Abstract
Wastewater-based epidemiology (WBE) is an emerging discipline, which has been applied to drug abuse tracking and infectious disease pathogen surveillance. During the COVID-19 epidemic, WBE has been applied to monitor the epidemic trend and SARS-CoV-2 variants etc. In order to detect hidden COVID-19 cases and prevent transmission in the community, wastewater surveillance system for monitoring SARS-CoV-2 RNA was developed in Shenzhen. The sewage sampling sites were set up in key places such as the port areas, urban villages and residential communities of Futian, Nanshan, Luohu and Yantian districts. From July 26 to November 30, 2022, a total of 369 sewage sampling sites were set up, covering 1.93 million people. Continuous sampling was carried out for 3 hours in the peak period of water use every day. Sewage virus enrichment and SARS-CoV-2 nucleic acid detection were carried out by polyethylene glycol precipitation method and RT-qPCR, and a positive water sample disposal process was molded. This article aims to introduce the case of source tracing of COVID-19 infected patients based on urban sewage in Shenzhen. The sewage monitoring of Honghu water treatment plant in Luohu District played an early warning role, and the source of infection was traced. In the disposal of positive water samples in Futian South Road, Futian District, the important experience of monitoring point layout was obtained. In the sewage monitoring of Nanshan village, Nanshan District, the existence of occult infection was revealed. Sharing the experience of tracing the source of COVID-19 patients to avoid the spread of COVID-19 in the community based on wastewater surveillance of SARS-CoV-2 RNA in Shenzhen, and summarizing the advantages and application prospects of sewage surveillance can provide new ideas for monitoring emerging or re-emerging pathogens that are known to exhibit gastrointestinal excretion in the future.

Abstract
Objective: To explore the epidemiological characteristic of a COVID-19 outbreak caused by 2019-nCoV Omicron variant BF.7 and other provinces imported in Shenzhen and analyze transmission chains and characteristics. Methods: Field epidemiological survey was conducted to identify the transmission chain, analyze the generation relationship among the cases. The 2019-nCoV nucleic acid positive samples were used for gene sequencing. Results: From 8 to 23 October, 2022, a total of 196 cases of COVID-19 were reported in Shenzhen, all the cases had epidemiological links. In the cases, 100 were men and 96 were women, with a median of age, M (Q1, Q3) was 33(25, 46) years. The outbreak was caused by traverlers initial cases infected with 2019-nCoV who returned to Shenzhen after traveling outside of Guangdong Province.There were four transmission chains, including the transmission in place of residence and neighbourhood, affecting 8 persons, transmission in social activity in the evening on 7 October, affecting 65 persons, transmission in work place on 8 October, affecting 48 persons, and transmission in a building near the work place, affecting 74 persons. The median of the incubation period of the infection, M (Q1, Q3) was 1.44 (1.11, 2.17) days. The incubation period of indoor exposure less than that of the outdoor exposure, M (Q1, Q3) was 1.38 (1.06, 1.84) and 1.95 (1.22, 2.99) days, respcetively (Wald χ2=10.27, P=0.001). With the increase of case generation, the number and probability of gene mutation increased. In the same transmission chain, the proportion of having 1-3 mutation sites was high in the cases in the first generation. Conclusions: The transmission chains were clear in this epidemic. The incubation period of Omicron variant BF.7 infection was shorter, the transmission speed was faster, and the gene mutation rate was higher. It is necessary to conduct prompt response and strict disease control when epidemic occurs.

Abstract
Current osteoporosis medications have drawbacks of causing side effects and having slow onset, therefore developing osteoporosis drugs with faster onset and less side effects is essential. This study investigated the effects of the natural plant extract, SDTL-E, in ovariectomized (OVX)-induced osteoporosis rats. Rats were randomly assigned to sham operation control group (Control Group); OVX rat model group (Model Group) or OVX rat SDTL-E treatment group (SDTL-E Group). All groups underwent ovariectomy, but the Control Group did not have the ovaries removed. SDTL-E Group was treated with SDTL-E, Model and Control Groups were treated with vegetable oil, treatments were topically applied twice daily for 20 days. Results showed when compared with Model Group, SDTL-E Group significantly restored serum estradiol back to near Control Group level, serum ALP activity, serum and urinary calcium were significantly decreased, bone mechanics indicators increased and trabecular bone numbers slightly increased. These results demonstrated 20 days of SDTL-E topical treatment improved bone strength and trabecular bone structure in OVX-induced osteoporosis rats. The underlying mechanisms include restoring estradiol level, reducing bone turnover, net bone resorption, bone calcium loss, and calcium excretion through kidney. These findings suggest topical application of plant extract is a potential new approach with quick efficacy for treating osteoporosis.

Abstract
Objective: To explore the effects of circTNPO1 on the proliferation and metastasis of osteosarcoma (OS) by sponging miR-338-3p. Methods: The expression of circTNPO1 on osteoblasts and multiple OS cell lines were detected by qRT-PCR. CircTNPO1 stable knockdown 143B cell line was constructed by sh-circTNPO1. Cell count kit 8 (CCK-8) assay and wound healing assay were applied to evaluate the proliferation and metastasis of this cell. Luciferase reporter assay was used to explore the binding between circTNPO1 and miR-338-3p. In xenograft tumor model, miR-338-3p inhibitor or its control was injected into the circTNPO1 knockdown tumors. The weight and size of the tumors were evaluated and Ki-67 expression was detected by immunohistochemistry. Results: The RNA expression of circTNPO1 in OS cell lines U2OS, HOS, MG63, 143B, ZOS and ZOSM were 2.73±0.27, 3.18±0.54, 4.33±0.52, 5.75±0.65, 4.50±0.49 and 3.96±0.35, respectively, higher than 1.00±0.09 in hFOB1.19 (P<0.001). CCK-8 assay revealed that after 48 h and 72 h, the absorbance of sh-circTNPO1 #1 was 0.81±0.05 and 1.09±0.06, while sh-circTNPO1 #2 143B cells was 0.84±0.04 and 1.2±0.04, which were sharply reduced compared with the control (1.00±0.06 and 1.49±0.06, P<0.001); after 48 h and 72 h, the absorbance of 143B cells transfected with circTNPO1 #1 and miR-338-3p (0.92±0.06 and 1.32±0.07) were higher than those of cells transfected with sh-circTNPO1 cells and miR NC (0.92±0.06 and 1.32±0.07, P<0.050). Wound healing assay demonstrated that the 24 hour-migration rates of sh-circTNPO1 #1 and sh-circTNPO1 #2 cells were (24.43±2.15)% and (39.70±4.20)% respectively, which were significantly lower than that of the control [(56.51±3.27)%, P<0.010]; the migration rates of sh-circTNPO1 #1+ miR NC and sh-circTNPO1 #1+ miR-338-3p inhibitor were (26.70±2.21)% and (46.10±5.71)%, with a significant difference (P<0.005). In xenograft tumor model, the weight and size of tumors in control, sh-circTNPO1 #1+ miR NC and sh-circTNPO1 #1+ miR-338-3p inhibitor mice were (458.80±158.10) mg, (262.50±82.09) mg, (395.40±137.60) mg and (593.00±228.40) mm(2,) (203.30±144.20) mm(2,) (488.60±208.60) mm(2,) respectively. Compared with control, sh-circTNPO1 tumors were significantly smaller (P<0.01). Injection with miR-338-3p inhibitor significantly reversed both the weight and size of tumors (P<0.05). Conclusion: CircTNPO1 promotes the proliferation and metastasis of OS by sponging miR-338-3p, which could be a new target for OS treatments.

