Gastric cancer is the fifth most diagnosed cancer worldwide and the third most common cause of cancer-related death. In recent decades, increasing application of next-generation sequencing has enabled detection of molecular aberrations, including fusions. In cases where tissue is difficult to obtain, cell-free DNA (cfDNA) is used for detecting mutations to identify the molecular profile of cancer. Here, we report a rare case of
fusion detected from cfDNA analysis in a patient with gastric cancer.

A 49-year-old female diagnosed with advanced gastric cancer in July 2019 received capecitabine and then combination chemotherapy of ramucirumab and paclitaxel, but ascites was detected. The therapy was switched to nivolumab, but disease progression was observed on a positron emission tomography/computed tomography scan in May 2020. Therapy was discontinued, and cfDNA next-generation sequencing was immediately evaluated. All genomic variants, including fusions, were analyzed from cfDNA. The following somatic alterations were detected from the patient's cfDNA an
frameshift mutation (NM_000038.5c.6579del, p.V2194fs) with variant allele frequency of 0.5%, an
amplification with a copy number of 17.3, and an
fusion with variant allele frequency of 45.3%. The site of the fusion was exon 24 of
fused to exon 10 of
The fusion was in-frame and considered to be protooncogenic. Although the patient refused to continue therapy, we suggest that
-targeted therapies be tried in such future cases.

The expanded applications of the cfDNA assay may open a new horizon in treatment of patients with advanced gastric cancer.

Pulmonary alveolar proteinosis (PAP) is a pulmonary syndrome wherein large volumes of phospholipid and protein-rich surfactants accumulate within the alveoli. PAP forms include primary (auto-immune PAP), secondary, and congenital. Nocardiosis is a form of suppurative disease induced upon infection with bacteria of the
genus. Clinically, cases of PAP complicated with
infections are rare, regardless of form. Unfortunately, as such, they are easily overlooked or misdiagnosed. We describe, here, the case of a patient suffering from simultaneous primary PAP and nocardiosis.

A 45-year-old Chinese man, without history of relevant disease, was admitted to our hospital on August 8, 2018 to address complaints of activity-related respiratory exertion and cough lasting over 6 mo. Lung computed tomography (CT) revealed diffuse bilateral lung infiltration with local consolidation in the middle right lung lobe. Subsequent transbronchial lung biopsy and CT-guided lung biopsy led to a diagnosis of primary PAP (granulocyte-macrophage colony-stimulating factor antibody-positive) complicated with nocardiosis (periodic acid-Schiff-positive). After a 6 mo course of anti-infective treatment (sul-famethoxazole), the lesion was completely absorbed, such that only fibrous foci remained, and the patient exhibited significant symptom improvement. Follow-up also showed improvement in pulmonary function and the CT imaging findings of PAP. No whole-lung lavage has been conducted to date. This case highlights that active anti-nocardia treatment may effectively improve the symptoms and alleviate PAP in patients with PAP and nocardia, possibly reducing the need for whole-lung lavage.

When evaluating patients presenting with PAP and pulmonary infections, the potential for nocardiosis should be considered.

'Splenosis' is defined as the autotransplantation of splenic tissue following trauma or surgery, usually in the form of intraperitoneal nodules. The proliferation of imaging techniques has resulted in increased unexpected discoveries of splenosis nodules, and achieving a differential diagnosis can be challenging. Nuclear medicine studies have been playing an increasingly important role in this process, but the clinical significance of asymptomatic nodules remains uncertain.

We present a case of pelvic splenosis in a 73-year-old man diagnosed 56 years after a splenectomy during a computed tomography (CT) follow-up for B-cell lymphoma, presenting intense contrast enhancement of an 18 mm nodule in the right recto-vesical space. 18F-fluorodeoxyglucose demonstrated weak metabolic activity. Since histological diagnosis was deemed necessary, the nodule was easily removed with robotically assisted laparoscopy, together with another 6 mm left a paracolic lesion. The latter was previously undiagnosed but retrospectively visible on the CT scan.

In a patient requiring differential diagnosis of splenosis nodules from lymphoma recurrence, the robotic approach provided a safe
removal with short hospitalization. The Da Vinci Xi robot was particularly helpful because its optics can be introduced from all ports, facilitating visualization and lysis of multiple intra-abdominal adhesions.

