The Process of Tiger Disappearance in Guizhou

In this paper,the authors collected officially published literature on the South China tiger(Panthera tigris amoyensis)in Guizhou from 1900 to 1980,from which we extracted information on its historical distribution and population size,and collected data on the tiger skin trade after 1950,the change in subtropical broad-leaved evergreen forest cover,and demographic data in the relevant databases.GIS mapping was used to visualize the distribution range of the South China tiger in Guizhou Province during the period 1900–1980 and to discuss the history of its disappearance in Guizhou and its driving factors.The results show that in 1900,the South China tiger was distributed throughout 82 cities and counties in nine prefectures and municipalities in the province;the number of documented South China tiger distribution sites in 1900–1950 decreased to 48 compared to 1900;the number of counties with South China tigers in 1950–1980 further decreased and became extinct in some areas;and in the 1990s,the South China tiger became extinct in the wild in Guizhou.The main reasons for the extinction of the South China tiger in the wild in Guizhou are:on the one hand,with the socio-economic development of Guizhou Province,the population has increased dramatically,the magnitude of the demand for natural resources has increased,and in order to satisfy this demand,human activities,such as coal mining and clearing of mountains for planting,have been intensified,resulting in the reduction of the coverage rate of the subtropical broad-leaved evergreen forests,which has resulted in the extreme loss of the habitat of the South China tiger;on the other hand,the insufficient protection efforts and protection measures for this species in the country before the 1980s,which were subjected to anthropogenic hunting,were also factors leading to the extinction of this species in the wild in Guizhou Province.As a big cat at the top of the food chain,the distribution of the South China tiger can reflect the history of the natural environment in the region.By analyzing and discussing the distribution history of the South China tiger population in Guizhou Province,the significance of this case is to provide a scientific basis for the future conservation of biodiversity and the development of ecological restoration measures in the karst mountains of southern China.

Application effect of phloroglucinol injection in elderly patients with spastic abdominal pain in emergency department

BACKGROUND Although norepinephrine injection is commonly used in emergency situations,it is associated with risks for elderly patients with spasmodic liver pain.This study explores the safety and effectiveness of mebendazole injection,an alternative treatment option,for the emergency management of spasmodic abdominal pain,while minimizing adverse reactions,in elderly patients.AIM To explore the development of norepinephrine injection and the adverse reactions of this drug in emergency elderly patients with spasmodic liver pain.METHODS The control group consisted of 56 elderly patients visiting our hospital from January 2021 to December 2021.After hospital admission,the control group was intravenously administered tolopin.The experimental group consisted of 56 emergency patients with spasmodic abdominal pain who visited our hospital until June 2022.After hospital admission,the experimental group was intravenously administered toloxazole.The two groups were treated for 3 d.The disappearance of clinical symptoms was observed before and after the treatment,and the difference in adverse reactions between the two groups was compared.RESULTS The pain of the wife,fire,diarrhea,drowning,and surrounding time disappeared in the experimental group.No statistical difference was observed between the experimental and control groups in visual pain analog scale(VAS)scores before and after the treatment(P>0.05).The VAS scores of abdominal pain severity after 0.5 h,1.0 h,and after 6.0 h of treatment were significantly lower for the experimental group than for the control group.After the treatment,the therapeutic effect in the experimental group was higher and statistically significant than that in the control group(P<0.05).The probability of adverse reactions before the treatment was lower in the experimental group than in the control group.CONCLUSION During emergency,mebendazole injection exhibited a good therapeutic value when used for the clinical treatment of elderly patients with spasmodic stomach pain.It accelerated the disappearance of clinical symptoms such as stomach pain,reduced the stomach weight,and improved clinical activity.Reducing and promoting the frequency of high treatment safety with mebendazole injection is worthwhile.

Who is in the Lower Reaches,Who Suffers Disasters?——Take Minqin County,a Disappearing Oasis as a Case

Minqin Oasis is located in the lower reaches of the Shiyanghe River Basin, northeast of the Heixi Corridor, at the middle of the Silk Road. Because of the its existence, Badain Jaran Desert and Tengger Desert cannot converge and develop in the south. It has always been an important green barrier to guarantee the eco-security of Hexi Corridor and the Silk Road for thousands of years. But in recent decades, Minqin Oasis is becoming smaller and the desert is becoming larger. Many people, especially the governmental officials in the lower reaches think that the upper and middle reaches have robbed the lower reaches of water resources, and caused insufficient water usage and the deteriorated eco-environment, in the lower reaches, However, the governmental officials in the upper and middle reaches claim that the whole river basin should take the upper and middle reaches as the key regions to develop economy. To address the above argument, we analyze the reasons why Minqin Oasis is disappearing, and find that there are two main factors. One is the quick development of population and economy in the upper and middle reaches; the other is the rapid development of population and economy in the lower reaches. The two factors both have great effect on the water utilization for eco-environment in the lower reaches. So Minqin Oasis is disappearing not only because of the upper and middle reaches but also because of the growth of population and economy itself. The lower reaches should not completely blame the upper and middle reaches. The upper and middle reaches should also pay more attention to the eco-environment in the lower reaches. The whole river basin should develop a harmonious and sustainable relationship among the upper, middle and lower reaches.

