Kidney-Yang deficiency syndrome is a common geriatric disease that underlies chronic conditions such as diabetic nephropathy, chronic kidney disease, and osteoporosis. As age progresses, the kidney-Yang deficiency syndrome showcases increasingly pronounced manifestations, emerging as a key factor in the comorbidities experienced by elderly patients and affecting their quality of life and overall health status. Traditional Chinese medicine(TCM) has been extensively utilized in the treatment of kidney-Yang deficiency syndrome, with Epimedii Folium, Cinnamomi Cortex, and Lycii Fructus widely used in clinical settings. Despite the complexity of the molecular mechanisms involved in treating kidney-Yang deficiency syndrome, the potential therapeutic value of TCM remains compelling. Delving into the mechanisms of TCM treatment of kidney-Yang deficiency syndrome by regulating the neuro-endocrine-immune system can provide a scientific basis for targeted treatments of this syndrome and lay a foundation for the modernization of TCM. The pathophysiology of kidney-Yang deficiency syndrome involves multiple systems, including the interaction of the neuro-endocrine-immune system, the decline in renal function, the intensification of oxidative stress responses, and energy metabolism disorders. Understanding these mechanisms and their interrelationships can help untangle the etiology of kidney-Yang deficiency syndrome, aiding clinicians in making more precise diagnoses and treatments. Furthermore, the research on the specific applications of TCM in research on these pathological mechanisms can enhance the international recognition and status of TCM, enabling it to exert a greater global influence.

Background/Aims: The accuracy of endosonographers in diagnosing gastric subepithelial lesions (SELs) using endoscopic ultrasonography (EUS) is influenced by experience and subjectivity. Artificial intelligence (AI) has achieved remarkable development in this field. This study aimed to develop an AI-based EUS diagnostic model for the diagnosis of SELs, and evaluated its efficacy with external validation. Methods: We developed the EUS-AI model with ResNeSt50 using EUS images from two hospitals to predict the histopathology of the gastric SELs originating from muscularis propria. The diagnostic performance of the model was also validated using EUS images obtained from four other hospitals. Results: A total of 2,057 images from 367 patients (375 SELs) were chosen to build the models, and 914 images from 106 patients (108 SELs) were chosen for external validation. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the model for differentiating gastrointestinal stromal tumors (GISTs) and non-GISTs in the external validation sets by images were 82.01%, 68.22%, 86.77%, 59.86%, and 78.12%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in the external validation set by tumors were 83.75%, 71.43%, 89.33%, 60.61%, and 80.56%, respectively. The EUS-AI model showed better performance (especially specificity) than some endosonographers.The model helped improve the sensitivity, specificity, and accuracy of certain endosonographers. Conclusions We developed an EUS-AI model to classify gastric SELs originating from muscularis propria into GISTs and non-GISTs with good accuracy. The model may help improve the diagnostic performance of endosonographers. Further work is required to develop a multi-modal EUS-AI system.

OBJECTIVE: Here, we explored molecular changes that could potentially mediate healing effects of Gua Sha - a method employed by the Chinese traditional medicine with proven track records of safe and efficient applications dating back to ancient times as well as support from randomized controlled trials performed by modern medical studies - yet remaining almost entirely unexplored by the modern-day high-throughput methods of the -omics sciences. METHODS: We investigated transcriptome changes occurring shortly after Gua Sha treatment in the whole blood of healthy volunteers using bulk RNA-seq analysis. We applied various analytical tools to identify genes with consistent expression changes in multiple individuals in response to Gua Sha and their networks. RESULTS: We found that while the changes were very subtle and individual-specific, we could identify consistent upregulation of three histone genes. Further analysis of the potential regulatory networks of these histone genes revealed the enrichment of functions involved in the immune response and inflammation. CONCLUSION The significance of these results in the context of potential effects of Gua Sha and the next steps in exploring the molecular mechanisms of action of this technique are discussed.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

