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.

Irreducible anteromedial radial head dislocation (IARHD) caused by transposed biceps tendon is rare. Delayed diagnosis and surgical failure often occur. A 46-year-old fisherman presented with 10 days history of painful swelling and restricted movement of his right elbow due to strangulation injury by a fishing boat cable. On examination, the images of the right elbow reveals in a "semi-extended and pronated" elastic fixation position. Radiography and 3-dimensional reconstruction CT reveals an isolated anteromedial radial head dislocation with extreme protonation of the radius and the bicipital tuberosity towards the posterior aspect of the elbow joint, and MRI shows biceps tendon wrapping around the radial neck, similar to umbilical cord wrapping seen in newborns. The Henry approach was applied for the first time to reduce the biceps tendon. The patient achieved a good functional recovery at 26 months, which represents the first reported case of IARHD without fracture caused by biceps tendon in an adult. In treatment of IARHD, attention should be paid to the phenomenon of biceps tendon transposition. Careful clinical examination, comprehensive imaging modalities, and appropriate surgical approach are the keys to successful management.

OBJECTIVETo objectively assess the clinical efficacy and safety of a new Pulian Ointment (, NPLO) in treating psoriasis of blood-heat syndrome of Chinese medicine.

METHODSA total of 108 patients with psoriasis of blood-heat syndrome were equally assigned, using a randomizing digital table, to the test group treated externally with NPLO and the control group treated with placebo; the medication was done using a singleblinded method twice a day. Meanwhile, all patients received by oral intake a conventional Chinese decoction for clearing heat and cooling blood; the therapeutic course was 4 weeks for both groups. The therapeutic efficacy, changes in the Psoriasis Area and Severity Index (PASI) score and various aspects of the lesion, including scaly eruption, erythema, infiltration, size, score of itching as well as adverse reactions were observed.

RESULTSThe trial was completed in 100 patients, 51 in the test group and 49 in the control group. The remarkably effective rate was 45.10% and the total effective rate was 84.31% in the test group, which were significantly higher than those in the control group, 12.24% and 51.02%, respectively, showing a significant difference between groups (P<0.01). The test group also showed better effects in the improvement of the PASI score of the lesions and scores on erythema, infiltration, size of lesion as well as itching. No adverse event was found in either group.

CONCLUSIONNPLO is a Chinese remedy for the external treatment of psoriasis of the blood-heat syndrome with a reliable therapeutic efficacy and good safety.

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.

Background:Mutations in the isocitrate dehydrogenase 1 (IDH1) and IDH2 genes are important for both the integrated diagnosis and the prognosis of diffuse gliomas.The p.R132H mutation of IDH1 is the most frequently observed IDH mutation,while IDH2 mutations were relatively rarely studied.The aim of the study was to determine the pathological and genetic characteristics of lowergrade gliomas that carry IDH2 mutations.Methods:Data from 238 adult patients with lower-grade gliomas were retrospectively analyzed.The status of IDH1/2 gene mutations,telomerase reverse transcriptase (TERT) promoter mutations,O6-methylguanine-DNA-methyltransferase (MGMT) promoter methylation,1p/19q co-deletion and the expressions of IDH1 R132H,alpha-thalassemia X-linked mental retardation,and p53 were evaluated.Progression-free survival (PFS) and overall survival (OS) were calculated via Kaplan-Meier estimation using the log-rank test.Results:Totally,71％ (169/238) of patients were positive for IDH mutations,including 12 patients harboring mutations in IDH2.Among the 12 patients with IDH2 mutations,ten patients harbored the R172K mutation,one patient harbored the R172S mutation and one harbored the R172W mutation.Of these,11 tumors occurred in the frontal lobe and showed morphology typical of oligodendroglioma.The proportion of grade Ⅱ tumors was higher than that of grade Ⅲ tumors in IDH2 mutant-gliomas.IDH2 mutations were frequently associated with TERT promoter mutations,1p/19q co-deletion and MGMT promoter methylation.IDH2 mutations were associated with better outcomes compared with IDH wild-type gliomas (P ＜ 0.05).However,the PFS and OS did not differ from that of IDH1 mutant patients (P =0.95 and P =0.60,respectively).Conclusions:IDH2 mutations are more frequent in oligodendrogliomas and associated with a better prognosis.IDH2 mutations may segregate in distinct clinico-pathological and genetic subtypes of gliomas,and therefore may merit routine investigation.
