ABSTRACT
ObjectiveTo study the effect and mechanism of Yixintai on mitochondrial fission proteins in the rat model of chronic heart failure. MethodTen of 60 SD rats were randomly selected as the sham operation group， and the remaining 50 rats were subjected to ligation of the left anterior descending coronary artery for the modeling of heart failure post myocardial infarction. The successfully modeled rats were randomized into model， low-， medium-， and high-dose （1.4， 2.8， and 5.6 g·kg-1， respectively） Yixintai， and trimetazidine （10 mg·kg-1） groups. The rats were administrated with corresponding doses of drugs by gavage， and the rats in the model group and sham operation group were given an equal volume of normal saline by gavage for 28 consecutive days. Enzyme-linked immunosorbent assay （ELISA） was then employed to measure the levels of amino-terminal pro-B-type natriuretic peptide （NT-pro BNP）， B-type natriuretic peptide （BNP）， and adenosine triphosphate （ATP） in the serum. Color Doppler ultrasound imaging was conducted to examine the cardiac function indicators. Hematoxylin-eosin staining and Masson staining were conducted to observe the pathological changes in the heart， and Image J was used to calculate collagen volume fraction （CVF）. Transmission electron microscopy was employed to observe the ultrastructural changes of myocardial cells. Terminal-deoxynucleoitidyl transferase-mediated nick-end labeling （TUNEL） was employed to measure the apoptosis rate of myocardial cells. Western blot was employed to determine the protein levels of mitochondrial fission protein 1 （Fis1） and mitochondrial fission factor （Mff） in the outer mitochondrial membrane of the myocardial tissue. ResultCompared with the sham operation group， the model group showed elevated levels of NT-pro BNP and BNP in the serum， decreased ATP content， left ventricular ejection fraction （LVEF）， and left ventricular fraction shortening （LVFS）， increased left ventricular end-diastolic diameter （LVIDd） and left ventricular end-systolic diameter （LVIDs）， disarrangement of myocardial cells， inflammatory cell infiltration， increased collagen fibers and CVF， damaged myocardium and mitochondria， and increased apoptosis rate of myocardial cells， and up-regulated expression of Fis1 and Mff in the cardiac tissue （P<0.01）. Compared with the model group， different doses of Yixintai and trimetazidine lowered the serum levels of NT-pro BNP and BNP （P<0.05）， increased the ATP content （P<0.05）， increased LVEF and LVFS （P<0.01）， decreased LVIDd and LVIDs （P<0.01）. Moreover， the drugs alleviated the myocardial inflammatory damage and fibrosis， reduced CVF （P<0.01）， repaired the myocardial mitochondrial structure， and decreased the apoptosis rate of myocardial cells （P<0.01）. Medium- and high-dose Yixintai and trimetazidine down-regulated the expression of Fis1 and Mff in the myocardial tissue （P<0.05）. ConclusionYixintai can improve mitochondrial structure， reduce myocardial cell apoptosis， and improve cardiac function by inhibiting the expression of Fis1 and Mff in the myocardial tissue.
ABSTRACT
Chronic heart failure(CHF)is a common and frequent clinical condition with complex pathogenesis.The micro-inflammatory state exists in the development of CHF and is manifested by a continuous increase in inflammatory proteins and inflammatory cytokines in the circulation,affecting the body's metabolism and immune function.Micro-inflammatory state of CHF belongs to the syndrome of deficiency in nature and excess in superficiality in the TCM field.The basic pathogenesis of CHF is"deficiency qi retention";the nature is the deficiency of heart energy and the superficiality is retention of qi,blood stagnation,phlegm,water and dampness,with"deficiency,stagnation and water"running throughout the disease.Therefore,based on the theory of"deficiency qi retention",this article took"reinforcing deficiency and removing stagnation"as its basic treatment method,regulated the body's immunity and inflammatory indicators such as serum high-sensitivity C-reactive protein,tumor necrosis factor-α,in order to alleviate the micro-inflammatory state,which is of great significance for the prevention and treatment of CHF.
