ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2020; 194:110404. [PMID: 32146197 DOI: 10.1016/j.ecoenv.2020.110404] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/07/2019] [Revised: 02/25/2020] [Accepted: 02/27/2020] [Indexed: 06/10/2023]
Abstract
Conversion of perfluoroalkyl acid (PFAA) precursors in the environment has been a hotspot research in recent years. This study firstly determined the spatial distribution of PFAAs and their precursors including 8:2 fluorotelomer unsaturated acid (8:2 FTUCA), perfluorooctane sulfoneamide (FOSA), and diperfluorooctane sulfonamido ethanol-based phosphate (di-SAmPAP), then investigated the conversion of the potential precursors in the seawater and sewage treatment plants (STPs) effluents. The results indicated that the target pollutants showed a typical concentration gradient from nearshore to offshore. And the obviously increased concentration of perfluorinated carboxylic acids (△[PFCAs]) after oxidation treatment can verify the existence of PFAA precursors in the seawater and STP effluents. The concentrations of PFCAs with carbon atom numbers 4-9 (PFCAC4-C9) revealed the most increase. Moreover, the levels of △[PFCAs] and the ratios of △[PFCAs] to their concentration before oxidation (△[PFCA]/[PFCA]before oxidation) indicated obvious spatial variations in the seawater and STP effluents. The higher levels of △[PFCAC4-C12] and the lower ratios of ∑△[PFCAC4-C12]/∑[PFAA]before oxidation were observed in the STP effluents, which implied that precursors might be decomposed during the sewage treatment process. These results suggested the STP effluents might have an important effect on the PFAAs levels of seawater.

Abstract
OBJECTIVE To quantitatively evaluate the diagnostic value of variable-temperature and isothermal nucleic acid amplification techniques in the detection of schistosomiasis japonica using a meta-analysis. METHODS The publications pertaining to the nucleic acid detection of schistosomiasis japonica were searched in electronic databases, including Chinese National Knowledge Infrastructure (CNKI), Wanfang Data, PubMed and ScienceDirect, and the compilations and proceedings of schistosomiasis were manually searched. In addition, the citations of publications associated with the nucleic acid detection of schistosomiasis japonica were traced using a document tracing method. The retrieved literatures were screened according to the inclusion and exclusion criteria, and data were extracted from the included literatures. The quality of the included literatures was assessed using the software RevMan version 5.3, and a meta-analysis was performed using the software MetaDiSc version 1.4. RESULTS A total of 19 publications covering 24 groups of studies were enrolled, including 5 Chinese publications and 14 English publications. There were 17 groups of studies reporting the comparison between the variable-temperature nucleic acid amplification technique and the golden standard, and 7 groups of studies showing the comparison between the isothermal nucleic acid amplification technique and the golden standard. Assessment of the literature quality indicated a minor overall bias of the included literatures, and the Deek funnel plot showed a possible publication bias in the documents reports variable-temperature nucleic acid amplification techniques. There was a heterogeneity caused by non-threshold effect among the studies associated with the variable-temperature amplification technique, and the random effects model was therefore used to combine the effects. The pooled sensitivity and specificity of the variable-temperature amplification technique were 0.81 (0.79 to 0.83) and 0.73 (0.71 to 0.74) for the diagnosis of schistosomiasis japonica, and area under the SROC curve was 0.944 3. There was no heterogeneity among the studies associated with the isothermal amplification technique, and the fixed effects model was therefore used to combine the effects. The pooled sensitivity and specificity of the isothermal amplification technique were 0.96 (0.94 to 0.98) and 0.95 (0.94 to 0.97) for the diagnosis of schistosomiasis japonica, and area under the SROC curve was 0.989 9. CONCLUSIONS Both variable-temperature and isothermal nucleic acid amplification techniques have a high efficiency for the diagnosis of schistosomiasis japonica, and the isothermal amplification technique shows a relatively higher accuracy than the variable-temperature amplification technique.

