Abstract
Background It was reported that epidural volume extension could decrease the ED50 of intrathecal plain bupivacaine. In this study, we investigated the ED50 of intrathecal hyperbaric ropivacaine followed by epidural normal saline bolus for cesarean section. Methods Sixty parturients were allocated into two groups in this prospective study. About 10 mL of epidural normal saline was given after the intrathecal dose of hyperbaric ropivacaine in the Group S (normal saline group), and no epidural injection of normal saline was given after the intrathecal ropivacainve injection in the Group C (control group). The dose of intrathecal ropivacaine for each parturient was decided by up-down allocation method. The initial dose was set as 10 mg. Effective anesthesia was defined as the level of T6 or above achieved within 10 minutes after intrathecal injection and no additional epidural drug to complete operation. The Massey formula was applied to calculate the ED50 of intrathecal ropivacaine. Results The ED50 of intrathecal ropivacaine for cesarean section determined by up-and-down method was 7.51 mg (95% CI, 7.09–7.93 mg) in the Group S and 8.29 mg (95% CI, 7.73–8.85 mg) in the Group C, and there was a significant difference in ED50 of ropivacaine between the two groups (P<0.05). Compared with the Group C, the ED50 of intrathecal ropivacaine decreased when followed by epidural normal saline bolus. Conclusion The ED50 of intrathecal hyperbaric ropivacaine for cesarean section is 8.29 mg, and it is reduced when followed by epidural normal saline bolus (www.chictr.org.cn, registration number: ChiCTR-ROC-17013382).

Abstract
OBJECTIVE To describe the surgical technique of direct anterior approach to total hip arthroplasty and to report the early clinical outcomes. METHODS A series of 100 consecutive, unselected patients who had 116 primary total hip arthroplasty surgeries (16 bilateral) done through direct anterior approach from March 11 2015 to June 21 2016 was reviewed. There were 50 male patients and 50 female patients. The average patient age was 51 years, and the average body mass index was 24.69 kg/m2. The preoperative diagnosis included avascular necrosis of femoral head, hip osteoarthritis, osteoarthritis secondary to acetabular dysplasia, sequelae of hip old infection, ankylosing spondylitis, rheumatoid arthritis and avascular necrosis of femoral head after cannulated screws fixation of femoral neck fracture. There were 7 hips which had surgical history prior to the index hip arthroplasty, including 3 cases with bone graft treatment for avascular necrosis of femoral head through Smith-Peterson approach, 2 cases with acetabular shelf procedures for acetabular dysplasia through Smith-Peterson approach, and 2 cases with cannulated screws fixation for femoral neck fracture (internal fixation residual). All were uncemented hips. The stems used in this study included 67 Triloc stems (DePuy company, USA), 45 Corail stems (DePuy company, USA), 2 Accolade stems (Stryker company, USA), 1 Synergy stem (Smith-Nephew company, USA) and 1 Polarstem (Smith-Nephew company, USA). RESULTS The average follow up period was 8.5 months, the average incision scar length was 10 cm, and the average postoperative Harris score was 93.62. There was 95% postoperative leg length discrepancy within 3 mm. The average cup inclination angle was 38.7° with 94.8% in the range of 30° to 50°. The average cup anteversion angle was 14.3° with 94.2% within the target range of 5° to 25°.The were 15 (12.9%) operative complications, including two femoral perforations (changing stem from Triloc to Corail), three calcar fractures (treated with cerclage wires), four greater trochanter fractures (2 were treated wire tension band, and 2 nondisplaced fractures untreated), one deep infection (debridement and retaining of the prothesis), one superficial infection (debridement), one hematoma and three wound healing complications (debridement). All the complications were successfully treated without any sequelae at the end of the latest follow-up. There was no postoperative dislocation. There was no major nerve and vascular injuries. There were 35 cases (30.2%) reporting symptoms of lateral femoral cutaneous nerve palsy. CONCLUSION Direct anterior approach to total hip arthroplasty allows accurate and reproducible cup orientation positioning and leg length restoration and decreases the risk of postoperative dislocation, which is helpful for early rapid postoperative recovery.

