Objective Pain is a prevalent and distressing symptom in patients with cancer which has a significant impact on patients’ physical health, psychological well-being, and quality of life (QOL). Deficiency of pain care, inadequate pain communication, and reluctance toward pain medication contribute to the difficulties in improving the situation of patients with cancer pain. Fortunately, the integration of self-management and professional healthcare provides new opportunities for patients with cancer pain. Methods A two-arm randomized controlled trial will be conducted to assess the effectiveness of self-management application compared with routine care among patients with cancer pain. Based on Orem's self-care theory and Naylor's transitional care theory, cancer pain self-management application “Pain-housekeeper” was developed with dual client: patient client and medical client. A total of 120 patients with cancer pain are recruited from two university-affiliated tertiary public hospitals in China. They are randomly assigned to the control group and the intervention group. The patients in the control group get routine care while the patients in the intervention group get routine care and Pain-housekeeper App. The intervention is delivered by registered doctors, nurses, and postgraduate nursing students specialized in pain care. Effect measurements for both groups are carried out with questionnaires at baseline (T0), after 4 weeks (T1) and after 12 weeks (T2). The primary outcomes include pain condition, self-efficacy, and QOL. The secondary outcomes include pain medication adherence, satisfaction, anxiety, and depression. Compliance of data submission, economic evaluation, usage, and clinical data are also considered in the test. Data for the evaluation are gathered continuously during the study period. Discussion This article provides insight into the effectiveness of a theory-based self-management mobile application intervention delivered to patients with uncontrolled cancer pain. The results are used to help patients to improve cancer pain control, self-efficacy, and QOL. Conclusions The findings of this article provide evidence to support the implementation of an innovative and easily accessible intervention that enhances health outcomes.

Bemisia tabaci is an important agricultural pest with worldwide distribution and host preference. Therefore, understanding the biology of this pest is important to devise specific pest control strategies. The antennae of herbivorous insects play an important role in the identification of hosts using plant volatiles. To understand the features of antennae in B. tabaci MEAM 1(formerly known as biotype ‘B’) and MED (formerly known as biotype ‘Q’), the morphology and distribution of the antennal sensilla were examined using scanning electron micrographs. The results showed that the average antennae length in MEAM 1 was longer than MED. No differences were observed in the number and distribution of antennal sensilla in MEAM 1 and MED antennae; each antenna had nine different types of sensilla. Both cryptic species possessed Microtrichia, Grooved surface trichodea sensilla, Chaetae sensilla, Coeloconic sensillaⅠandⅡ, Basiconic sensilla Ⅰ, Ⅱ and Ⅲ and Finger-like sensilla. This is the first report of Grooved surface trichodea sensilla and Basiconic sensilla Ⅱ on B. tabaci flies. The numbers of Chaetae sensilla were different in the females and males of MEAM 1 and MED, which females having 5 and males containing 7. The surface structure of Basiconic sensilla Ⅰ was different with MEAM 1 showing a multiple-pitted linen surface and MED showing a multiple-pitted pocking surface. Basiconic sensillaⅡ were double in one socket with the longer one having a multiple-pitted surface and the shorter one with a smooth surface. Basiconic Ⅲ and Finger-like sensillae were longer in MEAM 1 antennae than in MED antennae. Our results are expected to further the studies that link morphological characteristics to insect behavior and help devise strategies to control insect pests.

Polyacrylamide gel (PAAG) has been used as a soft tissue filler material for cosmetic purposes in Europe and China since 1997. The various complications of PAAG have been reported. A total of 15 patients who received PAAG injections at other institutions were treated for gel migration in the authors' hospitals. During treatment, the authors found that the injected PAAG had not formed capsules within the muscle and was encapsulated only by thin fibrous tissue in skin and mammary glands. Consequently, the filler material migrated easily because of muscular activity or the influence of gravity, especially when the capsule was broken by incorrect massage or incidental force. It is suggested that PAAG should not be injected into muscular tissue or subcutaneous areas with active movement, such as joints and muscles involved in facial expression with thin skin. After years of gel implantation, the thinned capsule may result in an increasing incidence of this complication. Management and some clinical findings in relation to the complication also are discussed.

