Abstract
The aim of this study was to investigate the treatment effects of a stabilisation splint (SS) with and without arthroscopic disc repositioning (ADR) on condylar bone remodelling in adolescent patients with anterior disc displacement without reduction (ADDwoR). Cone beam computed tomography and magnetic resonance imaging were used to analyse condylar bone remodelling, condyle position, and disc position. Twenty-two temporomandibular joints of 14 patients who underwent ADR (age range 12-20 years; mean follow-up 12.5 ± 7.8 months) and 21 temporomandibular joints of 14 patients who did not undergo ADR (age range 13-20 years; mean follow-up 11.1 ± 5.1 months) were included. The change in bone volume (P < 0.001), rate of bone volume change (P < 0.001), and change in condyle height (P = 0.031) were significantly greater in patients with ADR than in those without ADR. The changes in posterior joint space (P = 0.013), superior joint space (P = 0.020), and ratio of condyle sagittal position (P = 0.013) were significantly greater in patients with ADR than in those without ADR. All discs in patients who underwent ADR and one disc in those who did not undergo ADR were backward repositioned. In conclusion, in adolescent patients with ADDwoR, ADR with SS therapy achieved better condyle and disc position than SS therapy alone, and also induced bone generation.

Abstract
Objective: To evaluate the association between digestive tract cancer and anatomical severity of coronary artery disease. Methods: This study enrolled 142 patients with digestive tract cancer who underwent coronary angiography in the Department of Cardiology of the First Medical Center of Chinese PLA General Hospital from 2009 to 2020 as the cancer group. The patients in cancer group were matched with 426 non-cancer patients who underwent coronary angiography at our hospital during the same period in a 1∶3 ratio based on gender and age. All enrolled patients had no previous history of percutaneous coronary intervention or coronary artery bypass grafting surgery. The severity of coronary artery disease was documented and assessed using the SYNTAX score based on angiogram. High SYNTAX score (SXhigh) was defined as SYNTAX score≥22 (upper quartile), while low SYNTAX score (SXlow) was SYNTAX score<22. High NLR (NLRhigh) was NLR≥2.287 (median), while low NLR (NLRlow) was NLR<2.287. The association between digestive tract cancer and severity of coronary artery disease was analyzed using logistic regression analysis. Results: This study included a total of 568 patients, with a mean age of (66.6±8.7) years. Among them, 430 patients (75.7%) were male. The cancer group consisted of 142 patients with digestive tract cancers, with a mean age of (66.5±8.4) years. The non-cancer group consisted of 426 patients, with a mean age of (66.7±8.8) years. The proportion of SXhigh in patients with digestive tract cancers (33.1%, 47 patients) was higher than that in non-cancer patients (23.9%, 102 patients) (P=0.032). Compared to non-cancer patients, SXhigh in patients with digestive tract cancers was higher (OR: 1.614, 95%CI: 1.051-2.481, P=0.029). Subgroup analysis stratified by NLR levels revealed that in the NLRhigh group, patients with digestive tract cancers exhibited a higher severity of coronary artery disease compared to non-cancer patients, with an OR of 1.948 (95%CI: 1.005-3.779, P=0.048). In the NLRlow group, there was no significant relationship between digestive tract cancers and the severity of coronary artery disease, with an OR of 1.277 (95%CI: 0.586-2.781, P=0.538). Conclusions: Digestive tract cancer is associated with the severity of coronary artery disease, and patients with digestive tract cancers have a higher risk of severe coronary artery disease than non-cancer patients. Additionally, there is an association between digestive tract cancers and the severity of coronary artery disease under conditions of high levels of inflammation.

Abstract
MicroTom has a short growth cycle and high transformation efficiency, and is a prospective model plant for studying organ development, metabolism, and plant-microbe interactions. Here, with a newly assembled reference genome for this tomato cultivar and abundant RNA-seq data derived from tissues of different organs/developmental stages/treatments, we constructed multiple gene co-expression networks, which will provide valuable clues for the identification of important genes involved in diverse regulatory pathways during plant growth, e.g. arbuscular mycorrhizal symbiosis and fruit development. Additionally, non-coding RNAs, including miRNAs, lncRNAs, and circRNAs were also identified, together with their potential targets. Interacting networks between different types of non-coding RNAs (miRNA-lncRNA), and non-coding RNAs and genes (miRNA-mRNA and lncRNA-mRNA) were constructed as well. Our results and data will provide valuable information for the study of organ differentiation and development of this important fruit. Lastly, we established a database (http://eplant.njau.edu.cn/microTomBase/) with genomic and transcriptomic data, as well as details of gene co-expression and interacting networks on MicroTom, and this database should be of great value to those who want to adopt MicroTom as a model plant for research.

Abstract
Objective: To evaluate the efficacy of decitabine combined with low dose chemotherapy (LDC) in the treatment of high-risk, refractory and relapsed pediatric acute myeloid leukemia (AML). Methods: Clinical data of 19 AML children treated with decitabine combined with LDC in the Department of Hematology, Children's Hospital of Soochow University from April 2017 to November 2019 were analyzed retrospectively. The therapeutic response, adverse effects and survival status were analyzed,and the outcomes of patients were followed up. Results: Among 19 AML cases, there were 10 males and 9 females. Five cases were high-risk AML, 7 cases were refractory AML, and 7 cases were relapsed AML. After one course of decitabine+LDC treatment, 15 cases achieved complete remission, 3 cases got partial remission, and only 1 case didn't get remission. All patients received allogeneic hematopoietic stem cell transplantation as consolidation therapy. The follow-up time of all cases was 46 (37, 58) months, 14 children had survived. The cumulative three-year overall survival rate was (79±9) %, events free survival rates was (68±11) %, and recurrence free survival rate was (81±10) %. The most common adverse effects related to the induction treatment were cytopenia (19 cases) and infection (16 cases).There were no treatment-related death during the therapy. Conclusion: Decitabine combined with LDC is a safe and effective option for high-risk, refractory and relapsed AML children, which provides an opportunity for HSCT.

Abstract
Saururus chinensis, an herbaceous magnoliid without perianth, represents a clade of early-diverging angiosperms that have gone through woodiness-herbaceousness transition and pollination obstacles: the characteristic white leaves underneath inflorescence during flowering time are considered a substitute for perianth to attract insect pollinators. Here, using the newly sequenced S. chinensis genome, we revisited the phylogenetic position of magnoliids within mesangiosperms, and recovered a sister relationship for magnoliids and Chloranthales. By considering differentially expressed genes, we identified candidate genes that are involved in the morphogenesis of the white leaves in S. chinensis. Among those genes, we verified - in a transgenic experiment with Arabidopsis - that increasing the expression of the "pseudo-etiolation in light" gene (ScPEL) can inhibit the biosynthesis of chlorophyll. ScPEL is thus likely responsible for the switches between green and white leaves, suggesting that changes in gene expression may underlie the evolution of pollination strategies. Despite being an herbaceous plant, S. chinensis still has vascular cambium and maintains the potential for secondary growth as a woody plant, because the necessary machinery, i.e., the entire gene set involved in lignin biosynthesis, is well preserved. However, similar expression levels of two key genes (CCR and CAD) between the stem and other tissues in the lignin biosynthesis pathway are possibly associated with the herbaceous nature of S. chinensis. In conclusion, the S. chinensis genome provides valuable insights into the adaptive evolution of pollination in Saururaceae and reveals a possible mechanism for the evolution of herbaceousness in magnoliids.

