Enteral Nutrition Support Does Not Improve PNI in Radiotherapy Patients with Locally Advanced Esophageal Cancer

Objective: The assessment of prognostic nutritional index (PNI) before and during radiotherapy is an important parameter for the prognosis in patients with cancer. In this study, enteral tube feeding (ETF) was used during radiotherapy in patients with EC. Dynamic changes of various nutritional indicators (including PNI) were monitored.

Methods: Patients with EC who underwent radiotherapy between June 2016 and July 2017 were enrolled. ETF was performing with the energy of 25?kcal?×?kg/d. Nutritional status were evaluated. Least significant difference (LSD) was used for multiple comparisons between groups.

Results: A total of 148 patients were admitted, including 51 patients fed via ETF. For patients who were not scheduled to nutritional support, significant difference were observed in albumin (ALB) (P?<?0.001), prealbimnin (PA) (P?=?0.05) and PNI (P?<?0.001) compared to levels before radiotherapy. In the patients fed via enteral tube, no significant difference were found in weight, BMI, ALB, retinol binding protein (RBP) and PA before and after radiotherapy, while PNI significantly decreased (P?<?0.001).

Conclusion: After preforming ETF with the energy of 25?kcal?×?kg/d in patients with EC during radiotherapy, PNI, the key nutritional index reflecting prognosis, significantly decreased.

Proteomic and bioinformatic analysis of condyloma acuminata: mild hyperthermia treatment reveals compromised HPV infectivity of keratinocytes via regulation of metabolism,differentiation and anti-viral responses

Background: Hyperthermia has proved successful in treating cutaneous human papillomavirus infectious diseases such as plantar wart and condyloma acuminata (CA). Moreover, this treatment provides improved therapeutic efficacy in these conditions as compared with conventional therapies.

Objectives: To investigate the global proteome changes in CA in response to hyperthermia and achieve a better understanding of the mechanisms of hyperthermia therapy against HPV-infectious diseases.

Methods: CA tissue was obtained from patients undergoing pathological examinations. Diagnosis was verified as based on results of both HE staining and HPV-DNA PCR assay. Hyperthermia was achieved with a 44?°C water bath. Differentially expressed proteins (DEPs) were identified by iTRAQ labeling, SCX chromatography and LC-MS/MS assay. Validation of proteomic results was performed using real-time qPCR and western blot, while bioinformatic analysis of DEPs was accomplished by R 3.4.1, STRING and Cytoscape softwares.

Results: In response to hyperthermia, a total of 102 DEPs were identified with 37 being upregulated and 65 downregulated. Among these DEPs, hyperthermia induced proteins involved with anti-viral processes such as OAS1, MX1, BANF1, CANX and AP1S1, whereas it inhibited proteins that participated in cellular metabolism, such as GALT, H6PD, EXOSC4 and EXOSC6; protein translation, such as RPS4Y1; as well as keratinocyte differentiation, such as KRT5, KRT27, KRT75, KRT76 and H2AFY2.

Conclusions: Hyperthermia inhibited enzymes and molecules responsible for metabolism modulation and keratinocyte differentiation in CA tissue, whereas it promoted factors involved in anti-viral responses. Such effects may, in part, contribute to the efficacy of local hyperthermia therapy against HPV infection.

Effect of Acupoints on Acupuncture-Moxibustion and its Therapeutic Mechanism

The clinical efficacy of acupuncture-moxibustion(AM) mainly depends on acupoints, but the relationship between the acupoints and AM remains unclear. Improving clinical efficacy and clarifying the mechanisms of AM is critical. We found that the specificity and sensitivity of acupoints, the skill of operation, and reasonable amount of stimulation can significantly improve the efficacy of AM. In addition, some studies have shown that Neural-Endocrine-Immune network and metabolites are involved in this process, clarifying the therapeutic mechanism of acupoints. Therefore, how to effectively use acupoints to improve the clinical efficacy of AM is one of the key issues in need of an urgent solution. In summary, this article reviewed the Chinese and English databases on the clinical efficacy and underlying mechanisms of acupoints to clarify the relationship between acupoints and AM efficacy and ultimately improve clinical efficacy through effective and rational use of acupoints.     

Comparison of microtransplantation,chemotherapy and allogeneic transplantation in post-remission therapy for Philadelphia chromosome-positive acute lymphoblastic leukemia

Patients with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph⁺ ALL) have poor prognosis, and the efficacy of chemotherapy plus tyrosine kinase inhibitors (TKIs) followed by mismatched donor stem cell infusion (microtransplantation, MST) has not been determined. We retrospectively summarized 45 patients including 11 undergoing MST with TKIs, 17 receiving allogeneic transplant and 17 undergoing chemotherapy with TKIs. Improved 4-year overall survival rate was observed in the MST group (91%) compared with either transplant group (31%, P = .005) or chemotherapy group (36%, P = .013). The MST group also had higher 2-year and 4-year leukemia-free survival rates (91% and 72%, respectively) compared with either transplant group (33%, P = .005 and 33%, P = .021, respectively) or chemotherapy group (41%, P = .017 and 31%, P = .023, respectively). 2-year and 4-year cumulative incidences of hematologic relapse were lower in the MST group (9% and 28%, respectively) compared with those in the chemotherapy group (56%, P = .025 and 67%, P = .034, respectively). In patients undergoing MST, donor microchimerism was detected (1.07 × 10^-5 to 6.6 × 10^-4 copies from 9 to 1499 days) in 7 patients, and donor/patient-derived HLA*0201/2402⁺WT1⁺CD8⁺ T cells were found from 0.05% to 0.67% in 6 patients. MST may provide a favorable treatment for patients with Ph⁺ ALL.