Abstract
This study evaluated the effects of different dietary zinc (Zn) levels on productive and reproductive performance, egg quality, tibial characteristics, plasma biochemical and antioxidant indices, and zinc deposition in laying duck breeders. A total of 504 Longyan duck breeders aged 21 wk were randomly allocated to 6 treatments and fed a basal diet (Zn, 27.7 mg/kg) or that basal diet supplemented with Zn (as ZnSO4·H2 O) at 10, 20, 40, 80, or 160 mg Zn per kg of feed for 20 wk. Each group had 6 replicates of 14 ducks each. Dietary Zn supplementation affected (P < 0.05) the egg production, FCR, and shell thickness of laying duck breeders from 21 to 40 wk, and there was a quadratic (P < 0.05) effect between them. Dietary Zn supplementation affected (P < 0.05) and quadratically (P < 0.001) increased the breaking strength, density, and dry defatted weight of tibias. Alkaline phosphatase, calcium, phosphorus, total superoxide dismutase, glutathione peroxidase (GSH-Px), and malondialdehyde (MDA) activities or content in plasma were affected (P < 0.05), and quadratically (P < 0.01) changed by dietary Zn levels. Dietary Zn supplementation affected (P < 0.01) and increased the Zn deposition in egg yolk (linear, P < 0.05; quadratic, P < 0.001) and tibia (linear, P < 0.05). The dietary Zn requirements, in mg/kg for a basal diet containing 27.7 mg/kg Zn, for Longyan duck breeders from 21 to 40 wk of age were estimated to be 65.4 for optimizing egg production, 68.6 for FCR, 102 for hatchling BW, 94.7 for eggshell thickness, 77.2 for tibial breaking strength, 81.4 for tibial density, 78.9 for tibial dry defatted weight, 69.5 for plasma GSH-Px activity, 72.4 for plasma MDA content, and 94.6 for Zn content in tibia. Overall, dietary Zn supplementation, up to 160 mg/kg feed, affected the productive performance, eggshell thickness, tibial characteristics, plasma antioxidant status, and Zn deposition of layer duck breeders. Supplementing this basal diet (27.7 mg/kg Zn) with 70 to 80 mg/kg additional Zn was adequate for laying duck breeders during the laying period.

Abstract
The construction of Yangtze River Economic Belt has been included in the national strategy of China, aiming to improve the economic level of the whole population, and to build a green ecological corridor with the joint development of economy, balance, ecology and equity. Yangtze River Economic Belt is the main area where schistosomiasis is endemic. During the economic construction, the prevention and control of schistosomiasis should be strictly carried out to facilitate the progress towards schistosomiasis elimination in China. In this paper, the endemic situation of schistosomiasis in Yangtze River Economic Belt areas and the possible impact on the schistosomiasis control were analyzed. In addition, a few suggestions were proposed for schistosomiasis control in Yangtze River Economic Belt areas.

Abstract
Objective: To validate whether the prognostic stage groups by the 8th edition of the American Joint Committee on Cancer (AJCC) staging system provides improved prognostic accuracy in T1-2N1M0 postmastectomy breast cancer patients compared to 7th edition. Methods: a total of 1 823 female patients with T1-2N1M0 breast cancer who underwent mastectomy and axillary lymph node dissection without neoadjuvant chemotherapy were analyzed and restaged according to 8th edition. Univariate analysis of prognostic factors was evaluated by using log-rank test. Multivariate analysis was estimated by using the Cox proportional hazards model. The prognostic accuracy of the two staging systems was compared using receiver operating characteristic (ROC) analyses and the concordance index (C-index). Results: 5-year locoregional recurrence rate (LRR) for the whole group was 6.0%, 5-year distant metastasis (DM) rate was 11.5%, 5-year disease-free survival (DFS) was 85.0%, and 5-year overall survival (OS) was 93.1%. Cox analysis showed that 7th edition of the AJCC staging system and progesterone receptor status were independent risk factors for LRR, DM, DFS and OS (P<0.05). Compared with stage by 7th edition, 1 278(70.1%) were assigned to a different prognostic stage group: 1 088 (85.1%) to a lower stage and 190 (14.9%) to a higher stage. LRR, DM, DFS and OS were significantly different between prognostic stage ⅠA, ⅠB, ⅡA, ⅡB and ⅢA according to 8th edition of the AJCC staging system(P<0.001). Prognostic stage had significantly higher C-indexes and provided better estimation of prognosis compared to stage by 7th edition of the AJCC staging system (P<0.001). Conclusion: The prognostic stage groups of 8th edition AJCC staging system has superior prognostic accuracy compared to 7th edition in T1-2N1M0 breast cancer, and has better clinical therapeutic guidance value.

