Objective To observe the effects of Jieyu-Chufan capsule(JCC) on the behavior and the monoamine neurotransmitter content of cerebral in depression mouse model and explore its mechanism. Methods The ICR male mouse were randomly divided into seven groups according to their weights(the model group, the low, middle and high doses group, Baiyoujie group, the amitriptyline group, the normal control group). The low, middle and high doses group were given JCC with 1.250, 2.500, 5.000 g/kg separately by intragastric administration. Baiyoujie group was given 0.014 g/kg Baiyoujie by gavage. The amitriptyline group was given 0.050 g/kg amitriptyline by gavage. The model group and the normal control group received the same volume of distilled water intragastrically. The drugs were administrated once a day. The brepharoptosis and movement conditions of mouse were observed after 22 days. The monoamine neurotransmitter content of each group was measured after 25 days. Results Compared to the model group, the number of mouse with brepharoptosis decreased in the high dose group after 1, 2, 6 hour with reserpine injection (P<0.05 or P<0.01);the number of mouse came out from the circle increased after 4 hours with reserpine injection (P<0.05 or P<0.01);the content of NA (880.45 ± 428.81 ng/g, 875.98 ± 449.33 ng/g vs. 299.92 ± 267.08 ng/g) and DA (2 305.99 ± 530.37 ng/g, 2 169.99 ± 278.19 ng/g vs. 1 439.34 ± 357.33 ng/g) in the middle and high dose group increased (P<0.01);the content of 5-HT (781.43 ± 135.10 ng/g vs. 492.01 ± 192.80 ng/g) in the middle group increased (P<0.01). Conclusions JCC showed an antidepression influence in depression mouse model induced by reserpine. The mechanism may be related to regulating the level of monoamine neurotransmitter in the nervous centralis .

OBJECTIVETo investigate the risk factors of related disorders, which could lead to potential otitis media by observing the abnormal configuration of drum and abnormal acoustic immittance without symptoms in preschool children.
METHODSEighty-one cases (162 ears) received flexible pharyngorhinoscopy, skin prick test, CT examination of sinus, and were diagnosed as allergic rhinitis, chronic sinusitis, adenoid hypertrophy. They had no complaints of ear related symptoms, but were observed to have abnormality in ear drum by physical examined. Acoustic immittance measurement were performed, so as to estimate whether they were accompany with potential otitis media. The changes of examination and tests were analyzed before and after the treatment.
RESULTSThere were 15 cases (29 ears) with abnormal acoustic admittance among 81 cases (162 ears) who had no ear related symptoms but had different degree abnormality in ear drum. The morbidity rate of these 15 patients was 13.6% (6/44 ears) in allergic rhinitis patients, 18.2% (12/66 ears) in chronic sinusitis patients, and 21.2% (11/52 ears) in adenoid hypertrophy patients, respectively. The differences among the three diseases had statistical significance (χ² = 63.02,P < 0.05). Among 29 ears, 28 ears whose type of tympanic pressure curve were transferred from type C to type A two weeks after treatment. One ear whose type of tympanic pressure curve transferred from type B to type C four weeks after treatment. All cases had been followed up with no recurrent cases.
CONCLUSIONSSome preschool children with nasal and nasopharyngeal disorders had abnormal configuration of drum and abnormal acoustic immittance, and had potential risk for otitis media. Among the disorders, adenoid hypertrophy impact more on middle ear function. The early intervention of related diseases could prevent the developing trend of otitis media.

OBJECTIVETo explore the normal aerification of paranasal sinuses in Chinese children with magnetic resonance imaging.
METHODSTwo hundred and eighty Chinese children aged from 17 days to 14 years without any symptoms related to sinusitis were statistically analyzed in MRI features, including counting the number of paranasal sinus pneumatization and the maximum axial and sagittal area of the left maxillary.
RESULTSThe pneumatization rate of maxillary sinus was 85% in children aged from 0 to 1 years. Until 3 years the pneumatization rate of maxillary sinus was 95% and there was no significant difference in boys and girls (χ(2) = 0.741, P = 0.389). The pneumatization rate of maxillary sinus reached 100% after 4 years old. The pneumatization rate of ethmoid sinus was 100% in this study. The pneumatization rate of sphenoid sinus was 0 within 1 year old, 49% within 4 years old and 100% after 7 years old. There was no significant difference in boys and girls on the pneumatization rate of sphenoid sinus (χ(2) = 2.452, P = 0.117). The pneumatization rate of frontal sinus was 0 within 5 years old, 62% within 9 years old and 95% after 10 years old. There was no significant difference in boys and girls on the pneumatization rate of frontal sinus (χ(2) = 0.124, P = 0.724). The axial and sagittal maximum area of maxillary sinus was (689.28 ± 221.79) and (659.76 ± 263.31) mm(2) in girls and (668.13 ± 206.38) and (638.60 ± 207.67) mm(2) in boys. The differences were significant (t = -19.78, P < 0.001; t = -19.89, P < 0.001).
CONCLUSIONThe study of the development and normal aerification of paranasal sinuses of children can help radiologist make correct diagnosis of paranasal sinuses in children.

