Objective To investigate the feasibility and clinical experience of kidney transplantation from donors with Marfan syndrome (MFS). Methods Clinical data of 2 recipients undergoing kidney transplantation from the same MFS patient were retrospectively analyzed and literature review of 2 cases was conducted. Characteristics and clinical diagnosis and treatment of kidney transplantation from MFS patients were summarized. Results The Remuzzi scores of the left and right donor kidneys of the MFS patient during time-zero biopsy were 1 and 2. No significant difference was observed in the renal arteriole wall compared with other donors of brain death and cardiac death. Two recipients who received kidney transplantation from the MFS patient suffered from postoperative delayed graft function. After short-term hemodialysis, the graft function of the recipients received the left and right kidney began to gradually recover at postoperative 10 d and 20 d. After discharge, serum creatinine level of the recipient received the left kidney was ranged from 80 to 90 μmol/L, whereas that of the recipient received the right kidney kept declining, and the lowest serum creatinine level was 232 μmol/L before the submission date (at postoperative 43 d). Through literature review, two cases successfully undergoing kidney transplantation from the same MFS donor were reported. Both two recipients experienced delayed graft function, and then renal function was restored to normal. Until the publication date, 1 recipient has survived for 6 years, and the other recipient died of de novo cerebrovascular disease at postoperative 2 years. Conclusions MFS patients may serve as an acceptable source of kidney donors. However, the willingness and general conditions of the recipients should be carefully evaluated before kidney transplantation. Intraoperatively, potential risk of tear of renal arterial media should be properly treated. Extensive attention should be paid to the incidence of postoperative complications.

Objective:To observe the effects of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor combined with rosuvastatin on lipid levels and short-term prognosis in patients with acute ischemic stroke, and to explore the optimal therapeutic regimen in terms of efficacy and safety, so as to provide a basis for clinical practice.Methods:Consecutive patients with acute cerebral infarction within 72 hours of onset and lipids≥2.6 mmol/L admitted to Xuzhou Central Hospital from April 2022 to March 2023 were included in the study, and the randomized numeric table method was used to divide them into 3 groups of different treatment regimens, group A (rosuvastatin 20 mg, once a day), group B (rosuvastatin 10 mg, once a day+alirocumab 75 mg, once 2 weeks) and group C (rosuvastatin 20 mg, once a day+alirocumab 75 mg, once 2 weeks). General baseline data, National Institutes of Health Stroke Scale score, modified Rankin Scale score on day 90 and the occurrence of adverse events and serious adverse events were collected from the 3 groups. The primary efficacy outcome was the degree of reduction in low density lipoprotein-cholesterol (LDL-C) from baseline on day 90. The secondary efficacy outcomes were recurrence rate and time to recurrence in stroke patients within 90 days,etc. The primary safety outcome was hepatic insufficiency (transaminase elevation≥3 times normal) within 90 days. The secondary safety outcomes were death due to stroke within 90 days and fatal and nonfatal myocardial infarction.Results:A total of 501 patients were included, 166 patients in group A, 167 patients in group B, and 168 patients in group C. The differences in the baseline data of the 3 groups were not statistically significant (all P>0.05). LDL-C was reduced from baseline on day 90 in groups A, B, and C, with the differences of -1.5 (-1.7, -1.4) mmol/L, -2.2 (-2.5, -2.1) mmol/L and -2.2 (-2.6, -2.1) mmol/L, respectively, with statistically significant differences among the 3 groups ( H=1.497, P<0.001); the differences between the group A and group B, and between the group A and group C, were statistically significant ( Z=-11.125, P=0.006; Z=-9.475, P=0.012), while the difference between the group B and group C was not statistically significant ( Z=1.650, P=0.946). The numbers of 90-day stroke recurrence cases (recurrence rate) in patients in the groups A, B, and C were 12 (7.2%), 4 (2.4%), and 5 (3.0%), respectively, without statistically significant difference among the 3 groups ( χ 2=5.773, P>0.05); the recurrence time of patients in the groups A, B and C was (43.0±7.4) d, (66.0±8.3) d and (62.2±5.6) d, respectively, and the differences among the 3 groups were statistically significant ( F=14.096, P=0.001). Compared with the group A, patients in the groups B and C had a prolonged time to stroke recurrence within 90 days ( Z=-3.108, P=0.002; Z=-2.871, P=0.004), whereas the difference in the time to stroke recurrence within 90 days between patients in the groups B and C was not statistically significant ( Z=0.397, P=0.692). The time to stroke recurrence within 90 days was positively correlated with the level of LDL-C on day 90 ( β=0.850, P=0.031). Ten patients (6.0%) in the group A developed hepatic insufficiency, 1 patient (0.6%) in the group B, and 9 patients (5.4%) in the group C. The differences among the 3 groups were statistically significant (χ 2=7.622, P=0.022); and the difference between the group B and group C was statistically significant ( P=0.011). The differences of secondary safety endpoints, death due to stroke within 90 days [1 case (0.6%) in the group A, 0 case (0) in the group B, and 1 case (0.6%) in the group C], fatal and nonfatal myocardial infarction within 90 days [3 cases (1.8%) in the group A, 1 case (0.6%) in the group B, and 1 case (0.6%) in the group C], were not statistically significant among the 3 groups (all P>0.05). Conclusions:In patients with acute ischemic stroke, PCSK9 inhibitor combined with rosuvastatin (both medium and high doses) significantly reduced LDL-C levels compared with baseline, and at the same time prolonged the time to stroke recurrence, reduced adverse effects such as hepatic insufficiency, and had a high degree of safety. PCSK9 inhibitor combined with medium-dose rosuvastatin had a better effect.

