ABSTRACT

Objective:To study the risk factors of surgical therapy in neonates with necrotizing enterocolitis (NEC).Methods:From January 2016 to July 2020, neonates with a confirmed diagnosis of NEC (Bell's Stage Ⅱ and above) admitted to our hospital were retrospectively enrolled. They were assigned into surgical group and conservative group according to whether surgeries were performed. The conditions during perinatal period, clinical characteristics and laboratory examinations at the onset of NEC were compared between the two groups. Multivariate Logistic regression analysis was used to determine the risk factors of surgical therapy.Results:A total of 177 neonates with NEC were identified, including 62 cases (35.0%) in the surgical group and 115 cases (65.0%) in the conservative group. Multivariate Logistic regression analysis showed that male gender ( OR=3.178,95% CI 1.457~6.929, P=0.004), comorbidity with shock ( OR=3.434, 95% CI 1.112~10.607, P=0.032), mechanical ventilation>7 d before NEC onset ( OR=3.663, 95% CI 1.098~12.223, P=0.035) and lymphocytes <2.0×10 9/L ( OR=4.121, 95% CI 1.801~9.430, P=0.001) at the onset of NEC were independent risk factors for surgical therapy. Conclusions:Male gender, comorbidity with shock, mechanical ventilation >7 d before NEC and lymphocytopenia at the onset are independent risk factors for surgical therapy in neonates with NEC (Stage Ⅱ and above).

ABSTRACT

Objective:To investigate the effects of Tiaogan Lifei Decoction on the level of symptom control in patients with bronchial asthma (asthma) treated with moderate and high dosage inhaled glucocorticoids (ICS).Methods:Randomized double-blind placebo controlled prospective study was used. Totally 90 patients with asthma (liver lung disharmony, wind phlegm blocking collateral syndrome) using moderate and high dosage ICS who met the inclusion criteria from January 2020 to December 2021 in Chaoyang District Hospital of Traditional Chinese Medicine in Beijing were divided into two groups according to random number table method, with 45 cases in each group. On the basis of using the original dosage of ICS, the treatment group used Tiaogan Lifei Decoction, while the control group used Tiaogan Lifei Decoction simulant. The course of treatment was 12 weeks. TCM symptom score of both group before and after the treatment was detected; asthma control test (ACT) was used to assess the effects of asthma on the patients; St George's Hospital Respiratory Questionnaire (SGRQ) was used to assess patients' quality of life; the peak expiratory flow rate (PEF) was measured with a peak expiratory flow meter. 2 ml of venous blood was collected for eosinophil (EOS) detection, and the serum allergen specific IgE level was determined by ELISA. The adverse reactions were observed during the treatment and the clinical efficacy was evaluated.Results:During the test, 3 cases and 2 cases in the treatment group and control group lost prevention respectively. 3 cases in the treatment group and 6 cases in the control group withdrew from the trial because of the aggravation of symptoms and the need to increase the dosage of ICS. The total effective rate in the treatment group was 78.6% (33/42), and that in the control group was 55.8% (24/43), with statistical significance ( χ2=4.98, P=0.026). After treatment, the scores of daily activities, early awakening, control and total scores in the treatment group were higher than those in the control group ( t values were 1.76, 1.99, 2.00, 2.69, respectively, P<0.01 or P<0.05); after treatment, the scores of cough, chest tightness, active wheezing, upset, pharyngeal itch and total score in the treatment group were lower than those in the control group ( t values were -5.89, -6.01, -5.66, -4.27, -6.67, -9.05, respectively, P<0.01); SGRQ score in the treatment group was lower than that of the control group ( t=-7.19, P<0.01). No serious adverse reactions occurred during treatment in the two groups. Conclusion:Tiaogan Lifei Decoction is helpful to improve the symptom control level of asthma patients who are using ICS, and effectively improve the quality of life of patients with asthma of liver lung disharmony and wind phlegm obstructing collaterals syndrome.

