This article proposed a new cognition on the duration of asymptomatic HIV infective stage.It expounded the reason for treating AIDS with TCM first choosing asymptomatic HIV infective stage from the views of "preventive treatment of disease" and treatment based on syndrome differentiation.

In this article,we discussed the limitations of present clinical teaching situation, which included curriculum concept, clinical practice condition and quality of teachers. Based on the analysis of present education,we should constitute effective teaching mode,set curriculum system reasonably and take effective teaching means in the clinical teaching of laboratory medicine. It’s very important for educate students with practice talent and high integrative quality.

This study was aimed to analyze the medication rules of AIDS fever by Professor Li Fazhi, in order to pro-vide the corresponding medication reference basis for Chinese medicine treatment of AIDS fever. The complex net-work analysis method was used. This study was conducted among AIDS fever patients treated by Professor Li Fazhi from September 2007 to June 2012 in Weishi County, Henan Province. The analysis was made on the etiology and pathogenesis of AIDS fever, syndrome differentiation and treatment as well as medication of senior famous Chinese medicine doctors. The results showed that through a multidimensional query analysis, the core medication in the treatment of AIDS fever included harmonization and heat-clearing herbs such as Bupleurum, Licorice, Scutellaria, as well as qi-supplementing and healthy qi reinforcing herbs such as Codonopsis and Astragalus. The core prescriptions were modified Xiaochaihu Decoction and Buzhong Y iqi Decoction. It was concluded that the treatment rules of AIDS fever by Professor Li Fazhi was to clear heat in combination with supplementing the center and boost qi.

OBJECTIVE To study the effect of age on tympanoplasty. METHODS The preoperative pure tone hearing threshold was 55dB in the aged group and 39 dB in the medium aged group. All patients, includ-ing 24 with chronic suppurative otitis media, 29 with cholesteatoma otitis media and 27 with chronic silent otitis media and/or tympanosclerosis, underwent radi-cal mastoidectomy and tympanoplasty (typeⅠfor 25 ears, modified type Ⅱfor 23 ears and modified type Ⅲ for 32 ears) under general anesthesia. RESULTS The average air-conductive hearing threshold was 46dB in the aged group (healing rate was 67 %) and 33dB in the medium aged group (healing rate was 70 %). With aging, the average air-conductive hearing threshold in-creased (P

Objective To investigate the significance of miR-103 as noninvasive biomarker for diagnosis of nonalcoholic fatty liver disease (NAFLD).Methods The serum samples were collected from healthy subjects and NALFD patients to detect biochemical parameters.NucleoZOL method was used to isolate serum miRNA.SYBR Green qPCR was used for relatively quantitative analysis of miR103a-2.The correlations between miR-103a-2 and biochemical parameters were analyzed by Spearman method.Results Compared with healthy control group,the levels of total cholesterol (TC),triacylglyceride (TG),alanine aminotransferase (ALT) and glutamyl transpeptidase (γ-GGT) were all significantly increased in NAFLD group (P ＜ 0.01).Compared with the NAFLD group accompanying ortholiposis,the levels of TC,TG and low density lipoprotein-cholesterol (LDL-C) were all significantly increased in the NAFLD group accompanying dyslipidemia (P ＜0.01).Compared with the healthy control group,the level of serum miR-103a-2 increased in both NAFLD with ortholiposis group (P ＜ 0.05) and NAFLD with dyslipidemia group (P ＜ 0.01).The level of serum miR-103a-2 was positively correlated with serum TC (r =0.495,P =0.001).Conclusion Serum miR-103a-2 may be a more sensitive parameter for noninvasive screening of NAFLD than the parameters of blood lipid.

Objective To evaluate the efficacy and safety of oral prednisone in patients with relapsing neuromyeli?tis optica. Methods Seventeen patients with relapsing neuromyelitis optica receiving long-term oral prednisone had been followed. The Expanded Disability Status Scale (EDSS) and annualized relapse rates were used to evaluate curative effect. Results During long-term oral prednisone treatment, patients had a significant reduction in the EDSS [(3.09 ± 0.85) vs. (4.06 ± 0.80), P<0.05] and the median annualized relapse rate was significant reduced [(0.34 ± 0.31) vs. (1.51 ± 0.57), P<0.005]. But the effect of different dosage of prednisone on annualized relapse rates was not different. No severe adverse re?actions were observed. Conclusions Treatment with long-term oral prednisone in patients with NMO significantly reduces relapse rates, improves neurological function and the treatment was well-tolerated.