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative acute lung injury (ALI) in the pediatric patients undergoing living-related liver transplantation.Methods:Sixty pediatric patients of either sex, aged 4-24 months, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, with New York Heart Association (NYHA) class Ⅰ or Ⅱ, with Child-Pugh B or C, scheduled to undergo elective left external lobe piggyback living-related liver transplantation, were divided into 2 groups ( n=30 each) using a computer-generated table of random numbers: control group (group C) and TEAS group (group T). In group T, bilateral Zusanli (ST36), Neiguan (PC6), and Feishu (BL13) acupoints were stimulated with disperse-dense waves at the initial intensity of 0.5 mA and frequency of 2/15 Hz, the current intensity was gradually increased until local slight muscle shaking appeared, and continuous stimulation lasted for 30 min at a 30-min interval (a cycle) until the end of operation. TEAS was performed for 30 min at the same time every day up to 1 week after surgery. Stimulus locations in group C were selected at 0.5 cm lateral to the acupoints, and the electrodes with inert medium were attached to the location, with no effective current output from acupuncture treatment instrument. The peak inspiratory pressure, plateau pressure, and pulmonary compliance were recorded before skin incision (T 0), at 30 min after portal vein occlusion (T 1), at 1 h after portal vein opening (T 2), at the end of operation (T 3), and the difference between peak inspiratory pressure and plateau pressure was calculated. Blood samples from the jugular vein were collected at T 0-3 to determine the levels of plasma club cell protein 16 (CC16), surfactant protein D (SP-D), soluble receptor for advanced glycation end products (sRAGE), tumor necrosis factor-alpha (TNF-α), and interleukin-10 (IL-10) by enzyme-linked immunosorbent assay. Blood samples from the radial artery were collected at T 0-3 for blood gas analysis, PaO 2 and A-aDO 2 were recorded, and oxygenation index (OI) and respiratory index (RI) were calculated. The indwelling time of postoperative tracheal tube and length of ICU stay were also recorded. The lung injury was assessed and scored using ultrasound at 48 h after surgery. The occurrence of ALI within 1 week after operation was also recorded. Results:Compared with baseline at T 0, OI was significantly decreased, RI was increased, and plasma IL-10 concentrations were increased at T 2, 3, and the plasma concentrations of TNF-α, CC16, sRAGE and SP-D were increased at T 1-3 in both groups ( P<0.05). Compared with group C, OI was significantly increased, RI was decreased, the plasma concentrations of sRAGE were decreased, and the plasma concentrations of IL-10 were increased at T 2, 3, and the concentrations of plasma TNF-α, CC16 and SP-D were decreased at T 1-3, the indwelling time of postoperative tracheal tube and length of ICU stay were shortened, the ultrasound score of lung injury was decreased ( P<0.05), and no significant change was found in the incidence of ALI in group T ( P>0.05). Conclusions:TEAS can alleviate ALI in the pediatric patients after living-related liver transplantation.

