There are more than 70 species of flaviviruses, including Zika virus, Dengue virus and Japanese encephalitis virus, and more than 33 species are known to be capable of infecting humans. Only three flavivirus vaccines have been approved, and there is a lack of safe and effective vaccines for most flaviviruses. Adenovirus-vectored vaccines have high safety, low cost, and convenience to store and transport. Currently, two adenovirus-vectored Zika vaccines are under early clinical trials, and adenovirus-vectored vaccines for Dengue virus, Japanese encephalitis virus, West Nile virus and yellow fever virus are still in the phase of animal experiment. In the development of adenovirus-vectored flavivirus vaccines, there are still problems of pre-existing immunity to adenovirus, the insufficient immunogenicity of adenovirus vectors and the antibody-dependent enhancement effects among flavivirus. Based on relevant publications from January 2006 to June 2023, this article reviews the current status, challenges and solutions of the research into adenovirus-vectored flavivirus vaccines, so as to provide the reference for the development of relevant vaccines.

The hemodynamic effects of deliberated hypotension induced by PGE1 or SNP on 14 dogs anesthetized by ketamine were studied separately.MAP was decreased by 30%~40% after infusing PGE,or SNP Hemodynamic variables were measured before and 15 min 30 min after hypotension and 15 min after the discontinuation of infusion.The results indicated that SVRI, PVRI, MPAP, LVSWI and RVSWI all decreased significantly during PGE1-or SNP-induced hypotension. CVP decreased and HR increased significantly during SNP-induced hypotension, but with no significant change during PGE1-induced hypotension and with SVI. CI. PCWP remained unchanged in these two groups throughout the experiments.

Objective To study the causes, clinical feature,diagnoses and prognosis of pseudoprecocious puberty. Methods Thirty-eight cases with pseudoprecocious puberty were diagnosed by the serum LH and FSH of GnRHa stimulation test, pelvic ultrasonography and bone age assessment; they were treated and followed up. Results Peaks of LH were(0.49?0.48) IU/L, peaks of FSH were(0.54?0.78) IU/L, the level of E2 in 26 cases increased (36.11?15.70) ng/L,17-hydroxyprogesterone of 1 case was beyond 266 nmol/L. All cases showed hysterauxesis (3.98?1.18) mL. Cases of wrong contraceptive intake were 29,5 cases of McCune-Albright syndrome,2 cases of ovarian cyst, 1 case of ovarian granular cell tumor,1 case of congenital adrenal hyperplasia. Conclusions The causes of pseudoprecocious puberty are multifactors. Early diagnosis,therapy,follow-up are very important for prognosis.

OBJECTIVESince glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common hereditary hemolytic erythrocyte enzyme deficiency, most cases have single nucleotide mutations in the coding region, and current test methods for gene mutation have some missed detections, this study aimed to investigate the feasibility of RT-PCR sequencing in the detection of gene mutation in G6PD deficiency.

METHODSAccording to the G6PD/6GPD ratio, 195 children with anemia of unknown cause or who underwent physical examination between August 2013 and July 2014 were classified into G6PD-deficiency group with 130 children (G6PD/6GPD ratio <1.00) and control group with 65 children (G6PD/6GPD ratio≥1.00). The primer design and PCR amplification conditions were optimized, and RT-PCR sequencing was used to analyze the complete coding sequence and verify the genomic DNA sequence in the two groups.

RESULTSIn the G6PD-deficiency group, the detection rate of gene mutation was 100% and 13 missense mutations were detected, including one new mutation. In the control group, no missense mutation was detected in 28 boys; 13 heterozygous missense mutations, 1 homozygous same-sense mutation (C1191T) which had not been reported in China and abroad, and 14 single nucleotide polymorphisms of C1311T were detected in 37 girls. The control group showed a high rate of missed detection of G6PD deficiency (carriers) in the specimens from girls (35%, 13/37).

CONCLUSIONSRT-PCR sequencing has a high detection rate of G6PD gene mutation and a certain value in clinical diagnosis of G6PD deficiency.

OBJECTIVE: To investigate the feasibility and results of laryngeal functional preservation surgery for piriform sinus carcinoma with paraglottic space involvement. METHOD: Fourteen cases of piriform sinus carcinoma with paraglottic space involvement were reviewed. Laryngoplasty was performed after tumor was resected, bilater al selective neck dissections were performed at the same stage. Postoperative chemoradiotherapy was applied to 11 patients while the other 3 patients did not receive chemotherapy nor radiotherapy. The follow-up time ranged from 6 months to 5 years, and the mean follow-up time was three and a half years. RESULT: Twelve cases healed primarily while 2 cases experienced delayed heal because of pharyngeal fistula. Postoperative swallow bucking occurred in all patients, the longest gastric feeding time was 2 months. For the patients underwent postoperative chemoradiotherapy, the tumor did not recur in ten cases during the 3 years follow-up, while recurred in another case and the patient died without further treatment. Among those 3 cases without postoperative radiotherapy or chemotherapy, the tumor recurred in 2 cases during the following 6 months and chemoradiotherapy was applied, no recurrence presented in one patient, another one lost of follow-up. For the patient with recurred tumor 8 months after surgery, total laryngectomy was employed with postoperative chemoradiotherapy, the case died of tumor recurrence one and half year after the first surgery. The 3-year survival rate was 78.6%. For the vocal cord at lesion side, the mobility was noticeable in 6 patients, and visible anatomic landmark was lost in the other 8 patients. CONCLUSION Laryngeal function preservated surgery could be performed in selected cases of piriform sinus carcinoma with para-glottic space involvement in order to achieve better clinical results and quality of life.

OBJECTIVE:To explore the optimal steaming time of Carapax trionycis during cleansing period,and to optimize and improve production technology of Carapax trionycis recorded by current Chinese Pharmacopoeia. METHODS:The mechanical processing replaced the artificial processing method in Chinese Pharmacopoeia. The content of protein and the appearance of Cara-pax trionycis were investigated after steaming for 30,60,90,120,180,240 min during cleansing period. The extract,decoction, ash content,appearance and property of Carapax trionycis decoction piece processed with vinegar were also investigated after cleansed Carapax trionycis decoction piece was processed by sand scalding and vinegar quenching method. RESULTS:The differ-ent steaming time obtained different quality of cleansed Carapax trionycis decoction piece and Carapax trionycis decoction piece pro-cessed with vinegar. Compared with decoction piece steamed for other duration,when the steaming time was 90 min,the content of protein in cleansed Carapax trionycis decoction piece was higher(31.16%),and its appearance was up to the requirement. Cara-pax trionycis decoction piece processed with vinegar had higher contents of extract and decoction(9.13%,11.39%)and lower con-tent of ash(66.29%),and its appearance was up to the requirement. CONCLUSIONS:Different steaming time have certain effect on the quality of cleansed Carapax trionycis and Carapax trionycis processed with vinegar,the optimal steaming time of Carapax tri-onycis is about 90 min during cleansing. The mechanical processing method maybe replace the artificial processing on Carapax tri-onycis for improving its production efficiency.
