Objective To evaluate the clinical efficacy of Shenshi Jiangzhuo Formula(composed of Poria,Atractylodis Rhizoma,Magnoliae Officinalis Cortex,Pinelliae Rhizoma Praeparatum,Aurantii Fructus Immaturus,Arecae Semen,Talcum,Tetrapanacis Medulla,Notoginseng Radix et Rhizoma,Paeoniae Radix Rubra,Rubiae Radix et Rhizoma,Broussonetiae Fructus,etc.)in treating non-alcoholic fatty liver disease(NAFLD)with phlegm blended with stasis syndrome.Methods A total of 76 NAFLD patients with phlegm blended with stasis syndrome from the Seventh School of Clinical Medicine,Guangzhou University of Chinese Medicine(Shenzhen Bao'an Traditional Chinese Medicine Hospital)were enrolled between February 2024 and December 2024.The patients were randomly assigned(via random number table)to either the trial group(n=38,treated with Silibinin Meglumine Tablets plus Shenshi Jiangzhuo Formula)or the control group(n=38,treated with Silibinin Meglumine Tablets alone)for 8 weeks.The changes in liver controlled attenuation parameter(CAP),liver function markers[alanine aminotransferase(ALT),aspartate aminotransferase(AST),gamma-glutamyl transferase(GGT)],lipid profiles[triglycerides(TG),total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C)],and traditional Chinese medicine(TCM)syndrome scores were observed before and after treatment.Clinical efficacy and safety were evaluated.Results(1)One case dropped out from each group during the study and 37 cases in each group were included for final statistics.(2)After 8 weeks of treatment,the overall response rate in the trial group was 94.59％(35/37),compared with 62.16％(23/37)in the control group.Intergroup comparison revealed that the trial group demonstrated significantly superior overall therapeutic efficacy(by rank-sum test)and overall response rate(by chi-square test)compared with the control group(P＜0.01).(3)Both groups showed improved CAP values after treatment,and the trial group demonstrated significantly greater improvement compared to the control group(P＜0.01).(4)Post-treatment improvements in alanine aminotransferase(ALT),aspartate aminotransferase(AST),and gamma-glutamyl transferase(GGT)were improved in both groups(P＜0.01),with the trial group showing significantly superior improvements(P＜0.05 or P＜0.01).(5)Triglycerides(TG),total cholesterol(TC),and low-density lipoprotein cholesterol(LDL-C)were improved in both groups after treatment,and the trial group exhibited significantly better outcomes(P＜0.01).(6)Both groups presented reduced TCM syndrome scores after treatment,and the trial group showed greater reduction(P＜0.01).(7)No significant adverse recations were observed in both groups,showing high safety.Conclusion Integrative therapy with Shenshi Jiangzhuo Formula exerts certain effects in improving CAP values,liver function,lipid metabolism,and TCM symptoms in NAFLD patients with phlegm blended with stasis syndrome,demonstrating robust clinical value.

AIM:To explore the relationship between the amplitude of diurnal variations in the choroidal vascular index(CVI)and annual changes in spherical equivalent(SE)and axial length in school-aged children.METHODS: Prospective study. Totally 39 cases(39 eyes)of Chinese school-age children aged 7 to 12 that diagnosed as emmetropia and myopia and error of refraction at optometry clinics of Eye Hospital, Wenzhou Medical University from July to August 2021 were selected. While 33 cases(33 eyes)were finally included, with 6 cases of loss to 1 a follow-up. A total of 16 cases(16 eyes)with annual growth of SE<0.5 D and 17 cases(17 eyes)with annual growth of SE≥0.5 D were divided into a non-progression group and progression group, respectively. Swept-source optical coherence tomography(SS-OCT)and custom choroidal analysis software were used to longitudinally observe diurnal variations in CVI of subjects, and the association between CVI diurnal amplitude and annual changes in SE and axial length was analyzed.RESULTS:It showed no significant correlation between the CVI diurnal amplitude at 1 mm from the fovea and annual changes in SE of the non-progressive group(P=0.65), while in the progression group, the CVI diurnal amplitude at 1 mm from the fovea was negatively correlated with annual changes in SE(P=0.048). However, no significant correlation was identified between CVI diurnal amplitude and annual changes in axial length in either group(all P>0.05). The diurnal amplitude of the CVI at the 1 mm foveal center had an effect on annual SE progression(P=0.039). Conversely, the diurnal amplitude of axial length, the annual changes in axial length, and the maximum or minimum time of CVI demonstrated significant associations with SE progression(all P> 0.05).CONCLUSION: Diurnal variations in CVI amplitude are associated with SE progression in school-aged children, providing a basis for further understanding the choroid-related changes in the process of myopia onset and progression.

