Purpose To investigate the clinicopathological changes of the diffuse-type giant cell tumor of the bone and joint. Methods 42 cases of the diffuse-type giant cell tumor of the bone and joint were studied and the follow-up data were reviewed. Results The male patients were 19 and the female were 23, with the male to female ratio of 1 ∶ 1. 2. The age of the patients was 8~69 years (the average age was 37. 6). It was displayed that the patients presented local pain and swelling (34 cases), including dysfunction (18 ca-ses) of the bone and joint. Clinically, the lesions located on the knee joint ( 71. 4%) in 30 cases, the hip and ankle in 9 cases (21. 4%), and the wrist elbow in 3 cases (7. 1%). 27 cases were examined by MRI. Among them, the diffuse-type giant cell tumor was diagnosed in 9 cases (33. 3%). The effusive lesions of the joint presented in 5 cases, the non-specific synovial lesions and others in 3 cases. The obviously diffuse hyperplasia of synovial cells with nodular growth pattern was found. However, a high proliferative in-dex of the tumor cells and the rich-cell tumor were found. But there was no tumor necrosis. Histopathologically, the tumor cells of dif-fuse-type giant cell tumor contained marked brown pigments, multinucleated giant cells formation and a lot of lymphocytes proliferation or follicular reaction in 17 cases (40. 5%) with invasive growth and involvement of the joint and surrounding tissue. 6 cases recurred (20%) , including 2 cases with 2 times. Conclusions The diffuse type-giant cell tumors most commonly involve the knee, followed by the hip and ankle. Preoperative examination of MRI can be help for the diagnosis of the tumor. Histopathologically, diffuse-type gi-ant cell tumor with synovial cells rich-hyperplasia and the villous structures formation more likely recur. The main biological character-istics of diffuse-type giant cell tumor are invasive growth pattern, usually into the soft tissue around the joints.

Hedgehog pathway is an osteogenesis-related signaling pathway . During embryonic development , it regulates the growth and proliferation of progenitor cells and tissue formation. This pathway can be activated during liver injury. Activated Hedge-hog signaling pathway is involved in many aspects of liver wound-healing responses, including hepatic progenitor cell pro-liferation, myofibroblast transdifferentiation, apoptosis of various types of liver cells, inflammatory reactions, and vascular remod-eling. This article reviews the research progress in the role of Hedgehog signaling pathway in liver injury and the underlying mechanisms. The potential drug targets are also discussed. This review is to provide novel insights into antifibrotic research and therapeutic targets.

BACKGROUND:Accumulating studies have confirmed the excellent effectiveness of local infiltration analgesia, but the literature analysis is mainly limited to within 1 day after total knee arthroplasty or shorter period.
OBJECTIVE:To study the effectiveness of local infiltration analgesia (LIA) at low concentration after total knee arthroplasty, and to observe the analgesic effect at rest and movement states.
METHODS:Thirty patients undergoing total knee arthroplasty were randomly al ocated to control group and LIA group, receiving oral non-steroidal anti nflammatory drug (celebrex) and low concentration of ropivacaine (0.1%) for epidural analgesia. Control group was injected with 0.9%saline 150 mL, while LIA group was injected with equal volume of solution include ropivacaine 300 mg, morphine 5 mg and epinephrine 10μg. The rest pain and motion pain of patients in two groups were evaluated at 6, 12, 24, 36, 48 hours after operation by using visual analogue scale. The incidence rate and degree of nausea, vomiting, numbness and muscle weakness of the legs were observed after operation. The incision healing was also recorded.
RESULTS AND CONCLUSION:Visual analogue scale pain scores in the LIA group were significantly lower than the control group at 6, 12, 24 and 36 hours at rest (P<0.05), at 6, 12, 24, 36, 48 hours on movement (P<0.05). At 6 and 12 hours, there was no difference in the rest and motion pains in the LIA groups (P>0.05). No patient appeared drowsiness, nausea, and vomiting in both groups. Two patients in each group complained of slight numbness in legs. No case influenced function exercise because of muscle weakness. Al the wounds healed and there were no incision infections in two groups. Combined with oral non-steroidal anti-inflammatory drug and low concentration of ropivacaine for epidural analgesia, the local infiltration analgesia technique in total knee arthroplasty is effective in early post-operative pain management, and produces no analgesia related adverse reactions.

