Objective To study the symptomatic characteristics distribution of Chinese medicine of patients with pulmonary hypertension.Methods Symptomatic information of 52 patients with pulmonary hypertension was collected to find the symptomatic characteristics of Chinese medicine,and analyse the correlation of symptom and pulmonary hypertension with different types and degrees.Results The proportion of TCM symptom of pulmonary hypertension from high to low were syndrome of strong Qi sinking(96.2%),syndrome of blood stasis(75.0%),syndrome of deficiency of lung Qi(42.3%),syndrome of deficiency of heart Qi(30.8%),syndrome of deficiency of spleen Qi(17.3%).Syndrome of blood stasis was the most closely related to the congenital cardiopathy(CC) with pulmonary hypertension.Syndrome of deficiency of heart Qi was the most closely related to the degree of pulmonary hypertension increased pressure.The next one was syndrome of deficiency of lung Qi.Conclusion Syndrome of strong Qi sinking,syndrome of blood stasis,syndrome of deficiency of heart Qi and syndrome of deficiency of lung Qi are the main syndromes of pulmonary hypertension.Syndrome of strong Qi sinking is the most closely related to the pulmonary hypertension.

Objective To evaluate the clinical value of ultrasonography in diagnosis of benignPHand malignant thyroid nodules by binary Logistic regression model.Methods A retrospective analysis of 240 cases of thyroid nodules confirmed by pathology after operation excision was conducted.173 nodules were benign as control group,67 nodules were malignant as observation group.The ultrasonic features of thyroid nodules were collected.The factor had statistics significance by x2 test between the two groups were analyzed by binary Logistic regression.A logistic regression model was created.The ROC curve was drawn and the area under the curve was calculated.Results There were statistically significant differences among boundary,aspect ratio,shape,internal echo,calcification,acoustic halo,cervical lymphadenectasis between the control group and observation group(x2=45.392,7.590,30.039,24.168,37.406,6.893,16.078,all P<0.01).And after Logistic regression analysis,six variables that entered the regression equation were boundary(P=0.000,OR=8.437),aspect ratio(P=0.000,OR=12.816),microcalcification of the nodules(P=0.000,OR=8.893),shape(P=0.000,OR=8.791),internal echoes(P=0.001,OR=8.313)and cervical lymphadenectasis(P=0.001,OR=6.891).The accuracy of the model was 90.7%(223/246)in predicting malignant nodules in thyroid.The area under the ROC curve was(0.904±0.031).Conclusion The binary Logistic regression can be used to differentiate malignant and benign thyroid nodules,and make a more accurate judgment for the nodules in thyroid.

Effects of acupuncture on spontaneous discharges of nerve cells in ventromedial neucleus of hypothalamus (VNH) and levels of monoamine neurotransmitters in rats of obesity were observed. Results indicated that levels of tyrosine (Tyr) and dopamine f DA) were decreased, and the levels of 5 -hydroxytryptamine (5 - HT) and 5 - hydroxyindole acetic acid (5 - HIAA) increased in VNH; The frequency of spontaneous discharges of nerve cells in VNH lowered significantly in the obesity group as compared with those in the normal group; When acupuncture attained effect of weight reduction, the frequency of spontaneous discharges of nerve cells in the VMH increased obviously; the levels of Tyr, DA, tryptamine , and 5 - HT/5 - HIAA increased, and 5 - HT level decreased in VMH tissue. It is suggested that the benign regulative action of acupuncture on VNH is possibly one of the crucial factors for acupuncture in reducing body weight.

Objective To explore the central mechanism of acupuncture at Baihui (GV20) for memory impairment after stroke. Methods 32 stroke patients were randomized to receive acupuncture at Baihui (GV20) (as observation group) and acupuncture at Yanglingquan (GB34) (as control group) for 8 weeks. At the meantime, all participants received routine treatment including physical and occupational therapies. They were scanned with resting-state functional magnetic resonance imaging (fMRI) to find functional connectivity and assessed with Wechsler Memory Scale (WMS) before and after treatment. The results of WMS and functional connectivity were analyzed with Pearson's correlation. Results The memory scores and memory quotient improved significantly after treatment in the observation group (P<0.05). The functional connectivity significantly increased occurred in the left hippocampus to right inferior frontal gyrus, right middle frontal gyrus and left inferior frontal gyrus; and right hippocampus to left middle frontal gyrus, left superior frontal gyrus and left parietal lobe. Significant correlations were found between memory quotient and functional connectivity of hippocampus to frontal lobe and left parietal lobe in the observation group. There was no statistical significance in memory scores and memory quotient in the control group. The functional connectivity significantly decreased in left hippocampus to right middle occipital gyrus, and right hippocampus to right superior temporal gyrus and right posterior lobe of cerebellum. There was no statistical correlation between functional connectivity and results of WMS. Conclusion The acupuncture at Baihui can improves memory ability of stroke patients, which may associate with the increase of functional connectivity of hippocampus with frontal lobes and parietal lobes.

