Objective To explore the correlations of expressions of gastric mucosa water channel aquaporin AQP3 and AQP4 and different gastritis types. Methods The gastric mucosa was mounted under gastroscope. The types of gastric mucosa pathology and activity were tested by the common pathohistology. The expressions of AQP3 and AQP4 were determined by immunohistology. Results The expressions of AQP3 and AQP4 of chronic superficial gastritis were significantly higher than those in the non-gastritis group and chronic atrophic gastritis group (P < 0.01), especially in the activity period of chronic superficial gastritis. The expressions of AQP3 and AQP4 of chronic atrophic gastritis group were reduced when compared to those in the non-gastritis group, in spite of no statistical differences between them. While compared to the non-gastritis group , the expression of AQP3 of chronic atrophic gastritis group during the active stage was remarkably decreased (P < 0.05). Conclusion The expressions of AQP3 and AQP4 of gastric mucosa in chronic gastritis in various pathological types are different. AQP3 and AQP4 may be the targeted point , which could be used for the differential diagnosis and treatment of chronic gastritis of different pathological types.

Objectives To investigate the clinical features of Guillain-Barré syndrome (GBS) in children from Shen-zhen. Methods The clinical manifestations, results of electrophysiological tests and prognosis of 28 GBS patients from July 2002 to July 2012 were retrospectively analysed. Results Of 28 children, 16(57.1%) had preceding acute upper respiratory infection for 3-14 days but no patient had acute gastroenteritis. One had received HBV vaccination in 2 weeks before the onset of GBS. The peak season for GBS is spring. According to the clinical presentations and the neurophysiological results 17 patients had demyelinating neuropathy, 5 acute motor axonal neuropathy, 2 acute motor sensory axonal neuropathy, 3 Miller-fisher syndrome, and 1 polyneuritis cranialis. 14 (50.0%) patients suffered from pain in limbs which is the most nota-ble symptom in the early stage. Intravenous immune globulin (IVIG) and steroids were given during the acute phases in the majority of the patients, and assisted ventilation was performed in 2 patients due to respiratory muscle paralysis. No diffe-rence was found in Hughes scores, average hospitalization durations, and the prognosis between patients with GBS variants patients and patients with classic GBS. Conclusions Children with GBS in Shenzhen area have different clinical features.

Objective To identify the differentially expressed microRNAs in the early transformed cells,the late transformed cells and their parental BEP2D cells.Methods The differentially expressed microRNAs in the above cells were identified by microRNAs microarray assay.Results There were 38differentially expressed microRNAs in R15H20 cells versus BEP2D cells,with 18 upregulated and 20downregulated microRNAs.R15H20 and RHT35 cells shared 25 differentially expressed microRNAs compared with BEP2D cells,with 15 down-regulated and 10 up-regulated microRNAs.There were 87differentially expressed microRNAs in RHT35 cells versus BEP2D cells,with 47 upregulated and 40 downregulated microRNAs.There were 38 differentially expressed microRNAs in RHT35 cells versus R15H20 cells with 20 upregulated and 18 downregulated microRNAs.Conclusions microRNAs are differentially expressed in the different stages of carcinogenesis of BEP2D cells induced by α particles,which suggests that microRNAs may play an important role in α particle-induced malignant transformation of BEP2D cells.

In order to provide anatomical basis for transoral approach (TOA) in dealing with the ventro lesions of craniocervical junction, and the design and application of artificial atlanto-odontoid joint, microsurgical dissecting was performed on 8 fresh craniocervical specimens layer by layer through transoropharyngeal approach. The stratification of posterior pharyngeal wall, course of vertebral artery, adjacent relationship of atlas and axis and correlative anatomical parameters of replacement of artificial atlanto-odontoid joint were observed. Besides, 32 sets of atlanto-axial joint in adults' fresh bony specimens were measured with a digital caliper and a goniometer, including the width of bony window of anterior arch of atlas, the width of bony window of axis vertebra, the distance between superior and inferior two atlas screw inserting points, the distance between two axis screw inserting points etc. It was found that the width of atlas and axis which could be exposed were 40.2+/-3.5 mm and 39.3+/-3.7 mm respectively. The width and height of posterior pharyngeal wall which could be exposed were 40.1+/-5.2 mm and 50.2+/-4.6 mm respectively. The distance between superior and inferior two atlas screw inserting points was 28.0+/-2.9 mm and 24.0+/-3.5 mm respectively, and the distance of bilateral axis screw inserting points was 18.0+/-1.2 mm. The operative exposure position through TOA ranged from inferior part of the clivus to the superior part of the C3 vertebral body. Posterior pharyngeal wall consisted of 5 layers and two interspaces: mucosa, submucosa, superficial muscular layer, anterior fascia of vertebrae, anterior muscular layer of vertebrae and posterior interspace of pharynx, anterior interspace of vertebrae. This study revealed that it had the advantages of short operative distance, good exposure and sufficient decompression in dealing with the ventro lesions from the upper cervical to the lower clivus through the TOA. The replacement of artificial atlanto-odontoid joint is suitable and feasible. The design of artificial atlanto-odontoid joint should be based on the above data.

OBJECTIVETo explore the synergistic antidepressant effect of quercetin and hyperforin (HF, extracted from Hypericum perforatum).

METHODSMale ICR mice were divided into nine groups:blank control, positive control (Paroxetine, 10 mg/kg), quercetin groups (A: 5 mg/kg, B: 10 mg/kg, C: 20 mg/kg), Hypericum perforatum extract (HF 10 mg/kg),combination groups (A: quercetin 2.5 mg/kg + HF 5 mg/kg,B:quercetin 5 mg/kg + HF 5 mg/kg,C: quercetin 10 mg/kg + HF 5 mg/kg). All drugs were administered intragastrically. Reserpine reversal tests were used to compare the reversal effects of drugs on body temperature decline, eyelid ptosis and akinesia. Tail suspension test was used to compare immobility time in each group.

RESULTSCombination group B showed no significant difference (P>0.05) compared with combination group C in reserpine reversal tests and tail suspension test. However, its body temperature reversal effect was significantly higher (P<0.01) than that of quercetin group B, and its effect in shortening immobility time was stronger than that of HF 10 mg/kg group (P<0.05) and quercetin group B (P<0.01).

CONCLUSIONThe combination of quercetin and Hypericum perforatum extract in certain ratio has significant synergistic antidepressant effect in ICR mice.
