Objectives: Observe the effects of acupuncture on obese SD rats fed by self-prescribed high calorie diet. 　Methods: The model group were male SD rats fed by self-prescribed high calorie diet, while the control group were male SD rats fed by common roughage. After acupuncture, the changes of some indexes were observed such as eating and drinking amount,body weight,length, Lee index,fattiness in groin and circumrenal areas, TG,TC,BG levels in blood etc.　 Results: The obesity was defined as the average body weight of the model group was 20% heavier than the average body weight in the control group. And the obesity ratio was 56%. The indexes were changed in different degrees with statistic significance after one period of treatment.　 Conclusions: Over-nutrition is one of the causes of obesity. Our high calorie feed for obese rat is reasonable. Acupuncture has obvious therapeutic effects for simple obesity.

Objective Analysis of the etiological factors and the diagnostic methods of fever of unknown origin(FUO)in order to avoid misdiagnosis and missed diagnosis.Methods One hundred and twenty-eight patients with FUO were collected from our hospital.Results A final diagnosis was established in 118(92.2%)patients by using serological methods,bacteriological methods,body fluid test,bone marrow examination,tissue biopsy and diagnositic therapy.Infection(62.5%),connective tissue diseases(16.1%),malignancies(11.0%)were found to be the common causes of the fever in these patients while infection was the main cause of FUO in our research.The major pathogens responsible for the infec tion was bacteria,followed by virus and tuberculosis.Adult Still's disease was the most common connective tissue diseases in these patients.Lymphoma,malignant histocytosis and leukemia were the main forms of malignancy.Conclusion Infectious diseases was the most common cause of FUO while connective tissue disease and malignant tumors are also important in the pathogenesis of FUO.

Objective: To investigate the effect and mechanism of Astragalus Injection (Radix Astragali) on acute murine myocarditis caused by Coxsackievirus B 3. Methods: Acute viral myocarditis was induced in 24 Balb/c mice by injection of Coxsackievirus B 3m (CVB 3m ) intraperitoneally. Half of the mice were administered Astragalus Injection(10g/kg?d). Heart and blood samples were obtained from all mice on the 8th day after CVB 3m infection for histopathological study, detection of myocardial perforin expression by reverse transcription polymerase chain reacton(RT PCR) and measurement of serum CK MB level, respectively. Results: (1) Astragalus treated mice showed a significant reduction in myocardial lesion compared with that in untreated mice. (2) Myocardial perforin expression by semi quantitative RT PCR in Astragalus treated mice was much lower than that in controls(1.10?0.07 vs 1.31?0.12, P

Objective To explore the clinical value of transvaginal three-dimensional color Doppler ultrasound in assessing effects of Chinese herbal drugs on improving endometrial receptivity in patients with thin endometrium.Methods A total of 76 cases of patients diagnosed with thin endometrium in Jiangbei District Hospital of Traditional Chinese Medicine from June 2015 to October 2016 were selected and treated with Chinese herbal prescription for three months.The endometrial thickness,endometrial volume and blood flow indexes before and after treatment were measured by using transvaginal three-dimensional color Doppler ultrasound.Results After 3 months treatment,the endometrial thickness and endometrial volume were increased,and the pulse index (PI) and resistance index (RI) of endometrial blood flow were decreased,compared with those before treatment,there were statistically significant differences(P＜0.05).The results of three-dimensional color Doppler ultrasound indicates that after 3 months treatment the vascularization index (VI),flow index (FI) and vascularization flow index (VFI) were significantly higher than those before treatment,there were statistically significant differences (P＜0.05).Conclusion The Chinese herbal prescription could increase the thickness and volume of endometrium,augment blood supply,and improve endometrial receptivity significantly.Transvaginal color three-dimensional Doppler ultrasound is a convenient and objective method for evaluating clinical efficacy of Chinese herbal prescription in patients with thin endometrium,which has high practical value.

Mucosal adjuvants play important roles in vaccine development. By now, the common used mucosal adjuvants can be divided into three categories: the bacterial derivatives, cytokines and chemokines, and antigen delivery systems. Progresses of the three kinds of adjuvants were reviewed to give a reference to novel vaccine research.

