Abstract
BACKGROUND Previous mass screening studies have shown that IgA antibodies against Epstein-Barr Virus (EBV) can facilitate early detection of nasopharyngeal carcinoma (NPC), but the impact of EBV-antibody screening for NPC-specific mortality remains unknown. PATIENTS AND METHODS A prospective, cluster randomized, controlled trial for NPC screening (PRO-NPC-001) was conducted in 3 selected towns of Zhongshan City and 13 selected towns of Sihui City in southern China beginning in 2008. Serum samples of the screening group were tested for two previously selected anti-EBV antibodies. Subjects with serological medium risk were subsequently retested annually for 3 years, and those with serological high risk were referred to otorhinolaryngologists for diagnostic check-up. An interim analysis was carried out to evaluate the primary end points of the NPC-specific mortality and the early diagnostic rate, and the secondary end point of the NPC incidence, through linkage with the database of Zhongshan City. RESULTS Among 70 296 total subjects, 29 413 screened participants (41.8% of the total subjects) in the screening group and 50 636 in the control group, 153 (43.3 per 100 000 person-year), 62 (55.3 per 100 000 person-year) and 99 (33.1 per 100 000 person-year) NPC cases were identified. The early diagnostic rates of NPC were significantly higher in the participants (79.0%, P < 0.0001) and the screening group (45.9%, P < 0.0001) compared with the control group (20.6%). Although no differences were found between NPC-specific mortality of the screening group and the control group [relative risk (RR)= 0.82, 95% confidence interval (CI) 0.37-1.79], lower NPC-specific mortality was noticed among participants from the screening group versus the control group (RR = 0.22, 95% CI 0.09-0.49). CONCLUSION IgA antibodies against EBV can identify high-risk population and was effective in screening for early asymptomatic NPC. Although the mortality reduction was not significant in the primary end point, we noted encouraging evidence of a mortality reduction in screening participants in this interim analysis. CLINICAL TRIAL NUMBER NCT00941538.

Abstract
The exclusive process e^{+}e^{-}→ΛΛ[over ¯], with Λ→pπ^{-} and Λ[over ¯]→p[over ¯]π^{+}, has been studied at sqrt[s]=2.396 GeV for measurement of the timelike Λ electric and magnetic form factors, G_{E} and G_{M}. A data sample, corresponding to an integrated luminosity of 66.9 pb^{-1}, was collected with the BESIII detector for this purpose. A multidimensional analysis with a complete decomposition of the spin structure of the reaction enables a determination of the modulus of the ratio R=|G_{E}/G_{M}| and, for the first time for any baryon, the relative phase ΔΦ=Φ_{E}-Φ_{M}. The resulting values are R=0.96±0.14(stat)±0.02(syst) and ΔΦ=37°±12°(stat)±6°(syst), respectively. These are obtained using the recently established and most precise value of the asymmetry parameter α_{Λ}=0.750±0.010 measured by BESIII. In addition, the cross section is measured with unprecedented precision to be σ=118.7±5.3(stat)±5.1(syst) pb, which corresponds to an effective form factor of |G|=0.123±0.003(stat)±0.003(syst). The contribution from two-photon exchange is found to be negligible. Our result enables the first complete determination of baryon timelike electromagnetic form factors.

Abstract
We have mapped a new downy mildew resistance gene, Pl35, derived from wild Helianthus argophyllus to sunflower linkage group 1. New germplasms incorporating the Pl35 gene were developed for both oilseed and confection sunflower Sunflower downy mildew (DM), caused by the oomycete pathogen Plasmopara halstedii, is an economically important and widespread sunflower disease worldwide. Non-race-specific resistance is not available in sunflower, and breeding for DM resistance relies on race-specific resistance to control this disease. The discovery of the novel DM resistance genes is a long-term task due to the highly virulent and aggressive nature of the P. halstedii pathogen, which reduces the effectiveness of resistance genes. The objectives of this study were to: (1) transfer DM resistance from a wild sunflower species Helianthus argophyllus (PI 494576) into cultivated sunflowers; (2) map the resistance gene; and (3) develop diagnostic single-nucleotide polymorphism (SNP) markers for efficient targeting of the gene in breeding programs. The H. argophyllus accession PI 494576 previously identified with resistance to the most virulent P. halstedii race 777 was crossed with oilseed and confection sunflower in 2012. Molecular mapping using the BC2F2 and BC2F3 populations derived from the cross CONFSCLB1/PI 494576 located a new resistance gene Pl35 on linkage group 1 of the sunflower genome. The new gene Pl35 was successfully transferred from PI 494576 into cultivated sunflowers. SNP markers flanking Pl35 were surveyed in a validation panel of 548 diversified sunflower lines collected globally. Eleven SNP markers were found to be diagnostic for Pl35 SNP alleles, with four co-segregating with Pl35. The developed oilseed and confection germplasms with diagnostic SNP markers for Pl35 will be very useful resources for breeding of DM resistance in sunflower.

