ObjectiveTo discuss the impact of Buzhong Yiqitang on lipid metabolism in skeletal muscle of exercise-induced fatigue （EIF） mice through adiponectin receptor 1 （Adipor1）/adenosine 5'-monophosphate（AMP）-activated protein kinase （AMPK）/peroxisome proliferator-activated receptor gamma coactivator-1α （PGC-1α）. MethodC57BL6J mice were randomly divided into the control group， model group， low， middle， and high dose groups of Buzhong Yiqitang， and vitamin C group. No intervention was given to the control group， while the other groups were subjected to exhaustive swimming training to establish the EIF model. One hour before exhaustion， 0.2 mL distilled water was given to the control group and the model group， while the mice in the low， middle， and high dose groups of Buzhong Yiqitang were given intragastrically Buzhong Yiqitang of 4.1， 8.2， and 16.4 g·kg-1， respectively， and the vitamin C group was given vitamin C of 0.04 g·kg-1 via gavage for a duration of six weeks. After six weeks of the experiment， the growth rate of body weight， organ index， and exhaustive swimming time were calculated. Enzyme colorimetry was utilized to detect the levels of blood urea nitrogen （BUN）， creatine kinase acid （CK）， lactate dehydrogenase acid （LDH）， and lactic acid （LD）. The pathological changes of skeletal muscle were observed using hematoxylin -eosin （HE） staining， while the ultrastructure of skeletal muscle was observed with transmission electron microscope （TEM）. The contents of free fatty acids （NEFA） and triglyceride acid （TG） in serum were also examined by microplate method. The protein expressions of Adipor1， p-AMPK/AMPK， PGC-1α， and HK2 in the skeletal muscle were measured by Western blot. ResultCompared with those of the control group， the growth rate of body weight and thymus index of the model group were decreased， and the serum levels of BUN， CK， LD， and LDH were increased （P<0.01）. The contents of NEFA and TG were decreased （P<0.01）， and the protein expression of Adipor1， p-AMPK/AMPK， PGC-1 α， and HK2 in the skeletal muscle decreased （P<0.05， P<0.01）. Compared with those in the model group， the growth rate of body weight， thymus index， and exhaustive swimming time were significantly increased （P<0.01）， and the levels of BUN， CK， LD， and LDH dropped in the high dose group of Buzhong Yiqitang （P<0.01）. The levels of NEFA and TG were greatly improved （P<0.01）. The protein expressions of Adipor1， p-AMPK/AMPK， PGC-1α， and HK2 in the skeletal muscle were significantly increased （P<0.05， P<0.01）. Compared with those in the model group， the thymus index and exhaustive swimming time were significantly increased in the vitamin C group， and the levels of BUN， CK， and LD dropped （P<0.05， P<0.01）. The levels of NEFA and TG were improved significantly （P<0.01）， and the protein expression of Adipor1 in skeletal muscle was increased greatly （P<0.01）. ConclusionBuzhong Yiqitang can delay the development of EIF， which may be connected with the regulation of the Adipor1/AMPK/PGC-1α signaling pathway and the improvement of the utilization rate of skeletal muscle to fat.

Objective: To compare the efficacy of intravascular ultrasound (IVUS) and coronary angiography guided drug eluting stent (DES) implantation for the treatment of left main coronary artery (LMCA) lesions. Methods: Randomized controlled trials (RCT) and observational studies, which compared IVUS with coronary angiography guided DES implantation for the treatment of LMCA lesions published before August 2021 were searched in PubMed, Embase and Cochrane Library databases. Baseline data, interventional procedures and endpoint events of each study were collected. The primary endpoint was major cardiovascular adverse events (MACE), and the secondary endpoints were all-cause death, cardiac death, myocardial infarction (MI), target lesion revascularization (TLR) and target vessel revascularization (TVR). The Newcastle-Ottawa Scale (NOS) and the Cochrane Collaboration Risk of Bias tool were used to evaluate the quality of the included studies. Results: Nine studies were included, including 3 RCT and 6 observational studies, with a total of 5 527 cases of LMCA. All the 6 observational studies had NOS scores≥6, and the 3 RCT had a low risk of overall bias. The results of meta-analysis showed that compared with coronary angiography guided group, MACE rate (OR=0.55, 95%CI 0.47-0.66, P<0.001), all-cause death (OR=0.56, 95%CI 0.43-0.74, P<0.001), cardiac death (OR=0.43, 95%CI 0.30-0.61, P<0.001), MI (OR=0.64, 95%CI 0.52-0.79, P<0.001), TLR (OR=0.49, 95%CI 0.28-0.86, P=0.013) and TVR (OR=0.77, 95%CI 0.60-0.98, P=0.037) were all significantly lower in the IVUS guided group. Conclusions: Compared with angiography guided, IVUS guided PCI with DES implantation in LMCA lesions could significantly reduce the risk of MACE, death, MI, TLR and TVR. IVUS is thus superior to coronary angiography for guiding PCI treatment among patients with LMCA.

