Objective To investigate the effect of acupuncture at Huatuo jiaji points plus virtual balancing game on balance function in stroke patients.Methods Fifty patients with poststroke balance dysfunction were randomly allocated: 25 cases to the treatment group and 25 cases to the control groups. The treatment group received acupuncture at Huatuo jiaji points plus virtual balancing game-based rehabilitation training and the control group, virtual balancing game-based rehabilitation training alone. The Berg Balance Scale (BBS) score, the Timed Up and Go Test (TUGT) score, the COP offset distance indices (EO2, EC2, EOTS and EO1) and the modified Barthel Index (MBI) score were recorded in the two groups before and after treatment.Results There were statistically significant pre-/post-treatment differences in the BBS score, the TUGT score, the COP offset distance indices and the MBI score in the two groups of patients (P<0.05). There were statistically significant post-treatment differences in the BBS score, the TUGT score, the COP offset distance indices and the MBI score between the treatment and control groups (P<0.05).Conclusion Acupuncture at Huatuo jiaji points plus virtual balancing game is an effective way to treat poststroke balance dysfunction.

The biologically active constituents in Gynostemma pentaphyllum are dammarane-type glycosides,called gypenosides.They are believed to be the highest contents of this herb,easy to obtain,and mainly active in anti-tumor,controlling the blood glucose,lipid-lowering,cardiovascular protection,etc.The saponins may change into sub-glucoside after hydrolysis,for the intemal acetal glucoside structure is vulnerable to acid,alkali,and enzyme degradation.Through searching the literatures in recent years,this paper summarized the chemical constituents in the hydrolyzed products of gypenosides,for providing references to discover novel and more active lead compounds.

Objective To explore the central mechanism of acupuncture at Baihui (GV20) for memory impairment after stroke. Methods 32 stroke patients were randomized to receive acupuncture at Baihui (GV20) (as observation group) and acupuncture at Yanglingquan (GB34) (as control group) for 8 weeks. At the meantime, all participants received routine treatment including physical and occupational therapies. They were scanned with resting-state functional magnetic resonance imaging (fMRI) to find functional connectivity and assessed with Wechsler Memory Scale (WMS) before and after treatment. The results of WMS and functional connectivity were analyzed with Pearson's correlation. Results The memory scores and memory quotient improved significantly after treatment in the observation group (P<0.05). The functional connectivity significantly increased occurred in the left hippocampus to right inferior frontal gyrus, right middle frontal gyrus and left inferior frontal gyrus; and right hippocampus to left middle frontal gyrus, left superior frontal gyrus and left parietal lobe. Significant correlations were found between memory quotient and functional connectivity of hippocampus to frontal lobe and left parietal lobe in the observation group. There was no statistical significance in memory scores and memory quotient in the control group. The functional connectivity significantly decreased in left hippocampus to right middle occipital gyrus, and right hippocampus to right superior temporal gyrus and right posterior lobe of cerebellum. There was no statistical correlation between functional connectivity and results of WMS. Conclusion The acupuncture at Baihui can improves memory ability of stroke patients, which may associate with the increase of functional connectivity of hippocampus with frontal lobes and parietal lobes.

Objective To observe the effect of digital acupressure plus mechanical sputum expectoration on the rehabilitation of patients with stroke-associated pneumonia. Method Forty-six patients with stroke-associated pneumonia were randomized into a treatment group of 22 cases and a control group of 24 cases. The treatment group was intervened by digital acupressure plus mechanical sputum expectoration, while the control group was by mechanical sputum expectoration alone. The simplified version of Clinical Pulmonary Infection Score (CPIS), Fugl-Meyer assessment scale, and modified Barthel Index (BI) were adopted for evaluation before and after intervention. Result After treatment, CPIS, Fugl-Meyer and BI scores were changed significantly in both groups (P<0.01). There were significant differences in comparing the CPIS, Fugl-Meyer and BI scores between the two groups after intervention (P<0.05). After intervention, the two groups showed a negative correlation between CPIS score and Fugl-Meyer score, as well as between CPIS score and BI score. Conclusion Digital acupressure plus mechanical sputum expectoration can effectively improve the pulmonary symptoms in patients with stroke-associated pneumonia, benefiting the rehabilitation of the post-stroke patients.

Objective]To explore the metastasis regulatory of lymph node of papillary thyroid cancer and to analyze the influence factors.[Methods]Clinical data of 375 papillary thyroid cancer patients at our hospital between Jun 2011 and Sep 2015 were retrospectively reviewed and summarized the metastasis regulatory of lymph nodes and the tumor characteristics.[Results]All selected patients were diagnosed papillary thyroid cancer. The Total metastasis rate of cervical lymph node was 67.47%,the metastasis rate of region Ⅵ lymph nodes was 64.27%;the metastasis rate of region Ⅱ~Ⅴ lymph nodes was 36.53%. The metastasis rate of lymph nodes of the patients with tumor diameter over 1 cm,breaking through thyroid membrane and invading the cervical muscle were significantly increased(P < 0.05).[Conclusion]The central group lymph nodes were the most metastasis region of papillary thyroid cancer and should routinely be dissected by the first time of surgery. When the tumor diameter greater than 1 cm or cancer breakthrough thyroid membrane and/or invading the cervical muscles ,the ipsilateral lateral neck lymph nodes should be dissected at the same time.

Objective: To prepare scutellarin nanosuspension ( SCU-NS) and study the main influencing factors in the prepara-tion.

