Objective To compare the differences of cognitive dysfunction and hippocampal atrophy among patients with temporal lobe epilepsy (TLE) and healthy controls and probe into the relativity of cognitive dysfunction with hippocampal atrophy after temporal lobe epilepsy. Methods Forty-nine TLE cases and 20 healthy individuals were randomly selected. The WAMS-R and WAIS-R scales were adopted to assess the memory and intelligence of all the subjects. Hippocampal volumes were measured by semiautomatic measurement on the head magnetic resonance imaging (MRI). The degree of hippocampal atrophy (DHA) and asymmetry index (AsI) were caculated by adjusting hippocampal volumes and ratio of difference of two lateral hippocampal volumes. Results Compared with the healthy controls, not only did the TLE patients exhibit more memory deficits (83.2±21.0,t=-3.365 ,P=0.001 ), but also more fullscale intelligence (91.0±12.3, t=- 4.291, P=0.000). The bilateral hippocampi of all TLE patients significantly decreased in volume ( P=0.000 ) and increased in AsI ( t=3.975, P=0.000 ). The MQ of TLE patients was significantly negatively related to the duration of the illness ( r=-0.339, P=0.017 ). The bilateral DHA and the hippocampal AsI were negatively related to Z scores (left: r=-0.297, P= 0.038, right: r=-0.305, P=0.033, AsI: r=-0.441, P=0.002), repectively. Conclusions The more the DHA and asymmetry of bilateral hippocampi, the worse the cognitive dysfunction. The quantitative measurements of hippocampal volume could be used as a clinically effective factor for evaluating the decrease of the intelligence of TLE patients.

Objective To investigate the current situation of maternal self- efficacy of breastfeeding and explore its influencing factors in Zhengzhou. Methods Using the general condition questionnaires, breast feeding self-efficacy scale, perceived social support scale and Edinburgh postnatal depression scale to assess the situation of 180 puerperas by the convenience sampling in one obstetric hospital of Zhengzhou. Results The total score of maternal breast feeding self-efficacy was(114.04 ± 21.57)points.The frequency of delivery, the way of delivery and feeding ways, the average income of family were effected with breastfeeding self-efficacy. The total score of social support was(68.87 ± 10.43) points, the total score of puerperas depression was(7.61 ± 4.25) points.The social support score had positive correlation with breastfeeding self-efficacy(r=0.423, P<0.01). Puerperas depression had negative correlation with breastfeeding self- efficacy(r=- 0.342, P<0.01). Conclusions The maternal breastfeeding level in Zhengzhou was at a lower level. The level of maternal breastfeeding self-efficacy scale was impacted by maternal social support degree, the degree of depression. Measures should be taken to enhance maternal social support degree, reduce the degree of depression, in order to improve the level of maternal breastfeeding self-efficacy.

Objective To investigate the possible effects of COL8A1 on the proliferation, invasion and drug sensitivity of murine hepatocarcinoma cell line Hca-F, we used an RNA interference (RNAi) approach to silence COL8A1 expression. Methods The expression levels of COL8A1 in HcaF/siRNA cells were assessed by RT-PCR and Western blot. The inhibitory effect of RNAi on Hca-F cell invasion in vitro was demonstrated by ECM invasion assay. The in vitro proliferative ability and drug sensitivity of COL8A1-deficient cells were determined by MTT assay. Results The expression of COL8A1 was significantly reduced in COL8A1/siRNA cells after 30h transfection, compared with both the RNAi control and the Hca-F cells. The reduced COL8A1 expression also attenuated the proliferative, invasive ability, as well as increased drug sensitivity of Hca-F/siRNA cells. Conclusion Our current results indicate that the expression of COL8A1 functionally mediates tumor cell proliferation, invasion, and drug sensitivity, and is a potential target for therapeutic anti-cancer drugs.

OBJECTIVE:
To evaluate the protective effects of oral administration of D-methionine tablets on noise-induced hearing impairment.
METHOD:
Two hundred and three volunteers were recruited and randomly divided into two groups: experimental group (n= 113) and control group (n=90). The subjects received oral administration of D-methionine tablets in the experimental group and placebo in the control group before noise exposure. Routine audiometric evaluation and ABR testing were performed and recorded before and after noise exposure. The statistical analysis was carried out with SPSS 11.0.
RESULT:
There were no differences in auditory threshold and I-V interpeak latency pre-noise exposure (P>0.05), however, there were statistically significant differences between two groups 1 d, 7 d after noise exposure (P<0.01 and P<0.05). In-respective-group, there were statistically significant differences between before and 1 d after noise exposure (P<0.05 and P<0.01), however, no difference was noted between before and 7 d after noise exposure in the experimental group (P>0.05).
CONCLUSION
The protective effects of D-methionine tablets were prominent on the noise-induced hearing impairment. Further studies regarding the optimal time of D-methionine administration will be recommended in the future.

OBJECTIVE:
To study clinical characteristics, diagnosis, pathological types and therapy methods of nonsquamous cell neoplasm in subglottis, in order to improve comprehension of this rare disease.
METHOD:
To analysis 3 patients' clinical data with noosquamous cell neoplasm in subglottis by reviewing related literature, and to generalize the symptoms, differentiation and treatment experience of nonsquamous cell neoplasm in subglottis.
RESULT:
Among the 3 patients, one's main complain was hoarseness and the other two's main symptom was inspiratory dyspnea. As diagnosis was definite and acute obstruction of airway was relieved, the neoplasms were removed totally. Two patients were undergone operation through oral cavity by using suspended laryngoscope, and one patient was done surgery by neck approach. Paraffin wax result showed that one patient suffered epithelial-myoepithelial carcinoma, who received radiotherapy after surgery. There is no recurrence in all patients by following up more than 1 year.
CONCLUSION
The occurrence of nonsquamous cell neoplasm in subglottis is relatively low, and the subglottis should be inspected carefully to avoid missed diagnosis. Operation is the preferred method to treat this kind of disease. To choose a suitable operational manner according to size, location of the neoplasm is crucial.
