OBJECTIVE To approach the nursing methods for protecting of the unilateral lung in eldly patients with severe pulmonary infection of both-sides after operation.METHODS The patients which had a relatively better function in one side ie.with a higher Sat-O2 value were selected.Using postural drainage and sputum aspiration in protecting the unilateral lung,turning the body over quickly and knocking the back of the body on the other-side of the lung were adopted to gradually recovered the pulmonary function side-by-side.RESULTS Through the new nursing model the pulmonary function and the Sat-O2 value could be improved.CONCLUSIONS When the both-sides of the pulmonary infected severely,nursing the unilateral lung at the beginning by using postural drainage,turning the body over quickly and knocking the back in the other side of the lungs,can efficiently speed up the proceeding of rehabilitation of pulmonary infection.

Objective Through clinical observation and statistics, to get the best curative effect of surgical operation in treating pigment nevus method and provide clinical guidance. Methods We reviewed of face and neck patients (1100 patients) with pigmented nevus in the department in the department of the dermatology,plastic surgery from January 2013 to October 2015, two different methods was designed on each parts and effect of the treatment, especially satisfaction degree was analyzed by statistical methods.Results In 100 cases of patients, only 20 patients had mild scar hyperplasia at the neck incision and the rest of the patients were satisfactory. For special parts such as mouth,nose and eye around,along thedirection of the muscle, arc and along the direction of dermatoglyph incision was designed respectively, patients obtained with higher postoperative satisfaction (P<0.05) . Conclusion In pigmented nevus of face and neck surgery treatment, surgical incision design requires dynamic and static combining method,incision design is important for the postoperative effect and patients' satisfaction.

Objective To compare the clinical effects of intravascular ultrasound (IVUS) and blood flow reserve fraction (FFR) in guiding the treatment of critical disease of coronary artery.Methods Forty nine patients with coronary artery disease who underwent coronary angiography were divided into IVUS group (n=43) and FFR group (n=51).In IVUS group,such as MLA ＜4 mm2 or coronary artery stenosis was insufficient,but IVUS showed unstable plaque,and we went the PCI treatment;in the FFR group,FFR＜0.75 was regarded as coronary stenting sign.The patients were followed up for 6 months.The incidence of cardiovascular adverse events was compared between the two groups.Results (1)There was no significant difference in general information and coronary angiography between the two groups (P＞ 0.05).(2)The proportion of interventional therapy in IVUS group was higher than that in FFR group (P＜0.01).(3)The incidence of adverse events between the two groups was not statistically significant (P＞0.05).Conclusion IVUS and FFR examination can be used to guide the interventional treatment of critical disease of coronary artery.However,the accuracy of IVUS can not replace the status of blood flow reserve.

Phase separation is an important mechanism that mediates the compartmentalization of proteins in cells. Proteins that can undergo phase separation in cells share certain typical sequence features, like intrinsically disordered regions (IDRs) and multiple modular domains. Sequence-based analysis tools are commonly used in the screening of these proteins. However, current phase separation predictors are mostly designed for IDR-containing proteins, thus inevitably overlook the phase-separating proteins with relatively low IDR content. Features other than amino acid sequence could provide crucial information for identifying possible phase-separating proteins:pro-tein–protein interaction (PPI) networks show multivalent interactions that underlie phase separation process; post-translational modifications (PTMs) are crucial in the regulation of phase separation behavior;spherical structures revealed in immunofluorescence (IF) images indicate condensed dro-plets formed by phase-separating proteins, distinguishing these proteins from non-phase-separating proteins. Here, we summarize the sequence-based tools for predicting phase-separating proteins and highlight the importance of incorporating PPIs, PTMs, and IF images into phase separation prediction in future studies.

