The G protein-coupled receptor, GPR40, is a specific receptor for free fatty acids. Singnaling pathways are activated in islet ?-cells by fatty acids as binding to GPR40. Fatty acids regulate insulin secretion and cause ?-cell hyperplasia through GPR40. GPR40 also mediates responses to antidiabetic drugs like thiazolidinediones. GPR40 agonists and/or antagonists show potential effect in the development of new anti-diabetic drugs.

Objective To study the clinical and pathological characteristics, treatment results and prognosis of primary parotid non-Hodgkin's lymphoma (NHL). Methods All of our 21 patients received operative resection first and were histologically comfirmed as having T-cell (intermediate grade) and 20 B-cell lineage (2 high grade, 6 intermediate grade ,12 low grade) including 7 mucosa-associatied lymphoid tissue (MALT) phenotype. Ann Anbor stages were 16 stage Ⅰ E and 5 stage Ⅱ E lesions. All patients were treated by radiotherapy,of them 11 were also given 2～6 cycle chemotherapy. Results The overall 5-year survival rate was 77.0%. All 5 patients who died did so of distant involvement. Conclusions Our data show that MALT lymphoma can be present as a primary paroid NHL,although it is not included in the Working Formulation. Low-dose radiotherapy is of choice in the treatment. Patients with intermediate or high grade NHL should be given multi-modality therapy.

Objective To observe the clinical efficacy of Qufeng Qingre Weiling Decoction combined with the decreasing amount of loratadine in treatment of chronic urticaria (CU). Methods Totally 108 CU patients were randomly divided into treatment group and control group, 54 cases in each group. The treatment group was given Qufeng Qingre Weiling Decoction combined with the decreasing amount of loratadine (10 mg, 1 time per day) according to symptom controlling situation, and control group with the decreasing amount of loratadine only. Both groups were treated for 4 treatment courses (2 weeks as a treatment course). Symptom score reduce index was used to calculate the effective rate after 8 weeks of treatment. And the taking antihistamine medicine score was recorded 4, 6, 8 weeks of treatment. The follow-up visits were made to observe long-term efficacy of the cured patients 1 month, 3 months and 6 months after discontinuing the medication. Results Totally 27 cases from the treatment group were cured, with a total short-term effective rate of 96.30%;13 cases from the control group were cured, with a total short-term effective rate of 65.38%, with statistical significance (P<0.05). The taking antihistamine medicine score in treatment group (0.553 ± 0.239) was lower than that in control group (0.721 ± 0.245), namely the symptom improvement in treatment group was better than that in control group by taking less antihistamine medicine. Long-term clinical efficacy showed that the treatment group was also distinctively better than the control group. Conclusion Qufeng Qingre Weiling Decoction combined with the decreasing amount of loratadine is more effective for CU, and with better short-term and long-term clinical efficacy than the control group.

To investigate the efficacy of the formula composed of the herbal drugs to soothe the liver, regulate qi, clarify the heart and eliminate vexation plus acupuncture for general anxiety disorder. Methods: Forty cases in the treatment group were treated with acupuncture plus herbal formula and 38 cases in the control group were treated with oral Doxepin. The assessment was conducted by Self-rating Anxiety Scale (SAS) and the Treatment Emergent Symptom Scale (TESS) before, during and after treatment. Results: The total effective rate was respectively 82.50% in the treatment group and 84.21% in the control group, with a significant difference in SAS assessment (P＜0.01) between the two groups before and after the treatment.There were no significant differences in the curative and remarkable effective rate, total effective rate and SAS assessment between the two groups (P＞0.05), but the side effect was higher in the control group than in the treatment group (P＜0.01). Conclusion: Acupuncture plus herbal formula can have a precise effective effect for extensive anxiety neurosis with mild toxic side effects.

