OBJECTIVETo evaluate the efficacy and safety of Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion for pancreatic cancer with liver metastases (PCLM).

METHODSWe retrospectively selected 292 patients with PCLM who were treated by Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion at Tianjin Medical University Cancer Hospital from January 2001 to December 2010. All patients were assigned to the Western medicine treatment group (157 cases) and the integrative medicine treatment group (135 cases). Patients in the Western medicine treatment group were treated with gemcitabine (GEM)-based chemotherapy, and partial of them received regional arterial perfusion. Those in the integrative medicine treatment group additionally took Chinese herbs of clearing heat and eliminating mass for at least 4 weeks. The median survival time (MST) , adverse reactions and the incidence of complications were observed.

RESULTSThere was no statistical significance in general data between the two groups (P > 0.05). There was statistical difference in MST between the two groups (4.8 months vs 5.5 months, P < 0.05). No death occurred during chemotherapy or regional arterial perfusion. All toxic or adverse reactions were tolerable.

CONCLUSIONChinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion was effective and safe, and it could be optimally selected as palliative therapy for PCLM.

OBJECTIVETo analyze the clinical features, diagnosis, treatment, and prognosis of epithelioid sarcoma (ES).

METHODSThe clinical data of 13 cases with epithelioid sarcoma in the Tianjin Medical University Cancer Institute and Hospital from March 1995 to December 2009 were collected and analyzed. There were 10 males and 3 females in the group, with an average age of 41.5 years (range: 13 to 68 years). Nine patients had classic ES and 4 had proximal-type ES. Surgery was the mainstay of treatment. After the operation, four patients received radiotherapy, five received chemotherapy, and one received chemoradiotherapy.

RESULTSOf the 13 cases, only 1 had multi-locus lesion. The average tumor size was (6.07 ± 1.34) cm. The lymph node involvement was found in 46.2% of the patients. Local and distant failure occurred in 50% and 30% patients, respectively. The most common site for dissemination was the lung. Four cases died within 3 years after initial operation. The 1-, 2-, 5-, 10-year overall survival rates of the 11 cases were 72.7%, 54.5%, 27.3% and 9.1%, respectively, with a median survival time of 27 months.

CONCLUSIONSEpithelioid sarcoma is a rare disease. The prognosis for patients with epithelioid sarcoma is poor because of a high propensity for local recurrence, lymph node metastases, and/or distant metastases. The definite diagnosis depends mainly on the pathologic examination. Wide surgical excision is the mainstay treatment, and radiation and chemotherapy have been used occasionally as adjuvant therapy but have had limited success.

·AIM:To determine the effect of anterior-posterior joint surgery on choroidal thickness in patients with proliferative diabetic retinopathy (PDR). · METHODS: A retrospective, case - control study enrolled 60 eyes of 60 patients with PDR diagnosed at Qingdao Municipal Hospital. The patients, who had conditions that warranted anterior - posterior joint surgery,were divided into a clinically significant macular edema group (PDR/CSME+;31 patients,31 eyes) and a non-CSME group (PDR/CSME-;29 patients,29 eyes). Twenty-seven eyes of 27 normal patients were included in the control group. All affected eyes underwent anterior - posterior joint surgery. After surgery, the subfoveal choroidal thickness (SFCT), and the nasal choroidal thickness (NCT) and temporal choroidal thickness (TCT), which were obtained at a distance of 1500μ m from the fovea in the nasal and temporal directions, respectively, were measured in the control and PDR groups by enhanced depth imaging spectral domain optical coherence tomography (EDI-SDOCT) at 1wk,1,3, and 6mo after surgery. Changes in choroidal thickness after anterior - posterior joint surgery were compared between the groups. ·RESULTS:The SFCT,NCT,and TCT were significantly thicker at 1mo than at 1wk, 3, and 6mo after surgery in the PDR/CSME+ and PDR/CSME- groups(P<0.05). The SFCT, NCT, and TCT were significantly thinner at 6mo than at 1wk,1,and 3mo after surgery in the PDR/CSME+and PDR/CSME- groups(P<0.05). The SFCT,NCT,and TCT in the PDR/CSME+ and PDR/CSME- groups at 1wk, 1, and 3mo after surgery were significantly thicker than those in the control group (all P<0.05), but the SFCT, NCT, and TCT at 6mo after surgery showed no significant difference compared with the control group (all P>0.05). There was no significant difference in the SFCT,NCT, or TCT at 1wk, 1, 3, or 6mo between the PDR/CSME+ and PDR/CSME- groups (P>0.05). ·CONCLUSION:The choroidal thickness of PDR patients increases within 1mo after surgery, and decreased after 1mo,but is not significantly different between the control group and the PDR groups at 6mo after surgery. Whether PDR is associated with CSME has no effect on the choroidal thickness after surgery.

