Abstract
Objective: To explore the effectiveness, safety and cost between urinary follicle stimulating hormone (uFSH) and recombinant follicle stimulating hormone (rFSH) in controlled ovarian stimulation (COS) in China. Methods: Data were collected from 16 reproductive centers in China covering oocytes collection time from May 1, 2015 to June 30, 2018. Eligible patients were over 18 years old, adopting COS with uFSH (uFSH group) or rFSH (rFSH group) as start gonadotropins (Gn), and using in vitro fertilization (IVF) and (or) intracytoplasmic sperm injection for fertilisation, excluding frozen embryo recovery cycle. Generalised estimating equation was used to address the violation of independency assumption between cycles due to multiple IVF cycles for one person and clustering nature of cycles carried out within one center. Controlling variables included age, body mass index, anti-Müllerian hormone level, cause of infertility, ovulation protocol, type of fertilisation, number of embryos transferred, number of days of Gn use. Results: Totally 102 061 cycles met eligibility criteria and were included in the analyses. In terms of effectiveness, after controlling relevant unbalanced baseline characteristics, compared with rFSH group, the high oocyte retrieval (>15 oocytes was considered high retrieval) rate of uFSH group significantly decreased in gonadotropin-releasing hormone agonist protocol (OR=0.642, P<0.01) and in gonadotropin-releasing hormone antagonist protocol (OR=0.556, P=0.001), but the clinical pregnancy rate per transfer cycle and the live birth rate per transfer cycle significantly increased (OR=1.179, OR=1.169, both P<0.01) in both agonist and antagonist protocols. For safety, multiple analysis result demonstrated that in the agonist protocol, compared with rFSH group, the incidence of moderate to severe ovarian hyperstimulation syndrome of uFSH group significantly decreased (OR=0.644, P=0.002). The differences in ectopic pregnancy rate and multiple pregnancy rate between the uFSH and rFSH groups were not significant (P=0.890, P=0.470) in all patients. In terms of cost, compared with rFSH group, the uFSH group had lower total Gn costs for each patient (P<0.01). Conclusion: For patients who underwent COS, uFSH has better safety, and economic profiles over rFSH in China.

Abstract
Objective: To study the surgical safety and efficacy of preoperative neoadjuvant therapy with immune checkpoint inhibitors combined with anti-angiogenic drugs in patients with China liver cancer staging(CNLC)-Ⅱb and Ⅲa resectable hepatocellular carcinoma. Methods: The data of 129 patients with Ⅱb and Ⅲa hepatocellular carcinoma who underwent surgery at the First Affiliated Hospital of Nanjing Medical University from January 2018 to December 2020 were analyzed. All patients were divided into two groups: the neoadjuvant therapy group(n=14,13 males and 1 female,aged (55.4±12.6)years(range:34 to 75 years)) received immune combined targeted therapy before surgery,immune checkpoint inhibitor camrelizumab was administered intravenously at a dose of 200 mg each time,every 2 weeks for 3 cycles,anti-angiogenesis drug apatinib was taken orally and continuously with a dose of 250 mg for 3 weeks and the conventional surgery group(n=115,103 males and 12 females,aged (55.8±12.0)years(range:21 to 83 years)) did not receive antitumor systemic therapy before surgery. There were 3 patients with CNLC-Ⅱb,11 with CNLC-Ⅲa in the neoadjuvant group;28 patients with CNLC-Ⅱb,87 with CNLC-Ⅲa in the conventional group. Student's t test or rank-sum test was used to compare the differences between two groups for quantitative data, Fisher's exact probability method was used to compare the differences of proportions between two groups, and Log-rank test was used to compare survival differences between two groups. Results: The 1-year recurrence rate in the neoadjuvant group was 42.9%,and the 1-year recurrence rate in the conventional group was 64.0%,with a statistically significant difference between the two groups(χ²=3.850,P=0.050);The 1-year survival rate in the neoadjuvant group was 100% and that in the conventional group was 74.2%,with a statistically significant difference between the two groups(χ²=5.170,P=0.023). According to the stratified analysis of the number of tumors,for single tumor,the 1-year recurrence rate in the neoadjuvant group was 25.0%,and that in the conventional surgery group was 71.0%,and the difference between the two groups was statistically significant(χ²=5.280, P=0.022). For multiple tumors, the 1-year recurrence rate in the neoadjuvant group was 66.7%,and the 1-year recurrence rate in the conventional surgery group was 58.9%,with no significant difference between the two groups(χ²=0.110,P=0.736). The operative time,intraoperative blood loss,and postoperative hospital stay in the neoadjuvant group were similar to those in the conventional group,and their differences were not statistically significant. Conclusions: Immune checkpoint inhibitors combined with anti-angiogenic targeted drugs as a neoadjuvant therapy for resectable hepatocellular carcinoma can reduce the 1-year recurrence rate and improve the 1-year survival rate,especially for those with solitary tumor. Limited by the sample size of the neoadjuvant group,the safety of immune combined targeted therapy before surgery cannot be observed more comprehensively,and further studies will be explored.

