Research Progress on Individualized Treatment of Splenic Aneurysm

Splenic artery aneurysm has a hidden onset and atypical symptoms.There are various diagnostic methods for splenic aneurysms,among which ultrasound is the first choice for aneurysm screening.The diagnostic rate of CTA and DSA reaches 100%.In clinical practice,it is necessary to integrate medical history,symptoms and signs,and multiple imaging results to improve the diagnostic rate.In terms of treatment plans,both intervention and surgical procedures have their strengths,and the application of intervention will be more extensive.We need to adhere to the principle of individualization and choose a reasonable treatment plan for patients.At present,there are many reports on pregnant women with large splenic aneurysms both domestically and internationally.Some scholars believe that large splenic aneurysms may be related to hormonal imbalances during pregnancy,and the specific pathogenic mechanism will become a hot topic in future research.

Research Progress of LipiFlow Therapy for Meibomian Gland Dysfunction

Meibomian gland dysfunction(MGD)is a common ocular surface disease,and the pathogenesis of MGD is closely related to the alteration of meibomian gland morphology and(or)function.At present,the treatment strategy for MGD consists of physical therapy,artificial lubricants,topical and systemic antibiotics and antiinflammatory agents,topical steroids andΩ-3 dietary supplementation.Recently,the thermal pulsation system(LipiFlow)has been used clinically,which allows heat to be applied to the palpebral surfaces of the upper and lower eyelids directly over the meibomian glands,while simultaneously applying pulsatile pressure to the outer eyelid surfaces.Due to its specific design,the cornea and eyeball can successfully avoid the potential damage from overheating and improper expression,which will greatly improve the safety during the clinical application and patients'compliance.Studies have showed that the effectiveness of LipiFlow when treating MGD is at least as well as twice-daily lid warming and massage for 3 months,which displays a broad application prospect.At present,the application of LipiFlow in China has not been fully developed,and only some hospitals have experimental applications.This paper summarizes the research progress of LipiFlow treatment in MGD.

Advances in Cervical Artificial Disc Replacement for Cervical Spondylosis

Anterior cervical decompression and fusion(ACDF)treatment for cervical spondylosis has been more than half a century,and achieved good clinical results.However,with the continuous extension of follow-up time,the fusion segment-associated postoperative complications emerged gradually.Reserved cervical stability and activity,the concept of non-fusion was born.As a non-fusion technique,cervical artificial disc replacement(CADR)developed rapidly.With the continuous development of artificial prosthesis materials and design concepts,and specification and proficiency of surgical procedures,CADR has achieved better short and mid-term clinical efficacy than ACDF.Compared with ACDF,the main advantages of CADR are that the postoperative recovery is quick,the activity and stability of cervical vertebra are maintained,the height of cervical intervertebral space is restored,and the stress of adjacent segments and the rate of surgical renovation are reduced.In clinical work,as an emerging technology,CADR requires spine surgeons to control the surgical indications,contraindications,and patients'conditions strictly.This article reviews the research progress of CADR in order to provide new ideas for clinical treatment of cervical spondylosis.

Research Progress on the Prevention of Premature Infant Lung Injury and Neonatal Respiratory Support

In the past 40 years,advances in neonatal intensive care unit(NICU)technology have enabled premature infants with lower birth weight and younger gestational age to survive.But with it comes an increase in the incidence of long-term respiratory dysfunction,mainly in the form of bronchopulmonary dysplasia(BPD).Preventing lung injury is crucial for preventing BPD and improving the long-term prognosis of premature infants.Therefore,how to avoid ventilator-associated lung injury has become a focus of clinical and scientific research in premature infants in recent years.This article will elaborate on the susceptibility and pathophysiology of premature infant lung injury,ventilation strategies for preventing lung injury,and new advances in neonatal respiratory support.

