Objective To study the expression of secondary lymphoid-tissue chemokine (SLC)、 CCR7 and its correlation with clinical pathology and lymphangiogenesis in pancreatic adenocarcinoma (PAC). Methods The tissue specimens including PAC, the cancerous peripheral tissues, the normal pancreatic tissues and peripheral lymph nodes were obtained from 30 patients with PAC. The expressions of SLC and CCR7 in these tissues were assayed by immunohistochemical staining and reverse transcription polymerase chain reaction (RT-PCR). MIND marked by VEGFR-3 was detected by morphometric analysis, and the relationship between MLND and clinical pathology of PAC was analyzed. Results In all the specimens, the positive rates of SLC protein in PAC, the cancerous peripheral tissues, the normal pancreatic tissues and peripheral lymph nodes were respectively 16. 7%, 43. 3%, 76. 7% and 46. 6%. The positive rates of CCR7 protein in PAC, the cancerous peripheral tissues, the normal pancreatic tissues and peripheral lymph nodes were respectively 76. 7%, 66. 7%, 30. 0% and 70. 0%. The results of RT-PCR and fluorescence quantitative real-time PCR indicated that the expression levels of CCR7 mRNA in PAC tissues, the cancerous peripheral tissues and peripheral lymph nodes were higher than that in the normal pancreatic tissues ( P <0. 01 ). There was no significant correlation between the expression of SLC protein with MLVD of PAC ( P > 0. 05 ). There was 23 specimens that the CCR7 protein was positive, and among these specimens the MIND was higher than that in negative group of CCR7 protein (P = 0.004). Conclusions The expression of SLC was not related to lymphatic metastasis and TNM stages of PAC. The expression of CCR7 was significantly associated with lymphatic metastasis and TNM stages of PAC, and the high expression of CCR7 in PAC tissues was significantly associated with lymphangiogenesis of PAC.

OBJECTIVETo obtain the data of the genotypes and allele frequencies of 9 short tandem repeat (STR) foci (D18S1364, D12S391, D13S325, D6S1043, D2S1772, D11S2368, D22-GATA198B05, D8S1132, and D7S3048) in Chinese subjects of Li and Han nationalities in Hainan Province.

METHODSA total of 154 randomly selected unrelated subjects of Li nationality and 112 unrelated local Han subjects from Hainan Province, along with 125 Han subjects recent immigrated to Hainan were enrolled in this investigation. Venous blood samples were obtained from the subjects to determine the allele frequencies at the 9 STR loci using multiplex primer extension assay. Statistical analysis was performed to determine the observed heterozygosities (Hobs), polymorphism information content (PIC), individual identification probability (Dp), accumulated power of discrimination, and cumulative rate of exclusion. The genetic polymorphisms of the 9 STR loci was analyzed to acquire the population genetics data.

RESULTSThe genotype and frequency distributions of the 9 STR loci were consistent with Hardy-Weinberg equilibrium. The Hobs, PIC, Dp, cumulative rate of individual identification (CDP), and cumulative chance of exclusion (CCE) showed no significant difference between the 9 foci.

CONCLUSIOND18S1364, D12S391, D13S325, D6S1043, D2S1772, D11S2368, D22-GATA198B05, D8S1132, and D7S3048 STR loci in Chinese Li and Han population in Hainan Province show a high probability of personal identification without obvious difference between the populations, suggesting their value in forensic science and population genetics.

OBJECTIVETo investigate mRNA expression of integrin beta3 in gastric carcinoma, its correlation with microvascular density (MVD), growth-pattern, invasion, metastasis and prognosis.

METHODSIn situ hybridization and immunohistochemistry techniques were used to study the expression of integrin beta3 mRNA and CD34 protein in 105 gastric carcinoma specimens.

RESULTSIn situ hybridization revealed a 30% (6/20) positive rate of integrin beta3 mRNA in non-tumor gastric mucosa, which was significantly lower than that of the gastric cancer group (61.0%, 64/105, chi(2) = 8.85, P = 0.037); In infiltrating type cases (70.2%, 40/57), stage III - IV (72.1%, 44/61), lymphatic metastasis (68.6%, 48/70) and distant metastasis (85.7%, 36/42), the positive expression rates were significantly higher than those of the expanding type (chi(2) = 14.97, P = 0.002), stage I - II (chi(2) = 15.21, P = 0.015), non-lymphatic metastasis (chi(2) = 17.89, P = 0.025) and non-distant metastasis (chi(2) = 20.22, P = 0.005; chi(2) = 21.35, P = 0.035); its mean MVD was also significantly higher than that of the expanding type (t = 10.105, P = 0.001), stage I approximately II (t = 5.961, P = 0.001), non-lymphatic metastasis (t = 3.819, P = 0.01)and non-distant metastasis (t = 10.578, P = 0.001; t = 7.882, P = 0.001), respectively; The mean MVD (41.02 +/- 8.55)/0.72 mm(2) of the integrin beta3 mRNA positive expression group was significantly higher than (25.26 +/- 11.25)/0.72 mm(2) of the negative expression group. There was a positive relation between MVD and integrin beta3 mRNA expression in the tumor (r(s) = 0.316, P = 0.001). The mean survival time in cases with positive integrin beta3 mRNA expression or MVD value >or= 39.5 was significantly shorter than that in cases with negative expression or MVD value < 39.5.

