Purpose To investigate the significance of arterial phase display of right ovarian vein (ROV) for patients with pelvic congestion syndrome (PCS) through multi-slice CT angiography (MSCTA) Materials and Methods Forty-three patients with PCS confirmed clinically who underwent MSCTA were involved in the study. Revascularization was realized via add vessel volume rendering technique and maximum intensity projection (MIP) and the relationships among ROV early development, location of converging vascular, development of LOV and pelvic draining veins were analyzed. Results Out of 43 cases of ROV early development during arterial phase, 21 cases (48.8%) took ROV as draining vein of PCS, among which 17 cases (81.0%) converged into the inferior cava vena. In 19 cases (44.2%), ROV took part in the formation of PCS, all originating from the main right renal vein. Three cases (7.0%) were renal vein-derived PCS, among which two ROV originated from the main right renal vein and one from the branch of the right renal vein. Conclusion According to the imaging features of bilateral ovarian veins and pelvic veins, ROV, as draining veins, is associated with the formation of PCS.

Objective To determine the influencing factors of post-stroke depression by machine learning.Methods Stroke patients' medical records (688 cases eligible) were extracted from record system,including age,gender,pulse manifestation,complexion,tongue quality,fur,Chinese medicine intervention,body mass index (BMI),blood pressure,blood glucose,blood triglyceride,blood total cholesterol,smoking history,drinking history,depression family history,stroke lesion site in imaging,as well as the final depression judgment.Single rule algorithm (1R) was adopted to learn.The risk factors influencing post-stroke patients' depression in extracted information were determined.Then the cases collected were divided into the training dataset (500 cases) and the test dataset (188cases).Optimal discriminant results were obtained by random forest model.Results Single rule algorithm showed that the most important influencing factor of post-stroke depression was stroke lesion site.By computer speculation,stroke lesions in the frontal and temporal lobes were most prone to post-stroke depression.Basal ganglia,brain stem,cerebellum,medulla oblongata and occipital lobe lesions were less likely to cause depression.The accurate classification rate could amount to 88.95％ (612/688 cases).Random forest model determination was made in the former 500cases in the training dataset.The total correct rate of determining depression was 98.2％.The total correct rate of determination in 188 cases of the test dataset was 99.47％.Six hundred and eighty-eight patients' data were learnt by random forest model.The total correct rate was 98.84％.The importance measure results showed that top 3 important indexes of post-stroke depression were lesion site,Chinese medicine intervention and depression family history.Conclusion Patients with lesions in the frontal & temporal lobes and depression family history were most prone to post-stroke depression.

Objective To explore the correlation between cytomegalovirus pneumonia (CMV-IP) and viral load in renal transplant recipients and to find out the threshold value of viral load for predicting CMV-IP. Methods The blood samples of 56 renal transplant recipients were taken weekly for the first 2 months and every 2 weeks for 2-6 months after transplantation.Real-time PCR were used to quantify the plasma CMV DNA.The mean viral loads of CMV-IP group and non-CMV-IP group in each time were compared using Wilcoxon test.Different cut-off values were tested to find the suitable values to predict the CMV-IP. Results Of the 56 recipients,8 (14.3%) developed CMV-IP.The viral loads were near zero in the first 4 weeks in both groups;from week 5 the viral load of CMV-IP group increased gradually and reached the climax at week 8 and then declined,but the load of non-CMV-IP group fluctuated at a low level.During weeks 5-11,the viral loads of CMV-IP group were higher than those of non-VMV-IP group.At 5,7 and 9 weeks,the differences of the viral loads between the 2 groups were significant (P

