Objective To explore the safety and efficacy of thoracoscopy-guided thoracic paravertebral block (TPVB) in thoracoscopic pulmonary resection, and to provide strategies for enhanced recovery after surgery (ERAS) in thoracoscopic lung resection. Methods Patients who underwent thoracoscopic pulmonary resection (including sublobar resection and lobectomy) in the 987th Hospital of Joint Logistics Support Force of People's Liberation Army, General Hospital of Central Theater Command of the People’s Liberation Army, and the First Affiliated Hospital with Nanjing Medical University between May 2021 and June 2023 were prospectively enrolled. The patients were randomly allocated into three groups in a single-blind manner using a random number table. Group A (incisional nerve block group) received a subcutaneous injection of ropivacaine (0.375%, 2 mg/kg) around the incision during chest closure. Group B (ultrasound-guided TPVB group) received an ultrasound-guided injection of ropivacaine (0.375%, 2 mg/kg) at the paravertebral space after chest closure. Group C (thoracoscopy-guided TPVB group) received a thoracoscopy-guided intrathoracic injection of ropivacaine (0.375%, 2 mg/kg) at the paravertebral space during chest closure. Perioperative adverse drug reactions, pain scores, postoperative analgesic consumption, and postoperative length of hospital stay were compared among the three groups. Results A total of 180 patients were included, comprising 108 females and 72 males, with a mean age of (62.15±7.36) years. There were no statistical differences among the three groups in baseline characteristics, including age, weight, gender, prevalence of comorbidities, operative time, number of surgical incisions, number of chest tubes, or intraoperative dosages of sufentanil and propofol (P>0.05). No adverse anesthesia events occurred during surgery in any of the groups. The pressing frequency of the patient-controlled intravenous analgesia (PCIA) pump, Visual Analogue Scale (VAS) pain scores, the rate of postoperative rescue analgesic use, and the incidences of postoperative cough and dizziness in the group C were significantly lower than those in the other two groups (P<0.05). The postoperative length of hospital stay in the group B and group C was significantly shorter than that in the group A (P<0.05). Conclusion Thoracoscopy-guided TPVB during chest closure can effectively alleviate postoperative pain without increasing postoperative side effects, which facilitates the enhanced recovery after thoracoscopic lung surgery.

Objective:To observe the clinical efficacy of immediate repair of extracranial branch defects in the facial nerve through transplantation of the great auricular nerve.Methods:A retrospective inclusion was carried out on 17 patients with extracranial branch defects of the facial nerve caused by parotid malignant tumors and neurogenic tumors in the Department of Stomatology of Xuzhou Central Hospital from June 2021 to January 2023, including 10 males and 7 females, with the age ranged from 28 to 68 (42.4±11.4) years old. All patients underwent immediate transplantation of the greater auricular nerve during the operation. The facial nerve function was evaluated according to the House-Brackmann (HB) facial paralysis grading standard at the last follow-up. Grade Ⅰ-Ⅲ was considered effective, and grade Ⅳ-Ⅵ was considered ineffective. The quality of life was evaluated using the physical function score (FDIP) and social function score (FDIS).Results:The follow-up time was 6-30 (18.3 ±6.6) months. The facial nerve function was classified as grade Ⅰ in four cases, grade Ⅱ in six cases, grade Ⅲ in four cases, and grade Ⅳ in three cases. This resulted in an effective rate of 14/17. The FDIP score at the final follow-up was (84.7 ±9.1) points, which was higher than the (54.1 ±20.6) points recorded at the immediate moment of repair ( P<0.001). In contrast, the FDIS score was (11.8 ±8.9) points, which was lower than the (57.5 ±11.7) points recorded at the immediate moment of repair ( P<0.001). Conclusion:The transplantation of the auricular great nerve can effectively enhance facial nerve function and improve the life quality in the immediate repair of defects in the extracranial branches of the facial nerve.

An 85-year-old male patient received immunotherapy with toripalimab (240 mg by intravenous infusion on day 1, 21 days as one treatment cycle). After one week of the first medication, the patient experienced fatigue, poor appetite, weight loss, gradually developed mild ptosis of the right eyelid, shortness of breath and palpitations after activity, which were progressively aggravated. The patient also developed unclear speech, choking on water, and difficulty breathing. Laboratory tests showed alanine aminotransferase (ALT) 93 U/L, aspartate aminotransferase (AST) 171 U/L, creatine kinase (CK) 2 982 U/L, creatine kinase isoenzyme (CK-MB) 110 U/L, lactate dehydrogenase (LDH) 603 U/L, and high-sensitivity troponin T (hs-cTnT) 243 ng/L. All indicators of thyroid function were abnormal. Based on results of the laboratory tests, neurophysiological examination, and electrocardiogram examination, combined with the patient′s clinical symptoms, immune-mediated hepatitis of grade 2, immune-mediated myocarditis of grade 3, myasthenia gravis of grade 3, immune-mediated myositis of grade 2, and thyroid dysfunction of grade 1 were diagnosed, which was considered to be induced by toripalimab. Toripalimab was stopped. After treatments with glucocorticoids, liver-protective drugs, and symptomatic treatments, above-mentioned indicators showed a downward trend. After 27 days of treatments, the patient′s clinical symptoms were improved significantly. Laboratory tests showed ALT 123 U/L, AST 68 U/L, CK 116 U/L, CK-MB 42 U/L, LDH 305 U/L. The thyroid function indicators were all normal. After 57 days of treatments, above symptoms in the patient basically disappeared, and laboratory indicators tended to be normal.

