Objective To investigate the relationship between renin (REN) gene G10631A, angiotensinogen (AGT) gene T704C mononucleotide polymorphisms and cerebral infarction and to investigate the mechanisms and characteristics of cerebral infarction from molecular level. Methods REN gene G1063A and AGT gene T704C polymorphisms in 82 patients with cerebral infarction and 89 controls were detected with polymerase chain reactionrestriction fragment length polymorphism. The differences of the genotypes and allele frequencies were compared between the patient group and the control group. Results The frequency of REN 10631AA genotype (31. 7% vs. 10. 1%,χ2 =12. 816, P = 0. 002) and the frequency of A genotype (49. 4% vs. 30. 3% χ2 = 12. 969, P =0. 000), as well as the frequency of AGT 704 CC genotype (63. 4% vs. 34. 8% χ2 = 15. 029, P = 0. 001) and the frequency of A genotype (79. 9% vs. 61. 2% χ2 = 14. 173, P = 0. 000) in the cerebral infarction group were all significantly higher than those in the control group; the frequency of haplotype 704C 10631A was also significantly higher than that in the control group (P=0. 000). Conclusions REN 10631AA genetype and A allele as well as AGT 704 CC genetype and C allele may be the susceptible factors of cerebral infarction. Haplotype 704C-10631 A may be a genetic risk factor for the occurrence of cerebral infarction.

Objective To explore the diagnosis and of immune neutopenia.Methods Clinical data of 150 patients with immune neutropenia were collected and analyzed.Results Of 150 patients with immune neutropenia,35 cases went male(23.3％),115 cases were female(76.7％),and male to female ratio was 1 ∶ 3.3.Based on the difference produced way of granulocytes associated antibody,all patients could be divided into alloimmune neonatal neutropenia 9 cases (6.0％),drug-induced immune neutropenia 28 cases (18.7 ％),primary autoimmune neutropenia 22 cases(14.6％),and secondary autoimmune neutropenia 91 cases (60.7％).Secondary autoimmune neutropenia included 39 cases of systemic lupus erythematous,21 cases of rheumatoid arthritis,2 cases of immune hemolytic anemia accompany with neutropenia,6 cases of immune thrombocytopenia accompany with neutropenia,3 cases of autoimmune hepatitis,16 cases of autoimmune thyroiditis,and 4 cases of Sjogren's syndrome.Conclusion The majority of primary immune neutropenia are female,which is usually secondary to autoimmune diseases.The diagnosis of primary immune neutropenia is very complicated,which requires a long period of clinical observation and follow-up.The majority of granulocytes associated antibody is IgG in the autoimmune neutropenia patients.Yet sometimes two or three kinds of antibodies were increased as well.

Objective To systematically review the literature evaluating efficacy and adverse events of propranolol for infantile hemangiomas (IHs).Methods We searched the Cochrane,Medline,Wiley,CNKI and Wanfang Databases for all studies on the response of IHs to propranolol only which were published between June 2008 and May 2013.Results A total of 23 studies were collected,including 14 case reports and 2 follow-up studies which were without random and control;another 6 studies were clinical controlled trials and 1 study was RCT.Total 716 patients were included,and never received other treatments before propranolol.Propranolol was initiated at a mean age of (4.5 ± 0.5)months at a mean dose of 2.1 mg/kg/day and for a mean treatment duration of (9.7±9.2) months.The effective rate for patients with IHs treated with propranolol was 97％ (691/716),and patients after treatment completion reported IHs recurred in 8.6 ％ of patients.The adverse effects rate was 31％(223/7167) which most common adverse events were changes in sleep (n=35),gastrointestinal reaction (n =52) and decreased heart rate (n =73),and 5 patients discontinued the treatment because of the serious adverse events.Conclusions This systematic review of 716 patients treated with propranolol for IHs show a high rate of efficacy and a low rate of serious adverse events,and it is a better treatment of infantile hemangioma,but we should pay more attention to the serious adverse events and strictly select indications.

Objective To explore the changes and significance of Klotho protein levels in different stages of chronic kidney disease (CKD). Methods From March 2015 to December 2017,176 patients with CKD admitted to nephrology department of Inner Mongolia People＇s Hospital were selected as the study object (CKD group), and 80 healthy patients in our hospital were selected as the control group in the same period. The serum Klotho levels of CKD patients and control group at different stages were detected by double antibody sandwich ELISA, and the differences between each group were compared. Results The serum Klotho level of CKD group (( 4. 84 ± 1. 87) μg／L) was significantly lower than that of the control group ((9. 11± 3. 14) μg／L) ( t＝ 13. 82, P＜0. 01) . One-way anova showed that estimated renal glomerular filtration rate (eGFR),serum albumin (ALB),hemoglobin ( Hb),blood calcium ( Ca) and serum Klotho were gradually decreased,while phosphorus (P) and creatinine (Cr) in serum were gradually increased,and the difference was statistically significant among the five stages( all P＜0. 01). Spearman correlation analysis showed that Klotho level was positively correlated with eGFR and Ca,and negatively correlated with CKD stage,Cr and P (r＝0. 369,0. 160,－0. 200,－0. 250,－0. 230,all P＜0. 05). The multiple linear regression equation showed that Klotho level was positively and independently correlated with eGFR ( t＝ 3. 89, P＜0. 001),and negatively correlated with CKD staging independently (t＝－4. 12,P＜0. 001). Conclusion The expression level of serum Klotho protein in patients with CKD is lower than that of healthy people,and it decreases with the increase of CKD stages,which is closely related to the deterioration of renal function. It can be used as a reference index to evaluate the incidence and severity of CKD.
