OBJECTIVE: To summary and analyze the bleeding causes after uvulopalatopharyngoplasty(UPPP) with endotherm knife, and preventive measures will be given to effectively reduce postoperation hemorrhage. METHOD: Two hundred and twenty-six cases of obstructive sleep apnea hypopnea syndrome (OSAHS) adult patients, were carryed out UPPP under general anesthesia with endotherm knife to observe postoperation hemorrhage. RESULT: Eight cases out of 226 patients or 3.5% occurred postoperation hemorrhage, 2 cases after 1 or 2 days, 6 cases after 6 or 12 days. The postoperation hemorrhage stopped by local compression hemostasis or bi-polar coagulation hemostasis, and no more bleeding occurred. CONCLUSION The minimal trauma, quick operation and less-bleeding will be caused by UPPP with endotherm knife. Few patients 3.5% had a small amount of bleeding after operation, but no serious bleeding occured. Hemorrhage often happened during pseud mucosa falling off period. The bleeding was related with using skill of endotherm knife during operation, postoperation pse-ud mucosa falling off, local inflammation, improper eating and emotional stress of patients.

OBJECTIVETo explore the efficacy and the reproductive endocrinal mechanism of herbal-partitioned moxibustion in the treatment of primary dysmenorrhea.

METHODSOne hundred and seventy-one cases of primary dysmenorrhea were randomized into an herbal-partitioned moxibustion group (group A), an starch-partitioned moxibustion group (group B) and an acupuncture group (group C), 57 cases in each one. In the group A, moxibustion isolated with herbal medicine was applied to Shenque (CV 8). In the group B, moxibustion isolated with starch was used at Shenque (CV 8). In the group C, acupuncture was given at Sanyinjiao (SP 6). The changes of estradiol (E2), progesterone (P) and prostaglandin levels (PGF2alpha) were observed before and after treatment, and the therapeutic effects were compared among the 3 groups.

RESULTSThe therapeutic effect in the group A was better than those in the other two groups [compared the cured rate: 89.8% (44/49) vs 60.0% (30/50), 60.4% (32/53), both P < 0.05]. In the group A, E2 level [(110.99 +/- 12.90) pg/mL vs (83.94 +/- 8.91) pg/mL, P < 0.05] and PGF2alpha level [(24.58 +/- 3.01) pg/mL vs (14.34 +/- 1.48) pg/mL, P < 0.01] were decreased and P level was increased [(4.65 +/- 0.68) ng/mL vs (6.68 +/- 0.95) pg/mL, P < 0.05]. In the group B and C, PGF2alpha level were reduced. Concerning to the regulating of E2 and PGF2alpha levels, the results in the group A were better than those in the group B and C [(-30.16 +/- 10.20) pg/mL vs (10.79 +/- 15.01) pg/mL, (22.81 +/- 12.22) pg/mL; (-13.10 +/- 2.40) pg/mL vs (-6.52 +/- 1.88) pg/mL, (-3.14 +/- 1.19) pg/mL, (see text) P < 0.05]. Concerning to the regulation of P level, the results in the group A and B were better than that in the group C (all P < 0.05).

CONCLUSIONThe herbal-partitioned moxibustion achieves the significant efficacy on primary dysmenorrhea, which could be related to regulating the reproductive endocrinal level. It decreases E2 and PGF2alpha levels and increases P level.

Multiple sclerosis (MS) is an autoimmune disease. The etiology and pathogenesis of MS remain unclear. At present, there are substantial evidences to support the hypothesis that genetics plays a crucial role. The people who have genetic predisposing genes easily develop immune-mediated disorder, probably in conjunction with environmental factors. The aim of this review is to describe recent observations regarding the immunologic pathogenesis of MS.

