ObjectiveTo investigate the effects and underlying mechanisms of Modified Yupingfeng Nasal Spray （玉屏风加味鼻喷剂， MYNS） on nasal mucosal tissue remodeling in allergic rhinitis （AR） model rats based on the Janus kinase 2 （JAK2）/ signal transducer and activator of transcription 3 （STAT3） signaling pathway. MethodsThe chemical constituents of MYNS were identified and analyzed using liquid chromatography-tandem mass spectrometry （LC-MS/MS）. Network pharmacology and molecular docking were integrated to identify the potential targets and signaling pathways of MYNS in the treatment of AR， and to verify the crucial role of the JAK2/STAT3 pathway. Forty rats were randomly divided into blank group， model group， MYNS group， and mometasone furoate nasal spray group， with 10 rats per group. Except for the blank group， the AR rat model was established by ovalbumin （OVA） induction. After successful modeling， rats in the MYNS group received an intranasal instillation of 50 μl of MYNS at concentration of 1.05 g·ml^-¹ in each nostril， while the mometasone furoate nasal spray group received 50 μl of corresponding spray per nostril， and the model group received 50 μl of normal saline per nostril. Treatments were administered once daily. After 14 consecutive days of intervention， the frequencies of nosal scratching and sneezing in rats within 15 minutes were recorded. Hematoxylin-eosin （HE） staining was used to assess morphological changes in the nasal mucosa and perform pathological scoring. Masson staining was used to evaluate collagen fiber deposition in nasal mucosal tissue and calculate the collagen volume fraction （CVF）. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling （TUNEL） staining was performed to detect apoptosis in nasal mucosal cells and record the number of apoptotic cells. Immunofluorescence assay was used to detect the expression of E-cadherin （E-Cad） in the nasal mucosa. Enzyme-linked immunosorbent assay （ELISA） was used to determine the serum levels of interleukin-4 （IL-4）， interferon-γ （IFN-γ）， histamine （HIS）， immunoglobulin E （IgE）， superoxide dismutase （SOD）， and malondialdehyde （MDA）. Transmission electron microscopy was used to observe the ultrastructure of mitochondria in nasal mucosal epithelial cells. Flow cytometry was used to measure mitochondrial membrane potential （MMP） and reactive oxygen species （ROS） levels. Western Blot was used to determine the protein expression levels of collagen Ⅲ （Collagen Ⅲ）， α-smooth muscle actin （α-SMA）， Bcl-2-associated X protein （Bax）， Caspase-3， JAK2， phosphorylated JAK2 （p-JAK2）， STAT3， and phosphorylated signal transducer and activator of transcription 3 （p-STAT3）. ResultsA total of 626 chemical constituents were identified by LC-MS/MS. Network pharmacology screening identified 450 active ingredients. Nine intersecting components and 39 drug-AR intersecting targets were obtained. KEGG enrichment analysis indicated the involvement of signaling pathways including JAK2/STAT3. The animal experimental results showed that， compared with the blank group， rats in the model group exhibited significantly increased frequencies of nasal scratching and sneezing， as well as elevated CVF and the number of apoptotic cells， while the levels of E-Cad， MMP， and serum IFN-γ and SOD significantly decreased； meanwhile， the serum levels of IL-4， IgE， HIS， ROS， and MDA， along with the protein expression levels of Collagen Ⅲ， α-SMA， Bax， Caspase-3， p-JAK2， and p-STAT3 in the nasal mucosa， significantly increased （P＜0.05）， accompanied by aggravated pathological damage in the nasal mucosa， increased collagen fiber deposition， and abnormal mitochondrial morphology. Compared to the model group， rats in the MYNS group showed improvements in all the aforementioned indicators except for HIS （P＜0.05）， and those in the mometasone furoate nasal spray group showed improvements in all indicators except for IL-4， IgE， and SOD levels （P＜0.05）. ConclusionThe mechanism of MYNS in treating AR may be related to inhibiting the activation of the JAK2/STAT3 signaling pathway， reducing inflammatory responsesand oxidative stress， ameliorating mitochondrial damage， and suppressing nasal mucosal cell apoptosis， thereby improving nasal mucosal tissue pathological remodeling.

