OBJECTIVE:Anterior cervical decompression and fusion is a classic surgical method for the treatment of degenerative cervical spondylosis.The use of nail plates increases the fusion rate and stability and indirectly leads to adjacent vertebral degeneration and postoperative dysphagia.In this paper,the clinical results and complications of ROI-CTM self-locking system and traditional cage combined with screw-plate internal fixation in the treatment of degenerative cervical spondylosis were compared by meta-analysis to provide evidence-based support for the selection of internal fixation methods in anterior cervical decompression and fusion. METHODS:CNKI,WanFang,VIP,PubMed,Cochrane Library,Web of Science,and Embase databases were searched for Chinese and English literature on the application of ROI-CTM self-locking system and fusion cage combined with screw plate internal fixation in the treatment of degenerative cervical spondylosis.The retrieval time range was from inception to July 2023.Two researchers selected the literature strictly according to the inclusion and exclusion criteria.The Cochrane bias risk tool was used to evaluate the quality of randomized controlled trials.Newcastle-Ottawa Scale was used to assess the quality of cohort studies.Meta-analysis was performed using RevMan 5.4 software.Outcome indicators included operation time,intraoperative blood loss,Japanese Orthopaedic Association score,Neck Disability Index,C2-C7 Cobb angle,fusion rate,incidence of adjacent vertebral degeneration,cage subsidence rate,and incidence of dysphagia. RESULTS:Thirteen articles were included,including eleven retrospective cohort studies and two randomized controlled trials,with 1 136 patients,569 in the ROI-C group,and 567 in the cage combined with the nail plate group.Meta-analysis results showed that the operation time(MD=-15.52,95%CI:-18.62 to-12.42,P<0.000 01)and intraoperative blood loss(MD=-24.53,95%CI:-32.46 to-16.61,P<0.000 01)in the ROI-C group and the fusion device combined with nail plate group.Postoperative adjacent segment degeneration rate(RR=0.40,95%CI:0.27-0.60,P<0.000 01)and postoperative total dysphagia rate(RR=0.18,95%CI:0.13-0.26),P<0.000 01)were statistically different.The two groups had no significant difference in Japanese Orthopaedic Association score,Neck Disability Index,C2-C7 Cobb angle,fusion rate,or cage subsidence rate(P≥0.05). CONCLUSION:Applying an ROI-CTM self-locking system and traditional cage combined with plate internal fixation in anterior cervical decompression and fusion can achieve satisfactory clinical results in treating degenerative cervical spondylosis.The operation of the ROI-CTM self-locking system is more straightforward.Compared with a cage combined with plate internal fixation,the ROI-CTM self-locking system can significantly reduce the operation time and intraoperative blood loss and has obvious advantages in reducing the incidence of postoperative dysphagia and adjacent segment degeneration.The ROI-CTM self-locking system is recommended for patients with skip cervical spondylosis and adjacent vertebral disease.However,given its possible high settlement rate,using a fusion cage combined with screw-plate internal fixation is still recommended for patients with degenerative cervical spondylosis with multiple segments and high-risk factors of fusion cage settlement,such as osteoporosis and vertebral endplate damage.

Objective To evaluate the applicability of a modified U-shaped forearm flap for the repair of small-and medium-sized defects in the oral and maxillary areas to provide a reference for clinicians.Methods This study was re-viewed and approved by the Ethics Committee,and informed consent was obtained from the patients.Ten patients with small-and medium-sized defects in the oral and maxillary areas underwent surgical repair using modified U-shaped fore-arm flaps.There were 8 males and 2 females aged 43-72 years.The donor site was apposed primarily after harvesting the modified U-shaped forearm skin flap.The flaps ranged from 6 cm × 4 cm to 8 cm × 5 cm in size.Six months after the operation,hand movements(finger extension,fist clenching,wrist rotation upward and wrist rotation downward),the forearm donor site,hand sensations and the satisfaction score for the postoperative quality of the scar at the donor site were evaluated(0 to 10;0:very unattractive,10:very satisfactory).Results A total of 10 patients with modified U-shaped forearm flaps survived.One patient developed venous crisis 24 hours after surgery and survived after surgical ex-ploration.Delayed healing occurred at the donor site of the forearm in 1 patient,and the wounds at the donor site of the forearm in the other patients all healed in the first stage.One patient presented with dysesthesia in the hand 2 weeks af-ter surgery and recovered within 3 months.Six months after surgery,all patients had no limited hand movement and no paresthesia at the forearm donor site or hand.The patients were basically satisfied with the appearance of the donor site,and the average satisfaction score of the subjective questionnaire was 8.4 points.Conclusion Modified U-shaped fore-arm flaps can directly close forearm donor site wounds,which avoids surgical trauma to the secondary donor site and sig-nificantly reduces related complications.Modified U-shaped forearm flaps provide an alternative to conventional forearm flaps for the repair of small-and medium-sized defects in the oral and maxillary areas.

