Mobile Health System for Meeting Health Information Needs in Patients With Head and Neck Cancer Undergoing Radiotherapy: Development and Feasibility Study.

Patients with head and neck cancer undergoing radiotherapy encounter physical and psychosocial challenges, indicating unmet needs. Mobile health technology can potentially support patients. This single-armed feasibility study included 30 patients with head and neck cancer undergoing radiotherapy. Patients were asked to use the Health Enjoy System, a mobile health support system that provides a disease-related resource for 1 week. We assessed the usability of the system and its limited efficacy in meeting patients' health information needs. The result showed that the system was well received by patients and effectively met their health information needs. They also reported free comments on the system's content, backend maintenance, and user engagement. This study supplies a foundation for further research to explore the potential benefits of the Health Enjoy System in supporting patients with head and neck cancer.

Efficacy and Safety of Intralesional Triamcinolone Versus Combination of Triamcinolone with 5-Fluorouracil in the Treatment of Keloids and Hypertrophic Scars: A Systematic Review and Meta-analysis.

BACKGROUND: Although keloids and hypertrophic scars are common benign hyperproliferative growths of dermal fibroblasts, the clinical problems including physical and psychological problems are significant and impairing, with few proven treatments. Intralesional triamcinolone acetonide (TAC) and combination of TAC with 5-fluorouracil (5-FU) are widely used to treat keloids and hypertrophic scars, but their efficacy and safety remain controversial. METHODS: We systematically searched MEDLINE, EMBASE, Cochrane Library, and CNKI for relevant trials. RESULTS: The mean scar height and the erythema score in the TAC + 5-FU group were lower than those in the TAC group after treatment (P < 0.05). The effectiveness based on observer assessment after treatment in the TAC + 5-FU group was superior than that in the TAC group (P < 0.05); further, the subgroup analysis showed the TAC + 5-FU group was also superior than the TAC group in the treatment of hypertrophic scars (P = 0.01), and there were no significant differences in the treatment of keloid (P = 0.12). The effectiveness based on patient self-assessment after treatment in the TAC + 5-FU group was also superior than the TAC group (P < 0.05). The overall complication rate in the TAC + 5-FU group was lower than the TAC group (P < 0.05). CONCLUSIONS: Combination of TAC with 5-FU is more effective and safer than TAC alone therapy in the treatment of keloids and hypertrophic scars. Data on keloids alone or hypertrophic scars alone are, however, limited. A better understanding of effective after intralesional combination of TAC with 5-FU in the treatment of keloids alone or hypertrophic scars alone is imperative.

The Safety and Efficacy of Intralesional Verapamil Versus Intralesional Triamcinolone Acetonide for Keloids and Hypertrophic Scars: A Systematic Review and Meta-analysis.

BACKGROUND: Keloids and hypertrophic scars often result after skin trauma. Currently, intralesional triamcinolone acetonide (TAC) is the criterion standard in nonsurgical management of keloids and hypertrophic scars. Intralesional verapamil may be an effective alternative modality, but it has been insufficiently studied. Accordingly, the study authors conducted a systematic review and meta-analysis of randomized controlled trials to compare the efficacy and safety of the two drugs. METHODS: The study authors systematically searched the MEDLINE, EMBASE, Cochrane Library, and China National Knowledge Infrastructure databases for relevant trials published in any language through September 2018. RESULTS: According to the four studies included in this review, TAC improved scar pliability and vascularity more than verapamil after 3 weeks (P < .05). For scar height and scar pigmentation, no statistical difference was observed between the treatments (P > .05). The difference in effects on symptoms was not statistically significant (P = .89). For pain and telangiectasia, no statistical difference was observed (P > .05). Verapamil resulted in fewer cases of skin atrophy (P < .05). CONCLUSIONS: It appears that TAC is more effective than verapamil for improving scar pliability and vascularity in keloids and hypertrophic scars after 3 weeks of treatment. However, verapamil has fewer adverse drug reactions than TAC, which allows for a longer treatment period and the possibility that it might be effective for patients who cannot receive TAC.