Abstract
OBJECTIVE To analyze the operation technique and the methods to avoid early complications on the learning curve for bilateral direct anterior approach (DAA) total hip arthroplasty (THA). METHODS We retrospectively studied a series of continued cases with bilateral avascular necrosis of the femoral head (AVN) or degenerative dysplastic hip and rheumatoid arthritis that were treated by DAA THA in Beijing Jishuitan Hospital. A total of 22 patients with 44 hips were analyzed from June 2014 to August 2016 in this study. There were 17 males and 5 females, and the median age was 48 years (range: 34-67 years). All the surgery was done by DAA method by two senior surgeons. The clinic characters, early surgery treatment results and complications were analyzed. RESULTS We used the cementless stems in all the cases. The average operating time was (167±23) min; the average blood loss was (775±300) mL;the blood transfusion was in average (327±341) mL; the wound drainage in average was (111±73) mL. Most of the patients could move out of the bed by themselves on the first day after operation, 5 patients could walk without crutches on the first operating day, and 13 patients could squat on the third days after operation. The patients were discharged averagely 4 days after operation. We followed up all the patients for averagely 16 months (range: 8-24 months). There was no loosening or failure case in the latest follow up. In the study, 2 patients had great trochanter fracture, 2 patients had thigh pain, 4 patients had lateral femoral cutaneous nerve palsy, and 3 patients had muscle damage. The Harris scores were improved from 29±8 preoperatively to 90±3 postoperatively (P<0.01). CONCLUSION The DAA THA can achieve faster recovery and flexible hip joint after operation. However it is a kind of surgery with high technique demanding. Carefully selected patients, and skilled technique, can help the surgeon avoid the early complications. It is associated with high complication rate in the learning curve for bilateral DAA THA.

Abstract
OBJECTIVE Recent evidence suggests a role of fibrogenesis in intervertebral disc (IVD) degeneration. We aim to explore if fibrotic genes may serve as IVD degeneration indicators, and if their expression is associated with myofibroblast activity. DESIGN Transcriptional expression of fibrosis markers (COL1A1, COL3A1, FN1, HSP47, MMP12, RASAL1) were analyzed in degenerated (D) and non-degenerated (ND) human nucleus pulposus (NP) and annulus fibrosus (AF) cells, along with traditional (SOX9, ACAN) and newly established degeneration markers (CDH2, KRT19, KRT18, FBLN1, MGP, and COMP). Protein expression was investigated by immunohistochemistry in human IVDs, and in rodent IVDs undergoing natural ageing or puncture-induced degeneration. Co-expression with myofibroblast markers was examined by double staining on human and rat specimens. Disc degeneration severity and extent of fibrosis were determined by histological scoring and picrosirius red staining respectively. RESULTS Human D-NP showed more intensive staining for picrosirius red than ND-NP. Among the genes examined, D-NP showed significantly higher MMP12 expression along with lower KRT19 expression. Protein expression analysis revealed increased MMP12(+) cells in human D-IVD. Histological scoring indicated mild degeneration in the punctured rat discs and discs of ageing mouse. Higher MMP12 positivity was found in peripheral NP and AF of the degenerative rat discs and in NP of the aged mice. In addition, human D-NP and D-AF showed increased α-SMA(+) cells, indicating enhanced myofibroblast activity. MMP12 was found co-expressed with α-SMA, FSP1 and FAP-α in human and rat degenerative IVDs. CONCLUSIONS Our study suggests that in addition to a reduced KRT19 expression, an increased expression of MMP12, a profibrotic mediator, is characteristic of disc degenerative changes. Co-expression study indicates an association of the increased MMP12 positivity with myofibroblast activity in degenerated IVDs. Overall, our findings implicate an impact of MMP12 in disc cell homeostasis. The precise role of MMP12 in IVD degeneration warrants further investigation.

Abstract
Detailed understanding of the mechanistic steps underlying tumor initiation and malignant progression is critical for insights of potentially novel therapeutic modalities. Cellular reprogramming is an approach of particular interest because it can provide a means to reset the differentiation state of the cancer cells and to revert these cells to a state of non-malignancy. Here, we investigated the relationship between cellular differentiation and malignant progression by the fusion of four independent mouse cancer cell lines from different tissues, each with differing developmental potentials, to pluripotent mouse embryonic stem (ES) cells. Fusion was accompanied by loss of differentiated properties of the four parental cancer cell lines and concomitant emergence of pluripotency, demonstrating the feasibility to reprogram the malignant and differentiative properties of cancer cells. However, the original malignant and differentiative phenotypes re-emerge upon withdrawal of the fused cells from the embryonic environment in which they were maintained. cDNA array analysis of the malignant hepatoma progression implicated a role for Foxa1, and silencing Foxa1 prevented the re-emergence of malignant and differentiation-associated gene expression. Our findings support the hypothesis that tumor progression results from deregulation of stem cells, and our approach provides a strategy to analyze possible mechanisms in the cancer initiation.

