This paper reports the effects of common marine medicinal animals and their clinical applications in gynecological diseases for the fist time in Nanji Archipelago National Marine Nature Reserve of Zhejiang Province. The results show that pharmacological effects of 93 species, which belong to 5 phyla, of marine medicinal animals are obvious in clinical applications of gynecological diseases. According to pharmacological effects, marine medicinal animals in clinical applications can be divided into twelve groups: 1. drugs for leukorrha-gia; 2. drugs for anemia and uterine bleeding; 3. drugs for intermenstrual flow or metror-rhagia; 4. oxytocic drug; 5. lactogenic drugs,- 6. drugs for menoxenia; 7. drugs for pregnancy hypertension; 8. drugs for postpartum hemorrhage; 9. drugs for postpartum constipation; 10. drugs for mastitis; 11. drugs for amenorrhoea; 12. emmenagogue;

OBJECTIVETo explore the linkage relationship between specific genetic markers and arrhythmogenic right ventricular cardiomyopathy (ARVC) in Chinese pedigrees.

METHODSThe microsatellite genetic markers D2S152, D14S252, and D10S1664 were studied for their linkages to ARVC in five Chinese ARVC pedigrees and a normal population of 121 Chinese individuals. Genomic DNA of the pedigrees and normal population was amplified using PCR techniques. Denaturing polyacrylamide sequencing gel (4%) electrophoresis was used to detect microsatellite repeat polymorphisms. Gels were silver-stained. A classical linkage analysis program was used assuming models of autosomal dominance and recession.

RESULTSThe logarithm of the odds (LOD) scores of D2S152 with ARVC in LW, WD, DS, LC and TY pedigrees were 2.174, -0.589, -infinity, - (indicating that linkage is not supported in this mode), and -infinity respectively in autosomal dominant model (recombination fraction = 0.000 respectively)and were -infinity, -infinity, -infinity, -infinity, and 0.182 respectively in the autosomal recessive model. The LOD scores of D14S252 with ARVC in LW, WD, DS, LC and TY pedigrees were -, -, -infinity, -, and 0 respectively in autosomal dominant model, and were -infinity, -0.812, -infinity, -infinity, and 0.087 respectively in autosomal recessive model. The LOD scores of D2S152 with ARVC in LW, WD, DS, LC and TY pedigrees were -, -0.539, -, and 0.602 respectively in autosomal dominant model and were -, -infinity, -infinity, -infinity, and - infinity respectively in autosomal recessive model.

CONCLUSIONSThe LOD score for D2S152 in the LW pedigree was 2.174, indicating that the chance of linkage is about 150:1. This suggests that there is a possible ARVC-related gene near this marker. There were no clear linkage relationships between ARVC and D10S1664 and D14S252 in this family, and no linkages between ARVC and any of the three genetic markers in the other four families. These results also suggest that there is genetic heterogeneity in LW and in the other pedigrees.

【Objective】 To analyze the sensory integration characteristics of 4- to 5-year-old preschool children while maintaining static balance, in order to provide reference for promoting the development of motor development. 【Methods】 A total of 128 preschool children were randomly selected in this study from a public kindergarten in Suzhou. Wearable sensor were worn at the center of mass(COM) position for four tests: T1 standing with eyes open, T2 standing with eyes closed, T3 standing with eyes open on a sponge pad, and T4 standing with eyes closed on a sponge pad. The angular velocity modulus(ω) of COM shaking was extracted, the Romberg quotient(RQ), vestibular Romberg quotient(VRQ), and the rate of increase in body stability when integrating different sensations were calculated. The contribution weights and sensory integration characteristics of visual, proprioceptive, and vestibular sensations to static balance were analyzed. Independent sample t-test was used to analyze the differences between different gender and age groups. 【Results】 The RQ was 1.20, and the VRQ was 1.58. The contribution rates of visual, proprioceptive, and vestibular senses to body balance were approximately 9.28%, 28.19% and 62.53%, respectively. The difference in the rate of increase in body stability between integrated vision and integrated proprioception with normal vestibular perception was statistically significant(P<0.001, Cohen′s d=-1.14),while the difference in the rate of increase in body stability between integrated proprioception and vestibular perception with normal vestibular perception and integrated vision with normal proprioception was statistically significant(P<0.001, Cohen′s d=2.30). The difference in the rate of increased body stability between the sum of vestibular and proprioceptive integration and the simultaneous integration of visual and proprioceptive integration was statistically significant(P<0.001, Cohen′s d=-0.86). The gender differences in RQ, VRQ, and the rate of increased body stability when integrating different sensations(P>0.05) and the difference in half year old age was not statistically significant(P>0.05). 【Conclusions】 When preschool children aged 4 - 5 maintain static balance, the contribution of vestibular integration proprioception to body stability is greater than that of vestibular integrate vision. The contribution of vestibular and visual integrate proprioception to body stability is greater than that of vestibular and proprioception integrate vision. The sensory integration characteristics between boys and girls, as well as half year old children, are basically the same.

