Abstract
The investigation of the pathophysiological mechanisms and potential applications of impaired ventilatory efficiency in cardiopulmonary exercise testing has received considerable attention in the field of chronic obstructive pulmonary disease (COPD) research worldwide. A growing body of evidence supports the notion that impaired ventilatory efficiency is an important indicator of exertional dyspnea, reduced exercise capacity, and mortality in patients with COPD. As a result, ventilatory efficiency is emerging as a promising therapeutic target for alleviating dyspnea in COPD patients. This review aims to provide a comprehensive summary of the research progress into impaired ventilatory efficiency in patients with COPD. The primary objective of this review is to improve the understanding of COPD patients with impaired ventilatory efficiency, with the ultimate goal of facilitating the comprehensive assessment and management of COPD.

Abstract
Chronic Cerebral Hypoperfusion (CCH) is associated with cognitive dysfunction, the underlying mechanisms of which remain elusive, hindering the development of effective therapeutic approaches. In this study, we employed an established CCH animal model to delve into neuropathological alterations like oxidative stress, inflammation, neurotransmitter synthesis deficits, and other morphological alterations. Our findings revealed that while the number of neurons remained unchanged, there was a significant reduction in neuronal fibers post-CCH, as evidenced by microtubule-associated protein 2 (MAP2) staining. Moreover, myelin basic protein (MBP) staining showed exacerbated demyelination of neuronal fibers. Furthermore, we observed increased neuroinflammation, proliferation, and activation of astrocytes and microglia, as well as synaptic loss and microglial-mediated synapse engulfment post-CCH. Utilizing RNA sequencing, differential expression analysis displayed alterations in both mRNAs and circRNAs. Following gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses, both showed significant enrichment in immunological and inflammation-related terms and pathways. Importantly, the differentially expressed circular RNAs (DE circRNAs) exhibited a notable coexpression pattern with DE mRNAs. The ternary circRNA-miRNA-mRNA competing endogenous RNAs (ceRNA) network was constructed, and subsequent analysis reiterated the significance of neuroimmunological and neuroinflammatory dysfunction in CCH-induced neuropathological changes and cognitive dysfunction. This study underscores the potential role of circRNAs in these processes, suggesting them as promising therapeutic targets to mitigate the detrimental effects of CCH.

Abstract
Pre-chronic obstructive pulmonary disease (Pre-COPD) refers to individuals with chronic respiratory symptoms, structural abnormalities, and/or functional abnormalities, in the absence of airflow limitation, who may develop persistent airflow limitation over time. COPD is characterized by high prevalence and great heterogeneity and complexity. Early multidimensional identification and promotion of early prevention, management and treatment of Pre-COPD can help delay or halt the development of COPD, which has significant public health implications. This review aimed to summarize the definition, relevant cohorts, clinical trials, and other research progress in pre-COPD in order to improve the understanding of individuals with pre-COPD and improve early prevention and management of COPD.

Abstract
Objective: To examine the feasibility and technical considerations of thorough debridement using uniportal thoracoscopic surgery for tuberculous empyema complicated by chest wall tuberculosis. Methods: A retrospective analysis was conducted on 38 patients who underwent comprehensive uniportal thoracoscopy debridement for empyema complicated by chest wall tuberculosis in the Department of Thoracic Surgery, Shanghai Pulmonary Hospital, from March 2019 to August 2021. There were 23 males and 15 females, aged (M(IQR)) 30 (25) years (range: 18 to 78 years). The patients were cleared of chest wall tuberculosis under general anesthesia and underwent an incision through the intercostal sinus, followed by the whole fiberboard decortication method. Chest tube drainage was used for pleural cavity disease and negative pressure drainage for chest wall tuberculosis with SB tube, and without muscle flap filling and pressure bandaging. If there was no air leakage, the chest tube was removed first, followed by the removal of the SB tube after 2 to 7 days if there was no obvious residual cavity on the CT scan. The patients were followed up in outpatient clinics and by telephone until October 2022. Results: The operation time was 2.0 (1.5) h (range: 1 to 5 h), and blood loss during the operation was 100 (175) ml (range: 100 to 1 200 ml). The most common postoperative complication was prolonged air leak, with an incidence rate of 81.6% (31/38). The postoperative drainage time of the chest tube was 14 (12) days (range: 2 to 31 days) and the postoperative drainage time of the SB tube was 21 (14) days (range: 4 to 40 days). The follow-up time was 25 (11) months (range: 13 to 42 months). All patients had primary healing of their incisions and there was no tuberculosis recurrence during the follow-up period. Conclusion: Uniportal thoracoscopic thorough debridement combined with postoperative standardized antituberculosis treatment is safe and feasible for the treatment of tuberculous empyema with chest wall tuberculosis, which could achieve a good long-term recovery effect.

Abstract
Objective: To analyze the ultrasonic manifestations, clinical features, high risk factors and key points of pregnancy management in prenatal diagnosis of umbilical artery thrombosis (UAT). Methods: The data of 31 pregnant women of UAT diagnosed by prenatal ultrasonography and confirmed after birth from July 2017 to July 2022 at the Women's Hospital, Zhejiang University School of Medicine were retrospectively analyzed, including the maternal characteristics, pregnancy outcomes and fetal complications. In addition, the baseline data and pregnancy outcomes were compared in 21 patients who continued pregnancy after diagnosis of UAT. Of the 21 UAT cases that continued pregnancy, 10 cases were treated with low molecular weight heparin (LMWH; LMWH treatment group), while the other 11 patients had expectant treatment(expectant treatment group). Results: The age of the 31 pregnant women was (30.2±4.7) years, of which 5 cases (16%,5/31) were advanced age pregnant women. The gestational age at diagnosis was (32.9±4.0) weeks, and the gestational age at termination of pregnancy was (35.6±2.9) weeks. In 31 fetuses with UAT, 15 cases (48%) had fetal distress, 11 cases (35%) had fetal growth restriction, and 3 cases (10%) had intrauterine stillbirth. There were 28 cases of live births, including 26 cases by cesarean section and 2 cases by vaginal delivery. There were also 3 stillbirths, all delivered vaginally. Four neonates had mild asphyxia and two newborns had severe asphyxia. Among the 31 cases, 10 cases were terminated immediately after diagnosis, the gestational age at diagnosis was (35.9±2.9) weeks. Another 21 pregnancies continued, and their gestational age at diagnosis was (31.4±3.7) weeks. The median prolonged gestational age in LMWH treatment group was 7.9 weeks (4.6-9.4 weeks), and all were live births. The median prolonged gestational age in the expectant treatment group was 0.6 weeks (0.0-1.0 weeks), and 2 cases were stillbirths. There was a statistically significant difference in prolonged gestational age (P=0.002). Conclusions: Ultrasound is the preferred method for prenatal detection of UAT. Clinicians need to be vigilant for UAT when a newly identified single umbilical artery is detected by ultrasound in the second or third trimesters. The decision to continue or terminate the pregnancy depends on the gestational age and the condition of fetus. Attention should be paid to fetal movements as the pregnancy continues. The treatment of LMWH as soon as possible after diagnosis of UAT may improve the pregnancy outcome.

Abstract
Objective: We analyze the characteristics of Clostridioides difficile (C. difficile) infection among diarrhea patients in Kunming from 2018 to 2020 and provide evidence for follow-up surveillance and prevention. Methods: A total of 388 fecal samples of diarrhea patients from four sentinel hospitals in Yunnan Province from 2018 to 2020 were collected. Real-time quantitative PCR was used to detect the fecal toxin genes of C. difficile. The positive fecal samples isolated the bacteria, and isolates were identified by mass spectrometry. The genomic DNA of the strains was extracted for multi-locus sequence typing (MLST). The fecal toxin, strain isolation, and clinical patient characteristics, including co-infection with other pathogens, were analyzed. Results: Among the 388 fecal samples, 47 samples with positive reference genes of C. difficile were positive, with a total positive rate of 12.11%. There were 4 (8.51%) non-toxigenic and 43 (91.49%) toxigenic ones. A total of 18 strains C. difficile were isolated from 47 positive specimens, and the isolation rate of positive specimens was 38.30%. Among them, 14 strains were positive for tcdA, tcdB, tcdC, tcdR, and tcdE. All 18 strains of C. difficile were negative for binary toxins. The MLST results showed 10 sequence types (ST), including 5 strains of ST37, accounting for 27.78%; 2 strains of ST129, ST3, ST54, and ST2, respectively; and 1 strain of ST35, ST532, ST48, ST27, and ST39, respectively. Fecal toxin gene positive (tcdB+) results were statistically associated with the patient's age group and with or without fever before the visit; positive isolates were only statistically associated with the patient's age group. In addition, some C. difficile patients have co-infection with other diarrhea-related viruses. Conclusions: The infection of C. difficile in diarrhea patients in Kunming is mostly toxigenic strains, and the high diversity of strains was identified using the MLST method. Therefore, the surveillance and prevention of C. difficile should be strengthened.

