Abstract
PURPOSE The purpose of this study was to explore the expression and potential mechanism of hsa_circ_0005397 in hepatocellular carcinoma progression. METHODS Quantitative reverse transcription-polymerase chain reaction(qRT-PCR) was used to measure the expression level of hsa_circ_0005397 and EIF4A3 from paired HCC tissues and cell lines. Western Blot (WB) and immunohistochemistry (IHC) were used to verify the protein level of EIF4A3. The specificity of primers was confirmed by agarose gel electrophoresis. Receiver Operating Characteristic (ROC) Curve was drawn to analyze diagnostic value. Actinomycin D and nuclear and cytoplasmic extraction assays were utilized to evaluate the characteristics of hsa_circ_0005397. Cell Counting kit-8 (CCK-8) and colony formation assays were performed to detect cell proliferation. Flow cytometry analysis was used to detect the cell cycle. Transwell assay was performed to determine migration and invasion ability. RNA-binding proteins (RBPs) of hsa_circ_0005397 in HCC were explored using bioinformatics websites. The relationship between hsa_circ_0005397 and Eukaryotic Translation Initiation Factor 4A3 (EIF4A3) was verified by RNA Binding Protein Immunoprecipitation (RIP) assays, correlation and rescue experiments. RESULTS In this study, hsa_circ_0005397 was found to be significantly upregulated in HCC, and the good diagnostic sensitivity and specificity shown a potential diagnostic capability. Upregulated expression of hsa_circ_0005397 was significantly related to tumor size and stage. Hsa_circ_0005397 was circular structure which more stable than liner mRNA, and mostly distributed in the cytoplasm. Upregulation of hsa_circ_0005397 generally resulted in stronger proliferative ability, clonality, and metastatic potency of HCC cells; its downregulation yielded the opposite results. EIF4A3 is an RNA-binding protein of hsa_circ_0005397, which overexpressed in paired HCC tissues and cell lines. In addition, expression of hsa_circ_0005397 decreased equally when EIF4A3 was depleted. RIP assays and correlation assay estimated that EIF4A3 could interacted with hsa_circ_0005397. Knockdown of EIF4A3 could reverse hsa_circ_0005397 function in HCC progression. CONCLUSIONS Hsa_circ_0005397 promotes progression of hepatocellular carcinoma through EIF4A3. These research findings may provide novel clinical value for hepatocellular carcinoma.

Abstract
A BaTiO3/SrCoO2.5 (BTO/SCO) bilayer and a BTO single film were prepared by radio frequency magnetron sputtering on La0.7Sr0.3MnO3 (LSMO) buffered SrTiO3 (001) substrates. Interestingly, compared with reported BTO-based films, the BTO/SCO/LSMO heterostructure has a maximum ON/OFF current ratio of ∼945. More interestingly, compared with the BTO single layer, a larger Pr (∼18.4 μC cm-2) and larger dielectric tunability (∼71.9%) were achieved in the BTO/SCO bilayer. The improved performance may be attributed to the large tetragonality and improved oxygen vacancy concentrations in the BTO/SCO/LSMO heterostructure. Furthermore, our BTO/SCO/LSMO stacks exhibit potential for flexible electronic informational devices.

Abstract
The scientific setting and standardized management of adult vaccination clinics will improve the accessibility of vaccination services, thereby increasing the vaccination rate. Currently, some provinces and cities in China have been exploring the construction of adult vaccination systems for many years, effectively improving the level of vaccination services, and forming some useful experiences and models. However, the construction of China's adult vaccination system is not yet perfect, and the service mode needs to be optimized. In the future, we should continue to improve the guarantee measures for adult vaccination, scientifically lay out the network, optimize the service mode, and improve the overall quality of immunization services over the life course.

Abstract
BACKGROUND Liver cancer resection, especially in patients with hemihepatectomy or extended hemihepatectomy, often leads to poor prognosis, such as liver insufficiency and even liver failure and death, because the standard residual liver volume (SRLV) cannot be fully compensated after surgery. AIM To explore the risk factors of poor prognosis after hemihepatectomy for hepatocellular carcinoma and evaluate the application value of related prognostic approaches. METHODS The clinical data of 35 patients with primary liver cancer in Nantong Third People's Hospital from February 2016 to July 2020 were retrospectively analyzed. The receiver operating characteristic curve was created using medcac19.0.4 to compare the critical values of the SRLV in different stages of liver fibrosis after hemihepatectomy with those of liver dysfunction after hemihepatectomy. It was constructed by combining the Child-Pugh score to evaluate its application value in predicting liver function compensation. RESULTS The liver stiffness measure (LSM) value and SRLV were associated with liver dysfunction after hemihepatectomy. Logistic regression analysis showed that an LSM value ≥ 25 kPa [odds ratio (OR) = 6.254, P < 0.05] and SRLV ≤ 0.290 L/m2 (OR = 5.686, P < 0.05) were independent risk factors for postoperative liver dysfunction. The accuracy of the new liver reserve evaluation model for predicting postoperative liver function was higher than that of the Child-Pugh score (P < 0.05). CONCLUSION SRLV and LSM values can be used to evaluate the safety of hemihepatectomy. The new liver reserve evaluation model has good application potential in the evaluation of liver reserve function after hemihepatectomy.

Abstract
Introduction: Diquat poisoning leads to kidney injury, hepatotoxicity, rhabdomyolysis, gastrointestinal hemorrhage, and respiratory failure. Diquat has high mortality and no specific antidote. The pathology of acute kidney injury caused by diquat poisoning has been mainly investigated in animal studies and autopsies, and typically shows renal tubular necrosis. To our knowledge, antemortem renal biopsy has not been reported in humans.Case reports: Two males and one female presented following deliberate diquat self-poisoning. Their main clinical manifestations were abdominal pain, nausea, and emesis. All developed acute kidney injury. Kidney biopsy was performed in two cases which showed acute tubular necrosis with renal interstitial edema and multifocal inflammatory cell infiltration. Treatments given included gastric lavage, catharsis, early hemoperfusion combined with continuous kidney replacement therapy or hemodialysis, administration of glucocorticoids, and antioxidant therapy. All patients survived.Discussion: Despite potentially lethal ingestions three patients survived oral diquat poisoning with intensive supportive care. No clear relationship can be made between any of the therapies given and patient outcome.Conclusions: Kidney biopsy in these patients confirmed proximal renal tubular injury was the major pathological finding although interstitial injury was also present. The role of therapies that address renal pathology requires further study.

