Co-authors analysis showed that the co-authors network is of the small world effect. Subject evolution analysis revealed that the subjects involved in studies on precision medicine are increasingly rich with genomics, drug treatment and oncology accounted a large proportion. Analysis of the evo-lution in genomics, drug treatment and oncology displayed that the subjects involved in studies on precision medi-cine have experienced macro-stage, micro-stage, and combined macro- and micro-stage.

Objective To explore serum IL-6 (interleukin-6) ,IL-10 (interleukin-10), the WBC (white blood cell count), CRP (C-reactive protein)and PCT ( procalcitonin ) level in early diagnosing of in children with hand, foot and mouth disease and bacterial infection. Methods 63 children in bacterial infection group and virus infection group respectively,collected 63 children in normal control group by physical examination. Enzyme-linked immunosorbent assay (ELISA) double antibody clamp method was used to determine serum IL-6 and IL-10 level. Immune turbidimetric , enzyme-linked fluorescent were used to detected serum CRP , PCT. WBC results were also compared. Resluts Serum IL-6, IL-10, CRP and PCT level were higher in normal control group compared with virus infection group , the WBC level was slightly lower than normal control grou with statistically different IL-6, IL-10, CRP level (P < 0.05);serum IL-6, IL-10, WBC, CRP and PCT levels in Bacteria infection group were higher than virus infection group and normal control group , while their serum WBC, CRP and PCT level were statistically significant compared to virus infection group (P < 0.05),IL-6 and IL-10 were no statistical different (P > 0.05). Conclusion IL-6, IL-10 levels increased significantly in the early stage of hand,foot and mouth disease, but in the aspect of combination of bacterial infection and bacterial infection, their clinical value was not so significant. WBC, CRP and PCT level had important value for early diagnosis in hand, foot and mouth disease with bacterial infection.

Twenty five children with recurrent wheezing,intractable cough and recurrent respiratory infection were examined and treated by electron-bronchoscopy.Among them 9 cases were diagnosed as tracheobronchomalacia.simple endobronchial inflammation was found in 7 cases,foreign body in bronchus were found in 6 cases,bronchostenosis in 2 cases and pulmonary hemorrhage in 1 case.Tracheobronehomalacia is one of the leading causes of recurrent wheezing and intractable cough in children.Electron-bronchoscopie examination is important in diagnosis of tracheobronchomalacia in children.

Objective To investigate the pathological manifestations of acute?stage radioactive myocardial damage and related mechanisms using an experimental animal model. Methods A total of 12 adult male Sprague?Dawley rats were randomly divided into control group and radiation group. In the radiation group, the model of radiation?induced myocardial damage was established by the irradiation of the anterior myocardial territory with 6?MV X?ray at a single dose of 20 Gy, and at 14 days after irradiation, HE staining was used to observe the morphological changes of cardiomyocytes and intercellular matrix, and Masson staining was used to observe the distribution of collagen fibers. The collagen volume fraction ( CVF) was used for semi?quantitative analysis. ELISA was used to measure the activity of total superoxide dismutase ( T?SOD) and the concentration of malondialdehyde ( MDA ) , and Western blot was used to measure the expression of the fibrosis marker protein collagen type I ( COL?1 ) and the endoplasmic reticulum stress?related proteins GRP78 and CHOP. The t?test, t ’?test, or nonparametric rank sum test was used for comparison between groups. Results At 14 days after local irradiation of the heart, the radiation group had disordered arrangement of cardiomyocytes, marked edema, rupture of some cardiomyocytes, mild karyopyknosis in cardiomyocytes, and infiltration of inflammatory cells in the myocardial interstitium, compared with the control group. Collagen fibers in the myocardial tissue were mainly distributed in the perivascular area and cardiomyocyte interstitium. The radiation group had a significantly higher CVF than the control group ( 11?35% vs. 5?23%, P=0?000 ) and a significant increase in the expression of COL?1 compared with the control group ( P=0?000) . The radiation group had significant increases in the activity of T?SOD and the concentration of MDA in the myocardial tissue compared with the control group ( T?SOD:156?61 U/mgprot vs. 137?06 U/mgprot, P= 0?042;MDA:2?36 nmol/mgprot vs. 1?31 U/mgprot, P=0?007) . Compared with the control group, the radiation group showed significant increases in the expression of endoplasmic reticulum stress?related proteins GRP 7 8 and CHOP ( P= 0?037 and 0?009 ) . Conclusions The pathological manifestations of acute?stage myocardial damage include degeneration of cardiomyocytes, inflammatory exudation in the interstitium, and deposition of collagen in the perivascular area and myocardial interstitium. Myocardial fibrosis can be observed in the acute stage of radiation?induced myocardial damage, and the mechanism may be related to oxidative stress and endoplasmic reticulum stress induced by radioactive rays.

