鸟类，特别是濒危鸟类同工酶的分析，长期以来一直受到组织学样品来源上的限制。因为在分析实验中普遍采用血液和各种新鲜组织为分析材料，这常常要损伤或杀死动物，对濒危鸟类的保护是不利的。本文以生长羽毛的羽髓组织为材料，进行了乳酸脱氢酶（ＬＤＨ）同工酶的凝胶电泳分析。所得谱带清晰，重复性好，且对鸟体无伤害，是濒危鸟类同工酶分析的理想方法。

对34例萎缩性胃炎患者进行胃窦G细胞密度(GCD)测定,同时观察了胃泌酸功能,血清胃泌素试餐检查、血清壁细胞抗体(PCA)情况。结果;胃窦胃炎组GCD显著低于对照组,其中胃窦中重度萎缩组GCD又低于胃窦轻度萎缩组,差异十分显著;胃体胃炎组GCD高于胃窦胃炎组,差异有非常显著性意义。两组胃粘膜功能改变不同,提示:GCD测定及泌酸功能、血清胃泌素试餐检查有助于萎缩性胃炎的分型诊断,PCA可作为分型的参考指标。

在脓毒症发生发展期间, 中性粒细胞诱捕网（NETs）的形成及细胞凋亡坏死会导致组蛋白释放至细胞外, 形成细胞外游离组蛋白（CFHs). CFHs从多个方面参与脓毒症的发生发展, CFHs具有一定抗菌效果, 会破坏细胞 膜产生细胞毒性, 参与炎症反应, 损伤内皮细胞, 影响凝血功能, 以此延长脓毒症的病程, 加重病情。CFHs作为脓毒 症潜在治疗靶点也得到了很大的发展, 出现了抑制CFHs的产生, 降低循环中的CFHs的含量或降低CFHs细胞毒性 等治疗方法, 有望成为治疗脓毒症的新策略。 [ABSTRACT FROM AUTHOR]

术后阿片类药物长期使用（PPOU）尚无标准定义，多数研究采用的定义为术后使用阿片类药物超过90 d。 PPOU的不良反应不仅影响患者生活质量，还可能威胁患者生命安全。PPOU可能的危险因素包括术前、术后阿片 类药物的使用，控释制剂和复方制剂的不恰当应用，患者存在焦虑、抑郁，以及出院后患者重复或补充开药等。在多 学科团队合作的基础上实施涵盖术前、术中、术后住院期间乃至出院后各个阶段的综合疼痛管理措施有望减少 PPOU。而近年研究表明，去阿片化镇痛对缓解患者出院后疼痛和减少 PPOU似乎并无明显作用，还可能增加严重 不良反应，其能否在临床推广仍需进一步研究；这也意味着阿片类药物将在围手术期疼痛管理中继续占据重要地 位，PPOU的不利影响将持续存在。 [ABSTRACT FROM AUTHOR]

To investigate the effect of budesonide suspension on Toll like receptor 4 (TLR4) / myeloid differentiation factor 88 (MyD88) / nuclear factor κB in lung tissue of asthmatic mice. 40 cough variant asthma mice models were established by CO sensitizing mice with 4 % ovalbumin and 2 % Al (OH3 ). The model rats were intervened with low, medium and high doses (0.2, 1.0 and 2.0 g/kg) of budesonide suspension and montelukast sodium respectively, once a day for 14 days, and the bronchoalveolar tissues were collected at the time of intervention for 14 days The levels of leukocytes (WBC), eosinophils, IFN-γ, IL-1β and TNF-α in BALF of each group were compared, and the differences in the scores of epithelial hyperplasia, inflammatory cell infiltration and total pathological changes, as well as the expression of TLR4, MyD88 and p65 proteins in lung tissue of each group were analyzed. Budesonide suspension can significantly reduce the number of leukocytes and eosinophils in BALF of asthmatic model mice, and can also improve the airway and bronchial epithelial hyperplasia and inflammatory cell infiltration in lung tissue of mice, and the expression levels of TLR4, MyD88 and p65 protein in lung tissue of mice decreased significantly after intervention. Budesonide suspension can improve the asthma model mice The mechanism of action may be related to the regulation of TLR4, MyD88, p65 protein expression, and then affect the process of inflammation and immune response.

