Objective: To explore the effect of improved V-Y advancement flap with major artery perforator on repairing several skin and soft tissue defects in whole body. Methods: From March 2015 to June 2017, 4 cases with pressure ulcer in sacrococcygeal region, 4 cases with pressure ulcer at ischial tuberosity, 2 cases with scalp and skull defects at occiput, 1 case with secondary wound after tumor resection in axillary region, and 2 cases with skin and soft tissue defects caused by other trauma were hospitalized, with disease duration ranging from 1 week to 6 months. Bones, blood vessels, or nerves were exposed in wounds of 11 cases. After debridement, wounds with area ranging from 5 cm×4 cm to 15 cm×12 cm were repaired by improved V-Y advancement flap with major artery perforator including occipital artery perforator, arteria glutaea perforator, intercostal artery perforator, and peroneal artery perforator, and the area of flap ranged from 11 cm×5 cm to 35 cm×20 cm. Distal end of flaps additionally carried 1 major artery perforator in 4 cases. Results: All flaps survived well without hemodynamic disorder, and wounds and donor sites healed well. During the follow-up for 3 to 18 months, the flaps were good in appearance with similar color and texture to normal skin around wound and without recurrence of rupture. Conclusions Compared with traditional V-Y advancement flap, the improved V-Y advancement flap with major artery perforator has the advantages of larger repair area, longer advance distance without tension, simple operation, and good appearance after operation, which is beneficial to clinical application.

Objective: To analyze clinical characteristics and wound repair methods and effects of patients with upper limb electric burns. Methods: Medical records of 136 patients with upper limb electric burn who met the inclusion criteria and hospitalized in our unit from January 2015 to March 2019 were retrospectively analyzed. Proportion in patients with electric burns in the same period, gender, age, admission time, categories, injury causes, injury voltage, burn area and depth of upper limb, simultaneous injury of both upper limbs, and early wound treatment measure of patients with upper limb electric burn were recorded. The main repair methods of each affected limb were classified and recorded. The overall efficacy of the patients was recorded, including postoperative wound complications and healing condition. The patients repaired with distal pedicled flaps and those with free flaps were followed up for 3 to 6 months. The survival rate of flaps were recorded, the function of affected limbs after operation was evaluated, and the satisfaction degree of patients was investigated by Curative Effect Score Table. The amputation rate, age, and burn area of upper limbs of patients caused by high-voltage and low-voltage electricity were compared. Data were processed with Wilcoxon rank sum test, chi-square test, or Fisher′s exact probability test. Results: (1) The number of upper limb electric burn patients accounted for 88.3% of 154 patients with electric burns hospitalized in the same period, including 117 males and 19 females, aged 1 year and 2 months to 72 years [(34±18) years], admitted 1 h to 48 d after injury, including 51 electricians, 32 rural migrant workers, 31 students and preschool children, and 22 patients belonging to other categories. Patients of the first two categories were mainly injured by work accidents, and those of the latter two categories mainly suffered from touching power source or power leakage. Among all the patients, 75 cases were injured by high-voltage electric burn, and 61 cases were injured by low-voltage electric burn, with burn area of upper limb from 0.2% to 16.0% [2% (1%, 5%)] total body surface area (TBSA) and area of wounds deep to bone from 0.2% to 15.0% [2% (1%, 5%)] TBSA. Two upper limbs in 54 cases were simultaneously injured, accounting for 39.7%. Early fasciotomy was performed for 73 limbs. (2) Thirteen affected limbs were treated with dressing change, 2 affected limbs were sutured directly after debridement, 56 affected limbs were repaired by skin grafting, 12 affected limbs were repaired by local flap, 45 affected limbs were repaired by distal pedicled flap, 22 affected limbs were repaired by free flap, and 40 affected limbs were amputated (accounting for 21.1%). (3) One case died of pulmonary infection, sepsis, and multiple organ failure after operation, and the rest patients were all cured. One case with avulsion of abdominal flap was repaired by skin grafting after dressing change. The anterolateral thigh flap in one case necrotized after transplantation, which was replaced by pedicled abdominal flap. Seven cases had small erosion on the pedicle or margin after transplantation of abdominal flap and were healed by dressing change. Six cases had local bruising at the distal end after transplantation of abdominal flap and were healed after conservative treatment such as hyperbaric oxygen. The other flaps survived well. (4) The survival rate of distal pedicled flap grafting was 97.8% (44/45), which was close to that of free flap grafting (95.5%, 21/22, P>0.05). The function recovery of affected limb after free flap grafting was better than that of distal pedicled flap grafting (Z=-3.054, P<0.01), but their satisfaction degree of patients was similar (Z=-0.474, P>0.05). (5) Patients with high-voltage electric burn had higher amputation rate, older age, and larger upper limb burn area than those with low-voltage electric burn (χ²=4.743, Z=-2.801, -6.469, P<0.05 or P<0.01). Conclusions Upper extremity electric burn often occurs in children, electricians, and rural migrant workers with high rate of amputation. Teachers and parents should strengthen safety education for children and manage power source of life well. Workers should improve safety awareness and operate standardly. Fasciotomy for relaxation should be performed for electric burn wound as soon as possible, and flap grafting can effectively repair wound after early debridement. The function recovery of affected upper limb repaired with free flap grafting is better.

