Objective: To explore the method and effect of endoscopic assisted functional rhinoplasty for patients with deviated nose and deviated nasal septum, which achieve correction of nasal morphology and ventilation dysfunction. Methods: The clinical data of 226 patients with deviated nose and deviated nasal septum from June 2009 to February 2022 who were treated by endoscopic assisted functional rhinoplasty in the Affiliated Hospital of Qingdao University were analyzed retrospectively. There were 174 males and 52 females, with the age ranging from 7 to 67 years old. The effect was evaluated by subjective and objective evaluation methods. SPSS 27.0 software was used for statistical analysis. Results: All patients were followed up for 6 to 24 months, 174 cases were cured (174/226, 76.99%), 52 cases were effective (52/226, 23.01%), and the total effective rate was 100% (226/226). The difference between preoperative and postoperative facial appearance deviation was statistically significant ((6.84±2.25)mm vs (1.82±1.05)mm, t=38.94, P<0.001), and the nasal ventilation function of all patients was improved. Conclusions: Endoscopic assisted functional rhinoplasty for the patients with deviated nose combined with deviated nasal septum has the advantages of clear surgical field, fewer complications, and good result. It can achieve the purpose of simultaneous correction of nasal and ventilation dysfunction, which is recommended for popularizing in clinical application.

Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

OBJECTIVE: To investigate the mechanism of Tojapride, a Chinese herbal formula extract, on strengthening the barrier function of esophageal epithelium in rats with reflux esophagitis (RE). METHODS: Ten out of 85 SD rats were randomly selected as the sham group (n10), and 75 rats were developed a reflux esophagitis model (RE) by the esophageal and duodenal side-to-side anastomosis. Fifty successful modeling rats were divided into different medicated groups through a random number table including the model, low-, medium-, and high-dose of Tojapride as well as omeprazole groups (n10). Three doses of Tojapride [5.73, 11.46, 22.92 g/(kg•d)] and omeprazole [4.17 mg/(kg•d)] were administrated intragastrically twice daily for 3 weeks. And the rats in the sham and model groups were administered 10 mL/kg distilled water. Gastric fluid was collected and the supernatant was kept to measure for volume, pH value and acidity. Esophageal tissues were isolated to monitor the morphological changes through hematoxylin-eosin (HE) staining, and esophageal epithelial ultrastructure was observed by transmission electron microscopy. The expressions of nuclear factor kappa-light-chain-enhancer of activated B cells p65 (NF-KBp65), κB kinase beta (IKKß), occludin, and zonula occludens-1 (ZO-1) in the esophageal tissues were measured by immunohistochemistry and Western blot, respectively. RESULTS: The gastric pH value in the model group was significantly lower than the sham group (P<0.05). Compared with the model group, gastric pH value in the omeprazole and medium-dose of Tojapride groups were significantly higher (P<0.05). A large area of ulceration was found on the esophageal mucosa from the model rats, while varying degrees of congestion and partially visible erosion was observed in the remaining groups. Remarkable increase in cell gap width and decrease in desmosome count was seen in RE rats and the effect was reversed by Tojapride treatment. Compared with the sham group, the IKKß levels were significantly higher in the model group (P<0.05). However, the IKKß levels were down-regulated after treatment by all doses of Tojapride (P<0.01 or P<0.05). The occluding and ZO-1 levels decreased in the model group compared with the sham group (Ps0.01 or Ps0.05), while both indices were significantly up-regulated in the Tojapride-treated groups (P<0.01 or P<0.05). CONCLUSIONS Tojapride could improve the pathological conditions of esophageal epithelium in RE rats. The underlying mechanisms may involve in down-regulating the IKKß expression and elevating ZO-1 and occludin expression, thereby alleviating the inflammation of the esophagus and strengthening the barrier function of the esophageal epithelium.

Objective     To identify the risk factors for postoperative recurrence of peripheral solid small-nodule lung cancer (PSSNLC) (T≤2 cm), and to explore the effects of surgery types on prognosis. Methods     We extracted data from Western China Lung Cancer Database (WCLCD), a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University, and Surveillance, Epidemiology, and End Results (SEER)  database for peripheral solid small-nodule lung cancer patients (T≤2 cm N0M0, stageⅠ) who underwent surgery between 2005 and 2016. We used univariable and multivariable logistic regression to analyze risk factors for recurrence of PSSNLC. We applied propensity-score matching to compare the long-term results of segmentectomy and lobectomy, as well as the survival of patients from WCLCD and SEER. We finally included 4 800 patients with PSSNLC (T≤2 cm N0M0)(WCLCD: SEER=354∶4 446). We matched 103 segmentectomies and 350 lobectomies in T≤1 cm, and 280 segmentectomies and 1 067 lobectomies in 1 cm

