OBJECTIVETo investigate the effect of Shengmai Injection (SMI) on blood coagulation in patients with chronic heart failure (CHF).

METHODSSixty patients with CHF were randomly divided into two groups, the 30 patients in the treated group were treated with SMI plus conventional treatment of western medicine, and the 30 in the control group treated with conventional treatment alone. The changes of cardiac function were observed and levels of plasma P-selectin, von Willebrand's factor (vWF) and D-dimer were determined.

RESULTSThe total effective rate and the markedly effective rate in the treated group were higher than those in the control group respectively. The levels of P-selectin, vWF and D-dimer lowered in both groups significantly after treatment, but the effect of lowering was better in the treated group than that in the control group.

CONCLUSIONHypercoagulative state exist in patients with chronic heart failure. SMI could improve the state in patients, which may reduce the occurrence and developing of emboic events to certain extent.

AIMTo study the cutaneous permeation kinetics and pharmacodynamics of lidocaine gel.

METHODSThe concentration of lidocaine in dermis following topical application in rats was determined by the cutaneous microdialysis technique and related parameters were calculated; the pharmacodynamics of the gel was evaluated by electric stimulation method with EMLA (eutectic mixture of local anesthetics) cream as a control.

RESULTSThe peak of percutaneous absorption kinetic profile of lidocaine gel across rat skin occurred at 1.25 h; the onset time of local anesthetic action of lidociane gel was similar to that of EMLA, but both the duration and depth of anesthetic effect were superior to EMLA cream.

CONCLUSIONLidocaine gel showed good anesthetic effect. The minimum effective concentration of lidocaine in dermis is 12 mg.L-1.

OBJECTIVETo discuss the best surgical approach to the skull base neoplasms.

METHODSRetrospective analysis the 79 skull base neoplasms cases treated with surgical resection in Qilu hospital of Shandong university from 1992 to 2002. Eleven surgical approaches including midfacial degloving, frontal coronal discission, nasal eversion, maxillary swing, partial maxillary resection, total resection of orbit, mandibular swing, combination of front, temple, preauricular, post aureum, neck, and transoral approaches were used to resect the tumor which involved fossae pterygopalatine, paranasal sinuses, nasopharynx, antero, meso and posterobasilar region, lobi frontalis and lobi temporalis of cerebrum.

RESULTSSeventy-nine skull base neoplasms were totally removed and no one died from the operation. Although 5 cases complicated with cerebrospinal fluid leak and all recovered within 1 week, no serious cranium-cerebrum complication occurred. In 29 patients with benign tumor including 11 cases of meningioma, 3 cases of chondroma, 1 case of hemangio-meningioma, 1 case of cavernous hemangioma, 2 cases of osteodysplasia fibromas, 9 cases of neurofibroma, 1 case of glomus jugular tumor, 1 case of neurilemmoma, 19 have survived over 5 years and the longest one has survived over 8 years. For 50 patients with malignant tumor including 3 cases of well-differentiated squamous cell carcinoma, 17 cases of moderately differentiated squamous cell carcinoma, 11 cases of poorly differentiated squamous cell carcinoma, 1 case of undifferentiated carcinoma, 2 cases of chondrosarcoma, 5 cases of canceration of papilloma, 2 cases of adenocarcinoma, 1 case of esthesioneuroblastoma, 2 cases of malignant fibrohistiocytoma, 1 case of fibrosarcoma, 2 cases of malignant mixed tumour, 3 cases of sarcoma survival rates of 3 and 5 years were 59.2% (29/49), 38.5% (10/26) respectively.

CONCLUSIONIn order to resect the tumor completely and reduce the complication and malformation as far as possible, different surgical approaches must be designed according to the pathological changes characters and involved area,and the surgeon should select the shortest approach, avoid to damage the important neurovascular structure, and resect the tumor through the natural anatomy space by the shelter incision.

OBJECTIVETo improve the surgery results and living quality of patients following the operation of the combined approach of tympanoplasty and mastoidectomy with close technique.

METHODSThe clinical data and following-up results of 49 patients treated with combined approach of tympanoplasty and mastoidectomy with close technique and 82 patients treated with open mastoidectomy with tympanoplasty were retrospective analyzed.

