Recompensation of complications in patients with hepatitis B virus-related decompensated cirrhosis treated with entecavir antiviral therapy / 中华肝脏病杂志

Objective: To analyze the occurrence of recompensation conditions in patients with chronic hepatitis B virus-related decompensated cirrhosis after entecavir antiviral therapy. Methods: Patients with hepatitis B virus-related decompensated cirrhosis with ascites as the initial manifestation were prospectively enrolled. Patients who received entecavir treatment for 120 weeks and were followed up every 24 weeks (including clinical endpoint events, hematological and imaging indicators, and others) were calculated for recompensation rates according to the Baveno VII criteria. Measurement data were compared using the Student t-test or Mann-Whitney U test between groups. Categorical data were compared by the χ (2) test or Fisher's exact probability method between groups. Results: 283 of the 320 enrolled cases completed the 120-week follow-up, and 92.2% (261/283) achieved a virological response (HBV DNA 20 IU/ml). Child-Pugh and MELD scores were significantly improved after treatment (8.33 ± 1.90 vs. 5.77 ± 1.37, t = 12.70, P < 0.001; 13.37 ± 4.44 vs. 10.45 ± 4.58, t = 5.963, P < 0.001). During the 120-week follow-up period, 14 cases died, two received liver transplants, 19 developed hepatocellular cancer, 11 developed gastroesophageal variceal bleeding, and four developed hepatic encephalopathy. 60.4% (171/283) (no decompensation events occurred for 12 months) and 56.2% (159/283) (no decompensation events occurred for 12 months and improved liver function) of the patients had achieved clinical recompensation within 120 weeks. Patients with baseline MELD scores > 15 after active antiviral therapy achieved higher recompensation than patients with baseline MELD scores ≤15 [50/74 (67.6%) vs. 109/209 (52.2%), χ (2) = 5.275, P = 0.029]. Conclusion: Antiviral therapy can significantly improve the prognosis of patients with hepatitis B virus-related decompensated cirrhosis. The majority of patients (56.2%) had achieved recompensation. Patients with severe disease did not have a lower probability of recompensation at baseline than other patients.

Methyl ferulic acid ameliorates ethanol-induced L02 cell steatosis through microRNA-378b-mediated CaMKK2-AMPK pathway / 中国中药杂志

Alcoholic liver disease(ALD), with its increasing morbidity and mortality, has seriously and extensively affected the health of people worldwide. Methyl ferulic acid(MFA) has been proven to significantly inhibit alcohol-induced lipid production in L02 cells through the AMP-activated protein kinase(AMPK) pathway, but its in-depth mechanism remains unclear. This study aimed to further clarify the mechanism of MFA in improving lipid accumulation in L02 cells through the microRNA-378b(miR-378b)-mediated calcium/calmodulin-dependent protein kinase kinase 2(CaMKK2)-AMPK signaling pathway based on existing researches. L02 cells were induced by 100 mmol·L~(-1) ethanol for 48 h to establish the model of ALD in vitro, and 100, 50, and 25 μmol·L~(-1) concentration of MFA was treated. MiR-378b plasmids(containing the overexpression plasmid-miR-378b mimics, silence plasmid-miR-378b inhibitor, and their respective negative control-miR-378b NCs) were transfected into L02 cells by electroporation to up-regulate or down-regulate the levels of miR-378b in L02 cells. The levels of total cholesterol(TC) and triglyceride(TG) in cells were detected by commercial diagnostic kits and automatic biochemical analyzers. The expression levels of miR-378b in L02 cells were detected by real-time quantitative polymerase chain reaction(qRT-PCR). CaMKK2 mRNA levels were detected by PCR, and protein expressions of related factors involved in lipid synthesis, decomposition, and transport in lipid metabolism were detected by Western blot. The results displayed that ethanol significantly increased TG and TC levels in L02 cells, while MFA decreased TG and TC levels. Ethanol up-regulated the miR-378b level, while MFA effectively inhibited the miR-378b level. The overexpression of miR-378b led to lipid accumulation in ethanol-induced L02 cells, while the silence of miR-378b improved the lipid deposition induced by ethanol. MFA activated the CaMKK2-AMPK signaling pathway by lowering miR-378b, thus improving lipid synthesis, decomposition, and transport, which improved lipid deposition in L02 cells. This study shows that MFA improves lipid deposition in L02 cells by regulating the CaMKK2-AMPK pathway through miR-378b.

