Objective To explore the change of cellular immune function in renal cancer patients adopting thymopetidum (TP-5) combined with cytokine-induced killer cells (CIK) in peroperative period,and evaluate its curative effect.Methods Forty-one cases of Ⅰ-Ⅲ stage renal cancer patients adopting CIK treatment postoperatively were enrolled in this study for retrospective analysis.According to applicating condition of TP-5,the patients were divided into two groups:16 cases of combination group (TP-5+CIK) and 25 cases of CIK group.The patients in combination group were given TP-5 intramscular injection everyday from preoperative 1 d to postoperative 3 weeks,once a day.Peripheral blood mononuclear cell was collected in the patients of two groups,which was cultivated for 2 weeks and then transfused.Fasting peripheral blood 1 week (before collected peripheral blood mononuclear cell),3 weeks (before CIK retransfusion),4 weeks(after CIK retransfusion for 1 week) and 5 weeks(after CIK retransfusion for 2 weeks) after operation were examined,the peripheral blood T cell subgroups (CD3+,CD4+,CD8+) and nature killer cell (NK cell) levels were detected using flow cytometry.Results At 1 week and 3 weeks (before CIK) after operation,the levels of CD3+,CD4+/CD8+ and NK cell in combination group were significantly higher than those in CIK group:1 week after operation:0.542 ± 0.063 vs.0.491 ± 0.054,0.94 ± 0.09 vs.0.90 ± 0.12,0.247 ± 0.025 vs.0.223 ± 0.033;3weeks after operation:0.641 ±0.058 vs.0.587 ±0.062,1.71 ±0.13 vs.1.02 ±0.07,0.319 ±0.038 vs.0.264 ± 0.047).There were significantly differences (P＜ 0.05).At 4 weeks after operation,the levels of CD3+,CD4+/CD8+ and NK cell in combination group were significantly higher than those in CIK group:0.698 ± 0.041vs.0.649 ± 0.050,2.01 ± 0.11 vs.1.64 ± 0.09,0.331 ± 0.029 vs.0.289 ± 0.034.There were significantly differences (P ＜ 0.05).At 5 weeks after operation,the levels of CD3+,CD4+/CD8+ and NK cell in two grotups were no significant difference (P ＞ 0.05).At 4 and 5 weeks after operation,the levels of CD3+,CD4+/CD8+ and NK cell in two groups were significantly higher than those of 3 weeks after operation (P ＜ 0.05).None of patients occurred acratia,hyperpyrexia,shivering and so on.Conclusions The application of TP-5 treatment in peroperative period can promote the recovery of cellular immune function,which has synergistic effect with CIK.The value of TP-5 is worthy of promotion.

In order to study the effect of self-made liver preservation solution on liver preservation by comparing with UW solution and HC-A solution, the self-made liver preservation solution (SM) and perfusion solution were prepared under the aseptic conditions. The isolated non-circulated perfu-sion rat liver model was established. According to the different preservation solutions, the rats were randomly divided into UW group, SM group and HC-A group. The three groups were divided into 6subgroups according to the preservation duration (n=6 in each group). The transferase in liver perfu-sion solution and intercellular adhesion molecule-1 (ICAM-1) and nitric oxide (NO) in liver tissues were determined at 2, 8 and 24 h respectively. The results showed that the levels of alanine aml- notransferase (ALT) and aspartate aminotransferase (AST) had no significant difference between SM group and UW group, but significantly lower than in HC-A group. The levels of ICAM-1 and NO were increased simultaneously in SM group and UW group (P＞0.05), but there was significant dif-ference as compared with HC-A group (P＜0.05). At the same time point, the level of ICAM-1 was higher in SM group than in UW group, but NO was lower. The preservation effect of SM solution is the same as UW solution, but better than HC-A solution.

