Introduction: In China, patients with chronic cholecystitis account for approximately 10% of the total population, in which over 90% of cholecystitis is caused by cholelithiasis. This study aimed to discuss the possible mechanism of electroacupuncture on the Yanglingquan acupoint promoting gallbladder contractibility of patients with chronic cholecystitis. Methods: 60 patients were randomly divided into a trial group and a control group. Doppler ultrasound and color Doppler blood flow imaging was applied. The trial group adopted the BT701-1B electroanesthesia apparatus to perform electroacupuncture on the bilateral acupoints of Yanglingquan, while electroacupuncture was made on sham acupoints in the control group. Results: Before the electroacupuncture, gallbladder volume was 49.6 ± 5.66 ml, after 15 min and 30 min of electroacupuncture, the gallbladder volume was then 32.9 ± 5.66 ml and 23.0 ± 2.83 ml respectively. The comparison before and after electroacupuncture was obviously and statistically different (P < 0.01). The comparison between after 15 min and 30 min is obviously statistically different (P < 0.01). Before the electroacupuncture, the gallbladder artery Vmax, Vmin, and RI were 18.4 ± 2.69 cm/s, 9.7 ± 0.07 cm/s, and 0.47 ± 0.06, respectively; the cystic artery Vmax, Vmin, and RI after 30 min were 8.1 ± 0.92 cm/s, 3.1 ± 0.57 cm/s, and 0.61 ± 0.02. The comparison in gallbladder artery Vmax and Vmin and the drag index (RI) before and after electroacupuncture was obviously and statistically different (P < 0.01). Conclusions: Electroacupuncture on the acupoints of Yanglingquan has the potential to promote the emptying of the gallbladder. The mechanism may be related to that the smooth muscle of the gallbladder contracts after electroacupuncture and the gallbladder empties.

 Today is the era of modernization and fast life. Everybody is busy and living stressful life. Changing life style of person has created many disharmonies in his biological system. Advancement of busy, professional life and social life, improper sitting posture, continuous work in one posture, jerking movements during travelling and sports, all these factors create undue pressure and stress injury to spine and play an important role in producing disease like cervical spondylosis. In this study total 70 patients of Cervical Spondylosis having signs and symptoms of same, selected from OPD of our hospital. Patients were divided into two groups, 35 patients in control group and 35 patients in trial group. Patients in trial group were advised to Practice Makarasan as per yoga module adapted during study and Patients in control group were advised to do Neck Exercise as per neck exercise module adapted during study for 90 days daily. Assessment was done on the basis of pain, tenderness, stiffness and x-ray report of cervical spine before and after study. Makarasan is significantly effective in reduction of signs and symptoms of cervical spondylosis but there were no changes seen in anatomical structures in patients of cervical spondylosis after intervention of Makarasan.

Blood Flow Imaging

Abstract Objective: The objective of this study was to investigate the clinical applicability of navigated blood flow imaging (BFI) in neurovascular applications. BFI is a new 2-dimensional ultrasound modality that offers angle-independent visualization of flow. When integrated with 3-dimensional (3D) navigation technology, BFI can be considered as a first step toward the ideal tool for surgical needs: a real-time, high-resolution, 3D visualization that properly portrays both vessel geometry and flow direction. Methods: A 3D model of the vascular tree was extracted from preoperative magnetic resonance angiographic data and used as a reference for intraoperative any-plane guided ultrasound acquisitions. A high-end ultrasound scanner was interconnected, and synchronized recordings of BFI and 3D navigation scenes were acquired. The potential of BFI as an intraoperative tool for flow visualization was evaluated in 3 cerebral aneurysms and 3 arteriovenous malformations. Results: The neurovascular flow direction was properly visualized in all cases using BFI. Navigation technology allowed for identification of the vessels of interest, despite the presence of brain shift. The surgeon found BFI to be very intuitive compared with conventional color Doppler methods. BFI allowed for quality control of sufficient flow in all distal arteries during aneurysm surgery and made it easier to discern between feeding arteries and draining veins during surgery for arteriovenous malformations. Conclusion: BFI seems to be a promising modality for neurovascular flow visualization that may provide the neurosurgeon with a valuable tool for safer surgical interventions. However, further work is needed to establish the clinical usefulness of the proposed imaging setup.