to observe the infarction volume.Nitrate reductase assay was used to detect the level of NO in brain tissue of the rats.The level of S100βin brain was detected by ELISA method.Results Compared with model group,the brain infarction volumes of the rats 24 and 72 h after cerebral ischemia reperfusion in curcumin group were significantly decreased (P<0.05).Compared with sham operation group,the NO and S100βlevels in the brain tissue 24 and 72 h after cerebral ischemia reperfusion of the rats in model group were significantly increased(P<0.05);compared with model group,the levels of NO in the brain tissue 24 and 72 h after cerebral ischemia reperfusion in curcumin group were remarkably decreased (P<0.05);compared with modee group,the level of S100βin the brain tissue 72 h after cerebral iscemia reperfusion in curcumin group was remarkably decreased (P < 0.05 ). Conclusion Curcumin can significantly reduce the degree of ischemia reperfusion injury in the rats and reduce the levels of NO and S100βin brain tissue,which suggests that the decrease of NO and S100βlevels in brain tissue may be associated with the neuroprotective effect of curcumin.

Objective To examine the effects of different pre-treatment nutritional status and inflammatory markers on acute adverse reactions in esophageal cancer patients during concurrent intensity-modulated radiation therapy (IMRT) and chemotherapy.Methods The acute adverse reactions of 338 eligible esophageal cancer patients who received concurrent IMRT and chemotherapy in our hospital from 2006 to 2014 were reviewed.The effects of different pre-treatment nutritional status, such as body mass index level (BMI), albumin level (ALB), total lymphocyte count (TLC), the presence or absence of anemia, and inflammatory indicators including neutrophil lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR), on acute adverse reactions in the patients were examined.Data were analyzed using the chi-square test with continuity correction and logistic regression analysis.Results The incidence rate of malnutrition in the patients based on their nutritional status was 5.62%-54.14%.The incidence rate of grade≥2 acute radiation esophagitis (RE) was significantly higher in the low ALB group than in the normal ALB group (P=0.000).The incidence rate of adverse reactions in the hematologic system increased as TLC decreased (P=0.006), but the incidence rate of acute radiation pneumonitis (RP) was reduced as TLC decreased (P=0.001).In addition, the incidence rate of grade ≥2 acute RE was significantly higher in the anemia group than in the non-anemia group.Inflammatory marker analysis demonstrated that the incidence rate of acute RE was significantly higher in the high NLR group and high PLR group than in the low NLR group and low PLR group (P=0.000 and P=0.024, respectively).Logistic regression analysis of nutritional status and inflammatory markers showed that TLC was an independent risk factor for acute adverse reactions in the hematologic system (P=0.001), and ALB and PLR were independent risk factors for acute RE (P=0.017 and P=0.011,respectively).Conclusions Nutritional status and inflammatory markers are associated with concurrent chemoradiotherapy-induced acute adverse reactions in esophageal carcinoma patients, and hence may be valuable indicators of acute adverse reactions during treatment.In addition, nutritional treatment and support care should be actively provided to the patients to prevent the development of acute adverse reactions during treatment.

OBJECTIVETo observe the clinical characteristics and short-term survival of patients with splenomegaly and acute-on-chronic liver failure related to chronic HBV infection.

METHODSElectronic medical records of patients with acute-on-chronic liver failure were collected to analyze the clinical parameters and 4-week survival of patients with or without splenomegaly.

