A 460 bp internal fragment of the AcrA gene from Vibrio alginolyticus strain HY9901 was amplified by PCR with designed primers and the unknown flanking sequence of 5 '- and 3 '- ends of the AcrA gene was finally characterized by inverse PCR and nested PCR. Sequence analysis showed the AcrA gene contained 1101 bp ORF encoding 366 amino acids and the deduced amino acid sequence of the precursor from Vibrio alginolyticus strain HY9901 showed significant homology with the putative protein of other Vibrio species. The AcrA shows 76%, 73%, 71% and 70% homology with V.vulnificus strain YJ016, V. parahaemolyticus strain RIMD 2210633, V. splendidus strain 12B01 and V. cholerae O1 biovar eltor str. N16961 respectively.

OBJECTIVE:To observe therapeutic efficacy and safety of Yinxing damo injection for neural function recovery af-ter hypertensive intracerebral hemorrhage (HICH) minimally invasive surgery. METHODS:84 HICH patients were randomly di-vided into control group and observation group with 42 patients in each group. Both groups received CT guiding minimally inva-sive aspiration. Control group was given western medicine baseline therapy,such as dehydration and intracranial decompression, controlling blood pressure,preventing infection,alimenting never,symptomatic treatment. Observation group was additionally giv-en Yinxing damo injection 20 ml,ivgtt,bid. Treatment course lasted for 14 d. NIHSS score,GCS score and Fugl-Meyer motor function assessment scale score were comducted before and after treatment. The serum levels of NSE,serum C3,C4 and hs-CRP were determined in 2 groups before and after treatment. RESULTS:After treatment,the effective rate of observation group (85.71%)was better than that of control group(66.67%),with statistical significance(P<0.05);after treatment,NIHSS score, Fugl-Meyer score and GCS score of 2 groups were all better than before,the observation group was better than the control group, the levels of C3 and C4 in observation group were lower than in control group,with statistical significance(P<0.01). There was one case of allergic reaction that the patient can tolerate. Magnesium sulfate for external use was given,which did not affect the treatment. CONCLUSIONS:Yinxing damo injection could improve neurologic impairment,promote the recovery of patients and have good safety.

Objective To investigate the effects of Ulinastatin(UTI)on the function of splenic lymphocytes from rats with severe acute pancreatitis(SAP).Method Twenty-eight Wister rats(clean grade)were randomly divided into control,sham operation,SAP,and ulinastatin group.No operation was performed in control group.And rats with sham-operation received laparotomy and catheterization into choledocho-pancreatic duct without injection of sodium deoxycholic.Rats in ulinastatin group received ulinastatin injection(50000 U/kg)via tail vein 30 minutes after pancreatitis induced with DCA injected into pancreatic duct.Rats ofother groups were given equal volume of saline.At 2,4 hours after operation,all animals were killed by neck dislocation,and splenocytes were isolated and cultured in RPMI 1640 medium containing 10%fetal calf serum.Proliferation of splenecytes was determined with MIT cellular proliferation assay.Levels of Th1 cytokines(IL-2,IFN-γ)and Th2 cytokine(IL-10)in supematants of splenoeytesweremeasured by ELISA.Quantitative data were expressed as mean±SE.Statistical analyses were performed by Student's t test with SPSS software(version 10.0 for Windows).A P value less than 0.05 Was considered statistically significant. Results The concentration of IL-2, IL-10 and IFN-γ and proliferative activity of splenocytes in SAP group were significantly lower than that in sham operation group.In contrast,the proliferative as well as the eytokine-releasing capacities of the solenecms from rats treated with UTI were significantly increased compared with those from rats with SAP.Conclusions The deficiencies in proliferation and cytokine release in response to antigen stimulation inaplys an anergic state of splenocytes during SAP.Treatment with UTI contributed to the recovery of the immune function by improving proliferative responses and cytokine release of splenocytes.

Purpose: Neoadjuvant therapy modality can increase the operability rate and mitigate pathological risks in locally advanced cervical cancer, but treatment response varies widely. It remains unclear whether genetic alterations correlate with the response to neoadjuvant therapy and disease-free survival (DFS) in locally advanced cervical cancer. Materials and Methods: A total of 62 locally advanced cervical cancer (stage IB-IIA) patients who received neoadjuvant chemoradiation plus radical hysterectomy were retrospectively analyzed. Patients’ tumor biopsy samples were comprehensively profiled using targeted next generation sequencing. Pathologic response to neoadjuvant treatment and DFS were evaluated against the association with genomic traits. Results: Genetic alterations of PIK3CA were most frequent (37%), comparable to that of Caucasian populations from The Cancer Genome Atlas. The mutation frequency of genes including TERT, POLD1, NOS2, and FGFR3 was significantly higher in Chinese patients whereas RPTOR, EGFR, and TP53 were underrepresented in comparison to Caucasians. Germline mutations were identified in 21% (13/62) of the cohort and more than half (57%) had mutations in DNA damage repair genes, including BRCA1/2, TP53 and PALB2. Importantly, high tumor mutation burden, TP53 polymorphism (rs1042522), and KEAP1 mutations were found to be associated with poor pathologic response to neoadjuvant chemoradiation treatment. KEAP1 mutations, PIK3CA-SOX2 co-amplification, TERC copy number gain, and TYMS polymorphism correlated with an increased risk of disease relapse. Conclusion We report the genomic profile of locally advanced cervical cancer patients and the distinction between Asian and Caucasian cohorts. Our findings highlight genomic traits associated with unfavorable neoadjuvant chemoradiation response and a higher risk of early disease recurrence.
