In recent years, the development of molecular biology and medicine has prompted the research of gene therapy for brain diseases. In this review, we summarized the current gene therapy approaches of major brain diseases. Against the pathogenesis of major brain diseases, including brain tumors, Parkinson's disease, Alzheimer's disease and cerebrovascular disorders, there are several effective gene therapy strategies. It is no doubt that, gene therapy, as a novel treatment, is of great significance for understanding the causes, as well as comprehensive treatment for brain diseases.

Background:Helicobacter pylori( Hp)is the main cause of chronic gastritis( CG),and CagA and VacA are important pathogenic factors of Hp. Recent studies have indicated that CagA and VacA antibodies of Hp have close relationship with gastric cancer(GC)and peptic ulcer(PU). Aims:To investigate the relationship between different antibodies of Hp and GC,PU and CG in Xinjiang area. Methods:Eighty-four GC,108 PU and 196 CG patients from Jan. 2014 to Aug. 2014 were enrolled. 14 C-urea breath test was used to determine Hp infection. Hp was typed by immunoblotting technique. Relationship between different Hp antibodies and patients with GC,PU and CG was analyzed. Results:Type Ⅰ Hp-positive rate in GC,PU and CG groups was decreased stepwisely(47. 6% ,37. 0% ,21. 4% , respectively). The positive rates of Hp strains(CagA-128 kDa,VacA-110 kDa and UreB-66 kDa)differed significantly among GC,PU,and CG groups(P = 0. 013,P = 0. 011,P = 0. 002);GC was associated with CagA-128 kDa,VacA-110 kDa,VacA-90 kDa and UreB-66 kDa(P < 0. 05),PU was associated with VacA-110 kDa,UreB-66 kDa(P < 0. 05). UreB-66 kDa was the risk factor of PU and GC(P < 0. 05). Conclusions:GC is associated with CagA-128 kDa,VacA-110 kDa,VacA-90 kDa and UreB-66 kDa,PU is associated with VacA-110 kDa,UreB-66 kDa,and UreB-66 kDa is the risk factor of PU and GC.

Objective To observe the influence of the insulation blanket applied in general anesthesia on the incidence of postoperative delirium.Methods 60 patients with elective laparoscopic cholecystectomy under generalanesthesia with ASA of grade Ⅰ-Ⅱ were selected.According to the random number table,the patients were divided into group A(without insulation blanket)and group B (with insulation blanket),each group in 30cases.The dosage and drug batch number of anesthetic drugs were same.Evaluated each patient using the confusion assessment method-chinese revised (CAM-CR).Recorded the number of cases of delirium for each group when 24 hours,48 hours, 72 hours after operation.Results The incidence of postoperative delirium in group A was 6.7%,which in group B was 0.0%.The incidence of postoperative delirium of group B was lower than group A (P <0.05 ).Conclusion Using insulation blanket to protect body temperature in perioperative operation can reduce the incidence of postopera-tive delirium in perioperative operation.

Objective To investigate the effect of N-methyl-N-nitrosourea (MNU) on expressions of interphotoreceptor retinoid-binding protein (IRBP) and recoverin in rat retinal.Methods Thirty female Sprague-Dawley (SD) rats were randomly divided into five groups,including normal control group,and MNU treatment one day,three days,seven days and 10 days groups,each group had six rats.Rats in MNU-treatment groups received a single intraperitoneal injection of 40 mg /kg MNU,while rats in the normal control group received intraperitoneal injection of saline 5 ml/kg.Reverse transcription-polymerase chain reaction (RT-PCR) and immunofluorescence were used to detect the retinal expression of IRBP and recoverin.Results RT-PCR results indicated that retinal IRBP levels decreased after MNU injection compared with normal control (P＜0.01),while recoverin levels increased (one day:P＞0.05; three days:P＜0.05; seven days:P＜0.5; 10 days:P＜0.05).Immunofluorescence assays demonstrated that normally IRBP protein is mainly in the inner and outer segments of photoreceptors.After MNU treatment,IRBP protein was detected in all retinal layers but much faint.Recoverin was expressed in the inner nuclear layer,inner plexiform layer and ganglion cell layer,and its expression was increased after MNU injection.Conclusion MNU suppresses IRBP expression and promotes recoverin expression in rat retina.