Sinus Wounds Management.

With aging populations and the increased incidence of cerebrovascular disease, diabetes, and other diseases, more and more patients suffer from pressure injuries. Pressure injuries are often difficult to heal because of the presence of sinus tracts, which make it difficult to clean and change dressings. Sinus wounds are common in patients with pressure injuries, but also occur after abdominal wall incision and in patients who have experienced a physical trauma that created a wound. It is difficult for clinicians to observe, evaluate, and repair sinus wounds because of the small surface defect and large and deep basement of each wound. This article reviews existing assessment methods and treatments for sinus wounds and proposes a new evaluation method and treatment (three-dimensional reconstruction and endoscopic techniques) to further improve treatment and provide better quality of care for patients with this type of wound.

Bisphosphonate- and disumab-related gingival disorders: case analysis from the U.S. Food and Drug Administration Adverse Event Reporting System.

Prior research has indicated that bisphosphonates (BPs) can improve periodontal disease because of their anti-osteoporosis properties. In vitro studies have shown that BPs induce cytotoxicity, inhibit wound healing, and thus affect periodontal disease. Denosumab and BPs have alternative indications. BP and denosumab are not known to correlate with gingival disorders. We assessed such a relationship by applying Bayesian and nonproportional analyses to data in the US FDA Adverse Event Reporting System (FAERS) database. The study analyzed BPs and denosumab-reported incidents with preferred terms found in the narrow Standardized MedDRA Queries for gingival disorders. A total of 5863 reported cases of gingival disorders were associated with five BPs (alendronate, pamidronate, ibandronate, risedronate, and zoledronate) and denosumab. More than 15% of patients with gingival disorders related to BPs and denosumab other than denosumab were hospitalized over short- or long-term periods. Our findings indicated BPs and denosumab had significant reporting odds ratios (ROR), proportional reporting ratios (PRR), and information components (IC) with respect to gingival disorders. Pamidronate had the highest association (ROR = 64.58, PRR = 57.99, IC = 5.71), while the weakest association was found with denosumab (ROR = 3.61, PRR = 3.60, IC = 1.77). Significant associations were found between the six drugs and gingival pain, gingival recession, gingivitis, periodontal disease, and periodontitis. In conclusion, our comprehensive overview of the correlations, clinical characteristics, and prognoses of BPs and denosumab-related gingival disorders suggests that these issues deserve continued surveillance and appropriate management.

Effects of Fu's subcutaneous needling on clinical efficacy and psychological cognitive characteristics in patients with chronic non-specific low back pain: A randomized controlled trial.

BACKGROUND AND PURPOSE: Low back pain (LBP) is a major global public health problem. Evidence shows that LBP is also related to cognitive, psychological, and lifestyle factors. Fu's subcutaneous needling (FSN) has been used for the treatment of musculoskeletal problems for many years. This prospective randomized controlled trial aimed to evaluate the clinical efficacy and fear avoidance beliefs of FSN in the treatment of patients with chronic non-specific LBP. MATERIAL AND METHODS: Ninety participants with chronic non-specific LBP were randomly divided into the FSN and the traditional acupuncture (TA) groups (n = 45) and received either FSN or TA treatment for three consecutive days from December 2021 to March 2023. The primary outcome was pain intensity measured by the visual analogue scale (VAS). Secondary outcomes were trunk extensor endurance (TEE), lumbar range of motion (ROM), and the Fear Avoidance Beliefs Questionnaire (FABQ). Outcome measurements were made before the first treatment and after each treatment. Follow-up assessments of VAS and FABQ scores were conducted one month after treatment. RESULTS: The FSN group had significantly lower VAS and FABQ scores at each time point after intervention compared to the TA group (P < 0.01). The scores of TEE and lumbar ROM were higher in the FSN group than those in the TA group (P < 0.01). Repeated measures analysis of variance (ANOVA) showed significant time effects, group effects, and interaction effects for VAS, TEE, lumbar ROM, and FABQ in both groups (P < 0.01). One month after treatment, the FSN group had significantly lower VAS and FABQ scores compared to the TA group (P < 0.05). CONCLUSION: This study suggested that FSN was superior to TA in terms of clinical efficacy and fear-avoidance beliefs in the treatment of chronic non-specific LBP. FSN could be used as an effective clinical treatment.

