OBJECTIVETo explore the effect of different nutrition therapies on abnormal glucose metabolism during pregnancy and pregnancy outcomes.

METHODSThe 83 cases of pregnant women with abnormal glucose metabolism who came to nutrition clinic were randomly divided into two groups before 30 weeks pregnancy: 42 cases in traditional food exchange serving group (FES) and 41 cases in food exchange serving based on glycemic load group (FES + GL). Traditional food exchange serving and food exchange serving based on glycemic load were used as the different nutrition therapies for two groups respectively until the time of delivery. The influence of two nutrition therapies on the blood glucose and pregnancy outcomes were observed.

RESULTSThe daily food glucose load (GL) after nutrition therapy in the FES + GL group (145.9 ± 26.3) were significantly decreased than that of the FES group (179.9 ± 28.9, t = 5.602, P < 0.01). Fasting plasma glucose (FPG) and 2 h postprandial glucose (2 h PG) ((4.63 ± 0.97) and (6.15 ± 1.07) mmol/L, respectively) after nutrition therapy in the FES + GL group were significantly lower than that in pre-nutrition therapy ((4.96 ± 0.81) and (9.13 ± 1.61) mmol/L, t = 2.237, 11.202, respectively, all P values < 0.05). The 2 h PG in the FES + GL group ((6.15 ± 1.07) mmol/L) after nutrition therapy was significantly lower than that of the FES group ((6.86 ± 1.26) mmol/L, t = 2.760, P < 0.05). 19.51% (8/41) of the total incidence of complications in the FES + GL group was lower than that (11/42, 26.19%) in the FES group, but the difference was not significant (χ² = 0.524, P > 0.05).

CONCLUSIONFES based on GL was much easier to reduce blood glucose compared with FES. Two nutrition therapies can improve maternal and neonatal outcomes in pregnant women with abnormal glucose metabolism.

OBJECTIVETo study on mechanisms of acupuncture in relieving visceral pain.

METHODSIn SD rats CRD was used as noxious visceral stimuli. Activities of spinal dorsal horn wide dynamic (WDR) neurons of L1-L13 were recorded by extracellular microelectrode technique. Acupuncture was given at ipsi-lateral and contra-lateral Zusanli (ST 36) of the same segmental innervation of rectum and colon.

RESULTSVisceral noxious afferent could significantly activate spinal dorsal horn convergent neurons, and mechanical stimulation of contra-lateral body surface and hand acupuncture at Zusanli (ST 36) could inhibit this noxious response. When the spinal cord was acutely blocked, the inhibiting CRD effect of needling CRD effect of needling contra-lateral Zusanli (ST 36) completely disappeared.

CONCLUSIONAcupuncture and visceral noxious afferent signals converge and interact each other in spinal level, and acupuncture at acupoint can inhibit the spinal dorsal horn neuron respon se activated by visceral noxious afferent and this action needs the participation of the center above the spinal cord.

Objective To evaluate MR imaging findings of uveal metastases.Methods MR imaging findings of 20 cases with uveal metastases comfirmed by pathology or follow-up were retrospectively analyzed.MR imaging was performed in 20 patients,of which postcontrast T1-weighted imaging was performed in 19 patients including dynamic contrast enhancement scanning in four cases.Results Metastatic tumor was found in the iris and ciliary body in two cases,and in choroid in 18 cases.The tumor demonstrated slightly hypointense signal on Tl-weighted imaging and isointense signal on T2-weighted imaging in two cases,isointense signal on T1-weighted imaging and isointense signal on T2-weighted imaging in nine cases,isointense signal on T_1-weighted imaging and slightly hyperintense signal on T_2-weighted imaging in three cases,isointense signal on T_1-weighted imaging and slightly hypointense signal on T_2- weighted imaging in three cases,slighdy hyperintense signal on T_1-weighted imaging and slightly hypointense signal on T_2-weighted imaging in two cases,and slightly hyperintense signal on T_1-weighted imaging and slightly hyperintense signal on T_2-weighted imaging in one case.The tumor appeared as mild thickness of the wall of the globe in eight cases,a crescent mass in three cases,a fusiform mass in seven cases,and a nodule in two cases.Nineteen patients showed moderate or marked enhancement on postcontrast T_1-weighted imaging.The time-intensity curve of dynamic contrast enhancement in four patients suggested a rapid enhancement and slow washout pattern.Retinal detachment was observed in 11 patients and abnormal signal intensity within the vitreous body was seen in two cases.Conclusion MRI can display the location,shape, signal characteristics,and enhancement pattern of uveal metastases,contributing to diagnosis and differential diagnosis.