OBJECTIVE:To investigate the characteristics and general pattern of the adverse drug reactions (ADR) occurred in our hospital. METHODS:A total of 258 ADR cases collected from June 2006 to June 2008 were analyzed statistically in respect of patients' age and sex,drug variety,clinical manifestations,routes of administraiton and dosage forms etc. RESULTS:Of the total 258 ADR cases,the majority(64.34%) were induced by antimicrobial drugs; 45.74% presented with lesions of skin and its appendants,and 77.91% were induced by intravenous way. CONCLUSION:To develop and strengthen ADR monitoring and reporting should be regarded as the key to enhance medication safety.

Objective To explore the signaling pathway of AP-1 activated by epidermal growth foctor receptor(EGFR) in the rat gastric mucosal cells. Methods TGF-? stimulated freshly isolated rat gastric mucosal cells,and Western blot and EMSA detected the activation of ERK-1/2 signaling pathway. Results The exposure of the mucosal cells to 1 nmol/L TGF-? for 30 min significantly induced transcriptional activity of AP-1. This induction was associated with a concomitant activation of MEK and ERK-1/2. TGF-?-induced activation of AP-1 in gastric mucosal cells could be totally abrogated by either PD153035, a specific inhibitor of EGFR tyrosine kinase, or PD98059, a specific inhibitor of MEK. Conclusions Our findings suggest that EGFR AP-1 activates by EPK-1/2 signaling pathway in the rat gastric mucosal cells.

Objective To evaluate the potentiation of neuromuscular block produced by rocuronium during isoflurane anesthesia. Methods Sixty ASA Ⅰ -Ⅱ patients (39 male, 21 female), aged 18-56 yr, weighing 42-88 kg undergoing ENT, oral or facial plastic surgery were enrolled in this study. The patients were premedicated with atropine 0.01 mg?kg-1 . Anesthesia was induced with diazepam 0.1 mg?kg-1 , pethidine 1mg?kg-1 and droperidol 50?g?kg-1. Oro- or naso-tracheal intubation was accomplished under topical anesthesia. After intubation the patients received hydroxydione 2.5 g and fentanyl 5 ?g?kg-1 . The patients were mechanically ventilated. Anesthesia was maintained with inhalation of 50% N2O in O2 alone (groupⅠ) or combined with 0.6% isoflurane (group Ⅱ ) or 1.2% isoflurane (group Ⅲ ) . A bolus of rocuronium 0.6 mg?kg-1 was given during maintenance of anesthesia. Neuromuscular function was monitored using TOF response measured by accelerography (Biometer, Denmark). (1) Onset time (time from the end of injection to maximum depression of T1 ) , (2) the duration of T1 = 0, (3) time from the end of injection to recovery of T1 to 25% , 50% and 90% control, (4) recovery index (time from T, 25%-75%) were recorded. End-tidal isoflurane concentration was monitored.Results The onset time was significantly longer in group Ⅰ[ (1.7?0.2) min] than that in group Ⅱ[ (0.9?0.1) min] and groupⅢ[(0.8?0.1) min] ( P

To confirm the existence of heme oxygenase (HO)- carbon monoxide (CO)- cyclic guanosine monophosphate (cGMP) pathway in the cultured human trabecular meshwork cells (HT-MCs) in vitro, and to evaluate the inductive role of hemin on this pathway, HTMCs of the third to fourth generation were cultured in vitro. Reverse transcripase-polymerase chain reaction (RT-PCR) was employed for detection of HO-1 and HO-2 mRNA. Immunohistochemical staining was used to detect HO-1 and HO-2 proteins. Hemin was added into the culture solution. The HO-1 mRNA levels were quantified by RT-PCR. The relative amount of carbon monoxide released into the media was measured with the quantifying carbon monoxide hemoglobin (HbCO) by spectrophotometry. Radioimmunoassay was used to determine changes of cGMP in HTMCs. The results showed that cultured cells had the specific characteristics of HTMCs. Both HO-1 and HO-2 genes were expressed in HTMCs, as well as HO-1 and HO-2 proteins in HTMCs. Hemin induced HO-1 mRNA, HbCO and cGMP in a dose-dependent manner. In conclusion, HO-CO-cGMP pathway exists in the cultured HTMCs and can be induced by hemin. Pharmacological stimulation of HO-CO-cGMP pathway may constitute a novel therapeutic approach to rescuing glaucoma.
