Abstract
Objective: To investigate the characteristics of neointimal hyperplasia (NIH) in patients with in-stent restenosis (ISR) over 5 years post-drug-eluting stent (DES) implantation based on optical coherence tomography (OCT). Methods: In this cross-sectional study, patients with DES-ISR who underwent OCT examination at PLA General Hospital between March 2010 and March 2022 were retrospectively included. All patients were divided into≤5 years DES-ISR group and>5 years DES-ISR group according to the time interval after DES implantation. Quantitative and qualitative analyses were conducted on OCT images to compare the clinical data and lesion characteristics of two patient groups. Furthermore, the independent clinical predictive factors of in-stent neoatherosclerosis (ISNA) were analyzed by multivariable logistic regression. Results: A total of 230 DES-ISR patients with 249 lesions were included, with an age of (63.1±10.4) years and 188 males (81.7%). The median interval after DES implantation was 6 (2, 9) years. There were 117 patients (122 ISR lesions) in the≤5 years DES-ISR group, and 113 patients (127 ISR lesions) in the>5 years DES-ISR group. Compared with≤5 years DES-ISR,>5 years DES-ISR showed more heterogeneous patterns (65.4% (83/127) vs. 48.4% (59/122), P=0.007), diffuse patterns (46.5% (59/127) vs. 31.2% (38/122), P=0.013), macrophage accumulations (44.1% (56/127) vs. 31.2% (38/122), P=0.035) in NIH and higher prevalence of ISNA (83.5% (106/127) vs. 72.1% (88/122), P=0.031). According to multivariable logistic regression, the independent predictive factor for ISNA was female (OR=0.44, 95%CI 0.21-0.90, P=0.026). Female (OR=0.48, 95%CI 0.23-0.99, P=0.046) and low-density lipoprotein cholesterol level (OR=1.62, 95%CI 1.01-2.59, P=0.046) were independent predictive factors, respectively, for lipid ISNA. Calcified ISNA was independently associated with time interval of post-DES implantation (OR=1.18, 95%CI 1.07-1.29, P=0.001). Conclusion: DES-ISR patients with a time interval of>5 years after stent implantation have a higher prevalence of ISNA and more complex lesions. Gender, the level of low-density lipoprotein cholesterol, and the time interval post-DES implantation are independently correlated with ISNA, lipid ISNA, and calcified ISNA.

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
Objective: To evaluate the protective effect of jailed balloon technique on side branch (SB) ostium using three-dimensional optical coherence tomography(OCT). Methods: This is a retrospective study. Consecutive coronary disease patients with coronary artery bifurcation lesions who underwent percutaneous coronary intervention (PCI) and completed pre-and post-procedural OCT examinations at the Chinese People's Liberation Army General Hospital from September 2019 to March 2022 were enrolled. Patients were divided into the jailed balloon technique group and the unprotected group according to the options applied for the SB. The SB ostium area difference was calculated from OCT images (SB ostium area difference=post-PCI SB ostium area-pre-PCI SB ostium area). The SB ostium area differences were compared between the two groups and compared further in the subgroup of true bifurcation lesions and non-true bifurcation lesions. In the jailed balloon group, the SB ostium area difference was compared between the active jailed balloon technique and the conventional jailed balloon technique, between the jailed balloon>2.0 mm diameter and the jailed balloon≤2.0 mm diameter, and between the higher balloon pressure (>4 atm, 1 atm=101.325 kPa) and the lower balloon pressure (≤4 atm). Multivariate linear regression analysis was used to explore the correlation between the technical parameters of the jailed balloon technique and the SB protection effect. Results: A total of 176 patients with 236 bifurcation lesions were enrolled, aged (60.7±9.3) years, and there were 128 male patients (72.7%). There were 67 patients in the jailed balloon technique group with 71 bifurcation lesions and 123 patients in the unprotected group with 165 bifurcation lesions. Fourteen patients had 2 to 3 lesions, which were treated in different ways, so they appeared in the unprotected group and the jailed balloon technique group at the same time. The area difference in SB ostium was greater in the jailed balloon group than in the unprotected group (0.07 (-0.43, 1.05)mm2 vs.-0.33 (-0.83, 0.26)mm2, P<0.001), and the results were consistent in the true bifurcation lesion subgroup (0.29 (-0.35, 0.96)mm2 vs.-0.26 (-0.64, 0.29)mm2, P=0.004), while the difference between the two groups in the non-true bifurcation lesion subgroup was not statistically significant (P=0.136). In the jailed balloon technique group, the SB ostium area difference was greater in patients treated with the active jailed balloon technique than in those treated with the conventional jailed balloon technique ((0.43±1.36)mm2 vs. (-0.22±0.52)mm2, P=0.013). The difference in SB ostium area was greater in those using>2.0 mm diameter jailed balloons than in those using≤2.0 mm diameter jailed balloons (0.25 (-0.51, 1.31) mm2 vs.-0.01 (-0.45, 0.63) mm2, P=0.020), while SB ostium area difference was similar between those endowed with higher balloon pressure (>4 atm) compared to those with lower balloon pressure (≤4 atm) (P=0.731). Multivariate linear regression analysis showed that there was a positive correlation between jailed balloon diameter and SB ostium area difference (r=0.344, P=0.019). Conclusions: The jailed balloon technique significantly protects SB ostium, especially in patients with true bifurcation lesions. The active jailed balloon technique and larger diameter balloons may provide more protection to the SB.

Abstract
Healthy life expectancy is based on life expectancy to further identify the healthy component, moving the assessment threshold from the mortality to the whole life cycle, receiving more and more attention worldwide. Nowadays, it has become one of the core indicators of national major strategy and plan. As a comprehensive indicator of health measurement, healthy life expectancy is complicated and multi-dimensional. Different social and cultural backgrounds have different understandings of health and choose different measurement dimensions. Overall, although high-income countries have different choices in their national health plan, healthy life expectancy without activity restriction is by far the most widely used indicator. This paper reviewed the concept and application of healthy life expectancy systematically, drawing on international practical experience to provide reference for the establishment of a healthy life expectancy indicator system in line with the Chinese national conditions.

