ABSTRACT

Objective @#To examine the association between acute exposure to traffic-related air pollutants (TRAP) NOX and NO2 and outpatient visits of pediatric respiratory diseases. @*Methods @#Data regarding outpatient visits to Department of Respiratory Diseases of Beijing Children's Hospital from 2015 to 2020 were collected, and the concentrations of nitrogen oxides (NOX), nitrogen dioxide (NO2) and other TRAP were collected from the surveillance sites assigned by the Peking University Health Science Center. A time-stratified case-crossover design was employed, and a conditional logistic regression model was created to examine the association between NOX and NO2 acute exposure and outpatient visits of pediatric respiratory diseases. @*Results @#The daily mean outpatient visits of pediatric respiratory diseases were 571 (interquartile range, 554) person-times among children at ages of 0 to 14 years in Beijing Children's Hospital from 2015 to 2020, and the daily mean outpatient visits for upper respiratory tract infections (URI), bronchitis, and pneumonia were 265 (interquartile range, 282), 143 (interquartile range, 178) and 128 (interquartile range, 120) person-times, respectively. The daily mean concentrations of atmospheric NOX and NO2 were 67.8 (interquartile range, 50.7) and 49.3 (interquartile range, 30.7) μg/m3, respectively. Conditional logistic regression analysis showed the largest lagged effect of NOX and NO2 on pediatric respiratory diseases at cumulative lags of 0 to 7 days. An increase in NOX concentrations by an interquartile range resulted in the excess risks of URI, bronchitis and pneumonia by 6.87% (95%CI: 6.37%-7.38%), 7.25% (95%CI: 6.51%-7.99%), and 5.51% (95%CI: 4.69%-6.33%), and an increase in NO2 concentrations by an interquartile range resulted in excess risks of URI, bronchitis and pneumonia by 5.71% (95%CI: 5.12%-6.31%), 5.32% (95%CI: 4.51%-6.14%), and 4.83% (95%CI: 3.91%-5.75%), respectively. NOX and NO2 presented a more remarkable effect on outpatient visits of pediatric respiratory diseases among children at ages of over 5 years. @*Conclusion @#NOx and NO2 acute exposure may increase the outpatient visits of pediatric respiratory diseases.

ABSTRACT

@#Tumor immunotherapy is a therapeutic modality that uses immunological principles and methods to activate and enhance the body''s immune system to generate immune response for the removal of tumour cells. Many new immunotherapeutic agents have demonstrated effective anti-tumour capabilities, yet their clinical use is challenging due to the complex mechanisms of tumour immune escape. Meanwhile, these drugs would accumulate in different tissues and organs in the human body and be unable to achieve precise and specific targeting therapeutic effects, resulting in serious immune-related adverse effects, which greatly hinders the clinical potential of immunotherapy.Nanodrug delivery systems can deliver immunotherapeutic drugs to target tissues or specific immune cells precisely, thereby enhancing immune effects and reducing side effects.This paper reviews the research progress of nanodrug delivery systems in tumour immunotherapy in recent years based on the regulatory mechanism of the anti-tumour immune response, with a prospect of the challenges and development in this field.

ABSTRACT

Objective: To investigate the epidemiological characteristics of pneumoconiosis deaths in Putuo District of Shanghai, and to provide evidence for prevention and management of pneumoconiosis in the future. Methods: In June 2021, the data of 263 patients with pneumoconiosis who died from January 1961 to December 2020 in Putuo District of Shanghai were retrospectively analyzed. Trend χ(2) test, analysis of variance and Spearman rank correlation methods were used to analyze the basic information, age of exposure to dust, promotion period, course of disease and direct cause of death of patients with pneumoconiosis. Results: Among the 263 cases of pneumoconiosis patients who died in Putuo District of Shanghai from 1961 to 2020, 260 cases (98.86%) were male. The main types of pneumoconiosis were foundry worker pneumoconiosis (53.23%, 140/263) and silicosis (43.73%, 115/263). The main types of pneumoconiosis were sand cleaner (36.50%, 96/263). The age of onset was (53.42±10.13) years old, the age of death was (76.14±9.12) years old, and the age of exposure to dust was (20.91±8.99) years. The duration of dust exposure was negatively correlated with the duration of disease (r(s)=-0.24, P<0.001). With the increase of pneumoconiosis stage, the mortality of silicosis and foundry worker pneumoconiosis also showed an increasing trend (χ(2)(trend)=4.22, 3.87, P=0.040, 0.049). 31.94% (84/263) of pneumoconiosis patients died directly from pneumoconiosis, ranking first among the direct causes of death. Conclusion: The death cases of pneumoconiosis in Putuo District of Shanghai are mainly foundry worker pneumoconiosis and silicosis, and pneumoconiosis is the main cause of death.

