Abstract
Objective: To investigate the impact of metabolic syndrome (MS) and its individual components on long-term prognosis of patients undergoing percutaneous coronary intervention(PCI). Methods: Patients who underwent PCI in Fuwai Hospital in 2013 were enrolled and divided to two groups: with MS and without MS. The primary endpoint of 2-year follow-up was major adverse cardiovascular events (MACE), including death, myocardial infarction, and repeat revascularization. Results: Of the 10 422 PCI patients, there were 5 656 (54.27%) without MS and 4 766 (45.73%) with MS. Patients in the MS group were younger, tended to be male and had more comorbidities. There were no significant differences between the two groups in the proportion of drug-coated stents and the success rate of interventional therapy. The 2-year follow-up showed that the incidence of MACE in the MS group was significantly higher than that in the MS-free group (12.0% vs 10.0%, P<0.001), which was mainly due to the significantly higher revascularization rate in the MS group than in the non-MS group (9.5% vs 7.9%, P=0.003). Cox's regression analysis showed that MS was an independent risk factor for MACE. In MS component analysis, abnormal glucose metabolism was an independent risk factor for MACE events. Conclusions: Among the patients undergoing PCI, the incidence of MACE in patients with MS is significantly higher than that in patients without MS, and MS was an independent risk factor for MACE. In addition, hyperglycemia is an independent predictor for MACE.

Abstract
Objective: To study the clinical and pathologic factors of papillary thyroid microcarcinoma (PTMC) and its significance as a histopathologic subtype of papillary thyroid carcinoma (PTC). Methods: A retrospective study of 719 patients with non-high-risk PTMC who underwent surgery for the first time in the Peking University People's Hospital from January 2007 to June 2019 was conducted, the relationship between clinicopathologic factors and lymph node metastasis, and the expression of four tumor markers CK19, HMBE1, Galectin-3 and CD56 by immunohistochemistry were evaluated. Some comparisons were made with PTC. Results: The peak patients' age was 40-49 years for both non-high-risk PTMC and PTC; the lymph node metastasis rate was higher in the 30-39 years age group than the 50-59 years age group (P<0.05); the lymph nodes metastasis rate was significantly higher for multiple lesions than for single lesion (P<0.05). Lymph node metastasis rate of PTMC with capsular invasion was significantly higher than those without (P<0.05). There was no significant correlation between lymph node metastasis of PTMC and patients' gender, tumor location, tumor size, and lymphocytic thyroiditis. The expression rates of CK19, HMBE1 and Galectin-3 both in PTMC and PTC were 100%, and the expression rates of CD56 were 25.6% (85/332) and 20.0% (70/350) respectively. Conclusion: As the main pathologic subtype of PTC, a variety of clinicopathologic factors of PTMC are related to lymph node metastasis, and it is highly recommended to pay close attention to PTMC. The expression of tumor marker CD56 alone cannot be used as a basis to exclude PTMC and PTC.

