Objective To ob serve the clinical effect of blood-activating and stasis-dissolving drugs combined with western medicine ( WM) for the treatment of recurrent spontaneous abortion ( RSA) induced by prethrombotic state ( PTS). Methods A total of 120 patients with RSA at PTS were randomly assigned to treatment group (68 cases) and control group (52 cases). Patients in both groups were treated with aspirin and low molecular weight heparin, while those in the treatment group additionally received Chinese medicine for activating blood and dissolving stasis. Before and after treatment, indexes of coagulation-fibrinolysis and the development of embryos were compared between the two groups. Results The therapeutic effective rate was 88.24% in the treatment group, higher than that of the control group ( 69.23%, P<0.05). The levels of plasma thrombin time ( TT) , D-dimer, fibrinogen and antithrombin Ⅲ ( AT-Ⅲ) were all improved ( P<0.05) in the two groups after treatment. Besides, the treatment group had better effect on improving levels of plasma D-dimer, fibrinogen and AT-Ⅲ ( P<0.05). During the treatment, no drug-induced adverse reaction was found. Neither neonatal deformity nor maldevelopment occurred. Ninety-seven cases achieved successful pregnancy, and 45 cases had given term girth ( 29 cases from the treatment group and 16 from the control group). Fifty-two cases were in stable middle- and late-stage of pregnancy. Conclusion Therapy of activating blood and dissolving stasis is an effective method for RSA at PTS. It has obvious effects on improving high coagulation state during pregnancy. Chinese medicine combined with WM shows better therapeutic efficacy than WM alone.

Objective To investigate the effect of fire needling on tumor marker CA-125 levels and endometrial antibody (EMAb) in endometriosis patients.Methods Eighty endometriosis patients were randomly allocated to a treatment group of 43 cases and a control group of 37 cases. The treatment group received fire needling and the control group took gestrinone capsules. CA-125 levels and EMAb were measured in the two groups before and after treatment.Results CA-125 levels and EMAb positive rate decreased significantly in the two groups after treatment compared with before (P<0.05) but there were no statistically significant post-treatment differences between the two groups (P>0.05).Conclusion Fire needling has a good interference effect on CA-125 levels and EMAb in endometriosis patients.

Objective To measure and determine the position of the tibial attachment of the anterior cruciate ligament (ACL)in relation to its anterior ridge on the magnetic resonance imaging (MRI)of normal knee joints,and to explore the clinical role of the anterior ridge in guiding tunnel positioning during ACL reconstruction as well as in facilitating postoperative radiographic evaluation.Methods The knee MRI of one hundred young adult patients with an intact ACL and normal knee joint (mean age:25.1 years,range:18-40 years)was retrospectively reviewed.All MR images were obtained at full extension of the knee on the same MRI machine.Using digital image software on MRI,the measurements in the sagittal view were taken,including the depth of the tibia,the distance from the anterior edge of the tibial plateau to the most anterior and posterior portions of the ACL insertion on the tibia and the anterior ridge according to Staubli and Rauschning's method.Results The center of the tibial insertion of the ACL is located between 28.43％ and 50.94％ of the total anterior-posterior depth of the tibia,which was less than 43.3％ in 58 patients.The average distance from the anterior edge of the tibial plateau to the anterior ridge was 13.61 ± 2.17 mm (ranging from 8.03 to 18.65 mm),26.80％ ±3.89％ (ranging from 17.74％ to 33.94％)across the tibial plateau.There were significant positive correlations between the distance from the anterior edge of the tibial plateau to the most anterior portion of the ACL insertion and that to the anterior ridge.The distance from the most anterior portion of the ACL insertion to the anterior ridge was averaged 0.56 ± 0.68 mm (ranging from-0.28 to 2.71 mm).During the ACL reconstruction,with the anterior edge of the tibial tunnel determined at posterior 0.5 mm to the anterior ridge,the graft size as 8 mm,and the tibial guider angle set as 55 degree,96of the patients (96％)would have the center of the tibial tunnel located before the center of their native ACL attachment.Conclusions On sagittal MR images,the location of the anterior ridge and the most anterior portion of the ACL insertion correlated well,with the average distance between them of 0.56 mm.The study indicates that during ACL reconstruction,tibial tunnel drilling with the anterior edge of the ACL graft positioned at the anterior ridge can achieve a more anterior position than the traditional methods to orientate according to the center of the bone tunnel.

Objective To investigate the clinical efficacy of fire needling in treating endometriosis.Method Fifty-eight endometriosis patients were randomly allocated to treatment and control groups. The treatment group received fire needling at specific points. The treatment was given at one week before menstruation until the end of it, twice a week, three months as a course. The control group took gestrinone 2.5 mg from the first day of menstruation, twice a week, for three consecutive months. The therapeutic effects were evaluated in both groups at three months after the end of treatment.Result The cure rate and the efficacy rate were significantly higher in the treatment group than in the control group (P＜0.05). The pregnancy rate was also higher in the treatment group than in the control group (P＜0.05).Conclusion Fire needling treatment for endometriosis has the advantages of good therapeutic effect, high cure rate and no influence on pregnancy.

