Objective To study the effects of recombinant ciliary neurotrophic factor(CNTF) on expression of growth related proteins in related neurons after sciatic nerve repair in rats. Methods After a segment of the sciatic nerve of the rat was removed, the distal and proximal ends were sutured into a recombinant CNTF-containing silicone tube. Growth associated protein 43 ( GAP-43 ) and somatostatin (SOM) in the L4 spinal cord, L4 or L5 spinal ganglia were examined and measured by immunohistochemistry and in situ hybridization using computerized image processing system. Results An increase in the GAP-43 immunoreactivity in the large, medium neurons of spinal anterolateral nucleus was more significant in the CNTF-treated group compared with those in the 0.9% saline (SAL) -treated group, while a decrease in SOM mRNA hybridization signals in those neurons were more significant in the CNTF-treated group. There were no significant differences in the aforementioned immunoreactivity and hybridization signals of spinal ganglia between the CNTF-treated group and the SAL-treated group. Conclusion The results suggest that recombinant CNTF administration up-regulate GAP-43 expression and down-regulate SOM mRNA expression in the related motor neurons, but not sensory neurons, after reconnection of transected sciatic nerve.

The effect of water extracts of Euphorbia hirta on the histological features and expressions of matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) in the rat articular cartilage was investigated. Arthritis was induced in rats using Freund's Complete Adjuvant containing heat-killed M. tuberculosis, and treated with water extracts of E. hirta. Paraffin tissue sections of the arthritic joints were evaluated. The extent of cartilage degeneration was found to be greatest in rats treated with the highest dosage of E. hirta, followed by rats in the untreated group. Rats treated with the intermediary and low dosages of Euphorbia hirta showed improved histology. MMP-13 levels were found to be decreased with decreasing dosages of E. hirta. TIMP-1 levels were found to increase with decreasing dosages of E. hirta. MMP-3 levels fluctuated without any appreciable pattern. Low dosages of E. hirta seem to be beneficial in reducing cartilage degeneration in cases of arthritis.

OBJECTIVETo explore treatment methods for patients with severe aplastic anemia (SAA) failing in immunosuppressive therapy (IST).

METHODSTotally 62 SAA patients failing in IST were treated by integrative medicine (IM). The treatment course was divided into three stages: the critical emergency stage, the improvement stage, and the recovery stage. In the critical emergency stage, patients were treated with Lingyang Yigui Decoction (LYD, consisting of 1.2 g antelope horn, 6 g coptis chinensis, 12 g stir-baked Fructus Gardeniae, 30 g rehmannia rhizoma, 50 g lalang grass rhizome, 9 g amur corktree bark, 12 g Cortex Moutan, 9 g ass-hide gelatin, 30 g red date, 6 g prepared licorice root, etc.) and Erzhi Busui Decoction (EBD, consisting of 120 g glossy privet fruit, 100 g eclipta prostrata, 24 g prepared Gold Theragran, 12 g fructus lycii, 90 g rehmannia rhizoma, 60 g astragalus, 9 g Angelica sinensis, 9 g ass-hide gelatin, 30 g honeysuckle flower, 12 g lotus plumule, and so on) alternatively, one dose daily, decocted twice, taken in two portions. Meanwhile, 50 mg Testosterone Propionate was intramuscularly injected every other day to the improvement stage. Those with fever were treated with LYD by adding 60 g gypsum, 60 g common anemarrhena, 30 g dandelion, 30 g bittersweet herb, 30 g blackend swallowwort root and rhizome, 15 g hemsley rockvine root tuber, and so on. In the improvement stage patients were treated with Jixueteng Compound (Jixueteng Zhengyang Decoction was administered to those of Shen-yang deficiency syndrome: consisting of 100 g spatholobus suberectus, 60 g astragalus, 3 g red ginseng, 12 g psoralea corylifolia, 18 g dodder seed, 12 g angelica, 18 g Herba Epimedii, 6 g common fenugreek seed, 24 g Gold Theragran, 30 g glossy privet fruit, 30 g eclipta prostrata, 6 g dried human placenta, and so on). Meanwhile, 50 mg Testosterone Propionate was intramuscularly injected every other day. Jixueteng Yijing Decoction was administered to those of Shen-yin deficiency syndrome: consisting of 100 g glossy privet fruit, 100 g eclipta prostrata, 90 g rehmannia rhizoma, 30 g spatholobus suberectus, 12 g dodder seed, 6 g psoralea corylifolia, 30 g prepared Gold Theragran, 9 g ass-hide gelatin, 9 g fructus lycii, 24 g Salvia miltiorrhiza, 30 g astragalus, 6 g angelica, and so on), one dose daily, decocted twice, taken in two portions. The treatment lasted to the recovery stage. The medication was gradually reduced to the follow-ups of drug discontinuance. Results After 6 -57 months of treatment, 12 patients (accounting for 19.4%) were basically cured, 14 (22.6%) relieved, 8 (12. 9%) markedly improved, 28 (45.2%) ineffectively, with the total effective rate of 54. 8%. Totally 23 patients had the body temperature ranging 37.6-38.5 degrees C at the first visit to our hospital. They took 2 h- 6 days to have pyretolysis ( <37.5 degrees C) after treatment. Twenty patients with body temperature higher than 38.5 degrees C took 4 h - 5 days to have pyretolysis after treatment. Totally 26 patients suffering from IST induced abnormalities of liver and renal functions (ALT, AST, BUN, and Cr) at the first visit were treated by IM for 2 months. They were restored to the normal levels in 25 cases.

