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.

OBJECTIVETo explore the effect of microneedle combined with Lauromacrogol on skin capillary network.

METHODS24 male Leghone (1.5-2.0 kg in weight) were randomly divided into three groups as group A (microneedle combined with Lauromacrogol), B (microneedle combined with physiological saline) , and C(control). The cockscombs were treated. The specimens were taken on the 7th, 14th, 21th , and 28th day postoperatively. HE staining, immunohistochemical staining and special staining were performed for study of the number of capillary and collagen I/III , as well as elastic fibers.

RESULTSThe color of cockscombs in group A became lightening after treatment. The number of capillary decreased as showing by HE staining. The collagen I and III in group B was significantly different from that in group A and C (P < 0.05). Special staining showed proliferation of elastic fibers in group B.

CONCLUSIONSIt indicates that microneedle combined with Lauromacrogol could effectively reduce the capillary in cockscomb without any tissue fibrosis. Microneedle can stimulate the proliferation of elastic fiber, so as to improve the skin ageing process.

Objective To investigate the features of hepatic angiomyolipoma(AML) on contrast enhanced ultrasound (CEUS). Methods Ten pathologically proved AML lesions in 9 patients were evaluated by using baseline ultrasound and CEUS. CEUS was performed with contrast pulse sequencing technique and the contrast agent of SonoVue. Results On baseline ultrasound, 7 lesions exhibited mixed echoic,which was obvious hyperechoic combined with partly of hypoechoie; 3 lesions exhitited obvious hypereehoic. On color Doppler flow imaging artery signals were detected in all lesions. And the lesions had plenty or slightly plenty of artery supply,with resistive index about 0.53 4±0.10 (0.48~0.62). On CEUS, in the arterial phase, 9 lesions exhibited hyper-enhanced. In the portal phase, 5 lesions exhibited iso-enhancement,1 lesion was slightly hyper-enhancement and 3 lesions was hypo-enhancement. In the late phase 6 lesions were iso-enhancement and 3 lesions were hypo-enhancement. One lesion was all hypo-enhancement in all three phases. Conclusions There are some characteristic manifestations of hepatic AML in CEUS, which are helpful for the diagnosis of hepatic AML in a way,but we still need more experiences.

Objective To study the clinical curative effect of Tongqiao Huoxue decoction combined with edaravone and hyperbaric oxygen for treatment of delayed encephalopathy after carbon monoxide poisoning (DEACMP). Methods A prospective study was conducted. Forty-six patients with DEACMP admitted into Yidu Central Hospital of Weifang Medical College from January 2012 to January 2014 were randomly divided into observation group (23 cases) and control group (23 cases). The basic treatments of two groups were identical. Based on the basic treatments including hyperbaric oxygen and citicoline sodium injection etc, the observation group was treated with our-self made Tongqiao Huoxue decoction which could be modified in accord to the individual differentiation of syndromes in traditional Chinese medicine (the composition of decoction included Paeoniae Radix Rubra 15 g, Chuanxiong Rhizoma 15 g, Persicae Semen 15 g, Carthami Flos 15 g, Zingiberis Rhizoma Recens 3 pieces, Jujubae Fructus 2 pieces, Moschus 0.5 g, Allium Fistulosum 1 segment). The decoction was administered orally or by nasogastric gavage, one dosage everyday for 1 month, and in the mean time, edaravone intravenously drip 30 mg was given to the observation group twice a day for 14 days. The control group was given hyperbaric oxygen and other conventional treatment for 30 days. The clinical therapeutic effect and adverse reaction were observed after treatment for 30 days. The changes of intelligent level were detected by Hasegawa dementia scale (HDS), and the changes of latency of P300 were measured by electromyologram/evoked potential instrument in two groups before and after treatment. Results The total effective rate in observation group was significantly higher than that in control group [91.3% (21/23) vs. 65.2% (15/23), P < 0.01]. Elevation of creatinine occurred in 1 case, moderate increase in alanine aminotransferase (ALT) appeared in 1 case, and both of them were reduced to normal after treatment in observation group; no adverse reaction occurred in control group. The HDS scores were significantly higher 30 days after treatment than those before treatment in the two groups [control group:13.4±2.8 vs. 6.8±2.3, observation group:20.8±3.4 vs. 6.6±2.5, both P<0.05]. The latency of P300 after treatment was significantly lower in two groups than that before treatment [control group (ms): 355.7±25.7 vs. 385.5±27.8, observation group (ms): 337.3±24.6 vs. 386.8±25.4, both P < 0.05], the change in observation group being more significant [the HDS score: 20.8±3.4 vs. 13.4±2.8, the latency of P300 (ms): 337.3±24.6 vs. 355.7±25.7, both P<0.05]. Conclusion Tongqiao Huoxue decoction combined with edaravone and hyperbaric oxygen has favorable cognitive effect on patients with DEACMP, thus, it can be used extensively in clinic.