Abstract
Objective: To assess the accuracy of photoscreening for detecting refractive amblyopia risk factors (ARFs) in Chinese preschool children aged 4 to 5 years. Methods: A cross-sectional study. Comprehensive ocular examinations were conducted for preschool children in Nanjing, China from September to December, 2016. Photoscreening (Plusoptix A12C) was applied for refractive screening without cycloplegia. Voluntary children and children suspected of eyes abnormalities received cycloplegic retinoscopy (CR). Results of photoscreening and CR were compared using Wilcoxon signed rank test, and Bland-Altman plot were used to assess the agreement between the photoscreener and CR. According to the updated preschool vision screening guidelines from American Association for Pediatric Ophthalmology and Strabismus (AAPOS) in 2013, CR was adopted for identifying children with ARFs, which was considered as a golden standard. Based on the golden standard, the accuracy of 5 sets of referral criteria (including sensitivity standard, Matta/Silbert standard, AAPOS2013 standard, Alaska Blind Child Discovery standard, specificity standard) for photoscreener were tested. Receiver operating characteristics curves were constructed applied to evaluate the quality of the photoscreener in refractive ARFs detection and to find probably the best cut-off points. Results: In total, 1 986 children [mean age, (4.57±0.29) years] received comprehensive examinations, including 1 084 boys and 902 girls. The test ability of photoscreening was 99.04% (1 967/1 986) in the preschool children, and 96.56%(1 827/1 892) of the children got a reliable result within three screening attempts. In 538 children who had data of CR, refractive error of one child exceeded the upper limit of the photoscreener value setting, which was directly categorized as hyperopia, so in the end, 537 children were included to analyze the comparison between the two tests. The measurement values of photoscreening were lower than those of CR in sphere, cylinder and spherical equivalent [(0.75 (0.50, 1.25) D vs. 1.25 (1.00, 1.75) D, Z=-10.36, P<0.01; -0.50 (-0.75, -0.25) D vs. -0.25 (-0.75, 0.00) D, Z=-11.10, P<0.01; 0.63 (0.38, 0.88) D vs. 1.00 (0.75, 1.50) D, Z=-13.33, P<0.01]. The 95% limit of agreement cover rates between the photoscreening and CR in sphere, cylinder and spherical equivalent was 96.28% (517/537), 95.34% (512/537) and 96.65% (519/537), respectively. Based on the golden standard, 47 (8.74%) children had refractive ARFs, and the range of sensitivity, specificity, Youden index, positive predictive values and negative predictive values for detecting refractive ARFs of the 5 common used referral criteria was from 63.83% to 97.87%, from 53.36% to 97.56%, from 0.51 to 0.80, from 16.73% to 74.51% and from 96.57% to 99.62%, respectively. Considering particular refractive ARFs on the basis of the receiver operating characteristic curves, the optimal cut-off point for astigmatism was set at 1.38 D. Conclusion: Photoscreening could be an applicable tool to detect refractive ARFs in preschool children. (Chin J Ophthalmol, 2020, 56: 189-196).

Abstract
Objective: To explore the duration of intestinal detoxification and its related factors infected with Norovirus, and to provide scientific evidences for the prevention and control of acute gastroenteritis caused by Norovirus in the future. Methods: Follow up and sampling program on 115 employees in a restaurant outbreak of Norovirus in Chengdu in 2017 was carried out. Anal swab was collected every 3 d or 7 d for nucleic acid detection, and the experimental results were statistically analyzed. Results: The positive rates of Norovirus in restaurant employee were 14.78%, 7.89%, 3.51% and 0.88% on the 7(th), 11(th), 17(th) and 24(th) day, respectively. During the follow-up period, the positive rates of Norovirus decreased as time increased. The positive rate of all employees was up to 14.78% on the 7(th) day. The positive rates had no significant difference between different sex and between different types of work. The duration of detoxification averaged 14.94 days and the maximum of detoxification time was on 28 days. The detoxification period of treatment case was shorter than that of asymptomatic carriers. Conclusions: There were asymptomatic carriers in restaurant employees during the outbreak of Norovirus that their role as a source of infection in the transmission of Norovirus should not be neglected. In the treatment of the epidemic, we should strengthen the sampling and testing of practitioners, and strictly implement isolation measures for positive detection.

