OBJECTIVETo observe the curative effect of Qianjin Kouchuang Jiawei Granule (QKJG) on recurrent oral ulceration [yin deficiency fire excess type (YDFET)].

METHODSTotally 120 patients who suffered from recurrent oral ulceration (YDFET) were randomly assigned to two groups, the experiment group and the control group, 60 in each group. Patients in the experiment group took QKJG, 20 g each time, twice per day, while those in the control group took Kouyanqing Granule (KG) , 20 g each time, twice per day. Fourteen days consisted of one therapeutic course, two for all. Scores for patients' symptoms and signs (ulcer area, exudation, hyperaemia, edema, the number of ulceration, burning sensation, and pain degrees) were assessed before treatment, at day 3 and 7 after treatment. Short-term efficacy was assessed by visual analogue scale (VAS). The total paralysis time and the total number of ulceration at month 12 after treatment were taken as judgment for long-term efficacy. Results Compared with before treatment in the same group, symptoms and signs were obviously improved at day 3 and 7 after treatment in the two groups (P < 0.05). Compared with the control group at day 3 after treatment, the improvement of edema, exudation, pain degree, and burning sensation was more obvious in the experiment group (P < 0.05, P < 0.01). The improvement of edema, pain degree, and burning sensation at day 7 after treatment was more obvious in the experiment group than in the control group (P < 0.05). As for short-term efficacy, the total effective rate was 86.67% (52/60 cases) in the experiment group and 83.33% (50/60 cases) in the control group, with no statistical difference between the two groups (P > 0.05). As for long-term efficacy, the total effective rate was 90.00% (54/60 cases) in the experiment group, significantly higher than that of the control group with statistical difference [81.67% (49/60 cases), P < 0.05]. At month 12 after treatment, the total number of ulceration was reduced and the paralysis time of ulcer attack prolonged in the experiment group, with statistical difference when compared with the control group (P < 0.05).

CONCLUSIONQKJG showed better long-term efficacy than that of KG in treating recurrent oral ulceration (YDFET).

The changes of interstitial cells of Cajal(ICC)distribution and connexin 43(Cx43)expression in gastric muscle layers were assayed in gastroparesis models of streptozotocin-induced diabetic rats.The results showed that gastric emptying was significantly delayed,the contraction frequency and amplitude of gastric muscle segments were greatly decreased,Cx43 gray values were significantly increased and Cx43 distributed homogeneously with ICC immunopositivity in the model rats.These changes appear to be related to the pathogenesis of diabetic gastroparesis.

OBJECTIVETo investigate whether connective tissue growth factor (CGGF) is expressed in mast cells (MCs) in lung in the development of bleomycin (BLM)-induced pulmonary fibrosis.

METHODSThirty-two male SD rats were randomly divided into 2 groups: BLM group and control group (n=16). The rats in BLM group were received single intratracheal instillation of BLM (5 mg/kg), and the rats in control group received equal volume of 0.9% normal saline(NS) to BLM. The rats in each group were sacrificed for lung tissue sampling on day 14 and day 28 after intratracheal instillation respectively. As the index of the severity of pulmonary fibrosis, the content of hydroxyproline in lungs was analyzed by chloramine T method. Mast cells and CTGF expression in lungs were examined by toluidine blue stain and immunohistochemical assay respectively.

RESULTS(1) On day 28 after intratracheal instillation of BLM, the content of hydroxyproline in lungs of rats was higher than that of control rats (P < 0.01). (2) Compared to control rats, the rats on day 14 and day 28 after instillation of BLM showed increased number of mast cells (Both P < 0.01) and up-regulated CTGF expression (Both P < 0.01). (3) No CTGF immuno-positive MCs were seen in the lungs of control rats whereas CTGF immuno-positive MCs were observed in the pathological areas in lungs of rats on day 14 and day 28 after BLM.

CONCLUSIONCTGF is expressed in MCs in lungs in the development of pulmonary fibrosis, which might be one of the mechanisms underling promoting effect of MCs on fibrosis in lung.

Objective To investigate the clinical characteristics and treatments of endometrioid carcinoma patients with preoperative diagnosis of endometrial hyperplasia.Methods From 2005 to 2010, 404 patients were diagnosed with endometrioid carcinoma after hysterectomy.Among these patients,44 of them were diagnosed atypical endometrial hyperplasia(AEH) preoperatively.Retrospectively analysis the characteristics of these patients with SPSS13.0.Results Among the 44 cases, all of them were grade G1 disease, and 39 of them received comprehensive staging surgery.14(32%)young cases preserved bilateral ovaries.9 cases(20%) were given adjuvant radiology.No recurrence was detected during the median follow up of 52 months.Compared to the premenstrual group, although no statistical difference was detected, more patients with risk factors of deep myometrium invasion(4/22 vs 1/22) and lymph-vascular space invasion(LVSI, 3/22 vs 0/22) in the postmenstrual group.Compared to the patients who diagnosed with endometrioid cancer(EC) preoperatively, there are more patients with grade G1(P=0.000), fewer patients received adjuvant chemotherapy(P=0.003) and fewer recurrence(P=0.019) in AEH group.Conclusions The endomtrioid cancer patients who diagnosed with atypical hyperplasia preoperatively have better prognosis.Hysterectomy with bilateral ovaries preserved is acceptable in young patients.Post menopause patients have more risk factors of deep myometrium invasion and LVSI.

Orobanche caerulescens is an important medicinal resource in Orobanchaceae. The present study aims to establish methods for determination of acteoside, crenatoside, and total phenylethanoid glycosides in O. caerulescens, and determine the content in 15 samples to evaluate the resource utilization of this medicinal plant. The content of acteoside and crenatoside were quantitatively determined by HPLC, while total phenylpropanoid glycosides was estimated by UV-VIS spectrophotometry. According to the results, the content of acteoside was the highest in O. caerulescens, followed by crenatoside. The contents of acteoside, crenatoside, and total phenylethanoid glycosides were between 1.15% - 15.60%, 0.83% - 4.47%, and 6.78% - 27.43%, respectively, which had significant differences. The acquisition time has great influence on the content of main components of O. caerulescens. The content of phenylethanoid glycosides is higher in the samples which were collected at the flowering stage. The two determination methods were proved to be simple, accurate and reliable, and can be used to evaluate the quality and resource utilization of O. caerulescens.

The aim of the paper is to observe the distribution of the endophytic fungi in leaves of Aquilaria sinensis by using permanent paraffin-cut section, optical microscope photography and histochemistry. Total DNA was extracted with modified CTAB method and rDNA ITS regions of plant and endophytic fungi were amplified with eukaryotic universal primers. The rDNA ITS amplicon was characterized by RFLP analysis, sequencing of rDNA ITS library and phylogenetic analyses using PAUP by maximum parsimony. Fusarium sp. A2 was used to induce the formation of resinous in A. sinensis trees. As a result, endophytic fungi mainly distributed in spongy and phloem in leaf. Endophytic fungi distributed in the phloem in agarwood-producing tree and had a relatively high abundance. Phoma sp. and Collectrotrichum sp. were the absolute advantage species in the leaf tissues of non-resinous and agarwood-producing tree, respectively. Collectrotrichum sp. was the only fungal species detected both in the two types of A. sinensis with different levels of abundance. The culture-independent molecular method can be used to identify fungal species directly and rapidly from the plant tissues. Endophytic fungal communities in non-resinous and agarwood-producing A. sinensis leaf tissues were quite different.
