Objective: To evaluate the effects of incretin-based therapies on body weight as the primary outcome, as well as on body mass index (BMI) and waist circumference (WC) as secondary outcomes. Methods: Databases including Medline, Embase, the Cochrane Library, and clinicaltrials.gov (www.clinicaltrials.gov) were searched for randomized controlled trials (RCTs). Standard pairwise meta-analysis and network meta-analysis (NMA) were both carried out. The risk of bias (ROB) tool recommended by the Cochrane handbook was used to assess the quality of studies. Subgroup analysis, sensitivity analysis, meta-regression, and quality evaluation based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) were also performed. Results: A total of 292 trials were included in this study. Compared with placebo, dipeptidyl-peptidase IV inhibitors (DPP-4Is) increased weight slightly by 0.31 kg [95% confidence interval ( ): 0.05, 0.58] and had negligible effects on BMI and WC. Compared with placebo, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) lowered weight, BMI, and WC by -1.34 kg (95% : -1.60, -1.09), -1.10 kg/m (95% : -1.42, -0.78), and -1.28 cm (95% : -1.69, -0.86), respectively. Conclusion GLP-1 RAs were more effective than DPP-4Is in lowering the three indicators. Overall, the effects of GLP-1 RAs on weight, BMI, and WC were favorable.

OBJECTIVE: To investigate the expression characteristics and clinical value of OTC4 gene in patients with myelodysplastic syndrome (MDS). METHODS: Sixty-five patients with MDS were selected from June 2017 to April 2018, and 39 healthy subjects were selected as control group. Mononuclear cells were isolated from bone marrow collected by aseptic puncture. The OTC4 gene level of MDS patients was detected by RT-PCR, and the OTC4 protein of MDS patients was detected by Western blot. The survival curve of MDS patients was drawn by Kaplan-Meier. Cox multivariate analysis was used to analyze the independent prognostic factors. RESULTS: The relative expression level of OTC4 gene in MDS patients was significantly higher than that in the control group (P＜0.05). Western blot showed that the expression level of OTC4 protein in MDS patients was higher than that in the control group (P＜0.05). OTC4 gene expression level closely related with the leukocyte count, and the level of hemoglobin, and lactate dehydrogenase and platelet count in MDS patients (P＜0.05). CR rate of MDS patients with low OTC4 gene expression was 54.8%, which was higher than that of high OTC4 gene expression group (P＜0.05), while HI, SD and PD rates of MDS patients with low OTC4 gene expression were 9.7%, 12.9% and 6.5% respectively, which were lower than those of high OTC4 gene expression group (P＜0.05). Kaplan-Meier survival analysis showed that OS and DFS in patients with low OTC4 gene expression were superior to those with high OTC4 gene expression (P＜0.05). Multivariate Cox regression analysis showed that leukocyte count and OTC4 gene were independent influencing factors for OS (P＜0.05), platelet level and OTC4 gene expression were independent influencing factors for DFS (P＜0.05). CONCLUSION OTC4 gene closely relates with the severity of MDS. The patients with lower expression of OTC4 gene have better prognosis, the detection of OTC4 gene has higher clinical value for evaluating the prognosis of MDS patients.

Objective To designe, synthesize a series of chlorin p₆ ether photosensitizers and preliminarily investigate their photodynamic antitumor activity based on previous research results that alkoxyl ether derivatives of 3-vinyl on chlorin f exhibited stronger photosensitive antitumor activity than parent compound. Methods Purpurin-18 (4) was obtained by oxidative degradation with air and alkali on pheophorbide a (5) which was prepared through acid hydrolysis of chlorophyll a from crude chlorophyll extracts in Chinese traditional herb named Silkworm excrement. Then, chlorin p₆ trimethylester (2) were formed via basic hydrolysis of internal anhydride ring for lead compound 3 and following immediately methylation with CH₂N₂. The intermediate 2 reacted with 33% HBr, following nucleophilic substitution with various alkoxyl alcohol to get six title compounds (1). All title compounds were subjected to photodynamic antitumor activity screening for melanoma B16-F10 cell in vitro. Results All title compounds showed much higher phototoxicity against melanoma B16-F10 cells than talaporfin and verteporfin. Their structures were confirmed by ¹H-NMR, ¹³C-NMR, ESI-MS and ESI-HRMS spectra. Conclusion Chlorin p₆ ether compounds were promising candidate photosensitizers for PDT applications due to theirs high dark toxicity/phototoxicity ratio and excellent phototoxicity, which were worthy of further research and development.

