Chinese Acupuncture & Moxibustion,Vol 36,No. 09
Objective To compare the clinical efficacy differences between relaxing needling combined with rehabilitation training and rehabilitation training alone for medial collateral ligament (MCL) injury of knee joint. Methods Sixty cases of MCL injury were randomly assigned into an observation group (30 cases, one case dropping out) and a control group (30 cases, two cases dropping out). Patients in the control group were treated with rehabilitation training; based on the treatment of control group, patients in the observation group were additionally treated with relaxing needles at Ashi points, Heding (EX-LE2), Neixiyan (EX-LE4), Dubi (ST35), Yanglingquan (GB34), Liangqiu (ST34), etc. The treatment was given once a day; six treatments were taken as one course, and totally four courses were given. The visual analogue scale (VAS), Lysholm knee function score and clinical efficacy before and after treatment were evaluated; also the safety was evaluated. Results After treatment, VAS scores were apparently reduced and the Lysholm scores were obviously increased in the two groups (all P < 0.001). The improvement of VAS and Lysholm scores in the observation group were superior to that in the control group (both P < 0.05). The effective rate was 93.1% (27/29) in the observation group, which was superior to 71.4% (20/28) in the control group ( P < 0.05). During the treatment, no adverse events occurred in the two groups. Conclusion Relaxing needling combined with rehabilitation training can effectively improve the swelling, pain and other symptoms of MCL injury, which is superior to rehabilitation training alone.

This article uses data from China Family Panel Studies from 2010 to 2014 to empirically examine the impact of the new rural cooperative medical system (NCMS) on farmers’ risk-taking. It verifies whether the NCMS can increase farmers’ incomes, and whether their risk-taking is a main mechanism through which the NCMS can increase farmers’ incomes. The empirical results show that the NCMS has significantly increased the non-agricultural and agricultural risk-taking of farmers. After distinguishing the forms of non-agricultural risk taking, it is found that the NCMS has significantly promoted farmers to engage in self-employment and has no significant impact on their holdings of risky financial assets. Family heterogeneity tests find that the NCMS has a greater impact on families with a high initial wealth level and whose heads are older. Further tests show that the NCMS has significantly improved farmers’ incomes. Mechanism test finds that non-agricultural risk-taking is a main mechanism for the NCMS to increase farmers’ incomes.

The emission of SO x from marine vessels has caused serious environmental problem. Membrane contactor that offers several advantages over conventional tower device such as a compact size, operational flexibility, independent gas and liquid flow, easy scale-up, and modularity is an alternative technology in the application of marine exhaust gas desulfurization. In this work, a single ceramic tubule-based membrane contactor was fabricated from ZrO 2 ceramic membrane with average pore size of 200 nm. A series of experiments of SO 2 absorption were carried out using water as low-cost absorbent. The mass transfer performance of the unmodified and modified membrane was compared and the effects of gas flow rate, absorbent flow rate, feed gas concentration, temperature of absorbent on SO 2 removal efficiency and mass transfer rate were investigated. The long-term stability of ceramic membrane contactor was tested as well. It was found that the overall structures and the surface porosity of ceramic membrane hardly changed by surface modification with hexadecyltrimethoxysilane (HDTMS). The hydrophobic ceramic membrane with contact angle of 132° had higher desulfurization efficiency and overall mass transfer coefficient than the unmodified membrane under the same operating conditions. The desulfurization efficiency and mass transfer rate increased as the liquid flow rate increased. The desulfurization efficiency decreased as the gas flow rate and feed gas concentration increased while the mass transfer rate increased. Absorbent with low temperature was more favorable for the absorption of SO 2. CO 2 in the feed gas had little effect on the SO 2 removal efficiency. The ceramic membrane contactor had lower height of transfer unit (HTU) value than conventional packed tower and showed great potential in the application of exhaust gas desulfurization.

Escape from anti-tumor immunity is critical for tumor survival and progression. Tumor cells can suppress the anti-tumor immune response via recruitment of various immune cell populations or expression of inhibitory molecular factors. Esophageal cancer is a deadly disease, ranking the sixth among all cancers in mortality. Despite advances in diagnosis and therapy, the prognosis of esophageal cancer is still poor. Investigation of the immune escape mechanism can provide new insights for the treatment of esophageal cancer. This article provides an overview of the mechanism of tumor immune escape as well as research progress in esophageal cancer.

The Model of Multiple Identity Tracking (MOMIT) proposed by Oksama and Hyönä (2008) models observers’ tracking performance among multiple unique moving items. The model provides a functional explanation for the process for how the “what” and “where” information work together in a dynamic visual environment. However, two main issues in MOMIT are still unclear. First, though MOMIT supposes that the “what” and “where” information can be analyzed separately by the identity processing system and location processing system in the early stage, it is unclear whether these two processing systems share the same attentional resources. Second, MOMIT posits that the what-where bindings are stored in the temporary episodic buffer, but there is no direct evidence of this. Exploring these two issues may help us understand the cognitive mechanism of multiple identity tracking (MIT) better and improve the MOMIT. In this study, we used a variant of the MIT paradigm in which we interfered with the what-where binding by making the objects switch identities during tracking. In Experiment 1, we designated three identity-switch conditions: identity switch within the set of targets, identity switch within the set of distractors, and identity switch within all objects. And in the baseline condition the objects’ identities did not change throughout tracking. Given the limitation of the whole report method, Experiment 2 then tested the hypothesis again using the partial report method. The numbers of 0–9 were used as the objects’ identities in both experiments. The results of Experiment 1 showed that identity switching impaired both location tracking and identity recognition. Specifically, the location tracking and identity recognition was impaired the most in the condition where identities switched for all objects, followed by the condition in which the identities of the targets switched, and then the condition in which the identities of the distractors switched, which was not significantly different from the baseline condition. In addition, this declining trend was the same when participants had to track 4 targets and 5 targets. In other words, the increase of tracking load diminished people’s capacity to track location and identity recognition. The results of Experiment 2 showed the same effect due of interfering with what-where bindings. We also found that the partial report method revealed more data than the whole report method. Finally, in Experiment 3, we completely randomized pronunciations of the letters A-Z in the auditory channel in order to eliminate the interference of phonetic rehearsal. The results were the same as in Experiment 1. That is, the phonetic rehearsal did not affect the effects of identity-location binding. Overall, the results provide deeper understanding of MIT and improve the MOMIT through direct behavioral evidence. (1) The results reveal that the location processing system and identity processing system share a common attention resource pool, and the utilization of “where” information in the visual system seems to take precedence over “what” information. (2) The impairment of what-where binding will damage the tracking performance of MIT. (3) People mainly use attentional resources to enhance visual resolution towards targets (target-oriented) in MIT, rather than processing distractors. (4) The whole report method is less sensitive than the partial report method and may underestimate the capacity of visual working memory. (5) Even after controlling for phonetic rehearsal, people still experience interference from identity-location binding when they are tracking multiple moving objects.