Abstract
The Third UN High-level Meeting on Non-Communicable Diseases was held on September 2018. The conference carried out a series of activities on the theme of "Time To Deliver", and adopted the 2018 Political Declaration on Non-Communicable Diseases. The new "5×5" strategy for non-communicable diseases prevention and control was clearly put forward, slow progress of non-communicable diseases prevention and control was criticized and the seven major challenges hindering the progress of non-communicable diseases prevention and control was analyzed, the main role and responsibility of governments at all levels in coping with the challenges of non-communicable diseases was reiterated, and put forward clear requirements. The declaration also reiterates the importance of strengthening public health measures. The meeting and declaration aroused strong repercussions and were regarded as a milestone to promote the global prevention and control of non-communicable diseases, and also brought a series of important inspirations for the development of public health in China in the new era. In order to cope with the heavy burden of non-communicable diseases in China, we must give full play to our institutional advantages, mobilization advantages and organizational advantages, adhere to prevention-oriented, emphasize the role of professional public health institutions, and consolidate and strengthen the disease control system and capacity building.

Abstract
OBJECTIVE To investigate the clinical features and treatment of infective endocarditis (IE) patients with acute kidney injury (AKI), and to compare the adverse complications and outcome with IE patients without AKI. METHODS Clinical data of 100 IE cases in Peking University First Hospital from January 2002 to June 2018 were retrospectively reviewed. The patients were divided into AKI group (n=21) and non-AKI group (n=79) based on the AKI network (AKIN) definition. The clinical data and prognosis were compared between the two groups. RESULTS The incidence of AKI was 21%. The average age was (43.7±15.7) years, and the ratio of male to female was 3 ∶1. There was no significant difference in age and gender between the two groups. Compared with non-AKI group, the AKI group had more rash and lower limbs edema (P=0.017 and P=0.001), higher urine blood and protein positive rate (both P<0.001). Lower hemoglobin and serum albumin level (both P<0.001), worse clinical cardiac function (NYHA III-IV, P=0.033) were found in AKI group compared with non-AKI group. There was no significant difference in microbiologic positive rate and pathogenic bacteria sorts between the two groups. Nine patients refused surgery, and the other 91 cases underwent cardiac surgery with cardiopulmonary bypass under general anesthesia, including 19 cases of AKI group and 72 cases of non-AKI group. The ventilation time and intensive care unit (ICU) stay time were longer in AKI group than in non-AKI group (P=0.028 and P=0.003). AKI group needed more red blood cell transfusion (P=0.010). Using the last serum creatinine before surgery as basic level, there was more new-onset AKI cases in AKI group than in non-AKI group. During the median follow-up time 42 months, there was no significant difference in perioperative and follow-up mortality between the two groups (P=0.463 and P=0.581). CONCLUSION More perioperation complications occurred in IE patients with AKI, but no significant difference in in-hospital and follow-up mortality between the AKI and non-AKI groups was observed.

Abstract
We experimentally demonstrate the first use of 1550-nm InAs/GaAs quantum dot semiconductor saturable absorber mirror (QD-SESAM) in the dual-wavelength passively Q-switched (QS) erbium doped fiber (EDF) laser. The dual-wavelength QS lasing was obtained at a pump threshold of 180 mW with the average output power of 2.2 mW and the spacing between the two lasing wavelengths is 14 nm. A large absorption ranging from 1520 to 1590 nm has been realized when no substrate rotation was employed during the molecular beam epitaxy growth of the QD-SESAM indicating the potential to generate a 60 nm spacing of the dual-wavelength QS lasing peaks by changing the positions in the QD-SESAM and replacing EDF by co-doped fiber as gain medium. These results have provided a new opportunity towards achieving the stable and wide wavelength-tunable dual-modes fiber lasers.

