OBJECTIVETo evaluate clinical effect and safety of floating needle therapy and duloxetine in treating patients with persistent somatoform pain disorder (PSPD).
METHODSTotally 108 PSPD patients were randomly assigned to the floating needle treatment group, the duloxetine treatment group, and the placebo treatment group, 36 in each group. Patients in the floating needle treatment group received floating needle therapy and placebo. Those in the duloxetine treatment group received duloxetine and simulated floating needle therapy. Those in the placebo treatment group received the placebo and simulated floating needle therapy. All treatment lasted for six weeks. Efficacy and adverse reactions were evaluated using Simple McGill pain scale (SF-MPQ) and Treatment Emergent Symptom Scale (TESS) before treatment and immediately after treatment, as well as at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Hamilton Depression Scale (HAMD, 17 items), Hamilton Anxiety Scale (HAMA) were assessed before treatment and at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Patients in the floating needle treatment group and the duloxetine treatment group with the total reducing score rate of SF-MPQ in Pain Rating index (PRI) ≥ 50% after 6 weeks' treatment were involved in the follow-up study.
RESULTS(1) Compared with the same group before treatment, SF-MPQ score, HAMD score and HAMA total scores all decreased in all the three groups at the end of 1st, 2nd, 4th, and 6th week of treatment (P < 0.05, P < 0.01). Besides , each item of SF-MPQ significantly decreased immediately after treatment in the floating needle treatment group (P < 0.01). Compared with the placebo treatment group, SF-MPQ, HAMD, and HAMA total score in the floating needle treatment group significantly decreased after 1, 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). SF-MPQ score, HAMD score and HAMA total score in the duloxetine treatment group also significantly decreased after 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). (2) There were 3 patients (8.3%) who had adverse reactions in the floating needle treatment group, 17 (50.0%) in the duloxetine treatment group, and 7 (21.2%) in the placebo treatment group. Compared with the placebo treatment group, the incidence of adverse reaction increased in the duloxetine treatment group (χ² = 6.04, P < 0.05). Besides, it was higher in the duloxetine treatment group than in the floating needle treatment group (χ² = 14.9, P < 0.05). (3) There were 19 patients in the floating needle treatment group and 17 patients in the duloxetine treatment group involved in the follow-up study. Compared with 6 weeks after treatment, no significant difference was observed at 3 and 6 months after treatment in the score of SF-MPQ, HAMD, and HAMA in the floating needle treatment group and the duloxetine treatment group. No significant difference was observed between the two groups (P > 0.05). There were 5 patients (29.4%) who had adverse reactions in the duloxetine treatment group, and no adverse reactions were observed in the floating needle treatment group. The adverse reaction rate was significantly different between the two groups (χ² = 4.26, P < 0.05).
CONCLUSIONSFloating needle therapy and duloxetine were effective in treatment of patients with PSPD. However, floating needle therapy could relieve pain more rapidly than duloxetine, with obviously less adverse reactions.

PURPOSE: Treatment of Kawasaki disease with intravenous gamma globulin(IVGG), together with aspirin, has been dernonstrated to be safe and effective in preventing coronary artery lesion and systemic inflarnmation, but optimal IVGG dosage and administration method are still controversial. We compared the therapeutic efficacy and clinical response of single IVGG 1g/kg to that of IVGG lg/kg for comparable risk group of Kawasaki disease. METHODS: We conducted a prospective study involving 63 children with Kawasaki disease requiring IVGG treatment(Harada score> or =4) at Chungnam National University Hospital from February 1996 to January 1999. The children were assigned to receive IVGG either as a single infusion of 1g/kg(A group, 32 person) or 2g/kg(B group, 31 person) and aspirn(100mg/kg/day through acute phase, then 3 to 5mg/kg/day for 8 weeks of duration). RESULTS: There were no significant difference between the two groups according to clinical and laboratry data, including coronary artery lesions(group A, 31.3% and group B, 29.0%) before treatment. After IVGG treatment ratio of complication with coronary artery lesion(group A 1/32=3.1% and group B, 2/31=6.5%) and that of retreatment(group A, 4/32=12.5%, group B, 2/31=6.5%), duration of fever(group A, 1.3+/-1.6 days and group B, 0.7+/-1.4 days), hospital stay(group A, 7.0+/-1.4 days and group B, 6.5+/-2.0 days), laboratory finding and side effects of IVGG were not significantly different(P>0.05). The total dosage of IVGG was significantly lower in group A than group B(group A, 1.16+/-0.37g/kg, 375,421+/-207,351won and group B, 2.10+/-0.40g/kg, 641,498+/-274,750won (P<0.05). CONCLUSION: The therapeutic efficacy and clinical response of single 1g/kg therapy are comparable to that of single 2g/kg therapy.

