Objective·To evaluate the effects of anterior maxillary segmental distraction osteogenesis(AMSDO)in treating sagittal maxillary hypoplasia in cleft lip and palate(CLP)patients and to report a 3D-printed surgical guide to facilitate the osteotomy.Methods·Twelve patients with CLP who underwent AMSDO were included in this study.Virtual osteotomy was performed in a 3-dimensional model and the osteotomy line were fabricated into a tooth-borne surgical guide by using 3D-printing technique.Lateral cephalograms taken before surgery(T0),at the end of consolidation(T1)and six months after consolidation(T2)were used to evaluate the effects of AMSDO.The accuracy of the osteotomy guide was measured by superimposing the postoperative CT data to virtual planning.Results·All the patients went through surgery without serious complications.SNA and overjet changed significantly both from T0 to T1 and from T0 to T2.ANB,facial convexity,and palatal length changed without significance from T0 to T1 and from T0 to T2.SNB remained stable.All the variables remained relatively stable from T1 to T2.The anteroposterior linear root-mean-square deviation(RMSD)between planning and actual results was 0.90 mm,while the angular RMSD in the sagittal plane was 5.07°.Conclusion·AMSDO is an effective treatment for maxillary hypoplasia secondary to CLP.The accuracy of this 3D-printed osteotomy guide is clinically acceptable,and this can simplify the surgery with fewer complications.

Objective:To observe any effect of cooling on the amplitude of vibration-induced sensory nerve action potentials (SNAPs) in human digits.Methods:The middle fingers of 15 healthy adults were either cooled to about 22℃ using an ice pack or kept at about 32℃. A vibrator was applied to the joint connecting the middle finger and the palm vibrating with an amplitude of 2mm at a frequency of 60Hz. The amplitudes of middle finger SNAPs before, during and right after the vibration were recorded.Results:The SNAP amplitude at a given temperature was lower during vibration than before it, but it immediately returned to the pre-vibration level after the vibration ceased. The middle finger SNAP amplitudes at 22℃ were significantly higher than those at 32℃ throughout. The decrease in amplitude at 32℃ (61.7±15.1%) was significantly greater than that at 22℃ (24.1±7.0%).Conclusions:Cooling significantly reduces the effect of vibration on the amplitude of digital SNAPs. That suggests a way to protect the sensory nerves in hand-arm vibration syndrome.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective:To investigate the feasibility and potential of fluorescent cholecystic bile duct visualization with direct intravenous injection of indocyanine green(ICG) in obese patients undergoing laparoscopic cholecystectomy(LC).Methods:The clinical data of 132 patients with LC combined with obesity admitted to the Department of Hepatobiliary and Pancreatic Surgery of the Second People′s Hospital of Changzhou City, affiliated to Nanjing Medical University, from January 2023 to July 2023 were retrospectively analyzed. They were divided into fluorescence group( n=65) and control group( n=67) according to whether indocyanine green fluorescence navigation was used or not. There were 50 males and 82 females, and all the enrolled patients body mass index≥28 kg/m 2. Two groups identify the time of the three tubes, intraoperative bleeding, operation time, postoperative hospitalization time, white blood cell count(WBC), C-reactive protein(CRP), alanine aminotransferase(ALT), gamma-glutamyl transferase(GGT), and postoperative follow-up in the fluorescent and control groups were counted respectively. Measurement data with skewed distribution were expressed as M( Q1, Q3), and intergroup comparisons were performed using the Mann-Whitney U test; counting data were described by frequency(rate), and intergroup comparisons were made by applying the chi-square test, Fisher′s exact probability method, and chi-square corrected test according to the difference in the minimum frequency. Results:Surgery was successfully completed in both groups. Preoperative inflammatory indicators and liver function levels were also not statistically significant( P>0.05). The time to identify the three tubes, operation time, intraoperative bleeding, and postoperative hospitalization in the fluorescence group were 18.00(13.50, 20.00) min, 40.00(30.00, 50.00) min, 5.00(5.00, 10.00) mL, and 2.00(1.50, 3.00) d, and in the control group were 32.00(25.00, 45.00) min, 65.00(50.00, 85.00) min, 41.00(41.00, 46.00) mL, and 4.00(3.00, 5.00) d. The differences between the two groups were statistically significant( P<0.05). The postoperative leukocyte count, postoperative CRP, and postoperative GGT were 9.15(7.10, 11.75)×10 9/L, 7.19(3.22, 20.00) mg/L, and 34.0(20.0, 49.0) U/L in the fluorescence group, and 13.05(11.02, 15.59)×10 9/L, and 18.78(12.90, 32.95) mg/L in the control group, respectively, 82.5(68.5, 114.5) U/L, and the differences between the two groups were statistically significant ( P<0.05). None of the patients showed abdominal pain, abnormal liver function and hepatobiliary ultrasound in the follow-up findings within 2 months after surgery. Conclusion:The effect of obesity, a factor that interferes with ICG fluorescence, is extremely limited, and ICG fluorescence cholangiography is a useful technique in the obese population that not only improves the efficiency of the procedure, but also increases intraoperative safety, with results superior to those of conventional laparoscopic cholecystectomy.

