RESUMEN
To evaluate the effect of autologous blood transfusion (ABT) on hematopoietic stem cells through the observation of the changes in the number and activity of bone marrow CD34+ cells after preoperative autologous blood donation (PABD). Rabbit bone marrow specimens were collected preoperatively (T2), 6 h postoperatively (T3), and 24 h postoperatively (T4). Next, the percentages of CD34+ cells, the cell cycle, and the relative expression of telomeric DNA were measured in each group of rabbits. Peripheral blood specimens were collected before PABD (T1) and at T4 to measure reticulocytes. At T3 and T4, the percentages of CD34+ cells and the expressions of telomeric DNA were significantly higher, and the percentages of cells in the G1 phase were significantly lower in each experimental group compared with those in the blank control group (group A) (P<0.05). Compared with the surgical blood collection group (group C), the CD34+ cells and the expressions of telomeric DNA were significantly higher, and the percentages of cells in the G1 phase were significantly lower in the preoperative autologous whole blood group (group D) and the preoperative autologous blood component group (group E) (P<0.05). Compared with group D, the CD34+ cells and the expressions of telomeric DNA were significantly lower, and the percentages of cells in the G1 phase were significantly higher in group E (P<0.05). At T4, the reticulocyte percentages in the surgery group (group B) and group C were significantly higher than in group E and group D, and the reticulocyte percentages in group E were higher than in group D (P<0.05). This study's findings indicated that ABT suppressed bone marrow hematopoiesis, while autologous blood component transfusion had less of an effect than that of whole blood transfusion. Therefore, PABD blood component transfusion would be superior to autologous whole blood transfusion.

To evaluate the impacts of guanidinoacetic acid (GAA) and coated folic acid (CFA) on growth performance, nutrient digestion and hepatic gene expression, fifty-two Angus bulls were assigned to four groups in a 2 × 2 factor experimental design. The CFA of 0 or 6 mg/kg dietary DM folic acid was supplemented in diets with GAA of 0 (GAA-) or 0·6 g/kg DM (GAA+), respectively. Average daily gain (ADG), feed efficiency and hepatic creatine concentration increased with GAA or CFA addition, and the increased magnitude of these parameters was greater for addition of CFA in GAA- diets than in GAA+ diets. Blood creatine concentration increased with GAA or CFA addition, and greater increase was observed when CFA was supplemented in GAA+ diets than in GAA- diets. DM intake was unchanged, but rumen total SCFA concentration and digestibilities of DM, crude protein, neutral-detergent fibre and acid-detergent fibre increased with the addition of GAA or CFA. Acetate:propionate ratio was unaffected by GAA, but increased for CFA addition. Increase in blood concentrations of albumin, total protein and insulin-like growth factor-1 (IGF-1) was observed for GAA or CFA addition. Blood folate concentration was decreased by GAA, but increased with CFA addition. Hepatic expressions of IGF-1, phosphoinositide 3-kinase, protein kinase B, mammalian target of rapamycin and ribosomal protein S6 kinase increased with GAA or CFA addition. Results indicated that the combined supplementation of GAA and CFA could not cause ADG increase more when compared with GAA or CFA addition alone.