OBJECTIVETo assess the early therapeutic and cognitive effect of repetitive transcranial magnetic stimulation (rTMS) combined with antidepressant medication in treatment of first-episode patients with major depression.

METHODSSixty first-episode depressed inpatients aged 18-45 y, who met the DSM-IV clinical criteria for major depressive episode were randomly assigned to citalopram treatment (20 mg/d) in combination with a two-week period of either rTMS (study group)or sham procedure (control group) on left dorsal-lateral prefrontal cortex (10 Hz, 90% motor threshold). The Hamilton Depression Rating Scale (HAMD) was used to assess the severity of depression. The Wisconsin Card Sorting Test (WCST) and Continuous Performance Test (CPT) were used to assess cognitive function of depression.

RESULTThe response rate was significantly greater in the study group compared to the control group after treatment (57% compared with 29%,P<0.05). The HAMD scores significantly declined after treatment in two groups, and the study group showed lower scores compared to the control group after 2 weeks (P<0.01). Neuropsychological assessments showed that there was no significant difference between the two groups except for the significant improvement in the categories on WCST in study group compared to the baseline (P<0.05) and the control group (P<0.05)after 2 weeks treatment. No serious event occurred in the patients during the rTMS study.

CONCLUSION10 Hz rTMS enhances early effects of citalopram and improves cognitive function in first-episode major depressive patients.

Ras is best known for its ability to regulate cell growth, proliferation and differentiation. Mutations in Ras are associated with the abnormal cell proliferation which can result in incidence of all human cancers. Extracellular signal-regulated kinase (ERK) is a downstream effector of Ras and plays important roles in prognosis of tumors. Recently, evidence has gradually accumulated to demonstrate that there are other effectors between Ras and ERK, these proteins interact each other and constitute the thorough Ras/Raf/MEK/ERK signaling pathway. The pathway has profound effects on incidence of esophageal carcinoma and clinical applications of some chemotherapeutic drugs targeting the pathway. Further understanding of the relevant molecular mechanisms of Ras/Raf/MEK/ERK signaling pathway can be helpful for the development of efficient targeting therapeutic approaches which contribute to the treatment of esophageal cancer. In this article, roles of Ras/Raf/MEK/ERK signaling pathway in esophageal carcinoma as well as pharmacological targeting point in the pathway are reviewed.

BACKGROUNDInvolvement of peripheral nerves in dermatomyositis (DM) and polymyositis (PM) is less well known. In the present study we retrospectively analyzed the clinical and electrophysiological records of hospital inpatients with a diagnosis of DM or PM to investigate the association of DM/PM and peripheral neuropathy.

METHODSThe data of inpatients diagnosed with DM or PM were collected in Peking Union Medical College Hospital, and 186 patients (118 patients with DM and 68 with PM) were retrospectively analyzed. Nerve conduction studies (NCSs) of the median nerve, ulnar nerve, posterior tibial nerve, and common peroneal nerve were examined simultaneously.

RESULTSThere were 71 (38.2%) patients with abnormal NCS findings, 37 (19.9%) with pure motor involvement (decreased compound muscle action potential, CMAP), and 34 (18.3%) with peripheral neuropathy. Of the 34 peripheral neuropathy patients, 14 (7.5%) had polyneuropathy, 1 (0.5%) had multiple mononeuropathy, 16 (8.6%) had carpal tunnel syndrome (CTS), 1 (0.5%) had trigeminal sensory neuropathy, 1 (0.5%) had ulnar sensory neuropathy, and 1 (0.5%) had brachial plexus involvement. The prevalence of malignant disease (3/34, 8.8%), other connective tissue diseases (CTDs) (7/34, 20.6%) and diabetes (6/34, 17.6%) was significantly greater in DM/PM patients with peripheral neuropathy (chi(2) = 15.855, P = 0.000) compared with DM/PM patients without involvement of peripheral nerves (5/115, 4.3% and 7/115, 6.1%, respectively).