Objective To compare the sensitivities of the stimulation effect of human cord blood mesenchymal stem cells(CB-MSCs) and CB-MSCs of neuronal differentiation to lymphocytes(LCs) detected with carboxyfluorescein didcetate(CFSE) and MTT. Methods To prepare LCs from SD rat and divided into four group stimulating cells: 1. CB-MSCs;2. Dif-CB-HSCs;3. SH-SY5Y(positive control);4. Auto-LC(negative control).Stimulating cells were respectively Co-cultured with LCs. The proliferation of LCs was detected with MTT and CFSE ( n =3). Results CB-MSCs and Dif-CB-HSCs stimulated LCs to proliferate more weakly than positive control detected with MTT and CFSE. The quantity of proliferation of lymphocytes Co-cultured with CB-MSCs and Dif-CB-HSCs were higher than that of Auto-LC detected with CFSE. But MTT OD value of CB-MSCs and Dif-CB-HSCs was a little lower than that of Auto-LC. Statistical analysis results showed no significant difference.Conclusion CFSE can reflect proliferation status of lymphocytes better than MTT. CFSE shows more advantages in practical use.

Objective To explore the potential correlation between fluoride levels of urine and influencing factors in water-high-fluoride areas.Methods In 2010,based on plain area,mountainous area and mixed area (altitudes were 898,2 200,1 460 m,respectively),3 villages of water-high-fluoride areas were selected by purpose sampling;pupils' family members were selected as survey population by cluster sampling.Questionnaire was conducted to collect general information;fluoride contents in urine and drinking water were measured using ionselective electrode.A linear multiple regression was used to examine which factors affected urinary fluoride.Results Totally there were 968 people distributed in plain area (444),mixed area (368) and mountainous area (156),medians of urinary fluoride level were 0.71,1.59 and 1.67 mg/L,respectively,the difference was significant (F =203.90,P ＜0.01);medians of water fluoride level in the three different habitats were 0.50,1.00 and 3.50 mg/L,respectively,the difference was significant (F =331.98,P ＜ 0.01).Age,gender,fluoride contents in drinking waters and habitat explained 33.1％ of urinary fluoride variation.Male had higher urine fluoride than female,older age and higher level fluoride in drinking water contributed to higher fluoride level in urine,higher altitude contributed to higher urinary fluoride.Conclusion Once fluoride content in urine is used to estimate fluoride exposure level among people in high fluoride area,gender and age must be taken in consideration.

Objective To investigate the efficiency of levodopa in dopa responsive dystonia (DRD) patients and drugs safety in pregnancy cases confirmed by genetic detection.Methods The clinical characteristics of two patients were analyzed.Direct sequences were performed in guanosine triphosphate (GTP) cyclohydrolase Ⅰ (GCH1) gene and tyrosine hydroxylase (TH) gene mutation screening.Results Case 1 was a young man exhibiting writer's cramp and dystonia of lower legs with marked diurnal fluctuation.Writer's cramp could not be relieved by treatment of low dose levodopa/benserazide.After increasing dose,the symptom of writer's cramp appeared occasionally.Case 2 was a young woman who experienced gait disorder.The symptom disappeared completely by levodopa treatment.She used levodopa and benzhexol during pregnancy.By 38 gestational weeks,she gave birth to a healthy baby.Sequence analysis of GCH1 gene in case 1 revealed a mutation (c.230C ＞ G p.S77C) that is a novel pathogenic mutation.The confirmed mutation c.628delC (p.His210Thrfs* 5) found in case 2 had been reported previously.No mutations in TH gene were detected in two patients.Condnsions Most of DRD patients have dramatic response to levodopa,but patients exhibited writer' s cramp may respond to levodopa incompletely.The previous reports indicate that no adverse events have been reported in DRD pregnant women with the monotherapy of levodopa.
