Abstract
To investigate the role of co-stimulatory and co-inhibitory molecules on immune tolerance in immune thrombocytopenia (ITP), this study mapped the immune cell heterogeneity in the bone marrow of ITP at the single-cell level using Cytometry by Time of Flight (CyTOF). Thirty-six patients with ITP and nine healthy volunteers were enrolled in the study. As soluble immunomodulatory molecules, more sCD25 and sGalectin-9 were detected in ITP patients. On the cell surface, co-stimulatory molecules like ICOS and HVEM were observed to be upregulated in mainly central memory and effector T cells. In contrast, co-inhibitory molecules such as CTLA-4 were significantly reduced in Th1 and Th17 cell subsets. Taking a platelet count of 30×109 L-1 as the cutoff value, ITP patients with high and low platelet counts showed different T cell immune profiles. Antigen-presenting cells such as monocytes and B cells may regulate the activation of T cells through CTLA-4/CD86 and HVEM/BTLA interactions, respectively, and participate in the pathogenesis of ITP. In conclusion, the proteomic and soluble molecular profiles brought insight into the interaction and modulation of immune cells in the bone marrow of ITP. They may offer novel targets to develop personalized immunotherapies.

Abstract
Objective: The aim of this study was to evaluate the impact of neoadjuvant radiotherapy on anorectal function of patients with mid-low rectal cancer by means of high-resolution anorectal manometry. Methods: A retrospective observational study was conducted. Information on patients with mid-low rectal cancer was collected from the prospective registry database of Rectal Cancer at Peking Union Medical College Hospital (PUMCH) from June 2020 to April 2023. Anorectal functions were detected using three-dimensional high-resolution manometry system. Logistic regression analysis was performed to identify the factors associated with the changed anorectal manometry. Results: A total of 45 patients with mid-low rectal cancer were included in the study. Thirty-two (71.1%) patients were male, 13 (28.9%) patients were female. The mean age was 60±11 years, and the mean BMI was 23.4±3.7 kg/m2. The mean distance between the lower edge of the tumor and the anal verge was 5.4±1.5 cm. The median size of the tumor was 3.4 (2.9-4.5) cm, and the median circumferential extent of the tumor was 66.0 (45.5-75.0) %. 41 (81.1%) patients were MRI T3-4 and 40 (88.9%) patients were MRI N positive. The resting pressure has a decreasing trend after neoadjuvant radiotherapy (55.3±32.0 mmHg vs. 48.0±28.5 mmHg, t=1.930, P=0.060). There was no significant change in maximum squeezing and the length of the high-pressure zone after neoadjuvant radiotherapy. All volumes describing rectal sensitivity (first sensation, desire to defecate, and maximum tolerance) were lower after neoadjuvant radiotherapy. And maximum tolerance was significantly lower (66.0 [49.0,88.0] ml vs. 52.0 [39.0,73.5] ml, Z=-2.481,P=0.013). Univariate analysis demonstrated that the downstage of N-stage was associated with the decrease in maximum tolerance (OR=6.533, 95%CI:1.254-34.051, P=0.026). Conclusion: Neoadjuvant radiotherapy damages anorectal function by decreasing the resting pressure and rectal sensory threshold of patients. The N-stage downstaging was associated with a decrease in maximum tolerance.

Abstract
Objective: To analyze and summarize the clinical and pathological characteristics, management, and efficacy of patients with vulvar lichen sclerosus (VLS) through a single center large sample study, and preliminarily to explore the frequency of maintenance treatment medication for VLS. Methods: The clinical data of VLS patients in Obstetrics and Gynecology Hospital of Fudan University from 2018 to 2021 were retrospectively collected. The clinicopathological characteristics (patients' age, course of disease, complicated disease history, family history, symptoms, signs and pathology), treatment and effects were retrospectively analyzed. The patients in the maintenance treatment stage were followed up regularly to explore the minimum frequency of individual medication to maintain the stability of the disease. Results: (1) General situation: a total of 345 patients with VLS were included in this study. The average age was (50.4±14.7) years (ranged from 8 to 84 years old), prevalence was highest in the 50-59 years group (30.1%, 104/345). Immune diseases occurred in 18.6% (33/177) of patients, 24.3% (43/177) of patients had allergic skin diseases, and 5.6% (10/177) of the patients' immediate family members had chronic vulvar pruritus or vulvar hypopigmentation. (2) Clinical features: the most common symptom was vulvar pruritus (96.1%, 196/204) among 204 patients with recorded symptoms. The most common sign was hypopigmentation of the vulva (96.3%, 206/214). The most common involved sites were labia minora (70.3%, 142/202), labia majora (67.8%, 137/202), and labial sulcus (59.4%, 120/202). The cumulative number of sites involved in 62 vulvar atrophy patients (2.7±1.1) was significantly higher than that in 152 non-atrophy patients (2.2±1.0; t=3.48, P=0.001). The course of vulvar atrophy was (9.3±8.5) years, which was significantly longer than that of non-atrophy patients [(6.6±5.6) years; t=2.04, P=0.046]. (3) Pathological features: among the 286 patients with electronic pathological sections, the most common pathological feature in the epidermis was epithelial nail process passivation (71.3%, 204/286). The common pathological features in the dermis were interstitial collagenization (84.6%, 242/286), and inflammatory cell infiltration (73.8%, 211/286). (4) Treatment: 177 patients received standardized treatment after diagnosis and were followed up regularly in our hospital. In the initial treatment stage, 26.0% (46/177) of the patients were treated with 0.05% clobetasol propionate cream, and 74.0% (131/177) of the patients were treated with 0.1% mometasone furoate ointment. The complete remission rates of the two methods were respectively 80.4% (37/46) and 74.0% (97/131), and there was no statistically significant difference (χ²=0.76, P=0.385). During maintenance treatment, 27.1% (48/177) of the patients took the medication twice a week, 35.0% (62/177) took the medication once a week, and 37.9% (67/177) took the medication once every 10 days. During follow-up after 6 months of maintenance treatment, there were no patients with recurrence of pruritus or progression of vulvar signs. Conclusions: The majority of VLS patients have itching, hypopigmentation, involvement of labia minora and labia majora, progressive atrophy, and inflammatory infiltration of dermis. Local treatments of mometasone furoate and clobetasol propionate have good initial therapeutic effects. The frequency exploration of individualized maintenance treatment could minimize the occurrence of adverse reactions when ensuring the stability of the patients' condition.

Abstract
In recent years, precision medicine in various clinical disciplines has made great progress. However, the progress and practice of precision medicine in burn surgery at present have lagged far behind other disciplines due to various reasons including the solidification of concepts and the lack of effective methods and equipment. This article briefly expound the necessities and possible strategies of strengthening the construction and promotion of precision burn medicine system from the aspects of accurate diagnosis of burn wound area and depth, precise treatment of burn wounds, precise monitoring diagnosis and treatment of burn complications and scars, and precise rehabilitation treatment. In order to rapidly promote the development of precision burn medicine in our country, it is hoped that burn medical staffs will pay much more attention to this field, especially to conceptual transformation, development of innovative strategies, tools, and equipment for precise diagnosis and treatment of burn wounds and complications.

Abstract
BACKGROUND The sympathetic nerve is known to regulate immune responses in autoimmunity. Aberrant T cell immunity plays a vital role in immune thrombocytopenia (ITP) pathogenesis. The spleen is the primary site of platelet destruction. However, little is known whether and how splenic sympathetic innervation and neuroimmune modulation contribute to ITP pathogenesis. OBJECTIVES To determine the sympathetic distribution in the spleen of ITP mice and the association between splenic sympathetic nerves and T cell immunity in ITP development, and to evaluate the treatment potential of β2-adrenergic receptor (β2-AR) in ITP. METHODS Chemical sympathectomy was performed in an ITP mouse model with 6-hydroxydopamine and treated with β2-AR agonists to evaluate the effects of sympathetic denervation and activation. RESULTS Decreased sympathetic innervation in the spleen of ITP mice was observed. Significantly increased percentages of Th1 and Tc1 cells and reduced percentages of regulatory T cells (Tregs) were also observed in ITP mice with chemical sympathectomy (ITP-syx mice) relative to mice without sympathectomy (controls). Expression of genes associated with Th1, including IFN-γ and IRF8, was significantly upregulated, whereas genes associated with Tregs, including Foxp3 and CTLA4, were significantly downregulated in ITP-syx mice compared with controls. Furthermore, β2-AR restored the percentage of Tregs and increased platelet counts at days 7 and 14 in ITP mice. CONCLUSION Our findings indicate that decreased sympathetic distribution contributes to ITP pathogenesis by disturbing the homeostasis of T cells and that β2-AR agonists have potential as a novel treatment for ITP.

Abstract
Objective: To investigate the clinicopathological changes of early gastric cancer, especially its background mucosa, after the eradication of Helicobacter pylori (H. pylori), and to investigate the causes of underdiagnosis in preoperative biopsy pathology. Methods: Ninety cases of early gastric cancer after H. pylori eradication and 120 cases of endoscopic submucosal dissection (ESD) specimens without H. pylori eradication and their corresponding biopsy specimens were collected from Beijing Friendship Hospital Affiliated to Capital Medical University during 2016-2021. The clinicopathological data of the patients were analyzed, and the histopathological characteristics and immunophenotypic results compared. Results: Compared with the early gastric cancer without H. pylori eradication history, the histopathological type of early gastric cancer after H. pylori eradication was differentiated adenocarcinoma, with staggered distribution of cancerous and non-cancerous epithelium in the tumor area. The morphologic characteristics of gastric mucosa in the background of early gastric cancer after H. pylori eradication, were distinctive, including widening of the opening of enterosylated glandular ducts, serrated change of luminal margin, eosinophilic and microvesicular cytoplasm of enterosylated epithelium. Low-grade atypia existed in gastric cancer epithelial cells after sterilization, which might lead to underdiagnosis or missed diagnosis in biopsy pathology. Conclusions: Early gastric cancer and its background mucosa after H. pylori eradication have unique morphological characteristics, which can be used as a clue for pathological diagnosis, improve the accuracy of biopsy pathology and reduce the underdiagnosis.