Simultaneous determination of seven different components in Cynomorium songaricum Rupr. by QAMS / 药学学报

A quantitative analysis of multi-components by single marker method (QAMS) was established for simultaneous determination of gallic acid, protocatechuic acid, catechin, epicatechin, p-coumaric acid, ferulic acid and phloridzin in Cynomorium songaricum Rupr. The analysis was performed on a ChromCore Polae C18 column (250 mm×4.6 mm, 5 μm) , with a mobile phase consisting of acetonitrile-0.3% phosphoric acid aqueous solution for gradient elution. The volume flow rate, column temperature and sample injection volume were set at 1.0 mL·min-1, 25 ℃, and 40 µL, respectively. The relative correction factors of gallic acid and protocatechuic acid, catechin, epicatechin, p-coumaric acid, ferulic acid and phloridzin were calculated and the durability was also investigated. The contents of these seven compounds in fourteen batches of Cynomorium songaricum Rupr. from different producing areas or batches were determined by external standard method (ESM) and quantitative analysis of multi-components with a single-marker method (QAMS), respectively. SPSS and Origin Pro software were employed for principal components assay, similarity evaluation and cluster analysis. The specificity, precision, repeatability, stability and linear range (R2 > 0.999 0) of the seven components were all good. The average recovery was 96.89%-103.16% and RSD was 0.55%-2.76%. Then gallic acid was chosen as internal reference for calculation the correction factors for the other six components, the average relative correction factors of protocatechuic acid, catechin, epicatechin, p-coumaric acid, ferulic acid and phloridzin were 1.141 5, 0.200 5, 0.208 0, 2.361 9, 1.867 7, 0.204 6, respectively. Student's test results showed that there was no significant difference between the data analyzed by ESM and the data obtained from QAMS method. Through data visualization analysis, the contents of gallic acid, protocatechuic acid, catechin and epicatechin in different samples were significantly different, indicating that these four components might be the main quality markers of Cynomorium songaricum Rupr. for gaving more contributes to the principal components. The cluster analysis showed that samples from Xinjiang and samples from Inner Mongolia were clustered in significantly different categories, meaning that the quality of Cynomorium songaricum Rupr. had great relation with producing areas. The method of QAMS established in this study is a simple, economical and practical method with scientific and applicable charactistics for evaluating the quality of Cynomorium songaricum Rupr. efficiently and scientifically.

Objective:To evaluate the relationship between sleep arousal, ambulatory blood pressure and new-onset heart failure(NOHF)in elderly patients with obstructive sleep apnea(OSA).Methods:A total of 584 elderly patients with OSA who were diagnosed and treated in our hospital between March 2015 and March 2019 were prospectively and consecutively selected, with a mean age of(70.1±7.2)years.Polysomnography(PSG)results were obtained at baseline, and the arousal index(AI)was calculated.Based on the quartiles of AI, patients were divided into 4 groups: a low-level group(AI<18.4/h, 186 cases), a low-medium level group(18.4-29.1/h, 177 cases), a medium-high level group(29.2-41.2/h, 137 cases)and a high-level group(>41.2 /h, 84 cases). Participants were followed up for 18 months, the results of ambulatory blood pressure were recorded and compared, and the relationship between AI and the risk of NOHF was analyzed.Results:Compared with the low-level group, patients in the low-medium, medium-high, and high-level groups were older(70.1, 70.3, 73.3 vs.68.7 years, F=2.726, P=0.043)and had more smokers(43.8%, 49.6%, 54.8% vs.38.2%, χ2=8.809, P=0.032), a larger body mass index(26.3, 26.7, 27.6 vs.25.4 kg/m 2, F=2.731, P=0.042), a higher Epworth sleepiness scale score(7.83, 8.50, 9.91 vs.7.64, F=5.124, P=0.018), a higher apnea hypopnea index(23.5, 34.8, 52.7 vs.17.6, F=5.632, P=0.007), lower nocturnal oxygen saturation(80.2, 75.3, 72.1 vs.83.7 mmHg, F=4.811, P=0.024), and higher N-terminal pro-B-type natriuretic peptide(NT-proBNP)levels(317.5, 337.5, 359.2 vs.267.5 pg/L, F=4.307, P=0.033). At the median follow-up(18 months, 14-24 months), the results of ambulatory blood pressure monitoring showed that 24-hour systolic blood pressure(24 h SBP)(147.3, 148.6, 156.2 vs.143.8 mmHg, F=5.4311, P=0.013), 24-hour diastolic blood pressure(24 h DBP)(80.1, 79.5, 83.7 vs.76.5 mmHg, F=5.679, P=0.011)in the low-medium, medium-high and high-level groups were higher than those in the low-level group.The results of survival analysis showed that there were 75(12.8%)cases of NOHF, mostly with preserved ejection fraction(47 cases)or mid-range ejection fraction heart failure(20 cases). The incidences of NOHF were 6.5%, 12.4%, 16.1% and 22.4%, respectively for the low level, low-medium, medium-high and high-level groups, and the risk of NOHF in the low-medium, medium-high and high-level groups was significantly higher than in the low level group(log-rank χ2=11.624, P=0.007). Variables with P<0.2 in the univariate analysis, age and sex were included in the multivariate Cox regression analysis.The results showed that age( HR=1.724, 95% CI: 1.216-3.135), diabetes( HR=1.514, 95% CI: 1.127-3.058), NT proBNP( HR=1.517, 95% CI: 1.232-2.366), nocturnal diastolic blood pressure( HR=2.004, 95% CI: 1.332-4.638), and middle-high AI level( HR=1.611, 95% CI: 1.204-2.967)and high AI level( HR=1.863, 95% CI: 1.272-3.538)were independent factors of NOHF in elderly OSA patients. Conclusions:Sleep arousal in elderly patients with OSA increases blood pressure levels and the risk of NOHF.

