OBJECTIVETo analyze the relation of plasma D-dimer levels and incidence of deep venous thrombosis after spinal surgery.

METHODSThe clinical data of 63 patients underwent spinal surgery from October 2009 to October 2010 were retrospective analyzed. There were 40 males and 23 females with an average age of 48 years old(21 to 76) in operation. Operation levels of 15 cases were in cervical vertebrae, 4 cases were in thoracic vertebrae,and 44 cases were in lumbar vertebrae. Thirty patients with spinal fracture were caused by trauma and 33 patients without trauma, 11 patients combined with nerve injury. The patients were divided into two groups according to plasma D-dimer levels, more than or equal to 500 microg/L was D-dimer positive group and less than 500 microg/L was D-dimer negative group. Venous blood of all patients early morning with empty stomach were testd on admission, and at 2 h, 1 d, 2 d, 3 d, 4 d, 6 d, 8 d, 10 d, 15 d after operation,respectively.

RESULTSThere was no statistically significant differences in sex, operative segments, implants, operative posture, age, bleed volume, body weight, peroperative D-dimer levels between two groups. After operation, plasma D-dimer of 19 patients were more than or equal to 500 microg/L, with persistent or progressive increasing. Two cases occurred deep venous thrombosis in D-dimer positive group, they respectively were found at 3 days and 8 days after operation. Both of them underwent posterior decompression and internal fixation. However,no deep venous thrombosis was found in D-dimer negative group.

CONCLUSIONPostoperative D-dimer assay can effective predict deep venous thrombosis occurrence. D-dimer level more than or equal to 500 microg/L will be considered as a risk factor for deep venous thrombosis after spinal surgery.

Objective To investigate the expression of macrophage migration inhibition factor (MIF) and cell cycle regulating factor Cyclin D1 in hepatocellular carcinoma tissue and the interaction between MIF and Cyclin D1 in hepatocellular carcinoma cell cycle controlling. Methods Using quantitative real-time PCR and Western blotting to detect mRNA and protein expression of MIF and Cyelin DI in HCC tissues and tumor adjacent tissues. Specific small interfering RNA(siRNA) targeting MIF gene was transfccted at doses of 50 nmol/L and 100 nmoL/L into HCC cell lines of PLC and HepG2 with lipofeetamine 2000 methods to knockdown the expression of M1F gene and to investigare the the interaction between M1F and Cyclin D1. Results MIF and Cyclin D1 protein and mRNA were overexpressed in HCC tumor tissues. The relative expression of MIF,Cyclin D1 protein and mRNA were 0.825±0.13,0.843± 0.104 and 7.31±1.85 folds、4.27±1.05 folds, compared with the tumor adjacent tissues (FMIF= 15.5, P<0.01;FCyclin D1=87.5,P <0.01). In MIF siRNA treated PLC and HepG2 cells, MIF mRNA down regulation 71.2%±7.2%, 87.4%±2.9% ,74.3%±8.9% and 88.4%±4.6% respectively (FPLC = 315.5 ,P < 0.01 ; FHepG2= 201.2 P < 0.01). While MIF protein expression were significandy reduced to 0.33±0.03,0.11±0.02, 0.81±0.08 and 0.36±0.02 in a dose-dependent manner (FPLC= 43.9, P <0.01 ;FHepG2 = 133.4 P <0.01). Cyclin D1 mRNA was significantly down-regnlated in MIF siRNA treated PLC and HepG2 cell lines when compared with control group(P <0.01). In 50 nmol/L and 100 nmol/L groups, Cyclin DI mRNA levels were respectively decreased by 68.2%±3% and 78.1%±1.4% in PLC cell, 65.8%±4.7% and 77.3%±2.6% in HepG2 cell (FPLC= 1569, P < 0.01 ; FHepG2= 480.4, P <0.01). Compared with control groups, Cyclin D1 protein levels significantly reduced to 0.28±0.06、0.15±0.03 and 0.44 ±0.04、0.13±0.02 in the PLC and HepG2 after M IF siRNA treatment(FPLC= 35.5, P < 0.01 ; FHepG2 = 114.7, P < 0.01). Conclusions MIF and Cyclin D1 mRNA and protein were overexpressed in HCC tumor tissues and participated in tumor cell cycle regulation. MIF may up-regnlate the expression of Cyclin DI via ERK signalling and precipitate in carcinogenesis of hepatocellular carcinoma.

A lot of experimental findings have confirmed that: Animal cells acquire a spherical shape just before the division; Under biochemical stimulus of mitotic apparatus aster the cells form a contractile ring in equator plane, and the mother cell divides into two daughter cells; meanwhile the total volume keeps constant. In Zinemanas and Nir's model the reorientation of microfilament and the visco-elasticity of cortex have been took into consideration. In our present work, the effective coefficient m due to biochemical stimulus was incorporated into the model, and the local distribution C was modified to diffuse with the plasma membrane motion. The numerical results showed that the formation of a contractile ring and parameters such as the surface tension in the furrow and internal pressure can be predicted successfully. Compared with Zinemanas and Nir's model, the results of our model are more correspondent with the experimental results. It can be concluded that the effective coefficient m has limited effects on the process control of cytokinesis.

OBJECTIVETo study the therapeutic efficacy of Longqingpian combined with Levofloxacin on Type IIIA prostatitis.

