[Clinical characteristics and prognosis analysis of pulmonary sarcomatoid carcinoma].

Objective: To summarize the clinical characteristics, treatment, and outcomes of patients with pulmonary sarcomatoid carcinoma (PSC) in order to improve clinicians' understanding of this disease. Methods: The clinical data of patients diagnosed with PSC in our hospital from January 1, 2015 to November 30, 2023 were retrospectively analyzed. According to whether radical resection was performed, the patients were divided into resectable group and unresectable group. The characteristics and treatments of PSC in different groups were compared. The survival curves were drawn by Kaplan-Meier method to compare the prognosis of different groups of patients. Results: A total of 43 PSC patients were included, including 32 males, with an average age of (62.79±9.59) years, and 31 smokers. Peripheral-type tumors were more common, with imaging showing predominantly solid soft tissue masses, and the maximum diameter of the tumor was more than 5 cm in 14 patients. Among the 23 patients who underwent NGS gene testing, the KRAS mutation rate was 43.5%, the TP53 mutation rate was 30.4%, and the MET mutation rate was 8.7%, all of which were MET-14 exon skipping mutations. PD-L1 expression was detected in 13 patients, 10 of whom showed high expression. The median overall survival (mOS) of the 43 patients with PSC was 24.6 months (13.0-52.7 months). Among them, 22 patients underwent radical lobectomy plus mediastinal lymph node dissection, 13 patients had postoperative recurrence, and 7 patients died during follow-up. The median disease-free survival (mDFS) was 12.3 months, the mOS was not achieved and the 1-year OS rate was 77.3 %. Twenty-one patients had unresectable locally advanced or advanced stage, and 15 patients died. The mDFS was 2.5 months, the mOS was 6.2 months, and the 1-year OS rate was 42.9 %. Seventeen patients received immunotherapy, and 1 patient received targeted therapy with the MET inhibitor glumetinib. Conclusions: PSC has a higher incidence in the elderly, smokers, and males, is highly malignant and has a poor prognosis. Based on its molecular biological characteristics, PD-L1 expression and tumor molecular detection can be performed to guide treatment options.

[The prevalence of insufficient physical activity and the influencing factors among Chinese adults in 2018].

Objective: To understand the prevalence of insufficient physical activity among adults aged ≥18 years in China and to explore the influencing factors. Methods: The China Chronic Disease and Risk Factor Surveillance was conducted in 298 counties/districts in China in 2018, covering 31 provinces (autonomous regions, municipalities). A multi-stage stratified cluster random sampling method was used to select permanent residents aged ≥18 years. A questionnaire including Global Physical Activity Questionnaire was used to collect information about the participants' demographic characteristics and physical activity through face-to-face interview. A total of 183 769 participants completed the survey. After complex data weighting, the prevalence of insufficient physical activity, occupation, transportation, and leisure-time physical activity time was analyzed. Multivariate logistic regression models were used to analyze the influencing factors related to insufficient physical activity. Results: The prevalence of insufficient physical activity among adults aged ≥18 years was 22.3% (95%CI: 20.9%-23.7%) in China in 2018, with males [24.4% (95%CI: 23.0%-25.8%)] significantly higher than females [20.2% (95%CI: 18.6%-21.8%)]. Adults aged 70 years and above [28.4% (95%CI: 26.9%-29.9%)] were significantly higher than adults in other age groups, followed by adults aged 18-29 years [26.4% (95%CI: 24.4%- 28.3%)] and 30-39 years [23.4% (95%CI: 21.5%-25.3%)], and tended to increase with increasing education and total sedentary behavior time (P<0.001). The weekly occupation, transportation, and leisure-time physical activity time appeared 958.6 (95%CI: 911.4-1 005.8) minutes, 234.5 (95%CI: 224.7- 244.2) minutes, and 88.6 (95%CI: 83.5-93.7) minutes, respectively. Multivariate logistic regression analysis showed that males, adults living in rural areas or northern China, ≥70 years, with junior high school education, an annual household income per capita <6 000 yuan and institutional/clerical/ technical occupation and longer total sedentary behavior time were related to a higher prevalence of insufficient physical activity. Conclusions: In China, over one-fifth of the adults had lower physical activity levels. Adults who are male, young adults, more educated, institutional/clerical/technical occupation, and with more extended total sedentary behavior are the populations that need to be focused on to promote physical activity-related health.