ABSTRACT

Objective: To explore the reasonable time of prophylactic thyroidectomy for RET gene carriers in multiple endocrine neoplasia(MEN) 2A/2B families. Methods: From May 2015 to August 2021, RET gene carriers in MEN2A/MEN2B families were dynamically followed up at the Department of Thyroid Head and Neck Surgery, Beijing Tongren Hospital of Capital Medical University. The high-risk patients were encouraged to undergo prophylacitc total thyroidectomy according to the principle of "graded early warning system", namely the evaluation of gene detection, calcitonin value and ultrasound examination successively. Seven cases underwent the surgery, including 3 males and 4 females, aged from 7 to 29 years. According to the risk stratification listed in the guidelines of the American Thyroid Association in 2015, there were 2 cases of the highest risk, 2 cases of the high risk and 3 cases of the modest risk. Calcitonin index remained within the normal range in 3 cases and elevated in 4 cases before operation. All 7 patients underwent thyroidectomy with lymph node dissection of the level Ⅵ performed in 4 patients. Results: The time from suggestion to operation was 2 to 37 months, with an average of 15.1 months. The 6 patients were medullary thyroid carcinoma and 1 case with C-cell hyperplasia. The follow-up time was 2 to 82 months, with an average of 38.4 months. Postoperative serum calcitonin levels of all cases decreased to normal level, with biochemical cure. There was no sign of recurrence on ultrasound examination. All 7 patients had no serious complications, no obvious thyroid dysfunction. Their height, weight and other indicators of pediatric patients were similar to those of their peers, with normal growth and development. Conclusion: For healthy people with MEN2A/MEN2B family history, prophylactic thyroidectomy can be carried out selectively based on the comprehensive evaluation of "graded early warning system" with strict screening and close monitoring.

ABSTRACT

The human resource management of organ donation coordinators in China is still in its infancy stage, plagued by such problems as unclear career orientation, poor management and unclear career planning. In March 2010, a tertiary public hospital was approved as a medical institution in a national pilot province for organ donation. In recent years, the hospital had kept exploring human resource management of coordinators and established a relatively complete management mode for organ donation coordinators. This mode featured the establishment of full-time recruitment positions, development of human resource management plans, refinement of job descriptions, establishment of performance evaluation plans, optimization of assessment and incentive mechanisms, and innovation of talent cultivation modes. The management practice had achieved certain results, ensuring the sustainable development of hospital organ donation operation, and providing a reference for the scientific and standardized development of organ donation and transplantation in China.

ABSTRACT

Parkinson′s disease (PD) is one of the neurodegenerative diseases with high incidence in middle-aged and elderly people, and its prodromal stage lasts for several years to decades, markers of disease progression in prodromal stage are important basis for early recognition and diagnosis of PD. Current studies have shown that rapid eye movement sleep behavior disorder (RBD) is the specific clinical prodromal symptoms of PD, and has some of the same mechanisms as PD. Part of the same mechanisms develop regularly in the process of RBD converting to PD, which may produce valuable prodromal markers of PD. This paper reviews the common mechanisms of PD and RBD, in order to provide some ideas for the early clinical diagnosis and treatment of PD.

