Objective To study the diagnosis and surgical treatment of Mirizzi syndrome (MS).Method The clinical data of patients with Mirizzi syndrome treated in our center from July 2001 to July 2011 were retrospectively studied and the diagnostic methods,operative strategies and outcomes of surgical treatment were analyzed.Results Mirizzi syndrome (MS) was identified in 56 out of 13800patients who received cholecystectomy (0.4％). MS was diagnosed preoperatively in 30 patients (53.6％).There were 29 patients with Mirizzi syndrome type Ⅰ,17 patients with type Ⅱ,9 patients with type Ⅲ,and 1 patient with type Ⅳ using the Csendes's classification.In two patients (3.6％) coincidental gallbladder carcinoma was detected.An initial laparoscopic approach was attempted in 33patients,and 16 were converted to open surgery.The remaining 23 patients underwent open operation.Surgical procedures included cholecystectomy,choledochotomy and T-tube insertion,simple closure and drainage (via T tube) of the biliary fistula,Roux-en-Y hepaticojejunostomy,radical resection of gallbladder and hepaticojejunostomy.Inadvertent bile duct injury occurred in 2 patients who had an initial laparoscopic approach for a preoperative undiagnosed MS. Postoperative morbidities included biliary leak (n =4) and residual common bile duct stone (n=2).All patients recovered completely and there was no hospital mortality.Conclusions Preoperative diagnosis of Mirizzi syndrome is still challenging despite the availability of multiple imaging modalities.Open surgery remains the standard of care,although laparoscopic treatment may be used in selected patients,especially for type Ⅰ Mirizzi syndrome.Patients with Mirizzi syndrome should be managed differently,basing on intraoperative findings and the type of Mirizzi syndrome.

ObjectiveTo investigate the association of single nucleotide polymorphisms (SNPs)of rs11833579 and rs12425791 on chromosome 12pl3 with cerebral infarction in the Fujian Han population.MethodsA case-control association study containing a total of 216 cases and 279 controls was carried out.The genotypes of two polymorphisms were evaluated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and direct DNA sequencing followed by association analysis.Results The frequency of G ＞ A genotype of rs12425791 in patients with cerebral infarction was lower than that in the controls (34. 3％ vs 43.4％ , x2 = 4. 298 ,P ＜ 0. 05 ) after stratified by causes of cerebral infarction, there was no significant difference in this genotype between large-artery atherosclerosis and controls.Association analysis was performed by logistic regression model after adjusting by sex, age, hypertension, diabetes mellitus, dyslipidemia, smoking and drinking. Rs12425791 G ＞ A genotype was significantly associated with both cerebral infarction ( OR = 0. 627, 95％ CI 0. 417-0. 941, P = 0. 024 ) and large-artery atherosclerosis ( OR =0. 613, 95％ CI 0. 396-0. 949 ,P =0. 028). G ＞ A genotype might be a potential protective factor in male( OR =0. 597, 95％ CI 0. 364-0. 978, P =0. 041 ). rs11833579 G ＞ A genotype frequency was similar between cases and controls.Conclusion rs12425791 G ＞ A on chromosome 12p13 might be a genetic marker for atherothrombotic brain infarction in Han population of Fujian.

Objective To discuss the clinical value of ultrasonic elastography for thyroid nodules,and compared with pathology.Methods 77 patients with 105 thyroid lesions were analyzed.Tissue stiffness on elastography was scored from one(greatest elastics train)to five (no strain).Results On elastography:scores 1 and 2 were found in 75％ benign lesions.Scores 3 to 5 were found in 97.4％ malignant lesions.There were statistically difference in the scores of elastography between the benign and malignant lesions (P ＜0.01).Conclusions The ultrasonic elastography had positive significance in differentiating benign and malignant thyroid nodules.If the score of elastography is more than or equal to 3,the thyroid nodule is highprobablely malignant.

Objective To study the effect of lipoic acid on apoptosis of neurons during experimental neuronal aging. Methods The mouse neuroblastoma cells with serum-free culture were served as experimental neuronal aging models.The cells were randomly divided into control group(serum-free culture)and experimental group(100?mol/L lipoic acid in serum-free culture).After cultivating for 5,10 and 15 d,the cell survival rates were detected by MTT method,and the cell apoptosis rates were quantitatively determined using FACS with Annexin V/PI double staining.Results Compared with those in control group,the cell survival rates in experimental group significantly increased[(212.48?12.26)%vs(100.00?14.80)%,(200.55?28.33)%vs(75.45?10.79)%and(96.81?14.50)%vs(28.54?3.14)%,respectively for 5, 10 and 15 d after cultivation](P

AIM:To evaluate the application and effect of bandage contact lens in pterygium excision combined with conjunctival transplantation (CAT).METHODS:In a prospective, randomized, controlled clinical study, 110 patients (110 eyes) diagnosed with primary pterygium were collected in PLA NO.474 Hospital from January 2015 to January 2016.The 110 patients enrolled in the study in turn, and divided into two groups by the odd and even number.The odd number divided into bandage contact lens group (CAT + bandage contact lens, n=55), while the even number divided into control group (CAT, n=55).Visual analog scale (VAS) and corneal irritation were evaluated on 1, 3 and 7d after operation.Cornea fluorescent staining testing was carried out on 3d after operation.Following-up all the patients with 1a at least observed the recurrence of pterygium.RESULTS:The score of VAS in bandage contact lens group less than that in control group on 1d (4.13±2.06 vs 5.80±1.93, t=4.391, P<0.001) and 3d (2.09±1.36 vs 3.65±1.65, t=5.422, P<0.001) after operation, while there was no significant difference between two groups on 7d (t=1.295, P=0.198) after operation.The corneal irritation in bandage contact lens group less than that in control group on 1d and 3d after operation (P<0.05), while there was no significant difference between two groups on 7d after operation (P=0.052).Cornea fluorescent staining testing area in bandage contact lens group was less than that in control group on 7d after operation (0.33±0.37mm2 vs 2.73±2.21mm2, t=7.921, P<0.01).There was no significant difference in recurrence rate between two groups after 1a operation (P=1.000).CONCLUSION:Bandage contact lens could significantly release pain and corneal irritation, promote the healing of the corneal epitheliums in the defected area, and increase the postoperative comfort level in patients after operation.

Objective To study the effects of a rotating magnetic field(RMF)on Li pilocarpine-in- duced seizure activity and the expression of mGluR1 and mGluR5 in the hippocampus.Methods Thirty rats were divided into 5 groups.Each rat in the model(M),short treatment(ST)and long treatment(LT)groups was treated with intra-peritoneal injections of lithium chloride(60 mg/kg),followed by an intra-peritoneal injec- tion of pilocarpine(35 mg/kg)24 h later.The rats in the ST group were exposed to 20 mT RMF for 20 min ev- ery day for 3 d before seizure induction,while the rats in LT group were exposed to the same RMF for 8 d.The latency,severity and duration of seizure,as well as accompanying symptoms and electroencephalogram data, were recorded,and the expression of mGluR1 and mGluR5 was calculated using an electrophoretic imaging anal- ysis system.Results The duration,times and accompanying symptoms of seizure were significantly decreased in the LT group.The mGluR1 mRNA level and mGluR1/mGluR5 ratio in the M group were markedly increased, but the mGluR5 mRNA level was obviously decreased,while the expression of mGluR1 in the ST and LT groups was decreased,and mGluR5 was increased.Conclusions Seizure activity in rats can be inhibited by 20 mT RMF,and the expression of mGluRl and mGluR5 in the hippocampus of rats suffering seizures can be markedly influenced by longer-term RMF.
