miR-135 is a highly conserved miRNA in mammals and includes miR-135a and miR-135b.Recent studies have shown that miR-135b is a key regulatory factor in cardio-cerebrovascular diseases.It is involved in regulating the pathological process of myocardial infarction,myocardial ischemia/reperfusion injury,cardiac hypertrophy,atrial fibrillation,diabetic cardiomyopathy,atherosclerosis,pulmonary hyperten-sion,cerebral ischemia/reperfusion injury,Parkinson's disease,and Alzheimer's disease.Obviously,miR-135b is an emerging player in cardio-cerebrovascular diseases and is expected to be an important target for the treatment of cardio-cerebrovascular diseases.However,the crucial role of miR-135b in cardio-cerebrovascular diseases and its underlying mechanism of action has not been reviewed.Therefore,in this review,we aimed to comprehensively summarize the role of miR-135b and the signaling pathway mediated by miR-135b in cardio-cerebrovascular diseases.Drugs targeting miR-135b for the treatment of diseases and related patents,highlighting the importance of this target and its utility as a therapeutic target for cardio-cerebrovascular diseases,have been discussed.

Objective:To investigate the correlation between serum insulin-like growth factor 1 (IGF-1), thyroid stimulating hormone (TSH), degree of insulin resistance and thyroid nodule imaging reporting and data system (TI-RADS) grading in patients with type 2 diabetes mellitus (T2DM).Methods:The clinical data of 120 patients with T2DM from February 2020 to November 2021 in Kunshan Hospital of Integrated Traditional Chinese and Western Medicine were retrospectively analyzed. Among them, 56 patients had no thyroid nodules (non-thyroid nodule group), all patients were TI-RADS grade 1; 64 patients had thyroid nodules (thyroid nodule group), including 7 cases of TI-RADS grade 2, 12 cases of TI-RADS grade 3, 20 cases of TI-RADS grade 4, and 25 cases of TI-RADS grade 5. The levels of IGF-1 and TSH were measured by automated biochemical analyzer, the homeostatic model assessment insulin resistance index (HOMA-IR) was calculated. Spearman method was used for correlation analysis; multivariate Logistic regression was used to analyze the independent risk factors of TI-RADS grading in patients with T2DM combined with thyroid nodules; the receiver operating characteristic (ROC) curve was drawn to analyze the efficacy of IGF-1, TSH and HOMA-IR in predicting TI-RADS grading in patients with T2DM combined with thyroid nodules.Results:The IGF-1, TSH and HOMA-IR in thyroid nodule group were significantly higher than those in non-thyroid nodule group: (185.35 ± 45.08) ng/L vs. (168.36 ± 30.25) ng/L, (2.98 ± 0.85) mU/L vs. (2.69 ± 0.35) mU/L and 3.25 ± 0.75 vs. 2.95 ± 0.44, and there were statistical differences ( P<0.05 or <0.01). In patients with T2DM combined with thyroid nodules, with the increase of TI-RADS classification, the IGF-1, TSH and HOMA-IR gradually increased, and there were statistical differences ( P<0.05). Spearman correlation analysis result showed that the levels of IGF-1, TSH and HOMA-IR were positive correlation with TI-RADS grading ( r = 0.918, 0.906 and 0.920; P<0.05). Multivariate Logistic regression analysis result showed that the IGF-1, TSH and HOMA-IR were independent risk factors for TI-RADS grading in patients with T2DM combined with thyroid nodule ( OR = 1.684, 1.044 and 1.851; 95% CI 0.674 to 6.665, 0.032 to 0.055 and 1.212 to 2.298; P<0.01 or <0.05). ROC curve analysis result show that the area under the curve of IGF-1, TSH and HOMA-IR for predicting the TI-RADS grading patients with T2DM combined with thyroid nodule were 0.946, 0.983 and 0.975, with all sensitivity of 100.00%, and specificity of 82.14%, 91.07% and 89.29%. Conclusions:There is a correlation between IGF-1, TSH, HOMA-IR and TI-RADS grading in patients with T2DM combined with thyroid nodule, which has some guiding value for clinical monitoring of thyroid nodule changes.

