BACKGROUND: Lung cancer is currently the most prevalent malignancy and the leading cause of cancer deaths worldwide. Although the early stage non-small cell lung cancer (NSCLC) presents a relatively good prognosis, a considerable number of lung cancer cases are still detected and diagnosed at locally advanced or late stages. Surgical treatment combined with perioperative multimodality treatment is the mainstay of treatment for locally advanced NSCLC and has been shown to improve patient survival. Following the standard methods of neoadjuvant therapy, perioperative management, postoperative adjuvant therapy, and other therapeutic strategies are important for improving patients' prognosis and quality of life. However, controversies remain over the perioperative management of NSCLC and presently consensus and standardized guidelines are lacking for addressing critical clinical issues in multimodality treatment. METHODS: The working group consisted of 125 multidisciplinary experts from thoracic surgery, medical oncology, radiotherapy, epidemiology, and psychology. This guideline was developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The clinical questions were collected and selected based on preliminary open-ended questionnaires and subsequent discussions during the Guideline Working Group meetings. PubMed, Web of Science, Cochrane Library, Scopus, and China National Knowledge Infrastructure (CNKI) were searched for available evidence. The GRADE system was used to evaluate the quality of evidence and grade the strengths of recommendations. Finally, the recommendations were developed through a structured consensus-building process. RESULTS: The Guideline Development Group initially collected a total of 62 important clinical questions. After a series of consensus-building conferences, 24 clinical questions were identified and corresponding recommendations were ultimately developed, focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assement, and follow-up protocols for NSCLC. CONCLUSIONS This guideline puts forward reasonable recommendations focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assessment, and follow-up protocol of NSCLC. It standardizes perioperative multimodality treatment and provides guidance for clinical practice among thoracic surgeons, medical oncologists, and radiotherapists, aiming to reduce postoperative recurrence, improve patient survival, accelerate recovery, and minimize postoperative complications such as atelectasis.

Objective:To explore the repair methods of complex facial defect wounds involving paranasal sinuses and their clinical effectiveness.Methods:A retrospective observational study was conducted. From January 2020 to May 2022, 5 patients admitted to the Department of Burns and Plastic Surgery of Xiangya Hospital of Central South University and 4 patients admitted to the Department of Burns and Plastic Surgery of Chenzhou First People's Hospital with complex facial defect wounds involving paranasal sinuses met the inclusion criteria, including 6 males and 3 females, aged 35-69 years, including 4 patients with titanium mesh exposure combined with paranasal sinuses injury and 5 patients with tumor involving paranasal sinuses. After an adequate assessment of the damage by a multiple discipline team, titanium mesh removal, paranasal sinus debridement, and paranasal sinus mucosa removal were performed in patients with exposed titanium mesh, and radical tumor resection was performed in patients with tumors, with postoperative skin and soft tissue defects areas of 5.0 cm×2.5 cm to 18.0 cm×7.0 cm, anterior paranasal sinus wall defects/absence areas of 3 cm×2 cm to 6 cm×4 cm, and sinus cavity depths of 1 to 4 cm. Depending on the perforator course of the descending branch of the lateral circumflex femoral artery, the anterolateral femoral chimeric flap or anterolateral femoral myocutaneous flap (with flap area of 9 cm×4 cm to 19 cm×8 cm, muscle size of 5 cm×3 cm×3 cm to 11 cm×6 cm×3 cm) was transplanted to repair the defect, and the donor site wound was sutured directly. The type of tissue flap transplanted, the blood vessel of the recipient area, and the vascular anastomosis way during the operation, the recovery of the donor and recipient areas and the occurrence of complications after operation were observed. The appearance and blood supply of the recipient area and the recurrence of ulcers and tumors were followed up.Results:The anterolateral femoral myocutaneous flap transplantation was performed in 6 patients, and the anterolateral femoral chimeric flap transplantation was performed in 3 patients. The blood vessels in recipient areas were facial arteries and veins in 3 cases and superficial temporal arteries and veins in 6 cases. The superficial temporal arteries and veins were bridged with blood vessels in tissue flaps by flow-through way in 2 patients, and end-to-end anastomosis of blood vessels in donor and recipient areas was performed in 7 patients. After operation, all the tissue flaps survived, and the facial defect wounds were well repaired without cerebrospinal fluid leakage or paranasal sinus secretion leakage, no intracranial infection occurred, and the wounds in donor areas were healed well. Follow-up of 6-35 months after operation showed that all the patients had good blood supply in the recipient area, and the shape was acceptable; 4 patients with exposed titanium mesh had no recurrence of ulceration, and 5 patients with tumor had no local tumor recurrence or metastasis.Conclusions:Based on an adequate assessment of the extent of paranasal sinuses involved in the facial wound and the nature of the defect, good clinical effects can be achieved by using the anterolateral femoral muscle flap or the anterolateral femoral chimeric flap transplantation to repair complex facial defect wounds with open paranasal sinuses.