CONCLUSIONSPeripheral neuropathy in DM/PM often suggests a complication with cancer, other CTDs, diabetes or CTS. From a practical point of view, NCS for DM/PM may help find the underlying disorders.

OBJECTIVETo summarize long-term outcomes of childhood lymphoblastic lymphoma (LBL) with protocol CCCG-97 and -2002.

METHODSFrom November 1998 to October 2010, 70 consecutive newly diagnosed childhood LBL (5 B-LBL and 65 T-LBL) were enrolled in this study, in which 22 received CCCG-97 and 48 CCCG-2002 protocols. St.Jude staging system was adopted. Patients were divided into three risk groups based on clinical stage and serum LDH, and received chemotherapy with different intensity. The factors, which were possibly associated with the prognosis, were analyzed. The survival rates were evaluated by Kaplan-Meier analysis.

RESULTSThe patients were 1.5 to 14 years old with the median age of 8 years old. They were evaluated as stage I-II for 6 , stage III41, and stage IV23 (15 were BM positive and 8 multiple bone metastases). Until Dec.31th, 2011,the mean follow-up was 62.5 months (range, 14 to 161 months) with the median follow-up of 48 months. 1-year overall survival (OS) was 74.3%, and 5- year event-free survival (EFS) 64.1% (abundance as event). Thirteen patients were complicated with serious condition during chemotherapy and 1 died of complication. Univariate analysis indicated that delayed and/or non-completed response on days 33 and 63 of induction was the unfavorable prognostic factor.

CONCLUSIONPrimary LBL usually located in the mediastinum. 90% of the patients was at advanced stage III-IV at first presentation. The 5-year EFS was 64.1%. Patients not achieved CR at days 33 and 63 at the end of induction was a poor prognostic factor.

Objective: To analyze the clinical and laboratory characteristics, and prognosis of adult acute myeloid leukemia (AML) patients with MLL gene rearrangements. Methods: The medical records of 92 adult AML patients with MLL gene rearrangements from January 2010 to December 2016 were retrospectively analyzed. Results: 92 cases (6.5%) with MLL gene rearrangements were identified in 1 417 adult AML (Non-M(3)) patients, the median age of the patients was 35.5 years (15 to 64 years old) with an equal sex ratio, the median WBC were 21.00(0.42-404.76)×10(9)/L, and 78 patients (84.8%) were acute monoblastic leukemia according to FAB classification. Eleven common partner genes were detected in 32 patients, 9 cases (28.1%) were MLL/AF9(+), 5 cases (15.6%) were MLL/AF6(+), 5 cases (15.6%) were MLL/ELL(+), 2 cases (6.3%) were MLL/AF10(+), 1 case (3.1%) was MLL/SETP6(+), and the remaining 10 patients' partner genes weren't identified. Of 92 patients, 83 cases with a median follow-up of 10.3 (0.3-74.0) months were included for the prognosis analysis, the complete remission (CR) rate was 85.5% (71/83), the median overall survival (OS) and relapse free survival (RFS) were 15.4 and 13.1 months, respectively. Two-year OS and RFS were 36.6% and 29.5%, respectively. Of 31 patients underwent allogeneic hematopoietic stem-cell transplantation (allo-HSCT), two-year OS and RFS for patients received and non-received allo-HSCT were 57.9% and 21.4%, 52.7% and 14.9%, respectively (P<0.001). Among patients with partner genes tested, 9 of 32 cases (28.1%) were MLL/AF9(+), the median follow-up was 6.0(4.1-20.7) months. 3 patients with MLL/AF9 underwent allo-HSCT. 23 cases (71.9%) were non- MLL/AF9(+), the median follow-up was 7.8 (0.3-26.6) months. 14 patients (60.1%) with non-MLL/AF9 underwent allo-HSCT. One-year OS for patients with MLL/AF9 and non-MLL/AF9 were 38.1% and 55.5%, respectively (P=0.688). Multivariate analysis revealed that high WBC (RR=1.825, 95% CI 1.022-3.259, P=0.042), one cycle to achieve CR (RR=0.130, 95% CI 0.063-0.267, P<0.001), post-remission treatment with allo-HSCT (RR=0.169, 95% CI 0.079-0.362, P<0.001) were independent prognostic factors affecting OS. Conclusions: AML with MLL gene rearrangements was closely associated with monocytic differentiation, and MLL/AF9 was the most frequent partner gene. Conventional chemotherapy produced a high response rate, but likely to relapse, allo-HSCT may have the potential to further improve the prognosis of this group of patients.

