RESUMEN
BACKGROUND AND PURPOSE: abdominal tuberculosis (TB) is a common form of extrapulmonary TB but it is still a diagnostic dilemma in clinical practice. This study aimed to highlight the clinical features and diagnostic approaches for abdominal TB. METHODS: seventy cases of diagnosed abdominal TB were retrospectively collected between August 1st, 2015 and June 30th, 2020. They were classified as peritoneal TB, lymph node TB, gastrointestinal TB, visceral TB or mixed TB. RESULTS: eighteen patients were diagnosed with peritoneal TB, nine with lymph node TB, five with gastrointestinal TB, two with visceral TB and 36 with mixed TB. More than 65 % of the patients had tuberculosis of other sites except the abdomen. The median diagnosis time was 60 days. Ascites (58.6 %), abdominal distension (48.6 %), weight loss (44.3 %) and fever (42.9 %) were the most common symptoms. The overall microbiological and histological detection rates were 70.0 % and 38.6 %, respectively. The non-ascite samples yielded a higher microbiological confirmation rate (63.6 %) than the total samples (40.8 %). Diagnosis was confirmed histologically in 18 patients (69.2 %). Forty-five cases (64.3 %) were clinically diagnosed. Invasive procedures such as surgery (6/7), percutaneous biopsy (7/7) and endoscopy in lymph node TB (4/5) had high confirmation rates. CONCLUSIONS: the diagnosis of abdominal TB should be reached by a combination of clinical, laboratory, radiological, microbiological and pathological findings.

This paper reports the diagnosis and treatment of a pregnant woman complicated with myotonic dystrophy (DM) type 1(DM1). The pregnant woman complained of occasional dull pain in the precardiac region accompanied by night sweats in the first trimester and a mild increase in myocardial enzymes was observed. Symptoms were improved after oral medication followed by no regular reexamination. While in the third trimester, abnormal myocardial enzyme, liver enzyme, and urinary protein were found and echocardiography and abdomen ultrasound suggested multiple organic lesions involving the heart and spleen. A girl was born through cesarean section at 36 +5 weeks of gestation due to maternal heart failure, with Apgar scores of 10 at 1 and 5 minutes. The patient developed acute respiratory failure, ventricular bigeminy, and diarrhea after surgery. Neurology consultation found incomplete buried eyelids in both eyes, weak bulging cheeks, and weak upper extremity muscle strength. Muscle biopsy confirmed the diagnosis of DM and genetic testing showed abnormal amplification of non-coding region [CTG] n in myotonic dystrophy protein kinase gene in chromosome 19q13.3, which indicated DM1. The mother recovered well at nine months postpartum. Further genetic analysis of pedigree and offspring is recommended.

BACKGROUND@#Massive bleeding is the main concern for the management of placenta percreta (PP). Intra-abdominal aortic balloon occlusion (IABO) is one method for pelvic devascularization, but the efficacy of IABO is uncertain. This study aims to investigate the outcomes of IABO in PP patients.@*METHODS@#We retrospectively reviewed the clinical data of PP cases from six tertiary centers in China between January 2011 and December 2015. PP cases with/without the use of IABO were analyzed. Propensity score matching analysis was performed to reduce the effect of selection bias. Postpartum hemorrhage (PPH) and the rate of hysterectomy, as well as neonatal outcomes, were analyzed.@*RESULTS@#One hundred and thirty-two matched pairs of patients were included in the final analysis. Compared with the control group, maternal outcomes, including PPH (68.9% vs. 87.9%, χ2 = 13.984, P < 0.001), hysterectomy (8.3% vs. 65.2%, χ2 = 91.672, P < 0.001), and repeated surgery (1.5% vs. 12.1%, χ2 = 11.686, P = 0.001) were significantly reduced in the IABO group. For neonatal outcomes, Apgar scores at 1 minute (8.67 ± 1.79 vs. 8.53 ± 1.68, t = -0.638, P = 0.947) and 5 minutes (9.43 ± 1.55 vs. 9.53 ± 1.26, t = 0.566, P = 0.293) were not significantly different between the two groups.@*CONCLUSIONS@#IABO can significantly reduce blood loss, hysterectomies, and repeated surgeries. This procedure has not shown harmful effects on neonatal outcomes.