Objective To investigate the risk factors for pediatric acute perforation appendicitis,and to construct a nomogram predictive model and conduct the verification.Methods A total of 426 children patients with appendectomy in this hospital from June 30,2020 to June 30,2022 were selected as the study subjects 340 children with acute appendicitis admitted to the hospital from 30 June 2020 to 28 February 2022 were the training set and 86 children patients with appendicitis hospitalized in this hospital from March 1,2022 to June 30,2022 conducted the external validation(verification set).The univariate and multivariate logistic regression models were employed to analyze the independent risk factors of pediatric acute perforation appendicitis.The nomograms predictive model was constructed.The receiver operating characteristic(ROC)curve and calibra-tion curve were used to evaluate the predictive efficiency of the model.The decision curve analysis(DCA)was used to evaluate the application value of the model.Results Of the 426 children,198 were perforated and 228 were not perforated.The univariate and multivariate logistic regression analyses revealed that elevated C-reac-tive protein(CRP),presence of stercorolith in appendiceal cavity,time of onset to visiting hospital ≥2 d and body temperature ≥37.3 ℃ were the independent risk factors for pediatric acute perforation appendicitis(P＜0.05).The Hosmer-Lemeshow test demonstrated that the nomogram predictive model had good fitting(P=0.869),and the area under the curve(AUC)for the training and validation sets were 0.808 and 0.860 respectively,showing the good predictive ability of the model.The calibration curve closely approach the ideal diagonal.The model showed good discrimination,consistency and accuracy.The DC A revealed that the curve was far away from oblique and horizontal lines,and the model had good clinical practicability.Conclusion The constructed nomogram model of pediatric acute perforation appendicitis has good predictive ability and may help clinic to identify as early as possible.

Objective To construct and validate of a nomogram predictive model for high-volume lymph node metastasis(HVM)in multifocal papillary thyroid carcinoma(MPTC).Methods Between January 2010 to January 2024,a total of 1146 and 234 patients with multifocal papillary thyroid carcinoma(MPTC)were diagnosed at Hangzhou First People's Hospital(Center A)and Hangzhou Cancer Hospital(Center B),respectively.Patients from Center A were randomly allocated to training set(n=803)and testing set(n=343)in a 7:3 ratio,while those from Center B(n=234)comprised an external validation set.Independent risk factors for HVM in MPTC patients were identified through univariate and multivariate Logistic regression analysis in training set,leading to the development of a nomogram predictive model.The generalizability of this model was subsequently assessed using both testing set and external validation set.The area under the curve(AUC)of receiver operating characteristic curve,sensitivity,and specificity evaluate the discriminative ability of the model.Results The incidence of HVM was 13.3％at center A and 12.8％at center B.Logistic regression identified male gender(OR=2.91,95％CI:1.835-4.599),maximum lesion diameter(OR=1.05,95％CI:1.021-1.070),and age(OR=0.95,95％CI:0.936-0.972)as independent risk factors for HVM.Anomogram based on these factors showed an AUC of 0.767 with 72.6％sensitivity and 70.2％specificity in training set,and 0.838 with 94.9％sensitivity and 68.4％specificity in testing set,and 0.769 with 63.3％sensitivity and 84.3％specificity in external validation set.The calibration curve demonstrated good agreement with the ideal curve.Conclusion The prediction model constructed based on clinical risk factors can effectively predict the probability of HVM in MPTC patients.