Abstract
Background Hepatocellular carcinoma (HCC) accounts for the majority of primary liver cancers. Worldwide, liver cancer is the fourth most common cause of cancer-related death. Recent studies have found that PIWI-interacting RNAs (piRNAs) participate in the occurrence and development of various tumors and are closely related to the growth, invasion, metastasis and prognosis of malignant tumors. Studies on the role and functional mechanism of piRNAs in HCC development and progression are limited. Methods Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) were used to detect the expression of piR-017724 in both HCC tissues and cells. Based on the clinical data of HCC patients, the clinical and prognostic value of piR-017724 was further analyzed. Then, targeted silencing and overexpressing of piR-017724 in HCC cells was further used to examine the biological functions of piR-017724. In addition, the downstream target protein of piR-017724 was predicted and validated through high-throughput sequencing and public databases. Results The piR-017724 was significantly downregulated in HCC tissues and cells, and the downregulation of piR-017724 was associated with tumor stage and poor prognosis in HCC. The piR-017724 inhibitor promoted the proliferation, migration and invasion of HCC cells, while the piR-017724 mimic had the opposite effect. However, the piR-017724 did not affect apoptosis of HCC cells. High-throughput sequencing and qRT-PCR confirmed a reciprocal relationship between piR-017724 and PLIN3. Therefore, we speculate that piR-017724 may inhibit the development and progression of HCC by affecting the downstream protein PLIN3. Conclusions Our study shows that piR-017724, which is lowly expressed in HCC, inhibits the proliferation, migration and invasion of HCC cells and may affect the development of hepatocellular liver cancer through PLIN3, which provides new insights into the clinical application of piR-017724 in the treatment of hepatocellular carcinoma.

Abstract
With the expansion of mpox virus infection from endemic to a global epidemic in 2022, the WHO declared that the mpox event constituted a Public Health Emergency of International Concern. Due to the high degree of gene sequence similarity among orthopox viruses and cross-reactive antibodies induced by orthoviruses, smallpox vaccination may affect the immune response induced by mpox virus infection. The analysis of the protective effects of smallpox vaccination against mpox virus infection will help define the focus of prevention and control. In this review, we clarify the protection of the smallpox vaccine against mpox virus infection by analyzing the correlation between smallpox vaccination, immune response status, and clinical data and providing evidence for the prevention, control, and strategies of mpox epidemics.

Abstract
BackgroundThe development of antimicrobial resistance in the opportunistic pathogen Escherichia coli has become a global public health concern. Due to daily close contact, dogs kept as pets share the same E. coli with their owners. Therefore, the detection of antimicrobial resistance in canine E. coli is important, as the results could provide guidance for the future use of antibiotics. This study aimed to detect the prevalence of antibiotic-resistance of canine origin E. coli in Shaanxi province and to explore the inhibition effect of magnolol combined with cefquinome on MDR E. coli, so as to provide evidence for the use of antibiotics.MethodsCanine fecal samples were collected from animal hospitals. The E. coli isolates were separated and purified using various indicator media and polymerase chain reaction (PCR). Drug-resistance genes [aacC2, ant(3')-I, aph(3')-II, aac(6')-Ib-cr, aac(3')-IIe, blaKPC, blaIMP−4, blaOXA, blaCMY, blaTEM−1, blaSHV, blaCTX−M−1, blaCTX−M−9, Qnra, Qnrb, Qnrs, TetA, TetB, TetM, Ermb] were also detected by PCR. The minimum inhibitory concentration (MIC) was determined for 10 antibiotics using the broth-microdilution method. Synergistic activity of magnolol and cefquinome against multidrug-resistant (MDR) E. coli strains was investigated using checkerboard assays, time-kill curves, and drug-resistance curves.ResultsA total of 101 E. coli strains were isolated from 158 fecal samples collected from animal hospitals. MIC determinations showed that 75.25% (76/101) of the E. coli strains were MDR. A total of 22 drug-resistance genes were detected among the 101 strains. The blaTEM−1gene exhibited the highest detection rate (89.77%). The TetA and Sul gene also exhibited high detection rate (66.34 and 53.47%, respectively). Carbapenem-resistant E. coli strains were found in Shangluo and Yan'an. Additionally, in MDR E. coli initially resistant to cefquinome, magnolol increased the susceptibility to cefquinome, with an FICI (Fractional Inhibitory Concentration Index) between 0.125 and 0.5, indicating stable synergy. Furthermore, magnolol enhanced the killing effect of cefquinome against MDR E. coli. Resistance of MDR E. coli to cefquinome decreased markedly after treatment with magnolol for 15 generations.ConclusionOur study indicates that antibiotic-resistance E. coli has been found in domestic dogs. After treatment with magnolol extracted from the Chinese herb Houpo (Magnolia officinalis), the sensitivity of MDR E. coli to cefquinome was enhanced, indicating that magnolol reverses the resistance of MDR E. coli. The results of this study thus provide reference for the control of E. coli resistance.

Abstract
Objective: To investigate the expression and role of asparte-specific cysteine protease (Caspase)-1, inflammasomes key molecule, in hepatitis B virus (HBV)-related diseases. Methods: HBV-related liver disease patients' serum (438 cases) and liver tissue (82 cases) samples were collected from Beijing You'an Hospital affiliated with Capital Medical University. The mRNA expression level of caspase-1 in liver tissue was detected by real-time fluorescence quantitative PCR (qRT-PCR). The protein expression level of Caspase-1 in liver tissue was detected by the immunofluorescence method. The activity of Caspase-1 was detected using the Caspase-1 colorimetric assay kit. The level of Caspase-1 in the serum was detected by an ELISA kit. Results: The results of qRT-PCR showed that the mRNA level of Caspase-1 was downregulated in patients with chronic hepatitis B (CHB), cirrhosis (LC), and hepatocellular carcinoma (HCC), while up-regulated in patients with acute-on-chronic liver failure (ACLF) (P<0.01) compared with normal subjects. Immunofluorescence assays showed that Caspase-1 protein levels were elevated in ACLF patients, decreased in HCC and LC patients, and slightly elevated in CHB patients. The activity of Caspase-1 was slightly higher in liver tissue from CHB, LC, and HCC patients than in the normal control group, and there was no statistically significant difference between the groups. Additionally, compared with the control group, Caspase-1 activity was significantly reduced in the ACLF group (P<0.01). Serum Caspase-1 levels were significantly lower in patients with CHB, ACLF, LC, and HCC than in normal subjects, and serum Caspase-1 levels were lowest in patients with ACLF (P<0.001). Conclusion: Caspase-1, a key molecule of inflammasomes, plays an important role in HBV-related diseases and has significant differences, showing distinct features for ACLF than other HBV-related diseases.