Objective:To compare the clinical efficacy of laparoscopic pelvic floor autologous fascia integral repair based on membrane anatomy versus transperineal proctosigmoidectomy (Altemeier procedure) in the treatment of patients with complete rectal prolapse (CRP).Methods:This study employed a retrospective observational cohort design. Clinical data were collected from a total of 55 CRP patients who underwent surgical treatment between January 2018 and July 2023, including 25 patients from Luoyang Central Hospital, affiliated with Zhengzhou University, and 30 patients from the 989th Hospital of the Joint Logistics Support Force & Military Anorectal Surgery Research Institute. All patients undergoing surgery met the following criteria: aged ≥ 18 years, rectal prolapse protruding outside the anus, prolapse length > 5 cm with inability to self-reduce, conforming to the diagnostic criteria for CRP, and being first-time treated patients. Twenty-seven patients who underwent the Altemeier procedure between January 2018 and March 2021 were assigned to the Altemeier group; 28 patients who underwent laparoscopic pelvic floor autologous fascia integral repair based on membrane anatomy between April 2021 and July 2023 were assigned to the integral repair group. The therapeutic efficacy differences between the two groups were analyzed and compared, including the CRP length (DCRP), Wexner Constipation Score, Wexner Fecal Incontinence Score, and Gastrointestinal Quality of Life Index (GIQLI) before surgery and at 6, 12, and 24 months after surgery, as well as postoperative complications and recurrence at 24 months after surgery.Results:There were no statistically significant differences between the two groups in terms of gender distribution, age, preoperative body mass index (BMI), defecation frequency, DCRP, Wexner Constipation Score, Wexner Fecal Incontinence Score, and GIQLI (all P>0.05). All patients completed the surgery. The length of hospital stay and intraoperative blood loss in the integral repair group were significantly less than those in the Altemeier group (both P<0.01). At 6, 12, and 24 months after surgery, the DCRP, Wexner Constipation Score, Wexner Fecal Incontinence Score, and GIQLI in both groups significantly improved compared with the preoperative values (all P<0.001). At 6, 12, and 24 months after surgery, the CRP treatment effect, Wexner Constipation Score, Wexner Fecal Incontinence Score, and GIQLI in the integral repair group were significantly better than those in the Altemeier group (χ2=15.821, P<0.001; χ2=18.238, P<0.001; χ2 = 12.558, P=0.001; and χ2 =22.413, P<0.001, respectively). In the integral repair group, 4 patients (14.3%) developed grade I-III postoperative complications, including 2 cases of urinary retention, 1 case of anastomotic bleeding, and 1 case of anastomotic stenosis. In the Altemeier group, 11 patients (40.7%) developed grade I-III postoperative complications, including 4 cases of urinary retention, 3 cases of anastomotic bleeding, 1 case of anastomotic stenosis, 2 cases of intestinal fistula, and 1 case of fecal incontinence. The difference between the two groups was statistically significant (χ2=4.850, P=0.028). There was no recurrence of CRP in the integral repair group at 24 months after surgery, while 7 cases of CRP recurrence were observed in the Altemeier group at 24 months after surgery. The difference between the two groups was statistically significant (χ2=6.148, P=0.013). Conclusion:The autologous fascia repair technique based on membrane anatomy and the pelvic floor integral theory is superior to the transperineal Altemeier procedure in the treatment of CRP. Furthermore, it is an effective surgical method for CRP.