Emphysema pyelonephritis (EPN) is a very dangerous type of urinary tract infection. It is a lethal disease that develops rapidly and causes the patient to deteriorate rapidly, and it can easily lead to systemic infections and even sepsis. The incidence is extremely low, and it is prevalent in patients with diabetes. We here report a case of EPN in a non-diabetic patient with autosomal dominant polycystic kidney disease (ADPKD). We share the diagnosis and treatment procedure for this extremely rare condition to make this disease easier to identify and address early.

A 47-year-old woman presented to the emergency department of our hospital with a high fever and left back pain lasting 4 d. She had a history of autosomal dominant polycystic kidney and polycystic liver. She was diagnosed with left type I EPN and her vital signs deteriorated so quickly that she underwent an emergency operation in which a D-J tube was inserted into her left ureter on the second day after admission. Two months later, she underwent a second-stage flexible ureteroscopy and lithotripsy. Despite postoperative sepsis, she finally recovered after active symptomatic support treatment and effective anti-infective treatment.

Although EPN is more likely to occur in diabetic patients, for non-diabetic patients with ADPKD and upper urinary tract obstruction, the disease also causes rapid deterioration. Early and accurate diagnosis and timely removal of the obstruction by invasive means may be able to save the damaged kidney and the patient's life.

Behcet's disease (BD) is a chronic disease characterized by oral and vulvar ulcers as well as eye and skin damage and involves multiple systems. It presents as an alternating process of repeated attacks and remissions. Esophageal venous rupture and bleeding caused by BD is rarely reported at home and abroad. This paper reports a case of bleeding from oesophageal varices caused by BD, aiming to provide an additional dimension for considering the cause of bleeding from esophageal varices in the future.

A 38-year-old female patient was admitted due to a gradual increase in shortness of breath and chest tightness after the activity, and was admitted to our hospital for treatment. After admission, relevant examinations showed that the patient had multiple blood clots. Four days after admission, she suddenly experienced massive hematemesis. Emergency esophagogastroduodenoscopy revealed bleeding from esophageal and gastric varices. The patient had no history of viral hepatitis or drinking habits, and no history ide an additional dimension concerning the cause of bleeding from esophageal varices in the future.
Glioblastoma is the most common type of brain tumor and is invariably fatal, with a mean survival time of 8-15 mo for recently diagnosed tumors, and a 5-year survival rate of only 7.2%. The standard treatment for newly diagnosed glioblastoma includes surgery followed by concurrent chemoradiotherapy and further adjuvant temozolomide. However, the prognosis remains poor and long-term survival is rare. This report aimed to demonstrate a new therapeutic strategy for the treatment of glioblastoma.

A patient was referred to the Department of Neurosurgery with an intracranial space-occupying lesion with a maximum diameter of approximately 5 cm. The tumor was compressing functional areas, and the patient accordingly underwent partial resection and concurrent chemoradiotherapy. The imaging and pathological findings were consistent with a diagnosis of glioblastoma with oligodendroglioma differentiation (World Health Organization IV). The patient was finally diagnosed with glioblastoma. TNO155 order However, the patient discontinued treatment due to intolerable side effects, and was prescribed Kangliu pill (KLP) 7.5 g three times/d, which he has continued to date. Significant shrinkage of the tumor (maximum diameter reduced from about 3.5 to about 2 cm) was found after 3 mo of KLP therapy, and the tumor was further reduced to about 1 cm after 3 years. The patient's symptoms of headache, limb weakness, and left hemiplegia were relieved, with no side effects.

KLP has been a successful intervention for glioblastoma, and the current case indicates that traditional Chinese medicine may offer effective alternative therapies for glioblastoma.

Rhabdomyolysis is a serious complication of heat stroke. Unlike that in acute kidney injury, the risk of muscle bleeding in rhabdomyolysis is often ignored and can substantially increase
the widespread use of anticoagulants, leading to the formation of intramuscular hematoma.

During the summer, a middle-aged man and an elderly man were diagnosed with heat stroke, rhabdomyolysis, and acute renal impairment. Low-dose enoxaparin sodium was initiated for prophylaxis of deep vein thrombosis after the disease was stabilized with continuous renal replacement therapy. After that, the patients' hemoglobin decreased progressively, and no obvious intracranial, thoracic, digestive, or skin bleeding tendency was found. However, one of the patients had hip muscle pain, and computed tomography and color ultrasound confirmed that the patients separately had lumbar back and hip intermuscular hematoma. After discontinuation of anticoagulant drugs and monitoring of the steady increase in hemoglobin, the intermuscular hematomas were gradually absorbed.
