OBJECTIVETo investigate the effectiveness of polycystic ovary syndrome (PCOS) of damp-phlegm constitution treated with embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10).

METHODSEighty-five patients were randomly divided into 2 groups of observation group (42 cases) and control group (43 cases). Embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10) were applied to the observation group. Points such as Zhongwan (CV 12), Guanyuan (CV 4), Tianshu (ST 25), Zhangmen (LR 13), Jingmen (GB 25), Qimen (LR 14), Ganshu (BL 18), Weishu (BL 21), Pishu (BL 20), Shenshu (BL 23), Dachangshu (BL 25) and Xiaochangshu (BL 27), etc. were adopted for embedding therapy. At the same time, needle-pricking therapy on Sifeng (EX-UE 10) was also applied once a week. 0. 5 g metformin hydrochloride tablet was given to the control group, once a day for the first week, and twice a day from the second week. Estimation on therapeutic effect was made for both groups after 3 months treatment. Change of symptoms and signs scores, fasting insulin (FINS), 2 hour insulin after meal (2hINS) and insulin resistance index (HOMA-IR) of both groups before and after treatment were observed, and therapeutic effect estimated.

RESULTSThe total effective rate of the observation group is 97. 6% (41/42), and that of the control group was 95. 4% (41/43). There was no significant difference between the two groups (P>0. 05). Scores of symptoms and signs after treatment were significantly improved in both groups (all P<0. 01), and the observation group was better than the control group (7.01+/-4.23 vs 8. 47+/-2. 82,P<0. 05). Compare with those before the treatment, FINS, 2hINS and HOMA-IR after the treatment were all decreased in both groups (all P<0. 05). The comparison between the two groups showed that differences of FIN had no statistic significance (P>0. 05) after the treatment, while both differences of 2hINS and HOMA-IR had statistic significance [ 2hlNS: (443. 531+/- 93. 90) pmol/L vs (621.29+/-93. 87) pmol/L ; HOMA-IR: 4. 88+/-0. 30 vs 5.06+/-0. 32, both P<0. 05]. The improvement of 2hINS and HOMA-IR in the observation group was better than that of the control group.

CONCLUSIONTreatment of PCOS of damp-phlegm constitution with embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10) have positive effect, which can effectively reduce the insulin resistance, meanwhile, reduce the side-effects of western medication.

Objective To study clinical significance of S-100B protein in umbilical cord blood of asphyxial neonates with hypoxic-ischemic encephalopathy(HIE).Methods Forty-three cases of healthy infants were regarded as control group(group 1).Sixty cases of asphyxial neonates were divided into two groups(44 cases without HIE as group 2;another 16 cases with HIE as group 3).S-100B protein levels in umbilical cord blood of three groups were measured with enzyme-linked immunosorbent assay retrospectively. Results Levels of S-100B protein in group 1,group 2 and group 3 were(1.055?0.356) ?g/L,(1.572?0.533) ?g/L and(2.394?(0.943) ?g/L,) respectively.S-100B protein levels in umbilical cord blood of group 2 and group 3 were significantly higher than that of group 1(t=2.306,7.991 P

Objective To investigate the microstructure characteristics in human kidney with the WD cepstrum of ultrasonic backscattering. Methods By using this method, an analysis of the backscattering signals of normal and pathological human kidney in vitro was made and the mean spacing of the scatterers of biological soft tissues was estimated, then compared the means of this new approach with the means of the AR cepstrum. Results The results show that the mean spacings of the scatterers of the two different kidney tissues are noticeably different, which reveals the fact that the WD cepstrum works more effective than the AR cepstrum in showing the features of the microstructure of soft tissues. Conclusion The WD cepstrum is an effective mean to analyze the ultrasonic scattering signals and determine the features of the mean spacing of the scatterers of soft tissues. This method provides more available clinical diagnosis and improves the results of mean spacing of the scatterers of soft tissues.

Objective To explore the mechanism of cerebral infarction caused by hyperhomocystinemia.Methods A hundred and nineteen paitents with acute cerebral infarction were chosen for case group.According to their levels of plasm total homocystine,they were divided into two groups: hyperhomocystinemia group and nonhyperhomocystinemia group.Forty patents without cerebrovascular disease,hepatophy,nephrosis and thyroid gland disease were chosen as control subjects.Plasm levels of total homocystine,serum levels of MDA and IL-8 were measured respectively,their correlations were also studied.Results Plasma levels of tHcy(?mol/L)and serum levels of MDA(nmol/L)and IL-8 (ng/ml)showed a significant increase in case group(19.97,4.41?0.84,0.23?0.08)in comparison with control subjects(9.83,3.24?0.64,0.12?0.08),t values were 8.139,8.021,7.767 respectively(P

Objective To compare the ability of CT and MRI in evaluating the residual of tumor of hepatocellular carcinoma (HCC) and its stability after treated by transcatheter arterial chemoembolization (TACE) with Lipiodol.Methods 28 patients with HCC underwent CT, MRI and angiography within 2～6 months after 1～4 procedure(s) of TACE. These three examinations were completed sequentially within one month. CT and MRI findings were thus compared on the basis of the results of arteriography and clinical follow-up at least 6 months.Results 46 lesions were found in 28 patients. 31 lesions with and the other 15 lesions without residual viable tumor were confirmed by arteriography and clinical follow-up. 20 lesions with and 26 lesions without residual viable tumor were found on CT images, and CT displayed 64.5% sensitivity, 100% specificity, and 76.1% accuracy respectively. 29 lesions with and 17 lesions without residual viable tumor were found on MRI images, and its sensitivity, specificity, and accuracy were 93.5%, 100%, and 95.7% respectively. The sensitivity and accuracy between CT and MRI in evaluating the residual viable tumor of HCCs after TACE were significant different(?