Abstract
Objective: To compare the clinical characteristics and long-term prognosis between male and female patients with premature coronary artery disease (PCAD) post coronary intervention, and analyse the risk factors of major adverse cardio-cerebrovascular events (MACCE) and bleeding events. Methods: This was a prospective single-center observational study. From January 2013 to December 2013, 4 744 patients diagnosed as PCAD and treated with percutaneous coronary intervention (PCI) in Fuwai Hospital were enrolled. The general clinical data, laboratory results and interventional treatment data of all patients were collected, and patients were followed up for 2 years after PCI and the incidence of events including MACCE and bleeding was analyzed. The baseline data and clinical events of PCAD patients of different genders were compared. Survival curves were estimated by Kaplan-Meier method. Univariate and multivariate Cox regression were used to analyze whether gender was an influencing factor of different clinical events of PCAD patients within 2 years after PCI, and other relevant influencing factors of MACCE and bleeding events. Results: Among the 4 744 PCAD patients included, there were 3 390 (71.5%) male aged (47.0±5.4) years old and 1 354 (28.5%) female aged (57.0±5.8) years old. Compared with female patients, male patients had higher body mass index, higher proportion of hyperlipidemia, smoking, myocardial infarction, previous PCI, preoperative estimated glomerular filtration rate, ST-segment elevation myocardial infarction, radial artery approach, intravenous ultrasound use and chronic occlusive lesions (all P<0.05). Age, left ventricular ejection fraction, prevalence of hypertension, diabetes mellitus, past stroke history, non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and the use of calcium channel blockers were lower in male patients than in female patients (all P<0.05). The 2-year follow-up results showed that the incidence of BARC type 1 hemorrhage was significantly higher in female patients than in male patients (6.9%(92/1 343) vs. 3.7%(126/3 378), P<0.001); however, the incidence of MACCE, all-cause death, cardiac death, recurrent myocardial infarction, revascularization (target vessel revascularization and target lesion revascularization), stent thrombosis, stroke and BARC type 2-5 hemorrhage were similar between the two groups (all P>0.05). Multivariate Cox regression analysis showed that gender was an independent risk factor for BARC type 1 bleeding in PCAD patients (HR=2.180, 95%CI 1.392-3.416, P<0.001), but it was not an independent risk factor for MACCE and BARC type 2-5 bleeding(all P>0.05). Hyperlipidemia, preoperative SYNTAX score, multivessel lesions and NSTE-ACS were the independent risk factors for MACCE in PCAD patients with PCI (the HRs(95%CI) were 1.289(1.052-1.580), 1.030(1.019-1.042), 1.758(1.365-2.264), 1.264(1.040-1.537), respectively); gender (HR=1.579, 95%CI 1.085-2.297, P=0.017), hyperlipidemia (HR=1.305, 95%CI 1.005-1.695, P=0.046), anticoagulant drugs including low molecular weight heparin (HR=1.321, 95%CI 1.002-1.741, P=0.048) or sulfonate(HR=1.659, 95%CI 1.198-2.298, P=0.002) were the independent risk factors for bleeding events. Conclusions: There are differences in clinical and coronary artery lesion characteristics between different genders in patients with PCAD. The incidence of minor bleeding is significantly higher in female PCAD patients than in male PCAD patients. Hyperlipidemia, preoperative SYNTAX score, multivessel lesions and NSTE-ACS are the independent risk factors for MACCE, and gender, hyperlipidemia, anticoagulant drugs including low molecular weight heparin or sulfonate are the independent risk factors for bleeding events in patients with PCAD.

Abstract
Abstract
Background
Prediction of in-hospital bleeding is critical for clinical decision making for acute myocardial infarction (AMI) patients undergoing percutaneous coronary intervention (PCI). Machine learning methods can automatically select the combination of the important features and learn their underlying relationship with the outcome.
Objective
We aim to evaluate the predictive value of machine learning methods to predict in-hospital bleeding for AMI patients.
Methods
We used data from the multicenter China Acute Myocardial Infarction (CAMI) registry. We randomly partitioned the cohort into derivation set (75%) and validation set (25%). Using data from the derivation set, we applied a state-of-art machine learning algorithm, XGBoost, to automatically select features from 106 candidate variables and train a risk prediction model to predict in-hospital bleeding (BARC 3, 5 definition).
Results
16736 AMI patients who underwent PCI were consecutively included in the analysis, while 70 (0.42%) patients had in-hospital bleeding followed the BARC 3,5 definition of bleeding. Fifty-nine features were automatically selected from the candidate features and were used to construct the prediction model. The area under the curve (AUC) of the XGBoost model was 0.816 (95% CI: 0.745–0.887) on the validation set, while AUC of the CRUSADE risk score was 0.723 (95% CI: 0.619–0.828).

Abstract
Abstract
Background
Hypoalbuminemia was reported to be associated with poor prognosis in severe diseases. Triple-vessel coronary artery disease (TVD) has high risk of death. We aimed to evaluate the predictive value of hypoalbuminemia in TVD patients.
Methods
A total of 8,943 consecutive TVD patients were enrolled from April 2004 to February 2011. The primary endpoint was all-cause death and the secondary endpoints were major adverse cardiovascular and cerebrovascular events (MACCE; a composite of all-cause death, myocardial infarction or stroke). Patients were divided into two groups according to normal serum albumin level (<4.0 g/dL and ≥4.0 g/dL).
Results
During the median of follow-up 7.5 years, 1365 deaths and 2354 MACCE occurred. Multivariate Cox regression indicated that hypoalbuminaemia (<4.0 g/dL) was an independent predictor of all-cause death (HR 1.30, 95% CI 1.14–1.50, P<0.001) and MACCE (HR 1.19, 95% CI 1.07–1.32, P<0.001). Adjustment of the all-cause death risk estimated by albumin improved the predictive value of SYNTAX score (AUC from 0.585 to 0.602, P=0.002; IDI=0.005, P<0.001; NRI=0.205, P<0.001). For SYNTAX II score, improvement was shown for NRI and IDI but not for AUC (SYNTAX II for PCI: IDI=0.003, P<0.001; NRI=0.205, P<0.001; AUC from 0.711 to 0.713, P=0.257; SYNTAX II for CABG: IDI=0.002, P<0.001; NRI=0.205, P<0.001; AUC from 0.696 to 0.698, P=0.120).
Predictive value for all-cause death using the AUC, NRI and IDI AUC (95% CI) P value NRI (95% CI) P value IDI (95% CI) P value SYNTAX 0.585 (0.568–0.602) Ref.

