ObjectiveTo observe the clinical efficacy of Gandou Fumu Granules （GDFMG） combined with sodium dimercaptosulphonate （DMPS） on liver fibrosis in Wilson disease （WD） patients with the syndrome of phlegm and blood stasis， evaluate its effect on cuproptosis-related indicators， and explore the possible mechanisms of cuproptosis in WD-related liver fibrosis. MethodsSixty WD patients diagnosed with the syndrome of phlegm and blood stasis between January 2023 and December 2023 were randomly divided into a control group and an observation group， with 30 patients in each group. The control group received the copper chelator DMPS for the first 6 days， followed by calcium gluconate injection for the next 2 days， completing an 8-day treatment cycle. The observation group received GDFMG in addition to the treatment regimen of the control group， with both groups treated for 21 cycles. A Beckman fully automated biochemical analyzer was used to detect levels of type Ⅳ collagen （CⅣ）， hyaluronic acid （HA）， laminin （LN）， N-terminal propeptide of type Ⅲ procollagen （PⅢ-NP）， and serum copper （SCu） before and after treatment in both groups. Enzyme-linked immunosorbent assay （ELISA） was used to measure levels of ferredoxin 1 （FDX1）， lipoic acid synthetase （LIAS）， and dihydrolipoamide S-acetyltransferase （DLAT）. Atomic absorption spectroscopy measured 24-hour urine copper levels before treatment and after the 7， 14， and 21 treatment cycles in both groups. An Fibro Touch （FT） non-invasive liver fibrosis diagnostic device was used to measure liver stiffness （LSM） in both groups before and after treatment. Traditional Chinese medicine syndrome score （TCMSS） was evaluated at the same intervals. Clinical efficacy， adverse events， and safety indicators were also compared. ResultsAfter treatment， levels of CⅣ， HA， LN， and PⅢNP significantly decreased in both groups compared to pre-treatment levels （P<0.01）. The observation group showed a more pronounced reduction compared to the control group （P<0.05）. There were no statistically significant differences in SCu levels in both groups before and after treatment. After treatment， levels of FDX1，LIAS and DLAT significantly increased in both groups（P<0.01）. The observation group showed more notable improvements in these indicators than the control group （P<0.05）. After the 7， 14， 21 treatment cycles， 24-hour urine copper levels significantly increased in both groups compared to pre-treatment levels （P<0.01）. The observation group had a greater increase in 24-hour urine copper levels than the control group after treatment （P<0.05，P<0.01）， and although 24-hour urine copper levels increased after 7 cycles， a gradual decline was observed in subsequent cycles. After treatment， LSM levels significantly decreased in both groups compared to pre-treatment levels （P<0.01）， with the observation group showing a greater reduction than the control group （P<0.05）. Clinical efficacy was significantly better in the observation group than the control group （P<0.05）. No significant differences in the incidence of adverse events or safety indicators were observed between the two groups after treatment. ConclusionGDFMG combined with DMPS can reduce LSM in WD patients with liver fibrosis and the syndrome of phlegm and blood stasis， inhibit cuproptosis， and improve clinical efficacy.