Objective    To investigate the perioperative efficacy and safety of all-port robotic lobectomy versus thoracoscopic lobectomy in stageⅠA non-small cell lung cancer. Methods    The clinical data of patients with stageⅠA non-small cell lung cancer who underwent lobectomy with lymph node dissection performed by the same operator in our center from June 2019 to June 2022 were retrospectively analyzed. The patients were divided into a robotic group and a thoracoscopic group according to different procedures. We compared the relevant indexes such as operation time, intraoperative bleeding, number of lymph node dissection stations, number of lymph node dissection, postoperative tube time, postoperative hospitalization time, closed chest drainage volume, postoperative pain, postoperative complications and hospitalization cost between the two groups. Results    There were 83 patients in the robotic group, including 34 males and 49 females with a median age of 60.0 (53.0, 67.0) years, and 94 patients in the thoracoscopic group, including 36 males and 58 females with a median age of 60.5 (54.0, 65.3) years. There was no conversion to thoractomy or death in postoperative 90 days in both groups. No statistical difference was seen in the operation time, total postoperative drainage volume and postoperative complication rates between the two groups (P>0.05). Patients in the robotic group had less intraoperative bleeding (P<0.001), more lymph node dissection stations (P=0.002) and numbers (P=0.005), less postoperative pain (P=0.002), and shorter postoperative time with tubes (P=0.031) and hospital stay (P<0.001). However, the surgery was more expensive in the robotic group (P<0.001). Conclusion    All-port robotic surgery is safe and effective for patients with early-stage non-small cell lung cancer with less intraoperative bleeding, more lymph node dissection, less postoperative pain, and shorter hospital stay compared with the thoracoscopic surgery.

Objective    To analyze and compare the perioperative efficacy difference between full-port Da Vinci robotic surgery and thoracoscopic surgery in patients with mediastinal tumor resection. Methods    The data of 232 patients with mediastinal tumors treated by the same operator in the Department of Thoracic Surgery of the Second Affiliated Hospital of Harbin Medical University were included. There were 103 (44.4%) males and 129 (55.6%) females, with an average age of 49.7 years. According to the surgical methods, they were divided into a robot-assisted thoracic surgery (RATS) group (n=113) and a video-assisted thoracoscopic surgery (VATS) group (n=119). After 1 : 1 propensity score matching, 57 patients in the RATS group and 57 patients in the VATS group were obtained. Results    The RATS group was better than the VATS group in the visual analogue scale pain score on the first day after the surgery [3.0 (2.0, 4.0) points vs. 4.0 (3.0, 5.0) points], postoperative hospital stay time [4.0 (3.0, 5.5) d vs. 6.0 (5.0, 7.0) d] and postoperative catheterization time [2.0 (2.0, 3.0) d vs. 3.0 (3.0, 4.0) d] (all P<0.05). There was no statistical difference between the two groups in terms of intraoperative blood loss, postoperative complications, postoperative thoracic closed drainage catheter placement rate or postoperative total drainage volume (all P>0.05). The total hospitalization costs [51 271.0 (44 166.0, 57 152.0) yuan vs. 35 814.0 (33 418.0, 39 312.0) yuan], operation costs [37 659.0 (32 217.0, 41 511.0) yuan vs. 19 640.0 (17 008.0, 21 421.0) yuan], anesthesia costs [3 307.0 (2 530.0, 3 823.0) yuan vs. 2 059.0 (1 577.0, 2 887.0) yuan] and drug and examination costs [9 241.0 (7 987.0, 12 332.0) yuan vs. 14 143.0 (11 620.0, 16 750.0) yuan] in the RATS group was higher than those in the VATS group (all P<0.05). Conclusion    Robotic surgery and thoracoscopic surgery can be done safely and effectively. Compared with thoracoscopic surgery, robotic surgery has less postoperative pain, shorter tube-carrying time, and less postoperative hospital stay, which can significantly speed up the postoperative recovery of patients. However, the cost of robotic surgery is higher than that of thoracoscopic surgery, which increases the economic burden of patients and is also one of the main reasons for preventing the popularization of robotic surgery.

Objective    To explore the feasibility of decompression without gastric tube after minimally invasive esophageal cancer surgery. Methods    Seventy-two patients who underwent minimally invasive esophageal cancer resection at the Department of Thoracic Surgery, The Second Affiliated Hospital of Harbin Medical University from 2016 to 2018 were selected as a trial group including 68 males and 4 females with an average age of 58.5±7.9 years, who did not use gastric tube for gastrointestinal decompression after surgery. Seventy patients who underwent the same operation from 2013 to 2015 were selected as the control group, including 68 males and 2 females, with an average age of 59.1±6.9 years, who were indwelled with gastric tube for decompression after surgery. We observed and compared the intraoperative and postoperative indicators and complications of the two groups. Results    There were no significant differences between the two groups in operation time, intraoperative blood loss, postoperative level of serum albumin, postoperative nasal jejunal nutrition, whether to enter the ICU postoperatively, death within 30 days after surgery, anastomotic leakage, lung infection, vomiting, bloating or hoarseness (P>0.05). No gastroparesis occurred in either group. Compared with the control group, the recovery time of the bowel sounds and the first exhaust time after the indwelling in the trial group were significantly shorter, and the total hospitalization cost, the incidence of nausea, sore throat, cough, foreign body sensation and sputum difficulty were significantly lower (P<0.05). Conclusion    It is feasible to remove the gastric tube for gastrointestinal decompression after minimally invasive esophageal cancer surgery, which will not increase the incidence of postoperative complications, instead, accelerate the postoperative recovery of patients.

