Armillariella tabescens EJLY2098 was induced to produce ?-mannanase with konjac fine flour (Amorphopallus rivieri) as single carbon source. This induced enzyme was then purified using DEAE ion exchange chromatography and named atMAN47. Zymologic analysis showed that the molecular weight of this ?-mannanase was approximately 47 kD. The enzyme was stable when pH ranged from 5.0 to 6.5 and could be activated by Na+ and Ba2+. With an optimal temperature of 50?C. Action mode analysis of TLC revealed that the enzyme belonged to the endo-?-mannanase family. Being a meta-acid endo-?-mannanase, it was suitable to be applied to feed industry with a promising future as an enzyme preparation.

OBJECTIVETo explore the mid-term surgical results of arterial revascularization for femoro-popliteal arterial occlusive disease (lesion type C and D).
METHODSFrom January 2005 to February 2009, 191 arterial bypass had been performed on 170 patients (21 cases bilateral). There were 108 male and 62 female, age ranged from 45 to 85 years old with an average of 67 years old. The operative indication was claudication in 78 cases, rest pain in 62 cases, ischemic ulcer in 19 cases, and distal tissue necrosis in 11 cases. Arterial angiography were performed on all cases. According to TASC II document, type C lesions were seen in 127 limbs, type D lesions were seen in 64 limbs. Autogenous greater saphenous vein bypass in situ were done on 15 limbs, autogenous greater saphenous vein bypass reversed in 20 limbs, revascularization with artificial prosthesis in 128 limbs, composite grafts consisting of a prosthetic conduit with a distal venous segment in 28 limbs.
RESULTSThere were no 30-day mortality. Follow-up periods ranged 6 to 36 months with an average of (24 + or - 6) months. Seventy-three cases were lost during follow-up periods, follow-up rate was 57% (109/191). Primary patency rate was 84.4% (92/109). The patency rate was 88.2% with artificial prosthesis, 70.8% with greater saphenous vein (in situ or reversed). Secondary patency rate was 89.9%.
CONCLUSIONSArterial revascularization with artificial prosthesis is main treatment for diffused superficial femoral artery occlusive disease (TASC II type C and D lesion) with satisfied surgical results.

BACKGROUNDThe 5-hydroxytryptamine7 receptor (5-HT(7) receptor, 5-HT(7)R) plays an important role in the regulation of smooth muscle relaxation and visceral sensation and might be involved in the pathogenesis of the gastrointestinal dyskinesia, abdominal pain and visceral paresthesia in irritable bowel syndrome (IBS). The aim of this study was to investigate the role of the 5-HT(7) receptor in the pathogenesis of IBS.
METHODSA rat model of irritable bowel syndrome with diarrhea (IBS-D) was established by colonic instillation of acetic acid and restraint stress. A rat model with irritable bowel syndrome with constipation (IBS-C) was established by stomach irrigated with 0 - 4 degrees C cool water daily for 14 days. The content and distribution of 5-HT in the brain and gut were examined by immunohistochemistry and the mRNA expression of the 5-HT(7) receptor was determined by fluorescent quantitative reverse transcription polymerase chain reaction. The accumulation of cyclic adenosine monophosphate (cAMP) in all the same tissues was measured by radioimmunity.
RESULTSThe models of IBS were reliable by identification. The immunohistochemistry results showed that there were significantly more 5-HT positive cells in the IBS-D group than in the control group in the hippocampus, hypothalamus, jejunum, ileum, proximate colon and distal colon (P < 0.05), as well as more than were found in the IBS-C group in jejunum and ileum (P < 0.05). There were more 5-HT positive cells in the IBS-C group than in the control hippocampus, hypothalamus, ileum, proximate colon, and distal colon (P < 0.05). Real time-PCR results showed that the expression level of the 5-HT(7) receptor in both the IBS-C and IBS-D groups were enhanced compared with the control group in the hippocampus and hypothalamus (P < 0.05). The expression level of 5-HT(7) receptors in the IBS-C group was notably greater when compared with the controls in the ileum and colon (P < 0.05). The cAMP accumulation in the hippocampus and hypothalamus in both the IBS-C and IBS-D groups was higher than that in the control group (P < 0.01 and P < 0.05). The cAMP accumulation in the IBS-C group was higher than that in the control group in the proximal and distal colon (P < 0.05).
CONCLUSIONSThe increased 5-HT content in the brain and intestine is related to the IBS pathogenesis. The up-regulated expression of the 5-HT(7) receptor in the brain and colon might play an important role in the pathogenesis of IBS-C.

OBJECTIVETo observe the distribution features of tender points in knee of patients with knee osteoarthritis in order to provide evidences for the treatment and diagnosis.
METHODSFrom November 2011 to December 2012,86 patients with knee osteoarthritis were recruited, including 21 males and 65 females, ranging in age from 45 to 85 years old, with an average of (59.98 +/- 8.23) years old. The course of disease ranged from 3 months to 15 years. The tender points and its distributions were determined by finger press carefully on their knees. Data of studying was analyzed by frequency statistics and Hierachical cluster analysis.
RESULTSThe distribution of tender points in the knee osteoarthritis was mainly in the interior region and anterior area such as in apex of patella, adductor tubercle and et al. According to the results of hierachical cluster analysis, the tender points could be divided into two categories the first cluster was in the interior region of knee, the second cluster was in the lateral region.
CONCLUSIONThe findings demonstrated that cluster analysis statistical method can be used for classification of the distribution of tender points. The distribution features of tender points in knee osteoarthritis are related to the anatomic site in knee.
