BACKGROUND:Transposition of the long head of biceps tendon is a commonly surgical method for massive rotator cuff tears.Currently,there are a few reports on the clinical efficacy of the transposition of the long head of biceps tendon and there is no consensus on the influencing factors for retearing. OBJECTIVE:To observe the outcome of arthroscopic long head of the biceps tendon in the treatment of massive rotator cuff tear. METHODS:The clinical data of 28 patients with massive rotator cuff tears,aged(61.79±10.50)years,admitted at Jiangsu Province Hospital of Chinese Medicine from March 2019 to May 2022 were retrospectively analyzed.All patients underwent arthroscopic long head of the biceps tendon.Patients were assessed for visual analog scale scores,University of California at Los Angeles scores,American Shoulder and Elbow Surgeons scores,Constant-Murley scores,and shoulder range of motion before and 1 year after operation.MRI of the shoulder joint was performed for observing the integrity of the repaired structure at 1 year after operation.Twenty-three patients(5 of 28 lost to follow-up)were categorized into the intact tendon group(n=18)and the tendon retear group(n=5)according to the Sugaya typing at 1 year after operation;the patients were divided into the normal group(n=8),the degeneration group(n=9),and the partial tear group(n=6)according to the intraoperative quality of the long head of the biceps tendon.Differences in the above indexes were compared between groups. RESULTS AND CONCLUSION:When followed up at 1 year after surgery,the range of motion,visual analog scale scores,University of California at Los Angeles scores,American Shoulder and Elbow Surgeons scores,Constant-Murley scores of the shoulder were significantly improved compared with preoperative data(P＜0.05).There was a significant difference in Goutellier grading between intact tendon and tendon retear groups(P＜0.05),while no significant difference was observed in the other influencing factors(P＞0.05).There were no significant differences in visual analog scale scores,University of California at Los Angeles scores,American Shoulder and Elbow Surgeons scores,Constant-Murley scores,and shoulder range of motion at 1 year after operation among the normal,degeneration,and partial tear groups(P＞0.05).MRI findings indicated that the sutured tendon healed well in 18 patients,with a healing rate of 78%.Arthroscopic long head of the biceps tendon for augmented repair can provide a reliable repair for massive rotator cuff tear that is refractory,significantly alleviate the pain of the shoulder joint,and restore the function of the shoulder joint.

Objective To explore the effect of sling exercise with Tuina therapy on kinesiophobia in old patients with lumbar disc herniation,and analyze the mechanism based on brain-bone axis. Methods A total of 56 old patients with chronic lumbar disc herniation and kinesiophobia were selected from the Reha-bilitation Hospital of the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine from September,2022 to December,2023;and randomly divided into control group(n=28)and experimental group(n=28).The control group accepted conventional exercise therapy,while the experimental group accepted sling exercise with Tuina therapy,for four weeks.They were assessed with simplified Chinese version of Tampa Scale of Kinesiophobia(TSK),Japanese Orthopaedic Association score(JOA)and Visual Analogue Scale for pain(VAS)before and after treatment,while the bone mineral density(BMD)was tested,the levels of osteoprote-gerin(OPG),norepinephrine(NE)and corticosteroids(Cor)in serum were measured,and the median frequency(MF)of weak-link erector spinae was detected with surface electromyography. Results Two cases dropped off in the control group,and one in the experimental group.The scores of all the assessment improved in both groups after treatment(|t|>14.168,P<0.001),as well as the serum levels of OPG,NE and Cor(|t|>2.103,P<0.05),BMD(|t|>2.726,P<0.05),and MF of erector spinae(|t|>14.736,P<0.001);all of them were better in the experimental group than in the control group(|t|>2.154,P<0.05). Conclusion Sling exercise with Tuina therapy can improve the pain and kinesiophobia of lumbar disc herniation in the old adults,which may promote the recovery of physical and mental function through regulating the levels of hor-mones and neurotransmitters related to the brain-bone axis.

