Intrahepatic cholangiocarcinoma (ICC) is a highly malignant liver tumor with strong invasion and poor prognosis. ICC originates from the bile duct and locates in the liver, so it is classified as either primary liver cancer or cholangiocarcinoma, which the classification is indeterminate and the pathological typing is still debatable. The mechanism of ICC induced by many high-risk factors is still unclear. There are no characteristic manifestations in early symptom and no specific tumor markers, and the diagnosis of ICC mainly depends on imaging examination, which enhanced CT and MRI are the most important evaluation method. TNM staging of ICC is of great significance to guide the treatment, nevertheless, the division of T stage updated by AJCC 8th Edition is still controversial. Radical surgery is the only way to cure ICC currently, but there are still many controversies on definition of R0 resection and the scope of lymph node dissection. The application of local therapy and the rapid development of immunity and targeted therapy bring new hope for the transformation therapy of locally advanced patients, however, the efficacy needs to be verified by multi center large sample clinical studies. To grasp the current focus issues in diagnosis and treatment of ICC timely will be an important direction of basic and clinical research of ICC in the future.

Objective: To explore the effect of bortezomib on migration and invasion of cervical carcinoma HeLa cell and specific molecular mechanism. Methods:The effect of bortezomib on the viability of HeLa cell was measured by MTT assay. The effect of bortezomib on cell migration and invasion was measured by Transwell assay and invasion experiment respectively. The activation of Akt/mTOR signaling pathway and expression level of MMP2, MMP9 were assayed by western blot. Results:MTT assay indicated bortezomib (2.5μM, 5μM, 10μM) could inhibit HeLa cell viability, and the inhibitory rate was highest at 48 h. Transwell assay and invasion experiment results showed that bortezomib inhibited HeLa cell migration and invasion. Western blotting assays presented bortezomib could suppress the phosphorylation of Akt and mTOR, and down-regulate the expression of MMP2 and MMP9. Conclusions:These results suggested bortezomib could inhibit migration and invasion in cervical carcinoma HeLa cell, which might be related to Akt/mTOR signal pathway.

Objective To investigate the clinical value of classic intrafascial supracervical hysterectomy(CISH) by including the clipping of the uterine artery.Methods A total of 60 cases of benign uterine diseases were included in the study.After the uterine artery had been dissected and clipped on both sides under laparoscope,classic intrafascial supracervical hysterectomy was performed.Results All the operations were performed successfully under laparoscope.No conversions to open surgery were needed.Operating complications happened in no case.The operating time was 72~186 min(91.4?26.3 min),the amount of blood loss was 50~150 ml(76.5?20.6 ml),the time to postoperative gastrointestinal function recovery was 18~30 h(22.7?5.8 h),and the volume of pelvic drainage within 24 hours,50~160 ml(80.5?31.8) ml.Postoperative body temperature was elevated to 38.5 ℃ in 2 cases,the postoperative pyrexia rate being 3.3%.The length of postoperative hospital stay was 4~7 d.Follow-up for 6~18 months(10.6?4.2 months) in the 60 cases showed 3 cases of small amount of vaginal bleeding at 1~3 months,which were cured with the use of antibiotics and hemostatics for 5~7 d.Conclusions Classic intrafascial supracervical hysterectomy by including the clipping of the uterine artery is a safe and effective improvement to CISH technique.

Objective To investigate the clinical efficacy of total laparoscopic hysterectomy(TLH) with separating and blocking uterine arteries.Methods From January 2004 to June 2006,68 cases of uterine benign diseases underwent TLH by blocking uterine arteries after separating and clipping uterine arteries with Titanic clip.Results All operations were performed successfully without conversion to open surgery and complications.1 patient,who had twice gastrohysterectomy histories,underwent bipolar coagulating uterine arteries as to the failure of separating bilateral uterine arteries.Pelvic adhesion release was performed in 18 cases,unilateral or bilateral adnexectomy in 14 cases,oophorocystectomy in 8 cases,appendectomy in 1 case,and cholecystectomy in 1 case simultaneously.The operation time was 90-185 min,(112.6?27.5)min.The time of separating uterine artery in one side was 3-15 min,(5.2?3.4)min.The intraoperative blood loss was 50-150 ml,(86.5?39.6)ml.The time to first bowel movement was 18-48 h,(27.3?4.8)h.The rate of postoperative pyrexia was 4.4%(3/68),and the hospital stay was 4-7 d,(5.1?1.8) d.A follow-up period of 2-6 months,(3.5?1.6) months,showed 3 cases of vaginal dropping hemorrhage 1-2 months after operation,which was cured with the use of antibiotics and hemostatics for 5-7 d.Conclusions TLH with separating and blocking uterine arteries is a safe,effective and feasible procedure with less complication,so it is worthy of being recommended.