Objective: To observe the effects of ginger-partitioned moxibustion at Shenque (CV8) and Guanyuan (CV4) on the expression levels of endocrine-related molecules and their receptors in rats with primary dysmenorrhea (PD) due to cold-dampness stagnation, thus to explore their analgesic mechanisms. Methods: Thirty-two female Wistar rats were divided into a normal group, a model group, a ginger-partitioned moxibustion group, and a Western medicine group according to the random number table method, with 8 rats in each group. Except for rats in the normal group, all other rats were treated with oxytocin combined with ice-water bath to establish the rat models of PD due to cold-dampness stagnation. After successful modeling, rats in the normal group and the model group did not receive treatment; rats in the ginger-partitioned moxibustion group received treatments with ginger-partitioned moxibustion at Shenque (CV8) and Guanyuan (CV4); rats in the Western medicine group received ibuprofen by intragastric administration. The writhing response of rats was compared among groups, and the serum levels of prostaglandin F2α (PGF2α), estrogen (estradiol, E2), progesterone (P), and the mRNA expression of PGF2α and E2 receptors in the uterine tissues were detected. Results: No writhing behavior was observed in the normal group; compared with the normal group, the serum PGF2α and E2 levels in the model group were increased (P<0.01), while the P level was decreased (P<0.01), and the mRNA expression levels of the uterine PGF2α and E2 receptors were increased (P<0.01, P<0.05). Compared with the model group, the writhing behavior latency was prolonged, and the writhing response score was decreased in the ginger-partitioned moxibustion group and the Western medicine group (P<0.01); the serum PGF2α and E2 levels in the ginger-partitioned moxibustion group and the Western medicine group were decreased, while the P level was increased (P<0.05 or P<0.01); the mRNA expression levels of the uterine PGF2α and E2 receptors in the ginger-partitioned moxibustion group and the Western medicine group were decreased (P<0.05). Compared with the Western medicine group, the ginger-partitioned moxibustion group showed a prolonged writhing behavior latency, reduced writhing response score (P<0.05), and decreased serum E2 level (P<0.05), while no statistical differences in the serum PGF2α and P levels, or the mRNA expression levels of uterine PGF2α and E2 receptors (P>0.05).Conclusion: The analgesic effect of ginger-partitioned moxibustion on PD due to cold-dampness stagnation may be related to regulating the mRNA expression levels of PGF2α and E2 receptors in the uterine tissues.

Objective To compare the sedative and analgesic effects of remifentanil combined with propofol administered by target-controlled infusion(TCI)and intravenous infusion during local anesthesia.Methods Sixty ASA Ⅰ or Ⅱ patients,aged 18-55 yr,with body mass index ＜ 30 kg/m2,scheduled for plastic surgery under local anesthesia,were equally and randomly divided into TCI group(group T)and intravenous infusion group (group V).Remifentanil(the initial target plasma concentration 1.0 ng/ml)and propofol(the initial target plasma concentration 1.0 ng/ml)were given by TCI before local anesthesia in group T.Remifentanil was infused at a rate of 0.05 μg·kg-1 ·min-1 after a loading dose of 0.25 μg/kg and propofol was infused at a rate of 3 mg·kg-1 ·h-1 after a loading dose of 0.5 mg/kg in group V.The target plasma concentration or infusion rate was adjusted to maintain the modified OAA/S score of 2 or 3.Hypoxemia,bradypnea and/or apnea were recorded during operation.The total amount of remifentanil and propofol consumed was calculated.Results Compared with group V,the incidence of hypoxemia,bradypnea and/or apnea were significantly decreased during operation,and the total amount of remifentanil and propofol consumed was significantly reduced in group T(P ＜ 0.05).Conclusion The sedative and analgesic effects of remifentanil combined with propofol given by TCI are superior to those given by intravenous infusion during local anesthesia,with better safety.

Objective To explore the value of contrast-enhanced ultrasound(CEUS) in the evaluation of the renal cortical perfusion in rabbits in low temperature conditions.Methods 20 New Zealand rabbits were randomly divided into five groups,4 rabbits in each group:1) with the first group as the control group (under the conditions of room temperature) ; 2)The second group was treated under-15℃--23℃ for 8hours; 3)the third group was treated under-15℃--23℃ for 4 hours; 4)the fourth group was treated under-6℃--14℃ for 8 hours; 5) the fifth group was treated under-6℃--14℃ for 4 hours.SonoVue was injected via the ear vein at a dose of 0.1 ml/kg,the renal perfusion imaging was made,observing the dynamic image of 0-3 min after the injection and analyzing the time-intensity curves(TIC)obtained from the following parameters:the slope rate of ascending curve(A),the slope rate of descending curve(α),area under the curve (AUC),time to peak (TTP),and derived peak intensity(DPI).Results Compared with the control group,the A,α of the second and the fourth group were significantly decreased (P ＜ 0.05),while the AUC was significantly increased (P ＜ 0.05) and the TTP was significantly prolonged(P ＜0.05),for the third and the fifth group,only the A was decreased (P ＜0.05),and the DPI in each group showed no significant difference.Compared with the third and the fourth group,the AUC of the second group was increased and the TTP was prolonged (P ＜0.05).Conclusions Contrast-enhanced ultrasound can reflect the earlier renal cortical hemodynamic changes in rabbits in the low-temperature conditions,and is of great value for the early diagnosis of renal damage caused by low temperature.

Objective To understand the effect of anti-cysticercus therapy for patients with cerebral cysticercosis and the changes of cysticercus on CT image after treatment. Methods The patients with cerebral cysticercosis were classified by the presentation of their brain CT image before treatment, then the effect of anti-cysticercus therapy on them after treatment was analyzed and the presentations of their brain CT images between before and after treatment were compared. Results There were different changes on CT image of cysticercus in brain tissues after anti-cysticercus therapy for different types of patients with cerebral cysticercosis. Type Ⅰ: the focus was absorbed completely after treatment in the majority of patients and calcificated in the minority. Almost all the patients were cured clinically after anticysticercus therapy. Type Ⅱ: the focus was absorbed completely in the minority, and one to two or more calcification dots were observed in the majority of patients. Anti-cysticercus therapy was effective. Type Ⅲ and Ⅳ: the absorption of focus was not very good and the effect of anti-cysticercus therapy was lower relatively. Conclusion The changes of CT image such as absorption, calcification, has important significance in forecasting prognosis and instructing clinical usage.