Abstract
Objective: To study the impact of regional positive lymph node ratio (LNR) on prognosis of patients with gallbladder carcinoma. Methods: The clinicopathological and survival data of 53 patients with gallbladder carcinoma who underwent radical resection with regional lymph node metastasis in Ningbo University Affiliated Lihuili Hospital from May 2012 to December 2020 were collected, and receiver operating characteristic curve (ROC) was used to determine the optimal cut-off value of LNR for predicting postoperative survival status in patients with gallbladder carcinoma. According to the critical value, the patients were divided into low LNR group and high LNR group. The clinicopathological features and prognosis of the two groups were compared. Log rank test was used for univariate analysis of prognostic factors in patients with gallbladder carcinoma, and Cox proportional hazards model was used for multivariate analysis. Results: A total of 417 regional lymph nodes were dissected in 53 patients, of which 144 lymph nodes were positive, with a positive rate of 34.5%. The optimal cut-off value of LNR for predicting postoperative survival status of patients with gallbladder carcinoma was 0.33. According to this cut-off value, patients were divided into low LNR group (LNR≤0.33, 28 cases) and high LNR group (LNR>0.33, 25 cases). The recurrence rates were 64.3% (18/28) and 88.0 % (22/25) in low LNR group and high LNR group, respectively. The median recurrence-free survival (RFS) was 8 and 7 months, respectively (P=0.032). In the low LNR group, the 1-, 3-, and 5-year survival rates were 56.2%, 38.4%, and 32.0%, respectively, and the median overall survival (OS) was 16 months. In the high LNR group, the 1-, 3-, and 5-year survival rates were 37.9%, 5.4%, and 0, respectively, and the median OS was 9 months. The postoperative survival rate of patients in the low LNR group was better than that in the high LNR group (P=0.008). Univariate analysis showed that LNR was even associated with RFS and OS in patients with gallbladder carcinoma (P<0.05). Multivariate analysis showed that LNR>0.33 was an independent risk factor for postoperative RFS (HR=1.977, 95% CI: 1.045-3.740), but not for OS (HR=1.561, 95% CI: 0.685-3.553). Conclusion: On the basis of clearing a sufficient number of regional lymph nodes, patients with gallbladder carcinoma with regional LNR>0.33 are more likely to relapse after operation, but the predictive value of LNR>0.33 OS is insufficient.

Abstract
Preserved ratio impaired spirometry (PRISm) refers to the mode of a decrease in forced expiratory volume in 1 second (FEV1) while the FEV1/forced vital capacity (FVC) remains constant. PRISm was prevalent in the study population, but it is underreported in the current research. The cohort studies in European-American have found that the PRISm has a higher risk of developing chronic obstructive pulmonary disease (COPD), cardiovascular-related deaths and all-causes death than the normal lung function. PRISm may be one of the pre-COPD population, so early detection and prevention are crucial. In this review, we summarized the recent advances in the research of PRISm with the aim to increase understanding of PRISm, and to provide comprehensive evaluation and management for PRISm population.

Abstract
Objective: To explore the clinical effects of pulsed dye laser (PDL) dynamically combined with triamcinolone acetonide (TAC) in the treatment of keloids. Methods: A retrospectively observational study was conducted. From April 2015 to October 2020, 34 keloid patients (46 keloids) who met the inclusion criteria were admitted to Huaihe Hospital of Henan University. The patients were divided into TAC group and dynamic treatment group according to their treatment methods. There were 18 patients (26 keloids) in TAC group, including 8 males and 10 females, aged (30±12) years, who were treated with TAC injection alone. There were 16 patients (20 keloids) in dynamic treatment group, including 6 males and 10 females, aged (26±11) years, who were treated with TAC injection, PDL, or PDL combined with TAC injection according to the Vancouver scar scale (VSS) score before each treatment. Before the first treatment (hereinafter referred to as before treatment) and 12 months after the first treatment (hereinafter referred to as after treatment), the keloids were assessed by VSS, patient and observer scar assessment scale (POSAS), and the effect of keloids on the quality of life of patients was evaluated with dermatology life quality index (DLQI) scale. Twelve months after treatment, the curative effect of keloid was evaluated according to the VSS score and the effective rate was calculated. The first effective time and the cumulative times of TAC injection at the first effective time, the number of follow-up and the occurrence of adverse reactions of keloids within 12 months after treatment were recorded, and the incidence of adverse reactions was calculated. Data were statistically analyzed with paired sample t test, independent sample t test, Wilcoxon rank-sum test, Mann-Whitney U test, chi-square test, and Fisher's exact probability test. Results: The total VSS scores of patients' keloids in TAC group and dynamic treatment group 12 months after treatment were significantly lower than those before treatment (with t values of 7.53 and 8.09, respectively, P<0.01), and the total scores of pigmentation and vascularity in VSS and POSAS, the total POSAS score, and the DLQI scale score were significantly lower than those before treatment (with Z values of -3.71, -4.04, -4.21, -4.11, -3.76, -3.73, -3.92, and -3.93, respectively, P<0.01). The total scores of pigmentation and vascularity in VSS and POSAS of patients' keloids in dynamic treatment group 12 months after treatment were significantly lower than those in TAC group (with Z values of -2.03 and -2.12, respectively, P<0.05). Twelve months after treatment, the effective rate of patients' keloids in dynamic treatment group was significantly higher than that in TAC group (χ2=3.88, P<0.05). The first effective time of patients' keloids in dynamic treatment group was 5.5 (2.0, 6.0) months, which was significantly shorter than 6.0 (2.3, 10.3) months in TAC group (χ2=4.02, P<0.05). The cumulative times of TAC injection at the first effective time of patients' keloids in dynamic treatment group was 3.2±1.7, which was significantly less than 4.2±1.8 in TAC group (t=2.09, P<0.05). The number of follow-up of patients' keloids within 12 months after treatment in dynamic treatment group was significantly more than that in TAC group (t=-2.94, P<0.01), and the total incidence of adverse reactions was lower than that in TAC group but without statistically significant difference (P>0.05). Conclusions: Compared with TAC injection alone, PDL dynamically combined with TAC in the treatment of keloid can shorten the effective time, reduce the number of TAC injection, and improve the patient's compliance and clinical efficacy.

Abstract
Objective: To investigate the effect of pelvic packing on the control of intractable postpartum hemorrhage after emergency perinatal hysterectomy (EPH). Methods: Eleven cases with complete clinical data of pelvic packing due to failure of hemostasis after EPH were collected to evaluate the outcome, complications, hospital stay of pregnant women, and to analyze the factors affecting the effect of pelvic packing. The cases included patients who were admitted to the Third Affiliated Hospital of Guangzhou Medical University after pelvic packing treatment in the other hospital due to continuous bleeding after EPH or who were referred to our hospital for pelvic packing treatment due to continuous bleeding after EPH from January 2014 to August 2021. Results: The median gestational week of 11 pregnant women was 38.3 weeks(38.0-39.9 weeks) , and the methods of termination of pregnancy were cesarean section in 7 cases (7/11) and vaginal delivery in 4 cases (4/11). The median time between postpartum hemorrhage and pelvic tamponade was 10 hours (5-57 hours), the median amount of bleeding was 8 500 ml(4 800-15 600 ml) , the median number of pelvic tamponade was 3 pieces (2-7 pieces), and the median retention time of gauze pad was 6.0 days (3.0-6.0 days). The median frequency of laparotomy in this pregnancy was 3 times (2-3 times), with a maximum of 4 among the 11 cases, the first pelvic packing was successful in hemostasis in 9 cases, and the final successful treatment in all of the 11 cases. All parturients had hemorrhagic shock (11/11) and disseminated intravascular coagulation (11/11) before pelvic packing. Other common complications were multiple organ dysfunction syndrome (9/11), cardiac arrest (4/11), deep vein thrombosis (3/11), septic shock (3/11), and intestinal obstruction (1/11). All parturients took out the gauze after the coagulation function returned to normal and there was no active bleeding. The recovery time of coagulation function in 11 cases was 3 days (3-5 days), the retention time of gauze pad was 6 days (3-6 days), the median length of stay in intensive care unit was 14 days (11-26 days), and the median total length of stay was 22 days (16-49 days). Conclusions: Pelvic packing could be used as a temporary strategy for intractable postpartum hemorrhage after EPH, which provides a key time for injury control resuscitation for patients with unstable vital signs. This technology provides an opportunity for referral to superior medical institutions and further treatment.