Abstract
The Ising-like antiferromagnet α-CoV2O6 has received considerable interests because of stabilized 1/3 magnetization plateau around 5 K under magnetic field applied along magnetic easy c-axis. In this work, this magnetization plateau was studied by varying temperature or rotating magnetic field. As temperature decreased, this stabilized plateau collapsed, and additional magnetic transitions were observed. As a result, a rich magnetic phase diagram was constructed and extended to temperature lower than previously reported. When magnetic field moved from the c to b (or a) axis, the magnetization plateau developed with field directions and vanished finally when the field was restricted in the ab plane. An impressive observation is that this 1/3-plateau can be stabilized and remain robust even when magnetic field deviated from the c axis, accompanied by the evolutions of the magnetic moments and the critical transition fields. We suppose that the origins of these temperature and angular dependences of the 1/3 magnetization plateau are related to strong spin-orbital coupling. Indeed, electron spin resonance (ESR) measurement gives large Landé factor of 8.9, evidencing that there exists strong spin-orbital coupling.

Abstract
Objective: Investigate the causes of poor prognosis of mechanical thrombectomy in the time window of acute ischemic stroke (AIS) with anterior circulation. Methods: A retrospective analysis was made on the data of 78 patients with anterior circulation AIS who underwent mechanical thrombectomy in the time window from January 2017 to December 2017 in the Department of Vascular Neurosurgery of Liaocheng Brain Hospital. The modified Rankin scale (mRS) was used to evaluate the prognosis of the patients 3 months after operation. According to the prognosis,the patients were divided into the group with good prognosis (42 cases, mRS<2 points) and the group with poor prognosis (36 cases, mRS<3 points). Univariate and multivariate Logistic regression analysis was used to analyze the related factors of poor prognosis. Results: (1) Univariate analysis showed that the prognosis of patients with good combination and primary stenosis of diabetes mellitus and atherosclerosis was lower than that of patients with poor prognosis (P<0.05). The collateral circulation compensation rate and vascular recanalization rate of patients with good prognosis were higher than those of patients with poor prognosis (P<0.05). Learning significance (P<0.05). (2) Multivariate analysis showed that diabetes mellitus (P=0.035), collateral circulation compensation (P=0.011) and primary atherosclerotic stenosis (P=0.042) were independent risk factors for poor prognosis. Conclusion: Perfect preoperative evaluation and strict screening of patients, good collateral circulation compensation,individualized treatment for patients with primary atherosclerotic stenosis,and strict control of postoperative hyperglycemia can improve the clinical prognosis of endovascular therapy.

Abstract
Dr. Wang has engaged in surgery and burn medicine for 61 years. He is one of the first generation of burn doctor in China, who treated burn patients more than ten thousands and went to dozens of cities and areas to rescue the wounded near hundred batches. He made contribution to the establishment of Chinese special scheme for treating burn patients. He established the institute lab of metabolism and nutrition in 1985, and treated burn patients and carried out research of burn metabolism and nutrition simultaneously. He developed new theory that other routes like internal organs especially intestine besides burn wound can induce hypermetabolism i. e." enterogenous hypermetabolism" . If gut works, early feeding (EF) and enteral nutrition (EN) are better than delayed feeding and parenteral nutrition, and EN or EF can promote gastrointestinal resuscitation, reduce intestine injury, modulate hypothalamus and pituitary function, and decrease hypermetabolism. At the end of the 1980s, by measuring the resting energy expenditure of 105 adult burn patients and normal adults, they worked out the first formula for calories supply in Chinese burn adults. He published 340 papers, while 50 papers were exchanged in international meeting, and published 53 monographs (as editor or associate editor in chief for 9 books). Metabolism and Nutrition in Burns is the 1st burn metabolism and nutrition book in China. We got 24 awards of nation, army, and provincial and ministerial level in science, technology, medicine, and education, and there were two awards of " National 2nd Science and Technology Award" (respectively the 1st and 2nd author). He was the chairman of Burn Institute of Southwest Hospital during 1988-1999, and the institute was appraised as " Model Unit of Grass-roots in General Logistics Department" and awarded the 1st and the 2nd collective merits during that time. He was the vice president of Chinese Burn Association and chief editor of Chinese Journal of Burns.