Postoperative changes in 25-hydroxy vitamin D and parathyroid hormone levels in obese patients / 中华临床营养杂志

Objective:To investigate the postoperative changes in levels of 25-hydroxy vitamin D (25-[OH]D], parathyroid hormone (PTH) and other relevant biomarkers in obese patients receiving metabolic surgery and analyze the dynamic changes in relevant biomarkers in the short term (after 3-6 months) and the long term (after 12-24 months).Methods:A total of 96 obese patients who underwent metabolic surgery and received follow-up examinations from January 2018 to January 2020 were included. Baseline and postoperative data were collected, including anthropometric data (height, weight, neck circumference, waistline and hipline) and laboratory test results (fasting glucose, glycated hemoglobin, 25-[OH)D, PTH, serum calcium and serum phosphorus). Body mass index (BMI) and waist-hip ratio were calculated. The anthropometric data were analyzed by repeated measures analysis of variance and laboratory data were compared between groups using t test and Kruskal-Wallis test. Results:96 patients (33 males and 63 females) were included, of whom 49 were complicated with diabetes. Prior to surgery, 79 (79.17%) of the patients had 25-(OH)D deficiency (< 20 μg/L), 16 (16.67%) had 25-(OH)D insufficiency (≥ 20 μg/L and < 30 μg/L) and 23 (23.96%) had high PTH levels (> 70 ng/L). After the surgery, 25-(OH)D level was transiently increased in the short term ( P = 0.01) but declined thereafter in the long term ( P < 0.01) to levels lower than baseline ( P = 0.023). Long-term PTH level was higher than baseline ( P = 0.012), with 11 patients showing PTH levels higher than normal (> 70 ng/L). Serum phosphorus level was increased in both the short term and the long term ( P < 0.01). Conclusions:Obese patients have 25-(OH)D deficiency/insufficiency before metabolic surgery and experience further decrease in the long term after surgery, despite a transient increase. Secondary increase in PTH level occurs in some of the patients after surgery. Long-term nutritional supplements and comprehensive nutritional management play important roles in postoperative management of obese patient.

Association of weight loss with diabetes remission after metabolic surgery in patients with type 2 diabetes for 10 years and above / 中华临床营养杂志

