To study the pharmacokinetics of ~(131)I-Metuximab injection (Licartin) combined with transarterial chemoembolization (TACE) for treatment of hepatocellular carcinoma (HCC). MethodsLicartin (27.75 MBq/kg) and the mixture of anticancer drug and Lipiodol were sequentially administered with interval of 20 minutes to 15 patients with HCC via a transfemoral catheter.After the Licartin was administrated, the pharmacokinetic and biodistribution data were evaluated through venous blood samples,urine collections,and 4 γ-scintigraphies (SPECT) over 7 days. The pharmacokinetic parameters were determined from integration of the blood radioactivity-time curves using the SPSS 12.0 software. The tumor-no-tumor ratio (T/NT) was calculated by ROI. Absorbed doses in organ were estimated according to the medical internal radiation dose formalism. The biodistribution of licartin within patient's body at different time points was compared for various organs using analysis of variance for repeated measures, as well as the T/NT ratio. ResultsThe blood radioactivity-time curves followed the dynamics two-compartment model, with the major pharmacokinetic parameters including t_(1/2)α(1.96±1.65) h, and t_(1/2)α(19.07±5.91) h,and t_(1/2)β (57.09±10.92) h, and C_(max) 2.113×10~9min~(-1)·L~(-1), and AUC_(0-∞) 1.302×10~(11) h·min~(-1)·L~(-1), respectively. The accumulated urine radioactivity was 52.2% of administrated dosage during 144 h after administration. There were statistical significant difference of biodistribution of licartin and T/NT ratio between organs at different time points (F=6.583, P<0.01 and F=3.546, P<0.01). SPECT scans showed the significant accumulation of the radioconjugate in liver tumor and faint uptake in other organs for 14 days. Tumor-to-liver ratio decreased from 2.88±1.02 at 3 h to 1.64±0.40 at 168 h (n=7). Organ absorbed dose was (3.19±1.01) Gy in liver (n=12) and (0.55±0.09) Gy in red marrow (n=7). ConclusionLicartin combined with TACE for treatment of HCC is helpful to significantly accrete the radioconjugate in liver tumor, and protect normal organs from radiotoxictiy.

Aimed at developing new formulation, amorphous solid dispersion of itraconazole was prepared via hot-melt extrusion technology and compared with sporanox for improving its dissolution. According to the solubility parameter and glass transition temperature, Soluplus, Kollidon VA64, HPMCAS and Eudragit EPO were used as carriers. After screening the carriers by modulated temperature-differential scanning calorimetry(MT-DSC), the amorphous solid dispersion was prepared successfully and characterized by MT-DSC, polarized light microscope(PLM), X-ray powder diffraction(XRPD)and Fourier Transform InfraRed(FT-IR). Results suggested that the amorphous form of ITZ solid dispersion and whether the interaction between polymer and ITZ was appeared. Using 30% and 50% drug loading, solid dispersion were tested by in vitro dissolution and kinetic solubility tests. When using Soluplus(3 ∶7)as carrier and extrusion temperature of 170 ℃, dissolution rate of itraconazole was improved significantly compared to Sporanox. In 40 ℃, 75% RH condition, itraconazole in the solid dispersion was amorphous for 30 d with no crystal observed. MT-DSC indicated the molecular level miscibility between Soluplus and amorphous itraconazole was probably the main cause of solubilization. The result from this research help understanding the solublization of amorphous itraconazole and future formulation development.

