The phytase was extracted from solid state leavening of Trichoderma Viride LH374.The crude product was purified by(NH_4)_2SO_4 precipitation,gel filtration and ion exchange chromatography.The purified phyatse was 13.3 times of the raw products,and the extraction ration was 27.1%.The study on the enzymology of phyatse showed that the optimal temperature and pH were 55℃ and 6.0,respectively.The Km value of the phytase was 0.15mmol/L.

Objective To observe the anticoagulant effect of low molecular weight heparin on induced hemodialysis in patients with acute renal failure.Method One hundred and eight patients with acute renal failure treated with induced hemodialysis were randomly divided into low molecular weight heparin(LMWH)group and unfractionated heparin(UFH)group.A bolus disc of UFH was given at first and then maintained by continuous infusion in UFH group,whereas a single bolus dose of LMWH with 2000AFXa IU to 4000AFXa IU in LMWH group.Results Anticoagulant effect between LMWH and UFH did not show significant discrepancy during induced hemodialysis.The bleeding from internal jugular vein catheter increased in the UFH group much more than that in the UFH group was significantly higher than that in the LMWH group.Anti-FXa blood levels were significantly higher in LMWH group than in UFH group.Conclusions LMWH has minor influence on aPTT and TT,while its anticoagulation effect approximates to that of UFH.LMWH represents a realistic alternative agent UFH in acute renal failure induced hemodialysis.

Objective To determine the levels of plasma histamine and oxidative status in patients with dermatographism before and after the treatment with anti-histamine drugs. Methods Totally, 85 patients with dermatographism were randomly divided into two groups to receive oral desloratadine and cetirizine respectively for 4 weeks. Enzyme linked immunosorbent assay (ELISA) was performed to detect the plasma level of histamine, superoxide dismutases (SOD), glutathion peroxidase (GSH-PX) and malondialdehyde (MDA) in all the patients before and after the treatment and in 15 normal human controls. The efficacy of desloratadine and cetirizine for dermatographism was estimated. Results The response rate was 83.72% and 78.57% in patients treated with desloratadine and those with cetirizine, respectively (x2 = 0.369, P> 0.05). The untreated patients with dermatographism showed an elevation in the plasma level of histamine (3.87 ± 1.21 ng/ml vs. 1.76 ± 0.56 ng/ml, P< 0.05) and MDA (3.86 ± 1.03 nmol/ml vs. 2.19 ± 0.82 nmol/ml, P< 0.05), but a decline in the activity of SOD (86.29 ± 19.9 U/ml vs. 112.12 ± 27.88 U/ml, P< 0.05) and GSH-PX (74.52 ± 47.67 vs.915.06 ± 115.96, P< 0.05) compared with the normal human controls. The treatment with antihistamine induced a reduction in the plasma level of histamine (1.61 ± 0.47 ng/ml vs. 3.87 ± 1.21 ng/ml, P< 0.05) and MDA (2.65 ± 0.77 nmol/ml vs. 3.86 ± 1.03 nmol/ml, P< 0.05), but an increment in the activity of GSH-PX (921.46 ± 157.37 vs.74.52 ± 47.67, P < 0.05) with no changes of SOD in patients with dermatographism. Conclusions In patients with dermatographism, plasma histamine is increased and there is an imbalance of oxidation-antioxidation.Desloratadine and cetirizine are effective for the treatment of dermatographism.

OBJECTIVETo explore effective therapeutic methods for sensorineural hearing loss (SNHL).

METHODSThirty-four cases of mild and moderate SNHL who were definitely diagnosed with pure tone test and by otologists, including 24 cases of insufficiency of the liver and kidney, 10 cases of excess of liver-fire. They were treated with acupuncture at main points, Ermen (TE 21) or Tinggong (SI 19) or Tinghui (GB 2), and Yifeng (TE 17), Shenting (GV 24), Baihui (GB 20), Houding (GV19), Touwei (ST 9), Conger 1-3, Congnao 1-2; and adjuvant acupoints: Huangshu (KI 16), Qihai (CV 6), Guanyuan (CV 4), Taixi (KI 3) were added for insufficiency of the liver and kidney; Zhongwan (CV 12), Tianshu (ST 25), Yanglingquan (GB 34) and Taichong (LR 3) were added for excess of liver-fire. Sequential multipoint pulse stimulation was adopted, twice each week, for 20 consecutive weeks (40 sessions) and then pure tone test was carried out repeatedly.

