目的:探讨对比小儿腹腔镜疝囊高位结扎术与开放疝囊高位结扎术的临床效果。方法:在2018年11月至2019年11月的前瞻性研究中,选择了 80名符合纳入标准的原发性腹股沟疝患儿,在内蒙古民族大学内蒙古医院附属医院进行了腹腔镜手术LS(40)或开放手术OS(40)治疗。所有患者均接受原发性腹股沟疝的手术治疗,不包括绞窄疝、嵌顿疝、不可复位疝、复发疝、双侧疝及既往有下腹手术/放疗史。记录手术时间、术中及术后并发症、住院时间、美容效果及睾丸大小,并比较两组疗效的差异。平均随访3.5个月。数据采用SPSS 20.0统计软件进行分析。测量采用(平均值±标准差)、t检验和卡方检验。差异有统计学意义(P<0.05)。结果:所有入选病例均为单侧疝,其中40例开放手术患者中男性38例(95%),女性2例(5%)。腹腔镜组40例中,男性35例(87.5%),女性5例(12.5%)。LS比OS手术时间快[16.73min对19.23min(P<0.05)]。腹腔镜手术较开放手术恢复快,腹腔镜手术LS住院时间较开放手术短(3.053±0.221 Vs 4.10±0.379天,P<0.05)。并发症发生率相似(P=0.432)。腹腔镜手术LS的舒适性优于传统手术OS。结论:腹腔镜手术较传统开放手术的手术时间短,住院时间和恢复时间相对较短。腹腔镜手术有更好的舒适性舒适性,能够探查并修复对侧未闭鞘状突。

The identification of natural, plant-derived compounds with pesticidal properties is crucial for developing environmentally sustainable alternatives to synthetic pesticides. In this study, four major lignans—dihydroclusin, cubebin, clusin, and yatein—were isolated from the crude extract of Piper cubeba fruit. Phytotoxicity assays revealed herbicidal activity against Agrostis stolonifera, with dihydroclusin and clusin exhibiting the highest efficacy, inhibiting seed germination by 50% and showing IC50 values of 2.9 µM and 45 µM, respectively, against Lemna paucicostata. Additionally, all compounds, except dihydroclusin, demonstrated fungicidal activity against the strawberry anthracnose pathogen Colletotrichum fragariae. Moreover, only dihydroclusin exhibited larvicidal activity against Aedes aegypti, causing 96% mortality of mosquito larvae at the 100-ppm concentration tested. These findings highlight the broad-spectrum bioactivity of Piper cubeba lignans, suggesting their potential as alternative agents of synthetic pesticides for managing agricultural pests.

Doxorubicin is associated with adverse effects on organs like liver. This study was done to find the effects of doxorubicin on liver of wistar albino rats. Sixty healthy wistar albino rats were taken for the study. The rats were randomly divided in to 4 groups (2 experimental groups; group AI and A2, and 2 control groups;group Bland B2 each containing 16 rats). The experimental groups were given a single dose of doxorubicin i.e. 10 mg/kg body weight intraperitoneally and sacrificed after 7 days and 14 days for each group. Rats under control groups were given a single intraperitoneal dose of 2.5 ml/kg body weight normal saline and sacrificed with their respective experimental groups. A significant difference (p 〈 0.001) and (p = 0.005) in final body weight was observed among group A1 experimental and BI control rats, and among group A2 experimental and B2 control rats. As compared to group B2 control, group A2 experimental rats had significantly (p = 0.043) lower liver weight. Diameter ofhepatocyte (p 〈 0.001 for both groups) and nucleus (p=0.004 for group A1 and control BI, and p 〈 0.001 for group A2 and control B2) was significantly higher in experimental rats as compared to their respective controls. Cross-sections of the liver of both control groups had normal architecture. However, there was progressive destruction of liver architecture across the experimental groups. Doxorubicin causes the disruption of normal architecture of liver in rats. Thus care needs to be taken during doxorubicin chemotherapy to minimize effects on river.