Objective:To analyze the characteristics of vocal fold vibration of normal people and patients with spasmodic dysphonia (SD) using laryngeal high speed videoendoscopy combined with glottal area wave analysis.Methods:This prospective study examined twenty healthy subjects (10 males and 10 females), 12 patients with adductor spasmodic dysphonia(AdSD) (2 males,10 females)as AdSD group and 2 patients with abductor spasmodic dysphonia(AbSD) (2 males) as AbSD group. Twelve of healthy subjects (2 males,10 females) were selected as control group according to AdSD group gender match. All the subjects were recruited from the Department of Voice, Zhongshan Hospital, Xiamen University from October 2019 to December 2020. All subjects underwent laryngeal high speed videoendoscopy and 10 vibration periods were selected from each recording and were used to quantitatively analyze the change of glottal area and vocal fold vibration parameters (Speed Quotient (SQ), Open Quotient (OQ) and Close Quotient (CQ)).Results:1. There were statistically significant differences in SQ, CQ and OQ between males and females in the healthy subjects ( t=12.28, 5.59, 5.59, P<0.05). The change of the glottal area during each vibration period in healthy subjects was relatively stable(0.19-0.42). 2. The change of the glottal area during each vibration period in AdSD subjects had larger fluctuations, with the glottal area change index fluctuating in the range of 0.31 to 0.62. The SQ value of the AdSD group was significantly lower than that of control group ( t=4.246, P<0.05). There were no significant differences in OQ and CQ between AdSD group and normal group ( t=1.064, 1.332, P>0.05); The SQ value of the AbSD group tended to increase compared to normal group. Conclusions:Laryngeal high speed videoendoscopy combined with glottal area wave analysis has a certain reference value in the studying the vibration characteristics of SD patients. SQ has good specificity.

Objective To indentify the cognitive status of Chinese patients to acne and the influencing factors to theirs' cognitive status,so as to provide solid evidences for the prevention and treatment of acne.Methods A self-designed questionnaire was made to conduct this survey of 16,156 acne patients,who seeked to the treatment in the dermatological departments from 112 hospitals in China.The survey consisted of several parts,including the general status of patients,the patients' cognition of occurrence,development and risk factors of acne,whether the first choice was seeking treatment at the hospital when the patients had acne and the condition of selection of skin care products.The factors were analyzed,which could impact the cognition of the patients' behavior of treatment,how did the patients' cognition to influence their medical behavior and skin care as well as the consistency of assessment of the severity of acne by doctors and patients themselves.Results The acne patients studied had the best knowledge of "acne is a skin disease","it not only occurs in the period of adolescence" and "the disease can be prevented and cured",which accordingly accounted for 80.65％,69.16％ and 65.49％ of the total patients respectively.However,the awareness of acne patients to heredity,high sugar and dairy products as risk factors for acne was insufficient,which accounted for 48.72％,42.40％ and 18.25％ of the total patients,respectively.Gender,age,educational level,occupation and health knowledge were the main factors affecting the cognitive level of patients;the survey also found that men,patient with educational level of junior high or even lower educational condition,occupation of labor workers or farmers and patients were lack of health education with poor knowledge of the genetics and dietary were risk factors for acne;patients with age over 36 years or with mild illness had poor knowledge of dietary risk factors for acne;the difference was statistically significant (P＜0.05).The analysis of the influence of cognitive status on medical treatment behavior and skin care showed that the better the cognition,the higher the probability of patients would choose medical treatment as the first choice as well as choosing functional skin care products;the difference was statistically significant (P＜0.05).The consistency of assessment of the severity of acne by doctors and patients was poor (Kappa value ＜0.4),and the assessment of severity of acne by patients was more serious than doctors' assessment.Conclusions Patient's cognitive status will affect their medical behavior and skin care,and there is also a phenomenon that patients have a more serious assessment of their acne condition.It is suggested that health education for acne patients should be strengthened in clinical medicine so as to improve their knowledge of acne as well as preventing from acne effectively.

