Objective To investigate the proportion of streptococus pneumonia(SP), haemophilus influenzae (Hi),branhamella catarrhalis (BC), chlamydia pneumonia (CP) and mycoplasma pneumonia (MP) in children with acute pneumonia.Methods Fifty-three hospital-treated children with acute pneumofmonia were included in a prospective study. The enzyme immunoassay was used to detect antibodies in paired sera against non-capsulated Hi, Hi type-B capsular polysaccharide and whole cell, antibodies against pneumococcal pneumolysin, C-polysaccharide and pneumococcal pneumolysin, C-polysaccharide, surface protein A in circulating immune complexes and antibodies against BC and MP. Antibodies against CP by immunofluorescence in paired sera as well as blood cultures were detected in these cases.Results The evidence of bacteria infection was demonstrated in 32 cases (60.4 %) among children with acute pneumonia, of which 11 cases had 2 or 3 organisms coinfection. In these causative agents,SP and CP were the most common organisms (11/53 cases respectively,20.8 %), followed by MP (7/42,16.7 %),Hi(7/53,13.2 %).Conclusion SP,Hi,CP and MP are common causative agents of children with acute pneumonia and multi-agents coinfection isn′t ingnored in our empiric antibiotic therapy for the disease.

?AlM: To evaluate the clinical efficacy of posterior continuous curvilinear capsulorhexis ( PCCC ) combined with anterior vitrectomy in preventing posterior capsule opacification of congenital cataract surgery.
?METHODS:Postoperative clinical follow-up data of 82 cases ( 87 eyes ) with congenital cataract treated in Eye Center of our hospital from January 2011 to August 2014 were retrospectively analyzed. The patients were divided into the surgical control group ( 38 cases, 40 eyes, recieved phacoemulsification + PCCC ) and the study group ( 44 cases, 47 eyes, accepted phacoemulsification+ PCCC + anterior vitrectomy). The incidence of central optic axis opaque and postoperative visual acuity distribution were recorded at 1a follow - up. lntraoperative and postoperative complications were observed.
?RESULTS:The rate of central optic axis opaque grade 0 in control group was 37. 5%, compared to 76. 6% in study groups. The opacity distribution ratio of grade 1,2,3 and 4 in study group were lower than that of control group, and the central optic axis opacity distribution ratio in study group was significantly better than that of control group (P<0. 05). The 19 eyes(47. 5%) of visual acuity testing ≤0. 5 in control group , was higher than the 7 eyes(14. 89%) of that in the study group, The 21 eyes (52. 5%) of visual acuity testing >0. 5 in control group was lower than the 40 eyes ( 85. 11%) of that in study group. The visual acuity between two groups has statistical significance difference after 1a follow-up ( P<0. 05 ) , and the visual acuity in study group was significantly better than that in the control group. The postoperative intraocular pressure at 1mo and 1a follow-up was lower than before operation in two groups ( P<0. 05), but there was no significant difference between two groups in intraocular pressure (P<0. 05).
?CONCLUSlON: Combination of phacoemulsification, PCCC and anterior vitrectomy presents reliable clinical effects on postoperative central optic axis opacity distribution ratio and visual acuity, and it should be adopted to prevent the occurrence of posterior capsule opacification.

