Objective To explore the levels and the significance of IL-11 and soluble glycoprotein 130(sgp130) in the treatment of new-diagnosed acute leukemia(AL) during the induced remission. Methods The levels of IL-11 and sgpl30 in 47 patients with acute leukemia were determined by ELISA respectively before treatment and after completed remission(CR), and the number of white blood cell (WBC) and platelet (Plt) were valued by hametometry. Results Plasma IL-11 level of AL patients was significantly lower than normal (P ＜0.05), and increased obviously to the normal level when complete remission was achieved. And it correlated with PLT counts. While sgp130 level was higher than normal (P＜0.05),and declined after CR and correlated with WBC counts. Conclusion The plasma IL-11 and sgp130 levels can be helpful for confirming the diagnosis,evaluating the efficiency and predicting the prognosis of AL.

Objective To investigate the therapeutic effect and mechanism of total flavone of haw-thorn leaf ( TFHL) on p38MAPK signaling pathway and inflammation factors in rats brain with chronic cere-bral ischemia.Methods SPF class healthy male SD rats were randomly divided into sham group, model group,TFHL group and Ginkgo leaf group( 12 rats in each group) .Permanent bilateral carotid artery ligation was used to prepare chronic cerebral ischemia model.Morris water maze method was used to evaluate learn-ing and memory abilities of rats.Immunohistochemistry and Western blot methods were used to measure the expression of caspase-3 and p38MAPK proteins.ELISA method was used to measure the amounts of TNF-αand IL-1βin hippocampal tissue.Results Compared with the model group,TFHL treatment (36 d) can im-prove learning and memory capabilities of vascular dementia rats,shorten the escape latency ( TFHL group(10.01±2.85) s vs Model group (19.54±6.12) s, P<0.05) and the course of searching platform(TFHL group(2.6044±0.3219)m vs model group(3.3502±0.6231)m, P<0.05),increase the numbers of crossing the platform (TFHL group(5.17±2.12) times vs Model group (3.96±1.34) time,s P<0.05) and the platform quadrant swimming distance percentage (TFHL group(48.22±7.39)%vs model group (33.42±5.32) %, P<0.01).The number of caspase-3 positive cells in the hippocampus significantly reduced (TFHL group(1.677 ±0.164) vs Model group (2.387±0.171), P<0.05),the expression level of P38MAPK protein (TFHL group (0.0161±0.0003) vs Model group (0.0254±0.0018), P<0.05),TNF-α(TFHL group(19.61±3.61) ng/10 mg vs Model group (27.82±6.57) ng/10 mg, P<0.01)and IL-1β(TFHL group(24.41±2.56) ng/10 mg vs Model group (29.43±5.26) ng/10 mg, P<0.05) were significantly decreased.Conclusion TFHL plays a protective role in nerve function of the chronic cerebral ischemia rats.The mechanism of its antia-poptosis might be associated with the activation of P 38MAPK signaling pathway,inflammation and the apoptosis of neurons in the brain.

Results The area under ROC curve of UCDSS was 0. 977, the sensitivity and specificity was 92.0%, 92.3% respectively. Conclusions The classification based on the UCDSS may increase the diagnostic accuracy of the differentiation between benign and malignant breast solid nodular lesions.

Objective:To explore the effect of multi-channel health education model by professional team on drug compliance, disease knowledge and recurrence in rate of inflammatory bowel disease (IBD) patients, so as to provide basis for formulating scientific health education measures.Methods:From February 2016 to February 2019, IBD patients visited First Affiliated Hospital of Kunming Medical University were selected. According to whether they received health education, the patients were divided into intervention group (100 cases) and control group (138 cases). Morisky medication adherence scale-8 (MMAS-8) and Chinese version of Crohn′s and colitis knowledge score (CCKNOW) were used to evaluate treatment compliance and disease knowledge. The score of MMAS-8, the proportion of poor drug compliance, CCKNOW score and recurrence rate at 48 weeks of follow-up were compared between the intervention group and control group. Two sample t test and chi-square test were used for statistical analysis. Results:The total scores of MMAS-8 and CCKNOW of the intervention group were both higher than those of the control group (5.58±1.96 vs. 4.47±1.44, 10.87±4.21 vs. 9.23±4.65), and the differences were statistically significant ( t=-5.06 and -2.79, both P<0.05). The proportion of patients with poor drug compliance and recurrence rate at 48 weeks of follow up of the intervention group were both lower than those of the control group (56.0%, 56/100 vs. 86.2%, 119/138; 20.0%, 20/100 vs. 31.9%, 44/138), and the differences were statistically significant ( χ2=38.18 and 4.17, both P<0.05). Conclusions:Multi-channel health education by professional team can effectively improve the drug compliance and disease knowledge in IBD patients, improve patient self-management ability, and reduce the recurrence rate.