Abstract
Objective: To explore the effect of neoadjuvant immunotherapy on pulmonary function and the efficacy in patients with resectable non-small cell lung cancer. Methods: Data of 30 patients with non-small cell lung cancer (NSCLC) who received neoadjuvant immunotherapy before surgery in the Chest Hospital of Shanghai Jiaotong University from March 2018 to September 2021 were retrospectively collect. The efficacy and safety of neoadjuvant immunotherapy in the perioperative period and changes in pulmonary function of patients before and after neoadjuvant treatment were valuated. Results: The patients were all-male with age of (61±8)years old, The major pathological response (MPR) rate of patients receiving neoadjuvant immunotherapy was 43%(13 cases), the pathologic complete response (pCR) rate was 37% (11 cases), disease control rate (DCR) was 97% (29 cases), objective response rate (ORR) was 67% (20 cases). The forced expiratory volume in one second (FEV1) after treatment was (2.59±0.63) L, and the ratio of FEV1 to the predicted value (FEV1%pred) was 85.27%±15.86%, which were significantly higher than those before treatment [(2.48±0.59)L, 81.73%±15.94%, respectively] (P=0.013, 0.022, respectively). Forced vital capacity (FVC) after treatment was (3.59±0.77) L, which was also significantly higher than before [(3.47±0.76) L,P=0.036]; while there were no statistical difference in FEV1/FVC and FVC accounted for the proportion of predicted values (FVC%pred) between before and after treatment (P=0.084, 0.344, respectively). The ratio of carbon monoxide dispersion (DLCO) to the predicted value (DLCO%pred) decreased from 83.61%±13.10% to 78.69%±13.85% after treatment (P=0.023). There was no significant difference in the incidence of postoperative complications between the DLCO%pred decreased group and the non-decreased group (3/18 vs 0/6; P=0.546). Conclusions: Neoadjuvant immunotherapy can increase the rate of MPR and PCR, significantly increase FEV1 and FEV1%pred, but also lead to a decrease in DLCO%pred; neoadjuvant immunotherapy does not increase the incidence of postoperative complications.

Abstract
Objective: To investigate the influencing factors of pneumoconiosis complicated with tuberculosis in order to provide the scientific evidence for formulating the preventive strategies. Methods: From July 2019 to January 2020, all occupational pneumoconiosis patients reported in Guangzhou from 1958 to 2018 were investigated retrospectively (n=1155) . The basic data (including gender, diagnosis time, diagnosis age, dust exposure duration, period, pneumoconiosis disease type, work type and industry) were obtained from pneumoconiosis case card and network report database. The data of pulmonary tuberculosis were collected from the occupational disease diagnosis files of Guangzhou Occupational Disease Prevention and Control Hospital, and were supplemented by telephone follow-up. The distribution of pneumoconiosis and tuberculosis in Guangzhou was analyzed. Binary logistic regression analysis model was used to analyze the influencing factors of pneumoconiosis complicated with pulmonary tuberculosis. Results: Among the 1155 new cases of pneumoconiosis, 357 cases were pneumoconiosis tuberculosis, and the complication rate of tuberculosis was 30.9%. Year of diagnosis, age of diagnosis, dust exposure duration, pneumoconiosis caused by mineral dust and construction industry were influencing factors for pneumoconiosis complicated with pulmonary tuberculosis (OR=0.948, 1.048, 0.972, 3.112, 2.815, P<0.05) . After the adjustment of gender, diagnosis year, diagnosis age, dust exposure duration and diagnosis period, the risk of pulmonary tuberculosis in rock drilling workers was 1.462 times higher than that in other types of work (P<0.05) . Conclusion: The complication rate of tuberculosis in patients with pneumoconiosis is relatively high. The main influencing factors are the year of diagnosis, age of diagnosis, dust exposure duration, the type of pneumoconiosis and the industry. The importance of occupational health examination and health education on prevention and treatment of tuberculosis should be emphasized among dust-exposed workers and pneumoconiosis patients. People with susceptibility factors are the top priority.

Abstract
BACKGROUND Accumulating evidence have shown that the intestinal microbiota plays an important role in prevention of host obesity and metabolism disorders. Recent studies also demonstrate that early life is the key time for the colonization of intestinal microbes in host. However, there are few studies focusing on possible association between intestinal microbiota in the early life and metabolism in adulthood. Therefore the present study was conducted to examine whether the short term antibiotic and/or probiotic exposure in early life could affect intestinal microbes and their possible long term effects on host metabolism. RESULTS A high-fat diet resulted in glucose and lipid metabolism disorders with higher levels of visceral fat rate, insulin-resistance indices, and leptin. Exposure to ceftriaxone in early life aggravated the negative influences of a high-fat diet on mouse physiology. Orally fed TMC3115 protected mice, especially those who had received treatment throughout the whole study, from damage due to a high-fat diet, such as increases in levels of fasting blood glucose and serum levels of insulin, leptin, and IR indices. Exposure to ceftriaxone during the first 2 weeks of life was linked to dysbiosis of the fecal microbiota with a significant decrease in the species richness and diversity. However, the influence of orally fed ceftriaxone on the fecal microbiota was limited to 12 weeks after the termination of treatment. Of note, at week 12 there were still some differences in the composition of intestinal microbiota between mice provided with high fat diet and antibiotic exposure and those only fed a high fat diet. CONCLUSIONS These results indicated that exposure to antibiotics, such as ceftriaxone, in early life may aggravate the negative influences of a high-fat diet on the physiology of the host animal. These results also suggest that the crosstalk between the host and their intestinal microbiota in early life may be more important than that in adulthood, even though the same intestinal microbes are present in adulthood.

Abstract
MicroRNA168 (miR168) is a key miRNA that targets Argonaute1 (AGO1), a major component of the RNA-induced silencing complex1,2. Previously, we reported that miR168 expression was responsive to infection by Magnaporthe oryzae, the causal agent of rice blast disease3. However, how miR168 regulates immunity to rice blast and whether it affects rice development remains unclear. Here, we report our discovery that the suppression of miR168 by a target mimic (MIM168) not only improves grain yield and shortens flowering time in rice but also enhances immunity to M. oryzae. These results were validated through repeated tests in rice fields in the absence and presence of rice blast pressure. We found that the miR168-AGO1 module regulates miR535 to improve yield by increasing panicle number, miR164 to reduce flowering time, and miR1320 and miR164 to enhance immunity. Our discovery demonstrates that changes in a single miRNA enhance the expression of multiple agronomically important traits.

Abstract
Alzheimer's disease (AD) is characterized by memory dysfunction, Aβ plaques together with phosphorylated tau-associated neurofibrillary tangles. Unfortunately, the present existing drugs for AD only offer mild symptomatic cure and have more side effects. As such, developments of effective, nontoxic drugs are immediately required for AD therapy. Present study demonstrates a novel role of Chinese medicine prescription Yuan-Hu Zhi Tong (YZT) in treating AD, and it has substantiated the in vivo effectiveness of YZT in two different transgenic mice models of AD, namely P301S tau and 3XTg-AD mice. Oral treatment of YZT significantly ameliorates motor dysfunction as well as promotes the clearance of aggregated tau in P301S tau mice. YZT improves the cognitive function and reduces the insoluble tau aggregates in 3XTg-AD mice model. Furthermore, YZT decreases the insoluble AT8 positive neuron load in both P301S tau and 3XTg-AD mice. Using microarray and the "Connectivity Map" analysis, we determined the YZT-induced changes in expression of signaling molecules and revealed the potential mechanism of action of YZT. YZT might regulate ubiquitin proteasomal system for the degradation of tau aggregates. The research results show that YZT is a potential drug candidate for the therapy of tau pathogenesis and memory decline in AD.

