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.

Using sustained release tablets of gardenia extract as model drug and DPPH radical scavenging capacity as antioxidant index, the feasibility of using pharmacodynamics index was explored to evaluate sustained release tablets. Applying the established quantifiable method of DPPH radical scavenging to the dissolved liquid of model drug, release profiles and biological effects profiles were drawn, and their correlation was discussed. A good correlation was observed by linear regression and f2 actor, suggesting that the indicator could be used to evaluate sustained release tabletsofextracts of gardenia in which iridoids were mainly involved.

Based on the structure and function of acupoint and in association of the definition and principle of sensor, the acupoint is the sensitive element, being sensitive to the physical stimulation with acupuncture and moxibustion and sensitively responded to the disorders; the acupoint is the sensing element, transforming the changes of the acupoint information via the complicated internet conduction, integration and regulation, so as to generate the effects on organic body; the acupoint is the conversion element, transforming every irritation into the bioelectric signal or optical signal so that the organic body could recognize it. Therefore, the acupoint is regarded as the sensor of information in the organic body.

Objective To establish an animal model of traumatic optic neuropathy (TON) that resemble to clinical state and study the mechanical principle and change of pathophysiology of its nerve injury for clinical diagnosis and treatment. Methods New Zealand white rabbits were used as the research objects. The method introduced by Wang Yi was repeated and improved. Mild and severe animal models of TON were established by reformed Wang Yi operation separately. After the spring gun struck, all animals were observed on pupils and direct light reflex and received the examinations of pattern reversal visual evoked potentials (PR-VEP). The pathophysiology of normal and injury optic nerve was observed. Results After recovery from anesthesia, the mydriasis and disappearance or dullness of direct light reflex happened in all injured eyes. No brain contusion, infection, orbital fracture and death were found. One optic nerve was broken with complete tanica vaginalis. The latency and amplitude of injured eyes deteriorated gradually. In group B, the waves became flat rapidly. After injury, the optic nerve underwent 3 stages: edema, hyperplasia and atrophy. The pathomorphological changes of injured eyes in group B were more serious than that in group A in any time. Conclusions The reformed operation can establish constant nerve injury with high success rate. In mildly injured eyes, the injury deteriorated gradually. However, part visual function remained. In severely injured eyes, the pathomorphological changes were irreversible sooner after struck, and the visual function lost completely. There is a good correlation between PR-VEP and pathomorphology. PR-VEP can guide the clinical diagnosis and treatment.

OBJECTIVETo evaluate the benefit and safety of continuous femoral nerve block in patients undergoing total knee arthroplasty.

METHODSFrom December 2008 to August 2009, 80 patients with total knee arthroplasty were randomly divided into two groups, 40 patients in each group. In group A the pain-control was dominanted by continuous femoral nerve block, there were 5 males adn 35 females with an average age of (65.0 +/- 4.2) years old; In group B the pump of vein odynolysis was used, there were 5 males and 35 females with an average age of (64.7 +/- 8.5) years old. The treatment of relieve pain continued for 3 days. The pain of visual analog scale (VAS), sleep condition, early-stage rehabilitation and adverse effects were recorded.

RESULTSThe VAS scores of group A was lower than that of group B at 2, 6, 24, 36, 48, 56, 72 h after operation (P < 0.05 or P < 0.01); The sleep condition and early-stage rehabilitation of group A were better than that of group B. The complications of group B occurrenced more than group A; The analgetica of group B were used more than that of group A.

CONCLUSIONThe continuous femoral nerve block is an effective pain relieve method and is benefical to rehabilitation from total knee arthroplasty early.

A full length cDNA fragment encoding for human thrombopoietin receptor c-Mpl has been amplified by RT PCR from the total RNA of human HEL cells. The complete sequence of the cloned cDNA was determined and is identical to that previously reported. Then the fragment was subcloned into the mammalian expression vector pcDNA3 and the resulting plasmid is designated as pcMPL. K562 cells, which do not express c-mpl, were transfected with pcMPL and pcDNA3, respectively. The transformants were selected with G418 and then tested by Northern and Southern blotting. A group of engineered cell lines stably expressing c-mpl have been obtained,which will facilitate further research on the signaling mediated by c-Mpl.
