Using a H₂O₂-induced BRL cell senescence model, we investigated the anti-aging effects of drug-containing serums of Erzhi Wan (EZW) and various polar extracts (petroleum ether, ethyl acetate, n-butanol, water, and iridoid glycoside-enriched fractions). Cell viability was detected by MTT assay. Cell senescence was evaluated with β-galactosidase staining assay. Intracellular reactive oxygen species (ROS) were measured by flow cytometry. UFLC-Q-TOF-MS/MS was used to identify chemical components in EZW and the extracts, and molecular docking technology was used to predict the anti-aging components of EZW. Results showed that treatment of cells with 600 μmol·L^-1 H₂O₂ for 72 h markedly induced cell senescence, inhibited cell proliferation and increased intracellular β-galactosidase activity and ROS levels. If cells were pretreated with drug-containing serum of EZW this induction of senescence was decreased. A total of 49 chemical compounds were identified in EZW by liquid chromatography-mass spectrometry, 14 of these were identified by molecular docking as potential active ingredients. Based on these analyses, and the in vitro experiments with polar extracts, we conclude that the anti-aging components of EZW are triterpenes, flavonoids and phenyl alcohols, providing a basis for further elucidation of the active agents and mechanism of the anti-aging effect of EZW.

OBJECTIVETo analyze the prevalence, clinical features, diagnosis, potential risk factors, anti-tuberculosis treatment efficacy and prognosis of the patients with leukemia complicated with active tuberculosis (TB).

METHODSA retrospective study was performed to analyze the clinical characteristics, relevant examination data, diagnosis methods and follow-up data about 44 leukemia cases complicated with active TB from January 2006 to December 2011 in our single center.

RESULTSThe prevalence of leukemia complicated with active TB was 1.70% (pulmonary TB 1.35%, extra-pulmonary TB 0.35%) and no statistically significant difference was found between each subgroup of acute and chronic leukemia groups (P>0.05). Most of the patients were men, with a male to female ratio of 2.14:1, the median age of 40 years old (range 16 to 78), presenting as atypical clinical manifestations, such as high fever, cough, and so on. Eighteen patients (40.9%) were diagnosed with definitely etiological evidence while the other 26 patients (59.1%) were diagnosed clinically. The extra-pulmonary TB group had a higher purified protein derivative (PPD) test positive rate than that of the pulmonary TB group (88.9% vs 42.9%, P=0.020). The chest CT and T-cell spot of tuberculosis test (T-SPOT.TB) were helpful tools for diagnosis. The potential risk factors included age, sex, nutritional status, neutropenia, decreased cellular immunity, type and course of leukemia, etc. The significant differences in age, gender, administration route of immunosuppressive drugs were found between neutropenic and non-neutropenic groups (P<0.05). The efficacy of first-line anti-tuberculosis therapy was 83.7% and the total course to cure TB was around 12 months. Four patients were dead due to pulmonary TB with a 9.1% attributable mortality.

CONCLUSIONThe prevalence of leukemia complicated with active TB is higher than the general population in our single center. The main characteristics including various potential risk factors, atypical clinical features, diagnoses mainly made by clinical features were found in our patients with leukemia complicated with active TB. However, it showed that these patients demonstrated good responses to the first-line anti-tuberculosis therapy and relative lower attributable mortality.

The questionnaire and the result of 2010' Hwato Cup National University Students' Acupuncture Manipulation Skills Competition were analyzed in this paper. It was showed that the competition achieved the significant effects of enhancing acupuncture manipulation skills for the university students and promoting the standardization on teaching acupuncture manipulation skills. The teachers and students were not very satisfied with the current acupuncture manipulation skill education. In the competition, only the item of reciting the classics achieved more than 90 scores, which just displayed the memory ability. The results of the manipulation competition were generally not very high. It is suggested that concerning to teaching acupuncture and moxibustion in the future, the ratio of class time for improving the practice ability on the human body should be increased and the practice on some manipulation techniques such as inserting the needle by holding the needle tip with the pressing hand, reinforcing-reducing technique by twirling and rotating the needle and warming needle technique should be intensified. It is necessary to enhance the interpretation, emphasis and supplementation on the keys and details of some manipulations of acupuncture and moxibustion.

Objective To study the characteristics and influencing factors on hearing impairment among elderly population in the community of Taiyuan city. Methods 384 ageing people above 60 years old were selected from Chaoyang and Guandi community in Taiyuan city by multi-stage sampling. Data on influencing factors of hearing impairment were collected by questionnaire. 5 ml fasting blood samples were drawn to detect the level of glucose, triglyceride and cholesterin in the blood samples. All the objects were tested with binaural hearing. The level of binaural hearing threshold at 0.5 kHz, 1 kHz, 2 kHz, 3 kHz, 4 kHz, 8 kHz were measured by GVSLN-TC-GK2000 hearing-assistant evaluative apparatus. The level of 3 kHz, 4 kHz, average hearing threshold from ear with better audition was chosen as dependent variable. Socio-demographic data, environmental factors and biochemical indicator were chosen as independent variables, t test, ANOVA and accumulative logistic regression were performed to analyze the influencing factors on hearing impairment by software SPSS 13.0. Results The prevalence of hearing impairment among elderly population was 90.9%. The hearing disorder was 78.6% with 1.3% of them using hearing-assistant apparatus. Results from single factor analysis showed that the average levels of 3 kHz, 4 kHz, 8 kHz hearing thresholds were significantly different among elderly with different age, sex, education background and the levels of glucose and cholesterin (P<0.01). Results of accumulative logistics regression showed that except glucosein which was the only one included in regression model of lower median frequency group, all the others were included in regression model of frequency group. Being male, older age and with higher level of glucose and cholesterin in blood were risk factors causing hearing impairment. Higher education level seemed to be a preventive factor. Conclusion Hearing impairment appeared in higher prevalence among the elderly population, suggesting that proper measures should be taken. It is beneficial for abating hearing impairment to decrease the level of glucose and cholesterin in blood.