Bisphosphonates-related tendinopathies and ligament disorders: Cases analysis from the U.S. Food and Drug Administration adverse event reporting system.

Fluoroquinolone antibiotics are known to induce serious tendinopathies and ligament disorders (TPLDs) on rare occasion, but it is less well-appreciated whether such adverse reactions result from the use of bisphosphonates (BPs). In this study, we assessed the correlation between TPLDs and the use of BPs via U.S. FDA Adverse Event Reporting System (FAERS) database. Bayesian and nonproportional analyses were applied to data retrieved from the FAERS database from the first quarter of 2004 to the third quarter of 2022. A total of 3202 reported cases of TPLDs were associated with five BPs (alendronate, pamidronate, ibandronate, risedronate, zoledronate), with statistically significant reporting odds ratio (ROR), proportional reporting ratio (PRR), and information component (IC). Alendronate showed the highest association with tendinopathies and ligament disorders (ROR = 16.30, PRR = 15.47, IC = 3.88), while zoledronate had the lowest association (ROR = 2.13, PRR = 2.12, IC = 1.08), which was consistent with the results of top 10 preferred terms (PTs) under the narrow standardized MedDRA queries (SMQs) sorted by frequency of reports. Excluding zoledronate, over half of patients who reported BP-related TPLDs were hospitalized, either briefly or extendedly. This was especially true for alendronate, which showed the highest rate of hospitalization (83.25 %), however, the mortality rate reported by those taking alendronate were significantly lower than those of zoledronate and pamidronate. In addition, the clinical characteristics of BP-related TPLDs was analyzed. It is more common to reported in middle-aged and elderly females, the highest proportion was in 50-69 years old. Except for osteoporosis, osteopenia, and osteoporosis prophylaxis, cancer bone metastasis was also the indication of some BPs. The most often reported concomitant/prior medicines were calcium supplements, another BPs, antitumor agents, and nonsteroidal anti-inflammatory drugs. In conclusion, we provide a comprehensive overview of the correlation and clinical characteristics, and prognosis of BP-related TPLDs deserving continued surveillance and appropriate management.

The expression profile of lung long non-coding RNAs and mRNAs in a mouse model of smoke inhalation injury.

To study the potential expression of lung long non-coding RNAs (lncRNAs) and mRNAs during smoke inhalation injury (SII), using a SII mouse model that we created in our previous work. Microarray was used to investigate the lncRNAs and mRNAs profiles. A bioinformatics analysis was performed. Changes in the top 10 down-regulated and 10 up-regulated lncRNAs were validated using Quantitative Reverse Transcription-PCR (RT-qPCR). The acute lung injury (ALI) mouse model was successfully induced by smoke inhalation, as confirmed by the aberrantly modified cell numbers of red blood cells and neutrophils counts, increased levels of TNF-α, IL-1ß, Bax, caspase-7, caspase-3, and decreased Bcl-2 content in lung tissues. When compared to the control mice, 577 lncRNAs and 517 mRNAs were found to be aberrantly expressed in the SII mice. According to the Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses, the altered mRNAs were enriched in acute-phase response, oxidoreductase activity, oxidation-reduction process, glutathione metabolism, the wnt signaling pathway, and ferroptosis. A lncRNA-related competitive endogenous RNA (ceRNA) network, including 383 lncRNAs, 318 MicroRNAs (miRNAs), and 421 mRNAs specific to SII, was established. The changes in NONMMUT026843.2, NONMMUT065071.2, ENSMUST00000235858.1, NONMMUT131395.1, NONMMUT122516.1, NONMMUT057916.2, and NONMMUT013388.2 in the lung matched the microarray results. Our findings help to provide a more comprehensive understanding of the pathogenesis of SII as well as new insights into potential therapeutic targets.