Conclusions
For TVD patients, hypoalbuminaemia was a strong independent prognostic factor for long-term outcomes of death and MACCE. Albumin improved the prediction of death with the SYNTAX score and the SYNTAX II score.

Abstract
Idiosyncratic (unpredictable) drug-induced liver injury (iDILI) is one of the most challenging liver diseases encountered by hepatologists due to its diverse clinical and pathological manifestations and lack of specific diagnostic markers. An increasing awareness of iDILI diagnosis and carefully excluding liver damage induced by other causes is the key to a proper diagnosis of iDILI. However, delayed diagnosis, inappropriate monitor and care leads to serious clinical consequences, such as acute liver failure or even liver-related death. In addition, there is presently no effective treatment for iDILI. Herein, we presented the main recommendations of the recent EASL published first DILI guidelines into Chinese language to facilitate liver disease authors and health workers to understand the latest research progress of DILI.

Abstract
Objective: To evaluate the effect of ABO blood groups on long-term outcome of stable coronary artery disease (CAD) after percutaneous coronary intervention (PCI). Methods: A total of 4 272 patients with stable coronary artery disease and received PCI were consecutively enrolled from January to December 2013 and followed up for 2 years. Patients were divided into O group and non-O group according to their ABO groups. Multivariable COX regression was used to evaluated the relationship between ABO blood groups and prognosis of CAD. The endpoints included all-cause death, cardiac death, myocardial infarction(MI), revascularization, and stroke. Results: There were 1 302 patients in O group and 2 970 patients in non-O group. ABO blood group was not associated with age, sex and blood pressure (P>0.05). The comorbidity rate of hypertension, diabetes mellitus, smoking, family history, previous MI, previous cerebrovascular disease, previous PCI and left ventricular ejection fraction were similar between the two groups (P>0.05). Total cholesterol, low density lipid cholesterol level were significantly higher in non-O group compared with O group [(4.2±1.1)mmol/L vs (4.1±1.1)mmol/L, P=0.027; (2.5±0.9)mmol/L vs (2.4±0.9) mmol/L, P=0.025], while high density lipid cholesterol level was significantly lower[(1.04±0.26) mmol/L vs (1.06±0.28) mmol/L, P=0.035]. As to angiographic results, non-O blood group was not related to the severity of coronary atherosclerosis assessed by SYNTAX score(P=0.277). More cardiac death occurred in non-O group compared with that in O group [21 (0.7%) vs 2(0.1%)] during 2-year follow-up. After adjusted for confounding factors, multivariable COX regression revealed that non-O blood type was not associated with increased cardiac death [HR (95%CI)=7.30(0.97-55.09), P=0.054]. Conclusion: Non-O blood group is associated with 2-year cardiac death in patients with stable coronary artery disease who received PCI, but it is not an independent risk factor for cardiac death.

Abstract
The Ca2+ induced Spontaneous Oscillatory Contraction (Ca-SPOC) of cardiac myofibrils oscillate with a period similar to resting heartbeat of several animal species, and its auto-oscillatory properties set the basic rhythm of cardiac contraction. To explain the dynamics of Ca-SPOC, the present paper constructs a novel chemical kinetical model based upon the cooperative behavior between the two heads of myosin II dimer, also considering the reaction-diffusion effect of ATP inside myocardial fibers. The simulation results show that the concentration of ATP inside myocardial fibers oscillates over time under some special conditions, together with the proportions of myosin II dimers in different states periodically changing with time, which contributes to produce the sustained oscillations of contractive tension. These results indicate that the SPOC of muscles may be partly due to chemical oscillation involved in the actomyosin ATPase cycle, which has been ignored by the previous theoretical studies.