Abstract
Objective: To evaluate the clinical characteristics and prognosis of gallbladder cancer (GBC) patients in China. Methods: This retrospective multicenter cohort study enrolled 3 528 consecutive GBC patients diagnosed between January 2010 to December 2017 in 15 hospitals from 10 provinces. There were 1 345 (38.12%) males and 2 183 (61.88%) females.The age of diagnosis was (63.7±10.8) years old (range: 26 to 99 years old) .There were 213 patients (6.04%) in stage 0 to Ⅰ, whereas 1 059 (30.02%) in stage Ⅱ to Ⅲ, 1 874 (53.12%) in stage Ⅳ, and 382 (10.83%) unavailable. Surgery was performed on 2 255 patients (63.92%) . Three hundred and thirty-six patients received chemotherapy or radiotherapy (9.52%; of which 172 were palliative); 1 101 (31.21%) received only supportive treatment.The patient source, treatment and surgery, pathology, concomitant gallstone, and prognosis were analyzed. Results: Among the 3 528 GBC patients, 959 (27.18%) were from East China, 603 (17.09%) from East-North China, 1 533 (43.45%) from Central China, and 433(12.27%) from West China. Among the 1 578 resectable tumor, 665 (42.14%) underwent radical surgery, 913 (57.86%) underwent surgery that failed to follow the guidelines.Eight hundred and ninety-one (56.46%) patients were diagnosed before surgery, 254 (16.10%) during surgery, and 381 (24.14%) after surgery (time point of diagnosis couldn't be determined in 52 patients) .Among the 1 578 patients with resectable tumor, 759 (48.10%) had concomitant gallstone.Among the 665 patients underwent radical surgery, 69 (10.4%) showed positive resection margin, 510 (76.7%) showed negative resection margin, and 86 (12.9%) unreported margin status.The 5-year overall survival rate (5yOS) for the 3 528-patient cohort was 23.0%.The 5yOS for patients with resectable tumor was 39.6%, for patients with stage ⅣB tumor without surgery was 5.4%, and for patients with stage ⅣB tumor underwent palliative surgery was 4.7%. Conclusions: More than half GBC patients in China are diagnosed in stage Ⅳ.Curative intent surgery is valuable in improving prognosis of resectable GBC.The treatment of GBC needs further standardization.Effective comprehensive treatment for GBC is in urgent need.

Abstract
Objective: To compare the efficacy between thymectomy plus prednisone and prednisone alone in patients with non-thymoma myasthenia gravis (MG). Methods: Thirty generalized MG patients without thymoma who underwent thymectomy were collected as the operation group, and thirty-nine patients without thymectomy who were treated with prednisone alone were matched as the control group. The start point was the enrollment time and the endpoint event was the "clinical remission" (including complete stabilization remission, drug remission, and poor performance). The survival curve was used to analyze the difference of endpoint event time between the two groups. Besides, a 12-month follow-up study was conducted to compare relevant clinical indicators between the two groups. Results: There was no significant difference in the occurrence time of endpoint events between the two groups (P=0.614). After 6-month follow-up, no significant differences were found in clinical remission rate, the dosage of pyridostigmine bromide and prednisone, the peak dosage of prednisone, the use of other immunosuppressive medications and the rate of hospitalization for exacerbation of disease between the two groups (all P>0.05). After 12-month follow-up, the dosage of prednisone and pyridostigmine in the operation group was significantly lower than that in the control group (5(0,10)mg/d vs 7.5(5,10)mg/d and 30(0,105)mg/d vs 90(15,180)mg/d; P=0.038, 0.032). Conclusion: In patients with mild to moderate non-thymoma generalized MG, thymectomy does not achieve faster remission, but it does reduce the long-term dosage of prednisone and bromopyrazine.

Abstract
Gastric cardia adenocarcinoma (GCA) is one of the most common types of cancer and the incidence is increasing globally. MicroRNAs (miRNAs) have been reported to play critical roles in the progression of GCA. However, the exact role of miR-638 in GCA and its underlying mechanism remain largely unknown. The expression levels of miR-638 and metastasis-associated in colon cancer 1 (MACC1) were measured by quantitative real-time polymerase chain reaction (qRT-PCR). Cell proliferation, apoptosis, migration and invasion were detected by Cell Counting Kit-8 (CCK-8) assay, flow cytometry and transwell assay, respectively. Western blot analysis was performed to determine the protein levels of cleaved-caspase 3 (C-caspase 3) and MACC1. The possible binding sites of miR-638 and MACC1 were predicted by TargetScan online software and confirmed by dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay. A xenograft model was established to investigate the roles of MACC1 in GCA in vivo. The expression of miR-638 was evidently reduced and MACC1 expression was obviously enhanced in GCA tissues and cells. Overexpression of miR-638 or knockdown of MACC1 inhibited cell proliferation, migration and invasion but increased apoptosis in GCA cells. Moreover, MACC1 was a direct target of miR-638 and its upregulation attenuated the inhibitory effect of miR-638 overexpression on the progression of GCA. In addition, overexpression of miR-638 significantly decreased tumor growth by downregulating MACCI in vivo. In conclusion, miR-638 overexpression suppressed cell proliferation, migration and invasion but induced cell apoptosis by targeting MACC1 in GCA cells, providing a potential therapeutic strategy for the treatment of GCA.

Abstract
Objective: To evaluate the clinical characteristics of myelin oligodendrocyte glycoprotein antibody (MOG-IgG) associated myelitis in a cohort of Chinese Han adults. Methods: From January 2016 to December 2017, 70 patients with MOG-IgG associated disorders (MOGAD) and 120 patients with aquaporin 4 antibody (AQP4-IgG) positive neuromyelitis optica spectrum disorders (NMOSD) visited the NMO/MS clinic or the neurology ward of Huashan Hospital, and the neurophthalmology clinic of Eye and ENT hospital, Shanghai Medical College, Fudan University were enrolled. The clinical and paraclinical data of the patients were retrospectively reviewed. The characteristics of MOG-IgG associated myelitis were further clarified. Results: Sixteen of the 70 patients with MOGAD had ever experienced myelitis. The frequency of myelitis was 18.6% at the first attack and 22.9% throughout the disease duration. The onset age of MOG-IgG associated myelitis was 9-57(30±11) years, and the female to male ratio was 0.6∶1. Compared with AQP4-IgG positive myelitis attacks, MOG-IgG associated myelitis attacks were more common to be accompanied by feverish prodromal symptom (30.8%) while less common to exhibit painful tonic (12.5%). Longitudinally extensive myelitis (>3 vertebral segments) was less frequent (56.3%), and short-segment myelitis and multiple short-segment myelitis could also be seen. MRI showed that MOGAD patients had more lower spinal cord lesions (20%), fewer cervical cord lesions (40%) and less transverse lesions (52%). Axial H sign was a distinct feature (36%). MOG-IgG associated myelitis attack also demonstrated a lower EDSS score after treatment. Conclusion: MOG-IgG associated myelitis should be recognized as an important clinical component of MOGAD.

Abstract
The present paper analyzes the typical unified lattice Boltzmann (LB) models for different convection-diffusion (CD) problems in multiphase systems. The CD problems in multiphase systems can be roughly classified into three groups: CD problems with a continuous scalar value and a continuous flux, a discontinuous scalar value and a continuous flux, a continuous scalar value and a discontinuous flux. The characteristics of the corresponding unified LB models for the three kinds of CD problems are analyzed and the equivalence between the LB models based on different perspectives or numerical schemes is revealed. Finally, a comprehensive multiphase LB model (CMLBM) capable of solving different isotropic and anisotropic CD problems in multiphase systems is proposed. Four typical CD problems in multiphase systems are calculated to validate the CMLBM; the results show that it performs well against the typical isotropic and anisotropic CD problems in multiphase systems.

