Objective To observe the effect of Tung’s acupuncture on walk and balance function in patients with Parkinson’s disease (PD). Method Ninety-two eligible PD patients were randomized into a control group and a treatment group, 46 cases in each group. The control group was intervened by Levodopa, while the treatment group was additionally intervened by Tung’s acupuncture. The two groups were both treated for 20 d. Before and after the treatment, the walk and balance function were evaluated by the indices of NeuroCom Balance Master, including Walk Across (WLK), Step/Quick Turn (SNT), and Timed Up & Go Test (TUGT), and the results were compared between the two groups. Result The walk speed, step length, swing in turning, time-consumption in turning, and TUGT were improved after the intervention in both groups (P<0.05), and the improvements in the treatment group were more significant than that in the control group (P<0.05). Conclusion Tung’s acupuncture plus oral administration of Levodopa can markedly improve the walk and balance function in patients with PD.

Objective To explore the effects of H 2 S on neuronal injuries induced by oxygen glucose deprivation /reoxygenation ( OGD/R) in cortical neurons .Methods For OGD, the primary cultured cortical neurons were incubated with glucose-free EBSS media for 4h in N2/CO2/O2 (93%/5%/2%) atmosphere.Thereafter, the media were replaced by Neurobasal/B27 culture media and the neurons were incubated for 12 h in a 5%CO2 incubator at 37℃.NaHS was used as a H2S donor and cell survival rate was determined by cell counting kit 8(CCk-8).[Ca2+]i was determined using fura-2/AM and fluorescence microscopic imaging systems .The release rate of lactate dehydrogenase ( LDH) was determined by lactate dehydrogenase assay kit , and cell damage was analyzed by staining of propidium iodide ( PI ) .Results After pretreated with 200, 300 and 600μmol/L sodium hydrosulfide ( NaHS) for 30min before OGD/R, the cell survival rate of neurons significantly increased (n=4).[Ca2+]I(n=5), LDH release rate (n=4) and cell damage percentage (n=6) in the neuron pretreated with 300 μM NaHS were significantly lower than those in ODG/R cells.Treatment with 10μmol/L calcium chelator BAPTA also reduced the LDH release rate and cell damage percentage induced by ODG /R in neurons . Conclusion The results indicate that H 2 S may inhibit the OGD/R induced damage in cortical neurons via reducing calcium overload of neurons .

Objective To evaluate the efficacy and safety of consolidation chemotherapy after thoracic radical concurrent chemoradiotherapy for patients with oligometastatic non?small cell lung cancer ( NSCLC) . Methods Sixty?six NSCLC patients with more than five metastases from 2008 to 2013 were enrolled, and image?guided radiotherapy with conventionally fractionated or hypofractionated doses were performed for these patients. Platinum?based doublets chemotherapy was applied for both concurrent chemoradiotherapy and consolidation chemotherapy. Short?term outcome, adverse reactions, and survival rate were assessed for the patients after treatment. Results Sixty?four patients completed the treatment. The median biologically equivalent dose for planning target volume of thoracic primary tumor lesions was 72 Gy, with a median number of chemotherapy cycles of 4. The objective response rate for thoracic lesions was 70%. The follow?up rate was 97%. The 1?, 2?, and 3?year overall survival ( OS) rates were 72%, 53%, and 31%, respectively, with a median OS time of 25 months;the 1?, 2?, and 3?year progression?free survival ( PFS) rates were 56%, 26%, and 7%, respectively, with a median PFS time of 14 months. The incidence of grade 2?3 acute radiation pneumonitis and radiation esophagitis was 1% and 17%, respectively, and the incidence of grade 3?4 decreases in leukocytes, hemoglobin, and platelet count was 39%, 11%, and 16%, respectively. Conclusions Radical radiotherapy combined with concurrent and consolidation chemotherapy for oligometastatic NSCLC can achieve good short?term outcome and long?term survival, with tolerable adverse effects.

Objective To observe the clinical efficacy of extracorporeal shock wave (ESW) plus electroacupuncture in treating periarthritis of shoulder.Method Ninety patients with periarthritis of shoulder were randomized into an electroacupuncture (EA) group, an ESW group, and an ESW plus EA group, 30 cases in each group. The EA group was intervened by EA, the ESW group was treated with ESW, and the ESW plus EA group by ESW and EA. The three groups were treated once every 2 d, with successive 10 sessions as a treatment course. The Visual Analogue Scale (VAS) score and shoulder range of motion (ROM) score were evaluated before and after the treatment in the three groups. Result The VAS scores dropped significantly in the three groups after the intervention (P<0.05); there was no significant difference in comparing the VAS score between the EA group and ESW group after the intervention (P>0.05); the VAS score in the ESW plus EA group was significantly different from that in the EA group and ESW group after the treatment (P<0.05). The ROM scores were significantly improved in the three groups after the intervention (P<0.05); there was no significant difference in comparing the ROM score between the EA group and the ESW group after the intervention (P>0.05); the ROM score in the ESW plus EA group was significant different from that in the other two groups (P<0.05).Conclusion ESW plus EA can more significantly ease the pain and improve the shoulder ROM in treating periarthritis of shoulder compared with the two methods used separately.

