Objective To investigate the expressions of cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) in colonic mucosa of patients with ulcerative colitis (UC)and to analyze the relationship between them. Methods The specimens of colonic mucosa from 32 UC patients were graded according to endoscopic and histological grading standards, and specimens of colonic mucosa from 26 healthy controls were also collected. The expressions of COX-2 and 5-LOX mRNA and protein in colonic mucosa were determined using real-time fluorescent quantitative reverse transcription polymerase chain reaction(RT-PCR) and immunohistochemistry. The correlation between COX-2 and 5-LOX was analyzed. Results For UC patients,10 were class 1, 19 class 2 and 3 class 3 according to endoscopic grading, whereas 19 were class Ⅰ , 9 class Ⅱ and 4 class Ⅲ according to histological grading. The expressions of COX-2 and 5-LOX mRNA in active UC patients were 81. 25% and 53.13%, respectively, and were 11.54% and 19. 23% in healthy controls, respectively, with significant differences between the two groups (all P values＜0.01). The positive expressions of COX2 and 5-LOX increased in accordance with increasing of endoscopic grading and histological grading.The levels of COX-2 and 5-LOX were 20. 08±1.17 and 37.83 ±1.48 in colonic mucosa tissues of UC patients, respectively, and 48.42 ± 1.69 and 11.28 ± 1.62 in healthy controls, respectively. There was significant difference between the two groups (all P values＜0.05). A good positive correlation was found between COX-2 and 5-LOX. Conclusions The expressions of COX-2 is closely related to 5-LOX in UC patients. Both may play a pivotal role in inflammation of UC.

Objective To evaluate the clinical effectiveness in screening asymptomatic diabetic peripheral neuropathy(ADPN) by the Michigan neuropathy screening instrument (MNSI) and the Toronto clinical scoring system(TCSS).Methods MNSI,TCSS and neural electrophysiological test (NET) were conducted in 232 neurologically asymptomatic type 2 diabetes patients.By using the results of NET as the golden criteria for diagnosis of ADPN,we evaluated the effectiveness of the two different scoring system by the receiver operator characteristic curve.The sensitivity,specificity,positive and negative predictive values,accuracy,Youden indexes and kappa values on different diagnostic cut-off points of MNSI and TCSS were analyzed.The correlation between the two different scoring system and the risk factors of diabetic peripheral neuropathy (DPN) were also analyzed.Results The area under the ROC curve of MNSI and TCSS were 0.792,0.704,respectively.The sensitivity,specificity,accuracy,Youden indexes and kappa values of MNSI over 2 and TCSS over 2 were 66.2％ vs 73.3％,90.4％ vs 63.7％,78.3％ vs 68.5％,0.566 vs 0.370,and 0.588 vs 0.345,respectively.MNSI was better than TCSS in the effectiveness of diagnosing ADPN and consistence with the result of NET.Moreover,MNSI was associated with the most related risk factors of DPN including age,glycosylated hemoglobin (HbA1c),HbA1c × disease duration,islet function and HDL-C.Conclusions MNSI could be used as a relatively simple and reliable method for clinical and epidemiological screening and assessment of ADPN.

To observe the clinical effect of Yisui decoction plus western medicine in treating multiple system atrophy patients, totally 65 patients from China-Japan Friendship hospital during 2008-2012 with complete clinical data and received consecutive traditional Chinese medicine and western medicine treatment for more than 3 months were observed changes of traditional Chinese medicine symptom score, part 1 of unified multiple system atrophy rating scale, orthostatic hypotension before treatment and after 3 months treatment. After 3 months treatment, total effective rate of traditional Chinese medicine symptom was 70.8%. Compared with before treatment, score of part 1 of unified multiple system atrophy rating scale was obviously reduced after 3 month treatment (P < 0.001). Ex- cept swallow function without significant improvement, the remaining projects of unified multiple system atrophy rating scale were im- proved obviously (P < 0.05), of which the most obvious differences were orthostatic symptoms, falls and intestinal function (P < 0.001). Orthostatic hypotension after 1 month treatment and 3 month treatment was obviously better than before treatment (P < 0.001). There was no significant difference in orthostatic hypotension between 1 month treatment and 3 month treatment. The research results show that Yisui decoction plus western medicine has a certain effect on improving clinical symptoms of multiple system atrophy patients, especially has a significant effect on orthostatic hypotension, and can maintain a stable clinical effect in a certain period of time.

