Zuoguiwan， one of the classic formulas of traditional Chinese medicine （TCM）， has the effects of nourishing genuine Yin， supplementing essence， and replenishing marrow， and it is widely used in the clinical treatment of diseases caused by congenital essence deficiency. This article systematically reviewed the ancient books involving congenital deficiency and the modern research reports on the treatment of congenital deficiency with Zuoguiwan. From the formulation principle of Zuoguiwan and the TCM concept of congenital deficiency， this article discussed the theoretical basis of treating congenital deficiency with Zuoguiwan based on the modern research results. Ancient physicians have discovered that the deficiency of parents can lead to abnormal physical development and weakness of the offspring. ZHANG Jingyue divided congenital essence Qi into genuine Yin and primordial Yang and formulated Zuoguiwan based on the principle of Yin-Yang mutual assistance for supplementing congenital genuine Yin. Experimental studies have shown that Zuoguiwan can up-regulate the expression of connexin 43 （Cx43） protein and improve gap junction intercellular communication （GJIC） function to promote osteogenic differentiation and maturation of bone marrow mesenchymal stem cells and ameliorate abnormal bone development caused by congenital essence deficiency. Zuoguiwan can enhance the expression and activity of Reelin to ameliorate abnormal brain development. It can upregulate the expression of Cx43 protein to intervene in the phosphatidylinositol 3 kinase/protein kinase B （PI3K/Akt） pathway， thus repairing the reproductive functions. Zuiguiwan can promote the development and maturation of T cells and activate the Wnt/β-catenin signaling pathway in the thymus to improve immune functions. In addition， it can promote the expression of β-catenin and inhibit the expression of microtubule-associated proteins 1 light chain 3 （LC3） to attenuate skin dysfunctions. Moreover， Zuoguiwan can guide the differentiation of stem cells via the correlation between essence and vitality in TCM. Zuoguiwan has demonstrated significant therapeutic effects on some diseases in the pediatric， andrological， gynecological， geriatric， internal medicine， orthopedic and skin disease departments. On the basis of the results of experiments and clinical applications， this paper analyzes the specific connotation of congenital deficiency proposes that congenital deficiency should be subdivided into the four aspects of essence， Qi， Yin， and Yang. Congenital essence deficiency as the deficiency of genuine Yin can lead to deficiency of kidney essence in the offspring and dysfunction of kidney storing essence. Pharmacological studies have discovered that Cuscutae Semen， Lycii Fructus， and Achyranthis Bidentatae Radix in Zuoguiwan contain active components such as quercetin and kaempferol， which act on the targets such as recombinant prostaglandin endoperoxide synthase 2 （PTGS2）， interleukin-6 （IL-6）， mitogen-activated protein kinases （MAPK14）， tumor necrosis factor （TNF）， TP53， Vascular permeability factor A （VEGFA）， and albumin （ALB） to play a role in reproductive system development and hormone responses. Zuoguiwan has unique advantages over Liuwei Dihuangwan in nourishing congenital genuine Yin in the kidney and can achieve better therapeutic effects on the syndromes and diseases caused by congenital essence deficiency. This review is expected to enrich the knowledge about the efficacy and clinical application of Zuoguiwan， provide new perspectives and methods for the prevention and treatment of congenital deficiency and congenital essence deficiency， and give insights into the application of Zuoguiwan in modern healthcare， especially in the nurturing of offspring.

As a new class of acid inhibitors,potassium-competitive acid blocker(P-CAB)inhibits the conformational transition of H+,K+-ATPase with subsequent suppression of H+,K+exchanging by binding reversibly near the K+binding site of H+,K+-ATPase,which results in the inhibition of gastric acid secretion in a K+-competitive manner.The unique structure and novel mechanism of P-CAB contribute to the pharmaceutical characteristics superior to other PPIs,making it a new alternative for acid-related diseases(ARDs).Progress on pharmaceutical characteristics of P-CAB were reviewed in this paper.