Background: The development of auditory and speech perception ability of children with hearing loss is affected by many factors after they undergo cochlear implantation (CI). Age at CI (CI age) appears to play an important role among these factors. This study aimed to evaluate the development of auditory and speech perception ability and explore the impact of CI age on children with prelingual deafness present before 3 years of age. Methods: Two hundred and seventy-eight children with pre-lingual deafness (176 boys and 102 girls) were included in this study, and the CI age ranged from 6 to 36 months (mean age, 19 months). Categorical auditory performance (CAP) was assessed to evaluate auditory ability, and the speech intelligibility rating was used to evaluate speech intelligibility. The evaluations were performed before CI and 1, 3, 6, 12, 18, 24, 36, 48, and 60 months after CI. Results: The auditory ability of the pre-lingually hearing-impaired children showed the fastest development within 6 months after CI (k = 0.524, t = 30.992, P < 0.05); then, the progress started to decelerate (k = 0.14, t = 3.704, P < 0.05) and entered a plateau at the 24th month (k = 0.03, t = 1.908, P < 0.05). Speech intelligibility showed the fastest improvement between the 12th and 24th months after CI (k = 0.138, t = 5.365, P < 0.05); then, the progress started to decelerate (k = 0.026, t = 1.465, P < 0.05) and entered a plateau at the 48th month (k = 0.012, t = 1.542, P < 0.05). The CI age had no statistical significant effect on the auditory and speech abilities starting at 2 years after CI (P < 0.05). The optimal cutoff age for CI was 15 months. Conclusions Within 5 years after CI, the auditory and speech ability of young hearing-impaired children continuously improved, although speech development lagged behind that of hearing. An earlier CI age is recommended; the optimal cutoff age for CI is at 15 months.

To investigate the prevalence of Candidatus Rickettsia barbariae in ticks from Xinjiang,total of 90 Rhipicephalus sanguineus and 420 Rhipicephalus turanicus were collected from Yuli area and the genes of ompA,ompB,gltA and 17kDa of Candidatus Rickettsia barbariae were detect with PCR.The target genes of ompA,ompB,gltA and 17kDa of Candidatus Rickettsia barbariae were detected from 10 Rh.sanguineus and 53 Rh.turanicus with rates as 11.11％ and 12.62％ respectively.The sequences obtained from these ticks were identical to the corresponding sequence in the positive samples.By BLAST analysis,the ompA,ompB partial sequences were 99.8％ (583/584) and 100％ (768/768) identical to the corresponding sequence of Candidatus Rickettsia barbariae strain from Rh.turanicus in Italy (EU272186.1,EU272187.1) respectively.The gltA and 17kDa partial sequence were also 100％ identical (375/375,356/356) to the corresponding sequence of Candidatus Rickettsia barbariae strain from Vermipsylla alakurt in Xinjiang (KT284716.1,KT284715.1).The manifestations of Candidatus Rickettsia barbariae occur in Rh.sanguineus and Rh.turanicus might suggest the potential health threat of the rickettsia organism to residents in Xinjiang area.

BACKGROUNDThe expression of dendritic cell-specific intercellular adhesion molecule 3-grabbing nonintegrin (DC-SIGN) in renal tubular epithelial cells has been thought to be highly correlated with the occurrence of several kidney diseases, but whether it takes place in renal tissues during hemorrhagic shock (HS) is unknown. The present study aimed to investigate this phenomenon and the inhibitory effect of Vitamin C (VitC).

METHODSA Sprague-Dawley rat HS model was established in vivo in this study. The expression level and location of DC-SIGN were observed in kidneys. Also, the degree of histological damage, the concentrations of tumor necrosis factor-μ and interleukin-6 in the renal tissues, and the serum concentration of blood urea nitrogen and creatinine at different times (2-24 h) after HS (six rats in each group), with or without VitC treatment before resuscitation, were evaluated.

RESULTSHS induced DC-SIGN expression in rat tubular epithelial cells. The proinflammatory cytokine concentration, histological damage scores, and functional injury of kidneys had increased. All these phenomena induced by HS were relieved when the rats were treated with VitC before resuscitation.

CONCLUSIONSThe results of the present study illustrated that HS could induce tubular epithelial cells expressing DC-SIGN, and the levels of proinflammatory cytokines in the kidney tissues improved correspondingly. The results also indicated that VitC could suppress the DC-SIGN expression in the tubular epithelial cells induced by HS and alleviate the inflammation and functional injury in the kidney.

