National Journal of Andrology 2015;21(11):1001-1004
OBJECTIVETo explore the genotypes of human papilloma virus (HPV) in male patients with condyloma acuminate in Lishui area of Zhejiang Province, China.
METHODSUsing HybriMax, we identified the genotypes of HPV of the verruca samples from 110 male condyloma acuminate patients aged 16 - 65 years in Lishui area.
RESULTSHPV infection was detected in 107 (97.27%) of the condyloma acuminate patients, including 76 cases (71.02%) of simple infection and 31 cases (28.97%) of multiple infection. The peak age of infection was 21 - 40 years old. Totally, 14 genotypes of HPV were identified, including the high-risk genotypes as HPV16, 53, 52, 33, CP8304, 58, 51, 45, 66, 68, and 59, which accounted for 44.85% of the cases, and the low-risk ones as HPV6, 11, and 19 (43), with an infection rate of 93.45%.
CONCLUSIONThe low-risk genotype is a dominant type of HPV infection and the rates of high-risk genotype and multiple infection are high among the male condyloma acuminate patients in Lishui area.

Abstract: Objective To explore the clinical characteristics of nucleic acid negative newborns delivered by pregnant women infected with SARS-CoV-2 (Omicron variant BA. 5.1.3) in Sanya area, and to provide evidence for understanding its clinical characteristics. Methods A retrospective analysis was performed on 14 neonates with negative nucleic acid delivered by pregnant women who tested positive for SARS-CoV-2 (Omicron variant BA.5.1.3) in Sanya Central Hospital (the Third People's Hospital of Hainan Province) from June 2022 to September 2022 (observation group, n=14). The corresponding nucleic acid-negative newborns delivered by pregnant women detected negative with SARS-CoV-2 (Omicronon variant strain BA.5.1.3) were set as the control group (n=56), and the general data and clinical characteristics of neonates in the two groups were compared. Results There was no significant difference between the observation group and the control group in pregnancy diabetes, pregnancy induced hypertension, gestational pre-eclampsia, fetal intrauterine distress, premature rupture of membranes (P>0.05); there was no significant difference between the observation group and the control group in terms of sex, gestational age, birth weight, age, mode of delivery, birth Apgar score, heart screening, pulmonary disease, glucose 6-phosphate dehydrogenase (G6PD) deficiency, thalassemia, breast milk jaundice, hemolytic jaundice (P>0.05). The bilirubin level, blue light irradiation cases and the duration of blue light irradiation of the newborns in the observation group at 7 days after birth were higher than those in the control group (P<0.05); the ratio of blood oxygen saturation ≥ 90% in the observation group was lower than that in the control group (21.43% vs 89.29%, P<0.05), and the ratio of blood oxygen saturation occasionally<90% was higher than that in the control group (57.14% vs 10.71%, P<0.05). The ratio of blood oxygen saturation<90% had no significant difference compared with that in the control group (7.14% vs 0, P>0.05), and the ratio of blood oxygen saturation reduced to the required oxygen uptake was higher than that in the control group (14.29% vs 0, P<0.05). Conclusions The jaundice manifestation of the nucleic acid-negative newborns delivered by pregnant women infected with SARS-CoV-2 (Omicronon variant strain BA.5.1.3) in Sanya area is relatively obvious, with blood oxygen saturation easily lower than 90% and even requiring oxygen inhalation in severe cases.

OBJECTIVESTo establish a transplanted tumor producing HCV NS3 protein in mice and study the therapeutic effect of minigene vaccine based on invariant chain substitution.
METHODSSP2/0-NS3 cells expressing HCV NS3 antigen were injected subcutaneously into BALB/ c mice. After three days of inoculation, different therapeutical reagents were injected intramuscularly into different groups of mice. The boost immunization was carried out two weeks after the first immunization. The efficiency of HCV NS3 Th1 minigene vaccine was estimated after 60 days observation.
RESULTSFor saline, pCI-neo, pHCV-NS3 and pHCV-NS3-Th1 treated groups, the induction period needed for tumor growth was 16.17+/-2.55, 14.40+/-1.82, 16.75+/-2.36, and 24.00+/-5.57 days (t =2.623, P =0.034 vs saline, t =3.713, P =0.010 vs pCI-neo and t =2.425, P =0.045 vs pHCV-NS3) respectively. The tumorigenesis rates were 100%, 100%, 57.1% (8/14, chi2 = 6.190, P = 0.013 vs saline and chi2 = 6.608, P = 0.010 vs pCI-neo) and 46.7% (7/15, chi2 = 9.707, P = 0.002 vs saline and chi2 = 10.311, P = 0.001 vs pCI-neo ) respectively. The survival rates were 0, 0, 50.0% (7/14, chi2 = 5.787, P = 0.016 vs saline and chi2 = 9.333, P = 0.002 vs pCI-neo) and 53.3% (8/15, chi2 = 6.651, P = 0.010 vs saline and chi2 = 10.311, P = 0.001 vs pCI-neo) respectively. The average tumor diameter of the pHCV-NS3-Th1 treated group was significantly smaller compared with the control groups and the pHCV-NS3 treated group (P =0.001). Moreover, the average survival time of tumor-bearing mice immunized with pHCV-NS3-Th1 was 6 days longer compared with the saline treated group, 12 days longer compared with the pCI-neo treated group (P =0.001), and 6 days compared with the pHCV-NS3 treated group.
CONCLUSIONHCV NS3 Th1 epitope vaccine might be a potential biotherapy candidate against HCV infection.