Abstract
OBJECTIVE To observe the efficacy of acupuncture on symptom burden in patients with gastric cancer during adjuvant chemotherapy after gastrectomy. METHODS A total of 58 patients were randomized into a high-dose acupuncture group (19 cases, 5 cases dropped off), a low-dose acupuncture group (20 cases, 6 cases dropped off) and a control group (19 cases, 2 cases dropped off). Conventional chemotherapy and antiemetic treatment were adopted in the control group. On the basis of the treatment in the control group, acupuncture was applied 7 times each chemotherapy cycle for totally 21 times in the high-dose acupuncture group, and 3 times each chemotherapy cycle for totally 9 times in the low-dose acupuncture group. Baihui (GV 20), Zusanli (ST 36), Neiguan (PC 6), etc. were selected in the two acupuncture groups, as well as back-shu points selected by the meridian heat sensing technique. Electroacupuncture was connected to ipsilateral Zusanli (ST 36) and Neiguan (PC 6), with continuous wave, 2 Hz in frequency for 20 min. The Edmonton symptom assessment system (ESAS) score was observed on day 1-7, 14, and 21 of each cycle of chemotherapy respectively in the 3 groups. RESULTS The symptom burden was worst within 7 days of each cycle of chemotherapy in the 3 groups. After the 3rd chemotherapy cycle, the total score of ESAS in the low-dose acupuncture group was lower than the control group (P<0.05), the total score and the scores of feeling of non-well being, pain and shortness of breath of ESAS in the acupuncture group (the high-dose acupuncture group combined with the low-dose acupuncture group) were lower than the control group (P<0.05). CONCLUSION Acupuncture shows promising effect in controlling symptom burden during adjuvant chemotherapy in gastric cancer patients after gastrectomy.

Abstract
Gastrointestinal cancers (GICs) occupy more than 30% of the cancer-related incidence and mortality around the world. Despite advances in the treatment strategies, the long-term overall survival has not been improved for patients with GICs. Recently, the novel patient-derived organoid (PDO) culture technology has become a powerful tool for GICs in a manner that recapitulates the morphology, pathology, genetic, phenotypic, and behavior traits of the original tumors. Excitingly, a number of evidences suggest that the versatile technology has great potential for personalized treatment, suppling the clinical application of molecularly guided personalized treatment. In the paper, we summarize the literature on the topics of establishing organoid biobanks of PDOs, and their application in the personalized treatment allowing for radiotherapy, chemotherapy, targeted therapy, and immunotherapy selection for GICs. Despite the limitations of current organoid models, high-throughput drug screening of GIC PDO combined with next-generation sequencing technology represents a novel and pivotal preclinical model for precision medicine of tumors and has a great value in promoting the transformation from basic cancer research to clinical application.

Abstract
The advent of coronary CT angiography derived fractional flow reserve (CT-FFR) calculation technology has brought great improvements to the clinical diagnostic process and treatment decision-making towards coronary artery disease. In recent years, CT-FFR technology has gradually begun to be taken into clinical practice in China, however, currently, the popularization is not widespread, and it is imperative to further standardize the clinical application of CT-FFR technology. This paper focused on the opportunities, significance and challenges of CT-FFR application in China from the advantages and disadvantages perspectives of this new technology based on three international studies. Combined with specific national conditions and the latest evidence-based clinical medical results, this paper proposes a win-win cooperation initiative between cardiologists and radiologists for the reference and caution of both clinical practitioners and medical affairs bureaus.

Abstract
BACKGROUND Along with increasing research on acupuncture for chronic pain, the validity of sham acupuncture (SA) has also been argued. METHODS Nine databases were searched for randomized controlled trials (RCTs) from the inception date to July 5, 2022. Using Markov Chain Monte Carlo methods, a Bayesian multiple treatment network meta-analysis (NMA) with random-effects model was conducted. RESULTS A total of 62 RCTs with 6806 patients and four kinds of treatments (real acupuncture (RA), non-acupuncture (NA), penetrative SA (PSA) and non-penetrative SA (NPSA)) were included. The results indicated that both NPSA and PSA were not superior to NA in improving chronic pain (NPSA: MD -4.77 [95% CI, -11.09 to 1.52]; PSA: MD, -4.96 [95% CI, -10.38 to 0.48]). After combining NPSA and PSA into the SA group, the weak trend of pain relief from SA was still not statistically significant (MD, -4.91 [95% CI, -9.93 to 0.05]). NPSA and PSA had similar effects (MD, 0.18 [95% CI, -5.45 to 5.81]). RA was significantly associated with pain relief, compared with NPSA and PSA (NPSA: MD, -12.03 [95% CI, -16.62 to -7.41]; PSA: MD, -11.85 [95% CI, -15.48 to -8.23]). The results were generally consistent regardless of pain phenotype, frequency, duration, acupuncture methods, analgesic intake, or detection bias. CONCLUSION These results suggested that acupuncture was significantly associated with reduced chronic pain. The two kinds of placebo acupuncture, NPSA and PSA, have similar effects. Both NPSA and PSA, with a weak but not significant effect, are appropriate to be inert placebo controls in RCTs for chronic pain.

Retrospectively, we manually annotated 26,465 transthoracic echocardiography images into 29 classes for model development in 4:1 ratio as training and validation datasets. We added an autoencoder component into our model, adapted from capsule net, for view-classifying to deconvolute the feature maps of last layer as decoder for human interpretation. The performance of view classification was measured in accuracy and confusion matrix, and the interpretability of model were assessed by cardiologist.
Result
After appropriate model training, the accuracy of our model achieved averaged 98.2% for echocardiography view classification, ranged from lowest 80.0% in suprasternal view to 100% of several more common view in validation dataset. The successful deconvolution of feature map to reconstruct images showed essential independent components of echocardiography view and could be interpretated by cardiologist and clinical physicians.
Conclusion
With the use of autoencoder in model for echocardiography view classification showed maintainable good performance in accuracy and facilitated clinical interpretation to enhance its reliability.

Abstract
CONTEXT Patients with gastric cancer experience health-related quality of life (HRQOL) decline during adjuvant chemotherapy following gastrectomy. OBJECTIVES This pilot study aimed to evaluate the preliminary effect and feasibility of electro-acupuncture (EA) for HRQOL and symptom burden in these patients. METHODS In this open-label, multicenter, parallel controlled trial, gastric cancer patients who planned to receive adjuvant chemotherapy were randomly assigned to receive high-dose EA (seven times each chemotherapy cycle for three cycles), low-dose EA (three times each chemotherapy cycle), or usual care only. The acupoints prescription consisted of bilateral ST36, PC6, SP4, and DU20, EX-HN3, and selected Back-shu points. Patients completed the Functional Assessment of Cancer Therapy-Gastric (FACT-Ga) weekly, and the Edmonton Symptom Assessment System (ESAS). The primary outcome was the difference among the groups on the gastric cancer subscale (GaCS) of the FACT-Ga. RESULTS Of the 66 randomized patients, 58 were analyzed according to intention-to-treat principle, and 45 were in the per-protocol set (PPS). The average scores in PPS of GaCS were 52.12±9.71, 51.85±12.36, and 45.37±8.61 in high-dose EA, low-dose EA, and control groups, respectively. EA was significantly associated with improved average GaCS scores when compared with control group (51.98±10.91 vs. 45.37±8.61, P = 0.039). EA treatment also produced ESAS relief at the end of intervention (14.36 ± 12.28 vs. 23.91 ± 15.52, P = 0.027). Participants in EA groups had fewer grade ≥3 leukopenia (0% vs. 15.79%, P = 0.031) and neutropenia (2.56% vs. 26.31%, P = 0.012). CONCLUSION EA showed promising effects in improving HRQOL, controlling symptom burden, and reducing toxicity during adjuvant chemotherapy in gastric cancer patients. Future adequately powered trials are feasible and needed to confirm the specific effect of EA.