Abstract
Objective: To address the limitations of existing methods and tools for evaluating clinical practice guidelines, we aimed to develop a comprehensive instrument focusing on the three main dimensions of guideline development: scientificity, transparency, applicability. We will use it to rank the guidelines according to the scores. We abbreviated it as STAR, and its reliability, validity and usability were also tested. Methods: A multidisciplinary expert working group was set up, including methodologists, statisticians, journal editors, medical professionals, and others. Scoping review, Delphi methods and hierarchical analysis were used to determine the final checklist of STAR. Results: The new instrument contained 11 domains and 39 items. Intrinsic reliability of each domain was indicated by Cronbach's α coefficient, with a average value of 0.646. The Cohen's kappa coefficients for methodological evaluators and clinical evaluators were 0.783 and 0.618. The overall content validity index was 0.905. The R2 for the criterion validity analysis was 0.76. The average score for usability of the items was 4.6, and the mean time spent to evaluate each guideline was 20 minutes. Conclusion: The instrument has good reliability, validity and evaluating efficiency, and can be used for evaluating and ranking guidelines more comprehensively.

Abstract
PURPOSE Very-long-chain acyl-CoA dehydrogenase (VLCAD) is an essential mediator in fatty acid metabolism. The progression of human hepatocellular carcinoma (HCC) is closely associated with the disorder of energy supply. Here, we aimed to investigate the role and underlying molecule mechanism of VLCAD in pathological process of HCC. METHODS In this study, VLCAD was induced silencing and overexpression using small hairpin RNA (shRNA) and lentiviral-mediated vector in HCC cell lines. The proliferation of HCC cells was determined using CCK-8 assay. Transwell assay and lung metastasis were performed to analysis cell metastasis in vitro and in vivo. ECAR and OCR were used to evaluate the activity of glycolysis and mitochondrial oxidative phosphorylation. RESULTS Our data indicated that VLCAD was downregulated in human HCC tissues and cells. VLCAD overexpression strongly suppressed the proliferation and metastasis of HCC cells associating with the decrease of ATP accumulation and glycolysis activity. Importantly, the PI3K/AKT inhibitor LY294002 strongly abolished the role of shVLCAD in HCC cells. Our results suggested that VLCAD suppressed the growth and metastasis in HCC cells by inhibiting the activities of glycolysis and mitochondrial oxidative phosphorylation metabolism via PI3K/AKT pathway. CONCLUSIONS Together, present findings not only demonstrated the protective role of and molecular network of VLCAD in HCC cells but also indicated its and potential use as a target in the therapy of HCC.

Abstract
Objective: To investigate the clinical and genetic characteristics of epilepsy associated with chromosome 16p11.2 microdeletion. Methods: The patients (n=10) with 16p11.2 microdeletion found in children with epilepsy treated in Beijing Children's Hospital Affiliated to Capital Medical University from January 2018 to January 2021 were collected. The clinical manifestations, gene variations and prognosis were analyzed retrospectively. Results: A total of 10 children's data were collected, including 5 male and 5 female. The onset age of epilepsy was 4.5 (4.1,5.0) months. Regarding the seizure types, 7 cases had focal seizures with secondary generalization, 2 cases had generalized seizures, and 1 case had tonic seizures and spasms. Nine cases had cluster seizure attacks and 3 cases had status epilepticus. Seven cases had focal or multifocal epileptiform discharges in interictal electroencephalogram (EEG), 3 cases had borderline or normal EEG. Brain magnetic resonance imaging showed polymicrogyria in 1 case, paraventricular leukomalacia in 1 case, delayed myelination of white matter in 3 cases, and no obvious abnormalities in the other 5 cases. The patients were followed up for 0.5-3.5 years, with 1-3 kinds of antiepileptic drugs taken orally. The case with polymicrogyria still had seizures, however the other 9 cases had seizures controlled. The age of the last seizure attack was 8 (6, 12) months. There were 6 cases with mental and motor developmental delay before epilepsy onset. During the follow-up, 7 cases were retarded to varying degrees, while 3 cases had normal development. Regarding the genetic detection methods, 7 cases underwent whole exome sequencing, 2 cases underwent whole genome copy number variation detection, and 1 case underwent whole genome sequencing. The length of the 16p11.2 deletion in 10 cases ranged from 525 to 951 kb, and all contained the PRRT2 gene intact. Six cases were de novo variants, 1 case was inherited from the mother who had a history of convulsions in early childhood, and the source of variant was not verified in 3 cases, none of whose parents had relevant phenotype. Conclusions: The epilepsy associated with 16p11.2 microdeletion is mainly induced by the heterozygous deletion of PRRT2 gene in this region, however the phenotype is usually severe, and often combined with developmental and epileptic encephalopathy. Detection of copy number variation should be emphasized in children whose etiology is considered genetic but second-generation sequencing result is negative.

