ObjectiveTo explore the clinical value of three early predictive scale of lung injury (ALI) in patients with high risk of acute lung injury (ALI) after lung cancer surgery.MethodsA convenient sampling method was used in this study. A retrospective analysis was performed on patients with lung cancer underwent lung surgery. The patients were divided into an ALI group and a non-ALI group according to ALI diagnostic criteria. Three kinds of lung injury predictive scoring methods were used, including lung injury prediction score (LIPS), surgical lung injury prediction (SLIP) and SLIP-2. The differences in the scores of the two groups were compared. The correlation between the three scoring methods was also analyzed. The diagnostic value was analyzed by drawing receiver operating characteristic (ROC) curves.ResultsA total of 400 patients underwent lung cancer surgery, and 38 patients (9.5%) developed ALI after operation. Among them, 2 cases progressed to acute respiratory distress syndrome and were treated in intensive care unit. There were no deaths. The predictive scores of the patients in the ALI group were higher than those in the non-ALI group, and the difference was statistically significant (all P<0.001). There was a good correlation between the three scoring methods (allP<0.001). The three scoring methods had better diagnostic value for early prediction of high risk ALI patients after lung cancer surgery and their area under ROC curve (AUC) were larger than 0.8. LIPS score performed better than others, with an AUC of 0.833, 95%CI (0.79, 0.87).ConclusionThree predictive scoring methods may be applied to early prediction of high risk ALI patients after lung cancer surgery, in which LIPS performs better than others.
Objective To investigate the status of frailty in patients with coronavirus disease 2019 (COVID-19), and to analyze the influence of COVID-19 disease on the prevalence of frailty. Methods This study was conducted using a cross-sectional survey method. COVID-19 patients admitted to a centralized isolation point in Guangzhou were selected for an questionnaire survey by “questionnaire star”, between November and December 2022. The questionnaire included the general information questionnaire, Tilburg Frailty Indicator (TFI), the COVID-19 symptom scale and Mental Resilience Scale (RS-11). Multi-model logistic regression analysis was used to explore the influence of COVID-19 on the occurrence of debilitation. Results A total of 667 questionnaires were distributed, of which 594 were valid, with an effective rate of 89.1%. There were 150 patients (25.3%) were frail, 444 patients (74.7%) were non-frail, and 51 patients (8.6%) were newly frail after infected COVID-19. The median TFI score before COVID-19 was 3 (2, 4) points, 16.7% (99/594) were in a weak state. The median TFI score after COVID-19 was 3 (2, 5) points, 25.3% (150/594) were in a weak state. There were statistically significant differences in TFI scores (Z=?6.596, P＜0.001) and the incidence of debilitation (χ2=351.648, P＜0.001) before and after COVID-19. The results of multivariate logistic regression analysis showed that after controlling disease factors, demographic factors and psychosocial factors, the score of the COVID-19 symptom score was always the influencing factor of COVID-19 patients. The overall change trend of COVID-19 symptom score was statistically significant (P<0.001). Conclusions The COVID-19 symptom score is an important risk factor or predictor of frailty in patients with COVID-19. As the level of COVID-19 symptom score increases, the risk of frailty in COVID-19 patients increases.

Methods A total of 1200 cases who need cesarean section were randomly divided into 3 groups (400 cases in each group): simple local anesthesia group (group L), droperidolfentanyl strengthen local anesthesia group (group F) and analgestic and amnestic anesthesia group (group J). Group L was only local anesthesia. Group F was local anesthesia supplemented by droperidol 500 mg, fentanyl 015 mg. Group J was supplemented with ketamine on the basis of group F. Then the time from anesthesia to the fetus delivery, Neonatal Apgar score of one and five minutes, the blood pressure fluctuations, amount of bleeding in or after surgery and the satisfaction of anesthesia were all observed. Results Compared with group L and F, the delivery time was no significant difference, Apgar score increased, blood pressure fluctuations in pregnant women was not obviously varied, amount of bleeding in or after surgery had no significantly increase, and the satisfaction of anesthesia improved markedly all in group J. Conclusions The analgestic and amnestic anesthesia assisted by lowdose ketamine, in cesarean section, is better than local anesthesia and strengthen local anesthesia by droperidolfentanyl, which is worthy to be popularized, especially in emergency caesarean section.
