In recent years， the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine， the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances， TCM theories of etiology and pathogenesis， the role and advantages of TCM in the whole course management of pulmonary nodules， contents and methods of research on pulmonary nodules， and science popularization work， aiming to provide a reference for clinical practice and scientific research. After discussion， the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness， blood stasis， and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules， improving physical constitution， ameliorating multi-system nodular diseases， reducing anxiety and avoiding excessive diagnosis and treatment， and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present， the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed， which needs to be further studied from multiple perspectives such as clinical epidemiology， biology， and evidence-based medicine. The primary task of current research is to find out the advantages， effective prescriptions， and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time， basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized， scientific， and accurate effective diagnosis and treatment.

Promoting health knowledge and improving the public's health literacy is an inherent requirement of the Healthy China Initiative.In the era of deepening implementation of the Healthy China strategy and rapid development of all media,large public hospitals play an irreplaceable and important role in leading the popularization of health knowledge and impro-ving the quality of information.However,in the process of carrying out health popularization work,many hospitals still face prob-lems such as lack of a regular working mechanism,lack of comprehensive team building,and lack of differentiated operation strategies.In response to these problems,the First Affiliated Hospital of Sun Yat-sen University has established a health populari-zation working mechanism led by the Party organization and coordinated at all levels,and has innovated in terms of personnel team,platform construction,content creation,and expression form,exploring a new model of health popularization work to pro-vide reference for other hospitals.

Objective:To evaluate the impact of orthopedic robotic assistance and conventional freehand methods on surgical strategies, the safety of pedicle screw placement, and clinical efficacy in patients with upper cervical spine diseases.Methods:From January 2017 to March 2023, a total of 63 cases with upper cervical spine disease, were divided into two groups based on the screw placement technique: the robot-assisted pedicle screw placement (RA) group (41 cases) and the conventional freehand pedicle screw placement (CF) group (22 cases), were retrospectively included. These patients in the RA and CF groups underwent two types of posterior cervical surgery, including occipitocervical fusion (9 cases and 8 cases) and fixation and fusion of atlantoaxial and distal vertebrae (32 cases and 14 cases). The outcome parameters, including the disease course, surgical time, intraoperative blood loss, fluoroscopy frequency, radiation dose, hospital stay, treatment costs, complications, the rate of the pedicle screw placement, accuracy of upper cervical pedicle screw placement, and the risk factors that possibly affected the accuracy were recorded and analyzed. Postoperative follow-up was conducted for at least 6 months, and the efficacy of patients was assessed using imaging parameters, ASIS classification, VAS, and JOA scores.Results:Both groups had no screw-related complications and no spinal cord or vertebral artery injuries. In the RA group, the pedicle screw placement rates for the patients with occipitocervical fusion, and fixation and fusion of atlantoaxial and distal vertebrae were 100% (48/48) and 89.6% (138/154), respectively, far exceeding the placement rate in the CF group 42.9% (18/42) and 78.3% (54/69) (χ 2=37.403, P<0.001; χ 2=5.128, P=0.024). The fluoroscopic exposure dose and operation time of the two types of surgical patients in the RA group were both higher than those in the CF group ( P<0.05). Compared with the CF group, the accuracy of C 1 screws in the RA group increased from 42% (11/26) to 80% (51/64), with statistical significance (χ 2=13.342, P=0.004); while the accuracy of C 2 screws improved from 77% (33/43) to 88% (63/72) with no statistical difference (χ 2=2.863, P=0.413). Non-parametric correlation analysis found a significant correlation between the accuracy of C 1 and C 2 pedicle screw placement and the order of guide wire insertion in the RA group ( r=0.580, P<0.001; r=0.369, P=0.001). Postoperatively, both groups showed significant differences in cervicomedullary angle (CMA), Chamberlain angle (CL), McGregor angle, Boogard angle, Bull angle, clivus-canal angle (CCA), occipitocervical (C 0-C 2) angle, posterior occipitocervical angle (POCA), C 2-C 7 angle, and anterior atlantodental interval (ADI) ( P<0.05). The ASIA classification improved to varying degrees for both groups postoperatively, but there were no statistically significant differences between preoperative, postoperative, and last follow-up evaluations. VAS and JOA scores significantly improved for both groups postoperatively and at the last follow-up ( P<0.05). Conclusion:Both orthopedic robotic-assisted and conventional freehand pedicle screw placement techniques achieved satisfactory therapeutic effects in the treatment of upper cervical spine diseases. The orthopedic robot can effectively ensure the accuracy of upper cervical pedicle screw placement, the increase placement rate of pedicle screws in the upper cervical spine, and reduce fluoroscopy exposure. However, it is necessary to avoid the vertebral displacement caused by the priority insertion of the guide needle, which may affect the accuracy of subsequent planning.