CONCLUSIONSIntegrin beta3 expression correlates with enhanced tumor angiogenesis and may play a role in the invasion and nodal metastasis of gastric carcinoma, therefore it may serve as a prognostic marker of gastric cancer.

OBJECTIVETo investigate the mothod and therapeutic efficacy of total hip anthroplasties (THA) for osteoarthritis secondary to Crowe type IV developmental dysplasia of hip in adults.

METHODSFrom May 2006 to December 2013, THA was performed on 15 adult patients (17 hips) with Growe type IV acetabular dysplasia, including 13 females and 2 males, with a mean age of 30.9 years old (22 to 58 years old) and an average preoperative Harris score of (34.0 ± 6.5) points. Traction of the affected limb was not performed before surgery. After extensive release and lengthening of soft tissues, sub-trochanteric osteotomy of the femur was performed, hip joint center was rebuilt and the abduction function was restored.

RESULTSThe patients were followed up with a mean period of 33 months (ranged from 6 months to 5 years). The postoperative Harris score was 85.0 ± 7.3,higher than the preoperative score. The extended length of limb ranged from 1.6 to 5.4 cm, with a mean of (3.42 ± 0.65) cm. The shortening and malformation of the affected limb were corrected in the most patients,with the difference in length of the two legs less than 1.5 cm. After surgery, 1 patient experienced partial sciatic nerve injury, which was largely recovered after 3 months of conservative treatment. One patient experienced complete sciatic nerve injury, which was partially recovered after 6 months of conservative treatment; a foot-drop varus deformity was formed in the distal end of the affected limb, which was improved after tendon transposition and transplantation. Joint pain was relieved, and the joint function was restored significantly. Over the follow-up period, no severe complications such as dislocation, infection, prosthesis loosening, or subsiding occurred.

CONCLUSIONSatisfactory efficacy can be achieved for adult Growe type IV acetabular dysplasia associated with osteoarthritis by THA, with proper soft tissue release and lengthening, sub-trochanteric osteotomy of femur, joint functional restoration, appropriate choice of prosthesis, and careful protection of nerves and vessels.

OBJECTIVETo investigate the expression of cysteine-rich protein 61 (Cyr61) and NF-kappaB in gastric carcinoma and its correlation with the clinicopathologic features and survival time.

METHODSRT-PCR was used to validate and detect expression of Cyr61 mRNA in 53 gastric carcinoma specimens and 11 non-tumor gastric mucosa samples. Cyr61 and NF-kappaB protein levels expressed were detected using immunohistochemistry in 99 gastric carcinoma specimens and 25 non-tumor gastric mucosa samples.

RESULTSRT-PCR demonstrated that expression of Cyr61 mRNA was higher in the primary carcinoma (84.6%, 22/26) and the metastatic foci (88.9%, 24/27) than in the non-tumor control samples (5/11; P < 0.05, respectively). Cyr61 gene mRNA expression levels were (2.76 +/- 5.50) x 10(-5), (14.61 +/- 20.64) x 10(-5), and (18.46 +/- 26.38) x 10(-5) by 2(-DeltaCt) in the control mucosa samples, primary carcinomas and metastatic tissues respectively. The level was higher in the primary carcinomas and metastatic tissues than that of the non-tumor gastric mucosa (P < 0.05, respectively); however, there was no significant difference between the metastatic tissues and the primary carcinomas (P > 0.05). Immunohistochemistry revealed that of the 99 cases, there was a high expression of Cyr61 and NF-kappaB protein, 56.6% (56/99) and 55.6% (55/99) respectively. There was correlation of Cyr61 and NF-kappaB protein expressions with the depth of tumor and vascular invasion, as well as the development of lymph node metastasis, and TNM staging (P < 0.05, respectively), besides, the expression of NF-kappaB also correlated with the tumor diameter (P < 0.05). Cyr61 expression was positively correlated with NF-kappaB expression in gastric carcinoma (P < 0.05); the mean survival time in cases with a high expression level of Cyr61 and NF-kappaB protein was significantly shorter than those with a low expression level (P < 0.05).

CONCLUSIONSExpression of Cyr61 and NF-kappaB closely correlated with invasion and metastasis of gastric carcinoma. They may be considered as the biologic behavior indicators for gastric carcinoma.
