Abstract
Acne keloidalis is a primary scarring alopecia characterized by longstanding inflammation in the scalp causing keloid-like scar formation and hair loss. Histologically, acne keloidalis is characterized by mixed leukocytic infiltrates in the acute stage followed by a granulomatous reaction and extensive fibrosis in the later stages. To further explore its pathogenesis, bulk RNA sequencing, single-cell RNA sequencing, and spatial transcriptomics were applied to occipital scalp biopsy specimens of lesional and adjacent no-lesional skin in patients with clinically active disease. Unbiased clustering revealed 19 distinct cell populations, including 2 notable populations: POSTN+ fibroblasts with enriched extracellular matrix signatures and SPP1+ myeloid cells with an M2 macrophage phenotype. Cell communication analyses indicated that fibroblasts and myeloid cells communicated by SPP1 signaling networks in lesional skin. A reverse transcriptomics in silico approach identified corticosteroids as possessing the capability to reverse the gene expression signatures of SPP1+ myeloid cells and POSTN+ fibroblasts. Intralesional corticosteroid injection greatly reduced SPP1 and POSTN gene expression as well as acne keloidalis disease activity. Spatial transcriptomics and immunofluorescence staining verified microanatomic specificity of SPP1+ myeloid cells and POSTN+ fibroblasts with disease activity. In summary, the communication between POSTN+ fibroblasts and SPP1+ myeloid cells by SPP1 axis may contribute to the pathogenesis of acne keloidalis.

Abstract
Objective: To analyze the characteristics of patients with chronic rhinosinusitis (CRS) in the South China region based on pathological tissue biomarkers for regional comparison. Methods: The study population consisted of CRS in-patients in the First Affiliated Hospital of Sun Yat-sen University from October 2019 to June 2022. Among all the 181 cases, 123 of them were male and 58 were female, with an average age of 40. Retrospectively collected clinical data included demographic information, preoperative symptom scores, preoperative endoscopic images, preoperative paranasal sinus computed tomography scanning images, and inflammatory serological features. In addition, 52 variables of pathological tissue biomarkers including cytokines, chemokines and remodeling factors were collected for analysis. Cluster analysis was performed on the integrated data of training set through centroid-based clustering algorithm, and the inflammatory characteristics, post-operation control status, and airway diseases comorbidity of each endotype were analyzed. R project (version 4.2.2) was used in statistical analysis. Results: Cluster analysis divided 181 patients with CRS into 4 endotypes. Cluster 1 (n=101, 55.80%) showed a locally low inflammatory status. Cluster 2 (n=23, 12.71%) showed a mixed type of inflammation with predominantly neutrophilic inflammation and tissue remodeling. Cluster 3 (n=11, 6.08%) was characterized by type Ⅱ inflammation without tissue remodeling. Cluster 4 (n=46, 25.41%) was mainly characterized by type Ⅱ inflammation with tissue remodeling, showing higher comorbidity rate of asthma and allergic rhinitis. This cluster presented more severe symptoms, significant olfactory dysfunction, extensive overall inflammation based on objective examination results, a notable increase in total eosinophil count and proportion in peripheral blood, and the highest uncontrolled rate observed one year post-surgery. In comparison to other regions, the endotype classification of CRS in Southern China was characterized by a predominant pattern of locally low inflammatory status, a moderate level of type Ⅱ inflammation with tissue remodeling, and a lesser presence of neutrophilic inflammation. Conclusion: CRS distribution in Southern China is mainly characterized by low inflammatory endotype and type Ⅱ inflammation with tissue remodeling. The latter shows more severe clinical manifestations and higher uncontrol rate after surgery.