ABSTRACT
Objective To investigate the biological basis of disease and syndrome by studying the spectrum of myocardial tissue metabolites in the rat model of coronary heart disease with heart blood stasis syndrome.Methods SD rats were randomly divided into sham-operation group and model group.The left anterior descending coronary artery was ligated to prepare the rat model of coronary heart disease with heart blood stasis syndrome.The general condition was observed,and the tongue chromaticity,electrocardiogram,cardiac function were detected.HE staining and transmission electron microscopy were used to observe myocardial tissue morphology and ultrastructure.UPLC-MS technology was used to investigate the differential metabolites in rat myocardial tissue,and enrichment analysis was conducted on metabolic pathways.Results Compared with the sham-operation group,the tongue chromaticity R,G,B values of model group rats were significantly reduced(P<0.05),ECG heart rate and ST segment elevation amplitude significantly increased(P<0.05),LVEF and LVFS significantly decreased,and LVIDs and LVIDd significantly increased(P<0.05).Myocardial tissue pathology revealed that the structure was blurred,inflammatory cells infiltrated,mitochondria swelled,ruptured,and dissolved,and crista structure fracture decreased.A total of 29 potential biomarkers with significant differences between the sham-operation group and the model group were identified in metabolomics(7 upregulated and 22 downregulated),with the majority of 10 pathways enriched in thiamine metabolism,arginine biosynthesis,purine metabolism,aminoacyl-tRNA biosynthesis,alanine,aspartate and glutamate metabolism,pentose and glucuronate interconversions,glycolysis/gluconeogenesis,valine,leucine and isoleucine degradation,TCA cycle,pyruvate metabolism.Conclusion Ligation of the left anterior descending coronary artery can mimic the pathological process of coronary heart disease with blood stasis syndrome in a good way,and its pathological mechanism involves the disruption of multi-level metabolic networks such as glucose metabolism,mitochondrial energy metabolism,amino acid metabolism,protein biosynthesis,and purine metabolism.
ABSTRACT
Heart failure is a group of complex clinical syndromes in the middle and late stages of cardiovascular diseases.Mitochondrial homeostasis imbalance is one of the pathological mechanisms in the occurrence and development of heart failure.This article revolved around the"yin-yang theory"in TCM and explained the pathological mechanism of heart failure through mitochondrial homeostasis.Heart failure is the syndrome of deficiency in nature and excess in superficiality fundamental.Its basic pathogenesis is"yang deficiency and yin excess".Based on the deficiency of heart yang qi and the stagnation of yin pathogens,the combination of deficiency and excess runs through the entire disease.Mitochondrial homeostasis imbalance is a manifestation of yin-yang imbalance at the cellular micro level,mainly manifested as inhibition of mitochondrial biosynthesis,mitochondrial dynamics imbalance,mitophagy disorder,etc.,which affects mitochondrial structure and function and leads to abnormal myocardial energy metabolism.Therefore,based on the"yin-yang theory",the basic treatment method is to"tonify deficiency and damage excess"to regulate mitochondrial biosynthesis,mitochondrial dynamics,and mitophagy,thereby maintaining mitochondrial homeostasis and improving myocardial energy metabolism,which is of great significance for the prevention and treatment of heart failure.
ABSTRACT
Heart failure is one of the main cardiovascular system diseases at present， and it is a clinical syndrome caused by changes in cardiac structure and function， resulting in impaired ejection function or ventricular filling. Therefore， heart failure has become the most important cardiovascular disease in the 21st century. In recent years， the incidence of heart failure is increasing， and the survival rate of patients with heart failure is very low. Traditional Chinese medicine has rich experience in preventing and treating heart failure. With the modernization of traditional Chinese medicine， more and more attention has been paid to the research， development， and application of active ingredients in traditional Chinese medicine. Traditional Chinese medicine has unique advantages in improving the heart function of patients with heart failure by treating multiple targets and multiple pathways through syndrome differentiation. Astragalus membranacus， a traditional Chinese medicine， is a kind of medicine that benefits Qi and blood circulation and removes evil spirits. It has the functions of improving myocardial energy metabolism and hemodynamics， protecting myocardial muscle， and promoting angiogenesis. Astragalus membranaceus is often used to treat patients with heart failure， yielding remarkable results. In recent years， it has been found that astragaloside， Astragalus polysaccharide， quercetin， calyx isoflavones， and other main active ingredients of Astragalus membranacus can improve cardiac function and treat heart failure by inhibiting inflammatory response， myocardial apoptosis， and myocardial fibrosis. This paper reviewed the research progress of the action and mechanism of the active ingredients of Astragalus membranacus in the treatment of heart failure by studying relevant literature， with a view to providing a reference for its further research， development， and application in the prevention and treatment of heart failure.