Body mass index (BMI) has been increasing globally in recent decades. Previous studies reported that BMI was associated with sex hormone levels, but the results were generated via linear regression or logistic regression, which would lose part of information. Quantile regression analysis can maximize the use of variable information. Our study compared the associations among different regression models. The participants were recruited from the Center of Reproductive Medicine, The First Hospital of Jilin University (Changchun, China) between June 2018 and June 2019. We used linear, logistic, and quantile regression models to calculate the associations between sex hormone levels and BMI. In total, 448 men were included in this study. The average BMI was 25.7 (standard deviation [s.d.]: 3.7) kg m-2; 29.7% (n = 133) of the participants were normal weight, 45.3% (n = 203) of the participants were overweight, and 23.4% (n = 105) of the participants were obese. The levels of testosterone and estradiol significantly differed among BMI groups (all P < 0.05). In linear regression and logistic regression, BMI was associated with testosterone and estradiol levels (both P < 0.05). In quantile regression, BMI was negatively associated with testosterone levels in all quantiles after adjustment for age (all P < 0.05). BMI was positively associated with estradiol levels in most quantiles (≤80th) after adjustment for age (all P < 0.05). Our study suggested that BMI was one of the influencing factors of testosterone and estradiol. Of note, the quantile regression showed that BMI was associated with estradiol only up to the 80th percentile of estradiol.

Objective: To investigate the effects of two-step retraction and en-masse retraction on tooth movement pattern of anterior teeth and posterior anchorage with clear aligners using three-dimensional finite element analysis. Methods: A finite element model of maxillary first premolar extraction case undergoing clear aligner treatment was established based on maxillofacial cone-beam CT data of a 24-year-old adult male with individual normal occlusion, who visited Department of Oral Surgery, Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine for impacted mandibular third molar in June, 2022. The initial tooth displacement of five anterior retraction protocols (two-step with canine retraction, two-step with incisor bodily retraction, two-step with incisor retraction-overtreatment, en-masse bodily retraction, and en-masse retraction-overtreatment) were evaluated. Results: Two step with canine retraction caused distal tipping of the canine and labial tipping of the incisors (0.18° for central incisor and 0.13° for lateral incisor). Two step with incisor retraction caused mesial tipping of the canine. In two step with bodily retraction protocol, uncontrolled lingual tipping was found in central incisor (0.29°) and lateral incisor (0.32°). In two-step with incisor retraction-overtreatment protocol, the movement pattern of the incisors didn't change, but the inclinations reduced to 0.21° and 0.18°. En-masse retraction caused distal tipping of the canine. In en-masse bodily retraction protocol, uncontrolled lingual tipping was also found in central incisor (0.19°) and lateral incisor (0.27°). In en-masse retraction-overtreatment protocol, the central incisor showed controlled lingual tipping (0.02°) and the lateral incisor showed palatal root movement (0.03° labial inclination). Posterior teeth exhibited mesial tipping in all five protocols. Conclusion: En-masse retraction with incisor overtreatment was beneficial to incisor torque control in clear aligner treatment.

