Objective To investigate the effect of acupuncture at the primary points of the three yin meridians of the foot on blood pressure in an animal model of high/low blood pressure and explore the specific effect of the meridian points-the primary points of the three yin meridians of the foot.Methods The study included the parts of hypertension and hypotenstion. Both parts were allocated to the primary points of the three yin meridians of the foot, non-acupoint, model and blank groups, six rats each. Except the model and blank groups, all the groups were given acupuncture treatment for seven consecutive days. Blood pressure was measured after the completion of treatment. Five consecutive measurements were made in each rat. Mean values of blood pressure were taken.Results For the part of hypertension, blood pressure at each time point was higher in the acupuncture groups than in the blank control group and lower than in the model group, and there were statistically significant differences (P<0.05), indicating that acupuncture at the primary points of the three yin meridians of the foot has a hypotensive effect. The hypotensive effects of Taichong and Taixi were better than those of Taibai and the non-acupoint (P<0.05). The hypotensive effects of Taichong and Taixi were equal (P>0.05). The hypotensive effect of Taibai was equal to that of the non-acupoint (P>0.05). For the part of hypotension, blood pressure at each time point was lower in the acupuncture groups than in the blank control group and higher than in the model group, and there were statistically significant differences (P<0.05), indicating that acupuncture at the primary points of the three yin meridians of the foot has a pressor effect. The pressor effect was worse in the the non-acupoint group than in the primary points of the three yin meridians of the foot group (P<0.05). The pressor effects of Taibai and Taixi were equal but worse than that of Taichong (P<0.05).Conclusions Acupuncture at the primary points of the three yin meridians of the foot has a specific bidirectional regulating effect on blood pressure. Of them, point Taichong produces a best bidirectional regulating effect on blood pressure.

Objective To sum up the experience on diagnosis and treatment of Hashimoto disease and its concurrent thyropathy. Methods Clinical data were analyzed on 52 cases of Hashimoto disease(HD) surgically found to have concurrent thyropathy from Jan 1984 to Jun 2001 out of 138 HD cases undergoing surgery. Results Thyroid nodules were found in all 52 HD cases, among which 17 were with thyroid cancer, 2 with malignant lymphoma, 5 with thyroid adenoma, 2 with hyperthyroidism, and 26 with nodular goiter. Thyroidectomy of different extent was performed. Postoperatively all cases were given thyroxine. On follow-up a patient with malignant lymphoma died, and one patient suffered hypothyroidism. Conclusion HD is a ubiquitous disease. The clinical diagnosis of is still difficult. HD cases complicated with thyroid nodules should be treated surgically to exclude malignant tumors. Intraoperative frozen section is a reliable diagnostic method and may guide the surgical modality.

Purpose: To investigate a clinical treatment for allergic asthma. Method: Acupoint application was used, and its effect was compared with that of Western medicine to evaluate the results. Results and Conclusion: It was found that the long-tern effect of acupoint application was significantly better than that of aminophylline; acupoint application had obviously different effects on different types of asthma based on TCM differentiation of syndromes; its short-term effect was not significantly related to the course and condition of the disease. It is indicated that acupoint application is an effective, convenient and safe treatment with little side effect for asthma.

The changes of some parameters of Gray type Ⅰ synaptic interface in the brain of mice treated with desglycinamide-arginine-8-vasopressin (DGAVP) have been analysed quantitatively two hours after DGAVP injection. The animals were killed and the hippocampus and sensori-motor area of cerebral cortex were prepared for electron microscopy. The electron microphotographs were analysed by IBM-PC computer image processing system. The main results of the experiment are as follows:1. The thickness of postsynaptic density apparently increased in both the sensori-motor area of cerebral cortex and CA_3 area of hippocampus after injection of DGAVP (P