Abstract
This study aimed to investigate the effects of chitooligosaccharide (COS) on intestinal barrier, antioxidant capacity, and immunity of lipopolysaccharide (LPS)-challenged laying hens. A total of 360 Hy-line Brown laying hens (80-wk-old) were randomly divided into 5 groups with 6 replicates of 12 birds. Hens were fed a corn-soybean meal basal diet supplemented with different COS levels (0; 5; 10; 15; 20 mg/kg) for 8 wk. The results showed that 15 mg/kg COS administration elevated albumen height and Haugh unit (P < 0.05), and numerically optimized productive performance (P > 0.05), therefore, the dosage of 15 mg/kg was chosen for the subsequent experiment. Thereafter, 12 birds from non-supplemented group were randomly selected and assigned into 2 groups, and birds in each group were administered (1.5 mg/kg BW, i.p.) with saline (control group) or LPS (challenge group). Another 6 hens from 15 mg/kg COS-supplemented group were selected and injected with LPS in the same way. Compared with the control group, LPS-challenged birds exhibited elevated circulating diamine oxidase activity, and reduced jejunal villus height and ratio of villus height to crypt depth, and these indices were reversed to control levels by COS (P < 0.05). Also, LPS increased malondialdehyde accumulation and reduced several antioxidant enzyme activities in the intestinal mucosa (P < 0.05). Additionally, LPS increased jejunal secretory IgA and interferon-γ (IFN-γ), and ileal secretory IgA, IgM, and interleukin-1β (IL-1β) concentrations, whereas COS reduced jejunal IFN-γ and IL-1β, and ileal IgM levels (P < 0.05). Moreover, LPS down-regulated mRNA abundance of jejunal occludin and claudin 2, and upregulated expression of jejunal nuclear factor erythroid-2 related factor 2, superoxide dismutase 1, and IFN-γ as well as ileal IL-1β (P < 0.05). Besides, COS increased jejunal occludin and ileal claudin 2, nuclear factor erythroid-2 related factor 2, and heme oxygenase-1 expression, and decreased jejunal IFN-γ and IL-1β abundance (P < 0.05). These results suggested that COS could alleviate LPS-induced intestinal barrier impairment, and oxidative and immunological stress in laying hens.

Abstract
Objective: To examine the safety and feasibility of uniportal video-assisted thoracoscopic (VATS) decortication in patients presenting with stage Ⅲ tuberculous empyema. Methods: From August 2017 to July 2020, 158 patients of stage Ⅲ tuberculous empyema underwent uniportal VATS decortication with partial rib resection and customized periosteal stripper in Department of Thoracic Surgery, Shanghai Pulmonary Hospital. There were 127 males and 31 females, aged (M(IQR)) 32(28) years (range:14 to 78 years). Follow-up was performed in the outpatient clinic or via social communication applications, at monthly thereafter. If there was no air leak and chest tube drainage was less than 50 ml/day, a chest CT was performed. If the lung was fully re-expanded, chest tubes were removed. All patients received a follow-up chest CT 3 to 6 months following their initial operations which was compared to their preoperative imaging. Results: There was one conversion to open thoracotomy. The operative time was 2.75 (2.50) hours (range: 1.5 to 7.0 hours), and median blood loss was 100 (500) ml (range: 50 to 2 000 ml). There were no perioperative mortalities. There were no major complications except 1 case of redo-VATS for hemostasis due to excessive drainage and 1 case of incision infection, The incidence of prolonged air leaks (>5 days) was 80.3%(126/157). The postoperative hospital stay was 5.00 (2.25) days (range:2 to 15 days). All patients were discharged with 2 chest tubes, and the median duration drainage was 21.00 (22.50) days (range: 3 to 77 days). Follow-up was completed in all patients over a duration of 20 (14) months (range: 12 to 44 months). At follow-up, 149 patients(94.9%) recovered to grade Ⅰ level, 7 patients to grade Ⅱ level, and 1 patient to grade Ⅲ level. Conclusion: Uniportal VATS decortication involving partial rib resection and a customized periosteal stripper is safe and effective for patients with stage Ⅲ tuberculous empyema.

Abstract
1. This study investigated the effects of dietary betaine supplementation on growth performance, meat quality, muscle fatty acid composition and antioxidant ability in slow-growing broiler chickens.2. In total, 400, one-day-old female Xueshan broiler chicks were randomly divided into five groups with eight replicates of ten chickens each for 102 d. Broilers were fed a basal diet supplemented with 0, 125, 250, 500 or 1,000 mg/kg betaine.3. Broilers fed betaine had better feed conversion efficiency and weight gain (P < 0.05) and increased meat redness and yellowness 24 h after slaughter. Supplementation linearly decreased cooking loss and drip loss from breast muscle (P < 0.05). Muscular resilience was improved and tenderness increased (P < 0.05). Intra-muscular saturated fatty acids decreased, while total monounsaturated fatty acids and polyunsaturated fatty acids increased (P < 0.05). Betaine increased activities of glutathione peroxidase (GPx) and total superoxide dismutase (SOD), glutathione (GSH) level, ratio of reduced glutathione/oxidised glutathione, and activity of scavenging hydroxyl radicals. It increased the activity of total antioxidant capacity (T-AOC) in the breast muscle (P < 0.05). Moreover, supplementation up-regulated (P < 0.05) mRNA expression levels of blood and antioxidant markers.4. In conclusion, 1000 mg/kg betaine can be recommended as a supplement for slow-growing, Xueshan chicken.

Abstract
Thalidomide and its derivatives have been used in the treatment of myelodysplastic syndrome (MDS) because of their anti-angiogenic and immunomodulatory effects. In recent years, some studies have found that thalidomide and its derivatives not only showed significant efficacy in lower-risk MDS patients with del (5q), but also showed advantages in non-del (5q) MDS patients. In addition, the discovery of its molecular targets and new substrates makes it possible to develop a new generation of immunomodulatory drugs (IMiDs) and to design IMiDs-based proteolysis-targeting chimeras. In this review, the new progress in mechanism and clinical application of thalidomide and its derivatives were summarized briefly, so as to provide a more scientific, reasonable and effective scheme to the treatment of MDS.

Abstract
This study aimed to investigate the age-related changes of hepatic metabolism and antioxidant capacity of laying hens at 3 different ages. A total of 192 Hy-line Brown laying hens were assigned into 3 groups: 1) 195-day-old (D195 group); 2) 340-day-old (D340 group); 3) 525-day-old (D525 group). Each group replicated 8 times with 8 hens at the same age. Higher activity of aspartate aminotransferase and lower contents of total protein and globulin were observed in the serum of 525-day-old hens in comparison with their 195-day-old counterparts (P < 0.05). The 525-day-old hens accumulated higher contents of total cholesterol and triglyceride in the liver than 195-day-old birds. Additionally, compared with hens from D195 or D340 group, 525-day-old birds exhibited a lower circulating estradiol level (P < 0.05). For antioxidant capacity, birds in the D525 group showed a higher malondialdehyde concentration in both serum and liver as compared with D195 or D340 group (P < 0.05). The 525-day-old hens also exhibited lower glutathione peroxidase activities in both serum and liver when compared with 195-day-old birds (P < 0.05). Simultaneously, there was a decline of hepatic superoxide dismutase activity in the D525 group in comparison with D195 group (P < 0.05). Compared with 195-day-old counterparts, 340-day-old birds upregulated the mRNA abundance of nuclear factor erythroid-2 related factor 2 and glutathione peroxidase 1 in the liver (P < 0.05). In contrast, hens from D525 group showed the downregulation of hepatic nuclear factor erythroid-2 related factor 2, NAD(P)H quinone dehydrogenase 1, and superoxide dismutase 1 when compared with D340 group (P < 0.05). These results indicated that increasing age can adversely affect liver metabolism and function of laying hens.

Abstract
Scars caused by trauma will not only affect the appearance and cause dysfunction, but also affect the quality of psychological life of the patients to varying degrees. With the in-depth understanding of the process of scar formation after trauma and the continuous development of related intervention methods, early intervention within 3 months after trauma has been proved to be able to promote wound healing, inhibit scar hyperplasia, and interfere with the natural remodeling of scar collagen. This review summarizes the process of scar formation after trauma, as well as the timing and method of early intervention.

Abstract
Recent studies have shown that intervention in the early post-traumatic period can inhibit scar hyperplasia and promote scar maturation. Because of its definite therapeutic efficacy and few adverse reactions, it has become an important auxiliary method to prevent scar formation after trauma. This article reviews the research advances on the mechanism of pulsed dye laser in inhibiting the formation of early hypertrophic scar after trauma, the timing of intervention, and its complications and treatment methods, in order to provide a basis for the early prevention and treatment of clinical post-traumatic scars.