RESULTSIn the group treated with combined approach tympanoplasty, all patients got dry ear in 20 days and 31 patients' hearing level enhanced over 15 dB after the operation; but in the group treated with open mastoidectomy with tympanoplasty, only 13 patients got dry ear in 20 days and no patients' hearing level enhance over 15 dB after the operation. Although the recurrence rates between two groups were not significant difference, the patients of former group not only took a shorter recovery time and got a better hearing recovery, but also kept a normal external auditory meatus, at the same time, they need not to clear scab at fixed period all life long.

CONCLUSIONSWhen performed on carefully selected patients, combined approach tympanoplasty was a feasible surgical method to improve the surgery results and living quality of patients following the operation, however, the advanced equipment and perfect operation skill are necessary.

OBJECTIVES: To explore a new method for electroencephalography (EEG) background analysis in neonates with hypoxic-ischemic encephalopathy (HIE) and its relationship with clinical grading and head magnetic resonance imaging (MRI) grading. METHODS: A retrospective analysis was performed for the video electroencephalography (vEEG) and amplitude-integrated electroencephalography (aEEG) monitoring data within 24 hours after birth of neonates diagnosed with HIE from January 2016 to August 2022. All items of EEG background analysis were enrolled into an assessment system and were scored according to severity to obtain the total EEG score. The correlations of total EEG score with total MRI score and total Sarnat score (TSS, used to evaluate clinical gradings) were analyzed by Spearman correlation analysis. The total EEG score was compared among the neonates with different clinical gradings and among the neonates with different head MRI gradings. The receiver operating characteristic (ROC) curve and the area under thecurve (AUC) were used to evaluate the value of total EEG score in diagnosing moderate/severe head MRI abnormalities and clinical moderate/severe HIE, which was then compared with the aEEG grading method. RESULTS: A total of 50 neonates with HIE were included. The total EEG score was positively correlated with the total head MRI score and TSS (r_s=0.840 and 0.611 respectively, P<0.001). There were significant differences in the total EEG score between different clinical grading groups and different head MRI grading groups (P<0.05). The total EEG score and the aEEG grading method had an AUC of 0.936 and 0.617 respectively in judging moderate/severe head MRI abnormalities (P<0.01) and an AUC of 0.887 and 0.796 respectively in judging clinical moderate/severe HIE (P>0.05). The total EEG scores of ≤6 points, 7-13 points, and ≥14 points were defined as mild, moderate, and severe EEG abnormalities respectively, which had the best consistency with clinical grading and head MRI grading (P<0.05). CONCLUSIONS The new EEG background scoring method can quantitatively reflect the severity of brain injury and can be used for the judgment of brain function in neonates with HIE.

Objective: To determine the prevalence and determinants of folic acid (FA) supplementation in Chinese couples planning for pregnancy and in women during early pregnancy. Methods: This was a cross-sectional study based on the Shanghai PreConception Cohort (SPCC) study. Data on FA supplementation and socio-demographic features were collected using questionnaires. Couples visiting clinics for pre-pregnancy examination and pregnant women at < 14 gestational weeks were recruited in Shanghai, China, between March 2016 and September 2018. Results: Among the pregnancy planners, 42.4% (4,710/11,099) women and 17.1% (1,377/8,045) men used FA supplements, while 93.4% (14,585/15,615) of the pregnant women used FA supplements. FA supplement use was higher in female pregnancy planners who were older ( : 1.13, 95% : 1.08-1.18), had higher education ( : 1.71, 95% : 1.53-1.92), and were residing in urban districts ( : 1.06, 95% : 1.01-1.11) of FA supplementation; female pregnancy planners with alcohol consumption ( : 0.95, 95% : 0.90-0.99) had lower odds of FA supplementation. In early pregnancy, women with higher educational level ( : 1.04, 95% : 1.03-1.06), who underwent pre-pregnancy examination ( : 1.02, 95% : 1.01-1.03) had higher odds of using an FA supplement; older aged ( : 0.99, 95% : 0.98-0.99), and multigravida ( : 0.97, 95% : 0.96-0.98) had lower odds of FA supplementation. Conclusion Although the majority of pregnant women took FA supplements, more than half of the women planning for pregnancy did not. Urgent strategies are needed to improve pre-conception FA supplementation.