OBJECTIVES@#Pregnancy stress is the psychological confusion or threat caused by various stress events and adverse factors during pregnancy. Pregnant women exposed to many stressors, they will be easy to produce bad mood and prenatal depression if they cannot adapt to their own changes. Prenatal depression is one of the major global public health problems, with a higher incidence in developing countries and a negative impact on the health of pregnant women and fetus. Resilience refers to pregnant women using their own positive psychological capital, can self-emotional adjustment and improve their ability to adapt to the response state. A better level of resilience can enable pregnant women to face various negative and adaptive problems positively. This study aims to investigate the relationship between pregnancy stress, resilience and prenatal depression through a mental health survey of pregnant women.@*METHODS@#A total of 750 pregnant women in a Grade A tertiary hospital in Urumqi were investigated by self-designed demographic questionnaire, Pregnancy Pressure Scale (PPS) and Patient Health Questionnaire-9 (PHQ-9), Connor-Davidson Resilience Scale (CD-RISC), and the levels of stress during pregnancy, prenatal depression and resilience were analyzed. Pearson correlation analysis was used to explore the correlation between the three. Bootstrap mediation effect test was used to test the mediation effect relationship among the three. If the mediation effect was confirmed, AMOS software was used to establish the mediation effect structural equation model to analyze the mediation effect among the three.@*RESULTS@#Among 750 respondents, 709 (94.53%) had mild or above pregnancy pressure, 459 (61.20%) had mild or above depressive symptoms and 241 (32.13%) had a good or above level of resilience. Pearson correlation analysis showed that prenatal depression was significantly positively correlated with pregnancy stress (P<0.01), prenatal depression and pregnancy stress were significantly negatively correlated with resilience (all P<0.01). Mediation effect test analysis showed that all the pathways were statistically significant (P<0.01). Mediation effect of resilience between pregnancy stress and prenatal depression was significantly found (95% CI 0.022-0.068, P<0.001). Pregnancy pressure negatively affected resilience (β=-0.38, P<0.01), and resilience negatively affected prenatal depression (β=-0.10, P<0.01). The mediation effect of resilience was 6.5%.@*CONCLUSIONS@#Pregnant women's pregnancy pressure, resilience and prenatal depression are significantly correlated, and the mediation variable resilience plays a partial mediating role in the impact of pregnancy pressure on prenatal depression. Pregnant women can reduce the incidence of prenatal depression and promote their physical and mental health by exercising their resilience.

Objective: To investigate the influence of light and heavy bite force on the mandibular movement trajectories, and the influence of bite force on virtual occlusal pre-adjustment of digital full crown. Methods: From October 2021 to March 2022, 10 postgraduate volunteers (3 males and 7 females, aged 22-26 years) were recruited from Peking University School and Hospital of Stomatology. Maxillary and mandibular digital models of the participants were obtained by intraoral scanning. Jaw relations were digitally transferred under heavy bite force and mandibular movement trajectories under light and heavy bite force were recorded by jaw motion analyser. Three mandibular markers were chosen, namely the mesial proximal contact point of the central incisor (incisal point) and the mesial buccal cusp tips of the bilateral first molars. The three-dimensional displacements of the markers under two kinds of bite force in the intercuspal position (ICP), the sagittal projection of the three-dimensional displacements in the protrusive edge-to-edge position, and the coronal projection of the three-dimensional displacements in the lateral edge-to-edge position of upper and lower posterior teeth were measured. Single-sample t-test was used to compare the three-dimensional displacements and the corresponding sagittal projection and coronal projection with 0, respectively. The left maxillary central incisor and left mandibular first molar were virtually prepared by the reverse engineering software. Then dental design software was used to design digital full crown using the copy method. The mandibular movement trajectories under light and heavy bite force were separately used to guide virtual occlusal pre-adjustment. The three-dimensional deviations (mean deviations and root mean square) between the lingual surface of the left maxillary central incisor or the occlusal surface of the left mandibular first molar and that of the natural tooth before preparation were calculated (light bite force group and heavy bite force group), and the differences between the two groups were compared by the paired t-test. Results: Under the two kinds of bite force, the three-dimensional displacements of the markers in the ICP were (0.217±0.135), (0.210±0.133) and (0.237±0.101) mm, respectively; the sagittal projection of the three-dimensional displacements of the markers in the protrusive edge-to-edge position were (0.204±0.133), (0.288±0.148) and (0.292±0.136) mm, respectively; the coronal projection of the three-dimensional displacements of the mesial buccal cusp tips of the bilateral first molars in the lateral edge-to-edge position were (0.254±0.140) and (0.295±0.190) mm, respectively. The differences between the above displacements and 0 were statistically significant (P<0.05). The results of occlusal pre-adjustment showed that the mean deviations of the lingual surface of the left maxillary central incisor in the light and heavy bite force groups were (0.215±0.036) and (0.195±0.041) mm (t=3.95, P=0.004), respectively. The mean deviations of the occlusal surface of the left mandibular first molar were (0.144±0.084) and (0.100±0.096) mm (t=0.84, P=0.036), respectively. Conclusions: Both the light and heavy bite force have an influence on the mandibular movement trajectories. Virtual occlusal pre-adjustment of prostheses with mandibular movement trajectories under heavy bite force can obtain morphology of lingual or occlusal surfaces closer to the natural teeth before preparation.

