Objective:To evaluate the effects of stellate ganglion block (SGB) on the activation of M1 microglia during cerebral ischemia-reperfusion (I/R) in rats.Methods:Fifty-four SPF healthy male Sprague-Dawley rats, aged 8-10 weeks, weighing 240-270 g, were divided into 3 groups ( n=18 each) using a random number table method: sham operation group (group Sham), cerebral I/R group (group IR) and SGB group.Blood vessels were only exposed, without occlusion in group Sham.Cerebral I/R was induced by occlusion of the middle cerebral artery for 90 min followed by reperfusion in group IR.Cervical sympathetic trunk transaction was performed to induce left SGB immediately after onset of reperfusion in group SGB.Blood samples were collected from the apex of the heart at 6, 12 and 24 h of reperfusion for determination of the concentrations of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β in the serum (using enzyme-linked immunosorbent assay). The animals were sacrificed after the neurological function was evaluated at 24 of reperfusion, and brain tissues were removed for microscopic examination of the pathological changes in cortex, for determination of percentage of cerebral infarct size (by TTC staining), for assessment of cell apoptosis and apoptosis rate in cortex (by TUNEL), and for determination of the expression of microglial biomarker Iba-1 and activated M1 microglia biomarker CD68 (by Western blot). Results:Compared with group Sham, the neurological function score, percentage cerebral infarct size, apoptosis rate in cortex, concentrations of TNF-α, IL-6 and IL-1β in the serum, and the expression of Iba-1 and CD68 were significantly increased in IR and SGB groups ( P<0.05). Compared with group IR, the neurological function score, percentage cerebral infarct size, apoptosis rate in cortex, concentrations of TNF-α, IL-6 and IL-1β in the serum, and the expression of Iba-1 and CD68 were significantly decreased in group SGB ( P<0.05), and the pathological changes of brain tissues were significantly attenuated in group SGB. Conclusion:The mechanism by which SGB reduces cerebral I/R injury is related to inhibiting activation of M1 microglia in rats.

Objective To detect the serum IgG4 and autoantibodies levels in patients with orbital disease of unknown reasons,and to investigate their values in patients with orbital disease.Methods A total of 366 patients with orbital disease of unknown reasons recruited in the Department of Ophthalmology,Beijing Tongren Hospital Affiliated to Capital Medical University from October 2013 to October 2016 were retrospectively enrolled as orbital disease group,and 266 patients with autoimmune disease in the same period from the Department of Rheumatology of the hospital were selected as controls.The serum IgG4 was detected by rate scattering method,antinuclear antibody(ANA),anti-double-stranded DNA(dsDNA)antibody as well as anti-extractable nuclear antigen(ENA)antibody were measured by indirect immunofluorescence assay,and anti-neutrophil cytoplasmic antibody(ANCA)was detected by enzyme linked immunosorbent assay,all of which were compared between the orbital disease patients and the controls using chi-square test.Results The positive rate of the serum IgG4 in the patients with orbital disease was 36.1％(132/366),obviously higher than that in the controls(27.1％,72/266),the difference being statistically significant(x2 =5.705,P=0.017).And the positive rate of serum IgG4≥1 350 mg/L(29.0％,106/366)in the patients with orbital disease was higher than that in the controls(21.8％,58/266; x2 =4.107,P=0.043).The positive rate of ANA in the patients with orbital disease was 17.8％(65/366),obviously lower than that in the controls(28.6％,76/266),the difference also being statistically significant(x2 =10.389,P=0.001).The positive rate of anti-ENA antibody in the patients with orbital disease was 4.6％(17/366),also obviously lower that that in the controls(9.0％,24/266),with statistically significant difference as well(x2 =4.866,P=0.027).No anti-dsDNA antibody was detected in the patients with orbital disease.Only three patients with orbital disease(0.8％,3/366)were found ANCA positive,and no statistically significant difference was found in comparison with the controls(3.0％,8/266; x2 =3.127,P=0.077).Conclusions Elevated IgG4 level was commonly seen in the patients with orbital disease,where as autoantibodies were negative in the most of the patients,indicating that IgG4 might correlate with orbital disease,and part of orbital disease may belong to the IgG4-related orbital disease.