ABSTRACT

Objective: To investigate anatomical morphology and classification of persistent descending mesocolon (PDM) in patients with left-sided colorectal cancer, as well as the safety of laparoscopic radical surgery for these patients. Methods: This is a descriptive study of case series. Relevant clinical data of 995 patients with left colon and rectal cancer who had undergone radical surgery in Fujian Medical University Union Hospital from July 2021 to September 2022 were extracted from the colorectal surgery database of our institution and retrospectively analyzed. Twenty-four (2.4%) were identified as PDM and their imaging data and intra-operative videos were reviewed. We determined the distribution and morphology of the descending colon and mesocolon, and evaluated the feasibility and complications of laparoscopic surgery. We classified PDM according to its anatomical characteristics as follows: Type 0: PDM combined with malrotation of the midgut or persistent ascending mesocolon; Type 1: unfixed mesocolon at the junction between transverse and descending colon; Type 2: PDM with descending colon shifted medially (Type 2A) or to the right side (Type 2B) of the abdominal aorta at the level of the origin of the inferior mesentery artery (IMA); and Type 3: the mesocolon of the descending-sigmoid junction unfixed and the descending colon shifted medially and caudally to the origin of IMA. Results: The diagnosis of PDM was determined based on preoperative imaging findings in 9 of the 24 patients (37.5%) with left-sided colorectal cancer, while the remaining diagnoses were made during intraoperative assessment. Among 24 patients, 22 were male and 2 were female. The mean age was (63±9) years. We classified PDM as follows: Type 0 accounted for 4.2% (1/24); Type 1 for 8.3% (2/24); Types 2A and 2B for 37.5% (9/24) and 25.0% (6/24), respectively; and Type 3 accounted for 25.0% (6/24). All patients with PDM had adhesions of the mesocolon that required adhesiolysis. Additionally, 20 (83.3%) of them had adhesions between the mesentery of the ileum and colon. Twelve patients (50.0%) required mobilization of the splenic flexure. The inferior mesenteric artery branches had a common trunk in 14 patients (58.3%). Twenty-four patients underwent D3 surgery without conversion to laparotomy; the origin of the IMA being preserved in 22 (91.7%) of them. Proximal colon ischemia occurred intraoperatively in two patients (8.3%) who had undergone high ligation at the origin of the IMA. One of these patients had a juxta-anal low rectal cancer and underwent intersphincteric abdominoperineal resection because of poor preoperative anal function. Laparoscopic subtotal colectomy was considered necessary for the other patient. The duration of surgery was (260±100) minutes and the median estimated blood loss was 50 (20-200) mL. The median number of No. 253 lymph nodes harvested was 3 (0-20), and one patient (4.2%) had No.253 nodal metastases. The median postoperative hospital stay was 8 (4-23) days, and the incidence of complications 16.7% (4/24). There were no instances of postoperative colon ischemia or necrosis observed. One patient (4.2%) with stage IIA rectal cancer developed Grade B (Clavien-Dindo III) anastomotic leak and underwent elective ileostomy. The other complications were Grade I-II. Conclusions: PDM is frequently associated with mesenteric adhesions. Our proposed classification can assist surgeons in identifying the descending colon and mesocolon during adhesion lysis in laparoscopic surgery. It is crucial to protect the colorectal blood supply at the resection margin to minimize the need for unplanned extended colectomy, the Hartmann procedure, or permanent stomas.

ABSTRACT

Statins are a kind of prescription drug that is widely used to treat hyperlipidemia, coronary artery disease, and other atherosclerotic diseases. A common side effect of statin use is a mild rise in liver aminotransferases, which occurs in less than 3% of patients. Statin-related liver injury is most commonly caused by atorvastatin and simvastatin, but severe liver injury is uncommon. Therefore, understanding and evaluating hepatotoxicity and weighing the benefits and risks is of great significance to better realize the protective effect of statins.

