Objective To study the differences in clinical characteristics and etiology in bronchopneumonia and lobar pneumonia,and provide the basis for the clinical diagnosis and treatment.Methods A retrospective study was performed on 100 children with lobar pneumonia and 200 children with bronchopneumonia from Dec.2005 to Dec.2007.Antibodies of mycoplasma(MP) and chlamydia(CP) were detected with quantitative enzyme linked immunosorbent assay of serum samples which were collected on addmission.On the second day morning,axenic sputum samples of laryngeapharyngis at pars were collected with onetime asepsis aspiration sputum tube by negative pressure for bacterial culture,and the common seven viruses were detected with direct immunofluorescence,and MP DNA,CP DNA were detected.The results and the clinical data and the characters of sternum were analyzed.Results Lobar pneumonia was more in the elder children,and the features were fever and cough in clinic,absence in physical sign of bellow,and inflammation of one pulmonary lobe in X-ray.Sixty-one percent of childhood lobar pneumonia had MP infection in laboratory examination.But bronchopneumonia was found more in infants and young children,whose features were cough,dyspnea and catarrhus in clinics,wheezy phlegm and stridor in physical sign of bellow,pulmonic shadow of spot and lamellar in X-ray.Bacteria were the most common pathogen in bronchopneumonia.Conclusions Lobar pneumonia was different from bronchopneumonia in age and clinic features and sternum characters of patients,and much more different in etiology.Bacterial infection was important in bronchopneumonia.But in lobar pneumonia,MP infection occupied 61.0%,which was different from traditionaletiology.Moreover,the MP infection rate in infant and young children tend to increase obviously.

Objective To investigate the efficacy and safety of bortezomib-based induction regimen followed by autologous hematopoietic stem cell transplantation (ASCT) in pationts with multiple myeloma (MM). Methods A retrospective analysis was performed upon clinical data of 62 MM patients who received bortezomib-based induction regimen followed by ASCT from June 2006 to June 2011.All patients were followed up to September 30,2011.Results Overall response rate [ complete remission (CR) + near complete remission (nCR) + partial remission (PR) ],≥ nCR rate (CR/nCR) and CR rate of postinduction with bortezomib-based regimen were 88.7％,66.1％ and 24.2％,respectively.After ASCT,CR rate and CR/nCR rate were increased to 50.0％ and 82.3％,respectively,with significant differences (P =0.003 and P =0.032).The median time of neutrophil and platelet engraftment was 12.0 (9-43) days and 13.5 (0-120) days,respectively. Significances were found in neutrophil and platelet engraftment between MM patients with and without prior exposure to alkylating agents. Furthermore,engraftment of neutrophil and platelet in patients receiving peripheral blood stem cell transplantation were faster than those receiving bone marrow transplantation.No unexpected side effects occurred.The median time of follow-up was 26.5 (7-61) months.The median overall survival (OS) was not reached and the median progression-free survival (PFS) was 30 months.There were significant differences in OS and PFS between patients obtaining CR/nCR and those with ≤ PR before ASCT.Conclusions Bortezomib-based induction regimen can improve the efficacy of ASCT in MM patients.The side effects are tolerant.Higher response quality before ASCT can translate to high rates of OS and PFS following high-dose therapy and stem cell transplantation.

Abstract?AlM:To analyze of the clinical features of acute retinal pigment epitheltis ( ARPE) .?METHODS: The clinical data of 36 ARPE patients ( 40 eyes) attending this center from January 2008 to January 2014 were reviewed retrospectively. Of them, 21 patients (58.3%) were male (male :female=1:0. 71). The mean age was 40. 92±7. 13 years old (range:17~60y). The mean best-corrected visual acuity (BCVA) was 0. 50±0. 26 with a range of 0. 3 ~ 1. 0. Thirty-two patients were unilateral cases. All the patients were examined for BCVA, funds photography, fluorescein fundus angiography ( FFA ) , optical coherence tomography ( OCT) . FFA was shown as three types: type ▏ to multiple black light or grape variety fluorescent spot; Type II for l lesions visible fluorescence leakage; Type Ⅲ lesions with choroid neovascularization ( CNV ) . OCT was the following three forms: multiple RPE lesions layer reflection intermittent, proliferation ( type ▏); pigment epithelial detachment with limitations neural epithelium ( typeII);types l and ll with CNV ( type Ⅲ) .?RESULTS: Ocular fundus showed that the lesions were multiple dark-gray spots with a dark circumscribed area at the macular or nearby in all 40 eyes. FFA showed:21 eyes were type ▏, 17 eyes were type II and 2 eyes were typeⅢ, BCVA between type ▏ and type II was statistically significant (P<0. 05), the same was between type 芋. BCVA between different cases in the same type and between type II, Ⅲ, was no statistical difference ( P>0. 05). OCT showed 21 eyes wwere type ▏, 17 eyes were type II and type Ⅲ 2 eyes. BCVA average between type▏ andIIwas statistically significant (P<0. 05). The mean BCVA was no statistically significant difference between type II and Ⅲ patients (P>0. 05).?CONCLUSlON:ARPE fundus demonstrated the multiple dark gray discrete lesions, the degree of visual impairment related with the presence of pigment epithelial barrier and lesion location. OCT and FFA characterized three types. FFA is shown asblack light orgrape variety fluorescent spot, and is the basis of diagnosis. OCT can display the lesions organization form of each layer clearly. lt plays a more and more important role in the diagnosis and differential diagnosis of ARPE.

