Incidence and Management of Occupational Blood Exposure (OBE) among Medical Students at the University of Bangui

Introduction: Like healthcare workers, medical students are also exposed to a risk of accidental contamination during their hospital internships. However, they do not benefit from prevention services in the same way as workers in this sector, although they actively participate in the routine care provided to patients in the various hospital departments. The objective of our study is to determine the incidence of these accidents and their medical and administrative management among these victims (medical students) not classified in the category of workers. Materials and Method: This was a cross-sectional study carried out over three months from January 15 to March 14, 2023. The study population consisted of all medical students at the Faculty of Health Sciences at the University of Bangui. Regularly enrolled students from 2nd to 7th year, on placement in hospitals in the Central African Republic and who gave their informed consent were included. Data were collected through a self-administered questionnaire. Results: A cross-sectional study was carried out among medical students concerning the incidence and management of accidents involving exposure to blood in the Central African Republic. Of the 254 students included, three (9%) had already been correctly vaccinated against the viral hepatitis B virus, 198 (77.9%) reported still having access to personal protective equipment, 133 students (52.4%) reported being victims of OBE in the past 12 months. The main types of OBE were stings (62%), followed by liquid splashes (32%) and cuts (6%). Among the 133 victims, 92.9% carried out immediate hand disinfection or abundant eye washing, 41.9% obtained the serology of the source patient and 37% reported the accident to their supervisor. Conclusion: It is important that students benefit from better prevention and management of these accidents.

In silico evidence of Remdesivir action in blood coagulation cascade modulation in COVID-19 treatment

BACKGROUND Coronavirus disease 2019(COVID-19)has demonstrated several clinical manifestations which include not only respiratory system issues but also liver,kidney,and other organ injuries.One of these abnormalities is coagulopathies,including thrombosis and disseminated intravascular coagulation.Because of this,the administration of low molecular weight heparin is required for patients that need to be hospitalized.In addition,Remdesivir is an antiviral that was used against Middle East Acute Respiratory Syndrome,Ebola,Acute Respiratory Syndrome,and other diseases,showing satisfactory results on recovery.Besides,there is evidence suggesting that this medication can provide a better prognosis for patients with COVID-19.AIM To investigate in silico the interaction between Remdesivir and clotting factors,pursuing a possibility of using it as medicine.METHODS In this in silico study,the 3D structures of angiotensin-converting enzyme 2(ACE2),Factor I(fibrinogen),Factor II(prothrombin),Factor III(thromboplastin),Factor V(proaccelerin),Factor VII(proconvertin),Factor VIII(antihemophilic factor A),Factor IX(antihemophilic factor B),Factor X(Stuart-Prower factor),and Factor XI(precursor of thromboplastin(these structures are technically called receptors)were selected from the Protein Data Bank.The structures of the antivirals Remdesivir and Osetalmivir(these structures are called ligands)were selected from the PubChem database,while the structure of Atazanavir was selected from the ZINC database.The software AutoDock Tools(ADT)was used to prepare the receptors for molecular docking.Ions,peptides,water molecules,and other ones were removed from each ligand,and then,hydrogen atoms were added to the structures.The grid box was delimited and calculated using the same software ADT.A physiological environment with pH 7.4 is needed to make the ligands interact with the receptors,and still the software Marvin sketch®(ChemAxon®)was used to forecast the protonation state.To perform molecular docking,ADT and Vina software was connected.Using PyMol®software and Discovery studio®software from BIOVIA,it was possible to analyze the amino acid residues from receptors that were involved in the interactions with the ligands.Ligand tortions,atoms that participated in the interactions,and the type,strength,and duration of the interactions were also analyzed using those software.RESULTS Molecular docking analysis showed that Remdesivir and ACE2 had an affinity energy of-8.8 kcal/moL,forming a complex with eight hydrogen bonds involving seven atoms of Remdesivir and five amino acid residues of ACE2.Remdesivir and prothrombin had an interaction with six hydrogen bonds involving atoms of the drug and five amino acid residues of the clotting factor.Similar to that,Remdesivir and thromboplastin presented interactions via seven hydrogen bonds involving five atoms of the drug and four residues of the clotting factor.While Remdesivir and Factor V established a complex with seven hydrogen bonds between six antiviral atoms and six amino acid residues from the factor,and Factor VII connected with the drug by four hydrogen bonds,which involved three atoms of the drug and three residues of amino acids of the factor.The complex between Remdesivir and Factor IX formed an interaction via 11 hydrophilic bonds with seven atoms of the drug and seven residues of the clotting factor,plus one electrostatic bond and three hydrophobic interactions.Factor X and Remdesivir had an affinity energy of-9.6 kcal/moL,and the complex presented 10 hydrogen bonds and 14 different hydrophobic interactions which involved nine atoms of the drug and 16 amino acid residues of the clotting factor.The interaction between Remdesivir and Factor XI formed five hydrogen bonds involving five amino acid residues of the clotting factor and five of the antiviral atoms.CONCLUSION Because of the in silico significant affinity,Remdesivir possibly could act in the severe acute respiratory syndrome coronavirus 2 infection blockade by interacting with ACE2 and concomitantly act in the modulation of the coagulation cascade preventing the hypercoagulable state.