Abstract
Objective: To develop a pretest probability model of obstructive coronary artery disease with machine learning based on multi-site Chinese population data. Methods: Chinese regiStry in early deTection and Risk strAtificaTion of coronary plaques (C-Strat) study is a prospective multi-center cohort study, in which consecutive patients with suspected obstructive coronary artery disease and ≥64 detector row coronary computed tomography angioplasty (CCTA) evaluation were included. Data from the patients were randomly split into a training set (70%) and a test set (30%). More than 50% of coronary artery stenosis by CCTA was defined as positive outcome. A boosted ensemble algorithm (XGBoost), 10-fold cross-validation and Bayesian optimization were used to establish a new prediction model-CARDIACS(pretest probability model from Chinese registry in eARly Detection and rIsk stratificAtion of Coronary plaques Study), and a logistic regression was used to establish a model-LOGISTIC in training set. The test set was used for validation and comparison among CARDIACS, LOGISTIC, UDFM (updated Diamond-Forrester Model) and DFCASS(Diamond-Forrester and CASS). Results: The study population included 29 455 patients with age of (57.0±9.7) years and 44.8% women, of whom 19.1% (5 622/29 455) had obstructive coronary artery disease. For CARDIACS, the age, the reason for visit and the body mass index (BMI) were the most important predictive variables. In the independent test set, the area under the curve (AUC) of CARDIACS was 0.72 (95%CI 0.70-0.73), which was significantly superior to that of LOGISTIC (AUC 0.69, 95%CI 0.68-0.71, P=0.015), UDFM (AUC 0.64, 95%CI 0.62-0.65, P<0.001) and DFCASS (AUC 0.66, 95%CI 0.64-0.67, P<0.001), respectively. Conclusion: Based on Chinese population, the study developed a new pretest probability model--CARDIACS, which was superior to the traditional models. CARDIACS is expected to assist in the clinical decision-making for patients with stable chest pain.

Abstract
In the WHO new road map for neglected tropical diseases 2021-2030, the disease-specific targets are classified into control, elimination as a public health problem, elimination and eradication, and taeniasis and cysticercosis are targeted for control. The overall prevalence of taeniasis and cysticercosis is low in China, and varies remarkably in regions and populations; however, there are many challenges for elimination of taeniasis and cysticercosis in China. Based on previous taeniasis and cysticercosis control programs, developing a sensitive taeniasis and cysticercosis surveillance-response system, updating criteria for diagnosis of taeniasis and cysticercosis, proposing a national guideline for treatment of taeniasis and cysticercosis, and strengthening interdisciplinary and intersectoral communications and collaborations are urgently needed under the One Health concept.

Abstract
Background Whereas there are many pharmacological interventions prescribed for patients with advanced anaplastic lymphoma kinase (ALK)- rearranged non-small cell lung cancer (NSCLC), comparative data between novel generation ALK-tyrosine kinase inhibitors (TKIs) remain scant. Here, we indirectly compared the efficacy and safety of first-line systemic therapeutic options used for the treatment of ALK-rearranged NSCLC. Methods We included all phase 2 and 3 randomised controlled trials (RCTs) comparing any two or three treatment options. Eligible studies reported at least one of the following outcomes: progression free survival (PFS), overall survival (OS), objective response rate (ORR), or adverse events of grade 3 or higher (Grade ≥ 3 AEs). Subgroup analysis was conducted according to central nervous system (CNS) metastases. Results A total of 9 RCTs consisting of 2484 patients with 8 treatment options were included in the systematic review. Our analysis showed that alectinib (300 mg and 600 mg), brigatinib, lorlatinib and ensartinib yielded the most favorable PFS. Whereas there was no significant OS or ORR difference among the ALK-TKIs. According to Bayesian ranking profiles, lorlatinib, alectinib 600 mg and alectinib 300 mg had the best PFS (63.7%), OS (35.9%) and ORR (37%), respectively. On the other hand, ceritinib showed the highest rate of severe adverse events (60%). Conclusion Our analysis indicated that alectinib and lorlatinib might be associated with the best therapeutic efficacy in first-line treatment for major population of advanced NSCLC patients with ALK-rearrangement. However, since there is little comparative evidence on the treatment options, there is need for relative trials to fully determine the best treatment options as well as the rapidly evolving treatment landscape.

Abstract
Dental caries have become a major global public health problem. Plaque control and remineralization of initial enamel lesions are paramount for the prevention and control of caries. Polyhexamethylene biguanide (PHMB) is a type of cationic amphipathic antibacterial agent with broad-spectrum antibacterial properties and good biological safety. Fluoride delays demineralization and promotes the remineralization of hard dental tissues. However, a high concentration is needed for it to function as an antibacterial agent. In order to create a PHMB with the benefits associated with fluoride, we synthesized a fluorine-containing cationic polymer, PHMB-F. Fourier transform-infrared spectroscopy and solid state nuclear magnetic resonance characterization confirmed the successful synthesis of PHMB-F. Antibacterial tests showed that PHMB-F had better antiseptic efficacy for Streptococcus mutans compared with just PHMB. Moreover, positively-charged PHMB-F allows fluoride ions to exist closer to the enamel surface with negative potential, which markedly lowers the ion concentrations in the microenvironment adjacent to hard dental tissues needed to maintain equilibrium. Thus, only low concentrations of PHMB-F are required for enamel remineralization.

Abstract
OBJECTIVE To understand the prevalence of soil-borne nematode infections among residents living in urban/town areas of China, so as to provide insights into the control and elimination of soil-borne nematodiasis. METHODS A total of 5 epidemic areas were classified in China according to the prevalence of human Clonorchis sinensis infections captured from the 2014-2015 national survey on major human parasitic diseases in China, and the total sample size was estimated according to the binomial distribution and Poisson's distribution. Then, the total sample size was allocated proportionally to each province (autonomous region, municipality) of China based on the percentage of residents living in urban and town areas, and the number of survey sites in each province (autonomous region, municipality) was proportionally assigned according to the percentages of residents living in urban and town areas. Then, stratified sampling was performed at county, township and community levels according to the number of sampling sites in each province (autonomous region, municipality), and the survey site (community) was defined as the smallest sampling unit. All permanent residents in the survey sites were selected as the study subjects, and their stool samples were collected for identification and counting of parasite egg using a Kato-Katz technique. The prevalence and intensity of each parasite species were calculated. RESULTS From 2014 to 2015, among the 133 231 residents detected in 31 provinces (autonomous regions, municipalities) of China, the overall prevalence of soil-borne nematode infections was 1.23% (1 636/133 231), and the prevalence rates of hookworm, Ascaris lumbricoides and Trichuris trichiura infections were 0.77% (1 032/133 231), 0.32% (426/133 231) and 0.17% (224/133 231), respectively. The highest prevalence of soil-borne nematode infections was seen in Jiangxi (4.03%, 82/2 034) and Chongqing (4.03%, 524/13 012), followed by in Hainan (3.47%, 72/2 075). The prevalence of soilborne nematode infections was 1.07% (662/62 139) in men and 1.37% (974/71 092) in women, and the greatest prevalence was found in residents at ages of 65 to 70 years (2.56%, 219/8 569). With regard to occupations and education levels, herdsmen (2.47%, 2/81) and illiterate residents (3.33%, 226/6 795) were found to have the highest prevalence of soil-borne nematode infections, respectively. In addition, mild infections were predominantly identified in hookworm-, A. lumbricoides- and T. trichiura-infected individuals (all > 90%). CONCLUSIONS The overall prevalence of soil-borne nematodiasis remains low in urban and town areas of China; however, human infections are widespread. According to the epidemiological features, health education combined with deworming are recommended to reduce the prevalence of soil-borne nematode infections among residents living in urban and town areas of China.

