ABSTRACT

【Objective】 To investigate the knowledge acquisition status for blood transfusion of transfusion related medical staff in underdeveloped cities in western China and explore its influencing factors. 【Methods】 A questionnaire consisted of blood transfusion laws and regulations, clinical blood transfusion theory and blood transfusion technology was designed, randomly distributed to medical staff and blood transfusion departmenttechnicians of 17 secondary/tertiary hospitals in Wuwei and then collected on the spot. The knowledge acquisition of blood transfusion of each group was compared using statistical description method, and its influencing factors were analyzed by multivariate logistic regression analysis. 【Results】 A total of 507 questionnaires were issued, and 498 valid questionnaires (98.22%) were collected. The scores of transfusion related laws and regulations, blood transfusion theory and blood transfusion technology of doctor group(n=158), nurse group(n=239) and transfusion technician group(n=101)were 4.56-5.97(5.06±0.73)(P<0.01) vs 4.23-5.87(4.98±1.24)(P<0.01) vs 3.71-0.78 (4.15±1.34), 3.67-5.02(4.27±1.02) vs 3.76-5.12(4.06±0.75) vs 4.71-5.98(5.16±0.64)(P<0.01) and 3.41-5.76(3.82±0.56) vs 3.78-5.24(4.01±0.56) vs 3.77-5.46(3.82±0.59). Among the seven departments, blood transfusion department(n=51) won the highest score of above three types of knowledge [4.91-5.97(5.28±0.43) vs 5.03-5.92(5.36±0.59) vs 4.39-5.77(4.97±0.79)(P<0.01) ]. Univariate logistic regression analysis showed that age, occupation, professional titles, training times and hospital grade had an impact on the degree (score) of blood transfusion knowledge acquisition (P<0.05), and multivariate unconditional logistic regression analysis indicated that training times was an important influencing factor(P<0.01). 【Conclusion】 This survey revealed that the level of knowledge acquisition for blood transfusion among medical staff in Wuwei is generally low, and there is a significant difference between staff from hospitals of different grade and different departments. It is urgent to strengthen the training of blood transfusion for medical staff in western China.

ABSTRACT

Objective:To investigate the regulatory effects and mechanism of mannose-binding lectin(MBL) on autophagy during the differentiation of 3T3-L1 adipocytes, and provide the feasibility for targeting autophagy to prevent obesity and related pathological conditions in natural immunity.Methods:3T3-L1 preadipocytes were cultured in vitro and induced to differentiation. Cell differentiation and lipid accumulation were analyzed by oil red O staining and CCK-8 was used to detect the effect of different concentrations of MBL (0, 1, 5, 10 μg/ml) on cell proliferation ability at different differentiation stages. Western blot was used to analyze the expression of MBL(10 μg/ml) on the key autophagy factors LC3B, Beclin1 and p62 protein at different stages of differentiation, and the changes of lipid droplet accumulation under the intervention of MBL were observed by oil red O staining. The protein and mRNA expression of autophagy key factors under the intervention of different concentrations of MBL were detected by Western blot and qRT-PCR. And autophagy flow analysis based on autophagic degradation was used to further illustrate the autophagic activity. The expression and phosphorylation of adenosine monophosphate-activated protein kinase(AMPK)/mammalian target of rapamycin(mTOR) signaling molecules were analyzed by Western blot. Results:The results of oil red O staining showed that 3T3-L1 preadipocytes could achieve complete differentiation after 10 days of induction. CCK-8 showed that the concentration of MBL (1-10 μg/ml) in the experimental group had no effect on cell proliferation at different differentiation stages. During the differentiation of 3T3-L1 preadipocytes, Western blot and qRT-PCR showed that the expression of autophagy-related proteins and mRNA levels was enhanced in the MBL treated group, and presented a concentration-dependent relationship. Oil red O staining showed that the lipid droplets in adipocytes at different stages of differentiation are reduced to varying degrees under the intervention of MBL. Fluorescence microscopy results further confirmed that MBL enhanced the autophagy activity of adipocytes by increasing the synthesis of autophagosomes. Moreover, under the intervention of MBL, the phosphorylation level of AMPK was significantly up-regulated, while the phosphorylation level of mTOR was significantly down-regulated, also showing a concentration-dependent relationship.Conclusions:MBL accelerates the autophagy process during the differentiation of 3T3-L1 adipocytes through AMPK/mTOR signaling pathway, reduces lipid accumulation, providing a possible functional pathway for the treatment of obesity and related metabolic diseases.

