Abstract: Objective The purpose of this study is to find out the epidemiological and clinical characteristics of male patients with condyloma acuminatum (CA) in Liaocheng area, as well as to improve the understanding of human papillomavirus (HPV) infection and put forward targeted prevention and treatment measures. Methods The clinical data of 159 male CA patients who admitted to Liaocheng People's Hospital from January 2021 to January 2022 were collected, and the epidemiological characteristics, clinical manifestations, infection sites, HPV gene subtypes and other information were analyzed retrospectively. Results Most of the 159 CA patients (range from 15 to 77 years old) were 31-40 years old (31.45%, 50/159), more than half of them had smoking history, and more than 60% had low income (<5 000 yuan/month), multiple sexual partners (≥2) and no condom use habit, 70.44% of the patients had prepuce long combined with prepuce balanitis. 91 cases (57.23%) were single infection, 102 cases (64.15%) were simple low-risk HPV infection. The analysis of risk factors between mixed infection and simple low-risk infection found statistically significant differences in age≤ 40 years old, unmarried, or less affected by education duration of 15 years or less, engaged in the business or service industry, the number of sexual partners or 2, knew not to clean and not to use condoms, while differences in smoking history, alcohol history, monthly income level, and age at first sexual intercourse were not statistically significant. Low-risk HPV6 and/or HPV11 were detected in 139 cases (87.42%). Fifty-seven patients (35.85%) were infected with at least one high-risk HPV. 72.33% of the patients had multiple warts, and the most common sites were around the coronal sulcus and frenulum of the penis Conclusions The incidence of multiple infections and high-risk subtypes is high in male CA patients in Liaocheng area, and most of the patients have low income, low education level and multiple sexual partners. Strengthening the treatment and education follow-up of this population may contribute to the treatment and prognosis of male CA in this area.

RT-PCR amplification of ginseng ?-amyrin synthase gene was successfully performed based on the total RNAs extracted from ginseng hairy roots induced by Agrobacterium rhizogenes A4 using a modified guanidine isothiocyanate-method. Sequence analysis of this gene revealed that its sequence was consistent with the sequence of a previously reported ginseng ?-amyrin synthase gene (GenBank No. AB009030). This gene was inserted into pMD-119T simple vector and transformed into E.coli DH5?. Furthermore antisense plant expression vector of this gene was constructed using the pBI121 vector, laying foundation for studies on antisense regulation of ginseng ?-amyrin synthase gene.

Genetic engineering is a powerful tool in Panax ginseng breeding.Genetic transformation and plant regeneration are the premise and foundation involved in genetic engineering of Panax ginseng.Ginseng can be regenerated through organogenesis or somatic embryogenesis and indirect somatic embryogenesis is mainly used for its regeneration.Summurized the factors influencing plant regeneration such as different explants,different carbohydrates,somatic embryo optimization and hormone-free approach.Ginseng transformation has been achieved by Agrobacterium tumefaciens and Agrobacterium rhizogenes and transgenic ginseng with good characters was obtained by introducing genes associated with biosynthesis of ginsenosides or herbicide gene.Hairy root culture system can supply large scale of ginsenosides,thus effect of rolC genes on ginseng hairy root induction,regeneration and bioreactor culture of hairy root were discussed.Additionally,problems that are present in genetic engineering of Panax ginseng were also discussed in this review.

OBJECTIVETo investigate the root canal curvature of permanent anterior teeth from Chuang population.

METHODS245 anterior teeth from Chuang population were collected and examined by X-ray radiography both from labiolingual and mesiodistal directions. For 218 type I anterior teeth, degree of root canal curvature, radius of curvature and length of the curved part of root canal were measured by a special electronic vernier caliper according to Schneider's and Schäfer's method and the data obtained were analyzed.

RESULTSRoot canals of anterior teeth from Chuang population were mainly of type I. The number of type II, III, IV were about 13 in mandibular central and 12 in mandibular lateral incisors. The incidence of curvature in maxillary central incisors, lateral incisors, canines and mandibular central incisors, lateral incisors, canines were 40%, 80%, 77%, 65%, 66%, 73% in mesiodistal directions, 62%, 69%, 70%, 62%, 41%, 61% in labiolingual directions respectively. The most curvature was moderate and happened in apical third. The heaviest curvature occurred in maxillary canines in mesiodistal direction and mandibular canines in labiolingual direction. The shortest radius and length of curvature occurred in maxillary lateral incisors.

