Hepatocellular carcinoma (HCC)is a common malignant tumor in the world,and surgical resection and liver transplantation are two radical treatment modalities,but only 10%-20%of all patients can receive such treatments.In recent years,local therapies including radiofrequency ablation,microwave ablation,cryoablation,and the irreversible electroporation ablation which appeared recently have gradu-ally become the alternative therapies for the patients who are unable to undergo surgery.In addition to local tumor growth control and im-provement in survival outcomes,the ablation technology also helps to downgrade tumor for secondary resection.This article focuses on the re-search progress in radiofrequency ablation alone and in combination with other therapies in the treatment of HCC,compares radiofrequency ablation with other local ablative therapies,and briefly introduces the application of intelligent navigation technology in adjuvant ablation. With the development of medical imaging and progress in related fields,the ablation technology will be widely applied in clinical practice in the future.

Objective: To evaluate the feasibility of autoregressive integrated moving average with explanatory variables ( ARIMAX ) model including meteorological factors on the prediction of influenza-like illness ( ILI ), so as to provide a basis for the monitoring and early warning of influenza. Methods: The ILI data reported by four sentinel hospitals in Yuhang District of Hangzhou from the 1st week of 2014 to the 26th week of 2018 was collected, as well as the meteorological data during the same period. The ARIMAX model was established using the percentage of ILI cases in total outpatients ( ILI% ) data from the 1st week of 2014 to the 52nd week of 2017 and the meteorological factors selected by Lasso regression model. The ILI% from the 1st to 26th week of 2018 was predicted and compared with the actual values to verify the ARIMAX model. Results: From the 1st week of 2014 to the 26th week of 2018, a total of 60 419 cases of ILI were reported by the four sentinel hospitals of Yuhang District, with ILI% of 1.29%. Lasso regression analysis showed that there was a positive correlation between weekly average absolute humidity and ILI% ( r=27.769 ), and a negative correlation between weekly average temperature and ILI% ( r=-0.117 ). The ARIMAX (1, 0, 0) ( 1, 0, 0 )12 with weekly average temperature and absolute humidity was selected as the optimal model, with the Bayesian information criterion (BIC) value of 81.30 and the mean absolute percentage error (MAPE) value of 15.77%. The MAPE value of the ARIMAX model predicting the ILI% from 1st to 26th week of 2018 were 43.75%. Conclusion The ARIMAX model including meteorological factors can be used to predict the prevalence of ILI, but the accuracy needs to be promoted.

The length and diameter of trachea,bronchus and segmental bronchi were mea-sured from 70 cases (50 adults and 20 children).The length of the segmental bronchi of left lower lobe is always longer thanthat of left upper lobe.The length of the segmental bronchi of right lung showed a regular decreasefrom lower lobe to upper lobe.Using the multivariate statistical analysis the correlations between internalindices such as the length,diameter etc and external indices such as the height dia-meter of chest etc were also studied.

Objective To analyze the congenital anomalies of inferior vena cava (IVC) with their color Doppler and clinical features, and to evaluate the value of color Doppler ultrasound in the diagnosis of congenital anomalies of the IVC. Methods Between July 2009 and March 2012, 22 patients who were diagnosed as IVC anomalies by color and spectral Doppler ultrasound were retrospectively analyzed. After careful and comprehensive scanning on multiple planes, the final diagnosis was made based on the findings obtained on B-mode, color Doppler and spectral Doppler ultrasound. All the results obtained by sonography were compared with computerized tomography angiography, digital subtraction angiography, and other clinical examinations. Results There were 22 cases diagnosed as congenital anomalies of IVC, including 5 cases of the left IVC, 3 cases of the double IVC, 3 cases of membranous obstruction of the IVC (MOVC) and 11 cases of the anomalies of the left renal vein. In left IVC, the infrarenal left-sided IVC entered into the left renal vein, then crossed anterior to the aorta to join the right-sided suprarenal IVC. In double IVC, bilateral IVCs could be seen on both sides of the abdominal aorta, and the left IVC joined the right IVC over aorta then entered into the right atrium. Some patients of the left IVC and double IVC had left renal vein hypertension. All the cases of MOVC in our study presented as Budd-Chiari syndrome, in which B-mode ultrasonography showed the existence of the membranous obstruction in inferior vena cava at the level of entrance to the right atrium. On color Doppler lfow image (CDFI), reverse blood lfow into lumbar and ascending lumbar vein was found. Eleven cases of left renal vein malformations were also seen in present study, including 9 cases of retroaortic
left renal vein, 1 case of circumaortic left renal vein and 1 case of the left renal vein into the left common iliac vein. Among them, 9 cases were associated with left renal vein hypertension. Conclusion Color and spectral Doppler ultrasound can clearly identify the congenital anomalies of IVC with the evaluation of their hemodynamic modiifcation, and can be used as an important approach in the diagnosis of the anomalies of the IVC.

