In order to cultivate high-level medical talents, introducing information technology into medical teaching, the teaching faculty of the "Medical Functional Experiment" course constructed and explored an online-offline hybrid experimental problem-based learning (PBL) model guided by hypoxia pathophysiology problems. We explore the teaching method, implementation process, assessment, and effect evaluation of the experimental PBL model from the aspects of teaching objects, online teaching platform setting, and offline application, and also discuss its academic innovation points and application value. We hope to provide ideas for integrating the PBL concept into experimental teaching and help cultivate excellent innovative medical talents.

Objective:To observe and analyze the pathogenic genes and clinical phenotype characteristics of retinitis pigmentosa sinepigmento(RPSP).Methods:A retrospective clinical study. Two patients (proband) and five family members from two RPSP families admitted to Xiamen Eye Center of Xiamen University in December 2022 and Shenzhen Eye Hospital in July 2023 were included in the study. Two families have no blood relationship and were both Han Chinese. Detailed ocular and systemic medical history and specialized examinations were performed for all members, including color fundus photography, fundus autofluorescence (FAF), and full field electroretinogram (ff-ERG) examination. The peripheral venous blood of all members was collected, and genomic DNA was extracted. Pathogenic genes and their loci were screened using whole exome high-throughput sequencing technology. Sanger sequencing was used to verify the pathogenic genes in the two pedigrees. The pathogenicity of candidate variants was evaluated according to the American Society for American College of Medical Genetics and Genomics (ACMG) classification criteria and guidelines for genetic variants.Results:The two probands were male, aged 9 and 7 years, respectively. The main complaint was poor binocular vision for 6 and 3 years and poor treatment effect of amblyopia. The proband (Ⅱ2) in family 1 had a pale red color on the optic disc, with leopard-like changes in the posterior pole and thinner retinal arteries. FAF showed mottled fluorescence attenuation outside the macular vascular arch. There was no significant waveform in both bright and dark visual responses of ff-ERG. He also had 6-toed deformity of both feet, renal cysts, and a slightly overweight body. The clinical diagnosis was non-pigmentary retinitis pigmentosa. The proband of family 2 (Ⅱ1) had poor binocular vision in a dark environment and had atrophy lesions on the nasal side of the optic disc and leopard print like changes in the fundus. FAF showed uneven enhancement in the fovea. ff-ERG showed severe abnormalities in dark and light response, with significant decrease and delay in b-wave amplitude and latency. He had no other systemic abnormalities. The clinical diagnosis was binocular RPSP. There were no abnormal ocular and systemic manifestations in the two family members. Gene sequencing revealed a homozygous mutation (c.534+1G>T) of BBS2 gene, which was inherited from the mother and father respectively. Based on clinical manifestations and genetic testing results, the final diagnosis was Bardet Biedl syndrome. The genetic sequencing results confirmed a novel compound heterozygous mutation (c.950T>G: p. Leu317Arg missense mutation and c.849+1G>C splicing mutation) of BBS7 gene. His father (Ⅰ1) and mother (Ⅰ2) carried M1 heterozygous variants. Combined with the clinical manifestations and genetic testing results, the final diagnosis was Bardet-Biedl syndrome (BBS). Family 2 proband (Ⅱ1) carried the BBS7 gene C.950T>G (p.Leu317Arg) (M2) missense variation and C.849 +1G>C (M3) splice site variation. His father (Ⅰ1) and mother (Ⅰ2) carried M3 shear site variation and M2 missense variation, respectively. The two families all fit the autosomal recessive inheritance pattern, and the genotype and clinical phenotype were coseparated. According to ACMG guidelines, M1, M2 and M3 were all identified as possible pathogenic variants. Conclusions:BBS2 gene M1 homozygous variation and BBS7 gene M2, M3 complex heterozygous variation are the possible pathogenic genes in family 1 and family 2, respectively. Two families are affected by BBS and RPSP, respectively.

Pre- and post-treatment RANO scores were 4.00 (3.00, 7.00) score and 3.00 (2.00, 6.00) score respectively. Pre- and post-treatment RANO scores were positively correlated with ICP ONSD in the left eye ( r=0.55, P=0.001; r=0.60, P<0.001) , right eye ( r=0.54, P=0.001; r=0.46, P=0.009) and binocular eyes ICP ONSD ( r=0.45, P=0.010; r=0.37, P=0.043) . Conclusion:Intrathecal infusion chemotherapy for NSCLC-LM patients can cause a transient increase in ONSD and ICP, with the greatest effect at 1 hour after intrathecal infusion chemotherapy. RANO score is positively correlated with ICP ONSD before and after treatment, which can provide an important reference for evaluating the efficacy of intrathecal infusion chemotherapy.