Objective:To study the colonization ability of Streptococcus oligofermentans (S.oligofer-mentan)in the condition of high sucrose in oral cavity of rats.Methods:In this study,48 SPF-SD rats aged 21 days were selected.From 24th to 27th days,the rats were fed with water of antibiotic and fed with high glucose diet continuously.On the 28th day,the rats were divided into four groups randomly,12 rats per group.From the 28th day to 30th day,the first group (SMgroup)was inoculated with S.mutans,the second group (SO group)with S.oligofermentan,the third group (SO+SM group)with mixture of S. mutans and S.oligofermentan,the control group not with any bacteria.On the next day and the 10th day after inoculation of bacteria,the samples of dental plaque of the rats were acquired by scrubbing occlu-sal,buccal and lingual surfaces of bilateral mandibular molars with sterile swabs.The samples of SM group were inoculated on MSB and BHIS,of SO group on MSAE,of SO+SMgroup on MSB,MSAE and BHIS,of the control group on MSB and MSAE.S.mutans were screened and calculated on MSB,the suspected colonies of S.oligofermentan were screened and identified by the analysis of 16S rDNA.Re-sults:On the next day,the detection rate of S.oligofermentan was 33.3% (4/12)in the group of SO;in the group of SO+SM,the detection rate of S.oligofermentan was 0,the detection rate of S.mutans 100.00%,and the proportion of S.mutans 14.70%±4.53%;in the group of SM,the detection rate of S.mutans was 100.00%,the proportion of S.mutans 12.42%±4.27%.On the 10th day,in the group of SO,the detection rate of S.oligofermentan was 0;in the group of SO+SM,the detection rate of S.oligofermentan was 0,the detection rate of S.mutans 100.00%,and the proportion of S.mutans 15.78%±5.10%;in the group of SM,the detection rate of S.mutans was 100.00%,and the propor-tion of S.mutans 17.08%±5.75%.Conclusion:In the condition of the experiment where high glucose was maintained in the oral cavity in rats,S.oligofermentan appeared transiently and couldn’t colonize in the rats.

Objective To investigate the tumor diameter on the prognosis of patients with advanced esophageal squamous cell carcinoma(ESCC) after Ivor-Lewis surgical resection.Methods The clinical data of 254 patients with advanced ESCC who received Ivor-Lewis surgical resection at the Affiliated Hospital of Tianjin Medical University from January 2005 to December 2008 were retrospectively analyzed.All the patients were followed up via outpatient examination,telephone interview and correspondence till December 2013.Survival curve was drawn by the Kaplan-Meier method,and survival rate was analyzed using the Log-rank test.Receiver-operating-characteristic (ROC) curve analysis was used to determine the appropriate cutoff value of tumor size.Univariate and multivariate analysis were done using the chi-square test and COX regression model.Results Of 254 patients,223 patients were followed up for a median time of 30 months (range,3-108 months) with a follow-up rate of 87.80％ (223/254).The median total survival time was 27 months,and the 1,3,5-year overall survival rates were 72.7％,42.2％ and 31.3％,respectively.ROC analysis showed that the appropriate cutoff value of tumor diameter was 3.5 cm.The median survival time and 5-year survival rate were 36 months and 39.3％ in patients with tumor diameter ≤ 3.5 cm and 18 months and 25.4％ in patients with tumor diameter ＞ 3.5 cm,respectively,with a significant difference (x2 =9.494,P ＜ 0.05).The results of univariate analysis showed that the age,tumor diameter,depth of tumor invasion,lymph node metastasis and postoperative adjuvant therapy were related factors affecting the prognosis of patients with advanced ESCC after Ivor-Lewis surgical resection (x2=4.459,9.494,6.993,10.382,5.507,P ＜ 0.05).The results of multivariate analysis showed that tumor diameter ＞ 3.5 cm,lymph node metastasis and no postoperative adjuvant therapy were the independent factors affecting the prognosis of patients with advanced ESCC after Ivor-Lewis surgical resection (HR =1.631,1.681,0.677,95％ confidence interval:1.151-2.312,1.198-2.358,0.487-0.942,P ＜ 0.05).Of 159 patients without postoperative lymph node metastasis,median survival time and 5-year accumulated survival rate were 49 months and 46.4％ in patients with tumor diameter ≤ 3.5 cm and 23 months and 32.0％ in patients with tumor diameter ＞ 3.5 cm,respectively,with a significant difference (x2 =6.412,P ＜ 0.05).Conclusions The tumor diameter ＞ 3.5 cm,lymph node metastasis and no postoperative adjuvant therapy are the independent factors affecting the prognosis of patients with advanced ESCC after Ivor-Lewis surgical resection,meanwhile there is an assessed value of tumor diameter on the prognosis of patients without lymph node metastasis.

