Children with plastic bronchitis,characterized by unknown origin,insidious onset,rapid progress,severe symptom and high mortality,is a relatively rare disease.Also,it is difficult to diagnose and treat with plastic bronchitis characterized by marked airway obstruction,via the formation of large gelatinous or rigid airway cast.It is associated with certain diseases including bronchial asthma,cystic fibrosis,accompanied with acute chest syndrome with sickle cell disease,congenital heart disease and bacterial and viral respiratory infection.Clinicians should be aware of this disease,and early bronchoscopy should be intervened.

Fatigue is one of the most common complaints in cancer patients that profoundly affects all aspects of quality of life.However,cancer-related fatigue remains under recognized and poorly treated.This rcview has been conducted with the causes and potential treatments of fatigue in cancer patients.The methods for evaluating fatigue,and possible therapeutic options are also discussed.

Retinal ischemia-reperfusion injury (RIRI) is a common pathological and physiological clinical oculopathy,which can occur in retinal artery and vein occlusion,diabetic retinopathy and acute angle-closure glaucoma.The resulting ischemia can cause cell metabolic dysfunction,serious retinal damage and descending visual function.RIRI is the result of multiple factors.The currently accepted hypotheses mainly include the injury effect of oxygen-derived free radicals,intracellular calcium overload,the action of leucocyte and apoptosis.However the protection and treatment research in the RIRI is limited.The present paper reviews the progression in the drug intervention of RIRI.

The incidence of gastric cancer is in the fourth place of all cancers in worldwide ,and the fatal-ity rate is in the second place .Standard chemotherapy regimens play an important role in prolonging gastric cancer survival rate.However,most of gastric cancers are in advanced stage when diagnose is finally made .The current medical practice can only meet the limited treatment options .In the last several decades ,study of the molecular mechanisms of gastric cancer gets constant new progress .By inhibiting the human epidermal growth factor receptor 2(Her-2)for advanced gastric cancer,it provides a new treatment for patients.Trastuzumab is a kind of Her -2 monoclonal antibody .It is the first kind of targeted therapy drug for the treatment of metastatic gastric cancer .A combination of trastuzumab with cisplatin and 5-fluorouracil based chemotherapy benefits gastric cancer overall survival.Overexpression of Her -2 provides evidence for the targeted therapy .So we reviewed Her -2 excessive expression of gastric carcinoma in recent years and represented by bead sheet resistance to targeted therapy .In this paper ,research of overpression of Her -2 and targeted threrapy in gastric cancer are summarized .

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disorder of hematopoietic stem cells due to acquisition of somatic mutations.Somatic mutations in phosphatidylinositol glycan class A (PIGA) account for intravascular hemolysis and other PNH manifestations,but the pathophysiology of clonal expansion of PNH cells cannot be elucidated clearly.PNH is closely related to aplastic anemia and myelodysplastic syndromes.Today,the gold standard for PNH is flow cytometry to detect the absence or severe deficiency of glycosylphosphatidylinositol (GPI)-anchored proteins on white and red blood cells.However,PNH diagnosed by phenotype is a group of heterogeneous disease in pathogenesis.Eculizumab,a first-in-class monoclonal antibody that inhibits terminal complement,is highly effective in stopping intravascular hemolysis and improving quality of life.Further research on the pathogenesis of PNH would be helpful to understand the underlying reasons for PNH phenotype cells in different patients,improve differential diagnosis and more targeted and specific therapy.Research progress in recent years will be reviewed in this article.

Objective To explore effects of spinal-epidural anesthesia combined with epidural anesthesia for cesarean section anesthesia and hemodynamic maternal.Methods 122 cases of mothers for cesarean section surgery in Lyuliang Municipal People's Hospital from January 2012 to January 2014 were selected,and they were divided into two groups by randomized single-blind method.The control group (61 cases) was given simple subdural anesthesia (EA),while the observation group was given CSEA.The maternal hemodynamics,efficacy of the anesthesia and adverse reactions were compared between the two groups.Results The onset time of anesthesia,maximum block level,amount of anesthetic in the observation group were (3.87 ± 0.25) min,(5.04 ± 0.41) T,(6.87 ± 0.92) mL,which were significantly reduced compared with the control group (t =8.55,8.03,6.45,all P ＜ 0.05),and the duration of anesthesia was (116.76 ± 7.89) min,which was significantly increased compared with the control group (t =7.93,P＜0.05).The MAP and HR of observation group in T1,T2,T3 showed no significant differences compared with T0 (P ＞ 0.05);while the control group of patients with the MAP at T2 had obvious reduction compared with T0 (t =8.34,P ＜ 0.05),T2,T3 compared with T0 decreased significantly (t =7.87,7.56,all P ＜ 0.05).The incidence rate of adverse reaction in the observation group was 9.84％,which was significantly lower than 24.59％ of the control group,the difference was statistically significant (x2 =9.45,P ＜ 0.05).Conclusion The lumbar epidural anesthesia for cesarean section anesthesia had significantly fewer adverse reactions,and it can remain stable maternal vital signs,which was an ideal cesarean for section anesthesia.

Integrative Chinese and western medicine therapy exhibited their achievements in reducing adverse reactions, improving the quality of life and prolonging the survival of the primary liver cancer (PLC) patients, which are reflected in the results of surgery, interventional therapy, chemotherapy, radiotherapy, recurrence and metastasis, promoting the liver cell apoptosis, and enhancing the effect of western medicine therapy. This article mainly overviews the current situation of clinical and experimental researches.

Objective To assess the association of interleukin-6 (IL-6)-174C/G and-572C/G gene polymorphisms with hy-pertension risk.Methods The electronic databases,such as Pubmed,Web of Science,Google scholar,China National Knowl-edge Infrastrure and Wanfang database were searched by the interleukin-6,polymorphism,IL-6,hypertension,high blood pressure as the keywords/abstract.Random effect model was used to calculate the pooled odds ratio.Results The meta-a-nalysis included 6 studies with 1 041 hypertension cases and 1 088 health subjects,which was no significant association be-tween IL-6-174C/G gene polymorphism and hypertension (C vs G:OR=0.50,95%CI=0.22~ 1.14,P =0.10),and in the stratified analysis by ethnicity,no significant was found in Asian subgroup (C vs G:OR=0.75,95%CI=0.41~1.38,P =0.36).There was also no association between IL-6-572C/G gene polymorphism and hypertension in Asian (C vs G:OR =0.76,95%CI=0.51~1.15,P =0.20).Conclusion The IL-6-174C/G and-572C/G gene polymorphisms were suggested to be no related to the increased risk of hypertension in Asian.

AIM: To investigate the kinetics of interleukin-6(IL-6) protein and mRNA expressions in the co-culture of rat brain vascular endothelial cells(VECs) with fibrin.METHODS: The IL-6 concentration were measured by rat IL-6 ELISA kit and the IL-6 mRNA was measured by real-time PCR after development an in vitro model of in situ fibrin polymerization on rat brain vascular endothelial cells.RESULTS: Fibrin induced IL-6 expression.The IL-6 antigen concentration increased significantly in 1.0 g/L media group compared to the low dose fibrin group or control media group(P

The case of LI Li-yun involves the right of life,the right of informed consent and the special right to intervene from the inspection of right.By analyzing the concepts of three kinds of rights and discussing the conflicts between the right of informed consent,the right of life,and the special right to intervene,it presents the principles of equity of right and the measures of legal insurance which are essential conditions to end this kind of tragedy.
