This study aims to explore the mechanism of Yanghe Decoction(YHD) against subcutaneous tumor in pulmonary metastasis from breast cancer, which is expected to lay a basis for the treatment of breast carcinoma with YHD. The chemical components of medicinals in YHD, and the targets of the components were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and SwissTargetPrediction. The disease-related targets were searched from GeneCards and Online Mendelian Inheritance in Man(OMIM). Excel was employed to screen the common targets and plot the Venn diagram. The protein-protein interaction network was constructed. R language was used for Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment. A total of 53 female SPF Bablc/6 mice were randomized into normal group(same volume of normal saline, ig), model group(same volume of normal saline, ig), and low-dose and high-dose YHD groups(YHD, ig, 30 days), with 8 mice in normal group and 15 mice in each of the other groups. Body weight and tumor size was measured every day. Curves for body weight variation and growth of tumor in situ were plotted. In the end, the subcutaneous tumor sample was collected and observed based on hematoxylin and eosin(HE) staining. The mRNA and protein levels of hypoxia inducible factor-1α(HIF-1α), pyruvate kinase M2(PKM2), lactate dehydrogenase A(LDHA), and glucose transporter type 1(GLUT1) were detected by PCR and Western blot. A total of 213 active components of YHD and 185 targets against the disease were screened out. The hypothesis that YHD may regulate glycolysis through HIF-1α signaling pathway to intervene in breast cancer was proposed. Animal experiment confirmed that the mRNA and protein levels of HIF-1α, PKM2, LDHA, and GLUT1 in the high-and low-dose YHD groups were lower than those in the model group. YHD has certain inhibitory effect on subcutaneous tumor in pulmonary metastasis from breast cancer in the early stage, which may intervene pulmonary metastasis from breast cancer by regulating glycolysis through HIF-1α signaling pathway.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective: To investigate the safety and feasibility of pure single-port laparoscopic distal gastrectomy (SDG) in the radical treatment of gastric cancer. Methods: A retrospective cohort study with propensity score matching (PSM) was conducted. Subjects were included in the study who were diagnosed by imaging examination and pathology as early distal gastric cancer, no distant metastasis, no serious cardiovascular and cerebrovascular diseases and underwent radical gastrectomy. Patients with incomplete clinical data, unplanned second operation and complicated with other tumors were excluded. A retrospective analysis was performed on 15 patients who underwent pure SDG radical gastrectomy for gastric cancer from September 2020 to March 2022, namely the SDG group. Fifty-eight patients undergoing conventional five-port laparoscopic radical gastrectomy for gastric cancer were included as the control group, namely the LDG group. As it was found that there was a statistically significant difference in baseline body mass index (BMI) between the two groups [(20.8±0.8) kg/m² vs. (22.9±0.4) kg/m², t=2.456, P=0.017], one-to-one PSM was conducted between the two groups. Then the basic conditions of the two groups of patients in perioperative period were analyzed and compared. Results: There were 14 patients after PSM in the SDG group and the LDG group respectively. There were no significant differences in intraoperative bleeding, number of lymph nodes dissected, time to the first postoperative feeding and postoperative complications between the SDG group and the LDG group (all P>0.05). Compared with LDG group, the operative time in the SDG group was longer [(163.6±6.3) minutes vs. (133.9±4.4) minutes, t=3.866, P=0.001]. However, in the SDG group, time to the first flatus [(2.6±0.2) days vs. (3.3±0.1) days, t=3.053,P=0.005], time to drainage tube removal [(4.5±0.8) days vs. (6.9±0.2) days, t=2.914, P=0.007)] and postoperative hospital stay [(6.7±0.1) days vs. (9.2±1.0) days, t=2.534,P=0.018)] were significantly shorter, and pain score at the first postoperative day evaluated by NRS (1.86±0.29 vs. 2.86±0.35, t=2.205, P=0.037) was significantly lower as compared to the LDG group. Four patients in SDG group did not receive peritoneal drainage tube placement after surgery, and they all recovered safely. Conclusion: The pure single-port laparoscopic radical gastrectomy for gastric cancer is safe and feasible, and has an advantage over the LDG in postoperative recovery.

OBJECTIVE: To investigate the related factors influencing plasma transfusion efficacy so as to improve the plasma transfusion efficiency. METHODS: According to the clinical symptoms and the laboratorial results, the patients were divided into transfusion efficient and inefficient groups. A total of13090.8 units of plasma were transfused to 4423 patients. The clinical symptoms and the hemorrhage related index per- and pro-transfusion, plasma components sorts, storage time, and the dose of plasma (kg/ml) transfusion were analyzed. RESULTS: The largest transfusion volume of plasma were in intensive care unit (ICU) accounted for 30.36%, the largest blood plasma per patient transfusion was in cardiac surgery (3.96 U). The analysis of transfusion efficiency showed that in terms of patient age, there were difference in transfusion efficiency among the patients with different ages (P＜0.001). The effective transfusion rate in the group of age ＜18 was 53%, which was higher than that in group of age 18-60(41%) and group of age ＞60 (30%); in terms of sex, the effective transfusion rate in female group was higher than that in male group (42% vs 37%) (P＜0.001); in terms of transfusion plasma volume/body weight, there were differences in transfusion efficiency (P＞0.05). The multi-factor logistic regression analysis showed that there was no significant correlation among the plasma sorts, storage time of the plasma pre-transfusion and transfusion efficiency(P＞0.05). The analysis of the non-hemolytic fever reaction caused by plasma transfusion revealed that there was no statistical difference between the plasma and the leukocyte-depleted plasma groups (P＞0.05). CONCLUSION The plasma transfusion effectiveness relates with age and sex, but not relates with the transfusion plasma voume/body weight, plasma sorts, and the duration of storage.

Objective:To study the efficacy of integrative medicine on congenital muscular torticollis. Methods:From October, 2017 to September, 2019, 80 children with congenital muscular torticollis were divided into group 1 (n = 40) and group 2 (n = 40) according to different treatment schemes. Group 1 received comprehensive physiotherapy, including passive stretching, head control training, posture correction and family rehabilitation. Group 2 received Tuina in addition. Before and six months after treatment, the root mean square (RMS) of surface electromyography of bilateral sternocleidomastoid muscles in supine neutral position, neck rotation and stretch, and the range of motion of passive neck rotation and lateral flexion, and the angle of head deviation from the midline to the affected side were compared. Results:Before treatment, the RMS of sternocleidomastoid muscle in each position was lower in the affected side than in the healthy side (P < 0.01), and the range of motion of neck when lateral flexion to the healthy side and rotation to the affected side was less than that of the other side (P < 0.01) in both groups; however, no significant difference was found between two groups (P > 0.05). After treatment, the RMS of EMG of sternocleidomastoid muscle in each position, and the range of motion of neck when lateral flexion to the healthy side and rotation to the affected side improved (|t| > 3.290, P < 0.01) in both groups, and were better in group 2 than in group 1 (t > 2.401, P < 0.05); the angle of head deviation from the midline to the affected side significantly decreaed (t > 15.075, P < 0.001) in both groups, and was significantly less in group 2 than in group 1 (t = -4.971, P < 0.001). Conclusion:Integrative medicine is effective on infant with congenital muscular torticollis, which is superior to comprehensive physiotherapy only.
