OBJECTIVETo study the expression levels of monokine induced by interferon-gama; (Mig) mRNA and its association with HBV DNA and alanine aminotransferase (ALT) in patients with chronic hepatitis B.

METHODSThe level of Mig mRNA in peripheral blood mononuclear cells (PBMCs) was dynamically detected with real-time quantitative PCR, and the ratio of chemokine/GAPDH was considered to represent the final chemokine level. The plasma level of was measured by enzyme-linked immunosorbent assay (ELISA).

RESULTSThe mean level of Mig mRNA in PBMCs of the patients with chronic hepatitis B was 0.6883-/+0.0693, which was significantly higher than that in normal controls (P<0.001). The plasma Mig level in the patients was 609.6-/+73.8 pg/ml, also significantly higher than that in normal controls (P<0.05). In patients with chronic hepatitis B, the level of Mig mRNA in the PBMCs was significantly correlated with plasma Mig level (r=0.7157, P<0.001), and plasma Mig level was correlated with plasma ALT level (r=0.7220, P<0.001) and plasma HBV DNA level (r=0.7266, P<0.001).

CONCLUSIONBoth the expression of Mig mRNA in PBMCs and plasma Mig concentration are elevated in patients with chronic hepatitis B. Mig plays an important role in migration of the inflammatory cells to the liver and mediates the development of chronic hepatitis B.

Objective To investigate the effect of laparoscopic totally extraperitoneal (TEP) on sexual function in young and middle-aged patients with inguinal hernia. Methods 147 male with inguinal hernia treated by TEP from January 2014 to Feberary 2016 were included in the observation group, while 133 male with inguinal hernia treated by laparoscopic transabdominal preperitoneal (TAPP) during the same time were included in the control group. The effect of surgery and changes on sexual function between the two groups were retrospective analyzed and compared. Results The operative time, length of hospital stay, time of postoperative pain and in the observation group shorter than in the control group. The differences between the two groups were statistically significant (P < 0.05). The level of seminal alpha glucosidase, fructose contents and acid phosphatase in the observation group were higher than in the control group at 12 months after surgery. The differences between the two groups were statistically significant (P < 0.05). There were a small number of complications in both groups. After symptomatic treatment, all complications were cured. The ratio of complications and recurrences of the two groups have no significantly differences (P > 0.05). Conclusion Compared with laparoscopic TAPP, laparoscopic TEP can shorten the time of postoperative recovery, and will not increase the complications and recurrences. It is good for recovery of semen quality. It is worthy of attention.

OBJECTIVETo investigate the tumor inhibition effect of Yangfei Kongliu Formula (YKF), a compound Chinese herbal medicine, combined with cisplatin (DDP) and its action mechanisms.

METHODSC57BL/6 mice with Lewis lung carcinoma were divided into six groups: control group (C), DDP group (2 mg/kg, DDP), low-dose YKF group (2.43 g/kg, L), high-dose YKF group (24.3 g/kg, H), low-dose YKF combined with DDP group (L + DDP) and high-dose YKF combined with DDP group (H + DDP). Transforming growth factor-β1 (TGF-β1), mothers against decapentaplegic homolog 3 (Smad3) and Smad7 levels were measured with quantitative real-time polymerase chain reaction (qPCR), Western blotting and immunohistochemistry. An enzyme-linked immunosorbent assay was used to analyze the expressions of interleukin-2 (IL-2) and tumor necrosis factor-α (TNF-α).

RESULTSYKF combined with DDP significantly inhibited the growth and metastasis of tumors relative to the control group, and YKF groups (P < 0.05). There was no significant difference between high-dose YKF group and low-dose YKF group (P > 0.05). We also found that the expression levels of TGF-β1 and Smad3 were both significantly decreased by YKF relative to the control group (P < 0.05). Furthermore, after treatment with YKF combined with DDP, the expression levels of TGF-β1 and Smad3 were decreased but the expression level of Smad7 was increased relative to the DDP group (P < 0.05). Compared to the DDP group, the combination of YKF and DDP enhanced the effect of tumor inhibition (P < 0.05), showing obvious synergy between YKF and DDP. Treatment with DDP or YKF decreased serum levels of IL-2 and TNF-α relative to the control group (P < 0.05). Furthermore, the expression levels of IL-2 and TNF-α were significantly decreased when treated with YKF in combination with DDP. Co-treatment with YKF and DDP significantly inhibited tumor growth, decreased the expressions of TGF-β1, Smad3, IL-2 and TNF-α and increased the expression of Smad7; these differences were significant relative to both YKF groups and the control group (P < 0.05).

CONCLUSIONYKF can inhibit tumor growth synergistically with DDP, mainly through the TGF-β1 signaling pathway.
