OBJECTIVETo study the effect of coixenolide on Foxp3+ CD4+ CD25+ regulatory T cells (Treg) in collagen induced arthritis (CIA) mice, and to explore its possible mechanism for treating rheumatiol arthritis.

METHODSFive mice were recruited as a normal control group from 25 mice, and the rest 20 were used in CIA modeling. After successful modeling they were randomly divided in the model control group and the coixenolide group, 10 in each group. Coixenolide injection at 25 mL/kg was intraperitoneally injected to mice in the coixenolide group, while normal saline at 25 mL/kg was intraperitoneally injected to mice in the normal control group and the model control group. The injection lasted for 21 days. Scoring for CIA was performed after injection and arthritis index was calculated. The peripheral blood Foxp3+ CD4+ CD25+ Treg ratio was determined by flow cytometry (FCM).

RESULTSCompared with the normal control group, the arthritis index obviously increased in the model control group (P < 0.01). The arthritis index obviously decreased more in the coixenolide group than in the model control group (P < 0.01). Foxp3+ CD4+ CD25+ Treg levels obviously decreased more in the model control group than in the normal control group (P < 0.01 ). Foxp3+ CD4+ CD25+ Treg levels obviously increased more in the coixenolide control group than in the model control group (P < 0.01).

CONCLUSIONCoixenolide could up-regulate Foxp3+ CD4+ CD25+ Treg ratios in CIA mice, which might play certain immunoregulation roles in the incidence of CIA.

The volatile components of roots and stems of Zanthoxylum nitidum were investigated by supercritical fluid carbon dioxide extraction (SFE-CO2) and gas chromatography-mass spectrometry(GC-MS). Thirty-one and fifty-one compounds were identified in the supercritical extracts from roots and stems of Z. nitidum, respectively, and total twenty-seven compounds were the common constituents. Among them, the major constituents in root and stem supercritical extracts were spathulenol (18.49 and 26.18%), n-hexadecanoic acid (14.24% and 12.79%), ar-tumerone (6.95% and 8.88%), oleic acid (8.39% and 5.71%) and hexanoic acid (4.39% and 7.78%). The in-vitro MTT assay showed that the volatile components of roots and stems of Z. nitidum did not exhibited any cytotoxic activity against human cancer Huh-7 and normal IEC-6 cells. These results indicated the same nature of the volatile constituents in the root and stem of Z. nitidum. This investigation may provide further evidence for expansion of medicinal parts of Z. nitidum.

OBJECTIVEThis study aims to evaluate the quality of life (QOL) of patients who underwent resection of oral cancer and reconstruction by free anierolateral thigh perforator flaps (ALTF).

METHODSA total of 32 patients with oral and maxillofacial malignancies who had undergone the resection of oral cancer and reconstruction by ALTF were retrospectively analyzed. At 12 months postoperatively, the QOL of these patients was assessed by using the 14-item oral health impact profile (OHIP-14) and the medical outcome study short form-36 (SF-36) questionnaires.

RESULTSA total of 32 questionnaires were collected. In SF-36, the highest scoring domains were bodily pain (78.58 ± 14.82), physical functioning (72.08 ± 27.86), and the role of physical (60.00 ± 42.63), whereas the lowest scoring domains were role-emotional (41.67 ± 39.62), followed by mental health (50.75 ± 13.07) and health transition (54.17 ± 21.75). In OHIP-14, the lowest scoring domains were social disability (34.50 ± 11.32) and handicap (36.04 ± 12.05), indicating the functional recovery was better; and the highest scoring domains were physical pain (73.50 ± 18.96) and psychological discomfort (60.17 ± 20.66), indicating the functional recovery was worse.

CONCLUSIONThe ALTF is an ideal selection for the reconstruction of oral defects after cancer resection. In using this flap, the basic social need of patients after surgery can be satisfied. Moreover, the appearance and the functions of chewing, deglutition, and speech can be restored in varying degrees. Thus, ALTF can improve the patients' QOL.