Endovascular treatment of blood blister-like aneurysms in the internal carotid artery using a Willis covered stent

Background Despite the current availability of flow diverter devices(FDD), problems remains regarding optimal endovascular treatment(EVT) for blood blister-like aneurysms(BBAs) of the internal carotid artery(ICA). Objective To evaluate the safety and efficacy of EVT of BBAs in the ICA with a Willis covered stent. Methods 20 consecutive patients(5 men and 15 women) with ruptured BBAs underwent EVT using a Willis covered stent in two institutions from March 2013 to March 2018. Clinical observations, angiographic characteristics, and procedural and follow-up outcomes were retrospectively evaluated. Results 20 consecutive patients(5 men and 15 women) with ruptured BBAs underwent EVT using a Willis covered stent in two institutions from March 2013 to March 2018. Clinical observations, angiographic characteristics, and procedural and follow-up outcomes were retrospectively evaluated. Conclusion Our initial results demonstrate that reconstructive EVT using a Willis covered stent provides a viable approach to treat ICA BBAs. However, an expanded clinical evaluation and larger cohort are needed to confirm the results.

Vein transplantation using human umbilical cord blood stem cells in the treatment of stroke sequela

BACKGROUND: Transplanted mononuclear cell (MNC) of umbilical blood can survive in central nervous system (CNS) of host through blood brain barrier, differentiate into nerve cells, migrate to damaged site and integrate morphological structure and function with nerve cells of host so as to improve deficiencies of sensatory function, motor function and cognitive function and influence on stroke sequela. OBJECTIVE: To observe the vein transplantation of human umbilical cord blood stem cells (HUCBSC) for improving neurological function, limb function and activity of daily living of patients with stroke and evaluate the reliability. DESIGN: Self-controlled study. SETTING: Department of Neurosurgery, the Second People's Hospital of Zhengzhou City; Red-crossed Blood Center of Henan Province; Department of Neurosurgery, the Fist Affiliated Hospital of Zhengzhou University. PARTICIPANTS: A total of 10 patients with stroke sequela were selected from Department of Cerebral Surgery, the Second People's Hospital of Zhengzhou City from April to December 2005. There were 9 males and 1 female aged from 35 to 75 years with the mean age of 56 years. All of them were diagnosed with CT and MRI examination and coincidence with diagnostic criteria of stroke established by the Fourth National Academic Meeting for Cerebrovascular Disease. All patients provided informed consent. METHODS: 80-140 mL umbilical blood of term birth of newborn was selected hermetically and maintained in sterile plastic bag. And then, the blood was centrifugated at the speed of 1 500 r/min for 30 minutes at 22 ℃ in order to separate MNC, i.e., HUCBSC. In addition, after final diagnosis during hospitalization, stroke patients were perfused with HUCBSC through superficial vein of back of the hand. Each patient was averagely perfused with 6 portions of HUCBSC (cellular numbers ≥ 1×108/portion) and the interval between each portion was 1-7 days with the mean interval of 4 days. MAIN OUTCOME MEASURES: ① Neurological function of stroke patients was evaluated with neurological function deficiency (NFD) before treatment and at 3 months after treatment. The scale includes consciousness, level fix function, facial paralysis, language, muscle force of upper limbs, muscle force of lower limb and step function. The total scores ranged from 0 to 45; meanwhile, the lower the scores were, the better the neurological function was. ② Motor function of injured limbs was evaluated with Fugl-Meyer Assessment (FMA), including motor function of upper limbs, motor function of lower limbs, balance ability, sensory function and motion of joint. The total scores ranged from 0 to 226; meanwhile, the higher the scores were, the better the motor function of limbs was. ③ Activities of daily living (ADL) was evaluated with Barthel Index (BI), including having meals, taking a bath, dressing oneself, putting on clothes, walking in balance and stair activity. The total scores ranged from 0 to 100; meanwhile, the higher the scores were, the stronger the ADL was. RESULTS: A total of 10 patients were involved in the final analysis. After treatment, NFD of stroke patients was (10.9±5.09) points, which was lower than that before treatment [(25.4±6.09) points, t =8.213, P < 0.01]. In addition, after treatment, FMA and BI of stroke patients were (80.9±25.00) points and (81.1±15.93) points, respectively, which were higher than those before treatment [(31.9±21.85) points, (36.2±19.41) points, t =13.024, 13.670, P < 0.01]. Immuno-suppressive drugs were not used during the whole therapeutic procedure; moreover, immunological rejection and allergic reaction were not observed during the same period. CONCLUSION: Transplanting HUCBSC through superficial vein of back of the hand is regarded as a simple and safe method for the treatment of stroke sequela.

