This article takes pectoral qi as the starting point to discuss the traditional Chinese medicine(TCM)pathogenesis as well as the diagnostic and therapeutic approach to difficult withdrawal of mechanical ventilation in mechanically ventilated patients.According to the five-viscera correlation theory,it is believed that the onset of difficult withdrawal of mechanical ventilation is closely related to pectoral qi.The core pathogenesis of difficult withdrawal of mechanical ventilation is due to the insufficiency of pectoral qi and the deficiency of the lung,spleen and kidney,and the obstruction of pectoral qi and disharmony of qi and blood contribute to the key pathogenesis.Chinese medicine treatment can be carried out by the usage of Sijunzi Tang(Four Mild-Drug Decoction),Bufei Tang(Decoction for Replenishing Lung),Shenling Baizhu San(Powder of Radix Ginseng,Poria and Rhizoma Atractylodis Macrocephalae)to supplement and benefit pectoral qi,and by the utilization of Buzhong Yiqi Tang(Decoction for Tonifying Middle Energizer and Replenishing Qi),Shengxian Tang(Decoction for Lifting the Sinking of Qi in Chest),Juyuan Jian(Decoction for Replenishing Qi and Lifting the Sunken Qi)to elevate yang and lift the sinking of Qi.Moreover,herbs for regulating qi and blood should be added,and the management of the diet and daily living based on the identification of the deficiency and excess of the five viscera is stressed,so as to enhance the success rate of withdrawal of mechanical ventilation.The exploration will provide ideas for the treatment of difficult withdrawal of mechanical ventilation with the integrated Chinese and western medicine.

Purpose To investigate the corr-elation between Rap1 GAP expression in colon cancer tissues and clinicopatho-logical features and prognosis.Methods Immunohistochemistry was used to detect Rap1 GAP protein expression in 125 cases of colon cancer,and its correlation with clinicopathological features and prognosis was analyzed.Rap1 GAP protein expression in co-lon cancer LOVO,HCT116,SW480 cells and normal colon epi-thelial HCoEPiC cells was detected by Western blot.The expres-sion of Rap1 GAP was down-regulated and up-regulated in LO-VO,HCT116 and SW480 cells by lentivirus transfection,and di-vided into no-load group(sh-NON,LV-NON),sh-Rap1 GAP group(low expression Rap1 GAP)and LV-Rap1 GAP group(overexpression Rap1 GAP)according to different treatments.The transfection efficiency was verified by Western blotting.MTT assay and Transwell assay were used to detect cell proliferation,invasion and migration in each group.Results In 125 colon cancer samples,83 cases(66.4％)had the loss of Rap1 GAP expression,which was higher than that in paracancer control(7.2％,P＜0.001).The rate of loss of Rap1 GAP expression was correlated with the degree of tumor differentiation(x2=6.152,P=0.011)and the presence of mucinous adenocarcino-ma(x2=4.908,P=0.028),but not with gender,age,tumor location,tumor stage,or lymph node metastasis(P＞0.05).Western blotting results showed that compared with HCoEPiC(0.189±0.081)cells,Rap1 GAP protein expression was in-creased in colon cancer LOVO(0.238±0.008)cells.Rap1 GAP protein expression was decreased in HCT116(0.064± 0.002)and SW480(0.152±0.026)cells(F=159.6,P＜0.05).After LOVO cells were transfected with Rap1 GAP low expression lentivirus,the expression level of Rap1 GAP in sh-Rap1 GAP-1 group(0.733±0.071)and sh-Rap1 GAP-2 group(0.559±0.136)and sh-Rap1 GAP-3 group(0.606±0.037)was significantly lower than that in LOVO group(1.880± 0.129)(F=49.57,P＜0.05).Compared with sh-NON(1.260±0.109)group,the proliferation ability of sh-Rap1 GAP-2(1.569±0.059)and sh-Rap1 GAP-3(1.548±0.087)cells was significantly increased at 72 h(F=28.36,P＜0.05).Its invasion and migration ability were significantly increased(P＜0.05).After HCT116 cells transfected with overexpression lentivirus,the expression of Rap1 GAP protein in LV-Rap1 GAP group(1.395±0.137)was relatively higher than that in LV-NON group(0.485±0.097)(P＜0.05).The results of MTT assay showed that compared with LV-NON(0.652±0.047)group,the proliferation ability of cells in LV-Rap1 GAP(1.212 ±0.038)group was decreased,and the invasion and migration ability were significantly decreased(P＜0.05).The transfection results,proliferation,invasion and migration of SW480 cells were consistent with those of HCT116 cells.Conclusion The loss rate of Rap1 GAP expression is related to the differentiation degree of colon cancer and whether it is accompanied by mucin-ous adenocarcinoma.The up-regulation of Rap1 GAP expression can inhibit the proliferation,invasion and migration of colon cancer cells,providing a theoretical basis for exploring the occur-rence and development of colon cancer.