Objective: To discuss the clinical effect of small dose of botulinum toxin injection in cricothyroid muscle and thyroarytenoid muscle on patients with incomplete bilateral recurrent laryngeal nerve paresis. Methods: Six patients were selected with Ⅰor Ⅱ or Ⅲ degree of dyspnea diagnosed as bilateral recurrent laryngeal nerve injury by laryngeal electromyography, and small dose of botulinum toxin injection was performed in cricothyroid muscle and thyroarytenoid muscle as a treatment. Degree of dyspnea was assessed one month before and after the treatment, and the stroboscopic laryngoscope results, acoustic parameters and CT image of the patients were collected in the 6 patients. The relevant parameters were also collected one month before and after treatment, including the degree of dyspnea, stroboscopic laryngoscope results, acoustic parameters and CT image of the patients. The angle between bilateral vocal cords in stroboscopy at full inspiratory was calculated, acoustic parameters (F0, jitter, shimmer) were analysed, and vocal length, width and the vocal region were measured. Then, the paired t test was performed for statistical analysis between before and after one month injection, the one way analysis of variance was performed among vocal parameters in CT image. Result: Botulinum toxin injection was successfully completed in the 6 patients, followed without any serious complications. The degree of dyspnea was alleviated to some extent after treatment in all 6 patients; the angle between bilateral vocal cords at the end of a deep inspiration was significantly increased (t=2.44, P<0.05) after the treatment. The changes of F0 and jitter between before and after treatment were not statistically significant (t=0.72, t=1.42, P>0.05). Shimmer was significantly decreased after treatment (t=2.61, P<0.05). Vocal fold length, width and vocal region increased with F0, there was a statistically significant difference between different F0 before injection, and there was no statistically significant difference between different F0 after injection. The follow-up time was respectively seven months, 1 year, 1 year, 18 months, 22 months and 2 years respectively. Conclusion Small dose of botulinum toxin injection in bilateral cricothyroid muscles and thyroarytenoid muscles can relieve the dyspnea caused by bilateral vocal cords paresis to some extent, accompanied without serious complications, despite the sound quality was slightly worse.

Objective To explore the value of prenatal ultrasound in diagnosis of omphalocele-exstrophy-imperforate anusspinal defects (OEIS) in first trimester.Methods Prenatal ultrasonic characteristics of 10 fetuses with OEIS complex in first trimester were retrospectively analyzed and compared with autopsy results.Results Cystic bulging in the lower anterior abdominal wall was observed in all 10 fetuses.Spinal scoliosis dysplasia was found in 10 fetuses,with myelomeningocele in 3 fetuses.No normal bladder was visualized in 8 fetuses.Thickened nuchal translucency was noticed in 5 fetuses,among which neck lymphatic hydrocele was found in 1 fetus.The bilateral clubbed feet and left lower mutilation was observed in 1 fetus,respectively.All 10 OEIS complex fetuses were found accompanied with short umbilical cord,while single umbilical artery and umbilical cord cyst were found in 4 and 1 fetus,respectively.Autopsy showed abdominal wall defects with exstrophy in 10 fetuses.However,no complete cystic bulging was found.Besides,autopsy also showed pubic symphysis separation and bladder exstrophy in 10 fetuses without obvious genitalia nor anus.Conclusion Cystic bulging in the lower anterior abdominal wall is the most common prenatal ultrasonic characteristic of OEIS complex in first trimester.

Objective To study the effect of sub-glottal convergence angle on the degree of glottal closure, and to analyze the potential mechanism of dysphonia by the incomplete glottal closure.Methods Three vocal fold positions (adduction, intermediate and abduction) were evaluated by the degree of glottal closure, and divided into three groups.The neck CT images of the subjects were gathered.The vocal folds were adduction group when the normal subjects made a sustaining phonation /i:/ during CT scanning;the vocal folds were abduction group when the normal subjects made a deep breathing during CT scanning, and the unilateral vocal folds were incomplete closing group when the unilateral vocal fold paralysis subjects made a deep breathing during CT scanning.3D models of the vocal folds and the airway were reconstructed using Mimics software, through which the sub-glottal convergence angle was measured.Using one-way factor analysis of variance, we compared the angle among three groups.Results The angle changed with degree of glottal closure, with statistically significant differences among the three groups(P<0.01).The means of the angle in three groups were 33.49°±3.75°, 55.03°±2.61° and 75.02°±7.32°.Conclusion The 3D model generation from CT data is an effective method of measuring the sub-glottal convergence angle, while the angle changes with the degree of glottis closure.The angle may affect sub-glottal pressure distribution in the sub-glottal shear or normal direction and influence vocal fold vibration, which would make vibration and vocal fold mucosal wave generation more difficult, and might cause dysphonia.