ABSTRACT

Background@#Interferon lambda receptor 1 (IFNLR1) is a type II cytokine receptor that clings to interleukins IL-28A, IL29B, and IL-29 referred to as type III IFNs (IFN-λs). IFN-λs act through the JAK-STAT signaling pathway to exert antiviral effects related to preventing and curing an infection. Although the immune function of IFN-λs in virus invasion has been described, the molecular mechanism of IFNLR1 in that process is unclear. @*Objectives@#The purpose of this study was to elucidate the role of IFNLR1 in the pathogenesis and treatment of porcine reproductive and respiratory syndrome virus (PRRSV). @*Methods@#The effects of IFNLR1 on the proliferation of porcine alveolar macrophages (PAMs) during PRRSV infection were investigated using interference and overexpression methods. @*Results@#In this study, the expressions of the IFNLR1 gene in the liver, large intestine, small intestine, kidney, and lung tissues of Dapulian pigs were significantly higher than those in Landrace pigs. It was determined that porcine IFNLR1 overexpression suppresses PRRSV replication. The qRT-PCR results revealed that overexpression of IFNLR1 upregulated antiviral and IFN-stimulated genes. IFNLR1 overexpression inhibits the proliferation of PAMs and upregulation of p-STAT1. By contrast, knockdown of IFNLR1 expression promotes PAMs proliferation. The G0/G1 phase proportion in IFNLR1-overexpressing cells increased, and the opposite change was observed in IFNLR1-underexpressing cells. After inhibition of the JAK/STAT signaling pathway, the G2/M phase proportion in the IFNLR1-overexpressing cells showed a significant increasing trend. In conclusion, overexpression of IFNLR1 induces activation of the JAK/STAT pathway, thereby inhibiting the proliferation of PAMs infected with PRRSV. @*Conclusion@#Expression of the IFNLR1 gene has an important regulatory role in PRRSVinfected PAMs, indicating it has potential as a molecular target in developing a new strategy for the treatment of PRRSV.

ABSTRACT

Objective:To investigate the regulatory effects and mechanism of mannan-binding lectin (MBL) on adipogenic differentiation of 3T3-L1 preadipocytes.Methods:3T3-L1 preadipocytes were induced to differentiate into adipocytes in vitro, and stimulated with different concentrations of MBL (0, 1, 10, 20 μg/ml). Firstly, changes in cell proliferation ability were detected by CCK-8. Then lipid accumulation was analyzed by Oil red O staining and intracellular triglyceride content determination. Further, the expression of adipogenic differentiation-related factors PPARγ and C/EBPα at protein and mRNA levels were detected by Western blot and qRT-PCR, respectively. Finally, Western blot was used to analyze the expression and phosphorylation of Akt, a signal molecule related to adipogenic differentiation. Results:MBL at the concentrations of 0, 1, 10 and 20 μg/ml had no effect on the proliferation of 3T3-L1 preadipocytes. The level of triglyceride in MBL treatment groups decreased in a dose-dependent manner on 3 d after 3T3-L1 preadipocyte differentiation. Results of Oil red O staining showed that the number of lipid droplets in MBL treatment groups reduced significantly, and the absorbance values also decreased significantly in a concentration-dependent manner. Western blot and qRT-PCR results showed that the expression of PPARγ and C/EBPα at both protein and mRNA levels in MBL treatment groups decreased significantly in a dose-dependent manner, and the phosphorylation level of Akt was significantly down-regulated as well.Conclusions:MBL regulates the adipogenic differentiation of 3T3-L1 preadipocytes via Akt signaling pathway.

