Objective:To compare the antihypertensive effects of tuina at Taichong (LR 3),Neiguan (PC 6) and Qiaogong (Extra) to screen the best tuina protocol for primary hypertension due to liver-fire flaming-up.Methods:A total of 102 patients with primary hypertension due to liver-fire flaming-up were randomly divided into a Taichong (LR 3) group,a Neiguan (PC 6) group and a Qiaogong (Extra) group according to the random number table,with 34 cases in each group.Patients in the three groups received 4-week tuina treatment with the corresponding acupoint respectively.The blood pressure was recorded by benchtop mercury sphygmomanometer before tuina,immediately after tuina treatment,30 min and 60 min after tuina treatment with the patient in a supine position in a quiet treatment room.The total effective rate was observed.Results:The systolic and diastolic blood pressures of the three groups all decreased after treatment (all P＜0.05).The decrease of systolic and diastolic blood pressure at different time points after treatment in the Qiaogong (Extra) group and the Taichong (LR 3) group were better than those in the Neiguan (PC 6) group (all P＜0.05).Qiaogong (Extra) group had the highest total effective rate though there was no statistical difference in the total effective rate among the three groups (P＞0.05).Conclusion:Treating primary hypertension due to liver-fire flaming-up with tuina at Taichong (LR 3),Neiguan (PC 6) and Qiaogong (Extra) can reduce systolic and diastolic blood pressure respectively,among which Qiaogong (Extra) has the highest total effective rate.

Objective The aim of this study was to investigate the diagnostic value of the intravoxel incoherent motion (IVIM) for discriminating nonmetastatic from metastatic mediastinal lymph nodes in lung cancer.Methods IVIM was performed preoperatively on 66 patients with lung cancer during October 2015 to June 2016 in Capital Medical University Affiliated Beijing Chaoyang Hospital.Preoperative examination including the chest MRI scan,chest CT,head MRI,bone scan-ning and the cardiopulmonary function.None of the patients was undergone any kind of treatment about the cancer before the examinations,the neoadjuvant chemotherapy or radiation therapy,immunotherapy and gene targeted therapy were included.Measured the short axis diameter and the IVIM parameters of the mediastinal lymph nodes,apparent diffusion coefficient(ADC),diffusion coefficient(D),pseudo-diffusion coefficient(D *),and perfusion fraction(f).All the patients underwent the lobectomy or wedge resection and lymph node dissection or systematic sampling.By comparing the IVIM parameters of the nonmetastatic and metastatic mediastinal lymph nodes according to the pathological examination,draw the ROC curves to find the best cutoff value for diagnosis.And 42 cases were used to comparing the value of the MRI and CT in differential diagnosis.Results MRI measured 184 groups mediastinal lymph nodes,including 164 groups without metastasis,20 groups with metastasis.The ADC,D,D *,f values and short axis diameter of the nonmetastatic lymph nodes(n =164) were(2.880 ± 0.785) × 10-3 mm2/s,(0.670 ± 0.179) × 10-3 mm2/s,(0.383 ± 0.123) × 10-3 mm2/s,0.422 ± 0.119,(6.546 ± 1.932) mm,respectively,and (1.897 ±0.657) × 10-3 mm2/s,(0.472 ±0.210) × 10-3 mm2/s,(0.354 ±0.130) × 10-3 mm2/s,0.412 ±0.090,(7.510 ± 2.773) mm respectively for the metastatic lymph nodes (n =20).The ADC and D value of the nonmetastatic lymph nodes were significantly higher than the metastatic lymph nodes(P ＜0.01).While the other paraneters(D *,f,and short axis diameter) between the two groups did not show significantly different.Optimal cutoff values(area under the curve,sensitivity,and specificity) for distinguishing metastatic from nonmetastatic lymph nodes were as follows:ADC =1.890 × 10-3 mm2/s (0.871,92.7％,80.0％);and D =0.648 × 10-3mm2/s(0.740,70.0％,84.1％).Conclusion IVIM is useful to distinguish metastatic from nonmetastatic lymph nodes in lung cancer.The ADC and the D values are significant higher in metastatic lymph nodes,which more sensitive than the other parameters(D *,f,and short axis diameter).As a result,IVIM can be used in the N-stage diagnosis of lung cancer.

OBJECTIVE:To investigate the improvement effect of Prostatitis capsule on chronic non-bacterial prostatitis(CNP) model rats. METHODS:60 rats were randomly divided into sham operation group (distilled water),model group (distilled wa-ter),Pule'an tablet group(positive control,2 g/kg)and Prostatitis capsule high-dose,medium-dose,low-dose groups(16,8,4 g/kg). Except for sham operation group,other 5 groups were injected Xiaozhiling injection 0.2 mL to reduce CNP model. After 7 d of modeling,they received related medicines,ig,once a day,for 45 d. After 24 h of last administration,prostate lesions were ob-served by eyes and wet quality was weighed. White blood cell(WBC)count and lecithin body(SPL)count were conducted under microscope,and prostate tissue slices were pathologically observed. RESULTS:Compared with sham operation group,prostate showed gray nodules,adhesion in glands and surrounding tissue;wet quality of prostate and WBC,SPL count in prostate tissue were significantly increased(P<0.01);under microscope,there were significant congestion,edema and a variety of inflammatory cell infiltration in prostate interstitial. Compared with model group,gray nodules in prostate in Pule'an tablet group and Prostatitis capsule group were reduced,as well as adhesion degree in prostate and surrounding tissue;wet quality of prostate and WBC,SPL count in prostate tissue were significantly decreased(P<0.01);pathological changes had improved to varying degrees under micro-scope,especially the changes in Prostatitis capsule high-dose group,and prostate tissue only showed mild congestion,edema and little inflammatory cell infiltration. CONCLUSIONS:Prostatitis capsule has a certain improvement effect on CNP model rats.