CONCLUSIONSThe treatment of SAA failing in IST had its specificity. The staging targeted treatment is in line with its pathophysiology. The key points for its treatment might be lie in the improvement and protection of hematopoietic microenvironment of bone marrows. The antisepsis and anti-inflammation of Chinese herbs hindered its aggravating tendency.

Objective To analyze the treatment outcome and related influencing factors of Tibet- an nationality new smear-positive pulmonary tuberculosis patients in Qinghai Province，so as to provide evidence for tuberculosis control and treatment among Tibetan population． Methods Statistical analysis was conducted on 5 564 Tibetan nationality new smear-positive pulmonary tuberculosis cases in Qinghai province who were reported in the China Tuberculosis Information Management System and approved to receive treatment from 2008 to 2017． The main influencing factors were detected by unconditional Logistic regression model analysis，dependent variable was successful treatment or not，independent variables were other factors related to the treatment outcome． Ｒesults The treatment success rate of Tibetan nationality new smear-positive pulmonary tuberculosis cases was 87. 1% ( 4 848 /5 564) ，and the adverse outcome rate was 12. 9% ( 716 /5 564) ． Unconditional Logistic regression model analysis indicated that non-full- course supervision management，living in agricultural and pastoral area，having severe disease，floating population，and age older than 60 years were risk factors of adverse outcome． The odds ratio( OＲ) 95% confidence interval( CI) of the above risk factors were 13. 044( 10. 671-15. 944) ，2. 305( 1. 703-3. 119) ， 2. 090( 1. 346-3. 243) ，1. 967( 1. 443-2. 682) ，and 1. 909( 1. 410-2. 586) ． Clinical consultation，farmers and herdsmen were protective factors． The OＲ( 95% CI) were 0. 451( 0. 375-0. 543) ，and 0. 786( 0. 627- 0. 985) ． Conclusions Treatment success rate of Tibetan nationality new smear positive pulmonary tuberculosis cases was low． Therefore，the directly observed treatment short-course ( DOTS) strategy should be strictly implemented and the full-course supervision management should be strengthened to improve the treatment success rate． More attention should be paid to the elderly，severe，floating，agricultural and pastoral populations among the Tibetan population．

OBJECTIVETo study the effect of juglone on the ultrastructure of human liver cancer BEL-7402 cells.

METHODSBEL-7402 cells were incubated in the presence of 12.5 micromol/L juglone for 24 h, and fixed in 2.5% glutaraldehyde for HE staining and Coomassie brilliant blue staining and scanning electron microscopy.

