Acupuncture has become a popular alternative modality in the treatment of back pain. However, few have reported complications related to this treatment modality. This study reports a rare case of septic arthritis of the lumbar facet joints, developing after acupuncture, and its devastating effects upon the patient. A 68-year-old female developed septic arthritis of the lumbar facet joints after acupuncture for symptomatic control of lumbar spondylosis and stenosis while waiting for surgery. Subsequently, successful control of the infection required a total of 4 hospital admissions over a 2-year period, a CT guided spinal biopsy and 6 months of antibiotics.

Objective To investigate the expressions and significance of transforming growth factor-beta 1(TGF?1) and its typeⅡ receptor(TGF?RⅡ) in experimental rat ascending aortic aneurysm of rat model.Methods The rat ascending aortic aneurysm models were made by banding ascending aorta of young Wistar rats.The ascending aortas were taken 4 months after operation.Immunohistochemistry staining and Western blotting were used to investigate the expressions of TGF?1 and TGF?RⅡ.Result Immunohistochemistry staining results showed that TGF?1 expressed in all layers of the aortic aneurysm and the control.TGF?RⅡ was extensively located in the hyperplastic intima and tunica media smooth muscle cells in the aortic aneurysm,while there was only a little positive staining in the control group.Western blotting results indicated that the expression levels of TGF?1 and TGF?RⅡ in the aortic aneurysm were stronger than the control,P

AIM: To study the effect of high fat diet on the expression of sterol regulatory element biding protein-1 (SREBP-1) and transforming growth factor β_1 (TGF-β_1) in renal tubular cells and rosiglitazone intervention. METHODS: Wistar rats were treated with high fat diet and rosiglitazone for 3 months. The serum glucose, serum insulin and serum triglyceride were detected. Oil Red O staining was used to observe the renal lipid deposit and Masson staining was for the detection of ECM accumulation. SREBP-1, TGF-β_1 and FN protein were determined by the methods of immunohistochemistry and Western blotting. SREBP-1 mRNA was detected by in situ hybridization. RESULTS: Rosiglitazone prevented effectively the increase in serum glucose, serum insulin and serum triglyceride resulted from high fat diet. High fat diet led to lipid droplet formation in renal tubular cells and interstitial ECM accumulation, which was decreased by rosiglitazone treatment. Compared to normal rats, SREBP-1 protein and SREBP-1 mRNA showed high expressions in high fat diet rats that were lowered by rosiglitazone. The precursor segment and mature segment of SREBP-1 protein were decreased by 27.39% and 27.32%. Similarly, the high expressions of TGF-β_1 and FN protein in kidney of high fat diet rats were also prevented by rosiglitazone intervention. Compared to high fat diet rats, the expression of TGF-β_1 in rosiglitazone treatment rats was lowered by 19.14%. CONCLUSION: Rosiglitazone prevents effectively the over-expression of SREBP-1 and TGF-β_1 in renal tubular cells, and decreases lipid accumulation and ECM production in rats fed with high fat diet.

Objective To approach the value of combination mode of different CT post-processing technique in diagnosing rib fine fracture.Methods 98 patients suspected with rib fractures underwent multislice spiral CT(MSCT) scanning,and CT features of rib fractures were observed with the combination of three different images:(A)volume rendering(VR),curved planar reformation(CPR) and axial view;(B)maximum intensity projection(MIP),CPR and sxial view;and(C) VR+MIP,CPR and axial view.The results were respectively recorded.Results 265 rib fine fractures were found among 98 patients.The detecting rate of fine fractures with C group was higher than that with A group (χ~2＝6.67,P＜0.01) and B group (χ~2＝6.75,P＜0.01).Conclusion MSCT four step observation method can improve the detecting rate of rib fine fracture,that is of important clinical value.

significantly increased (all P < 0.01). Following SREBP-1 was down-regulated by siRNA, high glucose-stimulated TGF-β1 and FN protein expressions were decreased by 17.9% and 24.6% ,respectively(all P<0.01).

Objective To explore the dose-effect relationship between water fluoride levels and hepatic damage in children and observe the difference in hepatic function between high-loaded fluoride people and dental fluorosis people in the same water fluoride level region. Methods 210 children were selected and divided into seven groups according to drinking water fluoride concentrations and whether they suffered from dental fluorosis. Urine and serum fluoride content total protein TP and albumin ALB content and activities of ALT AST and LDH in serum were determined. Results Both of urine and serum fluoride of high fluoride people and dental fluorosis people were higher than those of the control moreover fluoride contents in urine and serum increased gradually with the increase of fluoride level in drinking water. No significant differences were seen in serum TP ALB ALT and AST levels among groups. Serum LDH activities significantly increased in dental fluorosis people from area of 2.58 mg/L fluoride in drinking water and in two groups from area of 4.51 mg/L fluoride. Moreover there was an obvious dose-effect relationship between the drinking water fluoride concentration and LDH activity. Conclusion If the concentration of fluoride in drinking water exceed 2.0 mg/L it will cause hepatic damage in children with an remarkable dose-effect relationship. The degree of hepatic damage is related to not only water fluoride level but also the condition with or without dental fluorosis.

Objective To investigate the role of fibroblasts in nonunion fracture healing using extracorporeal shock wave(ESW) treatment. Methods Thirty healthy rabbits were selected to make the models of non-union fractures of the right tibias, which were then held apart by external fixation. 12 weeks after the operation, hypertrophic non-unions were confirmed in 27 of the rabbits by radiography. These 27 were divided randomly into a treatment group and a control group. The test animals were treated with ESW under general anaesthesia. The two ends of the nonunion fracture were shocked 1 000 times at 0.54 mJ/mm2 and a frequency of 60 times/minute. The nonunions of the control group were treated with external fixations only. Histological examination and transmission electron microscopy(TEM) were conducted after 2 and 6 weeks. Standardized radiographs were taken after 12 weeks of the shock wave treatment. Results ESW induced microfractures, which initiated the healing process of the nonunionfractures. X-rays showed that 8 of the 9 fractures of the treatment group had healed after 12 weeks of EWS treatment, but only 3 of the 9 in the control group had healed. Statistical analysis showed that this difference was significant at the 5% level. After 2 weeks of ESW treatment, TEM showed many collagen fibers around the fibroblasts in the treatment group, with characteristic and periodic transverse lines. This indicated that the fibroblasts had been secreting collagen fibers as osteoblasts. Six weeks later, osteoblasts and fibroblasts had formed bone lacunes, and they had become osteocytes. However osteogenetic activates were not found in the control group. Conclusions Fibroblasts are activated by ESW to better form bone tissue. This process plays an important role in rebuilding broken bones.

A spectrophotometric method for the determination of calcium in milk, hair and urine was developed using metal complezing dye orthocresolphth-alein complexone(OCPC).The organic matter in the tested sample was destroyed by digestion. An aliquot of the digested solution was mixed with color developing reagent, alkaline OCPC, cantaining 8-quinolinol to suppress interference such as magnesium, and the absorbance was measured at 570 nm.The coefficients of variation were 0.87, 3.6 and 1.2% for milk, hair and urine samples; and the analytical recoveries of calcium from milk, hair and urine averaged 100.4, 101.0 and 98.5% respectively. The calcium content of milk and hair determined by this method was closely correlated with that of the ICP-AES method (r =0.994, p
