Geographic tongue, also called benign migratory glossitis, is a common and superficial benign inflammatory disorder that affects the tongue epithelium. The majority of geographic tongue lesions typically manifest as irregular central erythematous patches. These lesions, which are caused by the loss of filiform papillae, are defined by an elevated whitish band-like border that can change location, size, and pattern over a period of time. Histological observations of the oral mucosa affected by geographic tongue revealed nonspecific inflammation. Some reports described cases of migratory stomatitis, wherein lesions simultaneously manifested on the extra lingual oral mucosa. This condition is also called ectopic geographic tongue, which is clinically and histologically similar to the type normally confined to the tongue. In most cases, patients are asymptomatic and do not require treatment. The condition may spontaneously exhibit periods of remission and exacerbation with good prognosis. The specific etiology of geographic tongue remains unknown. Geographic tongue is age-related and is prevalent among young individuals. Various etiological factors that have been suggested in literature include immunological factors, genetic factors, atopic or allergic tendency, emotional stress, tobacco consumption, hormonal disturbances, and zinc deficiency. Geographic tongue may coexist with other disorders, such as fissured tongue, psoriasis, diabetes mellitus, gastroin- testinal diseases, burning mouth syndrome, and Down syndrome. Experts currently disagree on whether geographic tongue is an oral manifestation of psoriasis. Moreover, some scholars suggest that geographic tongue is a prestage of fissured tongue. The objective of this review is to summarize current research on risk factors of geographic tongue.

ObjectiveTo investigate the epidemic situation of brucellosis in Datong city, and to provide scientific evidence for making appropriate prevention and control measures. MethodsSurveillance data of human brucellosis in 7 countris and 4 districts in Datong city between 2006 and 2009 were collected, throng the national network straight quote system in an infectious diseases. Excel database was established and all data were statistically analyzed. Incidence of brucellosis in local population was analyzed. The regional distribution, time distribution,occupation, age and sex distribution were analyzed. Epidemic characteristics and trend of brucellosis in Datong city were summarized. Results A total of 5195 cases of brucellosis patients in Datong were found between 2006 and 2009, the average incidence rate was 57.51/10 million. All counties had the disease, and the onset of the disease mainly in the spring and summer. Most cases were young males. Farmer case was 81.67％(4243/5195) of the total patients. ConclusionsFrom 2006 to 2009, epidemic characteristic of Datong human brucellosis ishigh-low-high(incidence). We suggests the Department concerned to strengthen the prevention and control of the disease in some counties, focusing on spreading of disease prevention and control knowledge among farmers and increase their self-protection awareness.

Effects of 7 fungus strains on tobacco quality by applying fungal leavens on upper leaves were studied. Results showed that BF03, BF06 and BF63 can remarkably change the chemical components of tobacco, such as soluble sugar, protein, nicotine etc., and make them more harmonious. And the smoking quality of the flue-cured tobacco leaves treated was much better than the control.

Purpose: We investigated the effect of preoperative administration of analgesics and sedatives on pain levels during silicone tube intubation conducted under local anesthesia in patients with acquired nasolacrimal duct stenosis. Methods: We retrospectively reviewed the medical records from 121 patients at the ophthalmology department of our hospital from July 2016 to May 2022. In total, 71 patients were administered acetaminophen and diazepam orally, while the remaining 50 were not. Postoperative pain (measured using the visual analogue scale [VAS] score [0 = no pain, 10 = severe pain] immediately after operation), operative duration, and improvement in epiphora symptoms were compared between the two groups. Results: The premedication group had significantly lower VAS scores than the non-premedication group (5.23 ± 2.75 vs. 6.34 ± 2.33, p = 0.02). It also had a notably shorter (p < 0.01) operation duration and higher subjective improvement rate of epiphora symptoms. However, premedication did not influence the tube retention period post-surgery (p = 0.86). Conclusions The administration of analgesics and sedatives prior to silicone tube intubation effectively mitigates operative pain and reduces operation duration. Furthermore, it may help improve postoperative epiphora symptoms.

