The incidence of decreased ovarian reserve(DOR)is gradually increasing,with fluctuations in hormone levels causing a series of clinical syndromes.Among these,sleep disorders stand out as prominent symptoms,clinically manifested by difficulties in falling asleep,shortened sleep duration,and poor sleep quality,severely impacting the physical and mental health as well as the quality of life of women.Clinical observations have found a close relationship between decreased ovarian reserve and sleep disorders,where the two interact causally and reciprocally.Western medicine primarily focuses on improving behavioral cognition,administering sedatives and hypnotics,and hormone replacement therapy,albeit with certain limitations in efficacy.Traditional Chinese medicine emphasizes holistic views and syndrome differentiation in treatment,offering low side effects and unique advantages.This review summarizes recent literature on the research progress of sleep disorders and DOR from both Western and traditional Chinese medicine perspectives,providing reference for clinical treatment.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

OBJECTIVE: To observe the effect of acupuncture at "Feishu" (BL 13) + "Dingchuan" (EX-B 1) and "Kongzui" (LU 6) + "Yuji" (LU 10) for the airway remodeling in asthma rats based on the transforming growth factor-β1 (TGF-β1)/ Smad family member 3 (Smad3) signaling pathway; and explore the efficacy difference between the two acupoint combinations. METHODS: Forty SPF male SD rats, aged 4 weeks, were randomly divided into a blank group (n = 10) and a modeling group (n = 30). The ovalbumin (OVA) sensitization method was used to establish asthma model in the modeling group. After successful model preparation, the rats of the modeling group were randomized into a model group, an acupuncture at "Feishu" (BL 13) + "Dingchuan" (EX-B 1) (AAF) group, and acupuncture at "Kongzui" (LU 6)+"Yuji" (LU 10) (AAK) group, with 10 rats in each one. Starting from day 15 of the experiment, 5 min after motivating, acupuncture was applied to "Feishu" (BL 13) + "Dingchuan" (EX-B 1) and "Kongzui" (LU 6)+"Yuji" (LU 10) in the AAF group and the AAK group respectively. The intervention was delivered for 30 min each time, once daily, lasting 3 weeks consecutively. Using lung function detector, the airway resistance (RL) and dynamic compliance (Cdyn) of the lungs were detected. The histomorphology of lung tissues was detected with HE staining and Masson staining, and the mRNA and protein expression of TGF-β1 and Smad3 in lung tissues was detected with the real-time PCR and Western blot methods. RESULTS: Compared with the blank group, RL was increased and Cdyn was decreased in the rats of the model group (P<0.01); and RL was reduced and Cdyn was increased in the AAF group and the AAK group when compared with those in the model group (P<0.01, P<0.05). The rats of the model group had bronchial lumen stenosis, inflammatory cell infiltration, collagen fibre hyperplasia and thickened smooth muscle in the lung tissues when compared with those in the blank group; and in comparison with the model group, all of the above morphological changes were attenuated in the AAF group and the AAK group. Besides, these morphological changes of the lung tissues were more alleviated in the AAF group when compared with those in the AAK group. In comparison with the blank group, the mRNA and protein expression of TGF-β1 and Smad3 of the lung tissues was increased in the model group (P<0.01), and it was reduced in the AAF group and the AAK group when compared with that in the model group (P<0.05, P<0.01). The mRNA expression of TGF-β1 and Smad3 was lower in the AAF group when compared with that in the AAK group (P<0.05). CONCLUSION Acupuncture at either "Feishu" (BL 13)+"Dingchuan" (EX-B 1) or "Kongzui" (LU 6)+"Yuji" (LU 10) reduces the airway remodeling in the rats with asthma, which may be related to the down-regulation of mRNA and protein expression of TGF-β1 and Smad3. The better efficacy is obtained with acupuncture at "Feishu" (BL 13)+"Dingchuan" (EX-B 1).

There were no significant differences in the concentrations of total alpha, total beta, 90Sr, 137Cs, 226Ra, U and Th in different water sources and different years ( P>0.05). There were no significant differences in the concentrations of total alpha, total beta, 90Sr, 137Cs and 226Ra during different water periods ( P>0.05). There were statistical differences in U activity concentration in different water periods ( H=16.53, P<0.05), and statistical differences in Th activity concentration in different water periods ( H=15.61, P<0.05). Conclusions:The survey showed that the total alpha, total beta, 90Sr, 137Cs, 226Ra, U and Th radioactivity levels in drinking water sources in Chengdu, Yibin, Mianyang, Guangyuan and Leshan of Sichuan province were at the same level as the relevant data in the Natural environmental radioactivity level in China published by the State Environmental Protection Bureau in 1995. All of there values were within the data range released by the 2013-2021 National Radiation Environment Monitoring Quality Report issued by the Radiation Environment Monitoring Technology Center of the Ministry of Ecology and Environment. The radioactivity level in water sources in the five key cities was at a safe level.

Surgical operation is the main treatment method for pancreatic cancer, and in clinical practice, radical surgery for pancreatic cancer is often combined with superior mesenteric-portal vein confluence pancreaticoduodenectomy to achieve R0 resection. However, severe left-sided portal hypertension (LSPH) may occur after splenic vein dissection, resulting in a series of pathological changes such as congestive splenomegaly, thrombocytopenia, backflow obstruction of splenic vein, and gastrointestinal varices, and in some cases, it can lead to fatal gastrointestinal hemorrhage and hemorrhagic shock. Therefore, in order to better manage LSPH in clinical practice, this article systematically analyzes and reviews the pathogenesis, treatment regimens, and control strategies of LSPH after combined superior mesenteric-portal vein confluence pancreaticoduodenectomy and put forward corresponding suggestions based on current studies.