Esophageal cancer is one of the common malignant tumors in China.Although it is currently treated by multidisciplinary treatment,esophageal cancer's prognosis is still poor.The occurrence of esophageal cancer is closely related to the metabolism of trace element zinc.Zinc deficiency can induce the development of esophageal cancer by inducing inflammatory reaction and microRNAs imbalance.Zinc ion can play an important role in esophageal cancer by regulating the activity of ion channel.The formed zinc finger protein can function as an oncogene or a tumor suppressor gene in esophageal cancer.Zinc metabolism is accompanied by complex biological changes in the pathogenesis of esophageal cancer,and multiple mechanisms interact and are closely linked.The article reviews the research results of recent years on the mechanism of zinc deficiency,zinc ion-regulated ion channel and zinc finger protein in the development of esophageal cancer.

This study aimed to evaluate the sensitivity and specificity of the new clinical diagnostic and classification criteria for Kashin-Beck disease (KBD) using six clinical markers: flexion of the distal part of fingers, deformed fingers, enlarged finger joints, shortened fingers, squat down, and dwarfism. One-third of the total population in Linyou County was sampled by stratified random sampling. The survey included baseline characteristics and clinical diagnoses, and the sensitivity and specificity of the new criteria was evaluated. We identified 3,459 KBD patients, of which 69 had early stage KBD, 1,952 had stage I, 1,132 had stage II, and 306 had stage III. A screening test classified enlarged finger joints as stage I KBD, with a sensitivity and specificity of 0.978 and 0.045, respectively. Shortened fingers were classified as stage II KBD, with a sensitivity and specificity of 0.969 and 0.844, respectively, and dwarfism was classified as stage III KBD with a sensitivity and specificity of 0.951 and 0.992, respectively. Serial screening test revealed that the new clinical classification of KBD classified stages I, II, and III KBD with sensitivities of 0.949, 0.945, and 0.925 and specificities of 0.967, 0.970, and 0.993, respectively. The screening tests revealed that enlarged finger joints, shortened fingers, and dwarfism were appropriate markers for the clinical diagnosis and classification of KBD with high sensitivity and specificity.

Objective    To explore the risk factors and short-term clinical effect of conversion to open thoracotomy during thoracoscopic lobectomy for lung cancer patients. Methods    We retrospectively analyzed the clinical data of 423 lung cancer patients who were scheduled for thoracoscopic lobectomy between March 2011 and November 2015.There were 252 males and 171 females at median age of 60 (24-83) years. According to the patients who were and were not converted to thoracotomy, they were divided into a conversion group (378 patients) and a video-assisted thoracic surgery group (a VATS group, 45 patients). Then, clinical data of two groups were compared, and the risk factors and short-term clinical effect of unplanned conversions to thoracotomy were analyzed. Results    Lymph nodes of hilar or/and interlobar fissure closely adhered to adjacent vessels and bronchi was the most common cause of unexpected conversions to thoracotomy in 15 patients (33.3%), followed by sleeve lobectomy in 11(24.4%) patients, uncontrolled hemorrhage caused by intraoperative vessel injury in 8 patients, tumor invasion or extension in 5 patients, difficulty of exposing bronchi in 3 patients, close adhesion of pleural in 2 patients, incomplete interlobar fissure in 1 patient. Conversion did translate into higher overall postoperative complication rate (P=0.030), longer operation time (P<0.001), more intraoperative blood loss (P<0.001). In the univariable analysis, the type of operation, the anatomical site of lung cancer, the lymph node enlargement of hilar in CT and the low diffusion capacity for carbon monoxide (DLCO) were related to conversion. Logistic regression analysis showed that the independent risk factors for conversion were sleeve lobectomy (OR=5.675, 95%CI 2.310–13.944, P<0.001), the lymph node enlargement of hilar in CT (OR=3.732, 95%CI 1.347–10.341, P=0.011) and DLCO≤5.16 mmol/(min·kPa)(OR=3.665, 95%CI 1.868–7.190, P<0.001). Conclusions    Conversion to open thoracotomy during video-assisted thoracic surgery lobectomy for lung cancer does not increase mortality, and it is a measure of reducing the risk of surgery. Therefore, with high-risk patients who may conversion to thoracotomy, the surgeon should be careful selection for VATS candidate. And, if necessary, the decision to convert must be made promptly to reduce short-term adverse outcome.