Objective To investigate the values of three-dimensional visualization technology in the diagnosis and surgical treatment of hepatic hemangioma. Methods Thirty two patients with hepatic hemangioma who had been hospitalized during the period from July 2010 to January 2014 in our hospital were scanned by 64-slice spiral computerized tomography (CT) before surgical treatment. Three-dimensional (3D) reconstruction based on the CT data was carried out to achieve dignosis and surgical planning. Assisted with the 3D model , we chose the best surgical procedure for liver resection, protecting the major blood vessels near hemangioma and retaining normal liver tissue as far as possible. Results The location, size and shape of hepatic hemangioma, vascular variation, and spatial relationship with intrahepatic vessel were shown factually by three-dimensional reconstruction. All the hemangiomas were preoperatively assessed to be resectable. The compliance rate for preoperative surgical planning to actual surgery was 100%. Under assistance of the 3D model during surgery , 14 patients received laparoscopic hepatectomy and 18 underwent hepatectomy. Pringle′s maneuver was applied in 18 patients , with blocking time of (15.32 ± 7.12) min and blood loss of (188.63 ± 66.37) mL. The postoperative complications included pleural effusion in 5 patients and incision infection in one patients. Conclusions Three-dimensional visualization technology for the individualized diagnosis and treatment of hepatic hemangioma helps reduce surgical trauma and incidence of postoperative complications.

This study was aimed to explore the characteristics of urine metabolomics among HIV/AIDS patients with spleen-lung qi-deficiency. H-NMR technique was combined with principal component analysis and cluster analysis in the comparison of urine metabolic products among 24 HIV/AIDS cases with spleen-lung qi-deficiency and 20 healthy control cases. The results showed that urine metabolic products of HIV/AIDS patients with spleen-lung qi-deficiency and healthy people by H-NMR technique detection and PLS-DA analysis can classify the outline of urine metabolites. There were about 20 variables in the difference between two groups. The speculated substances contained glycyl-L-leucine, L-valine, α-aminobutyric acid, methyl succinic acid, glycine propionyl, and etc. It was concluded that H-NMR technique was able to classify the outline of urine metabolites between HIV/AIDS cases with spleen-lung qi-deficiency and healthy people. Part of the potential existed characteristic markers contributed to the clinical diagnosis of traditional Chinese medicine (TCM) syndrome differentiation of AIDS. It had certain effect in its quantitative analysis.

Objective To study the clinical features of congenital glucose-galactose malabsorption (CGGM),and to improve the understanding of CGGM.Method Clinical manifestations and treatment process of one patient with CGGM in our hospital were retrospectively analyzed.From 1966 to 2016 May,Chinese medical database and PUBMED were searched using Malabsorption syndrome,dehydration,hypernatremia , diarrhea , newborn , carbohydrate metabolism ,andglucose/galactose malabsorption as key words.The clinical features of CGGM reported in literatures were summarized.Result The patient in our hospital was a full-term female infant naturally delivered.The onset of the disease was on the 9th day after birth,and the clinical manifestations included severe diarrhea,severe dehydration,hypernatremia,metabolic acidosis and malnutrition.After intravenous infusion and symptomatic treatment,dehydration,hypernatremia and metabolic acidosis were corrected.However,there was no improvement of diarrhea characterized with watery and acidic stools,and neither was weight gain.Glucose loading test was negative,and fructose loading test was positive.Diarrhea was improved markedly using diagnostic carbohydrate-free formula,so CGGM was diagnosed clinically.SLC5A1 homozygous IVS7-2 A ＞ G mutation was detected which confirmed the diagnosis of CGGM.With carbohydrate-free formula feeding,the body weight of the infant was increased.Followed up for 2 months now,her body length and body weight were at P25 and P22 on growth curve respectively,and no obvious neurological sequela was observed.Our literature review revealed 7 reports including 48 cases of CGGM children.Literature review showed that:most children with CGGM (79.2％) had the onset within 7 days of life;main clinical features included diarrhea (100％),dehydration (100％),and malnutrition (54.2％);22.9％ of patients with carbohydrate-free formula and 27.1％ with fructose matrix formula were fed well;no death was detected,77.1％ had normal weight gain,and 91.7％ had normal development of the nervous system.Conclusion CGGM is rare.The symptoms include severe watery and acidic stools with onset during neonatal period.CGGM is associated with severe complications such as hypertonic dehydration and hypernatremia.The diagnosis is established based upon typical clinical manifestations,sugar loading test and SLC5A1 gene detection.Carbohydrate-free formula feeding is effective.
