Objective To investigate the regulatory effects of hedgehog pathway on intestinal epithelial barrier function under hypoxia.Methods The IEC-6 cells of rats were divided into 3 groups:the normoxia group (21％ oxygen concentration),the hypoxia group (2％ oxygen concentration) and the hypoxia + cyclopamine group (cells pretreated by 5 mmol/L of cyclopamine,and then exposed in an atmosphere with 2％ oxygen concentration).The mRNA expressions of IHH,PTCH and GLI-1 were detected,and the transepithelial electrical resistance (TER) was determined.The protein expressions of tight junction proteins (ZO-1,Occludin,Claudin-1) and IHH were assayed by using the Western blot.All data were analyzed using the one-way analysis of variance or LSD-t test.Results The relative mRNA expressions of IHH,PTCH and GLI-1 were 0.056 ± 0.009,0.459 ± 0.087,0.142 ± 0.023 in the normoxia group,and 0.303 ± 0.052,0.678 ± 0.073,0.483 ± 0.061 in the hypoxia group,with significant difference between the 2 groups (t =-14.05,-11.85,-6.52,P ＜ 0.05).The relative protein expressions of IHH in the normoxia group and the hypoxia group were 0.39 ±0.06 and 0.91 ±0.15,with a significant difference between the 2 groups (t =-8.08,P ＜ 0.05).The TERs of the normoxia group,the hypoxia group and the hypoxia + cyclopamine group were (134 ± 5) Ohm/cm3,(100 ± 6) Ohm/cm3 and (118 ± 5) Ohm/cm3,with significant difference between the 3 groups (F =1.04,P ＜ 0.05).Compared with the normoxia group,the TER of the hypoxia group was decreased by 27.7％ (t =7.84,P ＜ 0.05) ; compared with the hypoxia group,the TER of the hypoxia + cyclopamine group were increased by 16.4％,but it was still significantly lower than the normoxia group (t =4.23,P ＜ 0.05).The expressions of ZO-1,Occludin and Claudin-1 were 1.18 ± 0.24,0.80 ±0.13 and 0.90 ±0.09 in the normoxia group,and 0.58 ±0.08,0.32 ±0.05 and 0.50 ±0.09 in the hypoxia group,and 0.92 ± 0.21,0.43 ± 0.10 and 0.82 ± 0.11 in the hypoxia + cyclopamine group,with significant difference between the 3 groups (F =4.95,2.88,10.09,P ＜0.05).The expressions of ZO-1,Occludin and Claudin-1 in hypoxia group were decreased by 48.7％,40.0％ and 55.6％ when compared with the normoxia group (t =12.86,9.35,18.90,P ＜0.05).The expressions of ZO-1,Occludin and Claudin-1 in the hypoxia + cyclopamine group were increased by 59.9％,35.2％ and 65.1％ when compared with the hypoxia group (t =5.63,2.92,6.66,P ＜ 0.05).Conclusion Hedgehog signal pathway could be activated under hypoxia,and then the expressions of tight junction proteins are decreased,which finally induces the injury of intestinal epithelial barrier function.

Gastric bronchogenic cysts （GBCs） is uncommon with atypical clinical features. It is difficult to diagnose by preoperative imaging examinations. Therefore , postoperative histopatho-logical examination is regarded as the golden bacteria in ultimate diagnosis. The treatment of GBCs：ultrasound-guided fine needle aspiration and endoscopic mucosal resection is only used for small GBCs with intra-cavity growth pattern. However , GBCs with extra-cavity growth pattern is featured with deeply anatomical position , large size , and prone on attaching to vital blood vessels and organs , which makes laparoscopic resection is the first choice in treatment. The authors introduce the diagnosis and treatment of a case of GBCs attaching to lesser curvature , in order to provide references for clinical diagnosis of GBCs.

Objective Research the correlation between expression of MMP-2 in colorectal cancer and patho- logical factors,or biological behaviors in colorectal cancer.Methods The expression of MMP-2 in 68 cases with col- orectal cancer were detected by immunohistochemical staining.Results The expression of MMP-2 in colorectal can- cer was not correlated with tumor region and histologic type,but related with depth of tumor invasion and metasta- sis.The frequency of positive cases in patients with colorectal cancer with of lymph,node metastasis was significantly higher than that in patients without lymph node metastasis(P

With the deepening of research in recent years, tumor metabolic reprogramming has gradually become the focus of research, and targeting tumor cell metabolism has also become a new means of tumor therapy. The metabolic process affects almost all the physiological processes of the organism, and lipid metabolism is an important part of the metabolic process. Studies have shown that changes in lipid uptake, storage and fatty acid synthesis and decomposition have occurred in a variety of tumors. Abnormal lipid metabolism will promote the rapid proliferation of tumors. Abnormal expression of a variety of key metabolic enzymes in the process of lipid metabolism is the key to tumor progression. The purpose of this paper is to explain the metabolic regulation of lipid metabolism and related metabolic enzymes in hematological tumors, and to provide ideas for the treatment of hematological tumors.

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 study clinical value of shear wave elastography (SWE) in the evaluation of neck-shoulder myofascial pain syndrome.

METHODSFrom December 2013 to July 2014,30 patients diagnosed as neck-shoulder myofascial pain syndrome were in the treatment group,including 17 males and 13 females, with an average age of (44 ± 3) years old. Thirty healthy people were in the control group, including 22 males and 8 females, with a mean age of (37 ± 5) years old. The patients in the treatment group were treated with manipulation, once every other day, total 7 times. The SWE was used to detect tension part of trapezius muscle of patients in the treatment group before and after treatment, as well as to detect muscle belly at the descending part of trapezius muscle in the control group. The tissue elasticity and Yang's modulus value were recorded and compared.

RESULTSThe tissue elasticity chart of patients in the treatment group before treatment was mainly greenish blue with the score of 3.70 ± 1.53, and the Yang's modulus was (43.4 ± 15.6) kPa. The tissue elasticity figure after treatment was mainly blue with the score of 2.40 ± 0.87, and the Yang's modulus was (29.0 ± 5.9) kPa. Whereas in the control group, the tissue elasticity figure was mainly blue with the score of 1.60 ± 0.72, and the Yang's modulus was (24.0 ± 7.6) kPa. These were statistical differences between the two groups (P = 0.000).

CONCLUSIONSWE can be used as an evaluation method of manipulation treatment for neck-shoulder myofascial pain syndrome, which is an objective and sensitive detection method.