We investigated the effects of fish protein hydrolysate (FPH) on growth performance and humoral immune response of the large yellow croaker (Pseudosciaena crocea R.). One thousand and two hundred large yellow croakers [initial average weight: (162.75+/-23.85) g] were divided into four groups and reared in floating sea cages (3 m x 3 m x 3 m). The animals were fed with 4 diets: basal diet only (control) or diets supplemented with 5%, 10% and 15% (w/w) FPH. The results show that dietary FPH levels significantly influenced the growth and immunity of the large yellow croaker. Compared with the control group, total weight gain (TWG) in all treatment groups, relative weight gain (RWG) and specific growth rate (SGR) in fish fed with diets supplemented with 10% and 15% FPH were significantly increased (P<0.05). Similar results were observed in immune parameters [lysozyme activity, serum complements, immunoglobulin M (IgM)]. Lysozyme activity, complement C4 and IgM were also significantly increased (P<0.05) in fish fed with diets supplemented with 10% and 15% FPH, while complement C3 level was significantly increased (P<0.05) in all treatment groups. In general, with the supplementation of FPH, particularly at dose of 10%, the growth performance and immunity of the large yellow croaker can be improved effectively.

Human cytomegalovirus glycoprotein complex Ⅱ (gC Ⅱ ) consists of two glycoproteins, gM and gN. Although gC Ⅱ specific IgG purified from HCMV positive patient sera can neutralize HCMV, there has been no report on the generation of virus-neutralizing antibodies by immunizing with one epitope of gM. The epitope, termed MAD, was screened from random phage peptide library by subtractive strategy. The peptide sequence of MAD was highly homologous with 32~38 amino acids of HCMV gM. Mice immunized with MAD coupled with keyhole limpet hemocyanin (KLH) could produce specific antibodies against MAD, and the antibodies obtained could bind not only native HCMV particles, but also the recombinant gM30～78 peptide. ELISA analysis results showed that MAD could specifically bind HCMV-positive human serum samples. Virus-neutralizing assay results demonstrated that the antibodies against MAD could inhibit HCMV strain AD169 entering the human embryonic lung cells. The results suggested that MAD could be used as a new potential protective antigen in the development of HCMV vaccine.

Contagious ecthyma (also known as orf) is an acute skin zoonosis caused by orf virus (ORFV), which affects sheep, goats and humans. As one of the typical species of the Parapoxvirus genus of the Poxviridae family, orf virus has distinctive and unique characteristics of these species. A range of immuno-modulatory/pathogenesis -related genes acquired by virus that function is to limit (at least transiently) the effectiveness of host immunity during its evolution. This review is aimed to describe the latest progress on the molecular characteristics of ORFV, and upon which we analyzed molecular mechanism of the immune escape designed and a set of strategies developed for ORFV to effective against immune clearance of the host. Known as an essential component in evolutionary system, host is regulated by ORFV for using in population evolution. By the ORFV evolutional immune regulation components and its effect approach, we can understand the viral biological characteristics of ORFV, and it is helpful for us to further study the counter-measures of this disease.

BACKGROUNDThe most significant biological change in intervertebral disc degeneration is the decrease of chondrocyte specific gene and protein expression of Sox9 and collagen type II. Interleukin-1 (IL-1) is not expressed in the normal intervertebral disc tissue but increases in the degenerated intervertebral disc tissue. This suggests that IL-1 may play a role in regulation of the expression of Sox9 and collagen type II.

METHODSHuman intervertebral disc cells were isolated and cultured. Sox9 and collagen type II expression during treatment with IL-1, with or without the nuclear factor-kappaB (NF-kappaB) activity inhibitor curcumin, were detected by using reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting, and the activity of the NF-kappaB signaling pathway was detected by the electrophoretic mobility shift assay (EMSA).

RESULTSIL-1 lowered the mRNA level and protein expression of Sox9 and collagen type II in the cultured intervertebral disc cells in a dose dependent manner (P < 0.05), and this effect was attenuated by curcumin. Curcumin alone had no effect on Sox9 and collagen type II expression (P > 0.05). IL-1 at concentrations of 0.1 ng/ml, 1 ng/ml and 10 ng/ml could stimulate the activity of NF-kappaB in the intervertebral disc cells in a dose dependent manner (P < 0.05) that was inhibited by curcumin.

CONCLUSIONSWe demonstrated the previously unknown function of IL-1 in inhibiting Sox9 and collagen type II via NF-kappaB in the intervertebral disc cells. This inhibition can be attenuated by curcumin, which is an effective NF-kappaB activity inhibitor.
