Acupoint is the initial response site of acupuncture stimulus and also the source link of the effect onset of acupuncture. Acupuncture is a mechanical physical stimulus. How is the mechanical force of acupuncture transduced into neuroelectrical and biochemical signals at acupoint? How does the physiochemical information of acupoint launch acupuncture effect? All of these remain the common and crucial questions in the study of acupuncture effect mechanism. Physical changes are induced in the local tissue of acupoint by needling techniques, such as the deformation and displacement of muscle fibers, which may act on the nerve ending receptors and produce electroneurographic signals. Besides, these changes may activate the mechanosensitive ion channels of the cytomembrane in acupoint site. Through cellular signal transduction, the physical signals may be transformed into chemical ones to trigger the physiochemical coupling response of acupoint microenvironment. Eventually, acupuncture effect is generated via nerves and body fluids. "The mechanical force of acupuncture", through "the physiochemical transduction", promotes the body's perception and transmits acupuncture signals. It suggests that acupoint is the "transducer" in the physiochemical information coupling response of acupuncture.穴位是针刺刺激的初始应答部位，也是针刺起效的源头环节。针刺作为一种机械性物理刺激，其机械力在穴位如何转导为神经电信号和生物化学信号，穴位局部的理化信号如何启动针刺效应，是针刺作用原理研究中的共性、关键性源头问题。针刺手法引起穴位局部组织物理变化，如肌纤维的形变位移等，可作用于神经末梢感受器，产生神经电信号；也可激活穴区细胞膜上的机械敏感性离子通道，经细胞信号转导将物理信号转化为化学信号，触发穴位微环境理化耦合应答，通过神经和体液途径产生针刺效应。“针刺机械力”在穴位局部通过“理化换能”，促进机体感知并传递针刺信号，表明穴位是针刺物理化学信息耦合应答的“换能器”。.

To investigate the long-term effects of residual bone height (RBH), maxillary sinus membrane perforation, and cavities on survival of implants with lateral maxillary sinus lifting (MSFA).Fifty-six patients (98 implants) who underwent MSFA from 2005 to 2009 and followed up till 2019 were enrolled. RBH was assessed using a series of panoramic and periapical X-ray films. Based on the presence of RBH, sinus membrane perforation, cavities, the cumulative survival rate (CSR) were evaluated using log-rank test and risk ratio of implant failure, SPSS 21.0 software package was used to analyze the data.The residual bone height of implants with sinus membrane perforation was significantly larger than those without sinus membrane perforation. The residual bone height of the survival implants was significantly larger than that of the failed implants(P0.05), but there was no significant difference in the residual bone height between gender, smoking and cavities(P0.05). The total CSR of 10 years after implantation by MSFA was 94.5%, of which the females was significantly higher than that of males, non-smokers was significantly higher than that of smokers, and RBH≥3 mm was significantly higher than that of RBH3 mm(P0.05). However, there was no significant difference in CSR between sinus membrane perforation and non-sinus membrane perforation.Implants with RBH3 mm have lower CSR, and the survival is acceptable under proper oral hygiene maintenance conditions. Sinus perforation and cavity do not affect the survival of lateral MSFA implants.

In this paper, we proposed a semi-supervised learning approach to deal with the task of high dimensional Android malware classification. Our approach includes a random projection method for reducing feature dimensionality which would be more efficient than usual feature selection methods in existing work for the task. We also introduced a new method of SGD-based SVM with adapted sampling, which was based on the insight from the confidence and nearest neighbor clustering analysis of input data. The approach was tested on a real-world competition dataset, and effectiveness of the new method was verified by experimental results. By using the new method, we can even obtain a better classification accuracy than the best score produced in the competition.