Abstract
The PHENIX collaboration presents first measurements of low-momentum (0.4<p_{T}<3 GeV/c) direct-photon yields from Au+Au collisions at sqrt[s_{NN}]=39 and 62.4 GeV. For both beam energies the direct-photon yields are substantially enhanced with respect to expectations from prompt processes, similar to the yields observed in Au+Au collisions at sqrt[s_{NN}]=200. Analyzing the photon yield as a function of the experimental observable dN_{ch}/dη reveals that the low-momentum (>1 GeV/c) direct-photon yield dN_{γ}^{dir}/dη is a smooth function of dN_{ch}/dη and can be well described as proportional to (dN_{ch}/dη)^{α} with α≈1.25. This scaling behavior holds for a wide range of beam energies at the Relativistic Heavy Ion Collider and the Large Hadron Collider, for centrality selected samples, as well as for different A+A collision systems. At a given beam energy, the scaling also holds for high p_{T} (>5 GeV/c), but when results from different collision energies are compared, an additional sqrt[s_{NN}]-dependent multiplicative factor is needed to describe the integrated-direct-photon yield.

Abstract
Objective: To evaluate the clinical manifestations, metal metabolism, imaging characteristics and treatment response in patients with delayed Wilson disease (WD). Methods: Patients with untreated WD (40 with delayed onset and 40 with non-delayed onset) were enrolled. Twenty healthy people were included as normal controls. All patients were evaluated with modified Young scale neural symptom scores, grade of Child liver function and mental symptoms rating scale, magnetic resonance imaging (MRI) scan, magnetic sensitive imaging (susceptibility weighted imaging, SWI), metal metabolism. Corrected phase (CP) was measured at SWI. After 2 week treatment, neurologic symptoms, liver function, and metal metabolism were reviewed. Results: The total score of neurological symptoms in WD patients with delayed onset was lower than that of non-delayed onset (13.00±6.87 vs. 21.13±5.53, P=0.033). The scores of SCL-90 and HAMA depression scales in patients with delayed onset were lower than those of non-delayed onset. On T(2) weighted imaging, areas including substantia nigra and thalamus, the caudate nucleus, globus pallidus, putamen presented high signal rate in patients with delated onset than those with non-delayed (P=0.022, 0.037, 0.022, 0.037, 0.029 respectively). The SWI CP values of cangbai sphere and shell nucleus in patients with delayed onset were lower than those with non-delayed onset. Patients with delayed onset had higher urinary copper than those with non-delayed onset before and after treatment (P=0.040, 0.036). After treatment, the score of abnormal tremor and gait in patients with delayed onset was decreased (P=0.037, 0.044), while as the occurrence of neurological symptoms was increased by 10%, and the liver function level in patients with delayed WD was decreased in 3 cases. Conclusions: The brain of WD patients with delayed onset is mainly composed of metal deposits, however the cell damage is not apparent. Clinical symptoms are characterized by significant liver injury, but relatively mild neurological and psychiatric symptoms. Patients with delayed WD have higher urinary copper excretion than those with non-delayed WD. Chelating agents improves the neurological symptoms in patients with delayed onset.

Study of e^{+}e^{-}→γωJ/ψ and Observation of X(3872)→ωJ/ψ. PHYSICAL REVIEW LETTERS 2019; 122:232002.

Abstract
We study the e^{+}e^{-}→γωJ/ψ process using 11.6 fb^{-1} e^{+}e^{-} annihilation data taken at center-of-mass energies from sqrt[s]=4.008 GeV to 4.600 GeV with the BESIII detector at the BEPCII storage ring. The X(3872) resonance is observed for the first time in the ωJ/ψ system with a significance of more than 5σ. The relative decay ratio of X(3872)→ωJ/ψ and π^{+}π^{-}J/ψ is measured to be R=1.6_{-0.3}^{+0.4}±0.2, where the first uncertainty is statistical and the second systematic (the same hereafter). The sqrt[s]-dependent cross section of e^{+}e^{-}→γX(3872) is also measured and investigated, and it can be described by a single Breit-Wigner resonance, referred to as the Y(4200), with a mass of 4200.6_{-13.3}^{+7.9}±3.0 MeV/c^{2} and a width of 115_{-26}^{+38}±12 MeV. In addition, to describe the ωJ/ψ mass distribution above 3.9 GeV/c^{2}, we need at least one additional Breit-Wigner resonance, labeled as X(3915), in the fit. The mass and width of the X(3915) are determined. The resonant parameters of the X(3915) agree with those of the Y(3940) in B→KωJ/ψ and of the X(3915) in γγ→ωJ/ψ observed by the Belle and BABAR experiments within errors.

