Professor ZHANG Lei is one of the most renowned doctors in traditional Chinese medicine. He is good at treating miscellaneous disease of internal medicine, and summarizes eight clinical therapy from long-term clinical practice, and cleaning turbidity therapy is one of the most characteristic therapy. Cleaning turbidity therapy is founded under today's improvement of living standards and changes of lifestyle where more and more turbidity syndromes are caused. Qianjin Weijing Decoction is used as main prescription and modified according to different zang-fu where turbidity syndromes are located. On account of cleaning turbidity therapy is one of the eliminating pathogens therapy, strengthening healthy qi must be used according to power of healthy qi, especially healthy qi of spleen and stomach.

Objective To study the CT features of pulmonary non-tuberculous mycobacteria (NTM) disease in patients with acquired immunodeficiency syndrome (AIDS) and explore the different CT appearances between AIDS-NTM and AIDS-TB.Methods CT findings of pulmonary NTM disease in 27 AIDS patients (NTM group) were retrospectively analyzed and compared with that of tuberculosis in 30 AIDS patients (TB group).The results were statistically analyzed using Fisher's exact test.Results CT findings of NTM appeared significantly more than that of TB as follows:high-density nodules (n =18 vs 1,P ＜ 0.01),ground-glass opacities (n =10 vs 0,P ＜ 0.01),fibrotic band (n =17 vs 3,P ＜ 0.01),bronchiectasis (9 vs 2,P =0.012).CT findings of NTM appeared significantly less than that of TB as follows:miliary nodules (0 vs 6,P =0.016),air space consolidations (n =2 vs 11,P ＜ 0.01),pleural effusion (n =1 vs 9,P ＜ 0.01).Conclusion Nodule and fibrotic band companied with bronchiectasis were the main CT manifestations of pulmonary NTM disease in AIDS patients,while air space consolidation companied with pleural effusion and miliary nodules were the predominate CT findings of pulmonary tuberculosis in AIDS patients.

Objective To construct GST/HIF1α fusion protein expression vector and induce its expression in Escherichia coli (E.coli). Methods The coding sequence of hypoxia inducible factor-la (HIF-la) and its deletion fragments were amplified from the plasmid pcD-NA3.1-HIF-la by PCR and inserted into pGEX-4T-2 by BamHI and Not I. The positive recombinanls were identified by restriction endonu-clease digestion and DNA sequencing. Then they were transformed into E.coli BL21, induced by IPTG and identified by SDS-PAGE and Western blot. Results The prokaryotic expression plasmid pGEX-4T-2-HIF-lα and its deletion mutants were successfully constructed and confirmed by enzyme digestion and sequencing. The desired CST/HIF-1α fusion proteins were expressed and confirmed by Western blot. Conclusion The prokaryotic expression plasmid of HIF-la and its deletion mutants were successfully constructed and the expression of fu-sion proteins was confirmed. This study provides the basis for the further research on purifying HIF-la protein and the biological function of HIF-lα.

Objective To observe the clinical, mammographic and sonographic features of pure invasive lobular breast carcinoma (ILC), and to explore the value of combined imaging assessment of ILC. Methods Sonographic appearances of 55 patients of ILC were retrospectively reviewed in correlation with mammographic, pathologic and clinical findings, and the causes of false negative were analyzed. Results The main features found in clinical examination were mass (96.15%) and thickening in the size of breast (3.85%). The main mammographic features were spiculated or ill-defined mass (65.38%) and architectural distortion (23.08%). The most common sonographic patterns were mass (98.00%) and distortion (2.00%). The accuracy for detecting ILC of clinical examination, mammography and ultrasonography was 94.55%, 83.87% and 98.04%, respectively, while combining the three modalities, the detection rate increased to 100%. Conclusion Sonography has higher accuracy than mammography in detecting ILC. Combining clinical examination, mammography and ultrasonography can increase the pre-operative diagnostic accuracy of ILC.

