Objective: To explore the effect of induced labor on delivery outcome of pregnant women undergoing vaginal trial of labor after cesarean section. Methods: Totally, 173 pregnant women undergoing vaginal trial of labor after cesarean from April 1st, 2016 to October 31st, 2017 were involved. According to whether or not induced labor, pregnant women were divided into induced labor group (n=47) and natural labor group (n=126). The two groups of the general situation, the situation of delivery and delivery outcome were compared. Further more, the induced labor group were divided into cesarean section patients (n=20) and vaginal delivery patients (n=27) based on pregnancy outcomes, induction situation and delivery situation were analyzed. Results: (1) The gestational weeks was 39.2±1.1 in induced labor group, 38.7±1.0 in natural labor group. The 1-minute Apgar score was 9.98±0.15 in induced labor group, and 9.87±0.60 in natural labor group. The neonatal weight was (3 497±426) g in induced labor group, and (3 288±350) g in natural labor group. The thickness of lower uterine segment at 36-39 weeks of pregnancy was (2.4±0.6) mm in induced labor group, (2.1±0.6) mm in natural labor group. There were obviously differences in the gestational week, the 1-minute Apgar score, the neonatal weight and the thickness of lower uterine segment at 36-39 weeks of pregnancy between the two groups (all P<0.05). There were no significant differences in 5-minute Apgar score, the interval between previous cesarean delivery, postpartum hemorrhage, fetal distress, and intrauterine infection, secondary uterine inertia, placental abruption and uterine ruption between the two groups (all P>0.05). (2) In induced labor group, the cervical score of cesarean section patients was 3.8±1.7, while the cervical score of vaginal delivery patients was 5.2±1.7. The induced labor days of cesarean section patients was (1.6±0.9) days, while the induced labor days of vaginal delivery patients was (1.2±0.4) days. There were obviously differences in the cervical score and the induced labor days among the two subgroup patients (all P<0.05). There were no significiant differences in Apgar score, neonatal weight, the thickness of lower uterine segment at 36-39 gestational weeks and the interval times of previous cesarean delivery between the two subgroup patients (P>0.05). Conclusion Induction of labor does not reduce neonatal Apgar score, and does not increase the incidence of postpartum complications, and eliminats the increase of cesarean section rate caused by increased gestational weeks and fetal enlargement, and increases the vaginal delivery rate of pregnant women undergoing vaginal trail of labor after cesarean section.

Objective:To analyze the efficacy and safety of enzyme therapy in late-onset Pompe disease (LOPD) patients, so as to provide reference for the treatment and prognosis of LOPD.Methods:The effect of α-glucosidase (GAA) on a patient diagnosed with LOPD in the Affiliated Hospital of Jining Medical University was observed and analyzed. Besides, literature related to enzyme therapy in LOPD patients were searched in PubMed, Web of Science, Medline databases. Twenty-one studies containing clinical data from 910 LOPD patients related to enzyme therapy were finally included for analysis.Results:The patient developed muscle weakness since he was 16 years old. The GAA activity in peripheral blood was 0. Electromyography suggested myogenic lesions in both lower extremities. Compound heterozygous mutations of GAA gene were found by next- generation sequencing. Muscle biopsy revealed characteristic vacuolar changes. After eight years of diagnosis, the patient was given enzyme therapy for 18.5 months, 20 times in total. The symptoms of muscle weakness were slightly improved in the early stages of treatment without obvious adverse reactions. Most of the 910 LOPD patients were stabilized or had improved muscular and (or) respiratory function following treatment with GAA.Conclusion:GAA treatment is effective and well tolerated. In patients with advanced severe LOPD, enzyme replacement therapy remains effective even years after onset.

Objective:To analyze the clinical features and mutation of myeloid differentiation factor 88 (MYD88) L265P in patients with diffuse large B-cell lymphoma (DLBCL) of central nervous system (CNS).Methods:The clinicopathological materials of 45 cases of DLBCL of CNS were retrospectively collected in Xuanwu Hospital, Capital Medical University from September 2014 to February 2017. The clinicopathological data were retrospectively analyzed, combined with immunohistochemistry, EB virus in situ hybridization, imaging and medical history. The mutation of MYD88 L265P gene was detected by pyrosequencing and its clinical significance was analyzed. Results:The age of the patients ranged from 42 to 82 years [(57.6±8.8) years], including 24 males and 21 females. Totally 93.3% (42/45) of the patients had supratentorial tumours, which were single or multiple. The cerebral hemisphere (31/45, 68.9%) was the most common involved site, and 21 cases (21/45, 46.7%) had multiple lesions. Histologically, DLBCL in the CNS showed diffuse infiltration of tumor tissue, some of which grew around blood vessels in a "sleeve" arrangement. CD 20 and CD 79a were diffusely and strongly positive. Thirty-nine cases (39/45, 86.7%) were non-germinal center B cell (non-GCB) subtype and 6 cases (6/45, 13.3%) were germinal center B cell (GCB) subtype. MYD88 L265P mutation was found in 64.4% (29/45) patients. There was statistically significant difference between non-GCB type (71.8%, 28/39) and GCB type DLBCL (1/6, P=0.017). Compared with the operation/biopsy group without chemotherapy, operation+chemotherapy, biopsy+chemotherapy, operation/biopsy+chemotherapy+stem cell transplantation can improve the survival and prognosis ( HR=0.05, 95% CI 0.01-0.33 , P=0.002; HR=0.04, 95% CI 0.01-0.36 , P=0.004; HR=0.01, 95% CI 0.00-0.17 , P=0.001; respectively). Conclusions:DLBCL of the CNS is aggressive tumor with poor prognosis, the clinical manifestations are complex and diverse, and the diagnosis is challenging. MYD88 L265P is a common and specific gene mutation in primary CNS lymphoma(PCNSL), which is of great significance in the diagnosis and treatment of lymphoma. The MYD88 L265P mutation was more frequently detected in non-GCB than GCB subtype. Chemotherapy can improve the survival rate of PCNSL patients. If chemotherapy achieves complete remission and autologous hematopoietic stem cell transplantation is performed, there may be a chance of long-term survival.

Objective: To investigate current situation communication ability and training needs of standardized training nurses, in order to provide reference for improving the communication courses. Methods: A cross-sectional study was conducted and randomized sampling method was used to choose 100 nurses who participated in standardized training in Chengdu Fifth People′s Hospital. Nurses' communication ability was evaluated by Nurse-Patient Communication Ability Scale, and whose training needs of communication were investigated. Results: The average score of the Nurse-Patient Communication Ability Scale was 140.43±13.94. The educational background (t=-3.717, P<0.01), standardized training time (t=-2.812, P<0.01), and whether they had received communication training in the last year (t=2.231, P<0.05) had significant influence on nurse-patient communication ability. 88.00% (88/100) thought it necessary to carry out nurse-patient communication ability training during standardized training. Among them, 88.64% (78/88) hoped to carry out humanistic knowledge training, 65.91% (58/88) hoped that at least four training methods would be combined, and 44.32% (39/88) hoped that teachers from multiple disciplines would conduct training. Conclusions The nurse-patient communication ability of standardized training nurses needs to be improved. It is necessary to strengthen the theoretical research and curriculum design of training, pay attention to practical teaching, so that the training effect can be improved.