OBJECTIVETo study the effect of compound Danshen dripping pills and atorvastatin on restenosis after abdominal aorta angioplasty in rabbits.

METHODSRabbit models of abdominal aorta restenosis after angioplasty were established and treated with saline (group A), compound Danshen dripping pills (group B), atorvastatin (group C), or compound Danshen dripping pills plus atorvastatin (group D). HE staining was used to determine the thickness of arterial intimal hyperplasia and assess the morphological changes of the narrowed artery. Immunohistochemistry was employed to detect the expression of nuclear factor-κB (NF-κB) and monocyte chemoattractant protein-1 (MCP-1).

RESULTSCompared with group A, the 3 treatment groups showed significant increased vascular cavity area and reduced intimal area and percentage of intimal hyperplasia (P<0.05). The vascular cavity area, intimal area and percentage of intimal hyperplasia levels differed significantly between group D and groups B and C (P<0.05). Immunohistochemistry showed a significant reduction of the expression rate of NF-κB and MCP-1 in the 3 treatment groups compared with group A (P<0.05), and the reduction was especially obvious in group D (P<0.05).

CONCLUTIONSCompound danshen dripping pills combined with atorvastatin produces better effects than the drugs used alone in inhibiting vascular smooth muscle cell proliferation in rabbits after abdominal aorta angioplasty possibly due to a decreased expression of MCP-1 as a result of NF-κB inhibition.

OBJECTIVETo study the expression levels of annexin A1 (ANXA1), GATA-3, and T-bet in T lymphocytes of peripheral blood in burned mice with sepsis at early stage, and to analyze their immune regulatory mechanisms.

METHODSSeven-hundred and eighty male mice of clean grade were divided into sham injury group (n=60, sham injured on the back by immersing in 37 ℃ warm water for 10 s), burn group (n=240, inflicted with 20% TBSA deep partial- thickness burn on the back by immersing in 100 ℃ hot water for 10 s), sepsis group (n=240, intraperitoneally injected with 6 mg/kg lipopolysaccharide), and burn+ sepsis group (n=240) according to the random number table. Mice of burn+ sepsis group were treated as that in burn group at first, and then they were treated as that in sepsis group. (1) Immediately after injury, six mice in sham injury group were selected to collect lymphocyte suspension of peripheral blood (1 tube each mouse) according to the random number table. According to the random number table, 6 mice of each of the other three groups were respectively selected at post injury hour (PIH) 12, 24, 48, and 72 for the collection of lymphocyte suspension from peripheral blood (1 tube each mouse). Each tube of cell suspension was equally divided into two parts. Fluorescein isothiocyanate (FITC)-labeled human anti-mouse CD4 monoclonal antibody and phycoerythrin (PE)-labeled human anti-mouse interferon-γ monoclonal antibody were added to one part of cell suspension to mark helper T lymphocyte 1 (Th1). FITC-labeled human anti-mouse CD4 monoclonal antibody and PE-labeled human anti-mouse interleukin-4 (IL-4) monoclonal antibody were added to the other part of cell suspension to mark Th2. The percentages of Th1 and Th2 were determined with flow cytometer, and the ratio of Th1 to Th2 was calculated. (2) According to the random number table, 18 mice in sham injury group were selected immediately after injury for the collection of lymphocyte suspension of peripheral blood (1 tube each mouse), and 18 mice of each of the other 3 groups were respectively selected at PIH 12, 24, 48, and 72 to collect the lymphocyte suspension of peripheral blood (1 tube each mouse). The mRNA expression levels of ANXA1, GATA-3, and T-bet were determined by real-time fluorescent quantitative reverse transcription-PCR. (3) Immediately after injury, 36 mice in sham injury group were selected to collect lymphocyte suspension of peripheral blood (1 tube each mouse) according to the random number table, and then 36 tubes of cell suspension were divided into 6 batches (6 tubes each batch). Each one of 6 kinds of antibody combinations: antibodies for labeling Th1 and Th2 in combination with PE-anthocyanin 7 labeled human anti-mouse ANXA1 monoclonal antibody, PE-anthocyanin 7 labeled human anti-mouse GATA-3 monoclonal antibody, and PE-anthocyanin 7 labeled human anti-mouse T-bet monoclonal antibody was added to 1 tube of cell suspension at each batch. According to the random number table, 36 mice of each of the other 3 groups were respectively selected at PIH 12, 24, 48, and 72 for the collection of lymphocyte suspension of peripheral blood (1 tube each mouse), and then 36 tubes of cell suspension at each time point were divided into 6 batches for marking with 3 kinds of surface markers of Th1 and Th2 (6 tubes each batch). Each one of above-mentioned 6 kinds of antibodies was added to 1 tube of cell suspension at each time point for each batch. The percentages of ANXA1, GATA-3, and T-bet positive cells in Th1 and Th2 were determined with flow cytometer. Data were processed with one-way analysis of variance, analysis of variance of factorial design, and SNK test. The relationship between the percentages of ANXA1 positive cell and the percentages of GATA-3 positive cell in Th1 and Th2, and mRNA expression level of ANXA1 and mRNA expression level of GATA-3 in lymphocytes were assessed by linear correlation analysis.