OBJECTIVETo investigate the immunogenicity of HIV vaccine vTKgpe based on Vaccinia Virus Tiantan vector in mice and rabbits.
METHODSMice were inoculated with HIV vaccine vTKgpe by intramuscular (i.m.), intradermal (i.d.) or subcutaneous (s.c.) injections. Blood sample were collected every week, and then antibodies against HIV and vaccinia virus vector were detected. At week 4, some mice were killed and cellular immune responses were examined by flow cytometer. Additionally two rabbits were vaccinated subcutaneously, blood sample were tested as done with mice.
RESULTSIn mice i.m. and s.c. groups, HIV specific antibodies emerged at week 2 and declined at week 4. Antibodies against vector elevated rapidly at week 4, and potentially affected HIV specific antibody detection. Cellular immune responses were only detected in s.c. group. Serum of rabbit showed that anti-HIV antibody appeared at week 2 and maintained for several weeks.
CONCLUSIONVaccine vTKgpe innoculated by i.m. and s.c routes inclined to induce humoral immune responses in mice, but in i.d. group, inclined to induce cellular immune responses. Response to the recombinant vaccinia virus was more sensitive in rabbit than in mice.

OBJECTIVETo explore the prognostic factors of anorectal malignant melanoma (ARMM).
METHODSMedical records and follow-up data of 34 patients with ARMM treated in the Chinese PLA General Hospital from March 1993 to November 2011 were analyzed retrospectively.
RESULTSThere were 26 abdominoperineal resections(APR) and 8 wide local excisions (WLE). Twenty patients underwent postoperative adjuvant therapy, including chemotherapy in 14 cases, radiotherapy in 2 cases, traditional Chinese medicine therapy in 4 cases and immunotherapy in 16 cases. Postoperative follow-up was carried out in all the patients and the mean follow-up period was 27 months. The 1-, 3- and 5-year overall survival rates were 76.3%, 39.6% and 20.6% respectively, while the 1-, 3- and 5-year disease-free survival rates were 60.6%, 30.8% and 12.8% respectively. APR and postoperative immunotherapy could significantly reduce the local recurrence rate. According to the Kaplan-Meier method, gross type of tumor, mural involvement, lymph metastasis, and clinical staging had significant effects on overall survival, while lymph metastasis and postoperative immunotherapy on disease-free survival. Cox proportional hazards model indicated that the clinical staging and postoperative immunotherapy were significant predictive factors.
CONCLUSIONSEarly diagnosis and correct choice of surgical method are the keys to the treatment. Postoperative immunotherapy can prolong disease-free survival.

OBJECTIVETo observe the effect of a Chinese medicine compound, Naoerkang (NEK), on amyloid-beta peptide (1-42; Aβ(1-42)) and matrix metalloproteinase-9 (MMP-9) expressions in the hippocampus of Alzheimer's disease (AD) model rats.
METHODSA total of 48 male Sprague Dawley (SD) rats were randomly divided into normal control, untreated, and piracetam groups, and low-dose, medium-dose, and high-dose NEK groups, with 8 rats in each group. The 5-μL aggregated Aβ(1-42) (2 μg/μL) were injected into both CA1 areas of the hippocampus in the rats to establish an AD model, whereas the normal control was treated with the same dose of normal saline. The rats in the NEK groups were treated with a high, medium, or low dose of NEK [60 g/(kg·d), 30 g/(kg·d), and 15 g/(kg·d)], respectively, intragastrically for 28 days; piracetam (0.375 g/kg, intragastrically) was consecutively administered in the piracetam group; and normal saline was applied in the normal control and untreated groups. A Y-maze test was used for behavioral study to test the learning and memory abilities. Aβ(1-42) and MMP-9 expressions in the hippocampus was determined immunohistochemically, and the results were analyzed by image acquisition and an analysis system.
RESULTSAggregated Aβ(1-42) induced obvious learning and memory dysfunction, as well as up-regulation of Aβ(1-42) expression in the hippocampus. Compared with those in the normal control group, the learning and memory abilities of rats in the untreated group significantly decreased (P<0.01), and the expression of Aβ(1-42) was significantly increased (P<0.01). Twenty-eight days after different treatments, compared with those in the untreated group, the learning and memory abilities of AD model rats in the piracetam, low-dose, medium-dose and high-dose NEK groups were significantly improved (P<0.01 or P<0.05), and the expression of Aβ(1-42) in the hippocampus decreased (P<0.01 or P<0.05), and MMP-9 increased (P<0.01 or P<0.05), especially in the high-dose NEK group.
CONCLUSIONNEK might play a role of anti-dementia by increasing the expression of MMP-9 in the hippocampus of AD model rats, resulting in the reduction of the quantity of Aβ(1-42) and improvement in learning and memory ability in AD model rats.