Our long-term goal is to improve chick health and reduce the use of antibiotics in the poultry industry via maternal effects. To link jejunal microbes with chicks' different immune levels and growth performance in our previous research, this study investigated jejunal microbes, jejunal inflammation, and immune responses based on a comparison between different groups. Newly hatched Hy-Line chicks were allotted into 3 groups: a chick control group (cCON), a ciprofloxacin lactate treatment group (Cipro)-the chicks of the cCON and Cipro groups were hatched from laying breeder hens given a basal diet-and a 5-wk ß-carotene, curcumin, allicin, and sodium butyrate supplementation group (cCCAB), wherein chicks hatched from laying breeder hens. All groups were fed the same diet for 4 wk; the Cipro group was given ciprofloxacin lactate in drinking water continuously. At the end of the experiment, the results demonstrated that the jejunal microbes of the Cipro group showed significant changes in alpha and beta diversity, and in taxonomy at phylum and genus levels. Statistically, a total of 67 significantly enriched (P < 0.05) taxa were identified between groups by linear discriminant analysis effect size; Firmicutes was significantly enriched (P < 0.05) in the cCCAB group, 65 taxa were significantly enriched (P < 0.05) in the Cipro group, and 32 of the 65 enriched (P < 0.05) taxa were in the Proteobacteria phylum of the Cipro group. Levels of lipopolysaccharide in jejunal content, and nuclear factor kappa-B, and tumor necrosis factor-α in jejunums of the Cipro and cCCAB groups were increased (all P < 0.05) compared to those in the cCON group. There was obvious neutrophil infiltration and upregulated (all P < 0.05) IL-6 mRNA in the Cipro group jejunums compared to the cCON and cCCAB groups. The expression of PSME3 and PSME4 genes was upregulated (all P < 0.05) in the cCCAB group compared to the cCON and Cipro groups. In conclusion, ciprofloxacin lactate administration led to potential hazards in health and growth in chicks via microbial disturbances-induced jejunal inflammation, and laying breeder hens dietary supplementation with ß-carotene, curcumin, allicin, and sodium butyrate could enhance jejunal immunity of their offspring via the interaction between host innate immunity selected microbial colonization and microbiota educated adaptive immunity.

This study evaluated the growth performance, immunity, and jejunum morphology of chicks hatched from laying breeder hens given dietary additive supplementation, as well as chicks receiving direct antibiotic supplementation in early life. Hy-line breeder hens were allotted to 2 groups with 3 replicates. A control group (CON) was fed a basal diet, and the treatment group (CCAB) received ß-carotene, curcumin, allicin, and sodium butyrate in addition to basal diet for 5 wk. Breeder-hen eggs were collected and hatched. The chicks hatched from the CON group were assigned to 2 treatments: a chick control group (cCON) and a chick treatment group (Cipro) given ciprofloxacin lactate into drinking water; the cCON group, Cipro group, and the chicks hatched from the CCAB group (cCCAB) were fed the same diet for 4 wk. The results demonstrated that there were significant differences between the CON and CCAB groups in the serum levels of IgA, IgG, IgM (triple P < 0.01), lysozyme (P < 0.05), and ß-defensin (P < 0.05). The body weights of the cCCAB group's chicks increased at 1, 7, and 28 D of age (P < 0.05, P < 0.05, P < 0.01, respectively), and those of the Cipro group's chicks increased at 7 and 21 D of age (P < 0.01, P < 0.05). The tibial lengths of the cCCAB group's chicks increased at 1, 7, 14, 21, and 28 D of age (P < 0.01, P < 0.05, triple P < 0.01), and the lengths in the Cipro group increased at 7 and 14 D of age (P < 0.01, P < 0.01). Intestinal development, including intestinal length, jejunum morphology, and IgA positive cells, helps to explain these results. The breeder eggs from the CCAB group had higher IgG (P < 0.05) and IgM (P < 0.05) levels in the egg whites and higher IgA, IgG, and IgM levels (triple P < 0.01) in the egg yolks. In conclusion, ß-carotene, curcumin, allicin, and sodium butyrate supplementation of laying breeder hen diets produced more advantages in growth performance and intestinal development in offspring than in chicks directly supplemented with antibiotics.

PURPOSE: X-linked hypophosphatemia (XLH) is the most common inherited renal phosphate wasting disorder and is often misdiagnosed as vitamin D deficiency. This study aims to provide clinical and mutational characteristics of 65 XLH pediatric patients in southern China. METHODS: In this work, a combination of DNA sequencing and qPCR analysis was used to study the PHEX gene in 80 pediatric patients diagnosed with hypophosphatemia. The clinical and laboratory data of confirmed 65 XLH patients were assessed and analyzed retrospectively. RESULTS: In 65 XLH patients from 61 families, 51 different variants in the PHEX gene were identified, including 23 previously reported variants and 28 novel variants. In this cohort of XLH patients, the c.1601C>T(p.Pro534Leu) variant appears more frequently. Fourteen uncommon XLH cases were described, including four boys with de novo mosaic variants, eight patients with large deletions and a pair of monozygotic twins. The clinical manifestations in this cohort are very similar to those previously reported. CONCLUSION: This study extends the mutational spectrum of the PHEX gene, which will contribute to accurate diagnosis. This study also suggests a supplementary qPCR or MLPA assay may be performed along with classical sequencing to confirm the gross insertion/deletion.