Abstract
Objective: We aim to evaluate the morbidity and mortality of cancer attributable to human papillomavirus (HPV) infection in China in 2016. Methods: Based on the cancer incidence and mortality rates, national population data, and population attributable fraction (PAF) in China, we calculated the number of incidence and death cases attributed to HPV infection in different areas, age groups, and gender in China in 2016. The standardized incidence and mortality rates for cancer attributed to HPV infection were calculated by using Segi's population. Results: In 2016, a total of 124 772 new cancer cases (6.32 per 100 000) were attributed to HPV infection in China, including 117 118 cases in women and 7 654 cases in men. Of these cancers, cervical cancer was the most common one, followed by anal cancer, oropharyngeal cancer, penile cancer, vaginal cancer, laryngeal cancer, oral cancer, and vulvar cancer. A total of 41 282 (2.03 per 100 000) deaths were attributed to HPV infection, of which 37 417 occurred in women and 3 865 in men. Most deaths were caused by cervical cancer, followed by anal cancer, oropharyngeal cancer, penile cancer, laryngeal cancer, vaginal cancer, oral cancer, and vulvar cancer. The incidence and mortality rates of cervical cancer increased rapidly with age, peaked in age group 50-54 years, then decreased obviously. The morbidity and mortality rates of non-cervical cancer increased with age. The cancer case and death numbers in rural areas (57 089 cases and 19 485 deaths) were lower than those in urban areas (67 683 cases and 21 797 deaths). However, the age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of cervical cancer were higher in rural areas than in urban areas. There were no significant differences in ASIR and ASMR of non-cervical cancers between urban areas and rural areas. Conclusions: The incidence of cancers attributed to HPV infection in China was lower than the global average, but the number of incidences accounted largely, furthermore there is an increasing trend of morbidity and mortality. The preventions and controls of cervical cancer and male anal cancer are essential to contain the increases in cancer cases and deaths attributed to HPV infection.

Abstract
Hibiscus hamabo is a semi-mangrove species with strong tolerance to salt and waterlogging stress. However, the molecular basis and mechanisms that underlie this strong adaptability to harsh environments remain poorly understood. Here, we assembled a high-quality, chromosome-level genome of this semi-mangrove plant and analyzed its transcriptome under different stress treatments to reveal regulatory responses and mechanisms. Our analyses suggested that H. hamabo has undergone two recent successive polyploidy events, a whole-genome duplication followed by a whole-genome triplication, resulting in an unusually large gene number (107 309 genes). Comparison of the H. hamabo genome with that of its close relative Hibiscus cannabinus, which has not experienced a recent WGT, indicated that genes associated with high stress resistance have been preferentially preserved in the H. hamabo genome, suggesting an underlying association between polyploidy and stronger stress resistance. Transcriptomic data indicated that genes in the roots and leaves responded differently to stress. In roots, genes that regulate ion channels involved in biosynthetic and metabolic processes responded quickly to adjust the ion concentration and provide metabolic products to protect root cells, whereas no such rapid response was observed from genes in leaves. Using co-expression networks, potential stress resistance genes were identified for use in future functional investigations. The genome sequence, along with several transcriptome datasets, provide insights into genome evolution and the mechanism of salt and waterlogging tolerance in H. hamabo, suggesting the importance of polyploidization for environmental adaptation.

Abstract
Objective: To evaluate the performance of point-of-care testing for cervical cancer and precancerous lesions screening. Methods: In September 2020, 197 and 273 women were selected by using simple random sampling method from "self-sampling" cohort and "physician-sampling" cohort established in Xiangyuan county, Shanxi Province, China, respectively. Cervical exfoliated cells were collected by women themselves or gynecologists. All samples were detected by POCT and women with positive result were directly referred for colposcopy. Subsequently, all the samples were detected by careHPV and PCR test. Colposcopy and punch biopsy were performed for women with POCT negative but careHPV or PCR test positive at another visit. Using histopathological diagnosis as the gold standard, we calculated sensitivity, specificity and drew the receiver operating characteristic (ROC) curves. The accuracy of POCT was analyzed and compared to that of careHPV and conventional PCR test in cervical cancer and precancerous lesions screening. Results: The median (Q1 , Q3) age of 470 women was 51 (45, 57) years old. Based on self-sampling, the sensitivity and specificity of POCT for CIN2+ were 100.00% (95%CI: 56.56%-100.00%) and 28.95% (95%CI: 22.97%-35.76%), respectively. Compared with POCT, POCT HPV16/18 test had similar sensitivity and higher specificity of 89.47% (95%CI: 84.30%-93.08%). Self-sampling POCT HPV16/18 test had an AUC of 0.947 (95%CI:0.910-0.985), which was higher than that of careHPV and PCR test. Physician-sampling POCT test had 100.00% sensitivity (95%CI: 64.57%-100.00%) and 55.85% specificity (95%CI: 49.83%-61.70%) for detecting CIN2+. POCT HPV16/18 test had lower sensitivity (71.43%, 95%CI: 35.90%-91.76%) and higher specificity (92.45%, 95%CI: 88.63%-95.06%). POCT HPV16/18 test generally showed similar AUC on both self-collected samples and clinician-collected samples (0.947 vs 0.819, P=0.217). Conclusion: POCT HPV16/18 test is an effective method with relatively high sensitivity and specificity for cervical cancer screening.

Abstract
Plant and fruit surfaces are covered with cuticle wax and provide a protective barrier against biotic and abiotic stresses. Cuticle wax consists of very-long-chain fatty acids (VLCFAs) and their derivatives. β-Ketoacyl-CoA synthase (KCS) is a key enzyme in the synthesis of VLCFAs and provides a precursor for the synthesis of cuticle wax, but the KCS gene family was yet to be reported in the passion fruit (Passiflora edulis). In this study, thirty-two KCS genes were identified in the passion fruit genome and phylogenetically grouped as KCS1-like, FAE1-like, FDH-like, and CER6-like. Furthermore, thirty-one PeKCS genes were positioned on seven chromosomes, while one PeKCS was localized to the unassembled genomic scaffold. The cis-element analysis provides insight into the possible role of PeKCS genes in phytohormones and stress responses. Syntenic analysis revealed that gene duplication played a crucial role in the expansion of the PeKCS gene family and underwent a strong purifying selection. All PeKCS proteins shared similar 3D structures, and a protein-protein interaction network was predicted with known Arabidopsis proteins. There were twenty putative ped-miRNAs which were also predicted that belong to nine families targeting thirteen PeKCS genes. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) annotation results were highly associated with fatty acid synthase and elongase activity, lipid metabolism, stress responses, and plant-pathogen interaction. The highly enriched transcription factors (TFs) including ERF, MYB, Dof, C2H2, TCP, LBD, NAC, and bHLH were predicted in PeKCS genes. qRT-PCR expression analysis revealed that most PeKCS genes were highly upregulated in leaves including PeKCS2, PeKCS4, PeKCS8, PeKCS13, and PeKCS9 but not in stem and roots tissues under drought stress conditions compared with controls. Notably, most PeKCS genes were upregulated at 9th dpi under Fusarium kyushuense biotic stress condition compared to controls. This study provides a basis for further understanding the functions of KCS genes, improving wax and VLCFA biosynthesis, and improvement of passion fruit resistance.

Abstract
Cervical cancer can be eliminated through primary, secondary, and tertiary prevention. Yet it remains one of the gravest threats to women's lives worldwide. In November 2020, WHO officially launched the global strategy to accelerate the elimination of cervical cancer, and underlined that screening and treatment for cervical pre-cancer lesions are two of three key measures for the elimination. In July 2021, the World Health Organization (WHO) issued the second edition of"WHO guideline for screening and treatment of cervical pre-cancer lesions for cervical cancer prevention"to provide important guidance to countries to support them in achieving the target of cervical cancer elimination in all women. This article will interpret the methods for the guideline development, the recommendations/good practice statements on screening and treatment to prevent cervical cancer (including the age to start/stop screening, screening methods, screening interval, the management of screen-positive women and treatment of the precancerous lesions, etc.) and its impact globally, providing reference for the updates of guideline and policy making on cervical cancer prevention and control in China.