Negative-pressure wound therapy in skin grafts: A systematic review and meta-analysis of randomized controlled trials.

INTRODUCTION: Although skin grafts are widely used in reconstruction of large skin defect and complex wounds, many factors lead to suboptimal graft take. Negative-pressure wound therapy (NPWT) reportedly increases the graft take rates when added to skin grafting, but a summary analysis of the data of randomized controlled trials has yet to be performed. We conducted this systematic review and meta-analysis of randomized controlled trials to compare the effectiveness and safety of NPWT and non-NPWT for patients with skin grafts. METHODS: We searched PubMed, Embase, Cochrane Library, and CNKI for relevant trials based on predetermined eligibility criteria from database establishment to February 2020. Two reviewers screened citations and extracted data independently. The quality of the included studies was evaluated according to the Cochrane Handbook, whereas statistical heterogeneity was assessed using chi-square tests and I2 statistics. Review Manager 5.3 was used for statistical analysis. RESULTS: Ten randomized controlled trials with 488 patients who underwent NPWT or non-NPWT were included. Compared with non-NPWT, NPWT yielded an improved the percentage of graft take, a reduction in days from grafting to discharge, with lower relative risk of re-operation, and no increased relative risk of adverse event. Further, the subgroup analysis showed an improved the percentage of graft take in negative pressure of 80 mmHg, and no improved the percentage of graft take in negative pressure of 125 mmHg. CONCLUSION: NPWT is more effective than non-NPWT for the integration of skin grafts, and the negative pressure of 80 mmHg can be recommended. Data on adverse events and negative pressure are, however, limited. A better understanding of complications after NPWT and the ideal negative pressure for the integration of skin grafts is imperative.

Fu's subcutaneous needling versus massage for chronic non-specific low-back pain: a randomized controlled clinical trial.

BACKGROUND: Chronic non-specific low back pain (NLBP) affects people of all ages and pose a serious threat to human health. Fu's subcutaneous needling (FSN) has been reported to be effective in treating such disorders, but the control group is lacking. The aim of this randomized parallel study is to compare the long-term efficiency of FSN therapy with massage therapy for treatment of NLBP. METHODS: A total of 60 chronic NLBP patients recruited from Yongchuan Hospital of Chongqing Medical University were randomly assigned to the FSN therapy group or massage therapy group. The main prognostic indicators included pain intensity measured on the visual analog scale (VAS), functional outcomes assessed by the Japanese Orthopedic Association (JOA) scoring system, functional disability estimated using Oswestry Disability Index (ODI), and quality of life evaluated by Short Form Health Survey Questionnaire (SF-36). These indicators were evaluated at baseline, post-treatment, 3 months after treatment, and 12 months after treatment. RESULTS: After 12 months of follow-up, we found that the 2 treatment regimens exhibited similarly favorable results in terms of all prognostic indicators in comparison with their respective baseline data (all P<0.01). However, compared with the massage group, the FSN group showed more significant improvements in VAS, JOA, and ODI at all follow-up time points, as well as SF-36 at post-treatment and 12 months after treatment (all P<0.05). CONCLUSIONS: Our findings suggest that FSN therapy is significantly more effective than massage therapy in the improvement of pain intensity, functional outcomes, functional disability, and quality of life in a long-term follow-up. However, future studies with larger sample sizes are needed to corroborate the long-term efficiency of FSN therapy for chronic NLBP.

A case report of a woman after childbirth with a dehisced abdominal wound as well as fat liquefaction and large skin necrosis.

