Objective To establish a 3D digitized visual model of the liver to provide anatomical structure for planning hepatic operations and creating accurate computer simulations of the liver.Methods Transverse sections of abdomen were chosen from the Chinese Visible Human dataset. The liver was reconstructed in three dimensions with surface rendering in combination with volume rendering reconstruction. Results Accurately segmented images of the main structures of liver were completed. The reconstructed structures could be displayed singly, in small groups or as a whole and could be continuously rotated in 3D space at different velocities. Conclusion The reconstructed liver is realistic and demonstrates the natural shape and exact position of hepatic structures. It provides an accurate model for the automated segmentation algorithmic study and a digitized anatomical model of the liver.

Objective To study the effects of a cirrhotic environment on the metastasis of liver cancer in mice.Methods Male BALB/c mice were randomly assigned to two groups:cirrhosis group and control group.The cirrhosis group was treated by an injection of carbon tetrachloride intraperitoneally.H22 liver cancer cells were directly implanted under the capsule of each group after cirrhosis was established.The animals were sacrificed at 1,2,and 3 weeks after the operation.The metastatic behavior of the cancer cells was observed by the naked eye and microscopically.Additionally,the adhesion ability of the liver was assessed by measuring the expression of vascular cell adhesion molecule 1 (VCAM-1),E-selectin,and E-cadherin.Results After the operation,the cirrhosis group showed an obvious metastatic tendency in both intrahepatic (14/19) and extrahepatic ways (4/19),compared with the control group's intrahepatic (5/17) and extrahepatic ways (1/17) (P＜0.05).Immunohistochemisty for VCAM-1 and E-selectin showed a significant increase in the cirrhosis (P＜0.05).However,there was no difference observed in the E-cadherin between the cirrhosis and control group.Conclusion A cirrhotic liver environment may promote the metastasis of liver cancer cells by increasing the ability of liver adhesion.

Objective To establish a luciferase labeled McA-RH7777 hepatoma rat model,which could be used for gross observation to further observe the effect of selective ligation of the portal vein and bile duct on tumor growth and metastasis.Methods The luciferase gene was transfected into rat McA-RH7777 hepatoma cells with pCDH-puromycin-CMV as the carrier,which were subcutaneously inoculated into Buffalo rats.Tumor pieces were then heterotransplanted into the left lateral lobe of the allogenic rat liver to observe the tumor growth in vivo.After the successful hepatoma modeling,the rats were randomly divided into three groups,namely the implanted portal vein group with combined portal vein and bile duct ligation,the implanted portal vein group with single portal vein ligation and sham operation group.The rats were executed at the 1 st week and 2nd week after ligation,and the livers were dissected to record the tumor growth and metastasis inside and outside the liver,respectively.Results The tumor formation rates of Buffalo rats after subcutaneous and intrahepatic implantation were both 100％.The fluorescence signal implanted into the liver lobe could be observed in vivo after the intrahepatic implantation of luciferase transfected Luc-McA-RH7777 at 2nd week,the range and intensity of which increased over time.Only local tumor growth could be found at the 4th week,without obvious intrahepatic and lung metastasis.However,both an increased in situ tumor volume and the pulmonary metastasis could be observed in the implanted portal vein group with combined portal vein and bile duct ligation at 2nd week after the ligation.Immunohistochemistry showed AFP positive immunoreactions in the vast majority of intrahepatic tumor cells and Luc positive immunoreactions in part of tumor cells.Conclusion Luc-McA-RH7777 cells could be used to establish the heptoma rat model and the in vivo analysis within the Buffalo rat liver demonstrated that the combined ligation of the portal vein and bile duct can accelerate the development and metastasis of liver cancer.