Abstract
Background Pancreatic adenocarcinoma is often diagnosed at an advanced stage when adjacent vascular invasion is present. Accurate evaluation of presence of vascular invasion can help guide therapy. The aim of this study was to construct a nomogram for preoperative prediction of peripancreatic vein invasion in patients with pancreatic head cancer. Study design Data of patients with carcinoma head of pancreas and suspected peripancreatic invasion (n = 247) who underwent pancreatic resection with venous reconstruction between January 2012 and January 2017 at four academic institutions were retrospectively analyzed. Univariate and multivariate analyses were used to identify independent risk factors for vein invasion from among demographic, biological, conditional host-related, and anatomical data. A predictive nomogram was constructed based on the identified independent risk factors. Results The nomogram was constructed using data from 181 patients while the validation cohort consisted of 66 patients. Length of tumor contact (P = 0.031), circumferential vein involvement (P = 0.048), and venous contour abnormalities (P = 0.001) were independent predictors of venous invasion. The C-index of the model in predicting venous invasion was 0.963 for the external validation cohort. Patients could be assigned into low- (< 50%), intermediate- (50–90%), and high-risk (> 90%) groups based on the nomogram to facilitate personalized management. Conclusions Vein invasion by pancreatic head cancer is mainly associated with anatomical factors. The nomogram for prediction of vein invasion was found to be practicable.

Abstract
BACKGROUND Pancreatic head adenocarcinoma is commonly diagnosed at an advanced stage when adjacent vascular invasion is present. This study aimed to establish a preoperative prognostic nomogram for patients who underwent attempted curative resectional surgery for pancreatic head cancer with suspected peripancreatic venous invasion. METHODS Data on all consecutive patients were retrospectively collected from 2012 to 2016 at four academic institutions. The demographic and radiological parameters were analyzed using univariate and multivariate Cox regression analyses. The final nomogram was established using the concordance Harrell's C-indices and calibration curves from data obtained in three institutions and validated in the cohort of patients coming from the fourth institution. RESULTS The nomogram was constructed using data from 178 patients while the validation cohort consisted of 61 patients. Age, length of tumor contact, peripancreatic venous abnormalities and lymph node staging were independent factors of overall survival. The nomogram showed good probabilities of survival on calibration curves. The C-index of the model in predicting overall survival (OS) was 0.824 for the validation cohort. CONCLUSIONS The nomogram accurately predicted OS in patients with pancreatic head cancer with suspected peripancreatic venous invasion after attempted curative pancreatic resectional surgery.

Abstract
OBJECTIVE To compare the clinical treatment efficiency of platelet-rich fibrin (PRF) assisted revascularization and traditional revascularization in immature permanent teeth. METHODS Eighteen non-vital immature permanent teeth of sixteen patients which were diagnosed as necrotic pulpitis with (or without) periapical inflammations were treated with PRF assisted revascularization. Twenty-two teeth non-vital immature permanent teeth of twenty patients which were diagnosed as necrotic pulpitis with (or without) periapical inflammations were treated with traditional revascularization. All the cases were accorded with inclusive criteria and were treated at Pediatric Dentistry of Peking University School and Hospital of Stomatology. The cases were followed up clinically and radiographically at regular intervals. Clinical examinations and periapical radiographs were recorded and analyzed. Clinical success rate was evaluated based on the clinical and radiographic findings. The changes of root length, dentine wall thickness and apical foramen width of the teeth from the two groups were measured and compared according to the preoperative and by recalling the periapical radiographs. RESULTS The cases were followed up for 6-16 months. Clinically, totally 17 out of the 18 teeth in PRF group and 21 out of the 22 teeth in traditional group were asymptomatic with no sensitivity to percussion or palpation. PRF group tended to be more effective than traditional group clinically without significant differences (P=0.446). Radiographically, 15 out of the 18 teeth in PRF group and 15 out of the 22 teeth in traditional group displayed that the roots developed, showing that root length and dentine wall thickness increased and apical foramen closed. There was a marked difference in dentine wall thickening in PRF group in comparison with traditional group (P=0.039). However, the changes of root length increasing (P=0.411) and apical foramen width closure (P=0.737) were comparable in both groups. The result in electric pulp test (P=0.517), root canal calcification (P=0.324) and crown discolor (P=0.386) were also comparable in the two groups. CONCLUSION PRF assisted revascularization and traditional revascularization in non-vital immature permanent teeth which were diagnosed as necrotic pulpitis with (or without) periapical inflammations resulted in similar clinical outcomes. Both methods showed good prognosis. PRF revascularization seemed to have better effect on dentine wall thickening than traditional method.

Abstract
Objective: To evaluate the patients' survival and effectiveness of the live cancer screening for population at high risk for liver cancer in Qidong. Methods: According to the Expert Scheme proposed the Expert Committee of Early Detection and Early Treatment, China Cancer Foundation, diagnostical screening by using combined methods of alpha-fetoprotein and B ultrasound monitoring were carried out biannually in individuals with positive HBsAg who were screened from Qidong area. The evaluation indices of the effectiveness are task completion rate of screening, detection rate of liver cancer, early diagnosis rate, and treatment rate. The deadline of the follow-up for the surviving outcome was March 31, 2016. The life-table method was used to calculate the observed survival, and to make comparison and significant tests between survival rates in Group A (those found via repeated periodic screening) and Group B (those diagnosed without periodic screening). Results: Since 2007, 38 016 target population have been screened, and 3 703(9.74%) individuals with positive HBsAg were found. Except for 29 patients with liver cancer at the initial screening, 3 674 persons in the cohort were followed up; 268 patients with liver cancer were detected from the 33 199 person-times screening, with an annual detection rate of 1.61%. Of them, 186 patients were found in Group A(1.12%), in which 149 patients were the early cases, with an early detection rate of 80.11%; 167 out of 186(89.78%) patients received treatment after diagnosis. The incidence of liver cancer in this HBsAg (+ ) cohort of 25 452 person-years was 1 052.96 per 100 000 annually, 187 cases in males(1 488.45/100 000)and 81 cases in females(628.46/100 000). The 1-, 3-, 5-, and 8-year survival of all patients with liver cancer were 64.55%, 40.50%, 32.54%, and 19.65%, respectively. The 1-, 3-, 5-, and 8-year survival rates were 77.16%, 49.04%, 38.53%, and 24.25% in Group A, and were 36.25%, 21.21%, 21.21%, and 0% in Group B, respectively, with significant differences between two groups (P<0.05). Conclusion: The findings show that screening of individuals at high-risk of development of liver cancer, with semiannual AFP and B ultrasound, according to the Expert Scheme, is effective not only in increasing detection rate but also in detecting liver cancer at early stage, and in improving patients' survival as well.

Abstract
Objective: To observe the clinical efficacy and factors associated with outcome of extracorporeal membrane oxygenation (ECMO) in refractory cardiogenic shock patients. Methods: Patients with refractory cardiogenic shock received ECMO treatment in our hospital from May 2013 to November 2015 were retrospectively analyzed. The clinical status before ECMO support, ECMO timing, complications and outcome were observed and analyzed.The hemodynamic data and the amount of vasoactive drugs at 2 hours before ECMO support and at 2, 6, 24 and 48 hours after ECMO support were collected and compared. Results: Ten refractory cardiogenic shock patients were included in this study (5 acute fulminant myocarditis patients, 4 acute myocardial infarction patients, 1 myocardial rupture patient (6 males, 4 females, age ranged 12 to 56 years). Before ECMO, the mean left ventricular ejection fraction (LVEF) was (31.4±10.2)%, the mean score of APACHE Ⅱ was 26.6±10.8. Eight patients developed cardiac arrests and the duration of CPR ranged from 10 to 300 minutes and three patients received IABP. CVP decreased, BP increased, HR decreased, ScVO2 increased, dose of dobutamine decreased at 2 hours after ECMO support. After ECMO support for 6 hours, lactate decreased, dose of norepinephrine decreased. After ECMO support for 24 and 48 hours, hemodynamics became stable and shock was significantly improved. Complication including infection of limb and catheterization site occurred in 3 patients, femoral arterial thrombosis occurred in 2 patients, critical limb ischemia occurred in 2 patients, hemorrhage at the catheterization site occurred in 2 patients. The duration of ECMO ranged from 2 to 220 hours. Nine patients could be weaned off ECMO support and 6 patients survived to hospital discharge. Two patients died due to too late ECMO support, the other two patients died due to severe complication of limb. Conclusions: ECMO can rapidly improve hemodynamic stability of patients with cardiogenic shock. Accurate assessing the timing of ECMO support and decreasing complication of limb play a critical role on improving outcome in refractory cardiogenic shock patients.