Abstract
To investigate the relationship between serum uric acid to creatinine ratio (SUA/Cr) and metabolic syndrome (MS) and other indexes on physical examination population in Nantong area. Using the method of cross-sectional study, 8 148 physical examiners in the physical examination center of the Affiliated Hospital of Nantong University from January 2017 to April 2020 were used as the research objects, and the clinical data and serum biochemical indicators such as smoking and alcohol addiction, physical examination and so on were collected. According to the standard diagnosis of MS of Diabetes Society of Chinese Medical Association, the patients were grouped according to the quartile of SUA/Cr and the clinical data of each group were compared. Pearson correlation analysis and logistic regression analysis were used to explore the correlation between SUA/Cr and clinical indicators and the relationship between SUA/Cr and the risk of MS. The results showed that UA and SUA/Cr were the lowest in normal metabolism group, followed by abnormal metabolism group and the highest in MS group, The difference between the two groups was statistically significant (H=919.21 and 629.34, P<0.001). According to the SUA/Cr quartile, the population was divided into four groups. After adjusting for gender, age, smoking history and drinking history, SUA/Cr in group Q1 was positively correlated with BMI and TG (r=0.061 and 0.080, P<0.05), but negatively correlated with HDL-C (r=-0.057, P<0.05). Multivariate logistic regression results showed that after adjusting for age, sex, smoking history and drinking history, the risk of MS for BMI, SBP, DBP, FBG, TG, HDL-C and SUA/Cr [OR (95%CI)] were: 1.44 (1.41-1.47), 1.07 (1.06-1.07), 1.10 (1.10-1.11), 1.83 (1.73-1.92), 1.89 (1.79-1.99), 0.08 (0.06-0.10) and 1.54 (1.47-1.62). Compared with SUA/Cr group Q1, the risk of MS in group Q2, Q3 and Q4 increased by 75%, 162% and 346%, respectively. In conclusion, there was an independent positive correlation between SUA/Cr and MS risk in Nantong area.

Abstract
Objective: To explore the dynamic changes of Distress Thermometer scores and the relationship between psychological distress and quality of life in Chinese early breast cancer patients during chemotherapy. Methods: This prospective study enrolled 110 Chinese postoperative early breast cancer patients between March 2019 and December 2019. The psychological distress and quality of life (QOL) of patients were assessed by using the psychological distress management screening tool and the patient quality of life scale. Logistic regression model was used to analyze the influencing factors of psychological distress degree. The correlation between distress thermometer (DT) score changes and quality of life was analyzed by Pearson correlation analysis. Results: In total, 96 valid cases were analyzed. Before chemotherapy, 47 cases (49.0%) had DT score ≥4 points. After 2 cycles of chemotherapy, 40 cases (41.7%) had DT score ≥4 points. Thirty-four patients (35.4%) had DT score ≥4 points after chemotherapy. The DT score after chemotherapy was lower than that before chemotherapy and after 2 cycles of chemotherapy. Univariate analysis showed that income level and pathological stage were still significant related to the detection of DT score ≥4 points after chemotherapy (P<0.05). The changes of DT scores before and after chemotherapy were negatively correlated with the changes of quality of life ( r=-0.298, P=0.003). Conclusions: The detection rate of psychological distress in patients with early breast cancer during chemotherapy showed a decreasing trend. Income level and tumor stage are significant factors affecting the psychological distress of patients. There is a significant correlation between the psychological distress and the quality of life during chemotherapy. We should pay attention to the evaluation and monitoring state of psychological distress of patients during chemotherapy.

Abstract
The interplay between various symmetries and electronic bands topology is one of the core issues for topological quantum materials. Spontaneous magnetism, which leads to the breaking of time-reversal symmetry, has been proven to be a powerful approach to trigger various exotic topological phases. In this Letter, utilizing the combination of angle-resolved photoemission spectroscopy, magneto-optical Kerr effect microscopy, and first-principles calculations, we present the direct evidence on the realization of the long-sought spontaneous ferromagnetism induced topological transition in soft ferromagnetic EuB_{6}. Explicitly, we reveal the topological transition is from Z_{2}=1 topological insulator in paramagnetic state to χ=1 magnetic topological semimetal in low temperature ferromagnetic state. Our results demonstrate that the simple band structure near the Fermi level and rich topological phases make EuB_{6} an ideal platform to study the topological phase physics.

Abstract
The current study analyzed the morphologic features of macular ganglion cell complex (mGCC) thickness in optic pathway-related neuro-ophthalmic diseases by swept-source optical coherence tomography (SS-OCT). mGCC has the location diagnostic value similar to visual field, and the distribution of macular ganglion cells has accurate horizontal, vertical and quadrant characteristics. Specifically, prechiasmatic lesions showed atrophy and thinning of mGCC ring in single eye or mGCC atrophy in the upper and lower half of horizontal demarcation, chiasmatic lesions exhibited atrophy and thinning of mGCC in the half of bilateral nasal side demarcated by mid-vertical line, and retrochiasmatic lesions presented with atrophy of mGCC in the half of mid-vertical line demarcated or 1/4 quadrant. Therefore, the morphological characteristics of mGCC thickness are of value in the location diagnosis of optic path-related neuro-ophthalmic diseases.

Abstract
Objective: To examine the technique and effect of combined thoracic and abdominal organ clusters resection. Methods: From February 2019 to August 2021, totally 50 cases of combined thoracoabdominal organ cluster resection were completed at Transplant Medical Center, the Second Affiliated Hospital of Guangxi Medical University from donation after brain death donors. There were 47 males and 3 females, aging (34.8±12.3) years (range: 5 to 55 years). The length of hospital stay(M(IQR)) was 4(4) days (range: 2 to 43 days), the length of tube time was 4(2) days (range: 1 to 43 days). Through the midsternal incision and the abdominal grand cross incision, the cold perfusion was performing simultaneously when the perfusion lines of each target organ was established respectively. The combined resection was performed with the diaphragm as the boundary and the organ cluster as the unit. The heart and lung were separated on site and sent to the transplant hospital, and the abdominal organ cluster was directly preserved and returned to our hospital for further separation and repair. Results: Totaly 21 hearts, 47 pairs of lungs, 49 livers, 47 pairs of kidneys and 11 pancreas were harvested by this surgical treatment. The resection time was (32.6±6.5) minutes (range: 19 to 50 minutes), with no hot ischemia time. There was no accidental injury that affected organ quality and function. Heart transplantation was performed in 17 cases, combined heart-kidney transplantation in 2 cases, double lung transplantation in 43 cases, single lung transplantation in 6 cases, liver transplantation in 41 cases, combined liver-pancreas-duodenal cluster transplantation in 1 case, combined liver-kidney transplantation in 3 cases, combined pancreas-kidney transplantation in 9 cases, and kidney transplantation in 74 cases. Conclusion: Simultaneous perfusion and combined resection of thoracic and abdominal organ clusters for donation after brain death donors are feasible and effective.

Abstract
Objective: To compare the short-term and long-term outcomes between transanal total mesorectal excision (taTME) and laparoscopic total mesorectal excision (laTME) for mid-to-low rectal cancer and to evaluate the learning curve of taTME. Methods: This study was a retrospective cohort study. Firstly, consecutive patients undergoing total mesorectal excision who were registered in the prospective established database of Division of Colorectal Diseases, Department of General Surgery, Peking Union Medical College Hospital during July 2014 to June 2020 were recruited. The enrolled patients were divided into taTME and laTME group. The demographic data, clinical characteristics, neoadjuvant treatment, intraoperative and postoperative complications, pathological results and follow-up data were extracted from the database. The primary endpoint was the incidence of anastomotic leakage and the secondary endpoints included the 3-year disease-free survival (DFS) and the 3-year local recurrence rate. Independent t-test for comparison between groups of normally distributed measures; skewed measures were expressed as M (range). Categorical variables were expressed as examples (%) and the χ(2) or Fisher exact probability was used for comparison between groups. When comparing the incidence of anastomotic leakage, 5 variables including sex, BMI, clinical stage evaluated by MRI, distance from tumor to anal margin evaluated by MRI, and whether receiving neoadjuvant treatment were balanced by propensity score matching (PSM) to adjust confounders. Kaplan-Meier curve and Log-rank test were used to compare the DFS of two groups. Cox proportional hazard model was used to analyze and determine the independent risk factors affecting the DFS of patients with mid-low rectal cancer. Secondly, the data of consecutive patients undergoing taTME performed by the same surgical team (the trananal procedures were performed by the same main surgeon) from February 2017 to March 2021 were separately extracted and analyzed. The multidimensional cumulative sum (CUSUM) control chart was used to draw the learning curve of taTME. The outcomes of 'mature' taTME cases through learning curve were compared with laTME cases and the independent risk factors of DFS of 'mature' cases were also analyzed. Results: Two hundred and forty-three patients were eventually enrolled, including 182 undergoing laTME and 61 undergoing taTME. After PSM, both fifty-two patients were in laTME group and taTME group respectively, and patients of these two groups had comparable characteristics in sex, age, BMI, clinical tumor stage, distance from tumor to anal margin by MRI, mesorectal fasciae (MRF) and extramural vascular invasion (EMVI) by MRI and proportion of receiving neoadjuvant treatment. After PSM, as compared to laTME group, taTME group showed significantly longer operation time [(198.4±58.3) min vs. (147.9±47.3) min, t=-4.321, P<0.001], higher ratio of blood loss >100 ml during surgery [17.3% (9/52) vs. 0, P=0.003], higher incidence of anastomotic leakage [26.9% (14/52) vs. 3.8% (2/52), χ(2)=10.636, P=0.001] and higher morbidity of overall postoperative complications [55.8%(29/52) vs. 19.2% (10/52), χ(2)=14.810, P<0.001]. Total harvested lymph nodes and circumferential resection margin involvement were comparable between two groups (both P>0.05). The median follow-up for the whole group was 24 (1 to 72) months, with 4 cases lost, giving a follow-up rate of 98.4% (239/243). The laTME group had significantly better 3-year DFS than taTME group (83.9% vs. 73.0%, P=0.019), while the 3-year local recurrence rate was similar in two groups (1.7% vs. 3.6%, P=0.420). Multivariate analysis showed that and taTME surgery (HR=3.202, 95%CI: 1.592-6.441, P=0.001) the postoperative pathological staging of UICC stage II (HR=13.862, 95%CI:1.810-106.150, P=0.011), stage III (HR=8.705, 95%CI: 1.104-68.670, P=0.040) were independent risk factors for 3-year DFS. Analysis of taTME learning curve revealed that surgeons would cross over the learning stage after performing 28 cases. To compare the two groups excluding the cases within the learning stage, there was no significant difference between two groups after PSM no matter in the incidence of anastomotic leakage [taTME: 6.7%(1/15); laTME: 5.3% (2/38), P=1.000] or overall complications [taTME: 33.3%(5/15), laTME: 26.3%(10/38), P=0.737]. The taTME was still an independent risk factor of 3-year DFS only analyzing patients crossing over the learning stage (HR=5.351, 95%CI:1.666-17.192, P=0.005), and whether crossing over the learning stage was not the independent risk factor of 3-year DFS for mid-low rectal cancer patients undergoing taTME (HR=0.954, 95%CI:0.227-4.017, P=0.949). Conclusions: Compared with conventional laTME, taTME may increase the risk of anastomotic leakage and compromise the oncological outcomes. Performing taTME within the learning stage may significantly increase the risk of postoperative anastomotic leakage.

