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
Hepatocellular carcinoma (HCC) has a high incidence and low five-year survival rate in China. There is a lack of effective therapeutic approaches available for unresectable patients with advanced HCC. Recently, the development of targeted and immunotherapy agents and their application in the therapy of various solid tumors have brought new options and benefits to patients with advanced HCC. Companion diagnostics (CDx) emerged with the development of targeted agents, and its roles in selecting eligible patients for specific targeted/immunotherapy agents and improving prognosis are getting more prominent. This article focuses on the CDx technologies and applications related to HCC targeting and immunotherapy, in order to provide inspiration for the precise diagnosis and treatment of HCC.

Abstract
BACKGROUND Anastomotic leakage is one of the most serious complications that can occur after laparoscopic-assistedsphincter-preserving surgery for middle- and low-grade rectal cancer. OBJECTIVES To explore the cause, prevention, and treatment of anastomotic leakage after sphincter-preserving surgery for middle- and low-grade rectal cancer under laparoscopy. METHODS The clinical data from patients with mid- and low-grade rectal cancer who underwent laparoscopic-assistedanus-preserving surgery in the anorectal surgery department of our hospital have been analyzed. Patients with a definite diagnosis, indications for laparoscopic surgery, and sphincter-preserving surgery were included in the analysis, and patients with a protective loop ileostomy and laparotomy were excluded. RESULTS Among the 126 patients with middle- and low-grade rectal cancer undergoing sphincter-preserving surgery under laparoscopy. There were 75 male patients and 51 female patients, ranging in age from 37 to 89 years old, with an average age of 60.2 ± 6.7. The distance from the lower edge of the rectal tumor to the anal edge was ≤10 cm. 6 developed anastomotic leakage after the operation (leakage rate of 4.7%). Moreover, turbid purulent fluid was drained from the abdominal drainage tube in three patients on the third and fourth days after the operation, and the abdominal drainage tube drained serous drainage in three more patients on the fifth and sixth days, with signs of peritonitis appearing locally. All patients received continuous flushing and negative pressure drainage with a self-made double cannula and symptomatic treatment, and all were cured and discharged. CONCLUSION Many factors can cause anastomotic leakage after this operation, and adequate perioperative preparation, meticulous operation during surgery, and careful postoperative management are key factors in preventing it.

Abstract
Objective To evaluate the safety and feasibility of single-incision laparoscopic
surgery+1 (SILS+1) radical resection of sigmoid and upper rectal cancer. Methods The clinical data of 30 consecutive patients with sigmoid and upper rectal
cancer who underwent SILS+1 radical resection between October 2018 and
January 2020 in our hospital were retrospectively analyzed. An initial 5-cm
periumbilical transverse incision was made. Then, a multiport device was
placed in the umbilical incision. Two 10-mm ports were used for laparoscope
insertion, and the other two ports were used for laparoscope device
insertion. A 12-mm trocar was placed in the right lower abdominal quadrant
under laparoscopic view and served as the surgeon’s dominant operating
channel. Results All operations were performed successfully without conversion to conventional
laparoscopic surgery or open operation. Three patients developed
postoperative complications: one patient developed ileus, one developed
postoperative bleeding, and one developed wound infection. There were no
perioperative deaths. Conclusions The safety and feasibility of SILS+1 radical resection of sigmoid and upper
rectal cancer was established by experienced surgeons in our study. However,
further studies are needed to demonstrate the advantages of this procedure
compared with the benefits of conventional laparoscopic surgery.

