BACKGROUND:Conventional therapies for lumbar spondylolisthesis can result in trauma,bleeding and low back pain.With the vigorous development of spinal biomechanics and novel spinal fixation systems,we have more understanding on the reduction and fusion after spondylolisthesis.OBJECTIVE:To observe the clinical effects of transforaminal lumbar interbody fusionvia the quadrant system on lumbar spondylolisthesis and related biomechanical changes.METHODS:A retrospective analysis was done in 23 patients with lumbar spondylolisthesis undergoing transforaminal lumbar interbody fusionviathe quadrant system admitted from June 2012 to September 2013.Oswestry disability index and visual analog scale score were detected at 3 months and 1 year after treatment,as wel as fusion conditions and internal fixation with or without loosening or breakage.RESULTS AND CONCLUSION:Al patients were successfuly treated,with no cerebrospinal fluid leakage and nerve injury.Incisions were healed wel in al cases except one case suffered from incision infection that wascontroled after 10 days of antibiotic treatment.Al the patients were folowed up.The Oswestry disability indexes and visual analog scale scores were significantly improved at 3 months and 1 year after treatment (P ＜0.05),but there was no difference in these two scores at 3 months and 1 year after treatment (P＞0.05).The improvement rates of Oswestry disability index and visual analog scale score were (65.3±14.8)％and (58.2±12.0)％,respectively.These findings indicate that the transforaminal lumbar interbody fusionvia the quadrant system is safe and effective to correct lumbar spondylolisthesis,maintains the biomechanical stability,improves patient's symptoms,reduces the incidence of low back pain and improves the quality of life.

OBJECTIVE: To investigate the effects of Gypsum Fibrosum and Gypsum Fibrosum Preparatum in promoting granulation. METHODS: The wounds of muscle layer were produced in rats by using surgical operation. Two round wounds, with diameter about 1.5 cm, were cut at the depilatory area of two sides of the back of each rat, with an interval of 2 cm, deep to muscle layer, and the thickness of the knife wound of muscle layer was about 0.15 cm. Forty SD rats with the wounds were randomly divided into 4 groups: untreated group, beifuji-treated group, Gypsum Fibrosum-treated group and Gypsum Fibrosum Preparatum-treated group, with 10 rats in each group. Then the wounds were sprinkled with powders of Gypsum Fibrosum and Gypsum Fibrosum Preparatum, or sprayed with beifuji solution, respectively. The healing state of granulation tissues of the wounds was observed at the eighth and fourteenth day respectively. RESULTS: The number of fibroblasts, the number of capillary tubes and the area of capillary tubes in granulation tissue of wounds in the Gypsum Fibrosum Preparatum-treated group were significantly higher than those in the untreated group and Gypsum Fibrosum-treated group (P<0.01). There were no statistical differences between the Gypsum Fibrosum Preparatum-treated group and the beifuji-treated group. However, Gypsum Fibrosum-treated group showed no obvious differences compared to the untreated group (P>0.05). CONCLUSIONS: Gypsum Fibrosum Preparatum can accelerate the formation of collagenoblast and micrangium in wounds, and the proliferation of granulation tissues, thus promoting the skin wounds to healing. The effect of Gypsum Fibrosum is changed after being calcined, and Gypsum Fibrosum Preparatum has obvious effect in promoting granulation.

