Abstract
Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R2 of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

Abstract
Anion exchange membranes (AEMs) are a crucial constituent for alkaline fuel cells. As the core component of fuel cells, the low performance AEMs restrict the development and application of the fuel cells. Herein, the trade-off between the OH- conductivity and dimensional stability was solved by constructing AEMs with adequate OH- conductivity and satisfactory alkali resistance using Tröger's base (TB) poly (crown ether)s (PCEs) as the main chain, the embedded quaternary ammonium (QA) and Na+-functionalized crown ether units as the cationic group. Crown ether is an electron donator, and can capture Na+ to form Na+-functionalized crown ether units to conveniently transfer OH- and significantly promote the alkaline stability of the AEMs. The influence of the Na+-functionalized crown ether units on the performance of AEMs was studied in detail. The PCEs based AEMs show an obvious hydrophobic-hydrophilic microphase separation. These features make them ideal platforms for the OH- conduction applications. As expected, the as-prepared PCEs-QA-100% (100% is the degree of cross-linking) AEM with an ionic exchange capacity (IEC) of 2.07 meq g-1 has a high OH- conductivity of 159 mS cm-1 at 80 °C. Furthermore, the membrane electrode assemblies fabricated using the PCEs-QA-100% AEM possess a maximum power density of 291 mW cm-2 under the current density of 500 mA cm-2.

Abstract
Eukaryotic cells can expand their coding ability by using their splicing machinery, spliceosome, to process precursor mRNA (pre-mRNA) into mature messenger RNA. The mega-macromolecular spliceosome contains multiple subcomplexes, referred to as small nuclear ribonucleoproteins (snRNPs). Among these, U1 snRNP and its central component, U1-70K, are crucial for splice site recognition during early spliceosome assembly. The human U1-70K has been linked to several types of human autoimmune and neurodegenerative diseases. However, its phylogenetic relationship has been seldom reported. To this end, we carried out a systemic analysis of 95 animal U1-70K genes and compare these proteins to their yeast and plant counterparts. Analysis of their gene and protein structures, expression patterns and splicing conservation suggest that animal U1-70Ks are conserved in their molecular function, and may play essential role in cancers and juvenile development. In particular, animal U1-70Ks display unique characteristics of single copy number and a splicing isoform with truncated C-terminal, suggesting the specific role of these U1-70Ks in animal kingdom. In summary, our results provide phylogenetic overview of U1-70K gene family in vertebrates. In silico analyses conducted in this work will act as a reference for future functional studies of this crucial U1 splicing factor in animal kingdom.

Abstract
Calonectria represents a genus of phytopathogenic ascomycetous fungi with a worldwide distribution. In recent years, there has been an increase in the number of taxonomic studies on these fungi. Currently, there are 169 described species of Calonectria based on comparisons of DNA sequence data, combined with morphological characteristics. However, for some of these species, the sequence data utilised at the time of their description were relatively limited. This has justified an urgent need to reconsider the species boundaries for Calonectria based on robust genus-wide phylogenetic analyses. In this study, we utilised 240 available isolates including the ex-types of 128 Calonectria species, and re-sequenced eight gene regions (act, cmdA, his3, ITS, LSU, rpb2, tef1 and tub2) for them. Sequences for 44 Calonectria species, for which cultures could not be obtained, were downloaded from GenBank. DNA sequence data of all the 169 Calonectria species were then used to determine their phylogenetic relationships. As a consequence, 51 species were reduced to synonymy, two new species were identified, and the name Ca. lauri was validated. This resulted in the acceptance of 120 clearly defined Calonectria spp. The overall data revealed that the genus includes 11 species complexes, distributed across the Prolate and Sphaero-Naviculate Groups known to divide Calonectria. The results also made it possible to develop a robust set of DNA barcodes for Calonectria spp. To accomplish this goal, we evaluated the outcomes of each of the eight candidate DNA barcodes for the genus, as well as for each of the 11 species complexes. No single gene region provided a clear identity for all Calonectria species. Sequences of the tef1 and tub2 genes were the most reliable markers; those for the cmdA, his3, rpb2 and act gene regions also provided a relatively effective resolution for Calonectria spp., while the ITS and LSU failed to produce useful barcodes for species discrimination. At the species complex level, results showed that the most informative barcodes were inconsistent, but that a combination of six candidate barcodes (tef1, tub2, cmdA, his3, rpb2 and act) provided stable and reliable resolution for all 11 species complexes. A six-gene combined phylogeny resolved all 120 Calonectria species, and revealed that tef1, tub2, cmdA, his3, rpb2 and act gene regions are effective DNA barcodes for Calonectria.