Abstract
Objective: To analyse the clinical and gene characteristics of GRIN2B gene related neurological developmental disorders in children. Methods: The data of 11 children with GRIN2B gene related neurological developmental disorders from November 2016 to February 2021 were collected from Department of Neurology, Beijing Children's Hospital, Capital Medical University, National Center for Children's Health and analyzed retrospectively. The clinical features, electroencephalogram (EEG), brain imaging and gene testing results were summarized. Results: Among 11 children 6 were boys and 5 were girls. Two of them were diagnosed with developmental and epileptic encephalopathy. The ages of seizures onset were 3 months and 9 months, respectively. Seizure types included epileptic spasm, tonic seizures, tonic spasm and focal seizures, and 1 patient also had startle attacks. EEG showed interictal multifocal epileptiform discharges. Both of them were added with more than 2 anti-seizure drugs, which were partially effective but could not control. They had moderate to severe mental and motor retardation. The phenotype of 9 cases was developmental delay or intellectual disability without epilepsy, age of visit 1 year to 6 year and 4 months of whom 5 cases had severe developmental delay, 2 cases had moderate and 2 cases had mild delay. Multi-focal epileptiform discharges were observed in 3 cases, no abnormality was found in 3 cases, and the remaining 3 cases did not undergo EEG examination. Ten cases underwent brain magnetic resonance imaging (MRI), 6 cases had nonspecific abnormalities and 4 cases were normal. Nine GRIN2B gene heterozygous variants were detected by next-generation sequencing in these 11 patients, 8 cases had missense variants and 1 case had nonsense variant, all of which were de novo and 3 of which were novel. Missense variants were found in 10 patients, among them 6 cases had severe developmental delay, 3 cases had moderate and 1 case had mild developmental delay, but the patient with nonsense variant showed mild developmental delay without epilepsy. Conclusions: The phenotypes of GRIN2B gene related neurological developmental disorders in children are diverse, ranging from mild intellectual impairment without epilepsy to severe epileptic encephalopathy. Patients with epileptic phenotype usually have an onset age of infancy, and spasm and focal seizures are the most common seizure types. And the epiletice episodes are refractory. Most of the patients with missense variants had severe developmental delay.

Abstract
Objective: To investigate the phenomenon of epileptic spasms (ES) and focal seizures (FS) in a single ictal event (FS-ES phenomenon) and to study the etiology, manifestations, and prognosis of this phenomenon. Methods: The data of the 15 neonates who had ES and FS in a single ictal event, according to video-electroencephalography (VEEG) recording in Department of Neonatology of Children's Hospital of Fudan University during the period of January 2018 to December 2019, was analyzed retrospectively. Results: Of the 15 neonates, 7 were male and 8 were female. Gestational age was 39 (32-42) weeks. Birth weight was 3 100 (1 825-3 850) g. The initial onset age of convulsions was 2 (1-10) days. The age of the first discovery of FS-ES phenomenon was 25 (14-32) days. The age of seizure-free was 7(1-27) months. All of the initial seizure types were FS. The FS-ES phenomenon of 15 patients started with FS. The FS-ES phenomenon manifested in 2 forms: FS followed by ES (12 cases), ES appeared during an FS without interrupting FS (2 cases). In 1 neonate the spasm occurred in both forms. The etiology included genetic factors (9 cases), intracranial infection (1 case), abnormal brain tissue structure (2 cases), and etiology was unknown in 3 cases. All the neonates had a poor prognosis except one. Conclusions: The FS-ES phenomenon in the neonatal period starts with FS. There are various etiologies. Etiologies of most patients are genetic factors. Most of the patients have a poor prognosis.

