Objective To investigate the expression of marray serine proteinase inhibitor(Maspin)in patients with oral squamous cell carcinoma and its relationship with clinicopathological features.Methods The Maspin protein expression was examined in 45 patients with oral squamous cell carcinoma and in non malignant oral epithelia by immunohistochemical staining.The relationship between the Maspin protein expression and the clinicopathological parameters was statistically analyzed. Results The Maspin protein expression in the cancerous tissues of oral squamous cell carcinoma was lower than that in the non-malignant oral epithelia(P=0.001). Negative correlation was found between the Maspin protein expression in cancerous tissue and the status of lymph node metastasis(P=0.038).Positive Maspin protein expression indicated negative lymph node metastasis,and negative correlation was also found between the Maspin protein expression and the postoperative metastasis(P=0.004).Positive correlation was found between the Maspin expression and the patients'survival rate(P=0.014),patients with positive Maspin protein expression having hisher survival rate than those with negative Maspin expression.Conclusions Maspin might be useful as a potential prognostic marker for oral squamous cell carcinoma.

This study was aimed to investigate the expression of blood Th17 and CD4(+) CD25(+) regulatory T cells (Treg) in the patients with aplastic anemia (AA). Forty-five patients with AA were enrolled into this study, and were divided into mild aplastic anemia (MAA) group (n = 25) and severe aplastic anemia group (SAA) (n = 20), blood cell count was recorded. 15 healthy donors were enrolled as control. Proportions of blood Th17 and CD4(+) CD25(+) Treg cells were determined by flow cytometry. The serum levels of IL-17, IFN-γ and TNF-α, as well as their concentrations in culture supernatant of phytohemagglutinin (PHA) -stimulated peripheral blood mononuclear cells, were measured by ELISA. The results showed that the proportions of blood Th17 cells and concentration of blood serum IL-17 and IFN-γ increased in patients with SAA, compared with MAA and normal controls, but CD4(+) CD25(+) Foxp3(+) Treg cells obviously decreased in patients with SAA. The concentrations of IL-17 and IFN-γ significantly increased in culture supernatant of SAA group. Hemoglobin level in the patients with AA negatively correlated with the population of Th17 cells and serum IL-17 level, whereas positively correlated with the expression of CD4(+) CD25(+)Treg cells. It is concluded that the increased response of Th17 cells and deficiency of CD4(+) CD25(+) Treg cells present in severe aplastic anemia. The severity of anemia may be related with the imbalance between Th17 and CD4(+) CD25(+)Treg cell response.

OBJECTIVETo investigate the effects of activated AKT on murine myeloid precursor cells (32D cells), and the effects of IFN-γ on 32D cells and its mechanisms.
METHODSPlasmid transduction was used to enhance the expression of AKT on 32D cells. After the transfected cells treated with IFN-γ for 24 hours, proliferation rate was tested by WST-1, apoptosis by flow cytometry, expression of phosphorylated Erk1/2, Stat3 and phosphorylated Stat3 was determined by Western blot.
RESULTS(1) IFN-γ at low concentration (100 U/ml) enhanced the growth and proliferation of 32D cells, while at high concentration (1000 U/ml) suppressed them. (2) Compared with control groups, low concentration IFN-γ increased (1124 ± 13) Stat3 phosphorylation in 32D-cell, while it high concentration IFN-γ decreased (601 ± 13). 32D cells transfected with activated Akt grew rapidly (0.287 ± 0.010) and had a low apoptotic rate [(9.57 ± 0.17)% (P < 0.05)]. (3) The expression of p-Erk1/2 in transfected 32D-cell was significantly reduced (P < 0.05). (4) Apoptosis rate of IFN-γ treated group was significantly decreased in transfected 32D cells (P < 0.05).
CONCLUSIONSIFN-γ has dual effects on 32D cells, namely, at low concentration enhanced the growth and proliferation of 32D cells, while at high concentration suppressed them. Its mechanisims is possibly through Stat3 pathway. Activated Akt can significantly promote the growth and proliferation of 32D cell and significantly inhibit apoptosis and IFN-γ can regulate cell proliferation and apoptosis through AKT. AKT activation can inhibit the Erk signal pathway, which may be affected by inhibition the modificaton of Raf1.