ABSTRACT

BACKGROUND@#Pneumonectomy and sleeve resection are routine operations for the treatment of central non-small cell lung cancer (NSCLC), but some patients suffered of central NSCLC, whose pulmonary function is too poor to tolerate pneumonectomy, or the tumor involves the bronchus and pulmonary artery extensively,it is hard to perform bronchovascular sleeve lobectomy. The aim of this study is to assess the feasibility of lung autotransplantation in the treatment of central NSCLC.@*METHODS@#The clinical data of 3 cases with central NSCLC treated by lung autotransplantation was reviewed from December 2016 to December 2018. One patient underwent double sleeve resection of left upper lobe with end-to-end anastomosis of the bronchus. Because the resection of the pulmonary artery was too long to perfrom a tension-free anastomosis, the inferior pulmonary vein was cut off, then the left lower lobe was moved up for an anastomosis of the inferior pulmonary vein and the stump of the superior pulmonary vein. In the other 2 cases, left pneumonectomy was performed directly, and the upper left lobe was excised in vitro. The lower left lobe was reset to the chest after trimming and flushing and then the bronchus, pulmonary artery and pulmonary vein were anastomosed in turn.@*RESULTS@#The average operation time was 333 min, the average time of vascular occlusion was 86 min, the average blood loss was 450 mL, and the average hospital stay was 18.7 d; Perioperative complications included a case of bronchial obstruction, which improved after sputum aspiration through bronchofibroscope. The average follow-up period was 20 mon; One case died of cancer, one case had recurrence of anastomotic stoma and brain metastasis, one case had 4R lymph node metastasis (stable condition after chemotherapy), and one case survived without recurrence.@*CONCLUSIONS@#For patients with central NSCLC with extensive tumor invasion, thus inability to tolerate sleeve resection or pneumonectomy, autologous lung transplantation can preserve lung function to the greatest extent with a complete tumor resection and improve postoperative quality of life.

ABSTRACT

@#The precise resection and suture of bronchia, vascular and pulmonary tissue are the key techniques in thoracic surgery. Mechanical suture technique has gradually become a routine operation in thoracic surgery. However, at present, there is still a lack of consensus and guidelines on the application of this technique in thoracic surgery, neither strong evidence-based medical support. In this study, we discuss the application standard of mechanical suture technique in thoracoscopic surgery, irregular treatment techniques, intraoperative complications, and management principles to promote the standardized application of mechanical suture technique. We also explain the shortcomings of the technique in order to promote the further improvement and perfection.

ABSTRACT

OBJECTIVE@#To investigate the effect of orthodontic traction on the microstructure of dental enamel.@*METHODS@#Forty-eight isolated premolars were randomly divided into 6 groups (=8), including Group A (blank control group), in which the teeth were bonded with the orthodontic brackets without any loading force; Groups B1, B2, and B3 where the teeth were bonded with the orthodontic brackets using clinical adhesives and loaded with 50 g force for 6 months, 200 g force for 6 months, and 200 g force for 1 month, respectively; and Groups C1 and C2, where the teeth were bonded with straight wire brackets using light curing bonding and chemical curing bonding techniques, respectively. All the teeth were embedded with non-decalcified epoxy resin. Scanning electron microscope (SEM), atomic force microscope (AFM), and energy spectrometer (EDS) were used to analyze interface morphology and elemental composition of the teeth sliced with a hard tissue microtome.@*RESULTS@#Compared with those in Group A, the teeth in the other 5 groups showed increased adhesive residue index with microcracks and void structures on the enamel surface under SEM; AFM revealed microcracks on the enamel surface with angles to the grinding direction. A larger loading force on the bracket resulted in more microcracks on the enamel interface. The interface roughness differed significantly between Groups A and C2, and the peak-to-valley distance differed significantly between Groups A, C, and C2.@*CONCLUSIONS@#Orthodontic traction can cause changes in the microstructure of normal dental enamel.

ABSTRACT

Objective@#To understand the current situation of intimate partner violence (IPV) among young students in Chengdu and its relationship with emotion regulation self-efficacy,and to provide a reference for conducting the education on close relationship.@*Methods@#Totally 1 041 young students with love experience in Chengdu were selected by by stratified cluster random sampling to explore potentional factors related to IPV.@*Results@#The incidence of IPV perpetration among young students with love experience was as high as 69.6% and the incidence of IPV victimization was 62.2%. Young students had committed(65.4%) or been subjected(64.0%) to more than three intimate partner violence. 59.92% young students were both perpetrators and victims of IPV. Multiple Logistic regression analysis showed that compared with young female students, young male students were not prone to commit violence in intimate relationships(OR=0.59), but may become victims of IPV(OR=1.91). More than half a year in love(OR=1.70), cohabitation(OR=2.47), bullying by peers (OR=1.54) and interference by parents (OR=1.63) were risk factors for IPV perpetration. Among them, more than half a year in love (OR=1.51) and cohabitants (OR=2.52) were positively associated with IPV victimization. The efficacy of managing negative emotions was a negatively associated with IPV perpetration (OR=0.96) and victimization(OR=0.97)(P<0.05).@*Conclusion@#The phenomenon of intimate partner violence among young students is more common, which is closely related to the rearing style of young students, peer relationship, love relationship and the ability to manage negative emotions, which should be paid attention to.