Abstract
Objective: To evaluate the recognition of acute respiratory infection (ARI) by a pretrained model based on electronic medical records (EMRs). Methods: 38 581 EMRs were obtained from Chongqing University Three Gorges Hospital in December 2021. Bidirectional encoder representation from transformers (BERT) pretrained model was used to identify ARI in EMRs. The results of medical professionals were considered as the gold standard to calculate the sensitivity, specificity, Kappa value, and area under the curve of the receiver operating characteristic (AUC). Results: There were 3 817 EMRs in the test set, with 1 200 ARIs. A total of 1 205 cases were determined as ARI by the model, with a sensitivity of 92.67% (1 112/1 200) and a specificity of 96.45% (2 524/2 617). The model identified ARI with similar accuracy in males and females (AUCs 0.95 and 0.94, respectively), and was more accurate in identifying ARI cases in those aged less than 18 than in adults 18-59 and adults 60 and older (AUCs 0.94, 0.89 and 0.94, respectively). The current model had a better identification of ARIs in outpatient patients than that in hospitalized patients, with AUCs of 0.74 and 0.95, respectively. Conclusion: The use of the BERT pretrained model based on EMRs has a good performance in the recognition of ARI cases, especially for the outpatients and juveniles. It shows a great potential to be applied to the monitoring of ARI cases in medical institutions.

Abstract
The incidence and mortality of cancer are increasing each year. At present, the sensitivity and specificity of the blood biomarkers that were used in clinical practice are low, which make the detection rate of cancer decrease. With advances in bioinformatics and technology, some non-coding RNA as biomarkers can be easily detected through some traditional and new technologies. Circular RNAs (circRNAs) are non-coding RNAs, that is, they do not encode proteins, and have important regulatory functions. CircRNAs can remain stable in bodily fluids, such as in saliva, blood, urine, and especially plasma. The difference in the expression of plasma circRNAs between cancer patients and normal people may suggest that plasma circRNAs may play an important role in the occurrence and development of cancer. In this review, we summarized the clinical effect of plasma circRNAs in several high-incidence cancers. CircRNAs may be effective biomarkers for tumour diagnosis, treatment selection and prognosis evaluation.

Abstract
Objective: To rapidly evaluate the level of healthcare resource demand for laboratory testing and prevention and control of corona virus disease 2019 (COVID-19) in different epidemic situation, and prepare for the capacity planning, stockpile distribution, and funding raising for infectious disease epidemic response. Methods: An susceptible, exposed, infectious, removed infectious disease dynamics model with confirmed asymptomatic infection cases and symptomatic hospitalized patients was introduced to simulate different COVID-19 epidemic situation and predict the numbers of hospitalized or isolated patients, and based on the current COVID-19 prevention and control measures in China, the demands of resources for laboratory testing and prevention and control of COVID-19 were evaluated. Results: When community or local transmission or outbreaks occur and total population nucleic acid testing is implemented, the need for human resources is 3.3-89.1 times higher than the reserved, and the current resources of medical personal protective equipment and instruments can meet the need. The surge in asymptomatic infections can also increase the human resource demand for laboratory testing and pose challenge to the prevention and control of the disease. When vaccine protection coverage reach ≥50%, appropriate adjustment of the prevention and control measures can reduce the need for laboratory and human resources. Conclusions: There is a great need in our country to reserve the human resources for laboratory testing and disease prevention and control for the response of the possible epidemic of COVID-19. Challenges to human resources resulted from total population nucleic acid testing and its necessity need to be considered. Conducting non-pharmaceutical interventions and encouraging more people to be vaccinated can mitigate the shock on healthcare resource demand in COVID-19 prevention and control.

Abstract
Objective: To analysis the clinical characteristics and to summarize therapy experience of pediatric patients with cardiac syncope caused by anomalous origin of the left coronary artery from the right sinus (ALCA-R). Methods: We retrospectively analyzed the clinical data including clinical manifestations, myocardial injury biomarkers, radiological features, treatments and prognoses of pediatric patients with ALCA-R who were admitted to Beijing Children's Hospital from November 2015 to June 2018. Results: Four female patients were included in this analysis, age of onset was 7 to 14 years. All the patients presented with exercise-induced syncope and acute myocardial infarction. During the course, three patients presented with acute left heart failure, and one patient had history of sudden cardiac arrest. Laboratory data showed significant elevation of both the creatine kinase and troponin levels in four patients. All electrocardiogram (ECG) showed left main coronary artery occlusion, echocardiography suggested the possible anomalous origin of the left coronary artery in one child. Coronary CT angiography (CTA) revealed there was no coronary ostium in the left coronary sinus, and the left coronary artery had an anomalous origin from the right sinus. The left main coronary artery passed between the ascending artery and the root of the main pulmonary artery, which was compressed by these two large vessels. Two patients underwent cardiac magnetic resonance examination, which detected late gadolinium enhancement in ALCA-R with an interarterial course. Unroofing of the left coronary ostium (cut-back procedure) was performed in two patients, and the other two patients who were not operated were recommended to restrict their physical activities. During a regular follow-up period of 12-43 months, all the children survived without recurrent cardiovascular event. Conclusion: If an adolescent presents with exercise-induced syncope, acute myocardial infarction and even sudden death, and ECG shows left main coronary artery occlusion characteristics, we should consider the possibility of developmental abnormality of coronary artery, particularly the ALCA-R. Once diagnosed as ALCA-R, patients should be recommended to avoid strenuous activities,early recognition and surgical treatment are imperative for these patients.

Abstract
Objective: To investigate the clinical features and improve the diagnosis and treatment of anomalous origin of the left coronary artery from the right coronary sinus with an interarterial course (ALCA-R-IAC) between the ascending aorta and main pulmonary artery in children. Methods: A retrospective analysis of the clinical manifestation, laboratory test, radiological feature, treatment and prognosis were conducted in four female children presented with ALCA-R-IAC in Beijing Children's Hospital from November 2015 to June 2018. Results: The four girls with onset age of 7.5-14.7 years were diagnosed with ALCA-R-IAC by CT coronary angiography (CTCA). Four children presented with exercise-induced syncope and clinical manifestations of acute myocardial infarction including 3 patients with acute left heart failure, 1 cardiogenic shock and 1 cardiac arrest. Nervous system involvement was found in one patient. Troponin I increased significantly to 20.65-50.00 μg/L in the four patients. Electrocardiogram (ECG) developed signs of left main coronary artery involvement. Echocardiography revealed reduced left ventricular ejection fraction (LVEF) of 25%-45% in three children and suspected anomalous origin of the left coronary artery in one child. CTCA showed an anomalous left coronary artery originating from the right coronary sinus, which had an interarterial course between the aorta and pulmonary artery leading to a slim left main coronary trunk. Two children underwent unroofing procedure and the other two children in whom physical activities were restricted received conservative managements. During a regular follow-up period of 12-43 months, all the children survived without recurrent symptoms and had good prognosis. Conclusions: ALCA-R-IAC can present as exercise-related syncope and acute myocardial infarction, even sudden death in children and adolescents. CTCA is helpful to clarify the early diagnosis of ALCA-R-IAC. Surgical intervention is the main treatment for ALCA-R-IAC and strenuous physical activities should be avoided.

