		                        			The latest epidemiological data suggests that the situation of adult diabetes in China is severe, and metabolic diseases have become significant chronic illnesses that have a serious impact on public health and social development. After more than six years of practice, the National Metabolic Management Center(MMC) has developed distinctive approaches to manage metabolic patients and has achieved a series of positive outcomes, continuously advancing the standardized diagnosis and treatment model. In order to further improve the efficiency, based on the first edition, the second edition guideline was composed by incorporating experience of the past six years in conjunction with the latest international and domestic guidelines.

		                        			Objective: To analyze the incidence and related factors of drug resistance in HIV-infected pregnant and postpartum women in some areas of three western provinces of China from 2017 to 2019. Methods: From April 2017 to April 2019, face-to-face questionnaires and blood sample testing were conducted in all health care institutions providing maternal and perinatal care and midwifery-assisted services in 7 prevention of mother-to-child transmissi project areas in Xinjiang, Yunnan and Guangxi provinces/autonomous regions. Information was collected during the perinatal period and viral load, CD4+T lymphocytes and drug resistance genes were detected at the same time. The multivariate logistic regression model was used to analyze the relationship between different factors and drug resistance in HIV-infected pregnant and postpartum women. Results: A total of 655 HIV-infected pregnant and postpartum women were included in this study. The incidence of drug resistance was 3.4% (22/655), all of whom were cross-drug resistant. The rate of low, moderate and high drug resistance was 2.1% (14/655), 1.2% (8/655) and 0.8% (5/655), respectively. The drug resistance rate in the people who had previously used antiviral drugs was 1.9% (8/418), and the drug resistance rate in the people who had not used drugs was 5.9% (14/237). The NNRTI drug resistance accounted for 2.8% (18/655) and the NRTI drug resistance rate was 2.5% (16/655). The multivariate logistic regression model showed that the risk of HIV resistance was lower in pregnant women who had previously used antiviral drugs (OR=0.32, 95%CI: 0.11-0.76). Conclusion: Strengthening the management of antiviral drug use and focusing on pregnant and postpartum women who have not previously used antiviral drugs can help reduce the occurrence of drug-resistant mutations. Personalized antiviral therapy should be considered to achieve viral inhibition effects in clinical practice.

		                        			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.

		                        			OBJECTIVES:
		                        			To study the clinical efficacy of ultrasound-guided endoscopic retrograde appendicitis therapy in children with appendix-related chronic abdominal pain.
		                        		
		                        			METHODS:
		                        			A retrospective analysis was performed on the medical data of 30 children with the chief complaint of chronic abdominal pain who were admitted from August 2019 to May 2021. All the children were found to have inflammation of the appendix or intracavitary stool and fecalith by ultrasound and underwent ultrasound-guided endoscopic retrograde appendicitis therapy. The medical data for analysis included clinical manifestations, endoscopic findings, white blood cell count, neutrophil percentage, length of hospital stay, and cure rate.
		                        		
		                        			RESULTS:
		                        			Among the 30 children with chronic abdominal pain, there were 13 boys (43%) and 17 girls (57%), with a mean age of (9±3) years (range 3-15 years) at diagnosis. The median duration of the disease was 12 months, and the median length of hospital stay was 3 days. The children had a median white blood cell count of 6.7×109/L and a neutrophil percentage of 50%±13%. Fecalith and a large amount of feces were flushed out of the appendix cavity for 21 children (70%) during surgery. The follow-up rate was 97% (29/30), and the median follow-up time was 11 months (range 5-26 months). Of the 29 children, abdominal pain completely disappeared in 27 children (93%).
		                        		
		                        			CONCLUSIONS
		                        			Ultrasound-guided endoscopic retrograde appendicitis therapy is effective in children with chronic abdominal pain caused by feces or fecalith in the appendix cavity.