Abstract
Traumatic scar can not only exert influence on appearance and function of patients, but also affect psychological health status and life quality of patients to varying degrees. At present, scholars have confirmed from basic research that mechanical tension promotes the proliferation of inflammatory cells, fibroblasts, and other cells, as well as angiogenesis and epithelialization through a variety of mechanical conduction pathways and plays an important role in the formation of hypertrophic scar. Clinical studies have confirmed that surgical methods and adjuvant treatment to reduce the mechanical tension on wound can promote wound healing and inhibit hyperplasia of scar. This article summarizes the mechanism of hypertrophic scar formation, and surgical methods and adjunct means of reducing mechanical tension in traumatic wounds, aiming to provide a reference for reducing formation of hypertrophic scar in clinics.

Abstract
Infectious diseases are still one of the leading causes of morbidity and death globally, affecting public health and life, social and economic development, and even national security. Early detection focuses on detecting the abnormal information of infectious disease outbreaks or epidemics in a timely and sensitive way to conduct field investigation and verification. It is also a precursor to effective surveillance and early warning system. The effective surveillance and early warning system can fully and accurately understand the real conditions, driving forces, and transmission chain of the occurrence of a specific infectious disease outbreak and epidemic and put forward scientific and effective prevention and control strategies and measures. Due to the measurement of the resources support and the particular data collection value, it is not easy to obtain epidemiological, etiological, and other data information in a timely, complete and accurate manner. This paper summarized the theory and technology on early detection, effective surveillance, and early warning information on infectious diseases. It also integrated and utilized the multi-source data, including effective infectious disease surveillance and the country's early warning system, to better understand the outbreak epidemic, causes, risks, processes, and driving forces. Thus, it is possible to set up a sensitive, specific staging measurement innovative technical system to monitor, early warning, and timely respond to acute infectious diseases through multidisciplinary cooperation in China. It provides the basis for strengthening the surveillance and early warning of new emerging and major infectious diseases and public health emergencies, avoiding the spread of inadequate response to infectious disease, and preventing the resources waste of over-response.

Abstract
Objective: To investigate the impact of surgical treatment on quality of life in patients with locally recurrent rectal cancer (LRRC). Methods: A descriptive case series study was performed. The complete clinical data of 62 patients who met the diagnostic criteria of LRRC and treated by surgical procedures in Huashan Hospital of Fudan University from January 2012 to November 2019 were analyzed retrospectively. All the patients were followed up at least 12 months. Assessments of urinary function, sexual function, mobility function of lower limb and quality of life were documented. Patients with distant metastasis and surgical history of the urinary system were excluded. According to the criteria of Memorial Sloan Kettering Cancer Center (MSKCC), recurrence were divided into central (n=27), anterior (n=20), posterior (n=7), and lateral (n=8) subtypes. Baseline characteristics, surgical procedures and short-term complications were analyzed. International prostate symptom score (IPSS) and grade of voiding dysfunction were used to evaluate the urinary function. Higher score of IPSS and higher grade of voiding dysfunction indicated worse voiding function. Sexual function for both genders was assessed preoperatively and postoperatively. International index of erectile function-5 (IIEF-5) was used for assessment of male patients and higher score indicated better function. Female sexual function index (FSFI) was used in females and higher score indicated better function. Short-form health survey with 36 items (SF-36), yielding an 8-scale profile of functional health (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, emotional health and mental health) was used to evaluate the quality of life. The higher score indicated the better quality of life. Results: All the operations of 62 patients completed successfully and R0 resection rate was 88.7% (55/62). Postoperative surgical complications occurred in 16 cases (25.8%), including 3 patients of Clavien-Dindo classification III. At postoperative 3-month, 42 patients without ileum cystectomy or ureterostomy suffered from different grade of voiding dysfunction. IPSS increased significantly after the surgery (before surgery: 12.36±4.75, after surgery: 18.40±4.77, t=-9.128, P<0.001). There was no significant difference among the subtypes (P>0.05). At postoperative 12-month, IIEF-5 decreased from 14 (0~25) to 9 (0~19) in males (Z=-5.174, P<0.001) and FSFI deceased from 8.4 (2.0-27.0) to 2.0 (2.0-18.4) in females (Z=-3.522, P<0.001). Scores of physical functioning and role-physical decreased significantly [physical functioning: before surgery 70 (35-85), after surgery 65 (30-80), Z=-3.685, P<0.001; role-physical: before surgery 50 (0-50), after surgery 25(0-75), Z=-4.065, P<0.001], while those of social functioning role-emotional and mental health increased significantly after the surgery [social functioning: before surgery 44 (22-78), after surgery 56 (0-89), Z=-3.509, P<0.001; role-emotional: before surgery 17 (0-100), after surgery 33 (0-100), Z=-2.439, P=0.015; mental health: before surgery 40 (36-76), after surgery 52 (24-80), Z=-3.395, P<0.001]. All surgical procedures decreased the voiding function of LRRC patients and the sexual function of male patients (all P<0.01). However, only total pelvic exenteration and posterior pelvic exenteration decreased FSFI in female patients [before surgery: 8.4 (2.0-27.0) after surgery: 2.0 (2.0-18.4), Z=-2.810, P=0.005]. Conclusions: Multi-visceral resection in LRRC patients may damage voiding and sexual function. However, successful and effective surgical treatment can improve the psychosocial health of LRRC patients.

Abstract
Intestinal integrity, digestive enzyme activity, nutrient utilization, and egg quality of laying hens at different ages were evaluated and compared in this study. A total of 192 Hy-line Brown laying hens at 195-d-old (D195 group), 340-d-old (D340 group), and 525-d-old (D525 group) were allocated into one of 3 groups in accordance with their ages. Each group had 8 replicates of 8 birds each, and all birds were fed a maize-soybean meal basal diet for a 2-wk experiment. Compared with the D195 group, intestinal villus height and ratio of villus height to crypt depth, as well as serum D-lactate content increased in the D525 group (P < 0.05). The sucrase and maltase activities in the jejunal mucosa, amylase activity in the pancreas, and trypsin activity in the jejunal chyme of 525-d-old hens were lower than their 195-d-old counterparts (P < 0.05). In addition, there was a decline of trypsin and lipase activities in the ileal chyme of hens from D525 group in comparison with D195 or D340 group (P < 0.05). Apparent retention of dry matter and crude protein of birds in D340 and D525 group decreased when compared with the D195 group (P < 0.05). Moreover, birds in the D525 group exhibited a lower level of ether extract retention, and higher contents of several excreted amino acids than those in the D195 group (P < 0.05). Compared with the D195 group, eggs harvested from D525 group exhibited lower albumen height, eggshell strength and thickness, and a higher egg weight (P < 0.05). In conclusion, increased intestinal permeability (higher serum D-lactate content), compromised digestive function (lower digestive enzyme activities and apparent nutrient retention, and higher concentrations of excreted amino acids), and poor egg quality (lower albumen height, eggshell strength, and thickness) were observed with increasing age in the laying hens.

Abstract
The aim of this study was to explore the protective effects of squalene supplementation on growth performance, oxidative status, and liver function of diquat-challenged broilers. One hundred forty-four 1-day-old male Ross 308 broiler chicks were allocated to 3 groups, and each group consisted of 6 replicates of 8 birds each. The three groups were as follows: 1) nonchallenged broilers fed with a basal diet (control group), 2) diquat-challenged broilers fed a basal diet, and 3) diquat-challenged broilers fed with a basal diet supplemented with 1.0 g/kg of squalene. Broilers were intraperitoneally injected with 20 mg/mL of diquat solution at a dosage of 1 mL/kg of BW or an equivalent amount of saline at 20 d. Compared with the control group, weight gain and BW change rate during 24 h after injection were decreased by diquat challenge (P < 0.05), and the diquat-induced compromised growth performance was improved by squalene supplementation (P < 0.05). Diquat administration reduced plasma superoxide dismutase activity and increased malondialdehyde accumulation and glutathione peroxidase activity in both plasma and the liver (P < 0.05). In contrast, plasma glutathione peroxidase activity in diquat-challenged broilers was reduced by squalene supplementation (P < 0.05). The hepatic glutathione level was reduced by diquat administration (P < 0.05), whereas its level in plasma and the liver of diquat-challenged broilers was increased by squalene supplementation (P < 0.05). The relative liver weight of broilers was increased by diquat challenge (P < 0.05), with its value being intermediate in the squalene-supplemented group (P > 0.05). The plasma aminotransferase activities and total bilirubin concentration were increased by diquat challenge (P < 0.05), which were reduced by squalene supplementation (P < 0.05). The mRNA abundance of hepatic nuclear factor erythroid 2–related factor 2 (P < 0.05) was upregulated by diquat treatment, regardless of squalene supplementation. The mRNA abundance of hepatic glutathione peroxidase 1 and B-cell lymphoma/leukemia 2–associated X protein was upregulated by diquat challenge (P < 0.05), which was reversed by squalene administration (P < 0.05). Squalene increased NAD(P)H quinone dehydrogenase 1 mRNA abundance and decreased caspase 3 mRNA abundance in the liver of diquat-challenged broilers (P < 0.05). The results suggested that squalene can increase weight gain, improve oxidative status, and alleviate liver injury in diquat-challenged broilers.