Abstract
Abstract
The study aimed to investigate the regulatory effect of miR-146a in proliferation, invasion and migration of breast cancer and its possible mechanism via NM23-H1. The expression levels of miR-146a in breast cancer with different pathological classification were significantly increased, while the expression levels of NM23-H1 were significantly decreased, which were closely correlated. Double luciferase reporter gene was used to verify the target regulatory relationship between miR-146 and NM23-H1 on a human breast cancer cell line. miR-146a was closely related to the proliferation and metastasis of breast cancer. miR-146a also promoted the growth of breast cancer in vivo via targeting NM23-H1. In conclusion, miR-146 can promote the proliferation and invasion of breast cancer by targeting NM23-H1.

Abstract
Objective: To explore the effect of induced labor on delivery outcome of pregnant women undergoing vaginal trial of labor after cesarean section. Methods: Totally, 173 pregnant women undergoing vaginal trial of labor after cesarean from April 1st, 2016 to October 31st, 2017 were involved. According to whether or not induced labor, pregnant women were divided into induced labor group (n=47) and natural labor group (n=126). The two groups of the general situation, the situation of delivery and delivery outcome were compared. Further more, the induced labor group were divided into cesarean section patients (n=20) and vaginal delivery patients (n=27) based on pregnancy outcomes, induction situation and delivery situation were analyzed. Results: (1) The gestational weeks was 39.2±1.1 in induced labor group, 38.7±1.0 in natural labor group. The 1-minute Apgar score was 9.98±0.15 in induced labor group, and 9.87±0.60 in natural labor group. The neonatal weight was (3 497±426) g in induced labor group, and (3 288±350) g in natural labor group. The thickness of lower uterine segment at 36-39 weeks of pregnancy was (2.4±0.6) mm in induced labor group, (2.1±0.6) mm in natural labor group. There were obviously differences in the gestational week, the 1-minute Apgar score, the neonatal weight and the thickness of lower uterine segment at 36-39 weeks of pregnancy between the two groups (all P<0.05). There were no significant differences in 5-minute Apgar score, the interval between previous cesarean delivery, postpartum hemorrhage, fetal distress, and intrauterine infection, secondary uterine inertia, placental abruption and uterine ruption between the two groups (all P>0.05). (2) In induced labor group, the cervical score of cesarean section patients was 3.8±1.7, while the cervical score of vaginal delivery patients was 5.2±1.7. The induced labor days of cesarean section patients was (1.6±0.9) days, while the induced labor days of vaginal delivery patients was (1.2±0.4) days. There were obviously differences in the cervical score and the induced labor days among the two subgroup patients (all P<0.05). There were no significiant differences in Apgar score, neonatal weight, the thickness of lower uterine segment at 36-39 gestational weeks and the interval times of previous cesarean delivery between the two subgroup patients (P>0.05). Conclusion: Induction of labor does not reduce neonatal Apgar score, and does not increase the incidence of postpartum complications, and eliminats the increase of cesarean section rate caused by increased gestational weeks and fetal enlargement, and increases the vaginal delivery rate of pregnant women undergoing vaginal trail of labor after cesarean section.

Abstract
Objective: To investigate the clinical efficacy of laparoscopic subtotal colonic bypass plus colostomy with antiperistaltic cecoproctostomy (SCBCAC) in the treatment of senile slow transit constipation. Methods: A retrospective cohort study was performed. Clinical data of 30 colonic slow transit constipation patients aged ≥70 years old undergoing laparoscopic SCBCAC from July 2012 to October 2016 (bypass plus colostomy group), and 28 patients undergoing laparoscopic subtotal colonic bypass with antiperistaltic cecoproctostomy (SCBAC) from February 2009 to June 2012 (bypass group) at our institute were collected. Efficacy was compared between the two procedures. Inclusion criteria: (1) meeting the Rome III diagnosis criteria for constipation; (2) confirmed diagnosis of slow transit constipation; (3) age ≥ 70 years old; (4) receiving non-surgical treatment for more than 5 years, and Wexner constipation score > 15; (5) follow-up for more than 2 years. Those with psychiatric symptoms or previous psychiatric history, obvious signs of outlet obstructive constipation, organic diseases of the colon and life-threatening cardiovascular diseases or cancer were excluded. In the bypass plus colostomy group, laparoscopy was performed via five trocars. The ileocecal junction and the ascending colon were mobilized and the ileocecal junction was pulled down to the pelvic inlet. The ascending colon was transected and the appendix was excised. The lateral peritoneum of the sigmoid colon and the rectal mesentery were dissected and the upper rectum was transected. The avil of a circular stapler was placed in the bottom of the cecum. The shaft of the stapler was placed in the rectum via the anal canal to complete end-to-side anastomosis (end rectum to lateral cecum). The end of the rectal-sigmoid colon was used for colostomy via an extraperitoneal approach to complete the operation. The following efficacy indexes were collected before surgery and 3, 6, 12, and 24 months after surgery: the number of daily bowel movements, the Wexner incontinence scale (WIS, 0-20, the lower the better), the Wexner constipation scale (WCS, 0-30, the lower the better), the gastrointestinal quality of life index (GIQLI, 0-144, the higher score, the better), abdominal pain intensity indicated by the numerical rating scale (NRS, 0-10, the lower score, the better), and the abdominal bloating score (ABS, 0-4, the lower score, the better). The complications defined as Clavien-Dindo class II or above were observed and recorded. Results: No significant differences in preoperative WCS, WIS, GIQLI, NRS, and ABS were observed between bypass plus colostomy group and bypass group (all P>0.05). All the patients successfully underwent laparoscopic surgery and no patient in either group experienced postoperative fecal incontinence. WCS and GIQLI were significantly improved (all P<0.001) at 3, 6, 12, and 24 months after surgery in both groups. At 12 months after surgery, the number of bowel movements was significantly less in bypass plus colostomy group than that in bypass group [(2.4±0.7) times vs. (3.4±1.2) times, t=4.048, P<0.001]. At 3, 6, 12 and 24 months after surgery, the improvement of GIQLI in bypass plus colostomy group was significantly better than that in bypass group (all P<0.001). At 24 months after surgery, GIQLI in bypass plus colostomy group and bypass group was 122.3±5.3 and 92.8±16.6, respectively, with a significant difference (t=9.276, P<0.001). At 12 and 24 months after surgery, NRS in bypass plus colostomy group was significantly better than that in bypass group (both P<0.001). At 24 months after surgery, NRS in bypass plus colostomy group was 0.9±0.7, while that in bypass group was 3.7±2.7. There was a significant difference between two groups (t=5.585, P<0.001). At 6, 12 and 24 months after surgery, the improvement of ABS in bypass plus colostomy group was also significantly better than that in bypass group. At 24 months after surgery, ABS in bypass plus colostomy group was 0.6±0.6, while that in bypass group was 2.5±1.0, with a significant difference between two groups (t=8.797, P<0.001). At 1 year after surgery, barium enema examination was performed in all the patients of both groups. The barium emptying time was (21.2±3.8) hours and (95.8±86.2) hours in bypass plus colostomy group and bypass group respectively. The former group was significantly better than the latter group (t=4.740, P<0.001). Conclusions: Laparoscopic SCBCAC is an effective and safe procedure for the treatment of senile slow transit constipation and can significantly improve prognosis. Its clinical efficacy is better than laparoscopic SCBAC.