Abstract
Objective: To evaluate the efficacy and safety of the XEN gel implant in the treatment of glaucoma. Methods: It was a retrospective case series study. Eight patients (8 eyes) in the First Affiliated Hospital of Fujian Medical University from January 2020 to September 2020 were included, including six males and two females, aged 29 to 74 years. The patients treated with the XEN gel implanting for glaucoma. After detailed ophthalmic examination, all the patients met the surgical indications for the XEN gel implanting. Preoperative and postoperative intraocular pressure (IOP), anterior segment and fundus examination results, medication, and surgical complications were evaluated. Results: There were seven patients with primary open-angle glaucoma and one patient with glaucomatocyclitic syndrome. Five patients had received anti-glaucoma surgeries, and the remaining three patients had not received surgical treatment. All XEN gel stents were implanted successfully. All patients were followed up for 4 to 12 months. The preoperative maximum IOP ranged from 11 to 44 mmHg (median, 28 mmHg, 1 mmHg=0.133 kPa), and the IOP was 10 to 18 mmHg (median, 13 mmHg) at the last follow-up. Two to 4 types of medication were used for glaucoma preoperatively (median, 3), while 0 to 2 types (median, 0) were used at the last follow-up. During the follow-up, 7 cases were completely successful and only one case failed. Intraoperative hemorrhage occurred in two patients, and after effective treatment, the IOP decreased to below 20 mmHg. One patient was found to have an increased IOP with the XEN luminal obstruction, and the XEN drainage tube was recanalized. The IOP was about 10 mmHg at the last follow-up, and no anti-glaucoma drugs were used, but the surgery was assessed as failure by standard. The remaining patients had no other serious complications. Conclusion: This preliminary study shows that the XEN gel drainage may be a safe and effective treatment for patients with glaucoma. (Chin J Ophthalmol, 2021, 57: 679-684).

Abstract
Objective: To compare the performance of multiple machine learning algorithms in predicting recurrence after resection of early-stage hepatocellular carcinoma(HCC). Methods: Clinical data of 882 early-stage HCC patients who were admitted to the First Affiliated Hospital of Nanjing Medical University from May 2009 to December 2019 and treated with curative surgical resection were retrospectively collected. There were 701 males and 181 females,with an age of (57.3±10.5)years(range:21 to 86 years). All patients were randomly assigned in a 2∶1 ratio, the training dataset consisted of 588 patients and the test dataset consisted of 294 patients. The construction of machine learning-based prediction models included random survival forest(RSF),gradient boosting machine,elastic net regression and Cox regression model. The prediction accuracy of the model was measured by the concordance index(C-index). The prediction error of the model was measured by the integrated Brier score. Model fit was assessed by the calibration plot. The performance of machine learning models with that of rival model and HCC staging systems was compared. All models were validated in the independent test dataset. Results: Median recurrence-free survival was 61.7 months in the training dataset while median recurrence-free survival was 61.9 months in the validation dataset, there was no significant difference between two datasets in terms of recurrence-free survival(χ²=0.029,P=0.865). The RSF model consisted of 5 commonly used clinicopathological characteristics, including albumin-bilirubin grade,serum alpha fetoprotein,tumor number,type of hepatectomy and microvascular invasion. In both training and test datasets,the RSF model provided the best prediction accuracy,with respective C-index of 0.758(95%CI:0.725 to 0.791) and 0.749(95%CI:0.700 to 0.797),and the lowest prediction error,with respective integrated Brier score of 0.171 and 0.151. The prediction accuracy of RSF model for recurrence after resection of early-stage HCC was superior to that of other machine learning models,rival model(ERASL model) as well as HCC staging systems(BCLC,CNLC and TNM staging),with statistically significant difference(P<0.01). Calibration curves demonstrated good agreement between RSF model-predicted probabilities and observed outcomes.All patients could be stratified into low-risk,intermediate-risk or high-risk group based on RSF model;statistically significant differences among three risk groups were observed in both training and test datasets(P<0.01). The risk stratification of RSF model was superior to that of TNM staging. Conclusion: The proposed RSF model assembled with 5 commonly used clinicopathological characteristics in this study can predict the recurrence risk with favorable accuracy that may facilitate clinical decision-support for patients with early-stage HCC.