Objective The treatment methods for blood blister-like aneurysm remain controversial due to its special patholog-ical structure,the risk of post-operative rebleeding and the high rate of recurrence. The arm of this paper is to access the feasibility and effectiveness of overlapping stent-assisted coiling in the treatment of blood blister-like aneurysms of the internal carotid artery. Methods Form January 2014 to December 2016,we treated 15 patients with blood blister-like aneurysm of the internal carotid artery by stent-assisted coiling in the Department of Neurosurgery,5 with two Enterprise tents,3 with three Enterprise tents,4 with Enter-prise+LVIS tents,and 3 with two LVIS tents. We determined the rate of immediate embolization of aneurysms by Raymond-Roy Occlu-sion Classification(RROC)and analyzed the clinical characteristics,postoperative complications,and follow-up data. Results All the coils and stents were successfully implanted. RROC showed 9 cases of gradeⅠ(60%),4 cases of gradeⅡ(27%),and 2 cases of gradeⅢimmediate occlusion(13%),with the parent arteries unobstructed in all the cases. Thrombosis in the stent was found in 2 cases intraoperatively,slight stent migration in 1 case,and internal carotid artery dissection in the petrous segment in another,but no cer-ebral vasospasm or aneurysm rupture in any case.Delayed cerebral in-farct was observed in 2 cases postoperatively. The patients were fol-lowed up for 2 weeks to 28 months,which showed that 11 of them were cured,2 remained stable and 2 developed further thrombosis,with an MRS score of 0-2 in 12 cases,4 in 1 case,5 in 1 case, and 6 in 1case. Conclusion Overlapping stent-assisted coiling is effective for the treatment of blood blister-like aneurysm by reduc-ing the risks of rebleeding and recurrence.

Aim To explore the effect and mechanism of the artesunate(ART)on hepatocellular carcinoma(HCC).Methods The cell lines MHCC-97H and HCC-LM3 were used to be detected.MTT and clone formation were used to determine the cell proliferation;Wound healing was used to detect the cell migration;Transwell was used to test the cell invasion.Flow-cy-tometry was used to detect cell apoptosis and cell cy-cle.RNA-seq and qRT-PCR was used to detect the genes expression.Results The proliferation,migra-tion and invasion of treated cells were obviously inhibi-ted(P<0.01).Moreover,the apoptosis rate in-creased significantly,so did the proportion of G2/M cells.Transcriptomic analysis identified GADD45A as a potential target of ART through RNA-sequencing da-ta,and suggested that ART might induce apoptosis and cell cycle arrest through regulating the expression of GADD45A.In addition,the results of mechanism studies and signaling analysis suggested that GADD45A had interaction with its upstream gene NACC1(nucle-us accumbens associated 1).Moreover,after ART treatment,the expressions of GADD45A and NACC1 were changed significantly.Conclusion ART may be a potential drug to resist HCC by affecting the expres-sion of GADD45A and its upstream gene NACC1,which provides a new drug,a new direction and a new method for the clinical treatment of HCC.

OBJECTIVE:
To observe the effect of navel acupuncture on bladder emptying function in patients with urinary retention after stroke based on the conventional treatment.
METHODS:
A total of 106 patients with urinary retention after stroke were randomly divided into an observation group (53 cases, 3 cases dropped off) and a control group (53 cases, 3 cases dropped off). Patients in the control group were treated with drugs, catheterization and bladder function rehabilitation training. On the basis of the treatment in the control group, the observation group was treated with navel acupuncture, 30 min each time, once every other day, for 4 weeks. The bladder residual urine volume, spontaneous urination volume and catheterization times before and after treatment were compared between the two groups, and the clinical efficacy was evaluated.
RESULTS:
After treatment, in the two groups, the bladder residual urine volume and catheterization times were lower than those before treatment (P<0.01), and the spontaneous urination volume was higher than that before treatment (P<0.01); the bladder residual urine volume and catheterization times in the observation group were less than those in the control group (P<0.05, P<0.01), and the spontaneous urination volume was higher than that in the control group (P<0.01). The effective rate of the observation group was 90.0 % (45/50), which was higher than 72.0 % (36/50) in the control group (P<0.05).
CONCLUSION
On the basis of conventional treatment, navel acupuncture can effectively improve the bladder emptying function of patients with urinary retention after stroke.

This study was purposed to investigate the expression of miR-16 in T lymphoblastic lymphoma/acute lymphoblastic leukemia (T-LBL/ALL) and its relation with target therapy and prognosis. The CD3, cCD3, CD10, CD20, CD34, CD43, CD99, TdT, PAX-5, BCL-2 and Ki67 in paraffin samples from 38 cases of T-LBL/ALL were detected by immunohistochemical labeling; the miR-16 expression level was detected by real-time RT-PCR. Fifteen cases of reactive hyperplasia of lymph nodes were selected as control. The results indicated that among 38 cases of T-LBL/ALL the positive rate of TdT was highest (94.7%), the positive rate of CD34 was lowest (22.1%), the PAX-5 and CD20 were found to be negative. The Ki67 expression level in 39.5% cases exceeded 80%. As compared with reactive hyperplasia of lymph node, the miR-16 expression in T-LBL/ALL was up-regulated, ant its expression level was 4.87-fold of reactive hyperplasia of lymph node (P < 0.05). The overall survival rate in group of miR-16 high expression decreased (P < 0.05). The prognosis of T-LBL/ALL patients with BCL-2 positive expression was better than that of patients with BCL-2 negative expression (P < 0.05). The miR-16 expression correlated with BCL-2 protein (r = 0.51, P < 0.05). It is concluded that the overall survival rate in miR-16 high expression group is higher than that in miR-16 low expression group, suggesting possible relation of miR-16 with prognosis. Moreover, the prognosis in BCL-2 positive expression group is better than that in negative expression group, which may be a factor influencing prognosis.