ABSTRACT

Objective@#To analyze the decline of activities of daily living (ADL) ability and influencing factors over a period of 2 years in community-dwelling older adults in China.@*Methods@#The study subjects were from the project of Prevention and Intervention on Neurodegenerative Disease for Elderly in China of 2015-2017 to select the samples. In 2015, a total of 23 803 community- dwelling residents adults, aged ≥60 years old, came from both urban and rural areas, were selected through a stratified multi-stage cluster sampling in 6 provinces and joint baseline survey. The follow-up was conducted in 2017 to collect the related information using the same questionnaires and examinations. Finally, 18 785 elderly people were included in this analysis after excluding those who were died, failed to follow up, had incomplete data cases or defined as ADL disability at baseline survey. The post-stratification weight on the sample data was done by using the 6th national population census data as the standard, the rates of ADL/basic activities of daily living (BADL)/instrumental activities of daily living (IADL) disabilities over 2 years were calculated and compared among the elderly with different characteristics. Multiple logistic regression models were used to analyze the factors associated with BADL/IADL disabilities.@*Results@#During the 2-year follow-up, ADL disability developed in 1 959 participants with a rate of 12.0% (1.6% for BADL disability and 10.4% for IADL disability only). Multivariate logistic regression analysis showed that the risk factors for BADL disability included increased age, obesity, comorbidity and cognitive impairment. The risk factors for only IADL disability included increased age, being female, lower weight and cognitive impairment. Compared with illiterates, the educated had lower risk for only IADL disability. Compared with those with normal weight, overweight and obese old people had lower risk for only IADL disabilities.@*Conclusion@#Increased age and cognitive impairment were associated with the increased risk for BADL and IADL disabilities. Older people with comorbidities had higher risk for BADL disability. Obesity increased the risk of BADL disability, but decreased the risk for IADL disability in older people. Women had a higher risk for IADL disability compared with men. Being educated was associated with lower risk of IADL disability.

ABSTRACT

Objective@#To investigate the disability status and its epidemiological characteristics in the elderly in urban and rural communities in China.@*Methods@#The participants were from the project of Prevention and Intervention on Neurodegenerative Disease for Elderly in China conducted in 2015. A total of 23 803 urban and rural residents aged over 60 years were selected through stratified multi-stage cluster sampling in 6 provinces for a set of standardized questionnaire interview and physical examinations. Activities of daily living (ADL) scale was used to assess the disability status of the elderly. χ2 test was used to analyze the difference in basic activities of daily living (BADL) and instrumental activities of daily living (IADL) disabilities in different elderly populations. Multivariate logistic regression model was used to analyze the influence factors for disability.@*Results@#Taking bath had the highest impairment rate (1.7%) while eating had the lowest impairment rate (0.6%) in BADL. Making phone call had the highest impairment rate (16.6%), followed by taking bus (5.5%) and taking medicine (1.8%) in IADL. The BADL and IADL disability rates in community seniors were 2.1% and 19.1%, respectively. BADL disability rate was higher in females, the widowed, illiterate, the elderly with low body weight or obesity (P<0.05). IADL disability rate was higher in females, rural residents, the widowed, the elderly with lower educational level or lower body weight (P<0.05). Multivariate analysis showed that risk for BADL disability increased with age and abnormal BMI, and decreased with the increase of education level. The risk factors for IADL disability included being female, age, rural residence, being widowed and low BMI. The risk for IADL disability was lower in those with higher education level and overweight or obesity.@*Conclusion@#The present study showed that the disability rate was high in the elderly in China, which was influenced by the aging and multi demographic characteristics of the elderly. It is important to strengthen the prevention of BADL and IADL disabilities and intervention in the elderly.