Quantitative characterization of skin collagen on photo-thermal response and its regeneration process is an important but difficult task. In this study, morphology and spectrum characteristics of collagen during photo-thermal response and its light-induced remodeling process were obtained by second-harmonic generation microscope in vivo. The texture feature of collagen orientation index and fractal dimension was extracted by image processing. The aim of this study is to detect the information hidden in skin texture during the process of photo-thermal response and its regeneration. The quantitative relations between injured collagen and texture feature were established for further analysis of the injured characteristics. Our results show that it is feasible to determine the main impacts of phototherapy on the skin. It is important to understand the process of collagen remodeling after photo-thermal injuries from texture feature.

A high precision 2-D laser measuring instrument is designed to meet the needs of high precision measurement. Through the error analysis of the measuring system, the geometrical errors show certain stability in the results. Geometrical correction methods are intensively researched. The angle between two axes of the measured plate and axes of the instrument produces deviations of coordinates X and Y of the points on the plate. Different coordinate systems are not roughly aligned. An inclined correction model is proposed to compensate the deviations and transform the coordinate systems. Then the perpendicular compensation model is proposed using the least square approximation method and the relationship between the coordinates X and Y. To reduce the effect of random error and other geometrical errors, a multi-position correction algorithm is presented through two different measuring positions. The measurement results verify that these methods and models are accurate and feasible.

Late hematoma or seroma and galactocele caused by augmentation mammaplasty have been reported in patients with silicon breast prostheses but are extremely rare in patients injected with polyacrylamide gel (PAAG). In a retrospective survey, the incidence, clinical manifestations, and management of late hematoma, seroma, and galactocele in 28 of 2,610 patients who underwent breast augmentation with PAAG injection were investigated, and 5 typical cases are presented. The diagnostic and managing methods for this complication have been assessed. The incidence of late hematoma or seroma was 0.65% and that of galactocele was 0.35% among patients with PAAG-injected breast augmentations. The clinical onsets of such late PAAG complications were of two types: rapid enlargement in 17 patients and progressive expansion in another 11 patients. Aspiration, ultrasound, and magnetic resonance imaging (MRI) are useful and sensitive tools for diagnosis. Foreign body reaction, PAAG-related tissue necrosis and fibrosis, and granuloma were shown, and the bacterial cultures in all 12 cases were negative. Needle aspiration with pressure dressing has been advocated as a reliable method for small diseases, and surgical exploration with irrigation-vacuum drainage and evacuation with capsulectomy have been considered more effective for recurrent, large, and long-term cases. In conclusion, these late complications rarely present after large-volume injections of PAAG for breast augmentation. The PAAG-related pathologic inflammatory tissue changes are suggested as the pathogenesis for the complication. Trauma and breastfeeding are considered to be stimulating factors.

Objective To explore the effects of obstructive sleep apnea syndrome (OSAS) on children's growth by the study of identical twins. Study design Seventeen cases of nonobese children with OSAS were included in this study. The control group was their identical twin sibling, who had no signs of OSAS. Data including height, weight, and serum insulin–like growth factor 1 levels were analyzed before tonsillectomy and adenoidectomy (T&A) and at 3, 6, and 12 months after surgery. Results The mean apnea hyponea index was 3.9 times/hour in patients with OSAS and became normal after surgery. Minimum oxygen saturation gradually increased after T&A. The height and weight of the OSAS group before T&A was lower than the control group. During the follow-up period, height and weight increased but were lower than the control group. Serum insulin–like growth factor 1 levels in the OSAS group before T&A were lower than the control group. The level was significantly increased 3 months after T&A. Conclusion OSAS impairs growth and development. Significant growth recovery occurs after T&A, and early surgical intervention is an important factor for improvement in growth.

Since 1997, the hydrophilic polyacrylamide gel (PAAG), an injectable alloplastic biomaterial, imported from the Ukraine has been used for augmentation mammaplasty in China. There were twelve patients with various complications visiting our hospitals after breast augmentation with injected hydrophilic polyacrylamide gel by other clinics, even though such procedures are not performed in our clinical practices. The complications included four cases of PAAG-induced multiple induration and lumps, and one with lactation, three cases of hematoma, two cases of inflammation (infection), and persistent mastodymia, unsatisfactory contour results and abnormal skin sensations in each case. All patients have been treated by removing the injected gel and giving antibiotics. Other procedures included replacement by silicon breast prostheses, mammotomy, and segmental mastectomy. We suggest that the injectable hydrophilic polyacrylamide gel be contraindications for breast augmentation in any young female who is not married, or without a child, with a tendency to hemorrhage, and with little mammary tissue. Some considerations to prevent and manage these complications are discussed.