Objective: To study the effects of TNF ? on wound healing. Methods: The skin lesion and incisions were made on mice and rh TNF ? was applied in both skin lesion and incision. Tissue strips were evaluated for tensiometry and histologic features after healing. Results: It was found that rh TNF ? markedly improved wound healing both in skin lesion and incision wound model, it also markedly enhanced the breaking strength of treated incision and increased wound cellularity in rh TNF ? treated groups. Conclusion: The results suggest that TNF ? play an important role in regulating inflammatory reactions of local injured tissues and it may improve the functions of fibroblasts, mononuclear phagocytes and endothelial cells. rh TNF ? of suitable doses can promote wound healing. This shows that TNF ?, as a wound healing promoter, has the potentials for clinical application.

Objective: To study the relationship between interleukin(IL) 6, IL 8, tumor necrosis factor alpha (TNF ?) and wound healing. Methods: In lower jaw gunshot wound, the expression of IL 6, IL 8, TNF ? in local soft tissues was assayed by using immunohistochemistry methods. The current levels of IL 6, IL 8, TNF ? in wound tissues was analysed by using image assay. Results: High expressions of these cytokines were observed in local soft tissues of wounds during the first 3 d after the gunshot. The cytokines expressions were different between the area near the bullet path and that far from the path. There was only one peak of the cytokines concentration in the area far from the bullet path, while there were 2 peaks of the cytokines concentration in the area near the bullet path.Conclusion: These results suggest that IL 6, IL 8, TNF ? play an important role in regulating inflammatory reactions of local injured tissues. They may improve the functions of fibroblasts, mononuclear phagocytes and endothelial cells and stimulate wound cells to produce and release other cytokines.

To examine the effect of Gankang Suppository on duck hepatitis B virus (DHBV), the serum biochemistry and hepatic histology in an animal model of DHBV infection, a model of DHBV infection was established by infecting 1-day-old Yingtaogu ducklings with DHBV-positive serum. The successful model was confirmed by PCR assay and 48 ducklings infected with DHBV were randomly divided into 3 groups: a Gankang Suppository treatment group, an acyclovir (ACV) group and a DHBV model group (control), with each group having 16 animals. All the animals were given the medicines for 4 weeks in a row. The serum of the animals was taken 14 and 28 days after the medication and 7 days after drug discontinuation. Real-time PCR was performed to detect the copy numbers of DHBV DNA in the serum. ALT and AST were dynamically monitored. The ducklings were sacrificed on the 7th day after the discontinuation of the treatment and livers were harvested and examined for inflammation and degeneration of liver cells by using HE staining. The results showed that on day 14, 28 after the treatment and day 7 after the withdrawal, the logarithmic values (log) of DHBV DNA copy numbers in ducklings of Gankang Suppository treatment group were significantly lower than that before the treatment (P=0.0092, P=0.0070, P=0.0080, respectively). Compared with DHBV model control group, the ALT level was significantly decreased (P=0.0020, P=0.0019, respectively) on day 28 after the treatment and on day 7 after the withdrawal. The AST level was also reduced on day 14 after the treatment (P=0.0298). Compared with the ACV control group, the level of ALT was lower on day 7 after the withdrawal (P=0.0016). Histologically, the hepatocyte swelling, vacuolous degeneration and acidophilic degeneration in Gankang Suppository treatment group were alleviated 7 days after the withdrawal as compared with model control group (P=0.0282, P=0.0084, P=0.0195, respectively). It is concluded that Gankang Suppository can effectively suppress DHBV replication, reduce the levels of serum ALT and AST and improve hepatic histology.

Objective To determine the main CT features and the key points of differential diagnosis of multilocular cystic renal cell carcinoma (MCRCC) classified according to 2004 WHO pathological diagnostic criteria. Methods According to the criteria, 40 patients were divided into two groups: MCRCC group and other subtypes of cystic renal cell carcinoma (CRCC). The CT findings were evaluated and compared between two groups for cystic content, wall, septum, nodularity, calcification and enhancement. ROC curve was used to determine the cut-off value of the possible CT feature which could distinguish MCRCC from other subtypes of CRCC. Results Seventeen cases of MCRCC group and 23 cases of CRCC group were included in this study according to the diagnostic criteria. MCRCC appeared as a well defined multilocular cystic mass with thin wall and sepia and no expansile solid nodules. Thickness of cystic wall and/or septum is was main CT findings to distinguish MCRCC from other subtypes of CRCC (P ＜ 0.01 ). The cut-off value of the thickness was 6 mm and its sensibility, specificity was 89% ,75% respectively. Conclusion Cystic wall and/or septum with a thickness of less than 6 mm are the main CT findings to dis tinguish MCRCC from other subtypes of CRCC.
