Massive simultaneous hepatic and renal perivascular epithelioid cell tumor benefitted from surgery and everolimus treatment: A case report.

Background: Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal neoplasm that predominantly affects the kidney and uterus. The occurrence of this tumor in the liver, particularly with simultaneous involvement of the liver and kidney, is exceedingly uncommon. Pathological diagnosis is the gold standard.

Real-world efficacy of chidamide plus R-CHOP in newly diagnosed double-expressor diffuse large B-cell lymphoma.

Background: Approximately 20%-30% of diffuse large B-cell lymphoma (DLBCL) cases are classified as double-expressor lymphoma (DEL), characterized by the co-expression of the MYC and BCL2 proteins. However, the most effective therapeutic strategy for DEL remains unidentified.

Objectives: To evaluate the efficacy of a novel histone deacetylase inhibitor, chidamide, in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (CR-CHOP) in the treatment of DEL.

Damage Control Surgery Saves Patient with Gastric Lymphoma from Radical Gastrectomy.

The concept of damage control surgery was first introduced in the 1990s. It has great significance in the treatment for critically ill patients, which not only greatly improves survival rate, but also helps doctors avoiding misdiagnosis and mistreatment. Herein, we present a case of gastric perforation caused by neoplasm with critical condition of the patient.

Non-operative Treatment of Gastric Fistula after Splenectomy Combined with Pericardial Devascularisation in Portal Hypertension.

Portal hypertension may gradually lead to esophagogastric varices and splenomegaly in the decompensated stage of liver cirrhosis, which requires surgical treatment, if the disease worsens. Splenectomy with pericardial devascularisation is the routine surgery. One complex complication after splenectomy is upper gastric fistula which can seriously affect the perioperative recovery.

[Adsorption Characteristics of Norfloxacin by Biochars Derived from Reed Straw and Municipal Sludge].

Two types of biochars were prepared by pyrolyzing reed straw and municipal sludge at the temperature of 500 degrees C. The structure and properties of biochars were characterized by BET, scanning electron microscope (SEM), energy dispersive spectroscopy (EDS) and fourier transform infrared spectroscopy ( FTIR ). The effects of pH value, adsorption time, temperature and initial concentration of norfloxacin (NOR) on the adsorption behaviors were determined by single factor experiments, which were used to preliminarily discuss adsorption mechanism.

[Study on expression of Streptococcus suis serotype 2 sly gene, purification and activity of its product].

Objective: To clone and express Streptococcus suis serotype 2 (S. suis 2) sly gene for constructing an foundation on identification of S. suis 2 protective antigen.