TCM Treatment of Rheumatoid Arthritis by Supplementing the Kidney and Invigorating the Blood Circulation

The therapeutic effects in treating the intermediate and late rheumatoid arthritis by supplementing the kidney and invigorating blood circulation were observed. In the 43 cases of the treatment group, No. 2 Qu Feng Shi Ling capsules (祛风湿灵胶囊2号) and Fenbid (芬必得) were prescribed, while in the 39 cases of the control group Lei Gong Teng Tablets (雷公藤总甙片) and Fenbid were given. The results showed that the total effective rate in the treatment group was more satisfactory than that in the control (P<0.05 or P<0.01). With less toxic effects, the former could better improve the local swelling and lower the blood viscosity.

Involvement of blood mononuclear cells in the infertility, age-associated diseases and cancer treatment

Blood mononuclear cells consist of T cells and monocyte derived cells. Beside immunity, the blood mononuclear cells belong to the complex tissue control system(TCS), where they exhibit morphostatic function by stimulatingproliferation of tissue stem cells followed by cellular differentiation, that is stopped after attaining the proper functional stage, which differs among various tissue types. Therefore, the term immune and morphostatic system(IMS) should be implied. The TCS-mediated morphostasis also consists of vascular pericytes controlled by autonomic innervation, which is regulating the quantity of distinct tissues in vivo. Lack of proper differentiation of tissue cells by TCS causes either tissue underdevelopment, e.g., muscular dystrophy, or degenerative functional failures, e.g., type 1 diabetes and age-associated diseases. With the gradual IMS regression after 35 years of age the gonadal infertility develops, followed by a growing incidence of age-associated diseases and cancers. Without restoring an altered TCS function in a degenerative disease, the implantation of tissue-specific stem cells alone by regenerative medicine can not be successful. Transfused young blood could temporarily restore fertility to enable parenthood. The young blood could also temporarily alleviate aging diseases, and this can be extended by substances inducing IMS regeneration, like the honey bee propolis. The local and/or systemic use of honey bee propolis stopped hair and teeth loss, regressed varicose veins, improved altered hearing, and lowered high blood pressure and sugar levels. Complete regression of stage Ⅳ ovarian cancer with liver metastases after a simple elaborated immunotherapy is also reported.

Effects of Mild Hyperthermia Treatment Using Nano-Mist Sauna on Blood Gas Parameters and Skin Appearance

Physicians often observe patients’ complexion (their natural skin color) as an indicator of health. The complexion may depend on the internal environment, however, very few researchers studied its evidence. We previously reported various benefits of a mild hyperthermia treatment on human health using the nano-mist sauna (NMS), including acceleration of gas exchange (O2 and CO2) in the venous blood, enhancement of immunity, and the modulation of autonomic nervous system. However, the effects of NMS on skin appearance are unknown. There is a historical and widespread belief that mild hyperthermic treatments such as hot springs are good for improving skin appearance. However, the effect of NMS on the skin appearance has not been examined. In the present study, we examined the color of venous blood using the CIELAB (a color space specified by the French Commission internationale de l’éclairage) method, and then compared the color changes before and after NMS stimulation. Next, we examined correlations of blood gas parameters with color elements of the venous blood, which are highly dependent on oxygen. Our results suggest that the colors and appearance of the face depend on the internal environment, because there are numerous vessels under the skin. Thus, the color of the venous blood may provide medical evidence of changes in complexion. This new method may be useful for assessment of medical complexion by physicians, for use in determining internal health based on skin color information.