Beginning in December 2019, coronavirus disease 2019 (COVID-19), due to 2019-nCoV infection, emerged in Wuhan and spread rapidly throughout China and even worldwide. Employing combined therapy of modern medicine and traditional Chinese medicine has been proposed, in which Ma Xing Shi Gan Decoction (MXSGD) was recommended as a basic prescription and applied widely in the clinical treatment of COVID-19. We investigated the underlying mechanism of MXSGD in treating COVID-19 utilizing the approaches of integrating network pharmacology. A total of 97 active ingredients of MXSGD were screened out, and 169 targets were predicted. The protein-protein interaction network exhibited hub targets of MXSGD, such as Heat shock protein 90, RAC-alpha serine/threonine-protein kinase, Transcription factor AP-1, Mitogen-activated protein kinase 1, Cellular tumor antigen p53, Vascular endothelial growth factor A, and Tumour necrosis factor. Gene Ontology functional enrichment analysis demonstrated that the biological processes altered within the body after taking MXSGD were closely related to the regulation of such processes as the acute inflammatory response, chemokine production, vascular permeability, response to oxygen radicals, oxidative stress-induced apoptosis, T cell differentiation involved in the immune response, immunoglobulin secretion, and extracellular matrix disassembly. KEGG enrichment analysis indicated that the targets of MXSGD were significantly enriched in inflammation-related pathways, immunomodulation-related pathways, and viral infection-related pathways. The therapeutic mechanisms of MXSGD on COVID-19 may primarily involve the following effects: reducing inflammation, suppressing cytokine storm, protecting the pulmonary alveolar-capillary barrier, alleviating pulmonary edema, regulating the immune response, and decreasing fever.

OBJECTIVES: We explored the associations between depressive symptoms and supplemental calcium and vitamin D intake in older adults. DESIGN: This was a prospective cohort study. PARTICIPANTS: 8,527 older adults aged ≥60 years from Zhejiang Major Public Health Surveillance Program (ZPHS) without depressive symptoms at baseline survey. MEASUREMENTS: Participants were divided into non-supplementation, calcium (Ca), vitamin D, and calcium plus vitamin D (CaD) groups based on their supplemental intake during the past year. Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9). Binary logistic regression analyses were performed to examine the association between depressive symptoms and supplemental intake. RESULTS: When compared to the non-supplementation group, the Ca group exhibited a significant odds ratio (OR) of 0.731 (95% CI: 0.552-0.967, P=0.028). After adjusting for age, sex, and Ca food sources, the OR was even smaller for the CaD group (OR: 0.326; 95% CI: 0.119-0.889, P=0.029). Additionally, our results indicated that taking Ca supplements ≥4 days/week yielded a significant OR of 0.690 (95% CI: 0.492-0.968) after full adjustment. Taking CaD supplements ≥4 days/week yielded a significant OR of 0.282 (95% CI: 0.089-0.898) after adjusting for age, sex, and Ca food sources. CONCLUSIONS: Supplemental intake of Ca or CaD ≥4 days/week can decrease the risk of depressive symptoms in older adults, although CaD supplements may be more effective.