Objective To study the effect of chronic iodine supplement on thyroid of iodine-deficient rats.Methods Iodine-deficient rat models were made by giving 4- week-old rats iodine-deficient fodder for 3 months.These iodine-deficient rats were then supplemented for 8 months 1-,3- and 6- fold iodine which corresponded to the 3 levels of iodine intake found in our epidemiological study in 3 rural communities.Then changes of thyroid after iodine supplement were observed.Results After supplement of 1-,3- and 6- fold iodine to iodine-deficient rats for 8 months,thyroid relative weight did not recover,and iodine accumulated in thyroid.The ultrastructure injuries of swelling mitochondria and dilating endoplasmic reticulum in epithelial cells of iodine-deficient thyroid did not recover,but became worse with iodine supplement increase.Conclusion Iodine supplement alone can not correct the injuries resulting from iodine deficiency;moreover,a sub-pathological state might occur.

BACKGROUND: Cervical sympathetic ganglia block accelerates the re covery of the homeostasis of organic nervous-endocrine-immune system, butit is still unclear whether it can suppress the imbalance of homeostasis in duced by post-traumatic stress disorder. OBJECTIVE: To observe the effect of cervical sympathetic ganglia blockon the mortality of mice with combined radiation and burn injury, andwhether it can become an easy and effective method to treat secondarydamage after serious trauma. DESIGN: A randomized grouping design, an animal controlled experiment. SETTING: Department of Anesthesiology, Guangzhou General Hospital, Guangzhou Military Area Command of Chinese PLA.MATERIALS: The experiments were carried out in the Institute of Combined Injury, the Third Military Medical University of Chinese PLA between February 2004 and July 2005. Totally 160 Kunming mice were randomly divided into control group (n=50) and cervical sympathetic ganglia block group (n=50). In the control group, the mice were only induced to models of combined radiation and bum injury, and treated with injection of 0.3 mL saline at cervical part. In the cervical sympathetic ganglia block group, the mice were induced to models of combined radiation and burn injury, and then treated with cervical sympathetic ganglia block, once a day for 14 days continuously.METHODS: Methods to induce injury in the animals: ① Radiation injury: The mice were given even radiation of 60Coγ ray (5 Gy) at a distance of 1.5 m to the whole body, the rate of absorptive dosage was (5.17-5.33) mGy/s. ② Burn injury: After the radiation injury, coagulated gasoline was smeared on the back and burnt for 8 s to induce degree Ⅲ burn injury of 15% of the total body surface, which was proved by the pathological section. Methods of cervical sympathetic ganglia block: Cervical sympathetic ganglia block was given bilaterally, and then the mice were injected with 0.2 mL lidocaine (5 g/L), and it was observed whether the symptoms similar to Horner syndrome (hyperemia of conjunctiva, drooping eyelid,blushing, smaller eyeslit) occurred or not at 5 minutes after injection.MAIN OUTCOME MEASURES: The mortality at 2, 5, 7, 10, 20 and30 days after injury and the changes of the numbers of red blood cells,white blood cells and blood platelet in peripheral blood at 7, 14 and 21 days after injury were observed in both groups. The effects of cervical sympathetic ganglia block on the levels of tumor necrosis factor-alpha (TNF-α),interleukin-1β (IL-1β) and interleukin-6 (IL-6) in serum at 3, 6 and 14days after combined radiation and burn injury were also observed.RESULTS: All the 160 mice were involved in the analysis of results without deletion. ① Compared with the control group, the mortalities at 5,7, 10, 15, 20 and 30 days in the cervical sympathetic ganglia block group were significantly decreased [control group: 8%, 22%, 32%, 54%, 74%,82%, 90%; cervical sympathetic ganglia block group: 8%, 14%, 16%, 22%,28%, 34%, 56%]. ② Compared with the control group, the numbers of red blood cells, white blood cells and blood platelets in peripheral blood at 7,14 and 21 days after injury in the cervical sympathetic ganglia block group were significantly increased [at 21 days: red blood cells: 23.21×1012 L-1, 14.58×1012 L-1; blood platelet: 16.87×1011 L-1, 12.57×1011 L-1; white blood cells: 20.65×109 L-1, 14.58×109 L-1]. ③ The levels of TNF-α, IL-1β andIL-6 in serum at 3, 6 and 14 days after injury in the cervical sympathetic ganglia block group were significantly decreased as compared with those in the control group [at 14 days: TNF-α: 189, 365 ng/L; IL-1β: 14, 23 ng/L;IL-6: 70, 132 ng/L].CONCLUSION: Cervical sympathetic ganglia block can significantly decrease the mortality of animals with combined radiation and burn injury,and it is an easy and effective method to treat serious trauma, and the mechanism may be realized through accelerating the recovery of hematopoietic function and suppressing the excessive inflammatory reaction.
