Objective To investigate the efficacy of ultrasound?guided iliohypogastric∕ilioinguinal nerve block and transversus abdominis plane block for analgesia after cesarean section. Methods Ninety parturients, aged 20-40 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective cesarean section, were divided into 3 groups ( n=30 each) using a random number table:con?trol group (group C), ultrasound?guided iliohypogastric∕ilioinguinal nerve block group (group IH∕II) and ultrasound?guided transversus abdominis plane block group (group TAP). In IH∕II and TAP groups, bilat?eral ultrasound?guided iliohypogastric∕ilioinguinal nerve block and transversus abdominis plane block were performed after surgery, respectively, with 0.5% ropivacaine 1.5 mg∕kg ( the maximal dose 100 mg) plus dexamethasone 5 mg for each side. All the patients received patient?controlled intravenous analgesia with morphine after surgery, and numeric rating scales scores at rest and during movement were maintained<4 within the 48 h after surgery. The cumulative consumption of morphine was recorded at 6, 12, 24, 36 and 48 h after surgery. The occurrence of adverse reactions such as nausea, vomiting, pruritus, over?sedation and respiratory depression was observed and recorded in the analgesic period. Results Compared with group C, the cumulative consumption of morphine was significantly decreased at each time point in IH∕II and TAP groups ( P<0.01) . Compared with group IH∕II, no significant change was found in the cumulative consumption of morphine at 6 and 12 h after surgery, and the cumulative consumption of morphine was sig?nificantly increased at 24, 36 and 48 h after surgery in group TAP ( P<0.05) . No nausea, vomiting, pru?
ritus, over?sedation and respiratory depression was found in IH∕II and TAP groups. Conclusion For par?turients, ultrasound?guided iliohypogastric∕ilioinguinal nerve block and transversus abdominis plane block both can provide analgesic efficacy after cesarean section, and the efficacy of the former one is better.

ObjectiveTo investigate the expression and distribution of Toll-like receptor 4 (TLR4) in renal tissue of HBV associated nephropathy (HBV-GN) and its role in the pathogenesis and clinical manifestations of HBV-GN.MethodsRenal tissues were sampled from 48 HBV-GN patients confirmed by renal biopsy and 154 non-HBV-GN patients.The distribution of TLR4 in renal tissue and the relationship between the distribution of TLR4 and HBsAg were detected by immunohistochemistry.Integrating case record,correlations between the expression of TLR4 with clinical parameters including pathology,glomeruli,kidney tubules lesions,renal interstitial inflammatory infiltration and blood serum HBV were analyzed.ResultsTLR4 mainly distributed in the renal tubular epithelial cells and interstitial areas as brownish red and granular,which was in consistent with HBsAg distribution.The TLR4 positive rate and score in HBV-GN group were higher than those in non-HBV-GN group (P ＜ 0.05 ).TLR4 positive score was slightly higher in mesangial proliferative glomerulonephritis group and focal segmental glomerulosclerosis group,which had no significant difference (P ＞ 0.05).Kidney tubules lesions were strongly associated with TLR4 expression (r =0.748,P ＜ 0.001 ) which increased with aggravation of renal interstitial fibrosis ( r =0.569,P ＜0.001 ),tubular atrophy ( r =0.577,P ＜ 0.001 ) and inflammatory cell infiltration ( r =0.684,P ＜0.001 ).No obvious correlation with glomeruli lesions was observed ( r =0.293,P =0.053 ).Negative correlation could be seen between TLR4 and the renal function ( R2 =0.784),systolic blood pressure ( R2 =0.869),high sensitivity C-reactive protein (R2 =0.979) and urinary protein (R2 =0.615 ) by regression analysis.Other clinical parameters had no statistical significances.ConclusionsThe expression of TLR4 is abnormal in the renal tissue of HBV-GN patients,mainly in renal tubular epithelial cells and interstitial,which is consistent with the distribution of HBsAg.Its intensity is closely related with renal interstitial lesions,renal function changes and inflammatory cell infiltration.A speculation,that HBV can promote abnormal expression of TLR4 in renal tissues of HBV-GN which may be involved in the lesion progress of HBV-GN,is made upon our study.

Objective To analyze the clinical manifestations of early cerebral ischemic lesions after stenting with WingSpan system for symptomatic intracranial artery stenosis, and to evaluate the early effects and safety of the stenting therapy. Methods Twenty-nine consecutive patients with symptomatic intracranial stenosis underwent diffusion weighted imaging (DWI) before and after stenting (within 72 hours). The clinical data, including patients' general condition, stenting procedures and newly-developed cerebral ischemic lesions, were recorded. Neurological defect was estimated with NIHSS, the safety and early outcome of stenting were evaluated. Results The degree of stenosis was reduced from a mean baseline of (72.3 ± 10.7)% to (31.9 ± 13.6)% immediately after stenting. The technical success rate was 100%. The total eomplicatiom nate was 17.2%. And among them, z were symptomatic (6.9%). Sixty-three ischemic lesions were demonstrated on DWI in 13 patients (44.8%). Among them, 11 (84.6%) were asymptomatic. Fifty-five newly-developed lesions on DWI (87.3%) were located in the region of stented vessels and 3.2% were situated in the region of branch vessels of stented artery. Conclusion DWI is of great value in assessing the safety of intracranial stenting procedures. The treatment of symptomatic intracranial artery stenosis by using WingSpan system is safe and effective. Newly-developed ischemic lesions can be well detected on DWI and should receive physician's attention, although most ischemic lesions are asymptomatic. Long-term outcome of this treatment needs to be further observed.