ABSTRACT

Objective:To evaluate the accuracy of the domestic "Skywalker" surgical robot in implementing personalized lower limb alignment reconstruction scheme in total knee arthroplasty (TKA) and the short-term clinical outcome of robotic assisted TKA.Methods:From September 2020 to January 2021, the data of patients who received surgical robot assisted TKA in 5 clinical centers in China (Shanghai Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine, Southwest Hospital affiliated to Third Military Medical University, The Affiliated Hospital of Qingdao University, The First Affiliated Hospital of Chongqing Medical University and Yantai Yuhuangding Hospital, and Shanghai Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine was the group leader) were prospectively collected and retrospectively analyzed. There were 24 males and 82 females with an average age of 67.6±7.3 years, (range 45-80 years); Average body mass index 26.42±4.31 kg/m 2, all the operation were performed by "Skywalker" surgical robot system according to preoperative design based on CT. The operation time, intraoperative blood loss, hospitalization days and postoperative complications were recorded, and the imaging indexes including hip-knee-ankle (HKA), lateral distal angle of femur (LDFA) and medial proximal angle of tibia (MPTA) measured before and after the operation, implant model indexes (preoperative planning implant model and postoperative implant model) and short-term clinical efficacy indexes [Western Ontario and McMaster Universities (WOMAC) osteoarthritis index] pain score, stiffness score, joint function score, total score and SF-12 score before and 3 months after the operation) were compared. Results:The average follow-up period was 109.60±9.80 d, (range 95-143 d). The average operation time of 106 patients was 105.30±23.22 min; The average intraoperative blood loss was 141.70±58.33 ml; The average length of hospitalization was 5.82±2.80 d. One patient had ischemic stroke after operation, and one patient had abnormal liver function after operation. According to the judgment of the investigator, all of them were not related to the operation. The actual angle error is the difference between the preoperative planning angle and the postoperative measurement angle. The absolute error of 99.1% (105/106) of the HKA angle was within 3°, 90.8% (69/76) of LDFA, 98.7% (75/76) of the MPTA. In 45 patients in one center where data were available, the actual implant models used in all patients were consistent with the preoperative planning size, and there were only differences in version selection such as Asian condyle. WOMAC pain score, joint function score, total score was improved from 7.34±2.85, 25.10±9.85, 34.75±13.02 to 3.34±2.66, 14.68±9.64, 18.66±13.49 before and after operation, respectively, which were statistically significant ( P<0.001) and SF-12 physiological score and psychological score were improved form 27.24±6.42, 30.68±8.26 to 38.83±5.74, 39.36±7.85 before and after operation, respectively, which were statistically significant ( t=7.33, P<0.001; t=4.53, P=0.043). Conclusion:Domestic surgical robot system "Skywalker" can assist the surgeon to achieve accurate and personalized reconstruction of lower limb alignment and achieve satisfactory short-term clinical outcomes. The long-term clinical outcomes of personalized reconstruction and survival rate of implant still need to be further studied.

ABSTRACT

Objective:To investigate the feasibility and clinical efficacy of percutaneous anterior column screwing assisted by blocking screws for pelvic and acetabular fractures.Methods:A retrospective analysis was conducted of the 13 patients who had been admitted from July 2019 to April 2022 for pelvic and acetabular fractures. There were 8 males and 5 females with an age of (49.1±13.3) years, 7 acetabular fractures (6 on one side and 1 on both sides; by the Letournel-Judet classification: 5 anterior column fractures on 6 sides, and 2 transverse and posterior wall fractures on 2 sides), and 6 pelvic fractures (5 complicated with pelvic posterior ring fracture; by the Tile classification: 1 case of type B2, 3 cases of type C1, and 2 cases of type C2). According to the anatomic zones of the anterior column, 5 fractures were at zone Ⅲ, 3 ones at zone Ⅳ, and 6 ones at zone Ⅴ. The time from injury to surgery ranged from 3 to 14 days, averaging (8.2±2.9) days. Anterograde anterior column screwing assisted by blocking screws was performed for all the 13 patients; the posterior ring was fixated with percutaneous sacroiliac joint screws for the 5 patients complicated with pelvic posterior ring fracture. The surgical time, intraoperative fluoroscopy frequency, and intraoperative bleeding volume for insertion of anterior column screws, fracture reduction quality, and hip joint function at the last follow-up were recorded.Results:A total of 14 anterior column screws were inserted percutaneously in the 13 patients. For insertion of anterior column screws, the surgical time was (65.0±10.2) min, the intraoperative fluoroscopy frequency (63.5±14.5) times, and the intraoperative bleeding volume for each screw less than 30 mL. All the incisions healed primarily after surgery, without such complications as iatrogenic neurovascular injury or poor wound healing. All the 13 patients were followed up for (11.1±2.2) months after surgery. In the patient with bilateral acetabular anterior column fractures for which 2 anterior column screws had been inserted, one screw had to be removed due to its displacement at 1 month after surgery; no such complications as loosening of internal fixation or fracture re-displacement was found in the other patients. All fractures healed after (10.2±2.1) months. According to the Matta scoring for quality of fracture reduction, 7 sides were excellent, 5 sides good, and 2 sides poor; according to the Majeed scoring for the 6 patients with pelvic fracture at the last follow-up, the efficacy was rated as excellent in 4 cases and as good in 2 ones; according to the modified Merle d'Aubigné & Postel scoring for the 7 patients with 8 acetabular fractures at the last follow-up, the efficacy was rated as excellent in 4 hips, as good in 3 hips, and as fair in 1 hip.Conclusion:For pelvic and acetabular fractures, minimally invasive percutaneous anterior column screwing assisted by blocking screws can result in fine clinical efficacy, in addition to its easy procedures, safety and reliability.