Neoadjuvant chemotherapy for colorectal liver metastases:A contemporary review of the literature

Colorectal carcinoma(CRC)is one of the leading causes of cancer-related deaths worldwide,and up to 50%of patients with CRC develop colorectal liver metastases(CRLM).For these patients,surgical resection remains the only opportunity for cure and long-term survival.Over the past few decades,outcomes of patients with metastatic CRC have improved significantly due to advances in systemic therapy,as well as improvements in operative technique and perioperative care.Chemotherapy in the modern era of oxaliplatin-and irinotecancontaining regimens has been augmented by the introduction of targeted biologics and immunotherapeutic agents.The increasing efficacy of contemporary systemic therapies has led to an expansion in the proportion of patients eligible for curative-intent surgery.Consequently,the use of neoadjuvant strategies is becoming progressively more established.For patients with CRLM,the primary advantage of neoadjuvant chemotherapy(NCT)is the potential to down-stage metastatic disease in order to facilitate hepatic resection.On the other hand,the routine use of NCT for patients with resectable metastases remains controversial,especially given the potential risk of inducing chemotherapy-associated liver injury prior to hepatectomy.Current guidelines recommend upfront surgery in patients with initially resectable disease and low operative risk,reserving NCT for patients with borderline resectable or unresectable disease and high operative risk.Patients undergoing NCT require close monitoring for tumor response and conversion of CRLM to resectability.In light of the growing number of treatment options available to patients with metastatic CRC,it is generally agreed that these patients are best served at tertiary centers with an expert multidisciplinary team.

GUIDED CIRCUMFERENTIAL WAVES IN DOUBLE-WALLED CARBON NANOTUBES

A model of guided circumferential waves propagating in double-walled carbon nanotubes is built by the theory of wave propagation in continuum mechanics, while the van der Waals force between the inner and outer nanotube has been taken into account in the model. The dispersion curves of the guided circumferential wave propagation are studied, and some dispersion characteristics are illustrated by comparing with those of single-walled carbon nanotubes. It is found that in double-walled carbon nanotubes, the guided circumferential waves will propagate in more dispersive ways. More interactions between neighboring wave modes may take place. In particular, it has been found that a couple of wave modes may disappear at a certain frequency and that, while a couple of wave modes disappear, another new couple of wave modes are excited at the same wave number.

CLINICAL OBSERVATIONS ON 278 CASES OF CERVICAL SPONDYLOPATHY TREATED WITH ELECTRO ACUPUNCTURE AND MASSOTHERAPY

From Dec. 1990 to Dec. 1993, 278 cases of cervical spondylopathy were treated with electroacupuncture and massotherapy. The cure rate was 82.7%; but in the control group, it was only 61%, indicating that electroacupuncture may enhance the cure rate (P【 0.05). Of the 278 cases treated by three to five sessions, the pain and numbness disappeared in about 96% of the patients.

Reading Text Under Normal and Disappearing Presentation Conditions

In this article I discuss data from a series of experiments in which readers’ eye movements were recorded as they processed sentences in which each word disappeared or was masked 60ms after fixation onset. We used this paradigm to investigate whether we could induce a gap effect during reading, and how visual and linguistic factors affected eye movements under these conditions. The data showed that no gap effect occurred in our experiment. Overall reading times were the same under normal and disappearing presentation conditions. However, readers did adopt a strategy of making fewer but longer fixations when the text disappeared than when it did not. Additionally, clear frequency effects occurred regardless of whether the text was presented normally or disappeared. This finding indicates that while the visual uptake of information is important, cognitive processes associated with the lexical identification of words are a primary influence on when readers move their eyes during reading. The findings are taken to support the E-Z Reader model of eye movement control.

Rapid spontaneous resolution of lumbar ganglion cysts: A case report

BACKGROUND To discuss the rare event of spontaneous resolution of a lumbar ganglion cyst,a personal case report and 25 cases culled from the literature were described in detail.We focused on demographic,classification,clinical and radiological findings,treatment,outcome and radiological resolution.CASE SUMMARY A 51-year-old man presented to our observation with complaints of low back and right leg pain.Lumbar magnetic resonance imaging(MRI).showed a L4-L5 ganglion cyst.The patient was referred to medical therapy and bracing.After 4 wk,he showed a complete resolution of pain.The complete spontaneous resolution of the cyst was demonstrated by the followed-up MRI.CONCLUSION Spontaneous resolution of lumbar ganglion is very rare and only 26 cases,including ours,were reported in literature.Different degrees of biomechanical impairment seem to play a fundamental role in the pathogenesis.Related symptoms are essentially represented by low back and/or radicular pain,without significant neurological disorders.Anti-inflammatory drugs,light unloading exercises and brace could be recommended to administrated pain and decrease facet loads.Mean time for clinical improvement was 7 mo,while MRI disappearance occurred in an average time of 11 mo.Therefore,surgery should be applied when conservative treatment,prolonged at least 6 mo,fails.

