Radiotherapy plays an important role in the treatment of lung cancer .Radiation-induced lung injury is a major complication in the process of radiotherapy .It is of great significance for the treatment and prog-nosis of the diseases to predict the early stage of radiation -induced lung injury in the clinical treatment .TGF-β1(transforming growthfactor-β1) can induce some inflammatory cells including lymphocytes ,neutrophils,mon-ocytes ect,contributing to the formation of fibrosis .Plasma TGF-β1 shows different levels followed different sta-ges of radiation-induced lung injury .This article reviews the value of cytokine TGF -β1 in predicting the radia-tion-induced lung injury over various aspects such as singlely used ,combined with radiation physics and other cytokines,and genomics.

The T help cell 1(Th1) and Th2 cell classification have provided the framework for understanding CD4+ T cell biology and the interplay between innate and adaptive immunity for almost two decades. Recent studies have defined a previously unknown subset of the CD4+ T cell effectors, the Th17 lineage. The uncover on the differentiation of IL-17-producing effector T cells from naive T cell precursors provides insights into mechanisms by which signals from cells of the innate immune system guide alternative pathways of Th1, Th2 or Th17 development. Th17 lineage has an important role in autoimmune and inflammatory diseases. This promises to change our understanding on the immune regulation, immune pathogenesis and host defense. The identification, differentiation and immune function of the new subsets of Th cells, Th17 cells will be reviewed.

Objective To assess the risk factors of pulmonary infection in patients with cerebral hemorrhage,and then to provide references for policy-making.Methods Relative literature of crosssectional or case-control studies about risk factors of pulmonary infection in patients with cerebral hemorrhage was searched by computer in data bases such as CNKI,VIP,CBM,WanFang Data and PubMed from January of 1994 to October 2014.Resluts A total of 22 studies (2 case-control studies and 20 crosssectional studies) were brought into the study.The risk factors' OR and its 95％CI was 2.64(2.10-3.33) for over 60 years of age,2.05(1.56-2.69) for smoking history,3.07(2.24-4.19)for those who have diabetes,3.36 (2.40-4.70) for those who have chronic pulmonary diseases,1.54 (1.16-2.05) for those who have heart diseases,2.38 (1.83-3.08) for those who have a history of stroke,5.07 (3.15-8.16) for disorder of consciousness,2.78(2.36-3.27) for amount of bleeding over 30ml,2.85(2.22-3.66) for deviated from midline,2.58 (1.60-4.17) for breaking into ventricle,2.05(1.67-2.51) for high level of fasting blood sugar respectively,and so on.Conclusions Prophylactic measures can be carried out according to the risk factors of pulmonary infection in patients with cerebral hemorrhage,and then to reduce the incidence rate of pulmonary infection.

Objective To sum up the clinical experience of operative management of tibia plateau fracture in senile patients. Methods 35 cases of senile tibia plateau fracture were treated with different ways of internal fixation, including screw, cannulated compression screw, L shaped plate, and T shaped plate. Results All the 35 cases were followed up and the time ranged from 6 months to 2 years. X ray films showed that the anatomical reduction was reached and the fractures healed in 33 cases. The final results were rated according to Merchant criteria: excellent in 22 cases, good in 9 cases, fair in 2 cases and poor in 2 cases. The excellent and good rates were 85.7%. Conclusions Operation on senile patients with tibia plateau fracture should be performed early so as to reconstruct the articular surface. Rigid fixation and bone transplantation are impartment means to avoid plateau collapse, and early functional exercise can reduce postoperative complications.

Objective To study the effects and mechanism of focal mild hypothennia on brain inflarnmation response during the early stage of tranrntic brain injury(TBI)in rats.Method Traumatic brain injury wag produced in anesthetized rats by using free-falling impact model.Sixty-three male Sprague Dawley rats were randomly divided into three groups:TBI group,focal hypothermia group,and sham group.each group with 7 SD rats.Then all groups Wag further subdivided into three subgroups according to different intervals after TBI.Myeloperoxiduse (MPO)activity assay,immunohistochemical staining for the detennination of intercellular adhesion molecule-1(ICAM-1)expression and the number of ICAM-1 positive blood vessels were counted up in the traumatic brain tissues.All data were analyzed by SNK-q test Using SPSS 10.0 sofeware program.Results The number of ICAM1 positive blood vessels was significantly fewer in the rats of focal hypothermia group than those in the rats of TBI group at different intervals after TBI(P<0.01).Similarly,the MPO activity was significantly lower in the rats of focal hypothermia group than that in the rats of TBI group(P<0.01).Conclusions Focal mild hypothermia could significantly decrease neutrophil infdtration and ICAM-1 expression in the traumatized areas.It might be one of the mechanisms of focal mild hypothermis for TBI.

