Objective To investigate the clinical characteristics,diagnosis and therapeutic prognosis of Pneumocystis pneumonia(PCP)in patients with acquired immunodeficiency syndrome (AIDS).Methods AIDS patients with PCP were searched through computer medical record information system,clinical data were analyzed retrospectively,patients were divided into respiratory failure group (n= 1 1 )and non-respiratory failure group (n= 1 2 ),partial pressure of oxygen in arterial blood(PaO2 ),degree of blood oxygen saturation(SaO2 ),CD4+T lymphocyte,and lactate dehydrogenase(LDH) between two groups were compared. Results 23 patients generally had the symptoms of weight loss,oral leukoplakia, shortness of breath,dyspnea,fever,cough,and expectoration. PaO2 value in 23 patients was (78.65±30.85)mmHg,partial pressure of carbon dioxide(PaCO2)was (24.42±5.60)mmHg,pH value was(7.43±0.79),SaO2 was (91.16±9.55)% ;SaO2 and PaO2 in respiratory failure group was lower than non-respiratory failure group,the difference was significant (both P<0.05).Lung computed tomography (CT)scans showed bilateral pulmonary ground-glass-like change. 21 patients used compound sulfamethoxazole tablets,1 patient used compound sulfamethoxazole tablets plus clindamycin,1 patient used only clindamycin,17 patients used glucocorticoid in addition to compound sulfamethoxazole;after treatment,20 patients improved,2 died,and 1 gave up treatment.Conclusion Subacute progressive dyspnea,fever,dry cough,and lung ground-glass-like shadow are common symptoms of PCP in AIDS patients,compound sulfamethoxazole or compound sulfamethoxazole with clindamycin can be used for treatment,glucocorticoid can obviously alleviate the symptoms of patients.

Objective To observe the blocking efficacy of mother to child transmission (MTCT) in pregnant women with positive human immunodeficiency virus(HIV), and explore proper MTCT blocking mode for acquired immunodeficiency syndrome.Methods Clinical data of 23 HIV-positive pregnant women in a hospital from 2005 to 2015 were retrospectively analyzed.Results All 23 HIV-positive pregnant women received highly active antiretroviral therapy (HAART) and comprehensive intervention for blocking MTCT of HIV.Among these women, 12 got pregnant after receiving HAART, 10 were detected positive HIV in early pregnancy (within 28 weeks) and then received HAART, 1 was detected positive HIV 28 weeks after pregnancy and then received HAART.23 HIV-positive pregnant women all delivered normal newborns, follow-up observation of babies found no HIV infection.Conclusion HAART for HIV-positive pregnant women is the key to block MTCT of HIV, combined with preventive medication and artificial feeding of newborns, HAART can effectively prevent MTCT.Mutual blocking mode, such as HAART for HIV-positive pregnant women by specialists, pregnancy check-up, and preventive medicine for infants provided by maternity and child care hospital, is highly efficiency.

Objective To study B lymphocyte subsets(na(?)ve B cells,memory B cells and plas- mablasts)of peripheral blood in patients with rheumatoid arthritis(RA)and its relationship with autoantibod- ies and clinical manifestation.Methods Blood samples and clinical data of 60 patients with RA were enrolled into this study.They were divided into three groups:active,inactive and refractory RA based on clinical mani- festations and 24 healthy controls were included.CD19 and CD27 of B cells in peripheral blood of RA patients and healthy controls were detected using flow cytometry at single-cell level.Frequence of na(?)ve B cells (CD19~+CD27~-),memory B cells(CD19~+CD27~(dim)),plasmablasts(CD19~+CD27~(high))and average fluorescence in- tensity of CD19 were analyzed,and their relationship with clinical manifestations and rheumatoid factor(RF), anti-typeⅡcollagen(anti-CⅡ),anti-cyclic citrullianted peptide(CCP)antibodies were investigatied.Results Frequence of na(?)ve B cells and plasmablasts in peripheral blood of patients with RA was increased compared with normal control.In contrast,memory B cells in patients with RA were decreased.The na(?)ve B cells subset in inactive and refractory RA was higher than that of healthy controls(P＜0.05),and the memory B cells subset in those groups was lower than that of healthy controls(P＜0.05).The plasmablasts in active and refractory groups of RA were higher than those of healthy controls(P＜0.05).The average fluorescence intensity of CD19 in peripheral blood in patients with RA was positively correlated with ESR,C-reactive protein(CRP),healthy assessment questionaire(HAQ),and plasmablasts was positively correlated with arthrocele index.Na(?)ve B cells,memory B cells and plasmablasts subsets had no relation with RF,anti-CⅡand anti-CCP antibodies. Conclusion B cell subsets in peripheral blood of patients with RA are significantly abnormal,characterized by expanded naive B cells and plasmablasts but diminished memory B cells.Plasmablasts are increasesd in active and refractory groups of RA,and have positive correlation with swollen joint index.B cells may play an important rote in the pathogenesis of RA.

Objective To explore the importance of gene diagnosis and prenatal diagnosis of spinal muscular atrophy(SMA),and improve the clinical diagnosis of SMA by analyzing the electrophysiological and gene characteristics of SMA.Methods Fifteen cases with SMA including 9 male and 6 female were enrolled in this study.The age was 5 months to 12 years.The 15 cases were subdivided into 3 clinical types,5 cases of type Ⅰ including 3 male and 2 female aging 5-18 months;7 cases of type Ⅱ including 4 males and 3 females aging 5 months-3 years;3 cases of type Ⅲ including 2 male and 1 female aging 3-12 years.They were all characterized by symmetric muscle weakness(more proximal than distal)associated with atrophy,absence or marked decrease of deep tendon reflexes,loss of voluntary movement and inability to sit or stand.The clinical characteristics and changes of electromyography(EMG)and nerve conduction velocity were assessed in all cases by using Danish Medoc Keypoint myoelectricity and evoked potentials inducer.The survival of motor neuron(SMN)gene was detected by PCR and restriction endonuclease spectrum analysis in 10 cases.Results EMG analysis found 94% patients had spontaneous potential,90% patients had increased duration of motor unit,and amplitude increased in 89% patients.Motor nerve conduction velocity was determined in 78 nerves.Motor nerve compound action potential wave amplitude decreased in 52 nerves,among them,distal latent period prolonged and motor conduction velocity reduced slightly in 36 nerves.Sensory nerve conduction velocity was determined in 45 nerves and remained normal.The SMN gene detection revealed deletion of exon 7 and 8 in 9 cases,deletion exon 7 in 1 case.The SMN gene detection in 10 patients and their parents didn't find any deletion of exon 7 and 8.Conclusions The definite diagnosis of SMA will rely on the typical clinical characteristics,changes of EMG and gene deletion analysis.Gene diagnosis of SMA lays a basis for prenatal diagnosis.
