OBJECTIVETo explore the expression of polymorphonuclear leucocyte adhesive molecules CD11b/CD18 and to study the possible mechanism of Chinese herbal medicine (TCM) for activating blood circulation to remove stasis in preventing vascular diseases.

METHODSForty-nine patients with diabetes mellitus (DM) but with no complications of hypertension and nephropathy were randomly divided into the treated group (26 patients treated by TCM) and the control group (23 patients treated by conventional treatment). They were treated for 3 months. The changes of urinary albumin excretion rate (UAER), CD11b/CD18 expression and tumor necrosis factor-alpha (TNF-alpha) concentration before and after treatment were observed.

RESULTSThe CD11b/CD18 expression and TNF-alpha concentration in DM patients were higher than those of normal range (P < 0.01). After treatment, the UAER, CD11b/CD18 expression and TNF-alpha concentration lowered significantly in the treated group (P < 0.01), but unchanged in the control group. Correlation analysis showed that the lowering of UAER was positively correlated with decreasing of CD11b/CD18 (r = 0.64, P < 0.01) and TNF-alpha (r = 0.56, P < 0.01).

CONCLUSIONExpression of CD11b/CD18 increases in patients with DM type 2. The mechanism of Chinese herbal medicine for activating blood circulation to remove stasis in preventing vascular disease in possibly related with its effect in inhibiting CD11b/CD18 expression.

BACKGROUNDDuring scanning of the right hypochondrium and right intercostal regions with an ultrasonic transducer, several ultrasonic images of oblique sections are obtained. It is still a challenge for ultrasonography to divide these non-conventional sections into an accurate hepatic segmentation pattern. The aim of this research was to investigate the value of the virtual hepatic segment model (VHSM) in assisting the ultrasonic localization of space-occupying hepatic lesions.

METHODSVHSM was constructed via 3D reconstruction according to the first Chinese visible human dataset. Preoperative ultrasonography, contrast-enhanced CT scan and VHSM techniques were performed in 100 patients with space-occupying focal lesions in the liver parenchyma for segmental localization. The results of these three techniques were compared with the operative findings.

RESULTSVHSM was successfully detected on 2D sectional images by 3D reconstruction through surface rendering and volume rendering. The model could simulate ultrasonic directions to conduct a virtual dissection on any section plane, and fine liver segmentation could be displayed in any virtual plane. In 100 patients, there were 112 liver space-occupying focal lesions distributed in 148 liver segmentations. Regarding the positioning accuracies for lesions of different sizes and the lesion segmental distribution accuracies estimated using the three methods mentioned above, ultrasonography exhibited a significantly lower accuracy than VHSM for the segmental localization of lesions (P < 0.05), and contrast-enhanced CT was not significantly different from ultrasonography plus VHSM (P > 0.05).

CONCLUSIONVHSM increased the accuracy of ultrasonic localization of space-occupying hepatic lesions, particularly in hepatic hypovascular regions.

HEV is classified into H (human) group and Z (zoonosis) group according to its compatible host. H group contains genotype 1 and genotype 2 HEV isolates which infect human only; Z group contains genotype 3 and genotype 4 HEV isolates which infect both human and animals. After analysis of amino acid sequences between ORF2 aa368 and aa606, four group-conserved sites that were all located in the neutralization region of ORF2 were identified. They are aa483, aa492, aa497 and aa599. Mutation analysis and capture PCR were then performed on these sites with a group of monoclonal antibodies. Results showed that the difference of the aa497 between H and Z groups was responsible for the maintenance of their group-specific immunodominant epitopes, probably through confirmation-dependent epitope changes. Thus, aa497 and its related change on the surface structure of HEV may play important roles in host selection by H and Z groups of HEV.