Methods: 104 CP children were treated mainly with physiotherapy and acupuncture, together with occupational therapy, sensory integration and electrical stimulation. Gross Motor Function Measure (GMFM) was used to assess the effects of treatment. Results: After treatment for 3.29±0.80 months, the majority of CP children improved their IQ and limb symptoms, with decreased abnormal posture, increased muscle strength and improved motor developmental function. GMFM88 and GMFM66 scores had significantly increased after treatment. Conclusions: Combined treatment with Chinese and Western Medicine has confirmed effects on CP children.

OBJECTIVETo observe the effects of Danlou Tablet (DT) on inflammatory reaction, and expressions of lipoprotein-associated phospholipase A2 (LP-PLA2), secretory phospholipase A2 (sPLA2), and to analyze potential mechanisms.

METHODSForty male Wistar rats were randomly and equally divided into five groups, i.e., the normal control group, the model group, the Western medicine (WM) group, the low dose DT group, the high dose DT group, 8 in each group. Rats in the normal control group were fed with basic forage for 12 successive weeks, while AS rat model was established in rats of the other four groups by feeding high fat and sugar forage plus intraperitoneal injection of vitamin D₃. Normal saline, atorvastatin calcium suspension (at the daily dose of 1.8 mg/kg), low dose DT suspension (at the daily dose of 450 mg/kg), and high dose DT suspension (at the daily dose of 900 mg/kg) were administered to rats in the model group, the WM group, the low dose DT group, the high dose DT group respectively by gastragavage for 8 successive weeks. The general condition of all rats was observed. Rats were sacrificed after gastric administration and their serum collected. Serum levels of lipids (TC, TG, HDL-C, LDL-C) and inflammatory factors [IL-6, TNF-α, monocyte chemoattractant protein 1 (MCP-1), oxidized low-density lipoprotein (ox-LDL), lipoprotein-associated phospholipase A2 (LP-PLA2), secretory phospholipase A2 (sPLA2)] were detected. Pathological changes of thoracic aorta were observed by HE staining. Protein and gene expressions of LP-PLA2 and sPLA2 in thoracic aorta were measured by Western blot and real-time fluorescent quantitative PCR respectively.

RESULTSCompared with the normal control group, rats in the model group were in low spirits and responded poorly. Typical atherosclerotic plaque could be seen in thoracic aorta of rats in the model group. Serum levels of TC, TG, LDL-C, IL-6, TNF-α, MCP-1, ox-LDL, LP-PLA2, and sPLA2 significantly increased (P < 0.05); protein and gene expressions of LP-PLA2 and sPLA2 in rat thoracic aorta increased (P < 0.05) in the model group. After 8 weeks of intervention, rats in 3 medication groups appeared active, and HE staining showed subsidence of plaque in rat thoracic aorta. Compared with the model group, serum levels of TC, TG, LDL-C, IL-6, TNF-α, MCP-1, ox-LDL, and LP-PLA2 decreased in 3 medication groups (P < 0.01, P < 0.05); serum sPLA2 level decreased, protein and mRNA expressions of LP-PLA2 and sPLA2 in rat thoracic aorta decreased in the WM group (P < 0.01, P < 0.05); protein and mRNA expressions of LP-PLA2 in rat thoracic aorta significantly decreased in the low dose DT group (P < 0.01, P < 0.05), and those of LP-PLA2 and sPLA2 decreased in the high dose DT group (P < 0.01, P < 0.05).

CONCLUSIONDT could fight against inflammatory reaction and AS possibly through inhibiting LP-PLA2 expression and reducing ox-LDL production.

This paper aims to establish a method for the determination of sulfur dioxide in sulfur fumigation Chinese herbs. Sample powder and hydrochloric acid solution were isolated by paraffin layer in order to avoid early reactions, with the generation of sulfur dioxide, headspace with airtight needle was used to transfer sulfur dioxide into gas chromatograph, and detected with thermal conductivity detector. The analytical performance was demonstrated by the analysis of 12 herbs, spiked at four concentration levels. In general, the recoveries ranging from 70% to 110%, with relative standard deviations (RSDs) within 15%, were obtained. The limit of detection (LOD) was below 10 mg x kg(-1). Standard addition can be used for low recovery samples. The method is simple, less time-consuming, specific and sensitive. Methods comparison revealed that gas chromatography is better than traditional titration in terms of method operability, accuracy and specificity, showing good application value.