Abstract
Objective: To investigate the prevalence of iron deficiency (ID) and iron deficiency anemia (IDA) in pregnant women in urban areas of China. Methods: The study was a national cross-sectional survey conducted from September 19th, 2016 to November 20th, 2016. According to the classification of the National Bureau of Statistics, all survey sites were set up in 6 regions of the country.Pregnant women were continuously selected using multistage stratified sampling. A total of 12 403 pregnant women were collected and examined for serum ferritin and hemoglobin levels. Results: The median serum ferritin level during pregnancy was 20.60 μg/L (11.78-36.98 μg/L) , the hemoglobin level was (118±12) g/L. With the progress of pregnancy, the levels of serum ferritin and hemoglobin decreased gradually. The median serum ferritin levels in the first, second trimester and third trimester were 54.30 μg/L (34.48-94.01 μg/L) , 28.60 μg/L (16.40-50.52 μg/L) , and 16.70 μg/L (10.20-27.00 μg/L) respectively (P<0.01) . The mean hemoglobin levels were (127±10) g/L, (119±11) g/L and (117±11) g/L respectively (P<0.01) . The prevalence of ID in urban pregnant women was 48.16% (5 973/12 403) , and IDA prevalence was 13.87% (1 720/12 403) . The prevalence of IDA in the first, second trimester and third trimester were 1.96% (20/1 019) , 8.40% (293/3 487) and 17.82% (1 407/7 897) ,respectively (P<0.01) . The prevalence of standardized ID and IDA were significantly different in various regions of China (P<0.01) . The standardized prevalence of ID were relatively higher in East China and Northeast China, 57.37% and 53.41% respectively, while it was the lowest in Southwest China, 30.51%. The standardized prevalence of IDA in South Central, Northwest, and East China were relatively high, 21.30%, 16.97% and 17.53% respectively, and the standardized prevalence of IDA in Southwest China was the lowest, 5.44%, the differents in various regions were significant (all P<0.01) . Conclusion: The current phenomenon of ID and IDA in pregnant women is still very common, and nutrition and health care during pregnancy should be strengthened.

Abstract
Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) which represented a new two-steps liver resection procedures has been considered a revolutionary innovation for liver surgery technique in recent 10 years, it was first discovered by Professor Lang in Germany in 2007.The first step of the classic surgical procedures for portal vein ligation and liver parenchyma, until the future liver remnant (FLR) increased to a sufficient remnant then resect the right three-leaf liver.With the development of ALPPS, the method of hepatic parenchyma separation and isolation materials have been modified, which improves the safety of operation.ALPPS can speed up the regeneration of FLR in short period of time and therefore accurate assessment of FLR and liver reserve function preoperatively, which also can effectively prevent postoperative liver failure.However, it still remains controversy due to the high incidences of mobility and mortality perioperatively, how to solve this problem and chose the indications is the key.In China, 80% of liver cancer patients are associated with liver cirrhosis which the potential of FLR regeneration is limited. Whether ALPPS is applicable to the liver cancer patients in China remains to be further investigated, looking forward to a large number report of cases to give a more objective assessment.

Abstract
miR-34a is significantly down-regulated in breast cancer tissues and cell lines, which may be correlated with breast cancer multi-drug resistance (MDR). Here, we conducted cell-based experiments and clinical studies in a cohort of 113 breast cancer samples to analyze miR-34a expression and breast cancer MDR. Expression of miR-34a is down-regulated in the multi-drug resistant MDR-MCF-7 cells compared with its parental cells. Patients with miR-34a low expression had poorer overall survival (OS) and disease free survival (DFS) in comparison with those with high expression. Transfecting miR-34a mimics into MDR-MCF-7 breast cancer cells led to partial MDR reversal. Compared with the control group, miR-34a significantly reduced both the mRNA and protein expressions of BCL-2, CCND1 and NOTCH1, but no obvious changes were found in P53 or TOP-2a expression. In breast cancer tissue samples, the expression of miR-34a was related to BCL-2, CCND1 and NOTCH1, but not to HER-2, P53 and TOP-2a. Altogether, our findings suggest that miR-34a is an MDR and prognosis indicator of breast cancer, which may participate in the regulation of drug-resistant breast cancer by targeting BCL-2, CCND1, and NOTCH1.

Abstract
Diabetic retinopathy (DR), an important complication of diabetes mellitus (DM), is not well understood. T helper cell balance (Th1/Th2) is involved in various autoimmune diseases; however, its role in DR is not understood. This study explores changes in Th1 and Th2 cytokine expression during DR. Blood samples were collected from 25 healthy volunteers (normal control group), 35 patients with type 2 DM (T2DM group) without DR, and 30 cases of T2DM patients with DR (DR group). Real-time PCR was used to measure mRNA expression of IL-2 and TNF-α, secreted from Th1 cells, and of IL-4 and IL-10, secreted from Th2 cells. We used ELISA to detect cytokine expression in serum to analyze the correlation between Th1 and Th2 cytokines. IL-2 and TNF-αmRNA and protein expression levels in the T2DM and DR groups were significantly higher than in the normal control group (P < 0.05). Compared with the T2DM group, the DR group had higher IL-2 and TNF-αlevels (P < 0.05). IL-4 and IL-10 levels were lower in the DR group compared with the normal and T2DM groups (P < 0.05), while T2DM showed no difference compared with the normal control (P > 0.05). IL-2 and TNF-αwere negatively correlated with IL-4 and IL-10 in the DR group, respectively. We found that Th1 cytokine secretion was higher and Th2 cytokines secretion was lower during DR, leading to a Th1/ Th2 imbalance, suggesting that Th1/Th2 imbalance is a side effect for DR occurrence and development.

