OBJECTIVE: About 70% patients with stroke have dysfunction at various degrees in clinic, especially aphasia would affect their social communication and even offer a serious economic load for family and social. This paper aims to summarize the relevant articles on aphasia recovery so as to provide researching evidences in the future. DATA SOURCES: Relevant articles were retrieved from the Medline with the key words of "aphasia, recovery, language, recovery" in English from January 1980 to January 2004. STUDY SELECTION: All articles were selected firstly, those which were related to aphasia recovery were selected, and the non-randomly clinical papers were excluded. The full text of rest was looked up to determine whether they were randomized controlled studies or not. Randomized controlled researches were regarded as inclusion criteria regardless of blind way. DATA EXTRACTION: Among 22 articles on aphasia recovery, 12 were selected according to inclusion criteria and 10 were excluded because of duplicated papers.DATA SYNTHESIS: Recovery of language function was related to sex,age, ducational degrees, characteristics of lesion, range of lesion, duration from episode to language recovery, insight and self redress of language disorder. Therefore, there were various findings and views for previous re searches on mechanism of aphasia recovery. CONCLUSION: There is not uniform conclusion on mechanism of aphasia recovery. Compliance of language function in brain may be a mechanism of aphasia recovery.

Objective To study the expression changes of IL-1β、FN-α6、IFN-γ and TNFR-m18 in peripheral blood within 2 hours in epileptic mice. Methods Semi quantitative real-time PCR was used to test the mRNA expres?sion level of IL-1β、FN-α6、IFN-γand TNFR-m18 in peripheral blood from normal and pilocarpine-induced epileptic mice at different time points (10 min, 30 min, 1 h and 2 h). Results The mRNA expression level of IL-1βincreased at 30 min(1.8±0.07), 1 h(2.9±0.98)and 2 h(1.45±0.11)after pilocarpine-induced status epilepticus comparing with that of control and SE 10 min(0.81±0.09)(P<0.05). The IFN-α6 mRNA expression level was lower at 10 min(0.59±0.05, P<0.05) than that of control. IFN-γmRNA expression level was higher at 10 min(2.85±0.11) than that of control and at oth?er time points during SE(P<0.01). TNFR-m18 mRNA expression level was higher at 1h(2.84±0.15) than that of control, and at other time points during SE(P<0.01). Conclusion The immune system of epileptic state is active, the imbalance of cytokine expression in peripheral blood may be related to the immune pathological process of acute stage of epilepsy.

Objective To compare the safety and effectiveness of power peripherally inserted central catheters (Power PICC) and double cavity central venous catheter (CVC) application in intensive care unit (ICU). Methods 458 cases were reviewed during January to September in 2014 and divided into two groups: Power PICC group (245 cases) and CVC group (213 cases) , and average retention time, successful rate of inserting catheter and the incidence of complications were compared. Results The average retention time of Power PICC group was (21.6±5.8) days which was longer than (13.1±3.4) days of CVC group (t=2.234, P <0.05). No statistics difference of successful rate between two groups (P>0.05). No significant difference for the total incidence of complications between two groups as 14.69% (36/245) and 19.72%(42/213)(P>0.05). No significant difference for the total incidence of complications in the operation time between two groups as 5.31% (13/245) and 4.23% (9/213)(P>0.05). But rate of catheter malposition for Power PICC group [ 2.86% (7/245) ] was higher than CVC group 0 (X2=4.428, P <0.05). Rate of the total incidence of complications in the retention time Power PICC group [ 9.39%(23/245) ] was lower than CVC group [ 15.96%(33/213)(P<0.05). And rate of catheter related blood stream infection of CVC group [3.29%(7/213)] was much more higher than Power PICC group (0)(X2=6.139,P<0.05). Conclusions Power PICC and CVC are both applicable for ICU, and Power PICC has more advantage regarding safety and effectiveness than CVC and can be one replacement for CVC.