ABSTRACT

Bone defects caused by different causes such as trauma, severe bone infection and other factors are common in clinic and difficult to treat. Usually, bone substitutes are required for repair. Current bone grafting materials used clinically include autologous bones, allogeneic bones, xenografts, and synthetic materials, etc. Other than autologous bones, the major hurdles of rest bone grafts have various degrees of poor biological activity and lack of active ingredients to provide osteogenic impetus. Bone marrow contains various components such as stem cells and bioactive factors, which are contributive to osteogenesis. In response, the technique of bone marrow enrichment, based on the efficient utilization of components within bone marrow, has been risen, aiming to extract osteogenic cells and factors from bone marrow of patients and incorporate them into 3D scaffolds for fabricating bone grafts with high osteoinductivity. However, the scientific guidance and application specification are lacked with regard to the clinical scope, approach, safety and effectiveness. In this context, under the organization of Chinese Orthopedic Association, the Expert consensus for the clinical application of autologous bone marrow enrichment technique for bone repair ( version 2023) is formulated based on the evidence-based medicine. The consensus covers the topics of the characteristics, range of application, safety and application notes of the technique of autologous bone marrow enrichment and proposes corresponding recommendations, hoping to provide better guidance for clinical practice of the technique.

ABSTRACT

Objective:To analyze the relationship between dietary composition of residents in endemic fluorosis areas and skeletal fluorosis.Methods:A case-control study was used to analyze the difference of dietary composition between patients with skeletal fluorosis (case group) and residents without skeletal fluorosis (control group). In August 2019, taking the drinking water-borne endemic fluorosis area in Wenshui County, Lvliang City, Shanxi Province as the survey site, a cluster sampling method was adopted to select local residents aged over 18 years old, and a questionnaire survey was conducted by face-to-face interview. The survey contents included gender, age and consumption frequency of various foods. Binary logistic regression was used to analyze the relationship between food consumption frequency and skeletal fluorosis. The diagnosis of skeletal fluorosis was made by using portable digital radiography (DR) to take X-ray films of forearm and lower leg, combining with clinical signs, and according to the Diagnostic Standard for Endemic Skeletal Fluorosis (WS/T 192-2008) to determine.Results:A total of 1 061 subjects were included in this study, including 376 in the case group and 685 in the control group. The age composition of patients in the case group (≤60, > 60 years old: 162, 214 cases) was significantly different from that in the control group (≤60, > 60 years old: 423, 261 cases, χ 2 = 34.52, P < 0.001). There was no statistically significant difference in gender ratio (χ 2 = 1.37, P = 0.251). The proportion of patients in the case group who ate meat and eggs > 1 time/week was lower than that in the control group (χ 2 = 8.06, 5.46, P < 0.05), the proportion of patients who ate milk > 1 time/week was higher than that in the control group (χ 2 = 4.01, P = 0.046), and the proportion of patients who ate seafood ≥1 time/week was lower than that in the control group (χ 2 = 4.16, P = 0.046). The results of binary logistic regression analysis showed that after adjusting for age, sex, and urinary fluoride, the frequency of eating meat, eggs or milk > 1 time/week and the frequency of eating seafood ≥1 time/week were not related to the risk of skeletal fluorosis ( P > 0.05); however, in the group ≤60 years old, the frequency of eating eggs > 1 time/week was associated with the risk of skeletal fluorosis [odds ratio ( OR) = 0.59, 95% confidence interval ( CI): 0.39, 0.88]. Conclusions:The consumption frequency of meat, milk, eggs and seafood is significantly different between the skeletal fluorosis patients and the control people. In the population ≤60 years old, consumption frequency of eggs > 1 time/week may reduce the risk of skeletal fluorosis.

