ObjectiveTo investigate the effects of different therapeutic methods on borderline hypertension with metabolic syndrome patients. MethodsNinety borderline hypertension with metabolic syndrome patients were divided into three groups by random digits table with 30 cases: control group,conventional therapy group and intensive therapy group. The control group was given regular observation, the conventional therapy group took drug according to the disease situation; and the intensive therapy group not only formulated the aim of therapy, but also received diet control, sport therapy, healthy education and drug therapy. After 1 year's follow-up, the patients' changes were compared. ResultsAfter 1 year's follow-up,the levels of FPG, 2 h PG, 24 h mAlb and IMT were significantly increased(P ＜ 0.05 ), and the levels of other index had no significant changes (P＞ 0.05) in control group. The levels of FPG,2 h PG,TC and TG were significantly decreased and IMT was significantly increased(P ＜0.05), the levels of other index had no significant changes(P ＞ 0.05 ) in conventional therapy group. The levels of SBP, DBP, PP, FPG, 2 h PG, TC,TG,hs-CRP,24 h mAlb and HOMA-IR were significantly decreased and HDL-C, ABI were significantly increased (P ＜ 0.01 or ＜ 0.05 ) in intensive therapy group. After treatment, the levels of ABI and H DL-C were significantly higher and SBP, DBP, PP,TG, hs-CRP, 24 h mAlb, HOMA-IR, IMT were significantly lower in intensive therapy group than those in conventional therapy group (P ＜ 0.01 or ＜ 0.05 ). ConclusionsDrug therapy is efficient in borderline hypertension with metabolic syndrome patients, and intensive therapy can obviously improve the insulin resistance, to control the developing of hypertension can delay the vascular

Background and purpose:Both nature killer cells(NK)and cytoxic T lymphocytes in the body tissues of human are the dominant components of cellular immunity,This study was done to explore the degree of infiltration of NK/T in lung squamous cell carcinoma and its relation to patient survival and prognosis.Methods: CCD8 as the markers cytoxic T lymphocyte(CTL)and CD56 as the markers natural killer(NK)were stained immunohistochemically to detect the distribution and infiltration in the lung squamous cell carcinoma specimens. Results:In 39 of 68 lung neoplasm,whose CTL infiltration was zero or mild,the five-year survival rate was 18%, while in 29 with marked CTL infiltration,the five-year survival rate was 42%.In 46 of 68 lung neoplasm,whose NK infiltration was zero or mild,the five-year survival rate was 14%,while in 22 with marked NK infiltration,the five-year survival rate was 45%.In 48 of 68 lung neoplasm,both the NK and T cells were zero or mild,the five-year survival rate was 33%,while in 20 with marked NK and T cell infiltration,the five-year survival rate was 54%.The five-year survival difference among the patients with NK,T infiltration either marked or zero/mild infiltration were significant(x~2=18.62, P=0.00).Conclusions:The degree of NK and T infiltration is positively correlated with the prognosis and survival time of lung squamous cell carcinoma patients.

AIM: In order to explore the pathogenesis of ulcerative colitis (UC), an experimental colitis in mouse was induced by the hapten dinitrochlorobenzene (DNCB), and the activity of leukocyte migration inhibitory factor (LMIF) was measured at the same time. METHODS: 67 BALB/c mice were randomly divided into control (60% ethanol) and DNCB groups. After they were sensitized by smearing 3.3% DNCB on the abdominal skin, they were challenged with DNCB at concentration of 0.1%, 0.2% and 0.4% respectively by instillation once a day. The weight, stool viscosity and hematochezia were observed and accumulated as disease active index (DAI) score. The pathological changes in colon tissue were judged macropathologically and by means of microscope. LMIF activity was determined by the absorbance (A) of migrated leukocytes. RESULTS: Compared to control group, the increases in DAI accumulate score, pathologic score, and LMIF activity in DNCB groups were observed. CONCLUSION: Mouse colitis was induced by DNCB, which was accompanied by an increase in LMIF activity. [

Objective to investigate the value of diffusion-weighted echo-planar MR imaging in the diagnosis of head and neck lesions.Methods Fifty-seven patients with 85 head and neck lesions were enrolled in the study,including 22 patients with 22 malignant tumors,13 patients with 13 benign tumors, 13 patients with 17 cystic and liquefactive lesions(including 8 patients with 12 cystic lesions,4 patients with 4 tumor necrosis,1 patients with 1 abcess)and 33 lymph nodes.The lesions were all confirmed by operation and clinical follow up.Echo-planar difffusion-weighted imaging (DWI)was performed with different b values (0,500,and 1,000s?mm~(-2)),and the apparent diffusion coefficients (ADCs)were measured.Results Malignant and benign tumors had different characteristics in DWI with different b values.With the increase of b value,the signal intensity of tumor/spinal cord ratio decreased quickly in DWI in benign tumors,while the signal intensity of tumor/spinal cord ratio remained similar in DWI in malignant tumors.The mean ADC value of'malignant tumors[(0.78?0.24)?10~(-3)mm~2? s~(-1)] was significantly lower than that of benign tumors [(1.48?+0.20)?10~(-3)mm~2?s~(-1)] (t = 8.9,P

The study of small drug molecules interacting with nucleic acids is an area of intense research that has particular relevance in our understanding of relative mechanism in chemotherapeutic applications and the association between genetics (including sequence variation) and drug response. In this contribution, we demonstrate how the sequence-specific binding of an anticancer drug Dacarbazine (DTIC) to single base (A-G) mismatch could be sensitively detected by combining electrochemical detection with biosensing surface based on gold nanoparticles.