Abstract
Objective:To investigate the effect of vestibular rehabilitation exercise combined with manual reduction in the treatment of benign paroxysmal positional vertigo(BPPV). Method:A total of 186 patients with benign paroxysmal positional vertigo were selected and randomly divided into experimental group and control group . The control group was treated with manual reduction, while the experimental group was treated with manual reduction combined with vestibular rehabilitation exercises. Patients with posterior semicircular canal BPPV carried out Brandt-Daroff exercises, while patients with horizontal semicircular canal BPPV carried out Cawthorne-Cooksey exercises and position restriction. To analyze the clinical curative effect, DHI score, residual dizziness and recurrence of the two groups. Result:There was no significant difference in total efficiency rate and DHI score between the two groups at the first diagnosis(P>0.05). After 1 week, 2 weeks and 1 month of follow-up, the total efficiency rate of the experimental group were 90.3%, 91.4% and 93.5% respectively, which were significantly higher than those of the control group(P<0.05). Synchronously, the scores of DHI in experimental group were respectively 14.33±5.71, 12.25±4.98 and 9.45±3.70, which were significantly lower than the control group(P<0.05). For the experimental group, in the first diagnosis, 1 week, 2 weeks and 1 month after follow-up, residual dizziness patients were 29 cases, 13 cases, 8 cases and 0 cases. The mean duration of residual dizziness was (5.86±4.71) days, which was significantly lower than that in the control group(P<0.05). One month after follow-up, the recurrence of patients in the experimental group were 5 cases, while the control group were 11 cases, significant difference between the two groups(χ²=4.704, P=0.030). Conclusion:Manual reduction combined with vestibular rehabilitation exercise can significantly improve the therapeutic effect of BPPV, ameliorate the residual dizziness symptoms and reduce the recurrence rate, meanwhile improve the balance function and quality life of patients.

Abstract
Oral squamous cell carcinoma (OSCC) is still a leading cause of cancer death owing to distant metastasis, which is largely facilitated by tumor angiogenesis. MicroRNA (miR)-378a-5p and Kallikrein-related peptidase 4 (KLK4) participate in tumorigenesis and tumor metastasis according to previous studies, yet the exact role they play in tumor angiogenesis remains poorly understood. The aim of the present study is to investigate the effect of miR-378a-5p and KLK4 on angiogenesis of OSCC. MTT assay showed that the expression level of miR-378a-5p was negatively correlated with the proliferation of OSCC cells. ELISA and Western blot assay showed that down-regulation of miR-378a-5p promotes VEGF expression. Tube formation and in vivo chicken chorioallantoic membrane (CAM) assay showed that inhibition of miR-378a-5p reduced tube formation of human umbilical vein endothelial cells (HUVECs) and newly formed microvessel. On the contrary, over-expression of KLK4 enhanced angiogenesis of OSCC cells with increased VEGF expression, tube formation activity of HUVECs and newly formed microvessel. Moreover, the dual-luciferase assay validated that KLK4 was a target gene of miR-378a-5p. MiR-378a-5p silencing induced tube formation was suppressed by the downregulation of KLK4. Besides, the activation of Wnt/β-catenin signaling pathway in miR-378a-5p antagomir transfected cells was also blocked by the KLK4 shRNA. To sum up, our study suggests that miR-378a-5p suppressed angiogenesis of OSCC at least partly by the regulation of KLK4.