Objective:To investigate the pharmacokinetics of cerebrospinal fluid pemetrexed following intrathecal injection chemotherapy in patients with leptomeningeal metastasis (LM) from lung adenocarcinoma and provide a basis for clinical intrathecal injection chemotherapy.Methods:A total of 21 patients with lung adenocarcinoma LM who underwent pemetrexed intrathecal injection chemotherapy via Ommaya capsule at Nanjing Drum Tower Hospital, Aiffilitated Hospital of Nanjing University Medical School from November 2019 to November 2022 were collected, and divided into 30, 40 and 50 mg groups ( n=10, n=4, n=7) according to pemetrexed dose. Cerebrospinal fluid was collected at 0, 0.5, 1, 2, 4, 6, 12, 24 and 48 h after the first intrathecal injection chemotherapy, and day 8 of each cycle for three groups. Reversed phase high performance liquid chromatography was used to determine the drug concentration in cerebrospinal fluid, to clarify the drug-related pharmacokinetic parameters, and to compare the differences in pemetrexed concentration among groups. Finally, cerebrospinal fluid pemetrexed concentration changes were observed and compared after different intrathecal injection chemotherapy cycles. Results:There were statistically significant differences in cerebrospinal fluid drug concentrations of patients in three groups at 0, 0.5, 1, 2, 4, 6, 12, 24 and 48 h after the first intrathecal injection chemotherapy (30 mg group: F=20.56, P<0.001; 40 mg group: F=27.06, P<0.001; 50 mg group: F=28.63, P<0.001), and there were statistically significant differences in the concentration of cerebrospinal fluid drugs in each dose group at 0.5, 1, 2, 4, 6 and 12 h compared to 0 h after intrathecal injection chemotherapy (all P<0.05). Compared to the 30 mg group, cerebrospinal fluid drug concentrations in the 50 mg group increased at 1, 2, 4, 6, 12 and 24 h after intrathecal injection chemotherapy, with statistically significant differences (all P<0.05). Pharmacokinetic analysis of cerebrospinal fluid pemetrexed showed that area under the concentration-time curve (AUC) 0-∞ of the 30, 40 and 50 mg groups were (5 696.12±283.32), (7 886.29±396.57), and (14 202.70±440.19) h·mg/L, respectively, with a statistically significant difference ( F=1 159.00, P<0.001) ; AUC 0-∞ increased in the 50 mg group compared to the 30 and 40 mg groups (both P<0.05) ; AUC 0-∞ increased in the 40 mg group compared to the 30 mg group ( P<0.05). The half-lives of three groups were (8.75±0.23), (11.29±0.59) and (16.42±1.23) h, respectively, with a statistically significant difference ( F=206.80, P<0.001) ; half-life was longer in the 50 mg group compared to the 30 and 40 mg groups (both P<0.05) ; half-life was longer in the 40 mg group compared to the 30 mg group ( P<0.05). The peak time of three groups were (1.55±0.10), (1.00±0.01), (1.43±0.11) h, respectively, with a statistically significant difference ( F=48.11, P<0.001) ; the peak time was shorter in the 40 and 50 mg groups compared to the 30 mg group (both P<0.05). Clearance of three groups were (7.02±2.46), (5.80±1.25) and (3.66±1.32) L/h, respectively, with a statistically significant difference ( F=6.02, P=0.009) ; clearance was decreased in the 50 mg group compared to the 30 mg group ( P<0.05). The peak concentration of three groups were (540.45±32.25), (820.75±46.47) and (1 014.78±64.96) mg/L, respectively, with a statistically significant difference ( F=207.70, P<0.001) ; peak concentration increased in the 50 mg group compared to the 30 and 40 mg groups (both P<0.05) ; peak concentration increased in the 40 mg group compared to the 30 mg group ( P<0.05). Cerebrospinal fluid drug concentrations were dynamically monitored after 4 cycles of intrathecal injection chemotherapy, in which cerebrospinal fluid pemetrexed concentrations in 30 mg group were (13.76±4.79), (11.41±7.08), (9.41±2.59) and (7.86±4.02) mg/L, respectively; 40 mg group were (14.45±6.59), (12.87±15.73), (11.24±2.48) and (9.09±3.38) mg/L, respectively; 50 mg group were (12.94±10.34), (9.72±7.62), (8.15±8.17) and (4.34±4.21) mg/L, respectively. There was a statistically significant difference in cerebrospinal fluid drug concentrations among different intrathecal injection chemotherapy cycles in 30 mg group ( F=4.04, P=0.016), and the cerebrospinal fluid drug concentration decreased in cycles 3 and 4 compared to cycle 1 (both P<0.05). There were no statistically significant differences in cerebrospinal fluid drug concentrations among different treatment cycles in 40 and 50 mg groups ( F=0.28, P=0.837; F=3.57, P=0.066) . Conclusion:Reversed phase high performance liquid chromatography method can effectively detect the pemetrexed concentration in cerebrospinal fluid; dynamic monitoring of cerebrospinal fluid pemetrexed concentration can provide a basis for the dosage and the treatment cycle of intrathecal injection chemotherapy in LM patients with lung adenocarcinoma.