CONCLUSIONRoot canal curvature of anterior tooth in Guangxi Chuang population is complex. The incidence of type II, III, IV is high in mandibular incisors.

AIMTo study the antidiabetic effects of cortex Moutan polysaccharide-2b (CMP-2b) in type 2 diabetes mellitus (T2DM) rats.

METHODSThe T2DM model rats were induced by a single intravenous injection of low dose streptozotocin (STZ) and intake of high sucrose-fat diet. CMP-2b was given to T2DM rats daily through gavage for 4-5 weeks. The body weight, water and food intake, fasting blood glucose (FBG), glucose tolerance, plasma lipids, serum insulin, and insulin receptor (Ins R) were determined.

RESULTSOral administration of CMP-2b significantly decreased water and food intake, FBG, total cholesterol (Tch), and triglyceride (TG), improved the impaired glucose tolerance (IGT), and remarkably raised the number of low affinity InsR and insulin sensitivity index (ISI) in T2DM rats.

CONCLUSIONCMP-2b may be useful for treating T2DM and its complications.

OBJECTIVETo evaluate the effect of root canal taper and post on tooth stress distribution.

METHODSThree-dimensional finite element models of human mandibular first molar with root canals prepared with 35# K file, ProTaper and Profile were established. The tooth were restored with fiber-resin, stainless steel and silver amalgam posts respectively. A vertical load on tooth occlusal surface was simulated. Marc software was used to analyze and calculate the stress distributions in the tooth restored with three kinds of different root canal posts, especially the in the cervical part and root.

RESULTSDifferent tapered root canals had no obvious influence on stress distribution in all three different posts. Stress distribution of stainless steel post located at the cervical and middle part of distal root, the highest Von-Mises stress was about 45 MPa. Stress distribution of silver amalgam post located at the orifice of root canal and pulp fundus, the highest Von-Mises stress was about 16 MPa. Stress distribution of fiber-resin post had no obvious stress concentration.

CONCLUSIONSFiber-resin post is the most ideal root canal post. Stainless steel post causes remarkable stress concentration in the root, which may raise the possibility of root fracture.

OBJECTIVETo determine the effect of composite restoration on reinforcement of weakened tooth structure and the possible mechanism.

METHODSSixty freshly extracted non-carious maxillary premolars were collected and divided into 6 groups with 10 specimen in each group. MOD cavities (buccolingual width: 2.8 to 3.2 mm; palatal cusp width: 2.0 mm; cusp height: 5.0 mm) were prepared individually. Group 1 was prepared and not restored (control). The other 5 groups were restored with silver amalgam alloy (group 2), Z250 without bonding (group 3), F2000 (group 4), Z250 (group 5) and Z350 nanocomposite (group 6) (3M ESPE) respectively. The fracture resistance of the tested teeth was determined by applying a vertical splitting load through a specially shaped steel rod at a crosshead speed of 1 mm/min. The data were analyzed by ANOVA.

RESULTSThe average fracture resistance of the 6 groups was: (245.29 +/- 39.49) N (group 1), (255.09 +/- 42.14) N (group 2), (267.34 +/- 31.56) N (group 3), (293.90 +/- 33.42) N (group 4), (337.81 +/- 32.63) N (group 5) and (349.08 +/- 32.93) N (group 6). There was no significant difference between the group 1, group 2 and group 3. The fracture resistance of group 4, group 5 and group 6 was higher than that of group 1 and group 2 (P < 0.05). Significant difference was noted between group 5 and group 3 (P < 0.01). The fracture resistance of group 4 was much lower than that of group 5 and group 6 (P < 0.01). No significant difference was found between group 5 and group 6.

CONCLUSIONSThe use of composite increased the fracture resistance of the tooth with an MOD restoration. This effect was related to the adhesive force, polymerization shrinkage stress and the elastic modulus of the composite.
