Finally， based on the literature analysis， the shortcomings of the current national standards were discussed， and relevant suggestions were put forward to further improve the national standards for dispensing granules. Through the overall analysis， it is helpful to comprehensively understand the technical characteristics of the national standards for TCM dispensing granules， and provide reference for the scientific exploration and practice of quality control methods for TCM.

Objective To explore the utility of comprehensive geriatric assessment (CGA) in screening risk factors for osteosarcopenia (OS) among older adults (≥80 years old) and to evaluate the therapeutic efficacy of CGA-guided integrated interventions for OS. Methods A total of 420 patients aged ≥80 years, recruited from the Department of Geriatrics, General Practice of The Affiliated Jiangyin Hospital of Nantong University, and community health centers from January 2022 to October 2024, were enrolled. Participants were classified into OS (n＝139) and non-OS (n＝281) groups based on diagnostic criteria. CGA was utilized to compare differences in general characteristics, laboratory indicators, comorbidities between groups. Binary logistic regression analysis identified independent risk and protective factors. Subsequently, 40 OS patients were randomly assigned to an intervention group (n＝20) receiving integrated interventions including nutritional support, exercise training, and psychological management or a control group (n＝20, receiving routine care). Appendicular skeletal muscle mass index (ASMI), grip strength, gait speed, and bone mineral density (BMD) T-score were compared between groups after 3 months. Results The prevalence of OS in this cohort was 33.1%. Compared to the non-OS group, the OS group exhibited significant differences in age, body mass index (BMI), smoking history, comorbidity index, concomitant medication, cognitive impairment, visual and hearing impairment, sleep disorders, depression, marital status, social participation, activities of daily living, nutritional risk, total cholesterol, uric acid, and constipation (P＜0.05). Logistic regression analysis identified age and comorbidity index as significant risk factors for OS, while BMI, married status, total cholesterol, and activities of daily living (assisted and independent) served as protective factors. The intervention group demonstrated significant improvements in grip strength, gait speed, BMD T-score, and male ASMI compared to controls (P＜0.05). Conclusions CGA demonstrates clinical utility in systematically identifying risk factors for OS in the old population. Multimodal interventions guided by CGA effectively improve musculoskeletal function in elderly OS patients.

AIM:To compare the differences and correlation of Spot vision screener and autorefractor in measuring preschool children refractive status under natural pupil conditions.METHODS: A cross-sectional study was conducted from October to November 2021. A total of 311 children from a senior kindergarten in Jiangyin city were randomly selected and underwent refraction test using both Spot vision screener and autorefractor without cycloplegia. The astigmatism was decomposed into J0 and J45 by the Thibos vector analysis. The differences in spherical equivalence(SE), sphere, cylinder, J0 and J45 measured by these two devices were compared using Wilcoxon signed rank test. Spearman analysis was employed to analyze the correlation.RESULTS:One child was excluded from the initial 311 children due to sphere power <-7.50 D, exceeding the detection range of the Spot vision screener(-7.50 to +7.50 D). A total of 310 children were ultimately included in this study, and the data of right eye of each child were selected. There was no statistically significant difference between the SE measured by the Spot vision screener and the autorefractor(P=0.598), while the difference in sphere, cylinder, J0, and J45 was statistically significant(all P<0.001). Measurements from these two devices had a positive correlation [SE(rs=0.350, P<0.001), sphere(rs=0.403, P<0.001), cylinder(rs=0.545, P<0.001), J0 (rs=0.672, P<0.001), J45 (rs=0.439, P<0.001)].CONCLUSION:The results of Spot vision screener and autorefractor cannot be replaced by each other, and different referral indicators should be set for these two devices in vision screening.

AIM: To discuss the impacts of pterygium excision combined with low-temperature plasma radiofrequency ablation and autologous conjunctival flap transplantation on tear film function, visual function, and recurrence rate in patients with pterygium.METHODS: A retrospective study was conducted on patients with pterygium who underwent surgery at Jiangyin Hospital of Traditional Chinese Medicine from March 2021 to January 2024. The patients were divided into two groups based on the surgical methods: the excision group with 50 cases(50 eyes)and the combined group with 51 cases(51 eyes). The excision group underwent pterygium excision, while the combined group received low-temperature plasma radiofrequency ablation and autologous conjunctival flap transplantation in addition to the excision. The tear film function [Schirmer's test(SⅠt), tear film break-up time(BUT)], visual quality, therapeutic effect, incidence of complications within 1 a, and recurrence rate were compared between the two groups before and after treatment.RESULTS: The general data of the two groups were comparable(P>0.05). After treatment, the SⅠt and BUT in the combined group were greater than those in the excision group(both P<0.001), while the corneal astigmatism and uncorrected visual acuity were lower than those in the excision group(both P<0.001). The initial treatment efficiency in the combined group(92%)was higher than that in the excision group(76%). Within 1 a, the recurrence rate(8% vs 22%)and complication rate(6% vs 24%)in the combined group were both lower than those in the excision group(both P< 0.05).CONCLUSION: The union of pterygium excision, low-temperature plasma radiofrequency ablation, and autologous conjunctival flap transplantation is beneficial for improving the efficacy, visual acuity, tear film function, and reducing recurrence rate in patients with pterygium.