Objective:To explore the effects of interpregnancy interval (IPI) on pregnancy outcomes of subsequent pregnancy.Methods:A multicenter retrospective study was conducted in 21 hospitals in China. Information of age, height, pre-pregnancy weight, IPI, history of diseases, complications of pregnancy, gestational age of delivery, delivery mode, and pregnancy outcomes of the participants were collected by consulting medical records of pregnant women who had two consecutive deliveries in the same hospital during 2011 to 2018. The participants were divided into 4 groups according to IPI:<18 months, 18-23 months, 24-59 months and ≥60 months. According to the WHO′s recommendation, with the IPI of 24-59 months group as a reference, to the effects of IPI on pregnancy outcomes of subsequent pregnancy were analyzed. Stratified analysis was further carried out based on age, history of gestational diabetes mellitus (GDM), macrosomia, and premature delivery, to explore the differences in the effects of IPI on pregnancy outcomes among women with different characteristics.Results:A total of 8 026 women were included in this study. There were 423, 623, 5 512 and 1 468 participants in <18 months group, 18-23 months group, 24-59 months group and ≥60 months group, respectively. (1) The age, pre-pregnancy body mass index (BMI), history of cesarean section, GDM, gestational hypertension and cesarean section delivery rate of <18 months group, 18-23 months group, 24-59 months group and ≥60 months group were gradually increased, and the differences were statistically significant ( P<0.05). (2) After adjusting for potential confounding factors, compared with women in the IPI of 24-59 months group, the risk of premature delivery, premature rupture of membranes, and oligohydramnios were increased by 42% ( OR=1.42, 95% CI: 1.07-1.88, P=0.015), 46% ( OR=1.46, 95% CI: 1.13-1.88, P=0.004), and 64% ( OR=1.64, 95% CI: 1.13-2.38, P=0.009) respectively for women in the IPI≥60 months group. No effects of IPI on other pregnancy outcomes were found in this study ( P>0.05). (3) After stratified by age and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of oligohydramnios for women with advanced age ( OR=2.87, 95% CI: 1.41-5.83, P=0.004); and <18 months could increase the risk of premature rupture of membranes for women under the age of 35 ( OR=1.59, 95% CI: 1.04-2.43, P=0.032). Both the risk of premature rupture of membranes ( OR=1.58, 95% CI: 1.18-2.13, P=0.002) and premature delivery ( OR=1.52, 95% CI: 1.07-2.17, P=0.020) were significantly increased in the IPI≥60 months group. After stratified by history of GDM and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would lead to an increased risk of postpartum hemorrhage for women with a history of GDM ( OR=5.34, 95% CI: 1.45-19.70, P=0.012) and an increased risk of premature rupture of membranes for women without a history of GDM ( OR=1.44, 95% CI: 1.10-1.90, P=0.009). After stratified by history of macrosomia and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months could increase the proportion of cesarean section for women with a history of macrosomia ( OR=4.11, 95% CI: 1.18-14.27, P=0.026) and the risk of premature rupture of membranes for women without a history of macrosomia ( OR=1.46, 95% CI: 1.12-1.89, P=0.005). After stratified by history of premature delivery and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of premature rupture of membranes for women without a history of premature delivery ( OR=1.47, 95% CI: 1.13-1.92, P=0.004). Conclusions:Both IPI≥60 months and <18 months would increase the risk of adverse pregnancy outcomes in the subsequent pregnancy. Healthcare education and consultation should be conducted for women of reproductive age to maintain an appropriate IPI when they plan to pregnant again, to reduce the risk of adverse pregnancy outcomes in the subsequent pregnancy.