ABSTRACT

With the expansion of mpox virus infection from endemic to a global epidemic in 2022, the WHO declared that the mpox event constituted a Public Health Emergency of International Concern. Due to the high degree of gene sequence similarity among orthopox viruses and cross-reactive antibodies induced by orthoviruses, smallpox vaccination may affect the immune response induced by mpox virus infection. The analysis of the protective effects of smallpox vaccination against mpox virus infection will help define the focus of prevention and control. In this review, we clarify the protection of the smallpox vaccine against mpox virus infection by analyzing the correlation between smallpox vaccination, immune response status, and clinical data and providing evidence for the prevention, control, and strategies of mpox epidemics.

ABSTRACT

Lung cancer is the most common in incidence and mortality worldwide. With the development of next generation sequencing (NGS) detection technology, more and more patients with rare anaplastic lymphoma kinase (ALK) fusion mutations were detected. A case of advanced lung adenocarcinoma with rare COX7A2L-ALK (C2:A20) fusion detected by NGS was reported in Peking Union Medical College Hospital, and all cases with rare ALK fusion mutations were searched from medical datebase from January 1, 2014 to March 31, 2021, to investigate the treatment of rare ALK fusion mutations with ALK inhibitors. The best response of the patient was assessed as partial response (PR) with Ceritinib treatment. By literature review, 22 cases of rare ALK fusion were reported in 19 articles. Combined with this case, 23 cases were analyzed. The objective response rate (ORR) was 82.6% (19/23) and disease control rate (DCR) was 95.7% (22/23) for rare ALK fusions patients treated with ALK inhibitors. Lung adenocarcinoma patients with rare ALK fusion could benefit from ALK inhibitors.

ABSTRACT

Objective:To investigate the application of scenario simulation teaching rounds in the residency training of teachers.Methods:A total of 56 faculty members in the surgical system were divided into the traditional method group and the scenario simulation group. The traditional method group adopted the training including multimedia centralized training, live rounds demonstration and observation, discussion and summary, while the scenario simulation group adopted the training including multimedia centralized training, scenario simulation demonstration and observation followed by step-by-step discussion and demonstration, review and summary. After the training, the training satisfaction questionnaires of the participants were collected. The participants were evaluated for teaching rounds before and after the training. The data were analyzed using Graphpad prism 7.Results:There were no significant differences between the two groups in terms of professional title, teaching years and gender ( P > 0.05). The average scores of teaching rounds before and after training in the scenario simulation group were (80.17±0.99) and (87.38±0.52). The average scores of teaching rounds before and after training in the traditional method group were (78.27±0.82) and (83.24±0.53). The teaching ability had improved after the teacher training in both groups, while the scenario simulation group performed significantly better than the traditional method group ( P < 0.05). The questionnaire survey showed that the satisfaction and training effect of the scenario simulation group were much higher than those of the traditional method group, and the difference was statistically significant ( P < 0.05). Conclusion:The scenario simulation teaching rounds training significantly improves the competency of teaching rounds of residential training teachers, as well as the scenario simulation capabilities of demonstration teachers and volunteers, which makes it worthy of further promotion in order to have a better performance on standardized residency training.

