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 study the effects of Box-3 region of the leukemia inhibitory factor receptor (LIFR) alpha-chain cytoplasmic domain on the proliferation and differentiation of HL-60 cells.

METHODSExpression vector of gp190CT3 was constructed and expressed in HL-60 cells. The expression level of gp190CT3 was assayed by immunocytochemistry. The growth of wild type and gp190CT3 transfected HL-60 cells were examined under microscope. The PCNA levels were assayed by Western blot, and the levels of CD15 by flow cytometry.

RESULTSThe gp190CT3 transfected HL-60 cells were enlarged in size and their proliferation was slower than that of wild type. The expression level of PCNA was down-regulated while the level of CD15 up-regulated in transfected HL-60 cells as compared with that of the wild type cells.

CONCLUSIONThe Box-3 region of the leukemia inhibitory factor receptor alpha-chain cytoplasmic domain (gp190CT3) participates the LIFR signal transduction in inhibiting the growth and inducing the differentiation of HL-60 cells.

OBJECTIVETo analyze the maltose clearance in plasma and urine of healthy volunteers with high-performance liquid chromatography.

METHODSMaltose solution was infused to 12 healthy volunteers during a 4-hour period at an infusion rate of 0.2, 0.3, and 0.5 g/(kg x h), Plasma and urine specimens were collected at different time points before and after infusion, and then analyzed with high-performance liquid chromatography.

RESULTSThe coefficients of variation of the precision and accuracy of the analysis method ranged 3.68%-4.58% and 0.44%-4.83% for plasma, respectively, and 2.91%-7.62% and 0.95%-8.27% for urine, respectively. The plasma maltose concentration increased in a dose-dependent manner (r > 0.99). The plasma maltose concentrations returned to the baseline levels 12 hours later. Two hours after injection, the urinary excretion of maltose increased, reached the peak value within 2-4 hours, began to decrease 6 hours later, and became zero 24 hours later.

CONCLUSIONSAn infusion rate of 0.2-0.5 g/(kg x h) of maltose will not remarkably increase the blood glucose level in healthy people. The routine infusion rate should below 0.3 g/(kg x h), unless an emergency exists.

OBJECTIVETo observe the impact on lower limbs balance function in treatment of yin-yang meridians acupuncture with respiratory reinforcing and reducing manipulation involved in the patients of stroke by applying B-PHY balance function test training system so as to provide the objective evidence in treatment of stroke; with acupuncture.

METHODSOne hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the basic treatment was applied, without other relevant rehabilitation therapies associated. In the observation group, with the basic treatment as the control group's, the therapy of the yin-yang meridians acupuncutre with respiratory reinforcing and reducing manipulation was adopted. On the yin meridians, Zuwuli (LR 10), Xuehai (SP 10), Yinlingquan (SP 9), Sanyinjiao (SP 6) and the others were selected and stimulated with reducing manipulation achieved by the coordination of patient's respiration. On the yang meridians, Biguan (ST 31), Liangqiu (ST 34), Yanglingquan (GB 34) and the others were selected and stimulated with reinforcing manipulation achieved by the coordination of patient's respiration. The treatment was given once a day and for 28 days totally. Before treatment and in 28 days of treatment, B-PHY balance function test training system was used to determine the weight shift track parameters (track length, peripheral square, track length of per unit square, left-right offset and rectangle square), the weight shift track distance parameters [mean of X axle weight shift distance (Mean-X), mean of Y axle weight shift distance (Mean-Y), maximum of X axle weight shift distance (Max-X), maximum of Y axle weight shift distance (Max-Y), weight shift distance (LSKG), weight shift square (SSKG), square ratio of weight shift (LFS)], stability coefficient (SI) and weight distribution coefficient (WDI).

RESULTSAfter treatment, the differences in the weight shift track parameters, SI and WDI were significant as compared with those before treatment in the patients of the two groups (all P<0.01); while the differences in the weight shift distance parameters in the observation group were improved obviously after treatment as compared with those before treatment (all P<0.01), the differences of Mean-X, Max-Y and LFS in the control group were improved after treatment as compared with those before treatment (all P<0.01). Except SSKG, the improvements after treatment in the rest indices in the observation group were better than those in the control group (all P<0.05).

CONCLUSIONThe yin-yang meridians acupuncture with respiratry reinforcing and re- ducing manipulation effectively improves the lower limbs balance function in the patients of stroke.

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.

Objective To observe the efficacy difference between different needling manipulations in treating acute stroke with point-toward-point needling at scalp acupoints, for seeking the optimal treatment protocol. Method Ninety patients with acute stroke were randomized into a manual needling group, an electroacupuncture group, and a needle-retaining group, 30 cases each. In addition to the neurological treatment, the three groups were all given point-toward-point needling from Baihui (GV20) to Taiyang (EX-HN5) on the affected side, respectively with manual twisting, electroacupuncture and needle retaining methods. Before and after 14-day treatment, the Neurological Deficit Score (NDS), level of neuron specific enolase (NSE) and total efficacy were compared among the three groups. Result The NDS dropped significantly in the three groups after the intervention (P<0.05); the manual needling group showed the most significant improvement, better than the electroacupuncture group and needle retaining group. The level of NSE declined significantly in the three groups after the intervention (P<0.05); the decrease in the manual needling group was the most significant compared to that in the electroacupuncture group and needle retaining group. The total effective rate in the manual needling group (90.0%) was significantly higher than that in the electroacupuncture group and needle retaining group (P<0.05). Conclusion Point-toward-point needling at scalp acupoints with manual operation can effectively improve the neurological deficit in stroke patients, and the application of needling manipulations can further enhance the therapeutic efficacy, which is specific.