Objective To build three-dimensional model of the pancreas and peripanercatic organs to provide morphological basis for imaging diagnosis and operation selection of pancreas diseases. Methods Serial cross-sectional images from the first Chinese visible human dataset were reviewed and the structures of pancreas and peripancreatic organs were reconstructed three-dimensionally by using 3D-Doctor software on PC. Results Three-dimensional structures of pancreas and peripancreatic organs were reconstructed successfully. All reconstructed structures could be displayed in multiple methods and color modes. Conclusions The internal and adjacent struc-tures of pancreas can be clearly shown on the reconstructed three-dimensional images. The visible model is a useful reference both for clinical diagnosis and surgical practice.

Objective To develop a hepatic surgical planning software for hepatic operation on deciding the rational operational scheme, simulating procedures before the operation to accomplish the precise operation and decrease the operative risk. Methods The software was used in clinical practice to analyze the surgical anatomy of human liver, calculate the liver volume and vascular territory, disclose the hepatic structures and simulate the operation before operation. Results The surgical planning software is very convenient in analyzing the surgical anatomy of human liver, calculating the liver volume or vascular territory and simulating the operation before operation. Conclusion The developed surgical planning software is very helpful in clearly disclosing hepatic structures, rationally deciding operation scheme and virtually simulating the operation.

Objective To establish the three-dimensional model of pancreas and its surrounding structures.Methods The three-dimensional pancreas model was established and analyzed by using PC computer platform based on the data set from the first Chinese visible human female.Results The three-dimensional pancreas model,established successfully,could be rotated at any angles and could be sectioned at any orientation.The structures of each section could be displayed clearly.Conclusion Sectional anatomy at any orientation of the pancreas and its surrounding structures can be performed on our pancreas model,which has laid the foundation for virtual surgery of the pancreas.

OBJECTIVETo observe the effect of congestion/reperfusion injury (CRI) and ischemia/reperfusion injury (IRI) on remnant liver in rats after hepatectomy.

METHODSMale SD rats were divided into IRI, CRI, and control groups. In the former two groups, the left lateral lobe of the rats were subjected to IRI or CRI for 30 min with the rest lobes (about 70% of the total liver weight) resected; the rats in the control group received hepatectomy preserving only the left lateral lobe. The mortality rate of the rats was recorded, and the surviving rats were sacrificed at 1, 3 and 7 days after operation for analyses of ICG plasma disappearance rate (ICG-PDR), ALT, AST, liver regeneration rate, and Ki-67 labeling index.

RESULTSThe mortality rate was significantly higher in CRI group (34.3%) than in IRI group (8%, P<0.05) and control group (4%, P<0.01). On day 1 following hepatectomy, CRI group showed significantly higher liver enzyme levels and poorer liver functions than the control group (P<0.05) without significant differences from those in IRI group (P<0.05); Ki-67 labeling index in CRI group was significantly lower than that in the control group (P<0.01) and IRI group (P<0.01). Compared with the control group, CRI group showed a significantly lowered maximum Ki-67 labeling index with also a delayed occurrence (P<0.01); CRI resulted in poorer liver regeneration rate on day 3 after hepatectomy compared to the control group (P<0.01) and IRI (P<0.05).

CONCLUSIONCompared with IRI, CRI can result in severer liver damage and lowered liver regenerative capacity in rats early after hepatectomy.

OBJECTIVETo observe the effects differences for polycystic ovary syndrome (PCOS) between periodic therapy of acupuncture and diane-35 and to explore its mechanism.

METHODSSixty patients were randomly assigned into an acupuncture group and a western medication group, 30 cases in each one, 29 patients finally included with one case dropping out respectively. In the acupuncture group, periodic therapy was mainly used at bilateral Sanyinjiao (SP 6), Dahe (KI 12), Guilai (ST 29), Guanyuan (CV 4), Zhongji (CV 3), with different acupoints in the postmenstrual, intermenstrual, premenstrual periods, once every other day, 3 times a week. EA (2 Hz/100 Hz) was used at bilateral Dahe (KI 12) and Guilai (ST 29). If treatment, FSH increased and LH, LH/FSH, T decreased in the two groups (all<0.05), but T level and the different value before and after treatment in the western medication group were better than those in the acupuncture group (both<0.05).

