Objective To observe the expression changes of peroxisome proliferator activated receptor γ(PPARγ) following the secondary injuries in rats with spinal cord injury (SCI). Methods Seventy-two male SD rats were equally randomized into control group and SCI group. Real-time fluorescence quantitative polymerase chain reaction (FQ-PCR) was performed to detect the mRNA expression changes of PPARγ on the 1st, 3nd, 7th 14th, 28th and 56th d of SCI. Western blotting wasemployed to detect the protein expression changes of PPARγ Results Compared with those in the control group, the mRNA and protein expressions of PPARγ in the SCI group on the 1st, 3rd, 7th, 14th and 28th d of SCI were significantly increased (P＜0.05), reaching its peak level 14 d after SCI; on the 56th d of SCI, their expression levels in the SCI group were still higher than those in the control group, but no significant differences were noted (P＞0.05). Conclusion The expressions of PPARγare significantly increased following secondary injuries in rats with spinal cord injury, reaching its peak level 14 d after SCI.

Objective Using flowing injection hydride generation atomic fluotometric method(FI-HG- AFM)to detect the whole blood selenium content.Methods A series of standard selenium(1,2,4,6,8.10μg/L) were dectecte by FI-HG-AFM,and the precision and accuracy of the method were observed.The selenium contents of 89 blood samples were detected by FI一HG-AFM and 2,3-diaminonaphthalene fluorometric method(DFM) respectively,and the correlation of two methods Was analyzed.Results The detection limit and recovery rate of FI-HG-AFM were 0.138μg/L and 96.4%,respectively.The relative standard deviation(RSD)was maximized at 1 μg/L(4.406%).The RSD diminished along with the increase of the concentration,and it declined to 0.512%at 10 μg/L.There wag no significant difference(t=1.7878,P>0.05)between the result8 of FI-HG-AFM[(45.9± 14.5)μg/L]and DFM[(47.5 ±13.3)μg/L],and the two methods were in highly positive correlation(r=0.8143,P< 0.01).Conclusions The whole blood selenium content call be rapidly and exactly detected by FI-HG-AFM,and the method are highly consistent with DFM.

OBJECTIVETo evaluate the causes, diagnosis, treatment and prevention of esophagocutaneous fistula in anterior cervical spine surgery.

METHODSThirteen cases with esophagocutaneous fistula in anterior cervical spine surgery were studied.

RESULTSThe causes includes: (1) During the operation, esophagus was oppressed by a clasp for so long time that made a pressure necrosis of the esophagus; (2) Esophagus was injured by loose plates and screws; (3) Loose bone grafts oppressed esophagus; (4) Esophagus was injured by operative appliance in the operation; (5) Esophagus was oppressed by the plate.

DIAGNOSISAfter anterior cervical spine surgery if patients had a high fever, sore throat, swelling incision, and food sediment was found in the incision, esophagocutaneous fistula should be considered. The final diagnosis could be done by esophageal radiography.

TREATMENTFasting cure, nasogastric tube and wound drainage should be used; When the inflammation ended, patients should undergo operation of closure of the esophageal fistula.

CONCLUSIONSThe esophagocutaneous fistula in anterior cervical spine surgery has several causes mentioned above. We should take precautionary measures to avoid the complication, and use appropriate treatment to cure when it happens.

Objective To investigate the myocardial damage in rats fed with corn from Keshan disease area added with bean puree. Methods Male Wistar rats were randomly divided into 3 groups according to their body weights, and fed with corn, corn from Keshan disease area added with bean puree, corn from non-endemic area. The GSH-Px activity of vena cardalis blood was examined in 1 and 3 months, rats were sacrificed after being fed for 6 months to examine the heart changes with HE stain. Results The three groups of GSH-Px activity were different in 1 and 3 months respectively(F=23.60,72.46, all P<0.01); GSH-Px activity was (181.58±22.15), (44.76±28.59)U/L in rats fed with corn, was (195.03±17.66), (30.38±3.35)U/L in those fed with corn added with bean puree from Keshan disease area, lower than the group fed with corn of non-endemic area[(340.90±95.42), (125.17±13.64)U/L, all P < 0.01]. But the difference of GSH-Px activity between simple corn group and corn adding bean puree groups of Keshan disease area was not obvious(P>0.05). Myocardial damage incidence of the three groups was 3/9,1/9,2/7. Difference among three groups did not have statistical significance(χ2=1.33, P> 0.05). Conclusions Only corn from Keshan disease area may induce myocardial damage pathology change. Adding bean puree into corn does not increase damage.

