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 efficacy and safety of domestic oseltamivir in patients with influenza. Methods A randomized, single-blinded, controlled clinical trial was performed.Patients in the study group received domestic oseltamivir, while the patients in control group received foreign oseltamivir. The doses were both 75 mg every time, twice a day. The treatment durations in both groups were 5 days. Chi square test was performed to compare baseline characteristics and the difference of side effects. Paired t test was used to compare the efficacy. Results Two hundred and nine patients were enrolled in this study (98 cases in study group. 111 cases in control group). The trend in body temperature change was similar in the two groups (t = 0. 061, P>0. 05). The score of symptom severity decreased more quickly in patients treated with foreign oseltamivir compared to those treated with domestic oseltamivir during the period from 24 h to 48 h. However, the difference between the two groups diminished gradually and was not statistically significant at 72 h (t=0. 875,P>0. 05). The safety of the domestic and foreign oseltamivir were comparable(X2 = 0. 197,P>0. 05). Conclusion The domestic oseltamivir is as effective and safe as the foreign oseltamivir.

This study is to explore new lead compounds by inhibition of Pin1 for anticancer therapy using temperature sensitive mutants. As Pin1 is conserved from yeast to human, we established a high-throughput screening method for Pin1 inhibitors, which employed yeast assay. This method led to the identification of one potent hits, 8-11. In vitro, 8-11 inhibited purified Pin1 enzyme activity with IC50 of (10.40 +/- 1.68) micromol x L(-1), induced G1 phase arrest and apoptosis, showed inhibitory effects on a series of cancer cell proliferation, reduced Cyclin D1 expression, was defined as reciprocally matched for protein-ligand complex in virtual docking analysis and reduced cell migration ability. In vivo, we could observe reduction of tumor volume after treatment with 8-11 in xenograft mice compared with vehicle DMSO treatment. Altogether, these results provide for the first time the involvement of 8-11 in the anticancer activity against Pin1.

Primary mitochondrial disease is the most common inborn error of metabolism and is highly heterogeneous in terms of clinical manifestations and inheritance pattern. It has high mortality and disability rates. Multiple systems are often involved in this disease, and it is necessary to perform comprehensive evaluation and multidisciplinary management. The Mitochondrial Medicine Society issued the standard for the management of patients with primary mitochondrial disease: consensus statements from the Mitochondrial Medicine Society in 2017. The statements provided recommendations based on such consensus to guide the management and care of patients. This article interprets and summarizes the screening of organs and systems commonly involved in primary mitochondrial disease and the management of patients according to the consensus.

OBJECTIVETo investigate the effect and mechanism (a selective cyclooxygenase-2 inhibitor) on invasive ability of human nasopharyngeal carcinoma (NPC) line CNE-2Z.
METHODSThe proliferation of NPC cells was examined by MTT assay. The invasive and migrating ability of NPC cells was detected with transwell chamber. E-cadherin protein expression was detected by immunocytochemistry and the expressions of Cox-2 and E-cadherin mRNA were analyzed by reverse transcription-polymerase chain reaction (RT-PCR).
RESULTSMTT showed that celecoxib inhibited CNE-2Z proliferation in dose-dependent manner, the survival rate of cells treated with 25, 50, 100 µmol/L celecoxib (x(-) ± s) for 24 h was (94.75 ± 1.34)%, (91.77 ± 2.70)%, (64.54 ± 1.20)%, respectively, and the survival rate of cells treated for 48 h was (88.41 ± 1.28)%, (78.84 ± 1.56)%, (52.46 ± 2.25)%, respectively, the concentration of 50% inhibition concentration of a substance (IC50) was 100 µmol/L, the difference was statistically significant between different concentration groups in the same time-point (respectively, F were 462.204 and 1328.306, P < 0.01). Treated with different concentrations of celecoxib (0, 25, 50 µmol/L) for 24, the cell numbers (x(-) ± s) through PVPF by tumor invasion assay were (263.7 ± 13.5), (185.3 ± 8.7) and (144.0 ± 8.2), the difference was statistically significant between the experimental and control group (F = 102.089, P < 0.01). Immunocytochemistry showed that celecoxib significantly induced the increase of E-cadherin protein expression, also with a dose-dependence in 0 µmol/L, 25 µmol/L, 50 µmol/L group was (21.7 ± 2.6), (28.7 ± 2.4), (40.3 ± 1.3), and 50 µmol/L group increased significantly (F = 78.637, P < 0.01). RT-PCR showed that celecoxib reduced the expression of Cox-2 mRNA expression in 25, 50 µmol/L group decreased significantly compared with the control group (respectively, t were 23.950 and 36.651, P < 0.01), but it enhanced the expression of E-cadherin mRNA expression in 25, 50 µmol/L group was significantly higher (respectively, t were 35.829 and 81.497, P < 0.01).
CONCLUSIONCelecoxib can inhibits the invasive ability of NPC cell line CNE-2Z, which possibly relates with the upregulated expression of E-cadherin.

Objective: To explore whether acupuncture can improve sleep disturbance, cognitive impairment and emotional disorders caused by sleep deprivation, and its association with the attenuation of oxidative stress injury in prefrontal cortex. Methods: Fifty-two male Sprague-Dawley rats were randomly divided into a control group (n=10), a model group (n=14), a manual acupuncture (MA) group (n=14), and a sham-MA group (n=14). All the groups were established as sleep deprivation models via the modified multiple platform method, except for the control group. Rats in both the MA group and the sham-MA group received corresponding intervention, respectively. After modeling and intervention, the four groups received three behavioral tests, namely sleep monitoring, by comprehensive lab animal monitoring system (CLAMS), Morris water maze (MWM) test and open-field test (OFT), followed by oxygen free radical level test and Western blot (WB) detection for the expression levels of Bax and Bcl-2. Results: The MA group derived more sleep time within 24 h than either the model group or the sham-MA group (both P<0.05). On MWM orientation navigation test day 1, there were no significant differences in escape latency among the control, MA and sham-MA groups (P>0.05), and the escape latency was significantly shorter in these three groups than that in the model group (all P<0.05). On test day 4, the escape latency was markedly shorter in the MA group than that in either the model group or the sham-MA group (both P<0.05); meanwhile, the MA group showed significantly better performance compared with these two groups in space probe test (both P<0.05). In OFT, compared with the control group, there was a significant decline in the horizontal movement score in the other three groups (all P<0.05), and the decrease was more significant in the model group and the sham-MA group than that in the MA group (both P<0.05). The superoxide dismutase (SOD) content was markedly higher and the malondialdehyde (MDA) content was markedly lower in the MA group than those in the model group and the sham-MA group (all P<0.05). Compared with the model group and the sham-MA group, the expression of Bax was significantly lower and the expression of Bcl-2 was significantly higher in the MA group (all P<0.05). Conclusion: MA therapy can lengthen the sleep time in sleep-deprived rats and improve learning and memory impairments induced by sleep deprivation, and the underlying mechanism may be associated with the enhancement of antioxidant capacity in the prefrontal cortex and the inhibition of hippocampal neuronal apoptosis.