Abstract
Using a total of 9.0 fb^{-1} of e^{+}e^{-} collision data with center-of-mass energies between 4.15 and 4.30 GeV collected by the BESIII detector, we search for the processes e^{+}e^{-}→γX(3872) with X(3872)→π^{0}χ_{cJ} for J=0, 1, 2. We report the first observation of X(3872)→π^{0}χ_{c1}, a new decay mode of the X(3872), with a statistical significance of more than 5σ for all systematic fit variations. Normalizing to the previously established process e^{+}e^{-}→γX(3872) with X(3872)→π^{+}π^{-}J/ψ, we find B(X(3872)→π^{0}χ_{c1})/B(X(3872)→π^{+}π^{-}J/ψ)=0.88_{-0.27}^{+0.33}±0.10, where the first error is statistical and the second is systematic. We set 90% confidence level upper limits on the corresponding ratios for the decays to π^{0}χ_{c0} and π^{0}χ_{c2} of 19 and 1.1, respectively.

Abstract
This article makes a comparative analysis of the key recommendations in surveillance, diagnosis, staging and treatment for hepatocellular carcinoma(HCC) from the newest updated guidelines issued by American Association for the Study Liver Disease, European Association for the Study of Liver, and Chinese Society of Clinical Oncology, respectively. It is agreed that patients at high risk for developing HCC should undergo surveillance with ultrasound every six months. Detected hepatic nodules should be diagnosed and followed-up by further imaging examination or liver biopsy. The HCC staging system varies among different guidelines. The studies and clinical trials of system therapy in advanced HCC are becoming new highlights.

Abstract
We collected death data of children under 5-year-old in China from the national child mortality surveillance system from 2010 to 2016. The change of mortality rate and causes of death were described. The mortality rate of Chinese children under 5-year-old decreased from 16.4‰ to 10.2‰ in all areas between 2010 and 2016, from 20.1‰ to 12.4 ‰ in rural areas and from 7.3‰ to 5.2‰ in urban areas, respectively, with a greater average annual decreasing rate in rural areas than urban area. During these years, in addition to traffic accidents and sepsis, other 8 cause-specific mortality rates showed a downward trend. There were substantial decreases of mortality rates of premature birth or low birth weight, birth asphyxia and neural tube defects. In urban areas, the mortality rate of premature birth or low birth weight, birth asphyxia decreased, and the mortality rate of congenital heart disease and diarrhea substantially decreased. However, there was a substantial increase of mortality rate of septicemia in urban areas. In rural areas, the change of major cause-specific mortality rates were consistent with the national trend.

Abstract
Objective: To explore influence of vagus nerve on multiple organ function and immune reaction of T lymphocytes in septic rats. Methods: Forty Sprague-Dawley rats were divided into sham injury group, sepsis group, vagus nerve stimulation (VNS) group, and vagotomy (VGX) group, according to the random number table, with 10 rats in each group. Rats in sepsis group, VNS group, and VGX group were inflicted with sepsis by cecal ligation and puncture (CLP). Rats in VNS group were given electrical stimulation on left cervical vagus nerve for 15 min right after CLP. Rats in VGX group underwent vagotomy of left cervical vagus nerve at 30 min before CLP. At 24 h after CLP, serum of rats was collected to detect levels of alanine transaminase (ALT), aspartate aminotransferase (AST), glycocholic acid (CG), creatine kinase (CK), myocardial creatine kinase (CK-MB), blood urea nitrogen (BUN), and serum creatinine by fully automatic biochemistry analyzer. The left lung of rats was collected to determine wet or dry mass, and wet to dry (W/D) ratio was calculated. The right lung of rats was collected to measure the activity of pulmonary myeloperoxidase (MPO) by enzyme linked immunosorbent assay (ELISA). Spleen of rats was collected to determine the proliferative activity of CD4(+) T lymphocytes by cell counting kit 8, and real-time fluorescence quantitative polymerase chain reaction and ELISA were used to quantify mRNA expressions and levels of interleukin 2 (IL-2), interferon-γ, and IL-4, respectively. Data were processed with one-way analysis of variance and Tukey's honest significant difference test. Results: (1) The levels of serum ALT, AST, CG, CK, CK-MB, BUN, and creatinine, pulmonary W/D ratio, as well as MPO activity of rats in sepsis group were significantly higher than those in sham injury group and VNS group (P<0.01) and were significantly lower than those in VGX group (P<0.01). (2) The proliferative activity of CD4(+) T lymphocytes of rats in sepsis group was 0.93±0.03, which was significantly lower than 1.54±0.07 of rats in sham injury group (P<0.01). The proliferative activity of CD4(+) T lymphocytes of rats in VNS group was 1.15±0.15, which was significantly higher than that of rats in sepsis group (P<0.01). The proliferative activity of CD4(+) T lymphocytes of rats in VGX group was 0.75±0.06, which was obviously lower than that of rats in sepsis group (P<0.01). (3) In comparison with those of rats in sham injury group, the levels of IL-2 and interferon-γ in CD4(+) T lymphocytes of rats in sepsis group were markedly decreased (P<0.01), while the level of IL-4 was significantly increased (P<0.01). In comparison with those of rats in sepsis group, the levels of IL-2 and interferon-γ in CD4(+) T lymphocytes of rats in VNS group were obviously increased (P<0.01), while the level of IL-4 was markedly decreased (P<0.01). As compared with those of rats in sepsis group, the levels of IL-2 and interferon-γ in CD4(+) T lymphocytes of rats in VGX group were markedly decreased (P<0.01), while the level of IL-4 was significantly increased (P<0.01). (4) As compared with those of rats in sham injury group, expressions of IL-2 and interferon-γ mRNA in CD4(+) T lymphocytes of rats in sepsis group were markedly decreased (P<0.01), while expression of IL-4 mRNA was significantly increased (P<0.01). Expressions of IL-2 and interferon-γ mRNA in CD4(+) T lymphocytes of rats in VNS group were obviously increased when compared with those of rats in sepsis group (P<0.01), while expression of IL-4 mRNA was markedly decreased (P<0.01). In comparison with those of rats in sepsis group, expressions of IL-2 and interferon-γ mRNA in CD4(+) T lymphocytes of rats in VGX group were markedly decreased (P<0.01), while expression of IL-4 mRNA was significantly increased (P<0.01). Conclusions: Electrical stimulation of vagus nerve can significantly improve multiple organ dysfunction and reverse immunosuppression of T lymphocytes in septic rats, while vagotomy of vagus nerve may enhance the susceptibility of rats to sepsis.