Abstract
OBJECTIVE To investigate the clinical use of a large C suture in the procedure for prolapse and hemorrhoids (PPH) for treatment of mixed hemorrhoids. METHODS Patients with mixed hemorrhoids (grade III or IV) who underwent treatment with a large C suture during PPH in the Affiliated Hospital (Group) of Putian University from 1 April 2018 to 31 March 2019 were enrolled in this retrospective study. The incidences of anastomotic stenosis and anastomotic hemorrhage after the operation were observed. RESULTS The study population comprised 126 patients (46 men and 80 women) ranging in age from 30 to 78 years (mean, 46.1 ± 2.5 years). Of these patients, 60 had circular mixed hemorrhoids, 36 had grade III circular internal hemorrhoids, and 30 had grade IV circular internal hemorrhoids. The onset time among all patients ranged from 0.5 to 25 years. All patients underwent 6 months of postoperative follow-up. None of the patients with mixed hemorrhoids developed anastomotic stenosis, although two patients developed secondary anastomotic bleeding. CONCLUSION Placement of a large C suture during PPH is a reliable technique for treatment of mixed hemorrhoids. It is simple, effective, and applicable and can be helpful for a large number of patients in primary hospitals.

Abstract
Objective: To explore the clinical value of serum des-γ-carboxy prothrombin (DCP) in predicting hepatocellular carcinoma recurrence after liver transplantation. Methods: A total of 115 cases with hepatocellular carcinoma who underwent liver transplantation in Zhongshan Hospital Affiliated to Fudan University from October 2016 to December 2018 were retrospectively analyzed. Receiver operating characteristic curve analysis, Mann-Whitney U test, Kaplan-Meier method, Log-Rank test, χ2 test, univariate and multivariate Cox regression analysis and other statistical methods were used to explore the value of DCP in predicting tumor recurrence after liver transplantation and its correlation with clinicopathological characteristics. Results: The preoperative serum DCP level in recurrent population after liver transplantation was significantly higher than that in non-recurrent population (P < 0.001). The optimal cut-off value of preoperative DCP for predicting recurrence was 200mAU/ml with the use of receiver operating characteristic curve. The sensitivity, specificity, Youden's index and the receiver operating characteristic curve was 87.90%, 57.30%, 0.452, and 0.726, respectively. Survival analysis results grouped by this cut-off value showed that patients with preoperative DCP ≥200mAU/ml had a higher probability of recurrence (P < 0.001). Further, subgroup survival analysis showed that patients with preoperative DCP≥200 mAU/ ml had a higher probability of recurrence than other cases of alpha-fetoprotein negative subgroup, cumulative tumor diameter ≤ 9 cm subgroup and Milan criteria subgroup (P < 0.05). Cox regression analysis showed that preoperative DCP≥200 mAU/ ml (P = 0.017) and cumulative tumor diameter > 9 cm (P = 0.014) was an independent risk factor for recurrence after liver transplantation. χ (2) test results showed that preoperative serum DCP level was correlated with gender, serum gamma glutamyltransferase level, serum alpha fetoprotein level, cumulative tumor diameter, vascular invasion, tumor differentiation and liver cancer transplant criteria (P < 0.05). Conclusion: Preoperative serum DCP can be used as a supplement to the existing liver cancer transplant criteria to predict hepatocellular carcinoma recurrence after liver transplantation. In addition, the accurate screening of patients with low risk of HCC recurrence after liver transplantation can improve the prognosis and efficacy of liver transplant patients.

Abstract
Liver cancer is one of the most common malignant tumors and currently ranks the fourth in morbidity rate and the second in mortality rate in China. At present, the main clinical treatmentmethod is surgical treatment and other treatments, such as interventional therapy, local radiotherapy and chemotherapy, serve as supplementary treatment methods. However, due to the occult incidence of liver cancer, most patients have entered the advanced stage at the time of diagnosis and lack effective treatment methods, resulting in low overall survival rate, high mortality rate and poor prognosis. Immunotherapy, especially cellular immunotherapy, as an emerging cancer treatment method, can directly kill tumor cells or stimulate the anti-tumor immune response by isolating and activating immune effector cells. Common methods include chimeric antigen receptor T cells, tumor-infiltrating lymphocytes and cytokine-induced killer cells, etc. Recently, cellular immunotherapy has become a research hotspot because it can enhance the immune function, reduce the recurrence rate and prolong the survival time of patients. This article reviews the advances in the study of cellular immunotherapy in the clinical application of liver cancer.