ABSTRACT
BackgroundThe course of schizophrenia is prolonged， and patients have impaired social function and significantly reduced quality of life. Drug therapy combined with psychological therapy is particularly important for improving the quality of life of patients. Brief cognitive behavioral therapy （BCBT） has been widely applied in clinical practice， but current research on BCBT focuses more on improving patients' symptoms and lacks relevant reports on improving quality of life. ObjectiveTo evaluate the efficacy and influencing factors of BCBT combined with conventional treatment on improving the quality of life in patients with schizophrenia. MethodsA total of 210 patients who met the diagnostic criteria for schizophrenia in the International Classification of Diseases （10th edition） （ICD-10） and were followed up at the outpatient department of Beijing Anding Hospital Capital Medical University from August 2011 to December 2016 were selected. Using a random number table method， patients were divided into study group and control group， with 105 cases in each group. Both groups received routine treatment， and the research group received a total of 8 BCBT sessions for 12 weeks on this basis. At the baseline period and 12 weeks of treatment， 26 weeks of follow-up and 52 weeks of follow-up， Positive and Negative Syndrome Scale （PANSS）， Personal and Social Performance Scale （PSP） and World Health Organization Quality of Life Brief （WHOQOL-BREF） were used for evaluation. ResultsThe results of repeated measures analysis of variance showed that the time point effect and interaction effect of PANSS total score were statistically significant （F=118.783， 8.083， P<0.01）.The time point effect， inter group effect and interaction effect of PSP total score were statistically significant （F=94.358， 4.048， 5.490， P<0.05 or 0.01）. The time point effect， inter group effect and interaction effect of the total score of WHOQOL-BREF were all statistically significant （F=12.330， 4.168， 4.142， P<0.05 or 0.01） Binary Logistic regression analysis showed that the study group （OR=1.861， 95% CI： 1.004~3.448） and young age （OR=1.044， 95% CI： 1.001~1.088） were protective factors for improving quality of life of patients， while high PANSS baseline score （OR=0.972， 95% CI： 0.945~0.999） was a risk factor for improving quality of life of patients. ConclusionThe combination of BCBT and conventional treatment has an earlier onset of improvement in the quality of life of patients with schizophrenia， and long-term efficacy is superior to conventional treatment.［Funded by Research Projects Supported by Beijing Municipal Commission of Science and Technology （number， Z111107058811078）； Capital Medical Development Fund Joint Research Project （number， 2009-1050）； Beijing Hygienism and Health Science and Technology Achievements and Appropriate Technology Promotion Project （number， TG-2017-38）； www.chictr.org.cn number： ChiCTR-TRC-13003709］
ABSTRACT
ObjectiveTo study the medication rules of Professor. WANG Xingkuan and inherit his academic experience in the treatment of chest stuffiness and pain with the aid of the Traditional Chinese Medicine Inheritance Computing Platform V3.0 （TCMICS V3.0）. MethodThe original medical records of patients with angina pectoris in coronary heart disease （CHD） diagnosed and treated by Prof. WANG in the outpatient department of Hunan University of Chinese Medicine from 2017 to 2020 were collected and entered into the TCMICS V3.0. The rules of prescriptions and drugs were analyzed by the software. ResultA total of 1 044 prescriptions of Prof. WANG for the treatment of chest stuffiness and pain were collected. Most of the drugs were sweet and bitter in flavor and mainly acted on the lung meridian， followed by heart， spleen， liver， stomach， and kidney meridians. Among the prescriptions， Shengmaisan was the most commonly used classic prescription， and Xintongling No. Ⅲ was the top experienced prescription. High-frequency drugs mainly included Ophiopogonis Radix， Pinelliae Rhizoma， Salviae Miltiorrhizae Radix et Rhizoma， Trichosanthis Pericarpium， Coptidis Rhizoma， Schisandrae Chinensis Fructus， and Bupleuri Radix. The common doses of drugs were 3， 5， 10， and 15 g. The analysis of formulation rules revealed 129 combinations of common drugs， 58 combinations with confidence > 0.99， and the core drugs of common syndromes. Six core drug combinations were obtained by drug clustering. ConclusionProfessor WANG treats chest stuffiness and pain based on syndrome differentiation following the principles of benefiting Qi， nourishing Yin， eliminating phlegm， resolving stasis， soothing liver， and promoting bile secretion， reflecting his academic idea of "regulation of multiple organs and comprehensive treatment". The core prescriptions can be used for reference by clinical practitioners， but further clinical and experimental studies are still needed to verify their efficacy.