ABSTRACT

AIM: To investigate the impact of meteorological factors in different environments in the eastern and western regions of China on the incidence of lipid-abnormal dry eye.METHODS: This is a multicenter retrospective study. From March 1, 2021 to February 28, 2022, all patients with dry eye were selected from the ophthalmology clinic of Nanjing Hospital of Chinese Medicine Affiliated to Nanjing University of Chinese Medicine and Friendship Hospital of Xinjiang Yili Kazakh Autonomous Prefecture. General data(gender, age, employment and education)and climate data for outdoor environments(temperature, humidity, air quality index and wind)on the day of the visit were collected. Patients who met the inclusion and exclusion criteria were selected. Single factor, multiple factors and nonlinear model analysis were applied to identify environmental factors of lipid-abnormal dry eye in both regions.RESULTS: There was no significant difference in the incidence of lipid-abnormal dry eye between Nanjing and Yili in different seasons. The incidence of lipid-abnormal dry eye in Yili was significantly higher in all seasons than in Nanjing(P&#x0026;#x003C;0.001). The results of univariate research showed that the factors affecting the incidence of lipid-abnormal dry eye were gender, employment, humidity, air quality, and wind. The results of multivariate Logistic regression analysis showed that humidity, temperature and air quality were statistically significant, and remained significant after adjusting for the three confounding factors of age, gender and employment situation. Nonlinear analysis showed that the probability of lipid-abnormal dry eye increased with the decrease of temperature when the temperature was below 10℃; within the range of 10℃~15℃, the probability of lipid-abnormal dry eye tended to stabilize. When the temperature exceeded 15℃, the probability of lipid-abnormal dry eye increased with the increase of temperature. Humidity was negatively correlated with the onset of lipid-abnormal dry eye. As humidity increased, the probability of lipid-abnormal dry eye decreased.CONCLUSIONS: The risk of lipid-abnormal dry eye in Yili is higher than that in Nanjing throughout the four seasons. Humidity, temperature, air quality and other environmental and meteorological factors can all affect the incidence of lipid-abnormal dry eye.

ABSTRACT

OBJECTIVES@#To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China.@*METHODS@#A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups.@*RESULTS@#Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05).@*CONCLUSIONS@#There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

ABSTRACT

OBJECTIVE@#To assess the practical and health economical values of non-invasive prenatal test (NIPT) in Changsha Municipal Public Welfare Program.@*METHODS@#A retrospective analysis was carried out on 149 165 women undergoing NIPT test from April 9, 2018 to December 31, 2019. For pregnant women with high risks, invasive prenatal diagnosis and follow-up of pregnancy outcome were conducted. The cost-benefit of NIPT for Down syndrome was analyzed.@*RESULTS@#NIPT was carried out for 149 165 pregnant women and succeeded in 148 749 cases (99.72%), for which outcome were available in 148 538 (99.86%). 90% of pregnant women from the region accepted the screening with NIPT. 415 (0.27%) were diagnosed as high risk. Among these, 381 (91.81%) accepted amniocentesis, which led to the diagnosis of 212 cases of trisomy 21 (PPV=85.14%), 41 cases with trisomy 18 (PPV=48.81%) and 10 cases with trisomy 13 (PPV=20.83%). The sensitivity and specificity of NIPT for trisomy 21, trisomy 18 and trisomy 13 were (97.70%, 99.98%), (97.62%, 9.97%) and (100%, 99.97%), respectively. In addition, 213 and 30 cases were diagnosed with sex chromosomal aneuploidies (PPV=46.2%) and other autosomal anomalies (PPV=16.57%), respectively. For Down syndrome screening, the cost and benefit of the project was 120.79 million yuan and 1,056.95 million yuan, respectively. The cost-benefit ratio was 1: 8.75, and safety index was 0.0035.@*CONCLUSION@#NIPT is a highly accurate screening test for trisomy 21, which was followed by trisomy 18 and sex chromosomal aneuploidies, while it was less accurate for other autosomal aneuploidies. The application of NIPT screening has a high health economical value.