ABSTRACT

Immunotherapy has become a common means of cancer treatment. In immunotherapy, PD-1/PD-L1 inhibitors have significant efficacy. Cancer and various opportunistic infections are common complications in patients with AIDS. Owing to the special immune situation of these patients, AIDS is regarded as an exclusion standard in most clinical trials for cancer immunotherapy, conferring immunotherapy difficulty in treating patients with AIDS. The popularity of effective antiretroviral drugs has prolonged the lifetime of people with AIDS. Therefore, exploiting the opportunity of using immunotherapy in AIDS with cancer is urgent.

ABSTRACT

OBJECTIVE@#To compare the clinical efficacy between herbal-moxa plaster and moxa-box moxibustion for diarrhea type irritable bowel syndrome (IBS-D) of spleen and kidney yang deficiency.@*METHODS@#Eighty patients with IBS-D of spleen and kidney yang deficiency were randomly divided into a herbal-moxa plaster group and a moxa-box moxibustion group, 40 cases in each group. The patients in the two groups were treated with conventional acupuncture at Baihui (GV 20), Yintang (GV 24+), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Yinlingquan (SP 9), and Taixi (KI 3), etc. In addition, the patients in the herbal-moxa plaster group were treated with herbal-moxa plaster (Wenyang Fuzheng ointment, composed of prepared monkshood, prepared evodia rutaecarpa, dried ginger, cinnamon, etc.) at Shenque (CV 8), Guanyuan (CV 4), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Shenshu (BL 23) and Shangjuxu (ST 37); the patients in the moxa-box moxibustion group were treated with moxa-box moxibustion at the same acupoints as the herbal-moxa plaster group. The acupuncture-moxibustion treatment was provided once every other day for 4 weeks (14 treatments). Before and after treatment, the scores of clinical symptom of TCM, irritable bowel syndrome (IBS) symptom severity scale (IBS-SSS) and IBS quality of life scale (IBS-QOL) were compared between the two groups, and the clinical efficacy was evaluated.@*RESULTS@#Compared with those before treatment, each item scores and total scores of clinical symptom of TCM, and IBS-SSS scores in the two groups were reduced after treatment (P<0.05). The abdominal bloating score, stool frequency score and total score of clinical symptom of TCM as well as IBS-SSS score in the herbal-moxa plaster group were lower than those in the moxa-box moxibustion group (P<0.05). Compared with those before treatment, the IBS-QOL scores in the two groups were increased after treatment (P<0.05), and the IBS-QOL score in the herbal-moxa plaster group was higher than that in the moxa-box moxibustion group (P<0.05). The total effective rate was 92.5% (37/40) in the herbal-moxa plaster group, which was higher than 85.0% (34/40) in the moxa-box moxibustion group (P<0.05).@*CONCLUSION@#On the basis of conventional acupuncture treatment, herbal-moxa plaster could effectively improve the clinical symptoms and quality of life in IBS-D patients of spleen and kidney yang deficiency, and its efficacy is superior to that of moxa-box moxibustion.

ABSTRACT

ObjectiveProteomics was used to investigate the protein differences between porcine cardiac blood(PCB) and porcine blood(PB) from Menghe medical school and to compare the effects of both on the microglial inflammation of Salviae Miltiorrhizae Radix et Rhizoma(DS). MethodNanoliquid chromatography-quadrupole orbitrap mass spectrometry(nLC-MS/MS) and bioinformatics were utilized to compare the proteomic differences of PCB and PB in simulated gastrointestinal digestion. Furthermore, Western blot was used to verify the contents of some shared proteins and differential proteins identified in PCB and PB. In addition, BV2 neuroinflammation model constructed by corticosterone(CORT) and lipopolysaccharide(LPS) was applied to detect the intervention effects of PCB and PB on the levels of tumor necrosis factor(TNF)-α and interleukin(IL)-6 in BV2 inflammatory cells of DS. ResultA total of 69 common proteins and 68 differential proteins were identified in PCB and PB, among which the common proteins included transferrin(Tf) with brain-targeting effect, and the differential proteins in the two were 41 and 27, respectively. Western blot validation showed that the difference in the content of the same protein Tf between PCB and PB was not statistically significant, while the difference in the contents of the specific proteins of creatine kinase M and heart-type fatty acid binding protein(H-FABP) were statistically significant(P<0.05). Moreover, in vitro experimental studies revealed that compared with the same concentration of DS group, in addition to the 100 mg·L-1 PB-DS group, PCB-DS and PB-DS groups could significantly inhibit the levels of TNF-α and IL-6 in BV2 inflammatory cells(P<0.05, P<0.01), and PCB-DS group had more significant anti-inflammatory effect than PB-DS group with the same concentration(P<0.05, P<0.01). ConclusionBoth of PCB and PB can enhance the inhibitory effect of DS on the release of inflammatory factors, thus playing a neuroprotective role, and PCB promotes DS inhibition more significantly, which may be due to the existence of the two involved in energy metabolism-related differential proteins, which can lay a foundation for revealing the scientific connotation of the processing of PCB-DS and PB-DS.