Abstract
OBJECTIVE To find out whether it is accurate to estimate femoral version based on femoral broach after femoral neck osteotomy using computed tomography scans. METHODS In 32 total hip arthroplasty (THA), we performed CT scans before and after operation. Four possible levels (lesser trochanter, 5 mm above, 10 mm above and 15 mm above the lesser trochanter) of broach version were calculated based on the preoperative CT scan. Stem versions were measured on the postoperative CT scan. We determined the difference between the preoperative broach version and the postoperative stem version using the Student's t test for paired samples assuming equal variance. RESULTS For the operated hips, preoperative hip version differed according to the level of measurement. Our findings showed that the average femoral version was 37.0°±11.0° at the level of the lesser trochanter (section 1), 34.3°±10.6° at 5 mm above the lesser trochanter (section 2), 28.1°±10.9° at 10 mm above the lesser trochanter (section 3), and 22.4°± 13.7° at 15 mm above the lesser trochanter (section 4), and that the average version for the femoral neck (FNV) was 12.9°±13.8°. The postoperative hip version was the stem version (FSV), which we found to be an average of 26.1°±11.0°. The mean femoral version for section 1 and 2 was larger than the mean postoperative stem version (P<0.01); the mean version for sections 3 and 4 did not differ from the mean postoperative stem version (P>0.05). The mean femoral neck version was less than the mean postoperative stem version (P<0.01); the difference was 13.2°±11.1° of the increased anteversion on average for the FSV compared with FNV. CONCLUSION The accuracy of estimated femoral version after arthroplasty depends on broach level. When it is 10 mm above the lesser trochanter, stem version estimation is accurate, but below that level, there is a tendency to overestimate.

Abstract
This study discusses the changes of T helper cells (Th cells) of patients who received different anesthesia methods in liver cancer resection. We selected 122 patients who were diagnosed with hepatocellular carcinoma and underwent liver cancer resection and divided them into a general anesthesia combined with epidural anesthesia group (group A) and general anesthesia group (group B). Peripheral blood was collected to detect Th cells on the day of surgery, and on the second and seventh days after surgery. Th1 and Th2 cell frequency and mRNA expression of interferon-γ (IFN-γ) of all patients significantly rose on the second day but recovered to the previous level on the seventh day. Th1/Th2 increased remarkably on the seventh day compared to the second day. Compared to the day of surgery, Th17, regulatory T (Treg)cells as well as mRNA expression of interleukin-17 (IL-17) and FoxP3 had no obvious changes on the second day, but dramatically declined on the seventh day. Compared to group B, Th1 cell frequency and Th1/Th2 in group A had a slight increase on the second day, and a remarkable increase on the seventh day; but Th2, Th17 and Treg cell frequency in group A slightly decreased on the second day and remarkably decreased on the seventh day. mRNA of IFN-γ, cytokine levels and IFN-γ/IL-4 of group A were all higher than group B on the seventh day, while mRNA of IL-17, concentration of IL-17 as well as concentration of transforming growth factor-β1 (TGF-β1) in group A were much lower than group B. These findings suggest that improving antitumor activity of Th cells can benefit patients who receive liver cancer resection.

Abstract
We report a study of the process e^{+}e^{-}→(D^{*}D[over ¯]^{*})^{0}π^{0} using e^{+}e^{-} collision data samples with integrated luminosities of 1092 pb^{-1} at sqrt[s]=4.23 GeV and 826 pb^{-1} at sqrt[s]=4.26 GeV collected with the BESIII detector at the BEPCII storage ring. We observe a new neutral structure near the (D^{*}D[over ¯]^{*})^{0} mass threshold in the π^{0} recoil mass spectrum, which we denote as Z_{c}(4025)^{0}. Assuming a Breit-Wigner line shape, its pole mass and pole width are determined to be (4025.5_{-4.7}^{+2.0}±3.1) MeV/c^{2} and (23.0±6.0±1.0) MeV, respectively. The Born cross sections of e^{+}e^{-}→Z_{c}(4025)^{0}π^{0}→(D^{*}D[over ¯]^{*})^{0}π^{0} are measured to be (61.6±8.2±9.0) pb at sqrt[s]=4.23 GeV and (43.4±8.0±5.4) pb at sqrt[s]=4.26 GeV. The first uncertainties are statistical and the second are systematic.