AIM:To explore the effect of microRNA-184(miR-184)on compensatory lung growth(CLG)af-ter lobectomy in multiple primary lung cancer(MPLC)and its mechanism.METHODS:(1)Lung tissue samples(n= 16)from MPLC patients and patients with good recovery after lobectomy(CLG)were collected,and the expression of miR-184 was measured by RT-qPCR.(2)Human alveolar epithelial cells were divided into NC-mimic group,miR-184 mimic group,OE-NC group,tissue inhibitor of metalloproteinase-2(TIMP-2)overexpression(OE-TIMP-2)group,and miR-184 mimic+OE-TIMP-2 group according to the transfection(n=3).The expression of miR-184,TIMP-2 mRNA and matrix metalloproteinase-14(MMP-14)mRNA was measured by RT-qPCR,and the protein expression of TIMP-2 and MMP-14 was determined by Western blot.The proliferation of the cells was measured by CCK-8 and colony formation assays.(3)C57BL/6J mice were divided into pneumonectomy(PNX)group and PNX+miR-184 mimic group(n=5).The flexiVent system was used to measure the vital capacity and lung compliance of the mice.Lung volume was measured by water dis-placement method,and lung tissue changes were observed by HE staining.RESULTS:The expression of miR-184 was significantly higher in the patients with better recovery after lobectomy(P＜0.01).Overexpression of miR-184 promoted the proliferation of human alveolar epithelial cells and the recovery of lung function in mice after PNX.In terms of mecha-nism,miR-184 showed targeted binding with TIMP-2,and overexpression of miR-184 promoted the expression of MMP-14 by inhibiting TIMP-2,thereby promoting the proliferation of human alveolar epithelial cells and the recovery of mouse lung function after PNX.CONCLUSION:miR-184 promotes CLG after PNX through the TIMP-2/MMP-14 axis.

This study aimed to explore key quality control factors that affected the prognosis of intensive care unit (ICU) patients in Chinese mainland over six years (2015-2020). The data for this study were from 31 provincial and municipal hospitals (3425 hospital ICUs) and included 2 110 685 ICU patients, for a total of 27 607 376 ICU hospitalization days. We found that 15 initially established quality control indicators were good predictors of patient prognosis, including percentage of ICU patients out of all inpatients (%), percentage of ICU bed occupancy of total inpatient bed occupancy (%), percentage of all ICU inpatients with an APACHE II score ⩾15 (%), three-hour (surviving sepsis campaign) SSC bundle compliance (%), six-hour SSC bundle compliance (%), rate of microbe detection before antibiotics (%), percentage of drug deep venous thrombosis (DVT) prophylaxis (%), percentage of unplanned endotracheal extubations (%), percentage of patients reintubated within 48 hours (%), unplanned transfers to the ICU (%), 48-h ICU readmission rate (%), ventilator associated pneumonia (VAP) (per 1000 ventilator days), catheter related blood stream infection (CRBSI) (per 1000 catheter days), catheter-associated urinary tract infections (CAUTI) (per 1000 catheter days), in-hospital mortality (%). When exploratory factor analysis was applied, the 15 indicators were divided into 6 core elements that varied in weight regarding quality evaluation: nosocomial infection management (21.35%), compliance with the Surviving Sepsis Campaign guidelines (17.97%), ICU resources (17.46%), airway management (15.53%), prevention of deep-vein thrombosis (14.07%), and severity of patient condition (13.61%). Based on the different weights of the core elements associated with the 15 indicators, we developed an integrated quality scoring system defined as F score=21.35%xnosocomial infection management + 17.97%xcompliance with SSC guidelines + 17.46%×ICU resources + 15.53%×airway management + 14.07%×DVT prevention + 13.61%×severity of patient condition. This evidence-based quality scoring system will help in assessing the key elements of quality management and establish a foundation for further optimization of the quality control indicator system.

