With the development of phamacogenomic and molecular biology, it has been revealed that the curative effect of non-small-cell lung cancer (NSCLC) is closely related to tumor molecular markers. Predictive biomarkers in NSCLC patients, including ERCC1, BRCA1, hMLH1, hMSH2, RRM1, β-tubulin, TS,EGFR and K-ras, can predict individual patient's response to chemotherapy or targeted therapy, making individualized therapy be possible.

Tumor bone metastasis is one of the common complications of advanced tumor and one of the signs of poor prognosis.There are many targeted drugs for bone metastasis in the clinic,which play a very important role in the antitumor treatment and prevention of bone related events.Among them,zoledronic acid,a representative bisphosphonate drug,has been extensively studied.It has been found that zoledronic acid combined with other anti-tumor therapies can more effectively inhibit the occurrence of tumor and bone-related events.This article reviews the latest research on zoledronic acid combined with other antitumor methods to guide clinical use and provide research ideas.

Objective To understand the prevalence of alcohol dependence in individuals living in Guangxi Zhuang Autonomous Region,China. Methods From July 2007 to December 2007,21290 subjects aged more than 15 were randomly selected for 6 Prefecture-level cities and 10 counties by stratified multi-stage cluster sampling method. All subjects were investigated by face to face interview. The Chinese version of Composite International Diagnostic Interview (CIDI3.0) Provided by the Chinese Center for Disease Control And Prevention was used as the screening tool and the diagnoses were made with the 10th edition of international classification of Disease Criteria. Results 18 219 subjects completed the screening,the Completion rate was 85.58‰. The general point prevalence and the general lifetime prevalence of alcohol dependence in individuals living in Guangxi was both 4.50‰. The general lifetime prevalence was higher in rural (6.17‰) than in urban (1.85‰) ( RR =0.31,95% CI =0. 17 ～0.57, P=0. 000) ,higher in men (8.59‰) than in women (0. 33‰) ( RR =0.04,95% CI =0. 01 ～ 0.13, P = 0.000 ) and higher in Zhuang (9.63‰) than in Han(1.95‰) ( RR = 5. 01,95% CI = 3.02 ～8.34, P = 0.000). The lifetime prevalence of alcohol dependence tends upwards as age increasing (P＜0.05 ) and it differs in different marital status,higher in divorce groups (P ＜ 0.05). Conclusion Schizophrenia, Depression disorder, Alcohol dependence disorder are the most common mental disorders and have become the public health problem in Guangxi. To do this,it is necessary to carry out targeted research in prevention and rehabilitation.

Objective:To analyze the characteristics of prenatal MRI and postnatal CT images of fetal congenital mesoblastic nephroma (CMN).Methods:We retrospectively recruited three women with a singleton pregnancy suspected of having fetal CMN by prenatal imaging examination and confirmed by postpartum surgical resection and pathological examination at Guangzhou Women and Children Medical Center from August 2017 to April 2019. The prenatal MRI, postnatal CT, and pathological examination data were analyzed to summarize the image features of fetal CMN using descriptive statistical analysis.Results:(1) The total number of deliveries in the setting during the same period was 57 716, and the incidence of CMN was 0.005% (3/57 716). All the cases were male and born through cesarean section due to polyhydramnios for case 1 and 2 and sudden fetal distress, fetal pericardial effusion with enlarged mass in the third trimester for case 3. (2) Prenatal MRI examination found that the lesions in case 1 and 3 were located in the left kidney, and in the right kidney in case 2. The tumors in the three cases were all around with clear borders and hyperintense signal on T2-weighed imaging (T2WI). Iso-signal on T1WI was noted for case 1 and 2, a slightly hypointense signal on T1-weighed imaging (T1WI), and a hyperintense signal on diffused weighed imaging were noted for case 3. (3) Postnatal CT plain scan showed uniform density tumor in cases 1 and 2 with "packing sign" in CT enhancement. Non-uniform density, internal, larger and high-density bleeding tumor was found in case 3, and the CT enhancement manifested as nodular, non-uniform, and intratumoral bleeding. (4) Postoperative pathological examination revealed that cases 1 and 2 were classic types, and case 3 was cellular type.Conclusions:In this study, the prenatal MRI characteristic of CMN is a uniform signal, iso-signal on T1WI for classic type and non-uniform signal, and reduced signal on T1WI for cellular type. In classic type cases, postnatal CT enhancement showed a "packing sign." In contrast, in cellular type cases, the CT plain scan is manifested as non-uniform, intratumoral bleeding, and the enhancement pattern showed nodular and non-uniform enhancement. However, the results of this study is limited due to the small sample size and studies with larger sample size is needed in the future.