Abstract
OBJECTIVE To investigate the effects of matrine on antigen presentation of dendritic cells (DCs), and to explore the pharmacological mechanism of matrine on anti-tumor effect. METHODS Different concentrations (0, 1, 2, 4, 8 and 16 µ g/mL) of matrine were co-cultured with DCs, the harvested DCs were co-cultured with antigens of Lewis lung cancer (LLC) cells, and then DCs and T cells were co-cultured to produce DCs-activated killer (DAK) cells, which have significant tumor-killing activity. The expression of cytokines, mRNA and protein of toll-like receptors (TLRs) in DCs were detected by enzyme linked immunosobent assay, polymerase chain reaction and Western blot, respectively. And the killing effect of DAK were measured by MTT assay. RESULTS Matrine significantly increased the mRNA expression of TLR7, TLR8, myeloid differentiation factor 88 (MyD88), tumor necrosis factor receptor-associated factor 6 (TRAF-6) and I κ B kinase (IKK), as well as the protein expression of TLR7 and TLR8, and up-regulated the levels of interleukin-12 (IL-12), IL-6 and tumor necrosis factor-α (TNF-α), meanwhile, it also increased the expressions of MHC-II, CD54, CD80 and CD86 in DCs. DCs-activated effector T cells had significant tumor-killing activity. When the concentration of matrine was more than 4 µg/mL, all indices had significant difference (P<0.01 or P<0.05). CONCLUSION Matrine plays an anti-tumor role by regulating TLRs signal transduction pathway, promoting the secretion of inflammatory cytokines and enhancing immune function.

Abstract
In addition to restoring oral function, stable aesthetic outcome has become the goal of oral implant therapy. To ensure the harmonious appearance of the restoration and the natural tooth and to obtain the ideal hard and soft tissue structure, clinicians should have a clear understanding of the factors that influence the success of aesthetics and apply different technique accordingly. In view of the recent progress in the field of oral implant, the factors affecting the aesthetic outcome of implant treatment were discussed including neck design of implant, design of customized abutment, tissue regeneration and gingival papilla height, so as to provide clinical reference to improving the aesthetic outcome of oral implant treatment.

Abstract
This study investigated protective effects of mannan oligosaccharide (MOS) inclusion on growth performance, intestinal oxidative status, and barrier integrity of cyclic heat-stressed broilers. A total of 240 one-day-old chicks were allocated into 3 treatments of 10 replicates each. Control broilers reared at a thermoneutral temperature were fed a basal diet, whereas broilers in heat stress and MOS groups raised at a cyclic high temperature (32 to 33°C for 8 h/d) were given the basal diet supplemented with 0 or 250 mg/kg MOS, respectively. Compared with control group, heat stress decreased (P < 0.05) average daily gain and feed conversion ratio during grower, finisher, and entire periods, average daily feed intake during finisher and entire periods, and ileal superoxide dismutase activity at 42 D, whereas increased (P < 0.05) rectal temperature at 21 and 42 D and jejunal malondialdehyde content at 42 D. Dietary MOS increased (P < 0.05) average daily gain, average daily feed intake, and feed conversion ratio during finisher and entire periods, but decreased (P < 0.05) jejunal malondialdehyde concentration of heat-stressed broilers at 42 D. Heat stress decreased (P < 0.05) jejunal villus height (VH) and claudin-3 gene expression at 21 D, and VH and VH: crypt depth (CD) ratio in jejunum and ileum as well as mRNA abundances of jejunal mucin 2 and occludin, and ileal mucin 2, zonula occludens-1, and occludin, and claudin-3 at 42 D, whereas increased (P < 0.05) serum D-lactate acid content at 21 and 42 D, and serum diamine oxidase activity and jejunal CD at 42 D. The MOS supplementation increased (P < 0.05) jejunal VH at 21 D, VH and VH: CD of jejunum and ileum at 42 D, mRNA abundances of jejunal occludin and ileal mucin 2, zonula occludens-1, and occludin at 42 D, whereas reduced (P < 0.05) ileal CD at 42 D. These results suggested that MOS improved growth performance, and oxidative status and barrier integrity in the intestine of broilers under cyclic heat stress.

Objective: To identify the risk factors of perioperative complications after radical gastrectomy for gastric cancer. Methods: A retrospective case-control study was performed. Case inclusion criteria: (1) patients undergoing radical gastrectomy (D2); (2) primary gastric cancer without distant organ metastasis confirmed by postoperative pathology; (3) no neoadjuvant chemotherapy before surgery. Patients with peritoneal tumor dissemination found during operation, undergoing palliative operation due to distant metastasis, and undergoing combined organ resection and those without complete clinicopathological data were excluded. According to the above criteria, 426 patients with gastric cancer at our department from January 2015 to June 2017 were included in this study. Of 426 patients, 285 were male and 141 were female with a mean age of (55.4±9.7) years. According to the "Japan Clinical Cancer Research Group (JCOG) classification criteria for postoperative complications of gastric cancer", patients with grade II and higher complications were classified as complication group, and patients with no complication or grade I complication were classified as non-complication group. Baseline data were compared between two groups. Associations of perioperative complication with gender, age, body mass index, preoperative routine laboratory test, American Society of Anesthesiologists (ASA) classification, activities of daily living (ADL) assessment, past medical history as well as preoperative conditions (hypertension and/or diabetes), surgical resection procedure, incision type, operation time, intraoperative blood loss/body mass ratio were examined. Univariate analysis was performed using χ(2) test and the Wilcoxon rank sum test to screen the statistically significant variables associated with perioperative complications. The significant variables were included in multivariate logistic regression analysis to identify risk factors of perioperative complication. Results: Grade II or higher complications after surgery were developed in 97 patients (22.8%), which included anastomotic leakage in 18 cases (4.2%), postoperative bleeding in 9 cases (2.1%), abdominal abscess in 5 cases (1.2%), intestinal obstruction in 5 cases (1.2%), pancreatic leakage in 1 case (0.2%), and other adverse events in 59 cases (13.8%). Univariate analysis suggested that the gender, age, ADL, incision type, intraoperative blood loss/body mass ratio, and operation time were associated with perioperative complication (all P<0.05). Multivariate analysis revealed that elder age (OR=1.033, 95% CI:1.013-1.053, P=0.013), incision type of laparotomy (OR=2.091, 95% CI:1.247-3.508, P=0.004), longer operation time (OR=1.004, 95% CI:1.001-1.007, P=0.001) and higher ratio of intraoperative blood loss/body mass (OR=1.100, 95% CI: 1.039-1.163, P=0.031) were risk factors for postoperative complications. Conclusion: Attention should be paid to those cases with elder age, laparotomy incision, longer operation time and higher ratio of intraoperative blood loss/body mass, and perioperative management after gastrectomy should be improved.

Abstract
Graphene derivatives are the new bioactive material with good physical and chemical properties and excellent biocompatibility. It has been found that graphene derivatives can improve the mechanical properties of biomaterials and promote the adhesion, proliferation and differentiation of osteoblast-related cells, so as to promote implant-bone bonding and repair of bone defects. This makes it a research hotpot in the field of bone tissue regeneration. In this paper, the mechanism of graphene derivatives promoting bone regeneration and their application in the oral field were reviewed, so as to provide theoretical basis for their application in basic and clinical research.

Abstract
Objective: To investigate the ratio of transfer cesarean section after trial of labor and maternal-fetal outcomes based on Robson classifications. Methods: The delivery data by cesarean section in Third Affiliated Hospital of Guangzhou Medical University from January 1st, 2009 to December 31st, 2015 (gestational age ≥28 weeks and newborn birth weight >1 000 g) were retrospectively collected. The ratio of transfer cesarean section after trial of labor and maternal-fetal adverse outcomes were analyzed by weighted adverse outcome score in different Robson classifications. Results: (1) The highest ratio of transfer cesarean section after trial of labor was classification 9 (all abnormal lies, including previous cesarean section and breech were excluded) reached 47.31% (431/911) , followed by classification 2 (nulliparous women with a single cephalic pregnancy, ≥37 weeks gestation who had labour induced) accounted for 44.90%(409/911). (2)The tops of weighted adverse outcome score of transfer cesarean section after trial of labor were classification 10 (single cephalic pregnancy at <37 weeks gestation, including women with previous cesarean delivery) 24.55, classification 5 (single cephalic pregnancy multiparous women, with at least one previous cesarean delivery, ≥37weeks gestation) 3.64. Conclusion: Carefully evaluating the delivery mode and emphasizing the intrapartum management in nulliparous women with a single cephalic pregnancy, at ≥37 weeks gestation who had labour induced and trial of labor after cesarean section is essential to reduce the risk of adverse outcomes in transfer cesarean section after trial of labor.