The neural network algorithm of deep learning was applied to optimize and improve color Doppler ultrasound images, which was used for the research on elderly patients with chronic heart failure (CHF) complicated with sarcopenia, so as to analyze the effect of the deep-learning-based color Doppler ultrasound image on the diagnosis of CHF. 259 patients were selected randomly in this study, who were admitted to hospital from October 2017 to March 2020 and were diagnosed with sarcopenia. Then, all of them underwent cardiac ultrasound examination and were divided into two groups according to whether deep learning technology was used for image processing or not. A group of routine unprocessed images was set as the control group, and the images processed by deep learning were set as the experimental group. The results of color Doppler images before and after processing were analyzed and compared; that is, the processed images of the experimental group were clearer and had higher resolution than the unprocessed images of the control group, with the peak signal-to-noise ratio (PSNR) = 20 and structural similarity index measure (SSIM) = 0.09; the similarity between the final diagnosis results and the examination results of the experimental group (93.5%) was higher than that of the control group (87.0%), and the comparison was statistically significant ( P < 0.05 ); among all the patients diagnosed with sarcopenia, 88.9% were also eventually diagnosed with CHF and only a small part of them were diagnosed with other diseases, with statistical significance ( P < 0.05 ). In conclusion, deep learning technology had certain application value in processing color Doppler ultrasound images. Although there was no obvious difference between the color Doppler ultrasound images before and after processing, they could all make a better diagnosis. Moreover, the research results showed the correlation between CHF and sarcopenia.

Purpose Semi-occluded vocal tract (SOVT) exercises with tubes or straws have been widely used for a variety of voice disorders. Yet, the effects of longer periods of SOVT exercises (lasting for weeks) on the aging voice are not well understood. This study investigated the effects of a 6-week straw phonation in water (SPW) exercise program. Method Thirty-seven elderly subjects with self-perceived voice problems were assigned into two groups: (a) SPW exercises with six weekly sessions and home practice (experimental group) and (b) vocal hygiene education (control group). Before and after intervention (2 weeks after the completion of the exercise program), acoustic analysis, auditory–perceptual evaluation, and self-assessment of vocal impairment were conducted. Results Analysis of covariance revealed significant differences between the two groups in smoothed cepstral peak prominence measures, harmonics-to-noise ratio, the auditory–perceptual parameter of breathiness, and Voice Handicap Index-10 scores postintervention. No significant differences between the two groups were found for other measures. Conclusions Our results supported the positive effects of SOVT exercises for the aging voice, with a 6-week SPW exercise program being a clinical option. Future studies should involve long-term follow-up and additional outcome measures to better understand the efficacy of SOVT exercises, particularly SPW exercises, for the aging voice.

Abstract. This study measured the effect of emotional states on lexical decision task performance and investigated which underlying components (physiological, attentional orienting, executive, lexical, and/or strategic) are affected. We did this by assessing participants’ performance on a lexical decision task, which they completed before and after an emotional state induction task. The sequence effect, usually produced when participants repeat a task, was significantly smaller in participants who had received one of the three emotion inductions (happiness, sadness, embarrassment) than in control group participants (neutral induction). Using the diffusion model ( Ratcliff, 1978 ) to resolve the data into meaningful parameters that correspond to specific psychological components, we found that emotion induction only modulated the parameter reflecting the physiological and/or attentional orienting components, whereas the executive, lexical, and strategic components were not altered. These results suggest that emotional states have an impact on the low-level mechanisms underlying mental chronometric tasks.

SummaryChanges in platelets in 48 patients with uterine myoma before and after hysterectomy with and without ovariectomy were examined. Bilateral ovariectomy in 25 cases (ovariec-tomized group) and unilateral or non-ovariectomy in 23 cases (control group) were performed at the hysterectomy. Platelet count and an appearance rate of secondary aggregation decreased at one day after and increased at one week after the operation, similarly in both the ovariectomized and the control group. The appearance rate of secondary aggregation was reflected in an intensity of aggregation at 5 min after the addition of reagent to PRP. At one month after the operation, the appearance rate of secondary aggregation induced by 3 μM ADP showed a statistically significant decrease in comparison with the preoperation value (P <0.05) and the enhancement of 5-min aggregation was still observed in the control group, while ceased in the ovariectomized group. The difference between the two groups was significant (P < 0.05). There was almost no change in the speed and intensity of primary and secondary aggregation during the observation period. No significant differences in collagen-induced aggregation were noted between the two groups. The results suggest that ovarian hormones, mainly estrogen, facilitate platelet activation which is mediated by the so-called secondary aggregation.