ABSTRACT
In the case of cardiac dysfunction， energy metabolism changes and the metabolism of myocardial substrates is reconstructed， as manifested by variation in the selection and utilization of energy substrates such as fatty acids and glucose. Persistent metabolic disorders of substrates will decrease energy supply， thus resulting in the occurrence and development of heart failure. Metabolic remodeling of substrate is resulted from the decline of visceral function and the accumulation of pathological products. Deficient Qi stagnation is the core pathogenesis. Deficient Qi （heart Qi deficiency， insufficient energy） is the root cause， which exists in the whole disease course. Stagnation （phlegm， blood stasis， fluid， lipid toxic products， lactic acid， etc.） is the symptom， which evidences the aggravation of the disease. Deficient Qi and stagnation are intertwined and causal， which form a spiral vicious circle. The typical syndrome is excess resulted from deficiency and deficiency-excess in complexity. The treatment principle is reinforcing healthy Qi and tonifying deficiency， dredging and removing pathogen. At the early stage， the method of reinforcing healthy Qi and tonifying deficiency （benefiting Qi） should be used， and the method of dredging and removing pathogen （activating blood） can be applied according to the conditions of patients. At the middle and late stages， both reinforcing healthy Qi and tonifying deficiency （benefiting Qi and warming Yang） and dredging and removing pathogen （activating blood， resolving stasis， and excreting water） should be emphasized. Chinese medicine can be applied according to the pathogenesis， thereby promoting the utilization of fatty acids， glucose， and other substrates and reducing the accumulation of toxic products derived from metabolic remodeling of substrate. Thus， both the root cause and symptoms can be alleviated， further improving cardiac energy metabolism and heart function.

Results of univariate analysis showed that CEA, CA19-9, the number of polyps in preoperative ultrasonography examination, diameter of polyps in preoperative ultrasonography examination, polyp wall in preoperative ultrasonography examination were influence factors for the incidence of neoplastic polyps in patients who had gallbladder polyp diameter of 10 to 12 mm without cholecystolithiasis ( χ2=10.342, 5.616, 20.009, Z=-4.352, χ2=6.203, P<0.05). Results of multivariate analysis showed that CEA>5.0 mg/L, CA19-9>39.0 U/mL, single polyp in preoperative ultrasonography examination, polyp diameter of 11 mm in preoperative ultrasonography examination, polyps of broad base in preoperative ultrasonography examination were independent risk factors for the incidence of neoplastic polyps in patients who had gallbladder polyp diameter of 10 to 12 mm without cholecystolithiasis ( odds ratio=8.423, 0.082, 0.337, 3.694, 2.318, 95% confidence interval: 1.547-45.843, 0.015-0.443, 0.198-0.575, 1.987-6.866, 1.372-3.916, P<0.05). (6) Construction and evaluation of nomogram prediction model for neoplastic polyps of patients who had gallbladder polyp diameter of 10 to 12 mm without cholecystolithiasis: CEA, CA19-9, the number of polyps in preoperative ultrasonography examination, diameter of polyps in preoperative ultrasonography examination, polyp wall in preoperative ultrasonography examination were imported into R 3.6.0 version software to establish the nomogram prediction model for neoplastic polyps. The results showed the score for CEA>5.0 mg/L, CA19-9>39.0 U/mL, cases with single polyp in preoperative ultrasonography examination, cases with polyp diameter of 10 mm in preoperative ultrasonography examination, cases with polyp diameter of 11 mm in preoperative ultrasonography examination, cases with polyp diameter of 12 mm in preoperative ultrasonography examination, polyps of broad base in preoperative ultrasonography examination were 25, 27, 100, 0, 26, 72, 98 in the nomogram prediction model, respectively. The C-index of nomogram prediction model was 0.768. Result of nomogram prediction model showed that the incidence of tumor polyps was 0, 6% and 10% in patients with multiple and pedicled gallbladder polyps with diameter of 10, 11, 12 mm and with CEA ≤5.0 mg/L and CA19-9 ≤39.0 U/mL, the incidence of tumor polyps was 43%, 53% and 70% in patients with single and broad base gallbladder polyps with diameter of 10, 11, 12 mm. The calibration curve showed that the probability of the nomogram prediction model predicting neoplastic polyps was nearly consistent with the actual probability. Conclusions:CEA>5.0 mg/L, CA19-9>39.0 U/mL, single polyp in preoperative ultrasonography examination, polyp diameter of 11 mm in preoperative ultrasonography examination, polyps of broad base in preoperative ultrasonography examination are independent risk factors for the incidence of neoplastic polyps in patients who had gallbladder polyp diameter of 10 to 12 mm without cholecystolithiasis. Cholecystectomy should be performed in time for patients with single and broad based gallbladder polyps with diameter of 10, 11, 12 mm.
