Abstract
The Barley stripe mosaic virus (BSMV) γb protein is a viral suppressor of RNA silencing (VSR) and symptom determinant. However, it is unclear how post-translational modification affects the different functions of γb. Here, we demonstrate that γb is phosphorylated at Ser-96 by a PKA-like kinase in vivo and in vitro. Mutant viruses containing a nonphosphorylatable substitution (BSMVS96A or BSMVS96R ) exhibited reduced viral accumulation in Nicotiana benthamiana due to transient induction of the cell death response that constrained the virus to necrotic areas. By contrast, a BSMVS96D mutant virus that mimics γb phosphorylation spread similarly to the wild-type virus. Furthermore, the S96A mutant had reduced local and systemic γb VSR activity due to having compromised its binding activity to 21-bp dsRNA. However, overexpression of other VSRs in trans or in cis failed to rescue the necrosis induced by BSMVS96A , demonstrating that suppression of cell death by γb phosphorylation is functionally distinct from its RNA silencing suppressor activities. These results provide new insights into the function of γb phosphorylation in regulating RNA silencing and the BSMV-induced host cell death response, and contribute to our understanding of how the virus optimizes the balance between viral replication and virus survival in the host plants during virus infection.

MOLECULAR PLANT PATHOLOGY 2018; 19:1222-1237.

Abstract
Barley stripe mosaic virus (BSMV) Triple Gene Block1 (TGB1) is a multifunctional movement protein with RNA-binding, ATPase and helicase activities which mainly localizes to the plasmodesmata (PD) in infected cells. Here, we show that TGB1 localizes to the nucleus and the nucleolus, as well as the cytoplasm, and that TGB1 nuclear-cytoplasmic trafficking is required for BSMV cell-to-cell movement. Prediction analyses and laser scanning confocal microscopy (LSCM) experiments verified that TGB1 possesses a nucleolar localization signal (NoLS) (amino acids 95-104) and a nuclear localization signal (NLS) (amino acids 227-238). NoLS mutations reduced BSMV cell-to-cell movement significantly, whereas NLS mutations almost completely abolished movement. Furthermore, neither the NoLS nor NLS mutant viruses could infect Nicotiana benthamiana systemically, although the NoLS mutant virus was able to establish systemic infections of barley. Protein interaction experiments demonstrated that TGB1 interacts directly with the glycine-arginine-rich (GAR) domain of the nucleolar protein fibrillarin (Fib2). Moreover, in BSMV-infected cells, Fib2 accumulation increased by about 60%-70% and co-localized with TGB1 in the plasmodesmata. In addition, BSMV cell-to-cell movement in fib2 knockdown transgenic plants was reduced to less than one-third of that of non-transgenic plants. Fib2 also co-localized with both TGB1 and BSMV RNA, which are the main components of the ribonucleoprotein (RNP) movement complex. Collectively, these results show that TGB1-Fib2 interactions play a direct role in cell-to-cell movement, and we propose that Fib2 is hijacked by BSMV TGB1 to form a BSMV RNP which functions in cell-to-cell movement.

Abstract
The purpose of this work is to investigate the total resection of bladder tumor under transurethral fluorescence cystoscopy. Nineteen patients with bladder tumor, from which we resected a total of 26 tumors, including 16 single tumors with diameters of 0.5~2 cm, were enrolled in the study. All tumors were located in the posterior wall or neck of the bladder. For the surgery, the size and location of tumors in the bladder were observed by fluorescence cystoscopy. Then, plasma electrocision was used to cut the full-thickness of the bladder to the fat outside of the bladder along the near-end of the tumor, then along the left and right side of bladder (to the far-end), and the full-thickness of the tumor was resected. Finally, the far-end tumor was removed and the full-thickness of the bladder at the bottom was completely resected. All operations were completed successfully within 10-40 min. There was little bleeding during surgery and no secondary bleeding after surgery. Tumor staging found 17 patients at T1 stage (20 tumors) and 2 patients at T2 stage (6 tumors). Patients were followed up for 6~12 months without any recurrence. We show here that total resection of bladder tumor can be accomplished under transurethral fluorescence cystoscopy and preventative resection can be conducted on the suspicious bladder wall with precision to eliminate tumor residue that promotes recurrence.