Application of Stone Needle Therapy Based on Blood Stasis Theory in the Treatment of 36 Cases of Knee Osteoarthritis in Early and Middle Stage

Objective:To evaluate the clinical efficacy of stone needle therapy based on blood stasis theory for different traditional Chinese medicine(TCM)syndrome types of patients with knee osteoarthritis in early and middle stage.Methods:Totally 36 patients with knee osteoarthritis were enrolled in the orthopaedic ward between March 2016 and December 2017,and diagnosed as qi stagnation and blood stasis syndrome,cold dampness and stasis syndrome,or phlegm and stasis syndrome according to TCM syndrome differentiation.After treatment,stone needle was used for ironing on the different meridian acupoints according to different syndrome.The efficacy of patients with the above three syndromes was respectively evaluated,and the visual analogue scale(VAS)score and western ontario and mcMaster universities arthritis Index(WOMAC)score of the three groups were calculated before treatment,2 weeks,and 4 weeks after treatment.Results:The effective rates of the three groups were 86.67%,81.82%,and 80.00%,respectively.After 2 weeks and 4 weeks of treatment,the VAS and WOMAC scores of the three groups decreased significantly compared to treatment before(P<0.05).Conclusion:Stone needle therapy for ironing on the acupoints around the knee joint has a good therapeutic effect on knee osteoarthritis of different syndrome types,which is worthy of further application.

Treatment of hyperbilirubinemia with blood purification in China

The incidence of hyperbilirubinemia is high clinically, which is difficult to cure by medication, surgery or interventional therapies. Non-bioartificial liver is the main alternative in the blood purification for hyperbilirubinemia, which includes plasma exchange, hemoperfusion, hemodialysis, molecular adsorbent recycling system and so on. The research results and clinical experiences in China show that these methods are effective in lowering high levels of bilirubin with fewer side effects. The hyperbilirubinemias of different causes, with different complications or accompanying different diseases can be treated by different methods. Bioartificial liver, hybrid artificial liver support system and adsorbent membrane material have also been studied and their development in reducing hyperbilirubinemias has been achieved. This article gives a brief overview on the actuality and research improvement in blood purification for hyperbilirubinemia in China.

Interventional treatments for hepatic hemangioma:A state-of-the-art review

Hepatic hemangiomas(HHs)are the most common benign tumors of the liver.These tumors are mainly asymptomatic and do not require treatment.Nevertheless,there are some special cases that require therapeutic intervention,and surgery and intervention are currently the primary treatment modalities.Despite significant advances in the development of minimally invasive techniques and their popularization,interventional treatment of HH is still the preferred choice.In the present review,we discuss the pathological properties,type of blood supply,and treatment indications for HH and assess the status and progress of the existing interventional treatments.

Compared with before treatment, the depth of suprapatellar sac effusion in the Qi stagnation and blood stasis type group decreased after treatment (P Conclusion: Musculoskeletal contrast-enhanced ultrasonography was used to quantitatively evaluate the efficacy of TCM external therapy on KOA for different TCM constitutions. Dynamic observation of synovial lesions of knee osteoarthritis provides a valuable imaging method for evaluating the efficacy of traditional Chinese medicine.

Genetically modified human umbilical cord blood cells as a promising strategy for treatment of spinal cord injury

Spinal cord injury （SCI） continues to be a pressing health and social problem. The injury leads to neuronal and glial cell death accompanied by degeneration of nerve fibers. There are currently no particularly effective treatments. SCI causes profound disabil- ity of people affected and has attracted increased attention in the international field of neuroregeneration. For the past two decades, much hope has been placed in cell therapies for the restoration of both structure and function of the injured spinal cord. Embryonic and neural stem cells, olfactory ensheathing cells, microglia-like cells, Schwann cells, mesenchymal stem cells.

Therapeutic strategies for gastroenteropancreatic neuroendocrine neoplasms: State-of-the-art and future perspectives