Objective To investigate the impact of accountable and kindred-like nursing and the practice of quality care.Methods 100 primiparas who gave birth three months before the accountable and kindred-like nursing were selected as the control group,while 100 primiparas who gave birth three months after accountable and kindred-like nursing were selected as the observation group.Tow groups' understanding of health education knowledge and skills,satisfaction with nursing when discharged,nomination rate of the most satisfactory nurse and compliance behavior after discharged were compared.Results In the observation group,62 cases had fully understood,28 had basically understood and 10 had not understood the health education knowledge when discharged,while in the control group the numbers were respectively 30,56 and 14.In the observation group,75 cases had fully understood,19 had basically understood and 6 had not understood the health education skills when discharged,while in the control group the numbers were respectively 28,58 and 14.The understanding of health education knowledge and skills were much better in the observation group than in the control group,and the differences were statistically significant (x2 =21.13,44.40,respectively; P ＜0.05).After being discharged,the compliance behaviors including pure breastfeeding,newborn massage and baby swimming of the observation group were also better than the control group (49 vs 27,58 vs 27,47 vs 18,respectively),and the differences were statistically significant (x2 =9.93,20.14,19.16,respectively; P ＜0.05).There were no significant differences in infant buttock nursing between two groups (P ＞ 0.05).The satisfaction of nursing and nomination rate of the most satisfactory nurse were also much higher in the observation group (99 vs 93,82 vs 53,respectively),and the differences were statistically significant (x2 =10.86,19.17,respectively ;P ＜ 0.05).Conclusions Accountable and kindred-like nursing can enhance the effect of health education,compliance behaviors,so as to improve the satisfaction degree of puerperants and their families with nursing service.

OBJECTIVETo observe the effect of volatile oil of amomum (VOA) on the expressions of mastocarcinoma-related peptide (PS2) and platelet activating factor (PAF) in helicobacter pyloriassociated gastritis (HPG) and to analyze its potential mechanism.

METHODSEighty patients with HPG were randomly assigned to two groups, 42 patients in the treated group treated with 0.5 mL VOA, thrice per day; and the 38 patients in the control group receiving Western tertiary medicinal treatment. Gastroscopic picture and helicobacter pylori (HP) infection (by quick urease and Warthin-Starry stain) of the gastro-membrane, expressions of PS2 and PAF (by immunohistochemical assay and Western blotting) as well as the contents of aminohexose and phospholipid (by Neuhaus method) in the gastric membrane of all patients were detected before treatment and 4 weeks after treatment. The clinical efficacy in the two groups was compared.

RESULTSThe total effective rate in the treated group was 88.1%, which was significantly higher than that in the control group (78.9%, P<0.05). After treatment, in the treated group, gastric membranous contents of aminohexose and phospholipid was increased, expression of PS2 elevated but that of PAF lowered, all showing significant difference as compared with those in the control group (P<0.01). In the control group, the expressions of PS2 and PAF changed insignificantly. The radical eliminating rate of HP in the treated group and the control group was insignificantly different between them (76.1% vs. 65.8%, P>0.05).

CONCLUSIONThe mechanism of VOA for anti-gastritis might be related with its action in increasing the expression of PS2 and decreasing the expression of PAF, and thus regulating the hydrophobicity of the gastric membrane.

Salvia miltiorrhiza is a highly valued traditional chinese medicine for the treatment of atherosclerosis-related disorders in china, such as cardiovascular and cerebrovascular diseases in China. The wilt disease is serious in the culture of S. miltiorrhiza. Wilt disease cause biomass of plant shoots and roots is lessened, active components are decreased. To solve these problems, we research the pathogen causing wilt disease of S. miltiorrhiza. The suspected pathogen is identified by morphology and etiological test. The identification was further confirmed by alignment the sequences of internal transcribed spacer (ITS) amplified by PCR. Our result show the wilt disease of S. miltiorrhiza mostly occurred in July and August, which is hot and wetter. The wilt disease rate of S. miltiorrhiza continuous cropping for one year in S. miltiorrhiz stubble is 10%, but the wilt disease rate of S. miltiorrhiza continuous cropping for three years in S. miltiorrhiz stubble is 60%-70%. The root rot of S. miltiorrhiz caused by the wilt disease, so the wilt disease was mistaken for the rot root in production. Morphological characteristics show the pathogen is Fusarium oxysporum. The sequence of ITS wes determined and found by BLAST shared 99% identity to that of F. oxysporum f. sp. cucumerinum. So it comes to the conclusion that the causing agent of wilt disease on S. miltiorrhiza belongs to F. oxysporum.