Abstract
Abstract Objective To study the structure and differences of bacterial communities in different soils, and to explore the effectiveness of 16S rRNA sequencing in identification of different soil. Methods Soil samples from 7 places in Shanghai were collected, then bacterial genomic DNA were extracted from them. The fragments of hypervariable region from 16S rRNA sequences were sequenced with high-throughput sequencing techniques. The results were quantified or visualized with bioinformatics software. The differences in diversity and abundance among the three kinds of bacterial communities in soil samples from grassland, forests and beaches were compared and analyzed. Results The statistical differences that existed among the alpha diversity indexes of bacterial communities in soil samples of grassland, forests and beaches had statistical significance. The relative abundance and diversity of bacterial communities in these three kinds of soil were significantly different. Grassland soil had higher Acidobacteria abundance, forest soil had higher Proteobacteria abundance, beach soil had higher Actinobacteria abundance. However, the differences in soil bacterial communities in artificial grasslands, natural grasslands and industrial district grasslands did not have statistical significance. Conclusion 16S rRNA sequencing can effectively distinguish different soils. This method may be able to provide clues for first crime scene inference in criminal cases.

Abstract
Objective: To investigate the long-term prognosis of Second generation drug-eluting stents(G2-DES) in diabetic mellitus(DM) and non-DM patients. Methods: Patients with coronary heart disease(CHD) in Fuwai Hospital from January 2013 to December 2013 who had exclusively G2-DES implantation, were consecutively included the follow-up period was 2 years. Results: A total of 6 094 patients with CHD were implanted with G2-DES, of which 1 862 patients with DM, and 4 232 patients without DM.The proportion of DM patients receiving G2-DES implantation with the following characteristics: advanced age, female, hypertension, hyperlipidemia, history of previous stroke, history of peripheral artery disease, previous history of PCI, and with triple vessel, high preoperative Syntax score, high number of target lesions, B2 or C type lesions, severe calcification lesions, and chronic occlusive disease were significantly higher than those of non-DM patients(P<0.05). The incidence of major adverse cardiac and cerebral vascular events(MACCE), target vascular revascularization(TVR) and target lesion revascularization(TLR) were higher in DM patients than in non-DM patients during 2 year's follow-up(P<0.05). The univariate COX regression analysis showed that diabetes was risk factor for MACCE in patients with CHD implanting G2-DES(HR=1.241, 95%CI: 1.053-1.463, P=0.010). However, multivariable COX analysis showed that DM was not an independent risk factor for MACCE in CHD patients with G2-DES(HR=1.125, 95%CI: 0.952-1.330, P=0.167). While age, female, preoperative Syntex score, triple vessel, B2 or C lesion were independent risk factors for poor clinical prognosis in CHD patients with G2-DES. Conclusions: (1) CHD patients with DM often accompany more clinical risk factors and complicated coronary lesions; (2) the incidence of MACCE, TVR and TLR in DM patients is significantly higher than non-DM patients with G2-DES during the 2 year's follow-up; (3) after multivariate adjustment, DM is not an independent risk factor for poor clinical prognosis in CHD patients with G2-DES, while traditional risk factors and complex coronary lesions are independent risk factors for poor clinical prognosis.

Abstract
Objective: Patients with acute coronary syndrome due to multivessel disease (MVD) were at the highest risk of adverse cardiovascular events. Neutrophil to lymphocyte ratio (NLR) was proposed as a marker of cardiovascular risk. Present study evaluated the independent predictive value of NLR for acute myocardial infarction (AMI) patients with MVD. Methods: AMI patients with MVD (n=1 433) underwent percutaneous coronary intervention (PCI) between January 2013 and December 2013 were followed up for 2 years. Patients were divided into 2 sub-groups based on an optimal cut off value of NLR to predict 2-year all-cause mortality. The primary endpoint was all-cause death. The secondary endpoint was long-term major adverse cardiovascular and cerebrovascular events (MACCE). Results: By receiver operating characteristics curve analysis, the optimal cut-off value of admission NLR to predict 2-year all-cause mortality was 3.39 (area under the curve 0.765, sensitivity 71%, specificity 73%). The high NLR group(n=396) had higher prevalence of prior myocardial infarction, prior PCI and intra-aortic balloon pump use (IABP)(P<0.01). Compared to the low NLR group (n=1 037), patients in the high NLR group were older, had higher level of neutrophil count and high-sensitivity C-reactive protein (hs-CRP) (P<0.001), but lower level of lymphocyte count, estimated glomerular filtration rate (eGFR) and ejection fraction (P<0.001). During the follow-up period, rate of long-term all-cause death was significantly higher in the high NLR group than in the low NLR group (5.1% (20/396) vs. 0.8% (8/1 037), P<0.001). Cardiac death (4.0% (16/396) vs. 0.7% (7/1 037), P<0.001) and MACCE (21.7% (86/396) vs. 12.6% (131/1 037), P<0.001) were also significantly higher in the high NLR group than in the low NLR group. Multivariate Cox analysis showed that NLR ≥ 3.39 was determined as an independent predictor of 2-year all-cause mortality (HR=3.23, 95%CI 1.38-7.54, P=0.007) and MACCE (HR=1.58, 95%CI 1.19-2.10, P=0.002) in this patient cohort after adjusting for other risk factors. Correlation analysis showed that the NLR was positively correlated with hs-CRP levels (r=0.241, P<0.001). Conclusion: Our study demonstrates that admission NLR ≥ 3.39 is an independent predictor of long term all cause death and MACCE in AMI patients with MVD post PCI.

