Objective To investigate the relationship of circulating zinc-α2-glycoprotein (ZAG) as well as adiponectin with adiposity and insulin resistance in humans.Methods Serum ZAG and adiponectin levels were determined by ELISA in 285 subjects with normal glucose tolerance (NGT),impaired glucose tolerance (IGT),and newly diagnosed cases with type 2 diabetes mellitus(T2DM).The relationships between circulating ZAG and insulin resistance or metabolic parameters were also explored.Results Circulating ZAG and adiponectin levels were all lower in T2 DM and IGT subjects than those in control subjects [ZAG:(37.14 ± 13.25 and 48.84 ± 18.74 vs 59.36 ± 16.20) mg/L,P＜0.05 or P＜0.01 ; adiponectin:(27.79 ± 11.23 and 33.00 ± 9.42 vs 41.81 ± 13.68) μg/L,P＜0.01].Circulating ZAG was correlated positively with high density lipoprotein-cholesterol and adiponectin (all P＜0.01),and inversely with body mass index,waist-hip ratio,FAT％,diastolic blood pressure,triglyceride,fasting blood glucose,fasting insulin,HbA1C,and homeostasis model assessment for insulin resistance(HOMA-IR,P＜0.05 or P＜0.01).By multivariate analysis,ZAG levels were independently associated with body mass index,HOMA-IR,diastolic blood pressure,and adiponectin (P＜0.05 or P＜0.01).Conclusions ZAG levels,associated with fat,insulin sensitivity,and adiponectin expression,are likely to play an important role in insulin resistance and energy homeostasis in humans.

ObjectiveTo analyze the clinicopathologic features of hereditary cutaneomucosal venous malformation (VMCM) in a Chinese family.MethodsFamily history was investigated in a family with VMCM,and tissue specimens were obtained from the lesions of the proband and subjected to histopathological analysis.ResultsAmong 65 members from 5 generations of the family,19 were affected by VMCM,hinting an autosomal dominant inheritance.None of the family members experienced gastrointestinal bleeding,central nervous system disorders,or cardiac defects.Affected individuals usually presented with multiple irregularly sized,blue-violet,elevated and slightly indurated masses located in the oral mucosa and subcutaneous tissue of the extremities.Pathological analysis showed malformed veins with abnormally dilated cavities and irregularly thickened walls.Although small veins were abnormally proliferating and clustered,there was no endothelial discontinuity.The smooth muscle layer was thickned in a varying degree or absent.ConclusionA diagnosis of VMCM is made according to the inheritance manner,clinical manifestation and pathological findings.

OBJECTIVETo explore the relationship between alcohol intake and traditional Chinese medicine Syndrome type in patients with cardio-cerebral diseases.

METHODSStudy was conducted in 1013 selected inpatients with myocardial infarction (MI) or/and cerebral infarction (CI) by logistic multivariate regression analysis and comparison among groups.

RESULTSThe scores of blood stasis syndrome showed a decreasing tendency along the increasing of alcohol intake, but it cannot prove that taking alcohol could prevent blood stasis. The scores of dampness-heat syndrome increased in patients who had chronically taken alcohol in large dose.

CONCLUSIONDampness-heat syndrome induced by alcohol is one of the basic mechanisms of cardio-cerebral diseases. Alcohol intake should be restricted.

PURPOSETo investigate the clinical significance and management of ASCUS/LSIL.

METHODS254 patients who were examined with cervical cytology in the Cancer Institute and Hospital Chinese Academy of Medical Sciences were ASCUS/LSIL, of whom 136 cases underwent colposcopy, Data were analyzed retrospectively according to the golden criterion of pathology outcome.