OBJECTIVETo study the effect of melatonin (MLT) in in vitro apoptosis of hepatocarcinoma cells and its mechanism.
METHODSThe apoptotic cells, bcl-2 and bax were detected through immunocytochemical method (ICC) and Tolt-mediated x-duTP nick end labeling (TUNEL). Computer image analysis system was used to quantify the expression of bcl-2 and bax by detecting the absorbance value of positive products. Apoptosis index (AI) was used to quantify the number of apoptotic cells.
RESULTSIn vitro, AI increase was both concentration- and time-dependent through TUNEL. During the same duration, AI of medium dose group was higher than that of low dose and control group (P < 0.05); AI of high dose, medium dose and 5-Fu group were higher than those of low dose and control group (P < 0.01), however, there was no significant difference between the low dose and control group (P > 0.05). At the same dose, in high dose, medium dose and 5-Fu group, the change of AI showed significant difference from 24 to 36 hours (P < 0.05). The expression of bcl-2 was down-regulated as the MLT increased, and there was significant difference between the low dose and control group (P < 0.01). But, the expression of bax was up-regulated as the dose of MLT increased, showing significant difference between the high dose and control groups (P < 0.01). As time went on, the expression of bcl-2 was decreased and in every group, with the change in absorbance value of bcl-2 significantly different from 24 to 36 hours (P < 0.05), whereas that of bax remained almost unchanged. The ratio of bax/bcl-2 was increased with the increase in the concentration of MLT.
CONCLUSIONMelatonin may induce apoptosis in the hepatocarcinoma cells which is concentration- and time-dependent, in which bcl-2 and bax are involved.

OBJECTIVETo study the different features of hyperplasia in castrated and uncastrated mice after testosterone (T) treatment.
METHODSForty-eight BALB/c mice were randomly divided into 6 groups of 8 in each: castrated (A), uncastrated (B) , castrated + low T (C), uncastrated + low T (D), castrated + high T (E), uncastrated + high T (F). Groups C and D were treated with testosterone solution at the dose of 12.5 mg/(kg d) and Groups E and F at 125 mg/(kg d) for 20 consecutive days, while Groups A and B received saline only. All the mice were sacrificed on the 21st day, their ventral and dorsal prostate glands weighed and their pathological features studied.
RESULTSAtrophic prostates were observed in Group A, but normal in Group B; prostatic hyperplasia was found in both Group C and D, but more obvious in the latter (P <0.05); and a slightly higher degree of hyperplasia was noted in Groups E and F than in C and D. There was an increase in serum T and vascular endothelial growth factor (VEGF) concentration and a decrease in serum estrogen (E2) concentration in the testosterone treated groups.
CONCLUSIONBoth castrated and uncastrated mice develop prostate hyperplasia after short-term testosterone treatment, although in different degrees and with different features, which may help further the studies on the association of castration and androgen with prostate diseases.

Objective:To compare the detection success rates (DSRs) of different kinds of near-infrared spectrum non-invasive hemoglobin monitors in high-altitude environments.Methods:One hundred and forty-four healthy volunteers of either sex, aged 18-50 yr, were assigned to one of 3 groups using a random number table method: simulated high-altitude 3 500 meter group ( n=35), 4 000 meter group ( n=55) and 4 500 meter group ( n=54). Hemoglobin was detected by Radical-7, NW-9002SHM, A5 and TensorTip MTX type hemoglobin monitors in plain environment and simulated environment at different altitudes, and the DSRs were compared.Logistic regression analysis was conducted to identify the risk factors affecting the success rate of instrument detection, and the cut-off value was determined by ROC curve and the Youden index. Results:In the simulated high-altitude environment of 3500, 4000 and 4500 m, the DSR of TensorTip MTX was significantly higher than that of Radical-7, NW-9002SHM and A5 ( P<0.001), and there was no significant difference in the DSR among Radical-7, NW-9002SHM and A5 ( P>0.05). Low SpO 2 was the main factor affecting the DSRs of the Radical-7, NW-9002SHM and A5 type hemoglobin monitor in high-altitude environment ( P<0.001), and the cut-off value of SpO 2 in determining the success of detection was 88.5%, 87.5% and 89.5%, respectively.The DSR of TensorTip MTX was not affected by low SpO 2. Conclusions:The DSR of TensorTip MTX hemoglobin monitor is minimally affected by the high-altitude environment and can be preferred in the absence of oxygen supply; when Radical-7, NW-9002SHM or A5 hemoglobin monitor applied in high-altitude environments, oxygen saturation needs to be increased to ensure a high DSR.

