ZHANG Wei-hua's clinical experience of Zhenjing Anshen method in treatment of insomnia / 中国针灸

The paper summarizes professor ZHANG Wei-hua's clinical experience in treatment of insomnia with Zhenjing Anshen (calming-down the spirit) method. It is believed that insomnia results from the unstable spirit in pathogenesis of TCM. The basic therapeutic principle is regulating the spirit, in which, stabilizing the primary spirit and tranquilizing the heart spirit are emphasized. Main acupoints are Baihui (GV 20), Sishencong (EX-HN 1) and Yintang (GV 24+) to stabilize the primary spirit, located on the head; and Shenmen (HT 7) located on the wrist to calm-down the heart spirit, as well as Sanyinjiao (SP 6) and Yongquan (KI 1) in the lower extremities to benefit yin and balance yang, and then to house the spirit eventually. The needles are inserted in different depths and to various directions. The external application of herbal plaster is combined at Yongquan (KI 1) and the supplementary acupoints are selected in terms of syndrome differentiation. This therapy is simple in acupoint selection and very effective in treatment of insomnia.

Post-stroke dysphagia treated with four-step acupuncture therapy for opening orifices and benefiting throat combined with neuromuscular electrical stimulation: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the clinical efficacy on post-stroke dysphagia treated with four-step acupuncture therapy for opening orifices and benefiting throat combined with neuromuscular electrical stimulation.@*METHODS@#Sixty patients with post-stroke dysphagia were randomly divided into an observation group and a control group, with 30 cases in each group. The neuromuscular electrical stimulation was adopted in the control group. Besides the treatment as the control group, in the observation group, the four-step acupuncture therapy for opening orifices and benefiting throat was supplemented. Step 1: the three areas of scalp acupuncture on the affected side were stimulated. Step 2: pricking method was operated on the posterior pharyngeal wall. Step 3: bleeding technique was operated at Jinjin (EX-HN 12) and Yuye (EX-HN 13). Step 4: deep insertion of needle was operated at three-pharynx points. The needles were retained for 30 min at the three areas of scalp acupuncture and the three-pharynx points. The intervention of each group was delivered once daily, 6 times a week, at the interval of 1 day. One course of treatment was 1 week and 4 successive courses were required. The rating of Kubota water swallow test, the score of standardized swallowing assessment (SSA) and the rating of Rosenbek penetration- aspiration scale (PAS) were observed before and after treatment in patients of the two groups. The incidence of clinical complications and clinical efficacy were compared between the two groups.@*RESULTS@#Compared with those before treatment, the rating of Kubota water swallow test, the scores of SSA and the rating of PAS of patients in the two groups were decreased after treatment (P<0.01), and the values of the observation group were lower than those of the control group after treatment (P<0.05). The incidence of clinical complications in the observation group was 13.3% (4/30), lower than 36.7% (11/30) in the control group (P<0.05). The total effective rate in the observation group was 93.3% (28/30), which was better than 70.0% (21/30) in the control group (P<0.05).@*CONCLUSION@#The four-step acupuncture therapy for opening orifices and benefiting throat combined with neuromuscular electrical stimulation can improve the swallowing function of patients with post-stroke dysphagia and reduce the incidence of clinical complications.

