Objective To investigate the expression and clinical significance of miR-96-5p in primary hepatocellular carcinoma (HCC) at early recurrence after radical surgery. Methods 61 HCC eryopreservation tissue samples from the liver carcinoma specimens data obtained after radical surgery and banked in our hospital were divided into 2 groups: early recurrence group (33 cases) and non-early recurrence group (28 cases). Aquantitative real-time polymerase chain reaction (qRT-PCR) was performed to detect the expression of miR-96-5p. Results Compared with the non-early recurrence group , the expression of miR-96-5p was observably down-regulated [(0.634 ± 0.783) vs (5.182 ± 11.321), P = 0.043]. The expression of miR-96-5p was correlated to tumor diameter, early recurrence and vascular invasion (P<0.05). Conclusions miR-96-5p are significantly related to early liver cancer recurrence and metastasis. miR-96-5p may be a molecular marker of HCC at early recurrence as well as a target for targeted therapy of liver cancer in future.

Objective To explore the value of contrast-enhanced ultrasonography(CEUS) in brain injuries. Methods ① Models of graded brain trauma were created in brains of 10 healthy mongrel dogs after the animals were anesthetized and the cranium were removed. Conventional ultrasonography(US) and CEUS were performed to observe the characteristics of traumatic region. ② Thirteen patients with traumatic brain injuries were collected to perform intraoperative ultrasonography. The location, depth, size, internal echo and boundary of traumatic brain injuries were clearly displayed. Eight injury sites were chosen to undergo CEUS. Results ① Twelve injury sites in brains of 10 dogs were detected,and CEUS were peformed in 10 lessions, of which 1 was diagnosed with cerebral contusion, 1 with cerebral contusion and cerebral hemorrhage, 7 with intracerebral hematoma, 2 with ventricular hematoma, 1 with blood vessels in intracerebral hematoma. ② Fifteen lesions were detected by preoperative CT scan, but 18 lessions were detected by intraoperative ultrasound. During operation epidural hematomas in 4 cases were detected. After CEUS,the area of lessions was clearly revealed to be extended, the hemorrhage area was exempt from enhancement while peripheral normal cerebral tissue was homogenously enhanced. Conclusions Conventional ultrasonography could display brain injuries. In case of accurate intraoperative encephalocele, intraoperative untrasound conduces to discover delayed intracranial hematoma. Different traumatic brain injuries had their special CEUS findings.

Objective To evaluate the role of endorectal ultrasonography with coupling gel intrarectal filling in preoperative T stage of rectal cancer. Methods One hundred and fifteen patients with rectal cancer underwent endorectal ultrasonography with coupling gel intrarectal filling. The preoperative T stage according to ultrasonic manifestations was compared with histological findings. Results The total diagnostic accordance rate of preoperative T stage by endorectal ultrasonography with coupling gel intrarectal filling was 89.57%. The sensitivity of ultrasonography for T1, T2, T3 and T4 was 93.10%, 61.11%, 96.61%, 88.89%, while the specificity was 97.67%, 96.91%, 89.29%, 99.06%, respectively. The overstaging rate of ultrasonography was 6.96% (8/115), and the understaging rate was 3.48% (4/115). Conclusion Endorectal ultrasonography with coupling gel intrarectal filling is a valuable diagnostic method for T stage of rectal cancer.