RESULTS140 cases were ASCUS, and 114 cases were LSIL. Cervical intra-epithelial neoplasia (CIN) were diagnosed in 51.5% of patients with ASCUS, compared with 59.6% of patients with LSIL (P>0.05). High-grade cervical intraepithelial neoplasia were diagnosed in 22.9% of patients with ASCUS, compared with 30.7% of patients with LSIL (P >0.05). In the 136 patients examined with colposcopy, inflammation was found in 47 cases, low-grade intraepithelial lesion in 53 cases, High-grade intraepithelial lesion in 36 cases. The pathological results show inflammation in 55 cases, low-grade intraepithelial lesion in 41 cases, High-grade intraepithelial lesion in 40 cases (Kappa=0.314, U=0.064, P less than 0.05). CIN were diagnosed in 79% (67/84) of HPV-positive patients identified by pathology, compared with 43.5% (74/170) of HPV-negative patients (chi2=29.88 P less than 0.05). 83.5% of 254 patients were between 35 to 55 years old, and that was consistent with HPV-positive women age peak.

CONCLUSIONPatients with ASCUS should be paid the same attention with LSIL patients and colposcopy examination should be done immediately to avoid missed diagnosis and missed follow-up examination, especially for HPV positive patients between 35 to 55 years old.

OBJECTIVETo investigate the expression of human epididymal secretary protein 2 isoform human epididymal protein 2beta1(HE2beta1) in the testis and epididymis of adolescent male rats along with its significance.

METHODSImmunohistochemical staining was used to detect the expression and localization of HE2beta1 in the testis and epididymis of 15 adolescent SD rats.

RESULTSHE2beta1 immunoreactive staining was detected in the testis and epididymis. In the epithelia of the epididymal duct, HE2beta1 expressed mainly in the supranuclear region of the principle cells and the basement membrane of some epithelial cells; there were no immunostaining in the n clear cells, halo cells and basal cells. The immunopositive reaction was detected, weak in the distal caput, strong in the proximal, middle corpus and the cauda, but negative in the initial segment. Immunopositive results of HE2beta1 were also observed in some of the nuclei of spermatogonia and Sertoli cells with negatively-stained cytoplasm.

CONCLUSIONImmunohistochemical staining is a fairly sensitive method for detecting HE2beta1 expression. The localization and expression level of HE2beta1 in the genital duct of adolescent male rats exhibited a region- and cell-specific expression pattern, which suggests that HE2beta1 may play an important role in spermatogenesis, maturation and epididymal epithelial innate defense mechanisms.

OBJECTIVETo compare the difference in the efficacy on gait time cycle of ischemic stroke between yin-yang respiratory reinforcing and reducing needling technique (yin-yang needling) and the conventional acupuncture.

METHODSSixty cases of ischemic stroke were randomized into a conventional acupuncture group and a yin-yang needling group, 30 cases in each one. The basic treatment (the control of blood pressure, blood sugar and blood lipid, the intravenous drops of ginkgo leaf extract and dipyridamole injection and vinpocetine injection) were applied in the two groups. Additionally, in the conventional acupuncture group, the acupoints of the Stomach Meridian of Foot-Yangming [Biguan (ST 31), Liangqiu (ST 34), Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39), etc.] were selected and stimulated with the even needling technique. In the yin-yang needling group, the acupoints of yin meridians such as Zuwuli (LR 10), Xuehai (SP 10), Yinlingquan (SP 9) and Sanyinjiao (SP 6), etc. and the acupoints of yang meridians such as Biguan (ST 31), Liangqiu (ST 34) and Yanglingquan (GB 34), etc. were selected. The reducing manipulation of respiratory reinforcing and reducing technique was applied to the acupoints of yin meridians and the reinforcing manipulation was applied to the acupoints of yang meridians. The kinematics time parameters were determined and compared before and 4 weeks after treatment.