OBJECTIVE@#To investigate the cytokine/chemokine profile in patients with Epstein-Barr virus (EBV)-related hemophagocytic lymphohistiocytosis (HLH), and assess the prognostic value of survival.@*METHODS@#Serum levels of thirty-eight cytokines/chemokines were measured by multiple cytokine assay kit in EBV-related HLH patients, EBV-infected patients, and controls. The expression profile of cytokines/chemokines was compared among groups. The changes of cytokine/chemokine expression in active and remission stage of EBV-related HLH patients were also compared, and the prognostic values for survival were evaluated.@*RESULTS@#Serum levels of interferon-α2 (IFN-α2), interleukin (IL)-6, and IL-7 in EBV-related HLH patients were 33.67(23.23-68.78) pg/ml, (74.95±25.53) pg/ml, and 35.35(19.50-63.55) pg/ml, respectively, which were significantly higher than those in EBV-infected patients［IFN-α2: 16.07(9.87-29.63); IL-6: 55.91±20.29; IL-7: 20.40(13.35-31.40)］ and controls ［IFN-α2: 11.02(4.67-21.25); IL-6:42.64±13.41; IL-7: 16.95(14.95-33.78)］(all P<0.05). Serum levels of IL-8, IL-9, and marcophage-derived chemokine (MDC) in EBV-related HLH patients were 11.00(7.50-15.27) pg/ml, 81.30(40.79-111.0) pg/ml, and (512.6±128.7) pg/ml, respectively, which were significantly higher than those in controls ［IL-8: 6.80(5.56-8.38); IL-9: 41.30(29.82-67.91); MDC: 384.1±156.6］(all P<0.05), but there was no remarkable differences compared with EBV-infected patients (P>0.05). Serum IFN-α2, IL-6, IL-7, IL-8, IL-9, and MDC in survival and death groups of EBV-related HLH patients were analyzed by receiver operating characteristic curve with area under curve of 0.781, 0.778, 0.633, 0.805, 0.562, and 0.657, respectively (P=0.019, 0.021, 0.269, 0.015, 0.607, and 0.190). IFN-α2, IL-6, and IL-8 had good predictive effect on survival. Serum level of IFN-α2, IL-6, and MDC of EBV-related HLH patients in remission stage were significantly lower than those in active stage (P<0.05), while IL-7, IL-8, and IL-9 were not different (P>0.05).@*CONCLUSION@#IFN-α2, IL-6, IL-7, IL-8, IL-9, and MDC may take part in the pathogenesis of EBV-related HLH.

OBJECTIVE@#To explore method and clinical effect of microsurgical thinned anterolateral thigh perforator flap to repair soft tissue defects of foot and ankle.@*METHODS@#From March 2017 to January 2022, totally 20 patients with soft tissue defects of ankle joint were treated with micro-thinning anterolateral perforator flap for free transplantation, included 13 males and 7 females, aged from 22 to 58 years old with an average of (36.45±12.36) years old. The size of flap ranged from 8.0 cm×5.0 cm to 20.0 cm×12.0 cm. Before operation, perforating vessels on the anterolateral thigh region were detected and marked with a portable Doppler detector. For the defect width less than 8 cm, 11 patients were repaired with a single flap. For the defect width more than 8 cm, the wound could not be sutured directly, and the lobulated flap technique was used in 9 patients, the width was converted to length, and the donor site was closed directly. Under the microscope, all flaps were thinened in a stepwise manner from the center of the pedicle to the periphery. After operation, survival of the flap, the shape, texture, sensory function recovery were observes, and recovery of foot function was evaluated by Maryland foot function evaluation standard.@*RESULTS@#All 20 patients with microsurgical thinned anterolateral thigh perforator flaps were survived. Venous crisis occurred in 1 patient due to subcutaneous hematoma, after removal of the hematoma, the crisis was relieved and the flap survived successfully. The wounds in the donor and recipient sites healed well, and only linear scars left in the donor sites. Twenty patients were followed up for 3 to 26 months after operation, good shape of flaps without bloated, and good texture. The two-point discrimination of free flaps ranged from 9.0 to 16.0 mm, and the protective sensation was restored. The ankle flexion and extension function recovered well and patients could walk normally. According to Maryland foot function evaluation standard, 8 patients got excellent result, 10 patients good and 2 middle.@*CONCLUSION@#Microsurgical thinned anterolateral thigh perforator flap is an ideal method to repair soft tissue defects in functional area of foot and ankle, with good appearance and texture of the flap, no need for re-plastic surgery, reduced hospitalization costs, and less donor site damage.