Abstract
Objective: To investigate the value of fibrinogen to albumin ratio (FAR) at admission on predicting spontaneous recanalization of infarct-related artery (IRA) in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods: Clinical data from 255 acute STEMI patients ((61.1±11.2) years old, 189 males) who underwent emergency coronary angiography within 12 hours in our hospital from December 2015 to April 2018 were retrospectively analyzed. The acute STEMI patients were divided into non-spontaneous recanalization group (thrombolysis in myocardial infarction (TIMI) flow grade 0-1, 203 cases) and spontaneous recanalization group (TIMI flow grade 2-3, 52 cases). Multivariate logistic regression analysis was used to evaluate related factors of IRA spontaneous recanalization. The receiver operating characteristic (ROC) curve was used to evaluate the value of FAR in predicting spontaneous coronary recanalization. Results: There was no significant difference in age,gender, hypertension, diabetes, smoking,systolic blood pressure,diastolic blood pressure,heart rate, duration of chest pain, type of infarction, infarct-related artery, door-to-balloon time, and drug used before admission between non-spontaneous recanalization group and spontaneous recanalization group (all P>0.05). The FAR and high-sensitivity C-reactive protein levels were significantly lower in the spontaneous recanalization group than in the non-spontaneous recanalization group (8.20±1.85 vs. 11.02±2.75, P<0.001; (6.87±3.36) g/L vs. (8.51±3.72) g/L, P=0.004). Multivariate logistic regression analysis showed that FAR (OR=0.492, 95%CI 0.354-0.686, P<0.001), serum uric acid (OR=0.994, 95%CI 0.989-0.999, P=0.018) and high-sensitivity C-reactive protein (OR=0.774, 95%CI 0.614-0.975, P=0.030) were independent negative correlation with spontaneous recanalization of infarct-related artery in patients with acute STEMI. The ROC curve showed that the area under the curve of FAR predicting spontaneous recanalization of infarct-related artery in patients with acute STEMI was 0.807 (95%CI 0.630-0.758, P<0.001), and the diagnostic threshold was 9.26, the sensitivity was 76.9%, the specificity was 75.9%. Conclusion: The level of admission FAR has certain predictive value for spontaneous recanalization of infarct-related arteries in patients with acute STEMI.

Abstract
Objective: To investigate the clinical and prognostic differences between primary nasopharyngeal natural killer (NK)/T-cell lymphoma (NP NKTCL) and extranodal NK/T-cell lymphoma of the nasal cavity with nasopharynx extension (N-NP NKTCL). Methods: A total of 89 patients with NP NKTCL and 113 patients with N-NP NKTCL from January 2000 to June 2015 were retrospectively analyzed. Clinical and pathological features, treatment responses and prognosis were compared between the two groups. Results: NP NKTCL patients showed similar clinicopathological features with those with N-NP NKTCL, except that the former had a relative low proportion of elevated lactate dehydrogenase (LDH) levels (28.1% vs. 41.6%; P=0.001). Both of two groups presented with high proportion of cervical lymph node involvement (55.1% and 42.5%; P=0.076). The 5-year overall survival (OS) rates in these two groups were 63.2% and 54.6%, respectively, whereas 5-year progress-free survival (PFS) rates were 50.7% and 45.6%, respectively. For the patients with stage Ⅰ and Ⅱ, the 5-year OS and PFS rates in these two groups were 68.8% and 55.7% as well as 55.6% and 47.2%, respectively. These were no statistically significant differences between two groups (all P>0.05). The complete response (CR) rate after initial chemotherapy in NP NKTCL group was 43.8%, which was significant higher than that of 19.6% in N-NP NKTCL group (P=0.006). Additionally, the CR rate after primary radiotherapy was 63.4% and 62.7%, respectively (P=0.629). The NP NKTCL patients with stage Ⅰ and Ⅱ who accepted radiotherapy with or without chemotherapy had similar survival times with chemotherapy alone, showing the 5-year OS rates of 70.5% and 33.3% (P=0.238), as well as the 5-year PFS rates of 56.7% and 33.3%, respectively (P=0.431). Similar results were found in N-NP NKTCL group, the 5-year OS rates for patients with radiotherapy with or without chemotherapy and chemotherapy alone were 57.4% and 33.3% (P=0.246), while the 5-year PFS rates were 49.3% and 16.7% (P=0.177), respectively. Besides, the relapse pattern of NP NKTCL and N-NP NKTCL groups was also similar, mainly involving the distant extra-nodal organs followed by lymph nodes. Conclusion: The patients with N-NP NKTCL and NP NKTCL showed similar clinical and prognostic features, however, the initial response to chemotherapy was different.