In recent years, society has gradually shifted from a "fearful" approach of unscientific plan design, unbalanced resource protection and inadequate management experience leading to the spread of public panic and negative emotions to a "comfortable" approach of proactive prevention, precise control, information symmetry, scientific response and systematic treatment in the face of public health emergencies. College students are increasingly becoming the "key minority" to participate in crisis management. This is mainly due to their values in line with social ideals, their mobility in line with disciplinary practice and volunteerism, their knowledge accumulation in multi-disciplinary cross-fertilization, and their good cognitive thinking literacy, high information media literacy and perfect social support system. Therefore, this group has a strong comprehensive advantage in public health emergencies. Based on this background, combined with on-site investigation and interview feedback, this paper considered that this group can play an active role in normal prevention and early warning beforehand, information transmission and communication at the moment the event occur, corrective cognitive implementation and disposal in the event, and scientific research innovation and popularization afterwards, so as to better play an increasingly important leading demonstration effect in public health emergencies. At the same time, it can also encourage universities to take the initiative in the process of talent training to teach people according to the concept of "change according to the matter, advance according to the time and new according to the situation", and lead college students of different majors to maximize the pioneering effect of role models in public health emergencies.

Objective:To study the efficacy of different surgical methods in treatment of hilar cholangiocarcinoma (HCCA), and to analyze the factors affecting long-term prognosis of HCCA patients after surgical treatment.Methods:The clinical data of 105 patients who underwent surgical treatment for HCCA at the First Affiliated Hospital of Soochow University from April 2010 to October 2021 were retrospectively analysed. There were 58 males and 47 females, with age (64.2±10.6) years old. Data analysed included surgical treatments, postoperative pathological data, perioperative complications and survival on follow-up. The Kaplan Meier survival curve was plotted, and the log-rank test and Cox proportional hazard model were performed to analyze the key factors affecting long-term prognosis.Results:Of 105 patients, 4 (3.8%) patients died during the perioperative period, and 58 patients (55.2%) developed complications with included 32 (30.5%) patients with pleural effusion and 12 (11.4%) patients with biliary leakage. The follow-up data was available in 85 patients with the overall median survival time of 19 months, and the 1-, 3-, 5-year cumulative survival rates of 58.1%, 27.0% and 24.8% respectively. The 1-, 3-, and 5-year cumulative survival rates for the R 0 resection patients ( n=59) were 69.4%, 36.2%, 27.4%, respectively, which were significantly better than 49.4%, 12.3%, 0% for the R 1/2 resection patients ( n=20), and 0% for the palliative drainage patients ( n=6) (all P<0.05). Univariate analysis and Cox multivariate analysis showed that age ≥70 years ( HR=2.158, 95% CI: 1.175-3.965), preoperative CA19-9 level ≥1 015 U/ml ( HR=1.981, 95% CI: 1.009-3.894), resection margin ( HR=2.587, 95% CI: 1.371-4.881), and lymph node metastasis ( HR=2.308, 95% CI: 1.167-4.567) were independent risk factors for long-term prognosis of HCCA patients (all P<0.05). Conclusions:R 0 resection was an effective way to prolong survival of patients with HCCA. Age, preoperative CA19-9 level, resection margin and lymph node metastasis were related to long-term survival of HCCA patients.

ObjectiveTo understand the current situation and influencing factors of health service demands of new residents in Shanghai. MethodsFrom July to August 2020， a questionnaire survey was conducted in 1 358 new residents from 36 survey points in 7 districts of the city. The questionnaire included the basic medical insurance coverage in the inflow area， the current situation of medical demand and related influencing factors， and the demands for other health services. Results47.1%（562/1 194）of new residents did not choose to seek timely medical treatment when they were not feeling well. The main reason was that the working hours occupied the medical treatment time. Logistic regression analysis showed that the main factors affecting the medical needs in new residents were the average daily working hours， living area and type of residence， health status， physical examination and physical exercise， and the type of basic medical insurance. The demands of new residents for "health consultation of common diseases and frequently occurring diseases"， "health behavior intervention （such as smoking cessation and alcohol restriction）"， "medical guidance and publicity"， "accidental injury prevention （traffic， work， falling， etc.）" and "maintenance of legitimate rights and interests of health" were 57.1%（682/1 194）、41.3%（493/1 194）、34.9%（417/1 194）、32.2%（385/1 194） and 31.9%（381/1 194）， respectively.