Abstract
Objective: To analyze the clinical and genetical characteristics of children with Gaucher disease and to explore the relationship between genotype and phenotype. Methods: In this retrospective study, the clinical data of 14 children with Gaucher disease diagnosed in Children's Hospital of Nanjing Medical University from August 2016 to October 2021 were analyzed. Their general conditions, clinical manifestations, laboratory tests and gene variations were collected, followed by the analysis of the clinical phenotypes and genotypes. Results: Among 14 children diagnosed with Gaucher disease, 9 were males and 5 were females, with the age of diagnosis ranging from 0.7 to 15.8 years. There were 10 patients with type 1 Gaucher disease, 2 patients with type 2, and 2 patients with type 3. The most common clinical manifestations were splenomegaly, thrombocytopenia (14 cases), hepatomegaly (8 cases) and anemia (8 cases). There were 6 patients with growth retardation, and 5 patients lag in height compared with their peers. Bone abnormalities were revealed by magnetic resonance imaging in 7 type 1 Gaucher disease patients, but only 1 patient experienced bone pain. Patients with type 2 and type 3 Gaucher disease also presented with convulsions, nystagmus and hearing loss. Gaucher cells were found in bone marrow smears in 12 patients. The glucocerebrosidase gene variations identified in 13 patients were heterozygous and in 1 type 1 patient was homozygous of L483P. L483P variation accounted for 33%(10/30) of the variation alleles, followed by V414L, D448H and R159W. The variation alleles were L483P and L422R, F252I and L483P in 2 children with severe neurological manifestations of Gaucher disease. A novel variation c.22A>G was detected. Conclusions: Splenomegaly and thrombocytopenia are the main clinical presentations of Gaucher disease in children and bone lesions revealed by radiologic imaging appear prior to the occurrence of bone diseases, type 2 and type 3 Gaucher disease also present growth retardation and neurological manifestation. The most frequent variant allele is L483P, which are detected in all 3 subtypes of Gaucher disease. The L422R, F252I gene variants correlated with the neuronopathic phenotype.

Abstract
Objective: To explore the incidence and risk factors of postoperative surgical site infection (SSI) after colon cancer surgery. Methods: A retrospective case-control study was performed. Patients diagnosed with colon cancer who underwent radical surgery between January 2016 and May 2021 were included, and demographic characteristics, comorbidities, laboratory tests, surgical data and postoperative complications were extracted from the specialized prospective database at Department of General Surgery, Peking Union Medical College Hospital. Case exclusion criteria: (1) simultaneously multiple primary colon cancer; (2) segmental resection, subtotal colectomy, or total colectomy; (3) patients undergoing colostomy/ileostomy during the operation or in the state of colostomy/ileostomy before the operation; (4) patients receiving natural orifice specimen extraction surgery or transvaginal colon surgery; (5) patients with the history of colectomy; (6) emergency operation due to intestinal obstruction, perforation and acute bleeding; (7) intestinal diversion operation; (8) benign lesions confirmed by postoperative pathology; (9) patients not following the colorectal clinical pathway of our department for intestinal preparation and antibiotic application. Univariate analysis and multivariate analysis were used to determine the risk factors of SSI after colon cancer surgery. Results: A total of 1291 patients were enrolled in the study. 94.3% (1217/1291) of cases received laparoscopic surgery. The incidence of overall SSI was 5.3% (69/1291). According to tumor location, the incidence of SSI in the right colon, transverse colon, left colon and sigmoid colon was 8.6% (40/465), 5.2% (11/213), 7.1% (7/98) and 2.1% (11/515) respectively. According to resection range, the incidence of SSI after right hemicolectomy, transverse colectomy, left hemicolectomy and sigmoid colectomy was 8.2% (48/588), 4.5% (2/44), 4.8% (8 /167) and 2.2% (11/492) respectively. Univariate analysis showed that preoperative BUN≥7.14 mmol/L, tumor site, resection range, intestinal anastomotic approach, postoperative diarrhea, anastomotic leakage, postoperative pneumonia, and anastomotic technique were related to SSI (all P<0.05). Multivariate analysis revealed that anastomotic leakage (OR=22.074, 95%CI: 6.172-78.953, P<0.001), pneumonia (OR=4.100, 95%CI: 1.546-10.869, P=0.005), intracorporeal anastomosis (OR=5.288, 95%CI: 2.919-9.577,P<0.001) were independent risk factors of SSI. Subgroup analysis showed that in right hemicolectomy, the incidence of SSI in intracorporeal anastomosis was 19.8% (32/162), which was significantly higher than that in extracorporeal anastomosis (3.8%, 16/426, χ(2)=40.064, P<0.001). In transverse colectomy [5.0% (2/40) vs. 0, χ(2)=0.210, P=1.000], left hemicolectomy [5.4% (8/148) vs. 0, χ(2)=1.079, P=0.599] and sigmoid colectomy [2.1% (10/482) vs. 10.0% (1/10), χ(2)=2.815, P=0.204], no significant differences of SSI incidence were found between intracorporeal anastomosis and extracorporeal anastomosis (all P>0.05). Conclusions: The incidence of SSI increases with the resection range from sigmoid colectomy to right hemicolectomy. Intracorporeal anastomosis and postoperative anastomotic leakage are independent risk factors of SSI. Attentions should be paid to the possibility of postoperative pneumonia and actively effective treatment measures should be carried out.

Abstract
Disposal of long-lived fission products (LLFPs) produced in reactors has been paid a lot attention for sustainable and clean nuclear energy. Although a few transmutation means have been proposed to address this issue, there are still scientific and/or engineering challenges to achieve efficient transmutation of LLFPs. In this study, we propose a novel concept of advanced nuclear energy system (ANES) for transmuting LLFPs efficiently without isotopic separation. The ANES comprises intense photoneutron source (PNS) and subcritical reactor, which consist of lead–bismuth (Pb-Bi) layer, beryllium (Be) layer, and fuel, LLFPs and shield assemblies. The PNS is produced by bombarding radioactive cesium and iodine target with a laser-Compton scattering (LCS) γ-ray beam. We investigate the effect of the ANES system layout on transmutation efficiency by Monte Carlo simulations. It is found that a proper combination of the Pb-Bi layer and the Be layer can increase the utilization efficiency of the PNS by a factor of ~ 10, which helps to decrease by almost the same factor the LCS γ-beam intensity required for driving the ANES. Supposing that the ANES operates over 20 years at a normal thermal power of 500 MWt, five LLFPs including 99Tc, 129I, 107Pd, 137Cs and 79Se could be transmuted by more than 30%. Their effective half-lives thus decrease drastically from ~ 106 to less than 102 years. It is suggested that this successful implementation of the ANES paves the avenue towards practical transmutation of LLFPs without isotopic separation.

Abstract
Trichinellosis is an important zoonotic parasitic disease worldwide and is principally caused by ingesting animal meat containing Trichinella infective larvae. Aspartyl aminopeptidase is an intracytoplasmic metalloproteinase that specifically hydrolyzes the N-terminus of polypeptides free of acidic amino acids (aspartic acid and glutamate), and plays an important role in the metabolism, growth and development of organisms. In this study, a novel T. spiralis aspartyl aminopeptidase (TsAAP) was cloned and expressed, and its biological properties and roles in worm growth and development were investigated. The results revealed that TsAAP transcription and expression in diverse T. spiralis stages were detected by RT-PCR and Western blotting, and primarily localized at cuticle, stichosome and intrauterine embryos of this nematode by immunofluorescence test. rTsAAP has the enzymatic activity of native AAP to hydrolyze the substrate H-Glu-pNA. There was a specific binding between rTsAAP and murine erythrocyte, and the binding site was localized in erythrocyte membrane proteins. Silencing of TsAAP gene by specific dsRNA significantly reduced the TsAAP expression, enzymatic activity, intestinal worm burdens and female fecundity. The results demonstrated that TsAAP participates in the growth, development and fecundity of T. spiralis and it might be a potential target molecule for anti-Trichinella vaccines.

