Objective:To observe the clinical characteristics of elderly patients with liver failure complicated with fungal infection,and to analyze the factors influencing the prognosis.Method:117 cases of elderly patients with liver failure,who were treated in our hospital from May 2013 to May 2015,were selected as object,according to whether combined with fungal infection,the patients were divided into Fungal infection group (57 cases) and non fungal infection group (60 cases).The differences of liver function index,treatment effective rate and mortality were observed between the two groups;To compare the prognosis of patients with different clinicopathological features,and to explore the factors influencing the prognosis of patients.Results:The scores of ALT,AST and DBIL in patients with fungal infection were significantly higher than those without fungal infection,and the difference was statistically significant (P＜0.05);The effective rate of the treatment group was significantly lower than that of the non fungal infection group,the mortality rate was higher than that of the non fungal infection group,the difference was statistically significant (P＜0.05);The death rate of patients with age was more than or equal to 70 years of age,with diabetes,with fungal infection were higher (P＜0.05);Logistic regression analysis showed that combined with diabetes mellitus,combined with fungal infection was an independent prognostic factor for elderly patients with liver failure (OR=2.982,4.817,P＜0.05).Conclusion:Liver function injury is severe in elderly patients with liver failure,the mortality rate is high,and fungal infection is more serious,and diabetes and fungal infection are risk factors for mortality.

In order to observe the effect of Bushenantai recipe on the expression of endometrial leukemia-inhibitory factor (LIF) in mice with embryonic implantation dysfunction (EID), 120 Kunming mice post coition were randomized into three groups: normal control group, model group and traditional Chinese medicine group (TCM group) (n=40 in each group). Uterus was collected on the pregnancy day (Pd) 4, 5, 6 after an intravenous injection of Evan's blue. The endometrium was dyed by Evan's blue and the mean points of response were observed on Pd 5. The expression of LIF mRNA and protein was detected by RT-PCR and immunohistochemistry respectively and analyzed statistically by image system. The results showed that the number of implantation sites in model group was remarkably less than in normal control group and TCM group. There was no significant difference between normal control group and TCM group. The expression of LIF mRNA and protein in model group was delayed. Bushenantai recipe could increase the expression of LIF mRNA and protein in endometria of mice with EID. It was suggested that Bushenantai recipe could improve embryo implantation of mice with EID by promoting the endometrial LIF expression and endometrial decidualization.

The clinical effects of acupuncture on idiopathic male infertility in sperm parameter and on therapeutic results in assisted reproductive technology were investigated. 22 patients failed in intracytoplasmic sperm injection (ICSI) with idiopathic male infertility were treated with acupuncture twice weekly for 8 weeks, followed by ICSI treatment again. The sperm concentration, motility, morphology, fertilization rates and embryo quality were observed. Quick sperm motility after acupuncture (18.3% +/- 9.6%) was significantly improved as compared with that before treatment (11.0% +/- 7.5%, P < 0.01). The normal sperm ratio was increased after acupuncture (21.1% +/- 10.4% vs 16.2% +/- 8.2%, P < 0.05). The fertilization rates after acupuncture (66.2%) were obviously higher than that before treatment (40.2%, P < 0.01). There was no significant difference in sperm concentration and general sperm motility between before and after acupuncture. The embryo quality after acupuncture was improved, but the difference between them was not significant (P > 0.05). Acupuncture can improve sperm quality and fertilization rates in assisted reproductive technology.

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.