[Cardiovascular health status of Chinese adults based on "Life's Essential 8" score].

Objective: To assess the cardiovascular health status of adults in China by using the "Life's Essential 8" score, and provide reference for the development and improvement of cardiovascular disease prevention and control policies and measures. Methods: Chronic Disease and Nutrition Surveillance was conducted in 298 counties/districts in 2015 in 31 provinces (autonomous regions, municipalities) across China, multi-stage stratified cluster random sampling was used to select 45 households in each village or neighborhood, and 20 households were further selected to conduct dietary surveys. In this study, a total of 70 093 adults aged ≥20 years who completed the dietary survey and had complete information were included, their cardiovascular health status were assessed by using the "Life's Essential 8" score, a cardiovascular health scoring standard released by the American Heart Association in 2022. All results were adjusted using complex design-based sampling weights to achieve a better estimate of the population. Results: In 2015, the overall cardiovascular health score of Chinese adults aged ≥20 years was 73.3±12.6, the score was significantly higher in women (77.9±11.6) than in men (68.7±11.8), and higher in urban area (74.5±12.8) than in rural area (71.9±12.2), the differences were significant (P<0.001). It was estimated that about 0.25% (95%CI: 0.16%-0.33%) of adults in China had cardiovascular health score of 100, and 33.0% (95%CI: 31.6%-34.3%), 63.2% (95%CI: 62.1%-64.3%), and 3.9% (95%CI: 3.5%-4.2%) of adults had high, moderate and low cardiovascular health scores, respectively. The proportion of those with high cardiovascular health scores was relatively low in men, those with low education level, those with low income, those living in rural areas, and those living in southwest China (P<0.001). Of the eight factors, diet had the lowest mean score (46.0, 95%CI: 44.7-47.3), followed by blood pressure (59.4, 95%CI: 58.2-60.6) and tobacco exposure (61.4, 95%CI: 60.6-62.2). Conclusions: The cardiovascular health status of two-thirds of adult population in China needs to be improved. Diet, tobacco exposure, and blood pressure are the factors affecting the cardiovascular health of Chinese population, to which close attention needs to be paid, and men, rural residents, and those with lower socioeconomic status are key groups in cardiovascular health promotion.

[Research on the association between physical activity and type 2 diabetes].

Type 2 diabetes mellitus (T2DM) has become a significant public health problem affecting the health of our population. Physical inactivity is a significant risk factor for the occurrence and development of major chronic diseases, including T2DM, and appropriate physical activity patterns and levels have positive implications for the prevention and treatment of T2DM. This paper reviews the progress and results of domestic and international studies on the relationship between physical activity and the occurrence, development, and mortality of T2DM in recent years to support the improvement of strategies and measures for the prevention and management of diabetes in general and high-risk populations in China.

[Analysis of blood pressure measurement among Chinese adults in 2018].