Objective To explore the effects of maternal posturing and utilization of auxiliary facilities at early first stage of labor on primiparas′birth progress, pain degree and delivery mode. Methods Primiparas before delivery were randomly divided into control group and observation group. The primiparas in control group took free positions and received routine nursing care. Maternal posturing and auxiliary facilities were provided for the patients in observation group before first stage of labor. The birth progress, pain degree and delivery mode were compared between the two groups. Results The first, second and third stage of labor in observation group were significantly shorter than those of the control group, the differences were statistically significant ( P <0. 05). The difference of pain degree between two groups was statistically significant (P<0. 05). The natural delivery rate, the incidence of postpartum hemorrhage and asphyxia neonatorum were 78. 75%,8. 75% and 7. 50% in control group, while the natural delivery rate was 95. 00% and no postpartum hemorrhage or asphyxia neonatorum in observation group, and the differences were statistically significant (χ2 =9. 285 7,7. 179 5,6. 233 8, respectively;P<0. 05). Conclusions Early maternal posturing and utilization of auxiliary facilities can shorten the birth progress, relieve labor pain, improve the natural delivery rate and reduce adverse pregnancy outcome of primiparas.

OBJECTIVETo discuss the impacts of moxibustion for regulating spleen and stomach function on the survival quality of the patients of end stage renal disease (ESRD) with maintenance hemodialysis (MHD).

METHODSOne hundred and nine cases of uremia with MHD from 3 hemodialysis centers were randomized into an observation group (58 cases) and a control group (51 cases). The regular hemodialysis and conventional medication were used in the two groups. In the observation group, on the basis of the common treatment, moxibustion was applied to Zusanli (ST 36) and Sanyinjiao (SP 6), 2-3 times a day, the treatment of 4 weeks made one session. Totally, 3 sessions were required and the follow-up lasted for 3 months. KDQOL-SF (kidney disease quality of life short form,KDQOL-SFTM 1. 3) was adopted for the questionnaire investigation on survival quality before treatment, after treatment and at the end of follow-up separately in the two groups.

RESULTSAfter treatment, the survival quality scores in terms of physical functioning (83.62+/-13.27 vs 79.32+/- 22. 17), general health (58. 88+/- 20.24 vs 48.82+/-20.89) and vitality (77.07+/-15.56 vs 70. 59+/-22.61) in the observation group were higher than those in the control group (all P<0. 05). In comparison before and after treatment in the same group, the survival quality scores in terms of physical functioning, general health, vitality and symptoms/problems were all improved in the observation group (all P<0. 05). At the end of follow-up, the survival quality scores in terms of physical functioning, general health, mental health, social functioning, vitality, effects of kidney disease and cognitive function were higher in the observation group as compared with those in the control group (all P<0. 05). In comparison of the results at the end of follow-up with those before treatment, the survival quality scores in terms of vitality, symptoms/problems and cognitive function in the observation group were improved (all P< 0. 05). The differences were not significant in all of the 19 fields of survival quality evaluation before and after treatment, and after follow-up in the control group (all P>0. 05).

CONCLUSIONMoxibustion for regulating spleen and stomach function improves the survival quality of the patients with hemodialysis in terms of physical functioning, general health and vitality, which benefits the psychological condition of the patients, resulting in the improvements of the survival quality in the fields of mental health, social functioning, effects of kidney disease and cognitive function.

The aim of this study was to detect the expression level of eIF4E gene in patients with non-treated, remission and non-remission/relapse acute myeloid leukemia (AML), and other non-malignant haematologic diseases so as to analyze and reveal the relationship of eIF4E gene expression with AML progression. SYBR Green I RT-PCR was used to assay the expression level of eIF4E mRNA extracted from bone marrow mononuclear cells in 30 patients with AML (6 in M2, 5 in M3, 8 in M4, 10 in M5, 1 in M6) and 20 patients with non-malignant hematologic diseases. The β2-microglubin(β2M) was used as internal reference and the formula 2(-ΔCt)×100% was applied to calculate the expression level of eIF4E gene. The results showed that the eIF4E expression level (7.098 ± 5.544)% in patients with non-treated and non-remitted/relapsed AML was significantly higher than that in patients with remission (0.964 ± 0.312)% (P < 0.01) and non-malignant hematologic diseases (0.248 ± 0.163)% (P < 0.01). There was no difference between latter two group patients, even though the expression level of eIF4E gene in patients with M4 and M5 was higher. As compared with non-malignant hematologic diseases, the expression level of eIF4E gene of patients with remission patients showed no significant difference. It is concluded that the over-expression of eIF4E gene has been found in patients with AML, and its level obviously decreases along with remission of disease, thus the eIF4E gene may be a surveillance parameter for disease progression.