Cornea is the major refractive components of the eye. As a viscoelastic tissue, cornea exhibits complicated biomechanical properties: non - linear elasticity, anisotropy and viscoelasticity. The biomechanical properties play an important role in keeping the normal structureand function. Changes in biomechanical properties are always earlier than the clinical symptoms. So quantitative measurement of the biomechanical properties benefits the early diagnosis and treatment of diseases. Different methods to measure the biomechanical properties of cornea were reviewed in detail, including classic ex vivo destructive tests, commercially available in vivo measuring methods and other emerging methods with the potential for clinical application but not validated for in vivo measurement. The operating principles, advantages as well as limitations of these methods were also described.

Objective To investigate the effect of Kanglaite injection (KLT) on immunological function of rat models with Lewis lung carcinoma. Methods Forty C57BL/6 mice were used to establish Lewis lung carcinoma models and divided randomly into the high dose(25 mL/kg), middle dose (12.5 mL/kg) and low dose (6.25 mL/kg) of KLT groups and model group(n=10). The mice in the KLT groups were sacrificed after injecting corresponding dose of KLT with intraperitoneal injection for 14 d. No treatment was performed on the rats in model group. The body weight, tumor and spleen weight was weighed, then the ratio of tumor restriction and the index of spleen was calculated. MTT colorimetric method and ELISA were used to detected activity of T cell proliferation and expression of IL-2 in spleen. The expression of NF-κB and IκBα protein was detected by Western blot. Results The ratio of tumor restriction in the high, middle, low dose of KLT groups decreased gradually. The indexes of spleen of the high and middle dose of KLT groups were higher than those in the model group (P<0.05 or P<0.01).Compared with the model group, the activity of T cell proliferation in the high, middle, low dose of KLT groups and the expression of IL-2 in the high and middle dose of KLT groups was increased significantly (P<0.05 or P<0.01). The expression of NF-κB protein in the nuclei of high, middle, low dose of KLT groups increased dose-dependently, and the expression of NF-κB and IκBα protein in the cytoplasm decreased dose-dependently. ConclusionKLT could enhance immunological function by effecting T cell proliferation, expression of IL-2, NF-κB and IκBα, while restricting tumor growth in Lewis lung carcinoma models.

Objective To analyze the laboratory detection findings in infectious mononucleosis(IM) and mucocutaneous lymphnode syndrome(MCLS)and find the main points of the differential diagnosis and direct the treatment. Methods Five hundreds and twenty-five children were in-patient department over these past 10 years .These patients were divided into 2 groups,IM group (225 patients) and MCLS group(280 patients). EB-virus antibody,Paul-Bunnell test,the circumference blood numeration ,classification of leucocytes,the numeration of atypical lymphocytes were detected and compared,as well as blood platelet of these patients.Results The positive rate of EB-virus antibody in IM and MCLS were high, and had no discrepancy. However, the positive rate of Paul-Bunnell test and numeration of atypical lymphocyte in IM group were significantly higher than those in MCLS group. The total circumference blood leucocyte numeration of the groups increased,but the numeration neutrophil increased significantly in MCLS group, the rising numeration of lymphocyte in IM; the blood platelet numeration was elevated significantly in MCLS group and continued when the total circumference blood leucocyte numeration tended normally.Conclusions The causes of IM and MCLS are related to the infection of EB-virus. The laboratory characteristics of IM and MCLS are different,understanding the main points of the differential diagnosis contributes to the clear diagnose and early treatment.

AIM:To research the effects of Kanglaite(KLT)injection on antitumor and expression of epidermal growth factor receptor(EGFR)in Lewis lung carcinoma(LLC).METHODS:A total of 40 C57BL/6 mice were randomly divided into four groups,including model group,KLT 6.25,12.5,25 mL/kg groups.All the mice were injected with 2?106 LLC cells at 1st day.At the next day,mice in the KLT groups were peritoneally injected with KLT for 14 days.And at the 16th day,all the mice were sacrificed and the tumors were harvested.The tumor weight was measured and the tumor growth inhibition rate was analyzed.The expression of EGFR was detected by westernblot.RESULTS:The growth of LLC was significantly inhibited by KLT,the changes of tumor appearance and histology were affected and the expression level of EGFR was decreased.CONCLUSION:KLT injection could obviously inhibit the growth of LLC,whose mechanism maybe related to the inhibition of EGFR expression.