Objective:To analyze assessment value of the hemodynamics of posterior cerebral artery(PCA)detected by transcranial color-coded Doppler(TCCD)ultrasound for occurring cerebral infarction in patients with fetal-type posterior cerebral artery(FTP).Methods:A total of 300 patients with suspected cerebrovascular disease admitted to the Department of Neurology of The Second Hospital of Harbin City from January,2020 to December 31,2023 were retrospectively selected.In these patients,7 cases with cerebral hemorrhage(without complication of cerebral infarction)did not be included.According to the clinical manifestations and the results of imaging examination,293 patients were divided into transient ischemic attack(TIA)group(176 cases)and acute ischemic stroke(AIS)group(117 cases).The differences in FTP detection between TCCD examination and magnetic resonance angiography(MRA)were compared.The differences in PCA hemodynamics among TIA,anterior circulation infarction,posterior circulation infarction and lacunar infarction were compared.The proportions of patients with TIA,anterior circulation infarction,posterior circulation infarction and lacunar infarction combined with FTP were also compared,and the PCA hemodynamics of patients with posterior circulation infarction of bilateral cFTP,unilateral cFTP,bilateral pFTP,unilateral pFTP and nFTP were compared.The proportions of patients with transient ischemic attack(TIA)who occurring AIS at bilateral cFTP,unilateral cFTP,bilateral pFTP,unilateral pFTP and nFTP in short term were compared.The receiver operating characteristic(ROC)curve and area under curve(AUC)were used to assess the predictive value of abnormal PCA hemodynamics of TIA patients,who combined with and/or without FTP,occurred AIS in short term.Results:MRA revealed that a total of 89 patients combined with FTP in 293 patients,of which 14 cases were bilateral cFTP(accounting for 15.73%),and 25 cases were unilateral cFTP(accounting for 28.09%),and 8 cases were bilateral pFTP(accounting for 8.99%),and 42 cases were unilateral pFTP(accounting for 4 7.19%).According to TCCD testing,it was found that a total of 89 cases combined with FTP in 293 patients,of which 16 cases were bilateral cFTP(accounting for 17.98%),and 23 cases were unilateral cFTP(accounting for 25.84%),and 8 cases were bilateral pFTP(accounting for 8.99%),and 42 cases were unilateral pFTP(accounting for 47.19%).There was favorable consistency between TCCD and MRA(Kappa=0.899).Under TCCD,the blood flow velocity(Vp)and resistance index(RI)of systolic stage of PCA in patients with posterior circulation infarction were significantly higher than those in patients with TIA,anterior circulation infarction,and lacunar cerebral infarction(F=15.392,9.032,P<0.05),respectively.Patients with posterior circulation infarction were more likely to occur bilateral cFTP.The Vp,Vm and Vd of patients with bilateral cFTP were significantly higher than those of patients with bilateral pFTP,unilateral pFTP and non-FTP(F=14.932,8.884,6.054,P<0.05),respectively.The proportion of occurring AIS in TIA patients with bilateral cFTP was significantly higher than that in TIA patients with unilateral cFTP,bilateral pFTP,unilateral pFTP and nFTP(Z=6.883,7.568,6.253,6.772,P<0.05),and the proportions of occurring AIS in TIA patients with unilateral cFTP,bilateral pFTP and unilateral pFTP were significantly higher than that in TIA patients with nFTP(Z=5.986,6.877,6.856,P<0.05),respectively.A total of 45 cases(accounting for 25.57%)of 176 TIA patients occurred AAIS within 3 months after they discharged.The AUC value of predictive value of Vp for occurring AIS in 45 TIA patients with FTP was 0.818,which was significantly higher than that(AUC=0.589)for occurring AIS in 131 TIA patients with non-FTP.Conclusion:Patients with posterior circulation cerebral infarction are prone to occur PCA hemodynamic abnormalities.In patients with posterior circulation infarction,the PCA blood flow velocity in patients with bilateral cFTP significantly accelerates.PCA hemodynamic ultrasound examination has a certain of predictive value for occurring AIS in short term in TIA patients who combine with FTP.

