Pegmatite Fluids of Different Origins and Their Implications for Mineralization

Characteristics of ore forming fluids as inferred from detailed studies of inclusions indicate that pegmatites may have different origins. For example, the granitic pegmatite at Mufushan is originated from magma differentiation at 1100-200℃, while the No.3 Pegmatite Vein in Xinjiang may owe its origin to a pegmatitic magma produced via metamorphic anatexis at 1140-200℃. Pegmatite fluids of the above two types are a melt liquid system and may evolve into a solid melt or solid liquid system that would have a critical bearing on metasomatism and intergranular solutions. The Minxi pegmatite, on the other hand, resulted from metamorphic differentiation, with its fluid (formed at 400-180℃) exhibiting many features of metamorphism. Pegmatites of different origins are distributed in tectonic units of different characters and are different both in the nature of ore forming fluid and in the source of ore metals. This concept of polygene launches a challenge to the traditional belief that pegmatite is exclusively originated from magma differentiation and may be helpful for the establishment of a new theory of pegmatite genesis.

Effect of intervention treatment from different stages on prognosis in children with central coordination disturbance

BACKGROUND： Central coordination disturbance is regarded as the early-stage symptom of brain injury-induced cerebral palsy. This disease manifests itself as motor disorder, abnormal attitudinal reflex and muscular tension. Early intervention may improve its prognosis. OBJECTIVE： To observe the effects of intervention treatment from different stages on the prognosis of central coordination disturbance following brain injury in children patients. DESIGN： A contrast observation experiment SETTING： Department of Neurology and Rehabilitation, Urumqi Children＇s Hospital PARTICIPANTS ： Totally 151 children who were diagnosed as central coordination disturbance from January 2002 to December 2003 in the Department of Neurology and Rehabilitation of Urumqi Children＇s Hospital were recruited. All the children patients, including 101 male and 50 female, aged from 3 months to 1 year old, met the diagnosis criteria of central coordination disturbance from Vojta. They were divided into slight, moderate and severe abnormity according to Vojta attitudinal reflex. All 151 patients were divided into 2 groups according to their age at diagnosis： 3-6 months old group （n=74）, 62 severe, 10 moderate and 2 slight; 7-12 months old group （n=77）, 66 severe, 7 moderate and 4 slight. All the relatives of children patients were informed of the experiment. METHODS： ① Both groups received physical training （PT） as the main treatment; Hand training was given if necessary. All of the patients received additional hyperbaric oxygen therapy, bioelectric therapy, scalp acupuncture, drug treatment and family training. The importance of integration of hospital and family based rehabilitation was stressed. Those who did not catch up with the normal development or had abnormal reflexes continued to receive treatment. ② Around the age of 2 years old, all children did a final evaluation using Bayley Scales of Infant Development （BSID）. Mental development index （MDI） and physical development index （PDI） were taken as evaluative criteria. Children with scores 80 and above on MDI and PDI were considered to have normal motor and mental development; 79 and below were considered delayers. The Diagnostic Criteria of Cerebral Palsy and Infantecondary School Social Adaptation Scale were used in the final evaluation[scores ≤5 was extremely severe （extremely severe cerebral palsy）, 6 was severe（severe cerebral palsy）, 7 was moderate（moderate cerebral palsy）, 8 was slight（slight cerebral palsy）, 9 was borderline（slight cerebral palsy）, 10 was normal, 11 was above average, 12 was excellent and ≥13 was extremely excellent]. ③ Final evaluative results of 2 groups were compared. And u test was used for the comparison of Bayley development index and Chi-square test for the comparison of normalization rate. MAIN OUTCOME MEASURES： BSID MDI and PDI as well as the normalization rate of motor function and mental behavior of children patients at 2 years old. RESULTS： Totally 151 children patients entered the stage of result analysis. ①Two groups of children patients were given integrated rehabilitation therapy , and evaluated at 2 years old . The 3-6 months old group had higher MDI and PDI than the 7-12 months old group （91.81＋19.99 vs 71.93＋18.98;91.55＋23.61 vs 68.95＋23.51, u=6.265,5.894,P 〈 0.01 ）.②After being given integrated rehabilitation therapy, children patients of 3-6 months old group had significantly higher normalization rate of motor function and mental behavior than 7-12 months old group （73% ,27%,X2=29.723 9,P 〈 0.01 ）. ③Six slight and 17 moderate central coordination disturbance children of 2 groups all completely recovered; After intervention treatment, among 128 severe central coordination disturbance children, 52 recovered and 76 were still abnormal, in which, 43 slight cerebral palsy, 18 moderate cerebral palsy, 5 severe cerebral palsy and 10 extremely severe cerebral palsy. CONCLUSION： To perform integrated intervention treatment before 6 months old can better improve and promote mental and physical development levels of children patients with central coordination disturbance after brain injury than 6 months later.