Disappearance of unaffected motor cortex activation by repetitive transcranial magnetic stimulation in a patient with cerebral infarct

The ipsilateral motor pathway from the unaffected motor cortex to the affected extremity is one of the motor recovery mechanisms following stroke （Jang, 2011）. Because stroke patients who had shown recovery by this mechanism usually showed poorer motor function, compared with patients who showed recovery by other mechanisms, several researchers have considered this mechanism as a maladaptive plasticity （]ang, 2013）.

Prosperity and Disappearance of Introduced Fishes in Xiangmoshan Reservoir

In order to enhance the resources, some fishes were introduced into Xiangmoshan reservoir. The introduced fishes consisted of different ecotypes such as silver carp （Hypophthahnichthys rnolitrix （Cuvier et Valenciennes））, big head （Aristichthys nobilis （Richardso）） and lake herring （Coregonus clupeaformis （Mitchill）） that were plankton feeders, common carp （Cyprinus carpio Linnaeus） and crucian carp （Carassius auratus gibelio） belonging to the polyphagia, and also the non-native predator Walleye （Stizostedion vitreum （Mitchill）） and big mouth （Silurus soldatovi rneridonalis Chen）, et al. Among there were not only the cool water fish Peled （Coregonus peled （Gmelin））, but also the warm water fish big mouth. The introduction of non-native fishes resulted in ecosystem changes of the reservoir and some native fishes had gone to decrease their population sizes or been in the condition of depopulation such as Opsariichthys uncirostris arnurensis （Berg）, Rhodeus sericeus （Pallas） and Silurus asotus （Linnaeus）. The native common carp had disappeared after the introduction of non-native species. Roach （Rutilus rutilus lacustris （Pallas） had been thriven for one or two generations after its introduction and immeidiatly disappeared. Silver fish （Protosalanx hyalocranius （Abbott））, Lake herring （Coregonus clupeaformis （Mitchill）） and Walleye （Stizostedion vitreum （Mitchill）） died several years after the introduction, so most of the introduced species has passed out of existence. Via many years introduction of different fishes, composition of species and the structure of the population in the reservoir had been changed obviously. It was necessary to further estimate whether the ecosystem of the reservoir had been damaged.

Nonautonomous solitons in the continuous wave background of the variable-coefficient higher-order nonlinear Schro¨dinger equation

We reduce the variable-coefficient higher-order nonlinear Schrodinger equation （VCHNLSE） into the constantcoefficient （CC） one. Based on the reduction transformation and solutions of CCHNLSE, we obtain analytical soliton solutions embedded in the continuous wave background for the VCHNLSE. Then the excitation in advancement and sustainment of soliton arrays, and postponed disappearance and sustainment of the bright soliton embedded in the background are discussed in an exponential system.

Ruminal in situ disappearance kinetics of six nutritive ingredients in leaves and stems of young tetraploid black locust in growing steers

Tetraploid black locust （Robinia pseudoacacia） is a woody plant with larger leaves and richer nutritional content than normal diploid black locust, with greater biomass and wider adaptability than herbaceous plant forage. However, currently no stock- breeders have adopted it as a major forage in China and other countries for a lack of information on the evaluation of nutritional ingredients of leaves and stems of young tetraploid black locust （YTBL） by in situ digesting tests. The objectives of this study were： 1） to assess the nutritive value of YTBL that bourgeoned from root stumps in the spring by determining the ruminal in situ disappearance kinetics of dry matter （DM）, organic matter （OM）, crude protein （CP）, ether extract （EE）, neutral detergent fiber （NDF） and acid detergent fiber （ADF） from leaves, stems and a mixture of both leaves and stems （MLS） of YTBL; 2） to compare these kinetic estimates with those of Leymus chinensis, a widely used ruminant forage in China. All samples were evaluated in situ by using five ruminally cannulated crossbred steers （550±22.7 kg BW）. The results of 48 hours, the representative incubation period, indicate that in situ disappearance rates of DM and OM in YTBL leaves, stems and MLS are on average about 40% and can attain the level of digestibility of L. chinensis. In situ disappearance rates of leaves, stems and MLS of YTBL for CP and EE were 41% and 58% respectively, rates higher than those of L. chinensis. But the disappearance rates of NDF and ADF were, on average, respectively 30.62% and 24.89% and lower than those ofL. chinensis. By analyzing synthetically all of our results it could be inferred that MLS of YTBL offers effective ruminal degradability of DM, NDF, ADF, CP, EE and OM, similar to the nutrients of L. chinensis. This supports our contention that the YTBL leaves, stems and MLS are suitable feed for those ruminants requiring high levels of nutrients, such as dairy cows and Boer goats, instead of plant forage, which is decidedly lacking in some parts of the world.
