Medical history summary: Male, 47 years old, was admitted to the hospital due to “dizziness accompanied by chest tightness and pain for more than 8 days”. One week ago, the patient experienced chest tightness, chest pain accompanied by profuse sweating for 3 hours and underwent emergency percutaneous coronary intervention (PCI) at a local hospital. The procedure revealed left main stem occlusion with subsequent left main stem to left anterior descending artery percutaneous transluminal coronary angioplasty (PTCA). After the procedure, the patient experienced hemodynamic instability, recurrent ventricular fibrillation, and critical condition, thus transferred to our hospital for further treatment. Symptoms and signs: The patient is in a comatose state, unresponsive to stimuli, with bilateral dilated pupils measuring 2.0 mm, exhibiting reduced sensitivity to light reflex, and recurrent fever. Coarse breath sounds can be heard in both lungs, with audible moist rales. Irregular breathing pattern is observed, and heart sounds vary in intensity. No pathological murmurs are auscultated in any valve auscultation area. Diagnostic methods: Coronary angiography results at the local hospital showed complete occlusion of the left main stem, and left main stem to left anterior descending artery percutaneous transluminal coronary angioplasty (PTCA) was performed. However, the distal guidewire did not pass through. After admission, blood tests showed a Troponin T level of 1.44 ng/ml and a Myoglobin level of 312 ng/ml. The platelet count was 1390 × 10<sup>9</sup>/L. Von Willebrand factor (vWF) activity was measured at 201.9%. Bone marrow aspiration biopsy showed active bone marrow proliferation and platelet clustering. The peripheral blood smear also showed platelet clustering. JAK-2 gene testing was positive, confirming the diagnosis of primary thrombocytosis. Treatment methods: The patient is assisted with mechanical ventilation and intra-aortic balloon counterpulsation to improve coronary blood flow. Electrolyte levels are closely monitored, especially maintaining plasma potassium levels between 4.0 and 4.5 mmol/l. Hydroxyurea 500 mg is administered for platelet reduction. Anticoagulants and antiplatelet agents are used rationally to prevent further infarction or bleeding. Antiarrhythmic, lipid-lowering, gastroprotective, hepatoprotective, and heart failure treatment are also provided. Clinical outcome: The family members chose to withdraw treatment and signed for discharge due to a combination of reasons, including economic constraints and uncertainty about the prognosis due to the long disease course. Acute myocardial infarction has gradually become one of the leading causes of death in our country. As a “green channel” disease, corresponding diagnostic and treatment protocols have been established in China, and significant progress has been made in emergency care. There are strict regulations for the time taken from the catheterization lab to the cardiac intensive care unit, and standardized treatments are provided to patients once they enter the intensive care unit. Research results show that the incidence of acute myocardial infarction in patients with primary thrombocythemia within 10 years is 9.4%. This type of disease is rare and difficult to cure, posing significant challenges to medical and nursing professionals. In order to benefit future patients, we have documented individual cases of treatment and nursing care for these patients. The research results show that these patients exhibit resistance to traditional oral anticoagulant drugs and require alternative anticoagulants. Additionally, there are significant differences in serum and plasma potassium levels among patients. Therefore, when making clinical diagnoses, it is necessary to carefully distinguish between the two. Particularly, nursing personnel should possess dialectical thinking when supplementing potassium levels in patients in order to reduce the incidence of malignant arrhythmias and mortality rates. 展开更多

As a result of this, the penis appears shortened in length. It was first described by Keyes Jr. E.L. in 1919. It can be associated with voiding problem and in adults, sexual issues, among others. Objective: To show that surgery can reverse celibacy induced by CP and highlight the need for an interdisciplinary approach to correction of this anomaly. Patient and Method: A thirty-one-year male patient who had a surgical release of his buried penis by two surgeons in 2019 in a private hospital. The case note was reviewed, the data obtained analyzed and the results including photographs, were presented. The patient was followed up. Result: A 10 cm length of penis and a hundred percent (100%) take of sheet of split skin graft used to resurface the denuded penis were achieved using combined spinal and epidural anesthesia. The patient, his mother and the surgeons were satisfied with the outcome. Consequently, he resolved to marry a wife after all. Conclusion: Concealed penis can now be regarded as a known cause of celibacy and surgical correction can reverse the celibate state. 展开更多