ABSTRACT

Objective@#To quantify the effects of short-term walking intervention on body mass index (BMI), waist circumference, and related indicators of working population.@*Methods@#The China Motivational Healthy Walking Program in 2016 recruited 29 224 individuals from 139 demonstration areas for comprehensive prevention and control of chronic and non-communicable diseases at the national level and 70 areas at the provincial level. All subjects volunteered to participate into this program. The intervention lasted 100 days from June to September 2016. The walking behavior, height, weight and waist circumference of subjects were measured using a uniform pedometer, body composition tester, height tester and waist-to-hip caliper before and after the intervention. Daily average steps, daily average effective steps, and the percent of fulfilling continuous walking per day were used as main indicators in this study. Self-administered questionnaires were used to collect demographic characteristics, behaviors and chronic diseases. With the adjustment of potential confounding factors, multilevel regression was used to quantify the effect of walking on BMI and waist circumference, and multilevel logistic regression was used to quantify the effect on overweight or obesity and central obesity.@*Results@#A total of 12 368 subjects completed walking interventions and all measurements included in this study. The mean±SD age of all subjects was (41.19±8.99) years, and 5 155 (59.17%) of them were women. After 100-day intervention, all outcome variables decreased significantly. For every additional 1 000 steps per day, subjects would have extra decrease in BMI of 0.023 kg/m2 [β (95%CI): -0.023 (-0.030, -0.017)], in waist circumference of 0.046 cm [β (95%CI): -0.046 (-0.071, -0.020)], and the likelihood for becoming overweight or obesity was 0.97 times [OR (95%CI): 0.97 (0.95, 0.98)] that of before intervention. With additional 1 000 effective steps per day, the difference between baseline and endpoint increased by 0.028 kg/m2 [β (95%CI): -0.028 (-0.035, -0.020)] in BMI and 0.062 cm [β (95%CI): -0.062 (-0.091, -0.033)] in waist circumference. The likelihood of progressing into overweight or obesity was 0.97 times [OR (95%CI): 0.97(0.95, 0.98)] that of before-intervention, and the likelihood of becoming central obesity was 0.98 times [OR (95%CI): 0.98(0.96, 0.99)] that of before-intervention. Compared to subjects with low level percent of fulfilling continuous walking per day, those with high level would have an extra decrease in BMI by 0.150 kg/m2 [β (95%CI): -0.150 (-0.22, -0.079)], in waist circumference by 0.340 cm [β (95%CI): -0.340 (-0.620, -0.064)], and the likelihood of becoming overweight or obesity decreased to 0.74 times that of the low level group [OR (95%CI): 0.74(0.62, 0.89)] and the likelihood of becoming central obesity decreased to 0.78 times that of the low level group [OR (95%CI): 0.78 (0.68, 0.91)].@*Conclusion@#Strengthening walking exercise in the short term has a positive effect on promoting working population to reduce BMI and waist circumference, and prevent overweight, obesity and central obesity.

ABSTRACT

Objective@#To examine the effects and associated factors of the China Motivational Healthy Walking Program among occupational population.@*Methods@#The 2016 China Motivational Healthy Walking Program recruited 29 224 participants from 139 demonstration areas for comprehensive prevention and control of chronic and non-communicable disease at national level and 70 at provincial level. Intervention on walking was carried out by adopting group and individual motivating measures. Walking steps were recorded by electronic pedometer. We used percent of days achieving 10 000 steps (P10 000), percent of days fulfilling continuous walking (PCW), and proportion of valid walking (PVW) steps to reflect walking quantity, pattern and quality of participants. Motivation intensity was measured by summing up scores of each motivating activity. Questionnaire-based online survey collected information about demographic characteristics, lifestyle risk factors and chronic diseases. This study finally included 12 368 individuals in the analysis. Multilevel logistic regression model was used to assess the effect of group and individual motivating measures on walking activity and corresponding associated factors.@*Results@#Age of the study sample was (41.2±8.99) years, and 58.17% (7 194) of them were female. After 100-day intervention, the P10 000, PCW and PVW of all participants were 93.89%±14.42%,92.01%±15.97% and 81.00%±7.45%, respectively. The mean P10 000 and PCW increased with rising group-motivated scores, self-motivated scores and individual-activity scores (P<0.001 for all). The mean PVW decreased with both higher group-motivated scores and self-motivated scores (both P<0.05), and varied little among groups with different level individual-activity scores (P=0.525). According to the results from the multilevel model, those who had greater group-motivated scores and self-motivated scores tended to have more likelihood of high-level of P10 000 and PCW. Age, sex, smoking status, education attainment and alcohol drinking were associated with P10 000 and PCW (P<0.05 for all).@*Conclusion@#The Motivational Healthy Walking Program had positive effect on promoting healthy walking among occupational population. Group-motivated and self-motivated activities were associated with healthy walking.