Effects of Different Treatments on Seed Germination of Gagea nigra

According to different mechanisms of dormancy,seeds of Gagea nigra L.Z.Shue were treated with different methods so as to investigate the effects of different treatments on seed germination of G.nigra.The results showed that at 4 ℃,the seeds of G.nigra began to germinate on day 32 with germination period of 80 d and germination rate of 72%;room temperature（25 ℃） and acid and alkali treatments were all unsuitable for the germination of G.nigra seeds;no significant differences were found in germination rate of G.nigra seeds among warm water（50℃）,ultrasound and 200 mg/L GA_3treatments（P 0.05）;seed coat-removing treatment effectively promoted the germination of G.nigra seeds（P =0.002 0.01） with germination rate of 88%;seed coat piercing ＋ 200 mg/L GA_3 and 500 mg/L GA_3＋15% H_2O_2 treatments effectively promoted the germination of G.nigra seeds with germination rates of 84% and 82%,respectively（P0.05）;the germination vigor of G.nigra seeds in the seed coat piercing ＋ 200 mg/L GA_3 treatment was highest,and it was significantly higher than those in the other treatments.

Effects of Different Fertilization Treatments on Biological Activity of Reclaimed Soil

As per randomized block design, the research had different fertilizer treatments, and the organic matter, respiration, enzyme activity and microbial carbon and nitrogen in reclaimed soil were studied. Fertilization schemes were as follows： The treatment without fertilizers（CK）, the treatment with chemical fertilizers（C）, the treatment with chemical fertilizers and bacterial fertilizer（CB）, the treatment with organic fertilizer and chemical fertilizers（CM）, and the treatment with chemical fertilizers, organic fertilizer and bacterial fertilizer（CMB）. The results showed： Four fertilization treatments could improve the content of soil organic matter. CMB, CM and CB could significantly improve the soil respiration. Organic fertilizer and fertilizer could significantly improve soil enzyme activity, In different growth stages the CMB treatment had highest urease and phosphatase.The most significant in the treatment content of sucrose was CM. Organic fertilizer and microbial fertilizer can significantly improve the microbial carbon and nitrogen in soil. For the microbial biomass carbon, the CMB treatment increased by 11%-34% than CB treatment, and 35%-63% than C treatment. In terms of microbial nitrogen CMB, CM respectively increased by 31%-51% than CB treatment, and 52%-100% compared with C. In the process of land reclamation, we should combine the organic fertilizer, microbial fertilizer and inorganic fertilizer. Only in this way can soil biological activity be accelerated, soil microbial environment improved, and the ripening increased soil nutrient and soil cultivation be enhanced.

Cone beam computed tomography-guided differences among registration methods for lung cancer and the effects of tumor position,treatment model,and tumor size on positioning errors

Objective To explore the differences in three different registration methods of cone beam computed tomography(CBCT)-guided down-regulated intense radiation therapy for lung cancer as well as the effects of tumor location,treatment mode,and tumor size on registration.Methods This retrospective analysis included 80 lung cancer patients undergoing radiotherapy in our hospital from November 2017 to October 2019 and compared automatic bone registration,automatic grayscale(t+r)registration,and automatic grayscale(t)positioning error on the X-,Y-,and Z-axes under three types of registration methods.The patients were also grouped according to tumor position,treatment mode,and tumor size to compare positioning errors.Results On the X-,Y-,and Z-axes,automatic grayscale(t+r)and automatic grayscale(t)registration showed a better trend.Analysis of the different treatment modes showed differences in the three registration methods;however,these were not statistically significant.Analysis according to tumor sizes showed significant differences between the three registration methods(P<0.05).Analysis according to tumor positions showed differences in the X-and Y-axes that were not significant(P>0.05),while the autopsy registration in the Z-axis showed the largest difference in the mediastinal and hilar lymph nodes(P<0.05).Conclusion The treatment mode was not the main factor affecting registration error in lung cancer.Three registration methods are available for tumors in the upper and lower lungs measuring<3 cm;among these,automatic gray registration is recommended,while any gray registration method is recommended for tumors located in the mediastinal hilar site measuring<3 cm and in the upper and lower lungs≥3 cm.

SARS-CoV-2 Infected Cases with Untraceable Epidemic Origin:Its Values,Identification and TCM Treatment in Preventing Recurrence

During the outbreak of coronavirus disease 2019(COVID-19),the identification of a SARS-CoV-2 infected case with untraceable epidemic origin has three values:(1)the region has community transmission of the virus;(2)a certain portion of population in the community is getting immunized and more individuals have already been immunized;(3)an unpredictable future risk exists for regions where there are no infected cases with untraceable epidemic origin.Minimizing or avoiding the aggregation infection through individuals with no clinical symptoms is crucial and possible as its occurrence is mainly attributed to the local environment as opposed to the super spreader with or without clinical symptoms.As infected cases are not necessarily positive with gene test by definition,proper application of gene test is crucial in the identification of asymptomatic cases.In the early stage of an outbreak of infectious disease,gene test can be used to identify asymptomatic cases but it should not be used to exclude cases with typical clinical symptoms and signs.In the middle or late stages of an outbreak gene test should be applied in evaluation of infection rate of the population of a region,in addition to be used in spreader identification and isolation.Although asymptomatic cases are attributed to the overwhelming effect of personalized defense against pathogens,they are still a source of infection.Asymptomatic cases are considered to be Qi deficiency and with lingering toxicity in traditional Chinese medicine(TCM).Treatment in such cases,typically,involves therapy focused on replenishing the Qi,tonifying the lung,clearing the fever,and detoxification in order to return to a normal health condition.The recommended Chinese medicines include Qing Fei Pai Du Decoction,Yi Qi Qu Du Decoction,Xuan Fei Bai Du Granule,Lian Hua Qing Wen Capsule(Granule),and Jin Hua Qing Gan Granule,etc.