Abstract
Glycogen Synthase Kinase-3 (GSK-3) is a constitutively dynamic, omnipresent serine/threonine protein kinase regularly called as a "multitasking kinase" due to its pliable function in diverse signaling pathways. It exists in two isoforms i.e., GSK-3α and GSK-3β. Inhibition of GSK-3 may be useful in curing various diseases such as Alzheimer's disease, type II diabetes, mood disorders, cancers, chronic inflammatory agents, stroke, bipolar disorders and so on, but the approach poses significant challenges. Lithium was the first GSK-3β inhibitor to be used for therapeutic outcome and has been effectively used for many years. In recent years, a large number of structurally diverse potent GSK-3β inhibitors are reported. The present review focuses on the recent developments in the area of medicinal chemistry to explore the diverse chemical structures of potent GSK-3β inhibitors and also describes its structure-activity relationships (SAR) and molecular binding interactions of favorable applicability in various diseases.

Abstract
BACKGROUND Previous studies suggest that dexmedetomidine has a protective effect against local anaesthetic-induced nerve injury in regional nerve blocks. Whether this potentially protective effect exists in the context of diabetes mellitus is unknown. METHODS A diabetic state was established in adult male Sprague-Dawley rats with intraperitoneal injection of streptozotocin. Injections of ropivacaine 0.5%, dexmedetomidine 20 μg kg-1 (alone and in combination), or normal saline (all in 0.2 ml) were made around the sciatic nerve in control and diabetic rats (n=8 per group). The duration of sensory and motor nerve block and the motor nerve conduction velocity (MNCV) were determined. Sciatic nerves were harvested at post-injection day 7 and assessed with light and electron microscopy or used for pro-inflammatory cytokine measurements. RESULTS Ropivacaine and dexmedetomidine alone or in combination did not produce nerve fibre damage in control non-diabetic rats. In diabetic rats, ropivacaine induced significant nerve fibre damage, which was enhanced by dexmedetomidine. This manifested with slowed MNCV, decreased axon density, and decreased ratio of inner to outer diameter of the myelin sheath (G ratio). Demyelination, axon disappearance, and empty vacuoles were also found using electron microscopy. An associated increase in nerve interleukin-1β and tumour necrosis factor-α was also seen. CONCLUSIONS Ropivacaine 0.5% causes significant sciatic nerve injury in diabetic rats that is greatly potentiated by high-dose dexmedetomidine. Although the dose of dexmedetomidine used in this study is considerably higher than that used in clinical practice, our data suggest that further studies to assess ropivacaine (alone and in combination with dexmedetomidine) use for peripheral nerve blockade in diabetic patients are warranted.

