Objective:To compare the efficacy of individualized PEEP determined by lung electrical impedance tomography (EIT) and dynamic lung compliance (Cdyn) during lung-protective ventilation strategies in the patients undergoing general anesthesia.Methods:Sixty patients of both sexes, aged 18-64 yr, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, with body mass index of 18.5-28.0 kg/m 2, undergoing elective surgery with general anesthesia and endotracheal intubation in the Second Affiliated Hospital of Soochow University, were selected.Lung-protective ventilation strategy was applied in supine position after general anesthesia.The peak value of PEEP did not exceed 10 cmH 2O, with an increment/decrement of 2 cmH 2O for titration.The corresponding Cdyn value and lung EIT data were collected during titration.The patients were divided into 2 groups ( n=30 each) using a random number table method: titration first increased and then decreased group (group A) and titration first decreased and then increased group (group B). The determination method of individualized PEEP: Cdyn method was the PEEP corresponding to the maximum Cdyn value; EIT method was obtained through PV500 PC software analysis.The level and success rate of individualized PEEP determined by the Cdyn and EIT methods were compared, and the ICC consistency analysis of the determined individualized PEEP was performed. Results:Compared with the Cdyn method, the success rate of individualized PEEP determined by EIT method was significantly increased, and the level of individualized PEEP was decreased in the two group ( P<0.05). In group A, the individualized PEEP titrated by the EIT and Cdyn methods showed good agreement (the ICC value of the increment-Cdyn and increment-EIT methods was 0.761, P<0.05; the ICC value of the decrement-Cdyn and decrement-EIT methods was 0.763, P<0.05). In group B, the individualized PEEP titrated by the EIT and Cdyn methods showed good agreement (the ICC value of the increment-Cdyn and increment-EIT methods was 0.809, P<0.05; the ICC value of the decrement-Cdyn and decrement-EIT methods was 0.797, P<0.05). Conclusion:The agreement between the individualized PEEP determined by lung EIT method and Cdyn method during lung-protective ventilation is good in the patients undergoing general anesthesia, and the success rate of EIT method is higher, and the level of individualized PEEP is lower.

Objective To analyze the clinical efficacy of the laparoscopic breast-conserving surgery combined with radiofrequency ablation to treat the early-stage breast cancer.Methods We collected 55 patients diagnosed early-stage breast cancer in retrospect,which started from January 2014 to December 2016.Twenty-seven of them were performed the laparoscopic breast-conserving surgery combined with radiofrequency ablation while others went through laparoscopic breast-conserving surgery without radiofrequency ablation.Meanwhile,we adopted the student t-test and the chi-square test to compare results of two groups.More specific,the main indexes of this study are including the post-operative local recurrence,the incidence of fat liquefaction or the incision-infection,operation time,post-operative hospital stay and the hospitalization expense.Results The laparoscopic breast-conserving surgery combined with radiofrequency ablation group had low local-recurrence than the laparoscopic breastconserving surgery group (0 and 7.69％).Additionally,there were no statistical differences between two groups in the incidence of fat liquefaction.However,The laparoscopic breast-conserving surgery combined with radiofrequency ablation group had more hospitalization expense than the laparoscopic breast-conserving surgery group [(4.1 ± 0.7) ten thousand yuan and (2.3 ± 0.6) ten thousand yuan,P ＜ 0.05].Conclusions Although the laparoscopic breast-conserving surgery combined with radiofrequency ablation group remarkably increased the hospitalization expense because of the utility of the radiofrequency ablation related apparatus,it may provide the probability of shaving more residual tumor cell and may low down the recurrence,especially not rising up the incidence of the post-operative fat liquefaction.Therefore,this surgery method might be one of the potential developments in the minimal-invasive of early stage breast cancer.