ObjectiveTo investigate the effect of macrophages (MCs) on the differentiation of mouse induced pluripotent stem cells (iPSCs) into hepatic progenitor cells (HPCs). MethodsA total of 24 C57BL/6N mice were used to obtain MCs by peritoneal irrigation, and the supernatant was collected to obtain the conditioned medium of MCs (MC-CDM). Activin A, bone morphogenetic protein 4, and fibroblast growth factor were used to induce the differentiation of mouse iPSCs into HPCs. The differentiation of HPCs were randomly divided into control group (normal medium) and experimental group (MC group; use of MC-CDM medium on day 5 of induction). Morphology, immunofluorescence assay, and Western blot were used to compare the morphology of HPCs and the expression of related proteins between the control group and the MC group. The t-test was used for comparison of continuous data between two groups. ResultsHPCs derived from iPSCs were established in vitro, and HPCs had the potential to differentiate into hepatocytes. Immunofluorescence assay showed that compared with the D12 control group, the D12 MC group had a significant increase in the protein expression of the HPC-specific protein CK19 (0.901±0.072 vs 0.686±0.097, t=-3.093, P＜0.05). Western blot showed that compared with the D12 control group, the D12 MC group had a significant increase in the protein expression of the HPC-related protein CK19 (1.922±0.103 vs 1.448±0.012, t =-7.881, P ＜005), as well as a significant increase in the protein expression of the autophagy-related protein LC3 (1.392±0.042 vs 1.101±0048, t =-5.978, P＜005). ConclusionMCs can promote the differentiation of mouse iPSCs into HPCs, possibly by increasing the autophagy level of HPCs.

Objective To evaluate the diagnostic value of MRI-measured fetal percent predicted lung volume (PPLV) for the prognosis of left congenital diaphragmatic hernia (CDH) in fetus. Methods Clinical data of 32 children who were admitted to Women and Children's Medical Center of Guangzhou from September 2012 to December 2017 for prenatally diagnosed left CDH were retrospectively analyzed. These children were divided into two groups, the survival group (n=24) and the death group (n=8), according to the postoperative outcomes at 30 days after CDH repair. Moreover, they were also divided into non-pulmonary hypertension (non-PH) group (n=20) and PH group (n=12), based on whether they suffered from PH or not. Clinical data such as gestational age, birth weight, Apgar score and PPLV values in different groups were compared with t- or Fisher's exact test. The receiver operating characteristic (ROC) curve of the MRI-measured fetal PPLV values of the 32 children was plotted. Results (1) Comparing with the death group, fetal PPLV was significantly higher [(39.5±2.5)% vs (20.4±2.1)%, t=4.27], the gestations on initial diagnosis of CDH was later [(31.6±4.2) vs (25.4±4.6) gestational weeks, t=3.40], Apgar score of the neonates at 5 min was higher (8.7±1.5 vs 5.7±3.8, t=3.26), and fewer cases of PH were reported in the survival group [16.7% (4/24) and 8/8], all P<0.01. The area under the ROC curve of PPLV values for mortality prediction was 0.930 (95%CI: 0.843-1.016, P<0.01). When the PPLV value was 28.55%, its sensitivity and specificity for death prediction in children with left CDH were 100% and 79%, respectively. (2) Comparing with the PH group, fetal PPLV was significantly higher [(41.7±2.6)% vs (23.0±2.0)%, t=4.98], the gestations on initial diagnosis of CDH was later [(32.3±3.4) vs (26.3±5.2) gestational weeks, t=3.81], neonatal Apgar score at 5 min was higher (8.6±1.4 vs 6.8±2.5, t=2.62) and death rate was lower [0(0/20) vs 8/12] in the non-PH group (all P<0.01). The area under the ROC curve of the PPLV values for predicting PH was 0.902 1 (95%CI : 0.800-1.004, P＜0.01). When the PPLV value was 33.67%, its sensitivity and specificity for PH prediction was 100% and 75%, respectively. Conclusions Prenatal MRI measurement of PPLV can be used to predict death or as a warning sign of PH in children with left CDH, which may provide evidence for prenatal evaluation and rational clinical decision-making.

Objective To summarize the experience of perioperative management for repair of congenital diaphragmatic hernia (CDH) supported by extracorporeal membrane oxygenation (ECMO). Method Retrospective review was conducted for the clinical data of CDH patients who received surgical repair on ECMO from December 2016 to June 2018 in Guangzhou Women and Children's Medical Center. Result Four fetus with prenatal diagnosis of left-side CDH were transferred to our Center and received standardized perinatal management. Moderate-severe pulmonary hypoplasia was recognized after evaluation by fetal imaging. Four cases were initiated with veno-arterial ECMO at 3, 35, 41, 11 h of life, respectively. Repair of the diaphragmatic defect was performed within two weeks after cannulation of ECMO. Furthermore, activated clotting time goals were adjusted to 180～220 s, activated partial thromboplastin time were stabilized between 50～80 s, platelets count were maintained>100×109/L and hematocrit was kept>30％before the surgery. The surgeries of four patients were completed on the 0.9th, 0.5th, 3.6th, 5.1th day of life on ECMO, respectively. The defect was repaired by parachute patch. The operative time was 85～210 min. According to CDH Staging System defect size (A to D), there were two with defects at grade C and other two at grade D. Postoperative total volume of drainage was 215～1301 ml and ECMO duration was 3.0～39.3 d. Three of them survived during neonatal period, while one died. Conclusion Repair of CDH on ECMO is feasible and help to improve neonatal survival, especially for those with moderate-severe pulmonary hypoplasia.