Abstract
Objective: To evaluate the feasibility and clinical value of suprapubic-assisted laparoendoscopic single-site surgery (SA-LESS) in nephroureterectomy using method of transvaginal natural orifice specimen extraction (NOSE) (SA-LESS+TV-NOSE NU). Methods: Four patients (three cases of renal pelvic carcinoma and one case of ureteral carcinoma) undergoing SA-LESS+TV-NOSE NU were enrolled between April 2015 and January 2016. After general anesthesia, the patients were placed in the lithotomy position with the affected side elevated by 60°. Two trocars were inserted at the medial margin of umbilicus, and the third one was inserted into abdominal cavity at the superior margin of pubic symphysis. The operation was performed under a direct vision with a 5.4 mm 0° flexible-tip laparoscope. Firstly, the distal ureter was isolated completely and blocked by a Hem-O-lok clip. Then, the laparoscopic nephrectomy was performed according to the standard method. Finally, the bladder cuff excision was executed and the incision was sutured. The intact specimen was placed inside a homemade bag and removed through the incision at posterior vaginal fornix. Results: All the procedures were successfully performed. The median operative time was 150 (range: 120 to 210) minutes, and the median estimated blood loss was 180 (range: 80 to 350) ml. No major perioperative complications occurred. The mean visual analogue score (VAS) of 24 hours and 48 hours after operation were 3.25 (range: 2 to 5) and 2.25 (range: 2 to 3). All the patients resumed ambulation on postoperative day 1. Pelvic drainage tube was removed on postoperative day 2-4. On postoperative day 7, urethral catheter was removed. The patients were discharged on postoperative day 7-9. During the follow-up of 20-29 months, the patient recovered well with no case of incisional hernia and pelvic, abdominal infections. The vaginal fornix incision healed well, and the umbilical and suprapubic puncture scars were not obvious. All the patients completed the patient-assessed acromegaly symptom questionnaire PASQ. The average PSAQ score of 3 months after surgery was 34.5. Three of them restarted their sex lives, with an average female sexual function index score of 16.0, which was not significantly different with that of preoperation (15.6). There was no tumor recurrence, metastasis and implantation in all cases. Conclusion: SA-LESS+TV-NOSE NU is safe and feasible for upper tract urothelial carcinoma with faster postoperative recovery, less pain, shorter hospitalization time, better cosmetic results, and does not cause negative effect on the female sexual function.

Abstract
BACKGROUND The molecular mechanisms involved in microRNAs (miRNAs) have been extensively investigated in gastric cancer (GC). However, how miR-331 regulates GC pathogenesis remains unknown.
AIM To illuminate the effect of miR-331 on cell metastasis and tumor growth in GC.
METHODS The qRT-PCR, CCK8, Transwell, cell adhesion, Western blot, luciferase reporter and xenograft tumor formation assays were applied to explore the regulatory mechanism of miR-331 in GC.
RESULTS Downregulation of miR-331 associated with poor prognosis was detected in GC. Functionally, miR-331 suppressed cell proliferation, metastasis and tumor growth in GC. Further, miR-331 was verified to directly target musashi1 (MSI1). In addition, miR-331 inversely regulated MSI1 expression in GC tissues. Furthermore, upregulation of MSI1 weakened the inhibitory effect of miR-331 in GC.
CONCLUSION miR-331 inhibited development of GC through targeting MSI1, which may be used as an indicator for the prediction and prognosis of GC.

Abstract
Objective:To investigate the expression and significance of CTHRC1 in patients with papillary thyroid cancinoma.Method:We collected 63 specimens of papillary thyroid carcinoma tissue with 36 specimens of the adjacent normal thyroid tissue and 23 specimens of thyroid nodular goiter. The expressions of CTHRC1 protein in these tissues were detected by immunohistochemical staining. The correlations between the expressions of CTHRC1 with clinicopathologic features,E-cadherin and Vimentin expression were analyzed.Result:CTHRC1 protein expression levels in papillary thyroid carcinoma tissue were significantly higher than those in adjacent normal thyroid tissue and benign disease(P<0.01);CTHRC1 expression was significantly correlated with lymph node metastases(P<0.05). Moreover,CTHRC1 expression was correlated with the expression of E-cadherin and Vimentin(P<0.01).Conclusion:CTHRC1 is related with the occurrence and miligant transformation of papillary thyroid cancinoma. We speculated that CTHRC1 might play a role in the epithelial-mesenchymal transition of papillary thyroid cancinoma.

Abstract
Objective: To analysis the treatment effect of the ulnar osteotomy and ring-shaped ligament reconstruction for the treatment of old Monteggia fracture in children by using Meta analyze, and the difference of clinical curative effect was compared in order to provide the basis for the selection of clinical treatment options for old Monteggia fractures in children. Methods: We searched databases such as CNKI, Wanfang database, Medline, PubMed, Embase and Science through computer, at the same time, the references of relevant documents were retrieved manually, and the data processing was carried out by the RevMan5.3 statistical software provided by the Cochrane cooperation network by incorporating the exclusion criteria. The results were obtained and analyzed. Results: A total of 17 standard literature, 438 cases, 224 cases of ulnar osteotomy, 214 cases with ring ligament repair and reconstruction were obtained. The operation scheme, which was mainly based on the lengthening of ulna osteotomy, was superior to the reconstruction of ring ligament reconstruction. The complications and second operation rates of the former was less than that of the latter. Conclusion: The surgical methods for the reconstruction of the ulna osteotomy and the ring-shaped ligament have advantages and disadvantages. The choice of the operative plan for the old Monteggia fracture should be based on the following factors: the time of the old Monteggia fracture formation, the degree of the ulnar and radial deformity and the familiarity of the operative method.