Objective: To investigate the genetic and genomic profiling of juvenile myelomonocytic leukemia (JMML) and factors affecting its survival rate. Methods: Clinical characteristics, cytogenetics, molecular biology results and survival status of children with 27 JMML cases admitted to the Hematology Department of Children's Hospital, Capital Institute of Pediatrics from December 2012 to December 2021 were analyzed retrospectively, and the outcomes of the children were followed up. Kaplan-Meier method was used for survival analysis. Univariate analysis was used for analyzing factors affecting the overall survival (OS) rates of patients who received hematopoietic stem cell transplantation (HSCT). Log-Rank test was used for comparison of survival curves. Results: Among 27 JMML cases, there were 11 males and 16 females. The age of disease onset was 28 (11,52) months. There are 20 cases of normal karyotype, 4 cases of monosomy 7, 1 case of trisomy 8,1 case of 11q23 rearrangement and 1 case of complex karyotype. A total of 39 somatic mutations were detected.Those involved in RAS signal pathway were the highest (64%(25/39)), among which PTPN11 mutation was the most frequent (44% (11/25)). A total of 17 cases (63%) received HSCT, 8 cases (30%) did not receive HSCT, and 2 cases (7%) lost follow-up. For children receiving transplantation, the follow-up time after transplantation was 47 (11,57) months. The 1-year OS rate of high-risk transplantation group (17 cases) and high-risk non transplantation group (6 cases) was (88±8)% and (50±20)% respectively, with a statistically significant difference (χ²=5.01, P=0.025). The 5-year OS rate of the high-risk transplantation group was (75±11)%. The survival time of those who relapsed or progressed to acute myeloid leukemia after transplantation was significantly shorter than that of those who did not relapse (χ²=6.80, P=0.009). The OS rate of patients with or without PTPN11 mutation was (81±12) % and (67±19)% respectively (χ²=0.85, P=0.356). Conclusions: The main pathogenesis involved in JMML is gene mutation related to RAS signaling pathway, and the most common driver gene of mutation is PTPN11. Allogeneic HSCT can significantly improve the survival rate of high-risk JMML patients. The recurrence or progression after transplantation was related to poor prognosis.

ACC oxidase (ACO) is one of the key enzymes that catalyze the synthesis of ethylene. Ethylene is involved in salt stress response in plants, and salt stress seriously affects the yield of peanut. In this study, AhACO genes were cloned and their functions were investigated with the aim to explore the biological function of AhACOs in salt stress response, and to provide genetic resources for the breeding of salt-tolerant varieties of peanut. AhACO1 and AhACO2 were amplified from the cDNA of salt-tolerant peanut mutant M29, respectively, and cloned into the plant expression vector pCAMBIA super1300. The recombinant plasmid was transformed into Huayu22 by pollen tube injection mediated by Agrobacterium tumefaciens. After harvest, the small slice cotyledon was separated from the kernel, and the positive seeds were screened by PCR. The expression of AhACO genes was analyzed by qRT-PCR, and the ethylene release was detected by capillary column gas chromatography. Transgenic seeds were sowed and then irrigated with NaCl solution, and the phenotypic changes of 21-day-seedings were recorded. The results showed that the growth of transgenic plants were better than that of the control group Huayu 22 upon salt stress, and the relative content of chlorophyll SPAD value and net photosynthetic rate (Pn) of transgenic peanuts were higher than those of the control group. In addition, the ethylene production of AhACO1 and AhACO2 transgenic plants were 2.79 and 1.87 times higher than that of control peanut, respectively. These results showed that AhACO1 and AhACO2 could significantly improve the salt stress tolerance of transgenic peanut.

(5) The cure rate of premature infants with RDS was 70.8% (247/349) in 2021, which was significantly higher than that in 2016 [56.2% (181/322), χ2=15.37, P<0.001]. Moreover, the rate of withdrawing treatment and the total mortality rate was lower in 2021 than in 2016 [7.7% (27/349) vs 14.3% (46/322), χ2=7.41; in-hospital: 1.4% (5/349) vs 5.6% (18/322), χ2=8.74; out of hospital: 8.3% (29/349) vs 13.7% (44/322), χ2=4.96; all P<0.05]. Conclusions:The clinical management of RDS in premature infants in the involved hospitals has been improved. However, there is room for improvement in prenatal examinations.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

OBJECTIVE: To study the clinical effect of continuous subcutaneous insulin infusion (CSⅡ) versus multiple daily injection (MDI) on blood glucose control in children with type 1 diabetes mellitus (T1DM). METHODS: A retrospective analysis was performed on the medical data of 91 children with T1DM who were treated with CSⅡ for more than 1 year and 75 children with T1DM who were treated with MDI. The two groups were compared in terms of glycosylated hemoglobin (HbA1C) and the recurrence of diabetic ketoacidosis (DKA) to evaluate the difference in the efficacy during the 3-year follow-up. A survey was conducted for the children in the CSⅡ group and their family members to investigate the degree of satisfaction with insulin pump. RESULTS: There was no significant difference in age, sex, and course of diabetes between the CSⅡ and MDI groups at disease onset and in the first year, the second year, and the third year of follow-up ( CONCLUSIONS Children with T1DM treated with CSⅡ have a better control of blood glucose than those treated with MDI, and children and their family members are satisfied with CSⅡ treatment. Therefore, it holds promise for clinical application.