Recently high-frequency electric knife and abdominal binder are widely used in the abdominal operation in China. Nevertheless, with the high occurrence of the abdominal wound, we think that whether both these operations could be used or not. Here, we report the case of a 40-year-old female patient where negative pressure wound therapy (NPWT) was applied to her dehisced abdominal wound as well as fat liquefaction and large skin necrosis with pleasing results. The patient with high fever was referred to our department from her earlier hospital for 6 days after cesarean delivery. During the surgery, her earlier doctor used a high-frequency electric knife for convenient-using, and after the operation, the patient immediately used an abdominal binder for good shape. However, the abdominal surgical incision was opened at postoperative day 3, with fat liquefaction releasing large fatty acids along both abdominal sides with penetration under the abdominal binder. After admitted at postoperative day 6 with aggravating wound, surgery was considered because of no reduction in the size of the wound. A series of vacuum sealing drainage (VSD) or vacuum-assisted closure (VAC) as well as others, were operated. In the admitted 25th day, the wound was completely closed. NPWT is a practical and effective therapy for the treatment of numerous refractory and intractable wounds. Therefore, we suggest that the high-frequency electric knife and an abdominal binder should be avoided using an abdominal operation. This case is the first report of the use of NPWT over a dehisced abdominal wound with fat liquefaction and large skin necrosis on a postpartum patient in China.

[The effects of high frequency oscillatory ventilation (HFOV) and HFOV combined with pulmonary surfactant treatment on lung tissue of rabbits with steam inhalation injury].

OBJECTIVE: To investigate the effects of high frequency oscillatory ventilation (HFOV) and HFOV combined with pulmonary surfactant (PS) treatment on lung tissue after steam inhalation injury in rabbits. METHODS: Twenty-four New Zealand rabbits were randomly and equally divided into three groups after reproduction of severe steam inhalation injury, each n=8. Then they were ventilated by conventional mechanical ventilation (CMV), HFOV or HFOV+PS (100 mg/kg, drip via trachea), respectively. Animals were sacrificed after 4 hours, then the middle lobe in the right lung were excised for histological sections and the degree of injury was assessed. RESULTS: Histological injury in rabbits of HFOV groups were less serious than the CMV group. Among three groups, histological injury in rabbits of CMV group was most evident and least in the HFOV+PS group. It was also found that in CMV group showed the highest score of histological injury (3.71+/-0.43), and the lowest was found in HFOV+PS group (2.08+/-0.28), and that of HFOV group was 2.87+/-0.26. Comparison between whichever two of the three groups showed statistical significance (P<0.05 or P<0.01). CONCLUSION: HFOV can alleviate pulmonary edema and infiltration of inflammation cells, and it is shown that HFOV combined with exogenous PS gives the best outcome.

Theoretical insights on the comparison of champion dyes SM315 and C275 used for DSSCs reaching over 12% efficiency and the further optimization of C275.

Theoretical insights on the comparison between the champion dyes SM315 and C275 used for high-performance dye-sensitized solar cells (DSSCs) reaching over 12% efficiency with different electron donors only (porphyrin for SM315 and indenoperylene for C275) were explored for the first time. The intrinsic reasons for the significantly improved monochromatic photon-to-electric current conversion efficiency (IPCE) and open circuit voltage (Voc) of C275-based DSSCs over those of SM315 were revealed. According to our results, we find that the larger IPCE of C275 is attributed to its larger electronic coupling, smaller reorganization energy, reduced exciton binding energy and enhanced charge transfer character, all of which when combined lead to a larger electron injection efficiency. In addition, the larger Voc of C275 is due to a greater number of injected electrons, a smaller molecular volume and a smaller projected area, which lead to a more compact adsorption layer with a hindered charge recombination process. Thus, C275 is expected to have more potential to further optimize high-performance DSSCs. In view of the primary shortcoming of C275, which is its relatively narrow absorption spectrum, further optimization was made through structural modification using a series of heterocyclic anchoring groups. Using the same evaluation criteria, the theoretical screening of these dyes based on C275 is carried out. We find that indenoperylene dye with a barbituric acid (BA) anchoring group is a promising candidate for the experimental synthesis of high-performance DSSCs with improved Jsc, Voc and adsorption stability.