Objective:To explore the efficacy and safety of different anti-platelet regimens in the treatment of high-risk non-disabling ischemic cerebrovascular events (HR-NICE) guided by point-of-care testing of CYP2C19 gene. Methods:A single-centre, prospective, randomised, open-label, and blinded endpoint design was uesd in the study. From July 2020 to January 2022, HR-NICE patients were enrolled in the Stroke Green Channel and Department of Neurology of Xuzhou Central Hospital, and all patients were scraped the buccal mucosa for screening for CYP2C19 loss-of-function allele carriers by point-of-care testing . Patients with intermediate metabolism were defined as those who carried 1 loss-of-function allele and patients with poor metabolism were those who carried 2 loss-of-function alleles. This study reduced the test turnaround time to 1 hour by using a fully automated medical polymerase chain reaction analyzer for a point-of-care test of CYP2C19 genotype. CYP2C19 loss-of-function allele carriers were divided according to the random number table method into the conventional treatment group (clopidogrel 75 mg, once a day), the ticagrelor group (ticagrelor 90 mg, twice a day) and the intensive dose group (clopidogrel 150 mg, once a day) separately combined with aspirin (100 mg, once a day) dual antiplatelet for 21 days. Baseline information, Acute Stroke Org 10172 Treatment Trial staging, 90-day modified Rankin Scale score, occurrence of adverse events and severe adverse events were collected for all the 3 groups. The primary efficacy outcome was new stroke within 90 days, and the primary safety outcome was severe or moderate bleeding within 90 days. Results:A total of 716 patients were included: 240 in the conventional treatment group, 240 in the ticagrelor group and 236 in the intensive dose group. There was no statistically significant difference between the 3 groups at baseline (all P>0.05). There were 26 cases (10.8%) with new stroke events in the conventional treatment group, 11 cases (4.6%) in the ticagrelor group and 4 cases (1.7%) in the intensive dose group, with statistically significant differences among the 3 groups (χ 2=19.28, P<0.05), and the differences between the conventional treatment group and the ticagrelor group (χ 2=6.59, P=0.010) and between the conventional treatment group and the intensive dose group (χ 2=16.83, P<0.001) were statistically significant, whereas the difference between the ticagrelor group and the intensive dose group was not statistically significant ( P>0.05). In the 3 groups, there was 1 case (0.4%) of severe bleeding in the conventional treatment group, 6 cases (2.5%) in the ticagrelor group and none in the intensive dose group, which showed statistically significant differences (χ 2=7.23, P<0.05), and there was statistically significant difference between the ticagrelor group and the intensive dose group ( P=0.030). Among the patients with intermediate CYP2C19 metabolism, there were 13 cases (13/158, 8.2%) with 90-day recurrent stroke in the conventional treatment group, 4 cases (4/153, 2.6%) in the ticagrelor group, and 0 case (0/159) in the intensive dose group, with statistically significant difference (χ 2=16.04, P<0.001), and the differences between the intensive dose group and the conventional treatment group were statistically significant (χ 2=13.64, P<0.001), whereas there was no statistically significant difference between the intensive dose group and the ticagrelor group ( P>0.05). In the patients with 90-day recurrent stroke in the intensive dose group, there was 0 case (0/159) with intermediate metabolism and 4 cases (4/77,5.2%) with poor metabolism, with statistically significant differences ( P=0.011), whereas there were no statistically significant differences in the conventional treatment group and the ticagrelor group ( P>0.05). Conclusions:Screening carriers of CYP2C19 loss-of-function alleles by point-of-care testing can quickly and precisely guide the treatment of patients with non-cardiogenic HR-NICE. An intensive clopidogrel dose of 150 mg, once a day combined with aspirin was effective in reducing stroke recurrence with less occurrence of any bleeding and adverse events, and patients with intermediate CYP2C19 metabolism may be the best population to benefit.

【Objective】 To discuss the practice of emergency recruitment of blood donors through TikTok by shooting short videos, and evaluate the recruitment effect. 【Methods】 The completed short videos about blood donor emergency recruitment were released by major media official accounts on TikTok on New Year′s Day, May Day and National Day in 2022. Blood collection data within 10 days before and after the release were collected, and data within 7 days after the release were selected as the experimental group and the same period in last year as the control group to compare the blood collection units, donation frequency, gender and age of blood donors. 【Results】 The units of daily blood collection was the largest on day 1 after the release of TikTok short video, which was 3 times that of the previous day, and then decreased day by day, until to the same level as before the release on day 7. The daily blood collection, the proportion of first-time blood donors, donors aged 26 to 55 years old in the experimental group were all higher than those of the control group, but the proportion of blood donors aged 18 to 25 years old was lower than that of the control group. There was no significant difference in gender between the two groups. 【Conclusion】 Releasing short videos of blood donor emergency recruitment through TikTok, with fast dissemination and wild audience, can increase the blood inventory in a short time and is worthy of promotion.