		                        			Methotrexate(MTX) is a commonly used antimetabolite, which can be used in the treatment of a variety of diseases. However, hepatotoxicity in the use of MTX severely limits its clinical use. Therefore, how to prevent and treat hepatotoxicity of MTX has become an urgent clinical problem. This paper summarizes and analyzes relevant literatures on the prevention and treatment of hepa-totoxicity caused by MTX with traditional Chinese medicines and natural medicines in recent years. MTX-induced hepatotoxicity mechanisms include folate pathway, oxidative stress damage and adenosine pathway, of which oxidative stress theory is the main research direction. A total of 14 kinds of traditional Chinese medicine and natural medicine extracts including white peony root, and 21 kinds of natural monomer compounds, including berberine, play an anti-MTX-induced hepatotoxic effect by resisting oxidative stress, inhibiting inflammation and regulating signal pathways. According to current studies on the prevention and treatment of hepatotoxicity induced by MTX with traditional Chinese medicines and natural medicines, there are insufficiencies, such as partial and superficial mechanism studies, inadequate combination of experimental research and clinical practice, non-standard experimental design and lack of application of advanced technologies and methods. This paper systematically reviewed the effects and mechanisms of traditional Chinese medicines and natural medicines against hepatotoxicity induced by MTX and defined current studies and deficiencies, in the expectation of proposing new study strategies and directions and providing scientific basis for rational clinical use of MTX and development of new drugs against MTX hepatotoxicity.

		                        			The aim of this paper was to investigate the effect and mechanism of anemoside B4 on renal ischemia reperfusion injury in rats. A total of 50 rats were randomly divided into the model group(NS) and anemoside B4 low-dose(1.25 mg·kg~(-1)), medium-dose(2.5 mg·kg~(-1)) and high-dose(5 mg·kg~(-1)) groups after the right kidney was removed and the left kidney was ligated to make the ischemia reperfusion model. Another 10 rats were selected as sham operation group only for normal control group(NS, received normal saline). Automatic biochemical analyzer was used to measure serum blood urea nitrogen(BUN), creatinine(Cre), cerebrospinal fluid(CSF) and urinemicroalbumin(mALB) levels after 5 days of tail vein injection treament. Total urine protein and total urinary albu-min were calculated and kidney samples were collected. Histopathological changes of renal tissues were observed by PAS staining. Western blot analysis was performed to detect the protein expressions of TLR4 and NF-κB in renal inflammatory factors related to NLRP3 pathway and TLR4/NF-κB pathway. The results showed that the levels of BUN, Cre, urinary total protein and urinary total albumin in the model group were significantly increased(P<0.01), with severe renal tubule injury was serious, manifested by obvious expansion of renal tubules, more serious tubular proteins, and some tubular epithelial cells were exfoliated. At the same time, the expression of inflammatory factors related to NLRP3 pathway and TLR4/NF-κB pathway increased significantly(P<0.01 or P<0.05). The levels of BUN, Cre were reduced in different doses of anemoside B4(P<0.05). The levels of total urinary protein and total urinary albumin were decreased in the low and high dose groups of anemoside B4.The level of total urinary albumin in the high-dose group of anemoside B4 was significantly reduced(P<0.05).Renal tubular injury was alleviated, tubular epithelial cell exfoliation was reduced, and the expression of related inflammatory factors was reduced in different degrees(P<0.01 or P<0.05). This study showed that anemoside B4 could alleviate renal ischemia-reperfusion injury in rats. And its mechanism may be related to the inhibition of inflammatory factors related to response mediated by NLRP3 pathway and TLR4/NF-κB pathway by anemoside B4.

