OBJECTIVETo explore the effect of Compound Tongtu Granule (CTG) on intestinal permeability in elderly sepsis patients.

METHODSEighty elderly sepsis patients were randomly assigned to the experimental group and the control group by randomized double blinded method, 40 in each group. On the basis of conventional antiseptic treatment program, patients in the experimental group took CTG, while those in the control group took placebos. The dosage for CTG or placebos was 14.3 g each package, one package each time, twice daily for 14 successive days. Patients' abdominal symptoms and signs, levels of serum inflammatory factors (high-sensitivity C-reactive protein and procalcitonin), levels of plasma endotoxin, and the intestinal permeability (IP, represented by urinary lactulose/mannitol excretion rate) were compared between the two groups before and after treatment.

RESULTSAfter 14-day treatment, patients in the experimental group had improved abdominal symptoms, increased frequency of defecation, significantly decreased levels of plasma endotoxin and IP, when compared with the control group (P < 0.05).

CONCLUSIONCTG could improve the intestinal barrier function in elderly sepsis patients.

Objective To explore the plague epidemical trend of nearly a 10 years data in Qinghai province to provide basis for making the prevention and control measures. Method The regional distribution and time distribution of animal and human plague, monitoring and plague foci of survey data in Qinghai from 2001 to 2010 were analyzed with Excel software 2003. Results In Qinghai province, a total of 167 strains of Yersinia pestis were isolated from infected animals and insects in 10 years. Yersinia pestis was mainly distributed in Wulan,Delinha, Geermu, and Tianjun, along the Qinghai-Xizang railway. Human plague was occurred every year from 2001 to 2010 except 2002, 2007, 2008, and 2010. In the 10 years, there were 37 plague cases and 16 of these cases died, the mortality was 43.24％. The plague cases were mainly distributed in Nangqian, Qumalai, Chenduo,Zhiduo, Xinghai, Tongde, Tianjun, Wulan and Qilian. And these cases were found mostly in the period from May to October, especially in the period from August to October. Major clinical type of the plague cases was lung-type (62.16％,23/37). Conclusions The plague epidemic situation in Qinghai province is still severe, animal plague occurred year after year, and human plague outbreaks occasionally. Monitoring and early warning in the key areas should be strengthened, and the comprehensive measures of plague prevention and control should be carried out to reduce the incidence and prevalence of plague.

Antibody against the angiotensin AT1 receptor (AT1-Ab) could disturb placental development. The placenta is the key organ between mother and fetus. Placental damage will seriously impair fetal growth and development in utero, leading to intrauterine growth restriction (IUGR). Based on the fetal origins of adult disease (FOAD) hypothesis, IUGR could increase a propensity to develop adult onset cardiovascular disease (CVD). The present study was designed to determine whether vascular function has changed in the adult offspring of AT1-Ab positive pregnant rats. Twenty four female rats (8-week-old, AT1-Ab negative) were randomly divided into two groups, immunized and vehicle groups. Immunized group received active immunization to establish AT1-Ab-positive model, while vehicle group was subjected to Freund's adjuvant without antigen. After 8 weeks of immunization, the antibody titers in sera from the female rats were detected by enzyme-linked immunosorbent assay (ELISA). Then all the female rats were mated with normal Wistar male rats and became pregnant. Immunized/vehicle group offspring rats (I offspring/V offspring) were raised to 40-week-old under standard chow feeding. Then the two groups' offspring rats were given a high-salt diet for 12 weeks (4% NaCl in chow feeding). Systolic blood pressure (SBP) was measured dynamically by noninvasive blood pressure system. The vascular ring experiment was performed to detect vascular function and reactivity. As detected by ELISA, the titers of antibody peaked at the 8th week (OD values: 2.75 ± 0.08 vs 0.33 ± 0.01, P < 0.01 vs vehicle group at the same time point). There was no significant difference of SBP between the two groups' offspring rats during the high-salt diet (P > 0.05). Isolated thoracic aortic rings of I offspring had significantly decreased constriction under norepinephrine treatment (P < 0.01 vs V offspring) and significantly decreased dilation under acetylcholine treatment (P < 0.05 vs V offspring). These results suggest that the offspring of AT1-Ab-positive pregnant rats are more susceptible to vascular functional abnormality while being fed high-salt diet.

Objective: The current study was designed to review the clinical practice of intensity modulated radiation therapy (IMRT) in department of radiation oncology, Stanford university medical center. Methods: An inverse planning system ( Corvus, NOMOS corporation) was used to optimize IMRT treatment plans for 2 patients. IMRT using 9 coplanar beams was a part of radical irradiation, combined with external beam therapy. An X-knife radiosurgery boost was added to the first case with nasopharyngeal carcinoma. IMRT was the single modality in the treatment of thoracic vertebral metastases in the second patient. Results: The optimized isodose distributions in various plans showed the best compromise between the target volume dose requirements and the dose constraints placed upon the sensitive structures. The statistics of the plan summarized the volume, dose range in the targets and the organs or tissues concerned. Dose volume histograms offered a direct comparison of dose-volume in tumor and sensitive structures. Conclusions: IMRT can yield a sufficiently homogeneous desired dose distribution which results in a high degree of sparing of sensitive structures. It can be implemented to escalate target doses in some cases.