Objective:To explore the correlation between transcranial sonography (TCS) combined with serum homocysteine (Hcy), blood glucose, blood lipids, the cognitive status of Parkinson′s disease (PD) patients, and to analyze the clinical application value of these parameters in assessing the cognitive status of PD patients.Methods:A total of 152 PD patients admitted to the Second Affiliated Hospital of Soochow University from January 2020 to June 2023 were retrospectively collected as the PD group, and 101 healthy examinees matched for age and gender during the same period were selected as control group. Clinical data [age, gender, duration of illness, Montreal Cognitive Assessment (MoCA) score, Mini-Mental State Examination (MMSE) score, Unified Parkinson′s Disease Rating Scale Part Ⅲ (UPDRS-Ⅲ) score, Hoehn-Yahr (H-Y) stage, etc.], serum tests (Hcy, blood glucose, total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein concentration), and TCS examination results (third ventricular width, midbrain area, peak systolic velocity of bilateral middle cerebral arteries, bilateral middle cerebral artery resistance index, bilateral substantia nigra hyperechoic area) were collected. The two groups were divided into pure PD group and PD group with elevated Hcy, pure control group and control group with elevated Hcy, based on an Hcy concentration threshold of ≥15 μmol/L. The differences in the above parameters among the four groups were compared. The correlation between Hcy and cognitive status (MoCA score, MMSE score) of PD patients and the above parameters were analyzed.Results:The MoCA score and MMSE score of the PD group with elevated Hcy were lower than those of the pure PD group, and the UPDRS-Ⅲ score and H-Y stage were higher than those of the pure PD group (all P<0.001). The order of Hcy concentration from high to low was PD group with elevated Hcy, pure Hcy elevation group, pure PD group, and pure control group. The differences in serum data and TCS data among the four groups were statistically significant (all P<0.001). Spearman correlation analysis showed: ①In the PD group, the concentration of Hcy was positively correlated with glucose concentration, H-Y stage, low-density lipoprotein concentration, right middle cerebral artery resistance index, UPDRS-Ⅲ score, total cholesterol concentration, triglyceride concentration, left middle cerebral artery resistance index, third ventricular width, and age ( rs=0.422, 0.350, 0.348, 0.334, 0.325, 0.300, 0.293, 0.283, 0.221, 0.164, all P<0.05); Hcy concentration was negatively correlated with midbrain area, MMSE score, MoCA score, peak systolic velocity of right middle cerebral artery, peak systolic velocity of left middle cerebral artery, and high-density lipoprotein concentration ( rs=-0.328, -0.282, -0.245, -0.229, -0.224, -0.192, all P<0.05). ②Clinical data, serum data, and TCS data of PD patients were all correlated with MoCA score and MMSE score, with midbrain area showing the largest positive correlation ( rs=0.524, 0.516; both P<0.05) and H-Y stage showing the largest negative correlation( rs=-0.490, -0.468; both P<0.05). Conclusions:PD patients with elevated Hcy have lower cognitive scores than pure PD patients. The correlation between Hcy concentration and blood glucose concentration is the highest in PD patients, followed by H-Y stage. The cognitive scores of PD patients are most correlated with midbrain area and unrelated to substantia nigra hyperechoic area. Lowering serum Hcy concentration in PD patients may be one of the ways to delay cognitive impairment.

Objective:To translate the English version of the Beliefs Toward Mental Illness Scale (BTMI) into Chinese and test the reliability and validity of the Chinese version in college students.Methods:According to the Beaton cross-cultural adaptation guideline, the Chinese version of BTMI was formed. From April to May 2023, a questionnaire survey was conducted on 915 university students from 171 universities in 26 provinces, autonomous regions, and municipalities across China using convenience sampling, to analyze the reliability and validity of the scale.Results:A total of 915 questionnaires were distributed, and 814 valid questionnaires were collected, with an effective recovery rate of 88.96% (814/915). The Chinese version of BTMI had a total of 21 items. The Cronbach's α coefficient of the total scale was 0.922, and the Cronbach's α coefficients of each dimension were 0.745 to 0.921. The half reliability coefficient of the total scale was 0.797, and the retest reliability coefficient of the total scale was 0.903 ( P<0.01). Exploratory factor analysis extracted four common factors, namely social function, risk, incurability, and awkwardness, with a cumulative variance contribution rate of 62.29%. Confirmatory factor analysis showed that all important fitting indicators were greater than 0.900, indicating a good overall model fit. Conclusions:The Chinese version of BTMI has good reliability and validity, which can be used to evaluate the beliefs of Chinese university students about mental illness.

