Objective To explore the expression of c-met mRNA in nasopharyngeal carcinomas(NPC) and its relation with clinical biological behavior. Methods In situ hybridisation was used to detect mRNA expression of c-met in 15 cases NP and 55cases NPC. Results The positive rate of c-met mRNA in NP and NPC cells were were 13.3 %(2/15) and 61.8 %(34/55) respectively. The expression of c-met mRNA was significantly correlated with lymphnode metastasis, local invasion(basilar destroying) (P 0.05). Conclusions The abnormality expression of c-met gene expression was well correlated with the biological behavior of metastasis and invasion. The expression of c-met mRNA could serve as an important index to estimate the prognosis of NPC. c-met may be a new diagnostic/therapeutic targert of NPC.

Objective To investigate the association between serum homocysteine (Hcy) level and oxidative stress in elderly patients with obstructive sleep apnea/hypopnea syndrome (OSAHS). Methods The 123 patients from January 2007 to June 2010 were recruited and divided into the elderly OSAHS group (n=55) and the non-elderly OSAHS group (n=68). One hundred healthy subjects were selected and divided into the elderly control group (n=52) and the non-elderly control group (n=48). The PSG variables were recorded and the levels of Hcy, malondialdehyde (MDA) and glutathione (GSH) were detected after sleep in all subjects. Serum Hcy level was measured by cyclophorase, MDA and GSH levels were measured by spectrophotometer. Results There were statistical differences in Hcy concentration between four groups (F=28.26, P=0.000). The Hcy concentration was higher in elderly OSAHS group than in other groups, and was higher in elderly control group than in non-elderly control group, and was higher in non-elderly OSAHS group than in non-elderly control group. There were statistical differences in MDA and GSH concentrations between the four groups (F=5.56, P=0.002;F=4.79, P=0.004). The concentrations of MDA and GSH were higher in elderly OSAHS group than in other groups. Multiple regression analysis indicated a statistically significant relationship of Hcy concentration with age, MDA, GSH and AHI (β=0.07, 0.50, 0.23 and 2.00). Conclusions The concentration of Hcy increases and oxidative stress enhances with aging, especially in the elderly patients with OSAHS. The mechanism of high level of serum Hcy in elderly patients with OSAHS may be the high oxidative stress.

ObjectiveTo investigate the effects of heme oxygenase- 1 ( HO- 1 ) on pancreas and liver in severe acute pancreatitis(SAP) rats, and explore its probable mechanism. MethodsA total of 40 male SD rats were randomLy divided into 4 groups: control group(n = 10) ; SAP group(n = 10) ; HO-1 stimulation group (75 μg/kg hemin was injected intraperitoneally at 30 minutes after model establishment, n = 10 ) ; HO-1 inhibition group(20 μg/kg ZnPP was injected intraperitoneally at 30 minutes after model establishment, n = 10). Sodium Cholate (3％) was retrogradedly injected into the pancreatic duct to produce the SAP model. To observe the histopathological changes of pancreas, liver tissues were observed and serum, pancrease and liver tissues concentration of HO-1, IL-10 and TNF-α in different groups were observed 24 h after the SAP model establishment. ResultsCompared with those in SAP model group, the pathological scores were lower in HO-1 stimuLation group[ (7.50 ±0.58) vs (10.50 ±0. 71) ; ( 1.20 ±0.42) vs (1.70 ±0.48) ]( P ＜ 0.05 ), and the serum, pancreas and liver tissues HO- 1 [ (0.97 ± 0.02) ng/mL, (0.78 ± 0.09) ng/mL,(0.73 ±0.05) ng/mL]and IL-10[(101.72 ±2.63) ng/mL, (63.58 +1.02) pg/mL, (169.40 ±3.06) pg/mL ]concentrations were significantly elevated in HO- 1 stimuLation group ( P ＜ 0.05 ), while the serum, pancreas and liver tissues TNF-α [ (22.85 ± 1.74) pg/mL, (26.50 ± 1.3) pg/mL, (35.88 ±0.98 ) pg/mL]concentrations were significantly decreased in HO-1 stimuLation group (P ＜ 0.05 ). Compared with those in SAP model group, the pathological scores were higher in HO-1 inhibition group (P ＜0.05 ), and the serum, pancreas and liver tissues HO-1 and IL-10 concentrations were significantly decreased( P ＜0.05 ), while the serum, pancreas and liver tissues TNF-α concentrations were significantly elevated (P ＜ 0.05 ). CondusionThe results of the study demonstrated that HO- 1 over- expression has protective effects on the pancreas and liver in SAP. UP-regulated IL-10 expression and down-reguLated TNF-α expression might be served as a potential mechanism.