An ideal dermal filler should integrate filling, repair, and anti-aging effects, with immediate tissue augmentation, slow degradation, and progressive stimulation of collagen regeneration. However, commonly used hyaluronic acid (HA) hydrogels, while effective for rapid filling, suffer from limited duration of support, weak cell adhesion, and an inability to promote collagen regeneration. Silk fibroin (SF), a natural protein from silkworm cocoons, is known for its excellent cell adhesion and collagen-stimulating abilities. However, its limited gelation capability restricts its potential application as a standalone injectable hydrogel. Based on a complementary strategy, this study combines the rapid gelling properties of HA with the collagen regenerative properties of SF to create a co-crosslinked HA-SF hydrogel. The composite hydrogel merges HA's rapid filling effect with SF's strong tissue adhesion and collagen-stimulating abilities. The formulation, physicochemical properties, degradation, biocompatibility, and filling effects of the HA-SF hydrogel were systematically investigated. HA-SF hydrogel exhibits excellent mechanical properties and ensures long-term support while maintaining injectability. Interestingly, after intradermal injection in the UVB-induced photoaging model, HA-SF hydrogel not only enhances hydrogel-cell interaction but also continues to stimulate collagen regeneration, especially type III collagen. This dual action achieves the biological effects of repair and anti-aging while maintaining the filling effect. Proteomic analysis confirms that repair and anti-aging effects are enhanced by the regulation of skin fibroblasts and modulation of amino acid and lipid metabolism. This composite hydrogel holds strong promise for clinical applications, offering a safer, long-lasting, and more natural injectable filler that combines filling, repair, and anti-aging into one system.

Objective:To investigate the early clinical outcomes of anterior cervical discectomy and fusion (ACDF) in the treatment of two-segment cervical spondylotic myelopathy (CSM) using a cervical soft endoscopic minimally invasive system.Methods:A retrospective follow-up study was conducted on the medical records of 23 patients with two-segment cervical myelopathy who underwent ACDF using a soft endoscopic cervical spine minimally invasive system at the Third Affiliated Hospital of Southern Medical University between October 2022 and December 2023. The cohort included 15 males and 8 females, aged 37-79 years (58.52±11.77 years). The affected cervical segments included: C 3, 4 and C 4, 5 in 2 cases; C 3, 4 and C 5, 6 in 3 cases; C 4, 5 and C 5, 6 in 10 cases; C 5, 6 and C 6, 7 in 7 cases; and C 4, 5 and C 6, 7 in 1 case. Clinical outcomes were evaluated based on the Japanese Orthopaedic Association (JOA) scores and visual analog scale (VAS) for neck and shoulder pain, assessed preoperatively and at 1 week, 1 month, and 3 months postoperatively. Additional data recorded included incision length, intraoperative blood loss, operative time, postoperative complications, and the presence of prevertebral soft tissue edema. The improvement rate of JOA scores at the final follow-up was also calculated. Results:All patients successfully underwent surgery and completed follow-up, with follow-up durations ranging from 3 to 6 months (4.01±0.98 months). The mean operative time was 80.09±22.66 min (range: 53-127 min), and the mean incision length was 3.25±0.32 cm (range: 3-4 cm). Estimated blood loss ranged from 10 to 100 ml, with a mean of 34.78±24.1 ml. Postoperative drainage ranged from 0 to 80 ml (mean: 23.13±26.1 ml), and postoperative hospitalization durations ranged from 4 to 12 days (6.83±2.59 days). JOA scores improved significantly from a preoperative median of 9.00(8.00, 10.00) to 12.00(11.00, 14.00) at 1 week, 13.00(12.00, 14.00) at 1 month, and 15.00(15.00, 16.00) at 3 months postoperatively (χ 2=220.492, P<0.001). VAS scores for neck and shoulder pain also improved significantly from a preoperative median of 5.00(4.00, 6.00) to 3.00(2.00, 3.00) at 1 week, 2.00(2.00, 3.00) at 1 month, and 2.00(1.00, 2.00) at 3 months postoperatively (χ 2=170.869, P<0.001). No postoperative complications such as dysphagia, hoarseness, nerve injury, cerebrospinal fluid leakage, or intraspinal hematoma were observed. Imaging revealed no significant prevertebral soft tissue edema. At the final follow-up, the improvement rate of JOA scores resulted in 14 cases rated as excellent and 9 as good. Conclusions:ACDF using a cervical soft endoscopic minimally invasive system demonstrates satisfactory clinical outcomes for the treatment of two-segment CSM. This technique reduces the incidence of common complications associated with both open and traditional endoscopic surgeries.

