OBJECTIVE: To investigate the in vivo intervention and relative mechanism of Genistein (GEN) on tumor-associated inflammatory and tumor thrombophilia in lymphoma-bearing mice. METHODS: Forty female Balb/c mice aged 5-6 weeks were injected with murine-derived Pro B-cell lymphoma cell line 38B9 to establish a lymphoma mouse model, which was randomly divided into control group, tumor-bearing group, GEN drug intervention group and cyclophosphamide (CTX）drug intervention group. Histopathologic was used to evaluate the tumorigenesis. Tumor formation was observed, and tumor tissues were collected of HE and immunohistochemical staining. ELISA and flow cytometry were used to detect the expression of inflammatory factors and the changes of thrombus indices in plasma after intervention of GEN and Cyclophosphamide (CTX) respectively. Immunohistochemistry method was used to detect the expression of CD19 in tomor tissues of tummor bearing mice. RESULTS: After 14 days of tumor bearing, the mice were tumorigenic. The lymphoma cells were diffusely distributed in the tumor tissue and the expression of CD19 in the tumor tissue was positive. The inflammatory factors such as IL-6, NETs and CLEC-2, and thrombotic indices such as TF, FIB and D-D in lymphoma-bearing mice were significantly higher than those before tumor-injection and lower than those after drug-intervention (all P<0.05). The levels of CLEC-2 and D-D in GEN group were significantly lower than those in CTX group (P<0.05). CONCLUSION Tumor-associated inflammation and thrombophilia exist in lymphoma-bearing mice. GEN shows better anti-inflammatory and anti-thrombotic effects compared with CTX by interfering with tumor inflammatory factors.

AIM: To investigate the effect of orthokeratology lens on ocular surface and meibomian gland in children and adolescents of different ages.METHODS: A total of 120 cases(240 eyes)of myopic children and adolescents treated in the optometry clinic of our hospital from December 2020 to February 2021 were retrospectively selected, and they were divided into the orthokeratology group(60 cases, 120 eyes)and the frame glasses group(60 cases, 120 eyes)according to the myopia correction methods. The changes in ocular surface and meibomian gland after wearing glasses were analyzed, and those changes in patients of different ages were compared between the two groups.RESULTS: Corneal curvature decreased, non-invasive tear film break-up time(NIBUT)shortened and meibomian gland score increased at 3, 6, 9 and 12mo in the orthokeratology group after wearing lens, while lower tear meniscus height increased at 6, 9 and 12mo compared with that before wearing lens. In the frame glasses group, the lower tear meniscus height was higher at 6 and 9mo than that before wearing glasses(both P<0.05). At the same time point, the corneal curvature of the orthokeratology group was significantly lower than that of the frame glasses group at all time points, the NIBUT at 3, 9 and 12mo after wearing the lens was shorter than that of the frame glasses group and the meibomian gland scores were higher at 6, 9 and 12mo than those at the same time point in the glasses group(all P<0.05). After wearing lens for 12mo, the corneal curvature of the orthokeratology group at all ages was significantly lower than that of the frame glasses group, the NIBUT of the orthokeratology group at 8 to 12 years old and 13 to 15 years old was significantly lower than that of the frame glasses group, and the meibomian gland score was significantly higher than that of the frame glasses group(all P<0.05).CONCLUSION: Orthokeratology lens may affect the ocular surface and meibomian glands function, and the effects on ocular surface are more pronounced in children and adolescents under 12 years old. Therefore, younger children and adolescents could be prioritized for myopia correction with framed glasses, and then wearing orthokeratology lens when they get older.