Objective To systematically evaluate robot-assisted gait training(RAGT)on motor function,ambulation and activities of daily living of patients after stroke and spinal cord injury(SCI),and to investigate the clinical value of differ-ent robotic technologies and control strategies.Methods In accordance with PRISMA guidelines,relevant randomized controlled trials(RCTs)published between 2020 and 2024 were identified from databases including Scopus,Web of Science,PubMed,Cochrane Library and CNKI.The PEDro scale was used to assess methodological quality,and a comprehensive analysis was performed on the therapeutic effects of RAGT on walking ability,balance,lower limb muscle strength and functional inde-pendence.Results Eight RCTs involving 702 participants were included,originating from countries such as China,Italy,India,Tur-key and Poland.The population consisted of adult patients with various subtypes of stroke or SCI.These studies were published in journals across geriatric neuroscience,biosciences,medicine and sports science.Interventions involved three categories of lower limb exoskeleton including treadmill-based systems(end-effector and exoskel-eton models),overground exoskeletons and specialized joint/platform-based robots.The training frequency was 20 to 45 minutes a time,once to twice a day,one to seven days a week,for a total of two to ten weeks.RAGT might significant improve gait parameters and lower limb muscle strength,though its impact on functional inde-pendence was heterogeneous.Adaptive control strategies(e.g.,assist-as-needed)proved superior to fixed-parame-ter modes.Treadmill-based systems(e.g.,Lokomat)were well-suited for early-stage rehabilitation,while over-ground exoskeletons(e.g.,EKSO-GT)better facilitated adaptation to real-world environments.Conclusion RAGT is an effective modality for improving gait and lower limb function of patients with stroke and SCI.The therapeutic outcome is contingent upon personalized setup of the exoskeleton and the implementation of adaptive control strategies.Different adaptive control modes have been developed for the three main types of lower limb exoskeleton.Rehabilitation training should consider the specific lower limb tasks with the robot's cor-responding adaptive movement and control modes.

Diabetic retinopathy（DR）， as one of the most common and serious microvascular complications of diabetes mellitus， seriously threatens human health， and belongs to "Xiaoke eye diseases" in traditional Chinese medicine（TCM）， which has been richly experienced by medical practitioners through the ages， but is mostly recorded in a piecemeal manner and has not been systematically researched. This disease is featured by long course and repeated attack， and is refractory， which belongs to the research category of "persistent illness entering collaterals". Systematic establishment of TCM collateral disease theory for guiding prevention and treatment of DR has important clinical value. On the basis of close correlation between tertiary collaterals at the terminal of collaterals and capillaries and microcirculation， the concept of "tertiary collaterals-microvascular" is proposed. It is pointed out that DR falls within the scope of "tertiary collaterals-microvascular" diseases， and presents four types of micro-pathological characteristics， including stasis， insufficiency， growth and bleeding of tertiary collaterals. It is concluded that "deficiency of both Qi and Yin" is the basic pathogenesis of DR， and "blood stasis and collateral obstruction" is the important pathogenesis and key factor. Thus， the treatment method of "dispersing blood stasis， dredging collateral， tonifying Qi and Yin， stopping hemorrhage and improving eyesight" is determined， and the formula of Tongluo Mingmu capsules is developed. The article tightly focuses on the pathological changes such as stasis， growth， insufficiency and bleeding of collaterals， addresses both symptoms and root causes， and plays a synergistic role of both dispersing stasis and stopping bleeding. In this way， it can realize the purpose of tonifying Qi and Yin to replenish the essence， dispersing stasis and dredging collaterals to meet the requirement， as well as stopping hemorrhage and improving eyesight to deal with changes. Fundamental researches demonstrate that Tongluo Mingmu capsules has synergy effects of protecting both retinal capillaries and retinal cells. Phase-Ⅲ clinical trial of new drug has proven definite clinical efficacy and good safety， which provides a new drug choice for enhancing clinical effect of DR， and further supports the scientific value of Luobing theory in preventing and treating DR and other clinically significant diseases.

The theoretical basis of premature aging originates from The Yellow Emperor's Inner Classic. The etiology of premature aging is complex， and the disease mechanism is based on deficiency. The treatment for premature aging is based on tonicity. The essence-Qi-spirit theory of Qiluo doctrine summarizes that "essence is the origin of life， Qi is the driving force of life， and spirit is the embodiment of life"， which is the law of life. The theory puts forward the core disease mechanism of aging， which states that "deficiency of kidney essence is the root of aging， deficiency of primordial Qi is the key to aging， impairment of soma and spirit is the manifestation of aging". The theory also proposes the treatment of "tonifying kidney and supplementing essence， harmonizing Yin and Yang， warming and supporting primordial Qi， and nourishing soma and spirit" and the representative anti-aging drugs. The article unfolds from the perspective of the concepts of natural life span， premature senility before fifty， decline， and aging and also explains the origins and connotations of premature aging. The article explains the disease mechanism of premature aging under the guidance of the essence-Qi-spirit theory of Qiluo doctrine， which is "early deprivation of kidney essence， deficiency of primordial Qi， accumulation of deficiencies into impairment， and decline and impairment of soma and spirit"， summarizes the progress of modern medical research on the treatment of premature aging and representative drugs， and finds that Bazi Bushen capsules have a precise therapeutic effect on the overall premature aging， systematic functional decline， and related diseases. The study provides theoretical basis and new ideas to solve the problems of premature aging and geriatric diseases.