Abstract
Krüppel-like factor 8 (KLF8) is highly expressed in hepatocellular carcinoma (HCC) and contributes to tumor initiation and progression by promoting HCC cell proliferation and invasion. However, the role of KLF8 in liver cancer stem cells (LCSCs) is not known. In the current study, we investigated the role of KLF8 in LCSCs to determine if KLF8 is a novel marker of these cells. We found that KLF8 was highly expressed in primary HCC tumors, distant migrated tissues, and LCSCs. Patients with high KLF8 expression had a poor prognosis. KLF8 promoted stem cell-like features through activation of the Wnt/β-catenin signaling pathway. Cell apoptosis was significantly increased in HCC cells with knockdown of KLF8 compared with the control cells when treated with the same doses of sorafenib or cisplatin. Taken together, our study shows that KLF8 plays a potent oncogenic role in HCC tumorigenesis by maintaining stem cell-like features through activation of the Wnt/β-catenin signaling pathway and promoting chemoresistance. Thus, targeting KLF8 may provide an effective therapeutic approach to suppress tumorigenicity of HCC. © 2016 Wiley Periodicals, Inc.

Abstract
BACKGROUND & AIMS Whether perioperative blood transfusions (PBTs) negatively impact oncologic outcomes after curative resection for HCC remains controversial. We aimed to identify the independent predictive factors of PBT for curative resection of hepatocellular carcinoma (HCC), and to investigate the impact of PBT on long-term recurrence and survivals after resection. METHODS Of 1103 patients who underwent curative liver resection for HCC between 1999 and 2010, 285 (25.8%) patients received PBT. Univariable and multivariable regression analyses were used to identify independent predictive factors of PBT. Propensity scores and Cox regression analyses were used to compare the overall survival (OS) and recurrence-free survival (RFS) between patients who did and did not receive PBT. RESULTS Multivariable regression analysis revealed that performance status, preoperative hemoglobin, cirrhosis, portal hypertension, tumor rupture, tumor size, macroscopic vascular invasion, and intraoperative blood loss were independent predictive factors of PBT for HCC resection. Propensity score matching analysis created 234 pairs of patients. Before propensity matching, PBT was significantly associated with increased risks of OS (HR: 2.455, 95% CI: 2.077-2.901, p<0.001) and RFS (HR: 2.018, 95% CI: 1.718-2.370, p<0.001) in the entire cohort. After propensity matching, PBT was not significantly associated with increased risks of OS (HR: 1.229, 95% CI: 0.988-1.527, p=0.063) and RFS (HR: 1.188, 95% CI: 0.960-1.469, p=0.113). After adjustment for other prognostic variables in the propensity matched cohort, PBT was still found not to be associated with OS and RFS after HCC resection. CONCLUSIONS The present study identified that PBT did not influence RFS and OS after curative resection of HCC.

Abstract
OBJECTIVE STK33 has been reported to play an important role in cancer cell proliferation. We investigated the role of STK33 in hepatocellular carcinoma (HCC) and its underlying mechanisms. DESIGN 251 patients with HCC were analysed for association between STK33 expression and clinical stage and survival rate. Tamoxifen (TAM)-inducible, hepatocyte-specific STK33 transgenic and knockout mice models were used to study the role of STK33 in liver tumorigenesis. HCC cell lines were used to study the role of STK33 in cell proliferation in vitro and in vivo. RESULTS STK33 expression was found to be frequently upregulated in patients with HCC. Significant associations were found between increased expression of STK33 and advanced HCC staging and shorter disease-free survival of patients. Overexpression of STK33 increased HCC cell proliferation both in vitro and in vivo, whereas suppression of STK33 inhibited this effect. Using a TAM-inducible, hepatocyte-specific STK33 transgenic mouse model, we found that overexpression of STK33 resulted in increased hepatocyte proliferation, leading to tumour cell burst. Using a TAM-inducible, hepatocyte-specific STK33 knockout mouse model, we found that, when subjected to the diethylnitrosamine (DEN) liver cancer bioassay, STK33KO(flox/flox, Alb-ERT2-Cre) mice exhibited a markedly lower incidence of tumour formation compared with control mice. The underlying mechanism may be that STK33 binds directly to c-Myc and increases its transcriptional activity. In particular, the C-terminus of STK33 blocks STK33/c-Myc association, downregulates HCC cell proliferation, and reduces DEN-induced liver tumour cell number and tumour size. CONCLUSIONS STK33 plays an essential role in hepatocellular proliferation and liver tumorigenesis. The C-terminus of STK33 could be a potential therapeutic target in the treatment of patients with STK33-overexpressed HCC.

Abstract
Hepatocellular carcinoma (HCC) is the sixth most common cancer and the third most common cause of cancer-related deaths worldwide. The Barcelona Clinic Liver Cancer (BCLC) classification has been endorsed as the optimal staging system and treatment algorithm for HCC by the European Association for the Study of Liver Disease and the American Association for the Study of Liver Disease. However, in real life, the majority of patients who are not considered ideal candidates based on the BCLC guideline still were performed hepatic resection nowadays, which means many hepatic surgeons all around the world do not follow the BCLC guidelines. The accuracy and application of the BCLC classification has constantly been challenged by many clinicians. From the surgeons’ perspectives, we herein put forward some comments on the BCLC classification concerning subjectivity of the assessment criteria, comprehensiveness of the staging definition and accuracy of the therapeutic recommendations. We hope to further discuss with peers and colleagues with the aim to make the BCLC classification more applicable to clinical practice in the future.

Abstract
OBJECTIVE The aim of this study was to investigate the prognostic value of tumor size alone on long-term survival and recurrence after curative resection for solitary hepatocellular carcinoma (HCC) without macroscopic vascular invasion. METHODS A single-center cohort of 615 patients with solitary HCC (a single tumor, without macroscopic vascular invasion or distant metastasis) undergoing curative hepatic resection from 2002 to 2010 was retrospectively studied. Using 2.0, 3.0, 4.0, 5.0, 8.0, and 10.0 cm as cut-off values of tumor size, the overall survival (OS) and recurrence-free survival (RFS) rates were compared between the groups of patients with tumor size up to a certain cut-off value and the groups of patients with tumor size above that cut-off value. Thus, multiple comparisons were done. The prognostic factors of OS and RFS were evaluated using univariate and multivariate analyses. RESULTS The median tumor size of all HCCs was 4.0 cm (range 0.9-22.0 cm). The in-hospital mortality rate was 1.0 %, and the overall morbidity rate was 22.3 %. The 1-, 3-, and 5-year OS rates were 96.0, 79.8, and 69.9 %, and the corresponding RFS rates were 83.6, 72.7, and 57.2 %, respectively. On univariate analyses, the 1-, 3-, and 5-year OS and RFS rates were significantly different between the individual two groups of patients as divided by the aforementioned different cut-off values of tumor sizes (all p < 0.05). However, when tumor size was put as a continuous variable into multivariate analysis, it was no longer an independent prognostic factor of OS or RFS after curative resection. CONCLUSIONS Tumor size did not independently affect long-term survival and recurrence after curative resection of solitary HCC without macroscopic vascular invasion. Therefore, there is no size limit that precludes hepatic resection for solitary HCC, provided the tumor is resectable.

