AlM: To find out the weaknesses of the cultivation of the Chinese ophthalmology physicians and the gap between Chinese and the international ophthalmology physicians, so that provide the advice on the future cultivation of the Chinese ophthalmology physicians.
METHODS: The passrate of the 2013 lCO examinations taken by worldwide examiners by common statistical methods was analyzed.
RESULTS:The results indicated that the test scores of Chinese candidates' were lower than that of the international average level, there was a obvious gap existed between Chinese and other countries' ophthalmology physicians. lt showed that Chinese candidates were not quite adaptable to this examination, basic science and clinical level needed to be improved.
CONCLUSlON:lt may shows that the effects on the mid-anaphase of our country's ophthalmology residency training are not so good, which area we should pay more attentions.

To investigate the utility of optomap panoramic 200Tx in screening fundus disease among the patients after cataract surgery.
●METHODS: From November 18 th to December 31st , 2013 all 146 post- cataract surgery patients were recruited. All non - mydriatic fundus images were taken with the optomap panoramic 200Tx and were diagnosed by one masked retinal specialist. Non - mydriatic direct ophthalmoscope exam and mydriatic slit-lamp lens exam were also done by other two masked specialists. Comparisons of the three methods were made.
●RESULTS: Among 146 patients ( 161 eyes), 40 eyes (24. 8%) of retinal lesions was detected by non-mydriatic direct ophthalmoscope exam, 59 ( 36. 7%) by non -mydriatic optomap 200Tx exam, and 61 (37. 9%) by slit-lamp lens exam. Nine eyes ( 5. 6%) needed medical intervention immediately. Results of optomap 200Tx exams and slit - lamp lens exams were similar without statistically significant difference ( P > 0. 05), better than direct ophthalmoscope exam ( P < 0. 05) with statistically significant difference.
● CONCLUSlON: Opacification of the refractive medium makes thorough fundus examination impossible. So post-operative fundus examination is highly necessary and should be a routine. Optomap panoramic 200Tx, which shows no statistically difference from mydriatc slit- lamp lens exam, is a convenient and feasible method in discovering fundus pathological changes.

The DNA fragment sized 2 139bp, the same Sequence with AtKup1 gene from Arabidopsis thalianna was used as the templates for DNA family shuffling. The shuffeld AtKup1 gene library was expressed in the mutant of 5. cerevisae in which potassium transporter gene TRK1 and TRK2 were knocked out by homologous recombination. Then the screening was carried out in the low potassium media containing 5. 0 mmol/L KC1 and no histidine in it. it was found that both of diverse and wild AtKup1 gene can rescues the trk1△trk2△yeast mutant strain in low [ K + ] medium. The growth of 2 clones yeast containing diverse AtKup1 were beter than that of AtKup1 wild gene transformant. The sequencig results of the shuffeld AtKup1 showed that there were 2 nucleotide changed, which resulted in 2 amino acid variations in it compared with the original AtKup1. The potassium uptaking capacity of shuffled AtKup1 gene increased significantly when it was transformed into tobacco.

Objective To investigate the clinical characteristics and analyze prognostic risk factors of combined hepatocellular-cholangiocarcinoma. Methods The clinical data of 19 cases of combined hepatocellular-cholangiocarcinoma admitted in our hospital from January 1999 to December 2009 were analyzed retrospectively. The survival function was analyzed by Kaplan-Meier. The possible prognostic risk factors were tested by χ2-test. Results Hepatocellular-cholangiocarcinoma was diagnosed by pathology in the 19 patients, among which hepatic tunic was infiltrated in 13 cases, peritoneum involved in 1 case, intravascular cancer embolus in 1 case. At that time lymphocyte nodes metastasis in 2 cases were found by regional lymphadenectomy in 7cases. The 1-year and 3-year survival rates were 61% and 42%,respectively. Prognosis of patients with tumor size > 5 cm ( χ2 = 4. 392, P = 0. 036 ), history of heavy drinking ( χ2 = 11.010, P = 0.001 ) or intraoperative blood transfusion ( χ2 = 4. 645,P = 0. 031 ) were worse than others. Conclusion It was difficult to get correct preoperative diagnosis of combined hepatocellularcholangiocarcinoma. Tumor size, history of heavy drinking and blood transfusion were all prognostic related risk factors.

OBJECTIVETo evaluate the application of total-cystectomy in the hepatic cystic echinococcosis (HCE).
METHODSAn retrospective analysis was made in 223 cases of HCE. The observation targets included the days post operative, blood loss during operation, complications of residual cavity and local recurrence. The patients were divided into two groups: cyst-resection group and cyst ectomy group. The cyst-resection group was divided into two sub-groups, per cystectomy group and liver resection group.
RESULTSThe incidences of residual cavity and local recurrence in the cyst-resection group were lower than that in the cystectomy group (P < 0.01). The incidences of blood loss and average days in ward in the per cystectomy group were lower than that in partial liver resection group (P < 0.01).
CONCLUSIONSHCE can decrease the complication of liver residual cavity and local recurrence effectively, total cystectomy should be selected as first procedures for treatment of hepatic cystic echinococcosis.

OBJECTIVETo investigate the value of the noninvasive examinations for localization of insulinoma.
METHODSThe clinical materials of 88 cases of insulinoma treated in Peking Union Medical College Hospital between January 2005 and November 2008 were analyzed retrospectively. There were 40 males and 48 females aged from 15 to 74 years old (averaged, 46.5 years old).
RESULTSThe positive rates for localization were 19.3% (17/88), 52.4% (11/21), 95.5% (64/67), 1/6, 30.0% (6/20), 83.9% (26/31), 8/8 and 5/5 respectively in transabdominal ultrasound, enhanced CT, multislice spiral CT pancreatic perfusion, MRI, somatostatin receptor scintigraphy, endoscopic ultrasound, laparoscopic ultrasound and intraoperative ultrasound. Thirty-one multiple tumors in 8 patients were resected. The positive rates of locating the multiple insulinomas of multislice spiral CT pancreatic perfusion and Intraoperative Ultrasound were 48.4% (15/31) and 100% (14/14) respectively.
CONCLUSIONSThe locating diagnosis of insulinoma has came to noninvasive examination era. Multislice spiral CT pancreatic perfusion is the first choice for localization. Intraoperative ultrasound might play an important role in locating tumors for patients with multiple insulinomas.

OBJECTIVETo summarize our experience in the diagnosis and treatment of malignant pancreatic endocrine tumour.
METHODSWe retrospectively reviewed 36 cases of malignant pancreatic endocrine tumours in our hospital from July 1987 to April 2002, and summarized its clinical features.
RESULTSLiver metastasis was the main malignant manifestation of malignant pancreatic endocrine tumours (incidence rate 72.2%). Removals of primary lesion and isolated hepatic metastatic lesion were means of curative therapy. Interventional chemotherapy was an important adjuvant treatment.
CONCLUSIONComprehensive therapy plays an important role in improving the prognosis of malignant pancreatic endocrine tumour.