Abstract
Objective: To investigate the effect of intrauterine intervention on severe primary fetal hydrothorax. Methods: Twelve cases with severe fetal primary hydrothorax who underwent prenatal intervention from January 2014 to December 2017 in Guangdong Women and Children Hospital were retrospectively reviewed. Results: The median gestational age of prenatal diagnosis was 30.8 weeks (24.0-33.0 weeks) . All cases were excluded congenital chromosomal abnormalities by prenatal diagnosis, and had no complications of pregnancy during prenatal diagnosis and had hydrothorax. Three cases (3/12) were right hydrothorax, the other 9 cases (9/12) were bilateral. Thoracoamniotic shunting was performed in 7 cases (7/12) . Thoracentesis was performed in 5 cases (5/12) , and the hydrothorax reappeared soon after operation in 4 cases, shunt placement was performed again. The hydrothorax was dissolved in 2 cases, released in 6 cases.Tube falling off occurred in 1 case,treatment was abandoned in 1 case and intrauterine fetal death happened in 1 case, and 1 case wasn't rechecked by ultrasonic due to premature birth following thoracentesis. In 10 cases who had deliveries, 5 newborns (5/10) were premature, 6 newborns (6/10) underwent assisted mechanical ventilation, 8 newborns (8/10) underwent thoracic close drainage, all of them were discharged when hydrothorax resolved. Conclusions: Antenatal intervention may improve the chance of survival in severe primary fetal hydrothorax. Thoracoamniotic shunting is the first-choice for the primary severe fetal hydrothorax.

Abstract
Objective: To evaluate the efficacy of PVD chemo-regimen (Pegaspargase, vincristine and dexamethasone) combined with intensity-modulated radiotherapy (IMRT) for patients with early-stage extranodal nasal NK/T-cell lymphoma (ENKL). Methods: Clinical data of 52 patients with early-stage ENKL were collected during May 2010 and June 2015 in Department of Lymphoma, Cancer Hospital of Guizhou Medical University, and these patients firstly received a concurrent chemoradiotherapy of two-cycle of PVD and IMRT (gross tumor volume primary: 12.6-59.4 Gy) and then 2 to 4 cycles of PVD as subsequent chemotherapy, the efficacy and adverse responses were retrospectively analyzed and observed. Results: Follow-up stopped until December 2015, complete remission was seen in 44 cases (84.6%) and partial remission 7 cases (13.5%), out of 52 cases. A total of 1 case died of progression disease during treatment and within 1 year after treatment, 1 case died of pulmonary infection within 1 week after treatment, 2 cases survived with tumor; so the objective response rate and clinical benefit rate were both 98.1%, 1-year, 2-year and 3-year overall survival rates and progression free survival rates were all 93.6%, 1-year and 2-year disease free survival rates were both 90.3%; the correlation analysis showed that the radiotherapy dose was related to the curative effect (P<0.05). Short term adverse responses were observed in 6 cases (11.5%) with grade 3 leucocytopenia, in 5 cases (9.6%) with grade 3-4 dyslipidemia and in 2 cases (3.8%) with grade 3 hypoalbuminemia during chemoradiotherapy. All the patients had different degrees of radiation oral mucositis and radiation dermatitis. Conclusion: For early-stage ENKL, a concurrent chemoradiotherapy of PVD regimen and IMRT have a good therapeutic effect and adverse response can be tolerated.