Objective To explore the effect of general intervention in improving the psychological condition of healthy pregnant women. Methods Totally 96 pregnant women who made prenatal visits in our obstetrics and outpatient department were divided into the control and the intervention group stochasti-cally. The intervention group started from first prenatal visit. The general intervention measures included cognitive intervention, the behavioral intervention, family coping intervention and psychological intervention with self-designed relaxation exercises. While conventional prenatal visit, propaganda and nursing were im-plemented to the control group.Self-made general questionnaire and symptom checklist 90 (SCL-90)were used to survey and analyze the results. Results Post-natal depression and anxiety of the control group was obviously higher than that of the prenatal. The Post-natal obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility, terror and bigotry in the intervention group were greatly alleviated. Com-pared with the control group, obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility and terror of the intervention group were significantly different (P<0.05). The depression improved while the difference was not evidently differenL Conclusions Delivery had great influence on the psychological status of women,especially anxiety and depression. General intervention measures like psychological relax-ation exercises can improve the psychological condition of healthy pregnant women obviously,especially de-pression.

Objective · To evaluate the efficacy and safety of prophylactic phenylephrine in parturients prone to develop spinal hypotension.Methods · Fifty parturients undergoing elective cesarean delivery whose preoperative positional mean arterial pressure (MAP) change from supine to right lateral position were bigger than 8 mmHg (1 mmHg=0.133 kPa) were randomly allocated into 2 groups, i.e. high-risk prevented group (group A) and high-risk control group (group B). Another 25 parturients whose positional MAP change were smaller than 8 mmHg were allocated into low-risk prevented group (group C). After spinal anesthesia, phenylephrine (50 μg bolus and 50 μg/min infusion) was given immediately to group A and C, and the pump speed was adjusted to 25 μg/min 10 min later till fetuses were removed. Normal saline with the same volume and pump speed was given to group B. The incidences of hypotension, reactive hypertension, and bradycardia, the occurrence of nausea and vomiting, and Apgar scores at 1 min and 5 min of three groups were compared. Results · The incidence of hypotension in group A was 28%, 76% in group B, and 16% in group C. Group A and C were significantly lower than group B (P<0.01). The reactive hypertension rate was 4% in group A and 28% in group C. There was a difference between these two group (P=0.015). There were no significant differences among 3 groups in Apgar scores at 1 min and 5 min (P>0.05). Conclusion · Prophylactic phenylephrine in the paturients prone to develop spinal hypotension reduces the incidence of spinal hypotension without obvious adverse effects on the paturients and neonates.