In the process of modern Western obstetrical knowledge being introduced into China, obstetrical works and textbooks translated from different countries in different period have played an important role.In early stages, most of these obstetrical works were translated from Europe and the United States, such as Fu Ying Xin Shuo and Tai Chan Ju Yao.After the First Sino-Japanese War of 1895, with the Chinese intellectuals setting off a wave of learning from Japan, the view that learning from Japan to improve medicine is more convenient than from Europe and the United States prevailed, so a large number of Japanese obstetrical works were introduced into China.In the late Qing and early the Republic of China, Ding Fubao's Ding Shi Yi Xue Cong Shu contained such obstetric monographs as Zhu Shi Chan Po Xu, Ren Shen Sheng Li Pian, Fen Mian Chan Ru Sheng Li Pian He Bian, and Chan Ke Xue Chu Bu.Zhu Shi Chan Po Xu written by Takenaka Seiken(), which was translated and published in 1908, is the first Chinese translation of Japanese obstetrical monograph in modern China. It contained such knowledge as anatomy, physiology, diagnosis, disease, medicine, surgery, and nutrition and played an important role in the dissemination of Western obstetrical knowledge.

Objective: To investigate the alterations of the volumes and 3D shapes of fifteen subcortical nucleus in patients with post-stroke depression (PSD) and to explore the pathogenesis regularity and mechanism of early PSD. Methods: From 2015 to 2017, a total of 28 patients with PSD and 18 stroke patients without depression (PSND), 13 patients with depression (De) and 11 cases of healthy volunteers (NC) were enrolled to perform 3.0 T high resolution MRI.Computer automatic segmentation and vertex analysis were used to segment and measure the volume of bilateral nucleus accumbens, caudate nucleus, putamen, globus pallidus, thalamus, hippocampus, mygdale and brainstem. Results: The volume of bilateral nucleus accumbens and bilateral thalamus, left pallidum were different among groups with statistical difference (P<0.05). The nucleus volume of the PSD group was (415±128) mm(3) (L-Nac)/(303±90) mm(3) (R-Nac), (7 590±867) mm(3) (L-Th)/(7 459±905) mm(3) (R-Th), (1 675±328) mm(3) (L-Pa), which was smaller than that of PSND group (433±100) mm(3) /(307±88) mm(3), (7 999±961) mm(3) /(7 753± 955) mm(3), (1 790±286) mm(3) and other groups.The nuclei with significantly statistical differences between inter-group were found in following: between PSD group and NC group, right accumbens and bilateral thalamus (P<0.01); between PSD group and De group, right accumbens and right thalamus (P<0.001), left accumbens, left pallidum and left thalamus (P<0.01); between PSND group and NC group, right accumbens (P<0.05); between PSND group and De group, right accumbens (P<0.001), left accumbens and right thalamus (P<0.05). Significant differences in morphology changes of nuclei (P<0.05) by F test mainly located on the top and tail of right accumbens, the anterior and middle body of right caudate nucleus, the most part of bilateral thalamus, the ventromedial body of bilateral hippocampus, the anterior and body of left caudate nucleus, especially in left thalamus. Conclusion: PSD has abnormal volume and morphological structure of subcortical nuclei, which supports the role of subcortical structures changes in the pathophysiology and pathogenesis of early PSD.

