OBJECTIVETo establish the visual patch clamp whole-cell recording technique and study the properties and functional significance of muscarinic receptor-mediated currents in rat medial vestibular nucleus neurons (MVNn).
METHODSBrain slices containing the MVN were prepared from fifteen Wistar rats. By combining infrared differential interference contrast (IR-DIC) technique and CCD-Camera system with visual patch clamp whole-cell recording technique, twenty healthy neurons were located and muscarinic receptor-mediated currents in rat MVNn were observed and analyzed.
RESULTSVisual patch clamp technique can be used to make direct localization and to make sure of active neuron. In MVNn, a comparison of the current-voltage relationships before and during the application of muscarine, which revealed an increase in the slope of the I-V curve and the reversal potential for this response lay at (-88.4 +/- 4.9) mV (x +/- s), indicates that the activation of muscarinic cholinergic receptors leads to a decrease in potassium current. The test in the voltage sensitivity of the muscarine-induced response, which showed that the effect had a linear current-voltage relationship and reversed at (-86.7 +/- 3.5) mV, indicates that the potassium current blocked by muscarine corresponds to the voltage-insensitive leak potassium current.
CONCLUSIONSVisual patch clamp technique, which was considered better than blind patch clamp technique, can improve the success of sealing process. By the analysis of muscarinic receptor-mediated currents, the data provide support that muscarinic cholinergic mechanisms play a prominent role in the modulation of the excitability of MVNn and also offer a new idea for the efficacy of anticholinergic drugs.

OBJECTIVETo study the early diagnosis, treatment and Prognosis of pyriform sinus perforation.
METHODSTo study the clinical feature about 15 cases of pyriform sinus perforation, Most of the 15 cases with pyriform sinus perforation were associated with pharyngeal pain or fever. contrast x-ray studies and CT scan were used to confirm the perforation. conservative treatment in 9 cases and surgical intervention in 6 cases. and review relevant literature.
RESULTSOf all 15 cases, 9 cases with wild symptoms for conservative treatment, 6 cases with severe symptoms and complications were treated surgically. All achieved better clinical efficacy, By relevant examination, the perforation were healed within 2 - 4 weeks and none had re-perforation for 1 - 30 months follow-up.
CONCLUSIONSPyriform sinus perforation with wild symptoms and within 12 hours can be treated conservatively. Large perforation (> 2 cm) last more than 12 hours or any complications require exploration, operation repair if possible and adequate drainage. early diagnosis and effective treatment can reduce the incidence of complications and improve the survival rate of patients.

OBJECTIVETo observe the effect of volatile oil of amomum (VOA) on the expressions of mastocarcinoma-related peptide (PS2) and platelet activating factor (PAF) in helicobacter pyloriassociated gastritis (HPG) and to analyze its potential mechanism.
METHODSEighty patients with HPG were randomly assigned to two groups, 42 patients in the treated group treated with 0.5 mL VOA, thrice per day; and the 38 patients in the control group receiving Western tertiary medicinal treatment. Gastroscopic picture and helicobacter pylori (HP) infection (by quick urease and Warthin-Starry stain) of the gastro-membrane, expressions of PS2 and PAF (by immunohistochemical assay and Western blotting) as well as the contents of aminohexose and phospholipid (by Neuhaus method) in the gastric membrane of all patients were detected before treatment and 4 weeks after treatment. The clinical efficacy in the two groups was compared.
RESULTSThe total effective rate in the treated group was 88.1%, which was significantly higher than that in the control group (78.9%, P<0.05). After treatment, in the treated group, gastric membranous contents of aminohexose and phospholipid was increased, expression of PS2 elevated but that of PAF lowered, all showing significant difference as compared with those in the control group (P<0.01). In the control group, the expressions of PS2 and PAF changed insignificantly. The radical eliminating rate of HP in the treated group and the control group was insignificantly different between them (76.1% vs. 65.8%, P>0.05).
CONCLUSIONThe mechanism of VOA for anti-gastritis might be related with its action in increasing the expression of PS2 and decreasing the expression of PAF, and thus regulating the hydrophobicity of the gastric membrane.

OBJECTIVETo compare changes of hypothalamus-pituitary-adrenal axis (HPAA) in different rat models of Gan stagnation (GS), Pi deficiency (PD), Gan stagnation Pi deficiency (GSPD) syndromes, and to observe interventional effect of Chaishu Sijun Decoction (CSD, capable of soothing Gan-qi invigorating Pi) on them.
METHODSSeventy Wistar rats were divided into the normal control group (group 1), the GS group (group 2), the PD group (group 3), the GSPD group (group 4), the GS intervention group (group 5), the PD intervention group (group 6), and the GSPD intervention group (group 7) according to random digit table, 10 in each group. Rats in group 1 received no treatment. Rats in group 2 and 5 were modeled by chronic restraint method. Rats in group 3 and 6 were modeled by excess fatigue plus alimentary abstinence method. Rats in group 4 and 7 were modeled by chronic restraint, excess fatigue, and alimentary abstinence method. At the 2nd weekend of modeling, CSD at 2.86 g/kg was fed to rats in group 5, 6, and 7 by gastrogavage for 2 successive weeks. Equal volume of distilled water was given to rats in the rest 4 groups. On the 29th day, rats were killed, adrenal weight weighed, and adrenal index calculated. Levels of plasma and hypothalamus corticotropin-releasing hormone (CRH), plasma and pituitary adrenocorticotrophic hormone (ACTH), and plasma corticosterone (CORT) were determined using radioimmunity.
RESULTSCompared with group 1, adrenal index significantly decreased in group 2, 3, and 4 (P < 0.05). Of them, plasma and hypothalamus CRH, plasma CORT increased significantly in group 2 and 4 (P < 0.05). Besides, plasma and pituitary ACTH increased in group 4 (P < 0.05). Plasma and pituitary ACTH, as well as plasma CORT decreased significantly in group 3 (P < 0.05). Compared with group 2, 3, and 4, adrenal index increased significantly in group 5, 6, and 7 (P < 0.05). Compared with group 2, plasma CORT, hypothalamus CRH, and pituitary ACTH decreased significantly in group 5 (P < 0.05). Compared with group 3, plasma ACTH and CORT increased significantly in group 6 (P < 0.05). Compared with group 4, plasma CRH, ACTH, CORT, hypothalamus CRH, and pituitary ACTH decreased in group 7 (P < 0.05).
CONCLUSIONSThe function of HPA .axis was damaged to varying degrees in rats of the three models in this experiment. Hyperactivity of HPA axis existed in GS syndrome and GSPD syndrome. Impairment of feedback regulation in hypothalamus and pituitary was accompanied in GSPD syndrome. Hypofunction of HPA axis existed in PDS. CSD, capable of soothing Gan-qi invigorating'Pi, showed improvement on disarranged HPAA, but with optimal effect on GSPD syndrome. CSD had higher correlation with GSPD syndrome.

