Objective: First-line bevacizumab plus carboplatin and paclitaxel (CP) is approved for stage III/IV ovarian cancer treatment following initial surgical resection, based on global phase III GOG-0218 and ICON7 trials. This study evaluated the efficacy and safety of bevacizumab + CP as first-line ovarian cancer therapy in Chinese patients. Methods: Patients with newly diagnosed, International Federation of Gynecology and Obstetrics (FIGO) stage III/IV epithelial ovarian, fallopian tube, or primary peritoneal cancer post-primary surgery were randomized 1:1 to receive 6 cycles of CP with bevacizumab/ placebo, followed by bevacizumab/placebo maintenance until unacceptable toxicity or disease progression. Primary endpoint was investigator-assessed progression-free survival (PFS). Stratification factors were FIGO stage and debulking status (stage III optimally debulked vs stage III suboptimally debulked vs stage IV) and Eastern Cooperative Oncology Group performance status (0 vs 1 or 2). Results: Of randomized patients, 51 received bevacizumab + CP and 49 received placebo + CP. Median PFS was 22.6 months with bevacizumab + CP (95% confidence interval [CI]=18.6, not estimable) and 12.3 months (95% CI=9.5, 15.0) with placebo + CP (stratified hazard ratio=0.30; 95% CI=0.17, 0.53). Treatment-related grade 3/4 adverse events occurred in 46 of 49 (94%) patients receiving bevacizumab + CP, and 34 of 50 (68%) receiving placebo + CP. Conclusion Bevacizumab + CP showed clinically meaningful improvement in PFS vs placebo + CP, consistent with GOG-0218 results. Safety data were aligned with the known bevacizumab safety profile. These results support first-line bevacizumab + CP therapy in Chinese patients with ovarian cancer.

Objective To identify the independent risk factors of cognitive impairment(CI)in patients with cerebral small vessel disease(CSVD)and construct a clinical prediction model.Methods Patients with CSVD who were hospitalized in the First Affiliated Hospital of Xi'an Jiaotong University from January 1,2017 to December 31,2022 were retrospectively enrolled,and were divided into a group with cognitive impairment(CSVD-CI group,n=83)and a group without cognitive impairment(CSVD-NCI group,n=164)according to the mini-mental state examination(MMSE).The influence factors of cognitive impairment were screened by logistic regression.The clinical prediction model of the nomogram was further developed based on the screened factors,and the efficacy of the model was tested.Results Compared with patients in the CSVD-NCI group,patients in the CSVD-CI group had higher neutrophil/lymphocyte ratio(NLR)(3.03±2.56 vs 2.33±1.34)and(1.58±0.27 vs 1.49±0.28),and a lower estimated glomerular filtration rate[eGFR:88.59±16.59 ml/(min·1.73m2)vs 94.02±12.45 ml/(min·1.73m2)],with significant differences(t=2.282,2.426,2.689,all P＜0.05).Compared with patients in the CSVD-NCI group,patients in the CSVD-CI group had lower proportion of males(43.4％vs 67.7％)and level of education(2.13±1.50 vs 2.86),and the differences were significant(x2=13.516,t=4.283,all P＜0.05).NLR(OR:1.20,95％CI:1.01～1.43),sex(OR:0.43,95％CI:0.24～0.79),eGFR(OR:0.97,95％CI:0.95～0.99)and education degree(OR:0.72,95％CI:0.57～0.91)were the impact factors for cognitive impairment in CSVD patients.The nomogram prediction model based on these four factors had good efficacy in predicting cognitive impairment(AUC=0.704,95％CI:0.633～0.766).Conclusion The nomogram constructed in this study has moderate accuracy and clinical utility in predicting the occurrence of cognitive impairment in CSVD patients.

Hymenolepis nana and Hymenolepis diminuta are globally widespread zoonotic cestodes. Rodents are the main reservoir host of these cestodes. Brown rats (Rattus norvegicus) are the best known and most common rats, and usually live wherever humans live, especially in less than desirable hygiene conditions. Due to the little information of the 2 hymenolepidid species in brown rats in China, the aim of this study was to understand the prevalence and genetic characterization of H. nana and H. diminuta in brown rats in Heilongjiang Province, China. Total 114 fecal samples were collected from brown rats in Heilongjiang Province. All the samples were subjected to morphological examinations by microscopy and genetic analysis by PCR amplification of the mitochondrial cytochrome c oxidase subunit 1 (COX1) gene and the internal transcribed spacer 2 (ITS2) region of the nuclear ribosomal RNA gene. In total, 6.1% (7/114) and 14.9% (17/114) of samples were positive for H. nana and H. diminuta, respectively. Among them, 7 and 3 H. nana isolates were successfully amplified and sequenced at the COX1 and ITS2 loci, respectively. No nucleotide variations were found among H. nana isolates at either of the 2 loci. Seventeen H. diminuta isolates produced 2 different COX1 sequences while 7 ITS2 sequences obtained were identical to each other. The present results of H. nana and H. diminuta infections in brown rats implied the risk of zoonotic transmission of hymenolepiasis in China. These molecular data will be helpful to deeply study intra-specific variations within Hymenolepis cestodes in the future.