ABSTRACT

This study aimed to explore the effects of Gynostemma pentaphyllum saponins(GPs) on non-alcoholic fatty liver disease(NAFLD) induced by high-fat diet in rats and reveal the underlying mechanism. The NAFLD model rats were prepared with high-fat diet. Forty male Sprague Dawley(SD) rats were randomly assigned into the control group, model group, and low-, moderate-, and high-dose GPs(50, 100, and 150 mg·kg~(-1), respectively) groups. After intragastric administration for 8 continuous weeks, we determined the body weight, liver weight, the levels of total cholesterol(TC), triglyceride(TG), low-density lipoprotein cholesterol(LDL-c), high-density lipoprotein cholesterol(HDL-c), alanine aminotransferase(ALT), and aspartate aminotransferase(AST) in serum, and the levels of TC, TG, malondialdehyde(MDA), superoxide dismutase(SOD), catalase(CAT), and interleukin 6(IL-6) in the liver. Furthermore, we observed the pathological changes of liver tissue by oil red O staining and hematoxylin-eosin(HE) staining, sequenced the 16 S rRNA of the intestinal flora in rat feces, and determined the content of short-chain fatty acids in rat feces. The results showed that GPs inhibited the excessive weight gain of high-fat diet-induced NAFLD in rats, reduced the liver weight, lowered the TC, TG, LDL-c, AST, and ALT levels in serum(P<0.05), and rose the HDL-c level in serum(P<0.01). GPs relieved the liver damage caused by high-fat diet, mainly manifested by the lowered levels of TC, TG, MDA, and IL-6 in the liver(P<0.01) and elevated levels of CAT and SOD in the liver. Furthermore, GPs reversed the intestinal flora disorder caused by high-fat diet, restored the diversity of intestinal flora, increased the relative abundance of Bacteroides, and reduced the relative abundance of Firmicutes and the ratio of Firmicutes to Bacteroides. Moreover, GPs promoted the proliferation of beneficial bacteria such as Akkermansia, Bacteroides, and Parabacteroides, and inhibited the growth of harmful bacteria such as Desulfovibrio, Escherichia-Shigella, and Helicobacter. GPs increased the content of short-chain fatty acids(acetic acid, propionic acid, and butyric acid)(P<0.01). These findings indicate that GPs can alleviate the high-fat diet-induced NAFLD in rats via regulating the intestinal flora and short-chain fatty acid metabolism.

ABSTRACT

The incidence and spread of emerging infectious diseases are highly uncertain. This paper summarizes the uncertainty and complexity of emerging infectious disease, and suggests that for the response to the varied emerging infectious diseases in the future, it is still necessary for human to take the strategy of constantly strengthening the prevention and control capability and improving various preparedness protocols. For the better response to emerging infectious diseases and protection of people's health and life, the following measures can be taken, paying more attention to the layout of the infectious disease surveillance network, establishing and maintaining the laboratory surveillance network of infectious diseases, establishing and improving a "wartime-peacetime" transition mechanism or system of medical treatment and response, developing and improving the prevention and control plan for emerging infectious diseases, strengthening the training and rehearsal of emerging infectious disease treatment and response, establishing and improving the system for the grading, classification and stockpile of medical supplies for public health emergency response and establishing and maintaining the system of early warning of emerging infectious diseases and technical platform regulations.