RESULTS(1) Compared with those in sham injury group immediately after injury, the percentages of Th1 and Th2 and the ratio of Th1 to Th2 of mice in burn group were significantly decreased from PIH 24 on, with P values below 0.05; the percentages of Th1 and Th2 and the ratios of Th1 to Th2 of mice in sepsis group and burn+ sepsis group were significantly decreased from PIH 12 on, with P values below 0.05. (2) Compared with those in sham injury group immediately after injury, the mRNA expression levels of ANXA1 and GATA-3 in lymphocyte of mice in burn group were significantly decreased from PIH 24 on, with P values below 0.05; the mRNA expression level of T-bet was significantly decreased at PIH 24 but significantly increased at PIH 48 and 72, with P values below 0.05. Compared with those in sham injury group immediately after injury, the mRNA expression levels of ANXA1 and GATA-3 in lymphocytes of mice in sepsis group were significantly decreased from PIH 12 on, and the mRNA expression level of T-bet was increased significantly from PIH 12 on, with P values below 0.05; the mRNA expression levels of ANXA1, GATA-3, and T-bet in lymphocytes of mice in burn+ sepsis group were significantly decreased from PIH 12 on, with P values below 0.05, reaching the nadir at PIH 72 (0.50±0.04, 0.45±0.03, 0.21±0.05, respectively). (3) A significant positive correlation was observed between ANXA1 mRNA expression level and GATA-3 mRNA expression level in lymphocytes of peripheral blood (r=0.862, P<0.05). (4) Compared with those in sham injury group immediately after injury, the percentages of ANXA1 and GATA-3 positive cellsin Th1 and Th2 of mice in burn group were significantly lowered from PIH 24 on, and the percentage of T-bet positive cells was significantly decreased at PIH 24, but it was increased from PIH 48 on, with P values below 0.05. The percentages of ANXA1 and GATA-3 positive cells in Th1 and Th2 of mice in sepsis group were continuously decreased from PIH 12 on, which were lower at most time points than those in sham injury group immediately after injury, with P values below 0.05. The percentages of T-bet positive cells in Th1 and Th2 of mice in sepsis group were significantly increased since PIH 12 as compared with those in sham injury group immediately after injury, with P values below 0.05. The percentages of ANXA1, GATA-3, and T-bet positive cells in Th1 and Th2 of mice in burn+ sepsis group were continuously lowered from PIH 12, with significantly statistical differences at most time points as compared with those in sham injury group immediately after injury, with P values below 0.05. (5) The percentages of GATA-3 positive cells in Th1 and Th2 were significantly positively correlated with those of ANXA1 (with r values respectively 0.747 and 0.787, P values below 0.05).

CONCLUSIONSThe expression levels of ANXA1, GATA-3, and T-bet were continuously lowered in burned mice with sepsis, and it may play an important role in Th1/Th2 balance switching to Th2 bias and immunosuppressive process.

