Objective To explore the influence of studying in the elderly university on the cognitive function for elderly. Methods Elderly university group (EUG) was consised of 105 subjects aged ≥60 who studied in the elderly university for one year. Controlled group(CG) was consisted of 105 elderly over 60 years of age who were siblings for subjects and would not studied in elderly university. Meanwhile, it was excluded if they were working. Two groups were excluded depression patients before study. The assessment tools were composed of Center for epidemiological survey of depression scale (CES-D), activity of daily living scale(ADL), mini-mental state examination (MMSE)and Wechsler's adult intelligence scale(WAIS). There were no significant statistics difference in scales of CES-D, ADL, MMSE and WAIS between two groups. Results There were no significant statistics difference of CES-D, ADL and MMSE between two groups after a year, however, the scales of ADL for controlled group after one year was higher than that before one year( t = 2. 191, P = 0.031 ). The MMSE mark shows one(0.95% )sustain cognitive impairment in EUG after one year; meanwhile there were six elders of (5.77%)come up to critical value of cognitive impairment in CG, the difference was almost statistical significance (P=0. 058 ). The WAIS mark demonstrated the total scale, VQ scale and PQ scale was declining. The score of total scale and perform scale of WAIS in CG were (110.3 ±8.2 )and (110.9 ±7.7) respectively. The score of total scale and perform scale of WAIS in CG were ( 107.8 ± 9.6 ) and ( 107.9 ± 13.4 ) respectively. There were significant difference between two groups(P=0. 044, P=0. 049). Furthermore, after one year the score of total scale of WAIS in CG( 110. 6 ± 7.4 ) outstanding be lower than that one year ago(P = 0. 022 ). There was no significant means for the total scale , verbal scale and perform scale of WAIS in CEG before and after year.Conclusion The program of continue education may play a positive role to stay or to improve the descending of the cognitive function in the elderly.

Background and purpose: L-asparaginase (L-Asp) is an important drug in the treatment of childhood lymphoid neoplasms at present, but a lot of adverse reactions of L-Asp were observed. Pegasparaginase (PEG-Asp) is available in China in recent years. This study aimed to explore efifcacy and side-effect of PEG-Asp as ifrst-line treatment in childhood acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). Methods:A total number of 211 ALL or LBL patients were treated with CCLG 2008 or BFM-90 protocol with PEG-Asp or L-Asp between Apr. 2008 and Mar. 2013;42 patients, among whom, were 35 ALL patients and 7 LBL patients, were treated with PEG-Asp as ifrst-line treatment;169 patients were treated with L-Asp as ifrst-line treatment (including 53 patients treated with L-Asp during induction protocol; with PEG-Asp during consolidate protocol). The clinical outcome and adverse reaction of PEG-Asp with L-Asp were observe and compared. Results: There were 35 ALL patients in PEG-Asp ifrst-line treatment group and the complete remission rate after 1 course of PEG-Asp was 97.1%,however, which was 83.3%of high risk ALL patients. The complete remission rate of 7 LBL patients of PEG-Asp ifrst-line treatment group was 57.1%. There was no signiifcant difference between 2 groups (P>0.05). Thirty-four patients relapsed including 5 patients of PEG-Asp ifrst-line treatment group, 16 patients of L-Asp ifrst-line treatment group and 13 patients treated with L-Asp during induction protocol and with PEG-Asp during consolidate protocol. Thirty-one patients died including 3, 18, 10 patients in 3 groups respectively. Twenty-two patients died of relapse, 4 died without remission, 5 died of complications. There was also no signiifcant difference between 2 groups (P>0.05). The incidence rates of adverse reactions were 47.6% and 63.3% respectively. Anaphylaxis, liver functions abnormalities, blood coagulation abnormalities, gastrointestinal reaction, hyperglycemia and pancreatitis were common in our patients. The incidence rate of anaphylaxis in PEG-Asp as ifrst-line treatment group was lower than other groups (P=0.03). But there was no signiifcant difference been observed in the incidence of other adverse reaction. Conclusion: The short-term efifcacy of PEG-Asp as the ifrst-line treatment in childhood leukemia and lymphoma was satisfactory and the incidence rate of anaphylaxis was lower. However, we will still pay much attention to adverse reaction monitoring of PEG-Asp.