Low birth weight (LBW) and preterm birth (PB) are associated with newborn mortality and diseases in adulthood.We explored factors related to LBW and PB by conducting a population-based case-control study from January 2011 to December 2013 in Wuhan,China.A total of 337 LBW newborn babies,472 PB babies,and 708 babies with normal birth weights and born from term pregnancies were included in this study.Information of newborns and their parents was collected by trained investigators using questionnaires and referring to medical records.Univariate and logistic regression analyses with the stepwise selection method were used to determine the associations of related factors with LBW and PB.Results showed that maternal hypertension (OR=6.78,95％ CI:2.27-20.29,P=0.001),maternal high-risk pregnancy (OR=1.53,95％ CI:1.06-2.21,P=0.022),and maternal fruit intake ≥300 g per day during the first trimester (OR=1.70,95％ CI:1.17-2.45,P=0.005) were associated with LBW.BMI ≥24 kg/m2 of mother prior to delivery (OR=0.48,95％ CI:0.32-0.74,P=0.001) and gestation ≥37 weeks (OR=0.01,95％ CI:0.00-0.02,P＜0.034) were protective factors for LBW.Maternal hypertension (OR=3.36,95％ CI:1.26-8.98,P=0.016),maternal high-risk pregnancy (OR=4.38,95％ CI:3.26-5.88,P＜0.001),maternal meal intake of only twice per day (OR=1.88,95％ CI:1.10-3.20,P=0.021),and mother liking food with lots of aginomoto and salt (OR=1.60,95％ CI:1.02-2.51,P=0.040) were risk factors for PB.BMI ≥24 kg/m2 of mother prior to delivery (OR=0.66,95％ CI:0.47-0.93,P=0.018),distance of house from road ≥36 meters (OR=0.72,95％ CI:0.53-0.97,P=0.028),and living in rural area (OR=0.60,95％ CI:0.37-0.99,P=0.047) were protective factors for PB.Our study demonstrated some risk factors and protective factors for LBW and PB,and provided valuable information for the prevention of the conditions among newborns.

OBJECTIVETo discuss surgical approaches of ossification of the posterior longitudinal ligament (OPLL) of cervical spine.

METHODSBetween June 2005 to July 2010, 36 patients with OPLL of cervical spine were reoperated. There were 23 male, 13 female, age from 39 to 72 years (mean 57 years). The time of the first operation to the reoperation were 4 months to 24 years, an average of 3.9 years. Among 20 patients underwent anterior corpectomy and fusion (ACD) at first operation, 14 cases combined stenosis of cervical spinal canal, 10 cases were insufficient decompression of OPLL, 5 cases injured of cervical spinal cord during the first operation, 1 case was adjacent disc herniation. Among 14 cases underwent expensive open-door laminoplasty (ELAP) at first operation, 6 cases were insufficient decompression of OPLL, 4 cases were inadequate decompressed segment, 2 cases were cervical segmental kyphosis, 2 cases were progression of OPLL combined with disc herniation. Among 2 cases underwent combined approach at first operation, 1 case was insufficient decompression of OPLL, the other was adjacent disc herniation. Their pre- and post-operative X-ray, CT and MRI were analyzed. The complications of reoperation were recorded.

RESULTThere were 30 patients followed-up, with a period of 1.5 - 4.0 years, average 1.8 years. With 36 patients, none had deterioration, 2 patients had no recovery post-reoperation, 34 patients had 31.2% Japanese Orthopedic Association score improve rate. Among 22 cases underwent ELAP at second operation, 3 cases had postoperative segmental palsy. Among 14 cases underwent ACD at second operation, 3 cases had intraoperative dural defects.