Bacterial antitumor therapy has great application potential given its unique characteristics, including genetic manipulation, tumor targeting specificity and immune system modulation. However, the nonnegligible side effects and limited efficacy of clinical treatment limit their biomedical applications. Engineered bacteria for therapeutic applications ideally need to avoid their accumulation in normal organs and possess potent antitumor activity. Here, we show that macrophage-mediated tumor-targeted delivery of Salmonella typhimurium VNP20009 can effectively reduce the toxicity caused by administrating VNP20009 alone in a melanoma mouse model. This benefits from tumor-induced chemotaxis for macrophages combined with their slow release of loaded strains. Inspired by changes in the tumor microenvironment, including a decrease in intratumoral dysfunctional CD8⁺ T cells and an increase in PDL1 on the tumor cell surface, macrophages were loaded with the engineered strain VNP-PD1nb, which can express and secrete anti-PD1 nanoantibodies after they are released from macrophages. This novel triple-combined immunotherapy significantly inhibited melanoma tumors by reactivating the tumor microenvironment by increasing immune cell infiltration, inhibiting tumor cell proliferation, remodeling TAMs to an M1-like phenotype and prominently activating CD8⁺ T cells. These data suggest that novel combination immunotherapy is expected to be a breakthrough relative to single immunotherapy.

Owing to the increasing incidence and prevalence of inflammatory bowel disease (IBD) worldwide, effective and safe treatments for IBD are urgently needed. Hydrogen sulfide (H₂S) is an endogenous gasotransmitter and plays an important role in inflammation. To date, H₂S-releasing agents are viewed as potential anti-inflammatory drugs. The slow-releasing H₂S donor 5-(4-hydroxyphenyl)-3H-1,2-dithiole-3-thione (ADT-OH), known as a potent therapeutic with chemopreventive and cytoprotective properties, has received attention recently. Here, we reported its anti-inflammatory effects on dextran sodium sulfate (DSS)-induced acute (7 days) and chronic (30 days) colitis. We found that ADT-OH effectively reduced the DSS-colitis clinical score and reversed the inflammation-induced shortening of colon length. Moreover, ADT-OH reduced intestinal inflammation by suppressing the nuclear factor kappa-B pathway. In vivo and in vitro results showed that ADT-OH decreased intestinal permeability by increasing the expression of zonula occludens-1 and occludin and blocking increases in myosin II regulatory light chain phosphorylation and epithelial myosin light chain kinase protein expression levels. In addition, ADT-OH restored intestinal microbiota dysbiosis characterized by the significantly increased abundance of Muribaculaceae and Alistipes and markedly decreased abundance of Helicobacter, Mucispirillum, Parasutterella, and Desulfovibrio. Transplanting ADT-OH-modulated microbiota can alleviate DSS-induced colitis and negatively regulate the expression of local and systemic proinflammatory cytokines. Collectively, ADT-OH is safe without any short-term (5 days) or long-term (30 days) toxicological adverse effects and can be used as an alternative therapeutic agent for IBD treatment.