OBJECTIVETo disclose the etiological factors and to investigate the therapeutical effect on nasal disorders in 128 children with intractable cough.
METHODSOne hundred and twenty-eight children with intractable cough were consulted by ENT doctors using electronic nasopharyngoscope, for those children with nasal diseases, relevant treatment was given.
RESULTSAmong 128 children, one hundred and sixteen had nasal disorders. Upper airway cough syndrome (UACS) was diagnosed in 92 cases (71.9%), nasal disorders without UACS was diagnosed in 24 cases (18.7%), no nasal disorders were found in 12 cases (9.4%). Among children with UACS, allergic rhinitis was diagnosed in 76 cases, rhino-sinusitis in 39 cases, adenoid hypertrophy in 54 cases, and chronic rhinitis in 8 cases. However, for those children without UACS, 10 cases had chronic rhinitis and 14 cases had allergic rhinitis. Clinical symptoms, signs and the findings of electronic nasopharyngoscope were analyzed in 92 children with UACS. The results showed that regular cough occurred in 62 cases, nasal disease in 65 cases, subjective feeling of postnasal discharge in 18 cases, mouth breathing or snoring in 32 cases, purulent secretion in nasal meatus in 61 cases, retropharyngeal folliculosis in 58 cases, purulent secretion in pharynges detected from pharynx in 41 cases, and purulent or viscosity secretion were found in 91 cases by first electronic nasopharyngoscopy. After 14 days of treatment, the children with UACS (90/92) had significant higher remission rate (chi² = 32.21, P = 0.000) in cough than those who had nasal disorders but without UACS (13/24).
CONCLUSIONSThe nasal disorders, especially for UACS, were common in children with intractable cough. The therapy to nasal disorders could release the chronic cough symptoms in children with intractable cough.

Background Corneal neovascularization ( CNV ) is a complication of many ocular surface diseases.It often worsen the pathological course.Effective therapy for CNV is still researching. Objective This study was to investigate the inhibitory effect of irradiation on CNV. Methods CNV models were established in 70 right eyes of 70 clean Wistar rats by corneal alkali burning.The models were randomized into β ray 10 Gy once irradiation group( 2 eyes),β ray 7 Gy multiple irradiation group( 17 eyes),β ray 10 Gy multiple irradiation group( 17 eyes),1% cyclosporin A ( CsA ) eye drops group ( 17 eyes) and model group ( 17 eyes),and 6 matched normal rats were used as normal controls.All treatments started from the first day of the corneal alkali burning.CNV length and area were measured under the slit lamp every day.Corneal samples and homogenate were prepared 3,5,7 days after corneal alkali burning.The expressions of bcl-2,bax,vascular endothelial growth factor(VEGF) in rat corneas were detected by immunochemistry,VEGF proteins and VEGF mRNA were detected by Western blot and reverse transcription polymerase chain reaction (RT-PCR),respectively. Results Corneal ulceration was found in the βray 10 Gy once irradiation group and β ray 10 Gy multiple irradiation group.CNV length and area were much less in the β ray 7 Gy multiple irradiation group and 1% CsA eye drops group compared with the model group on the seventh day after experiment( length:q=14.40,24.20,P<0.01 ;area:q=17.80,14.00,P<0.01 ).Immunochemistry revealed that compared with the model group,expressions of bcl-2 and VEGF proteins were weaker,but the expression of bax protein was stronger in the β ray 7 Gy multiple irradiation group and 1% CsA eye drops group.RT-PCR showed that the expression of VEGF mRNA in cornea was lower in the β ray 10 Gy multiple irradiation group,β ray 7 Gy multiple irradiation group and 1% CsA eye drops group in comparison with that in model group,and the results from Western blot showed the same pattern as RT-PCR. Conclusions Low dose irradiation of 90Sr-90Y ophthalmic applicator inhibits CNV formation after alkali burn.The study provide a new understanding of the irradiation for the treatment of CNV.