Abstract
Porous MnCo2O4 hollow nanocages have been fabricated via a simple template method using carbon spheres as a template. The hydrophilic surface of carbon spheres can adsorb Mn(2+) and Co(2+) ions simultaneously to form Mn,Co-adsorbed carbon spheres. The calcination of Mn,Co-adsorbed carbon spheres can result in porous hollow nanocages of MnCo2O4. The MnCo2O4 hollow nanocages are built by nanoscale MnCo2O4 crystals. Because of the unique porous hollow nanostructures, the resulting MnCo2O4/KB cathode shows an efficient electrocatalytic performance in LiTFSI/TEGDME electrolyte-based Li-O2 batteries. The MnCo2O4 hollow nanocages as the cathode catalysts can deliver better performance during the discharge/charge processes and good cycle stability compared with that of the pure KB carbon. The preliminary results manifest that porous MnCo2O4 hollow nanocages are promising high-performance cathode catalysts for Li-O2 batteries. This template technique is a simple, general, low-cost and controllable method and can be extended to prepare other transition metal oxide hollow nanostructures.

Abstract
OBJECTIVE To explore the clinical characteristics of IgA nephropathy (IgAN) with severe chronic periodontitis and aggressive periodontitis. METHODS A total of 436 hospitalized patients who underwent renal needle biopsy in the department of nephrology of China-Japan Friendship Hospital from November 2013 to December 2014 were recruited in the study and blindly had periodontal examination. The patients were divided into IgAN group and non-IgAN group according to the renal pathology. The patients with IgAN were further categorized as non-periodontitis, chronic periodontitis and aggressive peridontitis group by Haas classification. The chronic periodontitis group was continually divided into mild, moderate and severe periodontitis group. The levels of interleukin (IL)-1β and IL-6 in gingival crevicular fluid were analyzed by enzyme-linked immunosorbent assays. RESULTS The prevalence of periodontitis in the study was 88.3% (385/436). The prevalence of chronic periodontitis and aggressive periodontitis were higher in patients with IgAN than those with non-IgAN (P<0.05). Degree of chronic periodontitis was correlated with pathologic grading of IgAN (r=0.48, P<0.001). Compared with IgAN patients with other types of periodontitis, those with severe chronic and aggressive periodontitis had more severe pathology, more frequent recurrent gross hematuria, higher levels of 24 h proteinuria, serum triglyceride and uric acid, higher periodontal probing depth and clinical attatchment level, as well as higer levels of IL-1β and IL-6, but had lower creatinine clearance rate (all P<0.05). CONCLUSIONS The prevalence of severe chronic and aggressive periodontitis was higher in patients with IgAN. Chronic periodontitis is correlated with the onset and development of IgAN. Patients with IgAN have worse condition with the aggravation of periodontitis.

Abstract
This study investigated the changes in peripheral benzodiazepine receptors (PBRs) in the penumbra after cerebral ischemia-reperfusion injury, and examined the effects of astragaloside IV (AST) on PBRs in rats. Sixty Sprague-Dawley rats were divided into a sham operation group, a model group, and three AST treatment groups. Cerebral ischemic models were induced by the clue-blocked method. Neurological deficits were examined. The animals were sacrificed after 2 h of ischemia and 24 h of reperfusion, and mitochondria from the penumbra were purified. PBR density (Bmax) and affinity were measured by radioligand assays. Mitochondrial [(3)H]PK11195 binding was correlated with neurological deficits in rats. Compared to the model group, the 10 mg/kg AST group, 40 mg/kg AST group, and 100 mg/kg AST group had fewer neurological deficits. The effects in the 40 mg/ kg group did not significantly differ from the effects in the 100 mg/ kg group. Compared to the model group, the 10 mg/kg AST group, 40 mg/kg group, and 100 mg/kg group had a decreased Bmax in the penumbra. The Bmax decreased in the 40 mg/kg AST group and in the 100 mg/kg AST group compared with the 10 mg/kg group. The Bmax and neurological deficits in the 40 mg/kg did not significantly differ from those in the 100 mg/kg group. By contrast, the AST-treated rats showed no significant changes in the binding parameter equilibrium dissociation constant compared with those in the sham operation group and the model group. AST protects ischemic brain tissue by inhibiting PBR expression after cerebral ischemia.

Abstract
AIM: To determine the clinicopathological characteristics of nonsteroidal anti-inflammatory drug (NSAID)-induced acute hepato-nephrotoxicity among Chinese patients.
METHODS: We conducted a retrospective chart review of patients using the International Classification of Diseases, Ninth Revision diagnosis code for acute kidney injury (AKI) (584.5 or 584.9) and for acute liver injury (ALI) (570.0 or 573.3) from January 2004 to December 2013. Medical records were reviewed to confirm the diagnosis of AKI and ALI and to quantify NSAID administration.
RESULTS: Seven of 59 patients (11.8%) were identified with acute hepato-nephrotoxicity induced by NSAIDs. Five patients (71.4%) received over the recommended NSAIDs dose. Compared with NSAIDs-associated mere AKI, the risk factors of NSAIDs-induced acute hepato-nephrotoxicity are age older than 60 years (57.1%), a high prevalence of alcohol use (71.4%) and positive hepatitis B virus (HBV) markers (85.7%). Compared with NSAIDs-associated mere ALI, the risk factors of NSAIDs-induced acute hepato-nephrotoxicity are age older than 60 years (57.1%), increased extracellular volume depletion (71.4%), and renin-angiotensin-aldosterone system (RAAS) inhibitor combined use (57.1%). Acute interstitial nephritis and acute tubulointerstitial disease were apparent in three out of six (42.9%) kidney biopsy patients, respectively. Acute hepatitis was found in four out of six (66.7%) liver biopsy patients. Overall complete recovery occurred in four patients within a mean of 118.25 ± 55.42 d.
CONCLUSION: The injury typically occurred after an overdose of NSAIDs. The risk factors include age older than 60 years, alcohol use, positive HBV markers, extracellular volume depletion and RAAS inhibitor combined use.