Abstract
Background How patients experience the symptoms/signs of psoriasis is highly relevant for assessing treatment response. Objectives Compare outcomes with guselkumab, placebo and adalimumab utilizing the novel, validated Psoriasis Symptoms and Signs Diary (PSSD). Methods VOYAGE 1 is an ongoing, phase III, double‐blinded, controlled trial of patients with moderate‐to‐severe psoriasis. Patients were randomized to guselkumab 100 mg every 8 weeks; placebo‐to‐guselkumab 100 mg every 8 weeks; or adalimumab 40 mg every 2 weeks. The PSSD was self‐administered to assess symptoms (i.e. itch, skin tightness, burning, stinging and pain) and signs (i.e. dryness, cracking, scaling, shedding/flaking, redness and bleeding) of psoriasis (0–10 [absent‐to‐worst‐imaginable]) every 24 h. Symptom and sign summary scores were derived (0–100) based on average scores of the individual symptoms and signs. Proportions of patients with clinically meaningful improvements and symptom‐ and sign‐free scores of 0 were evaluated across treatment groups at weeks 16, 24 and 48. Results At baseline, 652 of 837 randomized patients had PSSD scores. The proportion of patients achieving clinically meaningful improvements in PSSD summary scores was significantly higher in the guselkumab group compared with the placebo group at week 16 (P < 0.001) and compared with the adalimumab group at weeks 24 (P = 0.002) and 48 (P < 0.001). The proportions of patients achieving PSSD symptom and sign summary scores of 0 (i.e. symptom‐ and sign‐free) were significantly higher for guselkumab vs. placebo at week 16 and vs. adalimumab at weeks 24 and 48 (all P < 0.001). Conclusions Based on PSSD scores, greater improvements in symptoms and signs of psoriasis were reported by patients treated with guselkumab compared with placebo at week 16 or adalimumab through 48 weeks.

Abstract
PURPOSE To explore the effects and mechanisms of anti-tumor necrosis factor-α (TNF-α) antibody on insulin resistance (IR) in rats with sepsis-induced stress hyperglycemia. METHODS The sepsis-induced stress hyperglycemic rat model was constructed by cecal ligation and puncture combined with the intraperitoneal injection of lipopolysaccharide. The rats were randomly divided into six groups: normal control (NC) group, surgical rats (Cntl) group, high-dose anti-TNF-α antibody therapy (TNF, 6 mg/kg) group, low-dose anti-TNF-α antibody therapy (Tnf, 3 mg/kg) group, insulin therapy (INS) group, and INS + Tnf group. The blood glucose and serum insulin concentrations were detected, followed by analysis of intraperitoneal glucose tolerance test (IPGTT) and hyperinsulinemic-euglycemic clamp. Finally, the expression levels of phospho-Akt (p-Akt), Akt, p-mTOR, mTOR, nuclear factor-κB (NFκB), I kappa beta kinase (IKKβ), and suppressor of cytokine signaling (SOCS-3) were detected by western blotting. RESULTS There was no significant difference in blood glucose concentrations among these groups, while the serum insulin concentration in TNF and Tnf groups was lower than that in the Cntl group at postoperative 6 h (P < 0.05). IPGTT analysis revealed that blood glucose level was lower in the TNF group than that in the Cntl group (P < 0.05). The glucose infusion rate in the Cntl group was lower than that in the Tnf and TNF groups (P < 0.05). The p-Akt/Akt, p-mTOR/mTOR ratio, and expression levels of NFκB, IKKβ and SOCS-3 were lower in the drug intervention than that in the Cntl group (P < 0.05). CONCLUSIONS Anti-TNF-α antibody could reduce IR by inhibiting AKt/mTOR signaling pathway and the expression levels of NFκB, IKKβ, and SOCS-3 in rats with sepsis-induced stress hyperglycemia.