Recently, a number of large molybdenum (-copper) deposits have been discovered successively in the Laba area, Shangri-La county, northwestern Yunnan province. The investigation confirmed that there is a superlarge porphyry-skarn hydrothermal vein type molybdenum-polymetallic- metallogenic system with the total prediction reservoir of more than 150 mt molybdenum. The porphyry intrusions contributed to the mineralization closely, the superficial little vein molybdenum (-copper, lead, silver) ore-bodies are usually located in faults and fractures, and the deep porphyry type ore-bodies occurred in the granodiorite porphyries, the skarn type ore-bodies occurred in the contact zone intrused into Triassic limestone or Permian basalts. Laba ore block is a new exploration area with great prospecting potential. In order to reduce the target area and guide the further exploration work, the magnetic method measurement about 3.3 square kilometres was carried out in the ore field. This paper presents an application of analyzing the horizontal and vertical derivative, using Fast Fourier Transform (FFT) filter (FFT high-pass, low-pass, cosine roll-off, suscepbility), calculated spectra frequency energy to predict the depth and intensity of the apparent remanence magnetization of source (Hilbert). The calculated results and magnetic anomalous show that the remanence anomaly is caused by the intrusions into the Triassic limestone and Permian basalts with small anomalies, and the depth of located source is not great. We have identified a number of positions to the three drilled well, the drilled result specify interpretation with very high accuracy. The magnetic method is helpful to identify porphyry mineralization, and judge the shape and depth of the concealed ore-bearing intrusive bodies under the similar geological condition. 展开更多

The results of recent mineral exploration in the Yuele lead-zinc mining area of Daguan County, northeastern Yunnan province, showed that there are much early Paleozoic strata under thick late Paleozoic strata in northeastern Yunnan province, where developed some hidden salt structures (SSs), often with lead-zinc polymetallic mineralization varying degrees along the tension torsional fault (belts) or fracture (joint). The ore-bodies belong to the epigenetic hydrothermal filling vein-type deposit, and the prospecting potential is great. In this area, the superficial mineralization information displayed clear, but the deep mineralization is unknown, so the exploration work is restricted. The audio-megnetotelluric (AMT) surveying is an advantageous method to characterize the size, resistivity and skin depth of the polarizable mineral deposit concealed beneath thick overburden. This paper presents the surveying results using AMT method to evaluate the concealed lead-zinc mineralization in Yuele lead-zinc ore field, Daguancounty, NE Yunnan province, China. After comparing the interpretation result of AMT surveying data with the geological data and the drilling data, it is found that there is some distinct difference in resistivity and polarizable between ore-bodies hosted strata, upper strata and gypsum strata. The results show that AMT method is helpful to identify lead-zinc mineralization under this geological condition. 展开更多

In order to further improve the seismic performance of RC shear walls, a new composite shear wall with concrete filled steel tube (CFT) columns and concealed steel trusses is proposed. This new shear wall is a double composite shear wall; the first composite being the use of three different force systems, CFT, steel truss and shear wall, and the second the use of two different materials, steel and concrete. Three 1/5 scaled experimental specimens: a traditional RC shear wall, a shear wall with CFT columns, and a shear wall with CFT columns and concealed steel trusses, were tested under cyclic loading and the seismic performance indices of the shear walls were comparatively analyzed. Based on the data from these experiments, a thorough elastic-plastic finite element analysis and parametric analysis of the new shear walls were carried out using ABAQUS software. The finite element results of deformation, stress distribution, and the evolution of cracks in each phase were compared with the experimental results and showed good agreement. A mechanical model was also established for calculating the load-carrying capacity of the new composite shear walls. The results show that this new type of shear wall has improved seismic performance over the other two types of shear wails tested. 展开更多

The detection technology of concealed bulk explosives is related to social security and national defense construction and has important research significance. In this paper, an element analysis method of concealed explosives based on thermal neutron analysis is proposed.This method could provide better reconstruction precision for hydrogen, carbon, and nitrogen ratios, making it possible to discriminate explosives from other compounds with the same elements but different proportions, as well as to identify the types of concealed bulk explosives. In this paper, the basic principles and mathematical model of this method are first introduced, and the calculation formula of the element number ratio(the ratio between the nucleus numbers of two different elements) of the concealed explosive is deduced. Second, a numerical simulation platform of this method was established based on the Monte Carlo JMCT code. By calibrating the absorption efficiencies of the explosive device to c rays, the element number ratios of a concealed explosive model under the irradiation of thermal neutrons were reconstructed from the neutron capture prompt c-ray spectrum. The reconstruction values were in good agreement with the actual values,which shows that this method has a high reconstruction precision of the element number ratio for concealed explosives. Lastly, it was demonstrated using the simulation study that this method can discriminate explosives,drugs, and common materials, with the capability of determining the existence of concealed bulk explosives and identifying explosive types. 展开更多

Palynological and paleontological investigations supported by the radiocarbon dates of the lacustrine sediments of two profiles from the temperate lake Saria Tal, in Naini Tal District, Kumaun Himalaya, have revealed the presence of a concealed fold at the region. The profile from bore cores represents the upper part of the Late Holocene and the profile from exposed sections from the Middle Holocene to the over middle part of the Late Holocene. The data generated from different investigations have uniformly indicated that the former profile represents normal superposition, while the latter represents the reverse order. The contemporary pollen as well as molluscan zones of both profiles are situated at different elevations but consist of similar bioremains - indicating continuation of the same strata in two profiles. The presence of reverse order of superposition, continuation of the same strata in two profiles at different elevations, and the orientation of biozones, have indicated that the revealed folding is of syncline type. The present study has also given an idea about the origin of this lake. 展开更多