OBJECTIVE: To observe the clinical effect of acupuncture for delayed sleep-wake phase disorder (DSWPD). METHODS: A total of 84 patients with DSWPD were randomized into an observation group (42 cases, 2 cases dropped off) and a control group (42 cases, 3 cases dropped off). On the basis of sleep hygiene education, acupuncture was applied at Shenmai (BL 62), Zhaohai (KI 6), Hegu (LI 4), Taichong (LR 3), Zusanli (ST 36) and Sanyinjiao (SP 6) in the observation group, while placebo acupuncture was applied at the same acupoints in the control group. The treatment lasted for 8 weeks, once every other day, 3 times a week in the 1st to 4th weeks; once every 3 days, 2 times a week in the 5th to 8th weeks. Before and after treatment, the actigraphy (ACT) indexes of objective sleep (total time of stay in bed, total sleep time, sleep efficiency, the number of awakenings and the wake time after falling asleep) and plasma cortisol (CORT) level were observed; before and after treatment and in follow-up of 1, 3 months after treatment, the scores of morningness-eveningness questionnaire (MEQ), insomnia severity index (ISI), fatigue severity scale (FSS) and Epworth sleepiness scale (ESS) were observed in the two groups. RESULTS: Compared before treatment, the total sleep time was prolonged, the sleep efficiency was improved, the number of awakenings was reduced, and the wake time after falling asleep was shortened after treatment in the observation group (P<0.01, P<0.05), and those in the observation group after treatment were superior to the control group (P<0.01, P<0.05). Compared before treatment, the MEQ scores after treatment in both groups and in the follow-up of 1, 3 months after treatment in the observation group were increased (P<0.01), and the MEQ score of each time point after treatment in the observation group was higher than the control group (P<0.01). The scores of ISI, FSS and ESS after treatment, and the scores of ISI、ESS in follow-up of 1, 3 months after treatment in the observation group were decreased compared with those before treatment (P<0.01, P<0.05), and in the observation group, the scores of ISI, FSS and ESS of each time point after treatment were lower than those in the control group (P<0.01, P<0.05). After treatment, the plasma CORT level in the observation group was decreased compared with that before treatment and that in the control group (P<0.01, P<0.05). CONCLUSION Acupuncture can improve the sleep and wake phase of patients with DSWPD, improve sleep quality and daytime function, and its mechanism may be related to the down-regulation of plasma CORT level.

Objective:To observe the characteristics of early changes in choroidal thickness and choroidal microvascular morphology in the macula of patients with systemic lupus erythematosus (SLE) using swept-source optical coherence tomography angiography (OCTA).Methods:A cross-sectional study was conducted.Thirty-seven patients (37 eyes) who were diagnosed with SLE without obvious ocular symptoms in Hebei General Hospital from January 2022 to July 2022 were enrolled in this study as a SLE group.At the same time, 35 normal adults (35 eyes) matched with age and sex were included as a control group.Swept-source OCT was used to perform a 9 mm×9 mm radial scan of the macular region of subjects to obtain the average choroidal thickness of the macular central concave area, the paracentral concave area (1-3 mm), and the pericentral concave area (3-6 mm). OCTA was used to perform a 3 mm×3 mm scan of the macular region and images of retinal superficial capillary plexus (SCP) and deep capillary plexus (DCP) blood flow density, choroidal capillary plexus (CC) blood flow density, and microvascular blood flow in the macular region were obtained and binarized using ImageJ software (Phansalkar method) to calculate the choroidal capillary flow void area (FDa) and percentage of flow deficits (FD%). The study protocol followed the Declaration of Helsinki and was approved by the Ethics Committee of Hebei General Hospital (No.202310). Informed consent was obtained from all subjects.Results:The choroidal thickness of the subfoveal region in SLE group was (268.73±81.67)μm, which was significantly higher than (230.14±68.14) μm of control group ( t=2.170, P=0.033). The blood flow density of SCP, DCP and CC in the macular central zone area of SLE group were (16.58±3.90)%, (14.25±3.15)% and (51.80±4.27)%, respectively, which were significantly lower than (20.55±4.41)%, (16.57±3.74)% and (54.33±3.41)% of control group ( t=-4.043, -2.851, -2.763; all at P<0.05). The FDa and FD% in SLE group were 3.43(3.25, 3.56)mm 2 and 38.11%(36.13%, 39.52%), which were greater than 3.25(3.21, 3.32)mm 2 and 36.11%(35.64%, 36.84%) of control group, and the differences were statistically significant ( Z=-3.470, -3.476; both at P<0.05). Conclusions:OCTA can detect an increase in choroidal thickness and a decrease in blood flow density of CC in eyes with SLE without obvious ocular symptoms.