Objective To investigate the effect of green laser anatomical vaporization on patients with benign prostatic hyperplasia(BPH)and type 2 diabetes mellitus(T2DM),as well as its impact on inflammatory factors,quality of life,and urethral stricture.Methods A total of 120 patients with BPH and T2DM who were treated at the First Affiliated Hospital of Xinxiang Medical University from March 2021 to August 2022 were selected as the research subjects.The patients were divided into a control group and an observation group according to the surgical approach,with 60 cases in each group.Patients in the control group underwent green laser selective photovaporization,while patients in the observation group were treated with green laser anatomical vaporization.The intraoperative and postoperative recovery indicators such as operation time,intraoperative blood loss,prostate resection quality,catheter indwelling time,bladder irrigation time,and hospitalization time of patients between the two groups were compared.The serum levels of interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)were detected by using enzyme-linked immunosorbent assay,and the serum levels of malondialdehyde(MDA)and lipid peroxide(LPO)were detected by using immunofluorescence assay before surgery,3 days after surgery,and 7 days after surgery.The international prostate symptom score(IPSS)was used to assess prostate symptoms,the urinary symptom distress score(USDS)was used to assess urinary symptoms,the dynamic urodynamic monitor was used to measure urodynamics[maximum flow rate(Qmax),residual urine volume(RUV)],the enzyme-linked immunosorbent assay was used to detect the serum level of total prostate specific antigen(tPSA),the international index of erectile function-5(IIEF-5)was used to assess erectile function,and the BPH quality of life(BPH-QOL)scale was used to assess quality of life before surgery,3 months after surgery,and 6 months after surgery.The incidence of complications such as urethral stricture,urinary tract irritation,bladder neck contracture,urinary retention,and secondary bleeding was compared between the two groups.Results The operation time of patients in the observation group was significantly longer than that in the control group,the intraoperative blood loss was significantly less than that in the control group,and the bladder irrigation time,catheter indwelling time,and hospitalization time were significantly shorter than those in the control group(P＜0.05).There was no statistically significant difference in the quality of prostatectomy between the two groups of patients(P＞0.05).Before surgery,there was no statistically significant difference in the levels of serum TNF-α,IL-6,MDA,and LPO between the two groups of patients(P＞0.05).On postoperative days 3 and 7,the levels of serum TNF-α,IL-6,MDA,and LPO in both groups were significantly higher than those before surgery,and the levels of serum TNF-α,IL-6,MDA,and LPO in the observation group were significantly lower than those in the control group(P＜0.05).Before surgery,there was no statistically significant difference in the IPSS and USDS scores between the two groups of patients(P＞0.05).At 3 and 6 months after surgery,the IPSS and USDS scores of patients in both groups were significantly lower than those before surgery,and the IPSS and USDS scores of patients in the observation group were significantly lower than those in the control group(P＜0.05).Before surgery,there was no statistically significant difference in RUV,Qmax,and serum tPSA levels between the two groups of patients(P＞0.05).At 3 and 6 months after surgery,the RUV and serum tPSA levels of patients in both groups were significantly lower than those before surgery,while the Qmax was signifi-cantly higher than that before surgery(P＜0.05).The RUV and serum tPSA levels of patients in the observation group were significantly lower than those in the control group,while the Qmax was significantly higher than that in the control group(P＜0.05).Before surgery,there was no statistically significant difference in the IIEF-5 and BPH-QOL scores of patients between the two groups(P＞0.05).At 3 and 6 months after surgery,the IIEF-5 scores of patients in both groups were significantly lower than those before surgery,while the BPH-QOL scores were significantly higher than those before surgery(P＜0.05).The IIEF-5 and BPH-QOL scores of patients in the observation group were significantly higher than those in the control group(P＜0.05).The total incidence of complications in the control group and the observation group was 16.67％(10/60)and 5.00％(3/60),respectively,and the total incidence of complications in the observation group was significantly lower than that in the control group(x2=4.227,P＜0.05).Conclusion Green laser anatomical vaporization in the treatment of BPH patients with T2DM can optimize the surgical process,reduce inflammatory stress and the risk of complications,promote early postoperative recovery,improve urodynamics and sexual function,relieve symptoms,and enhance quality of life.
