Abstract
Lung cancer is a major public health problem worldwide, with high rates of morbidity and mortality. It often coexists with chronic obstructive pulmonary disease (COPD), the diagnosis and management of which often receives insufficient attention. In particular, the presence of COPD has significant implications for the clinical management of lung cancer patients. This review systematically assesses the influence of COPD on the efficacy of immunotherapy and the occurrence of immune-related adverse events in patients with lung cancer, identifies existing challenges and proposes avenues for future research in this field.

Abstract
Dentin dysplasia type Ⅱ (DD-Ⅱ) is a subtype of hereditary dentin disorders. The dentin sialophosphoprotein (DSPP) gene has been revealed to be the causative gene, whose mutations could affect the normal tooth development process. The lesions involve both deciduous and permanent dentition, mainly manifested as tooth discoloration, attrition and even the subsequent malocclusion. If not treated in time, it will significantly affect the physical and psychological health of patients. The disease is difficult to be diagnosed in clinic accurately as its low incidence and hidden manifestations. The present article aims to discuss the clinical and radiographic characteristics, diagnosis, treatment of DD-Ⅱ, in order to improve the overall understanding on DD-Ⅱ for clinicians.

Abstract
The biological samples of oral genetic diseases and rare diseases are extremely precious. Collecting and preserving these biological samples are helpful to elucidate the mechanisms and improve the level of diagnose and treatment of oral genetic diseases and rare diseases. The standardized construction of biobanks for oral genetic diseases and rare diseases is important for achieving these goals. At present, there is very little information on the construction of these biobanks, and the standards or suggestions for the classification and coding of biological samples from oral and maxillofacial sources, and this is not conducive to the standardization and information construction of biobanks for special oral diseases. This consensus summarizes the background, necessity, principles, and key points of constructing the biobank for oral genetic diseases and rare diseases. On the base of the group standard "Classification and Coding for Human Biomaterial" (GB/T 39768-2021) issued by the National Technical Committee for Standardization of Biological Samples, we suggest 76 new coding numbers for different of biological samples from oral and maxillofacial sources. We hope the consensus may promote the standardization, and smartization on the biobank construction as well as the overall research level of oral genetic diseases and rare diseases in China.

Abstract
Immunoglobulins (Igs) are important effector molecules that mediate humoral immunity. A typical Ig consists of two heavy and two light chains. In teleosts, three Ig heavy chain isotypes (Igμ, Igδ and Igτ) and three Ig light chain isotypes (Igκ, Igλ and Igσ) have been identified. Compared to the heavy chains, teleost Ig light chains have been poorly studied due to the lack of antibodies. In this study, a mouse anti-Nile tilapia Igλ monoclonal antibody (mAb) was prepared, which could specifically recognize Igλ in serum and Igλ+ B cells in tissues. Further, the composition of IgM+ and Igλ+ B cell subsets was analyzed using this antibody and a mouse anti-tilapia IgM heavy chain mAb. The ratio of IgM+Igλ+ B cells to total IgM+ B cells in head kidney and peripheral blood was about 30%, while that in spleen was about 50%; the ratio of IgM-Igλ+ B cells to total Igλ+ B cells in head kidney and peripheral blood was about 45%, while that in spleen was about 25%. The IgM-Igλ+ B cells was speculated to be IgT+ B cells. Finally, we detected an increase in the level of specific antibodies against the surface antigen-Sip of Streptococcus agalactiae in serum after S. agalactiae infection, indicating that mouse anti-tilapia Igλ mAb can be used to detect the antibody level after immunization of Nile tilapia, which lays a foundation for the evaluation of immunization effect of tilapia vaccine.

Abstract
Objective: To investigate the etiology, prevention and treatment status, and their corresponding regional differences of the patients with liver cirrhosis in China, in order to provide scientific basis for the development of diagnosis and control strategies in China. Methods: Clinical data of patients diagnosed with liver cirrhosis for the first time through January 1, 2018 to December 31, 2020 from 50 hospitals in seven different regions of China were collected and analyzed retrospectively, and the difference of etiology, treatment, and their differences in various regions were analyzed. Results: A total of 11 861 cases with liver cirrhosis were included in the study. Thereinto, 5 093 cases (42.94%) were diagnosed as compensated cirrhosis, and 6 768 cases (57.06%) had decompensated cirrhosis. Notably, 8 439 cases (71.15%) were determined as chronic hepatitis B-caused cirrhosis, 1 337 cases (11.27%) were alcoholic liver disease, 963 cases (8.12%) were chronic hepatitis C, 698 cases (5.88%) were autoimmune liver disease, 367 cases (3.09%) were schistosomiasis, 177 cases (1.49%) were nonalcoholic fatty liver, and 743 cases (6.26%) of other types of liver disease. There were significant differences in the incidence of chronic hepatitis B, chronic hepatitis C, alcoholic liver disease, fatty liver, schistosomiasis liver disease, and autoimmune liver disease among the seven regions (P<0.001). Only 1 139 cases (9.60%) underwent endoscopic therapy, thereinto, 718 cases (6.05%) underwent surgical therapy, and 456 cases (3.84%) underwent interventional therapy treatment. In patients with compensated liver cirrhosis, 60 cases (0.51%) underwent non-selective β receptor blockers(NSBB), including 59 cases (0.50%) underwent propranolol and 1 case (0.01%) underwent carvedilol treatment. In patients with decompensated liver cirrhosis, 310 cases (2.61%) underwent NSBB treatment, including 303 cases (2.55%) underwent propranolol treatment and 7 cases (0.06%) underwent carvedilol treatment. Interestingly, there were significant differences in receiving endoscopic therapy, interventional therapy, NSBB therapy, splenectomy and other surgical treatments among the seven regions (P<0.001). Conclusion: Currently, chronic hepatitis B is the main cause (71.15%) of liver cirrhosis in several regions of China, and alcoholic liver disease has become the second cause (11.27%) of liver cirrhosis in China. The three-level prevention and control of cirrhosis in China should be further strengthened.