Although gastroenteropancreatic neuroendocrine neoplasms(GEP-NENs)have always been considered rare tumors,their incidence has risen over the past few decades.They represent a highly heterogeneous group of neoplasms with several prognostic factors,including disease stage,proliferative index(Ki67),and tumor differentiation.Most of these neoplasms express somatostatin receptors on the cell surface,a feature that has important implications in terms of prognosis,diagnosis,and therapy.Although International Guidelines propose algorithms aimed at guiding therapeutic strategies,GEP-NEN patients are still very different from one another,and the need for personalized treatment continues to increase.Radical surgery is always the best option when feasible;however,up to 80%of cases are metastatic upon diagnosis.Regarding medical treatments,as GEP-NENs are characterized by relatively long overall survival,multiple therapy lines are adopted during the lifetime of these patients,but the optimum sequence to be followed has never been clearly defined.Furthermore,although new molecular markers aimed at predicting the response to therapy,as well as prognostic scores,are currently being studied,their application is still far from being part of daily clinical practice.As they represent a complex disease,with therapeutic protocols that are not completely standardized,GEP-NENs require a multidisciplinary approach.This review will provide an overview of the available therapeutic options for GEP-NENs and attempts to clarify the possible approaches for the management of these patients and to discuss future perspectives in this field.

The transition and current pattern of drug therapy for advanced gastric cancer

Gastric cancer is one of the most common malignant tumors in the world.Its incidence ranks fifth among all malignant tumors worldwide and is the third leading cause of death among cancer patients.Surgery is currently considered to be the only radical treatment.However,the low rate of early diagnosis means that most patients have an advanced-stage disease at diagnosis which lost the chance of surgery.Therefore,the main treatment for advanced gastric cancer includes chemotherapy,targeted therapy,immunotherapy.The purpose of this study is to review the transition and current patterns of drug therapy for advanced gastric cancer and to provide assistance for subsequent clinical studies in advanced gastric cancer.

The Flow Behavior of Red Blood Cell Reduced Deformability in Microchannel

Blood cells are mainly(~99%)comprised of red blood cells.The most remarkable properties of are their high deformability,which allow they flow through microcapillaries of diameter even smaller than their size.The RBC’s remarkable mechanical properties originate from the unique architecture of its membrane.To study the mechanism of RBC’s deformability,a commonly adopted approach is to localize the cytoskeleton protein by immunofluorescence,followed by exploring the changes of cytoskeleton protein during cell deformation.During this process,the fixed treatment of RBC using GA and PFA is of great importance.However,RBC’s deformability is reduced by the fixation process and skeletal protein of membrane is changed accordingly.The flow behavior of red RBCs through the microchannel also changed.Given the difficulty of observing RBC flow in vivo,in vitro simulation by virtue of microfluidic devices provides a feasible alternative.An important physiological phenomenon of the blood flow is the formation of cell free layer(CFL),with RBCs show a tendency to concentrate towards the central axis of the pipeline and move faster than the plasma layer.However,this phenomena is weaken if the stiffness of the membrane increase,which occurs in some disease,such as hereditary spherocytosis and hereditary elliptocytosis.To study the effects of GA and PFA fix treatment on RBC deformability,a microfluidic platform is employed to measuring the CFL and flow velocity of blood flow in this work.The PDMS micro flow channel used is 100 micrometers in width and 50 micrometers in deep.The RBC suspension is fed into the flow channel by the injection pump(NE-1000.USA),and the experiments are observed and recorded by the inverted microscope(IX70,Olympus,Japan)and high-speed camera(Memrecam GX-1,NAC,Japan)system.Three GA concentrations,i.e.,0.000 5,0.000 75,and 0.001 wt.%were used.Meanwhile,the effect of PFA at a concentration of 2wt.%work with GA was also investigated.Images of the flowing RBCs are processed mainly based on Memrecam GXLink.The results show that,the diameter of the RBC be treated is bigger and the shape of the RBC is became more flat after treated.Some of RBCs lost their biconcave structure.When the RBC suspension with 5%Hct flow in the microchannel,the CFL thickness decrease after being treated.And with concentrations of GA increase,the CFL thickness become thinner.The CFL thickness decrease significantly when GA and 2 wt.%PFA work combined.The velocity of RBCs decreases after treated with the GA or/and 2wt.%PFA.GA is known to relieve the dissolution of red blood cells during fluorescence labeling.On the other hand,the crosslinking of the aldehyde group(-cho)of GA with the amino group(-nh2)of RBC membrane protein will change the conformation of the membrane protein and its visco-elastic properties in turn.Then,the transparent fluidity orrheology characteristics of RBC is altered.Since GA and PFA are commonly used to immobilize red blood cells and keep the fluorescence constant,and PFA works similarly as GA,as a result,the variation of membrane protein conformation is intensified,and the membrane becomes stiffer.