		                        			In this study,in-depth systematic evaluation of rat of acute kidney injury(AKI) caused by renal arteriovenous ligation was conducted to better master and apply this model for drug research. Male SD rats of 2-3 months old were employed in this study.The left kidney was removed,and the right kidney received ligation for 40 min and reperfusion for 24 h. Serum creatinine(Crea),urea nitrogen(BUN) and the renal tissue sections were assayed as the basic indicators to evaluate their renal function. The mRNA expression of inflammatory necrosis factors and apoptotic factors was used to evaluate the mechanism of molecular pathophysiological changes. The results showed that the serum Crea and BUN caused by ligation of both renal arteries and veins were significantly higher than those of rats with renal artery ligation. After renal arteriovenous ligation for 40 min and reperfusion for 24 h in rats,the serum Crea of the rats varied from less than 100 μmol·L-1 to more than 430 μmol·L-1. Among them,5 rats showed less than 100 μmol·L-1 serum Crea,20 rats with 100-200 μmol·L-1 serum Crea and 12 rats with more than 430 μmol·L-1. Rats with serum Crea between 300-430 μmol·L-1 accounted for 66.3%(122/184) of the total number of the experiment rats. After 72 h reperfusion,serum Crea in the group of Crea 370-430 μmol·L-1 continued to increase,while the serum Crea in the group of Crea 200-300 μmol·L-1 and the group of Crea 300-370 μmol·L-1 recovered quickly. No matter serum Crea was elevated or decreased,the renal tubules showed pathological changes such as vacuolar degeneration or even necrosis. The mRNA expression levels of Toll-like receptor(TLR4),tumor necrosis factor(TNF-α) and interleukin(IL-6) in renal tissueswere significantly up-regulated,and the effect was most obvious in the group of serum Crea 370-430 μmol·L-1. The study indicated that the model for AKI caused by renal arteriovenous ligation and reperfusion is easy to operate,and the serum Crea and BUN have the characteristics of continuous increase,beneficial to the observation of drug effects. This acute kidney injury is mainly related to the pathophysiological response of inflammatory necrosis.

		                        			Objective: To investigate the current status and real performance of the detection of RUNX1-RUNX1T1 fusion transcript levels and WT1 transcript levels in China through interlaboratory comparison. Methods: Peking University People's Hospital (PKUPH) prepared the samples for comparison. That is, the fresh RUNX1-RUNX1T1 positive (+) bone morrow nucleated cells were serially diluted with RUNX1-RUNX1T1 negative (-) nucleated cells from different patients. Totally 23 sets with 14 different samples per set were prepared. TRIzol reagent was added in each tube and thoroughly mixed with cells for homogenization. Each laboratory simultaneously tested RUNX1-RUNX1T1 and WT1 transcript levels of one set of samples by real-time quantitative PCR method. All transcript levels were reported as the percentage of RUNX1-RUNX1T1 or WT1 transcript copies/ABL copies. Spearman correlation coefficient between the reported transcript levels of each participated laboratory and those of PKUPH was calculated. Results: ①RUNX1-RUNX1T1 comparison: 9 samples were (+) and 5 were (-) , the false negative and positive rates of the 20 participated laboratories were 0 (0/180) and 5% (5/100) , respectively. The reported transcript levels of all 9 positive samples were different among laboratories. The median reported transcript levels of 9 positive samples were from 0.060% to 176.7%, which covered 3.5-log. The ratios of each sample's highest to the lowest reported transcript levels were from 5.5 to 12.3 (one result which obviously deviated from other laboratories' results was not included) , 85% (17/20) of the laboratories had correlation coefficient ≥0.98. ②WT1 comparison: The median reported transcript levels of all 14 samples were from 0.17% to 67.6%, which covered 2.6-log. The ratios of each sample's highest to the lowest reported transcript levels were from 5.3-13.7, 62% (13/21) of the laboratories had correlation coefficient ≥0.98. ③ The relative relationship of the reported RUNX1-RUNX1T1 transcript levels between the participants and PKUPH was not always consistent with that of WT1 transcript levels. Both RUNX1-RUNX1T1 and WT1 transcript levels from 2 and 7 laboratories were individually lower than and higher than those of PKUPH, whereas for the rest 11 laboratories, one transcript level was higher than and the other was lower than that of PKUPH. Conclusion: The reported RUNX1-RUNX1T1 and WT1 transcript levels were different among laboratories for the same sample. Most of the participated laboratories reported highly consistent result with that of PKUPH. The relationship between laboratories of the different transcript levels may not be the same.