Abstract
We studied the effect of fibroblast growth factor receptor 3 (FGFR3) inhibitor BGJ-398 on the differentiation of bone marrow mesenchymal stem cells (BM MSC) into osteoblasts in wild type (wt) mice and in animals with mutation in TBXT gene (mt) and possible differences in the pluripotency of these cells. Cytology tests showed that the cultured BM MSC could differentiate into osteoblasts and adipocytes. The effect of different BGJ-398 concentrations on the expression of FGFR3, RUNX2, SMAD1, SMAD4, SMAD5, SMAD6, SMAD7, and SMAD8 were studied by quantitative reverse transcription PCR. The expression of RUNX2 protein was evaluated by Western blotting. BM MSC of mt and wt mice did not differ in pluripotency and expressed the same membrane marker antigens. BGJ-398 inhibitor reduced the expression of FGFR3 and RUNX2. In BM MSC from mt and wt mice have similar gene expression (and its changing) in FGFR3, RUNX2, SMAD1, SMAD4, SMAD5, SMAD6, SMAD7, and SMAD8 genes. Thus, our experiments confirmed the effect of decreased expression of FGFR3 on osteogenic differentiation of BM MSC from wt and mt mice. However, BM MSC from mt and wt mice did not differ in pluripotency and are an adequate model for laboratory research.

Abstract
Circadian rhythm is regulated by circadian clock, which is formed by the body response to external cyclic stimuli through the endogenous circadian clock. Circadian rhythm disturbance is closely related to the risks of a variety of diseases, and its impact on oral health cannot be ignored. Exploring the relationship and related molecular mechanism between circadian rhythm and dental hard tissues development are helpful to deeply understand the pathogenesis of developmental defects on these tissues, which could provide a theoretical basis for prevention and treatment on disorders of dental hard tissues. In order to provide guidance for the disease prevention and treatment, based on the summarization of current research progress, this paper focuses on the involvement of biorhythm in the development of tooth hard tissues as well as the disturbance of circadian rhythm on the formation of enamel and dentin, and analyzes the related regulating mechanism of circadian rhythm and genes during the development of tooth hard tissues.

Abstract
Oleanolic acid has previously been shown to possess PI3K inhibitory activity, thus, the purpose of this work was to generate a series of derivatives that improve the potency. Twenty rationally designed oleanolic acid derivatives were synthesized and tested the cytotoxicity and PI3K inhibitory activity. The results suggested that attachment of additional structural elements such as association of thiazole group to A ring and insertion of phenylurea group was important for increasing activities. The most active derivative was compound II2, which exhibited PI3K inhibitory activity (IC50 = 58.42 nmol/l) and improved interaction with activity site of PI3K according with docking studies.

Abstract
Iron-catalyzed oxidative amination of benzylic C(sp3)-H bonds with anilines bearing electron-withdrawing groups (EWGs) or electron-donating groups (EDGs) is realized based on simple variations of N-substituents on imidazolium cations in novel ionic Fe(III) complexes. The structural modification of the imidazolium cation resulted in regulation of the redox potential and the catalytic performance of the iron metal center. Using DTBP as oxidant, [HItBu][FeBr4] showed the highest catalytic activity for anilines bearing EWGs, while [HIPym][FeBr4] was more efficient for EDG-substituted anilines. This work provides alternative access to benzylamines with the advantages of both a wide substrate scope and iron catalysis.

Abstract
Objective: To investigate the effect of guided bone regeneration (GBR) on marginal bone loss (MBL) in the region of the mandibular posterior tooth by using a retrospective cohort study, in order to provide reference for clinical practice. Methods: The research subjects were patients who received dental implants from October 2008 to June 2011 in the region of the mandibular posterior tooth at the Department of Oral Implantology, School of Stomatology, The Fourth Military Medical University. According to whether GBR was performed or not and the time of implant insertion, the patients were divided into the controls group (patients without bone grafting), simultaneous GBR implantation group, and delayed GBR implantation group. On this basis, the MBL was measured according to radiographs by comparing the marginal bone level from that of immediate postoperation 10 years ago. General data was collected and compared among groups, including modified plaque index (mPI), modified sulcus bleeding index (mSBI), probing depth (PD), and gingival papilla height. Results: The controls group (patients without bone grafting), implantation group, and delayed GBR implantation group followed 58, 76, 26 implants in 26, 32, 13 patients aging at (46.5±9.9), (45.5±10.7), (58.3±6.4) respectively. The duration of the follow-up was (11.2±0.7), (11.1±0.8), (11.1±0.9) years respectively. The 10-year implant survival rate was 100% (58/58), 100% (76/76), 100% (26/26). The MBL was (0.91±0.28), (0.84±0.27), (1.01±0.27) mm respectively. The MBL difference of patients with simultaneous GBR implantation and delayed GBR implantation showed statistical significance (P<0.05), but these two groups showed no statistical significance compared with the controls group (P>0.05). The mPI, mSBI, PD, and gingival papilla height of the three groups all had no significance on statistics (P>0.05). Conclusions: It can be concluded that there is no difference in long-term marginal bone resorption between simultaneous and delayed implantation with or without GBR (using autologous blood mixed with granular bone meal) in the posterior mandibular area.

Abstract
Diabetes mellitus is a relative contraindication of dental implant therapy, that limits the application of implant therapy severely. Diabetic status often leads to secondary vascular and bone lesions, which affect treatment adversely and lead to an increased failure rate. Therefore, how to implement implant therapy for diabetic patients has become a difficult question for dentists. According to the research and experience over the years on diabetic patients, and referring to the current research progress on this topic, the authors will discuss the clinical characteristics of diabetic patients and the details of treatment process, for reference.

Abstract
The intercellular adhesion molecule-1 (ICAM-1), known as CD54, is a transmembrane cell surface glycoprotein that interacts with two integrins (i.e., LFA-1 and Mac-l) important for trans-endothelial migration of leukocytes. The level of ICAM-1 expression is upregulated in response to some inflammatory stimulations, including pathogen infection and proinflammatory cytokines. Yet, to date, our knowledge regarding the functional role of ICAM-1 in teleost fish remains largely unknown. In this study, we cloned and characterized the sequence of ICAM-1 in rainbow trout (Oncorhynchus mykiss) for the first time, which exhibited that the molecular features of ICAM-1 in fishes were relatively conserved compared with human ICAM-1. The transcriptional level of ICAM-1 was detected in 12 different tissues, and we found high expression of this gene in the head kidney, spleen, gills, skin, nose, and pharynx. Moreover, upon stimulation with infectious hematopoietic necrosis virus (IHNV), Flavobacterium columnare G4 (F. columnare), and Ichthyophthirius multifiliis (Ich) in rainbow trout, the morphological changes were observed in the skin and gills, and enhanced expression of ICAM-1 mRNA was detected both in the systemic and mucosal tissues. These results indicate that ICAM-1 may be implicated in the mucosal immune responses to viral, bacterial, and parasitic infections in teleost fish, meaning that ICAM-1 emerges as a master regulator of mucosal immune responses against pathogen infections in teleost fish.