Objective: To study the clinical symptoms, copper metabolism and imaging characteristics of Wilson disease (WD) carriers and to explore the treatment strategy of WD carriers. Methods: Forty WD carriers, 40 WD patients and 20 normal controls from the First Affiliated Hospital of Sun Yat-sen University from July 2007 to May 2018 were included. The modified Young scale was used for neural symptom scoring, and Child grading of liver function, mental symptoms rating scale, magnetic resonance imaging (MRI) scan, susceptibility weighted imaging (SWI) inspection, metal metabolism tests were also applied to all the included subjects. Corrected phase (CP) was measured by SWI. WD carriers were divided into symptomatic group and asymptomatic group. Symptomatic WD carriers were treated with penicillamine for 2 weeks and zinc gluconate for 3 months, then their neurological symptoms, liver function grade, metal metabolism index were rechecked. Results: Six WD carriers presented with some clinical symptoms, including 5 with neurological symptoms and 4 with liver dysfunction. The score of Hamilton anxiety (HAMA) scale of symptomatic WD carriers was higher than that of normal control group (P=0.021). 85% of carriers had ceruloplasmin level less than 0.26 g/L. 80% of carriers had serum copper between normal controls and WD patients. The free copper level of WD carriers was lower than that of WD patients (P=0.012, 0.019). Urinary copper in symptomatic WD carriers was higher than normal controls (P=0.047). The CP values of thalamus, globus pallidus and putamen in symptomatic WD carriers were lower than those in normal control group. After treatment with penicillamine in symptomatic WD carriers, urinary copper was higher than that before treatment (P=0.036). After treatment, the liver enzymes of symptomatic WD carriers returned to normal, and the score of modified Young scale was lower than before treatment (P=0.031). Conclusions: Mild copper metabolism abnormality is seen in WD carriers. A few carriers have neurological symptoms such as limb tremors, or liver symptoms such as abnormal liver enzymes. Abnormal copper metabolism is more serious in symptomatic WD carriers than in asymptomatic WD carriers. Symptomatic WD carriers can be treated with zinc gluconate.