Abstract
OBJECTIVE To investigate the expression features of long non-coding RNA (lncRNA) DLEU7-AS1 in colorectal cancer (CRC), so as to further study its role in the occurrence and development of CRC and its potential regulatory mechanism. PATIENTS AND METHODS The expression levels of lncRNA DLEU7-AS1 in 82 pairs of CRC tissues and para-carcinoma normal tissues were detected via quantitative Real-time polymerase chain reaction (qRT-PCR), and the correlation of DLEU7-AS1 expression with pathological indexes of CRC and patients' prognosis was analyzed. Besides, the expression of DLEU7-AS1 in CRC cells was further detected via qRT-PCR. The DLEU7-AS1 knockdown expression model was established using small interfering RNA in CRC cell lines HT-29 and HCT-116, and the effect of DLEU7-AS1 on biological functions of CRC cells was analyzed via Cell Counting Kit-8 (CCK-8) and transwell invasion/migration assay. Finally, its potential mechanism was investigated via Western blotting. RESULTS The results of qRT-PCR showed that the expression level of DLEU7-AS1 in CRC was significantly higher than that in normal tissues, and the difference was statistically significant. Compared with those in patients with low DLEU7-AS1 expression, the tumor stage in patients with high DLEU7-AS1 expression was higher, the prevalence rates of lymph node metastasis and distant metastasis were higher, and the overall survival rate was lower. Compared with those in the negative control group, the cell proliferation, invasion, and migration capacities were decreased significantly in DLEU7-AS1 knockdown expression group. Moreover, the results of Western blotting revealed that the expressions of key proteins in Wnt/β-catenin pathway, including β-catenin, c-myc, and cyclinD1, were decreased in si-DLEU7-AS1. CONCLUSIONS The expression of DLEU7-AS1 is significantly increased in CRC, which is markedly associated with CRC staging, lymph node metastasis, distant metastasis and poor prognosis. DLEU7-AS1 may promote the proliferation, invasion and migration capacities of CRC through regulating the Wnt/β-catenin pathway.

Abstract
The intention of neoadjuvant chemotherapy in breast cancer is to shrink the tumors in locally advanced disease and to improve the degree of cure of operation (security). Therefore, it is expected to improve quality of life and survival for patients. Additionally, neoadjuvant chemotherapy is administered based on the observable primary tumor. Thus, the timely assessment of tumor response to chemotherapeutic drugs provides a basis for subsequent treatment. Currently, however, the treatment concept of breast cancer requires whole process management. It requires clinicians to develop the overall treatment strategy according to tumor biological information of patients, as well as timely and reasonable adjustment of the subsequent treatment based on the response to neoadjuvant chemotherapy. These are new problems arising from neoadjuvant chemotherapy.

Abstract
BACKGROUND Symmetrical acral keratoderma (SAK) is a rare skin disorder and its pathogenesis and inheritability are unknown. OBJECTIVES To investigate the inheritance and pathogenesis of SAK. METHODS Four SAK cases occurred in a four-generation Chinese family. Exome sequencing identified SNPs with potential SAK-related mutations, and a potentially responsible gene transcription factor 4 (TCF4) was identified. TCF4 was then sequenced in all 11 family members, and pedigree analysis was performed. Histopathology and immunohistochemistry evaluated TCF4 expression in skin lesions. The gene mutation was investigated in human keratinocytes for keratin-related protein expression. RESULTS A novel heterozygous missense mutation, c.85C>A (p.Pro29Thr) was found in TCF4. The mutation showed autosomal dominant inheritance and perfectly cosegregated with the SAK phenotype in all family members. In skin lesions, TCF4 was present in the cytoplasm and membranes of the basal layer, the stratum spinosum and the stratum granulosum of the epidermis. The mutant TCF4 induced overexpression of differentiation markers including KRT1, KRT14, loricrin and involucrin. CONCLUSIONS A SAK-related gene mutation in TCF4 may function through transcriptional regulation of keratin.

Abstract
Objcetive: To investigate the incidence and risk factors of Lymphocele infection and the optimal timing for drainage after pelvic lymphadenectomy. Methods: This retrospective study was carried out on 397 patients who received a pelvic lymphadenectomy with or without a para-aortic lymphadenectomy between January 2009 and April 2016, due to endometrial cancer in General hospital of Tianjin medical university.A total of 76 patients developed lymphocele and 20 patients developed lymphocele infection. Results: (1)The incidence of lymphocele infection was 5.04% (20/397). Single factor analysis indicated diameter of lymphocele ≥5 cm and postoperative anemia were associated with lymphocele formation (P<0.001, P=0.023). Multiple factors Logistic analysis through the adjustment of the factors showed diameter of lymphocele ≥5 cm was the independent risk factors for lymphocyst infection (P<0.001). (2)The total treatment period of cases treated only with antibiotics tended to be shorter than that of cases treated with combined antibiotics and drainage (P=0.008). However, for severe cases which needed drainage, initiating the drainage by day 3 significantly shortened the total treatment period compared with cases started on or after day 4 (P=0.048). Conclusion: To identify the risk factors of the lymphocele infection is useful to help reduce the incidence of them with effective measurement.When drainage is required in addition to antibiotics, the earlier the drainage is performed, the shorter the treatment period is.

