ABSTRACT
Hepatocellular carcinoma (HCC) is the most common primary hepatic malign-ancy in clinic. The prognosis of patients remains extremely poor because of the high malignancy and easy recurrence and metastasis of HCC. In recent years, the roles of platelets in promoting the malignant progression of HCC have increasingly attracted much attention. It is known that platelets could promote HCC cells proliferation and invasion through tumor microenvironment. On the other hand, platelets are capable to promote HCC cells distant metastasis by facilitating tumor cells evasion of immune surveillance. Besides, the platelet-derived growth factors and proangiogenic factors are also involved in the proliferation, invasiveness, and neovascularization of HCC. In addition, patients with HCC normally have a background of cirrhosis, and it is still controversial that whether the thrombocytopenia by portal hypertension and hypersplenism can promote the malignant progress of HCC. In view of this, the diagnostic and prognostic value of platelet levels, as well as platelet-associated scores in HCC have increasingly become research focus. The authors elaborate the detailed mechanisms of platelets in malignant progression of HCC, and discuss the recent research progress of platelets as effective diagnostic or prognostic tools for the assessment of HCC, which is of great importance to optimize the current treatment regimen and explore novel therapeutic strategies against HCC.

In terms of alternative suggestion, 70.74%(162/229) of surgeons believed that it was necessary for the We-Media platforms to involve more doctors of different specialties, but 40.61%(93/229) of surgeons believed that relevant departments or associations should strengthen supervision under the current situation. In addition, 32.75%(75/229) of surgeons believed that the operation of We-Media platform requires more investment. The were 27.95%(64/229) of surgeons giving specific suggestions on running We-Media platforms, 7.81%(5/64) of which did not suggest a blind try.Conclusions:Most surgeons who open and operate We-Media platforms in China are faced with problems such as busy work, limited time and energy, low-income increase, and lack of professional promotion and maintenance teams and external support. Even so, there are still many surgeons who have achieved success through long-term persistence and high-quality content output, thus increasing the number of patient visits, improving their own ability and industry influence, and bringing a greater sense of professional achievement.
ABSTRACT
In October 2022, the European Society for the Study of the Liver (EASL) publishes officially the EASL Clinical Practice Guidelines on the management of cystic liver diseases, which covers the diagnosis, treatment, and management of hepatic cysts, mucinous cystic neoplasms of the liver, biliary hamartomas, polycystic liver disease, Caroli disease, Caroli syndrome and peribiliary cysts. Combined with the contrast-enhanced imaging examination, the guideline is of great significance for standardized diagnosis and treatment of hepatic cystic lesions. The authors interpret the guideline in detail, and systematically introduce the key points of assessment of various types of cystic liver disease and related recommendations for treatment. Meanwhile, the future applications and research directions are further prospected in order to provide more evidence basis for the clinical manage-ment and decision-making for patients with cystic liver diseases.
ABSTRACT
Objective To investigate the shaping rules of the femoral heads in the morphological perspective.The research objects are hips of normal children and children who have developmental dysplasia of the hip(DDH) and after closed reduction or limited open reduction.At the same time measuring and analyzing normal hip femoral head form changing with the children's age.Methods Collecting the DDH cases that after closed reduction and limited open reduction from June 2013 to December 2015.The follow-up period was more than 1 year.MRI images were collected before surgery,6 months after surgery,1 year after surgery,and 2 years after surgery.In addition,normal hip joint MRI images from 0 to 18 years old were collected for controlled study.Descriptive data on the affected side,healthy side and normal hip joint morphology of the hip dislocation were statistically analyzed.Results (1) The mean eccentricity of femoral head in normal hip decreased from (0.362 ±0.069) at 1-2 years to(0.141 ±0.028) at 18-19 years.(2) The eccentricity of femoral head before closed reduction and limited open reduction were both greater than those of healthy side.There was no significant difference in the eccentricity of the femoral head between the healthy side and the affected side at 1 year after closed reduction (P =0.211).There was no significant difference in the diameter of the bilateral femoral heads (P =0.871).The eccentricity of the bilateral femoral heads remained different at 2 years after limited open reduction (P =0.028),and the diameter of the affected femoral head exceeded the healthy side 1 year after surgery (P =0.001).Conclusion The shape of the femoral head of normal children gradually approaches the spherical shape with age.One year after closed reduction of DDH,the shape and size of the affected femoral head are close to the healthy side,and the femoral head of the affected side increases more than the healthy side in 1 ～ 2 years after open reduction and the morphology is still different.
ABSTRACT
Hepatocellular carcinoma (HCC) is one of the most frequently diagnosed malignancies and the third leading cause of cancer-related deaths in the world.China is known as the country with the highest prevalence of liver cancer,and more than half of the cases of HCC worldwide occur in China.Recently,immunotherapy for HCC has drawn wide attention owing to its satisfying effects on specific solid malignancies.Both basic and clinical researches on immunotherapy for HCC have made some progress,which has laid a foundation for future clinical application of immunotherapy in HCC patients.The main immunological strategies for HCC include adoptive immunotherapy,indirect immunotherapy,and indirect non-immunological therapy.Despite the potential benefits for HCC,challenges and obstacles of immunotherapy remain,such as the self-tolerance immune mechanism of the liver and the lack of ideal target antigen.In a word,the application of immunotherapy for HCC in clinical practice is a tough task to accomplish and a long way to go.
ABSTRACT
In the twentieth session of the National Clinical Oncology Conference and 2017 annual meeting of Chinese Society of Clinical Oncology (CSCO),many progressions have been made in the diagnosis and treatment of primary liver cancer.(1) A preliminary report of the real world study of primary liver cancer in China was released.(2) Emerging diagnostic techniques and predictive models can detect preoperative liver cirrhosis and risk of postoperative liver failure in patients with hepatocellular carcinoma (HCC).(3) Photodynamic diagnostic technology can ensure histological clearance with negative surgical margin and preserve as much liver parenchyma as possible.(4) Lenvatinib is expected to be the first-line targeted drug for the treatment of patients with unresectable HCC following sorafenib.(5) Immunotherapy with Nivolumab and Pembrolizumab is still a hot topic in the field of HCC management.(6) Though a vast heterogeneity of patterns of liver resection for HCC exists between two large centers from the East and the West,their surgical safety and long-term efficacy are actually comparable.(7) Routine lymphadenectomy,active surgical intervention for patients with late-stage tumors,ensuring the negative margins of resection and comprehensive treatment of postoperative recurrence are expected to improve the long-term outcomes of intrahepatic cholangiocarcinoma (ICC).
ABSTRACT
Neonatal visceral injury have high clinical incidence and it is hard to make clinical diagnosis early by routine inspection. In recent years,researches have shown that neonatal multiple organs damage can be diagnosed early by analyzing some special components in urine. Besides,urine analysis is a noninvasive examina-tion method and it is suitable for clinical promotion. This paper enumerates the application of neonatal urine ex-amination in the early diagnosis of kidney damage,bronchial pulmonary displasia,patent ductus arteriosus,hy-poxic ischemic encephalopathy and metabolic disease.