Nasal polyp (NP) is a common chronic inflammatory disease of the nasal cavity and sinuses.Although some authors have suggested that NP is related to inflammatory factors such as interleukin (IL)-1β,IL-5,IL-8,granulocyte-macrophage colony-stimulating factor (GM-CSF),tumor necrosis factor (TNF)-α,and IL-17,the mechanisms underlying the pathogenesis and progression of NP remain obscure.This study investigated the expression and distribution of IL-17 and syndecan-1 in NP,and explored the roles of these two molecules in the pathogenesis of eosinophilic chronic rhinosinusitis with nasal polyps (Eos CRSwNP) and non-Eos CRSwNP.Real-time PCR and immunohistochemistry were used to detect the expression of IL-17 and syndecan-1 in samples [NP,unciform process (UP) from patients with CRS,and middle turbinate (MT) from healthy controls undergoing pituitary tumor surgery].The results showed that the expression levels of IL-17 and syndecan-1 were upregulated in both NP and UP tissues,but both factors were higher in NP tissues than in UP tissues.There was no significant difference in IL-17 levels between the Eos CRSwNP and non-Eos CRSwNP samples,and syndecan-1 levels were increased in the non-Eos CRSwNP tissues as compared with those in Eos CRSwNP tissues.In all of the groups,there was a close correlation between the expression of IL-17 and syndecan-1 in nasal mucosa epithelial cells,glandular epithelial cells,and inflammatory cells,suggesting that IL-17 and syndecan-1 may play a role,and interact with each other,in the pathogenesis ofnon-Eos CRSwNP.

Objective To understand the prevalence and risk factors of agricultural activities related injuries among rural residents in Shandong province. Methods A retrospective investigation was conducted among agricultural profession-related workers in 20 villages with multistage cluster sampling method in Shandong province. Four times face-to-face interview were conducted by trained interviewers, including 32 students and local medical personnel under constructed questionnaires.Accidental injuries occurred in the activities or in the agricultural profession-related jobs were recorded, from May 1st 2009 to April 30st 2010. Data was input and analyzed by SPSS 13.0 statistical software. Results A total of 837 cases reported at least 1 job-related injury out of the 11 902 people who had been surveyed in one year. The crude incidence rate was 7.03% and the standardized incidence rate was 7.36%, higher in males (9.01%) than in females (4.10%), X2= 105.53, P=0.000.Children and adolescents (≤ 14 aged) had the higher incidence rate (9.50%), X2=9.70, P=0.008.People working in the area of commercial service related to agricultural products had the highest incidence rate (12.94%). In particular, those occupations that related to agricultural construction or materials appeared to have had higher incidence rates as 16.80% and 15.59% respectively, than other kinds of jobs (X2= 167.30, P=0.000). There were higher proportion of injuries occurred in the roads (28.79%), in the fields(28.08%) during labor work(38.00%) transportation(27.97%), respectively.The seasonality of agricultural injures mostly occurred between June and August, accounted for 47.43%. Major external causes related to injuries were instruments or tools (31.42%) being used,transportation (24.13%) and falls (20.19%). Wounds on limbs took the majority (56.39%). The accidental self-inflicted injury occupied 76.82%, while accidents to passive injuries occupied 11.47%,other kinds accounted for 11.71%. Most of the accidents caused mild or moderate damage, accounted for 60.22% and 30.34% respectively. 7 cases died of injuries, with the fatality rate as 0.84% and the mortality rate was 58.81 per one hundred thousand. 72 cases ended up in disability caused by injuries,with the morbidity rate as 6.05 per thousand. Answers to the major internal causes of injuries appeared to be: "did not know how to protect oneself" (29.87%) with females (45.41%) in particular,followed by "over fatigue" and "inappropriate treatment" which took the 2nd place in males. Major natural environmental factors of injuries would relate to "high air temperature and humidity but lower wind velocity"(14.93%), "unclear signs on the country road"(12.19%), "the sky was cloudy or dark"(10.87%), "slippery road caused by rain or snow" (10.51%), "kids were unintended" (10.27%) etc.Most of the wounded received treatment clinically (50.18%), with the percentile (P50) of medical cost as 182.76 RMB (Yuan). The proportion of inpatient was 27.72% and with percentile of time as P50=7.57 day and cost as P50=2840.00 RMB Yuan. The wounded had a rest of P50=5.9 days, with an indirect cost as P50=233.16 RMB Yuan. Conclusion The results of this study indicated that the incidence of agricultural profession-related injuries was high, with serious harm. Behavioral intervention and awareness of injuries should be enhanced, together with the improvement of environmental condition.