Objective To observe the effects of chronic arsenic exposure on estrogen receptor-binding fragment-associated gene 9 (Ebag9) and estrogen-responsive finger protein (efp) mRNA expression in female rat' s myocardium.Methods Fifty female Wistar rats were randomly divided into five groups according to arsenic (As2O3) concentrations in drinking-water:0.00(control),0.05,0.10,0.20,0.40 mg/L groups and RT-PCR was used to detect Ebag9 and efp mRNA expression of myocardium at the 32 weeks of experiment.Results Ebag9 and efp mRNA expression levels in 0.00,0.05,0.10,0.20,0.40 mg/L groups were respectively as follows:0.54 ±0.14,0.52 ± 0.10,0.48 ± 0.24,0.58 ± 0.13,0.45 ± 0.19 and 0.85 ± 0.14,0.86 ± 0.12,0.87 ± 0.09,0.99 ±0.10,0.86 ± 0.19.Compared to the control group,Ebag9 mRNA level of the 0.20 mg/L group was increased,and decreased in other groups,but the difference between two groups was not significant(all P ＞ 0.05).Compared to control group,the efp mRNA level of 0.20 mg/L group increased significantly(P ＜ 0.05),and showed increased tendency in other arsenic groups,but the difference between two groups was not significant (all P ＞ 0.05).Conclusions Ebag9 and efp mRNA expression have changed in myocardium of rats exposed to chronic arsenic.Arsenic may has endocrine disruptor effect to female rat's myocardium.

Objective: To investigate applicability for Boston naming test (30 items) (BNT) in Chinese elderly and identify effect for mild cognitive impairment (MCI) and Alzheimer's dementia(AD) using BNT. Methods:100 normal elderly, 38 amnesic MCI, 34 mild AD and 38 moderate AD were evaluated by neuropsychological tests (include BNT, mini mental state examination and auditory verbal memory test, etc). MMSE total score of 4 groups were 28.4?1.5, 26.1?2.6, 20.7?1.7, and 15.6?3.3, respectively. Results: Age, sex, level of education were found to be significant factors affecting overall scores of spontaneous naming in normal elderly group. Spontaneous naming score for participants of elementary, high school and college groups were 22.2?3.3, 25.5?2.5 and 26.3?1.8, respectively. Scoring of male participants higher than that of females. Spontaneous naming score of 4 groups were 24.9?3.0, 20.9?3.6, 18.7?4.0 and 15.7?4.2, respectively. As cut-off ≤22 score of spontaneous naming of BNT, the sensitivities for MCI, mild AD and moderate AD were 61%, 79% and 95% respectively; the specificities were all around 81%. Selective impairment of unfamiliar items occurred MCI and mild AD and hold of familiar item across diagnostic groups. Semantic cue naming and recognition ability by BNT showed there was progressive damage in AD patients, but less than that of spontaneous naming of BNT. Conclusion: The ability of naming is influenced by age, gender and educational level. Patients with MCI or mild AD have impairment in naming.

Purpose To analyze the ultrasound manifestation of ovarian malignant teratoma, and to evaluate its diagnostic value and explore reasons for its misdiagnosis. Materials and Methods A retrospective study was conducted on the ultrasound findings of 25 patients with ovarian malignant teratoma confirmed surgically and pathologically (22 with immature teratoma, 3 with teratoma with malignant transformation). Their ultrasound imaging features were summarized and the reasons for misdiagnosis were further analyzed. Results The ultrasound imaging of 22 immature teratoma cases were divided into three types, namely, predominant solid components, predominant fluid components and mixed components of fluid and solid. All displayed calcification-like strong echo scattering in the low echo;color Doppler showed rich blood signal, little signal or no blood flow signal. Preoperative ultrasound presented1 case of immature teratoma (4.5%), 8 cases of ovarian tumors (malignant) (36.4%) and 13 cases of other diagnosis (59.1%). As to the 3 cases of teratoma with malignant transformation, the ultrasound imaging showed 2 cases were composed by fluid and solid components and that 1 case was mature cystic teratoma;typical hypoecho suggested malignant transformation. Preoperative ultrasound did not present teratoma with malignant transformation. Conclusion The ultrasound findings of ovarian malignant teratoma seem to be complicated and variable;thus the preoperative diagnosis rate is low though it still shows certain characteristics.