Abstract
This experiment was conducted to evaluate the effects of bile acids (BAs) on the growth performance and lipid metabolism of broilers fed with different energy level diets. 480 one-day-old Arbor Acres broilers (45.01 ± 0.26 g) were allotted to a 2 × 2 factorial design with 2 levels of energy (basal or high-energy level) and 2 levels of BAs (with or without BAs supplementation), resulting in 4 groups of 8 replicates; the experiment lasted 42 d. High-energy diets decreased the feed/gain ratio (F/G) from 1 to 21 d (P < 0.05), and increased the liver index and abdominal fat percentage at 42 d (P < 0.05). The serum total triglyceride (TG) and high-density lipoprotein cholesterol at 42 d were increased by high-energy diets (P < 0.05), while the hepatic lipoprotein lipase (LPL) activity at 21 and 42 d was decreased (P < 0.05). BAs supplementation increased the body weight at 21 d and decreased the F/G during entire period (P < 0.05), as well as improved the carcass quality reflected by decreased abdominal fat percentage at 42 d and increased breast muscle percentage at 21 and 42 d (P < 0.05). The serum TG at 21 and 42 d were decreased by BAs (P < 0.05), and the hepatic LPL activity at 42 d was increased (P < 0.05). In addition, high-energy diets increased the expression of sterol regulatory element binding transcription factor 1, acetyl-CoA carboxylase, and fatty acid synthase (P < 0.05), while BAs diets decreased these genes expression (P < 0.05). Moreover, BAs supplementation also increased the expression of carnitine palmitoyltransferase 1 (P < 0.05), which was increased in high-energy groups (P < 0.05). In conclusion, BAs supplementation could increase growth performance, elevate carcass quality, and improve lipid metabolism in broilers.

Abstract
This study was conducted to investigate the effect of betaine on growth performance, carcass characteristics, myogenic gene expression, and insulin-like growth factor-1 (IGF-1) signaling pathway in partridge shank broiler chickens. A total of 192 one-day-old partridge shank broiler chickens were randomly divided into 4 groups with 6 replicates of 8 chickens for a 52-d feeding trial. Broilers were fed a basal diet supplemented with 0 (control), 250 (B250), 500 (B500), or 1,000 (B1000) mg/kg betaine. Compared with the control group, the B500 and B1000 groups had higher (P < 0.05) body weight gain (BWG), and the B500 group had a lower (P < 0.05) feed/gain ratio (F:G) during the whole trial period. Moreover, the B1000 group increased (P < 0.05) the breast muscle yield and decreased (P < 0.05) relative abdominal fat weight. The mRNA expression of myocyte enhancer factor 2B (MEF2B) and mechanistic target of rapamycin (mTOR) and mTOR phosporylation were higher (P < 0.05) in both breast and thigh muscles in the B500 and B1000 groups than those in the control group. The higher (P < 0.05) concentration and mRNA expression of IGF-1 were also observed in breast muscle in the B500 and B1000 groups. Additionally, the B1000 group up-regulated (P < 0.05) the mRNA level of myogenic differentiation factor 1 (MyoD1) in breast muscle and myogenin (MyoG) in thigh muscle. In conclusion, diets supplemented with 500 or 1,000 mg/kg betaine improved the growth performance of partridge shank broiler chickens during the whole trial period, and the B1000 group significantly improved the breast muscle growth. These improvements might result from increased mRNA expression of MyoD1 and MEF2B in breast muscle and MyoG and MEF2B in thigh muscle, and through alterations in IGF-1/mTOR signaling pathway.

Abstract
This study aimed to evaluate the impact of oxidative modification on soybean meal (SBM) proteins after exposure to different heating times, and the effects of the oxidized SBM on the growth performance [average daily feed intake (ADFI), average daily gain (ADG), and feed to gain ratio (F: G)], oxidative redox status [(reactive oxygen species (ROS), total antioxidant capacity (TAC), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA), and protein carbonyl (PC)]. A total of 400 one-day-old Arbor Acres chicks were randomly divided into 5 treatment groups with 8 replicates of 10 birds each. Birds in the control group (CON) were fed diet containing non-heated SBM, and those in the treatment groups were fed SBM heated at 100°C for 1, 2, 4, and 8 h, for 42 d. Heated SBM (HSBM) showed a relatively higher PC content in vitro. The ADG decreased, whereas the F:G increased linearly with an increase in heating time during the starter (days 1 to 21), grower (days 22 to 42), and the overall growth phases (days 1 to 42; P < 0.05). However, the ADFI decreased linearly only during the grower phase (P < 0.05). The plasma, liver, and jejunum ROS levels, MDA concentrations, and PC contents increased linearly (P < 0.05) in broilers fed HSBM. Furthermore, the TAC in the plasma and jejunum, and the total SOD and GSH-Px activities in the plasma, liver, and jejunum decreased linearly (P < 0.05) in broilers when feeding HSBM. (P < 0.05). The mRNA level of Nrf2 in the liver and jejunum was lower (P < 0.05) in broilers fed diet containing the SBM after 8 h heat-treatment than in those fed the CON diet at days 42. This study suggested that heat-induced protein oxidation of SBM could decrease growth performance and impair antioxidant status of broilers.

Abstract
This study was conducted to investigate effects of modified palygorskite (MPal) supplementation on the laying performance, egg quality and mineral element content, immunity, oxidative status, and intestinal integrity and barrier function of laying hens. A total of 360 52-week-old Hyline Brown hens were randomly assigned into four dietary treatments for a 7-week feeding trial. The birds were fed a basal diet supplemented with 0 (control group), 0.25, 0.5, and 1 g/kg MPal, respectively. The supplementation of MPal did not alter laying performance and egg quality among groups. Compared with the control group, MPal inclusion decreased lead (Pb) content in yolks at 49 days, and either 0.5- or 1-g/kg MPal supplementation decreased Pb accumulation in yolks at 25 days and manganese (Mn) accumulation in yolks at 25 and 49 days. The contents of jejunal secretory immunoglobulin A (SIgA), ileal SIgA, and immunoglobulin G were decreased by the dietary 0.5-g/kg MPal supplementation. The supplementation of MPal also decreased malondialdehyde content in jejunum and ileum, and decreased serum diamine oxidase activity of the laying hens at 25 and 49 days. The inclusion of 0.5 and 1 g/kg MPal enhanced villus height in jejunum and ileum, and also increased the ratio of villus height to crypt depth in ileum. In conclusion, MPal supplementation decreased Pb and Mn contents in yolks, and exhibited beneficial effects on the intestinal immunity, oxidative status, and intestinal integrity and barrier function of laying hens and its optimal dosage was 0.5 g/kg.

Abstract
FimA has been characterized as an important virulence factor for Porphyromonas gingivalis (Pg). These structures play a major role in the mechanisms of adhesion and invasion of Pg to host cells, and can induce cellular activation and cytokines release. FimA can also promote biofilm formation and induce immuno-inflammatory response of host cells. Many studies have characterized FimA to be associated with periodontitis and cardiovascular disease. Pg strains are classified into six types based on divergent nucleotide sequences of the fimA gene (types Ⅰ、Ⅰb、Ⅱ、Ⅲ、Ⅳ andⅤ). The expression of fimbriae is regulated by the fimA gene, which may be the key factor that leads to virulence diversities of Pg, At present, the research on the pathogenesis of FimA mainly focuses on periodontitis and atherosclerosis, which is of great significance for the prevention and treatment of diseases. This paper reviewed the pathogenic effect of FimA in the development of above mentioned two diseases and its application in the prevention.

Abstract
This experiment was conducted to investigate the effects of dietary methionine (Met) on growth performance, carcass traits, meat quality and oxidative status of breast muscle in fast- (Arbor Acres, AA) and slow- (Partridge Shank, PS) growing broilers from 1 to 42 d of age. The broilers were divided into a 2 × 3 factorial design with 6 replicates per treatment. Diets were formulated to contain low (LM, 0.35 and 0.31% during 1 to 21 and 22 to 42 d), adequate (AM, 0.50 and 0.44%) and high (HM, 0.65 and 0.57%) Met, respectively. The main effects showed that the AA broilers had superior (P < 0.05) growth performance and carcass traits compared with those of the PS broilers. The breast muscle of the AA broilers had lower (P < 0.05) drip loss and malondialdehyde (MDA) content but higher (P < 0.05) cooking loss and glutathione peroxidase (GPX) activity than that of the PS broilers. Compared with the LM diets, the AM and HM diets increased (P < 0.05) 42-d BW, ADG, eviscerated yield and breast muscle yield only in the AA broilers. The AA broilers fed the HM diets had higher (P < 0.05) pH but lower (P < 0.05) L*, cooking loss and ether extract content in breast muscle than those fed the LM diets. Compared with the LM diets, the HM diets resulted in strain-dependent changes (P < 0.05) in muscle oxidative status, with total antioxidant capacity (T-AOC) increased in the AA broilers, GPX activity increased and MDA content decreased in the PS broilers, and superoxide dismutase (SOD) activity increased in both strains of broilers. No differences were observed between the AM and HM diets except for T-AOC in breast muscle. In conclusion, the LM treatment negatively affected broiler growth performance, carcass traits, meat quality and oxidative status of breast muscle in a strain-dependent manner, particularly in the AA broilers, whereas the HM treatment had limited effects compared to the AM treatment.