Abstract
BACKGROUND AND OBJECTIVE Brain tumors are among the most deadly cancers worldwide. Due to the development of deep convolutional neural networks, many brain tumor segmentation methods help clinicians diagnose and operate. However, most of these methods insufficiently use multi-scale features, reducing their ability to extract brain tumors' features and details. To assist clinicians in the accurate automatic segmentation of brain tumors, we built a new deep learning network to make full use of multi-scale features for improving the performance of brain tumor segmentation. METHODS We propose a novel cross-level connected U-shaped network (CLCU-Net) to connect different scales' features for fully utilizing multi-scale features. Besides, we propose a generic attention module (Segmented Attention Module, SAM) on the connections of different scale features for selectively aggregating features, which provides a more efficient connection of different scale features. Moreover, we employ deep supervision and spatial pyramid pooling (SSP) to improve the method's performance further. RESULTS We evaluated our method on the BRATS 2018 dataset by five indexes and achieved excellent performance with a Dice Score of 88.5%, a Precision of 91.98%, a Recall of 85.62%, a Params of 36.34M and Inference Time of 8.89ms for the whole tumor, which outperformed six state-of-the-art methods. Moreover, the performed analysis of different attention modules' heatmaps proved that the attention module proposed in this study was more suitable for segmentation tasks than the other existing popular attention modules. CONCLUSION Both the qualitative and quantitative experimental results indicate that our cross-level connected U-shaped network with selective feature aggregation attention module can achieve accurate brain tumor segmentation and is considered quite instrumental in clinical practice implementation.

Abstract
Objective: To systematically summarize the development of global human papillomavirus (HPV) vaccination guidelines. Methods: The retrieval for all the Chinese and English literature published before August 2020 was conducted in PubMed, Embase and China Biomedical Literature Database, with "papillomavirus vaccines" "wart virus vaccine" "guideline" "practice guideline" "health planning guidelines" "guidelines as topic" "practice guidelines as topic" "immunization programs" in English as well as "papillomavirus vaccines" "HPV vaccine" "guideline" "recommendation" "consensus" in Chinese as search keywords. A total of 18 guidelines were included for data extraction and analysis. Results: The 18 pieces of guidelines included 1 pieces of World Health Organization (WHO) position paper, 6 pieces of guidelines at national or provincial level and other 11 pieces of by academic institutions. In national or provincial guidelines, the recommendation for routine vaccination mainly focused on 11-13 year-old adolescents and the recommendation for catch-up vaccination extends to 17-26 years old. Recommendation of guidelines by academic institutions were similar to the WHO position paper: girls aged 9-14 as the primary target for the routine vaccination; females aged 15-26 years old as the secondary target populations when it's feasible, affordable and cost-effective; women aged over 26 could be vaccinated at an individual level. There were only three guidelines simultaneously updated with the national immunization programme and covered four aspects: the vaccinated population (girls-only to gender-neutral vaccination), the periodic catch-up immunization, the dose schedule updates and the change of vaccine types. Conclusions: It's recommended that the development of Chinese HPV vaccination guidelines refer to global guidelines and updates and take full consideration of the epidemiological evidence, resources and current status of the immunization system in China.

Abstract
Objective: To evaluate the effectiveness of thermal ablation in the treatment of human papillomavirus (HPV) infection and cervical intraepithelial neoplasia (CIN) in Chinese women. Methods: The high-risk HPV-positive women aged 20-65 who were detected through a cervical cancer screening project implemented in three rural sites (Etuoke counties in Inner Mongolia, Xiangyuan and Yangcheng counties in Shanxi Province) and one urban site (Shenzhen) in China were included in this prospective study. Follow up evaluation was performed on HPV positive women who underwent thermal ablation (n=166) as well as received no treatment (n=2 716) in cervical cancer screening program. For women with thermal ablation treatment, HPV test and cytology were used for follow-up with the interval of 6 months or longer after treatment. For women without treatment, HPV test was used for annual follow-up. Women with positive results in either of the HPV tests or abnormal cytology were referred for a colposcopy or biopsy if necessary. The HPV clearance rate and the cure rate of CIN were compared between the two groups. Results: A total of 152 women treated with thermal ablation and 2 539 women without treatment reported for follow-up evaluation with the age M(Q1, Q3) of 42 (36, 48) and 47 (41, 54) years old, and the median time to follow-up time of 23.4 (12.4, 24.5) and 23.5 (12.4, 24.0)months, respectively. The HPV clearance rate in women undergoing thermal ablation was significantly higher than that in women with no treatment (73.0% vs 46.1%, P<0.001). The HPV16, HPV52 and HPV58 clearance rates among women receiving thermal ablation were higher than that in women without treatment with the OR (95%CI) of 2.8 (1.3-6.1), 3.2 (1.3-7.9) and 5.8 (2.1-15.6). For women with histologically confirmed CIN at baseline, cure rates were 77.4%(n=72) for thermal ablation. Cure rates of the thermal ablation were 81.0%(n=47) for CIN grade one (CIN1) and 71.4% (n=25) for CIN grade two or worse (CIN2+). Conclusions: Thermal ablation is effective to clear the HPV infection as well as to treat CIN. Particularly for the HPV genotypes with the paramount attributable proportion to cervical cancer and precancerous in China, the HPV clearance rate was significantly higher than that reported in the women without treatment.

Abstract
Objective: To develop a fast track transfer to intensive care unit (ICU) for the perioperative high-risk elderly patients after hip fracture surgery and analyze the preliminary clinical effect of the application. Methods: From January 2014 to December 2017, before the application of postoperative fast track transfer to ICU, the clinical data of 195 elderly patients with hip fracture were included in a retrospective analysis. Among 195 hip fracture patients, 18 were transferred to ICU post operation (non-fast track group). Multivariate logistic regression analysis was applied to investigate relevant risk factors for transferring to ICU after hip fracture surgery. Based on risk factors acquired from the analysis and clinical experience, the fast track transfer to ICU for the perioperative high-risk elderly patients after hip fracture surgery was constructed according to the preliminary and experiential criteria. From January 2018 to December 2019, the clinical data of 70 patients (fast track group) who were transferred to ICU after hip fracture surgery through the fast track were collected and compared with non-fast track group. Results: Multivariate regression analysis revealed that American Society of Anesthesiologists classification(≥Ⅲ) (OR=4.260, 95%CI:1.157-15.683, P=0.029), pre-hospital stage (≥48 h) (OR=4.301, 95%CI:1.212-15.266, P=0.024), hemoglobin concentration at admission(<90 g/L) (OR=7.979, 95%CI:1.936-32.889, P=0.004), coronary heart disease as one comorbidity(OR=6.063, 95%CI:1.695-21.693, P=0.006) were independent risk factors for transferring to ICU after hip fracture surgery. There were no significant difference in gender, age, fracture type, hemoglobin concentration at admission and time of pre-hospital stage between the non-fast track group and fast track group(all P>0.05). However, the number of comorbidities in the fast track group was significantly higher than that in the non-fast track group (Z=-1.995, P=0.046). The time to surgery, postoperative hospital stay, and length of hospital stay in fast track group were all significantly less than those in non-fast track group (Z=-2.121, -2.726, -3.130, all P<0.05). Also, there were fewer medical consultations needed and fewer patients who stayed in ICU more than or equal to 2 nights in fast track group than that in non-fast track group(all P<0.05). There were no significant difference in the rate of patients who transferred from the general ward to ICU after transferring from ICU to the general ward, the proportion of patients who received more than or equal to 4 departments, operation time, hospitalization expense, mortality during hospitalization, 30-day mortality and 90-day mortality after operation between the two groups(all P>0.05). Conclusions: The fast track constructed in this study can reduce time to surgery, postoperative hospitalization stay and length of hospitalization stay for the perioperative high-risk elderly patients with hip fractures and is a specific clinical application of eras concept based on multidisciplinary team.