Objective:To explore the therapeutic characteristics of population with gout achieving treat-to-target (T2T) indicators through real-world research and evaluate their safety.Methods:A total of 3 287 patients diagnosed with gout by rheumatologists in 21 first-class tertiary hospitals in 10 provinces, municipalities, and autonomous regions in China from January 2015 to December 2021 were included in this polycentric cross-sectional study. The database included patients′ general information, disease characteristics, and clinical application of traditional Chinese and Western medicine treatment measures. SPSS and Excel software were used for data analysis. Frequency analysis, cluster analysis, and factor analysis were used to summarize the characteristics and rules of treatment measures for patients with gout who achieved the target after treatment. The occurrence of adverse events (AE) was recorded during treatment.Results:After treatment, 691 visits (7%) achieved the serum urate (SUA) target, and the most frequent use of urate-lowering therapy (ULT) was febuxostat, followed by benzbromarone. The most common treatment options were following: GroupⅠ: traditional Chinese medicine (TCM) decoction-TCM external treatment-physical exercise-proprietary Chinese medicine; GroupⅡ: ferulic acid-nonsteroidal anti-inflammatory drugs (NSAIDs); Group Ⅲ: allopurinol-sodium bicarbonate-benzbromarone; Group Ⅳ: glucocorticoid-colchicine; Group Ⅴ: febuxostat. A total of 5 898 visits (60%) chieved manifestations of joint pain VAS scores target, and the most frequently used drug to control joint symptoms was NSAIDs. The frequency of use of drugs to control joint symptoms were 2 118 times (usage rate reached 35.9%), while the frequency of ULT were 2 504 times (usage rate reached 42.5%), which was higher than the joint symptom control drug. The most common treatment options were following: Group Ⅰ: proprietary Chinese medicine-TCM decoction-TCM external treatment-physical exercise; Group Ⅱ: NSAIDs-colchicine hormones; Group Ⅲ: allopurinol, Group Ⅳ: benzbromarone; Group Ⅴ: febuxostat. A total of 59 adverse events occurred during treatment.Conclusion:The proportions of gout patients who reach target serum urate level & good control of joint symptoms are both very low, and ULT and anti-inflammatory prescription patterns are very different from international guidelines, so it is necessary to strengthen the standardized management of gout patients. At the same time, life intervention measures account for a certain proportion of the treatment plans for the T2T population, and further exploration is needed.

In order to further promote the reform of medical service price and strengthen the macro management of medical service price, the author constructed a calculation method for price adjustment space of medical service. This study was centered on two parameters of the historical base and the growth coefficient, to calculate the total amountof price adjustment. The historical base used the total revenue of medical services in the region from the previous year, and the growth coefficient was measured by two methods, the comprehensive indicator method and the consumer price index (CPI) reference method.Taking Suzhou, a national pilot city, as an example, the historical base in 2022 was 18 754 million yuan. By using the comprehensive indicator method, the annual growth coefficient was calculated to be 2.38%, and adjustment space of medical service price was 446.35 million yuan; According to the CPI reference method, the growth coefficient of Suzhou was 2.10%, and adjustment space of medical service price was 393.83 million yuan.The two methods for calculating the total amount each have their own advantages and disadvantages, and need to be further optimized and improved by drawing on the practical experience of reform in each pilot city.