Objective:To evaluate the effect of propofol and remifentanil in different target-controlled infusion(TCI) sequences on hypotension during induction of general anesthesia in hypertensive patients.Methods:A total of 132 patients with hypertension of both sexes, aged 50-75 yr, of American Society of Anesthesiologists Physical Status classificationⅡ or Ⅲ, with body mass index of 18-30 kg/m 2, scheduled for elective tracheal intubation under general anesthesia, were divided into 3 groups( n=44 each) using a random number table method: group C, PR group and RP group. In group C, propofol(target effect-site concentration 5 μg/ml) and remifentanil(target effect-site concentration 5 ng/ml) were simultaneously given by TCI. Propofol was given by TCI followed by TCI of remifentanil in PR group. Remifentanil was given by TCI followed by TCI of propofol in RP group. The development of hypotension was observed within 10 min after induction of general anesthesia, and the consumption of propofol, remifentanil and ephedrine, time of loss of consciousness, time of tracheal intubation and adverse reactions during the perioperative period were recorded. Results:Compared with group C, the incidence of hypotension during induction was significantly decreased, the consumption of propofol and ephedrine was decreased, and the BIS value was increased when consciousness disappeared, the time of loss of consciousness and time of tracheal intubation were prolonged, the BIS value was increased at loss of consciousness in PR group, and the consumption of ephedrine was significantly decreased, and the time of loss of consciousness and time of tracheal intubation were prolonged in RP group( P<0.05). Compared with PR group, the consumption of ephedrine was significantly decreased, and the time of loss of consciousness was prolonged in RP group( P<0.05). There was no significant difference in the incidence of responses to tracheal intubation, injection pain, bucking, inhibition ratio, postoperative delirium, postoperative nausea and vomiting, and intraoperative awareness during induction among the three groups( P>0.05). Conclusions:TCI of remifentanil followed by TCI of propofol can decrease the development of hypotension during induction of general anesthesia in hypertensive patients.

Objective:To evaluate the clinical efficacy of Gushen Jianpi Huashi Decoction combined with irbesartan in the treatment of spleen and kidney deficiency syndrome of diabetic nephropathy (DN).Methods:According to random number table method, 97 patients with DN who met the inclusion criteria and from January 2018 to September 2020 were randomly divided into two groups, 48 in the control group and 49 in the study group. The control group took irbesartan on the basis of routine treatment of western medicine, and the study group took Gushen Jianpi Huashi Decoction on the basis of the control group. Both groups were treated for 14 days as a course of treatment, a total of 6 courses of treatment. Traditional Chinese Medicine (TCM) syndrome scores were performed before and after treatment, BUN and SCr levels were detected by automatic biochemical instrument, and serum IL-6, TNF-α, and CRP levels were detected by ELISA. The Urinary microalbumin excretion rate (UAER) was measured by radioimmunoassay, and the clinical efficacy was evaluated and adverse reactions were recorded.Results:The total effective rate was 91.8% (45/49) in the study group and 75.0% (36/48) in the control group, and there was significant difference between the two groups ( χ2=4.99, P=0.025). The scores of TCM syndrome in the study group was significantly lower than that of the control group ( t=29.75, P<0.01). After treatment, the serum BUN [(4.49 ± 0.68) mmol/L vs. (5.16 ± 0.61) mmol/L, t=5.11], SCr [(63.42 ± 4.09) μmol/L vs. (69.01 ± 4.35) μmol/L, t=6.52] and UAER [(72.58 ± 5.88) μg/min vs. (85.63 ± 6.49) μg/min, t=10.44] in the study group were significantly lower than those in the control group ( P<0.01), the serum IL-6, CRP and TNF-α levels in the study group were significantly lower than those in the control group ( t values were 9.44, 7.24 and 18.08, respectively, P<0.01). During the treatment, the incidence of adverse reactions was 14.6% (7/48) in the control group and 16.3% (8/49) in the study group, but there was no significant difference between two groups ( χ2=0.06, P=0.812). Conclusion:The Gushen Jianpi Huashi Decoction combined with irbesartan can improve the renal function of DN patients, reduce the level of inflammatory cytokines and improve the clinical effect.

Objective To determine the optimal positive end-expiratory pressure (PEEP) for volume-controlled ventilation using pulmonary electrical impedance tomography in the patients undergoing surgery with general anesthesia.Methods Fifty patients of both sexes,aged 18-64 yr,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,with body mass index of 18.5-28.0 kg/m2,scheduled for surgery for ureteral calculi under general anesthesia,were enrolled in this study.The patients were tracheally intubated after anesthesia induction and mechanically ventilated in volume-controlled mode,with tidal volume 6 ml/kg,mean arterial pressure was recorded at 3 min of ventilation and served as the baseline value,and then PEEP was increased with an increment of 3 cmH2O every 3 min until PEEP reached 15 cmH2 O.The percentage of dorsal pulmonary ventilation and peak airway pressure were recorded at 3 min of ventilation with different PEEPs.When the decrease in mean arterial pressure was more than 20％ of the baseline value during ventilation,deoxyepinephrine 0.1 mg was injected intravenously,and the consumption of deoxyepinephrine was recorded within 3 min of ventilation with different PEEPs.Results Peak airway pressure was gradually increased with the increase of PEEP (P＜0.05),the percentage of dorsal pulmonary ventilation was gradually increased when PEEP was 6 cmH2O (P＜ 0.05),and the consumption of deoxyepinephrine was gradually increased when PEEP was 15 cmH2O (P＜0.05).Conclusion The optimal PEEP is 12 cmH2O during volume-controlled ventilation with tidal volume of 6 ml/kg in the patients undergoing surgery with general anesthesia.