BACKGROUND Wound dressings are divided into traditional and new types. The new dressings are thought to accelerate wound healing. The purpose of this study was to supplement the scanty data on the absorbency of the new dressings and their effects on evaporation from the burn surface. METHODS The water absorption rate of four dressings (carbon fiber dressing, hydrogel dressing, silver nanoparticle dressing, and vaseline gauze) were measured by the immersion-weight gain method. A total of 120 inpatients with 10% superficial partial-thickness burn wounds were randomly assigned to four groups, each with 30 participants. Carbon fiber dressing, hydrogel dressing, and silver nanoparticle dressing were used in groups A, B, and C as the primary dressing, and traditional vaseline gauze was used in group D as the control. Multi-spot evaporation from normal skin and naked wound, and from wounds covered with each of the four dressings was measured post-burn on days 1, 3, 5, and 7 by an EP-I evaporimeter under conditions of 21 degrees C - 22 degrees C ambient temperature and 74% - 78% humidity. RESULTS The absorption rates of the four dressings were 988% with carbon fiber dressing, 96% with silver nanoparticle, 41% with vaseline gauze, and 6% with hydrogel. Evaporation from the naked burn wounds was about 1/3 higher than from normal skin (P < 0.01). Compared with wounds without applied dressing, evaporation from dressed wounds decreased and was time-dependent (P < 0.01). The evaporation of wounds with carbon fiber dressing was the lowest ((13.40 +/- 2.82) mlxh(-1)xm(-2), P < 0.01) on day 1 post-burn, compared with the other groups. CONCLUSION All four dressings have water retention capacity while carbon fiber dressing has the highest absorption rate and shows the best containment and evaporation from the burn wound.

This paper develops a new Early Warning System (EWS) model for evaluating the identifying risk of listed companies' merger and acquisition, based on a fuzzy comprehensive evaluation method. The evaluation on the performance of the identifying risk of listed companies' merger and acquisition depends on more comprehensive analysis than economic evaluation. This paper introduces a fuzzy comprehensive evaluation method, analyzes the performance of the identifying risk, constructs a fuzzy comprehensive evaluation form, and establishes a two level fuzzy comprehensive evaluation method for evaluating the performance of the identifying risk of listed companies' merger and acquisition.

This article aims to construct a risk model for the prediction of foot-and-mouth disease (FMD) entrance caused by passengers who illegally carry meat products of cloven-hoofed animals through international airports into a country. The risk that meat contaminated with the FMD virus is formulated as the probabilities of FMD factor events (the prevalence of FMD), the commodity factor event (the transportation, storage, and distribution (TSD) factor event), and the passenger event. Data used for analysis were records of illegal meat product carriers from areas A and B intercepted at an international airport in Taiwan. A risk model was proposed to simulate the probability distributions in disease prevalence, probability of FMD virus existing in the meat products after meat processing, and estimation of survival of virus and time period for TSD. The probability of the passenger event was hypothesized with the odds of intercepted passengers and estimated via logistic regression. The results showed that the odds of passengers being intercepted by beagles were higher than those intercepted by Customs. By conducting Monte Carlo simulations, the probability of FMD virus risk caused by FMD factors from area A was 149 times lower than that from area B. The probability of FMD virus risk caused by the passenger event from area A was four times lower than the corresponding probability from area B. The model provides a contribution to FMD prevention and can be a reference for developing models of other diseases.

To explore the influence of silver nanoparticle dressing on prevention of infection and healing of the second degree burn wound.One hundred and ninety-one burn patients with second degree including superficial and deep burn wound were randomly divided into three groups. Group A including 65 cases was treated by silver nanoparticle dressing on wounds, and group B (63 cases) and group C (63 cases) were treated by 1% silver sulfadiazine cream and vaseline gauze on their wounds, respectively. Dressing was changed daily, and wound swab bacterial cultures were performed before and after dressing change, and also wound healing times were recorded in each patient.Group A and B were similar in their bacterium colonizations on wound after treatment with the silver nanoparticle dressing and 1% silver sulfadiazine cream, and they had a similar effect on reducing bacterium colonization on wound after treatment, while in vaseline gauze group bacterium colonization on wound increased after treatment. In group A the wound healing time of superficial second degree was significantly shorter than those in group B and group C (P0.01). In deep second degree wounds the healing time in group A was much shorter than that in group C (P0.01), but had no significant difference when compared with group B (P0.05).Silver nanoparticle dressing can be used on second degree burn wound and can decrease the risk of wound infection and accelerate wound healing.