ABSTRACT

@#Abstract: Objective To explore the correlation between lung function in patients with chronic obstructive pulmonary disease (COPD) and tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) levels in exhaled breath condensate (EBC), and to provide a convenient methodological basis for the diagnosis and treatment of COPD and the determination of its efficacy. Methods A total of 81 COPD patients and 40 healthy controls were selected from the respiratory department of the Fourth Affiliated Hospital of Guangzhou Medical University from August 2020 to February 2022 as the research subjects. The COPD patients were divided into 41 cases in the acute exacerbation group and 40 cases in the remission group according to their status. All participants underwent lung function detection, venous blood and EBC collection, and the levels of TNF-α and IL-1β in EBC and venous blood were analyzed by enzyme-linked immunosorbent assay (ELISA), and correlation analysis was performed by Pearson correlation analysis method. Results The levels of TNF-α and IL-1β in EBC of in the acute exacerbation group, the healthy control group, the remission group were (5.16±0.18) pg/μL and (7.75±0.27) pg/μL, (2.66±0.31) pg/μL and (2.41±0.24) pg/μL, (3.61±0.29) pg/μL and (3.17±0.38) pg/μL, respectively. Compared with the healthy control group, the levels of TNF-α and IL-1β in EBC in the COPD acute exacerbation group were significantly higher than those in the healthy control group and the COPD remission group (F=9.451, 8.217, P<0.001). Serum tests were consistent with this result. Correlation analysis showed that the levels of TNF-α and IL-1β in EBC were significantly positively correlated with the level of serum inflammation levels (P<0.001), while significantly negatively correlated with lung function (P<0.001).  Conclusions TNF-α and IL-1β in EBC are potential biomarkers of inflammation in patients with COPD, and their detection can be used to effectively assess lung function in patients with COPD.

Methods    The literature on the safety and feasibility of early mobilization in critically ill patients with femoral catheters included in PubMed, EMbase, OVID, Springer-link, Wiley Online Library, and Web of Science up to June 2021 was searched, and relevant data were extracted for analysis. Results    Seventy-two papers were initially screened, and 12 papers that met the criteria were finally included, covering 1 056 patients, and 489 patients had femoral catheters. Patients underwent 6 495 sessions of physical therapy, and a total of 62 patients had adverse events, including 14 (2.86%, 14/489) patients with catheter-related adverse events. Conclusion    Although early mobilization in critically ill patients with femoral catheters may lead to adverse catheter-related events, the incidence is low. Therefore, the associated risks and benefits should be weighed in clinical practice, and femoral catheter is not recommended as a contraindication for early mobilization in critically ill patients.

ABSTRACT

Atherosclerosis is the main cause of cardiovascular diseases, while Carotid intima-media thickness is a biomarker of subclinical atherosclerosis. Numerous studies have confirmed that exercise can slow down or even reverse the formation and progression of carotid Intima-Media thickness. This paper provides a review of the effects of different exercise modalities, intensities, and populations on the vascular structure to provide a reference for the prevention of atherosclerosis with exercise.

ABSTRACT

At the early stage of tooth development, the tooth embryo underwent three successive stages: bud stage, cap stage and bell stage through the interaction between epithelium and mesenchymal cells. During these stages, especially during the interphase transition, the presence of signal centers was particularly crucial. Signal center was composed of a small group of oral epithelial cell collections which were formed in a specific sequence, playing a decisive role in signal expression, morphogenesis and cell differentiation by secreting growth factors and other signaling molecules to regulate developmental signaling pathways. This paper reviews the evolution of signal centers as well as the important signal molecules and transcription factors in signal centers since the formation of dental placode.