ObjectiveTo investigate the clinical efficacy of wrist-ankle acupuncture plus continuous exercise therapy for post-stroke shoulder pain.MethodsEighty patients with post-stroke shoulder pain were randomly allocated to treatment and control groups, 40 cases each. The control group received continuous exercise training with an upper limb multi-joint rehabilitation training instrument and the treatment group, wrist-ankle acupuncture in addition. The affected limb SEP N9 and N13 latency values, shoulder pain severity (the VAS score) and the upper limb motor function score were observed in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.ResultsThe total efficacy rate was 90.0% in the treatment group and 75.0% in the control group; there was a statistically significant difference between the two groups (P<0.05). There was a statistically significant pre-/post-treatment difference in SEP N9-N13 wave interval on the affected side in the two groups (P<0.01). There was a statistically significant post-treatment difference in SEP N9-N13 wave interval on the affected side between the treatment and control groups (P<0.05). There were statistically significant pre-/post-treatment differences in the VAS score and the Fugl-Meyer score in the two groups (P<0.01). There were statistically significant post-treatment differences in the VAS score and the Fugl-Meyer score between the treatment and control groups (P<0.01).ConclusionsWrist-ankle acupuncture plus continuous exercise therapy is an effective way to treat post-stroke shoulder pain.

Objective To observe the functional connectivity (FC) pattern linking the hippocampus with the rest of the brain in ischemic stroke patients with cognitive dysfunction,especially the default mode network (DMN).Methods Resting-state functional connectivity magnetic resonance imaging (fMRI) was performed on 15 ischemic stroke patients with cognitive dysfunction (the patient group) and 10 normal elderly controls.The bilateral hippocampus was the region of interest.Correlation analyses yielded a mapping of cerebral functional connectivity activation for both groups.Results Compared with the healthy controls,the patient group showed weakened functional connectivity between the hippocampus and other regions including the cingulate gyrus,the superior,middle and inferior frontal lobes,the inferior parietal lobule and the superior temporal gyrus.But there was enhanced functional connectivity with the cerebellar posterior lobe,the occipital lobe,the medial temporal lobe,the precuneus and the calcarine.The results were significantly different between the two groups.Conclusion The functional connectivity pattern of the hippocampus is impaired in stroke patients with cognitive dysfunction.Reduced functional connectivity between brain regions may be one cause of cognitive dysfunction after stroke,and enhanced functional connectivity may be an appropriate compensatory mechanism.

Objective To construct the pshuttle-Egr-1-hSmac plasmid and transfect human breast cancer MDA-MB-435 cells,and to observe its radiotherapy enhancing effect on tumor cells.Methods The empty vector pshuttle and pshuttle-Egr-1-hSmac plasmid were transfected into MDA-MB-435 cells by liposomal.At different time(4,8,12,24 and 48 h)after irradiation with 2.0 Gy X-ray and 24 h after irradiation with 0.5 -5.0 Gy,the total RNA and protein were collected and extracted from these cells to analyze the Smac mRNA and protein expression levels with RT-PCR and Western blotting methods. The cells were divided into control, pshuttle, pshuttle-Egr-1-hSmac,2.0 Gy irradiation group, pshuttle + 2.0 Gy irradiation and pshuttle-Egr-1-hSmac+2.0 Gy irradiation groups.MTT method was used to evaluate cell proliferation,and the cell survival ability was measured with clone formation assay;Annexin Ⅴ/PI double staining and PI single staining were used to examine the apoptosis and cell cycle of MDA-MB-435 cells. Results There was no Smac mRNA expression in MDA-MB-435 cells in control and pshuttle groups,but the Smac mRNA expression levels in MDA-MB-435 cells in pshuttle-Egr-1-hSmac plasmid group were gradually increased with the time prolongation, and reached the maximum at 24 and 48 h;the Smac mRNA expression levels in MDA-MB-435 cells were increased gradually 24 h after irradiation of 0.5 - 5.0 Gy X-ray with the increasing of irradiation doses, and reached the maximum after 2.0 and 5.0 Gy irradiation. The Smac protein expression levels in pshuttle-Egr-1-hSmac plasmid group were increased gradually with the time prolongation,and reached the maximum at 24 h.The Smac protein expression lervels were increased 24 h afer irradiation of 0,0.5,1.0,2.0 and 5.0 Gy X-ray,especially in 5.0 Gy group. The MTT results showed that the A490 values in 2.0 Gy,pshuttle+2.0 Gy and pshuttle-Egr-1-hSmac groups 24, 48,and 72 h after irradiation were lower than those in control group(P<0.01);the A490 values of MDA-MB-435 cells in pshuttle-Egr-1-hSmac group after 1.0-5.0 Gy X-ray irradiation were lower than those in 0 Gy group (P<0.05 or P<0.01);the survival fraction(SF)in pshuttle-Egr-1-hSmac group was lower than those in control group (P<0.01).The percentages of the cells at G0/G1 and S phase in pshuttle-Egr-1-hSmac group were lower than those in 2.0 Gy group(P<0.01),the percentage of the cells at G2/M phase was higher than that in 2.0 Gy group (P<0.01);the apoptotic rate of the cells in pshuttle-Egr-1-hSmac group was higher than that in 2.0 Gy group (P<0.01).Conclusion X-ray irradiation can significantly increase the Smac mRNA and protein expression levels in MDA-MB-435 cells transfected with pshuttle-Egr-1-hSmac plasmid,inhibit the cell survival rate,and induce G2/M arrest and apoptotic increasing;Smac gene combined with radiotherapy could significantly increase the radiosensitivity of breast cancer cells.