Abstract
Objective: To examine the radiomics model based on high-resolution T2WI and diffusion weighted imaging (DWI) in predicting microsatellite stability in patients with stage Ⅱ and Ⅲ rectal cancer. Methods: From February 2016 to October 2020, 175 patients with stage Ⅱ and Ⅲ rectal cancer who met the inclusion criteria were retrospectively collected. There were 119 males and 56 females, aged (63.9±9.4) years (range: 37 to 85 years), including 152 patients with microsatellite stability and 23 patients with microsatellite instability. All patients were randomly divided into the training group (n=123) and the validation group (n=52) with a ratio of 7∶3. The region of interest was labeled on the T2WI and DWI images of each patient using the ITK-SNAP software, and PyRadiomics was used to extract seven kinds of radiomics features. After removing redundant features and normalizing features, the least absolute shrinkage and selection operation were used for feature selection. One clinical model, three radiomics models and one clinical-radiomics model were constructed in the training group based on a support vector machine. The area under receiver operating characteristic curve (AUC), sensitivity, specificity, and accuracy were used to evaluate the performance of the models in the verification group. Results: Three clinical features (age, degree of tumor differentiation, and distance from the lower edge of the tumor to the anal edge) and six radiomics features (two DWI-related features and four T2WI-related features) most related to microsatellite status of rectal cancer patients were selected. The AUC of the clinical-radiomics model in the training group was 0.95. In the validation group, the AUC was 0.81, better than the clinical model (0.68, Z=0.71, P=0.04), and equivalent to the T2WI+DWI model (0.82, Z=0.21, P=0.83). Conclusions: Radiomic features based on preoperative T2WI and DWI were related to microsatellite stability in patients with stage Ⅱ and Ⅲ rectal cancer and showed a high classification efficiency. The model based on the features provided a noninvasive and convenient tool for preoperative determination of microsatellite stability in rectal cancer patients.

Abstract
Due to the lack of effective early diagnosis and treatment, gallbladder cancer(GBC) remains a malignant tumor with extremely high malignancy and poor prognosis. Therefore, high quality studies are required to break through the bottleneck in GBC diagnosis and treatment. This article reviewed the domestic and foreign GBC research published in 2021, presenting a comprehensive summary of the important advances in the field of clinical diagnosis and treatment. Latest epidemiological data and risk factors, emerging diagnostic methods of peripheral blood laboratory tests and imaging, new pathologic classification system, hot topics and controversies of surgical treatment as well as the dynamics of systemic treatment of GBC are reviewed in the article. The present findings may contribute to a more efficient means of diagnosis and treatment for GBC and hold the promise of improved outcomes for patients with GBC.

Abstract
Nipah virus disease (NVD) is a newly emerged zoonosis with a case fatality rate of 40%-75%. NVD is a severe threat to human health and the development of livestock farming. NVD has become one of the emerging infectious diseases with great concern globally during more than 20 years. Nipah virus (NiV) is a pathogen for NVD, the natural host of which is Fruit bats of the Pteropodidae family. The clinical spectrum of NiV infection is broad, including asymptomatic infection, acute respiratory infection, fatal encephalitis, and even death. Since NiV was first identified in Malaysia in 1999, it has been prevalent mainly in Southeast Asia and South Asia. NiV is primarily transmitted to humans through bat-pig-human, contaminated food. Currently, there are no specific therapeutic drugs and vaccines for NVD. Although there are no cases of NVD reported in China, which has close personnel and trade exchanges with major NVD-endemic countries, and NiV antibody has also been detected in relevant bats. There is a potential risk of importing NVD and domestic outbreaks in the future in this country. This paper provides a systematic review of the research progress in the prevention and control of NVD etiology, epidemiology, clinical manifestations and laboratory diagnosis to help relevant staff to understand NVD more comprehensively and systematically.

Abstract
Objective: To compare the short-term and long-term outcomes between robotic-assisted and laparoscopic-assisted radical right hemicolectomy in patients with adenocarcinoma of the right colon. Methods: Retrospective review of a prospectively collected database identified 288 right colon cancer patients who underwent either robotic-assisted (n=57) or laparoscopic-assisted right hemicolectomy (n=231) between October 2014 and October 2020 at Department of Gastrointestinal Surgery, the Affiliated Hospital of Qingdao University. There were 161 males and 127 females, aging (60.3±12.8) years (range: 17 to 86 years). After propensity score matching as 1∶4 between robotic-assisted and laparoscopic-assisted right hemicolectomy, there were 56 cases in robotic group and 176 cases in laparoscipic group. Perioperative outcomes and overall survival were compared between the two groups using t test, Wilcoxon rank sum test, χ2 test, Fisher exact test, Kaplan-Meier method and Log-rank test, respectively. Results: The total operative time was similar between the robotic and laparoscopic group ((206.9±60.7) minutes vs. (219.9±56.3) minutes, t=-1.477, P=0.141). Intraoperative bleeding was less in the robotic group (50 (20) ml vs. 50 (50) ml, Z=-4.591, P<0.01), while the number of lymph nodes retrieved was significantly higher (36.0±10.0 vs. 29.0±10.1, t=4.491, P<0.01). Patients in robotic group experienced significantly shorter hospital stay, shorter time to first flatus, and defecation (t: -2.888, -2.946, -2.328, all P<0.05). Moreover, the overall peri-operative complication rate was similar between robotic and laparoscopic group (17.9% vs. 22.7%, χ²=0.596,P=0.465). The 3-year overall survival were 92.9% and 87.9% respectively and the 3-year disease-free survival rates were 83.1% and 82.6% with no statistical significance between the robotic and laparoscopic group (P>0.05). Conclusions: Compared to laparoscopic-assisted right hemicolectomy, robot-assisted right hemicolectomy could improve some short-term clinical outcomes. The two procedures are both achieving comparable survival.