RESULTSOf the 149 patients enrolled, the overall 28-day mortality rate was 48.3%, which was lower in patients with enlarged spleen than those without (34.2% vs 54.1%, P=0.034). Compared with patients without splenomegaly, patients with splenomegaly had lower platelet counts (P=0.001), lower ALT levels (P=0.005) and lower PT-INR (P=0.010). Although the occurrence of hepatic encephalopathy was comparable between patients with or without splenomegaly, severe conditions were more frequent in those without splenomegaly. Hepatic encephalopathy grades, serum creatinine levels, neutrophil percentages over 70%, PT-INR and splenomegaly were independent factors associated with the 28-day survival, and this novel model was superior to model of end-stage of liver disease in predicting the 4-week survival (P=0.017).

CONCLUSIONPatients with splenomegaly that evolves into acute-on-chronic liver failure have unique clinical characteristics and further clinical observations are warranted.

Objective To analyze the clinical efficacy,toxicity and survival prognosis of patients diagnosed with Siewert type Ⅱ and Ⅲ locally advanced adenocarcinoma of esophagogastric junction (AEG) undergoing preoperative involved-field irradiation with concurrent chemotherapy. Methods A total of 45 cases were recruited in this prospective clinical trial. Prior to surgery, patients received 2 cycles of chemotherapy with XELOX and concurrent radiotherapy ( a total of 45 Gy in 25 fractions,5 times weekly). After 6-8 weeks,they underwent surgical resection. After the surgery,patients received 6 cycles of adjuvant chemotherapy. The completion of preoperative neoadjuvant chemoradiotherapy, postoperative pathological status,TNM down-staging effect and adverse reactions were observed. Kaplan-Meier method was applied to estimate survival analysis. Results All 45 patients completed preoperative neoadjuvant chemoradiotherapy. Among them, 39 patients completed 2 cycles of chemotherapy, and 6 patients completed 1 cycle of chemotherapy. The median time of surgical interval was 6 weeks. The R0resection rate was 96%.The pathological complete response (pCR) rate was 22%. The TNM down-staging rate was 69%.The incidence of acute radiation-induced esophagitis or gastritis was 44% and the incidence of radiation-induced pneumonitis was 7%. The incidence of grade 1-3 leukocytopenia,thrombocytopenia and neutropenia was 78%,47% and 44%,respectively. In terms of gastrointestinal reactions,the incidence of nausea,vomiting and loss of appetite was 62%,24% and 71%,respectively. No hematologic or nonhematologic adverse effects was observed at grade 4 or 5.The median follow-up time was 30 months. 11 patients died of cancer,1 patient was treatment-related death in the perioperative period and 1 patient died of pneumonia. The 1-,2-and 3-year progression-free survival (PFS) rates were 90%,70% and 67%,respectively. The 1-,2-and 3-year overall survival rates were 95%,80% and 75%,respectively. The 1-,2-and 3-year local control rates were 95%,84% and 84%, respectively. The 1-, 2-and 3-year distant metastasis rates were 7%, 25% and 25%, respectively. Conclusions Preoperative involved-field irradiation with concurrent chemotherapy yields relatively high clinical efficacy and is well tolerated by patients with Siewert typeⅡandⅢlocally advanced AEG.Patients are recommended to receive 4 cycles of adjuvant chemotherapy following neoadjuvant chemoradiotherapy and surgery.

Sudden sensorineural hearing loss (SSNHL) refers to the sudden and unexplained sensorineural hearing loss within 72 h and a decrease in hearing of ≥30 dB affecting at least 3 consecutive frequencies. It is one of the common emergencies in neurology and otolaryngology. Early etiological evaluation and systematic and targeted treatment are very important for delaying the progression of SSNHL and restoring hearing. Recent studies have shown that SSNHL overlaps with vascular risk factors of ischemic stroke, and may predict the risk of ischemic stroke. SSNHL may be one of the clinical manifestation and even the prodromal symptoms of ischemic stroke, especially the infarction of the blood supply area of the anterior inferior cerebellar artery or its branch internal auditory artery. Although these factors can not fully reveal the relationship between SSNHL and ischemic stroke, they are enough to warn clinicians that they should consider the possibility of ischemic stroke when receiving patients with SSNHL. Screening of vascular risk factors for patients with SSNHL as early as possible is helpful to avoid the risk of recurrence of ischemic stroke.
