Abstract
Objective: To explore the value of the aMAP risk score (age, male, albumin-bilirubin, and platelets) to predict early recurrence within one year after microwave ablation in patients with small hepatocellular carcinoma. Methods: This was a retrospective study that enrolled 142 patients diagnosed with hepatocellular carcinoma who were treated with microwave ablation in the Department of Hepatology Unit of Nanfang Hospital, Southern Medical University from July 2016 to July 2021. The cohort enrolled 121 male and 21 female patients, including 110 patients that were <60 years old. All the patients were followed-up after microwave ablation to evaluate residual tumor and recurrence of tumor by computed tomography or magnetic resonance imaging. The observation indices mainly included general data and imaging data of patients. Using the X-tile tools, patients were divided into two groups: a high aMAP score group and a low aMAP score group. Multivariate Cox regression analysis was conducted for comparison of independent risk factors. Results: Multivariate Cox regression showed that high aMAP score, maximum tumor diameter >20 mm, and high AFP were the independent risk factors of early recurrence (all P<0.05). Kaplan-Meier survival curves showed that the median recurrence-free survival was 25.5 months in the low aMAP score group and 6.1 months in the high aMAP score group (P=0.001). Conclusions: The aMAP score could predict the early recurrence within 1 year of small hepatocellular carcinoma after microwave ablation. Patients with high aMAP score should undergo rigorous postoperative follow-up evaluations..

Abstract
Primary liver cancer is the second leading cause of death from malignant tumors in China, and hepatocellular carcinoma (HCC) is the main type. The disease stage at the time of HCC diagnosis largely determines the efficacy of subsequent treatment. Due to the HCC screening among high-risk population has not yet popularized, and the current diagnose method of early HCC is not satisfactory, the early HCC diagnosis rate is less than 30% in China. Metabolomics research emerging in recent years has promoted the research progress of HCC in many fields, such as elaborating the mechanism of occurrence and development, early prevention and diagnosis, exploring drug treatment targets. At the same time, a large number of serum metabolites with excellent sensitivity and specificity were discovered, which made up for the deficiency of traditional serological indicators and helped the early screening and early diagnosis of HCC. This review will summarize the studies on serum metabolomic markers of HCC in recent 5 years, explore the role of metabolomics in the early prediction and diagnosis of HCC and its application prospect.

Abstract
In 2016, the World Health Organization set an ambitious goal of reducing viral hepatitis-related deaths by 65% by 2030. The key to this goal is to reduce viral hepatitis-related HCC deaths. Liver cancer is the fourth most common malignant tumor and the second leading cause of cancer death in China. The onset of HCC is insidious, and most patients are already in the middle and late stage when diagnosed. Despite the great progress on management of HCC, the therapeutic effect and prognosis of HCC are still unsatisfactory. Therefore, multi-dimensional and comprehensive analysis of the mechanism of liver cancer, improving the early screening, diagnosis and treatment rate of liver cancer are the key points of reducing the harm of liver cancer in China. In recent years, multi-omics studies have been widely applied in the field of liver cancer, providing a basis for the pathogenesis of liver cancer, early detection and diagnosis, development of individual treatment strategies and prognosis assessment. This issue will focus on the application of genomics, proteomics, metabolomics and imaging omics in early screening, diagnosis and treatment of liver cancer.

Abstract
Objective: To evaluate the roles between two different HIV self-testing models in promoting HIV-testing among men who have sex with men (MSM). Methods: This paper focuses on two HIV self-testing service models. The first; is the online self-testing model (HIV self-testing conventional model) with the sexual health promotion network platform. The other one is an innovative HIV self-testing model (secondary distribution model), based on the previous program. The two different self-testing models, including the number of indexes and alters, the positive rate, and the demographics of indexes and alters, are compared. The influence of volunteers with or without leadership on the number of HIV self-test kits distributed or self-use is analyzed through the leadership survey scale. Results: The return rates of HIV self-testing results in the two models are 94.7%(323/341) and 99.2%(1 141/1 150), respectively, within 30 days. The proportion of alters in the secondary distribution is significantly higher (45.9%,281/612) than the conventional HIV self-testing (6.3%,20/318). In the secondary distribution model, the difference between the number of indexes and alters indicators including age, marital status, residence, sex orientation, anal sex with men in the past six months, and HIV test are statistically significant (χ2 test, all P<0.05). The opinion leader of MSM has significantly impacted the promotion of HIV self-testing (P<0.05). Conclusions: Both models can promote HIV self-testing, result return, and HIV positive detection among MSM. In terms of expanding the testing and detection of HIV positive, the secondary distribution mode shows more obvious advantages, which significantly promotes a large number of MSM who have never been tested for HIV to undergo HIV testing. Influential indexes have a significant effect on increasing the HIV testing rate and promoting HIV testing among MSM.