Abstract
OBJECTIVES To understand the sequelae of COVID-19. METHODS We followed up 1174 patients with severe coronavirus disease 2019 (COVID-19)who were recovered and discharged for 6 months. RESULTS There were 175 cases with clear IgG results 6 months after discharge, of which 82 (46.9%) were IgG (+) and 16 (9.1%) were IgG (dim+). Four hundred and forty-one participants (55.4%) had some kind of sequelae. The most common symptoms were fatigue (25.3%), sleep disorder (23.2%) and shortness of breath (20.4%). In those who had sequelae, 262 (59.4%) had more than one symptom. Critical cases were more likely to have cough (20.5% vs 11.6%, p = 0.023) and hypomnesis (15.1% vs 8.0%, p = 0.041) than severe cases. Furthermore, univariate and multivariate logistic regression analyses revealed that women are more likely to have multiple symptoms (p = 0.002), fatigue (p = 0.009) and sleep disorder (p = 0.008), whereas critical illness was found as independent risk factor for hypomnesis (p = 0.045). CONCLUSION Our study demonstrated the duration of antibody and sequelae of COVID-19 and compared the differences amongst different populations.

Abstract
The Painting Album of Cityscapes and Business was finished in the early Qing Dynasty with realism. This painting album described the prosperity in business and everyday life in Suzhou during the late Ming and the early Qing Dynasties. They were drawn and painted retrospectively, ie, the content of the pictures was based on existing paintings handed down. In the painting album, more than ten medical-related elements were specifically depicted, such as traditional Chinese medicine clinics and pharmacies and seven ophthalmology-related elements including one clinic specialized in ophthalmology, two spectacle shops, two people wearing eyeglasses and three blind people. Up to now, no specialized ophthalmology clinics and spectacle shops have been found in earlier literature and paintings. It can be speculated that the Painting Album of Cityscapes and Business is the earliest album of paintings depicting clinics specialized in ophthalmology and spectacle shops in China. This painting album provides important information for the study of the medical industry in Suzhou in the late Ming and the early Qing Dynasties, particularly, in terms of ophthalmology-related diagnosis and treatment.

Abstract
Quantitative analysis was performed on the biphasic CT of 40 patients [43-80 (66.1±9.0) years old, including 37 males] with stable chronic obstructive pulmonary disease (COPD) to measure the percentage of emphysema (Emph%); the percentage of small airway disease (SAD%) and the square root of the wall area of hypothetical airway with internal perimeter of 10 mm (Pi10). Based on the cluster analysis of Emph%, SAD% and Pi10, the patients were divided into five imaging phenotypes including no obvious imaging abnormality type (n=11), small airway disease-dominant type (n=9), bronchial wall thickening-dominant type (n=8), emphysema-dominant type (n=6) and mixed type (n=6). Patients with the same Global Initiative for Chronic Obstructive Lung Disease (GOLD) grade had similar degree of airflow limitation, but the lesion components were not identical. Being different from the traditional imaging classification, even in the cases of mild emphysema, they can be further divided into small airway disease-dominant type and bronchial wall thickening-dominant type according to the difference of airway disease.

Abstract
One of the most common birth defects is cleft palate only (CPO) of which non-syndromic cleft palate only (NSCPO) accounts for 50%. NSCPO is a complex disease where multiple genes and environmental factors contribute to its risk. Unlike non-syndromic cleft lip with or without cleft palate (NSCL/P), previous genome-wide association studies only identified a few common genetic variations achieving genome-wide significance. This review summarizes the recent findings on genetic epidemiology of NSCPO. According to the current evidence, the candidate genes are divided into three categories: candidate genes with strong evidence, candidate genes with suggestive evidence, and candidate genes with inadequate evidence. The findings of epigenetic studies, the next generation sequencing studies, interaction analysis on NSCPO are also reviewed.