Clinical analysis of long-term survival and influencing factors of chimeric antigen receptor T-cell therapy in relapsed/refractory acute B-cell lymphoblastic leukemia / 中华血液学杂志

Objective: To analyze the survival and influencing factors of chimeric antigen receptor (CAR) T-cell therapy in relapsed/refractory acute B-cell lymphoblastic leukemia (R/R B-ALL) . Methods: Clinical information of patients who received CAR-T-cell therapy and achieved complete remission of R/R B-ALL between May 2015 and June 2018 at the Shaanxi Provincial People's Hospital was obtained. Kaplan-Meier analysis was used to evaluate the overall survival (OS) and leukemia-free survival (LFS) times of patients, and Cox regression analysis was performed to analyze the prognostic factors that affect patient survival after CAR-T therapy. Results: Among the 38 patients with R/R B-ALL, 21 were men, with a median age of 25 (6-59) years and a median OS time of 18 (95% CI 3-33) months. Multivariate Cox regression analysis showed that positive MLL-AF4 fusion gene expression was an independent risk factor for OS and LFS (OS: HR=4.888, 95% CI 1.375-17.374, P=0.014; LFS: HR=6.683, 95% CI 1.815-24.608, P=0.004). Maintenance therapy was a protective factor for OS and LFS (OS: HR=0.153, 95% CI 0.054-0.432, P<0.001; LFS: HR=0.138, 95% CI 0.050-0.382, P<0.001). In patients with MRD negative conversion, LFS benefit (HR=0.209, 95% CI 0.055-0.797, P=0.022) and OS difference was statistically insignificant (P=0.111). Moreover, patients with high tumor burden were risk factors for OS and LFS at the level of 0.1 (OS: HR=2.662, 95% CI 0.987-7.184, P=0.053; LFS: HR=2.452, 95% CI 0.949-6.339, P=0.064) . Conclusion: High tumor burden and high-risk genetics may affect the long-term survival rate of patients with R/R B-ALL receiving CAR-T, and lenalidomide-based maintenance therapy may improve their prognosis.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Objective: To analyze the clinical features of patients with acute pulmonary embolism (APE) living in high altitude area of Yunnan province. Methods: This was a cross-sectional retrospective study. APE patients, hospitalized in our hospital between January 2017 and December 2019, were included. The selected patients were divided into low-risk group, medium-risk group and high-risk group according to risk stratification. The clinical data of patients, including demographic data, the main symptoms, risk factors of APE, heart rate and systolic blood pressure and laboratory testing results (D-dimer, cardiac troponin I (cTNI), N terminal B-type natriuretic peptide (NT-proBNP)) and echocardiography and electrocardiogram examination results, were obtained through the electronic medical record system. The clinical characteristics of selected patients were analyzed. Results: A total of 392 patients, aged (63.5±15.7) years, 224 males (57.14%), were included in this study and there were 59 low-risk, 304 medium-risk and 29 high-risk patients in this cohort. The main clinical manifestations were chest pain (157(40.05%)), dyspnea (107(27.30%)), hemoptysis (55(14.03%)), syncope as the first symptom (20(5.10%)), and only 6 cases (1.53%) presented with the typical "Virchow's triad". Most of the patients were accompanied by atypical chest tightness (223(56.89%)) and cough (208(53.06%)). The main risk factors were venous thrombosis of lower limbs (179(45.66%)), hypertension (138(35.20%)), surgery (63(16.07%)), and chronic obstructive pulmonary disease (COPD) (62(15.82%)). There were 57 cases (14.54%) of coronary heart disease, 57 cases (14.54%) of diabetes, 51 cases (13.01%) of cerebral infarction, 47 cases (12.00%) of advanced age, 15 cases (3.83%) of tumor, 7 cases (1.79%) of activity restriction, 6 cases (1.53%) of pregnancy and 4 cases (1.02%) of hormone use in this cohort. The proportion of lower extremity venous thrombosis was significantly higher in low-risk group than in medium-risk group (P<0.01), COPD was more common in high-risk and medium-risk groups than in low-risk group (P<0.01), hypertension was more common in high-risk group than in medium-and low-risk groups (P<0.01). The proportion of advanced age was significantly higher in medium-risk group than in low-risk group (P<0.01). There were no significant differences in RBC and hemoglobin level between low-, medium-and high-risk groups (P>0.05). The level of D-dimer was significantly higher in high-risk group than in medium-and low-risk groups (P<0.05). Levels of NT-proBNP and cTNI were significantly higher in high-risk group than in medium- and low-risk groups (P<0.05). Increased proportion of cTNI and NT-proBNP was significantly higher in high-risk group than in medium- and low-risk groups (P<0.05). There were 105 (26.79%) patients with pulmonary hypertension (PAH). The incidence of PAH was significantly higher in high-risk group than in low-risk group (P<0.01). There were 104 patients (26.53%) with right ventricular enlargement, and the incidence of right ventricular enlargement was significantly higher in high-risk group than in medium-and low-risk groups (P<0.01). Characteristic changes of electrocardiogram in patient with APE were T-wave inversion of limb leads (98(25.00%)), followed by SⅠQⅢTⅢ (83(21.17%)). Conclusions: The main clinical manifestations of APE in Yunnan high altitude area are chest pain and dyspnea, and syncope is the first symptom in some patients, but the typical "Virchow's triad" is rare. The most common risk factors are lower extremity venous thrombosis, hypertension, and COPD. Clinical symptoms, risk factors and laboratory examination results differ among patients with different risk stratification.

