Objective To investigate the feasibility of different doses of dexmedetomidine required to prevent sufentanil-induced cough during anesthesia induction. Methods Two hundred and forty ASA Ⅰ or Ⅱ patients, aged 18-55 yr, weighing 45-78 kg, undergoing elective gynecological operations under general anaesthesia, were randomly divided into 4 groups ( n = 60 each) : Ⅰ -Ⅳ groups. Ⅱ -Ⅳ groups received iv infusion of dexmedetomidine 0.10, 0.25 and 0.50 fig/kg at a rate of 0.05 μg·kg-1·min-1 respectively before anesthesia induction. Anesthesia was induced with target-controlled infusion of propofol (target effect-site concentration 5 μg/ml) , when the BIS value reached 55, iv sufentanil 0.5 fig/kg was injected over 3 s. The occurrence and degree of cough were recorded within 1 min after sufentanil injection. Tracheal intubation was facilitated with succinylcholine 1-2 mg/kg after the observation. The adverse cardiovascular events (severe sinus bradycardia, hypotension) were also record ed from the start of dexmedetomidine infusion to 1 min after intubation. Results The incidences of cough were 25 % , 7 % , 7 % and 5 % , incidences of severe sinus bradycardia 0, 3 % , 15 % and 25 % , and incidences of hypotension 5% , 7% , 8% and 8% in Ⅰ - Ⅳ groups respectively. Compared with group Ⅰ , the incidences of cough were significantly decreased in Ⅱ - Ⅳ groups, while the incidences of severe sinus bradycardia increased in Ⅲ -Ⅳ groups (P ＜ 0.01) . There was no significant difference in the incidences of cough among Ⅱ - Ⅲ groups and in the degree of cough among the four groups (P ＞ 0.05). Conclusion Intravenous dexmedetomidine 0.10 μg/kg can be used to prevent sufentanil-induced cough during anesthesia induction.

The occurrence rate of post-operation nausea, vomiting and abdominal bloating was observed.Result The occurrence rate of nausea, vomiting and abdominal bloating was 11.7% in the treatment group, versus 33.3% in the control group, and the difference was statistically significant (P<0.05).Conclusion Auricular point sticking plus moxibustion at Zusanli (ST 36) is effective in preventing spleen-stomach disharmony due to intravenous analgesia pump, and can reduce pain and complications.

Hereditary renal diseases (inherited kidney diseases) include glomerular diseases,tubular diseases and cystic diseases.The incidence of inherited kidney diseases is relatively low, but the variety of clinical insufficient understanding of the disease, the means test about inherited kidney diseases is also not standardized, easily lead to missed diagnosis and misdiagnosis.As the common clinical manifestation of hereditary renal disease and congenital/hereditary renal disease are mainly low blood potassium, kidney stones, polyuria, growth retardation, and may develop renal failure without treatment.Therefore, clinicians should pay special attention to the diagnosis of congenital/hereditary renal disease, and early interventions are recommended.

Objective To investigate the protective role of Xiongbitong capsule against liver injury in hyperlipemic rats.Methods Sixty Wistar male rats were randomly divided into 5 groups(12 rats in each group): a blank group, a model group, a simvastatin group(10 mg/kg, 2 ml intragastric administration daily), a Xiongbitong capsule high-dose group(25 mg/kg, 2 ml intragastric administration daily), and a Xiongbitong capsule low-dose group(12.5 mg/kg, 2 ml intragastric administration daily). Hyperlipidemia model in rats was indeuced by hyperlipidemic diet. The simvastatin group was intragastric administrated with simvastatin suspension 2 ml(10 mg/kg daily), and the rats in the control group and the model group were intragastric administrated with equal volume of saline. After 10 weeks, the serum leves of total cholesterol(TC), triacylglycerol(TG), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol (HDL-C), nitric oxide(NO), endothelin1(ET-1), and the whole blood viscosities(high-, medium-, low-shear)were measured. Liver injury were evaluated with histopathologic examination by H.E. staining. The expressions of intercellular adhesion molecule-1(ICAM-1), monocyte chemoattractant protein-1(MCP-1)in hepatic tissue were measured by immunohistochemical staining.Results The serum leves of TC(1.47± 0.10 mmol/Lvs. 3.48±0.19 mmol/L), TG(0.38±0.11 mmol/Lvs. 0.95±0.14 mmol/L), LDL-C(1.48± 0.18 mmol/Lvs. 2.39±0.22 mmol/L), ET-1(145.81±18.65 pg/mlvs. 177.70±17.70 pg/ml) in the Xiongbitong capsule high-dose group were significantly lower than those in the model group(allP<0.01), HDL-C(1.21±0.14 mmol/Lvs. 0.65±0.10 mmol/L)and NO(31.28±2.36μmol/Lvs. 19.61±1.28μmol/L) significantly lower than those in the model group(allP<0.01), the expressions of ICAM-1(0.133±0.019vs. 0.187±0.011)and MCP-1(0.153±0.014vs. 0.264±0.020)significantly lower than those in the model group(allP<0.01). The liver injury in the Xiongbitong capsule high-dose group decreased than that in the model group. Conclusions Xiongbitong capsule can protect against liver injury via regulating lipid metabolism, protecting endothelial function and down regulating expressions of MCP-1 and ICAM-1.