Objective To explore the feasibility of anti-85B and ESAT-6 monoclonal antibodies targeted contrast agent of CT by the murine acute tuberculosis animal model.Methods Preparation the targeted contrast agent of computed tomography by iodine atoms coupled with anti-85B and ESAT-6 murine monoclonal antibodies after purified.Calculate the label rate and the quality of 127Ⅰ of the targeted contrast agent solution,and dilute the contrast agent solution to the required concentration (5μg I/ml) to spare.There were twenty mice of acute tuberculosis animal model,which were divided into four groups by completely randomized digital table and each group was five animals.According to the different antibody named as 85B group and ESAT-6 group of targeted contrast agent,common contrast agent and blank control separately.The common contrast agent group was injected with diluents of iohexol,which was diluted into the same concentration with the targeted contrast agent.The control group was injected with antibody diluents pH 7.4 Phosphate Buffered Saline (PBS).All the animals were scanned before and after injection the contrast agent in different time,such as immediate,6 hours,12 hours and 24 hours.Observe the display and changes of the murine tuberculosis lesions,and measurement the CT value,which was regarded as evaluating mark.Enhancement ratio was also calculated.Two sample mean differences with t test and the multiple sample mean differences with ANOVA.Results The volume of anti-85B contrast agent solution was 2.52 ml,and the quality of antibody and 127Ⅰ were range from 210 to 255 μg and 10.5 to 16.6 μg respectively.The volume of anti-ESAT-6 contrast agent solution was 2.93 ml,and the quality of antibody and 127Ⅰ were 147 μg and 20.58 μg respectively.The lesions of the control group showed no visible density changes before and after injection of PBS.The CT value of the lung lesions in the targeted contrast agent group were gradually increased with time,and the lesion showed visible enhancement after the contrast injection twelve hours(t12),and also remained visible enhancement after injection twenty-four hours(t24)[85B group t12 =(-125.04 ± 13.58) HU,t24 =(-117.37 ± 12.28) HU and ESAT-6 group t12 =(-122.14 ± 19.01) HU,t24 =(-114.23 ± 17.08) HU],which is significant difference compared to the common contrast agent [t (85B-24 h) =4.05,t (ESAT-6-24 h) =6.39,P ＜ 0.05].Conclusions The targeted property of anti-85B and ESAT-6 murine monoclonal antibody contrast agent of CT had been partly proved by the acute tuberculosis animal model.Also provided an experimental basis for further study of tuberculosis targeted contrast agent.

Objective To explore the mechanism of intrathoracic pressure(ITP) influncing cardiac function and facilitate noninvasive determination of ventricular pressure theoretically.Methods With Valsalva and Mueller maneuver,two-dimension images of standard long axis views and the cross-sectional views were recorded in 20 volunteers,aged from 18 to 45 years,at the specific ITP levels(including-20 mmHg、-10 mmHg、0 mmHg、+ 10 mmHg and + 20 mmHg).The subjects were instructed to mantain for at least 10 s,and three successive measurements were recorded and averaged.The stroke volume(SV) and radius of curvature(R) were obtained from further off-line analysis.Results With the ITP maintaining at -20 mmHg,-10 mmHg,0 mmHg(end expiration),+ 10 mmHg and + 20 mmHg respectively,the corresponding radiuses of curvature were (2.35 ±0.24)cm,(2.25 ± 0.23)cm,(2.14 ± 0.21)cm,(2.02 ± 0.21) cm,(1.93 ± 0.19) cm,there were statistically significances between two groups (P =0.006,0.031,0.005 and ＜0.001,respectively].When the ITP were at 0 mmHg(end expiration),+ 10 mmHg and + 20 mmHg,the stroke volume were (71.54±8.81)ml,(73.20±9.52)ml and (78.81± 14.61)ml (P =0.674,0.135).When the intrathoracic pressure decreased from 0 mmHg to-20 mmHg,the stroke volume were (78.81±14.61)ml,(68.28 ±9.28)ml and (59.69±7.52)ml(P =0.029,0.037).Conclusions The ITP has different effects on the two ventricles,and subsequently generates a pressure gradient across the IVS which can alter its shape and position at end-diastole.With the IVS shifting,the preload and filling function of left ventricle gets changed acorrding to the Frank Starling principle.

Objective To investigate the effect of early nursing intervention on severe complication of radical cystectomy and orthotopic ileal neobladder.Methods A total of 30 patients undergoing radical cystectomy with orthotopic ileal neobladder were randomly divided into the intervention group and the control group with 15 cases in each group,the control group received routine nursing,while the intervention group received psychological counseling,health education,sufficient preoperative preparation,postoperative strict tube care,nutritional support according to the serious complications after operation.The postoperative complications,indwelling time of tubes,hospitalization days between two groups were compared.Results Serious complications rate after surgery of the intervention group was lower than that in the control group.The indwelling time of tubes,length of stay in the intervention group were less than those of the control group,the two groups had significant difference.Conclusions Early predictive nursing intervention can reduce compli-cations rate after radical cystectomy and ileal neobladder,shorten the hospitalization time and improve the success rate of operation.

Objective To investigate the effect of ultrashort wave therapy on edema and inflammatory reaction after spinal cord injury (SCI) in rats. Methods 56 Sprague-Dawley rats were divided into sham-operated group (n=8), model group (n=24) and ultrashort wave group (n=24). The model was established with Allen's method. The sham-operated group was exposed endorhachis without hit. The ultra-short wave group was exposed to ultrashort wave radiation 7 minutes, once a day, 24 hours after modeling until the animals were sacrificed. Locomotors functional recovery was assessed every week post operation period by BBB score. Immunohistochemical staining was per-formed to observe the expression of the aquaporin-4(AQP-4) and ED-1. Results The BBB scores increased in the model group and the ultra-short wave group after treatment, and was higher in the ultrashort wave group than in the model group from 1 week after treatment (t>3.368, P<0.01). The expressions of AQP-4 and ED-1 were higher in the model group and ultrashort wave group than in the sham-operated group, and decreased as time went on. They were lower in the ultrashort wave group than in the model group(t>3.156, t>4.466, P<0.05). Conclu-sion Ultrashort wave therapy can alleviate the edema after SCI, reduce the activation and infiltration of inflammatory cells, and promote the recovery of neurological function.
