To assess the efficacy and safety of aromatase inhibitors (AIs) combined growth hormone in treatment of adolescent boys with short stature.

One hundred and fifty-one short stature pubertal boys with age of 10-14 years and bone age of 13-15 years, who were admitted to the Department of Pediatrics, the First Affiliated Hospital, Zhejiang University School of Medicine, were included in this trial. According to their own or parents' intention, the children were divided into recombinant human growth hormone (rhGH)+AI group (
=108) and rhGH group (
=43). All children were injected subcutaneously with rhGH 0.15-0.2 IU·kg
·d
, and those in rhGH+AI group were additionally given 2.5 mg/d letrozole or 1 mg/d anastrozole, orally for 12 months or longer. The children were followed-up every 3 months. During the follow-up visit, the predicted adult height (PAH), sex hormone level, glucose and lipid metabolism, and other indicators were measured, and adverse reactions were monitored.

After intervention, there welay the growth of BA and effectively improve the PAH of adolescent boys with larger bone age. However, the occurrence of adverse reactions of AI should be closely monitored during treatment.
To investigate the relationship of group B
(GBS) colonization in late pregnancy with perinatal outcome.

Pregnant women who underwent antenatal check-up at General Hospital of PLA Eastern Theater Command and the First Affiliated Hospital of Nanjing Medical University from January 2016 to December 2018 were enrolled in the study. The vaginal and rectal swab samples were collected for GBS culture at 35-37 weeks of pregnancy. The perinatal outcomes of positive and negative GBS groups were compared. The GBS-positive group samples were tested for antibiotic susceptibility. In GBS positive group the maternal and child perinatal outcomes were compared between pregnant women with antibiotics treatment and those without antibiotics.

A total of 13 000 pregnant women were enrolled, and the overall colonization rate of GBS was 3.65%(475/13 000). The colonization rate of GBS in the vagina was 2.33%(303/13 000), and the colonization rate in the rectum was 1.75%(227/13 000). Through the collection and detection of rrate of GBS is low. The detection of GBS can be significantly improved by supplementing rectal examination. Ceftriaxone, ampicillin and penicillin are currently the drugs of choice for the prevention and treatment of GBS-related diseases. GBS infection can increase the incidence of maternal and child complications. The use of antibiotics during labor can improve the outcome of mothers and infants.

Critically ill COVID-19 patients are often in a state of high inflammation, high stress, high catabolism, and their energy consumption increases significantly. All critically ill patients with COVID-19 should be screened for nutritional risk with NRS-2002 or Nutric tool in the early stage. If there is a risk of malnutrition, subjective global assessment (SGA) or Global Leadership Initiative on Malnutrition (GLIM) are further used for malnutrition assessment. After assessment, the daily energy, protein, electrolyte and liquid quantity needed by the patients should be determined according to the actual condition. Then, according to the degree of gastrointestinal function impairment in patients, the oral nutrition supplement, enteral nutrition, parenteral nutrition or their combination are selected for nutritional support. For patients with normal gastrointestinal function who require prone position ventilation or receive extracorporeal membrane oxygenation (ECMO) treatment, enteral nutrition is recommended as the first choice. In addition, in the process of nutrition implementation, it is necessary to closely monitor the adverse reactions such as abdominal distention, diarrhea, regurgitation, phlebitis and liver function damage, timely adjust the nutrition program to ensure the smooth implementation of nutritional support. Based on the metabolic characteristics of critically ill patients with COVID-19, this paper makes a summary and suggestion on the following perspectives such as nutritional risk screening and assessment, target amount of nutritional treatment, nutritional intervention and treatment, nutritional support of special populations, and common adverse reactions in nutritional support treatment, so as to provide reference for individualized nutritional support therapy of critically ill patients with COVID-19.
To assess the efficacy of letrozole in treatment of children with congenital adrenal hyperplasia (CAH) due to steroid 21-hydroxylase deficiency (21-OHD).

Twenty eight children, including 19 boys and 9 girls aged 4-10y, with CAH due to 21-OHD were enrolled in the study. At the first six months of study, all children received conventional treatment with hydrocortisone or fludrocortisone, then letrozole was added to original regimen. The height velocity (HV), difference between bone age and chronological age (BA-CA), height standard diviation score based on bone age (HtSDS
), predicted adult height (PAH), Tanner phase, sex hormone, and possible adverse reaction were evaluated and compared between those before and after letrozole treatment.

After 6 months of letrozole treatment, there was significant deceleration of HV, but it would recover soon. click here There was significant increase of HtSDS
after 12 months of letrozole treatment (
< 0.05 or
< 0.01), and significant changes in BA-CA afterOHD, especially for those with high BA and low PAH.
To establish a clinical prediction model of the mid-term fatality risk after radical resection in patients with primary hepatocellular carcinoma (HCC) based on the albumin-bilirubin (ALBI) grade and to assess its prediction value.

Clinical data of 533 patients who received HCC radical resection in Jinhua Hospital of Zhejiang University, Jinhua People's Hospital, Jinhua Hospital of Traditional Chinese Medicine and Jinhua Guangfu Hospital from January 2010 to August 2016 were retrospectively reviewed. In the training group (
=407), Cox model was used to screen the clinical risk factors of postoperative death, and a predictive model based on ALBI grade was established and then examined in the validation group (
=126). The value of the prediction model was assessed by ROC curve and calibration curve; the prediction results of the model were visualized by the nomogram for the convenience of clinical use.

Cox model showed that ALT ≥ 80 U/L, tumor maximum diameter ≥ 5 cm, portal vein tumor thrombus and ALBI grade 2 were independent risk factors for the prognosis of patients with HCC radical resection.
