Objective To explore the clinical outcome of atlantoaxial pedicle screw instrument in treatment of extension-type odontoid fracture combined with aflantoaxial subluxation. Methods From December 2002 to December 2006, seven patients with extension-type odontoid fracture combined with at-lantoaxial subluxation were reduced and fixed with atlantoaxial pedicle screw instrument of Vertex system under general anesthesia. There were five males and two females, at mean age of 39.2 years (range 21-59 years). All odontoid fractures were fresh type Aderson Ⅱ. JOA scores of spinal core function was 8.6-14.9 (average 10.7) preoperatively. The X-ray examination, CT scanning and skull traction were performed in all patients preoperatively. Results There found no severe complications such as injuries of vertebral artery, nerve root and spinal cord postoperatively. All patients obtained complete reduction and healing of the fracture and dislocation. The mean off-bed time was four days (3-6 days) after opera-tion. A follow-up for 12-36 months (average 22 months) in all patients showed that the clinical symptom was improved significantly six months postoperatively and that all screws were in proper position verified by X-ray and CT scanning. All patients obtained solid bony union on radiographs, with no loosing or breakage of instrument. The postoperative JOA scores was 13.5-16.9 (average 15.8). Conclusions Allantoaxial pedicle screw fixation has advantages of intraoperative reduction, reliable fixation and high fusion rate and can be used as an effective method for extension-type odontoid fracture combined with at-lantoaxial subluxation.

Objective To investigate the changes of fecal short-chain fatty acids (SCFA) and bile acid levels in patients with colon cancer.Methods Totally 189 patients with colon cancer (CC group),201 patients with adenomatous polyp (AP group),and 512 healthy patients (control group) who were confirmed by endoscopy were included in this study.The fecal SCFA and bile acid levels were measured by enzyme linked immunosorbent assay.Results The total bile acids,primary bile acids,and secondary bile acids were not significantly different among these three groups (P ＞ 0.05).The chenodeoxycholate level in the CC group [0.338 (0.101,0.416) mg/g] was significandy higher than that in AP group [0.241 (0.108,0.375) mg/g] and control group [0.248 (0.110,0.371) mg/g] (P=0.025,P=0.023),but was not significantly different between the AP groupand the control group (P ＞ 0.05).The deoxycholic acid level in CC group [0.375 (0.136,0.503) mg/g] and AP group [0.369 (0.113,0.494) mg/g] were significandy higher than that in control group [0.277 (0.115,0.412) mg/g] (P=0.026,P=0.024),and the difference between CC group and AP group was not statistically significant (P ＞ 0.05).The level of lithocholic acid in CC group [0.386 (0.147,0.507) mg/g] was significantly higher than those in the AP group [0.103 (0.012,0.238) mg/g] and control group [0.239 (0.081,0.405) rng/g] (P=0.011,P=0.027); also,its level in AP group was significantly lower than that in the control group (P =0.022).The levels of total short-chain fatty acids,acetic acid,propionic acid,and isovaleric acid were not significantly different among the control group,AP group,and CC group (P＞0.05).The levels of butyrate [0.105 (0.059,0.198) mg/g,0.090 (0.050,0.183) mg/g],isobutyl acid [0.036 (0.024,0.046) mg/g,0.025 (0.020,0.034) mg/g] in CC group and AP group were significantly higher than in the control group [0.081 (0.051,0.107) mg/g,0.021 (0.016,0.029) mg/g] (butyrate:P=0.026,P=0021; isobutyl acid:P=0.025,P=0.019),and the difference between CC group and AP group was statistically significant (butyrate:P =0.031; isobutyl acid:P =0.024).Conclusions Fetal chenodeoxycholic acid,lithocholic acid,butyric acid,and isobutyric acid may play a role in the developmem of colon cancer,while deoxycholic acid may also be implicated in both colon cancer and colon adenomas.No association is found between other SCFA and bile acids and colorectal cancer/adenoma.

Objective:To study the effects of hydrogen molecule on the formation of pelvic and abdominal adhesions in dogs, and to explore its possible mechanism.Methods:The Beagle pelvic and abdominal adhesion model was constructed. 15 Beagle dogs were randomly divided into 3 groups: model control group, hydrogen treatment group and blank control group. The Phillips adhesion score was used to evalute the morphological adhesion degree. The morphology of intestinal, uterus and ovarian tissues was evaluated by hematoxylin-eosin (HE) staining. The inflammation biomarkers and oxygen free radical index were detected before modeling and on the 1st, 4th, 7th and 14th day after modeling. C-reactive protein (CRP), tumor necrosis factors-α (TNF-α) and interleukin(IL)-6 content in serum were detected by enzyme-linked immunosorbent assay (ELISA) kit; hydroxylamine method was used to detect the serum superoxide dismutase (SOD); thiobarbituric acid (TBA) colorimetric method was used to measure malondialdehyde concentration.Results:The Phillips adhesion score of the model control group was significantly higher than that of the blank control group ( P<0.05). The Phillips adhesion score of the hydrogen treatment group was significantly lower than that of the model control group ( P<0.05). In the hydrogen treatment group, the thickening of serous layer on the surface of intestine, uterus and ovary and the degree of inflammatory infiltration were lower than those in the model control group.The inflammatory indexes (leukocyte count, CRP, IL-6, TNF-α) and malondialdehyde level in the model control group were higher than those in the blank control group on the first day after modeling, and the superoxide dismutase (SOD) level was lower than that in the blank control group (all P<0.05); the inflammatory indexes and malondialdehyde level in the hy-drogen treatment group were lower than those in the model control group on the first day after modeling ( P<0.05), and the SOD level was higher than that in the model control group ( P<0.05). Conclusions:Hydrogen molecule can effectively inhibit the formation of pelvic adhesion in Beagle dogs, and its possible mechanism is to neutralize oxygen free radicals and reduce inflammatory reaction.