Abstract
The c-Jun NH2-terminal protein kinase (JNK) pathway has been implicated in mammary tumor development. However, the molecular mechanisms regulating JNK activity in breast cancer cells remain unclear. Here, we report that the inhibition of ubiquitination-like post-translational modification neddylation through different strategies results in enhanced basal JNK phosphorylation in human breast cancer cells. The upregulation of basal JNK phosphorylation upon neddylation inhibition is independent of the deneddylation of Cullins, the well-characterized neddylation substrates. Since augmented basal JNK phosphorylation via ectopic MKK7 expression impedes proliferation and the epithelial-to-mesenchymal transition (EMT) phenotype, the neddylation system might contribute to mammary tumor development partially through limiting basal JNK phosphorylation. Further exploration reveals that MKK7, a JNK-specific MAP2K, undergoes neddylation in human breast cancer cells. MKK7 co-precipitates with a fragment of Ran-binding protein 2 (RanBP2), a large multimodular and pleiotropic protein that has been recognized as a SUMO E3 ligase. Knockdown of RanBP2 attenuates MKK7 neddylation and augments basal JNK phosphorylation without affecting the neddylation of Cullins, whereas ectopic expression of a RanBP2 fragment possessing SUMO E3 activity (RanBP2ΔFG) manifests the opposite effects. In vitro neddylation assays confirm that RanBP2ΔFG works as the neddylation E3 ligase for MKK7. The basal kinase activity of endogenous MKK7 increases upon RanBP2 knockdown but decreases upon the ectopic expression of RanBP2ΔFG. Furthermore, purified MKK7 shows reduced basal kinase activity after in vitro neddylation by RanBP2ΔFG. Consistently, RanBP2 knockdown leads to reduced proliferation and impaired EMT phenotype in human breast cancer cells and the effects of RanBP2 knockdown are reversed by simultaneous MKK7 knockdown. Taken together, our data suggest that MKK7 undergoes neddylation in human breast cancer cells, which limits its basal kinase activity.

Abstract
Using a data sample collected with the BESIII detector operating at the BEPCII storage ring, we observe a new neutral state Z_{c}(3900)^{0} with a significance of 10.4σ. The mass and width are measured to be 3894.8±2.3±3.2 MeV/c^{2} and 29.6±8.2±8.2 MeV, respectively, where the first error is statistical and the second systematic. The Born cross section for e^{+}e^{-}→π^{0}π^{0}J/ψ and the fraction of it attributable to π^{0}Z_{c}(3900)^{0}→π^{0}π^{0}J/ψ in the range E_{c.m.}=4.19-4.42 GeV are also determined. We interpret this state as the neutral partner of the four-quark candidate Z_{c}(3900)^{±}.

Abstract
We report an observation of the process J/ψ→γX(1835)→γK_{S}^{0}K_{S}^{0}η at low K_{S}^{0}K_{S}^{0} mass with a statistical significance larger than 12.9σ using a data sample of 1.31×10^{9} J/ψ events collected with the BESIII detector. In this region of phase space the K_{S}^{0}K_{S}^{0} system is dominantly produced through the f_{0}(980). By performing a partial wave analysis, we determine the spin parity of the X(1835) to be J^{PC}=0^{-+}. The mass and width of the observed X(1835) are 1844±9(stat)_{-25}^{+16}(syst) MeV/c^{2} and 192_{-17}^{+20}(stat)_{-43}^{+62}(syst) MeV, respectively, which are consistent with the results obtained by BESIII in the channel J/ψ→γπ^{+}π^{-}η^{'}.

Abstract
We report the observation of the X(3823) state in the process e+e-→π+π-X(3823)→π+π-γχc1 with a statistical significance of 6.2σ, in data samples at center-of-mass energies sqrt[s]=4.230, 4.260, 4.360, 4.420, and 4.600 GeV collected with the BESIII detector at the BEPCII electron positron collider. The measured mass of the X(3823) state is (3821.7±1.3±0.7) MeV/c2, where the first error is statistical and the second systematic, and the width is less than 16 MeV at the 90% confidence level. The products of the Born cross sections for e+e-→π+π-X(3823) and the branching ratio B[X(3823)→γχc1,c2] are also measured. These measurements are in good agreement with the assignment of the X(3823) state as the ψ(1 3D2) charmonium state.

Enrichment of committed human nucleus pulposus cells expressing chondroitin sulfate proteoglycans under alginate encapsulation. Osteoarthritis Cartilage 2015; 23:1194-203.

