Objective To explore the surgical safety and clinical efficacy of combined anterograde and retrograde method exposing porta hepatis for the treatment of the intrahepatic cholangiocarcinoma invading porta hepatis.Methods The retrospective descriptive study was conducted.The clinicopathological data of 3 patients with left intrahepatic cholangiocarcinoma invading porta hepatis who were admitted to the Renji Hospital affiliated to Shanghai Jiaotong University School of Medicine from February 2015 to May 2016 was collected.All the 3 patients underwent left hemihepatectomy combined with caudate lobectomy after preoperative lab and imaging examinations and the evaluations of liver function and residual liver volume.The surgical procedures followed as:anterograde dissection of porta hepatis,exposure of hilar plate,left hemihepatectomy combined with caudate lobectomy,right artery resection and reconstruction,hilar cholangioplasty and bilioenteric anastomosis.Observation indicators included:(1) surgical situations:operation time,time of hepatic artery~ anastomosis and volume of intraoperative blood loss;(2) postoperative pathological examinations;(3) postoperative situations:postoperative complications (biliary fistula,hemorrhage,abnormal liver function,gastroplegia) and postoperative chemotherapy;(4) follow-up:postoperative patients' survival and carcinoma occurrence.Follow-up was performed to by outpatient examination up to December 2016.The follow-up included clinical symptoms such as abdominal pain,chills,fever and jaundice,liver function and tumor marker examination,and color ultrasound Doppler or abdominal enhanced computed tomography (CT) was performed to detect carcinoma recurrence.Measurement data was represented as average (range).Results (1) Surgical situations:all the 3 patients underwent successful left hemihepatectomy combined with caudate lobectomy using combined antegrade and retrograde method exposing porta hepatis,including 1 combined with right hepatic artery resection and reconstruction,without perioperative death.The average operation time,average time of hepatic artery anastomosis and average volume of intraoperative blood loss of 3 patients were 493 minutes (range,430-570 minutes),11 minutes and 526 mL (range,450-600 mL),respectively.(2) Postoperative pathological examination showed 3 patients were diagnosed with cholangiocarcinoma,2 with nerve bundles invaded and 2 with No.12 lymph node metastasis,with negative margins of bile duct and hepatic artery.(3) Postoperative situations:3 patients are not complicated with biliary fistula and gastroplegia.One patient with postoperative liver dysfunction after right artery resection and reconstruction underwent anti-infection,hepatoprotection and anti-hepatic encephalopathy therapies,and then was improved and discharged from hospital at 4 weeks postoperatively.The other 2 patients recovered steadily without complications such as hypohepatia,and then respectively discharged from hospital at 17 and 20 days postoperatively.All the 3 patients underwent chemotherapy of gemcitabine combined with S-1 for 8 courses at week 4 or 5 postoperatively.(4) Follow-up:all the 3 patients were followed up for 7-20 months,with good general conditions and normal liver function and without cholangitis symptoms.One patient received right artery reconstruction,and CT reexamination at postoperative month 3 showed fine imaging of right hepatic artery.There was no sign of carcinoma recurrence.Conclusion The combined anterograde and retrograde method exposing porta hepatis for the treatment of the intrahepatic cholangiocarcinoma invading porta hepatis can increase the radical resection rate and surgical safety.

OBJECTIVETo investigate the long-term clinical effects of modified double Endobutton technique for the treatment of acromioclavicular joint dislocations of Tossy type III.

METHODSA retrospective study was done in 42 patients with acromioclavicular joint dislocations of Tossy type III treated with modified double Endobutton technique from December 2008 to December 2010. There were 24 males and 18 females, ranging in age from 21 to 56 years old (averaged, 32.5 years old). All the patients were treated with open reduction, coracoclavicular ligament reconstruction using double Endobutton technique, and repair of acromioclavicular ligament. The Karlsson system was used to evaluate therapeutic effects. The distance from coracoid to clavicle was measured to evaluate reduction loss.

RESULTSAll the patients were followed up, and the duration ranged from 2.0 to 3.2 years (averaged,2.4 years). According to Karlsson system, 32 patients got an A degree and 10 patients got a B degree at three months post-operatively; 26 patients got an A degree and 16 patients got a B degree at the latest follow-up; 6 patients got an A degree at 3 months after operation lowered to B degree at the latest follow-up. The coracoid-clavicle distance increased from (26.91 +/- 0.91) mm at 3 months after operation to (27.41 +/- 1.10) mm at the latest follow-up. Te patients treated with over-reduction during operation or with heavy physical labour work after operation had obvious widened coracoid-clavicle distance. Bone absorption was found around the plate in most cases, mainly in the clavicular side.

CONCLUSIONTreatment for acromioclavicular joint dislocations of Tossy type III with modified double Endobutton technique has satisfactory early clinical results. But with time passing, loss of reduction and bone absorption around the plate could be observed, and clinical outcomes of some cases downgrade during the long-term follow-up.

