The full length cDNA of silkworm hibadh gene was cloned by RT-PCR and RACE (Rapid amplification of cDNA ends) technique. The hibadh gene and its deduced amino acid sequences were analyzed. The tissue distribution of hibadh gene in 5th instar silkworm larvae was tested by RT-PCR. The expression patterns of hibadh gene in simulated weightless environment were analyzed by real time RT-PCR. The results showed that the full length hibadh cDNA sequence was 1074 bp in lenth, including an open read frame of 969 bp encoding the entire coding region of Hibadh (GenBank accession No. EU719652). The deduced amino acid sequence similarities of hibadh between silkworm and Burkholderia ambifaria, Drosophila melanogaster, Apis mellifera, Xenopus tropicalis, Mus musculus, Homo sapiens were 46%, 43%, 48%, 44%, 45%, 45%, respectively. Signal peptide analysis showed that Hibadh was a secretory protein. There wasn't glycosyl-phosphatidyl inositol anchor site in Hibadh amino acid sequence. Molecular weight and isoelectric point of Hibadh were 34.1 kD and 9.14 respectively. The RT-PCR tests indicated that the hibadh gene expressed in head, silk gland, midgut, cuticle, blood, fat body, tuba malpighii of the 5th instar silkworm larvae. There were different expression patterns of hibadh gene during different silkworm embryo period in simulated weightless environment. Simulated weightlessness resulted in the expression of silkworm hibadh gene up regulated 2.3-fold (P < 0.05), up regulated 4.6-fold (P<0.01), down regulated 7.6-fold (P < 0.01), down regulated 2.6-fold (P < 0.05) during apophysis formation period, inverse period, trachea formation period, and whole embryo period, respectively. There was no significant change of hibadh gene expression during other period of silkworm embryo between simulated weightless and control groups. There were different response patterns to simulated weightless environment between hibadh gene and whole body of silkworm. Gene showed much higher sensitivity compared to whole body in response to environment. This study is useful for the further research on the gravity biological mechanism of hibadh gene.

Objective:To analyze the clinical characteristics of nephrogenic adenoma of the bladder.Methods:The clinical and pathological data of 8 patients with bladder nephrogenic adenoma, during the period from July 2016 to June 2019, were retrospectively analyzed. Patients’ age were 33 to 71 years old and the average age was 55, including 5 males and 3 females. The clinical manifestations were hematuria in 7 cases, urinary tract irritation in 6 cases, and no obvious symptoms in 1 case. There were 7 cases with cystitis, 3 cases with urolithiasis, 2 cases with bladder cancer, 1 case with invasive colonic mesentery fibroma, and 1 case without other complications. 5 cases had the history of urological operation. The predilection site was the lateral wall with 5cases; 5 cases were solitary; the average maximum diameter of the tumor was 0.9 cm (range 0.1-1.8 cm). Under cystoscope, papillary mass can be seen, the surface is bright red, the pedicle is not obvious, the papilla is thick and short, easy to bleed when touching; some of them are scattered and lichen like changes. All patients received transurethral resection of bladder mucosa.Results:Pathological examination shows that the bladder mucosa showed chronic inflammation, interstitial edema, granulation tissue hyperplasia, eosinophil infiltration and metaplasia of mesonephroid epithelium. All of the 8 patients were followed up by telephone for 2 to 38 months, with an average of 17.1 months. So far, neither recurrence has been detected.Conclusions:The diagnosis of nephrogenic adenoma of the bladder depends on pathological examination. It must be totally removed during operation. The recurrence and malignancy should be treated in time after operation.