Abstract
Objective: To investigate the impact of coronary lesion calcification on the long-term outcome of patients with coronary heart disease after percutaneous coronary intervention. Methods: In this prospective observational study, a total of 10 119 consecutive patients with coronary heart disease undergoing percutaneous coronary intervention from January 1 to December 31, 2 103 in our hospital were enrolled. The patients were divided into non/mild calcification group (8 268 cases) and moderate/severe calcification group (1 851 cases) according to the angiographic results. The primary endpoint was one-year major adverse cardiovascular events (MACE), including all-cause death, myocardial infarction, and target vessel revascularization. Results: The patients were (58.3±10.3) years old, and there were 2 355 females (23.3%). Compared with non/mild calcification group, patients in the moderate/severe calcification group were older ((60.0±10.6) years vs. (57.9±10.2) years, P<0.01), and had higher proportion of female (25.4% (470/1 851) vs. 22.8% (1 885/8 268), P=0.02), debates (33.9% (628/1 851) vs. 29.0% (2 399/8 268), P<0.01), hypertension (68.0% (1 259/1 851) vs. 63.7% (5 264/8 268), P<0.01), coronary artery bypass grafting (4.6% (85/1 851) vs. 3.2% (268/8 268), P<0.01), stroke (12.6% (233/1 851) vs. 10.4% (861/8 268), P=0.01), and renal dysfunction (6.2% (115/1 851) vs. 3.7% (303/8 268), P<0.01). Compared with non/mild calcification group, patients in themoderate/severe calcification group experienced longer procedure time (37 (24, 61) min vs. 27 (17,40) min, P<0.01) and stent length was longer (32 (23,48) mm vs. 27 (18,38) mm, P<0.01), and percent of rotational atherectomy was higher (2.56%(57/2 229) vs. 0.03% (3/11 930), P<0.01). One-year follow-up results showed that MACE (7.5% (139/1 846) vs. 4.9% (402/8 243), P<0.01), all-cause death (1.0% (19/1 846) vs. 0.6% (49/8 243), P=0.04), myocardial infarction (2.2% (41/1 846) vs. 1.4% (114/8 243), P=0.01), and target vessel revascularization (5.0% (92/1 846) vs. 3.2% (266/8 243), P<0.01) were all significantly higher in moderate/severe calcification group than in non/mild group. Multivariate Cox regression analysis showed that moderate/severe calcification was an independent predictor of MACE at one-year after the procedure (HR=1.41, 95%CI 1.16-1.72, P<0.01). Conclusion: Moderate/severe calcification in coronary lesion is an independent predictor of long-term poor prognosis in coronary heart disease patients undergoing percutaneous coronary intervention.

Abstract
Objective: To explore the clinical effects of adjacent fasciocutaneous flaps in repairing small wounds with bone or steel plate exposure in anterior tibia. Methods: Twelve patients with small wounds of bone or steel plate exposure in anterior tibia covering area of 2 cm×2 cm to 5 cm×3 cm were admitted to our unit from January 2014 to December 2016. A circular or elliptical adjacent fasciocutaneous flap was designed on the normal skin located at the inside or outside of the wound according to the size of wound after thorough debridement. The pedicle of the flap was located at the proximal end and transferred through the subcutaneous tunnel to cover the wound. The sizes of flaps were 3 cm×3 cm to 6 cm×4 cm. Flaps were fixed with interrupted sutures and drainage rubber sheets were placed under the flaps. The drainage rubber sheets were removed within 24 to 48 hours. The donor area was repaired by medium-thickness skin graft collected from homolateral outer thigh. Results: All the flaps of 9 patients survived. Two patients had necrosis at the distal end of the flaps and were cured by changing dressing. One patient had tension blisters on the flap and was cured by removing blisters and improving microcirculation. All patients were followed up for 3 months, and the flaps were good in blood supply, appearance, and color, with hypaesthesia. Conclusions: Repair of small wounds with bone or steel plate exposure in anterior tibia by adjacent fasciocutaneous flap is simple in surgical procedure and does not damage the well-known blood vessels, and the appearance, texture, and thickness of flaps are close to the skin of anterior tibia region. It is a good choice for repairing this kind of wounds and worth promoting in clinic.