ABSTRACT

Objective: To examine the clinical value of fluorescence-guided indocyanine green (ICG) laparoscopic anatomical hepatectomy in the treatment of primary hepatocellular carcinoma. Methods: Data from patients diagnosed with hepatocellular carcinoma and who underwent laparoscopic hepatectomy with ICG fluorescence navigation in the Department of Liver Surgery and Liver Transplantation Center of West China Hospital between September 2020 and May 2022 were retrospectively collected. There were 53 males and 19 females, with an age of (55.5±12.9)years(range:42.6 to 68.4 years). Among them, 13 of the cases underwent laparoscopic anatomical liver resection(LALR) guided by tans-arterial ICG,43 of the cases received LAIR guided by portal vein negative ICG, and 16 of the cases received LALR positive by portal vein. Comparison among the three groups was performed by one-way ANOVA; and the rank sum test was used for comparison between groups. The counting data was expressed as percentage,and the χ2 test or Fisher's exact probability method was used for comparison between groups. Results: (1) Postoperative pathology: Resection R0 was achieved in all operations. The maximum tumor diameter of the patients in the arterial staining group, the reverse staining group, and the positive staining group(M (IQR)) was 2.5 (2.4) cm, 3.0 (2.5) cm and 3.0(2.4) cm,respectively. There were no statistically significant differences in the maximum tumor diameter between the three groups (P=0.364). The minimum tumor margin was 1.1 (1.1) cm, 1.0 (1.0) cm, 1.1 (1.6) cm in the the arterial staining group, reverse staining group and the positive staining group, respectively. There was no significant difference in the margin among the three groups (P=0.878). (2) Operation conditions: the operation time of the arterial staining group, the negative staining group, and the positive portal staining group was (348±93)minutes,(277±112)minutes,and (295±116)minutes,respectively. There were no significant differences in operation time among the three groups (P=0.134). The intraoperative blood loss of the three groups was 80(150)ml,200(350)ml,and 100(150)ml,respectively. There was no statistically significant difference in intraoperative bleeding volume between the three groups(P=0.743). All cases were not transfused during the operation and were not converted to laparotomy. ALT in the arterial staining group was higher than in the negative staining group in the first two days after the operation ((559±398)IU/L307(257) IU/L, q=235.5,P=0.004;(611±389)IU/L(331±242) IU/L, q=265.2, P=0.002). There was only one case of a grade III complication (Clavien-Dindo grading system) postoperative complication in the negative and positive staining group of the portal vein, respectively. Tumor markers in all patients decreased to the normal range after 2 months of operation. Conclusion: Laparoscopic anatomical hepatectomy guided by ICG fluorescence through arterial staining and portal vein staining is safe and feasible for primary hepatocellular carcinoma treatment.

ABSTRACT

Objective:To explore the impact of PM 2.5 concentration in Shanghai on the incidence of allergic rhinitis(AR) in the population, and provide strategies for early warning and prevention of AR. Methods:Collect daily average concentrations of atmospheric pollutants monitored in Shanghai from January 1, 2017 to December 31, 2019, and clinical data of AR patients from five hospitals in Shanghai during the same period. We used a time-series analysis additive Poisson regression model to analyze the correlation between PM 2.5 levels and outpatient attendance for AR patients. Results:During the study period, a total of 56 500 AR patients were included, and the daily average concentration of PM 2.5 was(35.28±23.07)μg/m³. There is a correlation between the concentration of PM 2.5 and the number of outpatient attendance for AR cases. There is a positive correlation between the daily average number of outpatient for AR and levels of PM 2.5 air pollution((P<0.05)) . We found that every 10 μg/m³ increase in PM 2.5, the impact of on the number of AR visits was statistically significant on the same day, the first day behind, and the second day behind, with the strongest impact being the exposure on the same day. Every 10 μg/m³ increases in PM 2.5, the number of outpatient visits increased by 0.526% on the same day(95%CI 1.000 50-1.010 04). Conclusion:The atmospheric PM 2.5 concentration in Shanghai is positively correlated with the number of outpatient for AR, and PM 2.5 exposure is an independent factor in the onset of AR. This provides an important theoretical basis for AR.