Abstract
Objective: To investigate the clinical feature, diagnosis, treatment and prognosis of childhood acute lymphoblastic leukemia (ALL) complicated with candida tropicalis bloodstream infection (CTBI), so as to improve the understanding of this disease. Methods: The general information, clinical manifestation, auxiliary examination, treatment and outcome of 14 childhood ALL who were diagnosed with tropical candidemia between January 2015 and December 2018 in 6 hospitals were analyzed retrospectively. Clinical data of non invasive fungal disease (IFD) ALL (28 cases) and other IFD children (9 cases) admitted in the same period were collected as control group. Logistic regression model was used to analyze the risk factor of CTBI. Results: Among 14 cases, there were 7 males and 7 females, with the age ranged from 17 months to 13 years. All the cases had fever, 9 cases had digestive system symptoms and stool fungal culture were positive in 3 of them; 7 cases had respiratory system symptoms and sputum fungal culture was positive in 1 of them; 2 cases had central nervous system symptoms and 10 cases progressed into septic shock. All 14 cases had neutropenia and the neutropenia duration was 1 to 53 days. Among 14 cases, the C-reactive protein was>50 mg/L in 8 cases, in which the proportion was significantly higher than that in other invasive fungal disease(IFD) (8/14 vs. 1/9, P<0.05), meanwhile the 1, 3-β-D-glucan detection, galactomannan detection and pulmonary imaging were not remarkable in all 14 cases. The blood culture results of 14 cases were all candida tropicalis, among which 13 cases finished drug susceptibility tests, the isolates of all cases were sensitive to flucytosine and amphotericin B, and the isolates of 4 cases were sensitive to fluconazole, voriconazole and itraconazole. Among 14 cases, 1 case lost to follow-up after giving up treatment, 1 case died before antifungal therapy and the remaining 12 cases received antifungal therapy; 7 of the 14 cases died. Univariate analysis showed that between ALL with CTBI group (14 cases) and ALL without invasive fungal disease (IFD) group (28 cases), the differences in variables such as ALL not in remission (χ²=37.847, P<0.01), length of hospital stay>15 days (χ2=8.351, P=0.004), neutropenia (χ²=14.280, P<0.01), neutropenia duration>10 days (χ²=10.254, P=0.001), use of broad-spectrum antibiotics (χ²=13.888, P<0.01), skin and mucous membrane damage (χ²= 5.923, P=0.015) were statistically significant. Conclusions: In childhood ALL complicated with tropical candidemia, the drug resistance rate and mortality rate were high. For azole-resistant tropical candida, amphotericin B liposome or echinocandins(caspofungin) -fluorocytosine combined therapy was recommended to reduce treatment-related deaths.

Abstract
Objective: To understand the infection rate and genotype distribution of high risk-human papillomavirus (HR-HPV) and the detection rate of different grades of cervical lesions in Han and Mongolian women in China and provide evidence for the development of screening and vaccination strategies for the prevention and control of cervical cancer in different ethnic groups. Methods: In June 2017, a multicenter, population-based study for cervical cancer screening in low-resource settings in China was conducted in three rural areas: Xiangyuan and Yangcheng counties in Shanxi province, and Etuoke county in Inner Mongolia Autonomous Region. A total of 9 517 women aged 30-65 years were included in the study, and two cervical and vaginal secretion samples were collected from them for HPV and PCR-based HPV DNA tests. The positive samples in any of two tests were used for PCR-based HPV genotyping test by using Sansure-pioneered One-Step Fast Release technology. Women with positive results in any the HPV tests were referred for colposcopy and punch biopsy was given if cervical intraepithelial neoplasia lesion (low-grade lesion or worse) was suspected in colposcopy evaluation. Endocervical curettage was performed if women had an unsatisfactory colposcopy exam (the squamocolumnar junction was not completely visible). Pathological detection result was used as the golden standard of diagnosis. Results: HR-HPV infection rates in Han and Mongolian women were 21.83% (1 842/8 438) and 24.93% (269/1 079), respectively. There were statistical differences in HPV infection rates between the two ethnic groups (χ(2)=5.328, P=0.021). The detection rate of cervical intraepithelial neoplasia grade 1 in Mongolian women (2.83%) was higher than that in Han women (0.87%), and the difference was statistically significant (χ(2)=33.509, P<0.001). There were no significant differences in cervical intraepithelial neoplasia grade 2 or worse detection rate between the two ethnic groups [Mongolian woman: 1.04% (11/1 059), Han Woman: 0.95% (80/8 378), χ(2)=0.069, P=0.793]. Among Han and Mongolian women with cervical intraepithelial neoplasia grade 2 or worse, the three most common HR-HPV types were HPV16, HPV52 and HPV58. There was no significant difference for multiple infection rate between Han and Mongolian women (41.37% vs. 44.35%, χ(2)=0.764, P=0.382). Conclusions: The results show that HPV infection rate in Mongolian women was higher than that in Han women. Close attention should be paid to HPV16, 52 and 58 in the prevention and control of cervical cancer in Han and Mongolian women.

Abstract
Objective: To investigate the value of intravoxel incoherent motion diffusion weighted imaging (IVIM DWI) in evaluating microstructure changes in elderly white matter hyperintensities (WMH) patients and to analyze the correlation between IVIM parameters and severity grading and cognitive scores. Methods: Sixty-two WMH patients in Zhejiang Hospital were collected from December 2014 to March 2018 and underwent conventional magnetic resonance (MR) plain scan and diffusion weighted imaging with different b values. The age was 60-92(74±10) years with 37 males, 25 females. The severity of WMH was assessed by T(2) fluid attenuated inversion recovery (FLAIR) sequence and Fazekas score,which were divided into two subgroups. Slow diffusion coefficient (D), fast diffusion coefficient (D(*)) and perfusion fraction (f) from IVIM parameters of double exponential model were compared between regions of WMH (deep WMH (DWMH) and periventricular WMH (PWMH)) and surrounding normal white matter (NWM).The Shapiro-Wilk test was used for normality tests, Kruskal-Wallis tests and Dwass-Steel-Critchlow-Fligner (DSCF) procedure were used for the comparison among these parameters. Furthermore, Wilcoxon two-sample test was used for the comparisons between different severity. Pearson correlation analysis was performed to determine whether these D, D(*), f values were correlated with the mini mental state examination (MMSE) scores. Results: D(D)WMH (0.83(0.72,0.99)×10(-3) mm(2)/s), D(PWMH)((1.13±0.25)×10(-3) mm(2)/s) were significantly higher than D(NWM) ((0.71±0.05)×10(-3) mm(2)/s)(P<0.01). f (DWMH) ((8.94%(7.46%,11.67%)), f (PWMH)(8.34%(6.73%,9.96%)) were significantly higher than f (NWM)(6.71%±1.72%)(P<0.01).D in DWMH were significantly lower than that in PWMH(P<0.01), there's no statistically difference between other groups. D in severe WMH (both DWMH and PWMH) were significantly higher than that in mild WMH (P=0.000 1, P=0.04). Only f in PWMH were positively associated with the MMSE scores (r=0.326 5,P<0.05). Conclusions: IVIM DWI can noninvasively assess the variation of microstructure diffusion and perfusion in WMH in one sequence,which may objectively reflect the severity of these lesions. This method has important clinical significance for better assessment and management of this disease.

Abstract
Objective: To investigate the relationship between spontaneous miscarriage and embryonic chromosome abnormalities, and to evaluate the clinical application of karyotype analysis by chorionic villus cell culture. Methods: The chorionic villus karyotype of 1 983 cases of miscarriage from January 2010 to July 2016 in Guangzhou Women and Children's Mecical Center were analyzed retrospectively. The miscarried chorionic villi were obtained by curettage under sterilized condition. The chromosome specimens were prepared after chorionic villus cell culture. Karyotype analysis was performed by G-banding technique. Results: In the 1 983 samples, successful karyotype analysis was performed in 1 770 cases, with the successful rate of 89.98%. Chromosomal abnormalities were found in 1 038 cases (58.64%, 1 038/1 770). Chromosomal structural abnormalities were found in 37 cases. The numeral abnormalities were more common than structural abnormalities, and most of the numeral abnormalities were aneupoidies. In turn, they were trisomy 16, 45,X, trisomy 22, trisomy 2, trisomy 21, trisomy 15. The most common structural abnormality was balanced translocation, including Robersonian translocation. Female embryoes accounted for 61.02% (1 080/1 770) miscarriages and for 57.4%(596/1 770) of chromosomal abnormalities, while male embroyes acoounted for 61.02% (1 080/1 770) , 57.4% (596/1 770) respectively. The proportion of female embryoes was higher than male embryoes. The median age of the patients was 30 years old (16-46 years old) . As the maternal age increased, the proportion chromosomal abnormalities increased. The incidence of chromosomal abnormalities in the advanced age group (≥35 years) was 68.38% (240/351) , which was significantly higher than that in the younger group (56.24%, 798/1 419; χ(2)=17.10, P<0.01). Conclusions: Embryonic chromosomal abnormalities are the most common cause of early spontaneous miscarriage. The abnormalities centralize in some karyotypes. There is certain relationship between maternal age and the incidence of miscarriage, as well as the embryonic gender. Chorionic villus cell culture and karyotype analysis are helpful in finding the cause of miscarriage and counsel the patients.