Abstract
Objective: To analyze the cumulative reoperation rate of postoperative Crohn's disease (CD) patients and investigate the operation reasons and the effects of drugs on surgical recurrence. Method: Patients with Crohn's disease who had undergone intestinal resection from January 2000 to March 2020 in Peking Union Medical College Hospital were enrolled. Patients were divided into reoperation and non-reoperation group according to whether they had a second operation. And the basic characteristics and the reasons for the primary and second operation were retrospectively analyzed. Meanwhile, patients were divided into low-risk reoperation group and high-risk group based on risk stratification. Kaplan-Meier methods were performed to analyze the cumulative surgical recurrence rate and to compare the recurrence rate in different risk stratification and chi-square tests was used to analyze the effects of different maintenance drugs on reoperation. Result: A total of 160 patients were enrolled in the study. There were 110 males and 50 females, and the age at first operation was (35.6±14.1) years old. There were 40 patients in the reoperation group and 120 patients in the non-reoperation group. According to univariate analysis, the proportion of male gender(P=0.030), penetrating phenotype(P<0.001), history of appendectomy before the primary surgery(P=0.035) and no postoperative maintenance therapy (P<0.001) were higher in surgical recurrence group. In terms of the operation reasons, intestinal obstruction accounted for the highest proportion in the primary operation (26.9%, 43/160), while the intestinal fistula was the most common reason for reoperation (42.5%, 17/40). After the primary surgery, the cumulative reoperation rates at 1, 3, 5 and 10 years were 5.9% (9 cases), 12.3% (17 cases), 21.8% (25 cases) and 37.6% (34 cases), respectively. The ten years cumulative reoperation rate of the high-risk group was 42.8% (31 cases), which was much higher than that of low-risk group (19.8%, 3 cases), and the difference was statistically significant (P=0.006). There was no statistically significant difference in the surgical recurrence rate of low-risk group patients(P=0.076)whether maintenance therapies were added or not, while the recurrence rate of high-risk group patients who did not receive maintenance therapy was higher than those who received immunosuppressant with or without (±) 5-aminosalicylic acid (ASA) (P=0.001) and biological agent±5-ASA (P=0.001), and the difference was statistically significant. Conclusion: Patients with CD are still at risk of reoperation after surgery. Immunosuppressive agents and biologics can prevent patients from reoperation in high-risk groups.

Abstract
Objective: To systematically evaluate the clinical effect of anodized implants and sandblasted, large-grit, acid-etched (SLA) implants in the recent 10 years, so as to provide a reference for the selection and evaluation of implants. Methods: The data from Pubmed, Cochrane Library, Embase, CNKI, and Wanfang Data database from January 2010 to April 2020 were searched, to find clinical studies on anodized and SLA implants. According to the inclusion and exclusion criteria, literature was strictly screened, and data was extracted. Included studies were evaluated by using the methodological index for non-randomized studies (MINORS) and were analyzed by Stata14.0. The outcome of interest was cumulative survival rate (CSR) and marginal bone loss (MBL). Heterogeneity and publication bias among included literature was evaluated comprehensively. Results: A total of 22 articles, including 6 276 anodized implants, were collected for the analysis of anodized implants. Meta-analysis of proportions showed that anodized implants CSR were 98% (95%CI: 97%-98%, P<0.05) in total, at 5 years were 98% (95%CI: 98%-99%, P<0.05), and at 10 years were 97% (95%CI: 96%-98%, P<0.05). MBL change was 1.02 mm (95%CI: 0.69-1.34, P<0.05) in total. A total of 17 articles, including 4 567 SLA implants, were collected for the analysis of SLA implants. Meta-analysis of proportions showed that SLA implants CSR were 99% (95%CI: 98%-100%, P<0.05) in total, 99% at 5 years (95%CI: 98%-100%, P<0.05), and 99% at 10 years (95%CI: 97%-100%, P<0.05). MBL change was 0.69 mm (95%CI: 0.44-0.95, P<0.05) in total. The results of the above two studies were tested for bias (P>0.05), indicating no significant publication bias. Conclusions: Meta-analysis suggested that SLA implants have higher CSR and lower MBL than anodized implants.

Abstract
An UPLC-MS/MS method for rapid and simultaneous determination of psoralen, isopsoralen, apigenin, genistein, bavaisoflavone, neobavaisoflavone, bavachin, bavachinin, psoralenoside, and isopsoralenoside of Psoraleae Fructus in beagle dog plasma was established, and then the method was applied in the pharmacokinetic study after oral administration of Psoraleae Fructus extract to beagle dogs. The pharmacokinetic parameters were calculated by the software of WinNonlin. A Waters HSS-T3 column(2.1 mm×100 mm,1.8 μm)was used for liquid chromatography separation with acetonitrile-water(containing 0.004% formic acid) as the mobile phase for gradient elution.The mass spectrometry was detected using electrospray ion source(ESI) under multi-reaction monitoring mode(MRM), as well as positive ion mode.

Abstract
Objective: To evaluate the value of Hadad-Bassagasteguy flap (HBF) in endoscopic endonasal approaches (EEA) skull base reconstruction by radioanatomic measurements on CT of the skull base of Chinese adults. The following data in terms of anterior skull base defect and reconstruction, sphenoid platform area and middle skull base defect and reconstruction including sphenoid platform and sella area, clivus area defect and reconstruction, and HBF were collected and assessed. Methods: CT image data of 42 Chinese adults were selected to obtain radioanatomic measurement data related to HBF, anterior skull base defect and reconstruction, middle skull base defect and reconstruction, and defect and reconstruction of clivus area. SPSS 26.0 software was used to analyze the data. Results: The radioanatomic measurement data about HBF and skull base of 42 Chinese adults were obtained. The width of the leading edge of HBF [(37.49±2.86) mm] was 6 mm more than the anterior skull base width at the level of the anterior ethmoidal artery [(30.87±8.61) mm], and the width of the trailing edge of HBF [(42.61±3.95) mm] was also 6 mm more than the anterior skull base width at the level of the sphenoethmoidal junction [(26.79±2.79) mm]. The total length of HBF including the pedicle [(79.68±4.96) mm] was 6 mm more than the length of the anterior skull base reconstruction [(54.06±8.67) mm], and the length of HBF without pedicle [(46.27±3.14)] mm was 6 mm more than the length of anterior skull base defect [(30.87±8.61) mm]. The trailing edge width was 6 mm more than the planum sphenoidal width at the level of the optic strut [(30.87±8.61) mm]. The total length of HBF including the pedicle was 6 mm more than the length of the planum sphenoidal, and the sella reconstruction [(64.44±10.25) mm], also was 6 mm more than the length of the planum sphenoidal reconstruction [(73.61±8.28) mm]. The length of HBF without pedicle was 6 mm more than the length of the planum sphenoidal, and the sella defect [(27.88±3.74) mm], also was 6 mm more than the length of the planum sphenoidal defect [(15.50±3.38) mm]. The width of the leading edge of HBF and the width of the trailing edge were both 6 mm more than the width of clivus reconstruction at the level of the foramen lacerum [(21.68±2.30) mm]. The total length of HBF including pedicles was 6 mm more than the clivus reconstruction length [(67.09±5.44) mm], while the length of HBF without pedicles was also 6 mm more than the clivus defect length [(37.19±3.80) mm]. Conclusions: In this study, the radiosanatomic measurements ensured that HBF could provide sufficient tissue flap for the reconstruction of the anterior skull base and sphenoid plateau and extend the reconstruction area to sella and clivus. Preoperative radiosanatomic measurement can be used to predict the size of HBF required for skull base reconstruction, which provides important guidance for flap harvest.

Abstract
Objective: To investigate the clinicopathological characteristics and the therapeutic effects of signet ring cell carcinoma (SRCC) of rectum and sigmoid colon. Methods: Clinical data and the follow-up information of 29 SRCC patients treated in our tertiary care center from 2008 to 2018 were retrospectively reviewed. The clinicopathological features, diagnostic and therapeutic effects, and the prognostic outcomes were analyzed. Results: Among the 29 patients, 17 were male, 12 were female. The average age was (48.7±14.3) years. Colonoscopy revealed the features of diffuse circumferential thickening of the bowel wall in 20/29 cases (69.0%), while in 9/29 cases (31.0%), endoscopic biopsies showed false negative results. Twenty-five% (4/16) and 17.6% (3/17) lesions were misdiagnosed as the inflammatory changes by endoscopic rectal ultrasonography exam and rectal MRI scan, respectively. Thirteen of the 29 patients received the neoadjuvant chemoradiotherapy (NCRT), 27 patients underwent the radical resection surgeries, and 8 underwent the postoperative radiotherapy. With a median follow-up of 38.5 (3.5-87.0) months, the cumulative 3-years overall survival (OS) rate was 54.0%, and the cumulative 3-years disease-free survival (DFS) rate was 43.0%. The OS rates of patients treated with or without NCRT (non-NCRT) were 46.2% and 69.2%, respectively, without significant difference (P>0.05). The DFS rates of patients treated with or without NCRT were 45.8% and 39.2%, respectively, without significant difference (P>0.05). Parameters including age younger than 40 years and tumor size larger than 5 cm were independent potential risk factors for shortened OS (P<0.05). Conclusions: SRCC of the rectum and sigmoid colon is a rare malignant tumor with special clinical manifestations. It is younger-onset, highly malignant and with very poor prognosis. Therefore, in-depth researches with focus upon the progress of molecular oncology are urgently needed to substantially improve the therapeutic effect of this disease.