Abstract
The objective of this study was to introduce a method for repairing large soft-tissue defects on the foot. Distally based neuro-fasciocutaneous flaps with perforating vessels were designed along the saphenous and sural neurovascular axes. The cutaneous perforating branches of the major arteries of the lower extremities were used as pedicles, which provided a rotation arc for the cross-leg flap to cover the large-sized soft-tissue defects on the foot. We transferred 6 neurocutaneous vascular axial flaps, including 4 saphenous neurocutaneous axial flaps (ranging from 25 x 13 to 17 x 9 cm in area) with posterior tibial perforators as the pedicle, and 2 sural neurocutaneous axial flaps (ranging from 29 x 12 to 18 x 7 cm in area) supplied by the perforating branches of the peroneal vessels. These 6 cases of neuro-fasciocutaneous flaps survived with satisfactory cosmetic appearances and functional results on follow-up at 8 to 17 months post-surgery. Placing a distally based neuro-fasciocutaneous cross-leg flap with perforating vessels is an effective method for repairing large-sized soft-tissue defects on the foot.

Abstract
Single-crystalline undoped and phosphrous-doped (P-doped) p-type ZnTe nanowires (NWs) were synthesized via a simple vapor transport and deposition method. Both undoped and P-doped ZnTe nanowires have zinc blende structure and uniform geometry. X-ray diffraction peaks of the P-doped ZnTe nanowires show an obvious shift toward higher diffraction angle as compared with the undoped ZnTe nanowires. X-ray photoelectron spectroscopy confirms the existence of P-dopant in the ZnTe nanowires. Field-effect transistors based on both undoped and P-doped ZnTe nanowires were fabricated and characterized. Electrical measurements demonstrated that P-doping led to an enhancement in ptype conductivity of ZnTe nanowires. A defect reaction mechanism was proposed to explain the p-type behaviors of both undoped and P-doped ZnTe nanowires.

Abstract
Cell decay is an important part of microbiological endogenous processes, which consists of cell death (reduction in the amount of active bacteria) and activity decay (reduction in the specific activity of active bacteria). By means of measuring maximal anaerobic volatile fatty acid (VFA) uptake rates (VFAUR), analyzing 16S rRNA with fluorescence in-situ hybridization (FISH) and observing membrane integrity by live/dead staining, the aerobic decay characteristics of glycogen-accumulating organisms (GAOs) in an enriched GAOs sequencing batch reactor (SBR) system were investigated. It was experimentally identified that a highly enriched culture of GAOs (94%) was obtained by maintaining the temperature at 30 degrees C in the SBR and a high m (COD): m (P) at 100 in the feed. The experimental results and calculations revealed that the decay and death rates of GAOs were 0.132 d(-1) and 0.034 d(-1) respectively, which demonstrated that cell death and activity decay accounted for respective 26% and 74% of the total GAOs cell decay. For this reason, cell death was only a minor factor causing the cell decay of GAOs, and activity decay was mostly responsible for this process.

Abstract
Single-crystalline ZnTe nanowires were prepared by a simple vapor transport and deposition method. Photodetectors of individual ZnTe nanowires were fabricated to study photoconductivity of the nanowires. It was observed the nanowire photodetectors show the highest visible-light photoconductive gains among all reported photodetectors based on 1D nanostructure semiconductors, including CdS, CdSe, ZnSe, etc. The high photosensitivity and relatively fast response speed are attributable to the high crystal quality of the ZnTe nanowires. These results reveal that such single-crystalline ZnTe nanowires are excellent candidates for optoelectronic applications.

Abstract
The effect of transport stress on superoxide production and adenosine phosphate concentration in addition to avian uncoupling protein (avUCP), avian adenine nucleotide translocator, and avian peroxisome proliferator-activated receptor-gamma coactivator-1alpha mRNA levels of skeletal muscles in broilers was investigated. Arbor Acres chicks (n = 360, 46 d old, males) were randomly allotted to 1 of 5 treatments: unstressed control, 45-min (short-term) transport with 45-min (short-term) recovery, 45-min transport with 3-h (long-term) recovery, 3-h (long-term) transport with 45-min recovery, and 3-h transport with 3-h recovery. Each treatment consisted of 6 replicates with 12 birds each. All birds (except control group) were transported according to a designed protocol. Transport time affected reactive oxygen species production in the thigh muscle (P < 0.05), adenosine triphosphate (ATP) content and energy charge (EC) in both breast and thigh muscles (P < 0.05 for all 4 comparisons), ATP:adenosine diphosphate (ADP) ratio in the breast muscle (P < 0.05), and avUCP mRNA levels in the thigh muscle (P < 0.05). Long-term transport increased (P < 0.05) reactive oxygen species production, ATP content, ATP:ADP ratio, and EC in the thigh muscle, but it decreased ATP content, ATP:ADP ratio, and EC in the breast muscle. Long-term transport increased avUCP mRNA in the thigh muscle (P < 0.05). Long-term recovery increased the ATP (P < 0.05) and ADP (P < 0.05) concentrations, avian adenine nucleotide translocator mRNA (P < 0.05), and avian peroxisome proliferator-activated receptor-gamma coactivator-1alpha mRNA (P < 0.05) in the thigh muscle, whereas EC decreased (P < 0.05) in the breast muscle. There were interactions between transport and recovery time on ATP (P < 0.05), EC (P < 0.05), and avUCP mRNA level (P < 0.05) in the thigh muscle. This study suggests that long-term transport accelerates muscle energy metabolism and lipid peroxidation. A long-term recovery may help alleviate cellular damage and maintain meat quality by reducing the rate of energy metabolism and scavenging of free radicals formed.

Abstract
Coaxial nanocables with a single-crystalline zinc telluride (ZnTe) nanowire core and an amorphous silicon oxide (SiO(x)) shell have been synthesized via a simple one-step chemical vapor deposition (CVD) method on gold-decorated silicon substrates. The single-crystal ZnTe nanowire core is in zinc-blende structure along the [111] direction, while the uniform SiO(x) shell fully covers the core with no observable pin-hole or crack. Formation mechanisms of the ZnTe-SiO(x) nanocables are discussed. The ZnTe nanowire core shows p-type electrical properties while the SiO(x) shell acts as an effective insulating layer. The ZnTe-SiO(x) nanocables may have potential applications in nanoscale devices, such as p-type FETs and nanosensors.

Abstract
The characteristics of cell decay in biological wastewater treatment systems were investigated under aerobic condition, by measuring the decay rate and by determining the death rate with LIVE/DEAD dyeing experiments. It was found that cell decay in biological wastewater treatment systems can be actually described as two parts: decay caused by cell death and decay derived from activity decrease. The experimental results revealed that 60% of cell decay in a nitrifying system was caused by activity decrease and 40% was caused by cell death. In a heterotrophic system, however, activity decrease was responsible for 80% of cell decay, and the other cell decay for 20% was caused by cell death.