Objective To examine the effect of Pu-Erh tea extract(PTE) on genes expression of lipogenesis in white adipose tissue of rats fed high fat diet.Method Thirty male SD rats were randomly divided into three groups(n=10):the control group(basal diet);the high fat group(high fat diet);the PTE group(high fat diet + Pu-Erh tea extract).Body weight and adipose tissue were measured.Expression of genes regulating lipid metabolism was assessed in adipose tissue.Results PTE supplementation prevented diet-induced increases in body weight and adipose tissue.Diacylglycerol acyltransferase-1(DGAT1),stearoyl-CoA desalurase-1(SCD1) and sterol regulatory element binding protein-1c(SREBP-1c) mRNA levels were markedly decreased in adipose tissue of rats fed PTE.Conclusion This study shows for the first time that Pu-Erh tea extract prevents diet-induced obesity,and this effect is partly mediated via a direct influence on adipose tissue.

This paper reported that a new type of floating osmotic pump of ambroxol hydrochloride was designed. Third method apparatus (Chinese Pharmacopeia 2010, appendix XD) was employed to simultaneously evaluate the release and floating behavior in vitro. The system was optimized using central composite design-response surface methodology. Similar factor (f2) between the release profile of self-made formulation and the target release profile was chosen as dependent factor. The amount of glucose (A, mg), pore former (B, %) and weight of coating (C, %) were employed as independent factors. Optimized formulation was: A (100.99 mg), B (1.70%), C (4.21%). The value of f2 (89.14) was higher than that of market capsules (69.02) and self-made tablets (72.15). It was showed that self-made capsules possessed character of zero-order release (r = 0.994 4) and drug release completely (>90%). It was showed in result of in vivo study that tmax and Cmax of self-made capsules were significantly lower than that of market capsules and self-made tablets. The correlation coefficient between the fraction of absorption in vivo and the release rate in vitro was 0.985 1, and relative bioequivalence of self-made capsules was 110.77%. Accordingly, self-made capsules displayed obviously characteristics of controlled release both in vivo and in vitro.

Objective To investigate the expression of serum sHLA-G in systemic lupus erythematosus (SLE) patients and the association with the disease activity.Methods The serum concentration of sHLA-G in SLE patients and healthy controls was measured with enzyme-linked immunosorbent assay.Results Significant higher sHLA-G levels were detected in patients of SLE than control group (P＜0.01),The serum concentrations of sHLA-G in active SLE patients were markedly higher than stable SLE patients (P＜0.01).The expression level of sHLA-G showed positive correlations with SLE activity index (SLEDAI)(r=0.30,P=0.01).There was no correlation between sHLA-G levels and serum concentration of Anti-dsDNA,C3,C4 and Anti-ANA in SLE patients (P＞0.05).Conclusion The level of serum sHLA-G is significantly increased in SLE patients.Positive correlations are observed between sHLA-G levels and SLEDAI.These data indicated that sHLA-G may play certain roles in the pathogenesis and progress in SLE.

Objective:To evaluate the effect and safety of rifabutin combined with multi-drugs in the treatment of multi-drug resist-ant tuberculosis with long-term therapy. Methods:Totally 86 cases of patients with multi-drug resistant tuberculosis were divided into the control group and the treatment group with 43 ones in each according to a random number table method. The two groups were trea-ted with levofloxacin, pasiniazid, ethambutol, protionamide and amikacin etc. The control group was treated with rifapentine, and the treatment group was treated with rifabutin additionally. After 18-month treatment, the negative conversion ratio of sputum smear and sputum mycobacterium tuberculosis culture, lesion absorption rate and cavity closure rate of X-ray chest radiograph and adverse reac-tions in the two groups were compared. Results:The negative conversion ratio of sputum smear and sputum mycobacterium tuberculosis culture in the treatment group was 41. 86% and 32. 56%, respectively, which were similar with those in the control group ( P >0. 05). There were no significant differences in lesion absorption rate and cavity closure rate of X-ray chest radiograph and adverse re-actions between the two groups (P>0. 05). Conclusion:Rifapentine or rifabutin combined with multi-drugs in the treatment of multi-drug resistant tuberculosis can improve the negative conversion rate of sputum mycobacterium and lesion absorption and cavity closure with high safety.