Abstract
Objective: To improve the understanding of chronic pulmonary aspergillosis (CPA) by analyzing the clinical manifestations, imaging and pathological features, diagnosis, treatment and prognosis of this disease. Methods: Cases of CPA, proven by microbiological evidence based on pathological study in Fuzhou General Hospital of the People's Liberation Army and Affiliated Fuzhou City First Hospital of Fijian Medical University from January 2006 to October 2016 were retrospectively analyzed. Results: The patients consisted of 17 males and 12 females, aged 24 to 75 years, mean (42±16) years. The underlying disorders included post-tuberculosis infection (n=11), bronchiectasis (n=8), chronic obstructive pulmonary disease (n=3) and diabetes mellitus (n=2). The main clinical symptoms included productive cough (n=25), chronic sputum production (n=18) and hemoptysis (n=15). Serum GM antigen tests were performed in 19 cases, and the result was positive in 12 patients. BALF GM antigen tests were performed in 2 cases, both of which were positive. Chest CT showed that the lesions were located predominantly in the upper lobes (n=24). Single cavity with interior irregular intraluminal material (n=16) and multiple cavities with interior irregular intraluminal material (n=10) were the most frequent CT findings, while the "air crescent sign" was found in 13 cases. In the 22 patients who underwent surgical treatment, Aspergillus filaments were found in the cavity (n=20) or the bronchi (n=2) of lung samples, and histological examination didn't show tissue invasion by fungi. Surgical therapy was performed in 22 patients, with complete remission in 19 cases, and death in 3 cases. Anti-fungal therapy was administered in 6 patients, with partial remission in 4, and stable disease in 2 cases. One patient was not treated. Conclusions: CPA is more frequently seen in patients with underlying chronic pulmonary diseases. The common CT findings are single or multiple cavities with interior irregular intraluminal materials. Aspergillus filament in the cavity or bronchi of lung samples, without parenchymal invasion, is the proof of CPA. The surgical cure rate for simple aspergilloma and aspergillus nodule is high, while the risk of operation for chronic cavitary disease is high. GM antigen test may be an evidence for diagnosing CPA.

Abstract
Objective: To investigate the correlation between blood pressure variability (BPV) and target organ damage in children with essential hypertension. Methods: A retrospective review identified 144 children (104 boys (72.2%) and 40 girls (27.8%), age (11.7±2.5)years) diagnosed with essential hypertension at Children's Hospital Affiliated to Capital Institute of Pediatrics from January 2013 to June 2018. Data on indicators for assessing fundus, cardiac, and renal damages obtained included 24-hour ambulatory blood pressure monitoring, BPV, fundus oculi examination, electrocardiogram, echocardiography, renal function, 24-hour urine protein quantitation, urine microalbumin, serum and urine β(2)-microglobulin. According to the existence of target organ damage, subjects were divided into target organ damage group and non-target organ damage group. Comparison between groups was analyzed using independent sample t test, chi square test and pearson correlation analysis. Results: The study included 144 children. There were 108 children (75.0%) diagnosed with phase 1 hypertension and 36 children (25.0%) diagnosed with phase 2 hypertension. Patients in target organ damage group (n=86, 59.7%) had a higher coefficient of 24 h diastolic BPV (14.5%±3.2% vs. 13.2%±2.5% t=2.558, P=0.012), a higher coefficient of daytime systolic BPV (8.2%±2.1% vs. 7.4%±2.0%, t=2.253, P=0.026) and a higher coefficient of daytime diastolic BPV (12.8%±3.4% vs.11.1%±2.4%, t=3.188, P=0.002) compared with patients in non-target organ damage group (n=58, 40.3%). The coefficients of daytime systolic BPV and daytime diastolic BPV were significantly associated with cardiac damage (r=0.190, P=0.023; r=0.366, P<0.01) and renal damage (r=0.167, P=0.046; r=0.167, P=0.045). The coefficient of daytime diastolic BPV was positively correlated with left ventricular mass index (r=0.366, P<0.01). Conclusions: There is a correlation between BPV and target organ damage in children with essential hypertension. Daytime BPV is strongly associated with cardiac and renal damage, and daytime diastolic BPV may predict early cardiac hypertrophy. As a noninvasive method, daytime BPV can provide evidence for early identification of hypertensive target organ damage.

Abstract
OBJECTIVES To explore the role of high mobility group B1 (HMGB1) protein in the post-traumatic endoplasmic reticulum stress (ERS) in rat lung tissues. METHODS The rat model of acute lung injury was established by crushing the hind limbs of rats with standard weight. The first experiment was to divide rats into postural control group and crush groups (6 h, 18 h and 30 h after crushing). The second experiment was to divide rats into postural control group, 18 h crush group, HMGB1 inhibitor sodium butyrate (SB) group and 18 h crush+SB group. The protein expression changes of HMGB1 and ERS- related proteins (GRP78, caspase-12, CHOP and IRE1α) in rat lung tissues were detected with Western blotting. Meanwhile, the pathological changes of rat lungs were observed by HE stain. RESULTS Compared with the postural control group, the expression levels of ERS-related proteins (GRP78, caspase-12, CHOP and IRE1α) and HMGB1 protein in rat lung tissues by crushing the hind limbs of rats were obviously increased. The protein levels reduced at 30 h after crushing but were still higher than those of postural control group and obvious pathological changes of acute lung injury were observed simultaneously in rats. Compared with the 18 h crush group, the expression levels of the ERS-related proteins and HMGB1 protein in rat lung tissues were attenuated in 18 h crush+SB group, and the pathological changes of rat lung injury began to alleviate. CONCLUSIONS HMGB1-ERS pathway activated by traumatic stress can lead to acute lung injury in rats.