Objective To investigate the expression of Nogo-66 receptor (NgR) in primary cultured rat astrocytes.Methods RT-PCR and Western blot were applied to verify mRNA and protein expression of NgR in primary cultured and purified astrocytes. Indirect immunofluorensence and confocal microscopic technique were used to study the distribution of NgR. Results Specific NgR cDNA product could be amplified from the total RNA of primary cultured astrocytes by RTPCR; Western blot of the extracts of astrocytes demonstrated a specific NgR band at about 64 kD. Indirect immunofluorescence and confocal scanning further revealed the intracellular localization of NgR protein in astrocytes. Simultaneously,the NgR protein was detected in C6 rat glioma cells by western blot and immunofluoresence staining. Conclusion NgR is expressed in primary cultured astrocytes, which offers strong and direct support for the expression of NgR in astrocytes in vivo.

AIM: To observe the changes of glycemia and serum cholesterol and triglyceride in diabetic nephropathy rats and therapeutic effects of Xiaoke Keli Ji. METHODS: 3/4 nephrectomy was adopted firstly, three weeks later streptozotocin(STZ) was administered intraperitoneally to establish diabetic nephropathy model in rats. Animals were divided into four groups:model group, Xiaoke Keli Ji treatment group, positive control group and sham group. Changes of serum sugar and serum creatinine, cholesterol and triglyceride were examined at 1, 2, 3, 4, 5 weeks after STZ injection. Renal tissue samples were adopted at 6th week and studied by light microscopy. RESULTS: Model group demonstrated different degree of glomerular sclerosis. Lesions in treatment group were alleviated. Serum creatinine, serum sugar and serum cholesterol were higher at 1, 2, 3, 4, 5 weeks after STZ injection in model group than that of the sham group ( P

OBJECTIVETo analyse the video-oculographic findings of positional tests and evaluate the efficacy of canalith repositioning procedure (CRP) in patients with paroxysmal positional vertigo ( BPPV) of the anterior semicircular canal (ASC).

METHODSA retrospective study of 31 patients with ASC BPPV. Then the CRP was performed.

RESULTSTwenty-two individuals (70.97%) presented a unilateral positional nystagmus during the Dix-Hallpike test, in 17 individuals had torsional nystagmus component, 5 individuals only had pure positional down beat nystagmus. Nine patients presented bilateral positional nystagmus, 7 individuals had torsional component positional nystagmus, in 2 patients the direction of the torsional component were the same during right and left Dix-Hallpike test, in 4 patients the torsional component were concurrent with positional down beat nystagmus but the direction could not be ascertained clinically, in 2 patients had pure positional down beat nystagmus. Nineteen patients (61.29%) had unilateral lesion, 11 patients had the left ASC BPPV, 8 patients had right ASC BPPV. Eleven patients had with both ASC and PSC BPPV in the ipsilateral. Twenty-one patients (67.74%) were cured, 29 patients (93.55%) were improved, 2 (6.45%) patients were inefficacy. CRP effectively resolved the nystagmus and vertigo in 14 patients (45.16%) when applied only once, The average number of CRP was 1.7 times, there were 5 patients recurrence during the follow-up.

CONCLUSIONSASC BPPV was not a common condition. The torsional nystagmus component of ASC BPPV might be weak during the Dix-Hallpike test. The positional nystagmus of ASC BPPV was triggered bilaterally. Based on these findings, CRP could be one of the most effective treatment methods for ASC BPPV.

The prevalence of human papilloma virus (HPV)-16 in patients with cervical cancer, the physical status of HPV-16 in patients with cervical lesions, and the role of HPV-16 integration in cervical carcinogenesis were investigated. HPV genotyping was performed by using PCR approach with the primer GP5+/GP6+ and type-specific primer on biopsy specimens taken operatively from 198 women. Multiple PCR was done to detect physical status of HPV-16 in a series of cervical liquid-based cytology samples and biopsy specimens obtained from different cervical lesions with HPV-16 infection, including 112 specimens with cervical cancer, 151 specimens with CIN I, 246 specimens with CIN and 120 specimens with CINIII. The results showed that there were 112 cervical cancer samples (56.57% of total cervical cancer patients) with HPV-16 infection. The frequency of HPV-16 pure integration was 65.18% (73/112), 56.57% (47/120), 23.58% (58/246) and 7.95% (12/151) in cervical cancer, CINIII, CINII and CINI patients respectively. In situ hybridization was performed on some paraffin-embedded sections of CINII, CINIII and cervical cancer to verify the physical status of HPV-16 infection. Significant difference was observed between cervical cancer and CIN I, CINII, CINIII in the frequency of HPV-16 integration (P<0.01). It is suggested that HPV-16 is the most prevalent type and is associated with cervical cancer. In the case of HPV-16 infection there are close associations between the severity of cervical lesions and the frequency of HPV-16 integration. The application of testing HPV genotyping and physical status based on detection of HC-II HPV DNA would be in favor of predicting the prognosis of cervical precancerosis and enhancing the screening accuracy of cervical cancer.