Objective: To analyze the blood pressure measurement of Chinese adult residents in 2018 and provide a scientific basis for early detection and intervention of hypertension. Methods: In 2018, China Chronic Disease and Risk Factor Surveillance were conducted in 298 counties (districts) of 31 provinces (autonomous regions, municipalities) across the country, using a multi-stage stratified cluster random sampling method to survey permanent residents aged 18 years and above. We selected 184 509 people and carried out a face-to-face questionnaire survey and body measurement method to collect demographic data, major chronic diseases, and blood pressure measurement information of the survey subjects. Blood glucose and blood lipid-related indicators were obtained by laboratory testing. There were 170 551 adult residents included in the study after excluding abnormal and missing data for key variables. After complex weighting, blood pressure detection rates and detection times in people with different blood pressure levels and other diseases were analyzed. SAS 9.4 software was used to perform the χ2-test and trend test. Results: Among adult residents in China, the proportions of those with normal blood pressure, commonly recognized 'high' blood pressure, and newly detected hypertension who had their blood pressure tested within three months were 44.4%, 50.4%, and 52.6%, respectively. The proportions all appeared higher in women than in men (all P<0.05), in urban than in rural areas (all P<0.05), and showed an increasing trend with age (all P<0.001); The proportion of these three populations who had never had their blood pressure measured was 27.6%, 24.2%, and 23.5% respectively. The proportion of people with diagnosed hypertension who had their blood pressure tested within seven days was 44.0%, 51.4% in urban areas, higher than 37.7% in rural areas (P<0.001), and the proportion of people who had their blood pressure tested increased with education, per capita annual income and BMI (all P<0.001). Conclusions: The behavior of regular self-monitoring of blood pressure among adult residents in China still needs to be improved, especially among men and rural areas. Relevant health promotion and education should be strengthened. More targeted policies and measures should be developed to improve blood pressure measurement behavior in people with normal high blood pressure and other high-risk groups to control elevated blood pressure effectively.

[Awareness and influencing factors on weight and waist circumference among adult Chinese residents in 2018].

Objective: To understand the awareness of weight and waist circumference and their influencing factors among residents aged ≥18 years in China and provide a reference for the development of relevant prevention and treatment policies and evaluation of intervention effects. Methods: We selected 298 counties (districts) from the 31 provinces (autonomous regions and municipalities) which participated in the 2018 China Chronic Disease and Risk Factor Surveillance program and included 194 779 permanent residents aged ≥18 years. To obtain the demographic characteristics of the study population, we used a multi-stage stratified whole-group random sampling method, questionnaires, and physical measurements. In this study, 179 045 people who completed the survey and had complete information on weight and waist circumference awareness were used as the study subjects. The weight awareness rate and waist circumference awareness rate were calculated by gender stratification, age, urban-rural, and education level groups. A multi-factor logistic regression model was used to analyze the influencing factors related to weight and waist circumference awareness of residents aged ≥18 years. Results: The weight awareness rate of adult residents in China in 2018 was 45.4% (95%CI: 41.9%-48.9%), higher among men [46.2% (95%CI: 42.5%-49.8%)] than women [44.6% (95%CI: 41.1%-48.2%)], and in urban areas [54.3% (95%CI: 49.3%-59.3%)]. The highest weight awareness rate appeared in residents with low BMI grouping [49.9% (95%CI: 44.3%-55.6%)], and the weight awareness rate in residents with undiagnosed central obesity, hypertension, and diabetes was higher than that of residents with diagnosed diabetes, with statistically significant differences (P<0.05). The waist circumference awareness rate of adult residents was 11.6% (95%CI: 9.7%-13.4%), higher in women [12.8% (95%CI: 10.8%-14.8%)] than in men [10.3% (95%CI: 8.6%-12.0%)], higher in urban [14.6% (95%CI: 11.7%-17.4%)] than in rural [8.3% (95%CI: 6.5%-10.2%)], and the waist circumference awareness rate was higher among residents with confirmed diabetes than those with undiagnosed diabetes, with statistically significant differences (P=0.020). The difference was statistically significant (P<0.001). The weight and waist circumference awareness rate increased with education level and annual per capita household income. Multi-factor logistic regression analysis suggested that urban, highly educated, high per capita annual household income and health check-up residents may have higher weight and waist circumference awareness rates among adult residents in China. Conclusion: Less than half of the adult residents in China know their weight status, and only about one-tenth know their waist circumference. Rural residents, those with low education levels and low annual per capita household income, and those who are obese need to be given prioritized attention. The relevant government departments should strengthen the popularization of the importance of weight and waist circumference on health and improve the awareness of our residents about their waist circumference and weight.

[Research advances of music therapy and its application in the field of burn treatment].