Objective:To explore whether there will be attentional bias under the condition of fear,disgust and positive emotional arousal. Methods:Totally 96 college students were selected as participants in this study,inclu-ding 60 males and 36 femalesaged 18-22 years. Affective priming videos were adopted to prime participants'emo-tion (dread,disgust,joviality),and then they named the color of the cognitive words (positive words,negative words,neutral words)as quickly and accurately as possible. Reaction time and correctness were recorded. E-prime was adopted to write the experimental program. The reaction time for neutral words was baseline. Results:The aver-age reaction time (RT)of color-naming tasks of negative words were shorter than that of neutral words after fright-ening affective priming[(648 ±118)ms vs. (743 ±124)ms,P<0. 01]. Furthermore,the average RT of color-na-ming tasks of positive words were also shorter than that of neutral after frightening affective priming[(683 ±123) ms vs. (743 ±124)ms,P<0. 05]. The average RT of color-naming tasks of negative words were shorter than that of neutral words after disgusting affective priming[(579 ±86)ms vs. (720 ±101 )ms;P<0. 01 ]. Moreover,the av-erage RT of color-naming tasks of positive words were shorter than that of neutral words after delighted affective priming[(634 ±122)ms vs. (716 ±141)ms;P<0. 01]. Furthermore,the average RT of disgusting priming group-were shorter than the frightening priming grouptowards negative information[(579 ±86)ms vs. (648 ±118)ms,P<0. 05 ]. Conclusion:It suggests that the youth perform more obvious attentional bias towards negative information after disgusting affective priming than the frightening one. Frightening affective priming could evidently induce the attentional bias on positive information.

Objective To study the effects of diacerein and its metabolite rhein on plasma inflammatory cytokine level and expression of perirenal adipose tissue chemerin in type 2 diabetes mellitus (T2DM) rats and its role in regulating glucose and lipid metabolism.Methods We randomly divided 56 SD male rats into 5 groups: normal control group (Group A), T2DM group (Group B), pioglitazone group (Group C), diacerein group (Group D), and pioglitazone+diacerein group (Group E).Group A was fed with ordinary feed whereas the other groups were fed with high-fat diet.At the end of week 8, rats in Groups B, C, D and E were injected intraperitoneally with 30mg/kg of STZ solution to create the model.Those in Group A were injected with the same volume of sterile sodium citrate solution.OGTT examination was taken to screen the model rats at the end of week 10.The successful mode was chosen according to OGTT result.Then Group C was treated with pioglitazone 10mg/(kg·d) orally, Group D with diacerein 50mg/(kg·d), Group E with pioglitazone 10mg/(kg·d)+diacerein 50mg/(kg·d), and Group A and B were given the same volume of normal saline.The intervention lasted 4 weeks.At the end of experiment weeks 10 and 14, FBG, FINS, TC, TG, LDL-C, IL-1β, IL-6, and TNF-α were detected in the fasting rats with free access to water.After blood sample was taken at the end of week 14, all rats were killed and theperirenal adipose tissue was isolated, the expression of chemerin in perirenal adipose tissue was detected by Western blotting.Results At the end of week 10, FBG, FINS, TG, TC, LDL-C, IL-1β, IL-6, and TNF-α were higher in Groups B, C, D and E than in Group A while HDL-C was lower (all P<0.01).At the end of week 14, TC, TG, and LDL-C were lower in Groups C, D and E than in Group B but higher than Group A while HDL-C was lower than in Group A (all P<0.05).Group E had greater changes in glucose and lipid metabolism and inflammatory cytokine level than Groups C and D (P<0.05).Western blotting results showed that the expression of chemerin in perirenal adipose tissue increased higher in Group B than in Groups A, C, D and E (P<0.05).The expression of chemerin were also higher in Groups C and D than in Groups A and E (P<0.05), but there was no significant difference between Groups A and E.Conclusion Diacerein can regulate the metabolism of glucose and lipid, improve insulin resistance by reducing the expression of chemerin and the level of inflammatory cytokines.

OBJECTIVETo observe the effect of the active site of Xiangshia Liujunzitang on behavior, injury of hippocampal neurons and Ca2+ ion in hippocampal synaptic in the depression model mice.

METHODSixty male Kunming mice were randomly divided into 5 group, the control group, the model group and the active site of Xiangshia Liujunzitang groups (400, 600, 800 mg x kg(-1) body weight). The model was established by separation and chronic unpredictable mild stimulation. The increased weight and crossing scores, rearing scores were measured by open-field and sweet water consumption of mice. Cone cell and configuration of neuron in CA1, CA3 region of hippocampus were observed by Nissl. The concentration of Hippocampal synaptic Ca2+ was detected by fluorimetry.