ZHANG Wei-hua's experience in clinical treatment of somatalgia with "point-zone-strip stimulation technique" of acupuncture / 中国针灸

The clinical experience in treatment of somatalgia with "point-zone-strip stimulation technique" of acupuncture of professor ZHANG Wei-hua was summarized. Professor ZHANG integrates the theories of the cutaneous region of meridian, biaoben, "taking tender point as acupoint" and local holography as a whole in treatment of somatalgia. The "point-stimulation technique" of acupuncture (subcutaneous needling technique) is adopted for the painful site less than 3 cm in diameter, the "zone-stimulation technique" (surrounding needling technique) is for the site larger than 3 cm in diameter and the "strip-stimulation technique" (cubit-tibia needling technique) is for various acute and chronic somatalgia. These three needling techniques are applicable singly or in combination in clinical practice.

Clinical effect of tacrolimus in the treatment of myasthenia gravis in children / 中国当代儿科杂志

OBJECTIVE@#To evaluate the efficacy and safety of tacrolimus in the treatment of children with myasthenia gravis (MG).@*METHODS@#A total of 28 children with MG were treated with tacrolimus. MG-Activities of Daily Living (MG-ADL) scale was used to assess clinical outcome and safety after 1, 3, 6, 9, and 12 months of treatment.@*RESULTS@#After tacrolimus treatment, the MG-ADL score at 1, 3, 6, 9 and 12 months was lower than that at baseline (P<0.05), and the MG-ADL score showed a gradually decreasing trend. The response rates to tacrolimus treatment at 1, 3, 6, 9, and 12 months were 59%, 81%, 84%, 88%, and 88% respectively. At 6, 9, 12, and 18 months of treatment, 4, 13, 14, and 15 children respectively were withdrawn from prednisone. No recurrence was observed during treatment. Major adverse reactions/events were asymptomatic reduction in blood magnesium in 5 children and positive urine occult blood in 1 child, which turned negative without special treatment, and tacrolimus was not stopped due to such adverse reactions/events. One child was withdrawn from tacrolimus due to recurrent vomiting. According to CYP3A5 genotypes, all of the patients were divided into two groups: slow metabolic type (n=19) and non-slow metabolic type (fast metabolic type + intermediate type; n=9). The non-slow metabolism group received a higher dose of tacrolimus, but had a lower trough concentration of tacrolimus than the slow metabolism group (P<0.05). The slow metabolism group had a higher response rates to tacrolimus treatment than the non-slow metabolism group (P<0.05).@*CONCLUSIONS@#Tacrolimus appears to be effective and safe in the treatment of children with MG and is thus an option for immunosuppressive therapy. CYP3A5 genotyping has a certain guiding significance for determining the dosage of tacrolimus.