Different from other trauma, the scar and pigmentation formed after healing of burn wound not only hinder beauty but also easily lead to a series of sequential psychological problems, such as depression and anxiety. Music therapy, as a supplementary treatment, is widely used in many fields including medical and health care and psychological regulation. However, affected by factors such as medical resources, the awareness and acceptance of music therapy among burn treatment workers in China are still low. Based on the clinical characteristics of burns, this paper matches the applicability of music therapy with it, summarizes the supplementary application of music therapy in the field of burn treatment, expounds this natural science with both science and aesthetics, and puts forward feasible suggestions for its future development.

[Effect analysis of sequential laser application in treating the hypertrophic scars of burn children at early stage].

Objective: To explore the effects of sequential application of intensive pulsed light and carbon dioxide laser in treating the hypertrophic scars of burn children at early stage. Methods: A retrospective cohort before-after control study in the same patients was conducted. From January 2016 to December 2018, 145 burn children with hypertrophic scar at the early stage who met the inclusion criteria were admitted to the First Hospital of Jilin University, including 82 males and 63 females, aged 1 to 12 (3 (2, 6)) years. All the children were firstly treated with intense pulsed light therapy (no anesthesia or intravenous-inhalation combined anesthesia) at an interval of once per month, and then changed to carbon dioxide laser therapy (topical anesthesia or intravenous-inhalation combined anesthesia) when the degree of scar hyperemia was reduced, at an interval of once every 3 months, for a total of 3 times. Before the first intense pulsed light treatment (hereinafter referred to as before the first treatment) and 3 months after the last carbon dioxide laser treatment (hereinafter referred to as after the last treatment), scar scoring was evaluated by Vancouver Scar Scale (VSS), and scar hyperemia (denoted as hemoglobin level) was measured with Antera 3D® camera. The times of intense pulsed light, the time of single treatment, the anesthesia method, and the time of intravenous-inhalation combined anesthesia of intense pulsed light and carbon dioxide laser treatment were analyzed. After the last treatment, Likert Scale was used to evaluate the efficacy satisfaction of both doctors and patients. Adverse reactions were recorded during the treatment. Data were statistically analyzed with Wilcoxon signed rank sum test, and paired sample t test. Results: The color, vascular distribution, thickness, and softness scores, and total score in VSS scoring of scars of children after the last treatment were significantly lower than those before the first treatment (Z=-6.05, -10.34, -9.84, -9.28, -10.43, P<0.01). The hemoglobin level of scar of children after the last treatment was 1.86±0.24, significantly lower than 2.27±0.32 before the first treatment (t=17.65, P<0.01). A total of 411 times of intense pulsed light therapy were performed, (2.8±0.6) times per person, and the single treatment time was 35 (20, 45) s. There were 392 times (95.38%) without anesthesia, and 19 times (4.62%) with intravenous-inhalation combined anesthesia with time of 6 (5, 8) min. The single treatment time of carbon dioxide laser therapy was 5 (3, 10) min. There were 364 times (83.68%) of topical anesthesia and 71 times (16.32%) of intravenous-inhalation combined anesthesia with time of 10 (8, 15) min. After the last treatment, the efficacy satisfaction scores of doctors and patients were (4.3±0.7) and (3.8±1.0) points, respectively. Blisters occurred in 5 cases after intense pulsed light treatment, which were healed naturally after drainage. One child developed local skin infection, skin redness and swelling accompanied by purulent exudate after carbon dioxide laser treatment, which was improved after skin disinfection and external use of mupirocin ointment. No inflammatory pigmentation, worsening of hyperplasia of scar, erythema, or other skin adverse reactions or anesthetics-related adverse reactions occurred in any child. Conclusions: Sequential application of intense pulsed light and carbon dioxide laser to treat the hypertrophic scars of burn children at early stage can obviously improve the appearance and texture of scar, with higher satisfaction of doctors and patients and fewer adverse reactions.

[Effects of recombinant human granulocyte macrophage colony stimulating factor gel on treatment of full-thickness frostbite wounds on foot and hand].