Abstract
Objective: To compare the histologic features of immune-mediated hepatitis (IMH) due to immune checkpoint inhibitors (ICIs) monotherapy and combined ICIs anti-angiogenesis tyrosine kinases (TKIs) targeted therapy. Methods: Twenty-one IMH patients who had liver biopsy during ICIs treatment in Zhongshan Hospital of Fudan University from 2015 to 2019 were included. Among them, ten were treated with ICIs monotherapy, and 11 were treated with combined ICIs and anti-angiogenesis targeted therapy. The histologic features of IMH were assessed by HE staining and PD-L1/2 was evaluated by immunohistochemical staining. Results: Patients treated with monotherapy ICIs presented with different levels of lobular hepatitis and portal inflammation. Besides, there were also cholangitis, endothelialitis, Kupffer cells activation and peliosisi hepatitis. Eight cases (8/10) showed mild and two cases (2/10) showed moderate hepatic injury. As for patients receiving combined ICIs and TKIs therapy, the extent of IMH was more severe, with four cases (4/11) showing moderate-severe liver injury, with confluent or bridging necrosis, portal inflammation, cholangitis, interface hepatitis. Among these, one patient developed acute severe hepatitis with massive hepatocyte necrosis and died of multisystem dysfunction. In those cases with severe liver injury, many CD8 positive lymphocytes aggregated in the portal area and hepatic sinusoid, and PD-L1 was expressed in many endothelial cells. There were both 2 cases of death in ICIs monotherapy and combination therapy group. Among the latter group, 1 patient developed acute severe hepatitis with massive hepatocyte necrosis and died of multisystem dysfunction. Conclusion: Compared with ICIs monotherapy, combined ICIs and anti-angiogenesis targeted TKIs therapy may cause overlapping hepatic injury, leading to severe IMH.

Abstract
Objective: To investigate the efficacy of first-line administration of generic dasatinib or first-generation TKI (imatinib) in patients with Philadelphia chromosome positive acute lymphoblastic leukemia (Ph(+) ALL) treated by hematopoietic stem cell transplantation (HSCT). Methods: Clinical features and prognoses of 63 newly diagnosed Ph(+) ALL patients from Jan 2014 to June 2017 treated by HSCT combined with first-line administration of generic dasatinib or imatinib were retrospective analyzed. Results: Of 63 Ph(+) ALL patients, 31 cases were administered generic dasatinib, and the other 32 ones imatinib. Complete remission (CR) rates at the fourth week of induction therapy in generic dasatinib and imatinib groups were 96.8% and 93.8% (P=1.000) , respectively. Meanwhile major molecular response (MMR; BCR-ABL/ABL reduce 3log) rates were 41.9% and 43.8% (χ(2)=0.021, P=0.884), respectively. Relapse rates before transplantation were 6.5% and 12.5% (P=0.672), respectively. MMR rates before HSCT were 83.9% and 68.8% (χ(2)=1.985, P=0.159), respectively. The 20-monthes overall survival (OS) rates of generic dasatinib and imatinib groups were 95.5% and 76.5% (χ(2)=0.990, P=0.320) respectively; 20-monthes event-free survival (EFS) rates were 93.5% and 61.4% (χ(2)=5.926, P=0.015), respectively. Statistically significant differences of EFS were reached. Multiple factors analysis showed that generic dasatinib (HR=0.201, 95% CI 0.045-0.896, P=0.035) and MMR before transplantation (HR=0.344, 95% CI 0.124-0.956, CI=0.041) could improve EFS. Conclusions: First-line administration of generic dasatinib could improve EFS for Ph(+)ALL patients treated by HSCT when compered with imatinib.

