This paper systematically reviews the core concepts and lines of theoretical inheritance of major spleen-stomach theories in traditional Chinese medicine （TCM）， including spleen deficiency theory， spleen-stomach damp-heat theory， and liver-spleen disharmony theory. It is found that these theories have all undergone a developmental trajectory characterized by classical foundation， refinement of therapeutic methods， systematization of pathogenesis， and modern innovation. The evolution of spleen-stomach theory has achieved a shift from a singular focus on tonifying the spleen to regulating dynamic middle-jiao （焦） balance， and from localized spleen-stomach regulation to the circular movement of qi involving all five zang organs. In terms of modern disease-syndrome integrative research， spleen deficiency syndrome is shown to be closely associated with impairment of the gastrointestinal mucosal barrier， metabolic disorders， and gene polymorphisms related to Helicobacter pylori-associated gastric diseases. Spleen-stomach damp-heat syndrome is closely linked to hyperactive energy metabolism， inflammatory cytokines， and abnormal expression of aquaporins. Liver-spleen disharmony syndrome is mainly associated with dysregulation of the brain-gut axis and microbiota-related metabolic disorders. It is proposed that future research on spleen-stomach diseases and syndromes should further elucidate their potential multidimensional differential biological characteristics， thereby promoting the modernization of the TCM discipline of spleen-stomach studies.

Objective: To evaluate the intervention effect of school based salt reduction health education, so as to provide a scientific basis for constructing a more effective and sustainable salt reduction intervention model for children. Methods: According to a randomized controlled trial design, in June 2022, probability proportional to size sampling was used to select 501 second grade students (248 in the control group and 253 in the intervention group) from 10 primary schools in Zhenjiang (intervention group) and 10 primary schools in Yangzhou (control group), Jiangsu Province. An one year school based salt reduction health education intervention was implemented. This included 20 online and 8 offline health education sessions, monitoring of salt consumption in the canteen, and the establishment of a salt reduction environment on campus. The control group received no additional salt reduction interventions. A questionnaire survey and 24 hour urinary sodium test were conducted before and after the intervention. The difference in differences method was used to evaluate the intervention effect. Results: After the intervention, the intervention group showed significant net intervention effects in knowledge aspects, including knowing that primary school students consume less salt than adults ( OR=3.55,95%CI =1.69-7.47), daily salt intake of primary school students ( OR=6.64,95%CI =3.71-11.87), long term high salt intake leading to hypertension ( OR=6.83,95%CI =3.93-11.91), low salt intake not causing hair graying ( OR= 1.66 ,95%CI =1.00-2.75), salt content in food labels ( OR=4.56,95%CI =2.63-7.91), and common high salt foods ( OR=3.39,95%CI =1.87-6.14) (all P <0.05). In terms of attitude, the net intervention effect for having a positive attitude toward using less salt in home cooking was significantly increased ( OR=1.88,95%CI =1.13-3.12, P <0.05). There were no statistically significant net intervention effects for salt reduction related behaviors (all P >0.05). There was no statistically significant difference in the changes of 24 hour urinary sodium between the intervention group and the control group before and after intervention ( P >0.05). Conclusions School based salt reduction health education effectively improves students salt reduction knowledge and attitudes but has a limited effect on behavior change. The home-school collaboration should be strengthened, and the dietary environment should be optimized simultaneously.

OBJECTIVE To explore the pharmacokinetic characteristics of 3 blood-absorbed components of Xiangshao sanjie oral liquid in rats with hyperplasia of mammary gland （HMG）. METHODS Female SD rats were divided into control group and HMG group according to body weight， with 6 rats in each group. The HMG group was given estrogen+progesterone to construct HMG model. After modeling， two groups were given 1.485 g/kg of Xiangshao sanjie oral liquid （calculated by crude drug） intragastrically， once a day， for 7 consecutive days. Blood samples were collected before the first administration （0 h）， and at 5， 15， 30 minutes and 1， 2， 4， 8， 12， 24 hours after the last administration， respectively. Using chlorzoxazone as the internal standard， the plasma concentrations of ferulic acid， paeoniflorin and rosmarinic acid in rats were detected by UPLC-Q/TOF-MS. The pharmacokinetic parameters [area under the drug time curve （AUC0－24 h， AUC0－∞）， mean residence time （MRT0－∞）， half-life （t1/2）， peak time （tmax）， peak concentration （cmax）] were calculated by the non-atrioventricular model using Phoenix WinNonlin 8.1 software. RESULTS Compared with the control group， the AUC0－24 h， AUC0－∞ and cmax of ferulic acid in the HMG group were significantly increased （P＜0.05）； the AUC0－24 h， AUC0－∞ ， MRT0－∞ ， t1/2 and cmax of paeoniflorin increased， but there was no significant difference between 2 groups （P＞0.05）； the AUC0－24 h and MRT0-∞ of rosmarinic acid were significantly increased or prolonged （P＜0.05）. C ONCLUSIONS In HMG model rats， the exposure of ferulic acid， paeoniflorin and rosmarinic acid in Xiangshao sanjie oral liquid all increase， and the retention time of rosmarinic acid is significantly prolonged.