Abstract
BACKGROUND Bacterial diarrhea is one of the most common causes for medical consultations, mortality and morbidity in the world. Diarrheagenic Escherichia coli (DEC) and non-typhoidal Salmonella (NTS) are major intestinal pathogens in developing countries, and the indiscriminate use of antibiotics has greatly contributed to resistant strains. Hence, the aim of the present study is to identify the antimicrobial resistance patterns and the molecular characteristics of DEC and NTS in southwest, China. METHODS 1121 diarrheal patients and 319 non-diarrheal subjects across all age groups were recruited from four sentinel hospitals from June 2014 to July 2015 in Kunming City, Yunnan Province. Each stool specimen was collected to detect DEC and NTS with standard microbiological and molecular methods. Antimicrobial resistance testing was performed with the Kirby-Bauer disk diffusion method, and the standards for antimicrobial susceptibility testing complied with the Clinical and Laboratory Standards Institute (CLSI). Molecular characterization of strains was carried out using pulsed-field gel electrophoresis (PFGE). A structured questionnaire was used to record basic epidemiological data (e.g. sex, age, residence, season, etc.). Data were analyzed using Chi-square or Fisher's exact test. RESULTS DEC was detected in 127 (11.33%) diarrhea cases and 9 (2.82%) non-diarrheal cases (χ2 = 20.69, P < 0.001, OR = 4.36, 95% CI: 2.19-8.65), and the prevalence of NTS isolated from diarrhea cases was higher than that of non-diarrheal cases across all age groups (n = 42, 3.75%, n = 1, 0.31%, χ2 = 10.10, P = 0.002, OR = 12.38, 95% CI: 1.70-90.29). The rates of resistance to ten antibiotics of DEC and NTS showed significant differences (χ 2 = 386.77, P < 0.001; χ2 = 191.16, P < 0.001). The rates of resistance to Amoxicillin and Clavulafiate (AMC), Cephalothin (CEP), Gentamicin (GEN) and Sulfamethoxazole-Trimethoprim (SXT) of DEC isolated from diarrhea cases were higher than those of NTS isolated from diarrhea patients (37.01% vs 14.29%, χ2 = 7.57, P = 0.006; 29.92% vs 11.90%, χ2 = 5.40, P = 0.02; 37.01% vs 11.90%, χ2 = 5.80, P = 0.016; 62.20% vs 26.19%, χ2 = 16.44, P < 0.001; respectively). Ciprofloxacin (CIP) was the most sensitive antibiotic for DEC and NTS strains isolated from diarrhea cases. Resistance rates of DEC isolates from cases and controls to more than three kinds antimicrobials (multidrug resistance, MDR) showed no significant differences (81.10% vs 88.89%, P = 0.33). Pulsotype patterns of DEC strains were highly diverse; however, the pulsotype pattern of NTS strains was closely related to the serotype. The pattern of S. enteritidis was highly similar, but the S. enterica Typhimurium strain was discrete. CONCLUSIONS Antibiotic resistance of Enterobacteriaceae is of great concern. The societal effects of antibiotic use justify strict monitoring to combat increases in antimicrobial resistance. Molecular epidemiology and systematic epidemiological investigation can provide accurate evidence for tracking the infection source.

Abstract
Retinal degeneration (RD) is a common eye disease which may result in blindness. At present, there is no effective clinical treatment for RD. It is known that apoptosis causes the occurrence and development of retinal degeneration, therefore antiapoptotic/antioxidative treatment has always been the focus in the treatment of RD. There are many kinds of antioxidant drugs, among which natural antioxidants are featured with reliable sources, high safety and less side effects. Hence researchers across the world made tremendous efforts in finding the safe and effective natural antioxidants. This paper focuses on the research progress of natural antioxidants in the treatment of retinal degeneration, in an effort to provide some valuable reference for clinical research.

Abstract
Keratinized mucosa in oral cavity plays an important role in periodontal health. The defect of keratinized mucosa may increase the risks of complication of oral implant surgery and restoration. Graft of keratinized tissue and connective tissue are still the gold standard for treating keratinized mucosa defect now. The current research focus on how to modulate non-keratinized mucosa to highly-efficient and minimally-invasive keratinized mucosa. Keratinocytes are critical components of oral mucosa and its final differentiation into keratinized mucosa is controlled by the connective tissue microenvironment involving a variety of molecules and ions. To fully understand keratinized differentiation of keratinocyte, this review focuses on its influence factors and possible mechanisms under the differentiation.

Abstract
The objective of this study was to evaluate influence of dietary palygorskite (Pal) supplementation on growth performance, mineral accumulations in the tissues (livers, kidneys, and muscles), antioxidant capacities, and meat quality of broilers fed lead (Pb)-contaminated diet. One-hundred forty-four male broiler chicks were randomly divided into three treatment groups, receiving a corn-soybean meal basal diet (the control group), the basal diet contaminated with 10 mg/kg Pb (the Pb group), and the basal diet with 10-g/kg Pal supplementation and 10-mg/kg Pb contamination (the Pal/Pb group) from 1 to 42 days of age, respectively. Treatments did not affect growth performance of broilers in the 42-day study (P > 0.05). Compared with the control group, Pb contamination increased Pb accumulation in the livers, kidneys, and muscles (P < 0.05); elevated malondialdehyde accumulation in the livers, kidneys, and breast muscles; glutathione peroxidase activity in the livers and superoxide dismutase activity in the kidneys (P < 0.05); exacerbated drip loss in the pectoralis muscles (P < 0.05); and reduced glutathione peroxidase activity in the pectoralis muscles (P < 0.05) of broilers at 42 days of age. The values of these parameters were reversed in the Pal/Pb group to levels comparable with those in the control group (P < 0.05). Additionally, Pal supplementation reduced redness value in the pectoralis muscles (P < 0.05), and decreased Cu concentration in the pectoralis muscles and livers at 42 days of age as well as its accumulation in the kidneys at both 21 and 42 days of age compared with the other two groups (P < 0.05). The results suggested that dietary Pal supplementation would decrease Pb residue in the tissues, alleviate oxidative stress, and affect meat quality of broilers exposed to Pb.

Abstract
1. The soybean meal (SBM) was heated at 100°C for 1, 2, 4 and 8 h, respectively, and their resultant oxidative status was evaluated. 2. A total of 400 one-day-old Arbor Acres broilers were randomly divided into 5 treatments with 8 replicates of 10 birds each, and fed with diets containing non-heated SBM (NHSBM) or 1 of 4 heated SBMs (HSBMs, SBMs heated at 100°C for 1, 2, 4 and 8 h, respectively) for 42 d. 3. The contents of carbonyl in the SBMs were both linearly and quadratically increased, whereas the nitrogen solubility index, and in vitro digestibility of crude protein (CP) and dry matter (DM) in the SBMs were both linearly and quadratically decreased as heating time increased (P < 0.05). The concentrations of sulfhydryl and total sulfhydryl in the SBMs were linearly decreased as heating time increased (P < 0.05). 4. The average daily gain was linearly decreased while the feed conversion ratio (FCR) was linearly increased in broilers as heating time of dietary HSBMs increased during both d 22-42 and d 1-42 of study (P < 0.05), though FCR of broilers during d 22-42 study were unaffected when the heating time of dietary HSBMs was 1 h (P > 0.05). The serum glucose concentration and the activity of trypsin at d 42, and the apparent total digestibility of CP and DM were all linearly reduced in broilers when heating time of dietary HSBMs increased (P < 0.05). However, 1 h HSBM has a numerical higher CP and DM digestibility than NHSBM. The serum urea nitrogen contents were both linearly and quadratically increased at both d 21 and 42 (P < 0.05), and relative pancreas weight was linearly increased at d 42 in broilers as heating time of dietary HSBMs increased (P < 0.05).