Abstract
Objective: To analyze the epidemiological genotype features of human papillomavirus (HPV) in cervical infection and their risks for cervical precancers among women in Shenzhen area. Methods: A total of 2 717 individuals ranging in age from 30~59 years were recruited in 18 community health centers of Shenzhen city from March 1 to June 15, 2015 by a cluster sampling method. The results of genotype of HPV, liquid-based cytology (LBC), colposcopy and pathology were analyzed. The clinical sensitivity and specificity as well as positive (PPV) and negative (NPV) predictive values of the combination of different HPV genotype in screening the cervical intraepithelial neoplasia (CIN) 2 and above were estimated. Results: The HPV infection rate in Shenzhen area was 15.9% (432/2 717). The most common HPV genotype was HPV52 (22.9%), followed by HPV16 (12.7%), HPV53 (10.0%), HPV51 (8.6%) and HPV58 (8.1%). Compared with HPV16/18 genotyping, HPV33/16 genotyping had a higher sensitivity (57.1% vs. 42.9%, P<0.05) and an analogous specificity (87.3% vs. 86.9%, P>0.05) in predicting CIN2+ . The sensitivity of combination of HPV33/16 genotyping and low grade squamous intraepithelial lesion (LSIL) positive tested by LBC in predicting CIN2+ was 75.0%, significantly higher than 64.3% of atypical squamous cells of undetermined significance (ASC-US) positive tested by LBC alone (P<0.05). The specificities of these two methods mentioned above in predicting CIN2+ were 83.5% and 89.2%, respectively, without statistical difference (P>0.05). Conclusions: Women infected by HPV have distinct risks for CIN2+ according to different high-risk HPV genotypes. The top five risks were HPV 33, 16, 58, 56, and 68. HPV-positive women triaged by LBC LSIL+ combined with HPV33/16 genotyping may be a potential strategy for cervical cancer screening in developed urban area.

Abstract
The safety of decitabine as bridging treatment before allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children with refractory hematological malignancies was evaluated. All 11 cases succeeded in hematopoietic reconstitution. The main adverse reaction was hematological toxicity. Neither did infections occur, nor drug-induced liver damage and renal impairment during decitabine administration. Most cases showed grade Ⅰ-Ⅱgastrointestinal adverse events. One case was diagnosed as severe acute graft versus host disease and died of intracranial hemorrhage on day 61 after allo-HSCT. The other 10 patients survived. Decitabine bridge is a safe regimen before allo-HSCT in children with refractory hematological malignancies.

Abstract
Objective: To explore the role of HPV viral loads in random biopsy under normal colposcopy. Methods: 908 atypical squamous cells of undetermined significance (ASC-US) and HPV positive women, recruited in cluster sampling in 9 provinces including 5 urban areas and 9 rural areas in China from 1999 to 2008 and meeting the inclusion and exclusion criteria were included in this analysis. According to relative light units/cutoff (RLU/CO) value, subjects were stratified as low (286 cases), intermediate (311 cases) and high (311 cases) viral load groups. Risks of cervical intraepithelial neoplasia grade 3 or worse (CIN3+) among different viral load groups were compared with linear trend Chi-square test. Results: Detection rate of CIN3+ in low, intermediate and high viral load groups were 2.1% (6 cases), 2.6% (8 cases) and 6.8% (21 cases) (Chi-square test for trend χ(2)=8.91, P=0.003) and were 60.3, 74.0 and 201.3 times higher than ASC-US and HPV negative women, respectively. Among 908 subjects, 27.0% (245 cases) were abnormal under colposcopy and 68.6% (623 cases) diagnosed as normal. Under normal colposcopy, detection rate of CIN3+ in low, intermediate and high viral load groups were 0.9% (2 cases), 0.9% (2 cases) and 3.8% (7 cases) (χ(2)=6.42, P=0.040). Conclusion: HPV viral loads display satisfactory risk stratification ability among ASC-US and HPV positive women under normal colposcopy. Women with high HPV viral loads show a significantly increased detection rate of existing CIN3+ and could be recommended to perform random biopsy for histologic diagnosis.

Abstract
Objective: To analyze the distribution and associated factors of high-risk genotypes of HPV in cervical infection among women in Shenzhen. Methods: The information on sociodemographic characteristics and HPV genotypes of HPV-positive women who participated cervical screening test from January 2014 to December 2016 was downloaded from Shenzhen Maternity and Child Healthcare Management Information System. According to the pathogenicity, the high-risk HPV genotypes were divided into 15 types including HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66 and 68; and there were 6 low-risk genotypes including HPV 6, 11, 42, 43, 44, and 81. Chi-square tests were applied to compare the proportions of high-risk HPV infection among women who had different sociodemographic characteristics. A non-conditional logistic regression model was used to analyze the associated factors for high-risk HPV infection. Results: In total, all HIV positives received HPV genotyping, with an average age of (38.08±9.38) years old. There were 9 979 (93.9%) high-risk and 645 (6.1%) low-risk HPV infections. The proportions of HPV infections for high-risk type in each year were 91.5%, 93.8%, and 95.6%, increasing with the screening years (χ(2)=54.79, P<0.001). Multivariate logistic regression analysis showed that compared with women younger than 25 years old, women in other age groups (at age 26 to 30 years, 31 to 35 years, 36 to 40 years, 41 to 45 years, and 50 years or older) had increased risks of high-risk HPV infection, with OR (95%CI) of 1.67 (1.20-2.31), 1.49 (1.09-2.03), 1.71 (1.23-2.37), 1.65 (1.19-2.31), and 1.84 (1.26-2.67), respectively; compared with the married, single women had a decreased risk of high-risk HPV infection (OR (95%CI): 0.71 (0.50-1.00)); women received HPV testing in 2015 and 2016 showed higher risk of high-risk HPV infection than those in 2014 (OR (95%CI): 1.43 (1.17-1.74) and 2.03 (1.68-2.46)). The 5 most common HPV genotypes were HPV52 (25.1%, 2 670 cases), followed by HPV16 (19.2%, 2 041 cases), HPV58 (13.3%, 1 413 cases), HPV18 (9.9%, 1 048 cases), and HPV51 (9.3%, 993 cases). Conclusion: Age, marital status, and screening year were associated with high-risk HPV infections. Besides HPV16 and HPV18, the prevention and control on HPV infections for HPV52, HPV58, and HPV51 should be prioritized in Shenzhen area.