Objective: To retrospectively analyze the epidemiological characteristics of supernumerary teeth in patients aged 4-18 years old and the influencing factors on the selection of anesthesia methods, and to provide a reference for the selection of anesthesia plans for children and adolescents with supernumerary teeth. Methods: This study is a retrospective study approved by the Institutional Ethics Committee. Based on clinical electronic medical record system and cone beam CT (CBCT) data, a retrospective analysis was conducted on 2 210 patients 4-18 years of age who underwent supernumerary tooth extraction at the School of Stomatology, Fourth Military Medical University from August 2019 to July 2021. Inclusion criteria: ① Age 4-18 years old; and ② The American Society of Anesthesiologists (ASA) classifies anesthesia into grades I-II; and ③ Have complete oral and anesthesia case records and relevant imaging data. Exclusion criteria: ① Incomplete medical records or unclear imaging data; and ② Patients with ASA grade II or above. Patients’ gender and age, the number of supernumerary teeth, arch, location, orientation, eruption status, reason for appointment, anxiety level, degree of cooperation, anesthesia method, and other relevant information were collected and statistically analyzed. Results: A total of 1 865 eligible patients were included, with an average age of (8.9±3.2) years old. There were more male patients (71.37%, 1 331 cases) than female patients (28.63%, 534 cases) (P < 0.001), with a gender ratio of 2.49:1. The majority of supernumerary teeth were single (75.97%, 1 417/1 865), primarily located in the maxilla (97.2%, 1 812/1 865) and the anterior dental region (94.2%, 1 757/1 865), and in a centric position (77.3%, 1 442/1 865). The majority of patients with erupted supernumerary teeth were active in seeking treatment (97.67%, 335/343). Patients with supernumerary teeth located in the maxilla and mandible bones, as well as in the nasal floor, were mainly referred to the department for diagnosis, accounting for 94.38%(1 361/1 442) and 90.00% (72/80) (χ2=1 363.24, P < 0.001), respectively. Regarding anesthesia methods, the largest proportion of patients received nitrous oxide sedation-assisted local anesthesia or nerve block anesthesia, accounting for 38.07% (710/1 865), followed by local anesthesia, accounting for 35.23% (657/1 865). The proportion of patients receiving midazolam intravenous sedation with local anesthesia or nerve block anesthesia and general anesthesia was relatively small, accounting for 20.86% (389/1 865) and 5.84% (109/1 865). Patients 13-18 years of age with supernumerary teeth in the mandibular and posterior regions and without anxiety had the highest proportion of local anesthesia use (P < 0.001). In contrast, patients who had supernumerary teeth located at the base of the nose (50%), severe anxiety (94.12%), and poor cooperation (98.18%) had the highest proportion of general anesthesia use (P < 0.001). There was no significant difference (P = 0.35) in the incidence of intraoperative and postoperative complications after the extraction of supernumerary teeth. However, the proportion of anesthesia-related complications, such as dizziness, coughing, and respiratory depression, occurring in patients who received general anesthesia was higher than local anesthesia, accounting for 3.81% (P = 0.006). Conclusion There is a gender difference in the incidence of supernumerary teeth in patients 4-18 years of age, with a higher prevalence in males. The majority of supernumerary teeth are single and located in the maxillary anterior region, predominantly in a centric position. Patients whose teeth had erupted were more likely to seek medical treatment voluntarily, while patients with supernumerary teeth located in the maxilla and mandible bones, as well as in the nasal floor were more likely to be referred to the department. Patients with high levels of anxiety, poor cooperation, young age, multiple teeth, and high surgical difficulty were more inclined to choose general anesthesia.

Establishing a comprehensive mechanism for the initiation and review of investigator-initiated trial(IIT) plays an important role in ensuring the scientific validity of clinical research and improving research quality.Since 2021, Zhongshan Hospital affiliated to Fudan University had actively explored improvements in the project management of IIT. The hospital had established a standardized grading review management process, developed an integrated clinical research management system, established a three-level clinical research training system, built a methodological support platform, and formulated research plan templates, gradually formed a standardized grading project approval review management mode. As of February 2024, the hospital had completed 400 quick reviews and more than 400 expert letter reviews based on the integrated clinical research management system. The efficiency and quality of IIT project approval had been improved.