Purpose: Systemic inflammatory response is a critical factor that promotes the initiation and metastasis of malignancies including pancreatic cancer (PC). This study was designed to determine and compare the prognostic value of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and fibrinogen-to-albumin ratio (FAR) in resectable PC and locally advanced or metastatic PC. Materials and Methods: Three hundred fifty-three patients with resectable PC and 807 patients with locally advan-ced or metastatic PC were recruited in this study. These patients were classified into a training set (n=758) and a validation set (n=402). Kaplan-Meier survival plots and Cox proportional hazards regression models were used to analyze prognosis. Results: Overall survival (OS) was significantly better for patients with resectable PC with low preoperative PLR (p=0.048) and MLR (p=0.027). Low FAR, MLR, NLR (p < 0.001), and PLR (p=0.003) were significantly associated with decreased risk of death for locally advanced or metastatic PC patients. FAR (hazard ratio [HR], 1.522; 95% confidential interval [CI], 1.261 to 1.837; p < 0.001) and MLR (HR, 1.248; 95% CI, 1.017 to 1.532; p=0.034) were independent prognostic factors for locally advanced or metastatic PC. Conclusion The prognostic roles of FAR, MLR, NLR, and PLR in resectable PC and locally advanced or metastatic PC were different. FAR showed the most prognostic power in locally advanced or metastatic PC. Low FAR was positively correlated with OS in locally advanced or metastatic PC, which could be used to predict the prognosis.

Psoriasis is considered a systemic disease associated with metabolic abnormalities, and it is important to understand the mechanisms by which metabolism affects pathophysiological processes both holistically and systematically. Metabolites are closely related to disease phenotypes, especially in systemic diseases under multifactorial modulation. The emergence of metabolomics has provided information regarding metabolite changes in lesions and circulation and deepened our understanding of the association between metabolic reprogramming and psoriasis. Metabolomics has great potential for the development of effective biomarkers for clinical diagnosis, therapeutic monitoring, prediction of the efficacy of psoriasis management, and further discovery of new metabolism-based therapeutic targets.

The mammalian epididymis not only plays a fundamental role in the maturation of spermatozoa, but also provides protection against various stressors. The foremost among these is the threat posed by oxidative stress, which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids, proteins, and nucleic acids. In mice, the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5 (GPX5) as a major luminal scavenger in the proximal caput epididymidal segment. Accordingly, the loss of GPX5-mediated protection leads to impaired DNA integrity in the spermatozoa of aged Gpx5

OBJECTIVE Glioblastoma multiforme (GBM) is the most malignant primary tumor of the central nervous system and is associated with a very poor prognosis. No further improvements in outcomes have been reported since radiotherapy-temozolomide therapy was introduced.Therefore,de-veloping new agents to treat GBM is important. This study aimed to evaluate the anti-tumor effect of evodiamine (Evo) on GBM cells, and to determine the underlying mechanisms involved. METHODS U251,LN229,HEB and PC12 cells were treated with various concentrations of evodiamine for 24 and 48 hours,cell viability was measured by MTT assay.The U251 and LN229 cells were treated with evo-diamine(0-10 μmol·L-1)for 24 h,and then stained with Hoechst 33258.An Annexin V-FITC Apoptosis Detection Kit was used to detect apoptosis in the cells.Reactive oxygen species(ROS)production was detected using dichlorofluorescein diacetate (DCFH-DA) staining. The changes in mitochondrial mem-brane potential (MMP) were assessed by JC-1 after cells were treated with evodiamine. The expres-sion levels of p-PI3K,PI3K,p-Akt,Akt,Bax,Bcl-2,p-p38,p38,p-JNK,JNK,p-ERK,ERK,Cytochrome c, Caspase-3, cleaved Caspase-3, PRAP, and cleaved PARP were measured by Western blot analy-ses. RESULTS According to MTT assay results, Evo significantly inhibited the cell proliferation in a time- and dose-dependent manner. Fluorescence microscopy and flow cytometry analyses revealed that Evo induced cell apoptosis in a concentration-dependent manner.Moreover,Evo induced reactive oxygen species (ROS) production and mitochondrial membrane potential (MMP) disruption. Finally, Evo induced apoptosis in cancer cells by suppressing PI3K/AKT signaling and inducing MAPK phos-phorylation(p38 and JNK,but not ERK)to regulate apoptotic proteins(Bax,Bcl-2,Cytochrome c,Cas-pase-3, and PARP). CONCLUSION In summary, Evo inhibits cell proliferation by inducing cellular apoptosis via suppressing PI3K/AKT and activating MAPK in GBM;these results indicate that Evo may be regarded as a new approach for GBM treatment.