Abstract
Objective: To observe the growth and metastasis of lung cancer promoted by bone marrow derived mesenchymal stem cells (BMSCs) in tumor microenvironment and investigate the underlined mechanisms. Methods: Specific chemotaxis of BMSCs towards lung cancer was observed, and the tumor growth and metastasis were assessed in vivo. Furthermore, CD34 expression determined by immunohistochemistry was used to assess the microvessel density (MVD), and the expressions of GFP and α-SMA determined by immunofluorescence were used to detect the BMSCs derived mesenchymal cells. We investigated the effect of BMSCs on migration, invasion of lung cancer cells including A549 and H446 cells by using scratch assays and Transwell Assay in vitro. We also explored the effect of BMSCs on epithelial mesenchymal transition of A549 and H446 cells by observing the phenotype transition and E-Cadherin protein expression detected by Western blot. At last, we screened the potentially key soluble factors by enzyme linked immunosorbent assay (ELISA). Results: In NOD mice, labeled BMSCs injected via tail vein were special chemotaxis to tumor cells, and promoted the tumor growth [the time of tumor formation in A549+ BMSCs and A549 alone was (5.0±1.5) days and (10.0±3.6) days, respectively, P<0.05; the time of tumor formation in H446+ BMSCs and H446 alone was (5.2±1.5) days and (12.0±2.0) days, respectively, P<0.05]. The tumor incidence of A549+ BMSCs was 100%, significantly higher than 66.7% of A549 alone (P<0.05), while the tumor incidence of H446+ BMSCs was 83.0%, significantly higher than 50.0% of H446 alone (P<0.05). The BMSCs also increased the tumor volume [the tumor volume of A549+ BMSCs and A549 alone was (193.0±42.3) mm(3) and (97.8±42.9) mm(3,) respectively, P<0.05; the tumor volume of H446+ BMSCs and H446 alone was (78.6±34.8) mm(3) and (25.3±12.7) mm(3,) respectively, P<0.05] and facilitated the tumor metastasis (the tumor metastatic incidence of A549+ BMSCs and A549 alone was 100.0% and 16.7%, respectively, P<0.05; the tumor metastatic incidence of H446+ BMSCs and H446 alone was 100.0% and 0.0%, respectively, P<0.05). Furthermore, BMSCs increased tumor vessel formation (the MVD of A549+ BMSCs and A549 alone was 53.2±11.4 and 25.3±11.5, respectively, P<0.05; the MVD of H446+ BMSCs and H446 alone was 56.8±12.5 and 24.8±10.0, respectively, P<0.05). BMSCs were able to differentiate to fibroblasts in the lung squamous cell carcinoma and promoted the migration and invasion of lung cancer cells (the A of cells in the migrated lower chambers of A549+ BMSCs and A549 alone was 1.9±0.2 and 1.1±0.1, respectively, P<0.05; the A of cells in the migrated lower chambers of H446+ BMSCs and H446 alone was 1.9±0.3 and 0.9±0.2, respectively, P<0.05). The cell shape was longer and sharper, the intercellular junctions were reduced and the relative expression level of E-Cadherin protein in A549 co-cultured with BMDCs was 0.36, significantly down-regulated when compared to 0.55 of A549 alone (P<0.05), and the relative expression level of E-Cadherin protein in H446 co-cultured with BMDCs was 0.28, significantly down-regulated when compared to 0.46 of H446 cells alone (P<0.05). The concentration of IL-6 in the conditional medium of BMSCs, A549 co-cultured with BMSCs and H446 co-cultured with BMSCs was 910.5, 957.2, and 963.8, respectively, significantly up-regulated when compared to 18.8 of control group (P<0.05). The expression level of PGE2 in A549 co-cultured with BMSCs and H446 co-cultured with BMSCs was 130.5 and 87.2, significantly up-regulated when compared to 13.8 of control group and 23.8 of BMSCs group (P<0.05). Conclusions: Our results suggest that BMSCs contribute to the tumor growth through facilitating angiogenesis, and promote tumor metastasis through paracrine manner and down-regulation of E-Cadherin protein. IL-6 and PGE2 produced by BMDCs might be the potentially important cytokines.

Abstract
Objective: To evaluate the dynamic variation of genotypes distribution of human papillomavirus (HPV) over 10-year follow-up in a cervical cancer screening cohort. Methods: Based on the Shanxi Province Cervical Cancer Screening Study Ⅰ cohort, we detected HPV genotypes on the well-preserved exfoliated cervical cells from women who were tested HPV positive from year 2005 to year 2014 using reverse linear probe hybridization assay. The changes of prevalence of type-specific HPV over time among the overall population were estimated using linear mixed models. The association between the type-specific HPV and cervical intraepithelial neoplasia grade 2 or worse (CIN2 +) was calculated by linear Chi-square test. Finally, the trends of multiple infections of HPV with the increase of the age were analyzed. Results: During the cervical cancer screening of the overall population from 2005 to 2014, the most common genotypes among the population were HPV16 and 52. The prevalence of HPV16 decreased over time from 4.6% in 2005 to 2.2% in 2010 and 2014 (F=8.125, P<0.001). The prevalence of HPV52 remained pretty stable and HPV33, 51 and 58 slightly decreased then apparently increased. Further stratification analysis by pathological lesions showed the same trend of the HPV prevalence for the histology normal women with the overall population. Of note, for those women with the cervical intraepithelial neoplasia (CIN2 +), the detection rate of HPV16 decreased from 65.22% in 2005 to 41.03% in 2010 and finally to 31.58% in 2014 (χ(2)=4.420, P=0.036) and that of HPV33 substantially increased. No significant variation was found for other types of HPV. Multiple infection rate varied with the growing age of the women. Conclusions: The genotypes prevalence of HPV tended to vary over time during cervical cancer screening in the context of regular screening combining with immediate treatment for those CIN2 + women. HPV16 prevalence significantly decreased over time, which indicated that the variation of type-specific HPV prevalence should be considered when regular cervical cancer screening was organized using HPV technique.

Abstract
A previous study has revealed that miR-29c functions as a tumor suppressor in hepatocellular carcinoma (HCC), but the clinical significance and prognostic value of miR-29c in HCC have not been investigated. Paired human HCC tissues and adjacent noncancerous tissues were obtained from 91 patients, between 2008 to 2014. Quantitative real-time PCR (qRT-PCR) was used to analyze miR-29c expression. Kaplan-Meier survival plots and log-rank tests were used to assess differences in the overall survival of different subgroups of HCC patients. It was observed that miR-29c expression was remarkably decreased in HCC tissues relative to that in normal hepatic tissues (P < 0.001). The low miR-29c level was significantly associated with histologic grade (P = 0.001), microvascular invasion (P = 0.005), and tumor stage (P < 0.001). Kaplan-Meier analysis showed that decreased miR-29c expression correlated with shorter overall survival (P = 0.002). Multivariate Cox regression analysis showed that decreased miR-29c expression (hazard ratio = 2.19, 95%CI = 1.361-6.779, P = 0.025) was independently associated with poor survival in HCC. Our findings demonstrate that miR-29c expression is significantly downregulated in HCC patients and that miR-29c can act as an independent predictor of unfavorable clinical outcome.

Abstract
BACKGROUND Radiofrequency ablation (RFA) is currently the most widely used thermal ablative technique for unresectable hepatic malignancies. However, microwave ablation (MWA) is also gaining popularity worldwide. With a cooled-tip electrode, MWA produces necrotic effects comparable to RFA without damaging soft tissues along the electrode track. In this study, the authors compared the efficacy of these two ablative modalities in the treatment of primary or secondary liver cancer. MATERIALS AND METHODS Ultrasound-guided MWA was employed to treat 230 cases of liver cancer with a total of 349 nodules and a diameter of 0.8-11.4 cm [mean: 5.7 +/- 2.1 cm]. Meanwhile, ultrasound-guided RFA was performed in 92 cases of liver cancer with 173 nodules in total and a diameter of 2.0-10.2 cm [mean: 5.4 +/- 1.9 cm]. The clinical data were retrospectively analyzed to identify the differences between MWA and RFA in terms of their operative safety, local ablative effect, cost efficiency, and cumulative survival rate. RESULTS The patient parameters were comparable. The area of coagulative necrosis was similar in both groups. The tumor complete ablation rate was 83.7% (292/349) for the MWA group and 86.7% (150/173) for the RFA group, which showed no significant difference (P = 0.75). The one-year and two-year cumulative survival rate were all comparable between the two groups (P = 0.66, P = 0.41), which were 90.0% (198/220), 81.6% (120/147) for the MWA group, and 91.8% (78/85), 81.0% (34/42) for the RFA group, respectively. Moreover, both the tumor type and number had no influence on survival rate for the two methods. In addition, there was no significant difference in complication rates between the two groups. The cost for performing one MWA procedure was about 40% lower than that of RFA ($1200 vs $2000). CONCLUSIONS Both MWA and RFA are safe and effective ablative treatments for liver cancer. Additionally, MWA has the advantage of cost efficiency.

