Hepatocellular carcinoma (HCC) is the most common malignant cancer in China. The size of HCC can be categorized into 4 grades: (1) micro-HCC, the diameter of the HCC is ≤2 cm; (2) small HCC, the diameter of the HCC is between 2 and 5 cm; (3) large HCC, the diameter of the HCC is between 5 and 10 cm; (4) giant HCC, the diameter of the HCC is > 10 era. The new classification helps to choose the appropriate methods and to analyze the curative effect for various kinds of HCC respectively. The resection of large and giant HCC is safe and feasible. During the past 20 years, we have modified and innovated some techniques of HCC surgery, including hepatectomy without dissecting the hepatic hilus, increasing the safety time limit of portal pedicle occlusion from 15-20 minutes to 20-60 minutes, in situ bepatectomy with occlusion of hepatoduodenal ligament and infrahepatic vena cava, and double hanging maneuver techniques. The techniques mentioned above improved the bleeding control of hepatectomy, and enhanced the long-term survival rate of HCC patients.

ObjectiveTo explore the influence of different hemostatic measures of laparoscopic ovarian cyst removed on ovarian function.MethodsSeventy patients with ovarian cyst who performed laparoscopic ovarian cysts removed between January 2009 and December 2010 were randomly divided into group Ⅰ (23 cases) and group Ⅱ (47 cases) by mechanical sampling.Group Ⅰ with bleeding electrocautery,group Ⅱ with suture.Estradiol,follicle puncture hormone (FSH),luteinizing hormone (LH),number of sinusoidal follicles,normal ovarian function and the number of declining ovarian reserve were compared in two groups before operation and after 6 months operation.ResultsAfter operation,the proportion of group Ⅱ with normal ovarian function was significantly higher than that of group Ⅰ[80.9％(38/47) vs.39.1％(9/23),P ＜ 0.05 ],estradiol and number of sinusoidal follicles were significantly higher than those of group Ⅰ [( 198.4 ± 24.4) pmol/L vs.( 153.4 ± 16.8) pmol/L,7.1 ± 2.4 vs.5.8 ± 0.9](P＜ 0.05),FSH and FSH/LH were significantly lower than those of group Ⅰ[ ( 10.58 ± 4.57) U/L vs. ( 13.72 ± 2.58) U/L,2.34 ± 1.32 vs.2.82 ± 0.88 ] (P ＜ 0.05).ConclusionDuring laparoscopic ovarian cyst removed,using electrocautery can significantly reduce residual ovarian function,but using suture hemostasis can effectively protect residualovarian function.

Medical English is a kind of professional English. Its technical terms are always too long to remember easily. For those who are aiming at mastering such professional English, memorizing words efficiently and scientifically is especially important. While medical terms are closely connected with common English words, they have some of their own forming characters. If these specialities are understood and used properly, the remembering work will become easier, firmer and more accurate.

To perfect the medical ethics archives,we should stress the filling system of medical ethics evaluation,the detailed check and registration of medical staff's medical ethics condition.It could form the right think leading and normative professional criterion of medical staff,developing their work potential and decrease the conflict between doctors and patients.The main purpose and significance to establish and perfect the medical ethics archives is that it could bring the guidance,self-discipline,awards and punishments and regulation role in the medical ethics construction.

36 children of exotropic amblyopia, 20 of constant exotropia and 16 of intermittent exotropia, were performed multi-channel VEP examinations to find that all amplyopic eyes manifested VEPs of lower amplitude and longer latency. With full-field stimulation to both eyes, summation of VEP was absent in the group of constant exotropia while it was weakly present in the group of intermittent exotropia. With half-field stimulation, temporal retinal suppression was noted in all healthy eyes and some of the amblyopic eyes of the intermittent exotropia group while it was absent in the amblyopic eyes of the constant exotropia group.

Caudate lobectomy is still a great challenge for surgeons due to unique anatomy of caudate lobe.A 38-year-old male patient with a huge recurrent hepatic cancer (diameter =16 cm) in caudate lobe received caudate lobectomy with portal triad and inferior vena cava clamping.The operation was paused due to hemorrhage (volume of blood loss =1000 ml).After heat preservation and blood transfusion,the caudate lobectomy was completely removed with inferior vena cava clamping.The patient gradually recovered,and no tumor recurrence was detected during the follow up (14 months).Caudate lobectomy could be safely carried out under the condition of accurate preoperational estimation,clear indication for surgery and precise hepatectomy.

Objective To understand the distribution characteristics of HIV infection status among the outpatients in this hospi-tal to provide the beneficial supplement for local large-scale survey and the basis especially for the hospital infection control.Meth-ods The HIV screening situation on the outpatients of our hospital from 2007 to 2012 was retrospectively analyzed.Results Dur-ing these 6 years,108 999 specimens were detected,88 cases were positive in the preliminary screening and 81 cases were confirmed positive.The positive rate of anti-HIV antibody was 0.074%.In addition to voluntary counseling and testing,the specimens submit-ted by the outpatient anorectal department and the inpatient hematology department had the higher positive detection rate,which was 1.16% and 0.84% respectively.Conclusion The HIV infection rate in non-infectious disease specialized hospitals shows the increasing trend.The key departments must increase the intensity of the medical staff training,pay attention to early diagnosis of HIV/AIDS,prevent the hospital infection and reduce the risk occurred after the occupation exposure.

With the era of precision hepatic surgery coming,the hepatic surgery has been promoted to brand-new level,which would be more accurate and meticulous.However,all those advances,such as super-thin computed tomography scan,three-dimensional imaging and the technology of threedimensional printing,have not promoted the clinic results for patients overtly.The optimal curative effect could be attained,if there is a perfect combination of operators' experience and those advanced imaging.For two issues,the time of vascular inflow occlusion and residual hepatic volume,operators could flexiblely use of clinic existing researches with surgical team and instruments according to the medical condition of patients.Precision hepatic surgery could be promoted to a higher level through constantly clinical research and innovations.

Chemoprevention of cancers is still very important since we have not got effective treatments for them.Many natural products(e.g.extracts from plants) or chemical synthetic substances(e.g.additives in foods) were used as chemoprevention regents.Some of them fight the carcinogens or other toxins through induction of the phase 2 antioxidant enzymes.Recently,it is wildly believed that the mechanism of this induction is the activation of Keap1-Nrf2-ARE signaling pathway.Thus understanding of this signaling pathway will widen the field of the cancer research and chemoprevention.
