ABSTRACT
BACKGROUNDAND 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.
ABSTRACT
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.

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.
ABSTRACT
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.

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.

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.

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.

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.

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.

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.
ABSTRACT
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.

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.

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 (100ËC) 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.

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.

OBJECTIVE: To study the effects of high frequency oscillatory ventilation (HFOV) combined with incremental positive end-expiratory pressure (IP) on respiratory and circulatory functions, and lung histopathology of dogs with smoke inhalation injury. METHODS: After being treated with conventional mechanical ventilation, 12 dogs were inflicted with severe smoke inhalation injury and divided into group HFOV and group HFOV+IP according to the random number table, with 6 dogs in each group. Then they received corresponding ventilation for 8 hours respectively. Blood gas analysis results (pH value, PaO2 and PaCO2 levels) and hemodynamic parameters [heart rate, mean arterial pressure (MAP), pulmonary arterial pressure (PAP), central venous pressure (CVP), cardiac output (CO)] were recorded before injury, immediately after injury, and at post ventilation hour (PVH) 2, 4, 6, and 8. The dogs of two groups were sacrificed at PVH 8. A healthy dog without any treatment and a dog with smoke inhalation injury but no subsequent treatment were sacrificed in addition. Lung tissues of all dogs were obtained for histopathological observation. Lung injury score examination was conducted in both groups. Data were processed with rank sum test, analysis of variance of repeated measurement, and LSD- t test. RESULTS: (1) The PaO2 levels in both groups were significantly decreased immediately after injury, compared with those before injury (with t values respectively 4.960, 5.310, P values all below 0.01). The PaO2 levels in both groups from PVH 2 to PVH 8 were significantly increased, compared with those observed immediately after injury (with t values from 4.930 to 6.050, P values all below 0.01). At PVH 2, 4, and 8, PaO2 levels in group HFOV+IP were significantly higher than those in group HFOV (with t values from 3.775 to 5.774, P values all below 0.01); no statistically significant differences were observed in pH value and PaCO2 level at each time point between two groups (with t values from 0.002 to 0.997, P values all above 0.05). (2) There were no statistically significant differences in MAP, PAP, and CVP within two groups at each time point (with F values from 1.316 to 4.959, P values all above 0.05). In group HFOV, heart rate from PVH 2 to PVH 8 was significantly lower than that observed immediately after injury (with t values from 3.780 to 8.970, P values all below 0.01). In group HFOV+IP, CO at PVH 4, 6, and 8 was significantly lower than that observed immediately after injury (with t values from 3.990 to 11.200, P values all below 0.01). There were no statistically significant differences in MAP, PAP, and CVP between two groups at the same time point (with t values from 0.089 to 2.123, P values all above 0.05). At PVH 4, 6, and 8, heart rate in group HFOV+IP was higher than that in group HFOV (with t values from 2.931 to 7.229, P < 0.05 or P < 0.01), while CO was lower (with t values from 4.297 to 11.206, P values all below 0.01). (3) Compared with those of the healthy dog, inflammatory cell infiltration and bleeding in the lung were observed in alveolar space in both group HFOV and group HFOV+IP, while the degree was less serious than that of the dog with smoke inhalation injury only. Compared with those of group HFOV, inflammatory cell infiltration in group HFOV+IP was less significant, the alveolar structure was relatively intact, and no thickening of alveolar walls was observed. The lung injury score in group HFOV [(3.27 ± 0.24) points] was higher than that of group HFOV+IP [(2.79 ± 0.31) points, t = 27, P < 0.05]. CONCLUSIONS: HFOV combined with IP can improve gas exchange and alleviate pulmonary injury without any adverse effect on blood gas analysis or hemodynamic parameters. Therefore, it may be considered as an appropriate mode of ventilation for the treatment of smoke inhalation injury.

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.

OBJECTIVE: To compare the effect of high frequency oscillatory ventilation (HFOV) and conventional mandatory ventilation (CMV) on the myocardial function of rabbits with inhalation injury. METHODS: Steam inhalation injury model was reproduced in 16 New Zealand albino rabbits. They were randomly divided into CMV group (n = 8) and HFOV group (n = 8) by drawing lots, and they received ventilation in metered volume and HFOV treatment respectively. Heart blood was drawn from rabbits before they were sacrificed 4 hours after treatment to determine the plasma activity of lactate dehydrogenase 1 (LDH1) and creatine phosphorylated kinase (CPK-MB). Myocardial tissue from left ventricle was harvested and homogenized to determine the concentration of TNF-α and IL-8, the activity of caspase-1, and the activity of myosin-light-chain kinase (MLCK) and the ATPase of myosin light chain (MLC-ATPase) by enzyme-linked immunosorbent assay, spectrophotometry, and the nuclide liquid scintillation technique respectively. Part of the myocardial tissue sample was examined pathologically. Data were processed with analysis of variance. RESULTS: (1) The activities of LDH1 and CPK-MB in plasma were obviously higher in CMV group than in HFOV group [(643 ± 108), (342 ± 48) U vs. (233 ± 92), (186 ± 36) U, with F value respectively 10.326 and 9.846, P values all below 0.01]. (2) The contents of TNF-α, IL-8 and the activity of caspase-1 in myocardial tissue homogenate were obviously higher in CMV group than in HFOV group [(181 ± 35), (89 ± 19) pg/g, and (0.56 ± 0.27) g/g protein vs. (94 ± 21), (43 ± 11) pg/g, and (0.24 ± 0.12) g/g protein, with F value respectively 8.239, 7.826, 5.716, P values all below 0.01]. (3) The activities of MLC-ATPase and MLCK were lower in CMV group than in HFOV group [(0.24 ± 0.12) µmol×mg(-1)×min(-1), (3.3 ± 1.1) mmol×mg(-1)×min(-1) vs. (0.48 ± 0.16) µmol×mg(-1)×min(-1), (7.7 ± 1.7) mmol×mg(-1)×min(-1), with F value respectively 4.125, 4.766, P values all below 0.01]. (4) No obvious necrosis, degeneration or inflammatory cell infiltration was observed in myocardial tissue of rabbits in 2 groups under light microscope; but the myocardial fiber was slightly swollen, and it was less marked in the HFOV group. CONCLUSIONS: The influence of HFOV on myocardial myosin phosphorylation system of rabbits with inhalation injury is less than that of CMV.

Literatures on acupuncture analgesia of the recent 30 years are analyzed through the target pain syndromes, points and tools selected for needling as well as the chosen direction, angle and depth of insertion. The relationship between effect of acupuncture analgesia and needling direction, angle as well as depth is initially optimized to enhance the analgesic effect. The result shows that the 3 factors are the key influences. However, studies on the above mentioned relation are still far from enough. Aiming at enhancing the effect of acupuncture analgesia and exploring the relative mechanism, it is held that multivariate analysis should be adopted to do systematic analysis on relationship between effect and mechanism of acupuncture analgesia and direction, angle and depth of the needle insertion.