Abstract
Objective: To observe the effect of autologous platelet-rich plasma (PRP) combined with Meek microskin grafts in repairing the wounds of limbs in severely burned patients, and to explore the mechanism. Methods: The prospective controlled research method was used. From September 2016 to January 2020, 16 patients aged 18-69 years, with extensive deep burns, including 9 males and 7 females, who met the selection criteria were admitted to the Department of Burns and Plastic Surgery of the 909th Hospital of the Joint Logistic Support Force of PLA. The bilateral limbs with similar injury in 8 patients were divided into Meek skin grafting+PRP group and Meek skin grafting alone group according to the random number table; in the other 8 patients, the limbs with severer injury were included in Meek skin grafting+PRP group, and the limbs on the other side were included in Meek skin grafting alone group. The wounds of affected limbs in the two groups were treated correspondingly. On post surgery day (PSD) 10, the survival and fusion of Meek microskin grafts were observed and the survival rate and fusion rate were calculated; the histological morphology and the angiogenesis of the basal tissue of Meek microskin graft were observed by hematoxylin-eosin staining and immunohistochemical staining, respectively, with the microvessels being counted. Data were statistically analyzed with paired sample t test. Results: On PSD 10, the wounds of affected limbs in Meek skin grafting+PRP group were dry, and most of the transplanted skin grafts were closely adhered to the basal tissue; while a small amount of exudate could be found in the wounds of affected limbs in Meek skin grafting alone group, and a small part of the transplanted microskin grafts fell off or poorly attached to the basal tissue. On PSD 10, the survival rate and the fusion rate of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting+PRP group were (94±3)% and (86±4)%, which were significantly higher than (89±4)% and (79±4)% of Meek skin grafting alone group, respectively (t=3.633, 4.229, P<0.01). On PSD 10, the basal epidermis was closely connected with dermis of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting+PRP group, with more inflammatory cell infiltration and active microvascular hyperplasia, while the basal epidermis was less closely connected with dermis of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting alone group, with obvious degeneration of collagen fibers under the dermis, less inflammatory cell infiltration, and slightly poor microvascular hyperplasia. On PSD 10, the distribution of microvessels in basal tissue of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting+PRP group were densely clustered, while the distribution of microvessels in Meek skin grafting alone group were scattered, sparse, and dotted. On PSD 10, the number of microvessels in basal tissue of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting+PRP group was 36±6 in each 400-fold visual field, which was significantly more than 29±7 of Meek skin grafting alone group (t=2.671, P<0.05). Conclusions: Autologous PRP can effectively promote the survival rate and fusion rate of Meek microskin grafts in the wounds of limbs after escharectomy in severely burned patients by promoting angiogenesis at the base of Meek microskin grafts.

Abstract
Electron antineutrino appearance is measured by the T2K experiment in an accelerator-produced antineutrino beam, using additional neutrino beam operation to constrain parameters of the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) mixing matrix. T2K observes 15 candidate electron antineutrino events with a background expectation of 9.3 events. Including information from the kinematic distribution of observed events, the hypothesis of no electron antineutrino appearance is disfavored with a significance of 2.40σ and no discrepancy between data and PMNS predictions is found. A complementary analysis that introduces an additional free parameter which allows non-PMNS values of electron neutrino and antineutrino appearance also finds no discrepancy between data and PMNS predictions.

