Objective: To explore the characteristics of the diversity and composition of oral microbial flora with age, and to provide a reference for understanding the succession of oral microecology at different ages. Methods: Oral rinse 16S rRNA (V4 region) sequencing data from 9 021 participants 14-69 years of age in the 2009-2012 National Health and Nutrition Examination Survey (NHANES) were analyzed. Alpha diversity (Observed OTUs, Faith’s PD, Shannon Index), beta diversity (Bray-Curtis and UniFrac), and genus-level composition were examined using weighted generalized linear models (GLMs), including quadratic terms for age and adjusting for key covariates (gender, race/ethnicity, BMI, smoking status, and periodontitis severity). Results: Alpha diversity demonstrated a clear inverted U-shaped trajectory across age, peaking at 25-30 years old and declining thereafter. This trend remained consistent across sex, race, smoking, and periodontal health strata. Beta diversity analyses revealed a modest but steady age-related shift in community structure. Genus-level analyses revealed that Rothia, Prevotella_6, and Lactobacillus increased steadily with age, while Haemophilus, Porphyromonas, and Corynebacterium declined significantly. Notably, potential periodontopathogens, such as Fusobacterium and Treponema_2, peaked in early adulthood before declining with age. Conclusion Age is an important driver of oral microbial succession, and the oral microbiome exhibits dynamic changes across different life stages. Future longitudinal and multi-omic studies are warranted to elucidate the mechanisms underlying these age-related trajectories.

OBJECTIVE: To observe the clinical effect of Fu's subcutaneous needling based on anatomy train theory for nonspecific low back pain (NLBP). METHODS: A total of 120 patients with NLBP were randomized into an anatomy train Fu's subcutaneous needling group (40 cases, 3 cases dropped out), a conventional acupuncture group (40 cases, 2 cases dropped out) and a conventional Fu's subcutaneous needling group (40 cases, 2 cases dropped out). Acupuncture was applied at ashi points and bilateral Shenshu (BL23) and Dachangshu (BL25) in the conventional acupuncture group, once every other day, 3 times a week. Fu's subcutaneous needling was applied at lumbodorsal myofascial trigger points (MTrPs) in the Fu's subcutaneous needling group, once every 3 days, twice a week. On the basis of the treatment in the Fu's subcutaneous needling group, Fu's subcutaneous needling was applied at MTrPs along the posterior superficial line and lateral line in the anatomy train Fu's subcutaneous needling group, once every 3 days, twice a week. All groups were treated for 2 weeks. Before and after treatment, the scores of numeric rating scale (NRS) and Oswestry disability index (ODI) were observed, the distance of Schober test was measured and the endurance of trunk extensors was assessed in the 3 groups. RESULTS: After treatment, in the 3 groups, the NRS and ODI scores were decreased compared with those before treatment (P<0.05), the Schober test distance was increased compared with that before treatment (P<0.05), the static and dynamic muscle endurance was increased compared with that before treatment (P<0.05). After treatment, in the anatomy train Fu's subcutaneous needling group, the NRS and ODI scores were lower than those in the conventional acupuncture group and the conventional Fu's subcutaneous needling group (P<0.05), the Schober test distance was longer than that in the conventional acupuncture group and the conventional Fu's subcutaneous needling group (P<0.05), the static and dynamic muscle endurance was superior to that in the conventional acupuncture group and the conventional Fu's subcutaneous needling group (P<0.05). CONCLUSION Fu's subcutaneous needling based on anatomy train theory can effectively relieve the pain symptom, enhance quality of life, improve lumbar motion and lumbar muscle function in patients with NLBP.

Objective:To discusses the feasibility and clinical efficacy of the chimeric musculocutaneous flap pedicled with a superior gluteal artery perforator (SGAP) in treatment of Grade Ⅳ pressure sore around ischial tuberosity.Methods:A retrospective case study was conducted on 8 patients with Grade Ⅳ pressure sores around ischial tuberosity and treated in the Department of Plastic Surgery and Burns, the Affiliated Hospital of Zunyi Medical University from May 2019 to June 2023. The patients included 5 males and 3 females, aged 66.8 (40-78) years. All patients had paraplegia for 2 months to 10 years (mean, 59.2 months) and were complicated with hypoproteinemia. Two of the patients were also with sepsis. History of the Grade Ⅳ pressure sore was up to 1 month to 3.5 years (mean, 19.3 months). The sores were located on the right hip in 5 patients and left hip in 3 patients. The tissue defects of the pressure sore measured at 5 cm×5 cm to 6 cm×9 cm in size and all extended to the ischial tuberosity. Chimeric musculocutaneous flaps pedicled with a SGAP were used in the treatment of defect. The flap size ranged from 4 cm×8 cm to 7 cm×15 cm, and the muscular flap were at 8 cm×4 cm×2 cm to 14 cm×7 cm×5 cm in size. The muscular flaps were used to fill the cavities formed by the ulcer, while the flaps were used to cover the wounds. Donor and recipient site were sutured directly. The postoperative follow-ups were conducted at outpatient clinic and via telephone and WeChat interviews, and focused on evaluations of flap survival, complications, flap appearance and the recurrence of ulcer.Results:All the 8 flaps survived. All patients were included in the 3 to 16 months of postoperative follow-up, with 11.8 months in average. One flap had a partial edge split due to excessive pressure during negative pressure drainage, and healed after debridement and re-suture. Otherwise, the rest of 7 patients had primary healing at both the donor and recipient sites. All flaps had good appearance without ulceration, infection or recurrence of pressure sore.Conclusion:The chimeric musculocutaneous flap pedicled with SGAP offers a reliable blood supply, flexible rotation and sufficient tissue volume. It can be used to effectively reconstruct Grade Ⅳ pressure sore around ischial tuberosity with a reliable clinical effect.