BACKGROUNDThe temporal response to off-pump anteroapical aneurysm plication has not been well defined. We have evaluated the long-term clinical and functional results of this technique and compared the efficacy with the patch modeling repair.

METHODSFrom March 2005 to May 2010, 163 (115 men and 48 women) consecutive patients were operated on for post-infarction left ventricular aneurysm (LVA), 54 patients underwent patch remodeling (group A) and 109 patients underwent off-pump anteroapical aneurysm plication repair (group B). All patients had simultaneous coronary revascularization, other operative procedures included septoplasty in eight and ablation of ventricular tachycardia in six. Follow-up ranged from 1 to 5 years, short-term and mid-term outcomes, including complications, cardiac function, and mortality, were assessed.

RESULTSEarly mortality was 1.8% for all patients (group A 1 death vs. group B 2 deaths, not significant (NS)). Peri-operative support included intraaortic balloon pumping in 16 (9.8%), (group A 6 patients vs. group B 10 patients, NS) and inotropic drugs in 84 (51.5%), (group A 34 vs. group B 50, NS). During a mean follow-up of (3.7±0.8) years, eight patients died, with four due to cardiac-related causes. No patient required transplantation, and two required use of an implantable cardioverter-defibrillator for ventricular tachycardia. Survival at 1 and 5 years was 95% and 86%, respectively. It did not differ significantly between group A and group B. Functional class improved from 2.90 ± 0.59 to 1.65 ± 0.54 among the mid-term survivors (P < 0.001), with no significant difference between the two groups. Pre-operative risk factors for mortality or poor function were ejection fraction (EF) < 0.35 (OR = 7.9, 95%CI 1.6 - 40.0); congestive heart failure (CHF) (OR = 4.4, 95%CI 1.0 - 19.0); end-systolic volume index (ESVI) > 80 ml/m(2) (OR = 3.7, 95%CI 1.0 - 14.0); and advanced age > 70 years (OR = 2.4, 95%CI 1.0 - 12.0).

CONCLUSIONSThe technique of off-pump anteroapical aneurysm plication associated with coronary grafting can be performed with low operative mortality, providing good symptomatic relief and long-term survival, and similar results can be achieved with patch modeling repair.

Introduction:Patients with metastatic nasopharyngeal carcinoma (NPC) have variable survival outcomes. We have previously shown that an elevated peripheral blood lymphocyte-to-monocyte ratio (LMR) is associated with an increased metastatic risk in patients with primary NPC. The present study aimed to investigate the prognostic value of pretreatment LMR in a large cohort of metastatic NPC patients. Methods:Clinical data of 672 patients with metastatic NPC diagnosed between January 2003 and December 2009 were analyzed. The peripheral lymphocyte and monocyte counts were retrieved, and LMR was calculated. Receiver operating characteristic (ROC) curve analysis and univariate and multivariate COX proportional hazards analyses were performed to evaluate the association of LMR with overall survival (OS). Results:Univariate analysis revealed that an elevated absolute lymphocyte count (≥1.390 × 109/L) and LMR (≥2.475) as well as a decreased monocyte count (<0.665 × 109/L) were significantly associated with prolonged OS. Multivariate Cox proportional hazard analysis showed that LMR (hazard ratio [HR]=0.50, 95%confidence interval [CI]=0.41–0.60, P<0.001), absolute lymphocyte count (HR=0.77, 95%CI=0.64–0.93, P=0.007), and monocyte count (HR=1.98, 95%CI=1.63–2.41, P<0.001) were independent prognostic factors. By stratification analyses, only LMR remained a significant predictor of prognosis. Conclusion:We identified pretreatment LMR as an independent prognostic factor for patients with metastatic NPC. Independent validation of our findings is needed.

BACKGROUNDTakayasu arteritis (TA) is a rare inflammatory arteriopathy of unknown etiology. The aim of this study was to investigate the genetic susceptibility to TA in a Chinese population.

METHODSFour single nucleotide polymorphisms (SNPs) those locate in the IL12B region (rs56167332), the MLX region (rs665268), the FCGR2A/FCGR3A locus (rs10919543), and the HLA-B/MICA locus (rs12524487), associated with TA in different population, were genotyped in 123 Chinese TA patients and 147 healthy controls from January 2013 to August 2014. A Chi-square test was used to test for genotype/allele frequencies variants.

RESULTSAmong the four SNPs, rs10919543 was found to be significantly associated with TA in the studied population. The GG genotype of rs10919543 at the FCGR2A/FCGR3A locus is a high risk factor (odds ratio [OR] = 6.532, 95% confidence interval [CI] = 2.402 - 17.763, P < 0.001) for TA. Among TA patients, the level of eosinophil granulocytes (Eos) in the peripheral blood was observed to be higher in the GG group of rs10919543 (n = 23, Eos = 0.11 [0.08, 0.17] ×109/L) than the GA + AA group (n = 100, Eos = 0.08 [0.05, 0.13] ×109/L, P = 0.028). No correlation between the genotypes of the other three SNPs and TA patients was observed.

CONCLUSIONSOur findings revealed unique genetic pattern in Chinese TA patients that may be partly responsible for the higher risk of TA in this population. FCGR2A/FCGR3A-related immune disorder might contribute to the etiology of TA.
