?AIM: To investigate NO levels in tears and anterior chamber inflammation after phacoemulsification and intraocular lens implantation with trabeculectomy through different operative incisions.?METHODS: Totally 49 patients ( 50 eyes ) with primary acute angle - closure glaucoma and cataract were randomly divided to single-incision group and double-incision group. Both were treated by phacoemulsification and intraocular lens implantation and trabeculectomy after routine IOP-lowering drugs treatment. Preoperative and postoperative NO levels in tears were compared, and the aqueous flare and cells were examined using a laser flare-cell meter ( LFCM) .?RESULTS:Postoperative tear NO was 9. 86±0. 78μmol/L in single-incision group , it was 9. 13 ± 0. 67μmol/L in double-incision group, the differences was statistically significant(t=3. 57,P<0. 05). Postoperative aqueous flare values was 62. 42±18. 16 pc/ms in single-incision group;it was 52. 20 ± 17. 57 pc/ms in double-incision group, the differences was statistically significant(t=2. 02, P<0. 05).?CONCLUSION: The early inflammatory injury of double-incision was significantly lower than that of single -incision. It has the advantages of safety. But the surgical skill should be improved to less the injuries caused by operations.

OBJECTIVETo evaluate the therapeutic effect of Liujunzi decoction combined with Zuojin pills in treating the radioactive duodenitis and their mechanism, and compare with clinical routine acid suppressants combined with mucous membrane protective preparations to study the mechanism of their efficacy.

METHODAccording to the study of Williams J P and characteristics of duodenitis, and by reference to the radiation enteritis modeling standard, we took the lead in establishing the mouse radioactive duodenal injury model. The model mice were randomly divided into the control group (n = 26), traditional Chinese medicine (TCM) group (n = 16) and the western medicine (oral administration with famotidine 0.5 mL + almagate suspension 0.3 mL per mouse, once a day) group (n = 16). After the standard administrating, such objective indexes as general condition, weight, changes in health score, pathology and expression of inflammatory factors were observed to evaluate the efficacy.

RESULTThe radioactive duodenitis model of mice was successfully established with 12 Gy. Mice in the control group suffered from weight loss, anorexia, low fluid intake, loose stools, and occasionally mucous bloody stool, poor spirit, dim fur, lack of exercise and arch back. Mice in drug intervention groups were generally better than those in the pure irradiation group. The IL-6, IL-1beta, TNF-alpha mRNA expressions in spleen and mesenteric lymph node tissues in TCM and western medicine groups showed a declining trend compared with the control group. Their concentrations in peripheral blood serum also slightly changed. The TCM group revealed notable advantage in reducing inflammatory factors. The microscopic observation showed that a better mucosa repair in intervention groups than the pure irradiation group. The improved Chiu's scoring method showed a statistical significance in the difference between TCM and western medicine groups (P < 0.05).

CONCLUSIONLiujunzi decoction combined with Zuojin pills could treat acute radiation enteritis, regulate organic immunity, and inhibit acute injury, promote local tissue repair, with the potential to resist such adverse effects as radiation intestinal fibrosis. The regulation of inflammatory factor release is one of efficacy generation mechanisms.

OBJECTIVETo explore the expression of human leucocyte antigen DR (HLA-DR) gene in peripheral blood mononuclear cells (PBMCs) of systemic lupus erythematosus (SLE) patients of various TCM syndrome types in order to seek an objective index for syndrome differentiation of SLE.

METHODSSLE patients were sorted into various syndrome types by TCM syndrome differentiation, i. e. Pi-Shen yang-deficiency type (A), yin-deficiency with internal heat type (B), qi-yin deficiency type (C) and Gan-Shen yin-deficiency type (D). Their peripheral blood sample was collected for detecting HLA-DR positive lymphocytes and monocytes in PBMC using flow cytometry.

RESULTSComparisons among patients of various syndrome type showed that the proportion of HLA-DR positive monocytes and lymphocytes in PBMC in patients of type A was the lowest (P < 0.01); proportion of HLA-DR positive lymphocytes in patients of type B was significantly higher than in those of type C and D (P < 0.01), and that in type D was higher than in type C (P < 0.05); total proportion of HLA-DR positive cells in patients of type A was the lowest, that in type B was higher than that in type C and D (P < 0.01, P < 0.05), while no significant difference was found between the latter two types (P > 0.05).