Abstract
Objective: To analyze the cost-effectiveness and willingness-to-pay of HIV self-testing (HIVST) strategy and facility-based HIV rapid testing (HIV-RDT) strategy in men who have sex with men (MSM) in Zhuhai, and provide scientific evidence for making health policy. Methods: From the perspective of health service providers, the data of the costs and effectiveness of two HIV testing strategies in MSM in Zhuhai during January-September 2019 were collected, and a decision-tree model of cohort of 10 000 MSM was constructed by using software TreeAge Pro 2019 to measure the cost-effectiveness ratio (CER) and the incremental cost-effectiveness ratio (ICER). One-way and probability sensitivity analysis was performed for the uncertainty of the parameters in the model, and the cost-effectiveness and affordability curve was introduced to estimate the affordability of two strategies. Results: After the mobilization of MSM community-based organization through Internet and social media, 2 303 MSM had HIVST, in whom 33 were HIV positive (1.7%), and 816 MSM received HIV-RDT, in whom 35 were HIV positive (4.3%). The cost for per screening was 60.45 yuan and 240.43 yuan (RMB) respectively, and the cost for per positive screening was 4 218 yuan and 5 606 yuan (RMB) rerspectively. The results of the decision-tree model showed that the mean cost for a MSM using HIVST and using HIV-RDT was 44.67 yuan and 148.42 yuan (RMB) respectively, and the ICER was negative. HIVST strategy was a more cost-effective option when the willing-to-pay was below 6 528 yuan (RMB) for per positive screening, and HIV-RDT strategy was a more cost-effective option when the investment was higher than 6 528 yuan (RMB). Conclusion: HIVST strategy in Zhuhai is a public health project with economic value, and policy makers should strengthen the support to MSM community-based organization to promote the application of HIVST among MSM.

Abstract
BACKGROUND LTCBDE combined with or without modified techniques is safe and efficacious for the management of gallstones and concomitant, even large, common bile duct (CBD) stones. METHODS To describe the surgical indications and procedure strategies of laparoscopic transcystic common bile duct exploration (LTCBDE), a retrospective analysis of 205 patients with concomitant gallstones and CBD stones treated using LTCBDE between June 2008 and June 2015 was performed. Clinical data on disease characteristics, methods for cystic duct incision and CBD stone extraction (with or without laser lithotripsy), and surgical outcomes were collected and reviewed. RESULTS CBD stones were successfully cleared in all patients. No patient was converted to choledochotomy or laparotomy. The cystic duct diameter ranged 3-8 mm, and 85 patients with cystic duct diameter ≥ 5 mm. The mean time for CBD stone extraction was 25.3 min, with the operative time ranged from 63 to 170 min. Lithotripsy was used in 74 (36.1%) patients among which 26 patients with cystic duct diameter ≥ 5 mm. Estimated blood loss during surgery was 10-120 ml per patient, and no intra-operative blood transfusions were needed. The mean postoperative hospital stay was 5.1 (range 3-7) days, and postoperative complications developed in seven patients. No bile duct injury, stricture, remnant, recurrent stones, or other adverse events were observed during the mean follow-up of 8 months. CONCLUSIONS Based on preoperative MRCP and intra-operative IOC findings about cystic duct diameter, the diameter of CBD, CBD stone size, we summarized and proposed the surgical indications and suitable techniques and strategies during LTCBDE.