Objective:To explore the association of weight loss with diabetes remission after metabolic surgery in patients with type 2 diabetes mellitus(T2DM) for 10 years and more.Methods:Data of T2DM patients with obesity who underwent metabolic surgery in the General Surgery Department & Obesity and Metabolic Disease Center of China-Japan Friendship Hospital from November 2017 to June 2021 were retrospectively collected and analyzed. Remission of diabetes was defined as glycated hemoglobin (HbA1c) < 6.5% or fasting blood glucose < 7.0 mmol/L after discontinuing anti-diabetic medication for more than 3 months. The patients were followed up and divided into two groups according to whether the percentage total weight loss (%TWL) was ≥ 20% or not. The age, sex, body mass index (BMI), fasting C-peptide, and HBA1c were compared between the two groups.Results:Among 65 (28 males and 37 females) patients with T2DM for ≥ 10 years , 50 (76.9%) achieved diabetes remission after a median of 12-month follow-up. 6.2%, 41.5% , 38.5% and 13.8% of the patients achieved %TWL < 10%, 10~20%, 20~30% and ≥ 30% , respectively. The diabetes remission rates were 50%, 63.0%, 92.0% and 88.9%, respectively. Compared with the %TWL < 20% group, the preoperative weight [(95.5±18.8) kg vs (85.5±11.0) kg, P = 0.012] and BMI [(34.4±6.0) vs (30.9±3.3) , P = 0.006] were significantly higher in the %TWL ≥ 20% group, and diabetes remission rates was aslo significantly higher in the %TWL ≥ 20% group (91.2% vs 61.3%, P = 0.010) . After adjusting for age, preoperative BMI, fasting C-peptide and duration of T2DM, Cox multivariate regression analysis showed that %TWL ≥ 20% was independently associated with diabetic remission after metabolic surgery in patients with T2DM for ≥ 10 years (HR = 1.99, 95% CI: 1.03 to 3.83, P = 0.04). Conclusions:More than 70% of patients with T2DM for ≥ 10 years could achieve diabetes remission after metabolic surgery. %TWL ≥ 20% may be one independent factor of diabetes remission in patients with long-duration T2DM.

The clinical application and development of traditional antitumor drugs / 药学学报

Traditional antitumor drugs are cytotoxic chemotherapeutic drugs that can directly kill tumor cells and inhibit the growth and proliferation of tumor cells. Modern chemotherapy for tumors was initiated by use of nitrogen mustard to treat lymphomas in 1946, which was derived from mustard gas. Starting with nitrogen mustard, many kinds of anti-tumor drugs, including alkylating agents, anti-metabolism drugs, anti-tumor antibiotics, and anti-tumor plant drugs, have been successively developed for clinical treatment. Traditional antitumor drugs are the cornerstone of tumor chemotherapy and play important roles in the comprehensive treatment and neoadjuvant therapy of malignant tumors. In recent years, the combination of traditional antitumor drugs with molecular targeted therapy, immunotherapy, and radiotherapy has greatly improved the survival rate of tumor patients. With the deepening understanding of tumor genome as well as tumor initiation and promotion, the concepts of precision medicine and individualized treatment have been proposed and achieved success in clinical practice. In this context, the strategies leading to personalized therapy with traditional anti-tumor drugs also need to be further studied and optimized. This review summarized the recent clinical application and research progress of traditional antitumor drugs.

Research progress in multi-targeted anti-tumor natural products / 药学学报

Natural products and their derivatives are important components of anti-tumor drugs. Currently, anti-tumor drugs derived from natural products which are in clinical practice are mainly conventional cytotoxic or molecularly targeted drugs. Their application is limited by drug-related side effects and drug resistance. Recent studies have shown that anti-tumor natural products often act on multiple targets in tumor cells and in turn interfere with multiple processes in tumorigenesis and development. As tumor is a systemic disease induced by multiple factors, multi-targeted natural products possess unique potential in tumor therapy. However, the targets and mechanisms of the discovered multi-targeted antitumor natural products remain elusive, which limits their further development and application. This review summarized the research progress in the mechanism of action, target identification, and structure optimization of multi-targeted anti-tumor natural products exemplified by a few typical compounds. The research and development of these agents have also been proposed.

The value of microvascular flow imaging method for the evaluation of placenta perfusion and prediction of fetal growth restriction: a pilot study / 中华超声影像学杂志