Abstract
A novel magnetically recoverable, visible light active TiO2-WO3 composite (Fe3O4@SiO2@TiO2-WO3) was prepared to enable the photocatalyst recovery after the degradation of bisphenol A (BPA) under simulated solar light. For comparison, the photocatalytic activity of other materials such as non-magnetic TiO2-WO3, Fe3O4@SiO2@TiO2, TiO2, and the commercial TiO2 P25 was also evaluated under the studied experimental conditions. The structure and morphology of the synthesized materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HR-TEM), and electron dispersion spectroscopy (EDS). Moreover, Brunauer-Emmett-Teller (BET) surface area and magnetic properties of the samples were determined. The Fe3O4@SiO2@TiO2-WO3 and TiO2-WO3 led to a BPA degradation of 17.50 and 27.92 %, respectively, after 2 h of the simulated solar light irradiation. Even though their activity was lower than that of P25, which degraded completely BPA after 1 h, our catalysts were magnetically separable for their further reuse in the treatment. Furthermore, the influence of the water matrix in the photocatalytic activity of the samples was studied in municipal wastewater. Finally, the identification of reaction intermediates was performed and a possible BPA degradation pathway was proposed to provide a better understanding of the degradation process.

Abstract
RNA viruses encode various RNA binding proteins that function in many steps of viral infection cycles. These proteins function as RNA helicases, methyltransferases, RNA-dependent RNA polymerases, RNA silencing suppressors, RNA chaperones, movement proteins, and so on. Although many of the proteins bind the viral RNA genome during different stages of infection, our knowledge about the coordination of their functions is limited. In this study, we describe a novel role for the Barley stripe mosaic virus (BSMV) γb as an enhancer of αa RNA helicase activity, and we show that the γb protein is recruited by the αa viral replication protein to chloroplast membrane sites of BSMV replication. Mutagenesis or deletion of γb from BSMV resulted in reduced positive strand (+) RNAα accumulation, but γb mutations abolishing viral suppressor of RNA silencing (VSR) activity did not completely eliminate genomic RNA replication. In addition, cis- or trans-expression of the Tomato bushy stunt virus p19 VSR protein failed to complement the γb replication functions, indicating that the direct involvement of γb in BSMV RNA replication is independent of VSR functions. These data support a model whereby two BSMV-encoded RNA-binding proteins act coordinately to regulate viral genome replication and provide new insights into strategies whereby double-stranded viral RNA unwinding is regulated, as well as formation of viral replication complexes.

Abstract
UNLABELLED Endocan is a novel marker for inflammation but its significance in preeclampsia remains unknown. OBJECTIVE The aims of this study were to delineate the changes of maternal endocan in normal pregnancy and preeclampsia and to explore its possible role in the pathogenesis of preeclampsia. MATERIALS AND METHODS Blood samples were taken from 42 non-pregnant women, from 43 normal pregnant women at third trimester, and from 41 preeclamptic women. Serum endocan levels were determined with enzyme-linked immunosorbent assay (ELISA) and compared among the groups. RESULTS There were no significant differences in serum endocan among non-pregnant women, normal pregnant women, and women with preeclampsia (X²= 2.207, p = 0.137) and there was no significant difference in serum endocan between women with mild and severe preeclampsia (Z= 0.368, p = 0. 713). The authors concluded that serum endocan did not change in pregnancy and preeclampsia, indicating endocan may not be involved in the pathogenesis of preeclampsia.

