Objective To explore the clinical characteristics of the elder patients with the invasive fungal infections (IFI) in gerontal hematological malignant. Methods 38 patients with IFI during Jan 2000 to October 2007 were enrolled to analyze retrospectively. Results A total of 38 cases of gerontal hematological malignancies were diagnosed IFI. Occurrence of IFI correlated with agranulocytosis persistence >5 days, broad - spectrum antibiotics using >7 days, complicating diabetes, the hospitalized day longer than 20 days,chemotherapy scheme combined with glucocorticoids. IFI clinical manifestation varied with different infection sites and different fungal species. Lung was the frequently fungal infection site(25 cases, 65.8 %). The most common fungal subtypes were Candida albicans (14 strains, 38.9 %) and aspergillus (7 strains, 19.4 %).Although amphotericin B and itraconozole were adopted to treat IFI, but there were still 10 cases of patients died because of severe respiratory failure. Conclusion Elder patients with gerontal hematological malignant with a marked increasing mortality of IFI, prognosis was poor. Morbidity concerned with many factors, early prophylaxis or empiric antifungal treatment should be adopt.

Objective: To investigate the relationships between constitutional types of traditional Chinese medicine (TCM) and motion sickness. Methods: A survey of TCM constitutions in ocean sailors participating in a voyage was performed by using the TCM Constitution Questionnaire developed by Beijing University of Traditional Chinese Medicine, while the survey of motion sickness was operated by Graybiel's diagnostic criteria. The incidences of motion sickness among sailors with different types of constitutions were compared. Results: Prior to the voyage, 50.3% of sailors exhibited a gentleness constitution, 14.5% were of dampness-heat constitution, 10.3% were of qi-stagnation constitution, whereas the percentages of qi-deficiency, yang-deficiency, yin-deficiency, blood-stasis and special diathesis constitutions were 6.2%, 7.6%, 6.2%, 4.1% and 0.7%, respectively. None exhibited a phlegm-dampness constitution. By the end of the 176-day voyage, the percentages of gentleness, dampness-heat, qi-depression, qi-deficiency, yang-deficiency, yin-deficiency, blood-stasis, special diathesis and phlegm-dampness constitutions were 33.8%, 13.8%, 13.1%, 11.0%, 6.9%, 9.7%, 4.1%, 0.7% and 6.9%, respectively. The incidence of motion sickness was 69.7% (101 sailors) during this voyage. The incidences of motion sickness among sailors with different types of constitutions before the voyage showed significant difference (P<0.001). The incidence of motion sickness was higher in the sailors with dampness-heat constitution than in those with gentleness constitution. Conclusion: Types of Chinese medical constitution can be related to susceptibility to motion sickness. Furthermore, ocean voyage may have an effect or influence on the type of Chinese medical constitution of sailors involved.

Objective Compare the three kind of criteria in evaluating the incidences of postop-erative cognitive dysfunction in non-cardiac surgery.Methods Four hundred and sixty one non-cardiac surgery patients were randomly enrolled in this study group and two hundred forty four non-surgery patients as control group.Patients??cognitive state was measured on preoperative and postoperative 1 and 3 d by mini-mental state examination(MMSE).POCD was assessed by patients??education level, one standard deviation and Z-score scale,respectively.Results On the first and third day after sur-gery,Z-score scale assess POCD result showed the highest relevance ratio and 95%CI as well as the lowest education level.The education scale showed the lowest incidence of POCD.Education level criteria was positive on postoperative 1 and 3 day,while one case on postoperative 1 day and four cases on postoperative 3 day were negative by Z-score scale.Conclusion The incidence of POCD in same pa-tients by three kind of criteria are different.The Z-score scale is recommended to evaluate the POCD in order to avoid misdiagnosis.

Objective To explore the association of galactose-deifcient IgA1 levels with clinical features, and further to provide guidance for individualized treatment of HSP. Methods According to the clinical symptoms and curative effect, 57 children with HSP were divided into four groups:non-HSPN group (n=26), HSPN group (n=7), refractory HSP group (n=7) and remission group (n=17). In non-HSPN group, 12 cases received glucorticoid therapy and 14 cases did not. Serum galactose-de-ifcient IgA1 (Gd-IgA1) concentrations were detected using a Helix aspersa-lectin-based enzyme-linked immunosorbent assay (ELISA), and the total IgA1 levels were measured by ELISA. Results The serum Gd-IgA1 level was signiifcantly higher in 40 HSP children who were not cured than that in remission group and control group (P<0.05). However, there was no difference in Gd-IgA1 level between remission group and control group (P>0.05). Compared with the control group, the serum Gd-IgA1 level was signiifcantly higher in HSPN group, non-HSPN group and refractory HSP, and children with refractory HSP had signiifcantly higher Gd-IgA1 level than children in non-HSPN group (P<0.05). No signiifcant difference in Gd-IgA1 level was found either between HSPN group and refractory HSP group or between HSPN group and non-HSPN group (P>0.05). Furthermore, in non-HSPN group, the serum Gd-IgA1 level in HSP children who were not treated with glucorticoid was signiifcantly higher than that in HSP children treated with glucorticoid (P<0.05). Conclusions The serum Gd-IgA1 level is associated with the disease activ-ity and curative effect of HSP, especially in children with refractory HSP, and it is thus likely to be a new non-invasive disease activity marker for guiding the proper usage of glucocorticoid and immunosuppressants in HSP children.