Objective To investigate the prenatal imaging features of fetal congenital esophageal atresia and to further evaluate the value of MRI and ultrasound scan in the same condition.Methods This study recruited 12 singleton gravidas whose fetuses were initially suspected with congenital esophageal atresia by prenatal ultrasound scan and then confirmed by surgery and/or upper gastrointestinal angiography after birth at Guangzhou Women and Children's Medical Center from May 2011 to May 2017.Imaging features of prenatal MRI and ultrasonography of the 12 fetuses were retrospectively analyzed.Differences in imaging findings of these two methods were analyzed by Chi-square test.Results All 12 women received prenatal ultrasound examination and eight of them underwent MRI scan when fetal congenital esophageal atresia was suggested by ultrasound.Both ultrasound and MRI were capable of identifing polyhydramnios and absent or small stomach bubble (12/12 and 8/8,respectively).However,MRI was superior to ultrasound in detecting "pouch sign "/"oral filling sign" or poor filling of small intestine (7/8 vs 3/12 and 8/8 vs 0/12,x2 were 7.500 and 20.000,both P＜0.01).While,no statistical difference was shown in detecting curved tracheal between MRI and ultrasound (2/8 vs 0/12,x2=3.333,P=0.067).For Gross Ⅰ or Gross Ⅲ congenital esophageal atresia fetuses,no statistically significant difference was found in their imaging features (all P＞0.05).The total detection rates after 32 weeks of gestation of Gross Ⅰ and Gross Ⅲ cases were both 3/6.Conclusions Prenatal MRI is a vital supplement to ultrasound due to its high display rate of characterized features of congenital esophageal atresia.Thus,the combined use of ultrasound and MRI is of great importance for prenatal diagnosis of this fetal abnormality.

Objective To study the effect of multi-disciplinary team (MDT) management on the outcome in neonates with omphalocele.Method A retrospective non-randomized controlled clinical study was conducted.Neonates who were diagnosed as omphalocele and admitted to the surgical neonatal intensive care unit of the Guangzhou Women and Children Medical Center from December 2010 to December 2017 were collected.Because MDT was established in December 2014,infants were assigned into non-MDT group and MDT group according to their dates of admission.The characteristics and outcomes between non-MDT group and MDT group were compared using x2,t-test or rank-sum test.Multivariate analysis was performed by Logistic regression.Result A total of 91 neonates were included in the study,50 were in non-MDT group and 41 were in MDT group.The mortality in MDT group (2.4％,1/41) was lower than that in non-MDT group (18.0％,9/50),the difference was statistically significant (P ＜ 0.05).The median time of mechanical ventilation of giant omphalocele in non-MDT group (18.3 hours) was longer than that in MDT group (41.7 hours),the difference was also statistically significant (P ＜ 0.05).After adjusting for the associated confounding risk factors,the risk of death in non-MDT group was 54 times higher than that in MDTgroup (OR=54.19,95％CI2.64 ～1 113.49,P＜0.05).Conclusion There was significant association between the MDT management and the decreased risk of death of omphalocele.

This article reported a case of kaposiform lymphangiomatosis (KLA) identified in the fetal stage and diagnosed at the neonatal stage. A routine ultrasound examination at 19 weeks of gestation showed multiple masses in the whole body of the fetus (involving neck, chest wall and armpit) complicated by pleural and peritoneal effusion. Shunting was performed to drain pleural effusion from the right chest in another hospital at 26 +5 weeks of gestation. The patient was born at 34 +3 weeks of gestation by cesarean section due to "intrauterine distress" and required invasive ventilator assisted ventilation support after birth because of respiratory distress. A large amount of hemorrhagic effusion was drained out during the shunting. Coagulation dysfunction and thrombocytopenia occurred on the 3rd day after birth and KLA was suspected. Empirical treatment with sirolimus turned out to be ineffective. Biopsy was taken on postnatal day 7. However, the patient died on the 12th day after birth due to respiratory and circulatory failure. Pathological findings obtained the day after death were consistent with the features of KLA. The diagnosis of KLA was confirmed based on the clinical manifestations and pathological results.
