Angiogenesis plays a critical role in growth and metastasis of lung cancer.The strongest tumor angiogenesis factor known is the vascular endothelial growth factor (VEGF).Therefore,anti-VEGF therapy which can restrain tumor angiogenesis is an important form of the targeted therapy of lung cancer.The expression of VEGF is also significant to the prognosis of lung cancer.

Objective To evaluate the changes of peripheral blood CD4+CD25+ regulatory T cells and its prognostic value in sepsis patients.MethodThe percentage of CD4+CD25+/CD4+ T cells were measured by flow eytometry present in peripheral blood in 36 sepsis patients on day 1,3 and 5 and 15 healthy people (control group).The changes of CD4+CD25+ regulatory T cells were analyzed in survivors group and non-survivors group respectively.Results There were 19 survivors and 17 non-survivors in sepsis patients.The percentage of CD4+CD25+/CD4+ T cells in survivors group and non-survivors group on day 1 was significantly lower than that in eontrol group [(12.42± 3.26)%,(12.96± 3.00)% vs (16.97 ± 3.66)%,P＜0.05].The percentage of CD4+CD25+/CD4+ T cells in survivors group and non-survivors group on day 3 were both signifieanfly higher than that on day 1 [(24.47±4.62)%vs (12.42±3.26)%,(26.61±3.85)%vs (12.96±3.00)%,P＜0.05].The percentage of CD4+CD25+/CD4+ T cells in survivors group on day 5[(18.28±4.28)%]was significantly lower than that on day 3 (P＜0.05),and the percentage of CD4+CD25+/CD4+ T cells in nonsurvivors group on day 5 were significantly higher than that on day 3(P＜0.05).There was no significant difference in the percentage of CD4+CD25+/CD4+ T ceils between survivors group and non-survivors group on day 1,3 respeefively(P ＞ 0.05),but the percentage of CD4+CD25+/CD4+ T cells in survivors group was significantly lower than that in non-survivors group on day 5 (P＜0.05).Conclusions The CD4+CD25+ regulatory T cells in sepsis patients decreases following by increase after onset.The persistent increase suggests the emergence of immunoparalysis,which is followed by high monaliy,The CD4+CD25+ regulatory T cells are valuable in evaluation of immune state and prediction the prognosis in sepsis patients.

MicroRNAs(miRNAs)are a class of small(22 nucleotides)non-coding RNAs which play important roles in diverse biological and pathological processes.The dysregulation of miRNA expression is closely related to the development and progression of malignant tumors in humans.DNA methylation is a kind of epigenetic modification in human genome.Both hypermethylation and hypomethylation of DNA are closely related to different kinds of tumors,including gastric cancer.

Objective:To retrospectively investigate the efficiency of Jinlong capsule combined with transarterial chemoemboli-zation for the treatment of advanced pancreatic carcinoma. Methods: Sixty advanced pancreatic carcinoma patients between January 2009 and May 2013 were randomly assigned into the experimental group (n=30, Jinlong capsule combined with transarterial chemoem-bolization) and the control group (n=30, transarterial chemoembolization). Both groups were subjected to superselective pancreas artery chemotherapy with GEMZAR at a dose of 1.0 g/m2. Results:The overall response rate (CR+PR) was 53.3%and the control rate was 70%(CR+PR+SD) (CR 0, PR 16, SD 5) in the experimental group, whereas those in the control group were 36.7%and 56.7%(CR 0, PR 11, SD 6), respectively. The short-term therapeutic efficacy was higher in the experimental group than in the control group (P<0.05). No significant difference in adverse reactions, including digestive reactions and myelosuppression, almost I-II degree, was observed be-tween the two groups (P>0.05). No significant difference in the Karnofsky performance status was observed between the two groups af-ter the treatment (P<0.05). The 24-month survival rate of the experimental group was 50.0%, whereas that of the control group was 33.3%(P<0.05). Conclusion:The application of Jinlong capsule combined with transarterial chemoembolization for the treatment of advanced pancreatic carcinoma showed good clinical effects. The patients also showed good tolerance to this treatment.

The technology of Magnetic Resonance Spectroscopy(MRS) is a newly-developed mean for analyzing some specific nucleus and their compounds making use of the principles of magnetic resonance and the effects of chemical shift. Currently, among MRS applications, proton magnetic resonance spectroscopy (1HMRS) is the most widely applied one developed from single voxel to three-dimensional multi-voxel scanning technique. It provides a lot of important information for clinical studies. This article mainly reviews the methods for absolute quantification measurement of brain metabolites using multi-voxel MRS.