OBJECTIVE: To improve the understanding of the clinical features of pulmonary cryptococcosis in non-human immunodeficiency virus (non-HIV) infection patients and reduce delay in diagnosis, or misdiagnosis. METHODS: The clinical features, imaging characteristics, laboratory examinations, treatment and prognosis of 34 cases of pulmonary cryptococcosis were retrospectively analyzed. The data were collected from Peking University First Hospital from June 1997 to June 2016. RESULTS: There were 34 cases diagnosed with pulmonary cryptococcosis, including 22 males and 12 females, aged from 20 to 75 years [average: (50.1±15.0) years]. There were 16 cases with host factors and (or) underlying diseases named immunocompromised group. In the study, 67.6% patients had clinical symptoms while 32.4% patients had no symptoms. The most common symptoms included cough, fever, chest pain, shortness of breath, and hemoptysis in sequence. Common chest imaging findings were patchy infiltrates, consolidation, single or multiple nodular or masses shadows. Among the 20 cases with cryptococcal capsular polysaccharide antigen detection, 19 were positive. Eleven cases underwent routine cerebrospinal fluid examination, and 3 cases complicated with central nervous system cryptococcal infection. At first visit, 24 cases were misdiagnosed, among which, 11 cases were misdiagnosed as lung cancer. The diagnosis of 15 cases was proved by percutaneous lung biopsy and 11 were confirmed by surgery, while 8 were diagnosed clinically. Then 11 cases were treated by surgical resection, and in median 4 years' followp, there was 1 case of recurrence. And 23 cases were treated with antifungal therapy, and in median 8 years' follow-up, 3 cases lost to the follow-up and 1 case of recurrence. Compared with normal immune group, immunocompromised patients had higher ages (P=0.017), more crackles (P=0.006) and more percentage of increase of peripheral white blood cells or neutrophils (P=0.003), but no significant difference in symptoms, imaging characteristics or hospitalization time. CONCLUSION There were no specific clinical symptoms and signs for pulmonary cryptococcosis in non-HIV patients. Diagnosis of pulmonary cryptococcosis depends on pathology. Percutaneous lung biopsy was mostly recommended for clinical highly suspected patients. Cryptoeoccal capsular polysaccharide antigen detection had a high sensitivity for the clinical diagnosis. Antifungal drug therapy was the major treatment, and the prognosis of the most patients was good.

OBJECTIVETo explore the surgical method and clinical outcome of modified osteotomy of olecranon for the treatment of inter-condylar fracture of humerus.

METHODSFrom May 2007 to December 2012, 32 patients of intercondylar fracture of humerus were treated surgically through the approach of modified osteotomy of olecranon. The patients were 21 males and 11 females with a mean age of 46.3 years (ranged 18 to 65 years). Nineteen fractures occurred on the right extremity and 13 on the left extremity. According to the AO classification, type C1 fracture was found in 7, C2 in 11 and C3 in 14. Five patients suffered from open fracture (Gustilo type Iin 3, type II in 2). Other fractures occurred in 6 patients and the primary injury of nerve occurred 6. The healing of the osteotomy was evaluated with physical examination and plain X-ray film, and the function of elbow was assessed according to Cassebaum scale.

RESULTSAll the patients were followed from 9 months to 5 years(average, 1.9 years). All the osteotomies healed at 7.4 weeks averagely after operation, and no nonunion, delayed union, fracture of ulna olecranon were found. Two cases had little pain on the elbow, heterotopic ossification occurred in 2 cases and cutting bone block loosed in 1 case. The function of the elbow showed excellent in 19 cases, good in 8, fair in 4 and poor in 1.

CONCLUSIONSThe use of the approach of modified olecranon osteotomy for surgical management of intercondylar fracture of humerus has some advantages, it provides satisfactory stability with simple technical procedures avoiding inter-articular invasion, and it facilitates rehabilitation exercises and providing good results with low complication rates.