ABSTRACT
Objective@#To investigate the effect of hemoperfusion (HP) on the activity of ChE in blood of patients with organophosphorus poisoning, and its toxicant clearance effect.@*Methods@#From January 2017 to January 2019, 60 patients with organophosphorus poisoning in Shengjing Hospital Affiliated to China Medical University were divided into observation group and control group according to random number table method, with 30 cases in each group.The control group was treated with routine treatment, while the observation group was treated with HP on the basis of routine treatment.The therapeutic effects of the two groups were compared.@*Results@#The duration of mechanical ventilation and conscious awakening in the observation group were (3.07±1.14) d and (1.42±0.37) d, respectively, which were significantly shorter than those in the control group[(4.15±1.22) d, (2.01±0.58)d](t=3.543, 4.697, all P<0.05). The dosage of atropine in the observation group[(252.57±28.44)mg]was significantly less than that in the control group[(282.61±29.82)mg](t=3.993, P<0.05). The activity of cholinesterase after 12 h and 24 h of treatment was significantly higher than those before treatment (all P<0.05). After 12 h and 24 h of treatment, the cholinesterase activities in the observation group were (1 128.64±152.49)U/L and (1 422.08±184.68)U/L, respectively, which were higher than those in the control group[(912.73±144.61)U/L and (1 165.32±173.27)U/L](t=5.627, 5.553, all P<0.05). After 1 d and 3 d of treatment, the concentrations of organophosphorus poisons in the observation group were (1.08±0.30)mg/L and (0.62±0.18)mg/L, respectively, which were significantly lower than those in the control group[(1.32±0.35)mg/L and (0.84±0.27)mg/L](t=2.852, 3.713, all P<0.05). The incidences of rebound, intermediate syndrome and multiple organ failure in the observation group were 3.33% (1/30), 6.67% (2/30) and 13.33% (4/30), respectively, which were lower than those in the control group[23.33% (7/30), 23.33% (7/30), 36.67% (11/30)](χ2=5.192, 3.278, 4.356, all P<0.05).@*Conclusion@#HP has obvious effect on the activity of ChE and the concentration of blood poisons in patients with organophosphorus poisoning.It is worthy of popularizing and applying in clinic.
ABSTRACT
Objective@#To assess the outcomes of partial cricotracheal resection (CTR) and extended cricotracheal resection (ECTR) for severe laryngotracheal stenosis.@*Methods@#From November 2009 to September 2017, 18 patients underwent CTR and ECTR at the Department of Otorhinolaryngology Head and Neck Surgery, Tangdu Hospital, Air Force Medical University for severe laryngotracheal stenosis were reviewed retrospectively. There were 12-male and 6-female patients, with the age ranged from 4 to 56 years (median 25 years). The causes were postintubation in 11 cases, cervical trauma in 4, idiopathic in 3. The stenosis located in subglottic and tracheal (n=12), glottic and subglottic and tracheal (n=3), subglottic (n=2), and glottic and subglottic (n=1). Two patients had concurrent unilateral vocal cord palsy.One patient had undergone previous endoscopic balloon dilation and 8 patients had previous laryngotracheal reconstruction. The stenosis was graded according to modified Myer-Cotton classification as follows: Ⅲb (n=1), Ⅲc(n=1), Ⅳa (n=2), Ⅳb (n=12), Ⅳc (n=2). The surgical outcomes and complications were recorded.@*Results@#Among 18 patients,11 of the 12 patients undergoing CTR were decannulated. Five of the 6 patients undergoing ECTR were decannulated. Resected airway length ranged from 1.5 to 4.0 cm (median 2.8 cm). Surgical complications included infection of incision wound in 2 cases, anastomotic granulation in 2, cervical subcutaneous emphysema in 1, aspiration in 1, and unilateral arytenoid prolapse in 1. No recurrent laryngeal nerve injury or tracheoesophageal fistula occurred. The median follow up was 11 months.@*Conclusions@#CTR is efficient for severe subglottic and upper tracheal stenosis while ECTR is efficient for subglottic stenosis extended to the glottis. Both procedures also provide a salvage therapy for patients with previous failed treatments.

