0.05). The pathological findings indicated benign lesions in 63 patients(73%) and malignant lesions in 25 patients(27%)in group 1. All the lesions were found benign in group 2. There was significant difference between the two groups(P=0.0033). Conclusion Noninvasive and painless transvaginal two-dimensional ultrasonograpy and color Doppler ultrasonography may have important clinical application value in diagnosis of intrauterine anomaly in post-menopausal women.

Aim To investigate the effects of Shaoqiduogan(SQDG)on cellular immunity in mice with delayed-type hypersensitivity(DTH). Methods DTH model induced by 2, 4-dinitrochlorobenzene(DNCB)and cyclophosphamide(Cy)suppressed and potentiated DTH model were used. SQDG(30, 60 and 120 mg ? kg-1)were given intragastrically(ig)once daily for 7 consecutive days. Concanavalin A(Con A)-induced T cells proliferation was measured by MTT assay. The activity of IL-2 in culture supernatants of Con A-induced T cells proliferation was measured by testing its ability to support the proliferation of Con A stimulated thymocytes which was detected by MTT assay. Results In mice with DTH, SQDG(120 mg?kg-1)reduced ear swelling, thymus index, Con A-induced T cells proliferation and the activity of IL-2 in culture supernatants of Con A-induced T cells proliferation. The suppression and potentiation of DTH in mice were induced by given an intraperitoneal(ip)injection of Cy at the dose of 150mg?kg-1 on primary sensitization day and 250 mg?kg-1 three days before primary sensitization. SQDG(60 and 120 mg?kg-1)upregulated ear swelling, Con A-induced T cells proliferation and the activity of IL-2 in culture supernatants of T cells from mice with Cy-suppressed DTH; and downregulated levels of the aforementioned indexes in mice with Cy-potentiated DTH. Conclusion SQDG possesses a dual modulatory effect on cellular immunity in mice.

Lactate and succinate were produced by Corynebacterium acetoacidophilum from glucose under oxygen deprivation conditions. To construct knockout mutant, lactate dehydrogenase gene (ldh) of C. acetoacidophilum was deleted by double-crossover chromosome replacement with sacB gene. Comparing with the wild strain ATCC13870, ldhA-deficent mutant produced no lactate with glucose consumption rate decreased by 29.3%, while succinate and acetate concentrations were increased by 45.6% and 182%, respectively. Moreover, the NADH/NAD+ rate was less than 1 (about 0.7), and the activities of phosphoenolpyruvate carboxylase and acetate kinase of the ldhA-deficent mutant were enhanced by 84% and 12 times, respectively. Our studies show that succinicate and acetate production pathways are strengthened by blocking lactate synthesis. It also suggests that improving NADH supply and eliminating acetate generation are alternative strategies to get high succinate-producer.

Objective To study the related factors of recurrence after myomectomy. Methods The clinical data of 441 cases with myomectomy were collected. The age at the time of operation, body mass index(BMI), preoperative parity, and the location, size and number of myomas were recorded, and the postoperative recurrence rate was calculated. Univariate and multivariate analysis were performed for possible factors related to recurrence. Results The average time of follow-up was(37.79?18.64) months. Recurrence was found in 125 cases, and 5-year cumulative rate of recurrence was 38.9%. The age at the time of operation, BMI, number of myomas and preoperative parity were related factors of recurrence(P

The stability of the intraocular lens ( IOL ) after cataract surgery is composed of decentration, tilt, rotation, and the change of anterior chamber depth. Its stability is an important factor affecting postoperative visual quality. By analyzing the related factors which influence the stability of intraocular lens, improvements can be identified for future cataract operations. The stability of intraocular lens is influenced by many factors: intraocular structure, the size and the symmetry of intraoperative capsulorhexis, the position of the intraocular lens, the material and design of the intraocular lens, etc. In order to improve the patient's vision, cataract surgeries have been experiencing an evolution. IOL material have also been contributing to such innovations.

MIC.RESULTS The bacteriostatic/bactericidal CFR of 0.5g q8h imipenem/cilastatin and 0.5g q8h meropenem were the highest(100%);that of 3.375g q4h sodium piperacillin/tazobactam sodium against ESBLs-producing E.coli was above 90%;the CFRs of ceftriaxone(1g q24h,2g q24h),ceftazidime(1g q8h,2g q8h),cefepime(1g q8h,1g q12h,2g q8h) and cefoperazone sodium/sulbactam(0.5g q8h,1g q8h,2g q8h) against ESBLs-producing strains were clearly less than those of non-ESBLs-producing ones,and the CFRs could not be effectively improved with the dose and frequency increased.CONCLUSIONS The PK/PD simulation is useful to optimize the regimen of anti-infective treatment,and guide its dosing accurately.

Objective To explore the influence on the JNK signal transduction pathway by BaiHui-QuBin Scalp-acupuncture in rats of experimental acute intercerebral hemorrhage. Methods 192 healthy Wistar male rats were assigned into 3groups randomly:model group, model add pinprick group (to abbreviate:pinprick group), model add suppressor group(to abbreviate:suppressor group) ,containing 60 rats in each. All rats were induced be the intercerebral hemorrage model. Another 12 rats were assigned as the matched blank group. The pinprick group were acupunctured on the "Baihui" penetrating "Qubin". The influence surrounding the hamatoma of the proteinum expression of p-JNK of each group in deferent time phase point with the method of Western blot was observed. Results The results of expression of the proteinum p-JNK with the method of Western blot: all the rats after being made model appeared the phenomenon of the expression of p-JNK of rat's brain tissue surrounding the hematoma and increased to the peak in 2 days,but decreased gradually in 7days. In the same time phase point,compared with the model group,the expression of p-JNK of the pinprick group and the suppressor group were lower obviously (P < 0.01). The pinprick group compared with the suppressor group, the expression of p-JNK showed no significant difference (P > 0.05). Conclusion The therapy of BaiHui-QuBin Scalp-acupuncture could block the JNK signal tranaduction pathway, inhibit the expression of the proteinum p-JNK and so on have the function of protecting the nerve cell and inhibiting apoptosis.