Hereditary protein S deficiency: survey results from a Chinese pedigree / 中华心血管病杂志

Objective: To investigate the clinical characteristics and gene mutation, and analyze the association between genotype and phenotype of hereditary protein S deficiency in a Chinese pedigree. Methods: Hereditary protein S deficiency was diagnosed in January 2016 in our hospital. A total of 26 family members were surveyed in this study. Blood samples and clinical data were collected from them, and mutations were identified by Sanger sequencing. Pathogenicity of gene mutations was predicted by protein function prediction software including SIFT, PolyPhen_2, nsSNPAnalyzer and MutPred2. Swiss Model (https://swissmodel.expasy.org/) was used to perform homology modeling of the tertiary structure of the protein S wild-type and mutant-type, and observe the impact of gene mutation on the tertiary structure of the protein. Results: Four out of 26 family members of 4 generations were clinically diagnosed with hereditary protein S deficiency. The proband presented with recurrent pulmonary embolism and venous thromboembolism of the lower extremities, and her uncle and mother had a history of venous thromboembolism. Sequencing revealed a mutation in the c.200A>C gene in the second exon of the PROS1 gene of proband and part of her families (Ⅱ2, Ⅱ6, Ⅲ4, Ⅳ2). The prediction results of this gene mutation performed by SIFT, PolyPhen_2, nsSNPAnalyzer, MutPred2 were all harmful. The results of Swiss-Model homology modeling showed that the 67th amino acid was mutated from glutamic acid to alanine because of this gene mutation. Conclusion: A gene mutation cDNA (c. 200A>T) is identified in a Chinese pedigree with hereditary protein S deficiency. This gene mutation may reduce protein S activity, which may cause recurrent pulmonary embolism and venous thromboembolism of the patients.

Predictors related to condom use behaviors based on the theory of planned behavior among female sex workers / 中华疾病控制杂志

Objective To identify predictors related to condom use in different tiered female sex workers (FSWs) in Hubei Province. Methods A cross-sectional study was conducted in Hubei Province in 2015 to investigate 816 eligible FSWs by using a multistage sampling method. All data were collected by using a structured questionnaire with scales on condom use, which was designed based on the theory of planned behavior (TPB). A structural equation model (SEM) was used to identify predictors of condom use in the different tiered FSWs. Results It showed that low-tier FSWs used less condom than higher-tier FSWs in commercial sexual behaviors of the last time and during the last month(P<0.001). The TPB scores were significantly different in different tiered FSWs. The scores of PBC in low-tier FSWs were lower than those in higher-tier FSWs (11.43±2.86 vs 12.06±2.87, respectively, P=0.002); But the scores of behavioral intentions were higher than those in higher-tier FSWs (5.47±1.11 vs 5.20±1.15, respectively, P=0.001). The PBC was the major factor related to condom use in low-tier FSWs (effect coefficient=0.55, P<0.001), while the behavioral intention was the major factor related to condom use in higher-tier FSWs (effect coefficient=0.33, P<0.001). Behavioral attitude was the major factor of intention to use condoms for both low-tier (effect coefficient=0.49, P<0.001) and higher-tier FSWs (effect coefficient=0.42, P<0.001). Conclusions Changing the attitude to condom use in FSWs is an important measure to promote the behavior intention. Condom promotion interventions should focus on the perceived behavioral control in low-tier FSWs, and promote the behavior intention in higher-tier FSWs.

Objective To study the effect of operating rooms of two different cleanliness on surgical site infection (SSI)in neurosurgical craniocerebral operation,provide reference for the prevention and control of SSI.Methods Neurosurgical craniocerebral operation undertaking in grade I and II operating rooms in a hospital between July 2015 and July 2016 was performed retrospective study,patients in grade I operating rooms were as control group and those in grade II operating rooms were as trial group,occurrence of SSI was compared between two groups of pa-tients.Results A total of 454 patients undergoing craniocerebral operation were investigated,212 patients were in control group (grade I operating rooms)and 242 in trial group (grade II operating rooms).Patients in control group had 25 cases of SSI,incidence of SSI was 11.79%;trial group had 31 cases of SSI,incidence of SSI was 12.81%. Nine cases of SSI were superficial incision infection,there was no deep incision infection,the other 47 cases of SSI were intracranial infection(organ space infection).There was no significant difference in the incidence of SSI be-tween two groups of patients(P＞0.05).Conclusion Grade I and II cleanliness operating rooms have no direct effect on SSI in patients undergoing neurosurgical craniocerebral operation,comprehensive prevention and control mea-sures should be taken to prevent the occurrence of SSI.