Objective To compare the effects of losartan and irbesartan on blood pressure,blood uric acid,insulin sensitivity and insulin resistance in female hypertensive patients complicated with hyperuricemia.Methods From August 2015 to December 2017,100 females of hypertension complicated with hyperuricemia who hospitalized in the Third People's Hospital of Ningxia were enrolled in the study.All the patients were divided into two groups according to the random digital table,with 50 cases in each group.The observation group was treated with losartan,and the control group was treated with irbesartan for 8 weeks.The total effective rate and adverse reactions were compared between the two groups.Also the changes of blood pressure,serum uric acid,fasting glucose (FBG),fasting insulin (FINS),high sensitivity C-reactive protein (hs-CRP),insulin sensitivity index (ISI) and insulin resistance index (HOMA-IR) were compared between the two groups after treatment.Results There was no statistically significant difference in the total effective rate between the two groups [92.0％ (46/50) vs.90.0％ (45/50)] (P ＞ 0.05).Before treatment,there were no statistically significant differences in blood pressure,serum uric acid,FBG,FINS,hs-CRP,ISI and HOMA-IR between the two groups (all P ＞ 0.05).After treatment,the systolic blood pressure and diastolic blood pressure in the two groups were (133.09 ± 10.11) mmHg vs.(131.54 ± 11.01) mmHg and (82.76 ± 6.23) mmHg vs.(83.75 ± 6.88) mmHg,which were lower than those before treatment (observation group:t =19.742,10.606,control group:t =18.925,-9.956,all P ＜ 0.05).But there were no statistically significant differences between the two groups (all P ＞ 0.05).After treatment,the serum uric acid in the observation group was lower than that in the control group [(387.21 ± 25.56) μmol/L vs.(429.67 ± 27.44) μmol/L] (t =8.006,P ＜ 0.05).The hs-CRP,FINS,HOMA-IR,ISI in the observation group were (4.92 ± 1.02) rmg/L,(15.92 ± 3.01) mU/L,(1.71 ± 0.24),(1.047 ± 0.095),which in the control group were (4.54 ± 1.00) mg/L,(17.23 ± 3.20) mU/L,(1.65 ± 0.27),(1.140 ± 0.083).After treatment,the hs-CRP,FINS,HOMA-IR in the two groups were decreased (all P ＜ 0.05),while ISI was increased (P ＜ 0.05).Furthermore,the improvement of FINS,ISI and HOMA-IR in the observation group was better than those in the control group (t =2.109,-5.213,3.191,all P ＜ 0.05).Conclusion Both losartan and irbesartan can improve clinical symptoms,lower blood pressure and improve insulin resistance in female hypertension patients complicated with hyperuricemia,and losartan is more effective than irbesartan.

OBJECTIVE: To explore the influencing factors of the occurrence of propagated sensation effects at Zusanli (ST 36) based on artificial intelligence technology. METHODS: A total of 272 undergraduates and postgraduates of Guangzhou University of TCM were recruited. The basic information, including TCM constitution, body weight index (BMI), pulse, tongue and coating, face complexion, as well as the occurrence of propagated sensation effects at Zusanli (ST 36) with different acupuncture needles and techniques, were recorded. The repeated incremental pruning to produce error reduction (RIPPER) algorithm was applied to predict the results and summarize the rules of relevant factors. RESULTS: ① The propagated sensation effects were often observed in the subject with -deficiency constitution (55 cases in total, of them 1 case was misclassified). ② The propagated sensation effects were observed in the subject with balanced - constitution (39 cases in total, of them 0 case was misclassified). ③ The propagated sensation effects were observed in the subject with phlegm-damp constitution combined with thin tongue and white coating (31 cases in total, of them 8 cases were misclassified). ④ The propagated sensation effects were observed in the subject with phlegm-damp constitution combined with light tongue coating (7 cases in total, of them 2 cases were misclassified). ⑤ The propagated sensation effects were observed in all the subject with special constitution (6 cases in total, of them 0 cases were misclassified). ⑥ The propagated sensation effects were not observed in the subject with other constitution or the combination of constitution and symptoms (134 cases in total, of them 4 cases were misclassified). The accuracy rate of classification was 94.49%. The difference of acupuncture needles and techniques was not significant in propagated sensation effects (>0.05). CONCLUSION The TCM constitution may be the most essential factor in the occurrence of propagated sensation effects.
