Objective To evaluate the treatment effects on schistosomiasis hepatic fibrosis with Dangguibuxue decoction.Methods Thirty-four rabbits weighing 2.0-2.5 kg were selected.The procedure for the model of schistosomiasis liver fibrosis was as follow.Thirty-four snails infected by schistosoma japonicum were placed in triangle flask to escape cercariain.Abdominal skin of each rabbit wag infected by 100 schistosoma japonicum cercariaes.All rabbits were housed in conventional cages at room temperature.After 13 weeks schistosoma japonicum infected,the rabbits'livers were examined by B-ultrasound examination every week.After 18 weeks of infection,B-ultrasound showed images of schistosomiasis liver fibrosis,the rabbits were thus identified as schistosomiasis liver fibrosis.Praziquantel Was as insecticide to treat rabbits.All rabbits were divided into treatment and control groups according to body weigh.The high and low dosage group were treated with Dangguibuxue decoction at 50 g/kg and 5 g/kg(n=11),respectively,and the control group with no treatment(n=12).Two groups were treated with Dangguibuxue decoction every day for 10 weeks.After 10 weeks of treatment,the rabbits were killed and the livers were obtained to go HE staining and histopathological examination under microscope.Results After 18 weeks of infection,B-ultrasound showed that the liver parenchyma Was coarse and net-shaped.having hyperechoie spots with lightbrand and facula.The liver's shape Was abnormal,portal and splenic vein diameter was widened.Histopathological examination showed that the high dosage group presented fibrosis,which was formed by collagen fiber extending to peripherM regions,low dosage group showed mild fibrosis,mild collagen fiber present with extension without compartment formation, while the control group presented severe fibrosis and severe collagen fiber present with a thickening of the partial compartments and the distribution of eggs nodules. The liver histopathological ranking results from different groups showed that the difference was significant (χ2= 13.585,P < 0.01), the difference between the treatment groups of high and low dosage and control group was significant,respectively(all P < 0.01 ). Conclusions The histopathology results showed that both high and low dosage Dangguibuxue decoction can reverse or eliminate schistosomiasis liver fibrosis in rabbits.

Objective To determine the significance and expression of S100A9 and NMP238 in cervical carcinoma with different concurrent chemoradiotherapy sensitivities. Methods Fresh carcinoma tissues were collected from untreated cervical carcinoma patients and preserved at -80 ℃. The tissues were classified into 2 groups:a high sensitivity group (HS) and a low sensitivity group(LS) according to their response to concurrent chemoradiotherapy. Protein was separated by 2-dimensional gel electrophoresis (2-DE). Peptide mass fingerprintings (PMF) were acquired by matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and the proteins were identified by data searching in the Mascot-database. Differential expressed proteins were assayed by Western blot and immunohistochemistry.Results Most of the gels were clear and were successfully and reproductively analyzed. Intensity and rate of S100A9 expression were higher in the HS group than in the LS group,and those of NMP238 expression were higher in the LS group than in the HS group. Conclusion S100A9 and NMP238 expression is associated with concurrent chemoradiotherapy sensitivity in cervical carcinoma.

BACKGROUND: The low survival rate of neuron cells is one of the main mechanisms of stem cell allograft, which might lead to the failure of allograft. Nuclear factor-KB (NF-kB) is one of main transcription factors for cell signaling transduction and participates in call proliferation and differentiation.OBJECTIVE: To study the differentiation of muscle-derived stem cells (MDSCs) into neuron-like cells induced by ciliary neurotrophic factor (CNTF) and Compound Salvia Miltiorrhiza Injection in vitro, and the expression of NF- kB.DESIGN, TIME AND SETTING: The experiment at cell molecular level was performed at the Oral Science Laboratory of the Second Affiliated Hospital of Liaoning Medical College from March to May 2008.MATERIALS: A total of 10 Sprague Dawley neonatal rats aged 7 days were supplied by Experimental Animal Center, Liaoning Medical University. CNTF (Sigma, USA) and Compound Salvia Miltiorrhiza Injection (Chiatai Qingchunbao Pharmacantical Co.,Ltd., China) were used in this study.METHODS: Rat MDSCs were harvested in vitro, pudfied by differential adherence and enzyme digestion, and incubated in 6-well plate. Samples in the induction group were incubated in DMEM containing CNTF for 24 hours. The medium was changed.Subsequently, samples were dnsed three times, and then incubated in serum-free DMEM supplemented with Compound Salvia Miltiorrhiza Injection for 5 hours. Samples in the control group were treated with serum-free DMEM.MAIN OUTCOME MEASURES: Neurofilament protein and NF-KB inhibitor protein expression were detected using reverse transcription-polymerase chain reaction (RT-PCR) and Westem blotting.RESULTS: No neurofilament protein expression was found in MDSCs before induction, and neurofilament protein-positive MDSCs were detected following induction. Results of gel electrophoresis and Westam blot showed that no significant differences in NF-kB inhibitor protein expression were determined in the control group, and NF-kB inhibitor protein expression was significantly decreased in the induction group after induction.CONCLUSION: CNTF and Compound Salvia Miltiorrhiza Injection could inhibit the activation of NF-kB and induce the differentiation of MDSCs into neuron-like cells.Zeng XY, Wang W, Sun L, Zhang L, Zeng LD.Differentiation of muscle-derived stem cells into neuron-like cells induced by ciliary neurotrophic factor and Compound Salvia Miltiorrhiza Injection in vitro.Zhongguo Zuzhi Gongcheng Yanjiu yu Linchuang Kangfu.2009;13(27): 5336-5340.