METHODSEighty patients with Type IIIA prostatitis were equally randomized into a Longqingpian group and a Puleanpian group, both treated for 12 weeks. The former were given Longqingpian (once 6 tablets, twice a day) combined with Levofloxacin (once 0.2 g, twice a day) during the first 4 weeks, followed by Longqingpian alone (once 6 tablets, twice a day) for 8 weeks. The latter received Puleanpian (once 4 tablets, 3 times a day) combined with Levofloxacin (once 0.2 g, twice a day) in the initial 4 weeks, followed by Puleanpian alone (once 4 tablets, 3 times a day) for 8 weeks. Before and 4, 8, and 12 weeks after the treatment, all the patients were evaluated by The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and EPS examination.

RESULTSAfter 4-week, 8-week and 12-week treatment, total score of NIH-CPSI, and the score of pain, voiding symptoms and the quality of life dropped significantly in both groups compared with pre-treatment (P < 0.05 or 0.01), so did the leukocyte count in EPS (P < 0.05). Compared with the 4-week treatment, total score of NIH-CPSI, and the score of pain, voiding symptoms and the quality of life were shown to be significantly different (P < 0.05) in the Longqingpian group from the 8-week and 12-week treatment, except the leukocyte count in EPS. However, there was no significant difference between the 8-week and 12-week treatment in any of the indexes (P > 0.05). Longqingpian effected significant differences in the above indexes (P < 0.05), while Puleanpian did not after the treatment (P > 0.05). And the lecithin Amato body analysis revealed no significant changes in EPS after the treatment in either group (P > 0.05).

CONCLUSIONLongqingpian combined with Levofloxacin is highly effective for Type IIIA prostatitis, by relieving pain and voiding symptoms, decreasing the leukocyte count in EPS and improving the life quality of the patients.

OBJECTIVETo explore the risk factors of Parkinson disease (PD), interaction between family history of PD and other risk factors, as well as the relative strength of genetic factors over the vulnerability of PD.

METHODSOne 1:1 matched case-control study including 157 pairs of cases and controls was conducted in Qilu Hospital of Shandong University.

RESULTSConditional logistic regression analysis showed that family history of PD, mental labor, insecticide, alcohol drinking and history of depression all had positive relationship, while smoking had a negative relationship with PD. The AP (AB)s of family history of PD and insecticide, alcohol drinking, history of depression were 55.2%, 34.0%, 41.4% and the RERIs were 8.96, 3.31, 7.85 respectively. The heritability of PD patients' first degree relatives was 36.86% +/- 5.76%, and second degree relatives was 20.66% +/- 6.81%.

CONCLUSIONFamily history of PD had an additive model synergism on PD, coexisting with other risk factors. Genetic factors had a smaller action on PD than environmental factors.

BACKGROUNDPercutaneous radiofrequency thermocoagulation of the trigeminal ganglion (PRTTG) is regarded as the first choice for most patients with trigeminal neuralgia (TN) because of its safety and feasibility. However, neuronavigator-guided PRTTG has been seldom reported. The purpose of this study was to assess the safety and efficacy of neuronavigator-guided PRTTG for the treatment of intractable TN.

METHODSBetween January 2000 and December 2004, 54 patients with intractable TN were enrolled into this study and were randomly divided into two groups. The patients in navigation group (n = 26) underwent PRTTG with frameless neuronavigation, and those in control group (n = 28) received PRTTG without neuronavigation. Three months after the operation, the efficacy, side effects, and complications of the surgery were recorded. The patients in the control group were followed up for 10 to 54 months (mean, 34 +/- 5), and those in the navigation group were followed up for 13 to 58 months (mean, 36 +/- 7). Kaplan-Meier analyses of the pain-free survival curves were used for the censored survival data, and the log-rank test was used to compare survival curves of the two groups.

RESULTSThe immediate complete pain-relief rate of the navigation group was 100%, whereas it was 95% in the control. The proportion of sustained pain-relief rates at 12, 24 and 36 months after the procedure were 85%, 77%, and 62% in the navigation group, and 54%, 40%, and 35% in the control. Recurrences in the control group were more common than that in the navigation group. Annual recurrence rate in the first and second years were 15% and 23% in the navigation group, and 46%, 60% in the control group. No side-effect and complication was noted in the navigation group except minimal facial hypesthesia.

CONCLUSIONNeuronavigator-guided PRTTG is a safe and promising method for treatment of intractable TN with better short- and long-term outcomes and lower complication rate than PRTTG without neuronavigation.

Objective To observe the therapeutic effect of Angelica injection in Parkinsonian rats and explore its possible mechanisms. Methods Rat models of Parkinson disease (PD) were established by 6-OHDA injection into the right substantia nigra pars compacta (SNc) and confirmed by weeldy apomorphine-induced rotation test, and the rats with saline injection served as the saline control group (n=8). After the second apomorphine test, the PD rats received daily intraperitoncal Angelica injection at low (12.5%, n=8) or high dose (25%, n=8), or had only saline injection (PD model group, n=8). Another 8 untreated rats were used as the blank control group. After 4 weeks of treatment, the rats were perfused with paraformaldehyde (4%) and the brains were taken for immunohistochemical detection of TH and CD40 expressions in the SNc using SABC method. Results Compared with the rats in the saline control and low-dose Angelica injection groups, those in the high-dose Angelica injection group showed significantly slowed rotation after a 3-week treatment (P<0.05), with further slowing down at 4 weeks (P<0.01). At the fourth week of treatment with high-dose Angelica injection, a significant increase in the numbers of PH- and CD40-positive neurons was found in the right SNc as compared with those in the low-dose Angelica injection group and the PD model group (P<0.01). No CD40-positive microglia were found in the SNc in the saline control or the blank control groups, and the Angelica-treated groups and the PD model group showed no significant difference in the count of CD40-positive microglia in the SNc. Conclusion Angelica injection produces obvious therapeutic effect in Parkinsonian rats possibly by increasing CD40 expression in the neurons.
