ObjectiveTo evaluate the therapeutic effect of liver transplantation (LT) combined with adenovirus-mediated delivery of herpes simplex virus thymidine kinase / ganciclovir (ADV-TK/GCV) in treatment of patients with hepatocellular carcinoma (HCC), so as to benefit more patients with HCC beyond the Milan criteria. MethodsThe clinicopathologic data of patients with HCC underwent LT by the author team since 2007 were collected and analyzed. The patients were assigned into simple LT group and LT+ADV-TK/GCV group. The 5-year cumulative overall survival rate and relapse free survival rate of all LT patients and the patients with LT beyond the Milan criteria by simple LT and LT+ADV-TK/GCV therapy were compared. Meanwhile, Cox regression was used to analyze the risk factors affecting long-term overall survival rate and relapse free survival rate of all patients with HCC after LT. ResultsA total of 216 patients eligible for inclusion were collected in this study, including 134 patients in the simple LT group and 82 patients in the LT+ADV-TK/GCV group, 162 of whom beyond the Milan criteria, including 101 patients underwent the simple LT and 61 patients underwent the LT+ADV-TK/GCV. There were no statistical differences in the baseline data between the simple LT and LT+ADV-TK/GCV in all patients and patients beyond the Milan criteria (P>0.05). There were no statistical differences in 5-year overall survival rate and relapse free survival rate of all patients with HCC (P>0.05). The 5-year cumulative overall survival rate of the LT+ADV-TK/GCV group was better than that of the simple LT group in the patients beyond the Milan criteria (χ2=4.11, P=0.047), but it was not found that the 5-year cumulative relapse free survival rate had statistical difference (27-month survival time as the critical value, P=0.46, P=0.06). Cox regression multivariate analysis results showed that the larger cumulative tumor diameter, the preoperative elevated serum alpha fetoprotein (>400 μg/L), later TNM stage, and without combination of ADV-TK/GCV therapy increased the probability of shorter overall survival of patients after LT; and the patient’s older age, the larger cumulative tumor diameter, and later TNM stage increased the probability of shorter relapse free survival after LT, and it was not found that the combination of ADV-TK/GCV therapy had an impact on the relapse free survival. ConclusionLT combined with ADV-TK/GCV therapy can obviously improve overall survival among patients beyond the Milan criteria, more patients with advanced HCC will be candidates for LT combined with ADV-TK/GCV therapy.

Objective To investigate the biological characteristics and clinical significance of cuproptosis-related genes in lung adenocarcinoma (LUAD) based on the multi-omics data from The Cancer Genome Atlas. Methods The cuproptosis-related genes were obtained from a study published in Science in March 2022. The whole genome data were used to reveal the mutation spectrum and copy number variation landscape of cuproptosis-related genes in LUAD and analyze its effects on transcriptome expression. Cuproptosis-related genes were annotated using Metascape analysis to further understand the pathways or functions in which these genes were involved. Subsequent univariate Cox analysis and Kaplan-Meier methods determined the prognosis of these genes in LUAD patients, and CellMiner analysis were used to identify those potential anticancer drugs for potentially targeting cuproptosis-related genes. Results Cuproptosis-related genes were less frequently mutated in LUAD, and the effect of gene mutations on transcriptomic expression may depend on the type of mutation. Gene copy number variation was an important factor resulting in the disordered expression of cuproptosis-related genes. The 16 cuproptosis-related genes were mainly involved in glyoxylate metabolism and glycine degradation, copper ion entry, proteolitidylation, cellular amino acid catabolism process, oxidative stress response, etc. Among them, 6 genes (DLD, FDX1, DLAT, DLST, PDHA1, CDKN2A) were prognostic risk genes in LUAD. The CellMiner analysis suggested that 13 drugs were associated with 7 cuproptosis-related genes and they might be potential anticancer drugs for potentially targeting cuproptosis. Conclusion This study reveals the biological characteristics and clinical significance of cuproptosis-related genes in LUAD, and provides some reference and theoretical basis for the subsequent research of cuproptosis in cancer.
