Hepatocellular carcinoma (HCC) is one of the most lethal human cancers in China. The specific molecular mechanism of its occurrence and development is unclear. Krüppel-like factor family (KLF), which includes 17 members, is a highly conserved transcrip-tion factor family with zinc finger structure. The mechanism of KLFs and the pathogenesis of HCC have been studied in recent years. Re-search revealed that KLF2, KLF4, KLF5, and other KLF family members could be involved in the progression of proliferation, differentia-tion, invasion, and metastasis of HCC. This review summarizes the function and the mechanism of transcription factors KLF in the oc-currence and development of HCC.

OBJECTIVETo study the ischemic times of the main artery injury in the limbs and the influence on the limbs survival rate, and to analyze the reasons for the formation of the ischemia time.

METHODSFrom June 1996 to November 2012, 83 patients with completely severed limb main artery treated in our hospital were retrospectively studied. There were 77 males and 6 females, including 81 adults (ranging in age from 16 to 52 years old, with a median age of 35 years old) and 2 children (4 and 5 years old respectively). Seventy-five patients were treated with end to end anastomosis, 7 patients were treated with great saphenous vein transplantation, and 1 patient was treated with artificial blood vessel transplantation. The prior to admission ischemia time, after admission ischemia time and total ischemia time for successful and unsuccessful patients, as well as the causes of the formation of the ischemia time were studied. Limb survival rate of different ischemic time was counted. Sharpness injury or blunt injury ischemia time and amputation rate were researched statistically. All data were analyzed using SPSS statistical software.

RESULTSThere were 72 limbs survived, 11 amputated. The average ischemia time was (7.45±5.94) h for limb-salvage group and (13.73±14.00) h for amputation group. Prior to admission ischemia time between amputation and limb-salvage group had no significant difference. After admission the ischemia time in amputation group was longer than limb-salvage group. The amputation rate for ischemia time 21 to 44 h group was higher than other three groups (≤ 5 h, 6 to 10 h, 11 to 20 h) (P=0.023, 0.038, 0.044). Amputation reasons can be divided into anastomosis failure in the operation, vascular thrombosis 2 to 4 days after operation and late infection.

CONCLUSIONVascular injury limbs can tolerate longer ischemia time and the limb salvage succeed. Only too long ischemia time (> 20 h), limb amputation rate increases significantly. The main cause of long time ischemia is delayed diagnosis in the hospital. Whether limb-salvage success mainly depends on the degree of trauma and the quality of the anastomosis than ischemia time.

OBJECTIVETo study the influence of actual defect length and gap width of the limbs main artery on the method selection of repairing and reconstruction.

METHODSRetrospective study was carried out for 32 patients with extremity main artery injury from 1996 to 2009, including 30 males and 2 females; 30 adults with an average age of 36 years old ranging from 18 to 51 years, 2 children of 4 and 5 years old respectively. Injured body parts involved axillary artery in 4 cases,brachial artery in 7 cases,radial artery in 2 cases, femoral artery in 4 cases, popliteal artery in 13 cases, posterior tibial artery in 2 cases. Main arterial injury defect gap width of all cases were observed and the reasons were analyzed. All cases were repaired by the method of end to end anastomosis after vessels stretch.

RESULTSThe artery defect width was 3 cm to 7 cm with an average of (4.375 +/- 1.200) cm. Defect width of the upper extremity brachial artery and axillary artery group was (5.73 +/- 0.63) cm,the lower extremity femoral and popliteal artery group (3.80 +/- 0.73) cm, the posterior tibial artery group (3.25 +/- 0.35) cm, the radial artery group (3.00 +/- 0.00) cm. Defect width of upper extremity brachial artery and axillary artery group was larger than that of the other three groups (P < 0.01). End to end anastomosis was performed successfully in all cases. Blood supply recovered well. Because of the severe limb infection 2 patients had amputation in the late. All patients received follow-up. The patients without fracture were followed up to 2 weeks postoperatively, all patients with fractures were followed up to 1 year at least. Limb blood supply was good in all patients during the follow-up.

CONCLUSIONBlood vessel defect gap width is different from the actual vessel defect, but is larger than the actual vessel defect. Misjudgment of the vascular defect length will lead to more vascular transplantation. The vast majority of vascular defect can be directly repaired by the method of end to end anastomosis after the vessel free and stretch.

Objective To investigate the changes of umbilical adiponectin(APN) levels in newborn whose mothers with gestational impaired glucose tolerance (GIGT).Methods Eighteen neonates of GIGT pregnancies and 50 controls of normal glucose tolerance (NGT) pregnancies were studied.APN concentration was qualified in the umbilical vein serum with radioimmunoassay methods.Capillary blood glucose was measured at the first hour after delivery.Results Umbilical APN level in the GIGT group was significantly higher than that in NGT group [(61.06?16.85)mg/L vs(48.04?15.47)mg/L,t=2.38 P0.05).Conclusions Umbilical serum APN levels are elevated in newborns of GIGT mo-thers.This may be due to the dysregulation of serum APN levels associate with GIGT pregnancy.More attention shall be paid to the metabolic changes of GIGT mothers and their offspring.

Objective To compare the therapeutic effects of recurrent pterygium treated by microsur- gical management.Methods Sixty-two cases(67 eyes)with recurrent pterygiumwere randomly divided into limbal stem cell autograft transplantation comblined with mitomycin C(34 cases38 eyesand limbal stem cell autograft transplantation(28 cases29 eyes)The post operative follow-up period was 6 to 30 months.Re- suits One eye recurrence was noted in the trial groupthe recurrent rate was 2.63%Three eyes recurrence was noted in the control groupthe recurrent rate was 10.34%There was statistical significant difference be- tween two groups(P0.05).Conclusion Limbal stem cells autograft transplantation combined with mitomycin C can decrease the recurrent rate.It is an ideal methods of recurrent pterygium surgical procedureis worth spreading.

By collecting and studying Practical Acupuncture written by XU Yi-nian, Guangdong acupuncture master in the Republic of China, and using literature methodology, the life story of XU Yi-nian is textually researched and his acupuncture characteristics is analyzed. The results indicate that XU Yi-nian emphasizes on the utility of acupuncture manipulations and acupoint selection, the application of folk experiences in moxibustion and Sha disorders. He pays attention to the co-work of acupuncture and medicine and his work collects the therapeutic experiences of different schools and deserves to be further explored and validated.