ABSTRACT

Objective:To investigate the clinical features and outcomes of giant fetal hepatic hemangioma (GFHH).Methods:In this retrospective study, patients with GFHH from Guangzhou Women and Children's Medical Centre who received conservative management or medical intervention with a minimum of one year's follow-up after birth from August 2012 until March 2020 were enrolled. Prenatal and postnatal data were collected to analyze the pathological (size, location, and lesion type) and clinical manifestations, treatment, and prognosis of GFHH using independent sample t-test or Chi-square (or Fisher's exact) test. Results:(1) A total of 22 subjects were enrolled, including one preterm infant (4.5%), with an average gestational age of (38.9±1.5) weeks at birth, ranging from 33 +4 to 40 +3 weeks. Among them, 17 were male (77.3%), and five were female (22.7%). The gestational age at the first diagnosis was (35.0±2.8) weeks, ranging from 30 to 40 +1 weeks. Fifteen babies (68.2%) were born vaginally and seven (31.8%) by cesarean section due to fetal distress. Focal type accounted for 21 of the 22 (95.5%) patients, and multifocal type in one patient (4.5%). All the patients received B-ultrasonography on an average of 2.5 times (2-4 times) prenatally, which showed that the diameter of hepatic hemangioma increased with gestational age and reached its maximum at birth [56 mm (42-99 mm)]. Nine fetuses (40.9%) were diagnosed with GFHH with prenatal ultrasonography, and 12 with MRI. Among them, six fetuses were diagnosed with both ultrasonography and MRI. The other cases showed space-occupying lesions. (2) Ten babies received conservative management (conservative group), and 12 received drug therapy (treatment group). There was no significant difference between the two groups in gestational age at diagnosis or birth, birth weight, the maximum diameter of the tumor before birth, and location and classification of the lesions (all P>0.05). The incidence of thrombocytopenia in the treatment group was significantly lower than that in the conservative group (7/12 vs 0/10, Fisher's exact test, P=0.014). No abnormality of heart function or pulmonary hypertension was found in the conservative group, while two patients were complicated with pulmonary hypertension in the treatment group. The outcomes between the two groups were similar ( P>0.05). (3) During a median followed-up of 3.3 years (1.2-7.0 years), all patients survived, and none of the children in the conservative group received drug therapy. One of the ten patients in the conservative group had a complete tumor involution at two years old without recurrence, and the other nine had the tumor regressed in size. Besides oral propranolol, three of 12 cases in the treatment group also had dexamethasone at the early stage, two had rapamycin, and two received invasive therapy due to progressive enlargement of lesions at the early stage, with the lesions completely involuted in two cases at 1.7 and 5.5 years of age and regressed in the other ten cases. Conclusions:The diameter of GFHH increases with gestational age. Conservative management conservative is recommended for asymptomatic GFHH cases. For those affected with dyspnea and abdominal distention resulting in repeated vomiting, drugs therapy can be considered regardless of the test results, and invasive therapy is an option when drugs are ineffective. Some fetuses may have unsignificant imaging manifestations. Most children prenatally detected with giant hepatic hemangiomas can survive, and the tumor begins to regress after birth with a good long-term prognosis.

ABSTRACT

We report the clinical features of a case of congenital extralobar pulmonary sequestration in the left upper lobe supplied by the pulmonary artery. Prenatal ultrasound examination at 24 weeks of gestation revealed a high echogenic and uniform density mass in the fetal left thoracic cavity with the congenital pulmonary airway malformation volume vatio (CVR) of 1.16, which was supplied by pulmonary arterial vessels. MRI examination at 27 weeks indicated that the left lung volume increased to about 48.52 ml, while the right lung volume was about 8.56 ml giving the total lung volume of 57.08 ml. The congenital pulmonary airway malformation in the left upper lobe was suspected to be congenital bronchial atresia (CBA) or congenital lobar overinflation (CLO). The baby boy was born through vaginal delivery assisted by forceps at 38 +1 weeks without neonatal asphyxia. Postnatal CT and MRI were both indicated suspicious bronchial atresia in the left upper lobe. Bronchofibroscopy on postnatal day 2 excluded CBA or CLO and extralobar pulmonary sequestration was considered. Thoracoscopic surgery was performed due to continuous shortness of breath after birth, despite two-week conservative treatment including oxygenation, invasive and non-invasive mechanical ventilation,etc, and congenital extralobar sequestration was diagnosed. Blood supply from the left pulmonary artery was observed at the base of abnormal lung tissue. Resection of the pathogenic tissue of the left lung was performed thoracoscopically. The boy recovered and was discharged after the operation. Pulmonary sequestration was confirmed by histopathology.