With the rapid development of information technology and the change in military education policy in the new era, online teaching has gradually become one of the main approaches to implement the clinical medical education in military teaching hospitals. In this study, the online teaching was performed mainly by pre-recorded teaching, supplemented by online live teaching. Massive open online courses (MOOCs) and the seminar-style teaching were advocated to be used in advanced disciplines. The quality of online teaching was guaranteed through infrastructure provision, teacher arrangement, teaching preparation, teaching interactivity, after-class test, teaching evaluation, supervision, and summary of teaching, which ultimately achieved a good effect. The results of the two-way questionnaires of 26 teachers and 129 students showed that 23.26% (30/129) of students and 65.38% (17/26) of teachers believed that students' learning ability was insufficient. 34.88% (45/129) of students and 23.08% (6/26) of teachers thought that the existing technology could not meet the requirements of online teaching. 55.04% (71/129) of students and 69.23% (18/26) of teachers held the view that the effect of online teaching was inferior to face-to-face teaching. 28.68% (37/129) of students and 57.69% (15/26) of faculty asked for the return of face-to-face education. Therefore, it is necessary to strengthen the construction of smart classroom platforms, establish a well-developed online teaching quality evaluation system, and integrate various innovative teaching modes with the online teaching. In these ways, it is expected to optimize the online teaching of clinical medicine and achieve the goal of online teaching.

Objective:To investigate the effect of microbubbles combined with gentamicin on the clearance of bacterial biofilms and the healing of diabetic foot ulcers under low-frequency ultrasound.Methods:From July 2021 to June 2022, 27 patients with chronic diabetic foot ulcers complicated with infection were prospectively selected from the Trauma Center of the Second Affiliated Hospital of Chongqing Medical University. The patients were divided into low-frequency ultrasound + microbubbles + gentamicin ointment group, low-frequency ultrasound + microbubbles group, and gentamicin ointment group by using a random number table, with 9 patients in each group. The three groups were all treated with simple debridement by the same surgeon.Afterward, in the low-frequency ultrasound+ microbubbles+ gentamicin ointment group, the wounds covered by 4% microbubble suspension were firstly irradiated with low-intensity focused ultrasound for 5 min, and then evenly applied with gentamicin ointment. In the low-frequency ultrasound + microbubbles group, the wounds covered by 4% microbubble suspension were irradiated with low-intensity focused ultrasound for 5 min. The gentamicin ointment group was treated with gentamicin ointment evenly. The treatment lasted for 2 weeks, and secretions and tissue specimens were collected during and 2 weeks after the treatment, respectively. The general indexes of wound surface (including ulcer depth score, secretion exudation score, fresh granulation tissue growth score, and total index score), ulcer area, ulcer healing rate, as well as negative rate of secretion culture were compared among the three groups after treatment. Additionally, the structural changes in bacterial biofilms under a scanning electron microscope and colony count under a laser confocal scanning microscope were compared among the three groups after treatment.Results:No significant differences were found in the general datas among the three groups (all P>0.05). After treatment for 2 weeks, the overall general indexes showed statistically and significant differences among the three groups (all P<0.05). Each index score in the low-frequency ultrasound + microbubbles + gentamicin ointment group was lower than that in the low-frequency ultrasound + microbubbles group and the gentamicin ointment group (all P<0.05). There were no significant differences in overall ulcer area among the three groups ( P>0.05). The overall ulcer healing rate presented significant differences among the three groups ( P<0.05). The healing rate in the low-frequency ultrasound + microbubbles + gentamicin ointment group was higher than that in the low-frequency ultrasound + microbubbles group and the gentamicin ointment group (all P<0.05). The overall negative rates of secretion culture among the three groups were significantly different ( P<0.05), the negative rate in the low-frequency ultrasound + microbubbles + gentamicin ointment group was higher than that in the low-frequency ultrasound + microbubbles group and the gentamicin ointment group (all P<0.05). Scanning electron microscopy confirmed bacterial biofilm infection in the three groups before treatment. After treatment for 2 weeks, the biofilm formation in the low-frequency ultrasound + microbubbles + gentamicin ointment group reduced significantly, while the low-frequency ultrasound + microbubbles group and the gentamicin ointment group had little change compared with that before treatment. Significant differences were detected in total colony count among the three groups under the confocal microscope ( P<0.05). The colony count in the low-frequency ultrasound + microbubbles + gentamicin ointment group was lower than that in the low-frequency ultrasound + microbubbles group and the gentamicin ointment group (both P<0.05). Conclusions:Ultrasound microbubbles combined with gentamicin can clear bacterial biofilms and promote the healing of diabetic foot ulcers.