Abstract
In previous studies, a Trichinella spiralis serine protease (TsSP) was identified in excretion/secretion (ES) products from intestinal infective L1 larvae (IIL1) using immunoproteomics. The complete cDNA sequence of TsSP gene was 1372 bp, which encoded 429 amino acids with 47.55 kDa. The TsSP was transcribed and expressed at all T. spiralis life cycle phases, as well as mainly located at the cuticle and stichosome of the parasitic nematode. Recombinant TsSP bind to intestinal epithelial cells (IEC) and promoted larva invasion, however, its exact function in invasion, development and reproduction are still unknown. The aim of this study was to confirm the biological function of TsSP during T. spiralis invasion and growth using RNA interference (RNAi) technology. The results showed that on 1 day after electroporation using 2.5 µM siRNA156, TsSP mRNA and protein expression of muscle larvae (ML) was suppressed by 48.35 and 59.98%, respectively. Meanwhile, silencing of TsSP gene by RNAi resulted in a 61.38% decrease of serine protease activity of ML ES proteins, and a significant reduction of the in vitro and in vivo invasive capacity of IIL1 to intrude into the IEC monolayer and intestinal mucosa. When mice were infected with siRNA 156-transfected larvae, adult worm and muscle larva burdens were decreased by 58.85 and 60.48%, respectively. Moreover, intestinal worm growth and female fecundity were evidently inhibited after TsSP gene was knockdown, it was demonstrated that intestinal adults became smaller and the in vitro newborn larval yield of females obviously declined compared with the control siRNA group. The results indicated that knockdown of TsSP gene by RNAi significantly reduced the TsSP expression and enzymatic activity, impaired larvae intrusion and growth, and lowered the female reproductive capacity, further verified that TsSP might participate in diverse processes of T. spiralis life cycle, it will be a new prospective candidate molecular target of anti-Trichinella vaccines.

Abstract
Objective: To investigate the early clinical effects of home-based mobile health intervention on knee joint function after anterior cruciate ligament (ACL) reconstruction. Methods: This was a prospective randomized controlled trial. Patients undergoing arthroscopic ACL reconstruction alone at the Institute of Sports Medicine, Peking University Third Hospital from April 2019 to December 2019 were elected in the trial. Patients were divided into the intervention group and the control group according to random number method. The control group only received the guidance of the traditional paper rehabilitation schedule, while the intervention group also received personalized guidance of electronic rehabilitation prescription and follow-up notice delivered by a WeChat Mini Program Rehabilitation Cloud Platform in addition to the traditional guidance. Joint range of motion (ROM), visual analogue scale (VAS) and thigh circumference difference were assessed before and after the operation. Independent sample t test or Mann-Whitney U test was used for comparison of data between groups, and chi-square test was used for comparison of enumeration data. Results: One hundred and twenty five patients were enrolled in the trial, including 99 males and 26 females, with an average age of 29.0 years (range:18 to 45 years) and an average body mass index of 24.8 kg/m(2) (range:15.8 to 36.6 kg/m(2)). At 6 weeks, follow-up was available in 106 cases the target-reach rate of ROM in control group was 42.6%(23/54), which was 67.3%(35/52) in the intervention group, the difference was statistically significant (χ(2)=6.53, P=0.01); VAS of the intervention group was 2.5(2.0), lower than that of the control group 3.0(2.0)(M(Q(R))), the difference was statistically significant (Z=-2.06,P=0.04); And the thigh circumference difference of the intervention group was 2.0(2.0)cm lower than that of the control group 3.0(1.8)cm, the difference was statistically significant (Z=-3.00, P<0.01). Conclusion: Mobile health intervention can improve the early postoperative rehabilitation effect after ACL construction and the ROM of the knee joint, and reduce the bent-knee pain along with the thigh circumference difference.

Abstract
Macrophages have been reported to participate in inflammation, tissue homeostasis and tissue repair. The detailed mechanism of macrophage-mediated tissue repair is not clear. CXCL-10, secreted by monocytes, endothelial cells and fibroblasts, mediates immune response and angiogenesis by binding to CXCR3. In this study, the expression of CXCL-10 and CXCR3 in porcine lung injury induced by porcine reproductive and respiratory syndrome virus (PRRSV) infection was firstly examined. The results showed that the expression of both CXCL-10 and CXCR3 increased in the infected pig lungs. In addition, the increased expression of CXCL-10 and CXCR3 in macrophage treated by poly (I:C) was also observed, suggesting the autocrine system existed in macrophages. Furthermore, CXCL-10 treatment induced upregulation of Arg1 and VEGFa, and downregulation of TNFα in macrophage, and CXCR3 antagonist AMG487 treatment presented the contrary effects on the expression of Arg1, VEGFa, and TNFα. CXCL- 10-stimulated effects were dependent on PI3K/Akt signaling pathway. Wound-healing assay showed that CXCL-10 treatment macrophage conditioned medium promoted the healing process of endothelial cells. Our results suggested that CXCL-10/CXCR3 in macrophage may mediate tissue repair by regulating the macrophage expression of Arg1, VEGFa and TNFα. Modulation of CXCL-10/CXCR3 axis in macrophage may be a potential therapeutic strategy for tissue injury and repair.

Abstract
Objective: To analyze the metabolism of blood glucose and lipid in breast cancer patients after the first chemotherapy. Methods: Breast cancer patients who received chemotherapy for the first time from December 2016 to January 2020 were collected in our hospital, and their blood glucose and lipid levels were monitored. Patients were grouped according to different treatment plans. Non-parametric rank sum test was used for statistical analysis on SPSS software. Results: There were 1 356 female breast cancer patients were enrolled, blood glucose and lipid levels were compared before and after chemotherapy. Our results showed that baseline medium blood glucose was 5.2 mmol/L, lower than 5.3 mmol/L after chemotherapy (P<0.05). The baseline triglyceride (TG) was 1.2 mmol/L, lower than 1.6 mmol/L after chemotherapy (P<0.05). The baseline small dense low-density lipoprotein (sdLDL) was 0.7 mmol/L, lower than 0.8 mmol/L after chemotherapy (P<0.05). The baseline high density lipoprotein (HDL) was 1.3 mmol/L, higher than 1.2 mmol/L after chemotherapy (P<0.05). Patients' menstrual status and body mass index were related with blood glucose, TG, LDL and sdLDL (all P< 0.05). Conclusions: Abnormal metabolism of blood glucose and lipid are observed in breast cancer patients after the first chemotherapy. More awareness of cardiovascular disease in breast cancer patients might ensure their overall clinical benefits.

Abstract
Objective: To evaluate the performance of High-risk HPV typing detection in cervical cancer screening. Methods: A total of 3 231 women were recruited as the subjects of cervical cancer screening from Jiyuan city of Henan provinces from June to July 2017. All women underwent HPV DNA test. The women with cytological examination ≥ASCUS or cytological examination negative and HPV 16/18 positive underwent colposcopy biopsy and pathological examination. Pathological diagnosis was used as the gold standard. Sensitivity, specificity, positive predictive value (PPV), negative predictive value(NPV) as well as corresponding 95% confidence interval (CI) of HR-HPV and HPV 16/18 were calculated. Results: The mean age of 3 231 subjects selected in this study was 46.84±10.00 (21-64) years old. 524 subjects had the positive results of HR-HPV, including 91 of HPV16 and 15 of HPV18. Pathological test result CIN2+ was the gold standard. The sensitivity and specificity of HR-HPV for cervical precancer lesions screening were 93.75 (95%CI: 79.85-98.27) and 84.56% (95%CI: 83.26-85.77), respectively. To compared with HR-HPV, HPV16/18 had low sensitivity (65.63%, 95%CI: 48.31-79.59)and higher specificity (97.44%, 95%CI: 96.83-97.93). After age stratification by age 30 and 45, the sensitivity of HPV 16/18 was same with HR-HPV (100%, 95%CI: 34.24-100.00), the specificity of HPV 16/18 was higher than HR-HPV (98.71%, 95%CI: 96.27-99.56 vs 84.48%, 95%CI: 79.27-88.58) in<30 age group.The sensitivity of HR-HPVin 30-45 and ≥45 age group were higher than HPV16/18 (85.71%, 95%CI: 48.69-97.43 vs 71.43%, 95%CI: 35.89-91.78, 95.65%, 95%CI: 79.01-99.23 vs 60.87%, 95%CI: 40.79-77.84), but the specificity werelower than HPV16/18 (86.89%, 95%CI: 84.58-88.90 vs 98.51%, 95%CI: 97.51-99.11、83.49%, 95%CI: 81.81-85.04 vs 96.80%, 95%CI: 95.94-97.48). Conclusions: HR-HPV detection has relatively high sensitivity and specificity in cervical cancer screening. For >30 years old women, HR-HPV is more recommended in cervical cancer screening. Therefore, HR-HPV detection is an effective method for cervical cancer screening.

Abstract
Salivary microbiota is a typical habitat of the human microbiome. This study intended to use salivary microbiota as a model aiming to systematically address the influence of collection methods and temporal dynamics on the human microbiota compared to personal specificity. We carried out a supervised short-term longitudinal study to evaluate the influence of the change of collection methods and sampling time point on salivary microbiota in 10 systemically and orally healthy individuals with certain confounding factors (sex, oral and general health state, medication history, physical exercise, diet, and oral hygiene behavior) controlled before and during the sampling period. The microbial profiles were analyzed by 16S rDNA V3 to V4 hypervariable region amplicon sequencing. The taxonomic structure represented by the dominant species and the weighted UniFrac distance algorithm were used to demonstrate the individual specificity and the intraindividual variation introduced by the change of collection method and sampling time point. The findings suggested individual specificity existed in salivary microbiota from individuals with similar oral and general health status. The intraindividual variation brought by the change of collection method or sampling time point might introduce remarkable perturbation with the personal specificity. Insights into the intraindividual variation and personal specificity of salivary microbiota will enhance our understanding in salivary microbiota-related research. We recommend keeping collection conditions consistent within a study to avoid interference brought by the sampling. The strategy of repeated sampling at multiple time points as representative samples, as well as thorough interpretation of the complex relationships and causality between microbiome composition and disease without the interference of temporal dynamics, is optimal for research exploring the relationship between the salivary microbiome and disease.

