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.

Objective To evaluate the effects of different doses of lidocaine on suppressing fentanyl-induced cough and determine a safe suppressing dose.Methods Two hundred patients undergoing general anesthesia were randomized to four groups evenly.The following medications were given within ten seconds:normal saline 10ml (groupⅠ,control group),lidocaine 1 mg/kg (groupⅡ),lidoeaine 1.5 mg/kg(groupⅢ),lidocaine 2mg/kg (groupⅣ).Toxic symptoms of lidocaine were recorded within lmin after the administration of lidocaine,then fentanyl 3?g/ kg was given intravenously within 5 seconds.Cough incidence and cough grade were recorded within 2rain after the administration of fentanyl.Systolic blood pressure (SBP),diastolic blood pressure (DBP),heart rates (HR),and satu- ration of pulse oximeter(SpO2) were recorded during different time points of induction,all recorded data were anal- ysed by the statistical software,P value

OBJECTIVETo investigate the total energy intake, the energy from milk and other foods in the infants aged 4 to 12 months and analyze the factors related to the energy intake.

METHODSTotally 132 infants aged 4 months, who were brought for serial measurements to the Department of Primary Child Care, from November 2004 to March 2005 were enrolled into this study and were serially followed up until 12 months of age. The infants were divided into 3 groups, group A, age 4-5 months; group B, age 6-8 months; group C, age 9-12 months. The weights and the recumbent body lengths were measured by two professional staff members. The assessment of physical growth of the infants was done by using the CDC2000 reference. As the changes of Z score on weight for age (Delta WAZ) were < -0.67 during the two visits, the participation of the infants to this study was discontinued. The dietary intakes of the infants were calculated according to 24 h dietary records or after weighing foods for sequential 3 days,

RESULTS(1) When the Delta WAZs of the participated infants were between 0.67 and -0.67, the food intakes among three groups were 119-128 g/(kg.d), the protein intakes were 1.82 g/(kg x d), 2.76 g/(kg x d) and 3.52 g/(kg x d), respectively. The milk intakes were 76-114 g/(kg x d), which accounted for 93% of energy intakes in group A, 64% in group B and 56% in group C. The energy intakes of the 3 groups were 83.9 kcal/(kg x d), 81.6 kcal/(kg x d), and 85.8 kcal/(kg x d), respectively, which were almost similar to WHO 2003 recommendations, and lower than that of Chinese RNI. (2) The data from multiple linear regression analysis showed that the food intakes and the energy density were the most important factors related to energy intakes. The energy density of all foods was 0.6-0.8 kcal/g.

CONCLUSIONS(1) The growth of the infants was within the normal range as the energy intakes were 82-86 kcal/(kg x d). (2) The infants may need 900-750 g/d of milk to meet the basic requirements of energy and protein. (3) The food intakes and the energy density were the most important factors related to the energy intakes, the appropriate energy density for infants is 0.6-0.8 kcal/g.

Objective To explore the clinical application of percutaneous endoscopic gastrostomy in gastroin- testinal nutrition among critically ill patients.Methods Twenty-two patients were undertaken percutaneous endo- scopic gastrostomy under the lead of gastroscope.The puncturatio site was located in anterior wall of stomach.Results All the procedures were performed successfully for one time.Intraoperational blood pressure was very steady.At the same time,intraoperational SpO_2 of the patients all exceeced 97%.The bleeding amount and operation time were respectively (3.8?1.9) ml and (15.5?2.3) min.Severe complications such as gastrostoma,gastrocolic fistula, pneumoperitoneum,refluxing or aspiration of gastric juice,inhalant pneumonia didn't occur after the operation.Con- clusion Percutaneous endoscopic gastrostomy was safe and feasible among critically ill patients who needed gastroin- testinal nutrition because of its slight injury,little bleeding and shorter operational time.

ObjectiveTo investigate the role of platelet-derived growth factor(PDGF) and its receptor in the development of hypertrophic scar. MethodsThe expression of PDGF and its receptor were detected in biopsy specimens of 9 pieces of normal skin, 7 pieces of granulation tissue of burn wound and 34 pieces of hypertrophic scar by immunohistochemical staining using specific polyclonal antibodies.ResultsPDGF and its receptor markedly increased in granulation tissue and hypertrophic scars, reaching the peak in the hypertrophic scars within 6 months and then decreased after the peak, whereas PDGF and its receptor expressed weakly in only a few normal skin specimens, and the differences were significant(P<0.05).ConclusionsThe increasing expression of PDGF and its receptor may be related to the development of hypertrophic scar.

OBJECTIVETo investigate the method and the outcome of the acetabular reconstruction in the Crowe III dysplastic hip.

METHODSFrom January 2001 to June 2007, 43 cases (54 hips) were diagnosed osteoarthritis secondary to Crowe III dysplastic hip. Total hip arthroplasty was performed in all cases. The Harris score was 39 pre-operation. The method of the acetabular reconstruction included acetabular deepening (group A), medial-wall osteotomy (group B), femoral head bone grafting (group C). Radiography data and Harris score were taken to evaluate the clinical outcome.