Abstract
Objective: To investigate the incidence, clinical, biochemical and gene mutation characteristics of short chain acyl-coenzyme A dehydrogenase deficiency (SCADD). Method: From January, 2009 to October, 2015, a retrospective analysis of the urine organic acids and acyl-coenzyme A dehydrogenase (ACADS) gene mutation characteristics of patients diagnosed as SCADD by newborn screening using tandem mass spectrometry in Department of Genetics and Metabolism (Newborn screening Center of Zhejiang Province), Children's Hospital, Zhejiang University School of Medicine. Dietary guidance, life management and supplementation of L-carnitine were conducted, and growth and intelligence development were observed during follow-up among the SCADD patients. Result: A total of 1 430 024 neonates, seventeen cases were diagnosed with SCADD with an incidence of 1/84 117. All patients had no clinical symptoms, and intelligence and physical development were normal. Blood butylacyl-carnitine (C4) levels and the ratios increased, C4 0.713.14 μmol/L(reference value 0.03-0.48 μmol/L), C4/C2 0.07-0.23(reference value 0.01-0.04), C4/C3 0.65-2.04(reference value 0.05-0.39). Thirteen with increased urinary ethyl malonic acid (9.30-90.99 mg/g creatinine (reference value 0-6.20 mg/g creatinine )), one patient was accompanied by increased methyl succinic acid (12.33 mg/g creatinine(reference value 0-6.40 mg/g creatinine)), one subject with increased acetylglycine (3.52 mg/g creatinine(reference value 0-0.70 mg/g creatinine)). A total of 13 known mutations were detected in the ACADS gene, 1 homozygous mutation (c.1031A>G), the others are compound heterozygous mutations. One frameshift mutation (c.508_509delGC) and 12 missense mutations were detected. Common mutation were c. 1031A>G(35.3%), c. 164C>T(20.6%) and c. 991G>A(11.8%). SCADD in newborn screening program had no clinical symptoms and normal growth development after 8-42 months follow-up. Conclusion: Cases with SCADD had no clinical symptoms with an incidence of 1/84117. The c. 164C>T and c. 1031A>G may be the common mutations.

Abstract
OBJECTIVE To investigate the clinical efficacy and outcomes of two separate vertical wiring combined with tension band and Kirschner-wire plus cerclage wire in the treatment of displaced inferior pole fractures of the patella. METHODS From January 2013 to January 2015, 15 consecutive patients (mean age 54.5 years) with inferior pole fractures of the patella were retrospectively included in this study. All the patients underwent open reduction and internal fixation by separate vertical wiring combined with tension band and Kirschner-wire plus cerclage wire through longitudinal incision, 4.5 d (range: 3.1-5.9 d) after initial injury. A safety check for early knee range of motion was performed before wound closure. The complications including infection, nonunion, loss of fixation and any wire breakage or irritation from implant were recorded. Anteroposterior and lateral views of the knee joint obtained during the follow-up were used to assess bony union based on the time when the fracture line disappeared. At the time of the final outpatient follow up, functional evaluation of the knee joint was conducted by Bostman system. RESULTS The follow-up time was 13.1 months (range: 12-19 months) after surgery on average, immediate motion without immobilization in all the cases was allowed and there was no case of reduction loss of the fracture and wire breakage. There was no case of irritation from the implant. At the final follow-up, the average range of motion (ROM) arc was 126.7° (range: 115°-140°), the average ROM lag versus contralateral healthy leg was 10.3° (range: 0°-35°). The mean Bostman score at the last follow-up was 28.9 (range: 27-30), and graded excellent in most cases. CONCLUSION Two separate vertical wiring is an easy and effective method to reduce the displaced inferior pole fracture of patella. Augmentation of separate vertical wiring with tension band and Kirschner-wire plus cerclage wire in these patients provides enough strength to protected the early exercise of the knee joint and uneventful healing. By this surgical treatment, excellent results in knee function can be expected for cases of displaced inferior pole fractures of the patella.

