Chinese Journal of Medical Imaging Technology 2020;36(7):1105-1108
Portal hypertension (PH) is a major complication of liver cirrhosis,manifested as ascites, esophageal-gastric fundal varices bleeding and hepatic encephalopathy. Hepatic venous pressure gradient (HVPG) is considered the gold standard in diagnosis of PH, but is invasive. Ultrasound elastography has been widely used in clinical practice, especially in evaluation of liver fibrosis staging and PH in patients with advanced chronic liver disease. The application progresses of ultrasound elastography in predicting PH and its complications were reviewed in this article.

Objective To analyze the incidence of coronary myocardial bridge (MB) of the Uyghur and Han peoples with 64-slice CT. Methods A total of 1350 patients with suspected of coronary disease or other diseases underwent coronary angiography with 64-slice CT, among them 341 patients were diagnosed as MB, including 260 Han people, 70 Uyghur people, 7 Muslim people and 4 people of Kazak ethnic minority group. The incidence of MB of the Uyghur and Han people was calculated respectively; incidence of MB in proximal, middle and distal segment of left anterior descending (LAD), the first diagonal branch (D1), the second diagonal branch (D2), obtuse marginal (OM), left circumflex (LCX) and right coronary artery (RCA) between two races were compared with Chi-Square test. Results Totally 341 patients had 439 MB, 332 in Han people, 92 in Uyghur people, 9 in Muslim people and 6 in Kazak ethnic minority group with 64-slice CT. There was no statistical significance of MB incidence between the Uyghur and Han people in coronary artery (P>0.05), including the proximal, middle and distal segment of LAD. Conclusion The 64-slice CT can effectively detect MB with a high special resolution. There is no statistical significance of MB incidence between the Uyghur and the Han people in each coronary artery.

OBJECTIVETo examine the protective effects of Astragalus injection (AI) on cisplatin (DDP)-induced nephrotoxicity and to explore the mechanism of its nephroprotection.
METHODThe S180-bearing model was established, and fifty mice were randomly divided into five groups: control mice, DDP-injected mice (3.5 mg x kg(-1)) and AI-pretreated mice (12, 8, 4 g x kg(-1)). Tumor inhibition rate, renal functions, histological findings were investigated. The apoptotic cells were counted by TUNEL and the presence of Bax, Bcl-2 in renal tissues was determined by immunohistochemistry.
RESULTSAdministration of DDP or DDP plus AI showed promising anti-tumor activities as compared with control group. Interestingly, a combination of DDP and AI (12, 8 g x kg(-1)) led to enhanced tumor growth inhibition as compared with DDP alone (all P < 0.05). Compared with that from control, the number of TUNEL-positive cells and the Bax/Bcl-2 ratio was increased significantly in the kidneys of DDP treated mice (P < 0.05). High-dose AI pretreatment significantly reduced the elevated number of TUNEL-positive cells and the Bax/Bcl-2 ratio (P < 0.05), and it showed a superior nephroprotective effect than any other dose. AI significantly also decreased both the damage to renal function and histological pathology.
CONCLUSIONPre-treatment with AI attenuates cisplatin-induced nephrotoxicity without compromising the anti-tumor efficacy of DDP, which might be involved in regulating the Bax and Bcl-2 expression.

Chronic obstructive pulmonary disease (COPD) is characterized by excess in nature and deficiency in superficiality. For COPD patients, the deficiency of lung and kidney is the basis for production of the latent toxin, and repeated exogenous infection is the main factor for the latent toxin to enter the lung. The key pathogenesis of stable COPD is the entry of latent toxin into the lung and the injury of lung and collaterals. Therefore, tonifying lung and kidney, removing toxins and dredging collaterals are the core treatment methods for COPD in stable period. Bufei Decoction is with good efficacy in the treatment of COPD in stable period, which can not only tonify lung and kidney to consolidate, but also dredging collaterals to remove toxins. Based on the pathogenesis of "latent toxin entering lung", the relevant mechanisms of Bufei Decoction in treating stable COPD were further understood and explored, in order to benefit clinical practice.