Objective:To establish a nomogram model for individualized prediction of poor prognosis in patients with cirrhosis of esophagogastric variceal bleeding (EGVB), and verify its efficacy, so as to provide a scientific basis for the prevention and treatment of EGVB.Methods:The clinical data of 389 patients with cirrhosis of EGVB from January 2010 to December 2018 in Hangzhou Hospital of Zhejiang Medical and Health Group were retrospectively analyzed. All patients were followed up for 3 years, including 232 cases with poor prognosis (poor prognosis group) and 157 cases with good prognosis (good prognosis group). The general clinical data and laboratory results were compared between 2 groups. Receiver operating characteristic (ROC) curve was used to analyze the optimal cut-off value of poor prognosis factors in patients with cirrhosis of EGVB; multivariate Logistic regression analysis was used to analyze independent risk factors of poor prognosis in patients with cirrhosis of EGVB. A nomogram model to predict poor prognosis in patients with cirrhosis of EGVB was established with R language software 4.0 "rms" package. Internal validation of the nomogram model was performed using correction curves, and the prediction efficiency of the nomogram model was evaluated using decision curves.Results:The age, ascites rate, liver surface roughness rate, end-stage liver disease model score (MELD score), Child-Turcotte-Pugh score (CTP score), alanine aminotransferase (ALT), aspartate transaminase (AST), international standard ratio (INR) and total bilirubin (TBIL) in poor prognosis group were significant higher than those in good prognosis group: (62.48 ± 6.21) years old vs. (58.71 ± 5.93) years old, 51.29% (119/232) vs. 35.03% (55/157), 60.78% (141/232) vs. 42.03% (66/157), (13.89±1.93) scores vs. (11.32 ± 1.69) scores, (8.93 ± 0.77) scores vs. (7.46 ± 0.63) scores, (37.73 ± 5.21) U/L vs. (32.13 ± 5.03) U/L, (64.19 ± 11.31) U/L vs. (57.36 ± 10.29) U/L, 1.73 ± 0.41 vs. 1.61 ± 0.39 and (24.31 ± 2.63) μmol/L vs. (19.86 ± 2.17) μmol/L, the albumin, hemoglobin and serum sodium were significantly lower than those in good prognosis group: (36.21 ± 4.51) g/L vs. (39.12 ± 4.96) g/L, (86.31 ± 8.27) g/L vs. (92.28 ± 9.67) g/L and (136.58 ± 18.24) mmol/L vs. (141.21 ± 19.26) mmol/L, and there were statistical differences ( P<0.01 or<0.05). ROC curve analysis results show that the optimal cut-off values of age, MELD score, CTP score, albumin, ALT, AST, hemoglobin, INR, TBIL and serum sodium for predicting poor prognosis in patients with cirrhosis of EGVB were 55 years old, 14.20 scores, 9.30 scores, 35 g/L, 38 U/L, 67 U/L, 88 g/L, 1.90 scores, 25 μmol/L and 135 mmol/L, respectively. Multivariate Logistic regression analysis results showed that age≥55 years old, ascites, MELD score ≥14.20 scores, CTP score ≥9.30 scores, albumin<35 g/L and INR≥1.90 were independent risk factors for poor prognosis in patients with cirrhosis of EGVB ( HR = 1.528, 1.439, 1.637, 1.795, 1.521 and 1.596; 95% CI 1.165 to 1.891, 1.088 to 1.790, 1.308 to 1.966, 1.385 to 2.205, 1.262 to 1.780 and 1.259 to 1.933; P<0.05 or<0.01). To construct a nomogram model that integrates independent risk factors for poor prognosis in patients with cirrhosis of EGVB, the predictive power of the model was good (C-index 0.839, 95% CI 0.781 to 0.948). The corrected curve of nomogram model to predict poor prognosis in patients with cirrhosis of EGVB was close to the ideal curve; when the high risk threshold>0.02, nomogram model provided a significant additional clinical net benefit to predict poor outcome in patients with cirrhosis of EGVB, which was higher than the individual risk factors. Conclusions:The nomogram model based on age, ascites, MELD score, CTP score, albumin, INR and other independent risk factors that affect the high risk of poor prognosis in patients with cirrhosis of EDVB has great clinical value in screening and identifying high risk of poor prognosis in patients with cirrhosis of EDVB.