Objective To explore the action mechanism of moxibustion in treating Crohn's disease (CD) by observing the effect of herbal cake-partitioned moxibustion on the expression of NLRP3 inflammasome (NLRP3, ASC and Caspase-1) and IL-1β. Method Male Sprague Dawley (SD) rats of clean conventional grade were randomized into a normal control group (NG), a model control group (MG), a herbal cake-partitioned moxibustion control group (MoxG), and a sham moxibustion control group (SMG). The CD rat models were developed by using the mixture of 2, 4, 6-trinitrobenzene sulfonic acid (TNBS) and alcohol via enema. When the models were successfully developed, the MoxG received moxibustion intervention at bilateral Tianshu (ST25) and Qihai (CV6), and the SMG were administered by unlighted moxa cones. At the end of treatment, the length of each rats' colon and the colon macroscopic damage index (CMDI) score were recorded, the histopathological variations of rats' colons were observed by adopting HE staining and light microscope, and the expressions of NLRP3, ASC, Caspase-1 and IL-1β in rats' colons were determined by using immunohistochemical technique. Result Compared to the NG, the MG had its rats' colons present with severe damages, fissured ulcers and inflammatory cell infiltration with edema, and granulomas in submucosa of some colons, and its expressions of NLRP3, ASC, Caspase-1 and IL-1β increased significantly (P<0.05);compared to the MG, the MoxG had rats' colons present with improved structures and reduced intestinal inflammation, and its expressions of NLRP3, ASC, Caspase-1 and IL-1β dropped significantly (P<0.05); the SMG had its rats' colon inflammation present similarly to the MG, and its expressions of NLRP3, ASC, Caspase-1 and IL-1β had no significant difference (P>0.05). Conclusion Herbal Cake-partitioned moxibustion can down-regulate the expressions of NLRP3, ASC, caspase-1 and IL-1β in CD rats' colons to promote the repair of colon damage.

Objective To investigate the efficacy of scalp acupuncture with strong stimulation plus oral hiccup decoction in treating intractable hiccup. Method One hundred patients with intractable hiccup were allocated, using a random number table, to treatment and control groups, 50 cases each. In addition to oral hiccup decoction in the two groups, the treatment group received scalp acupuncture with strong stimulation at the stomach and chest areas and the control group, electroacupuncture, for two courses of treatment. The times to produce the effect and the symptom frequency scores were compared between the two groups. Result After one course of treatment, the cure rate, the cure and marked efficacy rate and the total efficacy rate were 42％, 66％ and 78％, respectively, in the treatment group and 24％, 40％ and 68％, respectively, in the control group. There were statistically significant difference in the cure rate and the cure and marked efficacy rate (P<0.05) but no in the total efficacy rate (P>0.05) between the two groups. After two courses of treatment, the cure rate, the cure and marked efficacy rate and the total efficacy rate were 68％, 78％ and 88％, respectively, in the treatment group and 40％, 60％ and 74％, respectively, in the control group. There were statistically significant difference in the cure rate (P<0.05) but no in the cure and marked efficacy rate and the total efficacy rate (P>0.05) between the two groups. After one and two courses of treatment, there was a statistically significant difference in the hiccup frequency score between the treatment and control groups (P<0.05). The time to produce the effect was 2-5 hrs in the treatment group and 5-8 hrs in the control group. Conclusion The total efficacy rate of scalp acupuncture with strong stimulation for intractable hiccup is not significantly different from that of electroacupuncture, but the cure rate of the former was significantly higher than that of the latter. Scalp acupuncture with strong stimulation can produce a quick effect, reduce the frequency of hiccups and relieve symptoms accompanying hiccup.

