ObjectiveTo investigate the therapeutic effect of Qinggongtang in regulating Glu/GABA metabolic balance and the mechanism of its anxiolytic effect on rat models of anxiety. MethodFifty-four rats were randomly divided into normal, model, diazepam (0.225 mg·kg-1), and low-dose, medium-dose, and high-dose groups of Qinggongtang (5.085, 10.17, 20.34 g·kg-1), with nine rats in each group. Except for the normal group, the other groups were subjected to indeterminate vacutainer stress and chronic restraint stress for 12 days to prepare the anxiety model. On the 3rd day of the stress, 10 days of corresponding drug intervention was started. At the end of the drug treatment, the anxiety level of rats in each group was evaluated by the elevated cross maze experiment (EPM) and the light and dark box experiment (LDB), and the effect of Qinggongtang on the anxiety behavior of rats was preliminarily analyzed. The levels of Glu and GABA in the amygdala tissue of the rats were detected by enzyme linked immunosorbent assay (ELISA), and the changes in the synaptic ultrastructure of the amygdala of the rats in each group were observed by electron microscopy. The mRNA expression of glutamic acid decarboxylase (GAD65 and GAD67), glutamine synthetase (GS), and glutamate transporter-1 (GLT-1) in the amygdala were detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), and their protein expression was detected by Western blot. ResultCompared with those in the normal group, rats in the model group showed an obvious anxiety state and dull yellow and lusterless fur. They were irritable, easy to anger, and preferred to curl up in the corner. The number of times the EPM entered the open arm and the residence time in the open arm were significantly reduced (P<0.01), and the residence time in the open box and the number of times the LDB went through the box were significantly reduced (P<0.01). The content of Glu in the amygdala was increased (P<0.01), and the content of GABA was reduced (P<0.01). The value of Glu/GAB was elevated (P<0.01), and the number of synaptic and pre-synaptic membrane vesicles in the amygdala was decreased. Sparse dense material in the post-synaptic membrane, increased synaptic gap, slightly disrupted internal structure, and decreased mRNA and protein expressions of GAD65, GAD67, GS, and GLT-1 in the amygdala were observed (P<0.01). Compared with those in the model group, rats in the medium-dose and high-dose groups of Qinggongtang and the diazepam group had bright fur, sensitive reactions, and more active behavior. The number of times EPM entered the open arm and the residence time in the open arm increased significantly (P<0.01), and the residence time in the open box and the number of times the LDB went through the box increased significantly (P<0.01). The content of Glu in all-dose groups of Qinggongtang and the diazepam group decreased (P<0.05, P<0.01), while GABA content increased (P<0.05, P<0.01). The value of Glu/GABA decreased (P<0.01), and the internal and external synaptic structure of each groups of Qinggongtang and the diazepam group was more complete. Synapses and vesicles were numerous, and the synaptic gap was more clearly defined. The efficacy of the high-dose group of Qinggongtang and the diazepam group was the best, and the mRNA and protein expressions of GAD65, GAD67, GS, and GLT-1 in the amygdala were increased in the high-dose group of Qinggongtang and diazepam group (P<0.05, P<0.01). ConclusionQinggongtang can improve synaptic plasticity and affect the expression of GAD65, GAD67, GS, and GLT-1 in the amygdala of rats to regulate Glu/GABA metabolic balance and thus exert anxiolytic effects.

Objective:To study the short-term clinical outcomes of different courses of antenatal corticosteroids (ACS) for preterm twins.Methods:From January 2017 to December 2021, preterm twins with gestational age (GA) 24-34 weeks admitted to the neonatal ward of our hospital and received ACS were retrospectively studied. The infants were assigned into single-course group, partial-course group and multiple-course group according to ACS courses. The short-term clinical outcomes were compared among the groups. SPSS software version 25.0 was used for statistical analysis.Results:A total of 286 infants were enrolled in this study, including 128 in single-course group, 89 in partial-course group and 69 in multiple-course group. Compared with single-course group, the risks of neonatal respiratory distress syndrome (RDS) in both partial-course group ( OR=2.332, 95% CI 1.028-5.293, P=0.043) and multiple-course group ( OR=3.872, 95% CI 1.104-13.584, P=0.034) were higher. The birth length in multiple-course group ( β=-0.016, 95% CI -0.029 - -0.002, P=0.024) was lower than single-course group. Conclusions:The risks of neonatal RDS in preterm twins are higher in partial-course and multiple-course of ACS. A full course of ACS should be used to prevent neonatal RDS until further evidence of effectiveness is available.