Abstract
OBJECTIVE To observe the success rate of telbivudine (LdT) for the prevention of perinatal transmission of hepatitis B virus (HBV) and the incidence of alanine aminotransferase (ALT) elevation during LdT treatment and after LdT withdrawal in HBV-infected pregnant woman with high viremia in immune-tolerant phase and receiving LdT treatment at the end of pregnancy, and to evaluate the efficacy of LdT in the prevention of perinatal transmission and the safety for pregnant women. METHODS Pregnant women infected with HBV in immune-tolerant phase who had normal ALT levels (≤40 U/L) and high viremia (HBV DNA ≥6 log10 IU/ml) with positive HBeAg were enrolled as subjects. All pregnant women received antiviral treatment with LdT at the end of pregnancy to prevent perinatal transmission of HBV. All infants received standard combined immunoprophylaxis. Failure for prevention of perinatal transmission of HBV was defined as positive HBsAg or HBV DNA in infants 7 months of age (or at one month after the third injection of hepatitis B vaccine). Liver function, HBV DNA, and HBV serological markers were evaluated at baseline, after 1 month of treatment, before childbirth, and 1, 3, and 6 months after drug withdrawal. SPSS 16.0 software was used to analyze the data. Between-group comparison of continuous data was made by t test, and comparison of categorical data was made by chi-square test. RESULTS One hundred and four pregnant women (treatment group) received oral administration of 600 mg LdT once a day, and 25 pregnant women (observation group) did not receive any antiviral therapy. The success rate for the prevention of perinatal transmission was significantly higher in the treatment group than in the observation group (100% vs 89.47%, χ (2) = 9.862, P = 0.028). There was no significant difference in the incidence of ALT elevation during treatment and within 6 months after drug withdrawal between the treatment group and the observation group (4.81% (5/104) vs 4.00% (1/25), χ (2) = 0.030, P = 1.000). In the treatment group, the mean HBV DNA at baseline was significantly higher than that before childbirth (8.20±0.78 vs 3.98±0.90 log10IU/ml, t = 6.979, P < 0.001). One hundred patients with drug withdrawal had HBV DNA increased to 8.11±0.80 log10 IU/ml at one month after childbirth. CONCLUSION LdT treatment at the end of pregnancy can effectively reduce the incidence of perinatal transmission of HBV in pregnant women with high viremia in immune-tolerant phase. The immediate drug withdrawal after childbirth is safe for the mother. The incidence of hepatitis is low after drug withdrawal.

Abstract
BACKGROUND Brassica yellows virus (BrYV), proposed to be a new polerovirus species, three distinct genotypes (BrYV-A, BrYV-B and BrYV-C) have been described. This study was to develop a simple, rapid, sensitive, cost-effective method for simultaneous detection and differentiation of three genotypes of BrYV. RESULTS In this study, a multiplex reverse transcription-polymerase chain reaction (mRT-PCR) was developed for simultaneous detection and differentiation of the three genotypes of BrYV. The three genotypes of BrYV and Tunip yellows virus (TuYV) could be differentiated simultaneously using six optimized specific oligonucleotide primers, including one universal primer for detecting BrYV, three BrYV genotype-specific primers, and a pair of primers for specific detection of TuYV. Primers were designed from conserved regions of each virus and their specificity was confirmed by sequencing PCR products. The mRT-PCR products were 278 bp for BrYV-A, 674 bp for BrYV-B, 505 bp for BrYV-C, and 205 bp for TuYV. Amplification of three target genotypes was optimized by increasing the PCR annealing temperatures to 62 °C. One to three fragments specific for the virus genotypes were simultaneously amplified from infected samples and identified by their specific molecular sizes in agarose gel electrophoresis. No specific products could be amplified from cDNAs of other viruses which could infect crucifer crops. Detection limits of the plasmids for multiplex PCR were 100 fg for BrYV-A and BrYV-B, 10 pg for BrYV-C, and 1 pg for TuYV, respectively. The mRT-PCR was applied successfully for detection of three BrYV genotypes from field samples collected in China. CONCLUSIONS The simple, rapid, sensitive, and cost-effective mRT-PCR was developed successfully for detection and differentiation of the three genotypes of BrYV.

Abstract
Co-infection of none-coding satellite RNAs (sat-RNAs) usually inhibits replication and attenuates disease symptoms of helper viruses. However, we find that the sat-RNA of Beet black scorch virus (BBSV) and low temperature (18°C) additively enhance the systemic infection of BBSV in Nicotiana benthamiana. Northern blotting hybridization revealed a relatively reduced accumulation of BBSV-derived small interfering RNAs (siRNAs) in presence of sat-RNA as compared to that of BBSV alone. Cloning and sequencing of total small RNAs showed that more than 50% of the total small RNAs sequenced from BBSV-infected plants were BBSV-siRNAs, whereas the abundance of sat-siRNAs were higher than BBSV-siRNAs in the sat-RNA co-infected plants, indicating that the sat-RNA occupies most of the silencing components and possibly relieves the RNA silencing-mediated defense against BBSV. Interestingly, the 5' termini of siRNAs derived from BBSV and sat-RNA were dominated by Uridines (U) and Adenines (A), respectively. Besides, the infection of BBSV alone and with sat-RNA induce down-regulation of miR168 and miR403, respectively, which leads to high accumulation of their targets, Argonaute 1 (AGO1) and AGO2. Our work reveals the profiles of siRNAs of BBSV and sat-RNA and provides an additional clue to investigate the complicated interaction between the helper virus and sat-RNA.