Objective:To compare the effectiveness of fire needle versus Western medicine in the treatment of herpes zoster. Methods:Randomized controlled trials comparing fire needle with Western medicine in the treatment of herpes zoster were identified using 8 databases. A meta-analysis was performed using RevMan 5.3 software. Results:Eight trials involving 569 patients were included in this meta-analysis, and the results showed that fire needle was superior to Western medicine comparing the effective rate [risk ratio (RR)=1.13, 95％ confidence interval (CI): 1.06 to 1.20;P=0.0002], the visual analog scale (VAS) score [mean difference(MD)=–7.95, 95％ CI: –10.71 to –5.20;P<0.00001], time of pain disappearance (MD=–7.61, 95％CI: –9.38 to –5.84;P<0.00001), time of blister-stop (MD=–1.34, 95％CI: –1.51 to –1.18;P<0.00001), time of crusted scab (MD=–2.92, 95％CI: –3.62 to –2.23;P<0.00001), and time of scab off (MD=–4.64, 95％CI: –5.83 to –3.46;P<0.00001). In addition, a significantly lower incidence of postherpetic neuralgia was found in the fire needle group in 30 d (RR=0.23, 95％CI: 0.11 to 0.51;P=0.0002) and 60 d (RR=0.33, 95％CI: 0.12 to 0.91; P=0.03) after treatment. Conclusion:Fire needle has a favorable effect in increasing the effective rate, relieving pain, recovering skin lesions and decreasing incidence of postherpetic neuralgia in the treatment of herpes zoster. However, considering the limitations in this study, the findings should be interpreted cautiously.

OBJECTIVETo get a complete cDNA sequence of B2 and evaluate the correlation on structure and expression between B2 and insulin like growth factor binding protein related protein 1 (IGFBP-rP1) in colorectal carcinomas, paired normal tissues, adenomas, tissues adjacent to the tumor, and colorectal carcinoma cell lines.

METHODS5'RACE (rapid amplification of cDNA end) was applied to get the sequence of the 5' end of B2. Semi-quantitative RT-PCR and immunohistochemistry were used to detect the expression of B2 in colorectal cancer tissues and cell lines (SW480, SW1116, SW620, HCT8, CoLo205 and LoVo).

RESULTSA sequence of 1,125 bp was obtained by combining the sequence from 5'RACE product and the known sequence of B2. It shared 1,122/1,125 identities with IGFBP-rP1. At the level of mRNA, the expression of B2/IGFBP-rP1 was high in colorectal carcinomas, moderate in adenomas and tissues adjacent to tumor, low in normal tissues (P < 0.05). Five cell lines except SW480 showed no expression of B2/IGFBP-rP1. A significant difference was obtained in the immunoreactivity of B2/IGFBP-rP1 between normal tissue and cancer (P < 0.05). In 28.9% (22/76) samples, cancer cells locating at the invasive front of cancer nest had a stronger staining of B2/IGFBP-rP1 than those surrounding the lumen. These samples had also an increased frequency of lymph node metastases, increased depth of invasion and a stronger staining of B2/IGFBP-rP1 than in other samples (P < 0.05).

CONCLUSIONSB2 is the same gene as IGFBP-rP1. Overexpression of B2/IGFBP-rP1 may play an important role in the initiation and promotion of colorectal cancer. Its overexpression in invading tumor cells may be linking with an increased potential of invasion.

OBJECTIVETo screen the differentially methylated DNA sequences between mucosa adjacent to colorectal cancer (MACC) and normal colonic mucosa.

METHODSThe methylated DNA sequences were enriched by methylation CpG islands amplification (MCA), and the differentially methylated DNA sequences between MACC and normal colonic mucosa were isolated by representational difference analysis (RDA). Similarities between the separated fragments and the human genomic DNA were analyzed with BLAST program system in GenBank. With the separated fragment 1A12 as probe, dot blot was used to study its distribution between RDA products (No. 1-4 rounds), MACC (tester) and normal colonic mucosa(driver).

RESULTSTwenty-five differentially methylated DNA sequences were obtained. Preliminary studies indicated that 1A01 fragment was concerned with two different genes (LOC256866 and CECR7), it was located in the first exon of CECR7. 1A12 fragment was located in 5 flanking region of GR6 gene. By dot blot with 1A12 probe, hybridized signals were detected in MCA product of MACC and RDA products of No. 1-4 rounds, respectively. No signal was detected in MCA product of normal colonic mucosa.

CONCLUSIONThe differentially methylated DNA sequences can be isolated effectively between two different tissues with MCA coupled with RDA. Different methylated DNA fragments exist between MACC and normal colonic mucosa and these fragments may be concerned with colorectal cancer.