Abstract
In this study, twenty-four oleanolic acid (OA) derivatives were rationally designed based on molecule docking studies and their VEGFR-2 inhibitory activities were tested by Homogeneous time-resolved fluorescence (HTRF) method in vitro. All of the synthesized compounds were identified as new compounds, and the structures of these compounds were determined by 1H-NMR and ESI-MS. In the screening for VEGFR-2 inhibitors, compounds I6 and I7 exhibited excellent inhibitory effect. The results indicated that insertion of phenylurea group with a linker at position C-28 of OA can increase the activity against VEGFR-2 significantly. [Formula: see text].

Abstract
Objective: To explore the protective effect of human adipose-derived mesenchymal stem cells (AD-MSCs) and liraglutide on lipopolysaccharide (LPS) -induced acute lung injury (ALI) . Methods: AD-MSCs were cultured in vitro and randomly divided into 3 groups: control group, LPS group (30 mg/L) , and LPS (30 mg/L) +liraglutide (10 nM) group. MTT assay was used to detect the proliferation of AD-MSCs at 6, 24, 48 and 72 h. Annexin V-FITC / PI double staining flow cytometry was used to detect the apoptosis of the cells. Western blot was used to detect the expression of apoptotic proteins cleaved caspase-3, Bax and Bcl-2 at 72 h in vitro. For the in vivo experiment, 60 male SPF BALB/c mice were randomly divided into 5 groups: control group, ALI group, ALI+AD-MSCs group, ALI+Liraglutide group, and ALI+AD-MSCs+Lraglutide group. The mice were sacrificed on day 2 and day 7 after LPS treatment. HE staining was used to examine the pathological changes of the lungs of mice, and the scores of lung injury were measured. The lung tissues of mice were examined by immunohistochemistry, and the expression of the marker protein Nanog of mesenchymal stem cells was observed. BALF was collected, and the number of BALF neutrophils was counted by Rayleigh Giemsa staining. The wet/dry specific gravity of mouse lung tissue was recorded. Results: The apoptosis of AD-MSCs stimulated by LPS was significantly higher than that of the control group (P<0.05) , and the proliferation of AD-MSCs at 6, 24, 48 and 72 h was significantly lower than that of the control group (all P<0.05) . The addition of Liraglutide reduced the apoptosis of AD-MSCs (P<0.05) , and promoted the proliferation of AD-MSC at 6, 24, 48 and 72 h. Compared with the control group, in the 2 d and 7 d model groups, the lung injury pathology of ALI group had lung injury, increased number of neutrophils in BALF (65.63±1.34 vs 1.74±0.17, 51.67±1.35 vs 1.55±0.13) ×10(4)/ml (all P<0.05) , and increased W/D of lung tissues. The expression level of Nanog protein was low in the 7 d model group. Compared with the ALI group, in 2 d and 7 d model groups, the ALI+AD-MSCs group, the ALI+liraglutide group, and the ALI+AD-MSCs+liraglutide group showed reduced lung injury pathology, and the number of neutrophils was decreased, (37.04±1.23, 29.17±0.68) ×10(4) / ml (all P<0.05) in the ALI+AD -MSCs group, (39.58±1.67, 35.42±0.25) ×10(4) / ml in the ALI+Liraglutide group (all P<0.05) and (28.54±0.37, 21.46±0.89) ×10(4)/ml (all P<0.05) in the ALI+AD-MSCs+Liraglutide group. Lung tissue W/D in the ALI+AD-MSCs group, ALI+Liraglutide group and ALI+AD-MSCs+Liraglutide group showed the same trend. Nanog protein expression increased in the 7 d model group. Conclusions: AD-MSCs play a protective role in acute lung injury in mice under the synergistic effect of liraglutide.

Abstract
Fusarium graminearum is the primary causal agent of Fusarium head blight (FHB) of wheat. The phenylpyrrole fungicide fludioxonil is not currently registered for the management of FHB in China. The current study assessed the fludioxonil sensitivity of a total of 53 F. graminearum isolates collected from the six most important wheat-growing provinces of China during 2018 and 2019. The baseline fludioxonil sensitivity distribution indicated that all of the isolates were sensitive, exhibiting a unimodal cure with a mean effective concentration for 50% inhibition value of 0.13 ± 0.12 μg/ml (standard deviation). Five fludioxonil-resistant mutants were subsequently induced by exposure to fludioxonil under laboratory conditions. Ten successive rounds of subculture in the absence of the selection pressure indicated that the mutation was stably inherited. However, the fludioxonil-resistant mutants were found to have reduced pathogenicity, higher glycerol accumulation, and higher osmotic sensitivity than the parental wild-type isolates, indicating that there was a fitness cost associated with fludioxonil resistance. In addition, the study also found a positive cross resistance between fludioxonil, procymidone, and iprodione, but not with other fungicides such as boscalid, carbendazim, tebuconazole, and fluazinam. Sequence analysis of four candidate target genes (FgOs1, FgOs2, FgOs4, and FgOs5) revealed that the HBXT2R mutant contained two point mutations that resulted in amino acid changes at K223T and K415R in its FgOs1 protein, and one point mutation at residue 520 of its FgOs5 protein that resulted in a premature stop codon. Similarly, the three other mutants contained point mutations that resulted in changes at the K192R, K293R, and K411R residues of the FgOs5 protein but none in the FgOs2 and FgOs4 genes. However, it is important to point out that the FgOs2 and FgOs4 expression of all the fludioxonil-resistant mutants was significantly (P < 0.05) downregulated compared with the sensitive isolates (except for the SQ1-2 isolate). It was also found that one of the resistant mutants did not have changes in any of the sequenced target genes, indicating that an alternative mechanism could also lead to fludioxonil resistance.

Abstract
Objective:To analyze the secondary pulmonary infection and the distribution of pathogenic bacteria in children with tracheobronchial foreign body, and to guide the clinical treatment. Method:The clinical data of 197 children with tracheobronchial foreign bodies confirmed by rigid bronchoscopy were reviewed. According to the clinical manifestations and signs, blood routine, chest CT and airway endocrine pathogen distribution, the secondary pulmonary infection was analyzed. Result:Seventy-five of 197 children with foreign bodies in tracheobronchial had secondary pulmonary infections. Among them, 32 cases of airway endocrine cultured pathogenic bacteria, mainly including Streptococcus pneumoniae and Haemophilus influenzae. Children with long preoperative history, fever, and with a history of using antibiotics are more likely to have secondary pulmonary infections. Conclusion:The duration of disease history, preoperative fever and the use of antibiotics are related to secondary pulmonary infection. The third generation of cephalosporins can effectively control the infection.