A number of clinical guidelines on nutrition therapy in cancer patients have been published by national and international societies; however, most of the reviewed data focused on gastrointestinal cancer or non-cancerous abdominal surgery. To collate the corresponding data for esophageal cancer (EC), a consensus panel was convened to aid specialists from different disciplines, who are involved in the clinical nutrition care of EC patients. The literature was searched using MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and the ISI Web of Knowledge. We searched for the best evidence pertaining to nutrition therapy in the case of EC. The panel summarized the findings in 3 sections of this consensus statement, based on which, after the diagnosis of EC, an initial distinction is made between the patients, as follows: (1) Assessment; (2) Therapy in patients with resectable disease; patients receiving chemotherapy or chemoradiotherapy prior to resection, and patients with unresectable disease, requiring chemoradiotherapy or palliative therapy; and (3) Formula. The resulting consensus statement reflects the opinions of a multidisciplinary group of experts, and a review of the current literature, and outlines the essential aspects of nutrition therapy in the case of EC. The statements are: Patients with EC are among one of the highest risk to have malnutrition. Patient generated suggestive global assessment is correlated with performance status and prognosis. Nutrition assessment for patients with EC at the diagnosis, prior to definitive therapy and change of treatment strategy are suggested and the timing interval can be two weeks during the treatment period, and one month while the patient is stable. Patients identified as high risk of malnutrition should be considered for preoperative nutritional support (tube feeding) for at least 7-10 days. Various routes for tube feedings are available after esophagectomy with similar nutrition support benefits. Limited intrathoracic anastomotic leakage postesophagectomy can be managed with intravenous antibiotics and self-expanding metal stent (SEMS) or jejunal tube. Enteral nutrition in patients receiving preoperative chemotherapy or chemoradiation provides benefits of maintaining weight, decreasing toxicity, and preventing treatment interruption. Tube feeding or SEMS can offer nutrition support in patients with unresectable esophageal cancer, but SEMS is not recommended for those with neoadjuvant chemoradiation before surgery. Enteral immunonutrition may preserve lean body mass and attenuates stress response after esophagectomy. Administration of glutamine may decrease the severity of chemotherapy induced mucositis. Enteral immunonutrition achieves greater nutrition status or maintains immune functions during concurrent chemoradiation.

In 1893, Wan Tsun-mo translated and published Tai chan ju yao (Essentials in Obstetrics), the first monograph of western obstetrics in modern China, symbolizing the independence of obstetrics from such maternal and child books as Fu ying xin shuo and Fu ke jing yun tu shuo, which occupies an important position in the history of the development of modern Chinese obstetrics. The book introduced anatomy, physiology, pathology, embryology, diagnostics, surgery, pharmacology and other knowledge of obstetrics in a catechismal form, and had a detailed discussion of such advanced obstetrical technologies as antiseptic, anesthesia, forceps and cesarean section for the first time.Judging from the content and translation of Tai chan ju yao, this book has already possessed the basic knowledge system of modern obstetrics, though the translation appeared to be somewhat jerky and not elegant and the terminology needing to be further improved, it was not only used as an important medium for the introduction of obstetrical knowledge, but also of great clinical value.However, its influence was so weak that later researchers seldom mentioned this book.

Objective: To investigate the impact of clinicopathological features, gene rearrangements and protein expression of bcl-6, bcl-2, C-MYC and chemotherapy regime on the prognosis of patients with primary central nervous system diffuse large B-cell lymphoma (PCNS-DLBCL). Methods: Thirty-three cases of PCNS-DLBCL diagnosed from January 2006 to December 2016 at Zhejiang Cancer Hospital were collected. The expression of CD10, bcl-6, bcl-2, MUM1 and MYC were detected by immunohistochemical staining (IHC). The presence of EB virus was detected by in situ hybridization(EBER). Copy number variation (ICN) and translocation status of bcl-6, bcl-2 and C-MYC genes were detected by fluorescence in situ hybridization (FISH). The relationship between the above indexes and the prognosis was analyzed by univariate, bivariate survival analysis and multiple Cox hazard regression analysis. Results: The study included 33 patients of PCNS-DLBCL, without evidence of primary or secondary immunodeficient disease. Male to female ratio was 1.36â¶1.00, and the average age was 56 years. Twenty cases had single lesion while 13 had multiple lesions. Deep brain involvement was seen in 12 cases. All patients underwent partial or total tumor resection. Five patients received whole brain post-surgery radiotherapy, nine patients received high-dose methotrexate (HD-MTX) based chemotherapy, and 12 patients received whole-brain radiotherapy combined with HD-MTX based chemotherapy. Severn patients received no further treatment and rituximab was used in 8 patients. According to the Hans model, 27 cases were classified as non-GCB subtypes (81.8%). Bcl-2 was positive in 25 cases (75.8%, 25/33) and highly expressed in 8 (24.2%). MYC was positive in 12 cases (36.4%) and double expression of bcl-2 and MYC was seen in 6 cases. EBER positive rate was 10.0%(3/30), all of which had multiple lesions. Two bcl-6 gene translocations and 3 amplifications were found in 28 patients. Two translocations, 3 ICN or with both bcl-2 gene translocation and ICN were found in 30 patients. Four ICNs of C-MYC gene were found in 28 patients. Elevated protein in cerebrospinal fluid (CSF) was found in 13 patients. LDH increased in 10 cases. Follow-up period was 2-90 months with the average survival time of (23.0±3.7) months and two-year survival rate of 39.0%. Univariate survival analysis showed that overexpression of bcl-2 protein (≥70%) and MYC protein (≥40%), bcl-2 gene abnormality (including copy number increase and translocation), C-MYC gene copy number increased were adverse factors for survival. C-MYC/ bcl-2 gene double hit was seen in 2 cases. Bivariate survival analysis found that of bcl-2/MYC protein double expression and bcl-2 and C-MYC genes double aberration were significantly associated with adverse outcomes. Cox multivariate risk regression analysis found that gender, cerebrospinal fluid protein increasing, and ICN of C-MYC gene were independent poor prognostic factors. DH-MTX based comprehensive chemotherapy was associated with better prognosis. Conclusions: Double hit at genomic level (copy number variations and gene rearrangements) and double protein expression of bcl-2 and C-MYC in PCNS-DLBCL are significantly associated with an adverse outcome. DH-MTX based comprehensive treatment may prolong the patient survival.