Abstract
Objective: To investigate the application of hybrid technique for the treatment of cerebral arteriovenous malformations (CAVMs) and to assess the value of hybrid technique. Methods: The cases of CAVMs treated in Qilu hospital and People's Hospital of Xinjiang Uygur Autonomous Region from July 2011 to July 2016 were analyzed retrospectively.Two modes of hybrid surgery, "angiographic diagnosis-craniotomy lesion resection or/and hematoma clearance-intraoperative angiography evaluation" and "angiographic diagnosis-intraoperative embolization-craniotomy lesion resection or/and hematoma clearance-intraoperative angiography evaluation" were applied for all the cases.We placed an aneurysm clip as marker in surgery field during real-time angiography.If CAVMs residues occurred during surgery, we re-resected the residue according to the guidance of the marker (clip) and DSA imaging. Intra-operative angiography evaluated the results of CAVMs resection one more time.Postoperatively, follow-up CT scan was performed for all the patients. Results: Of all the cases with CAVMs, there were 8 cases of scale Ⅰ, 13 cases of scale Ⅱ, 10 cases of scale Ⅲ and 6 cases of scale Ⅳ according to Spetzler-Martin Scale.There were 28 cases of acute hemorrhagic CAVMs and 9 cases of chronic hemorrhagic CAVMs or no-hemorrhagic CAVMs.Intra-operative angiography showed CAVMs residues in 6 cases of acute hemorrhagic CAVMs and only one in chronic group.About 18.92% residual rate of CAVMs were found for the first time intra-operative assessment angiography.With the guidance of intra-operative angiography and aneurysm clip as Marker, all residues of CAVMs were resected totally.Follow up CT showed the hematomas disappeared in all the cases of acute hemorrhagic cases.The cure rate of CAVMs with hybrid surgery was 100% according to the final intra-operative assessment angiography. Conclusions: (1)Hybrid surgery for the treatment of CAVMs in one session could evaluate the results of CAVMs resection and instruct the surgical procedure according to real-time angiography.This model could improve the treatment safety and efficacy for patients with CAVMs.(2)Patients with higher Spetzler-Martin Scale (Ⅲ-Ⅳ) who need intra-operative embolization and patients with hemorrhagic CAVMs are more suitable for hybrid surgery.

Abstract
The aim of the study was to investigate the grass carp hemorrhagic infection pathway and its key-related genes. Grass carp reovirus (GCRV) might cause hemorrhagic disease in grass carps. Healthy grass carp fingerlings (N = 60) were divided into control and infected groups. Fish in the control group were intraperitoneally (ip) injected with 0.6% fish physiological saline; the infected group received 5,000,000 50% tissue culture infective doses of GCRV 873 standard strain, a double-stranded RNA (dsRNA) virus strain, ip, in 0.5 mL. Illumina HiSeqTM 2000 was used for transcriptome sequencing, and real-time polymerase chain reaction (PCR) used to detect complement factors II (C2), III (C3), and V (C5); profibrinolysin (PLG); and coagulation factor II (F2) expression. A total of 2,722,223 reads were detected in the control group, and 2,751,111 in the infected group. Among 11,023 unigenes obtained after transcriptome assembly, 10,021 unigenes were significantly differentially expressed. Gene ontology and KEGG analysis, a collection of databases dealing with genomes and biological pathways, were performed to classify unigenes into functional categories, to understand gene function and identify regulatory pathways. Real-time PCR analysis showed that C2, C3, C5, PLG, and F2 expression levels were down-regulated, confirming results of pathway-enrichment analysis. This is the first application of high-throughput sequencing technology to investigate the in vivo effects of GCRV, on genes and pathways involved in the immune response to infection in grass carp.

Abstract
By detecting expression of interleukin (IL)-17A, IL-10 and interferon-γ (IFN-γ) in serum of inflammatory bowel disease (IBD) patients, this study aims to analyze the effects of these factors on the pathogenesis of IBD. According to illness status, selected patients were divided into Crohns disease (CD) group (28 patients), ulcerative colitis (UC) group (74 patients) and normal control group (36 patients); enzymelinked immunosorbent assay (ELISA) was used to detect IL-17A, IL-10 and IFN-γ levels in serum; immunohistochemical assay was used to detect local IL-17A expression in the colonic mucosa of each group. Clinical results showed that IL-17A content of the UC group and CD group was significantly higher than that of the normal control group (p less than 0.05); IL-17A content of the CD group was higher than that of the UC group (p>0.05). The UC group had the highest IL-10 content, and the difference between the UC group and other two groups had statistical significance (p less than 0.05); the difference of IL-10 content between UC group and normal control group had no statistical significance (p>0.05). There was no significant difference of IFN-γ level between the CD group and the UC group and normal control group (p>0.05), and no significant difference of IFN-γ level was shown between the CD group and the UC group (p>0.05). Both the CD and UC groups showed IL-17A positive staining in cytoplasm of lymphocyte, however no positive staining was found in any layer of intestinal mucosa of the normal control group. IL-17A was locally expressed in the colon of IBD patients in remission; furthermore, it also had high expression in serum; thus, there still existed high expression of pro-inflammatory factor, which might be related to relapse of IBD. Therefore, prevention of IL-17A may become a feasible therapy for IBD in the future.