Objective: To explore the safety and effectiveness of 3D reconstruction in thoracoscopic posterior basal segmentectomy (S10). Methods: Between March 2018 to September 2018, 14 patients underwent thoracoscopic anatomical resection of the posterior basal segment of the lung (S10). Results: Of the 14 patients, including 5 males and 9 females, age (52.2±5.3)years, size (1.1±0.6)cm, 6 left S10 and 8 right S10. The number of pathological type of microinvasive adenocarcinoma, benign nodule, and metastatic carcinoma was 12, 1, and 1 cases. The average preoperative planning time was (44.9±5.7)min, and the average operation time was (134.8±26.3)min. The blood loss was (25.5±4.1)ml, with (8.1±2.7) lymphadenectomy, no positive metastasis. The coincidence rate of 3D reconstruction and intraoperative anastomosis in the tumor location, B10, A10, and V10 were 100%(14/14), 100%(14/14), 93%(13/14) and 71%(10/14). The median duration of chest tube insertion was (2.3±2.1)day. The incidence of postoperative complications was 21%(3/14), including 7%(1/14) of air leakage, 7%(1/14) of arrhythmia, 14%(2/14) of pulmonary infection, and 14%(2/14) of operation. All the cutting edge was >2 cm. There was no perioperative death, no conversion to thoracotomy or lobectomy. The mean follow-up time was (8.1±2.2)months. There were no recurrence, metastasis or death in the 14 patients. One patient had chronic cough and no hemoptysis. Conclusions Preoperative 3D reconstruction make the anatomic thoracoscopic posterior basal segmentectomy (S10) safer and more effective.

OBJECTIVETo investigate the role of hepatocyte apoptosis and mitochondrial permeability transition pore (MPTP) opening in the pathogenesis of nonalcoholic fatty liver disease (NAFLD).

METHODSThirty male SD rats were randomized into normal diet group and high-fat diet group. At 4, 8 and 12 week of feeding. The hepatocyte apoptosis index (AI) was measured using flow cytometry, and MPTP opening was evaluated with ultraviolet spectrophotometry. Immunohistochemistry was employed to detect hepatic expressions of Bcl-2 and Bax, and Western blotting was used to detect Bax protein expression changes.

RESULTSHigh-fat feeding resulted in significantly increased hepatocyte AI at 4-12 weeks and gradually increased MPTP opening. In the high-fat diet group, hepatic Bcl-2 expression was detected but the positive cell number remained stable, whereas Bax-positive cell number increased steadily with time with progressively increased intensity of Bax protein expression, resulting in gradually decreased Bcl-2/Bax ratio.

CONCLUSIONHepatocyte apoptosis occurs in the rat model of NAFLD in close correlation with mitochondrial damage. Increased MPTP opening as the result of increased Bax expression and aberrant Bcl-2/Bax ratio is an important mechanism of hepatocyte mitochondrial damage in NAFLD.

OBJECTIVE:To provide references for clinicians in the choice of antihypertensive drugs.METHODS:The antihypertensive efficacy 6 classes(or 15 kinds) of antihypertensive drugs in a monotherapy in the treatment of 370 patients with essential hypertension(EH) were compared.RESULTS:The blood pressure was effectively lowered by all of the antihypertensive drugs except doxazosin,and doxazosin and torasemide showed inferior efficacy in the reduction of diastolic blood pressure(DBP).CONCLUSION:Calcium antagonists with prolonged action,angiotensin converting enzyme inhibitor(ACEI),angiotens-in receptor antagonist,and the monotherapy of Terazosin or Indapamide can all effectively bring down the blood pressure.It is suggested that low-dose doxazosin and torasemide should not be used alone in treating essential hypertension.

Objective:To investigate the independent predictors of the long-term clinical outcomes in patients with branch atheromatous disease (BAD) in lenticulostriate artery (LSA) territory.Methods:Patients with LSA-BAD admitted to the Department of Neurology, Zhongnan Hospital of Wuhan University from January 1, 2016 to June 1, 2019 were enrolled retrospectively. Their demography, vascular risk factor, and baseline clinical data were collected. The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the severity of stroke. The clinical outcomes were evaluated by the modified Rankin Scale at 6 months. 0-2 was defined as good outcome, and >2 was defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent influencing factors of clinical outcomes in patients with LSA-BAD. Results:A total of 81 patients with LSA-BAD were enrolled. Their age 59.20±11.75 years (range, 39-81 years), 53 were male (65.4%), and median baseline NIHSS score was 1.0 (interquartile range, 0-4.0). Forty-one patients (50.6%) received intravenous thrombolysis. At 6-month follow-up after the onset, 63 patients (77.8%) had a good outcome, and 18 (22.2%) had a poor outcome. The baseline NIHSS score of the poor outcome group was significantly higher than that of the good outcome group (6.5 [0-9.0] vs. 1.0 [0-3.0]; Z=2.395, P=0.017), while the proportion of mild stroke (61.6% vs. 98.4%; χ2=17.595, P<0.001) and patients receiving intravenous thrombolysis (38.9% vs. 54.0%; χ2=4.450, P=0.035) were significantly lower than those of the good outcome group. Multivariate logistic regression analysis showed that after adjusting for other confounding factors, venous thrombolysis was independently correlated with the good outcome (odds ratio 0.099, 95% confidence interval 0.011-0.924; P=0.042), while the high baseline NIHSS score was independently associated with the poor outcome (odds ratio 1.736, 95% confidence interval 1.262-2.388; P=0.001). Conclusion:Intravenous thrombolysis is helpful to improve the outcomes of patients with LSA-BAD, and a higher baseline NIHSS score is an independent predictor of the poor outcome.