Objective To explore the biomechanical function of PCL and its different bundles and examine the biomechanical impact of posterior cruciate ligament (PCL) integrity on the medial femoral condyle. Methods Twelve fresh human cadaveric knee specimens were subjected to different axial load (0-800 N) at 0°, 30°,60°, and 90°of knee flexion. Four surgical treatments were carried out for biomechanical testing: PCL intact, anterolateral bundle (ALB) rupture, posteromedial bundle (PMB) rupture and PCL rupure. During the test, strains of middle part of the medial femoral condyle were calculated. Results At O°knee flexion, increasing strain of the medial femoral condyle was detected in PMB rupture and PCL rupture under all loading conditions. No significant difference of strain of the medial femoral condyle was noted between PCL intact and ALB rupture under any loading conditions. Compared to PMB rupture, PCL rupture had not higher strain of the medial femoral condyle under all loading conditions. At 30°, 60° and 90° knee flexion, increasing strain of the medial femoral condyle was noted in ALB rupture under higher loading conditions and PCL rupture under all loading conditions. ALB rupture under lower loading conditions and PMB rupture under all loading conditions did not significantly increased strain of the medial femoral condyle. PCL rupture had higher strain of the medial femoral condyle than ALB rupture under most of loading conditions.Conclusion The data suggest that PMB is the major stabilizing bundle of PCL in full extension, ALB is the major stabilizing bundle of PCL in knee flexion, and both bundles function through the ROM in a codominant fashion. Partial and complete ruptures of PCL may have hazardous biomechanical impacts on the medial femoral condyle during normal movement.

Objective To investigate the personality of head nurse,and provide date for correct evaluating,training and selecting of head nurse scientifically,improving the level of nurse management and the quality of clinical care.Methods 47 head nurses were assessed in the study by Eysenck Personality Questionnaire(EPQ).Results The EPQ results showed that the extroversion introversion score is significantl higher than that of norm's(P<0.01).The neuroticism(N)score is significantly lower than that of the norm' s.Both P score and L score are similar with that of the norm's.Qualifications of the head nurses in different personality traits were not different.But the n scores of different ages are different.Conclusions Most nurses are extrovert personality.Neuroticism in most head nurse was better than that of the norm,but 40-year-old nurse in the following aspects of neuroticism scores was more than younger nurse.That indicated that low-life nurse is not mature enough,and emotional control is not as good as that of high-life nurse.The guidance was required to be further strengthened.

OBJECTIVES: Fast-setting pozzolan cement (Endocem, Maruchi) was recently developed. The aim of this study was to investigate the effects of various root canal irrigants on the washout of Endocem in comparison to the previously marketed mineral trioxide aggregate (ProRoot; Dentsply) in a furcal perforation model. MATERIALS AND METHODS: ProRoot and Endocem were placed into acrylic molds on moist Oasis. Each mold was then immediately exposed to either physiologic saline, 2.5% sodium hypochlorite (NaOCl), or 2% chlorhexidine (CHX) under gentle shaking for five minutes. Washout testing was performed by scoring scanning electron microscope (SEM) images. RESULTS: Endocem exhibited higher washout resistance compared to ProRoot, especially in the NaOCl group. CONCLUSIONS: These results suggest that Endocem can be considered a useful repair material for furcal perforation, especially in a single-visit scenario.

Cavernous hemangiomas rarely involve the female genital tract. It is difficult to identify vascular malformations when these lesions are concealed in the vagina or deep vulva area. We present a rare case of vaginal cavernous hemangioma in a 30-year-old primiparous woman with an early severe postpartum hemorrhage (PPH) and delayed continuous bleeding from the episiotomy site. She was treated successfully with transarterial embolization of the left vaginal artery. To our knowledge, this is the first reported case of PPH caused by rupture of a vaginal hemangioma during vaginal delivery in English literature.