Abstract
Objective: To discuss the therapeutic scheme of petrous bone cholesteatoma(PBC) and the technique of facial nerve reconstruction. Method: The data of 28 patients who underwent surgery for PBC in our center were analyzed retrospectively. All patients were diagnosed radiologically with PBCs and reconfirmed pathologically after surgery. The surgical approach was discussed basing Sanna's classification of PBCs, and the facial nerve outcomes were analyzed moreover. Result: PBC cases 11 were supralabyrinthine, 4 infralabyrinthine, 3 infralabyrinthine-apical, 10 massive and none apical. The facial nerve was involved in 50% of the cases. The translabyrinthine approach were used in 3 cases. The transotic approach was used in 7 cases in this series.The transcochlear approach type was applied in 12 cases. The Infratemporal fossa type B approach and subtotal petrosectomy were employed in 2 cases and 4 cases respectively. Active management of the nerve(rerouting, anastomosis, or grafting) was required in 14 cases, postoperative facial nerve function were inproved in 10 cases(71.43%). Conclusion: The appropriate surgery approach was vitally important to radical disease clearance in PBCs. The facial nerve preservation was preceded hearing preservation. Active facial nerve management were beneficial to facial nerve recovery..

Abstract
Objective:Retrospctive analysed the Characteristics and outcomes of surgical treatment of 18 patients who were diagnosed as secondary acquired cholesteatoma (SAC).Method:Patients with SAC accepted operations were enrolled in this study. Then the factors such as sex, age, cource of history, otorrhea before operation, the size of perforation of tympanic membrane, entry site of epithelium, extension direction, ossicular destruction, tympanosclerosis, tympanum tympani tendon involvement, stage of cholesteatoma(JOS, 2015, Japan),degree of gasification of mastoid(JOS,2015,Japan),air conductive threshold, bone conductive threshold, air-bone gap, the healing of tympanic membrane and the auditory improvement were analyzed.Result:Eighteen patients were enrolled in this study, with course of history range from 2 months to 50 years (average: 20.20±16.31) years. There were 14 cases with wet ear before operation. All patients were conformed with perforation of membranal tensa by otoendoscopic photography before operation, with nearly total in 5 ears,large size in 10 ears,medium size in 2 ears and small size in 1 ear. Ossicular erosion were found in 13 patients (malleus involved in 6, incus involved in 12 and stapes involved in 4). Thirteen patients with tendon of tensor tympani involved and 9 patients with tympanosclerosis were conformed during operation. The epithelium entered through the malleus manubrium to the promontory in 13 cases, through the edge of the perforation in 3 cases and through the incus long process to around stapes in 1 case. Cholesteatoma invasion extend to anterosuperior area in 3 cases, posterosuperior area in 3 cases,both in anterosuperior and posterosuperior area in 12 cases. The cholesteatomas classified: stage Ⅰ in 11 cases, stage Ⅱ in 7 cases. Mastoid gasification classified MC0 in 6 cases, MC1 in 10 cases and MC2 in 2 cases. The average air conductive threshold was (56.32±10.15) dB, bone conductive threshold was (20.76±6.22) dB and air-bone gap (35.56±9.84) dB.Tympanic membrane healed in all patients during following up, without recurrent of cholesteatoma, and the post-operative air conductive threshold (43.02±14.96) dB and air-bone gap (21.04±12.90)dB were improved significantly(P<0.05).Conclusion:Most of SAC were secondary to nearly total or large perforation of membranal tensa (83.33%), with relative long history of chronic otitis media (average 20.20 ± 16.31) years and otorrhea before operation. The epithelium entered mainly through the malleus manubrium to the promontory,then through edge of the perforation,by extending anterosuperior and posterosuperior area and usually accompanied with tendon of tensor tympani involved, ossicular destruction, and poor mastoid gasification and tympanosclerosis. The characteristics of SAC were different from other type of cholesteatoma which need further researches.

Abstract
Objective: To evaluate the effect of semaphorin 3A (Sema3A) pre-treated bone marrow mesenchymal stem cells (BMSC) sheets on new bone formation in type 2 diabetes mellitus rats. Methods: Type 2 diabetes mellitus (T2DM) were induced by injection of streptozotocin, and the BMSC were isolated, controlled, identified and induced into cell sheets. Fifteen T2DM rats were randomly divided into control, sheets and Sema3A-sheets group and the calvarial critical size defect (CSD) model of rats were established. The defect zone of rats from control group were implanted with bone powder. The defect zone of rats from sheets group were implanted with bone powder and BMSC sheets. The defect zone of rats from Sema3A-sheets group were implanted with bone powder and BMSC sheets pretreated with 1.0 mg/L Sema3A. After 8 weeks, the bone samples were harvested and analyzed by micro-CT scanning, HE staining for the evaluation of new bone formation, and the immunohistochemical analysis for the expression of osteogenesis-related proteins including type Ⅰ collagen (COL- Ⅰ ), bone morphogenetic protein-2 (BMP-2), and osteocalcin (OCN). Results: The BMSC were isolated and cultured, and oil red O and Alizarin red S staining proved the multi-potential differentiation. Eight weeks after the establishment of calvarial CSD model, Sema3A-sheet group showed the most abundant new bone formation (0.516±0.070), with increased bone volume fraction, namely bone volume/tissue volume (BV/TV) compared with sheets group (0.319±0.050) and control group (0.224±0.037) (P<0.05), and the sheets group showed increased BV/TV compared with control group (P<0.05). While trabecular thickness (Tb.Th) control group showed no difference in three groups (P>0.05). HE staining also confirmed that Sema3A-sheets group showed the most new bone formation. Sheet group (0.174±0.051) compared showed difference with control group (0.099±0.033) (P< 0.05), and Sema3A-sheet group (0.421±0.069) showed increased bone formation compared with sheet group and control group (P<0.05). Immunohistochemistry showed that BMSC sheet increased the expression of osteogenesis-related proteins including COL-Ⅰ, BMP-2 and OCN, while Sema3A pretreatment showed more obvious increase of the expression of COL-Ⅰ and OCN. Conclusions: The combined implantation of bone powder and Sema3A stimulated BMSC sheets significantly increased bone regeneration in vivo. Therefore, Sema3A pre-treated BMSC sheets transplantation provides a new strategy for restoring bone defect in T2DM.