In China,the surgical technique of liver transplantation has become mature,however,the graft injuries,the personalized-adjustment of the immunosuppression and the rejection after the operation have been increasing prominently.Especially,the un-reversible chronic rejection and the side-effect of the over-dosage or under-dosage immunosuppression should be emphasized.Adopting the liver function examination and the liver-biopsy to monitor the graft function have disadvantages such as traumatic,time-consuming and low sensitivity.Recently,adopting the graft-derived cell-free DNA to monitor the graft health has becoming the research hotspots.The followings summarize the application of the graft-derived cell-free DNA after the operation.

Objective:To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for early hypopharyngeal carcinoma and precancerous lesions.Methods:Clinical data of 41 patients who received ESD for early hypopharyngeal carcinoma and precancerous lesions from August 2013 to August 2019 in the Department of Endoscopy of Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College were retrospectively analyzed. Main outcome measurements included operation completion rate, operation time, en bloc resection rate, R0 resection rate, complication rate and recurrence.Results:ESD was successfully completed in all 41 cases, with a success rate of 100.0% and a mean time of 49.1 min (ranged 10-110 min). Fifty-four lesions underwent en bloc resection, with an en bloc resection rate of 98.2% (54/55), of which 41 had negative horizontal and vertical margins, and the R0 resection rate was 74.5% (41/55). During the operation of 55 lesions, there was a small amount of blood oozing on the wound surface, and electrocoagulation with thermal biopsy forceps could successfully stop the bleeding. No perforation occurred, and 2 cases (4.3%) had delayed bleeding after ESD, and hemostasis was successful under emergency endoscopy. Postoperative endoscopy showed that 1 case (2.2%) had esophageal entrance stenosis, and the obstruction was relieved after repeated water balloon dilatation. The follow-up period ranged from 3 to 72 months, and the median time was 18 months. One case was found to have mucosal lesions in the same part of the hypopharynx and received ESD treatment again. Follow-up to October 2020, no residual lesions and recurrence were found.Conclusion:ESD is a safe and effective option for the treatment of early hypopharyngeal carcinoma and precancerous lesions, which is worthy of clinical application.

Objective According investigate the expression of NLRP3 in liver tissues of mice with hepatic ischemia-reperfusion injury (HIRI),to determin the role of NLRP3 in the process of HIRI.Methods Established mice model of partial HIRI.Forty-two male C57BL/6 mice (aged 7 to 8 weeks,weight 20 to 25 g) were respectively divided into 7 groups:no-treatment control group,sham operation group,HIRI groups (2、6、12、24 h) and CY-09 group,6 mice in each group.The injury of the hepatic tissues in the 7 groups was analyzed based on detecting the levels of alanine transaminase (ALT),aspartate transaminase (AST),interleukin-1β (IL-1β),interleukin-18 (IL-18),tumor necrosis factor-α (TNF-α) by ELISA.HE and TUNEL staining were used to observe the pathological changes of liver tissues after HIRI.Western blotting assay were carried out to detect the expressions of NLRP3 and Caspase-1.Measurement data were expressed as mean ± standard deviation (Mean ± SD),and one-way variance analysis was used for comparison between groups.If the variance was not uniform,Dunnett C test was used.Results Serum ALT,AST,IL-1 β,IL-18 and TNF-α of mice detected in HIRI groups were higher than no-treatment control group and sham operation group at all endpoints (P ＜ 0.05).The relative expression of NLRP3 and Caspase-1 in the liver tissues of mice in the HIRI groups were significantly higher than that in the no-treatment control group and sham operation group.Serum ALT,AST,IL-1β,IL-18 and TNF-α of mice detected in CY-09 group were lower than HIRI groups at all endpoints (P ＜ 0.05).Less hepatocellular necrosis were exhibited in CY-09 group,comparing to HIRI groups.The hepatocyte apoptosis rate of mice in the CY-09 group was significantly lower than that in the 12 h HIRI group (P ＜ 0.05).The relative expression of NLRP3 in the liver tissues of mice in the CY-09 group was significantly lower than that in other groups.The relative expression of Caspase-1 in the liver tissues of mice in the CY-09 group was significantly lower than that in other groups except the no-treatment control group and sham operation group.Conclusions HIRI cause an increase in NLRP3 expression.The inhibition of NLRP3 can reduce HIRI.