Objective To evaluate the method and result of thyroid artery embolization as a new therapy for hyperthyroidism. Methods Twenty two patients with hyperthyroidism underwent selective thyroid artery embolization. Totally 52 thyroid arteries were embolized with microspheres. The indications to this therapy were following: hyperthyroid patients having indications to surgical and 131 I therapy, clinically being difficult to complete the preparation for subtotal thyroidectomy and having high risk for surgical process because of their huge thyroid gland. Results Serum level of thyroid hormones dropped significantly [median T3 from 8 8 nmol/L(4 3～ 43 0 nmol/L) to 4 0 nmol/L(1 1～9 2 nmol/L), median T4 from 206 4 nmol/L(77 4～748 2 nmol/L) to 144 5 nmol/L(25 8～279 9 nmol/L), P

Objective To compare the clinical effect and adverse reactions of different concentrations of dezocine epidural anesthesia for cesarean section.Methods According to digital table,120 cases of elective cesarean section were randomly divided into 4 groups with 30 cases in each group, the group D1 was given with dezocine 2.5mg,the group D2 with dezocine 5mg,the group D3 with dezocine 10mg,the group M with morphine 2mg.All the drugs used in postoperative epidural analgesia after cesarean section.To observe resting pain and conduct the VAS scoring at postoperative 4,8,12,24h and record various adveme reactions.Results The VAS scores at postoperative 4,8,12h in the group D1 were lower than those in the D2,D3,M with statistical difference(all P<0.05).The VAS scores at postoperative 4,24h had no statistical difference among D2,D3,M groups(all P>0.05).The VAS scores at postoperative 8h in the group D3 were lower than those in the D2,D3,M with statistical difference(all P<0.05). There were no statistical differences among 4 groups at postoperative 24h(all P>0.05).The incidence rates of nause-a and vomiting the group M were higher than that in the group D1,D2 and D3,showing statistical difference among them(P<0.05).Conclusion Appropriate concentrations of dezocine used in postoperative epidural analgesia after cesarean section has definite effect and less adverse reactions.

Objective] To find a rapid method for diagnosing Acanthamoeba keratitis and identifing Acanthamoeba . [Methods] 10% potassium hydroxide(KOH) wet mount preparations, Acanthamoeba culture, inverted phase contrast microscopy,and pathological examination using H.E. staining and PAS staining. [Results]Using corneal scrapings and corneal materials obtained from surgery,7 cases and 5 cases of Acanthamoeba keratitis were diagnosed by 10% KOH wet mount preparations. 6 strains of Acanthamoeba were isolated in corneal materials of 6 cases by protozoa culture method. The cysts, trophozoites and pseudopods on the trophozoites of Acanthamoeba were directly observed under the inverted phase contrast microscope. The cysts and trophozoites of Acanthamoeba were seen by H.E. staining and PAS staining with 20 h. [Conclusion] Acanthamoeba keratitis could be rapidly diagnosed by 10% KOH wet mount preparations and inverted phase contrast microscopy. Acanthamoeba organisms could be directly observed and identified under inverted phase contrast microscope.

Objective To investigate the protective effect of mild hypothermia during cerebral ischemia and reperfusion. Methods After 3 hours of middle cerebral artery occlusion (MCAO) in rats, the myeloperoxi-dase (MPO) activity, the positive expression of intercellular adhesion molecule-1 (ICAM-1) , and the leukocyte integrin Mac-1 (CD11b/CD18) level in the ischemic regions were determined at different times (6 h,12 h,24 h, 48 h and 72 h) during and after 24 h of reperfusion. Cerebral infarction volume and neurological function were also evaluated in a control group, in addition to the above variables, at 24 hours of reperfusion. Results The MPO activity and the expression of ICAM-1 and Mac-1 were significantly elevated at 6 h after cerebral ischemia during reperfusion. These variables peaked at 48 h. There was a remarkable difference between the various groups and a sham-operated group ( P