RESUMEN
Objective To evaluate the risk factors and sonographic findings of pregnancies complicated by placenta increta or placenta percreta. Methods Totally, 2219 cases were retrospectively analyzed from 20 tertiary hospitals in China from January 2011 to December 2015. The data were collected based on the original case records. All cases were divided into two groups, the placenta increta (PI) group (79.1%, 1755/2219) and the placenta percreta (PP) group (20.9%, 464/2219), according to the degree of placental implantation. The risk factors and sonographic findings of placenta increta or percreta were analyzed by uni-factor and logistic regression statistic methods. Results The risk factors associated with the degree of placental implantation were age, gravida, previous abortion or miscarriage, previous cesarean sections, and placenta previa (all P<0.05), especially, previous cesarean sections (χ2=157.961) and placenta previa (χ2=91.759). Sonographic findings could be used to predict the degree of placental invasion especially the boundaries between placenta and uterine serosa, the boundary between placenta and myometrium, the disruption of the placental-uterine wall interface and loss of the normal retroplacental hypoechoic zone(all P<0.01). Conclusions Previous cesarean sections and placenta previa are the main independent risk factors associated with the degree of placenta implantation. Ultrasound could be used to make a prenatal suggestive diagnosis of placenta accreta spectrum disorders.

Objective To investigate the correlation between TIP 30 and VEGF-C expression and clini-cophathological characteristics in resected small cell lung cancer ( SCLC) patients and to identify patients with in-creased risk of cancer recurrence and to provide a theoretical basis for the further clinical prevention of SCLC . Methods Sixty eight resected SCLC patients were included in this study .Paraffin-embedded specimens of pa-tients were used for the evaluation of TIP 30 and VEGF-C expression by immunohistochemistry .Results The expression of VEGF-C had positive correlation with lymph node metastasis .TIP30 expression was positively cor-related with VEGF-C expression.Patients with low TIP30 expression had shorter Overall survival (OS)and Dis-ease-Free survival(DFS)than those with high TIP30 expression.OS and DFS of the patients with VEGF -C-positive tumors were significantly lower than that of the patients with VEGF -C negative tumors .The multivariate Cox regression analysis showed that low TIP 30 and high VEGF-C expression were independent markers of poor OS(P<0.01)in operable SCLC patients.Conclusion The expression of VEGF -C shows positive correlation with lymph node metastasis .Low TIP30 and high VEGF -C expression are independent prognostic markers of poor overall survival in resected SCLC patients .
RESUMEN
Objective To investigate the expression of interleukin-37 (IL-37) in placenta tissue and its relationship with the pathogenesis of severe preeclampsia. Methods All the patients were recruited in Qilu Hospital of Shangdong University from November 2012 to November 2013. Among them, thirty patients with severe preeclampsia were assigned to the preeclampsia group, and thirty-one healthy pregnant women were assigned to the control group. Immunohistochemistry of SP was used to detect the IL-37 protein expression in placenta tissue of the two groups. The expression level of IL-37 in placenta tissue of the two groups was detected by western blot. Besides, reverse transcription(RT)-PCR was used to detect the expression of IL-37 mRNA. The correlation between the expression of IL-37 mRNA and the delivery gestational age, body mass index(BMI)was analyzed. Results (1) IL-37 were detected in the placenta of both the preeclampsia group and the control group, and the expression site mainly located in the syncytiotrophoblast, with a small amount in cytotrophoblast.(2)The expression levels of IL-37 protein in the preeclampsia group and the control group were 0.59 ± 0.39 and 0.88 ± 0.22, respectively. The IL-37 mRNA levels in the preeclampsia group and the control group were 0.55 ± 0.17 and 1.11 ± 0.21, respectively. Both decreased significantly when compared to the control group (P0.05) was seen neither in the preeclampsia group nor in the control group(r=-0.053, P>0.05). In the severe preeclampsia group, the pregnant women′s BMI had no significant correlation with IL-37 mRNA expression of placenta tissue(r=0.102, P>0.05), neither did the control group(r=-0.115, P>0.05). Conclusion IL-37 expression is significantly lower in severe preeclampsia placenta tissue than that in the normal pregnant women, which may play a protective role in the course of severe preeclampsia.