Objective To compare the function recovery of multiple injuries combined with floating knee joint injury and simple knee joint injury,and to analyze the risk factors.Methods A retrospective case control study was conducted to analyze the clinical data of 41 patients with multiple injuries combined with Blake and McBryde Ⅱ A floating knee injury admitted to Xijing Hospital of Air Force Medical University from June 2011 to June 2017.There were 26 males and 15 females,aged 18-76 years,with an average of 34.5 years.There were 25 patients with simple knee joint injury and and 16 patients with multi-joint combined injury involving knee joint and ipsilateral hip joint or ankle joint injury.Surgical fixation was performed in different parts by external fixation,intramedullary nail and plate screw fixation.According to the Kalstr(o)m and Olerud functional evaluation criteria,the excellent and good rate of postoperative functional recovery was compared between the two groups.The surgical fixation methods of the two groups were compared.Logistic regression analysis was performed on the influencing factors of functional recovery.Results The patients were followed up for 1-7 years,with an average of 3 years.The excellent and good rate of overall functional recovery in the two groups was 68％,and the rate was 84％ in simple knee injury group and 44％ in multi-joint combined injury group (P ＜ 0.01).There was no significant difference in the ratio of intramedullary nail and plate screw fixation between the two groups (P ＞ 0.05),while the proportion of the external fixation in the multi-joint combined injury group [31％ (5/16)] was significantly higher than that in the simple knee joint injury group [16％ (4/25)] (P ＜ 0.05).Logistic regression analysis showed that the rate of external fixation was an independent factor affecting the postoperative function (OR =0.15,P ＜ 0.01).Conclusions The postoperative function in multi-joint injury patients is poorer than in the single joint injury patients.The higher rate of using external fixation in multi-joint injury patients is a risk factor.For Blake and McBryde Ⅱ A floating knee injury combined with multi-joint injury,less external fixation should be used,so as to improve the postoperative function.

OBJECTIVE: To analyze the incidence of hemorrhagic cystitis (HC) after allogeneic hematopoietic stem cell transplantation and the factors affecting HC, so as to provide clinical evidence for further treatment of HC. METHODS: The HC of 113 patients after allogeneic hematopoietic stem cell transplantation in Affiliated Hospital of Xuzhou Medical University between the years 2014-2016 was analyzed respectively. All cases of HC were divided into HC group and non-HC(control) group. The follow-up time: from preeonditionig day to 180 d after transplantation. The 10 clinical parameters were selected for univariate analysis with COX regression analysis: sex, age (＜25 years and 25 years), primary disease, conditioning regimen with anti-thymoglobulin(ATG), sex-mismatch in recipients, haploidential HSCT, cytomegalovirus (CMV) viremia, EB viremia, graft-versus-host disease (GVHD), and primary disease relapse, the factors significant at the 0.1 level in univariate analysis should be further evaluated by multivariate analysis using a COX regression analysis. The difference was significant at P＜0.05 in multivariate analysis. RESULTS: The HC occured in 31 of 113 patients (27.4%), with 5 cases of grade I (5.5%), 19 of grade II (16.8%), 5 of grade III (4.4%), and 2 of grade IV (1.8%). The median time of HC onset was 37 days (26-70 d) after transplantation. The median duration of HC was 14 days (5-55d). Univariate analysis showed that conditioning with anti-thymoglobulin (ATG) (RR=6.170, 95%CI: 1.875-20.306, P＜0.01), CMV viremia (RR=7.633, 95%CI：2.318-25.133) (P＜0.01), haploidentical HSCT (RR=0.307, 95%CI：0.137-0.686, P＜0.01), GVHD (RR=1.891, 95%CI：0.918-3.898, P＞0.05) were the risk factors for recovery from HC. The multivatiate analysis of above-mentioned risk factors with statistical significance showed that only CMV viremia (RR=4.770, 95%CI: 1.394-16.326, P＜0.05) was the indentified risk factor affecting the recovery from HC. CONCLUSION Monitoring CMV viremia and antivirotic treatment are effective measurs to prevent the occurrence of HC and promote the recovery from HC.