Abstract
The zinc finger transcription factor Snail is aberrantly activated in many human cancers and associated with poor prognosis. Therefore, targeting Snail is expected to exert therapeutic benefit in patients with cancer. However, Snail has traditionally been considered "undruggable," and no effective pharmacological inhibitors have been identified. Here, we found a small-molecule compound CYD19 that forms a high-affinity interaction with the evolutionarily conserved arginine-174 pocket of Snail protein. In aggressive cancer cells, CYD19 binds to Snail and thus disrupts Snail's interaction with CREB-binding protein (CBP)/p300, which consequently impairs CBP/p300-mediated Snail acetylation and then promotes its degradation through the ubiquitin-proteasome pathway. Moreover, CYD19 restores Snail-dependent repression of wild-type p53, thus reducing tumor growth and survival in vitro and in vivo. In addition, CYD19 reverses Snail-mediated epithelial-mesenchymal transition (EMT) and impairs EMT-associated tumor invasion and metastasis. Our findings demonstrate that pharmacologically targeting Snail by CYD19 may exert potent therapeutic effects in patients with cancer.

Abstract
Objective: To understand the characteristics and changes of the incidence of amoebic dysentery in China during 2015-2018, explore the causes of high incidence in some areas and provide a data base for the development of national prevention and control strategies and measures. Methods: Data were collected from the infectious disease reporting management information system from Chinese Disease Control and Prevention. To understand the seasonal, population and area distributions of amoebic dysentery, descriptive epidemiological method and software SPSS 16.0 were used to analyze the amoebic dysentery data. Results: A total of 4 366 amoebic dysentery cases were reported without death in China during 2015-2018. The reported average annual incidence was 0.08/100 000, and the overall proportion of laboratory confirmed cases was 68.23%(2 979/4 366). Amoeba dysentery mainly occurred during May to October. One seasonal peak was observed in 2015 and 2017 (July and June, respectively), and two seasonal peaks were observed in 2016 and 2018 (June and October). The patients were mainly children aged under 5 years (42.28%, 1 846/4 366), and the incidence rate decreased with age in children aged under 10 years. Of these, children under 1 years of age had the highest incidence rate (1.28/100 000). The number of cumulative reported cases in Guangxi, Henan, Guangdong, Heilongjiang and Jiangxi provinces ranked top five from 2015-2018, accounting for 64.50% (2 816/4 366) of the total. The cumulative cases in Dongxing county, Guangxi, in Suixian county, Henan and in Ranghulu district, Heilongjiang, respectively accounted for more than 50.00% of the total number of cases in their provinces. Conclusions: The incidence rate of amoebic dysentery reported in China during 2015-2018 showed a decreasing trend, with a higher incidence in children under 5 years old and a higher number of cases in some areas. It is suggested to further investigate and analyze the diagnosis and reporting of amoeba dysentery in key areas and promote the update of the diagnostic standards for amoeba dysentery.

Abstract
OBJECTIVE To understand the epidemic status of Enterobius vermicularis infections among children aged 3 to 9 years in China, so as to provide scientific basis for the formulation of the prevention and control strategies for enterobiasis. METHODS The national surveillance of enterobiasis was performed in 736 national surveillance sites (counties) from 30 provinces (municipalities/autonomous regions) in China from 2016 to 2018. All surveillance sites were classified into parts according to the geographical directions, including the eastern, western, southern, northern and middle parts, and a township was randomly selected from each part. Then, an administrative village was randomly selected from the township, and 200 permanent residents at ages of over 3 years living in the administrative village were randomly selected using the cluster sampling method. A total of 1 000 residents were examined in each surveillance site. E. vermicularis infections were detected among children at ages of 3 to 9 years using the modified Kato-Katz technique and the adhesive cellophane-tape perianal swab method, and the prevalence of infections was calculated and compared. RESULTS The prevalence of E. vermicularis infections was 2.50%, 2.84% and 2.46% among children at ages of 3 to 9 years in the 736 surveillance sites from 30 provinces (municipalities/autonomous regions) in China from 2016 to 2018, and there was no gender-specific prevalence of E. vermicularis infections (P > 0.05). Enterobiasis was main prevalent in the southern and southwestern part of China (Jiangxi, Guangxi, Guangdong, Sichuan, Fujian, Chongqing and Hainan), with 5.00% prevalence and greater, and the highest prevalence was seen in Jiangxi and Guangxi for successive 3 years. In addition, the prevalence of E. vermicularis infections was higher in children with the Han ethnicity than in those with the minority ethnicity, and a high prevalence was found in children at ages of 4 to 7 years, and a low prevalence seen in children at ages of 3, 8 and 9 years. CONCLUSIONS The prevalences of E. vermicularis infections have not changed much among children at ages of 3 to 9 years in China from 2016 to 2018, and high prevalence is seen in southern and southwestern China, which should be given a high priority.