Abstract
Objective: To investigate the etiology of epilepsy onset before 6 months old and improve clinical understanding. Methods: The medical history, electroencephalogram, brain imaging, genetic examination and other clinical data of 340 patients who were diagnosed with epilepsy with onset under 6 months of age and were hospitalized in the Department of Neurology, Beijing Children's Hospital, Capital Medical University between January 2017 and December 2018 were retrospectively analyzed. Rank sum test was used to compare the ages of onset of different etiologic groups. Results: Of the 340 patients, 196 were males and 144 were females. The age of onset was 90.5 (48.0, 135.5) days. In the 250 (73.5%) underwent genetic test, 103 (41.2%) had pathogenic or likely pathogenic variants, involving 43 single gene variants and 2 chromosomal abnormalities. Seventy-nine patients (23.2%) had genetic etiology, 66 (19.4%) had structural etiology, 19 (5.6%) had metabolic etiology, 13 (3.8%) had multiple etiologies, and 163 (47.9%) had unknown etiology. In the 79 cases with genetic etiology, 30 single gene variants were detected, including 19 cases of PRRT2, 10 cases of KCNQ2, 7 cases of SCN1A, 6 cases of SCN2A, 6 cases of STXBP1, 5 cases of CDKL5, 2 cases of ARX, and 1 case of each of 23 gene variants. Two cases had chromosomal abnormalities which were 21-trisomy and 16p11.2 microdeletion syndrome respectively. Among the 66 cases with structural etiologies, 37 cases had acquired factors such as perinatal brain injury, 28 cases had congenital factors such as cortical malformation and 1 case was perinatal brain injury combined megalencephaly. The onset age of genetic etiology was 95 (26, 128) days, that of structural etiology was 90 (58, 30) days, and that of metabolic etiology was 57 (30, 90) days. The onset age of metabolic etiology was earlier than that of structural etiology (U=436.500, P=0.044). Conclusions: Genetic etiology is the most common defined etiology of infants with early-onset epilepsy aged 0-6 months, and there are certain differences in the age of onset between different etiologies. Proper application of genetic test is helpful to identify the etiology and guide treatment.

Abstract
Objective: To summarize the experience of surgical treatment of primary liver cancer. Methods: The clinical data of 10 966 surgically managed cases with primary liver cancer, from January 1986 to December 2019 at Hepatobiliary Center, the First Affiliated Hospital of Nanjing Medical University, were retrospectively analyzed. The life table method was used to calculate the survival rate and postoperative recurrence rate. Log-rank test was used to compare the survival process of different groups, and the Cox regression model was used for multivariate analysis. In addition, 2 884 cases of hepatocellular carcinoma(HCC) with more detailed follow-up data from 2009 to 2019 were selected for survival analysis. Among 2 549 patients treated with hepatectomy, there were 2 107 males and 442 females, with an age of (56.6±11.1) years (range: 20 to 86 years). Among 335 patients treated with liver transplantation, there were 292 males and 43 females, with an age of (51.0±9.7) years (range: 21 to 73 years). The outcomes of hepatectomy versus liver transplantation, anatomic versus non-anatomic hepatectomy were compared, respectively. Results: Of the 10 966 patients with primary liver cancer, 10 331 patients underwent hepatectomy and 635 patients underwent liver transplantation. Patients with liver resection were categorized into three groups: 1986-1995(712 cases), 1996-2008(3 988 cases), 2009‒2019(5 631 cases). The 5-year overall survival rate was 32.9% in the first group(1986-1995). The 5-year overall survival rate of resected primary liver cancer was 51.7% in the third group(2009-2019), among which the 5-year overal survival rates of hepatocellular carcinoma, intrahepatic cholangiocarcinoma and mixed liver cancer were 57.4%, 26.6% and 50.6%, respectively. Further analysis was performed on 2 549 HCC patients with primary hepatectomy. The 1-, 3-, 5-, and 10-year overall survival rates were 88.1%, 71.9%, 60.0%, and 41.0%, respectively, and the perioperative mortality rate was 1.0%. Two hundred and forty-seven HCC patients underwent primary liver transplantation, with 1-, 3-, 5-, and 10-year overall survival rates of 84.0%, 64.8%, 61.9%, and 57.6%, respectively. Eighty-eight HCC patients underwent salvage liver transplantation, with the 1-, 3-, 5-, and 10-year overall survival rates of 86.8%, 65.2%, 52.5%, and 52.5%, respectively. There was no significant difference in survival rates between the two groups with liver transplantation (P>0.05). Comparing the overall survival rates and recurrence rates of primary hepatectomy (2 549 cases) with primary liver transplantation (247 cases), the 1-, 3-, 5-, and 10-year overall survival rates in patients within Milan criteria treated with hepatectomy and transplantation were 96.3%, 87.1%, 76.9%, 54.7%, and 95.4%, 79.4%, 77.4%, 71.7%, respectively (P=0.754). The 1-, 3-, 5-year recurrence rates were 16.3%, 35.9%, 47.6% and 8.1%, 11.7%, 13.9%, respectively(P<0.01). The 1-, 3-, 5-, 10-year overall survival rates in patients with no large vessels invasion beyond the Milan criteria treated with liver resection and transplantation were 87.2%, 65.9%, 53.0%, 33.0% and 87.6%, 71.8%, 71.8%, 69.3%, respectively(P=0.003); the 1-, 3-, 5-year recurrence rate were 39.2%, 57.8%, 69.7% and 29.7%, 36.7%, 36.7%, respectively (P<0.01). The 1-, 3-, 5-, and 10-year overall survival rates in patients with large vessels invasion treated with liver resection and transplantation were 62.1%, 36.1%, 22.2%, 15.0% and 62.9%, 31.8%,19.9%, 0, respectively (P=0.387); the 1-, 3-, 5-year recurrence rates were 61.5%, 74.7%, 80.8% and 59.7%, 82.9%, 87.2%, respectively(P=0.909). Independent prognostic factors for both overall survival and recurrence-free survival rates of HCC patients treated with liver resection included gender, neoadjuvant therapy, symptoms, AST, intraoperative or postoperative blood transfusion, tumor number, tumor size, cirrhosis, macrovascular invasion, microvascular invasion, and pathological differentiation. Propensity score matching analysis of 443 pairs further showed that there was no significant difference in overall survival rate between anatomical liver resection and non-anatomical liver resection(P=0.895), but the recurrence rate of non-anatomical liver resection was higher than that of anatomical liver resection(P=0.035). Conclusions: In the past decade, the overall survival rate of HCC undergoing surgical treatment is significantly higher than before. For HCC patients with good liver function reservation, surgical resection can be performed first, and salvage liver transplantation can be performed after recurrence. The effect of salvage liver transplantation is comparable to that of primary liver transplantation. As for the choice of liver resection approaches, non-anatomical resection can reserve more liver tissue and can be selected as long as the negative margin is guaranteed.

