Objective To analyze hematosis of modified homemade Buxue decoction discriminate on patients with hemorrhagic anaemia after unilateral total hip arthroplasty and prognosis.Methods88 patients with hemorrhagic anaemia who underwent unilateral total hip arthroplasty in our hospital from February 2015 to Janurary 2017 were selected, they were randomly divided into the observation group and the control group, 44 cases in each group.The control group received pure western medicine after unilateral total hip arthroplasty, the observation group added modified homemade Buxue decoction discriminate on the basis of the control group.Clinical therapeutic effect on anemia, hematosis indexes including hemoglobin (HB), red blood cell (RBC), erythrocrit (HCT) in the two groups were compared, occurrence of complications during postoperative treatment, hip scores were used to compared prognostic differences in the two groups.ResultsTotal effective rate of the observation group 95.45% was significantly higher than the control group (81.82%) (P<0.05);there was no significant difference in Hb, RBC and HCT level before the treatment in the two groups, Hb (130.23±13.09)g/L, RBC (4.16±0.71)×1012/L and HCT (0.42±0.03) in the observation group after the treatment were significantly higher than the control group (P<0.05);complication rate in the observation group 9.10% was significantly lower than the control group (25.00%) (P<0.05);there was no significant difference in hip joint function scores before the treatment in the two groups, hip joint function score in the observation group after the treatment (79.73±5.42)scores was significantly higher than the control group (P<0.01).ConclusionTreatment effect of modified homemade Buxue decoction discriminate on hemorrhagic anaemia after unilateral total hip arthroplasty is significant, can promote recovery of hematosis, hip joint and motor function effectively.

BACKGROUND: Recently, with the increasing popularity of dental implant and orthognathic surgery, more and more people pay attention to the structure of mandibular canal and adjacent tissues. However, there are few reports addressing specimen measurements at home and abroad. OBJECTIVE: To measure the anatomical data of mandibular canal and adjacent tissue of mandible specimen to provide reliable reference data and anatomical evidence for alveolus surgery, tooth implantation, and orthognathic surgery. DESIGN, TIME AND SETTING: A controlled observation was performed at the Laboratory of Anatomy, Jilin Medical College between March 2007 and September 2007. MATERIALS: Twenty complete mandible specimens. METHODS: Sixteen adult, ex vivo mandibles with complete dentition and 4 edentulous mandibles were measured in every dental position of sagittal profile and posterior mental foramen in terms of molar, alveolar crest, and mandibular canal. Data were statistically analyzed. MAIN OUTCOME MEASURES: Mental foramen location, horizontal distance from anterior border of mental foramen to anterior border of mental canal, mandibular foramen location, distances from mandibular canal to molar root tip, lingual bone plate of mandible, inferior border of mandible, mandibular buccal bone plate, and alveolar ridge crest. RESULTS: Mandibular canal, located in the inferior region of the mandible body, ran towards the lingual side and was close to the inferior border of mandible and most close to the mandibular molar root tip. It turned towards posterolateral and buccal side in front of mental foramen and then passed through mental foramen. The distance of mandibular canal between edentulous mandible and alveolar ridge crest was obviously shortened. CONCLUSION: Multi-section observation and measurement of ex vivo mandible specimens provide precise, reliable evidence for preoperative design of orthognathic surgery, facilitate surgeons to better formulate surgical proposals, and prevent some complications, including intraoperative massive hemorrhage, interior alveolar nerve injury, mandibular angle fracture, and mental bone lateral wall perforation.

Object To study the chemical constituents of Stelmatocrypton khasianum (Benth.) H. Baill.. Methods Some constituents were isolated by chromatographic methods and identified by physicochemical constants and their structures were elucidated by spectral data. Results Seven compounds were isolated from the stem of S. khasianum and their structures were identified as ?-sitosterol-3-O-?-D-glucoside-6′-O-eicosanate (Ⅰ), 2?, 3?, 23-trihydroxy-olean-12-ene-28-oic acid (Ⅱ), 2?, 3?, 23-trihydroxy-urs-12-ene-28-oic acid (Ⅲ), ?-sitosterol-3-O-?-D-glucoside (Ⅳ), stearic acid (Ⅴ), glucose (Ⅵ), and sucrose (Ⅶ) respectively. Conclusion All compounds were obtained from this plant for the first time, and compound I is new.

AIM:To investigate the role of heme oxygenase (HO) in AngⅡ induced proliferation and hypertrophy of cultured vascular smooth muscle cells. METHODS:(1) Western blotting analysis was carried out to detect protein level of HO-1 in the tissues. (2) [3H]-TdR,[3H]-leucine incorporation was measured in cultured vascular smooth muscle cells. (3) 2',7'-dichlorofluorescin diacetate (DCFH-DA) as an index was used to determine the cellular reactive oxygen species (ROS) level. RESULTS:(1) No significant difference in HO-1 protein expression level between AngⅡ-stimulated and control groups was observed,but HO-1 protein level in Hemin-induced group was higher than that in other two groups (P

0.05). However, compound muscle action potential (CMAP) amplitude in ims injected group wa s si gnificantly higher as compared with the other two groups[ims injected group (12.50?2.06) mV, iv group (1.50?0.20) mV, control group (10.13?4.04) mV, F=6.347, P=0.033]. The MSC s were able to be observed only in ims injected tissues 3 weeks after implantati on (A large number of small undifferentiated cells were found outside the myofib ers and some were found between the cells.) The atrophy of gastrocnemius in ims injected group was much less severe than that of the other 2 groups. The diameter of muscle fibers was significantly longer on d60 (F=4.537,P=0.021).Conclusion:Intra- muscular injection of MSC was well distributed in denervated muscle, which provides a newway of nerve regeneration in the rat model of sciatic nerve injury.

METHODS: The changes in mean arterial pressure and heart rate as well as phenylephrine(PHE)-induced contraction in isolated aortic rings of HLL, ZnPPIX- treated rats were examined after intraperitoneal administration of HLL and carbon monoxide( CO). RESULTS: (1) Injection of exogenous CO resulted in a significant decrease in mean arterial pressure in Sham and 2K1C groups(P

Objective To evaluate DWI in the assessment of viability of hepatic alveolar echinococcosis (HAE) by comparing DWI with PET-CT results. Methods 18-fluorodeoxy glucose(18F-FDG) PET-CT and DWI(b values=0, 800 s/mm2) were retrospectively analyzed in 8 patients with clinically verified HAE. The metabolic activity of HAE lesions in both techniques were determined by two independent radiologists respectively. Kappa test was assessed between the results of two observers. Results Sixteen lesions (composed of 14 HAE and 2 cystic echinococcosis, CE) were detected. (1)Eight lesions (≥2 cm) showed perilesional hyper-signal intensity on DWI, mainly around the lesion bounding by normal liver parenchyma. One patient (≥2 cm) had oral drug therapy for three years, and the lesion showed discontinuous perilesional hyper-signal intensity on DWI after the therapy. Five lesions (<2 cm) were depicted as nodular high signal on DWI.(2)Eight lesions (≥2 cm) showed perilesional increased FDG uptake on PET-CT, while 5 lesions (<2 cm) displayed as“hot pot”. One patient (leison≥2 cm) who had oral drug therapy for three years showed hepatic defect without any FDG uptake in post-treatment PET-CT. Two CE lesions showed negative results on both DWI and PET-CT. The Kappa value of 0.880 indicated a good coincidence between DWI and PET-CT in depicting the metabolic activity of HAE (P=0.006). Conclusions This preliminary study showed the value of DWI in assessing HAE viability. DWI should be routinely used as one of the techniques in the evaluation of HAE.