[Systematic review and analysis on the appropriate diseases in clinical treatment with Fu's subcutaneous needling therapy].

The clinical research articles relevant with Fu's subcutaneous needling therapy (FSN) were retrieved from CNKI, WANFANG, CBM and PubMed databases till January 2018 since the establishment of database. According to the general international criteria of disease classification, the diseases involved in the articles were classified and summarized. In terms of the clinical application and research of FSN, the questions were extracted and commented through expert's consultation. As a result, 412 articles were included. The statistical results of disease spectrum indicated that FSN was adopted in 65 kinds of diseases in 11 systems. Of these diseases, the relevant somatic pain disorders in the musculoskeletal system were the most appropriate. Professor FU Zhong-hua explained that the clinical physicians of FSN should select the muscle-related disorders as the clinical research subject and treat them with normalized manipulation of FSN. The research on FSN is still at the preliminary stage. It needs more high-quality clinical and basic researches to provide the evidences for the therapeutic effects of FSN.

[Effect of high frequency oscillatory ventilation combined with exogenous pulmonary surfactant on apoptosis of lung tissue in rabbit with acute respiratory failure induced by steam inhalation injury].

OBJECTIVE: To investigate the effect of high frequency oscillatory ventilation (HFOV) combined with exogenous pulmonary surfactant (PS) on apoptosis of lung tissue in rabbit suffering from steam inhalation injury. METHODS: Thirty-two New Zealand rabbits were randomly divided into four groups, and acute respiratory failure model was reproduced by severe steam inhalation injury. Then they were ventilated and treated by controlled mandatory ventilation (CMV), HFOV, CMV+PS or HFOV+PS, respectively. After the animals were euthanized at 4 hours treatment time point, the right middle lobe of rabbit lung was harvested for the examination of caspase-3 and p73 contents and relative values, as well as mRNA expression of caspase-3 and p73. RESULTS: (1)Contents of caspase-3 and p73 in lung tissue homogenates in HFOV group and HFOV+PS group were significantly lower than those in CMV group and CMV+PS group (P<0.05 or P<0.01), and also contents of caspase-3 and p73 in lung tissue homogenates in groups with exogenous PS were significantly lower than those of groups without exogenous PS (all P<0.05). (2) Caspase-3, p73 mRNA expressions in lung tissue in HFOV group and HFOV+PS group were significantly lower than those of CMV group and CMV+PS group (all P<0.01). Caspase-3 and p73 mRNA expression in lung tissue in groups with exogenous PS group were significantly lower than those of the corresponding group without exogenous PS (all P<0.05). CONCLUSION: Compared with CMV or CMV+PS, HFOV or HFOV+PS can decrease the concentration of caspase-3 and p73, reduce the mRNA expression of caspase-3 and p73 in the lung homogenates, as a result lung tissue apoptosis in inhalation injury may be suppressed.

Fu's subcutaneous needling: possible clinical evidence of the subcutaneous connective tissue in acupuncture.

OBJECTIVES: Recently it was reported that the loose connective tissue in the subcutaneous layer rapidly responded to mechanical forces evoked by acupuncture, massage, and normal physical movements. However, there were no clinical studies to substantiate these findings so far. Fu's Subcutaneous Needling (FSN) is the innovative needling strategy acting specifically in the subcutaneous layer. A single-blinded and randomized trial was designed to compare the immediate effects of FSN with different needling directions on myofascial trigger points (MTrP) in the neck. DESIGN: For simplicity, we chose two mutually perpendicular needle directions in this study. In one group, the needle was along the local muscle fibers and pointed to the MTrP (Along Group). In the other group, the needle was across the local muscle fibers and also pointed to the MTrP (Across Group). SUBJECTS: Forty-seven (47) patients were randomly divided into two groups: the Along Group (n = 22) and the Across Group (n = 25). There were no significant differences with respect to age, duration of pain, and gender between the two groups. INTERVENTIONS: FSN needles were inserted and swayed in the subcutaneous layer 200 times in 2 minutes. RESULTS: Before and after FSN treatment, patients were subjected to the assessment of the following three parameters: motion-related pain, pain under pressure, and the range of cervical movement. Three parameters were all reduced after the FSN intervention. There were no significant differences in variation of the three parameters between the two groups. CONCLUSION: Immediate effects of FSN on alleviating MTrP in the neck were not relevant to the needling directions.

