Objective:To improve the understanding of patients with diffuse large B-cell lymphoma (DLBCL) with pulmonary cryptococcosis.Methods:The clinical data of 1 DLBCL patient with pulmonary cryptococcosis in the Central Hospital of Fengxian District of Shanghai in May 2023 were retrospectively analyzed, and the relevant literatures were reviewed.Results:This 75-year-old female patient was asymptomatic after 2 cycles of R-CHOP chemotherapy. The high-resolution CT of lung showed that lung nodules were progressively enlarged. Antibacterial treatment was ineffective. Pulmonary cryptococcosis was confirmed by bronchoalveolar lavage fluid (BALF) targeted high-throughput sequencing (tNGS) and cryptococcus capsular antigen (CrAg) detection. The central nervous system was not involved. And the long-term adequate-dose fluconazole was prescribed for 6 months, and the treatment against lymphoma was given synchronously. The lung nodule lesions reduced after antifungal therapy for 1 month. The lung nodules disappeared after the follow-up of 6 months after completion of final chemotherapy. The evaluation of lymphoma indicated complete remission.Conclusions:Pulmonary cryptococcosis occurs insidiously and shows no specific symptoms; its imaging manifestations are variable and routine anti-infection is ineffective. Immunochemotherapy for lymphoma patients is a high-risk factor for cryptococcal infection. tNGS and CrAg testing for BALF are effective methods of the confirmed diagnosis. The early and long-term adequate-dose antifungal treatment is the key to preventing the recurrence or progression.

Objective: To detect the expression of non-coding RNA snord105b in gastric cancer (GC) tissues, sera and cell lines, and its correlation with clinicopathological characteristics of patients with GC as well as its effect on the proliferation of GC cells. Methods: One hundred and twenty pairs of GC tissues and corresponding para-cancerous tissues from patients, who underwent surgery at Department of Surgery, the Fourth Hospital of Hebei Medical University between 2016 and 2017, were collected for this study. The presurgical sera samples from GC patients (n=50) and peripheral venous blood samples from healthy donors (n=30), as well as five gastric cancer cell lines (SGC-7901, AGS, MGC-803, BGC-823, HGC-27) and gastric mucosa normal epithelial GES-1 cells were also obtained. qPCR assay was adopted to detect the expression of snord105b in GC tissues, sera and cell lines. The correlation between snord105b and patients’clinicopathological features was investigated. MTS assay was adopted to detect the effect of snord105b silence or over-expressionon in vitro proliferation of four GC cells. Results: qPCR assay demonstrated that the expression of snord105b in GC tissues, sera and cell lines were significantly higher than that of para-cancerous tissues, sera from healthy donors and GES-1 cells (all P< 0.05). Expression level of snord105b was obviously associated with age,tumor size, differentiation and TNM stages of patients (all P<0.05). MTS assay demonstrated that knockdown of snord105b could suppress the proliferation of GC cells (P< 0.05), while forced-expression of snord105b could promote the proliferation of GC cells (P< 0.05). Conclusion: non-coding RNA snord105b aberrantly expressed in GC tissues, sera, and cells, and its expression was obviously correlated with patients’age, tumor size, differentiation and TNM stages. Snord105b could significantly promote the proliferation of GC cells, which may be used as a potential clinical biomaker for early diagnosis and prognosis of GC.

To evaluate the influence and long-term effects on systemic and local inflammation responses in rat with stable chronic obstructive pulmonary disease (COPD) treated with traditional Chinese medicine (TCM) for regulating and invigorating the lung and kidney, including invigorating the lung and spleen (Bufei Jianpi) therapy, supplementing the lung and kidney (Bufei Yishen) therapy, and nourishing qi and kidney (Yiqi Zishen) therapy.

Objective To investigate clinical features and extent of gastric, liver and pancreatic damage of primary Sjgren syndrome(pSS). Method Clinical data of 152 pSS patients with gastric,liver and pancreatic damage were analyzed.Results The occurence of chronic atrophic gastritis(CAG),the most commonly seen gastic involvment in pSS,was 77.8%.The atrophic leisions differed with patient's age.Compared with the control group, the atrophy and intestinal metaplasia of the pSS patients with CAG were milder(P