Abstract
Abstract
Background
Lipoprotein (a) [Lp(a)] is recently recognized as a risk factor of atherosclerosis, and the development of coronary artery disease (CAD) in women is not fully understood.
Purpose
The present study aimed to examine the association of Lp(a) levels with the presence and severity of (CAD) in female patients pre- and post-menopause.
Methods
A total of 3712 female patients who received coronary angiography were consecutively enrolled. The level of Lp(a) was measured and compared among patients with and without CAD or myocardial infarction (MI), pre- or post- menopause. The association of Lp(a) with the presence of CAD and the severity of coronary atherosclerosis assessed by Gensini Score were examined.
Results
The average of Lp(a) levels were elevated as age increased in female subjects. Notably, women after menopause had higher Lp(a) levels compared with that before menopause [16.8 mg/dL (IQR 7.54–41.12 mg/dL) vs. 14.7 mg/dL (IQR 6.72–30.82 mg/dL), p=0.002]. Furthermore, multiple logistic regression analysis identified that Lp(a) >30mg/dL was an independent risk factor of CAD in the postmenopausal female (OR1.38, 95% CI 1.13–1.69, p=0.002). Finally, Lp(a) had a positive correlation with Gensini score (r=0.11, p<0.001), and Lp(a) >30mg/dL was an independent risk factor for high Gensini score (OR 1.43, 95% CI 1.14–1.79, p<0.001). While such results were not observed in the premenopausal females.

Abstract
Gastric cancer is the most common gastrointestinal cancer in China. The morbidity and mortality are extremely high and there are significant challenges in the treatment of gastric cancer. Recent studies have shown that the expressions of T lymphocyte subsets vary in the immune microenvironment of gastric cancer patients. T lymphocytes are not only the main effector cells of human cellular immunity, but also the important immunoregulatory cells. T lymphocytes not only reflect the state of the tumor microenvironment, but also closely relate with the prognosis of patients. T lymphocytes play a crucial guiding role in the clinical treatment. Currently, clinical trials related to immunological checkpoint inhibitors are still underway, among which PD-1/PD-L1 monoclonal antibody has been approved for the treatment of gastric cancer. The applications of tumor vaccines and adoptive cell therapies in gastric cancer are also being explored. How to screen patients suitable to immunotherapy, develop the best combination therapy and evaluate the effectiveness of immunotherapy need to be studied and solved.

Abstract
OBJECTIVE To investigate the expression changes of high mobility group box-1 (HMGB-1) and tissue factor (TF) and their correlation in the serum of sepsis rat models. MATERIALS AND METHODS 30 rats were divided into the sham-operated group, 15 rats were in the control group. The cecal ligation and puncture method was used to make the animal model with abdominal infection induced by sepsis. There were 15 rats in the sepsis group among which they were divided into 3 subgroups at different time points after modeling (after 6 hours, 12 hours, 24 hours). Cardiac function indicators of the rats in each subgroup were monitored, including heart rate (HR), left ventricular end-diastolic pressure (LVEDP) and left ventricular developed pressure (LVDP), and enzyme-linked immunosorbent assay (ELISA) was used to test the changes of the expression levels of HMGB-1 and TF in the serum of the rats after 6 hours, 12 hours, 24 hours. Pearson correlation analysis was used to analyze the correlation between HMGB-1 and TF. RESULTS HR and LVEDP of the rats in the sepsis group were significantly higher than those of the rats in the control group. The differences were statistically significant (p<0.050). LVDP of the rats in the sepsis group was markedly lower than that of the rats in the control group. The differences were statistically significant (p<0.050). The expressions of HMGB-1 and TF of the rats in the subgroups of the sepsis group were higher than those of the rats in the control group after 6 hours, 12 hours, 24 hours; the expression levels of HMGB-1 and TF of the rats with sepsis increased with time. The differences were statistically significant (p<0.050). When the expressions of HMGB-1 and TF of the rats in the sepsis group were compared with each other within the group the differences were significantly different (p<0.050). The expressions of HMGB-1 and TF in the subgroups at the 24th hour were significantly higher than those at the 6th hour. The differences were statistically significant (p<0.050). The differences of the expression of TF of the rats in the control group were not statistically significant (p>0.050). There was a significant positive correlation between HMGB-1 and TF of the rats in the sepsis group (r=0.772, p=0.002). CONCLUSIONS The expression levels of HMGB-1 and TF of the rats with sepsis gradually increased with time, and the level of HMGB-1 was positively correlated with the level of TF.