The Effect of Different Hyperbaric Oxygen Treatment Time Windows on Neurological Function and Prognosis in Acute Cerebral Infarction

Objective:To observe the effects of different hyperbaric oxygen treatment time windows on the prognosis and neurological function of acute cerebral infarction.Method:160 patients with acute cerebral infarction admitted to Xiangyang Central Hospital in Hubei Province were randomly divided into four groups,each with 40 cases,using a random number table method.According to the 2017 guidelines for the treatment of cerebral infarction,the control group received routine treatment for acute cerebral infarction;On the basis of the control group,patients in Group A received hyperbaric oxygen therapy within 48 hours of onset;Group B patients receive hyperbaric oxygen therapy within 3-6 days of onset;Group C patients receive hyperbaric oxygen therapy within 7-12 days of onset.Observe the efficacy,recurrence,and neurological function recovery of four groups of patients after treatment.Result:There was no statistically significant difference in the National Institutes of Health Stroke Scale(NIHSS)and Barthel Index(BI)scores among the four groups before treatment(P>0.05).There were statistically significant differences in NIHSS and BI scores between 14 and 30 days after treatment and before treatment(F=16.352,27.261,11.899,28.326,P<0.05).At 14 and 30 days after treatment,the NIHSS score in Group A decreased compared to the control group,Group B,and Group C,while the BI score increased compared to the control group,Group B,and Group C,with statistical significance(P<0.05).There was no statistically significant difference in NIHSS and BI scores between Group C and the control group after treatment(P>0.05).After 30 days of treatment,the total effective rate of Group A was higher than that of the control group and Group C,and the difference was statistically significant(X2=6.135,P<0.05).The one-year recurrence rate of Group A and Group B is lower than that of Group C and the control group,and the difference is statistically significant(X2=8.331,P<0.05).There was no statistically significant difference in adverse reactions among the four groups(P>0.05).Conclusion:Patients with acute cerebral infarction who receive hyperbaric oxygen therapy within 48 hours can improve neurological function and reduce the recurrence rate.The efficacy of receiving hyperbaric oxygen therapy within 7-12 days of onset is equivalent to that of not receiving hyperbaric oxygen therapy.

Research Progress on the Application of Nanomaterials in the Treatment of Oral Cancer

Oral cancer is a complex pathological process caused by a combination of exogenous factors represented by oncoviruses and endogenous factors represented by immune damage,individual DNA damage,and repair.Targeted treatment for oral cancer is based on the perspective of molecular genetics,which can not only reduce toxicity and increase efficacy,but also improve the quality of life of patients.This is the bottleneck that clinical oral cancer treatment needs to break through the most.Nanomaterials can exhibit a unique large molecular surface area,with relatively high surface reactivity and multiple surface active centers,resulting in strong adsorption capacity in molecular metabolism.There is a certain foundation in its application in the field of biology,but it has good tumor cytotoxicity and inhibition of proliferation in the treatment of oral cancer.This study reviews the application of nanomaterials in tumor prevention,treatment,and other fields,providing new ideas for the future treatment of this disease.

Research Progress on Myocardial Protection Strategies

Myocaridial protection aims to salvage myocardium from ischemia and reperfusion injury and to reduce infarct size and its consequences.After more than 30 years of development,the concept of ischemic preconditioning has evolved into"ischemic conditioning",a term that encompasses a number of related endogenous cardioprotective strategies,which can be applied either directly to the heart(ischemic preconditioning or postconditioning)or from afar,for example to a limb(remote ischemic preconditioning,preconditioning,or postconditioning).A variety of cardioprotective therapies have shown promising results in reducing infarct size and improving clinical outcomes in patients with ischemic heart disease.

Research Progress on the Pathogenesis of Primary Enuresis in Children

Nocturnal enuresis(NE)is a common disease in children,commonly known as bedwetting.The International Children's Continence Society(ICCS)defines intermittent urinary incontinence during nighttime sleep in children aged 5 and above as enuresis.Enuresis can be divided into two types:primary nocturnal enuresis(PNE)and secondary nocturnal enuresis(SNE).PNE refers to nocturnal urinary control ability that has never been achieved for more than 6 months in children aged 5 and above with enuresis;SNE refers to the recurrence of enuresis symptoms after a period of more than 6 months of continuous nocturnal urinary control ability.SNE is relatively rare in clinical practice and is often caused by sudden stress events or other diseases such as snoring.Its pathogenesis and treatment are different from PNE.PNE is a multifactorial disease related to genetics,and its pathogenesis is not fully understood.There are not many research and review articles on its pathogenesis.In recent years,there has been significant progress in the epidemiology and pathogenesis of PNE.The following is a summary.