Objective:To explore the relationship between the Prognostic Nutritional Index (PNI) and the HALP score with the prognosis of patients with middle-to-advanced prostate cancer. Methods:A total of 168 patients with middle-to-advanced prostate cancer admitted to three comprehensive tertiary hospitals were observed from 2013 to 2018. Patient medical records were reviewed,and overall survival (OS) and progression-free survival (PFS) were followed up. The receiver operating characteristic (ROC) curve was used to calculate the area under the curve (AUC) and the optimal cut-off value of PNI and HALP scores for predicting patients' prognosis. The Kaplan-Meier method was used to draw survival curves,and the Log-rank test and Cox regression were used to analyze the influencing factors of patient OS and PFS. Results:The follow-up period was 55 (38.5,63) months,with 87 deaths (51.79％) during this period. The median OS and PFS times were 50 months and 45 months,respectively. The 3-year OS and PFS survival rates were 72.02％ and 64.29％,respectively. The areas under the ROC curve for predicting patients' prognosis with PNI and HALP scores were 0.912 and 0.828,respectively,with optimal cut-off values of 46.3 and 31.64 (P<0.05). Multivariate Cox regression showed that PNI<46.3,HALP score<31.64,and age ≥ 60 years were risk factors for OS with HR (95％ CI) of 6.016 (3.273～11.056),2.537 (1.531～4.205),and 1.776 (1.221～2.967),respectively (P<0.05). AJCC stage Ⅳ,PNI<46.3,and HALP<31.64 were risk factors for PFS with HR (95％ CI) of 2.777 (1.381～5.419),5.940 (3.245～10.872),and 2.481 (1.498～4.109),respectively (P<0.05). Conclusion:PNI and HALP scores can predict the prognosis of patients with middle-to-advanced prostate cancer.

Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

Objective:To investigate a new method for the reconstruction of hemifacial microsomia by sagittal osteotomy of the affected mandibular outer cortex combined with bone graft of mandibular outer cortex from healthy side.Methods:From March 2006 to March 2023, the clinical data of patients with hemifacial microsomia admitted to the Department of Craniomaxillofacial Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences were analyzed retrospectively. Preoperative diagnosis and surgical design were performed based on clinical manifestations and imaging findings. All cases were operated under general anesthesia. The affected mandibular outer cortex was previously split by an intraoral approach, and then the mandibular outer cortex of appropriate shape and size on the healthy side was harvested and grafted into the split bone space according to the preoperative design, following by internal rigid fixation. Complications, facial appearance improvement, and patient satisfaction were followed up. Photographs were taken preoperative, immediately postoperative and at the long-term(last) postoperative follow-up, and the severity of the deformity was analyzed. CT data from preoperative, immediate postoperative, and long-term follow-up visits were imported into Surgicase Proplan medical three-dimensional image workstation in Dicom format. The mandible was reconstructed using Segmentation, and the thickness of the mandible was measured during pre-operative, immediate post-operative and long-term follow-up visits. Anova with repeated measurement design was used to compare measurements and LSD test was used for multiple comparisons. The Kruskal-Wallis rank sum test were used to statistically analyze malformation severity. P< 0.05 is considered statistically significant. Results:A total of 39 patients were included in this study, including 13 females and 26 males, with an average age of (22.21±4.57) years (15-27 years). All patients were followed up for an average of (45.56±39.41) months (6-153 months) after surgery. The grafted mandibular outer cortex grows well with the adjacent bone tissue, and the mandibular angle and mandibular body are significantly wider. Of the 39 cases, 1 developed an infection 1 year after surgery, the titanium plate was exposed, and the patient healed after debridement and removal of the immobilizing splint. The facial appearance of the other patients improved significantly. Preoperative, immediate postoperative and long term follow up of mandibular thickness measurements were compared in pairs, and the differences were statistically significant (all P<0.05). The patient’s appearance satisfaction score: the preoperative score was [2.0(1.5, 2.0)] points, the immediate postoperative score was [4.0(4.0, 4.0)] points, the score of the last postoperative follow up was [4.0(4.0, 4.0)] points. There was statistical difference in satisfaction among the three groups ( P<0.01). The preoperative scores were compared with the scores of the immediate postoperative and the last postoperative follow-up respectively, and the differences were statistically significant( P<0.01). There was no statistical significance in satisfaction between the immediate postoperative score and the score of the last postoperative follow up ( P>0.05). Conclusion:The sagittal splitting osteotomy of the mandibular outer cortex is consistent with the features of mandibular anatomy, and provides a good condition for the grafting and healing of autogenous bone. Removing the outer cortex of the mandible on the healthy side not only increases the thickness of the affected side, but also decreases the width of the angle of the mandible on the healthy side, so as to effectively correct the asymmetric deformity of the mandible. The method is simple, with few complications and good results, and is one of the ideal treatments to correct hemofacial microsomia.

Purpose::To assess the value of the driving pressure variation rate (ΔP%) in predicting the outcome of weaning from invasive mechanical ventilation in patients with acute respiratory distress syndrome.Methods::In this case-control study, a total of 35 patients with moderate-severe acute respiratory distress syndrome were admitted to the intensive care unit between January 2022 and December 2022 and received invasive mechanical ventilation for at least 48 h were enrolled. Patients were divided into successful weaning group and failed weaning group depending on whether they could be removed from ventilator support within 14 days. Outcome measures including driving pressure, PaO 2:FiO 2, and positive end-expiratory pressure, etc. were assessed every 24 h from day 0 to day 14 until successful weaning was achieved. The measurement data of non-normal distribution were presented as median (Q 1, Q 3), and the differences between groups were compared by Wilcoxon rank sum test. And categorical data use the Chi-square test or Fisher's exact test to compare. The predictive value of ΔP% in predicting the outcome of weaning from the ventilator was analyzed using receiver operating characteristic curves. Results::Of the total 35 patients included in the study, 17 were successful vs. 18 failed in weaning from a ventilator after 14 days of mechanical ventilation. The cut-off values of the median ΔP% measured by Operator 1 vs. Operator 2 in the first 4 days were ≥ 4.17% and 4.55%, respectively ( p < 0.001), with the area under curve of 0.804 (sensitivity of 88.2%, specificity of 64.7%) and 0.770 (sensitivity of 88.2%, specificity of 64.7%), respectively. There was a significant difference in mechanical ventilation duration between the successful weaning group and the failure weaning group (8 (6, 13) vs. 12 (7.5, 17.3), p = 0.043). The incidence of ventilator-associated pneumonia in the successful weaning group was significantly lower than in the failed weaning group (0.2‰ vs. 2.3‰, p = 0.001). There was a significant difference noted between these 2 groups in the 28-day mortality (11.8% vs. 66.7%, p = 0.003). Conclusion::The median ΔP% in the first 4 days of mechanical ventilation showed good predictive performance in predicting the outcome of weaning from mechanical ventilation within 14 days. Further study is needed to confirm this finding.