Objective To investigate the improvement effect and mechanism of Modified Kongsheng Zhenzhong Dan medicated serum on mitochondrial function of PC12 cells injured by oxygen-glucose deprivation/reperfusion(OGD/R)based on the SIRT1/PGC-1α pathway.Methods PC12 cells were used to construct OGD/R cell model in vitro.Cell grouping:normal group(10%FBS),model group(10%FBS),10%drug-containing serum group,5%drug-containing serum group(5%drug-containing serum+5%blank serum),10%blank serum group(control group).CCK-8 method was used to detect the cell survival rate,and the appropriate oxygen glucose deprivation time(2,4,6,8 hours)was screened.MTT assay was used to detect cell activity;mitochondrial stress test(MST)was used to detect the oxygen consumption rate(OCR).Apoptosis was detected by flow cytometry(Annexin V-PE/7-AAD double staining).The protein expression levels of SIRT1 and PGC-1α in PC12 cells were detected by Western Blot.Results Compared with the normal group,the activity of PC12 cells decreased significantly after oxygen-glucose deprivation for 2,4,6 and 8 hours(P＜0.05),and 6 hours of oxygen-glucose deprivation was selected as the time of subsequent experimental modeling.Compared with the normal group,the cell activity of the model group was significantly decreased(P＜0.05).The OCR values of basic respiration value,maximum respiration value,proton leakage,ATP production and standby respiration ability were significantly decreased(P＜0.05).The apoptosis rate was significantly increased(P＜0.05).The protein expression levels of SIRT1 and PGC-1α in cells were significantly decreased(P＜0.05).Compared with the model group,the cell activity of the Modified Kongsheng Zhenzhong Dan 10%and 5%drug-containing serum groups was significantly increased(P＜0.05).The OCR values of basal respiration value,maximum respiration value,proton leakage,ATP production and spare breathing ability were significantly increased(P＜0.05).The apoptosis rate was significantly decreased(P＜0.05).The protein expression levels of SIRT1 and PGC-1α in cells were significantly increased(P＜0.05).Conclusion The Modified Kongsheng Zhenzhong Dan medicated serum can improve mitochondrial dysfunction,inhibit neuronal apoptosis and promote neuronal survival in OGD/R-injured PC12 cells.The mechanism may be related to the activation of SIRT1/PGC-1α signaling pathway.

Objective:To evaluate the quality of life (QoL) of Chinese chronic pancreatitis (CP) patients based on the Chinese version of the pancreatitis quality of life Instrument (PANQOLI) and explore its impact factors.Methods:404 patients with CP admitted to the Department of Gastroenterology of the First Affiliated Hospital of Naval Medical University between September 2021 and January 2022 were enrolled. The Chinese version of PANQOLI was used for questionnaire survey on QoL of CP patients. Univariate analysis and multiple linear regression analysis were used to explore the impact factors for QoL of CP patients.Results:The total score of QoL of 404 Chinese CP patients was 28-94(72.47±13.61), which declined by 29.64% compared to the highest total score (103) in the Chinese version of PANQOLI. Score of physical function, role function, emotional function, and self-worth domain was 25.63±4.84, 13.86±2.78, 16.98±6.21 and 16.00±4.65, respectively. Compared to the highest scores (30, 25, 24 and 24), the scores of aforementioned four domains declined by 14.57%, 44.56%, 29.25% and 33.33%, respectively. Univariate analysis showed that sex, age, employment status, smoking, alcohol consumption, and frequency of pancreatitis recurrence were significantly associated with QoL of CP patients. Multiple linear regression analysis indicated that older age (coefficient=-0.127), unemployment status (coefficient=-0.106), smoking (coefficient=-0.176), and high frequency of pancreatitis recurrence (coefficient=-0.123) were independent factors for QoL of CP patients (all P value <0.05). Conclusions:The Chinese version of PANQOLI could be effectively applied to Chinese CP patients. Older age, unemployment, smoking, and pancreatitis attacks were risk factors for QoL of CP patients, indicating that the formulation of personalized intervention measures may help to improve QoL of CP patients.

Glycyrrhizae Radix et Rhizoma,a traditional Chinese medicine also known as Gan Cao(GC),is frequently included in clinical prescriptions for the treatment of pneumonia.However,the pharmacological com-ponents of GC for pneumonia treatment are rarely explored.Gan An He Ji oral liquid(GAHJ)has a simple composition and contains GC liquid extracts and paregoric,and has been used clinically for many years.Therefore,GAHJ was selected as a compound preparation for the study of GC in the treatment of pneumonia.We conducted an in vivo study of patients with pneumonia undergoing GAHJ treatments for three days.Using the intelligent mass spectrometry data-processing technologies to analyze the meta-bolism of GC in vivo,we obtained 168 related components of GC in humans,consisting of 24 prototype components and 144 metabolites,with 135 compounds screened in plasma and 82 in urine.After analysis of the metabolic transformation relationship and relative exposure,six components(liquiritin,liquiritigenin,glycyrrhizin,glycyrrhetinic acid,daidzin,and formononetin)were selected as potential effective components.The experimental results based on two animal pneumonia models and the in-flammatory cell model showed that the mixture of these six components was effective in the treatment of pneumonia and lung injury and could effectively downregulate the level of inducible nitric oxide synthase(iNOS).Interestingly,glycyrrhetinic acid exhibited the strongest inhibition on iNOS and the highest exposure in vivo.The following molecular dynamic simulations indicated a strong bond between glycyrrhetinic acid and iNOS.Thus,the current study provides a pharmaceutical basis for GC and reveals the possible corresponding mechanisms in pneumonia treatment.