Abstract
Objective: To analyze the clinical features of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma. Methods: A total of 14 cases diagnosed with primary pulmonary MALT lymphoma were collected from May 2007 to May 2017 in Zhongshan Hospital, Fudan University. The clinical features, pathological characteristics, diagnosis, treatment and prognosis were retrospectively analyzed. Results: All 14 cases were pathologically diagnosed with primary pulmonary MALT lymphoma. The biopsy tissues were obtained through the Video-assisted Thoracoscopic Surgery (VATS) (4 cases), percutaneous puncture (2 cases), and bronchoscopy (8 cases). Cell types of these tumors were centrocyte-like cells (10 cases), lymphocytoid cells (2 cases), and monocytoid B cells (2 cases). The B cell clonality was detected by IgH cloning test in 4 cases and 3 of them were demonstrated with monoclonal strips. MALT1 breakup gene was positive in 3 out of 6 examined cases using fluorescence in situ hybridization (FISH). As for the treatment, 8 patients underwent chemotherapy, 5 patients underwent surgical resection and 1 patient abandoned treatment. Twelve patients were followed up to 9 years. The tumor recurrence occurred in 2 patients and resulted their death. Conclusions: The clinical manifestations of primary pulmonary MALT lymphoma are lack of specificity. The pathology, immunohistochemistry, IgH cloning test and MALT1 breakup gene tested by FISH are the criteria for diagnosis.

Abstract
Objective: To investigate the value of preoperative dynamic contrast-enhanced MRI in reducing the rate of tumor-positive resection margins after breast conserving surgery in patients with early non-mass breast carcinoma. Methods: Seventy-two patients with early non-mass breast carcinoma received ultrasonographic and mammographic examination and subsequently underwent dynamic contrast-enhanced MRI examination before breast conserving surgery. The control group consisted of 74 patients who had early non-mass breast carcinoma. They only received ultrasonographic and mammographic examination and didn't undergo contrast-enhanced MRI examination. The comparison of the rate of tumor-positive resection margins between two groups was performed. The MRI findings that had the significant influence on the rate of tumor-positive resection margins were analyzed using Logistic regression model. Results: In 28 patients (28/72, 38.9%), dynamic contrast-enhanced MRI could correct or supplement the ultrasonographic and mammographic findings and resulted in the reasonable change of surgical program. The preoperative MRI examination group (n=30) had lower rate of tumor-positive resection margins than control group for invasive ductal carcinoma (23.3% vs 40.0%, P=0.02), but there was no significant difference (21.4% vs 26.9%, P=0.10) between two groups for ductal carcinoma in situ (n=28). The preoperative MRI examination group (n=14) had lower rate of tumor-positive resection margins than control group for the other pathologic types of breast carcinoma (14.3% vs 38.9%, P=0.02). The statistical analysis on the basis of Logistic regression model showed that some main MRI findings, including change surrounding the tumor, distance between tumor and nipple and tumor size, had the significant influence on the rate of tumor-positive resection margins. Conclusion: Preoperative dynamic contrast-enhanced MRI significantly increased the accuracy of resection margins evaluation, and greatly reduced the rate of tumor-positive resection margins after breast conserving surgery in patients with early non-mass breast carcinoma.

Abstract
Studies on elevational gradients in biodiversity have accumulated in recent decades. However, few studies have compared the elevational patterns of diversity between the different slopes of a single mountain. We investigated the elevational distribution of rodent diversity (alpha and beta diversity) and its underlying mechanisms along the southern and northern slopes of Mt. Taibai, the highest mountain in the Qinling Mountains, China. The species richness of rodents on the two slopes showed distinct distribution patterns, with a monotonically decreasing pattern found along the southern slope and a hump-shaped elevational pattern evident along the northern slope. Multi-model inference suggested that temperature was an important explanatory factor for the richness pattern along the southern slope, and the mid-domain effect (MDE) was important in explaining the richness pattern along the northern slope. The two slopes also greatly differed in the elevational patterns of species turnover, with the southern slope demonstrating a U-shaped curve and the northern slope possessing a roughly hump-shaped pattern. Our results suggest that even within the same mountain, organisms inhabiting different slopes may possess distinct diversity patterns, and the underlying mechanisms may also differ. The potential role of the factors associated with slope aspect in shaping diversity, therefore, cannot be ignored.

Abstract
Lymphangioleiomyomatosis (LAM) is a rare multisystem disease occurring almost exclusively in premenopausal women and characterized by cystic lung destruction, abdominal tumors (renal angiomyolipomas (AML)), and involvement of the axial lymphatics (adenopathy, lymphangioleiomyomas). Serum vascular endothelial growth factor-D (VEGF-D), a lymphangiogenic factor, has been recently considered as a novel marker for LAM. Herein we report the diagnostic and differential diagnostic value of serum VEGF-D in LAM patients and evaluate the change of serum VEGF-D levels before and after treatment with sirolimus. The study group included 66 patients with LAM (47 definite LAM and 19 probable LAM based on European Respiratory Society guidelines), 14 patients with other polycystic lung diseases, and 20 healthy female controls. Serum VEGF-D levels were quantified by enzyme-linked immunoassay (ELISA). Serum VEGF-D levels were significantly increased in definite LAM patients compared with healthy controls (3890.3±373.3 pg/ml vs. 413.3±33.2 pg/ml, p<0.05). The optimal cutoff point for LAM diagnosis was 692.5 pg/ml with sensitivity of 97.9% and specificity of 100%. In probable LAM patients, serum VEGF-D levels were all greater than 692.5 pg/ml. Serum VEGF-D levels were significantly increased in definite LAM patients who had chylothorax compared with those without chylothorax (5153.9±598.3 pg/ml vs. 2869.8±372.8 pg/ml, p<0.05). But serum VEGF-D levels in LAM patients with/without pneumothorax, AML, and lymphangioleiomyomas were not significantly changed. Serum VEGF-D levels in definite LAM patients and patients with other cystic lung diseases were 3890.3±373.3 pg/ml and 412.6±27.5 pg/ml, respectively (p <0.05). We determined an optimal cutoff value of 688.5pg/ml, resulting in sensitivity of 97.9% and specificity of 100%. Following a median of 12-month treatment with sirolimus, serum VEGF-D levels decreased from 3135.0±909.4 pg/ml to 1731.8±621.2 pg/ml and symptoms improved. Our study found that serum VEGF-D levels were significantly higher in LAM patients compared with healthy controls and patients with other polycystic lung diseases and that the levels were further increased when complicated by chylothorax. Serum VEGF-D levels may be useful for diagnosis and differential diagnosis with high specificity and sensitivity as well as for following treatment response with sirolimus.