CONCLUSIONHLA-DR could be taken as an objective index for reference in syndrome differentiation of SLE.

OBJECTIVETo investigate the role of endoplasmic reticulum stress in the apoptosis of testicular germ cells in hyperlipidemic rats.

METHODSWe randomly assigned 42 four-week-old male Wistar rats into a normal control group (n = 12) and a high-fat group (n = 30) to be fed on a normal diet and a high-fat diet, respectively, for 10 weeks. Then we measured the concentrations of triglyceride (TG) and total cholesterol (TC) in the serum using an automatic biochemistry analyzer, detected the apoptosis of testicular germ cells by TUNEL staining, and determined the protein and mRNA expressions of GRP78 and. caspase-12 in the testis tissue by immunohistochemistry and RT-PCR, respectively.

RESULTSThe concentrations of TG and TC were significantly increased in the animals of the high-fat group ([3.00 ± 0.92] and [3.04 ± 0.39] mmol/L) as compared with the control rats ([1.43 ± 0.41] and [1.55 ± 0.23] mmol/L) (P < 0.01), and so was the apoptosis index of the testicular germ cells ([37.17 ± 2.74]% vs [5.16 ± 0.81]%, P < 0.01). The high-fat group, in comparison with the control, also showed remarkably upregulated protein and mRNA expressions of GRP78 (0.32 ± 0.03 and 0.86 ± 0.05 vs 0.19 ± 0.01 and 0.37 ± 0.03, P < 0.01) and caspase-12 (0.34 ± 0.02 and 0.87 ± 0.01 vs 0.12 ± 0.01 and 0.34 ± 0.03, P < 0.01) in the testis tissue.

CONCLUSIONThe apoptosis of testicular germ cells is increased in hyperlipidemic rats, which may be attributed to endoplasmic reticulum stress.

OBJECTIVETo explore effects of Shenqi preparation,Traditional Chinese Medicine, on anti-fatigue and anti-oxidant functions.

METHODSOne hundred and twenty mice were randomly divided into control group and 3 experimental groups. The high, medium and low-dose of Shenqi preparation were given to the 3 experimental groups respectively, while distilled water to the control group for 15 d. The loaded swimming time, the level of lactate, serum urea nitrogen (SUN), muscle and liver glycogen, liver super-oxide dismutase (SOD), the content of malondialdehyde (MDA), glutathione peroxidase(GSH-Px) were assayed.

RESULTSThe loaded swimming test showed that the exhausted swimming time of 3 experimental groups [(296.0 +/- 25.3)s, (437.0 ĝ 38.9)s, (595.0 +/- 53.9)s respectively] was longer than that of control group [(231.0 +/- 22.5)s, P < 0.05, P < 0.01]. The liver glycogen content of the high and medium-dose experimental groups were higher than that of control group respectively (P < 0.01). The SUN content of each experimental group was less than that of the control group (P < 0.01, P < 0.05). Moreover,in the medium and high dose experimental groups, less accumulation of lactate was found (P < 0.01, P < 0.05), and the content of liver SOD and GSH-Px was higher (P < 0.01, P < 0.05). The content of liver MDA in high-dose experimental group was less than that of the control group (P < 0.05).

CONCLUSIONShenqi preparation, especially the high and medium-dose experimental groups, is able to improve exercise tolerance and has anti-fatigue and anti-oxidant effects in mice.

Objective To deeply understand the risk factors of lymphedema for patients with breast cancer after surgery. Methods The phenomenological method was applied in this study. Semi-structured interview was used to collected data from 9 female breast cancer patients with lymphedema after surgery in our hospital from June to September 2016 for generic analysis. Results The risk factors of lymphedema could be categorized into four themes:(1)choice of treatment is the primary cause:axillary lymph node dissection; radiotherapy; chemotherapy; (2)not paying enough attention to lymphedema:lacking the knowledge of lymphedema; imbalance of physical activities for the affected limb; lacking awareness of exercise and protection of the affected limb. Conclusions Axillary lymph node dissection after radical surgery for patients with breast cancer is the primary cause of lymphedema, and paying not enough attention is an important factor, especially lacking the consciousness of prevention, so the nurses should emphasize education about prevention of lymphedema after surgery for patients, to improve the consciousness of them to reduce the occurrence of lymphedema and its influence on their quality of life.