Objective To evaluate the clinical value and effectiveness of ultrasound screening for fetal chromosomal abnormalitie in the middle and late pregnancy. Methods Fetuses who were detected with abnormal ultrasound findings during the middle and late pregnancy, and high risk of maternal serum screening underwent amnioeentesis or eordocentesis for fetal chromosome karyotypes. Results (1) A total of 31 cases with fetal malformation diagnosed by ultrasound were analysed for fetal chromosome karyotypes, and 8 (25.8%) cases were proved with fetal abnormal chromosome karyotypes. There were 3 cases of cervical springwater cyst accompany with edema,and all were fetal abnormal chromosome karyotypes. There were 3 cases of cervical pachyderma,and 2 were fetal abnormal chromosome karyotypes. There was one case with multiple malformations, one with Dandy-Walker malformation and one with holoprosencephaly malformation,all were revealed fetal abnormal chromosome karyotypes. (2) A total of 516 cases with high risk of Down's syndrome and trisomy 18 by maternal serum screening were analysed for fetal chromosome karyotypes,and 14(2.710%) cases were proved with fetal abnormal chromosome karyotypes, which include 7 cases of Down's syndrome and 7 cases of other fetal abnormal chromosome karyotypes. (3) A total of 544 (516 + 28)cases with high risk by the combination of ultrasound and maternal serum screening were analysed for fetal chromosome karyotypes, and 21 (3.86%) cases were proved with fetal abnormal chromosome karyotypes, the rate of detection higher than only maternal serum screening 42.43%.Conclusions Fetal structure abnormalities were the effective ultrasound signs for fetus chromosomal abnormalities screening in the middle and late pregnancy. The combination of ultrasound and maternal serum screening can improve the rate of fetus chromosomal abnormalities screening and be an effective way to retrieve false-positive and lower risk of maternal serum screening.

Background Eicosapentaenoic acid(EPA)function as the critical lipid mediators involved in several biological events in human body and play important role in suppressing the genesis of vascular endothelial growth factor (VEGF),migration and proliferation of vascular endothelial cells.Many ocular diseases were proved to be associated with neovascularization.Objecfive The purpose of this study was to investigate the inhibitory effect of EPA on the proliferation of human umbilical vein endothelial cells (HUVEC) indueed by VEGF. Methods HUVEC strain was cultured and passaged,and difierent concentrations of EPA were added to the medium with and without VEGF.The cultured cells were identified by antiofactor Ⅷ polyclonal antibody.The suppressing role of different concentrations of EPA on the proliferation of VEGF-induced or-uninduced HUVEC was assessed by MTT method.The influence of difierent concentrations of EPA on the cellular cycle of VEGF-induced HUVEC was assayed using flow eytometry.The expression of Flk-1,a receptor of VEGF,in the HUVEC Was detected by immunohistochemistry. Results Cultured HUVEC showed the ftlsiform in shape and presented with the cobblestone-like arrangement with the positive response for Ⅷ factor-related antigen.Various concentrations of EPA showed obviously inhibitory effect on VEGF-induced or-unindueed HUVEC at a dose-dependent manner (F=23.072.P=0.000).The inhibitory ability of EPA on VEGF-induced HUVEC was stronger than VEGF-uninduced HUVEC(F=41.417,P=0.000).In 24,48 and 72 hours,the action of EPA on the proliferation of HUVEC was gradually enhanced with the prolong of time(F=1.495,P=0.236).Cell cycle analysis indicated that EPA arrested VEGF-induced HUVEC in G0/G1 phase.The ratio of HUVEC in G0/G1 phase in EPA group was(75.83±1.56)%,and that in control groups was(68.62±1.44)%,showing a significant difference between them(t=-5.88,P=0.00),and no apoptosis of HUVEC was found in both groups.Flk-1 was strongly expressed in the cellular nucleus and cytoplasm in control group.However,the positive expressing intensity of Flk-1 in the HUVEC weakened,and the positive cell number was evidently less in EPA group. Conclusion EPA can inhibit the proliferation of VEGF induced HUVEC through arresting the synthesis of DNA of HUVEC and downregulate the expression of Flk-1 in HUVEC.These results suggest that EPA might exert an antiangiogenic effect.

