I uptake of thyroid and color Doppler flow imaging (CDFI) of superior thyroid artery (STA) were performed in 20 patients with Graves′ disease (GD) and 19 patients with other causes of hyperthyroidism. Maximum velocity and diameter of STA in patients with GD were much higher than those in non-GD group. CDFI of STA seems to be a useful tool in differential diagnosis of hyperthyoidism.

Objective To investigate the relationship between truncating mutations of APC gene and sporadic colorectal cancer,and analyze the feasibility of non-radioactive protein truncation test (PTT) in the detection of mutations of APC gene.Methods Ninety-six samples of sporadic colorectal cancer tissues ( including 44 patients with colonic cancer and 52 patients with rectal cancer) were obtained from the General Hospital of Ningxia Medical University from September 2008 to September 2010.The mutation cluster region of the APC gene was screened using digital PTT labeled with fluorescent Lys-t-RNA,with a polymerase chain reaction fragment amplified from genomic DNA serving as a tenplate for in vitro translation.The occurrence of gene mutation was determined according to the emergence of truncated peptides.The mutation cluster region of the APC gene in 46 samples of colorectal cancer tissues was analyzed by direct sequencing.The detection rates of the 2 methods were compared by chi-square test.Results Thirteen (26%) truncated peptides were detected in the 50 samples of colorectal cancer tissues.The mutation type of 4 samples is nonsense mutation,which resulted in emergence of truncated gene products.Eleven (24%) truncated peptides were detected in the 46 samples of colorectal cancer tissues.There was no significant difference in the detection rates between PTT and direct sequencing ( x2 =0.033,P > 0.05 ).Conclusions Truncating mutations of APC gene are common alterations in sporadic colorectal cancer in the Chinese.Digital PTT labeled with fluorescent Lys-t-RNA is rapid and high-sensitive in screening gene mutations.

Objective To improve the knowledge,diagnostic level on concealed penis in children,and explore the operative treatment methods of concealed penis.Methods Ten children with concealed penis were reviewed retrospectively in the First Hospital of Jilin University from Jun.2005 to Jul.2007.Patients were 6-12 years old.Penis length was 1.2-2.6 cm.Patients growthing and micturition were normal,the results of androgne and estrogen examination were normal.The etiology was simple obesity in one case,fiber streak of penis sarcolemma in 9 cases.The clinical symptoms and signs,diagnosis and operative method were analyzed.Results The diagnosis of 10 children were correct,and all patients were treated by Devine's operation and 10 cases patients had healed in one stage.There was no vessel,nerve and urethra injury during the operation.The length of penis was 3.0-5.5 cm,average in 3.6 cm after operation.Followed up 3 months to 2 years,10 children's phimosis were removed,the micturition were normal;the appearance of penis was also satisfactory after operation.One patient with under-developed penis had a amelioration after treatment with HCG postoperatively.The penis contour was dissatisfactory in 1 obesity patient,but it was ameliorated gradually while growing up.Conclusions The correct diagnosis and differential diagnosis are very important for operative treatment depend on the different etiology and pathologic changes of concealed penis.Suitable operation can extend the length;moreover,ameliorate the symptom of micturition and the appearance of the penis.

Objective To study the method and therapeutic results of intra-arterial interventional treatment (selective intra-arterial fibrinolysis) in acute cerebral infarction(ACl).Methods A total of 106 patients with ACI are divided into two groups:selective intra-arterial fibrinolytic therapy group(SIAF),intra-venously thrombolysis group(IVF);SIAF is selective entered into the obliterative artery with improved Seldinger's technich,pumped urokinase(UK) in a dose of 500 000 i.u.in NS.60ml within 40 minutes;arteriography is done all the time to know if the obliterative artery is unobstruct- ed,if it remains obstructe,then pumps 300 000 i.u.of UK,as long as it unobstructed,the treatment is finished at once; IVF is injected 1000 000 i.u.of UK in NS.150 mL by intravenous drip within 40 minutes,others like SIAF.Results The artery is disobliteration after thrombolysis,48 patients in SIAF,30 patients in IVF,P

AIM: To explore the effects of processing on components group of Semen Raphani. METHODS: By comparing HPLC maps of Semen Raphani samples prepared with different methods and computing similarity,(analysis) the change law of the components group. RESULTS: The mechanism of inhibiting the enzyme by processing Semen Raphani was found and C3 was able to produce new compounds A209,B221. CONCLUSION: Processing Semen Raphani can change the components group through influencing the decoction process,eventually produce different clinical effects.

ObjectiveTo investigate the mental health of freshmen of university.MethodsSymptom Checklist 90 (SCL-90) was used to self evaluate 7763 freshmen of university in Ningbo.Results and ConclusionThe overall level of the mental health of this group was higher than that of the Chinese module, and the prevalence of psychological symptoms was 13.2%. The average level of mental health of female were inferior to male. The difference between the students from cities or towns and from the countryside were distinct. Students who were satisfied with their majority get noticeably higher average score than the ones who were not satisfied.

Background Excimer laser corneal refractive surgery is widely used because it reduces the dependency of refractive error eye to glasses.However,the adverse effects of anti-inflammatory drugs is a problem after operation.Lotemax eyedrops is a kind of steroidal anti-inflammatory drug,with a good effect on the operative eye.But its influence on intraocular pressure(IOP) after long-term topical administration is less studied.Objective This study was to investigate the influence of lotemax eyedrops on IOP after long-term topical administration in myopic eyes received excimer laser corneal refractive surgery.Methods An one-month retrospective case serial study was adopted.The case history data of 1552 eyes from 1552 Patients who received excimer laser corneal refractive surgery were collected in Tangshan Eye Hospital from 2011 January to 2012 January,including 321 eyes with laser in situ keratomileusis(LASIK),608 eyes with sub-Bowman keratomileusis (SBK) and 623 eyes with femtosecond laser for flap excimer laser in situ keratomileusis(FS-LASIK).Lotemax eyedrops was topically administered after operation 4 times per day initial and then decreased 1 time weekly for 1 month.IOP was measured in before,1 week,2 weeks,3 weeks,4 weeks after operation with non-contact tonometer.The increasing range of IOP was divided into <5 mmHg,5-15 mmHg and > 15 mmHg after operation.Optical head parameters were measured by Heidelberg retina tomography when IOP increasing after operation.Results Within 1 month,elevated IOP was found in 47 of 1552 eyes after administration of lotemax eyedrops,including 3.12% (10/321) in the LASIK group,3.29% (20/608) in the SBK group and 2.73% (17/623) in the FS-LASIK group,without significant difference among them(x2 =1.95,P>0.05).The IOP elevated 1 week after operation and remained normal after that till drug withdrawal in all eyes.There were no significant differences in the disk area (1.65 ±0.44) mm2 vs.(1.66 ±0.44) mm2,disk volume (0.40 ±0.09)mm3 vs.(0.39±0.08) mm3 and mean nerve fiber layer thickness (0.28 ± 0.08) mm vs.(0.29 ± 0.07) mm in IOP elevation duration compared with 1 month after IOP recovery(t =0.34,0.81,0.48,P>0.05).Conclusions Topical administration of 0.5% lotemax eyedrops after excimer laser corneal refractive surgery leads to reversible high IOP.It is very important to monitor the IOP during use of the drug.