Objective: To explore the effects of recombinant human granulocyte macrophage colony stimulating factor (rhGM-CSF) gel on treatment of thefull-thickness frostbite wounds on foot and hand. Methods: From November 2013 to April 2017, a total of 45 patients of 71 full-thickness frostbite wounds on foot and hand meeting the inclusion criteria were admitted to the First Hospital of Jilin University and the prospective randomized controlled study was done. The patients were divided into rhGM-CSF group of 24 patients with 35 wounds and control group of 21 patients with 36 wounds according to the random number table. There were 20 males and 4 females, aged (38±13) years among patients in rhGM-CSF group, and there were 19 males and 2 females, aged (36±14) years among patients in control group. Patients in 2 groups were performed with the same systemic treatment of rewarming, anti-inflammation, pain relief, anti-infection, anti-coagulation, and thrombolysis. Wounds of patients in rhGM-CSF group and control group were respectively treated with rhGM-CSF gel and aloe vera gel for external usage with 10 mg for every square centimeter and dressing change once every 24 hours, until wounds healed completely. The wound inflammatory response was scored on treatment day (TD) 1, 3, 7, 14, wound secretion was collected for bacteria culture and positive bacteria detection rate was calculated before treatment and on TD 6 and 12, adverse drug reaction after drug use was observed, and the complete wound healing time was recorded. Data were processed with Fisher's exact probability test, analysis of variance for repeated measurement, t test, and Bonferroni correction. Results: The scores of wound inflammatory response of patients in 2 groups on TD 1 and 3 were close (t=0.37, 2.93, P>0.05). The scores of wound inflammatory response of patients on TD 7 and 14 in rhGM-CSF group were significantly higher than those in control group (t=5.77, 5.83, P<0.01). The results of bacteria culture of wound secretion of patients in 2 groups before treatment were negative. The positive bacteria detection rates of wound secretion of patients in rhGM-CSF group on TD 6 and 12 were 5.71% (2/35) and 22.86% (8/35), which were slightly lower than 13.89% (5/36) and 30.56%(11/36) in control group respectively, but there was no significantly statistical difference (P>0.05). No adverse drug response occurred in patients in rhGM-CSF group, while 1 patient in control group had adverse drug response, with symptoms of redness and swelling of wounds and patchy erythema on skin around wounds, which were alleviated by irrigating with normal saline. The complete wound healing time of patients in rhGM-CSF was (12.3±0.5) d, which was significantly shorter than (16.5±0.8) d in control group (t=24.89, P<0.05). Conclusions: The topical rhGM-CSF gel has effects of shortening time of wound healing and reducing inflammatory response of wound on treatment of full-thickness frostbite wounds on foot and hand, which is safe in clinical application.

[Minor similarities and major differences between cold injury and burn injury].

Cold injury is very damaging. This article summarizes the mechanism, types, and rehabilitation of cold injury, focusing on the degree and clinical treatment of frostbite. Frostbite can mainly cause damage of microcirculation and capillary structure, while burn injury can mainly cause damage of cutaneous tissues. Based on this, the key point of management of frostbite is to improve microcirculation and appropriate rewarming, while that of burn injury is wound repair. Up to date, the rate of amputation caused by frostbite is still high, and the rehabilitation for sequela caused by frostbite remains a big challenge in modern medicine. It is worth paying more attention to.

[Bacterial biofilm and chronic wound infection].

Bacteria usually colonize, reproduce, and grow aggressively on chronic wounds in the form of biofilm. Different from free bacteria, bacteria in biofilm exhibit unique mechanism in epigenetics and biological behavior, especially in resistance to antibiotics and host immunity. In this article, we introduce the composition and structural function of bacterial biofilm, expound the drug-resistance mechanism of bacterial biofilm, discuss the clinical characteristics of bacterial biofilm infection wound and the diagnosis method of biofilm, and analyze the treatment strategy for bacterial biofilm. It is suggested that clinicians should pay more attention to bacterial biofilm infection and advocate in-depth study of bacterial biofilm in order to improve the quality of managing chronic wounds.

