[Therapeutic effect of chlorhexidine combined with mechanical debridement on peri-implantitis and its influence on patients' SF-36 score].

Purpose: To study the effect of chlorhexidine combined with mechanical debridement on peri-implant inflammation and the influence on SF-36 score of patients.

Methods: One hundred patients with peri-implantitis admitted to Zhejiang Provincial People's Hospital from January 2015 to January 2019 were selected and randomly divided into control group and combined group with 50 cases in each group according to random number table method.Patients in both groups were treated with mechanical debridement, and patients in the combined group were gargled with chlorhexidine gargle apart from mechanical debridement.

[Analysis of factors affecting soft tissue infection after oral and maxillofacial debridement].

Purpose: To explore the factors affecting soft tissue infection after oral and maxillofacial debridement.

Methods: Fifty hundred patients with debridement were enrolled in this study from January 2013 to June 2016. The patients were divided into 2 groups according to soft tissue infection, 18 cases in infection group and 482 cases in non-infection group.

Giant cell tumor of the tendon sheath: Magnetic resonance imaging findings in 38 patients.

The present study aimed to investigate the value of magnetic resonance imaging (MRI) in the diagnosis of giant cell tumor of the tendon sheath (GCTTS), including localized (L-) and diffuse (D-) types. A total of 38 patients with GCTTS, including 31 with L-GCTTS and 7 with D-GCTTS, diagnosed by surgery and pathology, were retrospectively analyzed. All patients underwent MRI examination.

Metachronous Primary Adenocarcinoma of Lung During Adjuvant Imatinib Mesylate Therapy for Gastrointestinal Stromal Tumor of Stomach: A Case Report.

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor in gastrointestinal tracts; however, the synchronous or metachronous coexistence of GIST with additional primary malignancy is not common.Here, we present an unusual case of gastric GIST with metachronous primary lung adenocarcinoma diagnosed during his adjuvant treatment with oral receptor tyrosine kinase inhibitor imatinib mesylate (400 mg daily). After 6-month use of imatinib, the patient suffered from dry cough and dyspnea.

Use of digital subtraction angiography for assessment of digital replantation.

Objective: To assess the blood flow of the proper digital artery using digital subtraction angiography (DSA) in the early stage after replantation.

Methods: From January 2006 to October 2010, 27 anastomosed arteries in 27 replanted digits were included in the study. The patients included nine males and four females.

[Functional MR study of hepatic fibrosis].

The accurate diagnosis and staging of hepatic fibrosis is crucial for treatment and prognosis of liver disease. The current gold standard is liver biopsy, but it cannot be used in population-based screening, and has well known drawbacks if used for monitoring of disease progression or treatment results. Functional MR, as a non-invasive method, is increasingly used in hepatic fibrosis and became the current hot spot.

A large functional somatostatinoma in the pancreatic tail: atypical CT appearances.

Somatostatinomas are extremely rare endocrine tumors, and those with diameters above 2 cm are reported to increase the risk of metastasis significantly. We report a case of a large functional somatostatinoma in the pancreatic tail without metastases. A 46-year-old woman with a history of recurrent mild upper abdominal pain and diarrhea for 10 months was admitted to our hospital.

Primary hepatic sarcomas: CT findings.

Primary hepatic sarcomas are rare tumors that are difficult to diagnose clinically. Different primary hepatic sarcomas may have different clinical, morphologic, and radiological features. In this pictorial review, we summarized computed tomography (CT) findings of some relatively common types of hepatic sarcomas, including angiosarcoma, epithelioid hemangioendothelioma (EHE), liposarcoma, undifferentiated embryonal sarcoma (UES), leiomyosarcoma, malignant fibrous histiocytoma (MFH), and carcinosarcoma (including cystadenocarcinosarcoma).