Objective:To investigate the correlation between serum uric acid to albumin ratio (UAR) and large-artery atherosclerosis (LAA), its severity and short-term outcome.Methods:Patients with acute ischemic stroke admitted to the Department of Neurology, the Affiliated Hospital of Qingdao University from September 2017 to August 2022 were retrospectively enrolled. They were classified into LAA and non-LAA according to the TOAST etiological criteria. Patients with LAA were further divided into mild stroke group (≤8) and moderate to severe stroke group (>8) according to the National Institutes of Health Stroke Scale score at admission, and good outcome group (≤2) and poor outcome group (>2) according to the modified Rankin Scale score at discharge. Multivariate logistic regression analysis was used to determine the correlation between UAR and LAA, its severity and short-term outcome. The predictive value of UAR for poor outcomes in patients with LAA was evaluated by receiver operating characteristic (ROC) curve. Results:A total of 4 178 patients with acute ischemic stroke were enrolled, including 2 751 males (65.8%), aged 61.95±10.73 years. There were 2 000 (47.9%) patients with LAA, including 1 112 (55.6%) mild stroke and 888 (44.4%) moderate to severe stroke; 813 (40.65%) had good short-term outcomes and 1 187 (59.35%) had poor outcomes. UAR in the LAA group was significantly higher than that in the non-LAA group ( P<0.05). In patients with LAA, the UAR of the moderate to severe stroke group and the short-term poor outcome group were significantly higher than that of the mild stroke group and the short-term good outcome group, respectively (all P<0.05). Multivariate logistic regression analysis showed that the UAR was an independent risk factor for LAA (odds ratio [ OR] 1.043, 95% confidence interval [ CI] 1.016-1.071; P=0.002), its severity ( OR 2.000, 95% CI 1.860-2.151; P<0.001), and short-term poor outcomes ( OR 1.456, 95% CI 1.379-1.537; P<0.001). ROC curve analysis showed that the area under the curve of UAR for predicting short-term poor outcomes in patients with LAA was 0.727 (95% CI 0.704-0.750; P<0.001). The optimal cutoff value was 6.62, and the sensitivity and specificity were 86.6% and 56.7%, respectively. The area under the curve of UAR for predicting short-term poor outcomes in patients with LAA was greater than that predicted solely by uric acid and albumin. Conclusions:UAR is associated with LAA, its severity and poor prognosis, and has higher predictive value for poor outcomes in patients with LAA.

The prevalence of osteoporosis， osteoarthritis， gouty arthritis， rheumatoid arthritis， and intervertebral disc degeneration is increasing year by year with the growing number of elderly people， and the common clinical manifestations of these diseases include severe pain in different areas， which seriously affects the daily life of the patients. Therefore， how to relieve the pain and reduce the prevalence of bone and joint diseases and improve the quality of life of the patients is a hot spot in the medical field. Studies have confirmed that NOD-like receptor family， pyrin domain-containing protein 3 （NLRP3） inflammasomes， as pattern recognition receptors， are involved in the inflammation， chondrocyte proliferation， osteoblast and osteoclast differentiation， intervertebral disc cell inflammation and scorching， extracellular matrix degradation and apoptosis， mitochondrial dysfunction， endoplasmic reticulum stress， and reactive oxygen species damage， demonstrating close link with the development of bone and joint diseases. Chinese medicine has a long history and demonstrates remarkable therapeutic effects in the treatment of bone and joint diseases. It can mitigate the pathological changes of bone and joint diseases by inhibiting NLRP3 inflammasomes to alleviate the pain， playing a role in preventing and treating these diseases. Therefore， this paper briefly describes the relationship between NLRP3 inflammasomes and the development of bone and joint diseases by reviewing the latest research progress at home and abroad. We summarize the latest studies about the active components， extracts， and compound prescriptions of Chinese medicines in the treatment of bone and joint diseases via regulating NLRP3 inflammasomes. This review is expected to offer new insights into the in-depth research on the pathogenesis and drug treatment of bone and joint diseases and provide a basis for the clinical application of Chinese medicine in the prevention and treatment of such diseases.