Abstract
Small mammals play important roles in many ecosystems, and understanding their response to disturbances such as cattle grazing is fundamental for developing sustainable land use strategies. However, how small mammals respond to cattle grazing remains controversial. A potential cause is that most of previous studies adopt rather simple experimental designs based solely on the presence/absence of grazing, and are thus unable to detect any complex relationships between diversity and grazing intensity. In this study, we conducted manipulated experiments in the Hulunber meadow steppe to survey small mammal community structures under four levels of grazing intensities. We found dramatic changes in species composition in native small mammal communities when grazing intensity reached intermediate levels (0.46 animal unit/ha). As grazing intensity increased, Spermophilus dauricus gradually became the single dominant species. Species richness and diversity of small mammals in ungrazed and lightly grazed (0.23 animal unit/ha) area were much higher than in intermediately and heavily grazed area. We did not detect a humped relationship between small mammal diversity and disturbance levels predicted by the intermediate disturbance hypothesis (IDH). Our study highlighted the necessity of conducting manipulated experiments under multiple grazing intensities.

Abstract
The creation of nature reserves is the most direct way to save endangered species populations and their habitat. Development of the giant panda (Ailuropoda melanoleuca) nature reserve network in China was initiated in the 1960s, though the effort to create new reserves boomed considerably after the year 2000. Given this rapid development of protected areas in panda habitats, and the potential conflicting interests between conservation administrations and local economic development, it is essential to assess the role of new nature reserves in the overall giant panda conservation effort and reserve network. We utilized data from national giant panda surveys conducted in 2000 and 2012 to compare the size, spatial use, and distribution of panda populations, as well as the habitat suitability and connectivity in the Northern Qionglai Mountains between the two survey years. Our results show that although the total giant panda population in the study area did not change remarkably, local changes did occur. Most notably, the population in Wolong Nature Reserve declined by 27.3% (N = 39) and the population in Caopo Nature Reserve increased by 71.4% (N = 29) over the 12-year study period. We also found habitat suitability and availability decreased in both Wolong (12.4%) and Caopo (7.4%), but that the relative density of giant pandas declined (19.2%) and increased (84.6%) at each site, respectively. The distance between centers of high IUA were more distant in 2012 (14.1±1.9km) than that in 2000 (6.1±0.9km; t = -7.4, df = 5, p = 0.001), showing a scattered spatial pattern. Habitat availability decreased by 42% within the corridor between the two reserves, however panda occurrences in the corridor increased 24.6%. Compared to the total number of encounters, the proportion of the corridor increased 45.76%. Our results show the importance and success of the newly established Caopo to the conservation of giant pandas, and how crucial it is to identify and repair reserve corridors. Furthermore, we propose criteria for future nature reserve network management and investment, which is applicable for other endangered species conservation practices.

Abstract
BACKGROUND Many anesthesia methods have been studies in hepatocellular carcinoma (HCC). We aimed to explore the effects of combined intravenous and inhalation anesthesia and combined general and epidural anesthesia on cellular immune function and neuroendocrine function in patients with HCC before and after surgery. METHODS Between September 2012 and April 2014, 72 patients who underwent a hepatectomy in our hospital were enrolled. RESULTS Compared with the combined intravenous and inhalation anesthesia group, the combined general and epidural anesthesia group demonstrated increased CD4+ /CD8+ T cells 0 hr after surgery, increased CD3+ , CD4+ , CD4+ /CD8+ cells, and IFN-γ levels 12 hr after surgery, and increased CD3+ , CD4+ , and CD4+ /CD8+ cells 24 hr after surgery (all P < 0.05). At 72 hr after surgery, the levels of ACTH and Cor in the combined general and epidural anesthesia group, and the levels of CD3+ , CD4+ , CD4+ /CD8+ cells, and IFN-γ in both the combined intravenous and inhalation anesthesia and the combined general and epidural anesthesia groups decreased to pre-surgery levels. Significant differences were observed in the comparisons of CD3+ , IL-6, and IL-10 between the combined intravenous and inhalation anesthesia and the combined general and epidural anesthesia groups 72 hr after surgery (all P < 0.05). CONCLUSION Our results revealed that combined general and epidural anesthesia plays a crucial role in hepatectomy via the mitigation of the inhibition of immunologic function in HCC patients during the perioperative period. Combined general and epidural anesthesia also hastens the recovery of immunologic suppression after surgery, which can provide a certain reference for the selection of clinical anesthesia in the treatment of HCC.

Abstract
A cross-sectional cohort study was conducted to investigate whether ghrelin level in obese women predicts the quality of life (QOL). A total of 307 subjects fulfilled the criteria: (1) age between 20 and 65 years old, (2) body mass index ≥27 kg/m2 (3) waist circumference ≥80 cm were enrolled in the study. All subjects were assigned to one of the plasma ghrelin level categories according to the quartiles. The median of age and BMI of the 307 obese women were 45 ± 18 years and 29.9 ± 4.1 kg/m2, respectively. The main outcome evaluated is the associations of plasma ghrelin level and QOL, which were evaluated using multiple linear regression analysis. Results of linear trend test show significant statistical difference in plasma lipoproteins (triglyceride, cholesterol, HDL-cholestero and LDL-cholesterol = and levels of obesity-related hormone peptides, including leptin, adiponectin, insulin among quartiles of ghrelin. Multiple liner regression analysis of serum obesity-related hormone peptide level and QOL using stepwise method shows ghrelin concentration was the only predictor of QOL, including PCS-12 level (β = -0.18, p = 0.001), MCS-12 level (β = -0.14, p = 0.009), WHOQOL-BREF scores: physical (β = -0.13, p = 0.03), psychological (β = -0.16, p = 0.007), social (β = -0.21, p = < 0.001), and environmental (β = -0.22, p = <0.001), after adjusting other factors for obese female subjects. This study demonstrated that ghrelin concentration is strongly associated with QOL level among obese women. Hence, ghrelin concentration might be a valuable marker to be monitored in obese women.

Abstract
We studied the foraging behaviour of two sympatric rodents (Meriones meridianus and Dipus sagitta) in the Gobi Desert, Northwestern China. The role of the foraging behaviour in promoting species coexistence was also examined. We used giving-up densities (GUDs) in artificial food patches to measure the patch use of rodents and video trapping to directly record the foraging behaviour, vigilance, and interspecific interactions. Three potential mechanisms of coexistence were evaluated (1) microhabitat partitioning; (2) spatial heterogeneity of resource abundance with a tradeoff in foraging efficiency vs. locomotion; and (3) temporal partitioning on a daily scale. Compared to M. meridianus, D. sagitta generally possessed lower GUDs, spent more time on patches, and conducted more visits per tray per capita, regardless of microhabitat. However, M. meridianus possessed advantages in average harvesting rates and direct interference against D. sagitta. Our results only partly support the third mechanism listed above. We propose another potential mechanism of coexistence: a tradeoff between interference competition and safety, with M. meridianus better at interference competition and D. sagitta better at avoiding predation risk. This mechanism is uncommon in previously studied desert rodent systems.