RESULTSAfter treatment, the differences in the gait cycle, the phase time of standing (%), the phase time of single support (%), the phase time of unilateral sway (%) on the affected (healthy) foot and phase time of double support (%) were significant as compared with those before treatment in the patients of the two groups (all P < 0.05), in which, the gait cycle (1.75 +/- 0.21 vs 2.02 +/- 0.37), the phase time of standing (%) on the affected (healthy) foot [(65.41 +/- 5.20)% vs (68.37 +/- 6.24)%, (70.99 +/- 6.47)% vs (74.51 +/- 5.19)%], the phase time of unilateral sway (%) on the affected (healthy) foot [(36.08 +/- 4.86)% vs (33.65 +/- 2.94)%, (31.04 +/- 3.41)% vs (26.77 +/- 2.67)%] and the phase time of double support (%) [(36.91 +/- 5.10)% vs (41.22 +/- 5.39)%] in the yin-yang needling group were improved much obviously after treatment as compared with those in the conventional acupuncture group. The differences in support phase time (%), single support phase time (%) and sway phase time (%) were significant between the affected limb and healthy limb of the two groups after treatment (all P < 0.05).

CONCLUSIONYin-yang respiratory reinforcing and reducing needling technique effectively improves hemiplegic gait movement cycle and walking function in patients of ischemic stroke, which is superior to the conventional acupuncture treatment.

OBJECTIVETo assess the value of contrast-enhanced ultrasound imaging in monitoring the therapeutic effect of argon-helium cryosurgical treatment of malignant tumors.

METHODSBefore and after argon-helium cryosurgical treatment, 42 patients underwent contrast-enhanced ultrasound imaging, conventional ultrasound imaging and enhanced CT or magnetic resonance imaging (MRI) for examining the number of tumor foci and the size of necrotic areas.

RESULTSA total of 80 tumor lesions were detected by contrast-enhanced ultrasound imaging. Compared with conventional ultrasound imaging, contrast-enhanced ultrasound imaging detected a significantly greater number of tumors and the intratumoral necrotic areas (96 vs 19) as well as a significantly increased mean size of necrotic areas (5.7∓3.6 cm vs 2.8∓1.7 cm), showing no significant differences from the results by enhanced CT and MRI (94 and 5.5∓3.3 cm, P=0.872 and 0.978, respectively). The short-term therapeutic effect of argon-helium cryosurgery evaluated by contrast-enhanced ultrasound imaging were also similar to that assessed by enhanced CT or MRI (P=0.906).

CONCLUSIONContrast-enhanced ultrasound imaging has important values in monitoring malignant tumors during argon-helium cryosurgical treatment and in evaluating the short-term therapeutic effect of the treatment.

OBJECTIVETo evaluate the serum concentrations of E- selectin, integrinbeta(1) subunit and intercellular adhesion molecule-1 in gastric cancer patients and their clinicopathological significance.

METHODSThe serum levels of adhesion molecules E- selectin,intercellular adhesion molecule- 1 (ICAM- 1), and integrinbeta(1) were measured by enzyme-linked immunosorbent assay (ELISA) in 47 health subjects (control group) and in 57 patients with gastric cancer (gastric cancer group) before operation and 7 days after operation. Serum levels of above three factors were compared between the two groups.

RESULTSThe serum concentrations of E- selectin, integrinbeta(1) subunit and ICAM- 1 were higher in gastric cancer group with positive rate of 24.6% ,33.3% ,28.1% respectively. ICAM- 1 and integrinbeta(1) were significant higher in gastric cancer group than that in the control group (P< 0.01),but there was no significant difference in E- selectin between two groups (P=0.64). Serum concentrations of E-selectin, ICAM-1,and integrinbeta(1) were significantly correlated with clinicopathological features as following: clinicopathological stage,invasion depth,lymph node involvement,and presence of distant metastases(P< 0.05,P< 0.01). The serum levels of E- selectin, ICAM- 1, and integrinbeta(1) were decreased significantly after radical resection of gastric cancer,but not in patients with unresectable tumor. Elevated levels of three molecules were significant prognostic factors for patients with gastric cancer,but it could not independently be used to evaluate tumor stage.

CONCLUSIONSSerum concentrations of E- selectin, ICAM- 1,and integrinbeta(1) may reflect tumor progression and metastasis.