Abstract
Here, we characterized the structure and function of the coagulation factor II (FII) gene in grass carp and determined its role in coagulation mechanisms. The FII gene EST was obtained using a constructed splenic transcriptome database; the full-length FII gene sequence was obtained by 3' and 5' RACE. The open reading frame (ORF) of FII was cloned and the full-length gene was found to be 1718 bp, with an ORF of 1572 bp; the gene contained a 25 bp 5'-untranslated region (UTR) and 108 bp 3'-UTR. The ORF encoded 524 amino acids, including 74 alkaline amino acids (arginine and lysine) and 69 acidic amino acids (aspartic acid and glutamic acid). The theoretical pI was 6.22. The calculated instability index (II) was 39.81, indicating that FII was a stable protein; the half-life period was predicted to be approximately 30 h. Amino acid sequence comparisons indicated that grass carp FII showed most similarity (71%) to FII of Takifugu rubripes, followed by Oplegnathus fasciatus (48% similarity) and Larimichthys crocea (47% similarity). A real-time reverse transcription PCR analysis showed that under normal circumstances, FII was most highly expressed in the liver, followed by the gill, spleen, thymus, and head-kidney (P < 0.001). After injection of the grass carp reovirus 873 (GCRV873), the pattern of FII expression was significantly altered (P < 0.001); gene expression was high after injection, suggesting a response involving the initiation of the coagulation system and defense of the body in combination with the platelet and complement system.

Abstract
Accurate species identication is a crucial step in forensic entomology, as the insect collected on a corpse can provide useful information for estimation of postmortem interval (PMI). The utility of the forensically important Sarcophagidae (Diptera) for crime scene investigation has been severely restricted, as morphological identification is difficult, especially the identification of females and larvae. In this study, a method for using mitochondrial DNA (mtDNA) sequence data and phylogenetic analysis was performed to distinguish the three Chinese sarcophagid species: Boerttcherisca peregrina (Robineau-Desvoidy, 1830) Parasarcophaga albiceps (Meigen, 1826) and Parasarcophaga dux (Thompson, 1869) (Diptera: Sarcophagidae). DNA was extracted and analyzed by a 189 bp fragment of cytochrome coxidase subunit II (COII) gene. The monophyletic branches of the phylogenetic tree reveal that this marker is suitable for discrimination between these species, providing high support for separation on congeneric species. Therefore, the molecular method applied to the sarcophagid species identification is feasible.

Abstract
Many species of Muscidae are cosmopolitan synanthropic insects. It is frequently found on dead bodies after death, so an accurate identification of each species is necessary for the correct estimation of the postmortem interval (PMI). Identification species of Muscidae is traditionally performed through their morphological features. However, the morphological similarity of Muscidae in the level of species usually poses a challenge for forensic entomologists. Therefore a molecular method used 16S rRNA sequence on mitochondrial DNA was established for species identification. In this study, a 289 base pair region of mitochondrial DNA (mtDNA) coding for 16S rRNA was investigated for identification of the following forensically important species of Muscidae. The specimens were from four genera, including 18 Musca domestica (Linnaeus, 1758), 2 Ophyra spinigera (Stein, 1910), 2 Ophyra chalcogaster (Wiedemann, 1824), 1 Morellia hortorum (Fallén, 1817), and 1 Fannia canicularis (Linnaeus, 1761). 16S rDNA region allowed the identification of these species of Muscidae, indicating the possibility of separation congeneric species with molecular method.

Abstract
Five isolates of M. hapla originating from the Netherlands and California were inbred by sequential transfer of single egg masses to produce six strains. Cytological examination showed that oocytes of these strains underwent meiosis and had n = 16 chromosomes. Strains were tested for ability to infect and to develop on several hosts by in vitro assays. The two strains from California infected tomato roots at a higher rate than those from the Netherlands, but no difference among strains was seen for ability to develop on tomato with or without the resistance gene Mi-1. All strains developed on the common bean cultivar Kentucky Wonder, but strains differed in ability to develop on the nematode-resistant cultivar NemaSnap. Strain-specific differences were also seen in ability to infect and to develop on Solanum bulbocastanum clone SB-22. Strain VW13, derived from nematodes treated with the mutagen EMS, was defective in ability to infect tomato and potato roots in vitro. Comparison of DNA using AFLP markers showed an average of 4% of the bands were polymorphic across the six strains, but no correlation was observed between the geographical origin or virulence and DNA polymorphism pattern.

