Objective The absorbable haemostatic membrane was used to stop bleeding during posterior spinal surgery so as to investigate the therapeutic effect and the security of the absorbable haemostatic membrane. Methods Ninety-four patients were enrolled into the experimental group and the control group. In the experimental group , the decompression wound is handled by using the regular absorbable haemostatic membrane to stop bleeding. In the control group , the conventional surgical methods , such as coagulation , brain cotton and other methods were used to stop bleeding. After the operations , patients in two groups were given indwelling vacuum drainage tube. The post operation vacuum pipe drainage , the drainage tube removing time , the incidence of postoperative complications after removing drainage tubes , the reoperation number , vital signs after 24 hour (temperature, respiration, pulse, blood pressure), and laboratory tests (blood count, coagulation function parameters) were determined and compared between two groups. Results Both the vacuum drainage at 24 hours post operation and the total vacuum drainage post operation were significantly reduced in the experimental group(P < 0.05, respectively). No significant differences in the coagulation function parameters were found between both two groups. Conclusion The absorbable haemostatic membrane may be applicable for spinal surgery.

Zinc finger nuclease (ZFN), which is a chimeric fusion structure between a Cys2-His2 zinc-finger protein (ZFP) and the cleavage domain of Fok I endonuclease, can be used to introduce targeted double-stranded breaks (DSBs). ZFN-mediated cleavage leads to mutations when double-stranded breaks are repaired by homologous recombination (HR) or nonhomologous end joining (NHEJ). In recent years, ZFNs are widely used in the fields of genetic research. In this review, the methodology and technical advantages of ZFNs were briefly discussed.

Objective To investigate whether elevated pre-procedural C-reactive protein (CRP) and Interleukin-6 (IL-6) concentrations may be relevant to early outcome in patients undergoing PCI.Method 100 consecutive patients undergoing pereutaneuous coronary intervention (PCI) were included in our study.Peripheral blood samples for CRP and IL-6 testing were withdrawn before PCI.Acute vascular complications resulted from PCI were determined by subsequently coronary angiography.The early coronary events during hospitalization were clinically followed.Results Thirty patients developed acute vessel occlusion,and another one developed subacute coronary thrombosis at 2 days after PCI.Increased levels of CRP correlated well with the occurrence of vascular complications as regards the significant difference existing amongⅠvsⅢandⅠvsⅣquartile groups,P

BACKGROUNDThe abnormalities of coronary arteries, though rare and sometimes benign, may first present clinically as myocardial infarction or sudden death. Multi-detector computed tomography (MDCT) is a non-invasive test that is highly suitable for detecting these anomalies. The study aimed to review the 64-MDCT appearance of the coronary artery anomalies in 66 patients and to discuss the clinical importance of these anomalies.

METHODSIn 6014 consecutive patients examined over 12 months by 64-MDCT for the study of coronary artery disease, 66 were diagnosed for coronary artery anomalies. All patients were symptomatic for one or more of the following diseases: chest pain, dyspnoea, palpitations, arrhythmia and myocardial infarction. Nine patients had undergone a coronary angiography. All the CT images were evaluated by two radiologists and one cardiologist. The right coronary artery (RCA) and the conus branch arising separately, myocardial bridging and duplication of arteries were not analysed in our study.

RESULTSThe incidence of coronary artery anomalies found in our study group was 1.097%. In the selected patients, seven different types of coronary anomalies were found by 64-MDCT examination. The high takeoff, origin of the coronary artery from the opposite or noncoronary sinus with an anomalous course, and coronary artery fistula were the three common forms of anomalies (n = 16, 18 and 16, respectively). Compared with the results of the coronary angiography, the number of the drainage sites of two coronary artery fistula was less in MDCT images (3 small sites in total). In all cases, coronary artery computed tomography angiography (CTA) technique was able to recognize the origin of the coronary artery, its three-dimensional course and its spatial relationship with the adjacent structures. Conventional coronary angiography in two cases, however, was unable to provide sufficient information for correct and complete diagnosis.

CONCLUSIONSIn conclusion, the study showed that 64-MDCT, especially the volume rendering technique (VRT), may be useful for the assessment of complex variations, even if the conventional angiography may not be sufficient. It may be considered as the first-choice imaging modality when an anomalous coronary artery is suspected.

Objective To investigate the iodine nutritional status of residents in coastal areas of Fujian province,and to provide evidence for effective implementation of preventive strategy of scientific supplying of iodine.Methods In 2009,in Fujian province,6 cities were selected,then one area in every city was selected.A District Office was selected in every area,and then 1 Residents Committee in every District Office was selected.Eleven counties were selected,1 township in each county was selected,and then 1 village in each township was selected.Thirty families were selected in each Residents Committee(village),and then iodine content in household drinking water and salt were tested.The per capita salt intake in the households was calculated using 3 days weighing method.Twenty adults aged 18 to 45 were selected to test their urinary iodine; thirty pregnant and lactating women and 50 children aged 8 to 10 in each street(township ) were selected to test their urinary iodine(UI).Results One hundred and fifty three,30,94,183 and 62 families in coastal cities,inland cities,inland rural areas,coastal rural areas,and coastal mountain areas were surveyed,respectively.The median iodine content of salt was 28.4 - 30.8 mg/kg.The coverage rate of iodized salt and the qualified iodized salt consumption rate were all above 90％ in coastal cities,inland cities,inland rural areas and coastal mountain areas.The coverage rate of iodized salt and the qualified iodized salt consumption rate were 86.9％(159/183) and 83.6％(153/183) in coastal rural areas.In coastal cities,coastal rural areas,inland rural areas,inland cities and coastal mountain areas,258,300,110,160 and 101 children aged 8 - 10 were surveyed,respectively,and the median UI were 191.0,165.6,267.7,269.0 and 161.0 μg/L,respectively.One hundred and one,123,118,63 and 41 adults were surveyed,respectively,and the median UI were 197.6,203.4,174.7,302.8 and 154.9 μg/L,respectively.One hundred and fifty one,181,50,101 and 63 pregnant were surveyed,respectively,and the median UI were 156.5,141.7,116.2,163.0 and 126.2 μg/L,respectively.One hundred and fifty four,184,40,111 and 70 lactating women were surveyed,respectively,and the median UI were 130.3,118.8,110.9,154.6 and 175.9 μg/L,respectively.Conclusions The iodine nutritional level of residents in coastal areas is suitable,and iodine excess does not exists.Coastal areas still need to supply iodized salt.We should be highly concerned about the status of iodine nutrition of pregnant women and put this part of population into routine monitoring.