Excessive medical treatment goes against the human rights of patients and therefore must be stopped.Main reasons include the impulse of existing medical benefit mechanism,the morality decline of medical staff,and patients' eagerness to shake off physical pain and psychological advocating for high-cost medical expenditure.This paper also comes up with relevant countermeasures including reversing the current healthcare mechanism,establishing an evaluation system for medical ethics of medical staff,and building up a monitoring mechanism for the development of clinical guidelines of evidence-based medicine.

Objective Amblyopia is common disease in children. It can cause visual suppression that damage binocular vision function especially to the development of stereopsis. The objective of this study was to investigate the stereoscopic vision in children with different types and degrees of amblyopia. Methods This is a clinical retrospective comparative analysis. 178 children with amblyopia from Sichuan Provincial Corps Hospitial CAPF were enrolled in this study. Approximation zero disparity, crossed disparity, uncrossed disparity were examined with Yan' s stereogram. The classification of stereogram based on the criteria of Okuda. The degree of amblyopia was graded based on the corrected vision acuity. Results The differences in the eyes and percentage of approximation zero disparity, crossed disparity, uncrossed disparity among refractive amblyopia group, anisopia amblyopia group and strabismic amblyopia group were statistically significant, respectively(χ~2 =13. 979, P =0. 001; χ~2 = 15. 198, P = 0. 001 ; χ~2 =6. 974, P = 0. 031) . Approximation zero disparity, crossed disparity in mild amblyopia were better than of medium amblyopia in ametropic amblyopic children (P ＜ 0. 05) . No statistically significant difference in the eye number and percentage of uncrossed disparity was found between mild and moderate refractive ametropia (P ＞ 0. 05) . The same outcomes also were seen in approximation zero disparity, crossed disparity, uncrossed disparity between mild and medium anisopia amblyopia (P ＞ 0. 05) . No statistically significant differences in the eye number and percentage of approximation zero disparity, crossed disparity were found between mild and moderate strabismic amblyopia (P ＞0. 05) . Conclusion Amblyopia affects the development of stereoacuity. Amblyopia is aggravated with the increase of amblyopia degrees. The influence of amblyopia on stereoscopic vision is most mild in refractive ametropic and most serious in strabismic amblyopia.

OBJECTIVE:To explore the protective effect of L-ornithine-L-aspartate on ischemia-reperfusion injury after partial hepatectomy. METHODS:104 patients underwent partial hepatectomy(vessel occlusion in portal fissure)were randomly divided in-to control group(53 cases)and trial group(51 cases). Control group was given routine liver-protective drugs,and trial group was additionally given L-ornithine-L-aspartate 10 g added into 5%Glucose injection 250 ml intravenously before surgery,for 7 consecu-tive days. The fasting peripheral venous blood was collected in 2 groups on first day before surgery and first,forth and sixth day af-ter surgery to detect liver function;the changes of main aminopherase index(ALT and AST)were compared between 2 groups at different portal fissure vessel occlusion time after surgery. RESULTS:There was no statistical significance in the difference of liver resection range,blood loss,first porta hepatis vessel occlusion time and anesthesia time in both groups during operation (P>0.05). Compared to before surgery,liver function indexes raised to different extent in 2 groups after surgery,with statistical signifi-cance(P<0.05). The levels of AST and ALT in trial group were significantly lower than in control group on first,forth and sixth day after surgery,while albumin level was significantly higher than control group,with statistical significance(P<0.05). Total bili-rubin levels of both groups were approximate basically,there was no statistical significance(P>0.05). Among those patients under-went porta hepatis vessel occlusion with Pringle method and with occlude occlusion time ≥15 min,the AST and ALT level of con-trol group was higher than those of trial group after surgery,but albumin level was below trial group,with statistical significance (P<0.05). CONCLUSIONS:L-ornithine-L-aspartate could improve liver function fast and effectively for partial hepatectomy pa-tients,especially for the patients underwent porta hepatic vessel occlusion with Pringle method for a long time(obvious ischemia-re-perfusion injury).