Protective effects of Huanglian Wendan Decoction aganist cognitive deficits and neuronal damages in rats with diabetic encephalopathy by inhibiting the release of inflammatory cytokines and repairing insulin signaling pathway in hippocampus / 中国天然药物

Huanglian Wendan decoction (HLWDD) has been used for the treatment of symptom of "Re", one of major causes in diabetes and metabolic disorders, according to the theory of traditional Chinese medicine. The present study aimed at investigating the cerebral protective effects of HLWDD on diabetic encephalopathy (DE), one of the major diabetic complications. The effects of HLWDD and metformin were analyzed in the streptozocin (STZ) + high-glucose-fat (HGF) diet-induced DE rats by gastric intubation. In the present study, the effects of HLWDD on cognition deficits were investigated after 30-day intervention at two daily dose levels (3 and 6 g·kg). To explore the potential mechanisms underlying the effects of HLWDD, we detected the alterations of neuronal damages, inflammatory cytokines, and impaired insulin signaling pathway in hippocampus of the DE rats. Based on our results from the present study, we concluded that the protective effects of HLWDD against the cognitive deficits and neuronal damages through inhibiting the release of inflammatory cytokines and repairing insulin signaling pathway in hippocampus of the DE rats.

A Centralized Report on Pediatric Japanese Encephalitis Cases from Beijing Children's Hospital, 2013 / 生物医学与环境科学（英文）

Fifteen pediatric cases of suspected Japanese encephalitis (JE) were reported in Beijing Children's Hospital during the late summer of 2013. The clinical manifestations in most cases included high fever, seizures, and abnormal magnetic resonance imaging findings. Twelve of 15 cases were laboratory-confirmed as JE cases by pathogen identification. Epidemiological investigations showed that five of the 12 laboratory-confirmed patients had an incomplete JE vaccination history. Follow-up investigations after discharge indicated that seven laboratory-confirmed JE patients without JE vaccinations had relatively poor prognoses, with an average Modified Rankin Scale (MRS) score of 2.6 when compared with the other five laboratory-confirmed, JE-vaccinated patients with an average MRS score of 0.5. The observation of pediatric JE cases among those with a history of JE vaccination warrants further attention.

Mid-term outcome of endoscopic greater saphenous vein harvesting in coronary artery bypass grafting / 南方医科大学学报

<p><b>OBJECTIVE</b>To evaluate the mid-term clinical outcome of endoscopic greater saphenous vein harvesting (EVH) in coronary artery bypass grafting (CABG). Method A total of 205 patients receiving off-pump CABG between July, 2012 and April, 2013 at our department were enrolled in this study, including 66 patients (35 male and 31 female patients with a mean age of 60.3±7.92 years) undergoing EVH and 139 patients (109 male and 30 female patients with a mean age of 59.20±8.37 years) undergoing open greater saphenous vein harvesting (OVH).</p><p><b>RESULTS</b>The surgical procedures were completed smoothly in all the cases. The perioperative mortality rates was 3.03% (2/66) in EVH group, as compared with 3.60% (5/139) in OVH group (P=1.00). Acute myocardial infarction (AMI) occurred during the perioperative period in 3 (2.16%) patients in OVH group and in 1 (1.52%) patient in EVH group. Perioperative low cardiac output syndrome was diagnosed in 4 (2.88%) patients in OVH group and in 2 (3.03%) in EVH group (P>0.05). During the follow-up, 8 (8.80%) patients in OVH group and 5 (8.06%) in EVH group had recurrent angina (P=0.93). No patients experienced AMI during the follow-up. The 2-year patency rate of the venous grafts was 83.59% in OVH group and 82.22% in EVH group (P=0.73).</p><p><b>CONCLUSION</b>EVH has significant advantage in reducing the complications of the incision in the lower limbs. The mid-term patency rates of venous grafts are similar between OVH and EVH, but the long-term patency rate needs further evaluation.</p>