Abstract
Tumor necrosis factor (TNF) receptor-associated factors (TRAFs) play crucial roles as signaling mediators for the TNF receptor (TNFR) superfamily and the interleukin-1 receptor/Toll-like receptor (IL-1R/TLR) superfamily. TRAFs collectively play important roles in multiple biological processes and organismal immunity. However, systematic identification of the TRAF gene family in teleost fish has not yet been reported, and there is little available information about its roles in innate immunity in Chinese tongue sole (Cynoglossus semilaevis), an aquaculture fish of high economic value. In the present study, we identified and characterized seven TRAF genes, namely, CsTRAF2a, CsTRAF2b, CsTRAF3, CsTRAF4, CsTRAF5, CsTRAF6 and CsTRAF7, in Chinese tongue sole, and the complete ORFs of the CsTRAFs were cloned. Sequence analysis revealed various genomic structures of the CsTRAFs and showed that they contain typical conserved domains compared with mammalian TRAFs. Phylogenetic analysis indicated the evolutionary relationships of TRAF family members in teleost fish and revealed an absence of TRAF1 in most species and TRAF5 in some species of teleosts. Analysis of the gene structures and motifs showed the diversity and distribution of exon-intron structures and conserved motifs in Chinese tongue sole and several other teleost species. Real-time quantitative PCR was used to investigate the expression patterns of CsTRAF genes in tissues of healthy fish and in the gills, livers and spleens of fish after bacterial infection with Vibrio harveyi. The results indicate that only CsTRAF2a is relatively highly expressed in the brain and that the other CsTRAFs are highly expressed in immune-related tissues and may participate in the immune response after infection with pathogenic bacteria. Functional analysis of CsTRAF3, CsTRAF4 and CsTRAF6 revealed that only CsTRAF6 could strongly activate the NF-кB pathway after overexpression of CsTRAF3, CsTRAF4 and CsTRAF6 in HEK-293T cells. This systematic analysis provided valuable information about the diverse roles of TRAFs in the innate immune response to pathogenic bacterial infection in teleost fish and will contribute to the functional characterization of CsTRAF genes in further research.

Abstract
OBJECTIVE To establish an evaluation system for the field assessment of the Kato-Katz technique in detecting soiltransmitted nematodes, so as to provide insights into the field application of the Kato-Katz technique. METHODS The initial evaluation indicators were determined through literature search, brainstorming and expert consultation. The evaluation indicatorswere improved and the weight of each indicator was decided through three rounds of expert consultation by using the Delphimethod. In addition, the expert authority coefficient and the coordination coefficient of each indicator were calculated at eachround of expert consultations. RESULTS The recovery rates of the questionnaire were 100.00%, 100.00% and 89.29% at the firstto the third round of the expert consultations, respectively, and the expert authority coefficients were all more than 0.85 at eachround. The final evaluation system included 4 first-level indicators and 15 second-level indicators. In the first-level indicators, "detecting effect" and "funds investment" had the mean weighted value of 4.53 and 4.49, which were relatively higher than that of"person-time investment" and "operability" (both 4.34). Among the second-level indicators under each first-level indicator, thefour most significant indicators included "ability of personnel in egg discrimination", "cooperation of village cadres and doctors","Person-time on testing" and "organizational start-up cost", with the mean weighted values of 4.74, 4.43, 4.39 and 4.17, respectively. The coordination coefficients were 0.39 to 0.65, 0.28 to 0.58 and 0.45 to 0.65 at the first to the third round of the expertconsultations, respectively, and there were significant differences in the coordination coefficients at all three rounds of the consultations (all P < 0.05). CONCLUSIONS An evaluation system for the field assessment of the Kato-Katz technique in detecting soiltransmitted nematodes is successfully established, among which "ability of personnel in egg discrimination" and "cooperation ofvillage cadres and doctors" have the greatest mean weighted values of the significance.

Abstract
INTRODUCTION Acetyl-CoA Carboxylases (ACC) have been an important target for the therapy of metabolic syndrome, such as obesity, hepatic steatosis, insulin resistance, dyslipidemia, non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), type 2 diabetes (T2DM), and some other diseases. METHODS In this study, virtual screening strategy combined with Bayesian categorization modeling, molecular docking and binding site analysis with protein ligand interaction fingerprint (PLIF) was adopted to validate some potent ACC inhibitors. First, the best Bayesian model with an excellent value of Area Under Curve (AUC) value (training set AUC: 0.972, test set AUC: 0.955) was used to screen compounds of validation library. Then the compounds screened by best Bayesian model were further screened by molecule docking again. RESULTS Finally, the hit compounds evaluated with four percentages (1%, 2%, 5%, 10%) were verified to reveal enrichment rates for the compounds. The combination of the ligandbased Bayesian model and structure-based virtual screening resulted in the identification of top four compounds which exhibited excellent IC 50 values against ACC in top 1% of the validation library. CONCLUSION In summary, the whole strategy is of high efficiency, and would be helpful for the discovery of ACC inhibitors and some other target inhibitors.

Abstract
At the time of the 40th anniversary of the Alma-Ata Declaration, the World Health Organization member states signed the Declaration of Astana. From Health For All to Universal Health Coverage, primary health care is consistantly identified as the key to achieving human health, and preventive services are critical and central component of primary health care. China has provided valuable experience for primary health care to countries around the world. However, with significant socioeconomic changes and rapid population aging, the contexts of primary health care and prevention services in China has undergone tremendous changes. Chronic diseases have become major burden of disease. System development and institution building, health service delivery system development, and the entire society of the country with large population are encountering new and serious challenges. On the basis of reviewing the development of preventive medical services in China for 40 years, Authors analyzes strengths and weaknesses of preventive services in China and looks forward to the challenges and opportunities in the coming decades, from perspective of primary, secondary and tertiary prevention strategies, and proposes suggestions for future development.

Abstract
A full-length cDNA encoding phosphatidylinositol 3-kinase regulatory subunit gamma b gene in Nile tilapia (Oreochromis niloticus), termed as On-pik3r3b, was identified and characterized in this study. The sequence analysis demonstrated that the full-length cDNA of On-pik3r3b was 2018 bp, containing a 5' untranslated region (UTR) of 171 bp, an open reading frame (ORF) of 1422 bp and a 3' UTR of 425 bp. Its protein sequence displayed a high degree of identity with other fish. Using qPCR, the expression patterns of On-pik3r3b were investigated. In healthy Nile tilapia, the transcripts of On-pik3r3b were detected in all examined tissues, except the skin. Upon the stimulation with Streptococcus agalactiae, the On-pik3r3b expression level in liver, spleen, kidney and gill were significantly increased at 12 h after infection. The recombinant On-pik3r3b showed in vitro antibacterial activity, against S. agalactiae and E. coli. Our observation strongly indicates that On-pik3r3b is involved in the innate immune response in Nile tilapia.

Abstract
Cholesterol gallstones (CS) are a common disease of the digestive system. The imbalance of cholesterol and bile acid metabolism tends to result in the deposition of cholesterol crystals, which is the basis of gallstone formation. Current guidelines recommend cholecystectomy for CS patients with any symptoms. Nevertheless, there are still some patients without surgical indications, surgical conditions, or surgical consent, who may be benefit from non-surgical treatment. However, there are not too many tips for non-surgical treatment of CS in latest guidelines, nor sufficient attention paid form clinicians. This paper reviews the relevant recent literature on non-surgical treatment of CS, with an aim to help clinicians be familiar with non-surgical treatment of CS.