The use of bariatric and metabolic surgery as a central treatment for obesity has been steadily increasing. BMI, as a widely used metric for assessing obesity, has considerable relevance in the field of metabolic research. However, its limitations, such as its inability to account for variations in fat distribution, remain a subject of considerable controversy. In recent years, there has been a surge of interest in the relationship between changes in body composition and the risk of metabolic disease. Consequently, the study of the effects of bariatric and metabolic surgery on changes in body composition has become a major focus of bariatric and metabolic surgery research. As a potential replacement for BMI, body composition measurements are expected to improve and standardize the assessment of the effectiveness of bariatric and metabolic surgery. This underscores the urgent need for the development of methods and standards for body composition measurement. This paper undertakes a comprehensive review of the existing evidence on the application of body composition measurement techniques for the efficacy evaluation of bariatric and metabolic surgery. The intent is to provide new insights and pave the way for the exploration of future research directions in this area.

ObjectiveTo observe the intervention effect of Ruyi Zhenbao pills (RYZBP) on central pain after thalamic stroke in mice and explore the underlying mechanism. MethodThe central post-stroke pain syndrome (CPSP) model was induced by stereotactic injection of type Ⅳ collagenase into the hypothalamus in mice. The mice were divided into a sham group, a model group, low-, medium-, and high-dose RYZBP groups (0.65, 1.3, 2.6 g·kg-1), and a pregabalin group (0.075 g·kg-1). Seven days after modeling, the mice in the groups with drug intervention were administered with corresponding drugs by gavage according to the body mass, once per day for 25 days, while those in the sham group and the model group received an equal volume of normal saline. During this period, mechanical pain and cold pain were detected at different time points, and the apoptotic state of brain tissue cells was detected by in situ terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL). The 36 classical broad-spectrum inflammatory factors were quantitatively analyzed by liquid-phase chip technology, and differential molecules were screened out and verified by Western blot and enzyme-linked immunosorbent assay (ELISA). ResultCompared with sham operation group, mechanical pain threshold and cold sensitive pain threshold in model group were significantly changed (P<0.01). TUNEL results showed that apoptosis of brain cells was obvious. Western blot and ELISA results showed that the expressions of interleukin-1α (IL-1α) and chemokine ligand 5 (CCL5) increased in hypothalamus tissue and serum, while the expressions of Ang-2, granulocyte-colony-stimulating factor (G-CSF) and IL-4 decreased significantly (P<0.01). Compared with model group, RYZBW dose groups significantly increased mechanical pain threshold, decreased cold sensitivity pain threshold, decreased hypothalamus cell apoptosis ratio (P<0.01), decreased the expression of IL-1α and CCL5 in hypothalamus tissue and serum, while the expression of ANG-2, G-CSF and IL-4 were significantly increased (P<0.05). ConclusionRYZBP can relieve hyperalgesia in CPSP mice, and its mechanism is related to the regulation of the expression of pro-/anti-inflammatory factors IL-1α, CCL5, IL-4, G-CSF, and Ang-2.

BACKGROUND:
Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE).
METHODS:
This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE.
RESULTS:
This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively.
CONCLUSIONS
Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

OBJECTIVE:
To evaluate the outcome of re-pregnancy in women with uterine artery embolization(UAE)for postpartum hemorrhage(PPH).
METHODS:
Clinical data of 117 pregnant women with previous PPH admitted in Ningbo Women and Children's Hospital from January 2010 to January 2016 were retrospectively analyzed. Among them 40 cases were treated with UAE (UAE group) and 77 cases were not treated with UAE (control group). The outcomes of re-pregnancy were followed up and compared between two groups.
RESULTS:
There were significant differences in the incidence of induced abortion in early pregnancy and cesarean scars pregnancy (CSP) between the two groups (<0.05 or <0.01). In the UAE group, the incidence of PPH, placental accretion and hysterectomy rate was significantly higher than that of control group (<0.05 or <0.01). Multivariate analysis showed that UAE was independent risk factor for CSP, placenta accretion, PPH and hystere-ctomy (<0.05 or <0.01).
CONCLUSIONS
The overall fertility and re-pregnant outcomes in women with previous UAE for PPH are favorable. However, the risk of CSP, placenta accretion and associated recurrence of PPH and hysterectomy is higher in women receiving UAE during subsequent pregnancy.

OBJECTIVE: To provide reference for perfecting the quality standard revision of TCM preparations in medical institutions, and improving the quality standard of TCM preparations in medical institutions. METHODS: By sorting out the quality standards of TCM preparations in Guangdong provincial medical institution preparation specification, this paper summarized the main problems and put forward suggestions for improvement. RESULTS & CONCLUSIONS: There are 897 kinds of TCM preparations included in the Guangdong provincial medical institution preparation specification. The recent quality standards (2017 edition) have been greatly improved compared with those of the first edition (1985 edition); however, there are still some problems in the overall quality control of preparations, quantitative control of indicative components, project specificity, source control of medicinal materials, control of medicinal materials not included in the Chinese Pharmacopoeia and quality standards of the same series of varieties. It is suggested that on the premise of considering both advancement and applicability, the quality control of the whole, local and toxic preparations of TCM hospitals should be strengthened, the detection methods with good specificity and reproducibility should be properly updated, the control of key parameters of production process should be strengthened, the quality standard of TCM preparations in medical institutions should be fully improved, so as to provide the products with safe, effective and controllable in quality products in medical institutions.
