OBJECTIVETo compare the clinical efficacy difference between electroacupuncture (EA) at qijie area combined with spine balance-regulating massage and medication for posterior circulation ischemia (PCI).

METHODSOne hundred cases of PCI were randomly divided into a treatment group (50 cases) and a medication group (50 cases). The treatment group was treated with EA at Baihui (GV 20), Sishencong (EX-HN 1), Fengchi (GB 20), Shenshu (BL 23), Danzhong (CV 17), etc. in qijie area combined with spine muscle-relieving massage and comprehensive chiropractic. The medication group was treated with oral administration of nimodipine (30 mg per time, three treatments per day) and vinpocetine injection with 500 mL of glucose injection or intravenous drip of 500 mL 0.9% sodium chloride injection, once a day. Ten treatments were taken as one course in both groups, and two courses were given. The symptom score, mean resistance index (RI) of vertebral artery (VA) and basilar artery (BA), mean velocity of blood flow (Vm) and comprehensive clinical efficacy were compared before and after treatment in two groups.

RESULTSThe cured and markedly effective rate was 79.6% (39/49) in the treatment group, which was superior to 54.7% (23/42) in the medication group (P<0.05). The symptom score was both significantly improved after treatment in two groups (both P<0.05), which was more obvious in the treatment group (P<0.05). The RI of VA and BA, Vm of VA and BA were significantly improved after treatment in two groups (all P<0.05), which were more obvious in the treatment group (all P<0.05).

CONCLUSIONThe electroacupuncture combined with spine balance-regulating massage has superior effect on improving mean velocity of blood flow and resistance index of vertebral artery and basilar artery as well as symptom score to medication, and is believed to be a safe and effective treatment for posterior circulation ischemia.

OBJECTIVETo compare the difference in the clinical efficacy on primary trigeminal neuralgia (PTN) between the comprehensive therapy of electroacupuncture (EA) at qi streets acupoints combined with spinal regulation method and medication with carbamazepine (CBZ).

METHODSSixty patients were randomized into a comprehensive therapy group (30 cases) and a medication group (30 cases). In the comprehensive therapy group, the acupoints at qi streets on the head such as Taiyang (EX-HN 5) and Sishencong (EX-HN 1) and those at qi streets on the chest and abdomen such as Shenshu (BL 23), Zhongwan (CV 12) and Guanyuan (CV 4), etc. were selected. After arrival of qi, EA was attached on 2 to 4 groups of acupoints. After acupuncture, the spinal regulation method was applied. This comprehensive therapy was given once a day. In the medication group, CBZ was used for oral administration, 100 mg at the first time, twice a day, and 400 to 600 mg each day as the maintenance dose. Separately, before and after treatment, in 2 and 6 months in follow-up, pain rating index (PRI), life satisfaction index B (LSI-B) and hamilton depression scale (HAMD) were adopted to evaluate comprehensively the clinical efficacy in the two groups and compare the adverse reaction during the treatment between the two groups.

RESULTSAfter treatment, the curative and markedly effective rate in the comprehensive therapy group was 76.7% (23/30), which was better than 63.3% (19/30) in the medication group (P < 0.01). The difference in PRI was not significant after treatment between the two groups (all P > 0.05). In 2 and 6 months follow-up, PRI grade in the comprehensive therapy group was superior to that of the medication group (both P<0. 05). After treatment and in follow-up, HAMD score was all reduced in the two groups (P < 0.01, P < 0.05) and the result in follow-up in the comprehensive therapy group was significant as compared with that in the medication group (all P<0. 05). After treatment, LSI-B score was increased obviously in the two groups (all P < 0.05) and the result in the comprehensive therapy group was better than that in the medication group (P < 0.05). The incidence of adverse reaction in the comprehensive therapy group was 16.7% (5/30), which was lower than 30.0% (9/30, P < 0.01) in the medication group.

CONCLUSIONThe comprehensive therapy of EA at qi streets acpoints combined with spinal regulation method achieves the long-term efficacy on PTN as compared with oral administration of CBZ in terms of the improvement of psychological condition, analgesia and life quality. It is the safe, effective and stable therapy.

OBJECTIVETo explore morphological character and clinical significance of superior-posterior acetabular wall by anatomically measuring and quantitatively analyzing thickness of posterior acetabular wall, then provide a theoretical reference for clinical treatment of acetabular fracture.

METHODSFifteen adult formalin-preserved cadaveric pelvises (8 males and 7 females) were used for this investigation. Excess soft tissue was removed and the whole acetabular posterior walls were marked with "angle" sector method and the thickness was measured with caliper in different levels of the different split points. The measurement results were validated and analyzed statistically.