Objective To investigate the effectiveness of joystick technique assisted closed reduction and cannulated screw fixation in the treatment of femoral neck fracture. Methods Seventy-four patients with fresh femoral neck fractures who met the selection criteria between April 2017 and December 2018 were selected and divided into observation group (36 cases with closed reduction assisted by joystick technique) and control group (38 cases with closed manual reduction). There was no significant difference in gender, age, fracture side, cause of injury, Garden classification, Pauwels classification, time from injury to operation, and complications (except for hypertension) between the two groups (P>0.05). The operation time, intraoperative infusion volume, complications, and femoral neck shortening were recorded and compared between the two groups. Garden reduction index was used to evaluate the effect of fracture reduction, and score of fracture reduction (SFR) was designed and was used to evaluate the subtle reduction effect of joystick technique. ResultsThe operation was successfully completed in both groups. There was no significant difference in operation time and intraoperative infusion volume between the two groups (P>0.05). All patients were followed up 17-38 months, with an average of 27.7 months. Two patients in the observation group received joint replacement due to failure of internal fixation during the follow-up, and the other patients had fracture healing. Within 1 week after operation, the Garden reduxtion index of the observation group was better than the control group; the SFR score of the observation group was also higher than that of the control group; the proportion of femoral neck shortening within 1 week after operation and at 1 year after operation in the observation group were lower than those in the control group. The differences of the above indexes between the two groups were significant (P<0.05). ConclusionThe joystick technique can improve the effectiveness of closed reduction of femoral neck fractures and reduce the incidence of femoral neck shortening. The designed SFR score can directly and objectively evaluate the reduction effect of femoral neck fracture.

As a result, the ethic committee required researchers to report all data of safety of the drug and have all subjects rechecked about their liver function so as to provided reasonable evidence for the scientifical evaluation of the relationship between the drug and the adverse event and the succedent suspending of the clinical trial.
ObjectiveThe low anterior resection syndrome (LARS) score is a simple and visual instrument assessing sphincter preserving surgery for low rectal cancer. The purpose of this study is to analyze the feasibility of using LARS score to assess the function after intersphincteric resection for low rectal cancer.
MethodsBetween March 2013 and June 2015, 76 patients underwent sphincter preserving surgery for low rectal cancer, 23 cases underwent intersphincteric resection set as ISR group, the other 53 cases received low anterior resection set as LAR group. LARS score, Saito function questionnaire, Wexner score, and European organization for research and treatment of cancer (EORTC) quality of life questionnaire core 30 (QLQ-C30), questionnaire module for colorectal cancer (QLQ-CR29) were compared for the two groups.
ResultsThere were 63.2 percent patients (48/76) appeared major LARS, 27.6 percent (21/76) minor LARS and 9.2 percent (7/76) no LARS, there were no statistically difference between the ISR and LAR groups (P=0.727), but the item of incontinence due to liquid stools appeared more obvious in ISR group (P=0.009). The items of faecel incontinence and sore skin for EORTC QLQ-CR29 were serious in ISR group (P < 0.05), the other item of EORTC QLQ-CR29 and EORTC QLQ-C30, Saito function questionnaire, Wexner score were similar between the two groups (all P > 0.05).
ConclusionThe anal function after intersphincteric resection is non-inferior to the low anterior resection for low rectal cancer, but both can appear serious low anterior resection syndrome.
Objective
To Assess the efficacy of using lung ultrasound to guide alveolar recruitment maneuver in patients with acute respiratory distress syndrome (ARDS).
Methods
Sixty patients with ARDS were randomly divided into two groups, ie, maximal oxygenation group (n=30) and lung ultrasound group (n=30). All the patients had artificial airway and needed mechanical ventilation. The patients in the two groups accepted recruitment maneuver guided by maximal oxygenation or lung ultrasound respectively. During the course of recruitment maneuver, the arterial partial pressure of oxygen (PaO2), positive end-expiratory pressure (PEEP), central venous pressure (CVP), mean arterial pressure (MAP), cardiac output (CO), and extravascular lung water index (EVLWI) were recorded and compared between both groups.