Abstract
BACKGROUND FLT3 is a member of receptor tyrosine kinase III family, mainly expressed in hematopoietic cells. The aberrant expression and function of FLT3 are strongly related to leukemia, especially acute myeloid leukemia. Its varieties of amino-acid residues mutations, such as FLT3-ITDs and -TKDs, can induce constant proliferation of hematological tumor cells with poor prognosis. Hence FLT3 serves as a promising target in AML chemotherapy. OBJECTIVE This review focused on the progress of FLT3 inhibitors study including those that have entered clinical trials or were reported in numerous patents all over the world. Thus, we provided a useful reference for the development of new anti-leukemia drugs. METHOD Through a comprehensive retrospective study, FLT3 inhibitors in several patent applications were identified and classified into five categories, including quinolone-related, indole-related, ureas, pyrimidines and other compounds. RESULTS For each category of compounds, the structural feature, SAR, biological activity and current research status were thoroughly reviewed and analyzed. CONCLUSION Although some of those compounds expressed potent bioactivities and have reached the advanced clinical trials for the treatment of leukemia, there are still several problems need to be faced before they enter the market eventually, especially the drug resistance issue. The improvement of therapeutic potency for FLT3 inhibitors might depend on the useful combination therapy and further refinement of the intrinsic properties of FLT3 inhibitors.

Abstract
In mammals, microtubule-dependent trafficking could participate the immune response, where the motor proteins are suggested to play an important role in this process, while the related study in fish was rare. In this study, dctn5, a subunit of dyactin complex for docking motor protein, was obtained by previous immune QTL screening. The full-length cDNAs of two dctn5 transcript variants were cloned and identified (named dctn5_tv1 and dctn5_tv2, respectively). Tissue distribution showed that dctn5_tv1 was widely distributed and high transcription was observed in immune tissue (skin), while dctn5_tv2 was predominantly detected in gonad and very low in other tissues. Time-course expression analysis revealed that dctn5_tv1 could be up-regulated in gill, intestine, skin, spleen, and kidney after Vibrio harveyi challenge. Moreover, recombinant Dctn5_tv1 exhibited high antimicrobial activity against Escherichia coli and Streptococcus agalactiae due to binding to bacteria cells. Taken together, these data suggest Dctn5_tv1 is involved in immune response of bacterial invasion in Chinese tongue sole.

Abstract
Since the first report of endoscopic retrograde cholangio-pancreatography (ERCP) in 1986 for the diagnosis of biliary-pancreatic disease, ERCP has become an important means for the diagnosis and treatment of biliary-pancreatic disease. At present, although the success rate of endoscopic selective biliary cannulation is more than 90%, there are still 5%-10% of cases with failed cannulation, for which assistive technology is needed as a supplementary to achieve successful cannulation. Repeated attempts correlate with a higher success rate of cannulation, but also extend the operating time and increase the incidence of complications. In recent years, the concept of difficult biliary cannulation has been put forward and gradually accepted by endoscopic physicians. In the cases of difficult biliary cannulation, endoscopic physicians can adjust the cannulation strategy in time to improve the success rate and reduce the complication rate. This paper summarizes the literature published recently to make a systematic review of the advances in the management of difficult biliary cannulation.

Abstract
UNLABELLED This study aimed to reveal the incidence of clinical endpoints in elderly patients with atrial fibrillation (AF) during a 2-year follow-up and evaluate the related prognostic factors of these endpoints.In total, 200 elderly patients with AF and 400 age- and sex-matched patients without AF were enrolled in this prospective observational cohort study. The incidence of clinical endpoints, including thromboembolism, hemorrhage, and all-cause death, during the 2-year follow-up was analyzed. Other follow-up data, including disease history, laboratory examinations, medication status, and other clinical endpoints, were collected. The prognostic factors of these clinical endpoints were then evaluated by Cox-survival analysis. In addition, the predicative role of C-reactive protein (CRP) and platelet-activating factor (PAF) on these clinical endpoints was analyzed.The incidence of clinical endpoints, including thromboembolism, hemorrhage, and all-cause death, was significantly higher in patients with AF than in those without AF (27.8% vs 9.8%, 29.4% vs 12.7%, and 28.7% vs 11.6%, respectively; all P < .001). Antithrombotic therapy significantly reduced the incidences of all-cause deaths (P < .05). Body mass index (BMI) and digoxin were prognostic risk factors of thromboembolism; age, massive hemorrhage history, and digoxin were prognostic risk factors of hemorrhage and age, renal insufficiency history, massive hemorrhage history, and digoxin were prognostic risk factors of all-cause death (P < .05). Further, both CRP and PAF were prognostic risk factors of thromboembolism and massive hemorrhage (P < .05).Age, BMI, massive hemorrhage history, and digoxin appear to be prognostic risk factors of clinical endpoints in elderly patients with AF. Appropriate drug use during follow-up may be beneficial in preventing the occurrence of clinical endpoints in elderly patients with AF. TRIAL REGISTRATION NUMBER ChiCTR-OCH-13003479.

Abstract
Objective: The aim of the current study was to investigate the predictive value of fragmented QRS wave ( fQRS) for the prognosis of patients with coronary heart disease (CHD). Methods: A total of 714 consecutive patients with confirmed CHD were included from Department of Cardiology, General Hospital of PLA between January 2013 and January 2014, and were divided into fQRS group and non-fQRS group based on the presence of fQRS wave or not according to Electrocardiograph (ECG). The baseline, ECG characteristic value, the echocardiography results of the patients were compared between the two groups. Cardiac events were recorded in all patients during 12 months' follow-up. Subgroup analysis was also conducted among patients with abnormal Q wave to investigate the association between fQRS and cardiovascular events. Results: A total of 673 patients completed the follow-up, with 533 in fQRS group and 140 in non-fQRS group. The P wave duration in the fQRS group was longer than non-fQRS group [(92±21) vs (82±23)ms, P<0.01]. The left ventricular ejection fraction (LVEF) value in the fQRS group was lower than non-fQRS group (42%±22% vs 49%±15%, P<0.01) according to echocardiography results. The subgroup analysis with abnormal Q wave showed that compared with non-fQRS group, the left ventricular ejection fraction (LVEF) value in the group of fQRS was lower (38%±21% vs 50%±7%, P<0.01). There was statistically significant in the mortality of patients within follow-up period between the two groups (P<0.05), and the survival time in fQRS group was shorter than the non-fQRS group [(28.3±3.4) vs (30.5±1.5)months, P<0.01]. Conclusion: FQRS presence in body surface ECG of CHD patients with abnormal Q wave is a sign for increased risk of cardiovascular events, which can serve as an indicator to identify CHD patients at high risk of death.