Abstract
OBJECTIVE Cerebral ischemia-reperfusion is the major pathophysiological process in stroke and can cause severe and lasting sequel. However, an intensive exercise training can potentially effect a quick and efficient recovery. We used swimming training on rats with cerebral ischemia-reperfusion (CIR) and explore the underlying neuroprotective mechanism(s), including the effects of intensive training on the expression of semaphorin 3A (Sema3A) and its receptor Neuropilin-1 (NRP-1). MATERIALS AND METHODS The middle cerebral artery occlusion/reperfusion (MCAO/R) model was established by inserting a thread into the middle cerebral artery of Sprague-Dawley (SD) rats, and randomly dividing into the control group and training groups for different training intensities. The control group and the sham group received no training. All the rats in various groups were further randomly divided into three sub-groups for different postoperative time points (3, 7, and 14 days after operation). The apoptosis and the expression of Sema3A and NRP-1 were analyzed using immunohistochemistry (IHC), RT-PCR, and Western blotting methods respectively. RESULTS The intensive training resulted in significant neurological function improvements at all the time points after MCAO, compared to that in the control group (p<0.05), with training group 3 (highest training intensity) showing the most remarkable recovery. The Sema3A and NP-1 expressions were significantly lower than those of the control group at all the time points (p<0.05), with training group 3 having the lowest levels (best recovery). CONCLUSIONS Intensive training can reduce cerebral damage after ischemia and reperfusion in rats, inhibit the MCAO-induced Sema3A and NRP-1 expression, and accelerate the restoring process of motor nerve functions.

Abstract
Controversy exists on the relationship between serum thyrotropin (TSH) and blood pressure, and only a few prospective studies are available up to now. The study aimed to investigate the association between serum TSH within the reference range and blood pressure through a 5-year follow-up study. A total of 623 subjects with normal TSH were followed up for 5 years, including the measurement of demographic data, blood pressure, height, weight and serum TSH. Finally, 531 subjects were included in this prospective study. Body mass index (BMI), prevalence of hypertension, and systolic and diastolic blood pressure were all higher at follow-up than at baseline. Adjusted for age, gender, smoking status, BMI and homoeostasis model assessment of insulin resistance (HOMA-IR) at baseline, multiple linear regression analyses found no relationship between serum TSH at baseline and levels of blood pressure at follow-up, but the changes in serum TSH levels during follow-up was positively associated with the changes in systolic blood pressure (B=2.134, P<0.05), which became more significant in women but not significant in men. The change of systolic blood pressure in group of TSH increase >0.5 mIU l-1 was significantly higher than in group of TSH decrease >0.5 mIU l-1 within reference, after adjusting for age, gender, smoking status, BMI and HOMA-IR at baseline. This result became more significant in women, but no statistical significance was observed in men. Co-variation with serum TSH levels and blood pressure was observed during 5-year follow-up among people with normal TSH.