OBJECTIVE: To investigate the clinical manifestations pathologic features, treatment options and prognosis of patients with bone lymphoma. METHODS: The clinical characteristics, pathologic features, treatment and prognosis of 34 BL patients diagnosed by histopathologic method or/and PET-CT and treated in first hospital of peking university from January 2004 to April 2018 were analyzed retrospectively. RESULTS: The median age of 34 BL patients was 56 years old, the male and female ratio was 1.43∶1 (24 /10). Among 34 patients, the patients with primary bone lymphoma(PBL) were 8 cases, the patients with secondary bone lymphoma(SBL) was 26 cases, the PBL and SBL ratio was 0.31∶1. Bone lymphoma lacks typical systemic symptoms, and its onset began mostly from bone pain and pathologic bone fracture. The most frequent pathological type of bone lymphoma in our study was diffuse large B-cell lymphoma (DLBCL), accounting for 55.88%. At present, the conventional treatment for bone lymphoma includes chemotherapy, or chemotherapy combined with radiotherapy and surgery, as well as hematopoietic stem cell transplantation. The average and median OS time of BL patients were 349 years and 3 years respectively, meanwhile the OS rate for three years and two years were 56.25% and 78.16%, respectively. Factors that affect survival of BL patients were PBL and SBL classification, pathological type, blood LDH level, and treatment methods. CONCLUSION Bone lymphoma is usually concealed onset，an adequate and adequate combination therapy can improve the survival rate and transplantation therapy plays an important role. Primary bone lymphoma is rare, the prognosis of patients with primary bone lymphoma is good, whereas the prognosis of patients with secondary bone lymphoma is poor.

OBJECTIVE: To investigate the effect of stably down-regulating the FMI expression of K562 cells on the sensitivity of K562 cells to Imatinib (IM) and its possible mechanism. METHODS: Western-blot was used to detect the expression of FMI protein in K562 cells and peripheral blood mononuclear cells from the patients with chronic myelogenous leukemia, chronic myeloid blast crisis and healthy volunteers. The specific interference sequences targeting at the human FMI gene were designed and ligated into the lentiviral vector LV3; the three plasmid system-packaged lentivirus particles were used to transfect K562 cells to screen K562 cells that stably down-regulated FMI. CCK-8 assay and flow cytometry were used to determine effect of IM on cell proliferation and apoptosis. The transcription level of FMI and Fz8 in leukemia cells was detected by fluorescent quantitative PCR. The protein expression levels of FMI, Fz8, NFAT1, BCR-ABL and β-catenin in leukemia cells were detected by Western-blot. RESULTS: The expression of FMI protein could be detected in peripheral blood mononuclear cells of the patients with CML-BC and K562 cells, the FMI expression could not be detected in all the patients with CML-CP and healthy volunteers. The recombinant lentiviral vector LV3/FMI had been successfully constructed the lentivirus was packaged, and the K562 cells stably down-regulating the FMI protein were screened. After stable down-regulation of FMI expression in K562 cells, the proliferation rate of leukemia cells decreased and the apoptosis rate was increased under the same drug concentration. Both the transcription and protein expression levels of Fz8 decreased. The NFAT1 total protein level increased, as well as the nuclear translocation of protein was enhanced. There was no significant change in the expression level of BCR-ABL fusion protein. The expression level of β-catenin protein decreased. CONCLUSION After the stable down-regulation of FMI expression, the sensitivity of K562 cells to IM and apoptosis of cells increase, which are performed possibly by inhibiting the FMI-Fz8 signaling pathway and activating the Ca-NFAT and Wnt/β-catenin signaling pathway.