PURPOSE: Intranasal dexmedetomidine is an effective sedative for premedication and is regularly used to reduce preoperative tension and anxiety in children. This study aimed to assess the effect of intranasally adjunctive dexmedetomidine on perioperative sedative and analgesic requirements in adults. MATERIALS AND METHODS: Patients were randomly divided into four groups to receive preoperative administration of saline, intranasal dexmedetomidine 1 µg/kg and 2 µg/kg, and intravenous dexmedetomidine 1 µg/kg, respectively. Propofol and remifentanil were target-controlled infused to maintain intraoperative bispectral index at 45-55 and blood pressure at baseline value±20%. Sufentanil was administered to maintain postoperative visual analogue scale ≤3. Perioperative anesthetics requirements were compared using nonparametric tests. RESULTS: Intranasal dexmedetomidine significantly attenuated propofol requirements for anesthesia induction and maintenance in a dose-dependent manner. Patients given intranasal dexmedetomidine 2 µg/kg required less remifentanil for anesthesia maintenance. The first postoperative request for sufentanil analgesia was delayed in patients given intranasal dexmedetomidine 2 µg/kg. The anesthetics-sparing effect of intranasal dexmedetomidine was significantly weaker than intravenous dexmedetomidine at the same dose of 1 µg/kg. The incidences of adverse events, including hemodynamic instability and delayed recovery, were comparable with and without intranasal dexmedetomidine. CONCLUSION: Intranasal administration of dexmedetomidine can reduce perioperative anesthetic requirements, and a dose of dexmedetomidine 2 µg/kg produces a better effect in adults. The anesthetics-sparing effect of intranasal dexmedetomidine 1 µg/kg is less than that with the same intravenous dose of dexmedetomidine.

OBJECTIVEIn order to fully understand hepatitis c virus (HCV) genotype 3b, 1a, 2b and 6a infection in China, We built HCV 5'-noncoding region (5'-NCR) of different genotypes and subtypes.

METHODSThe classification HCV into variable genotypes (subtypes) was carried on by programs A, B and C A. Using a combination of three restriction endonuclease BHH' (BsrB I, Hae II, Hinf I) digestions at the same time. The distinct genotypes were classified into 5 groups: genotype 1 (1a, 1b), 6a, 2 (2a, 2b), genotype 3 (3a, 3b), genotype4 (4a). B. With regard to genotype 1, we could distinguish subtype 1a from 1b using BstU I digestion. C. Using restriction endonuclease Hae III, genotype 2a, 2b, 3b, 4a, 6a are differentiated respectively.

RESULTS(1) HCV genotype 1a, 1b, 2a, 2b, 3a, 3b, 4a, 6a are fully discriminated by comparison with the genotypes regular samples. (2) Of the 93 patients, HCV genotype distribution in China was 66.67% for 1b, 18.28% for 2a, 3.23% for 1b/2b, 3b, 2b respectively. 2.15% for 2a/2b, 1b/2a respectively. 1.08% for 1a.

CONCLUSIONThis research indicated that adoption of HCV 5'-NCR A B C restriction endonuclease digestions techniques, might be sensitive and efficient to detect HCV and discriminate HCV genotype (subtypes) 1a to 6a.

OBJECTIVEIt was to explore the application of the hepatitis B virus large proteins (HBV-LP) in public health physical examination through clinical testing of HBV-LP in Catering practitioners, students and soldiers of New requisition etc.

METHODS709 samples of HBV infection people were collected in public health physical examination and all collected samples were detected. ELISA was used to detect HBV serum markers (HBV-M) and HBV-LP. Real-time PCR was applied to detect quantity of HBV DNA.

RESULTS(1) The detectable results of HBV-LP and HBV DNA were no statistical significance in 709 samples. (2) The detectable results of HBV-LP and HBV DNA were also no statistical significance in different models of HBV infection patients. The values of chi2 and P were respectively 2.67, 0.60, 0.00 and 0.10, 0.44, 1.00. S/A of HBV-LP and the copies of HBV-DNA had a positive relationship (r = 0.959, P < 0.05).

CONCLUSIONHBV-LP could reflect the level of hepatitis B virus replication and be used to judge the level of hepatitis B virus replication in people of public health physical examination. HBV-LP may be worth using widely in physical examination.