ABSTRACT

Objective:To investigate the prediction value of observed to expected lung area to head circumference ratio (o/e LHR), measured at different gestational age with various methods, on indication for extracorporeal membrane oxygenation (ECMO) in fetuses with isolated left-sided congenital diaphragmatic hernia (CDH).Methods:Clinical data of 40 neonates who were diagnosed with left-sided CDH and treated in Guangzhou Women and Children's Medical Center were retrospectively collected from January 2017 to May 2021. The o/e LHRs were prenatally calculated using maximum diameter and tracing method at 22-24 and 31-33 weeks of gestation. According to whether the neonates had indications for ECMO after birth or not, they were divided into ECMO ( n=12) or non-ECMO group ( n=28). Differences in the o/e LHR and general situations between the two groups were analyzed using C hi-square test, independent sample t-test, and non-parametric Mann-Whitney U test. Binary logistic regression was used to analyze the influencing factors for ECMO requirement and receiver operating characteristic (ROC) curve was used to evaluate the value of o/e LHR in predicting the indication for ECMO. Results:Both maximum diameter and tracing method suggested that the o/e LHR at 31-33 gestational weeks was lower than that at 22-24 gestational weeks [maximun diameter method: 40.4 (32.9-51.5) vs 45.1 (36.3-53.4), Z=-2.48, P=0.013; tracing method: 38.6 (33.2-47.6) vs 44.1 (35.9-51.7), Z=-3.29, P=0.001]. There was no statistical difference in o/e LHR detected at the same gestational weeks between the two methods (both P>0.05). Binary logistic regression showed that o/e LHR measured at 31-33 gestational weeks using maximum diameter method was an independent protective factor for ECMO requirement ( OR=0.873, 95% CI: 0.790-0.965, P=0.008). ROC curve analysis showed that the area under the curve for evaluating the predictive value of o/e LHR for ECMO requirement was 0.830 with the sensitivity of 83.3% and the specificity of 71.4% when the cut-off value of o/e LHR at 31-33 gestational weeks was 38.195 measured by maximum diameter method. Conclusions:The o/e LHR measured at 31-33 weeks is lower than that at 22-24 weeks of gestation by both methods. The o/e LHR measured by maximum diameter method at 31-33 weeks of gestation may be useful for predicting the ECMO indication after birth but requiring comprehensive evaluation of clinical conditions due to its insufficient predicting power.

ABSTRACT

Objective:To compare the dosimetric difference between 3D-printed multi-channel applicator and conventional vaginal single-channel applicator for brachytherapy, aiming to provide guidance for patients receiving brachytherapy after cervical cancer surgery.Methods:From January 2019 to November 2020, 25 cervical cancer patients complicated with VAIN Ⅲ receiving 192Ir high-dose-rate brachytherapy after cervical cancer surgery were selected. Each patient was located by CT scanning with 3D-printed multi-channel applicator and conventional vaginal single-channel applicator, and corresponding plan and evaluation were carried out. The dose volume histogram (DVH) was obtained by inverse dose optimization algorithm. The dosimetric differences of high-risk clinical target volume (HRCTV), bladder and rectum during brachytherapy were compared with those of source applicators. The optimal treatment plan was selected. Results:D 90%, D 100%, V 100% and V 150% of the plans designed by 3D-printed individual multi-channel applicator had no significant differences compared with those designed by conventional single-channel applicator (all P>0.05). The bladder and rectal D 2cm 3 designed by 3D-printed multi-channel applicator were significantly lower than those using conventional single-channel applicator, and the differences were statistically significant (both P<0.05). Conclusion:The multi-channel individual applicator target made by 3D-printing technology has good conformal property, properly protects the bladder and rectum and possesses treatment advantages over conventional single-channel applicator.

