The patient presented with dry cough, lending, fever and progressive dyspnea for two weeks. The patient had a prior respiratory infection history and the symptoms were not obvious, Early X-ray showed lung infection. Under the fibrolaryngoscope, the lingual surfaces of the epiglottis, epiglottic vallecula, and bilateral vocal cords were covered by yellow pseudomembrane. The motion of vocal cords was normal with poor glottic closure, and no ulcer was noted. Endotracheal mucosa was swelling and congested with an uneven surface, and purulent discharge and pseudomembrane was formed. Pathological examination revealed Aspergillus. The disease was diagnosed as Aspergillus laryngotracheobronchitis.

Objective To investigate the effect of stellate ganglion block(SGB)on heart mte variability (HRV)during thyroidectomy performed under cervical plexus block.Methods Forty-five ASA Ⅰ or Ⅱ pafients of both sexy8(8 males,37 females) aged 20-60 yr,weighing 40-70 kg undergoing elective thyroidectomy under cervical plexus block were randomly divided into 3 groups(n=15 each):group Ⅰ control,group Ⅱ left SGB and group Ⅲ right SGB.The parameters of HRV included low frequency(LF),high frequency(HF),LFnu,HFnu and LF/HF ratio.SBP,DBP,HB and HRV parameters were recorded before anesthesia(To,baseline),immediately(T1) and at 5 and 10 rain after cervical plexus block(T2,T3),at the beginning and end of operation (T4,T5).Results SBP and DBP were significantly increased at different time points after cervical plexus block in all 3 groups.Compared with the baseline at T0,LFnu and LF/HF ratio were significantly increased while HR,HF and HFnu decreased during operation in group Ⅰ,LF,HF and HFnu were significantly decreased while HR increased during operation in group Ⅲ(P<0.05),but no significant change in HRV parameters was found during operation in group Ⅱ(P>0.05).Compared with group Ⅰ,HR and LFnu were significantly decreased while HF and HFnu increased in group Ⅱ(P<0.05),but no significant change was found in the indexes mentioned abovein group Ⅲ (P>0.05).Conclusion SGB can adjust cervical plexus block-induced sympathetic excitability and maintain the balance between sympathetic and parasympathetic tension.Left SGB outweighs right SGB.

OBJECTIVE:
To investigate the relationship between apoptosis of myocardial cells in spontaneously hypertensive rats (SHRs) and the expressions of Bcl-2 and Bax protein, and the protective effect of stellate ganglion block on apoptosis of myocardial cells.
METHODS:
A total of 32 ten-week-old male SHRs were assigned randomly into 4 groups: a left stellate ganglion block group (group LS), a right stellate ganglion block group (group RS), a captopril group (group D) and a control group (group C). The arterial systolic blood pressure was measured by ALC-NIBP system. After 10 weeks, all rats were anaesthetized by 3% pentobarbital sodium, cardiomyocyte apoptosis index of left ventricle was assessed by TUNEL, and the localization of myocardium Bcl-2, Bax was investigated by immunohistochemistry.
RESULTS:
Compared with group LS and C, the apoptotic index decreased (P<0.05). SHR myocardial expression of Bcl-2 significantly increased (P<0.05), Bax expression significantly decreased (P<0.05) and Bcl-2/Bax was significantly higher (P<0. 05) in group RS.
CONCLUSION
Bcl-2 and Bax play an important role in the apoptosis of myocardial cells in SHRs. Right stellate ganglion block can reduce the apoptosis of myocardial cells and reverse the reconstruction of the left ventricle in SHRs via regulation of apoptosis-related gene proteins.

OBJECTIVE:
To determine the effect of stellate ganglion block on reconstruction of the left ventricle in spontaneously hypertensive rats (SHRs).
METHODS:
Thirty-two 10-week-old male SHRs were randomly assigned into 4 groups: a left stellate ganglion block group (group LS), a right stellate ganglion block group (group RS), a captopril group (group D) and a control group (group C). The arterial systolic blood pressure (SBP) was measured by ALC-NIBP measuring system. After 10 weeks, we observed the left ventricular mass index (LVMI), myocardial pathologic changes, and detected the endothelin (ET-1) and endothelial nitric oxide synthase (eNOS) level in the left ventricle by radioimmunoassay and the collagen protein level in the left ventricle by immunohistochemical method.
RESULTS:
Compared with group LS and group C, the LVMI in group RS was lowered most notably (P<0.05) and pathological changes were improved obviously. The expression of eNOS in group RS was significantly increased and ET-1 significantly decreased (P<0.05) compared with that in group C and group LS. The expression of type I collagen fibers in group RS was significantly lower and type III collagen fibers significantly higher (P<0.05) when compared with that in group C and LS.
CONCLUSION
Right stellate ganglion block can not only decrease the arterial pressure but also reverse the reconstruction of the left ventricle.
