OBJECTIVE: To observe the clinical efficacy of Fu's subcutaneous needling based on "multi-joint muscle spiral balance chain" theory for cervical vertigo (CV) and its effect on blood flow velocity of vertebral artery. METHODS: A total of 60 patients with CV were randomized into a Fu's subcutaneous needling group and a medication group, 30 cases in each one. In the Fu's subcutaneous needling group, Fu's subcutaneous needling was delivered at Dazhui (GV14), the flexible tube was retained for 5 min after sweeping manipulation, and the treatment was given once every other day, 3 times a week for 3 weeks. In the medication group, betahistine mesylate tablet and diclofenac sodium dual-release enteric capsule were taken orally for continuous 3 weeks. Before treatment, after treatment, and in follow-up of one month after treatment completion, the scores of dizziness handicap inventory (DHI) and visual analogue scale (VAS) were observed; before and after treatment, the blood flow velocity of vertebral artery was measured by transcranial Doppler, and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: After treatment and in follow-up, each item scores and total scores of DHI were decreased compared with those before treatment in the two groups (P<0.05); the VAS scores after treatment in the two groups, as well as the VAS score in follow-up of the Fu's subcutaneous needling group, were decreased compared with those before treatment (P<0.05). In the Fu's subcutaneous needling group, after treatment and in follow-up, the physical scores and the total scores of DHI, and the VAS scores were lower than those in the medication group (P<0.05); in follow-up, the emotional and functional scores of DHI were lower than those in the medication group (P<0.05). After treatment, the mean blood flow velocity (Vm) of the left vertebral artery (LVA) and the right vertebral artery (RVA) was increased compared with that before treatment in the two groups (P<0.05), and the Vm of LVA and RVA in the Fu's subcutaneous needling group was higher than that in the medication group (P<0.05). The total effective rate was 100.0% (30/30) in the Fu's subcutaneous needling group, which was superior to 73.3% (22/30) in the medication group (P<0.05). CONCLUSION Fu's subcutaneous needling based on the "multi-joint muscle spiral balance chain" theory can effectively alleviate the vertigo and neck pain, and improve the blood flow velocity of vertebral artery in CV patients, and has a long-term therapeutic effect.

Objective    To assess the early outcome of transapical transcatheter aortic valve replacement (TAVR) for patients with aortic insufficiency. Methods    The patients with aortic valvular disease who underwent transapical TAVR from October 2020 to October 2022 in the Department of Cardiac and Vascular Surgery, the First Affiliated Hospital of Anhui Medical University were enrolled in the current retrospective study. The patients with aortic stenosis were assembled in a group A, and the patients with aortic insufficiency were assembled in a group B. The improvements of heart function and complications were assessed for the two groups. Results    A total of 56 patients were enrolled, including 32 males and 24 females with an average age of 73.34±5.10 years. There were 31 patients in the group A and 25 patients in the group B. There was no statistical difference between the two groups in the age, gender, height, weight, hypertension, coronary artery disease, peripheral vascular disease, chronic obstructive pulmonary disease, renal disorder or classification of heart function (P>0.05). Also, there was still no statistical difference in the rate of permanent peacemaker implants, emergent open surgery, valve re-implants, or perivalvular leakage (P>0.05). After TAVR, the left ventricular diastolic diameter, left ventricular ejection fraction, complicated moderated mitral and tricuspid regurgitation were significantly improved in both groups compared with preoperative findings (P<0.05); however, there was no statistical difference in these parameters between groups (P>0.05). Conclusion    Interventional valve (J-Valve) in the treatment of patients with aortic insufficiency through transapical TAVR significantly improves cardiac function and reduces functional valve regurgitation.

At present, there still exist some limitations in the laparoscopic surgery robot represented by da Vinci surgical robot, such as the lack of force feedback function. Doctor can not feel the force feedback while operating. In this paper, a new minimally invasive laparoscopic surgery robot system is designed. Based on the master side surgeon's console, stereo vision subsystem and the slave side surgical cart, the multi-dimensional instrument force feedback technology and force feedback based safety protection strategy are introduced. The design realizes the force sensing function of full state operation. Besides, a number of different live pig experiments are carried out. The amount of bleeding in these experiments is relatively small compared with the data of the same kind of surgical robots, which effectively validates the force feedback and surgical safety protection strategies of the new robot system.