Silence of MiR-9 protects depression mice through Notch signaling pathway.

OBJECTIVE: To investigate the potential influence of micro ribonucleic acid (miR)-9 on depressive behaviors of depression mice. MATERIALS AND METHODS: Depression model in mice was established via chronic unpredictable mild stress. A total of 36 C57BL/6 mice were randomly divided into control group (control mice, n=12), model group (depression mice administrated with control lentivirus, n=12) and miR-9 low-expression group (depression mice administrated with LV-miR-9-shRNA lentivirus, n=12). After 6 weeks, the depressive behaviors of mice were evaluated by behavioral experiments. Mice were then sacrificed for harvesting the hippocampus. Relative level of miR-9 in mouse hippocampus was determined via quantitative polymerase chain reaction (qPCR). Moreover, the number of newborn neurons in the hippocampus in each group was detected via immunofluorescence assay. Expression levels of doublecortin (DCX), post-synaptic density protein 95 (PSD95) and Notch signaling pathway in the hippocampus in each group were detected via Western blotting. RESULTS: In the open field test, there were no significant differences in the crossing score and rearing score among control group, model group and miR-9 low-expression group (p>0.05). The immobility time of mice in tail suspension test and forced swimming test increased significantly in model group compared with that in control group (p<0.01), while it was significantly shorter in miR-9 low-expression group than that in model group (p<0.01). The expression of miR-9 in mouse hippocampus in model group was significantly higher than that in control group and miR-9 low-expression group (p<0.01). In miR-9 low-expression group, the number of newborn neurons in the hippocampus was significantly larger than that in control group and model group (p<0.01). Protein levels of both DCX and PSD95 were significantly higher in control group than those in model group (p<0.01). Besides, protein levels of Notch intracellular domain (NICD), Hes1 and Jag1 in the hippocampus in model group were remarkably declined compared with those in control group (p<0.01), which were higher in miR-9 low-expression group. CONCLUSIONS: MiR-9 is upregulated in the hippocampus of depression mice. Silence of miR-9 in the hippocampus can effectively activate the Notch signaling pathway, promote the neuronal regeneration in the hippocampus and improve the depressive symptoms of mice.

Preliminary results indicate resveratrol affects proliferation and apoptosis of leukemia cells by regulating PTEN/PI3K/AKT pathway.

OBJECTIVE: PTEN-PI3K/AKT signaling pathway is widely involved in the regulation of cell proliferation, cell cycle, apoptosis, and invasion. Resveratrol (Resv) is a natural botanical ingredient involved in several biological activities. It is still unclear in terms of whether Resv may exert anti-leukemia effects by regulating the PTEN-PI3K/AKT pathway. This study investigated the effect of Resv on leukemia cell proliferation and apoptosis by regulating PTEN-PI3K/AKT pathway. PATIENTS AND METHODS: Human normal peripheral blood PBMC cells, and human acute promyelocytic leukemia (APL) cell line NB-4 and HL-60 cells were cultured in vitro. Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to detect Phosphatase and tensin homolog (PTEN) mRNA expression. Western blot was adopted to test PTEN protein expression. HL-60 and NB-4 cells were treated with 0, 5, 10, and 20 µM Resv, respectively. Cell proliferation was analyzed by cell counting kit8 (CCK-8) assay. The level of caspase-3 was measured by Western blot. HL-60 cells were divided into control group, 20 µM Resv treatment group, and Resv+PTEN inhibitor SF1670 group. Cell apoptosis was determined by flow cytometry. Cell proliferation was assessed by EdU staining. RESULTS: Compared with peripheral blood mononuclear cell (PBMC), PTEN mRNA and protein levels were significantly decreased in NB-4 and HL-60 cells. Resv significantly inhibited the proliferation activity in HL-60 and NB-4 cells, and increased the activity of caspase-3. Resv treatment up-regulated the expression of PTEN and reduced the expression of p-AKT protein in HL-60 cells. However, Resv treatment markedly suppressed the proliferation of HL-60 and induced apoptosis. SF1670 treatment in the presence of Resv significantly antagonized the down-regulation of p-AKT protein expression induced by Resv, resulting in decreased apoptosis and enhanced cell proliferation. CONCLUSIONS: Resv can up-regulate PTEN expression and inhibit the activity of PI3K/AKT pathway to play an anti-leukemia effect through suppressing cell proliferation and inducing apoptosis.