Objective To observe the clinical efficacy of surround electroacupuncture in relieving pain after operation for mixed hemorrhoids. Method Seventy-two patients with mixed hemorrhoids were randomized into a treatment group and a control group, 36 cases in each group. The two groups both received the corresponding interventions once in 15 min after the operation: the treatment group received electroacupuncture treatment, and the control group was only placed in a simulated environment of electroacupuncture but without receivimg any needling treatment. The pain intensity was evaluated by using Verbal Rating Scale (VRS), Wong-Baker Faces Pain Rating Scale, and Visual Analogue Scale (VAS) at 11 different time points after the treatment: once every 1 h in 8 h after the treatment, once at the first defecation, once respectively 24 h and 48 h after the treatment. The data were statistically analyzed afterwards. Result At 3 h and 4 h after the treatment and at the first defecation after the treatment, the VRS scores of the treatment group were significantly lower than that of the control group (P<0.05); respectively at 4 h, 5 h, 6 h, 7 h, and 8 h after the treatment and at the first defecation, the Wong-Baker scores of the treatment group were significantly lower than that of the control group (P<0.05); respectively at 2 h, 3 h, 4 h, 5 h, 6 h, 7 h, and 8 h after the treatment, at the first defecation, as well as at 24 h after the treatment, the VAS scores of the treatment group were significantly lower than that of the control group (P<0.05); it indicates that the pain intensity of the treatment group should be lower than that of the control group at the above time points, and the analgesic effect in the treatment group lasts a longer time, running a lower risk of losing effectiveness compared to the control group (P<0.05). Conclusion Real-time acupuncture treatment after the operation is significantly effective in relieving pain after operation for hemorrhoids.

Objective To evaluate the therapeutic effect of computerized online cognitive training for children with attention deficit hyperactivity disorder (ADHD).Methods Fifteen children with ADHD recruited from Department of Neurology in the Children's Hospital Affiliated to Capital Institute of Pediatrics received computerized online cognitive training including attention training,visual spatial training and memory training.Cognitive neuropsychological test battery (choice reaction time,mental rotation,word semantic,simple subtraction,working memory and visual tracing) was used to assess the cognitive function in pre-training and post-training stages,such as basic response ability,reaction speed,visuo-spatial cognitive ability,semantic comprehension,calculation fluency,working memory and attention ability.Paired-samples t test was used to make comparison of the cognitive test results between pre-training condition and post-training condition.Results All the correction scores of cognitive tests were transformed to percentile scores.Paired-samples t test results showed that the ADHD children got higher scores in the post-training condition than in the pre-training condition in working memory test [(52.00 ± 20.77) ％ vs (39.73 ± 23.64) ％,t =2.72,P ＜ 0.05].There was no significant training effect in choice reaction time,mental rotation,sentence completion,simple subtraction and visual tracing(all P ＞ 0.05).Conclusions Computerized online cognitive training can significantly improve the working memory of children with ADHD,and has no side effects on other cognitive functions.It need to further expand the sample size and follow up the training effect for a long-term.

OBJECTIVE: To analysis the acoustic characteristics in patients with unilateral arytenoid dislocation and unilateral vocal fold paralysis, and evaluate the application value of acoustic analysis technique in these two diseases. METHOD: The voice signals of sustained vowel /a/ were measured using the software MDVP in 50 healthy adults and 67 patients with unilateral vocal cord movement disorders. The acoustic parameters (jitter, shimmer, NHR and F₀) were analyzed. All patients were divided into arytenoid dislocation group (36 cases) and vocal fold paralysis group (31 cases) through the laryngeal electromyography. All groups were divided into male and female group again. The acoustic characteristics between the two experimental groups and normal control groups were observed and compared. Results were analyzed using Rank sum test. RESULT: (1) In both male or female groups, there were significant differences in jitter and shimmer between two experimental group and control group. In both male or female groups, there were significant differences in NHR between arytenoid dislocation group and control group. There were no significant differences in NHR between vocal fold paralysis group and control group. Except for the male vocal fold paralysis group, there were significant differences in F between the other experimental groups and control groups. (2) In both male or female groups, there were no significant differences in jitter and shimmer between vocal fold paralysis group and arytenoid dislocation group. There were significant differences in NHR. CONCLUSION The acoustic parameters are effective parameters to measure the voice quality of patients with unilateral arytenoid dislocation and unilateral vocal fold paralysis. NHR is the most sensitive parameter in the distinction of vocal cord paralysis and arytenoid dislocation.
