A variety of opportunistic infections can occur in the late-stage of HIV-1 infection,Mycobacterium avium complex (MAC) infection is a common cause of disseminated bacterial infection. Since the advent of highly active antiretroviral therapy (HAART),the rate of MAC infection has declined substantially,but there is risk in individuals with low CD4 cell counts. This article describes the epidemiological,clinical,therapeutic and preventive aspects of MAC infection in HIV-sero-positive individuals.

Conclusion: In this method the pretreatment is simple and the operation is easy which is helpful in quick and accurate determination.

Objective To analyze the features of intracrayze the features of intracranial cystic diseases on ~1H MRS,and to evaluate the applicable value of ~1H MRS.Methods Fifty-two patients were examinated by single voxel ~1H MRS,included Ⅰ-Ⅱ graded astrocytomas(n=8),glioblastomas(n=9),metastasis(n=13),brain abscesses(n=10),epidermoids(n=4),anachnoid cysts(n=5),brain Cysticerciasis(n=3).Results(1)There was only Lac in Ⅰ-Ⅱ graded astrocytomas.But in glioblastomas,as were as all showed Lac,4 cases showed low Cho and NAA and 2 cases Lip.(2) In(13 metastasis) patients,7 cases only presented Lac,6 cases showed Cho,3 cases showed low NAA and(6 ones) Lip.(3) In brain abscesses,all showed Lac,9 cases displayed AA,6 cases showed Ace,5 cases appeared Suc and Ala,2 cases had Lip.(4) Four cases of epidermoid showed Lac,one showed Lip.In(4 arachnoid) cysts,2 cases had low Lac,one showed Lip.Three cases of cysticerciasis showed Lac,Ace,Suc,Ala and no AA,Cho,NAA.Conclusion Lac is the most common resonance peak on ~1H MRS in intracranial cystic diseases and for no diagnostic specificity.AA combined Ace,Suc,and Ala are highly specificity for brain abscess.Ace,Suc and Ala appearance cues the the possible existence of cysticerciasis.~1H MRS is helpful for the qualitative diagnosis of intracranial disease.

Objective To explore the structure of ribosomal protein S7 ( RPS7) gene of giant panda ( Ailuropoda melanoleuca) and investigate its homologies with other already reported sequences,including Homo sapiens,Mus musculus,Rattus norvegicus and Bos taurus. Methods The cDNA of RPS7 was cloned from the giant panda by RT-PCR. The sequence data were analyzed by GenScan software. Blast 2. 1 was used to study the homology of the obtained RPS7 sequence with the gene sequences of other species; Open reading frame ( ORF) of the DNA sequence was searched using ORF finder software; Protein structure of the RPS7 sequence cloned was deduced using Predict Protein software. Results The full length of the sequence fragment was 589 bp containing an ORF of 585 bp. The deduced protein sequence showed that the protein was composed of 194 ami- no acids and its estimated molecular weight was 22. 126 85 ?103 with a pI of 10. 09. There were 7 different pat- terns of functional sites: one N-glycosylation site; two cAMP and cGMP-dependent kinase phosphorylation sites; four casein kinase C phosphorylation sites; one casein kinase Ⅱ phosphorylation site; two N-myristoylation sites; two amidation sites and one ribosomal protein S7e signature site in the RPS7 protein. Further analysis indicated that the sequence of RPS7 and the protein encoded were highly homologous to some mammals reported.Conclusion The complete coding sequence of RPS7 gene has been cloned through RT-PCR successfully, which is the first report on the RPS7 gene from the giant panda.

Objective To analyze the DWI characteristics of intracranial epidermoid cyst (ECs),and to evaluate “T2 shine-through” effect. Methods There were 15 cases of ECs confirmed by pathology, in which 3 cases had the residual tumor after surgery. The ADC value was measured in ECs,deep white matter and CSF,and the comparison was made between DWI and FLAIR in showing the tumors. Results (1) The lesions in 15 cases were high intensity on DWI, their ADC value was from 0.80?10 -3mm2/s to 1.23?10 -3mm2/s, the average was (1.05?0.14)?10 -3mm2/s. But the ADC value of deep white matter was from 0.74?10 -3mm2/s to 1.09?10 -3mm2/s, the mean was (0.88?0.09)?10 -3mm2/s. The ADC value of CSF was from 2.98?10 -3mm2/s to 3.78?10 -3mm2/s,the mean was (3.31?0.21)?10 -3mm2/s. The ADC value of ECs was significant lower than that of CSF ( P

Objective To assess the effects of health management on high-risk diabetic populations.Methods A total of 307 diabetic high-risk adults from 6 communities of Tianjin were recruited by using diabetes risk screening technology.Three-month intensive health management and nine-month follow-up were conducted in this participants.Paired t test for continuous variables and paired contingency table x2 test were used for data analysis.Results Energy intake (1989.8 vs.1766.4 kcal,t =6.84,P ＜0.05),effective exercises (120.4 vs.157.5 kcal,t =-5.00,P ＜ 0.05),body weight (73.0 vs.71.5 kg,t =6.92,P ＜0.05),systolic blood pressure (130.4 vs.124.6 mm Hg (1 mm Hg =0.133 kPa),t =8.36,P ＜0.05),diastolic blood pressure (81.8 vs.78.4 mm Hg,t =7.40,P ＜ 0.05),serum total cholesterol (5.21 vs.5.08 mmol/L,t =2.73,P ＜ 0.05),fasting plasma glucose (6.4 vs.5.8 mmol/L,t =16.37,P ＜ 0.05)and 2 h postprandial blood glucose (7.7 vs.6.9 mmol/L,t =9.67,P ＜ 0.05) were significantly improved after the intervention.Conclusions Community-based health management may provide an effective way to prevent and control the risk factors of diabetes.

Objective To study the significance and value of imaging typing by analyzing the correlation between contrast-enhanced ultrasound perfusion imaging typing and vascularization in patients with primary hepatocellular cancer.Methods The early enhanced arterial phase reflecting angioarchitecture,and the size and edge of enhanced tumor closely related to microvessel distribution, position and density, were observed and analyzed in 89 patients (113 lesions).All the cases were pathologically proved, and some received immunohistochemisty staining and the microvessel density were recorded.Results The perfusion imagings were classified into 4 types according to changes on contrast-enhanced ultrasound,dendritic,mixed,circular and net-like type.Atypia vessels were commonly seen in dendritic type,and Ⅲ and Ⅳ accounted for 79.1%.The microvessel density was higher than the other types.The circular type was relatively regular and Ⅲ and Ⅳ accounted for 12.5%.The microvessel density was lower than the other types.Combined with the contrast-enhanced ultrasound perfusion imaging and compared with pathological grading,growing methods and microvessel density, the dendritic type was characterized by infiltrative growth, and had strong invasion tendency.The circular type was characterized by expansive growth.And the other two types were characterized by transitional type.Conclusions Contrast-enhanced ultrasound can reflect the angioarchiteeture, the microvessel density and the position,and it is related to the pathological grading and growing methods.