Abstract
OBJECTIVE Intervertebral disc (IVD) degeneration is associated with a malfunction of the nucleus pulposus (NP). Alginate culturing provides a favorable microenvironment for the phenotypic maintenance of chondrocyte-like NP cells. However, NP cells are recently evidenced to present heterogeneous populations, including progenitors, fibroblastic cells and primitive NP cells. The aim of this study is to profile the phenotypic changes of distinct human NP cells populations and describe the dynamic expression of chondroitin sulfate glycosaminoglycans (CS-GAGs) in extended alginate encapsulation. METHOD Non-degenerated (ND-NPC) and degenerated (D-NPC) NP cells were expanded in monolayers, and subject to 28-day culture in alginate after serial passaging. CS-GAG compositional expression in monolayer-/alginate-cultured NP cells was evaluated by carbohydrate electrophoresis. Cellular phenotypic changes were assessed by immunologic detection and gene expression analysis. RESULTS Relative to D-NPC, ND-NPC displayed remarkably higher expression levels of chondroitin-4-sulfate GAGs over the 28-day culture. Compared with monolayer culture, ND-NPC showed increased NP marker expression of KRT18, KRT19, and CDH2, as well as chondrocyte markers SOX9 and MIA in alginate culture. In contrast, expression of fibroblastic marker COL1A1, COL3A1, and FN1 were reduced. Interestingly, ND-NPC showed a loss of Tie2+ but gain in KRT19+/CD24+ population during alginate culture. In contrast, D-NPC showed more consistent expression levels of NP surface markers during culture. CONCLUSION We demonstrate for the first time that extended alginate culture selectively enriches the committed NP cells and favors chondroitin-4-sulfate proteoglycan production. These findings suggest its validity as a model to investigate IVD cell function.

Abstract
OBJECTIVE To evaluate the effectiveness of conducting multiple arthroplasty to treat multiple joints disease in terms of quality of life (QOL) and function improvement. METHODS We compared our results with the reported results of single and dual arthroplasty to see if there is any improvement in QOL, functional scores or complications. In this study, 13 patients admitted to Department of Adult Reconstructive Surgery, Beijing Jishuitan hospital from 2005 to 2009 were included. Questionnaires SF-36 were used to evaluate the QOL. Harris hip score, American Knee Society Score (KSS) were used to evaluate the joint function. The patients were evaluated before surgery to the latest follow up. RESULTS SF-36 has changed as follow: physical function 4.17 ± 14.43 → 65.83 ± 24.76, role physical 25.00 ± 26.11 → 60.42 ± 45.8, bodily pain 23.83 ± 21.41 → 76.88 ± 20.89, general health 53.33 ± 33.87 → 76.67 ± 14.67, vitality 50.42 ± 17.25 → 71.67 ± 16.28, social functioning 29.17 ± 33.50 → 73.96 ± 33.90, role emotional 22.08 ± 35.61 → 77.77 ± 41.03, mental health 53.33 ± 25.70 → 82.67 ± 14.41, which indicated that they all improved greatly after the surgery (P < 0.05). Harris score increased from 37.68 ± 14.71 before the surgery to 83.36 ± 13.54 after the surgery. KSS has also showed sharp improvement (P < 0.001) in both clinical score (42.52 ± 23.83 → 77.74 ± 20.67) and function score (-2.61 ± 22.56 → 65.65 ± 30.76). CONCLUSION Multiple arthroplasty is one of the most effective methods which can markedly improve the quality of life in patients with multiple joints disease. But complications are common and joint functions are relatively poor.

Abstract
Based on data samples collected with the BESIII detector at the BEPCII collider at nine center of mass energies from 4.21 to 4.42 GeV, we search for the production of e^{+}e^{-}→ωχ_{cJ} (J=0, 1, 2). The process e^{+}e^{-}→ωχ_{c0} is observed for the first time, and the Born cross sections at sqrt[s]=4.23 and 4.26 GeV are measured to be (55.4±6.0±5.9) and (23.7±5.3±3.5) pb, respectively, where the first uncertainties are statistical and the second are systematic. The ωχ_{c0} signals at the other seven energies and the e^{+}e^{-}→ωχ_{c1} and ωχ_{c2} signals are not significant, and the upper limits on the cross sections are determined. By examining the ωχ_{c0} cross section as a function of center of mass energy, we find that it is inconsistent with the line shape of the Y(4260) observed in e^{+}e^{-}→π^{+}π^{-}J/ψ. Assuming the ωχ_{c0} signals come from a single resonance, we extract the mass and width of the resonance to be (4230±8±6) MeV/c^{2} and (38±12±2) MeV, respectively, and the statistical significance is more than 9σ.