Objective:To explore the value of liver stiffness and spleen stiffness measured by two-dimensional shear wave elastography (2D-SWE) in predicting high-risk varices (HRV) with compensated cirrhosis patients.Methods:Seventy patients with compensated cirrhosis who attended the First Hospital of Lanzhou University from November 2019 to April 2022 were recruited. All patients underwent examinations of liver stiffness measurement (LSM) and spleen stiffness measurement (SSM) by 2D-SWE. Binary logistic regression was used to analyze the risk factors affecting the occurrence of HRV. The diagnostic performances of LSM, liver stiffness (by 2D-SWE)-spleen length-to-platelet (LSPS) score, and SSM in predicting HRV were compared.Results:SSM was not technically feasible in 6/70 (8.6%) patients due to small volume of spleen.Among 64 patients with compensated cirrhosis, 30/64 (46.9%) were HRV. Binary multivariate Logistic regression analysis showed that SSM and platelet counts were independent influencing factors for predicting HRV, with OR values of 1.126 ( P=0.006) and 0.971 ( P=0.039), respectively. The area under the receiver operating characteristic curve (AUC) of LSM, LSPS score, and SSM were 0.660, 0.828 and 0.858, respectively. The AUCs of SSM and LSPS score were significantly higher than that of LSM ( P<0.05), but there was no statistical difference between SSM and LSPS score ( P=0.608). Conclusions:LSM and SSM measured by 2D-SWE have high success rate. SSM and LSPS score have high value in predicting HRV in patients with compensated cirrhosis, and the diagnostic performances of the above two methods are significantly higher than that of LSM.

Observation indicators: (1) clinical charac-teristics of cirrhotic portal hypertension patients; (2) overall prevention and treatment of EVB in cirrhotic portal hypertension patients; (3) prevention and treatment of EVB in cirrhotic portal hypertension patients from different grade hospitals. Measurement data with normal distribution were represented as Mean± SD. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. Results:(1) Clinical characteristics of cirrhotic portal hypertension patients: of 820 cirrhotic portal hypertension patients, 271 cases were in compensated stage and 549 cases were in decompensated stage. Of the 271 cases in compensated stage, there were 183 maels and 88 females, aged (53±12)years. There were 185 Han people, 85 Hui people and 1 case of other ethic group. The etiological data of liver cirrhosis showed 211 cases of viral hepatitis B, 4 cases of alcoholic liver disease, 8 cases of viral hepatitis C, and 48 cases of other etiology. There were 235 cases of Child-Pugh grade A and 36 cases lack of data. Of the 549 cases in decompensated stage, there were 355 males and 194 females, aged (57±14) years. There were 373 Han people, 174 Hui people and 2 cases of other ethic group. The etiological data of liver cirrhosis showed 392 cases of viral hepatitis B, 33 cases of alcoholic liver disease, 10 cases of viral hepatitis C, and 114 cases of other etiology. There were 80 cases of Child-Pugh grade A, 289 cases of grade B, 170 cases of grade C and 10 cases lack of data. (2) Overall prevention and treatment of EVB in cirrhotic portal hypertension patients: of 271 patients in compensated stage, 38 cases received non-selective β-blocker (NSBB) therapy, 16 cases received endoscopic treatment, 6 cases received interventional therapy. Of 549 patients in decompensated stage, 68 cases received NSBB therapy, 46 cases received endoscopic treatment, 28 cases received interventional therapy.

Ninety cases came from secondary hospitals, of which 10 cases received NSBB therapy, 1 cases received endoscopic treatment. There was no significant difference in NSBB for prevention of EVB between tertiary and secondary hospitals ( χ2=0.947, P>0.05), while there was a significant difference in endoscopic treatment for prevention of EVB between tertiary and secondary hospitals ( χ2=5.572, P<0.05). Of 549 patients in decompensated stage, 309 cases came from tertiary hospitals, of which 22 cases received NSBB therapy, 29 cases received endoscopic treatment, 22 cases received interventional therapy. Two hundreds and fourty cases came from secondary hospitals, of which 46 cases received NSBB therapy, 17 cases received endoscopic treatment, 6 cases received interven-tional therapy. There were significant differences in NSBB and interventional therapy for prevention of EVB between tertiary and secondary hospitals ( χ2=18.065, 5.956, P<0.05). Conclusions:The proportion of receiving EUB prevention in cirrhotic portal hypertension in Ningxia is relatively low. For patients with compensated liver cirrhosis, the proportion of NSBB therapy and endoscopic treatment in the secondary hospitals was lower than that in tertiary hospitals. For patients with decompensated liver cirrhosis, the proportion of interventional treatment in secondary hospitals is lower than that of tertiary hospitals, but the proportion of NSBB in secondary hospitals taking is higher than that of tertiary hospitals.