Abstract
Based on a BNR system--BCFS, the effect of COD/P and phosphate recovery on the BCFS process was experimentally investigated. The results indicate that a higher P-removal efficiency (87%) and a good P-effluent quality (< or = 0.8 mg x L(-1)) could be maintained at COD/P ratios higher than 24. When COD/P was reduced below 24, the P-removal efficiency was suddenly decreased down to 62% and the P-effluent went up to 5 mg x L(-1). Under the circumstance, chemical phosphate recovery in the side-stream of anaerobic supernatant was combined with bio-P removal. When the side-stream increased up to 30%, the P-effluent went back to < 1 mg x L(-1), with a corresponding phosphate recovery efficiency of 54%.

Abstract
Micro- and nanocubes of carbon have been synthesized by laser ablation in liquid. The morphology and structure analyses indicated that these micro- and nanocubes are single crystals with a body-centered cubic structure with a lattice constant of 5.46 angstroms, which is so-called C 8-like structure, and they have a slightly truncated shape bounded mainly by (200) facets. A blue-purple luminescence at room temperature was observed in the cathodoluminescence spectrum of the synthesized single micro- and nanocube of carbon, which exhibited that this unique carbon nanomaterial is a new semiconductor with blue luminescence. The physical and chemical mechanisms of the synthesis of carbon micro- and nanocubes were pursued upon laser ablation in liquid.

Abstract
AIM To observe the prevalence of hepatitis B virus (HBV) infection in maintenance hemodialysis patients. METHODS Eighty-eight hemodialysis patients who had been receiving hemodialysis regularly for an average of 39.45 +/- 7.57 (range from 36 to 49) mo were enrolled in this study. HBV markers were measured in these patients before hemodialysis and in 100 healthy controls by the chemiluminescent microparticle immunoassay (CMI) method in order to compare the incidence of HBV infection in hemodialysis patients versus normal healthy people. All patients were then divided into two groups: patients positive for HBV markers (i.e. those positive for HBsAg, anti-HBc, HBeAg, anti-HBe, with or without positive anti-HBs) (n = 33), and patients negative for HBV markers (including those only positive anti-HBs) (n = 55). The following information was obtained for all patients: socio-demographic data, number of blood transfusions and some laboratory investigations. After 39.45 +/- 7.57 mo follow-up, HBV markers were measured in these patients by CMI. RESULTS The incidence of HBV infection in maintenance hemodialysis patients was 37.5%, which was higher than in controls (9%). In the patients positive for HBV markers, there were 13 patients (39.4%) who had a history of blood transfusion, which was more than the number [12 (21.8%), P = 0.04] of patients negative for HBV markers. Eight of the 88 patients negative for HBV markers turned out to be positive, while three of the 33 patients positive for HBV markers turned out to be negative. There was no cirrhosis of the liver or hepatoma occurring in these patients. CONCLUSION Maintenance hemodialysis patients have a higher risk of HBV infection than the average population. The number of blood transfusions is associated with an increased prevalence of HBV. While it is hard for hemodialysis patients to eliminate HBV, the prognosis of patients with positive HBV markers is good.

Abstract
In this paper, investigations were undertaken to formulate the properties of fly ash-calcium sulfoaluminate (CSA) cement matrix by blending MSW fly ash with CSA cement. The compressive strength, pore structure, hydration phases, and leaching behavior of Zn and Pb doped MSW fly ash-CSA cement matrices were determined by XRD, MIP, DSC, FTIR, EDX, TCLP leaching test and other experiments. The results showed that the addition of MSW fly ash to form fly ash-CSA cement matrix reduced the compressive strengths of matrices and made the pore distribution of matrices coarser, compared to that of pure CSA cement matrix. However, fly ash-CSA cement matrix could effectively immobilize high concentration of heavy metal such as lead and zinc with much lesser leaching of TCLP. Besides ettringite AFt, Friedel phase was a new hydration phase formed in the matrix. The formation of these hydration phases was responsible for huge reservoir of heavy metal stabilization by chemical fixing. Therefore, it could be postulated that MSW fly ash-CSA cement matrix was a potential new constituent of S/S matrix for high concentration of heavy metals such as Zn and Pb ions.

Abstract
Long-term storag of engineered bio-artificial tissues is required to ensure the off-the-shelf availability to clinicians due to their long production cycle. Cryopreservation is likely the choice for long-term preservation. This study investigated the effects of dimethyl sulfoxide (DMSO) concentrations, cooling rates, cryoprotectant medium treatment methods and seeding on the cell viability of a tissue-engineered dermal substitute. The dermal fibroblast was cultured on a polyglycolic acid (PGA) scaffolding at 37degree C and a 5% CO<inf>2</inf>atmosphere for 14 days, and dermal slices (10×3×1.5mm) were used in the experimental group. The freezing was carried out in a computer-controlled programmable freezer at 0.5degree C/min, 1degree C/min and 2degree C/min in1.4M, 2.1M and 2.8M DMSO from 4degree C to -60degree C and then plunged into the liquid nitrogen tank immediately. After 24th of cryopreservation, the samples wereped in removed from liquid nitrogen and placed at room temperature in air for 0.5-1min, prior to submergence in a water bath at 37 degree C. viability of fresh control and cryopreserved dermal slices were determined with our modification of the MTT (3-[4,5-Dimethythiazol-2-yl] -2,5-diphenyltetrazolium bromide) assay. The effects of two cryoprotectant medium treatment methods and seeding (at -7degree C)on cell viability were also assessed. A cryopreservation protocol of 1degree C/min in 1.4M DMSO from 4degree C to -60degree C, and seeding at -7degree C proved optimal for this tissue-engineered dermal replacement, provided the dermal slice was transferred into the cryopreservation bag containing 1mL 1.4M DMSO bag and hold for 15min at 4degree C prior to freezing.

Abstract
In recent years, considerable impetus emerges to develop strategies for reducing excess sludge produced in biological wastewater treatment (BWT) systems. In this study, an experiment on sludge reduction by ultrasound treatment was conducted. The influences of sonication on observed yield, sludge reduction, effluent quality, sludge settleability and stability were extensively evaluated. It was found that ultrasound had an impressive potential to reduce sludge production. Moreover, it was also concluded that a treatment time of 10 minutes was more cost-effective for sludge reduction, and a reduction by 44% was reached with an ultrasonic intensity of 0.25 w/ml. The reduction could be mainly attributed to disintegration of bio-flocs and cryptic growth. In addition, sonication time seemed to be more effective to reduce sludge production compared with ultrasonic intensity. Slight deterioration of the effluent quality and some variations of the sludge settleability and stability were observed after ultrasound treatment.