ABSTRACT
Objective@#The aim of this study is to o explore the diagnosis, treatment and prognosis of idiopathic subglottic stenosis （ISS） @*Method@#The clinical data of 15 patients with idiopathic subglottic stenosis treated in our department were analyzed retrospectively. The degree of stenosis was classified by the Cotton Airway grading system of Myer, with 8 cases of gradeⅡ, 4 cases of grade Ⅲ and 3 cases of grade Ⅳ. @*Result@#The time of follow-up of HTSS was 0.5-10 years. All 15 patients were successfully extubated without asphyxia, decannulation and wound nonunion. @*Conclusion@#For patients with idiopathic subglottic stenosis in the non-progressive stage, active surgical treatment strategy should be adopted and treated individually. The prognosis is satisfactory.
ABSTRACT
Objective@#To explore the application value of thyroid alar cartilage(TAC) in the laryngotracheal reconstruction of subglotticstenosis in the paediatric population.@*Methods@#Twelve patients(7 males,5 females; range from 2.3 to 12.0 years) with subglotticstenosis who had undergone laryngotracheal reconstruction procedures at our hospital fromSeptember 2016 to July 2018 were analyzed retrospectively.The degree of stenosis was classified according to Myer-Cotton classification system:grade Ⅱ(n=4),grade Ⅲ(n=6) and grade Ⅳ(n=2). The stenosis planes were subglotticbut did not exceed the 3rd tracheal cartilage ring.@*Results@#Of all 12 patients, 11 were decannulated and 1 failed. All patients with grade Ⅱ and Ⅲ patients were decannulated at one procedure. There were no severe complications such as tube dislogement,asphyxia and unhealed wound.@*Conclusions@#The TAC for widening laryngotracheal lumen is relatively simple and reliable for laryngotracheal reconstruction in the pediatric population with subglottic stenosis. This would′t cause any structural damage to the laryngeal cavity.
ABSTRACT
Objective:To analyze the sedative effect of dexmedetomidine in the elderly patients with intraspinal anesthesia .Meth-ods:Totally 52 elderly patients with intraspinal anesthesia were randomly divided into the observation group (26 cases) and the control group (26 cases).After anesthetized successfully , the patients in the control group were given normal saline with intravenous pum-ping,while those in the observation group were given dexmedetomidine with intravenous pumping .The levels of blood pressure , RR, SpO2and HR, the Ramsay sedation score and the adverse reactions of the two groups before anesthesia (T0),10 min after anesthesia (T1),30 min after anesthesia (T2),60 min after anesthesia (T3) and at the end of operation (T4) were compared.Results:The lev-els of RR, SpO2 and HR in the two groups were maintained within the normal range , while the levels of SBP ,HR at T2 and T3 were sig-nificantly lower than those at T 0 in the observation group , and also lower than those at the same time point in the control group ( P<0.05).The Ramsay sedation score from T2 toT4 were significantly lower than that at T0 in the observation group, and also lower than that at the same time point in the control group (P<0.05).The incidence of adverse reactions in the observation group was obviously lower than that in the control group .Conclusion: Dexmedetomidine used in the elderly patients with intraspinal anesthesia can keep hemodynamic stability and exhibits adequate sedation with significantly reduced adverse reactions , which is worthy of clinical promo-tion.
ABSTRACT
The self-compiled obsessive-compulsive cognitive behavioral therapy manual was used for a systematic and standardized cognitive behavioral therapy (CBT) intervention for a study of obsessive-compulsive disorder.Based on the assessment of consultant's compulsive thinking and compulsive behaviors,14 sessions of the systematic and standardized CBT treatments were conducted for maladaptive cognitive and behavioral problems.Yale-Brown Obsessive Compulsive Scale (Y-BOCS),Hamilton Depression Scale (HAMD-17) and Hamiltonian anxiety (HAMA) were used to evaluate the change of the mood and symptoms before and after the cognitive and behavioral therapy.The symptoms of consultant were alleviated effectively and the overall function was significantly improved after 14 CBT treatments.The treatment reached the desired treatment goals.This study suggests that self-compiled cognitive behavior therapy manual is effective for the obsessive-compulsive disorder in practice and it has a guiding significance on the normative treatment of obsessive-compulsive disorder.