Objective:Correct chest compression posture (CCP) is an important basis for high-quality cardiopulmonary resuscitation, but the research on CCP was still very limited. In this study, a new automatic analysis model was developed to achieve the purpose of objectification, standardization and automation of CCP monitoring.Methods:A total of 15 participants, including 11 professionals and 4 nonprofessionals, were recruited to participate in the field experiment. The video data were recorded simultaneously with zed cameras in the front and 45-degree sides. All participants performed 120 consecutive external chest compression operations on the Smartman CPR simulator. Three experts annotated the videos independently. An intelligent algorithm was used to extract human bone points for subsequent analysis and model development. The chi-square test was used to compare the rates of the professional and nonprofessional groups.Results:The results showed that problems with wrists, fingers, center of body weight and elbow bending had the highest incidence. Through 28 800 sets of standard human skeleton point coordinate data, we obtained a reasonable range of arm angles of 169.24°- 180.00° for the left arm and 168.49°-180.00° for the right arm. By the same method, the reasonable range of the center of gravity angle is 0.00°-18.46°. Based on these results, a new chest compression posture detection model based on a dual ZED camera was developed, which can accurately identify CCP errors (accuracy 91.31%; sensitivity 80.16%; specificity 93.53%).Conclusions:This study innovatively proposed an objective evaluation method for CCP. Moreover, a new chest compression posture detection model based on a dual ZED camera was developed, which can accurately identify CCP errors to achieve automation and standardization of quality control in CPR training.

Objective:To explore the effect of triglyceride glucose(TyG) index, single nucleotide polymorphism of Toll-like receptor 4(TLR4) and NOD-like receptor thermal protein domain associated protein 3(NLRP3) genes, and its interaction on the risk of gout.Methods:A total of 315 male patients with gout and 499 men for health checkup at the same period were selected. General data were collected through questionnaires, and peripheral venous blood was collected for biochemical test. Three single nucleotide polymorphisms(SNPs) of NLRP3 and TLR4 were detected with multiplex ligase assay reaction, and logistic regression analysis was applied to compare the correlation between NLRP3 and TLR4 alleles and gout risk. The interaction of SNP and TyG index with gout was analyzed by generalized multi-factor dimensionality reduction(GMDR) model and logistic regression.Results:After adjusting for smoking, drinking, and other factors, the risk of gout increased by 61.1% for each standard deviation increase in TyG index. CC genotypes of rs10754558, rs10759932, and rs7525979 were high risk genotypes of gout in Han ethnicity. GMDR results showed significant differences in the interaction models of rs10754558-TyG index, rs7525979-TyG index, and rs10759932-TyG index between control group and gout group( P<0.05), suggesting an interaction between the three genotypes of SNPs selected and TyG index. Stratified analysis of the three selected SNPs and TyG index showed that after adjusting for age, smoking, and other factors, the high TyG index patients carrying C/C or C/G genotype at rs10754558 displayed an increased risk of gout compared with those carrying GG genotype and low TyG index( OR=2.127, P<0.05). Conclusion:The CC genotypes of rs10754558, rs10759932, and rs7525979 are high risk genotypes for gout in Han ethnicity. The interaction between rs10754558 and TyG index may increase the risk of gout development.

Objective: To investigate the association between health literacy (HL) and health related quality of life (HRQoL) among primary and middle school students in Nanjing,and to provide a reference for improving health literacy and health related quality of life among children. Methods: In this cross sectional study, by using a multi stage rondom duster sampling method,a total of 4 388 primary (4-6), junior (grades 7-9) and senior (grades 10-12) high school students were randomly selected in Nanjing during May and June of 2018. HRQoL was measured as continuous variable with the validated Chinese version of Child Health Utility 9D (CHU9D CHN); the relationship between health literacy level and HRQoL was examined using mixed effect linear regression models and reported as mean difference ( MD ) and 95% confidence interval( CI ). Results: There were 85.8% participants who obtained adequate health literacy level, while the mean score of CHU9D CHN was (0.78±0.17) for overall participants. After control for potential confounding factors and class level clustering effects, participants who self reported adequate HL recorded an increased HRQoL scores of 0.08 (95% CI =0.06-0.10) units relative to those self reporting inadequate HL. According to the stratified analysis of students gender, school type and place of residence, the results show that after adjusting the relevant confounding factors and the aggregation of class level, compared with the students without health literacy, the score of health related quality of life of those with health literacy increased significantly. Conclusion Health literacy of primary school students in Nanjing is positively related to health related life qualities.Therefore,there is a need to promote student s health related quality of life through health literacy.