Research Progress on the Relationship between Magnetic Resonance Imaging and Clinical Pathological Characteristics of Liver Cancer

Liver cancer is one of the main malignant tumors in the digestive system.Early detection and treatment have positive significance in improving patient prognosis and reducing mortality.MRI is the main method for liver cancer examination,which mainly uses computers to compare imaging of different energy regions of tumors,observe the density and signal changes of liver cancer,and the degree of tumor enhancement.In particular,various new MRI functional imaging technologies,such as diffusion-weighted imaging,perfusion weighted imaging,delayed imaging,liver cell specific contrast agent enhanced imaging,etc.,can be used at the molecular level Multiple aspects such as cell function provide clinicians with richer diagnostic information.Therefore,further comparative analysis of MRI manifestations and pathological results of liver cancer can help to gain a deeper understanding of the biological behavior of tumors and provide a basis for treatment decision-making and prognosis evaluation.

Clinical Research of Transumbilical Singleport Laparoscopic Treatment For Pediatric Intussusception

Objective:To explore the feasibility and clinical efficacy of single port laparoscopic surgery through the umbilical cord for the treatment of pediatric intussusception.Method:Clinical data of 38 cases of pediatric intussusception treated with umbilical single port laparoscopic surgery from December 2017 to June 2019 were collected.The surgical method involves placing Trocar through the umbilical incision to establish pneumoperitoneum,inserting a single hole with a 0°laparoscopic operating channel,exploring intussusception,and performing non-invasive forceps to completely reduce it.After the reduction of intussusception,if intestinal malformation is found,the umbilical incision can be expanded to lift the diseased intestinal tract out of the abdominal cavity for resection.At the same time,clinical data of 24 children who underwent traditional porous laparoscopic intussusception surgery during the same period were collected,and the surgical time,intraoperative blood loss,postoperative hospital stay,and satisfaction score of incision aesthetics were compared between the two groups of children.Result:Both groups of patients successfully completed the surgery,and compared with the porous laparoscopic group,the single hole laparoscopic group had a shorter surgical time[(32.4±8.6)minutes vs.(40.6±9.8)minutes,P<0.05],decreased bleeding volume[(5.5±1.5)mL vs.(8.6±2.2)mL,P<0.05],significantly shortened postoperative hospital stay[(4.6±1.2)d vs.(6.2±1.4)d,P<0.05],and significantly increased satisfaction score with incision aesthetics[(4.2±0.8)points vs.(3.2±0.7)points,P<0.05].Follow up for 6 months to 2 years showed no recurrence of intussusception.Conclusion:Transumbilical single port laparoscopic surgery is a safe and effective method for children with intussusception,which is characterized by small trauma,fast recovery,short operation time,and better aesthetic effect.

Research Progress on the Influencing Factors and Preventive Interventions of Iron Deficiency

Iron is an important element that maintains the normal operation of the body.It not only participates in various physiological reactions as a component of various enzymes,but also is an indispensable component in the synthesis of hemoglobin(Hb)and myoglobin,which transport oxygen.About two-thirds of the iron in the body is stored in the Hb of red blood cells,with a small amount present in myoglobin in muscle tissue and enzymes required for various metabolic reactions.The remaining amount is mostly in the form of ferritin as a mobilized iron reserve.When dietary iron intake is limited and the stored iron in the body is insufficient or depleted,iron deficiency occurs.Iron deficiency can be further divided into three stages based on their severity,namely iron deficiency(ID),iron deficiency erythropoiesis(IDE),and iron deficiency anemia(IDA).This study aims to explore the prevalence,diagnosis and differentiation,influencing factors,and preventive interventions of iron deficiency.

Research Progress in Brain Metastasis of Breast Cancer

The incidence rate of breast cancer is very high.Some patients were diagnosed as stage IV patients at the first diagnosis and had distant metastasis.Bone,lung and liver are the common metastatic sites of breast cancer.Although brain is the least common metastatic site of breast cancer,the incidence of brain metastasis in newly diagnosed breast cancer patients is increasing year by year.After brain metastasis,the disease develops rapidly,and because of the existence of blood cerebrospinal fluid barrier,it is difficult for drugs to reach the focus,and the curative effect is poor,leading to poor prognosis of patients with brain metastasis of breast cancer.Previous studies have also explored the clinical characteristics of brain metastases from breast cancer and the factors affecting prognosis.Different ages,races,histological grades,T stages,N stages,molecular subtypes,and pathological types are the main factors affecting the occurrence and prognosis of brain metastases from breast cancer.Studies on the characteristics,mechanisms,and treatment plans of brain metastases from breast cancer have also been reported at home and abroad.This article reviews the clinical characteristics,pathogenesis and treatment progress of brain metastases from breast cancer,aiming to provide some ideas and basis for clinical diagnosis and treatment and drug research of brain metastases from breast cancer.