Objective To investigate the efficacy and clinical effectiveness of the steroid therapy with the all body and local application on hyperthyroid Graves ophthalmopathy.Methods A total of 57 patients (106 eyes)suffering from hyperthyroid Graves ophthalmopathy who hospitalized in the Department of Ophthalmology of the Second Affiliated Hospital of Harbin Medical University from Mar 2008 to Oct 2011 were enrolled in the study.Of the 57 patients,there were 21 males and 36 females,aged 18 to 57(average 37.28 ± 11.63).The clinical course was from 1 month to 5 years(average 29.63 ± 15.36 months).Based on the patient's age,sex and condition,the 57 patients were randomly divided into steroid pulse therapy with all body group(group SPT,29 patients,54 eyes)and peribulbar injection of long-term steraid group(group PI,28 patients,52 eyes).The patients in group SPT were treated with 0.5-l.0 g methylprednisolone by intravenous infusion daily for 3 days,and then stopped for 7 days,the treatment was repeated once.But the total application dose of methylprednisolone was not overruned 5.0-20.0 g.After that,the patients were treated with oral prednisone 40 mg/d.The dose of prednisone was reduced gradually to 5 mg/d.The total course of group SPT was 3 months.The patients in the group PI were treated with triamcinolone acetonide in periorbital injection of 20 mg once every two weeks for 3 months.After one month treated,all patients were visited.The patients' body weights of two groups were measured before the treatment and after one month treated.The ocular signs of the patients including visual acuity,diplopia,intraocular pressure,exophthalmos and horizontal visual palpebral fissure width were observed before and after the treatment.Results In the group SPT,the average body weight [(62.83 ± 7.23)kg]after the treatment was higher than that before the treatment[(57.03 ±7.13)kg],and also higher than that of the group PI[(59.89 ± 10.67)kg,t =25.25,2.08,all P＜ 0.05]after the treatment.In the group SPT,the average intraocular pressures before and after the treatment were (13.46 ± 1.78)and (13.69 ± 1.41)mm Hg(1 nm Hg =0.133 kPa),respectively.In the group PI,the average intraocular pressures before and after the treatment were (13.52 ± 2.19) and (13.77 ± 2.03)mm Hg,respectively.There was no significant differences before and after the treatment in both gr0ups(P＞ 0.05).In the group SPT and PI,the average exophthalmos after the treatment[(18.63 ± 2.22) and (14.85 ± 2.61)mm]were lower than those before the treatment[(20.78 ± 2.24) and (20.60 ± 2.81)mm,t =9.97,29.68,all P＜ 0.05],respectively.After the treatment,the average exophthalmos in the group PI was significantly lower than that of the group SPT(t =7.79,P＜ 0.05).In the groups SPT and PI,the average averagepalpebral fissure width after the treatment[(15.00 ± 1.80) and (11.65 ± 2.45)mm]were lower than those before the treatment[(17.22 ± 1.89) and (17.44 ± 2.37)mm,t =22.74,91.24,all P ＜ 0.05].After treatment of the group PI,the average exophthalmos was significantly lower than that of the group SPT(t =8.01,P ＜ 0.05).Conclusion Compared with the steroid pulse therapy with all body,the peribullbar application of long-term hormone for hyperthyroid Graves ophthalmopathy is more effective,with lcss side effects and worthy of promotion.

ObjectiveTo explore the effects ofYixintaiGranules on expression of C-Myc mRNA and its protein in myocardial tissues of rabbits with chronic heart failure (CHF).Methods CHF rabbit models were established by ear marginal vein injection of adriamycin. Successfully modeled rabbits were divided into the model group, the Losartan Potassium group, the high-, medium-, and low doseYixintaiGranules groups. Besides, a normal control group was set up. Administration groups were given relevant medicine for gavage, equal volume of physiological saline was administered to rabbits of the model group and the normal control group by gastrogavage. The intervention lasted for 4 weeks, once per day. Echocardiographic indexes and mRNA and protein expression levels of C-Myc in myocardial tissue were detected after 4 weeks of medication.Results Compared with the normal group, the LVEF, LVFS, and E/A of the model group decreased significantly (P<0.01), but mRNA and protein expression levels of C-Myc in myocardial tissues increased significantly (P<0.01). Compared with the model group, the LVEF, LVFS, and E/A of YG groups and Losartan Potassium group increased significantly (P<0.01), but mRNA and protein expression levels of C-Myc in myocardial tissues decreased significantly (P<0.05,P<0.01).ConclusionYixintaiGranules can effectively inhibit the expression of mRNA and protein expression of C-Myc, and improve cardiac function.

The present is aimed at identifying the activation of TRAFs in n asopharyngeal carcinoma (NPC) in vitro. The differential expression of TRAF2\,TRAF3 was not detected in RN A and protein level, whereas the expression of TRAF1 in HNE2-LMP1 cell lines wa s much more abundant than that in HNE2 cell lines, suggesting that TRAF1 may be an inducible molecule; More importantly, TRAF1, TRAF2 or TRAF3 were activated in the HNE2-LMP1 cells, whereas TRAF1, TRAF2 or TRAF3 were not activated in HNE2 cells as detected by the immunoprecipitation-Western blotting assay. These data provide an experimental basis for our study beginning from the signal transduca tion pathway for the eluccidation of the mechanism of LMP1 carcinogenesis in NP C.