Abstract
Interatrial block (IAB) is associated with a multitude of medical conditions. The aim of this retrospective study was to investigate whether CHADS2 (congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, prior stroke) score is positively associated with the development of IAB. A total of 1072 patients (men, 555; women, 517; mean age, 61 ± 14 years) were included in the study. P-wave duration was measured manually using a caliper. IAB was defined as a P-wave duration of ≥ 120 ms on a 12-lead electrocardiogram. CHADS2 scores were calculated retrospectively. Among the 1072 patients, the prevalence of IAB was 36.1% (387/1072). In multivariate analysis, increased CHADS2 score (odds ratio [OR], 1.810; 95% confidence interval [CI], 1.577-2.077; P < 0.001), coronary artery disease (OR, 1.536; 95% CI, 1.065-2.216; P = 0.022), and increased left atrial diameter (OR, 1.039; 95% CI, 1.008-1.071; P = 0.013) were independently associated with IAB. The percentages of patients with IAB among those with a CHADS2 score of 0, 1, 2, 3, 4, 5, and 6 were 20.6%, 33.0%, 45.0%, 55.9%, 61.9%, 77.8%, and 100%, respectively (P < 0.001). There was a greater percentage of patients with a CHADS2 score of ≥ 2 with IAB compared with a CHADS2 score of < 2 (26.5% vsrsus 52.0%; P < 0.001). In receiver operating curve (ROC) analysis, CHADS2 score (area under the curve, 0.670; 95% CI, 0.636-0.704; P < 0.001) was predictive of IAB. In conclusion, CHADS2 score was significantly associated with the development of IAB in this study population.

Abstract
Objective: To investigate the reproductive health status of female workers in petrochemical industry, and to provide a reference for improving reproductive health status and developing preventive and control measures for female workers in petrochemical industry. Methods: A face-to-face questionnaire survey was performed from January to October, 2016. The Questionnaire on Women's Reproductive Health was used to investigate the reproductive health of female workers in petrochemical industry. The multivariate logistic regression model was used to identify the influencing factors for reproductive health of female workers in petrochemical industry. Results: Among the 7485 female workers, 1 268 (40.9%) had abnormal menstrual period, 1 437 (46.4%) had abnormal menstrual volume, 177 (28.5%) had hyperplasia of mammary glands, and 1 807 (24.6%) had gynecological inflammation. The reproductive system diseases in female workers in petrochemical industry were associated with the factors including age, marital status, education level, unhealthy living habits, abortion, overtime work, work shift, workload, video operation, occupational exposure, positive events, and negative events, and among these factors, negative events (odds ratio[OR]= 1.856) , unhealthy living habits (OR=1.542) , and positive events (OR=1.516) had greater impact on reproductive system diseases. Conclusion: Many chemical substances in the occupational environment of petrochemical industry can cause damage to the reproductive system, which not only affects the health of the female workers, but also poses potential threats to the health of their offspring. Occupational exposure, unhealthy living habits, overtime work, and work shift have great influence on reproductive system diseases in female workers.

Abstract
Objective:The aim of this study is to investigate the clinical features in patients with unilateral sinus disease.Method:A retrospective review of 2 480 patients who had undergone sinus surgery was performed. The clinical data were gathered and analyzed to investigate the features of the unilateral sinus disease. Descriptive and inferential statistics were computed.Result:1 350 patients (54.4%) who had bilateral sinus disease were all diagnosed as chronic rhinosinusitis pathologically confirmed after surgery. Unilateral sinus disease was identified in 1 130 patients (45.6%) and the disease entities were categorized as chronic rhinosinusitis (589 patients, 52.1%), fungal rhinosinusitis (312 patients, 27.6%), inverted papilloma (95 patients, 8.4%), sinus cyst (78 patients, 6.9%), malignant tumor (34 patients, 3%), osteoma including osteodysplasia fibrosa (11 patients, 1%) and others (11 patients, 1%) . Among the patients of malignant tumor, there were 13 cases of squamous cell carcinoma, 6 cases of malignant lymphoma, 4 cases of sarcoma, 4 cases of melanoma, 3 cases of adenocystic carcinoma, 1 case of verrucous carcinoma, 1 case of metastases from liver, 1 case of plasmacytoma,and 1 case of hemangiopericytoma. The number of fungal rhinosinusitis patient increased year by year. The common major presenting symptom for fungal rhinosinusitis was headache (46.8%) and bloody discharge (31.1%). Male accounted for a large part of both inverted papilloma and malignant tumor patients, both of which CT findings that correlated with the presence was the absorption and destruction of the sinus wall. Thirty-one cases (32.6%) of inverted papilloma patients recurred. Bloody discharge (58.8%) was major symptom of the malignant tumor.Conclusion:There were almost a half of unilateral sinus diseases that were not common chronic rhinosinusitis, in which the incidence of fungal rhinosinusitis, inverted papilloma, squamous cell carcinoma and other kinds of benign and malignant tumor was high. A careful history taking and endoscopic examination play a key role as well as imaging examination in identifying unilateral sinus disease, which is important for reaching a correct diagnosis and treatment.