Abstract
INTRODUCTION Gastric cancer is the fourth most common cancer in the world. By the time the patients are diagnosed with stage IV gastric cancer, many patients already have distant metastases. There is no unified systemic treatment plan in existence. The use of gastrectomy is ambiguous in patients with stage IV gastric cancer. The objective of this study was to evaluate the beneficial outcome of gastrectomy in patients with stage IV gastric cancer. METHODS Clinical information of patients with gastric cancer from 2000 to 2010 in the Surveillance, Epidemiology, and End Results database were extracted and analysed. The risk factors for stage IV gastric cancer were also analysed. RESULTS We observed that the median survival time for patients after surgery was greater than that for patients not treated surgically. The five-year survival rate for chemotherapy patients was higher than that of non-chemotherapeutic patients. Patients who receive both chemotherapy and surgery could achieve a more significant survival benefit. The risks following gastrectomy (partial, subtotal, hemi-) were lower than those of other surgical procedures, which provided guidance on the choice of surgical method. The numbers of regional lymph node metastasis were found to be related to prognosis. CONCLUSIONS In patients with stage IV gastric cancer, gastrectomy (partial, subtotal or hemi) should be selected when surgery is necessary. The number of regional lymph node metastasis could be considered as a prognostic factor for patients with stage IV gastric cancer and lymph node dissection could reduce the risk of patients undergoing surgery.

Abstract
Objective: This study aimed to evaluate the clinical performance of p16/Ki-67 dual staining for triage high risk HPV (HR-HPV) infected women. Method: Target objects were women who infected HR-HPV and received colposcopy examination between April and December of 2016 at the Second Affiliated Hospital of Zhengzhou University. Gynecologists collected the cervical exfoliated cells from eligible women for p16/Ki-67 dual staining, LBC testing and HPV DNA testing. Histology diagnosis were used as gold standard. Sensitivities, specificities, positive predictive values (PPVs), negative predictive values (NPVs) of p16/Ki-67 dual staining, LBC testing and HPV16/18 testing for triage of HR-HPV positive population were calculated and compared. Results: A total of 295 HR-HPV infected women were selected, and the mean age was (44.29±11.48) years old. Positive rates of p16/Ki-67 dual staining, HPV16/18 testing and LBC testing were 70.17% (207), 56.95% (168) and 85.76% (253), respectively. When CIN2+as the endpoint, among the three triage methods, sensitivity of p16/Ki-67 dual staining was 90.00% (95%CI: 85.06%-93.43%), higher than the value of HPV 16/18 testing, but lower than the value of LBC testing. Specificity, PPV and NPV of p16/Ki-67 dual staining were the highest [71.58% (95%CI: 61.81%-79.67%), 86.96% (95%CI:81.69%-90.88%) and 77.27% (95%CI: 67.49%-84.78%)]. When detection for CIN3+, sensitivity of p16/Ki-67 dual staining was 92.90% (95%CI: 87.74%-95.99%), lower than the value of LBC testing, but higher than the value of HPV16/18 testing. Specificity of p16/Ki-67 dual staining was 55.00% (95%CI: 46.74%-63.00%), lower than the value of HPV16/18 testing, but higher than the value of LBC testing. PPV of p16/Ki-67 dual staining was 69.57% (95%CI: 62.99%-75.43%), lower than the value of HPV 16/18 testing, but higher than the value of LBC testing. NPV of p16/Ki-67 dual staining was 87.50% (95%CI: 78.99%-92.87%), higher than value of HPV 16/18 testing, but lower than the value of LBC testing. Conclusion: p16/Ki-67 dual staining has better clinical effects than HPV 16/18 testing and LBC testing for triage women with HR-HPV infection.

Abstract
Objective: To evaluate the effectiveness of health belief model-based health education intervention in improving blood pressure control of patients with hypertension in community settings. Methods: From September 2016 to September 2017, 400 newly diagnosed patients with hypertension were recruited from 6 community healthcare centers with comparable population size and health services in the Shunyi District of Beijing. All community healthcare centers were randomly assigned to the intervention group (206 patients) and the control group (194 patients). Patients in the intervention group received 3 lectures (20-30 min for each) of health belief model-based health education. Patients in the control group received usual care. The basic characteristics, health beliefs, and health literacy were collected, and blood pressure was measured before and after the intervention, respectively. The difference-in-difference model was used to analyze the change of blood pressure and the influencing factors between two groups before and after the intervention. Results: A total of 134 patients in the intervention group and 129 patients in the control group completed the study. After adjusting for the age, gender, family income, medical insurance, chronic diseases and family history, the score of perceived barriers was increased by 1.65 (P=0.016), and perceived seriousness was decreased by 0.73 (P=0.018). The systolic blood pressure of patients was decreased by 7.37 mmHg (1 mmHg=0.133 kPa, P=0.001) and diastolic blood pressure was decreased by 4.07 mmHg (P=0.014), respectively. The β (95%CI) values were -7.37 (-11.88,-2.86) and -4.07 (-7.30, -0.84). The perceived susceptibility and self-efficacy had a significant influence on the blood pressure of patients (P<0.05). Conclusion: Health belief model-based health education intervention could significantly improve the blood pressure control of patients with hypertension in the community settings.

Abstract
Objective: The aim of the current study is to compare the short-term clinical outcomes between Billroth-I reconstruction using an overlap method and delta-shaped anastomosis in totally laparoscopic distal gastrectomy (TLDG). Method: A retrospective cohort study was performed. The following inclusion criteria were applied: (1) Preoperative gastroscopy and CT confirmed that the tumor is located in the antrum of the stomach, and the biopsy suggested adenocarcinoma; (2) Chest, abdomen and pelvis enhanced CT showed no evidence of distant metastasis; (3) Preoperative gastric reconstruction CT or endoscopic ultrasonography suggested that the clinical stage of the tumor is stage I-III. (4) During the operation, the tumor position was confirmed to be located in the antrum of the stomach by nanocarbon injection or gastroscope; (5) Complete laparoscopic radical gastrectomy for distal gastrectomy, and the gastrointestinal reconstruction was performed by delta-shaped anastomosis or overlap anastomosis. And the following exclusion criteria were applied: (1) History of gastric surgery; (2) Patients who cannot tolerate laparoscopic surgery because of comorbidities. Finally, data on 43 consecutive patients who underwent TLDG with Billroth-I reconstruction between January 2016 and November 2018 in Peking Union Medical College Hospital were retrospectively reviewed. Patients were divided into those who underwent Billroth-I reconstruction using an overlap method (n=20) or using delta-shaped anastomosis (n=23). The demographic and clinical characteristics and perioperative data of the two groups were analyzed. Measurement data that conformed to the normal distribution were expressed as the mean ± s, and differences between groups were compared using Student's t-test; comparisons between the counting data groups were performed using the χ(2) test or the continuously corrected χ(2) test. Results: The demographic and clinical characteristics were similar between the delta-shaped group and the overlap group (P>0.05). There was no significant difference between groups regarding operation time [(185.9±22.8) minutes vs. (184.0±25.8) minutes, t=0.260, P=0.796], blood loss [(50.9±36.0) ml vs. (47.0±30.8) ml, t=0.375, P=0.709], number of stapler reloads used for anastomosis (5.1±0.3 vs. 5.2±0.6, t=-0.465, P=0.651), time to flatus [(3.3±0.9) days vs. (3.6±0.9) days, t=-1.067, P=0.292) and postoperative hospitalization [(8.8±3.1) days vs. (10.4±3.8) days,t=-1.494, P=0.143]. As for the delta-shaped group and the overlap group, the anastomotic leakage rate was 4.3% (1/23) and 0 (χ(2)=0.000, P=1.000), respectively. The incidence of anastomotic bleeding was 4.3% (1/23) and 5.0% (1/20) (χ(2)=0.000, P=1.000), while the incidence of intra-abdominal hemorrhage was 4.3% (1/23) and 0 (χ(2)=0.000, P=1.000). The incidence of gastric emptying disorders was 4.3% (1/23) and 30.0% (6/20), respectively (χ(2)=3.454, P=0.063). All complications were cured after conservative treatment or symptomatic treatment. Conclusion: The overlap method for Billroth-I reconstruction is safe and feasible.

Abstract
Objective: To explore peptidomic changes of peptides in saliva and gingival crevicular fluid (GCF) before and after treatment of gingivitis. Methods: From January 2017 to September 2017, seventeen participants at the age of 24-62 (6 males and 11 females) at Department of Preventive Dentistry, Peking University School and Hospital of Stomatology with gingivitis were recruited in the present study. Their clinical parameters were measured and recorded. Saliva and GCF samples were collected from each of the participants at the baseline and 7 days after ultrasonic supragingival scaling, respectively. Matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF MS) was employed to detect the changes of peptidomic profiles, while ano-liquid chromatography-electrospray ionization-tandem mass spectrometry (nano-LC/ESI-MS/MS) was performed to identify the possible proteins from which the peptides might derive. Results: Initially, four peptide peaks [mass-to-charge ratio (m/z) values: 1 030.6, 1 043.4, 1 053.4 and 1 064.6] were screened out exhibiting a decreasing trend after treatment (P<0.05). Besides, five peptide peaks from gingival crevicular fluid (P<0.05) exhibited differential expression, among which 1 055.5 and 1 168.3 demonstrating a decrease after treatment, while 3 363.7, 3 480.9 and 3 489.5 increased overtime. Certain positive correlations were detected between some peptides and clinical parameters. Principle component analysis using the above mentioned peptide peaks showed a distinct distribution before and after treatment and peptides from GCF showed a slightly better capacity to discriminate patients before and after treatment. The peptides with m/z values of 1 055.5 in GCF and 1 064.6 in saliva were identified to be segments of serum albumin and complement C3, respectively. Conclusions: Several differentially expressed peptides were detected in saliva and GCF by MALDI-TOF MS, exhibiting the potentiality to act as biomarkers in gingivitis patients.