OBJECTIVE: To provide a clinical reference by comparing the conventional 226 Hz tympanometry with 1000 Hz tympanometry in two groups of young children with otitis media effusion evidenced by CT scan. METHOD: One hundred and seventy-seven young children (226 ears), from 1 to 60 months, with otitis media effusion were involved in this study. They were divided into six groups by age: 0-6 months group, 6-12 months group, 12-18 months group, 18-24 months group, 24-36 months group, 36-60 months group. They were tested with tympanometry of 2 probe-tones of 226 and 1 000 Hz. Type A tympanogram was defined as a normal middle ear function in 226 Hz and single-or double-peak in 1 000 Hz tympanometry. One hundred and fifty-eight normal young children (266 ears) were selected as control group. The results were analysed with Chi square test. Receiver operator characteristic (ROC) analysis was performed to evaluate the two methods. RESULT: In the young children with otitis media effusion, the detection rate of 226 Hz tympanogram in six groups was 21.1%, 35.2%, 46.9%, 42%, 62.5% and 68% respectively, while 94.7%, 98.1%, 96.9%, 91.2%, 95.8% and 88% respectively in 1 000 Hz tympanogram. In the young children with normal middle ear function, the detection rate of 226 Hz tympanogram in six groups was 95.1%, 88.6%, 85.1%, 93.3%, 88.5% and 93.5%, while 87.8%, 94.3%, 89.4%, 95.6%, 94.2% and 97.8% respectively in 1 000 Hz tympanogram. The detection rate was significantly different between 226 and 1 000 Hz tympanogram in the young children under 36-month old. CONCLUSION A single-or double-peak 1000 Hz tympanometric patterns as normal criteria was a simple way to evaluate young children s' middle ear function. 1 000 Hz tympanometry should be given priority to the children within 36-month old in detection middle ear function,the 226 and 1 000 Hz tympanometry should be done at the same time within 36-60 months old.

BACKGROUND:The measure and prediction of the shape of optic nerve head are the key issues for early diagnosis and duration prediction of glaucoma. Therefore, it is significant to research the shape variation of optic nerve head under high intraocular pressure.
OBJECTIVE:To establish three-dimensional finite element model of optic nerve head and to analyze the deformation of optic nerve head and the change in retina thickness after acute high intraocular pressure.
METHODS:Animal model of acute ocular hypertension was established by methods of anterior chamber perfusion. The tomographic images of the optic nerve head of a cat were obtained at the normal intraocular pressure and 5 320 Pa, 7 980 Pa, 10 640 Pa, 13 300 Pa, 15 960 Pa intraocular pressures using optical coherence tomography. Then, we measured the variation of retinal thickness at typical location. Basing on the tomographic images of optic nerve head of a cat at normal intraocular pressure, we obtained three-dimensional structure of retina and choroid using software MIMICS. Then three-dimensional model of optic nerve head was established by assembling the retina and choroid. The deformation of optic nerve head and the change in retinal thickness under high intraocular pressure were observed using software ABAQUS. The effectiveness of the model was verified by the experimental result.
RESULTS AND CONCLUSION:With the increase of intraocular pressure, the retinal thickness is thinner, the optic nerve head depth, width and the ratio of the depth to width are gradual y increased. It suggests that the acute high intraocular pressure causes retinal thinning, optic nerve head widening and deepening. It is feasible to establish optic nerve head modeling in vivo by using optical coherence tomography, mechanical analysis can be applied to predict the shape variation of optic nerve head, which is significant to further deduce the pathological process of glaucoma.