A total of 23 components were identified by GC-MS， which were mainly 3，4，5-trimethoxy- methylbenzene， patchouli alcohol， Z-ligustilide and so on. CONCLUSIONS The characteristic chromatograms of the volatile oil in the standard decoction of Qingshang juantong decoction is established， and it is inferred that methyl eugenol， ligustilide， E- butylidenephthalide， patchouli alcohol， 3，4，5-trimethoxy-methylbenzene might be the main active components affecting the clinical therapeutic effect of the volatile oil of Qingshang juantong decoction.

Objective To explore the clinical effect and mechanism of Xianhecao-Baizhu in treatment of diarrhea irritable bowel syndrome with spleen deficiency and dampness type. Methods A total of 120 patients were randomly divided into treatment group and control group, with 60 cases in each group. The treatment group was given Xianhecao-Baizhu Decoction orally, and the control group was given pefican combined with montmorillonite powder orally. The course of treatment lasted for 1 month. The improvement of main symptoms, comprehensive efficacy, serum levels of 5-HT and IL-1β before and after treatment in two groups were observed. Results The improvement rate of abdominal distension or abdominal pain in the treatment group was higher than that in the control group (P < 0.05). The total effective rate of the treatment group was higher than that of the control group (P < 0.05). After treatment, serum 5-hydroxytryptamine (5-HT) and interleukin -1β(IL-1β) levels were decreased in both groups, but the decrease was more obvious in the treatment group than in the control group (P < 0.05). After treatment, abdominal pain scores and diarrhea scores in the two groups decreased, and the decrease in the treatment group was more obvious than that in the control group (P < 0.05). The scores of Hamilton Anxiety Scale (HAMA) and IBS Quality of Life Scale (IBS-QOL) in the two groups after treatment were decreased compared with those before treatment, and the HAMA and IBS-QOL scores in the treatment group were lower than those in the control group (P < 0.01). Conclusion Xianhecao-Baizhu can treat diarrhea irritable bowel syndrome with spleen deficiency and dampness type by reducing the secretion levels of 5-HT and IL-1β.

Objective To investigate the association between cerebral small vessel disease （CSVD） and mild cognitive impairment （MCI） in the elderly. Methods A total of 109 elderly patients who were diagnosed with MCI from March 2022 to February 2023 were enrolled as experimental group， and 89 healthy controls with normal cognitive function were enrolled as control group. Demographic data and general clinical data were collected from all subjects， and the onset of CSVD was evaluated based on cranial MRI findings. The two groups were compared in terms of baseline data， general clinical data， and CSVD manifestations. The ordered multi-classification logistic regression model was used to identify the independent influencing factors for MCI in the elderly. Results There were 109 patients with MCI and 89 controls in this study. Compared with the experimental group， the control group had significantly longer education years， a significantly better economic status， a significantly higher degree of participation in social activities， and a significantly lower alcohol consumption rate （P<0.05）. There were 90 subjects （82.57%） in the experimental group and 62 （69.66%） in the control group who had different CSVD phenotypes. The experimental group had significantly higher detection rates of LI and moderate-to-severe WMH than the control group （P<0.05）， while there were no significant differences between the two groups in the detection rates of moderate-to-severe EPVS and CMB （P>0.05）. There were significant differences between the two groups in the total load score of CSVD and the total load degree of CSVD （P<0.05）. The logistic regression analysis showed that education years， participation in social activities， detection rate of CSVD， moderate-to-severe WMH， total load score of CSVD， and total load degree of CSVD were independent influencing factors for MCI in the elderly. Conclusion There is an increase in the detection rate of CSVD in the elderly patients with MCI， especially LI and moderate-to-severe WMH. The total load score of CSVD and the total load degree of CSVD are independently associated with MCI in the elderly.

【Objective】 To explore the diagnosis, treatment and prognosis of renal cell carcinoma (RCC) patients with Stauffer syndrome. 【Methods】 The clinicopathological and follow-up data of 17 RCC patients with Stauffer syndrome who underwent operation during Sep.2014 and Aug.2019 were retrospectively analyzed. The survival was analyzed with Kaplan-Meier curve and log-rank, and related factors affecting the prognosis were determined with univariate and multivariate Cox regression model. 【Results】 The pathological results included clear cell RCC in 14 cases, papillary RCC in 2 cases, and poorly differentiated tissue in 1 case. The liver function recovered within 3 months after operation in 5 cases, within 6 months in 3 cases, within 1 year in 4 cases, and did not recover in 3 cases. During the follow up of 6 to 72 (average 54.1) months, the 1-, 3-, and 5-year survival rates were 88.2% (15/17), 76.5% (13/17) and 52.9% (9/17), respectively. Survival analysis showed that the cancer-specific survival (CSS) of RCC patients with Stauffer syndrome was low, and tumor size, AJCC stage, lymph node metastasis and Stauffer syndrome were predictors of poor prognosis. 【Conclusion】 The prognosis of RCC patients with Stauffer syndrome is poor, and early surgical intervention should be conducted. The liver function of most patients can return to normal gradually after surgery. Continuous examination of liver function has significant meaning for tumor recurrence, metastasis and prognosis.