ABSTRACT

Objective:To study the characteristics and related factors of neonatal intestinal necrosis caused by midgut volvulus.Methods:We retrospectively analyzed the clinical data of neonates with midgut volvulus who were admitted to Guangzhou Women and Children's Medical Center, from January 2009 to December 2019 and confirmed by surgery. The cases with intestinal necrosis belong to the intestinal necrosis group, and those without intestinal necrosis, the non-intestinal necrosis group which was randomly sampled at a ratio of about 4∶1 to the number of cases in the intestinal necrosis group. The two groups were compared in terms of personal history, age of onset, initial symptoms, vital signs within 2 h after admission, time from symptom onset to operation, clinical outcome, laboratory indicators within 2 h after admission, etc. Multivariate Logistic regression analysis was used to screen the related factors of intestinal necrosis in midgut volvulus. The effective warning indexes are screened by receiver operating characteristic (ROC) curve.Results:(1) Among 231 cases of midgut volvulus, 21 cases (9.1%, 21/231) had intestinal necrosis at the time of operation, 87 cases were included in the non-intestinal necrosis group. (2) The levels of heart rate within 2 h after admission, mean arterial pressure, WBC, C reactive protein (CRP), blood glucose and potassium in intestinal necrosis group were significantly higher than those in non-intestinal necrosis group ( P<0.05). Admission days of age, hemoglobin, serum albumin, serum sodium, pH and BE levels were significantly lower than those in the group without intestinal necrosis ( P<0.05). (3) In the multivariate analysis, increased heart rate, mean arterial pressure, serum CRP, and decreased serum sodium, serum albumin, and pH levels were predictors related to intestinal necrosis in patients with midgut volvulus. (4) The area under the ROC curve (AUC) of CRP was 0.883, the cutoff value was 9.88 mg/L, the sensitivity was 76.2%, and the specificity was 94.3%. The ROC curve of serum albumin was 0.792, the cut-off value was 36.65 g/L, the sensitivity was 70.1%, and the specificity was 94.3%. Conclusions:Heart rate, mean arterial pressure, increased CRP, decreased serum sodium, serum albumin and pH are helpful to predict whether intestinal necrosis occurs in midgut volvulus, and CRP > 9.88 mg/L and serum albumin < 36.65 g/L are likely warning indicators.

ABSTRACT

Objective:To study the clinical characteristics of double aortic arch (DAA) combined with aortoesophageal fistula (AEF), and summarize the diagnosis and treatment experience.Methods:Retrospective analysis was performed on the diagnosis and treatment of a newborn with hemorrhagic shock caused by DAA combined with AEF in the Guangzhou Women and Children's Medical Center. The key searching words included "double aortic arch", "aortoesophageal fistula", "vascular ring", "newborn or neonate", and "infant, newborn". The relevant reports were retrieved from databases of CNKI, Wanfang, VIP, PubMed, Springer Link, Google Scholar, Web of Science, Embase, Cochrane Library and OVID, to summarize the clinical features, diagnosis and treatment experience of neonates with DAA and AEF. The retrieval deadline was December 31, 2020.Results:A full-term female newborn was hospitalized for dyspnea immediately after birth, and failed to evacuate from the ventilator for several times. The patient was fed with nasogastric tube and transferred to our hospital because of hemorrhagic shock occurring in 32 days after birth, and gastrointestinal bleeding occurred repeatedly with the maximum bleeding volume reaching 200 ml/time. DAA was diagnosed by cardiac ultrasound and CT, AEF hemorrhage was finally confirmed by gastroscopy, aortography and operation. DAA correction and esophagus repair were successfully performed, and the infant recovered well after the operation. At 9-month old, the infant grew and developed well. At present, no reports of DAA combined with AEF neonates have yet to be published in medical literatures in China. Seven English language literatures included 7 cases of AEF complicated with DAA in neonatal period, 5 cases survived and 2 cases died have so far been reported. All patients have a long history of gastric tube indwelling.Conclusions:The incidence of DAA combined with AEF is rare in the newborn with respiratory and swallowing difficulties as the first manifestation. The disease symptoms progressed rapidly, and life-threatening digestive tract hemorrhage may occur, which often requires surgical treatment. Prolonged gastric tube retention should be avoided in DAA children to prevent the occurrence of AEF.