Christianson syndrome is a rare X-linked disease caused by mutations in the SLC9A6 gene. The clinical manifestations are male developmental delay, language disorder, seizures, mental retardation, ataxia, microcephaly and so on. Two cases of male children with Christianson syndrome were reported. The proband was 1 year and 11 months old. Clinical manifestations include microcephaly, global developmental delay, and seizures. The electroencephalogram showed that the central midline region of spikes and slow waves were emitted, and all exons sequencing detected a mutation in the SLC9A6 gene chrX: 135084373 [c.803+1(IVS6)G>A]. The proband′s brother was 4 years and 8 months old. The clinical manifestations were similar. The electroencephalogram showed spikes and spines in the Rolandic area on both sides. Slow waves and spiny slow waves were emitted. Magnetic resonance imaging suggested brain atrophy. The genetic verification results were consistent with the proband. The SLC9A6 gene c.803+1(IVS6) G>A splicing mutation was a pathogenic mutation in this family.

Objective:To observe any therapeutic effect of repeated transcranial direct current stimulation (tDCS) on rats modeling neuropathic pain and explore possible mechanisms.Methods:Forty adult male Sprague-Dawley rats were randomly divided into a normal group ( n=10), a sham operation group ( n=10), a treatment group ( n=10) and a sham treatment group ( n=10). A model of chronic constriction injury of the sciatic nerve was established in the latter two groups. Fourteen days after the modeling, the treatment group was given tDCS for 8 consecutive days, while the sham treatment group received sham stimulation, and the other 2 groups did not receive any intervention. Von Frey and hotplate tests were used to test the rats′ pain thresholds 1 day before, as well as 14 and 22 days after the surgery (i.e., 8 days after the end of the treatment). Spinal cord tissue samples were taken to detect the protein expressions of N-methyl-D-aspartic acid receptor 2B, gamma-aminobutyric acid receptor types A (GABA a-R) and B (GABA b-R) using western blotting. Results:On the 14th day after the operation the average 50% MWT and WTL values of the sham treatment and treatment groups had decreased significantly compared with the sham operation group. By the 22nd day the average 50% MWT and WTL values of the treatment group were significantly higher than those of the sham treatment group, but there was no significant change in the treatment group′s average WTL between the 21st and 22nd days. On the 22nd day after the operation the average NR2B-NMDA-R level of the sham treatment group were significantly higher than that of the sham operation group, while the average GABA a-R and GABA b-R levels were significantly lower. At the same time point the treatment group′s average NR2B-NMDA-R level had decreased significantly compared to the sham treatment group, while the average GABA a-R level had increased significantly. There was no significant difference in average GABA b-R level between the treatment group and the sham treatment group at that point. On the 22nd day there was also no significant difference in the average NR2B-NMDA-R level between the treatment group and the sham operation group. Conclusions:Repeated tDCS can effectively relieve neuropathic pain. The relief of hyperalgesia is more significant than that of mechanical allodynia. A possible mechanism may be the down-regulation of spinal NR2B-NMDA-R to normal levels and modest up-regulation of GABA a-R.

Objective:To compare the use of continuous constant negative pressure drainage and intermittent suction mode drainage in abdominal wall angioplasty to minimize the impact of complications.Methods:From May 2017 to August 2019, the Department of Medical Cosmetology and Plastic Surgery, Wuhan Third Hospital treated 76 female patients after expanded flap repair, aged 27-35 years, with an average age of 30.5±14.2 years, and 58 female patients after abdominal wall plasty, aged 38-55 years, with an average age of 47.8±7.8 years. They were divided into intermittent negative pressure drainage group and continuous negative pressure drainage group. The negative pressure values in different intervals were set according to the type of operation. The drainage volume, drainage time, incidence of hematoma, subcutaneous effusion, flap necrosis rate, primary wound healing rate and drainage related bleeding were recorded and compared between the two groups.Results:After expanded flap repair in 38 cases, flap necrosis occurred in 1 case and hematoma in 3 cases; After abdominal wall plasty in 29 cases, flap necrosis occurred in 0 cases and hematoma in 1 case. The primary healing of incision was higher ( P<0.05), the drainage volume was larger, but the drainage time was shorter ( P<0.05), and no bleeding related to drainage was observed. The effect of monitoring drainage was positively correlated with the effect of operation. Conclusions:Continuous and constant negative pressure drainage is related to the prognosis of patients undergoing expansion flap repair and abdominal wall plasty. It is helpful to improve the effect of plastic surgery and the quality of nursing work. It is an effective method for nursing management after plastic surgery.