Objective:To explore the etiology, pathogenesis, clinical features, diagnosis and treatment of hepatic sinus obstruction syndrome(HSOS)after orthotopic liver transplantation(OLT).Methods:Clinical data were reviewed for 3 HSOS patients after OLT.Baseline profiles, primary disease, onset, clinical manifestations, abdominal imaging and pathological changes were recorded for summarizing the key points of diagnosis, treatment and outcomes of HSOS after OLT.Results:HSOS was an extremely rare complication after OLT with an incidence of 2%(2/117)and a median onset of 15(13-50)days.The major clinical manifestations were hepatic pain, abdominal distension, poor appetite, fatigue, jaundice, oliguria, peritoneal effusion and pleural effusion.Some of them were complicated with acute renal insufficiency.Abdominal ultrasonography revealed that blood stream of hepatic and portal veins was smooth but rather slow and hepatic parenchyma showed uneven echo changes.Abdominal enhanced computed tomography(CT)demonstrated " mosaic" and " map-like" uneven enhancement in portal vein and balance phases.The pathological manifestations of liver biopsy included obvious dilation and congestion of hepatic sinuses, swelling and necrosis of hepatic cells, thickening of hepatic venules and luminal stenosis or occlusion.All of them received immunosuppressants.Tacrolimus was switched to sirolimus, low molecular weight heparin or plus rivaroxaban anticoagulant thrombolytic therapy, methylprednisolone regulatory immunotherapy, albumin supplementation, diuresis, hepatic protection and fluid replacement.Afterward clinical symptoms of 2 patients improved, became cured and discharged.One case died from gastrointestinal hemorrhage and acute renal failure secondary to multiple organ failure.Conclusions:HSOS is an extremely rare but severe complication after OLT.Early diagnosis and fine-tuning of treatment protocols can avoid poor prognosis such as liver and kidney failure and significantly improve patient survival.

Therefore, starting from the pathological changes of radiation enteritis, this article reviews the mechanism of the acute and chronic radiation enteritis, hoping to provide clinical reference.

Objective:To compare the clinical characteristics, clinical efficacy and adverse drug reactions of rheumatoid factor (RF) positive (+ ) and negative (-) polyarticular juvenile idiopathic arthritis (PJIA).Methods:The clinical data of 67 PJIA patients admitted into Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, from January 2013 to December 2018 were analyzed retrospectively.They were divided into RF-positive PJIA group [RF (+ ) group, 23 cases] and RF-negative PJIA group [RF (-) group, 44 cases] according to RF titer.The clinical characteristics, laboratory indexes and clinical efficacy evaluation of the two groups were compared.Results:(1)Distribution of affected joints: the top 3 affected joints in the RF (+ ) group were the knuckles (16 cases, 69.57%), the wrists (15 cases, 65.22%) and the ankles (13 cases, 56.52%), and those in the RF (-) group were the knees (33 cases, 75.00%), ankle joints (29 cases, 65.91%) and hip joints (26 cases, 59.09%). The wrist joint involvement of the RF (+ ) group was significantly higher than that of the RF (-) group, while the knee joint involvement was lower than that of the RF (-) group.The difference was statistically significant (all P<0.01). (2)Magnetic resonance changes of the affected joints: articular cavity effusion (54 cases, 84.38%), synovial thickening (44 cases, 68.75%) and bone edema (26 cases, 40.63%) are common in both groups.The incidence of bone destruction (7 cases, 70.00%) and soft tissue edema (7 cases, 70.00%) in the RF (+ ) group was higher than that in the RF (-) group (2 cases, 18.18% and 2 cases, 18.18%), the difference was statistically significant (all P<0.05). (3) Changes in laboratory indicators: the positive rates of C-reactive protein, erythrocyte sedimentation rate, anti-cyclic citrullinated peptide antibody and anti-nuclear antibody in the RF(+ ) group were significantly higher than those in the RF(-) group, the difference was statistically significant (all P<0.05). (4)Juvenile arthritis disease activity score 27 (JADAS27): the score difference between RF(+ ) group and RF(-) group was not statistically significant [(22.83±5.60) scores vs.(23.07±6.66) scores, t=0.148, P>0.05]. (5) Efficacy analysis: 2 patients were lost to follow-up after discharge, and the remaining 65 patients were treated with traditional therapy, of which 30 were given biologics at the first hospitalization, 9 cases were treated with biologics after the failure of traditional treatments, and 35 patients were treated with biologics to control disease activity.In different dosage regimens, the disease remission rate in the RF(-) group is generally higher than that in the RF(+ ) group. Conclusions:PJIA patients have complicated joint involvement, RF-positive patients are more prone to joint destruction, and traditional treatments are less effective.Biological agents can effectively improve the symptoms of severe PJIA patients, especially those with poor prognosis.