BACKGROUND:In recent years, endoplasmic reticulum stress-caused apoptosis plays a crucial role in ischemia impairment and has become the hotspot of studies addressing myocardial ischemia/reperfusion (I/R) injury. The lower limb ischemic preconditioning (LIP) has the obvious protective effect on the immature myocardium, but until now, no study reports whether LIP effects on endoplasmic reticulum stress apoptosis in immature myocardial cells. OBJECTIVE:To investigate the effect of LIP on endoplasmic reticulum stress and apoptosis.
METHODS:Langendorff-perfused isolated rabbit hearts were used in this study. Twenty-four immature rabbits were randomized into three groups. Control group:Isolated rabbit heart was only perfused with Krebs-Henseleit for 180 minutes. I/R group:Isolated rabbit heart was perfused 20 minutes, and then ischemia for 60 minutes fol owed by reperfusion 100 minutes. LIP group:Limbs were repeatedly obstructed 5 minutes and relaxed 5 minutes for three times, to establish Langendorff models, and then repeated the method of ischemia/reperfusion in I/R group. The myocardial apoptosis was assayed with TUNEL method. The expression of glucose-regulated protein 78, Bcl-2, Bax and Fas was detected with western blot analysis.
RESULTS AND CONCLUSION:Compared with I/R group, apoptosis rate was significantly lower, the expression of Bcl-2 was significantly higher, and the expression of glucose-regulated protein 78, Bax and Fas was significantly lower in LIP group. This study demonstrated that LIP regulates myocardial cellapoptosis through reducing the expression of endopasmic reticulum stress GRP78, Bax and Fas and increasing the expression of Bcl-2.

Objective To screen the risk factors of liver metastasis in patients with postoperative colorectal cancer and to set up a mathematic model.Methods One hundred and sixty-eight patients received radical surgery were retrospectively analyzed.Logistics model regression was used to identify the risk factors and ROC test to complete a mathematic model.Results The 3 and 5-year incidence rate of liver metastasis was 25.0％ and 33.3％,respectively.The risk factors of liver metastasis were lymph node metastasis (LNM),tumor invasive depth (TID),histological grading (G) and preoperative serum tumor markers (PSMs).The mathematic model was:logit (P) =-0.931 + 0.973 × LNM + 0.302 x TID + 0.637 x G + 0.042 x PSMs.Conclusion The risk factors of liver metastasis were LNM,TID,G and PSMs,and the mathematic model could be set up.

Objective To investigate the prognostic risk factors for surgery in patients with cirrhotic portal hypertension.Methods One hundred and sixty one patients with cirrhotic portal hypertension who received surgery in our hospital in the past 10 years were studied.The data were entered into a pre-designed form.24 predictors including patients′ age,sex,degree of liver atrophy,ChildPugh classification,coagulation profile,splenic size,renal function,blood pH,base excess (BE),operative time,volume of ascites,and intraoperative and postoperative hemorrhage were recorded and analyzed.For each of the predictors,2-3 subgroups were compared.Results Seven predictors were clearly related to surgical prognosis:postoperative bleeding within 30h (B0.356,P＜0.001) and a bleeding volume ＞2 L were awarded 3 points; liver volume (B-0.160,P＜0.001) and severe liver atrophy (antero-posterior diameter of the left liver lobe ≤55 mm,oblique diameter of the right lobe ≤110 mm) were awarded three points; blood pH (B0.141,P＜0.001),pH＜7.35 was awarded 2 points; BE (B-0.123,P＜0.001),BE＜-3 (mmol/L) was awarded 2 points; decrease in PLT (B0.065,P =0.015),PLT＜ 3 (T/L) was awarded 2 points; intraoperative bleeding (B0.062,P=0.014),bleeding volume ＞2 L was awarded 2 points; decrease in RBC (B0.053,P=0.024),＜3(G/L) was awarded 1 point.Of the 147 patients who recovered from surgery,all had ≤3 points,except one who had 4 points.Of the 14 patients who died,all had ≥5 points except one who had 4 points.Conclusions Postoperative bleeding (＞2 L),severe liver atrophy (antero-posterior diameter of the left live lobe ≤55 mm,oblique diameter of the right lobe ≤110 mm),blood PH＜7.35,BE ＜-3 (mmol/L),PLT＜30 000(T/L),intraoperative major bleeding (＞2 L) and RBC＜3 (G/L) were significant prognostic risk factors for surgery.For patients who had a score of 5-6 points; death was likely following surgery.A score ≥8 points should be considered as a contraindication to surgery.To reduce operative mortality,active treatment should be given before surgery to keep the score to be 4 points or less.