[Clinical strategy on repair of pressure injury on ischial tuberosity based on the histopathological type].

Objective: To investigate effects of clinical strategy on repair of pressure injury on ischial tuberosity based on the histopathological type. Methods: From January 2014 to January 2018, 33 patients with 33 pressure injuries on ischial tuberosity were admitted to our department. There were 25 males and 8 females aged 35 to 87 years. Pressure injuries on ischial tuberosity were repaired with different methods according to pathological types of denatured tissue on basal parts of wounds and tissue defect volumes. Areas of wounds after thorough debridement ranged from 2.0 cm×1.0 cm to 14.0 cm×12.0 cm. Pressure injuries of necrosis type with tissue defect volumes of 6.5-9.5 cm(3) were sutured directly after debridement at the first stage. Tissue defect volumes of 3 patients with pressure injuries of granulation type ranged from 56.0 to 102.5 cm(3). According to situation around wounds, the above mentioned 3 patients were respectively repaired with posterior femoral Z-shaped reconstruction, posterior femoral advanced V-Y flap, and posterior femoral propeller flap. Tissue defect volumes of 5 patients with pressure injuries of infection type ranged from 67.5 to 111.0 cm(3). Among the patients, 2 patients were repaired with posterior femoral propeller flaps, 2 patients were repaired with posterior femoral advanced V-Y flaps, and 1 patient was repaired with posterior femoral Z-shaped reconstruction. Among patients with pressure injuries of synovium type, wounds of 14 patients with tissue defect volumes 6.4-9.5 cm(3) were sutured directly after debridement, and tissue defect volumes of another 8 patients were 97.0-862.5 cm(3). Among the 8 patients, 7 patients were repaired with gluteus maximus myocutaneous flaps and continued vacuum sealing drainage was performed for 7 to 14 days according to volume of drainage, and 1 patient was repaired with posterior femoral propeller flap. Areas of flaps or myocutaneous flaps ranged from 3.5 cm× 2.5 cm to 14.0 cm×12.0 cm. The donor sites of flaps were sutured directly. Operative areas after operation and healing of wounds during follow-up were observed. Results: The sutured sites of 33 patients connected tightly, with normal skin temperature, color, and reflux. During follow-up of 12 months, wounds of 25 patients healed well with no local ulceration, and 8 patients were admitted to our department again due to recurrence of pressure injuries on or near the primary sites. Pathological types of pressure injuries of the 8 patients were synovium types. After complete debridement, the tissue defect volumes were 336.8-969.5 cm(3,) wounds with areas ranged from 8.0 cm×7.0 cm to 14.0 cm×12.0 cm were repaired with gluteus maximus myocutaneous flaps or posterior femoral propeller flaps which ranged from 8.0 cm×7.0 cm to 14.0 cm×12.0 cm. Eight patients were discharged after wound healing completely. During follow-up of 12 months, operative sites of the patients healed well, with no recurrence. Conclusions: Appropriate and targeted methods should be chosen to repair pressure injuries on ischial tuberosity based on the pathological types. Direct suture after debridement is the first choice to repair pressure injury of necrosis type. Pressure injuries of granulation type and infection type can be repaired with posterior femoral propeller flap, Z-shaped reconstruction, or advanced V-Y flap according to situation around wounds. Gluteus maximus myocutaneous flap is the first choice to repair pressure injury of synovium type. In addition, recurrence-prone characteristics of pressure injury of synovium type should be taken into consideration, plan should be made previously, and resources should be reserved.

[Multimodal analgesic analgesia in patients with obstructive sleep apnea hypopnea syndrome with multiple planar surgery].