Objective:To evaluate the feasibility and efficacy of 68Ga-PSMA PET/CT-guided targeted prostate biopsy for the diagnosis of clinically significant prostate cancer(csPCa). Methods:This retrospective analysis allocated 89 patients with elevated PSA levels between 4.0-20.0 ng/ml to PET group(n=48) or TRUS group(n=41) between September 2017 and June 2019. Patients with PSMA-avid lesions (SUV max≥8.0) underwent PET-TB via a single-puncture percutaneous transgluteal approach (n=19), while patients with negative PSMA-PET underwent systematic TRUS-GB (n=29). Patients in the TRUS group who did not get 68Ga-PSMA PET/CT examination underwent TRUS-GB directly (n=41). The mean age, prostate volume, PSA value of PET group and TURS group were (71.2±9.1) years vs. (68.0±12.0) years, (62.9±29.1)ml vs. (65.4±38.9)ml , 8.8(6.6, 13.6) ng/ml vs. 9.8(7.1, 13.1)ng/ml, respectively (all P>0.05). The diagnostic efficacy and difference of PCa and csPCa between the two groups were compared. PET-TB adopts a new mode of percutaneous gluteus approach and carries out precise image fusion of PSMA-PET/CT and pelvic CT in the same machine and in the same position (prone position). Under the direct guidance of CT, the biopsy is performed with only one precise puncture. Results:PCa and csPCa were detected in 27/89(30.3%)and 20/89(22.5%)in all patients. PET group detected significantly more cases of PCa and csPCa than those of TRUS group [PCa: 41.7%(20/48) vs. 17.1%(7/41), χ2=6.328; csPCa: 33.3%(16/48) vs. 9.8%(4/41), χ2=7.055, P<0.01]. Of 19 patients with PSMA-PET positive, PET-TB detected 16 cases of PCa(84.2%) by a single needle puncture, and the proportions of cancer tissues were ≥80% in 2, 50%-79% in 8, and <50% in 6 cases. Among these, Gleason score was underestimated by biopsy histopathology in 2 patients. Of 3 patients with PET-TB negative, 1 case of low-risk PCa(Gleason 3+ 3) was detected by complementary TRUS-GB. The sensitivity, specificity, positive predictive value, negative predictive value, accuracy of 68Ga-PSMA PET/CT(SUV max≥8.0) for the diagnosis of csPCa were 73.9%(14/19), 93.1%(27/29), 87.5%(14/16), 81.3%(26/32)and 85.4%(41/48), respectively. For PET-TB, only one patient had slight symptoms of haematuria after the puncture, no cases of hematochezia, hemospermia, urinary retention or pelvic infection were observed. Conclusions:68Ga-PSMA PET/CT is a feasible novel puncture technique that may serve as a triage tool for prostate biopsy, and PET-TB may improve the detection rate of csPCa compared with TURS-GB, especially in patients with serum PSA 4.0-20.0 ng/ml.

Chronic atrophic gastritis (CAG) and gastric intestinal metaplasia (GIM) significantly increase the risk of gastric cancer. Blocking the development of CAG and GIM would help to decrease the incidence of gastric cancer. It was revealed that eradication of Helicobacter pylori could reverse gastric mucosa atrophy. Recent studies reported that GIM could be reversed to a certain extent. Clinical studies demonstrated that Lamb′s tripe extract and vitamin B12 capsule exhibited significant reversal effects on GIM. The present study systemically reviewed the diagnosis and treatment of CAG and clinical application of Lamb′s tripe extract and vitamin B12 capsule, and established the specialist instruction that would guide the reversal treatment of CAG and GIM.

Objective: To investigate the feasibility and dosimetric characteristics of using dual-arc volumetric modulated arc therapy and multiple partial-arc VMAT for T3 lung cancer. Methods: From June 2016 to May 2018, thirteen lung cancer patients with large planning target volume were replanned with dual full arcs VMAT(F-VMAT) and six partial-arc s VMAT(P-VMAT)on RayStation v4.5 RayArc function.PTV volume median was 550.9cm³(ranged 402.2-834.8cm³) and to a prescribed dose of 60 Gy in 30 fractions.Equivalent target coverage was required for all plans, and clinical goals were evaluated using various dose-volume metrics.These included PTV dose conformity, mean lung/heart dose, lung V₅, V₁₀, V₂₀, V₃₀, heart V₃₀ and V₄₀, and Dmax of spinal canal.The total monitor units (MUs) were also examined. Results: All VMAT plans satisfied the treatment criteria.F-VMAT achieved better homogeneity index(HI) and MUs than P-VMRT(t=-3.904, P=0.002), and the conformal number(CN) of tumor volumes was likely clinically indistinguishable.However, F-VMAT significantly reduced lung V₅, V₁₀ and mean lung dose[V5: (51.31±5.36)% vs.(43.44±5.28)%, t=6.908, P=0.00; V10: (38.34±3.26)% vs.(34.05±3.74)%, t=4.632, P=0.001; Dmean: (1 449±117.19)cGy vs.(1 375.38±148.98)cGy, t=4.93, P=0.00], and heart dosimetric parameters were also observed in favor of P-VMRT[V₃₀: (20.6±10.4)% vs.(16.4±8.9)%, t=3.822, P=0.02; V₄₀: (14.6±7.5)% vs.(11.88±7.1)%, t=3.096, P=0.009; Dmean: (1 442.9±651.2)cGy vs.(1 263.5±605.6)cGy, t=3.986, P=0.02], and there were no statistically significant differences in lung V₂₀, V₃₀ and spinal cord Dmax between the two groups(all P>0.05). Conclusion VMAT is an effective treatment for stage T3 lung cancer patients.The primary advantage of P-VMAT was the reduction in low dose area and decreased risk of symptomatic radioactive lung injury.It may be a priority for pulmonary malignancy patients with the large planning target volume.