Abstract
OBJECTIVE To compare the clinical efficacy of different treatments based on radical surgery in stage Ⅰ b2 and Ⅱ a2 cervical cancer through prospective randomized controlled study. METHODS A total of 133 patients with stage Ⅰ b2 and Ⅱ a2 cervical cancer treated at Beijing Obstetrics and Gynecology Hospital of Capital Medical University during January 2009 to December 2012 were enrolled and randomly assigned to receive one of the following three treatments: preoperative intracavitary irradiation(PII)group, radical hysterectomy(RH)group, and neoadjuvant chemotherapy(NACT)group. Operation method included uterine extensive resection, pelvic lymph node excision, with or without para-aortic lymph node resection. The recent curative effect and side effect of preoperative treatment were observed. The operation time, intraoperative blood loss, surgical complications, postoperative pathological risk factors and postoperative adjuvant therapy and side effect, the survival situation were evaluated among the 3 groups. RESULTS (1)The response rates were 88%(37/42)and 82%(37/45)respectively of the PII group and NACT group. The difference was insignificant(P=0.528). Side effects were less in the PII group. Only 5 patients(12% , 5/42)had slight gastrointestinal reaction. Myelosuppression and gastrointestinal reaction in NACT group were 76%(34/45)and 67%(30/45)respectively, which were more serious than that in group PII group(P<0.05).(2)Intraoperative blood loss and operation time in PII group [(678± 239)ml and(181±39)minutes]and NACT group [(625±137)ml and(168±25)minutes]had a decreasing trend compared with that in RH group [(711 ± 319)ml and(202 ± 64)minutes], but the differences were no significant(P >0.05). NACT group could shorten operation time compared with the RH group(P <0.05). The lymph node metastases rate were 30%(14/46), 29%(12/42)and 29%(13/45)and the deep stromal invasion rate were 22%(10/46), 31%(13/42)and 31%(14/45)in RH group, PII group and NACT group respectively(all P>0.05). The lymph-vascular space involvement(LVSI)in NACT group was significantly lower than that in RH group [31%(14/45)vs 57%(26/46), P=0.015]. The number of patients with histological risk factors in NACT group was higher thanthat in RH group [27%(12/45)vs 9%(4/46), P= 0.024]. All surgery were successfully completed and no treatment-related deaths occurred in three groups. The incidence of 3-4 grade adverse reactions evaluated by the common terminology criteria for adverse event(CTCAE)was 13%(6/46), 14%(6/42), 18%(8/45)in RH group, PII group and NACT group respectively(P=0.855). Three-year disease free survival(PFS)were 74.0%, 78.5% and 80.0%, and 3-year overall survival(OS)were 80.4%, 83.3% and 84.4% in RH group, PII group and NACT group respectively(all P>0.05). CONCLUSIONS The recent curative effect of PII and NACT were similar. They couldn't improve 3-year of PFS and OS of the patients with Ⅰb2 and Ⅱa2 stage cervical cancer. But NACT can reduce the operation difficulty and can reduce the incidence of postoperative pathological risk factors, which could reduce postoperative adjuvant therapy.

Abstract
Spot blotch disease resistance gene Sb3 was mapped to a 0.15 centimorgan (cM) genetic interval spanning a 602 kb physical genomic region on chromosome 3BS. Wheat spot blotch disease, caused by B. sorokiniana, is a devastating disease that can cause severe yield losses. Although inoculum levels can be reduced by planting disease-free seed, treatment of plants with fungicides and crop rotation, genetic resistance is likely to be a robust, economical and environmentally friendly tool in the control of spot blotch. The winter wheat line 621-7-1 confers immune resistance against B. sorokiniana. Genetic analysis indicates that the spot blotch resistance of 621-7-1 is controlled by a single dominant gene, provisionally designated Sb3. Bulked segregant analysis (BSA) and simple sequence repeat (SSR) mapping showed that Sb3 is located on chromosome arm 3BS linked with markers Xbarc133 and Xbarc147. Seven and twelve new polymorphic markers were developed from the Chinese Spring 3BS shotgun survey sequence contigs and 3BS reference sequences, respectively. Finally, Sb3 was mapped in a 0.15 cM genetic interval spanning a 602 kb physical genomic region of Chinese Spring chromosome 3BS. The genetic and physical maps of Sb3 provide a framework for map-based cloning and marker-assisted selection (MAS) of the spot blotch resistance.

Influence of non-thermal TiCl4/Ar+O2 plasma-assisted TiOx based coatings on the surface of polypropylene (PP) films for the tailoring of surface properties and cytocompatibility. MATERIALS SCIENCE & ENGINEERING. C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2016; 62:908-18.