Abstract
Shoot tips of three apple genotypes, namely, Malus pumila cv. M26, Gala, and Hokkaido No. 9, were successfully cryopreserved using a modified encapsulation-dehydration method. As a result, in addition to a high survival rate and regeneration rate, the capacity of shoots regenerated from cryopreserved samples to root was enhanced. Eight M26 single-bud sibling lines were used to assess genetic stability. Although cytological examination revealed a ploidy difference in the noncryopreserved control, the ploidy constitution remained relatively stable during the period of cryopreservation. Amplified fragment length polymorphism (AFLP) assay was performed to detect DNA-level variation. No change in DNA fragment pattern and number was observed between the control and the cryopreserved samples. In addition, methylation-sensitive amplified polymorphism (MSAP) assay was carried out to investigate the DNA methylation status during the period of cryopreservation. It was found that cryopreservation induced a decrease in DNA methylation level.

Abstract
A new ion chromatographic method was developed for the quantitative determination of ammonia and potassium in tobacco. The tobacco samples were treated with dilute nitric acid and K+, NH4+ were extracted. The method is fast and convenient. The relationships between peak heights and initial concentrations of K+ and NH4+ were linear. The detection limits were 0.05 mg/L for K+ and 0.03 mg/L for NH4+. Recoveries of K+ and NH4+ were 96.7%-106.7% and 96.5%-109.1% respectively. The whole procedure of determination can be completed within 5 min.

Abstract
The development of nephrocalcinosis in rats fed a high phosphorus diet, and the effectiveness of the Chinese traditional medicine, Wulingsan, and its components (Poria, Alismatis Rhizoma, Atractylodis Rhizoma, Cinnamomi Ramus, Polyporus) in suppressing the development of calcinosis were studied. The rats were fed a high phosphorus diet (1.5% P) supplemented with Wulingsan or its individual components (0.5 g/kg body weight) as separate experimental groups for a 2-week period. Upon histological observation by light microscopy and electron microscopy, signs of nephrocalcinosis were observed in almost all areas of the kidney. Calculi, consisting mainly of needle-shaped crystals of hydroxyapatite, were observed in the proximal tubules, in the collecting ductal lumina, and in the mitochondria of the proximal tubular cells and the interstitial cells. X-ray microanalysis revealed that the calculi were composed of hydroxyapatite (Ca and P). In the group fed the diet supplemented with Wulingsan, the severity of calcinosis in the corticomedullary junction was only slight. In all groups fed individual components of Wulingsan, the severity of calcinosis was almost the same as that in the group fed the high phosphorus diet (1.5% P). Wulingsan suppressed the development of calcinosis in rats fed the high phosphorus diet supplemented with this Chinese medicine, whereas its individual components alone had no effect. The process of calcinosis and the mechanism responsible for the activity of this Chinese medicine in the suppression of calcinosis are discussed.

Abstract
TCR engagement of immature CD4(+)CD8(+) thymocytes induces clonal maturation (positive selection) as well as clonal deletion (negative selection) in the thymus. However, the cell death execution events of thymocytes during the negative selection process remain obscure. Using a cell-free system, we identified two different DNase activities in the cytosol of in vivo anti-TCR-stimulated murine thymocytes: one that induced chromosomal DNA fragmentation, which was inhibited by an inhibitor of caspase-activated DNase, and another that induced plasmid DNA degradation, which was not inhibited by an inhibitor of caspase-activated DNase. We purified the protein to homogeneity that induced plasmid DNA degradation from the cytosol of anti-CD3-stimulated thymocytes and found that it is identical with cyclophilin B (Cyp B), which was reported to locate in endoplasmic reticulum. Ab against Cyp B specifically inhibited the DNA degradation activity in the cytosol of anti-CD3-stimulated thymocytes. Furthermore, recombinant Cyp B induced DNA degradation of naked nuclei, but did not induce internucleosomal DNA fragmentation. Finally, we demonstrated that TCR engagement of a murine T cell line (EL4) with anti-CD3/CD28 resulted in the release of Cyp B from the microsome fraction to the cytosol/nuclear fraction. Our data strongly suggest that both active caspase-activated DNase and Cyp B may participate in the induction of chromosomal DNA degradation during cell death execution of TCR-stimulated thymocytes.

Abstract
AIM To investigate the possible role endothelin may play in the pathogenesis of varicocele and varicocele-induced infertility. METHODS In varicocele patients, radioimmunoassay is used to determine the blood endothelin concentration in the spermatic vein and the antecubital vein separately. RESULTS The blood endothelin concentration of the spermatic vein (66.8 +/- 23.5 pg/mL) was significantly higher (P < 0.05) than that of the antecubital vein (55.3 +/- 25.3 pg/mL). The endothelin concentration in the spermatic vein in Grade II varicocele patients was not significantly different from that in Grade III patients (P = 0.87). CONCLUSION The higher blood endothelin level in the spermatic vein may indicate the involvement of endothelin in the pathophysiology of varicocele and varicocele-induced infertility.

