Objective The present study is to investigate the influence of vaginal discharge on dry chemistry determination of leukocyte esterase in female urine.Methods Collected 20 and 30 normal vaginal discharge samples.Which humoral routine test degree were Ⅰ and Ⅱ correspondingly,and then analyze leukocyte esterase and squamous epithelial cells in these normal vaginal discharge samples.Collected normal vaginal discharge samples again and isolate the vaginal squamous epithelial cells from those normal vaginal discharge samples.Made two concentration of squamous epithelial cell suspension liquid (20/μl and 60/μl)and added these liquid.To normal female urine and analyze the drying chemical leukocyte esterase in those urine. Cleaned the vulva of those patients with normal leukocyte counts in urine sediment determination,whose dry chemical deter-mination of leukocyte esterase was strong positive,perform the routine urine test with her middle urine.Results The results of the determination of leukocyte esterase in normal vaginal discharge samples were 66.7% positive.And there were ~squamous epithelial cells in all samples (microscopy).No significant difference was observed in the examination of dry chem-istry leukocyte esterase among the normal female urine group,low (20/μl)and high (60/μl)concentrations of squamous epi-thelial cell urine group (P >0.05).The counts of squamous epithelial cells and the rate of positive and intensity of dry chem-ical leukocyte esterase in the middle of second urine were significantly lower than before,and the differences are statistically significant (P <0.05).But there was no significant difference for leukocytes counts.Conclusion Urine squamous epithelial cells had no influence on the detection of leukocyte esterase by dry chemistry.However,the leukocyte esterase in the vaginal discharge greatly influenced the examination of the leukocyte esterase in urine.

Objective To compare the treatment effect of laparoscopic appendectomy(LA) and open appendectomy (OA). Methods One hundred and forty-five cases of LA performed from May 2003 to May 2005, and 142 cases of OA performed from June 2001 to March 2003 were studied retrospectively. Results There was no difference in operative time between group LA and group OA. In the procedure of LA, some occult disease could be discovered and treated, while OA was not. The administration of analgesic, activity time, incidence of incision infection and hospital stay in group LA were better than those of OA group. While the cost of hospitalization in LA was higher than that of OA. Conclusion LA has significant advantages in treating appendicitis and it should be promoted.

Objective To compare the enhancement characteristic of the gallbladder diseases and to evaluate the diagnostic efficacy in differential diagnosis of the gallbladder diseases between contrast-enhanced sonography (CEUS) and contrast-enhanced computed tomography (CECT).Methods Seventy-two patiens with gallbladder lesions were examined by CEUS and CECT before operation and all final diagnoses were confirmed by surgery and/or pathological diagnosis.Results 1)In early phase,84.6％ (33/39) and 79.5％ (31/39) of benign diseases showed hyper-enhancement on CEUS and CECT,and 97.0％ (32/33) and 87.9％ (29/33) of malignant diseases showed hyper-enhancement on CEUS and CECT respectively (P =0.250).In later phase,91.2％ (31/34) and 88.2％ (30/34) of benign diseases showing hypo-enhancement (P =1.000),and 100％ of the malignant diseases showing hypo-enhancement on CEUS and CECT respectively.2)The time of enhancement from hyper-to hypo in CEUS for benign and malignant diseases were (39.9 ± 15.7)s and (29.9 ± 5.6)s respectively (t =3.61,P =1.000).3)The inhomogeneous enhancement on CEUS and CECT were 41.0％ (16/39) and 53.8％ (21/39) in the benign diseases respectively (P =0.063),84.8 ％ (28/33) and 97.0 ％ (32/33) in the malignant diseases respectively(P =0.125).4)The destruction of the gallbladder wall on CEUS and CECT are 87.9％ (29/33) and 90.9％ (30/33) respectively(P =1.000).5)The accuracy,diagnostic sensitivity,specificity of CEUS and CECT were 91.7％(66/72) and 87.5％(63/72),97.0％(32/33) and 93.9％(31/33),87.2％(34/39) and 82.15％ (32/39) respectively (P =0.250,1.000,0.500).Conclusions The enhancement pattern of the gallbladder diseases on CEUS and CECT were much similar.CEUS has equal diagnostic efficacy in comparison with CECT,but CEUS can supply more diagnostic information than CECT.