Objective The aim of this study was to investigate the risk factors for delayed postoperative ileus(PPOI)in colon cancer patients undergoing complete laparoscopic right hemicolectomy combined with intraperitoneal thermal perfusion chemotherapy(HIPEC),and establish a risk prediction model.Methods A retrospective analysis was performed on the case data of 68 colon canc-er patients who underwent complete laparoscopic right hemicolectomy combined with HIPEC at the Department of General Surgery,the First Medical Center of PLA General Hospital from January 2018 to January 2021.The incidence of PPOI was statistically analyzed,and its risk factors were analyzed.A nomogram of risk prediction model was constructed and the effectiveness was verified.Results Among the 83 patients,26 cases(31.3％)developed PPOI.Multivariate logistic regression analysis showed that diabetes(OR=14.820,95％CI:2.819-77.918),previous abdominal surgery(OR=6.514,95％CI:1.433-29.604),preoperative Hb＜9 g/L(OR=5.338,95％CI:1.197-23.809),intraoperative hemorrhage more than 200 mL(OR=4.869,95％CI:1.213-19.544),and not close the mesangial hiatal(OR=5.462,95％CI:1.408-21.186)were the risk factors for PPOI.Based on the results of multiva-riate analysis,a risk prediction model for ROC curve and PPOI nomogram was constructed.The internal validation consistency index(C-index)was 0.85(95％CI:0.735-0.957).Conclusion The risk factors for PPOI after complete laparoscopic right hemicolec-tomy combined with HIPEC are diabetes,previous abdominal surgery,preoperative Hb＜9 g/L,intraoperative hemorrhage more than 200 mL,and failure to close the mesangial hiatal.The constructed nomogram of risk prediction model for PPOI after complete laparo-scopic right hemicolectomy has a good evaluating effect and clinical application value.

Background and objective Leptomeningeal carcinomatosis is a rare type of metastatic tumors of the central nervous system. In recent years, with the improvement of neoplasms therapies and longer survival of patients by better systemic control, incidence of leptomeningeal metastases has increased every year. However, there is still lack of effective thera-pies. hTe aim of this study is to investigate the effcacy, security and prognosis of intrathecal chemotherapy with methotrexate (MTX) in the treatment of neoplastic meningitis.Methods A total of 27 patients were enrolled. We investigated clinical fea-tures and cerebrospinal lfuid (CSF) examination results retrospectively, and analyzed the adverse reactions as well as prognosis atfer intrathecal chemotherapy.Results All 27 patients were treated by intrathecal MTX, 70.4% had clinical remission, how-ever, there was no signiifcant difference in CSF pressure and CSF biochemical changes. We observed that 55.6% patients were all appropriate, 25.9% appeared lower limb numbness and mild pain, no serious irreversible adverse reactions occurred. Median overall survival was 4 months.Conclusion We suggest that intrathecal administration of MTX is associated with improvement of symptoms of leptomeningeal metastasis patients and no severe adverse events observed.

Background and objectiveAdenosquamous carcinoma (ASC) is a rare subtype of lung cancer, it is mixed glandular and squamous cell carcinoma with a more aggressive behavior and poor prognosis than the other histologic subtypes. hTe aim of the study was to explore the clinicopathological characteristics and prognostic factors of ASC.Methods A total of 72 patients were enrolled. We investigated clinicalpathological features and prognostic factors retrospectively.Results hTe overall 72 ASC patients’ median age was 34.7 months, 5-year survival rate was 14.9%. hTe inlfuence of tumor size, M stage, and N stage, gene mutation and surgery on the prognosis of patients show statistical signiifcance.Conclusion ASC is charac-terized by both histologic aggressiveness and adverse prognosis. We suggest the comprehensive therapy based on surgery, and given small molecule tyrosine kinase inhibitors (TKIs) treatment may prolong patients’ overall survival.

Uncovering the risk factors of pulmonary hypertension and its mechanisms is crucial for the prevention and treatment of the disease.In the current study,we showed that experimental periodontitis,which was established by ligation of molars followed by orally smearing subgingival plaques from patients with periodontitis,exacerbated hypoxia-induced pulmonary hypertension in mice.Mechanistically,periodontitis dysregulated the pulmonary microbiota by promoting ectopic colonization and enrichment of oral bacteria in the lungs,contributing to pulmonary infiltration of interferon gamma positive(IFNγ+)T cells and aggravating the progression of pulmonary hypertension.In addition,we identified Prevotella zoogleoformans as the critical periodontitis-associated bacterium driving the exacerbation of pulmonary hypertension by periodontitis,and the exacerbation was potently ameliorated by both cervical lymph node excision and IFNγ neutralizing antibodies.Our study suggests a proof of concept that the combined prevention and treatment of periodontitis and pulmonary hypertension are necessary.