Abstract
Objective: To analyze the Clavien-Dindo classification of complications after right hemicolectomy and to explore the prognosis factors for postoperative complications. Methods: The retrospective case-control study was adopted. The clinical data of 176 patients who underwent right hemicolectomy at Department of General Surgery, Peking Union Medical College Hospital from October 2016 to February 2018 were collected. There were 95 male and 81 female patients with age of (62.4±12.7) years. The Clavien-Dindo classification was used for postoperative complications. Univariate and multivariate analysis were used to analyze the independent prognosis factors of complications after right colon resection. Results: Of the 176 patients, 2 patients had intraoperative complications (1.1%) and 39 patients had postoperative complications (22.2%), of which 10 cases had more than two complications, with a total of 53 complications. The proportions of Clavien-Dindo grade Ⅰ, Ⅱ, Ⅲ and Ⅳ complications were 41.5% (22/53), 49.1% (26/53), 7.5% (4/53), and 1.9%(1/53). Postoperative complications were associated with age, smoking history of the last 1 year, combined organ resection, lymph node dissection, intracorporeal anastomosis, and preoperative blood AST and Ca levels (all P<0.05). The results of multivariate analysis showed that intracorporeal anastomosis (OR=5.62, 95% CI: 2.46 to 12.85, P=0.00), preoperative blood AST (OR=-0.009, 95% CI: -0.018 to 0.000, P=0.04) and Ca (OR=0.51, 95% CI: 0.08 to 0.95, P=0.02) levels were independent prognosis factors affecting complications after right hemicolectomy. Conclusions: Complications of right hemicolectomy were mainly Clavien-Dindo grade Ⅰ and Ⅱ. Laparoscopic intracorporeal anastomosis should be carefully chosen, which may increase postoperative complications.

Abstract
Background Peri-procedural myocardial injury (PMI) during percutaneous coronary intervention (PCI) will result in an unfavorable clinical prognosis in patients, thus urgently necessitating effective drug treatment measures. Shen-Yuan-Dan (SYD) capsules are a traditional Chinese medicine (TCM) preparation that have been found to have potential myocardial protection effects during the peri-procedural phase of PCI in previous clinical and basic research; however, there is a lack of rigorous, randomized, and controlled studies. The aim of this study is to evaluate the efficacy and safety of SYD in decreasing PMI. Methods This is a randomized, double-blind, placebo-controlled clinical trial. A total of 284 patients with unstable angina will be randomized into test and control groups. The two groups will be given SYD or a placebo (three times each day, four capsules each time) 3 days before PCI on the basis of conventional treatment. Twelve hours before PCI, an additional 4 capsules will be given, and drug treatment is planned to be maintained for 1 month after surgery. Dynamic changes in the myocardial enzyme in four time-points (before PCI, and 4, 24, 48 hours after PCI) in both groups of patients that will be observed. The follow-up period will be 1 month. The primary observation markers are planned to evaluate the efficacy and safety of SYD in decreasing PMI. The secondary observation markers will be to evaluate the major adverse cardiovascular events (MACEs) status at day 30 after PCI, (all-cause mortality, non-fatal myocardial infarction, repeated revascularization of target blood vessel) and Seattle Angina Questionnaire scores. GRACE scores will be used for risk stratification, and the intervention efficacy of SYD on PMI patients with different risks will be retrospectively evaluated. Discussion This study will provide a rigorous clinical evidence to evaluate the efficacy and safety of SYD in decreasing PMI and the results are worth anticipating. Trial registration The design of this trial has been registered with the Chinese Clinical Trial Registry (No. ChiCTR-IPR-17011069).

Abstract
Objective: To explore the effect of unfavorable histological features on the clinical outcomes of patients receiving radical resection of colorectal cancer. Methods: A retrospective analysis of patients with colorectal cancer who received radical surgery between January 2013 and December 2015 at Department of General Surgery, Peking Union Medical College Hospital was performed. The impact of unfavorable histological features on the oncological outcomes of patients with lymph node-negative colorectal cancer were analyzed.A total of 167 patients were enrolled, including 98 males and 69 females with age of (63.6±11.6) years. Observation indicators included age, T stage, lymphovascular invasion, perineural invasion, tumor deposits, number of lymph node dissection, degree of differentiation, tissue type, and circumferential margin. Univariate analysis was performed with χ(2) test and multivariate analysis was performed with Cox regression model. Results: Univariate analysis showed that positive circumferential margins (CRM), tumor deposits and age were associated with disease free survival (DFS) rate; positive CRM, age, tumor deposits, and lymph nodes dissection less than 12 were significantly associated with overall survival (OS) rate (all P<0.05). Multivariate analysis showed that over 70 years of age (HR=1.053, 95% CI: 1.013 to 1.095, P=0.009), poorly differentiated adenocarcinoma (HR=7.572, 95%CI: 1.815 to 31.587, P=0.005), tumor deposits (HR=4.711, 95% CI: 1.809 to 12.264, P=0.002), mucinous adenocarcinoma (HR=3.063, 95% CI: 1.003 to 9.354, P=0.049), lymphovascular invasion (HR=2.885, 95% CI: 1.062 to 7.832, P=0.038), and nerve infiltration (HR=6.610, 95% CI: 1.037 to 42.122, P=0.046) were adverse prognostic factors of DFS rate; poorly differentiated adenocarcinoma (HR=12.200, 95% CI: 1.985 to 74.972, P=0.007), tumor nodules (HR=5.379, 95% CI: 1.636 to 17.685, P=0.006), over 70 years of age (HR=1.062, 95% CI: 1.013 to 1.114, P=0.013), and perineural invasion (HR=8.043, 95% CI: 1.026 to 63.055, P=0.047) were adverse prognostic factors of OS rate. There was no significant difference in the 3-year DFS rate and 3-year OS rate between T1-2 group and T3-4 group (P>0.05). Conclusion: Over 70 years of age, poorly differentiated adenocarcinoma, mucinous adenocarcinoma, tumor nodules, lymphovascular invasion, and perineural invasion are independent adverse prognostic factors of lymph node-negative colorectal cancer.

Abstract
Objectives: To analyze the biomechanical stability of four kinds of internal fixation for the type Ⅰ Hangman fracture, type Ⅱ odontoid fracture and the C(2/3) disc injury by finite element (FE) analysis. Methods: Thin-section spiral computed tomography (0.5 mm) was performed on C(1) to C(3) region of cervical vertebra in healthy male volunteers.A three-dimensional hexahedral FE model of upper cervical spine was established by software (Mimics, GEOMAGICS, Pro/E and Ansys). Then the weakening of the strength of grid was performed to simulate the FE model of the type Ⅰ Hangman fracture, type Ⅱ odontoid fracture and the C(2/3) disc injury (FE/Fracture), the four internal fixation models: anterior cervical plate+ odontoid screw+ cage (FE/ACP+ OS+ cage), affixing rods from pedicle screws in C(2) to lateral mass screws in C(3)+ odontoid screw + cage (FE/C(2)PS+ C(3)LMS+ OS+ cage), affixing rods from pedicle screws in C(1) to pedicle screws in C(2) and lateral mass screws in C(3) (FE/C(1)PS+ C(2)PS+ C(3)LMS), anterior odontoid screw plate fixation system (FE/AOSP) were simulated on the FE/Fracture model.Flexion, extension, lateral bending and axial rotation were imposed on the FE/Intact, FE/Fracture and the four fixation models respectively. Results: The intact model of upper cervical spine (C(1)-C(3)) was established successfully, consisting of 259 641 nodes and 403 674 units.There was no significant difference among the FE/ACP+ OS+ cage, the FE/ C(2)PS+ C(3)LMS+ OS+ cage and the FE/AOSP of ROMC(1/2).During flexion, extension, left axial rotation and right axial rotation of ROMC(2)-C(3), the FE/AOSP decreased 70.7%, 74.4%, 38.9%, 41.1% respectively compared with the FE/C(1)PS+ C(2)PS+ C(3)LMS.The ROMC(2)-C(3) during flexion, extension, left lateral bending, right lateral bending, left axial rotation and right axial rotation in the FE/AOSP decreased for 82.2%, 82.8%, 73.2%, 64.8%, 72.2%, 81.5% respectively when compared with those in FE/ACP+ OS+ cage.The ROMC(2)-C(3) during flexion, extension, left lateral bending, right lateral bending, left axial rotation and right axial rotation in the FE/AOSP decreased 88.2%, 81.2%, 47.6%, 41.2%, 38.9%, 39.0% respectively when compared with those in FE/C(2)PS+ C(3)LMS+ OS+ cage.The stress concentrated on the connection between plate and screw in the FE/ACP+ OS+ cage, the FE/C(2)PS+ C(3)LMS+ OS+ cage and the FE/C(1)PS+ C(2)PS+ C(3)LMS, while it distributed evenly in the FE/AOSP. Conclusion: Anterior odontoid screw plate fixation system can be used to treat the type Ⅰ Hangman fracture, type Ⅱ odontoid fracture, and the C(2/3) disc injury and can reserve the function of atlanto-axial joint.