Objective To explore the diagnostic value of human telomerase reverse transcriptase (hTERT) and proliferating cell nuclear antigen (PCNA) in pleural and peritoneal effusion. Methods The expressions of hTERT and PCNA were detected by immunocytochemistry in 46 malignant and 21 benign serous specimens. Results hTERT and PCNA were detected respectively in 39 and 29 of 46 malignant specimens, but no expressions in reactive mesothelial cells in all serous specimens. hTERT correlated with PCNA (r=0.30, P

Pathohistological observations on the soft tissue wounds experimentally produced with steel-bullets of three different weights and 8 different velocities were carried out on 42 dogs. It was found that if the weight of the bullets was identi- cal while their velocities were different, the severity of the injury and the extent of the contusion zone were directly related to the velocity of the bullet. The characteristic feature was that the injury at the entrance of the bullet was more severe than that at the exit. It might be resulted from the fact that the energy of the bullet was rapidly delivered soon after it penetrated the skin because of its light weight and the high resistance of the tissues.

AIM: To investigate the effect of microwave ablation of liver cancer on the cellular immunity in mice. METHODS: A C57BL/6J mouse model of liver cancer was established by subcutaneous injection of Hepa 1 - 6 cells. The tumors were subjected to microwave ablation under the ablation condition of 45 ℃, 50 ℃, 55 ℃ or 60 ℃ for 180 s. The CD4~+ T cells, CD8~+ T cells and natural killer cells (NK) in peripheral blood were detected by FACS. The cytotoxicity of splenic NK and splenic cytotoxic T lymphocytes (CTL) activated by inactivated Hepa 1-6 cells was assayed by LDH method. RESULTS: The proportions of CD4~+ T cells, CD8~+ T cells and NK cells in peripheral blood in 50 ℃ and 55 ℃ group at 21 d after ablation were significantly increased and that of NK cells in 60 ℃ group was significantly increased. There was no significant difference between those in group 42 d after ablation and control. The cytotoxicities of splenic CTL and NK cells in 50 ℃ and 55 ℃ groups at 21 d or 42 d after ablation were significantly increased, and they were much higher than those in 45 ℃ group at the same time. The cytotoxicities of splenic CTL in 50 ℃ and 55 ℃ groups at 21 d after ablation were much higher than that in 60 ℃ group at the same time. CONCLUSION: Under a certain ablation temperature, microwave ablation of liver cancer promotes the cellular immunity.

AIM: To detect the change of composition and ratio of serum HDL subclasses and explore the relationship between these changes and the plasma lipid level in patients with hyperlipidemia. METHODS: The components of subclasses of serum HDL in 172 middle and old aged patients with hyperlipidemia and 115 healthy middle and old aged were determined by dimensional gel electrophoresis associated with immuno-blotting method. RESULTS: Compared to the healthy controls, the contents of pre ?_1-HDL, HDL_~3b and HDL_~3a were significantly higher (P

Objective To evaluate ultrasound-guided percutaneous ablation for recurrent hepatocellular carcinoma.Methods In this study, 141 patients with recurrent hepatocellular carcinoma (628 lesions) were treated by percutaneous ablation therapies, including microwave, radiofrequency, ethanol injection and hot distilled water ablation.Results The complete ablation rate was 92.0% (578/628) in this group, and was 96.3% ( 105/109 )? 92.9%(119/128)? 91.5% (311/340) and 84.3% (43/51), respectively, for microwave, radiofrequency, ethanol and hot distilled water ablation subgroups.The local recurrence rate was 13.5% ( 78/578 ), and was 11.4% (12/105)? 13.4% (16/119)? 11.9% (37/311) and 30.2% (13/43), respectively, for microwave, radiofrequency, ethanol and hot distilled water ablation subgroups.After a follow-up period of 2-66 months, liver function remained unchanged in 117 patients (81%) after ablation therapies.Patients were followed-up for 2-66 months, the 1, 3 and 5-year survival rate was 75%, 53% and 26%, respectively.Conclusion Ultrasound-guided percutaneous ablation therapies for recurrent hepatocellular carcinoma are safe and effective, while incuring minimal damage to liver function and improving long-term survival.