BACKGROUND: Red-cell transfusion is critical for surgery during the peri-operative period; however, the transfusion threshold remains controversial mainly owing to the diversity among patients. The patient's medical status should be evaluated before making a transfusion decision. Herein, we developed an individualized transfusion strategy using the West-China-Liu's Score based on the physiology of oxygen delivery/consumption balance and designed an open-label, multicenter, randomized clinical trial to verify whether it reduced red cell requirement as compared with that associated with restrictive and liberal strategies safely and effectively, providing valid evidence for peri-operative transfusion. METHODS: Patients aged >14 years undergoing elective non-cardiac surgery with estimated blood loss > 1000 mL or 20% blood volume and hemoglobin concentration <10 g/dL were randomly assigned to an individualized strategy, a restrictive strategy following China's guideline or a liberal strategy with a transfusion threshold of hemoglobin concentration <9.5 g/dL. We evaluated two primary outcomes: the proportion of patients who received red blood cells (superiority test) and a composite of in-hospital complications and all-cause mortality by day 30 (non-inferiority test). RESULTS: We enrolled 1182 patients: 379, 419, and 384 received individualized, restrictive, and liberal strategies, respectively. Approximately 30.6% (116/379) of patients in the individualized strategy received a red-cell transfusion, less than 62.5% (262/419) in the restrictive strategy (absolute risk difference, 31.92%; 97.5% confidence interval [CI]: 24.42-39.42%; odds ratio, 3.78%; 97.5% CI: 2.70-5.30%; P <0.001), and 89.8% (345/384) in the liberal strategy (absolute risk difference, 59.24%; 97.5% CI: 52.91-65.57%; odds ratio, 20.06; 97.5% CI: 12.74-31.57; P <0.001). No statistically significant differences were found in the composite of in-hospital complications and mortality by day 30 among the three strategies. CONCLUSION: The individualized red-cell transfusion strategy using the West-China-Liu's Score reduced red-cell transfusion without increasing in-hospital complications and mortality by day 30 when compared with restrictive and liberal strategies in elective non-cardiac surgeries.

Objective:To compare the effects of different anesthesia methods on perioperative lung injury in pediatric patients with biliary atresia undergoing living donor liver transplantation.Methods:Ninety-one American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ pediatric patients with biliary atresia, regardless of gender, aged 0-36 months, with cardiac function grade of Ⅰ or Ⅱ and Child-Pugh grade of B or C, undergoing elective living donor liver transplantation, were selected. According to the anesthesia method, the pediatric patients were divided into 3 groups: propofol-based anesthesia group (P group, n=30), sevoflurane-based anesthesia group (S group, n=30) and propofol-sevoflurane-based anesthesia group (PS group, n=31). Group P received intravenous infusion of 1% propofol 9-15 mg·kg -1·h -1. In group S, sevoflurane was inhaled and the end-tidal concentration was maintained at 2.6%-4.0%.In PS group, 1% propofol 9-15 mg·kg -1·h -1 was intravenously infused and sevoflurane was inhaled, maintaining an end-tidal concentration at 1.0%-2.5%. Remifentanil 0.1-1.0 μg·kg -1·min -1 was intravenously infused during operation for analgesia, and cisatracurium besylate 1-2 μg·kg -1·min -1 was intravenously infused to maintain muscle relaxation in three groups. Immediately after anesthesia induction (T 0), at 60 min after start of surgery (T 1), at 10 min of anhepatic phase (T 2), at 60 min after portal vein opening (T 3), and immediately after abdominal closure (T 4), the concentrations of serum Clara cell secretory protein 16 (CC16), surfactant protein (SP-D), soluble receptors for advanced glycation end products (s-RAGE), high mobility group protein B1 (HMGB1), tumor necrosis factor-alpha (TNF-α) and interleukin-1beta (IL-1β) were measured using enzyme-linked immunosorbent assay method, and lung compliance (Cdyn) was simultaneously recorded. At T 0-T 4 and 24 h after surgery (T 5), the arterial blood gas analysis was performed to calculate the oxygenation index (OI) and respiratory index (RI). Lung ultrasound scores (LUS scores) were assessed at 24 h before surgery and T 5. The occurrence of pulmonary complications was recorded within 7 days after surgery. The survival was observed for 6 months after surgery. Results:There were no statistically significant differences in serum concentrations of CC16, SP-D and s-RAGE concentrations and LUS scores at different time points between group S and group P ( P>0.05). Compared with S group and P group, the serum CC16 concentrations at T 3 and s-RAGE concentrations at T 3, 4 were significantly decreased, and the C and B scores were decreased at T 5 in PS group ( P<0.05). There were no statistically significant differences in the concentrations of serum HMGB1, IL-1β and TNF-α, Cydn and incidence of ALI/ARDS, pulmonary infection, pleural effusion, and atelectasis within 7 days after surgery among the three groups( P>0.05). The 6-month survival rate was 100% in the three groups. Conclusions:Propofol-sevoflurane-based anesthesia has a better efficacy in reducing perioperative lung injury than propofol-based anesthesia and sevoflurane-based anesthesia in the perioperative period of liver transplantation.