RESULTS:By strengthening training,improving ward baseline insulin management register system,adjusting the specification of insulin in information system, etc.,the application and storage of insulin became more standard;no expired drugs occurred;the rate of waste drug decreased from 95.06% before management to 22.00% after management,decreasing by 73.06%. CONCLUSIONS:PDCA cycle can im-prove the safety management of Insulin injection in wards effectively.

Objective To study the clinical appilication of detachable balloon embolization techenique in carotid cavernous fistula. Methods 27 cases consisted of 26 cases of typical TCCF and 1 case of CCF caused by left anterio cerebral artery(A1) aneurysm ruptured . 27 cases were treated by endovascular embolization with detachable balloon. Transcranial Doppler ultrasound(TCD) was used before and after embolization.All the patients were followed-up for more than 6 months. Results 22 cases of TCCF were cured by detachable embolization and their internal carotid artery(ICA) remained patent. The first segement of left anteriol cerebral artery was embolized by two detachable balloons in the patient with CCF caused by ruptured aneurysm. Internal carotid artery was embolized by two balloons in 4 cases. There was no severe complication in this group. Conclusions Detachable balloon embolization is a safe and effective method for internal carotid cavernous fistula.

Objective To discuss the clinical application of lapraroscopic subtotal cholecystectomy in the acute cholecystitis with severe inflammatory and fibrous adhesions at calot triangle.Methods Retrospective analysis of the clinical data,surgical approaches,and short term and long term complications of 74 cases of acute cholecystitis in the period from January 2002 to September2005 in our hospital.Results In the 74 cases operated by subtotal cholecystectomy using laparoscopy,during laparoscopic procedure,71(95.9%) operations were successful;a case of Mirizzi syndrome could not be confirmed to have the residual stones in cystic duct and another case of the same syndrome was not confirmed to have the duodenum fistula.These two cases were then dealt with by conventional surgery and constituted 2.7% of the total cases.One case was dealtd with by second surgery because of the residual stones of cystic duct after lapraroscopic subtotal cholecystectomy and constituted 1.3% of the total cases.One case was found with minor bile leakage and constituted 1.3% of the total cases.Cholangiography was conducted 41 cases during operation,of whom,39 cases were normal and 2 cases failed.No death occurred with the operation of the lapraroscopic subtotal cholecystectomy.Conclusion It is safe and effective to apply laparoscopic subtotal cholecystectomy to treat acute cholecystitis with severe inflammatory and fibrous adhesions at calot triangle.

Objective To investigate the effect of nifedipine on brain edema and neurological function in patients with cerebral hemorrhage . Methods 72 patients with ICH from October 2013 to October 2015 in our hospital were selected, and randomly divided into experimental group and control group, 36 cases in each group.The control group used dehydration to reduce intracranial hypertension, improve cerebral circulation, promote nutritional metabolism and anti infection and other conventional treatment,and the experimental group daily intravenous infusion of 1.0 mg of nifedipine on the basis of control group, a course of ten days.The activity dependence, clinical efficacy, MESS score, ICH score, BI score, brain hematoma and brain edema volume were observed and compared between the two groups before and after treatment.Results After treatment, the activity dependence of the experimental group was significantly better than that of the control group ( P <0.05 );the clinical effective rate of the experimental group was significantly higher than that of the control group (P<0.05).BI scores of both groups were increased after treatment, MESS scores were reduced(P<0.05);The BI score of the experimental group was significantly higher than that of the control group (P<0.05),and the MESS score was significantly lower than that of the control group (P <0.05).The volume of cerebral hematoma and the volume of cerebral edema were significantly reduced after treatment in both groups (P<0.05),there was no significant difference in the volume of cerebral hematoma between two groups,there was significant difference in the volume of cerebral edema between two groups (P <0.05).Conclusion Nifedipine can effectively reduce cerebral edema in patients with cerebral hemorrhage, reduce the degree of neurological deficit, improve clinical efficacy.