OBJECTIVETo explore the effect and the mechanism of Danhong Injection (DI), Ligustrazine Injection (LI), and adsorbable biomembranes in preventing the adhesion of tendons and tissues.

METHODSTotally 120 patients all suffering from simple flexor digitorum tendon rupture on the hand zone two damaged by sharp weapons were randomly assigned to Group A (Dikang adsorbable biomembrane), Group B (Tianxinfu adsorbable biomembrane), Group C (Tianxinfu adsorbable biomembrane + Ligustrazine group), and Group D (Tianxinfu adsorbable biomembrane + DI group) in accordance with random digit table, 30 cases in each group. Indicators such as total active movement (TAM) of the hand tendon, Minnesota manual dexterity test (MMDT), and finger flex strength test (FFST) were observed.

RESULTSThe TAM and the favorable rate were higher in Group C and D than in Group A and B at post-operative 4 and 8 week (P < 0.05, P < 0.01). There was no statistical difference between Group C and D (P > 0.05). Each index of MMDT was lower in Group C and D than in Group A and B (P < 0.05). There was no statistical difference in FFST among all the 4 groups (P > 0.05).

CONCLUSIONSCombined application of LI or DI with Tianxinfu adsorbable biomembranes could effectively prevent the adhesion of tendons. DI showed equivalent effect as LI did. Besides, the combined application was superior in preventing adhesion to using Xintianfu adsorbable biomembrane or Dikan adsorbable biomembrane alone.

The main factors which affected the isolation, purification and cultivation of Pinellia cordata protoplasts from leaves were studied. The results indicated that the optimum enzyme solution for P. cordata leaves was 13% CPW + 1.0% Cellulose +0.1% Pectolase, at pH 6.0, temperature (25-28 degrees C ) for 4 h. The sucrose density gradient centrifugation was adopted to purificate the protoplasts collected, when 25% sucrose was used as mediator, centrifugating at 500 rpm for 10 min. When the protoplasts were shallow liquid and liquid-solid double layer cultured on the medium of MS + 0.5 mg x L(-1) 6-BA + 0.25 mg x L(-1) NAA + 13% mannitol at the density of 2.5 x 104 protoplasts/mL, or fed and nursed cultured at the density of 100-500 protoplasts/mL, cell division could be observed for 3 days; granular calli appeared for 30 days. Calli was proliferated on the medium of MS + 0.5 mg x L(-1) 6-BA + 0.25 mg x L(-1) NAA solidified by 0.55% agar, and differentiated and regenerated after 5-6 months. Plant generation of P. cordata is successfully established.

OBJECTIVETo explore the relationship between the depression symptoms and occupational stress in occupational populations.

METHODSDepression symptoms were measured by using the center for epidemiological survey-depression scale. The occupational stress instrument were employed to investigate the stressors, personalities, social support, and coping strategies as well as the subject's age, length of service, sex, educational level and marriage status. Chi(2) test was used for analyzing the difference of depression. The multiple covariance analysis was used for testing the difference of stressors, personalities, social support, and coping strategies among the groups with different scores of depression. The variables obtained in the optional prediction equation were identified by multiple stepwise regression analysis.

RESULTSThe incidence rate of definite depression symptoms was 40.2%. The total average score was 21.74 +/- 8.99. Henan province had the highest incidence rate of depression symptoms, 43.8%, Hebei 39.4%, and Beijing the lowest, 23.4%. The male workers had the higher incidence rate of depression symptoms, 43. 0% than female, 35.4% (P < 0.01). The older group had the lower incidence rates of depression symptoms, compared with the younger group (P < 0.01). The workers divorced or with the bereft spouse had the higher incidence rate of depression symptoms than the workers married and unmarried (P < 0.05). The workers with middle school education had the higher incidence rates of depression symptoms than those with master degree. Incidence rates in the most occupational groups were more than 30%. The significant difference was shown between the different jobs (P < 0.01). The difference of the adjusted means among three groups of different depression score were analyzed. The results showed the workers with definite depression symptoms had the higher scores than the other two groups in physical factors, role ambiguity, role conflict, job monotony, mental load, responsibility for persons, job future ambiguity, job hazards, type A behavior and work locus of control, and social support (P < 0.05, P < 0.01). The former had the lower scores than the other two groups in the scores of promotion, participation, autonomy, task identity, feedback, friendship opportunity, speed control, training adequacy, challenge, self-esteem, organizational commitment, and coping strategies. Fifteen variables entered the predictive equation of depression score explaining 33.1% of variance.

CONCLUSIONThere are serious mental health problems in the occupational population in our country. Stressors and personalities affect the mental health.