OBJECTIVETo explore the effect of anhydroicaritin phytosomes (AIP) in preventing and treating bone loss and enhancing bone quality in ovariectomized osteoporosis rats.
METHODSeventy-two SD female rats were randomly divided into 6 groups: the sham group, the model group, the estrogen group and AIP groups (low, middle, high). The sham group was only sham operated, and the remaining five groups were ovariectomized. One week after the ovariectomy, the rats were given 17 beta-estrogen and AIP (15, 30, 60 mg x kg(-1)) for consecutively three months, during which period their serum calcium (s-Ca), serum phosphorus(s-P), alkaline phosphate (ALP), urine calcium (u-Ca), urine phosphorus(u-P), urinary deoxypyridinoline (D-Pyr) and creatinine (Cr) were detected. Subsequently, rats were sacrificed, and their thighbone, second lumbar vertebrate and forth lumbar vertebrate were collected to detect bone mineral density (BMD), bone calcium (b-Ca) and phosphorus (b-P), biomechanical properties and bone histomorphometric parameters.
RESULTCompared with the sham group, the model group showed a significant increase in serum ALP, u-Ca and D-Pyr /Cr, and reduction in BMD of femur, b-Ca and b-P, biomechanical properties (elastic load, maximum load, break load, stiffness), static parameters (total tissue area, trabecular area, trabecular perimeter) and dynamic parameters (% L Pm, BFR/BV and BFR/ TV), with metratrophia. Compared with the model group, ALP high and middle-dose groups and the estrogen group showed a decrease in serum ALP, u-Ca and D-Pyr/Cr, and growth in BMD of femur, b-Ca and b-P, biomechanical properties of the forth lumbar vertebrae (elastic load, maximum load, break load, stiffness), static parameters (total tissue area, trabecular area, trabecular perimeter) and dynamic parameters (% L Pm, BFR/BV and BFR/TV). The beta-estrogen group showed endometrial hyperplasia, whereas AIP groups showed no hyperplastic change.
CONCLUSIONAIP could inhibit enhanced bone turnover induced by ovariectomy, improve BMD the biomechanical properties of vertebrae, without any stimulation on uterus.

OBJECTIVETo create a convenient method to establish an alcoholic liver fibrosis model in mice and use it to explore the putative pathogenic mechanisms involving the immunomodulatory proteins osteopontin (OPN) and transforming growth factor-betal (TGF-beta1).
METHODSForty C57BLI6J mice were fed the Lieber-DeCarli 4% ethanol-containing liquid diet for four weeks, followed by an additional four weeks of the 4% ethanol diet combined with intraperitoneal injection of carbon tetrachloride (CC14 5% solution in olive oil; 2ml/ kg body weight, 2 times/week) to induce alcoholic liver fibrosis. Control groups (n = 6 each) included: normal diet; normal diet plus CCl4 injections; ethanol diet alone; ethanol diet plus solvent (olive oil) injections. Model establishment was monitored by sacrificing six mice at model inception (week 0), and weeks 4, 5, 6, 7, and 8 of modeling to collect liver tissues and blood for histological and biochemical analyses. Extent of hepatic steatosis, inflammation, and fibrosis was assessed by hematoxylin-eosin and Masson staining. Liver function markers, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, were tested by automated enzymatic assays. Alpha-smooth muscle actin (alpha-SMA) expression was detected by immunohistochemistry. The mRNA and protein expression of OPN and TGF-beta1 was detected by real-time quantitative reverse transcription-PCR and western blotting, respectively. Significance of differences between multiple groups was assessed by one-way ANOVA analysis followed by least significant difference t-test or Kruskal-Wallis H test followed by the Mann-Whitney U test.
RESULTSCompared to the control groups, the group of mice administrated ethanol and CCl4 developed mild to moderate hepatic steatosis at week 4 of modeling, progressive necroinflammation and perisinusoidal and portal fibrosis from weeks 5-8, and irregular necrosis and bridging fibrosis at week 8. In addition, the model group showed progressive up-regulation of a-SMA expression in the activated hepatic stellate cells (HSCs) and fibrotic areas from weeks 5-8. Both hepatic OPN and TGF-beta1 showed significantly increasing trends in mRNA and protein expressions from weeks 5-8 (OPN mRNA: 1.83 +/- 0.25, 2.94 +/- 0.19, 3.45 +/- 0.31, and 5.99 +/- 0.17 (F= 476.27, P < 0.001); OPN protein: 0.52 +/- 0.06, 1.02 +/- 0.10, 1.52 +/- 0.11 and 1.50 +/- 0.08 (F= 298.03, P< 0.001); TGF-beta1 mRNA: 13.19 +/- 0.40, 3.31 +/- 0.28, 1.58 +/- 0.18 and 2.08 +/- 0.26 (F= 85.55, P < 0.001); TGF-P31 protein: 1.26 +/- 0.16, 0.96 +/- 0.12, 1.09 +/- 0.25 and 1.10 +/- 0.20 (F = 43.64, P < 0.001).
CONCLUSIONFeeding C57BL/6J mice the Lieber-DeCarli ethanol-containing liquid diet combined with CCl4 intraperitoneal injection is a convenient method to establish a model of alcoholic liver fibrosis within a relatively short amount of time (eight weeks). Progression of alcoholic liver fibrosis is accompanied by increased hepatic expression of OPN and TGF-beta1, which may contribute to the pathogenic mechanism of this disease and may be targets of future molecular therapies.
