Objective To study the current cases of Keshan disease aims at providing scientific and basic evidence for prevention and control of the disease. Methods In accordance with historical cases, in 2009, an investigation was conducted in the permanent resident population in seriously infected representative villages of landscapes and ways of living such as Xujialeng, Zhuping and some other adjacent villages in Wudu district, Longnan city. People in those areas were examined and carefully observed based on the scheme of Keshan disease surveillance. Then they were enquired about their medical history, given normal clinical examinations and electrocardiogram(ECG) examination, the suspected cases were chest X-rayed. At the same time, some samples of their hair of some children under 12 and adults were collected to be examined for the selenium content. Results Among the total number of 515 subjects, 20 were diagnosed with Keshan disease with a total detection rate of 3.9% (20/515), among whom 13 were potential patients with a detection rate of 2.5%( 13/515), 7 were chronic patients with a detection rate of 1.4%(7/515). In the total number of 515 ECG, 48 were found with abnormal ECG at a detection of 9.3%(48/515). In the 20 patients, the potential patients were mostly featured with incomplete right bundle-branch block(5 cases), complete right bundle-branch block(3 cases), frequent ventricular premature beat (2 cases) and left ventricle high voltage(2 cases), while the chronic patients were mostly featured with incomplete right bundle-branch block(2 cases). Of the 29 chest X-ray films, 17 cases had heart enlargement with a detection rate of 58.6%( 17/29). The selenium content in the hair of 10 adults and 10 children were (0.38±0.09), (0.31±0.12) mg/kg, respectively. Conclusion There are still existing some cases and obvious virulence factors of Keshan disease in Wudu district, Longnan city.

OBJECTIVE:
To evaluate the function of tubomanometry (TMM) in forcasting the progonosis of acute otitis media with effusion (OME).
METHOD:
We used the technique of TMM to quantify the degree of eustachian tube (ET) dysfunction in 65 patients with OME. The opening of the ET and the transportation of gas into the middle ear were registered by a pressure sensor in the occluded outer ear after applying the stimulus of a controlled gas bolus into the nasopharynx during swallowing. Three excess pressure values were tested subsequently (30, 40, and 50 mbar). If tube opening was registered, the time of opening in relation to pressure applied was measured. The TMM calculated the opening latency index or index R. An R value of < 1 indicated early opening of the tube at the start of application of the stimulus, which was considered optimal. A value > 1 indicated late opening of the tube occurring after the initial stimulus and was interpreted as suboptimal. Inability to calculate the index R value indicated that the tube was unable to actively open at all. The TMM results, were weighted as follows: no R with 0 points, R > 1 with 1 point and R < 1 with 2 points for the measurements at 30, 40, and 50 mbar, respectively. The points of these three tests were added so the ET score (ETS) ranges from 0 (worst value) to 6 (best value). According to the medical history, the patients were divided into two groups, chronic OME group (defined as positive control group), 30 cases with 38 ears; and acute OME group, 35 cases with 46 ears. The healthy ears of all patients were defined as normal control group, 46 cases with 46 ears. The same regular treatments, including classic medical treatments and intratympanic dexamethasone injections, were used to acute OME group in the following 1-2 months. On the basis of therapeutic effect, acute OME group was subdivided into valid group (26 cases with 33 ears) and invalid group (9 cases with 13 ears).
RESULT:
The ETS of normal control group was 5.11 ± 1.32 while it was 1.08 ± 1.32 in positive control group. It was found marked differences between the two groups (P < 0.01). The ETS of both valid and invalid subgroup of actue OME group were significantly lower than normal control group (P < 0.01), but in valid subgroup it was significantly higher than positive control group (P < 0.01), and no marked difference was found between the invalid subgroup and positive control group. After treatments, a significant improvement of the ETS was found in both valid and invalid subgroup (P < 0.05) there was no marked difference between valid subgroup and normal control group. But in invalid subgroup it was still significantly lower than normal cohtrol group (P < 0. 01).
CONCLUSION
TMM could forecast the prognosis of acute OME. Patients with acute OME suffered from ET dysfunction of varied degrees. Those with high ETS could be cured by classic medical treatments and intratympanic dexamethasone injections. But those with poor ETS could not be cured in short period, tube insertion should be considered. If ETS could not be improved by ventilation tube placement, more active treatment, for example, balloon Eustachian tuboplasty (BET), should be used to prevent transforming into chronic OME.

The aim of this study was to investigate the anti-inflammatory effect of Guizhi Fuling capsule and its active complex (consistent of 15 active compounds) on LPS-induced RAW264. 7 cells. The effect of Guizhi Fuling capsule and its active complex on cell viability in RAW264. 7 cells were determined by MTT assay. The inhibitory effect of Guizhi Fuling capsule and active complex on the releasing of IL-1β, TNF-α and PGE2 induced by LPS in RAW264. 7 cells was detected by ELISA assay. The expression of IL-1β and mPGES-1 in Guizhi Fuling capsule or active complex treated RAW264. 7 cells was examined by Western blot assay. Guizhi Fuling capsule and active complex showed no significant effect on the cell viability in RAW264. 7 cells at doses range from 12.5 to 400 mg x L(-1). Compared with LPS treated group, Guizhi Fuling capsule and active complex dose dependently reduced the releasing of IL-1β, TNF-α and PGE2 induced by LPS in RAW264. 7 cells. Moreover, the expression of IL-1β and mPGES-1 was decreased after Guizhi Fuling capsule and active complex treatment, which might contribute to the inhibitory effect of Guizhi Fuling capsule in the releasing of IL-1β, TNF-α and PGE2. This study provided the evidence that Guizhi Fuling capsule and active complex remarkably inhibited the releasing of IL-1β, TNF-α and PGE2induced by LPS in RAW264. 7 cells by reducing the expression IL-1β and mPGES-1. This study provided an experimental basis of Guizhi Fuling capsule for the treatment of inflammation and a theoretical basis for the development of effective compounds of Guizhi Fuling capsule.

Objective To study the relationship between personality and defense mechanism of obsessivecompulsive disorder (OCD) patients.Methods Thirty-four OCD patients were tested with Swedish University Scales of Personality(SSP) and defensive style questionnaire( DSQ), and the result was compared with that of thirty-one normal controls.Results The SSP scores of STA,PsTA,SS,E,TI and M of OCD patients were significantly higher than that of normal controls (t = 2.06 ~ 5.10, P < 0.05 ).Comparing with normal controls, OCD patients tended to use immature and intermediate mechanism such as projection, passive aggression, unconscious emerge, phantasy, withdrawl and reaction formation, but less used mature mechanism such as sublimation, suppression and humor (t = -2.27 ~ 6.73, P< 0.05 ).All subscales of SSP in OCD patients, excluding SD and D, had positive correlation with total score of immature mechanism (r = 0.375 ~ 0.719, P < 0.05 ).The OCD patients' SSP scores of STA had positive correlation with mature mechanism (r = 0.378, P < 0.05 ).The OCD patients' STA, PsTA, I, AS, E, M,VTA and PhTA score of SSP had positive correlation with intermediate mechanism (r= 0.381 ~0.548, P< 0.05 ).All subscales of SSP in OCD patients, excluding SD, had positive correlation with total score of concealment (r =0.342 ~ 0.530, P < 0.05 ).Conclusion OCD patients have the neurotic and aggressive features of personality;and the personalities of OCD patients have significant correlation with defense mechanism.