Effect of Different Treatment Rapeseeds on Activity of Cellulose Enzyme in Sheep

The purpose of the experiment is to research the effect of different rapeseed treatments feeding on activity of cellulose enzyme in sheep. Eight male adults of semi-fine wool sheep breeds with the same weight and permanent rurnen cannulas were selected according to 4×4 Latin square design to determine the effect of different rapeseed treatment groups including crushed rapeseed, whole rapeseed, extruded rapeseed （dietary lipid content of =67 g·kg^-1） and control group （dietary lipid content of =30 g·kg^-1） on activity dynamic variation of ruminal celluolytic enzyme in sheep. The results showed that ruminal fluid pH matched up to the condition of fiber degradation and growth of cellulolytic bacterium when fed four diets; but there was significant difference （P〈0.05） for the activity of microcrystalline cellulose, glucanase, salicin enzyme involved in ruminal fiber degradation after fed 2, 4, 6 h.

COVID-19 Infection: The Virus and Its Origin, the Variants, the Immune Defense, the Multiorgan Autoimmune Reactions, and the Targeted Treatments

Background: SARS-CoV-2, the virus responsible for the current COVID-19 infection pandemic, has caused substantial damage and negative impacts in the world, including physical sickness, mental illness, death, society lock down, work interruption, and productivity reduction. From the onset in early 2020, the pandemic has not yet totally subsided as of July 2022. Although great efforts have been made to understand the nature of this pandemic by the medical and scientific communities, a comprehensive review of this pandemic has not been reported. Purpose: We aimed to perform a thorough review of the subject in order to come to a better understanding of the origin of the virus, its mutations and their corresponding health effects, its pathophysiology, and its responses to therapeutic intervention. A more comprehensive set of data on these subject matters, if available, would give healthcare providers a valuable tool in formulating the best methods to respond to the current disease and prevent the disease from spreading in the future. Method: An extensive literature search on the subjects of COVID-19 was conducted regarding the possible origin of the viral pathogen, its evolutionary changes and health impacts, the world’s responses to COVID-19 and outcomes of their responses, and healthcare professional’s actions to understand and manage the disease and the results of their actions. To gather these data, websites of PubMed and Google Scholar were utilized for the search with the following keywords: Pandemic, COVID-19, coronavirus, SARS, SARS-CoV, SARS-CoV-2, origin, pathogenesis, and treatment. Results: Our review revealed data that points to an interesting autoimmune phenomenon where most seriously sick patients affected by COVID-19 were documented by an IgA-dominant immune response to the pathogen, along with a neutrophil-directed infiltration to the vital organ in the lung aveola, resulting in critical lung injury, leading to respiratory failure, multi-organ failure, and death. Surprisingly, this IgA-mediated and neutrophil-directed disease pattern is nearly identical to a group of IgA-mediated autoimmune skin diseases, such as dermatitis herpetiformis, IgA bullous dermatosis, and IgA pemphigus, which respond well to treatment by dapsone, a sulfone class of antibiotic/anti-inflammatory drug. Moreover, the usefulness of dapsone was supported by a small clinical study. In addition, systemic corticosteroid, a trusted anti-inflammatory medication, has been used in this pandemic with variable degrees of success. Conclusion: The data collected from our review of the subject, together with our prior search knowledge, compel us to conclude that the underlying pathophysiology that causes serious respiratory distress and multi-organ failure is most likely to be autoimmune in nature and that strategies to counter these multifacet autoimmune disorders would be the most valuable in life-saving. Specifically, we identified clinical and laboratory evidence pointing to IgA autoimmune reaction as a key factor that causes significant mortality in many patients. Accordingly, we proposed the utilization of a combination of dapsone, corticosteroid, and anti-thrombotic drugs in severely ill patients at the earliest point of the disease process. The autoimmune multi-organ syndrome may explain the pathogenesis of COVID-19 as well as Post-COVID conditions and may guide healthcare professionals in a better direction to manage the disease. The possible origin of the viral pathogen may shed light on a better understanding of the pathogenesis of the disease.

著作权法上独创性概念的澄清与重释

由于个性、创造性、智力劳动等概念比较抽象,一部作品是否具有独创性通常取决于预设的私人立场。这种判定模式会不合理地损害著作权保护的预期。从我国的作品定义看,独创性是一部作品区别于其他作品的内在尺度。独创性既表明了特定作品的特有属性,又表达了与其相关的权益归属。这一内涵与著作权法的内外价值一致。依此逻辑,独创性是指作品的相对差异,并暗示作品进入市场的机会与作品价值的二分。按照相对差异标准,作者享有依照著作权法提出保护的应然权利。
