Effects of traditional Chinese medicine salvianolate combined with alprostadil and reduced glutathione on delay of progression in patients with acute kidney injury has been confirmed, but the role of this combination therapy on the progression of chronic renal failure is uncertain.

Objective To investigate the effects of Sini decoction on function of hypothalamic-pituitary-adrenal axis in patients with sepsis.Methods A prospective single-blind randomized controlled trial was conducted.60 septic patients were divided into three groups with the method of random number table,20 cases in the control group,20 in the Chinese herb group,and 20 in corticoid group.All of them received routine treatment.Patients in Chinese herb group were given Sini decoction in addition (decoction of monkshood 15 g,dried ginger 15 g,honey-fried licorice 10 g) 100 mL/d orally or by nasal feeding,while patients in corticoid group were given hydrocortisone 200 mg/d intravenously instead,both for 7 days.Before the treatment,3 days and 14 days after treatment,blood was collected to determine the levels of adrenocorticotropic hormone (ACTH) and cortisol,and the result of ACTH stimulating test was observed.At the same time,acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score was recorded,and 3-day shock recovery rate and 28-day death rate were also compared among these groups.Results None of the three groups showed different result in ACTH stimulating test (x2=1.101,P=0.605).ACTH in three groups was gradually decreased.Compared with that before treatment,ACTH in Chinese herb group and corticoid groups began to decrease obviously on day 3 (ng/L:29.90 ± 3.31 vs.33.10 ±.3.31,28.20 ±.2.45 vs.33.30 ± 3.84,both P＜0.01),while in control group declined ACTH appeared later (on day 14) compared with before treatment (ng/L:29.40 ±5.63 vs.33.50 ±4.89,P＜0.05).No obvious difference in ACTH level was showed between the Chinese herb group and the cortical group (both P＞0.05).Cortisol level in both Chinese herb and cortical groups showed a raise-fall biphase trend while there was no change in the control.The cortical levels on day 3 in Chinese herb and cortical groups were much higher than that before treatment (μg/L:343.04 ± 31.20 vs.294.70 ±42.10,331.25 ±42.80 vs.280.36 ± 38.10,both P＜0.01) and that of control group (μg/L:291.61 ± 41.50,both P＜0.01),though no significant statistical difference was observed between two groups (both P＞0.05).APACHE Ⅱ score on day 14 in control,Chinese herb and cortical groups was significantly lower than that before treatment (16.8 ± 5.1 vs.20.1 ± 4.3,13.4 ± 3.2 vs.18.3 ± 3.8,15.1 ± 2.5 vs.19.5 ± 4.0,all P＜0.01),and the score was much lower in Chinese herb group comparing with that of control group (P＜0.05).No statistical difference was observed among control,Chinese herb and cortical groups in lowering 28-day death rate [35.0％ (7/20),25.0％ (5/20),20.0％ (4/20)] and improving 3-day shock recovery rate [40.0％ (8/20),70.0％ (14/20),60.0％ (12/20),all P＞0.05].Conclusions Sini decoction could elevate cortisol while lower ACTH at the early stage of sepsis.Sini decoction could also effectively improve symptoms and hypothalamic-pituitary-adrenal axis function in septic patients without affecting death rate.

Objective To evaluate the imaging diagnosis of anomalous origin of coronary artery from the pulmonary artery(ACAPA).Methods A total of 11 cases with ACAPA were included in the present study.Chest films,echocardiography,cardioangiography,and electron beam computed tomography (EBCT) were employed as diagnostic modalities.Macroscopic anatomy at operation was referred. Results Ten cases were classified as anomalous origin of left coronary artery from the pulmonary artery(ALCAPA) and 1 case as anomalous origin of right coronary artery from the pulmonary artery(ARCAPA).They could not be diagnosed by chest films,but could be diagnosed by echocardiography in 3 cases,by EBCT in 1 case,and by cardioangiography in all cases.In ALCAPA,cardioangiography showed that the left coronary arteries arising from the posterior sinus or posterior wall of the pulmonary artery were perfused retrogradely via the collaterals from the dilated right coronary artery.In ARCAPA,the right coronary artery originated from the right sinus of the pulmonary artery.Gross anatomy at operation showed that the sites of the anomalous origins were the same as that of cardioangiography.Ischemic fibrosis of the anterior papillary muscles,mitral valve annulus enlargement,and prolapse of mitral valve,which led to mitral valve insufficiency,were found in 3 cases.Conclusion Chest film has limitation in the diagnosis and echocardiography should be further improved.Cardioangiography remains the “gold standard” of the preoperative diagnosis.