Objective: To explore the antagonistic effect of quercetin on fine particulate matter (PM2.5)-induced embryonic developmental toxicity in vitro.Methods: PM2.5 was collected on glass fiber filters by PM2.5 samplers during the heating period of Dec.2015 to Mar.2016 in an area of Haidian District, Beijing City.The sampled filters were cut into 1 cm×3 cm pieces followed by sonication.The PM2.5 suspension was filtered into a 10 cm glass dish through 8 layers of sterile carbasus and stored at-80 ℃ until freeze drying.Frozen PM2.5 suspension was dried by vacuum freeze-drying.In vitro post-implantation whole embryo culture was used in this study.Pregnant rats with 9.5 gestation days (GD) were killed by cervical dislocation and the uteri were removed into sterile Hank's solution.The embryos with intact yolk sacs and ecto placental cones were induced by PM2.5, and then subjected to intervention of quercetin at the doses of 0.1 μmol/L, 0.5 μmol/L, 1.0 μmol/L and 5.0 μmol/L, respectively.At the end of the 48 h culture period, the cultures were terminated, and all embryos were removed from the culture bottles and placed in prewarmed Hank's solution for evaluation.Morphological evaluation of the embryos was conducted under a stereomicroscope using the morphologic scoring system by Brown and Fabro.The mitochondrial reactive oxygen species (ROS) level was detected by FACSCalibur flow cyto-metry using MitoSOXTM Red staining.Results: An obvious antagonistic effect was achieved through querce-tin at the dose of 1.0 μmol/L, which could result in an increase of visceral yolk sac (VYS) diameter, crown-rump length and head length, somite number, and the differentiation of visceral yolk sac vascular vessels.The scores of allantois, flexion, heart, hind brain, midbrain, forebrain, auditory system, visual system, olfactory system, branchialarch, maxillary process, forelimb bud and hindlimb bud also revealed a significant increase and the relative mitochondrial ROS level of embryonic cells was significantly decreased when compared with PM2.5 group.Although quercetin at the doses of 0.1 μmol/L, 0.5 μmol/L, 5.0 μmol/L also exhibited protective effects against PM2.5-induced embryonic developmental toxicity, the protective effect was weaker when compared with the dose of 1.0 μmol/L.Conclusion: Quercetin at proper dose may be of great benefit for the development of embryos exposed to PM2.5 in the uterus of the rats.Quercetin provides an effective strategy for the prevention of PM2.5-induced embryonic developmental toxicity.Clearance of mitochondrial ROS may be one of its mechanisms.

Gut microbiota provide enzymes and additional biochemical metabolic pathways for the host, which together with the host genome and the external environment, influence the body function. The composition of gut microbiota in infant is closely related to health in later life. However, it is influenced by many factors, including delivery mode, feeding pattern, prenatal diet, pregnancy psychology and antepartum antibiotic treatment. Vaginal delivery and breastfeeding is beneficial for shaping gut microbiota, while cesarean section and formula feeding would reduce the amount of gut dominant bacteria. In addition, inappropriate diet during pregnancy, prenatal stress and antepartum antibiotic treatment alters bacterial colonization of the gut in infant.

Background and objectivehTe prognosis for patients with lung cancer and brain metastases remains poor, with approximately 6 months of survival, despite active measures atfer treatment. In this study, we determined and ana-lyzed clinical parameters that affect the survival of patients with lung cancer and brain metastases to provide clinical guidance. MethodsLung cancer cases with brain metastases were retrospectively collected during 2002 and 2008 from Shanghai Chest Hospital, Shanghai Jiao Tong University.Kaplan-Meier method andCox regression were performed for univariate and multi-variate analyses, respectively, to explore independent predictors inlfuencing the survival of patients with lung cancer and brain metastases.Results Age, Eastern Cooperative Oncology Group performance status (ECOG PS), metastasis interval, number of metastasis, treatment method, treatment period, symptoms of brain metastases, extracranial metastasis, and brain metastasis order were factors that affect the survival of patients with brain metastases as conifrmed through theKaplan-Meiermethod. Treatment periods and extracranial metastasis were independent survival predictors in patients with lung cancer and brain me-tastasis as indicated byCox proportional hazard model.ConclusionTreatment periods and extracranial metastasis were inde-pendent predictors of survival of patients with lung cancer and brain metastasis. Treatment periods and extracranial metastasis were independent predictors of survival of patients with lung cancer and brain metastasis.

Objective To investigate the clinical and neuroimaging features of Vogt-KoyanagiHarada syndrome ( VKH ).Methods Cerebrospinal fluid ( CSF ), neuroimaging examination, clinical manifestation and pharmacotherapy features were investigated in 5 patients diagnosed as VKH. ResultsAll 5 patients were diagnosed as uveitis in the early stage of disease.All patients suffered “ headache”.Meningeal irritation sign was appeared in 3 cases. The MRI enhanced scan of all 5 cases showed abnormal enhancement of meninges. CSF examination showed increased leukocyte number ((4--196) × 106/L). All patients were alleviatedwith combination therapyof high dose of steroid with cyclophosphamide.ConclusionsVKH is a systemic disease that usually involving the uvea, central nervous system, internal ear and the skin. MRI and CSF examination are valuable for diagnosis. High dose of steroid combined with cyclophosphamide is an effective therapeutic strategy.

High performance liquid chromatography coupled with on-line electrospray tandem mass spectrometry (HPLC/ESI-MS/MS) was used to identify C21 steroidal glycosides in the roots of Cynanchum atratum. The structures of C21 steroidal glycosides were deduced from mass fragments features in positive and negative mode. The constituents of C. atratum were separated and detected. 7 compounds were identified by comparing their ESI-MS/MS data with the reference compounds and 2 compounds were inferred solely by the ESI-MS/MS data. The method is sensitive, and provides good separation and rapid qualitative characterization of C21 steroidal glycosides in the roots of C. atratum.