Objective:To explore associations of subclinical hypothyroidism (SCH) with endocrine metabolic characteristics in women with polycystic ovary syndrome (PCOS).Methods:A total of 321 women who were newly diagnosed as PCOS were recruited from two endocrine outpatient clinics.The diagnosis of PCOS was established according to the 2003 Rotterdam consensus criteria.Thyroid function was examined by chemiluminescent immunoassay.Patients who had normal free thyroxine (FT4) were divided into different SCH subgroups according to two thyroid stimulating hormone (TSH) cutoffpoints (4.2 and 2.5 mU/L).Endocrine metabolic characteristics in different subgroups were compared and analyzed.Results:In PCOS women with normal FT4,the patients with TSH ≥ 4.2 mU/L had higher prolactin (PRL),luteinizing hormone-to-follicle stimulating hormone ratio,and visceral adipose index (all P<0.05).There were trends toward an increase in triglyceride (P=0.085) and a decrease in high-density lipoprotein cholesterol (HDL-C) (P=0.060) in the patients with TSH ≥ 4.2 mU/L compared with that in the patients with TSH<4.2 mU/L.Also in PCOS women with normal FT4,the patients with TSH ≥ 2.5 mU/L had higher body mass index,PRL,triglyceride,visceral adipose index and lower HDL-C in comparison of that in the patients with TSH<2.5 mU/L (all P<0.05).Conclusion:SCH is associated with more severe endocrine abnormality,dyslipidemia,and visceral obesity in PCOS women.PCOS women with normal FT4 and endocrine metabolic characteristics are more prone to be different between the SCH group and the euthyroid group when setting 2.5 mU/L as a TSH cutoff for SCH,indicating that 2.5 mU/L is a good TSH cutoff for SCH in PCOS women.

Objective To examine cardiotoxicity of anthracyclines and trastuzumab in patients with breast cancer by two dimensional speckle tracking imaging. Methods Fifty-eight human epidermal growth factor receptors-2 (HER2) positive patients with breast cancer treated by anthracyclines and trastuzumab were monitored by echocardiography before treatment (Group A), after completion of anthracyclines (Group B), and at follow-up of 3 months (Group C) and 12months (Group D) after using trastuzumab. LVEDD, IVSTD, PWTD, LVEDV, LVESV were measured in the apical four- and two-chamber views. Left ventricular ejection fraction (LVEF) was measured using a modified Simpson's biplane method. Global longitudinal strain (GLS) and longitudinal strain rate (LSR) were calculated via Qlab8.0 analysis software off-line. Results LVEDDs in A-D groups were (47.95 ±4.12), (48.45 ±4.02), (48.91 ±3.83) and (49.98 ±3.72) mm, respectively, and LVEDVs were (108.70 ±21.26), (111.90 ±20.91), (113.50 ±20.25) and (119.20 ±20.02) ml, respectively. LVEDD, PWTD [(9.14 ±0.76) mm vs. (9.00 ±0.82)mm], LVEDV, LVESV [(54.60 ±14.58) ml vs. (50.97 ±14.35) ml] were increased in group B compared with those in A group (all P<0.05). LVEDD and LVEDV were increased in group C(P<0.05) compared with those in group B. CLVEDD, LVEDV, LVESV [(59.18±13.88) ml vs. (55.23± 13.81) ml] were increased in group D compared with group (P<0.05). Differences of LVEF between group C and group D were statistically significant[(59.48±2.62) % vs. (62.00±1.40) %, P<0.001]. Differences of GLS [(-21.16±2.33)%, (-19.76±1.98) %, (-19.22±1.89) % and (-18.74±1.79) %, respectively, P<0.001] and LSR [(-1.27±0.11), (-1.22±0.09), (-1.17±0.07) and (-1.14±0.06) /s, respectively, P<0.001] among four groups had all statistically significant. Conclusions Longitudinal left ventricle systolic function are impaired in patients with breast cancer treated by anthracyclines and trastuzumab. GLS and LSR of myocardium traced by two dimensional speckle tracking imaging would be useful for early evaluation of the severity.

Objective To observe the correlation between cardiac two-dimension global strain-speckle tracking imaging (2D-STI) and coronary artery disease index (CADi) scores in patients with acute myocardial infarction(AMI). Methods Eighty patients with AMI were chosen and given myocardial motion analysis using 2D-STI. The global longitudinal strain (GLS), global radial strain (GRS) and global circumferential strain (GCS) was calculated. All patients were given scoring according to CADi scores standard by coronary angiography. The correlations between 2D-STI indexes and CADi scores were analyzed. The area under curve(AUC) of the receiver operating characteristic curve (ROC) of critical coronary stenosis was calculated. Results GLS, GRS and GCS was all correlated to CADi scores (r=0.670, -0.621, 0.525, all P < 0.01). The sensitivity, specificity and AUC of GLS for critical coronary stenosis was 82.35%, 80.43% and 0.831. The sensitivity, specificity and AUC of GCS for critical coronary stenosis was 76.47%, 76.09% and 0.797. The sensitivity, specificity and AUC of GRS for critical coronary stenosis was 97.06%, 78.26% and 0.880. The AUC of GLS and GRS was larger than that of GCS, and the sensitivity, specificity for critical coronary stenosis was larger. Conclusions 2D-STI indexes have correlation with CADi scores. GLS and GRS has correlation with coronary artery stenosis.