Objective To explore the effect of long noncoding RNA-ATB (LncRNA-ATB) on phenotypic transition and proliferation of human peritoneal mesothelial cells (HPMCs) induced by high glucose.Methods HPMCs used in experiment were divided into three groups:control group,mannitol group and hypertonic glucose group.HPMCs in control group received no treatment,and in hypertonic glucose group and mannitol group were treated with 50mmol/L D-glucose and isotonic mannitol for 72 hours,respectively.Real-time PCR was employed to detect the mRNA expression of LncRNA-ATB,E-cadherin,α-smooth muscle actin (α-SMA),connective tissue growth factor (CTGF),Cyclin D1,cyclin dependent kinase inhibitor 4 (CDK4),protein 27 (p27)and proliferating cell nuclear antigen (PCNA).Western blotting was performed to detect the proteins expression of E-cadherin,α-SMA,CTGF,Cyclin D1,CDK4,p27 and PCNA,and flow cytometry was used to test the cell cycle.Lentivirus artifice was used to up-or down-regulate the expression of LncRNA-ATB in untreated HPMCs.Real-time PCR was employed to detect the mRNA expression of E-cadherin,α-SMA and CTGF,Western blotting was performed to detect the proteins expression of E-cadherin,α-SMA and CTGF,and flow cytometry was used to test the cell cycle.Results It is revealed by Real-time PCR,Western blotting and flow cytometry that the expressions increased of LncRNA-ATB,α-SMA,CTGF,Cyclin D1,CDK4 and PCNA induced by hypertonic glucose,and decreased of E-cadherin and p27 (P＜0.05).Up-regulation of LncRNA-ATB promoted HPMCs phenotypic transition and proliferation,while down-regulation alleviated HPMCs phenotypic transition and proliferation.Conclusion Hypertonic glucose may accelerate HPMCs phenotypic transition and proliferation by up-regulating the expression of LncRNA-ATB.

OBJECTIVETo explore the roles of PKCβ/P66Shc oxidative stress signal pathway in mediating hyperoxia-induced reactive oxgen species (ROS) production in alveolar epithelial cells (A549) and the protective effects of PKCβ inhibitor on hyperoxia-induced injuries of alveolar epithelial cells.

METHODSA549 cells were cultured in vitro and randomly divided into three groups: control, hyperoxia and PKCβ inhibitor LY333531 treatment. The hyperoxia group was exposed to a mixture of O2 (950 mL/L) and CO2 (50 mL/L) for 10 minutes and then cultured in a closed environment. The LY333531 group was treated with PKCβ inhibitor LY333531 of 10 µmol/L for 24 hours before hyperoxia induction. Cells were collected 24 hours after culture and the levels of PKCβ, Pin1, P66Shc and P66Shc-Ser36 were detected by Western blot. The intracellular translocation of P66Shc, the production of ROS and cellular mitochondria membrane potential were measured using the confocal microscopy.

RESULTSCompared with the control group, the levels of PKCβ, Pin1, P66Shc and P-P66Shc-Ser36 in A549 cells 24 hours after culture increased significantly in the hyperoxia group. These changes in the hyperoxia group were accompanied with an increased translocation rate of P66Shc from cytoplasm into mitochondria, an increased production of mitochondrial ROS, and a reduced mitochondrial membrane potential. Compared with the hyperoxia group, the levels of Pin1, P66Shc and P66Shc-Ser36 in A549 cells, the translocation rate of P66Shc from cytoplasm into mitochondria and the production of mitochondrial ROS decreased significantly, while the mitochondrial membrane potential increased significantly in the LY333531 treatment group. However, there were significant differences in the above mentioned measurements between the LY333531 treatment and control groups.

CONCLUSIONSHyperoxia can increase the expression of PKCβ in alveolar epithelial cells and production of mitochondrial ROS and decrease mitochondrial membrane potential. PKCβ inhibitor LY333531 can partially disrupt these changes and thus alleviate the hyperoxia-induced alveolar epithelial cell injury.

It is held by some of the researches that the "16 collaterals" is composed of the "15 collaterals" and "the major collateral of stomach". And it is included into the textbook that Xuli, the major collateral of stomach, is the pulsation point at the cardiac region. Xuli is often explained as the empty portion of the human body by many researches. Through analysis and summarization of the related theory of the major collateral of stomach, the above mentioned opinion is discussed. And the understanding on the major collateral of stomach is deepened. As a result, it is concluded that count the major collateral of stomach into the 16 collaterals together with the 15 collaterals is inadvisable. The real pulsation point at the cardiac region locates under the left breast. And the real meaning of Xuli is "extending in all directions".