Objective To investigate the association between the osteogenic differentiation in the soft tissue lump and the clinicopathological characteristics of osteosarcoma patients. Methods We retrospectively reviewed the clinical data of conventional osteosarcoma patients with soft tissue lumps, including Enneking stages, chemotherapy sensitivity, overall survival and post-metastatic survival time. The ossification level in soft tissue lumps was assessed by imaging and the proportion of osteoid matrix was assessed by pathological examination. Results A total of 189 cases were included in this study. In patients with Enneking IIIB, non-osteoblastic, partially osteoblastic and osteoblastic types accounted for 30.2%, 9.6% and 6.3%, respectively. Non-osteoblastic osteosarcoma patients had a higher rate of initial metastasis (P < 0.05); Chemotherapy efficiency of non-osteoblastic, partially osteoblastic and osteoblastic types were 60.5%, 59.6% and 31.3%, respectively. The osteoblastic osteosarcoma held the worst rate of chemotherapy sensitivity (P < 0.05). The overall survival of non-osteoblastic osteosarcoma was shorter than those of partially osteoblastic and osteoblastic types (P < 0.05). Post-metastatic survival time of osteoblastic osteosarcoma was longer than that of non-osteoblastic osteosarcoma (P=0.078). Conclusion For conventional osteosarcoma, the osteogenesis level in soft tissue lumps is related to the surgical stage, chemotherapy sensitivity and prognosis of tumors, which may provide guidance for the individual decision regarding chemotherapy and surgery timing on patients.

Objective: To explore the association of physical activity and screen time with health-related quality of life among students in China. Methods: A total of 4 388 students (graders 4-12) were randomly selected from primary, junior and senior high schools in Nanjing, China, to take part in this cross-sectional questionnaire survey in 2018. The associations of physical activity and screen time with health-related quality of life were assessed using mixed-effects linear regression models and reported as mean difference (MD) and 95% confidence interval(CI). Results: After adjustment for potential confounders and class-level clustering effects, students with sufficient physical activity reported an increased 0.03 (95%CI=0.01-0.05) unit of the Child Health Utility 9D (CHU9D) scores compared to their counterparts with insufficient physical activity, while participants with short screen time also recorded higher CHU9D scores 0.05(95%CI=0.02-0.08) than those with prolonged screen time. Relative to those with insufficient physical activity and prolonged screen time, students with insufficient physical activity and short screen time 0.05(95%CI=0.02-0.09), or students with sufficient physical activity and prolonged screen time 0.03(95%CI=-0.03-0.10), or students with sufficient physical activity and short screen time 0.08(95%CI=0.05-0.12), respectively, reported increased CHU9D scores. Conclusion Health-related quality of life was positively associated with physical activity, but negatively with screen time. Moreover, these two factors may have a combined effect on health-related quality of life.