ABSTRACT

Objective To investigate the epidemiological characteristics of obesity and its relationships to five common chronic diseases among the Chinese elderly population.Methods In 2013,The 4th Chronic Non-communicable Disease & Risk Factor Surveillance in China was conducted in 31 provinces.A multistage cluster sampling method was used at 298 National Disease Surveillance Points(DSPs).A total of 51778 adults aged 60 and over received a standardized questionnaire,physical examinations,and laboratory tests for blood lipid & glucose levels.The body mass index(BMI)was used for obesity measurement and waist circumference(WC)for central obesity measurement.After weighting adjustment of the sample,the prevalence of obesity and central obesity was compared between different genders,among different age groups,and among different regions.The unconditional Logistic regression model was applied to analyze the relationships of five selected chronic diseases with BMI and WC.Population attributable fractions (AFP)were also calculated.Results Among the elderly,the prevalence of obesity and central obesity was 13.2 % and 55.4 %,respectively.Both were higher in women(16.3% and 64.4%)than in men(9.9% and 46.0%)and higher in the urban areas (15.6% and 62.0%) than in the rural areas (12.0% and 52.1%) (all P < 0.05).The increased prevalence of five common chronic diseases was correlated with increased BMI and WC(all P<0.05).After adjustment for confounders,obesity was associated with increased prevalence of hypertension,diabetes,dyslipidemia,and stroke (ORs:1.43-2.68,AFP s:0.05-0.18);central obesity was associated with increased prevalence of the five chronic diseases (ORs:1.35-1.88,AFPs:0.16-0.33)Conclusions High prevalence of obesity and central obesity can be seen in aged women and the urban elderly population.Obesity and central obesity are both related to hypertension,diabetes,dyslipidemia,and stroke.Besides,central obesity is also associated with myocardial infarction.

ABSTRACT

Objective To investigate the effect of continuous blood purification (CBP) on peripheral blood monocyte membrane CD14 (mCD14) expression and inflammatory response in patients with traumatic sepsis Methods A retrospective case control study was conducted on the clinical data of 50 patients with severe sepsis after trauma treated between January 2015 and December 2016. There were 34 males and 16 females, with an average age of 45.37 years (range, 16-73 years). Patients were divided into CBP group (25 cases) and non-CBP group (25 cases) according to whether they agreed to receive CBP treatment. The peripheral blood samples were collected at 0, 12, 24, 48, and 72 hours after treatment, and the mCD14 and leukocyte elastase (HLE) expressions were detected by flow cytometry and by ELISA, respectively. The peripheral blood mononuclear cells were isolated from the two groups 24 h after treatment and cultured in vitro. The variations of mCD14 expression in mononuclear cells were measured at 4, 8, 12, 24, 48, and 72 h after stimulation with lipopolysaccharide (LPS). The expression levels of tumor necrosis factor (TNF) -a, interleukin (IL) -6, and IL-10 in mononuclear cells were detected by ELISA. Results At 12, 24, 48, and 72 hours after treatment, the leukocyte elastase levels in the two groups were lower than those before treatment (P < 0.01), and the decrease in CBP group was significantly greater than that of non CBP group(P<0.01). At 12, 24, 48, and 72 hours after treatment, the mCD14 levels in both groups were up-regulated before treatment (P <0.01), and the increase in CBP group was significantly greater than that of non CBP group (P < 0.01). The mCD14 expressions before treatment, 4 h after treatment, and 8 h after treatment in CBP group were all higher than those in non CBP group at the same time points. At 4, 8, 12, 24, and 48 hours after the re-stimulation with LPS on the mononuclear cells in both groups, the levels of TNF-α and IL-6 in CBP group were significantly higher than those in non-CBP group (P <0.01), and there was no significant difference in IL-10 levels between the two groups (P >0.05). Conclusions CBP treatment can increase monocyte mCD14 expressions through eliminating inflammatory factors and pro-inflammatory mediators and reducing HLE directly or indirectly in patients with traumatic sepsis. When the body is stimulated again, its anti-inflammatory response ability is markedly stronger than that of patients who have not received CBP treatment.

ABSTRACT

Objective To explore the outcomes of free flap from the radial artery superficial palmar branch (RASP) innervated by the lateral cutaneous nerve of the forearm for repairing the defects of finger pulp. Methods From April, 2013 to February, 2015, 20 fingers in 20 cases were treated with free flap from RASP innervated by the lateral cutaneous nerve of the forearm. The area of flap was from 1.8 cm×2.0 cm to 2.0 cm×4.0 cm. Postoperative fol-low up was done termly. Results All 20 flaps survived. All cases were followed-up for 7-20 months ( averag, 12 months). The flaps appeared well with good texture. The two-point discrimination was from 7 mm to 12 mm, and grad-ed with S3 and S3+sensation. There was little scar noted at the donor site in the wrist. There was no influence of hand and wrist function. Conclusion The method of using free flap from SASP innervated by the lateral cutaneous nerve of the forearm to repair the defects of finger pulp has good clinical effect.
