OBJECTIVETo investigate the quality of life of cleft lip and/or palate children's parents and discuss the factors to provide the oretical basis for improving the quality of life of these parents and promoting the healthy growth of children with cleft lip and/or palate.

METHODSA total of 115 parents whose children had cleft lip and/or palate surgery treatment were selected as the experiment group, and another 198 parents (with healthy children having a similar age with those in the experiment group) as the control group. The experiment group was divided into three subgroups according to different types of cleft lip and/or palate: cleft Lip (CL), cleft palate (CP), cleft lip and palate (CLP). The experiment group and the control group were both divided into four subgroups according to age: 0-1, 1-3, 3-6 years old, and more than 6 years old. The experiment group and the control group were both divided into three subgroups according to education: junior middle school and the following, high school and technical secondary school, junior college degree or above. The GQOLI-74 scale was selected to assess the experiment group and the control group. SPSS 16.0 software was used to analyze data.

RESULTS1) The experiment group had no significant difference with the control group in terms of the overall score and the scores of various children ages. 2) The scores of every item had no significant difference in CL, CP, CLP subgroup (P > 0.05). 3) The quality of life scores and scores of psychological function dimension and social function dimension of parents with 3-6 years old patients were obviously lower than those of parents with more than 6 years old patients (P<0.05). The scores of social function dimension of parents with 0-1, 1-3, 3-6 years old patients were obviously lower than those of parents with more than 6 years old patients (P < 0.05). The other items had no significant difference. 4) The scores of material life dimension and social function dimension of parents with junior college degree or above were higher than those of parents with junior middle school degree and the following (P < 0.05). The scores of social function dimension of parents with high school and technical secondary school degree were higher than those of parents with junior middle school degree and the following (P < 0.05).

CONCLUSIONNo difference was observed in the quality of life between cleft lip and/or palate children's parents and normal group. The parents with the low age children with cleft lip and/or palate and low-levels of education need more help and support to improve quality of life.

The paper is aimed to establish a method of residue analysis for thiamethoxam and to study its degradation dynamic and final residue and its standard of safe application of thiamethoxam on Lonicera japonica. Samples extracted with methanol by ultrasonication were purified with dichloromethane by liquid-liquid extraction and SPE column and analysed by HPLC-UV. The results showed that average rate was 84.91%-94.44% and RSD 1.74%-4.96% with addition of thiamethoxam in respectively diverse concentration, which meets inspection requirement of pesticide residue. Two kinds of dosages of thiamethoxam were treated- varying from recommended dosage (90 g x hm(-2)) to high dosage (135 g x hm(-2)), Results of two years test showed that thiamethoxam was degraded more than 90% seven days after application and the half - life period of thiamethoxam was 1.54-1.66 d. The digestion rate of thiamethoxam was fast in the L. japonica. The recommended MRL of thiamethoxam in the L. japonica is 0.1 mg x kg(-1), the dosage of 25% thiamethoxam WDG from 90-135 g x hm(-2) is sprayed less than three times a year on L. japonica and 14 days is proposed for the safety interval of the last pesticide application's and harvest's date.

Objective To study the effects of granisetron hydrochloride on vasovagal syncope(VVS) in rabbits.Methods Twenty-four healthy New Zealand rabbits were divided stochastically into control group and intervention group,12 in each group. The control group was injected intravenously with normal saline. The intervention group was injected intravenously with granisetron hydrchloiride.Rabbit VVS models were established,each was taken at 4 points in time in the bloodletting process:T1,T2,T3,T4,to compare the bloodletting time,the concentration of 5-hydroxytryptamine(5-HT) in T2,T3,T4 and the total blood volume between the groups,and monitor the heart rate, blood pressure during the entire process.Results 1.The time of intervention group in T2,T3,T4 was longer than the time of control group obviously(P

This study aimed to examine the functional role of microRNA-20 (miR-20) and its potential target,Kir6.1,in ischemic myocardiocytes.The expression of miR-20 was detected by real-time PCR.Myocardiocytes were stained with terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) reagent for apoptosis evaluation.Western blotting was used to detect the Kit6.1 protein in ischemic myocardiocytes transfected with miR-20 mimics or inhibitors.Luciferase reporter gene assay was performed to confirm the targeting effect of miR-20 on KCNJ8.The results showed that miR-20 was remarkably down-regulated,while the KATP subunit Kir6.1 was significantly up-regulated,during myocardial ischemia.The miR-20 overexpression promoted the apoptosis of ischemic myocardiocytes,but showed no such effect on normal cells.Under ischemic condition,myocardiocytes transfected with miR-20 mimics expressed less Kir6.1.On the contrary,inhibiting miR-20 increased the expression of Kir6.1 in the cells.Co-transfection of miR-20 mimics with the KCNJ8 3’-UTR plasmid into HEK293 cells consistently produced less luciferase activity than transfection of the plasmid alone.It was concluded that miR-20 may regulate myocardiac ischemia by targeting KATP subunit Kir6.1 to accelerate the cell apoptosis.Therefore miR-20 may serve as a therapeutic target for myocardial ischemic disease.

OBJECTIVEA molecular technique based on quasispecies analysis for tracing postexposure HIV transmission was applied in an investigation of a possible case of HIV transmission after blood transfusion.

