Objective To explore the relationship between immune functions of patients with acute leukemia (AL) and invasive fungat infection (IFI). Methods T lymphocyte subpopulations and natural killer (NK) cells in 61 AL patients complicated with IFI at first visit, AL remission, the time of IFI onset and 4 weeks after antifungal treatment were measured by flow cytometry. Meanwhile,levels of IgG, IgM and IgA were detected by immunoturbidimetry. The statistical analysis was done using ANOVA, t test and chi-square test. Results CD3+ , CD3+ CD4+ , CD8+ CD28+ T lymphocyte as well as CD4+/CD8+ ratio at the time of IFI onset in AL patients were all lower than those at first visit, AL remission and 4 weeks after antifungal treatment (F= 25.6,26.6,13. 1,167.9; all P＜0.05), while CD8+ CD28- T lymphocyte were higher than those at first visit, AL remission and 4 weeks after antifungal treatment (F= 220.2,P＜0.01). CD3+ , CD3+ CD4+ and CD4 + /CD8+ ratio of patients who responded effectively to antifungal treatment were all higher than those of non-responders (t=3.75,8. 61,3.17; all P＜0.05). The serum levels of IgG, Igm and IgA at first visit, ALremission, the time of IFI onset and 4 weeks after treatment were similar (F=0.78,0.72,0.81; all P ＞0.05). The effect rate of antifungal therapy in AL remission group was higher than that in nonremission group (87% vs 53%,x2 = 7.62, P＜0.05). Conclusions The cellular immune functions are impaired severely in AL patients complicated with IFI, while the levels of IgG, IgM and IgA are similar during IFI. Therefore, the efficacy of antifungal therapy may partly depend on the recovery of cellular immune functions and remission of AL.

OBJECTIVETo discuss the operation method and characteristic of correcting upper eyelid depression by transposition of orbital septum fat.

METHODSDuring the double eyelid surgery, we set.the lateral orbital septum fat completely free, while the bottom is still connected with the middle orbital septum fat. We separate a tunnel from the middle to the inner side in orbital septum, and the separated orbital septum fat is transposed to the inner side of orbital septum by the tunnel with suturing fixation.

RESULTSFrom March 2008 to October 2013, 51 cases with upper eyelid depression were treated successfully. Patients were followed up for 3 months to 3 years (average, 7. 5 months) with sustained aesthetic results.

CONCLUSIONSOrbital septum fat transposition can successfully correct the upper eyelid depression. It should become a regular procedure in blepharoplasty.

The effects of amino acid electuary (Ganan Elemental Granules) on experimental acute hepatic failure induced by D-galactosamine in rats were studied. The results showed that the electuary could significantly prevent the decrease in body weight and food intake, the prolongation in time of blood coagulation time and increase in the levels of serum glutamic-pyruvic transaminase activity, elevate contents of total serum protein and serum albumin, normalize the serum ratio of BCAA to AAA and disordered amino acid pattern, increase survival of animals and improve encephalopathy in rats with acute hepatic failure. These results suggest that the amino acid electuary has a better protective effects on acute hepatic failure.

The epitope-G1 gene of Bovine ephemeral fever virus (BEFV) glycoprotein was synthesised by PCR and cloned into expression vector pPIC9K to construct recombinant plasmid pPIC9K-G1. Then the pPIC9K-G1 was linearized and transformed into Pichia pastoris GS 115. The recombinant P. pastoris strains were selected by a G418 transformation screen and confirmed by PCR. After being induced with methanol, an expressed protein with 26 kDa molecular weight was obtained, which was much bigger than the predicted size (15.54 kDa). Deglycosylation analysis indicated the recombinant G1 was glycosylated. Western blot and ELISA tests, as well as rabbit immunization and specificity experiments indicated that the target protein had both higher reaction activity and higher immunocompetence and specificity. The recombinant G1 protein could be used as a coating antigen to develop an ELISA kit for bovine ephemeral fever diagnosis.

OBJECTIVETo observe the changes of the mechanical pain threshold in the rat model of autoimmune prostatitis, explore the mechanism of autoimmune prostatitis pain and offer some animal experimental evidence for the drug therapy of the condition.

METHODSTwenty male Wistar rats weighing 180 - 220 g were divided into a model and a control group. The autoimmune prostatitis model was established by subcutaneous injection of an extract of male rat prostate glands (RPG) at 60 mg/ml in Freund's complete adjuvant (FCA) and pertussis-diphtheria-tetanus vaccine at 0 and 30 days, respectively. Mechanical tactile hyperalgesia was measured once a week using Von Frey Filaments from the beginning of the study. At 8 weeks after modeling, the rats were sacrificed and the prostate tissues harvested for observation of histomorphological changes by HE staining.