NSP4, as the diarrhea-related protein of rotavirus, is becoming an attractive candidate for vaccine development. To compare the immunogenicity of NSP4 from different genetic groups, we constructed eukaryotic expression plasmids comprising the NSP4 genes from four different genetic types using the pCI vector. The recombinant vectors were designated as pCI-97B6, pCI-97S36, pCI-97S34 and pCI-97SZ8, respectively. Following the conformation of the transient expression of the constructs in 293 cells, the plasmids were respectively subjected to the 5 round i. m. inoculation of BALB/c mice. The specific antibodies against NSP4 as well as the IgG1/IgG2a subclasses of immunoglobulin in mice sera were examined with indirect ELJSA after each immunization. The results showed that the immunization of plasmids expression NSP4s could elicit not only humoral but also cellular immunity, but the humoral immune response is dominant. There is a difference of immunogenecity among the NSP4 of different genetic type. Further studies were needed to focus on the relationship between the immunogenicity and protection effect.

Objective To determine clinical characteristics and the effects of drug-eluting stents on the occurrence of major adverse cardiac events during percuteneous coronary artery interventional(PCI)and long- term outcomes in patients with chronic renal insufficiency(CRI).Methods Nine hundreds and seventy three patients with angiographically-documented coronary artery disease(lumen inner diameter narrowing＞50%), included 516 patients complicated with experienced renal impairment(CRI group)and 457 with normal renal function(control group).Baseline clinical data and coronary angiographic features were recorded.Results Comparing with control group,patients in CRI group were older with higher incidence of hypertension or diabetes and simultaneously complicated by reduced left ventricular ejection fraction,and more complex coronary lesions(type C).During follow-up(mean 17 months),the mortality was significantly higher in CRI than in control group(6.2% vs 3.3%,P＜0.05),but the former with CRI was significantly lower by using drug-eluting stents in comparing with bare-metal stents(4.1% vs 8.5%,P＜0.05).Conclusion Patients with CRI often complicated with severe coronary artery disease,the mortality after PCI would be significantly reduced by using drug-eluting stents.

Objective To analyse the clinical effect of Quantianma capsules combined with flupentixol and melitracen tablets on chronic migraine. Methods 130 patients with chronic migraine were treated with flupentixol and melitracen tablets, were divided into control group and observation group, 65 patients in each group. The observation group were given to Quantianma capsules. Results The effective rate of observation group with 90.77% was higher than control group with 73.85%(P<0.05). After treatment, the number of migraine attacks, duration time, VAS score, HAMA and HAMD score and mean flow velocity of cerebral artery of two groups were lower than pre-treatment and observation group were lower than that of control group(P<0.05). Adverse reactions were similar in the two groups. Conclusion Quantianma capsules can improve the efficacy of treatment of chronic migraine combined with flupentixol and melitracen tablets and improve condition with few adverse effects.

Objective To learn the control status of iodine deficiency disorders in Baoji City of Shaanxi Province.Methods From 2009 to 2011,according to the National Iodized Salt Monitoring Program,the iodized salt was monitored,and thyroid was examined in 12 counties(areas) of Baoji City.According to rural and urban area stratification,60 children aged 8 to 10 were selected in each county(district),and their urine samples were collected for determination of iodine content.In 2011,per capita daily salt intake was surveyed by the three weighing method at children's home whose urine was collected.Chencang Area,Fufeng County and Taibai County,representatives of Baoji City different geomorphic features were selected for investigation of water iodine,and urinary iodine of pregnant and lactating women,and 15 people were selected in each county (district).Results From 2009-2011,in the 12 counties(areas) in Baoji City,the coverage rate of iodized salt was all 100.00％(3468/3468); the qualified rate of iodized salt and the consumption rate of qualified iodized salt were all ＞ 99.00％.Children's goiter rate was 3.41％(87/2548),3.06％(77/2520) and 3.33％(84/2520),and they were all less than that of the national standard (＜ 5％).Medians of urinary iodine of 8-10 years old children were 368.20,293.80 and 332.50 μg/L,respectively,and the ratios of urine iodine ≥300 μg/L were accounted for 66.42％ (797/1200),48.05％(692/1440) and 56.67％(816/1440),respectively.Median urinary iodine of pregnant women was 301.81 μg/L and lactating women was 329.79 μg/L.A total of 1116 households were investigated,the median of per capita daily salt intake was 8.9 g.Eighteen water samples were collected,range of water iodine value were 0.60-10.25 μg/L.Conclusions Iodine nutrition in general population of Baoji City is exceeded the optimum level,and the current iodized salt concentration has some down space,but fully consideration should be taken on iodine needs in different iodine deficiency areas and among different groups of people.