OBJECTIVE: To explore the clinical features and therapeutic efficacy in adult ALL patients with t (1; 19) (E2A-PBX1). METHODS: The clinic data of 19 adult ALL patients with t (1; 19) (E2A-PBX1) in our hospital from Nov. 22, 2010 to Apr. 4, 2018 were collected. The clinical features,complete remission (CR) rate, overall survival (OS) rate and relapse-free survival (RFS) rate of patients received chemotherapy and chemotherapy+HSCT were analyzed. RESULTS: In all the 19 patients, the median age was 24 (14-66), median WBC count was 16.47×109 (1.8-170.34)/L, median Hb level was 98 (65-176) g/L, median Plt count was 50 (15-254)×109/L. Pre B-ALL were 17 cases (89.5%), and common B-ALL were 2 cases (10.5%). Patients received the induction therapy, the overall CR rate was 94.7%, one course CR rate was 94.7%, 4 year OS rate was 47.1% and RFS rate was 43.3%. The OS rate and RFS rate of patients received transplantation were slightly higher than those of patients not received transplantation (OS: 62.5% vs 36.7%) (P=0.188)；RFS (62.5% vs 38.9%) (P=0.166). CONCLUSION Most adult ALL patients with t (1; 19) (E2A-PBX1) is Pre B-ALL by Immunophenotyping, as compared with the pediatric patients, the therapeutic efficacy for adult patients with t (1; 19) (E2A-PBX1) is worsen, therefore, stem cell transplantation is still acquired for better long term survival.

OBJECTIVETo investigate the incidence of karyotypes and gene mutations for elder acute myeloid leukemia and to explore the relationship between each other.

METHODSClinical data and bone marrow samples of elder AML patients were collected. Karyotype and gene mutation (FLT3, NPM1, C-Kit, CEBPα, DNMT3A) test were performed, characteristics of karyotypes and gene mutations were analysed.

RESULTSThe incidence of better risk karyotype was 16.6%, in which the incidences of t(15;17), t(8;21) and inv (16)/t(16;16) were 3.90%, 10.73%, and 1.95% respectively; the incidence of intermediate risk karyotype was 72.2%, in which the incidence of normal karyotype was 57.86%; the incidence of poor risk karyotype was 11.20%, in which the incidence of of MLL/11q23, complex karyotype and monosomal karyotype were 1.95%, 6.34%, 5.85% respectively; the incidences of FLT3, NPM1, C-Kit, CEBPα, DNMT3A mutation were 12.57%, 22.06%, 2.16%, 14.71%, 15.71% respectively. Compared with patients older than 60 years, patients with age of 55-60 years were with less complex karyotype (1.09% vs 10.62%)(P=0.003) and monosomal karyotype (2.17% vs 8.85%)(P=0.032), and more t(8;21)(17.39% vs 5.31%)(P=0.008) and inv (16)/t(16;16)(4.35% vs 0.00%)(P=0.045).

CONCLUSIONFor older AML patients, great difference in the distribution of karyotyes was found between the patients older than 60 years and patients with age of 55-60 years, while no such characteristics was found for gene mutations. Good elucidation of karyotypes and gene mutations are key for the treatment of older acute myeloid leukemia patients.