Abstract
AIMS/HYPOTHESIS Increasing evidence suggests that diabetes is associated with an enhanced risk of cognitive decline. The precise mechanisms underlying diabetes-associated cognitive decline (DACD) remain unclear. Here we investigated the molecular changes associated with DACD using a comparative proteomics study of hippocampus in a rat model of type 2 diabetes. In addition, we tested the effects of the Chinese medicine ZiBu PiYin recipe (ZBPYR) on DACD. METHODS The hippocampus was dissected from control, diabetic and diabetic rats treated with ZBPYR (DM/ZBPYR). Soluble proteins were separated using fluorescence-based difference gel electrophoresis. Protein spots were visualised with fluorescent dyes and spot density was compared between each pair of groups. Proteins of interest were identified using mass spectrometry. Proteins of specific interest were also tested by western blot and real-time PCR analysis. RESULTS We found 13 spots that were altered between control and diabetes groups, and 12 spots that were changed between diabetes and DM/ZBPYR groups. The identities of nine proteins were determined by mass spectrometry. The identified proteins were largely involved in energy metabolism, cytoskeleton regulation and oxidative stress. The protein alterations observed in the diabetes group were ameliorated to varying degrees following ZBPYR treatment. CONCLUSIONS/INTERPRETATION The protein changes identified in hippocampus from a rat model of type 2 diabetes suggest that specific cellular alterations contribute to DACD. The Chinese medicine ZBPYR was found to affect multiple targets and partially repaired the original cellular balance. This study may provide important insights into the molecular events underlying DACD and allow the identification of novel therapeutic targets.

Abstract
We estimate the accuracy of colposcopy and visual inspection with acetic acid (VIA) while minimizing the effects of misclassification bias, and maximizing ascertainment of disease. VIA was performed by experienced physicians on a population-based sample of women aged 30 to 49 years in rural Shanxi province, China. Each woman received VIA, liquid-based cytology (LBC) and hybrid capture 2 (hc2, QIAGEN, Gaithersburg, MD; formerly Digene Corporation). Any woman who tested positive on any test had colposcopy, endocervical curettage (ECC) with directed biopsies as necessary and 4-quadrant random biopsies from normal-appearing areas of the cervix. A standard diagnosis based on colposcopy and directed biopsy, and an expanded diagnosis including ECC and 4-quadrant random biopsy were generated for each woman. In 1,839 women, use of the expanded versus the standard diagnostic criteria increased the prevalence of histologically confirmed high-grade cervical intraepithelial neoplasia and cancer (CIN2+) from 3.2% (59/1,839) to 4.2% (77/1,839) and decreased the sensitivity of VIA for CIN2+ from 69.5% (95% CI: 56.8-79.8) to 58.4% (95% CI: 47.3-68.8%) with little change in specificity of approximately 89%. Compared with the expanded diagnostic criterion, the sensitivity of a visual diagnosis of high-grade CIN or cancer by a colposcopist was 49.4% (95% CI: 38.2-60.5). The use of an expanded diagnostic criterion in this study yielded more conservative estimates of the sensitivity of VIA and colposcopy.

Abstract
BACKGROUND In the past, previous operation of biliary tract represented a contraindication to perform reoperation by laparoscopy. As experience with laparoscopic techniques and instrumentation has expanded, reoperation of biliary tract with laparoscope has become an accepted procedure in the management of cholelithiasis. We present our interesting experience with regard to reoperation of biliary tract by laparoscopy. MATERIAL AND METHODS Laparoscopic operation of biliary tract was performed on 3,674 consecutive patients from April, 1992 till June, 2005. Among these patients, 26 had a previous open operation of biliary tract and their clinical data were retrospectively analyzed as follows: seven cases had complicated intrahepatic bile duct stones (restricted at hepatic duct of the first and second order). Diameter of common bile duct in patients with common duct stones was above 1.2 cm, the number of stones for each patient was more than 3 and all the biggest stones exceeded 1 cm. In the 26 patients, preoperatively, stenosis of bile duct and malignant tumour were excluded by both radiological examination and detection of serological tumour markers. RESULTS The mean operative time was 125 min (75-190 min). Reoperations of biliary tract by laparoscope were successfully accomplished in 25 patients. One patient was converted to open operation and the common duct stones were removed by right angle forceps through short incision. None of the patients developed any severe complication, all of them recovered and were successfully discharged. Three cases with retained calculuses were successfully cured by removing these through the sinus tract of T tube. CONCLUSIONS Laparoscopic procedure is minimally invasive, safe and feasible for laparoscopic experts in case of reoperation of biliary tract. It is also a first method for patients for whom endoscopic sphincterotomy is contraindicated.

Abstract
Tumor necrosis factor-alpha (TNF-a) is produced by alveolar macrophages (AM) in response to bleomycin (BLM) exposure. This cytokine has been linked to BLM-induced pulmonary inflammation, an early drug effect, and to lung fibrosis, the ultimate toxic effect of BLM. The present study was carried out to study the time dependence of apoptotic signaling pathways and the potential roles of TNF receptors in BLM-induced AM apoptosis. Male Sprague-Dawley rats were exposed to saline or BLM (1 mg/kg) by intratracheal instillation. At 1, 3, or 7 d postexposure, AM were isolated by bronchoalveolar (BAL) lavage and evaluated for apoptosis by ELISA. The release of cytochrome c from mitochrondria, the activation of caspase-3, -8, and -9, the cleavage of nuclear poly(ADP-ribose) polymerase (PARP), and the expression of TNF receptors (TNF-R1/p55 and TNF-R2/p75), TNF-R-associated factor 2 (TRAF2), and cellular inhibitor of apoptosis 1 (c-IAP1) were determined by immunoblotting. The results showed that BLM exposure induced AM apoptosis, with the highest apoptotic effect occurring at 1 d after exposure and gradually decreasing at 3 and 7 d postexposure, but still remaining significantly above the control level. The maximal translocation of cytochromec from mitochondria into the cytosol was observed at 1 d postexposure, whereas the activation of caspase-9 and caspase-3 and caspase-3-dependent cleavage of PARP was found to reach a peak level at 3 d postexposure. BLM exposure had no marked effect on AM expression of TNF-R1 or caspase-8 activation, but significantly increased the expression of TNF-R2 that was accompanied by a rise in c-IAP1 and a decrease in TRAF2. This induction of TNF-R2 by BLM was significant on d 1 and increased with greater exposure time. In vitro studies showed that pretreatment of naive AM with a TNF-R2 antibody significantly inhibited BLM-induced caspase-3 activity and apoptosis. These results suggest that BLM-induced apoptosis involves multiple pathways in a time-dependent manner. Since maximal BLM-induced AM apoptosis (1 d postexposure) preceded maximal changes in caspase-9 and -3 (3 d postexposure), it is possible that a caspase-independent mechanism is involved in this initial response. These results indicate that the sustained expression of TNF-R2 in AM by BLM exposure may sensitize these cells to TNF-a-mediated toxicity.

Abstract
Clinical presentation of aortic dissection is similar to that of acute myocardial infarction (AMI). Clinical differential diagnoses from lethal chest pain in emergency department include AMI, aortic dissection, pulmonary embolism, tension pneumothorax, etc. Thrombolytic therapy for recanalization of thrombotic occluded coronary artery in AMI must be considered, but it is absolutely contraindicated for aortic dissection. However, AMI secondary to aortic dissection is a rare condition, which might be caused by compression of the coronary arteries by a hematoma or extension of the dissection into the coronary arterial wall. Surgery is the first choice for AMI secondary to aortic dissection caused by extension of dissection into the coronary arterial wall. We present a case of inferior wall AMI caused by type I aortic dissection with presentation of chest pain and hemiparaplegia of right lower limb.