Progress in the Treatment of Thoracolumbar Spinal Fractures with Internal Fixation of Injured Vertebrae with Screws

The thoracolumbar spine,due to its large range of motion and relatively fragile anatomical structure,is prone to traumatic fractures and has become one of the common types of fractures in clinical practice.Thoracic and lumbar fractures may lead to spinal instability,spinal stenosis,etc.,and early restoration of vertebral height and sequence is necessary.Although the technique of transpedicular screw internal fixation for traumatic vertebrae is effective in the short term,in the long run,there may be adverse situations such as fixation breakage and loosening,leading to loss of vertebral height and kyphosis deformity.The technique of internal fixation of injured vertebrae with screws is considered to minimize postoperative complications and is worthy of promotion and use.With the advancement of medical technology,imaging,and biomechanics,the treatment methods for thoracolumbar spinal fractures are becoming increasingly diverse.

The Impact of Cardiac Pacing Site on Patient's Cardiac Function and Psychological State

With the widespread application of artificial permanent pacemakers in clinical practice,there have been new changes in the indications for pacemaker implantation.The current clinical indications include high atrioventricular block,sick sinus syndrome,cardiac resynchronization therapy for heart failure,and implantation of cardioverter defibrillators for ventricular arrhythmias.The implantation of a pacemaker can improve the quality of life and prognosis of patients with arrhythmia.In the past,permanent pacemaker implantation was performed in clinical practice,and the right ventricular pacing electrode was often fixed at the apex of the right ventricle,which belongs to non physiological pacing.Through long-term clinical follow-up,it was found that apex pacing can easily cause abnormal depolarization of the left ventricle,asynchronous contraction of the myocardium,and ultimately lead to myocardial fibrosis,which has adverse effects on the patient's cardiac function and psychological state.In recent years,Scholars have found that pacing in the right ventricular outflow tract septum is closer to the atrioventricular node and closer to the His bundle Purkinje fibers.The pacing impulse almost simultaneously expands towards both ventricles,closer to the physiological pacing state,thereby reducing the occurrence of cardiovascular events in patients.This article explores the impact of pacing in different parts of the heart on the cardiac function and psychological state of patients based on clinical data from the past three years.

Research Progress of Drug Therapy for Diabetes

Diabetes is mainly a series of symptoms of glucose metabolism disorder caused by relative or absolute insufficiencies of insulin.Most patients are accompanied by protein,fat,water and electrolyte disorders,including diabetes type 1 and diabetes type 2,of which diabetes type 2 accounts for more than 90%.The incidence rate of diabetes is high,the course of disease is long,and it is difficult to cure.Most patients need long-term medication.This study analyzed the clinical manifestations and predisposing factors of diabetes,and explored the progress of drug treatment of diabetes,which is summarized as follows.

Research Progress on Conservative Treatment of Lumbar Disc Herniation

Lumbar disc herniation(LDH)is a common orthopedic disease in clinical practice,with main symptoms of varying degrees of pain and functional impairment,seriously affecting the quality of work and life of patients,and also causing a certain degree of economic burden to the patient's family and society.At present,there are various conservative treatment methods for LDH in clinical practice.Conservative treatment has the characteristics of small trauma and high safety,which can achieve symptom relief and cure for most patients in clinical practice.This article aims to provide a scientific reference for the selection of treatment plans for LDH patients by reviewing relevant literature on conservative treatment of LDH that has been publicly reported both domestically and internationally in recent years.

Research Progress on the Etiology,Diagnosis and Treatment of Neonatal Necrotizing Enterocolitis

Necrotizing enterocolitis(NEC)is a leading cause of death from gastrointestinal disease in premature and low-birth-weight infants.Early detection of severely ischemic or necrotic bowel before perforation is rather difficult.New techniques including multi-omics contribute to better understanding its underlying mechanisms and discovering differe categories of biomarkers.Combination of clinical metrics such as seven components of metabolic derangement(CMD)may provide accurate assessment of its severity.Implementation of quality improvement initiatives including breast milk feeding actually lowers its incidence.