Abstract
To date, no study has investigated the association between CYP1A2-163C/A polymorphism and bladder cancer risk in a Chinese population. Here, we extracted genomic DNA from peripheral white blood cells, and differentiated CYP1A2 alleles by polymerase chain reaction-based restriction fragment length polymorphism methods. Differences in genotype frequencies between the cases and controls were evaluated using a chi-square test. The odds ratio (OR) and its 95% confidence interval (CI) were calculated using an unconditional logistic regression model. This revealed that the -163A allele was present at a significantly increased frequency in bladder cancer patients compared to healthy controls (44.10 vs 22.25%, P < 0.001). The prevalence of CC genotype, CA genotype, and AA genotype was 34.91, 41.98, and 23.11% in bladder cancer patients, and 64.00, 27.50, and 8.5% in the controls, respectively. Therefore, significant differences in the frequencies of -163 genotypes were found between bladder cancer patients and controls (P < 0.001). We found that the AA genotype was significantly associated with increased bladder cancer risk (OR = 3.72; 95%CI = 1.55-7.16; P = 0.02), and the -163A carriers were at increased risk of bladder cancer in a multivariate COX regression model (OR = 4.89, 95%CI = 2.78-10.87, P = 0.01). We conclude that the CYP1A2-163C/A polymorphism is associated with increased susceptibility to bladder cancer in the Chinese population.

Abstract
Context Understanding habitat use and selection by threatened ungulates is a crucial prerequisite to prioritise management areas and for developing effective conservation strategies. Aims The aim of our research was to determine the habitat use and selection of takins (Budorcas taxicolor) in the middle range of the Qinling Mountains, China. Methods The study was conducted from August 2013 to August 2015. Global positioning system (GPS) radio-tracking was used to monitor 10 collared takins to gain their location information. The Manly–Chesson selectivity index and Bonferroni-adjusted 95% confidence intervals were applied to determine which habitats were selected. Key results Habitat use and selection by takins showed obvious individual differences. At the landscape scale, all of the four most common habitat types were preferred by takins. However, all takins avoided artificially planted larch forest, and farmland and village. Available habitats within the home ranges also mostly included the four common habitat types. At the home-range scale, all individuals had significant habitat selectivity during the entire tracking period and each season. The habitat use and selection within the home range varied obviously with season and showed sexual differences to a certain extent. Conclusions The habitat selection by takins is scale-dependent. At the landscape scale, takins are most likely to occur at sites covered by forest. At both landscape and home-range scales, our results indicated that takins need more diverse forest habitats, but none of the four most common forest habitats is essential for survival of this species. Implications The present work has provided more insight into the habitat use and habitat selection of takins in mountainous forest landscapes. Many measures such as maintaining a diversity of forest habitats, avoiding habitat alteration by invasion of exotic plants, and increasing the area of available habitats by relocating the villages from within to outside of the reserve are recommended to conserve this large species.

Abstract
Although a number of studies have shown that chemical hybridizing agents (CHAs) affect anther growth and regulate cell-cycle progression, little is known about the molecular and cellular mechanisms involved. Proliferating cell nuclear antigen (PCNA) is an essential factor in DNA replication, and in many other processes in eukaryotic cells. In this study, the open reading frame of TaPCNA, the PCNA in wheat (Triticum aestivum L.), was cloned by reverse transcription polymerase chain reaction (RT-PCR). Sequence analysis revealed that this gene was 792-bp long and encoded a protein with 234 amino acids. Alignment of the TaPCNA-predicted sequence revealed a high degree of identity with PCNAs from other plant species. A subcellular localization assay indicated that TaPCNA was localized in the nucleus. The TaPCNA was cloned into the prokaryotic expression plasmid pET32a, and the recombinant plasmid was transformed into BL21 (DE3). TaPCNA expression was induced by 0.5 mM isopropyl-beta-D-thiogalactopyranoside and verified using sodium dodecyl sulfate polyacrylamide gel electrophoresis and western blot assays, which indicated that the fusion protein was successfully expressed. The gene involved in the G1-to-S transition, Histone H4, was downregulated by 1376- CIMS, which is a chemically induced male sterility line. However, a semi-quantitative RT-PCR revealed that TaPCNA expression was upregulated in 1376-CIMS. Our results suggest that CHAs (SQ-1) induce DNA damage in wheat anthers. DNA damage results in either the delay or arrest of cell-cycle progression, which affects anther development. This study will help to elucidate the mechanisms of SQ-1-induced male sterility.

Abstract
In this work, bovine serum albumin (BSA) and eosine B (EB) were selected as a model protein and sonosensitizer, respectively. The sonodynamic damage to protein in the presence of EB and its mechanism were studied by means of absorption and fluorescence spectra. The results indicated that the synergistic effects of ultrasound and EB can efficiently damage the BSA molecules, and the damage of protein could be mainly due to the generation of reactive oxygen species (ROS). The damage degree of protein increased with the increase of ultrasonic time and EB concentration because of the increased quantities of ROS. Hydroxyl free radical (OH) was the major mediators of the ultrasound-inducing proteins damage in the presence of EB. In addition, the quantities of ROS from the diphenylcarbazide (DPCI)-EB solutions and the DPCI-fluorescein (FS) solutions with or without ROS scavengers were contrasted, respectively. The results show that FS mainly produce OH, but the quantities of ROS in the presence of FS were lower than those of EB, which indicates that the nitro and bromine substituent groups on the benzene ring of FS increase the quantity of ROS, but do not change the kinds of ROS.