Objective To investigate the relationship between Wnt5a gene and E-cadherin or vimentin gene in breast cancer cell line MCF-7. Methods RT-PCR was used to detect the mRNA expression of Wnt5a, E-cadherin and vimentin in breast cancer MCF-7 cells and the normal human mammary epithelial cell line MCF-10A, respectively, and their correlation was analyzed. Results The mRNA expression levels of Wnt5a and E-cadherin in cell line MCF-7 were significantly lower than those in cell line MCF-10A [(16.93± 2.97)%vs. (27.47±2.76) %, (12.97±1.35) % vs. (20.43±2.60) %, both P<0.05]. The mRNA expression level of vimentin in cell line MCF-7 was significantly higher than that in cell line MCF-10A [(16.53±0.85)%(6.33± 2.08) %, P<0.05 ]. In cell line MCF-7, the expression of Wnt5a was positively related to E-cadherin (г=0.997, P<0.05), but it was negatively related to vimentin (г=-0.998, P<0.05). Conclusions The expression of Wnt5a in human breast cancer cell line MCF-7 is significantly lower than that in cell line MCF-10A, which indicates that Wnt5a is a cancer suppressor gene in breast cancer. The expression of Wnt5a in cell line MCF-7 is positively related with E-cadherin, and it is negatively related with vimentin. Wnt5a may cause invasion and metastasis of breast cancer cell through the breast epithelial mesenchymal transitions.

Objective Comparison of the levator ani muscles in three-dimensional (3D) MRI-based models in women with and without pelvic organ prolapse at rest to analyze the morphological characteristics of levator ani muscles in women with POP. Methods Twenty-five women with POP and 22 women with normal pelvic support were selected from Nanfang Hospital of Southern Medical University. Axial, sagittal, and coronal T2-weighted pelvic magnetic resonance scans were obtained with the women in the supine position.The 3D models were reconstructed from the source images. Morphological changes was compared within the two groups of levator ani muscles, and the 3D models were measured to determine the levator ani muscle volume (LVOL), levator plate angle (LPA), levator hiatus width (LH-W) and length (LH-L), distance between symphysis and levator sling muscle (LSG). Results There were no puborectalis avulsions in control, in POP, 3 cases of avulsions just in left, 3 cases of avulsions just in right, 7 cases in bilateral. The shape of iliococcygeus were all dome-shaped in control, 11 cases were U-shaped and 14 cases were dome-shaped in POP. The shape of levator hiatus were 7 cases of U-shape, 12 cases of V-shape, 3 cases of irregular in control; 5 cases of U-shape, 4 cases of V-shape, 16 cases of irregular in POP. POP versus control: LH-L: (68.0 ± 8.9) versus (61.6 ± 7.2) mm (P<0.05); LH-W: (41.4 ± 3.9) versus (38.0 ± 3.2) mm (P<0.05); LSG-L: (29.6 ± 7.4) versus (24.6 ± 3.7) mm (P<0.05); LSG-R: (28.4 ± 6.8) versus (23.9 ± 3.2) mm (P<0.05); LPA: (51.0 ± 11.3)° versus (40.6 ± 6.3)° (P<0.05); LVOL: (23.7 ± 5.8) versus (24.6 ± 5.0) cm3 (P>0.05). Conclusions It is possible to assess the morphologic changes of levator ani by using 3D MRI models objectively, our 3D data demonstrate larger in LVOL, LPA, LH-W, LH-L, LSG, and the changes in shape. It is helpful to diagnose and assess the specific situation of patients POP in clinic.

Objective To explore the value of pelvic CT angiography(CTA)digital three-dimensional reconstruction model(abbreviated as"three-dimensional model")in the diagnosis of female pelvic mass.Methods A total of 98 patients with pelvic mass who were hospitalized and operated in Xi'an People's Hos-pital(Xi'an Fourth Hospital)from January 2021 to April 2023 were selected.All patients underwent B-ultra-sound and CTA examination before operation,and the original data of CTA were collected.The digital three-dimensional model of pelvic mass was established by three-dimensional reconstruction software,and the source of pelvic mass was judged according to the blood supply of pelvic mass.Taking postoperative pathological di-agnosis as the gold standard,the coincidence rate between different preoperative diagnosis methods(B-ultra-sound,CTA examination and three-dimensional model)was compared.The receiver operating characteristic(ROC)curve was plotted to evaluate the efficacy of different preoperative diagnostic methods in judging the ovarian origin of pelvic tumors.Results A total of 130 pelvic masses were included in 98 patients,and the average maximum diameter of the mass was(71.61±3.03)mm,including 83 ovarian masses and 47 non-ovarian masses.Taking postoperative pathological diagnosis as the gold standard,the diagnostic coincidence rate of the preoperative three-dimensional model was 72.31％,which was higher than that of B-ultrasound(58.46％)and CTA(52.31％),and the differences were statistically significant(P＜0.001).The sensitivity,specificity,positive predictive value,negative predictive value,accuracy,Kappa value,and area under the ROC curve were 79.51％,91.49％,94.29％,71.67％,83.85％,0.67 and 0.855,respectively,when the three-dimensional model showed that the blood supply of the mass originated from ovarian artery or uterine artery-ovarian branch.Conclusion The three-dimensional model of pelvic CTA can directly display the blood supply source,characteristics of mass,and the relationship between mass and adjacent organs,which can guide the clinical treatment.It has certain clinical value to judge the ovarian origin of pelvic mass by using ovarian artery and uterine artery-ovarian branch.