Objective:To investigate the risk factors and their warning effectiveness for meniscus tear secondary to delayed anterior cruciate ligament (ACL) reconstruction.Methods:A retrospective cohort study was conducted to analyze the clinical data of 114 patients (114 knees) with ACL injury, who were admitted to Affiliated Hospital of Nanjing University of Chinese Medicine from December 2018 to December 2023, including 78 males and 36 females, aged 11-50 years [29(21, 35)years]. The patients were divided into tear group ( n=46) and non-tear group ( n=68) according to whether combined with meniscus tear or not during the surgery. Gender, age, duration of disease, smoking history, Body Mass Index (BMI), cause of injury, mechanism of injury, side of the injury, Beighton score, difference of KT-2000 examination, Tegner activity scale of the knee joint, anterior tibial translation sign, medial posterior tibial slope angle, lateral posterior tibial slope angle, and pivot shift grading of the patients in the two groups were recorded. Correlations between the above-mentioned indicators and occurrence of meniscus tear secondary to delayed ACL reconstruction were assessed. In the meantime, the independent risk factors were determined by univariate and multivariate binary logistic regression analysis. Receiver operating characteristic (ROC) curve and area under curve (AUC) were used to evaluate the warning effectiveness of each risk factor for meniscal tear secondary to delayed ACL reconstruction. Results:Univariate analysis showed correlation of duration of disease, BMI, Tegner activity scale of the knee joint, medial posterior tibial slope angle, lateral posterior tibial slope angle and high-grade pivot shift with occurrence of meniscus tear secondary to delayed ACL reconstruction ( P<0.01). The results of multivariate binary logistic regression analysis showed that the duration of disease ≥14.5 weeks ( OR=1.20, 95% CI 1.05, 1.38, P<0.01), BMI≥26.9 kg/m 2 ( OR=1.36, 95% CI 1.03, 1.81, P<0.05), Tegner activity scale of the knee joint ≥4 points ( OR=2.29, 95% CI 1.18, 4.46, P<0.05), medial posterior tibial slope angle ≥11.2° ( OR=2.27, 95% CI 1.06, 4.89, P<0.05) and high-grade pivot shift ( OR=0.03, 95% CI 0.01, 0.03, P<0.05) were significantly correlated with occurrence of meniscus tear secondary to delayed ACL reconstruction. Results of ROC curve analysis showed that the medial posterior tibial slope angle (AUC=0.86, 95% CI 0.80, 0.93) and duration of disease (AUC=0.85, 95% CI 0.77, 0.92) had good warning value, BMI (AUC=0.78, 95% CI 0.69, 0.87) and Tegner activity scale of the knee joint (AUC=0.73, 95% CI 0.64, 0.83) had ordinary warning value, and the warning value of high-grade pivot shift (AUC=0.60, 95% CI 0.49, 0.71) was the lowest. The combination of the risk factors revealed superior warning effectiveness for meniscus tear second to delayed ACL reconstruction (AUC=0.97, 95% CI 0.96, 1.00). Conclusions:The duration of disease ≥14.5 weeks, BMI ≥26.9 kg/m 2, Tegner score ≥4 points, medial posterior tibial slope angle ≥11.2°and high-grade pivot shift are independent risk factors for meniscus tear secondary to delayed ACL reconstruction. The medial posterior tibial slope angle and duration of disease have good warning value, BMI and Tegner scores have ordinary warning value and high-grade pivot shift has the lowest warning value. The combination of the above risk factors has better warning effectiveness for meniscus tear secondary to delayed ACL reconstruction.

Cancer genomics has led to the discovery of numerous oncogenes and tumor suppressor genes that play critical roles in cancer development and progression.Oncogenes promote cell growth and proliferation,whereas tumor suppressor genes inhibit cell growth and division.The dysregulation of these genes can lead to the development of cancer.Recent studies have focused on non-coding RNAs(ncRNAs),including circular RNA(circRNA),long non-coding RNA(lncRNA),and microRNA(miRNA),as therapeutic targets for cancer.In this article,we discuss the oncogenes and tumor suppressor genes of ncRNAs associated with different types of cancer and their potential as therapeutic targets.Here,we highlight the mechanisms of action of these genes and their clinical applications in cancer treatment.Understanding the molecular mechanisms underlying cancer development and identifying specific therapeutic targets are essential steps towards the development of effective cancer treatments.

Objective To investigate the relationship between daily intake of B vitamins(vitamins Bl,B2,B6 and niacin)and chronic constipation and chronic diarrhea.Methods Data of 3 durations(2005-2006,2007-2008 and 2009-2010)from National Health and Nutrition Examination Survey(NHANES)database were collected and retrospectively analyzed.For the 13 788 participants,their intake of vitamin B1,B2,B6,and niacin were assessed through a 24-hour dietary recall interview.Multivariate logistic regression analysis was employed to explore the correlation between B vitamins and chronic constipation and chronic diarrhea.Additionally,sensitivity analysis and curve fitting correlation analysis were conducted to further elucidate the observed relationships.Results Among the subjects who were enrolled in the study,2 520(18.28％)were diagnosed with chronic constipation,while 2 138(15.51％)were diagnosed with chronic diarrhea.Multivariate logistic regression analysis and sensitivity analysis indicated linear correlations between the intake of vitamin B1,niacin and vitamin B6 and the occurrence of chronic constipation and chronic diarrhea.An increase in the daily intake of these nutrients potentially reduced the risk of chronic constipation,but also increased the risk of chronic diarrhea(P＜0.05).Conclusion Daily intake of vitamins B1,B2,B6 and niacin is correlated with the occurrence of chronic constipation and chronic diarrhea.