CONCLUSION: The method is simple,accurate with a good recovery and repeatability and can be used to control the quality of Rhizoma Coptidis and Jinqi Jiangtang Tablet.

Objective To compare the effects of methods of general anesthesia on postoperative cognitive function in patients undergoing non-cardiac surgery. Methods One thousand ASA Ⅰ or Ⅱ patients, aged 18-60 yr, undergoing non-cardiac surgery were randomly divided into 5 groups ( n = 200 each) : isoflurane + propofol + fentanyl group (group IPF); isoflurane + remifentanil group (group IR) ; sevoflurane + propofol + fentanyl group (group SPF) ; sevoflurane + remifentanil group (group SR) ; propofol + remifentanil group (group PR) . Two hundred non-operative patients served as control group (group C) . In groups IPF and SPF, anesthesia was maintained with inhalation of 1.68% isoflurane or 1.71 % sevoflurane, TCI of propofol with the target plasma concentration of 2-5 μg/ml, and intermittent iv boluses of fentanyl. In groups IR, SR and PR, anesthesia was maintained with inhalation of 1.68% isoflurane or 1.71% sevoflurane, or TCI of propofol with the target plasma concentration of 2- 5 μg/ml, and TCI of remifentanil with the target plasma concentration of 2-6 ng/ml. The patients' cognitive function was assessed using mini-mental state examination (MMSE) at 1 d before operation, while leaving postanesthesia care unit (PACU) , and at 1 and 3 d after operation. The Z score was used to identify the cognitive dysfunction as recommended by Moller while leaving PACU, and at 1 and 3 d after operation. Results Compared with group C, the MMSE score was significantly decreased while leaving PACU , and the incidence of cognitive dysfunction increased while leaving PACU and at 1 d after operation in the other groups ( P ＜ 0.05). Compared with groups IPF,IR,SPF and PR, the incidence of cognitive dysfunction was significantly increased in group SR ( P ＜ 0.05) . Conclusion General anesthesia with sevoflurane combined remifentanil exerts less effect on the postoperative cognitive function in patients undergoing non-cardiac surgery.

Aim To investigate the effect of curcumin on radiosensitivity of radioresistant nasopharyngeal carcinoma cell line CNE-2R and its mechanism.Methods The concentration of curcumin was screened by MTT assay.Dose-survival curves were obtained according to the colony forming test for L-Q matching and multitarget-single hitting matching,while SF2 and the correlation parameters of radiation biology were calculated.The changes of cell cycle in CNE-2R cells caused by curcumin were also tested by flow cytometry(FCM).The differential expression of genes related to cell cycle and DNA damage repair were detected by RT-qPCR.Results CNE-2R cells could not be inhibited by 10 μmol·L-1 curcumin.Dealt with 10 μmol·L-1 curcumin for 24 h,the value of α/β increased to 1 596 from 6.56;the value of SF2 decreased to 0.361 Gy from 1.93 Gy;the value of N decreased to 1.06 from 1.60;the value of D0 decreased to 2.12 from 3.27;the value of Dq decreased to 0.12 from 1.53.FCM showed that the cells in G2 phase had a significant increase and the cells in S phase had a significant decrease after dealt with 10 μmol·L-1 curcumin for 24 h.The expression of CDK4 was significantly up-regulated and GADD45g,BRCA1 were significantly down-regulated.Conclusion Curcumin radiosensitizes nasopharyngeal carcinoma cell line CNE-2R by changing cell cycle and affecting DNA damage repair through regulating the expression of CDK4,GADD45 g and BRCA1.

OBJECTIVE: To assess the labial and lingual alveolar bone thickness in adults with maxillary central incisors of different inclination by cone-beam computed tomography (CBCT). METHODS: Ninety maxillary central incisors from 45 patients were divided into three groups based on the maxillary central incisors to palatal plane angle; lingual-inclined, normal, and labial-inclined. Reformatted CBCT images were used to measure the labial and lingual alveolar bone thickness (ABT) at intervals corresponding to every 1/10 of the root length. The sum of labial ABT and lingual ABT at the level of the root apex was used to calculate the total ABT (TABT). The number of teeth exhibiting alveolar fenestration and dehiscence in each group was also tallied. One-way analysis of variance and Tukey's honestly significant difference test were applied for statistical analysis. RESULTS: The labial ABT and TABT values at the root apex in the lingual-inclined group were significantly lower than in the other groups (p < 0.05). Lingual and labial ABT values were very low at the cervical level in the lingual-inclined and normal groups. There was a higher prevalence of alveolar fenestration in the lingual-inclined group. CONCLUSIONS: Lingual-inclined maxillary central incisors have less bone support at the level of the root apex and a greater frequency of alveolar bone defects than normal maxillary central incisors. The bone plate at the marginal level is also very thin.