Abstract
Calpain 9 (CAPN9) is expressed in the stomach and small intestine. CAPN9 has regulatory roles in hypertension, heart disease, gastric mucosal defense, and kidney disease. The involvement of CAPN9 has not been reported in the development of chickens. CAPN9 mRNA was found in adipose and muscle tissue in this study. Two linkage single nucleotide polymorphisms (SNP; G7518A and C7542G) in intron 4 were screened from 160 birds of the D2 chicken line. The 2 mutation sites were associated with carcass weight, evisceration weight, abdominal fat weight (AFW), abdominal fat percentage (AFP), and breast muscle percentage (all P < 0.05). Intramuscular fat (IMF) content was not significantly different in the 3 genotypes. But, the AA(7518)/GG(7542) genotype had the highest IMF content, highest breast muscle weight, and lower AFW and AFP. Moreover, the mRNA level of CAPN9 in abdominal fat tissue was significantly different (P < 0.05 or P < 0.01) between any 2 genotypes, consistent with AFW and AFP. In summary, the expression of CAPN9 in adipose and breast muscle tissue is reported for the first time. CAPN9 affected production performance of chickens. As a marker, the linkage G7518A and C7542G polymorphisms in intron 4 of CAPN9 could affect the production traits by regulating mRNA expression. The findings concerning the marker enrich the theoretical foundation for molecular breeding of high-quality broilers.

Abstract
Objective: To investigate the overall efficacy of early breast cancer after breast-conserving treatment. To analyze risk factors affecting local regional recurrence (LRR), distant metastasis (DM) and survival. Methods: 1 791 breast cancer patients treated with breast-conserving surgery were retrospectively analyzed. The inclusion criteria were pathologic diagnosis of invasive breast cancer without supraclavicular and internal mammary node metastasis, T1-2N0-3M0, and no neoadjuvant therapy. Univariate analysis of survival was performed by Kaplan-Meier method and log rank test. Cox regression model was used for multivariate analysis. Results: The median follow-up time was 4.2 years. For all patients, the 5-year LRR, DM, disease-free survival(DFS) and overall survival(OS) rates were 3.6%, 4.6%, 93.0% and 97.4%, respectively. The LRR rates of patients with Luminal A, Luminal B1, Luminal B2, HER-2 over-expressed and triple-negative breast cancer were 2.0%, 6.1%, 5.9%, 0 and 10.0%, while the DM rates were 3.2%, 6.7%, 8.3%, 4.8% and 7.3%, respectively. Among the N0 patients, axillary dissection was performed in 689 cases and sentinel lymph node biopsy in 652 cases. The 5-year LRR rates were 3.3% and 3.2% (P=0.859), and the OS rates were 98.2% and 98.3% (P=0.311) respectively, which showed no statistically significant. There were 1 576 patients that underwent postoperative radiotherapy. Postoperative radiotherapy significantly reduced the 5-year LRR compared with surgery alone (2.5% vs 12.9%). The 5-year LRR rates of patients who received conventional fractionated radiotherapy and hypo-fractionated radiotherapy were 2.7% and 3.1%, respectively. But the difference was not statistically significant (P=0.870). Multivariate analysis showed that age, lymphovascular invasion, pathological T staging, postoperative radiotherapy, ER/PR status and endocrine therapy were independent factors of LRR in breast cancer patients (all P<0.05). Histological grade and pathological N staging were independent factors of DM (all P<0.05). The age, lymphovascular invasion, pathological T and N staging, postoperative radiotherapy, ER/PR status and endocrine therapy were independent factors for DFS (all P<0.05). Histological grade, pathological N staging, ER/PR status and endocrine therapy were factors for OS (all P<0.05). Conclusions: With contemporary standard treatment, the recurrence rate of early breast cancer after breast conserving treatment is less than 10%. Node-negative patients after sentinel lymph node biopsy did not need axillary dissection. The overall utilization of radiotherapy after breast conserving surgery is satisfactory. Hypofractionated radiotherapy is as effective as conventional fractionated radiotherapy. Local regional recurrence and distant metastasis have different risk factors.