Abstract
The superior bulk properties (corrosion resistance, high strength to weight ratio, relatively low cost and easy processing) of hydrocarbon based polymers such as polypropylene (PP) have contributed significantly to the development of new biomedical applications such as artificial organs and cell scaffolds. However, low cell affinity is one of the main draw backs for PP due to its poor surface properties. In tissue engineering, physico-chemical surface properties such as hydrophilicity, polar functional groups, surface charge and morphology play a crucial role to enrich the cell proliferation and adhesion. In this present investigation TiOx based biocompatible coatings were developed on the surface of PP films via DC excited glow discharge plasma, using TiCl4/Ar+O2 gas mixture as a precursor. Various TiOx-based coatings are deposited on the surface of PP films as a function of discharge power. The changes in hydrophilicity of the TiOx/PP film surfaces were studied using contact angle analysis and surface energy calculations by Fowke's approximation. X-ray photo-electron spectroscopy (XPS) was used to investigate the surface chemical composition of TiOx/PP films. The surface morphology of the obtained TiOx/PP films was investigated by scanning electron and transmission electron microscopy (SEM &TEM). Moreover, the surface topography of the material was analyzed by atomic force microscopy (AFM). The cytocompatibility of the TiOx/PP films was investigated via in vitro analysis (cell viability, adhesion and cytotoxicity) using NIH3T3 (mouse embryonic fibroblast) cells. Furthermore the antibacterial activities of TiOx/PP films were also evaluated against two distinct bacterial models namely Gram positive Staphylococcus aureus (S.aureus) and Gram negative Escherichia coli DH5α. (E.coli) bacteria. XPS results clearly indicate the successful incorporation of TiOx and oxygen containing polar functional groups on the surface of plasma treated PP films. Moreover the surface of modified PP films exhibited nano structured morphology, as confirmed by SEM, TEM and AFM. The physico-chemical changes have improved the hydrophilicity of the PP films. The in-vitro analysis clearly confirms that the TiOx coated PP films performs as good as the standard tissue culture plates and also are unlikely to impact the bacterial cell viability.

Abstract
OBJECTIVE To compare the different expressions of CD27, CD28, IL-17A, IFN-γ and TNF-α in the peripheral blood sampled from patients with colorectal carcinoma and healthy volunteers. PATIENTS AND METHODS Vδ2 T cells were isolated from the peripheral blood mononuclear cells (PBMCs) of patients with the colorectal carcinoma (CRC, n = 30) and healthy controls (HC, n = 21). The proportion of CD27, CD28, IL-17A, IFN-γ and TNF-α of Vδ2 T cells was detected by the flow cytometry. RESULTS We found that the proportion of IL-17A of Vδ2 T cells in PBMCs was higher in the CRC vs. the HC group (p < 0.05). A significant positive correlation was observed between the expression of IFN-γ and TNF-α of Vδ2 T cells. In the CRC patients, the proportions of IL-17A of CD27- Vδ2 T cells and CD28+ Vδ2 T cells were higher than those of CD27+ Vδ2 T cells and CD28- Vδ2 T cells, whereas the expression of IFN-γ and TNF-α of CD27-Vδ2 T cells was lower than that of CD27+ Vδ2 T cells. CONCLUSIONS Vδ2 T cells from PBMCs had higher expression of IL-17A in CRC patients than that in the HC group. The expression of IFN-γ and TNF-α of Vδ2 T cells from PBMCs was positively correlated. The cytokine profiles of peripheral Vδ2 T cells were likely determined by a CD27 and CD28 involving mechanism.

Step-down vs. step-up noxious stimulation: differential effects on pain perception and patterns of brain activation. Acta Anaesthesiol Scand 2016; 60:117-27. [PMID: 26355384 DOI: 10.1111/aas.12607] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2015] [Revised: 07/13/2015] [Accepted: 07/29/2015] [Indexed: 01/12/2023]
Abstract
BACKGROUND We hypothesize that pain and brain responses are affected by changes in the presentation sequence of noxious stimuli that are, overall, identical in intensity and duration. METHODS During functional magnetic resonance imaging (fMRI) scanning, 21 participants experienced three patterns of noxious stimulation: Up-type (step-up noxious stimulation, 15 s), Down-type (step-down noxious stimulation, 15 s), and Down-up-type (decreasing and increasing pattern of noxious stimulation, 15 s). The total intensity and duration of the three noxious stimulation patterns were identical, but the stimulation sequences were different. RESULTS Pain and unpleasantness ratings in the Down- and Down-up-type noxious stimulations were lower than in the Up-type noxious stimulation. The left prefrontal cortex [(PFC, BA (Brodmann area) 10, (-45, 50, 1)] was more highly activated in the Down- and Down-up-type noxious stimulations than in the Up-type noxious stimulation. The S1, S2, insula, bilateral PFC (BA 46), and midcingulate cortex were more highly activated in the Up-type noxious stimulation than in the Down-type noxious stimulation. PFC BA 10 was located at an inferior level compared to the bilateral PFC BA 46 (Z axis = 1 for BA 10, compared to 22 and 25 for the right and left BA 46, respectively). When cortisol level was increased, the left hippocampal cortex, along with the left parahippocampal cortex, was greatly activated for the Up-type noxious stimulation. CONCLUSION When pain cannot be avoided in clinical practice, noxious stimuli should be applied to patients in a step-down pattern that delivers the most intense pain first and the least intense pain last.