OBJECTIVETo compare mini-probe endoscopic ultrasonography (MCUS) with computed tomography (CT) in preoperative T and N staging of esophageal cancer, and to find out the MCUS parameters to judge lymph node metastasis for esophageal cancer.
METHODSThirty-five patients received both MCUS and CT preoperatively, on both of which the T and N stages were determined. The accuracy, sensitivity, specificity, positive predicting value and negative predicting value were compared with the postoperative pathological results.
RESULTSThe accuracy of MCUS was 85.7% in T staging and 85.7% and 80.0% in N staging by the two different methods, which were 45.7% and 74.3%, respectively, by CT.
CONCLUSIONMCUS is better than CT in preoperative staging for esophageal cancer. The ratio of short to long axis (S/L) combined with short axis is a useful way to determine lymph node metastasis.

OBJECTIVETo evaluate the effect of snoring on facial growth in children and the changes after surgery.
METHODSObservations on facial growth were taken by X-ray 1.5 - 2 years before and after surgery on 40 children snorers aged between 2 - 5 years old, whose tonsils and (or) adenoids were completely removed. The data collected before surgery in the 2 - 3 years old snorers and in the 4 - 5 years old ones were compared with the data from healthy children at the same age respectively.
RESULTSThe comparison of data between 21 children snorers aged from 2 - 3 and 17 healthy children of the same ages showed that there was no significant difference in the diameter of pharyngeal cavity at tongue base (PAS), the diameter of nasopharyngeal cavity (UPW-PNS) and the angle between mandibular plane and frankfort horizontal plane (FH-MP) within 2 - 3 years group by statistically (P > 0.05). There is no significance in UPW-PNS and FH-MP angle within 4 - 5 years group by statistics (P > 0.05). Others results is significance in all groups (P < 0.05 or P < 0.01). There was no significant difference in all groups expect Y-axis Angle 1.5 - 2 years after surgery (P > 0.05).
CONCLUSIONSAbnormal facial growth was caused by the consistent force from the changed way of breathing due to the increasing narrowness of upper airway obstruction and the long-existing obstructive sleep. Surgery done as soon as possible is helpful to reduce the force caused by the obstruction and helpful to the normal facial growth.

BACKGROUNDMultidrug resistance to chemotherapeutic agents is an important clinical problem during the treatment of leukemia. The resistance process is multifactorial. To realize the total factors involved in multidrug resistance, we analyzed the differentially expressed proteins of K562 and K562/ADM cells and we investigated one of the up-regulated proteins (CRKL) using siRNA to determine its role in K562/ADM cells.
METHODSAltered protein expressions between K562/S (K562 ADM-sensitive cell line) and K562/ADM (K562 multidrug resistant cell line induced by adriamycin) were identified by 2D-DIGE coupled with mass spectrometry. Meanwhile, we confirmed the differential expression of CRKL and Stathmin in both K562 and K562/ADM cells by Western blot analysis. Furthermore, we used RNA interference to silence the CRKL gene expression.
RESULTSAmong the 9 differentially expressed proteins, 3 were up-regulated in K562/ADM cells, while 6 were down-regulated in the K562/ADM cells compared with its parent cell line. The expression of CRKL was up-regulated significantly in K562/ADM cells, and it can be decreased by recombinant lentivirus. Moreover, the multidrug resistance of K562/ADM cells was efficiently reversed by silence of CRKL gene expression.
CONCLUSIONSThe data provided the differentially expressed proteins in K562 and its resistant cell line and highlights the power of 2D-DIGE for the discovery of resistance markers in cancer. We found CRKL may be a new protein involved in the multidrug resistance of leukaemia cells.

OBJECTIVETo study the changes and significance of serum hydrogen sulfide (H2S) levels in children with benign infantile convulsions associated with mild gastroenteritis (BICE).
METHODSForty-two hospitalized children diagnosed with BICE were recruited to the observation group, and 46 children admitted due to acute gastroenteritis alone were recruited to the control group. Serum H2S levels were measured by a spectrophotometer.
RESULTSThe serum H2S level in the observation group was significantly lower than in the control group (28±12 μmol/L vs 45±10 μmol/L; P<0.01). The patients with a number of convulsions greater than or equal to two had significantly lower serum H2S levels than those with a number less than two (P<0.05). The number of convulsions was negatively correlated with serum H2S level in BICE patients (r=-0.485, P=0.001). When a convulsion exceeded 5 minues in duration, the duration was negatively correlated with serum H2S level (r=-0.736, P=0.004).
CONCLUSIONSThe reduction in endogenous H2S level might be one of the causes of convulsions in BICE patients. The degree of reduction in H2S level is associated with the number of convulsions and the duration of convulsion (when it exceeds 5 minues). Further investigation is needed to determine the clinical significance of these results.