RESULTSAt 5 mm away from acetabular rim, the average thickness of superior-posterior acetablar wall fluctuated between (6.47±0.61) mm and (7.43±0.71) mm; the average thickness of inferior-posterior acetabuluar wall fluctuated between (5.62±0.51) mm and (6.33±0.61) mm; the average thickness of acetabular roof fluctuated between (7.71±0.74) mm and (8.27±0.99) mm. There was no statistical difference between average thickness of superior-posterior wall of acetabulum and inferior-posterior wall of acetabulum (P>0.05), but the average thickness of acetabular roof was significantly larger than superior-posterior acetabular wall (P<0.05). At 10 mm away from the acetabular rim, the average thickness of superior-posterior acetabular wall fluctuated between (8.81±0.67) mm and (13.35±0.89)mm; the average thickness of inferior-posterior acetabular wall fluctuated between (7.02±0.63) mm and (7.66±0.69) mm; the average thickness of acetabular roof fluctuated between (14.46±0.97) mm and (17.05±1.35) mm. Comparatively, the average thickness of superior-posterior acetabular wall was significantly larger than inferior-posterior wall of acetabulum (P<0.05), and the average thickness of acetabular roof was significantly larger than superior-posterior acetabular wall (P<0.01). At 15 mm away from the acetabular rim, the average thickness of superior-posterior acetabular wall fluctuated between (12.08±0.78) mm and (19.84±1.03) mm; the average thickness of inferior-posterior acetabular wall fluctuated between (10.17±0.76) mm and (11.12± 0.77) mm; the average thickness of acetabular roof fluctuated between (23.23±1.12) mm and (26.01±1.53) mm. Comparatively, the average thickness of superior-posterior wall of acetabulum was significantly larger than inferior-posterior acetabular wall (P<0.01), and the average thickness of acetabular roof was significantly larger than superior-posterior acetabular wall (P< 0.01).

CONCLUSIONThe thickness of entire acetabular posterior edge revealed an increasing tendency from inferior-posterior wall to the superior-posterior wall to acetabular roof. And this trend became more obvious with increasing distance away from acetabular rim. Therefore, the superior-posterior acetabular wall could not only maintain the stability of hip joint but also bear loading.

OBJECTIVETo examine the association of dietary patterns with chronic diseases and their indicators.

METHODSUsing the data from 2002 National Nutrition and Health Survey, we divided the subjects into clusters according to their dietary patterns classified by different percentage of energy intake from cereal foods, carbohydrate and fat, respectively. The analysis of variance was used to identify the difference in chronic disease prevalence across clusters of subjects while controlling for age, gender and geographic regions. Logistic regression analysis was applied to calculate the odd ratios (OR) for association of chronic disease and each dietary pattern, after adjusted for age, gender, region, energy intake, leisure time.

RESULTSThe higher percentage of energy intake from cereals was significantly associated with lower body mass index (BMI), lower total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C). While it was significantly associated with lower risk for overweight/obesity, hypertension, high total cholesterol, high triglyceride (TG) and high LDL-C, but the prevalence of underweight was significantly higher in the cluster of subjects with cereal energy share more than 75%. The higher percentage of energy intake from fat was significantly associated with higher BMI, higher total cholesterol and higher LDL-C, which accordingly, was significantly associated with higher risk for overweight/obesity, hypertension, high total cholesterol, triglyceride and high LDL-C.

CONCLUSIONOur study confirmed the important role of dietary pattern in chronic disease control; in particular, appropriate percentage of energy intake from fat and cereals/carbohydrates are beneficial to control and prevention of chronic diseases.

The present study was designed to observe the influence of cerebral ischemia/reperfusion injury on learning and memory in hyperlipidemic rats and estimate the changes of activity of autonomic nervous system. Twenty-three male Wistar rats were randomly divided into three groups, named control group (C group, n=10), hyperlipidemia group (H group, n=6) and hyperlipidemia-ischemia group (HI group, n=7), respectively. The rats in H and HI group were fed a high-fat diet for 2 weeks and the rats in all groups were examined through Morris water maze (MWM) task. The rats in HI group underwent ischemia/reperfusion by 2-vessel occlusion (2-VO) method, and had electrocardiogram (ECG) recording simultaneously. The MWM task and ECG recording were taken again after 7 d of recuperation. The following results were obtained: (1) In the second place navigation performance and probe trial performance, the frequency of memory in quadrant of hidden-platform and memory score decreased significantly in HI group compared to that in C and H groups. (2) The heart rate in HI group decreased slowly after ischemia; the power at high frequency band (HF) reduced gradually, meanwhile the power at middle frequency band (MF) and the ratio of power at MF and HF decreased clearly compared to baseline value. (3) After 7 d of ischemia/reperfusion, the heart rate in HI group was significantly higher than that in H group (P<0.05). While there was no statistical change in the power at MF, the power at HF decreased and the ratio of MF/HF increased significantly (P<0.05). The data demonstrated that ischemia/reperfusion decreased the activity of autonomic nervous system, and the reduction of sympathetic nerve activity was much more than that of vagus nerve activity. The results suggest that the hippocampus neuron injury caused by ischemia induces cognitive disorder and imbalance of vago-sympathetic nerve activity accompanied by vagus nerve suppression.