RESULTSIncubation with juglone resulted in obvious changes in the cell morphology and cytoskeletal alterations of the cells. Scanning electron microscopy revealed reduced volume of the cell bodies, dissociation of the cells, curling and malformation of the microvilli on the cell surface with rupture of the intercellular junction and enlargement of the intercellular space. The formation of apoptotic bodies was observed. Transmission electron microscopy showed expansion of the endoplasmic reticula, mitochondrial cristea disintegration, nucleolar fragmentation and formation of the apoptotic bodies after the exposure to juglone for 24 h.

CONCLUSIONJuglone can cause ultrastructural changes of human liver cancer BEL-7402 cells and induce their apoptosis.

OBJECTIVETo evaluate the effectiveness of anterior versus posterior surgical treatments of thoracolumbar fractures.

METHODSRandomized controlled trials (RCTs) and clinical controlled trials (CCTs) were identified from MEDLINE (1966 - 2006.7), EMBASE (1966 - 2006.7), PubMed (1996 - 2006.7), Cochrane Library (Issue 2, 2006).We hand-searched Chinese Journal of Orthopedics (from establishment to May 2006) and Orthopaedic Journal of China (from establishment to May 2006). RCTs and CCTs were included. Data were extracted by two reviewers with designed extraction form. RevMan 4.2.8 software was used for data analysis.

RESULTSTwo RCTs and four prospective clinical trials were included. The combined results showed that compare with posterior surgical management, anterior approach in the treatment of thoracolumbar fractures proved the less incidence of complications; better neurologic recovery and corrected kyphosis angle; more complete and reliable decompression of the canal. However, there was not difference between the two groups in the general status outcomes.

CONCLUSIONSTo compare with posterior fixation system, anterior surgical managements in the thoracolumbar spinal trauma might be the optimal choices because the lower rates of complications and loss of corrected kyphosis angle; better neurologic recovery, also. Besides, due to the lack of Evidence-based guidelines for the treatment of thoracolumbar spinal injuries, the results which indicated above need further study.

OBJECTIVETo determine the effect of histamine on N-methyl-D-aspartate (NMDA) induced neuron death and to elucidate its mechanism.

METHODSThe primary cortical cell culture was adopted. Neuron morphology and MTT assay were used to evaluate the drugs effects.

RESULTHistamine at doses of 10(-4) 10(-6) 10(-7) 10(-8) mol/L reversed the neuron death induced by NMDA (50 micromol/L) for 3 h. The protection of histamine peaked at doses of 10(-4) mol/L and 10(-7)mol/L. The effect of histamine of 10(-7) mol/L was reversed only by cimetidine an H(2)receptor antagonist. However, the effect of histamine of 10(-4) mol/L was reversed only by pyrilamine but not cimetidine.

CONCLUSIONHistamine could reduce neuron death induced by NMDA; its protection at a low dose might be mediated by H(2)receptor, and at a high dose by H(1)receptor.

OBJECTIVETo develop a novel method for continuously assessing the spatio-temporal properties of locomotor activity of mice in an open field using a video-tracking system.

METHODSThe locomotor tracks in the open field were recorded by video camera within 22 h, and analyzed by AnalyPower1.1 system that we developed recently. Total distance, distances traveled in different zones and their ratios to total distance; total time,times spent in different zones and their ratios to total time were used as indicators to assess the properties of locomotor activity.

RESULTSIn free and wakeful state, the locomotor activity of mice presented obvious regional and temporal properties. Mice preferred to stay in home base (food and water zones), and frequently visited the peripheral zones but seldom the center zones within 22 h. On the other hand, mice were most active within the first 1 h, and then their activity obviously decreased. After their activity became stable, the mice showed the obvious circadian variation of the activity as they were more active in the night.

CONCLUSIONThe novel method we developed in this study can continuously assess the spatio-temporal properties of locomotor activity quantitatively and objectively.