Abstract
Large, high-quality protein crystals are required for the structural determination of proteins via X-ray diffraction. In this article, we propose a technique to facilitate the production of such crystals and validate its feasibility through simulations. An analytical method for protein aqueous solution based on a Fourier transform infrared (FTIR) spectroscopy is combined with a temperature control strategy to manipulate the extent of supersaturation during crystal growth, thus impacting crystal quality. The technique requires minimal knowledge about the growth kinetics a priori. The simulations show that, under ideal conditions, the design can be as effective as predesigned temperature programs for crystallization based on known growth kinetics. Two kinds of errors might be encountered with this design. Error in the estimated number of seed crystals can result in a growth rate deviating from the desired one. Nevertheless, the deviation is usually tolerable and system instability is unlikely to occur. Based on the standard error of our FTIR method, errors in concentration measurement are simulated. Measurement error can result in system instability and impair the control algorithm. Such errors may be compensated by limiting the temperature change taken by the control action, or by improving the measurement precision through the use of regressed concentrations. Through simulations, it is shown that the proposed design is practical and represents a significant improvement over the commonly used isothermal crystallization technique.

Abstract
Fifteen-month-old Sprague-Dawley rats were given with some kinds of hot property of herb to produce model of Deficiency of yin brings about the interior heat-syndrome. The weight, water drinking volume, and body temperature of model rats were observed at the process of producing model and the treatment of di-zhen granules. Hypothalamic NE, DA and plasma NE, E concentration were determined by high-performance liquid chromatography, and serum E2, FSH, LH levels were determined by radioimmunoassay. The results were that after having been given the hot property of herbs for 2 weeks, the model rats increased water drinking volume and body temperature, which is similar to the appearance of patients with Deficiency of yin brings about the interior heat syndrome, and after having been treated with di-zhen granules, the water drinking volume and temperature of model rats decreased significantly (P < 0.01). The hypothalamic NE, DA, plasma NE, E, and the serum FSH, LH of the group treated with di-zhen granules were significantly lower than that of the model group and the normal group(P < 0.01). The results show that our model mentioned above possesses some characteristic features of the human climacteric syndrome which exhibits Deficiency of yin brings about the interior heat-syndrome. Di-zhen granules may regulate the function of GnRH neurons and other neurotic nucleus in hypothalamus, and then rectify the endocrine disorders of climacteric.

Abstract
A temperature-insensitive method for measuring protein concentration in aqueous solutions using near-infrared spectroscopy is described. The method, which is based on identification of the net analyte signal of single-beam spectra, can be calibrated using a single protein absorbance measurement and is thus well suited for crystallization monitoring where the quantity of protein is limited. The method is applied to measurements of glucose-isomerase concentration in a sodium phosphate buffer that is actively varied over the temperature range of 4-24 degrees C. The standard error of prediction using the optimized spectral range of 4670-4595 cm(-1) is 0.12 mg/mL with no systematic trend in the residuals with solution temperature. The method is also applied to previously collected spectra of hen egg-white lysozyme and yields a standard error of prediction of 0.14 mg/mL. Spectra sampled at discrete wavelengths can also be used for calibration and prediction with performance comparable to that obtained with spectral bands. A set of four wavelengths are identified that can be used to predict concentrations of both proteins with a standard error less than 0.14 mg/mL.

Abstract
Proteins possess strong absorption features in the combination range (5000-4000 cm(-1)) of the near infrared (NIR) spectrum. These features can be used for quantitative analysis. Partial least squares (PLS) regression was used to analyze NIR spectra of lysozyme with the leave-one-out, full cross-validation method. A strategy for spectral range optimization with cross-validation PLS calibration was presented. A five-factor PLS model based on the spectral range between 4720 and 4540 cm(-1) provided the best calibration model for lysozyme in aqueous solutions. For 47 samples ranging from 0.01 to 10 mg/mL, the root mean square error of prediction was 0.076 mg/mL. This result was compared with values reported in the literature for protein measurements by NIR absorption spectroscopy in human serum and animal cell culture supernatants.

Abstract
Inspecting twenty-four hours dynamic blood pressure of sixty-two essential hypertension patients with Ganyang shangkangzheng or Gan-shengyinxuzheng in normal conditions and analysing blood pressure's dynamic regularity of the two groups with different traditional Chinese medicine Zheng type, we found that the blood pressure of Ganyang shangkangzheng patients was higher in the daytime than that at night, and the Gan-Shengyinxuzheng patients had the reverse results. The results suggest that the dynamic blood pressure value may be an objective index for differential diagnosis of traditional Chinese medicine Zheng types of patients with essential hypertension.

Abstract
Digital Fourier filtering is used to produce a temperature-insensitive univariate calibration model for measuring lysozyme in aqueous solutions. Absorbance spectra over the 5000-4000 cm-1 spectral range are collected for lysozyme standards maintained at 14 degrees C. These spectra are used to compute the calibration model while a set of spectra collected at temperatures ranging from 4 to 24 degrees C are used to validate the accuracy of this model. The root-mean-square error of prediction (RMSEP) is 0.279 mg/mL over a tested lysozyme concentration range of 0.036-51.6 mg/mL. The detection limit is 0.68 mg/mL. In addition, multivariate calibration models based on partial least-squares regression (PLS) are evaluated and compared to the results from the univariate model. PLS outperforms the univariate model by providing a RMSEP of 0.090 mg/mL. Analysis of variance showed that both calibration methods effectively eliminate the adverse affects created by variations in solution temperature.

Abstract
PURPOSE To determine the effects of the Valsalva maneuver on intraluminal colon pressure during air enema studies. MATERIALS AND METHODS Air enema studies were performed in four adult volunteers, and intraluminal colon pressure measurements were recorded with a high-speed electronic strip chart and aneroid gauge methods. One hundred thirty-five Valsalva maneuvers were produced with open- and closed-glottis maneuvers, with varying degrees of straining, and during normal peristalsis. RESULTS Valsalva pressure waves are discrete waveforms that can be distinguished from baseline insufflation and normal peristaltic waves. Valsalva waves are of both simple and complex types. The range of peak Valsalva pressures was 12-148 mm Hg. Average mild, moderate, and vigorous pressures with a closed glottis were 22, 38, and 90 mm Hg, respectively. High pressures (120-130 mm Hg) were observed with open- and closed-glottis maneuvers. CONCLUSION Valsalva maneuvers increase intracolonic pressure 12-148 mm Hg above baseline pressure. Valsalva pressure waves are discrete and can be accurately detected with both aneroid and electronic transducer systems.

Abstract
Prior treatment of NG108-15 cells with phosphatase inhibitors including okadaic acid and calyculin A inhibited the elevation of cytosolic Ca2+ concentration ([Ca2+]i) induced by bradykinin by approximately 63%. This inhibition was dependent on the concentration of okadaic acid with an IC50 of 0.15 nM. Okadaic acid treatment only lowered the maximal response of [Ca2+]i increase and had no effect on the EC50 value for bradykinin regardless of the presence of extracellular Ca2+. Neither the capacity of 45Ca2+ accumulation within intracellular nonmitochondrial Ca2+ stores nor the magnitude of [Ca2+]i increase induced by thapsigargin was reduced by the treatment of okadaic acid. In contrast, the same phosphatase inhibitor treatment inhibited the bradykinin-evoked inositol 1,4,5-trisphosphate (IP3) generation, the Mn2+ influx, and the capacity of mitochondrial Ca2+ accumulation. Furthermore, the sensitivity of IP3 in the Ca2+ release was suppressed by okadaic acid pretreatment. Our results suggest that the reduction of bradykinin-induced [Ca2+]i rise by the promotion of protein phosphorylation was attributed to the reduced activity of phospholipase C, the decreased sensitivity to IP3, and the slowed rate of Ca2+ influx. Thus, phosphorylation plays a role in bradykinin-sensitive Ca2+ signaling cascade in NG108-15 cells.
