Objective To investigate the clinical efficacy of endoscopic selective varices devascularization and the modified Sandwich method on the treatment of esophagogastric varices. Methods 50 patients with esophagogastric varices were divided into therapy (endoscopic selective varices devascularization)group (n=25) and control group (n=25) by random number table method. The therapy group (n=25) received the treatment of endoscopic selective varices devascularization. The control group (n=25) was treated with modified Sandwich method injection. The success rate of hemostasis, rate of recurrent bleeding, rate of varices disappearance, complication rate, dosage of lauromacrogol and tissue adhesive, time of therapy and hospitalization days were compared and analyzed between the two groups. Results During the 3-month followup, the success rates of hemostasis were 100% in both groups 3 days after the treatments.

The rates of varices disappearance in therapy group and control group were 84%and 52% respectively, the difference (P=0.015) was statistically significant. There was no statistically significant difference in complication rates between the two groups(P>0.05). There was also no statistically significant difference in the average dosage of lauromacrogol and tissue adhesive between the two groups(P>0.05). The average time of therapy in therapy group and control group were(32.60±6.44)minutes and(40.60±7.26)minutes respectively, with statistically significant difference between the two groups(P=0.000). The average hospitalization days in therapy group and control group were(8.12±1.24)days and(9.12±1.39)days respectively, which is statistically significant difference between the two groups(P=0.010).

Objective To explore the clinical value of real-time ultrasound elastography combined with conventional ultrasound in assessing the stability of carotid atherosclerotic plaques in stroke patients. Methods Thirty-four patients with clinically confirmed stroke (stroke group) in our hospital were collected as the research object. Another 56 patients with carotid plaque but without stroke (control group) in the same period were selected as the control object for ultrasonic elastography detection, and the results were analyzed statistically. Results Thirty-four stroke patients were found 57 carotid atherosclerotic plaques, including 29 hypoechoic plaques, 21 mixed echoic plaques and 7 hyperechoic plaques; 56 control patients were found 75 carotid atherosclerotic plaques, including 22 hypoechoic plaques, 25 mixed echoic plaques and 28 hyperechoic plaques. There were significant differences between the number of plaques and the size of plaques (P<0.05). Carotid atherosclerosis low echo, mixed echo and strong echo plaque elasticity score increased in turn, the plaque hardness value increased in turn; the number of plaque scores between the two groups had statistical significance (P<0.05); for the same type of plaque hardness value between the two groups had no significant difference (P>0.05); There were significant differences in hardness values between the same types of plaques (P<0.05). Conclusion Ultrasound elastography may semi-quantitatively evaluate the stability of carotid atherosclerotic plaques in stroke patients. Different types of plaques have different elastic strain rates because of different tissue components. It may effectively complement the information deficiency of conventional ultrasound examination, and then evaluate the stability of plaques.

Methods Literatures on potential targets of dihydrotanshinone I in gastric cancer were searched in the database;GEPIA database tool was used to analyze the potential mechanism of dihydrotanshinone I on gastric cancer;taking analysis of the correlation between potential target genes and genes expressing key antioxidant stress proteins;We had analysis of expression level of dihydrotanshinone I on potential target genes in gastric cancer patients;and prognostic analysis of dihydrotanshinone I on potential target genes in gastric cancer patients. Results The main targeting genes(proteins) of dihydrotanshinone I on potential target genes were hypoxia inducible factor-1(hif-1) and citrulline histone H3(CITH3), whose genes were HIF1 A and NOS2, respectively;GEPIA database showed that there was a positive correlation between HIF1 A and CAT(P=2e-04, R=0.18), GPX1(P=0.033, R=0.11), or NFE2L2(P=0, R=0.41), while NOS2 only had a positive correlation with SOD1(P=0.21, R=0.18), and no correlation with other three genes. The expression levels of HIF1 A and NOS2 in gastric cancer tissues were higher than those in normal adjacent gastric tissues. The overall survival rate of patients with gastric cancer decreased with the high expression of HIF1 A. Conclusion Dihydrotanshinone I may induce apoptosis of AGS cells through reactive oxygen species mediated oxidative stress, and inhibit the expression of HIF1 A and NOS2, thus inhibit their antioxidative stress, which may improve the overall survival rate of gastric cancer patients.

Objective To explored the risk factors of gastrointestinal symptoms after operation by retrospectively analyzing the clinical records of patients with mixed hemorrhoids treated by Milligan-Morgan operation in our hospital in recent 8 years. Methods 1 221 patients with mixed hemorrhoids treated by Milligan-Morgan operation in our hospital from January 2012 to June 2016 were divided into two groups: the group with digestive tract symptoms after operation and the group without digestive tract symptoms. The differences between the two groups were compared and the related risk factors were analyzed. Results Among 1 221 patients with mixed hemorrhoids, 168 had gastrointestinal symptoms, whose incidence was 13.8%(168/1 221). Univariate analysis showed that hypertension and general anesthesia were the related factors of gastrointestinal symptoms after operation, and the difference was statistically significant. Multivariate logistic regression analysis showed that hypertension and general anesthesia were the independent risk factors. Conclusion Milligan-Morgan operation for mixed hemorrhoids has a high incidence of digestive tract symptoms. Perioperative blood pressure control and careful selection of general anesthesia may effectively reduce the incidence of digestive tract symptoms.

Objective To investigate the immunophenotype features of children with acute B-lymphoblastic leukemia(B-ALL) combined with fusion gene expressing after to analyze the results of the 43 fusion genes. Methods Real-time fluorescent probe PCR assay was used for the detection of fusion genes in 120 cases of children from Shenzhen Children's Hospital with B-ALL newly or recurrently diagnosed from Oct 2016 to Dec 2018. Multi-parameter flow cytometry(FCM) was used for the detection of the immunophenotype in children with B-ALL. Results Of all the 120 cases, the fusion genes were detected at positive rate of 37.5%(45/120), included TEL/AML1 27 cases, E2 A/PBX1 7 cases, BCR/ABL1 6 cases, MLL 4 cases, TLS/ERG 1 cases. The positive rate of leukemia fusion gene had statistically difference among fusion genes positive groups based on age(P<0.01). There was no statistically difference in the gender distribution(P>0.05). The expressing of CD19 was at positive rate of 100% in all of the groups. The rate of the common-B-ALL was the highest B-ALL subtype in the TEL/AML1 positive groups(77.8%). The stem /progenitor associated antigen CD34 was at positive rate of 81.5%. The pre-B-ALL was the main subtype in the E2 A/PBX1 group, which was no expression of the known T-ALL associated antigen MyAg antigen. There was statistically difference in the positive rate of MyAg expression among all of the groups(P<0.01), with the highest rate in the BCR/ABL1 group(100%). Conclusion There were certain distribution features in age composition and immunophenotype of children with B-ALL carrying five kinds of common fusion genes. The characteristic changes of the immunophenotype of B-ALL may be used to predict the expression of fusion genes and improve the accuracy of fusion genes by the supplementary role of immunophenotype analysis.