Abstract
Objective: To retrospectively analyze the clinical features and survival analysis of primary intestinal extranodal NK/T-cell lymphoma nasal type(ENKTL). Methods: Patients with intestinal lymphoma at the First Affiliated Hospital of Air Force Military Medical University were collected from January 2009 to December 2019, and those with primary intestinal ENKTL screened. The general situation, main symptoms, ECOG scale, lactic dehydrogenase(LDH), and β(2)-microglobulin(β(2)-MG)in the serum, lesion site and form, numbers of extranodal invasion, Lugano stage, pathological features, and lifetime and survival outcomes were evaluated. Results: In total, 34 patients with confirmed diagnosis of primary intestinal ENKTL were identified. The incidence rate of primary intestinal ENKTL is 16.2% (34/210). A total of 26 patients were men and 8 were women with the median age at diagnosis of 45 (range, 20-69)years and patients younger than 60 years account for 85.3%. It included abdominal pain (76.5%), diarrhea(20.6%), hematochezia(29.4%), and abdominal mass(2.9%), 85.3% with B-symptoms, and abnormally elevated LDH in the serum(73.5%). The lesion sites included large intestine(52.9%), small intestine(29.4%), and both of them(17.7%). The lesion forms were featured by mass(8.8%), ulcer(32.4%), diffuse infiltration(2.9%), and hybrid(55.9%). Lugano stage included stage Ⅰ/Ⅱ (70.6%)24 patients and stage Ⅳ(29.4%)10 patients. About 94.1% patients were EBER positive. The median survival time was 60 days. The overall survival rate had significant differences on ECOG scale, LDH in the serum, IPI score and complications(P=0.037, 0.009, 0.002, and 0.000, respectively). Conclusion: Primary intestinal ENKTL was commonly observed in men at young or middle age, and the most common symptom was abdominal pain, often with B-symptoms, abnormally elevated LDH in the serum. The most common site was the large intestine. The lesion forms were mainly featured by the hybrid and ulcer. It seemed that patients with IPI low-risk group and without any complication would have longer survival time.

Abstract
In recent years, osteoporosis (OP) has become one of the main diseases affecting the health of middle-aged and elderly people in China, and the prevalence of OP has increased significantly. The clinical diagnosis and treatment guidelines for this disease are also constantly updated. The overall principles speciallyemphasise that doctors and patients need to work together to negotiate the details of the diagnosis and treatment guidelines, in order to improve the OP clinical diagnosis and treatment rate. Therefore, patients' knowledge of the disease, understanding of clinical guidelines, and cooperation with doctors to implement diagnosis and treatment plans are very important. In this study, from the most concerned issues of the patients, we established the OP patient practice guideline working group. 14 recommendations, as the OP patient practice guidelines, are proposed in accordance with the relevant principles of the "World Health Organization guidelines development manual" and the international normative process.