RESULTSHE staining revealed different degrees of benign prostatitis in the model rats. Compared with the controls, the mechanical pain threshold in the model rats was significantly decreased with the increased time of modeling, from (65.52 +/- 6.27) g at 0 week to (23.67 +/- 4.09) g at 8 weeks (P < 0.01). Statistically significant differences were found in the variation trend at different time points between the two groups (P < 0.01).

CONCLUSIONAutoimmune prostatitis models were successfully established in rats and hyperalgesia was induced after modeling.

OBJECTIVETo demonstrate the expression of proteolysis induce factor(PIF) in the gastrointestinal(GI) cancer cachexia patients and evaluate its role in cancer cachexia.

METHODSExamination of PIF was performed in urine samples from 28 GI cancer cachexia patients, 13 GI cancer patients without cachexia, and 12 weight loss patients with benign disease. PIF was added to the mice cultured C2C12 muscle cells, then the protein kinase B(Akt) phosphorylation and morphological change were measured.

RESULTSThe positive rate of PIF in urine of 28 cancer cachexia patients was 53.6%(15/28). In the other two groups, no positive result was detected. PIF could successfully induce Akt phosphorylation, cell atrophy, metamorphosis, and death. The peak of this phosphorylation could be detected after half an hour of the initiation of PIF at a concentration of 4 nmol/L.

CONCLUSIONSPIF is specifically and highly expressed in GI cancer cachexia patients' urine. PIF can induce cancer cachexia possibly by activating Akt phosphorylation and inducing downstream proteolysis.

Objective To review the surgical managements of patients with traumatic false aneu- rysms in the extremities.Methods From January 1990 to April 2006,17 patients with traumatic false aneurysms in the extremities were admitted into our hospital.Fourteen patients were treated by vascular repair including vascular repair in seven cases,end to end anastomosis in one,synthetic grafting in one, autogenous vein grafting in one,and direct ligation in four.Three patients were treated nonoperatively, but with local compressive dressing.Results There were no deaths or gangrenes in all cases.The clinical manifestations vanished after the treatment.The mean follow-up period was 13.2 months.The function of the injured extremities recovered satisfactorily.Conclusion Different types of traumatic false aneurysms should be managed by different therapeutic procedures after the diagnoses is made.

OBJECTIVE To investigate the hospital infection rate and sites of patients in emergency intensive care(unit)(EICU),and provide basis for prevention and treatment of hospital infection.METHODS Patients who were hospitalized in EICU were investigated by retrospective study.RESULTS Among the hospital infection sites,(respiratory) tract was the most frequent one(65.63%),the next was urinary tract(28.13%),and the deep vein was the third(6.25%).The most common hospital infection bacteria were Staphylococcus aureus,Pseudomonas aeruginosa and Acinetobacter baumannii.CONCLUSIONS The analysis of the subjective and objective factors of hospital infection,and the acknowledge of relationship between nursing and hospital infection sites are(important) basis for hospital infection prevention and treatment.

This study is to investigate the antitumor activity of ophiopogonin B (OP-B). MTT assay, flow cytometric analysis, acridine orange staining, Lyso-Tracker Red staining and HeLa-GFP-LC3 transfect cells assay were used to detect the proliferation activity, apoptosis and autophagy of HeLa cells. The results showed that OP-B exerted potent antiproliferative activity on HeLa cells, the cell growth inhibition effect of OP-B was not due to apoptosis and OP-B could induce autophagy of HeLa cells. OP-B also induced the protein expression up-regulation of Beclin-1 and promoted LC3 I transformation LC3 II, which were representative proteins of autophagy. Furthermore, 3-MA, an inhibitor of autophagy, not only inhibited OP-B-mediated autophagy but also almost completely reversed the antiproliferative effect of OP-B, suggesting that the growth inhibition effect of OP-B was autophagy dependent. Western blotting demonstrated that OP-B inhibited the phosphorylation of Akt and its' downstream vital protein, such as mTOR and p70S6K. In addition, OP-B also induced the protein expression up-regulation of PTEN, which is a negative regulation protein for Akt/mTOR signaling pathway. However, OP-B did not affect the protein expression of total Akt. Collectively, the antitumor effects of OP-B were autophagy-dependent via repression Akt/mTOR signaling pathway. Therefore, OP-B is a prospective inhibitor of Akt/mTOR and may be used as an alternative compound to treat cervical carcinoma.