This retrospective study investigated the efficiency of nutritional support in unresectable locally advanced oesophageal squamous cell carcinoma (LAOSCC) patients who received concurrent chemoradiotherapy (CCRT) based on 5-fluorouracil and cisplatin. In the routine care group, 63 patients served as historical controls and received nutrition support in a reactive manner. In addition, 57 patients in the nutritional support group received timely diet counselling, oral nutritional supplements, enteral nutrition and/or parenteral nutrition during CCRT. This support was based on scores from nutritional risk screening 2002 (NRS-2002) after June 2014. The nutritional support group had significant advantages over the routine care group with respect to the incidence of neutropenia, the objective response rate, the change in serum albumin and the lengths of hospital stay. In addition, the nutritional support group had significantly higher levels of IgG and IL-2, higher proportions of NK, CD3+ and CD4+ cells as well as a higher ratio of CD4+ /CD8+ cells than the routine care group (p < .05). In contrast, the nutritional support group had a significantly lower level of IL-6. In conclusion, the current nutritional care programme could bring benefits of improving treatment compliance, reducing toxicity and lengths of hospital stay and enhancing the immune response.

BACKGROUND AND PURPOSE: Large-scale studies of utilization of medical services among patients with Alzheimer's disease (AD) are lacking. We aimed to investigate the usage of Western medicine and traditional Chinese medicine (TCM) among these patients in Taiwan. METHODS: We analyzed one million samples from the National Health Insurance Research Database in Taiwan. Patients (n = 1814) newly diagnosed with AD in 2001-2010 were divided into TCM users (n = 528) and non-TCM users (n = 1286). RESULTS: Compared with non-TCM users, TCM users were younger, had a higher female:male ratio and higher utilization rate of Western medicine. The median interval between diagnosis and the first TCM consultation was 7.92 months. Donepezil and rivastigmine were commonly prescribed medications. Chinese herbal medicine was the most popular treatment among TCM users. CONCLUSIONS: This study revealed the specific usage patterns of TCM and non-TCM medical services among patients with AD. The information could be used for improving the healthcare of patients with AD.

Guangming (GB37) gained its name before the writing of Huang di Ming Tang Jing (The Yellow Emperor's Mingtang Classic), the earliest work of the art of acupuncture point. However, in acupuncture and moxibustion works before the Song Dynasty, this acupoint was not used to treat eye diseases. In Dou Hanqing's Zhen jiu biao you fu (Song to Elucidate Mysteries in Acupuncture Moxibustion), Guangming was used to treat oculopathy as an alias of Cuanzhu (BL2). Influenced by this, the alias "Guangming" was mistaken as Guangming (GB37) of the Gallbladder Meridian in the Bian que shen ying zhen jiu yu long jing (Bian Que Acupuncture and Moxibustion Jade Dragon Classic) of the Yuan Dynasty, and the symptom of eye itch was added to the indications of Guangming (GB37). This was wrongly informed in the later acupuncture and moxibustion works, and the modern scholars also accepted it and confirmed its effect by the clinical and experimental research.