Objective: To investigate the efficacy of triptorelin combined with low-dose growth hormone in the treatment of girls with central precocious puberty (CPP) and its effect on bone age. Methods: A total of 200 girls with CPP, who were admitted to People's Hospital of Shaanxi Province from January 2017 to January 2020, were chosen as research subjects and were randomly divided into control group (n=100) and study group (n=100).The control group was given conventional treatment, and the study group was given triptorelin combined with low-dose growth hormone therapy. The clinical efficacy of, serum sex hormone levels before and after treatment, changes in uterine volume, ovarian volume, and changes in growth and development indicators of the two groups of patients were observed. Results: After treatment, the total effective rate (98 %) in the study group was significantly higher than that (80 %) in the control group (P<0.05). The levels of FSH, LH, E2, uterine volume, and ovarian volume of the two groups were reduced, and bone age, height, and PAH were significantly increased. The above indicators of the study group were significantly better than those of the control group (P<0.05). Conclusion: Triptorelin combined with low-dose growth hormone has a significant effect in the treatment of girls with CPP. It can improve the serum sex hormone levels, uterine volume, and ovarian volume of the girls with CPP . It has positive significance for growth and development indicators and is worthy of clinical promotion and application. [ABSTRACT FROM AUTHOR]

Objective To observe the drug resistance of human epithelial ovarian cancer cell line SKOV3/DDP added with reversal dose of mifepristone (MIF). Methods The proliferation inh伽tion rate ofM IF on SKOV3 and SKOV3/ DDP cell in logarithmic growth phase were detected byM TT method, and we selected the noncytotoxic dose ofM IF as reversal dose. The resistance index (RI) of SKOV3/DDP cells to cisplatin (DDP) was further measured by MTT. SKOV3/ DDP cells were distributed into the group A and group B. C ells in the group A were added with DDP, group B with DDP and 5 μmoVLM IF. The IC 50 of SKOV3/DDP cells was measured byM TT at 24, 48, and 72 h, respectively, and then we calculated the reversal fold (RF). The cell cycle of SKOV3/DDP was detected by flow cytometry (FCM). Results MTT assay results showed that mifepristone inhibited the proliferation of SKOV3 and SKOV3/DDP cells in a dose-dependent manner. The reversal dose ofM IF on SKOV3/DDP was 5 μmoVL. The IC50 of SKOV3 and SKOV3/DDP to DDP were 3. 22 and 14. 83 μg/ml, respectively, and the RI of SKOV3/DDP to DDP was 4. 61. The IC50 of group A was (23. 13 土 0. 83), (14. 83 土0.52), (10. 07 土0.56) μg/mL at 24, 48 and 72 h after culture, and (17. 06 土0.53), (7.77 土 0.47) and (4.06 土 0.69) μg/mL in the group B, respectively, and the RF ofM IF to SKOV3/DDP were 1. 36, 1. 91, and 2. 48, respectively. After 24, 48, and 72 hours of culture, the proportion of SKOV3/DDP cells added with 5 μmol/L MIF in the G0/G1 phase increased gradually (48. 7%, 53. 9%, 55. 1 %, and 59. 0%), while the proportion of cells in the S phase decreased gradually (13. 5%, 9. 6%, 7. 7%, and 5. 8%). C onclusion MIF (5 μmol/L) could inhibit the proliferation of SKOV3/DDP cells and reduce the resistance of SKOV3/DDP cells to DDP, and the possible mechanism might be that MIF can block the cell cycle of SKOV3/DDP in the G0/G¹ phase [ABSTRACT FROM AUTHOR]

[Objective] The present paper aimed to clarify the flower-visiting insect species and visiting rule of dominant species in parsley, provide theoretical basis for the selection of nectar plant species. [Method] The insect species of parsley were investigated and identified, and the rhythm of dominant species was studied. [Result] There were 38 species of parsley flower-visiting insects, belonging to 19 families of 6 orders, among which Diptera, Hymenoptera and Coleoptera were the main species, and predacious hoverfly were the dominant species of parsley. Hoverflies began their activities on parsley flowers at 9:00 in the morning until 18:00 and 11 :00 -16 :00 was the peak activity period. [Conclusion] There are many natural enemies in the flower visiting insects of parsley, and parsley is a good nectar plant. [ABSTRACT FROM AUTHOR]