Abstract
Joint detection of anti-dsDNA antibodies, anti-U1RNP, anti-SM antibodies, anti-SSA antibodies, anti-ribosomal P protein antibodies, anti-nucleosome antivodies (Anua), anti-histone antibodies (AHA) and antinuclear antibodies brings to the early diagnosis of systemic lupus erythematosus (SLE) and speculation of renal lesion degree of lupus nephritis patients in order to choose a specific therapeutic schedule. This paper analyzed the abnormal immunology features and connections of each pathological pattern of LN renal biopsy and probed into the essence in order to provide basis for diagnosis, treatment, pathological pattern speculation and forward assessment of LN. We chose 97 cases, treated them with renal biopsy and pathological pattern classification, analyzed pathological pattern distribution, different pathological patterns and the correlation of immunity index with anti-dsDNA antibodies, anti-U1RNP, anti-Sm antibodies, anti-SSA antibodies, anti-ribosomal P protein antibodies, Anua, AHA and ANA of the first renal biopsy were taken as the experiment index. The results showed that the morbidity of the male was distinctly lower than the female and the age of onset was much lower (P < 0.05); pattern I, pattern II, pattern III, pattern IV, pattern V, and pattern VI accounted for 1.0%, 3.1%, 12.4%, 47.4%,16.5%, 15.5%, 4.1%, 0%,respectively; among all the LN patients, there were respectively 59, 43, 28, 52, 51, 48, 36 and 93 cases in which anti-dsDNA antibody, anti-U1RNP antibody, anti-Sm antibody, anti-SSA antibody, anti-ribosomal P protein antibodies, Anua, AHA and ANA had increased and the positive rate was 60.8%, 44.3%, 28.9%, 53.6%, 52.6%, 49.5%, 37.1% and 95.9%, respectively. In conclusion, pattern IV is the most common of all pathological patterns of LN. Among the immunity index, anti- U1RNP antibodies and anti-SSA antibodies are positively correlated with anti-dsDNA antibodies; Anua is positively correlated with anti-dsDNA antibodies and AHA; anti-dsDNA antibodies, anti U1RNP antibodies, anti-Sm antibodies, anti SSA antibodies, AHA, anti-ribosomal P protein antibodies and ANA have no obvious correlation with LN renal lesions degree; Anua level of serum is positively correlated with LN renal lesions degree.

Abstract
The human breast cancer-associated gene (BCA3) was first discovered in breast and prostate cancer cells lines. In vivo studies have shown that BCA3 is mainly expressed in breast tumor cells and not in normal breast and prostate tissues. To date, 3 splice variants of BCA3 have been reported: a double-absent variant lacking exon 3 and exon 5 (BCA3-1), an exon 3-absent variant (BCA3-2), and full-length BCA3. In this study, we investigated whether a novel BCA3 splice variant exists that lacks only the exon 5-encoding sequence. BCA3 variant splices were subcloned and sequenced using reverse transcription-polymerase chain reaction. The preliminary biological functions of the splices were identified using confocal microscopy and a luciferase assay. The absence of exon 3 and exon 5 influenced the subcellular localization of BCA3 and nuclear factor kappa B (NF-kB)-dependent gene expression. Exon 3 and exon 5 of BCA3 may function together to provide a nuclear localization signal or transport sequence to enter the nucleus, and exon 3 may contain specific sequence(s) or domain(s) that influence the NF-κB signal cascade. The discovery of novel BCA3 splicing indicates a new cancer research area, which may increase the understanding of cancer generation and development.

Abstract
Using data collected with the BESIII detector operating at the Beijing Electron Positron Collider at center-of-mass energies of sqrt[s]=4.23, 4.26, and 4.36 GeV, we observe e(+)e(-)→π(0)π(0)hc for the first time. The Born cross sections are measured and found to be about half of those of e(+)e(-)→π(+)π(-)hc within less than 2σ. In the π(0)hc mass spectrum, a structure at 4.02 GeV/c(2) is found. It is most likely to be the neutral isospin partner of the Zc(4020)(±) observed in the process of e(+)e(-)→π(+)π(-)hc being found. A fit to the π(0)hc invariant mass spectrum, with the width of the Zc(4020)(0) fixed to that of its charged isospin partner and possible interferences with non-Zc(4020)(0) amplitudes neglected, gives a mass of (4023.9±2.2±3.8) MeV/c(2) for the Zc(4020)(0), where the first error is statistical and the second systematic.