Abstract
OBJECTIVE To investigate the prediction value of deceleration capacity of rate (DC) and GRACE risk score for cardiovascular events in AMI patients. METHODS Consecutive AMI patients with sinus rhythm hospitalized in our department during August 2012 to August 2013 were included in this prospective study. 24-hour ECG Holter monitoring was performed within 1 week, and the DC value was analyzed, GRACE risk score was acquired with the application of GRACE risk score calculator. Patients were followed up for more than 1 year and major adverse cardiac events (MACE) were obtained. Analysised the Kaplan Meier survival according to DC and GRACE score risk stratification respectively. RESULTS A total of 157 patients were enrolled in the study (average age: (58.9±12.7)years old). The average follow-up was (20.54±2.85) months. Mortality during follow-up was significantly higher in patients with DC>2.5 compared to patients with DC≤2.5 (P<0.01). In terms of early warning cardiac death, the area under ROC curve of DC risk stratification was 0.898 (95%CI 0.840-0.940, P<0.01), the sensitivity was 84.6%, and the specificity was 84.0%. The area under ROC curve of GRACE risk stratification was 0.786 (95%CI 0.714-0.847, P<0.01), the sensitivity was 84.6%, and the specificity was 74.3%. In terms of early warning cardiac adverse events, the ROC curve of DC was 0.747(95%CI 0.672-0.813, P<0.01), with the 90.0% sensitivity and 67.7% specificity. The GRACE risk stratification was 0.708 (95%CI 0.652-0.769, P<0.01), with the 63.3% sensitivity and 75.6% specificity. Subgroup analysis showed that mortality during follow-up was significantly higher in high risk patients than those with intermediate and low risk patients according to DC risk stratification in intermediate and low risk patients by GRACE risk stratification (P<0.01). CONCLUSION DC could predict cardiac death and MACE in patients with AMI. DC risk stratification is superior to GRACE risk score on outcome assessment in this AMI patient cohort.

Abstract
OBJECTIVE To observe the variation of central hemodynamics and peripheral arterial stiffness in different ages and to investigate the parameters of differential effects in younger individuals (≤60y) and older individuals (>60y). METHODS We conducted a population-based cross-sectional study in eight regions by random cluster sampling, from April to July 2014 in Beijing, China.Central hemodynamics and peripheral arterial stiffness parameters were determined in 861 healthy (372 male), normotensive individuals, aged 20 to 91(56±14) years.The main observed indexes were central systolic blood pressure (cSBP), arterial augmentation index (AI), augmentation pressure (AP), heart-ankle pulse wave velocity (haPWV) and brachial-ankle PWV (baPWV). Subjects were divided into six groups by 10 aged segment.Differences between groups and age tendency were observed. RESULTS The mean values of cSBP, AI, AP, haPWV and baPWV were (113±12) mmHg, (90±18)%, (-5±9) mmHg, (987±144) cm/s and (1 382±254) cm/s, respectively.cSBP, AI, AP, haPWV and baPWV increased with age (P<0.001). In average, cSBP, baPWV and haPWV increased 3 mmHg, 97 cm/s and 62 cm/s by additional 10 years, respectively.cSBP, AI and AP increased slowly after 60 years old, while haPWV and baPWV increased significantly with age (P<0.001). Stepwise regression analysis showed: cSBP was mainly relevant with mean arterial pressure(b=0.990, P<0.001), while baPWV and haPWV were relevant with age(b=8.858, 5.971; P<0.001). AI and AP were associated with height and rest heart rate (b=-0.676, -0.660 and b=-0.361, -0.341, P<0.001). Individuals were divided into two groups by age 60.The age-related changes in AI were significant in under 60-year-old; while the changes in baPWV were more prominent in over 60-year-old.However there was no significant difference in cSBP between two groups. CONCLUSIONS In healthy people, there are obvious differences of age tendency in central hemodynamics and peripheral arterial stiffness parameters.AI might be a good predictor of cardiovascular disease for early stage, especially for early coronary artery disease.

Abstract
OBJECTIVE To observe the efficacy and safety of bivalirudin use in Chinese patients with coronary heart disease (CHD) during the peri-percutaneous coronary intervention(PCI) period. METHODS A total of 3 271 patients who underwent PCI and received periprocedural bivalirudin treatment between July 2013 and October 2015 from 88 centers of China were involved in this study. The primary outcome was 30-day net adverse clinical events (NACE a composite of major adverse cardiac or cerebral events (MACE, all-cause death, reinfarction, urgent target vessel revascularization, or stroke) or bleeding), the secondary outcome was stent thrombosis at 30 days. RESULTS The mean age of enrolled patients was (65.12±12.44) years old, 27.4%(889/3 244) of them were female. Percent of stable coronary disease (SCD), non-ST segment elevation acute coronary syndrome (NSTE-ACS) and ST elevation myocardial infarction (STEMI) was 5.0%(162/3 248), 44.6%(1 450/3 248) and 50.4%(1 636/3 248) respectively. Radial access was performed in 89.5% (2 879/3 271) patients, and 9.7% (316/3 271) and 34.1% (1 115/3 271) patients also received ticagrelor and tirofiban medication. 69.3% (2 266/3 271) patients received post-procedural bivalirudin infusion, in which 46.3% (1 050/2 266) was treated at PCI-does, with a median duration of 2.5(1.0, 4.0) h. During the 30-day follow-up, NACE occurred in 3.45% (103/2 988) patients, the incidence of MACE, death was 2.17% (65/2 994) and 1.03% (31/3 017), respectively and bleeding events were recorded in 1.37% (41/2 996) patients. Four cases (0.13%) of stent thrombosis (3 acute stent thrombosis) were recorded. CONCLUSION Peri-PCI Bivalirudin use is safe and related with low bleeding risk in Chinese CHD patients.

Abstract
Aurora kinases have emerged as attractive targets for the development of novel anti-cancer agents. A combined study of molecular docking, pharmacophore modelling and 3D-QSAR was performed on a series of imidazo [1, 2-a] pyrazines as novel Aurora kinase inhibitors to gain insights into the structural determinants and their structure-activity relationship. An ensemble of conformations based on molecular docking was used for PHASE pharmacophore studies. The developed best-fitted pharmacophore model was validated by diverse chemotypes of Aurora A kinase inhibitors and was consistent with the structural requirements for the docked binding mechanism. Subsequently, the pharmacophore-based alignment was used to develop PHASE and comparative molecular similarity indices analysis (CoMSIA) 3D-QSAR models. The best CoMSIA model showed good statistics (q (2 )= 0.567, r (2 )= 0.992), and the predictive ability of the model was validated using an external test set of 13 compounds giving a satisfactory prediction ([Formula: see text]). The 3D contour maps provided insight into the binding mechanism and highlighted key structural features that are essential to the inhibitory activity. Based on the PHASE and CoMSIA 3D-QSAR results, a set of novel Aurora A inhibitors were designed that showed excellent potencies.

Abstract
Polo-like kinase 1 is an important and attractive oncological target that plays a key role in mitosis and cytokinesis. A combined pharmacophore- and docking-based virtual screening was performed to identify novel polo-like kinase 1 inhibitors. A total of 34 hit compounds were selected and tested in vitro, and some compounds showed inhibition of polo-like kinase 1 and human tumor cell growth. The most potent compound (66) inhibited polo-like kinase 1 with an IC(50) value of 6.99 μm. The docked binding models of two hit compounds were discussed in detail. These compounds contained novel chemical scaffolds and may be used as foundations for the development of novel classes of polo-like kinase 1 inhibitors.