Objective To investigate whether there is an inhibition of the human lung cancer cell line A549 induced by the culture supernatant of Toxoplasma gondii in vitro and the mechanism of the inhibition. Methods A549 cells 5 x 10~4mL~(-1) were cultured and harvested. The cells were treated for different hours with different concentrations of Toxoplasma gondii culture supernatant (the concentrations of tachyzoites were 4×10~7mL~(-1), 8 × 10~7mL~(-1), 16 ×10~7mL~(-1) respectively). Growth inhibition rate was measured with the MTT method; Cell cycle was checked with flow cytometer. Western blot was used to detect the level of cyclinBl and cdc2 of cells. Results The culture supernatants of Toxoplasma gondii inhibited proliferation of A549 cells in a time-dose dependent manner. Cell cycle was significantly stopped at G_2/M phase by the culture supernatants with FCM technology. The culture supernatant of Toxoplasma gondii reduced the expressions of gene cyclinBl and cdc2 of A549 cells. Conclusion The culture supernatant of Toxoplasma gondii may inhibit A549 cell and arrest the cell cycle of A549 cells mainly by regulating the expression of gene cyclinBl and cdc2.

Objective To investigate genotypes and antibiotic resistance of Escherichia coli producing plasmid-mediated AmpC ?-lactamase in Anhui province.Methods A total of 407 clinical isolates of nonrepeated Escherichia coli were collected from different cities in Anhui province.AmpC ?-lactamase producing isolates were identified by cefoxitin three-dimensional test and antibiotic susceptibility was identified by agar dilution test.Plasmid extraction,PCR amplication of corresponding group was performed, followed by sequencing.Results The positive rate of cefoxitin three-dimensional test was 8.1% (33/407), and the prevalence of plasmid-mediated AmpC ?-lactamase was 3.0% (12/407).bla_(CMY-2) gene,bla_(DHA-1) gene and bla_(ACT-2) gene were identified by PCR amplification and confirmed by sequencing in 5 strains,4 strains and 2 strains,respectively.A new CMY genotype was identified,with its sequence revealed 97% identity to the deduced amino acid sequence with previous CMY-2.This is also the first report on ACT-2 genotype in China.The susceptibility test showed that all strains were resistant to cephamycins and piperacillin,and susceptible to imipenem.Two strains of Escherichia coli producing DHA-1 were resistant to fourth-generation cephalosporin.Conclusions CMY-2,DHA-1 and ACT-2 are the most common genotypes in plasmid-mediated AmpC ?-lactamase produced by clinical Escherichia coli isolates in Anhui province. Carbapenems could be the first choice for the treatment of infection caused by AmpC ?-lactamase producers.

Objective: To determine the optimal manipulation parameters in Liu's back tuina therapy for remission-stage cough variant asthma (CVA) in kids. Methods: A 5-factor 3-level L18(37) orthogonal design was adopted. The experimental factors and levels were selected: A, the number of times of Rou-kneading Feishu (BL 13); B, the frequency of Rou-kneading Feishu (BL 13); C, the number of times of Tui-pushing in a '介'-like pattern; D, the frequency of Tui-pushing in a '介'-like pattern; E, the intensity of red color after Ca-scrubbing Feishu (BL 13) with salt. A1, A2 and A3 stood for 10 times, 20 times and 30 times, respectively; B1, B2 and B3 stood for 200 times/min, 240 times/min and 280 times/min, respectively; C1, C2 and C3 stood for 50 times, 75 times and 100 times, respectively; D1, D2 and D3 stood for 150 times/min, 175 times/min and 200 times/min, respectively; E1, E2 and E3 stood for pinkish, bright red and dark red, respectively. A total of 108 kids with CVA in remission stage were divided into 18 groups using the random number table method, with 6 cases in each group. Changes in the cough score and fractional exhaled nitric oxide (FENO) level were observed after 15-day treatment. Results: The cough score and FENO level changed significantly in every group after treatment (all P<0.01). By the effect in improving cough score, the factors were listed as D, B, A, C and E in descending order; the most optimal manipulation parameter combination was group 17 (A3B2C1D3E1); the second optimal parameter combinations were group 7 (A3B1C2D1E3), group 13 (A2B1C2D3E1) and group 14 (A2B2C3D1E2). Regarding the effect in down-regulating the level of FENO, the factors were listed as C, A, E, B and D in descending order; the most optimal manipulation parameter combination was group 13 (A2B1C2D3E1); the second optimal parameter combinations were group 18 (A3B3C2D1E2), group 16 (A3B1C3D2E3) and group 14 (A2B2C3D1E2).Conclusion: Two most effective manipulation parameter combinations were selected out of 18 different parameter combinations in Liu's back tuina therapy for remission-stage CVA in kids. Doctors can choose an appropriate manipulation based on the symptom features of the disease.

As the integration of human parasitology and medical microbiology curriculum, pathogen biology, although constructed and developed about 20-years, didn't realize the true integration of the two disciplines. Beyond that, it was also faced with numerous difficulties such severe compression of human par-asitology class, lack of teaching materials to achieve the true meaning of integration, difficulty to cultivate teachers and so on. The organ-system based learning (OBL) curriculum model may provide new strategies for the dilemma, to be resolved through the following channels: Rearranging the curriculum and teaching materials based on the classification of pathogenic organism parasitic or invasive organs; Corresponding training in microbiology and parasitology teaching by teachers continuous realization, while highlighting the professional teaching level of highly qualified teachers in both courses.