Abstract
Wheat (Triticum aestivum L.), the most widely grown winter cereal crop in China, was grown on 24.3 million hectares in 2012. There was an outbreak of Fusarium head blight in 2012, and it was prevalent in 2013 in North China Plain, the largest area producing winter wheat in China. In 2013, a total of 213 Fusarium graminearum-like isolates were collected from diseased wheat heads in 33 fields in 17 counties in Henan province. The pathogen was isolated from the base of Fusarium-damaged spikelets on potato dextrose agar (PDA) after being surface-sterilized (70% EtOH for 30 s and 3% NaClO for 1.5 min) and rinsed three times in sterilized distilled water. After 3 days, the mycelia were transferred to fresh PDA and purified by the single-spore isolation method. Species were identified based on morphological characteristics (2), and sequence analysis of the translation elongation factor-1α (TEF) and trichothecene 3-O-acetyltransferase (Tri 101) gene (3). The results indicated that F. graminearum species complex (97.2%) is the main causal agent of Fusarium head blight in this region. However, four strains (2%) from the two fields in Jiao Zuo and Xin Xiang counties were found to be identical to F. pseudograminearum. The four (13JZ3-1, 13JZ3-2, 13XX1-2, and 13XX1-6) isolates of F. pseudograminearum were transferred onto carnation leaf agar (CLA) and incubated at 20°C under black light blue illumination. On CLA, macroconidia were abundant, relatively slender, curved to almost straight, commonly six- to seven-septate, and averaged 49.7 × 5.0 μm. Microconidia were not observed. Chlamydospores were observed after 4 weeks. The fungus was initially identified as F. graminearum on the basis of morphology of the asexual stage (2). However, the TEF sequences (Accession nos. KJ863322 to KJ863325) showed 99 to 100% similarity with several F. pseudograminearum sequences (e.g., AF212468, AF212469, and AF212470); the Tri 101 sequences (KJ863326 to KJ863329) showed 99 to 100% similarity with accession nos. AF212615 and AF212616 of F. pseudograminearum. The identification was further confirmed by the F. pseudograminearum species-specific PCR primers (Fp1-1: CGGGGTAGTTTCACATTTCCG and Fp1-2: GAGAATGTGATGACGACAATA) (1). To complete Koch's postulates, the pathogenicity of the fungus was tested by spraying five healthy inflorescences (average of 19 spikelets per spike) of wheat cultivar Zhoumai 18 with a 5-ml suspension (5 × 104 conidia per milliliter). Another five healthy inflorescences were sprayed with sterile distilled water. Plants were placed in a growth chamber with a 12-h photoperiod at 22°C, covered with polyethylene bags that were removed after 2 days. Seven days later, while control inflorescences were asymptomatic, inoculated inflorescences showed a mean of 10 bleached spikelets per spike. By using the methodology described above, the fungus was re-isolated from infected spikelets of inoculated wheat heads but not from the controls. To our knowledge, this is the first report of F. pseudograminearum from diseased wheat heads in China. Further investigation is needed to gain a better understanding of the spatial and temporal dynamics of this new pathogen. References: (1) T. Aoki and K. O'Donnell. Mycologia 91:597, 1999. (2) J. F.

Abstract
An emerging issue in wildlife conservation is the re-establishment of viable populations of endangered species in suitable habitats. Here, we studied habitat selection by a population of Hainan Eld's deer (Cervus eldi) relocated to a patchy landscape of farmland and forest. Hainan Eld's deer were pushed to the brink of extinction in the 1970s, but their population expanded rapidly from 26 to more than 1000 individuals by 2003 through effective reserve protection. As part of a wider relocation and population management strategy, 131 deer were removed from the reserve and reintroduced into a farmland-forest landscape in 2005. Habitat use under a context of human disturbance was surveyed by monitoring 19 radio-collared animals. The majority of deer locations (77%) were within 0.6-2 km of villages. Annual home ranges of these collared deer averaged 725 ha (SD 436), which was 55% of the size of the reserve from which they had originated. The annual home ranges contained 54% shrub-grassland, 26% forest and 15% farmland. The relocated deer population selected landscape comprising slash-and-burn agriculture and forest, and avoided both intensively farmed areas and areas containing only forest. Within the selected landscape, deer preferred swiddens and shrub-grasslands. Forests above 300 m in elevation were avoided, whereas forests below 300 m in elevation were overrepresented during the dry season and randomly used during the wet season. Our findings show that reintroduced deer can utilize disturbed habitats, and further demonstrate that subsistence agroforest ecosystems have the capacity to sustain endangered ungulates.

Abstract
Angular-type pyranocoumarins (APs), the derivatives of khellactone, are widely documented as the main active constituents in Peucedani Radix (Chinese name: Qian-hu). Owing to the natural occurrence of chiral centers, enantiomers of APs are extensively distributed in the original plant, and enantioselective performances have been definitely demonstrated for these enantiomers. In current study, the chemical characterization of the major and minor APs in Peucedani Radix was performed using ultra high performance liquid chromatography coupled with diode array detector and hybrid ion trap-orbitrap mass spectrometry. On the other hand, a heart-cut two-dimensional achiral-chiral liquid chromatography combining triple quadropole-linear ion trap mass spectrometry system (2D LC-MS/MS) was developed for simultaneous enantiospecific quantification of eighteen coumarins, including seven pairs of enantiomers. Eleven APs (1-11) were recruited to propose UV absorption characteristics and electrospray ionization fragmentation patterns of APs. A total of 42 components were categorized into APs based on their UV spectral properties and identified according to the proposed mass fragmentation pathways, while two linear-type furanocoumarins (12-13) were unambiguously assigned by further purification. A Capcell core RP-C18 column was employed in the primary LC dimension to achieve efficient racemic separation for the main chemical constituents (1-9 and 12-13) in Peucedani Radix, while a Chiralpak AD-RH column was utilized in the secondary dimension to contribute enantioselective separation for seven enantiomerically enriched components (1, 3 and 5-9). Collectively, the results provided the chemical evidences for revealing the material basis of the therapeutic effects of Peucedani Radix, and the developed 2D LC-MS/MS system in the present study is expected to be an ideal tool for the quality control of Peucedani Radix as well as a reliable technique for complex matrices containing both achiral and chiral components.

Abstract
Aquaporin-1 (AQP1) is the principle water channel in the peripheral nervous system (PNS) and is specifically localized to Schwann cells in the PNS. However, the pathophysiological role of AQP1 in peripheral nerves is poorly understood. Here, we utilized RNA interference by lentiviral transduction to specifically down-regulate AQP1 expression and a lentiviral overexpression protocol to up-regulate AQP1 expression, in primary Schwann cell cultures. AQP1 gene silencing resulted in a cell shrinkage phenotype, while AQP1 gene overexpression caused a cell swelling phenotype, as validated by cell volume determinations. Secondly, we utilized an in vitro hypoxia model in Schwann cells to mimic in vivo facial nerve injury. We demonstrated that AQP1 expression was induced within 8h following hypoxia injury in vitro, and that AQP1 knockdown (KD) caused the cells to resist edema following hypoxia. Finally, we investigated the hypoxic regulation of the AQP1 gene, as well as the involvement of Hypoxia-inducible factor-1α (HIF-1α) in AQP1 modulation and we found that KD of HIF-1α decreased hypoxia-dependent induction of endogenous AQP1 expression at both the mRNA and protein levels. Taken together, these results indicate that (1) AQP1 is an important factor responsible for the fast water transport of cultured Schwann cells and is involved in cell plasticity; (2) AQP1 alterations may be a primary factor in hypoxia-induced peripheral nerve edema; (3) HIF-1α participates in the hypoxic induction of the AQP1 gene; (4) AQP1 inhibition might provide a new therapeutic alternative for the treatment of some forms of peripheral nerve edema.