ObjectiveTo explore the effect of the serum containing Huanglian Wendantang on pyroptosis in vitro model of insulin resistance and its mechanism. MethodSD rats were randomly divided into two groups， namely Huanglian Wendantang-containing serum group and blank serum group， and given 7.8 g·kg^-1·d^-1 Huanglian Wendantang and equal volume of normal saline by intragastric administration according to body surface area. Blank serum and medicated serum with different concentration were extracted and prepared. HepG2 cells were treated with sodium palmitate to construct the model of insulin resistance （IR）， and they were randomly divided into control group， model group， metformin hydrochloride group， blank serum group， and Huanglian Wendantang-containing serum high-， medium-， and low-dose groups. After 24 h of cultivation， the cells of each group were treated with insulin for 15 min at concentration of 1×10^-7 mol·L^-1， and the cell supernatant was collected. The glucose oxidase （GOD-POD） kit was used to determine the glucose content of each group， and calculate the glucose consumption and inhibition rate. The methyl thiazolyl tetrazolium （MTT） assay was used to detect the cell proliferation， thus screening out the optimal dose of serum containing Huanglian Wendantang. HepG2 cells were randomly divided into control group， model group， and Huanglian Wendantang-containing serum group. The levels of interleukin-1β （IL-1β） and interleukin-18 （IL-18） in each group were determined by enzyme-linked immunosorbent assay （ELISA）， and the mRNA and protein expression levels of NOD like receptor protein 3 （NLRP3） in each group were determined by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot. In terms of the mechanism， HepG2 cells were randomly divided into control group， empty vector group， NLRP3 overexpression group， empty vector + IR group， empty vector + IR + Huanglian Wendantang-containing serum group， NLRP3 overexpression + IR group， and NLRP3 overexpression + IR + Huanglian Wendantang-contain serum group. GOD-POD method was used to measure the glucose content of each group cells， and calculate the glucose consumption. ELISA was used to determine the release of IL-1β and IL-18 in each group. Real-time PCR and Western blot assay were used to determine the mRNA and protein expressions of cysteinyl aspartate specific proteinase-1 （Caspase-1）， gasdermin D （GSDMD）， and NLRP3. Immunofluorescence assay was used to detect NLRP3， GSDMD， and Caspase -1 expressions. ResultAs compared with the control group， the glucose consumption in the model group was significantly decreased （P<0.01）. As compared with the model group， the increase of the glucose consumption of IR-HepG2 cells was the most significant in the Huanglian Wendantang-containing serum high-dose group （P< 0.01）. As compared with the control group， the IL-1β and IL-18 release levels and the mRNA and protein expressions of NLRP3 in IR-HepG2 cells were significantly increased （P<0.05， P<0.01）. Huanglian Wendantang effectively reduced IR-HepG2 cell supernatant IL-1β， IL-18， and NLRP3 mRNA and protein expressions as compared with the model group （P<0.05， P<0.01）. Overexpression of NLRP3 significantly reduced the cell glucose consumption as compared with the control group and the empty vector group （P<0.01）， and significantly up-regulated the IL-1β and IL-18 levels and the mRNA and protein levels of NLRP3， Caspase-1， and GSDMD as compared with the empty vector + IR group （P<0.05， P<0.01）. Huanglian Wendantang-containing serum effectively reversed the above indicators as compared with the NLRP3 + IR group （P<0.05， P<0.01）. ConclusionHigh fat-induced insulin sensitivity of IR-HepG2 cells is closely related to inflammation and NLRP3 expression. Huanglian Wendantang-containing serum improves IR-HepG2 cell pyroptosis through the targeted inhibition of NLRP3/Caspase-1 signaling pathway， which provides new therapeutic targets for the prevention and treatment of IR and type 2 diabetes mellitus （T2DM）.