Abstract
OBJECTIVE To optimize the dose of lipid infusion in treatment of patients with acute dexmedetomidinepoisoning, in order to further guide the rational use of medication in clinical practice. METHODS A total of 80 patients with acute dexmedetomidinepoisoning were admitted in this study from January 2012 to October 2014 at our hospital and divided into three groups based on the intensity of poisoning, including: slight poisoning (28 cases), moderate poisoning (32 cases) and severe poisoning (20 cases). Patients in each group were given 10% lipid infusion or 20% lipid infusion for treatment.Stable blood dexmedetomidineconcentrations of patients in pre-treatment and at different time points after treatment (pre-treatment and 0.5, 1, 2, 5, 10, 20 h after treatment) and the length of hospital stay, awake time in each group were investigated and compared.Ramsay sedation scores were recorded and compared in different time points (0.5 h before treatment and 2, 5, 20 h after treatment) in each group for different treatments.Side effects and complications were recorded, and follow-up was conducted during 1-3 d post discharge to record the recovery condition in patients. RESULTS In each group, patients receiving 20% lipid infusion waked earlier than those receiving 10% lipid infusion.And the hospitalization duration for patients receiving 20% lipid infusion was significantly shorter than those receiving 10% lipid infusion [(4.6±1.6) h vs (6.7±2.0) h, (2.6±0.4) d vs (4.0±0.6) d, P<0.05]. The Ramsay sedation scores were significantly lower for patients receiving 20% lipid infusion than those receiving 10% lipid infusionat 2 h and 5 h after treatment in each group [(3.4±0.3) vs (4.7±0.4), (2.6±0.3) h vs (3.5±0.3) h, P<0.05]. The stable plasma concentrations of dexmedetomidine were gradually reduced after the treatment, and which were lower when compared with the theoretical metabolic concentration.What's more, the plasma concentrationsat 1 h, 2 h and 5 h after treatment were significantly lower for patientsreceiving 20% lipid infusion than those receiving 10% lipid infusion in each group (P>0.05). All patients in our study were cured and discharged without severe side effects and complications, and follow-ups showed that no patients showed evidence of rebound phenomenon. CONCLUSIONS Different concentrations of lipid infusionare safe and effective in relieving the intensity of dexmedetomidinepoisoning, and promoting the clinical recovery.What's more, the therapeutic efficacy of 20% lipid infusion is greater than 10% lipid infusion.

Abstract
Ginger proteases are used as milk coagulants in making a Chinese traditional milk product (Jiangzhinai or Jiangzhuangnai), suggesting their potential as a source of rennet substitute that might be applicable in the modern dairy industry. In this study, ginger proteases were extracted from fresh ginger rhizome by using phosphate buffer and subsequently purified by ion exchange chromatography. Ginger proteases, all with a molecular weight around 31 kDa, were found to exist in 3 forms with isoelectric point values around 5.58, 5.40, and 5.22, respectively. These enzymes had very similar biochemical behavior, exhibiting optimal proteolytic activity from 40 to 60 °C and maximum milk clotting activity at 70 °C. They were capable of hydrolyzing isolated α(S1)-, β-, and κ-casein, of which α(S1)-casein was most susceptible to the enzyme; κ-casein was hydrolyzed with a higher specificity than α(S1)- and β-casein. In addition, the ginger proteases exhibited a similar affinity for κ-casein and higher specificity with increasing temperature. Gel electrophoresis and mass spectra indicated that Ala90-Glu91 and His102-Leu103 of κ-casein were the preferred target bonds of ginger proteases. The milk clotting activity, affinity, and specificity toward κ-casein showed that ginger protease is a promising rennet-like protease that could be used in manufacturing cheese and oriental-style dairy foods.

Abstract
Thyroid hormone is an important factor for proper development of the mammalian brain. Perinatal hypothyroidism leads to long-term behavior and neuromotor competence alterations in humans and animals. Our study aimed to investigate the effects of perinatal hypothyroidism on behavior changes of rat pups and its relation with the apoptosis of hippocampus neurons. Behavior tests were taken to evaluate the effects caused by perinatal hypothyroidism. TUNEL staining was used to analyze the apoptosis of neurons on CA3 region of hippocampus. The study suggested that perinatal hypothyroidism affects behavior development, as well as leading to the decrease in spatial learning and memory capability. This condition can be improved with hormone substitute treatment. Furthermore, the changes of learning and memory capability are closely related to the increasing number of apoptotic neurons in the hippocampus.