Peritoneal dialysis (PD) is a crucial renal replacement therapy for end-stage renal disease (ESRD), offering significant advantages as high flexibility, hemodynamic stability, and high cost-effectiveness. However, prolonged exposure to intra-abdominal dialysate may predispose to the mechanical complication of abdominal external hernia. Abdominal external hernia may lead to various adverse clinical outcomes. In severe cases, it can progress to incarceration or even rupture, ultimately necessitating discontinuation of the therapy. The authors systematically review PD-associated abdominal external hernias, including their clinical landscape, risk factors, surgical treatment strategies and prognostic determinants. They also assess the effects of hernia repair on residual renal function, aiming to provide references for clinical decision-making.

  Objective  To investigate the needs of eight-year program clinical medical students for the organization and contents of clinical oncology courses.  Methods  From September to November 2020, a questionnaire survey was conducted among eight-year program clinical medicine students in Peking Union Medical College to find out their knowledge base in oncology, teaching mode preference and course contents of interest.  Results  A total of 122 students participated in the survey, in which 89.3%(109/122) of the students showed interest in basic and clinical research projects related to oncology, 84.4%(103/122) thought it was better to use Simulation-based medical education (SBME), and 91.0%(111/122) hoped to learn throughoff-line discussion. In terms of course contents, eight-year program medical students were more interested in knowledge directly related to clinical context, such as diagnosis, treatment, multidisciplinary comprehensive treatment and evidence-based medicine. In terms of sub-analysis, traditional eight-year students (86%, 92/107) showed a higher acceptance of palliative care than students in the 4+4 reform program(60%, 9/15) and were more willing to act as scriptwriters in SBME(26% vs. 7%, P=0.013). The students in clinical phase gained a better understanding of oncology knowledge through research training and were more inclined to take on the role of scriptwriters in SBME than those in basic phase (27% vs. 11%, P=0.048).  Conclusions  The eight-year program clinical medical students are interested in the clinical oncology course and prefer study in the form of Simulation-based medical education (SBME).

OBJECTIVE: To carry out prenatal diagnosis and genetic analysis for a fetus with disorders of sex development (DSDs). METHODS: A fetus with DSDs who was identified at the Shenzhen People's Hospital in September 2021 was selected as the study subject. Combined molecular genetic techniques including quantitative fluorescence PCR (QF-PCR), multiplex ligation-dependent probe amplification (MLPA), chromosomal microarray analysis (CMA), quantitative real-time PCR (qPCR), as well as cytogenetic techniques such as karyotyping analysis and fluorescence in situ hybridization (FISH) were applied. Ultrasonography was used to observe the phenotype of sex development. RESULTS: Molecular genetic testing suggested that the fetus had mosaicism of Yq11.222qter deletion and X monosomy. Combined with the result of cytogenetic testing, its karyotype was determined as mos 45,X[34]/46,X,del(Y)(q11.222)[61]/47,X,del(Y)(q11.222),del(Y)(q11.222)[5]. Ultrasound examination suggested hypospadia, which was confirmed after elective abortion. Combined the results of genetic testing and phenotypic analysis, the fetus was ultimately diagnosed with DSDs. CONCLUSION This study has applied a variety of genetic techniques and ultrasonography to diagnose a fetus with DSDs with a complex karyotype.