RESULTComparing with the mice of control, the increased weight was slowed (P < 0.001), the scores of rearing and crossing were decreased (P < 0.001), sweet water consumption were decreased, too. Numbers of cone cells in CA3 region of hippocampus were decreased obviously (P < 0.001), and Ca2+ ion in hippocampal synaptic was increased obviously. Comparing with the mice of model, the active site of Xiangshia Liujunzitang could increase the increased weight on the 14 th and 21 st day obviously. The active site of Xiangshia Liujunzitang could increase the scores of crossing obviously (P < 0.05), with no dose-effect relationship. The active site of Xiangshia Liujunzitang (800 mg x kg(-1)) could increase the scores of rearing obviously (P < 0.001); The active site of Xiangshia Liujunzitang (400, 600, 800 mg x kg(-1)) could increase sweet water consumption obviously (P < 0.01, P < 0.01, P < 0.001); The active site of Xiangshia Liujunzitang (600, 800 mg x kg(-1)) could increase numbers of cone cell in CA3 region of hippocampus obviously (P < 0.001); The active site of Xiangshia Liujunzitang (600, 800 mg x kg(-1)) could decreased Ca2+ in hippocampal synaptic with dose-effect relationship (P < 0.01, P < 0.001).

CONCLUSIONThe active site of Xiangshia Liujunzitang can improve all the symptoms of the depression model mice and protect the injury of hippocampal neurons in the depression model mice. The possible mechanism of action is to restrict Ca2+ ion overfreight.

Objective To investigate the epidemiology of BDV infection in Yili horses and Yili donkeys and to analyze phylogenetic source of BDV in Yili area, Xinjiang. Methods We established fluo- rescence quantitative nested RT-PCR to detect BDV p24 segment in peripheral blood mononuclear cells (PBMCs) of 518 Yili horses and 206 Yili donkeys in Yili area, Xinjiang. Positive products were validated by detecting BDV p40 segment and plasmid to preclude the contamination, and were sequenced to analyze the homology of gene sequence, amino acid sequence and phylogenetic tree. Results The positive rates of BDV infection in PBMCs of 518 Yili horses and 206 Yili donkeys were 0.97% and 1.94%, respectively. The results of BDV p40 segment verification were positive in all of the samples of BDV p24 positive. All the samples tested were not contaminated by plasmid. There was a homology of the gene sequence of positive PCR samples with strain He/80. And the gene sequence revealed more than 93% identical to H1766 and strain V. Conclusion Our study suggested BDV natural infection in Yili horses and Yili donkeys. The en- demic BDV had a high degree of identity to strain He/80.

Objective To review the clinical diagnosis and treatment of acute focal renal infarction. Methods Three cases of focal renal infarction were reported and the literature was reviewed.The patients aged from 45 to 63 years with mean age of 54. Two cases had low back pain, 1 case with abdominal pain. Based on clinical history, B-ultrasonography and CT scan, focal renal infarction was diagnosed in 3 patients. There were 2 cases on left kidney and 1 case right. All cases were applied digital subtraction angiography (DSA) and thrombolytic anticoagulant therapy. Results Two cases received DSA and thrombolytic therapy. The other one case received pethidine 50 mg, progesterone 20 mg treatment, the salvia infusion and low molecular heparin 6000 U anticoagulant therapy. All patients had symtoms relieved after 1 d. A week later CT scan, 3 cases of renal infarction were apparently disappeared. Serum creatinine and urea nitrogen were normal. Three patients were followed, mean follow-up time was 1. 5 (0. 5-2) years. Conclusions The diagnosis of acute focal renal infarction mainly depends on B-ultrasound and CT. Early diagnosis and treatment is important for achieving recovery of the compromised renal function. Renal infarction should be suspected in the presence of abdominal pain of sudden onset.