Abstract
Objective: To explore mechanism of lung injury of rats induced by inhalation of white smoke from burning smoke pot. Methods: Forty-eight Sprague Dawley rats were divided into control group (n=12) and injury group (n=36) according to the random number table. Rats in injury group were placed in smoke-induced injury experimental equipment fulled with white smoke from burning smoke pot for 5 minutes to make lung injury, and rats in control group were placed in smoke-induced injury experimental equipment fulled with air for 5 minutes to make sham injury. Six rats in injury group at post injury hour (PIH) 6, 24, and 72 and six rats in control group at PIH 72 were collected to observe pathological changes of lung tissue and pathological score of rats in the two groups by hematoxylin-eosin staining, to detect expression of nuclear factor-κB (NF-κB) p65 mRNA in lung tissue of rats by reverse transcriptional polymerase chain reaction, and to detect content of tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), and IL-6 in lung tissue of rats by enzyme-linked immunosorbent assay. Data were processed with one-way analysis of variance and t test. Results: At PIH 72, lung tissue structure of rats in control group was clear and complete, with no inflammatory cell infiltration. At PIH 6, there was edema, hemorrhage, and inflammatory cell infiltration in lung tissue of rats in injury group. At PIH 24, edema, hemorrhage, and inflammatory cell infiltration in lung tissue of rats in injury group aggravated. At PIH 72, area of edema in lung tissue of rats in injury group was enlarged, with obvious hemorrhage and inflammatory cell infiltration. At PIH 6, 24, and 72, pathological score of lung tissue of rats in injury group was (3.43±0.86), (5.39±0.93), and (9.99±0.84) points, respectively, obviously higher than that of rats in control group at PIH 72 [(2.11±0.20) points, t=3.659, 8.450, 22.355, P<0.05]. As time post injury prolonged, pathological scores of lung tissue of rats in injury group were significantly increased (F=121.244, P<0.01). At PIH 6, 24, and 72, expression of NF-κB p65 mRNA in lung tissue of rats in injury group was 15.5±4.3, 25.9±1.8, 30.9±3.5 respectively, significantly higher than that of rats in control group at PIH 72 (7.8±0.8, t=4.315, 20.445, 14.408, P<0.01). As time post injury prolonged, expression of NF-κB p65 mRNA in lung tissue of rats in injury group gradually increased (F=32.691, P<0.01). At PIH 6, 24, and 72, content of TNF-α, IL-1β, and IL-6 in lung tissue of rats in injury group was significantly higher than that of rats in control group at PIH 72, respectively (t=7.650, 8.968, 6.827, 6.726, 8.978, 3.460, 5.420, 13.289, 16.438, P<0.01). At PIH 24, content of TNF-α and IL-1β in lung tissue of rats in injury group was higher than that of rats in the same group at PIH 6 and 72, respectively (t=3.409, -2.549, 4.047, -4.100, P<0.05). At PIH 24 and 72, content of IL-6 in lung tissue of rats in injury group was respectively higher than that of rats in the same group at PIH 6 (t=8.273, 9.711, P<0.05). Conclusions: After inhaling white smoke from burning smoke pot, rats are inflicted with lung injury by increasing expression of NF-κB p65 mRNA and content of TNF-α, IL-1β, and IL-6, and induce pathological changes of edema, hemorrhage, and inflammatory cell infiltration of lung tissue.

