Objective To investigate the clinical value of 99mTc-MDP SPECT/CT whole body bone imaging in the diagnosis of bone metastasis of prostate cancer. Methods A total of 107 cases with prostate cancer were di-agnosed by SPECT whole body bone imaging from January 2013 to November 2016. SPECT/CT imaging of some ab-normal density collective focus found in whole body bone imaging were further carried out. Six months later ,whole body bone imaging and SPECT/CT were made again for review. In all diagnosis above ,99mTc-MDP were selected as bone imaging agent. According to the results of follow-up visit clinical and imaging diagnosis ,diagnostic perfor-mance indicators of whole body bone imaging and SPECT/CT were calculated. Results The different part of whole body bone imaging and SPECT/CT in the diagnosis of bone metastases was statistically significant(x2 = 23.000, P < 0.001). The diagnosis specificity and coincidence rate of SPECT/CT for bone metastasis were 100.0% and 98.1% respectively and they were significantly higher than those of whole body bone imaging(65.0% and 80.4%respectively). The differences were statistically significant(P < 0.05). After SPECT/CT diagnosis,a total of 193 undetermined lesions were found and 83 lesions of these were final diagnosed of bone metastases. Pelvic lesions were most in bone metastases ,accounting for 50.6%. Conclusion Whole body bone imaging can effectively determine the undetermined lesions , further SPECT/CT can significantly improve the diagnostic accuracy of prostate cancer bone metastasis.

Results The desired DNA could be acquired from tissues of human muscle by RT-PCR using special primers, the acquired cDNA fragment could be cloned into vector of pGEM-3zf(-) and sequenced. The GLUT4 cDNA sequence was highly conserved. GLUT4 cDNA could be expressed in E.coli, too. Conclusion The entire GLUT4 cDNA can be acquired from human muscular tissue by RT-PCR, and it can be expressed in E.coli.

Objective: To estimate the efficacy and safety of flexible ureteroscopy combined with holmium laser lithotripsy in the treatment of upper urinary tract calculi in infants aged 3 years old and below. Methods: From January 2016 to March 2019, the cases of infants aged 3 years old and below who were treated with flexible ureteroscopy combined with holmium laser lithotripsy for upper urinary tract calculi in Department of Urology, Shanghai Children's Medical Center, Shanghai Jiao Tong University School of Medicine were collected. The double J (DJ) stents were placed in the cases for 0.5-3 months, followed by flexible ureteroscopy combined with holmium laser lithotripsy after urinary tract infection was controlled. OLYMPUS flexible ureteroscope and 200 μm holmium laser fiber were used in the operation. Holmium laser power was 20-30 Hz/0.5-1.0 J according to the size and hardness of the stones, and then DJ stent was retained after retraction of the ureteroscope to finish the operation. Results: A total of 32 infants aged 3 and below with upper urinary tract stones were included in the study, including 21 males and 11 females, and the median age was 26 months (7-36 months). All 32 cases were successfully treated with flexible ureteroscopy combined with holmium laser lithotripsy. Among them calculi in 22 cases were removed after one operation, and the calculi-free rate after one operation was 68.8%. The median duration of operation was 53 min (15-110 min); the median hospitalization after operation was 3 d (2-12 d); the median days of DJ stent removal after operation was 60 d (18-100 d). Urinary tract infection occurred in 4 cases, and high fever with urinary tract infection occurred in 2 cases. Anti-infection and other symptomatic treatments were given respectively to improve the symptoms. Conclusion: Flexible ureteroscopy combined with holmium laser lithotripsy is effective and safe in the treatment of upper urinary tract calculi in infants, which can be widely used in clinic.

Conclusion: Right heart contrast echocardiography may simply and effectively detect abnormal blood shunt in patients combining pulmonary arterial hypertension and improve the diagnostic accuracy of CHD.

OBJECTIVE: To further probe the mechanisms of herbs for nourishing and smoothing the liver in reversing bile lithogenicity of guinea pig. METHODS: Sixty guinea pigs were divided randomly into control group (fed with normal diet, n=20), model group (fed with lithogenic diet, n=20) and treatment group (fed with lithogenic diet plus herbal medicine, n=20). After four-week feeding, the animals were sacrificed and sampled, the rates of gallstone formation in each group were estimated, and the total bile acid (TBA), total bilirubin (TBIL), conjugated bilirubin (CB), unconjugated bilirubin (UCB), and calcium ion in the bile were determined, and the different bilirubins were analyzed by HPLC. RESULTS: (1) The rate of gallstone formation was 5% in normal group, 81.25% in model group and 31.25% in treatment group (P<0.05). (2) The bile TBIL, CB, UCB and Ca(2+) were higher and the bile TBA was lower significantly in model group than that in the other two groups (P<0.05). (3) HPLC analysis revealed that MCB was higher and DCB was lower significantly in model group (P<0.01), and there were no significant differences of UCB and IPA among the three groups. (4) The percentages of MCB and UCB were much higher and the percentage of DCB was remarkably lower in model group (P<0.05). CONCLUSION: Herbs for nourishing and smoothing the liver can significantly reduce the rate of gallstone formation and has effect of reversing lithogenicity of bile in guinea pigs fed with lithogenic diet.

Objective: To investigate the analgesic substances in the aerial part of Urtica fissa (Urticae Fissae Herba), commonly used for rheumatoid and rheumatism arthritis. Methods: The analgesic constituents were isolated with the active guidance of hot plate and acetic acid writhing models, and identified by comprehensive spectroscopic analysis. Results: Thirteen alkaloids (1–13), two lignans (14, 15), and three amides (16–18) were isolated from the active fractions. Among them, compound 1 was a new alkaloid, and compound 6 was a new natural product. The activity evaluation in vivo indicated that various pyrrole alkaloids (1, 3, 6, and 12) possessed significant analgesic activities, they could significantly inhibit the mice pain response induced by acetic acid and hot plate at the dosage of 2 mg/kg BW. Conclusion: The study revealed that the pyrrole alkaloids played important roles in the analgesic activities of Urticae Fissae Herba.

OBJECTIVETo explore the effects of Guizhi Tang on the inflammatory cytokines in myocardial ischemia and hyperlipidemia rats.

To study the protective effect of Danshen Tongluo capsule on rat hearts in the myocardial infarction (MI) model. After being fed with high fat diets for one month, the SD rats were randomly divided into the sham group and the model group according to the left ventricular ejection fraction (EF). The MI model group was duplicated by ligating coronary artery and then divided into five groups: the model group, the positive control group (model + captopril), the small dose group (model + Danshen Tongluo), the medium dose group (model + Danshen Tongluo) and the high dose group (model + Danshen Tongluo). Four weeks later, changes in myocardium ultra-structure were observed by hemodynamics, cardiac ultrasound and electron microscope. The results showed: (1) All doses of Danshen Tongluo capsule could significantly reduce the left ventricular end diastolic pressure (LVEDP) (P <0.01), increase the maximum internal pressure of the left ventricle (+ dp/dtmax), and lower the drop rate of left ventricular pressure (- dp/dtmax), with statistical significances in medium and high dose groups; (2) The B ultrasound results showed increase in EF and left ventricular shortening fraction (FS) in all dose groups of Danshen Tongluo capsule; (3) The medium dose group showed significant decrease in myocardial infarction index (P <0.01) and injured and fractured myofilament and sarcomere of ischemic myocardium in myocardial ultra-structure; All of Danshen Tongluo capsule-treated groups revealed reduction in myocardial injury and myocardial infraction area. The study preliminarily proves that Danshen Tongluo capsule can improve hemodynamic function, and has a protective effect on myocardial ischemia.
