Objective To evaluate the effects of Aidi injection on the short-term curative effect,pain level,quality of life and the survival time for the elderly and infirm patients with advanced cancer.Methods A total of 143 elderly patients with advanced cancer were randomly divided into two groups,71 patients in control group were treated with routine support therapies,and 72 patients in treatment group were injected with 50-60 ml Aidi injection infused in NS 250 ml by i.v drip every day combined with routine medicines,each cycle was 21 days,all patients were received for 2 cycles.Results After treatment the short-term curative effect rate (CR+PR) was 2.8 ％ (2/72) only compared with no effect of control group.But the effective and stabilization rate (CR+PR+SD) was 66.7 ％ (48/72),it was 31.0 ％ (22/71) in control group.There was significant difference between the two groups (P ＜ 0.05).The overall effective rate of easement of pain was 67.7 ％ (48/72) in treatment group versus 36.1％ (13/36) in control group (P ＜ 0.05).The median survival time (MST) was 6.2 months in treatment group versus 5.1 months in control group (P ＞ 0.05).The quality of life in treatment group was improved obviously (P ＜ 0.05).The side effects of patients in treatment group were very slight.Conclusions Aidi injection can reduce the cancer pain,improve the quality of life and prolong the survival time of the elderly and infirm patients with advanced cancer.It is safe,and effective to inhibit growth of tumor.It can be recommended widely to clinical use.

Objective To understand the predictors and prognostic significance of cranial nerve impairment in non-acquired immune deficiency syndrome (AIDS) patients with cryptococcal meningitis.Methods A total of 145 non-AIDS patients with cryptococcal meningitis admitted to Huashan Hospital,Fudan University from Jan 2000 to Dec 2010 were reviewed retrospectively.Clinical characteristics,initial antifungal therapies and outcome of these patients were analyzed.Continuous variables were analyzed using t test and categorical variables were compared by x2 test or Fisher's exact test.Multivariate analysis was performed by binary Logistic regressions.Results Out of 145 patients,52 (35.9％) patients had cranial nerve impairment at enrollment.Optic (25/52,48.1％) and oculomotor (22/52,42.3％) nerves were the most commonly involved,followed by auditory (12/52,23.1％),abducens (6/52,11.5％),olfactory (4/52,7.7％) and facial (3/52,5.8％) nerves.The best predictive factor of cranial nerve injury was duration of diagnosis (OR =1.056,95％ CI:1.002-1.111).The risk of cranial injury would increase by 5.6％ with one-week delay of diagnosis.Intracranial hypertension and low cerebrospinal fluid cell count were also the independent predictive factors (both P＜0.05).In the follow-up period,73.3％ patients who had cranial nerve injuries were fully recovered,with a median time of 3 (0.5-24.0) months.The independent predictors of recovery were numbers of nerve involved (OR =0.230,95 ％ CI:0.066-0.800,P=0.021) and amphotericin B (AmB) plus 5-fluorocytosine,triazole antifungal agent therapy (OR=10.317,95％CI:2.086-51.025,P=0.004).Conclusions Cranial nerve impairment occurs in one-third of non-AIDS patients with cryptococcal meningitis.Delay in diagnosis,intracranial hypertension and low cerebrospinal fluid cell count are independent predictive factors.Less cranial nerve involvement and AmB plus triazole therapy predict recovery.

The present study is to explore the change process and distribution of phosphorylated DARPP-32 (p-DARPP-32) in rat brain including cortex, hippocampus and striatum and to further deduce whether p-DARPP-32 was possibly involved in epilepsy induced by repetitive low doses of pentylenetetrazol (PTZ). PTZ-induced epilepsy model in rat was established with 30 male SD rats randomly divided into 6 groups, control group and five trial groups [PTZ 1 h, PTZ 6 h, PTZ 24 h, PTZ 48 h and PTZ 72 h respectively, after onset of status epilepticus (SE)]. Immunohistochemistry and immunofluorescence double-labeling were used to detect the temporal time change and distribution of p-DARPP-32 expression and to analyze the coexpression of DARPP-32 and p-DARPP-32 in rat brain after the onset of PTZ-induced generalized SE. The results showed that there was a temporal time change of p-DARPP-32 expression in rat brain after the onset of SE. The number of p-DARPP-32-positive cells increased significantly and reached the peaks at the ends of 1 hour and 6 hours after the onset of SE, but decreased at the end of 24 hours. The moderate to strong p-DARPP-32-immunopositive neurons were observed in cortex, hippocampus and striatum, and located in cell cytoplasm and cell nucleus. Further immunofluorescence double-labeling revealed that denser colocalization of p-DARPP-32 and DARPP-32 in the neurons existed in the area mentioned above. Therefore, PTZ-induced SE may cause phosphorylation of DARPP-32 in rat brain. The temporal time change and distribution of p-DARPP-32 suggest that phosphorylation of DARPP-32 may be involved in PTZ-induced epilepsy in rat brain including cortex, hippocampus and striatum, and p-DARPP-32 may play a central role in the onset of SE.