BACKGROUND: Panel reactive antibody (PRA) can mediate hyperacute rejection, and lead to decrease in success rate of transplantation and survival rate of renal graft in highly sensitized recipients compared to non-sensitized recipients.OBJECTIVE: According to human leucocyte antigen (HLA) cross-matching standards to select suitable donors for sensitized recipients and to evaluate the incidence of acute rejection and survival rate of renal allografts.DESIGN: Case observation.SETTING: Zhujiang Hospital of Southern Medical University.PARTICIPANTS: 136 sensitized recipients with positive PRA underwent renal transplantation in Department of Organ Transplantation, Zhujiang Hospital of Southern Medical University between January 1997 and December 2003 were selected, including 41 males and 95 females, aged (45±9) years. Recipients of first, second, third, and fourth transplant were 115, 18, 2 and 1 case, respectively. The informed consent was obtained from all patients. The protocol was approved by Hospital Ethics Committee. Lambda antigen tray (LAT) and LAT-Mix were purchased from One Lambda, Inc, USA. Special monoclonal tray -Asian HLA class Ⅰ (SMT72R) and Micro SSP Generic HLA Class Ⅱ (DRB/DQB) were also purchased from One Lambda, Inc, USA.METHODS: Pre-operative PRA levels and specificity of recipients were detected by ELISA test with Lambda antigen tray (LAT). Donor and recipient HLA class Ⅰ typing was performed with special tray - Asian HLA class Ⅰ (SMT72R), and HLA class Ⅱ gene typing with Micro SSP Generic HLA Class Ⅱ (DRB/DQB) (Micro-SSP). HLA-matching between donor and recipient was performed according to HLA cross-reactive group (CREG) standards by UNOS and class Ⅱ antigen permissible mismatch. The incidence of acute rejection and survival rate of renal allografts were evaluated within 1, 3 and 5 years.MAIN OUTCOME MEASURES: ①PRA levels and specificity of sensitized recipients before and after transplantation; ②HLA-matching between donor and recipient; ③Incidence of acute rejection and survival rate of renal allografts after transplantation.RESULTS: 136 PRA positive sensitized recipients were all included in final analysis. ① There were 104 recipients with anti-HLA class Ⅰ IgG antibody, 76 with anti-HLA class Ⅱ IgG antibody, and 44 with both anti-HLA class Ⅰ and Ⅱ IgG antibodies in 136 recipients. ②The number of cases of 0, 1, 2, 3, and 4 mismatch (MM) was 7, 26, 47, 39 and 17, respectively by the standard of conventional HLA antigen matching; However, the number of the recipients with 0, 1, 2, 3, and 4MM was 31, 53, 36, 16, and 0, respectively according to the principle of HLA CREG matching. ③By the principle of HLA CREG matching, rates of acute rejection in sensitized recipients with 2MM and 3MM HLA-CREG were significantly higher than those with 0MM (P < 0.05). Renal allograft survival rate in sensitized recipients with 0MM was significantly higher than those with 2MM and 3MM (P < 0.05).CONCLUSION: ①HLA CREG matching can significantly improve the ratio of well-matched. ② Good HLA matching can reduce the incidence of acute rejection in sensitized recipients and increase the survival rate of renal grafts.

Objective To investigate the effects of melatonin on choline acetyltransferase (ChAT) in rat hippocampus after isoflurane anesthesia. Methods Sixty male SD rats weighing 390 - 440 g were randomized into 5 groups (n = 12 each): control group (group C), 1% isoflurane group (group Ⅰ), 1% isoflurane + melatonin group (group IM) , 2% isoflurane group (group J) and 2% isoflurane + melatonin group (group JM) . In IM and JM groups, melatonin 10 mg/kg was administered intraperitoneally once a day for 7 consecutive days, while equal volume of normal saline was given intraperitoneally instead of melatonin in C, I and J groups. Groups Ⅰ and IM inhaled 1% isoflurane and groups J and JM 2% isoflurane for 4 h on 7th day. All the rats underwent Morris water maze test on the day after anesthesia for assessment of learning and memory ability (escape latency and probe time) . The training test was performed 4 times a day for S days. Six rats randomly selected from each group were sacrificed the end of the test. The blood samples were collected for detection of plasma melatonin level by ELISA.The brain tissues were removed for determination of the expression and activity of ChAT in hippocampus by Western blot or colorimetric assay. The left rats were selected and sacrificed for determination of the number of ChAT positive neurons in hippocampal CA1 region and entate gyrus by immunofluorescence. Results The plasma melatonin level and expression and activity of ChAT were significantly lower in group I than in group C ( P ＜ 0.01) . The escape latency was significantly longer, the probe time was significantly shorter, and the plasma melatonin level and expression and activity of ChAT were significantly lower in group J than in group C ( P ＜ 0.05 or 0.01) . The escape latency was significantly shorter, the probe time was significantly longer, and the plasma melatonin level and expression and activity of ChAT were significantly higher in group IM than in group Ⅰ ( P ＜ 0.05 or 0.01). The escape latency was significantly shorter and the plasma melatonin level and ChAT activity were significantly higher in group JM than in group J ( P ＜ 0.05 or 0.01) . The results of immunofluorescent staining showed that the number of ChAT positive neurons in hippocampal CA1 region and dentate gyrus wag consistent with the changes in the measured ChAT expression. Conclusion Melatonin can reduce isoflurane-mediated inhibition of ChAT expression and activity and thus improve spatial memory impaired by isoflurane anesthesia in rats.

Although the essential oil of Xiangfu Siwu decoction (XFSWD) has strong pharmacological activity, its special physical and chemical properties restrict the clinical application and curative effect. In this paper, Xiangfu Siwu decoction essential oil (XFS-WO) was prepared by forming inclusion complex with β-cyclodextrin (β-CD). The present study is to investigate the effect of β-CD inclusion complex on the transport of major components of XFSWO using Caco-2 cell monolayer model, thus to research the effect of this formation on the absorption of drugs with low solubility and high permeability, which belong to class 2 in biopharmaceutics classification system. A sensitive and rapid UPLC-MS/MS method was developed for simultaneous quantification of senkyunolide A, 3-n-butylphthalide, Z-ligustilide, dehydrocostus lactone and α-cyperone, which are active compounds in XFSWO. The transport parameters were analyzed and compared in free oil and its β-CD inclusion complex. The result revealed that the formation of XFSWO/β-CD inclusion complex has significantly increased the transportation and absorption of major active ingredients than free oil. Accordingly, it can be speculated that cyclodextrin inclusion complex can improve bioavailability of poorly water-soluble drugs. Above all these mentioned researches, it provided foundation and basis for physiological disposition and pharmaceutical study of XFSWD.