Abstract
To investigate the appropriate cutoff point of CA19-9 for prognosis and other potential prognostic factors that may affect survival of patients with hilar cholangiocarcinoma (HC) after radical surgery. 168 patients who had undergone radical surgery for hilar cholangiocarcinoma and resultant macroscopic curative resection (R0 and R1) were discreetly selected for analyses. Categorized versions were used in univariate model to determine the appropriate cutoff point of CA19-9. CA19-9 and other clinicopathologic factors were analyzed for influence on survival by univariate and multivariate methods. The strongest univariate predictor among the categorized preoperative CA19-9 measures was CA19-9 less than 150 IU/L (P = 0.000). In univariate analysis, tumor size, Bismuth-Corlette classification, portal vein invasion, Lymph node metastasis, resection margin and preoperative CA19-9 levels were identified as significant prognostic factors. In multivariable analysis, lymph node metastasis, resection margin and preoperative CA19-9 levels were independent prognostic factors. our results demonstrated that preoperative CA19-9 levels was also an independent prognostic factor for hilar cholangiocarcinoma, and the most discriminative cutoff point of CA19-9 for prognosis proved to be at 150 U/ml.

Abstract
INTRODUCTION Hepatocellular carcinoma (HCC) occurring in pregnancy is quite rare. The prognosis is usually poor because of a delay in diagnosis. Reported cases of HCC in pregnancy are largely isolated with no large experience. Thus the effect of pregnancy on the prognosis of patients with HCC and the risk factors of developing HCC in pregnancy are not well documented. Our aim was to review our experience with management of four young pregnant women with HCC. PRESENTATION OF CASE Laboratory tests were performed before surgery. We analyzed the effects of age, hepatitis B surface antigens status, cirrhosis at presentation, gestational age of fetus, and maternal outcome. DISCUSSION Increase in alpha-fetoprotein (AFP) level was somewhat useful for diagnosis. Three patients died in 5 months, 6 months, and 24 months from HCC recurrence, and another patient is alive without disease 12 months postoperatively. CONCLUSION Surgery for HCC during pregnancy should be similar to that for non-pregnant women. Complete excision of tumor without termination of pregnancy provides the greatest chance of survival for women with HCC during pregnancy but depends on gestational age of the fetus. Adjuvant treatments are required to improve the long-term results of this type of surgery. The 28-week gestational week is a critical point of fetal maturation which is very important in deciding whether pregnancy should be terminated or not. The pregnancy was terminated in two of our patients when spontaneous rupture of HCC was diagnosed to save the mother's life.

Abstract
The present study focuses on the neuroprotective effect of glycyrrhizic acid (GA, a major compound separated from Glycyrrhiza Radix, which is a crude Chinese traditional drug) against glutamate-induced cytotoxicity in differentiated PC12 (DPC12) cells. The results showed that GA treatment improved cell viability and ameliorated abnormal glutamate-induced alterations in mitochondria in DPC12 cells. GA reversed glutamate-suppressed B-cell lymphoma 2 levels, inhibited glutamate-enhanced expressions of Bax and cleaved caspase 3, and reduced cytochrome C (Cyto C) release. Exposure to glutamate strongly inhibited phosphorylation of AKT (protein kinase B) and extracellular signal-regulated kinases (ERKs); however, GA pretreatment enhanced activation of ERKs but not AKT. The presence of PD98059 (a mitogen-activated protein/extracellular signal-regulated kinase kinase [MEK] inhibitor) but not LY294002 (a phosphoinositide 3-kinase [PI3K] inhibitor) diminished the potency of GA for improving viability of glutamate-exposed DPC12 cells. These results indicated that ERKs and mitochondria-related pathways are essential for the neuroprotective effect of GA against glutamate-induced toxicity in DPC12 cells. The present study provides experimental evidence supporting GA as a potential therapeutic agent for use in the treatment of neurodegenerative diseases.

Abstract
Amyloid deposits consist of protein fibrils and amorphous material, and this deposition is related to oxidative stress. Previously, we demonstrated the presence of high-density lipoproteins and/or lipids in amyloid deposits of familial amyloid polyneuropathy patients. In this study, the presence of myeloperoxidase (MPO) in amyloid deposits was demonstrated using immunohistochemical staining. In contrast, normal surrounding tissues were consistently negative for MPO. Nitrotyrosine was present in amyloid deposits after being exposed to the MPO/H2O2/NO(-) system by immunohistochemical staining, and the oxide mediated modification of serum transthyretin (TTR) was observed upon exposure to the MPO/H2O2 system using two-dimensional gel electrophoresis and TTR Western blotting. This observation revealed that the TTR amyloid deposits and serum TTR were oxidized by the MPO/H2O2/NO(-) system. Nitric oxide-mediated modification of TTR may play a role in amyloidogenesis in vivo.

Abstract
Pancreaticobiliary maljunction (PBM) is a type of congenital anomaly present in pancreatic duct development. Surgery is a reliable treatment for acute pancreatitis and biliary calculi induced by PBM, and can reduce the risk of carcinoma from congenital biliary dilatation. However, there have been few reports on postoperative complications. Here we report a case of recurrent gallstones in residual bile ducts after surgery for PBM. A review of the literature was also performed.

Abstract
A study of 7,388 consecutive patients after hepatic resection between 2011 and 2012 identified hepatolithiasis, cirrhosis, and intraoperative blood transfusion as the only independent risk factors of both incisional and organ/space surgical site infection (SSI). Patients with these conditions should be cared for with caution to lower SSI rates.

BACKGROUND Improvements in surgical technique and perioperative care have made partial hepatectomy a safe and effective treatment for hepatocellular carcinoma (HCC), even in the event of spontaneous HCC rupture. METHODS A consecutive cohort of patients who underwent partial hepatectomy for HCC between 2000 and 2009 was divided into a ruptured group and a non-ruptured group. Patients with ruptured HCC were further divided into emergency and staged hepatectomy subgroups. Mortality and morbidity, overall survival and recurrence-free survival (RFS) were compared. Prognostic factors for overall survival and RFS were identified by univariable and multivariable analyses. RESULTS A total of 1233 patients underwent partial hepatectomy for HCC, of whom 143 had a ruptured tumour. The morbidity and mortality rates were similar in the ruptured and non-ruptured groups, as well as in the emergency and staged subgroups. In univariable analyses, overall survival and RFS were lower in the ruptured group than in the non-ruptured group (both P < 0·001), and also in the emergency subgroup compared with the staged subgroup (P = 0·016 and P = 0·025 respectively). In multivariable analysis, spontaneous rupture independently predicted poor overall survival after hepatectomy (hazard ratio 1·54, 95 per cent confidence interval 1·24 to 1·93) and RFS (HR 1·75, 1·39 to 2·22). Overall survival and RFS after hepatectomy for ruptured HCC in the emergency and staged subgroups were not significantly different in multivariable analyses. CONCLUSION Spontaneous rupture predicted poor long-term survival after hepatectomy for HCC, but surgical treatment seems possible, safe and appropriate in selected patients.

Abstract
Conjunctival inclusion cysts are the most common cystic lesions of the conjunctiva and are either congenital or acquired; the latter are more prevalent. Some of the major factors that provoke the development of an acquired cyst are surgery, trauma, and chronic inflammation. Here, we report on a conjunctival inclusion cyst that developed following a case of untreated chronic conjunctivitis. To temporarily relieve the patient's symptoms a needle aspiration of the cyst was performed, and the patient was referred to an ophthalmologist for surgical excision of the cyst.

