OBJECTIVETo observe and evaluate the clinical effect of acupuncture at "Siguan" combined with the Gallbladder Meridian acupoints on migraine.

METHODSWith randomized controlled trial design, 87 patients were randomly divided into an observation group (42 cases) and a control group (45 cases). The observation group was treated with acupuncture at "Siguan" including Hegu (LI 4) and Taichong (LR 3), combined with the Gallbladder Meridian acupoints including Fengchi (GB 20), Shuaigu (GB 8), Qiuxu (GB 40) and Zulinqi (GB 41), while the control group was treated with acupuncture at the Gallbladder Meridian acupoints, including Fengchi (GB 20), Shuaigu (GB 8), Qiuxu (GB 40), Zulinqi (GB 41), Yanglingquan (GB 34) and Hanyan (GB 4). The treatment was given every other day in two groups, 3 times per week for totally 6 weeks. The migraine intensity, migraine frequency and lasting time of each migraine were observed before and after treatment, and 3-month follow-up was performed after treatment. The clinical efficacy in two groups was evaluated.

RESULTSCompared with those before treatment, the migraine intensity, frequency and lasting time were all reduced significantly after treatment in the two groups (all P<0.01), which were more obvious in the observation group (all P<0.05). At the end of the treatment, the total effective rate was 95.2% (40/42) in the observation group and 80.0% (36/45) in the control group, which had statistical difference (P<0.05). After 3-month follow-up, the total effective rate was 88.1% (37/42) in the observation group and 75.6% (34/45) in the control group, which had no statistical difference (P>0.05).

CONCLUSIONThe "Siguan" combined with the Gallbladder Meridian acupoints could significantly relieve the migraine intensity, frequency and lasting time, and its improvement of symptoms and short-term efficacy are superior to those of the Gallbladder Meridian acupoints alone.

AIM: To observe the humoral immune response in adult rhesus monkey induced by A? 1-15 vaccine. METHODS: 5 adult male rhesus monkeys were injected intramuscularly with A? 1-15 vac cine at baseline and at week 2, 6, 10, 14, 18, 22. The titer and IgG isotypes of the antibody against A? 1-42 in the serum were measured with ELISA. The specificity of the antibody against A? 1-42 was determined by Wester n blotting. The A? plaques in Tg2576 transgenic mouse brain were stained with t he antisera using immunohistochemistry method. RESULTS: At the eighth week after the vaccination, antibody against A? 1-42 bega n to develop significantly i n the serum. The titers of the antibody increased following vaccine boosted and reached 1: 3 840 at the twenty-fourth week, then decreased after the terminat ion o f inocunation. The IgG1 was accounted for the highest level in the antisera pool . The antibody against A? 1-42 showed high specificity. The A? plaques in Tg2576 transgenic mouse brain were labeled with the antisera. CONCLUSION: A? 1-15 vacci ne could induce vigorously specific humoral immune responses in adult rhesus mon key.

Objective To study whether inoculating complete or C terminal fragment of A? 42 vaccine could induce normal rats to produce high titer of antibody against A? 42 or not. Methods The COOH\|terminals(36\|42) of beta\|Amyloid 42 were coupled with different carriers to construct subunit vaccine,which been inoculated in normal SD rats sa did the complete beta\|Amyloid 42.Antibodies against A? 42 of the serum and supernatant of homogenated brain were assessed by Western blottting and indirect ELISA.The morphology of brain,liver,spleen and kidney were observed in paraffin section by HE staining. Results After the second inoculation finished,all experiment groups began to develop antibody against A? 42 ,and the titer raising with inoculating times.After four inoculations,The titers of antibody against A? 42 in every experiment group were over than 1∶10?000.Meantime,low titer of antibody against A? 42 could also be assessed in supernatant of homogenated brain.No morphological damages could be detected in the brain,liver,spleen and kidney of the experiment animals.Conclusion\ Normal SD rats can be induced to develop high titer of antibody against A? 42 after inoculating A? 36\|42 vaccine and A? 1\|42 vaccine.There were no morphological damages in several important organs.\;[