Abstract
The present work has systematically investigated the evolution of dispersoids and elevated-temperature properties including strength and creep resistance during various multi-step heat treatments in Al-Mn-Mg 3004 alloys. Results show that only the α-Al(MnFe)Si dispersoid is observed in the studied temperature range (up to 625 °C), and that it coarsens with increasing temperature to 500 °C, but dissolves at 625 °C. The evolution of elevated-temperature strength and creep resistance is greatly related to the temperature of each step during the multi-step heat treatments. Generally, lower temperature at the first-step heat treatment leads to higher properties, while the properties decrease with increasing temperature of last-step heat treatment. Suitable models have been introduced to explain the evolution of strength and the creep threshold stress at elevated-temperatures during the various heat treatments.

Abstract
Objective: To analyze the clinical features and prognosis of the ipsilateral breast tumor recurrence (IBTR) after breast conserving surgery. Methods: From 1999 to 2013, 63 women with IBTR after breast conserving surgery were retrospectively reviewed. All patients had adequate information on tumor location both at first presentation and at recurrence, with or without regional recurrence or distant metastasis. The histologic changes between true local recurrence and elsewhere recurrence groups were compared. The local recurrence, the overall survival after IBTR (IBTR-OS), the disease-free survival after IBTR (IBTR-DFS) were also compared. Results: All patients had undergone lumpectomy, including 38 cases with additional axillary lymph node dissection and 13 cases with sentinel lymph node biopsy. There were 11.3% (7/63) cases received neoadjuvant systemic therapy, 68.3% (43/63) had adjuvant radiotherapy, 60.3% (38/63) underwent adjuvant chemotherapy and 47.6% (30/63) received hormonal therapy. Forty-five cases (71.4%) had recurrence in the same quadrant, and 18 cases (28.6%) had elsewhere recurrence. Compared with histology at presentation, 10.3% of the patients (6/58) had different ones at recurrence and 28.9% of patients (13/45) had different molecular subtypes. The conversion rate of estrogen receptor status (33.3% vs 9.5%, P=0.012) and progesterone receptor status (56.3% vs 19.0%, P=0.005) in patients with elsewhere recurrence was significantly higher than that in patients with same quadrant recurrence. Fifty-nine cases had undergone surgery after IBTR, with 48 cases of secondary breast-conserving surgery and 11 cases of salvage mastectomy. The median time to IBTR of same quadrant recurrence and elsewhere recurrence groups were 26 months and 62 months (P=0.012), respectively. There were 84.4% and 44.4% cases who had local recurrence within 5 years after breast conserving surgery, respectively. Of all cases, the overall 5-year IBTR-OS and 5-year IBTR-DFS rates were 79.4% and 60.4%, respectively. There were no significant differences in 5-year IBTR-OS (77.4% vs. 83.6%, P=0.303) or 5-year IBTR-DFS (60.0% vs. 62.8%, P=0.780) between same quadrant recurrence and elsewhere recurrence groups. Univariate analysis showed that pN0-1 (P<0.001), luminal subtype (P=0.026), adjuvant endocrine therapy (P=0.007) at first presentation, recurrent tumor < 3 cm (P=0.036) and having surgery after IBTR(P=0.002) were favorable factors of IBTR-OS. pN0-1 (P<0.001) at first presentation, recurrent tumor stage Ⅰ-Ⅱ (P<0.001) and having surgery after IBTR(P=0.001) were favorable factors of IBTR-DFS. There was no significant difference between second breast-conserving surgery and salvage mastectomy in IBTR-OS and IBTR-DFS (P>0.05). Conclusions: The IBTR after breast conserving surgery mainly occurred at the original quadrant. Second breast-conserving surgery did not affect patient's prognosis. There were significant differences in biological features between the same quadrant recurrence and elsewhere recurrence, requiring different therapeutic strategies in the future.
