Objective To investigate the effect of tripterysium glycosides combined with isotretinoin in cysticacne and its effect on serum inflammatory factors, insulin like growth factor 1 (IGF-1) and dehydroepiandrosterone (DHEA).Methods 118 cases of cysticacne patients were divided into observation group (n=59) and control group (n=59) according to the random number table method.Patients in the control group were treated with isotretinoin capsule, while the observation group were treated with tripterysium glycosides tablets on the basis of the control group.The course of treatment was 8 weeks in two groups.Results The total efficiency of the observation group (89.83%) was higher than the control group (71.19%) (P<0.05); the number of cyst after treatment in the observation group were less than the control group (P<0.05);the serum IL-2 and IL-4 levels in the observation group after treatment reduced, and lower than the control group (P<0.05);the serum IGF-1 and DHEA levels in the observation group after treatment reduced, and lower than the control group (P <0.05); the recurrence rate of the observation group (11.86%) was lower than the control group (30.51%) (P<0.05);the adverse reactions in two groups had no statistically significant.Conclusion Tripterysium glycosides combined with isotretinoin capsule has obvious curative effect in the treatment of cysticacne patients, and can reduce the serum IL-2, IL-4 levels and IGF-1 and DHEA levels, with lower recurrence rate, fewer adverse reactions.

Coats disease is a relatively rare and idiopathic disorder characterized by retinal telangiectasia and massive intra-retinal and (or) sub-retinal lipid accumulation, resulting in complications including retinal detachment and neovascular glaucoma. Previous reports have revealed that Coats disease can be associated with other disorders, especially some inherited diseases, such as retinitis pigmentosa (RP) and facioscapulohumeral muscular dystrophy (FSHD). Coats disease associated with other inherited disorders is generally called Coats-like retinopathy, which has some unique features that differs from the classic Coats disease, for example there is no sex and age preference, more bilateral cases, more severe cases and more genetic factors involved. Patients of Coats-like retinopathy with RP and FSHD may have mutations in Crumbs homologue gene 1 and D4Z4 genes.

Febrile seizures ( FS ) is a common convulsive disorder in infants and young children. It is clinically classified into simple febrile seizures(SFS)and complex febrile seizures(CFS). Although intensively investigated,it remains controversial on the etiology,pathogenesis,treatment,long-term prognosis of FS,even the definition itself is still under debate. This paper briefly reviews recent advances on the underlying mechanisms of FS,including involvement of genetic factors,role of ion channels,and immunologic and neurotransmitter dysreg-ulation. We also gathered some new insights on the treatment and prevention of FS,aiming to improve our under-standing of FS.

Objective To evaluate the short-term effect of open and laparoscopic cholecystectomy surgery on body.Methods Forty patients with cholecystectomy were divided into open surgery group and laparoscopic surgery group by random digits table method with 20 cases each.The clinical index was compared between two groups.The immunoglobulin G(IgG) and procalcitonin (PCT) before surgery and 4 d after surgery were determined.Results The operative blood loss,anal exhaust time,length of stay was (135.80 ±26.74) ml,(1.6 ±0.9) h,(6.7 ±3.2) d in open surgery group,which was better than that in laparoscopic surgery group [(63.41 ± 15.06) ml,(0.4 ± 0.3) h,(2.8 ± 1.9) d],and there was significant difference (P ＜ 0.05).The incidence of heat was 15％(3/20) in open surgery group,which was higher than that in laparoscopic surgery group (0),and there was significant difference (P ＜0.05).There was no significant difference in the IgG and PCT between two groups before surgery (P ＞ 0.05).The IgG and PCT at 4 d after surgery was (13.93 ± 1.98) g/L,(2 153.2 ± 1 452.1) mg/L in open surgery group,which was higher than that in laparoscopic surgery group[(9.23 ± 2.87) g/L,(768.0 ± 237.0) mg/L],and there was significant difference (P ＜ 0.05).Condmion Laparoscopic cholecystectomy has smaller short-term effects on body,while the body of the humoral and cellular immune function in mild,conducive to the body's recovery.

Objective:To construct Cyanovirin-N(CV-N) expression plasmid pET-CVN and express the protein in E.coli, and to prepare specific antibody against Cyanovirin-N.Methods:In this study, the encoding sequence of Cyanovirin-N was obtained by PCR. The expression plasmid pET-CVN was constructed by inserting the encoding sequence of CV-N into pET-His containing T7 promoter and then BL21(DE3)strain was transformed. Expression of CV-N was induced by IPTG at 30℃ for 8 h. Cyanovirin-N was refolded by using dialysis method. The target protein was purified through Ni2+-NTA Agarose Fast Flow. The purified Cyanovirin-N was used as an antigen to immunize rats,and the polycolonal antibody to Cyanovirin-N was obtained.Results:Cyanovirin-N was cloned and expressed in E.coli successfully. SDS-PAGE analysis showed that the Cyanovirin-N was expressed in the form of insoluble inclusion body,and the expression amount of Cyanovirin-N was about 42.08% of total protein. With ELISA detection the titer of antibody was more than 1∶8 000, Western blot analysis showed that the antibody can bind with Cyanovirin-N specifically.Conclusion:Cyanovirin-N expression plasmid pET-CVN has been constructed, Cyanovirin-N with bioactivity has been obtained. The prepared antibody against Cyanovirin-N has well specificity and reactivity and can be used to detect the expression products by recombinant strains of E.coli.The work lays a foundation further study of its functions.

The reconstruction with harmstring tendons is the commonly therapic method for the anterior cruciate ligament (ACL) injury. The graft-implant fixation is important for the initial biomechanics stability and the graft-tunnel healing. The methods of fixation are variable, which can be classified by direct fixation and indirect fixation or by in-tunnel fixation and non-in-tunnel fixation. The interface screw, endobutton, cross pin and tendon knot are most commonly used in clinic. No fixation method is superior to all others, for every method has advantages and disadvantages respectively.

Objective To evaluate the dynamic MR imaging findings of peripheral cholangiocarcinoma (PCC) of the liver. Methods Seventeen patients with PCC underwent dynamic MRI during the early, middle, and delayed phase after contrast medium administration. Enhancement pattern of the tumor, the wedge-like enhancement area peripheral to the tumor, dilatation of the intrahepatic biliary ducts, vascular involvement, and extrahepatic tumor invasion were evaluated. Results Early peripheral enhancement with progressive and concentric filling by contrast medium was the most frequent enhancement pattern (9 patients). A wedge-like enhancement area was observed in 10 patients. Ductal dilatation was found in 11 patients. Vascular involvement and extrahepatic invasion were seen in 8 and 2 patients, respectively. Conclusion Enhancement pattern is relative to the character of pathology (quantity and distribution of cell and fibrosis). Early peripheral enhancement with progressive and concentric filling by contrast medium may be specific for PCC.