We investigated dynamic changes in T-lymphocyte subsets after hyperthermic intraperitoneal chemotherapy (HIPEC) or radiotherapy using flow cytometry. A total of 1423 lung cancer patients admitted to our hospital between October 2012 and July 2015 were enrolled, and age-matched healthy individuals served as controls. Peripheral blood mononuclear cells (PBMCs) were purified using standard Ficoll density gradient centrifugation, based on which CD3+, CD4+, and CD8+ T-cells were isolated. A surface marker was identified by flow cytometry. Immunohistochemical analysis determined the distribution of the cells in the tumor mass or adjacent tissues. A total of 957 patients (male: 555; female: 402; median age: 49.3 years) with lung cancer who had received only HIPEC or radiotherapy were enrolled. The patients were followed-up until death. No statistical difference was noticed between the patients who had received chemotherapy compared with the baseline levels. A remarkable elevation was noticed in the CD3+ T-cells in the patients three months after radiotherapy (78.71 ± 9.36 vs 68.15 ± 9.65, P < 0.05). The level of CD8+ in the patients who had received chemotherapy or radiotherapy was remarkably elevated in the post-treatment period (P < 0.05). The CD3+ and CD8+ T-cells were mainly expressed in the cytoplasm rather than in the adjacent tissues. The expression of CD3+ and CD4+ was correlated to tumor infiltration and metastasis. Remarkable elevation was noticed in the CD3+ T-cells in the patients three months after radiotherapy. The expression of CD3+ and CD4+ was negatively correlated to tumor infiltration and metastasis in non-small-cell lung cancer patients.

Magnetization transfer (MT) is a neuroimaging technique that is frequently used to characterize the biophysical abnormalities in both gray and white matter regions of the brain. In our study, we used MT to examine the integrity of key nodes in frontal-subcortical circuits in four subject groups: patients diagnosed with type 2 diabetes with and without major depression (MDD), a healthy control group, and a group diagnosed with MDD without diabetes. In the MDD group, MT studies demonstrated lower magnetization transfer ratios (MTR), a marker of abnormalities in the macromolecular protein pool, in the thalami when compared with the control groups. The group with diabetes and MDD showed lower MTR in the globus pallidus when compared with the group with MDD. Biophysical measures, in subcortical nuclei, correlated inversely with measures of glycemic control, cerebrovascular burden and depression scores. These findings have broad implications for the underlying neuronal circuitry and neurobiology of mood disorders.

Deoxynivalenol (DON) causes various toxic effects in human and animals. However, our previous studies have shown that composite antimicrobial peptides (CAP) can have a protective effect in piglets challenged with DON. This study was conducted to evaluate the effect of the CAP GLAM 180# on the metabolism of piglets challenged with DON using a nuclear magnetic resonance (NMR)-based metabolomics approach. A total of 28 individually housed piglets (Duroc × Landrace × Large Yorkshire) weaned at 28 d of age were randomly assigned into 4 treatment groups (7 pigs/treatment) based on a 2 × 2 factorial arrangement that were fed, respectively, a basal diet (NC), basal diet + 0.4% CAP (basal + CAP), basal diet + 4 mg/kg DON (basal + DON), and basal diet + 4 mg/kg DON + 0.4% CAP (DON + CAP). A 7-d adaptation period was followed by 30 d of treatment. Blood samples were then collected for metabolite analysis by proton NMR (H-NMR) spectroscopy and liquid chromatography tandem mass spectrometry (LC-MS/MS). The combined results of H-NMR spectroscopy and LC-MS/MS showed that DON increased ( < 0.05) the serum concentrations of low-density lipoprotein, glycoprotein, urea, trimethylamine-N-oxide (TMAO), and lactate as well as those of almost all essential AA and some nonessential AA but decreased the concentrations of high-density lipoprotein (HDL), unsaturated lipids, citrate, choline, and fumarate compared with those in NC treatment ( < 0.05). There was a significant interaction effect ( < 0.05) of supplementation with DON and CAP on some metabolites showed that the serum concentrations of HDL, unsaturated lipids, Pro, citrate, and fumarate were greater ( < 0.05) whereas those of glycoprotein, urea, TMAO, Gly, and lactate were lower in the DON + CAP treatment compared with those in the basal + DON treatment ( < 0.05). These findings indicated that DON causes disturbances in AA, lipid, and energy metabolism and that CAP could partially attenuate the above metabolic disturbances induced by DON.