Objective:To evaluate the placental micro-vascular circulation by microvascular flowing imaging (MVFI) method, and to explore the clinical value of microvascular index (MVI) for the diagnosis of fetal growth restriction (FGR).Methods:A total of 21 fetuses at 24-34 weeks of gestation at the Peking Union Medical College Hospital from October to November 2019 were enrolled in this study, including 7 fetal growth restriction (FGR) fetuses, and 14 normal fetuses as control group. The fetuses of the two groups were matched according to the gestational weeks at the ratio of 1∶2. Fetal biometry parameters were measured and the placenta was observed by two-dimensional ultrasound.Uterine artery pulse index (UtA-PI), middle cerebral artery pulse index (MCA-PI), and umbilical artery S/D ratio were evaluated by color and pulse-wave Doppler. The placenta mico-circulation was displayed by the MVFI method and MVI was measured.Results:The study included 14 normal fetuses and 7 FGR fetuses. Compared with the control group, more placenta in the FGR group manifested as thickened and heterogeneous with decreased MVI and increased UtA-PI. There was statistically significant difference in placental mean MVI between two groups ( P=0.044). Besides, a trend towards significant negative correlation was observed between MVI and placenta thickness, although this was not statistically significant ( rs=-0.35, P=0.065). MVI had a higher specificity (100%) in the prediction of FGR. Conclusions:MVFI can display the micro-circulation of the placenta, and provide a direct and quantitative assessment method for placental perfusion.

Progress in molecularly targeted anti-tumor drugs derived from natural products or their derivatives / 药学学报

Conventional chemotherapy drugs, molecularly targeted drugs, and immune checkpoint inhibitors are the major constituents of anti-tumor drugs in clinical settings at present. Molecularly targeted drugs specifically target the key proteins, genes, or signal transduction pathways in tumor cells which are essential for initiation and development of tumor, resulting in selective activity to induce cell death or growth inhibition. Molecularly targeted drugs have emerged as the mainstream in the research and development of anti-tumor drugs due to its high selectivity and low toxicity. Natural products refer to the chemical constituents or metabolites originated animals, plants, or microorganisms, which have been recognized as one of the important sources of drug discovery with abundant resources and diversified structures. At present, a number of molecularly targeted anti-tumor drugs derived from natural products or their derivatives have been approved for cancer therapy or in clinical trials. This review will summarize the molecularly targeted anti-tumor drugs derived from natural products or their derivatives according to their different cellular targets, and also outline the molecular mechanism, progress, and perspectives of these drugs.

Objective To investigate the prenatal diagnosis and genetic counseling of fetal nuchal fold (NF) thickening.Methods This study retrospectively analyzed 17 fetuses with increased NF detected by prenatal ultrasound examination in Peking Union Medical College Hospital,Peking Union Medical College & Chinese Academy of Medical Sciences from December 1,2016 to December 1,2017.All cases were divided into isolated (isolated group) or non-isolated increased NF group (non-isolated group) according to whether the fetus had concomitant ultrasonographic abnormalities or not.Karyotype and chromosomal microarray analysis (CMA) were performed on all cases.Clinical data,prenatal genetic testing results and pregnancy outcomes were analyzed.Results Of those twelve cases in the isolated group,two were terminated due to the identification of chromosomal abnormalities and pathogenic copy number variations (CNVs) and the fetal autopsy results were consistent with the prenatal diagnosis.The rest 10 pregnancies were all continued including one fetus carrying a variant of unknown significance,which was proved to be a paternal heredity by CMA,and nine without genetic abnormalities and all-these infants were healthy during follow-up.Among the five non-isolated cases,one was diagnosed as trisomy 21 by karyotyping and CMA,and the other four were found to have structural abnormalities under ultrasound scan,but without genetic abnormalities in karyotyping and CMA.And all the five pregnancies were terminated after genetic counseling and three of them chose whole exome sequencing (WES) for further test.One homozygous mutation in CHRNA 1 gene and one de novo mutation in SETD2 gene were found in two cases,respectively,while no abnormality was identified in the other one case.Conclusions Once increased NF were indicated by ultrasound examination,prenatal genetic testing should be offered to the patients,including CMA,regardless of other ultrasonographic abnormalities,and WES should also be offered when necessary.Considering a thickened NF is associated with increased risks of structural defects,a close follow-up with fetal echocardiography and ultrasound is required even the prenatal tests are normal.