Abstract
Objective: To improve the diagnostic quality of hepatolenticular degeneration by summarizing the clinicopathological features. Methods: A retrospective analysis of 21 cases that were diagnosed as hepatolenticular degeneration with liver biopsy in our hospital from January 2013 to August 2018 was reviewed, and then their clinicopathologic features were analyzed. The pathomorphological differences between liver biopsy and liver biopsy after transplantation, and the relationship between histopathological patterns and biopsy types and clinical indicators were analyzed by Fisher's exact test. Results: Of the 21 patients with hepatolenticular degeneration, 10 patients had liver biopsy, and 11 patients underwent liver biopsy after liver transplantation. Among them, four cases were presented as simple fatty liver pattern (19.0%, 4/21), eight cases as steatohepatitis pattern (38.1%, 8/21), four cases as inflammatory necrosis without cirrhosis pattern (19.0%, 4/21), and five cases as inflammatory necrosis with cirrhosis pattern (23.9%, 5/21). Twelve cases had copper deposition in the liver (57.1%, 12/21), and the pattern of copper distribution in the liver was uneven. Conclusion: A clinicalpathological features of hepatolenticular degeneration mainly manifests in four patterns, but lack characteristic changes. Hence, comprehensive judgment should rely on clinical history, laboratory examination, genetic test results and liver histopathological changes.

Abstract
Objective: To investigate the relationship between thrombolysis in myocardial infarction risk index(TRI) and the severity of coronary artery lesions and long-term outcome in acute myocardial infarction(AMI) patients undergoing percutaneous coronary intervention(PCI). Methods: A total of 1 663 consecutive AMI patients undergoing PCI between January and December 2013 in Fuwai hospital were prospectively included in this study. The severity of coronary artery lesions was evaluated using the SYNTAX score. Receiver operating characteristic(ROC) curve was used to analyze the optimal cut-off value of TRI on predicting all-cause mortality at 2 years after PCI.The patients were divided into 2 groups based on the optimal cut-off value of TRI:high TRI group (TRI ≥ 23.05, 465 cases) and low TRI group(TRI<23.05, 1 198 cases). Multivariate logistic regression analyses were used for determining the relationship between TRI and SYNTAX scores≥33. A multivariate Cox regression analyses was used to identify the influence factors of long-term outcome after PCI. Results: SYNTAX score was higher in high TRI group than in low TRI group (13.00(7.00, 20.50) vs.10.25(7.00, 17.00), P<0.001). TRI was independently associated with SYNTAX score ≥ 33 (OR=1.09,95% CI 1.03-1.16, P=0.004). After the 2 years follow-up, rates of all-cause death (4.1% (19/465) vs. 0.3% (4/1 198) , P<0.001), cardiac death (2.6% (12/465) vs. 0.2% (2/1 198) , P< 0.001) and stent thrombosis (1.7% (8/465) vs. 0.5% (6/1 198) , P=0.015) were all significantly higher in high TRI group than in low TRI group. Multivariate Cox regression analyses showed that TRI≥ 23.05 was an independent risk factor of all-cause death (HR=5.22, 95%CI 1.63-16.72, P=0.005), cardiac death (HR=8.48, 95%CI 1.75-41.07, P=0.008) and stent thrombosis(HR=3.87, 95%CI 1.32-11.41, P=0.014) at 2 years after PCI in AMI patients, but which was not the independent risk factor of major adverse cardiovascular and cerebrovascular events (HR=0.96, 95%CI 0.69-1.36, P=0.834) .The area under ROC curve of TRI ≥ 23.05 on predicting 2 years all-cause mortality in AMI patients undergoing PCI was 0.803(95%CI 0.711-0.894, P<0.001). Conclusions: TRI is independently associated with SYNTAX score ≥ 33. TRI is also an independent risk factor of 2 years all-cause death, cardiac death and stent thrombosis in AMI patients undergoing PCI.