PURPOSE: We carried out the study aiming to explore and analyze the risk factors, the distribution of pathogenic bacteria, and their antibiotic-resistance characteristics influencing the occurrence of surgical site infection (SSI), to provide valuable assistance for reducing the incidence of SSI after traumatic fracture surgery. METHODS: A retrospective case-control study enrolling 3978 participants from January 2015 to December 2019 receiving surgical treatment for traumatic fractures was conducted at Tangdu Hospital of Air Force Medical University. Baseline data, demographic characteristics, lifestyles, variables related to surgical treatment, and pathogen culture were harvested and analyzed. Univariate analyses and multivariate logistic regression analyses were used to reveal the independent risk factors of SSI. A bacterial distribution histogram and drug-sensitive heat map were drawn to describe the pathogenic characteristics. RESULTS: Included 3978 patients 138 of them developed SSI with an incidence rate of 3.47% postoperatively. By logistic regression analysis, we found that variables such as gender (males) (odds ratio (OR) = 2.012, 95% confidence interval (CI): 1.235 - 3.278, p = 0.005), diabetes mellitus (OR = 5.848, 95% CI: 3.513 - 9.736, p < 0.001), hypoproteinemia (OR = 3.400, 95% CI: 1.280 - 9.031, p = 0.014), underlying disease (OR = 5.398, 95% CI: 2.343 - 12.438, p < 0.001), hormonotherapy (OR = 11.718, 95% CI: 6.269 - 21.903, p < 0.001), open fracture (OR = 29.377, 95% CI: 9.944 - 86.784, p < 0.001), and intraoperative transfusion (OR = 2.664, 95% CI: 1.572 - 4.515, p < 0.001) were independent risk factors for SSI, while, aged over 59 years (OR = 0.132, 95% CI: 0.059 - 0.296, p < 0.001), prophylactic antibiotics use (OR = 0.082, 95% CI: 0.042 - 0.164, p < 0.001) and vacuum sealing drainage use (OR = 0.036, 95% CI: 0.010 - 0.129, p < 0.001) were protective factors. Pathogens results showed that 301 strains of 38 species of bacteria were harvested, among which 178 (59.1%) strains were Gram-positive bacteria, and 123 (40.9%) strains were Gram-negative bacteria. Staphylococcus aureus (108, 60.7%) and Enterobacter cloacae (38, 30.9%) accounted for the largest proportion. The susceptibility of Gram-positive bacteria to Vancomycin and Linezolid was almost 100%. The susceptibility of Gram-negative bacteria to Imipenem, Amikacin, and Meropenem exceeded 73%. CONCLUSION Orthopedic surgeons need to develop appropriate surgical plans based on the risk factors and protective factors associated with postoperative SSI to reduce its occurrence. Meanwhile, it is recommended to strengthen blood glucose control in the early stage of admission and for surgeons to be cautious and scientific when choosing antibiotic therapy in clinical practice.

Objective To analyze clinical characteristics affecting survival outcomes in gastric adenocarcinoma(GAC)patients with second primary malignancies(SPM)and construct a predictive model with a web-based calculator.Methods Patients diagnosed with GAC between January 2010 and December 2017 in the SEER database(n=24 085)were analyzed,comparing non-SPM(n=22 963)and SPM cohorts(n=1 122).SPM patients were randomized(3:1)into training(n=842)and internal validation cohorts(n=280).Univariate/multivariate Cox regression identified prognostic factors for model construction.Model performance was evaluated via ROC curves,calibration plots,and decision curve analysis(DCA).A web-based calculator was deployed using DynNom(https://kunma697.shinyapps.io/dynnomapp-1/).External validation used 192 SPM patients diagnosed at Yantai Yuhuangding Hospital(2010-2017).Results χ2 tests revealed SPM patients had higher age(56.3%),earlier T-stage(T1:29.2%;T2:10.5%),predominant gastric cardia involvement(43.7%),fewer distant metastases(12.3%),and higher rates of radiotherapy(32.5%)and surgery(77.2%)vs.non-SPM(P<0.05).Cox analyses identified GAC primary site,T-stage,SEER stage,radiotherapy/surgery history,plus SPM grade/stage/treatment history as significant predictors(P<0.05).AUCs in the training cohort were 0.771(95%CI:0.722～0.820),0.839(95%CI:0.796～0.882),and 0.836(95%CI:0.792～0.879)for 1-/3-/5-year survival;internal validation showed 0.751(95%CI:0.700～0.801),0.746(95%CI:0.695～0.797),and 0.772(95%CI:0.723～0.821);external validation yielded 0.713(95%CI:0.648～0.778),0.805(95%CI:0.749～0.861),and 0.851(95%CI:0.801～0.901).Calibration indicated high prediction-actuality concordance;DCA confirmed clinical utility.Conclusion The model and web calculator incorporating GAC/SPM characteristics effectively predict SPM patient prognosis.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.