Objective To assess the value of multi-slice spiral CTA in the diagnosis of iliac vein compression syndrome(IVCS)and secondary thrombosis.Methods The CTA data of 80 controls and 31 patients with IVCS conformed by DSA were retrospectively studied.The inner diameters of the compressed iliac vein in two groups were measured and compression ratios were calculated.The data were compared using t test and Wilcoxon test.The findings of CTA were compared with that of DSA and the accuracy of CTA was analyzed.Results For the control group,the inner diameters of left iliac vein in female group(7.0±2.5)mm were significantly less than that in male group(8.1±2.5)mm(t=2.42,P＜0.05).For the control group,the inner diameters of left iliac vein was(7.6±2.0)mm,and the compression ratios were 0 to 65.41%(median 27.65%).The compression ratios were no statistical differences between male group(0 to 61.36%,median 26.82%)and female group(0 to 65.41%,median 28.75%)(Z=-0.59,P＞0.05).For the patients group,the inner diameters of compression iliac vein was(2.7±1.1)mm.The compression ratios were 55.18% to 100%(median 76.12%).Both inner diameters and compression ratios were statistically different between the control and patients group(t=12.78,P＜0.05;Z=-8.18,P＜0.05).Fifteen of 31 cases with IVCS were accompanied with deep vein thrombosis.The left iliac veins were compress in 28 cases,while right iliac veins were compressed in 2 cases.The left and right iliac common veins were compressed by the left and right jliac common arteries in one case.The results of CTA were consistent with that of DSA in all cases.Conclusions CTA can not only measure the inner diameters of iliae vein compression and calculate compression ratios,but also demonstrate secondary thrombosis clearly.CTA is an effective examination in diagnosis of IVCS and secondary thrombosis.

OBJECTIVETo investigate the blood quality of blood banks.

METHODSHBsAg, Anti-HCV, Anti-HIV were detected by enzyme linked immunoadsorbent assay (ELISA). Treponema pallidum was detected by Trust or rapid plasma regain card test (RPR) before August 2001 and ELISA was used afterwards. Alanine aminotransferase (ALT) was detected by Reitman-Frankel before December 1999 and by continuous monitoring assay afterwards. Results were compared between (1) sampling and spot check, (2) different determent methods, (3) two kinds of reagents with different antigen coating.

RESULTSSeventy-two (8.28 per thousand ) of the 8,699 plasma samples were found unqualified with levels of anti-HCV, ALT, HBsAg, Treponema pallidum and anti-HIV 24 (2.76 per thousand ), 19 (2.18 per thousand ), 16 (1.84 per thousand ), 7 (0.80 per thousand ), 6 (0.69 per thousand ), respectively. There were significant differences between different determent methods and different reagents, but only ALT showed significant difference in the sampling and spot check.

CONCLUSIONThe unqualified samples were associated with testing methods, quality of reagents as well as ability and responsibility of the staff.

OBJECTIVETo explore the effect of emodin on endoplasmic reticulum (ER) stress of pancreatic acinar AR42J cells.

METHODRat pancreatic acinar AR42J cells were cultured in 6-well plates, and divided into the normal control group, the model group (with the final concentration at 1 x 10(-7) mol · L(-1) for cerulean and lipopolysaccharide at 10 mg · L(-1)) and the emodin group (10, 20, 40 μmol · L(-1)). Cells in each group were cultured in three multiple pores for 24 h, and their supernate was removed after cell attachment. The normal control group was added with haploids, the model group was added with the modeling liquid for haploids, and the treatment groups were added with different concentrations of emodin at 15-20 min before the modeling liquid. The cells were continuously cultured for 3 h under 37 °C and 5% CO2. Their intracellular protease and lipase expressions were detected with kits. The cellular morphology was observed under optical microscope. The level of calcium in endoplasmic reticulum was measured under laser confocal microscopy. Western blot assay were used to determine the protein expression of ER-related signaling molecules.

RESULTEmodin could significantly inhibit levels of amylase, lipase and intracellular calcium and ER.

CONCLUSIONEmodin could reduce pancreatic acinar cell injury induced by the combination of cerulean and lipopolysaccharide. Its action mechanism is correlated with the inhibition of intracellular calcium overload and ER stress.

To establish a method for the determination of astilbin, peoniflorin, rasmarinci acid, isofraxidin and liquiritin contained in Shaolin Xiaoyin tablets, in order to lay a foundation for designing late-stage dosage forms and clinical medication schemes. In this paper, efforts were made to establish a method for the determination of the blood concentration of the five components and study the in vivo pharmacokinetics in rats. The blood concentration was determined by HPLC. Phenomenex C18 column (4.6 mm x 250 mm, 5 microm) was adopted and eluted with methanol-acetonitrile-0.05% formic acid, the flow rate was 0.8 mL x min(-1), and the wavelength was 275 nm. The samples were processed by the solid phase extraction method. After oral administration of Shaoling Xiaoyin tablets, the rat bloods were collected at different time points to determine the blood concentrations. The experimental results showed that the baseline separation could be adopted for the five components, and astilbin, peoniflorin, rasmarinci acid, isofraxidin and liquiritin showed good linear relations within ranges of 2.48-248, 0.213 6-21.36, 0.531-53.1, 0.704-70.4, 0.253-25.3 mg x L(-1). All the five components could be absorbed in blood and excreted quickly. The method established in this paper is rapid and accurate, and could be used for in vivo analysis on preparations containing similar components. The main components in Shaoling Xiaoyin tablets could be absorbed and excreted quickly, and thus suitable to be made into sustained release tablets. Common preparations are required to be taken for 4-6 times a day.