Abstract
AIMS To avoid the misdiagnosis of prostate cancer (PCA), many patients receive repeated biopsies, despite receiving prior negative biopsies for PCA. Signal transduction and activators of transcription 3 (STAT3), a component of the JAK-STAT signaling pathway, can be activated by tyrosine phosphorylation as P-STAT3 and involved in the regulation of cellular growth, survival and oncogenesis. We aimed to assess the reliability of detecting PCA from the expression of P-STAT3 in prostate tissue previously designated as a negative biopsy. METHODS Prostate tissues were obtained from the biopsies of 52 patients with localized PCA as well as from the biopsies of 80 patients free of PCA. Expression of P-STAT3 in these specimens was examined by immunohistochemical staining (IHC) and used to distinguish tissue with PCA from tissue designated as benign during a biopsy procedure. RESULTS P-STAT3 staining intensities in all samples (initial negative biopsies, cancer positive cores and other negative cores from the same-batch biopsies) of PCA patients was significantly higher than that of benign patients (F = 23.664, P < 0.001). Analysis of the receiver operating characteristics (ROC) curve showed that the area under curve (AUC) for P-STAT3 staining was 0.785. When positive immuno-labeling of P-STAT3 in samples from initial biopsies was used as a marker for PCA, it showed relatively high sensitivity (80.8%) and specificity (76.3%). CONCLUSIONS IHC of P-STAT3 could be utilized to detect PCA patients with initial negative biopsies. As a result, it can be a potential adjunctive tool for current PCA diagnostic programs. P-STAT3 can predict the onset of PCA up to 40 months earlier than currently used diagnostic approaches.

Abstract
Polo-like kinase 1, an important enzyme with diverse biological actions in cell mitosis, is a promising target for developing novel anticancer drugs. A combined molecular docking, structure-based pharmacophore modeling and three-dimensional quantitative structure-activity relationship (3D-QSAR) study was performed on a set of 4,5-dihydro-1H-pyrazolo[4,3-h]quinazoline derivatives as PLK1 inhibitors. The common substructure, molecular docking and pharmacophore-based alignment were used to develop different 3D-QSAR models. The comparative molecular field analysis (CoMFA) and comparative molecule similarity indices analysis (CoMSIA) models gave statistically significant results. These models showed good q(2) and r(2) (pred) values and revealed a good response to test set validation. All of the structural insights obtained from the 3D-QSAR contour maps are consistent with the available crystal structure of PLK1. The contour maps obtained from the 3D-QSAR models in combination with the structure based pharmacophore model help to better interpret the structure-activity relationship. These satisfactory results may aid the design of novel PLK1 inhibitors. This is the first report on 3D-QSAR study of PLK1 inhibitors.

Abstract
According to a three-point pharmacophore for some uro-selective α(1) -adrenoceptor (AR) antagonists, a novel class of coumarin (=2H-1-benzopyran-2-one) derivatives have been successfully designed and synthesized with high efficacies for α(1) -AR. These synthesized coumarin derivatives exhibited high efficacies towards α(1) -AR in in vitro pharmacological assays. Compared with prazosin (pK(i) value of 8.77), among those coumarins, tolylpiperazine-substituted derivatives, 7 and 8, have comparable pK(i) values of 8.81 and 8.77, respectively. The trend in efficacies of these coumarin derivatives towards α(1A) -adrenoceptor was further rationalized by intensive molecular docking. Our work demonstrated that the designed coumarin derivatives can inhibit α(1) -AR in vitro. These findings will provide a guide for further studies of the medical therapy of benign prostatic hyperplasia (BPH).

Abstract
During their synthesis, many water-soluble proteins and nearly all membrane proteins transit through a protein-conducting channel in the membrane, the Sec translocon, from where they are inserted into the lipid bilayer. Increasing evidence indicates that folding of the nascent protein begins already within the ribosomal exit tunnel in a sequence- and environment-dependent fashion. To examine the effects of the translocon on the nascent-chain folding, we have calculated the potential of mean force for α-helix formation of a 10-alanine oligopeptide as a function of its position within the translocon channel. We find that the predominant conformational states, α-helical and extended, reflect those found for the peptide in water. However, the translocon, via its surface properties and its variable diameter, shifts the equilibrium in favor of the α-helical state. Thus, we suggest that the translocon facilitates not only the insertion of membrane proteins into the bilayer but also their folding.

Abstract
Carotenoid-binding protein (CBP) is the only key protein that has been characterized to be involved in yellow cocoon coloration of the domesticated silkworm (Bombyx mori). Gene structure and mRNA expression profiles of cbp along with UV-Vis spectrum profiles of carotenoids in silk glands were investigated among twelve strains to disclose their relationship with cocoon color. Yellow cocoon strains of B. mori contained two or three cbp gene types, which had different mRNA products with a longer form acting functionally to code CBP protein and the smaller one without exon 2. The structures of cbp were different among the green cocoon strains with the mRNA product lacking exon 2. Only one cbp gene structure existed in white cocoon strains of B. mori, which produced the mRNA product free of exon 2. A newly identified intron 1 sequence of cbp gene in this study may have cocoon color-specificity among strains. The UV-Vis spectrum profiles of carotenoids in the yellow cocoon strains' silk glands were significantly different from those in the green cocoon strains and white cocoon strains.Together, it can be concluded that the gene structure and expression profile of cbp was closely linked to cocoon colors of B. mori.

Abstract
The InhA-related enoyl-ACP reductase, an enzyme involved in fatty acid synthesis, is one of the best validated targets for the development of anti-tubercular agents. However, the majority of isoniazid (INH)-resistant clinical strains are observed mainly due to the emergence of KatG mutants that do not form an INH-NAD adduct. Thus compounds that directly inhibit InhA avoiding activation by KatG would be promising candidates for combating MDR-TB. Herein, some predominant examples of InhA direct inhibitors recently developed are reviewed and special attention is paid to 3D-structures of InhA in drug design process.

Abstract
We investigate the transport of a single ligand L, between two macroscopic baths with different concentrations of L, by a simple membrane system. The center of this system is a very small volume V that might contain N = 0, 1, 2,... molecules of L. Access to V from either bath is by means of a single binding site for L. The steady-state properties of this simple system are studied exactly by a discrete-N master-equation approach. It is found that the mean concentration of L in V, c = N/V, is not a significant quantity either kinetically or thermodynamically. Further, the chemical potential of L in V is not defined and hence the overall thermodynamic force on L between the two baths cannot be subdivided at V. In fact, because V is small, the transport system must be treated as an indivisible system with interdependent parts. In the limit when V and N are very large, V becomes in effect a third macroscopic bath and two well-defined transport subsystems emerge (between V and either bath).