Objective:To investigate the surgical technique and clinical outcomes of the tri-lobed chain medial plantar perforator flaps for reconstruction of soft tissue defects in palmar hand.Methods:A retrospective analysis was conducted on 6 patients (4 males and 2 females; aged 21-63 years with mean age of 39.2 years) who had soft tissue defects in palmar hands and were reconstructed with tri-lobed chain medial plantar perforator flaps in the Department of Plastic Surgery and Burns, the Affiliated Hospital of Zunyi Medical University between July 2024 and April 2025. All defects were located on palmar aspect of the injured hands. Following admission, debridement, fracture reduction and fixation and tendon repairs were carried out in primary surgery for 5 patients who had traumatic injuries with digital or metacarpal fractures and tendon ruptures, and stage-II surgery for soft tissue reconstruction was conducted at 7-9 days later. The patient with scar contracture received preoperative evaluation then followed by a scar excision and release surgery, prior to a reconstructive surgery for soft tissue defects. Four patients presented with multi-site defects, of whom, 1 patient had proximal phalangeal defects of index and middle fingers and a defect of metacarpophalangeal joint of ring finger, 1 patient had a defect of metacarpophalangeal joint of index finger and defects of proximal phalanges of middle and ring fingers, 1 patient had defects of proximal phalanges of index, middle and little fingers, and 1 patient had defects of proximal phalanges of middle, ring and little fingers. Of the patients with finger defects, the sizes of defect ranged from 2.0 cm ×1.8 cm to 6.0 cm×2.8 cm and the defects were reconstructed with individually harvested tri-lobed chain medial plantar perforator flaps. Two patients had soft tissue defects in palmar hands and they were measured at 6.0 cm×5.5 cm and 6.0 cm×7.0 cm in size. The palmar defects were reconstructed using combined tri-lobed chain flaps with the sizes of individual lobulated flap ranging from 2.1 cm×1.9 cm to 6.0 cm×2.9 cm. All foot donor sites were primarily closed with interrupted sutures. Postoperative management included routine anti-inflammatory, anticoagulant and antispasmodic treatment. Patients were discharged at 8-10 days after surgery and the postoperative follow-ups were conducted at outpatient clinic to monitor flap survival, contour, hand function, donor site healing, scar formation and foot function.Results:All flaps survived with primary healing of donor sites. Over the 1 to 9 (mean 6.1) months of postoperative follow-up, all flaps survived well with colour and thickness matching with the surrounding hand skin. At 6 months after surgery, two-point discrimination (TPD) of flaps achieved to 8-11 (mean 8.6) mm. According to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 4 patients achieved function recovery of fingers in excellent and 2 in good. Donor sites exhibited linear scars without painful scarring or paraesthesia, with normal ankle function and gaits.Conclusion:Tri-lobed medial plantar perforator flaps can be used to reconstruct soft tissue defects in palmar hand with primary and direct closure of the flap donor sites. They can simultaneously reconstruct multiple or a large defects, and provide satisfactory aesthetic and functional outcomes. It is a feasible surgical option.