Abstract
The development of nephrocalcinosis and the time course of changes in kidney function, especially proximal tubular function, were studied in young male rats fed a high-phosphorus diet. The animals were fed a purified diet with a phosphorus content of either 0.5% (normal phosphorus diet) or 1.5% (high-phosphorus diet). In the group fed the high-phosphorus diet, nephrocalcinosis was found in 4 of 42 rats after 1 d of feeding and in all rats of this group at 3 d. The degree of nephrocalcinosis gradually increased with time. Upon histological observation by electron microscopy, vacuoles, lysosomes and swelling of microvilli in the proximal tubules were observed in rats fed the high-phosphorus diet after 1 d of feeding. Giant lysosomes with deposition of calcium and deposition of hydroxyapatite in mitochondria were observed in the proximal tubules of rats fed the high-phosphorus diet at 3 d. Albumin concentration in the urine of these rats was significantly increased at 3 d. The activity of N-acetyl-beta-D-glucosaminidase in the urine was also significantly increased after 1 d of feeding the high-phosphorus diet, and then reached a plateau. The beta 2-microglobulin concentration in the urine of rats fed the high-phosphorus diet was significantly increased at 14 d, and increased more toward 21 d. We concluded that nephrocalcinosis and injury to the proximal tubules are rapidly induced in rats fed a high-phosphorus diet.

Abstract
To determine the relationship between gastroesophageal reflux (GER) and pulmonary diseases, we studied 29 chronic bronchitis, 32 asthmatic patients, and 9 control subjects. GER was diagnosed by esophageal endoscopy and gastroesophageal scintiscanning. Evidence of GER in the chronic bronchitic patients was 51.74%; in the asthmatics it was 37.5%; and no GER was confirmed in the control subjects. Gastroesophageal scintiscan had 100% sensitivity, but only 68.42% specificity. The mechanism whereby reflux triggers pulmonary problems was investigated by using the scintiscan for pulmonary aspiration, but no pulmonary aspiration was detected in all subjects. Pulmonary function tests did not show any differences between patients with or without reflux (P > 0.05). Thus, our results show that GER is common in chronic bronchitics and asthmatics, which indicates that there is some relationship between GER and chronic bronchitis as well as asthma.

Abstract
A study was made in Neijiang City, Sichuan Province to observe the safety and immunogenicity of a live attenuated hepatitis A virus (HAV) vaccine (H2 strain). 3,031 children, aged 6 to 9 years, were injected subcutaneously with 10(6.0) TCID50, 10(5.5) TCID50, and 10(5.0) TCID50 of HAV vaccine; the seroconversion rate and antibody GMT were 97.52%-90.68%, GMT = 1:5.19 +/- 1.90-1:3.36 +/- 1.94; 84.75%-76.27%, GMT = 1:4.29 +/- 1.96-1:2.0 +/- 2.67; 53.23%-51.61%, GMT = 1:2.57 +/- 1.89-1:1.68 +/- 1.41 respectively after 4 weeks to 12 months of inoculation. Forty-eight children in the control group were anti-HAV negative at 4, 8, and 12 weeks; 21 children in the oral group were not antibody positive 4 and 8 weeks after oral administration of the vaccine. The stool specimens of 3 of the 14 vaccinated children were HAA positive. The results suggest that the live attenuated HAV vaccine (H2 strain) is of good immunogenicity and safety.

Abstract
High molecular weight DNA samples free of contaminating proteins and RNA obtained from one isolate (of Guangzhou origin) of Cysticercus tenuicollis and five isolates (of Tianjin, Harbin, Lanzhou, Shenyang and Zhengzhou origin) of Cysticercus cellulosae were subjected to thermal denaturation, restriction endonuclease digestion, Southern blotting and hybridization analysis. C. cellulosae DNA showed a melting temperature (Tm) of 82 degrees C corresponding to a 31% GC content whereas C. tenuicollis DNA melted at 85 degrees C suggesting 38.3% GC content. Visual inspection of ethidium bromide-stained gel showed differences not only between the DNAs of the two species of Taeniid cestodes, but also among the five isolates of C. cellulosae. Furthermore, we used two fragments (1.9kb and 5.5kb) of HindIII-derived restriction fragments of C. cellulosae DNA (Harbin origin) and pTS10 as probes to hybridize the DNAs of the Taeniid cestodes from six origins to detect inter- and intra-species genetic variation, the restriction fragment length polymorphisms (RFLPs) were identified.