Abstract
Background Little is known about the benefits of adjuvant chemotherapy (adj) in the older population with locally advanced rectal cancer (larc). We evaluated use of adj, survival outcomes, and adj-related toxicity in older patients with larc. Methods Our retrospective review included 286 patients with larc (stages ii and iii) diagnosed between January 2010 and December 2013 in Nova Scotia who underwent curative-intent surgery. Baseline patient, tumour, and treatment characteristics were collected. The survival analysis used the Kaplan-Meier method and Cox regression statistics. Results Of 286 identified patients, 152 were 65 years of age or older, and 92 were 70 years of age or older. Median follow-up was 46 months, and 163 patients (57%) received neoadjuvant chemoradiation. Although adj was given to 81% of patients (n = 109) less than 65 years of age, only 29% patients (n = 27) 70 years of age and older received adj. Kaplan-Meier analysis suggested a potential survival advantage for adj regardless of age. In multivariate Cox regression analysis, Eastern Cooperative Oncology Group performance status, T stage, and adj were significant predictors of overall survival (p < 0.04); age was not. Similarly, N stage, neoadjuvant chemoradiation, and adj were significant predictors of disease-free survival (p < 0.01). Poor Eastern Cooperative Oncology Group performance status was the most common cause of adj omission. In patients 70 years of age and older, grade 1 or greater chemotherapy-related toxicities were experienced significantly more often by those treated with adj (85% vs. 68% for those not treated with adj, p < 0.05). Conclusions Regardless of age, patients with larc seem to experience a survival benefit with adj. However, older patients are less likely to receive adj, and when they do, they experience more chemotherapy-related toxicities.

Abstract
Objective: To investigate the clinical characteristics of extremely severe burn patients complicated with severe inhalation injury caused by dust explosion. Methods: The medical records of 13 extremely severe burn patients complicated with severe inhalation injury in August 2nd Kunshan factory aluminum dust explosion accident, who were admitted to the First Affiliated Hospital of Soochow University on August 2nd, 2014, were retrospectively analyzed. The following indicators were collected: (1) Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score and Sequential Organ Failure Assessment (SOFA) score at post admission hour (PAH) 24. (2) Prognosis, death time, causes of death, and the mortality of patients with different sexes. (3) The number of times of airway electronic bronchoscopy, airway characteristics, and the corresponding onset time. (4) The number and result of microorganism culture of lesion tissue during the leukoplakia formation stage. Detection of Pseudomonas aeruginosa in patients with and without leukoplakia in airway mucosa. Fisher's exact probability test was used to detect the mortality of patients with different sexes. Kappa test was used to detect the relevancy between leukoplakia and Pseudomonas aeruginosa. Results: (1) The APACHE Ⅱ score of patients of this group at PAH 24 was (19±3) points, and the SOFA score was (12±3) points. (2) Eight patients survived, while 5 patients died, and the time of death was 19-46 (34±10) d after injury. The main cause of death was multiple organ dysfunction syndrome, which was secondary to severe infection. One of the 7 male patients and 4 of the 6 female patients died, but there was no significantly statistical difference in mortality between patients of the two sexes (P>0.05). (3) Airway electronic bronchoscopy was performed 4-25 (10±5) times among patients of this group. Hyperemia and edema were found in the airway mucosa of all the 13 patients 2-3 weeks after injury; ulcer was found in the airway mucosa of 5 patients 2-4 weeks after injury; leukoplakia was found in the airway mucosa of 7 patients 4-14 weeks after injury; granulation formed in the airway mucosa of 7 patients 10-15 weeks after injury, and airway patency was affected, which was solved after local clamping or replacement of lengthened tracheal cannula. (4) During the leukoplakia formation stage, 19 cases of microorganism culture were performed basing on airway lesion tissue, and the results were 15 cases of Pseudomonas aeruginosa, 5 cases of Acinetobacter baumannii, 2 cases of Serratia marcescens, as well as 1 case of Stenotrophomonas maltophilia, Burkholderia cepacia, and Proteus mirabilis each. Among 7 patients with airway mucosa leukoplakia, 6 patients were detected with Pseudomonas aeruginosa. Among 6 patients without airway mucosa leukoplakia, 1 patient was detected with Pseudomonas aeruginosa. The appearance of leukoplakia was consistent with the detection of Pseudomonas aeruginosa (Kappa=0.69, P<0.05). Conclusions: Most of these extremely severe burn patients complicated with severe inhalation injury caused by dust explosion survived, and there was no significant gender difference in mortality. Electronic bronchoscopy showed that the early manifestations of airway mucosa were hyperemia and edema, followed by varying degrees of erosion, ulcer, leukoplakia, and granulation formation, etc. Leukoplakia may be relevant to Pseudomonas aeruginosa infection.