Objective To investigate the effects of carboxymethytl pachymaram ( CMP ) on the methylation of SOCS-1 (suppressor of cytokine signaling-1) gene and the in vitro maturation of human mono-cyte-derived dendritic cells (DCs).Methods Human DCs were induced from the peripheral blood mono-cytes in vitro with the treatment of recombined human GM-CSF and interleukin-4 ( IL-4 ) and cultured with different concentrations of CMP (10, 50, and 100 mg/L).The methylation and expression of SOCS-1 gene were analyzed by methylation-specific polymerase chain reaction (MSP) and real-time PCR, respectively. The phenotypic markers of DCs were detected by flow cytometry .Mixed lymphocyte reaction ( MLR) and ELISA were performed to measure the lymphocyte proliferation induced by DCs and IL-12 secretion by DCs . Results CMP promoted the methylation of SOCS-1 gene, but inhibited the expression of SOCS-1 gene in dendritic cells at the concentrations of 50 mg/L and 100 mg/L.The expression of phenotypic markers (CD80, CD83, CD86 and HLA-DR), IL-12 secretion and lymphocyte proliferation induced by DCs were significantly enhanced in a dose dependent manner with the treatment of CMP .Compared with control group , the levels of methylated SOCS-1 gene and IL-12 and the lymphocyte proliferation index were increased upon the stimulation with 50 mg/L and 100 mg/L of CMP (P<0.01), but the expression of SOCS-1 gene was de-creased.The expression of CD80, CD83 and HLA-DR on DCs in the presence of 100 mg/L of CMP were higher than those of control group (P<0.05).Conclusion CMP could induce the methylation of SOCS-1 gene and the maturation of DCs derived from peripheral blood monocytes .

OBJECTIVETo evaluate the safety and effectiveness of transumbilical single port laparoscopic cholecystectomy (TSPLC).
METHODSA retrospective analysis was conducted for the 141 patients, who received TSPLC by DR. Jian in our hospital since April 2011 to October 2012, and the operative and postoperative effects of these patients were evaluated by comparing with that of the conventional laparoscopic cholecystectomy (CLC).
RESULTSIn the total of 141 TSPLC cases that included in the study, 3 cases converted to CLC. 2 cases converted to open cholecystectomy. Additionally, 1 case was diagnosed as an unexplained bowel perforation after operation, fat liquefaction occurred in 2 patients. When comparing with these cases to 306 CLC patients, there was no obvious statistical difference in the terms of patients age, gender, BMI and abdominal surgery history (P>0.05). Meanwhile, There were similar effects of the two groups of patients on the operation time (28.5∓19.3 min vs 33.4∓14.2 min, P=0.001), estimate blood loss (6.4∓18.9 ml vs 9.8∓20.6 ml, P=0.06), the time needed for closing abdomen (5.1∓3.8 min vs 5.8∓4.3 min, P=0.06) and postoperative complications (3/141 vs 5/306, P=1.00). However, the TSPLC group was superior to CLC group in the terms of the conversion rate (2/141 vs 25/306,P=0.001), and postoperative hospitalization (1.2∓1.4 d vs 2.6∓1.7 d,P<0.01), meanwhile, TSPLC was also superior to LC on the satisfactory degree of operative effect through the one week follow-up (8.5∓1.1 vs 7.9∓0.7, P<0.01).
CONCLUSIONSTSPLC is both safer and more effective than that of CLC, and thus it is worth adopting in selected hospitals.

Indocyanine green (ICG) fluorescence imaging technology has been applied in laparoscopic surgery. It is possible to highly visualize the tumor cutting edge and liver segment boundary during laparoscopic hepatectomy. Although the application of this technique in liver tumor surgery has become more and more mature, the factors affecting the quality of fluorescence imaging are still not completely clear. In this paper, we analyzed and summarized the effects of different factors such as ICG administration scheme, imaging acquisition, tumor characteristics of patients and preoperative liver function indexes on the quality of intraoperative ICG imaging, in order to provide new ideas and practical experience for clinical practice and research.

The Laennec capsule of liver was first discovered and reported by French doctor Rene Theophile Hyacinthe Laennec in 1802.However, it has not received enough attention for more than 200 years since then. In recent years, with the rapid development of liver surgery represented by laparoscopic technology, and the deepening of the theory of precise liver surgery, the fine anatomical structure of liver Laennec capsule has returned to the vision of liver surgeons.Recent studies have demonstrated the presence of Laennec capsule in liver histology, covering the whole liver surface, and lining the surface of liver parenchyma around the Glisson pedicle and the main hepatic vein along the inflow and outflow channels of the liver. Based on the Laennec capsule approach, it is expected to unify the current approach of Glisson pedicle and the approach of hepatic vein, and provide a new theoretical basis for the liver surgery, and guide us in the standardization of liver surgeries.