Objective:To observe the value of multimodal analgesia in patients with OSAHS undergoing multiplanar surgery.Method: A total number of 90 patients with obstructive sleep apnea hypopnea syndrome with tongue hypertrophy or hyperplasia of the root lymphoid tissue were collected. All patients underwent improved uvulatopharyngeal angioplasty (H-UPPP) and tongue root partial resection, or simultaneous tongue ablation at the same time, and they were randomly divided into two groups,45 patients in each group.In multi-modal analgesic group, the parrixibub sodium 40 mg were given intravenously 0.5 h before surgery, and oxygen budesonide aerosol inhalation therapy was given after surgery.Besides,sodium aescinate 10 mg was given intravenously 24, 48, 72 h after surgery,respectively.The control group did not do the above treatment. Both groups received 40 mg paradoxes sodium hydrostatic Bid for 4 days.To perform VAS on two groups of patients, uvula swelling time and first time to eat were recorded，and the symptoms of postoperative nausea and vomiting were observed.Result: The general conditions of the two groups of patients, including age, sex, body mass index, intraoperative blood loss, and operative time, were not statistically significant(all of the P>0.05). The scores of 24, 48, 72, 96 h VAS in multi-mode analgesic group were lower than those in control group after the operation of multi-mode analgesia, and the difference was statistically significant（P<0.05）.The duration of the swelling time of the uvula in the multi-mode analgesic group was significantly shorter than that in the control group, and the difference was statistically significant (5.44±0.88) d compared with (7.68±0.89) d (t=12.01, P<0.01);(30.1±7.3)h compared with (36.5±7.0) h,(t=4.25, P<0.01).

[Reliability and validity of the simplified Chinese version of the fecal incontinence quality of life questionnaire in the patients with fecal incontinence].

Objective: To develop the Chinese version of the fecal incontinence quality of life (FIQL) questionnaire, and to validate them in Chinese population. Methods: Our study included 52 cases recruiting from outpatients diagnosed with fecal incontinence in Peking Union Medical College Hospital, fecal incontinence in Beijing City nursing homes for the elderly, and patients received perineal repair surgeries who suffered from perineal laceration and laceration in in Peking Union Medical College Hospital from October 2013 to 2016 December.The Original English Fecal Incontinence Quality of Life scale questionnaires were translated into Chinese and they were linguistically validated following the Cross-cultural adaptation of health-related quality of life measures.The reliability and validity of the Chinese version of FIQL questionnaires in Chinese population were evaluated. Results: Fifty-two patients completed the FIQL and the SF-12 questionnaires, as well as Cleveland Clinic Incontinence Score.The Cronbach's alpha of FIQL was 0.949, test-retest reliability ICC was 0.437-0.866. FIQL scores were positively correlated with SF-12 (Spearman correlation coefficient was 0.588, P<0.01) and negatively correlated with Cleveland Clinic Incontinence Score (Spearman correlation coefficient was -0.617, P<0.01). Factor analysis showed that there were 6 common factors in FIQL. Conclusions: Chinese version of FIQL have high reliability and validity in Chinese population, there fore it is suitable for clinic and research.

[Development and validation of the Chinese version of modified body imgae scale in Chinese population].

Objective: To develop the Chinese version of modified body image scale (MBIS) questionnaires, and to validate them in Chinese population. Methods: The original English MBIS questionnaire was translated into Chinese, following the WHO cross-cultural adaptation of health-related quality of life measures. The reliability and validity of the Chinese version of MBIS questionnaires were evaluated in Chinese population, MRKH syndrome patients. Results: Totally 50 patients with MRKH syndrome completed the MBIS and short-form 12-item health survey (SF-12) questionnaires. The Cronbach's alpha of MBIS was 0.741, intraclass correlation coefficients were 0.472-0.815 (P<0.01). MBIS scores were positively correlated with SF-12 scores (Spearman correlation coefficient was-0.409, P<0.01) . Factor analysis showed that MBIS had one common factor. Conclusion: Chinese version of MBIS has high reliability and validity in Chinese population, therefore is suitable for clinic and research.