Early anticoagulation therapy for severe burns complicated by inhalation injury in a rabbit model.

The aim of the present study was to determine the effects of early anticoagulation treatment on severe burns complicated by inhalation injury in a rabbit model. Under anesthetization, an electrical burns instrument (100˚C) was used to scald the backs of rabbits for 15 sec, which established a 30% III severe burns model. Treatment of the rabbits with early anticoagulation effectively improved the severe burns complicated by inhalation injury­induced lung injury, reduced PaO2, PaCO2 and SPO2 levels, suppressed the expression of tumor necrosis factor­α, interleukin (IL)­1ß and IL­6, and increased the activity of IL­10. In addition, it was found that early anticoagulation treatment effectively suppressed the activities of caspase­3 and caspase­9, upregulated the protein expression of vascular endothelial growth factor (VEGF) and decreased the protein expression of protease­activated receptor 1 (PAR1) in the severe burns model. It was concluded that early anticoagulation treatment affected the severe burns complicated by inhalation injury in a rabbit model through the upregulation of VEGF and downregulation of PAR1 signaling pathways. Thus, early anticoagulation is a potential therapeutic option for severe burns complicated by inhalation injury.

Comparison of conventional mandatory ventilation and high frequency oscillatory ventilation for treatment of acute lung injury induced by steam inhalation injury.

This study compared patho-physical indexes, respiratory mechanics, circulatory parameters and lung injury scores of acute lung injury (ALI) induced by steam inhalation injury in a New Zealand rabbit model with different ventilatory strategies: a control group which consisted of lower tidal volume (VT 6 ml/kg) and high positive end-expiratory pressure (PEEP) (9 cmH(2)O); treatment group which was high frequency oscillatory ventilation (HFOV). Eighteen rabbits were anaesthetized, sedated, neuromuscular-blocked and ventilated with above two modes at our animal laboratory of burn center. After induction of acute lung injury by steam inhalation, animals were randomly assigned to receive either conventional mechanical ventilation (CMV) or high frequency oscillatory ventilation and were grouped as CMV and HFOV group. As a result, HFOV attenuated the decrease in oxygenation and pulmonary compliance, alleviated lung tissue damage and inflammatory response. Therefore, HFOV may be a preferable option for treatment of acute lung injury induced by steam inhalation injury.

[The enlightenment of Fu's subcutaneous needling on pain medicine].

Fu's subcutaneous needling (FSN) is a modern approach developed from traditional Chinese acupuncture. It could give some stimulation in the subcutaneous region that has a quick and long-lasting effect on soft tissue injuries and some of the internal medicine diseases. It is a safe approach without adverse reaction. Through analysis of the features and possible mechanism of FSN, it is believed that research on mechanism of FSN is beneficial to the development of modern medicine, especially to pain management.

[Review on the role of Fu's subcutaneous needling (FSN) in pain relieving].

Through retrieval of all medical journals of CNKI and VIP from Jan. 1996 to Oct. 2012, ninety-nine articles were selected and analyzed. The result shows that reliable effect can be found in pain relieving, especially in pain of muscles and soft tissues. In mechanism research, action mechanism of Fu's subcutaneous needling (FSN) on pain relieving is expounded through theory of traditional medicine and modern medicine. Although the effect of FSN on pain relieving has been confirmed by numerous clinical trials, it is still lack of explanation on mechanism revealing. The further studies should focus on mechanism expounding, improving research methods and selecting more objective and reasonable evaluation system. Therefore, the effectiveness and scientificalness of FSN can be further enhanced.