Abstract
Objective:To investigatethe effection of white matter abnormality to auditory and speech rehabilitation after cochlear implantation in prelingual deafness children.Method:Thirty-five children with white matter abnormality were included in this study. The degree of leukoaraiosis was evaluated by Scheltens scale based on MRI.The hearing and speechrecovery level was rated by auditory behavior grading standards(CAP) and speech intelligibility grading standards(SIR) at 6 months, 12 months, and 24 months post operation. Result:The CAP scores and SIR scores of the children with white matter abnormality were lower than those of the control group at 6 months after operation (P<0.05).The SIR scores of the children with white matter abnormality at 12 months and 24 months post operation were significantly lower than those of the control group.There was no statistically significant difference between the CAP scores of the two groups at 12 and 24 months after operation(P>0.05).Schelten classification had a greater impact on SIR scores than on CAP scores. Conclusion:The effect of white matter abnormality on auditory and speech rehabilitation after cochlear implantation was related to the degree of leukoencephalopathy. When the lesion of white matter abnormality was larger, the level of hearing and verbal rehabilitation was lower, and the speech rehabilitation was more significantly impacted by white matter lesions degree.

Abstract
Objective: To study the clinicopathologic features, diagnosis and differential diagnosis of chest wall hamartoma of infancy. Methods: The clinical data, histopathologic features and immunophenotype of five chest wall hamartomas were analyzed, and the relevant literature was reviewed. Results: The patients' age ranged from seven months and eight days to 20 months at time of resection, although the lesions were detected in the neonatal period. The male-to-female ratio was 4∶1. Three cases were unilateral, two presented with multiple lesions; and four were located on the right side. CT-scan of the chest showed expansile soft tissue masses with heterogeneous density containing calcifications or ossifications in one or more ribs showing partial bone destruction. Patients were all treated by complete resection. Grossly, the lesions comprised solid and cystic areas, the latter showing hemorrhage. Microscopic examination revealed the solid areas were composed of islands of multilobulated hyaline cartilage interspersed within spindle or oval mesenchymal cells, waved bone and collagen fibers. Around the chondroid tissue, there were focal endochondral ossification and mucus-like background. In addition, there were areas of aneurysmal bone cyst-like changes formed by hemorrhagic dilated cystic spaces. Immunohistochemistry was generally not necessary to establish the diagnosis. Conclusions: Chest wall hamartoma is a rare but benign lesion of infancy, showing characteristic clinicopathologic features. The prognosis are excellent after complete surgical excision.

Abstract
To investigate the prevalence of Peste des petitis ruminants in yaks and cattle in poorly studied areas of China. A total of 1202 and 560 blood samples were collected from yaks and cattle, respectively and processed using a commercial ELISA kit. Multivariable logistic regression model was piloted to find the variables, potentially associated with exposure of PPR infection in yaks and cattle. Results indicated that the overall prevalence of PPR in yaks was 11.2%. A total 66 (11.8%) out of 560 were examined out to be positive to PPR in cattle in Jiangxi province. According to conditional stepwise logistic regression, region, age and gender were found to be the more influencing risk factors in yaks, while region and age were found to be the potential risk factors in cattle. The current results reported the prevalence and associated risk factors of PPR in bovine for the first time in China.

Abstract
Objective: To understand the related risk behaviors, knowledge and status of HIV/AIDS infection among rural adults of Derung minority, to provide relevant messages for the development of HIV/AIDS intervention strategy in this minority group. Methods: We used system sampling method to conduct a cross-sectional survey in 6 administration villages of Derung Township, Gongshan Derung and Nu Autonomous County in Nujiang Lisu Autonomous Prefecture of Yunnan Province, with a sample size estimated as 383. Adult residents with Derung minority in six villages of Gongshan County were involved, with relevant information collected through door-to-door visit. HIV antibody was tested and SPSS 17.0 was used for statistical analysis. Results: Information on 394 valid respondents was collected, with age as between 18 and 65 (34.39±9.74), 80.7% (318/394) as married, 54.0% (213/394) having had primary school education, 13.2% (52/394) as migrant workers. In this population, the overall HIV infection rate appeared as 0.5% (2/400), mainly through sexually transmission. The rate of awareness on HIV/AIDS was 69.8% (275/394), mainly through free publicized materials 50.0% (197/394). Rates on premarital sexual behavior on multiple sexual partners in the past year, on temporary sexual partners in the past year, having commercial sexual experiences in the past year and ever used condoms when engaging in casual sex, were 6.4% (60/366), 18.0%(66/366), 5.7%(21/366), 1.9%(7/366) and 8.0%(25/311), respectively. Conclusions: Few numbers of HIV infections were identified among the migrating workers with Derung minority, with sexual transmission as the major route, along with the increased number of rural migrant workers and the low rates both on AIDS knowledge and condom use, accompanied by the high risk sexual behavior appeared in this rural adult residents of Derung minority. Relative strategies on HIV/AIDS intervention and control should be developed.