CONCLUSIONSurgical strategy for OPLL of cervical spine should consider the type of OPLL and stenosis of cervical spinal canal.

OBJECTIVETo detect the expression level of asparagine synthetase (ASNS) in patients with relapsed or refractory extranodal NK/T cell lymphoma and explore its clinical significance.

METHODSTen patients with relapsed or refractory extranodal NK/T cell lymphoma admitted in our department from January, 2013 to January, 2016 were analyzed. The diagnoses were confirmed by pathological and immunohistochemical examination following failed chemotherapies in all cases. Branched DNA-liquidchip technique (bDNA-LCT) was used for detecting ASNS mRNA expression in paraffin-embedded tissue sections in the 10 cases of relapsed or refractory extranodal NK/T cell lymphoma and in 5 cases of chronic rhinitis. The correlations were analyzed between ASNS expression and the clinicopathological features and outcomes of the patients with failed chemotherapy regimens containing asparaginasum.

RESULTSSix out of the 10 patients with relapsed or refractory extranodal NK/T cell lymphoma died due to diseaseprogression. The expression level of ASNS was significantly higher in the lymphoma tissues than in tissue specimens of chronic rhinitis (P<0.05). The expression level of ASNS was associated with the International Prognostic Index (P=0.023) in patients with relapsed or refractory extranodal NK/T cell lymphoma, and Kaplan-Meier curve showed that a high ASNS expression was correlated with a reduced overall survival and progression-free survival of the patients.

CONCLUSIONAsparaginasum-based chemotherapy regimens are recommended for treatment of relapsed or refractory extranodal NK/T cell lymphoma with low ASNS expressions.

OBJECTIVETo evaluate anterior cervical plating in short-level anterior discectomy and autograft bone fusion.

METHODSEighty-one patients who underwent one- and two-level anterior cervical discectomy and fusion were randomized to 2 groups, with or without instrumentation. Among them, 55 patients were followed up. The mean follow-up time was (22 +/- 7) months. Fusion rate, disc height and cervical lordotic alignment were assessed by radiographs.

RESULTSThe improving rates were 68% in non-instrumented group and 58% in instrumented group, respectively (P > 0.05). The fusion rate was 93% in the non-instrumented group and 100% in the later one. The disc height was decreased (0.7 +/- 1.0) mm in the former group and increased (1.2 +/- 0.6) mm in the later one (P < 0.01). Although the postoperative cervical lordotic alignment was maintained better in instrumented group, the difference was not significant.

CONCLUSIONAnterior cervical plating can make good influence on the result of anterior cervical discectomy and fusion in some degree.

OBJECTIVETo explore the relationship between kruppel-like factor (KLF)6 gene and the development or progression of hepatocellular carcinoma (HCC).

METHODSReverse-transcription polymerase chain reaction (RT-PCR) was used to examine the expression of KLF6 mRNA in normal liver tissue and primary hepatocellular carcinoma, and single strand conformation polymorphism (SSCP), DNA sequencing were used to detect the point mutation of KLF6 in primary hepatocellular carcinoma.

RESULTSAn amplified fragment of 427 bp DNA was detected in 31 (97%) of 32 adjacent noncancerous tissue and normal liver tissue, and in 23 (85%) of 27 HCCs. There was no significant difference in the levels of KLF6 mRNA between normal liver and liver tumors (chi(2) = 2.58, P > 0.05). For the 27 HCCs, six SSCP-positive bands (22%) were detected. Among them, three of 5 (3/5) tumor samples showing loss of heterozygosity (LOH) of KLF6 had mutations in the retained KLF6 allele.

CONCLUSIONWe showed that LOH was detected in 5 (36%) HCCs obtained from 14 informative cases, and three of 5 tumor samples showing LOH of KLF6 had mutations in the retained KLF6 allele. Two inactivating events had occurred; thus, as defined by Knudson's "two-hit model", 16 KLF6 appears to be a tumor suppressor gene.
