When rescuing critically sick newborns，infusion remains one of the vital interventions.The main purpose of infusion is to maintain effective circulatory volume and to improve oxygen supply of tissues，whereas fluid overload（FO）might aggravate the patients' condition.Furthermore，due to the immature functions of various organs and the early physiological weight loss in newborns，FO is prevalent among critically sick newborns，and it is highly likely to be associated with organ dysfunction and adverse clinical outcomes.At present，the management of childhood FO is still controversial，and few researches were reported on neonatal FO.This article reviews the pathogenesis，management，evaluation and intervention of neonatal FO.

OBJECTIVE: Citri Reticulatae Pericarpium (Chenpi, CRP) is one of the most used traditional Chinese medicines with great medicinal, dietary and collection values, among which the Citrus reticulata cv. 'Chachi' (Citrus reticulata cv. Chachiensis) from Guangdong Xinhui is the geoherb of CRP. Xinhui CRP in the market was often counterfeited with other varieties or origins, molecular identification method can effectively distinguish different CRP varieties, but it's still a difficult problem to identify the same CRP variety from different origin. It is necessary to discover a new molecular marker to ensure the safe and effective application of Xinhui CRP. METHODS: We selected one of the most studied transcription factor families in Citrus genus, MYB, to design the specific candidate primers on the conserved region. The primers with good band repeatability and high polymorphism were screened for PCR amplification of the test materials, and the genetic similarity coefficient among different families, genera, species, and origins were calculated. The cluster analysis was performed by unweighted pair group method using arithmetic average (UPGMA). RESULTS: A total of ten MYB primers were screened out to identify Xinhui CRP from plants from different family (Panax ginseng and Morus alba), genus (Clausena lansium and Zanthoxylum schinifolium), and species (Citrus reticulata, C. sinensis and C. maxima). Furthermore, two from the ten primers, M1 and M10, were found to distinguish Xinhui CRP from other origins. There were 169, 113, 133 and 134 polymorphic bands in the identification of different families, genera, species, and origins respectively, and the accordingly polymorphism ration were 79.88%, 76.87%, 79.20% and 82.84%. Moreover, M1 was discovered to be the best primer to identify Xinhui CRP from other seven origins, the cluster analysis results based on the genetic similarity coefficients were consistent with the geographical distribution. CONCLUSION This study established a novel molecular identification method according to MYB transcription factor, which can analyze the potential parental relationship of CRP germplasm, as well as identify the quality and origins of Xinhui CPR.

Objective:To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

Neonatal hypoglycemia is one of the most common metabolic conditions in newborns.A considerable proportion of newborns are evaluated to be at risk of hypoglycemia，and transitional hypoglycemia is common in healthy newborns.A correlation between severe and prolonged hypoglycemia and neonatal hypoglycemic brain damage（HBD）in newborns has been proven.Factors such as hypoglycemia，glucose reperfusion，and blood glucose fluctuations are all involved in the damage process of HBD to a certain extent.This article reviews the relevant definitions of neonatal hypoglycemia，the characteristics of neonatal blood glucose metabolism，the related mechanisms of HBD，and possible treatment strategies to improve its prognosis.

Respiratory syncytial virus(RSV)infection is a potential susceptibility factor for recurrent wheezing,which can affect the occurrence and development of asthma through immune damage,airway epithelial barrier damage,airway inflammatory infiltration,airway hyperresponsiveness,and high expression of induced susceptibility genes.Traditional Chinese medicine believes that asthma caused by RSV infection is mostly caused by the imbalance of the body's qi after infection and the retention of evil qi.By combing the mechanism of RSV infection in the occurrence and development of asthma and the research on traditional Chinese medicine intervention in recent years,it is hoped to provide ideas for the future application of combined Chinese and Western medicine to prevent and treat asthma.

Formative assessment emphasizes timely feedback to guide and improve the learning process, benefiting both students and teachers through the evaluation–feedback–improvement–reevaluation mechanism. The Pediatric College of Chongqing Medical University has widely applied formative assessment to standardized residency training, and at the same time, has actively researched this method in undergraduate education to employ various formative assessment tools to establish a formative assessment-based pediatric education model that has specialized characteristics and can be popularized. We have demonstrated that the formative assessment-based education model can improve the teaching quality of pediatric medical education, and better meet the requirements of higher education and the new situation of medical education in the age of new medicine.

In view of the education and teaching problems in the course of Pediatrics about the construction of students' knowledge system and the cultivation of high-order abilities, on the basis of integrated organ and system courses, with the learner-centered and goal-oriented teaching concept seeking continuous improvement, we have developed a clinical problem-centered integrated teaching model in line with the learning law of medical students, innovatively integrating theoretical learning and clinical practice, and featuring the normalization of hybrid teaching and diversified teaching activities and evaluations. The curriculum innovation efforts substantially improve student satisfaction with teaching, and achieve good teaching effects. It has been actively promoted in the western pediatrics alliance of China, receiving extensive attention and positive feedback.