Objective To explore the value of pulse index continuous cardiac output (PICCO) combined with intracranial pressure monitoring in patients with severe craniocerebral injury.Methods One hundred and thirty-eight patients with severe craniocerebral injury accepted controlling decompression surgical treatment in our hospital from February 2015 to February 2019 were prospectively chosen.According to patients' families will,postoperative application of PICCO combined with intracranial pressure monitoring for fluid management was performed in 72 patients (treatment group) and application of central venous pressure combined with intracranial pressure monitoring for fluid management was performed in 66 patients (control group).All patients were adjusted according to the monitoring results.The intracranial pressure and cerebral perfusion pressure one week after surgery,incidences of new traumatic cerebral infarction,neurogenic pulmonary edema,pulmonary infection,scalp exudation,and intracranial infection,average hospitalization days,total hospitalization costs,intensity of antimicrobial use,and Glasgow coma scale scores two weeks after operation were compared and analyzed between the two groups.Glasgow outcome scale was used to evaluate the prognoses of the patients 6 months after injury.Results There were 7 patients (3 from the control group and 4 from the treatment group) dropped out of the study due to various reasons and 131 patients (63 from the control group and 68 from the treatment group) included in the final statistical analysis;there was no significant difference in drop-out rate of the two groups (P＞0.05).The intracranial pressure in the treatment group ([14.28±2.98] mmHg) was significantly lower than that in the control group ([18.99±2.78] mmHg) and cerebral perfision pressure ([66.72±2.25] mmHg) was significantly higher than that in the control group ([52.96±3.12] mmHg) one week after operation (P＜0.05).During hospitalization,the incidences of new traumatic cerebral infarction,neurogenic pulmonary edema,pulmonary infection,scalp exudation and intracranial infection in the treatment group (8.8％,13.2％,11.8％,7.4％,and 2.9％) were significantly lower than those in the control group (22.2％,27.0％,25.4％,19.0％,and 12.7％,P＜0.05).The average hospitalization days,total hospitalization expenses and intensity of antimicrobial use in the treatment group were significantly shorter/lower than those in the control group (P＜0.05).Glasgow coma scale scores (11.88±1.78) and good recovery rate (76.5％) in the treatment group were significantly higher than those in the control group (8.06±1.12,54.0％) two weeks after operation (P＜0.05).Good recovery rate (76.5％) in the treatment group was significantly higher than that in the control group (54.0％,P＜0.05).The mortality rate (5.9％) was significantly lower than that in the control group (17.5％,P＜0.05).Conclusion PICCO combined with intracranial pressure monitoring can effectively improve intracranial pressure,optimize cerebral perfusion,reduce complications such as traumatic cerebral infarction,neurogenic pulmonary edema,pulmonary infection and intracranial infection in patients with severe craniocerebral injury,thereby improving prognosis and reducing mortality;besides that,it can reduce patients' exposure to anti-brain infection,and the breadth and intensity of bacterial drugs can reduce the length of hospitalization and total cost of hospitalization,thereby reducing the burden of family and society.

Objective To evaluate the effectiveness of a chronic disease self-management program (CDSMP) in the Nanjing community. Methods From April to June 2016, the volunteer patients with chronic diseases from National Basic Public Health Services Plan were recruited and agreed to enter the CDSMP. A total of 42 self-management groups were established. The Nanjing CDSMP was based on the model of the Shanghai CDSMP developed by Stanford University. Questionnaire surveys, anthropometric measurements, and laboratory examinations were collected at 3 measurement moments (baseline, after 6 months, and after 12 months). Qualitative data were obtained from 1-2 participants in each self-management group. Paired t-tests, paired Chi-square tests, generalized estimating equation, and content analysis were used to evaluate the effectiveness of the CDSMP. Results Among 562 eligible patients, 548 completed 3 questionnaire surveys, physical measurements, and laboratory examinations. Sixty-six interviewees completed qualitative evaluations. Compared with baseline, the time of stretching or strengthening exercise and aerobic exercise; the scores on communication with the medical doctor; self-efficacy to manage symptoms and manage disease in general; quality of life in physical component summary and mental component summary; and rate of glucose control were all higher after 6 months and after 12 months interventions, whereas the score of fatigue; pain, health distress; social/role activities limitation; and the value of body weight, systolic blood pressure, and triglyceride were all decreased (all P values<0.01). The satisfaction rate of CDSMP in general, and content were 87.9%, 90.9%, and 83.3%, respectively. Conclusion Overall, the Nanjing CDSMP was successful in improving knowledge and self-management skills, increasing self-management behaviors, self-efficacy, health status, and quality of life, and decreasing body weight, blood pressures, and lipids. It is suggested that CDSMP may be widely used in Nanjing communities.