Abstract
OBJECTIVE To provide autonomy support from three dimensions based on self-determination theory (SDT), i.e. professional support, peer support, family support, and to investigate whether this intervention can improve diabetes self-management behavior and glycemic control of diabetic patients, and to analyze the influencing factors of the effect. METHODS Using convenient sampling method, three communities were selected respectively in Beijing. Each community selected health service stations with similar conditions as different intervention groups. The diabetic patients managed by the station who were eligible for inclusion were recruited into this intervention group. The community stations were divided into three groups. The routine intervention group only issued knowledge manuals and conducted health management according to the requirements of basic public health services. Peer support groups were divided into small groups and carried out doctor-led group activities. Based on doctor-led peer support activities, the doctors and peers were trained to provide autonomy support based on self-determination theory, and their family members were trained in the form of manuals to provide autonomy support, forming a concerted support of the three dimensions. Activity processes and materials were also designed based on SDT. The intervention duration was 3 months, and the main evaluation indexes were HbA1c and patients' self-management behaviors, skills, knowledge, and self-efficacy scores. RESULTS Before and after the intervention, the HbA1c of routine intervention group were 7.40%±1.37%, 7.30%±1.18%. The HbA1c of peer support group before and after the intervention were 7.33%±1.15% and 7.13%±1.27%. The HbA1c of autonomy support group before and after the intervention were 7.42%±1.22% and 6.78%±0.80%. Before and after the intervention, the self-management score in routine intervention group was 10.54±2.28 and 10.80±2.15, the score in peer support group was 11.09±1.89 and 11.40±1.78, the score in autonomy support group was 10.34±1.99 and 11.10±1.65, respectively. The HbA1c and self-management score increased higher in autonomy support group than in the other two groups. After intervention, the control rate in autonomy support group was higher than in the other two groups. According to the multi-factor analysis, the value of HbA1c after intervention was positively related to the baseline HbA1c, and negatively related to self-management behavior. The value in autonomy support group was higher than in routine intervention group. Baseline self-management behavior, self-efficacy, knowledge, skill, family support, autonomy support, peer support and age were positively correlated with the change of behavior. CONCLUSION self-management behavior intervention based on self-determination theory can effectively promote self-management behavior and glycemic control of diabetic patients, and the effect is better than single peer support activities.

Abstract
Objective: To discuss the correlation of permeability surface (PS) with hematoma and edema volume in acute spontaneous putaminal and thalamic hematoma using CT perfusion imaging. Methods: A total of 48 acute spontaneous putaminal and thalamic hemorrhage patients were enrolled in this study during October 2015 and December 2016 at the First Affiliated Hospital of Wenzhou Medical University. At the image slice with maximum size of hematoma, PS was measured by drawing various regions of interest (ROI) including"hot spots", perihematomal regions, outward regions, hemisphere regions and contralateral mirror regions. The relative PS (rPS) was calculated as the ratio of ipsilateral to contralateral PS value in each ROI. Hematoma and edema volumes were traced and obtained with commercial software. Results: The"hot spots"PS ((2.8±1.5) ml·100 g(-1)·min(-1)) and perihematomal PS ((2.1±1.4) ml·100 g(-1)·min(-1)) were both significantly higher than the PS of the contralateral mirror regions ((1.1±0.5) ml·100 g(-1)·min(-1)) (P<0.001). There was no significant difference in outward regions PS and contralateral mirror regions PS (P>0.05), nor in hemisphere regions PS and contralateral mirror regions PS (P>0.05). There was no significant difference in"hot spots"rPS and perihematomal rPS (P=0.218). The"hot spots"rPS and Perihematomal rPS were both higher than the rPS of the outward and hemisphere regions (P<0.01). There was no significant difference in the outward and hemisphere regions (P<0.01). The median hematoma volume was 12.63 ml and the median edema volume was 12.36 ml. The edema volume had a positive association with the hematoma volume(r=0.799, P<0.001) and perihematomal PS(r=0.465, P=0.001). Perihematomal PS had a positive association with the hematoma volume (r=0.386, P=0.007). Conclusion: The damage of blood-brain barrier around acute spontaneous hematoma can be measured via CT perfusion imaging. Perihematomal PS was associated with the hematoma and edema volume.