Objective To evaluate the efficacy and safety of tetramethylpyrazine (TMP) for diabetic peripheral neuropathy (DPN). Methods Randomized controlled trials were identified from CBM (1978-2003.3), TCMLRS (1980-2003.3), Medline (1970-2003.3), EMbase (1970-2003.3) and Cochrane Library (issue 3, 2003). We handsearched Journal of Traditional Chinese Medicine (1990-2002), New Chinese Medicine (1990-2002), Chinese Journal of Integrated Traditional and Western Medicine (1990-2002) and Research of Traditional Chinese Medicine (1990-2002). Papers of the controlled trials of clinical therapeutic studies on DPN treatment by Chinese medicine herb TMP were included and analyzed according to the criteria of the Cochrane Handbook in 1997. Results Six RCTs involving 669 patients were included, with all trials of low methodological quality. Meta-analysis indicated TMP was more effective than western medicine on pain or numbness of extremities of DPN [The pooled OR = 10.12, 95%CI (6.70 to15.28), P=0.000] and motor nerve conduction velocity change of common peroneal nerves and median nerves . Only one trial reported the side effects of TMP, such as dizziness and headache. Conclusions Based on the review, TMP infusion may have positive effect on DPN. However, the evidence is not b enough due to the general low methodological quality, so we can’t draw a reliable conclusion about the effects of TMP for DPN at the moment. Further large randomized, double blind, placebo-controlled trial are needed.
Objective To evaluate the therapeutic efficacy and safety of trazodone versus alprazolam for generalized anxiety disorder (GAD). Methods After the third day of a three-day screening period, 60 patients with generalized anxiety disorder were randomly assigned to the trazodone group (30 patients, 50-150 mg/d), and alprazolam group (30 patients 1.2-4 mg/d) for 4 weeks. Patients and their doctors were blind. Data were analyzed by SPSS 10.0 and intention-to-treat analysis. Results The total effective rate of trazodone was 77% (23/30), while alprazolam was 70% (21/30) (Pgt;0.05) .No difference was seen for adverse events. None was lost to follow in the two groups. Conclusions Trazodone appears to be as effective as alprazolam in treating generalized anxiety disorder. Adverse events may include confusion and loss of appetite, but patients are able to tolerate these.

ObjectiveTo explore the values of CA19-9, CA242, CEA, and CA125 single or combined detection on clinical diagnosis and prognosis for patients with pancreatic cancer. MethodsSerum tumor markers CA199, CA242, CEA, and CA125 of 63 patients with pancreatic cancer, 33 patients with cancer of bile duct, and 27 patients with benign pancreatic disease were detected, and those patients were followed up after operation. ResultsThe levels of CA19-9, CA242, CEA, and CA125 in patients with pancreatic cancer were significantly higher than those in patients with benign pancreatic disease and cancer of bile duct (Plt;0.05). The sensitivity of CA19-9 alone was the highest in the four tumor markers for the patients with pancreatic cancer 〔79.4% (50/63)〕, but the specificity (61.9%) was lower than that of CA242 (83.3%) and CEA (80.0%). The specificity of combined detection of CA199+CA242+CEA was the highest 〔93.3% (56/60)〕. The level of CA19-9 in carcinoma of body/tail of pancreas was significantly higher than that of carcinoma of pancreas head or whole pancreas (Plt;0.05). The serum levels of CA19-9 and CA242 in patients with stage Ⅳ were significantly higher than those in stage Ⅰ or Ⅱ/Ⅲ (Plt;0.05). Fifteen patients were lost to follow up, 48 patients were followed up 2－12 months with an average 6 months. The levels of CA242 and CA199 in patients with pancreatic cancer on 0.5 month and 3 months after operation were lower than those before operation (Plt;0.05). ConclusionsSingle detection of CA19-9 can improve the diagnostic sensitivity, and combined detection of tumor markers CA199+CA242+CEA can improve the diagnostic specificity. CA19-9 or CA242 is a valuable marker for evaluating treatment effects and estimating prognosis.
ObjectiveTo study the clinical manifestations, pathologic characteristics, imaging features, diagnosis and treatment of adenomas of extrahepatic bile duct.MethodsTwo cases of adenomas of extrahepatic bile duct in our hospital and 14 cases reported in the literatures were analyzed retrospectively.ResultsThe patients’(male 5, female 11) mean age was 58.4 years (range 21-85). The main manifestations included jaundice (n=11), abdominal pain (n=8),fever (n=6),dyspepsia (n=4),body weight loss (n=3) and claycolored stool (n=1). The locations of tumors were in the left hepatic duct (n=1), right hepatic duct (n=3), hepatic common bile duct(n=3）,the junction of cystic duct and common bile duct (n=1），distal common bile duct (n=8). The pathologic types were tubular adenomas (n=5), papillary (villous) adenomas (n=10),and mucous adenoma (n=1). All the patients underwent surgical therapy. The tumors were identified by postoperative histopathologic examination.ConclusionIt is difficult to correctly diagnose adenomas of extrahepatic bile duct before operation, because the clinical manifestations are usually atypical. The definite diagnosis should depend on histopathologic examination. It is the key to completely resect the tumors. Postoperative followup should be done on regular basis.
