ABSTRACT

BACKGROUND: The purpose of this analysis is to evaluate the current evidence with regard to the effectiveness and safety between coiling and clipping in patients with ruptured intracranial aneurysms (RIAs). METHODS: We performed a meta-analysis that compared clipping with coiling between July 2000 and September 2021. PubMed, EMBASE, and the Cochrane Library were searched for related articles systematically. And the treatment efficacy and postoperative complications were analyzed. RESULTS: We identified three randomized controlled trials and thirty-seven observational studies involving 60,875 patients with ruptured cerebral aneurysms. The summary results showed that coiling was related a better quality of life (mRS0-2; OR=1.327; CI=1.093-1.612; p<0.05), a higher risk of mortality (OR=1.116; CI=1.054-1.180; p<0.05), higher rate of rebleeding (RR=1.410; CI=1.092-1.822; p<0.05), lower incidence of vasospasm (OR=0.787; CI=0.649-0.954; p<0.05), higher risk of hydrocephalous (RR=1.143; CI=1.043-1.252; p<0.05), lower risk of cerebral infarction (RR=0.669; CI=0.596-0.751; p<0.05), lower risk of neuro deficits (RR=0.720; CI=0.582-0.892; p<0.05), and a lower rate of complete occlusion (OR=0.495; CI=0.280-0.876; p<0.05). CONCLUSION: Coiling was significantly associated with a better life quality (mRS0-2), a lower incidence of postoperative complications, and a higher rate of mortality, rebleeding, hydrocephalous, and a lower rate of complete occlusion than clipping.

ABSTRACT

BACKGROUND: The supraorbital keyhole approach (SKA) and pterional approach (PA) have been recommended for clipping intracranial aneurysms (IAs). We conducted a meta-analysis to systematically and comprehensively compare the clinical outcomes between the 2 approaches. METHODS: We retrieved potential academic studies that had compared the clinical outcomes of SKA and PA for clipping IAs from the Cochrane Library, Medline, PubMed, and EMBASE databases. The references of the identified studies were carefully reviewed to ensure that all available documents had been included in the present study. The meta-analysis was conducted in accordance with the acknowledged PRISMA (prioritized reported items for systematic review and meta-analysis) guidelines. RESULTS: A total of 8 studies with 1016 participants were included in our study. Of these 1016 patients with IAs, 518 were assigned to the SKA group and 498 to the PA group. Our results showed that the SKA is preferable for clipping IAs compared with the PA because of its shorter operative time (weighted mean difference, -3.163; 95% confidence interval [CI], -5.577 to -0.749; P = 0.01) and length of stay, especially for the patients with unruptured IAs (weighted mean difference, -52.107; 95% CI, -81.597 to -22.618). However, a lower risk of postoperative infection was found in the SKA group (4.6% vs. 8.5%; odds ratio, 0.398; 95% CI, 0.186-0.850; P = 0.017), which seemed to derive from the ruptured IAs (OR, 0.330; 95% CI, 0.136-0.800; P = 0.014). However, no significant difference was found in the incidence of frontal sinus opening, completed occlusion, procedural complications, intraoperative rupture, postoperative hematoma, or cerebral vessel spasm. CONCLUSIONS: The SKA was associated with a shorter length of stay and operation time and a lower risk of postoperative infection. Hence, the SKA seems to be equally effective and safe for clipping IAs compared with PA and should be recommended for surgeons who have acquired sufficient experience with this technique owing to its advantages compared with the PA.

ABSTRACT

OBJECTIVE: To construct and research the expression of the recombinant plasmid pGEX-Sj14-3-3 in Escherichia coli BL21 (DE3). METHODS: Sj14-3-3 gene was amplified by RT-PCR from template of the total RNA extracted from adult worms of S. japonicum, and then cloned into the vector pGEX-1gammaT to construct pGEX-Sj14-3-3. The recombinant plasmid pGEX-Sj14-3-3 was transformed into E. coli BL21 (DE3). BL21 (pGEX-Sj14-3-3) was induced with isopropyl-beta-D-thiogalactopyranosid (IPTG), and the expressed products were identified by SDS-PAGE and Western blot. RESULTS: A 399 bp fragment of Sj14-3-3 coding gene was successfully amplified by RT-PCR and cloned into the vector pGEX-1gammaT, and the recombinant plasmid pGEX-Sj14-3-3 was constructded successfully. The molecular mass of the expressed recombinant protein was proximately 40 000 Dolton as detected by SDS-PAGE. The amount of the expressed protein was about 21% of the total bacterial protein. Western blot confirmed that the expressed protein could be recognized by the immune sera from rabbit infected with Schistosoma japonicum. CONCLUSION: The recombinant plasmid pGEX-Sj14-3-3 was successfully constructed. The Sj14-3-3 protein was highly expressed in E. coli and the expressed recombinant protein possessed specific antigenicity.