Chronic Helicobacter pylori-stimulated immune reactions determine the pathogenesis of gastric mucosa-associated lymphoid tissue (MALT) lymphoma. We aimed to explore the genetic predisposition to this lymphoma and its clinical implication. A total of 68 patients and 140 unrelated controls were genotyped for 84 single-nucleotide polymorphisms in genes encoding cytokines, chemokines and related receptors that play important roles in T cell-mediated gastrointestinal immunity. Five genotypes in IL-22, namely CC at rs1179246, CC at rs2227485, AA at rs4913428, AA at rs1026788 and TT at rs7314777, were associated with disease susceptibility. The former four genotypes resided in the same linkage disequilibrium block (r(2)=0.99) that conferred an approximately threefold higher risk. In vitro experiments demonstrated that co-culturing peripheral mononuclear cells or CD4(+) T cells with H. pylori stimulated the secretion of interleukin-22 (IL-22), and that IL-22 induced the expression of antimicrobial proteins, RegIIIα and lipocalin-2, in gastric epithelial cells. Furthermore, patients with gastric tissue expressing IL-22 were more likely to respond to H. pylori eradication (14/22 vs 4/19, P<0.006). We conclude that susceptibility of gastric MALT lymphoma is influenced by genetic polymorphisms in IL-22, the product of which is involved in mucosal immunity against H. pylori and associated with tumor response to H. pylori eradication.

Traditional Chinese herbal therapies are widely used for the treatment of chronic hepatitis C (CHC) in China and several Asian countries. The aim of this study was to perform a meta-analysis of randomized controlled trials (RCTs) comparing peginterferon therapy with peginterferon plus Chinese herbal therapy for the treatment of CHC. The Cochrane Central Register of Controlled Trials, Medline, Science Citation Index, EMBASE, China National Knowledge Infrastructure, Wanfang Database, and China Biomedical Database were searched to identify RCTs that evaluated the virological response of CHC patients to peginterferon therapy and peginterferon plus Chinese herbal therapy. We statistically combined data using a fixed-effects meta-analysis according to the intention-to-treat principle. The literature search yielded 905 studies and nine RCTs composed of 858 patients matched the selection criteria. Overall, sustained virological response (SVR) was significantly higher in patients treated with peginterferon plus Chinese herbs than in patients treated with peginterferon alone (81 % vs. 64 %, respectively; odds ratio, 2.60; 95 % confidence interval: 1.325.14; p < 0.05). A combined therapy of peginterferon plus Chinese herbs was also superior to peginterferon therapy in achieving an early viral response (EVR, 80 % vs. 70 %, respectively), a viral response at week 24 of treatment (82 % vs. 73 %, respectively), and end-of-treatment viral response (ETVR, 73 % vs. 62 %, respectively). The combined therapy resulted in fewer relapses, fewer adverse events, and more rapid alanine transaminase normalization; however, both treatments yielded a similar rapid viral response (RVR, 53 % vs. 57 %, respectively). The current evidence suggests that combined therapy of peginterferon plus Chinese herbs yields a higher viral response and results in fewer relapses and fewer adverse events than peginterferon therapy alone.
