Objective To observe the effect of yang-supplementing moxibustion in improving the muscular spasm, motor function, and activities of daily living (ADL) of patients with post-stroke hemiplegia.Method Totally 120 patients with post-stroke limb spasm due to qi deficiency and blood stagnation were randomized into group A, B, and C, 40 cases in each group. Group C was intervened by conventional treatment, group A was by yang-supplementing moxibustion in addition to the conventional treatment, and group B was by fire therapy in addition to the conventional treatment. The modified Ashworth Scale (MAS), Fugl-Meyer Scale (FMS), and Barthel Index (BI) were observed before and after intervention.Result Respectively after 1-month and 2-month treatment, the MAS, FMS, and BI scores were significantly different from that before intervention in the 3 groups (P<0.01). After 1-month and 2-month treatment, the MAS, FMS, and BI scores in group A were significantly different from that in group B and group C (P<0.05), and the scores in group B were significantly different from that in group C (P<0.05).Conclusion Yang-supplementing moxibustion can effectively improve the post-stroke limb spasm, and can promote the recovery of motor function.

Objective:To explore the expression and clinical significance of miR-143 in papillary thyroid cancer (PTC) .Methods:Tumor samples and adjacent tissues from 52 patients with PTC were obtained from Jan. 1st, 2018 to Mar. 31st, 2018 in Thyroid Surgery Department of the Affiliated Yantai Yuhuangding Hospital of Qingdao University. Quantitative reverse-transcriptase PCR (RT-qPCR) was used to measure the expression of miR-143 in those subjects. In addition, the relationship between the expression levels of miR-143 and the clinicopathological characteristics was analyzed.Results:RT-qPCR indicated that the expression of miR-143 was down-regulated in PTC, which was significantly lower than that in adjacent tissues ( t=-21.39, 95% CI: 18.20-15.07, P<0.001) . Low expression of miR-143 was related to the number of lymph node metastasis ≥3 in central compartment ( t=10.13, P=0.012) and lateral neck lymph node metastasis ( t=-4.67, P<0.001) . Conclusion:Downregulation of miR-143 in PTC is linked to the metastasis of PTC and may be a potential target for therapeutic intervention.

ObjectiveTo explore the effect of mentality-controlling on local microcirculation of acupuncture at Hegu （LI 4）. MethodsForty healthy subjects were randomly divided into simple acupuncture group and mentality-controlling acupuncture group， with 20 cases in each group. The simple acupuncture group was acupunctured at Hegu （LI 4） on the right hand of the patient. In mentality-controlling acupuncture group， an audio clip was played to guide the participants to control their mentality when needle retention for 5 min after performing acupuncture twirling mani-pulation. The microcirculatory blood perfusion units （MBPU） was captured and compared between groups of participants using laser speckle contrast imaging （LSCI） for 5 mins in each of the four stages， state before acupuncture （R1）， after needle insertion （A1）， after needle twirling （A2） and after needle withdrawal （R2）. The participants' feelings such as relaxation， concentration， drowsiness， energy flow at acupoints were compared between groups， and the adverse reactions were recorded. ResultsThe MBPU values of R1， A1， A2 and R2 stages in mentality-controlling acupuncture group were 67.92±18.40 PU， 168.13±46.03 PU， 144.19±44.40 PU， 159.73±65.21 PU， respectively. The simple acupuncture group were 79.85 （66.80， 99.40）PU， 193.31 （173.15， 224.80）PU， 147.68 （128.12， 198.30）PU， 158.09 （126.05， 207.59）PU respectively. There was a statistically significant difference in MBPU between groups of the four stages （P＜0.01）. Among them， the MBPU in the A1 stage of both groups was significantly larger than that in the R1 stage， the MBPU in the A2 stage significantly smaller than that in the A1 stage， and the MBPU in the R2 stage was significantly larger than that in the R1 stage （P＜0.01）. MBPU in the R2 stage of the mentality-controlling acupuncture group was larger than that in the A2 stage （P＜0.05）. The difference of MBPU between A2 and A1 in mentality-controlling acupuncture group was significantly smaller than that in the simple acupuncture group， and the difference was statistically significant （t = 3.79， P＜0.01）. In mentality-controlling acupuncture group， 18 participants felt relaxed （90%）， 15 concentrated （75%）， 3 felt sleepy （15%）， and 14 felt energy flow at acupoints （70%）； while in the simple acupuncture group， 13 participants felt relaxed and sleepy （65%）， 6 concentrated and 6 felt energy flow at acupoints （30%）. The number of participants with concentration and energy flow at acupoints in mentality-controlling acupuncture group was higher than that in the simple acupuncture group， and the number felt sleepy was lower than that in the simple acupuncture group （P＜0.05）. No needle fainting， needle site infection， local haematoma and any other adverse reactions were found in both groups. ConclusionAcupuncture could affect the changes of local microcirculation， and controlling mentality during acupuncture can slow the rate of MBPU reduction and enhance the post-acupuncture effect with a favourable safety profile.

Objective:To explore the clinical significance of recurrent laryngeal nerve inlet zone(RLNIZ) lymph node metastasis in papillary thyroid cancer(PTC).Methods:The clinical data of the clinicopathologic characteristics of 738 cases with papillary thyroid cancer at our centers from Jul 2017 to Jun 2018 was retrospectively reviewed. 108 cases with RLNIZ lymph node dissection for pathological examination were included. The relationship between metastasis of RLNIZ lymph node and clinicopathologic characteristics was analyzed.Results:RLNIZ lymph node was detected in 12.3%(91/738)cases, the mean lymph node number in RLNIZ was 1.5±0.7, and 30.8%(28/91) cases suffered RLNIZ lymph node metastasis. RLNIZ lymph node metastasis(LNM) is associated with tumor size( P=0.028), capsular invasion( P=0.019), No. of central compartment LNM( P<0.001) and lateral neck LNM( P<0.001). No. of central compartment LNM was found to be the independent risk factor of RLNIZ lymph node metastasis. The incidence of dysphagia and inferior parathyroid damage was 0.9%(1/108)respectively. Conclusions:RLNIZ lymph node metastasis is common among PTC patients , therefore, RLNIZ lymph node should be routinely removed especially in patients with tumor size over 1cm、suspected capsular invasion and lateral neck lymph node metastasis confirmed by preoperative imaging examination.