CONCLUSIONSPeriodic therapy of acupuncture is probably one of the effective methods for PCOS, which can improve patients' clinical symptoms, sex hormone level, and menstrual cycle. there was no discomfort during menstrual period, no treatment was given. In the western medication group, diane-35 was prescribed orally for 21 days as a course, with 7 days at interval, one tablet a day. All the treatment was started on the fifth day of the menstrual circle, for continuously 3 months. The indexes were observed before and after treatment, including the menstrual circle, acne score, body mass index (BMI), serum follicle stimulating hormone (FSH), luteinizing hormone (LH), LH/FSH and testosterone (T). The effects of the two groups were compared.

RESULTSThe total effective rate was 75.9% (22/29) in the acupuncture group, which was not significantly different from 79.3% (23/29) in the western medication group (>0.05). The menstrual cycles were shorter after treatment in the two groups (both<0.05), with better effect and different value before and after treatment in the acupuncture group (both<0.05). BMI in the acupuncture group after treatment was lower than that before treatment (<0.05) and that after treatment in the western medicine group (<0.01), with better different value before and after treatment in the acupuncture group (<0.05). The acne scores after treatment decreased in the two groups (both<0.05), without significant difference after treatment between the two groups (>0.05). After treatment,FSH increased and LH,LH/FSH,T decreased in the two groups (all<0.05),but T level and the different value before and after treatment in the western medication group were better than those in the acupuncture group (both<0.05). Conclusion Periodic therapy of acupuncture is probably one of the effective methods for PCOS,which can improve patients' clinical symptoms,sex hormone level,and menstrual cycle.

Objective To evaluate the safety and efficacy of botulinum toxin type A for injection in the treatment of post-stroke upper limb spasticity (dosage was 200 U,or 240 U if combined with thumb spasticity).Methods The study was a multi-center,stratified block randomized,double-blind,placebocontrolled trial.All the qualificd subjects were from 15 clinical centers from September 2014 to February 2016.They were randomized (2∶1) to injections of botulinum toxin type A made in China (200-240 U;n =118) or placebo (n =60) in pivotal phase after informed consent signed.The study was divided into two stages.The pivotal trial phase included a one-week screening,12-week double-blind treatment,followed by an expanded phase which included six-week open-label treatment.The tone of the wrist,finger,thumb flexors was assessed at baseline and at weeks 0,1,4,6,8,12,16 and 18 using Modified Ashworth Scale (MAS),disability in activities of daily living was rated using the Disability Assessment Scale and impaction on pain,muscle tone and deformity was assessed using the Global Assessment Scale.The primary endpoint was the score difference between botulinum toxin type A and placebo groups in the tone of the wrist flexor using MAS at six weeks compared to baseline.Results Muscle tone MAS score in the wrist flexor of botulinum toxin type A and placebo groups at six weeks changed-1.00 (-2.00,-1.00) and 0.00 (-0.50,0.00) respectively from baseline.Botulinum toxin type A was significantly superior to placebo for the primary endpoint (Z =6.618,P ＜ 0.01).The safety measurement showed 10 subjects who received botulinum toxin type A had 13 adverse reactions,with an incidence of 8.47％ (10/118),and three subjects who received placebo had three adverse reactions,with an incidence of 5.00％ (3/60) during the pivotal trial phase.All adverse reactions were mild to moderate,none serious.There was no significant difference in adverse reactions incidence between the botulinum toxin type A and the placebo groups.During the expanded phase three subjects had four adverse reactions and the incidence was 1.95％.All adverse reactions were mild,none serious.Conclusion Botulinum toxin type A was found to be safe and efficacious for the treatment of post-stroke upper limb spasticity.Clinical Trial Registration:China Drug Trials,CTR20131191