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 observe the effects of electroacupuncture (EA) at Neiguan (PC6) on arrhythmia during acute myocardial ischemia-reperfusion and the expression of connexin 43 (Cx43) in rats. Methods: A total of 40 Sprague-Dawley male rats were used. Ten rats were randomly selected as the blank group, and the remaining 30 rats were randomly divided into a model group and an EA group, with 15 rats in each group. Before modeling, rats in the EA group received one session of EA intervention at bilateral Neiguan (PC6) for 30 min; the other groups were treated with the same grasping and anesthesia for 30 min without intervention. PowerLab physiological recorder was used to record electrocardiograph within 30 min of infarction. After the experiment, cardiac tissue and serum were collected from rats. Hematoxylin-eosin (HE) staining was used to observe the morphological changes of myocardial tissue in the ventricular infarction area of rats in each group. The expression of Cx43 protein in the myocardium of each group was detected by Western blotting (WB). Enzyme-linked immunosorbent assay (ELISA) was used to determine the activity of Na+-K+-ATPase in myocardial tissue and the serum content of endogenous digitalis-like factor (EDLF) in rats. Results: There was no statistical difference in arrhythmia score between the EA group and the model group, but the total duration and average duration of arrhythmia in the EA group were decreased (P<0.01). HE staining showed that compared with the blank group, myocardial cells in the model group were disorganized and seriously damaged. The pathological changes in the EA group were similar to those in the model group, but the damage was relatively minor. The results of WB showed that compared with the blank group, the Cx43 expression in myocardial tissue of the model group was decreased (P<0.01); compared with the model group, the Cx43 expression in the EA group was increased (P<0.01); compared with the blank group, the Na+-K+-ATPase activity in myocardial tissue of the model group was significantly decreased (P<0.01); compared with the model group, the Na+-K+-ATPase activity in the EA group was increased (P<0.01). ELISA results showed that compared with the blank group, the serum EDLF content in the model group was significantly increased (P<0.01); compared with the model group, the EDLF content in the EA group was decreased (P<0.01). Conclusion: EA at Neiguan (PC6) can delay and reduce the onset of arrhythmia during myocardial infarction in the rat model of myocardial ischemia-reperfusion. Its mechanism of action may be related to the regulation of the Cx43 expression in myocardial tissue, improvement of the activity of Na+-K+-ATPase in myocardial tissue, and increase in the content of serum EDLF.

Objective:To explore the pathological mechanism of SN hyperechogenicity by investigating the characteristics of substantia nigra (SN) hyperechogenicity on transcranial sonography (TCS) and serum iron metabolism parameters in the postural instability gait difficulty and tremor dominant subtypes of Parkinson′s disease (PD), and the correlation between them.Methods:A total of 155 PD patients recruited in Parkinson′s Disease Specialty in the Second Affiliated Hospital of Soochow University from January 2019 to December 2021 were divided into postural instability gait difficulty group( n=95) and tremor dominant group( n=60). Meanwhile, 49 healthy gender- and age-matched healthy individuals who sought for physical examination during the same period were included as the control group. All subjects underwent TCS and blood test, and the echo of SN between the postural instability gait difficulty group and tremor dominant group, serum iron metabolism parameters among the three groups were compared. The postural instability gait difficulty group and tremor dominant group were subdivided into with SN hyperechogenicity (SN+ )subgroup and without SN hyperechogenicity (SN-) subgroup respectively according to TCS results, and the differences in serum iron metabolism parameters between the subgroups were further compared. The association between SN hyperechogenicity and serum iron metabolism parameters of the postural instability gait difficulty group and tremor dominant group were further analyzed. Results:The total area of bilateral SN+ , the area of SN+ on the larger side, and the ratio of the total area of SN+ to the midbrain area (S/M) in postural instability gait difficulty group were larger than those in tremor dominant group (all P<0.001). The value of serum ceruloplasmin and transferrin in both postural instability gait difficulty group and tremor dominant group were lower than those in control group (all P<0.001), and compared with tremor dominant group and control group, the postural instability gait difficulty group had lower serum ferritin(all P<0.01). In both postural instability gait difficulty group and tremor dominant group, serum ceruloplasmin in SN+ subgroup was lower than that in SN-subgroup ( P=0.001, 0.032). Moreover, there was a negative correlation between serum transferrin and the area of SN hyperechogenicity in two subgroups(postural instability gait difficulty group: rs=-0.454, P<0.001; tremor dominant group: rs=-0.494, P<0.001). Conclusions:Compared with the tremor dominant patients, the postural instability gait difficulty patients have larger area of SN hyperechogenicity and lower serum ferritin level. The area of SN hyperechogenicity is significantly negatively correlated with serum transferrin level, indicating that the production of this imaging characteristics is related to iron metabolism.