Early sonographic diagnosis of amniotic band syndrome at 11－14 weeks′gestation / 中华超声影像学杂志

To investigate the prenatal sonographic feature in the early diagnosis of amniotic band syndrome at 11 －14 weeks′ gestation . Methods A retrospective study was conducted to analysis and summarize the ultrasonographic features of 4 fetuses without band‐like echoes in amniotic cavity at 11－14 weeks′gestation ,but verified as amniotic band syndrome in Peking Union M edical College Hospital . Results T wo cases ( cases 1 ,2) showed the fixed head position with skull defect and intracranial structure disorders . Cases 3 and 4 showed one upper limb in a fixed position ,and the hand seemed to adhere to the umbilical cord isolatedly . In addition ,case 1 showed complete chorioamniotic membrane separation . T here were multiple band‐like echoes adhered to body of 3 fetals during the follow‐up scan at 14 －18 weeks . T he parents of cases 1 and 2 chose to terminate the pregnancy after counseling ,the other 2 cases also induced labor due to intrauterine fetal death at 15+2 weeks and 19+2 weeks respectively . All 4 cases were confirmed as amniotic band syndrome by pathology . Conclusions When the fetal sonographic images showed fixed head position ,disordered intracranial structure ,or adhesion between umbilical cord and hand with limited movement at 11 －14 weeks′ gestation ,it should be paid attention to observing the band‐like echoes and followed up closely to prevent missed diagnosis of amniotic band syndrome .

Correlation and regression analysis of fetal facial angles at 11－38 weeks of pregnancy with gestational age / 中华超声影像学杂志

Objective To determine the fetal facial angles at 11 －38 weeks of gestation by three‐dimensional ultrasound ( 3DUS) and analyze the correlation between facial angles and gestational age( GA ) . Methods From 2013 April to 2014 February ,439 singleton fetuses ranged 11－38 weeks of gestation were enrolled in this study . T he details of mid‐sagittal plane of facial profile was confirmed with 3DUS . Four facial angels were measured in this plane ,including frontomaxillary facial angle ( FM F ) ,frontonasal angle ( FNA ) ,mandibulomaxillary facial angle( M M F) and maxilla‐nasion‐mandible angle( M NM ) . T he intra‐and interobserver reliability were calculated in first 30 cases ,intra‐class correlation coefficient( ICC) greater than 0 .75 indicated good reliability . Pearson′s correlation coefficient ( r ) ,curve estimation and polynomial regression models were used to evaluate the correlation of the fetal facial angles with GA . Results ICC of the same observer were 0 .968 ,0 .962 ,0 .974 and 0 .988 ,respectively . ICC of different observer were 0 .948 , 0 .905 ,0 .874 and 0 .889 ,respectively . T he fetal facial angles of FM F ,FNA ,M M F and M NM showed correlations with GA ( r ＝ －0 .369 ,0 .447 ,－0 .470 ,0 .386 ; all P ＝0 .000) . Using GA as the independent variable and the facial angles as the dependent variables , the best fit regressing equation was cubic polynomial :FM F＝135 .300－6 .473×GA+0 .235×GA2 －0 .003×GA3 ( R2 ＝0 .240 , P ＝0 .000 ) ;FNA＝58 .920+7 .452×GA －0 .274×GA2 －0 .003×GA3 ( R2 ＝0 .297 , P ＝0 .000 ) ;M M F＝132 .329 －5 .337× GA+0 .191× GA2 －0 .002× GA3 ( R2 ＝ 0 .304 , P ＝ 0 .000) ;M NM ＝ －24 .592+ 4 .653× GA －0 .173× GA2 + 0 .002 × GA3 ( R2 ＝ 0 .413 , P ＝ 0 .000 ) . Conclusions The development of fetal facial angles are related to GA . T he growing patterns of fetal facial angles fit with a cubic polynomial function .

Prenatal ultrasonic diagnosis and outcome of congenital dacryocystocele / 中华超声影像学杂志

Objective@#To explore the value of prenatal ultrasound in diagnosis of congenital dacryocystocele.@*Methods@#The ultrasonographic features of 16 fetuses with congenital dacryocystocele were retrospectively reviewed and the outcome of pregnancy were followed up.@*Results@#The median gestational week detected with prenatal ultrasound was 30.29 weeks, the mean diameter was (8.96±1.96)mm. Congenital dacryocystoceles were unilateral in 12 fetuses and bilateral in 4 fetuses, 10 were female and 6 were male. The typical ultrasonic feature was anechoic cystic mass with clear boundary in relation to the medial and inferior aspects of the fetal orbit. The dacryocystocele resolved spontaneously prenatally in 5 fetuses, resolved spontaneously after delivery in 10 fetuses. One fetus died in caesarean section due to complete placenta previa.@*Conclusions@#Congenital dacryocystitis has its characteristic ultrasonographic features, and most cases can disappear naturally in prenatal or early newborns.
