Objective To observe the effects of 860 MHz microwave radiation on an established dual task model of trace and delay eyeblink conditioning in guinea pigs.Methods Twenty-four guinea pigs with an established dual task model of trace and delay eyeblink conditioning were assigned randomly into four groups : a microwave-exposed 1 h group, a microwave-exposed 20 min group, a sham-exposed group and a normal control group.The guinea pigs in the 1 h and 20 min groups were irradiated on the head daily for 3 days using 860 MHz electromagnetic radiation at a power density of 1 mW/cm2 for 1 h and for 20 min, respectively. After radiation the guinea pigs were trained with classical dual task eyeblink conditioning.Results Compared with the normal control group, the behavioral parameters (acquisition rate and peak amplitude of trace and delay eyeblink) of guinea pigs in the microwave-exposed 1 h group had decreased significantly with no obvious change in latency. The behavioral parameters of guinea pigs in the microwave-exposed 20 min group, the sham-exposed group and the normal control group showed no obvious change.Conclusions Microwave radiation at 860 MHz and 1.0 mW/cm2 for 1 h can cause changes in dual trace and delay eyeblink conditioning in guinea pigs and decrease learning and memory capacity.

OBJECTIVETo explore the advantages and indications of the paraspinal approach by anatomical study and clinical application.
METHODSThe anatomical data and clinical practice of 27 cases were analyzed to explore the accurate approach between the paraspinal muscles and the structure of ambient tissues, as well as the results of clinical application of paraspinal approach. The operation time, blood loss, incision length, radiographic result (Cobb angle, height of anterior edge of the vertebrae) were compared with those in 24 cases treated by traditional approach.
RESULTSComplete exposure of the facets could be easily performed by identifying natural cleavage plane between the multifidus and longissimus muscles. The natural muscular cleavage was (1.47+/-0.23) cm lateral to the midline for females, and (1.64+/-0.35) cm for males at T(12) level. The distance was (3.3+/-0.6) cm lateral to the midline for females, and (3.7+/-1.0) cm for males at L(4) level. In paraspinal approach group, the operation time was (76.2+/-15.7) min, blood loss was (91.6+/-16.9) ml and incision length was (7.6+/-0.8) cm. In traditional approach group, the operation time was (121.4+/-19.6) min, blood loss was (218.7+/-32.3) ml and incision length was (17.4+/-2.1) cm. To compare paraspinal approach with traditional approach, the operation time, blood loss and incision length had statistical difference (P less than 0.05) and the radiographic result (Cobb angle, height of anterior edge of the vertebrae) had no statistical difference (P larger than 0.05).
CONCLUSIONSWhen the paraspinal approach is performed through natural cleavage plane between the multifidus and longissimus muscles, there are no wide muscular disinsertions, leaving the supraspinous and interspinous ligaments intact. The distance of natural cleavage to the midline is different at T(12) and L(4) planes. By this approach, the facet joints can be explored easily and completely, and a clear surgical field will be available for the placement of pedicle screws. As a minimally invasive approach, it can be widely used in thoracolumbar spine surgery.

PURPOSE: Insulin resistance plays a role in the development of dementia and hypertension. We investigated a possible relationship between cognitive impairment and insulin resistance in elderly Chinese patients with primary hypertension. MATERIALS AND METHODS: One hundred and thirty-two hypertensive elderly patients (>60 years) were enrolled in this study, and assigned into either the cognitive impairment group (n=61) or the normal cognitive group (n=71). Gender, age, education, body mass index (BMI), waist hip ratio (WHR), total cholesterol (TC), triglyceride (TG), C-reactive protein (CRP), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), creatinine (Cr), fasting plasma glucose (FPG), fasting insulin (FINS), homeostasis model of assessment for insulin resistance index (HOMA-IR), systolic blood pressure, diastolic blood pressure, smoking history, atherosclerosis and the proportion of uncontrolled hypertension were compared between the two groups. Multi-factorial logistic regression analysis was performed. RESULTS: No significant differences were found in gender, age, TC, CRP, HDL-C, LDL-C, Cr, BP, smoking history, atherosclerosis and the proportion of uncontrolled hypertension between the two groups. The cognitive impairment group had lower education levels, and higher BMI, WHR, TG, FPG, FINS, and HOMA-IR levels than the control group. Logistic regression analysis revealed the levels of education, BMI, WHR, and HOMA-IR as independent factors that predict cognitive impairment in patients. CONCLUSION: Our study demonstrates that poor education and increased BMI, WHR, and HOMA-IR are independent risk factors for cognitive impairment in elderly patients with hypertension. Insulin resistance plays an important role in the development of cognitive impairment in primary elderly hypertensive patients.

OBJECTIVETo observe the antagonist effect of Curcuma Aromatica (CA) on renal tubular epithelial-myofibroblast transdifferentiation (EMT) induced by transforming growth factor-beta1 (TGF-beta1).
METHODSNormal renal tubular epithelial NRK-52E cells in vitro cultured were randomly divided into 6 groups, i.e., the normal control group (Group C), the TGF-beta1 induced model group (Group T), the low dose CA treated group (Group E1), the moderate dose CA treated group (Group E2), the high dose CA group (Group E3), and the Benazepril Hydrochloride Tablet treated group (Group Y). Except Group C, corresponding medication (with an action of 48 h) was administered to cells in the rest groups after they were induced by TGF-beta1 for 24 h. The morphological changes were observed by inverted phase contrast microscope. The distribution of beta-actin protein was detected by immunohistochemical assay. The mRNA expressions of alpha-smooth muscle actin (alpha-SMA) and E-cadherin (E-cad) were detected by real-time PCR. The concentration of fibronectin (FN) was detected by ELISA.
RESULTSAfter induced by TGF-beta1 for three days, hypertrophy and elongated cells in fusiform-shape occurred,with increased expressions of beta-actin protein in the cytoskeletal structure (P < 0.05), bundle fibrous structure occurred inside cytoplasm with significantly up-regulated intracellular alpha-SMA mRNA expressions (P < 0.05), E-cad mRNA expression decreased (P < 0.05), the FN content in the supernate increased (P < 0.05) in Group T. Compared with Group T, partial cells in Group E1, E2, and E3 showed fibrous changes, accompanied with decreased expression of beta-actin protein and FN concentration (P < 0.05). The expression of alpha-SMA mRNA increased and the expression E-cad mRNA decreased in Group E2 and E3 (both P < 0.05). But there was no statistical difference in the expression levels of E-cad and alpha-SMA mRNA (P > 0.05). Compared with Group E1, the expression of beta-actin protein and FN concentration decreased in Group E2 and E3 (P < 0.05). The expressions of alpha-SMA mRNA decreased and E-cad mRNA increased in Group E3 (P < 0.05). Compared with Group Y, the expression of beta-actin mRNA and FN concentration increased in Group E1 (P < 0.05); the expression of beta-actin mRNA increased in Group E3 (P < 0.05); the expression of E-cad mRNA decreased in Group E3 (P < 0.05). There was no statistical difference in the expression of alpha-SMA mRNA among Group E1, E2, and E3 (P > 0.05).
CONCLUSIONCA could inhibit the occurrence of TGF-beta1 induced EMT, which could be used as an effective drug for treating chronic renal insufficiency.