Abstract
Our study aimed to determine if a double-dose pre-S containing hepatitis B virus (HBV) vaccination (Sci-B-Vac) could elicit an adequate and sustainable immune response in HBV patients who developed spontaneous hepatitis B surface antibody (anti-HBs) response after liver transplant. PATIENTS AND METHODS All patients who received transplants for HBV-related disease for >1 year with normal graft function and hepatitis B surface antigen seronegativity were evaluated. They received a 40-μg HBV vaccine if they were responders in our previous vaccine trial, if anti-HBs was positive for >1 year after liver transplant (LT), or if a peak anti-HBs at any time point after LT was >100 mIU/mL. Primary endpoint was the development of anti-HBs ≥ 10 mIU/mL from previous negative value or a 1-log increase from baseline. RESULTS A total of 86 patients were recruited; 5 were responders from a previous trial; 45 patients had detectable anti-HBs >1 year after LT, and 36 patients had an anti-HBs >100 mIU/mL. All (5/5, 100%) previous responders responded to booster vaccination. For the remaining 81 patients, 10 of 81 (12.3%) responded. CONCLUSION All previous responders responded to booster vaccination, implying durability and memory of HBV immune response, which is an important prerequisite for definitive host immunity for HBV. In patients who had spontaneous anti-HBs production after LT, a single vaccination can induce response in 12.3% of patients.

Abstract
Objective: To assess the characteristics of facial nerve canal between normal anatomy and dysplasia of children in different ages. Methods: A total of 492 health ears were divided into six groups, neonatal group (<1 m , n=42), infancy group(1 m-1 y, n=106), toddler group(1-3 y, n=102), preschool group (3-6 y, n=100), school group(6-10 y, n=60)and adolescent group (10-14 y, n=82). The length and diameter of facial nerve canal and that angles of first and second genu were measured with CT in each group. Results: ①The lengths of facial nerve canal in neonatal and infancy group were shorter than other four groups, especially in the mastoid segments of facial nerve canal. The lengths of mastoid segments in neonatal, infancy, toddler, preschool, school and adolescent groups were 5.03±0.84, 6.25±1.40, 8.34±1.38, 9.70±1.34, 10.84±1.41 and 12.17±1.83 mm, with P<0.05, respectively. After school age, the lengths of labyrinthine and tympanic segment grew slowly or developed completely (P>0.05). ② The diameter of labyrinth and tympanic segment in neonatal group were narrower than other five groups (P<0.05), but no significant difference among them in other groups (P>0.05). ③The dysplasia of facial nerve canal were occurred on 978 locations. Among them, the percentage of dehiscence, aberrance, partially expanding and bifurcation were 72.9%(713/978), 5.1%(50/978), 18.9%(185/978) and 3.1%(30/978) respectively. The percentage of dehiscence in geniculate fossa segment was decreased significantly with age (neonatal group 85.7%(36/42), infancy group 59.4%(63/106), toddler group 39.2%(40/102), preschool group 33%(33/100), school group 30%(18/60)and adolescent group 26.8%(22/82), with P<0.05). Except the dehiscence of geniculate fossa and mastoid segment, there was no significant difference in the occurrence rate of the other variants (P>O.05). Conclusions: The growth of length and dehiscence in labyrinth segment of facial nerve canal are significant in difference ages. The changes of diameter and angles of first and second genu in facial nerve canal, and the rate of other dysplasia are individual.

Abstract
A 1:1 matched case-control study of etiologic fraction (EF) of female lung cancer was conducted in Guangdong Province. 200 female cases with primary lung cancer were selected and 200 female controls matched by age, area of residence and education from five hospitals. Multiple conditional logistic regression analysis turned out that passive smoking from spouse, bad ventilation in kitchen, liking for pickles or salted fish, history to chronic bronchitis, family history of tumour, pulmonary tuberculosis, taking oral contraceptive were the independent risk factors of female lung cancer (OR = 2.16-40.55, P < 0.05). EF of the independent risk factors were 0.535, 0.432, 0.252, 0.124, 0.115, 0.072, 0.069 respectively. The interactions between passive smoking from spouse and risk factors which included taking oral contraceptive, family history of tumour, bad ventilation in kitchen, history of pulmonary tuberculosis, liking for pickles or salted fish were analyzed. The result revealed that EF (AxB) (aetiologic fraction attributable to interaction) were 0.848, 0.499, 0.479, 0.416, 0.346 respectively. The interaction index were 0.906, 0.543, 0.578, 0.427, 0.441. These findings indicate passive smoking from spouse, particularly those had a history of taking oral contraceptive, increases the risk of female lung cancer.