OBJECTIVETo analysis the pathological demography in Chinese patients undergoing renal biopsy from our nephrology center.
METHODSBetween January 1979 and October 2000 in Jinling Hospital, Nanjing, China, 10,002 attempts of percutaneous renal were performed in patients with renal disease from 33 provinces of China. The pathological classifications were made according to the WHO criteria of 1982 for renal pathology or the modified WHO criteria of 1995 by a panel of pathologists and nephrologists during routine clinical-pathological rounds. The pathological demography between those specimens collected from 1979 - 1989 and those from 1990 - 1999 was compared.
RESULTSThe mean age of the 10,002 subjects undergoing renal biopsy was 31.4 +/- 13.0 years (ranging from 1 to 78 years), with a male to female ratio of 1.3:1; for the 592 renal transplant recipients, the mean age was 37.5 +/- 9.1 years (ranging from 16 to 66 years), with a male to female ratio of 2.36:1. Primary glomerular diseases (PGD) accounted for 71% of the total patients undergoing renal biopsies, secondary glomerular nephritis (SGN) 23%, tubular-interstitial diseases 3.2%, unclassified renal diseases 1.3%, hereditary and congenital renal diseases 1.0%, end stage renal diseases 0.96%, and recently realized or rare renal diseases 0.15%. IgA nephropathy (IgAN) was the most frequent pathological pattern (40%) of PGD, followed by mesangial proliferative lesion (MsPL) (30%), membranous nephropathy (MN) (10%), and focal segmental glomerulosclerosis (FSGS) (6%). Lupus nephritis (LN) was the most pathology common seen (74%) in SGN. During the 22 years of the study period, there was a steady increase in patients with SGN discovered during pathological evaluation of renal disorders. A rise in prevalence was found in IgA nephropathy, MN (both P < 0.001), crescentic glomerulonephritis (P < 0.0001), anti-GBM disease, and hemolytic-uremic syndrome/thrombotic thrombocytopenic purpura related renal damages (both P < 0.001). There was a decrease in endocapillary proliferative glomerulonephritis (P < 0.001) and IgM nephropathy (IgMN) (P < 0.01) from 1990 - 1999 as compared to 1979 - 1989. Infrequent renal pathological entities were also diagnosed in this group, including Niemann Pick disease, Fabry's disease, POEMS syndrome, and lipoprotein glomerulonephropathy.
CONCLUSIONSThis is the largest series of renal biopsy data in China, and therefore may reflect the demographic picture of renal diseases in this country. Changes in prevalence of renal pathological entities were reflected in this group of patients over the last 22 years. In primary glomerular diseases, IgA nephropathy is still the most frequently observed pathological pattern. In SGN, LN appeared the most often. Increased prevalence was found in anti-GBM nephritis and HUS/TTP.

ObjectiveTo investigate the efficacy and safety of camrelizumab monoclonal antibody combined with molecular-targeted therapy in elderly patients with unresectable or advanced hepatocellular carcinoma (HCC). MethodsA retrospective analysis was performed for the patients with unresectable/advanced HCC who attended six hospitals from January 1, 2019 to March 31, 2021, and all patients received camrelizumab monoclonal antibody treatment, among whom 84.8% also received targeted therapy. According to the age of the patients, they were divided into elderly group (≥65 years) and non-elderly group (<65 years). The two groups were assessed in terms of overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and immune-related adverse events (irAE). The chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups; the independent samples t-test was used for comparison of normally distributed continuous data, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. The Kaplan-Meier method was used for survival analysis, and the log-rank test was used for comparison of survival curves. Univariate and multivariate Cox proportional hazards regression analyses were used to determine the independent influencing factors for PFS and DCR at 6 months. ResultsA total of 99 HCC patients were enrolled, with 27 in the elderly group and 72 in the non-elderly group. The elderly group had an OS rate of 67.8%, an ORR of 44.4%, and a DCR of 74.1% at 12 months and a median PFS of 6.4 (95% confidence interval [CI]: 3.0 — 12.4) months, with no significant differences compared with the non-elderly group (all P>0.05). The median OS was unavailable for the elderly group, while the non-elderly group had an OS of 18.9 (95%CI: 13.0 — 24.8) months; there was no significant difference between the two groups (P=0.485). The univariate and multivariate Cox regression analyses showed that major vascular invasion (MVI) was an independent risk factor for PFS (hazard ratio [HR]=2.603, 95%CI: 1.136 — 5.964, P=0.024) and DCR (HR=3.963, 95%CI: 1.671 — 9.397, P=0.002) at 6 months, while age, sex, etiology of HBV infection, presence of extrahepatic metastasis, Child-Pugh class B, and alpha-fetoprotein>400 ng/mL were not associated with PFS or DCR at 6 months. For the elderly group, the incidence rates of any irAE and grade 3/4 irAE were 51.9% and 25.9%, respectively, with no significant differences compared with the non-elderly group (P>0.05), and skin disease was the most common irAE in both groups (39.4%). ConclusionCamrelizumab monoclonal antibody combined with molecular-targeted therapy has similar efficacy and safety in patients with unresectable/advanced HCC aged ≥65 years and those aged <65 years. MVI is associated with suboptimal response to immunotherapy and poor prognosis.