RESUMEN
Objective To investigate the expression of growth arrest-specific protein 6 (Gas6) in the placenta and decidua tissues and its relationship with the pathogenesis of preeclampsia. Methods All the patients were recruited in Qilu Hospital of Shangdong University from October 2013 to June 2014. Among them, thirty-two women with early-onset severe preeclampsia who received cesarean section were assigned to the preeclampsia group, and thirty healthy pregnant women who received cesarean section were defined as the control group. Blood glucose, blood lipids, platelet count, D-dimer levels and other clinical indicators of the two groups were detected. Immunohistochemistry of SP was conducted to identify the localization of Gas6 protein in the placenta and decidua tissues. And reverse transcription (RT)-PCR was performed for quantitative analysis of Gas6 RNA expression in placentas. The correlations between placental Gas6 mRNA levels with clinical indicators were analyzed. Results (1) The gestational age at delivery, blood pressure, serum albumin, platelet count and birth weight of fetuses showed statistically significant differences between the two groups(P<0.05). (2) The Gas6 protein expressed in the cytoplasm and nucleus of the syncytiotrophoblasts and decidual cells in the placenta and decidual tissues of the two groups. (3) The Gas6 mRNA expression elevated significantly in the placenta of preeclampsia group (0.60 ± 0.38) when compared to that of the control group (0.34±0.22;P<0.05). (4) The expression of Gas6 mRNA was positively related with body mass index, diastolic blood pressure, systolic blood pressure, free fatty acids and creatinine (P<0.05), while it was negatively associated with serum albumin(P<0.05). Conclusion The high expression of Gas6 in the placenta and decidua tissues may be related to the pathogenesis of severe preeclampsia.

RESUMEN
Objective To explore the possibility of breast feeding in chronic asymptomatic hepatitis B virus (HBV) carriers after immuno prophylaxis of the infants. Methods The infants with asymptomatic HBV carriers mothers were selected by the obstetric department of Qilu Hospital of Shangdong University, Jinan Maternity and Infant Health Institute of Shangdong from Sept 2001 to Oct 2003 prospectively. Umbilical blood HBV deoxyribonucleic acid (HBV DNA) was detected at birth. All infants received 200 IU HBV specific immunoglobin(HBIG)within 12 hours and on 14 days after birth. The hepatitis B recombinant vaccine was given within 24 hours after birth and at 1 and 6 months of age. The way of feeding was chosen by the mothers as they liked. There were 55 infants in breast feeding group and 36 in bottle feeding group. Infants were then followed up at 7 and 12 months of age and tested for hepatitis B surface antigen(HBsAg), hepatitis B surface antibody (anti HBs), hepatitis B e antigen(HBeAg), hepatitis B e antibody(anti HBe) and hepatitis B core antibody(anti HBc) and HBV DNA. Uninfected infants with negative anti HBs were given repeated dose of vaccinations. Results At 7 and 12 months of age, the positive rates of HBV DNA were 9.09%(5/55)and 9.09%(5/55), anti HBs were 85.45%(47/55)and 90.90%(50/55)in breast feeding group respectively;while the positive rates of HBV DNA were 8.33%(3/36)and 8.33%(3/36), anti HBs were 86.11%(31/36)and 91.67%(33/36)in bottle feeding group respectively. No significant differences was shown in positive rates of HBV DNA and anti HBs between these two groups. Conclusions With appropriate immunoprophylaxis, including hepatitis B immune globulin and hepatitis B vaccine, HBV carriers can breast feed their babies.