Results
The PaO2 in lung ultrasound group was higher than that in maximal oxygenation group (P=0.04). The PEEP was higher in lung ultrasound group but without significant difference (P=0.910). There was no significant difference of the other outcomes (CVP, MAP, CO, EVLWI) between the two groups (all P>0.05).
Conclusion
Lung ultrasound is an effective means that has good repeatability and security for guiding recruitment maneuver in patients with ARDS.
Due to the minimum free energy model, it is very important to predict the RNA secondary structure accurately and efficiently from the suboptimal foldings. Using clustering techniques in analyzing the suboptimal structures could effectively improve the prediction accuracy. An improved k-medoids cluster method is proposed to make this a better accuracy with the RBP score and the incremental candidate set of medoids matrix in this paper. The algorithm optimizes initial medoids through an expanding medoids candidate sets gradually.The predicted results indicated this algorithm could get a higher value of CH and significantly shorten the time for calculating clustering RNA folding structures.
Objective To evaluate the diagnostic yield and safety of two biopsy methods, electromagnetic navigational bronchoscopy (ENB) and transthoracic needle biopsy (TTNB), in peripheral pulmonary lesions. To select a low-risk and high-benefit biopsy method based on the clinical characteristics of the lesions and patients. Methods A retrospective analysis was conducted on inpatients who underwent ENB and/or TTNB for peripheral pulmonary lesions in Huadong Hospital Affiliated to Fudan University. Propensity score matching was used to compare the diagnostic yield and safety of the two biopsy methods. Results A total of 126 patients were included in the ENB group, and 104 patients in the TTNB group. After propensity score matching, 83 matched pairs were obtained. The TTNB group exhibited a significantly higher diagnostic yield compared with the ENB group (90.4% vs. 48.2%, P<0.001), but it was also associated with a higher incidence of pneumothorax (1.2% vs. 21.7%, P<0.001). In the ENB group, the diagnostic efficacy was correlated with lesion diameter (P<0.001, OR=0.183, 95%CI 0.071 - 0.470), but there was no statistically significant difference in the diagnostic yield among different lung segments (P>0.05). In the TTNB group, lesion characteristics did not significantly affect the diagnostic yield, but a lesion diameter ≤30 mm (P=0.019, OR=5.359, 95%CI 1.320 - 21.753) and a distance from the pleura ≥20mm (P=0.030, OR=6.399, 95%CI 1.192 - 34.360) increased the risk of pneumothorax. When stratified based on lesion and patient blood characteristics, no significant difference was found in the diagnostic yield between the two groups for characteristics such as left upper lobe (P=0.195), right middle lobe (P=0.333), solid with cavity (P=0.567), or abnormal serum white blood cell count (P=0.077). However, the incidence of pneumothorax in the TTNB group was higher than that in the ENB group. Conclusions The diagnostic yield of ENB is affected by the size of the lesion, while the incidence of pneumothorax in TTNB is influenced by both lesion size and distance from the pleura. In cases with lesions located in the left upper lobe, right middle lobe, solid with cavity, or with abnormal serum white blood cell count, selecting ENB for biopsy is considered preferable to TTNB.
ObjectiveTo summarize the clinical value of Caprini risk score (CRS) and D-dimer testing, both individually and in combination, for venous thromboembolism (VTE) risk stratification in patients undergoing laparoscopic surgery. MethodsThrough systematic literature review and analysis, we evaluated the advantages and limitations of these two tools in predicting VTE, with emphasis on their combined utility and respective detection characteristics. ResultsCRS demonstrated superior population stratification efficacy for initial VTE screening post-laparoscopy but showed limitations in assessing individual heterogeneity. D-dimer testing exhibited high sensitivity in detecting postoperative hypercoagulable states, yet its specificity was confounded by surgical stress-induced coagulation activation. Their integration established a multidimensional assessment system that significantly enhanced identification accuracy of high-risk VTE populations. ConclusionsThe combined application of CRS and D-dimer biomarkers optimizes postoperative VTE risk stratification management and provides evidence-based guidance for defining precise anticoagulation therapy timeframes. Future research should prioritize refinement of risk assessment tools to facilitate dynamic patient monitoring, thereby guiding targeted thromboprophylaxis and reducing occult VTE risk.