It is believed that the basic mechanism of cough associated with interstitial lung disease is collaterals deficiency with latent wind： the deficiency of the lung organs and lung collaterals is the basis of its pathogenesis， and latent wind in lung collaterals is the key mechanism of the cough which is difficult to cure. Treatment is based on the principle of supplementing deficiency and treating wind， dispelling the pathogens and unblocking the collaterals. Supplementing deficiency should supplement lungs， boost kidneys， and strengthen spleens to consolidate the root and banking up the origin， and regulate and tonify the lung collaterals； dispelling the pathogens should treat the internal and external winds at the same time， and taking into account the combined pathogens of phlegm， stasis and dampness to clear the stagnation of the lung collaterals.

Objective This study aims to use subjective and objective evaluation indicators to accurately calculate the relative weights of various factors that affect blood glucose control in gestational diabetes and provide scientific basis for the formu-lation of clinical nutrition intervention plans and support for the evaluation of blood sugar intervention effects in the late stage of pregnancy.Methods The fuzzy analytic hierarchy process(FAHP)was used to construct a hierarchical model of nutrition man-agement for patients with gestational diabetes,calculate the weights of each criterion layer in detail,and integrate them with the weight adjustment coefficients of scoring experts to form a mathematical model for nutrition management of gestational diabetes.Results Based on 14 valid expert feedback questionnaires,the relative weights of the first,second,and 29 end indicators were calculated.The weights of the first indicators were nutrition assessment indicators for gestational diabetes(0.34142105),formu-lation of nutrition management plans for gestational diabetes(0.331055183),and implementation of nutrition management plans(0.327923333).The largest weights in the second indicators were laboratory indicators(0.110385024)and meal plans(0.117342182).Conclusion The fuzzy analytic hierarchy process can accurately estimate the relative weights of factors affect-ing personalized nutrition management in gestational diabetes,providing a theoretical basis for blood sugar management during the entire pregnancy.

Objective:To investigate the occurrence of work-related musculoskeletal disorders (WMSDs) in bus drivers in Zhuhai City, analyze the ergonomic factors, and explore the prevention and control measures of WMSDs.Methods:From March to May 2023, 1675 active bus drivers from 5 branches of a bus group in Zhuhai were selected by stratified sampling method. The incidence of WMSDs among bus drivers in the past 12 months was investigated by using the modified Chinese Version of Musculoskeletal Disorders Questionnaire. The influencing factors of WMSDs were analyzed by χ2 test and generalized linear model. Results:The total incidence of WMSDs in bus drivers in the past 12 months was 47.2% (790/1675) , and the incidence of WMSDs in neck and shoulder and lower back was 36.9% (618/1675) and 31.7% (531/1675) , respectively. The χ2 test showed that there were statistically significant differences in the incidence of WMSDs among bus drivers with different individual factors such as body mass index (BMI) , physical exercise and looking down at mobile phones ( P<0.05) . There were significant differences in the incidence of WMSDs in the neck and shoulder of bus drivers with different years of service and number of stops on their routes ( P<0.05) . There were statistically significant differences in the incidence of WMSDs in the lower back of bus drivers with different one-way driving time, shift patterns, and rest breaks during work ( P<0.05) . Abnormal BMI, professional working years >12 years, uncomfortable working posture, frequent turning, slightly forward neck posture, large forward neck posture and long shoulder posture were the risk factors for WMSDs of bus drivers ( P<0.05) , and comfortable seat was the protective factor ( P<0.05) . One-way driving time >70 min, shift work schedules, uncomfortable working posture, slightly forward back posture, and frequent turning were the risk factors leading to lower back WMSDs ( P<0.05) , and physical exercise, comfortable driving cabin space, and seat comfort were the protective factors ( P<0.05) .

Objective:To analyze the genetic characteristics of clinical manifestations in children with KBG syndrome due to microdeletions.Methods:A retrospective case summary was conducted. Four children diagnosed with KBG syndrome due to 16q24.3 microdeletion at Children′s Hospital of Zhengzhou University from July 2021 to April 2024 were enrolled.Their clinical manifestations, biochemical parameters, imaging data, whole-exome sequencing results, treatments and follow-up outcomes were reviewed.Results:The cohort included two males and two females (diagnosed at 81, 18, 26, and 56 months of age, respectively), from four unrelated families. All patients exhibited peculiar facial features (Cupid′s bowed-shaped lips, prominent ears, thick eyebrows), skeletal abnormalities (brachydactyly, abnormal ribs, short stature, etc.), ocular anomalies (astigmatism, strabismus, amblyopia, etc.), intrauterine growth restriction, and developmental retardation. Case 2, 3, 4 had cranial imaging abnormalities, including thin anterior pituitary lobes with pineal cyst, left ventricular cyst, and abnormal pituitary stalk or lateral ventricles with sinusitis, respectively. Two children had intellectual disability, two had congenital heart disease, and one had delayed bone age and hair abnormalities. Whole exome genomic sequencing confirmed 16q24.3 microdeletions encompassing ANKRD11 gene in all four cases. Two children treated with recombinant human growth hormone achieved height increments of 1.5 s and 0.4 s, respectively. Conclusions:Typical features of 16q24.3 microdeletion-induced KBG syndrome include peculiar facial features, macrodontia, skeletal anomalies, neurological abnormalities, and ocular defects. Genetic testing is essential for definitive diagnosis. The treatment of KBG syndrome requires early diagnosis and multidisciplinary collaboration to implement individualized treatment for multisystem symptoms.