Abstract
Forensic microorganism is one of the hotspots of forensic science research. Due to its conservatism and specificity, the 16S rRNA gene is found to be an ideal marker for forensic identification. With the rapid development of high throughput sequencing technology, the research on microorganisms has been gradually applied to many fields such as environment and health care. In the field of forensic science, the results of forensic microbiology research, represented by 16S rRNA gene sequencing, are also gradually applied to forensic practice, such as biological samples identification, individual identification, postmortem interval estimation, and regional inference, which not only provide clues for the investigation of cases but also complement and assist traditional methods. This paper describes the research methods and related sequencing technologies of 16S rRNA gene sequencing, summarizes its research progress, and discusses the application value and potential of 16S rRNA in forensic science.

Abstract
Objective: To investigate the influence of change in blood pressure status from childhood to adulthood on renal damage. Methods: Data were obtained from Beijing Blood Pressure Cohort initiated from 1987. 3 198 children and adolescents aged 6-18 years from 6 primary and 6 middle schools in Chaoyang, Xicheng and Haidian Districts of Beijing were enrolled at baseline by using a cluster random sampling method, and 1 222 participants were followed up during 2010-2012. The measurements included weight, height, and blood pressure at baseline and microalbumin, serum creatinine, cystatin C and blood pressure at follow-up. Based on blood pressure status in childhood and adulthood, the participants were divided into four groups: participants with normal blood pressure in both childhood and adulthood, participants with elevated blood pressure in childhood but normal blood pressure in adulthood, participants with normal blood pressure in childhood but elevated blood pressure in adulthood, and participants with elevated blood pressure in both childhood and adulthood. Multivariate linear regression model was used to investigate the association of change in blood pressure from childhood to adulthood on renal dysfunction. Results: The prevalence of elevated blood pressure in childhood and adulthood was 17.9% and 39.9%, respectively. The P(50) (P(25)-P(75)) of microalbumin was 5.7(3.0-12.0) mg/L, and the concentration of eGFR and cystatin C were (118.0±19.8)% and (0.734±0.184)mg/L, respectively. With adjustment for sex, baseline age and follow-up years, compared with participants with persistently normal blood pressure from childhood to adulthood, participants with normal blood pressure in childhood but elevated blood pressure in adulthood had significantly higher levels of microalbumin (β=0.502, 95%CI: 0.320-0.684) and cystatin C (β=0.049, 95%CI: 0.025-0.073). After adjustment for sex, baseline age, follow-up duration, and adult BMI, smoking and drinking, participants with normal blood pressure in childhood and elevated blood pressure in adulthood had higher levels of adult urine microalbumin (β=0.322, 95%CI: 0.128-0.516) and cystatin C (β=0.032, 95%CI:0.007-0.057). Conclusion: An increase in blood pressure during childhood and adulthood has an adverse impact on renal functional damage in adulthood. These findings underscore the importance of maintaining normal blood pressure during life course to prevent the development of chronic kidney disease.

Abstract
Asthma is a respiratory disease that affects people of all walks of life, and is a hotspot of continuous research, with significant manpower and resources invested in its study. Airway remodeling is an important associated pathological change, and a mark of the irreversible damage produced by asthma. It involves compositional and functional changes in the cells of the airway walls, leading to reversible structural changes, and complicating treatment. Airway remodeling is mediated by different inflammatory pathways which have been targeted for treatment, with good results. However, given its complexity, systematic study of the pathogenesis of airway remodeling is still needed, and additional targeted therapies are necessary. Macrolide drugs, such as erythromycin, azithromycin, and clarithromycin, have antibacterial effects and also influence the cytokine secretion of macrophages and T-lymphocytes. They have direct effects on a variety of cytokines, inhibiting inflammation and reducing airway reactivity. In this study, we investigated the protective effect of azithromycin on airway remodeling through the phosphoinositol-3 kinase/Akt/mechanistic target of rapamycin kinase/hypoxia-inducible factor 1α (HIF-1α)/vascular endothelial growth factor (VEGF) pathway. We observed that a long course of azithromycin could significantly reduce airway reactivity and ovalbulmin-induced pathological alterations in asthmatic mice. Gene expression analysis confirmed that HIF-1α and VEGF were significantly down-regulated following a long course of azithromycin administration.