RESULTSOf 34 cases (58 affected ears), 13 cases were cured and 21 improved, and the various linguistic frequency hearing threshold pure hearing values before and after treatment increased significantly (P < 0.05).

CONCLUSIONAcupuncture and continuous multipoint pulse stimulation has definite therapeutic effect on linguistic frequency hearing loss in the patient of SNHL.

OBJECTIVETo compare the clinical effects between hip anterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery and posterior K-L approach combined with quadratus femoris bone flap transplantation for the treatment of femoral neck fracture of Garden III-IV in young and middle-aged patients.

METHODSFrom January 2004 to January 2011,46 patients with femoral neck fractures were treated by two kinds of operation. Among them, 20 cases were treated with anterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery, included 12 males and 8 females with an average age of (32.1 ± 7.3) years old, involved 12 cases of Garden III and 8 cases of Garden IV. The other 26 cases were treated with posterior K-L approach combined with quadratus femoris bone flap transplantation, included 20 males and 6 females with an average age of (37.8 ± 6.9) years old, involved 16 cases of Garden III and 10 cases of Garden IV. The index of hospitalization (hospitalization time, total cost, operative time, intraoperative blood loss, postoperative complications), the quality index of operation (fracture reduction, position of internal fixation, fracture healing time, nonunion and femoral head necrosis) of two groups were observed and compared. Hip joint function were evaluated by Harris score.

RESULTSAll patients were followed up from 28 to 41 months with an average of 36 months. The intraoperative blood loss of group S-P (92.3 ± 10.4) ml was less than that of group K-L (132.4 ± 11.2) ml, there was significant difference between two groups (P < 0.05). The operation time of group S-P (81.4 ± 9.2) min was more than that of group K-L (67.1 ± 4.5) min, the difference was statistically significant (P < 0.05). One case in group S-P and 9 cases in group K-L appeared postoperative complications, there was significant difference between two groups (P < 0.05). The fracture healing time of S-P group (83.5 ± 7.3) d was shorter than that of group K-L (103.2 ± 12.6) d, there was significant difference between two groups (P < 0.05). At 30 months after operation, there were significant difference in Harris scoring between two groups (P < 0.05).

CONCLUSIONAnterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery for treatment of femoral neck fracture of Garden III-IV of young and middle-aged patients, it has characteristics in clear anatomic and easy to operate. As compared with K-L approach, S-P approach can better reserve residual blood supply of femoral neck. While combining with the iliac bone flap transplantation with deep circumflex iliac artery, it could better reconstruct the blood supply of femoral neck to promote fracture healing.

To analyse the relationship between tumor necrosis factor (TNF)-α and interleukin-6 with hyperuricemia in ethnic Uygur,Kazak,and Han in Xinjiang province.1 200 cases of Uygur,Han,and Kazak populations were randomly enrolled.Serum uric acid,triglyceride,total cholesterol,high density lipoprotein-cholesterol,low density lipoprotein-cholesterol,fasting plasma glucose,body weigh and height,waist circumference,and hip circumference were measured.Waist-to-hip ratio and body mass index were calculated,and TNF-α,interleukin-6 were determined.The differences between uric acid and inflammatory factors were statistically significant; The differences in TNF-α was statistically significant between high uric acid group and control group in Uygur and Han,and the differences in interleukin-6 was statistically significant between high uric acid group and control group in Uygur,Kazak,and Han(P＜0.01).TNF-α and interleukin-6 were positively correlated with serum uric acid in Uygur,but in Kazak only interleukin-6 was negatively correlated with serum uric acid,in Han only interleukin-6 was positively correlated with serum uric acid(P ＜ 0.01).Hyperuricemia was associated with inflammatory factors,TNF-α,interleukin-6,but there were ethnic differences among Uygur,Kazak,and Han,thus it may provide people of new ideas for prevention and treatment of hyperuricemia and other related metabolic disorders.

The heterogeneity of high-density lipoprotein-cholesterol (HDL-C) in hyperuricemia was analyzed in Uygur,Han,and Kazak ethnic groups in Xinjiang.A total of 2 396 subjects were surveyed.The HDL-C levels were significantly decreased in hyperuricemia group compared with control group in Han and Uygur,while the reverse occurred in Kazak.The serum uric acid (SUA) level in Kazak was the lowest.The SUA was negatively correlated with HDL C in Kazak (P ＜ 0.05).HDL-C was a recognized protective factor for cardiovascular disease.With the lowered SUA level in the Kazak group,HDL-C level was increased.When SUA level was higher than a certain level (such as the SUA-4),there existed a negative impact on cardiovascular disease
