Cancer of unknown primary site in the mandibular region: A case report.

The diagnosis and treatment of cancer of unknown primary site (CUP) present with difficulties and produce a poor prognosis. The current study presents the case of a patient with CUP in the mandibular region was treated with docetaxel and lobaplatin chemotherapy, and vascular embolization of the tumor. The tumor size was markedly reduced and the patient's quality of life improved following radiotherapy. The present case report is accompanied by a discussion of the literature to contextualize the treatment regimen for patients with CUP. These findings will support current treatment practices, inform oncologists and benefit patients with cancer.

Case Report: A Case Report and Literature Review on Severe Bullous Skin Reaction Induced by anti-PD-1 Immunotherapy in a Cervical Cancer Patient.

Background: Anti-programmed cell death protein 1 (PD-1) has been successfully used in carcinomas treatment. However, it causes significant adverse effects (AEs), including cutaneous reactions, particularly the life-threatening severe bullous skin reactions (SBSR) and toxic epidermal necrolysis (TEN). Case summary: Herein, we described for the first time a case report of SBSR induced by anti-PD-1 therapy in a cervical cancer patient. In addition, we revised existing literature on anti-PD-1 induced cutaneous reactions. We reported a cervical cancer patient who was treated with four successive cycles of Sintilimab and Toripalimab injections and developed systemic rashes, bullae, and epidermal desquamation, which worsened and led to infection, eventually causing death after being unresponsive to aggressive treatments. Conclusion: Anti-PD-1 antibodies commonly cause skin toxicity effects, some of which may be deadly. Therefore, healthcare providers should observe early symptoms and administer proper treatment to prevent aggravation of symptoms.

Attitudes to Being Vaccinated Against COVID-19: A Survey of People With Epilepsy in China.

Objective: We conducted a survey to assess vaccination coverage, vaccination willingness, and variables associated with vaccination hesitancy to provide evidence on coronavirus disease (COVID-19) vaccination strategies. Methods: This anonymous questionnaire study conducted a multicenter, cross-sectional survey of outpatients and inpatients with epilepsy (PWE) registered in epilepsy clinics, in 2021, in 10 hospitals in seven cities of Shandong Province. Results: A total of 600 questionnaires were distributed, and 557 valid questionnaires were returned. A total of 130 people were vaccinated against COVID-19. Among 427 unvaccinated participants, 69.32% (296/427) were willing to receive the COVID-19 vaccine in the future, and the remaining 30.68% (131/427) were unwilling to receive vaccination. Most (89.9%) of the participants believed that the role of vaccination was crucial in response to the spread of COVID-19. A significant association was found between willingness to receive the COVID-19 vaccine and the following variables: age, marital status, level of education, occupation, residence, seizure type, and seizure control after antiepileptic drug therapy. It is noteworthy that education level, living in urban areas, and seizure freedom were significantly related to willingness to receive COVID-19 vaccination. Conclusions: Vaccination is a key measure for the prevention and control of COVID-19, and most PWE are willing to be vaccinated. Vaccine safety, effectiveness, and accessibility are essential in combatting vaccine hesitation and increasing vaccination rates.

Protective effect and mechanism of ginsenoside Rg1 in cerebral ischaemia-reperfusion injury in mice.

BACKGROUND: Ginsenoside Rg1 is regarded as one of main bioactive compounds responsible for pharmaceutical actions of ginseng with little toxicity and has been shown to have possibly neuroprotective effects. However, the mechanism of its neuroprotection for acute ischemic stroke is still elusive. The purpose of present study is thus to assess the neuroprotective effects of the ginsenoside Rg1 against neurological injury in a mice model of cerebral ischemia/reperfusion (I/R), and then to explore the mechanisms for these neuroprotective effects. METHODS: Mices were pretreated with ginsenoside Rg1 20,40?mg?kg?1?d?1, ig, for 7d, respectively, then subjected to cerebral ischenmia (middle cerebral artery occlusion) for 2?h and reperfusion for 22?h. The infarct volume and the neurological deficit were determined by TTC staining and Longa?s scoring, respectively. The protein expression of brain-derived neurotrophic factor (BDNF) was analyzed by Immunohistochemistry and Western blot, respectively. Interleukin-1? (IL-1?), tumor necrosis factor alpha (TNF-?) and interleukin-6 (IL-6) expression in serum was measured by ELISA kit. High-performance liquid chromatography (HPLC) was used to explore the contents of Glu and Asp. RESULTS: Compared with the ischemia/reperfusion group, ginsenoside Rg1 40?mg/kg group has significantly reduced infarct volume, neurological deficit scores (P?

[Value of contrast-enhanced ultrasound imaging in monitoring malignant tumor during argon-helium cryosurgery].

OBJECTIVE: To assess the value of contrast-enhanced ultrasound imaging in monitoring the therapeutic effect of argon-helium cryosurgical treatment of malignant tumors. METHODS: Before and after argon-helium cryosurgical treatment, 42 patients underwent contrast-enhanced ultrasound imaging, conventional ultrasound imaging and enhanced CT or magnetic resonance imaging (MRI) for examining the number of tumor foci and the size of necrotic areas. RESULTS: A total of 80 tumor lesions were detected by contrast-enhanced ultrasound imaging. Compared with conventional ultrasound imaging, contrast-enhanced ultrasound imaging detected a significantly greater number of tumors and the intratumoral necrotic areas (96 vs 19) as well as a significantly increased mean size of necrotic areas (5.7∓3.6 cm vs 2.8∓1.7 cm), showing no significant differences from the results by enhanced CT and MRI (94 and 5.5∓3.3 cm, P=0.872 and 0.978, respectively). The short-term therapeutic effect of argon-helium cryosurgery evaluated by contrast-enhanced ultrasound imaging were also similar to that assessed by enhanced CT or MRI (P=0.906). CONCLUSION: Contrast-enhanced ultrasound imaging has important values in monitoring malignant tumors during argon-helium cryosurgical treatment and in evaluating the short-term therapeutic effect of the treatment.