Objective To study the effect of periodontitis on rats with chronic bacterial prostatitis. Methods A total of 80 male rats were randomly divided into the 4 weeks group (n=40) and the 8 weeks group (n=40), and then the two groups were randomly divided into the normal control group (N=10), the periodontitis group (PE=10), the chronic bacterial prostatitis group (CBP=10), and the peri-odontitis+chronic bacterial prostatitis group (CBP+PE=10) respectively. The pathological changes, inflammation score, level of TNF-αand IL-1β, and indicators of periodontal of all rats were observed. Results In the 4 weeks group, the indicators of periodontal in PE group and CBP+PE group were higher than that in N group and CBP group (P<0. 05), but there was no significant difference between PE group and CBP+PE group as well as between the N group and the CBP group (P>0. 05). The pathological changes, inflammation score,TNF-αlevel ,IL-1 β level in CBP+PE group and CBP group were higher than that in N group and PE group (P<0. 05), while there was no sing-nificant difference between N group and PE group as well as between CBP+PE group and CBP group (P>0. 05). In the 8 weeks group, the indicators of periodontal in PE group and CBP+PE group were higher than that in N group and CBP group (P<0. 05), but there was no sig-nificant difference between PE group and CBP+PE group as well as between the N group and the CBP group (P>0. 05). The pathological changes, inflammation score, TNF-α level , IL-1 β level in CBP +PE group and CBP group were higher than that in N group and PE group (P<0. 05),while there was no singnificant difference between N group and PE group (P>0. 05). The pathological changes, inflam-mation score,TNF-α level ,IL-1 β level in CBP+PE group were higher than those in the CBP group (P<0. 05). Compared between 4 weeks group and 8 weeks group, there was no obvious difference in N group in terms of periodontal indexes. Periodontal indexes in 8 weeks PE group was higher than that in 4 weeks PE group (P<0. 05), but there was no significant difference prostate tissue pathology, inflamma-tion score,TNF-α level,IL-1βlevel (P>0. 05). Pathology, inflammation score,TNF-αlevel, IL-1βlevel in 8 weeks CBP group were low-er compared to 4 weeks CBP group (P<0. 05), and there was no significant difference between the indexes of periodontal (P>0. 05). Prostate tissue pathology, inflammation score, TNF-αlevel, IL-1βlevel in 8 weeks CBP+PE group were lower than that in 4 weeks CBP+PE group (P<0. 05), but indicators of periodontal in 8 weeks CBP+PE group were higher than 4 weeks CBP+PE group (P<0. 05). Conclusion Chronic bacterial prostatitis combined with periodontitis can inhibit self-healing tendency of chronic bacterial prostatitis of rats and keep rats in chronic inflammatory phase.

Objective To investigate the safety and feasibility of uterine arterial embolization (UAE) combined with hystersocpic excisionl of exogenous cesarean scar pregnancy (CSP). Methods Totally 67 patients with exogenous CSP treated with selective UAE combined with hysterscopic surgery in Shengjing Hospital of China Medical University were analyzed retrospectively; 35 patients in Group A (thickness of the cesarean scar>3 mm), while 32 patients in Group B (thickness of the cesarean scar≤3 mm). The following clinical parameters including operative time, intraoperative blood loss, quantity of postoperative uterine drainage, postoperative hospital days, the time for the mass absorption and the return ofβ-hCG to normal were compared. Results All hysterscopic procedures were successfully completed in Group A, and only one case underwent a second hysteroscopic excision due to the 1-month postoperative ultrasound examination indicating a mass located in the cesarean scar and a slow decline of β-hCG. Three cases of Group B were transformed to laparoscopic or laparotomy operation and 7 cases underwent a second surgery. The volume of introperative blood loss was (97±41) ml in Group A and (161±92) ml in Group B, the difference was statistically significant (P<0.01). But the operative time, quantity of postoperative uterine drainage, postoperative hospital days, the time for the retrun ofβ-hCG to normal and the mass absorption in Group A were (36±9) minutes, (38±13) ml, (3.5±0.5) days, (26±5) days, (82±17) days, in Group B were (37± 9) minutes, (42 ± 16) ml, (4.0 ± 0.7) days, (28 ± 8) days, (88 ± 15) days, respectively, the differences were not statistically significant (all P>0.05). Conclusions For exogenous CSP, when the thickness of cesarean scar is ≤3 mm, whether or not undertaking UAE, it should be seen as contraindication of hysterscopic surgery. UAE combined with hysterscopic surgery for the treatment of exogeous CSP with the cesarean scar thickness>3 mm is safe and feasible according to patients condition and should be performed by experienced hysteroscopist.