Abstract
Human infections with novel avian influenza A(H7N9)virus was an emerging infectious disease discovered in March, 2013. As of June30, 2016, 770 cases of H7N9 were reported in worldwide including 315 deaths with 40.9% of high case fatality rate. Yangtze River Delta and Pearl River Delta were the high-prevalence area. Formerly, the cases of H7N9 were concentrated on the municipalities. However, most of the case-patients were from smaller cities or rural areas nowadays. The H7N9 human infections mainly occurred in winter and spring every waves as similar as seasonal and H5N1 human infections. Middle aged and old (the median age was 61 years) male patients were occupied the large proportion among the cases of H7N9. In addition, the phenomenon of the limited and unsustained human-to-human transmission were existed. At present, the 4 major epidemic waves had happened and human infections with novel avian influenza A (H7N9) virus could be outbreak regularly in China. In this paper, the pathogenic characteristics and disease distribution of H7N9 influenza A viruses were elaborated, with both transmission factors and control measures, which were helpful to provide the scientific evidence for prevention and control in H7N9avian influenza epidemic.

Abstract
Objective: To investigate the change of cerebral microcirculation of chronic cerebral circulation insufficiency(CCCI) patients and the relationship between CCCI and crossed cerebellar diaschisis(CCD)by using 320-detector row of low-dose volume CT perfusion imaging. Methods: A total of 158 patients (103 males, 55 females, from 45 to 82 years old, the mean age was 62.9) with symptoms of CCCI were admitted to the First Affiliated Hospital of Wenzhou Medical University from June 2013 to January 2016. Low-dose CTP imaging of whole brain was performed to them using 320-detector row volume CT scanner. The perfusion parameters such as cerebral blood flow(CBF), cerebral blood volume(CBV), mean transit time(MTT), time to peak(TTP) and DLY in both cerebral blood supply areas and cerebellum were got, so were the 4-dimensional CTA images, and rCBF, rCBV, rMTT and rTTP were calculated by ipsilateral/contralateral value. Comparative t-test and independent t-test were applied to analyzing these parameters quantitatively.Chi-square test and Logistic regression model were applied to analyzing the related clinical risk factors. Results: (1) All 108 patients in CCCI group showed asymmetric perfusion within two cerebral hemispheres in CTP images. The CBF, CBV of diseased side were lower than the contralateral mirror area (t(CBF)=-12.89, t(CBV)=-7.031, P(CBF, CBV)<0.001); the MTT of the diseased side was shorter than the contralateral mirror area (t(MTT) =13.310, P(MTT)<0.001); the TTP of the diseased side was longer than the contralateral mirror area (t(TTP)=-4.012, P(TTP)<0.001). The rCBF and rCBV of CCCI group were lower than that in non-CCCI group (t(rCBF)=3.079, t(rCBV)=2.760, P(rCBF, rCBV)<0.01), while the rTTP of CCCI group was longer than that in non-CCCI group (t(rTTP)=4.846, P(rTTP)<0.001). (2)The results of Chi-square test showed that the differences of gender (χ(2)=4.036, P=0.045), hyperlipidemia (χ(2)=7.687, P=0.006), as well as smoking (χ(2)=11.868, P=0.001) had statistical significance between CCCI group and non-CCCI group.Multi-factor Logistic regression analysis showed that hyperlipidemia (OR value=3.736, P=0.016) and smoking (OR value=4.641, P=0.01) were the risk factors of CCCI, while gender had no relationship with it.(3)The incidence of CCD was 18.5% in the CCCI group, and at the same time, the supratentorial corresponding blood supply areas were classified.A total of 10(34.5%) cases were in blood supply area of posterior cerebral artery, 6(20.7%) cases were in blood supply area of middle cerebral artery, 12(41.4%) cases were of anterior cerebral artery, while only 1(3.5%) case was of basal ganglia, in which 4 cases were in blood supply area of posterior cerebral artery, another 4 cases were middle cerebral artery, 7 cases were of anterior cerebral artery and no case of basal ganglia respectively leading CCD alone. Conclusions: CTP could display the microcirculation situation of abnormal brain tissue perfusion area intuitively and quantitatively. Additionally, it could reflect the degree of relationship between cerebral several blood supply areas and cerebellum.