Purpose To explore the correlation between whole body magnetic resonance diffusion-weighted imaging (WB-DWI) quantitative parameters of healthy adults' bone marrow with gender, age, height, weight, body mass index, and sex hormone levels. Materials and Methods 108 healthy adult subjects in different age groups underwent WB-DWI scan using GE 1.5T MR scanner, among them estradiol and progesterone levels were measured in 60 subjects within 48 hours before or after the scan. Apparent diffusion coefficient (ADC) values of bone marrow and the signal to noise ratio (SNR) were compared among different gender and age groups. Partial correlation analysis was used to evaluate the correlation of skeletal system ADC values and SNR with sex, age, height, weight, body mass index, estradiol and progesterone levels in 60 subjects. Results ADC values and SNR of the female subjects were significantly higher than males (P<0.01);there were significantly differences for skeletal system ADC values and SNR in different age groups (P<0.01). Skeletal system ADC values was significantly negatively correlated (r=-0.642, P<0.01) with age, and were mildly positively correlated (r=0.278, 0.271, P<0.05) with estradiol and progesterone levels;SNR was significantly negatively correlated (r=-0.709, P<0.01) with age, and was mildly positively correlated (r=0.293, P<0.05) with estradiol levels;ADC values and SNR had no significant correlation with height, weight and body mass index. Conclusion Skeletal system ADC values are effected by gender, age and sex hormone levels, the skeletal system WB-DWI manifestations are different in different gender and age groups.

Objective To establish an optimal animal model of pulmonary metastasis of human lung adenocarcino-ma, to serve further investigation of mechanism of lung adenocarcinoma metastasis.Methods Eleven nude mice aged 4-6 weeks were used in this study.Suspension of human lung adnocarcinoma A549 cells (0.1 mL, 107 cells/mL) was injec-ted into the tail vein in nude mice.From four weeks after inoculation, two nude mice were killed each time at 4, 5, 6 weeks after the tumor cell injection at random for examination.The remaining 3 mice were killed at the end of the experi-ment.At autopsy, the lung, brain, liver, kidney and other organs were removed, fixed in neutral buffered formalin and embedded in paraffin.Sections were cut and stained with hematoxylin-eosin, and examined by histopathology.The number of metastatic foci was counted.Results No mouse died after tumor cell inoculation.Serially euthanized mice revealed evi-dence of gradually increasing pulmonary metastases in the mice:No metastasis was found before 4 weeks after tumor cell in-oculation, the first histological metastases appeared at 5 weeks, gross metastatic foci were observed at 6 weeks, widely spread metastatic foci were observed at 7 weeks, and the remain 3 mice developed cachesia at 11, 13, and 14 weeks after tumor cell inoculation.Mediastinal lymph node metastases were found in the nude mice by 11 weeks after tumor cell inocu-lation.Conclusions We have successfully established a nude mouse model of pulmonary metastasis by injecting human lung adenocarcinoma A549 cells into the tail vein.

Objective To quantify the benefit of primary Pdmor removal in patients with differently presenting incurable coloreetal cancer,while no other therapy combined.Methods One hundred and forty-three consecutive patients were operated for incurable colorectal cancer(91 undergoing resective and 52 non-resective procedures),with the purpose of comparing homogenous populations and of identifying whether the patients got benefit from primary tumor resection.Results In patients with resectable primary tumors,resective procedures were associated with longer median survival than non-resective procedures(10 months vs 3 months),patients with distant spread without neoplastic ascites/implanting metastasis got benefit from primary tumor removal(P＜0.01).The complication of resective procedures was not significantly differ-ent from that of non-resective procedares(P＞0.05).Conclusion Palliative resection of primary colorectal cancer should be pursued in patients with unresectable distant metastasis whenever the primary tumor is technically resectable.

The experimental researches of applying emodin for prevention and treatment of liver diseases in recent years were reviewed. Emodin can inhibit the growth of liver tumor cells in vitro and in vivo, inducing cell apoptosis is one of its mechanisms. Emodin also has the effects of liver protection, anti-liver fibrosis, and so on, the mechanisms for those effects still need more studies.
