Methods Sixty patientswith cerebral infarction were randomly and equally divided into two groups: 30 cases were treated with physical a-gents therapy ( physical therapy group) , and 30 with drugs only ( drug treated group). Thirty normal subjectsserved as the control group. The level of hs-CRP in the serum was determined by latex agglutination reaction, TNF-and adiponectin were determined by using ELISA before and after therapy. Results The levels of serum hs-CRP and TNF-α of patients with cerebral infarction before therapy were much higher than those of the control group,but adiponectin was significantly lower than those of the control group( P < 0.01 ). After therapy, the levels of ser-um hs-CRP and TNF-α were decreased and adiponectin was increased significantly in both treated groups ( P <0.01 ). Comparison with two treated groups showed that the levels of hs-CRP and TNF-α were lower and adiponec-tin was obviously higher in physical agents therapy group than those in the drug treated group ( P < 0.05 ). Con-clusion The patients with cerebral infarction have low level of serum adiponectin. Physical therapy might exertbeneficial effects on patients with cerebral infarction by the decreasing serum hs-CRP and TNF-α, as well as by ele-vating adiponectin.