Background::The Global Leadership Initiative on Malnutrition (GLIM) criteria were published to build a global consensus on nutritional diagnosis. Reduced muscle mass is a phenotypic criterion with strong evidence to support its inclusion in the GLIM consensus criteria. However, there is no consensus regarding how to accurately measure and define reduced muscle mass in clinical settings. This study aimed to investigate the optimal reference values of skeletal muscle mass index for diagnosing sarcopenia and GLIM-defined malnutrition, as well as the prevalence of GLIM-defined malnutrition in hospitalized cirrhotic patients.Methods::This retrospective study was conducted on 1002 adult patients with liver cirrhosis between January 1, 2018, and February 28, 2022, at Beijing You-An Hospital, Capital Medical University. Adult patients with a clinical diagnosis of liver cirrhosis and who underwent an abdominal computed tomography (CT) examination during hospitalization were included in the study. These patients were randomly divided into a modeling group (cohort 1, 667 patients) and a validation group (cohort 2, 335 patients). In cohort 1, optimal cut-off values of skeletal muscle index at the third lumbar skeletal muscle index (L3-SMI) were determined using receiver operating characteristic analyses against in-hospital mortality in different gender groups. Next, patients in cohort 2 were screened for nutritional risk using the Nutritional Risk Screening 2002 (NRS-2002), and malnutrition was diagnosed by GLIM criteria. Additionally, the reference values of reduced muscle mass in GLIM criteria were derived from the L3-SMI values from cohort 1. Multivariate logistic regression analysis was used to analyze the association between GLIM-defined malnutrition and clinical outcomes.Results::The optimal cut-off values of L3-SMI were 39.50 cm 2/m 2 for male patients and 33.06 cm 2/m 2 for female patients. Based on the cut-off values, 31.63% (68/215) of the male patients and 23.3% (28/120) of the female patients had CT-determined sarcopenia in cohort 2. The prevalence of GLIM-defined malnutrition in cirrhotic patients was 34.3% (115/335) and GLIM-defined malnutrition was an independent risk factor for in-hospital mortality in patients with liver cirrhosis ( Wald = 6.347, P = 0.012). Conclusions::This study provided reference values for skeletal muscle mass index and the prevalence of GLIM-defined malnutrition in hospitalized patients with liver cirrhosis. These reference values will contribute to applying the GLIM criteria in cirrhotic patients.

ObjectiveTo observe the effects of Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the Haizao Yuhutang （HYT） on oxidative stress in the liver of goiter rats under the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020. MethodA total of 128 male Wistar rats were randomly divided into a blank group， a model group， a euthyrox group （20 μg·kg^-1）， a HYT group （12.06 g·kg^-1）， a HYT without Sargassum （HYT-H） group （9.90 g·kg^-1）， a HYT without Glycyrrhizae Radix et Rhizoma （HYT-G） group （10.26 g·kg^-1）， a HYT without Sargassum and Glycyrrhizae Radix et Rhizoma （HYT-HG） group （8.10 g·kg^-1）， and a Sargassum and Glycyrrhizae Radix et Rhizoma （HG） group （3.96 g·kg^-1）. The blank group was given deionized water by gavage， and the others were given propylthiouracil （PTU） to replicate the goiter pathological model. Euthyrox was taken as a positive control drug， and the rest of the Chinese medicine groups were given the corresponding decoction by gavage， the material was collected 12 hours after the last dose. The serum levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， and the contents of superoxide dismutase （SOD）， glutathione peroxidase （GSH-Px）， malondialdehyde （MDA）， reactive oxygen species （ROS） in liver tissue were detected in each group. The pathological changes in the liver were observed via hematoxylin-eosin （HE） staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was utilized to detect the mRNA expressions of Kelch-like Ech-associated protein 1 （Keap1）， nuclear factor E₂-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， p53 and Caspase-3 in liver tissues. Western blot was adopted to detect the protein expressions of Nrf2 and HO-1 in liver tissues in oxidative stress-related signaling pathways. ResultCompared with control group， the model group showed significantly increased serum ALT level and contents of MDA and ROS in liver tissues （P<0.05， P<0.01）， significantly reduced activities of SOD and GSH-Px in the liver （P<0.01）， significantly increased mRNA expression of Keap1 （P<0.01）， and significantly decreased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. Compared with the model group， the HYT group manifested significantly reduced serum levels of AST， ALT， and ALP （P<0.05， P<0.01）， significantly reduced contents of MDA and ROS in liver tissue （P<0.01）， significantly increased the activities of SOD and GSH-Px （P<0.01）， significantly decreased mRNA expressions of Keap1， p53， and Caspase-3 （P<0.01）， and significantly increased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. ConclusionUnder the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020， Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the HYT on oxidative stress in the liver of goiter rats had different effects. The HYT that contains Sargassum and Glycyrrhizae Radix et Rhizoma has a protective effect on the liver of goiter rats， and the effect is better than that of the HG group， the euthyrox group， and the incomplete groups. Its mechanism may be related to activating the Nrf2/HO-1 signaling pathway to alleviate liver oxidative stress and inhibiting the p53/Caspase-3 signaling pathway to reduce hepatocyte apoptosis.