The study aims to explore the effect of mesenchymal stem cells-derived exosomes (MSCs-Exo) on staurosporine (STS)-induced chondrocyte apoptosis before and after exposure to pulsed electromagnetic field (PEMF) at different frequencies. The AMSCs were extracted from the epididymal fat of healthy rats before and after exposure to the PEMF at 1 mT amplitude and a frequency of 15, 45, and 75 Hz, respectively, in an incubator. MSCs-Exo was extracted and identified. Exosomes were labeled with DiO fluorescent dye, and then co-cultured with STS-induced chondrocytes for 24 h. Cellular uptake of MSC-Exo, apoptosis, and the protein and mRNA expression of aggrecan, caspase-3 and collagenⅡA in chondrocytes were observed. The study demonstrated that the exposure of 75 Hz PEMF was superior to 15 and 45 Hz PEMF in enhancing the effect of exosomes in alleviating chondrocyte apoptosis and promoting cell matrix synthesis. This study lays a foundation for the regulatory mechanism of PEMF stimulation on MSCs-Exo in inhibiting chondrocyte apoptosis, and opens up a new direction for the prevention and treatment of osteoarthritis.

OBJECTIVE: To explore the trend of changes in the parameters of the spine-pelvic sagittal plane before and after surgery in patients with double-segment lumbar spondylolisthesis (LSL) and to evaluate the value of the surgical effect. METHODS: A retrospective analysis of 95 double-segment lumbar spondylolisthesis patients treated with posterior lumbar interbody fusion from October 2019 to October 2020 were analyzed, including 31 males and 64 females;age ranging from 41 to 63 years old, with an average of (52.10±4.35) years old;degree of lesion, 47 patients with gradeⅠand 48 patients with gradeⅡ. The surgical efficacy was evaluated according to the Oswestry dysfunction index(ODI) improvement rate at 3 months after operation. ODI improvement rate ≥50% was considered good, and <50% was considered bad. Ninety-five patients were divided into good curative effect group (74 cases) and poor curative effect group (21 cases) according to surgical curative effect. The clinical data, such as gender, age, body mass index, course of disease, degree of disease, operation time, intraoperative blood loss, and comorbidities were compared between two groups were compared. The parameters of spine pelvis sagittal plane were observed before and 3 months after operation, including spine sacral angle (SSA), T1 pelvic angle (TPA), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS). Clinical symptoms were evaluated using visual analogue scale (VAS) and ODI. The correlation between the changes of spine pelvis sagittal plane parameters and the changes of VAS and ODI before and after surgery were analyzed, and the value of spine pelvis sagittal plane parameters in evaluating the surgical efficacy of patients with double level lumbar spondylolisthesis at 3 months after surgery was evaluated. RESULTS: The courses of disease and surgical time in the group with poor efficacy were longer than those in the group with good efficacy, and the degree of lesion was higher in the group with poor efficacy (P<0.05). The SSA, TPA, LL, and SS of the group with good efficacy were higher than those of the group with poor efficacy before and 3 months after surgery, while the PT was lower than that of the group with poor efficacy (P<0.05). The changes in SSA, TPA, LL, PT, and SS before and after surgery in the group with good efficacy were greater than those in the group with poor efficacy (P<0.05). The VAS and ODI of both groups were lower at 3 months after surgery than before, and the group with good efficacy was lower(P<0.05). The changes in VAS and ODI before and after surgery in the group with good efficacy were greater than those in the group with poor efficacy (P<0.05). The changes in SSA, TPA, LL, PT, SS before and after surgery were positively correlated with the changes in VAS and ODI (P<0.05). Three months after surgery, SSA, TPA, LL, PT, and SS were used to evaluate the surgical efficacy of patients with dual level lumbar spondylolisthesis. The area under the curve (AUC) was 0.868, 0.797, 0.875, 0.822, and 0.853, respectively. The combined evaluation of all indicators resulted in the highest AUC, 0.927, and the best sensitivity and specificity were 90.50% and 91.89%, respectively. CONCLUSION The spine pelvis sagittal plane parameters SSA, TPA, LL, and SS of patients with double level lumbar spondylolisthesis before and after surgery show an upward trend;PT shows a downward trend;PI do not change significantly. And the changes of SSA, TPA, LL, SS, and PT are closely related to the patient's pain level and the improvement of lumbar function, which can be used as parameters to evaluate the surgical efficacy.