Six novel compounds,comprising three quinolones(1a,1b,and 2)and three flavanones(3-5),along with seven known analogs(6-13),were isolated from the 95％EtOH extract of the stems and leaves of Glycosmis craibii var.glabra.The structures of the new compounds were elucidated using HR-ESI-MS,UV,and 1D and 2D nuclear magnetic resonance(NMR)data analysis.The ab-solute configurations were determined through Mosher ester and electronic circular dichroism(ECD)spectral analysis.Compounds 2,6,9,and 10 demonstrated inhibition of nitric oxide(NO)production stimulated by lipopolysaccharide in BV-2 microglial cells,with IC50 values ranging from 13.5 to 20.1 μmol·L-1,comparable to the positive control,dexamethasone.

Objective:To investigate the safety and efficacy of individualized sunitinib schedule for patients with metastatic renal cell carcinoma (mRCC) according to the monitoring results of plasma drug concentration.Methods:The clinical data of patients with mRCC who received sunitinib treatment in our center from January 2014 to December 2020 were retrospectively analyzed, including 20 patients who underwent monitoring of plasma drug concentration (monitoring group), and 45 patients, matched by propensity score matching, received sunitinib but did not undergo monitoring of plasma drug concentration during the same period (unmonitored group). In the monitoring group, there were 12 males and 8 females. The mean age was 52.9 years, and ECOG score ≤1 in 16 cases (80%). Three patients were in the IMDC favorable-risk group, 15 patients were in the intermediate-risk group, and 2 patients were in the high-risk group. There were 18 cases of clear cell carcinoma and 2 cases of non-clear cell carcinoma, 5 cases of ISUP grade 1-2 and 11 cases of grade 3-4. In the unmonitored group, there were 31 males and 14 females. The mean age was 57.7 years, and 30 patients had ECOG score ≤1, 15 cases ≥2. There were 10 cases in IMDC favorable-risk group, 23 cases in intermediate-risk group, and 12 cases in high-risk group. Thirty-seven cases were clear cell carcinoma and 8 cases were non-clear cell carcinoma, 8 cases were in ISUP grade 1-2 and 28 cases in grade 3-4. There were no statistically significant differences between the two groups in the above parameters ( P>0.05). The monitoring group used the regimen of taking sunitinib for 4 weeks and stopping for 2 weeks (4/2 week) in the first cycle. The blood concentration of sunitinib was monitored before the first cycle and on days 4, 7, 10, 14, 21 and 28, and personalized medication plan was formulated according to the curve of the blood concentration. The 4/2 week scheme was adopted in the undetected monitoring group.The two groups were compared in the incidence of adverse events (AEs), progression-free survival (PFS), overall survival (OS), tumor treatment response and other clinical outcomes. Results:In the monitoring group, 90% (18/20) of patients receiving sunitinib had a steady-state plasma concentration of more than 150ng/ml, of which 10 patients (50%) had a plasma concentration of 150-200 ng/ml and 8 patients (40%) had a plasma concentration of more than 200 ng/ml. Meanwhile, all patients with plasma concentration higher than 150 ng/ml developed severe AEs (grade 3 and above) after treatment. The other two patients' plasma concentration were 100-150 ng/ml, and did not have severe AEs.All patients in the monitoring group received individualized medication schedule adjustment according to the plasma drug concentration and the occurrence point of severe AEs, ensuring that the peak plasma drug concentration was maintained at about 100-150 ng/ml. Among them, 6 patients were changed to take 2 weeks and stop for 1 week (2/1 week schedule), 4 patients were changed to take 10 days and stop for 5 days (10/5 d schedule), 7 patients were changed to take 7 days and stop for 3 days (7/3 d schedule), and 3 patients were changed to take 5 days and stop for 2 days (5/2 d schedule). The incidence of severe AEs significantly decreased from 90% (18/20) to 35% (7/20), and the difference was statistically significant ( P=0.003), while the incidence of grade 3 and higher AEs was 55.6% (25/45) in the standard group, which was statistically significant compared with the incidence of severe AEs before adjustment in the monitoring group ( P=0.006). Further analysis of the efficacy difference between the two groups showed that the overall objective response rate in the monitoring group (40%, 8/20) was higher than that in the standard group (20%, 9/45), although the difference was not statistically significant ( P=0.09). Median PFS and OS were significantly longer in the monitored group than in the standard group (PFS: 23 vs. 10 months, P=0.002; OS: not reached vs.25 months, P=0.005). Conclusions:The bioavailability of sunitinib is high in mRCC patients, which may lead to higher plasma drug concentration, adjustment of medication regimen based on blood concentration monitoring significantly improved patient safety and clinical outcomes. However, further validation by larger-scale, multi-center and prospective studies is needed.