Objective To investigate dynamic shifts in the oral microbiota and their association with the progression and aggravation of radiotherapy-induced oral mucositis(RIOM)in patients with head and neck malignancies undergoing radiotherapy.Methods Based on 16S rRNA gene sequencing,dynamic changes of oral microbiota in patients was analyzed.Results Firmicutes,Bacteroidetes,and Actinobacteria consistently constituted the predominant bacteria in the oral cavity.While there were no significant changes in the abso-lute abundance of microbiota,there were notable alterations in their relative richness and evenness.Analyses including CCA/RDA and Kruskal-Wallis indicated a significant increase in the proportions of Streptococcus and Lactobacillus genera in the later stages post-radio-therapy,showing statistically meaningful differences.Conclusion RIOM is associated with dysbiosis of oral microbiota.Microbial dys-biosis may aggravate the severity of RIOM.Streptococcus and Lactobacillus could be closely related to the progression of RIOM,pending further validation through animal experiments.

Nanomaterial matrices have unique advantages in small molecule analysis by matrix-assisted laser desorption ionization mass spectrometry(MALDI-MS).On the basis of comparing different surfactants,a method for pre-coating nanocarbon sodium dodecyl sulfate(SDS)composite matrix was established,which could alleviate the issue of aggregation of nanocarbon particles as a matrix.The experimental results showed that the nanocarbon-SDS composite pre-coated matrix effectively suppressed the background ion peak of the nano matrix,significantly improved the MS peak intensity and signal-to-noise ratio of the tested substance.Under the optimal conditions,cholesterol,1,2-dipalmitoyl-sn-glyceryl-3-phosphorylcholine(DPPC),and triglyceride standards were analyzed,with intra-point repeatability(RSD)of MS peak intensity≤5%and inter-point repeatability≤7%.As to measurement of cyclic adenosine monophosphate and DPPC samples in the range of 0.05?1.0 mg/mL,linear correlation coefficient(R2)between peak intensity and concentration was greater than 0.993,indicating good quantitative analysis potential.The nanocarbon-SDS composite pre-coating matrix was used for MALDI-MS imaging of pig brain tissue,and the differences in component distribution between pig brain white matter and gray matter were observed,demonstrating the potential of nanocarbon-SDS composite pre-coating matrix for MALDI-MS imaging.

Objective To investigate the effect of varying ureteral wall thickness(UWT)at the site of ureteral stones on the clinical efficacy of ureteroscopic lithotripsy(URL).Methods The clinical data of 164 patients with ureteral stones in our hospital were retrospectively analyzed.According to different UWT,the patients were divided into the mild thickening group(84 cases,UWT<3.16 mm),the moderate thickening group(31 cases,UWT 3.16 to 3.49 mm),and the severe thickening group(49 cases,UWT>3.49 mm),and the differences of clinical related indicators among the three groups were compared.Results The incidence of postoperative renal colic and leukocyte disorder in the mild thickening group and the moderate thickening group were lower than those in the severe thickening group,and the differences were statistically significant(P<0.05).The postoperative catheterization time in the mild thickening group and the moderate thickening group were shorter than that in the severe thickening group,and the incidences of secondary lithotripsy,residual stones and stone return to kidney in the mild thickening group and the moderate thickening group were lower than those in the severe thickening group,with statistically significant differences(P<0.05).The length of hospital stay and hospitalization cost in the mild thickening group and the moderate thickening group were shorter/less than those in the severe thickening group,with statistically significant differences(P<0.05).Conclusion With the increase of UWT(especially when UWT>3.49 mm),the incidence of postoperative complications and hospitalization cost of URL increase to varying degrees,and the surgical efficacy decreases.In clinical work,UWT measurement holds potential value in predicting the surgical efficacy and complications of URL.