Abstract
PURPOSE The BCLC staging classification has been widely endorsed to predict the prognosis of patients with HCC. However, its validity as a means of therapeutic instructions needs to be challenged. This study aimed to evaluate perioperative and long-term outcomes of surgical resection in patients with advanced hepatocellular carcinoma (HCC) according to the Barcelona Clinic Liver Cancer (BCLC) staging. METHODS This study used a prospectively maintained database consisting of a consecutive series of 511 Chinese patients with advanced HCC who underwent surgical resection in a hepatobiliary surgical center from 2001 to 2007. Mortality, morbidity, long-term overall survival (OS) and disease-free survival (DFS) were evaluated. RESULTS Hospital mortality was 2.3%, and overall morbidity was 31.3%. After a median follow-up period of 27.8 months (range, 0-112 months), the 1-, 3- and 5-year OS rate was 69.9, 41.2 and 30.5%, and the 1-, 3- and 5-year DFS rate was 48.2, 30.3 and 24.0%, respectively. The 1-, 3- and 5-year OS and DFS rates were significantly poorer in patients with vascular invasion and/or extrahepatic spread than those in patients without (both P < 0.001), and also poorer in patients with biliary invasion than those in patients without (both P < 0.05). CONCLUSIONS Surgical resection could be considered in part of patients with advanced HCC (BCLC stage C), with low mortality, acceptable morbidity and favorable survival benefits. These results imply that BCLC recommendations for treatment schedules of advanced HCC need to be re-evaluated.

Abstract
Krüppel-like factor 8 (KLF8) plays important role in cell cycle and oncogenic transformation. Here we report the mechanisms by which KLF8 crosstalks with Wnt/β-catenin signaling pathway and regulates hepatocellular carcinoma (HCC) cells proliferation. We show that overexpression of KLF8 and nucleus accumulation of β-catenin in the human HCC samples are positively correlated. More importantly, KLF8 protein levels plus nucleus accumulation of β-catenin levels were significantly elevated in high-grade HCC compared to low-grade HCC. Using HCC HepG2 cells we find that, on the one hand both protein and mRNA of KLF8 are up-regulated under Wnt3a stimulation, on the other hand overexpression of KLF8 increases the cytoplasm and nucleus accumulation of β-catenin, recruits p300 to β-catenin/T-cell factor 4 (TCF4) transcription complex, enhances TOP flash report gene transcription, and induces Wnt/β-catenin signaling target genes c-Myc, cyclin D1 and Axin1 expression. Knockdown of KLF8 using shRNA inhibits Wnt3a induced transcription of TOP flash report gene and expression of c-Myc, cyclin D1 and Axin1. Knockdown of β-catenin by shRNA rescues the enhanced HepG2 and Hep3B cells proliferation ability induced by overexpression of KLF8.

Abstract
Arsenic is highly toxic to living cells, especially skin, and skin cancer is induced by drinking water containing arsenic. The molecular mechanisms of arsenic-induced cancer, however, are not well understood. To examine the initial processes in the development of arsenic-induced cancer, we analyzed calcium signaling at an early stage of arsenic treatment of human primary cells and compared the effects with those observed with arsenic treatment in carcinoma-derived cells. We found that arsenic inhibited inositol trisphosphate receptor (IP3R) function in the endoplasmic reticulum by inducing phosphorylation, which led to decreased intracellular calcium levels. Blockade of IP3R phosphorylation by the serine/threonine protein kinase Akt inhibitor wortmannin rescued calcium signaling. In contrast, arsenic treatment of cells derived from a carcinoma (human squamous carcinoma; HSC-1) for 1h had no obvious effect. Taken together, these results suggest that arsenic-induced reduction in calcium signaling is one of the initial mechanisms underlying the malignant transformation in the development of skin cancer.

Abstract
AIM: To investigate the clinical features and prognostic factors of advanced hepatocellular carcinoma (HCC) patients presenting with lung metastasis at initial diagnosis.
METHODS: Between 2001 and 2010, we recruited 76 consecutive HCC patients initially presenting with lung metastasis, without co-existing metastasis from other sites. These patients were divided into three groups: untreated group (n = 22), single treatment group (n = 19), and combined treatment group (n = 35).
RESULTS: Metastasis of bilateral lung lobes was common and noted in 35 patients (46.1%), and most of patients (59/76, 77.6%) presented with multiple lung metastatic nodules. Nineteen patients (25.0%) received single-method treatment, including hepatectomy in 4, transcatheter arterial chemoembolization in 6, radiotherapy in 5, and oral sorafenib in 4. Thirty-five patients (46.1%) received combined treatment modalities. The overall median survival of the all patients was 8.7 ± 0.6 mo; 4.1 ± 0.3, 6.3 ± 2.5 and 18.6 ± 3.9 mo, respectively in the untreated group, single treatment group and combined treatment group, respectively, with a significant difference (log-rank test, P < 0.001). Multivariate analysis revealed that Child-Pugh score, the absence or presence of portal vein tumor thrombus, and treatment modality were three independent prognostic factors affecting survival of patients with advanced HCC and concomitant lung metastasis.
CONCLUSION: Combined treatment modalities tend to result in a better survival as compared with the conservative treatment or single treatment modality for HCC patients initially presenting with lung metastasis.

Abstract
Background & Aims: The aim of this prospective cohort study was to investigate the impact of preoperative hepatitis B viral load, as well as postoperative antiviral therapy, on the risk of long-term survival after curative resection of hepatitis B virus-related hepatocellular carcinoma (HCC). Methods A prospective cohort of hepatitis B virus-related HCC patients undergoing curative resection from 2001 to 2007 was studied. According to preoperative viral load (using 10,000 copies/mL of hepatitis B virus DNA level as cut-off value), two groups were compared. Prognostic factors for overall survival and recurrence-free survival were evaluated. Additionally, subgroup analysis was conducted in patients with high viral load to investigate prediction of postoperative antiviral therapy on the long-term prognosis. Results With a median follow-up of 49.1 months, patients with high viral load had lower median overall survival (78.3 months vs. 111.4 months, P < 0.001) and RFS (44.6 months vs. 94.8 months, P < 0.001) compared with those with low viral load. Multivariate analysis revealed that preoperative high viral load was an independent risk factor affecting both overall survival and recurrence-free survival (both P < 0.001). The subgroup analysis revealed that postoperative antiviral therapy independently improved recurrence-free survival for patients with high viral load (P = 0.001). Conclusions Hepatitis B virus-related HCC patients with preoperative high viral load led to poorer overall and recurrence-free survival than those with low viral load after curative resection. To prevent postoperative recurrence, antiviral therapy should be initiated in those patients with hepatitis B virus DNA ≤ 10,000 copies/ml.

Abstract
AIM Minimally invasive video-assisted thyroidectomy (MIVAT) and endoscopic thyroidectomy through areola (ETA) access are among the endoscopic approaches for thyroidectomy that have been perfected, but reports comparing the two are lacking. This study evaluated the safety, postoperative recovery, and patient satisfaction of MIVAT compared with ETA. METHODS This study included 119 patients undergoing MIVAT and 42 patients undergoing ETA from January 2006 to October 2009. Operative time, complications, postoperative recovery, cosmetic result, and patient satisfaction were analyzed. RESULTS The ETA group had a higher percentage of women (100% vs. 78.2%, P<0.05) and was younger (33.5 vs. 39 years, P<0.05). Thyroid volume (24.5 vs. 14.5 mL, P<0.001) and nodular diameter (26 vs. 22 mm, P<0.05) were larger in ETA group. The MIVAT group had a shorter operative time (28.2 vs. 112.8 minutes) and a lower rate of intraoperative (7.2 vs. 21.2 mL) and postoperative (0 vs. 80 mL, P<0.0001) blood loss. Rates of conversion and complications were similar. Postoperative pain at 12 hours was 1.9 in MIVAT vs. 3.1 in ETA (P<0.0001). Hospitalization was 1 day in the MIVAT group vs. 3.5 days in ETA (P<0.0001). Patient satisfaction was similar. CONCLUSION MIVAT and ETA showed similar results for safety, although ETA might be considered more invasive than MIVAT. Patients of both groups were equally satisfied with the cosmetic result. Differently from ETA, MIVAT allows total thyroidectomy to be performed also for malignant diseases. Although different, the two approaches were safe and reliable and both are valid options. Choice might depend on the surgeon's preference, thyroid size, type of disease, and the patient's expectation about cosmesis.