Abstract
Objective: To investigate the value of the endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in diagnosing mediastinal enlarged lymph nodes. Methods: A total of 210 patients with mediastinal enlarged lymph nodes from the First Affiliated Hospital of Zhengzhou University from 2014 July to 2015 October were enrolled for EBUS-TBNA. Endobronchial ultrasound (EBUS) imaging features, including lymph node short diameter, the ratio of longitudinal to transverse diameter, the blood flow and morphology destroy, in benign and malignant lymph nodes were evaluated separately and their relationships with the rate of malignant lymph nodes were also analyzed. The significant variables according to single factor analysis were brought into the Logistic multivariate analysis, which investigated the risk factors of malignant lymph nodes. The best cut-off point of the short diameter of lymph nodes was analyzed by receiver operating characteristic curve (ROC). The sensitivity, specificity and accuracy of EBUS-TBNA in the diagnosis of malignant lymph nodes were analyzed by the standard calculation formula. Results: The sensitivity, specificity, accuracy rate of EBUS-TBNA diagnosing lung cancer and other tumor with mediastinal lymph node metastasis were 91.2%, 100%, 93.8%. The rates of malignant in lymph node with short diameter ≥1.0 cm, ratio of longitudinal to transverse diameter<1.5, blood flow distribution Ⅱ-Ⅲ, morphology destroy by the EBUS measurement were higher than those in the lymph node with short diameter<1.0 cm, ratio of longitudinal to transverse diameter ≥ 1.5, the blood flow distribution 0-Ⅰ, without morphology destroy (79.8%, 77.8%, 84.7%, 76.7% vs 37.7%, 44.6%, 42.9%, 42.9%), and the four factors were independent risk factors for malignant lymph nodes (all P<0.001). The ROC curve indicated the optimal cut-off point of short diameter was 8.2 mm. The accuracy of diagnosis by the combination of the above 4 ultrasound features, those were the lymph node short diameter not less than 1 cm, the ratio of longitudinal to transverse diameter less than 1.5, the blood flow distribution Ⅱ-Ⅲ and morphology destroy, was higher than those of the single factor (89.3% vs 74.7%, 67.9%, 67.8%, 67.5%) (all P<0.001). Conclusion: EBUS-TBNA has satisfying value in diagnosing malignant mediastinal enlarged lymph nodes.

Abstract
Various nitric oxide (NO) regulators [including the NO donor sodium nitroprusside (SNP), the NO scavenger 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO), the NO-synthase inhibitor N (G)-nitro-L-Arg-methyl ester (L-NAME), and the SNP analogues sodium nitrite/nitrate and sodium ferrocyanide] were investigated to elucidate the role of NO in white clover (Trifolium repens L.) plants after long-term (5 days) exposure to cadmium (Cd). A dose of 100 μM Cd stress significantly restrained plant growth and decreased the concentrations of chlorophyll and NO in vivo, whereas it disrupted the balance of stress-related hormones and enhanced the accumulation of Cd, thereby inducing reactive oxygen species (ROS) burst. However, the inhibition of plant growth was relieved by 50 μM SNP through its stimulation of ROS-scavenging compounds (ascorbic acid, ascorbate peroxidase, catalase, glutathione reductase, non-protein thiol, superoxide dismutase, and total glutathione), regulation of H(+)-ATPase activity of proton pumps, and increasing jasmonic acid and proline but decreasing ethylene in plant tissues. Even so, the alleviating effect of SNP on plant growth was counteracted by cPTIO and L-NAME and was not observed with SNP analogues, suggesting that the protective roles of SNP are related to the induction of NO. These results suggest that NO may improve the Cd tolerance of white clover plants by eliminating oxidative damage, re-establishing ATPase activity, and maintaining hormone equilibrium. Improving our understanding of the role of NO in white clover plants is key to expanding the plantations to various regions and the recovery of pasture species in the future.