METHODSSixteen plasma specimens were collected from 3 HIV infections (T1-T3) involved in a possible HIV transmission chain and 13 HIV/AIDS (C1-C13) controls. The RNAs were extracted and then amplified by RT-PCR, the PCR products were cloned and sequenced.BioEdit 6.0.7 and MEGA 4.0 software were used to analyze gene sequences, calculate gene dispersion ratio and construct phylogenetic tree.

RESULTSThe sequences of 13 specimens were successfully obtained.The HIV strains from T1, T2 and T3 were CRF07_BC recombinants, those from 5 out of the 6 controls lived in the same city with T2 and T3 were CRF07_BC recombinants as well, while those from 4 controls living in the same city with T1 were CRF01_AE recombinants. Compared with the clone sequences from T1, the mean gene dispersion ratio of T2 was the least (2.0%), followed by C12 (2.8%) , T3 (2.9%) and others. The phylogenetic tree showed that all clones from T1, T2, T3 and C12 might cluster together,and implied that the direction of HIV transmission was from T3 to T2, and then to T1.

CONCLUSIONThe results support the possible epidemiological clue that HIV was transmitted from T3 to T2, and then to T1, indicating that molecular epidemiological investigation could provide more direct evidence for tracing postexposure HIV transmission.

AIMTo provide experimental basis for clinical use of cryopreserved dendritic cells (DCs) by investigating the biological properties of cryopreserved DCs derived from cord blood.

METHODSThe biological discrepancies between unfrozen DCs (UFDC) derived from unfrozen cord blood (UFCB) and DCs from cryopreserved cord blood (CPCB) or cryopreserved DCs (CPDCs) were explored by morphological observation and immunophenotype analysis. Moreover, the stimulating index (SI) in mixed lymphocyte culture and cytotoxic eliminating rate (ER) were measured by MTT.

RESULTSThe TBR of CPCB and CPDCs were 95.8% and 88.7% respectively. Compared to UFCB, CPCB differentiated toward DCs in a delayed and decreased mode, displayed lower expression of CD1a, CD83 and HLA-DR, and had reduced SI and ER. Similarly, the CPDCs became adherent DCs later and grew less in number than UFDCs. After culture, the expression of CD1a, CD83 and HLA-DR as well as SI and ER were lower in CPDCs than those in UFDCs.

CONCLUSIONThough the biological properties of CPCB and CPDCs were injured after cryopreservation, they still had relatively complete basic function. Their recoveries rate were > 85%.

OBJECTIVETo use dried blood spot (DBS) in studying the sequence and subtype analysis of HIV-1 genome.

METHODS2 ml whole blood containing EDTA anticoagulant from 20 HIV-1 infected patients were collected, then 80 microl blood was used to propare DBS. QIAamp Blood Mini kit and 10% Chelex100 resin extracted DNA genome from whole blood and DBS as well as nested PCR amplified specifically HIV-1 Gp41 region from the two kinds of DNA extraction. Software MAGE 3.0 was used to study the sequence and subtype of the PCR products.

RESULTSEligible 18 paired samples were analysed to show that 16 of them belonged to C54A, 97CNGX-7F, 98CN006 subtypes. The other two samples might belong to B. CN._. RL42 and B. US. 90WEAU160.

CONCLUSIONData showed that there were parallel results between the whole blood and DBS samples including subtype analysis, position of mutation and types of amino acid sequencing. Since DBS itself facilitated the collection, transportation and storage, it could be used as a measure to collect blood sample in resource limited area and to develop molecular epidemiologic research as well as early diagnosis on infant exposed to HIV.

Objective To evaluate the feasibility of different kinds of surgeries to treat hypopharyngeal carcinoma and investigate the methods to conduct one-stage repair after hypopharyngeal carcinoma removal. Methods Thirty nine cases of hypopharyngeal carcinoma were treated from May 2000 to Mar 2007, of which 27 were originated from pyriform sinus, 8 from postcricoid and 4 from posterior pharyngeal wall. One-stage reconstruction for hypopharyngeal and esophageal defect was done with simple and less-damaged hypopharyngeal plasty by local sewing, infrahyoid muscle flap, pectoralis major flap and supplement of esophagus by stomach. Results The defect of 18 cases was repaired by sternohyoid muscle flap, including 13 from pyriform sinus, 4 from root of tongue and 1 from posterior pharyngeal wall. Seven were repaired by substitute of esophagus by stomach, 5 by local sewing, 4 by cervical flap and 2 by pectoralis major myocutaneous flap. All the patients were successfully followed up during the survival days. Half of the cases suffered from slight deglutitory disorder after operation and recovered soon, while 2 cases were still with worse deglutitory function. All the cases were recovered with laryngeal function, and 21 cases were decannulated with normal respiration and voice, and 18 with cannula. Thirteen cases survived for more than 3 years after operation and 5 cases more than 5 years, while 14 cases died within 1 year. Thirteen cases were carried out another operations for local recurrence or metastases of lymph nodes, one of whom experienced 6 operations. The estimated 3-year survival was 43.3% (13/30), and 5-year survival was 37.5%(3/8). Conclusion Hypopharyngeal carcinoma with different site and stage can be treated by different methods, and one-stage reconstruction can be done to repair the defect of pharynx and esophagus with satisfactory functional restoration and prognosis.