Objective:In order to reduce the trauma associated with fetal cardiopulmonary bypass(F-CPB), Our team plans to develop a minimally invasive F-CPB through a small incision in the right axilla. The efficacy of this technique will be verified by using a big experimental animal model, thereby laying the foundation for fetal cardiac surgery supported by F-CPB in the future.Methods:Ten pregnant sheep were divided into F-CPB group(n=5) and control group(n=5). After fasting for 24 h, fetal lambs in the F-CPB group underwent a right axillary incision to establish F-CPB running for 1 h; The control group of fetal lambs only expose heart 1 h without F-CPB. Collect blood sample for laboratory test at the CPB vehicle before(T0), 30 min(T1), and 1 h after F-CPB running(T2) for the F-CPB group and through Superior Vena Cava before(T0), 30 min(T1), and 1 h after F-CPB running(T2) for the control group.Results:The blood routine indicators such as RBC, HCT, and Hb in the F-CPB group of fetal lambs decreased significantly during F-CPB, and their distribution showed significant statistical differences compared with the control group( P<0.05). There were no significant statistical differences in blood gas indicators such as pH, PO 2, PCO 2, and lactate concentration between the F-CPB group and the control group( P>0.05). There was no statistically significant difference in the concentration of cTnI in fetal lamb serum at each time point( P>0.05). There were significant statistical differences( P<0.05) in the distribution of fetal lamb Alb, γ-GGT, CK concentration and cholesterol concentration at various time points in the F-CPB group compared with the control group in liver function examination. In addition, the distribution of BUN in fetal lambs showed a significant difference between the two groups( P=0.006). Conclusion:A minimally invasive F-CPB via small incision in the right axilla is safe and feasible. The experimental animal model has demonstrated that this technique has minimal impact on the vital organ functions and internal environment of fetal lambs, thereby laying the foundation for clinical fetal cardiac surgery in the future.

Objective:To compare the efficacy of body posture combined with pharmacotherapy and pharmacotherapy alone in the treatment of chronic subdural hematoma(CSDH).Methods:Firstly, retrospective case series study was conducted. Thirty cases of CSDH that had received body posture combined with pharmacotherapy at Department of Neurosurgery, Huashan Hospital Affiliated to Fudan University from December 2016 to October 2020 were studied retrospectively. Twenty-seven patients were male, and 3 patients were female. The age of patients ( M(IQR)) was 66(16) years (range:28 to 84). Nineteen patients had unilateral hematoma, and 11 patients had bilateral hematoma. All patients received pharmacotherapy and body posture therapy that was to raise their lower limbs 20 to 30 cm with leg lift pad and get abdominal compressed with customized abdominal belt in supine position. Patients were required to maintain the body posture as much as possible, with the maximum to 16 to 18 hours per day. Patients with unilateral hematoma should tilt the head to the affected side and avoid tilting it to the opposite side. For patients with bilateral hematoma, there was no need for head lateralization. Patient were treated with oral dexamethasone and atorvastatin simultaneously. The preliminary efficacy of body posture combined with pharmacotherapy was determined by hematoma improvement rate which was analyzed by Clopper-Pearson method. Then, the multi-center, prospective, randomized controlled trial had carried out in 9 medical centers from August 2020 to November 2021. The stratified block randomization method was adopted. Patients were randomized in a ratio of 1∶1 to either receive pharmacotherapy alone(the control group) or body posture combined with pharmacotherapy(the experiment group) for 3 months and followed up for 6 months. Effective treatment was defined as complete absorption of hematoma, or the hematoma volume decreased by more than 10 ml and Markwalder grading scale score had improved by more than 1 point compared to the baseline. The efficacy rate and surgery conversion rate at 3 months and recurrence at 6 months were observed. Comparison between groups was performed with paired sample t test, Mann-Whitney U test, χ2 test, corrected χ2 test, or Fisher exact probability method. Logistic regression was used to compare the effective rate and operation rate between the two groups. Results:In the respective study, 30 patients completed follow-up 13 to 353 days after treatment. At the last follow-up, the incidence of almost complete absorption or significantly absorption of hematoma (hematoma volume was significantly reduced accompanied by symptom improvement) was 93.3%. The 95% CI for the incidence that analyzed by the Clopper-Pearson method was 77.9% to 99.2%. One hundred and six patients were enrolled in the multicenter study. Fifty-five patients underwent body posture combined with pharmacotherapy. The age was 74(17) years (range:26 to 92). Thirty-nine patients were males and 16 were females. Fifty-one patients underwent pharmacotherapy alone. The age was 69(12) years (range:48 to 84). Thirty-seven patients were males and 14 were females. The length of body posture recorded in diary card was (15.7±2.3) hours(range:7.6 to 19.3 hours). The efficacy rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 83.6% (46/55) and 56.9% (29/51), respectively at 3 months. The result of the logistic regression analysis showed that the efficacy of body posture combined with pharmacotherapy group was better than that of pharmacotherapy alone group ( OR=3.88,95% CI:1.57 to 9.58, P=0.003). Surgery rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 5.5% (3/55) and 21.6% (11/51) respectively. The result of Logistic regression showed that the pharmacotherapy alone group was more likely to be converted to surgery ( OR=0.21,95% CI:0.05 to 0.80, P=0.023). At the 6 months, no recurrence of cases was found in the body posture combined with pharmacotherapy group. However, the recurrence rate of pharmacotherapy alone group was 6.3% (3/48), there was no significant difference between the two groups ( P>0.05). Conclusion:The effect of body posture combined with pharmacotherapy for chronic subdural hematoma is better than that of pharmacotherapy alone.