OBJECTIVETo investigate the impact of adding folic acid, vitamin B(12) and probucol to standard antihypertensive medication on plasma homocysteine (Hcy) and asymmetric dimethylarginine (ADMA), serum NO and eNOS of essential hypertensive patients.

METHODA total of 120 patients with hypertension were randomly divided to three groups (n = 40 each): group 1 (standard medication), group 2 (adding folic acid 5 mg/day and vitamin B(12) 500 µg twice daily) and group 3 (adding folic acid 5 mg/day and vitamin B(12) 500 µg twice daily and probucol 500 mg twice daily). Plasma Hcy and ADMA, serum NO and eNOS levels were observed at baseline, 2 and 12 weeks after various therapy.

RESULTSIn group 1, concentrations of plasma Hcy [(23.06 ± 14.15) µmol/L, (23.67 ± 12.31) µmol/L, (23.25 ± 11.64) µmol/L], ADMA [(0.21 ± 0.12) µmol/L, (0.23 ± 0.13) µmol/L, (0.21 ± 0.09) µmol/L] and serum NO [(64.14 ± 15.07) µmol/L, (65.29 ± 15.04) µmol/L, (65.32 ± 13.58) µmol/L], eNOS [(20.02 ± 4.50) µg/L, (20.79 ± 4.03) µg/L, (19.82 ± 5.70) µg/L] remained unchanged during the 12 weeks therapy (all P > 0.05). In group 2, concentrations of plasma Hcy [(12.54 ± 6.49) µmol/L] and ADMA[(0.18 ± 0.07) µmol/L] were significantly decreased after the treatment of 12 weeks than the treatment baseline value [(21.51 ± 7.82) µmol/L, (0.20 ± 0.12) µmol/L] and 2 weeks value[(19.38 ± 8.14) µmol/L, (0.21 ± 0.12) µmol/L], however the concentrations of serum NO and eNOS showed contrary results of the Hcy and ADMA's. (all P < 0.05). In group 3, similar changes occurred at 2 weeks after therapy (P < 0.05 2 weeks vs. baseline and 12 weeks vs. 2 weeks). Plasma ADMA level was positively correlated with Hcy at baseline (r = 0.546, P < 0.05).

CONCLUSIONSSupplementation of folic acid, VitB(12) and/or probucol helps to improve endothelial function and reduce plasma Hcy and ADMA levels in patients with hypertension.

OBJECTIVETo investigate the advantages and disadvantages of dual energy with dual-source computed tomography (CT) in cerebral angiography by comparing those of neuro-digital subtraction angiography (Neuro-DSA) .

METHODSTotally 300 patients with normal CT angiography (CTA) images underwent dual energy CT angiography (DE-CTA groups, n=200) and Neuro-DSA scan (Neuro-DSA groups, n=100) using dual source CT. The comparison of two scan approaches was based on image quality, radiation does, post-processing methods, and duration of scanning and subtraction.

RESULTSThe image quality of intracranial blood vessels in DE-CTA group showed no significant difference with that in Neuro-DSA group (P>0.05) , while the number of Grade I images was significantly higher than those of other three grades (P<0.01) . However, the effect of the skull base bone removal with Neuro-DSA is superior to DE-CTA (P<0.01) . The duration of scanning was significantly longer in DE-CTA group than in Neuro-DSA group (P<0.01) . However, the radiation dose, time of entire examination, and time of subtraction were significantly lower/shorter in DE-CTA group than in Neuro-DSA group (P<0.01) . The radiation dose of DE-CTA group is 26.3% lower than Neuro-DSA group.

CONCLUSIONSThe image quality of intracranial blood vessels with head DE-CTA is same as Neuro-DSA, while head DE-CTA has lower radiation doses and higher inspection efficiency than Neuro-DSA. However, the effect of the skull base bone removal needs to be improved.