Objective To systematically evaluate the adult intraoperatively acquired pressure injury risk prediction model.Methods Related study on IAPI risk prediction model in Chinese and English databases such as CBM,CNKI,PubMed and Web of Science were searched.The language is limited to Chinese and English,and the search time is until November 4,2022.Two researchers independently screened the literature and extracted the data,and applied the bias risk assessment tool of prediction model research to analyze the bias risk and applicability of the included literature.Results 13 articles were included,including 17 models(operation time,age,diabetes,BMI and serum albumin are the most commonly used predictors).Among the 17 models,the area under the curve of 14 models was 0.616 to 0.984,and the other study did not report the AUC results.Among the 13 studies,10 had good applicability,while the remaining 3 had unclear applicability.13 studies have a high risk of bias,mainly because the included studies are retrospective studies,the predictive factors are screened based on univariate analysis,and the predictive outcomes are not defined by guidelines or standardization.Conclusions The existing IAPI risk prediction model for adults has good applicability,but the risk of bias is high,and the construction is not perfect.It is necessary to pay attention to the effectiveness of different risk assessment methods in the later construction,so as to get a better and more accurate risk prediction model and provide some reference and basis for formulating relevant prevention strategies.

Objective:To explore the adjunctive diagnostic value of transcranial sonography (TCS) combined with olfactory test in early Parkinson′s disease (PD) and the clinical value of both in the cognitive function of PD patients.Methods:TCS and olfactory test were performed in 157 early PD patients(PD group) and 157 healthy controls(control group) in the Second Affiliated Hospital of Soochow University from January 2018 to January 2022. The differences in clinical characteristics, TCS, and olfactory test results between the two groups were analyzed. The values of TCS, olfactory test, and their combination in diagnosing early PD were evaluated using clinical diagnosis as the gold standard. The correlations of the midbrain area, the midbrain substantia nigra hyperechoic area, and the third ventricle width in TCS examination with the cognitive score were analyzed in the PD group. According to the olfactory test scores, 157 patients with early PD were divided into two groups: 110 cases of PD with olfactory dysfunction (PD-OD) and 47 cases of PD without olfactory dysfunction (PD-NOD). The differences in clinical scores and TCS results between the two groups were compared.Results:The midbrain substantia nigra hyperechoic area, substantia nigra hyperechoic positivity rate, third ventricle width, and olfactory dysfunction rate were higher in the PD group compared to the control group, while the midbrain area and olfactory test scores were lower than those in the control group (all P<0.001). The sensitivity and the coincidence rate of TCS combined with the olfactory test for early PD diagnosis (90.0%, 77.1%) were higher than those of TCS alone (60.0%, 71.3%) and olfactory test alone (70.1%, 72.3%), but the specificity (63.7%) was lower than that of both alone (82.8% for TCS and 75.2% for olfactory test), (all P<0.001). MoCA score, visual space and executive ability, memory, attention, and language were positively correlated with the area of the midbrain ( rs=0.38, 0.32, 0.27, 0.25, 0.23; all P<0.05) and negatively correlated with the width of the third ventricle ( rs=-0.39, -0.22, -0.39, -0.22, -0.32; all P<0.05), and orientation was negatively correlated only with the width of the third ventricle ( rs=-0.24, P<0.05). The MoCA score of PD-OD group[22(18, 25)] was lower than that of PD-NOD group[24(20, 26)]( P=0.040). Conclusions:The combination of TCS and olfactory test can enhance the sensitivity and diagnostic agreement rate for early PD diagnosis, providing some auxiliary value. The cognitive function of PD patients is positively correlated with the midbrain area and negatively correlated with the width of the third ventricle. The cognitive function of PD patients with olfactory dysfunction is lower than that of PD patients without olfactory dysfunction. TCS and olfactory test may help assess cognitive function in PD patients.