Objective:To explore the clinical features, etiologies and outcomes of unknown origin fever after simultaneous pancreas-kidney transplantation(SPK).Methods:From March 2015 to January 2020, clinical data were retrospectively reviewed for 120 SPK recipients.According to the definite evidence of fever, such as microbial culture, imaging findings or rejection, they were divided into three groups of free-fever(FF, n=41)and defined-fever(DF, n=47)and fever of unknown origin(FUO, n=32). The differences in general clinical features, surgical complications, laboratory tests and prognoses were compared.Logistic regression was employed for analyzing the risk factors of FUO and Kapla-Meier for survival analysis.And P<0.05 was deemed as statistically significant. Results:Multivariate analysis revealed that preoperative diabetic gastroenteropathy was an independent risk factor for unexplained fever.Significant differences existed between FUO and DF groups in leucocyte count[6.50(5.13, 7.36)vs.10.36(6.11, 12.97)×10 9/L], C-reactive protein(CRP)[11.75(6.25, 16.85)vs.35.00(16.30, 75.00)μg/ml], procalcitonin[0.13(0.06, 0.18)vs.0.19(0.11, 1.05)ng/ml]( P<0.001, P<0.001, P=0.025). As compared with DF group, 19 recipients in FUO group only received 1-2 antibiotics and there was a shorter course of treatment[13(40.6%)vs.32(68.1%), P=0.016]. For 6(18.7%)recipients after a diagnosis of FUO, clinical outcome was achieved with only NSAIDs.Length of stay was(48.72±19.51)days in FUO group versus(57.36±27.46)days in DF group and the difference was statistically significant( P<0.001). Hospitalization expenses of two groups were 253 463.25 and 334 605.96 yuan respectively and the difference was also statistically significant( P=0.002). Conclusions:Diabetic gastroenteropathy is an independent risk factor for early FUO after SPK transplantation.Inflammatory markers of leukocytes, CRP and procalcitonin in FUO patients are significantly lower than DF group.And these clinical features can help diagnose FUO in an early stage.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

Objective:To determine the characteristics of changes in postoperative early lung ultrasound imaging in pediatric patients undergoing living-related liver transplantation.Methods:A total of 96 pediatric patients of both sexes, aged 3-24 months, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, with Child-Pugh grade B or C, scheduled for elective living-related liver transplantation performed with the piggy back technique, were selected.At 24 h before surgery (T 0), at 24 h after surgery (T 1) and at 72 h after surgery (T 2), the condition of lung ultrasound was recorded.Ultrasound examination was performed using Color Doppler ultrasound diagnostic instrument with a linear array probe (frequency 7-13 MHz). The lung was divided into 12 areas, and each area of both lungs was scanned successively.The lung ultrasound score in each area was recorded.The results with the highest scores were considered as the ultrasound results of this area.The general conditions of the pediatric patients were recorded and the fluid volume (input minus output) per kilogram per minute was calculated. Results:Compared with the values at T 0, the scores for lung consolidation and the pulmonary edema in lateral area were significantly increased at T 1, and the scores for lung consolidation, pulmonary edema and pleural effusion in posterior area and total score for lung consolidation, pulmonary edema and pleural effusion in each area were increased at T 1, 2 ( P<0.05). Compared with the values at T 1, the scores for lung consolidation in posterior area and total score for lung consolidation in each area were significantly decreased, and the scores for pulmonary edema in lateral and posterior areas and total score for pulmonary edema in each area were decreased at T 2 ( P<0.05), and no significant change was found in the lung ultrasound scores in anterior area at each time point ( P>0.05). Compared with the values in anterior area, the scores for lung consolidation at each time point were significantly increased, scores for pulmonary edema at T 1, 2 were increased, and score for pleural effusion at T 1 was increased in lateral area, and scores for lung consolidation, pulmonary edema and pleural effusion at each time point were increased in posterior area ( P<0.05). Compared with the values in lateral area, the scores for lung consolidation, pulmonary edema and pleural effusion at each time point were significantly increased in posterior area ( P<0.05). Conclusion:Lung consolidation, pulmonary edema and pleural effusion tend to occur in the lateral and posterior areas of the lung at 1 day after living-related liver transplantation, and the complications are severer in posterior areas.The lung consolidation in the posterior region is alleviated than that in the anterior area, and the pulmonary edema in the lateral and posterior areas is alleviated than that in the anterior area.However, all of these indexes don′t return back to their preoperative status.
