CD_(44) adhesion molecule is a cell surface transmembrane glycoprotein.It displays many varinat isoforms generated by alternative splicing of exons, including CD_(44s). and CD_(44v). It has been reported that CD_(44) adhesion molecule is strongly expressed on the surface of leukemic blasts in all acute myeloid leukemia subtypes.It has been found through in vitro study that CD_(44) monoclonal antibodies can inhibit proliferation of all acute myeloid leukemia cell lines and induce terminal differentiate or apoptosis of some cell lines to diverse extent. In this review the relationship between CD_(44v), and leukemia was analysed.

Objective:To investigate the apoptosis by thiocoraline in combination with cisplatin on cervical cell line c4-1 and Hela and its mechanism. Methods:Different concentrations of thiocoraline and cisplatin alone or in combination used for cultured c4-1 and Hela cells. The inhibition of cell proliferation was detected by MTT assay,and the apoptosis was detected by Hoechst 33342 and AO-EB staining. The expressions of the protein Bax,Bcl2,p53,p21 were detected by Western blot. The cell cycle of c4-1 and Hela cells were detected by Flow cytometry. Results: The cell proliferation activity of c4-1 and HeLa cells were inhibited obviously by different concentrations of thiocoraline and cisplatin alone or in combination. The inhibition effect was in a dose-dependent manner. Meanwhile, when the concentrations of thiocoraline and cisplatin were 10 nmol/L and 4 μmol/L, respectivity the inhibitory effect was most significant (P<0. 05);Hoechst 33342 and AO-EB staining showed that the cell apoptosis effect was more obvious on thiocoraline in combination with cisplatin. The Western blot showed that the expressions of the protein Bax,p53,p21 were significantly up-regulated, and the Bcl2 was significantly down-regulated. Conclusion:Thiocoraline combination with cisplatin could up-regulate the expression of the protein Bax,p53,p21 and down-regulation the expression of Bcl2 to inhibition the proliferation and promotion apoptosis of cervical cell line c4-1 and Hela.

Objective To analyze the risk factors related to obesity of preschool children. Methods The physical activity and eating behavior of 120 obese children aged 1～6 years were investigated with questionnaire by case control 1:1 matched. Results Obesity group spent significantly longer time to watch TV than control group, but the time for physical activity, feeding pattern during the first 4 months, the time of initial supplementary foods and the sleeping duration were not different between both groups. Conditioned logistic regression of multi-variables showed that good appetite, fast eating, overeating of carbohydrate and meat , and snacks before breakfast were the risk factors of child obesity. Conclusion The bad eating behaviors and the lack of physical activity were related to obesity in preschool children.

Objective To study the reasons and prophylaxes of conversion to laparotomy during gy-necological laparoscopic surgery. Method Clinical records of 36 cases of conversion to laparotomy out of 1143 cases of gynecological laparescopic surgery were analyzed retrospectively. Results The rate of conver-sion to laparotomy was 3.15%. The reasons of conversion to laparotomy were abdominopelvic cavity adhesion in 23 cases, technical difficulty and complication in 8 cases, malignant tumor in 3 cases, accounting for 63.89%, 22.22%, 8.33%, respectively. The rate of conversion to hparotomy in patients with a history of laparotomy was significantly higher than that without a history of laparotomy. The rate of conversion to laparoto-my in early stage of developing laparoscopic surgery was significantly higher than that in other stages. Con-clusions Abdominopelvic cavity adhesion is the primary reason of conversion to laparotomy during gyneco-logical laparoscopic surgery. Careful evaluation before surgery and improving ability of performance can de-crease the rate of conversion to laparotomy.

With the development of detection technology,point of care testing POCT) presents a tendency of diversity.However,the blood glucose meter and blood gas analyzer are still the major types of POCT in most hospitals.How to manage them effectively has become everyone's concern.The decrease in detection quality is caused by personnel,equipment,reagents,quality control and result reports.According to the baseline survey of POCT carried out in Guangzhou Women and Children's Medical Center,6 key points to improve the quality management were found.Meanwhile,the application of plan-do-check-action (PDCA) may allow access to an effective POCT management program.

Objective:To understand the mental health state of severe acute respiratory (SARS) for children from medical workers' family and to provide information on clinical psychotherapy and behavior modification during heavy spreading of infectious diseases.Methods:Each school took out two classes from grade four to six, which was from seven different sections of Xi'an, 2000 pupils were chosen randomly to complete.The observatory group (OG) and standard group (SG) include 286 and 615 primary school children whose mother is medical worker and non-medical worker, respectively. Self-made questionnaire was employed for this survey. Results:OG is significantly higher than SG on neurasthenia, fear ,depression and lower on forcer-anxiety,passiveness (P

[ABSTRACT]OBJECTIVETo investigate the effect of accurate airway humidification on hemorrhage, pharyngalgia, mucosal edema and sputum viscosity in patients with low-temperature plasma coblation-assisted tonsillectomy.METHODS58 cases were divided into three groups by using random numbers.In accurate airway humidification group, atomizing inhalation was carried out by AIRVOTM series apparatus; in oxygen atomizing group, budesonide suspension was used; in control group, saline was used. We evaluated the hemorrhage, pharyngalgia, mucosal edema and sputum viscosity in 3 consecutive postoperative days.RESULTSPharyngalgia in accurate airway humidification group and in oxygen atomizing group were both significantly reduced than that of the control group (P<0.001). Besides, in accurate airway humidification group, mucosal edema and sputum viscosity were significantly improved than that of the oxygen atomizing group (P<0.05) and control group (P<0.05).CONCLUSIONAccurate airway humidification could reduce the complications such as pharyngalgia, mucosal edema and purulent sputum after low-temperature plasma coblation-assisted tonsillectomy, and could accelerate recovery from surgery.