ABSTRACT

OBJECTIVE: To study the feasibility of rSj26GST-Sj32-IgG-ELISA for diagnosis of chronic schistosomiasis japonicum. METHODS: The Escherichia coli BL21 (DE3) with recombinant plasmid pET32alphaSj26GST-Sj32 were induced with isopropy-beta-D-thiogalactopyranosid (IPTG), and the expression product was analyzed by SDS-PAGE and purified by Ni-NTA kits. Schistosoma japonicum (Sj) adult worm antigen(SjAWA) was produced by routine method. The IgG antibodies were detected with the sera of chronic schistosomiasis japonicum by ELISA using recombinant Sj26GST-Sj32 (rSj26GST-Sj32) fusion protein and SjAWA, while the controls included the sera of patients with clonorchiasis, paragonimiasis westermani, alveolar echinococcosis, cystic echinococcosis, hepatitis B, pulmonary tuberculosis and healthy people. RESULTS: The sensitivity and specificity of rSj26GST-Sj32 fusion protein were 95.00% (38/40) and 97.67% (42/43) respectively, they were 92.50% (37/40) and 97.67% (42/43) respectively in SjAWA groups. There were no difference in sensitivity and specificity between rSj26GST-Sj32 and SjAWA (P > 0.05). There were different cross reactions in clonorchiasis sinensis and paragonimiasis westermani between the two methods. The cross reaction with SjAWA was 20.00% (2/10) in patients with alveolar echinococcosis, but no cross reaction with rSj26GST-Sj32 (P > 0.05). CONCLUSION: rSj26-Sj32-IgG-ELISA probably could be applied to immunodiagnosis for chronic schistosomiasis japonicum.

ABSTRACT

OBJECTIVE: To study the diagnostic value of the Dot ELISA with rSj26-Sj32 fusion protein for chronic schistosomiasis japonica. METHODS: rSj26-Sj32 fusion protein and SjAWA were used to establish the HRP-IgG-Dot-ELISA. Serum samples from patients with chronic schistosomiasis japonica (40 cases), clonorchiasis sinensis (21 cases), paragonimiasis westermani(13 cases), alveolar echinococcosis (10 cases), cystic echinococcosis(9 cases), hepatitis B(20 cases), pulmonary tuberculosis (20 cases) and healthy persons (43 cases) were examined. RESULTS: Sensitivity and specificity were respectively 92.5% (37/40) and 95.4% (41/43) for rSj26-Sj32-Dot-ELISA and 95.0% (38/40) and 93.0% (40/43) for SjAWA-Dot-ELISA, and there was no significant difference between two antigens (P > 0.05). There were different cross reactions to the sera of patients with clonorchiasis sinensis, paragonimiasis westermani or alveolar echinococcosis, but no cross reaction to the sera of patients with cystic echinococcosis, hepatitis B or pulmonary tuberculosis. The positive and negative predictive value and efficiency of diagnosis of rSj26-Sj32-Dot-ELISA for chronic schistosomiasis japonica were 84.1% (37/44), 97.7% (129/132), and 94.3% (166/176), respectively, and those of SjAWA-Dot-ELISA were 77.6% (38/49), 98.4% (125/127), and 92.6% (163/176), respectively. There was no significant difference between the two methods (P > 0.05). CONCLUSION: rSi26-Si32 fusion protein can be applied to immunodiagnosis for chronic schistosomiasis japonica.

ABSTRACT

AIM: To study whether rSj26-Sj32 fusion protein can be used for diagnosis of chronic schistosomiasis japonicum. METHODS: ELISA, Dot-ELISA and dipstick were performed to detect the IgG in the sera of patients with chronic schistosomiasis japonicum using the antigens of rSj26-Sj32 fusion protein and SjAWA. The control sera were taken from health donors and the patients with clonorchiasis sinensis, paragonimiasis westermani, alveolar echinococcosis and cystic echinococcosis. RESULTS: The sensitivity of the three methods was 95.00%, 92.50% and 92.50% respectively, whereas the specificity of the three methods was 97.67%, 95.35% and 97.67%, respectively. CONCLUSION: The rSj26-Sj32 fusion protein has therapeutic potential for immunodiagnosis of chronic schistosomiasis japonicum.