Objective To study the effect of Botulinum toxin type A (BTX-A) on lower limbs spasticity after stroke. Methods 109 convalescent patients after stroke were randomly divided into treatment group and the control group.

Objective:To observe the activation of cerebral regions during swallowing by magnetoencephalography (MEG), and discuss the temporal and spatial characteristics of neural circuit.Methods:Ten healthy subjects were selected, and the magnetic signals of their brains were recorded using 148 channel full head type MEG system in the magnetic shielding room.Data were analyzed using CURRY8 analysis software and the localization algorithm was based on minimum modulus low resolution electromagnetic imaging method (LORETA). Every 300 ms data were set as an independent analysis stage and made the highest position of the cerebral cortex F-distribution values (F-distributed) as the activation area.The activation areas were analyzed during swallowing through time and space location.Results:Paracentral lobule, anterior central gyrus, medulla oblata, posterior central gyrus, inferior frontal gyrus, parietal lobules, angular gyrus, corpus callosum, middle frontal gyrus, cingulate gyrus, orbital gyrus, thalamus, bottom of third ventricle, corona radiata, precuneus, frontal insula, cerebellopontine angle, superior frontal gyrus and basal ganglia area were activated during swallowing, in which the top eight brain regions were paracentral lobule, anterior central gyrus, corpus callosum, posterior central gyrus, superior parietal lobule, middle frontal gyrus, cingulate gyrus, and basal ganglia.When the 10 subjects performed the deglutition, MEG signals of 8 subjects were mainly activated by the left cerebral hemisphere at 0-300 ms, the bilateral cerebral hemisphere or intermediate region at 301-600 ms, and the right cerebral hemisphere at 601-900 ms.MEG signal of 1 subject was activated by the right cerebral hemisphere at 0-300 ms, and the left cerebral hemisphere at 301-600 ms and 601-900 ms.MEG signal of 1 subject was mainly activated by the right cerebral hemisphere at 0-300 ms and 601-900 ms, and in the intermediate region at 301-600 ms.Conclusion:During swallowing the MEG signals appeared left laterality in the early stage and right laterality in the later stage, and showed a close correlation with time.There may be a swallowing neural circuit composed by the central region, corpus callosum, superior parietal lobule, middle frontal gyrus, cingulate gyrus and basal ganglia, in which the central region is the core.

With the aging of population, the elderly (≥65 years old) cancer patients have become one of the main populations for cancer care. For inoperable locally advanced head and neck squamous carcinomas, cisplatin-based concurrent chemoradiotherapy is the first-line choice. Several large clinical studies have shown that patients under 70 years of age can still benefit from concurrent chemoradiotherapy, while it should be cautious to apply chemotherapy to patients aged 70-80 years. For elderly patients who are intolerant to cisplatin, carboplatin or other regimens with less gastrointestinal and renal toxicity should be considered. Although anti-epidermal growth factor receptor (EGFR) monoclonal antibodies combined with radiotherapy has been proved to be more effective than radiotherapy alone in total patient population, age-subgroup analysis showed limited benefit in elderly patients. The safety of immune checkpoint inhibitors in elderly patients has been validated and those with high programmed death ligand-1 (PD-L1) expression may benefit from concurrent or neoadjuvant immunotherapy, however, high-level evidence is still lacking. For patients older than 80 years, radiotherapy alone may be superior to concurrent chemoradiotherapy, and hypofractionated radiotherapy for palliative purposes can be safely used in this population.

Objective:To explore an implementation method and results of an inverse dose optimization algorithm (gradient-based planning optimization, GBPO) in three-dimensional brachytherapy.Methods:A standard quadratic objective function was used in the GBPO. The optimization code of GBPO was performed based on LBFGS (Limited memory Broyden Fletcher Goldberg Shanno). Seven cervical cancer patients using different applicators and 15 cervical cancer patients using the Fletcher applicator (Nucletron part#189.730) were retrospectively analyzed. The plan quality of GBPO was firstly assessed by isodose lines, then dose-volume histogram (DVH) parameters of CTV(D 100%, V 150%) and organs at risk(D 0.1cm 3, D 1.0cm 3, D 2.0cm 3) were used to evaluate the difference among the GBPO, IPSA and Graphic plans. Results:For the 7 patients using different applicators, GBPO could optimize the conformal dose distribution, and the DVH parameters of the target and organs at risk were basically the same among the GBPO, IPSA and Graphic plans. For 15 patients using the Fletcher applicator, the difference in DVH parameters between the GBPO and IPSA plans was not statistically significant. There was no remarkable difference in the DVH parameters between the GBPO and Graphic plans, but the D 100% of the GBPO plan was significantly higher ( P<0.01), and the V 150% was significantly lower ( P<0.01) than that of the Graphic plan. Conclusions:The quality of the GBPO plan is similar to that of the IPSA plan in terms of target coverage and organ protection. The inverse dose optimization algorithm GBPO can be integrated into a three-dimensional brachytherapy treatment planning system.