Dengue virus (DENV) envelope [E] protein is the major surface protein of the virions that indued neutralizing antibodies. The domain III of envelope protein (EDIII) is an immunogenic region that holds potential for the development of vaccines; however, the epitopes of DENV EDIII, especially neutralizing B-cell linear epitopes, have not been comprehensively mapped. We mapped neutralizing B-cell linear epitopes on DENV-1 EDIII using 27 monoclonal antibodies against DENV-1 EDIII proteins from mice immunized with the DENV-1 EDIII. Epitope recognition analysis was performed using two set of sequential overlapping peptides (16m and 12m) that spanned the entire EDIII protein from DENV-1, respectively. This strategy identified a DENV-1 type- specific and a group-specific neutralizing epitope, which were highly conserved among isolates of DENV-1 and the four DENV serotypes and located at two regions from DENV-1 E, namely amino acid residues 309-320 and 381-392(aa 309-320 and 381-392), respectively. aa310 -319(310KEVAETQHGT319)was similar among the four DENV serotypes and contact residues on aa 309 -320 from E protein were defined and found that substitution of residues E309 , V312, A313 and V320 in DENV-2, -3, -4 isolates were antigenically silent. We also identified a DENV-1 type-specific strain-restricted neutralizing epitope, which was located at the region from DENV-1 E, namely amino acid residues 329-348 . These novel type- and group-specific B-cell epitopes of DENV EDIII may aid help us elucidate the dengue pathogenesis and accelerate vaccine design.

Objective To screen monoclonal antibodies (mAbs) for early diagnosis of invisive Aspergillus. Methods Monoclonal antibodies against different antigens of Aspergillus fumigatus were produced. The two pairs of combinations of monoclonal antibodies were selected accoring the distinct epitopes and double-antibody sandwich ELISA based on mAbs above were established. The sensitivity and specificity of the methods were analyzed by detecting culture supernatants of clinical isolates and environmental isolatesof Aspergillus. spp, Penicillium Marneffei, Candidas, and serum from animal models and patients. The epitopes recognized by mAbs were identified by immunobotting. Results A total of 32 hybridoma cell lines that stably produced MAbs were obtained. Two double- antibody sandwich ELISAs were established. One method was specific for 19 clinical isolates and environmental isolates of Aspergillus. spp, whereas the other one was specific for the clinical and environmental isolates of Aspergillus fumigatus without cross-reation with other Aspergillus. spp. For the same kind of medium of Aspergillus fumigatus, the sensitivity of the first method was 10 fold higher than the second method. Conclusions The specific mAbs for early diagnosis of invisive Aspergillus were obtained. Antigen recognized by the specific mAbs was mannoprotein with molecular weights of approximately 25 000-75 000. This antigen was potential early diagnostic marker for invasive Aspergillus.

Objective To evaluate the validity and reliability of learning attitude scale among nurses in continuing nursing education in hospital.Methods We designed a nurse learning attitude scale in continuing education on the basis of a learning attitude questionnaire for teacher-training by Jiao Weiting. In July 2015, totally 207 nurses of the Third Hospital of Mianyang who received continuing education in hospital were selected as the research object by cluster sampling method. We investigated their learning attitudes. The reliability of the scale was assessed by Cronbach's α coefficient and test-retest reliability. The validity was assessed by factor analysis and Pearson's correlation.Results The test-retest reliability of the scale were as the following:cogni-tive level (0.82),experience of emotion (0.89),tendency of behavior (0.91),total scale (0.88);Cronbach's α co-efficients were as the following:cognitive level (0.85),experience of emotion (0.94),tendency of behavior (0.83), total scale (0.89). According to the result of Pearson's correlation,the total scale of learning attitude exhibited a positive correlation with cognitive level,experience of emotion and tendency of behavior (P<0.01). Four prin-cipal components were extracted by factor analysis and the constructs of the instrument obtained were consistent with the conceived concept in essence.Conclusions The scale learning attitude could measure the learning attitude of nurses in continuing nursing education with better reliability and validity.

In recent years,hepatocellular carcinoma (HCC) has become one of the serious healththreatening malignancies worldwide,and its incidence and mortality rates continue to rise.Hepatitis B (HBV)is moderately endemic in China,with enormous numbers of HBV-related HCC cases.Although serum alphafetoprotein (AFP) and ultrasound are the major diagnostic methods for HCC,they have limited application for screening out early or small HCC.The current management of HCC is based on tumor size and location,not on suppressing tumorigenesis,and therefore patients are often faced with low 5-year survival and high relapse rates.Recent studies have shown that long-chain non-coding RNAs (lncRNAs) are closely associated with HCC tumorigenesis,which may have considerable utility as new diagnostic marker and treatment target for HCC.Here,we review the application of lncRNAs in the diagnosis,metastasis,treatment,recurrence,and prognosis of HCC.