Abstract
OBJECTIVE To explore mechanism of health beliefs by application of health belief model (HBM) and structural equation modeling (SEM) with regard to recreational physical activity (PA), to identify the differences of among population with high risk of chronic diseases and healthy people, and to provide the specific interventions of recreational physical activity and reference for health relevant policy-making in the future. METHODS A total of 2 736 residents with high risk of chronic diseases and 1 514 healthy people were involved. A questionnaire survey, physical examination and biochemical examination were conducted. The questionnaire based on HBM had acceptable validity and reliability. The proposed model based on the total sample size of the two groups was developed using the structural equation modeling and multi-comparison in the ways of appearance and parameters were also validated. RESULTS The median amount of recreational (PA) among population with high risk of chronic diseases and healthy people were 0.0 thousand-step equivalent with quartile of (0.0, 4.6) and 0.0 thousand-step equivalent with quartile of (0.0, 4.0) respectively. The results of SEM suggested that the direct effects of perceived objective barriers (β=-0.245), perceived subjective barriers (β=-0.057), cues to action (β=-0.043) and self-efficacy (β=0.117) on recreational (PA) were significant. Self-efficacy was the most important mediator. The multi-group comparisons indicated that the models of the two groups had the same appearance but the parameters between them were significant (δ χ2=27.4, P<0.05). The multi-group structural equation model (MSEM) indicated that two paths from cues to action and from perceived subjective barriers to recreational (PA) were not statistically significant among the population with high-risk of chronic diseases. In the two groups, one path coefficient from perceived objective barriers to subjective barriers (P=0.007) was statistically significant (P<0.05). CONCLUSION The recreational (PA) levels of both groups were lower. Health beliefs on recreational (PA) of the two groups played different roles and some paths were also different. Therefore, specific interventions and strategies should be developed for different people. For residents with high risk of chronic diseases, much more attention should be paid to reduce the objective and subjective barriers of recreational physical activity and to improve self-efficacy so as to delay or prevent the occurrence of chronic diseases and then to improve the quality of life of this kind of population.

Abstract
Gene engineering has attracted worldwide attention because of its ability of precise location of disease mutations in genome. As a new gene editing technology, clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9) system is simple, fast, and accurate to operate at a specific gene site. It overcomes the long-standing problem of conventional operation. At the same time, stem cells are a good foundation for establishing disease model in vitro. Therefore, it has great significance to combine stem cells with the rapidly developing gene manipulation techniques. In this review, we mainly focus on the mechanism of CRISPR/Cas9 technology and its application in stem cell genomic editing, so as to pave the way for promoting rapid application and development of CRISPR/Cas9 technology.

Abstract
Objective: To explore the expression of long noncoding RNA (lncRNA) HOXA11-AS in esophageal squamous cell carcinoma tissues and the relationship of HOXA11-AS level with clinical outcomes. Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to detect the expression level of HOXA11-AS in cell lines HET-1A, EC9706, EC109, and in tumor tissue and paired adjacent tissue samples from 73 ESCC patients who received surgical resection.The correlations of the expression level of HOXA11-AS with clinicopathological features and prognosis were also analyzed. Results: The relative expression levels of HOXA11-AS in tumor tissue and paired adjacent tissue were 0.832±0.387 and 2.486±1.087, respectively, with significant difference (P<0.001). The expression of HOXA11-AS was upregulated in 63.0%(46/73)ESCC tissues. The relative expression levels of HOXA11-AS in HET-1A, EC-9706 and EC-109 cells were 1.000, 23.553±3.221 and 17.217±1.968, respectively. The expression level of HOXA11-AS was upregulated in ESCC cell lines (P<0.001). High expression level of HOXA11-AS was correlated with histological grade and lymph node metastasis of ESCC patients (P<0.05). However, it was not associated with the age, gender, depth of infiltration and TNM staging (P>0.05). The median overall survival (OS) and median disease-free survival (DFS) of patients with low HOXA11-AS expression were 43 months and 42 months, respectively, significantly longer than 37 months and 28 months of patients with HOXA11-AS high expression (P<0.05). Cox model multivariate analysis showed that the expression of HOXA11-AS and lymph node metastasis were independent factors of poor prognosis of ESCC patients. Conclusions: The expression of HOXA11-AS is upregulated in esophageal cancer cell lines and tissues. High expression of HOXA11-AS is associated with poor prognosis of ESCC patients.Therefore, LncRNA HOXA11-AS may serve as a predictive marker of postoperative ESCC patients.

Abstract
Objective:IgG4-related disease is a newly recognized systemic disease, and its elucidation is progressing. However, little is known about its sinonasal manifestations.The aim of this study was to assess the olfaction of patients with IgG4-related disease.Method:Twenty-two patients with IgG4-related disease underwent the odor stick identification test to measure olfactory function.We analyzed the clinical features, including serum IgG4 levels, involved organs, and sinonasal computed tomography scores to explore the etiology of olfactory dysfunction.Result:Eleven patients with IgG4-related disease were found to have olfactory dysfunction. There were no differences in the clinical features between the olfactory dysfunction group and the normal group.Conclusion:There were no correlation between olfactory function and serum IgG4 level, involved organs or sinonasal computed tomography scores.We found that the prevalence of olfactory dysfunction was high in patients with IgG4-related disease and that it could be reversed.Olfactory dysfunction appears to be a novel important manifestation of IgG4-related disease.

Abstract
Bumetanide is a selective inhibitor of the Na+-K+-Cl--co-transporter 1(NKCC1). We studied whether bumetanide could affect axonal growth and behavioral outcome in stroke rats. Adult male Wistar rats were randomly assigned to four groups: sham-operated rats treated with vehicle or bumetanide, and ischemic rats treated with vehicle or bumetanide. Endothelin-1 was used to induce focal cerebral ischemia. Bumetanide administration (i.c.v.) started on postoperative day 7 and continued for 3 weeks. Biotinylated dextran amine (BDA) was injected into the right imotor cortex on postoperative day 14 to trace corticospinal tract (CST) fibers sprouting into the denervated cervical spinal cord. Nogo-A, NKCC1, KCC2 and BDNF in the perilesional cortex and BDA, PSD-95 and vGlut1 in the denervated spinal cord were measured by immunohistochemistry and/or Western blot. Behavioral outcome of rats was assessed by the beam walking and cylinder tests. The total length of CST fibers sprouting into the denervated cervical spinal cord significantly increased after stroke and bumetanide further increased this sprouting. Bumetanide treatment also decreased the expressions of NKCC1 and Nogo-A, increased the expressions of KCC2 and BDNF in the perilesional cortex and enhanced the synaptic plasticity in the denervated cervical spinal cord after cerebral ischemia. The behavioral performance of ischemic rats was significantly improved by bumetanide. In conclusion, bumetanide promoted post-stroke axonal sprouting together accompanied by an improved behavioral outcome possibly through restoring and maintaining neuronal chloride homeostasis and creating a recovery-promoting microenvironment by overcoming the axonal growth inhibition encountered after cerebral ischemia in rats.

Abstract
Objective: Arenavirus is a negative single-stranded RNA virus and an important human pathogen, mainly harbored and transmitted by rodents, causing severe diseases, including hemorrhagic fever and encephalitis. Following the discovery of a novel pathogenic arenavirus (Wenzhou virus, WENV), the prevalence of WENV in local small rodents was investigated. Methods: By using RT-PCR, WENV was screened in 48 and 156 rodents sampled from Wenzhou and Longquan, respectively. Results: Consequently, WENV was detected in 5 (10.41%) rodents sampled from Wenzhou. However, no WENV was identified in all the rodents sampled from Longquan. Genetic analysis of complete genome sequences indicated that 4 of 5 virus strains were closely related to the known Wenzhou viruses with high homology. Especially, the L and S segments of Wencheng-Rn-288 strain shared homology of 87.5% and 91.6% with other viruses, respectively. They formed a distinct lineage, suggesting that this strain might be a novel variant of WENV. Conclusions: Our results indicate that WENV has a high prevalence and high genetic diversity among rodents in Wenzhou. As the respiratory disease caused by WENV has been detected in Cambodia, it is necessary to strengthen the surveillance for WENV in China.

Abstract
Objective: Through systematically reviewing the reliability and validity of depression scales of Chinese version in adults in China to evaluate the psychometric properties of depression scales for different groups. Methods: Eligible studies published before 6 May 2016 were retrieved from the following database: CNKI, Wanfang, PubMed and Embase. The HSROC model of the diagnostic test accuracy (DTA) for Meta-analysis was used to calculate the pooled sensitivity and specificity of the PHQ-9. Results: A total of 44 papers evaluating the performance of depression scales were included. Results showed that the reliability and validity of the common depression scales were eligible, including the Beck depression inventory (BDI), the Hamilton depression scale (HAMD), the center epidemiological studies depression scale (CES-D), the patient health questionnaire (PHQ) and the Geriatric depression scale (GDS). The Cronbach' s coefficient of most tools were larger than 0.8, while the test-retest reliability and split-half reliability were larger than 0.7, indicating good internal consistency and stability. The criterion validity, convergent validity, discrimination validity and screening validity were acceptable though different cut-off points were recommended by different studies. The pooled sensitivity of the 11 studies evaluating PHQ-9 was 0.88 (95%CI: 0.85-0.91) while the pooled specificity was 0.89 (95%CI: 0.82-0.94), which demonstrated the applicability of PHQ-9 in screening depression. Conclusion: The reliability and validity of different depression scales of Chinese version are acceptable. The characteristics of different tools and study population should be taken into consideration when choosing a specific scale.