Abstract
Objective: To analyse the impaired lung functions of people with biofuel smoke exposure. Methods: Nonsmokers with biofuel smoke exposure were selected as research objects in a mountainous area of northern Guangdong where the families used biofuels as main energies and the nonsmokers without biofuel smoke exposure in the same area as control. Questionnaire interviews and spirometry tests were performed on all subjects. To analyse the differences of lung functions in both. Results: Seventy hundred and seventeen subjects were enro1led in this study.There were 530 nonsmokers with biofuel smoke exposure(observation group) including 442 women and 88 men, average age 54±10. There were 187 nonsmokers without biofuel smoke exposure(control group) including 141 women and 46 men, average age 54±10. There was no significant difference between two groups in age, height, weight, BMI, waist circumference, hip circumference and waist/hip ratio(P>0.05). The pulmonary ventilation function index(FEV(1)%Pred, FEV(1)/FVC) in the observation group was significantly less than that in control group [(100±18) vs.(106±25); (80±10) vs.(83±6) respectively, P<0.05]. Small airway function index(PEF25, PEF50, PEF75, MMPEF and MMPEF%Pred) was significantly less than that in control group(P<0.01). According to the univariate regression analysis and multivariate regression analysis, regression coefficients between BIOFUEL-INDEX and FEV/FVC was -0.1, 95%CI(-0.1, -0.1, P<0.01). According to the threshold analysis, the vertice of BIOFUEL-INDEX was 46.0, where the predicted Y value was 81.76, 95%CI (80.2, 83.33). When BIOFUEL-INDEX<46.0, the regression coefficient was 0, 95%CI (-0.1, 0.0)(P>0.05); when BIOFUEL-INDEX> 46.0, the regression coefficient 2 was -0.1, 95%CI (-0.2, -0.1)(P<0.01). The difference between coefficient 2 and 1 was -0.1, 95%CI (-0.2, 0.0), which was statistically significant (P<0.05). The Log-Likelihood ratio between Model I and Model Ⅱ had statistical significance (P=0.019). Conclusions: The biofuel smokes exposure causes damages in lung function.

Abstract
The present study was conducted to investigate different levels of palygorskite supplementation on the growth performance, meat quality, muscular oxidative status, and mineral element accumulation of broilers. One hundred ninety-two 1-day-old Arbor Acres broiler chicks were allocated to four dietary treatments with six replicates of eight chicks per replicate. Birds in the four treatments were given a basal diet supplemented with 0, 5, 10 and 20 g/kg palygorskite for 42 days, respectively. Compared with the control group, neither 5 g/kg nor 10 g/kg palygorskite inclusion affected growth performance of broilers during the 42-day study (P > 0.05). However, the highest level of palygorskite supplementation at 20 g/kg increased feed/gain ratio (F/G) of broilers (P < 0.001). Yellowness (P < 0.001) and redness (P = 0.003) of breast muscle and yellowness of leg muscle (P = 0.001) were decreased by palygorskite supplementation at the levels of 10 g/kg and especially 20 g/kg. In addition, redness of leg muscle was also reduced by the inclusion of 20 g/kg palygorskite (P = 0.009). In contrast, malonaldehyde (MDA) accumulation in the breast muscle was significantly increased by 20 g/kg palygorskite supplementation (P < 0.001). Supplementation of palygorskite at either 10 or 20 g/kg significantly decreased lead (Pb) accumulation in the breast (P = 0.001) or thigh (P = 0.045) and copper (Cu) accumulation in the breast (P = 0.022). In conclusion, growth performance, meat color, and antioxidant capacity of meat would reduce with the increasing level of palygorskite supplementation, whereas a higher level of palygorskite (10 or 20 g/kg) can alter mineral element accumulations in muscles as evidenced by reduced muscular Cu and Pb contents.

Abstract
The aim of this study was to investigate effects of L-threonine (L-Thr) supplementation on the growth performance, immunity, antioxidant status, and intestinal health of broilers at the early age. One hundred and forty-four 1-day-old male broiler chicks (Arbor Acres Plus) were allocated into 3 treatments with 6 replicates of 8 birds each, and fed a basal diet (analyzed Thr content, 7.87 g/kg) supplemented with 0 (control diet), 1 and 3 g/kg L-Thr for 21 d, respectively. Treatments did not alter growth performance of broilers. Compared with control, 1 g/kg Thr supplementation increased relative weight of spleen (P = 0.013). A higher level of Thr (3 g/kg) increased relative weight of thymus (P = 0.003). The supplementation of 3 g/kg Thr reduced Escherichia coli (P = 0.040) and Salmonella colonies (P = 0.015), whereas increased Lactobacillus colonies (P < 0.001) in the cecal contents. Thr supplementation increased intestinal villus height (P < 0.05), and the ratio of villus height to crypt depth (P < 0.001), and the values for these parameters were intermediate with 1 g/kg Thr. Goblet cell density was increased by Thr supplementation (P < 0.001). The jejunal immunoglobulin G content was increased by the inclusion of Thr (P = 0.002). Broilers fed diet supplemented with 1 g/kg Thr exhibited increased concentrations of jejunal immunoglobulin M (P = 0.037) and secretory immunoglobulin A (P = 0.018). Likewise, 3 g/kg Thr inclusion increased ileal secretory immunoglobulin A content (P = 0.023). The jejunal malondialdehyde accumulation was reduced by Thr inclusion (P = 0.012). A higher level of Thr inclusion also reduced malondialdehyde content in the serum (P = 0.029). The high level of Thr inclusion (3 g/kg) upregulated mucin-2 mRNA expression (P = 0.034), whereas downregulated the mRNA abundances of interferon-γ (P = 0.036) and interleukin-1β (P = 0.031) in the ileum. In conclusion, L-Thr supplementation can improve immunity, antioxidant capacity, and intestinal health of broilers at an early age.

Abstract
Background Acute diarrhea is a global health problem, resulting in high morbidity and mortality in children. It has been suggested that enteric pathogen co-infections play an important role in gastroenteritis, but most research efforts have only focused on a small range of species belonging to a few pathogen groups. This study aimed to assess the impact of co-infections with a broad range of enteric pathogens on children aged below five years who suffer from acute diarrhea in southwest China. Method A total of 1020 subjects (850 diarrhea cases and 170 healthy controls) were selected from four sentinel hospitals in Kunming, Yunnan province, southwest China, from June 2014 to July 2015. Stool specimens were collected to detect five virus (rotavirus group A, RVA; norovirus, NoV; Sapovirus, SaV; astrovirus, As; and adenovirus, Ad), seven bacterial (diarrheagenic Escherichia coli, DEC; non-typhoidal Salmonella, NTS; Shigella spp.; Vibrio cholera; Vibrio parahaemolyticus; Aeromonas spp.; and Plesiomonas spp.), and three protozoan (Cryptosporidium spp., Giardia lamblia, and Blastocystis hominis, B. hominis) species using standard microbiologic and molecular methods. Data were analyzed using the partial least square regression technique and chi-square test. Results At least one enteric pathogen was detected in 46.7 % (n = 397) of acute gastroenteritis cases and 13.5 % (n = 23) of healthy controls (χ2 = 64.4, P < 0.05). Single infection with RVA was associated with acute diarrhea (26.5 % vs. 5.8 %, P < 0.05). The prevalence of a single infection with B. hominis in diarrhea cases was higher than in healthy controls (3.1 % vs. 0.5 %, OR = 4.7, 95 % CI: 1.01–112.0). Single infection with NoV GII was not associated with diarrhea (4.4 % vs. 3.5 %, OR = 1.2, 95 % CI: 0.5–3.3). Single infections with bacterial species were not observed. The prevalence of co-infections with two enteric pathogens in diarrhea cases was higher than in asymptomatic children (20.1 % vs. 5.3 %, P < 0.05). RVA-NoV GII was the most common co-infection in symptomatic children (4.4 %), with it aggravating the severity of diarrhea. Conclusions Although it is clear that RVA has an overwhelming impact on diarrhea illnesses in children, co-infection with other enteric pathogens appears to also aggravate diarrhea severity. These findings should serve as evidence for public health services when planning and developing intervention programs.

Abstract
The Wnt signaling pathway plays a key role in insurgence and progression of many different forms of cancer. Some crucial components of the Wnt pathway have been proposed to be novel targets for cancer therapy. To date, the Wnt signaling pathway has not been studied in cutaneous squamous cell carcinoma (CSCC). This study was designed to investigate the expression of Wnt1 and SFRP1 from the Wnt pathway in CSCC. Tissue samples were obtained from 35 patients with CSCC and 30 controls admitted to the Xinjiang Uygur Autonomous Region People's Hospital at Urumchi City, China. Gene and protein expressions of Wnt1 and SFRP1 were quantified by immunohistochemistry and western blotting. Wnt1 expression was significantly higher (P < 0.05) in CSCC samples than in normal skin cells of the control subjects; in contrast, SFRP1 expression was significantly lower in CSCC tissues than that in tissues of control subjects (P < 0.05). Moreover, Wnt1 expression (P < 0.05) was found to be correlated with histopathological differentiation in CSCC, and negatively correlated with SFRP1 expression in CSCC (rs = -0.473, P = 0.015). Therefore, we concluded that Wnt1 and SFRP1 play important roles in the development of CSCC and could be potent markers for diagnosis, prevention, and therapy of CSCC.