Objective:To compare the efficacy of oblique lumbar interbody fusion (OLIF) and minimally invasive interbody fusion (MI-TLIF) for degenerative lumbar spondylolisthesis.Methods:Data of 40 patients with I-II degree single level degenerative lumbar spondylolisthesis from January 2018 to December 2018 were retrospectively analyzed. According to the operation procedure, they were divided into two groups: OLIF group and MI-TLIF group, and each group had 20 patients. There were 15 males and 5 females in the OLIF group, aged 50.3±8.8 years; and there were 13 males and 7 females in the MI-TLIF group, aged 51.7±8.7 years. According to the Meyerding's grade system, there were 16 patients of type I in the OLIF group and 15 cases in the MI-TLIF group; and there were 4 patients of type II in the OLIF group and 5 cases in the MI-TLIF group. The operation time, intra-operative hemorrhage, postoperative drainage, recessive blood loss and albumin loss were recorded. The CRP and ESR on the third day after operation, the VAS score and ODI score before and after operation were recorded. The lumbar lordosis (LL), fused segmental lordosis (FSL) and disc height (DH) before and after operation were recorded. The time of getting out of bed and walking and the hospital stay were recorded. Paired t-test was used to analyze the data.Results:Forty patients successfully underwent the operation. The operation time of OLIF group was 96±20 min, with intraoperative blood loss of 61±32 ml and postoperative drainage volume of 18±8 ml. The operation time of MI-TLIF group was 132±26 min, with intraoperative blood loss of 262±102 ml and postoperative drainage volume of 95±42 ml; and there was statistical difference between the two groups ( t=4.901, 8.404, 8.064; P< 0.001). On the third day after operation, the occult blood loss was 139±47 ml in the OLIF group and 486±192 ml in the MI-TLIF group; the albumin loss was 4.2±1.9 g/L in the OLIF group and 10.2±3.9 g/L in the MI-TLIF group; CRP was 34±11 mg/L in the OLIF group and 106±39 mg/L in the MI-TLIF group; ESR was 41±15 mm/1 h in the OLIF group and 71±24 mm/1 h in the MI-TLIF group, and there all were statistical differences between the two groups ( t=7.838, 6.184, 7.983, 4.675; P< 0.001). The VAS scores were 2.2±1.5, 1.8±1.3 and ODI scores were 14%±11%, 59%±17%, respectively. There was no significant difference between the two groups. The LL were 33.41°±9.25°, 32.07°±9.54°, FSL were 11.59°±5.09°, 10.61°±4.56° and DH were 10.35±2.30 mm, 10.85±1.85 mm, respectively. There was no significant difference between the two groups. The follow-up time was 13.5±2.3 months in the OLIF group and 14.1±2.8 months in the MI-TLIF group. Three patients in the MI-TLIF group had radiation pain in the lower extremity on the third day after operation, which relieved after NSAID drugs and mannitol treatment. In the group of OLIF, the skin temperature of the left lower extremity increased in 1 case on the first day after operation, in which sympathetic chain injury was considered, and the patient recovered after 2.5 months; in the group of OLIF, the numbness in the front of the left thigh and the weakness of flexion of the hip was found in 3 cases, in which the edema or injury of the psoas major muscle was considered. Conclusion:Compared with MI-TLIF in the treatment of I, II degree single segment degenerative lumbar spondylolisthesis, OLIF has the advantages of shorter operation time, less intraoperative and postoperative blood loss, lower inflammation index, earlier time to get out of bed and shorter hospital stay. However, the outcomes of the two surgeries were similar.

There is increasing interest in the clinical use of flattening filter-free (FFF) beams. In this study, we aimed to investigate the dosimetric characteristics of volumetric modulated arc radiotherapy (VMAT) with FFF beams for nasopharyngeal carcinoma (NPC). Ten NPC patients were randomly selected to undergo a RapidArc plan with either FFF beams (RA-FFF) or conventional beams (RA-C). The doses to the planning target volumes (PTVs), organs at risk (OARs), and normal tissues were compared. The technical delivery parameters for RapidArc plans were also assessed to compare the characteristics of FFF and conventional beams. Both techniques delivered adequate doses to PTVs. For PTVs, RA-C delivered lower maximum and mean doses and improved conformity and homogeneity compared with RA-FFF. Both techniques provided similar maximum doses to the optic nerves and lenses. For the brain stem, spinal cord, larynx, parotid glands, oral cavity, and skin, RA-FFF showed significant dose increases compared to RA-C. The dose to normal tissue was lower in RA-FFF. The monitor units (MUs) were (536 ± 46) MU for RA-FFF and (501 ±25) MU for RA-C. The treatment duration did not significantly differ between plans. Although both treatment plans could meet clinical needs, RA-C is dosimetrically superior to RA-FFF for NPC radiotherapy.