RESULTSThe method of the acetabular reconstruction included acetabular deepening in 27 cases (34 hips), medial-wall osteotomy in 12 cases (15 hips), femoral head bone grafting in 4 cases (5 hips). Forty cases were followed up by the mean time of 29 months. The bone union time of the osteotomy and bone grafting were 4 - 5 months postoperation. In the three groups the obliquity angle of the cup were (41.0 +/- 7.5) degrees , (46.0 +/- 7.7) degrees , (39.0 +/- 11.0) degrees ; the anteversion angle of the cup were (10.0 +/- 2.8) degrees , (9.0 +/- 2.5) degrees , (4.0 +/- 1.9) degrees ; the rotation center of the hip was shift superiorly (8.4 +/- 3.6) mm, (7.3 +/- 2.6) mm, (1.2 +/- 0.5) mm; the rotation center of the hip were shift internally (7.0 +/- 1.5) mm, (9.9 +/- 1.7) mm, (-2.7 +/- 1.2) mm, and the Harris score were 89, 91, 86 at the follow up. The complication included deep venous thrombosis in 2 cases, pulmonary embolism in 2 cases, sciatic nerve palsy in 4 cases.

CONCLUSIONAcetabular deepening, medial-wall osteotomy, femoral head bone grafting can be used in reconstruction of the acetabular in the Crowe III dysplastic hip.

Mammalian cells are prone to apoptosis when cultured in large scale for production of biopharmaceuticals. And this will reduce production duration and result in high cost of production. Apoptosis is triggered by various factors, and delicately regulated by a set of genes. Bcl-2, a component integrated in mitochondria membrane, is an important member of these genes. By maintaining the integrity of mitochondria membrane, Bcl-2 keeps cytochrome C from releasing into cytoplasm, and thus blocks the activation of caspases, and subsequent onset of apoptosis. Over-expression of Bcl-2 has proven to be useful in blocking apoptosis in various cell lines, including CHO, hybridoma, myeloma, lymphoma and insect cells. Ammonia, a metabolite of cultured cells, however, showed apparent pro-apoptosis activity. In living cells, ammonia can be utilized by glutamine synthetase (GS) to synthesize glutamine, and thus lower the concentration of ammonia in medium, and its negative effects. Glutamine is essential to living cells. If not added into medium, glutamine can only be synthesized by GS, which makes GS a qualified selection marker. This marker can be used for gene amplification by adding into medium increased concentration of MSX, an inhibitor of GS. In this study, we over-expressed Bcl-2 using GS amplification in a recombinant CHO cell line stably expressing human interferon-beta. The modified cell line, with higher expression of Bcl-2 and lower production of ammonia, exhibited good anti-apoptosis quality and higher interferon-beta production in continuous culture.

Photodynamic therapy (PDT), because of its good targeting, minimal invasion, and safety, is becoming a very active area in cancer prevention and treatment, in which the photosensitizers have proved to be the core element for PDT. We developed a new HPLC method for analyzing porphyrin photosensitizers using Shiseido Capcell PAK C18 (150 mm x 4.6 mm, 5 µm) as the column at 30 °C, methanol-1% aqueous solution of acetic acid as the mobile phase in a flow rate of 1.0 mL · min(-1) in a gradient elution mode, and the detection wavelength at 380 nm. This method, showing good specificity, precision, accuracy and robusty via methodology validations, can be applied to the purity test and assay of porphyrin photosensitizers, and has played a key guide role in the R&D of the new porphyrin photosensitizer--sinoporphyrin sodium.

OBJECTIVETo investigate the early predictive indices of critical condition in infants and young children with severe pneumonia, and to provide reference for diagnosis and treatment of the disease.

METHODSClinical data were collected on 411 patients (aged 1-36 months) with severe pneumonia who were admitted from January 2009 to December 2011, and multivariate logistic regression analysis was performed using 23 potential indices. These cases were divided into a critical group of 139 cases who died in hospital or needed rescue or mechanical ventilation during the course of disease and an ordinary group of 411 cases.

RESULTSEight indices with statistical significance were selected to predict the critical condition after multivariate logistic regression analysis, including hypocalcemia with the highest odds ratio (OR) (11.488), followed by sinus tachycardia (7.506), congenital heart disease (5.977), brain disorder symptoms (5.182), premature birth (4.978), blood potassium abnormality (2.910), metabolic acidosis (2.489) and malnutrition (2.048).

CONCLUSIONSThe predictive indices of critical condition in infants and young children with severe pneumonia are hypocalcemia, sinus tachycardia, congenital heart disease, brain disorder symptoms, premature birth, blood potassium abnormality, metabolic acidosis and malnutrition. The infants and young children with these risk factors need intensive care.

The proteins encoded by the Herpesviridae β-gene play a critical role in the replication stage of the virus. In this paper, phylogenetic analyses provided evidence that someβ-gene products, such as UL2 and UL23 from HSV1, have their homologous genes in its family, and also exist in prokaryotic organisms, indicating that these viruses appear to have been assembled over evolutionary time by numerous independent events of horizontal gene transfer.