Achyranthes bidentata Blume is widely used as a traditional Chinese medicine with the effects of nourishing the liver and kidneys and strengthening muscles and bones. In this work, a rapid and simple strategy was developed for characterizing phytoecdysteroids by ultra-high-performance liquid chromatography coupled with liner ion trap-Orbitrap mass spectrometry using electrospray ionization in the negative mode. As a result, 47 phytoecdysteroids were unambiguously or tentatively characterized. Among them, seven known compounds were identified according to the reference standards along with molecular formula, retention time and fragmentation patterns, while others were mostly potential new compounds. Through targeted isolation, the structures of three new compounds were determined by NMR spectra, which were consistent with LC-MS characterization. The present study provides an efficient method to deeply characterize phytoecdysteroids.

OBJECTIVES: To study the effect of sex on the clinical outcome of extremely preterm infants (EPIs)/extremely low birth weight infants (ELBWIs) by propensity score matching. METHODS: A retrospective analysis was performed for the medical data of 731 EPIs or ELBWIs who were admitted from January 1, 2011 to December 31, 2020. These infants were divided into two groups: male and female. A propensity score matching analysis was performed at a ratio of 1:1. The matching variables included gestational age, birth weight, percentage of withdrawal from active treatment, percentage of small-for-gestational-age infant, percentage of use of pulmonary surfactant, percentage of 1-minute Apgar score ≤3, percentage of mechanical ventilation, duration of mechanical ventilation, percentage of antenatal use of inadequate glucocorticoids, and percentage of hypertensive disorders in pregnancy. The two groups were compared in the incidence rate of main complications during hospitalization and the rate of survival at discharge. RESULTS: Before matching, compared with the female group, the male group had significantly higher incidence rates of neonatal respiratory distress syndrome, bronchopulmonary dysplasia (BPD), severe intraventricular hemorrhage, periventricular leukomalacia, necrotizing enterocolitis, and patent ductus arteriosus (P<0.05), while after matching, the male group only had a significantly higher incidence rate of BPD than the female group (P<0.05). There was no significant difference in the rate of survival at discharge between the two groups before and after matching (P>0.05). CONCLUSIONS Male EPIs/ELBWIs have a higher risk of BPD than female EPIs/ELBWIs, but male and female EPIs/ELBWIs tend to have similar outcomes.

Objective::To explore the risk factors and pregnancy outcomes in women with a history of cesarean section complicated by placenta accreta (PA).Methods::This case-control study included clinical data from singleton mothers with a history of cesarean section in 11 public tertiary hospitals in seven provinces of China between January 2017 and December 2017. According to the intraoperative findings after delivery, the study population was divided into PA and non-PA groups. We compared the pregnancy outcomes between the two groups, used multivariate logistic regression to analyze the risk factors for placental accreta.Results::For this study we included 11,074 pregnant women with a history of cesarean section; and of these, 869 cases were in the PA group and 10,205 cases were in the non-PA group. Compared with the non-PA group, the probability of postpartum hemorrhage (236/10,205, 2.31% vs. 283/869, 32.57%), severe postpartum hemorrhage (89/10,205, 0.87% vs. 186/869, 21.75%), diffuse intravascular coagulation (3/10,205, 0.03% vs. 4/869, 0.46%), puerperal infection (33/10,205, 0.32% vs. 12/869, 1.38%), intraoperative bladder injury (1/10,205, 0.01% vs. 16/869, 1.84%), hysterectomy (130/10,205, 1.27% vs. 59/869, 6.79%), and blood transfusion (328/10,205,3.21 % vs. 231/869,26.58%) was significantly increased in the PA group ( P < 0.05). At the same time, the neonatal birth weight (3250.00 (2950.00-3520.00) g vs. 2920.00 (2530.00-3250.00) g), the probability of neonatal comorbidities (245/10,205, 2.40% vs. 61/869, 7.02%), and the rate of neonatal intensive care unit admission (817/10,205, 8.01% vs. 210/869, 24.17%) also increased significantly ( P < 0.05). Weight (odds ratio ( OR)= 1.03, 95% confidence interval ( CI): 1.01-1.05)), parity ( OR= 1.18, 95% CI: 1.03-1.34), number of miscarriages ( OR= 1.31, 95% CI: 1.17-1.47), number of previous cesarean sections ( OR= 2.57, 95% CI: 2.02-3.26), history of premature rupture of membrane ( OR= 1.61, 95% CI: 1.32-1.96), previous cesarean-section transverse incisions ( OR= 1.38, 95% CI: 1.12-1.69), history of placenta previa ( OR= 2.44,95% CI: 1.50-3.96), and the combination of prenatal hemorrhage ( OR= 9.95,95% CI: 8.42-11.75) and placenta previa ( OR= 91.74, 95% CI: 74.11-113.56) were all independent risk factors for PA. Conclusion::There was an increased risk of adverse outcomes in pregnancies complicated by PA in women with a history of cesarean section, and this required close clinical attention. Weight before pregnancy, parity, number of miscarriages, number of previous cesarean sections, history of premature rupture of membranes, past transverse incisions in cesarean sections, a history of placenta previa, prenatal hemorrhage, and placenta previa were independent risk factors for pregnancies complicated with PA in women with a history of cesarean section. These independent risk factors showed a high value in predicting the risk for placentab accreta in pregnancies of women with a history of cesarean section.