Rationale,design and baseline patient characteristics of the optimal type 2 diabetes management including benchmarking and standard treatment study in Greece

AIM:To describe baseline data of the optimal type2 diabetes management including benchmarking and standard treatment(OPTIMISE)study in Greece.METHODS:"Benchmarking"is the process of receiving feedback comparing one’s performance with that of others.The OPTIMISE(NCT00681850)study is a multinational,multicenter study assessing,at a primary care level,whether using"benchmarking"can help to improve the quality of patient care,compared with a set of guideline-based reference values("non-benchmarking").In the Greek region,797 outpatients(457men,mean age 63.8 years)with type 2 diabetes were enrolled by 84 office-based physicians.Baseline characteristics of this population are presented.RESULTS:Hypertension was the most prevalent concomitant disorder(77.3%)and coronary heart disease was the most frequent macrovascular complication of diabetes(23.8%).Most patients were overweight or obese(body mass index 29.6±5 kg/m2),exhibiting mostly abdominal obesity(waist circumference102.6±13.6 cm).Biguanides were the most prevalent prescribed drugs for the management of diabetes(70.1%of all prescriptions),whereas statins(93.5%of all prescriptions)and angiotensin receptor blockers(55.8%of all prescriptions)were the most prevalent prescribed drugs for hyperlipidemia and hypertension,respectively.Only 37.4%of patients were on aspirin.Despite treatment,pre-defined targets for fasting plasma glucose(<110 mg/dL),glycated hemoglobin(<7%),systolic blood pressure(<130 mmHg and<125mmHg for patients with proteinuria)and low density lipoprotein cholesterol levels(<100 mg/dL and<70mg/dL for patients with coronary heart disease)were reached in a relatively small proportion of patients(29%,53%,27%and 31%,respectively).In a Greek population with type 2 diabetes,the control of glycemia or concomitant disorders which increase cardiovascular risk remains poor.CONCLUSION:Despite relevant treatment,there is a poor control of diabetes,hypertension and hyperlipidemia in Greek outpatients with type 2 diabetes.

Clinical comprehensive treatment protocol for managing diabetic foot ulcers:A retrospective cohort study

BACKGROUND Diabetic foot ulcers(DFUs)are a common complication of diabetes,often leading to severe infections,amputations,and reduced quality of life.The current standard treatment protocols for DFUs have limitations in promoting efficient wound healing and preventing complications.A comprehensive treatment approach targeting multiple aspects of wound care may offer improved outcomes for patients with DFUs.The hypothesis of this study is that a comprehensive treatment protocol for DFUs will result in faster wound healing,reduced amputation rates,and improved overall patient outcomes compared to standard treatment protocols.AIM To compare the efficacy and safety of a comprehensive treatment protocol for DFUs with those of the standard treatment protocol.METHODS This retrospective study included 62 patients with DFUs,enrolled between January 2022 and January 2024,randomly assigned to the experimental(n=32)or control(n=30)group.The experimental group received a comprehensive treatment comprising blood circulation improvement,debridement,vacuum sealing drainage,recombinant human epidermal growth factor and anti-inflammatory dressing,and skin grafting.The control group received standard treatment,which included wound cleaning and dressing,antibiotics administration,and surgical debridement or amputation,if necessary.Time taken to reduce the white blood cell count,number of dressing changes,wound healing rate and time,and amputation rate were assessed.RESULTS The experimental group exhibited significantly better outcomes than those of the control group in terms of the wound healing rate,wound healing time,and amputation rate.Additionally,the comprehensive treatment protocol was safe and well tolerated by the patients.CONCLUSION Comprehensive treatment for DFUs is more effective than standard treatment,promoting granulation tissue growth,shortening hospitalization time,reducing pain and amputation rate,improving wound healing,and enhancing quality of life.

Professor Jun Li Treating Vascular Dementia from Mutual Conclusion of Phlegm and Blood Stasis

Professor Jun Li believes that the main etiology and pathogenesis of vascular dementia is the combination of phlegm and blood stasis.The symptoms include feeling faint and declined senses in organs of the head,caused by mystery reason.To cure phlegm and blood stasis simultaneously,the therapy promotes the notion of“resolving phlegm and stimulating the circulation of blood,liberate brain orifices,”and treatments with the addition and removal of“Naotaitong Decoction,”which has an amazing clinical curative effect.This paper examines Professor Jun Li’s theoretical foundations and ideas from the syndrome differentiation and treatment of phlegm and blood stasis,systematically examines the curative effect and mechanism of Naotaitong Decoction in the treatment of vascular dementia,and examines the prescription and medication of typical cases for readers,in the hopes of providing guidance to clinical diagnosis and treatment of this disease.