Identifying ore-induced geochemical anomalies at the surface that indicate concealed deposits in buried areas remains a significant challenge in geochemical exploration. In this study, in order to trace the source of the geochemical anomalies, systematic luminescence intensity analyses were conducted on quartz grains from the Quaternary regolith at the Hadatu sandstone-type uranium deposit in the Erenhot Basin. The optically stimulated luminescence(OSL) ages were much older than the depositional ages of the Quaternary regolith. Moreover, quartz OSL ages were closely related to both borehole grades and sampling depths. Thus, the abnormal mineral OSL ages from near-surface sediments were ultimately controlled by the sandstone-type uranium deposits. This is identical to the rapid changes of quartz OSL ages(0.063 ka/cm) and equivalent doses(0.19 Gy/cm) with depths in a given sampling site. The instantaneous soil radon concentration was positively correlated with the quartz OSL apparent age, indicating their ore-induced origin and, as a result, their effectiveness in the exploration of concealed uranium deposits. Other parameters, including mobile-state uranium and;Po contents, were poorly correlated with quartz OSL ages and therefore should only be used with caution for geochemical exploration. This is the first time an attempt has been made to discriminate the ore-induced sources for different surface anomaly parameters, including instantaneous soil radon, mobile-state uranium and;Po contents for concealed sandstonetype uranium deposits. 展开更多

To address the issues for assessing and prospecting the replaceable resource of crisis mines,a geological ore-controlling field model and a mineralization distribution field model were proposed from the viewpoint of field analysis. By dint of solving the field models through transferring the continuous models into the discrete ones,the relationship between the geological ore-controlling effect field and the mineralization distribution field was analyzed,and the quantitative and located parameters were extracted for describing the geological factors controlling mineralization enrichment. The method was applied to the 3-dimensional localization and quantitative prediction for concealed ore bodies in the depths and margins of the Dachang mine in Guangxi,China,and the 3-dimensional distribution models of mineralization indexes and ore-controlling factors such as magmatic rocks,strata,faults,lithology and folds were built. With the methods of statistical analysis and the non-linear programming,the quantitative index set of the geological ore-controlling factors was obtained. In addition,the stereoscopic located and quantitative prediction models were set up by exploring the relationship between the mineralization indexes and the geological ore-controlling factors. So far,some concealed ore bodies with the resource volume of a medium-sized mineral deposit are found in the deep parts of the Dachang Mine by means of the deep prospecting drills following the prediction results,from which the effectiveness of the predication models and results is proved. 展开更多

Based on the research content and conception of dynamics of tectonic ore-forming processes, with the focus on the dynamics and processes of mineral source, ore formation, transport, accumulation, dissipation and mineralization in response to magmatic invasion and metallogenic fluid under tectonic stress, this paper deals with the ore-finding method of fault tectono-geochemistry and its application on the basis of ore deposit genesis, "giant pressure shadow" structure and ore-finding method of tectonic stress field in the Tongchang orefield, expounds the rules of magmatic emplacement and ore fluid migration and concentration under the control of the structural stress field, hence providing the theoretical basis for the localization and prognosis of concealed ores. The fault tectono-geochemical features show that the Cu-Au polymetallic ore deposits (mineralization) in the orefield are closely related with volcano-(exhalation) sedimentation, magmatism and tectono-reworking. Fault tectono-geochemical anomalies can be applied to prognosis of metallogenetic target areas for ore exploration and can provide strong evidence of "giant pressure shadow" structure. In addition, quite a number of important target areas have been defined in combination with the characteristics of the tectonic stress field, and part of the target areas have been proved by practical activities. 展开更多

Purpose: Phimosis can be treated using topical steroid treatment effectively. Meanwhile, concealed penis has been required surgical correction because it was considered stubborn to conservative treatment. But there were few reports of conservative treatment using topical steroid treatment for concealed penis. The aim of the present study was to evaluate the effects of topical steroid treatment for concealed penis. Materials and Methods: From December 2006 to December 2011, 30 patients (mean age 9.3 years) with concealed penis were treated with topical 0.12% bethamethasone valerate cream. Patients or their parents continued to retract the prepuce gently without causing pain and to apply a topical 0.12% bethamethasone valerate cream to the prepuce twice daily for 6 weeks. When topical steroid treatment was ineffective, patients were surgically corrected. Results: The success rate of topical steroid treatment was low (10%). 27 of 30 patients required surgical repair. No patients showed complications associated with topical steroid or surgical intervention. Conclusions: Concealed penis is highly resistant to topical steroid treatment and should be corrected surgically. 展开更多
