Objective To compare the effect of different sevoflurane induction methods on hemodynamics and immune function in elderly patients with tumor. Methods One hundred and sixty elderly patients with tumor underwent general anesthesia were enrolled, the patients were divided into observation group and control group according to the anesthesia method with 80 cases each. The observation group was received induction method of initial concentration of 2%sevoflurane and increased by 1% per 3 times breathing and then to a final concentration of 4%- 5%. The control group was received 5% sevoflurane induction concentration. The anesthesia induction time, intubation time, recovery time and untoward reaction were recorded. The changes of heart rate, mean arterial pressure (MAP), oxygen saturation of pulse (SpO2), bispectral index (BIS) and CD3+, CD4+, CD8+, CD4+/CD8+were observed. Results There were no statistical differences in BIS, heart rate, SpO2, CD3 +, CD8 + and incidence of untoward reaction between 2 groups (P>0.05). The MAP at immediate intubation in observation group was significantly higher than that in control group:(69.38 ± 10.42) mmHg (1 mmHg=0.133 kPa) vs. (58.52 ± 6.12) mmHg, but the MAP at after intubation was significantly lower than that in control group: (77.12 ± 11.31) mmHg vs. (90.13 ± 9.24) mmHg, there were statistical differences (P<0.05). The anesthesia induction time and intubation time in observation group were significantly longer than those in control group:(110.1 ± 14.2) s vs. (101.4 ± 15.8) s and (341.2 ± 57.3) s vs. (310.4 ± 60.8) s, but the recovery time was significantly shorter than that in control group: (271.2 ± 31.3) s vs. (321.8 ± 41.5) s, there were statistical differences (P<0.05). The CD4+and CD4+/CD8+at end of surgery and 1 d after surgery in observation group were significantly higher than those in control group, CD4+:0.241 ± 0.027 vs. 0.182 ± 0.034 and 0.332 ± 0.039 vs. 0.284 ± 0.042, CD4+/CD8+: 0.84 ± 0.12 vs. 0.69 ± 0.13 and 1.09 ± 0.52 vs. 0.93 ± 0.43, there were statistical differences (P<0.05). Conclusions Induction method of gradually increasing concentration of sevoflurane enables the hemodynamics of elderly tumor patients more stable. In addition, this method can reduce the inhibitory effect on T lymphocytes to some extent.

Laboratory animal industry forms an independent, comprehensive system responsible for the production, use and management of laboratory animals.Great advances have been made in this field in China over the more than thirty years of development.However, due to the great development and changes during this long time, there are also some issues which need to be amended and changed.To compare the concepts of experimental animals in China and developed countries such as USA.The key concepts on the laboratory animals are not well or clearly defined in the regulatory documents in China, which hinder the healthy development and effective regulation in this field, as well as the care and use of laboratory animals in research and education.In this article, we discuss the necessity of timely amendment and standardization of the key concepts and definitions related to laboratory animals, and the importance and impact of the key concepts on the development of animal industry in China.

Improving the quality of newborns is a health development strategy, which has attracted global attention. Adverse pregnancy outcomes, including preterm birth, low birth weight and small for gestational age, are major causes of perinatal mortality and disability. Based on review of international and national publications pertaining to associations between stressful life events during pregnancy and adverse pregnancy outcomes from 2007 to 2023, this review summarizes the correlation between stressful life events during pregnancy and adverse pregnancy outcomes, including preterm birth, low birth weight and small for gestational age, and describes the underlying biological mechanisms. Previous studies have demonstrated the associations between maternal stressful life events during pregnancy and adverse pregnancy outcomes, and the underlying mechanisms mainly include neuroendocrine regulation, inflammation and microbiota pathways; however, the exact mechanisms remain unclear until now. Further studies to identify the critical window period for the association between stressful life events and adverse pregnancy outcomes, and unravel the pathogenesis of adverse pregnancy outcomes are warranted, so as to provide insights into reduction of adverse pregnancy outcomes.

Objective To Study the effect of long-term triptolide use on the content of the normal rat plasma ACTH.Methods 20 male SD rats were divided into 2 groups randomly,and gavaged for 7 weeks.The control group was 10 with 2%propylene glycol 2ml/kg,bid;the group of Triptolide was 10 with 2% the mixture of propylene glycol and Triptolide 20?g/kg,bid.We used radioimmunoassay to detecet the content of ACTH in rat's plasma and immunocytochemistry to detecet the expression of ACTH in pituitary. Results The content of ACTH in the group of the Triptolide had significant difference as compared with control group.The expression of ACTH in the group of the Triptolide was higher than that of control group. Conclusion These results suggested that one of the possible mechanism of the Triptolide in the HPAA might be exciting pituitary ACTH neurons,thus causing the content of ACTH increasing.

Objective To evaluate the clinical value of the condition of radial artery for autogenous arteriovenous fistula ostomy by color Doppler ultrasound. Methods The condition of radial artery of 133 end-stage renal disease( ESRD) patients who received autogenous arteri-ovenous fistula ostomy were detected by color Doppler ultrasound,and compared with the postoperative parameters of fistula vascular. Results Among all 133patients,the preoperative radial artery of 95 cases were normal,abnormal in 38 cases. Ostomy surgery performed on 131 cases. Two cases gave up surgery for the poor condition of radial artery,13 cases with fistula failure. The success rate with normal radial artery (95. 8%) was higher than that with the abnormal radial artery(75%). The blood flow parameters of normal radial artery were significantly better than those of the abnormal radial artery,and 4 weeks after operation,the anastomotic blood flow and blood vessel diameter were better than those 1 week before and after surgery. Conclusion Color Doppler ultrasound that can provide preoperative data of radial artery, predict postoperative the state of fistula vascular,and monitor the conditions of postoperative fistula vascular,with better clinical value.

The effects of D-polymannuronic sulfate (DPS) on the norepinephrine (NA) or potassium chloride (KCL)-induced contraction of rat aortic rings were studied in this paper. The results showed that DPS at the final concentration of Img ? L-1 inhibited the contraction of aortic rings e-voked by NA or KCL and shift doseresponse curves for NA or KCL to the right in a non-parallel fa-sion and depressed their maximal response, implicating that DPS afforded the noncompetitive antagonism on contraction of rat aortic rings induced by NA or KCL. This finding suggested that DPS exerted an inhibitory action of potential-dependent calcium channel and that of receptor-operated calcium channel in vascular smooth muscle.

Objective To study the effects of nicotine on GDNF and dopamine content in striatum of Parkinson's disease (PD) rats.Methods 6-OHDA was stereoscopically injected to right side of the mesencephic ventral tegmental area (VTA) and substantia nigra pars compacta (SNpc). Nicotine of different dosages was intraperitoneally injected into PD rats.With biochemical,immunohistochemical techniques, we observed the changes of GDNF expression and dopamine content in striatum.Results Nicotine was intraperitoneally injected into PD rat models before or after the operation,striatum GDNF expression and DA content had significant improvement as compared with PD group (P

When adult developmental dysplasia of hip (DDH) patients have developed secondary os- teoarthritis of hip (OAH) with serious clinical symptoms,total hip replacement (THR) is their first choice of treatment.The anatomic structures of the acetabulum and femur in these patients are ahnormal and special,such as small and shallow cup,small femoral head,and narrow medullary cavity at proximal femoral shaft.As a result,the THR for DDH patients is quite different from the conventional ones and is thus highly difficult.We review in this paper the clinical classification of DDH,which is important for its treatment,the difficulties we will have in THR, especially in acetabular reconstruction and femoral prosthesis placement,and also strategies to resolve them.