Abstract
Objective: To summarize the clinical features of two early onset epileptic encephalopathy (EOEE) patients with arginyl-tRNA synthetase (RARS2) gene variations and to review related literature. Methods: The clinical data and genetic features of two pontocerebellar hypoplasia type 6 (PCH6) patients with RARS2 variation diagnosed by the Department of Neurology, Beijing Children's Hospital from January 2017 to December 2018 were analyzed retrospectively. A literature search with "RARS2" "pontocerebellar hypoplasia type 6" and "early onset epileptic encephalopathy" as key words was conducted at China national knowledge infrastructure (CNKI), Wanfang Data Knowledge Service Platform and PubMed (up to May 2020), literature about RARS2 gene variation patients and their complete clinical data were chosen and reviewed. Results: The onset age of the two cases (1 male, 1 female) were 2 months and 29 days respectively and the early onset symptom of them was epileptic encephalopathy. The main symptoms included seizures, development delay, microcephaly and lactic acidosis. In addition to these symptoms, the female also had dyspnea, hypoglycemia and metabolic acidosis after birth. Brain magnetic resonance imaging (MRI) of the two patients were normal at first. Follow up at four-month (case 1) and eight-month (case 2) MRI showed atrophy of cerebral and cerebellar, but the pons was not affected. All four heterozygous variations in RARS2 gene revealed by whole-exome sequencing (p.Arg560His and p.Arg6His from case 1, p.Arg254Trp and p.Phe5Ser from case 2) were novel. No eligible reports were found in Chinese journals, while 17 reports were found in English literature. Excluded cases with incomplete data together with these two cases, a total of 34 patients from 20 families were found. All patients had developmental delay while 94% (32/34) patients showed the initial symptoms within 3 months, 93% (28/30) patients were diagnosed as epilepsy, 89% (25/28) patients had progressively microcephaly and 52% (16/31) cases did not show the pons atrophy on brain MRI. Twenty of 28 cases (71%) were refractory epilepsy. There were 31 types of gene variations and most of them were missense variations (21/31, 68%). Conclusions: The majority of PCH6 cases caused by RARS2 gene variation show the initial symptoms within 3 months, characterized by EOEE, most of them are refractory epilepsy, accompanied by developmental delay, microcephaly and increased lactic acid. Brain MRI indicates progressive cerebral or pontocerebellar atrophy.

Abstract
Objective: To explore the association of urinary phenol concentration and blood biochemical indices in coke oven workers. Methods: From April to may 2019, we investigated 771 employing coke oven workers from a coke plant in Taiyuan city, and categorized into benzene-exposed group (n=402) and control group (n=369) based on their benzene exposures in workplace and urophenol concentrations. All subjects were interviewed face-to-face using a questionnaire including name, age (year) , gender, smoking and drinking habits, personal vocational history, working length (year) , and occupational protection, etc. Post-shift urine samples detected using a gas chromatography-hydrogen flame ionization detector. Fasting venous blood was drawn in the morning and centrifuged, the separated serum were detected the following items using an automatic blood biochemistry analyzer. Covariance and multiple linear regression were used to test the association of urinary phenol concentration and the levels of all the blood biochemical indices. Results: The subjects were predominantly males (n=719, 93.3%) , with an average age of (42.3±8.2) years and an average working length of (20.6±8.2) years. Compared with the control group, the benzene-exposed group were significantly different in age, working length of years, gender, smoking and drinking habits (P<0.05) . The median (interquartile interval) concentration of urinary phenol was 6.00 (0.00-33.00) μg/ml in the benzene-exposed group, which was significantly higher than that in the control group (P<0.05) . Covariance analysis indicated that the fasting blood glucose, total cholesterol and high density cholesterol in the benzene-exposed group were significantly reduced compared with the control group, yet the serum creatinine, serum uric acid and triglyceride were significantly increased (P<0.05) . Multiple linear regression showed that, an increase of each natural logarithm (Ln) transformed urinary phenol concentration was significantly associated with increases in serum uric acid level [9.82 (95%CI: 2.18-17.47) μmol/L] and cholesterol level[0.10 (95%CI:0.00-0.20) mmol/L]. An increase of each Ln-transformed accumulated benzene exposure levels was significantly associated with an increase in total cholesterol level[0.09 (95%CI: 0.01-0.17) mmol/L]. Conclusion: Occupational benzene exposure is possibly related to the variation of purine and total cholesterol metabolism in coke oven workers.