Objective To explore the action mechanism of shenxiong glucose injection in treatment of acute spinal cord injury(SCI) through observing its effects on the recovery of motor function and the expression of aquaporin-4(AQP-4) in SCI rats.Methods Totally 90 healthy,aduh,Sprague-Dawley rats were randomly divided into a sham operation group (n=30),aSCI group (n=30) and a drug group (n=30).The SCI rat models in both the SCI group and the drup group were established aecording to the modified Allen's method,while the sham operation group was only given laminectomy.After the operation,the drug group was given intraperitoneal shenxiong glucose injection of 30 rnl/kg a day,while the other two groups were injected in the same way with normal saline.The neural function recovery,the pathological changes after SCI and the expressions of AQP-4 were observed 1,3,7,14 and 21 d after the operation using the Tarlov score,the hematoxylin and eosin staining,as well as immunofluorescence techniques and Western blotting.And the correlation of Tarlov scores with AQP-4 expressions was analyzed.Results No significant changes in Tarlov scores were observed in the sham operation group (P ＞ 0.05),while in the SCI group and the drug group,postoperative Tarlov scores decreased significantly.The hindlimb nerve function recovered to some degree with time in the SCI group and drug group.At 3,7,14 and 21 days after the operation,the Tarlov scores in the drug group were significantly higher than the SCI group (P ＜ 0.05).The drug group showed less severe pathological changes,with more residual neurons still visible of nucleoli than the SCI group 21 days after the operation.Compared with the sham operation group,the expression levels of AQP-4 were significantly higher in the SCI group and drug group at all the time points (P ＜ 0.05).However,the expression levels of AQP-4 in the drug group were significantly lower than the SCI group accordingly (P ＜ 0.05).The Tarlov scores were found to be significantly and negatively related to the AQP-4 protein expression levels 3 days(r =-0.523,P =0.003),7 days(r =-0.437,P=0.016),14 days(r=-0.417,P=0.022) and 21 days(r=-0.377,P=0.040)after the operation.Conclusion Injecting shenxiong with glucose can effectively promote the recovery of motor function after SCI,at least in rats.And its mechanism may be that the development of spinal cord edema is prevented and the secondary spinal cord injury alleviated by restraining the expressions of AQ P-4 in the injured areas.

Objective To observe the antibacterial and synergistic effect of Xianglian Suppository with miconazole suppository for the treatment of simple vulvovaginal candidiasis ( VVC) , and to explore the advantages of integrative Chinese and western medicine for the treatment of simple VVC. Methods According to the principle of randomized trial, 65 simple VVC patients were divided into two groups, 35 cases in test group and 30 in control group. The test group was given Xianglian suppository and miconazole suppository, and the control group was treated with miconazole suppository, the medication lasting for 7 days. The changes of symptom scores before and after treatment were observed, and the therapeutic effect and safety were also evaluated in both groups. Results ( 1) After treatment for one course, the markedly effective rate and total effective rate were 60.00%, 88.57% in the test group, and were 23.33%, 60.00% in the control group, respectively, the differences being significant between the two groups ( P<0.01). ( 2) After treatment, symptom scores were decreased in both groups ( P<0.01 compared with those before treatment) , and the decrease in the test group was superior to that in the control group (P<0.01). (3) One case of the test group had the complaint of severer pruritus vulvae after medication, and the results of physical examination showed the case had vulvovaginal flush but had no edema, blister or other discomfort. The manifestations disappeared when the medication continued, indicating that the case had no allergic reaction. No case had allergic reaction in the control group. Conclusion For the treatment of simple VVC, Xianglian suppository combined with miconazole suppository can obviously relieve the clinical symptoms, and is effective and safe.

Objective To investigate the relationship between tumor necrosis factor-α (TNF-α) in ischemic brain tissue and bran edema after cerebral ischemia-reperfusion in rats.Methods Eighty four male SD rats were randomly assigned to either a cerebral ischemia reperfusion group (n =44) or a sham-operation group (n =40). A model of middle cerebral artery occlusion for 120 minutes followed by reperfusion was induced in rats using the suture method. The infarct size was determined by 2, 3, 5-triphenyi terazoloride (TTC) staining at 6 h,24 h, 3 d, and 7 d respectively after the reperfusion. Dry-wet weight method was used to measure brain water content and evaluate the extent of brain edema. The enzyme-linked immunosorbent assay (ELISA) was used to detect the concentration of TNF-α in ischemic brain tissue. Results TNF-α level in ischemic brain tissue was increased at 6 h (445.8 ±91.7 pg/ml) after the reperfusion, and reached the peak at day 3 (715.5 ±121.3 pg/ml). There were significant differences compared to the sham-operation group and other time points (all P＜0.001). After that, it was decreased gradually, but it was still higher than that in the shamoperation group at day 7 (478.1 ± 145.5 pg/ml vs. 148.5 ± 101.7 pg/ml, P＜0.005). The initial change of the water content in brain tissue lagged behind the increased TNF-α. It did not increase significantly until 24 h after cerebral ischemia-reperfusion (P ＜0.001). It reached the peak at day 3 (P ＜0.001), and it was still higher than that in the control group at day 7 (P ＜0.05). The evolution of cerebral infarct volume was in accordance with the changes of TNF-α level. Conclusions TNF-α is associated with the changes of brain edema and infarct volume,and it is harmful to brain tissue.
