Effects of non-endotracheal intubation versus endotracheal intubation in thoracic surgery / 中国胸心血管外科临床杂志

@#Objective    To investigate the feasibility and safety of non-intubation anesthesia in thoracic surgery. Methods    From September 2017 to December 2019, 296 patients were operated at department of thoracic surgery in our hospital. There were 167 males and 129 females with an average age of 50.69±12.95 years, ranging from 16 to 76 years. The patients were divided into two groups according to whether they were intubated: 150 patients were in a non-intubation group, including 83 males and 67 females with an average age of 49.91±13.59 years, ranging from 16 to 76 years, and 146 patients were in an intubation group including 84 males and 62 females with an average age of 51.49±12.26 years, ranging from 16 to 74 years. Intraoperative data, postoperative recovery, inflammatory response of the two groups were compared. Results    There was no statistical difference between the two groups in operation time, blood loss, the lowest oxygen saturation or other indicators (P>0.05). But the highest partial pressure of carbon dioxide of the non-intubation group was higher than that of the intubation group (P=0.012). The non-intubation group was superior to the intubation group in postoperative recovery and inflammatory response (P<0.05). Conclusion    The non-intubation anesthesia is safe and maneuverable in thoracic surgery, and it has some advantages in accelerating postoperative rehabilitation.

Progress of synergistic factors of histone lysine specific demethylase 1 in colorectal cancer / 肿瘤研究与临床

The expression of histone lysine-specific demethylase 1 (LSD1) in colorectal cancer cells is increased, and LSD1 is closely related to its occurrence, development, proliferation, invasion and metastasis. LSD1 is a demethylase whose function depends on flavin adenine dinucleoside. It can specifically catalyze the demethylation reaction of histone lysine, and regulate the expression of target genes by reaction of demethyl and dimethyl (H3K4me, H3K4me2, H3K9me, and H3K9me2) at the 4th and 9th positions of lysine H3. Targeted inhibition of LSD1 has been proved to be able to exert significant anti-tumor effect, but since the tumors involve multiple centers and factors, later studies have found that single inhibition of LSD1 cannot completely and effectively kill tumor cells. Moreover, the specificity of the LSD1 catalytic substrate depends to a large extent on the synergistic factors that bind to it and form complexes. The double-target inhibitors based on LSD1 shows more remarkable effect in tumor inhibition. Therefore, finding the combined synergistic factors of LSD1 may provide the basis for the research of multi-target inhibitors.

A clinical research of Lingshao-Zaoren granule for the female with overactive bladder symptom: a randomized, double-blind, placebo-controlled trial / 国际中医中药杂志

Objective To evaluate the effectiveness of Lingshao-Zaoren granule in the treatment of female overactive bladder. Methods A total of 60 female OAB patients who met the inclusion criteria were randomly divided into 2 groups, 30 cases in each group. The control group recieved the Tolterodine Tartrate Sustained Release Tablets and the Lingshao-Zaoren granule placebo, and the treatment group used the Tolterodine Tartrate Sustained Release Tablets and the true Lingshao-Zaoren granule treatment. Both groups were treated for 4 weeks. Overactive bladder symptom scale (OABSS) was used to determine the severity of OAB.Results After treatment 14,28 d,OABSS scores of the treatment group(5.3 ± 2.3,1.4 ± 1.2 vs.8.4 ± 2.4,F=137.209),and control group(7.8 ± 1.9,6.8 ± 1.4 vs.8.6 ± 2.6,F=8.927),were significantly lower than the baseline of each group respectively (P<0.01). Besides, OABSS scores of the treatment group after 14 and 28 d were significantly lower than the control group (t=4.668, 15.678, P<0.01). The pain scores (5.9 ± 1.9, 2.7 ± 1.1 vs.9.5 ±2.3,F=108.819)of treatment group at 14 and 28 d were significantly lower than the baseline(P<0.01);and the pain scores of treatment group at 14 and 28 d were significantly lower than the control group (t=6.342, 14.812,P<0.01).The lower abdomen discomfort scores at 14,28 d in treatment group(1.9 ± 1.4,1.1 ± 1.0 vs. 3.3 ±1.1,F=28.762),and control group(2.7 ±1.0,2.4 ±0.8 vs.3.4 ±1.2,F=12.103)were significantly lower than the baseline of each group (P<0.01); and the abdominal discomfort scores of treatment group at 14, 28 d were significantly lower than the control group (t=2.521, 5.041, P<0.05 or P<0.01). Conclusions The Lingshao-Zaoren granule could decrease OABSS score,pain score,abdominal discomfort symptoms,improve clinical symptoms of the female patients with OAB.
