Objective To study the effects of the compound xueshuantong capsule ( FXC) against cerebral ischemia and hypoxia in mice. Methods KM mice were randomly divided into the sham operation group ( normal control group) , model control group, positive control group and FXC at high-,medium-and low-dose(0. 75,1. 50,and 2. 25 g·kg-1 ) groups. After intragastric administration for 7consecutive days,cerebral ischemia model was established by unilateral carotid arteries ligation. The cerebral water content and stroke index were recorded. The viability of the mice was determined by testing atmospheric hypoxia,sodium nitrite poisoning and acute cerebral anoxia. Results FXC decreased water content and stroke index of the mice suffered from unilateral carotid artery ligation dose-dependently (P<0. 05,P<0. 01) . It also prolonged the survival of mice by tolerating absence of oxygen,sodium nitrite poisoning and acute cerebral anoxia (P<0. 05,P<0. 01). Conclusion FXC has a protective effect on cerebral ischemia and hypoxia in mice.

BACKGROUND:Studiesin vitro have suggested that icarin can attenuate lipopolysaccharide (LPS)-induced acute pneumonia. Is the anti-inflammatory effect of icarin stil valid in the presence of wear particles? OBJECTIVE:With studiesin vivo andin vitro, to investigate the regulatory effect of icarrin on titanium particle-induced inflammatory reaction. METHODS:(1) Studiesin vivo: Eighty male C57BL/6 mice aged 6-8 weeks were randomly divided into four groups: control group, icarin group, titanium particle group, and titanium particle+icarin group. Mice in the titanium particle group and titanium particle+icarin group received surgical procedure, and sterile and endotoxin-free titanium particles were implanted on the calvaria surfaces to induce inflammatory reaction. Mice in the control group and icarin group received the same surgery, but no wear particles were implanted. Then icarin was given oraly to mice in the titanium particle group and titanium particle+ icarin group with a dose of 200 mg/kg per day for 2 weeks from the day of modeling. Mice in the control group and icarin group were given oraly the same dose of placebo. Two weeks later, tumor necrosis factor-α and interleukin-1β at protein and mRNA levels were respectively detected with enzyme-linked immunohistochemical (ELISA) and quantitative real time reverse transcription PCR (qRT-PCR) analysis. (2) Studiesin vitro: Mouse monocyte/macrophage RAW264.7 cels were cultured with different conditioned media: control group, nuclear factor receptor ligand кB (RANKL); icarin group, RANKL+icarin; titanium particle group, RANKL+titanium particles; titanium particle+icarrin group, RANKL+icarin+titanium particles. Titanium particles stimulated RAW264.7 cels were co-cultured with RANKL and icarin for 72 hours. Tumor necrosis factor-α and interleukin-1β at protein and mRNA levels in the supernatant were detected with ELISA analysis and qRT-PCR, respectively. RESULTS AND CONCLUSION: (1) Resultsin vivo: icarin treatment obviously decreased titanium particle-induced inflammatory cellinfiltration and made the thickness of periosteum thinner, down-regulated tumor necrosis factor-α and interleukin-1β expressions at protein and mRNA levels. (2) Results in vitro: when RAW264.7 cels were stimulated with titanium particles for 72 hours, tumor necrosis factor-α and interleukin-1β expressions at protein and mRNA levels in culture media increased obviously; when icarin was administrated, tumor necrosis factor-α and interleukin-1βexpressions at protein and mRNA levels down-regulated significantly. These results suggest icarin can obviously suppress titanium particle-induced inflammatory reactionin vivo andin vitro.

OBJECTIVETo identify the genetic alterations in nonsyndromic cleft lip and palate (NSCLP).

METHODSComparative genomic hybridization was applied to investigate the genomic imbalance (the gain or loss of genetic material) in 7 cases of NSCLP.

RESULTSIt showed that the loss of chromosome DNA copies happened in chromosome 6, 7, 10, 13, 14, 16, 20, 22 and the gain of chromosome DNA copies happened in chromosome 5, 15, 18, 19. Conclusions 13q had a high frequency (71.4%) of chromosome loss.

CONCLUSIONSAbnormal chromosome DNA copies happen in all the patients with NSCLP. Most of the patients have chromosome DNA copies loss. It suggests that loss of inhibitory gene may be related to the NSCLP. The related inhibitory gene may locate in 13q.

Objective: Para-aortic lymph node dissection (PALND) is a widely used treatment that causes many complications. This study is to evaluate the efficacy and safety of nerve-sparing para-aortic lymph node dissection (NSPALND) by comparing it with conventional PALND in gynecological malignancies and to prove whether locating the superior hypogastric plexus (SHP) can help reveal the para-aortic nerves. Methods: This is a retrospective study of the patients who underwent para-aortic lymphadenectomy from January 2020 to December 2022 at Zhejiang Cancer Hospital. All of them were divided into NSPALND and PALND groups according to whether or not nervesparing was performed. The surgical, functional and oncological outcomes were evaluated. Results: There were 43 patients enrolled, of which, 20 patients underwent NSPALND and 23 patients underwent PALND. The para-aortic nerves were successfully revealed by locating the SHP in all 20 cases of NSPALND. The post-operative anal exhaust time in the NSPALND group was significantly shorter than that in the PALND group (2.5 vs. 4 days, p=0.006), and the incidence of acute intestinal obstruction in the NSPALND group was significantly lower than that in the PALND group (10% vs. 39%, p=0.029). There was no difference between the two groups in terms of catheterization duration, urinary retention, dysuria, as well as the number of lymph nodes removed and the para-aortic recurrence rate. Conclusion NSPALND can significantly reduce the rate of acute intestinal obstruction and improve post-operative intestinal function. Locating the SHP and using it as an anatomical landmark to reveal the para-aortic nerves is feasible. Its exact clinical value needs to be further studied.

Objective To investigate whether the left ventricular delayed contraction site determined by tissue Doppler imaging might be an optimal left ventricular lead position for improved outcomes of cardiac resynchronization therapy (CRT) in patients with non-ischemic cardiomyopathy. Methods Thirty-three patients subjected to CRT were selected, and all were performed conventional ultrasound cardiography and tissue Doppler examinations before operation. The left ventricular delayed contraction site was determined according to the interval between the onset of QRS and the peak systolic velocity. Retrograde coronary venography was performed during operation, and the left ventricular lead site was selected according to the left ventricular delayed contraction site determined by tissue Doppler examination before operation. The coronary sinus lead site was determined under the guidance of X ray of dorsaventral, lateral, right anterior oblique and left anterior oblique positions. Patients were divided into group A(n=20, the left ventricular lead site was in line with the delayed contraction site) and group B (n=13, the left ventricular lead site was not in line with the delayed contraction site). Results There was no significant difference in age, NYHA grading, left ventricular end-systolic volume(LVESV), left ventricular ejection fraction(LVEF), pulmonary arterial systolic pressure, QRS width and Ts-SD between the two groups before operation(P> 0.05). Six months after CRT, there was no significant difference in NYHA grading, LVESV and mitral regurgitation(MR) grading between the two groups(P>0.05), while the increase in LVEF and decrease in LVESV of group A were more significant than those of group B (P<0.01). Conclusion In patients with non-ischemic cardiomyopathy, CRT significantly improves left ventricular performance, and the more favourable outcomes are achieved in those pace at the delayed contraction site. Tissue Doppler imaging may help to guide the implant of left ventricular lead.