Abstract
BACKGROUND Major hepatic resection of more than three segments in patients with hepatocellular carcinoma (HCC) is a high-risk operation, especially in patients with co-existing underlying liver diseases. The present study evaluated risk factors for postoperative morbidity and mortality after major hepatic resection in HCC patients with underlying liver diseases. METHODS Perioperative data of 305 HCC patients with underlying liver diseases who underwent major hepatic resection were evaluated by univariate and multivariate analyses to identify risk factors for postoperative morbidity and mortality. RESULTS The overall morbidity rate was 37.0% (n = 113), caused by pleural effusion (n = 56), ascites (n = 43), subphrenic effusion/infection (n = 23), hepatic dysfunction (n = 22), bile leakage (n = 10), respiratory infection (n = 7), incision infection (n = 7), intra-abdominal hemorrhage (n = 5), and others. The hospital mortality rate was 2.6% (n = 8), primarily caused by liver failure (4/8). Multivariate logistic regression analysis showed that preoperative platelet count <100 × 10(9)/l (P = 0.006), and increased intraoperative blood loss (≥ 800 ml) (P = 0.008) were independent risk factors of postoperative morbidity, and that preoperative prothrombin time >14 s (P = 0.015) and preoperative platelet count <100 × 10(9)/l (P = 0.007) were independent risk factors for significant hospital mortality. CONCLUSIONS Careful preoperative selection of patients in terms of the Child-Pugh classification and decrease of intraoperative blood loss are important measures to reduce postoperative morbidity after major hepatic resection in HCC patients with underlying liver diseases. Moreover, we should be aware that preoperative platelet count is independently associated with postoperative morbidity and mortality for those patients following major hepatic resection.

Abstract
The Qidong cancer registry was established in 1972, and registration of cases is done by active and passive methods. The registry contributed data on 33 cancer sites or types registered during 1992-2000 for this survival study. Data on 22 cancers registered during 1972-2000 were utilized to elicit the survival trend by period and cohort approaches. Follow-up was done by a mixture of active and passive methods, with median follow-up ranging from 2-25 months. The proportion of cases with histologically verified cancer diagnosis ranged from 9-100%, and 87-100% of total registered cases were included for survival analysis. The top-ranking cancers on 5-year age-standardized relative survival (%) were thyroid (78%), breast (58%), corpus uteri (54%), larynx (51%) and urinary bladder (42%). The corresponding survival rates for common cancers were liver (6%), lung (7%) and stomach (18%). The 5-year relative survival by age group fluctuated and showed no distinct pattern or trend. The comparison of 5-year relative survival trend by cohort and period approaches revealed that period survival closely predicted the survival experience of cancer cases diagnosed in that period for most cancers.

Abstract
PURPOSE Surgical resection remains the gold standard for hepatocellular carcinoma (HCC). Although various staging systems have been developed in recent years, the best tool for staging of HCC remains controversial. The aims of this study were to establish a new staging for patients with HCC undergoing surgical resection and to identify whether this staging is superior to other staging systems in predicting survival of resectable HCC. METHODS The subjects of this retrospective study were 958 consecutive HCC patients who underwent surgical resection between 2000 and 2006. Predictors of survival were identified using the Kaplan-Meier method and the Cox model. The disease state was staged by our proposed Eastern staging system by integrating independent risk predictors, as well as six existing staging systems. The accuracy of prediction of 1-, 3-, and 5-year mortality for each system was evaluated by the area under the receiver operating characteristic curve (AUC). RESULTS Macroscopic vascular invasion, multiple tumors, performance status 1-2, microscopic vascular invasion, extrahepatic spread, tumor size > 5 cm, albumin < 35 g/L, aspartate aminotransferase > 40 U/L, total bilirubin > 17 μmol/L, and presence of cirrhosis were identified as independent risk factors of survival after resection by multivariate analysis. The comparison of the results of the different staging systems showed that our Eastern staging had the best homogeneity (likelihood ratio χ(2) test 543.51, P < 0.001), monotonicity of gradients (linear trend χ(2) test 414.97, P < 0.001), and discriminatory ability (the highest AUCs for 1-, 3-, and 5-year mortality). CONCLUSIONS Compared with other existing staging systems, our proposed Eastern staging system shows a superior predictive ability in a Chinese cohort of patients with resectable HCC, and it can give important prognostic information after surgery.

Abstract
OBJECTIVE This study aimed to evaluate the perioperative and long-term results of partial hepatectomy for patients with complicated bilateral primary hepatolithiasis. SUMMARY BACKGROUND DATA Hepatolithiasis is best managed by a multidisciplinary approach. Definitive treatment can be offered using endoscopic, percutaneous, laparoscopic, or open surgical approaches. Partial hepatectomy is only indicated for recurrent, troublesome, localized, and severe disease affecting the liver. METHODS From January 2000 to December 2006, 136 consecutive patients who underwent bilateral (n = 54) or unilateral (n = 82) hepatectomy for biliary strictures and bilateral primary hepatolithiasis in our center were included in this study. All patients had concomitant bile duct exploration. Their perioperative and long-term outcomes were analyzed. RESULTS The immediate stone clearance rates after bilateral and unilateral hepatectomy were 81.5% and 65.9%, respectively. Additional postoperative choledochoscopic lithotripsy raised the clearance rates to 85.2% and 81.7%, respectively. The hospital mortality rates were 5.6% and 0%, respectively, and the complication rates were 46.3% and 46.3%, respectively. The 5-year overall survival rates were 98% and 91.5%, respectively. CONCLUSION In selected patients with biliary strictures and bilateral hepatolithiasis, partial hepatectomy associated with choledochoscopic lithotripsy is a safe and efficacious treatment, with a high immediate stone clearance rate, a low long-term stone recurrence rate and good long-term survival.

Abstract
AIM: To evaluate outcomes in patients with autosomal dominant polycyst liver disease (APLD) treated by combined hepatic resection and fenestration. A new classification was recommended to presume postoperative complications and long outcome of patients.
METHODS: Twenty-one patients with APLD were treated by a combined hepatic resection and fenestration technique. All patients were reviewed retrospectively, and clinical symptoms, performance status and morbidity were recorded. A new classification of APLD is recommended here.
RESULTS: All patients were discharged when free of symptoms. The mean follow-up time was 55.7 mo and three patients had a recurrence of symptoms at 81, 68 and 43 mo after operation, respectively. The overall morbidity rate was 76.2%. Two patients with Type B-IIand Type B-I developed biliary leakage. Four patients had severe ascites, including three with Type B-III and one with Type B-II. Nine patients had pleural effusion, including one with Type A-I; one with Type B-I; five with Type B-II; one with Type A-III and one with Type B-III. Three patients with Type B had recurrence of symptoms, while none with Type A had severe complications.
CONCLUSION: Combined hepatic resection and fenestration is an acceptable procedure for treatment of APLD. According to our classification, postoperative complications and long outcome can be predicted before surgery.