Objective:To explore the distribution characteristics of respiratory pathogens in patients with community-acquired pneumonia in Lianyungang.Methods:A total of 612 patients admitted to the second people′s Hospital of Lianyungang City because of community-acquired pneumonia (CAP) in 2019 were selected as subjects. Sputum or pharyngeal swabs were collected to extract nucleic acids, and 13-fold nucleic acids of respiratory pathogens were detected by PCR capillary electrophoresis fragment analysis. SPSS statistical software and GraphPad5.0 statistical mapping software were used for statistical analysis.Results:The physical examination rate of respiratory pathogens in the adult group was 82.0% in winter, 48.4% in spring, 28.0% in autumn, 20.0% in summer, χ 2=38.473, P=0.000. The positive rate of nucleic acid detection was significantly different in different seasons, among which the physical examination rate of respiratory pathogens in winter was the highest. The physical examination rate of respiratory pathogens in the juvenile group was 86.0% in spring, 76.2% in winter, 71.3% in summer and 66.7% in autumn, χ 2=7.946, P=0.047 . The positive rate of nucleic acid detection was calculated according to gender grouping. The comparison of nucleic acid positive rate between adult group and juvenile group in different seasons: 86.0% vs 48.4% in spring, χ 2=19.436, P=0.000; 71.3% vs 20.0% in summer, χ 2=22.180, P=0.000; 66.7% vs 28.0% in autumn, χ 2=13.485, P=0.000; 76.2% vs 82.0% in winter, χ 2=0.758, P=0.384. Except in winter, the detection rate of nucleic acid of pathogens in the juvenile group was significantly higher than that in the adult group. Conclusions:The nucleic acid detection rate and etiological distribution characteristics of respiratory pathogens are different in patients with community-acquired pneumonia in different seasons and different age groups. 13 kinds of multiple detection methods of respiratory pathogens can provide favorable laboratory data support for the diagnosis and treatment of clinical CAP patients.

Objective:To investigate the contamination status of SARS-CoV-2 in imported frozen seafood from a Russia cargo ship in Qingdao and to analyze the risk factors for infection in local stevedores.Methods:The method of "two-stage, full coverage and mixed sampling" was used to collect the seafood packaging samples for the nucleic acid detection of SARS-CoV-2 by real-time fluorescent quantitative RT-PCR. A unified questionnaire was designed to investigate 71 stevedores in two shifts through telephone interview. The stevedores were divided into two groups, with 23 in the shit with two infections was group A and 48 in the shift without infection was group B. Software Epi Info7.2 was used to identify the risk factors for SARS-CoV-2 infections in the stevedores.Results:In the frozen seafood from a Russia cargo ship, the total positive rate of SARS-CoV-2 nucleic acid in the frozen seafood was 11.53% (106/919). The positive rate of SARS-CoV-2 nucleic acid in the frozen seafood unloaded by group A (14.29%,70/490) was significantly higher than that in the frozen seafood unloaded by group B (8.39%,36/429)( χ2=7.79, P=0.01) and the viral loads detected in the frozen seafood unloaded by group A were higher than those detected in the frozen seafood unloaded by group B. The scores of personal protection and behaviors in the stevedores in group A were significantly lower than those in group B ( P<0.05), and toilet use, smoking and improper hand washing before meals were the risk factors for the infection. Conclusions:The imported frozen seafood was contaminated by SARS-CoV-2 and the contamination distribution was uneven. Supervision and management of personal occupational protection and behaviors of workers engaged in imported frozen food transportation should be strengthened. It is suggested that a closed-loop monitoring and management system for the whole process of "fishing-transport- loading/unloading" should be established by marine fishery authority.
